The most dull question ever, you may think. But I do have problems with it.
How do you detect when your program unloads?
In my case it is closed using Taskmanager, the other ways work fine with Form_Unload. The form is not visible

The Form_Unload event isn't fired , and when I'm subclassing my form I only get one event, And that one is in the beginning.
I believe I'm doing something wrong with the Subclassing, here's my code:

Private Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hWnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long Private Const GWL_WNDPROC = (-4) Dim m_Hwnd As Long Dim PrevProc As Long Public Sub Hook(ByVal hWnd As Long)    If m_Hwnd <> 0 Then Unhook    m_Hwnd = hWnd    PrevProc = SetWindowLong(m_Hwnd, GWL_WNDPROC, AddressOf WindowProc) End Sub Public Sub Unhook()    SetWindowLong m_Hwnd, GWL_WNDPROC, PrevProc    m_Hwnd = 0 End Sub Private Function WindowProc(ByVal hWnd As Long, ByVal uMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long    Open "tmp.txt" For Append As #1       Print #1, uMsg    Close #1    WindowProc = CallWindowProc(PrevProc, hWnd, uMsg, wParam, lParam) End Function

Hi again :-)

Use the QueryUnload event in your form

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer) End Sub

and the unload mode has the following constants

[Pasted below from help]
The unloadmode argument returns the following values:

Constant Value Description
vbFormControlMenu 0 The user chose the Close command from the Control menu on the form.
vbFormCode 1 The Unload statement is invoked from code.
vbAppWindows 2 The current Microsoft Windows operating environment session is ending.
vbAppTaskManager 3 The Microsoft Windows Task Manager is closing the application.
vbFormMDIForm 4 An MDI child form is closing because the MDI form is closing.
vbFormOwner 5 A form is closing because its owner is closing.

Like I said in the first post, the Unload and QueryUnload events don't fire
(This occurs when you close it with the Taskmanager under (I believe) proccesses, when you have App.TaskVisible=false)

Got any other Ideas?

If you actually "terminate the process" then I don't think you will be notified in-program (the purpose for the most part is to kill a non-responsive program, in a worst-case-senario).

If you really want to know if that happens... I think you'd have to have 2 programs running, both monitoring if the other's closed, and if so do whatever's needed (like a virus does).
