  • License validation and calling home

    - by VitalyB
    I am developing an application that, when bought, can be activated using a license. Currently I am doing offline validation which is a bit troubling to me. I am aware there is nothing to do against cracks (i.e modified binaries), however, I am thinking to trying to discourage license-key pirating. Here is my current plan: When the user activates the software and after offline validation is successful, it tries to call home and validate the license. If home approves of the license or if home is unreachable, or if the user is offline, the license gets approved. If home is reached and tells the license is invalid, validation fails. Licensed application calls home the same way every time during startup (in background). If license is revoked (i.e pirated license or generated via keygen), the license get deactivated. This should help with piracy of licenses - An invalid license will be disabled and a valid license that was pirated can be revoked (and its legal owner supplied with new license). Pirate-users will be forced to use cracked version which are usually version specific and harder to reach. While it generally sounds good to me, I have some concerns: Users tend to not like home-calling and online validation. Would that kind of validation bother you? Even though in case of offline/failure the application stays licensed? It is clear that the whole scheme can be thwarted by going offline/firewall/etc. I think that the bother to do one of these is great enough to discourage casual license sharing, but I am not sure. As it goes in general with licensing and DRM variations, I am not sure the time I spend on that kind of protection isn't better spent by improving my product. I'd appreciate your input and thoughts. Thanks!

  • Getting started with XSD validation with C#

    - by Rosarch
    Here is my first attempt at validating XML with XSD. The XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <config xmlns="Schemas" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="config.xsd"> <levelVariant> <filePath>SampleVariant</filePath> </levelVariant> <levelVariant> <filePath>LegendaryMode</filePath> </levelVariant> <levelVariant> <filePath>AmazingMode</filePath> </levelVariant> </config> The XSD, located in "Schemas/config.xsd" relative to the XML file to be validated: <?xml version="1.0" encoding="utf-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> <xs:element name="config"> <xs:complexType> <xs:sequence> <xs:element name="levelVariant"> <xs:complexType> <xs:sequence> <xs:element name="filePath" type="xs:anyURI"> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> Right now, I just want to validate the XML file precisely as it appears currently. Once I understand this better, I'll expand more. Do I really need so many lines for something as simple as the XML file as it currently exists? The validation code in C#: public void SetURI(string uri) { XElement toValidate = XElement.Load(Path.Combine(PATH_TO_DATA_DIR, uri) + ".xml"); // begin confusion string schemaURI = toValidate.Attributes("xmlns").First().ToString() + toValidate.Attributes("xsi:noNamespaceSchemaLocation").First().ToString(); XmlSchemaSet schemas = new XmlSchemaSet(); schemas.Add("", XmlReader.Create( SOMETHING )); XDocument toValidateDoc = new XDocument(toValidate); toValidateDoc.Validate(schemas, null); // end confusion root = toValidate; } Any illumination would be appreciated.

  • MVC validation error with strongly typed view

    - by Remnant
    I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

  • Simple Form validation failing Backbone

    - by Corey Buchillon
    Im not exactly adept at coding so Im probably missing something, but my view here is failing to refuse submission when one or both of the fields are empty. I have a feeling something isnt connected right to my template for the row and the view of the form Form = Backbone.View.extend({ //form vie el: '.item-form', initialize: function(){ }, events: { 'click #additem': 'addModel' }, addModel: function(itemName, price){ // simple validation before adding to collection if (itemName !="" && price !="" ){ var item = new Item({ itemName: this.$("#item").val(), price: this.$("#price").val()}); items.add(item); $("#message").html("Please wait; the task is being added."); item.save(null, {success: function (item, response,options) { item.id= item.attributes._id.$id; item.attributes.id = item.attributes._id.$id; new ItemsView({collection: items}); $("#message").html(""); } }); this.$("#item").val(''); this.$("#price").val(''); } else { alert('Please fill in both fields'); } } }); and HTML <table class="itemTable"> <thead> <tr> <th>Item</th> <th>Price</th> <th></th> </tr> </thead> <tbody class="tableBody"> <script type="text/template" id="table-row"> <td><%= itemName %></td> <td><%= price %></td> <td><button class="complete">Complete</button> <button class="remove">Remove</button></td> </script> </tbody> </table> <form class="item-form"> <input type="text" name="item" id="item" placeholder="Item"/> <!-- goes to itemName in the template for the body --> <input type="text" name="price" id="price" placeholder="Price" /><!--goes to price in the template for the body --> <button type="button" id="additem">Add</button> </form> <div id="message"></div>

  • Comparing char for validation in C++

    /* PROGRAM: Ch6_14.cpp Written by Corey Starbird This program calculates the balance owed to a hospital for a patient.

I am working on a project and I'm having trouble figuring out why my validation for patientTypeisn't working properly. I first had double quotes, but realized that would denote strings. I changed them to single quotes, my program will compile and run now, but the while loop runs no matter what I enter, I, i, O, o, or anything else. I don't know why the while loop isn't checking the condition, seeing that I did enter one of the characters in the condition, and move on to cout. Probably a simple mistake, but I thank you in advance.

  • Spring MVC parameter validation

    - by Don
    Hi, I've defined a controller, validator and command class for a Spring 2.5 MVC application like this: public class ResourceController extends AbstractCommandController { private MessageRetriever messageRetriever; protected ModelAndView handle(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception { ResourceCommand resourceCommand = (ResourceCommand) command; // I NEED TO CHECK HERE IF COMMAND IS VALID? } public static class ResourceCommand { private String module; private String site; private String lang; // GETTERS AND SETTERS OMITTED } public static class ResourceValidator implements Validator { public boolean supports(Class clazz) { return ResourceCommand.class.isAssignableFrom(clazz); } public void validate(Object obj, Errors errors) { ValidationUtils.rejectIfEmptyOrWhitespace(errors, "module", "MODULE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "site", "SITE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "lang", "LANG_REQUIRED"); } } } I have wired these all together in the application context: <bean id="resourceController" class="com.amadeus.jcp.ui.framework.localization.ResourceController"> <property name="commandClass" value="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceCommand"/> <property name="validator"> <bean class="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceValidator"/> </property> </bean> However, I can't figure out how to actually check whether the command is valid or not - I assume the framework calls the validator, but how do I get access to the result? Incidentally, I'm using Java 1.4, so can't use any solutions that require annotations or other Java 1.5 features. Thanks, Don

  • JQuery Checkbox with Textbox Validation

    - by Volrath
    I am using Jorn's validation plugin. I have a a group of checkboxes beside a group of textboxes. The textboxes are disabled by default and will enable when the matching checkbox is checked. At least 1 checkbox has to be checked which is not a problem. However, when I check more than 2 checkboxes only 1 textbox validates. The form still submits even when the second checkbox is empty. $count = 0; while($row = mysql_fetch_array($rs)) { ?> <tr> <td> <label> <input type="checkbox" name="tDays[]" id="tDays<?php echo $count; ?>" value="<?php echo $row['promoDayID'];?>" onClick="enableTxt();" <?php if((isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) || (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours))) { echo "checked='checked'"; }?> validate="required:true" /> <?php echo $row['promoDay'];?>: </label> </td> <td align="right"> <input type="textbox" size="45" style="font-size:12px" name="tHours[]" id="tHours<?php echo $count; ?>" <?php if(isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) { echo "value='" .getHours($row['promoDayID'], $arrTDays) ."'"; } elseif (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours)) { echo "value='" .getHours($row['promoDayID'], $arrSelectedTHours). "'"; } else { echo "value='' disabled='disabled'"; }?> class="required" /> <label for="tHours[]" class="error" id="tHourserror<?php echo $count; ?>">Please enter the Trading Hour.</label> </td> </tr> <?php $count++; }//while ?> This is done using javascript: function enableTxt() { for (i = 0; i <= 7; i++) { if (document.getElementById("tDays" + i) != null && document.getElementById("tDays" + i).checked == true) { document.getElementById('tHours' + i).disabled = false; document.getElementById('tHourserror' + i).style.visibility = "visible"; } else if (document.getElementById("tDays" + i) != null) { document.getElementById('tHours' + i).disabled = "disabled"; document.getElementById('tHours' + i).value = ""; document.getElementById('tHourserror' + i).style.visibility = "hidden"; } } } Please kindly advise in detail as to how this problem can be solved. I am fairly weak in JQuery.

  • Sending an AJAX Request - Can't get to work

    - by user357944
    I'm trying to make an AJAX GET request, but I simply cannot get it to work. I want to retrieve the HTML source of example.com. I've previously used JQuery to send AJAX requests, but I use JQuery only for its AJAX capabilities so it's a waste to include the 30KB file for one task. What is it that I'm doing wrong? <script type="text/javascript"> var XMLHttpArray = [ function() {return new XMLHttpRequest()}, function() {return new ActiveXObject("Msxml2.XMLHTTP")}, function() {return new ActiveXObject("Msxml2.XMLHTTP")}, function() {return new ActiveXObject("Microsoft.XMLHTTP")} ]; function createXMLHTTPObject(){ var xmlhttp = false; for(var i=0; i<XMLHttpArray.length; i++){ try{ xmlhttp = XMLHttpArray[i](); }catch(e){ continue; } break; } return xmlhttp; } function AjaxRequest(url,method){ var req = createXMLHTTPObject(); req.onreadystatechange= function(){ if(req.readyState != 4) return; if(req.status != 200) return; return req.responseText; } req.open(method,url,true); req.send(null); } function MakeRequst(){ var result=AjaxRequest("http://example.com","get"); alert(result); } </script>

  • Javascript form validation only works in firefox

    - by Logic Artist
    Hello, I am relatively new to Javascript so I'm hoping this is a simple mistake. I building a generic form validation function that is called on the form's onSubmit. The function loops through all the form's child elements, looks for certain classes, and analyzes the contents of the appropriate fields. If it finds something missing or erroneous, it displays the appropriate error message div and returns false, thus preventing the form from being submitted to the php page. It works well in firefox 3.6.3, but in every other browser I've tested (Safari 4.0.4, Chrome 4.1, IE8) it seems to ignore the onSubmit and jump straight to the php processing page. HTML CODE: <form name='myForm' id='myForm' action='process_form.php' method='post' onSubmit="return validateRequired('myForm')"> <fieldset class="required radioset"> <label for='selection1'> <input type='radio' name='selection' id='selection1' value='1'/> Option 1 </label> <label for='selection2'> <input type='radio' name='selection' id='selection2' value='2'/> Option 2 </label> <label for='selection3'> <input type='radio' name='selection' id='selection3' value='3'/> Option 3 </label> <label for='selection4'> <input type='radio' name='selection' id='selection4' value='4'/> Option 4 </label> <div class='errorBox' style='visibility:hidden'> Please make a selection </div> </fieldset> <fieldset class="required checkset"> <label> Choice 1 <input type='checkbox' name='choices' id='choice1' value='1'/> </label> <label> Choice 2 <input type='checkbox' name='choices' id='choice2' value='2'/> </label> <label> Choice 3 <input type='checkbox' name='choices' id='choice3' value='3'/> </label> <label> Choice 4 <input type='checkbox' name='choices' id='choice4' value='4'/> </label> <div class='errorBox' style='visibility:hidden'> Please choose at least one </div> </fieldset> <fieldset class="required textfield" > <label for='textinput1'> Required Text: <input type='text' name='textinput1' id='textinput1' size='40'/> </label> <div class='errorBox' style='visibility:hidden'> Please enter some text </div> </fieldset> <fieldset class="required email textfield"> <label for='email'> Required Email: <input type='text' name='email' id='email' size='40'/> </label> <div class='errorBox' style='visibility:hidden'> The email address you have entered is invalid </div> </fieldset> <div> <input type='submit' value='submit'> <input type='reset' value='reset'> </div> </form> JAVASCRIPT CODE: function validateRequired(id){ var form = document.getElementById(id); var errors = 0; var returnVal = true; for(i = 0; i < form.elements.length; i++){ var elem = form.elements[i]; if(hasClass(elem,"required")){ /*RADIO BUTTON or CHECK BOX SET*/ if(hasClass(elem,"radioset") || hasClass(elem,"checkset")){ var inputs = elem.getElementsByTagName("input"); var check = false; for(j = 0; j < inputs.length; j++){ if(inputs[j].checked){ check = true; } } if(check == false){ errors += 1; showError(elem); } else { hideError(elem); } } /*TEXT FIELD*/ else if(hasClass(elem,"textfield")){ var input = elem.getElementsByTagName("input"); if(input[0].value == ""){ errors += 1; showError(elem); } else { hideError(elem); /*EMAIL ADDRESS*/ if(hasClass(elem,"email")){ if(isValidEmail(input[0].value) == false){ errors += 1; showError(elem); } else { hideError(elem); } } } } } } if(errors > 0){ returnVal = false; } else { returnVal = true; } return returnVal;} I know this is a lot of code to look at, but any help would be appreciated. Since it works fine in one browser, Im not sure how to start debugging. Thanks Andrew

  • Validating an XML document fragment against XML schema

    - by shylent
    Terribly sorry if I've failed to find a duplicate of this question. I have a certain document with a well-defined document structure. I am expressing that structure through an XML schema. That data structure is operated upon by a RESTful service, so various nodes and combinations of nodes (not the whole document, but fragments of it) are exposed as "resources". Naturally, I am doing my own validation of the actual data, but it makes sense to validate the incoming/outgoing data against the schema as well (before the fine-grained validation of the data). What I don't quite grasp is how to validate document fragments given the schema definition. Let me illustrate: Imagine, the example document structure is: <doc-root> <el name="foo"/> <el name="bar"/> </doc-root> Rather a trivial data structure. The schema goes something like this: <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <xsd:element name="doc-root"> <xsd:complexType> <xsd:sequence> <xsd:element name="el" type="myCustomType" /> </xsd:sequence> </xsd:complexType> </xsd:element> <xsd:complexType name="myCustomType"> <xsd:attribute name="name" use="required" /> </xsd:complexType> </xsd:schema> Now, imagine, I've just received a PUT request to update an 'el' object. Naturally, I would receive not the full document or not any xml, starting with 'doc-root' at its root, but the 'el' element itself. I would very much like to validate it against the existing schema then, but just running it through a validating parser wouldn't work, since it will expect a 'doc-root' at the root. So, again, the question is, - how can one validate a document fragment against an existing schema, or, perhaps, how can a schema be written to allow such an approach. Hope it made sense.

  • Http Modules are called on every request when using mvc/routing module

    - by MartinF
    I am developing a http module that hooks into the FormsAuthentication Module through the Authenticate event. While debugging i noticed that the module (and all other modules registered) gets hit every single time the client requests a resource (also when it requests images, stylesheets, javascript files (etc.)). This happens both when running on a IIS 7 server in integrated pipeline mode, and debugging through the webdev server (in non- integrated pipeline mode) As i am developing a website with a lot images which usually wont be cached by the client browser it will hit the modules a lot of unnessecary times. I am using MVC and its routing mechanishm (System.Web.Routing.UrlRoutingModule). When creating a new website the runAllManagedModulesForAllRequests attribute for the IIS 7 (system.webServer) section is per default set to true in the web.config, which as the name indicates make it call all modules for every single request. If i set the runAllManagedModulesForAllRequests attribute to false, no modules will get called. It seems that the reason for this is because of the routing module or mvc (dont know excactly why), which causes that the asp.net (aspx) handler never gets called and therefore the events and the modules never gets called (one time only like supposed). I tested this by trying to call "mydomain.com/Default.aspx" instead of just "mydomain.com/" and correctly it calls the modules only once like it is supposed. How do i fix this so it only calls the modules once when the page is requested and not also when all other resources are requested ? Is there some way i can register that all requests should fire the asp.net (aspx) handler, except requests for specific filetype extensions ? Of course that wont fix the problem if i choose to go with urls like /content/images/myimage123 for the images (without the extension). But i cant think of any other way to fix it. Is there a better way to solve this problem ? I have tried to set up an ignoreRoute like this routes.IgnoreRoute("content/{*pathInfo}"); where the content folder contains all the images, javascripts and stylesheets in seperat subfolders, but it doesnt seem to change anything. I can see there a many different possibilites when setting up a handler but I cant seem to figure out how it should be possible to setup one that will make it possible to use the routing module and have urls like /blog/post123 and not call the modules when requesting images, javascripts and stylesheets (etc.). Hope anyone out there can help me ? Martin

  • Extending jQuery Form Validation Script for new form fields

    - by user982124
    I have a simple HTML form that originally was a series of Questions (A1 to A5 and B1 to B3) with yes/no radio buttons like this: <tr> <td width="88%" valign="top" class="field_name_left">A1</td> <td width="12%" valign="top" class="field_data"> <input type="radio" name="CriteriaA1" value="Yes">Yes<input type="radio" name="CriteriaA1" value="No">No</td> </tr> The user could only answer either the A series of questions OR either the B series of questions, but not both. Also they must complete all questions in either the A or B series. I now have an additional series of questions - C1 to C6 - and need to extend my validation scripts to ensure the user enters either A, B or C and answers all questions within each series. My original script for just the A and B looks like this: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A _OR_ B if(isAorB()){ $("#error").html("Please complete A or B, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's if(allAorBChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorB(){ var OK = false; var Achecked = false; var Bchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if (Achecked && Bchecked){ OK = true; } }); return OK; } function allAorBChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }else{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } This worked well but I'm completely stuck at extending it to include the C series. I now have to check that the user hasn't answered any A and B, A and C and B and C questions. Everything I've tried fails to validate. Here's where I'm at right now with my new script: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A or B or C if(isAorBorC()){ $("#error").html("Please complete A or B or C, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's or all C's if(allAorBorCChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorBorC(){ var OK = false; var Achecked = false; var Bchecked = false; var Cchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(theChar == "B" && this.checked && !Achecked){ Bchecked = true; } if(theChar == "C" && this.checked && !Achecked){ Cchecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if(Achecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if(Bchecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if (Achecked && Bchecked){ OK = true; } if (Achecked && CBchecked){ OK = true; } if (Bchecked && Cchecked){ OK = true; } }); return OK; } function allAorBorCChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }elseif{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } }else{ // set the input to C $("#type").val("C"); // check _all_ c's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "C"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } Anyone see what I'm doing wrong?

  • What's an appropriate HTTP status code to return by a REST API service for a validation failure?

    - by michaeljoseph
    I'm currently returning 401 Unauthorized whenever I encounter a validation failure in my Django/Piston based REST API application. Having had a look at the HTTP Status Code Registry I'm not convinced that this is an appropriate code for a validation failure, what do y'all recommend? 400 Bad Request 401 Unauthorized 403 Forbidden 405 Method Not Allowed 406 Not Acceptable 412 Precondition Failed 417 Expectation Failed 422 Unprocessable Entity 424 Failed Dependency Update: "Validation failure" above means an application level data validation failure ie. incorrectly specified datetime, bogus email address etc.

  • ModelState.AddModelError encodes HTML

    - by NTulip
    Hi I am noticing a weird issue when using ModelState.AddModelError to validate input on my forms. The output from Html.ValidationMessage is not the true HTML value but it's encoded value and so the CSS style is not applied to the error message. Example: private string errorMessage = "<span class=\"negative\">{0}</span><br class=\"hid\" />"; ModelState.AddModelError("title", String.Format(errorMessage, "Tab title is required")); The output is shown as: <span class="field-validation-error">&lt;span class=&quot;negative&quot;&gt;URL is Required&lt;/span&gt;&lt;br class=&quot;hid&quot; /&gt;</span> This didn't use to be the case with their earlier beta's and I am not sure what approach to take here. Thanks Nick

  • Can I prevent RequiredFieldValidation from triggering against postbacks from a specific control.

    - by marcusstarnes
    I have a web form with a number of textbox controls which I've associated RequiredFieldValidator's with. I have a ValidationSummary control on the page to render any incomplete fields when I submit the page. However, I've just had to add an image upload facility to the same page, and have an 'Upload' button which I have posting back to perform the upload. I don't want this upload button to trigger the RequiredFieldValidators for the rest of the page though - I want this upload postback to be ignored as far as the validation goes. What's the best way to stop the RequiredFieldValidator's from firing when I submit this upload button on the page because at the moment, the upload won't occur unless I have first field out all of the other textbox controls on the page.

    - by rsturim
    I've got an xhtml page validating under xhtml strict doctype -- but, I getting this warning which I trying to understand -- and correct. Just, how do I locate this errant "Byte-Order Mark". I'm editing my file using Visual Studio--not sure if that helps. Warning Byte-Order Mark found in UTF-8 File. The Unicode Byte-Order Mark (BOM) in UTF-8 encoded files is known to cause problems for some text editors and older browsers. You may want to consider avoiding its use until it is better supported.
