I was wondering if it is possible to change the border style of a window at run-time.

Ie: I want to change a borderless window to a fixed single border window and vica versa.

VB doesn't seem to allow this...is it possible with API? Or do I have to make a new window everytime?

My reason for asking is that I have a fullscreen OpenGL app that I want to window...but I want it to have a title bar. Many VC++ apps do it, so I hoped there would be a VB way.
