问题 I currently have a powerpoint with a chart that was generated through an excel. What I need to do is get the values of the chart (or the excel, doesn't matter) in order to do some animations. The problem is that I can't seem to get my code to work. If there is ANY easier way to do this I will be glad to hear it!

I have previously tried making All_Folder a function, and trying to return the value from the function, but that has gotten me nowhere. This is my code now: Public file_locations() As String Sub Some_Subroutine() Dim

问题 When I install my VSTO-based PowerPoint plugin, it always shows up in the 'disabled' section and everytime I open PowerPoint - I have to manually enable it. How do I programmatically change this behaviour such that plugin is always enabled by default. 回答1: When you set an Office (VSTO) addin to be enabled (in Office), it changes the registry key: HKLM\SOFTWARE\Microsoft\Office\PowerPoint\Addins\YourAssemblyName "LoadBehavior" The LoadBehavior value must be set to 3 to load (ie enabled) (2 is

问题 I have a Java program in which I want to copy PowerPoint slides from one presentation into another. I have looked into the "Slides" API in Apache POI, but can't find any reference to a capability like that there. Though the calling program will be Java, I'm open to the idea of the actual work being in another language. For example, I could run on Windows and call a COM component through JACOB or something. How can I best achieve this? Also for clarification, I need to support both PPT and

问题 I am trying to add a title to my slide . I was looking up the documentation here and it says, "Setting the slide title Almost all slide layouts have a title placeholder, which any slide based on the layout inherits when the layout is applied.
