    Summary:   Object Linking and Embedding  (OLE) is like Dynamic
    Data Exchange (DDE) in that it enables you to access objects that
    are stored in another product. However, instead of requesting
    data from another product, OLE lets you use the other product as
    if it were an extension of Superbase.

    Superbase can ONLY be an OLE CLIENT APPLICATION. It CANNOT be an
    OLE SERVER APPLICATION. There are two types of OLE objects that
    can be created in Superbase: embedded and linked.

    Embedded objects

    An embedded object contains a copy of the data in the server
    file. Once you embed an object, the data in the object no longer
    has any connection to the data in the server file from which it
    was copied. Any changes made to the object in Superbase are NOT
    reflected in the server application, and vice versa.

    Linked objects

    A linked object contains data that is linked to the server
    application and server file. When you link an object, it remains
    connected to the original data in the server file.  Changes made
    to the object in Superbase ARE updated in the server application,
    and vice versa.

    To embedding a new OLE object, follow the steps below.

    1. In Superbase, open a datafile that contains an external field.

    2. Fill in the various fields, and when the cursor is positioned
       in the external field, click  Edit\Insert embedded object.

    3. A list of recognized servers appears.

    4. Select a server.

    5. In the Server application, prepare the object. You could also
       "paste" it from another object in the server application.

    6. Exit; you must close the server application.

    7. Answer "Yes" to update the embedded object.

    8. In Superbase, complete and Save the data.

    To link objects, follow the steps below.













    1. Start the server application.

    2. Start Superbase.

    3. In the Server application, load the existing object. Mark the
       object, and do an Edit\Copy.

    4. Switch to Superbase, and when in the external field, select
       Edit\Paste special. This shows you a list of open servers.

    5. Select the correct one for the server application. Select
       Paste link.

    6. Fill in the rest of the data and then Save the Superbase
       record.

    Viewing OLE objects

    To view an embedded or linked OLE object, click  the external
    file icon.  This is the camera icon on the panel. (You could also
    choose Next External from the menus). The icon for the OLE object
    displays.  Double-click the OLE object to view and edit it.
