Don't add a Help file in your project settings ...
Add this snippet to your MenuHelpIndex_Click

    cdlMain.HelpFile = App.Path & "\plt.hlp"
    cdlMain.HelpCommand = cdlHelpContents

(cdlMain = common dialog)

This will launch your help file

What do you mean with HTML Help ??

plt.hlp should be the name of your help file of course

Add the name of your .chm file in project settings.

Add the following declaration:

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

Private Sub mnuOnlinehelp_Click()
     Dim HelpFile As String, rc As Long

     Const HH_DISPLAY_TOPIC = &H0

        HelpFile = App.HelpFile
        rc = HTMLHelp(frmMainForm.hWnd, HelpFile, HH_DISPLAY_TOPIC, 0)
     End Sub
