This app shows you one way* of automatically generating a variety of 1D and 2D barcodes from your data. There are many ways of doing this and you can modify this app significantly to increase its power, but this should get you started... Have fun!
*Note that this app generates barcode images from a third-party tool, for which Quick Base is not responsible, and its functionality depends on that tool to work properly. If you experience problems generating barcodes, be sure to (1st) ensure the data you're trying to encode meets the requirements of the Barcode Type you've selected, and (2nd) inspect the formula in the 'Auto-Generated Barcode' field and modify as necessary, potentially to use different barcode source.
