NameDescription
System_CAPS_pubmethodRenewal(ILease^)

Requests a sponsoring client to renew the lease for the specified object.

An object must implement the ISponsor interface if it needs to request a lease renewal for a particular object. An object that implements the ISponsor interface can become a sponsor by registering itself with the lease manager. The ISponsor interface is used by the lifetime service to call back to the sponsor.

      lastRenewal = DateTime::Now;
