what is the Difference between DDE and OLE?

Answer Posted / asif

DDE (Dynamic Data Exchange) a communication protocol that
let applications call each other.OLE was the first protocol
that enabled users and programmers to create compound
documents—that is documents that contain data from different
applications (for example an Excel worksheet inside a Word
document). Depending on the application's needs compound
documents can completely encapsulate other simpler documents
(embedding) or contain simply a reference to existing
documents (linking). When the user clicks on an embedded or
linked document inside a compound document Windows runs the
application that's capable of dealing with that particular
type of document.
