PowerBuilder and Colors

Well, if you sit in front of your computer as often as I do, you might not. However, the following problem may have occurred: you want to create a cool window in which the data and the headers are displayed in different colors, but you can't find the right one. If you've come across this situation before, then this article is right for you. What Is Light? Let's discuss a bit of physics. If you look at a cool DVD movie, you hear sound and see pictures...
