RegDeleteKey - Delete a Registry Key

Valid on Windows

The RegDeleteKey function removes the specified key.

This registry manipulation function has the format:

RegDeleteKey(hKey as Integer, subkey as String) as Boolean

hKey

Indicates a currently open key or a predefined key and can be any of the following predefined values, which are available on all Windows platforms:

HKEY_CLASSES_ROOT

HKEY_CURRENT_USER

HKEY_LOCAL_MACHINE

HKEY_USERS

subkey

Indicates the parameter is a string that specifies the name of the key to delete. Subkey must be a subkey of the key identified by hKey. Do not use an empty string as a subkey parameter.

On successful completion, the function returns TRUE. If the key does not exist or is currently opened by another application, it returns FALSE.

subkeys

On Windows 9x, this function also removes all subkeys. On Windows NT and 2000, you must remove each subkey separately before running the function.
