Hi,

VARTYPE() works fine in those cases where the object reference has been set to NULL. It doesn't work well when the object is released, but the reference not updated. This happens mostly with COM objects:

ox = CreateObject("Word.Application")
ox.Quit()
? Vartype(ox)   && prints 'O'

With COM objects I'd use TYPE(), except when my intention is to check whether I assigned an object reference at all. Another scenario where I frequently use TYPE() instead of VARTYPE() is accessing the ActiveForm and ActiveControls properties.
