You might be able to get around screen captures etc by painting directly to the visible screen.

 

Then you are left with the problem of deciding when the info is re-painted……..

 

For a one-time paint, you can call GetDC(0) which gives you a device context to paint on with API calls.

 

Not tested, and I don’t know if it will do what you want, but it’s worth a look.

Subject: [DUG] Odd-ball question

 

Is there a way to display confidential information on a screen in such a way that it can be seen but cannot be copied - eg via copy and paste.

 

For instance putting text in labels does not allow normal select and copy, but one can still do a printscreen and capture the screen as an image.

 

The only way I have thought of is to put text in a pop-up hint, as these normally disappear when a key such as printscreen is pressed.  It is not however that easy to put many lines of text in a hint.

 

Any suggestions?
