I have got an application that is supposed to send a formatted document to a printer with some barcodes.
I've made other applications that work with printers and print directly through the printserver by sending a xps file, so I thought I would try to see if I could make a .xps file, change the text and be done with it, however every article I can find on the net has to do with creating xps files and not changing them. I feel like it should be possible, and it would be nice not to have to resort to installing Office on the server and print through there. Then I might as well use Open XML and a .docx file.
It is very simple. Let's say I want to change the text INCNUMMER in a .xps file to "testing123". How would I go about that?
I have tried the whole unzip, open the xml, find the text, edit, rezip but I'm afraid there's too much about the .xps format I don't understand to make that work.
Best regards, Kaspar.
As you already know, an XPS file is just a ZIP archive containing a number of files and folders that have particular names and a defined structure.
At the root level there is a Documents folder which will typically contain just a single document folder named 1. Inside that is a Pages folder containing one or more .fpage files: these define the content of each page in the document.
Documents
1
Pages
1.fpage
2.fpage
etc
If you open up these .fpage files in a text editor you will see that they are just XML files. Each page is typically represented by a <Canvas> element that contains multiple <Path> and <Glyphs> elements (text is represented by the latter). However, even though <Glyphs> elements do have a UnicodeString attribute the value of that attribute cannot be changed in isolation.
Each <Glyphs> element also has an Indices attribute. If you remove this attribute altogether and change the UnicodeString attribute at the same time, this almost works. However, you will probably find that when viewing the file in the XPS Viewer application certain characters in the text are replaced by question mark symbols.
Font glyphs are embedded in the XPS file (odttf files in the Resources folder), and the software that generated the XPS file will only embed glyphs that are used in the source document. For example, this means that (for a given font) if you did not use the letter "A" in the source document, then the glyph for that letter will not be written to the resources of the XPS file. Hence if you change the UnicodeString attribute to include a letter "A" then that character will display as a question mark in the viewer because it has no glyph resource that tells it how that character must be drawn.
If you have control over the source document (the one that later gets converted to XPS) then I suppose you could include a piece of text containing all of the characters that you are likely to use, and set its colour to white so that it doesn't print, but I'm not sure whether the XPS printer driver would strip that text out anyway. If it didn't then you could probably do something like this:
Open the relevant .fpage XML file
Search all UnicodeString attributes of <Glyphs> elements to find the text you want
Replace that text with something else
Remove the Indices attribute from the changed <Glyphs> elements
Save the updated XML back to the file
Re-zip then change the extension from ZIP to XPS

I have been trying to insert a docx file contents into crystal reports. (In Crystal Reports if I insert OLE object and select a docx file, program imports only the used part of the word file, not the whole page.)
I have searched to convert Word document to image, but all I found was about getting a whole page or a specific image in a page. In my case I can have text and also line objects and maybe some graphic files in maybe 6 - 7 paragraphs. And only used part of the page(6 - 7 paragraphs) should be my image file.
Our customers are using this Word files as a header of the report. For now the only way I can do is to have screen shoot of the design. And it doesn't always look good. Is there a way to get this part as image?
Note: I can't use directly doc file in crystal reports, I need to have the data in SQL database. So it has to be graphic file.
You may find the Selection.CopyAsPicture method which works the same way as the Copy method. Basically you need to select the required content in a Word Document and then use this method to take a picture of selected content and keep it in a memory for further usage. For example, the following example copies the contents of the active document as a picture and pastes it as a picture at the end of the document:
Sub CopyPasteAsPicture()
ActiveDocument.Content.Select
With Selection
.CopyAsPicture
.Collapse Direction:=wdCollapseEnd
.PasteSpecial DataType:=wdPasteMetafilePicture
End With
End Sub
In C# you could use the same properties and methods, the Word object model is common for all kind of applications.
I am trying to make a word document in an asp.Net MVC application using OpenXML template document .
The main challenges for me are
How can i create a word document as an OpenXML template? In my word
document i have some paragraphs of texts and in every paragraphs i
have to fill information from data base like in word file there are
instances of text like
etc and these should be filled with actual data. But
i dont know how can i convert a normal word document as a OpenXML
template file .
How can i fill the values with data from db ? If i have a model say WordModel in hand with filled values of properties FirstName TotalAmount AmountUnit TotalCopies etc then how can i fill the details to template and allow user to download the file ?
What you want to do is called Mail Merge and means populating word documents that act as templates with your application data. There are some existing (commercial) solutions out there, but if you want to do it yourself using Open XML SDK, you need to set up some kind of tagging mechanism that you will use to tag certain parts of document where you want the data/text from the database should be placed. For Word documents you have the following options: Bookmarks, Content Controls, Merge Fields, or special text (<% FirstName %>). I would personally go with Content Controls as they offer the best user experience and they are pretty easy to parse and replace. So the templates would be ordinary word documents containing these tags and then you could use Open XML SDK to parse these templates, search the tags in them and replace them with your application data according to the tag's name/code/title. This a very abstract, high level picture of a mail merge processor. Of course system like this is not easy to implement and also note that using Open XML requires some learning. There was a similar question answered, but you can probably find many more - just google.
I am developing a MS Word add-in using c#. The code processes some very large input file and converts it to a word document. I am able to generate data and store it in heading 1, 2, ... normal etc styles.
Now I also want to store some hidden text (containing some self-generated information) with each of these paragraphs. This hidden text should by no means be visible to someone who opens this file in MSWord. But this hidden text must be retrievable to convert this word file back to the original file. Is it possible to insert some hidden fields with each paragraph (and I want to have multiple such fields - say about 4 to 5).
I am using OpenXml to create the word file.
I am very anxiously looking for some solution. Or if it is not possible to do so, then I must look into some altogether different solution.
I need to generate a PDF based on some user inputs. The output PDF have some images, tables and texts. I think that Itext is not user friendly for programmatically generate this report.
Since the report I need to generate is quite complicated, I was wondering if it is possible to create a template PDF and then load -> search -> replace the strings/images I want.
The template PDF can be a tagged pdf.
Is it possible to do that?
Is it the best approach?
EDIT: I´m using WPF + MVVM + .Net 3.5
Replacing text within a PDF file is not simple. The PDF fileformat uses a dictionary at the file end where elements are listet with their byte offset within the file, also some elements have a field where they give their own length given in bytes. If these offsets are not met, the reader will probably report a broken pdf.
You should have a look at reporting as it is made for these tasks:

You can create a template with the report designer, set your data and export it to pdf.
How to embed a word document into another word document via OpenXML SDK, but showing content, not an icon of word? Such, as we do it manually in word: Insert object from file -> WITHOUT checking "Dispaly as icon"?
I've found this article, but it uses an icon. I've also tried to use OpenXML SDK Productivity Tool, but shows only generated binary data.
EDITED:
I use the following code:
DrawAspect = OleDrawAspectValues.Content
and then i add image part:
var imagePart = mainDocumentPart.AddNewPart<ImagePart>("image/x-emf", imagePartId);
GenerateImagePart(imagePart);
But my image part - is just an array of bytes of word's icon.
So, in this case happens the following: when i open generated document, it shows embedded document as an icon, but when i double click this embedded document, edit it and save changes, the embedded document is shown as a content, so maybe it's possible in some way to show this content without editing embedded document? Should i use instead of array of bytes of word's icon an array of bytes of doc's screenshot?
Not sure i described it clear, so please ask
I'm afraid what you are asking for is almost impossible.
The only difference as far as the word file is concerned between the icon and the embedded file, is the image.
When you don't use a icon Word pretty much just take a screenshot of the document you are embedding and inserts that in place of the Icon graphic.
I've uploaded an example I grabbed from a Word file I made. Found this little gem in the /media folder inside the .docx file.
So basicly, your only choice in resolving this if you can't live with the Icon is to somehow grab a picture of the word-file you want to embed and insert that instead of the Icon image.
How you'd go about that can't be pretty. First of all the open xml sdk contains no such functionality. I tried playing a bit around with office interop as well, but no luck.
I only see two possible ways to achieve this.
First one is via Interop. You'll need to install a "pretend printer" like the ones that print to PDF instead of sending it to a printer. This one however needs to print to an image format. The format of the file in the Media folder was .emf but I'm not positive thats a requirement.
Anyways, should the above somehow be possible you could embed that picture, pretty much using the example you link from Microsoft, and just change this size of the "icon" which now would be an image of the document.
Second possibility would be to open the word document as a process, set the document size to 72% (or whatever makes the document be the only one on screen on your desktop) and the grab a print screen and cut it down to just the document and the use that as your image for the embedding.
For the record, I don't recommend you do any of the above, but thoose are the only options I see.
Should someone have a better solution to this I'm all ears.
Finally, should you decide that you want to push on with this, I'll be happy to code up an example of option number 2 if you reply and tell me you'd like that.

There is a nice wrapper API (Document Builder 2.2) around open xml specially designed to merge documents, with flexibility of choosing the paragraphs to merge etc. You can download it from here.
Using this tool you can embed a paragraph of another word document or entire word document as per your requirement.
The documentation and screen casts on how to use it are here.
Hope this helps.
