show Help file from Toolbar and Menu. [Resolved]

I have added a HelpProvider to my form.
when I press F1, the Help file pops out.

If I want to show the Help file by clicking the Help -> Menu or by clicking the Help icon in the Toolbar, how can I do this?

please guide, thank you.

perhaps my question is not clear enough. let me explain my problem again.

i add a menu to my form.
i also add a HelpProvider to associate the help file with my project.

how can i make this:
when i press at the menu item named Help, it should show the help file (.chm)

Code:

---

Private Sub mnuHelpHelp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuHelpHelp.Click

---

or when i press at one of the toolbar icon, it should show the help file (.chm)
:)

Code:

---

Private Sub ToolBar_ButtonClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs) Handles ToolBar.ButtonClick

---

what should i add in the code? i have no idea.

please guide me. THank you
