Hi George! I've added the couple methods to my Sysinfo class. These methods retrieve the handle to child window. But the funny thing that happened when I test them: VFP gives the same handle to different instances of child form. As I can conclude from my test (Paul, you're right! <g>), you can't rely on child window handle, VFP handles all on its manner.... I will upload today new version of Sysinfo class with test forms for your testing (may be I'm doing something wrong) >API calls that I hadn't looked at before. > >Finally, you're welcome, but anytime someone has a question regarding the >API, I consider the research a joy, not a chore. So it was my pleasure.
