This code sample explains how to create a dimmed window covering the whole desktop, and position it behind a VFP top level form -- creating so called "Lightbox effect".

My comment:
The effect is achieved by placing a semi-transparent window below a top-level VFP form. By appying a combination of window styles and extended styles such window is made borderless and inactive.

VFP application can change window`s transparency and color.
