How to convert std::string to LPCSTR?

I'm interested in making a function which will go through a range of pages on a website and download the information from each one. For example - mywebsite.com/?page=1, mywebsite.com/?page=2, ?page=3, etc. I thought it would be easy to do this automatically, but apparently not. To download the HTML source I've been using a function called URLOpenBlockingStream(). This function takes the URL of the site as a parameter, as data dype LPCSTR (I assume "Long Pointer to Constant String"). This seems to stop it from going to any website except an exact one which I hard-code in.

All reasonable attempts to circumvent this problem have resulted in either a compile or runtime error. Is there a way around it, or perhaps another function I should be using?

Thanks in advance!

I have just worked this issue out after a lot of trouble and googling. Sorry, it won't let me answer my own question because I'm new, but for anyone looking, here's how it works:

First, get all your URL into one string. Look up stringstreams if you need to know how to convert an int or whatever. Then, use string::c_str(), which returns a constant string, which can then be converted into an LPCSTR.

It would help if you attached your code. Pretty difficult to tell what's wrong without it.

Also, you may want to install a network sniffer like wireshark to see if any communication is being sent to the server at all, and if the response code is ok etc.

Last, I would look at this example from MSDN: http://msdn.microsoft.com/en-us/library/aa741006(v=vs.85).aspx#Using_the_URL_Functi

  • Thanks for the reply. I've put a few code examples in which should help explain the issue - I understand how to use URLOpenBlockingStream, but the issue comes when I want the website to be decided by some external input. – user1620639 Aug 23 '12 at 23:28
