• talshac Problem deploying a VC++ application

  Hi all.. I have programmed a small application (a Win32 type application) that uses only Windows API and some CRT functions. That way, I thought it would have the fewest dependencies as possible, but I'm afraid I was wrong. First, I only copied the released EXE file to the target machine.

I am able to access this from a C++ .net program, but not from a C# program using P/Invoke. It seems that a plain MFC DLL is not "good enough" for use with DllImport.

That's what providing definitions for AllocStdCallThunk and FreeStdCallThunk does for you. ...Show All
