Course Modules

Module 1 - Streamlining Code with Procedures
A procedure (or sub-program) is a collection of instructions grouped together to perform a specific task. This module explains the need for procedures in LotusScript and describes how to define and use procedures in your Notes applications.
  • Understand the need for procedures in Notes applications and the advantages of using them
  • Be able to identify the types of procedures in LotusScript
  • Learn how to divide a program into procedures
  • Recognize a subroutine and its components
  • Learn how to create and use a subroutine
  • Recognize a function and its components
  • Learn how to create and use a function
  • Understand the concept of scope and be able to identify the scope of a variable or procedure
  • Understand the difference between passing arguments "by value" and "by reference"
  • List and demonstrate the variable values that a procedure can manipulate
  • Understand the issues that can arise when a procedure manipulates nonlocal variables
  • Learn how to locate, create, and use Script Libraries in your Notes and Domino applications
  • Learn how to call Java classes from LotusScript using the LS2J LotusScript Extension
  • Learn how to use the Evaluate Function to call @functions
  • Learn how to create custom classes to represent an object
Module 2 - Handling Run-Time Errors
If Notes encounters an error while running LotusScript code, it immediately stops execution and displays an error message to the user. It is good programming practice to anticipate where errors may occur and to provide a graceful way of handling them. This module describes how to intercept LotusScript run-time errors and handle them gracefully.
  • Understand the situations in which errors are most likely to occur
  • Learn how to use an If statement to test for an error condition
  • Learn where to find the list of LotusScript error codes
  • Learn how to intercept a run-time error
  • Learn how to develop a routine to handle errors and make it available to your scripts
  • Learn how to determine the line of LotusScript code that was executing when an error occurred
  • Learn how to retrieve a descriptive string that describes the error
  • Be able to provide multiple error-handler routines
  • Define and use your own error codes
  • Learn to direct Notes to use an error-handler routine in another procedure
  • Learn how to use the Remote Debugger tool to debug a LotusScript agent running on the server
  • Learn how Agent Profiling can be used to fine tune agents and web services
Module 3 - Creating and Maintaining a Log
One of the best ways to monitor agent activities and errors is to record them in a log. With LotusScript, you can create several different types of logs and you have complete control of what gets posted in them. This capability is extremely useful in documenting the changes an agent makes to Notes data and can be an excellent debugging tool.
  • Understand the need for agent logging in Notes and Domino applications
  • Understand the types of logs that LotusScript supports
  • Learn how to create and use a Notes log database
  • Learn how to create a log
  • Understand the kind of information that you can post in a log
  • Learn the steps required to post information to a log
  • Know how to track the number of additions that your code makes to a log
  • Be able to turn logging on and off
  • Learn how to determine the name of the current agent
  • Know how to determine who is the agent owner
  • Understand the importance of the agent owner
  • Learn how to trigger an agent to run immediately
  • Learn how to control when and where an agent runs
Module 4 - Working with ODBC Data Sources
Many organizations maintain at least some of their data in legacy systems that involve traditional relational databases. Most relational databases conform to an industry standard called the Open Database Connectivity (ODBC) standard. ODBC enables two diverse database systems to communicate with each other. Domino supports the ODBC standard and provides both formula language calls and LotusScript classes that you can use to access and update data in non-Notes databases.
  • Understand the basic structure of a standard relational database
  • Understand the requirements for using ODBC
  • Learn how to install ODBC drivers on your Windows system
  • Learn how to register the ODBC databases that you want to access via Notes
  • Understand what the LotusScript Data Object LSX module is and know how to load it
  • Be able to name the three object classes that comprise the LotusScript data object module
  • Know how to establish a connection to an ODBC data source
  • Know how to determine what the ODBC data source looks like
  • Be able to formulate an SQL query that specifies the data you want to access from the data source
  • Know how to provide interactive queries that let the user specify the data to access
  • Be able to retrieve the data from the ODBC data source into a result set
  • Be able to navigate the result set
  • Be able to copy data from the result set into Notes documents
  • Know how to write changes to existing data that are made in Notes back to the data source
  • Know how to add new information to a data source via Notes
  • Learn how to incorporate error handling capabilities into scripts that access non-Notes data
Module 5 - Using Lotus Connectors
DCRs, DECS and LEI use a technology called Lotus Connectors to interface with a back-end enterprise data source. Lotus Connectors are written using the native database's API to provide high performance. Lotus Connectors can be accessed via a set of APIs available through a LotusScript eXtension (LSX). This Lotus Connector LSX (LC LSX) allows the programmer to use high performance drivers to access any data source for which a connector is available such as DB2, Oracle, and Sybase. This module will teach you to use the LC LSX to read and write data using the Lotus Connectors technology.
  • Review the different enterprise data connection interfaces and understand how they use Lotus Connectors to interface with a back-end data source
  • Use the LC LSX to connect to a data source
  • Use the LC LSX to read data from a data source
  • Selectively retrieve data using the Selection keys
  • Update a record using either the Writeback or Keyed Update methods
  • Transfer data between two data sources using two Lotus Connectors
Module 6 - Advanced Techniques for Rich Text Fields
In this module you will learn advanced techniques for handling Rich Text fields. Objects such as doclinks, sections, and tables can be created and modified by simple coding. These techniques are specially useful for dynamic reporting and attractive presentations of the information.
  • Use the NotesRichTextNavigator class to navigate and work with rich text elements
  • Use the NotesRichTextRange class to work with a range of rich text
  • Use the NotesRichTextDocLink class to create, change, and remove doclinks and hotspots
  • Use the NotesRichTextSection class to create and remove sections
  • Use the NotesRichTextTable class to create, change and remove tables
  • Dynamically change the contents of a table cell
  • Use the NotesStream class to read and write data to and from the file system
  • Use the Notes MIME classes to create a formatted internet email via LotusScript
Module 7 - Additional Exam Topics
This module covers additional topics to help the student prepare for the Using LotusScript in IBM Lotus Domino 8 Applications (Exam 803) certification exam.
