In this session, we've seen the theory and concepts behind DDE, and we've looked at few examples, which illustrated how PowerBuilder can be used both as DDE client and server.
Whilst DDE is a useful technology. At times it can be complex, as you may have seen in some examples. In the next session, we'll look at another method of inter-process communication; Object Linking and Embedding (OLE). We'll look at the concept behind this fairly new technology and again provide you with some examples to illustrate just how easy it is to use OLE compared to the old standard of DDE.
For a complete summary of this session, browse 'dde.ppt' , a PowerPoint presentation.
