How can I prevent the end user from printing the screen or saving it to a *.jpg file ?

Thank you,
Joe

Hi, Shift-Print is a standard windows function which saves the screen to the clipboard. What's the problem? I provide a button for the users to save the applications window to the clipboard in oder to send it for questions or documentation of an error. Of course, you could block the Shift-Print key with a hidden button ... but I don't understand what good that should be for?

Hi Joe,

Which product? I presume WebDev?

If so, do you mean you want to stop the user from right-clicking on one of your WebDev web pages and doing the actions you describe? If so, you'll probably have to resort to JavaScript - if you "Google", you'll find your answer. As for integrating it into your WebDev site, I'll have to defer to someone more knowledgeable...

Need to disable the enduser from printing screens or text on windev. This is a job that contains very confidential data.

Hi,

Hmm, interesting one... You would have to stop them from using all kinds of methods?! The first that springs to mind would be the Snipping tool supplied with Windows for example.

Hi Joe, if I wanted to take the data from a screen, a simple cell phone will suffice to do the job ...

Hi Joe

if the data is that sensitive, then I really hope that there is a GLOBAL security policy and that the system itself is secure, and that users are not allowed to come with any electronic devices near the computers and that....

and to prevent print screens and such, there are specialized security tools working at the SYSTEM level (that should NOT be part of your program)... By example : https://www.vera.com/blog/how-to-prevent-screenshots-with-vera/

Best regards

You can use the ToClipboard function to clear the clipboard content in one timer thar runs every 1 ms.

This only prevents from using the clipboard with things like Shift-Print, whithout something at system level you can't be sure and the user can always use one camera or mobile to get one image of the screen.

It is a very secure site metal detectors, no electronic devices, etc. Have been clients for a number of years. New management wants more security hence eliminating print screen. I will try Paulo's suggestion ....

Thank you all for the input,

Joe
