Using VS2005 on a project that earlier used VS2003

[TonyJ]

Hello!

What is the right way to go when I have a C++ project that earlier used
VS2003.

When I compile now I get a lot of compile error.

Hi Tony,

Hello!

What is the right way to go when I have a C++ project that earlier used
VS2003.

When I compile now I get a lot of compile error.

Managed or unmanaged C++?

For managed: learn the new syntax for C++/CLI and change the code.

For unmanaged: what are the errors? Typically you will get a lot of warnings
about unsafe APIs which you should replace with safer versions.

Are you getting errors or warnings? Or both..
Please send a sample of the errors and warning you get.

You should be able to migrate from 2003 C++ projects to 2005 C++
projects fairly easily, but it depends on how compliant your C++ code
was.
Do you have any managed code in the C++ project?

Are you using many of the older C style functions? (such as ones found
in stdio.h). Using these will often give you warnings. Sometime you
can simply disable these warnings for the time being.

Hello!

It's manage code.
Is the best or maybe the only way to take each compile error and correct it.
I just wonder if there exist some way to let the vc2005 behave like vs2003
and compile without error.

/clrldSyntax might help (although I never tried it as I upgraded from
Managed C++ to CLI/C++).

Hi TonyJ!

It's manage code.

You have three chances:
1. Set your compiler option to "/clrldsynatx"
2. Review your code line-by-line
3. Use the "VC++ 2003 Managed Extensions to VC++2005 C++/CLI Conversion
Tool"

I would prefer the option 3
