How to convert Word document created from template by OpenXML into MemoryStream?


How to convert Word document created from template by OpenXML into MemoryStream?

To fix the issue you can do Found answer which works without saving to intermediate temp file. Trick is to open template for editing, use accessible stream, change document type from template to document, and return this stream.
code :
public static MemoryStream GetWordDocumentStreamFromTemplate()
{
    var templatePath = AppDomain.CurrentDomain.BaseDirectory + "Controllers\\" + templateFileName;
    var memoryStream = new MemoryStream();

    using (var fileStream = new FileStream(templatePath, FileMode.Open, FileAccess.Read))
        fileStream.CopyTo(memoryStream);

    using (var document = WordprocessingDocument.Open(memoryStream, true))
    {
        document.ChangeDocumentType(WordprocessingDocumentType.Document); // change from template to document

        var body = document.MainDocumentPart.Document.Body;

        //add some text 
        Paragraph paraHeader = body.AppendChild(new Paragraph());
        Run run = paraHeader.AppendChild(new Run());
        run.AppendChild(new Text("This is body text"));

        document.Close();
    }

    memoryStream.Position = 0; //let's rewind it
    return memoryStream;
}

To fix this issue Are you referring to the OpenXml SDK? Unfortunately, as of OpenXml SDK 2.0, there's no SaveAs method. You'll need to:
Make a temporary copy of your template file, naming it whatever you want. Perform your OpenXml changes on the above file. Save the appropriate sections (ie. using the .myWordDocument.MainDocumentPart.Document.Save() method for the main content or someHeaderPart.Header.Save() method for a particular header).

help you fix your problem Every Word document has a ThisDocument object. If you write VBA code which uses ThisDocument, that object always points to the ThisDocument object in the same file as your code. ActiveDocument, on the other hand, always points to the document that is active in Word, that is, the one that is visible in the Word window at the moment. If possible, try to avoid using ActiveDocument since it can point to a different document than what you think.
In order to access a Document object other than the one your code is in, you cannot use ThisDocument, so instead you create a reference to the other document:
code :
Option Explicit

Sub FindOtherDocument()
    Dim oOtherDocument As Document
    Set oOtherDocument = Application.Documents("Filled.docx")

    Call MsgBox("This is the name of the file which oOtherDocument points to: " & oOtherDocument.FullName)
End Sub

Does that help OpenXmlPowerTools ignores headers and footers when converting a docx-document to HTML, so they won't show up in the resulting HTML (you can browse the source code on github).
Perhaps it's because the concept of a 'page' doesn't apply to HTML, so there's no obvious equivalent to a document header.

hope this fix your issue The sample code below (which is unit-tested and works) does what you are trying to achieve. It is based on the following interpretation of the question and assumptions:
"Control place holders" means "Rich Text content controls", which are called block-level structured document tags (SDTs) in Open XML lingo and are thus represented by the SdtBlock class in the Open XML SDK. The content controls have tags, meaning the relevant w:sdt elements have grandchild elements like . Those tags are used to link the data received from the REST service to the content controls. The data is provided as a Dictionary, mapping tag values to the content control text (data).
code :
public class ContentControlWriter
{
    private readonly IDictionary<string, string> _contentMap;

    /// <summary>
    /// Initializes a new ContentControlWriter instance.
    /// </summary>
    /// <param name="contentMap">The mapping of content control tags to content control texts.
    /// </param>
    public ContentControlWriter(IDictionary<string, string> contentMap)
    {
        _contentMap = contentMap;
    }

    /// <summary>
    /// Transforms the given WordprocessingDocument by setting the content
    /// of relevant block-level content controls.
    /// </summary>
    /// <param name="wordDocument">The WordprocessingDocument to be transformed.</param>
    public void WriteContentControls(WordprocessingDocument wordDocument)
    {
        MainDocumentPart part = wordDocument.MainDocumentPart;
        part.Document = (Document) TransformDocument(part.Document);
    }

    private object TransformDocument(OpenXmlElement element)
    {
        if (element is SdtBlock sdt)
        {
            string tagValue = GetTagValue(sdt);
            if (_contentMap.TryGetValue(tagValue, out string text))
            {
                return TransformSdtBlock(sdt, text);
            }
        }

        return Transform(element, TransformDocument);
    }

    private static object TransformSdtBlock(OpenXmlElement element, string text)
    {
        return element is SdtContentBlock
            ? new SdtContentBlock(new Paragraph(new Run(new Text(text))))
            : Transform(element, e => TransformSdtBlock(e, text));
    }

    private static string GetTagValue(SdtElement sdt) => sdt
        .Descendants<Tag>()
        .Select(tag => tag.Val.Value)
        .FirstOrDefault();

    private static T Transform<T>(T element, Func<OpenXmlElement, object> transformation)
        where T : OpenXmlElement
    {
        var transformedElement = (T) element.CloneNode(false);
        transformedElement.Append(element.Elements().Select(e => (OpenXmlElement) transformation(e)));
        return transformedElement;
    }
}

should help you out this is a pretty old question but I think it's worth answering anyway since this seems to come up a lot.
I also used the above sample and it works well, except that cx and cy are hard-coded and distort the image.
