bascially我的标题解释了我的问题。我使用的是OL2010,希望能够对整个电子邮件(不仅是“屏幕”)进行截图。Outlook:如何在不滚动的情况下制作整个电子邮件正文的屏幕截图
可以这样做吗?也许用VBA或外部程序?
谢谢! Mike

有一个similar question关于如何使用C#实现这个。请注意0,它解释了为什么有些情况下根本不可能。
有关如何截取屏幕截图的一些VB示例代码,请参阅Microsoft的this article。这里是最相关的部分:

嗨特雷布,感谢的人。编辑:哇这实际上似乎很好。我会尝试的! – Mike 2012-02-24 11:48:35
您是否知道我是否可以找出“未滚动区域”(实际下方)是否被渲染?或者你知道这是否也适用于OL? – Mike 2012-02-24 12:16:39
对不起,我没有办法找到编程,它取决于应用程序如何处理窗口的绘图。至于展望,我认为你将不得不尝试以找出... – Treb 2012-02-24 12:26:22
