MFC联合HAlcon双相机单帧采集图片
这里写自定义目录标题
问题：程序运行时首次采集都能行，再次点击CCD1，CCD2采集按钮，MFC界面的Picture Contrl控件直接黑屏了，但是我在if(CCD1==0){ }内增加了状态显示程序，显示已经进入到了if(){}语句内，但是图像就是显示不了，不清楚为什么？有木有大神知道原因
//CCD1采集按钮的程序
void CCounterPointsDlg::OnBnClickedCcd1PictureGet()
{
// TODO: 在此添加控件通知处理程序代码
//CCD1相机打开
OpenFramegrabber("DahengCAM", 1, 1, 0, 0, 0, 0, "interlaced", 8, "gray", -1, "false",

附上我用MFC做的UI界面，刚学MFC没多久，让各位大神见笑了
