c# - 如何在 outlook 窗口中为收件箱中的邮件创建一个按钮(双击邮件)？

Question

我是程序员菜鸟，我必须创建 outlook 2007 加载项。我应该在功能区或任务栏上创建一个按钮，但在收件箱中的单个邮件的窗口上。您知道，当您双击收件箱中的邮件时，会出现新窗口。在那个窗口中，我需要一个按钮来打开一个带有一些 TreeView 的新表单。我的主要问题是如何创建该按钮。这对我来说是全新的，所以我将非常感谢您的帮助。

好吧，我已经做了一些研究，下面的这段代码有点管用 :) 但如果有经验的人能看到它并告诉我它是否可以以及我可以更改它的内容和方式，我将不胜感激。这只是更大项目的开始。
