problem retrieving domain name [modified]

Moonis Ahmed

hi, i am trying to retrieve domain and user name by the following code

#include "windows.h"

LPTSTR lpszSystemInfo; // pointer to system information string
DWORD cchBuff = BUFSIZE; // size of domain name
TCHAR tchBuffer[bufsize]; // buffer for string

lpszSystemInfo = tchBuffer;

// Get machine name
if( GetComputerName(lpszSystemInfo, &cchBuff) )
m_machineName = _bstr_t(lpszSystemInfo);

// Get domain.
cchBuff = BUFSIZE;
if (GetComputerNameEx(ComputerNameDnsDomain, lpszSystemInfo, &cchBuff))
m_domain = _bstr_t(lpszSystemInfo);

// Get user name.

cchBuff = BUFSIZE;
if( GetUserName(lpszSystemInfo, &cchBuff) )
m_osUsername = _bstr_t(lpszSystemInfo);

This is a part of the code. When i compile it, I get the following error: error C2065: 'GetComputerNameEx' : undeclared identifier error C2065: 'ComputerNameDnsDomain' : undeclared identifier Can anyone help me solve it? Moonis -- modified at 21:39 Sunday 3rd June, 2007

Please put any code inside < pre>< /pre> tag to view it correctly. Before including you should define _WIN32_WINNT greater than or equal to 0x500;

#define _WIN32_WINNT 0x0500
#include <windows.h>

You have to define the _WIN32_WINNT version to 0x0500 or greater. for this Take project settings->c++->Preprocessor definition. In that edit box add _WIN32_WINNT=0x0500

Hi, In the msdn documentation for GetComputerNameEx it is given "To compile an application that uses this function, define the _WIN32_WINNT macro as 0x0500 or later" have to confirmed it and it required to include windows.h

Hi, I did the above settings to enable the macro but the problem still persists.:sigh: My modified code is here:

#define _WIN32_WINNT 0x0500
#include "windows.h"
#include "stdio.h"
#include "iostream.h"
#include "tchar.h"

int main()
{
LPTSTR lpszSystemInfo;// pointer to system information string

DWORD cchBuff=sizeof(lpszSystemInfo);// size of domain name

// Get domain.
if (GetComputerNameEx(ComputerNameDnsDomain, lpszSystemInfo, &cchBuff))
cout<<"Domain Name is : "<

I am new to VC++ programming so please point out any other errors if there are.
