					Programming Languages for Domino Designer R5: LotusScript – 4 Days

Description

During this course you will thoroughly explore most of the Domino Object Model classes accessible to
LotusScript™. The primary emphasis of the course is not on LotusScript itself, but rather on how to use
basic LotusScript language elements to operate on the Domino object classes, including databases, views,
documents, fields, and ACL settings.

This course is not a beginning programming class or a mere overview presentation of the LotusScript
implementation in Domino and the Notes Client. You will spend a good portion of the course coding in
LotusScript and debugging code that will have immediate application beyond the term of the course.

Course goals

This course will:

        build a fundamental knowledge of LotusScript and how it is used to instantiate and execute
         Domino Object Model classes
        show appropriate use LotusScript to meet application goals
        provide extensive programming and debugging experience to ensure mastery of LotusScript
         techniques and Domino Object Model classes
        understand the relationship between LotusScript and Notes data types
        build a practical understanding of data validation and error trapping.

Audience

This course is designed for Domino Programmers. It assumes that you have:

        at least six months Domino application development experience
        thorough knowledge of the Domino Designer 5 development environment, including form, view,
         and agent design, as well as how to use properties boxes and set the ACL
        mastered the topics covered in Basic Applications for Domino Designer.

The course does not review any aspects of the non-LotusScript specific development environment.

Though not required, experience in any event-driven or structured programming language is helpful in
understanding how to maximize the use of LotusScript. If you have used LotusScript in other Lotus
applications or have built applications using Microsoft® Visual Basic™, you won't find this course
repetitive as it focuses mostly on the Domino Object Model.

Course design

The core of this course is hands-on coding experience using LotusScript. It only peripherally explores the
principles of programming and does not attempt to cover every option of every object class.

The course takes a task-oriented approach, during which you will create programs that are extremely
portable across applications and easy to move from buttons to fields to agents.

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.
