Image of control

Question

Is there any way to save an image of a control?

I have a graph that I am using from a package, but I made a custom control that would hover with your mouse and tell you the Y values according to the mouse's position relative to X on this pre-made graph control. If you click on the control, it will "paste" my control onto the graph. The graph can be exported as a .bmp, but since my control is not part of the graph, it does not get exported.


Thanks.

Hi,

You can use the following method.

        public Image GetImageOfControl(Control c)
        {
            Rectangle rc = new Rectangle(this.PointToScreen(c.Location), c.Size);
            Image i = new Bitmap(rc.Width, rc.Height);
            Graphics g = Graphics.FromImage(i);
            g.CopyFromScreen(rc.Left, rc.Top, 0, 0, rc.Size);
            g.Dispose();
            return i;
        }

That did the trick! Just needed the tiniest bit of retooling for C++.


Thanks!
