Hello brother ! i think the problem is that instead of passing the
function name to the delegate object, u were passing the string Txt
argument thats y u were getting error. Please try following code, hope
this would help
if the problem still exists please dont hesitate to write


private delegate void appendToTextBoxDelegate(String Txt);
//or use delegate object
public appentToTextBox _appendToTextBox;

private void appendToTextBox(String Txt)
        {
            if (this.InvokeRequired)
            {
                //anonymous object approach
                this.BeginInvoke(new
appendToTextBoxDelegate(appendToTextBox), new object[] { Txt })
               //second named object approach
               _appentToTextBox=new
appendToTextBoxDelegate(appentToTextBox);
               this.Invoke(_appendToTextBox,new object[] {Txt});
            }
            textBox1.Text += Txt;
        }
