problem with thread safe changing controls-agian

[dreamdelerium]

now that ive changed my code around i can no longer change a control on my main form from a class thats being run on a different thread.
my onload event has this:

WC = New Class2
        ThreadingPool.QueueUserWorkItem(AddressOf WC.FindMyPort)

which runs the wc.findmyport sub in the class2 class. i tried using this:

Private Delegate Function GetControlTextInvoker(ByVal ctl As Control) As String Private Function GetControlText(ByVal ctl As Control) As String   
 Dim text As String     
If ctl.InvokeRequired Then        
text = CStr(ctl.Invoke(New GetControlTextInvoker(AddressOf GetControlText), ctl))    
Else        
text = ctl.Text   
 End If    
 Return textEnd Function

but its not longer working. i assume because im working with two different classes. ive tried changing everything from private to public. what i want to do is change a label's text on my main form from my class2 class being run on a seperate thread
