Загрузка страницы с использованием прокси через WinInet API

Оч нужно загрузить страницу используя прокси. Использую для этого код:

[code]

Public Const INTERNET_OPEN_TYPE_PRECONFIG = 0

Public Const INTERNET_OPEN_TYPE_DIRECT = 1

Public Const INTERNET_OPEN_TYPE_PROXY = 3

Public Const INTERNET_DEFAULT_HTTP_PORT = 80

Public Const INTERNET_DEFAULT_HTTPS_PORT = 443

Public Const INTERNET_SERVICE_HTTP = 3

Public Const INTERNET_FLAG_RELOAD = &H80000000

Public Const INTERNET_FLAG_SECURE = &H800000

Public Const INTERNET_FLAG_KEEP_CONNECTION = &H400000

Public Const INTERNET_FLAG_NO_AUTH = &H40000

Public Const INTERNET_FLAG_FORMS_SUBMIT = &H40

Public Const INTERNET_OPTION_PROXY = 38

Public Const INTERNET_OPTION_SETTINGS_CHANGED As Long = 39

Public Const INTERNET_FLAG_ASYNC = &H10000000

Public Const INTERNET_FLAG_OFFLINE = &H1000000

Ответ на VBA есть.
Но нужен ли еще он ввиду давности темы
