  • Force Decimal Regex

    - by babyangel86
    Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

  • Retain ViewData when editing variable length list

    - by Pieter
    I'm editing variable length lists and use ViewData to pass around information for filling a DropDownList. I use the method described here for editing these lists: http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/ The data for this dropdownlist comes from the database. As the ViewData is not available across requests, I currently do a new query to the database each and every time. This also happens when the ModelState is not valid and the form is redisplayed. Of course, this is less then ideal even for a light-weight query as this one. How can I retain the information from that query across requests as long as the user is editing the page with that variable length list?

  • Using the AutoComplete feature of ComboBox, while limiting values to those in the list?

    - by Schmuli
    In WinForms 2.0, a ComboBox has an Auto-Complete feature, that displays a custom Drop-Down list with only the values that start with the entered text. However, if I want to limit valid values to only those that appear in the ComboBox's list of items, I can do that by setting the DropDownStyle to DropDownList, which stops the user from entering a value. However, now I can't use the Auto-Complete feature, which requires user input. Is there another way to limit input to the list, while still allowing use of the Auto-Complete feature? Note that I have seen some custom solutions for this, but I really like the way the matching Auto-Complete items are displayed in a Drop-Down list, and sorted even though the original list may not be. EDIT: I have thought about just validating the entered value, i.e. testing user input if it is valid in, say, the TextChanged event, or even using the Validating event. The question then is what is the expected behavior? Do I clear their value (an empty value is also invalid), or do I use a default value? Closest matching value? P.s. Is there any other tags that I could add to this question?

  • How to cancel a deeply nested process

    - by Mystere Man
    I have a class that is a "manager" sort of class. One of it's functions is to signal that the long running process of the class should shut down. It does this by setting a boolean called "IsStopping" in class. public class Foo { bool isStoping void DoWork() { while (!isStopping) { // do work... } } } Now, DoWork() was a gigantic function, and I decided to refactor it out and as part of the process broke some of it into other classes. The problem is, Some of these classes also have long running functions that need to check if isStopping is true. public class Foo { bool isStoping void DoWork() { while (!isStopping) { MoreWork mw = new MoreWork() mw.DoMoreWork() // possibly long running // do work... } } } What are my options here? I have considered passing isStopping by reference, which I don't really like because it requires there to be an outside object. I would prefer to make the additional classes as stand alone and dependancy free as possible. I have also considered making isStopping a property, and then then having it call an event that the inner classes could be subscribed to, but this seems overly complex. Another option was to create a "Process Cancelation Token" class, similar to what .net 4 Tasks use, then that token be passed to those classes. How have you handled this situation? EDIT: Also consider that MoreWork might have a EvenMoreWork object that it instantiates and calls a potentially long running method on... and so on. I guess what i'm looking for is a way to be able to signal an arbitrary number of objects down a call tree to tell them to stop what they're doing and clean up and return.

  • How to detect if a form input element of type file is empty

    - by Ankur
    I have some code which reads a file through a form field of type file <input type="file" ... /> I want to give the user another option of providing a url to a file rather than having to upload it as many are already online. How can I detect when this field is empty on the server side. I am using Apache Commons FileUpload FileItemStream item = iter.next(); name = item.getFieldName(); stream = item.openStream(); if(!item.isFormField()){ if(item.toString()!=""){ .... I need to detect when item is empty. The above code doesn't work, nor does using: if(item.equals(null)){ ....

  • Validate decimal number in (known) national format

    - by Álvaro G. Vicario
    PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

  • PHP displaying error for already used Username and empty field

    - by Pixel Reaper
    I want PHP to make sure the username is not already used and also check to see if the field is empty. Sorry I am a huge noob when it comes to php. Here is my code: // Check for an Username: $dup = mysql_query("SELECT user_username FROM users WHERE user_username='".$_POST['user_username']."'"); if(mysql_num_rows($dup) >0){ $errors[] = 'Username already used.'; } else{ $un = mysqli_real_escape_string($dbc, trim($_POST['user_username'])); echo '<b>Congrats, You are now Registered.</b>'; } else { $errors[] = 'You forgot to enter your Username.'; }

  • Appropriate use of DL and DD?

    - by Ian
    I had some site templates designed for me recently. I got the final HTML code, which validates, but the structure of the document is laid out using DL-DD pairs: <dl> <dd class="some-class"> Some text. </dd> </dl> I'm not especially familiar with those tags as I've never used them much, but they don't seem intended for document structure. Am I right? Why would a designer do this?

  • What is the best regular expression for validating email addresses?

    - by acrosman
    Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.

  • How to Create A Document Type Definition

    - by DaveDev
    Hi Guys I've been creating a lot of my own custom attributes in my XHTML documents lately, and am aware that because they are custom attributes, they won't validate against the W3C standard. Isn't it true that I can specify my own DTD to make it validate? If so, can anyone tell me what's involved in doing this in an ASP.NET MVC app? Thanks Dave

  • Why PHP (script) serves more requests than CGI (compiled)?

    - by Lucas Batistussi
    I developed the following CGI script and run on Apache 2 (http://localhost/test.chtml). I did same script in PHP (http://localhost/verifica.php). Later I performed Apache benchmark using Apache Benchmark tool. The results are showed in images. include #include <stdlib.h> int main(void) { printf("%s%c%c\n", "Content-Type:text/html;charset=iso-8859-1",13,10); printf("<TITLE>Multiplication results</TITLE>\n"); printf("<H3>Multiplication results</H3>\n"); return 0; } Someone can explain me why PHP serves more requests than CGI script?

  • Validating single form field with CodeIgniter

    - by iamdadude
    Is there a quick way to validate a single form field with CodeIgniter to see whether or not that field matches a set of rules? There's the $this-form_validation-run();, but that will return either TRUE or FALSE for the whole form, and that's just not what I'm looking for. For example, if I only wanted to check if the email was valid, checking the whole form is not going to get me the result I'm looking for. I looked through the documentation but couldn't find anything like $this-form_validation-run(); that accepts one parameter and returns TRUE or FALSE if it's valid.

  • Validate a subset of or only certain elements of an XML document?

    - by Gaurav Dadhania
    I have this XML file (some of them are HUGE - thousands of elements) and I'm trying to validate certain elements of this XML file using an XSD schema. For eg. dates, etc. Now, the problem is that XSD won't let me validate just certain sections of the document. It wants definitions for EVERYTHING - and that would be quite painful. What I would like to know is that is there a way to XSD work with only certain elements of the document? I've tried any and anyAttribute to no avail. If not, how would you do this? Is there a library/script that produces a schema corresponding to an XML document which I can then modify according to my needs? Thanks,

  • iPhone: Try to send html code to a php script (but fail)

    - by Marc-André Weibezahn
    Hello all, I am trying this for an iPhone app in Xcode: create html code for a website on the fly sending it to a php-script and getting the response with this code: NSError * error = [[[NSError alloc]init]autorelease]; NSURL * phpURL = [NSURL URLWithString: @"http://www.mydomain.com/myscript.php?mywebsite= (...websitestring...) ];NSString * myResponse = [NSString stringWithContentsOfURL:phpURL encoding:NSUTF8StringEncoding error:&error]; It does not work. It should not be a problem of the php code because when I replace the websitestring which contains the html code with "hello" or something, this is accepted. (the script then creates a file "test.html" with the content I sent.) But when I put html code in it, I always get the error: Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)" UserInfo=0x322ec10 {} It seems that there are some things to consider when sending code to php? Thanks in advance!

  • PHP contact form, am I doing it wrong?

    - by decimal
    I'm learning PHP and I'm trying to write a simple email script. I have a function (checkEmpty) to check if all the forms are filled in and if the email adress is valid (isEmailValid). I'm not sure how to return true checkEmpty funciton. Here's my code: When the submit button is clicked: if (isset($_POST['submit'])) { //INSERT FORM VALUES INTO AN ARRAY $field = array ('name' => $_POST['name'], 'email' => $_POST['email'], 'message' => $_POST['message']); //CONVERT ARRAY KEYS TO VARIABLE NAMES extract ($field); checkEmpty($name, $email, $message); function checkEmpty($name, $email, $message) { global $name_error; global $mail_error; global $message_error; //CHECK IF NAME FIELD IS EMPTY if (isset($name) === true && empty($name) === true) { $name_error = "<span class='error_text'>* Please enter your name</span>"; } //CHECK IF EMAIL IS EMPTY if (isset($email) === true && empty($email) === true) { $mail_error = "<span class='error_text'>* Please enter your email address</span>"; //AND IF IT ISN'T EMPTY CHECK IF IT IS A VALID ONE } elseif (!isValidEmail($email)) { $mail_error = "<span class='error_text'> * Please enter a valid email</span>"; } //CHECK IF MESSAGE IS EMPTY if (isset($message) === true && empty($message) === true) { $message_error = "<span class='error_text'>* Please enter your message</span>"; } } // This function tests whether the email address is valid function isValidEmail($email){ $pattern = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; if (eregi($pattern, $email)) { return true; } else { return false; } } I know I shouldn't be using globals in the function, I don't know an alternative. The error messages are display beside each form element.
