This question gets asked a lot ... in fact I gave a
lengthy explanation about this
issue in a previous Ask The Expert tip. And although
I can't comment on C++,
it is easy to take Visual Basic code
and import it into Visual Studio.NET. You can simply
open the project as you would
in Visual Basic 6.0. When you do, an Upgrade Wizard
appears to walk you through the
process. The Upgrade Wizard will make changes in much
of your code to make it .NET
compliant and save it into a new project so that your
original source code will
not be changed.
However, this process will only get
you 60% to 90% of the way there, depending
on the quality of your code. The Upgrade Wizard
produces a report of To Do items that you will need
to manually address.
Is it better to re-write? That
depends on your project. If you
are dependent on many third-party controls, COM+
components, etc. then you will probably
want to re-write to take advantage of .NET's features
and move away from "unmanaged" code.
