LastKey in Registry

Hey.. I'm trying to make a lastkey thing for the registry editor so that it will open right to a specific key.. here's hwat I have so far.. but it wont work. I get an 'object reference not set to an instance of an object' error.

VB Code:

Dim test As RegistryKey
            test= Registry.CurrentUser.OpenSubKey("\\Software\\Microsoft\\Windows\\CurrentVersion\\Applets\\Regedit\\", True)
            test.SetValue("lastkey", "Test")
            Shell("regedit")

Why are you trying to escape your backslashes? You don't do that in VB.NET, so it may well be interpreting the double backslashes as a subkey of a key with no name, which would always return Nothing. Also, I don't think you need to start the string with a backslash either.
