No need for API.

Private Sub Form_QueryUnload (Cancel As Integer, UnloadMode As Integer)
   If UnloadMode = 2 Then
       Msgbox "Windows is shutting down"
   End If
End Sub

hi

u can do this from sysinfo object

[chrisjk]

no no no, that code is placed in the unload event of a form. When Windows shutsdown, it attempts to close everything, including your forms. If you have that code, it will display the message box when you shutdown windows.

i tried to put the Form_queryunload code as suggested by mathew gates but it does not work....i donno why but the unloadmode never becomes 2???
please help with ode ...if possible!

You might not get the response in case of Forced Shutdown.

Please Suggest!

Subclass your main form and look for the WM_QUERYENDSESSION
message. This is what the systems sends while shutting down the system

Most of the time, I believe you will get the Msgbox, but even if OK is there, it will close the Msgbox automatically.
