This example creates a small string dictionary and uses it to automatically translate some English words for colors to their hexadecimal representations by connecting to a BeforeKeyPress event. Replace the code in Connect.cs file with the example code below. Run this add-in and open a text document in the Visual Studio integrated development environment (IDE). In the text document, type "red", "green" or "blue" to see the event-capturing method translate the text to "#ff0000", "#00cc00", and "#0000ff", respectively. For more information about how to run the automation examples, see How to: Compile and Run the Automation Object Model Code Examples.
