[Mono-list] ODBC.NET Provider on Windows

I have tried to get the Odbc.net provider to use Microsoft Window's native
ODBC library which is odbc32.dll by changing the DllImport from "libodbc" to
"odbc32".  The library apparently loads,
but I don't know what the errors are for.

Any ideas?

This is the results I got:

DanielMorgan@DANPC ~/mono/mcs/class/System.Data/Test
$ mono OdbcTest.exe

I have a ODBC.net test named OdbcTest.cs that works on Windows XP
using .NET 1.1 Beta, but not Mono:

using System;
using System.Data;
using System.Data.Odbc;

namespace Test.OdbcTest
	class OdbcTest
		static void Main(string[] args)
			OdbcConnection dbcon = new OdbcConnection();
			// connection string to a Microsoft SQL Server 2000 database
			dbcon.ConnectionString =
				"DRIVER={SQL Server};" +
				"SERVER=(local);" +
				"Trusted_connection=true;" +


			OdbcCommand dbcmd = new OdbcCommand();
			dbcmd.Connection = dbcon;
			dbcmd.CommandType = CommandType.Text;
			dbcmd.CommandText = "SELECT lname FROM employee";

			OdbcDataReader reader;
			reader = (OdbcDataReader) dbcmd.ExecuteReader();

			while(reader.Read()) {
				Console.WriteLine("Last Name: " + reader[0].ToString());
