Hallo Christoph, wie kann ich die zwei Methoden zu einem in AddToLog implementieren?

Public Sub AddToLog(ByVal logString As String, ByVal boolConnected As Boolean, _
  ByVal e As DeviceEventArgs)
 
If TextBox1.InvokeRequired = True Then
 
  If boolConnected = True Then
   ' Call this method again but on the GUI thread
    TextBox1.Invoke(New VisualizeDeviceEventHandler(AddressOf _
    UpdateConsoleDeviceConnected), New Object() {e})
  Else
    ' Call this method again but on the GUI thread
     TextBox1.Invoke(New VisualizeDeviceEventHandler(AddressOf _
     UpdateConsoleDeviceDisConnected), New Object() {e})
  End If
 
Else
 TextBox1.AppendText(logString + Environment.NewLine)
End If
 
End Sub
