public void GetText()

        {

            if (Clipboard.GetText() != null)

            {

                newget = Clipboard.GetText();

                if (newget != lastget)

                {

                    txtClip.Text = txtClip.Text + "\r\n" + newget + "\r\n";

                    lastget = newget;

                }

            }

        }
