Re: add image to word document header

Hello guys,

I can manipulate an existing word document  header in a SharePoint library and insert a text header to it.

However, I am having some chanllenges adding an image to a header into a word document here is my code. When I run this code I don't get to see the image in the header, all I see is x image which says image cannot be displayed.

Please assist

static void Main(string[] args)
   {

       
string siteUrl = "http://moss";

 using (SPSite spSite = new SPSite(siteUrl))
 {

 Console.WriteLine("Querying for doc.docx");
 SPList list = spSite.RootWeb.Lists["Test"];
 SPQuery query = new SPQuery();
 query.ViewFields = @"<FieldRef Name='FileLeafRef' />";
 query.Query =
 @"<Where>
 <Eq>
 <FieldRef Name='FileLeafRef' />
 <Value Type='Text'>doc.docx</Value>
 </Eq>
 </Where>";
 SPListItemCollection collection = list.GetItems(query);
 if (collection.Count != 1)
 {
 Console.WriteLine("doc.docx not found");
 Environment.Exit(0);
 }
 Console.WriteLine("Opening");
 SPFile file = collection[0].File;
 byte[] byteArray = file.OpenBinary();
 const string wordmlNamespace = "http://schemas.openxmlformats.org/wordprocessingml/2006/main";
 const string relationshipNamespace = "http://schemas.openxmlformats.org/officeDocument/2006/relationships";
 string reference = "w:headerReference";
 using (MemoryStream memStr = new MemoryStream())
 {
 memStr.Write(byteArray, 0, byteArray.Length);
 using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(memStr, true))
 {
 Document document = wordDoc.MainDocumentPart.Document;
document.MainDocumentPart.DeleteParts(document.MainDocumentPart.FooterParts);
 document.MainDocumentPart.DeleteParts(document.MainDocumentPart.HeaderParts);

AddPicHeader(wordDoc);

 }

 Console.WriteLine("Saving");
 string linkFileName = file.Item["LinkFilename"] as string;
 file.ParentFolder.Files.Add(linkFileName, memStr, true);
 }

 }
 }

I think your issue is that your adding the image to the MainDocumentPart rather than the part the image resides in (header). You'll may need to use AddNewPart<ImagePart>("image/png", null) rather than AddImagePart.
