You can't use CreateProcess() to initiate DDE conversations.  You can try
using ShellExecute(), though, specifying just the filename and letting the
OS decide which application to run and how to pass the filename to it.

Double-clicking a file in Explorer invokes ShellExecute().

That is because you probably did not understand what it was telling you.  It
is actually quite helpful, but requires a lot of extra work on your part in
order to actually utilize it.  Better to let ShellExecute() do the work for
you.

You cannot use CreateProcess() for what you are asking.  It does not support
DDE.  What process data are you using exactly?  Perhaps you can obtain it
through other means.
