I would like to force the parent window's title bar to paint as Active
when a tool window is active.

Here is my code:

       public const int WM_NCACTIVATE = 0x086;

       protected override void WndProc(ref
System.Windows.Forms.Message m)
       {
           if (m.Msg == WM_NCACTIVATE)
           {
               if (m.WParam == IntPtr.Zero)
               {
                   InteropUtility.SendMessageW(this.Handle,
WM_NCACTIVATE,
                       new IntPtr(1), IntPtr.Zero);

                   return;
               }
           }
           base.WndProc(ref m);
       }

So far, i have only been able to achieve the following results:

a) parent window stays active (though painting in W2K style with no XP
theme) but child window _never becomes active_ and therefore is
unusable

b) child window can be made active but parent window always reverts to
Inactive
