[RESOLVED] Using SendOrPostCallback

[KKW]

Hello,
I'm hoping someone can help me with this. I'm new to C#, and can't figure out how to correct this.
I get the error: No overload for 'Lbl39Text' matches delegate 'System.Threading.SendOrPostCallback'

I'm using VS2010.

See the attached offending code (in red)!

Thanks!

private void Lbl39Text(string NewText)
        {
            this.Label39.Text = NewText;
            this.Refresh();
        }

if (this.Label39.InvokeRequired) {
      // It's on a different thread, so use Invoke.

      SendOrPostCallback d1 = new SendOrPostCallback(Lbl39Text);      
      this.Invoke(d1, new object[] { NewText });
} else {
     // It's on the same thread, no need for Invoke.
     this.Label39.Text = NewText;
     Refresh();
}
