Hi
I am attempting to write a C application which interacts with IDL
using the IDL DDE routines (viz dde_getservers(), dde_gettopics() ...)
under windows.
I started by using a simple DDE server application written by Borland
(1992), in Borland C, which communicates with a DDE client using the 3.1
api DDEML calls.
The problem I have is that 'dde_getservers()' produces a null result
when DDESRVR.EXE is running. In fact, with the exception of Word for
Windows, every DDE server application that I have tried (which is
quite a few) is not recognised as being 'out there' by a call to
'dde_getservers()'.
This seems to indicate that these applications are not using the DDE
conventions expected of them by IDL, or I am doing something wrong.
I have been in contact with CreaSo for the last two weeks and their
only response was to advise me to get a book by Peter Norton on DDE's
(no title, no publisher).
The ideal would be if someone could point me to source code for a
skeleton of a DDE server application (compilable under Borland C,
preferably) which can communicate with IDL using the IDL DDE routines.
Otherwise any help or pointers would be gratefully received.
