Hello, once again



I have a very BIG problem. I made program that connect to proxy server and browse via proxy server. However, my company has a made private proxy server which I must authenticate through to get to the internet.



I read hundreds pages of docs, but without success. My program code look like so:

    module:

Public Declare Sub UrlMkSetSessionOption Lib "urlmon.dll" _

(ByVal dwOption As Long, ByRef pBuffer As Any, _

ByVal dwBufferLength As Long, ByVal dwReserved As Long)



Public Type INTERNET_PROXY_INFO

dwAccessType As Long

lpszProxy As String

lpszProxyBypass As String

End Type

Public Const INTERNET_OPEN_TYPE_PROXY = 3

Public Const INTERNET_OPTION_PROXY = 38



Public Declare Function InternetSetOption Lib "wininet.dll" Alias "InternetSetOptionA" _

(ByVal hInternet As Long, ByVal lOption As Long, ByRef sBuffer As Any, ByVal lBufferLength As Long) As Integer

Public Declare Function InternetSetOptionStr Lib "wininet.dll" Alias "InternetSetOptionA" _

(ByVal hInternet As Long, ByVal lOption As Long, ByVal sBuffer As String, ByVal lBufferLength As Long) As Integer





form:

Private Sub Command6_Click()

Dim ipi As INTERNET_PROXY_INFO

dim username as string

dim password as string



ipi.dwAccessType = INTERNET_OPEN_TYPE_PROXY

ipi.lpszProxy = "46.37.165.113:17890"

ipi.lpszProxyBypass = ""



username = "america01" 'proxy server ID and PASS real and WORKING

password = "YpEEJy8u" 'proxy server ID and PASS real and WORKING



call UrlMkSetSessionOption(INTERNET_OPTION_PROXY_USERNAME, username, sizeof(username), 0);

call UrlMkSetSessionOption(INTERNET_OPTION_PROXY_PASSWORD, password, sizeof(password), 0);

call UrlMkSetSessionOption(INTERNET_OPTION_PROXY, ipi, Len(ipi), 0)

Form1.WebBrowser1.Navigate "http://whatismyipaddress.com/"





What wrong I`m doing ?

Are you getting any errors? In your code, is sizeof a function? Does replacing sizeof with Len make a difference?
