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.
