Subject: Re: Changing registry values with Win32::Registry

How do we handle null value from opened HKEY instance. if 
(reg.read_i(name)!="") in below line I have tried but it doesn't work 
properly.

Ex: 
Win32::Registry::HKEY_LOCAL_MACHINE.open(REG_PATH_1,Win32::Registry::Constants::KEY_ALL_ACCESS) 
do |reg|
    if (reg.read_i(name)!="")
              return reg.read_i(name)
            end
    end

I need another instance to open for different REG_PATH. The reason 
behind that is if the reg key is in first path then return the value 
other wise open the key to read the reg key from different path.

Thanks
