No, he wants to be able to make his own flash do that, i think. I answer is something to do with javascript . Beyond that i have no clue.

What you're trying to do in widnows requires editing a registry key somewhere - absoloutly no idea which registry key, but a spot of googling should uncover that for you.

Depending on how this is done, there are a selection of soloutions. If you mean people are submitting bogus scores to your high score table or such, that's an easier one to fix, just make each flash game provide a secret key passed over POST to the score script which will only accept scores containing that code. Or even better, encrypt the scores in the flash game and send as an encrypted string you can decrypt at the other end, so sending the score script large number won't affect it. The other possibility i can think of is people using a RAM hack to actually change the numbers in your flash game on their computer. To my knoweldge there is nothing you can do about this.

Is this possible? I've got a php script that handles encrypted data. When a file is requested for download, another script will decrypt the file, and then in theory serve it to the user, so they can download an unencrypted copy. Obviously i don't want these unencrypted versions hanging around, so is there a way of making each unencrypted copy not downloadable more than once? So it gets deleted right after the user has finished downloading it, and preferably is done in such a way as to prevent multiple people downloading it at once. Any ideas?
