To eliminate the need to qualify the objects fully in code, add an Imports System.Data.OracleClient statement (Visual Basic) or using Sys tem.Data.OracleClient; statement (C#) to the top of your code file.

In this lab you will practice creating new Data Connections in Server Explorer and using the Data Source Configuration Wizard.
Exercise 1: Creating Connections in Server Explorer
The following steps describe how to create a Data Connection (a connection to a data base) in Server Explorer. 1. If the Server Explorer window is not visible, select Server Explorer from the View menu. 2. Right-click the Data Connections node and select Add Connection. The first time you add a connection in Visual Studio, the Choose Data Source dialog box opens.
NOTE Add Connection Dialog Box
If the Add Connection dialog box opens instead of the Choose Data Source dialog box, click the Change button located at the top of the Add Connection dialog box.
The Choose Data Source dialog box (or the similar Change Data Source dialog box) is where you select the data source you want to connect to, as well as the data provider to use for the connection. Notice how the proper data provider is auto matically populated when you select different data sources. You can choose any valid provider you want for any selected data source, but Visual Studio automati cally selects the most appropriate data provider based on the selected data source. For our first connection, we ll create a connection to the Northwind Traders sam ple database in SQL Server.
Lesson 1: Creating and Configuring Connection Objects
3. Select Microsoft SQL Server for the data source and click OK. The Add Connection dialog box now appears with Microsoft SQL Server as the selected data source.
NOTE .NET Framework Data Providers
The .NET Framework Data Provider for SQL Server is designed to connect to SQL Server 7 and later versions. When connecting to SQL Server 6 or earlier, highlight the <other> data source and select the .NET Framework Data Provider for OLE DB. Then, in the Add Connec tion dialog box, select the Microsoft OLE DB Provider for SQL Server.
4. Type the name of your SQL Server in the server name area. 5. Select the appropriate method of authentication to access your SQL Server. 6. Choose Select or enter a database name option and select the Northwind data base from the drop-down list. 7. You can verify the connection is valid by clicking Test Connection and then click ing OK to close the dialog box and create the connection in Server Explorer. After creating the connection, the Properties window provides information related to the connection as well as information related to the actual database you are connected to. 8. Select the connection you just created in the Server Explorer window to view the available information in the properties window.
NOTE Connection Properties
The available properties are based on the type of data source you are connected to as well as the state of the connection. If the connection is closed, you might see only a small list of properties made up of the connection string used to connect to the database, the specific .NET Framework data provider used by the connection, and the state of the connection. To view additional properties, it is necessary to open the connection by expanding the connec tion node in Server Explorer. Once open, the connection provides additional properties such as the database owner, whether the database is case sensitive, and the type of database and version number.
