Reading serial barcode scanner in c#

[pranavkrish]

I am using serialPort control to read data from a barcode scanner , Can you please suggest me the most reliable methof to do this. Now I generate an even based on the data received in the serial port :

private void serialPortS2_Da taReceived(obje ct sender, System.IO.Ports .SerialDataRece ivedEventArgs e)
{

this.Invoke(new EventHandler(Do Update));

}


private void DoUpdate(object s, EventArgs e)
// private void DoUpdate()
{
toolStripStatus Label1.Text = "Reading Serial Port";
string sTCRead = serialPortS2.Re adExisting();
comboBoxTransmi ssion.Text = sTCRead.Substri ng(0, 10);
Transmissions.A dd(comboBoxTran smission.Text);
CheckForRework( );

}

If I run this with a break it works fine but the received data is not in full if I run without break, can any of you suggest me how do I hold till the complete data is received ?
