Microsoft has recently put a release of their Code Contracts framework on DevLabs with a commercial license. We're interested on using them in our project (mostly C#, some C++/CLI) to gradually replace all the custom validation code, but I'm keen to know about the experience other people have had with it before we commit to it, specifica...
I'm wondering if it's possible to have the jQuery Validator plugin validate elements that don't yet exist in the dom when the rules are initially setup. Calling the .Rules("add", therules) method only attaches the rules to elements that currently exist in the dom. If I were to create some. The validation doesn't fire. Any thoughts? Hom...

I'm thinking of two options right now for model-base validation for an ASP.net project I'm starting: xVal (Steve Sanderson's project) and the Enterprise module that Stephen Walther uses on this page I don't really know enough to talk about the preferences as I haven't used either of them yet. Any ideas? Update Using LinqToSql for ORM ...

What should I be checking in order to validate the http header. below is my current code: // Ensure the referrer header is good if (this.Request.UrlReferrer.IsWellFormedOriginalString() && this.Request.UrlReferrer.Host.Equals(this.Request.Url.Host)) ...
I want to have client-side validation for quick response to the user without a roundtrip to the server. I also want the same validation for securing the code behind action on the business and data access layer. How do you reuse that kind of code pragmatically in ASP.NET? (note: ASP.NET, C# 3.0, .NET 3.5, Visual Studio 2008) ...
I'm using ASP.NET MVC (v1.0) on an app and want to integrate simple client-side form validation. IE: Numeric-Only fields, required fields, etc. Is there good, and potentially eye-candy fancy, method of validating in jQuery on the client that will cancel form submission on failed validation? I've perused and experimented with quite a fe...
In Java if an input argument to a method is invalid, we can throw an IllegalArgumentException (which is of type RuntimeException). In C++, there is no notion of checked and unchecked exceptions. Is there a similar exception in standard C++ which can be used to indicate a runtime exception? Or is there a common style not in the standard b...

I need to make textboxA and textboxB are required to Save, but I want to alert textboxC was not filled in. For example: textboxA and textboxB have data and the form is submitted, an alert to ...
Given the following RegEx expression, testing this on regexlib.com with the string "2rocks" produces a 'match'. However, in my .NET application, it's causing the regex validator to throw a validation error. ^(?=.*[A-Za-z])[a-zA-Z0-9@\-_\+\.]{6,32}$ If I change the string to "rocks2" in both my application and regexlib.com, I get a mat...
When developing my interfaces (contracts) and the concrete implementations of them, both the data models as well as repositories, I find myself questioning where the validation logic should go. Part of me (which tends to win out) says that the class itself should be responsible for it's own validation (string max length, date buffers, e...
At the one end of my web application I have a database table storing a load of pieces of text. In the middle I have an API that separates my application tiers. At the other end I have a user interface consisting of many TextBoxes (or input type=text form elements, if you prefer). I need the maxlength properties of the TextBoxes to be ...

I have an HTML file with a couple of external JavaScript files. Here's an example, somewhat simplified from the real HTML and JavaScript files: <head> <title>Control Page</title> <script language="JavaScript" src="control.js"></script> <script language="JavaScript"> var myWindow; var controlForm; function onPageLoad(...
I'm wondering if any best practices exist for guidelines as to what should and should not go into a validator control. My thought and practice was that it should be basic sanity checking (i.e. did the user enter all the required inputs? Is there 10 digits in the phone number, is the email address in the valid form? etc..), but I've recen...
I'm currently in charge of setting up a polling system (using PHP). Now for it to be as secure and objective as possible, it's important that a visitor can only vote once. I'm thinking of validating the polls by visitor's IP (there can be only one vote from one IP), and maybe throw in a captcha test to be sure that no bots can get in o...
Using Rails validation helpers- validates_xxx_of :the_column, :message => "my message" will generate a validation message : *the_column my message* Is there a way to turn-off the inclusion of the column name? (substitute xxx with any validation helper method) ...

I'm using Spring for form input and validation. The form controller's command contains the model that's being edited. Some of the model's attributes are a custom type. For example, Person's social security number is a custom SSN type. public class Person { public String getName() {...} public void setName(String name) {...} ...
