    In This Topic

    dotConnect for DB2 integrates tightly with design-time features of Visual Studio 2008, 2010, 2012, 2013, 2015, 2017, and 2019 such as Server Explorer. This is also mentioned as Data Designer Extensibility features, or DDEX. The integration helps to design applications in more convenient and fast way. For example, you can take advantage of DataSet Designer, Data Source wizard, Query Builder, TableAdapter configuration, use Preview Data capability and configure web SqlDataSource component.

    This topic provides information on what new features are available and how to use them.

    Note that Server Explorer integration is not available for Compact Framework projects and in Visual Studio Express editions except Microsoft Web Developer Express 2008 and 2010.

    This article consists of the following sections:

    Integrating with Server Explorer

    Server Explorer is the server management console for Visual Studio. Use this window to open data connections and to log on to servers and explore their databases. With Server Explorer you can view and retrieve information from all of the databases you are connected to. Use Server Explorer to list database tables, views, stored procedures, functions, and expand individual nodes to list their columns or arguments. Connections created with Server Explorer are later available in other parts of Visual Studio such as Data Designers.

    To access Server Explorer, choose Server Explorer on the View menu.

    Add Connection dialog box

    This dialog box allows you to create and modify database connections. There are three ways to access this dialog box:

    • From the Tools menu select Connect to Database.
    • Right-click the Data Connections node in Server Explorer and click Add Connection.
    • Right-click the data connection you want to modify in Server Explorer and click Modify Connection.

    The dialog consists of several controls where you supply information needed to connect to server. The following list describes the most important controls.

    Server
      The name or IP address of host of DB2 database (and port, separated from the name or IP with a semicolon, if necessary) to which to connect.
    User Id
      The DB2 login account.
    Password
      The password for the DB2 login account.
    Allow saving password
      If set to true password is stored among the other connection parameters.
    Database
      Select name of DB2 database you want to connect from drop down list or enter it manually.
      List is available only if you specify other connection parameters.
    Schema
      The schema to use in database operations.

    After you fill the controls with data click Test connection button to verify it or click OK button to apply changes and close the dialog.

    The Advanced Properties dialog box allows you to specify all properties for the dotConnect for DB2 connection. Invoke this dialog when you need to set specific and rarely used connection parameters.

    Design-time integration with project data

    The Data Source Configuration Wizard creates and edits data sources in your application. These data sources can be made from databases, Web services, or objects, and can be bound to controls that display data on forms. After you run the wizard, the data source is available in the Data Sources window for dragging onto forms in Windows applications. For example, the wizard can generate and add DataSet to your project, which can be later customized with TableAdapter Configuration Wizard.

    You can run the Data Source Configuration Wizard in any of the following ways:

    Data Source Configuration Wizard

    When wizard starts, choose Database as data source type, and click Next. Then choose Dataset, and on the next page click the New Connection button. Change data source to DB2 Server, provide logon information and click OK. After that you will have to choose whether to save sensitive information together with other parts of connection string in application configuration file. On the last page of the wizard you select database objects to include in dataset.

    On wizard completion you can switch to Solution Explorer to manipulate generated datasets.

    The TableAdapter Configuration Wizard creates and edits TableAdapters. The wizard creates TableAdapters based on SQL statements you enter or on existing stored procedures in the database. The wizard can also create new stored procedures in the database based on SQL statements you enter into the wizard.

    A TableAdapter connects to a database, executes queries or stored procedures against a database, and fills a DataTable with the data returned by the query or stored procedure. In addition to filling existing data tables with data, TableAdapters can return new data tables filled with data.

    A parametrized query returns data that meets the conditions of a WHERE clause within the query. For example, you can parametrize a customer list to display only customers in a certain city by adding WHERE City = ? to the end of the SQL statement that returns a list of customers. You create parametrized TableAdapter queries in the DataSet Designer, or during creation of data-bound forms in a Windows application with the Parametrize Data Source command on the Data menu. The Parametrize Data Source command also creates controls on your form to input the parameter values and execute the query.

    This wizard is similar to common Data Source Configuration Wizard. To open it from an ASP.NET Web server control perform the following:

    If you experience problems with using Visual Studio windows related to tasks described above just press F1 to open Visual Studio documentation.

    If you wish to study more detailed the capabilities of Visual Studio integration you can pay attention to Creating Client Data Applications section in Visual Studio Help. dotConnect for DB2 provides integration capabilities similar to standard data providers.
