• Visual Studio 2008 (Pre-release) WCF method returning a strongly typed collection to a .NET 2.0 client

  Ok I have a WCF method defined which returns a strongly typed collection. [ServiceKnownType(typeof(XXX.Platform.RoleAssignment))] XXX.Platform.RoleAssignmentCollection GetRoleAssigments(int UserID); RoleAssignmentCollection class can add objects of type XXX.Platform.RoleAssignment.

• Visual C++ Number of sub-threads are increasing when OpenMP is used in a spawned Win32 thread...

  OpenMP support in VS2005 is very nice feature, and our team is now using it intensively. However, we've found a very big problem in OpenMP that the number of threads are increasing. When using OpenMP in VS2005, the created sub-threads still remains even if the parallel-construct finished. In usual cases, it would not be so problematic since the reamaining sub-threads are re-used when another OpenMP parallel construct enters into action. However, when we use the OpenMP funcion in a spawnd Win32 thread, the remaining sub-threads are not re-used. Here is an example to reproduce it: static WorkerThread( LPVOID ) { ::omp_set_num_threads( 4 ); #pragma omp parallel { TRACE( _T("Thread Id: %d\n"), ::GetCurrentThreadId() ); ...Show All

• Visual Studio Team System Standard team project reports have empty parameter combos

  Hi, I created a new team project last week, but noticed that when I went to (for example) the "Remaining Work" report, the Iteration combo was blank, and when dropped down didn't contain any entries. I tried forcing a process of the data warehouse, but that didn't help. Also, parameter in other reports displayed the same issue (eg, Work Item Type, Area, etc) Today I tried deleting the project and creating it again, but it's made no difference. All the other projects that already existed on the server behave without a problem. It may be relevant that this is almost certainly the first project created since we moved from the RC to the release version. This project is going live tomorrow, so I could really do wit ...Show All

• .NET Development How to sign an assembly that is already compiled?

  I am building an application in 1.1, and all the assemblies in my application are strongly named. I want to reference an external assembly that is not strongly named/signed from one of my strongly named assemblies. The build in VS fails because strongly named assembly cannot reference weakly named assemblies. I do not have the source code for the weakly named assembly. What are my options Can I sign the weakly-named assembly using any tool so that it can have a strong name. Thanks. I remember this problem bitting me as well :) You can try ILMerge tool (you can download it from http://www.microsoft.com/downloads/details.aspx familyid=22914587-b4ad-4eae-87cf-b14ae6a939b0&displaylang=en ).

• Visual C++ Visual Studio 2005 relative paths

  Hello folks I know this is a litlle bit unusual question, but I just installed visual studio 2005 and my converted solutions from 2003 are fine. But when I create a new project using 2005, my additional include directories are messed up. I cannot use relative paths anymore and instead of showing relative paths from my project, it shows the Visual Studio path, i.e : .\1033\..... Btw, the relative paths created in the converted solutions are ok. Anyone had the same problem Thanks in advance In Visual Studio 2005 you will have to hard code alot of the paths you didn't before, I think.... I just always have my includes in the default directory with the rest so I don't have to worry about situations like that. ...Show All

• Visual Basic Checking if drive exist

  I got a few questions, maybe you might be able to help. I am needing to design a program that will check for a problem with another pc in my local network. We are not running a server type enviroment, but just a simple peer to peer platform. Any how on to the problem, We use one pc to act as a server, and the hard drives use a raid controller using 1(mirror). We ran into a snaffou yesterday, because no one in that building monitors thier pc's, they just use them, anyhow the raid broke and created 2 independent drives with the same shared folders, and the drive windows decided was bad wasnt the right drive, it renamed the volume and took everyone back to fridays data that resided on the drive that windows thought was bad.

• Windows Forms How to bind a hierarchical DataSet
