Routine Description:
Name:
CSecurityDatabase::CSecurityDatabase
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

Routine Description:
Name:
CSecurityDatabase::~CSecurityDatabase
Functionality:
Destructor. Necessary as good C++ discipline since we have virtual functions.

Yes.

none as any destructor
Return Value:
None as any destructor
Notes:
if you create any local members, think about whether
there is any need for a non-trivial destructor

Routine Description:
Name:
CSecurityDatabase::CreateObject
Functionality:
Create WMI objects (Sce_Database). 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)
Virtual:
Yes.
Arguments:
pHandler - COM interface pointer for notifying WMI for creation result.
atAction - Get single instance ACTIONTYPE_GET
Get several instances ACTIONTYPE_QUERY
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.
Notes:
for Sce_Database, we don't support delete!
