Guys,

I have an application without user interface (kind of service).
To close it I am using task manager (not very nice solution). I want to add an icon to notification area with simple menu poping up with only "Exit" item. Is it possible to do without using form to app?
I know how to put icon, but menu?

Thanks,

Michael

The book Custom Controls Library includes a control that manipulates the system tray and another that animates a system tray icon. For more information go to www.vb-helper.com/ccl.htm.
Use a hidden form to display the icon and manage tray menus.

Set ShowInTaskBar = False so the form's icon doesn't appear in the task bar. Set Visible = False so the form doesn't apear. Give the form an appropriate icon.

When the program starts, it calls AddToTray to add itself to the system tray. It then calls SetTrayTip to give its system tray icon a tooltip.
 
 
 
Private Sub Form_Load()
    AddToTray Me, mnuTray

    SetTrayTip "VB Helper ""formless"" tray icon program"
End Sub
 
 
 
Subroutine AddToTray gives the form a new WindowProc so it can look for tray events. It then uses the Shell_NotifyIcon API function to make the tray icon. Note that the data structure sets .hIcon = frm.Icon.Handle so the tray icon uses the form's icon.  
 
 
' Add the form's icon to the tray.
Public Sub AddToTray(frm As Form, mnu As Menu)
    ' ShowInTaskbar must be set to False at
    ' design time because it is read-only at
    ' run time.

    ' Save the form and menu for later use.
    Set TheForm = frm
    Set TheMenu = mnu
   
    ' Install the new WindowProc.
    OldWindowProc = SetWindowLong(frm.hwnd, _
        GWL_WNDPROC, AddressOf NewWindowProc)
   
    ' Install the form's icon in the tray.
    With TheData
        .uID = 0
        .hwnd = frm.hwnd
        .cbSize = Len(TheData)
        .hIcon = frm.Icon.Handle
        .uFlags = NIF_ICON
        .uCallbackMessage = TRAY_CALLBACK
        .uFlags = .uFlags Or NIF_MESSAGE
        .cbSize = Len(TheData)
    End With
    Shell_NotifyIcon NIM_ADD, TheData
End Sub
 
 
 
Subroutine SetTrayTip uses Shell_NotifyIcon to set the tray icon's tooltip.  
 
 
' Set a new tray tip.
Public Sub SetTrayTip(tip As String)
    With TheData
        .szTip = tip & vbNullChar
        .uFlags = NIF_TIP
    End With
    Shell_NotifyIcon NIM_MODIFY, TheData
End Sub
 
 
 
When the new WindowProc sees the WM_NCDESTROY message, it calls RemoveFromTray to remove the tray icon and restore the original WindowProc. If you do not remove the tray icon, it remains in the tray but doesn't work properly.
If the new WindowProc sees a TRAY_CALLBACK message, it checks the event in more detail. If the user right clicked the icon, the program displays a popup menu that contains Do Stuff and Close commands. Do Stuff displays a message box. Close unloads the program's form.
 
 
 
' The replacement window proc.
Public Function NewWindowProc(ByVal hwnd As Long, ByVal Msg _
    As Long, ByVal wParam As Long, ByVal lParam As Long) As _
    Long
Const WM_NCDESTROY = &H82

    ' If we're being destroyed, remove the tray icon
    ' and restore the original WindowProc.
    If Msg = WM_NCDESTROY Then
        RemoveFromTray
    ElseIf Msg = TRAY_CALLBACK Then
        ' The user clicked on the tray icon.
        ' Look for click events.
        If lParam = WM_RBUTTONUP Then
            ' On right click, show the menu.
            SetForegroundWindow TheForm.hwnd
            TheForm.PopupMenu TheMenu
            If Not (TheForm Is Nothing) Then
                PostMessage TheForm.hwnd, WM_NULL, ByVal _
                    0&, ByVal 0&
            End If
            Exit Function
        End If
    End If

    ' Send other messages to the original
    ' window proc.
    NewWindowProc = CallWindowProc( _
        OldWindowProc, hwnd, Msg, _
        wParam, lParam)
End function

As I understand there is no way to do this without form, right?

HIDDEN FORM IS A FORM AS WELL!
Application that use hidden form cannot be called "formless" application

Please forget about TrayIcon.

the question is: HOW TO CREATE PopUpMenu WITHOUT form (NO HIDDEN FORM, PLEASE)

You have to create the first item in design-time, but you can dynamically add items in runtime using a control array. You can hide the items you create in runtime using Hide method or setting the Visible property to False

basically you need a form sorry.
