2.连接视频设备
capDriverConnect(this->m_hWndCapture,nDevice);
3.拷贝到剪贴板：
if(!capEditCopy(this->m_hWndCapture)) return ;
::OpenClipboard(this->m_hWndCapture);
HBITMAP hBitmap = (HBITMAP)::GetClipboardData(CF_BITMAP);
::CloseClipboard();
        /*SaveBmpToFile --〉将剪贴板内容保存为文件*/
BOOL bRet = SaveBmpToFile(hBitmap,strPathName);
