Connecting to Oracle 9i Lite from VB.NET ODBC

[Andrew McGregor]

Hi,

I am trying to get a VB.NET application to connect to a local Oracle 9i Lite
database.

What is the correct form for a connect string?

cn = New
Microsoft.Data.Odbc.OdbcConnection("dsn=POLite;Trusted_Connection=yes;User
Id=SYSTEM;Password=MANAGER")

raises the following exception:

could not open oracle connection: Microsoft.Data.Odbc.OdbcException: ERROR
[S1000][POL-2200] failed to create mapped file
ERROR [IM006] [Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr
failed
ERROR [01000] [Microsoft][ODBC Driver Manager] The driver doesn't support
the version of the ODBC behaviour that the application requested (see
SQLSetEnvAttr)
at Microsoft.Data.Odbc.OdbcConnection.Open

I have also tried the following:

cn = New Microsoft.Data.Odbc.OdbcConnection("Driver={Oracle Lite 40 ODBC
Driver};DataBase=mobile;User Id=SYSTEM;Password=MANAGER;Persist Security
Info=False;DSN=POLite")

which provides a more serious failure:

OracleLiteTest.exe has encountered a problem and needs to be shut down.

and

could not open oracle connection: Microsoft.Data.Odbc.OdbcException:
ERROR - no error information available
at Microsoft.Data.Odbc.OdbcConnection.Open

Server Explorer displays some Data Connections, am I incorrectly mixing OLE
and ODBC?

Regards,

Andy

Hi Andrew,

Yes it does, thank you. It proves that my first attempt was correct,
and I should of trusted the exception .NET captured, POL-2200.

I am concerned that I am even getting a POL-2200 exception at all on
any modern system, but that is for an Oracle or XP discussion.

Many thanks.

Andy
