Example 10: Enumerating the table and interview object model type library information
The Script Engine allows you to access the type library information for available UNICOM Intelligence objects. This example provides a simple method for using a standard Microsoft object to create a text file and an UNICOM Intelligence Data Model object in order to retrieve a type information list for the UNICOM Intelligence Reporter Tom Document Class and the UNICOM Intelligence IOM RunningInterviews Class.
The code writes the name and parameters for each function and property to a text file.
Code
This example is included with the UNICOM Intelligence Developer Documentation Library as the sample script
EnumerateTypeLibraryInfo.mrs. See
Sample mrScriptBasic files for more information.
' This script demonstrates how the mrScriptBasic type system can be used
' to enumerate the properties and methods of a Type Library
