“Alan Ford”: Very disillusioned by M$oft’s pulling the plug on that. Visual dot.net is nothing like vb6. (and the vb6 IDE does not work on Windows 10). Probably moving to Linux. I would like a language as near as possible to vb6. It must have the following."
We are in the absolute same situation. I have already 17 years with the VB6, I have a big medical project written in VB6 with many clients, so I have to go on with it. If I want to have 1-2 years to rewrite them now, starting from “white screen”, then I will loose all of my clients, so this is a trap. With frequent updates my softwares have a fresh look, they does a good and user friendly job, so from the aspect of the clients (doctors, nurses in outpatient departments) is not a matter what is under the hood. It works good? Yes. Will it works? Yes, Microsoft promise support (= VB6 can run) till ca 2025 under the Windows10 life-cycle. So VB6 lives and can live with us in the future.
But, the world is changing. VB6 can do the job on the Windows, but the clients want to see new, online, web based solutions, they want to use phones, and this is the real shortage if we stay with the Vb6. In the “good old days” (1999-2002), internet was not a real factor, but now it is.
I have checked .NET, but I leave that fast. No Vb6 migration tool??
Shit. Huge company, I admire them, but this case with the VB6 was so primitive and amateur… I can’t trust in them anymore. My first new hope was JABACO (http://www.jabaco.org) which was a very intresting project, a very smooth possible transition from VB6, with the same IDE, same languange parts, BUT it stucked in beta phase, the young developer disappeared, wrote sometimes in the forum that he comes back, but not. Perhaps got a new job in the Microsoft. 
Nowadays I have tried the B4j language, but this is also a typical “one man” company, with a very dedicated and helpful guy. In his advertisements wrote he that this is real Vb6 alternative. It is not! This is a very complicated language, primitive IDE with very much shortages, and its “Visual Designer” is a totally failed concept. I had a half year with it, but it didn´t work for me.
And now came Xojo, and I am very positive with it. When I open the Xojo, I feel myself “home”. As Horacio Vilches also comments here, “I can assure you Xojo is the best for people who have a VB6 brackground.” Yes. The languages is partly very similar with the Vb6, so I could get much positiv feedbacks after only a few hours with the Xojo. I develop now new Xojo webapps to my main Vb6 project, for example an online patient booking calendar system.
But I see also that Xojo is not Vb6, and I hope that Xojo can be better. For example in the Vb6 it is much better to see the whole source code, here in the Xojo I must jump too much and I can see always only a little part of the code on the screen. Or for example in the VB6 is more easier to change the background color, fontsize, etc of an object, without theese (and for me little crazy) “styles”. But Xojo is the best alternative, and it works.
