HOW TO:新增和處理命令

更新:2007 年 11 月

下列物件允許您建立、處理及操作 Visual Studio 各功能表和工具列上的命令。

物件名稱

說明

IDTCommandTarget

使用 AddNamedCommand2 方法來提供方法,以決定加入至整合式開發環境 (IDE) 之命令的狀態或執行該命令。

Commands2

表示 IDE 中的所有命令。

Command

表示 IDE 中的某項命令。

CommandEvents

提供增益集 (Add-In) 的命令事件。

CommandBarEvents

提供按一下命令列上的控制項時的 Click 事件。

注意事項:

如果您的命令不再出現在適當的命令列上,或如果您加入新命令或修改現有的命令,或者想要重新建立命令,請關閉 Visual Studio 的所有執行個體,並在包含增益集原始程式碼之資料夾中的 ReCreateCommands.reg 檔案上按兩下。

使用這些物件,您可以:

注意事項:

根據目前使用的設定與版本,您所看到的對話方塊與功能表命令可能會與 [說明] 中所描述的不同。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

範例

下列範例會使用:

程序會示範如何使增益集顯示為 Visual Studio 中 [工具] 功能表上的命令。將第一個程式碼區段加入至您所建立之增益集的 OnConnection 方法。在 ExecQueryStatus 方法中,請確定程式碼行 If cmdName = "MyAddin1.Connect.MyAddin1" Then 可反映您的增益集名稱。
