Lock Inputbox

Hi All,

I have a simple script which uses an inputbox to prompt the user for a lot number. The inputbox is populated using a barcode scanner when they scan a barcode on their documentation. What I want to do is prevent them from changing that scanned value or manually entering one.

Can you please advise on how I could do this.

Not sure. Although, (brainstorm) you could accomplish this if there was a way to append a carriage return to the scanned barcode before it populated the input box. Or, you could disable the keyboard.

Is it easy to disable the keyboard?

Relatively. As the following post suggests, you will need to download and register the AutoIT dll. After that, it's only a couple of lines.

Assuming that the barcode scanner operates as a 'keyboard emulator' this may have unintended consequences. I went through a similar issue with a card-swipe reader. Appending a carriage return after the read didn't help either as that only works if a read occurs and does not prevent users from typing in the box without using the scanner.

Short answer, if the scanner is indeed a 'keyboard emulator' there is probably no way to do what you want short of physically disconnecting the keyboard and hiding it in the janitor's closet. (Users never look in the janitor's closet.)
 
Oh and by 'unintended consequences' I meant of course that it would disable the scanner as well as the keyboard.
 
Perhaps an easier way would be to use an HTML inputbox, effectively you would be creating a mini HTA application. Worth considering maybe?
