    How can I build copy protection into my program


    I have written a program. Now I want to sell my application.
    However, I want to be able to limit how many times that program can be
    installed through the serial number process.

    For Example:

    If I sell a five station license, I want my users to be able
    to install that program only 5 times. Then the program should
    refuse to install even if they attempt to use the same serial number.
    Then if they want to install it to more than five stations,
    they will have to contact me for an additional serial number,
    or get a new copy.

    Is it possible to do this in VB? When I compile and make a distributable
    copy, I don't see anywhere in the installation program (Package and
    Deployment Wizard) that allows a person to assign a Serial number
    to their program.

    Can someone show me the code to do this, and tell me specifically how to

    do it, and where that code goes? Does anyone have any experience in
    writing code to protect their program. I haven't seen any discussions
    about this on the board. If you know how to do this, or something similar,
    please teach me how. Without having to purchase a separate piece of
    copy protection software, (which I know nothing about), what is the
    most simplest way to copy protect a program during install in vb.

    Thanks a bunch
    William
