最简单的MFC程序

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."));

 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"));

  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: }
