我使用WMI監視進程創建事件使用WMI監視進程的創建活動
根據其他職位(How to detect win32 process creation/termination in c++)
我按照它來註冊我的回調函數,但它不工作。
什麼都沒有發生,當我運行這個程序,並打開IEXPLORE
請幫幫我,謝謝

建議 - 嘗試省略'AND TargetInstance.Name =「iexplore.exe''條款,以確保您的回調當任何*進程啓動時調用。如果有效,請嘗試排除其他過濾條件。 –
我曾嘗試過,但它不起作用 –
此MSDN文章看起來像幾乎完全一樣你想要做的(沒有進程名稱過濾器)。我會深入探討所有步驟,看看你是否能夠運行。另外,如果以管理員身份運行,我會對知道它是否以不同的方式工作感興趣。 [示例:通過WMI接收事件通知](https://msdn.microsoft.com/en-us/library/aa390425(v = vs.85).aspx) –
