243,494 | <p>I have some legacy code that uses VBA to parse a word document and build some XML output; </p>
<p>Needless to say it runs like a dog but I was interested in profiling it to see where it's breaking down and maybe if there are some options to make it faster.</p>
<p>I don't want to try anything until I can start measuring my results so profiling is a must - I've done a little searching around but can't find anything that would do this job easily. There was one tool by brentwood? that requires modifying your code but it didn't work and I ran outa time.</p>
<p>Anyone know anything simple that works?</p>
<p>Update: The code base is about 20 or so files, each with at least 100 methods - manually adding in start/end calls for each method just isn't appropriate - especially removing them all afterwards - I was actually thinking about doing some form of REGEX to solve this issue and another to remove them all after but its just a little too intrusive but may be the only solution. I've found some nice timing code on here earlier so the timing part of it isn't an issue.</p>

243,504 | <p>How would one go about capturing users keystrokes in the SMS composer on the Symbian OS, specifically for a Nokia N73 (or any of the symbian supported devices <a href="http://en.wikipedia.org/wiki/Symbian_OS#Devices_that_have_used_the_Symbian_OS" rel="nofollow noreferrer">http://en.wikipedia.org/wiki/Symbian_OS#Devices_that_have_used_the_Symbian_OS</a>)? I'm new to symbian development and I'm trying to write an application to analyse writing styles of those who send SMSs. Any information (or push in the right direction) would be great.</p>
<p>Many Thanks,</p>

243,510 | <p>Does anyone know what is wrong with this query?</p>
<pre><code> SELECT DISTINCT c.CN as ClaimNumber,
a.ItemDate as BillReceivedDate, c.DTN as
DocTrackNumber
FROM ItemData a,
ItemDataPage b,
KeyGroupData c
WHERE a.ItemTypeNum in (112, 113, 116, 172, 189)
AND a.ItemNum = b.ItemNum
AND b.ItemNum = c.ItemNum
ORDER BY a.DateStored DESC;
</code></pre>
<p>I have done T-Sql most of my career and this looks correct to me, however this query is for an Oracle database and Toad just places the cursor on the a.DateStored in the Order By section. I'm sure this is elementary for anyone doing PL/SQL.</p>
<p>Thanks!</p>
<p>[EDIT] For future reference, the error given by SQL*Plus was: "ORA-01791: not a SELECTed expression" </p>

243,528 | <p>We're looking at using Oracle Hierarchical queries to model potentially very large tree structures (potentially infinitely wide, and depth of 30+). My understanding is that hierarchal queries provide a method to write recursively joining SQL but they it does not provide any real performance enhancements over if you were to manually write an equivalent query... is this the case? What sort of experiences have people had, performance wise, with using oracle hierarchical queries?</p>

243,554 | <p>I'm currently creating a window system for XNA games from scratch. I'm developing primarily for Windows, but who knows what platforms I might support in the future. Feel free to answer if you know this for native Direct3D, since the performance semantics should be similar. If possible, consider what would change if the target platform was X-Box 360.</p>
<p>I'm making good progress, but now I am unsure on how to exactly render the windows. I came up with four approaches:</p>
<ul>
<li><p>Just render all controls directly onto the screen. This is what I do now. Controls can be animated by blending between states as long as they are not semi-transparent. I did not find a good way to animate between an arbitrary number of states (suppose a button that is currently animating from button-up to button-down and from mouse-out to mouse-over, and then it is being disabled. It should smoothly blend from its last state to the new state. With this approach, this only works if one animation is played after the last one finished, or you'll have jumps in animation.</p></li>
<li><p>Render each top-level window and all controls into a render target, and then use that to render the top-level windows with semi-transparency onto the screen. This makes semi-transparency at top-level work and is easy to manage, but doesn't change the thing with the animations.</p></li>
<li><p>Render each control into a render target, which is only updated when the control becomes dirty (i.e. must animate or the text has been changed). This way, per-control semi-transparency would work.</p></li>
<li><p>Like the previous, but in addition to solve the animation problem have a second render target for each control. Whenever an animation starts, swap render targets, so we have the state when the animation starts, and blend it with the destination state into the other render target. This should not add overhead over the previous approach, we just had twice as many render targets, of which in any given frame only one would be rendered to (at maximum). But here comes the problem: For this to work, I would need to have the "old" render target preserve its contents. This should work with good performance on Windows, but appears to have a serious performance impact on X-Box 360. On the other hand, the "preserve" bit is only necessary while an animation is active.</p></li>
</ul>
<p>And here come the actual questions. Anything that clarifies is welcome. With the performance questions, remember that this would just be the window system of a game - the game behind might use many render targets and suck up performance as well, and likely much more than the window system. Assume that we might have five top-level windows with 20-40 controls each on the screen in absolute worst-case.</p>
<ul>
<li>Which of these approaches, if any, would you recommend and why? Feel free, of course, to add another approach.</li>
<li>Is there a performance impact when just having let's say 200 or 400 render targets available, provided that only maybe 20 of them are being rendered to each frame?</li>
<li>Is the performance impact of PreserveContents really that bad on X-Box 360? How bad is it on Windows?</li>
<li>The RenderTarget2D.RenderTargetUsage property can be written to. Is switching this at runtime a good idea, to enable PreserveContents only as needed?</li>
<li>Would you (as a player) mind if control animations would jump in certain situations, like hovering over a button, moving the mouse out and then in again, so the "normal->hover" animation is played twice from the beginning because it is slower than you?</li>
</ul>

243,568 | <p>I found in a bug in an old C++ MFC program we have that calculates an offset (in days) for a given date from a fixed base date. We were seeing results that were off by one for some reason, and I tracked it down to where the original programmer had used the CTimeSpan.GetDays() method. According to the <a href="http://msdn.microsoft.com/en-us/library/14zezc9x.aspx" rel="nofollow noreferrer">documentation</a>:</p>
<blockquote>
<p>Note that Daylight Savings Time can cause GetDays to return a potentially surprising result. For example, when DST is in effect, GetDays reports the number of days between April 1 and May 1 as 29, not 30, because one day in April is shortened by an hour and therefore does not count as a complete day.</p>
</blockquote>
<p>My proposed fix is to use <code>(obj.GetTotalHours()+1)/24</code> instead. I think that would cover all the issues since this is a batch job that runs at about the same time every day, but I thought I'd ask the smart people here before implementing it if there might be a better way. </p>
<p>This is just a side issue, but I'm also curious how this would be handled if the program could be run at any time.</p>

243,572 | <p>I am configure log4net to use a composite RollingFileAppender so that the current file is always named <strong>logfile.log</strong> and all subsequent files are named <strong>logfile-YYYY.MM.dd.seq.log</strong> where <strong>seq</strong> is the sequence number if a log exceeds a certain size within a single day. Unfortunately, I have had very little success in configuring such a setup. </p>
<p><strong>Edit:</strong></p>
<p>My current configuration is pasted below. It has been updated based on several answers which gets me close enough for my needs. This generates files of the format: <strong>logfile_YYYY.MM.dd.log.seq</strong></p>
<pre><code><log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">

<param name="LevelMax" value="FATAL" />
</filter>
</appender>

</code></pre>
<p>One interesting note, setting</p>
<pre><code><staticLogFileName value="false"/>
</code></pre>
<p>to true causes the logger to not write any files.</p>

243,617 | <p>I have a Java based web-application and a new requirement to allow Users to place variables into text fields that are replaced when a document or other output is produced. How have others gone about this?</p>
<p>I was thinking of having a pre-defined set of variables such as :<br>
<code>@BOOKING_NUMBER@</code><br>
<code>@INVOICE_NUMBER@</code> </p>
<p>Then when a user enters some text they can specify a variable inline (select it from a modal or similar). For example:</p>
<p><em>"This is some text for Booking <code>@BOOKING_NUMBER@</code> that is needed by me"</em> </p>
<p>When producing some output (eg. PDF) that uses this text, I would do a regex and find all variables and replace them with the correct value: </p>
<p><em>"This is some text for Booking 10001 that is needed by me"</em> </p>
<p>My initial thought was something like Freemarker but I think that is too complex for my Users and would require them to know my DataModel (eww).</p>
<p>Thanks for reading!</p>
<p>D.</p>

243,696 | <p>MathWorks currently doesn't allow you to use <code>cout</code> from a mex file when the MATLAB desktop is open because they have redirected stdout. Their current workaround is providing a function, <a href="http://www.mathworks.com/support/tech-notes/1600/1605.html" rel="nofollow noreferrer">mexPrintf, that they request you use instead</a>. After googling around a bit, I think that it's possible to extend the <code>std::stringbuf</code> class to do what I need. Here's what I have so far. Is this robust enough, or are there other methods I need to overload or a better way to do this? (Looking for portability in a general UNIX environment and the ability to use <code>std::cout</code> as normal if this code is not linked against a mex executable)</p>
<pre><code>class mstream : public stringbuf {
public:
virtual streamsize xsputn(const char *s, std::streamsize n)
{
mexPrintf("*s",s,n);
return basic_streambuf<char, std::char_traits<char>>::xsputn(s,n);
}
};
mstream mout;
outbuf = cout.rdbuf(mout.rdbuf());

<p>I noticed that in some situations they used hex numbers, like in line 134:</p>
<pre><code>for (j = 1; val && j <= 0x80; j <<= 1, q++)
</code></pre>
<p>Now why would they use the 0x80? I am not that good with hex but I found an online hex to decimal and it gave me 128 for 0x80.</p>
<p>Also before line 134, on line 114 they have this:</p>
<pre><code>small_n = (n & 0xffff0000) == 0;
</code></pre>
<p>The hex to decimal gave me 4294901760 for that hex number.
So here in this line they are making a bit AND and comparing the result to 0??</p>
<p>Why not just use the number?
Can anyone please explain and please do give examples of other situations.</p>
<p>Also I have seen large lines of code where it's just hex numbers and never really understood why :(</p>

243,734 | <p>I am trying to compile a labview CIN using visual studio 2003.</p>
<p>I have followed the tutorial located <a href="http://zone.ni.com/devzone/cda/tut/p/id/3172" rel="nofollow noreferrer">here</a> to the letter, but am getting the following error:</p>
<blockquote>
<p>Project : error PRJ0019: A tool returned an error code from "Performing Custom Build Step"</p>
</blockquote>
<p>Does anyone know what is causing this? I tried this <a href="http://detritus.blogs.com/lycangeek/2006/03/building_cins_w.html" rel="nofollow noreferrer">link</a> found at an expert's exchange <a href="http://www.experts-exchange.com/Microsoft/Development/.NET/Visual_CPP/Q_23144843.html" rel="nofollow noreferrer">question</a> but it does not seem relevant.</p>
<p>Is there an easier way to build a CIN using visual studio?</p>

243,750 | <p>I've searched around a bit for similar questions, but other than running one command or perhaps a few command with items such as:</p>
<pre><code>ssh user@host -t sudo su -
</code></pre>
<p>However, what if I essentially need to run a script on (let's say) 15 servers at once. Is this doable in bash? In a perfect world I need to avoid installing applications if at all possible to pull this off. For argument's sake, let's just say that I need to do the following across 10 hosts:</p>
<ol>
<li>Deploy a new Tomcat container</li>
<li>Deploy an application in the container, and configure it</li>
<li>Configure an Apache vhost</li>
<li>Reload Apache</li>
</ol>
<p>I have a script that does all of that, but it relies on me logging into all the servers, pulling a script down from a repo, and then running it. If this isn't doable in bash, what alternatives do you suggest? Do I need a bigger hammer, such as Perl (Python might be preferred since I can guarantee Python is on all boxes in a RHEL environment thanks to yum/up2date)? If anyone can point to me to any useful information it'd be greatly appreciated, especially if it's doable in bash. I'll settle for Perl or Python, but I just don't know those as well (working on that). Thanks!</p>

243,782 | <p>I'm trying to select a column from a single table (no joins) and I need the count of the number of rows, ideally before I begin retrieving the rows. I have come to two approaches that provide the information I need.</p>
<p><strong>Approach 1:</strong></p>
<pre><code>SELECT COUNT( my_table.my_col ) AS row_count
FROM my_table
WHERE my_table.foo = 'bar'
</code></pre>
<p>Then</p>
<pre><code>SELECT my_table.my_col
FROM my_table
WHERE my_table.foo = 'bar'
</code></pre>
<p>Or <strong>Approach 2</strong></p>
<pre><code>SELECT my_table.my_col, ( SELECT COUNT ( my_table.my_col )
FROM my_table
WHERE my_table.foo = 'bar' ) AS row_count
FROM my_table
WHERE my_table.foo = 'bar'
</code></pre>
<p>I am doing this because my SQL driver (SQL Native Client 9.0) does not allow me to use SQLRowCount on a SELECT statement but I need to know the number of rows in my result in order to allocate an array before assigning information to it. The use of a dynamically allocated container is, unfortunately, not an option in this area of my program.</p>
<p>I am concerned that the following scenario might occur:</p>
<ul>
<li>SELECT for count occurs</li>
<li>Another instruction occurs, adding or removing a row</li>
<li>SELECT for data occurs and suddenly the array is the wrong size.<br>
-In the worse case, this will attempt to write data beyond the arrays limits and crash my program.</li>
</ul>
<p>Does Approach 2 prohibit this issue?</p>
<p>Also, Will one of the two approaches be faster? If so, which?</p>
<p>Finally, is there a better approach that I should consider (perhaps a way to instruct the driver to return the number of rows in a SELECT result using SQLRowCount?)</p>
<p>For those that asked, I am using Native C++ with the aforementioned SQL driver (provided by Microsoft.)</p>

243,790 | <p>I have this table in an Oracle DB which has a primary key defined on 3 of the data columns. I want to drop the primary key constraint to allow rows with duplicate data for those columns, and create a new column, 'id', to contain an auto-incrementing integer ID for these rows. I know how to create a sequence and trigger to add an auto-incrementing ID for new rows added to the table, but is it possible to write a PL/SQL statement to add unique IDs to all the rows that are already in the table?</p>

243,800 | <p><strong>The Situation</strong></p>
<p>I have an area of the screen that can be shown and hidden via JavaScript (something like "show/hide advanced search options"). Inside this area there are form elements (select, checkbox, etc). For users using assistive technology like a screen-reader (in this case JAWS), we need to link these form elements with a label or use the "title" attribute to describe the purpose of each element. I'm using the title attribute because there isn't enough space for a label, and the tooltip you get is nice for non-screen-reader users.</p>
<p>The code looks something like this:</p>
<pre><code><div id="placeholder" style="display:none;">
<select title="Month">
<option>January</option>
<option>February</option>
...
</select>
</div>
</code></pre>
<p><strong>The Problem</strong></p>
<p>Normally, JAWS will not read hidden elements... because well, they're hidden and it knows that. However, it seems as though if the element has a title set, JAWS reads it no matter what. If I remove the title, JAWS reads nothing, but obviously this is in-accessible markup.</p>
<p><strong>Possible Solutions</strong></p>
<p>My first thought was to use a hidden label instead of the title, like this:</p>
<pre><code><div id="placeholder" style="display:none;">
<label for="month" style="display:none">Month</label>
<select id="month">...</select>
</div>
</code></pre>
<p>This results in the exact same behavior, and now we lose the tool-tips for non-screen-reader users. Also we end up generating twice as much Html.</p>
<p>The second option is to still use a label, put position it off the screen. That way it will be read by the screen-reader, but won't be seen by the visual user:</p>
<pre><code><div id="placeholder" style="display:none;">
<label for="month" style="position:absolute;left:-5000px:width:1px;">Month</label>
<select id="month">...</select>
</div>
</code></pre>
<p>This actually works, but again we lose the tool-tip and still generate additional Html.</p>
<p>My third possible solution is to recursively travel through the DOM in JavaScript, removing the title when the area is hidden and adding it back when the area is shown. This also works... but is pretty ugly for obvious reasons and doesn't really scale well to a more general case.</p>
<p>Any other ideas anyone? Why is JAWS behaving this way?</p>

<p>I've asked the developer responsible and he said he used it because it was new (which doesn't seem like a particularly good reason to me), but I'm intrigued when I would want to use the method.</p>

243,900 | <p>I've seen some code where a <em>Class</em> is imported, instead of a namespace, making all the static members/methods of that class available. Is this a feature of VB? Or do other languages do this as well?</p>
<p>TestClass.vb</p>
<pre><code>public class TestClass
public shared function Somefunc() as Boolean
return true
end function
end class
</code></pre>
<p>MainClass.vb</p>
<pre><code>imports TestClass
public class MainClass
public sub Main()
Somefunc()
end sub
end class
</code></pre>
<p>These files are in the App_Code directory. Just curious, because I've never thought of doing this before, nor have I read about it anywhere. </p>

243,929 | <p>I have several arrays of arrays or arrays of dicts that I would like to store in my iPhone app. This lists are static and won't be modified by the app or users. Occasionally they may be displayed but more likely they'll be iterated over and compared to some input value. Would the best way to store these arrays be a CoreData/SQLite data store, in a header file, or something I'm not thinking of? I could see making a class that only has these arrays stored in them for access, but I'm not sure if that's the best route to take.</p>

243,945 | <p>From wikipedia: </p>
<blockquote>
<p>the cross product is a binary operation on two vectors in a <strong>three-dimensional</strong> Euclidean space that results in another vector which is perpendicular to the plane containing the two input vectors.</p>
</blockquote>
<p>Given that the definition is only defined in three (<a href="https://en.wikipedia.org/wiki/Seven-dimensional_cross_product#Consequences_of_the_defining_properties" rel="noreferrer">or seven, one and zero</a>) dimensions, how does one calculate the cross product of two 2d vectors?</p>
<p>I have seen two implementations. One returns a new vector (but only accepts a single vector), the other returns a scalar (but is a calculation between two vectors).</p>
<p>Implementation 1 (returns a scalar):</p>
<pre><code>float CrossProduct(const Vector2D & v1, const Vector2D & v2) const
{
return (v1.X*v2.Y) - (v1.Y*v2.X);
}
</code></pre>
<p>Implementation 2 (returns a vector):</p>
<pre><code>Vector2D CrossProduct(const Vector2D & v) const
{
return Vector2D(v.Y, -v.X);
}
</code></pre>
<p>Why the varying implementations? What would I use the scalar implementation for? What would I use the vector implementation for?</p>
<p>The reason I ask is because I'm writing a Vector2D class myself and don't know which method to use.</p>

243,956 | <p>I currently have a silverlight application which rotates through several graphs of live data. Each page has two user controls though: one for an info box at the top and another for the graph to display. I have tried to add a background image to the master page that they are displayed on so that the image is behind everything but as soon as they load, they overwrite the image with their blank canvas.</p>
<p>So far attempts to make the background of the user controls transparent have had no effect.</p>
<p>Any help would be greatly appreciated.</p>

243,967 | <p>Sometimes you need to skip execution of part of a method under certain non-critical error conditions. You can use <em>exceptions</em> for that, but exceptions generally are not recommended in normal application logic, only for abnormal situations.</p>
<p>So I do a trick like this:</p>
<pre><code>do
{
bool isGood = true;
.... some code
if(!isGood)
break;
.... some more code
if(!isGood)
break;
.... some more code
} while(false);
..... some other code, which has to be executed.
</code></pre>
<p>I use a "fake" loop which will run once, and I can abort it by <em>break</em> or <em>continue</em>.</p>
<p>Some of my colleagues did not like that, and they called it "bad practice". I personally find that approach pretty slick. But what do you think?</p>

<pre><code> public static void SetPermissions(string dir)

DirectorySecurity ds = info.GetAccessControl();
ds.AddAccessRule(new FileSystemAccessRule(@"BUILTIN\Users",
FileSystemRights.FullControl,

AccessControlType.Allow));
info.SetAccessControl(ds);
}

<p>However it's not working as I would expect it to.<br>
Even if I run the code as administrator it will not set the permissions.</p>
<p>The folder I am working with is located in C:\ProgramData\<my folder> and I can manually change the rights on it just fine.</p>
<p>Any one want to point me in the right direction.</p>

244,001 | <p>I know that cursors are frowned upon and I try to avoid their use as much as possible, but there may be some legitimate reasons to use them. I have one and I am trying to use a pair of cursors: one for the primary table and one for the secondary table. The primary table cursor iterates through the primary table in an outer loop. the secondary table cursor iterates through the secondary table in the inner loop.
The problem is, that the primary table cursor though apparently proceeding and saving the primary key column value [Fname] into a local variable @Fname, but it does not get the row for the corresponding foreign key column in the secondary table. For the secondary table it always returns the rows whose foreign key column value matches the primary key column value of the <strong>first row</strong> of the primary table. </p>
<p>Following is a very simplified example for what I want to do in the real stored procedure.
Names is the primary table</p>
<pre><code>SET NOCOUNT ON
DECLARE
@Fname varchar(50) -- to hold the fname column value from outer cursor loop
,@FK_Fname varchar(50) -- to hold the fname column value from inner cursor loop
,@score int
;
--prepare primary table to be iterated in the outer loop
DECLARE @Names AS Table (Fname varchar(50))
INSERT @Names
SELECT 'Jim' UNION
SELECT 'Bob' UNION
SELECT 'Sam' UNION
SELECT 'Jo'
--prepare secondary/detail table to be iterated in the inner loop
DECLARE @Scores AS Table (Fname varchar(50), Score int)
INSERT @Scores
SELECT 'Jo',1 UNION
SELECT 'Jo',5 UNION
SELECT 'Jim',4 UNION
SELECT 'Bob',10 UNION
SELECT 'Bob',15
--cursor to iterate on the primary table in the outer loop
DECLARE curNames CURSOR
FOR SELECT Fname FROM @Names
OPEN curNames
FETCH NEXT FROM curNames INTO @Fname
--cursor to iterate on the secondary table in the inner loop
DECLARE curScores CURSOR
FOR
SELECT FName,Score
FROM @Scores
WHERE Fname = @Fname
--*** NOTE: Using the primary table's column value @Fname from the outer loop
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'Outer loop @Fname = ' + @Fname
OPEN curScores
FETCH NEXT FROM curScores INTO @FK_Fname, @Score
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT ' FK_Fname=' + @FK_Fname + '. Score=' + STR(@Score)
FETCH NEXT FROM curScores INTO @FK_Fname, @Score
END
CLOSE curScores
FETCH NEXT FROM curNames INTO @Fname
END
DEALLOCATE curScores
CLOSE curNames
DEALLOCATE curNames
</code></pre>
<p>Here is what I get for the result. Please note that for the outer loop it DOES show the up-to-date Fname, but when that Fname is used as @Fname to fetch the relevant row from the secondary table for the succeeding iterations, it still get the rows that match the first row (Bob) of the primary table.</p>
<pre><code>Outer loop @Fname = Bob
FK_Fname=Bob. Score=10
FK_Fname=Bob. Score=15
Outer loop @Fname = Jim
FK_Fname=Bob. Score=10
FK_Fname=Bob. Score=15
Outer loop @Fname = Jo
FK_Fname=Bob. Score=10
FK_Fname=Bob. Score=15
Outer loop @Fname = Sam
FK_Fname=Bob. Score=10
FK_Fname=Bob. Score=15
</code></pre>
<p>Please let me know what am I do wrong.
Thanks in advance!</p>

244,009 | <p>In my Rails controller, I'm creating multiple instances of the same model class. I want to add some RSpec expectations so I can test that it is creating the correct number with the correct parameters. So, here's what I have in my spec:</p>
<pre>
Bandmate.should_receive(:create).with(:band_id => @band.id, :user_id => @user.id, :position_id => 1, :is_leader => true)
Bandmate.should_receive(:create).with(:band_id => @band.id, :user_id => "2222", :position_id => 2)
Bandmate.should_receive(:create).with(:band_id => @band.id, :user_id => "3333", :position_id => 3)
Bandmate.should_receive(:create).with(:band_id => @band.id, :user_id => "4444", :position_id => 4)
</pre>
<p>This is causing problems because it seems that the Bandmate class can only have 1 "should_receive" expectation set on it. So, when I run the example, I get the following error:</p>
<pre>
Spec::Mocks::MockExpectationError in 'BandsController should create all the bandmates when created'
Mock 'Class' expected :create with ({:band_id=>1014, :user_id=>999, :position_id=>1, :is_leader=>true}) but received it with ({:band_id=>1014, :user_id=>"2222", :position_id=>"2"})
</pre>
<p>Those are the correct parameters for the second call to create, but RSpec is testing against the wrong parameters.</p>
<p>Does anyone know how I can set up my should_receive expectations to allow multiple different calls?</p>

244,018 | <p>I'm using Flex 3 in the UI of a Windows app (Flash player as an embedded ActiveX control), and passing data between them with ExternalInterface (primarily into the Flex app, as opposed to out). I'm finding, though, that the performance is pretty awful, particularly with larger (i.e., custom) objects; the more EI calls we make, and the larger the custom objects as pass in, the harder things seem to drop off performance-wise.</p>
<p>I'm assuming there's a good deal of overhead in serializing these objects, so I'm wondering, are there any best practices out there for using ExternalInterface in this particular way? There doesn't seem to be much out there in terms of documentation on this subject yet.</p>
<p>Is it better, say, to pass a large block of XML into the player control as a string, and parse it with Flex, than to pass it as a custom object, as a rule? How should Flex apps requiring a relatively tight integration with their host apps best use ExternalInterface without sacrificing performance? Is EI performance an issue Adobe is addressing? Any implementation differences between players 9 and 10? What kinds of things should we avoid to get the most out of this feature?</p>
<p>Thanks in advance!</p>

</blockquote>
<p>From the front end, the time is selected using the "TimeEdit" control, with the up and down arrows. The table in SQL Server has the fields set as smalldatetime. I only need to store the time. I use the following to return data to the app</p>
<p>select id,CONVERT(CHAR(5),timeFrom,8)as timeFrom,CONVERT(CHAR(5),timeTo,8)as timeTo
FROM dbo.Availability
where id = @id
and dayName = @weekday</p>
<p>How do I pass time only to the table?</p>
<p>Edit ~ Solution
As per Euardo and Chris, my solution was to pass a datetime string instead of a time only string. I formatted my result as per <a href="http://msdn.microsoft.com/en-us/library/az4se3k1(VS.71).aspx" rel="nofollow noreferrer">Time Format</a> using "g".</p>

244,087 | <p>What are some things I can do to improve query performance of an oracle query without creating indexes?</p>
<p>Here is the query I'm trying to run faster:</p>
<pre><code>SELECT c.ClaimNumber, a.ItemDate, c.DTN, b.FilePath
FROM items a,
itempages b,
keygroupdata c
WHERE a.ItemType IN (112,115,189,241)
AND a.ItemNum = b.ItemNum
AND b.ItemNum = c.ItemNum
ORDER BY a.DateStored DESC
</code></pre>
<p>None of these columns are indexed and each of the tables contains millions of records. Needless to say, it takes over 3 and half minutes for the query to execute. This is a third party database in a production environment and I'm not allowed to create any indexes so any performance improvements would have to be made to the query itself.</p>
<p>Thanks!</p>

<pre><code>File error: data may have been lost.

<p>Even stranger is the fact that, despite the error, the file seems fine. Any data I happen to be writing is there.</p>
<p>Any ideas on how to get rid of this error?</p>

<p>I've modified the code sample to better illustrate the problem. I don't think the first sample was a legit test.</p>

244,113 | <p>I'm working on a stored procedure in SQL Server 2000 with a temp table defined like this:</p>
<pre>CREATE TABLE #MapTable (Category varchar(40), Code char(5))</pre>
<p>After creating the table I want to insert some standard records (which will then be supplemented dynamically in the procedure). Each category (about 10) will have several codes (typically 3-5), and I'd like to express the insert operation for each category in one statement. </p>
<p>Any idea how to do that? </p>
<p>The best idea I've had so far is to keep a real table in the db as a template, but I'd really like to avoid that if possible. The database where this will live is a snapshot of a mainframe system, such that the entire database is blown away every night and re-created in a batch process- stored procedures are re-loaded from source control at the end of the process.</p>
<p>The issue I'm trying to solve isn't so much keeping it to one statement as it is trying to avoid re-typing the category name over and over.</p>

244,114 | <p>I'm developing a poker game in C#. At the moment I'm trying to get the players hand score using <code>RegEx</code>. I search the string (composed of the cards suit and number) and look for suits or numbers to match the <code>RegEx</code>. If i get 2 matches then the player has a pair, 3 matches he has 3 of a kind. </p>
<p>I have 3 classes at the moment, a Card class (with number and suit), a Deck class (that contains 52 Cards) and a Hand class that gets five cards from the shuffled deck.</p>
<p>Deck class has a <code>shuffleDeck()</code>;
Hand class has the functions to calculate the score (is in these functions that I am using RegEx).</p>
<p>I generate the string on which I use <code>RegEx</code> by adding the 5 suits and numbers that the hand has.</p>
<p>Is this a good idea or should I do it another way, if so, how?</p>
<p>Thank you for your help</p>
<p>PS. I am one of the unexperienced programmers that want to use a newly learned tool for everything</p>

244,246 | <p>I want to create an alias for a class name. The following syntax would be perfect:</p>
<pre><code>public class LongClassNameOrOneThatContainsVersionsOrDomainSpecificName
{
...
}
public class MyName = LongClassNameOrOneThatContainsVersionOrDomainSpecificName;
</code></pre>
<p>but it won't compile.</p>
<hr />
<h2>Example</h2>
<p><strong>Note</strong> This example is provided for convenience only. Don't try to solve this particular problem by suggesting changing the design of the entire system. The presence, or lack, of this example doesn't change the original question.</p>
<p>Some existing code depends on the presence of a static class:</p>
<pre><code>public static class ColorScheme
{
...
}
</code></pre>
<p>This color scheme is the Outlook 2003 color scheme. i want to introduce an Outlook 2007 color scheme, while retaining the Outlook 2003 color scheme:</p>
<pre><code>public static class Outlook2003ColorScheme
{
...
}
public static class Outlook2007ColorScheme
{
...
}
</code></pre>
<p>But i'm still faced with the fact that the code depends on the presence of a static class called <code>ColorScheme</code>. My first thought was to create a <code>ColorScheme</code> class that I will inherit from either <code>Outlook2003</code> or <code>Outlook2007</code>:</p>
<pre><code>public static class ColorScheme : Outlook2007ColorScheme
{
}
</code></pre>
<p>but you cannot inherit from a static class.</p>
<p>My next thought was to create the static <code>ColorScheme</code> class, but make <code>Outlook2003ColorScheme</code> and <code>Outlook2007ColorScheme</code> classes non-static. Then a static variable in the static <code>ColorScheme</code> class can point to either "true" color scheme:</p>
<pre><code>public static class ColorScheme
{
private static CustomColorScheme = new Outlook2007ColorScheme();
...
}
private class CustomColorScheme
{
...
}
private class Outlook2008ColorScheme : CustomColorScheme
{
...
}
private class Outlook2003ColorScheme : CustomColorScheme
{
...
}
</code></pre>
<p>but that would require me to convert a class composed entirly of readonly static Colors into overridable properties, and then my <code>ColorScheme</code> class would need to have the 30 different property getters thunk down into the contained object.</p>
<p>That's just too much typing.</p>
<p>So my next thought was to alias the class:</p>
<pre><code>public static ColorScheme = Outlook2007ColorScheme;
</code></pre>
<p>But that doesn't compile.</p>
<p>How can I alias a static class into another name?</p>
<hr />
<p><strong>Update:</strong> Can someone please add the answer <em>"You cannot do this in C#"</em>, so I can mark that as the accepted answer. Anyone else wanting the answer to the same question will find this question, the accepted answer, and a number of workarounds that might, or might not, be useful.</p>
<p>I just want to close this question out.</p>

244,252 | <p>I've been looking (without great luck) for the perfect reference card with all the basic sorting algos in C (or maybe in pseudo code). Wikipedia is a terrific source of info but this time I'm looking for something definitely more portable (pocket size if possible) and of course printable. Any suggestion would be much appreciated!</p>

244,264 | <p>I am currently trying to learn all new features of C#3.0. I have found a very nice collection of <a href="http://msdn.microsoft.com/en-us/vcsharp/aa336746.aspx" rel="nofollow noreferrer">sample to practice LINQ</a> but I can't find something similar for Lambda.</p>
<p>Do you have a place that I could practice Lambda function?</p>
<h2>Update</h2>
<p>LINQpad is great to learn Linq (thx for the one who suggest) and use a little bit Lambda in some expression. But I would be interesting in more specific exercise for Lambda.</p>

244,276 | <p>A website I'm working on (using AS2 because it's oldschool) has a larger index .swf file that loads sub-swfs using <code>loadMovie("foo1.swf", placeToShowSwf)</code>. There's <code>foo1.swf</code> through 4, which is silly because the only thing that's different between them is a single number in the address of an xml file that tells it what content to load. So I want to reduce this to one file, with a simple function that the index file calls to load the xml file, as seen here.</p>
<pre><code>function setFooNum(i:Number) {
fooNum = i;
//my_xml = new XML(); edit: this line has since been removed and is kept for historical purposes
my_xml.load("foo"+fooNum+".xml");
};
</code></pre>
<p>However, for some reason, the xml file won't load. It loads properly outside the function, but that doesn't do me much good. It changes fooNum properly, but that doesn't do me any good if the wrong xml file is already loading. As far as I can tell, the code behaves as though the <code>my_xml.load("foo"+fooNum+".xml")</code> isn't there at all.</p>
<p>Is this some sort of security measure I don't know about, and is there any way around it?</p>
<p><strong><em>EDIT</em></strong>
As several people pointed out, the <code>my_xml = new XML()</code> line was the culprit. Unfortunately, I'm now getting a new and exciting error. When <code>setFooNum(i)</code> is called immediately after the <code>loadMove()</code> in the index file, a <code>trace(fooNum)</code> inside the <code>setFooNum()</code> function prints that fooNum is set correctly, but a <code>trace(fooNum)</code> inside the <code>onLoad()</code> (which returns a success despite loading apparently nothing, btw) shows that fooNum is undefined! Also, I made a button in the index swf that calls <code>setFooNum(3)</code> (for debugging purposes), which for some reason makes it work fine. So waiting a few seconds for the file to load seems to solve the problem, but that's an incredibly ugly solution. </p>
<p>So how do I wait until everything is completely loaded before calling <code>setFooNum()</code>? </p>

244,280 | <p>I'm trying to implement a unit test for a function in a project that doesn't have unit tests and this function requires a System.Web.Caching.Cache object as a parameter. I've been trying to create this object by using code such as...</p>
<pre><code>System.Web.Caching.Cache cache = new System.Web.Caching.Cache();
cache.Add(...);
</code></pre>
<p>...and then passing the 'cache' in as a parameter but the Add() function is causing a NullReferenceException. My best guess so far is that I can't create this cache object in a unit test and need to retrieve it from the HttpContext.Current.Cache which I obviously don't have access to in a unit test.</p>
<p>How do you unit test a function that requires a System.Web.Caching.Cache object as a parameter?</p>

244,285 | <p>I've got to get a quick and dirty configuration editor up and running. The flow goes something like this:</p>
<p>configuration (POCOs on server) are serialized to XML.<br>
The XML is well formed at this point. The configuration is sent to the web server in XElements.<br>
On the web server, the XML (Yes, ALL OF IT) is dumped into a textarea for editing.<br>
The user edits the XML directly in the webpage and clicks Submit.<br>
In the response, I retrieve the altered text of the XML configuration. At this point, ALL escapes have been reverted by the process of displaying them in a webpage.<br>
I attempt to load the string into an XML object (XmlElement, XElement, whatever). KABOOM.</p>
<p>The problem is that serialization escapes attribute strings, but this is lost in translation along the way. </p>
<p>For example, let's say I have an object that has a regex. Here's the configuration as it comes to the web server:</p>
<pre><code><Configuration>
<Validator Expression="[^&lt;]" />
</Configuration>
</code></pre>
<p>So, I put this into a textarea, where it looks like this to the user:</p>
<pre><code><Configuration>
<Validator Expression="[^<]" />
</Configuration>
</code></pre>
<p>So the user makes a slight modification and submits the changes back. On the web server, the response string looks like:</p>
<pre><code><Configuration>
<Validator Expression="[^<]" />
<Validator Expression="[^&]" />
</Configuration>
</code></pre>
<p>So, the user added another validator thingie, and now BOTH have attributes with illegal characters. If I try to load this into any XML object, it throws an exception because < and & are not valid within a text string. I CANNOT CANNOT CANNOT CANNOT use any kind of encoding function, as it encodes the entire bloody thing:</p>
<p>var result = Server.HttpEncode(editedConfig);</p>
<p>results in </p>
<pre><code>&lt;Configuration&gt;
&lt;Validator Expression="[^&lt;]" /&gt;
&lt;Validator Expression="[^&amp;]" /&gt;
&lt;/Configuration&gt;
</code></pre>
<p>This is NOT valid XML. If I try to load this into an XML element of any kind I will be hit by a falling anvil. I don't like falling anvils. </p>
<p>SO, the question remains... Is the ONLY way I can get this string XML ready for parsing into an XML object is by using regex replaces? Is there any way to "turn off constraints" when I load? How do you get around this???</p>
<hr>
<p>One last response and then wiki-izing this, as I don't think there is a valid answer.</p>
<p>The XML I place in the textarea IS valid, escaped XML. The process of 1) putting it in the text area 2) sending it to the client 3) displaying it to the client 4) submitting the form it's in 5) sending it back to the server and 6) retrieving the value from the form REMOVES ANY AND ALL ESCAPES. </p>
<p>Let me say this again: I'M not un-escaping ANYTHING. Just displaying it in the browser does this!</p>
<p>Things to mull over: Is there a way to prevent this un-escaping from happening in the first place? Is there a way to take almost-valid XML and "clean" it in a safe manner?</p>
<hr>
<p>This question now has a bounty on it. To collect the bounty, you demonstrate how to edit VALID XML in a browser window WITHOUT a 3rd party/open source tool that doesn't require me to use regex to escape attribute values manually, that doesn't require users to escape their attributes, and that doesn't fail when roundtripping (&amp;amp;amp;amp;etc;)</p>

244,329 | <p>Something happened that I'm not sure should be possible. Obviously it is, because I've seen it, but I need to find the root cause & I was hoping you all could help.</p>
<p>We have a system that looks up latitude & longitude for a zipcode. Rather than access it every time, we cache the results in a cheap in-memory HashTable cache, since the lat & long of a zip code tend to change less often than we release.</p>
<p>Anyway, the hash is surrounded by a class that has a "get" and "add" method that are both synchronized. We access this class as a singleton.</p>
<p>I'm not claiming this is the best setup, but it's where we're at. (I plan to change to wrap the Map in a Collections.synchronizedMap() call ASAP.)</p>
<p>We use this cache in a multi-threaded environment, where we thread 2 calls for 2 zips (so we can calculate the distance between the two). These sometimes happen at very nearly the same time, so its very possible that both calls access the map at the same time.</p>
<p>Just recently we had an incident where two different zip codes returned the same value. Assuming that the initial values were actually different, is there any way that writing the values into the Map would cause the same value to be written for two different keys? Or, is there any way that 2 "gets" could cross wires and accidentally return the same value?</p>
<p>The only other explanation I have is that the initial data was corrupt (wrong values), but it seems very unlikely.</p>
<p>Any ideas would be appreciated.
Thanks,
Peter</p>

244,340 | <p>I am getting a DC for a window handle of an object in another program using win32gui.GetDC which returns an int/long. I need to blit this DC into a memory DC in python. The only thing I can't figure out how to do is get a wxDC derived object from the int/long that win32gui returns. None of the wxDC objects allow me to pass an actual DC handle to them from what I can tell. This of course keeps me from doing my blit. Is there any way to do this?</p>

244,345 | <p>I was watching Rob Connerys webcasts on the MVCStoreFront App, and I noticed he was unit testing even the most mundane things, things like:</p>
<pre><code>public Decimal DiscountPrice
{
get
{
return this.Price - this.Discount;
}
}
</code></pre>
<p>Would have a test like:</p>
<pre><code>[TestMethod]
public void Test_DiscountPrice
{
Product p = new Product();
p.Price = 100;
p.Discount = 20;
Assert.IsEqual(p.DiscountPrice,80);
}
</code></pre>
<p>While, I am all for unit testing, I sometimes wonder if this form of test first development is really beneficial, for example, in a real process, you have 3-4 layers above your code (Business Request, Requirements Document, Architecture Document), where the actual defined business rule (Discount Price is Price - Discount) could be misdefined.</p>
<p>If that's the situation, your unit test means nothing to you.</p>
<p>Additionally, your unit test is another point of failure:</p>
<pre><code>[TestMethod]
public void Test_DiscountPrice
{
Product p = new Product();
p.Price = 100;
p.Discount = 20;
Assert.IsEqual(p.DiscountPrice,90);
}
</code></pre>
<p>Now the test is flawed. Obviously in a simple test, it's no big deal, but say we were testing a complicated business rule. What do we gain here?</p>
<p>Fast forward two years into the application's life, when maintenance developers are maintaining it. Now the business changes its rule, and the test breaks again, some rookie developer then fixes the test incorrectly...we now have another point of failure.</p>
<p>All I see is more possible points of failure, with no real beneficial return, if the discount price is wrong, the test team will still find the issue, how did unit testing save any work?</p>
<p>What am I missing here? Please teach me to love TDD, as I'm having a hard time accepting it as useful so far. I want too, because I want to stay progressive, but it just doesn't make sense to me.</p>
<p>EDIT: A couple people keep mentioned that testing helps enforce the spec. It has been my experience that the spec has been wrong as well, more often than not, but maybe I'm doomed to work in an organization where the specs are written by people who shouldn't be writing specs.</p>

<pre>$("a").toggle(function() { /*function A*/ }, function() { /*function B*/ });</pre>
<p>Inside <code>function A</code> a form is displayed. If the user successfully completes the form, the form is hidden again (returning to it's original state).</p>
<p>Inside <code>function B</code> the same form is hidden.</p>
<p>The theory behind this is that the user can choose to display the form and fill it out, or they can click again and have the form go back into hiding. </p>
<p>Now my question is this: currently, if the user fills out the form successfully--and it goes into hiding--the user would have to click on the link <strong><em>twice</em></strong> before returning to the toggle state that displays the form.</p>
<p>Is there anyway to programmatically reset the toggle switch to its initial state?</p>

<p>So what's the best way you've come up with or seen to refactor the dreaded While (True) loop?</p>

244,452 | <h1>My situation</h1>
<ul>
<li>Input: a set of rectangles </li>
<li>each rect is comprised of 4 doubles like this: (x0,y0,x1,y1)</li>
<li>they are not "rotated" at any angle, all they are "normal" rectangles that go "up/down" and "left/right" with respect to the screen</li>
<li>they are randomly placed - they may be touching at the edges, overlapping , or not have any contact</li>
<li>I will have several hundred rectangles</li>
<li>this is implemented in C#</li>
</ul>
<h1>I need to find</h1>
<ul>
<li>The area that is formed by their overlap - all the area in the canvas that more than one rectangle "covers" (for example with two rectangles, it would be the intersection)</li>
<li>I don't need the geometry of the overlap - just the area (example: 4 sq inches)</li>
<li>Overlaps shouldn't be counted multiple times - so for example imagine 3 rects that have the same size and position - they are right on top of each other - this area should be counted once (not three times)</li>
</ul>
<h1>Example</h1>
<ul>
<li>The image below contains thre rectangles: A,B,C</li>
<li>A and B overlap (as indicated by dashes)</li>
<li>B and C overlap (as indicated by dashes)</li>
<li>What I am looking for is the area where the dashes are shown</li>
</ul>

244,482 | <p>Developing a heavily XML-based Java-application, I recently encountered an interesting problem on Ubuntu Linux.</p>
<p>My application, using the <a href="http://jpf.sourceforge.net/" rel="noreferrer">Java Plugin Framework</a>, appears unable to convert a <a href="http://www.dom4j.org/" rel="noreferrer">dom4j</a>-created XML document to <a href="http://xmlgraphics.apache.org/batik/" rel="noreferrer">Batik's</a> implementation of the SVG specification.</p>
<p>On the console, I learn that an error occurs:</p>
<pre>
Exception in thread "AWT-EventQueue-0" java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.apache.batik.dom.svg.SVGOMDocument.createAttribute(Ljava/lang/String;)Lorg/w3c/dom/Attr;" the class loader (instance of org/java/plugin/standard/StandardPluginClassLoader) of the current class, org/apache/batik/dom/svg/SVGOMDocument, and the class loader (instance of <bootloader>) for interface org/w3c/dom/Document have different Class objects for the type org/w3c/dom/Attr used in the signature
at org.apache.batik.dom.svg.SVGDOMImplementation.createDocument(SVGDOMImplementation.java:149)
at org.dom4j.io.DOMWriter.createDomDocument(DOMWriter.java:361)
at org.dom4j.io.DOMWriter.write(DOMWriter.java:138)
</pre>
<p>I figure that the problem is caused by a conflict between the original classloader from the JVM and the classloader deployed by the plugin framework.</p>
<p>To my knowledge, it's not possible to specify a classloader for the framework to use. It might be possible to hack it, but I would prefer a less aggressive approach to solving this problem, since (for whatever reason) it only occurs on Linux systems.</p>
<p>Has one of you encountered such a problem and has any idea how to fix it or at least get to the core of the issue?</p>

244,489 | <p>I have a managed dll that calls into a native library. This native library generally returns IntPtrs. These can be passed in to other methods in the native library to do things, or to tell the library to free the instance associated with the IntPtr. But only some of the instances need to freed in this way, others are managed by the library. The problem is that the documentation is not always clear about which instances must be freed and which must not.</p>
<p>What I want to know is if there is a way that I can tell if my code has kept references to any of the pointers which must be freed, and so is causing memory to leak?</p>

244,492 | <p>Is there something like a panel that I can use in a MFC application. This is to overlay the default window in MFC (a dialog application). Then to paint the panel black and paint some random stuff on top of it. Something like a view port.</p>
<p>is there a better option than this to achieve the same effect ?</p>

244,493 | <p>I have a certain POJO which needs to be persisted on a database, current design specifies its field as a single string column, and adding additional fields to the table is not an option.</p>
<p>Meaning, the objects need to be serialized in some way. So just for the basic implementation I went and designed my own serialized form of the object which meant concatenating all it's fields into one nice string, separated by a delimiter I chose. But this is rather ugly, and can cause problems, say if one of the fields contains my delimiter.</p>
<p>So I tried basic Java serialization, but from a basic test I conducted, this somehow becomes a very costly operation (building a ByteArrayOutputStream, an ObjectOutputStream, and so on, same for the deserialization).</p>
<p>So what are my options? What is the preferred way for serializing objects to go on a database?</p>
<p><strong>Edit:</strong> this is going to be a very common operation in my project, so overhead must be kept to a minimum, and performance is crucial. Also, third-party solutions are nice, but irrelevant (and usually generate overhead which I am trying to avoid)</p>

244,506 | <p>Given a list of urls, I would like to check that each url:</p>
<ul>
<li>Returns a 200 OK status code</li>
<li>Returns a response within X amount of time</li>
</ul>
<p>The end goal is a system that is capable of flagging urls as potentially broken so that an administrator can review them.</p>
<p>The script will be written in PHP and will most likely run on a daily basis via cron.</p>
<p>The script will be processing approximately 1000 urls at a go.</p>
<p>Question has two parts:</p>
<ul>
<li>Are there any bigtime gotchas with an operation like this, what issues have you run into?</li>
<li>What is the best method for checking the status of a url in PHP considering both accuracy and performance?</li>
</ul>

244,509 | <p>I'm planning to make a very simple program using php and mySQL. The main page will take information and make a new row in the database with that information. However, I need a number to put in for the primary key. Unfortunately, I have no idea about the normal way to determine what umber to use. Preferably, if I delete a row, that row's key won't ever be reused.</p>
<p>A preliminary search has turned up the AUTOINCREMENT keyword in mySQL. However, I'd still like to know if that will work for what I want and what the common solution to this issue is.</p>

244,522 | <p>I am writing a web application that will run in kiosk mode on a touch screen. I am currently only targeting it for running on Firefox 3. A few of the use cases I have need to visit external sites. I wish to do so with an embedded browser, which I'm tackling with the help of an <code><iframe></code>. I need back/forward buttons for the embedded home page. </p>
<p>I've managed to access the history object of the iframe with</p>
<pre><code>var w = document.getElementById('embeddedBrowser').contentWindow;
w.history.back();
</code></pre>
<p>The <code>history</code> of the embedded window is the same as that of the parent window. Therefore for a newly loaded <code><iframe></code>, this call will go back to the previous page of the system.</p>
<p>Is there any way to avoid this or a more correct way of solving this?</p>
