  • Undefined variable from import when using wxPython in pydev

    - by Bibendum
    I just downloaded wxPython, and was running some of the sample programs from here. However, on every line that uses a variable from wx.*, I get a "Undefined variable from import error" For example, the following program generates five errors on lines 1,4,8, and two on line 5: import wx class MyFrame(wx.Frame): """ We simply derive a new class of Frame. """ def __init__(self, parent, title): wx.Frame.__init__(self, parent, title=title, size=(200,100)) self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE) self.Show(True) app = wx.App(False) frame = MyFrame(None, 'Small editor') app.MainLoop() The program, however, compiles and runs perfectly. I haven't made any significant modifications to pydev or eclipse, and the wxPython install is fresh.

  • Eclipse Outline View - Visible JavaScript Categories in Eclipse?

    - by leeand00
    I just found an option in the little white down arrow in Eclipse that reads "Visible Categories..." How can I use this? It seems to me that it could be used to only show functions that have an @category in their comments, but I haven't been able to make that work. If it did work it would be incredibly useful for separating out Unit Tests from their common-functions and separating them from the setUp and tearDown methods, so what is it really for? By the way I'm editing a Javascript file in the Eclipse "Javascript Editor", I don't know if that makes any difference or not.

  • Can I disable DataAnnotations validation on DefaultModelBinder?

    - by Max Toro
    I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great. If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.

  • WCF Proxy generation

    - by dragonfly
    Hi, I'm generating proxy using svcutil tool. My contract methods return objects of particular type. However generated proxy client interface has return value of type object. What is more I get exception with message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail] : The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:name. The InnerException message was 'XML 'Element' 'http://tempuri.org/:name' does not contain expected attribute 'http://schemas.microsoft.com/2003/10/Serialization/:Type'. The deserializer has no knowledge of which type to deserialize. Check that the type being serialized has the same contract as the type being deserialized.'. Please see InnerException for more details. Any ideas what's going on?

  • Error when trying to create a faceted plot in ggplot2

    - by John Horton
    I am trying to make a faceted plot in ggplot2 of the coefficients on the regressors from two linear models with the same predictors. The data frame I constructed is this: r.together> reg coef se y 1 (Intercept) 5.068608671 0.6990873 Labels 2 goodTRUE 0.310575129 0.5228815 Labels 3 indiaTRUE -1.196868662 0.5192330 Labels 4 moneyTRUE -0.586451273 0.6011257 Labels 5 maleTRUE -0.157618168 0.5332040 Labels 6 (Intercept) 4.225580743 0.6010509 Bonus 7 goodTRUE 1.272760149 0.4524954 Bonus 8 indiaTRUE -0.829588862 0.4492838 Bonus 9 moneyTRUE -0.003571476 0.5175601 Bonus 10 maleTRUE 0.977011737 0.4602726 Bonus The "y" column is a label for the model, reg are the regressors and coef and se are what you would think.

  • Java HTML parser/validator

    - by at
    We allow people to enter HTML code on our wiki-like site. But only a limited subset of HTML to not affect our styling and not allow malicious javascript code. Is there a good Java library on the server side to ensure that the code entered is valid? We tried creating an XML Schema document to validate against. The only issue there is the libraries we used to validate gave back cryptic error messages. What I want is for the validation library to actually fix the issue (if there was a style="" attribute added to an element, remove it). If fixing it is not easy, at least allow me to report a message to the user with the location of the error (an error code that I can present a nice message from is fine, probably even preferable).

  • Dynamic attributes with Rails and Mongoid

    - by japancheese
    Hello, I'm learning MongoDB through the Mongoid Ruby gem with Rails (Rails 3 beta 3), and I'm trying to come up with a way to create dynamic attributes on a model based on fields from another model, which I thought a schema-less database would be a good choice for. So for example, I'd have the models: class Account include Mongoid::Document field :name, :type => String field :token, :type => String field :info_needed, :type => Array embeds_many :members end class Member include Mongoid::Document embedded_in :account, :inverse_of => :members end I'm looking to take the "info_needed" attribute of the Account model and created dynamic attributes on the Member model based on what's inside. If club.info_needed was ["first_name", "last_name"], I'm trying to create a form that would save first_name and last_name attributes to the Member model. However, upon practice, I just keep getting "undefined method first_name=" errors on the Member model when trying to do this. I know MongoDB can handle dynamic attributes per record, but how can I get Mongoid to do this without an undefined method error?

  • Select all links from a Html table using XPath (and HtmlAgilityPack)

    - by Adam Asham
    What I am trying to achieve is to extract all links with a href attribute that starts with http://, https:// or /. These links lie within a table (tbody tr td etc) with a certain class. I thought I could specify just the the a element without the whole path to it but it does not seem to work. I get a NullReferenceException at the line that selects the links: var table = doc.DocumentNode.SelectSingleNode("//table[@class='containerTable']"); if (table != null) { foreach (HtmlNode item in table.SelectNodes("a[starts-with(@href, 'https://')]")) { //not working I don't know about any recommendations or best practices when it comes to XPath. Do I create overhead when I query the document two times?

  • eclipse debugger: attaching source-code of maven managed libraries

    - by meriton
    I'd like to use the source code of maven-managed dependencies when debugging our webapp in eclipse. I have managed to attach the sources to the libraries in the "Maven Managed Depedencies" classpath container, i.e. when I open a class file from a depedency (e.g. using Ctrl-Shift-T), I see the source code. However, when I launch the tomcat within eclipse, and execution halts on a breakpoint in that same class, the editor pane only displays the text "source not found", and a button to edit the "source lookup path". I have attempted to manually add the "Maven Managed Dependencies" classpath container, only to be told "Use maven project settings to configure depedency resolution". However, I see no useful setting in that property pane ... How can I attach those sources?

  • Just quick: How do you call a mutator from within a constructor in the same class?

    - by Blockhead
    For a homework assignment the instructions state (within Undergrad class): You do NOT need to include a default constructor, but you must write a full parameterized constructor (it takes 4 arguments) -- this constructor calls the parent class parameterized constructor and the mutator for year level. Because Undergrad extends Student, then Student is my parent class, right? I just can't quite figure out how I'm to use my year level mutator (which is just the simplest of methods) to assign my "year" attribute. public void setYear(int inYear) { year = inYear; } public Student(String inName, String inID, int inCredits) { name = inName; id = inID; credits = inCredits; } public Undergrad(String inName, String inID, int inCredits,int inYear) { super(inName, inID, inCredits); year = inYear; } I keep missing assignments because I spend too much time on these small specific points of the homework so just asking for a little help. I swear it's the wording that throws me off on these assignments almost as often as just learning the material itself.

  • Formatting an indented list in CSS

    - by Colen
    Hi, Let's say I have a list, with an arbitrary number of indentation levels, like so: Item Item Item Item Item Item Item Item Item Item Item If I'm displaying this list in an HTML document, how can I use CSS to handle the indentation? There might be an arbitrary number of indentation levels (although in practice there isn't going to be more than 5 or so). I don't want to create an "indent1" class that indents 10 pixels, an "indent2" class that indents 20 pixels, etc - that's clumsy. Is it possible to create a general rule that will indent by a certain distance based on an attribute value, or the position of an element in the hierarchy?

  • Load PDF from Memory ASP.Net

    - by Sandhurst
    I am using ITextSharp to generate pdf on the fly and then saving it to disk and display it using Frame. The Frame has an attribute called src where I pass the generated file name. This all is working fine what I want to achieve is passing the generated pdf file to Frame without saving it to disk. HtmlToPdfBuilder builder = new HtmlToPdfBuilder(PageSize.LETTER); HtmlPdfPage first = builder.AddPage(); //import an entire sheet builder.ImportStylesheet(Request.PhysicalApplicationPath + "CSS\\Stylesheet.css"); string coupon = CreateCoupon(); first.AppendHtml(coupon); byte[] file = builder.RenderPdf(); File.WriteAllBytes(Request.PhysicalApplicationPath+"final.pdf", file); printable.Attributes["src"] = "final.pdf";

  • MVC with cocoa/objective-c

    - by Leonardo
    Hi all, I have a strong j2ee background, and I am trying to move to objective-c for some desktop/iphone programming. I used many java web frameworks with mvc in mind, spring and struts ecc... so I am used to have servlet or controller which pass attributes to jsp pages, which is the view. In jsp pages with jstl you can call this attribute and render to video. In this way controller and view are (in theory) clearly separated. With xcode, I can easily recognize the controller and the view built with IBuilder. All the tutorial I found, shown the controller which go and change directly labels or text fields. So my two questions: seems to me that there's no separation between the two (controller and view), where I am wrong in that ? is there a way for a controller to pack all objects in a kind of context in a j2ee way and have the view read that context ? thanks Leonardo

  • JPQL / SQL: How to select * from a table with group by on a single column?

    - by DavidD
    I would like to select every column of a table, but want to have distinct values on a single attribute of my rows (City in the example). I don't want extra columns like counts or anything, just a limited number of results, and it seems like it is not possible to directly LIMIT results in a JPQL query. Original table: ID | Name | City --------------------------- 1 | John | NY 2 | Maria | LA 3 | John | LA 4 | Albert | NY Wanted result, if I do the distinct on the City: ID | Name | City --------------------------- 1 | John | NY 2 | Maria | LA What is the best way to do that? Thank you for your help.

  • In a Rails unit test, how can I get a User fixture to load its associated Profile?

    - by MikeJ
    In the documentation concerning Fixtures (http://api.rubyonrails.org/classes/Fixtures.html) they provide the following example of using label references for associations: ### in pirates.yml reginald: name: Reginald the Pirate monkey: george ### in monkeys.yml george: name: George the Monkey pirate: reginald So following their lead, I have a User model that has_one :profile, a Profile model that belongs_to :user, and tried to set up fixtures per their example: ### in users.yml reginald: id: 1 login: reginald ### in profiles.yml reginalds_profile: id: 1 name: Reginald the Pirate user: reginald (Note: since my association is one-way, the User fixture doesn't have a "profile: reginalds_profile" association--putting it in causes an error because the SQL table has no profile_id attribute.) The problem is, in my unit tests everything seems to load correctly, but users(:reginald).profile is always nil. What am I missing?

  • Create hyperlink to some text in NSTextView

    - by regulus6633
    I can create a hyperlink to some url in an NSTextView using the "Link Panel". Or I can add a link manually using the NSLinkAttributeName attribute of NSAttributedString. I don't want to make a hyperlink to some external url though, I want to be able to create a hyperlink to some text within the NSTextView. Do you know how in Pages you can set some text as a Bookmark, and then you can make a hyperlink to that bookmark? Any ideas or examples of how to go about that?

  • What is all this stuff in the CKEditor folder?

    - by Ashley Ward
    A while ago I downloaded the latest version (3.1) of the CKEditor text editor. The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so : <script type="text/javascript" src="ckeditor/ckeditor.js"></script> this works well. To make config changes, I have been modifying the ckeditor/config.js file. However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages. What is this _source folder? What is all the stuff at the root of the ckeditor folder? and, What is safe to remove from the folder?

  • jQuery prevent paste to iframe designmode from MS Word

    - by naugtur
    I've seen some questions on catching the paste event. This looks helpful. But I want to prevent paste on a designmode iframe from happening when the pasted content is not plaintext, but comes from MS Word or other WYSIWYG editor. What is experience on that? I suppose I should catch the event (bind to iframe or to its body?) and look for some specific tags in the clipboard. What content does Internet Explorer add every time? [edit] After doing more research I see there is no easy way to work with clipboard in non Internet Explorer browser except some Flash tricks. I don't want them. How can I detect paste in Firefox and others then?

  • Writing an Iron Python debugger

    - by Kragen
    As a learning exercise I'm writing myself a simple extension / plugin / macro framework using IronPython - I've gotten the basics working but I'd like to add some basic debugging support to make my script editor easier to work with. I've been hunting around on the internet a bit and I've found a couple of good resources on writing managed debuggers (including Mike Stall's excellent .Net Debugging blog and the MSDN documentaiton on the CLR Debugging API) - I understand that IronPython is essentially IL however apart from that I'm a tad lost on how to get started, in particular: Are there any significant differences between debugging a dynamic language (such as IronPython) to a static one (such as C#)? Do I need to execute my script in a special way to get IronPython to output suitable debugging information? Is debugging a script running inside the current process going to cause deadlocks, or does IronPython execute my script in a child process? Am I better off looking into how to produce a simple C# debugger first to get the general idea? (I'm not interested in the GUI aspect of making a debugger for now - I've already got a pretty good idea of how this might work)

The numbers are in the pastbin below. http://pastebin.com/HMLEAGhf Thanks!

  • Integrating CKeditor to my symfony2 project

    - by Jishnu G Nair
    I was trying to integrate ckeditor to my symfony2 project so that some of the textarea will have the ckeditor html editor. I brought the ckeditor on my required textarea by calling the class="ckeditor" in my form. The issue that I am facing now is that when I use the ckeditor the submit button of my form will not work instead I will have to use the built in "Save" option of the ckeditor toolbar for submitting the form. When I remove the ckeditor from the textareas and use normal textarea the submit button seems to work. I do not want to use the "Save" button on the ckeditor toolbar to submit my form. Is there a workaround to make the submit button work? Tried googling out for possible solutions but could not find any. P.S: I would also like to know if there are other html text editors like ckeditor that would work well with symfony2 and link to implementation instructions.
