• Visual C++ How to do Unit Test for Visual C++ unmanaged code with Visual Studio 2005?

  I got the following words in MSDN Library,  "If your production code is unmanaged, it needs to be callable from a static library, an .obj file, or a DLL entry point. Class methods that are embedded inside an executable file or a DLL will not work because unmanaged Visual C++ does not offer the runtime discovery mechanism, reflection. Therefore, only the traditional native binding mechanisms will work. " Does this mean we still cannot do uni ...Show All

• Visual Studio Team System Error loading Event Web Services

  We are getting this at the very end of the TF Server Beta 3 install.  From reading various posts, it seems that you have to name the special account TFSSETUP exactly that "TFSSETUP" even though the docs indicate that you can pick an arbitrary name.  Can someone from the TF team confirm that this is indeed a bug   We will most likely have different TF servers running in different divisions and I can see problems if everyone ha ...Show All

• Smart Device Development Porting app with CEditView

  I had an application that used a CEditView running on PPC 2003. I am porting this app to WM v5. Since CEditView has disappeared from VS 2005, I've had to implement a workaround. I am using a CView that instantiates a CEdit. This appears to work except I have to handle the Cut and Copy actions in my view class and call the CEdit's Cut and Copy methods. This seems to work well. I am having problems with the ID_FILE_SAVE and ID_FILE_SAVEA ...Show All

  I've got a couple of scenarios to bring up regarding errors we are seeing after using the VSTO 2005 tools after previously having these solutions run under VSTO 2003: 1.
