One-handed Pocket PC Applications

Mark has posted the final version of his MSDN article on designing for stylus-free usage on Windows Mobile. This covers both what you get for free in .NETCF v2.0 for navigating around forms with the d-pad and also what you can do to make some of the other intrinsic controls behave. Mark’s sample code includes wrappers around these “badly behaved” controls such as the DateTimePicker.

Want to know more about OpenNETCF.Security.Cryptography?

As Sam points out, the OpenNETCF.Security.Cryptography library was donated to the OpenNETCF codebase by fellow MVP Casey Chesnut. So a good source of information about how the library is built is Casey’s original article on the subject.

The library is designed in such a way that it follows the object model of the System.Security.Cryptography namespace in the full framework. A background on the Cryptographic services in .NET can be found here in the MSDN library.

These include “Why does calling AcceptChanges followed by DataAdaptor.Update do nothing to the database” and “why doesn’t calling Remove on a row doesn’t remove the row from the database”.
