مشکل در پست فایل با استفاده از winhttp.h

سلام

من قصد ارسال فایل به یک صفحه aspx رو دارم

قطعه کد زیر رو دارم استفاده می کنم. اما در سمت مقصد، request بدون هیچگونه فایلی دریافت میشه(Request.Files.Count==0)

 int main()

{

    HINTERNET m_sessionHandle;

    wstring m_requestHost;



    m_sessionHandle = WinHttpOpen(L"my userAgent",

        WINHTTP_ACCESS_TYPE_DEFAULT_PROXY,

        WINHTTP_NO_PROXY_BYPASS,

        0);



    wstring m_requestURL = L"http://localhost/index.aspx?a=1";



    wchar_t szHostName[MAX_PATH] = L"";

    wchar_t szURLPath[MAX_PATH * 5] = L"";

    memset(&urlComp, 0, sizeof(urlComp));

    urlComp.dwStructSize = sizeof(urlComp);

    urlComp.lpszHostName = szHostName;

    urlComp.dwHostNameLength = MAX_PATH;

    urlComp.lpszUrlPath = szURLPath;

    urlComp.dwUrlPathLength = MAX_PATH * 5;

    urlComp.dwSchemeLength = 1; // None zero



    if (WinHttpCrackUrl(m_requestURL.c_str(), m_requestURL.size(), 0, &urlComp))

    {

        m_requestHost = szHostName;
