使用Open XML SDK合并powerpoint幻灯片后，无法编辑表格或图表数据 [英] Can't edit the table or chart data after merging the powerpoint slides using Open XML SDK

问题描述

我使用Open XML SDK将多个powerpoint文档合并为一个。我们在这些powerpoint文档上有一些可以编辑的表格和图表。

我使用了文章中描述的合并powerpoint文档的类似过程。

http://openxmldeveloper.org/blog/b/openxmldeveloper/ archive / 2011/01/28 / 110420.aspx

但是一旦合并这些，我就无法编辑表/图表数据并显示错误

"无法找到服务器应用程序，源文件或项目，或者返回了一个未知错误。您可能需要重新安装服务器应用程序"

我在某些地方读过，如果文档是压缩的，则可能会发生这种情况格式。我不确定如何在open xml中对其进行编辑。

感谢您的帮助。

以下是示例代码

 

  PresentationDocument myMonthlyDeck = null;

   myMonthlyDeck = PresentationDocument.Open（" output.pptx"，true）;

   VAR inputFilePaths = Directory.GetFiles（QUOT; \\input"，" * PPTX"。）;

的foreach（字符串中inputFilePaths pptname）

                {

$


               ;        MergeSlides（pptname，myMonthlyDeck）;

      



                }

       static void MergeSlides（string sourcePresentation，PresentationDocument myDestDoc）

        {

            int id = 0;



            {

                PresentationPart destPresPart = myDestDoc.PresentationPart;



             &NBSP ;  如果（destPresPart.Presentation.SlideIdList == NULL）

               &NBSP ;    destPresPart.Presentation.SlideIdList =新SlideIdList（）;

感谢您对MSDN论坛发帖。

您在你的程序失去TableStylePart / ChartPart。

我希望它可以帮到你。

祝你有个美好的一天，

Hi,

I used Open XML SDK to merge multiple powerpoint documents into one.We have some of the tables and charts on these power point documents which can be editable.

I used similar process which is described in the articleto merge powerpoint documents.

http://openxmldeveloper.org/blog/b/openxmldeveloper/archive/2011/01/28/110420.aspx

But once these are merged, I can't edit the tables / charts data and displays the error

"The server application, source file, or item can’t be found, or returned an unknown error. You may need to reinstall the server application"

I read in some places that it may happen if the document is in compressed format. I am not sure how to make it editable in open xml.

I appreciate your help.

Here is the sample code

 

  PresentationDocument myMonthlyDeck = null;
   myMonthlyDeck = PresentationDocument.Open("output.pptx", true);

   var inputFilePaths = Directory.GetFiles("\\input","*.pptx");

foreach (string pptname in inputFilePaths)
                {


                     MergeSlides(pptname, myMonthlyDeck);
      

                }

       static void MergeSlides(string sourcePresentation, PresentationDocument myDestDoc)
        {
            int id = 0;

            {
                PresentationPart destPresPart = myDestDoc.PresentationPart;

                 if (destPresPart.Presentation.SlideIdList == null)
                    destPresPart.Presentation.SlideIdList = new SlideIdList();

                PresentationDocument mySourceDeck = PresentationDocument.Open(sourcePresentation, false);
                // using ()
                {
                    PresentationPart sourcePresPart = mySourceDeck.PresentationPart;

                    // Get unique ids for the slide master and slide lists for use later.
                    uniqueId = GetMaxSlideMasterId(destPresPart.Presentation.SlideMasterIdList);
                    uint maxSlideId = GetMaxSlideId(destPresPart.Presentation.SlideIdList);

                    // Copy each slide in the source presentation in order to the destination presentation.
                    foreach (SlideId slideId in sourcePresPart.Presentation.SlideIdList)
                    {
                        SlidePart sp;
                        SlidePart destSp;
                        SlideMasterPart destMasterPart;
                        string relId;
                        SlideMasterId newSlideMasterId;
                        SlideId newSlideId;

                        // Create a unique relationship id.
                        id++;
                        sp = (SlidePart)sourcePresPart.GetPartById(slideId.RelationshipId);
                        string filename = Path.GetFileName(sourcePresentation).Replace(" ", "c");
                        relId = "c" + filename.Trim() + id;

                        // Add the slide part to the destination presentation.
                        destSp = destPresPart.AddPart<SlidePart>(sp, relId);

                        // The master part was added. Make sure the relationship is in place.
                        destMasterPart = destSp.SlideLayoutPart.SlideMasterPart;
                        destPresPart.AddPart(destMasterPart);

                        // Add slide master to slide master list.
                        uniqueId++;
                        newSlideMasterId = new SlideMasterId();
                        newSlideMasterId.RelationshipId = destPresPart.GetIdOfPart(destMasterPart);
                        newSlideMasterId.Id = uniqueId;

                        // Add slide to slide list.
                        maxSlideId++;
                        newSlideId = new SlideId();
                        newSlideId.RelationshipId = relId;
                        newSlideId.Id = maxSlideId;

                        destPresPart.Presentation.SlideMasterIdList.Append(newSlideMasterId);
                        destPresPart.Presentation.SlideIdList.Append(newSlideId);
                    }

                    // Make sure all slide ids are unique.
                    FixSlideLayoutIds(destPresPart);
                }

                // Save the changes to the destination deck.
                destPresPart.Presentation.Save();
                mySourceDeck.Close();
            }

        }

Hi VM7258,

Thanks for posting in the MSDN Forum.

You lost TableStylePart/ChartPart in your program.

I hope it can help you.

Have a good day,
