Private Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean
Dim t As NOTIFYICONDATA

Private Sub Form_Load()
quit = 0
t.cbSize = Len(t)
t.hWnd = Picture1(0).hWnd
t.uId = 1&
t.uFlags = NIF_ICON Or NIF_TIP Or NIF_MESSAGE
t.ucallbackMessage = WM_MOUSEMOVE
t.hIcon = Picture1(0).Picture
t.szTip = "Show MY Icons" & Chr$(0)
