1. How to solve this in msvc6 ?
#include <iostream>
std::vector<int> v;
tests.cpp(43) : error C2039: 'vector' : is not a member of 'std'
2. How to call to the constructor of a base class from the constructor of a inherent class ? and how to call to the constructor of a class, from the copy constructor of the same class ?
3. Is still useful the use of malloc/free in C++ ? or its "good-way" only use new/delete?
4. There is a way in msvc6 or 2003 to automatize the creation of a new file with some code? I mean: when you create a .h file, of name Texture.h, automatically, it creates the base code:
#ifndef _TEXTURE_H_
#define _TEXTURE_H_
class Texture {
private:
public:
Texture();
~Texture();
};
#endif
and when you create Texture.cpp, it creates:
#include <Texture.h>
Texture::Texture() {
}
...
thnx (I believe that I will go on)
1. #include <vector>
3. You can still use malloc/free, but new/delete are considered "better" for some uses. Here's the FAQ entry for it.

class A{ A(const std::string& n) : name(n) {}; std::string name};
class B{ B(const std::string& n) : A(n) {}};
class A{ A(const std::string& n) : name(n) {}; std::string name};
class B{ B(const std::string& n) : A(n) {}};

To some extent you can.
You can supply a template file to VS 6 that it will copy to your new file, and/or you can write a macro to do it.
I use VS .NET, and the file goes in Vc7\vcprojectitems and has to be named correctly. I don't remember exactly where you put the template file in VS 6.
Here is the macro I use. I create an empty file and name it, and then run this macro on it:
''' Adds a generic file header based on file type ''' Sub AddFileHeader() Dim ext As String Dim fileIsIncluded As Boolean Dim symbol As String Dim ext_pos As Integer = InStr(DTE.ActiveDocument.Name, ".") If ext_pos = 0 Then ext = "" Else ext = Mid(ActiveDocument.Name, ext_pos) End If fileIsIncluded = False If ext = ".h" Then symbol = UCase(Left(ActiveDocument.Name, ext_pos - 1)) + "_H_INCLUDED" fileIsIncluded = True ElseIf ext = ".inl" Then symbol = UCase(Left(ActiveDocument.Name, ext_pos - 1)) + "_INL_INCLUDED" fileIsIncluded = True End If Dim sel As TextSelection = DTE.ActiveDocument.Selection sel.StartOfDocument() Dim point As EditPoint = sel.TopPoint.CreateEditPoint() DTE.UndoContext.Open("Add File Header") Try Dim blank_line As String = " " Dim blank_len As Integer = Len(blank_line) Dim name_len As Integer = Len(DTE.ActiveDocument.Name) Dim left_len As Integer = Int((blank_len - name_len) / 2) Dim name_line As String = Left(blank_line, left_len) + DTE.ActiveDocument.Name point.Insert( _ "/** @file *//********************************************************************************************************" + vbLf + _ vbLf + _ name_line + vbLf + _ vbLf + _ " Copyright 2004, Your Name Here" + vbLf + _ " --------------------------------------------------------------------------------------------------------------" + vbLf + _ vbLf + _ " $Header: $" + vbLf + _ vbLf + _ " $NoKeywords: $" + vbLf + _ vbLf + _ " ********************************************************************************************************************/" + vbLf + _ vbLf) If fileIsIncluded Then point.Insert( _ "#pragma once" + vbLf + _ vbLf + _ vbLf) End If If Not ext = ".h" Then point.Insert( _ "#include """ + Left(ActiveDocument.Name, ext_pos - 1) + ".h""" + vbLf + _ vbLf + _ vbLf) End If Finally 'If an error occured, then need to make sure that the undo context is cleaned up. 'Otherwise, the editor can be left in a perpetual undo context DTE.UndoContext.Close() End Try End Sub

thanks very much for help and links ! especially the vb macro,I have changed it and now works very well for me (and I have learned a bit vb :) )
