'std' is not a class or namespace name

[ruud79]

Hi,

I have just started programming using microsoft Visual C++ 6.0.

I want to use Vector and String in my code and so I included <vector> and <string>, but I get the error message &quot; 'std' : is not a class or namespace name &quot;.

The code looks like this:

include# <string>
include# <vector>

void CDataAnalyserView::OnFileLoad()
{
CFileDialog dlg(true);
dlg.DoModal();
if (dlg.GetFileTitle() != &quot;&quot
{
std::string filename = dlg.GetPathName();
}
}

I've read there is a bug in Visual C++ 6.0 that the namespace has not been defined and to work around the problem <cstdlib> should be included in namespace std like this:
namespace std
{
include# <cstdlib>
};

Maybe this is a stupid question but where do I put this code?

change
include# <string>
include# <vector>
to
#include <string>
#include <vector>
and
include# <cstdlib>
to
#include <cstdlib>

Sorry, this was a typing mistake in this thread. In the code I have put it down correctly.

Are you sure? The above mentioned includes should indeed solve your problem. It works for me at least...

/Per

_{if (typos) cout << &quot;My fingers are faster than my brain. Sorry for the typos.&quot;;}

I'm sure.

I included these header files like this now:

#include <vector>
#include <string>
#include <cstdlib>

The line where it gets the error is:

std::string filename = dlg.GetPathName();

The error message:

'std' : is not a class or namespace name

 

[Cagliostro]

are you using VisualC++ or BorlandC++?

is std::string filename = dlg.GetPathName(); a single place where you use name std?

ok, I think I have got your trouble.
Try to change
#include <vector>
#include <string>
#include <cstdlib>
to
#include <vector>
#include <string>
namespace std
{
#include <cstdlib>
};

Thanks.

I tried this, but now I get a different error message:

'string' : is not a member of 'std'

 

[Cagliostro]

try this:
namespace std
{
#include <cstdlib>
};
#undef _STRING_
#include <vector>
#include <string>

this one also could solve:
namespace std
{
#include <cstdlib>
};
#if !defined(__cplusplus)
#defined __cplusplus
#endif
#include <vector>
#include <string>

by the way, take a look into headers, if you are attentive, #include<string> also winn include #include<cstrlib>
