Your French is improving!

French is my worst foreign language. Let's try without Google then you can laugh:
Je doit parler plus français!

Edit: The red letters were added after I checked my mistakes. I actually thought it was like that. If I practice, what I learned will come back to me.

That's just like my own Welsh (Cymraeg llenyddol)

[czardas]

I'm fairly good with pronunciation and can even say 'parapluie'. Not many Germans can pronounce the word 'squirrel'.

@czardas & @jchd: Ladies, aren't we getting a bit off-topic here?

@Belini: I fear your quest is completely futile. If it's on screen, it can be copied. Never heard of screen recording software?

I would have thought _Crypt_DecryptData() would suffice (I haven't used it, so I'm not sure). Unfortunately videos are likely to require too much RAM. I'm also not sure how you would then play the video(s) after that. I'm sure it's doable though. If it were just plain text, it would be easy.

really should spend a lot of memory because they are videos for 5 to 10 minutes!

In fact the final answer has been posted to the French forum, where the OP is duplicating his request.

They are not equal topics, here I want to know how to prevent copying and ln the French forum I asked how to know when the copy started!

I think knowing when the copy started will be the best alternative because then I can use Shutdown(1) and avoid copying the whole file!

In this case not because there are more than 8,000 videos and would have to play all the way to the end to copy!

If copying the unprotected file does not need to capture what is on the screen and does not touch it all to copy so I want to avoid direct copying of the decrypted file!

if I know when the file copy was started I can turn off the pc and avoid copying it!

Funny you should perceive this as an obstacle on an AutoIt forum (Automate anything!).

AFAIK: 1) GetDC() does not trigger any windows message, interrupt, or anything else you can reliably hook into, 2) you cannot possibly detect every possible screen recorder software available (or written on-the-fly) as running process; 3) Using Skype, TeamViewer, or plain RDP, you can set up a 1-to-1 screen duplicate to any other machine, and record from there.

It gives to automate yes but it would take a lot of time, my concern is just to avoid direct copy of the same file!

Is this working?

The GDI+ stuff around is just a code to run.

@UEZ _WinAPI_LockFile () can prevent copying but does not let the player play the video too and if I put the video to play before _WinAPI_LockFile () can not protect because the video is already playing!

I totally agree, espacially since 'screen recorder software' was the obvious answer I provided on the french forum
1 file for 8000 videos, does that mean that your program displays parts on demand depending on given parameters ?
Sooo easy to automate

To use a screen recorder would need to know when a file started and when it finished and also put the right name on each file captured or capture all and then go hacking, it would need to have a good knowledge to do and not everyone has!

I really need to know when a copy was started, how can I know when a file is being copied?

[jchd]

You can achieve that by hooking into CreateFile().

https://www.codeproject.com/articles/30537/windows-file-monitoring-system-using-windows-api-h

[Belini]

I'll see if I can track the creation of new files here, thanks for the tip!

[jchd]

Not only created but opened as well.

[Belini]

the file will be opened anyway because it will be used by the video player!

 

[jchd]

So ?

When a second thread/process will want to open it for itself, won't it invoke CreateFile()? Yes it will since that's the only way to access a file.

[Belini]

If I can tell when another file was created, it will solve my problem!
