Neil (and Miguel too),

After looking at the code in the KB article, I saw an reference to a property that's undocumented in the treeview (and I'd guess that it's also available in the listview). I did a little testing, and determined that it does indeed exist. The property is the window handle of the treeview, named hWnd.

The only question that remains (and hopefully Miguel can answer this one for us) is will this work? VFP doesn't handle windows messagaging the same way that other applications do, so there's a chance that it may not let this happen. At any rate, if Miguel will report back to us, we'll know the answer.
