MethodInvoker and passing Arguments

Probably another easy question, but I'm stumped.

So, if InvokeRequired is true then it invokes.  But the function has arguments.

Either way, if I pass them after AddressOf, the compiler complains.

If i dont pass them, vb.net has a problem, says I need to pass them.


Public Sub addscandata(ByVal target As String, ByVal port As Integer, ByVal stat As String)

        If Me.InvokeRequired Then
            Me.Invoke(New MethodInvoker(AddressOf addscandata()))
        Else

            rtb_scan_data.AppendText(stat & ":" & target & ":" & port)

        End If
    End Sub

Create a delegate with the same signature as your method and then use it along with an array of object to pass the parameters:
Public Delegate Sub ScanDataDelegate(ByVal target As String, ByVal port As Integer, ByVal stat As String)

    Public Sub addscandata(ByVal target As String, ByVal port As Integer, ByVal stat As String)
        If Me.InvokeRequired Then
            Me.Invoke(New ScanDataDelegate(AddressOf addscandata), New Object() {target, port, stat})
        Else
            rtb_scan_data.AppendText(stat & ":" & target & ":" & port)
        End If
    End Sub
