  • Implement master detail in one datagrid in wpf

    - by Archie
    Hello, I have classes as following: public class Property { public string PropertyName { get; set; } public int SumSubPropertValue; private List<SubProperty> propertyList; public void CalculateSumSubPropertValue { // implementation} } public class SubProperty { public string SubPropertyName { get; set; } public int SubPropertyValue { get; set; } } I have grouped the rows in datagrid on PropertyName . When the user clicks on PropertyName expnader the columns should display SubPropertyName and SubPropertyValue. Also SumSubPropertValue should appear in front of PropertyName in the expander header. My Datagrid is bound to a CollectionViewSource as follows: CollectionViewSource view = new CollectionViewSource(); view.Source = infoList; view.GroupDescriptions.Add(new PropertyGroupDescription("PropertyName")); Where infoList is ObservableCollection<Property>. My datagrid colmns look like <my:DataGrid.Columns> <my:DataGridTextColumn Header="SubPropertyName" Binding="{Binding SubPropertName}" Width="*"/> <my:DataGridTextColumn Header="SubPropertyValue" Binding="{Binding SubPropertyValue}" Width="*"/> </my:DataGrid.Columns> Can someone help me with it?

  • Getting the height of text to know fill height as in TCPDF

    - by sami
    I'm trying to go through the code of TCPDF to understand how it calculates the height of the text to be rendered, but it's too much for me to handle without asking. What I want to know: in the PDF from example 5 http://www.tcpdf.org/examples/example_005.pdf it gives the cell a yellow background. I'm guessing that at the basic level, it first draws a box with this fill color, then adds the text, so what method is it calling to get the height of the text to know the height of the box to fill? Anyone knows how to trace this, because doing it by hand and looking through the code isn't working at all for me.

  • Usercontrol access javascript from a Content's Page's Master Page

    - by Coda
    Hello all I have a problem. I have a masterpage that all of my Content pages inherit from. Within this masterpage I have a script tag pointing to the javascript file folder "~/Scripts/validation.js" On my content pages I use different usercontrols that require the use of many of the functions within the validation.js file however if I dont put the tag and the javascript functions within a contentholder on the contentpage the usercontrols do not see these functions and I get errors like "OnNameValidation" is not defined. Of course I can copy the javscript code into all of the pages but that's 30+ pages and a maintenance nightmare if I find a bug in one of the javscript functions. So the question (if you haven't already figured out from my long dissertation) is how can I declare the script tag with the path to the validation.js file so that contentpages and their usercontrols etc. can access the functions/code. Thanks in advance.

  • Implementing master-detail with 2 tables in a dataset (wpf)

    - by Dani
    I've created a dataset that contains 2 tables: Users (userID, UserName, other user details) Emails (Id, UserId, UserEmail) I populate the dataset using 2 DataAdapters (one for each table) I have a listbox, a few textboxes and a grid. listbox gets all the users, the few textboxs displays the user details when picked in the list box (this is easy b/c they are both bound to the same table). the grid should display the selected user's email addresses. How do I do it using binding ? is it possible or should I catch the selection change event and filter the grid "manually" (currently the grid displays all the emails in the tables).

  • Why do this PDF's fonts appear unreadable on my machine?

    - by Matthew
    I'm trying to read The Art of Assembly Language as per this answer on Stack Overflow. When I open it on my Ubuntu 12.04 box, it looks like this: I haven't tested it on another machine, but this can't be intentional. What is going on, and how can I fix it? Edit: The above screenshot is from Chrome. It look like this in Evince: Still squished and hardly readable, but better. Is there anything I can do to fix it?

  • WYSIWYG browser editor that generates *good* HTML?

    - by dauerbaustelle
    I'm searching for a "suck less" WYSIWYG browser HTML editor that generates good HTML code. (no <font>, <foo style="...">, <p></p><span></span><p><span>&nbsp;</span><span><span>blah</span></<span></p> and so on -- <b> and <i> etc is ok). Should be easy-to-use as it is going to be used by people that do not know what HTML is. Any suggestions? (I found a lot of editors but they all create that <font> and nested <span> crap that breaks site design and bloats a site with one table up to 100kB.)

  • How to render Asian characters in a PDF using xhtmlrenderer

    - by Mark Derricutt
    I was wondering what steps were needed to render Asian characters using the java based xhtmlrenderer (flying saucer) library? I am wanting to render the following: <html> <body>????????</body> </html> Without any font settings being added to the HTML this renders fine in normal browsers, but I can't find anyway to render this to PDF using the iTextRenderer portion of xhtmlrenderer. After following various threads on the mailing list, I see lots of posts talking about adding .TTF files from the c:\windows\fonts directory, and I have modified the examples to run on linux ( https://gist.github.com/643173745182c9becc57 ), which shows me various fonts being displayed, but I don't see any Asian glyffs. Does anyone have any decent pointers, or clean solutions to this problem? Or am I looking at the wrong problem with a really simple solution elsewhere?

  • Problem using Winforms WebBrowser control as editor

    - by thecaptain0220
    I am currently working on a project where I am using a WebBrowser control as an editor. I have design mode turned on and it seems to be working. The issue im having is when I try to save the Document and load another it pops up the "This document has been modified." message. What I am trying to do is as simple as this if (frontPage) { frontPage = false; frontContent = webEditor.DocumentText; webEditor.DocumentText = backContent; } else { frontPage = true; backContent = webEditor.DocumentText; webEditor.DocumentText = frontContent; } Like I said everytime I enter some text and run this code it just pops up a message saying its been modified and asks if I want to save. How can I get around this?

  • PDF Text Extraction Approach Using OCR

    - by Jon
    Has anybody attempted to extract text from a PDF using an OCR library and Java? What did you find to be the most reliable library for text extraction. Most of the approaches I've seen (tesseract, GOCR) are C libraries that would require some JNI code to be written. I'm familiar with pdfbox, which is now an Apache incubator project at version 0.8.x, but it's text extraction isn't always accurate. I'm looking for an alternative approach that is somewhat more reliable. I've not tried Asprise JavaPDF yet, in the process of trying that, but wanted to know more about the OCR approach (if it's possible). Any help would be appreciated.

  • WinForm PDF viewer with programatic search functionality

    - by Anthony Shaw
    We are currently using PDFTron's PDFView WinForm control to view PDF's in a WinForm application. I can load the file and search the file to highlight a certain text value. We have run into an issue where we have expired our trial license period and do not wish to shell out the $900/seat licensing on 15-20 computers. Does anybody know if the ActiveX Adobe Reader control can support the searching functionality programatically? I've tried that and the FoxIt Reader OCX control and neither seem to have this feature exposed (unless it's hidden really well) Does anybody have any suggestions for other freeware/open source viewers, or less-expensive viewers? TIA!

  • LocalReport (WebForms) and Partial Trust, for PDF Generation

    - by Peet Brits
    My goal is to generate a PDF for display in a web page, either as aspx or with a generic handler. (This will link from a Silverlight page, but this is irrelevant to the problem.) The problem is that LocalReport (Microsoft.Reporting.WebForms; Microsoft.ReportViewer.WebForms.dll) requires full trust, and our hosting server does not allow full trust. I am aware that ReportViewer has a remote mode that will allow it to run with partial trust, but for that I need a report server url which should probably have full trust as well, which does not solve anything. So how do I generate PDFs from WebForms in a partially trusted environment?

  • wmd editor sanitizing

    - by Ke
    hi, i am trying to find ways to sanitize the input of wmd editor Specifically, I am trying to make HTML tags only available in the <code>tags that wmd generates. Is that possible My problem is that the following code is rendered as html which is vunerable to potential xss attacks e.g. <a onmouseover="alert(1)" href="#">read this!</a> The above code renders normally both in preview mode and when saved to the db. I notice that SO doesnt seem to have this problem. The same code is just rendered as text. I notice that SO has shared their code here http://refactormycode.com/codes/333-sanitize-html Do I really have to use c# in order to sanitize wmd to do this? Any help appreciated , cheers Ke

  • Exception on dowloading Pdf file in ASP.NET

    I am downloading a Pdf file created by crystal report and I download as ReportDocument repDoc = ( ReportDocument ) System.Web.HttpContext.Current.Session["StudyReportCrystalDocument"]; // Stop buffering the response Response.Buffer = false; // Clear the response content and headers Response.ClearContent(); Response.ClearHeaders(); try { repDoc.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, Response, true, "StudyReport" ); } catch( Exception ex ) { } Eventhough it is working But I got an exception base {System.SystemException} = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.} Can anyone explain what is the reason for this and how to override the exception?

  • Programmer's editor or IDE for C code

    - by Yktula
    I feel like this question has been repeated here, but I couldn't find it. What open-source programmer's editor or IDE is best for writing code in C? A GUI and integration with Clang for static code analysis or git for version control would be convenient, but aren't necessary. I would ideally use two editors: one feature-filled IDE and one with a small memory footprint, but editors like jEdit, Geany, Diakonos, nano, etc. don't satisfy many of my needs, which include: Good support for refactoring and code completion. Extensibility in C or a "modern" scripting language (i.e. Ruby or Python) Relatively good performance and lack of bloated-ness

  • Visual studio editor issue

    - by viky
    I am using Visual Studio 2008. In my editor whenever I write an automatic property it's "get" and "set" wraps to a single line whenever I wrote "set" and put semicolon(;). like this: public string MyProperty { get; set; } I want it to be formatted like this public string MyProperty { get; set; } Currently I am manually formatting it to this after writing it. How can I set it as a default format?

  • core data editor problems

    - by Peyman
    I was recommended by someone in Stack Overflow to use Core Data Editor http://christian-kienle.de/CoreDataEditor/ to manage the sqlite persistent store. However the latest version (3.0) crashes on launch everytime. Older versions load but I see nothing when i point the config to the persistent store and the object model directories. There is no documentation either. can someone point me to the right place to sort this problem? I am trying to find a more manageable way to coordinate core data development than sqlite consoles. thank you

  • Text editor with "forensic" capabilities?

    - by Timo
    This is what happened: I wrote a perl script using TextWrangler and managed to change the encoding to UTF8 BOM, which inserts te BOM marker at the start of the file. Perl promptly misses the #! and mayhem ensues. It then takes me the better part of an afternoon to figure this out since most text editors do not show the BOM marker even with various "show invisibles" options turned on. Now, I've learned my lesson, I should have used less immediately, etc. etc.. What I'm wondering though is whether there is a text editor out there that lets you see every single byte of the file, even if they are "invisible"?

  • How to generate pdf files _with_ utf-8 multibyte characters using Zend Framework

    - by Sejanus
    Hello, I've got a "little" problem with Zend Framework Zend_Pdf class. Multibyte characters are stripped from generated pdf files. E.g. when I write aabccdee it becomes abcd with lithuanian letters stripped. I'm not sure if it's particularly Zend_Pdf problem or php in general. Source text is encoded in utf-8, as well as the php source file which does the job. Thank you in advance for your help ;) P.S. I run Zend Framework v. 1.6 and I use FONT_TIMES_BOLD font. FONT_TIMES_ROMAN does work

  • What Windows editor has CORRECT EOL whitespace handling?

    - by blueshift
    I'm looking for a Windows text editor for programming that handles EOL whitespace CORRECTLY, which for my idea of correct means: Strip all EOL whitespace on save, EXCEPT on lines that I haven't edited. This is to minimise the amount of EOL whitespace evil in my world, but not pollute SCM diff/blame with whitespace-only fixes (I have to deal with old / other people's code). I have played with TextPad, Notepad++, Kodomo Edit and Programmer's Notepad 2, and found all of them lacking. Also: I don't get along with vi, and I am unsure about Emacs on Windows. @Matti Virkkunen: I could mess with diff, but I want to fix the problem, not the symptoms. Fixing diff means all my, others, and server side diff tools need to be fixed, and doesn't fix space/noise/hash change issues in SCM. Example pet hate using that system: "update" tells me a file has changed. Diff shows no changes.

  • Is there a decent JSON editor around?

    - by al4nis
    I'm looking for a JSON editor that is able to do syntax checking and outline view. Browser-based editors are not an option as they are clumsy for editing lots of local files. Eclipse plug-in would be ideal, but I would be happy with anything that works. I found only two so far, those in Aptana Studio Pro and Spket IDE (both available as plug-ins for Eclipse). While they have decent outline views, their syntax checking doesn't catch most of the common errors (like missing commas or braces) which makes them almost useless.

  • Searching for a source code editor component

    - by Iso5786
    Hi, I have to develop a program at work in which a consultant can enter a specification which is developed 2 years ago here in house. So i can't really tell what it is about. But the editor should support some standard functionality such as syntax highlighting, auto completion and maybe search & replace. I've searched for Java components but didn't find a good solution which matches my requirements. Anybody knows a good component? It doesn't matter in which language it is written but I prefer Java.

  • Link to pdf within app

    - by Thijs
    I've got an iOS app that at one point opens a link to a website in a webview. These links are kept in a plist file (so it is easy to maintain them as the app evolves). What I want to do next is to also link to PDF's (or any picture of text file format, of even a html format, this is flexible) that are kept within the app. And I would like to do this as much as possible from within the existing app structure. So, is it possible to create a link that can be put in the plist as a web-link, but instead opens a file on the device itself (possibly in the webview)? And how would I go about that? Any ideas? Thanx in advance for your help!
