A while ago Alex blogged about using WISP Lite (WISP stands for Windows Ink Services Platform) from managed code (see here). Previously accessing the Windows Mobile Ink API was only available from native code and some examples from Loke and the WM Team can be seen here and here.
Currently the Smart Device Framework has a the OpenNETCF.WindowsMobile.InkX control but uses the InkX Control API underneath the covers. Since the Windows Mobile Ink API is only supported on Windows Mobile 6.0 and InkX is compatible on Pocket PC 2003+ we decided to release the OpenNETCF.WindowsMobile.Ink source code as a open source project to the community and name it ‘OpenNETCF Mobile Ink Library’. Eventually it may be included in the Smart Device Framework but at this point we have no plans to do so.
In the next few days I will be following up with some technical information on OpenNETCF Mobile Ink Library.
