    Remarks

    Normally, DicomObjects stores licenses internally, using a combination of registry locations and files, but on some machines this is not feasible due to excessive security restrictions on the account under which it is running. In these cases, a developer may choose to intercept the storage of the license via the StoreLicense event, and then to provide it on request via this event.

    Note that DeleteAllLicenses does not affect this mechanism, so it is the developer's responsiblity to clear any stored key if required.
