I need to render pdf file in a webbrowser then highlight some words on it.
How can i do it? any sure 3rd party dll that i can use for this?
Thank,
Jepe
I am using "URL Parameters" as in PDF Open Parameters to get to a certain PDF Page or bookmark. There is something for highlighting too, but not searching and highlighting AFAIK. I also do have some issue (see Fragment lost ) using it with the WinForm WebBrowser control, nevertheless I find the approach useful.

Background
I am working on a WPF windows application and I want add embedded PDF viewer with only basic functionalities including PDF view, text search and page navigation.
I tried embedded Internet Explorer and Adobe PDF Reader installed method (this way ) but this method is not suitable for our requirement as Adobe PDF Reader has too may external links which can not be allowed because of the security reasons of the application.
Therefore, I am trying to use moonpdf library. This library works fine with our requirements but the only problem is there is no text search functionality in this library. (I think it shows PDF as images)
Then, I have download moonpdf source code and realized that moonpdf is using libmupdf.dll wrapping to c#.
I can modify the moonpdf source code and mupdf source code for our requirement if needed.
My Question
Is there any text search functionalities in mupdf? if so how can I use it?
In the basic mupdf library, there are several functions for searching for text. These work by searching a page for a text string, in a few different variants, and returns the area for all hits of the given text. You need to iterate over the pages yourself (in order to do forward or reverse search).
fz_quad hits[1000];
count = fz_search_page(ctx, page, needle, hits, nelem(hits));
That said, I do not know how or even if "moonpdf" has wrapped these functions.
You can certainly extract the text from a document, the MuPDF library will do that. I believe it's up to you to apply your own search criteria after that. I'm afraid I'm not expert enough to answer the 'how to' part of it though. I imagine one of the mutool examples would be helpful here though. I'll see if I can get one of the developers to answer.
I'm writing a document view and I'd like to use the capabilities of the WebBrowser control for some file formats (pdf, e-mail).
Now I have the problem, that for every file format that is unknown to the WebBrowser control, it offers to download the file.
So the question is: How to find out what file formats (file extensions) can be displayed by the browser, so that I can display a message to the user that the current fileformat is not supported for displaying instead of getting a "Do you want to download" dialog box.
If I was you I wouldn't use a WebBrowser control for following reasons:
WebBrowser is just a wrapper around IE engine. It uses old version of IE by default, so it can have troubles displaying correctly HTML documents with basic CSS styling. It can be forced to use newer versions of IE or even other engines, but it takes some effort.
WebBrowser control purpose is to display and navigate throught web pages. And navigating is essentially downloading. I believe it's gonna be hard if not impossible to prevent WebBrowser from downloading files. I believe one way you can do it is by modifying html files like this: Remove hyperlink but keep text? Also you would probably want to prevent context menu from openning.
WebBrowser control is capable of displaying PDF as described here Displaying a PDF in a WPF Application Not Working - WebBrowser or Adobe Control But I have no idea how would you prevent following the links placed in pdf
Instead of using WebBrowser I suggest you to use one of many royalty-free PDF viewing controls and convert your html documents to PDF. I believe suggested approach will take you less time and will be more robust
How to load a pdf from desktop to tab control using Aspose.pdf package?
I donot see any document load functions in the package. I am new to this.
I am using a tab control in a C# form to load the document and then search for words inside the pdf.
Aspose.Pdf is an API. Unfortunately, it does not have any UI control which you can place in tab or any other WinForms control.
One solution could be to convert each page to image and show the images in control.
But, if you want to search and highlight text within control and want the text and other objects selectable and scrollable, just like Adobe does, wait for any other member to suggest an alternate.

i need to know the ways of embedding ms word with limited controls in winform . and also i want to insert some headers and footers in to the ms word. Found some articles which depicts only embedding the controls inside the winform . So my question is how to generate a document file and limit the controls of msword inside the winform . Anyone help me.
I don't believe this is possible.
What you could do however would be place a rich text field onto the screen and save the content into a .doc format - which you could make available for download or submission.
EDIT: question referrred to winforms. This can be done use standard rtf in the rich text box.

I have a requirement to display word document in ASP.NET form. Also, the original word format has to be retained. In a nutshell i have to embed a word document in a web form programatically. Can someone please help.
If all the clients that are browsing the site are going to have Word installed and use Internet Explorer, you could embed it with an ActiveX object. If these requirements are not met you might need to convert it to some more standard format that a browser is capable of displaying such as a jpeg image. You may also look at this option.
There are html embed tag options to embed pdfs into the html page. So probably you need to convert the doc into pdf before.

This works for me. But may need newer versions of Adobe Reader.
