------------------------------------------------
Private Sub Form_Load()
Dim inputLine As String
 Dim values As Variant

    Set ServerInfo = New Collection
    If Dir(App.Path & "\Server.txt") <> "" Then
        Open App.Path & "\Server.txt" For Input As #1
        Do While Not EOF(1)
            Line Input #1, inputLine
            values = Split(inputLine, ",")
            Combo1.AddItem values(0)
            ServerInfo.Add inputLine, values(0)
        Loop
        Close #1
    End If

If ServerInfo.Count > 0 Then
        inputString = ServerInfo.Item(Combo1.List(0))
        Combo1.Text = Combo1.List(0)
        values1 = Split(inputString, ",")
        txtServerIP.Text = Trim(values1(1))
        txtPort.Text = Trim(values1(2))
  End If

Private Sub Combo1_Click()

Dim inputString As String
    Dim values As Variant
    If Combo1.ListIndex <> -1 Then
        inputString = ServerInfo.Item(Combo1.List(Combo1.ListIndex))
        values = Split(inputString, ",")
        txtServerIP.Text = Trim(values(1))
        txtPort.Text = Trim(values(2))
       
    End If

End Sub

Just remove the old entry from the collection using the currently selected item in Combo1 as the key.  Then build a new string based the key and the ip/port and add it back to the collection.

Private Sub Command1_Click()
    Dim key As String
    Dim newEntry As String
    Dim values As Variant

    If Combo1.ListIndex <> -1 Then
        key = Combo1.List(Combo1.ListIndex)
        ServerInfo.Remove key
        newEntry = key & ", " Trim(txtServerIP.Text) & ", " & Trim(txtPort.Text)      
        ServerInfo.Add newEntry, key
    End If
End Sub
