Description

Opens a windows registry key. Static

Syntax

Regkey.open(keyname)

keyname

Specifies the key name of the registry. If keyname begins with a predefined key, it defines an absolute key name. The predefined key names are:

HKCC	HKEY_CURRENT_CONFIG
HKCU	HKEY_CURRENT_USER

Otherwise, keyname defines a sub key of Regkey.

Returns

If the registry key specified by the keyname parameter has been successfully opened, a new instance of the RegKey object is created. Otherwise, returns null.

Example

r = RegKey.open("HKCU\\Software\\Demo1");
sub = r.open("subkey");
sub2 = RegKey.open("subkey");
//returns null because "subkey" has no root.
