How do i discover SQL server is running ...

Hello ,

I'm trying to create an application, which would say if sql server is
running on a machine.

Hope i can get this from windows registry. Is there any other way do
achieve this programatically through windows SDK , or checking the
services programatically ?
If i need to check the registry what are the fields that i should look
at ?

thanks in advance,
Velu
