vs2010线程求助

本人想在vs2010上编写基于对话框的视频播放器，需要用到线程，问题是所创建的线程无法调用线程函数，而在vs2008上运行则能调用线程函数，请各位大侠指点，代码如下：
UINT  processImages(LPVOID pParam )
{
        /*CITS_Vehicle_DetectionDlg *ITSdlg = reinterpret_cast<CITS_Vehicle_DetectionDlg*>(g);*/
        CITS_Vehicle_DetectionDlg *ITSdlg =(CITS_Vehicle_DetectionDlg*) pParam;
        while(!ITSdlg->IsStop())
        {
                if(cvGrabFrame(ITSdlg->capture))
                {
                        ITSdlg->Img = cvRetrieveFrame(ITSdlg->capture);
                        ITSdlg->DrawPicToHDC(ITSdlg->Img);
                        cvWaitKey(20);

                }
        }
        return 0;



CITS_Vehicle_DetectionDlg* dlg = new CITS_Vehicle_DetectionDlg;
        AfxBeginThread(processImages,dlg);
