That's possible Ray. The not-so-obvious bit is how to share the
loaded data later. As I said, the threads are independent in almost
every way, and share no data by default. If you were to pass the
resulting Recordset via a COM call between threads (or processes)
then it could also take a long time. Do you know why the database loading is so slow? How much data are
you talking about?

It's not that much data, it's just coming over a slow WAN link, which

I'm just looking for an example or two of how to do a "background"
process in VB so the user could start to log in to the app while the
data continues to load.

Instead of making them start at a splash screen or hourglass for a
minute, I'd like the data to load in the background while they log in.

This is quite possible with an activeX exe (out-of-process) server that
loads the data, and raises an event when done.

Instance it "withevents", and your app will be notified when data is
available.

(If I remember correctly, the "CoffeeTimer" example in the VB manual
show an example of this).

If you can't grok it, post a note here, and I'll whip something together
for you... (but give it a try first... (deadlines haunt me these days)).

The best I could think of would be to use a timer and a status flag to
make sure the data load only runs once, but then I still have a timer
running every x seconds doing nothing other than going "yup, already
ran..."

That is easily fixed by setting Timer1.Enabled = False once you're done.


much thanks for the pointers... I learn something new every day. :)
