On November 9, Adobe announced in a blog post[1] that it had decided to cease efforts to develop browser plugins for mobile devices to play Flash, indicating that HTML5 was "the best solution for creating and deploying content in the browser across mobile platforms."

Implementing the Microsoft Rich Edit Control

What we needed to do was implement spell checking in the rich edit fields in our application (see Figures 1 and 2).

As a result, the messages and functions it supports are completely differen... (more)
