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:

(Toggle Plain Text)

#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(...):

(Toggle Plain Text)

DWORD WINAPI GetEnvironmentVariable(
  LPCTSTR lpName,
  LPTSTR lpBuffer,
  DWORD nSize
);

and use the return value in your program.

@Random-Spirit -- Here is another interesting idea...thank you for the help, but if you dont feel like responding, dont. I appreciate the help.

For Linux:

(Toggle Plain Text)

#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".
