Functionality:

|
This is the constructor. Pass along the parameters to the base class
|
|
|
|
Virtual:
|
|
|
|
No (you know that, constructor won't be virtual!)
|
|
|
|
Arguments:
|
|
|
|
pKeyChain - Pointer to the ISceKeyChain COM interface which is prepared
|
|
by the caller who constructs this instance.
|
|
|
|
pNamespace - Pointer to WMI namespace of our provider (COM interface).
|
|
Passed along by the caller. Must not be NULL.
|
|
|
|
pCtx - Pointer to WMI context object (COM interface). Passed along
|
|
by the caller. It's up to WMI whether this interface pointer is NULL or not.
|
|
|
|
Return Value:
|
|
|
|
None as any constructor

Notes:

if you create any local members, think about initialize them here

CAccountLockout::CreateObject
|
|
|
|
Functionality:
|
|
|
|
Create WMI objects (Sce_AccountLockoutPolicy). Depending on parameter atAction,
|
|
this creation may mean:
|
|
(a) Get a single instance (atAction == ACTIONTYPE_GET)
|
|
(b) Get several instances satisfying some criteria (atAction == ACTIONTYPE_QUERY)
|
|
(c) Delete an instance (atAction == ACTIONTYPE_DELETE)
|
|
|
|
Virtual:
|
|
|
|
Yes.
|
|
|
|
Arguments:
|
|
|
|
pHandler - COM interface pointer for notifying WMI for creation result.
|
|
atAction - Get single instance ACTIONTYPE_GET
|
|
Get several instances ACTIONTYPE_QUERY
|
|
Delete a single instance ACTIONTYPE_DELETE
|
|
|
|
Return Value:
|
|
|
|
Success: it must return success code (use SUCCEEDED to test). It is
|
|
not guaranteed to return WBEM_NO_ERROR. The returned objects are indicated to WMI,
|
|
not directly passed back via parameters.
|
|
|
|
Failure: Various errors may occurs. Except WBEM_E_NOT_FOUND, any such error should indicate
|
|
the failure of getting the wanted instance. If WBEM_E_NOT_FOUND is returned in querying
|
|
situations, this may not be an error depending on caller's intention.

CAccountLockout::PutInst
|
|
|
|
Functionality:
|
|
|
|
Put an instance as instructed by WMI. Since this class implements Sce_AccountLockoutPolicy,

which is persistence oriented, this will cause the Sce_AccountLockoutPolicy object's property
|
|
information to be saved in our store.

Yes.

pInst - COM interface pointer to the WMI class (Sce_AccountLockoutPolicy) object.
|
|
|
|
pHandler - COM interface pointer for notifying WMI of any events.
|
|
|
|
pCtx - COM interface pointer. This interface is just something we pass around.
|
|
WMI may mandate it (not now) in the future. But we never construct

|
such an interface and so, we just pass around for various WMI API's

Success: it must return success code (use SUCCEEDED to test). It is

Failure: Various errors may occurs. Any such error should indicate the failure of persisting

Notes:
|
|
Since GetProperty will return a success code (WBEM_S_RESET_TO_DEFAULT) when the
|
|
requested property is not present, don't simply use SUCCEEDED or FAILED macros
|
|
to test for the result of retrieving a property.
