• .NET Development Timeout expired.

  I'm getting this error intermittently when execting a sql command. I tried increasing the timeout property of the command object, but sometimes I still get the error. Other appplications may be acessing the same tables. Is there a way to prevent the error System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. looks ok. Try removing the connection timeout property in the connectionstring. What happens now also where is the server located Just a minor refactor of code.... SqlConnection Connection = new SqlConnection ( "user id=user;" + "password=password;" + "server=serve ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Suggestion for stock Vertex structs

  I notice that the framework provides a few stock vertex structures like VertexPositionColor etc. This is cool but it would be great if these could inherit from an interface which provides a mechanism to get the SizeInBytes and Element information abstractly. These structs currently provide this information as static properties but this is no good if you are are trying to write a generic function that can deal with a number of different types of vertex structures seamlessly. My suggestion is that in future something like an IVertexInfo is provided that lets you deal with these concrete vertex structures abstractly.  Perhaps something like this. interface IVertexInfo {     VertexElement [] Elemen ...Show All

• SQL Server Report Manager not responding

  Hi, I'm hoping to get some help here. I've spend countless hours trying to get Reporting Services running without success. When I run the Report Manager it does not respond. Coming up with Opening page http://localhost/reports/Pages/Folder.aspx . . . The progress bar ticks along but the page never actually loads. The Configuration tool shows green icons everywhere.

What else is involved I have loaded Service Pack 1 and the latest hotfixes. What else can I try Thanks in advance, Claude It looks lik ...Show All

• .NET Development configSource - share connection strings file across web-services ?

  We wish to have a single (external) config file that stores database connection strings, shared across a number of web-services that all connect to the same database. This would allow a connection string to be changed in a single file that then applies to all relevant web-services. Possibilities include the .NET configSource, or EntLib 2.0's "File Configuration Source" (I'm using Data Access block). But I believe that .NET 2.0 only allows configSource to be in a relative sub-directory, and can't access relative parent directories, so this wouldn't work for sharing a config file across web-services At least that's what this post suggests: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=146960&SiteID=1 Does .NET ...Show All

• Software Development for Windows Vista Page Limit?

  Does anyone know whether there is a page limit in an XPS document I have created a 10,000 page XPS document printed with the Microsoft XPS Document Writer from Crystal Reports XI. I can open this document in the XPS viewer with no problems. However, when I create a 100,000 page document using the same package, the XPS document does not open in the XPS viewer and the memory use on my computer jumps and keeps on rising. I am working on Windows XP. Any ideas, anyone did you also see that massive memory usage when printing your 10,000 page XPS file I have tried to print 5,000-10,000 Visuals via the Visuals-batchwriter and I've got ~2gig of swapfile size and ~1gig for the process... and it got slower a ...Show All

• Internet Explorer Development IE7 Invalid URL error

  I am currently getting an "Invalid URL" message in IE7. The URL in question is: SWERowId=1-QYTXL&SWETime=&SWEMethod=Save&SWEReqRowId=1&SWEApplet=AMP+Outstandings+Reply+For+PAR+Applet&SWEView=AMP+CSA+Outstanding+Reply+View+(SCW)&SWEApcnt=4&SWECmd=InvokeMethod&SWECount=4&SWERowIds=") I did not get this error in IE6 so it seems as if IE7 does further checking on invalid characters within the URL. Are there any settings in IE7 that can prevent this check from happening Thanks ...Show All

• Visual Studio Locking the solution explorer for update?

  Hi. I need to perform a lot of file manipulation (code generation) in an add-in. I think the solution explorer's treeview refreshing is causing me some problems. On some odds occurances, a stressed file (write operations) will become locked by another process. This doesn't seem to be a problem with the other files since they aren't as stressed as this one. Is there a way to call a BeginUpdate() on the solution explorer You will need to get to the IVsLiteTree interface of the solution explorer window. Once you have that, you can call the SetRedraw or DelayRedraw methods to control when the tree will redraw its self. Craig ...Show All

• Visual Basic Find what server a DFS link points to.

  I am writing a script to find out where a user is logged in. the script first looks at the users profile path and then passes that to code which queries LanManServer that the users profile is on for the sessions and looks for the users session on there. But this does not work with the DFS path i need to be able to convert the DFS path to the Server and share that it is on. Please help.

• Visual C++ Linker error porting an NT service from VC 6.0 to VC 8.0 - using a makefile

  I am trying to port a service from VC 6.0 to VC 8.0. My VC 6.0 service was compiled from the commandline using a makefile. I created a Makefile project in VC 8.0.

• Visual Studio Cannot debug MFC source after upgrading to VS 2005 SP1 using symbol server

  I have VS 2005 and SP 1 installed and have enabled the symbol server in "Tools -> Options -> Debugging -> Symbols". It is no longer possible to step into MFC source code when debugging an MFC application. This used to work with VS 2005 without SP1. The only workaround to my knowledge is to disable the symbol server. Then the .pdb from the symbol server will not be used. If I understand this correctly. the .pdb from the symbol server (http://msdl.microsoft.com/download/symbols) now has source information stripped and so will prevent stepping into MFC source with the debugger. Thank you! Yes, that works like a charm. I had to delete all files from the symbol cache first. ...Show All
