I'm trying to pass data in and out of Excel using DDE.  The Borland OWL package
made it easy to connect -- but... the DdeGetData call moves data into my
buffer, but I can't figure out what the data means.  The sample program
supplied by Borland just passes text.  The windows.h file defines several
"clipboard format" types - but it doesn't define the type Excel uses.  My
Excel documentation only describes the Excel commands - no clue as to the
data format.

Any help in how to track down the "oxcboa" clipboard format is appreciated.
Thanks - arm

Excel tries to use several types.  It starts (I think) with CF_BIFF and
then wanders through a variety of formats until it eventually reaches
CF_TEXT.  All you need to do is to NACK the format(s) you don't
understand and Excel will try again.  I can't find a code fragment
offhand, but this should point you in the right direction.
