Checks registry key for existing.
const ARoot: HKey;
const AKey: String
One of predefined HKEY_XYZ constants. Usually it's HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE.
A full absolute path to key.
True, if specified key exists (i.e. you have a minimum a read access), False - otherwise.
This is low-level routine. Use it only to implement your own custom high-level wrapper.
Use ConfigReadString or ConfigWriteString (or their equivalents) to read and write configurations.
