Hi,

Thanks to a certain someone named "Gary"

http://www.codenewsgroups.net/group/microsoft.public.vb.general.discussion/topic16868.aspx

when doing a Google search (Google, if you are reading this message, bring
back the old Google News!) solved the problem. I tried Gary's suggestion in
my Project1 and it worked. Here is what Gary said on the topic:

-------------------------------------------------------------------------------------
Paul,

I finally discovered the problem. An OCX had a form that didn't have Unload
Me in the QueryUnload event. Apparently every QueryUnload in every form of
both the EXE and any OCXs or DLLs called by the EXE must have:

If UnloadMode =2 then Unload Me

Gary
-------------------------------------------------------------------------------------

I did a Google search on UnloadMode constants, since I agree that "2" is
annoying to look at and came up with:

QueryUnload:
vbFormControlMenu = 0
vbFormCode = 1
vbAppWindows = 2
vbAppTaskManager = 3
vbFormMDIForm = 4
vbFormOwner = 5

That makes Gary's added line:

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
If UnloadMode = vbAppWindows Then
Unload Me
End If
End Sub

There is no subclassing necessary, but every form and every OCX apparently
must process this request.

Thanks,

Sarah

(You used to be able to put multiple newsgroup names to include
comp.???.* as well in there but Google dropped that capability years
ago.)

Pardon me for saying this, but that just sounds incredibly
superstitious.

Yes, if Windows is shutting down, logo requirements aside, it makes
sense you'd want your application to end gracefully.

That means what it means, and is entirely independent of your
application architecture.

Implication? The code above may indeed help you pass some test or
another, but it doesn't address the goal.

Programming is *not* a mindless pursuit...
