  • How important is W3C XHTML/CSS validation when finalizing work?

    - by Andrew G. Johnson
    Even though I always strive for complete validation these days, I often wonder if it's a waste of time. If the code runs and it looks the same in all browsers (I use browsershots.org to verify) then do I need to take it any further or am I just being overly anal? What level do you hold your code to when you create it for: a) yourself b) your clients P.S. Jeff and company, why doesn't stack overflow validate? :) EDIT: Some good insights, I think that since I've been so valid-obsessed for so long I program knowing what will cause problems and what won't so I'm in a better position than people who create a site first and then "go back and fix the validation problems" I think I may post another question on stack overflow; "Do you validate as you go or do you finish and then go back and validate?" as that seems to be where this question is going

  • Does XercesC contain an extensive logic of XMLSchema validation?

    - by seas
    Tried to implement a small XML validation tool with XercesC. For some reason I cannot use existing validators right from the box - I need some preprocessing and would like to combine it with validation in a single tool. I used DOM parser and specified DOMErrorHandler. Instead of a set of errors with detailed messages like I saw from xmllint for the same xml and xmlschema files, only one message appeared that document has a wrong structure without details. Probably, I did something wrong. But also assume XercesC doesn't contain xmllint functionality right from the box. Does anybody can give me a hint before I spent too much time? Thanks.

  • ASP.NET MVC2 - Trim white space from form submits before server-side validation?

    - by David Lively
    If I add a validation attribute: public class ProductDownloadListModel { //xxxxx-xxxxx-xxxxx [Required] [StringLength(17)] public string PSN { get; set; } public DateTime PsnExpirationDate { get; set; } public DataTable Downloads { get; set; } } and the user enters a 17-character string but includes white space on the end, I get a validation error because the string is greater than that specified by the [StringLength(17)] attribute. How can I prevent this? I'd prefer not to have to have javaScript trim the string before submits.

  • How do I clear MVC client side validation errors when a cancel button is clicked when a user has inv

    - by Sci-fi
    I have a partial view that is rendered within a main view. The partial view takes advantage of System.ComponentModel.DataAnnotations and Html.EnableClientValidation(). A link is clicked, and div containing the partial view is displayed within a JQuery.Dialog(). I then click the save button without entering any text in my validated input field. This causes the client side validation to fire as expected, and display the '*required' message beside the invalid field. When the cancel button is clicked, I want to reset the client side MVC validation back to it's default state and remove any messages, ready for when the user opens the dialog again. Is there a recommended way of doing this?

  • Given a user control with a form containing validation can I validate entirely server side?

    - by JoshBaltzell
    We have an existing User Control that was built to dynamically generate a web form for an end user. This form includes required field validators, custom validators that use server side code and Regular Expression validatiors. We now have a need to use all these validators to verify that all the needed data is entered when using a separate ordering process that cannot be validated in the same way, but has the same validation requirements before it is added to the database. I would like to use this user control to validate the input by passing it all the values and checking the validation summary. The only way I know how to do this is to render it to a page on the client side and trigger the form submit. Is there any way to populate and validate a web form entirely on the server side?

  • Connecting to IPv6 hosts when mobile and on a Surface?

    - by Cerebrate
    Specifically, at my usual location, I have an IPv6 network which connects to the Internet via a static tunnel set up to Hurricane Electric's tunnel broker ( http://www.tunnelbroker.net/ ). This works essentially perfectly, allowing inbound and outbound connectivity. Now, however, I need to connect back to host(s) on that network over IPv6 from mobile tablet(s); meaning the conditions are such that there is no guarantee or even likelihood of native IPv6 support where it happens to be at any given time, and the IPv4 address of the tablet will change on a fairly regular basis. The native Teredo support, as configured by default, functions well enough to let me ping my target hosts, but appears to have neither the reliability nor the throughput to support anything else; I have been unable to make any actual connections (trying a number of TCP-based protocols) using it. I had considered setting up an independent tunnel for the tablet(s), and using scripts to update the client endpoint IP address when it changes, but since both (a) many of the locations will be behind NAT devices over which I have no control, and (b) the option over which I do have control is an AT&T Unite hotspot which does not offer protocol 41 forwarding or respond to ICMP on its public address, this approach does not seem viable. I am additionally constrained as the mobile tablet(s) in question are Surface RTs, and as such are incapable of running, for example, AICCU client software. What is my best option to pursue to obtain IPv6 connectivity in this scenario?

  • What mobile phones are viable for a "nerdy" person? [closed]

    - by Blixt
    This community wiki is for determining a list of good mobile phone choices if you are "nerdy" (definition follows.) As a point of reference, the almost two years old N95 8GB will be used. Mostly because that's what I can most relate to since I've had it since it came out. Today, iPhone and other modern mobile phones really out-shine it in usability and interface. However, it still does everything I want it to do (and here's the definition of "nerdy"; modify as needed): Syncs contacts, calendar, tasks and mail in the background Can run multiple installable applications in the background (Google Maps with Latitude, for example) Good amount of space for music etc. Lets you develop your own little toy applications (Python; not to mention it can also run an Apache server with a public URL!) Tethering! Supports Flash (maybe not very important, but it has its uses) Has a manufacturer that believes in the nerdiness! (The people at Nokia Labs make lots of cool stuff and share early versions with the community and are generally open) A high resolution screen (at least 320x240) Special hardware features such as an accelerometer and GPS What's missing from the N95 8GB but still qualifies as good, "nerdy", qualities: 7.2 Mbit/s (or faster) internet through HSDPA or HSPA+. A good web browser that can do most of the stuff a desktop browser can (especially render sites properly and run JavaScript correctly) Touch (especially multi-touch) More special hardware features such as a compass Intuitive and fluent user interface (Shiny stuff) Ability to configure it to trust root certificates of my own choice A processor fast enough to run Quake 3! =)

  • Javascript callback on blackberry

    - by Jeff
    I'm working on a mobile project, and I have a script that is dynamically generated on the backend and then appended to the document (the html page). Desktop browsers seem to append the script correctly and call any functions in the script, however, I can't get this to happen on Blackberry phones. I know that the script is being appending because I can alert it after I append it. I just can get it to call the function in the script. For example, if I have code like this: var scriptText = document.createElement('script'); scriptText.type = 'text/javascript'; scriptText.id = 'thisScript'; scriptText.innerHTML = 'alert("hello");'; document.getElementById('idName').appendChild(scriptText); alert(document.getElementById('thisScript')); //Alerts the script element. This will alert 'hello' in desktop browsers and even the iPhone/iPodTouch, but not BlackBerry's. Anyone have any idea why? Or if there's a fix/hack?

  • Develop applications to mobiles

    - by muek
    Hi there, I have very easy question, but I simply have any idea of the answer. I have developed a small mobile-application using java, for my nokia. The problem is that when installed on my samsung the application simply crashed. Then I tried on my other nokia but different model, and I didn't got the normal behavior. So my question is, does anyone have any idea how companies that develop mobiles applications/games test their software. Does they have to have all models for all mobiles phones??

  • MVC Model Binding to a collection where collection does not begin with a 0 index

    - by FloatLeft
    I'm trying to perform remote validation on a property of an item within a collection. The validation works OK on the first item of the collection. The http request to the validation method looks like: /Validation/IsImeiAvailable?ImeiGadgets[0].ImeiNumber=123456789012345 However on the 2nd item where the url looks like below, the validation doesn't work /Validation/IsImeiAvailable?ImeiGadgets[1].ImeiNumber=123456789012345 Now I'm pretty sure the reason for this, is that binding wont work on a collection that doesn't begin with a zero index. My validation method has a signature as below: public JsonResult IsImeiAvailable([Bind(Prefix = "ImeiGadgets")] Models.ViewModels.ImeiGadget[] imeiGadget) Because I'm passing an item within a collection I have to bind like this yet what I'm really passing is just a single value. Is there anyway I can deal with this other than just binding it as a plain old query string. Thanks Edit: This is the quick fix to get the Imei variable but I'd rather use the model binding: string imeiNumber = Request.Url.AbsoluteUri.Substring(Request.Url.AbsoluteUri.IndexOf("=")+1);

  • IValidatableObject vs Single Responsibility

    - by Boris Yankov
    I like the extnesibility point of MVC, allowing view models to implement IValidatableObject, and add custom validation. I try to keep my Controllers lean, having this code be the only validation logic: if (!ModelState.IsValid) return View(loginViewModel); For example a login view model implements IValidatableObject, gets ILoginValidator object via constructor injection: public interface ILoginValidator { bool UserExists(string email); bool IsLoginValid(string userName, string password); } It seems that Ninject, injecting instances in view models isn't really a common practice, may be even an anti-pattern? Is this a good approach? Is there a better one?

  • How come verification does not include actual testing?

    - by user970696
    Having read a lot about this topic, I still did not get it. Verification should prove that you are building the product right, while validation you build the right product. But only static techniques are mentioned as being verification methods (code reviews, requirements checks...). But how can you say if its implemented correctly if you do not test it? It is said that verification checks e.g. code for its correctnes. Verification - ensure that the product meet specified requirements. Again, if the function is specified to work somehow, only by testing I can say that it does. Could anyone explain this to me please? EDIT: As Wiki says: Verification:Preparing of the test cases (based on the analysis of the requireemnts) Validation: Running of the test cases

  • ADF Mobile - Update through Web Service (with ADF Business Components)

    - by Shay Shmeltzer
    In my previous blog entry I went over the basics of exposing ADF Business Components through service interfaces, and developing a simple ADF Mobile application that access and fetches data from those services. In this entry we'll dive a bit deeper  and address an update scenario through these web service interfaces. You can see the full demo video at the end of the post. In the first steps I show how to add an explicit method execution to fetch a specific record we want to update on the second page of a flow. For an update you'll be invoking a service method and passing the record you want to update as a parameter. As in many other Web services scenarios, we need to provide a complete object of specific type to the method. The ADF Web service data control helps you here by offering an object of this type that you can drag and drop into your page. The next step is to make sure to fill that object with the values you want to update. In the demo we do this through  coding in a backing bean that shows how to use the AdfmfJavaUtilities utility. The code gets the value from one field, gets a pointer to the parallel update field, and then copy from one to the other. At the end of the bean we manually execute the call to the update method on the Web service. Here is the demo: &amp;amp;amp;amp;&amp;lt;span id=&amp;quot;XinhaEditingPostion&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; Here is the code used in the backing bean in the demo above. package a.mobile;import oracle.adfmf.amx.event.ActionEvent;import javax.el.MethodExpression;import javax.el.ValueExpression;import oracle.adfmf.amx.event.ActionEvent;import oracle.adfmf.framework.api.AdfmfJavaUtilities;import oracle.adfmf.framework.model.AdfELContext;public class backing {    public backing() {    }    public void copyAndUpdate(ActionEvent actionEvent) {        // Add event code here...        AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext();        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName.inputValue}", String.class);        ValueExpression ve3 =            AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName1.inputValue}", String.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        MethodExpression me = AdfmfJavaUtilities.getMethodExpression("#{bindings.updateDepartmentsView1.execute}", Object.class, new Class[] {});         me.invoke(adfELContext, new Object[] {});        }    }
