Really, why hide that grey background?

for about 15 years now, Excel, word, ad most of office has had a main
window, and then child windows. It not likely you going to "shock" your
users by eliminating the most common user interface in existence for the
last 15 years.

All this time your wasting could be used to feed the poor, or get your
application done.

I hope, and apologies if I am sounding too harsh, but I just see such a
little benefit for such a huge effort, and so much of the interface breaks.
You REALLY REALLY need to save the "dialog" forms, and the "model" forms for
correctly controlling your users interface. Note that dialog forms, and
model forms HAVE VERY different uses, and which type of form you use will
VERY much be based on the type of flow and UI that you need for your users.
If you hide that window, and set everything to popups, you nearly destroy
the ability fro you to write a correctly functioning application.

You most certainly can, and should hide all of the ms-access interface. The
options to complete hide and keep people out of the ms-access interface can
easily be done using the tools->start-up options. Using those options allows
you to complete hide the ms-access interface (tool bars, database window
etc). Also, using these options means you
do not have to bother setting up security.

Try downloading and running the 3rd example at my following web site that
shows a hidden ms-access interface, and NO CODE is required to do
this....but just some settings in the start-up.

After you try the application, you can exit, and then re-load the
application, but hold down the shift key to by-pass the start-up options. If
want, you can even disable the shift key by pass. I have a sample mdb file
that will let you "set" the shift key bypass on any application you want.

Dale, this is air code, but something along these lines ought to do it:

'----- start of air code -----
Sub SetAllFormsModalPopup(Optional fValue As Boolean = True)

   Dim ao As AccessObject

   DoCmd.Hourglass True

   For Each ao In Application.AllForms

       DoCmd.OpenForm ao.Name, acDesign, _
                   WindowMode:=acHidden

       With Forms(ao.Name)
           .PopUp = bValue
           .Modal = bValue
       End With

       DoCmd.Close acForm, ao.Name, acSaveYes

   Next ao

   DoCmd.Hourglass False
   MsgBox "Done!"

End Sub
'----- end of air code -----

To make all forms PopUp and Modal, execute this:

   SetAllFormsModalPopup

To make all form neither PopUp nor Modal, execute this:

   SetAllFormsModalPopup False
