PutClassWmi function

  • Artikkeli

Creates a new class or updates an existing one.

Note

This API is for internal use only. It's not intended for use from developer code.

Syntax

HRESULT PutClassWmi (
   [in] IWbemClassObject*    pObject,
   [in] long                 lFlags,
   [in] IWbemContext*        pCtx,
   [out] IWbemCallResult**   ppCallResult
);

Parameters

pObject
[in] A pointer to a valid class definition. It must be correctly initialized with all the required property values.

lFlags
[in] A combination of flags that affect the behavior of this function. The following values are defined in the WbemCli.h header file, or you can define them as constants in your code:

Constant Value Description
WBEM_FLAG_USE_AMENDED_QUALIFIERS 0x20000 If set, WMI does not store any qualifiers with the amended flavor.
If not set, it is assumed that this object is not localized, and all qualifiers are stored with this instance.
WBEM_FLAG_CREATE_OR_UPDATE 0 Create the class if it does not exist, or overwrite it if it exists already.
WBEM_FLAG_UPDATE_ONLY 1 Update the class. The class must exist for the call to be successful.
WBEM_FLAG_CREATE_ONLY 2 Create the class. The call fails if the class already exists.
WBEM_FLAG_RETURN_IMMEDIATELY 0x10 The flag causes a semisynchronous call.
WBEM_FLAG_OWNER_UPDATE 0x10000 Push providers must specify this flag when calling PutClassWmi to indicate that this class has changed.
WBEM_FLAG_UPDATE_COMPATIBLE 0 Allows a class to be updated if there are no derived classes and no instances of that class. It also allows updates in all cases if the change is just to unimportant qualifiers, such as the Description qualifier. If the class has instances or changes are to important qualifiers, the update fails.
WBEM_FLAG_UPDATE_SAFE_MODE 0x20 Allows updates of classes even if there are child classes as long as the change does not cause any conflicts with child classes. For example, this flag allows a new property to be added to the base class that was not previously mentioned in any of the child classes. If the class has instances, the update fails.
WBEM_FLAG_UPDATE_FORCE_MODE 0x40 forces updates of classes when conflicting child classes exist. For example, this flag forces an update if a class qualifier is defined in a child class, and the base class tries to add the same qualifier which conflicts with the existing one. In force mode, tis conflict is resolved by deleting the conflicting qualifier in the child class.

pCtx
[in] Typically, this value is null. Otherwise, it is a pointer to an IWbemContext instance that can be used by the provider that is providing the requested classes.

ppCallResult
[out] If null, this parameter is unused. If lFlags contains WBEM_FLAG_RETURN_IMMEDIATELY, the function returns immediately with WBEM_S_NO_ERROR. The ppCallResult parameter receives a pointer to a new IWbemCallResult object.

Return value

The following values returned by this function are defined in the WbemCli.h header file, or you can define them as constants in your code:

Constant Value Description
WBEM_E_ACCESS_DENIED 0x80041003 The user does not have permission to create or modify classes.
WBEM_E_FAILED 0x80041001 An unspecified error has occurred.
WBEM_E_INVALID_CLASS 0x80041010 The specified class is not valid. Typically, this indicates that pObject specifies an instance object.
WBEM_E_INVALID_PARAMETER 0x80041008 A parameter is not valid.
WBEM_E_INVALID OPERATION 0x80041016 The specified class name is not valid.
WBEM_E_CLASS_HAS_CHILDREN 0x80041025 An attempt was made to make a change that would invalidate a subclass.
WBEM_E_ALREADY_EXISTS 0x80041019 The WBEM_FLAG_CREATE_ONLY flag was specified, but the class already exists.
WBEM_E_NOT_FOUND 0x80041002 WBEM_FLAG_UPDATE_ONLY was specified in lFlags, and the class was not found.
WBEM_E_INCOMPLETE_CLASS 0x80041020 The required properties for classes have not all been set.
WBEM_E_OUT_OF_MEMORY 0x80041006 Not enough memory is available to complete the operation.
WBEM_E_SHUTTING_DOWN 0x80041033 WMI was probably stopped and restarting. Call ConnectServerWmi again.
WBEM_E_TRANSPORT_FAILURE 0x80041015 The remote procedure call (RPC) link between the current process and WMI has failed.
WBEM_S_NO_ERROR 0 The function call was successful.

Remarks

This function wraps a call to the IWbemServices::PutClass method.

The user may not create classes with names that begin or end with an underscore character.

If the function call fails, you can obtain additional error information by calling the GetErrorInfo function.
