更新：2007 年 11 月
告知 ToolWindows 是否為可見的 (隱藏或顯示)。請使用這個物件的功能，並且參考 WindowVisibilityEventsClass，以取得此物件的說明文件。
命名空間： EnvDTE80
組件： EnvDTE80 (在 EnvDTE80.dll 中)

Public Interface WindowVisibilityEvents _
Implements _WindowVisibilityEvents, _dispWindowVisibilityEvents_Event
Dim instance As WindowVisibilityEvents

範例
這個範例中，會使用增益集來連接 WindowVisibilityEvents。以下列範例程式碼取代 Connect.vb 或 Connect.cs 檔案中的程式碼。在 Visual Studio IDE 中執行增益集，並開啟 [命令視窗] 以及關閉 [輸出視窗]，讓事件擷取方法運作。如需如何執行 Automation 範例的詳細資訊，請參閱 HOW TO：編譯和執行 Automation 物件模型程式碼範例。
