#using namespace std;

This is a discussion on #using namespace std; within the C++ Programming forums, part of the General Programming Boards category; I just tried to test something in M$_DOS, and as usual i do: Code: #include <iostream> #using namespace std; int ...

    #using namespace std;

    I just tried to test something in M$_DOS, and as usual i do:
    Code:
    #include <iostream>
    #using namespace std;
    
    int main()
    {
        //CODE HERE
        return 0;
    }
    then i compile and get 2 error, pretty good i though, but then when i saw the error:
    Code:
    test.cpp(2) : error C2006: '#using' : expected a filename, found 'namespace'
    test.cpp(2) : fatal error C1190: managed targeted code requires '#using <mscorlib.dll>' and '/clr' option
    Maybe its just cuz im a bit dusty on this stuff, but im pretty sure thats how i use to do it?

    Am i spelling something wrong? Did things change?
    Why am i getting an error? how do i get rid of it?

    using is not a pre-processor command and therefore is not preceded by a #. A console program is not an MS-DOS program. MSVC.NET can not create MS-DOS programs.
