Re: [flexcoders] Re: Capturing and Saving an image in Flex (BitmapData)
You'll need some server-side code to accept the image upload and save it to
disk. It's pretty simple in PHP.
On the Flex side, you'll just need to use something like URLLoader or
HTTPService to POST the image to your upload form on the server.

Re: [flexcoders] help - code assist stopped working
Are you using FB as an Eclipse plugin? If so, you should be able to get the error log by going to Window->Show View->Other, then picking Error Log from the list. -Brian On Thu, Mar 4, 2010 at 11:55 AM, Chris Sheffield wrote: > > > I apologize.

Re: [flexcoders] VideoDisplay - video is playing, but without audio
One of our projects has suffered from a similar issue. We're streaming audio from Flash Media Server, and sometimes the audio will cut out - we still get cue points embedded in the audio, the NetStream object doesn't register any errors, and the rest of the app acts like the audio ends at the right time. We also have a recording aspect to our project, and when the audio cuts out, sometimes it will cut back in after we record something. We've really only noticed this problem when running the app on Windows 7 -- and it's more prevalent when the computer is connected via wireless. Have you noticed any similar patterns in your app? -Brian On Wed, Mar 3, 2010 at 10:30 PM, joyh2002 wrote: > I use VideoDisplay to play videos in my Flex app. The videos are hosted in > our local web server.
