## Method Details

### 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
