Can't get this code to work when combined

FRUSTRATED!!!! My code is supposed to disconnect the DUN connection at a
specified time (which it does without fail), next my code is supposed to
close a program. Any program will do, we can use "Notepad" for this
example. I've tried three different ways to close Notepad, they all work
when tested, however when I place the code at the end or begining of my
close DUN code it NEVER closes the program! I tried creating a Public
Fnction and a Public Sub that closed the program and was called from the
close DUN code but both produced the same results. Someone has to have
seen this before, I've been chasing this bug for several day now and I'm
burnt out on it!

I've tried the TerminateProcess API function as seen here:
http://www.freevbcode.com/ShowCode.Asp?ID=935

Hopefully someone can help out here. I am lost, I'm not getting any erros,
just not working.

Sorry for the long post

Looks right, you could put your code inside code tags so anyone reading this could easier see your problem, the postmessage call seems to be correct, does this line get fired? put break on that line and check out if you get a handle. If not, put a break before the first if including that line and follow the procedure step by step(F8)

Ok, rather than try & post everything, I created a small project with all the modules, & the form.
It can be downloaded at:
http://www.bigbadbowtie.coloradok5.com/TEMP_CODE.htm

The actual program I am trying to close is AudioGalaxy Satellite Beta. It's available for download at http://www.audiogalaxy.com/betatest2, if anyones so inclined to test it. I'm starting to think it's a problem with their program not mine . Anyway I use WM_QUIT because of a programing glitch in theirs, WM_CLOSE just minimizes their program. IF someone could test it for I'd appreciate it. Like I said the Close Program part of mycode WORKS, but NOT when combbined with the close DUN portion. You could maybe also try another programin place of AudioGalaxy Satellite to prove it's theirs not mine!

TIA
