MFC linker error LNK1120???

[cstudent]

I've got another problem with visual studio 05 and trying to program in MFC!!
First problem is solved in the link below:
http://www.cplusplus.com/forum/windows/9225/

But now as i've tried to link to it i'm getting the following linker error
fatal error LNK1120

//this is the file lab9.cpp
#include "lab9.h"

//define our window constructor
COurWin::COurWin()
{
	//Call CframWnd's creator() function
	Create(NULL, TEXT("my_window") );
}

BOOL COurApp::InitInstance()
{
	m_pMainWnd = new COurWin;
	m_pMainWnd->ShowWindow(m_nCmdShow);
	m_pMainWnd->UpdateWindow();
	return TRUE;
}

BEGIN_MESSAGE_MAP(COurWin, CFrameWnd)
END_MESSAGE_MAP()

COurApp App;

my header file

// This is the file lab9.h 
// Include standard windows functions and classes 
#include <afxwin.h> 
// We always derive classes from the main MFC classes 
// Derive main window class 

class COurWin:public CFrameWnd 
{ 
// We shall want control over construction 
public: 
	COurWin(); 

	// We must declare the message map - no semi-colon 
	DECLARE_MESSAGE_MAP() 
}; 

// Derive application class 
class COurApp : public CWinApp 
{ 
	// We need to override InitInstance() 
	BOOL InitInstance(); 
};

cheers guys

You need to post the full error message, including all the unresolved externals that the linker is complaining about.
