Trial.dll Return Codes

[HadleyHope]

I cannot find a full list of return codes, what I want to check is the difference between a expired trial and the user cancelling the trial dialog.

0 = Licensed
2 = Valid Trial

I seem to be getting a return code of 5 if the dialog was cancelled, but not sure if that means that 4 means the trial has expired.

I have checked:
http://www.advancedinstaller.com/user-g ... using.html
http://www.advancedinstaller.com/user-g ... perty.html
http://www.advancedinstaller.com/user-g ... rties.html

None of which detail what codes 3, 4 and 5 mean (and whether there are any other codes above 5).


Thanks

Hi,

The codes that the "Trial.dll's" functions return are as follows:

• 0 - valid license
  2 - valid trial
  4 - invalid license
  5 - no license
  8 - trial expired
  16 - invalid configuration, something unexpected/wrong happened

I'm afraid that we do not have a return code for the scenario when the user cancels the trial dialog. However, can you please tell us why do you need this, what is your scenario, so we can see if there is any workaround for it or if we can make an improvement?

Best regards,

In a similar manner to the example project I am calling

Code: Select all

InitTrialReturn

to kick of the licensing check and then examining the result.

If the trial nag dialog is displayed the user can press the cancel button (or close the dialog) without doing anything (as well as pressing cancel on the registration dialog).

In the sample code:

Code: Select all

        uint ret = InitTrialReturn(kLibraryKey, process.MainWindowHandle);

        if (ret >= 4)
        {
            MessageBox.Show("Invalid mode to run");
            // disable the application 
            // Process.GetCurrentProcess().Kill();
        }

A value of 4 or greater is treated as an invalid mode to run, but if the trial period has not expired and the user has just cancelled the dialog (rather than click continue trial) the application should still run.

Just noticed that if the user does cancel or close the dialog the license details have not been read, so none of the properties have not been set.

We have changed our code for a return value of 5 to display a message stating the user must either opt to continue the trial or register.

Hi,

We will make an improvement in a future version of Advanced Installer so that the application will still run if the user canceled the trial dialog. Thank you for your suggestion.

Best regards,
