Thanks, again, a lot, in advance. Cheers, Jesús    Report

However, even these features can be used in 2 or mor different instances of the application at the same time with no problems (running from separate processes).

Maybe i've not formulated the question properly, because it regards an architecture that seems to be "very special". I apologize for that and i try to explain myself better. The scenario is the following: An ASP.Net-based web service creates, for each request to that service, an instance of the COM ReadBarCode classes and releases those instances when the operation is finished (the service's goal is to return the barcodes found in a TIF document). A JAVA-based application manages the requests for barcode reading by throwing each service request in a different thread. With that architecture, are simultaneous barcode requests processed in parallel regarding the LEADTOOLS component? Thanks a lot again, Jesús    Report

Also, loading TIFF images into LEADTOOLS supports multithreading too. If these are the only features you need (and you don't need OCR or PDF, for example), your application should work. However, I strongly recommend you test using the free evaluation edition of the toolkit before you build your actual application.   In case you want to support a feature that doesn't work with multi-threading, you could change your design so that every request is handled in a different process on the server instead of multiple threads in the same process. This way, even OCR and PDF should work. Qasem Al-Lubani LEAD Technical Support www.leadtools.com    Report
