Excerpt of article text...
In the last issue I explained, in general terms, how folderitems work, and how to use them to read and write text and binary files. But folderitems can do a lot more. There are built-in methods for reading pictures, styled text, movies, sounds, and more. Today we're going to explore those features.
Built-in Folderitem Methods
Working with a folderitem's built-in methods for reading in pictures, styled text, movies, and sounds is easy: in most cases you simply read the item into a variable you've created for the purpose. For example, if f is a folderitem that points to a movie file and qt is designated a movie object, the following would read in the movie and place it inside the qt property:
qt = f.readAsMovie
Of course you also need some simple supporting code. Here's an example from today's demo project:
dim f as folderItem
dim qt as movie
f = getFolderItem("catsumo.mpeg")
if f <> nil then qt = f.openAsMovie
if qt <> nil then
moviePlayer1.border = true
