WPF如何调用PPT的笔和橡皮工具？

Question

WPF如何调用PPT的笔和橡皮工具，我现在要操作PPT，比如我点击一个按钮，就点击ppt程序上【笔】这个选项，现在可以操作上一页、下一页功能。

Answer 1

Hi，

查看MSDN：Microsoft.Office.Interop.PowerPoint Namespace 之后，只发现 SlideShowView.PointerType Property 。

https://msdn.microsoft.com/en-us/library/microsoft.office.interop.powerpoint.slideshowview.pointertype(v=office.14).aspx

要将Pointer更改为笔或者橡皮，可以将PointerType属性设置为ppSlideShowPointerPen或者ppSlideShowPointerEraser。

Best Regards，

Bob

Answer 3

顺便问下，PPT可以承载到一个Panel容器了吗？

Answer 4

Hi,

你说的承载...是指嵌入PowerPoint程序到WPF程序,还是单独的显示PPT文档？

嵌入PowerPoint程序，你可以使用Win32 api SetParent().

显示PPT文档，你可以选择WebBrowser。

Answer 7

本地文档，我现在是C#操作PPT文档，可以承载到窗体里，但是不怎么承载到容器里。

 //嵌入窗体
             var fromVisual = (HwndSource)PresentationSource.FromVisual(this) as HwndSource;
             if (fromVisual == null)
             {
                 return;
             }
             var parentHwnd = fromVisual.Handle;
             SetParent(wn, parentHwnd);

Answer 8

Hi，

WPF中，所有元素和窗体共用一个句柄， 你不能获取Canvas的句柄。所以你不能SetParent 到Canvas上。

变通方案是Host Winform的控件，例如panel，然后在panel上承载。
