c# double buffering buttons

Question

I've been working on one project last few months, and have one problem that I can't solve. I have a Windows form with controls on it. When user changes the controls size, app then fires sizechanged event and I move the controls on it accordingly. The main problem is with buttons because they have images - actually to be more precise - they are flat, no border, and have an image on it that's actually a drawn button(reason why I don't draw it by code is because the image is complex). On some machines they start to flicker when app is resizing. Form is set to DoubleBuffered true, and I've used this function to set double buffer on buttons.

public static void SetDoubleBuffered(System.Windows.Forms.Control c)
    {
        if (System.Windows.Forms.SystemInformation.TerminalServerSession)
            return;

        System.Reflection.PropertyInfo aProp =
              typeof(System.Windows.Forms.Control).GetProperty(
                    "DoubleBuffered",
                    System.Reflection.BindingFlags.NonPublic |
                    System.Reflection.BindingFlags.Instance);

        aProp.SetValue(c, true, null);
    }

Any suggestions?

This helped me a lot when I was having problems with double buffering. The code is a bit old, but is still covers the basics.
