Why do registry changes only happen once?

Question

C++ / C#

There is a code:

RegistryKey myKey = Registry.CurrentUser;
RegistryKey wKey = myKey.CreateSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings", true);
wKey.SetValue("ProxyServer", proxyhost + ":" + port.ToString());
wKey.SetValue("ProxyEnable", 1);
wKey.Close();
myKey.Close();

it's tied to a mouse click, and what it does is change the system proxy in the browser's properties. So this code works for some reason only once when you start the program, if you select another proxy, then it will not change. If you restart the program and select a proxy, the code will work. Why is this happening and how to fix it?

Answer 1

Try manually flushing:

RegistryKey wKey = ...
wKey.SetValue(...);
wKey.Flush();
wKey.Close();
