  Hi Noam

  To retrieve any attribute of a license key such as the expiry date, you must do the following:

   

  1. Call DefineProduct with your product details

  2. Call ValidateLicense or ValidateLicenseEx with the license key you created.

  3. Call GetStatus and confirm that the license is valid

  4. Then, if the license is valid, you can access any attribute of the license such as ExpiryDate, Duration, etc.

  The first 3 steps described above are already performed for you in the LicenseValidator class that you can generated from the Protect Your Application Wizard.

  You essentially create an instance of the LicenseValidator class, then you call ValidateLicenseAtStartup. If this is successful, you have taken care of steps 1, 2 and 3 above.

  You will also find several useful properties in the LicenseValidator class such as IsEvaluation, EvaluationExpired, EvaluationRemainingDays.

   

  Hope this helps.

  thanks  the problem is 

  i create a key  with API  using CreateActivationKeyWithExpiryDate 

  then the function  ValidateLicenseEx always return invalid 

  if i create a local key it doesnt help me because then it doesn't exist in the server  

  do i have a get status  with api  ? 

  i tried to check  with  IsLicenseKeyValid - got valid key  

  the getstatus  alwyas return = 8 

   

  what am i doing wrong ?

  Hi Noam

   

  1. Are you calling DefineProduct before calling ValidateLicenseEx?

  2. Are you using the LicenseValidator class?

   

  Regards

  This Is the 3 function 

   

  lic.DefineProduct(1, "test", 1, 1, "TestDemo", "{24EAA3C1-3DD7-40E0-AEA3-D20AA17A6005}");

   

              lic.IsLicenseKeyValid(urlweb,key, out errorMsg);

  Hi Noam

  The proper sequence is:

  -DefineProduct

  -ValidateLicenseEx

  - GetStatus

  - IsLicenseKeyValid
