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'm looking into this concept for creating AR in Unity using PDF content:
Have a picture of an object as AR target, then a command to search through a PDF database for the PDF file that contains the same/similar picture, and finally to overlay the text content in that PDF on my initial object.
From your experience, do you know if this can be achievable somehow in Unity currently?
My findings for now are that there are PDF reader plugins for Unity, that you can display PDF files in a browser (Application.OpenURL) or resorting to the PDF-image format conversion. But haven't found much on search features inside PDFs (text or image search).
Instead of searching for a PDF file that contains the same picture used as AR target, maybe search for a unique "text" and get the PDF where that string is located?

https://askubuntu.com/questions/41829/how-can-i-search-for-files-in-unity
And would it be possible to pull out the text content in the PDF and display it as overlay while target detection?
Can you also advise on trainings I could take that'll be helpful for the above? Or propose alternatives?
Thank you.
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.
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 am looking for a free open source .Net based (prefer C#) pdf driver. Any idea where I can download one?
Pdf Creator
PDFCreator easily creates PDFs from any Windows program. Use it like a printer in Word, StarCalc or any other Windows application.
If you need to use created PDF file inside of your C# application, then the easiest way is to generate PDF inside this application. Then you don't need to monitor a temp folder for a new file created.
To generate PDF inside of your application you will need a PDF-generating library for C#.
For example, PDFFlow library. You can generate all the elements of PDF document (text element, paragraph, image, inline image, line, table, page number, header/footer, etc...), so you can construct "any kind of document", as you said.
Hope, this idea will help.
