从ppt演示文稿中选择特定幻灯片并粘贴excel图表

select certain slide from ppt presentation and paste excel chart(从ppt演示文稿中选择特定幻灯片并粘贴excel图表)

问题描述

我使用以下代码打开工作表、复制一个图表、打开演示文稿并粘贴它。

它可以很好地处理一个图表和一张幻灯片，但是在XLSM中有8个图表，所以8张pptx格式的幻灯片，我不知道如何选择第二个图表并将其粘贴到演示文稿的第二张或第三张幻灯片中。

使用PowerPoint.Slide curSlide=pptApp.ActiveWindow.View.Slide；可选择当前幻灯片或幻灯片1。

推荐答案

使用此代码解决了问题：

p = pptApp.ActivePresentation; 
slides = p.Slides; 
slides[3].Select(); 
Ppt.Slide slide3 = pptApp.ActiveWindow.View.Slide;
