XTYP_DISCONNECT

XTYP_DISCONNECT 
 

An application's dynamic data exchange (DDE) callback function receives the XTYP_DISCONNECT transaction when the application's partner in a conversation uses the DdeDisconnect function to terminate the conversation.

Parameters

uFmt
Not used.
hconv
Handle to that the conversation was terminated.
hsz1
Not used.
hsz2
Not used.
hdata
Not used.
dwData1
Not used.
dwData2
Specifies whether the partners in the conversation are the same application instance. If this parameter is 1, the partners are the same instance. If this parameter is 0, the partners are different instances.

Remarks

This transaction is filtered if the application specified the CBF_SKIP_DISCONNECTS flag in the DdeInitialize function.

The application can obtain the status of the terminated conversation by calling the DdeQueryConvInfo function while processing this transaction. The conversation handle becomes invalid after the callback function returns.

An application cannot block this transaction type; the CBR_BLOCK return code is ignored.
