  • XmlNode.InnerText

    - by Jonathan.Peppers
    We have XML like so: <Example> <Node>Some text here <ChildNode>Child 1</ChildNode> <ChildNode>Child 2</ChildNode> </Node> </Example> We are using XmlDocument to parse this. When we have the XmlNode of the Node element, XmlNode.InnerText returns us this: "Some text hereChild 1Child2" How can we get the inner text of the Node element without the child nodes' inner text? We don't really want to use any Regex or string splitting to accomplish this. Note: We also don't want to switch to using a different set of classes to parse this XML, it would be too much of a code change.

  • Django - raw_id_fields title not refreshing.

    - by James Howell
    Hi, I am currently having an issue when using the raw_id_field within admin.py in my Django project. My site's admin area has a number of image upload fields for various different model pages which are all ForeignKey fields to an Image model where all images for the site are stored. As the site will eventually be dealing with a large quantity of images (100s, maybe 1000s) the default select box would be unusable. I created various admin.ModelAdmin classes e.g class InfoSlideAdmin(admin.ModelAdmin): raw_id_fields=('image',) These change the image selector within my Edit pages from a Select Box to a Raw ID Field. However when I select a different image using this control although the ID of the new image is shown the title from the previous image still displays. Any ideas?

  • website is very slow on IE

    - by Bhupi
    Hi, I need to know what can be the main reasons (apart from the basics like grouping CSS selectors, reducing image size, using image sprite etc.) which makes a website slow on Internet Explorer, because my website works fine on the others like FF, chrome etc. Is it the huge use of Javascript framework (ie. jQuery, extjs, prototype)? Is it because of the use of plugins based on JS framework? Should I use core javascript and remove the use of any js framework? Should I try to avoid using jQuery(document).ready()? in case of jQuery framework? Above some of the questions which I know and please answer the questions which I couldn't ask because of lesser knowledge about these. I need to make my website perform well on IE (6,7,8) also please suggest. Thanks

  • Wrapping pre-made elements using GWT?

    - by user246114
    Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

  • how to display "complex" widgets in a list in pyqt?

    - by Giorgio Gelardi
    I'm quite new to QT and I have to display a list of "panels" like this: My datamodel handles different classes' instances, so having more than one panel layout would be great - but it's not a requirement. Btw I have to catch mouse clicks on the images to execute related actions. I'm thinking about use some html capable widget (QWebPage?) to render the items in a QListView or QListWidget, but as I said, I don't know QTs so much and need a direction (delegates? stylesheets?). Any help will be appreciated.

  • Long task in Javascript

    - by Misha Moroshko
    Why in the following code I see the whole page at once ? Thanks ! HTML: <div></div> CSS: div { width: 100px; height: 300px; border: 1px solid black; text-align: center; } Javascript: $(function() { for (var i=0; i<15; i++) { sleep(100); $("div").append("<span>--- " + i + " ---<br /></span>"); } function sleep(milliseconds) { var start = new Date().getTime(); for (var i = 0; i < 1e7; i++) { if ((new Date().getTime() - start) > milliseconds){ break; } } } });

  • C# Elegant way to handle checking for an item in a collection.

    - by JL
    I've posted a code sample below. Firstly let me explain termStore.Groups in the code below is a collection of Group Objects (The exact class is irrelevant). Checking for null : if (termStore.Groups[groupName] == null) seems like a logical (clean) approach, but if the Groups collection is empty then an exception is produced. using the termStore.Groups.Contains is not an option either because this expects a strong type i.e: .Contains(Group)... not .Contains(GroupName as string) Can someone recommend a clean / generic way I can check for if an item exists in collection . Thank you.... TermStore termStore = session.TermStores.Where(ts => ts.Name == termStoreName).FirstOrDefault(); if (termStore.Groups[groupName] == null) { termStore.CreateGroup(groupName); termStore.CommitAll(); } Update: The exact class Sharepoint Taxonomy Classes. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.taxonomy.group.aspx

  • Content Types in browsers, can we use the Mime??

    - by SoLoGHoST
    Ok, I am wondering which mime types are dangerous in browsers? That is to say setting the Content Type to that mime type?? Which mime types, if any would pose a security risk?? I am noticing that many forum software, when uploading files, use the application/octet-stream for any files other than images and place that into the Content Type of the header. I am wondering why don't they place the actual mime-type instead into the Content Type? Are there security risks involved with this? So far I have used text/css, text/plain, audio/mpeg, and many others and haven't noticed any difference between application/octet-stream and these others. Does anyone out there know the exact difference, and what makes application/octet-stream any better, or any worse...to use for the Content Type?? Thank You :)

  • How can I split the suckerfish Menu into two pieces so that I can put it in two frame?

    - by Kai
    I found a tutorial for developing multi-level drop down menu here.Its demo can be checked at www.kriesi.at/wp-content/extra_data/suckerfish_tutorial/step4.html#. I would like to enhance it to support cross-frames . It means, the horizontal part of the whole menu (html,css,javascript etc..in demo page) will exist in the upper frame and the rest will be put in the lower frame. Edit: There will be only one menu item in the horizontal part. It will be still ok if I can click that menu_item rather than mouse-hovering to show the lower part of the menu . Any idea will be appreciated. Thanks.

  • How do I set up Array/List dependencies in code with Castle Windsor?

    - by SharePoint Newbie
    Hi, I have the following classes: class Repository : IRepository class ReadOnlyRepository : Repository abstract class Command abstract CommandImpl : Command { public CommandImpl(Repository repository){} } class Service { public Service (Command[] commands){} } I register them in code as follows: var container = new Container("WindsorCOntainer.config"); var container = new WindsorContainer(new XmlInterpreter("WindsorConfig.xml")); container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel)); container.AddComponent("repository", typeof(RentServiceRepository)); container.Resolve<RentServiceRepository>(); container.AddComponent("command", typeof(COmmandImpl)); container.AddComponent("rentService", typeof (RentService)); container.Resolve<RentService>(); // Fails here I get the message that "RentService is waiting for dependency commands" What am I doing wrong?

  • C# Event routing in code behind

    - by Nate
    I'm building a WPF MVVM-ish application. I want to be able to display an event log containing items in a collection that exists in my viewmodel. I want any of the objects in the model to be able to add data to the event log. Therefore every object needs to be able to pass data back to one central collection for databinding in the view. I could implement an event in every one of my data classes and manually pass the events up the object heirarchy but this seems super clumsy. On the visual tree a Routed Event would take care of this, is there some equivelent in the model scope? Any other ideas?

  • How to write a tool, inverting colors in Windows?

    - by vlood
    I read a topic in this site about it, but decided to post another one as I want to write such a tool, but I don't have much experience in C# & .NET, so it could take me too much time just digging the Net, while someone can just direct me to the right library or classes to be used. So, straight to the point. I want to write a tool that, when activated, inverts absolutely all items on the screen and lets you work that way without torturing your eyes with bright light colors. Does anyone have an idea of the needed .NET libraries or third-party frameworks, to implement this? Any help will be greatly appreciated! P.S. Changing to "High Contrast" theme in Windows is not the solution I seek, so please, don't mention it!

  • how to implement this observer pattern?

    - by lethal
    Hello. I have 4 classes, that describe state diagram. Node, Edge, ComponentOfNode, ComponentOfEdge. ComponentOfEdge compounds from ComponentsOfNode. Node can have 0..n outgoing edges. Edge can have only 2 nodes. Edge should be able to offer ComponentOfNode, but only from nodes that Edge has, in form ComponentOfEdge. The user can change ComponentsOfNode. I need this change spreads to all Edge. Hw to do it? I expect the observer should be used. Can you give me example in pseudocode please?

  • Xcode File management. What is best practice?

    - by ian1971
    I've been using Xcode for a while now. One thing that always bugs me is the way it handles files. I like to have my files all in nested folders rather than one big physical folder, but when you create a group in Xcode by default it does not create a folder just a virtual folder within the project. I can see that virtual folders are great for linking code in arbitrary places into your project but once you get beyond a few classes I find the one big folder approach really painful. And then if you try to fix it later it takes ages and is easy to break your build. Is it possible to change this behaviour so that by default it creates a physical folder? Or am I doing it wrong and trying to cling to some other way of working? How do other people work with files in Xcode?

  • Active Record's SessionScope in BL or DL ?

    - by StupidDeveloper
    Imagine that I have 3 projects: DL, BL and WS. DL contains Active Record implementation with all the mappings, BL has some logic (calling various DL methods) and finally WebService project exposes some BL methods (using some DTO mappings). The questions are: Should I put all data related methods in DL or is it allowed to use SessionScope in BL ? There are some complicated stuff that is right now done on BL. Should/can BL operate on classes-mappings of the Active record? The question is where should be the translation to DTO be made (at the BL level? ) ?

  • How to change the pop-up position of the jQuery DatePicker control

    - by gfrizzle
    Any idea how to get the DatePicker to appear at the end of the associated text box instead of directly below it? What tends to happen is that the text box is towards the bottom of the page and the DatePicker shifts up to account for it and totally covers the text box. If the user wants to type the date instead of pick it, they can't. I'd rather have it appear just after the text box so it doesn't matter how it adjusts vertically. Any idea how to control the positioning? I didn't see any settings for the widget, and I haven't had any luck tweaking the CSS settings, but I could easily be missing something.

  • c# .net framework subtracting time-span from date

    - by smkngspcmn
    I want to subtract a time-span from a date-time object. Date is 1983/5/1 13:0:0 (y/m/d-h:m:s) Time span is 2/4/28-2:51:0 (y/m/d-h:m:s) I can use the native DateTime and TimeSpan objects to do this, after converting years and months of the time-span to days (assuming a 30 day month and a ~364 day year). new DateTime(1981,5,1,13,0,0).Subtract(new TimeSpan(878,13,51,0)); With this i get the result: {12/4/1978 11:09:00 PM} But this is not exactly what i expected. If i do this manually (assuming a 30 day month) i get 1981/0/3-10:9:0 This is pretty close to what i'm after except i shouldn't get 0 for month and year should be 1980. So can someone please show me how i can do this manually and avoid getting a 0 month value? Also why do i get a completely different value when i use native classes?

  • is counter has certain value inside a class in python

    - by mazlor
    i am learning classes in python and when i was reading the documentation i found this example that i didn't understand : class MyClass: """A simple example class""" def __init__(self): self.data = [] i = 12345 def f(self): return 'hello world' then if we assign : x = MyClass() x.counter = 1 now if we implement while loop : while x.counter < 10: x.counter = x.counter * 2 so the value of x.counter will be : 16 while for example if we have a variable y : y = 1 while y < 1 : y = y *2 then if we look for the value of y we find it 1 so i don't know how is the value of counter became 16 . thanks

  • adding a background color to search term results

    - by turborogue
    I'm trying to add a background color to a user submitted search result when a user enters a search term on a page (which is basically one big table). This is a text based search. I'm using jquery to show/hide the table rows that do not have the search term as text within the TR, but I'd ideally like to take the additional step of taking the search term (the entered value), and matching any of those text terms in the remaining (showing) rows and adding say a yellow background to the word(s). I know my syntax is currently wrong, just not sure what is correct:) Hopefully this is clear...any help is greatly appreciated! html of form: jquery: $("#searchsubmit").click(function () { var searchexp = document.getElementById('searchbox').value; $("table tr").hide(); $("table tr.header").show(); $('tr:contains('+ searchexp +')').show(); $(searchexp).css('background-color','yellow'); });

  • AngularJS, changing the data in a view without div disappearing

    - by Jascination
    I'm making a little wizard/survey in AngularJS which loads in data to a variable, $scope.styles. I've set up a plunkr for ease of use here: http://plnkr.co/edit/1S542YE7xlO2P4zyhzu0?p=preview Pretty simple. I show each object to the user in succession, which loads in the pertinent images and displays them for the user. clicking "yes/no" at the bottom of the images it loads in the next gallery. There is a big of lag between the refresh here (Plunkr seems to be loading it quite quickly, but this is not the case on my production server so it's even more noticable) which causes the window size to momentarily be much smaller plus all the content below the ng-repeat jumps to the top of the screen. What's the best way to prevent this from happening? Is CSS the only solution here?

  • Type hinting and optional attributes in PHP

    - by Álvaro G. Vicario
    I have a class method that deals with dates: public function setAvailability(DateTime $start, DateTime $end){ } Since item availability can have lower limit, upper limit, both or none, I'd like to make setAvailability() accept NULL values as well. However, the NULL constant violates the type hinting: $foo->setAvailability(NULL, $end); triggers: Catchable fatal error: Argument 1 passed to Foo::setAvailability() must be an instance of DateTime, null given And, as far as I know, I cannot have a DateTime instance with no value. (Can I?) For a reason I cannot grasp, this seems to work: public function setAvailability(DateTime $start=NULL, DateTime $end=NULL){ } ... $foo->setAvailability(NULL, $end); But it looks like a hack that works by pure chance. How would you deal with unset dates in PHP classes?

  • is right to implement a business logic in the type binding DI framwork?

    - by Martino
    public IRedirect FactoryStrategyRedirect() { if (_PasswordExpired) { return _UpdatePasswordRedirectorFactory.Create(); } else { return _DefaultRedirectorFactory.Create(); } } This strategy factory method can be replaced with type binding and when clause: Bind<IRedirect>.To<UpdatePasswordRedirector>.When(c=> c.kernel.get<SomeContext>().PasswordExpired()) Bind<IRedirect>.To<DefaultRedirector>.When(c=> not c.kernel.get<SomeContext>().PasswordExpired()) I wonder which of the two approaches is the more correct. What are the pros and cons. Especially in the case in which the logic is more complex with more variables to test and more concrete classes to return. is right to implement a business logic in the binding?
