        add support for MySQL in Mono.Data.MySql
        and OleDb support in System.Data.OleDb.  However,
        the OleDb support is commented right now.
        When the program starts up, a shorter help menu should
        display the most important commands: help and quit

2002-05-28  Rodrigo Moya <rodrigo@ximian.com>

        * System.Data.build: exclude System.Data.OleDb files.

2002-05-27  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data.SqlClient/SqlCommand.cs: typo
        should be CommandBehavior.KeyInfo
        
        * Test/SqlSharpCli.cs: refactored and added a few more
        features.

2002-05-27  Tim Coleman <tim@timcoleman.com>
        * list: update to compile properly (add missing
        files and switch path delimiter from '\' to '/').

2002-05-26  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data/DataRow.cs
        * System.Data.Common/DbDataAdapter.cs: fix to
        get Test/TestSqlDataAdapter.cs to work again
        
        * Test/TestSqlDataAdapter.cs: removed comment
        about SqlDataReader:NextResult() not being implemented; it
        bas been implemented

2002-05-26  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data/DataRow.cs: modified
        support setting of DBNull.Value
        using the Item indexer this[DataColumn]
        
        * System.Data.SqlClient/SqlCommand.cs: modified
        tweaks to show TODO's for other CommandBehavior.
        Set AllowDBNull column to true for IsKey row 
        in schema DataTable.
        
        * System.Data.SqlClient/SqlConnection.cs: modified
        if transaction is in progress when a Close() is called,
        do a transaction Rollback.

2002-05-26  Daniel Morgan <danmorg@sc.rr.com>

        * Test/SqlSharpCli.cs: added file
        My new toy.  SQL# is a command-line tool to enter
        SQL     commands and queries using Mono System.Data.
        It also serves as a test for Mono System.Data.
        
        * System.Data.SqlClient/SqlCommand.cs: modified
        - ExecuteNonQuery(), ExecuteScalar(), and ExecuteReader()
        should handle the results from SQL Commands and Queries.
        - Internal class SqlResult should not create schema Table
        for the result from a SQL Command.  Also, set the RecordsRetrieved
        property for SqlDataReader.
        - Closing the SqlDataReader should Close() the SqlConnection for
        a CommandBehavior.CloseConnection.
        - Set defaults for SqlResult
        
        * System.Data.SqlClient/SqlConnection.cs: modified - 
        when SqlDataReader is Close()
        should Close() the SqlConnection for
        a CommandBehavior.CloseConnection.  Changed internal Property
        from OpenReader get/set to IsReaderOpen get and created
        internal methods OpenReader()/CloseReader() for SqlCommand to call.
        SqlConnection needs to be prevented from doing while SqlDataReader
        is being used.
        
        * System.Data.SqlClient/SqlDataReader.cs: modified -
        call SqlCommand's OpenReader() internal method.  get
        RecordsRetrieved from SqlResult.  set/reset default
        values for SqlDataReader.
        
        * Test/PostgresTest.cs
        * Test/TestExecuteScalar.cs
        * Test/TestSqlDataReader.cs: modified
        for the Execute...() methods in SqlCommand
        to test SQL Queries and Commands
        
        * Test/System.Data_test.build: modified
        exclude new file Test/SqlSharpCli.cs from 
        test build
        
2002-05-24  Tim Coleman <tim@timcoleman.com>
        * System.Data.Common/DbDataAdapter.cs: remove IDbCommands, except
        for get accessors.  These should be implemented in derived classes.  See
        SqlDataAdapter for clues.
        * System.Data.SqlClient/SqlDataAdapter.cs: implement IDbDataAdapter
        * System.Data.Common/DataAdapter.cs:
        * System.Data.Common/DataTableMappingCollection.cs:
        * System.Data.Common/DataTableMapping.cs:
        * System.Data.Common/DataColumnMappingCollection.cs:
        * System.Data.Common/DataColumnMapping.cs:
        Properly (I hope!) implement all of the appropriate interfaces
        for these classes.  


2002-05-23  Tim Coleman <tim@timcoleman.com>
        * System.Data.SqlClient/SqlCommand.cs: include
        the BaseColumnName in the schema table.  Was missed before.
        * System.Data.Common/DbDataAdapter.cs: Use DataTable
        mappings so that the DataSet and DataTable are more closely tied.
        Get schema information from the DataTable using GetSchemaTable ()
        Various other little fixes
        * System.Data.Common/DataColumnMappingCollection.cs:
        * System.Data.Common/DataTableMapping.cs:
        * System.Data.Common/DataTableMappingCollection.cs: Some
        implementation, enough to be used by DbDataAdapter.

2002-05-23  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data.SqlClient/SqlCommand.cs: set
        the "ProviderType" to the PostgreSQL type oid
        
        * System.Data.SqlClient/SqlDataReader.cs: fix
        for various properties and methods that 
        return meta data: Item indexers this[name] and this[index],
        GetFieldType, GetName, and GetOrdinal.  SqlDataAdapter
        should work again.

2002-05-22  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data/DataRow.cs: change suggested
        by tim: in Item indexer, do an EndEdit()
        
        * System.Data.SqlClient/SqlCommand.cs: more
        fixes to SqlResult.  After setting each item in
        the DataRow, do an AcceptChanges() to commit
        the changes in the DataRow.  For DataType, use a Type
        of System.String since System.Type nor System.Object
        seems to work.
        
        * Test/TestSqlDataReader.cs
        * Test/PostgresTest.cs: updated to to be on
        the way schema table is suppose to work

2002-05-22  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data.SqlClient/SqlCommand.cs: more work on 
        building the schema table

2002-05-22  Tim Coleman <tim@timcoleman.com>
        * System.Data.SqlClient/SqlCommand.cs: preliminary work
        on getting the schema table correctly built.

2002-05-21  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data.SqlClient/ParmUtil.cs: added file - to
        provide utility for conversion of input parameters
        
        * System.Data.SqlClient/PostgresTypes.cs: added file - 
        moved the PostgreHelper class to here.  May eventually
        move the internal class PostgresTypes that's inside the 
        SqlConnection to here as well.  
        Handling of PostgreSQL <-> .NET types need to be though
        out more. Also, the PostgreHelper has a method to convert
        from .NET types to a string which can be put into used in
        an SQL statement to execute against a PostgreSQL database.
        This is the beginnings of parameters support.  It currently
        only supports input parameters.  Still need to do output,
        input/output, and return parameters.
        
        * Test/TestSqlParameters.cs: new test to test the input
        parameters in System.Data.SqlClient against a 
        PostgreSQL db.
        
        * System.Data.SqlClient/PostgresLibrary.cs: moved 
        PostgresHelper class to file PostgresTypes.cs.  Also 
        moved struct PostgresType there too.
        
        * System.Data.SqlClient/SqlCommand.cs: added input 
        parameters support
        
        * System.Data.SqlClient/SqlParameter.cs: got 
        SqlParameter to work
        
        * System.Data.SqlClient/SqlParameterCollection.cs: got 
        SqlParameterCollection to work
        
        * Test/System.Data_test.build: added files to exclude 
        from test build
        
        * System.Data.SqlClient/SqlConnection.cs: release resources
        no longer used

2002-05-18  Daniel Morgan <danmorg@sc.rr.com>

        * System.Xml: added directory for classes with namespace
        System.Xml to go into the System.Data.dll assembly
        
        * System.Xml/XmlDataDocument: added file
        for stubbed concrete class XmlDataDocument which 
        inherits from XmlDocument.  Its purpose is to provide
        a W3C XML DOM Document for relational data and interacting
        with a DataSet

2002-05-18  Daniel Morgan <danmorg@sc.rr.com>

        * 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 <danmorg@sc.rr.com>

        * 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 <tim@timcoleman.com>
        * System.Data/DataRow.cs: More implementation,
        as well as boundary checks and small semantic
        repairs

2002-05-18  Tim Coleman <tim@timcoleman.com>
        * 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 <tim@timcoleman.com>
        * 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 <danmorg@sc.rr.com>

        * 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 <tim@timcoleman.com>
        * 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 <tim@timcoleman.com>
        * 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 <danmorg@sc.rr.com>

        * 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 <tim@timcoleman.com>
        * 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 <tim@timcoleman.com>
        * System.Data/DataTable.cs:
                Construct the DataRowCollection in the DataTable
                constructor.  Otherwise, it's a null reference.

2002-05-16  Tim Coleman <tim@timcoleman.com>
        * 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 <tim@timcoleman.com>
        * 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 <tim@timcoleman.com>
        * System.Data/DataRow.cs:
                        Minor tweaks as I determine exactly how to
                                        implement this class.


2002-05-14  Duncan Mak  <duncan@ximian.com>

        * 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 <rodrigo@ximian.com>

        * 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 <danmorg@sc.rr.com>

        * 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

        * 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 <rodrigo@ximian.com>

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

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

2002-05-09  Daniel Morgan <danmorg@sc.rr.com>

        * 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 <tim@timcoleman.com>
        * 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 <rodrigo@ximian.com>

        * 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 <tim@timcoleman.com>
        * SqlString.cs:
                Fix a symantic error I made in SqlString
                Equals where I copied and pasted wrongly

                for many types

2002-05-05  Daniel Morgan <danmorg@sc.rr.com>

        * 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 <danmorg@sc.rr.com>

        * Test/PostgresTest.cs: added - ported
        libgda postgres-test.c originally by 
        Gonzalo Paniagua Javier <gonzalo@gnome-db.org>
        to C#.

                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  <miguel@ximian.com>

        * 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.

                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.

        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.

        * System.Data.build: include the System.Data.SqlTypes in the build

2002-05-03  Daniel Morgan <danmorg@sc.rr.com>

        * 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

        * 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

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

2002-05-02  Daniel Morgan <danmorg@sc.rr.com>

        * 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 <danmorg@sc.rr.com>

        * 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 <danmorg@sc.rr.com>

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

        * System.Data/MergeFailedEventArgs.cs: new class, contributed
        by John Dugaw <jdugaw@unizenconsulting.com>.

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

2002-04-29  Daniel Morgan <danmorg@sc.rr.com>

        * 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 <rodrigo@ximian.com>

        * System.Data/DataViewSetting.cs: new class.
        
2002-04-28  Rodrigo Moya <rodrigo@ximian.com>

        * 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.
        
2002-04-28  Rodrigo Moya <rodrigo@ximian.com>
        
        * System.Data/DataTableRelationCollection.cs: use 'new' keyword
        for correctly hiding parent class' members.
        (AddRange): use 'override' keyword on overriden method.
        (Clear): likewise.
        (Contains): likewise.
        (IndexOf): likewise.
        (OnCollectionChanged): likewise.
        (OnCollectionChanging): likewise.
        (RemoveCore): likewise.

        * System.Data/DataColumnCollection.cs: use 'new' keyword.

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

        * System.Data/DataRelation.cs
        * System.Data/ForeignKeyConstraint.cs
        * System.Data/UniqueConstraint.cs: added more stubs
        
        * System.Data/DataTableRelationCollection.cs: added back to cvs
        and modified for compile errors.  DataRelationCollection is an
        abstract class and there must be a class that implements for
        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.
        
        * TODO: modified - updated to do list for System.Data

        dependencies
        
        * System.Data/IDbCommand.cs
        * System.Data.SqlClient/SqlCommand.cs: modified -
        un-commented overloaded methods ExecuteReader 
        which returns a SqlDataReader

2002-04-28  Rodrigo Moya <rodrigo@ximian.com>

        * 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.
        (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 <rodrigo@ximian.com>

        * System.Data/DataTableRelationCollection.cs: removed, it's not
        on MS SDK documentation.

        * System.Data/DataTableCollection.cs: new class.

2002-04-27  Daniel Morgan <danmorg@sc.rr.com>

        * System.Data.build: modified - added new files to exclude
        from build
        
        * TODO: modified - removed files from TODO list 
        that were stubbed above
        
        * System.Data/DataColumn.cs
        * System.Data/DataRow.cs: modified - various tweaks
        and added internal method SetTable to set the reference
        to a DataTable
        
        * System.Data/DataSet.cs: modified - class was not
        completely stubbed.
        
        * System.Data/DataTable.cs: modified - temporarily commented
        DataSet and DataView references - trying to compile a SqlDataReader,
        DataTable, and dependencies for a forward read-only result set.
        SqlDataAdapter, DataSet, and DataView will come later once we can get
        a forward read only result set working.

        * System.Data.SqlClient/SqlErrorCollection.cs: modified - got
        rid of compile warnings.  Commented MonoTODO attribute because mcs

          test over and over.
        
        * System.Data.SqlClient/SqlTransaction.cs: modified - default
          IsolationLevel for PostgreSQL is ReadCommitted.  However,
          PostgreSQL allows Serializable as well. 
      (Thanks to Gonzalo for that!)
        
        * System.Data.SqlClient/SqlConnection.cs: modified
        * System.Data.SqlClient/SqlCommand.cs: modified
        * System.Data.SqlClient/SqlTransaction.cs: modified - got transactions

          status and error message support from the PostgreSQL database.
          Currently, this does a Console.WriteLine() to display the
          status and error messages, but this is a TODO 
          for SQL errors and exceptions.
