Automatic shutdown
Advantech-DLoG DLT-V83 Series Manual V1.50 Page 91 of 122
Device shut down
If the operating system is shut down, all applications will be notified via the Windows message
“WM_QUERYENDSESSION” first.
Every application must then respond within the time set in the registry. If there is no response
within the preset time, the application will be hard-terminated.
It may not be possible to close an application automatically if it has unsaved data. Example: For
example, the WORDPAD.EXE program (included in Windows) cannot be closed automatically if
there are unsaved changes. In such a situation, WORDPAD.EXE will acknowledge the
“WM_QUERYENDSESSION” Windows message by prompting the user to choose whether to
save or not.
All applications that can be terminated without user confirmation using the keyboard shortcut
<ALT> + <F4> will normally also respond correctly to the “WM_QUERYENDSESSION” message
and therefore do not need to be hard-terminated.
To ensure that important data is saved correctly, the application must respond appropriately to
“WM_QUERYENDSESSION”, i.e. the backup data must be saved without user confirmation and
within the preset time.
