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.
