  • Article

The IUpdate::CanRequireSource (opnum 11) method retrieves whether the installation of the update can require source media.

 HRESULT CanRequireSource(
   [out, retval] VARIANT_BOOL* retval
 );

retval: MUST be VARIANT_TRUE if the update can require source media or VARIANT_FALSE if the update never requires source media.

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].

The server SHOULD return the value of the CanRequireSource ADM element.
