Pop up menu from system tray

I need a code example to popup a menu from an Icon I set into the system tray.
when I try to pop up a menu using 3rd party tool as the Sheridan toolbar I get an error that the form is not visible.

Add an Invisible Picturebox to a Form, set the Form's ShowInTaskbar Property to False, add a Menu called mnuPopup with SubItems called, mnuShow and mnuExit..

Private Type NOTIFYICONDATA
        cbSize As Long
        hwnd As Long
        uID As Long
        uFlags As Long
        uCallbackMessage As Long
        hIcon As Long
        szTip As String * 64
End Type

Private Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

Private Const NIF_ICON = &H2
Private Const NIF_MESSAGE = &H1
Private Const NIF_TIP = &H4
Private Const NIM_ADD = &H0
Private Const NIM_DELETE = &H2
Private Const WM_MOUSEMOVE = &H200
Private Const WM_RBUTTONUP = &H205
Private Const WM_LBUTTONDBLCLK = &H203
Private Const WM_LBUTTONDOWN = &H201
Private Const WM_LBUTTONUP = &H202

Private tTrayIcon As NOTIFYICONDATA

Private Sub Form_Load()
    With tTrayIcon
        .hIcon = Icon
        .hwnd = Picture1.hwnd
        .szTip = Caption & Chr(0)
        .uCallbackMessage = WM_MOUSEMOVE
        .uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP
        .uID = 1
        .cbSize = Len(tTrayIcon)
    End With
    Shell_NotifyIcon NIM_ADD, tTrayIcon
End Sub

Private Sub Form_Resize()
    If WindowState = vbMinimized Then
        Hide
        WindowState = vbNormal
    End If
End Sub

Private Sub Form_Unload(Cancel As Integer)
    Shell_NotifyIcon NIM_DELETE, tTrayIcon
End Sub

Private Sub mnuExit_Click()
    Unload Me
End Sub

Private Sub mnuShow_Click()
    Show
End Sub

Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Select Case ScaleX(X, vbTwips, vbPixels)
    Case WM_LBUTTONDBLCLK
        'Double Click on SysTray Icon to Show Form
        Show
    Case WM_RBUTTONUP
        'Used for Displaying a Popup Menu
        Me.PopupMenu mnuPopup
    End Select
End Sub
