onWildconnect

java.util.List<Ddeml.HSZPAIR> onWildconnect(int transactionType,
                                            Ddeml.HSZ topic,
                                            Ddeml.HSZ service,
                                            Ddeml.CONVCONTEXT convcontext,
                                            boolean sameInstance)

Enables a client to establish a conversation on each of the server's service name and topic name pairs that match the specified service name and topic name. A Dynamic Data Exchange (DDE) server callback function, DdeCallback, receives this transaction when a client specifies a NULL service name, a NULL topic name, or both in a call to the DdeConnect or DdeConnectList function.

Parameters:

transactionType - uType - The transaction type.

topic - A handle to the topic name. If this parameter is NULL, the client is requesting a conversation on all topic names that the server supports.

service - A handle to the service name. If this parameter is NULL, the client is requesting a conversation on all service names that the server supports.

convcontext - dwData1 - CONVCONTEXT structure that contains context information for the conversation. If the client is not a DDEML application, this parameter is NULL.

sameInstance - dwData2 - Specifies whether the client is the same application instance as the server.

Returns:

the supported HSZPAIRs (do not include the terminating pair needed be the DdeCallback!)
