BHO 是 Internet Explorer Web 瀏覽器的一種附加元件或擴充功能。它是一個動態連結程式庫 (DLL),透過提供附加功能或服務來擴充 Internet Explorer 的功能。

BHO 如何運作?

當您開啟 Internet Explorer 時,瀏覽器會載入所有已安裝的瀏覽器說明程式物件。這些 BHO 可以掛鉤各種事件並與瀏覽器的文檔物件模型 (DOM) 交互,以修改或增強網頁行為、提供額外的工具列按鈕、阻止彈出視窗、管理下載或執行其他任務。

如何使用 BHO 的範例是什麼?

假設您安裝了 BHO,可以增強您的 Web 瀏覽體驗。當您造訪網頁時,BHO 可能會偵測某些關鍵字並顯示相關資訊或提供對相關資源的快速存取。例如,如果您造訪技術新聞網站,BHO 可以突出顯示技術術語並提供相關文章或產品頁面的連結。

BHO是如何安裝的?

BHO 通常透過安裝程式或透過手動向作業系統註冊 BHO 的動態連結庫 (DLL) 檔案來安裝。安裝後,BHO 可用於 Internet Explorer,並在瀏覽器啟動時自動載入。

我可以刪除或停用 BHO 嗎?

是的,您可以刪除或停用 BHO。在 Internet Explorer 中,您可以透過瀏覽器的設定來管理 BHO。開啟「管理加載項」對話方塊並找到要刪除或停用的 BHO。從那裡,您可以選擇停用或刪除它。

BHO 是否有任何相關風險?

雖然 BHO 可以提供有用的功能,但也存在潛在的風險。一些設計不良或惡意的 BHO 可能會影響 Internet Explorer 的效能、導致崩潰,甚至引入安全漏洞。安裝 BHO 時務必謹慎,並確保它們來自可信來源。

BHO 可以追蹤我的瀏覽活動嗎?

是的,某些 BHO 可以追蹤您的瀏覽活動。他們可以監控您造訪的網站、您點擊的連結以及您在網頁表單中輸入的資訊。然而,信譽良好的 BHO 通常會遵守隱私權政策,不會濫用或分享您的個人資訊。

如何檢查 Internet Explorer 中安裝的 BHO?

若要檢查 Internet Explorer 中安裝的 BHO,請開啟瀏覽器並前往「管理加載項」設定。從那裡,選擇「工具列和擴充功能」類別,您將看到已安裝的 BHO 清單及其狀態(啟用/停用)。

我可以開發自己的 BHO 嗎?

是的,如果您有程式設計知識,您可以開發自己的 BHO。 BHO 通常使用 C++ 和組件物件模型 (COM) 等語言進行開發。 Microsoft 提供文件和資源來幫助開發人員開始 BHO 開發。

發展 BHO 需要哪些技能或程式設計知識?

開發 BHO 需要 C++ 程式設計知識並熟悉組件物件模型 (COM) 技術。了解超文本標記語言 (HTML)、JavaScript 和文件物件模型 (DOM) 操作等 Web 技術在建構 BHO 時也很有幫助。

BHO 可以與 Internet Explorer 以外的瀏覽器一起使用嗎?

不可以,BHO 特定於 Internet Explorer,與 Chrome 或 Firefox 等其他 Web 瀏覽器不相容。其他瀏覽器有自己的擴充框架和應用程式介面 (API),開發人員可以使用它們來擴展其功能。

BHO 可以在行動裝置或平板電腦上使用嗎?

BHO 特定於桌上型系統上的 Internet Explorer Web 瀏覽器,不適用於行動裝置或平板電腦。行動瀏覽器都有自己的擴充框架,例如Chrome for Android的WebView或Firefox for Android的Web Extensions,都提供了類似的功能。

BHO 會影響 Internet Explorer 的效能嗎?

是的,設計不當或資源密集的 BHO 可能會影響 Internet Explorer 的效能。消耗過多記憶體、大量使用中央處理單元 (CPU) 或引入相容性問題的 BHO 可能會導致瀏覽器速度變慢、凍結或崩潰。請務必注意您安裝的 BHO 及其對效能的影響。

BHO 會幹擾我電腦上的其他軟體嗎?

在某些情況下,BHO 可能會與電腦上的其他軟體發生衝突。例如,如果 BHO 掛接到系統級進程或修改某些瀏覽器設置,則可能會幹擾其他軟體的功能。使用來自可信任來源的 BHO 並監控其行為以最大程度地減少衝突至關重要。

BHO 是否可以用於惡意目的?

是的,不幸的是,一些 BHO 可能被用於惡意目的。惡意軟體作者可能會建立 BHO 來收集敏感資訊、注入不需要的廣告或將 Web 流量重新導向到惡意網站。安裝 BHO 時務必謹慎,並確保它們來自信譽良好的來源。

BHO 可以用來阻止廣告或彈出視窗嗎?

是的,一些 BHO 旨在阻止廣告或彈出視窗。他們可以分析網頁內容並封鎖某些元素的顯示,例如橫幅廣告或侵入性彈出視窗。這些 BHO 可以提供更精簡、更簡潔的瀏覽體驗。

BHO 可以用來管理下載或增強檔案處理嗎?

當然,BHO 可以提供下載管理功能或增強 Internet Explorer 中的檔案處理。它們可以攔截下載請求,提供下載進度指示器,對下載的檔案進行分類,或與外部下載管理器整合以增強瀏覽器的內建功能。

BHO 可以用於網站測試或自動化目的嗎?

是的,BHO 可用於網站測試或自動化。透過與瀏覽器的文件物件模型 (DOM) 交互,BHO 可以模擬使用者操作、從網頁中提取資訊或產生自動化測試。他們可以協助完成網頁抓取、資料擷取或自動表單填寫等任務。

BHO 是否與最新版本的 Internet Explorer 相容?

BHO 主要是為舊版的 Internet Explorer 設計的。隨著向現代 Web 標準的轉變和新瀏覽器的引入,對 BHO 的相關性和支持已經減弱。最新版本的 Internet Explorer 可能對 BHO 使用有限製或限制,較新的瀏覽器提供替代擴充框架。

BHO 能否用於增強 Internet Explorer 中的安全功能?

是的,BHO 可以增強 Internet Explorer 中的安全功能。它們可以提供即時保護,防止網路釣魚嘗試、惡意下載或不安全的網站。 BHO 可以利用已知威脅的資料庫或採用啟發式方法來偵測和阻止可疑活動,從而提高瀏覽器的安全性。

BHO 可以用來監控和過濾網路流量嗎?

是的,BHO 可以透過攔截和分析 Internet Explorer 發出的網路請求來監控和過濾 Internet 流量。他們可以阻止對特定網站或內容類別的訪問,實施內容過濾策略,或透過代理伺服器重定向流量以進行額外的監視和控制。

BHO 可以用來擷取 Web 表單上的使用者輸入嗎?

是的,BHO 可以擷取 Web 表單上的使用者輸入。透過連接到文件物件模型 (DOM),BHO 可以攔截按鍵、滑鼠點擊和表單提交。他們可以收集用戶輸入的資料、提供自動填充建議或實現自訂驗證邏輯。

BHO 可以與其他瀏覽器擴充功能互動嗎?

BHO 特定於 Internet Explorer,不具備與為其他瀏覽器開發的擴充功能的直接互動功能。但是,某些 BHO 可能會與其他系統級軟體或瀏覽器插件集成,以增強功能或實現互通性。
