re: Having hard time with Microsoft ODBC connection to Oracle

Hello,
Could anyone please tell me what do I need to do in order to connect to Oracle 11g through VB script. I already had my tnsnames.ora file set up on my machine and I was able to TNSPING to the Oracle 11g database and I was also able to SQLPLUS mylogin/mypassword@database. Both TNSPING and SQLPLUS are working. I also was able running successfully test the microsoft ODBC administrator on my machine which was successfully connect to the the Oracle database. My question is that what do I need to do or what else do I need to install in order to run successfully this connection string from my VB script.

strCon = "Driver={Microsoft ODBC for Oracle}; " & _
'' "CONNECTSTRING=(DESCRIPTION=" & _
'' "(ADDRESS=(PROTOCOL=TCP)" & _
'' "(HOST=" & dbhost & ")(PORT=1521))" & _
'' "(CONNECT_DATA=(SERVICE_NAME=" & UCase(sDomain) & "test.com))); uid=myid;pwd=" & mypassword & ";"

When I ran it, it said the microsoft ODBC driver for oracle not defined. I don't understand why and what I need to do ?

Thanks,
Mi
