What interfaces does TADODataset.Recordset.Datasource support?
>From the msdn literature it looks like it should be an IRowset (as defined
in oledb.pas) however
Rowset := ADODataset1.Recordset.DataSource as IRowset;
where Rowset is an IRowset returns an Interface not supported error.
In fact iterating through all the GUIDs in OLEDB:
for i := Low(GuidArr) to High(GuidArr) do
begin
if Supports(AdoDataset1.Recordset.Datasource, GuidArr[i], Quack) then
ShowMessage(GUIDToString(GuidArr[i]));
end;
where Quack is IUnknown
suggests that it doesn't support any of them.
Any ideas where i'm going wrong?
Thanks
