Try:

DECLARE INTEGER FindWindow IN WIN32API ;
STRING @lpClassName, STRING @TitleStr

This works under all versions of Win95, Win98 and WinNT. The only place that I know of where this statement will not work is on some versions of Win3.x using WIN32s; because WIN32s actually converts the 32-bit API call back to a Win16 call and 'thunks', VFP may not be able to determine the correct provider. I can guarentee you that on a Win32s based system, the provider ISN'T' USER32.DLL.
