Read windows registry Key values

Hi All,

I am working on a use case where I need to read two registry key values and
compare there data in a recipe

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ActiveComputerName

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName

both are having a value name(ComputerName) and value data(may be same or
different). I need to compare there value data.

Do I need to write like this:; or some other better way??

Win32::Registry::HKEY_LOCAL_MACHINE.open(keynameComp, access) do |reg|
reg.each{|name, value, keys | compName = keys}
end
Win32::Registry::HKEY_LOCAL_MACHINE.open(keynameActive, access) do |reg|
reg.each{|name, value, keys | compNameActive = keys}
end

Any idea??

Thanks & Regards,
Sachin Gupta

Sachin, have you looked at the docs for the registry_key resource:
https://docs.chef.io/resource_registry_key.html,
http://docs.chef.io/release/12-0/dsl_recipe.html#registry-get-values ?

The registry_key_get_values? DSL element seems like a good place to start,
the docs should have examples that clarify the usage.

Thanks Adam for the useful links.

I am trying to execute this code from a recipe to get the values of registry

require 'win32/registry'

keynameComp=
"SYSTEM\CurrentControlSet\Control\computername\computername"
keynameActive=
"SYSTEM\CurrentControlSet\Control\computername\activecomputername"
compName = ""
compNameActive = ""
access =Win32::Registry::KEY_ALL_ACCESS

Win32::Registry::HKEY_LOCAL_MACHINE.open(keynameComp, KEY_READ) do |reg|
reg.each{|name, value, keys | compName = keys}
end

::Win32::Registry::HKEY_LOCAL_MACHINE.open(keynameActive, KEY_READ) do |reg|
reg.each{|name, value, keys | compNameActive = keys}
end

I am getting error messages as "[2015-03-02T09:52:32+00:00] FATAL:
NameError: uninitialized constant Chef::Win32::Registry::KEY_ALL_ACCESS"

Would like to know, do I need to include any other gem?

Thanks & Regards,
