Annoying beep sound in MFC dialog

[Garstyciuks]

I have a custom control in my dialog. It should be focusable and handle keyboard messages. When I press buttons, handles keyboard messages fine, but it always plays "beep" windows sound. I don't know how to fix it. And I think that it isn't "focusable". If you know any good articles about input and MFC, please tell me.

I would say you should forward any messages it wants to it. Some controls cannot take focus I suppose.

It is a control which I have created. I don't know how to make it "focusable"

Yes, well, I'm not experienced in developing my own ActiveX controls, as I have never done so in c++, so in that regard I cannot help you.
