upgrade from vb6 issue...

hi, i found a class module from planetsourcecode in vb6 used to log browser activity.. i wanted to convert it into .net.. but the issue is it uses linkmode constants.. and as far as ive read they aren't supported in .net. so what should i use in this piece of code?? plz help..

Code:

---

Option Explicit

Private txtMon As Object
Public LastURL As String
Public WithEvents myTimer As Timer
Public Active As Boolean

Public Event TitleChanged(Title As String)
Public Event URLChanged(URL As String)

Private WithEvents MTimer As Timer

Private Sub LinkTextBox(ByRef pTextBox As TextBox, plinkTopic As String, plinkMode As LinkModeConstants, plinkItem As Variant)
On Local Error GoTo listen:
  pTextBox.LinkTopic = plinkTopic
  pTextBox.LinkTimeout = 10
  pTextBox.LinkMode = plinkMode
  pTextBox.LinkItem = plinkItem
  pTextBox.LinkRequest
listen:
  On Error GoTo 0
End Sub

Public Sub GetDDEURL(LinkTopic As String)
Dim sTmp As String, sLink() As String
    Call LinkTextBox(txtMon, LinkTopic, vbLinkManual, &HFFFFFFFF)
    sTmp = Mid(txtMon.Text, 2)
    sLink = VBA.Split(sTmp, """,""")
    If UBound(sLink) > 0 Then
        If VBA.Left(sLink(0), 1) = """" Then
            sTmp = Mid(sLink(0), 2, Len(sLink(0)) - 1)
        Else
            sTmp = sLink(0)
        End If
       
        If sTmp <> LastURL Then
            RaiseEvent URLChanged(sTmp)
            LastURL = sTmp
           
            If sLink(1) <> "" Then
                If VBA.Right(sLink(1), 1) = """" Then
                    sTmp = VBA.Left(sLink(1), Len(sLink(1)) - 1)
                Else
                    sTmp = sLink(1)
                End If
                   
                RaiseEvent TitleChanged(sTmp)
            End If
        End If
    End If
End Sub

Public Sub StartMon(TextBoxCtl As Object, myTimer As Object)
    Set txtMon = TextBoxCtl
    myTimer.Interval = 500
myTimer.Enabled = True
End Sub

Public Sub StopMon()
    myTimer.Enabled = False
    End Sub
