Registry Key save to a "Virtual Store" in current root and Local Machin, Help!

[Sl1ver]

I have this piece of code

 public bool Write(string KeyName, object Value)
        {
            try
            {
                // Setting
                string subKey1 = "SOFTWARE\\QwixAssets";
                RegistryKey rk = Registry.LocalMachine;
                RegistryKey sk1 = rk.CreateSubKey(subKey1);
                    //rk.CreateSubKey(subKey);
 
                // Save the value
                sk1.SetValue(KeyName.ToUpper(), Value);
 
                return true;
            }
            catch (Exception e)
            {
 
 
                MessageBox.Show(e.ToString(), "Writing registry " + KeyName.ToUpper().ToString());
                return false;
            }
        }
 

that used to work but for some reason it writes to current root - virtual store - machine and then the node but it also reads from there and my code for reading(when app starts up) is

public string GetRegistryValue(string KeyName)
        {
            // Opening the registry key
            string subKey = "SOFTWARE\\QwixAssets";
            RegistryKey rk = Registry.LocalMachine;
            RegistryKey sk = rk.OpenSubKey(subKey);
 
            if (sk == null)
            {
                MessageBox.Show("Problem in the Registry Source");
                return null;
            }
            else
            {
                try
                {
                    return (string)sk.GetValue(KeyName.ToUpper().ToString());
                }
                catch (Exception e)
                {
                    MessageBox.Show(e.ToString(), "Reading registry " + KeyName.ToUpper().ToString());
                    return null;
                }
            }
        }
 

Is this a windows 7 thing or is the code just wrong?

How can I get this working in C# Mobile Windows?
Suppose some "using" is needed?
What makes the the registry virtual, and how do you sore it in the real registry?

Thanks in advance for any help

AKJo, i haven't programmed much on windows mobile but this code will read and write to the real registry, i just got a way of saving it on the virtual store, try this code in a project and you will see it will write and read from the registry.

Obviously you will need to massage the code a little bit

[AKJo]

Tkanks for your advice, but my main, or at least first problem is that namespece name "RegistryKey" is not recognised by my compiler.
So obviously I miss a reference to it, but I don't know how to find out what I'm missing.

use...using Microsoft.Win32;
