Used to send complex information to other applications via AppleEvents.
In this example, the TextEdit application (which must be running for this example to work) is instructed to open two documents ("My Document" and "My Other Document") that are located in the folder with the default folder:
Dim list As AppleEventDescList
a = New AppleEvent("aevt", "odoc", "com.apple.textedit")
list = New AppleEventDescList
list.AppendFolderItem(GetFolderItem("My Other Document"))
a.DescListParam("----") = list
If Not a.Send Then
MsgBox("The AppleEvent could not be sent.")
