Using VB6 and winsock to connect to a router and issue a command, currently I can -

1) Connect to a router
2) Issue a command
3) Disconnect

But what I would like to do it -

1) Connect to a router
2) Issue a command
3) Output the routers response to textfile1
4) Issue another command
5) Output the routers response to textfile2
6) Disconnect

Any ideas???????????

Try this code (not tested), but logic should work:


Private bSecond As Boolean

Private Sub Command1_Click()
    bSecond = False
    Winsock1.Close
    Winsock1.Connect "10.10.0.60", 23
End Sub

Private Sub Winsock1_Connect()
    If bSecond = False Then
        Winsock1.SendData "strdata1"
    End If
End Sub

Private Sub Winsock1_DataArrival(ByVal bytesTotal As Long)
    Dim strData As String, strFile As String
    strData = String(bytesTotal, Chr$(0))
    Winsock1.GetData strData, vbString, bytesTotal
    If bSecond = False Then
        strFile = "c:\test1.txt"
    Else
        strFile = "c:\test2.txt"
    End If
    WriteToFile strFile, strData
End Sub

Private Sub WriteToFile(strFile As String, strData As String)
    Dim oFSO As New Scripting.FileSystemObject
    Dim oStream As TextStream
    Set oStream = oFSO.OpenTextFile(strFile, ForWriting)
    oStream.Write strData
    oStream.Close
    If bSecond = False Then
        Winsock1.SendData "strdata2"
        bSecond = True
    Else
        Winsock1.Close
    End If
    Set oFSO = Nothing
End Sub

Private Sub Winsock1_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)
    MsgBox "Error occurred: " & Description
End Sub

Try this:

Private Sub WriteToFile(strFile As String, strData As String)
    Dim oFSO As Object
    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Dim oStream As Object
    Set oStream = oFSO.OpenTextFile(strFile, 2)
    oStream.Write strData
    oStream.Close
    If bSecond = False Then
        Winsock1.SendData "strdata2"
        bSecond = True
    Else
        Winsock1.Close
    End If
    Set oFSO = Nothing
End Sub
