This is the JScript version of the IWMSPlayers::get_Count method. It is included for developers who are more comfortable with JScript syntax.
Example Code
#include <windows.h>
#include "wmsserver.h"
// Declare variables and interfaces.
IWMSServer *pServer;
IWMSPlayers *pPlayers;
HRESULT hr;
long lCount;
// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
NULL,
CLSCTX_ALL,
IID_IWMSServer,
(void **)&pServer);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to an IWMSPlayers interface
// and retrieve the total count of current connections.
hr = pServer->get_Players(&pPlayers);
if (FAILED(hr)) goto EXIT;
hr = pPlayers->get_length(&lCount);
if (FAILED(hr)) goto EXIT;
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
