TBarCode .NET in an IIS 7.0 Web Farm

If you use TBarCode ASP.NET Web Control in a Web Farm you may encounter the following exception:

  • Exception Type: System.ApplicationException
    Message: The requested image is no longer cached.

The TBarCode ASP.NET Web Control uses the HttpContext.Cache object to store the generated barcode image. Since http requests are load balanced within a web farm it can occur that a specific Web Control receives a request for an image, which has been generated on a different application server (and therefore is not available in its local cache).

To overcome this problem you could:

  • Synchronize the HttpContext.Cache object on all servers in the web farm (distributed caches). This could be done with extra programming or additional third party software.

  • or simply use Client Affinity in IIS 7.0 (recommended)

Having client affinity enabled all requests are tagged with a cookie so that subsequent requests (from the same client) are routed to the same server in the web farm.

Details see Application Request Routing (3 - Configure Client Affinity)

Reporting Software - The Release Candidate is Coming!

I would like to announce a new version of TEC-IT's barcode label and reporting software TFORMer.

What is New in V6.0.1?

  • Brushed up User-Interface
    We updated the development environment to Visual Studio 2008. Thus, the features of the new Microsoft Foundation Classes are integrated into the report designer wherever it makes sense. And yes - it looks (& feels) good ;-)
  • Splitted Setup
    TFORMer consists of TFORMer Designer (a visual layout editor with instant label and form printing functions) and a reporting SDK which is named TFORMer Runtime. We introduced separated setups in order to reduce the download size of the package.
  • Update Checker
    TFORMer Designer now offers a function to detect the availability of a software update. You can trigger the update-check manually (Help menu).
  • Bug Fixes
    Finally, some major and minor bugs were fixed: among them are a multi-threading problem in the report generator SDK, improved image compression for PDF output, improved JAVA interface, etc..
Check out this blog for the download. Most likely the release candidate V6.0.1 will be available next week. I attached a screen-shot as teaser, it shows TFORMer Designer with the German user interface.

New Version! Barcode DLL for SAP

TEC-IT is proud to announce the new version of TBarCode/SAPwin - Barcode DLL for SAP!

TBarCode/SAPwin is a so-called barcode DLL for SAP ERP systems. It offers device and release independent bar code printing for all printers. Costly special purpose printers or barcode extensions like barcode DIMMs or barcode SIMMs are no longer required. TBarCode/SAPwin integrates seamlessly into the SAP printing process and operates as plug-in for SAPsprint or SAPlpd.

Users of TBarCode/SAPwin benefit from a minimal cost of ownership. The transparent licensing scheme enables customers to put a cost effective bar-coding solution into operation. In addition, this barcode dll works with virtually every printer available on the market.

The new version of TBarCode/SAPwin focuses on Unicode capabilities (e.g. for SAP ECC 6.0), on Windows Vista and Windows 7 compatibility and provides the most complete barcode support available on the market. Linear bar codes like EAN128, HIBC codes, 2D bar codes like Data Matrix ECC200 and even the GS1 DataBar symbology are generated and printed in perfect quality. Installation and customization is easy - the product is configured solely via standard print controls. Existing Smart Forms, SAPscript or ABAP reports are usable without modification.

The solution is available for Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista and Windows 7. Download the free demo version: TBarCode/SAPwin V9.
