ADO/WFC provides a sophisticated array of data access services, allowing the Visual J++ developer to create rich, data-centric applications. To help you get started using ADO/WFC, this section provides the following set of programming samples:
| Sample | Description | Components Used |
| Framework Code | Provides a runnable framework in which to copy the code examples. | |
| Connection Sample | Connects to a data source and executes a simple query that results in a forward-only, server cursor. | Connection |
| Recordset Sample | Opens a disconnected Recordset and populates it with the results of a data source query. Performs several Recordset-oriented operations, such as adding, deleting, updating, and canceling local updates. Note that this is a large code sample. You should thoroughly understand the Connection object before trying this sample. | Connection, Recordset, AdoProperty, AdoProperties (collection) |
| Command Sample | Uses a Command object to execute a query with parameters. This is a performance optimization mechanism for highly repetitive operations that vary only in the value of the parameters to the operation. | Connection, Recordset, Command, Parameter |
| Asynchronous Command Execution Sample | Uses asynchronous mode to allow background population of a cursor. | Connection, Recordset, ConnectionEventHandler |
| Transaction Sample | Uses transaction and isolation levels to control data change visibility in applications. Ensures changes are committed or aborted. | Connection, Recordset, Transaction |
| DataSpace Sample | Invokes business objects on an application server using the Remote Data Services (RDS) and Internet Information Server (IIS). Marshals the Recordset result back using SOAP (Simple Object Access Protocol). | Connection, Recordset, ObjectProxy, DataSpace |
| Event Handling Sample | Hooks up event handlers to process changes in Recordsets, allowing all interested “listeners” to track changes. | Connection, Recordset, RecordsetEventHandler, RecordsetEvent |
| Data Navigation Sample | Opens a Recordset and navigates through its cached data. Examines the metadata of the Recordset by iterating through the Fields collection of the Recordset. | Connection, Recordset, Field, Fields (collection) |
Note You should begin with the Framework Code sample, which shows how to set up your application. You can then use the code in the other samples to add the desired functionality.
