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 |
|---|---|
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。 |
|
表示 IDE 中的所有命令。 |
|
表示 IDE 中的某項命令。 |
|
提供增益集 (Add-In) 的命令事件。 |
|
提供按一下命令列上的控制項時的 Click 事件。 |
.gif "注意事項") 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：
加入或移除在 Visual Studio IDE 中的命令列 (AddCommandBar 和 RemoveCommandBar 方法)。
在工具列或功能表上加入新的具名命令 (AddNamedCommand2 方法)。
取得命令的狀態 (CommandInfo 和 QueryStatus 方法)。
注意事項：對於使用 AddNamedCommand2 加入的新命令所建立的 CommandBar 控制項，您不能為它連接 CommandBarEvents 事件。
| 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：
Command 物件。
AddNamedCommand 方法。
AddControl 方法。
IDTCommandTarget 介面。
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 Exec 和 QueryStatus 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。
