Can I set a period of time when I deploy a DLL?

Can I set a specific lifetime when deploying a DLL?

 

Or can I set up additional licenses for C language programs?

 

If possible, please explain what you need to do.

 

Thanks a good weekend

Expected this question as well. 

 

Implemented a scenario with below details:

 

  • During deployment , create a file and it should be in encrypted format.
  • If file is not found, you should deny to start toolkit code.
  • During each toolkit code run, set variable in encrypted file with current date and time. (You should fix this date time format irrespective of system date time format)
  • Before each new run, check and validate that current date and time should not be previous date and time saved into encrypted file.

It's possible. We have achieved the same.

 

Below should be done in user_initialize() :

  • Get current date from system using c++ functions. Compare the same with your designated valid date and compare both the dates.
  • If current date is not falling within your case, do return message to user about expiry date and return -1 for user_initialize().

It is a very good offer!
But the system time can be changeable

The above conditions are not particularly attractive if you change the system time.

Is there any other way?
For example, can I see that the system time has changed?
