   enable/disable the keyboard , PLZ HELP!!!
  Hello, I am using barcode scanner through USB and I want to disable/enable keyboard. Is there any way to enable/disable the keyboard. Please help!! Thanks in advance...   
  Just don't check keyboard input? What do you mean by disabling it?   ;  I think you can drop a keyboard input interrupt handler on the Win32 kernel and then just filter input. I did it when I wrote my keylogger.Pretty sure the barcode scanner uses the keyboard API though, so dunno how you'd differentiate the two.
