Threading error with 2005 com port

[Gary Kahrau]

I hope this is a simple question for threading people. VB 2005 Beta2
has a new SerialPort control.

I can read the data that I want just fine. However when I try to
display the text, I get a threading error. See event code and error
message below.
How do I get around this threading error???

Private Sub SerialPort1_DataReceived1(ByVal sender As Object,
ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles
SerialPort1.DataReceived
txt = SerialPort1.ReadLine
lbData.text = txt ' <--- Get thread error here.
End Sub
Error message ------------------------
Cross-thread operation not valid: Control 'lbData' accessed from a
thread other than the thread it was created on.
---------------------------------------------

Thanks,
Gary...

[stand__sure]

you'll need to marshall the call using the begin invoke. I show to how to
do this here: http://code.box.sk/newsread.php?newsid=717
