#include <windows.h>
#include <atlbase.h>    // Includes CComBSTR and CComVariant.
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSNamedValues *pNamedValues;
IWMSNamedValue  *pNamedValue;

HRESULT         hr;
CComVariant     varIndex;
CComVariant     varValue;
CComBSTR        bstrName;
long            lCount;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,

// Retrieve a pointer to an IWMSNamedValues interface
// containing descriptive information about the server.
hr = pServer->get_Properties(&pNamedValues);
if (FAILED(hr)) goto EXIT;
