将OpenCV捕获的摄像头加载到picture控件中

CRect rect;

 CDC* pDC;
 HDC hDC;

 pStc = (CStatic*)GetDlgItem(IDC_CAM);//IDC_CAM是Picture控件的ID

//拿到控件的大小
 pStc->GetClientRect(&rect);

//获取控件的句柄
 pDC = pStc->GetDC();
 hDC = pDC->GetSafeHdc();
 //声明IplImage指针
 IplImage* pFrame = NULL;
 //获取摄像头
 CvCapture* pCapture = cvCreateCameraCapture(-1);

 while(1)
 {
  pFrame = cvQueryFrame(pCapture);
  if(!pFrame)break;

//CvvImage.h和CvvImage.cpp在OPENCV2.2之后的版本就没了,自己去下载个就行了
  CvvImage m_Cvv;
  m_Cvv.CopyOf(pFrame,pFrame->nChannels);
  m_Cvv.DrawToHDC(hDC,&rect);

//等待30秒或按ESC键退出
  char c = cvWaitKey(30);
  if(c==27)break;
 }

//释放
 cvReleaseCapture(&pCapture);
