			/// <para>The <b>GetClassID</b> method retrieves the class identifier (CLSID) for an object, used in later operations to load object-specific code into the caller's context. <h3><a id="Notes_to_Callers"></a><a id="notes_to_callers"></a><a id="NOTES_TO_CALLERS"></a>Notes to Callers</h3> A container application might call this method to retrieve the original CLSID of an object that it is treating as a different class. Such a call would be necessary if a user performed an editing operation that required the object to be saved. If the container were to save it using the treat-as CLSID, the original application would no longer be able to edit the object. Typically, in this case, the container calls the <a href="https://docs.microsoft.com/windows/desktop/api/ole2/nf-ole2-olesave">OleSave</a> helper function, which performs all the necessary steps. For this reason, most container applications have no need to call this method directly. The exception would be a container that provides an object handler for certain objects. In particular, a container application should not get an object's CLSID and then use it to retrieve class specific information from the registry. Instead, the container should use <a href="https://docs.microsoft.com/windows/desktop/api/oleidl/nn-oleidl-ioleobject">IOleObject</a> and <a href="https://docs.microsoft.com/windows/desktop/api/objidl/nn-objidl-idataobject">IDataObject</a> interfaces to retrieve such class-specific information directly from the object. <h3><a id="Notes_to_Implementers"></a><a id="notes_to_implementers"></a><a id="NOTES_TO_IMPLEMENTERS"></a>Notes to Implementers</h3> Typically, implementations of this method simply supply a constant CLSID for an object. If, however, the object's <b><a href="https://docs.microsoft.com/windows/desktop/com/treatas">TreatAs</a></b> registry key has been set by an application that supports emulation (and so is treating the object as one of a different class), a call to <b>GetClassID</b> must supply the CLSID specified in the <b><a href="https://docs.microsoft.com/windows/desktop/com/treatas">TreatAs</a></b> key. For more information on emulation, see <a href="https://docs.microsoft.com/windows/desktop/api/objbase/nf-objbase-cotreatasclass">CoTreatAsClass</a>. When an object is in the running state, the default handler calls an implementation of <b>GetClassID</b> that delegates the call to the implementation in the object. When the object is not running, the default handler instead calls the <a href="https://docs.microsoft.com/windows/desktop/api/coml2api/nf-coml2api-readclassstg">ReadClassStg</a> function to read the CLSID that is saved in the object's storage. If you are writing a custom object handler for your object, you might want to simply delegate this method to the default handler implementation (see <a href="https://docs.microsoft.com/windows/desktop/api/ole2/nf-ole2-olecreatedefaulthandler">OleCreateDefaultHandler</a>).</para>
