    <p>Actionscript doesn't support multithreading, which I think is what you are really asking about here.</p> <p>While the functionality isn't inherent in actionscript (or Flex) you could set up a mock system using events and timers.</p> <p>I'm a little unclear on your exact question, so I'll give two answers:</p> <p><strong>1) You want to process a file every few seconds to act on any changes.</strong></p> <p>In this case all you need to do is set up a timer to check the file periodically:</p> <pre><code>var fileTimer:Timer = new Timer(5000); fileTimer.addEventListener(TimerEvent.TIMER, checkFile); ... private function checkFile(event:TimerEvent):void { // read the file and do whatever you need to do. } </code></pre> <p><strong>2) You want to parse a very large file but don't want the application to hang whilst doing it.</strong></p> <p>If you want to process the file in the background, while keeping the main application responsive then I would probably create a function that would parse several lines of the file and then send an event and return. Listen for the event and start a timer that would wait a few milliseconds before calling the function again to parse the next set of lines. </p> <p>This would break up the parsing of a large file with enough down time to keep the rest of your app running smoothly. You'd have to play with the timer interval and number of lines to parse at once to strike a good balance of responsiveness and the time needed to parse the file.</p> <p>Hope that makes sense!</p>

    1. COFlash Player will not render while ActionScript is running. validateNow() will force a Flex component to draw, but it does not actually render to the screen until all the ActionScript in a frame is finished running.

    2. COYou are absolutely correct, I've removed the erroneous code from my answer so that nobody attempts to use it.

    3. COA much better way is splitting up the parsing routine into recursive method calls, which would be called using callLater

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
