I want to create a console application, but I would also like to use some of the features that are in MFC.

I linked my console app with #include <afx.h> and calls to MFC classes successfully. However on run, it crashes immediately (before even my main() function). I think I recall something about winmain()? ??

I'm running one now by including stdafx.h in the main cpp file.  Do not use winmain() for your main program use main().

Make sure to add a stdafx.cpp to the project and link it in.  My stdafx.cpp only has one line.

#include "stdafx.h"

My stdafx.h looks like this

// stdafx.h : include file for standard system include files,
//  or project specific include files that are used frequently, but
//      are changed infrequently
//

#if !defined(AFX_STDAFX_H__791E939E_5C6B_11D2_9423_080009ACC8C1__INCLUDED_)
#define AFX_STDAFX_H__791E939E_5C6B_11D2_9423_080009ACC8C1__INCLUDED_

#if _MSC_VER >= 1000
#pragma once
#endif // _MSC_VER >= 1000

#define VC_EXTRALEAN            // Exclude rarely-used stuff from Windows headers

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxdisp.h>        // MFC OLE automation classes
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>                  // MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT


// This macro is the same as IMPLEMENT_OLECREATE, except it passes TRUE
//  for the bMultiInstance parameter to the COleObjectFactory constructor.
//  We want a separate instance of this application to be launched for
//  each OLE automation proxy object requested by automation controllers.
#ifndef IMPLEMENT_OLECREATE2
#define IMPLEMENT_OLECREATE2(class_name, external_name, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8) \
      AFX_DATADEF COleObjectFactory class_name::factory(class_name::guid, \
            RUNTIME_CLASS(class_name), TRUE, _T(external_name)); \
      const AFX_DATADEF GUID class_name::guid = \
            { l, w1, w2, { b1, b2, b3, b4, b5, b6, b7, b8 } };
#endif // IMPLEMENT_OLECREATE2

//{{AFX_INSERT_LOCATION}}
// Microsoft Developer Studio will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_STDAFX_H__791E939E_5C6B_11D2_9423_080009ACC8C1__INCLUDED_)

Thanks for the reply. I just tried it, by copying your stdafx.h file and making a stdafx.cpp file as you say. So, my project has 2 files, main.cpp and stdafx.cpp . Some reason, that didn't work.  By compiling the stdafx.h or main.cpp, I get 22 errors that are in the .h file.

What kind of project workspace should I have? Win32 Console Application, MFC AppWizard, or other? Currently, i have console app. MFC AppWizard seems like it'll only make GUI apps...

Thanks,
Tom

1) Change the selection in the Project Settings/General/Microsoft Foundation Classes list box to Use MFC in a Shared DLL (that is what I have used, and I know it's work).

2) Write the following skeletal code:

#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers

#include <afxwin.h>
#include <afxext.h>

#include <iostream.h>

// #include any other headers necessary

CWinApp theApp; // Just to keep certain MFC classes happy.

int main()
{
   if (!::AfxWinInit((::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
   {
      cerr << "Can not initialize MFC!" << endl;
      return EXIT_FAILURE;
   }

   CWnd wndMain; // Dummy CWnd to keep certain MFC classes happy.
   theApp.m_pMainWnd = &wndMain;

   ... // Use any MFC classes (except CWnd, and derivatives).

   return EXIT_SUCCESS;
}
