Example Code [C++]

The following C++ code example retrieves the Windows 2000 system information. For brevity, error checking is omitted.

#include <activeds.h>
#include <stdio.h>
 
int main()
{
   HRESULT hr;
 
   hr = CoInitialize(NULL);
 
	IADsADSystemInfo *pSys;
	hr = CoCreateInstance(CLSID_ADSystemInfo,
						NULL,
						CLSCTX_INPROC_SERVER,
						IID_IADsADSystemInfo,
						(void**)&pSys);
 
   BSTR bstr;
   hr = pSys->get_UserName(&bstr);
   if (SUCCEEDED(hr)) {
	printf("User: %S\n", bstr);
	SysFreeString(bstr);
   }
 
   hr = pSys->get_ComputerName(&bstr);
   if (SUCCEEDED(hr)) {
	printf("Computer: %S\n", bstr);
	SysFreeString(bstr);
   }
 
   hr = pSys->get_DomainDNSName(&bstr);
   if (SUCCEEDED(hr)) {
	printf("Domain: %S\n", bstr);
	SysFreeString(bstr);
   }
 
   hr = pSys->get_PDCRoleOwner(&bstr);
   if (SUCCEEDED(hr)) {
	printf("PDC Role owner: %S\n", bstr);
	SysFreeString(bstr);
   }
 
   if(pSys) {
	pSys->Release();
   }
 
   CoUninitialize();
   return 0;
}

Example Code [Visual Basic]

The following Visual Basic code example retrieves the Windows 2000 system information.
