    I did this :-

    protected override bool IsInputKey(System.Windows.Forms.Keys keyData)
    {
    base.IsInputKey(keyData);
    return true;
    }

    But still OnKeyPress never gets called! Nish

        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. :(
