以编程方式更改Internet Explorer代理（包括密码）而无需重新启动，即在vb.net中

Question

Is it even possible?

I know a way to do so is to change the registry. However there has to be a better way.

Shared Sub EnableProxy1()

Dim regKey As Microsoft.Win32.RegistryKey

regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Internet Settings", True)
regKey.SetValue("ProxyEnable", True, Microsoft.Win32.RegistryValueKind.DWord)
regKey.SetValue("ProxyServer", proxyhandler.proxyFedtoInternetExplorer, Microsoft.Win32.RegistryValueKind.String)
regKey.SetValue("ProxyOverride", "<local>", Microsoft.Win32.RegistryValueKind.String)
regKey.Close()

End Sub

Shared Sub DisableProxy() Dim regKey As Microsoft.Win32.RegistryKey

regKey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\Microsoft\Windows\CurrentVersion\Internet Settings", True)

regKey.SetValue("ProxyEnable", False, Microsoft.Win32.RegistryValueKind.DWord)

regKey.Close()

End Sub

Doing this has 2 weaknesses

1. I need to restart internet explorer
2. I need to change the username and password of the proxy by manipulating windows directly.

I want a method that's better and direct. Any ways?
