XTYP_XACT_COMPLETE
XTYP_XACT_COMPLETE
A dynamic
data exchange (DDE) client callback function receives the XTYP_XACT_COMPLETE
transaction when an asynchronous transaction, initiated by a call to the DdeClientTransaction function, has completed.
Parameters
uFmt
Specifies the
format of the data associated with the completed transaction (if applicable) or
NULL if no data was exchanged during the transaction.
hconv
Identifies
the conversation.
hsz1
Identifies
the topic name involved in the completed transaction.
hsz2
Identifies
the item name involved in the completed transaction.
hdata
Identifies
the data involved in the completed transaction, if applicable. If the
transaction was successful but involved no data, this parameter is TRUE. This
parameter is NULL if the transaction was unsuccessful.
dwData1
Specifies the
transaction identifier of the completed transaction.
dwData2
Specifies any
applicable DDE_ status flags in the low word. This parameter provides support
for applications dependent on DDE_APPSTATUS bits. It is recommended that
applications no longer use these bits future versions of the Dynamic Data Exchange Management Library
(DDEML) may not support them.
Remarks
An
application must not free the data handle obtained during this transaction. An
application must, however, copy the data associated with the data handle if the
application must process the data after the callback function returns. An
application can use the DdeGetData function to copy the data.
