WM DDE ACK

This message notifies an application of the receipt and processing of a WM_DDE_EXECUTE, WM_DDE_DATA, WM_DDE_ADVISE, WM_DDE_UNADVISE or WM_DDE_POKE message, and in some cases, of a WM_DDE_REQUEST message.

This message is always posted.

Syntax

param1
HWND hwnd;          /* Window handle of the sender. */

param2
PDDESTRUCT pDdeStruct; /* DDE structure. */

Parameters

hwnd (HWND) - input

Window handle of the sender.

pDdeStruct (PDDESTRUCT) - input

DDE structure.

This points to a dynamic data exchange structure. See DDESTRUCT.

The acknowledging application modifies the fsStatus field to return

information about the status of the message received:

DDE_FACK

1 = request accepted

0 = request not accepted

DDE_FBUSY

1 = busy

0 = not busy

DDE_NOTPROCESSED: Reserved for application-specific return codes

DDE_FAPPSTATUS: The message was not understood and was ignored.

An application is expected to set DDE_FBUSY if it is unable to respond to the

request at the time it is received. The DDE_FBUSY flag is defined only when DDE_

FACK is 0.

offszItemName identifies the item for which the acknowledgment is being sent.

Returns

ulReserved (ULONG) - return

Reserved value, should be 0.

Default Processing

None.
