Research And Application On The General Barcode Print Technology Based On B/S

The current information system architecture are the B/S transition from C/S, automated data entry function information system is mainly achieved through barcode technology. Using barcode technology for fast data entry first step is to print data into barcodes, however, due to the B/S structure itself and the characteristics of the client printer differences, so that in the B/S architecture barcode printing has always been a difficult unified complex problems; Therefore, in order to shield the printer to make up the difference and B/S architecture insufficient in this regard, under the B/S architecture general barcode printing has become a hot issue for researchers. Aiming at these problems, combined with the detection chamber Anhui gold jewelry item " Anhui gold jewelry testing management system" to study, study include the following aspects:(1) Research and implement ActiveX controls printing technology. ActiveX controls are currently the mainstream print barcode printing technology, but cannot achieve unity barcode printing. Research and implementation of this method by further clear demand barcode printing.(2) Research data conversion method barcodes to propose a barcode data into new ideas, no longer using existing conversion tools, but needed to prepare the corresponding algorithm conversion.(3) Study the problem of existing generating position bar code printing technology, the proposed location of the barcode to generate server-side, shielding the client generates barcode differences.(4) Combined with (2), (3) two points difference presents a generic printer can shield barcode printing method " instant barcode image " method, and use Crystal Reports to implement this method.(5) A combination of these work, develop to achieve " Anhui gold jewelry testing management system".Currently " Anhui gold jewelry testing management system" has been used in gold jewelry testing laboratory Anhui running up to a year, and extended to the other two testing organizations to use, the system is stable, the customer experience better.
