Using Bookmarks

Bookmarks allow consumers to quickly refer to rows in a rowset. They are:

• Used by methods in IRowsetLocate and IRowsetScroll.
  
  
• Valid only during the lifetime of a rowset.

See the OLE DB Programmer’s Reference for more information about bookmarks and the rowset properties that concern bookmarks.

CBookmark Class

The CBookmark class is declared in Bookmark.h and is implemented in Bookmark.cpp. It facilitates the use of bookmarks by handling the necessary conversion between bookmarks and VARIANTs. It also handles both fixed-length and variable-length bookmarks to provide additional convenience to the developer.
