Involve [Invoice Alive]

Suppliers can also submit bulk invoices as an Excel spread sheet. Invoice application has upload facility where a user can upload the invoices in an excel file to the server. An NT service written in Visual C++ processes the excel file and creates the invoices using the same set of VB COM objects (code reusability). Should there be any errors a email notification is sent to the vendor indicating the errors in the excel file and the excel file is sent back as an attachment. Another NT Service written in C++ creates and manages the NT user accounts (each vendor ID is an NT user at IIS Server). The service reads a flat file that contains a list of vendors that need to be created or removed. NT Services were used as they can be configured to run on Start up of the server and allow the flexibility to endow some users with special privileges. XML was used to store the vendor preferences and customizations. INVOLVE was developed in Active Server Pages, DHTML, Java Script and utilizes COM, MTS and XML technologies extensively.
