web.config ตั้ง Connection Oracle ยังงัยครับ ลองหลายแบบแล้วไม่ได้สักที...

<connectionStrings>
	<add name="OracleConnectionString" connectionString="Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;Integrated Security=no;" providerName="System.Data.OracleClient"/>
</connectionStrings>

Imports System.Web.Configuration
Imports System.Data.OracleClient

Dim connectionString As String = WebConfigurationManager.ConnectionStrings("OracleConnectionString").ConnectionString
Dim connection As New OracleConnection(connectionString)
