I have a WinForms application and am using AxAcroPDF COM component to display PDF files in my application. I want to highlight occurrences of some text in the PDF document using the AxAcroPDF component. Is there a way to do that?
just since there are no answers here - according to Adobe's API there is a method SetCurrentHighlight, which hightlights text within the specified rectangle (I haven't tried this):
SetCurrentHighlight
Highlights the text selection within the specified bounding rectangle
on the current page.
Syntax void setCurrentHighlight(LONG nLeft, LONG nTop, LONG nRight,
LONG nBottom);
Another alternative way is there, you may like to do all kind of text editing features using Foxit PDF Reader. It is now available for major platforms like linux, Windows and Mac.
Mendeley (https://www.mendeley.com/) does the work like a charm!
In fact, Mendeley is more than a PDF-reader. You can use it to organize your docs and references .

I'm looking for a basic text editor or a plugin for an existing editor that can highlight the entire current column or vertical location of the cursor similar to the common option to highlight the entire currently selected row or line.
I think it would be very useful for indented code.
Does anyone know where I can find something like this?
I understand exactly what you're looking for and want it myself. I use Notepad++ (based on Scintilla) but there doesn't seem to be a "highlight current column" option the way they do provide for "highlight current line".
I looked at the plugin architecture and demo plugin package. I whipped up a proof of concept - very basic, surely buggy, that uses the long lines edge column indicator as the "highlight" for current cursor column. Not the best solution since if you're using the edge indicator, you "lose" it.
Source code on GitHub:
https://github.com/vinsworldcom/nppColHighlight
Notepad++
It's based on the Scintilla library which implements exactly that feature you're describing, basically highlighting a rectangular area.
To do so, hold Alt + Left Mouse or Alt + Shift + Arrow Keys to select.
If you still haven't found such an editor, PSPad editor has the feature.

Please see the attached screenshot (don't worry about the editor language in my screenshot, English (and several other languages) are also available).

this is how Chrome finds you a word when you search for it:
1) select it in all the places it appears.
2) draw little line in the scroll bar wherever it found the searched word.
I have a canvas with scroll view around it, and I want to perform the same thing on it.
I gues that for enabling the selection i'll have to use only richtextboxes ?!? (hope not).
any third party or idea or anything will be highly appreciated
Without looking directly at the Chormium Project (which is open source and available at Chormium Homepage) I would imaging what is happening on this particular example is something following these steps:
Word Highlighting
Search the page source/content for the keyword using a simple regex
Insert that text into some form of a HTML container (either a span or a div) with a particular id
Use CSS to style that container to indicated the highlighting
Sidebar Highlighting
Use some algorithmic method to vertical position of the highlighted term
Add a indicator to the side bar in a some presentation layer/control that is transparent and below the scroll bar
It may be possible that there exists a 3rd party control that does these things, or it may be possible to leverage your work off of the existing work in the chromium project. However it is most likely not done using a RichTextBoxes nor simple text selection.
I'd like to create a button containing an image (remove) from the VS2010 Image Library in WPF (...\_Common Elements\Actions\remove.png). This image actually contains four versions of the icon in different sizes. How do I go about using the first one of these?
Thanks,
Chris
I think that the files in the _Common Elements are meant to be used when creating or composing new icons, so you don't have to recreate the, well, common elements for each icon. Because of that, whenever I needed one of the icons from this, I just copied the one I needed into a new image and used that.
Read the readme files in the directory you want to use images from. For example it states in _Common Elements\Objects\_MSCommonElements_Objects - Readme.html (rough translation from my German version):
These common elements are supposed to be used during development and design of new custom icons.
When I read books about WPF, I saw the authors mention XPS like it was something important. Windows also includes its XPS viewer, and I've seen that listed as a "feature" of Windows.
But why? What's the point? Who the heck uses it? It's my understanding that XPS is, basically, like PDF, xhtml, or ePub (which is just xhtml)...or even Word's docx format. Many of the features are the same among those formats.
It doesn't seem to have any major benefits compared to any of those other formats. It seems to me that xhtml would be so much more useful than XPS as a way to save and load FlowDocuments from the RichTextBox. I've looked at multiple blogs about converting between the two. Most or all of the rich text on the internet is (x)html. Beyond that, I don't think anyone uses it just to publish their docs; PDF is preferred. It seems like XPS is just some random format that MS made and decided to push. I generally love MS, but they do have a habit of that kind of thing. Couldn't MS have made an api using xhtml instead? That would have been more useful in a lot of situations, I'd think.
So, is there a point to using XPS, particularly in comparison to one of the other formats I mentioned (or any I haven't)? Have you ever used XPS in your programs or otherwise?
As U62 already stated, WPF comes with a DocumentViewer control which enables you to view XPS documents. The DocumentViewer also has some useful fonctions like Print, Zoom, FitToPage etc... So you don't need to implement that or use a third party tool.
What I just finished an hour ago using XPS and the DocumentViewer was some kind of "Adress label print preview". Allow the user to select some contacts from a list of contacts, click "Print Preview". This opens a new XAML Window which contains a DocumentViewer control and a ListBox with the choice of different Labels (e.g. 1 sheet with 12 labels [2 columns, 6 rows], 1 sheet with a single label whose width and height can be user defined).
Based on the users selection, I generate an XPS Document in the layout the user selected with the adresses of the selected contacts. If e.g. the user selected 4 contacts and wishes to print them on "SingleLabelSheet"'s, I generate 1 XPS document with 4 pages, each page containing 1 Adress. Then I display the XPS in the DocumentViewer and the user can print the labels on our Label Printer.
Once I understood how the XPS API worked (at least the Basics), it was a matter of 2 hours to get this up and running.
So, basically, I see XPS as an easy to use API to display FixedDocuments which are to be generated on the fly. But I wouldn't personnally go about saving them to my HDD or somehow modify them or whatever you generally do with documents.
The only actual advantage I can think of is that you have a control for viewing XPS documents in WPF applications. The other formats you mention mean you would have to bring in a 3rd party renderer (or write one yourself if you have a year to spare).
btw. I don't know much about ePub, but XPS isn't directly comparable with XHTML, it's more like PDF in that it's designed to have a fixed layout.
XPS to WPF is like WMF to Win32/WinForms, it's a persistent format that let you store and print native WPF graphics.
XPS is used to print from WPF (even when you print directly from the application without saving, the internal printing system is built on XPS) so what should MS do:
Create a new file format that exactly fit with what they are trying to do
Build a 100% perfect translator from WPF to a format they don't control like PDF (and hope Adobe doesn't break all WPF applications out there with the next release of Acrobat Reader).
What would you do?
Saving XPS files is just a nice bonus.
Look, I may be a pessimist on XPS as a report generation solution, but I gave it a go and found the initial documentation to be hard to understand, with less real world samples out there than what I would have liked. When I put it into a real world business application I found it to be frustrating, particularly in LOB apps that require tables that span over multiple pages.
Things may have changed since then but as soon as I started looking at tables that spanned over several pages and I wanted column headers to go to the top, etc. I found that the API required me to do what I would call excessive workarounds with unnecessary complexity.
So, things may have changed since then (about 8 months ago), but I went from XPS to using ITextSharp and that has been a lot less painful.
So the only advantage I would say, like everyone else, is the built in viewer in WPF - but other than that I feel the API may need to "mature" a bit more before I will attempt something again in it.
Actually I found a really nice reason to use XPS. I wanted to print from multiple sources, merge documents and specify duplex and stapled. Finally it should be printed as one document with duplex and stapled. I was having a difficult time doing so but found that by printing to XPS (saved to disc) I could accomplish my goal with minimum fuss. I haven't found any other method that is so easy and straightforward.
Dim PrintServer As New SysPrint.PrintServer("\\" & My.Computer.Name)
Dim PrintQ As New SysPrint.PrintQueue(PrintServer, "Ricoh Main")
Dim Jobs As SysPrint.PrintJobInfoCollection = PrintQ.GetPrintJobInfoCollection
Dim able As SysPrint.PrintCapabilities = PrintQ.GetPrintCapabilities()
Dim CurrentTicket As SysPrint.PrintTicket = PrintQ.CurrentJobSettings.CurrentPrintTicket
If able.StaplingCapability IsNot Nothing AndAlso able.StaplingCapability.Count > 0 Then
If able.StaplingCapability.Contains(Printing.Stapling.StapleTopLeft) Then
CurrentTicket.Stapling = Printing.Stapling.StapleTopLeft
End If
Else
Debug.Print("no stapling capability")
End If
CurrentTicket.Duplexing = Printing.Duplexing.TwoSidedLongEdge
Dim fiName As String = "S:\Temp\PS\XPS\Test.xps"
Dim TestJob As SysPrint.PrintSystemJobInfo _
= PrintQ.AddJob("Test job", fiName, False)
XPS (code named "metro") was clearly designed as the Microsoft alternative to PDF and PostScript in Windows Vista. See this old article here: Microsoft Readies New Document Printing Specification
There are different approches when inventing document formats:
Some are made for quick view on screen (say low def) like HTML, doc.
Some other are (or can be) very respectuous of printing contrains (say quality based) like PDF, XPS.
So XPS whiches to be as good as PDF, plus it is formated in XML, so "maybe" it is more standard than the stream approch in PDF.
The black spot of XPS is maybe the management of special colors (Pantone, paper effects).
If i have a logo, let's say done as a jpg or even a png. Any suggestion for how I can use that to define a path geometry? It would be really good if any suggestions could be provided for how i can do it in blend.
Thanks
Yes - I just tackled this problem for an LOB application two days ago.
I can't offer advice for Blend (though I've read that it can be done in Expression Designer). However, the best free tool I've found for this is called InkScape (http://www.inkscape.org).
It's opensource, and while it's intended primarily for editing SVG vector-based images, it has two key features that are useful to us WPFers:
It can vectorize (i.e. "trace") raster images like bitmaps and jpegs, albeit not as well as one would hope, and
It can export the vector image as XAML
You'll invariably find that you get better results from loading vector formats (like SVG, EMF, WMF, etc) and saving to XAML, than if you try to convert a bitmap/jpeg... simply because the process of vectorizing a raster image is error prone at best. So if you want to bring a company logo into XAML, try to get hold of the source files used to create the logo (perhaps done in Illustrator?) and import that into InkScape.
If this post is helpful, please be kind and give it a one-up.
Jasema is a terrific tool right for the job.
Also, don't be shy to use Blend - it is somewhat more difficult to use (drawing shapes using pen) but it gets easier pretty fast. Switch on gridlines and optionally snap to them for good results.
What both Jasema and Blend are lacking, is the ability to easily create shapes with a central symmetry (like stars), so I took parts from Jasema and created my own tool (named Radius) that works a bit like a combination of a ruler and compass.
I have a good idea but you're png, bmp, jpg or other non vector file is must be very simple because we need best scan results and only use inkscape.
Step: Drag and drop your file workspace on Inkscape, download free.
Tip: If your image is color white, Top menu item File->Document Properties-> heck Checkerboard Background and if you want uncheck Page border show.
Step: Top menu item Path-> Trace Bitmap-> Mode check what you want property, i usually use color property and if your file is png check Remove Background then click OK, then wait again Ok button is Enable and close window.
Step: Now you have a two layer, top layer vektor file and bottom layer your file. Select vector file and top menu item Edit-> XML Editor-> select svg path and look side column, d name propery in your data path value.
But this method may not always work or may not give the desired results and draw your own shapes with the scape so you can get the path data from the XML editor.
Example, my first tests this like:
and after working on it some more:
I've solved my problem (export an image as XAML) using Microsoft Expression Design 4 (Free Version). I've downloaded from the link
http://www.microsoft.com/en-us/download/confirmation.aspx?id=36180
As input, I had Adobe Ilustrator files.
Adobe Illustrator / CorelDraw is perhaps the best tool out there for these operations that I have used.
Personally, I prefer illustrator for on-screen media. These tracings can be exported into several formats such as EPS, SVG, AI, or even XAML (with this plugin)
Best of Luck !!!!
I have recently been struggling with this myself. I had a set of icons done in data and needed to update them to look nicer.
I tried everything, manually typing them out. drawing in svg, converting svg to xaml.
in the end i found a list of open source icons from google material icons.
I then used this to convert from the svg files to data
https://github.com/BerndK/SvgToXaml
It works well but not for the icons i drew myself.
I decided to place all the icons data i convert into an app i built myself that will give you the data and a preview of the icon. feel free to use and contribute. I will keep updating as much as i can.

Convert your image from png to svg in online converter, then drop file into this site http://inloop.github.io/svg2android/ and you will see pathData of your image like below shown in my image.
