How to enable a child view by mouse click?

[jeffchen]

Hi,

In my program, a MDI program, I have a disabled view. I want to enable it when user clicks the view. I put EnableWindow in CChildFrame::OnMDIActivate(...) . It works. But I always get a 'Ding' noise when click the disabled view. Is there a way to remove the 'Ding' noise or I shall enable the view by other means?

Thanks

Jeff
