Download XLTLI - Type Lib Utilities
This download provides about 20 VBA utility functions for working with the TypeLib Information object library, which is used to read type libraries. TypeLib Info is the "engine" behind the VBA Object Browser, and this library gives you programmatic access to type libraries, allowing you to determine the various arguments for methods, the symbolic names of constants, the methods of an object and so on. Complete documentation is in the VBA code of this workbook. This code is for advanced VBA programmers, not novices. An advanced version of XLTLI is available for commercial customers.
