Proxy settings in Internet Explorer

[robinlovgren]

Hello,
not sure in what forum I would put this question.
I want to write a VB program that can controll which settings is checked in the LAN-settings window in internet explorer, to control what proxy-server will be used. I know about the proxyenable key in the registry, deciding if the proxy-server should be used or not, and also the key that decide what proxy will be used.
However, if I set proxyenable=0 (means to not use proxy), the setting for automatic detection is still checked in internet explorer, which means that it will still use a proxy-server. So to get around this, I must manually uncheck this. How can I do this in VB?

You would be better off posting this in the VB.NET forum really - PM a mod/admin and ask them to move it.

As for the question - I would assume that there is a registry value relating to the automatic detection of the proxy server as well so you would just modify that registry value accordingly. Have you looked to see if there is a corresponding registry value?

Here is some code from one of my older projects:
This changes the proxy settings to use a socks proxy running on port 8080:

'Enable Proxy

                ("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings", "ProxyServer", "socks=localhost:8080", Microsoft.Win32.RegistryValueKind.String)
