A simple to use ActiveX Subclassing control for Visual Basic that is debug safe in the Visual Basic IDE. Subclassing is a powerful technique that allows you to modify the normal behaviour of the controls and forms in your application. Visual Basic makes some, but not all, of the message available through class methods and the event system. The trouble is that many of these hidden messages are actually very useful.
The control element accomplishes a subclassing for a window stated by its handle. The window function is the function of a window, which completely determines the behavior of the window (and thus the reaction of the window to user inputs). This window function is replaced by another function by the Subclassing component. This function then can be freely defined in the Message event of the Subclassing control element (MS Windows API programming).
