While the script is running, the scanner can send another code to the computer, but it will be ignored until the script returns the cursor to the field. At the end of each processing, the script clears the field and then selects the field, in anticipation of the next scan. The script in PassTracker uses a global field for the barcode scan. That computer can be setup to always be in the right field and in the right mode, ready to execute any scripts setup to react to the barcode. If the project can justify it, the best possible solution is the purchase of a dedicated computer to receive the barcodes. This is where a dedicated computer for the barcode scanner can be useful.
If the cursor is in the wrong field, gibberish will be entered into the wrong fields, potentially corrupting data. Imagine that fast typist banging away on the keyboard, if no field is selected, FileMaker Pro will simply beep for each keystroke sent. One way to visualize a barcode scanner is to imagine it as a very fast typist entering a code into the computer. Inbound – Bringing Barcoded items back into FileMaker Pro batch printing on business card stock, to issue identity cards etc.outputting to a label printer on sticky labels to apply to equipment.Place this field on a label field layout and print out a set of bar code labels. Create a calculated field that wraps your serial number field with a star at either end of the field and set it to use the barcode font for display purposes. Barcodes require a beginning and end character, usually the star character on your keyboard: ‘*’. This serial number field will be the basis of your barcode field. In the FileMaker Pro database, create a serial number field. Install the font on the FileMaker Pro computer, (here are a couple of ‘how-to’s’ on installing fonts on Windows and Macintosh) so that it can be selected, in the same way that fonts such as Helvetica or Times, can be applied. Outbound – Sending Barcoded Items out into the World from FileMaker Pro Optional – A dedicated computer to scan in the barcodes.A FileMaker Pro database system setup to create and input barcodes.To employ Barcodes with a FileMaker Pro system, three or four things are required: No demo file this time, but hopefully the overview will get you started and through most of the major hurdles. I was able to provide him with an overview of how to do this and thought it might be worth repeating for anyone wanting to get started with barcodes. I have setup a FileMaker Pro system called PassTracker that employs barcodes to keep track of membership activity at gyms. I had a discussion recently from someone wanting to know how to setup FileMaker Pro with a barcode scanning system.
