I have a project I am working on that stores encrypted jpg images on a CD. What I am wanting to do is to write a program that will detect if a file of the extension .jpg is launched from the CDrom, then test to see if it is encrypted by the program and if it is it will prompt for a password to decrypt by. This means I need to encapsulate the normal windows data flow and trigger my decrypt program to launch when such a file is opened from any application (example: Paint Shop Pro) so that after decrypting, the outputted data will still go to the program (example: Paint Shop Pro) that requested it.
My problem is how to go about encapsulate the windows data flow. I'm not into Win API much yet so if someone could point me in the direction of a tutorial or Win API functions that I should study to help encapsulate the windows data flow I would appreciate it.
Many thanks for your time.
