I am trying to correspond by means of a legacy 16-bit DDE server by writing an easy 16-bit DDE client using Borland Pascal with Windows. When I call the ddeInitialize purpose, I get a non-zero charge back, which I take for granted is a suitable instance handle. When I try to attach to the DDE server submission by passing a topic name but no service name, I get a non-zero discussion handle, but cannot do anything with it. If I identify the server name, the ddeConnect() function returns zero. DdeGetLastError() in addition returns zero.
