I’ve been doing a lot of Excel RTD addin coding recently, as I’ve been adding RTD support to SpreadServe. As part of that work I’ve developed two new addins, both of which I’ve posted on github. Of course, both addins work in Excel and SpreadServe. The first, SSAddin, supports quandl.com queries and Unix cron style timer events on background threads. Both these things can be done with VBA of course, and that’s how quandl’s existing Excel addin does it. However, SSAddin gives you the means to achieve automated, scheduled downloads from quandl with no Visual Basic and no manual keystrokes into a GUI. The second addin, kkaddin, is based on Kenny Kerr‘s example C# RTD code. While I was researching RTD I read Kenny’s excellent material on the topic. John Greenan also has some quality content on his blog too. However, I wasn’t able to find a single, simple, download with C# boilerplate code that would build and run; so that’s what kkaddin addresses.
