just an observation about your question ...
you can make your main form 'modeless' and all your subforms 'modal'.
to access a subform, just issue DO FORM FORM_X. you don't need to set
visible=.F. for your parent form. your don't need to explicitly call
THISFORM.LOSTFOCUS() for your parent form, it gets called automatically.
i suppose if your parent form were larger (dimension) than your subform
and you really didn't want it to show, you could set Visible=.F. , but
you could do that in the LostFocus event for your main form. as for
returning to your parent form from a subform, you just issue THISFORM.RELEASE
and focus will return to your parent form. if you had set visible=.F.
in the parent LostFocus event, you can set Visible=.T. in the parent
GotFocus() event. stylistically, in a subform, i would never refer to
the parent form by name, because i might want to use that subform somewhere
else, and it wouldn't be applicable if the name of the parent form were
different.
only on the 'close' button of the main form, issue a CLEAR EVENTS command
(right after your THISFORM.RELEASE)


as for you other error, i don't see anything wrong with asking 2 questions
at the same time, but i'd address them one at a time. fix your form problem
first, and it may affect your OLE problem.
