IWMSAccessControlList::get_length
The get_length method retrieves the number of IWMSAccessControlEntry interfaces in the IWMSAccessControlList collection.
Syntax
HRESULT get_length( long* pVal );
Parameters
pVal
[out] Pointer to a long containing the count of interfaces in the collection.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
Remarks
This is the JScript version of the IWMSAccessControlList::get_Count method. It is provided for developers more comfortable with JScript syntax.
| Return code | Number | Description |
| E_POINTER | 0x80004003 | The pVal parameter is NULL. |
Example Code
#include <windows.h>
#include <atlbase.h> // Includes CComVariant.
// To access system plug-in interfaces, the
// entire type library must be imported as shown.
#import "WMSServerTypeLib.dll" no_namespace named_guids \
raw_interfaces_only
// Declare variables and interfaces.
IWMSServer *pServer;
IWMSPlugins *pPlugins;
IWMSPlugin *pPlugin;
IDispatch *pDispatch;
IWMSACLCheckAdmin *pACLCheckAdmin;
IWMSAccessControlList *pAccessCtrlList;
HRESULT hr;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.

CLSCTX_ALL,

(void **)&pServer);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to an IWMSPlugins interface
// containing event handler plug-ins.
hr = pServer->get_EventHandlers(&pPlugins);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to the IWMSPlugin interface
// of the plug-in to be configured.
varIndex = "WMS Publishing Points ACL Authorization";
hr = pPlugins->get_Item(varIndex, &pPlugin);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to the custom interface
// of the plug-in.
hr = pPlugin->get_CustomInterface(&pDispatch);
if (FAILED(hr)) goto EXIT;
// Query the specific administration interface
// for the plug-in.
hr = pDispatch->QueryInterface(IID_IWMSACLCheckAdmin,
(void **)&pACLCheckAdmin);
if (FAILED(hr)) goto EXIT;
// Retrieve a pointer to the list of access control entries
// and retrieve the number of entries it contains.
hr = pACLCheckAdmin->get_AccessControlList(&pAccessCtrlList);
if (FAILED(hr)) goto EXIT;
hr = pAccessCtrlList->get_length(&lCount);
if (FAILED(hr)) goto EXIT;
EXIT:
// TODO: Release temporary COM objects and uninitialize COM.
