Streaming website data into Excel with VBA

Question

A website provides streaming stock quotes via a browser over HTTPS connection. This is done by the server sending a POST HTTP header and updating its body with the new quotes. The DOM is then updated and this then translates into visual updates. I want to get these quotes, preferrably streaming as well, into Excel. I may use only VBA, .NET framwork, and firefox add-ons.

I am stuck over how to do it. I am limited to VBA and .NET and Firefox add-ons. What libraries, objects, firefox add-ons would you advise me to use?

Answer 1

You don't need FireFox. You can either query data from VBA (good example is on Mr Excel forum) or .NET (another set of examples on Wilmott forum). To refresh the data you can use Excel timer (Application.OnTime) or have infinitive loop. If you would like to refresh a number of cells independently, you may want to utilise RDT function which is very useful in such case (MS Excel Help).
