C ++ 307 Ошибки при попытке включить winhttp.h в Visual Studio 2010

У меня большая проблема. Я пытаюсь использовать WinHttp для загрузки файла с C ++, и я использую Visual Studio 2010 для этого.

Моя проблема в том, что программа не компилируется, потому что генерируются 307 ошибок, все из которых относятся к winhttp.h . Я упоминаю, что я включил этот файл. В чем может быть проблема? Спасибо!

Теперь у меня другая проблема. Это мой код:

#include <windows.h>
#include <winhttp.h>
#include <stdio.h>
#include <iostream>
using namespace std;
#include <string.h>

int main()

    DWORD dwDownloaded = 0;
    LPBYTE pszOutBuffer;
    BOOL bResults = FALSE;
    HINTERNET hSession = NULL, hConnect = NULL, hRequest = NULL;

// Use WinHttpOpen to obtain a session handle.
hSession = WinHttpOpen( L"Internet Explorer example", 
    WINHTTP_ACCESS_TYPE_DEFAULT_PROXY,
    WINHTTP_NO_PROXY_NAME, 
    WINHTTP_NO_PROXY_BYPASS, 0 );

// Specify an HTTP server.
if( hSession )
    hConnect = WinHttpConnect( hSession, L"www.my-new-gadget.com",
    INTERNET_DEFAULT_HTTPS_PORT, 0 );

// Create an HTTP request handle.
if( hConnect )
    hRequest = WinHttpOpenRequest( hConnect, L"GET", L"index.php",
    NULL, WINHTTP_NO_REFERER, 
    NULL, NULL);

// Send a request.
if( hRequest )
    bResults = WinHttpSendRequest( hRequest,
    WINHTTP_NO_ADDITIONAL_HEADERS, 0,

        }        
        else        
        {            
            // Read the Data.            
            ZeroMemory(pszOutBuffer, dwSize+1);            
            if (!WinHttpReadData( hRequest, (LPVOID)pszOutBuffer, dwSize, &dwDownloaded))                
            {

                DWORD wmWritten;
                bool fr = WriteFile(hFile, pszOutBuffer, dwSize, &wmWritten, NULL);
                int n = GetLastError();              
            }            
            // Free the memory allocated to the buffer.            
            delete [] pszOutBuffer;        
        }    
    } while (dwSize>0);
}

CloseHandle(hFile);
// Report any errors.

В чем может быть проблема? 2 дня пытаюсь сделать кусок программы для скачивания файла по заданному URL. Это сводит меня с ума! Пожалуйста, помогите мне!
