vbOnTop - Version 1.0012 The ability to make a form a 'topmost' window, a window that remains visible on top of all other windows even when not activated, is an enhancement frequently requested by VB developers. Core Systems VBOnTop Control provides a means to simply and easily add this capability to your VB forms without code. Just add the control to a form and set its single property, StayOnTop, to true and the form will become a topmost window.
