show/hide systray clock

What API calls can be used to show/hide the systray
clock if it is not showing as if you right click on the
taskbar, click Properties, and uncheck Show Clock?

This code does not work:

Code:

---

lHwnd = FindWindowEx(0, 0, "Shell_TrayWnd", vbNullString)
lHwnd = FindWindowEx(lHwnd, 0, "TrayNotifyWnd", vbNullString)
lHwnd = FindWindowEx(lHwnd, 0, "TrayClockWClass", vbNullString)
Call ShowWindow(lHwnd, 5)

Try this:

Code:

---

Private Declare Function FindWindowEx _
Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As _
Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, _
ByVal lpsz2 As String) As Long

Private Declare Function ShowWindow Lib "user32" _
(ByVal hwnd As Long, ByVal nCmdShow As Long) As _
Long


Dim shelltraywnd As Long, traynotifywnd As Long, trayclockwclass As Long

Private Sub Form_Load()
    shelltraywnd = FindWindowEx(0, 0, "shell_traywnd", _
    vbNullString)
    traynotifywnd = FindWindowEx(shelltraywnd, _
    0&, "traynotifywnd", vbNullString)
    trayclockwclass = FindWindowEx(traynotifywnd, _
    0&, "trayclockwclass", vbNullString)
    ShowWindow trayclockwclass, 5
End Sub
