Version Tracker is a system for making sure users of your application always stay up-to-date. You just use tha Version Tracker server-side ASP script to list what available versions of your product you have. Then, your Visual Basic or ASP application can use the Version Tracker client-side component to check and alert the user if an update exists. The Version Tracker server script publishes available versions as an XML document (sample), so it can be extended onto languages that we haven't covered.
