Hope this is what you are searching for:
Add a single command button (Command1), and two control arrays -- a single text box with its Index property set to 0 (Text1(0)), and a single label with its index property set to 0 (Label1(0)). The Load event creates the required controls for the demo. Add the following code:
Option Explicit
Private Const VER_PLATFORM_WIN32_WINDOWS As Long = 1
Private Const VER_PLATFORM_WIN32_NT As Long = 2
Private Const HKEY_LOCAL_MACHINE As Long = &H80000002

Private Const ERROR_MORE_DATA = 234
Private Const ERROR_SUCCESS As Long = 0
Private Const KEY_QUERY_VALUE As Long = &H1
Private Const KEY_ENUMERATE_SUB_KEYS As Long = &H8
Private Const KEY_NOTIFY As Long = &H10
Private Const STANDARD_RIGHTS_READ As Long = &H20000
Private Const SYNCHRONIZE As Long = &H100000

KEY_QUERY_VALUE Or _
