268,592 | <p>For my website I configured some custom error pages.
If I generate a 404, the redirect works fine.
When hitting a 400, the "bad request" text shows up instead of the configured URl.</p>
<p>As a test I copied the URL from 404 to 400. No change.
Then I changed the redirect to a file. No change.</p>
<p>Any ideas?</p>

268,595 | <p>I am trying to put version information to my C# GUI framework retrieved from the latest ClearCase label. This was originally done from Visual Soursafe as below. </p>
<pre><code>vssDB = new VSSDatabaseClass();
vssDB.Open( databaseName, "vssadmin", "vssadmin" );
VSSItem item = vssDB.get_VSSItem( @"$\BuildDCP.bat", false );
foreach(VSSVersion vssVersion in item.get_Versions(0))
{
// Pull the first non-blank label and use that
if ( vssVersion.Label != "" )
{
labelID = vssVersion.Label.ToString();
break;
}
}
</code></pre>
<p>I am trying to do something similar using ClearCase since we changed our source code control from VSS to CC. Any help would be greatly appreciated.</p>
<p>Thanks!</p>

268,652 | <p>I'm using java and referring to the "double" datatype.
To keep it short, I'm reading some values from standard input that I read in my code as doubles (I would much rather use something like BigInteger but right now it's not possible).</p>
<p>I expect to get double values from the user but sometimes they might input things like:
999999999999999999999999999.9999999999
which I think is beyond an accurate representation for double and get's rounded to 1.0E27 (probably).</p>
<p>I would like to get some pointers on how to detect whether a specific value would be unable to be accurately represented in a double and would require rounding (so that I could refuse that value or other such actions).</p>
<p>Thank you very much</p>

268,656 | <p>I'm trying to control the main timeline of my flash application from a MovieClip that is a child of the main stage. Apparently, in ActionScript 2, you could do that using _root, but using root (since _root no longer exists) now gives an error:</p>
<pre><code>root.play();
</code></pre>
<p>"1061: Call to a possibly undefined method play through a reference with static type flash.display:DisplayObjectContainer."</p>
<p>Using the Stage class also doesn't work:</p>
<pre><code>stage.play();

<p>"1061: Call to a possibly undefined method play through a reference with static type flash.display:Stage."</p>
<p>Is there any way to do this?</p>

268,674 | <p>I have this ListBox which is bound to an ObservableCollection. Each object in the list implements an interface called ISelectable </p>
<pre><code>public interface ISelectable : INotifyPropertyChanged
{
event EventHandler IsSelected;
bool Selected { get; set; }
string DisplayText { get; }
}
</code></pre>
<p>I want to keep track of which object is selected regardless of how it is selected. The user could click on the representation of the object in the ListBox but it could also be that an object is selected via code. If the user selects an object via the ListBox I cast the the selected item to an ISelectable and set the Selected property to true.</p>
<pre><code>ISelectable selectable = (ISelectable)e.AddedItems[0];
selectable.Selected = true;
</code></pre>
<p>My problem is that when I select the object using code I can't get ListBox to change the selected item. I'm using a DataTemplate to show the selected object in a different color which means everything is displayed correctly. But the ListBox has the last object the user clicked as the SelectedItem which means that item can't be clicked without first selecting another object in the list.</p>
<p>Anyone got any idea on how to solve this? I pretty sure I can accomplish what I want by writing some custom code to handle the Mouse and Keyboard events but I rather not. I have tried adding a SelectedItem property to the collection and bind it to the ListBox's SelectItemProperty but no luck. </p>

268,698 | <p>This is somewhat of a follow-up question to this <a href="https://stackoverflow.com/questions/267045/is-there-a-benefit-to-having-both-an-abstract-class-and-an-interface">question</a>.</p>
<p>Suppose I have an inheritance tree as follows:</p>
<pre><code>Car -> Ford -> Mustang -> MustangGT
</code></pre>
<p>Is there a benefit to defining interfaces for <em>each</em> of these classes? Example:</p>
<pre><code>ICar -> IFord -> IMustang -> IMustangGT
</code></pre>
<p>I can see that maybe other classes (like <code>Chevy</code>) would want to implement <code>Icar</code> or <code>IFord</code> and maybe even <code>IMustang</code>, but probably not <code>IMustangGT</code> because it is so specific. Are the interfaces superfluous in this case?</p>
<p>Also, I would think that any class that would want to implement <code>IFord</code> would definitely want to use its one inheritance by inheriting from <code>Ford</code> so as not to duplicate code. If that is a given, what is the benefit of also implementing <code>IFord</code>?</p>

268,771 | <p>Ok, so I have this regex:</p>
<pre><code>( |^|>)(((((((\+|00)(31|32)( )?(\(0\))?)|0)([0-9]{2})(-)?( )?)?)([0-9]{7}))|((((((\+|00)(31|32)( )?(\(0\))?)|0)([0-9]{3})(-)?( )?)?)([0-9]{6}))|((((((\+|00)(31|32)( )?(\(0\))?)|0)([0-9]{1})(-)?( )?)?)([0-9]{8})))( |$|<)
</code></pre>
<p>It formats Dutch and Belgian phone numbers (I only want those hence the 31 and 32 as country code).</p>
<p>Its not much fun to decipher but as you can see it also has a lot duplicated. but now it does handles it very accurately</p>
<p>All the following European formatted phone numbers are accepted</p>
<pre><code>0031201234567
0031223234567
0031612345678
+31(0)20-1234567
+31(0)223-234567
+31(0)6-12345678
020-1234567
0223-234567
06-12345678
0201234567
0223234567
0612345678
</code></pre>
<p>and the following false formatted ones are not</p>
<pre><code>06-1234567 (mobile phone number in the Netherlands should have 8 numbers after 06 )
0223-1234567 (area code with home phone)
</code></pre>
<p>as opposed to this which is good.</p>
<pre><code>020-1234567 (area code with 3 numbers has 7 numbers for the phone as opposed to a 4 number area code which can only have 6 numbers for phone number)
</code></pre>
<p>As you can see it's the '-' character that makes it a little difficult but I need it in there because it's a part of the formatting usually used by people, and I want to be able to parse them all.</p>
<p>Now is my question... do you see a way to simplify this regex (or even improve it if you see a fault in it), while keeping the same rules?</p>
<p>You can test it at <a href="http://regextester.com/" rel="nofollow noreferrer">regextester.com</a></p>
<p>(The '( |^|>)' is to check if it is at the start of a word with the possibility it being preceded by either a new line or a '>'. I search for the phone numbers in HTML pages.) </p>

268,778 | <p>I have a class called EventConsumer which defines an event EventConsumed and a method OnEventConsumed as follows:</p>
<pre><code>public event EventHandler EventConsumed;
public virtual void OnEventConsumed(object sender, EventArgs e)
{
if (EventConsumed != null)
EventConsumed(this, e);
}
</code></pre>
<p>I need to add attributes to the at OnEventConsumed runtime, so I'm generating a subclass using System.Reflection.Emit. What I want is the MSIL equivalent of this:</p>
<pre><code>public override void OnEventConsumed(object sender, EventArgs e)
{
base.OnEventConsumed(sender, e);
}
</code></pre>
<p>What I have so far is this:</p>
<pre><code>...
MethodInfo baseMethod = typeof(EventConsumer).GetMethod("OnEventConsumed");
MethodBuilder methodBuilder = typeBuilder.DefineMethod("OnEventConsumed",
baseMethod.Attributes,
baseMethod.CallingConvention,
typeof(void),
new Type[] {typeof(object),
typeof(EventArgs)});
ILGenerator ilGenerator = methodBuilder.GetILGenerator();
// load the first two args onto the stack
ilGenerator.Emit(OpCodes.Ldarg_1);
ilGenerator.Emit(OpCodes.Ldarg_2);
// call the base method
ilGenerator.EmitCall(OpCodes.Callvirt, baseMethod, new Type[0] );
// return
ilGenerator.Emit(OpCodes.Ret);
...
</code></pre>
<p>I create the type, create an instance of the type, and call its OnEventConsumed function, and I get:</p>
<pre><code>Common Language Runtime detected an invalid program.
</code></pre>
<p>...which is not exactly helpful. What am I doing wrong? What's the correct MSIL to call the base class's event handler?</p>

268,802 | <p>In my Silverlight app I want a multi-line text box to expand every time the user hits Enter.</p>
<p>The difficult part is how to calculate the correct height based on the number of text lines.</p>
<p>I have tried the following but the textbox becomes too small:</p>
<pre><code>box.Height = box.FontSize*lineCount + box.Padding.Top + box.Padding.Bottom + box.BorderThickness.Top + box.BorderThickness.Bottom;
</code></pre>
<p>What am I missing here? Or maybe it can be done automatically somehow?</p>
<p>Thanks,
Jacob</p>
<p><strong>Edit:</strong> I suspect the problem to be in the FontSize property (does it use another size unit?)</p>

268,808 | <p>I have a need to determine what security group(s) a user is a member of from within a SQL Server Reporting Services report. Access to the report will be driven by membership to one of two groups: 'report_name_summary' and 'report_name_detail'. Once the user is executing the report, we want to be able to use their membership (or lack of membership) in the 'report_name_detail' group to determine whether or not a "drill down" should be allowed.</p>
<p>I don't know of any way out of the box to access the current user's AD security group membership, but am open to any suggestions for being able to access this info from within the report.</p>

268,814 | <p>Consider this:</p>
<pre><code>public class TestClass {
private String a;
private String b;
public TestClass()
{
a = "initialized";
}
public void doSomething()
{
String c;
a.notify(); // This is fine
b.notify(); // This is fine - but will end in an exception
c.notify(); // "Local variable c may not have been initialised"
}
}
</code></pre>
<p>I don't get it. "b" is never initialized but will give the same run-time error as "c", which is a compile-time error. Why the difference between local variables and members?</p>
<p><strong>Edit</strong>: making the members private was my initial intention, and the question still stands...</p>

268,816 | <p>What are some strategies to achieve code separation in AJAX applications?</p>
<p>I am building a PHP application that I would like to have a nice AJAX front end on. I have long since learned to use some kind of templating in my PHP code to make sure I maintain good separation between my logic and display code, but I'm having trouble finding good ways to do this with the JavaScript code on the front end. I'm using jQuery to make the fetching of XML data and DOM manipulation easy, but I'm finding that the logic and layout code is starting to intermix.</p>
<p>The real problem is that I get XML data from the back end that then has to be reformatted and helpful text has to be wrapped around it (directions and the like). I've thought about sending over already formatted HTML, but that would require extensive reworking of the backend, and there must be a better way than what I have come up with on my own.</p>

268,824 | <p>We're working now on the design of a new API for our product, which will be exposed via web services. We have a dispute whether we should use strict parameters with well defined types (my opinion) or strings that will contain XML in whatever structure needed. It is quite obvious that ideally using a strict signature is safer, and it will allow our users to use tools like wsdl2java. OTOH, our product is developing rapidly, and if the parameters of a service will have to be changed, using XML (passed as a string or anyType - not complex type, which is well defined type) will not require the change of the interface.</p>
<p>So, what I'm asking for is basically rule of thumb recommendations - would you prefer using strict types or flexible XML? Have you had any significant problems using either way?</p>
<p>Thanks,
Eran</p>

268,853 | <p>This is just to satisfy my own curiosity.</p>
<p>Is there an implementation of this:</p>
<pre><code>float InvSqrt (float x)
{
float xhalf = 0.5f*x;
int i = *(int*)&x;
i = 0x5f3759df - (i>>1);
x = *(float*)&i;
x = x*(1.5f - xhalf*x*x);
return x;
}
</code></pre>
<p>in C#? If it exists, post the code. </p>
<p>I guess I should have mentioned I was looking for a "safe" implementation... Either way, the BitConverter code solves the problem. The union idea is interesting. I'll test it and post my results.</p>
<p>Edit:
As expected, the unsafe method is the quickest, followed by using a union (inside the function), followed by the BitConverter. The functions were executed 10000000 times, and the I used the System.Diagnostics.Stopwatch class for timing. The results of the calculations are show in brackets.</p>
<pre><code>Input: 79.67
BitConverter Method: 00:00:01.2809018 (0.1120187)
Union Method: 00:00:00.6838758 (0.1120187)
Unsafe Method: 00:00:00.3376401 (0.1120187)
</code></pre>
<p>For completeness, I tested the built-in Math.Pow method, and the "naive" method (1/Sqrt(x)).</p>
<pre><code>Math.Pow(x, -0.5): 00:00:01.7133228 (0.112034710535584)
1 / Math.Sqrt(x): 00:00:00.3757084 (0.1120347)
</code></pre>
<p>The difference between 1 / Math.Sqrt() is so small that I don't think one needs to resort to the Unsafe Fast InvSqrt() method in C# (or any other unsafe method). Unless one <em>really</em> needs to squeeze out that last bit of juice from the CPU... 1/Math.Sqrt() is also much more accurate.</p>

<p>While I do not get an error, I do not get the expected result, instead I get this:</p>
<pre><code>+---------------------------------------------------+

+---------------------------------------------------+
| NULL |
+---------------------------------------------------+
1 row in set, 1 warning (0.01 sec)
</code></pre>
<p>The access dates are in this format:</p>
<pre><code>06.10.2008 14:19:08
</code></pre>
<p>I am not sure what I am missing.</p>
<p>As a side question, I am wondering if it is possible when importing a csv file to change the data in a column before? I want to replace the insert_date and update_date fields with my own dates, and I am not sure if it would be easier to do this before importing or after.</p>

268,920 | <p>We have a decent sized object-oriented application. Whenever an object in the app is changed, the object changes are saved back to the DB. However, this has become less than ideal.</p>
<p>Currently, transactions are stored as a transaction and a set of transactionLI's.</p>
<p>The transaction table has fields for who, what, when, why, foreignKey, and foreignTable. The first four are self-explanatory. ForeignKey and foreignTable are used to determine which object changed.</p>
<p>TransactionLI has timestamp, key, val, oldVal, and a transactionID. This is basically a key/value/oldValue storage system.</p>
<p>The problem is that these two tables are used for every object in the application, so they're pretty big tables now. Using them for anything is slow. Indexes only help so much.</p>
<p>So we're thinking about other ways to do something like this. Things we've considered so far:
- Sharding these tables by something like the timestamp.
- Denormalizing the two tables and merge them into one.
- A combination of the two above.
- Doing something along the lines of serializing each object after a change and storing it in subversion.
- Probably something else, but I can't think of it right now.</p>
<p>The whole problem is that we'd like to have some mechanism for properly storing and searching through transactional data. Yeah you can force feed that into a relational database, but really, it's transactional data and should be stored accordingly.</p>
<p>What is everyone else doing?</p>

268,982 | <p>Please help!</p>
<p><em>Background info</em></p>
<p>I have a WPF application which accesses a SQL Server 2005 database. The database is running locally on the machine the application is running on.</p>
<p>Everywhere I use the Linq DataContext I use a using { } statement, and pass in a result of a function which returns a SqlConnection object which has been opened and had an SqlCommand executed using it before returning to the DataContext constructor.. I.e.</p>
<pre><code>// In the application code
using (DataContext db = new DataContext(GetConnection()))
{
... Code
}
</code></pre>
<p>where getConnection looks like this (I've stripped out the 'fluff' from the function to make it more readable, but there is no additional functionality that is missing).</p>
<pre><code>// Function which gets an opened connection which is given back to the DataContext constructor
public static System.Data.SqlClient.SqlConnection GetConnection()
{
System.Data.SqlClient.SqlConnection Conn = new System.Data.SqlClient.SqlConnection(/* The connection string */);
if ( Conn != null )
{
try
{
Conn.Open();
}
catch (System.Data.SqlClient.SqlException SDSCSEx)
{
/* Error Handling */
}
using (System.Data.SqlClient.SqlCommand SetCmd = new System.Data.SqlClient.SqlCommand())
{
SetCmd.Connection = Conn;
SetCmd.CommandType = System.Data.CommandType.Text;
string CurrentUserID = System.String.Empty;
SetCmd.CommandText = "DECLARE @B VARBINARY(36); SET @B = CAST('" + CurrentUserID + "' AS VARBINARY(36)); SET CONTEXT_INFO @B";
try
{
SetCmd.ExecuteNonQuery();
}
catch (System.Exception)
{
/* Error Handling */
}
}
return Conn;
}
</code></pre>
<p><strong>I do not think that the application being a WPF one has any bearing on the issue I am having.</strong></p>
<p><em>The issue I am having</em> </p>
<p>Despite the SqlConnection being disposed along with the DataContext in Sql Server Management studio I can still see loads of open connections with :</p>
<pre><code>status : 'Sleeping'
command : 'AWAITING COMMAND'
last SQL Transact Command Batch : DECLARE @B VARBINARY(36); SET @B = CAST('GUID' AS VARBINARY(36)); SET CONTEXT_INFO @B
</code></pre>
<p>Eventually the connection pool gets used up and the application can't continue. </p>
<p>So I can only conclude that somehow running the SQLCommand to set the Context_Info is meaning that the connection doesn't get disposed of when the DataContext gets disposed. </p>
<p>Can anyone spot anything obvious that would be stopping the connections from being closed and disposed of when the DataContext they are used by are disposed?</p>

269,010 | <p>I have created a proc that grabs all the user tables in a local DB on my machine. I want to be able to create a flat file of all my tables using BCP and SQL. Its a dummy database in SQL 2000 connecting through windows authentication. I have set my enviroment path variable in WinXP SP2. I have created new users to access the db, switched off my firewall, using trusted connection. I have tried dozens of forums, no luck. </p>
<p>In dos command prompt I get the same error. </p>
<p>SQLState = 37000, NativeError = 4060
Error = [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open database requested in login '[HelpDesk-EasyPay'. Login fails.</p>
<p>Here is my SP: </p>
<pre><code>@Path VARCHAR(100),
@UserName VARCHAR(15),
@PassWord VARCHAR(15),
@ServerName VARCHAR(15)
AS
set quoted_identifier off
set nocount on
declare @n int
declare @db varchar(40)
set @db=DB_NAME()
declare @TableName varchar(15)
declare @bcp varchar(200)
select identity(int,1,1) as tblNo,name tblname into #T from Sysobjects where xtype='u'
select @n=COUNT(*) from #T
WHILE (@n>0)
BEGIN
SELECT @TableName=tblname FROM #T WHERE tblno=@n
PRINT 'Now BCP out for table: ' + @TableName
SET @bcp = "master..xp_cmdshell 'BCP " + "[" + @db + ".." + @TableName + "]" + " OUT" + @Path + "" + @TableName+".txt -c -U" + @UserName + " -P" + @PassWord + " -S" + @ServerName + " -T" + "'"
EXEC(@bcp)
SET @n=@n-1
END
DROP TABLE #T
</code></pre>
<p>Can anyone advise. This seems to be a connection problem or BCP ? Not sure. </p>
<p>edit: I am running this from query analyzer because I have 118 tables to output to flat file. I seem to agree that its an authentication issue because I tried connecting to master db with username sa password root. which is what its set to and I get the same error: SQLState = 37000, NativeError = 4060</p>

269,017 | <p>So here is the simple code:</p>
<pre><code> [System.ComponentModel.DefaultValue(true)]
public bool AnyValue { get; set; }
</code></pre>
<p>I am sure I don't set AnyValue to false again (I just created it). This property is a property of a Page class of ASP.NET. And I am cheking the value in a button event handling function. But somehow it is still false.
I wonder when actually it is set true? On compile time? When class is instantiated?</p>
<p>What do you think about what I am doing wrong?</p>

269,044 | <p><strong>Background:</strong> I have an HTML page which lets you expand certain content. As only small portions of the page need to be loaded for such an expansion, it's done via JavaScript, and not by directing to a new URL/ HTML page. However, as a bonus the user is able to permalink to such expanded sections, i.e. send someone else a URL like</p>
<p><em><a href="http://example.com/#foobar" rel="noreferrer">http://example.com/#foobar</a></em></p>
<p>and have the "foobar" category be opened immediately for that other user. This works using parent.location.hash = 'foobar', so that part is fine.</p>
<p><strong>Now the question:</strong> When the user closes such a category on the page, I want to empty the URL fragment again, i.e. turn <a href="http://example.com/#foobar" rel="noreferrer">http://example.com/#foobar</a> into <a href="http://example.com/" rel="noreferrer">http://example.com/</a> to update the permalink display. However, doing so using <code>parent.location.hash = ''</code> causes a reload of the whole page (in Firefox 3, for instance), which I'd like to avoid. Using <code>window.location.href = '/#'</code> won't trigger a page reload, but leaves the somewhat unpretty-looking "#" sign in the URL. So is there a way in popular browsers to JavaScript-remove a URL anchor including the "#" sign without triggering a page refresh?</p>

269,060 | <p>I'm writing some mail-processing software in Python that is encountering strange bytes in header fields. I suspect this is just malformed mail; the message itself claims to be us-ascii, so I don't think there is a true encoding, but I'd like to get out a unicode string approximating the original one without throwing a <code>UnicodeDecodeError</code>.</p>
<p>So, I'm looking for a function that takes a <code>str</code> and optionally some hints and does its darndest to give me back a <code>unicode</code>. I could write one of course, but if such a function exists its author has probably thought a bit deeper about the best way to go about this.</p>
<p>I also know that Python's design prefers explicit to implicit and that the standard library is designed to avoid implicit magic in decoding text. I just want to explicitly say "go ahead and guess".</p>

269,093 | <p>I've a terrible memory. Whenever I do a CONNECT BY query in Oracle - and I do mean <em>every</em> time - I have to think hard and usually through trial and error work out on which argument the PRIOR should go.</p>
<p>I don't know why I don't remember - but I don't.</p>
<p>Does anyone have a handy memory mnemonic so I always remember ?</p>
<p>For example:</p>
<p>To go <strong>down</strong> a tree from a node - obviously I had to look this up :) - you do something like:</p>
<pre><code>select
*
from
node
connect by
prior node_id = parent_node_id
start with
node_id = 1
</code></pre>
<p>So - I start with a <code>node_id</code> of 1 (the top of the branch) and the query looks for all nodes where the <code>parent_node_id</code> = 1 and then iterates down to the bottom of the tree.</p>
<p>To go <strong>up</strong> the tree the prior goes on the parent:</p>
<pre><code>select
*
from
node
connect by
node_id = prior parent_node_id
start with
node_id = 10
</code></pre>
<p>So starting somewhere down a branch (<code>node_id = 10</code> in this case) Oracle first gets all nodes where the <code>parent_node_id</code> is the same as the one for which <code>node_id</code> is 10.</p>
<p><strong>EDIT</strong>: I <strong>still</strong> get this wrong so thought I'd add a clarifying edit to expand on the accepted answer - here's how I remember it now:</p>
<pre><code>select
*
from
node
connect by
prior node_id = parent_node_id
start with
node_id = 1
</code></pre>
<p>The 'english language' version of this SQL I now read as...</p>
<blockquote>
<p>In NODE, starting with the row in
which <code>node_id = 1</code>, the next row
selected has its <code>parent_node_id</code>
equal to <code>node_id</code> from the previous
(prior) row.</p>
</blockquote>
<p><strong>EDIT</strong>: Quassnoi makes a great point - the order you write the SQL makes things a lot easier.</p>
<pre><code>select
*
from
node
start with
node_id = 1
connect by
parent_node_id = prior node_id
</code></pre>
<p>This feels a lot clearer to me - the "start with" gives the first row selected and the "connect by" gives the next row(s) - in this case the children of node_id = 1.</p>

269,096 | <p>I'm trying to create a WSTransfer implementation (I realise Roman Kiss has written one already for WCF - but it doesn't actually meet the specifications)</p>
<p>I've ended up abandoning data contracts on the service contacts because WSTransfer is loosely coupled; so each the create message looks like Message Create(Message request).</p>
<p>This works fine, and everything is lovely until it's time to fire back a response.</p>
<p>The problem I have is in the way a WSTransfer response is constructed. Taking create as the example the response looks like</p>
<pre><code><wxf:ResourceCreated>
<wsa:Address>....</wsa:Address>
<wsa:ReferenceProperties>
<xxx:MyID>....</xxx:MyId>
</wsa:ReferenceProperties>
</wxf:ResourceCreated>
</code></pre>
<p>As you can see there are 3 different XML namespaces within the response message.</p>
<p>Now, it's easy enough when one is involved; you can (even if you're not exposing it), create a data contract and set the values and fire it back </p>
<pre><code>Message response = Message.CreateMessage(request.Version,
"http://schemas.xmlsoap.org/ws/2004/09/transfer/CreateResponse",
resourceCreatedMessage);
</code></pre>
<p>However the problem arises in setting different namespaces for the child elements within the response; it appears WCF's datacontracts don't do this. Even using</p>
<pre><code>[MessageBodyMember(Namespace="....")]
</code></pre>
<p>on the individual elements within the response class don't appear to make any changes, everything becomes part of the namespace specified for the contract class.</p>
<p>So how do I apply different namespaces to individual elements in a WCF Message; either via a contract, or via some other jiggery pokery?</p>

269,124 | <p>I am reading a binary log file produced by a piece of equipment. </p>
<p>I have the data in a byte[]. </p>
<p>If I need to read two bytes to create a short I can do something like this:</p>
<pre><code>short value = (short)(byte[1] << 8);
value += byte[2];
</code></pre>
<p>Now I know the value is the correct for valid data. </p>
<p>How would I know if the file was messed up and lets say the values FF FF were in those two places in the byte array?</p>
<p>When I look at the resultant value of converting FF FF to a short, I get a -1.</p>
<p>Is this a normal value for FF FF?, or did the computer just hit some kind of short bound and roll over with invalid data?</p>
<p>For my purposes all of theses numbers are going to be positive. If FF FF is actually a short -1, then I just need to validate that all my results are postitive. </p>
<p>Thank you,<br>
Keith</p>
<p><em>BTW, I am also reading other number data types. I'll show them here just because.
The Read function is the basic part of reading from the byte[]. All the other data type reads use the basic Read() function.</em></p>
<pre><code> public byte Read()
{
//advance position and then return byte at position
byte returnValue;
if (_CurrentPosition < _count - 1)
{
returnValue= _array[_offset + ++_CurrentPosition];
return returnValue;
}
else
throw new System.IO.EndOfStreamException
("Cannot Read Array, at end of stream.");
}
public float ReadFloat()
{
byte[] floatTemp = new byte[4];
for (int i = 3; i >= 0; i--)
{
floatTemp[i] = Read();
}
float returnValue = System.BitConverter.ToSingle
(floatTemp, 0);
if (float.IsNaN(returnValue))
{
throw new Execption("Not a Number");
}
return returnValue;
}
public short ReadInt16()
{
short returnValue = (short)(Read() << 8);
returnValue += Read();
return returnValue;
}
public int ReadInt32()
{
int returnValue = Read() << 24;
returnValue += Read() << 16;
returnValue += Read() << 8;
returnValue += Read();
return returnValue;

269,164 | <p>I am looking for an elegant solution for removing content from an ASP.Net page if no data has been set. Let me explain this a little more.</p>
<p>I have some blocks of data on a page that contain some sub-sections with individual values in them. If no data has been set for one of the values I need to hide it (so it does not take up space). Also, if none of the values within a sub-section have been set, it needs to be hidden as well. Finally if none of the sub-sections are visible within the block/panel, then I need to hide the entire thing.</p>
<p>The layout is implemented using nested Panels/DIVs</p>
<pre><code><Panel id="block">
<Panel id="sub1">
<Panel id="value1-1">blah</Panel>
<Panel id="value1-2">blah</Panel>
</Panel>
<Panel id="sub2">
<Panel id="value2-1">blah</Panel>
<Panel id="value2-2">blah</Panel>
</Panel>
</panel>
</code></pre>
<p>I am wondering if anyone has any decent ideas on implementing something like this without writing a bunch of nested <strong>If..Else</strong> statements, and without creating a bunch of custom controls. Whatever I implement needs to be robust enough to handle changes in the markup without constantly manipulating the codebehind.</p>
<p>I am hoping there is a way to do this through some simple markup changes (custom attribute) and a recursive function call on PageLoad or PreRender.</p>
<p>Any help is greatly appreciated.</p>
<h2>EDIT:</h2>
<p>Ok so what makes this tricky is that there might be other controls inside the sub-sections that do not factor into the hiding and showing of the controls. And each <em>value</em> panel could potentially have controls in it that do not factor into whether or not it is shown. Example:</p>
<pre><code><Panel id="sub2">
<Image id="someImage" src="img.png" />
<Panel id="value2-1">
<Label>blah</Label>
<TextBox id="txtValue" />
</Panel>
<Panel id="value2-2">blah</Panel>
</Panel>
</code></pre>
<p>This is an over simplified example, but not far off from what I have to worry about.</p>

269,179 | <p>I have a lot of spare intel linux servers laying around (hundreds) and want to use them for a distributed file system in a web hosting and file sharing environment. This isn't for a HPC application, so high performance isn't critical. The main requirement is high availability, if one server goes offline, the data stored on it's hard drives is still available from other nodes. It must run over TCP/IP and provide standard POSIX file permissions.</p>
<p>I've looked at the following:</p>
<ul>
<li><p>Lustre (<a href="http://wiki.lustre.org/index.php?title=Main_Page" rel="noreferrer">http://wiki.lustre.org/index.php?title=Main_Page</a>): Comes <em>really</em> close, but it doesn't provide redundancy for data on a node. You must make the data HA using RAID or DRBD. Supported by Sun and Open Source, so it should be around for a while</p></li>
<li><p>gfarm (<a href="http://datafarm.apgrid.org/" rel="noreferrer">http://datafarm.apgrid.org/</a>): Looks like it provides the redundancy but at the cost of complexity and maintainability. Not as well supported as Lustre.</p></li>
</ul>
<p>Does anyone have any experience with these or any other systems that might work?</p>

<ol>
<li>The first downside to changing that
I see is the cost. No matter what
the charges for the application
server, Tomcat is free.</li>
<li>Second is the complexity. We don't
use either EJB nor EAR features (of
course not, we can't), and have not missed them.</li>
</ol>
<p>What then are the benefits I'm not seeing?</p>
<p>What are the drawbacks that I haven't mentioned?</p>
<hr>
<p>Mentioned were...</p>
<ol>
<li>JTA - Java Transaction API - We
control transaction via database
stored procedures.</li>
<li>JPA - Java Persistence API - We use
JDBC and again stored procedures to
persist.</li>
<li>JMS - Java Message Service - We use
XML over HTTP for messaging.</li>

269,193 | <p>I've got two ListBox'es that are databound to the same BindingList.</p>
<p>The issue is that when changing the selected item from the GUI it's changing the position in the BindingList and then the BindingList signals the other ListBox to change its selected item.</p>
<p>So I've got the two ListBoxes Selected Item also synchronized which is not good for me.</p>
<p>I'd like to maintain the list of items in sync. without the cursor position.</p>
<p>How do I disable that cursor so it's not maintained?</p>
<p>sample code (just add two ListBoxes to the Form at design time and register the SelectedIndexChanged events and register the button click event with a button):</p>
<pre><code>public partial class Form1 : Form
{
BindingList<string> list = new BindingList<string>();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
list.Add("bla1");
list.Add("bla2");
list.Add("bla3");
this.listBox1.DataSource = list;
this.listBox2.DataSource = list;
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (listBox1.SelectedIndex != -1)
System.Diagnostics.Trace.WriteLine("ListBox1: " + listBox1.SelectedItem.ToString());
}
private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
{
if (listBox2.SelectedIndex != -1)
System.Diagnostics.Trace.WriteLine("ListBox2: " + listBox2.SelectedItem.ToString());
}
// Register this event to a button
private void button1_Click(object sender, EventArgs e)
{
list.Add("Test");
}
}

269,207 | <p>I have implemented a SAX parser in Java by extending the default handler. The XML has a ñ in its content. When it hits this character it breaks. I print out the char array in the character method and it simply ends with the character before the ñ. The parser seems to stop after this as no other methods are called even though there is still much more content. ie the endElement method is never called again. Has anyone run into this problem before or have any suggestion on how to deal with it?</p>

269,212 | <p>We have an Java application running on Weblogic server that picks up XML messages from a JMS or MQ queue and writes it into another JMS queue. The application doesn't modify the XML content in any way. We use BEA's XMLObject to read and write the messages into queues.</p>
<p>The XML messages contain the encoding type declarations as UTF-8.</p>
<p>We have an issue when the XML contains characters that are out side the normal ASCII range (like £ symbol for example). When the message is read from the queue we can see that the £ symbol is intact, however once we write it to the destination queue, the £ symbol is lost and is replaced with £ instead.</p>
<p>I have checked the OS level settings (locale settings) and everything seems to be fine. What else should I be checking to make sure that this doesn't happen?</p>

269,223 | <p>As I understand, the pimpl idiom is exists only because C++ forces you to place all the private class members in the header. If the header were to contain only the public interface, theoretically, any change in class implementation would not have necessitated a recompile for the rest of the program. </p>
<p>What I want to know is why C++ is not designed to allow such a convenience. Why does it demand at all for the private parts of a class to be openly displayed in the header (no pun intended)?</p>

269,241 | <p>I have a not-so-small class under development (that it changes often) and I need not to provide a public copy constructor and copy assignment.
The class has objects with value semantics, so default copy and assignment work.</p>
<p>the class is in a hierarchy, with virtual methods, so I provide a virtual Clone() to avoid slicing and to perform "polymorphic copy".</p>
<p>I don't want to declare copy assignment and construction protected AND to define them (and to maintain in-sync with changes) unless I have some special thing to perform.</p>
<p>Do someone knows if there's another way?</p>

269,263 | <p>I have just been getting into low level programming (reading/writing to memory that sort of thing) and have run into an issue i cannot find an answer to.</p>
<p>The piece of information i want to read from has an address that is relative to a DLL loaded in memory e,g, it is at mydll.dll + 0x01234567. the problem im having is that the dll moves around in memory but the offset stays the same. Is there anyway to find out the location of this dll in memory.</p>
<p>I am currently trying to do this preferably in c# but i would be grateful for help in most highish level languages.</p>

269,267 | <p>Excel has a Conditional Formatting... option under the Format menu that allows you to change the style/color/font/whatever of a cell depending upon its value. But it only allows three conditions.</p>
<p>How do I get Excel to display say, six different background cell colors depending upon the value of the cell? (IE Make the cell red if the value is "Red", and blue if "Blue" etc.)</p>

269,268 | <p>I'd like to implement a big int class in C++ as a programming exercise—a class that can handle numbers bigger than a long int. I know that there are several open source implementations out there already, but I'd like to write my own. I'm trying to get a feel for what the right approach is.</p>
<p>I understand that the general strategy is get the number as a string, and then break it up into smaller numbers (single digits for example), and place them in an array. At this point it should be relatively simple to implement the various comparison operators. My main concern is how I would implement things like addition and multiplication.</p>
<p>I'm looking for a general approach and advice as opposed to actual working code.</p>

269,298 | <p>I have a list of items that I am displaying in a floated list, with each item in the list at a fixed width so that there's two per row. What is the best practice to prevent this horrible thing from happening:</p>
<p><a href="http://x01.co.uk/floated_items.gif">alt text http://x01.co.uk/floated_items.gif</a></p>
<p>Possibilites:</p>
<ul>
<li>Trim to a specified number of characters before displaying the data. Requires guesswork on how many characters will be "safe".</li>
<li>Overflow: hidden. Hacky.</li>
<li>Remove the background and just have a top border on each item.</li>
</ul>
<p>Possible but silly:</p>
<ul>
<li>Have a scrollbar in each item by doing overflow: auto, this will look horrendous.</li>
<li>Add a background image to the container. It's not guaranteed that there's always an equal number of items so this option is out.</li>
</ul>
<p>Any help on this irritating issue appreciated!</p>

269,314 | <p>On Linux (or Solaris) is there a better way than hand parsing <code>/proc/self/maps</code> repeatedly to figure out whether or not you can read, write or execute whatever is stored at one or more addresses in memory?</p>
<p>For instance, in Windows you have <code>VirtualQuery</code>. </p>
<p>In Linux, I can <code>mprotect</code> to change those values, but I can't read them back.</p>
<p>Furthermore, is there any way to know when those permissions change (e.g. when someone uses <code>mmap</code> on a file behind my back) other than doing something terribly invasive and using <code>ptrace</code> on all threads in the process and intercepting any attempt to make a <code>syscall</code> that could affect the memory map?</p>
<p><strong>Update:</strong></p>
<p>Unfortunately, I'm using this inside of a JIT that has very little information about the code it is executing to get an approximation of what is constant. Yes, I realize I could have a constant map of mutable data, like the vsyscall page used by Linux. I <em>can</em> safely fall back on an assumption that anything that isn't included in the initial parse is mutable and dangerous, but I'm not entirely happy with that option.</p>
<p>Right now what I do is I read <code>/proc/self/maps</code> and build a structure I can binary search through for a given address's protection. Any time I need to know something about a page that isn't in my structure I reread /proc/self/maps assuming it has been added in the meantime or I'd be about to segfault anyways.</p>
<p>It just seems that parsing text to get at this information and not knowing when it changes is awfully crufty. (<code>/dev/inotify</code> doesn't work on pretty much anything in <code>/proc</code>)</p>

<li>on my local machine I can access the project at <a href="http://myproject" rel="noreferrer">http://myproject</a></li>
<li>others on my local network can access the project at my.ip.address/myproject</li>
<li>keep localhost pointing to the xampp's htdocs folder so I can easily add other projects.</li>
</ol>
<p>I've got 1 & 2 working by editing the windows hosts file, and adding a virtual directory in xampp's apache\conf\extra\httpd-vhosts.conf file. I don't immediately see how to do 3 without messing up 4.</p>

269,363 | <p>I have written a windows service using the Apache.NMS and Apcahe.NMS.ActiveMQ (version 1.0) libraries. The service consumes messages from ActiveMQ from a vendor server.</p>
<p>The service spins up a connection and listens for messages (I handle the OnMessage event)</p>
<p>The connection is a transacted connection so I call commit after each message.</p>
<p>When the service starts up, everything works very well and does so for a while. However, after it has run for a while, it will no longer consume messages. Even if I reset the service. It usually takes a restart of my service AND the vendor server (tomcat) to get things going again. The vendor insists that nothing is wrong on their side.</p>
<p>No exceptions are thrown on either side (client or server) - it's just 'stuck'.</p>
<p>Should I consider using Spring.Messaging.Nms? </p>

<p>I tried following the access listed in the <a href="http://httpd.apache.org/docs/2.0/platform/windows.html" rel="nofollow noreferrer">official documentation</a>, but it seems to require more access. <strong>Does anyone know what access Apache 2.0 needs to start as a service?</strong></p>

<p>I also checked the syntax of the configuration file from command-line using the <strong>-t</strong> parameter, but I received the message <strong>Syntax OK</strong>.</p>
<p>Here's the error I get when starting as a service from command-line:</p>

The Apache2 service is starting.
The Apache2 service could not be started.
A service specific error occurred: 1.

269,408 | <p>We have Core2 machines (Dell T5400) with XP64.</p>
<p>We observe that when running 32-bit processes,
the performance of memcpy is on the order of
1.2GByte/s; however memcpy in a 64-bit process
achieves about 2.2GByte/s (or 2.4GByte/s
with the Intel compiler CRT's memcpy). While the
initial reaction might be to just explain this
away as due to the wider registers available
in 64-bit code, we observe that our own memcpy-like
SSE assembly code (which should be using 128-bit
wide load-stores regardless of 32/64-bitness of
the process) demonstrates similar upper limits on
the copy bandwidth it achieves.</p>
<p>My question is, what's this difference actually
due to ? Do 32-bit processes have to jump through
some extra WOW64 hoops to get at the RAM ? Is it something
to do with TLBs or prefetchers or... what ?</p>
<p>Thanks for any insight.</p>
<p>Also raised on <a href="http://software.intel.com/en-us/forums/intel-avx-and-cpu-instructions/topic/63277/" rel="noreferrer">Intel forums</a>.</p>

Is it possible to do this, or would it require for the image to be added into the canvas as a child? That would not work with this program as all children of the canvas are handled differently.</p>
<p>Thank You</p>

269,440 | <p>I have the following query:</p>
<pre><code>UPDATE lessonstatus
INNER JOIN user ON lessonstatus.user_id = user.user_id
SET user_id = (SELECT user_id FROM user WHERE username = 'too_many_accounts')
WHERE last_name = 'stupid'
AND first_name = 'user'
AND username != 'too_many_accounts'
AND lessonstatus.lesson_id NOT IN (SELECT lesson_id FROM lessonstatus WHERE user_id = 1);
</code></pre>
<p>However, I get the following error when trying to execute it:</p>
<pre><code>Error Code : 1093
You can't specify target table 'lessonstatus_rtab' for update in FROM clause
</code></pre>
<p>How would I fix this query so that it works?</p>

269,456 | <p>We are rolling out a site for a client using IIS tomorrow. </p>
<p>I am to take the site down to the general public (Sorry, we are updating message) and allow the client to test over the weekend after we perform the upgrade.</p>
<p>If it is successful, I open it to everbody - if not, I rollback.</p>
<p>What is the easiest way to put a "We're not open" sign for the general public, but leave the rest open to testers?</p>

269,458 | <p>Ages ago when I was a java developer I could make separate ant scripts that I would call from my main ant script. I would put properties unique to each environment where my main script would run. I want to do the same thing in MSBuild but I can't find out how to chain MSBuild scripts together.</p>

269,462 | <p>I'm doing some small changes to C++ MFC project. I'm .NET developer so Windows programming is new to me.</p>
<p>I need to launch some method right after CDialog is completely shown (painted) for the first time, but only once.</p>
<p>How can I do this? In .NET I would handle <strong>Form.Shown</strong> event.</p>
<p>Do I need to handle some message? Which?
Do I need to override some CDialog method?
Or is there no easy way? I'm thinking of handling WM_ACTIVATE and then using a flag to ensure I call another method only once.</p>
