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.
