Hi, I've been trying to go through the MSDN docs, and do general googling, but I'm having trouble finding simple, plain language explanations of what these terms mean, how they're related, how they're different, and pros/cons of each. You don't have to explain everything, any info would be appreciated: - DDE - OLE - OLE2 - COM - DCOM - ActiveX - ADO Also, which of the above are "obsolete", and what newer technologies replace or are built on the above? Thanks, Brian

DDE: dynamic data exchange. Older method of Win32 IPC (interprocess communication) where applications send messages and start servers to listen for messages being broadcast.

OLE: object linking and embedding. Technology that lets you edit a Microsoft Excel spreadsheet from within a Word document, complete with menu bars changing dynamically and everything.

OLE2: the above, version 2.0. (I don't know what it adds)

COM: component object model. This is a standard binary layout for objects so that objects (called components) can be used regardless of programming language. It is the de facto standard for Win32 components pretty much.

DCOM: distributed COM. Similar to COM, but objects can be spread across the network and are able to communicate with other COM objects, regardless of whether the other objects are in-process, out-of-process (but on the same box), or on another computer entirely.

ActiveX: a COM object that Internet Explorer is capable of hosting directly within the browser that looks and acts like a Windows control.

ADO I don't know off the top of my head.
