在很多系统中出于美观的需要常常要设置背景图片。下面我介绍一种在客户区设置背景图片的简单方法。

1 ．将背景 bmp 图片导入到工程，资源 ID 这里假设为 IDB_BITMAP1

2 ．在视图类添加如下代码：

void CSetBkMapView::OnDraw(CDC* pDC) { CSetBkMapDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); if (!pDoc) return; // TODO: 在此处为本机数据添加绘制代码 // 获取客户区大小 CRect rcClient; GetClientRect(&rcClient); CBitmap bmp; // 定义一个位图变量 CBitmap* oldBmp; CDC memDC; bmp.LoadBitmap(IDB_BITMAP1); // 获取位图信息 BITMAP bm; bmp.GetBitmap( &bm ); memDC.CreateCompatibleDC(pDC); oldBmp=memDC.SelectObject(&bmp); // 将位图资源选入内存DC // 在客户区绘制位图 pDC->BitBlt(0,0,bm.bmWidth,bm.bmHeight,&memDC,0,0,SRCCOPY); memDC.SelectObject(oldBmp);// 将旧位图选回设备环境 bmp.DeleteObject(); // 删除位图资源 memDC.DeleteDC(); // 删除内存DC }

效果图如下：
