Why AfxGetResourceHandle causes Asserts?

Why AfxGetResourceHandle causes Asserts?

  You probably need this :

  AFX_MANAGE_STATE(AfxGetStaticModuleState( ));

  before you invoke the MFC DLL method.

  My scenario is somehow complicated but I try to simplify it: I have a CLR class libraray that wrapps some functionalities of a MFC dll. The MFC dll has a class with a method that calls AfxGetResourceHandle() method, when I use the corresponding method on the wrapper the Asserts are generated. The method is trying to get a handle of a resource that is defined inside the MFC dll, why I got asserts ..\Microsoft Visual Studio 8\VC\atlmfc\include\afxwin1.inl _AFXWIN_INLINE HINSTANCE AFXAPI AfxGetInstanceHandle() { ASSERT(afxCurrentInstanceHandle != NULL); return afxCurrentInstanceHandle; }

  Ah, then it looks like you just need some #include's in your stdafx.h to be able to use AFX_MANAGE_STATE.

  When you enable "using MFC in a shared DLL", the header files are not automatically inserted for you. Create a fresh MFC app, and copy/paste the MFC header files, and you should be okay.

  The managed method that is calling the MFC dll is a method of a class that inherits

  MarshalByRefObject. Could I have both of these in a MFC dll with /clr enabled

  That shouldn't cause any problems as far as I can tell.

  I'm invoking the method from a mixed assembly, and I'm a C# programmer not familiar with c++ includes. When I add this line, it complains that these are undeclared. Do I need to include something before calling this

  If the DLL is an MFC extension DLL, then you cannot use it from a non-MFC caller. Which means your mixed mode DLL must be an MFC regular DLL with /clr enabled. Is that the case here
