How to convert a "dotx" into docx file with c# and open Xml that contains building block?

Dear all,

I have a big problem I generate docx from document template dotx that contains building block but I have no more the possibility to select my building block.

  here is my code

 MemoryStream documentStream;
                String templatePath = Path.Combine(Environment.CurrentDirectory, @"path of the dotx");
                using (Stream tplStream = File.OpenRead(templatePath))
                {

                    documentStream = new MemoryStream((int)tplStream.Length);
                    CopyStream(tplStream, documentStream);
                    documentStream.Position = 0L;
                }
                using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
                {

                    template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);

                    MainDocumentPart mainPart = template.MainDocumentPart;

                    mainPart.DocumentSettingsPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",

                       new Uri(templatePath, UriKind.Absolute));



                    mainPart.Document.Save();

                }



                string path = @"path of the new doc";

                File.WriteAllBytes(path, documentStream.ToArray());



                // Run Word to open the document:

                System.Diagnostics.Process.Start(path);

do you have any idea how I can mange with the building block

Hi,

   To convert from dotx to docx you can refer this post.

it's exactly what i do but I have building block and by this method I have no possibility to select it

when I compare by doing the operation manually I see that the folder glossary inside the word folder is missing

sorry I made a mistake the folder glossary is here , the linked with the template is made in the file app.xml from folder docProps and the path of the template is displayed in settings.xml.rels  of the fodler word\_rels

but the list of building block is not available

Hi,

  Can you please send any screen shots, dotx file & the code which you are trying?

Thanks for your help.

You can find in attachment a zip file with the template and the document produced.

If you look at the document produced you can see that it's no more possible to select a building block.

The template and the docuemnt generated are in the same folder.

Here is the code

  static void Main(string[] args)
        {

            try
            {              
                MemoryStream documentStream;
                String templatePath = Path.Combine(Environment.CurrentDirectory, @"path of the dotx");
                using (Stream tplStream = File.OpenRead(templatePath))
                {
                    documentStream = new MemoryStream((int)tplStream.Length);
                    CopyStream(tplStream, documentStream);
                    documentStream.Position = 0L;
                }
                using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
                {

                    template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
                    MainDocumentPart mainPart = template.MainDocumentPart;
                    mainPart.DocumentSettingsPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",new Uri(templatePath, UriKind.Absolute));
                    mainPart.Document.Save();
                }
                string path = @"path of the docx";
                File.WriteAllBytes(path, documentStream.ToArray());
                // Run Word to open the document:
                System.Diagnostics.Process.Start(path);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);

            } Console.WriteLine("Press Return to terminate");
            Console.ReadLine();
        }




        public static void CopyStream(Stream source, Stream target)
        {

            if (source != null)
            {

                MemoryStream mstream = source as MemoryStream;
                if (mstream != null) mstream.WriteTo(target);
                else
                {
                    byte[] buffer = new byte[2048];
                    int length = buffer.Length, size;
                    while ((size = source.Read(buffer, 0, length)) != 0)
                        target.Write(buffer, 0, size);
                }
            }
        }

Thanks in advance for your advice, help.

I have no problem to fill the customXML , it's the selection of the building block my main problem

when I look at the file generated, and go the developer item in the word ruban, if I select the Document Template I see that my template is not attached

but in the file word\_rels\settings.xml.rels  I have the path on my template

<Relationship Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate" Target="path of the template.dotx" TargetMode="External" Id="R01f8ea2394c24745" />
