title: Standard Way to Read Data from USB Bar code Devices C#
body: <p>How can i read data from USB bar code devices in <strong>a read only</strong> text box field in c#?</p>
  
  <p>All possible ways to read from bar code devices work just like a standard keyboard device which means that text box field must be enabled &amp; editable.</p>
  
  <p>Is there any standard way to read data from any USB bar code devices (like TWAIN &amp; WIA for imaging devices)? or i have to get the SDK for each bar code device to deal with the device via virtual Serial port?</p>
