No it's not. The batch file can launch an EXE that is written in VFP that instantiates the object and calls the method. So you'd have something like a 2 line program:
ox = newobject(...)
ox.DoIt()
>Is it possible to do a call to a custom class method from a batch file? I would like to use a windows schedule timer to post data to a public file for all network users.
