Toggle a Form's Caption Bar at Runtime
This code allows a user to Toggle the caption bar (toolbox and all) on a form at runtime. Normally you cannot visually change some of the form's settings at runtime this solves one of those instances.
Code can be fairly easily changed so as to accept a parameter for if you want the caption or not. This is just a simple example.
Assumes
This simply changes the window style of the form and then does a couple of extremely quick re-sizes so that the caption area is forced to redraw. This will only work as is if the code is placed in the form you want to affect.
Sub must be called for changes to take effect.
