I am using PDFium to load a PDF on my Windows-Form via Visual Basic .NET. The PDF contains form fields. There is a Windows-Forms-Button that allows me to save the PDF on hard disk.
Is it possible to read the entered values ON the PDF with PDFium once the save button is clicked?
Ideas based on Visual C# .Net are also welcome.
Thanks in advance.
This functionality is not present in the original Pdfium engine. But the vendor says that this ability will be provided in the next release of Pdfium.Net SDK which is expected soon.

I'm trying to make my program have the ability to display a Microsoft Word file on a form but not having any luck in doing so. I want to be able to open the file and display it on the form as a Read-Only. So basically just display it's contents. Various users on the web have recommended displaying files in the WebBrowser control (under toolbox). I have tried this but failed to get it working. My end goal is to be able to annotate on top of the web browser (or something of similar manner) and subsequently save the annotations along with the opened file.
I'm not that experienced in the C# language too so any help on how to achieve my problem would be greatly appreciated.
You need a DOCX viewer control. My company recently gave away our multi-format WinForms viewer control as a free product - XtremeDocumentStudio .NET Free. It can display DOCX and is available on NuGet. It does not require a Web Browser control for embedding an online viewer or Word software installed locally.

There are some good links that might help you.
First, you will find a closely related or similar question here
And in that conversation someone posted the following link which is about how to build a user control for displaying Word documents in a webbrowser control.
I also found another article here about how to integrate Excel in a Windows Form application using WebBrowser. But Excel is used as an example and you may be able to adapt it to Word.
im needing to create a form in my C# project that just allows the user to view the pdf.
i have a way to open the pdf and read it but i need to disable features like printing, saving, highlighting, copy/pasting while maintaining the ability to search in the document
they should really just be able to open the document, read it,search for words in the document, close it
any help would be great
thanks in advanced
You could use Ghostscript to convert PDF to images and then show the images on your form or you could rasterize your PDF directly to the screen.
To use Ghostscript from .NET you can take a look at the Ghostscript.NET library (managed wrapper around the Ghostscript library).
Ghostscript Viewer C# sample that rasterizes PDF directly to the screen can be found here: https://github.com/jhabjan/Ghostscript.NET/tree/master/Ghostscript.NET.Viewer
To search for the text inside the pdf you can use iTextSharp
(Disclaimer I worked on this component at Software Siglo XXI)
If you don't want to mess with Ghostscript API and need a quick working solution to visualise the documents, you could use ImageZoom Viewer .NET. It's available for both 32 and 64 bit and is very cheap and effective. I'd recommend you to try it since it's a very fancy and fast. You can browse, scroll and print the pages from the viewer.
You can take a look here: http://softwaresigloxxi.com/ImageZoom.html
This is for quick browsing and reading. Then, when you want to use text operations, you could let the user to use Adobe Reader, launching the PDF from there.
I want to show a pdf page in the picturebox. Is it possible to do that? if not is there any other way out where i can show the pdf page inside the windows form in visual studio?
Thanks
No. A PictureBox can only display a System.Drawing.Image, which a PDF is not.
Instead, you should be searching for a Winforms PDF viewer.
.NET open PDF in winform without external dependencies
You can do that by using Ghostscript.NET (Ghostscript library wrapper for .NET).
Take a look at this blog: How to use Ghostscript.NET library to render PDF's directly to the screen
You can download Ghostscript.NET from here: https://ghostscriptnet.codeplex.com/
I'm using C# 2005 as a programming platform. I want to have a program reading pdf file and output the content in picturebox properties. Can anyone help me on how could i do this?
You can't render PDF in a PictureBox. Picture boxes are for displaying pictures. So if you want to render a PDF file inside a picture box you will have to first convert it to, well, a picture. There are some commercial products such as ABC PDF that would allow you to do this conversion.
Another possibility is to use the Adobe Reader ActiveX control which you could host in your WinForms application and directly show the PDF file as is.
There are some opensource libraries out there. Choose one of the below:
sharpPDF: http://sharppdf.sourceforge.net/
PDFjet: http://pdfjet.com/os/edition.html
PDF Clown: http://sourceforge.net/projects/clown/
You can get the content of the PDF file using on of these libraries. About showing it on your form etc., I'd suggest examining the samples of these libraries.
I have a pdf file which I want to open in a Windows Forms Application and perform following tasks-
View the pdf document
Zoom +/- document
Search Text
Highlight a specific text
Show it in a listbox/dropdown
select those words and highlight in pdf
Remove selection/Highlight.
I have tried using certain libraries like pdfSharp/iTextSharp even Acrobat Reader OCX control.
Its really bugging me..is there any help??
I'd suggest looking at some means of converting the PDF if you don't have a direct need to edit it. Even then, it may be easier to convert to a different form, make changes, and then convert back. PDF is a form of PostScript, which makes it powerful, but also makes it a mess to deal with and my personal preference is to skip that headache. Not always avoidable (had a lot of fun creating Thai support in PDF print#home ticket creation once without bloating the document beyond unusable), but highly recommended where possible.
Anyways, there are a variety of PDF conversion libraries out there, some of which may be available for .NET. Worst case, you may need to create a managed C++ layer to allow your C# code to access them.
Doesn't acrobat reader OCX already have all those features ? What exactly doesnt the OCX do that you need to do in your code ?
You might try contacting Adobe and getting their full SDK for PDF. It might have controls which you can use to solve your problem.
Come to think of it , is there even an SDK for PDF from Adobe ?
You have not mentioned your preference of using Free or Commercial PDF Viewer option. If you are open to use Commercial PSF viewer, you may evaluate SyncFusion PDF Viewer control, Telerik PDF Viewer, Dynamic PDF Viewer or TallComponents. I have checked feature set and all seem to have features you are looking for. I do not represent or promote any of these SDKs, I have used TallComponents and Dynamic PDF for PDF manipulation and both have excellent support, I would say PDF Veterans in .NET space.
