Something like:
llempty=.f.
for ia=1 to thisform.controlCount
if thisform.Controls(ia).BaseClass="Textbox" and empty(thisform.Controls(ia).Value)
llempty=.t.
EXIT
endif
endfor
if llempty
thisform.Controls(ia).setfocus
endif

>Is there a way I can have my app check to determine if any fields are left empty on a form. If it finds a field that is empty, the user shoudl be prompted and the textbox that the has that field as a control source should be setfocused. Any ideas?
