how to write dll file to access pdf

Hi i'm new programming and i have written few application to access pdf content by using some dll files, but now my question is how can we write our own dll to access the pdf files. I know it's a big process but i'm very much interested to learn about this. any one please help me.
You can start by reading the PDF specification (warning 32MB behind this link) in order to understand how the PDF file format is implemented. This is necessary if you want to be able to parse it and extract the information you are interested in.
In the meantime (as this reading might occupy you during a certain amount of time) if you have pressing project deadlines you probably want to use an existing library such as iTextSharp.
I know it's a big process but i'm very much interested to learn about this.
That's true. I'd like to suggest to study some open source APIs (iTextSharp) and PDF SDK.

How can I convert PDF to doc without microsoft.office.interop?

I need to convert PDF files into .doc files using C#. The computer has no file system though it doesn't have Office installed. Any good ideas how I can approach this? I did some research and most of people use the interop services.
You need to understand that PDF is not really implemented as a single document format.
If your PDF docs are created by rendering text to a PDF file, then direct PDF conversion is not only possible, but can be very good (reliable).
If the source of your PDF is either a scanner or fax (essentially a scanner...) then what you have is a document with an "picture" of text. This scenario is more difficult to deal with. If you open up the markup for this there is no 'text' to be converted. In this situation you have to deal with some manner of OCR (optical character recognition) which is less reliable due to a variety of issues.
If you have the option of intercepting the data before it is rendered to PDF (say like in SSRS or Crystal) then it would be better for you to bypass the PDF stage and move your data to a Word document.
If you are constrained to receiving faxes and then needing to interpret their content, prepare for OCR hell. It has been a while since I was there, so I hope that it has gotten better.
Even with out office installed on your machine, you have access (with Visual Studios) to the Office developer toolkit which will allow you build documents to be distributed in the Word formats.(.doc/.docx).
An option/idea may be to convert the PDF to Html, which can be opened in Word?
use aspose pdf kit to conver pdf to text and then text to doc using filestream or aspose doc

Open PDF and print to PDF programmatically C#

I am developing an application that is able to open and display PDFs after I open them and print them to another PDF using CutePDF, but the originals are not viewable.
I am looking for a way to programmatically open a PDF file, and print to another PDF file (not necessarily using CutePDF, just printing to another PDF is the desired functionality).
This will be integrated into a C# .NET project. Are there any suggestions how to go about doing this?
Thanks.
You could use Office Interop and generate the PDF, when you say "print to another pdf", I imagine you mean just generate? Or are you saying spool them to a pdf print driver that essentially will just create a PDF to be saved.
Use iText, which is available in Java and C# versions. I have used the Java version successfully. I recommend the iText in Action book to help you get up to speed with iText faster. The book discusses only the Java API, but I imagine you will be able to learn the principles of iText from the book and then figure out the minor differences for the C# version.
To implement this you can use PDFFlow library for generating PDF files from C#. It has easy fluent syntax and many features.
Here are many examples of real complex PDF documents: examples
Good luck :)

How to convert PDF to Excel in C#?

I want to read tables which are in a PDF document and I want to store these values in a Database.
What I have found so far through searching the web:
Read text from PDF using abcpdf .net, which is freeware available. But it's not right solution because I want to read the tables.
Convert PDF document into Excel/Word. Tables will come in the target document as it is. Word conversion is possible by using EasyPDF Converter which is third party tool which is much cheaper than the other solution available in other tool which converts PDF into Excel.
But I am looking for any other solution/API classes which can convert PDF into Excel.
There are 2 possible solutions
a) Cometdocs makes a free online conversion from PDF to XLS surprisingly good and send for your email the result file.
b) Cognview is a comertial shareware that converts PDF to XLS. There is OCR and text version. I didn't use personally, but they have good recomendations.
If you are looking to upload your data into a database, converting your PDFs to CSV is probably the safest option. The PDFTables API will allow you to do this with C#, converting as many PDFs at once as necessary. https://pdftables.com/pdf-to-excel-api#csharp
You can try to use Quablo, a PDF table extractor available at this web page (link updated/corrected).

Inserting a Word document content (with formatting) in a RDLC report using C#

I'm creating a RDLC report in C#. Is it possible to insert the content of a Word 2003 document (with formatting) in it (either in design time or programmatically) before exporting to PDF. The final result will be a PDF file containing the initial report (fields from database) and the Word document content following it.
Why this? I need to give the user the possibility to fill a form, attach a word document and export the all to PDF as I described earlier (ASP.NET). I don't have Word installed on the server so I can't Interact with its COM objects.
Thank you.
Which format does the word document use? If it's .docx, you can try going with the Open XML SDK from Microsoft.
Not sure about how to import the formatting.
This question was asked a long time ago, so I doubt this answer will be of much use to the OP, but if someone else stumbles across this as I did...
...I would think it should be fairly easy using a 3rd party component to convert the doc to an image and then use that in the RDLC without much hassle at all.
