I have implemented a property sheet with 8 pages. In each of my propery pages I have lot of controls including edit controls, radio buttons, check boxes etc. I was thinking of a good way to handle these controls. Like, if I use the DDX/DDV for each control its virtually impossible. I heard about using SubclassWindow() for attaining this. But I didn't get it much. I am sure someone out there have done this. It would be appreciated if someone could explain this with a sample code for the same. Waiting for an early response..
