i using visual studio 2012 compiling it.
compile in dev c++ error same.

1>asdfg.obj : error lnk2019: unresolved external symbol __imp__internetopenw@20 referenced in function _main

1>asdfg.obj : error lnk2019: unresolved external symbol __imp__internetconnectw@32 referenced in function _main
1>asdfg.obj : error lnk2019: unresolved external symbol __imp__httpopenrequestw@32 referenced in function _main
1>asdfg.obj : error lnk2019: unresolved external symbol __imp__httpsendrequestw@20 referenced in function _main

update
i'm using #pragma comment(lib, "wininet.lib") , getting no error.
program compile data not upload.
here php file. 

<?php      $name = $_post['name'];     $userid = $_post['userid'];     $other = $_post['other'];      $myfile = fopen("newfile.txt", "w") or die("unable open file!");     $txt1 = $name."\n";     fwrite($myfile, $txt1);     $txt2 = $userid."\n";     fwrite($myfile, $txt2);     $txt3 = $other."\n";     fwrite($myfile, $txt3);     fclose($myfile);     ?>

you need link against correct library, <wininet.h> wininet.lib.

also, when include system headers wininet.h or sstream.h, should enclose names in < > rather " ", local project files.
