title: Directly Capturing Multible USB Barcodes in Delphi
body: <p>I just finished coding a USB relay board to open and close 2 relays. First time doing any kind of .DLL programming. But now I need to code two USB bar code scanners on the same PC.</p>
  
  <ol>
  <li>First I need to know which one of the scanners is being scanned.(I'm calling it -scan in/scan out)</li>
  <li>And Secondly I need to capture the string to check against a database, but doing this without the scanner influencing any other program running, like if I'm focused on notepad while scanning, no text should appear on notepad. </li>
  </ol>
  
  <p>Any info will be appreciated and Some Sample code even more.  </p>
