Chapter 10. Using Barcode ActiveX in IIS

You can create images through the Barcode ActiveX and send to the browsers. This section briefly discusses several technical issues involving web programming with the Barcode ActiveX.

With careful planning and design you can create high quality label and print from the browser, as illustrated below:

Two labeling samples are included in the default installation - one creates barcode images based on screen resolution. Another one creates barcodes under 203-dpi resolution. The sample files are located under \program files\morovia\barcodeactivex3.3\IIS [2] folder by default. Simply copy the files to an IIS virtual directory and you are ready to test.

With server side bar coding, all that a client computer need is to have an Internet browser and a printer. However, to create quality barcodes at the server end is nevertheless a nontrivial task. The HTML IMG statement was designed to display images on a computer screen. All browsers simply scale the image pixel to pixel at the time of print while retaining the overall size. A barcode image created targeting high resolution devices may deteriorate in quality when transmitted to a low resolution device.



[2] For barcode activeX lite, the folder is \program files\morovia\barcodelite3.3\IIS
