Noel,

The problem is that VFP has a number of window handles (something like 8 if you start VFP with just the standard tool bar and command window). So finding the right one, if it doesn't have a caption, is, at best, a tricky proposition. I can tell you this, the window will be a child of the VFP desktop window. This is not the value returned by MainhWnd() in Foxtools. The desktop is a child of that window. The earliest that you can retrieve the value is in the .Load event. If you make the window handle a property of the form, you can use _WhTohWnd(_WOntop()) there and pass that value to the function.

Just out of curiousity, may I ask what you're trying to do?

hth,
