What is DDE? It sounds like an ancient acronym of the Windows 3.1 times.

What is it for? Isn't it superseded by OLE?


I've read (better say, looked through) an article somewhere that Ada is 
well suited for DDE.

I found some references to DDE here, but unfortunatly when following
links, I ended up with a screen in german that wanted me to apply for
a mail account (I think). Maybe I should have asked Gautier directly,
but I thought that maybe someone else got benefit from the answer.

You are probably right that there are better ways to do this, but
searching the group for OLE doesn't help much. The idea of using DDE
is inspired by my interest for Tcl/Tk, which have a package for DDE.

(I have also used Gautier's excellent Excel_Writer.)

You're about right:

The easiest method of sharing across processes on the same machine is 
simple shared memeory/file mapping.  Across network, I sometimes use 
pipes.  There are more complicated (sophisticated ha) methods.

If I can control both sides, I am perfectly happy with TCP/IP. My
hobby application (a Bridge deal generator) has a GUI coded in Tcl/Tk
communicating with the application written in Ada uses this technique,
which I learned from my customer, keeping GUI and application.

Now after trying Excel_Writer, I would like to do more sofisticated
things with my excel output.

Sure, the present version is extremely basic, the potential for 
improvement is huge :-). Still, it is in some contexts way more 
convenient than outputting a CSV file that you always need to reformat 
in Excel in order to see something. And it is good for impressing your 
colleagues with nicely formated automatic reports.
Back to your original question, I sent you the DDE stuff per e-mail. It 
includes an example with some Excel interaction.

Thanks, Gautier!

Excel_writer is very good ie on embedded systems where you obviously
often do not have excel. CSV files do not offer any formatting at all
and also headings are just data aswell.

I am now trying to find a usable win32. I did not think this through
enough to realise I need that too.

Gautier, is your DDE stuff publicly available?  I'd like to get a copy, too!
