Is there a better code to use to ensure that every frm in my program is unloaded?

I have seen a code that I can place in a Module and call that Public sub from within every form's Unload. Does it work and what is that code?

I have a rather large program that when it is closed VB still shows that it is running. From what I can see, every form has a:

"Unload me"
"frmBlahBlah.Show"
Etc...Ect...

What is my problem do you think?
Any ideas or suggestion are greatly welcomed,
