Any idea is appreciated thanks ...

I have a flex component with 2 states - "" (ie no name / default) and "Transactional" - and a bunch of transitions to move from one state to the other.

I'm trying to accurately determine how many seconds of a video (NetStream) have been loaded so I can scrub/seek correctly. First I tried doing duration*(ns.bytesLoaded/ns.bytesTotal) but this is inaccurate by maybe 15%, ie if that calculation says 20 seconds is loaded and I scrub to 20 seconds ns.time will tell me it can't go past 17 se...

When I choose to load a second module (and unload the first) I again load a class MyBackground (from the second module). However, when I step into the constructor for MyBackgro...

I'm playing with Modules and they work as advertised: the module swf's ares built and deployed in the output directories automatically. My problem is that if I use descendants of mx:Module, the IDE does NOT do all this nice work for me. I've listed the module in the Flex Modules section of the project properties, but still nothing. I'm...

I am trying to use AlivePDF to save a chart into a .pdf file. However, when I try to save my chart, it ends up clipping half of the chart in the pdf so it isn't even fully visible. It seems that the screencapture that AlivePDF took to generate my pdf was too small. I am trying to get a chart from a sample to work with sample code for ...
