Disable "X" button on forms in VB6

I tried all the examples on this forum to do this but none seemed to work - the "X" botton still functioned. My big issue is that I create some temp files for WAV and AVI data and want to kill the files when the program closes. With exit buttons or menu selection my code executes fine and all files are eliminated but with the "X" button the clean-up is not done.

Thus I need a very short & consice method of either:

1.) Disabling the "X" button

OR

2.) So mehow executing the cleanup routine when "X" is pressed.

Thanks for any help you can give...again please do not redirect me to existing code links since they did not work...I already tried them.

Add this and it won't matter.

Code:

---

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
  Call MyExit
End Sub

If they click the X, your code will fire.

This will disable the 'x' close button by removing the system menu Close item.
Also removes the menu separator for asthetics.

Always provide a way for the form to be closed.
