Ok  Experts??????

Show me your Work On This Littel Thing

I Got some Demo Source From Gwena Site Thanks To Her

But Now Iam Wondering if we can come up with something

To Protect A Single File From Being Copied From It's Original location Say On Floppy Disk Based On The CRC Technolegy

What i mean is :

With CRC  I Can Get  For EXAMPLE

Test.Exe

CRC16 = 19439
CRC32 = 1462223268
CRCArc = 14969

This is The Reading for my TEST.EXE File.

Now Iam Trying to Get My File To Change these Readings
When Ever SomeOne Moves It From It's Original location  to a new location on Hdd Or to CD Or To another Floppy Disk Or To LAN Or What Ever. How It Will Modify It Self Based On Gwena Source.

Now I Tried To Get My File To Know When Its Been Copied Or Moved Or Cut And Pased and i will tell him to add Short String To It Self So it Will Change The Size and then the CRC Readings Will Be Changed  And The Program Will Not Work.

Any Body Have Any Idea Let's See It. Thanks All

You want a file hook, that fires before the file is touched? Then you have to write a vxd driver (or equivalent in NT based systems). Or use an existing vxd. *Very* hard stuff...
