Thanks. We'll let you know when a new response is added.

Have a look at the following Oracle article for the basics on connecting to the database from .NET

It shows how to connect to the database and retrieve records using SELECT statements. To perform inserts and updates you just need to change de command text with the appropriate SQL command, and execute it as non reader (i.e. replacing cmd.ExecuteReader with cmd.ExecuteNonReader).

In .NET, everything have to be inside a class or module (excluding the imports). Also, there are some unnecessary lines in your code, for example the lines where you set the connection string. If you want to avoid the use of the TNSNAMES.ORA file then use your second option: Dim oradb As String = “Data Source=(DESCRIPTION=" _ + “(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))” _ + “(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ORCL)));” _ + “User Id=shazia;Password=shazia;” Otherwise, use this (but replace 'localhost' with the database alias defined in your tnsnames.ora file): Dim oradb As String = “Data Source=your_database_alias;User Id=shazia;Password=shazia;” Your code should look similar to this: Imports Oracle.DataAccess.Client Public Class MainClass Shared Sub Main() Dim oradb As String = “Data Source=(DESCRIPTION=" _ + “(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))” _ + “(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ORCL)));” _ + “User Id=shazia;Password=shazia;” Dim conn As New OracleConnection(oradb) conn.Open() End Sub End Class
