Interested in ink-enabling your application?

  Microsoft sent me a list of hands-on labs they have developed for those interested in developing for the Tablet PC and Ultra-Mobile PC platforms. Check out these labs and get started developing some ink-enabled applications today.

In addition to the below resources, check out this book on developing for the Tablet PC.

Updates to the Mobile PC Hands-On Labs

Get step-by-step information about how to build mobile and Tablet PC applications with these hands-on labs.

Adding Ink and Custom Rendering to Video in .NET Framework 3.0

Using Ink Analysis with Windows Presentation Foundation
This lab exposes you to ink analysis and the InkAnalysis API as they are used in the Windows Presentation Foundation. You add basic analysis to an ink-enabled form, improve ink analysis results by using analysis hints, use analysis hints to populate text boxes, use InkAnalysis APIs to analyze free-form ink, display the results of ink analysis on free-form ink and add a predetermined style to your application.

RealTimeStylus APIs
This lab familiarizes you with the Tablet PC RealTimeStylus (RTS) API. You create a pair of RTS plug-ins. The first plug-in is a packet filtering plug-in that demonstrates packet modification by constraining all (x,y) packet data within a rectangular area. The second plug-in is a simple custom dynamic renderer plug-in that renders stylus input by drawing a small circle around each (x,y) point. You then use your plug-ins in a sample application that is provided for you.
