CWnd isnt generating mousewheel events

[Carpii]

Hi,
I have a custom CWnd control, using VC6.0
I added a MouseWheel handler to the control

afx_msg BOOL OnMouseWheel(UINT nFlags, short zDelta, CPoint pt);

and a function body,

BOOL CTab::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt)
{
MessageBeep(0);
return 0;
}

When I breakpoint MessageBeep(0), i see that it is not being called
even when I mousewheel over the CWnd control.
Is there anything else I need to do to handle these messages in my
custom control.

Thanks
Carpii

Make sure you have the following added to the BEGIN_MESSAGE_MAP(...) ,
END_MESSAGE_MAP() block.

ON_WM_MOUSEWHEEL()

Make sure the window has the focus, say, by clicking on it.

Be well.

Make sure WS_TABSTOP style is set when creating. Wouldn't work without it
