如何：维护 Outlook 会话之间自定义工具栏的位置信息

此示例演示一种保存和还原 Outlook 自定义工具栏位置的可能方式。 代码创建工具栏并在用户退出 Outlook 时在用户设置文件中保存其位置。 重新启动 Outlook 会重新创建工具栏并根据保存的设置来设置其位置。

**适用于：**本主题中的信息适用于 Outlook 2007 的应用程序级项目。有关更多信息，请参见按 Office 应用程序和项目类型提供的功能。

编译代码

此示例需要：

• 五个用户设置。 双击项目的**“属性”（在 C# 中）或“我的项目”**（在 Visual Basic 中）文件夹中的 Settings.settings 图标，并添加下列用户范围的属性：

  • CommandBarTop, type int, default value = 0

  • CommandBarLeft, type int, default value = 0

  • CommandBarVisible, type boolean, default value = true

  • CommandBarPosition, type int, default value = 4

  • CommandBarRowIndex, type int, default value = 1
