title: How can i restrict windows form textbox to read input only from my USB barcode scanner?
body: <p>I'm developing a application where user needs to get input from Barcode scanner.
  Its a usb type which scans and returns data in seconds.  </p>
  
  <p>I tried to stop getting input from Keyboard by many techniques</p>
  
  <p>Made my textBox read only But failed to get input from reader </p>
  
  <p>Managed keypress event But barcode reader actually acts as a Keyboard so i couldnt able to get required output  </p>
  
  <p>I need to Know is there any way to limit user with a particular time for providing input in textBox of windows forms or restrict user from providing input only from particular port?</p>
  
  <p>I use code <code>128symbology</code> for generating barcode.</p>
