The problem, I envision, is when you integrate a keyboard with the scanner.
How can you differentiate between keyboard input and the input from the scanner? Is there a way to tell whether the input is from a scanner or the keyboard?
no there is no way to differentiate between a keyboard and scanner if the scanner is acting as a keyboard. If the scanner comes in via serial cable, then it is a set of data that your program needs to gather and deal with. In that case, the data is separate. For us, it's just a fast alternate keyboard that is used to enter specific information into one specific field. Once that information is entered, a script processes the bar code data and the cursor gets moved to another field where keyboard entries are done. Then when that set of data is saved, a new blank page gets created and the cursor goes into the field for the bar code data, and the scan process starts over.
