Hey everyone,

I'm trying to send the value from a serial port via myPort.DataReceived() to a textlabel on my windows form. Error is of course, that I can't access the control from a different thread. I know i need to use invoke for that but can't get it right. I tried this:
void startlistening()
   port.DataReceived.BeginInvoke += new SerialDataReceivedEventHandler (port_DataReceived);
void port_DataReceived()
    label.Text = port.ReadExisting();

The easiest way is to set up a method for it:
private void SetLabelText(Label l, string s)
    if (InvokeRequired)
        Invoke(new MethodInvoker(delegate { SetLabelText(l, s); }));
        l.Text = s;
