例外狀況

InvalidOperationException

目前情境下不支援系統事件通知。 例如，伺服器程序可能不支援全域系統事件通知。

ExternalException

嘗試建立系統事件視窗執行緒的嘗試未能成功。

備註

此事件結束了WM_COMPACTING訊息。 當系統偵測到在 30 到 60 秒間內，超過 12.5% 的系統時間被用於壓縮記憶體時，此訊息會發送給所有頂層視窗。 這表示系統記憶體不足。

Note

此事件僅在訊息泵運行時觸發。 在 Windows 服務中，除非使用隱藏表單或訊息泵已被手動啟動，否則此事件不會被觸發。 若想了解如何在 Windows 服務中使用隱藏表單來處理系統事件，請參見 該類別。SystemEvents

注意事項

由於這是靜態事件，應用程式被丟棄時必須分離事件處理器，否則會導致記憶體洩漏。

給呼叫者的注意事項

此訊息僅為相容 16 位元 Windows 應用程式而提供。
