[VSTO V3 / Office 2007] Data Binding an Image Content Control

• nad22

  Hello Cindy,

  Here is the code I'm using:

  Word.ContentControlListEntries CommerciauxDropDownList = (Word.ContentControlListEntries)ContentControl.DropdownListEntries;

  foreach (Word.ContentControlListEntry entry in CommerciauxDropDownList)

  {

  if (entry.Text == ContentControl.Range.Text)

  {

  String SelectedId = entry.Value;

  ImageUrl = GetImageUrlForUserId(SelectedId);

  }

  }

  Image image = null;

  HttpWebRequest httpRequest = WebRequest.Create(ImageUrl) as HttpWebRequest;

  httpRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;

  HttpWebResponse httpResponse = httpRequest.GetResponse() as HttpWebResponse;

  using (Stream stream = httpResponse.GetResponseStream())

  {

  image = new Bitmap(stream);

  }

  string ImageText = System.Convert.ToBase64String(ConvertImageToByteArray(image));

  XmlDocument doc = new XmlDocument();

  XmlNode declarationNode = doc.CreateNode(XmlNodeType.XmlDeclaration, String.Empty, String.Empty);

  doc.AppendChild(declarationNode);

  XmlElement imageElement = doc.CreateElement("Image");

  XmlText imageElementValue = doc.CreateTextNode(ImageText);

  doc.AppendChild(imageElement);

  doc.LastChild.AppendChild(imageElementValue);

  object ImageControl = 4;

  Word.ContentControl ImageCommercialControl = this.ContentControls.get_Item(ref ImageControl);

  Office.CustomXMLPart customXmlPart = this.CustomXMLParts.Add(doc.InnerXml, System.Type.Missing);

  try

  {

  ImageCommercialControl.XMLMapping.SetMapping("/Image", String.Empty, customXmlPart);

  }

  catch (Exception)

  { }

  ImageText contains my image converted into base 64.

  All is working fine except that I get an exception (the one I talked you before) on the last line (in the try block)

  Any ideas

  Thanks !

  A rich text box control is not the same as an image control :-)

  I tested the binding yesterday, so I know it's "allowed" by the Word object model. I inserted an image (or picture, whatever it's labelled in the UI) control. I then did an XMLMapping (as described in the article I pointed you at in a reply, yesterday) to a CustomPart I appended to the document.

  When I loaded a picture into the control in the UI, the base-64 binary code appeared in the CustomPart. No problems.

  What I didn't test was putting a different picture into the CustomPart, primarily because my skills don't extend (yet) to that kind of thing. I come from the Word OM side :-)

  Well I know that it's allowed but in my case, it doesn't work...

  Tomorrow, I will show you my code: maybe I've done an error in it..

  Thanks Cindy !

  Another way to bind to a picture content control is to store the image to a temp file and then use addPicture, as in the following snippet of code.

  System.Drawing.Image image = /*Get the image */;
  private global::System.Object missing = global::System.Type.Missing;
  Word.ContentControl pictureContentControl = /* Get the picture content control */;
  
  string tempImageFileName = Path.GetTempFileName();
  image.Save(tempImageFileName);
  Word.InlineShapes shapes = pictureContentControl.GetRange().InlineShapes;
  while (shapes.Count > 0)
  {
  shapes[1].Delete();
  }
  pictureContentControl.GetRange().InlineShapes.AddPicture(tempImageFileName, ref missing, ref missing, ref missing);
  File.Delete(tempImageFileName);
