Web page within flash   (170 Views)
I've been looking around like a forensic scientist piecing together information for my latest project. Basically I need to display a particular webpage within my flash file... Now I know flash can display simple HTML, but nothing complex and nothing from an external source... BUT I know flash can also handle PHP - obviously. The page I need to load is a wordpress website, a combination of PHP codes and simple HTML snippets... but what I couldn't find was a way of inserting the snippets into a control box or movieclip on my page (actually run the PHP code to fetch HTML snippets) I hope it's possible!! (although it's seeming less and less likely the more I read up)
Shared object using a flash server   (176 Views)
At the moment I'm developing something in which I need to have a server of some sort store and send Shared Objects. When I was looking into it the API said that you would use something like a flash media server. Well the student price for that is about 1300$ so I can't do that. Is there a way for me to create a server in actionscript using socket connections (or something). To send and receive shared objects I haven't started on this yet I'm just looking ahead into what I'm going to need.
Editing flash application text content. Best way?   (245 Views)
, I'm creating a Flash presentation, and the user wants to be able to change the text on any screen from Flash itself. This was my original my idea (I don't have much experience in AS): 1 - Put all the text in a text file (XML or plain). 2 - Make AS read the text and fill in the text fields in the Flash presentation. 3 - When it's needed to change the text content, execute the Flash presentation with a parameter that will tell AS to show all the fields as INPUT. 4 - Save the new text in the text file via PHP. But I have been asked if it would be possible to avoid the use of a text file (and the server connection with PHP) and change the swf text content directly with AS. Is this possible I have been googling it but with no success. I have the idea that this wouldn't be possible but i don't know all the possibilites in the Flash environment.

redirect browser from flash amfphp   (218 Views)
, I am currently developing an application in flash. In this application user will be able to buy in-game currency using real life money. For this purpose we have some external actors. In our case, it is hipay. Now, once a user clicks on a particular button, as3 will use amfphp to call a php file that eventually will do this: header("Location: ".$url) ; Once this happens I get an error in my flash: Error: Request for resource at https://test-payment.hipay.com/index...mevarialbes--- by requestor from http://mydomain.com/game.swf denied due to lack of policy file permissions Connection to https://test-payment.hipay.com/index...mevarialbes--- halted not permitted from http://mydomain.com/game.swf *** Security Sandbo Violation *** Warning: failed to load policyfile from https://test-payment.hipay.com/crossdomain.xml Now, is this a problem on my side or hipay's side.

passing keystrokes from air browser to flash game   (207 Views)
Here's my situation - I am accessing some games that my company built using a AIR browser (allowing us to sell an installable product on a CD, but keeping the content online for ease of maintenance). I can get the games to load, but i cant get them to accept keystrokes, ie: we have a tetris-like game that isnt getting any of the arrow key inputs. I'm fairly certain this has something to do with a focus issue, but I have no idea how to fix it. Any suggestions would be welcome.
Can flash load in SWCs at runtime?   (170 Views)
Beginners Intro to SWC files SWCs are ZIP archives with two files in them: catalog.xml - Lists all classes contained in the SWC along with their dependencies.library.swf - Contains all the actual classes So theoretically... It should be possible to load in SWC files at run time and use the classes from them, right You may have to unzip it first and extract out the SWF, but this arduous process could be made easier with a few helper classes. In fact, having the "catalog.xml" there may also make it easier to identify which classes are contained within (which means you don't need to guess or assume which classes are in it). Has anyone tried this yet or know of anyone else who has I searched Google for a bit, but most results actually were actually mislabeled, and loading the SWC in at compile time. I found nothing relevant, so asking here is much easier.
