I've already done that, but everything is a characterized also not clear.
It lacks a few other examples.
Although it is already a good start.

I also study the reference

thank you

You should really read the developer guide - many samples and much help ;-)

thanks for good help.

It is fun with Quick PDF to work, but I need more time to understand anything.
Working only one week so ...

It's nice that you help so much :-)

Hi Luet,

the functionality offered by Debenu isn't completely straight.
LoadFromFile should be the first...
LastErrorCode should be the second (to check code 404 = password error).
GetAnalysisInfo (for detecting a mainpassword) should be the last.

Loading a pdf with QuickPDF always works, even if you don't know the main password (an empty string is enough). So having a file with an unknown main password you can load it and use GetAnalyseInfo to check for a main password.
If there's a user password even LoadFromFile (and all similar functions) fails. So there's no possibility to check if a user password is set even if GetAnalysisInfo offers these option ;-)
In this case (existing user password) you can only use LastErrorCode and check for result 404.

thank for answer.
is there no other possibility?
There's a CheckPassword method ...
Or do I have previously also run only LoadFromFile?

Thank you for a few lines of code

I have found it simplest and quickest to open the file and see if it fails with "invalid password" (404).  If you use DAopenfilereadonly it should be very quick because it does not have to read the whole file.  You can close it if it is successful and then re-open the file with LoadFromFile if you prefer this.]]> Tue, 16 Aug 2016 14:32:15 +0000 http://www.quickpdf.org/forum/passwort-check_topic3369_post13385.html#13385 <![CDATA[Passwort Check : How can I check whether a password...]]> http://www.quickpdf.org/forum/passwort-check_topic3369_post13384.html#13384 Author: luet

How can I check whether a password must be specified before opening a PDF file?
To open a protected PDF file so I need a Paswort how do I know that before opening QPdf.LoadFromFile?

Thank you for a few lines of code
