Selecting Colors from Anywhere on the Screen

I have been at this for a long time now. Back in school I learned FORTRAN. Around 1970 I was hired by Burroughs Corp (ALGOL, ESPOL.) After that I worked at the University of Delaware (APL, Pascal) and at Clarion University of Pennsylvania (TRS-80 and Apple BASIC.) In 1986 I started Hufnagel Software and today publish a CAD package for event design called PartyCAD (VB6.) My latest enthusiasm though is learning C#.
