The IComponentData::QueryDataObject method returns a data object that can be used to retrieve the context information for the specified cookie.

Syntax

HRESULT QueryDataObject(
  [in]  MMC_COOKIE        cookie,
  [in]  DATA_OBJECT_TYPES type,
  [out] LPDATAOBJECT      *ppDataObject
);

[in] cookie

A value that specifies the unique identifier for which the data object is required.

[in] type

A value that specifies the data object as one of the following:

Data object for the scope pane.

Data object for the result pane.

Data object for the Snap-In Manager context.

Data object has an invalid type.

These constants are members of the DATA_OBJECT_TYPES enumeration.
