Where to look for API win32/registry

ruby-talk
1

Hi!

I am trying to write a small script that cleans up the registry after starting Skype (which on regular basis registers itself in Run).

What I am looking now is the API of Win32::Registry. Where can I find it?

So far I have done this:

require 'win32/registry'
Run_branch = 'Software\Microsoft\Windows\CurrentVersion\Run'
Skype_key = 'Skype'
Win32::Registry::HKEY_CURRENT_USER.open(Run_branch, Win32::Registry::Constants::KEY_ALL_ACCESS) do |

reg |

  reg_typ, reg_val = reg.read(Skype_key)
  puts "type: #{reg_typ}"
  puts "val : #{reg_val}"
end

type: 1
val : "C:\Program Files\Skype\Phone\Skype.exe" /nosplash /minimized

As you can see I was able to identify the key, but I don't know what can I do next. Win32::Registry doesn't seem to have a method to delete or modify the content of the key.

On a more general note usually when you want to use such an extension where should I look for documentation?

thanks a lot,

./alex

If you haven't built, or don't have an install of, the rdoc
documentation for Ruby, you can find it at
http://www.ruby-doc.org/stdlib/

Modifying and deleting is fairly easy, IIRC:

reg[Skype_key] = "new value"
reg.delete_key(Skype_key)

delete_key results in error:

Win32::Registry::Error: The system cannot find the file specified.
         from c:/ruby/ruby-1.8.2-15/lib/ruby/1.8/win32/registry.rb:800:in `delete_key'

The first 260 lines of registry.rb is an rdoc description
although I couldn't find an entry on ruby-doc.
Readable enough though.

delete_key results in error:

You want delete_value(Skype_key) # (alias delete)

Your key is 'Run' ... 'Run' can have multiple values ...
.... each value can have data associated with it.

So, one 'Run' value is 'Skype' which has data of "C:\...Skype.exe...".

Whatever; I call 'Skype' a key and the data its value because
'[key] = value' fits better than '[value] = data', in my head.

Yep, usually I am using the same terms, but it seems once again that
MS is smarter :-).
