I want to insert a chunk of formatted text into a Word document in VBA. Since this will be done server-side, I am not advised take these chunks from another Word document using Office Interop (link), so I presume it would be easiest to use Open XML like this <w:p><w:r><w:t>String from WriteToWordDoc method.</w:t></w:r></w:p> Sadly Application.ActiveDocument.Range.InsertXML fails. So what other quick and dirty alternatives do I have?
For the "bare necessities" see this MSDN article: https://msdn.microsoft.com/en-us/library/office/dn423225.aspx?f=255&MSPPError=-2147217396
It describes what the minimum requirements are for inserting Open XML into an open Word document. Don't worry that the discussion targets Web add-ins - the principle is the same for any API that inserts WordOpenXML into a Word document at run-time.
I may be misunderstanding where "server-side" is involved in your process, so forgive me if the following is not relevant to your situation: Note that using VBA server-side is a bad idea - Word is not designed to run in a server environment. Better would be to use the Open XML SDK both to retrieve and write the information between two Word documents.
