I have a windows based application which can generate letters in Word and/or
insert data into Excel spread sheets. For the letters, we use .dot files as
input. The .dot files also contain WordBasic macros to process the mail
merger. We pass commands and data to a third party software app, which in
turn issues the DDE processing.

We would like to skip the third party software, and convert from DDE to OLE.
Our source data is generated on the fly. I have not been able to gather
enough info from any Microsoft source to determine a conversion approach. Is
there any ready samples, links, etc. for doing this conversion? Or any hot
tips? We do the development work on the windows app, so we will be doing the
conversion in house.
