Registry Keys

[Korupt]

Well I'm trying to create a registry reader and this is what I have so far:

            RegistryKey regkey = Registry.CurrentUser.OpenSubKey("Software\\Wow6432Nod\\VMware, Inc.\\VMware Workstation\\License.ws.6.0.200907");
            
            if (regkey.GetValue("CompanyName") != null)
            {
                string showIt = regkey.GetValue("CompanyName").ToString();
                MessageBox.Show(showIt);
            }

that however doesn't do anything, I'm just trying to read the company name form VMware Workstation, can anyone explain to me why my code doesn't work and how can I fix it? Thanks

I think it should be

RegistryKey regkey = Registry.CurrentUser.OpenSubKey("Software\\Wow6432Node\\VMware, Inc.\\VMware Workstation\\License.ws.6.0.200907");

Node the 'Wow6432Nod' becomes 'Wow6432Node'.

Check the path of the registry string : if it doesn't exist you won't get any results !

Also you should be doing this to ensure the key is closed when you've finished with it :

using (RegistryKey regkey = Registry.CurrentUser.OpenSubKey("Software\\Wow6432Node\\VMware, Inc.\\VMware Workstation\\License.ws.6.0.200907"))
{
    if (regkey.GetValue("CompanyName") != null)
    {
        string showIt = regkey.GetValue("CompanyName").ToString();
        MessageBox.Show(showIt);
    }
}

Try that, no need trying to reinvent the wheel.

Are yo stepping into the code in a debugger? If you don't know how to do this, please say so so we can explain how.

In answer to how to get the default value... Just pass in a "" to the GetValue() method.

Darwen, I developed a class to easily access the Registry, so I store the RegistryKey regkey as a member variable.
I am wondering:
How can I ensure the key is closed when I've finished with it, since I OpenSubKey in my constructor, then I GetValue in other functions (I cannot enclose it in a using case)?

Are you aware that ATL already has a registry class? It's called CRegKey. Just include <atlbase.h> to use it.
