DataDirect product documentation is provided in PDF format, which allows you to view the books online or print them. You can view DataDirect online documentation using Adobe Acrobat Reader 4.x or higher. DataDirect product documentation is also available on the DataDirect Technologies Web site:

On Windows, you have the option of installing the online books on your system. When installed, they are located in the books directory that is created within the SequeLink installation directory.

When you install the JDBC or ODBC Client, HTML-based online help for developing applications is placed by default in the help directory that is created beneath the SequeLink installation directory. To access help, you must have Internet Explorer 5.x or higher, or Netscape 4.x or higher, installed. (Netscape 6.0. does not support the help system; however, 6.1 or higher does.) After you have opened the main screen of the help system in your browser, you can bookmark it in the browser for quick access later.

On Windows platforms, help is available from the setup dialog box for each driver. When you click Help, your browser opens to the correct topic, without opening the help Table of Contents. A grey tool bar appears at the top of the browser window.

If, after viewing the help topic, you want to see other help topics, clicking:

on the left-hand side of the toolbar opens a left pane and displays the Table of Contents, Index, and Search tabs for the entire help system.

Alternatively, you can access the entire help system by selecting the help icon that appears in the SequeLink program group.

When you install the .NET Client, a compiled help file (.CHM) is placed on your system in the help subdirectory of the installation directory. The program group for DataDirect SequeLink Client for .NET contains an icon for launching the help system.
