A simple to use Active X 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.
WM_GETMINMAXINFO is an excellent example of a message
that should have been exposed in the VB form object.
WM_GETMINMAXINFO is a message sent to a window before
its resized. It allows you to set the size
restrictions that should be imposed by the operating
system while the window is being resized. Using the
Form_Resize to restrict the form size does not look as
professional as the resize event does not fire until
the window has been resized. There are thousands of
these messages that allow you to carry out all sorts
of subtle and unsubtle tricks, this control unlocks a
new world of possibilities for the Visual Basic
Developer.
