      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
