Well, congratulations :)
Although I don't have any purpose for it, I'm quite interested in how it works.
Mind explaining a bit ? :D

Thanks

I think this explains a lot :

Code: [Select]
  char *origin = "/documents/hidden/";
  char *hidden = "/hidden/";

That's a cool program! It'll be neat to try it out once Ndless is finished up and released!

It works on Ndless 2 and 3 as it. no need to recompile it for Ndless 2.

Ok, sorry for double posting, but it seems that it doesn't work as expected on ndless 2.

So I removed show_dialog_box() from the code to make a non-gui version for ndless 2
http://levak.free.fr/ftp/nspire/HideManager/src/hide_nogui.tns

For upcomming ndless 3, I'm developping a password manager, but I have a problem : each time the program enter in a loop, glitches apear on the screen ... I would like to keep the screen as it to fake an error but asking a password in background.
Any idea ?

Most likely the glitching is because its switching color mode on you nspire.
Try to add set the color mode depending on the model, and it should be fine.
(Hackspire contains the info you need)

It could also be that Extended will fix this, but for now I guess doing it manually is the best :)

Interesting. So this is the TI-Nspire incarnation of MirageOS's hide function?

Compatibility of show_dialog_box() has been broken by TI with OS 3.x. Make sure to build Ndless 2 programs with the Ndless 2 SDK.

The screen will be cleared on program startup on CX in the next update to avoid this (the documents screen cannot be displayed in grayscale).
