how to exit threads in VB5

hi,
i'm using Threads in VB5.
i'm trying to use a simple thread in a form.
i can create one,then suspend it ,setting it's priority to min and resume the same thread.
when i'm trying to kill it i use GetExitCode and then terminateThread .
when i run it it's ok but i can't close the program (the project
still runs in the background)

help

I had problems with a persistent app that wouldn't close. Check out Aaron's response, which worked for me.
