in short:

i want to intercept suspend/standby messages on my laptop, but my program doesn't receives all relevant messages.

我想在我的筆記本電腦上截取掛起/備用信息，但是我的程序沒有收到所有相關的信息。

background:

there's a bug in ms-excel on windows xp/2k, which prevents system suspend if a file is opened on a network/usb drive.

windows xp/2k上的ms-excel有一個錯誤，如果在網絡/usb驅動器上打開文件，它可以防止系統掛起。

i'm trying to work-around it programmatically (my toolbox include python, vb6, or command line tools).

我正在嘗試以編程的方式工作(我的工具箱包括python、vb6或命令行工具)。

i know nothing about windows instrumentation :-)

我對windows設備一無所知:-)

i have a sysinternals utility that suspends the system anyhow. i want to hook it to the close-lid event!

我有一個sysinternals工具，不管怎么說，它掛起了系統。我想把它和這個封閉的活動聯系起來!

in long:

The notebook lid close (fujitsu u810) initiate the standby procedure [how?]

筆記本蓋關閉(富士通u810)啟動待機程序[如何?]

The system then send everybody WM_POWERBROADCAST: PBT_APMQUERYSUSPEND (i can trace them using SPYXX.EXE)

然后系統發送每個人WM_POWERBROADCAST: PBT_APMQUERYSUSPEND(我可以使用SPYXX.EXE跟蹤它們)

Every program answers "True", until excel answers "false", and the whole process stops.

每個程序都回答“True”，直到excel回答“false”，整個過程停止。

My questions:

1) my python program doesn't catch neither pbm_apmquerysuspend, nor PBT_APMQUERYSTANDBYFAILED, nor PBT_APMQUERYSUSPENDFAILED: ` ...

1)我的python程序既沒有捕獲pbm_apmquerysuspend，也沒有捕獲PBT_APMQUERYSTANDBYFAILED，也沒有捕獲PBT_APMQUERYSUSPENDFAILED: '…

query = "SELECT * FROM Win32_PowerManagementEvent"

power_watcher = wmi.ExecNotificationQuery ( query )

power_event = power_watcher.NextEvent ()

` it receives only PBT_APMSUSPEND, if standby finally occurs.

如果最終發生待機，它只接收PBT_APMSUSPEND。

Why not - and how do i intercept it?

為什么不呢?我怎么攔截它呢?

2) Is there another way to intercept the standby process?

2)是否有其他方法來攔截備用進程?

in a prefect world, i would set the lid-close event to run a command i choose. in a perfect world, lid-closure is a documented event.

在一個完美的世界里，我會設置關閉事件來運行我選擇的命令。在一個完美的世界里，閉蓋是一個有記錄的事件。

thank you all :-)

謝謝:-)

I've found an ugly workaround: I wrote an AutoIt script which detects the Excel's error MessageBox, closes it, and runs a sysinternals' utility which forces the computer to standby.

我發現了一個糟糕的解決方案:我編寫了一個AutoIt腳本，它可以檢測Excel的error MessageBox，關閉它，並運行sysinternals的實用程序，該實用程序強制計算機進行備份。

Opt("WinWaitDelay",400)

; -- exact text match, to save LOTS of cup cycles!

Opt("WinTitleMatchMode",3)

Opt("WinDetectHiddenText",1)

Opt("MouseCoordMode",0)

; Opt("WinSearchChildren",1)

dim $title = "Microsoft Excel"

dim $text = "Windows cannot go on standby because Microsoft Office documents or application components are being accessed from the network. You must close the open documents or exit the applications before you can put the computer on standby."

While True

; wait for excel's error msg

WinWait($title, $text)

Run("psshutdown.exe -c -d -accepteula -m mooshmoosh -t 5")

; the annoying msgbox doesn't close without the 'sleep'

Sleep(1000)

; close the annoying modal msgbox!

WinClose($title)

;1 minute delay, save cpu (?)

Sleep(1*60*1000)

WEnd

(this is an optimized version - the first trials were CPU intensive).

now it sits in the system-tray and just works.

(這是一個優化版本——最初的測試是CPU密集型的)。現在它位於系統托盤中，只是工作而已。

the lost messages question is still open. though i realized it has nothing to do with python in the first place.

丟失消息的問題仍然存在。雖然我首先意識到它與python無關。
