HOW TO：回應 ClickOnce 發行事件

ClickOnce 可以讓您將 Windows 應用程式發行至 Web 伺服器或與簡易安裝共用的網路檔案。如需詳細資訊，請參閱 ClickOnce 安全性和部署。

Visual Studio 核心 Automation 模型 (包含在 EnvDTE80 中) 有一個名為 PublishEvents 的事件處理物件。您可以利用此物件偵測 ClickOnce 部署何時開始 (OnPublishBegin) 以及何時結束 (OnPublishDone)。您可以根據這些事件來執行動作。在下列程序中，會示範如何處理這些事件。

注意事項
根據您目前使用的設定或版本，您所看到的對話方塊與功能表指令可能會與 [說明] 中描述的不同。使用 [一般開發設定] 開發了這些程序。若要變更設定，請從 [工具] 功能表中選擇 [匯入和匯出設定]。如需詳細資訊，請參閱 Visual Studio 設定。

若要回應 ClickOnce 事件

1. 在新的或現有的增益集 (Add-In) 中，將下列程式碼加入至 Connect 類別。

2. 依照 HOW TO：使用增益集管理員來控制增益集中所描述的方式，建置 (Build) 並啟動增益集。

3. 依照 ClickOnce 安全性和部署中所描述的方式，開始 ClickOnce 部署作業。

   當部署開始和結束時，您都會看見一個訊息方塊。
