Hello folks,
Probably an idiotic question - I'm trying to do some work in my newly acquired VFP9, having done very little other than FPW26 programming this year - my feeble VFP skills are very rusty...
I have a form called hugform (the name is "hugform" and the scx is "hugform.scx"), which can behave in various ways depending on the setting of a global variable. How can I tell whether an instance of this form is already open when a menu item is selected, so that I can ensure the existing instance is released?
This doesn't work:
IF VARTYPE(HUGForm) <> "O"
RELEASE hugform
DO FORM hugform.scx
ELSE
DO FORM hugform.scx
endif
vartype(hugform) never seems to be able to "see" hugform.
Any help gratedully received!
