I've limited a field to the correct number of characters for a barcode but I want to ensure that users don't try to scan longer barcodes into that field as it wont be obvious that only part of the barcode is displayed.
I have code when saving the record to check the length of the field to ensure fewer characters are not entered, but how to I make the system bring up a message box or something when a user scans a longer barcode into this field?
