Is it possible to use DDE in XP,instead of DDEML ?

[ToutEnMasm]

Hello,
I am making a DDE conversion between a client and a server and if i can use the DDEML , the DDE conversation seems to work only with WM_DDE_INITIATE and WM_DDE_ACK.
The fault come with GlobalAddAtom who returns only 32 bits values instead of 16 bits value.
I have used the samples in winhelp (#1234) but without success.
Is there a solution ?
