DDE Client Bridge Advanced Features Include

  • DDE Link can be reinitialized via built-in Reintialization tag.
  • String array support for XLTable format type
  • This driver uses "hot links", where a DDE server passes data to the driver only when the data value has changed. (This provides a significant performance advantage over the alternative request/response loop approach, since each DDE transaction is relatively time consuming.)
  • This driver will automatically reconnect when DDE servers are brought back on-line.
  • Clients may reside on remote machines and communicate with this driver via OPC or NetDDE. (Note: The current version of this driver cannot access data from DDE servers running on remote machines.)
