    - #### 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!)
