All I could find is a simple example and a manual in VB which is not the same objects as Delphi.
Edit: So there is no manual. Where could I find the code that translates the Delphi code to access the OLE calls? In the current state, there is a guessing game with the Delphi as , how vb is translated to the Delhpi.
The authoritative source is the Word Object Model Reference on MSDN. There is nothing better. It's not written using Delphi syntax but you just have to live with that.
