	* 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

	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

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

	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.

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

	missing 'using's.
	
2002-04-28  Rodrigo Moya <[email protected]>
	
	* System.Data/DataTableRelationCollection.cs: use 'new' keyword
	for correctly hiding parent class' members.

	* System.Data/ForeignKeyConstraint.cs
	* System.Data/UniqueConstraint.cs: added more stubs
	
	* System.Data/DataTableRelationCollection.cs: added back to cvs

	DataTable/DataSet.  DataTableRelationCollection was changed
	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.

	(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.
	(CopyTo): don't create the temporary array, it's not needed.

	* System.Data.build: excluded newly added file from build.

2002-04-27  Rodrigo Moya <[email protected]>

	* System.Data/DataTable.cs: modified - temporarily commented
	DataSet and DataView references - trying to compile a SqlDataReader,

	SqlDataAdapter, DataSet, and DataView will come later once we can get
	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
	failure to connect
