if there is code to do it in petzold then just "learn" from it and rewrite it
yourself. if every windows program that was written from knowledge gleaned from
perzold had to follow that license (just read it) they would all have to give
credit to petzold! seriously... just look at it to learn the APIs. then write it
yourself, you should be in the clear! i won't tell <grin>
