  • printing using one '\n'

    - by Alex
    I am pretty sure all of you are familiar with the concept of the Big4, and I have several stuffs to do print in each of the constructor, assignment, destructor, and copy constructor. The restriction is this: I CAN'T use more than one newline (e.g., ƒn or std::endl) in any method I can have a method called print, so I am guessing print is where I will put that precious one and only '\n', my problem is that how can the method print which prints different things on each of the element I want to print in each of the Big4? Any idea? Maybe overloading the Big4?

  • Binding expression failing.

    - by Rohit Kandhal
    My output window is flooded with binding expression failures like : "Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=DataContext.CurrentActivationObjectType; DataItem=null; target element is 'StackPanel' (Name=''); target property is 'NoTarget' (type 'Object')" and similar binding issues. Also i found that these failure occurs only when the screen loads (i.e. first time) No failures there after. I've checked the binding it is fine . Binding :

  • How do I layout a form in WPF using grid or other controls for maintainability

    - by Jason Coyne
    I have a WPF form, I want to lay out a standard form onto it. Each form element will have a label, and then a control. Pretty standard stuff. If I use a wrap panel, it can cause the label and the control to be separated, but I want them to stay together. is there some WPF equivalent of nobr? Grid works, and allows for column spanning etc, however I really really hate that you specify the column and row on each control. This makes it extremely inconvenient to reorder or insert things into the list. Is there a way to get the grid to use more HTML style column/rows where the items are a child of the row they are in, so that I can re-order easily? Is there some other control that will let me layout a form easily?

  • Change background colour of individual elements on the fly

    - by John
    Hi, Is there a way in CSS or JQuery where I can dynamically change the background of li tags so they get slightly lighter for each element until it gets to white. For example say I had a list of 10 li elements. The first would have a red (#ff0000) background, the next one would then be a lighter shade of red, and so on and so on until we got to the last one which would have a background of white (#FFFFFF) The list can be any length and i just want the background colour to go from one colour e.g. red to another colour e.g. white. My site uses JQuery so if I have to use that I don't mind. Thanks

  • Flash AS 3 Loader OnComplete Inside a Loop

    - by meengla
    Hi, I think I posted my question as an answer elsewhere (http://stackoverflow.com/questions/2338317/how-to-get-associated-urlrequest-from-event-complete-fired-by-urlloader/2776515#2776515) . Sorry. Here is my question again: Hi, How can I make your function work for loader object in a loop? Thanks! Meengla Here is my existing (rough) code; I always get the mylabel from the last element of the array. var _loader = new Loader(); for (j = 0; j < 5; j++) { //mylabel variable is correct setup in the loop _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, function(e:Event):void { doneLoad(e, mylabel); }); _loader.load(new URLRequest(encodeURI(recAC[j].url))); }//for loop

  • Is there a way to determine if a <select> dropdown menu is open?

    - by Robert
    I'm looking for a way to determine if/when a <select> element's menu is open. I don't need to force it to open or close, just figure out if it's open or closed at a given time. I can listen to events for focus/blur, mouseup/mousedown, etc., but I don't think I can reliably figure out the state of the menu from those events. For example, mousedown followed by mouseup could mean the user clicked and dragged to a selection and released (in which case the menu is now closed) or clicked and released to open the menu (in which case the menu is open). It also seems likely that the specific behavior of dropdown menus is browser-dependent. I know I could do this if I roll my own dropdown menu, but I prefer to use <select>. Is there a reliable way to find out if a dropdown menu is open? Or is this something that Javascript can't know?

  • How to load images and fragments dynamically in LiveCycle Designer forms?

    - by John
    Hi there. I've created a couple of shared templates (.xdp) which will be shared among several clients. Obviously, each client has their own logo and I'd like to set the logo upon form generation. I've managed to change the logo dynamically although I'm not sure if my approach is good. In the xml datasource I've got this element: <ClientID>SomeNumber</ClientId> In the form itself I set the image href with this javascript code: SomeHiddenTextField::calculate HeaderLogo.value.image.href = $record.ClientID + "_logo.jpg"; I've got the logos stored on the server in the same folder as the shared templates. Is this an alright approach to load logos dynamically? I've been trying to achieve the same dynamic behaviour with each client's footer fragment, but I have been unable to figure out how to load these on demand. I could make each footer fragment in to an image but I'd like to avoid it if possible.

  • DOM: how to import nodes and give them different namespace prefix

    - by thomasrutter
    I'm familiar with the DOMDocument::importNode method for importing a tree of nodes from some other document element. However, what I was wondering is if I can automatically change the namespace prefix on a tree of nodes as I import them, that is, specify a new prefix for all nodes of that namespace. Say the nodes, in their existing document, all have names like "name", "identity", and so on. When importing them into my new document they will be alongside other namespaces, so I'd like them to appear as "nicnames:name", "nicnames:identity" and so on. I'd like to be able to change this prefix programmatically so that in another context I may be able to import them as, for instance, "myprefix:name", "myprefix:identity" depending on the document they're imported into. Can anyone help me understand how to do this? Thanks

  • Generics in custom configuration sections

    - by Jonn
    I tried making a custom configuration class that went on like this: WatcherServiceInfoSection<TWatcherServiceDetailElement> where TWatcherServiceDetailElement is a ConfigurationElement inside it. Now when I call the type in the ConfigSections area of AppConfig I get the error: An error occurred creating the configuration section handler for WatcherServiceInfo: Could not load type 'Library.Common.Utilities.ConfigurationHandler.WatcherServiceInfoSection<ASNDPService.Configuration.WatcherServiceDetailElement>' from assembly Is what I'm doing possible? Can I have generic types in the type attribute for a custom section element? EDIT Additionally, how about ConfigurationElementCollection objects? Like in the above example, how could I do a [ConfigurationProperty("WatcherServiceDetails", IsRequired = true, IsDefaultCollection = true)] [ConfigurationCollection(typeof(TWatcherServiceDetailElement), AddItemName = "WatcherServiceDetail")] public WatcherServiceDetailCollection<TWatcherServiceDetailElement> WatcherServiceDetails I'm aware that type parameters aren't allowed for attributes and that's what I want to know how to do.

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

  • Cannot change style of HTML elements using jQuery by content script

    - by Moctava Farzán
    I'm writing an extension for chrome as "Content script". My extension should change the background color of google home page (https://www.google.com) I wrote this code (including jquery): $(".gsib_a").style="background:#FF0000"; But not worked. I'm sure I added jQuery to content script, and the manifest.json file is set. I am sure because this code works: $(".gsib_a").hide(); And I am sure changing style of the element with class of gsib_a is exactly what I need and affects. Because I've tested it by Chrome Developer Tools. Okay, who knows the problem?

  • Create xml type with no body

    - by Pace
    Hopefully this is an easy question. How can I define an XML type such that the type doesn't have a body. As an example I can define the Foo type as follows... <xs:complexType name="Foo"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="id" type="xs:integer" use="required"/> </xs:extension> </xs:simpleContent> </xs:complexType> But that would allow the following... <Foo id="7">STUFF I DON'T WANT</Foo> Is there a way I can change the xsd so that the Foo element isn't allowed any body?

  • Creating a C# webservice client having SoapParameterStyle as Bare as opposed to wrapped

    - by Pratik Bhatt
    I am trying to create a Soap Web Service Client using the Visual C# 2008 Express IDE. I Do that by Right-Clicking Project Name-Add service Reference. Everything is working out fine, and the client is being generated as follows [System.Web.Services.Protocols.SoapDocumentMethodAttribute("operationInfo", RequestElementName="mainInfoTag", RequestNamespace="http://www.example.com/test", ResponseElementName="Answer", ResponseNamespace="http://www.example.com/test", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("somenewID")] public string storeWarrantyInformation(tagBelowMainInfoTag tag, out string somenewID, out string someotherID) As you can see, the method is marked with SoapParameterStyle.Wrapped, what this is does is that it does not create a class corresponding "mainInfoTag". The Questions I have is what determines the Client SoapParameterStyle in the proxy class. I would like to get SoapParamterStyle as Bare, so that I have access to the root XML element. Is there some setting I can specify in the IDE or through 'wsdl.exe' to make this happen.

  • Problem in passing arrays from C# to C++

    - by Rakesh K
    Hi, I have an application in which I need to pass an array from C# to a C++ DLL. What is the best method to do it? I did some search on Internet and figured out that I need to pass the arrays from C# using ref. The code for the same: status = IterateCL(ref input, ref output); The input and output arrays are of length 20. and the corresponding code in C++ DLL is IterateCL(int *&inArray, int *&outArray) This works fine for once. But if I try to call the function from C# in a loop the second time, the input array in C# is showing up as an array of one element. Why is this happening and please help me how I can call this function iteratively from C#. Thanks, Rakesh.

  • What is the preferred way to associate css styles with GWT widgets (using UiBinder)?

    - by smallbec
    From the GWT page (http://code.google.com/webtoolkit/doc/latest/DevGuideUiCss.html#cssfiles), it mentions 2 ways (for modern application): Using a CssResource contained within a ClientBundle. Using an inline element in a UiBinder template. Modern GWT applications typically use a combination of CssResource and UiBinder. So my question is, when should I use a css file and create a CssResource for it, and when should I define styles directly in the ui.xml file using <ui:style>? Are there any performance implication (i.e. resource size to download on the client) with either of these ways?

  • How can I bind dynamic data to DataGridTemplateColumn in code?

    - by TuomoT
    I'm using DataGrid from CodePlex. I have objects (ICustomTypeDescriptor) that have properties 'name' 'description' 'c' 'd' and so on (the names are dynamic, and so is the value) and they have information behind them. I have templates for different types. And if I have to list the properties of a single element I can just bind to the values in xaml and use datatemplateselector (in datagridtemplatecolumn) which will pick the correct template. However, when I'm listing several of the elements, how can I use the selectors and the templates? How do I get the correct property bound to the template (two-way)? When ignoring the need for different templates, using DataGridTextColumn with bindings is very simple (and works, see example below), is there any way to use similar approach with the DataGridTemplateColumn? foreach (String propertyName in listOfPropertyNames) { DataGridTextColumn textColumn = new DataGridTextColumn() { Header = propertyName, Binding = new Binding() { Path = new PropertyPath(propertyName) } }; DataGrid.Columns.Add(textColumn); }

  • CSS: Why won't this box get wider?

    - by Jason
    I just need a sanity check here... DEMO Basically, I can't figure out how to get the box under the link to get wider as more content is added. It seems fixed to the width of the parent div (or the width of, say, the longest element like the select or a really long word with no spaces), despite being absolutely positioned. I use this trick all the time with ul and li but it doesn't make sense to use that in my situation, and for some crazy reason it just won't work with a div inside a div. I don't want to set a width (which, of course, works) because I don't always know what will be in this box. GRR Thanks :\

  • Can I create a collection in Scala that uses different equals/hashCode/compare implementations?

    - by Willis Blackburn
    I'm looking for as simple way to create an identity set. I just want to be able to keep track of whether or not I've "seen" a particular object while traversing a graph. I can't use a regular Set because Set uses "==" (the equals method in Scala) to compare elements. What I want is a Set that uses "eq." Is there any way to create a Set in Scala that uses some application-specified method for testing equality rather than calling equals on the set elements? I looked for some kind of "wrapEquals" method that I could override but did not find it. I know that I could use Java's IdentityHashMap, but I'm looking for something more general-purpose. Another idea I had was to just wrap each set element in another object that implements equals in terms of eq, but it's wasteful to generate tons of new objects just to get a new equals implementation. Thanks!

  • Finding final/effective web.config values (from inherited configurations)

    - by gregmac
    Are there any apps that can show the final configuration as applied to a particular application directory? What I'm picturing is something along the lines of FireBug's CSS viewer. Basically, it should show the equivalent single web.config file (as if you only had one), with all the values that apply to the directory in question, with each element (or even attribute) annotated with its source (the real .config file it came from). This would greatly help deploying applications into foreign environments (eg, customer sites) where they sometimes have strange configs, that add in global includes (eg, they put the include in machine.config, instead of the web.config for that app) or have allowOverride=false, etc.

  • GWT: Select a TreeItem with right click

  • Writing a custom iterator -- what to do if you're at the end of the array?

    - by Goose Bumper
    I'm writing a custom iterator for a Matrix class, and I want to implement the increment method, which gets called when the iterator is incremented: void MatrixIterator::increment() { // go to the next element } Suppose the iterator has been incremented too many times and now points to past the end of the matrix (i.e. past the one-past-the-end point). What is the best practice for this situation? Should I catch this with an assert, or should I just say it's the user's responsibility to keep track of where the iterator is pointing and it's none of my business?
