Add a Hyperlink to a SmartArt Node

阅读更多关于 Add a Hyperlink to a SmartArt Node

问题 In the Excel (also PowerPoint and Word) user interface it's possible to assign a hyperlink to a SmartArt node, or text in a node: Recording these steps in a macro yields an empty procedure. Trying to use logic with the object model yields no useful result (see code below). I tried the following three approaches: A SmartArtNode has a Shapes property and one can extract a Shape object... But the type belongs to the Office object model ( Office.Shape ) and cannot be coerced (that I can find) to

Yesterday I was trying to batch convert a group of PPTs into PDFs for a friend, and I decided to have a look at PowerShell, since it's been sitting on my HD for a while. Here's the code I've come up with. $p = new-object -comobject powerpoint.application # I actually don't know why I have to set the window to visible, # but it doesn't work otherwise, anyway, it's not the real problem I have $p.visible = 1 $f = $p.presentations.open('\some\file.ppt') $f.ExportAsFixedFormat('\some\newfile.pdf', 2) 2 is for PDF Since the "brute force" method didn't work ("type mismatch") I tried to import the

PPT那些令人叹为观止的功能，你玩转了吗？

阅读更多关于 PPT那些令人叹为观止的功能，你玩转了吗？

对于资深的PPT发烧友涞说具有无可比拟的魔力，它又有哪些让你相见恨晚的知识呢？ PowerPoint 作为一款备受欢迎的办公软件，很多用户只是知道常见的一些基础功能，而更深层次的功能，估计大部分人都不知道。 1、咱们就从“开始”说起： 1.1 【替换字体】指一键将A字体替换为B字体。当我们做了一个PPT，里面正文用的是宋体，但做好之后，我们觉得，正文用微软雅黑更好一点，我们点击【替换字体】，即可一键替换文件中所有宋体，变成微软雅黑。试想，如果没有这个功能，你要白费多少力气才能全部替换？ 1.2 【自定义设置默认字体】指我们将输入的文字字体默认为其他字体，而不是系统默认的宋体。举个例子，当我做一个PPT时，我会挑选字体，比如某一个案子，我选择了标题使用华康丽金黑简体，正文使用黑体。但大家都知道，系统默认的字体是宋体，如果我想使用黑体，我有两个选择：一是去替换，这是事后干预。二是直接开始就把黑体设置为默认的正文字体，这是事前干预。 PPT中的设置默认文本框功能，就是这个作用： 1.3 【PPT图层】指PPT中单个页面中所有元素的层级关系。很多人只知道PS有图层，但很少有人知道 PPT 的图层吗？这个图层有什么作用呢？大家都知道，当某一页PPT元素过多时，我们编辑起来会很麻烦，知道了图层的概念，我们就可以分层编辑，暂时不需要编辑的层可以选择隐藏。点击【选择】

问题 So I've got this macro that basically scans each slide in PowerPoint and sets the specified language. Works great. Howerver, it skips containers that aren't text boxes. I'd like it to apply the language on tables, smartart, charts etc. Basically anything that may contain text. Is this even possible? This is the current code: Public Sub changeLanguage() On Error Resume Next 'lang = "English" lang = "Norwegian" 'Determine language selected If lang = "English" Then lang = msoLanguageIDEnglishUK
