You can use the Tablet object to determine the hardware capabilities of the tablet device. A Tablet PC may have more than one digitizer attached in addition to the built-in digitizer.
Tablet objects work closely with ink collector. An ink collector (InkCollector, InkOverlay, or InkPicture) can be set to one of two tablet-related modes:
The default mode is all tablets mode (set with the SetAllTabletsMode method of the InkCollector..::.SetAllTabletsMode, InkOverlay..::.SetAllTabletsMode, or InkPicture..::.SetAllTabletsMode). This mode integrates all tablet devices if multiple devices are attached to Tablet PC. Because all of the tablets are integrated, available cursors can be used on any of the tablet devices, and each tablet maps to the entire screen. This allows automatic updating of the windows.
