Return Code
S_OK
The method succeeded.
E_FAIL
A provider-specific error occurred.
DB_E_BADCHAPTER
hChapter was invalid.
DB_E_BADROWHANDLE
hRow was invalid.
DB_E_CANCELED
The operation was canceled by a client during notification. The current row is set to DB_NULL_ROW with a position flag indicating DBPOSITION_NOROW.
E_INVALIDARG
hRow was set to DB_NULL_ROW and dwPositionFlags indicated DBPOSITION_OK.
dwPositionFlags indicated DBPOSITION_OK, but hRow was an invalid value.
dwPositionFlags indicated DBPOSITION_NOROW, DBPOSITION_BOF, or DBPOSITION_EOF, and hRow was not set to DB_NULL_ROW.
E_UNEXPECTED
SetRowPosition was called without first calling ClearRowPosition.
There is no current rowset.
ITransaction::Commit or ITransaction::Abort was called and the object is in a zombie state.
Comments
ClearRowPosition must be called prior to the first and any subsequent SetRowPosition calls.
SetRowPosition fires the following notification phases with either DBREASON_ROWPOSITION_CHANGED or DBREASON_ROWPOSITION_CHAPTERCHANGED:
The RowPostion object maintains a reference count on the both the hRow and the hChapter by respectively calling AddRefRows for the hRow and AddRefChapter for the hChapter when SetRowPosition is called.
