Solve : Check for registry key c++?

1.	Solve : Check for registry key c++?
Answer» How do I check the (Default) REGISTRY entry in c++ and return TRUE, if exists, and false, if not.Earlier, I SAID I wanted to check if it existed or not. I meant to check if it is empty. I tried using the RegQueryValueEx function, but when I put NULL for the second param (which should supposedly READ the (Default) entry) it always gives me NULL for the entry even if there is something in it. So how do I read (Default) VALUE and determine if it is empty?
