3.2.4.2 IAutomaticUpdatesResults::LastInstallationSuccessDate (Opnum 9)

  • Article

The IAutomaticUpdatesResults::LastInstallationSuccessDate (opnum 9) method retrieves the date-time of the most recent successful installation done by the automatic update agent.

 HRESULT LastInstallationSuccessDate(
   [out, retval] VARIANT* retval
 );

retval: If the date-time for the last successful update search is not known, the vt field MUST be set to VT_EMPTY. Otherwise, the vt member MUST be set to VT_DATE, and the date-time of the last successful update installation MUST be stored in the date field.

Return Values: The method MUST return information in an HRESULT data structure. The severity bit in the structure identifies the following conditions:

  • If the severity bit is set to 0, the method completed successfully.

  • If the severity bit is set to 1, the method failed and encountered a fatal error.

Exceptions Thrown: No exceptions are thrown beyond those thrown by the underlying RPC protocol [MS-RPCE].

This method SHOULD return a VARIANT containing the value of the LastInstallationSuccessDate ADM element.
