Methods

Name Description
SetSite Sets the site that contains the rowset object.

Remarks

This class inherits from IObjectWithSite and overrides IObjectWithSite::SetSite. When a provider command or session object creates a rowset, it calls QueryInterface on the rowset object looking for IObjectWithSite and calls SetSite passing the rowset object's IUnkown interface as the site interface.

IRowsetCreatorImpl::SetSite

Sets the site that contains the rowset object. For more information, see IObjectWithSite::SetSite.

Syntax

STDMETHOD(SetSite )(IUnknown* pCreator);

Parameters

pCreator
[in] Pointer to the IUnknown interface pointer of the site managing the rowset object.

Return Value

A standard HRESULT.

Remarks

In addition, IRowsetCreatorImpl::SetSite enables the OLE DB DBPROPCANSCROLLBACKWARDS DBPROPCANFETCHBACKWARDS properties.
