AutoCompletion allows you to type the first few letters of a commonly used word (often technical or job specific), and tell TX Text Control to finish typing the word for you. This is often very useful when you have lengthy technical words. You can save a lot of valuable time using AutoCompletion, if you spend a lot of time of writing lengthy articles. Typically, AutoCompletion is implemented at the end user application level, due to the different requirements of every application. In this [sample application](https://github.com/TextControl/), you will learn how to implement AutoCompletion in a TX Text Control based word processing application. As usual, you can download the source code and do what ever you want with it - use it in your own applications, learn from it or integrate it into a new project. The source code does not have any copyright. --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
