This course is designed for Notes programmers well versed in using Domino Designer 8. It assumes that you have:

• extensive experience using Notes 8
• thorough knowledge of the Domino Designer 8 development environment, including Form and View design
• mastered the concepts covered in the Domino Designer 8: Basic Notes Applications course.

The course does not review any aspects of the non-LotusScript specific development environment such as how to design forms or views.

Though not required, experience in any event-driven or structured programming language is helpful in understanding LotusScript. If you have used LotusScript in other Lotus applications or have built applications using Microsoft® Visual Basic™, you will find that this course won't be repetitive as it focuses mostly on Notes objects.

This course is part of a series of Domino Designer 8 training courses. Follow these paths to master all aspects of developing applications using Domino Designer:



Domino Designer 8: Basic Notes Applications provides the base knowledge for this additional training:

Client Track

• Configure Domino to use DB2 as a database engine and build applications that access relational data, DB2 for Domino 8 Administrators and Developers.
• Specialize in programming Notes applications to respond to built-in user interface features, Domino Designer 8: Special Notes Features.
• Convert an application written for Notes clients to be used in browsers, Domino Designer 8: Basic Browser Applications.
• Provide data to cutting-edge Web applications, Domino Designer 8: Web Agents and Web Services.

Language Track. These languages apply to both Notes and browser clients:

• Learn sophisticated application techniques that fully exploit the formula language in Domino Designer 8: Formula Language.
• Develop sophisticated applications and Agents with LotusScript in Domino Designer 8: LotusScript.
• Add powerful client-side scripting to browser applications in Domino Designer 8: JavaScript.

Course design

This is a lecture/lab course in which you will closely examine demonstration code and create additional code. You will immediately apply the concepts and techniques as you work in your own project database.

This is not an introductory programming course. Its emphasis is on how to use LotusScript to manipulate Notes objects. All major concepts are reinforced with examples and exercises, during which you will code and debug LotusScript. From this experience you will have the necessary skills to build sophisticated applications.

All code fragments are labeled to make talking about them and reusing them in exercises easier. The intent in labeling them is also to help build a sense of modularity, purpose, and a way of "thinking" about LotusScript.
