Connect ORACLE database with sysdba privileges

Question

Hi Guru,
I am connecting to my ORACLE database with my VB application.
I have problem with connecting to the database with SYSDBA privileges. i.e it is not connecting to the database with SYSDBA privileges.
If I connect my db from SQLPLUS. Its worked like this..
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
SQL> select Name from v$datafile;
select Name from v$datafile
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> connect as sysdba;
Enter user-name: user_1
Enter password: ****
Connected.
SQL> select Name from v$datafile;
NAME
C:\NEW\ORADATA\ITPL\SYSTEM01.DBF
C:\NEW\ORADATA\ITPL\UNDOTBS01.DBF
C:\NEW\ORADATA\ITPL\CWMLITE01.DBF
C:\NEW\ORADATA\ITPL\DRSYS01.DBF
C:\NEW\ORADATA\ITPL\EXAMPLE01.DBF
C:\NEW\ORADATA\ITPL\INDX01.DBF
C:\NEW\ORADATA\ITPL\ODM01.DBF
C:\NEW\ORADATA\ITPL\TOOLS01.DBF
C:\NEW\ORADATA\ITPL\USERS01.DBF
C:\NEW\ORADATA\ITPL\XDB01.DBF
10 rows selected.
SQL>
Now in my VB application if I am using following string to connect the database.
m_adoCnn.ConnectionString = Provider=MSDAORA;Password=pass;User ID=user_1;DBA Privilege=SYSDBA;Data Source=ITPL
It will connect properly to the database but gives error while executing the query select Name from v$datafile;
as,
ORA-00942: table or view does not exist
Can any body help me in this or provide me proper connection string.
