XTYP_ADVDATA
XTYP_ADVDATA
A dynamic
data exchange (DDE) client callback function receives the XTYP_ADVDATA
transaction after establishing an advise loop with a server. This transaction
informs the client that the value of the data item has changed.
Parameters
uFmt
Specifies the
format atom of the data sent from the server.
hconv
Identifies
the conversation.
hsz1
Identifies
the topic name.
hsz2
Identifies
the item name.
hdata
Identifies
the data associated with the topic name and item name pair. This parameter is NULL
if the client specified the XTYPF_NODATA flag when it requested the advise
loop.
dwData1
Not used.
dwData2
Not used.
Return Values
A DDE
callback function should return DDE_FACK if it processes this transaction,
DDE_FBUSY if it is too busy to process this transaction, or DDE_FNOTPROCESSED
if it rejects this transaction.
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.
