Similarities

They have these characteristics in common:

• Icon or contents

  The DataWindow object can display the OLE object as an icon, or
  it can display an image of the contents when display of contents
  is supported by the server.

• Data from the DataWindow object

  You specify which DataWindow columns you want to transfer
  to the OLE object. The data that is sent to the OLE server replaces
  the OLE object template specified in the painter.

Differences

The OLE object in a DataWindow object and the OLE presentation style
have these main differences:

• Associating the object with rows

  When the OLE object is added to a DataWindow object, you can associate
  it with individual rows, groups of rows, or all rows. In the presentation
  style, the OLE object is always associated
  with all rows.

• Properties view

  The Properties view for an OLE object has different pages
  and some different properties from the OLE DataWindow object. For example,
  the Properties view for an OLE object in a DataWindow object does not contain
  detailed print specification settings because these are set in the DataWindow object’s
  own Properties view. However, it does have settings related to the
  position of the OLE object within the DataWindow object.

The features of the OLE server application determine whether
it can provide useful information in a DataWindow object.

If the server does not support display of contents, it is
not useful for objects associated with rows. The user sees only
the icon. Some servers support the display of contents, but the
view is scaled too small to be readable even when the object is
activated.
