Joe,
Microsoft deliberately took OUT some features which were needed by VB5. They also took OUT a lot of features from the VB language when they replaced it by VB.Net. No doubt to 'encourage' people to purchase new software. (They have also removed the previous version of the Help system).

My problem is not just a program that doesn't work, and can be replaced by a more modern version. It is 200,000 lines of program code (HARMONY) which would need to be rewritten before I can even compile it using VISTA. And it includes some OCX code from other authors which may not even work at all.

As I receive only a very little income from registrations, I cannot dedicate my personal time, unpaid, for the several months' hard work needed to convert it.

But when compiled under XP, the program actually runs perfectly on a VISTA machine.

How many other software writers have found their code made obsolete for no good reason other than to increase Microsoft's profits by having to purchase upgrades?
