There are a bunch of those application objects that we can instanciate with VFP . Somewhere they may be a master list. I just learned a "new one" last week.

If your question is: How do I know VFP sucessfully instanciated an application object - one trick is with ON ERROR:

cLastOnError=ON('ERROR')
ON ERROR oExcel=NULL
oExcel=CREATOBJECT("Excel.Application")
if oExcel=NULL
   messagebox("Cannot instanciate Excel")
endif
ON ERROR &lcLastOnError
