I am trying to make my console application fetch stock quotes from yahoo finance so I can do calculations with that data. I have been looking on the internet been have not been able to find anything out there. Does anyone have any suggestions for me.
Thanks,
Pete
have you read this: http://developer.yahoo.com/finance/ ?

your yahoo link talks about c#... Thanks for the link though

this website has all the stuff needed to get quote data via internet explorer. What I would like to do is have my program call internet explorer so to speak use the url with stock symbol to retrieve the data I need and put it into a variable in my program.. Hope that makes things a little more clear.

so why not to open the socket, send the http request as described and parse the response?

How do you "why not to open the socket"? I would like to try and write a program like that myself.
look up WinSock
I've gotten that far before. Is there a good "hello world" winsock tutorial anywhere?
I am just learning C++ I am in my second semester of C++ so it is a challenge still.. Thanks for the response I will look up opening a socket to see if this will get me where I need to go.
Thanks,

HTTP in raw sockets is perhaps not such a good idea. But there are various free HTTP libraries out there, for example cURL or the W3C's libwww.
All the buzzt!

still haven't been able to have my program connect to yahoo finance.. Any other ideas?
- post your code
- post your analysis of the problem
-- does it compile - if not, what error messages
-- does it run
-- does it crash - if it does, what error messages
-- does it connect - if not, what error messages
-- does it fetch any data at all - is it correctly formatted or junk
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
okay found a tutorial on winsock but stuck on the above code. I assume this is where I request the information from ther server.. Below is an example of getting the stock quote in the browser..Code:const char HEAD_REQUEST_PART1[] = { "HEAD / HTTP/1.1\r\n" // Get root index from server "Host: " // Specify host name used }; const char HEAD_REQUEST_PART2[] = { "\r\n" // End hostname header from part1 "User-agent: HeadReqSample\r\n" // Specify user agent "Connection: close\r\n" // Close connection after response "\r\n" // Empty line indicating end of request };

but how do I incorporate this into the header request? I assume that is where I put the information I want.. Looked for info on HTTP protocol but I don't believe I found anything that helped...
Thanks,
Pete
