Hi,

How does one adhere in VB6 to Restart Manager messages. Here is some text
that Microsoft provides in the WinQual tests for Win7. Would that be the
Form_QueryUnload? If so, am I to just return False there or what is
Microsoft expecting?

Thanks,

Sarah

Some applications as part of their first launch display EULAs or auto update
prompts, registration forms, etc. If your application performs in this way,
it could be falsely reported as non-compliant with the restart requirement.

If any of the above files are reported for this reason, you should restart
testing from a clean state (clean OS). This time around, before running the
/postinstall phase, execute any run-once functionality in the application
PRIOR to running the /postinstall phase of the toolkit.

IMPACT IF NOT FIXED: By failing to shutdown gracefully, customers could lose
data when the OS finally forces a shutdown. It also slows the
shutdown/reboot process, impacting performance perceptions.

HOW TO FIX: In a critical shutdown, applications that return FALSE to
WM_QUERYENDSESSION will be sent WM_ENDSESSION and closed, while those that
time out in response to WM_QUERYENDSESSION, will be terminated. By following
these guidelines, you can ensure that your application will handle critical
shutdowns gracefully:

WM_QUERYENDSESSION with LPARAM = ENDSESSION_CLOSEAPP(0x1): GUI 19
applications must respond (TRUE) immediately in preparation for a restart

WM_ENDSESSION with LPARAM = ENDSESSION_CLOSEAPP(0x1): Applications must
return a 0 value within 30 seconds and shut down. At a minimum, applications
should prepare by saving any user data and state information that is needed
after a restart

Console applications that receive CTRL_C_EVENT notification should shut down
immediately. Drivers must not veto a system shutdown event

More information and guidance on requesting and responding to system
shutdowns and the RestartManager is available HERE

Yes.

Normally you prompt and save in queryunload, cancelling if the user
requests it, and then shutdown in the unload.
If the user cancels, and it's an important shutdown, it will be terminated.

Do you know about the possible values of the "cancel"
parameter in QueryUnload?

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

# 4 and 5 might need a little extra attention,
making sure that you don't put porgram-closing
code in sub-windows. But in general it goes
something like this:

If cancel = 0 then
' ask about saving open files before closing and provide a cancel
option.
Else
' quit. Either the system or your own code is telling you to close.
End If

Woops. Thanks.
