IE Security Zones

Hi,

I need to check whether Javascript and Cookies are enabled on Internet Explorer browser or not. So, I am checking IE security zones as mentioned in the following URL(checking the values in Zones -3) from .net code.

I am checking the values of following registry keys under "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3" registry from .net.

1400     Scripting: Active scripting
1A02     Allow persistent cookies that are stored on your computer #

I want to know whether it is right approach or not.

Please help me.
