    #  Retrieve a value from the Registry
    def get_registry_sync
        theRegSetting = Rho::System.getRegistrySetting({hive:'HKLM', key:'software', Setting:'RhoElementsTest'})
        puts "Registry Setting retrieved: #{theRegSetting}"
    end
    
    #  Set a value in the registry which will persist across a clean boot of the device
    def set_registry_sync
        theRegSetting = Rho::System.setRegistrySetting({hive:'HKLM', type:'String', key:'Software', setting:'RhoElementsTest', value:'MVC ftw', persistent:true})
        puts "Registry Setting Success?: #{theRegSetting}"
    end
    
    #  Delete a value from the registry
    def delete_registry_sync
        theRegSetting = Rho::System.deleteRegistrySetting({hive:'HKLM', key:'Software', setting:'RhoElementsTest', persistent:true})
        puts "Registry Deleting Success?: #{theRegSetting}"
    end
