    - #### onConnect

          boolean onConnect(int transactionType,
                            Ddeml.HSZ topic,
                            Ddeml.HSZ service,
                            Ddeml.CONVCONTEXT convcontext,
                            boolean sameInstance)

      A client uses the XTYP_CONNECT transaction to establish a conversation. A Dynamic Data Exchange (DDE) server callback function, DdeCallback, receives this transaction when a client specifies a service name that the server supports (and a topic name that is not NULL) in a call to the DdeConnect function.
      Parameters:
        `transactionType` - uType - The transaction type.
        `topic` - hsz1 - A handle to the topic name.
        `service` - hsz2 - A handle to the service name.
        `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:
        true is connect can continue
