    I overrode WndProc and found that the WM_KEYDOWN message is not being received :-(

    protected override void WndProc(ref System.Windows.Forms.Message m)
    {
    base.WndProc(ref m);
    if(m.Msg == 0x0100)
    Text = "Hello World";
    }

    Nish p.s. In an MC++ program I can #include windows.h to get the defines for various messages, in a C# program how do I get the defines for messages. Above I have hardcoded 0x0100 [WM_KEYDOWN]

      I am deriving a class from ComboBox. I override OnKeyPress. But OnKeyPress never gets called! Anyone knows whether there is anything special I need to be doing? Nish

        Find in Files for WM_KEYDOWN ;P There are a couple programs out there which will let you get the constants but I find it much easier to just do a Find in Files. James Simplicity Rules!

          Incidentally there was a discussion about this in one of my articles Link Don't use WndProc, use PreProcessMessage.

            How your article works. I see that OnKeyPress is getting called. :) Ofcourse highlighting text by mouse doesnot work in your combo box. :(
