Computer name w/C++

Hey guys,

I have a little program i created using c++. All the program does is runs a dxdiag on the local machine, then outputs the results in a .xml file on the desktop. Then code looks like this:

#include <iostream>



using namespace std;



int main()

{

    system("dxdiag /x jxdiagRESULTS.xml");

}

I need to save the file to a folder on a server with the computer name as the file name. Is there any way to find the computer name with c++?

Hmm here is an interesting idea, why not have a look on Google? Or better yet look at the Win32 api docs!

I will save you the effort (hardly any really).

In windows.h you will find an interestingly named function called GetComputerNameEx(…). I wonder what that could do?

You can look up the parameters yourself using the Win32 documentation on MSDN or your local copy of the docs either in a Platform/Windows SDK or MSDN distribution.

You can also use the COMPUTERNAME environment variable to get your name. Call GetEnvironmentVariable(...):

DWORD WINAPI GetEnvironmentVariable(

  LPCTSTR lpName,

  LPTSTR lpBuffer,

  DWORD nSize

);

and use the return value in your program.

For Linux:

#include <iostream>



using namespace std;



int main (void)

{

        char *x = getenv("HOSTNAME");

        cout << x << endl;

        return 0;

}

For Windows... the environment variable you want is "COMPUTERNAME".
