Public variable As Whatever

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Public Listener As New TcpListener(21)
Listener.Start()

End Sub


it said:
C:\Documents and Settings\JBRANCO\My Documents\Visual Studio Projects\WindowsApplication3\Form1.vb(51): 'Public' is not valid on a local variable declaration.

Dimensioning a public variable has to be done at module level. Like right underneath the line that sets the class name.

Put your declaration of your public variable above your sub/function. Not in Your sub/function. This should work. You do not need another module or class module to declare a public variable.
try omthing like this:

Public Listener As New TcpListener(21)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Listener.Start()

End Sub

hope it helps
