I need to do the following:
I have a form that has a toolbar associated but I will like to disable a button of the toolbar based on certain conditions, i have the code in the refresh of the form, the problem is that when the form is created the toolbar still does not exists so if i do

oapp.otoolbar.cmdedit.enabled=.f. and error occurs
how can I check that the object exists before attempting this.?

Thanks all
