Description

During this course you will extend your knowledge of the formula language used in Domino applications for both Notes and Web browser clients.

This course doesn't simply regurgitate the Help--it shows you how to do some really interesting and important things in Notes/Domino that just happen to use the formula language. It is not, therefore, a detailed compendium of formula language calls and syntax. Instead, this course focuses on the strategy of using @Functions and @Commands to solve the pivotal issues faced by Domino developers.

Course goals

This course will:

  • extend your knowledge of the formula language
  • build your understanding of data validation and error trapping
  • provide extensive programming and debugging experience to ensure mastery of key @Functions and @Commands
  • use @Functions to operate on multi-value variables and Fields
  • describe how to conditionally execute code based on document state and user identity
  • explain data inheritance and inter-document relationships
  • show how to use well-known locations to store configuration information
  • show how to interact with users with prompts and dialog boxes
  • use mail to send documents between databases.


Audience

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

  • thorough knowledge of the Domino Designer development environment, including Form and View design, as well as how to use properties boxes, and how to set the ACL
  • mastered the topics covered in Domino Designer 8: Basic Notes Applications.


Though not required, experience in any computer programming or application scripting language (including spreadsheet formulas) is helpful in understanding how to maximize the use of the formula language.

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 2-day course.


Course design

This lecture-lab course involves significant hands-on coding experience using the formula language. It only peripherally explores the principles of programming and does not attempt to cover every option of every function.
