	//problems from Synergy

	//Ofer, 

	//Take a look at #1. Test this to see if we have a problem in dispose. If we do, add a test for this to make sure we catch it in next rounds.

	//Subject: 2 problems from Synergy


	//Please check those 2 problems reported by Synergy and tell me what do you think.

	//1) The following code works in dotnet but doesn//t work in j2ee.
	//// Oracle Drivers
	//OleDbConnection Connect;
	//OleDbDataReader DbReader;
	//OleDbCommand DbCommand;
	//IDataReader DR;
	//string sSQL;
	//int iField;
	//bool bFound;
	//try
	//{
	//Connect = new OleDbConnection("Provider=\"MSDAORA.1\";User
	//ID=COM;Password=SQL;Data Source=LLO1;HostName=WS10359;Port=1521");
	//Connect.Open();
	//sSQL = "SELECT * FROM PRODUCT WHERE PRO_SKU = //SKU_208//";
	//DbCommand = new OleDbCommand(sSQL, Connect);
	//DbReader = DbCommand.ExecuteReader(CommandBehavior.SingleRow);
	//DR = DbReader;
	//DbCommand.Dispose(); // comment out
	////DbCommand = null;
	//bFound = DbReader.HasRows;
	//DR.Read();
	//// Get Column Ordinal
	//iField = DR.GetOrdinal("PRO_DESCRIPTION");

	//string sDesc = DR.GetString(iField);
	//}
	//catch(Exception e)
	//{
	//this.WriteErrorLog(e.Message);
	//}
	//i have identified the problem as being "DbCommand.Dispose()". If you comment this line out or make it 
	//"DbCommand = null", then its okay. So this instruction doesnt work the same in both in .net and j2ee.


	[Test]
	public void run()
	{
		Exception exp = null;

		//OleDbConnection  con = null;

		//this test was added due to a request from Oved:
		//this bug occur on all databases (SQL,Oracle,DB2)
		OleDbCommand DbCommand = null;
		OleDbConnection Connect = new OleDbConnection(MonoTests.System.Data.Utils.ConnectedDataProvider.ConnectionString);
		Connect.Open();
		DbCommand = new OleDbCommand("SELECT * FROM Customers", Connect);
		OleDbDataReader  DbReader  = DbCommand.ExecuteReader();

		BeginCase("Check DataReader.IsClosed - before dispose");
		try
		{
			Compare(DbReader.IsClosed,false); //.Net=false, GH=false
		}
		catch (Exception ex){exp = ex;}
		finally{EndCase(exp);exp = null;}
