>>>Hi!
>>>I am using a loop with GetWindow and GW_HWNDNEXT, but the window I am looking for does not come up in the list. 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.
