Hi GMorgan, how abt this:

   Case Else
       mnu_options.Visible = False
   End Select
End Sub


'let there be menu in the form, say "mnu_options" which you can show at the right click on the icon.
The menu will have an "exit" also , which when clicked will unload/end the appliction.

'---------------------------
Create an exe of this project. When you run the exe, it sits at the system tray of your pc. Put this
exe in your startup folder of your machine, so will be loaded automatically when the pc is booted!

And for minimizing the borderless window, I think basically you have to change the window state of the form. You can do so at the double click of the form of at a command button of the form or anywhere where you think it is apt.

I have tried in the command button of a 'Borderless form'(borderless means the form's BorderStyle="none'")

Private Sub Command1_Click()
Form2.WindowState = vbMinimized
End Sub

I hope this is what you wanted and it helps!
