I'm using PDFsharp to work with PDF documents; on the same solution I use MigraDoc to create invoice PDFs. I was wondering if I could open an existing PDF using PdfDocument and extract the information to create a MDDDL file.
The short answer: No, you cannot.
The long answer: With a lot of own code you can get it going, but not out of the box.

Using the older ReporteRs package, it looks like it was possible to specify a Word template with code like:
doc <- docx(template = "your template.docx")
Is it possible to specify a Word template using the newer officer package? It may be in the documentation but I don't see it. A workaround might be to read the file I want to use as a template, to delete all the content, and then to add new output to the empty file. I wouldn't want to try something like that though if it's possible just to specify a template.
Thanks.
Yes; you can open a connection to a docx template with doc <- read_docx(*your template file name here*).
Hi my colleague and I has been trying to get the TinyButStrong plugin openTBS to create some docx files.
We have a live system which creates some RTF files, with data from MySQL. We want to change this to docx, use openTBS. A couple of super users then in Word manage the templates.
We have a problem with creating the files, as we need to remove a line, if data isn't present.
If we in the Word template do
<w:p>[*fieldname*;magnet=w:p]*some kind of text*</w:p>
it hiddes the line if fieldname contains no data, and if if contains data, it will show the line. GREAT :-)
The problem is, that it also shows <w:p> and </w:p> when it contains data, and we don't like that.
How do we get it to stop showing these tags?
The TBS parameter ope=minv is done for thus purpose: it performs the magnet behavior but keep the field invisible (minv stands for magnet invisible).
So the solution is:
<w:p>[*fieldname*;magnet=tbs:p;ope=minv]*some kind of text*</w:p>
By the way, magnet=tbs:p is better than magnet=w:p because your template stays compatible when converted to another other format (LibreOffice).

I've created a generic handler in VS2012 using their basic template as a starting point and modified it to grab a pdf from our sqlserver. The primary code block is this:
buffer = DirectCast(rsp.ScalarValue, Byte())
context.Response.ContentType = "application/pdf"
context.Response.OutputStream.Write(buffer, 0, buffer.Length)
context.Response.Flush()
And this works fine to display the BLOB as a pdf using whichever pdf plugin is installed on any given browser.
My Question: How can I modify the handler to write Adobe PDF specific parameters to the output? Specifically I'm trying to set width='fit' such that the output PDF stream will autofit the document to the width of the popup window.
NB: Writing the BLOB to a pdf file and serving the PDF is not an option.
Thanks in advance for any advice or links
I don't think there's anything that you can do in your handler. According to that document PDF viewers can examine the URL that was used to open the PDF but there are no HTTP headers that you can set. So you'll need to modify the thing that links to your handler to have those parameters in place. Alternatively, you could build a pre-handler that HTTP redirects to your new handler with those parameters in place.
Also, that document was written in 2007 and was intended for Adobe Acrobat and Adobe Reader. Most modern browsers ship with their own internal PDF viewer these days so unless you are only targeting Adobe your efforts might be wasted.
I would like to upload a Word 2007 or greater docx file to my web server and convert the table of contents to a simple xml structure. Doing this on the desktop with traditional VBA seems like it would have been easy. Looking at the WordprocessingML XML data used to create the docx file is confusing. Is there a way (without COM) to navigate the document in more of an object-oriented fashion?
I highly recommend looking into the Open XML SDK 2.0. It's a CTP, but I've found it extremely useful in manipulating xmlx files without having to deal with COM at all. The documentation is a bit sketchy, but the key thing to look for is the DocumentFormat.OpenXml.Packaging.WordprocessingDocument class. You can pick apart the .docx document if you rename the extension to .zip and dig into the XML files there. From doing that, it looks like a Table of Contents is contained in a "Structured Document" tag and that things like the headings are in a hyperlink from there. Putzing around with it a bit, I found that something like this should work (or at least give you a starting point).
WordprocessingDocument wordDoc = WordprocessingDocument.Open(Filename, false);
SdtBlock contents = wordDoc.MainDocumentPart.Document.Descendants<SdtBlock>().First();
List<string> contentList = new List<string>();
foreach (Hyperlink section in contents.Descendants<Hyperlink>())
{
contentList.Add(section.Descendants<Text>().First().Text);
}
Here is a blog post on querying Open XML WordprocessingML documents using LINQ to XML. Using that code, you can write a query as follows:
using (WordprocessingDocument doc =
WordprocessingDocument.Open(filename, false))
{
foreach (var p in doc.MainDocumentPart.Paragraphs())
{
Console.WriteLine("Style: {0} Text: >{1}<",
p.StyleName.PadRight(16), p.Text);
foreach (var c in p.Comments())
Console.WriteLine(
" Comment Author:{0} Text:>{1}<",
c.Author, c.Text);
}
}

See XML Documents and Data as a starting point. In particular, you'll want to use LINQ to XML.
In general, you do not want to use COM in a .NET application.
I am currently working with ASP.NET MVC and I have an action method that displays few reports in the view in table format.
I have a requirement to export the same table to an Excel document at the click of a button in the View.
How can this be achieved? How would you create your Action method for this?
In your controller action you could add this:
Response.AddHeader("Content-Disposition", "filename=thefilename.xls");
Response.ContentType = "application/vnd.ms-excel";
Then just send the user to the same view. That should work.
I'm using component, called Aspose.Cells (http://www.aspose.com/categories/.net-components/aspose.cells-for-.net/).
It's not free, though the most powerful solution I've tried +)
Also, for free solutions, see: Create Excel (.XLS and .XLSX) file from C#
Get data from database using your data access methods in dot net.
Use a loop to get each record.
Now add each record in a variable one by one like this.
Name,Email,Phone,Country
John,john#john.com,+12345,USA
Ali,ali#ali.com,+54321,UAE
Naveed,naveed#naveed.com,+09876,Pakistan
use 'new line' code at the end of each row (For example '\n')
Now write above data into a file with extension .csv (example data.csv)
Now open that file in EXCEL
