CancelUpdate Method (RDS)
Cancels any changes made to the current or new row of a Recordset object.
Beginning with Windows 8 and Windows Server 2012, RDS server components are no longer included in the Windows operating system (see Windows 8 and Windows Server 2012 Compatibility Cookbook for more detail). RDS client components will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Applications that use RDS should migrate to WCF Data Service.
The Cursor Service for OLE DB keeps both a copy of the original values and a cache of changes. When you call CancelUpdate, the cache of changes is reset to empty, and any bound controls are refreshed with the original data.
