How to differentiate the Input from a Barcode reader and the keyboard?

Dear all,

can anyone propose a strategy how to deferentiate a keyboard input from the barcode reader. The reader in Windows acts like a keyboard in principle.

The idear behaind is the following: In the writen program there several input fields. A data from the scanner has to be added ONLY in defined input field while in others from the keyboard. Now it works wrong, since the data from the scanner (when operator clicks on the scanner) goes in the field where the last input was (a last position of a cursor).

I woudl be very grateful for any Idears how to make this deferentiation!

Thanks

Hi Sergii,

I understand that you need to distinguish between input from a barcode reader and a keyboard, which will allow you to update the required fields accordingly.

To achieve this, you can configure your barcode scanner to include an ‘untypeable prefix’ to the scanned text. By checking for the presence of this prefix in the input text, you can determine whether it originated from the keyboard or the barcode scanner.

An ‘untypeable prefix’ can be any text or symbol which has very less probability of being manually typed using the keyboard.

Hope this helps!
