• jy_lam What will cause AfxGetModuleState() return different values during DLL initialization?

  My application has over 100 Dlls. During startup, many resources failed to be found. I finally find out this is because AfxGetModuleState() returns different values in the CDynLinkLibrary's constructor, but I get no idea how can this happen. Anybody can help Thanks. AFX_MANAGE_STATE(AfxGetModuleState( )) is redundant, as you're telling MFC to context-switch to the context it's already in. I would try to tro ...Show All

• Pradeep T How to link to the correct STL library when a third party dll is based on VC6?

  I have a third party dll targeted for VC6 and .net 2003. It worked well with my old MFC application. After it was migrated to VC 2005, it throws an exception of access violation whenever the stl string information in the object is accessed. Accessing other members of the object is OK. I guess it might be linked to the stl.net library instead of the old stl library that the dll is based on. Anyone knows what is the problem  and how it c ...Show All
