I have a logon screen thats not part of my MDI. With a successful login the user then gets taken to the MDI. The problem is with this code:

Code:
frmCalling1 = New frmCalling()
        frmCalling1.Show()
        Me.Close()
when the logon screen closes the entire application ends. If I take out the me.close, it goes to the MDI, but the login screen stays open in the background...any suggestions how to close the login screen without closing the entire app?
