Personal Communications Response

Personal Communications receives the Start Close Intercept and returns an ACK message if it can start the intercept. Otherwise a negative ACK message is returned to the client with one of the following return codes in the low-order byte of the wStatus field:

WM_DDE_ACK(wStatus, aCLOSE)

Once the intercept starts, the client receives DATA messages notifying it that the close request is intercepted:

WM_DDE_DATA(hData, aCLOSE)

where:

hData

Identifies a handle to a Windows global memory object containing:

typedef struct tagCLOSEREQ
{
  unsigned char  data[(sizeof(DDEDATA)-1)];
  unsigned short uCloseReqCount; /* Number of the close requests.
} CLOSEREQ;
 
typedef union tagDDE_CLOSEREQ
{
  DDEDATA   DDEdata;
  CLOSEREQ  DDEclose;
} DDE_CLOSEREQ, *lpDDE_CLOSEREQ;
