  • Is html font size using em still important

    - by JohnnyHTML
    In a web LOB web based SaaS product we are developing that we explicitly not support IE 6, only IE7/8, FF 3, Chrome, Opera, WebKit etc... which allow px resize as standard, is it still important to use em rather than px? Its a lot more work to consider the compute font size (size em are computed from their inheritance chain) especially when nesting html reuse components where a font-size has already been specified in an outer container.

  • javascript detect if being run in hta

    - by rjmunro
    We'd like to allow our users to download an hta file and run our web app inside it, and have certain pages detect that they are running in an hta file and offer additional features that a web app wouldn't normally have permission to do. How can I simply detect if the page is being browsed from an hta file container?

  • Maven webapp with maven-eclipse-plugin doesn't generates <dependent-module>

    - by chrsk
    I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration? Enviroment Eclipse 3.5 JEE Galileo Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200) Java version: 1.6.0_14 m2eclipse The maven-eclipse-plugin configuration <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.8</version> <configuration> <projectNameTemplate>someproject-[artifactId]</projectNameTemplate> <useProjectReferences>false</useProjectReferences> <downloadSources>false</downloadSources> <downloadJavadocs>false</downloadJavadocs> <wtpmanifest>true</wtpmanifest> <wtpversion>2.0</wtpversion> <wtpapplicationxml>true</wtpapplicationxml> <wtpContextName>someproject-[artifactId]</wtpContextName> <additionalProjectFacets> <jst.web>2.3</jst.web> </additionalProjectFacets> </configuration> </plugin> The generated files After executing the eclipse:eclipse goal, the dependent-module is not listed in my generated .settings/org.eclipse.wst.common.component, so on server booting i miss the depdencies.

  • How to load an ajax (jquery) request response progressively without waiting for it to finish?

    - by Sebastian
    I want to make a form that will use jquery to submit a list of keyword to a php file, this file could take a lot of time to load depending on the size of the keywords list. What I want to do is to load the php response into a div or container in real time without using iframes. All the ajax request I know have to wait until the request has finished before having access to the response, I need to get access to that response even when it hasn't finished so I can update the progress in real time.

    - by BritishDeveloper
    When putting code samples in my blog I would like the code to have all the appropriate colours. How can I do that? Basically if I write: foreach (ListItem item in items) { item.Text = "something"; } I want it to appear in the correct colours like it does in my Visual Studio or here at stack*overflow*. I'm bored of styling the colours of each key word manually. Is there a pre-existing javascript library I can use?

  • Fill WPF listbox with string array

    - by Archie
    Instead of adding each item one by one to the ListBox destinationList from the string array m_List like this: foreach (object name in m_List) { destinationList.Items.Add((string)name); } Is there any better way I can do it? I don't want to bind the data to the destinationList since I want to delete some entries from the ListBox later on.

  • Help with a logic problem

    - by Stradigos
    I'm having a great deal of difficulty trying to figure out the logic behind this problem. I have developed everything else, but I really could use some help, any sort of help, on the part I'm stuck on. Back story: *A group of actors waits in a circle. They "count off" by various amounts. The last few to audition are thought to have the best chance of getting the parts and becoming stars. Instead of actors having names, they are identified by numbers. The "Audition Order" in the table tells, reading left-to-right, the "names" of the actors who will be auditioned in the order they will perform.* Sample output: etc, all the way up to 10. What I have so far: using System; using System.Collections; using System.Text; namespace The_Last_Survivor { class Program { static void Main(string[] args) { //Declare Variables int NumOfActors = 0; System.DateTime dt = System.DateTime.Now; int interval = 3; ArrayList Ring = new ArrayList(10); //Header Console.Out.WriteLine("Actors\tNumber\tOrder"); //Add Actors for (int x = 1; x < 11; x++) { NumOfActors++; Ring.Insert((x - 1), new Actor(x)); foreach (Actor i in Ring) { Console.Out.WriteLine("{0}\t{1}\t{2}", NumOfActors, i, i.Order(interval, x)); } Console.Out.WriteLine("\n"); } Console.In.Read(); } public class Actor { //Variables protected int Number; //Constructor public Actor(int num) { Number = num; } //Order in circle public string Order(int inter, int num) { //Variable string result = ""; ArrayList myArray = new ArrayList(num); //Filling Array for (int i = 0; i < num; i++) myArray.Add(i + 1); //Formula foreach (int element in myArray) { if (element == inter) { result += String.Format(" {0}", element); myArray.RemoveAt(element); } } return result; } //String override public override string ToString() { return String.Format("{0}", Number); } } } } The part I'm stuck on is getting some math going that does this: Can anyone offer some guidance and/or sample code?

  • input type="text" not clickable in a jcarousel (jQuery based carousel) element

    - by AkaiKen
    Hello ! I work on a website where almost all objects are in a jCarousel element : <div> <ul id="mycarousel"> <li>object 1</li> <li>object 2</li> </ul> </div> is the "written" code, and : <div class=" jcarousel-skin-tango"> <div class="jcarousel-container jcarousel-container-horizontal" style="display: block;"> <div class="jcarousel-prev jcarousel-prev-horizontal jcarousel-prev-disabled jcarousel-prev-disabled-horizontal" style="display: block;" disabled="true"></div> <div class="jcarousel-next jcarousel-next-horizontal" style="display: block;" disabled="false"></div> <div class="jcarousel-clip jcarousel-clip-horizontal"> <ul class=" jcarousel-list jcarousel-list-horizontal" id="mycarousel" style="width: 2853px; left: 0px;"> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 1 </li> <li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-1 jcarousel-item-1-horizontal" jcarouselindex="1" style="width: 307px;"> object 2 </li> </ul> </div> </div> is the generated code (here it lacks the ultimate </div>, maybe a number of rows limitation ?). I'm sorry I can't provide a link, I work on a local server currently. It works perfectly =) but... my problem is : an <input type="text" /> won't be clickable in this environment. I tried the others type of input, radio, checkbox, file : works. But text does not. I can specify a value on my input (it's its purpose on my work : a search in a database for datas to be modified and reinjected in database). In fact, I can access to the text input by clicking-right in then left. But it's pretty 'unergonomic', and in my project it's unthinkable. Ah, and I tried to style this input with a style="z-index:1000;", no changes, I think it's not a CSS problem. Does anybody have an idea ? Thank you very much in advance.

  • Spring validation errors not displayed

    - by Art Vandelay
    I have the following situation. I have a validator to validate my command object and set the errors on a Errors object to be displayed in my form. The validator is invoked as expected and works okay, but the errors i set on the Errors objects are not displayed, when i am sent back to my form because of the validation errors. Validator: public void validate(Object obj, Errors err) { MyCommand myCommand = (MyCommand) obj; int index = 0; for (Field field : myCommand.getFields()) { if (field.isChecked()) { if ((field.getValue() == null) || (field.getValue().equals(""))) { err.rejectValue("fields[" + index + "].value", "errors.missing"); } } index++; } if (myCommand.getLimit() < 0) { err.rejectValue("limit", "errors.invalid"); } } Command: public class MyCommand { private List<Field> fields; private int limit; //getters and setters } public class Field { private boolean checked; private String name; private String value; //getters and setters } Form: <form:form id="myForm" method="POST" action="${url}" commandName="myCommand"> <c:forEach items="${myCommand.fields}" var="field" varStatus="status"> <form:checkbox path="fields[${status.index}].checked" value="${field.checked}" /> <c:out value="${field.name}" /> <form:input path="fields[${status.index}].value" /> <form:errors path="fields[${status.index}].value" cssClass="error" /></td> <form:hidden path="fields[${status.index}].name" /> </c:forEach> <fmt:message key="label.limit" /> <form:input path="limit" /> <form:errors path="limit" cssClass="error" /> </form:form> Controller: @RequestMapping(value = REQ_MAPPING, method = RequestMethod.POST) public String onSubmit(Model model, MyCommand myCommand, BindingResult result) { // validate myCommandValidator.validate(myCommand, result); if (result.hasErrors()) { model.addAttribute("myCommand", myCommand); return VIEW; } // form is okay, do stuff and redirect } Could it be that the paths i give in the validator and tag are not correct? The validator validates a command object containing a list of objects, so that's why i give a index on the list in the command object when registering an error message (for example: "fields["+index+"]".value). Or is it that the Errors object containing the errors is not available to my view? Any help is welcome and appreciated, it might give me a hint or point me in right direction.

  • Silverlight with MVVM Inheritance: ModelView and View matching the Model

    - by moonground.de
    Hello Stackoverflowers! :) Today I have a special question on Silverlight (4 RC) MVVM and inheritance concepts and looking for a best practice solution... I think that i understand the basic idea and concepts behind MVVM. My Model doesn't know anything about the ViewModel as the ViewModel itself doesn't know about the View. The ViewModel knows the Model and the Views know the ViewModels. Imagine the following basic (example) scenario (I'm trying to keep anything short and simple): My Model contains a ProductBase class with a few basic properties, a SimpleProduct : ProductBase adding a few more Properties and ExtendedProduct : ProductBase adding another properties. According to this Model I have several ViewModels, most essential SimpleProductViewModel : ViewModelBase and ExtendedProductViewModel : ViewModelBase. Last but not least, according Views SimpleProductView and ExtendedProductView. In future, I might add many product types (and matching Views + VMs). 1. How do i know which ViewModel to create when receiving a Model collection? After calling my data provider method, it will finally end up having a List<ProductBase>. It containts, for example, one SimpleProduct and two ExtendedProducts. How can I transform the results to an ObservableCollection<ViewModelBase> having the proper ViewModel types (one SimpleProductViewModel and two ExtendedProductViewModels) in it? I might check for Model type and construct the ViewModel accordingly, i.e. foreach(ProductBase currentProductBase in resultList) if (currentProductBase is SimpleProduct) viewModels.Add( new SimpleProductViewModel((SimpleProduct)currentProductBase)); else if (currentProductBase is ExtendedProduct) viewModels.Add( new ExtendedProductViewModels((ExtendedProduct)currentProductBase)); ... } ...but I consider this very bad practice as this code doesn't follow the object oriented design. The other way round, providing abstract Factory methods would reduce the code to: foreach(ProductBase currentProductBase in resultList) viewModels.Add(currentProductBase.CreateViewModel()) and would be perfectly extensible but since the Model doesn't know the ViewModels, that's not possible. I might bring interfaces into game here, but I haven't seen such approach proven yet. 2. How do i know which View to display when selecting a ViewModel? This is pretty the same problem, but on a higher level. Ended up finally having the desired ObservableCollection<ViewModelBase> collection would require the main view to choose a matching View for the ViewModel. In WPF, there is a DataTemplate concept which can supply a View upon a defined DataType. Unfortunately, this doesn't work in Silverlight and the only replacement I've found was the ResourceSelector of the SLExtensions toolkit which is buggy and not satisfying. Beside that, all problems from Question 1 apply as well. Do you have some hints or even a solution for the problems I describe, which you hopefully can understand from my explanation? Thank you in advance! Thomas
