Hi All,

I am trying to createprocess with an  application whose registry setting is
c:\Program Files\Appx.exe /dde
This app opens files of  type .pqr.

Calling CreateProcess("c:\\Program Files\\Appx.exe","Appx.exe //dde
c:\\Filex.pqr"...
works and Filex.pqr opens.

However if i wish to call again with a different file, (Appx has not been
closed),
CreateProcess("c:\\Program Files\\Appx.exe","Appx.exe //dde
c:\\Filey.pqr"...

then a new process is opened and a second instance of Appx.exe opens- and
NOT as i would like, dde to take over, and open the second file in the first
called instance of Appx.

When i open the files direct from explorer, Filex.pqr, and then Filey.pqr,
Appx.exe opens as a single dde program, which is exactly the behaviour i
would like to mimic with createprocess.

Is there a simple solution to this, or must i go deeper. i've looked at the
ddeexcec key, but could find nothing useful.
I use the process data from Createprocess so other ways of opening the app
are of no use to me.

Any help on this would be more than welcome. Thanks in advance, Angus.
