I guess I have 2 questions:

1. In thedocumentation on msdn referring to Openxml and Word 2007, I noticed that there was a schema for the relationship cfChunk. Does that mean that I can use the 2003 cfChunk in Office 2007?

2. I have tried to use altChunk to add an rtf file into my .docx by manipulating the xml file I added the necessary relationship, the content type, and the code in document.xml, but the file opens as corrupt. Does altChunk not work in Microsoft Office Enterprise 2007?

I really need a way to add a .docx into another .docx file and I have tried just about everything I have found in the forums.

It is pretty easy to insert one docx inside another using Open Xml SDK v2 .  Here is roughly what I do to insert a docx file "indocument" right infront content control sdtBlock:

AlternativeFormatImportPart inDocPart = doc.MainDocumentPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML);

//Open file to be inserted and stream its contents into the part
using (FileStream stream = new FileStream(indocument, FileMode.Open))
{
      inDocPart.FeedData(stream);
}
//Create a AltChunk - <w:altChunk> and give the reltionship if linking it to the
//alternative format part we added above
AltChunk altChunk = new AltChunk();
altChunk.Id = doc.MainDocumentPart.GetIdOfPart(inDocPart);
//Insert the altChunk tag just before content control
sdtBlock.InsertBeforeSelf(altChunk);

Thank you so much I will try it. Do you know if there is any good documentation for this?

Hi thanks for the code snippet for the OpenXml sdk v2.0

I have an unanswered question I was wondering at the bottom of the code

where you have :

//Insert the altChunk tag just before content control
sdtBlock.InsertBeforeSelf(altChunk);

How can I just insert the altChunk at the bottom of the .docx or what is sdtBlock?

Here is how you can insert a file at the end of the document (after the last paragraph):

            string document = @"D:\TestDoc.docx";
            string indocument = @"D:\InDoc.docx";
            using (WordprocessingDocument doc = WordprocessingDocument.Open(document, true))
            {
                //Get the last paragraph in the document
                Paragraph paragraph = doc.MainDocumentPart.Document.Descendants<Paragraph>().Last();
                //Create a new Alternative Format part
                AlternativeFormatImportPart inDocPart = doc.MainDocumentPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML);

                //Open file to be inserted and stream its contents into the part
                using (FileStream stream = new FileStream(indocument, FileMode.Open))
                {
                    inDocPart.FeedData(stream);
                }
                //Create a AltChunk - <w:altChunk> and give the reltionship if linking it to the
                //alternative format part we added above
                AltChunk altChunk = new AltChunk();
                altChunk.Id = doc.MainDocumentPart.GetIdOfPart(inDocPart);
                //Insert the altChunk tag after the paragraph
                paragraph.InsertAfterSelf(altChunk);

                //Save the document
                doc.MainDocumentPart.Document.Save();
            }

IT WORKED!!!!!!!!!!! That's one headache out of the window!

Thank you very much vj9999.

Thanks for the code snippet. It really helped out a lot. There is one other issue involved here.

Some parts of the merged(second) document are reformatted using the style of the first document, particularly the bulleting & numbering. I tried to fix this using quite a few options. Couple of these are mentioned below,

Snippet 1 -
DocumentFormat.OpenXml.Wordprocessing.Locked locked1 = doc.MainDocumentPart.StyleDefinitionsPart.Styles.Descendants<Locked>().Last();
locked1.Val = BooleanValues.False;
doc.MainDocumentPart.Document.Save();

Snippet 2 -
AltChunkProperties properties = new AltChunkProperties();
altChunk.AltChunkProperties = properties;

MatchSource matchSource = new MatchSource();
matchSource.Val = BooleanValues.True;
altChunk.AltChunkProperties.MatchSource = matchSource;

None of these options work.

Are there any other properties which need to be set apart from the ones mentioned above?

Any help on this is highly appreciated.

Thanks,
Anand.
