I have a created a custom context menu on right click of any file/folder - "Universal Send to" as part of main context menu in the registry using Microsoft.Win32 class in C#.
The sub menu items to this menu are the names of PC's in the network and I've coded such that they get added dynamically whenever a device is detected in the network.
I have added a property 'IP address' to its sub context menu item in the registry. I have a single executable (-FileTransfer.exe) for all the context items (like HomePC, OfficePC, etc..), that transfers the file/folder to the selected PC.
However, I am not able to make it work for dynamic Pc's as I am not able to fetch the IP address for the selected device and pass the same as a parameter to the executable.

C# Code snippet: (Hardcoded HomePC in registry now for test purpose):

RegistryKey key;
            key = Registry.ClassesRoot.CreateSubKey(@"*\shell\UniSendTo");
            string MUIVerb = "Universal Send To";
            string ExtendedSubCommandsKey = @"*\shell\UniSendTo\MainMenu";         
            key.SetValue("MUIVerb", MUIVerb);
            key.SetValue("ExtendedSubCommandsKey", ExtendedSubCommandsKey);
            RegistryKey  key1 = Registry.ClassesRoot.CreateSubKey(@"*\shell\UniSendTo\MainMenu");
            key1 = Registry.ClassesRoot.CreateSubKey(@"*\shell\UniSendTo\MainMenu\shell");
            RegistryKey  key2 = Registry.ClassesRoot.CreateSubKey(@"*\shell\UniSendTo\MainMenu\shell\HomePC");
            string MUIVerb1 = "Home PC";
            key2.SetValue("MUIVerb",MUIVerb1);
            string ip = "192.168.1.22";
            key2.SetValue("IP",ip);
            RegistryKey key3 = Registry.ClassesRoot.CreateSubKey(@"*\shell\UniSendTo\MainMenu\shell\HomePC\command");
            key3.SetValue("",@"H:\ERT\FileTransfer.exe");
