Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan.

View 1 RepliesI am writing an inventory control application in which a barcode scanner will be hooked up to a laptop computer in our shipping/receiving department. What I'm wondering is, whenever a shipment comes in and the receiving clerk starts scanning the products, what exactly do I need to do in order to setup our database so that the scanner recognizes which vendor/product etc. and puts the data in the correct tables. I've written inventory control apps before but never one that incorporated the use of a barcode scanner.
View 8 RepliesSo i bought a cheap USB barcode scanner to play around with. So far pretty simple to use, on theing thats baffling me though is after the keyUp event and the string parsing, how do i reset the value of the textbox that reads the string to make it wait for a new keyup event. Eventually i'm going to try adding rows to tables and autocompleting cell values based on the parsed string. So what would be the best way to start looking at this?
