I want to delay Windows shutdown in order to perform
some ops. I found the following code written in C, which
can easily be rewritten in Delphi :
DmcWndProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam )
{
switch (uMsg)
{
...
case WM_QUERYENDSESSION:
{
PostMessage(hWnd, UM_STARTBACKUP, 0, lParam);
return FALSE;
}
case UM_STARTBACKUP:
{
DmcBackupFiles();
ExitWindowsEx(lParam == ENDSESSION_LOGOFF? EWX_LOGOFF: EWX_SHUTDOWN, 0);
return TRUE;
}
...
}
}
But I don't know how to handle a reboot. In MSDN, they say
that lParam just tells if it's a logoff or a shutdown/reboot
with no way to differentiate the operation.
Is there a hidden way to perform what I want to do or it's
Windows which is *BAD* designed ?...
TIA
Jans
