What is header in richtextbox format?? And how can we manipulate the rtf file.
To see how an RTF document looks in its raw form, save some text in an RTF-aware editor like wordpad, and then open it again in a plain text editor. For example, this RTF document:
Hello,
world!
becomes this when opened in plain text mode:
{\rtf1\ansi\ansicpg1252\deff0\deflang1030{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.21.2509;}\viewkind4\uc1\pard\f0\fs20 Hello,\par
\b world\b0 !\par
}
Notice that there is a lot more text in the raw version than is visible when opened in an RTF-aware editor. If you want to manipulate the RTF document using raw string operations, you have to be careful to preserve the structure of this document otherwise it may become unreadable. It would be better to use an RTF parser to modify the document to avoid accidentally breaking it.
See the v1.6 RTF specification, including the Header part.
Obviously this relates to your previous questions today: again, I suggest that instead of trying to have a single document with multiple sections, you create separate documents.

I am trying to format a hyperlink in a Rich Text Box using the Rich Text Format. I can get basic formatting working thanks to this answer, for example making text bold. However I cannot get the RTF formatted hyperlink to work. I found an example of making an RTF link here. However, when I try to put this in the Rich Text Box as seen below, it causes my application to crash. Any suggestions as to what i'm missing here?
string my_hyperlink_text = #"{\field{\*\fldinst HYPERLINK \"http://www.google.com/\"}{\fldrslt Google}}"
if (rtbControl is RichTextBox & rtbControl.Name == "name_of_control") // Making sure the control is a RichTextBox
{
RichTextBox rtb = rtbControl as RichTextBox;
rtb.Rtf = my_hyperlink_text;
}
An easy way for getting rtfs to work is to write your text in Microsoft word, copy & paste it to Wordpad and the saving it as a RTF from there.
The detour with MS Word is needed, because WordPad does not support entering links in the UI, although it handles them correctly when they come from other sources, like the clipboard. Also, MS Word creates massively bloated rtf.
The rtf file you create this way can then be opened in any text editor and can be used as a string constant in your program.
In your case, I suppose that the prefix and maybe the color table are missing and are causing the problem.
By the way: Wordpad is not much more than a wrapper around the Windows rtf control, i.e. the same control that you are using in your code.
I have collection of RTF text and I need to generate the report in word by pasting this RTF content from collection in loop. I use word template (i.e. .dotx) file as a base template file so as to generate report in structured manner. In base template file, I have some placeholder texts which needs to be replaced with the RTF content. While replacing the placeholder text with RTF content I'm facing following two issues :
maintaining the source formatting i.e. to apply format of RTF content (i.e. font, color, bold, etc.) in generated word report
pasting of RTF text in proper order with proper content
In order to maintain source formatting while copying the RTF content, I use
Range.PasteAndFormat(WdRecoveryType.wdFormatOriginalFormatting)
This ensures that while I copy the RTF content from my collection, original source formatting (i.e. as per RTF text) gets applied. There are few other methods to paste the content i.e. Paste, PasteSpecial but they don't maintain the source formatting and upon pasting, it takes the font as the default font of the base word template file. Problem using the PasteAndFormat method is, generated output it bit gibberish when report is generated using template file while generated output is proper when not generated using template file.
I have created the sample project (available at https://drive.google.com/open?id=1es1aBgewbJvQxmOAQF3FMhx3inu3keVy) which exactly reproduces the problem I face. In sample application, when you enter 1, it will generate the report without using the template file and that is the kind of final report I want. When you enter 2, it generates the report with gibberish text and I'm not able to figure out the reason for such output.
Can anyone pls help me to figure out what is the problem with the sample application code and help me to generate the report with option 2 same as the one generated with option 1?
I need to get a text that's being written by a user (in CKEditor HTML), and then add that text to a MigraDoc document, as a paragraph or whatever I need it to be.
My idea was converting the text to an MDDDL document (in memory) and add it to the document. But I don't know if there are any DLLs that permit that behaviour.
So, my question is, can someone give me pointers or advice on how I could make this happen? Should I parse the HMTL text? If so, to what should I parse it? How can I add it afterwards?
Neither PDFsharp nor MigraDoc can parse HTML, so either write your own code or try to find a third-party library (which may not exist yet).
I would probably convert the HTML directly to MigraDoc document objects in memory.
MigraDoc / PDFSharp can't do this.
But, you could use HtmlAgilityPack nuget and then use its htmlDoc.DocumentNode.Descendants() to pull out the pieces of text from html in a flat list kind of a structure, and node.ParentNode.Name to figure out the tag that the text is wrapped in. And then insert the text into your MigraDoc document with something like .AddFormattedText() and apply custom MigraDoc styles to it - i.e. if the parent tag is "strong" then apply a MigraDoc style where Font.Italic = true; etc..
I just want to save the contents of a rich textbox into a TXT file and keep everything in it in the format that it is (as far as spaces, new lines, and tabs are concerned, but I don't care if colors and fonts are lost), but they're always saved as RTF files.
Even I specify a txt file the results still look like:
({\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}} {\colortbl ;\red0\green128\blue0;\red255\green0\blue0;})
How can I make it just save the contents without those tags?
Use richTextBox1.SaveFile(path, RichTextBoxStreamType.PlainText) instead of RichTextBoxStreamType.RichText
i have a word(Office) file. this file content text and picture.
how can read this file and show in <textarea> </textarea>;
The best way to display rich content like word document on UI is through html. You can export your word document to HTML and render it to asp.net UI controls. If you prefer, textarea, you have to implement custom textarea to support images from word-html file.
Also, you can use WebBrowser control to display this word-html file instead of textarea.
I don't believe you can read this into a <textarea> as you ask. (I will watch to see if somebody else shows how, because I want to see that too...) I believe the closest result you will get is to open the document into an <iframe> with the application/msword content type. If you are looking for some flexiblity in this, wrap the space in a <div> and swap out <textarea> for <iframe> at the server when appropriate.
