  • C input loop for shell

    - by AustinM
    So I'm working on creating a very simple C program that just preforms shell commands. This is what I have so far: #include <stdio.h> int main() { char input[30]; fputs("$ ", stdout); fflush(stdout); fgets(input, sizeof input, stdin); system(input); } It works, but only for one command. For example if I compile and type ./cmd I get the $ prompt. If I type ls I get what I'm supposed to get. But then it exits and goes back to the regular system shell. How can I make it so after the user types a command it goes back to the "$" input.

  • jQuery Mobile focus next input on keypress

    - by user738175
    I have a jquery mobile site with a html form consisting of 4 pin entry input boxes. I want the user to be able to enter a pin in each input field without having to press the iphone keyboards "next" button. I have tried the following and although it appears to set the focus to the second input and insert the value, the keyboard disappears so the user still has to activate the required input with a tap event. $('#txtPin1').keypress(function() { $('#txtPin1').bind('change', function(){ $("#txtPin1").val($("#txtPin1").val()); }); $("#txtPin2").focus(); $("#txtPin2").val('pin2'); }); Is there a different event that I should be assigning to $("#txtPin2")? I have tried to implement http://jqueryminute.com/set-focus-to-the-next-input-field-with-jquery/ this also, but I found that it worked for android and not for iphone. Any help is greatly appreciate it.

  • htaccess on remote server issues - password prompt not accepting input

    - by pying saucepan
    EDIT: I will contact the university about my problem after labor day weekend, but I thought if someone knew a quick fix that I haven't tried, or if the problem has an obvious fix then I could hope to try my luck here, thanks! TLDR: Sorry its a long post, I thought I should be... thorough. I am having a common issue (found a dead thread through google with no solution to the same problem) with the prompt to enter in a username and password via htaccess rights, but this prompt will keep popping up asking for a username and password when trying to access my home directory on my university's server which has the .htaccess and .htpasswd files. It does not matter if I enter in correct or incorrect credentials, the prompt will keep asking me for input without displaying my home directory. Ever since I have included these ht files I have never once been able to get past the username/password no matter what I have tried, save for removing them from the directory I am trying to access (my top level directory that I own). This kind of served my original goal of making the top level directory inaccessible to casual users, but if I wanted to use this method on other places, I would want it to work as intended. And I also like it when computers do what I wish they would, so any help is appreciated. Some things I have tried: Changing the file/directory access rights: they told me to try these commands if people can't access my files cd ~/public_html find ./ -type d -exec chmod 755 {} \; find ./ -type f -exec chmod 644 {} \; enter in the single character name/pw at least twenty times in a row, no cheddar. so I changed directory with cd ~ in hopes that this would be my home directory, since my home directory contains the "public_html" directory, so logic tells me that the ~ tilde symbol is the top level directory that I have ownership of. Then I did those two commands to change the rights on the files inside, I am still having no luck. How I got to this point: I have been following the instructions given to me through my university's website for setting up my little directory. A link on how they describe how to password protect the home directory is given below: "Protect Web Directories" instructions I have everything in order except for one small detail that I feel probably does not matter. I am on windows and so I am using winSCP to remote control my allocated server space. The small detail is that as the instructions indicate (on step 3) that I should use the command htpasswd -c .htpasswd {username} where {username} is my folder that holds my allocated server space. But this command requires further input through the terminal, and unfortunately winSCP does not offer this kind of functionality. So I looked up some basic instructions on using htaccess and it is formatted correctly such that the .htaccess file appears as follows: AuthType Basic AuthName "Verify" AuthUserFile /correctpath/.htpasswd require valid-user and this file is in the root directory for my server space as well as the .htpasswd file which has only this data inside: username:password I know for sure that these two files must be formatted correctly, at least according to their tutorial, because before my path was incorrectly formatted via including some curly { braces } without knowing the correct way to do this at first. And the password prompt that shows up when accessing my directory responded by loading an error page indicating to contact OSU admin or something not important. But now that I have everything like it 'should' be. I know this because when I enter in my credentials "username and password" the prompt pops up for my username and password again and again whether or not I enter in correct information. The only exception is that if I click cancel it will direct me to a page saying that I need to enter in a username and password. Note that I am very inexperienced at server-related buisness, two days ago I couldn't have told you what a website actually consists of. So, if you use some technical jargon I may or may not need to look it up and get back to you before I actually understand what you mean, but I am a quick learner and it probably wont matter.

  • ASP.NET validation not executing in a JavaScript showModalDialog call

    - by Michael Kniskern
    I currently open a pop up window from my parent page using using a JavaScript .showModalDialog function. The pop up window contains some ASP.NET validation controls which do not display when the user clicks the ASP.NET button to submit the form. If there is an error on the page, the validation message(s) do not display, the record is not updated on the server side and the pop window closes. (The asp.net validation controls do not stop the pop up window from doing a server postback) Has anyone expereinced this behavior before and is there any way to prevent it? Here is my showModalDialong call source code: function OpenChildWindow(id) { var sFeatures = sFeatures="dialogHeight: 525px;"; sFeatures += "dialogWidth: 900px;"; sFeatures += "scroll: yes;"; sFeatures += "status: no;"; sFeatures += "resizeable: no;"; var url = "MyPopUp.aspx?ID=" + id; var childName = "ChildForm"; entryWindow = window.showModalDialog(url, childName, sFeatures); if (entryWindow == true) { window.document.getElementById("<%= btnUpdateParent.ClientID %>").click(); } } Note: When the pop up modal is closed, a ASP.NET button is "clicked" to update an ASP.NET UpdatePanel on the parent to show the changes to the record modified in the pop up window.

  • Rails validation error messages: Displaying only one per field

    - by Sergio Oliveira Jr.
    Rails has an annoying "feature" which displays ALL validation error messages associated with a given field. So for example if I have 3 validates_XXXXX_of :email, and I leave the field blank I get 3 messages in the error list. This is non-sense. It is better to display one messages at a time. If I have 10 validation messages for a field does it mean I will get 10 validation error messages if I leave it blank? Is there an easy way to correct this problem? It looks straightforward to have a condition like: If you found an error for :email, stop validating :email and skip to the other field. Ex: validates_presence_of :name validates_presence_of :email validates_presence_of :text validates_length_of :name, :in = 6..30 validates_length_of :email, :in = 4..40 validates_length_of :text, :in = 4..200 validates_format_of :email, :with = /^([^@\s]+)@((?:[-a-z0-9]+.)+[a-z]{2,})$/i <%= error_messages_for :comment % gives me: 7 errors prohibited this comment from being saved There were problems with the following fields: Name can't be blank Name is too short (minimum is 6 characters) Email can't be blank Email is too short (minimum is 4 characters) Email is invalid Text can't be blank Text is too short (minimum is 4 characters)

  • validation properties by attribute

    - by netmajor
    I create class with two property - name,link(below). I use simple property validation by Required and StringLength attribute. I bind this class object to WPF ListBox(with textBoxs). But when I have textbox empty or write words longer than 8 sign nothing happens :/ What should I do to fires ErrorMessage? Or how to implement validation in other way ? I also try use : if (value is int) { throw new ArgumentException("Wpisales stringa!!"); } But it only fires in debug mode :/ My class with implementation of attribute validation: public class RssInfo : INotifyPropertyChanged { public RssInfo() { } public RssInfo(string _nazwa, string _link) { nazwa = _nazwa; link = _link; } private string nazwa; [Required(ErrorMessage = "To pole jest obowiazkowe nAZWA")] public string Nazwa { get { return nazwa; } set { if (value != nazwa) { nazwa = value; onPropertyChanged("Nazwa"); } if (value is int) { throw new ArgumentException("Wpisales stringa!!"); } } } private string link; [Required(ErrorMessage="To pole jest obowiazkowe link")] [StringLength(8, ErrorMessage = "Link cannot be longer than 8 characters")] public string Link { get { return link; } set { if (value != link) { link = value; onPropertyChanged("Link"); } } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion private void onPropertyChanged(string propertyName) { if (this.PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } }

  • WPF - expander Collapsed event being triggered by child controls with validation

    - by Shaboboo
    I have an expander that contains an ItemsControl. The items in the itemsControl are templated, some have textboxes in them, others have checkboxes. Both have bindings that cause validation. The styling and validation is working as expected. The problem is when I first expand the expander and cause a change to either control, the expander collapses again, this is not what I want. If I repeat this a second time this does not happen. I'm not sure what is triggering this strange behaviour. I've tried setting the focus to the itemsControl when the expander expands with no luck. What is differnt the second time it's expanded? Could it be the validation? Any Ideas? XAML: <Expander Header="{Binding SubSectionName}" Padding="0" > <ItemsControl ItemsSource="{Binding ConfigSubSectionSettings}" ItemTemplateSelector="{StaticResource Settings_Selector}" /> </Expander> <!-- Templates selected by the ItemTemplateSelector --> <DataTemplate x:Key="subSection_Bool"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" > <CheckBox x:Name="chk" IsChecked="{Binding BoolValue, ValidatesOnDataErrors=True}" VerticalAlignment="Center" Margin="2" > </StackPanel > </DataTemplate> <DataTemplate x:Key="subSection_Text"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" /> <TextBox x:Name="txt" VerticalAlignment="Center" Text="{Binding StringValue, ValidatesOnDataErrors=True}" /> </StackPanel> </DataTemplate>

  • jquery form wizard validation

    - by SoulieBaby
    Hi all, I'm trying to implement a validation script (bassistance) with a jquery form wizard (http://www.jankoatwarpspeed.com/post/2009/09/28/webform-wizard-jquery.aspx) but I'm having some problems. On the page for the jquery wizard, a guy named "Tommy" came up with a piece of code to implement bassistance with the code. But for some reason I can't get it to work. It comes up saying if the field needs to be filled in etc and the next button doesn't work - which is fine, BUT, if I fill in all the fields, the next button still doesn't work.. function createNextButton(i) { var stepName = "step" + i; $("#" + stepName + "commands").append("<a href='#' id='" + stepName + "Next' class='next'>Next ></a>"); /* VALIDATION */ if (options.validationEnabled) { var stepIsValid = true; $("#" + stepName + " :input").each(function(index) { stepIsValid = !element.validate().element($(this)) && stepIsValid; }); if (!stepIsValid) { return false; } } /* END VALIDATION */ $("#" + stepName + "Next").bind("click", function(e) { $("#" + stepName).hide(); $("#step" + (i + 1)).show(); if (i + 2 == count) $(submmitButtonName).show(); selectStep(i + 1); }); } Could someone help me figure this one out? :)

  • MVC2 Client Validation isn't working when getting form from ajax call

    - by devlife
    I'm trying to use MVC2 client-side validation in a partial view that is rendered via $.get. However, the client validation isn't working. I'm not quite sure what the deal is. [Required(ErrorMessage = "Email is required")] public string Email { get; set; } <% using ( Ajax.BeginForm( new AjaxOptions { Confirm = "You sure?" } ) ) { %> <%: Html.TextBoxFor( m => m.Email, new { @class = "TextBox150" } )%> <%= Html.ValidationMessageFor( m => m.Email )%> <input type="submit" value="Add/Save" style="float: right;" /> <% } %> I'm not doing anything special to render the the partial view. Just putting the html into a div and showing it in a modal popup. On a side note, does anyone know if it's possible to submit the form with client validation without a submit button?

  • How to Persist URL parameters when CakePHP form validation fails

    - by am2605
    Hi, I'm new to cakephp and trying to write a simple app with it, however I'm stuck with some form validation issues. I have a model named "Person" which hasMany "PersonSkill" objects. To add a "PersonSkill" to a person, I have set it up to call a url like this: http://localhost/myapp/person_skills/add/person_id:3 I have been passing through the person_id because I want to display the name of the person we are adding the skills for. My issue is if the validation fails, the person_id parameter is not persisted to the next request, so the person's name is not displayed. The add method on the controller looks like this: function add() { if (!empty($this->data)) { if ($this->PersonSkill->save($this->data)) { $this->Session->setFlash('Your person has been saved.'); $this->redirect(array('action' => 'view', 'id' => $this->PersonSkill->id)); } } else { $this->Person->id = $this->params['named']['person_id']; $this->set('person', $this->Person->read()); } } In my person_skill add.ctp I set a hidden field which holds the person_id, eg: echo $form->input('person_id', array('type'=>'hidden','value'=>$person['Person']['id'])); Is there a way to persist the person_id url parameter when form validation fails, or is there a better way to do this that I'm missing completely? Any advice would be greatly appreciated.

  • jQuery Validation plugin results in empty AJAX POST

    - by user305412
    Hi, I have tried to solve this issue for at couple of days with no luck. I have a form, where I use the validation plugin, and when I try to submit it, it submits empty vars. Now, if I remove the validation, everything works fine. Here is my implementation: $(document).ready(function(){ $("#myForm").validate({ rules: { field1: { required: true, minlength: 5 }, field2: { required: true, minlength: 10 } }, messages: { field1: "this is required", field2: "this is required", }, errorLabelContainer: $("#validate_msg"), invalidHandler: function(e, validator) { var errors = validator.numberOfInvalids(); if (errors) { $("#validate_div").show(); } }, onkeyup: false, success: false, submitHandler: function(form) { doAjaxPost(form); } }); }); function doAjaxPost(form) { // do some stuff $(form).ajaxSubmit(); return false; } As I wrote this does not work when I have my validation, BUT if I remove that, and just add an onsubmit="doAjaxPost(this.form); return false"; to my HTML form, it works - any clue??? Now here is the funny thing, everything works as it should in Safari, but not in firefox 3.6.2 (Mac OS X)!

  • wpf & validation application block > message localization > messageTemplateResource Name&Type

    - by Shaboboo
    I'm trying to write validation rules for my data objects in a WPF application. I'm writing them in the configuration file, and so far they are working fine. I'm stumped on how to localize the messages using messageTemplateResourceName and messageTemplateResourceType. What I know is that the strings can be writen in a resource file, given a name and referenced by that name. I get the idea, but i haven't been able to make this work. <ruleset name="Rule Set"> <properties> <property name="StringValue"> <validator lowerBound="0" lowerBoundType="Ignore" upperBound="25" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="msg1" messageTemplateResourceType="Resources" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.EnterpriseLibrary.Validation" name="String Length Validator" /> </property> </properties> </ruleset> Where is the resource file and what value do I pass to messageTemplateResourceType? I have tried writing the messages in the shell project's resource file but no sucess trying to retrieve the value. I only get the default built-in message. I've tried messageTemplateResourceType="typeof(Resources)" messageTemplateResourceType="Resources" messageTemplateResourceType="Resources.resx" messageTemplateResourceType="typeof(Shell)" messageTemplateResourceType="Shell" messageTemplateResourceType="Shell, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" I've also tried adding a new resource file in the shell project, and adding a resource file to the data object's library. I'm all out of ideas Does anyone have any suggestions? I'm not even married to the idea of resource files, so if there are other ways to localize these messages I'd love to know! thanks

  • ASP.NET MVC Conditional validation

    - by Peter Stegnar
    How to use data annotations to do a conditional validation on model? For example, lets say we have the following model (Person and Senior): public class Person { [Required(ErrorMessage = "*")] public string Name { get; set; } public bool IsSenior { get; set; } public Senior Senior { get; set; } } public class Senior { [Required(ErrorMessage = "*")]//this should be conditional validation, based on the "IsSenior" value public string Description { get; set; } } And the following view: <%= Html.EditorFor(m => m.Name)%> <%= Html.ValidationMessageFor(m => m.Name)%> <%= Html.CheckBoxFor(m => m.IsSenior)%> <%= Html.ValidationMessageFor(m => m.IsSenior)%> <%= Html.CheckBoxFor(m => m.Senior.Description)%> <%= Html.ValidationMessageFor(m => m.Senior.Description)%> I would like to be the "Senior.Description" property conditional required field based on the selection of the "IsSenior" propery (true - required). How to implement conditional validation in ASP.NET MVC 2 with data annotations? UPDATE Found nice solution. Look below.

  • Disable validation in an object in Ruby on Rails

    - by J. Pablo Fernández
    I have an object which whether validation happens or not should depend on a boolean, or in another way, validation is optional. I haven't found a clean way to do it. What I'm currently doing is this (disclaimer: you cannot unsee, leave this page if you are too sensitive): def valid? if perform_validation super else super # Call valid? so that callbacks get called and things like encrypting passwords and generating salt in before_validation actually happen errors.clear # but then clear the errors true # and claim ourselves to be valid. This is super hacky! end end Any better ways? Before you point to the :if argument of many validations, this is for a user model which is using authlogic so it has a lot of validation rules. You can stop reading here if you belive me. If you don't, authlogic already sets some :ifs like: :if => :email_changed? which I have to turn into :if => Proc.new {|user| user.email_changed? and user.perform_validation} and in some other cases, since I'm also using authlogic-oid (OpenID) I just don't have control over the :if, authlogic-oid sets it in a way I cannot change it (in time) without further monkey patching. So I have to override seemingly unrelated functions, catch exceptions if a method doesn't exist, etc. The previous hacky solution if the best of my two attempts.

  • PHP form validation function

    - by Barbs
    I am currently writing some PHP form validation (I have already validated clientside) and have some repetitive code that I think would work well in a nice little PHP function. However I have having trouble getting it to work. I'm sure it's just a matter of syntax but I just can't nail it down. Any help appreciated. //Validate phone number field to ensure 8 digits, no spaces. if(0 === preg_match("/^[0-9]{8}$/",$_POST['Phone']) { $errors['Phone'] = "Incorrect format for 'Phone'"; } if(!$errors) { //Do some stuff here.... } I found that I was writing the validation code a lot and I could save some time and some lines of code by creating a function. //Validate Function function validate($regex,$index,$message) { if(0 === preg_match($regex,$_POST[$index],$message) { $errors[$index] = $message; } And call it like so.... validate("/^[0-9]{8}$/","Phone","Incorrect format for Phone"); Can anyone see why this wouldn't work? Note I have disabled the client side validation while I work on this to try to trigger the error, so the value I am sending for 'Phone' is invalid.

  • validation in javascript - remove the error msg on focus

    - by fusion
    i'm not very well-versed with javascript, so please bear with me. i've a form in which i validate the controls with javascript. the error is displayed when the fields are empty via a div, but when i focus and type something in the textbox, the div should go away. but the error div doesn't and even if i type something valid, it still displays the div. i'd like to know where am i going wrong with this script: <script type="text/javascript"> var err = document.getElementById("errmsg"); function checkInput(inPut) { if (inPut.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); inPut.focus(); return false; } else { return true; } } function checkTextBox(textBox) { if (textBox.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); textBox.focus(); return false; } else if (!checkValidity(textBox.getValue())) { err.setStyle('display', 'block'); err.setTextValue("Please enter a valid email address!"); textBox.focus(); return false; } else { return true; } } . . . <div id="errmsg" class="invalid" style="display:none;"></div> <br /> . . . <input type="text" tabindex="1" name="name" id="name" class="input_contact" onblur="checkInput(this);"/> <br /> . . . <input type="text" tabindex="2" name="email" id="email" class="input_contact" onblur="checkTextBox(this);"/> <br /> it's a form in facebook app but while the fbjs works, i assume there's a problem with my basic javascript.

  • ASP.Net MVC Ajax form with jQuery validation

    - by Tomas Lycken
    I have an MVC view with a form built with the Ajax.BeginForm() helper method, and I'm trying to validate user input with the jQuery Validation plugin. I get the plugin to highlight the inputs with invalid input data, but despite the invalid input the form is posted to the server. How do I stop this, and make sure that the data is only posted when the form validates? My code The form: <fieldset> <legend>leave a message</legend> <% using (Ajax.BeginForm("Post", new AjaxOptions { UpdateTargetId = "GBPostList", InsertionMode = InsertionMode.InsertBefore, OnSuccess = "getGbPostSuccess", OnFailure = "showFaliure" })) { %> <div class="column" style="width: 230px;"> <p> <label for="Post.Header"> Rubrik</label> <%= Html.TextBox("Post.Header", null, new { @style = "width: 200px;", @class="text required" }) %></p> <p> <label for="Post.Post"> Meddelande</label> <%= Html.TextArea("Post.Post", new { @style = "width: 230px; height: 120px;" }) %></p> </div> <p> <input type="submit" value="OK!" /></p> </fieldset> The JavaScript validation: $(document).ready(function() { // for highlight var elements = $("input[type!='submit'], textarea, select"); elements.focus(function() { $(this).parents('p').addClass('highlight'); }); elements.blur(function() { $(this).parents('p').removeClass('highlight'); }); // for validation $("form").validate(); }); EDIT: As I was getting downvotes for publishing follow-up problems and their solutions in answers, here is also the working validate method... function ajaxValidate() { return $('form').validate({ rules: { "Post.Header": { required: true }, "Post.Post": { required: true, minlength: 3 } }, messages: { "Post.Header": "Please enter a header", "Post.Post": { required: "Please enter a message", minlength: "Your message must be 3 characters long" } } }).form(); }

  • Realtek HD Audio 5.1 Optical Input (from Xbox 360)

    - by Shevek
    I'm trying to connect up my Xbox 360 digital audio to my 5.1 speakers via my PC (my LCD has dual input, DVI for the PC, D-SUB for the Xbox). The motherboard has a Realtek ALC888 chipset and I have a 5.1 speaker system connected via 3 x 3.5mm jacks (FR/FL, RR/RL, C/LFE) and I get full 5.1 output from the PC. I have connected the optical audio cable from the Xbox to the Optical In on the motherboard's backplate. With the Xbox in Digital Stereo mode I get 2 channel audio from the Xbox, through the PC, to the speakers. With the Xbox in Dolby Digital 5.1 mode I get no sound at all. I have the latest Realtek drivers installed in Win 7 32-bit. Questions: Is it possible to use the full 5.1 DD from the Xbox? If so, am I missing some option(s) in the Realtek setup? Do I need some other piece of software to do this? (AC3Filter or FFDShow perhaps) Many thanks

  • Choice of Input / music / graphics libraries for an indie game - what factors should I consider?

    - by RusselMeMan
    I was wondering which tools (grapics-sound-input libraries, game engine libraries) that the following indie games used: Braid Superbrothers: S&S Super Meat Boy Limbo Fez (I know this one is XNA) Also, what is in common use in production games? My guess for game development in C++ is: -DirectX is most common for  Windows games -SDL or SDL+OpenGL is most common for  Linux games -OpenGL + Apple APIs are most common for OSX development What do most indie game projects use? If I wanted to casually build my own game for fun in C++ with the idea of possibly releasing it to Steam or something someday, is there anything I should be concerned about if I make it with DirectX for music/sound/input and build my own game engine? Thanks!

  • Audio input problem in Ubuntu 9.10

    - by Andrea Ambu
    My audio input is a mix of my mic output and my sound card output. I'd like it to be just my mic output. I was able to do so in Ubuntu 9.04 but the interface is 9.10 is totally changed and I tried every my creativity was able to think. It's really annoying when talking to other people over the internet because they keep hearing their voice back. I'm not sure I explained it in clear way so I'll give you an example: What I do: I put an mp3 on play or a video on youtube then open a recorder and start to talk on my mic. What happens: both my voice and audio from mp3/youtube get reordered, even if I put headphones volume to 0 (via hardware). What I'd like to happen: Only my voice should be recorded. I'm sure I'm missing some technical term, but that's the problem and I'd like to solve it in Ubuntu 9.10, any idea?

  • Detect whether or not a specific attribute was valid on the model

    - by Sir Code-A-Lot
    Having created my own validation attribute deriving from System.ComponentModel.DataAnnotations.ValidationAttribute, I wish to be able to detect from my controller, whether or not that specific attribute was valid on the model. My setup: public class MyModel { [Required] [CustomValidation] [SomeOtherValidation] public string SomeProperty { get; set; } } public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // Custom validation logic here } } Now, how do I detect from the controller whether validation of CustomValidationAttribute succeeded or not? I have been looking at the Exception property of ModelError in the ModelState, but I have no way of adding a custom exception to it from my CustomValidationAttribute. Right now I have resorted to checking for a specific error message in the ModelState: public ActionResult PostModel(MyModel model) { if(ModelState.Where(i => i.Value.Errors.Where((e => e.ErrorMessage == CustomValidationAttribute.SharedMessage)).Any()).Any()) DoSomeCustomStuff(); // The rest of the action here } And changed my CustomValidationAttribute to: public class CustomValidationAttribute : ValidationAttribute { public static string SharedMessage = "CustomValidationAttribute error"; public override bool IsValid(object value) { ErrorMessage = SharedMessage; // Custom validation logic here } } I don't like relying on string matching, and this way the ErrorMessage property is kind of misused. What are my options?

  • ASP.NET MVC2 Model Validation Fails with Non-US Date Format

    - by 81bronco
    I have a small MVC2 app that displays in two cultures: en-US and es-MX. One portion contains a user input for a date that is pre-populated with the current date in the Model. When using en-US, the date field is displayed as MM/dd/yyyy and can be changed using the same format without causing any validation errors. When using es-MX, the date field is displayed as dd/MM/yyyy, but when the date is edited in this format, the server-side validation fails with the message: The value '17/05/1991' is not valid for The Date. One of the first things that jumps out at me about that message is that it is not localized. Both the message itself (which I do not think I can control) and the Display Name of the field (which I can control and is localized in my code). Should be displaying in a localized format. I have tried stepping through the code to see exactly where the validation is failing, but it seems to be happening inside some of the compiled MVC or DataAnnotations code that I cannot see. Application details: IIS6, ASP.NET 3.5 (C#), MVC 2 RTM Sample Model Code: public class TestVieModel{ [LocalizedDisplayNameDisplayName("TheDateDisplayName", NameResourceType=typeof(Resources.Model.TestViewModel))] [Required(ErrorMessageResourceName="TheDateValidationMessageRequired", ErrorMessageResourceType=typeof(Resources.Model.TestViewModel))] [DataType(DataType.Date)] public DateTime TheDate { get; set; } } Sample Controller Action Code: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Save(TestViewModel model) { if(ModelState.IsValid) { // <--- Always is false when using es-MX and a date foramtted as dd/MM/yyyy. // Do other stuff return this.View("Complete", model); } // Validation failed, redisplay the form. return this.View("Enter", model); } Sample View Code: <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<HispanicSweeps.Web.Model.LosMets.EnterViewModel>" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Test</title> </head> <body> <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.DateOfBirth) %> </div> <div class="editor-field"> <%= Html.EditorFor(model => model.DateOfBirth) %> <%= Html.ValidationMessageFor(model => model.DateOfBirth) %> </div> <p><input type="submit" value="Save" /></p> </fieldset> <% } %> </body> </html>

  • PayPal IPN validation

    - by denis_n
    Following is from PayPal Order Management Integration Guide: Processing the PayPal Response to Your Postback PayPal responds to your postbacks with a single word in the body of the response: VERIFIED or INVALID. When you receive a VERIFIED postback response, perform the following checks on data in the IPN: Check that the payment_status is Completed. If the payment_status is Completed, check the txn_id against the previous PayPal transaction that you processed to ensure it is not a duplicate. Check that the receiver_email is an email address registered in your PayPal account. Check that the price, carried in mc_gross, and the currency, carried in mc_currency, are correct for the item, carried in item_name or item_number. After you complete the above checks, notification validation is complete. You can update your database with the information provided, and you can initiate other appropriate automated back-end processing. <form action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_cart" /> <input type="hidden" name="upload" value="1" /> <input type="hidden" name="business" value="GXLC9H9VFPLQE"> ..... <input type="submit" name="Submit" value="Submit" /> </form> In step 3 I should check receiver_email, but I don't want to. I don't want to keep my paypal account email in my application. My question is: can I check business variable instead?

  • An alternative to reading input from Java's System.in

    - by dvanaria
    I’m working on the UVa Online Judge problem set archive as a way to practice Java, and as a way to practice data structures and algorithms in general. They give an example input file to submit to the online judge to use as a starting point (it’s the solution to problem 100). Input from the standard input stream (java.lang.System.in) is required as part of any solution on this site, but I can’t understand the implementation of reading from System.in they give in their example solution. It’s true that the input file could consist of any variation of integers, strings, etc, but every solution program requires reading basic lines of text input from System.in, one line at a time. There has to be a better (simpler and more robust) method of gathering data from the standard input stream in Java than this: public static String readLn(int maxLg) { byte lin[] = new byte[maxLg]; int lg = 0, car = -1; String line = “”; try { while (lg < maxLg) { car = System.in.read(); if ((car < 0) || (car == ‘\n’)) { break; } lin[lg++] += car; } } catch (java.io.IOException e) { return (null); } if ((car < 0) && (lg == 0)) { return (null); // eof } return (new String(lin, 0, lg)); } I’m really surprised by this. It looks like something pulled directly from K&R’s “C Programming Language” (a great book regardless), minus the access level modifer and exception handling, etc. Even though I understand the implementation, it just seems like it was written by a C programmer and bypasses most of Java’s object oriented nature. Isn’t there a better way to do this, using the StringTokenizer class or maybe using the split method of String or the java.util.regex package instead?
