The IDrivers Interface

interface IDrivers: IDispatch
{
  [propget, id(0x00000003), helpstring("List of drivers from 0 to Count-1")]
   HRESULT _stdcall Items([in] long i, [out, retval] BSTR * Value );

  [propget, id(0x00000001), helpstring("Drivers' Count")]
   HRESULT _stdcall Count([out, retval] long * Value );
}

The object implementing the IDrivers interface provides the complete list of installed available ODBC drivers in the system the object has been created in. A string it supplies is representing each driver - you can see all these strings on the Drivers table of ODBC Driver Manager.
