Jon,

Here's the declaration:

DECLARE INTEGER GetTopWindow IN WIN32API;
INTEGER hwnd

Then to retrieve the child window:

lnmainhwnd = MainHWnd()
lnchildhwnd = GetTopWindow(lnmainhwnd)

However, I personally think that it's easier to use the FoxHWnd control and pass the HWnd property of that to whatever is going to use it. I done some work with it and it seems to work as advertised.
