定位到 void CXXXDlg::OnPaint(),在if()...else()中的else()下添加如下代码:
else { //CDialog::OnPaint();//要禁止这个调用 CPaintDC dc(this); CRect rect; GetClientRect(&rect); CDC dcMem; dcMem.CreateCompatibleDC(&dc); CBitmap bmpBackground; bmpBackground.LoadBitmap(IDB_BITMAP); //IDB_BITMAP:自己导入的位图的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); }
