Complete implementation of DDE (DDEML) Client as Python module. Works with Python 2.6 and 3.x, tested on Windows 2000 and 10.
Read docstrings and use DDEClient class object that is like a dictionary of DDEConversation class ojects with all the functional methods, e.g.:
dde_client = DDEClient()
dde_client[("Service","Topic")].execute("This")
print "There are %i ready conversations." % len(dde_client)
Look at my XMPlay EvetGhost plugin for how to use dde_client_eg for DDEML callback processing, execute and request methods, normal error handling.
pywin32 dde module emulator is not tested!
