Hi Team,
In our project, we are using ODBC driver for connecting oracle database.
When we are running the application in Windows 7 Professional Edition, It is showing an error that [Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified.
We are using a DSN less connection and the connection string in the web.config file is
"<connectionStrings>
<add name="xxxx" connectionString="server=xxxx; user id=xxxx; password=xxxx"
providerName="System.Data.OracleClient" />
</connectionStrings>"
The connection string used for VB pages is
<ConnectionString>
Provider=OraOLEDB.Oracle;Password=xxxx;User ID=xxxx;Data Source=xxxx;
</ConnectionString>

Thanks in Advance.

If you're using .NET try looking into .NET Framework Data Provider for Oracle in

http://connectionstrings.com/oracle[^]

[Standard]
Data Source=MyOracleDB;Integrated Security=yes;

[Specifying username and password]
Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;Integrated Security=no;
