Hi,

We would like to migrate our VB application (which is a project group contains 10 user control projects and a standard exe project). We cannot able to migrate the project group as a whole (or a usercontrol project) into vb.net.

While opening a vb user control (.ocx) project in VS.NET environment, we got the following error
"User control projects created in previous versions of Visual basic cannot opened in Visual Basic.NET."

How do we achieve this?
(or)
Is there any third party tool available to perform the migration?

Appreciate if you help us...

Thanks in advance

Jaba

I am sorry, but the Upgrade wizard can't upgrade the User control project
of VB6. Because of the lack of design-time support for UserControl projects
in VS .NET, the Upgrade Wizard will not be able to upgrade them. You can
still use them in your .NET applications, but you would need to maintain
them in VB6.

Although I would not recommend upgrading any Vb6 project to .Net  in any case.
Just rewrite them from scrach in .net it will produce better code than any upgrade could ever do.

I know this will probably be a lot of work but it will be worth it

Just a question what version of visual studio are you using. Because in version 2003 it should be possible to upgrade according to MS.

look here

PS. I would still recommend rebuilding them yourselve in .NET
