239,136 | <p>Using PHP, what's the fastest way to convert a string like this: <code>"123"</code> to an integer?</p>
<p>Why is that particular method the fastest? What happens if it gets unexpected input, such as <code>"hello"</code> or an array?</p>

239,171 | <p>I have sets of 5, 6 and 7 digit numbers. I need them to be displayed in the 000/000/000 format. So for example: </p>
<p>12345 would be displayed as 000/012/345 </p>
<p>and </p>
<p>9876543 would be displayed as 009/876/543</p>
<p>I know how to do this in a messy way, involving a series of if/else statements, and strlen functions, but there has to be a cleaner way involving regex that Im not seeing.</p>

<pre><code>
// i'm receiving a string containing : id operation arguments
data = read(socket);
tokens = tokenize(data," "); // tokenize the string based on spaces
if(tokens[0] == "A") {
if(tokens[1] == "some_operation") {
// here goes code for some_operation , will use the remaining tokens as arguments for function calls
}
else if(tokens[1] == "some_other_operation") {
// here goes code for some_other_operation , will use the remaining tokens
}
...
else {
// unknown operation
}
}
else if(tokens[0] == "B") {
if(tokens[1] == "some_operation_for_B") {
// do some operation for B
}
else if(tokens[1] == "yet_another_operation") {
// do yet_another_operation for B
}
...
else {
// unknown operation
}
}
</code></pre>
<p>I hope you get the point . The thing is I have a large number of <strong>id's</strong> and each has it's own <strong>operations</strong> , and I think it's kinda ugly to have 10 screens of code containing a lot of <strong>if's</strong> and <strong>else if's</strong>.</p>

However, the designer can't edit the subclass unless it can create an instance of the parent class.

<p>Is there a way to mark the methods so that they have to be implemented by subclasses, without marking them as abstract?</p>

239,463 | <p>I have an application that behaves oddly, and just to verify, I'd like to see which security zone it is currently running under.</p>
<p>I've found the System.Security.SecurityZone enum, but can't seem to find anything that will return which of these I'm running under.</p>
<p>Does anyone have any tips?</p>
<p>Basically I want to find out if my application is running in MyComputer, Intranet, Internet, Untrusted, Trusted, etc.</p>

239,465 | <p>I have a setup project for a .NET Service Application which uses a .NET component which exposes a COM interface (COM callable wrapper / CCW).
To get the component working on a target machine, it has to be registered with</p>
<blockquote>
<p>regasm.exe /tlb /codebase component.dll</p>
</blockquote>
<p>The /tlb switch to generate the typelib is mandatory in this case, otherwise I can't create objects from that assembly.</p>
<p>The question is, how can I configure my Visual Studio 2008 Setup-Project to register this assembly with a call to regasm /tlb ?</p>

239,486 | <p>I want to convert an XML document containing many elements within a node (around 150) into another XML document with a slightly different schema but mostly with the same element names. Now do I have to manually map each element/node between the 2 documents. For that I will have to hardcode 150 lines of mapping and element names. Something like this: </p>
<pre><code>XElement newOrder = new XElement("Order");
newOrder.Add(new XElement("OrderId", (string)oldOrder.Element("OrderId")),
newOrder.Add(new XElement("OrderName", (string)oldOrder.Element("OrderName")),
...............
...............
...............and so on
</code></pre>
<p>The newOrder document may contain additional nodes which will be set to null if nothing is found for them in the oldOrder. So do I have any other choice than to hardcode 150 element names like orderId, orderName and so on... Or is there some better more maintainable way?</p>

239,556 | <p>We are replacing the exception handling system in our app in order to conform to Vista certification, but the problem is how to force certain exceptions to be thrown, so that we can check the response.</p>
<p>Unfortunately the whole app was written without taking into consideration proper layering, abstraction or isolation principles, and within the timeframe introducing mocking and unit testing is out of the question :(</p>
<p>My idea is to introduce code which will throw a particular exception, either through a compiler directive or by respecting a value in the config file. We can then just run the app as normal and manually check how the exception is handled.</p>
<p>Just thought I'd put it out there and see if the SO community can think of anything better!</p>

239,588 | <p>I have a C++ STL set with a custom ordering defined.</p>
<p>The idea was that when items get added to the set, they're naturally ordered as I want them.</p>
<p>However, what I've just realised is that the ordering predicate can change as time goes by.</p>
<p>Presumably, the items in the set will then no longer be in order.</p>
<p>So two questions really:</p>
<ol>
<li><p>Is it harmful that the items would then be out of order? Am I right in saying that the worst that can happen is that new entries may get put into the wrong place (which actually I can live with). Or, could this cause crashes, lost entries etc?</p></li>
<li><p>Is there a way to "refresh" the ordering of the set? You can't seem to use std::sort() on a set. The best I can come up with is dumping out the contents to a temp container and re-add them.</p></li>
</ol>
<p>Any ideas?</p>
<p>Thanks, </p>

239,622 | <p>We have an x-files problem with our .NET application. Or, rather, hybrid Win32 and .NET application.</p>
<p>When it attempts to communicate with Oracle, it just dies. Vanishes. Goes to the big black void in the sky. No event log message, no exception, no nothing.</p>
<p>If we simply ask the application to talk to a MS SQL Server instead, which has the effect of replacing the usage of OracleConnection and related classes with SqlConnection and related classes, it works as expected.</p>
<p>Today we had a breakthrough.</p>
<p>For some reason, a customer had figured out that by placing all the application files in a directory on his desktop, it worked as expected with Oracle as well. Moving the directory down to the root of the drive, or in C:\Temp or, well, around a bit, made the crash reappear.</p>
<p>Basically it was 100% reproducable that the application worked if run from directory on desktop, and failed if run from directory in root.</p>
<p>Today we figured out that the difference that counted was wether there was a space in the directory name or not.</p>
<p>So, these directories would work:</p>
<pre><code>C:\Program Files\AppDir\Executable.exe
C:\Temp Lemp\AppDir\Executable.exe
C:\Documents and Settings\someuser\Desktop\AppDir\Executable.exe
</code></pre>
<p>whereas these would not:</p>
<pre><code>C:\CompanyName\AppDir\Executable.exe
C:\Programfiler\AppDir\Executable.exe <-- Program Files in norwegian
C:\Temp\AppDir\Executable.exe
</code></pre>
<p>I'm hoping someone reading this has seen similar behavior and have a "aha, you need to twiddle the frob on the oracle glitz driver configuration" or similar.</p>
<p>Anyone?</p>
<hr>
<p><strong>Followup #1:</strong> Ok, I've processed the procmon output now, both files from when I hit the button that attempts to open the window that triggers the cascade failure, and I've noticed that they keep track mostly, there's some smallish differences near the top of both files, and they they keep track a long way down.</p>
<p>However, when one run fails, the other keeps going and the next few lines of the log output are these:</p>
<pre><code>ReadFile C:\oracle\product\10.2.0\db_1\BIN\orageneric10.dll SUCCESS Offset: 274 432, Length: 32 768, I/O Flags: Non-cached, Paging I/O, Synchronous Paging I/O
ReadFile C:\oracle\product\10.2.0\db_1\BIN\orageneric10.dll SUCCESS Offset: 233 472, Length: 32 768, I/O Flags: Non-cached, Paging I/O, Synchronous Paging I/O
</code></pre>
<p>After this, the working run continues to execute, and the other touches the mscorwks.dll files a few times before threads close down and the app closes. Thus, the failed run does not touch the above files.</p>
<hr>
<p><strong>Followup #2:</strong> Figured I'd try to upgrade the oracle client drivers, but 10.2.0.1 is apparently the highest version available for Windows 2003 server and XP clients.</p>
<hr>
<p><strong>Followup #3:</strong> Well, we've ended up with a black-box solution. Basically we found that the problem is somewhere related to <a href="http://www.devexpress.com/Products/NET/ORM/" rel="nofollow noreferrer">XPO</a> and Oracle. XPO has a system-table it manages, called XPObjectType, with three columns: Oid, TypeName and AssemblyName. Due to how Oracle is configured in the databases we talk to, the column names were OID, TYPENAME and ASSEMBLYNAME. This would ordinarily not be a problem, except that XPO talks to the schema information directly and checks if the table is there with the right column names, and XPO doesn't handle case differences so it sees a XPObjectType table with three unknown columns and none of those it expects.</p>
<p>Exactly what XPO does now I don't really know, but if I dropped this table, and recreated it with the right case, using double quotes around all the column names to get the case right, the problem doesn't crop up.</p>
<p>Exactly where the space in the folder name comes into this, I still have no idea, but this problem had two tiers:</p>
<ol>
<li>Stop the application from crashing at our customers, short-term solution</li>
<li>Fix the bug, long-term solution</li>
</ol>
<p>Right now tier 1 is solved, tier 2 will be put back into the queue for now and prioritized. We're facing some bigger changes to our data tier anyway so this might not be a problem we need to solve, at least if all our Oracle-customers verify that the table-fix actually gets rid of the problem.</p>
<p>I'll accept the answer by <a href="https://stackoverflow.com/users/24995/dave-markle">Dave Markle</a> since though Process Monitor (the big brother of File Monitor) didn't actually pinpoint the problem, I was able to use it to determine that after my breakpoint in user-code where XPO had built up the query for this table, no I/O happened until all the entries for the application closing down was logged, which led me to believe it was this table that was the culprit, or at least influenced the problem somehow.</p>
<p>If I manage to get to the real cause of this, I'll update the post.</p>

239,645 | <p>I have an abstract Class <strong>Monitor.java</strong> which is subclassed by a Class <strong>EmailMonitor.java</strong>. </p>
<p>The method:</p>
<pre><code>public abstract List<? extends MonitorAccount> performMonitor(List<? extends MonitorAccount> accounts)
</code></pre>
<p>is defined in <strong>Monitor.java</strong> and must be overridden in <strong>EmailMonitor.java</strong>.</p>
<p>I currently have the method overridden in <strong>EmailMonitor.java</strong> as follows:</p>
<pre><code>@Override
public List<EmailAccount> performMonitor(List<EmailAccount> emailAccounts) {
//...unrelated logic
return emailAccounts;
}
</code></pre>
<p>However, this produces the compile time error: </p>
<p><code>Name clash: The method performMonitor(List<EmailAccount>) of type EmailMonitor has the same erasure as performMonitor(Lis<? extends MonitorAccount> emailAccounts) of type Monitor but does not override it</code></p>
<p><code>EmailAccount</code> is a subclass of <code>MonitorAccount</code>, so (in my mind at least) overriding it in this way makes perfect sense. Seeing as the compiler is not happy with my logic though, How should I go about this correctly while still keeping my compile time checks to make sure that all calls to <code>EmailMonitor.performMonitor()</code> receive Lists of <code>EmailAccount</code> rather than some other type of <code>MonitorAccount</code>?
</p></p>

239,682 | <p>When reading the registry for file names I get 3 entries loading into my combo box for every 1 registry entry. If I have 1 file listed in the registry I would see :</p>
<p>Combo box values:</p>
<p>c:\file1.txt</p>
<p><-----Blank here</p>
<p>c:\file1.txt</p>
<p>I have found the problem lies in this code, it hits 'if (previousFiles != null)' 3 times. How should I correct this?</p>
<pre><code>for (int i = 0; i <= 5; i++)
{
Object previousFiles = OurKey.GetValue("Files" + i);
if (previousFiles != null)

comboBox1.Items.Add(previousFiles.ToString());

239,725 | <p>When I try to add a HTTP header key/value pair on a <code>WebRequest</code> object, I get the following exception:</p>
<blockquote>
<p>This header must be modified using the appropriate property</p>
</blockquote>
<p>I've tried adding new values to the <code>Headers</code> collection by using the Add() method but I still get the same exception.</p>
<pre><code>webRequest.Headers.Add(HttpRequestHeader.Referer, "http://stackoverflow.com");
</code></pre>
<p>I can get around this by casting the WebRequest object to a HttpWebRequest and setting the properties such as <code>httpWebReq.Referer ="http://stackoverflow.com"</code>, but this only works for a handful of headers that are exposed via properties.</p>
<p>I'd like to know if there's a way to get a finer grained control over modifying headers with a request for a remote resource.</p>

239,744 | <p>I'm developing a SWT/JFace application using the libraries from Eclipse 3.4.1.
I encounter the following problem on Windows (Vista 32bit) and Ubuntu 8.10 32bit:</p>
<p>I create a menu bar in the createMenuManager method of the JFace ApplicationWindow. I add MenuManagers for file, edit and help.</p>
<p>I then add an ExitAction to the file MenuManager like so:</p>
<pre><code>filemenu.add(new ExitAction(this));
</code></pre>
<p>The ExitAction is defined this way:</p>
<pre><code>public class ExitAction extends Action {
final ApplicationWindow window;
public ExitAction(ApplicationWindow w) {
this.window = w;
setText("E&xit");
setToolTipText("Exit the application");
setAccelerator(SWT.MOD1 + 'Q');
}
}
</code></pre>
<p>Now when my application starts I want be able to press "CTRL+Q" to quit the application. This does however not work. Only AFTER I click on "File" in the menu bar and THEN clicking "CTRL+Q" the application will quit.</p>
<p>I've tried this with different accelerators- same behavior.</p>
<p>It does work however if I create a "MenuItem" instead of an "Action" to contribute to the menu bar.</p>
<p>Is this a SWT bug or do I miss something?</p>
<p>Torsten.</p>

239,746 | <p>What is the correct way to check if a value is a date/number in Delphi?</p>
<p>I know other languages have functions like isDate and isNaN, but what is the Delphi equivalent? at the minute I have this</p>
<pre><code>function isNumeric(s1:string):boolean;
begin
// will throw exception if its not a number
// there must be a better way to do this!!
try
StrTofloat(s1);
result := TRUE ;
except
result := FALSE;
end;
end;
</code></pre>
<p>But throwing exceptions cant be good, and it makes debugging hard as I keep seeing the exception dialogue every time the code is called.</p>

239,786 | <p>I have put together the following mootools script</p>
<pre><code> window.addEvent('domready', function() {

var log = $('log_res');
function updateData (url,target)
{
new Ajax(url,{
method: 'get',
update: $(target),
onComplete: function() {
log.removeClass('ajax-loading');} }).request();
log.empty().addClass('ajax-loading');
}
var update = function(){ updateData ( shouts, 'log_res' ); };
update(); // call it immediately
update.periodical(10000); // and then periodically
});
</code></pre>
<p>heres the html</p>
<pre><code><div id="AJAX">
<h3>Ajax Response</h3>
<div id="log_res">exercise</div>
</div>
</code></pre>
<p>its using moo 1.1.</p>
<p>The above works fine, the page loads then the ajax request kicks in div id log_res has a class of ajax-loading whilst its updating, and when its finished the text exercise in the div is replaced with whatever the ajax has returned (yippee). But I want to put some custom HTML into the div WHILST the page is loading, because the ajax-loading class is not enough to contain the information, i also want to put a spinny flasher into the div whilst the ajax request is retrieving the information.
Hope that makes sense!</p>

<p>Is there anyway that I can add or remove HttpModules from and to the pipeline at runtime without having a corresponding entry in the Web.Config, or do I have to programmatically edit the Web.Config when adding / removing modules?

I need to make sure that the multiplier does not create an illogical situation where buying 1 more item would put the order over the maximum allowed. Thus the factors will give a list of valid values for my test data.</p>

239,866 | <p>I'm writing a license agreement dialog box with Win32 and I'm stumped. As usual with these things I want the "accept/don't accept" buttons to become enabled when the slider of the scroll bar of the richedit control hits bottom, but I can't find a way to get notified of that event. The earliest I've been able to learn about it is when the user releases the left mouse button.</p>
<p>Is there a way to do this?</p>
<p>Here's what I tried so far: </p>
<ul>
<li><code>WM_VSCROLL</code> and <code>WM_LBUTTONUP</code> in richedit's wndproc </li>
<li><code>EN_MSGFILTER</code> notification in dlgproc (yes the filter mask is getting set)</li>
<li><code>WM_VSCROLL</code> and <code>WM_LBUTTONUP</code> in dlgproc.</li>
<li><code>EN_VSCROLL</code> notification in dlgproc</li>
</ul>
<p>I got so desperate I tried polling but that didn't work either because apparently timer messages stop arriving while the mouse button is down on the slider. I tried both:</p>
<ul>
<li>timer callback (to poll) in dlgproc</li>
<li>timer callback (to poll) in richedit's wndproc</li>

239,876 | <p>What is the best way of storing data out to a file on a network, which will be later read in again programmatically. Target platform for the program is Linux (Fedora), but it will need to write out a file to a Windows (XP) machine</p>
<p>This needs to be in C++, there will be a high number of write / read events so it needs to be efficient, and the data needs to be written out in such a way that it can be read back in easily.</p>
<p>The whole file may not be being read back in, I'll need to search for a specific block of data in the file and read that back in.</p>
<p>Will simple binary stream writer do?
How should I store the data - XML?</p>
<p>Anything else I need to worry about?</p>
<hr>
<p><strong>UPDATE :</strong> To clarify, here are some answers to <strong><em>peterchen's</em></strong> points</p>
<blockquote>
<p>Please clarify:</p>
<p><strong>* do you only append blocks, or do you
also need to remove / update them?</strong></p>
</blockquote>
<p>I only need to append to the end of the file, but will need to search through it and retrieve from any point in it</p>
<blockquote>
<pre><code>*** are all blocks of the same size?**
</code></pre>
</blockquote>
<p>No, the data will vary in size - some will be free text comments (like a post here) others will be specific object-like data (sets of parameters)</p>
<blockquote>
<pre><code>*** is it necessary to be a single file?**
</code></pre>
</blockquote>
<p>No, but desirable</p>
<blockquote>
<pre><code>*** by which criteria do you need to locate blocks?**
</code></pre>
</blockquote>
<p>By data type and by timestamp. For example, if I periodically write out a specific set of parameters, in amognst other data, like free text, I want to find the value of those parameters at a cerain date/time - so I'll need to search for the time I wrote out those parameters nearest that date and read them back in.</p>
<blockquote>
<pre><code>*** must the data be readable for other applications?**
</code></pre>
</blockquote>
<p>No.</p>
<blockquote>
<pre><code>*** do you need concurrent access?**
</code></pre>
</blockquote>
<p>Yes, I may be continuing to write as I read. but should only ever do one write at a time.</p>
<blockquote>
<pre><code>*** Amount of data (per block / total) - kilo, mega, giga, tera?**
</code></pre>
</blockquote>
<p>Amount of data will be low per write... from a number of bytes to a coupe hundred bytes - total should see no more than few hundred kilobytes possible a fwe megabytes. (still unsure as yet)</p>
<p>**> If you need all of this, rolling your own will be a challenge, I would definitely </p>
<blockquote>
<p>recommend to use a database. If you need less than that, please specify so we can
recommend.**</p>
</blockquote>
<p>A database would over complicate the system so that is not an option unfortunately.</p>

239,909 | <p>I have a property called "IsSecureConnection" that is part of my object's interface. This makes sense for most implementations of the interface, however, in some implementations I would like to make the property ReadOnly. </p>
<p>Should I omit this property from the object's interface even though it is required by all of the implementations (though slightly different on occasion)?</p>
<p>Thanks!</p>

239,910 | <p>We have a situation where a C# application is working with SQL CE 3.5 . To allow for a legacy program to use some of its features we have produced a C++ dll which uses interop to extract the info that it needs from the C# program. For this to work, the C#-program needs to access the database. Its not a very complex scenario.</p>
<p>When trying to deploy with a private install some problems occur though.
<strong>There is no problem with the C# program, it can access the database and work with it without any problems.</strong></p>
<p><strong>But when trying to access functions in the C#-program through the C++ interop which forces the C#-program to access the database, we get a crash with the exception saying that "...the Provider: System.Data.SqlServerCe.3.5 is not installed".</strong></p>
<p>This is obviously because we cannot add a App.config file to the executing program.</p>
<p>How can we get around this? Is there another way to fix this? Any other forms of SQL CE 3.5 install methods are out of the question. So we must get this to work.</p>
<p>Regards,</p>
<p>P</p>
<p><strong>Edit:</strong></p>
<p>I'm not working against SQL CE directly, but through Linq2SQL. I have tried to add config files to all my dll's, it does not help. It seems to only matter if the executable file have got a app.config.</p>
<p>The exception thrown says - The provider System.Data.SqlServerCe.3.5 is not installed.</p>
<p>And the latest function to be called according to the stack trace is
System.Data.Linq.SqlClient.SqlProvider.System.Data.Linq.Provider.IProvider.Initialize(...).</p>
<p><strong>Edit 2</strong></p>
<p>I have added all the files necessery for the deployment to work. As I wrote above, it works if I use the program dll (which uses Linq 2 Sql) through a .net executable with a app.config file that specifies where to look for the SQL CE 3.5 dll. Deployment will <em>not</em> work with only the files, an app.config file is necessary.</p>
<p>The problem is that we have to use the dll file through a C++ executable which have no means of telling .net where to look for the Sql Ce 3.5 dll.</p>

239,912 | <p>Is there a Python class that wraps the <code>file</code> interface (read, write etc.) around a string? I mean something like the <code>stringstream</code> classes in C++.</p>
<p>I was thinking of using it to redirect the output of <code>print</code> into a string, like this</p>
<pre><code>sys.stdout = string_wrapper()
print "foo", "bar", "baz"
s = sys.stdout.to_string() #now s == "foo bar baz"
</code></pre>

239,938 | <p>i'm trying to change the number of rows in a <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tablelayoutpanel.aspx" rel="nofollow noreferrer">TableLayoutPanel</a> programatically (sometimes it needs to be four, sometimes five, and rarely six).</p>
<p>Unfortunatly changing the number of rows does not keep the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tablelayoutpanel.rowstyles.aspx" rel="nofollow noreferrer"><code>RowStyles</code></a> collection in sync, so you are then not able to set the height of the newly added rows. The following test code demonstrates this fact:</p>
<pre><code>private void button1_Click(object sender, EventArgs e)
{
//TableLayoutPanels start with 2 rows by default.
Debug.Assert(tableLayoutPanel1.RowStyles.Count ==
tableLayoutPanel1.RowCount);
//Cannot remove rows
tableLayoutPanel1.RowCount = 1;
Debug.Assert(tableLayoutPanel1.RowStyles.Count ==
tableLayoutPanel1.RowCount);
}
</code></pre>
<p>The second assertion fails.</p>
<pre><code>private void button2_Click(object sender, EventArgs e)
{
//TableLayoutPanels start with 2 rows by default.
Debug.Assert(tableLayoutPanel1.RowStyles.Count ==
tableLayoutPanel1.RowCount);
//Cannot add rows
tableLayoutPanel1.RowCount = 6;
Debug.Assert(tableLayoutPanel1.RowStyles.Count ==
tableLayoutPanel1.RowCount);
}
</code></pre>
<p>The second assertion fails.</p>
<p>So what's the proper programatic way to set the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tablelayoutpanel.rowcount.aspx" rel="nofollow noreferrer"><code>RowCount</code></a> property of a <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tablelayoutpanel.aspx" rel="nofollow noreferrer"><code>TableLayoutPanel</code></a>?</p>

239,945 | <p>I'm creating a really complex dynamic sql, it's got to return one row per user, but now I have to join against a one to many table. I do an outer join to make sure I get at least one row back (and can check for null to see if there's data in that table) but I have to make sure I only get one row back from this outer join part if there's multiple rows in this second table for this user.
So far I've come up with this: (sybase)</p>
<pre><code>SELECT a.user_id
FROM table1 a
,table2 b
WHERE a.user_id = b.user_id
AND a.sub_id = (
SELECT min(c.sub_id)
FROM table2 c
WHERE b.sub_id = c.sub_id
)
</code></pre>
<p>The subquery finds the min value in the one to many table for that particular user.</p>
<p>This works but I fear nastiness from doing correlated subqueries when table 1 and 2 get very large.
Is there a better way? I'm trying to dream up a way to get joins to do it, but I'm not seeing it.
Also saying "where rowcount=1" or "top 1" doesn't help me, because I'm not trying to fix the above query, I'm ADDING the above to an already complex query.</p>

240,013 | <p>I have two databases, one is an MS Access file, the other is a SQL Server database. I need to create a SELECT command that filters data from the SQL Server database based on the data in the Access database. What is the best way to accomplish this with ADO.NET?</p>
<p>Can I pull the required data from each database into two new tables. Put these in a single Dataset. Then perform another SELECT command on the Dataset to combine the data?</p>
<p>Additional Information:
The Access database is not permanent. The Access file to use is set at runtime by the user.</p>
<p>Here's a bit of background information to explain why there are two databases. My company uses a CAD program to design buildings. The program stores materials used in the CAD model in an Access database. There is one file for each model. I am writing a program that will generate costing information for each model. This is based on current material prices stored in a SQL Server database. </p>
<hr>
<p><strong>My Solution</strong></p>
<p>I ended up just importing the data in the access db into a temporary table in the SQL server db. Performing all the necessary processing then removing the temporary table. It wasn't a pretty solution but it worked.</p>

240,016 | <p>I have created a class for a dashboard item which will hold information such as placement on the dashboard, description, etc. I am currently using a pair of Collections to hold those dashboard items contained in the "library" and those items showing on the dashboard itself. I have been asked to make this dashboard multi-tab, and my first inclination was to make a new Collection for each tab. For this I would want some type of array or collection which could have many of these dashboard item collections added to it as more tabs are added to the dashboard.</p>
<p>Is this possible, and if so, could I get a little code snip for the declaration of such a collection? I have considered using a single collection with a variable to show which tab the item will be shown in... However, the display and routines to manage dashboard item movement between screen and library currently need those individual collections.</p>
<p>Edit: Thank you for your answers. While I do find them all interesting I believe I am going to go with James solution and will be marking it as the accepted answer.</p>

240,033 | <p>I'll preface this by saying that I usually work in C#/.Net.</p>
<p>Normally, I use a naming scheme that puts common, reusable components into a namespace that reflects our organization and project-specific components into a namespace tied to the project. One of the reasons I do this is that I sometimes share my components with others outside my department, but within the organization. Project-specific namespaces are typically prefaced with the name or abbreviation of the department. When I reuse code between projects, I typically migrate it into one of the organization-based namespaces.</p>
<p>For example:</p>
<p><code>UIOWA.DirectoryServices</code> contains classes that deal with the specific implementation of our Active Directory.</p>
<p><code>UIOWA.Calendar</code> contains classes that deal with the University's master calendar.</p>
<p><code>LST.Inventory.Datalayer</code> holds the classes implementing the data layer of the Learning Spaces Technology group inventory application.</p>
<p>I'm embarking on a project now for an entity that has a fuzzier connection to the Unviersity (a student group that runs a charity event) that has the potential to be sold outside of our University and, thus, it doesn't really fit into my normal naming conventions, i.e., the department is only the first customer of potentially many that might use the project.</p>
<p>My inclination is to go the organization naming route and create an "organizational project" name space for this application. I'd like to hear how others handle this and any advice you might have.</p>
<p>Thanks.</p>
<p><strong>See also</strong> this related question about <a href="https://stackoverflow.com/questions/123114/how-do-you-organize-your-namespaces">namespace organization</a>.</p>
<p><strong>EDIT</strong></p>
<p>I ended up creating the org/project namespace <code>UIOWA.MasterEvent</code> and deriving further namespaces from there. Still interested in other opinions for future projects.</p>

240,058 | <p>I need a timer tick with 1ms resolution under linux. It is used to increment a timer value that in turn is used to see if various Events should be triggered. The POSIX timerfd_create is not an option because of the glibc requirement. I tried timer_create and timer_settimer, but the best I get from them is a 10ms resolution, smaller values seem to default to 10ms resolution. Getittimer and setitimer have a 10 ms resolution according to the manpage.</p>
<p>The only way to do this timer I can currently think of is to use clock_gettime with CLOCK_MONOTONIC in my main loop an test if a ms has passed, and if so to increase the counter (and then check if the various Events should fire).</p>
<p>Is there a better way to do this than to constantly query in the main loop? What is the recommended solution to this?</p>
<p>The language I am using is plain old c</p>
<p><strong>Update</strong><br>
I am using a 2.6.26 Kernel. I know you can have it interrupt at 1kHz, and the POSIX timer_* functions then can be programmed to up to 1ms but that seems not to be reliable and I don't want to use that, because it may need a new kernel on some Systems. Some stock Kernel seem to still have the 100Hz configured. And I would need to detect that. The application may be run on something else than my System :)</p>
<p>I can not sleep for 1ms because there may be network events I have to react to.</p>
<p><strong>How I resolved it</strong>
Since it is not that important I simply declared that the global timer has a 100ms resolution. All events using their own timer have to set at least 100ms for timer expiration. I was more or less wondering if there would be a better way, hence the question.</p>
<p><strong>Why I accepted the answer</strong>
I think the answer from freespace best described why it is not really possible without a realtime Linux System.</p>

240,061 | <p>I have a very large C project with many separate C files and headers and many dozens of contributors. Many contributors do not have a strong knowledge of makefiles and dependencies, resulting in the not uncommon problem where you almost always have to "make clean" before you can trust "make" to have produced correct output.</p>
<p>If make took minutes, this wouldn't be an issue, but it's nearly 2 hours on a fast machine now, and people are starting to check in code that works when they make, but they don't clean first and their code ultimately breaks the build. Don't ask why these aren't caught by the build manager before a new baseline is cut...</p>
<p>Yes, we shouldn't have let it go this far.</p>
<p>Yes, we're educating our developers.</p>
<p>As usual, we don't have time to stop everything and fix it by hand.</p>
<p>I'm thinking there are tools along these lines:</p>
<ul>
<li>Are there automated tools to help build correct dependency information for an existing project from the C and H files?</li>
<li>Are there automated tools to describe dependency information according to the makefiles?</li>
<li>Is there a holy grail of a tool to describe the differences between the above two dependency trees?</li>
</ul>
<p>But what else can/should be done to resolve this issue?</p>
<p>Thanks in advance...</p>
<p>-Adam</p>

240,090 | <p>We have a ASP.Net 2.0 web application up and running with the server in the Midwest (Eastern Standard Time). At this moment all of our customers are in the same time zone as the server. We are bringing another server online in Arizona (Mountain Standard Time).</p>
<p>We are storing all our times in a SQL 2005 database via C# codebehind DateTime.UtcNow.</p>
<p>During testing we encountered some time zone conversion issues.
Our problem is that in the web browser our times are displaying the Mountain Standard Time instead of the time zone we are testing from which is Eastern Standard Time. </p>
<p>When we enter new information it gets stored as UTC in the database, but when we go to view that info in the browser it is displaying the Mountain Standard Time.
Below is the code which takes the UTC value from the database and displays it in the browser.</p>
<pre><code>lblUpdatedDate.Text = Convert.ToDateTime(dr["UpdatedDate"]).ToLocalTime().ToString();
</code></pre>
<p>The above code returns Mountain Standard Time where the server is, not Eastern Standard Time where the browser is running from. How do we get the time to display where the user is?</p>

240,098 | <p>I'm using an HTML sanitizing whitelist code found here:<br>
<a href="http://refactormycode.com/codes/333-sanitize-html" rel="nofollow noreferrer">http://refactormycode.com/codes/333-sanitize-html</a></p>
<p>I needed to add the "font" tag as an additional tag to match, so I tried adding this condition after the <code><img</code> tag check </p>
<pre><code>if (tagname.StartsWith("<font"))
{
// detailed <font> tag checking
// Non-escaped expression (for testing in a Regex editor app)
// ^<font(\s*size="\d{1}")?(\s*color="((#[0-9a-f]{6})|(#[0-9a-f]{3})|red|green|blue|black|white)")?(\s*face="(Arial|Courier New|Garamond|Georgia|Tahoma|Verdana)")?\s*?>$
if (!IsMatch(tagname, @"<font
(\s*size=""\d{1}"")?
(\s*color=""((#[0-9a-f]{6})|(#[0-9a-f]{3})|red|green|blue|black|white)"")?
(\s*face=""(Arial|Courier New|Garamond|Georgia|Tahoma|Verdana)"")?
\s*?>"))
{
html = html.Remove(tag.Index, tag.Length);
}
}
</code></pre>
<p>Aside from the condition above, my code is almost identical to the code in the page I linked to. When I try to test this in C#, it throws an exception saying "<code>Not enough )'s</code>". I've counted the parenthesis several times and I've run the expression through a few online Javascript-based regex testers and none of them seem to tell me of any problems.</p>
<p>Am I missing something in my Regex that is causing a parenthesis to escape? What do I need to do to fix this?</p>
<p><strong>UPDATE</strong><br>
After a lot of trial and error, I remembered that the <code>#</code> sign is a comment in regexes. The key to fixing this is to escape the <code>#</code> character. In case anyone else comes across the same problem, I've included my fix (just escaping the <code>#</code> sign) </p>
<pre><code>if (tagname.StartsWith("<font"))
{
// detailed <font> tag checking
// Non-escaped expression (for testing in a Regex editor app)
// ^<font(\s*size="\d{1}")?(\s*color="((#[0-9a-f]{6})|(#[0-9a-f]{3})|red|green|blue|black|white)")?(\s*face="(Arial|Courier New|Garamond|Georgia|Tahoma|Verdana)")?\s*?>$

240,102 | <p>I'm developing an <code>ActiveX EXE</code> that exposes an specific class to a third-party software. This third-party software instanciates an object of this class and uses its methods. </p>
<p>Strangely, this third-party software destroys its object of my exposed class as soon as it calls an specific method, but I have no idea why this happens.</p>
<p>The only clue I have is that this method is the only one that returns a value. All the other ones are simple 'subs' that do not return any value, and when they are called nothing wrong happens.</p>
<p>I'm using VB6.</p>
<p>Do you guys have any idea of why it's happening?</p>

240,166 | <p>I'm using the javax.mail system, and having problems with "Invalid Address" exceptions. Here's the basics of the code:</p>
<pre><code> // Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", m_sending_host);
// Get session
Session session = Session.getDefaultInstance(props, new Authenticator(){
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(m_sending_user, m_sending_pass);
}
});
// Define message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(m_sending_from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(vcea.get(i).emailaddr));
message.setSubject( replaceEnvVars(subject) );
message.setText(replaceEnvVars(body));
// Send message
try {
Transport.send(message);
} catch (Exception e){
Log.Error("Error sending e-mail to addr (%s): %s",
vcea.get(i).emailaddr, e.getLocalizedMessage() );
}
</code></pre>
<p>The issue is that the above code does work, sometimes. But for some e-mail addresses that I know to be valid (because I can send to them via a standard e-mail client), the above code will throw an "Invalid Address" exception when trying to send.</p>
<p>Any clues or hints would be greatly appreciated.</p>
<p>--Update: problem with authentication.</p>
<p>Ok, here's what I've discovered was going on. When receiving e-mail, the code above correctly sets up authentication and the Authenticator.getPasswordAuthentication() callback is actually invoked.</p>
<p>Not so when sending e-mail. You have to do a bit more. Add this:</p>
<pre><code> // Setup mail server
props.put("mail.smtp.host", m_sending_host);
props.put("mail.smtp.auth", "true");
</code></pre>
<p>which will force the javax.mail API to do the login authentication. And then use an actual Transport instance instead of the static .send() method:</p>
<pre><code> Transport t = session.getTransport(m_sending_protocol);
t.connect(m_sending_user, m_sending_pass);
</code></pre>
<p>...</p>
<pre><code> // Send message
try {
t.sendMessage(message, message.getAllRecipients());
} catch (Exception e){
</code></pre>
<p>Without forcing the authentication, the mail server saw me as an unauthorized relay, and just shut me down. The difference between the addresses that "worked" and the addresses that didn't was that the ones that "worked" were all local to the mail server. Therefore, it simply accepted them. But for any non-local "relay" addresses, it would reject the message because my authentication information hadn't been presented by the javax.mail API when I thought it would have.</p>
<p>Thanks for the clues to prompt me to look at the mail server side of things as well.</p>

240,184 | <p>I'm writing a CESetup.dll for a Windows Mobile app. It must be unmanaged, which I have little experience with. So I'm unsure of whether I should free the memory I allocate and how I do it.</p>
<p>Here's the function I've written:</p>
<pre><code> Uninstall_Init(
HWND hwndParent,
LPCTSTR pszInstallDir
)
{
LPTSTR folderPath = new TCHAR[256];
_stprintf(folderPath, _T("%s\\cache"), pszInstallDir);
EmptyDirectory(folderPath);
RemoveDirectory(folderPath);
_stprintf(folderPath, _T("%s\\mobileadmin.dat"), pszInstallDir);
DeleteFile(folderPath);
// To continue uninstallation, return codeUNINSTALL_INIT_CONTINUE
// If you want to cancel installation,
// return codeUNINSTALL_INIT_CANCEL
return codeUNINSTALL_INIT_CONTINUE;
}
</code></pre>
<p>As I understand it, folderPath is allocated on the heap. EmptyDirectory() is my own function that removes all content in the directory. RemoveDirectory() and DeleteFile() are system calls.</p>
<p>My question is should I deallocate <code>folderPath</code> before the function exits? If I should, how do I do it?</p>

Sending them on their merry way will work in about 50% of the cases. Some things like spaces are already encoded somewhere (I'm guessing in the Html.BuildUrlFromExpression does). Other things though (like "/" and "*") are not.</p>
<p>Now I don't know what to do anymore because if I encode them myself, my encoding will get partially encoded again and end up wrong. If I don't encode them, some characters will not get through.</p>
<p>What I did is manually .replace() the characters I had problems with.<br>
This is off course not a good idea.</p>
<p>Ideas?</p>
<p><strong>--Edit--</strong><br>
<strong>I know there are a multitude of encoding/decoding libraries at my disposal.</strong>
It just looks like the mvc framework is already trying to do it for me, but not completely.</p>
<pre><code><a href="<%=Html.BuildUrlFromExpression<SearchController>(c=>c.Search("", 1, "a \v/&irdStr*ng"))%>" title="my hat's awesome!">
</code></pre>
<p>will render me</p>
<pre><code><a href="/Search.mvc/en/Search/1/a%20%5Cv/&irdStr*ng" title="my hat's awesome!">
</code></pre>
<p>Notice how the forward slash, asterisk and ampersand are not escaped.
Why are some escaped and others not? How can I now escape this properly?</p>
<p>Am I doing something wrong or is it the framework?</p>
