Going From MFC to .NET

[Medical-Fix]

I hope someone can help me on this!
here is what's happening:
Big project created on MFC C++ with extensive GUI etc...
I tryed to open this project using .NET
and everything is fine from GUI to project settings etc...
Now the problem is that when I try to compile a debug or release vr.
the project gives the following error after successfully compiling all
of the other codes:

//**THIS IS JUST PART OF THE OUTPUT**//

I hope someone can help me on this!

Somebody in the relevant newsgroup from "microsoft.public.*" hierarchy
should be able to. I'd start in 'microsoft.public.vc.project_mgt'.

<ot>.NET offers such an improvement over MFC that, IMHO, this effort
sounds like a waste of time. If you or your company has the resources
to completely rewrite this application in .NET (presumably C#), then do
that; otherwise, learn to live with MFC. You won't be the only one.</ot>

Hi Bensen,

I couldn't figure out what you mean by the comment. You said ".NET offers
such an improvement over MFC, this effort sounds like a waste of time."
That sounds contradictory to me. However, I agree that this effort could
maybe not be worth the trouble unless there is something specific in the
managed code stuff in.NET that is needed. Just curious.

Ok here is what's happening...
I have opened the project "originally created MFC" using VC++ .NET
I got does errors for some reason unknown, I fixed other minor errors
and opened the project once more but on a different computer...
What u know! works!
it's something to do with my computer I gess and I can't figure it
out...
Perhaps some settings are wrong on VC++??

I thank you guys concerns and help...

I've had to fix minor errors in my code for every release. Lots of things
have changed since 6.0 (assuming that's where you are coming from) so some
upgrading pretty normal. Could be the other computer has some components
installed that you don't, etc. It might help if you post some of the errors
your seeing.

What I meant is that trying to open an MFC project with .NET sounds
much less fruitful than simply rewriting the project, assuming
resources are available.
