Most Notes application developers are familiar with the rich text field (RTF) — a powerful compound data type that allows you to add anything from text to embedded objects to Notes applications. While LotusScript classes and methods for working with RTFs offer some limited functionality for these fields, to manipulate the contents of an RTF — to change fonts, for example — you need to use one of the Notes APIs. In this article, you’ll find out how you can call HiTest C API functions from LotusScript to manipulate your RTFs. This method requires no C or C++ programming. And you can apply the same basic game plan illustrated in this article to the Notes C or C++ APIs as well. A companion example Notes database is available from THE VIEW’s home page; it includes all the function declarations, data types, and example code discussed in the article.
