    I have a dialog with just one button on it.

    Code:
    #include "stdafx.h"
    
    #include "resource.h"
    #include "FrmMain.h"
    
    
    int APIENTRY WinMain(HINSTANCE hInstance,
                         HINSTANCE hPrevInstance,
                         LPSTR     lpCmdLine,
                         int       nCmdShow)
    {
     	CFrmMain d;
    	d.DoModal();
    
    	return 0;
    }
    In the stdafx.h file I have this in it.

    Code:
    #if !defined(AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_)
    #define AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_
    
    #if _MSC_VER > 1000
    #pragma once
    #endif // _MSC_VER > 1000
    #define VC_EXTRALEAN
    //#define WIN32_LEAN_AND_MEAN		// Exclude rarely-used stuff from Windows headers
    
    //#include <windows.h>
    #include <afxwin.h>         // MFC core and standard components
    #include <afxext.h>         // MFC extensions
    #include <afxdisp.h>        // MFC Automation classes
    #include <afxdtctl.h>		// MFC support for Internet Explorer 4 Common Controls
    #ifndef _AFX_NO_AFXCMN_SUPPORT
    #include <afxcmn.h>			// MFC support for Windows Common Controls
    #endif // _AFX_NO_AFXCMN_SUPPORT
    
    
    
    // TODO: reference additional headers your program requires here
    
    //{{AFX_INSERT_LOCATION}}
    // Microsoft Visual C++ will insert additional declarations immediately before the previous line.
    
    #endif // !defined(AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_)
    And this is the errors that I get;

    c:\program files\microsoft visual studio\myprojects\test\test2\frmmain.cpp(52) : fatal error C1010: unexpected end of file while looking for precompiled header directive

    Any one know how to fix the problems?

    Thanx in advance!

    Post Maybe you should ...

    I am thinking you need to "#include" the "stdafx.h" header file to the dialog class's source/header file.

    Code:
    // In CFrmMain.h
    #include "stdafx.h"
    
    ///////////////////////////
    /* Other stuff here */
    ///////////////////////////
    Code:
    // In CFrmMain.cpp
    #include "stdafx.h"
    
    ///////////////////////////
    /* Other stuff here */

    Thanx. That worked. But then other problems came;

    Code:
    nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
    nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
    Debug/test3.exe : fatal error LNK1120: 2 unresolved externals
    How can I fix those errors?

    Thanx in advance!

    Thank you very much! I finaly got it to work. This is the first forum that helped me this much in C++. I have another question. How do I start a class. I know I have to first declare a variable of a class and then create and instance. I think that is how to do it but Im not sure. Could someone please direct me to the correct way to start this?

    Thanx in advance!

    In my opinion, the correct way to start is with a good book.
