Using C++ to stream data

[JudyFaye]

Hello all

I am trying to build a C++ program to get data from any kinda stocks and shares website and then tinker around with that data. Put on graphs, averages that stuff. It's mainly the streaming from web part that's bogged me down. I'm hearing a lot on http libraries and things like that and some 3rd party libraries.

Any help specific to this would be appreciated

Generally if I'm in need of a HTTP library, libCurl (http://curl.haxx.se/) is my first port of call.

That might be because it's the wrong way to do this. RSS has been around since the 90's and it's survived this long for a reason. Pulling a text file that cached, indexed and is made publicly available for this exact purpose is a lot easier then digging through the dynamically generated code presented to the browser for the users interface.

Ye I've tried this site and I have very little idea exactly what to do. Any direction

Look at the examples.

For instance, this one: http://curl.haxx.se/libcurl/c/sepheaders.html
Change "http://example.com" to (say) "http://www.nasdaq.com/markets/", build and run it.

Or instead of grepping the kitchen sink you could use the tools provided by that same site to collate a custom URL to query: http://www.nasdaq.com/services/rss.aspx

Ultimately I guess it depends on what data you really want. JLBorges suggestion isn't wrong, it's just not targeted at any specific set of data.
