>In our application is an Editor (Richtext Control) which is used by the user to create Konfiguration files. I am wondering what would be the possibility to create something like IntelliSense, where the program detects if an object (or Aliasname) exists and lists the members to select from. If someone has thoughts or ideas, I would highly appreciate your Input.

We use it in our APP for customizing Code Hooks.
