Parts

Prototype (C/C++)
HRESULT PercentComplete(SQLDMO_LPCSTR Message, long Percent);
备注
With SQL Distributed Management Objects (SQL-DMO), use the SQLBackup, SQLRestore, and SQLVerify methods to start a backup or restore operation.
By default, SQL-DMO raises the PercentComplete event as each tenth of a backup or restore operation completes (when the percent of the operation completed is 10, 20, 30, and so on). Use the PercentCompleteNotification property of the Backup and Restore objects to change default behavior.
For the Replication object, the PercentComplete event is reserved for future use.
