建立一个Win32空项目后，然后手工打造的最简单的MFC程序：
1: //stdafx.h
2: #pragma once
3: #include <sdkddkver.h>
4: #include <afxwin.h>
5: #include <afxwinappex.h>
6: #include <afxframewndex.h> 1: //stdafx.cpp
2: #include "stdafx.h" 1: //MainApp.h
2: #pragma once
3: class CMainApp : public CWinAppEx
4: {
5: public:
6: virtual BOOL InitInstance();
7: }; 1: //MainApp.cpp
2: #include "stdafx.h"
3: #include "MainApp.h"
4: #include "MainWindow.h"
5:
6: CMainApp mianApp;
7:
8: BOOL CMainApp::InitInstance()
9: {
10: CWinAppEx::InitInstance();
11:
12: SetRegistryKey(TEXT("Hello MFC app.")); [NextPage] 13:
14: m_pMainWnd = new CMainWindow();
15: m_pMainWnd->ShowWindow(SW_SHOW);
16: m_pMainWnd->UpdateWindow();
17: return TRUE;
18: } 1: //MainWindow.h
2: #pragma once
3: class CMainWindow : public CFrameWndEx
4: {
5: public:
6: CMainWindow(void);
7:
8: DECLARE_MESSAGE_MAP()
9:
10: afx_msg void OnPaint();
11: afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
12: }; 1: //MainWindow.cpp
2: #include "stdafx.h"
3: #include "MainWindow.h"
4:
5: CMainWindow::CMainWindow(void)
6: {
7: Create(NULL,TEXT("Main window")); [NextPage] 8: }
9:
10: BEGIN_MESSAGE_MAP(CMainWindow, CFrameWndEx)
11: ON_WM_PAINT()
12: ON_WM_LBUTTONDOWN()
13: END_MESSAGE_MAP()
14:
15: void CMainWindow::OnPaint()
16: {
17: CPaintDC dc(this); // device context for painting
18: // TODO: Add your message handler code here
19: CRect rc;
20: GetClientRect(&rc);
21: dc.DrawText(TEXT("It is a simple MFC application!"),&rc,DT_VCENTER|DT_SINGLELINE|DT_CENTER);
22: }
23:
24: void CMainWindow::OnLButtonDown(UINT nFlags, CPoint point)
25: {
26: // TODO: Add your message handler code here and/or call default
27: AfxMessageBox(TEXT("Left mouse button clicked!"));
28: CFrameWndEx::OnLButtonDown(nFlags, point);
29: }
