|Why use a batch file. Every Windows programming language have seen has the facility to record, disply and automatically update the version number. It is stored within the programme, no need to put it into a separate text file.|
All; you need to do it is write a short routine that checks the version running and compares it with the latest version and then prompts for an update if required ech time the programme is run. You must have seen commercial programmes do it, it is a simple thing to do.
