I have been using Syncfusion DocIO for generating MS Word documents from my .net applications (winforms). So far I have dealt with plain text and it is fairly straightforward to insert text in a word document template where bookmarks serve as reference points for text insertion.
I am navigating the bookmarks using BookmarksNavigator.MoveToBookmark() . Now I need to insert an image at a bookmark but I am at a loss at how to go about it.
Please help...
Thanks.
Specifically for adding it to a bookmark :
//Move to the specified bookmark
bk.MoveToBookmark(bookmark);
//Insert the picture into the specified bookmark location
bk.DeleteBookmarkContent(true);
// we assume the text is a full pathname for an image file
// get the image file
System.Drawing.Image image = System.Drawing.Image.FromFile(sText);
IWParagraph paragraph = new WParagraph(document);
paragraph.AppendPicture(image);
bk.InsertParagraph(paragraph);
private System.Drawing.Image LoadSignature(string sFileName)
{
string sImagePath = sFileName;
System.Drawing.Image image = System.Drawing.Image.FromFile(sImagePath);
return image;
}
private void MergeSignature(WordDocument doc, string sFile, string sBalise)
{
System.Drawing.Image iSignature = LoadSignature(sFile);
WordDocument ImgDoc = new WordDocument();
ImgDoc.AddSection();
ImgDoc.Sections[0].AddParagraph().AppendPicture(iSignature);
if (iSignature != null)
{
TextSelection ts = null ;
Regex pattern = new Regex(sBalise);
ts = doc.Find(pattern);
if (ts != null)
{
doc.ReplaceFirst = true;
doc.Replace(pattern, ImgDoc, false);
}
}
iSignature.Dispose();
}
See here: https://help.syncfusion.com/file-formats/docio/working-with-mailmerge
1) You should create docx file with name "Template.docx". This file will use as template.
In your docx file create Field of type MergeField.
2) Create MergeFiled with name Image:Krishna
3)
using Syncfusion.DocIO.DLS;
using System.Drawing;
public class Source
{
public Image Krishna { get; set; } = Image.FromFile(#"C:\1.png");
}
and generating code:
public static void Generate()
{
WordDocument doc = new WordDocument("Template.docx");
Source data = new Source();
var dataTable = new MailMergeDataTable("", new Source[] { data });
doc.MailMerge.ExecuteGroup(dataTable);
doc.Save("result.docx");
doc.Close();
}

By the help of some very kind community members here I managed to programatically create a function to replace text inside content controls in a Word document using open xml. After the document is generated it removes the formatting of the text after I replace the text.
Any ideas on how I can still keep the formatting in word and remove the content control tags ?
This is my code:
using (var wordDoc = WordprocessingDocument.Open(mem, true))
{
var mainPart = wordDoc.MainDocumentPart;
ReplaceTags(mainPart, "FirstName", _firstName);
ReplaceTags(mainPart, "LastName", _lastName);
ReplaceTags(mainPart, "WorkPhoe", _workPhone);
ReplaceTags(mainPart, "JobTitle", _jobTitle);
mainPart.Document.Save();
SaveFile(mem);
}
private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
{
//grab all the tag fields
IEnumerable<SdtBlock> tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
(r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);
foreach (var field in tagFields)
{
//remove all paragraphs from the content block
field.SdtContentBlock.RemoveAllChildren<Paragraph>();
//create a new paragraph containing a run and a text element
Paragraph newParagraph = new Paragraph();
Run newRun = new Run();
Text newText = new Text(tagValue);
newRun.Append(newText);
newParagraph.Append(newRun);
//add the new paragraph to the content block
field.SdtContentBlock.Append(newParagraph);
}
}
Keeping the style is a tricky problem as there could be more than one style applied to the text you are trying to replace. What should you do in that scenario?
Assuming a simple case of one style (but potentially over many Paragraphs, Runs and Texts) you could keep the first Text element you come across per SdtBlock and place your required value in that element then delete any further Text elements from the SdtBlock. The formatting from the first Text element will then be maintained. Obviously you can apply this theory to any of the Text blocks; you don't have to necessarily use the first. The following code should show what I mean:
private static void ReplaceTags(MainDocumentPart mainPart, string tagName, string tagValue)
{
IEnumerable<SdtBlock> tagFields = mainPart.Document.Body.Descendants<SdtBlock>().Where
(r => r.SdtProperties.GetFirstChild<Tag>().Val == tagName);
foreach (var field in tagFields)
{
IEnumerable<Text> texts = field.SdtContentBlock.Descendants<Text>();
for (int i = 0; i < texts.Count(); i++)
{
Text text = texts.ElementAt(i);
if (i == 0)
{
text.Text = tagValue;
}
else
{
text.Remove();
}
}
}
}
I am trying to use the iText library with c# to capture the text portion of pdf files.
I created a pdf from excel 2013 (exported) and then copied the sample from the web of how to use itext (added the lib ref to the project).
It reads perfectly the first page but it gets garbled info after that. It is keeping part of the first page and merging the info with the next page. The commented lines is when I was trying to solve the problem, the string "thePage" is recreated inside the for loop.
Here is the code. I can email the pdf to whoever can help with this issue.
Thanks in advance
public static string ExtractTextFromPdf(string path)
{
ITextExtractionStrategy its = new iTextSharp.text.pdf.parser.LocationTextExtractionStrategy();
using (PdfReader reader = new PdfReader(path))
{
StringBuilder text = new StringBuilder();
//string[] theLines;
//theLines = new string[COLUMNS];
//string thePage;
for (int i = 1; i <= reader.NumberOfPages; i++)
{
string thePage = "";
thePage = PdfTextExtractor.GetTextFromPage(reader, i, its);
string [] theLines = thePage.Split('\n');
foreach (var theLine in theLines)
{
text.AppendLine(theLine);
}
// text.AppendLine(" ");
// Array.Clear(theLines, 0, theLines.Length);
// thePage = "";
}
return text.ToString();
}
}
A strategy object collects text data and does not know if a new page has started or not.
Thus, use a new strategy object for each page.
I'm trying to dynamically create a PowerPoint presentation. One slide has a bunch of placeholder images that need to be changed based on certain values.
My approach is to create a new ImagePart and link it to the according Blip. The image is downloaded and stored to the presentation just fine. The problem is, that there is no relationship created in slide.xml.rels file for the image, which leads to an warning about missing images and empty boxes on the slide.
Any ideas what I am doing wrong?
Thanks in advance for your help! Best wishes

So, for everyone who's experiencing a similar problem, I finally found the solution. Quite a stupid mistake. Instad of PresentationDocument document = PresentationDocument.Open(mstream, true); you have to use
using (PresentationDocument document = PresentationDocument.Open(mstream, true))
{
do your editing here
}
This answer brought me on the right way.
I have a word template and I want to create doc file from that, also I want to replace add data in place of bookmarks present in the template.
I have been able to create a doc file, but I am not able to understand, how to add data in place of bookmarks?
My code till now:
private void CreateSampleWordDocument()
{
string sourceFile = Path.Combine(Environment.CurrentDirectory, "GeneralWelcomeLetter.dotx");
string destinationFile = Path.Combine(Environment.CurrentDirectory, "Sample.docx");
try
{
File.Copy(sourceFile, destinationFile, true);
WordprocessingDocument document = WordprocessingDocument.Open(destinationFile, true);
document.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
MainDocumentPart mainPart = document.MainDocumentPart;
DocumentSettingsPart documentSettingPart1 = mainPart.DocumentSettingsPart;
AttachedTemplate attachedTemplate1 = new AttachedTemplate() { Id = "relationId1" };
documentSettingPart1.Settings.Append(attachedTemplate1);
}
catch
{
}
}
Now to add data from database in place of bookmarks?
Is it possible to bold a single word within a sentence with iTextSharp? I'm working with large paragraphs of text coming from xml, and I am trying to bold several individual words without having to break the string into individual phrases.
Eg:
document.Add(new Paragraph("this is <b>bold</b> text"));
should output...
this is bold text
As #kuujinbo pointed out there is the XMLWorker object which is where most of the new HTML parsing work is being done. But if you've just got simple commands like bold or italic you can use the native iTextSharp.text.html.simpleparser.HTMLWorker class. You could wrap it into a helper method such as:
private Paragraph CreateSimpleHtmlParagraph(String text) {
//Our return object
Paragraph p = new Paragraph();
//ParseToList requires a StreamReader instead of just text
using (StringReader sr = new StringReader(text)) {
//Parse and get a collection of elements
List<IElement> elements = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(sr, null);
foreach (IElement e in elements) {
//Add those elements to the paragraph
p.Add(e);
}
}
//Return the paragraph
return p;
}
Then instead of this:
document.Add(new Paragraph("this is <b>bold</b> text"));
You could use this:
document.Add(CreateSimpleHtmlParagraph("this is <b>bold</b> text"));
document.Add(CreateSimpleHtmlParagraph("this is <i>italic</i> text"));
document.Add(CreateSimpleHtmlParagraph("this is <b><i>bold and italic</i></b> text"));
I know that this is an old question, but I could not get the other examples here to work for me. But adding the text in Chucks with different fonts did.
//define a bold font to be used
Font boldFont = FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 12);
//add a phrase and add Chucks to it
var phrase2 = new Phrase();
phrase2.Add(new Chunk("this is "));
phrase2.Add(new Chunk("bold", boldFont));
phrase2.Add(new Chunk(" text"));
document.Add(phrase2);
Not sure how complex your Xml is, but try XMLWorker. Here's a working example with an ASP.NET HTTP handler:
<%# WebHandler Language="C#" Class="boldText" %>
using System;
using System.IO;
using System.Web;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.xml;
using iTextSharp.tool.xml;
public class boldText : IHttpHandler {
public void ProcessRequest (HttpContext context) {
HttpResponse Response = context.Response;
Response.ContentType = "application/pdf";
StringReader xmlSnippet = new StringReader(
"<p>This is <b>bold</b> text</p>"
);
using (Document document = new Document()) {
PdfWriter writer = PdfWriter.GetInstance(
document, Response.OutputStream
);
document.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(
writer, document, xmlSnippet
);
}
}
public bool IsReusable { get { return false; } }
}
You may have to pre-process your Xml before sending it to XMLWorker. (notice the snippet is a bit different from yours) Support for parsing HTML/Xml was released relatively recently, so your mileage may vary.
Here is another XMLWorker example that uses a different overload of ParseHtml and returns a Phrase instead of writing it directly to the document.
private static Phrase CreateSimpleHtmlParagraph(String text)
{
var p = new Phrase();
var mh = new MyElementHandler();
using (TextReader sr = new StringReader("<html><body><p>" + text + "</p></body></html>"))
{
XMLWorkerHelper.GetInstance().ParseXHtml(mh, sr);
}
foreach (var element in mh.elements)
{
foreach (var chunk in element.Chunks)
{
p.Add(chunk);
}
}
return p;
}
private class MyElementHandler : IElementHandler
{
public List<IElement> elements = new List<IElement>();
public void Add(IWritable w)
{
if (w is iTextSharp.tool.xml.pipeline.WritableElement)
{
elements.AddRange(((iTextSharp.tool.xml.pipeline.WritableElement)w).Elements());
}
}
}
