My customer gave me some Word and Powerpoint documents which specify how certain 'reports' generated by our product are supposed to look like.
That means, I need to modify those documents (replace placeholders etc.) and then I need to export them as PDF.
How would you solve this problem in C# ?
TL;DR: Editing the office document is no problem at all, but exporting that document to PDF (using Interop) allegedly causes issues when running it as a web server application. That's the whole problem here.
I agree that Interop is not suitable for document manipulation in server environment. I would approach this problem by preparing MS Word template documents with placeholders for data. Then I would use c# to load the data for the reports and merge the data with templates to get final documents (docx, pdf, xps or various image formats). There are 3rd party toolkits which make it quite easy. Here is the code used by one such toolkit needed for merging xml data with the template to get a pdf document:
XElement customers = XElement.Load("Customers.xml");
DocumentGenerator dg = new DocumentGenerator(customers);
DocumentGenerationResult result = dg.GenerateDocument("MyTemplate.docx", "MyReport.pdf");
You can of course also use free libraries and SDKs based on OpenXML but you should expect a steep learning curve, lots of debugging and lots of time invested.
Wkthmltopdf might be an option.
A completely different "report approach" could be, to save those office documents with the placeholders as mht (That's MHTML a web archive format). This could be done directly in MS Office or even programatically.
The placeholders could be easily exchanged by string search and replace. The mht files could directly be used to show the report instead of the PDF. A clear disadvantage of the mht format, is the HTML formatting. With PDF you have a clear and fix positioning.
We are using this kind of report creation. There are some flaws, but it works and the customer could edit the mht templates directly by right-click Open-With the prefered MS Office flavor.
You can use report generators, like FastReport.Net for solving your problems. It can assign different data for placeholders and also allow export to PDF.

I was hoping for a good point in the correct direction, as this is something I have never done, and googling is getting me tied in knots.
I want to create a word document (docx) from C# on a ASP.NET MVC application.
Populating a template with something like mail merge would be great.
I have spent day googling this and keep finding archived documentation.
The following examples are from 2012
https://msdn.microsoft.com/en-us/library/office/bb491088.aspx
Because you will generate documents on the server you should avoid Interop for document manipulation. You can use free libraries and SDKs based on OpenXML but this is difficult to learn and error prone.
It probably makes sense to choose one among 3rd party toolkits to get the job done quick and easy. Start by preparing MS Word template documents with placeholders for data. Then you can use c# to load the data for the reports and merge the data with templates to get final documents (docx, pdf, xps or image formats). Here is the code used by one such toolkit needed for merging data from the database with the template to get a pdf document:
IEnumerable<Customer> customers = DataAccess.GetCustomerById(15);
DocumentGenerator dg = new DocumentGenerator(customers);
DocumentGenerationResult result = dg.GenerateDocument("MyTemplate.docx", "MyReport.pdf");
You can also see these examples for more information.
Maybe Templater can be of help..
This is small library you can use to create word document on ASP.NET looking like mail merge...
Try demo http://templater.info/demo
Its a general scenario when we provide an option of attaching a file (MS .doc) to end user. This file is stored in DB as binary. When user try to access this attachment next time, we allow them to download it. Now, here I want to give a feature to user where he should be able to open this doc file on click, edit it and save it without downloading.
.doc is a binary format and not easy to work with - a library such as Aspose, as mentioned by Christian, is definitely the way to go.
However, if .DOCX is acceptable (and that's Office 2007 and higher), then you can achieve what you want in three steps:
Convert .docx to HTML
Convert Word to HTML then render HTML on webpage
Display the HTML using any rich text control of your choice
What is the best rich textarea editor for jQuery?
Finally, convert HTML back to .docx:
Convert Html to Docx in c#
You would have to "reinvent" Microsoft Office Online (look into your skydrive account). I am unsure if there are any "out of the box" libraries for that, but you could build a simple editing app by leveraging Aspose word (or some other library). But that would be far from simple.
Link to aspose: http://www.aspose.com/.net/word-component.aspx
Word will only open files that are locally stored. What you are looking for is something similar to editing items that SharePoint provides using the WebDAV interface.
You may be able to use this approach to support your requirement. You should be cautious about the security aspects of the solution unless you have fully authenticated access to the shared folder on the server.
I am not sure if a standalone MS Word Document editor exists. However, this can be done with using a combination of rich text formatting / converting tool (for example, the DevExpress ASPxHtmlEditor + Document Server):
Load binary data from a DB;
Import loaded data (MS Word content) as HTML content into the ASPxHtmlEditor;
Edit imported data via the WYSIWYG ASPxHtmlEditor;
Convert the edited HTML back to MS Word content;
Save the converted / edited MS Word content back to the DB.
I believe, it is possible to do something like this if you have such products (free or commercial analogs) in your project.
I am using SQL Server Reporting Service 2005(SSRS 2005) to export report to Excel and PDF and VS2008. But now i want an option to Export to Word also, but it is not possible in SSRS 2005 report that i came to know after googling. Here problem is that I CAN'T USE SSRS 2008 REPORT. So i thought that i will follow the steps as....
-- Export to Word
1. Export to PDF
2. Convert that PDF to Word document
Even after so much of googling i didn't got the proper answer. I told once and even telling that i can't use any third party tools so don't give me wrong path.
There are many fundamental differences between PDF and Word making the approach you want highly undesirable as a general workflow. I'll give just one example: PDF typically does not store information about document structure - sentences, paragraphs, columns, tables... All it stores is the actual text at certain locations at a page. Word of course does have those concepts.
Is it possible to do what you want? Yes, to some extent. In the general case with guesswork and approximation. If you know which information you want to convert it might be possible to search for it in the PDF file generated by SSRS and then generate a Word file out of it. However, if SSRS allows export to text, XML, RTF or any other structure based file format (however slightly structure based), you'd have a much easier time.
If you insist on doing what you suggest here, you would have to:
1) Write code to take the PDF exported from SSRS and interpret it (find the textual content you want)
2) Recreate the necessary structural information from that information (what are paragraphs, where and what are the tables, what's the formatting etc...)
3) Write that into a file Word can read (or create a new Word document directly using automation).
This would be a considerable amount of work, but you have all of the necessary information as the PDF specification is freely downloadable from the Adobe web site and it contains all of the information you need.
I need to generate a high quality report based on information in a SQL Server database, and I want very explicit control of the layout and appearance from inside C#.
I have several choices that I know of that are already being used for various other reports at our company:
1) SQL Server's built in Reporting Services
2) Adobe Forms
3) Crystal Reports
This information I need as PDF directly parallels what is already being displayed in the user's web browser as HTML, so creating a print stylesheet and converting the browser body to PDF is an option as well.
So this creates option 4:
4) JavaScript convert HTML to PDF (my preference at this time)
Does anybody have a recommendation as to which approach I should take, or even better an alternative? All the choices seem pretty horrible.
I've used iTextSharp with very good results. It is an open-source .NET port of a java library. It works really well for creating PDFs from scratch. Remember that editing PDFs will always be hacky with any library, because PDF is an output format, not a read-write format.
Provided your HTML is fairly clean (remove javascript postbacks, anchors, ...),the iText HtmlWorker can convert HTML to PDF, if you prefer that route.
HTML to PDF in using iTextSharp:
Document doc = new Document(PageSize.A4);
HTMLWorker parser = new HTMLWorker(doc);
PdfWriter.GetInstance(doc, Response.OutputStream);
Also here.
Use SSRS, it has a built in PDF rendering mode.
I have used two other PDF report libraries with great success; Active Reports and Telerik Reporting. Personally I prefer the latter when it comes to programmatic control of layout and such.
Take a look also at the DevExpress Reporting (non-free 3rd party tool):

Yes, you should use the best tools to get the best solution. The best tool in this case probably is SSRS.
But that's just looking at the capabilities of the tool.
Don't forget to look at your own capabilities!
My story: I know SQL, I know C#. (Both intermediate, I'm not a guru.)
Then I lay my hands on SSRS. And burnt them, once, twice, etc.
At the end, there was a nice result. So burning your fingers is not a wrong thing to do.
But first try to pull your html through an html to pdf converter (demo version) and see if the result it serves your needs.
Currently I'm using both:
SSRS for creating invoices, because amounts have to be transported from one page to the next
Winnovative to generate documents that only need page numbers
I would suggest using .Net ReportViewer control in local mode (no report server required). It works in both webforms and winforms. You create a client-side report (.rdlc) file (which contains all the visuals as well as placement of data fields), link it up to the ReportViewer, and supply the data (DataTable or collection of objects, as long as the fields match, it doesn't matter). In client mode it supports exporting to pdf and excel (and Word too? don't remember). By default these done by a dropdown in the control itself however you can programmatically export to any of the supported formats as well. You'll end up with a byte array you can shove into a file stream.
Basically you get most of the good parts of SSRS without all of that backend complexity. There should be a ReportViewer folder in %programFiles%\Microsoft Visual Studio 10.0\ReportViewer - but versions exist for 2005 and 2008 as well. Check out http://gotreportviewer.com/
I think the 4th option is the best. In this case you don't need to change either layout of the HTML page or a layout of PDF, if one of them has been changed.
It is also more convenient making a nice design via HTML than programmatically via C# :)
Take a look at WebToPDF.NET which is a .NET component written in C# that converts HTML to PDF. The converter supports HTML 4.01, XHTML 1.0, XHTML 1.1 and CSS 2.1 including page breaks, forms and links. It passes all W3C tests (except BIDI).
You can use Fast Report it's good tool and i has a free version
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
