用一个位图平铺到客户端

代码很简单，不作说明

void CStretchDlg::OnPaint()

{

     CPaintDC dc(this);

     CDC dcMem;

     dcMem.CreateCompatibleDC(&dc);

     CBitmap bitmap;

     bitmap.LoadBitmap(IDB_BITMAP1);

     BITMAP bmpInfo;

     CSize siBitmap;

     if( GetObject(bitmap, sizeof(bmpInfo), &bmpInfo ) )

     {

         siBitmap.cx = bmpInfo.bmWidth;

         siBitmap.cy = bmpInfo.bmHeight;

     }

    

     dcMem.SelectObject(&bitmap);

    

     CRect rtClient;

     GetClientRect(rtClient);

     for( int x=0; x<rtClient.Width(); x += siBitmap.cx )

     {

         for( int y=0; y<rtClient.Height(); y += siBitmap.cy )

         {

              dc.BitBlt( x, y, siBitmap.cx, siBitmap.cy, &dcMem, 0, 0, SRCCOPY );

         }

     }

 

     CDialog::OnPaint();

}
