As soon as you put these code snippets into a plug-in, you will have the following functionality:

• Objects within a CODESYS project than can hold arbitrary text (Simple Text object)
• An entry below "Project :: Add Object" for our Simple Text object, with a corresponding dialog (available top-level, and below applications)
• A text editor with which this object can be edited.
• Find / Replace functionality.

Please read through the code snippets, they are fairly commented. The Object Manager Concepts will be a good companion documentation for a better understanding.

To get the code running, you will need the following Automation Platform references:

• Interface component: ApplicationObject
• Interface component: Core
• GAC component: Utilities (no matter which version)
