Hello Sir,




I have tried your code sample in a small application and it
worked fine. I would like you to check the return values of all LEADTOOLS
functions in your code and tell me if any of them return other than SUCCESS
(1), in order to pinpoint the problem. Also please let me know how the
encryption fails? I got a file that only opens If I give it one of the 2 passwords. I will be waiting for your feedback.


Kind regards,

Hello Sir,

Please find the attached project that produces a PDF which
causes Acrobat to ask the user to insert a password when trying to open it. I
have used the code you provided me with in your previous email. If you could
please test this project on your machine and let me know if the problem
occurred again.


Note: To be able to run the project, you need to uncomment the "L_UnlockSupport" code lines and type your lock keys there.




Kind regards,
