Regarding Error [Microsoft][ODBC Driver Manager]Data source name not found and no default driver specified.

 

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.
