How can i download in c++ ?
Author
Hey guys :)
I start googling for this, but i cannot find the usefull words .. so i came here .
I wana let my program download an html / php file or whatever .
( for exemple , the index.html of a site ) . How can i do that ?
Thx .
look at the libcurl library. It provides a really easy interface for dealing with HTML/FTP/etc transfers through C++ code: http://curl.haxx.se/libcurl/.
The alternative is a different library or just using sockets programming. The latter isn't actually that bad, but there's a steep learning curve with sockets programming. it's useful to know but a little bit of a bitch to initially learn. But basically you just open up a send socket to the website in question and then send the properly formatted HTML GET/POST/etc string. You can google around for the HTML request formatting specifications.

Example:
#include <urlmon.h> //Must add the urlmon.h to project or URLDownloadToFile will not work.
#pragma comment(lib, "urlmon.lib") //Must add the lib file to project or URLDownloadToFile will not work.
int main()
{
HRESULT hr = URLDownloadToFile ( NULL, "http://www.cartoonlarry.com/index.htm", "C:\\cartoonlarry.htm", 0, NULL );
return 0;
}
Hope this helps :)

I believe you want to look into a library called WinSock.
libcurl >> Winsock =)
Winsock is the sockets programming stuff i mentioned in the latter of my 2 paragraphs.

Eheh, I thought the title said 'How can I download C++'.. Had one of those, 'oh-no, not another' moments [grin] Anyway, you probably want to look into sockets, or a higher level library/wrapper if you don't want to deal with the sockets directly.
For sockets, headers etc. can be used in a more crossplatform way using SDL_net, AFAIK. (I certainly use them in my projects, so that it can run on Win/Linux/Mac OSX/FreeBSD without having to enclose #include's in #ifdef's, etc.)
