This sample demonstrates a way to author a real-time data-feed as a high-performance C++ Excel add-in.

The application uses Excel’s RTD (Real-Time Data) protocol, and demonstrates the following features:

  • Real-time data functions that return arrays as well as scalars.
  • Enhanced user interface for the Excel Formula Wizard, including drop-down lists for enumerated values, such as field identifiers, and a pop-up dialog for locating a security code.
  • Controls for managing the performance of the feed.
