## Method Details

### onWildconnect

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!)
