| 3 | A wxDDEServer object represents the server part of a client-server DDE | |
| e2a6f233 JS |
4 | (Dynamic Data Exchange) conversation. |
| 5 | ||
| 6 | This DDE-based implementation is | |
| 7 | available on Windows only, but a platform-independent, socket-based version | |
| 8 | of this API is available using \helpref{wxTCPServer}{wxtcpserver}. | |

| 38 | Registers the server using the given service name. Under UNIX, the | |
| 39 | string must contain an integer id which is used as an Internet port | |
| cc81d32f | 40 | number. false is returned if the call failed (for example, the port |
| a660d684 KB |
41 | number is already in use). |

46 | |
| 47 | When a client calls {\bf MakeConnection}, the server receives the | |
| 48 | message and this member is called. The application should derive a | |
| 49 | member to intercept this message and return a connection object of | |
| 50 | either the standard wxDDEConnection type, or of a user-derived type. If the | |
| 51 | topic is ``STDIO'', the application may wish to refuse the connection. | |
| 52 | Under UNIX, when a server is created the OnAcceptConnection message is | |
| 53 | always sent for standard input and output, but in the context of DDE | |
| 54 | messages it doesn't make a lot of sense. | |
