Now I feel like an idiot. Since this is my first experience in VB
..NET, I can't even seem to open another form when you click on a
button.

I have a form frmStartup and a button, btnStart. When they tap on the
button, I want the form frmLogin to open using the singleton instance,
but I get nowhere. Can you provide this newbie an example.

Public Class Singleton

' Fields
Private Shared internalInstance As Singleton

' Constructor
Protected Sub New()
End Sub

' Methods
Public Shared Function Instance() As Singleton
' Uses "Lazy initialization"
If (internalInstance Is Nothing) Then
internalInstance = New Singleton
End If
Return internalInstance
End Function

End Class

[Usage]
Dim s1 As Singleton = Singleton.Instance()
