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.
