IWMSPlugins::get_length

The get_length method retrieves the number of IWMSPlugin interfaces contained in the IWMSPlugins collection.

Syntax

  HRESULT get_length(
  long*  pVal
);

Parameters

pVal

[out] Pointer to a long containing the number of plug-ins.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code Number Description
E_POINTER 0x80004003 pVal is a NULL pointer argument.

Remarks

This is the JScript version of the IWMSPlugins::get_Count method. It is included for developers more comfortable with JScript syntax.

Example Code

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSPlugins     *pPlugins;

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 IWMSPlugins interface
// and retrieve the total count of plug-ins.
hr = pServer->get_EventHandlers(&pPlugins);
if (FAILED(hr)) goto EXIT;
hr = pPlugins->get_length(&lCount);
if (FAILED(hr)) goto EXIT;

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
