ODBC Connectivity to FM Pro

I had written an ODBC connector to FM Pro using VB.NET application, where I get data via following two lines that work just fine.

connection.Open("Provider=MSDASQL.1;Data Source=FMTest;User ID=sa;Password=sa;")

recordset.Open("Select * from PMProTest.fp7", connection)

where, connection and recordset are initialized as follows:

Dim connection As ADODB.Connection = new ADODB.Connection

Dim recordset As ADODB.Recordset = new ADODB.RecordSet

However, writing a similar application using C# is failing with exception System.Data.Odbc.OdbcException: [iM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

The C# code looks like this:

// Note: all Odbc* classes are from System.Data.Odbc namespace.

m_Command = new OdbcCommand();

m_Connection = OdbcConnection("Provider=MSDASQL.1;Data Source=FMTest;User ID=sa;Password=sa;")");

m_Connection.Open();

m_Command.Connection = m_Connection;

......

......

m_Command.CommandText = "Select * from PMProTest.fp7";

m_DataReader = m_Command.ExecuteReader(CommandBehavior.Default);

......

......

Anyway, the exception is thrown at call to m_Connection.Open() . Anybody has any idea what I am doing wrong? Only difference between the two application is that I am using ADODB (version 2.8) control in VB and included System.Data.Odbc reference and namesspace in c# solution and code.

Thanks,

Raja.
