problem with #using <mscorlib.dll>

I'm learning how to use Microsoft Visual Studio 2005.

I try to include #using <mscorlib.dll>

but got this error when I compile

"fatal error C1190: managed targeted code requires a '/clr' option"

What is the problem? I tried MSDN but it gives answer that nobody understands

Have you tried reading the help files with the IDE? Being a MS version, it may give you an explanation, or better still, how you can solve the problem

The #using directive is specific to C++/CLR. You need to enabled C++/CLR in the project options.

Or if you want to go for normal C++, don't use #using.

Looks like you are trying to use a managed C++ library within unmanaged code.

If you programming in straight C++, and not in .NET, you cannot use that library.

I found the instructions on how to sset /clr on!

I got a problem, I need to control directories and this link is great http://faq.cprogramming.com/cgi-bin/...&id=1044780608

but it can only work in msvc++ 6, not on ms visual studio 2005. Anyone knows what is the problem?

but I use #using <mscorlib.dll>, which is in .net platform, then my code can't be run in msvc++ 6.

my problem is i need to be independent across the complier. thanks!

/clr is compiler-specific, so it's of course a big no-no.

Just follow the instructions in the other thread: install the PSDK and the API code will work in 2005.
