MFC学习笔记3引用资源

#include <afxwin.h>
#include "resource.h"//引用是必须的，不然菜单不会出现

class MyFrameWindow:public CFrameWnd
{
public:
    afx_msg void OnPaint()
    {
        CPaintDC paintDC(this);
        paintDC.TextOut(0,0,"这是我的第一个窗口程序");
    }
    afx_msg void OnFileExit()
    {
        PostMessage(WM_CLOSE);
    }
    BOOL PreCreateWindow(CREATESTRUCT& cs)
    {
        cs.hMenu = LoadMenu(NULL,MAKEINTRESOURCE(IDR_MAINMENU));
        return CFrameWnd::PreCreateWindow(cs);
    }
    DECLARE_MESSAGE_MAP()
};

BEGIN_MESSAGE_MAP(MyFrameWindow,CFrameWnd)
    ON_WM_PAINT()
    ON_COMMAND(ID_40003,OnFileExit)
END_MESSAGE_MAP()

class HellowApp:public CWinApp
{
public:
    HellowApp()
        :CWinApp("HelloWorld")
      {}

  BOOL InitInstance()
  {
      HICON hIcon;
      hIcon = LoadIcon(IDIGNORE);
      CFrameWnd *MyFrame = new MyFrameWindow;
      m_pMainWnd = MyFrame;
      MyFrame->Create(NULL,(LPCSTR)"Hellow");
      MyFrame->SetIcon(hIcon,FALSE);//设置窗口的小图标
      MyFrame->SetIcon(hIcon,TRUE);//设置窗口的大图标
      MyFrame->ShowWindow(SW_SHOW);
      return TRUE;
  }

}HellowWorld;

程序运行如图：
