The DDEACK structure contains status flags that a DDE application passes to its partner as part of the WM_DDE_ACK message. The flags provide details about the application's response to a WM_DDE_ADVISE, WM_DDE_DATA, WM_DDE_EXECUTE, WM_DDE_REQUEST, WM_DDE_POKE, or WM_DDE_UNADVISE message.
bAppReturnCode
Specifies an application-defined return code.
fBusy
Indicates whether the application was busy and unable to respond to the partner's message at the time the message was received. A nonzero value indicates the server was busy and unable to respond. The fBusy member is defined only when the fAck member is zero.
fAck
Indicates whether the application accepted the message from its partner. A nonzero value indicates the server accepted the message.
