In Powerpoint 2010, you can go to Menu->File->Edit Links to Files,
and for each external link, there are two radio buttons at the bottom
of the window, ‘Automatic’, ‘Manual’, which you can choose to indicate
if the linked OLE object image will be updated automatically or manually
upon opening of the file.
When using Aspose.Slides to set the OLE object link with OleObjectFrameEx.setLinkFilePath() method, is it possible to set whether the linked OLE object will be updated automatically or manually?
I attached a screenshot file. As you can see, Powerpoint allows you to set ‘automatic’ or ‘manual’ on an OLE link so the link can be either updated automatically or manually.
