Check for Updates

We have a number of customised applications in accounting and finance written for clients. During the customisation process we have to manually update user machines with the latest application. Sometimes it is not possible to access all the machines so it is possible for user to be 3-4 builds behind the current application and this causes support concerns. Using VB6 SP6 we need a sample application written than checks what the latest Build number is (we use the automatic Build number generator) from a server folder setup to house the updates.? If the application? finds the client machine's version is older than latest release it will prompt the user to update their application now. If the user says YES the application is updated and then launches. This a sample application to demonstrate the process so must be well documented in the code so we understand what the code is doing in the process. Once we understand the sample application we will? include the code into our application.
