Using proxies with a web browser. - r00t_z - Oct 17, 2014

Just thought I'd release this as it may come in handy to people.

This is not my code!

Code 
<Runtime.InteropServices.DllImport("wininet.dll", SetLastError:=True)> _

    Private Shared Function InternetSetOption(ByVal hInternet As IntPtr, ByVal dwOption As Integer, ByVal lpBuffer As IntPtr, ByVal lpdwBufferLength As Integer) As Boolean

    End Function

    Public Structure Struct_INTERNET_PROXY_INFO

        Public dwAccessType As Integer

        Public proxy As IntPtr

        Public proxyBypass As IntPtr

    End Structure

    Private Sub UseProxy(ByVal strProxy As String)

        Const INTERNET_OPTION_PROXY As Integer = 38

        Const INTERNET_OPEN_TYPE_PROXY As Integer = 3

        Dim struct_IPI As Struct_INTERNET_PROXY_INFO

        struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY

        struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy)

        struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local")

        Dim intptrStruct As IntPtr = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI))

        Marshal.StructureToPtr(struct_IPI, intptrStruct, True)

        Dim iReturn As Boolean = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, System.Runtime.InteropServices.Marshal.SizeOf(struct_IPI))

    End Sub

USAGE:

Code 
UseProxy("IP:PORT")

            WebBrowser1.Navigate("LINK")

Copy and pasting code and not giving credits is not good.
Please leave this section if this is all you are going to do.

Some people might actually find this handy.
No reason to hate as the OP said that this wasn't by him.

Anyways, thanks for sharing.

Exactly. Thank you for appreciating the share.

I found this on Google somewhere and couldn't find it on here, hence the reason I posted it.
