What should do a VB 6. Developer

I was in VB 6 during early 2000. So once you moving to thin client form thick client, 1st step is to skip any tools/languages but understand the base technologies behind it. It's the most important step.

 

For example people mostly worked in VB6.0 and very 1st time trying any web development, they feel crazy by seeing data lose after each post back and they couldn't understand this state loss in web applications. But if you know how desktop(client/server) technology and web technology varies, you can understand such behaviors. So I would suggest to take maximum technology comparison between desktop application and web applications, before any tools/languages
