Want to setup excel file-downloaded once to a computer & disable ability to copy it

  • Good Day
    I'm almost finished creating an app designed for computers. What is the best way to code it, so that the file requires a password to open the workbook. (in workbook open event?) if you can please provide the code, I'd appreciate it. I'm password protecting my macros, so that the code is not available to the purchaser. Whatever you suggest must not interfere with this.
    I also need to include code, to disable the ability to copy the program and distribute it to others. This app is going to be extremely cheap. (I'll be inserting ads (Google Adsense) for a bit of extra income). In saying this, it may take off pretty good. Is there a way to set it up on my website, so the customer can download it without using my bandwidth?
    I'm including my ThisWorkBook. Maybe you can advise me where to insert it to save me from plenty of trial & error...LOL




    Thanks so much...Jimmy

  • You can add a workbook password or use a userform to let the user enter a password.
    Preventing copying, etc is virtually impossible software such as DoneEx Compiler, currently $149.00. It also obfuscates the code.


    I guarantee that anyone with the right knowledge and/or software can crack it


    SpreadSheet1's Unviewable works pretty well

  • Thanks Roy, I'll figure out how to set up a workbook password.
    Yeah I know that there's always a way to crack codes, but I just want to minimize the piracy as much as I can (for the average 'Joe'). I looked at the link that you sent me and am considering it.
    BTW do you know of a way I can set the program up, so that when someone purchases it, I can give them access to download it (as opposed to me sending it and using copious amounts of my bandwidth)?..Not counting on it selling millions...but who knows. It's a great program. My wifes' heart specialist loves it and :lurking: goes a long way
    Thanks again for your great help
