Is there a "Reset Slide" method for presentations in OpenXML SDK 2.5?

Hello, 

I am relatively new to C# and OpenXML.  I'm trying to use OpenXML to fix a very specific issue I'm having.  I have thousands of PowerPoint slides that are generated by Nintex DrawLoop pulling content and data from Salesforce.  Once Nintex generates the slides, they must be manually opened and the "Reset Slide" option on the context menu must be executed to apply the formatting of the Master Slide/Layout.  I have been unable to find a way to automate this step through VBA or Interopt.  I'm hoping I can accomplish this through OpenXML but so far my searching has not turned anything up.

Finding a way to automate this one manual step would be a huge help to me.  The menu option can be found when you right click a slide in the slide selector.  The menu option can also be found on the ribbon under Home|Slides|Reset

Thanks for your help.

My requirement is to export huge records with rows equal to 5 lakhs. I was using OpenXml approach like this :

            using (var workbook = SpreadsheetDocument.Create(destination, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
            {

                    if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)

                        colRow.AppendChild(cell);

        }

        

But now i have requirements in which data to be exported can be up to 10 lakh records with substantial number of columns. So i had to implement OpenXml Sax type approach as DOM approach is bit slow and memory consuming in case of large data.

I couldn't find any helpful link which shows me how to use that approach and convert data table/data set to excel. In most link they are using existing spreadsheet to create new excel. Can anyone provide changes to be made to above code to implement SAX approach or any link regarding the same.

Any help is deeply appreciated

Embedded Font not working in Powerpoint

Hi,

our web-app generates pptx files with the openxml-sdk and we use custom fonts (Roboto). The pptx files contains roboto as embedded font, textfields and metafiles(emf).

The textfields working well with the custom fonts, but the metafiles display text in arial. Only if i ungroup the metafile and convert into microsoft office drawing object the embedded font is used. The metafile is created on serverside with roboto font.

The question is: How can i ungroup the metafile before the file is saved and transmitted to the client? Or what can i do, that powerpoint uses the embedded font also for the includes metafile?

Thank you.

Hi, Everyone

I hope someone can help me I'm at my wits end!

Scenario:

Export large set of data from Datatable (i.e. List of clients with some related details) - the Datatable may be different on every export.  This may range from a couple of hundred to a couple of million rows of data.

I need to be able to create a new blank .xlsx file, export the details if the details span more than one sheet append extra sheets until the whole datatable is exported.

I cannot use the existing template approach with is used in 100% of example code in all SAX approaches with OpenXML and after days of trying I just cannot anymore!

Does anyone know of references that may guide me in the right direction here?

OpenXml SDK- How to uniquely identify a paragraph in a word document

I need to extract paragraphs based on some unique ids or something that can identify/differentiate each paragraph in a 50- 60 pages word document (using TX Text Editor to load it) . I will tag these unique IDs to a list box or some other list control and on-click of the list box item, go to that specific paragraph and highlight it. I thought w:paraID is unique but it is null and not for development purpose. There should be some custom hack where in i can add something.

Right now i convert the TxText Editor loaded content to docx -> wordprocessingML and trying to figure out how to extract certain paragraphs using some unique ids or style. The Content of the Paragraph will not be known, only some mapping between the listitem and Docx will be there to highlight the entire paragraph.

Programmatically update Word Link/Embedded Files Source Location

Hi I'm not sure if I posted this in the right forum, so please feel free to point me in the right direction.
We are in the middle of migrating thousands of Word and Excel (Office 2010) files from Novel servers to Windows servers.

The issue we have is that the vast majority of this Word documents have link or embedded Excel files.
We need to update the source file location in the Word files and manually doing so is out of the question, this will be an impossible task.

I have search and found .NET code that will modify the source location of link/embedded files in Word.

Is there a way to accomplish this automatically or with minimum manual intervention?
Is there any sample code that I can modify to accomplish this?
I'm using VS2012 and VB (I know this is not the best, I should use C#).
Any advice will be greatly appreciated
