Methods
| ConnectData(Int32, Array, Boolean) |

| DisconnectData(Int32) |
Notifies a real-time data (RTD) server application that a topic is no longer in use. |
| Heartbeat() |
Determines if the real-time data server is still active. Zero or a negative number indicates failure; a positive number indicates that the server is active. |
| RefreshData(Int32) |
This method is called by Microsoft Excel to get new data. |
| ServerStart(IRTDUpdateEvent) |
The ServerStart method is called immediately after a real-time data server is instantiated. Negative value or zero indicates failure to start the server; positive value indicates success. |
| ServerTerminate() |
Terminates the connection to the real-time data server. |
