Description

LotusScript is a BASIC derivative that uses many of the same statements and function names, so most developers will find it easy to understand and use without too much relearning.
While this course teaches the basics of LotusScript, its primary emphasis is not on the language itself, but rather on how to use it to operate on Notes database, view, document, field, and ACL objects. With this knowledge, you will be able to develop powerful custom applications and extend the standard templates such as Mail or Discussion.

Course goals

This course will teach you how to:

  • use fundamental LotusScript language elements as you program and debug applications using Domino Designer
  • use LotusScript in various Notes events to operate on objects in the Domino Object Model
  • configure client, server, database, and document security mechanisms to allow LotusScript to operate
  • reconcile LotusScript and Notes data types and validate user input
  • design error handling routines to gracefully recover from runtime errors
  • operate on new and existing documents as well as on collections of documents
  • use messaging to send email, documents, and newsletters
  • operate on the database ACL and develop an alternative user interface so users can more easily administer database security
  • interact with users with both the primitive LotusScript and sophisticated Notes dialog boxes
  • use Profile documents to store application and user-specific configuration settings
  • develop custom procedures and classes and use Script Libraries to store and share commonly used procedures across design elements and applications
  • develop server-based Agents that use LotusScript and Notes objects to process documents
  • debug Agents using the Remote LotusScript Debugger, report errors to a log file, profile Agent performance, and work with your server administrator to develop application probes to monitor ongoing Agent performance
  • operate on file system based text files
  • generate MIME content that can be used to send formatted emails with intact HTML
  • parse XML files to extract element data and attributes
  • run procedures stored in Windows, Notes, and other product DLLs
  • instantiate objects from other products such as Office applications, Windows Script Host, and Windows Management Instrumentation via COM to use their properties and methods.


Audience

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.


Duration

This course is sold as a 4-day course, but it is unlikely that you can finish all the topics in four days. To finish in four days, it is recommended that you defer the last few topics for self-study. Many training centers allocate five days to cover this material.


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.
