Form show question

[Peter]

I want to have a form named 'frmUpdating' that pops up on a clients
screen while a loop is cycling and disapears when the loop ends.

The 'frmUpdating' form has a real cool animation on it and it starts
running immediately after it is shown. It loops indefinately.

What I want to be able to do is have this form show up on the first
cycle of the loop and then exit after the loop exits.

How should I tackle this problem?

before the 'for' statement - show the form
and
after the 'next' statement - unload the form

Peter... Might not be as simple as just show and hide... Please check into
threading, to show animation on the popup form.

see this topic of disscussion...

When I use this code I recieve the following error:
It is invalid to start a second message loop on a single thread. Use
Application.RunDialog or Form.ShowDialog instead.

Is there a way around this?

Alright, I have read the info on thread pool and want to see if I got this right.

I could create a Proceedure Named RunGif().
In this proceedure setup my looping animation.

So from my main thread Public Sub Main()
I would call on this proceedure RunGif() like this..."

threadpool.queUserWorkitem(new waitcallback(addressof RubnGif)

Is it possible then to kill this thread manually?

Are you attempting to call 'Application.Run(...)' more than once? Like
the message above says, you can only call this method once. After doing
that, you can instantiate forms and call their 'Show' or 'ShowDialog'
methods.
