Checking for Registry Entries
Is it possible to check if a Registry entry exists (i.e. HKLM/Software/abc...)

If so, how?

The error flag will be set if it doesn't exist.

ok, that works for a specific registry key. any way to check for a registry folder? no key...

HKLM/Software/Abc/xyz/

as opposed,

"HKLM/Software/Abc/xyz/123"

"root_key" "sub_key" "name"

b/c if I leave the name empty it wont work.
