Is it possbile to play a file from the memory without caching it on the HDD?

Hi all

I want to know something :

Is it possible to run and play a file from the memory without storing the file on the HardDisk Drive?

I mean for example : a Video file (Encrypted) I want to send it to the memory and then Decrypt it there.. and then the decrypted file will be placed on the memory without caching it on the HDD and will be played from there also without caching it..

So is it possible to play the file from the memory?

I know it is possible.. but can anybody give me some examples using any language like : Visual Basic.. C++.. ASM...

I prefer VB..

Please it is very important to do that..

Cheers..

I like this 64k intro

VB is crap - use w32asm or C.

Lightbulb Don't forget about swap file...

There is one more thing not to be forgotten though it's more important in real secure systems - swap file. Not saving data to file doesn't mean they won't be saved by operating system. Memory pages must be set as not swappable and it wasn't working well in windows 98, maybe it is on XP... Antoher solution is to encrypt swap file (easily done in Linux, not sure about windows) or to disable swapping (often not recommended).

Real, secure application will also wipe data from memory when they are no longer needed (by writing there many times some random garbage bytes)...
