mono/mcs/class/System.Data/ChangeLog

2002-05-18  Daniel Morgan <[email protected]>

	* System.Data.SqlClient/SqlCommand.cs: handle CommandTypes
	Text, TableDirect, and StoredProcedure
	
	* Test/PostgresTest.cs: changed call to version() 
	stored procedure to use the CommandType of StoredProcedure
	
	* Test/TestSqlDataReader.cs: test all the CommandTypes

2002-05-18  Daniel Morgan <[email protected]>

	* System.Data.build: took out all excluded
	files except the ones in the Test directory
	because all files compile now.  It does not
	mean they all work or have implementations
	though.
	
	* System.Data/DataRelationCollection.cs
	* System.Data/DataTableRelationCollection.cs
	* System.Data/InternalDataCollectionBase.cs
	* System.Data.Common/DbDataPermission.cs
	* System.Data.SqlClient/SqlInfoMessageEventArgs.cs
	* System.Data.SqlClient/SqlClientPermission.cs
	* System.Data.SqlClient/SqlClientPermissionAttribute.cs: changes
	to get all System.Data* files to compile.
	
	* System.Data.SqlClient/SqlCommand.cs: started coding
	to prevent SqlConnection and SqlCommand from doing
	anyting while fetching data using SqlDataReader.  Also,
	started coding to undo this prevention once the 
	SqlDataReader is closed.
	
	* System.Data.SqlClient/SqlConnection.cs: get database server
	version.  Started coding to prevent connection from 
	doing anything while fetching data and undo once the reader 
	is closed.  Include events SqlInfoMessage and StateChange.
	
	* System.Data.SqlClient/SqlDataReader.cs: start coding to
	prevent connection and command from doing anything while
	fetching data, and undo when closed.
	
	* Test/PostgresTest.cs: added test to get ServerVersion
	property from SqlConnection

2002-05-18  Tim Coleman <[email protected]>
	* System.Data/DataRow.cs: More implementation,
	as well as boundary checks and small semantic
	repairs

2002-05-18  Tim Coleman <[email protected]>
	* System.Data/DataRow.cs: Try to reduce memory
	usage by only creating the original and proposed
	arrays as required in BeginEdit, and then destroying
	proposed during EndEdit, and original during AcceptChanges.
	* System.Data.Common/DbDataAdapter.cs: Make the
	startRecord and maxRecords parameters work correctly.

2002-05-18  Tim Coleman <[email protected]>
	* System.Data/DataRow.cs: Move the null check in
	ItemArray set to above the Invalid Cast check, so
	that we don't get null reference exceptions.

2002-05-17  Daniel Morgan <[email protected]>

	* System.Data.SqlClient/PostgresLibrary.cs: handle
	data value from database being NULL
	
	* System.Data.SqlClient/SqlCommand.cs: for ExecuteReader, 
	allow multiple result sets.  Added new internal class
	SqlResult to pass result set data from SqlCommand
	to SqlDataReader.
	
	* System.Data.SqlClient/SqlDataReader.cs: allow
	multiple result sets.
	
	* System.Data.SqlClient/SqlConnection.cs: moved 
	things around.  Implement IDisposable.
	
	* Test/TestSqlDataReader.cs: test for execution
	of multiple result sets and display the results
	of these multiple results sets
	
	* Test/TestSqlDataAdapter.cs: tweaks

2002-05-17  Tim Coleman <[email protected]>
	* System.Data.Common/DbDataAdapter.cs:
		- More implementation of Fill methods
		- Get rid of isDirty flag, because we can just check
			if the table exists
		- Do *not* remove DataTables before Filling them
		- Implicitly open the connection before doing a Fill
			if it does not exist.
	* System.Data.SqlClient/SqlDataAdapter.cs:
		- Minor fixup
	* System.Data/DataTableCollection.cs:
		- Add DataSet to internal, undocumented constructor
		- When a table is created, set its DataSet property
		- Default table name for creation is "Table1" (see .NET)
		- Inherit the ArrayList list from InternalDataCollecitonBase
			and maintain a hashtable between table names and
			DataTables
	* System.Data/DataTable.cs:
		- Add internal dataSet field.  This is used by 
			DataTableCollection when the DataTable is constructed.
	* System.Data/DataSet.cs:
		- Pass a reference to the DataSet when constructing the
			DataTableCollection.

2002-05-16  Tim Coleman <[email protected]>
        * System.Data.Common/DbDataAdapter.cs:
                Use table.Rows.Add (itemArray) instead of
                table.Rows.Add (thisRow) to provide better
                abstraction.
        * System.Data/DataRowCollection.cs:
                Some implementation of this class.
        * System.Data/InternalDataCollectionBase.cs:
                Some implementation.  Most notably, this now
                has an enumerator so we can use foreach (DataRow row in table.Rows)
                in the test classes.
        * System.Data/DataTable.cs:
                Since DataRowCollection now accepts a DataTable in
                its internal constructor, we must pass one in.

2002-05-16  Daniel Morgan <[email protected]>

	* Test/TestSqlDataAdapter.cs: added new test 
	for SqlDataAdapter, DataSet, DataTableCollection, DataTable, 
	DataRowCollection, and DataRow.  It tests retrieving data
	based on a SQL SELECT query.  This test is based on Tim Coleman's
	test he sent to me.

2002-05-16  Tim Coleman <[email protected]>
	* System.Data.Common/DbDataAdapter.cs:
		Use table.Rows.Add (thisRow) instead of 
		table.ImportRow (thisRow)
	* System.Data/DataRowCollection.cs:
		Construct the ArrayList before using it

2002-05-16  Tim Coleman <[email protected]>
	* System.Data/DataTable.cs:
		Construct the DataRowCollection in the DataTable
		constructor.  Otherwise, it's a null reference.

2002-05-16  Tim Coleman <[email protected]>
	* System.Data.SqlClient/SqlDataReader.cs:
		Modify GetValues to use Array.Copy() to copy
		the results from fields to values, rather than
		an assignment, which results in loss of data.

2002-05-16  Tim Coleman <[email protected]>
	* System.Data/DataRow.cs:
		More implementation and documentation.  It should
		work more like expected, although there is no way
		to demonstrate this well yet.  DataTable requires
		more work.

2002-05-15  Tim Coleman <[email protected]>
        * System.Data/DataRow.cs:
	                Minor tweaks as I determine exactly how to
			                implement this class.


2002-05-14  Duncan Mak  <[email protected]>

	* System.Data/DataTable.cs (NewRow): Added missing paren to fix build.

2002-05-14  Tim Coleman
	* System.Data/DataRow.cs:
	* System.Data/DataRowBuilder.cs:
	* System.Data/DataTable.cs:
		More implementation of these classes.  DataRow
		can now (possibly) do some useful things.
		Still not sure what DataRowBuilder is all about,
		other than passing a DataTable in.

2002-05-14  Tim Coleman
	* System.Data/DataRowBuilder.cs:
		Add stubb for this internal class.

2002-05-13  Tim Coleman
	* System.Data.Common/DbDataAdapter.cs:
		The maxRecords check was not correct.

2002-05-13  Tim Coleman
	* System.Data/DataTableCollection.cs:
		Fix an issue when adding a DataTable and size == 0.
		Now explicitly checks if size > 0 before doing Array.Copy ()
	* System.Data.Common/DbDataAdapter.cs:
		Move closer to a working implementation.
		Make the IDbCommand fields protected so that they can
		be inherited.
	* System.Data.SqlClient/SqlDataAdapter.cs:
		This should inherit the IDbCommands instead of having its
		own.  An explicit cast is used to force conversion between
		IDbCommand and SqlCommand

2002-05-13  Tim Coleman
	* System.Data.Common/DataTableMappingCollection.cs:
		Some implementation to allow progress with DbDataAdapter

2002-05-13  Tim Coleman
	* System.Data.Common/DbDataAdapter.cs:
		Modify to not break compile.

2002-05-13  Tim Coleman
	* System.Data.build:
		include SqlDataAdapter, SqlRowUpdatedEventArgs,
		SqlRowUpdatingEventArgs, SqlRowUpdatedEventHandler,
		SqlRowUpdatingEventHandler in the build.

2002-05-13  Tim Coleman
	* System.Data.Common/DbDataAdapter.cs:
		More implementation.
	* System.Data.Common/DataAdapter.cs:
		Correction of some of the stubbing, as well as a
		little bit more implementation

2002-05-11  Tim Coleman
	* System.Data.SqlClient/SqlDataAdapter.cs:
	* System.Data.Common/DbDataAdapter.cs:
		Moved methods that weren't supposed to 
		be in SqlDataAdapter out.  They should be implemented
		in DbDataAdapter.
	

2002-05-11  Tim Coleman
        * System.Data.SqlClient/SqlDataAdapter.cs:
                some implementation of this class.  Note
                that none of the functionality has been
                tested yet, but I felt it should be checked
                in at this point as it compiles.
        * System.Data.SqlClient/SqlRowUpdatingEventArgs.cs:
        * System.Data.SqlClient/SqlRowUpdatedEventArgs.cs:
                Modified so that they will compile properly.
                Needed to include SqlDataAdapter in the build.

2002-05-11  Rodrigo Moya <[email protected]>

	* System.Data/DataTable.cs (Clear): implemented.
	(DataTable): removed repeated code in constructors, and call the
	basic constructor from the others.

	* System.Data/DataColumn.cs: some tweaks.

	* System.Data/DataRow.cs (RowState): implemented.
	(CancelEdit): set rowState property back to Unchanged.
	(RejectChanges): call CancelEdit.
	(Delete): set rowState to Deleted.

2002-05-11  Daniel Morgan <[email protected]>

	* System.Data.build: added copy of System.Data.dll to Test directory
	for easy testing.  Also, added clean for it too.
	
	* System.Data.SqlClient/PostgresLibrary.cs: changed setting of boolean
	from PostgreSQL data type to .NET type.
	
	* System.Data.SqlClient/SqlDataReader.cs: beginnings
	handling of a NULL value from the database
	
	* Test/PostgresTest.cs: added tests for NULL values retrieved
	from the database
	
	* Test/ReadPostgresData.cs
	* Test/TestExecuteScalar.cs
	* Test/TestSqlDataReader.cs
	* Test/TestSqlException.cs
	* Test/TestSqlIsolationLevel.cs: updated tests to use databas user
	"postgres".  These tests may eventually be removed since they
	are not flexible.

2002-05-10  Rodrigo Moya <[email protected]>

	* System.Data.build: removed reference to non-existant
	TestDataColumn.cs file.

	* System.Data/DataSet.cs: added some implementation.

2002-05-09  Daniel Morgan <[email protected]>

	* System.Data.SqlClient/PostgresLibrary.cs: got
	PostgreSQL data types time, date, timestamp (DateTime like)
	mapped to .NET System.DateTime working based 
	on ISO DateTime formatting "YYYY-MM-DD hh:mi:ss.ms"
	Also mapped pg type boolean to .net Boolean
	
	* SqlClient/SqlConnection.cs: run SQL command to set
	Date style to ISO
	
	* Test/PostgresTest.cs: added test for an UPDATE SQL command,
	added tests for aggregates min(), max(), sum(), count().  could
	not get avg() to work due to some formatting error; someone claimed
	that it was my locale settings.  added tests for SELECT of columns
	of type boolean, float, double, date, time, and timestamp.  They
	have not been fully tested, but its a start.

2002-05-09  Tim Coleman <[email protected]>
	* System.Data.SqlTypes/SqlDecimal.cs: Implementations of 
	addition, subtraction, and multiplication for the
	SqlDecimal type, as well as modification of some other
	operations.  More to come on this one.

2002-05-08  Rodrigo Moya <[email protected]>

	* Test/System.Data_test.build: excluded TestDataColumn, which
	should be replaced with a nunit test.

	* Test/TestDataColumn.cs: added basic test for DataColumn.cs.

2002-05-07  Tim Coleman <[email protected]>
	* SqlBinary.cs:
	* SqlBoolean.cs:
	* SqlByte.cs:
	* SqlDateTime.cs:
	* SqlDecimal.cs:
	* SqlDouble.cs:
	* SqlGuid.cs:
	* SqlInt16.cs:
	* SqlInt32.cs:
	* SqlInt64.cs:
	* SqlMoney.cs:
	* SqlSingle.cs:
	* SqlString.cs:
		Fix the broken build I made before.  Bad
		me.

2002-05-07  Tim Coleman <[email protected]>
	* SqlString.cs:
		Fix a symantic error I made in SqlString
		Equals where I copied and pasted wrongly

2002-05-07  Tim Coleman <[email protected]>
	* INullable.cs:
	* SqlBinary.cs:
	* SqlBoolean.cs:
	* SqlByte.cs:
	* SqlCompareOptions.cs:
	* SqlDateTime.cs:
	* SqlDecimal.cs:
	* SqlDouble.cs:
	* SqlGuid.cs:
	* SqlInt16.cs:
	* SqlInt32.cs:
	* SqlInt64.cs:
	* SqlMoney.cs:
	* SqlSingle.cs:
	* SqlString.cs:
		Implement CompareTo, Equals, and String conversions 
		for many types

2002-05-05  Daniel Morgan <[email protected]>

	* Test/PostgresTest.cs: modified to run completely.  There
	are many TODOs in System.Data, so not all data types are
	included in the SELECT SQL query.  Also, I made it to where
	it would connect 
	using "host=localhost;dbname=test;user=postgres"
	instead of my userid and password.  When more types are included,
	update this test.

2002-05-05  Daniel Morgan <[email protected]>

	* Test/PostgresTest.cs: added - ported
	libgda postgres-test.c originally by 
	Gonzalo Paniagua Javier <[email protected]>
	to C#.

2002-05-05  Tim Coleman <[email protected]>
	* System.Data.SqlTypes/SqlBinary.cs:
	* System.Data.SqlTypes/SqlBoolean.cs:
	* System.Data.SqlTypes/SqlByte.cs:
	* System.Data.SqlTypes/SqlDateTime.cs:
	* System.Data.SqlTypes/SqlDecimal.cs:
	* System.Data.SqlTypes/SqlDouble.cs:
	* System.Data.SqlTypes/SqlGuid.cs:
	* System.Data.SqlTypes/SqlInt16.cs:
	* System.Data.SqlTypes/SqlInt32.cs:
	* System.Data.SqlTypes/SqlInt64.cs:
	* System.Data.SqlTypes/SqlMoney.cs:
	* System.Data.SqlTypes/SqlSingle.cs:
	* System.Data.SqlTypes/SqlString.cs:
		More implementation, and code clean-up for consistency.
		Also, I had implemented many conversions as explicit
		that should have been implicit.  This should remove
		many of the red X's and green pluses from the 
		System.Data.SqlTypes namespace.

2002-05-05  Miguel de Icaza  <[email protected]>

	* System.Data/DataSet.cs: Remove [Serializable] attributes from
	methods, those only apply to structs or classes.

	Stub out ISerializable, ISupportInitialize, and IListSource methods 
	
	* System.Data/DataRowView.cs: Stub out interface methods for
	IEditableObject, ICustomTypeDescriptor and IDataErrorInfo

	* System.Data/DataView.cs: Comment out non-implemented
	interfaces. 

	* System.Data/DataViewSettingsCollection.cs: Type cast variables
	to the correct type to make it compile.

	* System.Data/DataViewSettings.cs: remove reference to
	non-existance type ApplyDefaultSort, it is a boolean.
	

2002-05-05  Tim Coleman <[email protected]>
        * System.Data.SqlTypes/SqlBinary.cs:
        * System.Data.SqlTypes/SqlBoolean.cs:
        * System.Data.SqlTypes/SqlByte.cs:
        * System.Data.SqlTypes/SqlDecimal.cs:
        * System.Data.SqlTypes/SqlDouble.cs:
        * System.Data.SqlTypes/SqlGuid.cs:
        * System.Data.SqlTypes/SqlInt16.cs:
        * System.Data.SqlTypes/SqlInt32.cs:
        * System.Data.SqlTypes/SqlInt64.cs:
        * System.Data.SqlTypes/SqlMoney.cs:
        * System.Data.SqlTypes/SqlSingle.cs:
        * System.Data.SqlTypes/SqlString.cs:
                Various fixes, including adding the SqlNullValueException
                when trying to retrieve the value of a null SqlType,
                and when casting values, a Null of type A converts to a
                Null of type B.

2002-05-04  Daniel Morgan <[email protected]>
	
	* System.Data.SqlClient/PostgresLibrary.cs
	* System.Data.SqlClient/SqlCommand.cs
	* System.Data.SqlClient/SqlConnection.cs
	* System.Data.SqlClient/SqlDataReader.cs
	oid should not be hard coded because they
	can change from one version of PostgreSQL
	to the next.  Use the typname's instead.
	The PostgreSQL type data retrieves
	at database connection time.  Any unimplemented
	types just default to string.  These were things
	suggested by Gonzalo.
	
	* Test/ReadPostgresData.cs - stuff
	* Test/TestSqlDataReader.cs - stuff
	
	* System.Data.SqlTypes/SqlInt32.cs - added a using

2002-05-03  Tim Coleman <[email protected]>
	* System.Data.build: Fix the build so that test depends on build

2002-05-03  Tim Coleman <[email protected]>
	* System.Data.SqlTypes/SqlByte.cs:
	* System.Data.SqlTypes/SqlDateTime.cs:
	* System.Data.SqlTypes/SqlDecimal.cs:
	* System.Data.SqlTypes/SqlDouble.cs:
	* System.Data.SqlTypes/SqlGuid.cs:
	* System.Data.SqlTypes/SqlInt16.cs:
	* System.Data.SqlTypes/SqlInt64.cs:
	* System.Data.SqlTypes/SqlMoney.cs:
	* System.Data.SqlTypes/SqlSingle.cs:
		These files were mysteriously excluded from the last
		patch I made and sent to Rodrigo
	* System.Data.build: include the System.Data.SqlTypes in the build

2002-05-03  Daniel Morgan <[email protected]>

	* System.Data.build: removed comments

	* System.Data.SqlClient/PostgresLibrary.cs: changed
	the hard-coded PostgreSQL oid type int's to using an
	enum.  Also, added PostgreSQL bpchar (character) type.
	
	* Test/TestSqlDataReader.cs: updated test
	to include new bpchar PostgreSQL type

2002-05-03  Rodrigo Moya <[email protected]>

	* System.Data.SqlTypes/SqlBinary.cs:
	* System.Data.SqlTypes/SqlBoolean.cs:
	* System.Data.SqlTypes/SqlInt32.cs:
	* System.Data.SqlTypes/SqlString.cs: more implementation, by
	Tim Coleman <[email protected]>.

2002-05-03  Daniel Morgan <[email protected]>

	* Test/TestExecuteScalar.cs: added test for 
	method ExecuteScalar in class SqlCommand.
	
	* System.Data/DataColumnCollection.cs - it should
	inherit properties from base InternalDataCollectionBase
	and use them instead of overriding them, such as, List.
	
	* System.Data/DataColumn.cs
	* System.Data/DataTable.cs: tweaks to retrieve
	meta data from the database
	
	* System.Data.SqlClient/PostgresLibrary.cs -
	added method OidToType to convert PostgreSQL oid type 
	to System.Type.  Renamed method OidTypeToSystem
	to ConvertPgTypeToSystem for converting the data value
	from a PostgreSQL type to a .NET System type.
	
	* System.Data.SqlClient/SqlCommand.cs: implemented
	method ExecuteReader which returns a SqlDataReader
	for a light forward only read only result set. 
	It works on types int4 ==> Int32 and 
	varchar ==> String.  Other types
	will come later.
	
	* System.Data.SqlClient/SqlConnection.cs: added comment
	
	* System.Data.SqlClient/SqlDataReader.cs: implemented
	class.  It works, but still lots to do.
	
	* Test/ReadPostgresData.cs: stuff
	
	* Test/TestSqlDataReader.cs: updated test for SqlDataReader
	to display meta data and the data
	
2002-05-03  Duncan Mak  <[email protected]>

	* TODO: Took out all the Exceptions. They should be all done now.

	* System.Data/ConstraintException.cs: 
	* System.Data/DBConcurrencyException.cs:
	* System.Data/DataException.cs: 
	* System.Data/DeletedRowInaccessibleException.cs: 
	* System.Data/DuplicateNameException.cs:

	* System.Data/StrongTypingException.cs:
	* System.Data/SyntaxErrorException.cs: 
	* System.Data/TypeDataSetGeneratorException.cs: 
	* System.Data/VersionNotFoundException.cs: Added to CVS.

	* System.Data.SqlTypes/SqlNullValueException.cs: 
	* System.Data.SqlTypes/SqlTruncateException.cs: 
	* System.Data.SqlTypes/SqlTypeException.cs: Added to CVS.

2002-05-02  Rodrigo Moya <[email protected]>

	* System.Data/DataViewSettingCollection.cs: implemented.

	* System.Data/DataRowView.cs: new stubs.

	* System.Data.SqlTypes/SqlByte.cs:
	* System.Data.SqlTypes/SqlDateTime.cs:
	* System.Data.SqlTypes/SqlDecimal.cs:
	* System.Data.SqlTypes/SqlDouble.cs:
	* System.Data.SqlTypes/SqlGuid.cs:
	* System.Data.SqlTypes/SqlInt16.cs:
	* System.Data.SqlTypes/SqlInt64.cs:
	* System.Data.SqlTypes/SqlMoney.cs:
	* System.Data.SqlTypes/SqlSingle.cs: new stubs, contributed
	by Tim Coleman <[email protected]>

	* System.Data.build: excluded newly-added files.

2002-05-02  Daniel Morgan <[email protected]>

	* System.Data.SqlClient/PostgresLibrary.cs: included new 
	internal class that will be a helper class in using
	PostgreSQL.  PostgresLibrary is used for the 
	pinvoke methods to the PostgreSQL Client
	native C library libpq while the class PostgresHelper 
	is used for	wrapper or helper methods.  It currently only
	has one static method OidTypeToSystem in converting
	PostgreSQL types to .NET System.<type>s, such as,
	a PostgreSQL int8 becomes a .NET System.Int64.
	Only a few types have been added, such as, int2,
	int4, int8, varchar, text, bool, and char.  Other types
	will come later.
	
	* System.Data.SqlClient/SqlCommand.cs: implemented
	method ExecuteScalar which allows us to do aggregate
	functions, such as, count, avg, min, max, and sum.  We
	also are able to retrieve the result, convert it to the .NET type
	as an object.  The user of the returned object must explicitly cast.
	
	* Test/ReadPostgresData.cs: updated sample
	to help us learn to retrieve data in System.Data.SqlClient
	classes

2002-05-01  Daniel Morgan <[email protected]>

	* System.Data.build: added /nowarn: nnnn arguments 
	so you will not get a ton of warnings.  The warnings
	being excluded are: 1595, 0067, 0109, 0169, and	0649

2002-05-01  Daniel Morgan <[email protected]>

	* System.Data.build: modified to exclude more 
	files from the build

2002-05-01  Rodrigo Moya <[email protected]>

	* System.Data.SqlClient/SqlClientPermission.cs: added missing
	'using's.

	* System.Data/MergeFailedEventArgs.cs: new class, contributed
	by John Dugaw <[email protected]>.

	* System.Data.build: excluded new files from build.

2002-04-29  Daniel Morgan <[email protected]>

	* Test/ReadPostgresData.cs: added - Uses the 
	PostgresLibrary to retrieve a recordset.
	This is not meant to be used in Production, but as a
	learning aid in coding 
	class System.Data.SqlClient.SqlDataReader.
	This sample does work.
	
	* Test/TestSqlDataReader.cs: added - used
	to test SqlDataReader (does not work yet)
	Forgot to add to ChangeLog on last commit.

2002-04-28  Rodrigo Moya <[email protected]>

	* System.Data/DataViewSetting.cs: new class.
	
2002-04-28  Rodrigo Moya <[email protected]>

	* System.Data/DataViewManager.cs: new class.
	
	* System.Data.SqlTypes/INullable.cs: properties for interfaces
	don't have implementation.

	* System.Data.SqlTypes/SqlInt32.cs:
	* System.Data.SqlTypes/SqlString.cs:
	* System.Data.SqlTypes/SqlBoolean.cs: removed destructor, since
	these are strctures.

	* System.Data.SqlClient/SqlClientPermissionAttribute.cs: added
	missing 'using's.

	to an internal class.
	
	* System.Data.build: modified - new files added
	also wanted to include files/classes in the build 
	so we can get a compilable forward read only result set.
	It compiles now using csc/nant with warnings, but this 
	is a start for adding functionality for the result set.  
	Classes associated with/and DataSet are still excluded.

	which returns a SqlDataReader

2002-04-28  Rodrigo Moya <[email protected]>

	* System.Data/DataTableCollection.cs: more implementation.
	(Count): added 'override' keyword, as pointer out by Martin.

	* System.Data.Common/DataColumnMappingCollection.cs (Add, AddRange):
	only call Array.Copy when there is really stuff to be copied.

	a forward read only result set working.
	
	* System.Data/IDataRecord.cs: modified - source code lines should
	not be > 80
	
	* System.Data/InternalDataCollectionBase.cs: modified - started 
	implementing this base class for collection of data rows,
	columns, tables, relations, and constraints
	
	* System.Data.SqlClient/SqlException.cs: modified -
	call base(message) so a unhandled exception displays
	the message of a SQL error instead of the 
	default SystemException message
	
	* Test/TestSqlException.cs: modified - 
	handle the rollback properly for a SqlException on a

	Also, got rid of compile warnings for hostaddr and port.

	* System.Data.SqlClient/SqlErrorCollection.cs: modified - got
