Kieran,
For most VB6 projects that I have seen I agree with Rob. ;-)
However there are a handful of VB6 project, I suspect more than most want to
admit, that can be upgraded!
There is a technique available to restructure code in a disciplined way
known as Refactoring
http://www.refactoring.com that allows you to
"rearchitect & redevelop an application" from the code that the upgrade
wizard converted. I've used Refactoring on two rather large VB6 projects
that were upgraded to VB.NET, both projects have hundreds of classes. The
first was a highly procedural (read no classes) VB6 app, the second was
already OOP in VB6. The first still has a lot of vestiges of VB6 as it is
highly monolithic and that code does not need to be converted, while the
second you cannot tell it started its live as a VB6 app, this
transformation, via refactoring, was not done overnight!
How much effort I need with Refactoring is highly dependant on how "clean"
your VB6 code is. By clean I am referring to if you used OOP practices in
your VB6, to the best that VB6 allows.
The VB6 Code Advisor helps with semantical changes from VB6 to VB.NET.
Remember that the upgrade wizard will leave your classic ADO code in place,
it will continue to function. That it will convert most controls that have
..NET equivalents, the others it leaves as OCX, which will continue to
function. What I do is use refactoring to replace these. Maybe not right
away, I may wait a month...
Just a thought

Lol oh well :) I had a feeling someone was going to say that but was
holding out for hope that someone had performed a miracle! Thanks anyway Rob.

I'm sorry for the bad news but the upgrade wizard software isn't that
useful. The problem is that Windows Forms Controls and ADO.NET are too
different from ActiveX and Classic ADO. There is also the fact that
VB.NET is fully object oriented while Classic VB isn't. It has been my
experience that you will almost always be better off to rearchitect and redevelop
an application than to try to upgrade it using the wizard.

I'm just looking into this for my boss (and myself I suppose). What is
the current state of VB6 to VB.NET converters out there and what are they? I'm trying to convince our company to convert its primary product over to .NET but our primary project is pretty huge (many forms, lots of db work,
lots of CR9).
Any suggestions are helpful,
Thanks,
Kieran
