WinForms RichEditControl API

This example demonstrates how to use RichEditControl API to programmatically manage rich text documents.
The application includes the RichEditControl (at the top) used to display and edit the code and another RichEditControl (at the bottom) which shows the result of code execution.
You can modify the code and watch the result. The code is executed two seconds after it is modified. If an error occurs during compilation or execution, the code window background color turns to pink.
