vs2010 mfc 没有picturebox怎么办

Question

vs2010 mfc 工具栏中没有picturebox怎么添加，本人编写opencv程序时需要讲图片显示在对话框中，网上很多是用picturebox做的，但我的vs2010没有picturebox

OpenCV中得图可以显示在picture control上，只不过需要把mat对象转成CImage一下，很简单

 void MatToCImage( Mat &mat, CImage &cImage)
{
    //create new CImage
    int width    = mat.cols;
    int height   = mat.rows;
    int channels = mat.channels();

    cImage.Destroy(); //clear
    cImage.Create(width, height,8*channels ); //默认图像像素单通道占用1个字节

    //copy values
    uchar* ps;
    uchar* pimg = (uchar*)cImage.GetBits(); //A pointer to the bitmap buffer
    int step = cImage.GetPitch();

    for (int i = 0; i < height; ++i)
    {
        ps = (mat.ptr<uchar>(i));
        for ( int j = 0; j < width; ++j )
        {
            if ( channels == 1 ) //gray
            {
                *(pimg + i*step + j) = ps[j];
            }
            else if ( channels == 3 ) //color
            {
                for (int k = 0 ; k < 3; ++k )
                {
                    *(pimg + i*step + j*3 + k ) = ps[j*3 + k];
                }           
            }
        }   
    }
}
