首先的窗口输出一些内容;
菜单单击函数代码;
void CgetmypicView::OnTestGetmypic()
{// TODO: 在此添加命令处理程序代码HWND hwnd = this->GetSafeHwnd();HDC hDC = ::GetWindowDC(hwnd);//获取DC RECT rect;::GetClientRect(hwnd, &rect);//获取客户区大小 HDC hDCMem = ::CreateCompatibleDC(hDC);//创建兼容DC HBITMAP hBitMap = ::CreateCompatibleBitmap(hDC, rect.right, rect.bottom);//创建兼容位图 HBITMAP hOldMap = (HBITMAP)::SelectObject(hDCMem, hBitMap);//将位图选入DC。并保存返回值 ::BitBlt(hDCMem, 0, 0, rect.right, rect.bottom, hDC, 0, 0, SRCCOPY);//将图象拷贝到内存DC中 CImage image;image.Attach(hBitMap);image.Save(_T("e://myshige.jpg"));//假设文件后缀为.bmp,则保存为为bmp格式 image.Detach();::SelectObject(hDCMem, hOldMap);//选入上次的返回值 //释放 ::DeleteObject(hBitMap);::DeleteDC(hDCMem);::DeleteDC(hDC);
}
单击菜单之后在磁盘生成图片文件,打开如下;
