mfc为对话框添加启动画面

新建CwzdSplash类

CwzdSplash.h

 #pragma once
 class CWzdSplash : public CWnd
 {
     DECLARE_DYNAMIC(CWzdSplash)
 public:
     CWzdSplash();
     virtual ~CWzdSplash();
 protected:
     DECLARE_MESSAGE_MAP()
 public:
     CBitmap m_bitmap;
 //  void Create(void);
     void Create(UINT nBitmapID);
     afx_msg void OnPaint();
     afx_msg void OnTimer(UINT_PTR nIDEvent);  

 };

 void CWzdSplash::OnPaint()

     // TODO: 在此处添加消息处理程序代码
     // 不为绘图消息调用 CWnd::OnPaint()
     CPaintDC dc(this); // device context forpainting
     BITMAP bitmap;
     m_bitmap.GetBitmap(&bitmap);
     CDC dcComp;
     dcComp.CreateCompatibleDC(&dc);

 {
     // TODO: 在此添加消息处理程序代码和/或调用默认值
     //CWnd::OnTimer(nIDEvent);
     DestroyWindow(); //销毁初始画面窗口
 }  

在主窗口初始化处添加代码

 //添加启动画面
     CWzdSplash wndSplash;
     wndSplash.Create(IDB_SPLASH);
     wndSplash.CenterWindow();
     wndSplash.UpdateWindow();
     Sleep();
     wndSplash.DestroyWindow();

添加bmp图片，命名为IDB_SPALSH
