Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

WM_DDE_ACK
mp1 = MPFROMHWND(hwnd);    /* sender's window                */
mp2 = MPFROMP(pdde);       /* pointer to DDESTRUCT structure */
 
The WM_DDE_ACK 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. The
acknowledging application modifies the fsStatus field of the DDESTRUCT
structure to return information about the status of the message received.
