mfc为对话框添加启动画面

新建CwzdSplash类

CwzdSplash.h

#pragma once  
class CWzdSplash : public CWnd

    // 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(3000);
    wndSplash.DestroyWindow();

添加bmp图片，命名为IDB_SPALSH
