Hi,

I am following up on an older thread about resizing a panel in a form
with the mouse.

http://groups.google.de/group/microsoft.public.dotnet.framework.windowsforms/bro
wse_thread/thread/25b6d27b21064907/bb247a9b14219d94?lnk=st&q=pop+up+user+control
+resizable&rnum=1&hl=de#bb247a9b14219d94

I tried this code to manipulate the right border of the panel but I
have a problem:

public class SizablePanel : Panel
{
   private const int WM_NCHITTEST = 0x0084;
   private const int HTRIGHT = 11;

   protected override void WndProc(ref Message m)
   {
       base.WndProc(ref m);
       if (m.Msg == WM_NCHITTEST)
       {
           Point pos = new Point((int)m.LParam);
           pos = this.PointToClient(pos);
           if (pos.X > this.Width - 5)
               m.Result = new IntPtr(HTRIGHT);
       }
   }
}

I cannot make the panel narrower than about 120 pixel.
Does anyone have a solution to that?

Also I would like to drag the panel horizontally.
