LinkFormat Object

Represents the linking characteristics for an OLE object or picture.
Using the LinkFormat Object
Use the LinkFormat property for a shape or field to return a LinkFormat object. The following example updates the links to all linked OLE objects on the first page of the active publication.
Sub FindOLEObjects()
Dim shpShape As Shape
For Each shpShape In ActiveDocument.Pages(1).Shapes
If shpShape.Type = pbLinkedOLEObject Then
shpShape.LinkFormat.Update
End If
Next shpShape
End Sub
Remarks
Not all types of shapes and fields can be linked to a source. Use the Type property for the Shape object to determine whether a particular shape can be linked.
Use the Update method to update links. To return or set the full path for a particular link's source file, use the SourceFullName property.
