am i missing something here. i get error
'Txt' is a 'variable' but is used like a 'method' E:\TradingTools\CODE
\collectTickData\Form1.cs
i dont see anything wrong.
private delegate void appendToTextBoxDelegate(String Txt);
private void appendToTextBox(String Txt)
{
if (this.InvokeRequired)
{
this.BeginInvoke(new appendToTextBoxDelegate(Txt), new
object[] { Txt }); // <<<<<<<<<THIS IS WHERE IT ERRORS OUT.
return;
}
textBox1.Text += Txt;
}
