Program takes 30 seconds to shutdown

I have a VB5 program that closes its main form, then hits the END, but
if you look at processes running with CTRL-ALT-DELETE, it is still there
for between 20-30 seconds. Any ideas?

Do you have a timer control there, or other a TreeView, or other controls?
Timers should be disabled before termination of a program, and all objects
should be released (set to Nothing).

I have this same problem, it started happening to me when I upgraded the
Internet Transfer Control to SP2. If I go back to the original, the
problem goes away, but then the control doesn't work anymore.

I think I've turned off all of the timers. What kind of objects need to be set
to nothing? I have lots of controls, on different forms. Does every control on
any form need to be set to nothing?

Controls should be unloaded with the form, so no special precautions are
necessary besides with Timer controls, and perhaps Data controls, where you
can close the database before Unload. Perhaps also OLE containers can be
emptied. But you cannot set a control to Nothing, I think, and it's never
required.

You nailed that one. The Internet Transfer Control hangs until it's timeout
is reached. So, when my program starts to shutdown, I'm setting
RequestTimeout for all Inet controls to 1. It still takes 1 second, but
that is way better than 30.

Also when you create a form, let's say, and want to destroy that
object.. It would be something like:

Dim oNewForm as New frmMain

oNewForm.Text1.Text = "Sending without seeing the form load.."
oNewForm.Show 1
MsgBox oNewForm.Text1.Text
oNewForm = Nothing
