How to trigger wisptis.exe to pick up new reg data from "HKLM\\SOFTWARE\\Microsoft\\Wisp\\Pen\\Digimon"

• Hi,

  I wrote some code to add tablet PC device and monitor device path to the following reg key

  "HKLM\\SOFTWARE\\Microsoft\\Wisp\\Pen\\Digimon".  

  I think this is exactly what the Tablet PC Settings > Display > setup... does to map tablet pc device to display.

  Restarting the TabletInputService seems making wistpis to pick up new data most of the time.  However, occasionally the user's wisptis process doesn't pick up the new data even after the restart of TabletInputService.  Is there any api to make wisptis to pick up the new reg data?

  Thanks,

  The only supported way to do this is via the control panel. There is no API to associate a digitizer with a specific monitor.

  Mucking with undocumented registry keys is not supported. While it may work in some situations it is not guaranteed to do what you want and may change without notice. This is not something you would want to do in production code.

  This is nice to use an api instead of user manually mapping digitzer with a monitor especially if the system has a lot of tabletpc devices and monitors.

  Anyway, thanks for your reply.
