I run your test.prg. But I don't understand what you don't understand. Probably I'm missing something. I couldn't find the 2 equal handles.

The parent form returns the handle for the its own window. Beeing defined as top level form, it has in fact 2 windows: the form and its client area. The handle is for the form.

The child returns a handle to the window that is the client area of the parent form. Probably you would expect to return a handle to the child form's window (btw, beeing defined as child in top form, it has only one window. Don't ask me why!).

I don't know what's inside your sysinfo class, so, I can't tell you if this is correct or not.

Did I answered your questions?
