This tutorial is based on the Simple project that is included with SQL Anywhere 10.
The complete application can be found in your SQL Anywhere samples directory at samples-dir\SQLAnywhere\ADO.NET\SimpleWin32.
For information about the default location of samples-dir, see Samples directory.
The Simple project illustrates the following features:
connecting to a database using the SAConnection object
executing a query using the SACommand object
obtaining the results using the SADataReader object
basic error handling
For more information about how the sample works, see Understanding the Simple sample project.
Start Visual Studio .NET.
Choose File > Open > Project.
Browse to samples-dir\SQLAnywhere\ADO.NET\SimpleWin32 and open the Simple.sln project.
When you use the SQL Anywhere .NET Data Provider in a project, you must add a reference to the Data Provider DLL. This has already been done in the Simple code sample. You can view the reference to the Data Provider DLL in the following location:
In the Solution Explorer window, open the References folder.
You should see iAnywhere.Data.SQLAnywhere in the list.
For instructions about adding a reference to the Data Provider DLL, see Adding a reference to the Data Provider DLL in your project.
You must also add a using directive to your source code to reference the Data Provider classes. This has already been done in the Simple code sample. To view the using directive:
Open the source code for the project. In the Solution Explorer window, right-click Form1.cs and choose View Code from the popup menu.
In the using directives in the top section, you should see the following line:
This line is required for C# projects. If you are using Visual Basic .NET, you need to add an Imports line to your source code.
Choose Debug > Start Without Debugging or press Ctrl+F5 to run the Simple sample.
The SQL Anywhere Sample dialog appears.
In the SQL Anywhere Sample dialog, click Connect.
The application connects to the SQL Anywhere sample database and puts the last name of each employee in the dialog, as follows:
Click the X in the upper right corner of the screen to terminate the application and disconnect from the sample database. This also shuts down the database server.
You have now run the application. The next section describes the application code.
