1.在资源里导入一个bmp图片假设名称为IDB_BITMAP1

实现OnPaint方法

CPaintDC dc(this);     CRect   rect;       GetClientRect(&rect);       CDC   dcMem;       dcMem.CreateCompatibleDC(&dc);       CBitmap   bmpBackground;       bmpBackground.LoadBitmap(IDB_BITMAP1);               //IDB_BITMAP是你自己的图对应的ID       BITMAP   bitmap;       bmpBackground.GetBitmap(&bitmap);       CBitmap   *pbmpOld=dcMem.SelectObject(&bmpBackground);       dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,       bitmap.bmWidth,bitmap.bmHeight,SRCCOPY);
