Code I use.... but not written by me:

Option Explicit
Option Private Module

Const HH_DISPLAY_TOPIC = &H0
Const HH_SET_WIN_TYPE = &H4
Const HH_GET_WIN_TYPE = &H5
Const HH_GET_WIN_HANDLE = &H6
Const HH_DISPLAY_TEXT_POPUP = &HE ' Display string resource ID or
' text in a pop-up window.
Const HH_HELP_CONTEXT = &HF ' Display mapped numeric value in
' dwData.
Const HH_TP_HELP_CONTEXTMENU = &H10 ' Text pop-up help, similar to
' WinHelp's HELP_CONTEXTMENU.
Const HH_TP_HELP_WM_HELP = &H11 ' text pop-up help, similar to
' WinHelp's HELP_WM_HELP.

Declare Function HtmlHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" _
(ByVal hwndCaller As Long, ByVal pszFile As String, _
ByVal uCommand As Long, ByVal dwData As Long) As Long


' HTML Help file launched in response to a button click:
Private Sub ViewHelpFile()

' hWnd is a Long defined elsewhere to be the window handle
' that will be the parent to the help window.

Dim hwndHelp As Long
Dim hWnd As Long

' The return value is the window handle of the created help window.
hwndHelp = HtmlHelp(hWnd, "myfile.chm", HH_DISPLAY_TOPIC, 0)

End Sub


' ' A specific topic identified by the variable ContextID is launched
' ' in response to this button click:
Private Sub HH_HELP_Click()
Dim hwndHelp As Long
'The return value is the window handle of the created help window.
hwndHelp = HtmlHelp(hWnd, "myfile.chm", HH_HELP_CONTEXT, ContextID)
End Sub
