I advise you to steer away from any tool that does code-generation. They tend to get you 90% of the way there quickly - but the other 10% can be very difficult. How much code is in your existing classes? If your code is well segregated - you have taken care with "seperation of concerns" - then you should be about to drop in a new data layer solution. Our ORM tool Diamond Binding[^] is highly suited for creating and maintaining the business object definitions from an existing database, and providing a fully featured API for handling business objects. It also is powered by NHibernate. Mark Churchill Director Dunn & Churchill Diamond Binding: Zero to Data Layer in 3 mins

Oh yeah, just create a setup project and modify registry. I done :) . Thx you. imagic

Yeah I know what you're talkin about. That tutorial doesn't really cover it... you need to look into the technical documentation and figure it out yourself, building on your knowledge of toolbars and context menus in standard forms, combine that with what you know about Add-ins, and figure it out. This is an advanced topic and you will not find an article that simply tells you how to do it. This is where programming gets fun... embrace the problem and dive into it and figure it out as you go along. Nobody can help you do that. It is going to take hours, maybe days, of research, study and experimentation. The subject is difficult, and you are going to have to do a lot of work to figure it out. Accept that and stop asking for someone to hand-hold you through it. Dig in and get to work. I would help you if I could, but I can't move your fingers for you... Everyone else ignored this question... you need to think about why. I answered it because I like to bitch at n00bz.
