Dear friends,

I am developing one asp.net application which is using oracle as a Back End. I am new to Oracle. While connecting asp.net with oracle, It throws the following error.

No error information available: REGDB_E_CLASSNOTREG(0x80040154).
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.OleDb.OleDbException: No error information available: REGDB_E_CLASSNOTREG(0x80040154).

My connection coding is like follow:

Dim con As New OleDbConnection
 con.ConnectionString = "Provider=OraOLEDB.Oracle; Driver={Microsoft OLE DB for Oracle};Data Source=orcl;User Id=scott;Password=tiger;"
 con.Open()

Pls help me.

Dont use Microsoft OLE DB for Oracle
Instead Try
ConnectionString="OleDB:Provider=MSDAORA.1;Data Source=myserver.com;User ID=scott;Password=tiger;

give your correct data source and user id and password.

ConnectionString="Provider=MSDAORA.1;Data Source=myserver.com;User ID=scott;Password=tiger;
give your correct data source and user id and password
