下列对象允许您在 Visual Studio 菜单和工具栏上创建、处理和操作命令。
| 对象名 | 说明 | 
|---|---|
| 对通过使用 AddNamedCommand2 方法添加到集成开发环境 (IDE) 的命令,提供确定此命令的状态或执行此命令的方法。 | |
| 表示 IDE 中的所有命令。 | |
| 表示 IDE 中的命令。 | |
| 为外接程序提供命令事件。 | |
| 为单击命令栏上的控件时所进行的操作提供一个 Click 事件。 | 
| .gif) 说明: | 
|---|
| 如果您的命令不再显示在相应的命令栏上,或者添加一个新命令或修改现有命令,或者希望重新创建命令,请关闭 Visual Studio 的所有实例并双击包含外接程序源代码的文件夹中名为 ReCreateCommands.reg 的文件。 | 
使用这些对象,可以:
- 添加或移除 Visual Studio IDE 中的命令栏(AddCommandBar 和 RemoveCommandBar 方法)。 
- 将新命名的命令添加到工具栏或菜单(AddNamedCommand2 方法)中。 
- 获取命令的状态(CommandInfo 和 QueryStatus 方法)。 .gif) 说明: 说明:- 无法为 CommandBar 控件连接 CommandBarEvents 事件,该控件为通过 AddNamedCommand2 添加的新命令而创建。 
| .gif) 说明: | 
|---|
| 显示的对话框和菜单命令可能会与“帮助”中的描述不同,具体取决于您现用的设置或版本。这些过程是使用“常规开发设置”开发的。若要更改设置,请在“工具”菜单上选择“导入和导出设置”。有关更多信息,请参见 Visual Studio 设置。 | 
示例
下面的示例使用:
- Command 对象。 
- AddNamedCommand 方法。 
- AddControl 方法。 
- IDTCommandTarget 接口。 
此过程演示如何将外接程序以命令的形式显示在 Visual Studio 中的“工具”菜单上。将代码的第一部分添加到您创建的外接程序的 OnConnection 方法中。在 Exec 和 QueryStatus 方法中,请确保 If cmdName = "MyAddin1.Connect.MyAddin1" Then 这一行代码反映您的外接程序的名称。
