问题 What is RSL and what is the use of RSL? Have any sample example , Please shared me,. Thanks, Ravi 回答1: Runtime shared libraries RSLs are just SWF files whose code is used as a shared library between different application SWF files. There are two kinds of RSLs, signed and unsigned.

问题 I've found it's often useful to special case the first item in a drop-down menu (ie, an instance of Menu). For example, if I want to pick a color from the list provided by a web service: <mx:PopUpMenuButton id="colorSelelector" dataProvider="{colorsService.lastResult}" /> I might also want a special-case, which is "enter a new color", allowing the user to enter the RGB values for a new color which isn't in the list. For example: var newColor = { label: "Enter a new color", rgb: null }; Then

问题 Is it possible to serialize a hierarchy of objects in Flex, send the binary data to a URL for storage/retrieval on/from a server, and deserialize the data to restore the objects' original state? I know it's possible to convert the objects into an XML format (haven't tried it yet), but I'm hoping to avoid parsing XML and rebuilding the objects manually. It would be nice to have functionality which can serialize/deserialize objects to a simple binary format (I did something similar in the past
