EDBDataAdapter adap = new EDBDataAdapter("select * from databases", con);
DataTable tbl = new DataTable();
adap.Fill(tbl);

Workaround:

EDBDataAdapter adap = new EDBDataAdapter;
adap.SelectCommand = new EDBCommand;
adap.SelectCommand.Connection = con;
adap.SelectCommand.CommandText = "select * from databases";
DataTable tbl = new DataTable();
adap.Fill(tbl);
