	adds the "reset" bit in the Status flag field of packet header.
	Set socket option to keep alive, whereever supported and also, let
	the socket close along with the underlying stream.

	* Tds70.cs (Reset): Use the new ResetConnection property instead

	returned to the pool when they are closed. Fixes bug #443131.

2008-09-16  Veerapuram Varadhan  <vvaradhan@novell.com>

	Patch from Christian Hergert <christian.hergert@gmail.com>

2008-07-06  Gert Driesen  <drieseng@users.sourceforge.net>

	* TdsConnectionPool.cs: When pooled connection cannot be reset, remove
	it from pool and allow slot to be re-used for a newly established
	connection. Fixes part of bug #360157. When pool is full, and no

	* TdsDataColumnCollection.cs, Tds50.cs, Tds42.cs, Tds70.cs,
	Tds.cs: adjust for changes below.

	* TdsDataColumn.cs: use the named properties only in the 2.0
	profile. The reason is that Mono.Data.TdsClient.TdsDataReader
	needs to know if a property has been set or not. With 2.0 it is
	easy to implement using nullable types, with 1.x it would require
	using e.g. BitArray to control which field was set, and in
	addition extra code would be needed to check whether a field was
	set or not. Also, it would clutter the code with #ifdefs all over
	the map.

2008-06-30  Zoltan Varga  <vargaz@gmail.com>

	* TdsDataColumn.cs: Do not inherit from Hashtable, add always set properties
	as normal properties so code can access them without doing a hashtable lookup.

	TdsPacketSubType.Done. So I changed the behaviour to include this
	(without deeper knowledge of the TDS protocol). Patch from Jörg
	Rosenkranz <joergr@voelcker.com>.

	This is part of a fix to bug #40315.

	Patches from Igor Nosyryev <nosyryev@attbi.com>
	
	* TdsComm.cs: (GetString): GetString adds extra byte to a string
	at end. It suppose to be '\0', but '\0' is valid value in .NET
	string, so this byte must not be used.
 
	* Tds.cs (GetDecimalValue):Method reads extra byte if a DECIMAL
	field contains NULL. As a result server's response is parsed
	incorrectly and this method fires an exception.

2003-01-20  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* Tds70.cs:
	(FormatParameter): send input/output parameter names. This way we don't
	depend on the parameter position being different of the index in the
	parameter collection.

2002-12-10  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* Tds.cs:
	(Disconnect): close the stream and set connected to false.
	(NextResult): check if after DoneProc we have a ColumnMetadata + Row,
	which holds the values for the output parameters and read them.
	(LoadRow): add the values to outputParameters if DoneProc.
	When executing a stored procedure, we execute the procedure and then
	select the parameter values.

	* Tds70.cs:
	(BuildParameters): check Parameters.

	* TdsComm.cs: added Close () to close the stream.

	* TdsConnectionParameters.cs: initialize all the string to be empty.

	* Tds42.cs:

		Fixed GetString because it wasn't working properly
		with TDS 7.0.

        * Tds70.cs:
        * Tds80.cs:
                New classes added.  Functionality

                Remove some unnecessary code after
                the above split, and add in a whole

        * TdsComm.cs:

		in the Java implementation.
