  • Obtain the pathName dynamically for ASP.NET MVC

    - by vikitor
    Hello, I'm looking for a solution that allows me to get the parent page pathname from a partialView invoked. For example I have an Action baa and a controller boo so the javascript to obtain this will be window.location.pathname, and it returns /boo/baa. The thing is that I use a partial view, so when I try to retrieve the pathname via the URL helper, what I obtain is the PartialView one, and what I need is the pathname for the action that invokes it. I want to do this because I want to show certain things of the partial view depending on the pathname of the parent view that invokes it. Is there a way to do this with ASP.NET MVC? Thank you all in advance,

  • How are value types implemented in .NET

    - by Michael
    Been looking around the net and can't find any articles about how value types are actually implemented. For instance, an Int32 is a struct and it's direct parent is System.ValueType and that's ultimate parent is System.Object. Object is a class - I imagine ValueType is a class? What's the class hierarchy? What part does the CLR have to play? At what stage and how does the CLR know to allocate value types to the stack? (FYI, I am aware that value types are stored where they are declared).

  • 'Best' way to pull data relative to a div?

    - by acidzombie24
    This answer suggested i should put my data in JS instead of a textarea. Thinking about it i could have scripts and do something like myarray[i]="data" where i is the index of my for loop. However when i click a div how do i find out what i is? I have used var data = $(this).parent('.parent').find('.valuestr').eq(0).val(); which is extremely simple. Should i use a script or should i continue to do it with a textarea? if i should use a script 1) Whats the easiest way to find i and 2) Is it bad pratice to have dozens or hundreds of <script> in my html? or i can go through the loop twice but i still dont know the easiest way to find i. I would have to store it somewhere or go through multiple tags and count them.

  • What is this Hash-like/Tree-like Construct Called?

    - by viatropos
    I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context. Here's how I use it: Config.get("root.parent.child_b") #=> "value" Here's what the class might look like: class Construct def get(path) # split path by "." # search tree for nodes end def set(key, value) # split path by "." # create tree node if necessary # set tree value end def tree { :root => { :parent => { :child_a => "value", :child_b => "another value" }, :another_parent => { :something => { :nesting => "goes on and on" } } } } end end Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.

  • What is the best way to "override" enums?

    - by Tyler
    I have a number of classes which extend an abstract class. The abstract parent class defines an enum with a set of values. Some of the subclasses inherit the parent class's enum values, but some of the subclasses need the enum values to be different. Is there any way to somehow override the enum for these particular subclasses, and if not, what is a good way to achieve what I'm describing? class ParentClass { private MyEnum m_EnumVal; public virtual MyEnum EnumVal { get { return m_EnumVal; } set { m_EnumVal = value; } } public enum MyEnum { a, b, c }; } class ChildClass : ParentClass { private MyEnum m_EnumVal; public virtual MyEnum EnumVal { get { return m_EnumVal; } set { m_EnumVal = value; } } public enum MyEnum { d, e, f }; }

  • Second CSS class not working in IE8.

    - by ProfK
    I have the following div being rendered to the client, but on IE, the checked-yes class is ignored. If I view the target element in the 'Developer Tools', that class is completely missing from the Style panel. The shift-item-present class is attached server side, and the checked-yes class client side, depending on the present attribute of the parent row, also shown below. <td><div class="shift-item-present checked-yes" jQuery1272958392665="94"/></td> Parent row: <tr class="shift-item" id="ctl00_mainContentPlaceHolder_ctl00_shiftList_ctl01_shiftRow" present="True" shift-id="641" jQuery1272958392665="64"> The page works perfectly in FF

  • how to exchange variables between extern iframe and site

    - by helle
    hey guys, for developement reasons (working with facebook-connect) i put the connect iframe in an iframe. on that way i am able to work on the connect-thing independent of my ip and don't have to develop on the live-server. the iframe holding the connect-button iframe is on my server, accessing the same db-server as the developer version (developer version is running on localhsot). as far as good ... BUT how can i let the parent site know, that the user has connected, so that i get his profile-picture displayd as reaction to this? how can i react in generally on an action/event/JS in an iframe? is there a way? can the iframe post data to the parent site? like a time-stamp and fb_userid? if the iframe stuff doesn't work ... i thougt of saving the ip to the fb_userid (to db) and check matches ... but i don't like this idea.

  • PyQt signal between QObjects

    - by geho
    I'm trying to make a view and controller in PyQt where the view is emitting a custom signal when a button is clicked, and the controller has one of its methods connected to the emitted signal. It does not work, however. The respond method is not called when I click the button. Any idea what I did wrong ? import sys from PyQt4.QtCore import * from PyQt4.QtGui import QPushButton, QVBoxLayout, QDialog, QApplication class TestView(QDialog): def __init__(self, parent=None): super(TestView, self).__init__(parent) self.button = QPushButton('Click') layout = QVBoxLayout() layout.addWidget(self.button) self.setLayout(layout) self.connect(self.button, SIGNAL('clicked()'), self.buttonClicked) def buttonClicked(self): self.emit(SIGNAL('request')) class TestController(QObject): def __init__(self, view): self.view = view self.connect(self.view, SIGNAL('request'), self.respond) def respond(self): print 'respond' app = QApplication(sys.argv) dialog = TestView() controller = TestController(dialog) dialog.show() app.exec_()

  • Restricting deletion with NHibernate

    - by FrontSvin
    I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

    - by oo
    i have this jquery code: $(this).parent('.copyFoodInstance').attr("myset", "0"); $(this).parent('.copyFoodInstance').html("<img BORDER=0 src='../../images/copy1.png' />"); it seems that when i call this code, this event fires: $(document).ready(function() { $('div.copyFoodInstance').live('click', function() { does anyone know why this event fires from the lines above? is there anyway to stop if from firing? All i am doing is updating an attribute on the div and updating the html. this shouldn't fire a click event?

  • Meshing different systems of keys together in XML Schema

    - by Tom W
    Hello SO, I'd like to ask people's thoughts on an XSD problem I've been pondering. The system I am trying to model is thus: I have a general type that represents some item in a hypothetical model. The type is abstract and will be inherited by all manner of different model objects, so the model is heterogeneous. Furthermore, some types exist only as children of other types. Objects are to be given an identifier, but the scope of uniqueness of this identifier varies. Some objects - we will call them P (for Parent) objects - must have a globally unique identifier. This is straightforward and can use the xs:key schema element. Other objects (we can call them C objects, for Child) are children of a P object and must have an identifier that is unique only in the scope of that parent. For example, object P1 has two children, object C1 and C2, and object P2 has one child, object C3. In this system, the identifiers given could be as follows: P1: 1 (1st P object globally) P2: 2 (2nd P object globally) C1: 1 (1st C object of P1) C2: 2 (2nd C object of P1) C3: 1 (1st C object of P2) I want the identity syntax of every model object to be identical if possible, therefore my first pass at implementing is to define a single type: <xs:complexType name="ModelElement"> <xs:attribute name="IDMode" type="IdentityMode"/> <xs:attribute name="Identifier" type="xs:string"/> </xs:complexType> where the IdentityMode is an enumerated value: <xs:simpleType name="IdentityMode"> <xs:restriction base="xs:string"> <xs:enumeration value="Identified"/> <xs:enumeration value="Indexed"/> <xs:enumeration value="None"/> </xs:restriction> </xs:simpleType> Here "Identified" signifies a global identifier, and "Indexed" indicates an identifier local only to the parent. My question is, how do I enforce these uniqueness conditions using unique, key or other schema elements based on the IdentityMode property of the given subtype of ModelElement?

  • Python/Tkinter make a custom window

    - by user1435947
    I want to make a window without the top taskbar (that is movable), so there is only thin outline around the GUI box. I also want to add my own 'X' to the box. import Tkinter class Application(Frame): def __init__(self, master=None): Frame.__init__(self, master) self.parent = master ............ def main(): root = Tk() root.attributes('-fullscreen', True) root.geometry('500x250+500+200') app = Application(root) app.parent.configure(background = 'gray32') root.resizable(width=FALSE, height=FALSE) app.mainloop() main() I tried forcing the box to resize after going into fullscreen to remove the taskbar, though box is no longer movable. Any suggestions? [I have seen this thread: Python/Tkinter: Removing/disabling a resizable window's maximize button under Windows The -toolwindow attribute didn't work for me, maybe because I use linux...]

  • WPF UserControl event called only once?

    - by 742
    Hi Everyone, I need to bind two-way a property of a user control to a property of a containing user control. I also need to set a default value to the property from code in the child (cannot be done easily from XAML tags). If I call my code from the child constructor, the value is set in the parent but the change callback routine is not triggered (my understanding is that the parent doesn't yet exist at the time the child is created). My current workaround is to catch the Loaded event of the child and to call the code from the handler. Howver as Loaded is called more than once, I need to set a flag to set the property only the first time. I don't like this way, but I don't know if there is a single shot event that could be used, or if this can be done otherwise. Any feedback based on your experience?

  • Constructors with inheritance in c++

    - by Crystal
    If you have 3 classes, with the parent class listed first shape- 2d shapes, 3d shapes - circle, sphere When you write your constructor for the circle class, would you ever just initialize the parent Shape object and then your current object, skipping the middle class. It seems to me you could have x,y coordinates for Shape and initialize those in the constructor, and initialize a radius in the circle or sphere class, but in 2d or 3d shape classes, I wouldn't know what to put in the constructor since it seems like it would be identical to shape. So is something like this valid Circle::Circle(int x, int y, int r) : Shape(x, y), r(r) {} I get a compile error of: illegal member initialization: 'Shape' is not a base or member So I wasn't sure if my code was legal or best practice even. Or if instead you'd have the middle class just do what the top level Shape class does TwoDimensionalShape::TwoDimensionalShape(int x, int y) : Shape (x, y) {} and then in the Circle class Circle::Circle(int x, int y, int r) : TwoDimensionalShape(x, y), r(r) {}

  • .focus() doesn't work on an input while orher attributes works

    - by Sirber
    I have a classic table / thead / tbody structure, which I add a line at the end of the tbody. The line contains only an input element. The code works in Firefox 3.6 but not in Chrome v5 or IE8. I'm using jQuery 1.4.1. Does not work: $("#" + AJAX_ID).parent().find('tr:last > td:nth-child(2) > input').focus(); Does work: $("#" + AJAX_ID).parent().find('tr:last > td:nth-child(2) > input').css('background-color', 'red'); even setting an ID on the input, and using document.getElementBuId('id').focus() doesn't work. Thank you!

  • Using Python, How to copy files in 'temporary internet files' folder in Windows

    - by pythBegin
    I am using this code to find files recursively in a folder , with size greater than 50000 bytes. def listall(parent): lis=[] for root, dirs, files in os.walk(parent): for name in files: if os.path.getsize(os.path.join(root,name))>500000: lis.append(os.path.join(root,name)) return lis This is working fine. But when I used this on 'temporary internet files' folder in windows, am getting this error. Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> listall(a) File "<pyshell#2>", line 5, in listall if os.path.getsize(os.path.join(root,name))>500000: File "C:\Python26\lib\genericpath.py", line 49, in getsize return os.stat(filename).st_size WindowsError: [Error 123] The filename, directory name, or volume label syntax is incorrect: 'C:\\Documents and Settings\\khedarnatha\\Local Settings\\Temporary Internet Files\\Content.IE5\\EDS8C2V7\\??????+1[1].jpg' I think this is because windows gives names with special characters in this specific folder... Please help to sort out this issue.

  • [Qt] How to make another window pop up that extends QWidget as opposed to QDialog?

    - by Graphics Noob
    So far I've only had my main window pop up other windows that were QDialogs and I'm not getting it to work with a QWidget. The other window I want to display was designed with the Form Editor, then wrapped in a class called ResultViewer which extends QWidget (as opposed to QDialog). What I want is to have the ResultViewer show its ui in a seperate window. Now when I try to display it the ResultViewer ui just pops up in the main window on top of the mainwindow ui. The code I'm using to display it is this (in my mainwindow.cpp file) ResultViewer * rv = new ResultView(this); rv->show(); The constructor for the ResultViewer looks like this ResultViewer::ResultViewer(QWidget * parent) : QWidget(parent), ui(new Ui::ResultViewer) { ui->setupUi(this); } I've looked through the QWidget documentation a bit but the only thing I can find that may be related is the QWidget::window() function, but the explanation isn't very clear, it just gives an example of changing the title of a window.

  • Forbid public Add and Delete for a List<T>

    - by aaginor
    Hi folks, in my C#-project, I have a class which contains a List public class MyClass { public MyClass parent; public List<MyClass> children; ... } I want to prevent the user of the class from Adding (and Deleting) an Element to the children-List, but he shall still be able to parse its elements. I want to handle the Adding and Deleting within MyClass, providing an AddChild(MyClass item) and DeleteChild(MyClass item) to ensure that, when an item is added to the child list, the parent of that item will be set properly. Any idea how to do this besides implementing my own IList? Thanks in advance, Frank

  • Building a linked list with LINQ

    - by FreshCode
    What is the fastest way to order an unordered list of elements by predecessor (or parent) element index using LINQ? Each element has a unique ID and the ID of that element's predecessor (or parent) element, from which a linked list can be built to represent an ordered state. Example ID | Predecessor's ID --------|-------------------- 20 | 81 81 | NULL 65 | 12 12 | 20 120 | 65 The sorted order is {81, 20, 12, 65, 120}. An (ordered) linked list can easily be assembled iteratively from these elements, but can it be done in fewer LINQ statements? Edit: I should have specified that IDs are not necessarily sequential. I chose 1 to 5 for simplicity. See updated element indices which are random.

  • FLEX: why the event is only listened by the dispatcher component ?

    - by Patrick
    hi, I've a parent (Canvas) with many children (LinkButtons) The linkButtons trigger an event to communicate between them: dispatchEvent(new SameBookmarkEvent("SameBookmarkEvent", bookmark.name)); and all linkButtons have a listener this.addEventListener("SameBookmarkEvent", highlightMe); ... private function highlightMe(e:SameBookmarkEvent):void { //do something } Now, the issue is that the event is only listened by the dispatcher child. In other words, only the child triggering the event, is receiving it. I was wondering what's wrong with it, and if I should add a listener to the parent (Canvas)... I basically need the children (LinkButton) communicate between them

  • Data Annotations validation Built into model

    - by Josh
    I want to build an object model that automatically wires in validation when I attempt to save an object. I am using DataAnnotations for my validation, and it all works well, but I think my inheritance is whacked. I am looking here for some guidance on a better way to wire in my validation. So, to build in validation I have this interface public interface IValidatable { bool IsValid { get; } ValidationResponse ValidationResults { get; } void Validate(); } Then, I have a base class that all my objects inherit from. I did a class because I wanted to wire in the validation calls automatically. The issue is that the validation has to know the type of the class is it validating. So I use Generics like so. public class CoreObjectBase<T> : IValidatable where T : CoreObjectBase<T> { #region IValidatable Members public virtual bool IsValid { get { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // return false if any violations occurred return !result.HasViolations; } } public virtual ValidationResponse ValidationResults { get { var result = new Validator<T>().Validate((T)this); return result; } } public virtual void Validate() { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // throw error if any violations were detected if (result.HasViolations) throw new RulesException(result.Errors); } #endregion } So, I have this circular inheritance statement. My classes look like this then: public class MyClass : CoreObjectBase<MyClass> { } But the problem occurs when I have a more complicated model. Because I can only inherit from one class, when I have a situation where inheritance makes sense I believe the child classes won't have validation on their properties. public class Parent : CoreObjectBase<Parent> { //properties validated } public class Child : Parent { //properties not validated? } I haven't really tested the validation in these cases yet, but I am pretty sure that anything in child with a data annotation on it will not be automatically validated when I call Child.Validate(); due to the way the inheritance is configured. Is there a better way to do this?
