Indeed you'd definitely have to use Blockchain.info for simplicity of calling a page & if you can't afford setting up a 512mb ram vps server with php +BDK+ Bitcoin running on it(which flash could query through php requests that way) although you do get the benefits of "controlling your money" when blockchain.info can potentially "defraud" you either by spoofing data or stealing private keys. I'm not attacking blockchain.info just stating that if your intention is to use bitcoin for some purposes such as "controlling your money" then that’s the wrong way to integrate your flash project into a device like Bitcoin.
I'd also like to note I'll be selling example scripts(which are complex and informative in comparison to the free complementary scripts) and for being down for so long I decided to have every function come with a "complementary" example script. The first free script up is the first example "generate an address". Here you go mates cheers! http://bitcoindevkit.com/examples/example1.php
*This gives me ideas of making an BDKas3
Your RPC server is down, or you moved your PHP script.
Edit: It's definitely your RPC server.
Thanks Bitcoin 0.8.1 went up today and its probably still loading I still need to link the BDK library to the Bitcoin RPC auth credentials too. In fact double thanks for reminding me its probubly finished syncing by now.
