IDirectManipulationViewport::SetTag method (directmanipulation.h)
Sets a viewport tag.
Syntax
HRESULT SetTag(
[in, optional] IUnknown *object,
[in] UINT32 id
);
Parameters
[in, optional] object
The object portion of the tag.
[in] id
The ID portion of the tag.
Return value

Remarks
A tag is a pairing of an integer ID with a Component Object Model (COM) object. It can be used by an app to identify the viewport.
The object parameter is optional, so that the method can set just an ID.

IUnknown* pUnk = ...;
UINT32 id = ...;
HRESULT hr = pRegion->SetTag(pUnk, id);
