GetActivityEnumerator method

Retrieves a collection of Accelerators that can execute given the specified input and output context.

Internet Explorer 8



HRESULT retVal = object.GetActivityEnumerator(pInput, pOutput, ppEnumActivity);


pInput [in]

Type: IOpenServiceActivityInput

An IOpenServiceActivityInput interface that specifies a content type, or NULL to enumerate all entries in the category.

pOutput [in]

Type: IOpenServiceActivityOutputContext

An IOpenServiceActivityOutputContext interface that specifies the output context, or NULL to specify no output context.

ppEnumActivity [out]

Type: IEnumOpenServiceActivity

The IEnumOpenServiceActivity interface that contains the collection.

Return value


If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.


If specified, the pInput and pOutput parameters are used to filter which Accelerators appear in the collection. If they are NULL, the type used to initialize the IEnumOpenServiceActivityCategory enumerator will be used instead. See IOpenServiceActivityManager::GetCategoryEnumerator.

An Accelerator may support multiple content types. If the content type of the pInput parameter is different than the type used to initialize the category enumerator, then only Accelerators that support both types are included in the results.
