DDEDATA

The DDEDATA structure contains the data, and information about the data, sent as part of a WM_DDE_DATA message. This structure supersedes the DDEUP structure.

typedef struct { // ddedat

unsigned short unused:12,

fResponse:1,

fRelease:1,

reserved:1,

fAckReq:1;

short cfFormat;

BYTE Value[1];

} DDEDATA;

Members

fResponse

Indicates whether the data was sent in response to a WM_DDE_REQUEST message or a WM_DDE_ADVISE message. If this value is nonzero, the data was sent in response to a WM_DDE_REQUEST message.

fRelease

Indicates whether the application receiving the WM_DDE_POKE message should free the data. If this value is nonzero, the application should free the data.

fAckReq

Indicates whether the application receiving the WM_DDE_DATA message should acknowledge receipt of the data by sending a WM_DDE_ACK message. If this value is nonzero, the application should send the acknowledgment.
