CRegistryValue::CRegistryValue
|
|
|
|
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

CRegistryValue::CreateObject
|
|
|
|
Functionality:
|
|
|
|
Create WMI objects (Sce_RegistryValue). 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.

Functionality:

Put an instance as instructed by WMI. Since this class implements Sce_RegistryValue,

information to be saved in our store.

Virtual:

Yes.

Arguments:

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

Since GetProperty will return a success code (WBEM_S_RESET_TO_DEFAULT) when the

to test for the result of retrieving a property.
