using namespace error

Hello,

When I try to complie the following code i get :-

"error C2871: 'std' : does not exist or is not a namespace"
&
"error C2065: 'ofstream' : undeclared identifier"


#include "fstream.h"
#include "stdafx.h"
#include "afxinet.h"
using namespace std;

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{

ofstream logfile;
return 0;

}

TIA,
John D//

I am using VC++6 on NT4, with the latest service pack for VC & NT4

THX,

I think you should check out your understanding of the #include directive, in particular, the difference between...

#include "file"

...and...

#include <file>

I don't know if you have legitimate reasons for doing what you have done, I can only see the code you have posted, but it certainly looks to me as if you are using the wrong one.

Thanks for the reply.

I tried;

#include <fstream.h>
#include <stdafx.h>
#include <afxinet.h>

as well but still have the same problem.

John d..

do not use
#include "fstream.h"

the namespace std is used in the headers without '.h'

use
#include "fstream"

>>> #include "fstream"

#include <fstream>

Ok, Tried that as well with the same result.

the reason i was using namespace std; was to get around the original problem.

error C2065: 'ofstream' : undeclared identifier.

Am I doing something fundamentaly wrong here.

ofstream is part of a ftp app which compiles ok. It only when I try to use ofstream, I am getting compile errors.

John D..

reorder include files:

#include "stdafx.h"
#include "afxinet.h"
#include "fstream"

and if you include the 'windows.h' in your stdafx.h - comment it.

You need to use...

#include <fstream>
using namespace std;

Is that what you've got?

damyan:

Unless he has moved his standard include files, using the "file" version of the #include directive will not work.

Using

#include "stdafx.h"
#include "afxinet.h"
#include <fstream>
using namespace std;

has worked!! Im getting 3 warnings however

LINK : warning LNK4089: all references to "ADVAPI32.dll" discarded by /OPT:REF
LINK : warning LNK4089: all references to "SHELL32.dll" discarded by /OPT:REF
LINK : warning LNK4089: all references to "comdlg32.dll" discarded by /OPT:REF


But its compiling.

Thanks for all your help.

Okay, but...

>>>

... just blindly accepting a snippet that worked will not help you solve your other problem. This is for your own good - I'm not just being difficult. <file> and "file" are not the same, indeed <file.h> and <file> are not the same either.

Thats a fair enough comment. My back was against the wall at the time of posting. I needed to get something up and running very quickly.

Now that I have some spare time I'll be reading up on the include statement.

Thanks,
JohnD

its real simple really....

#include<> looks in the compilers standard include directory.
#include"" looks in your apps current directory
