converting to studio 2003 en 2005

[marco 2]

hello all,

is it possible to convert a visual studio 5 or 6 project/workspace
in one go to 2003 or 2005 withou errors.
i have tried it but i received several errors.
one of them was: cannot find iostream.h.
when i had inserted iostream manually,
from a former version of studio,
i received 23 errors while my project was errorless
in vstudio 6.

It's not a conversion issue (which would have been off-topic here, so
you're lucky that it isn't!), it's an error caused by your project
using a header file that doesn't exist in standard C++ - iostream.h.

Visual Studio 5/6 had a header file named iostream.h for compatibility
with older code. However, you should #include <iostream>, not #include
<iostream.h>. Remove the .h and you won't have any problems.

You also need to add this line after the #include directives:

using namespace std;

You need to do no such thing. Bringing in the whole of std into global
scope is generally considered a bad thing to do. I think that Tydr
Schnubbis should ask himself why things are done before he suggests
doing them.

Your existing code probably references everything it needs from std in
its own way - you don't need to add this pointless line unless your
compiler complains (in which case you should consider more sensible
namespace resolution).

Nice save!

Yes it is!!

Try

# include <iostream>

Well, that depends what the errors are.

VS 2003 and 2005 are much more c++ compliant than VC6, which was
released before the standard was finished.

Assuming this is being done in non-header files, it is better to put

using std::cout;
using std::cin;
using std::ostream;
using std::istream;
using std::endl;

as required. If you're very lazy then write a header file, maybe call
it iostream2.h, and put all that in there.

That's for a quick fix though.

Even better, given that you are working in an environment with global
find and replace is to replace all instance of cout, cin, ostream,
istream, endl (match whole word only) with std:: in front. And then you
can also replace any std::std:: with std::

Excuse me? W Marsh did NOT write this! W Marsh said it was a /bad/
idea to do such a thing. You've somehow mixed up my name with Tydr
Schnubbis' name.
