I'm using VC++6 and I've created MFC dialog,and now I want to add functionallity.

I have 3 classes already made,but cant add them to project and compile.

I've added files in file view and included .h files in stdafx.h and here is what I get:

Code:
#if !defined(AFX_STDAFX_H__6BF529B9_3795_4AE3_9A72_3FADC2FA5C53__INCLUDED_)
#define AFX_STDAFX_H__6BF529B9_3795_4AE3_9A72_3FADC2FA5C53__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 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

//========================================

#include <Main.h> // I INCLUDED 3 HEADERS HERE
#include <Mail.h>
#include <Mail1.h>

//========================================

//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_STDAFX_H__6BF529B9_3795_4AE3_9A72_3FADC2FA5C53__INCLUDED_)

here's the error:

Code:
fatal error C1083: Cannot open include file: 'Main.h': No such file or directory
I copied .h and .cpp files in project directory.
