Is there a way i could use this to accept my website members id and then load up only there saved games and could the save proc be edited to save files to my website storage instead on the computers.
The demo was meant to be just that, a demonstration. If you want to expand it, it's basically on you.
I second this. I was just about to mention it. I've seen it happen so many times where passwords are stored as raw text and someone gets ahold of them.
md5() would be easy to implement, however I'd recommend something like SHA256.
If you're planning on updating this, I know a good library you could use for SHA256. You'll be required to include a DLL though.
