How do I stop a program from running twice?

[Adric]

I am writing an auto run program for a cd I am making. When I put the cd in the drive, the program loads twice. Is there any code I can use to stop the program from loading if it is already running?

Hi,

The App.PrevInstance returns a value to indicate if the program is already running.

So i would write
if app.PrevInstance=True then
unload me
end if

Sorry I should have made that a bit clearer.

If you check out the following article in MSDN, it gives more comprehensive details:

I don't have msdn. I was given the disc by my professor at a college one year ago and it was not included.
