from the datasheets of the barcode reader it seems that the data that would be sent to the pc would be alphanumeric in nature ....
I don't know much about barcodes, but I can't see why a 1D barcode cannot be read in either direction, and for the software to automatically figure out the value. However, I suspect that conventional barcode readers (i.e. with built-in intelligence) do not provide an indication of the direction of swipe, I suspect they just output the corrected barcode value, regardless of scan direction.
The trick would be to read two barcodes sequentially : )
firstly considering the train and the rolling stock that follow it how will i be able to tell my program that the trains have finished passing?? or that the last cart has passed??
secondly i am going to use the barcodes to literally just number the trains, but other train information i would like to display would probably be stored in a file of some sort and i would have to associate the information for each engine and cart to the corresponding barcode. how can i do this?? i am using visual studio 2010 and using visual basic programming language thanks
