i tried to use this command but when i try to compile i get errors in ostream.h (cant name the english error but its something about elements having several meanings) what am i doing wrong? btw: i have several .cpps each including an includes.h which includes all the other .h s. when i remove all '#include includes.h' i only get other compiler errors resulting out of not having information about the classes. [edit1] im using std since my compiler does not seem to recognize the list<> class if i do not use std::list<> in the implementation [edited by - BB-Pest on December 4, 2002 3:39:10 PM]

i dont get the errot by including ... just by adding the line

'using namespace std;'

but perhaps the fault lies somewhere else... here's a part of the code:


    
#ifndef INVENTORY_H
#define INVENTORY_H

#include <'vector'> //without the ''
#include "Items.h"


// ...


/////////////////////////////////////////////////////////////////////////////

// Inventory


class Inventory
{
// ...

vector<InvNode> itemList;
// ...

};

#endif



but the compiler does not recognize vector.

try std::vector

or enclose everything by doing


#include <vector>
using namespace std;

In headers, it''s preferrable not to use the using namespace std (or any other namespace) directive because of namespace pollution issues. In your case, the code sample your provided neither uses namespace standard nor does it fully specify std::vector:

  
#include <vector>

#include "Items.h"

class Inventory
{
std::vector<InvNode> itemList;
};

thanks... both solutions worked.

now: is there any way to make my visual studio use the code-completing function. typing ''itemList.'' will not make the possible elements pop-up( neither for itemList[]. (should i use iterator instead btw?)).
