client/chat error

VB Code:

Option Explicit
 
Private Sub cmdClose_Click()
    'Disable the outgoing buttons and tell the user
    'that the connection has been closed
    
    wsChat.Close
    cmdClose.Enabled = False
    cmdSend.Enabled = False
    txtName.Enabled = True
    cmdListen.Enabled = True
    cmdConnect.Enabled = True
    txtIn.text = "----- Connection Closed -----" & vbCrLf
End Sub
 
Private Sub cmdConnect_Click()
    'Before we can connect, we should check to see
    'if there is an IP and name for the user.
 
    If txtIP.text = "" Or txtName.text = "" Then
        MsgBox "You must enter both an IP and alias first!", vbCritical, "Error!"
        txtName.SetFocus
        Exit Sub
    End If
    On Error Resume Next
 
    'Connecting the IP that is placed in the txtIP.text value.
 
    wsChat.Close
    wsChat.Connect txtIP.text, 1234
    
    cmdClose.Enabled = True
    cmdListen.Enabled = False
    cmdConnect.Enabled = False
    txtName.Enabled = False
    
End Sub
 
Private Sub cmdListen_Click()
    If txtName.text = "" Then
        MsgBox "You must enter an alias first!", vbCritical, "Error!"
        txtName.SetFocus
        Exit Sub
    End If
 
    'Place the local IP into this textbox and wait for a chat invitation.
 
    txtIP.text = wsChat.LocalIP
    wsChat.Close
    wsChat.LocalPort = 1234
    wsChat.Listen
    cmdClose.Enabled = True
    cmdListen.Enabled = False
    cmdConnect.Enabled = False
    txtName.Enabled = False
    AddText "----- Waiting for Connection -----", txtIn
End Sub
 
Private Sub wsChat_Error(ByVal Number As Integer, Description As String, ByVal Scode As Long, ByVal Source As String, ByVal HelpFile As String, ByVal HelpContext As Long, CancelDisplay As Boolean)
    If Number <> 0 Then
        AddText "----- Error [" & Description & "] -----" & vbCrLf, txtIn
        Call cmdClose_Click
    End If
    
    Do
    DoEvents
    Loop Until wsChat.State = sckConnected Or wsChat.State = sckError
    
    If wsChat.State = sckConnected Then
        'Tell the user that the connection has been established
        AddText "----- Connection Established -----" & vbCrLf, txtIn
        cmdSend.Enabled = True
        txtName.Enabled = False
        txtOut.SetFocus
    Else
        'Tell the user that the connection has been established
        AddText "----- Connection Failed -----" & vbCrLf, txtIn
    End If
End Sub
 
Private Sub AddText(ByVal text As String, ByRef Box As TextBox)
    Box.text = Box.text & text & vbCrLf
    Box.SelStart = Len(Box.text)
 
    'Send the data to the remote user
    wsChat.SendData "[" & txtName.text & "] " & txtOut.text
    AddText "[" & txtName.text & "] " & txtOut.text, txtIn
    
    'Clear out typed text and refocus on the box
    txtOut.text = ""
    txtOut.SetFocus
End Sub

my problem is that when i click on the 'listen' button it gives me a error '40006 saying wrong connection or protocol state' and it highlights this line in the addtext function

wsChat.SendData "[" & txtName.text & "] " & txtOut.text

any ideas why :confused:

i want my computer ip to act as the server, and make clients connect to this server so they can exchange messages
