很简单的问题 VC++中怎样设置窗口背景

Answer 1

首先载入BITMAP到资源视图中，然后再OnPaint()函数中else语句中，注释掉CDialogEx::OnPaint();再加上
CPaintDC dc(this);

CDC memdc;
memdc.CreateCompatibleDC(&dc); //创建兼容DC

CBitmap bkg;
bkg.LoadBitmap(IDB_BITMAP1); //载入位图，就是之前载入的位图

BITMAP bkginfo;
bkg.GetBitmap(&bkginfo); //获取位图信息

memdc.SelectObject(&bkg);

RECT rect;
GetWindowRect(&rect); //获取对话框信息

dc.StretchBlt(0,0,rect.right-rect.left,rect.bottom-rect.top,&memdc,0,0,
bkginfo.bmWidth,bkginfo.bmHeight,SRCCOPY);
