I want to write incoming and out going messages to the UI Form. But when i am calling BeginInvoke method. it is showing exception message
"Invoke or BeginInvoke cannot be called on a control until the window handle has been created."
and Invoke required method is not being set to true, which should be set when calling method from another thread.
I am using following code.
if (InvokeRequired)
{
object[] pList = { message };

Txt_RecievedFrmCOM.BeginInvoke(new WriteLineDelegate(WriteFix2), pList);
}
else
{
WriteFix2(message);
}
So can any one help me and let me know that how can i Update it to the textbox on UI Form.
Thanks In Advance.......... Please reply........

Not familiar with the method, but you misspelled "received" and that may affect it.
