It is visible and I can see a title bar, but it doesn't get recognized by the GetWindow loop. What else could I do to find it? I need to wait until it is done with what it is doing before I can continue in my program.

DECLARE INTEGER GetDesktopWindow IN Win32API

>>>lnhwnd = GetDesktopWindow()
>>>lnchild = GetWindow(lnhwnd, GW_CHILD) && GW_CHILD = 5

The proceed from there using GW_HWNDNEXT.

>One problem here - GetWindow(), when applied to situations starting from the Desktop Window, will only show Top-Level Windows, and not the children of those Windows. Unfortunately, the best solution, EnumWindows() i not trivially implemented in VFP - it requires a callback, and as a result needs an OCX or DLL to provide the enumerator callback. There are several examples of FLLs used for such purposes in the Files section.

Ed,

Here I assumed that the top-level windows were the only one's needed because of the nature of the question. If, however, all windows are desired, as you know, GetWindow() can still be used by enumerating from each top-level using GW_CHILD. This is the technique I use with SpyFoxFox in the download section.

I agree, BTW, that EnumWindows() would be the best choice if it were more easily implemented from within VFP.
