MS will take your money, if you send them enough. VB6 is still available via a developer subscription, but that's a pretty high price to pay.

I was going to ask about the VB6 IDE, since you seem to be one who likes it. I've felt that was the worst part about VB6 for almost two decades now. One code file at a time? No collapsing of methods? It's straight up awkward navigating that. Sure, you might be familiar with it, but you're still spending more time because of the IDE.

However, the point I'd rather make is this: If you know people who are staying with Windows XP, you should be strongly encouraging them to move on. That OS has some serious security vulnerabilities. Anybody who is using that, still, should be keeping it away from the internet at all times, or they are creating a wide open door into any network they have, or at least onto their own computer.

I realize that some people don't have the money to upgrade, but XP is something of an existential risk to a business.
