When using NPOI to create a Word document, how does one set a paragraph to the built-in "Heading 1" style?
Here is what I have tried in F#:
let doc = XWPFDocument()
let p = doc.CreateParagraph()
p.Style <- "Heading 1"
let r = p.CreateRun()
r.SetText("Hello, world")
When I open the generated file in Word, the line "Hello, world" is not in the Heading 1 style.
Here is what I did:
Using Word,
Create a new Blank document.
Include a paragraph that has the style(s) of interest.
Save the document to your project folder.
In code using NPOI,
Load the blank document.
Delete the contents of the document.
Write to your document, setting the paragraph style with the styleId.
Here is an example:
use fsSrc = new FileStream("blank.docx", FileMode.Open, FileAccess.Read)
let doc = XWPFDocument(fsSrc)
while doc.RemoveBodyElement(0) do ()
let p = doc.CreateParagraph()
p.Style <- "Heading1"
let r = p.CreateRun()
r.SetText("Hello, world")
Today I learned...
The default styles are not included when creating a new XWPFDocument().
The styles are identified by their styleId, not their user friendly names. The styleId for "Heading 1" is Heading1.

I'm using itext 7.2.1 and I've this situation: I have a list of letters with variable content that normally fits in one page, but occasionally can span over two pages.
My goal is to force a new blank page after the "short" letters so they start alway on odd pages. The length of text is not know in advance.
Basically I have the following code:
PdfWriter writer = new PdfWriter("letters.pdf");
Document document = new Document(new PdfDocument(writer));
List<String> letters = . . .code to retrieve letters text;
int nLetter = 0;
for (String text : letters) {
Paragraph p = new Paragraph().add(text);
doc.add(p);
nLetter++;
//now after layout of last paragraph I must ensure that
//the next paragraph starts on page (nLetter*2 + 1): how can I do this?
}
. . .
doc.close();
What is the best way to do so in iText7? I tried with custom DocumentRenderer but I haven't found a clean and working solution.
The best and simpliest way to know if your next paragraph starts on the next page of the document is to get the root renderer of your document and get current area. And it will return the area(rectangle and page) where the end of the text is located.
doc.getRenderer().getCurrentArea();
I'm working on an index in InDesign. Some of the page numbers are in bold, others are in italics or regular. During editing, somehow the first numbers of some of the bold page numbers got changed. I've figured out how to highlight those page numbers by coloring the bold numbers and recoloring the page numbers that are correct using a GREP search for bold words (\b\w+\b). What I can't figure out is how to select the "bad" page numbers that have only some numbers and make the entire "word" bold. Any ideas? It would be nice not to have to fix them manually.
I just tried this on a document and added a few numbers that were only partially bold.
I was able to fix it by doing a search for only digits with (\b\d+\b), changing all to $1. I left find format blank and change format to regular font. This changed all numbers to regular with no mixed bold and regular.
After that you can run the same find and replace again but switching format to bold. This will change all numbers to be fully bold.
It heavily depends on the text you have. If it's just one first digit that need to change, if you don't use character styles, if you have no digits in your body text, if the font you're using has the common names for styles, if ... there is a lot of 'if's, actually. I'd recommend to share a sample of your file (IDML).
So, here is the script that could do the job (if all of those "if"'s are true):
var doc = app.activeDocument;
var styles = doc.characterStyles;
// STEP 1 -- apply style1 (regular) to all regular numbers \d\d+
var style1 = styles.add();
style1.name = 'digits_regular';
style1.fontStyle = 'Regular';
app.findGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.findWhat = '\\b\\d\\d+'; // two or more digits
app.findGrepPreferences.fontStyle = 'Regular';
app.changeGrepPreferences.changeTo = '$0';
app.changeGrepPreferences.appliedCharacterStyle = style1;
doc.changeGrep();
// STEP 2 -- apply style2 (italic) to all italic numbers \d\d+
var style2 = styles.add();
style2.name = 'digits_italic';
style2.fontStyle = 'Italic';
app.findGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.findWhat = '\\b\\d\\d+';
app.findGrepPreferences.fontStyle = 'Italic';
app.changeGrepPreferences.changeTo = '$0';
app.changeGrepPreferences.appliedCharacterStyle = style2;
doc.changeGrep();
// STEP 3 -- apply style3 (bold) to all unstyled numbers
var style3 = styles.add();
style3.name = 'digits_bold';
style3.fontStyle = 'Bold';
app.findGrepPreferences = NothingEnum.nothing;
app.findGrepPreferences.findWhat = '\\b\\d\\d+';
app.findGrepPreferences.appliedCharacterStyle = styles[0]; // syle '[None]'
app.changeGrepPreferences.changeTo = '$0';
app.changeGrepPreferences.appliedCharacterStyle = style3;
doc.changeGrep();
// clean prefs
app.findGrepPreferences = NothingEnum.nothing;

Result:
Then you can remove the character styles you don't need them. But I'd recommend to use styles. They make the life easier exactly in such cases.
It's much easier to use the Find/Change interface in Indesign.
I am completely new to PDF creation including MigraDoc. I have gotten this far, which is really close to what I want for now. My question is that the text string (myMessage) that I pass to the "bodyParagraph" is up to 100 lines long, which causes three pages to be created, which is good. However the first page's Top margin is slightly greater than the second and third pages. I have no idea of why...
Basically, I am trying to create every page the same. Same header, footer and the body to take the same space regardless of the number of lines in the "bodyParagraph" content. If I have taken the completely wrong approach I would be open to suggestions.
Also, if there is a good tutorial to point me to that would be great. I can't really find anything but samples. I have learned everything from the samples, but sections, paragraph, etc is all new to me and I would like to get a better understanding of what I've done.
public static Document CreateWorkOrderPDF2(Document document, string filename, string WorkOrderHeader, string myMessage)
{
Section section = document.AddSection();
section.PageSetup.PageFormat = PageFormat.Letter;
section.PageSetup.StartingNumber = 1;
section.PageSetup.LeftMargin = 40;
//Sets the height of the top margin
section.PageSetup.TopMargin = 100;
section.PageSetup.RightMargin = 40;
section.PageSetup.BottomMargin = 40;
//MARGIN
HeaderFooter header = section.Headers.Primary;
header.Format.Font.Size = 16;
header.Format.Font.Color = Colors.DarkBlue;
MigraDoc.DocumentObjectModel.Shapes.Image headerImage = header.AddImage("../../Fonts/castorgate.regular.png");
headerImage.Width = "2cm";
Paragraph headerParagraph = section.AddParagraph();
headerParagraph = header.AddParagraph(WorkOrderHeader);
//BODY PARAGRAPH
Paragraph bodyParagraph = section.AddParagraph();
bodyParagraph = section.AddParagraph(myMessage);
bodyParagraph.Format.Font.Size = 10;
bodyParagraph.Format.Font.Color = Colors.DarkRed;
//paragraph.Format.Distancne = "3cm";
Paragraph renderDate = section.AddParagraph();
renderDate = section.AddParagraph("Work Order Generated: ");
renderDate.AddDateField();
return document;
}
The line Paragraph bodyParagraph = section.AddParagraph(); adds an empty paragraph. I assume that is the extra space on the first page.
Same issue with renderDate in the following code block.
Just remove the calls section.AddParagraph() to remove the empty paragraphs if you don't want them.
MigraDoc is much like Word and understanding sections, paragraphs, &c. in Word will also help you with MigraDoc. That knowledge along with the samples and IntelliSense should get you going.
You can use MigraDoc to create an RTF file, open the RTF in Word, and click the pilcrow to show formatting characters in Word.
Kendo UI 2015.2.805 Kendo UI Editor for Jacascript
I want to extend the kendo ui editor by adding a custom tool that will convert a user selected block that spans two or more paragraphs into block of single spaced text. This can be done by locating all interior p tags and converting them into br tags, taking care not to change the first or last tag.
My problem is working with the range object.
Getting the range is easy:
var range = editor.getRange();
The range object has a start and end container, and a start and end offset (within that container). I can access the text (without markup)
console.log(range.toString());
Oddly, other examples I have seen, including working examples, show that
console.log(range);
will dump the text, however that does not work in my project, I just get the word 'Range', which is the type of the object. This concerns me.
However, all I really need however is a start and end offset in the editor's markup (editor.value()) then I can locate and change the p's to br's.
I've read the telerik documentation and the referenced quirksmode site's explanation of html ranges, and while informative nothing shows how to locate the range withing the text (which seems pretty basic to me).
I suspect I'm overlooking something simple.
Given a range object how can I locate the start and end offset within the editor's content?
EDIT: After additional research it appears much more complex than I anticipated. It seems I must deal with the range and/or selection objects rather than directly with the editor content. Smarter minds than I came up with the range object for reasons I cannot fathom.
Here is what I have so far:
var range = letterEditor.editor.getRange();
var divSelection;
divSelection = range.cloneRange();
//cloning may be needless extra work...
//here manipulate the divSelection to how I want it.
//divSeletion is a range, not sure how to manipulate it
var sel = letterEditor.editor.getSelection()
sel.removeAllRanges();
sel.addRange(divSelection);
EDIT 2:
Based on Tim Down's Solution I came up with this simple test:
var html;
var sel = letterEditor.editor.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
html = html.replace("</p><p>", "<br/>")
var range = letterEditor.editor.getRange();
range.deleteContents();
var div = document.createElement("div");
div.innerHTML = html;
var frag = document.createDocumentFragment(), child;
while ((child = div.firstChild)) {
frag.appendChild(child);
}
range.insertNode(frag);
The first part, getting the html selection works fine, the second part also works however the editor inserts tags around all lines so the result is incorrect; extra lines including fragments of the selection.
The editor supports a view html popup which shows the editor content as html and it allows for editing the html. If I change the targeted p tags to br's I get the desired result. (The editor does support br as a default line feed vs p, but I want p's most of the time). That I can edit the html with the html viewer tool lets me know this is possible, I just need identify the selection start and end in the editor content, then a simple textual replacement via regex on the editor value would do the trick.
Edit 3:
Poking around kendo.all.max.js I discovered that pressing shift+enter creates a br instead of a p tag for the line feed. I was going to extend it to do just that as a workaround for the single-space tool. I would still like a solution to this if anyone knows, but for now I will instruct users to shift-enter for single spaced blocks of text.
This will accomplish it. Uses Tim Down's code to get html. RegEx could probably be made more efficient. 'Trick' is using split = false in insertHtml.
var sel = letterEditor.editor.getSelection();
if (sel.rangeCount) {
var container = document.createElement("div");
for (var i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
var block = container.innerHTML;
var rgx = new RegExp(/<br class="k-br">/gi);
block = block.replace(rgx, "");
rgx = new RegExp(/<\/p><p>/gi);
block = block.replace(rgx, "<br/>");
rgx = new RegExp(/<\/p>|<p>/gi);
block = block.replace(rgx, "");
letterEditor.editor.exec("insertHtml", { html: block, split: false });
}
I'm new to using NPOI XWPF and trying to create my first document, so far it's going well. The only issue I have left is trying to place text on the same line that is both left and right justified, I want it to look like:
Area: 1(Left Jstfd) Grade Level/Course: 10th Grade Reading (Right Jstfd)
Below is the code snippet I'm using, it's just pushing all the text together on the left side of the page...blah
XWPFParagraph p2 = doc.CreateParagraph();
p2.Alignment = ParagraphAlignment.LEFT;
XWPFRun r3 = p2.CreateRun();
r3.SetBold(true);
r3.FontFamily = "Times New Roman";
r3.FontSize = 12;
r3.SetText("Area: " + ah.schoolArea);
XWPFRun r4 = p2.CreateRun();
r4.SetBold(true);
r4.FontFamily = "Times New Roman";
r4.FontSize = 12;
r4.SetText("Grade Level/Course: " + ah.filterParm);
Before trying to accomplish a task in (N)POI, it's always good to realize how said task is accomplished in Microsoft Word itself. You can't simply split a paragraph half-way a line, what you do is
Add a tab stop at the end of the line
Set it to right-aligned.
Type text on the left, hit tab, type text on the right
Unfortunately, it doesn't seem XWPFParagraph exposes tabstop functionality at this point. However, XWPFParagraph is a wrapper around the CT_P class, which maps 1:1 onto the underlying Office XML format. Using reflection, we can access this private field and use it to directly add the tabstop.
Sample code:
var paragraph = document.CreateParagraph();
var memberInfo = typeof(XWPFParagraph).GetField("paragraph", BindingFlags.NonPublic | BindingFlags.Instance);
if (memberInfo == null)
{
throw new Exception("Could not retrieve CT_P from XWPFParagraph");
}
var internalParagraph = (CT_P) memberInfo.GetValue(paragraph);
CT_PPr pPr = internalParagraph.AddNewPPr();
CT_Tabs tabs = pPr.AddNewTabs();
CT_TabStop tab = tabs.AddNewTab();
tab.pos = "9000";
tab.val = ST_TabJc.right;
var run = paragraph.CreateRun();
run.SetText("Left aligned");
run.AddTab();
run = paragraph.CreateRun();
run.SetText("Right aligned");
Result:
