Hi,
>Well, so far I am able to get a windowhandle from a childwindow. However, retrieving the title from the window with GetWindowText returns a very constant 0 (zero)
That's correct. The VFP window (_VFP.hwnd) has several child windows that all have no captions. These include the toolbar area, the status bar and the _SCREEN window. The _SCREEN window has also child windows which are the ones you are looking for. What you need to do is to drill down from the child windows, as well.
If you have Visual Studio, you can use Spy++ to check out the window structure of VFP.
