DdeAbandonTransaction function (ddeml.h)
Abandons the specified asynchronous transaction and releases all resources associated with the transaction.
BOOL DdeAbandonTransaction(
[in] DWORD idInst,
[in] HCONV hConv,
[in] DWORD idTransaction
);
[in] idInst
Type: DWORD
The application instance identifier obtained by a previous call to the DdeInitialize function.
[in] hConv
Type: HCONV
A handle to the conversation in which the transaction was initiated. If this parameter is 0L, all transactions are abandoned (that is, the idTransaction parameter is ignored).
[in] idTransaction
Type: DWORD
The identifier of the transaction to be abandoned. If this parameter is 0L, all active transactions in the specified conversation are abandoned.
Type: BOOL
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
The DdeGetLastError function can be used to get the error code, which can be one of the following values:
Only a Dynamic Data Exchange (DDE) client application should call DdeAbandonTransaction. If the server application responds to the transaction after the client has called DdeAbandonTransaction, the system discards the transaction results. This function has no effect on synchronous transactions.
