AfxGetApp()->m_pMainWnd in a DLL? [Edit]
-
Hello, I am currently writing a wrapper DLL in VC++ 6 so that I can use specific SDK functions from VB .Net. (VB .Net can access the function through "Private Declare Function GetDuration Lib "Path\Wrapper.dll" (parameters)") In my C++ DLL I need to pass an "HWND" value to an SDK function; however, when I use "AfxGetApp()->m_pMainWnd" the compiler returns two errors:
'AfxGetApp' undeclared identifier left of '->m_pMainWnd' must point to struct/class/unionAm I trying to retrieve my DLL's "HWND" correctly or is there a better function than "AfxGetApp()" to use in a DLL? [Edit] If I use "AfxGetMainWnd()" instead, I only get one error:'AfxGetMainWnd' undeclared identifierI am unsure why it says that "AfxGetMainWnd" is an undeclared identifier.
