  • Overridden button control escaping content. How to stop it?

    - by RemotecUk
    Hi, I've got an ASP.Net button control that I have overridden to provide different functionality. the code looks as follows.. I'm overriding the Render method to surround the control with an <a>... /// <summary> /// Render Method /// </summary> /// <param name="writer"></param> protected override void Render(HtmlTextWriter writer) { base.CssClass = "euva-button-decorated"; writer.Write("<a class=\"euva-button\">"); base.Render(writer); writer.Write("</a>"); } When I check the generated source on the page, I find that where ASP.Net has injected its click handler it does the following... <a class="euva-button"><input type="submit" name="TestButton" value="Test Button" onclick="clickOnce(this);WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;TestButton&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))" id="TestButton" class="euva-button-decorated" /></a> ... it seems to be escaping the output for the double quotes which means that the browser cannot understand the javascript. How do I make the render method not escape the injected ASP.Net client click handler ?? Note I also have my own client click handler which is declared declaratively in the page mark-up.

  • Data Access Layer, Best Practices

    - by labratmatt
    I'm looking for input on the best way to refactor the data access layer (DAL) in my PHP based web app. I follow an MVC pattern: PHP/HTML/CSS/etc. views on the front end, PHP controllers/services in the middle, and a PHP DAL sitting on top of a relational database in the model. Pretty standard stuff. Things are working fine, but my DAL is getting large (codesmell?) and becoming a bit unwieldy. My DAL contains almost all of the logic to interface with my database and is full of functions that look like this: function getUser($user_id) { $statement = "select id, name from users where user_id=:user_id"; PDO builds statement and fetchs results as an array return $array_of_results_generated_by_PDO_fetch_method; } Notes: The logic in my controller only interacts with the model using functions like the above in the DAL I am not using a framework (I'm of the opinion that PHP is a templating language and there's no need to inject complexity via a framework) I generally use PHP as a procedural language and tend to shy away from its OOP approach (I enjoy OOP development but prefer to keep that complexity out of PHP) What approaches have you taken when your DAL has reached this point? Do I have a fundamental design problem? Do I simply need to chop my DAL into a number of smaller files (logically divide it)? Thanks.

  • JQuery Post-Request question - FF doesn't get the result of the referenced php page

    - by OlliD
    Dear community, I just want to have my question posted here but just from the beginning: For a personal web project I use PHP + JQuery. Now I got stuck when I try to use the ajax posting method to send data to another php-page. I planned to have some navigational elements like next + previous on the bottom of the page by saving the user input / user given data. The code looks as follows: <div id="bottom_nav"> <div id="prev" class="flt_l"><a href="?&step=<?= $pages[$step-1] ?>">next</a></div> <div id="next" class="flt_r"><a href="?&step=<?= $pages[$step+1] ?>">previous</a></div> </div> The functionality of the page works fine. Lateron, I use the following code to sent data over via POST: $("#bottom_nav a").click( function() { alert("POST-Link: Parameter=" + $("#Parameter").val()); $.ajax( { type:"post", url:"saveParameter.php", data:"Parameter=" + $("#Parameter").val(), success: function(result) { alert(result); //$("#test").text(result); } }); }); The request itself work perfectly on IE, but on FF I'm not able to get back any result. within the PHP page, there just written: <? echo $_POST['Parameter']; ?> As IE returns the correct value, FF just provide an empty message box. I assumed that the behaviour on the -Link is different. While IE seems to handle the click event after the JS-Code execution, FF will interpret it before. My question was whether you has a solution on this regarding restructuring the code itself or using another method to reach the intened behaviour. Thanks for your assistance and recommendations, Olli

  • Which JavaScript framework for me?

    - by LeonixSolutions
    This is not to be a subjective question; nor is it intended to start a religious war. Which JavaScript framework for me? Until now, I haven't coded any JS at all (no biggy, it's just another language). I have been set in my ways and eschewed any client-side code, lest the user have JS turned off, or try to "just change this a little, to see what happens" - and then expect me to support it. So, until now it has all been server-side, with PHP and an ODBC compliant database. However, I am beginning to see advantages to client-side input validation and improved graphical experience for users which would help me to produce more professional web-based applications. I am looking for a framework which : doesn't have a steep learning curve is full-featured, although that does not mean that the one with the most features wins (remember the 80/20 rule) is mature an stable (even if still in development) integrates well with common IDEs if possible. I use NetBeans for PHP (and occasionally MS visual studio for C# (I seem to have drifted away from Eclipse)) allows me to develop web sites/apps for mobile devices support for Goggle charts (or other charting) would be a bonus has good AJAX/JSON support, but I imagine that they all do Taking that into consideration, is there a "right" framework for me, or does it not really matter? I looked briefly at JQuery and JQueryGui and liked what I saw, but I really don't have time, owing to deadlines, to try them all out and see which one suits me, much as I know that I ought to.

  • Searching a document for multiple terms in VBA?

    - by Tony
    I'm trying to create a macro to be used in Microsoft Word 2007 that will search a document for multiple keywords (string variables) located in an external Excel file (the reason for having it in an external file is that the terms will often be changed and updated). I've figured out how to search a document paragraph by paragraph for a single term and color every instance of that term, and I assumed that the proper method would be to use a dynamic array as the search term variable. The question is: how do I get the macro to create an array containing all the terms from an external file and search each paragraph for each and every term? This is what I have so far: Sub SearchForMultipleTerms() ' Dim SearchTerm As String 'declare search term SearchTerm = InputBox("What are you looking for?") 'prompt for term. this should be removed, as the terms should come from an external XLS file rather than user input. Selection.Find.ClearFormatting Selection.Find.Replacement.ClearFormatti… With Selection.Find .Text = SearchTerm 'find the term! .Forward = True .Wrap = wdFindStop .Format = False .MatchCase = False .MatchWholeWord = False .MatchWildcards = False .MatchSoundsLike = False .MatchAllWordForms = False End With While Selection.Find.Execute Selection.GoTo What:=wdGoToBookmark, Name:="\Para" 'select paragraph Selection.Font.Color = wdColorGray40 'color paragraph Selection.MoveDown Unit:=wdParagraph, Count:=1 'move to next paragraph Wend End Sub Thanks for looking!

  • 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.

  • Canonical resource for forms-based design in ASP.NET MVC?

    - by Robert Harvey
    Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)

  • Combine regular expressions for splitting camelCase string into words

    - by stou
    I managed to implement a function that converts camel case to words, by using the solution suggested by @ridgerunner in this question: Split camelCase word into words with php preg_match (Regular Expression) However, I want to also handle embedded abreviations like this: 'hasABREVIATIONEmbedded' translates to 'Has ABREVIATION Embedded' I came up with this solution: <?php function camelCaseToWords($camelCaseStr) { // Convert: "TestASAPTestMore" to "TestASAP TestMore" $abreviationsPattern = '/' . // Match position between UPPERCASE "words" '(?<=[A-Z])' . // Position is after group of uppercase, '(?=[A-Z][a-z])' . // and before group of lowercase letters, except the last upper case letter in the group. '/x'; $arr = preg_split($abreviationsPattern, $camelCaseStr); $str = implode(' ', $arr); // Convert "TestASAP TestMore" to "Test ASAP Test More" $camelCasePattern = '/' . // Match position between camelCase "words". '(?<=[a-z])' . // Position is after a lowercase, '(?=[A-Z])' . // and before an uppercase letter. '/x'; $arr = preg_split($camelCasePattern, $str); $str = implode(' ', $arr); $str = ucfirst(trim($str)); return $str; } $inputs = array( 'oneTwoThreeFour', 'StartsWithCap', 'hasConsecutiveCAPS', 'ALLCAPS', 'ALL_CAPS_AND_UNDERSCORES', 'hasABREVIATIONEmbedded', ); echo "INPUT"; foreach($inputs as $val) { echo "'" . $val . "' translates to '" . camelCaseToWords($val). "'\n"; } The output is: INPUT'oneTwoThreeFour' translates to 'One Two Three Four' 'StartsWithCap' translates to 'Starts With Cap' 'hasConsecutiveCAPS' translates to 'Has Consecutive CAPS' 'ALLCAPS' translates to 'ALLCAPS' 'ALL_CAPS_AND_UNDERSCORES' translates to 'ALL_CAPS_AND_UNDERSCORES' 'hasABREVIATIONEmbedded' translates to 'Has ABREVIATION Embedded' It works as intended. My question is: Can I combine the 2 regular expressions $abreviationsPattern and camelCasePattern so i can avoid running the preg_split() function twice?

  • Efficient way of calculating average difference of array elements from array average value

    - by Saysmaster
    Is there a way to calculate the average distance of array elements from array average value, by only "visiting" each array element once? (I search for an algorithm) Example: Array : [ 1 , 5 , 4 , 9 , 6 ] Average : ( 1 + 5 + 4 + 9 + 6 ) / 5 = 5 Distance Array : [|1-5|, |5-5|, |4-5|, |9-5|, |6-5|] = [4 , 0 , 1 , 4 , 1 ] Average Distance : ( 4 + 0 + 1 + 4 + 1 ) / 5 = 2 The simple algorithm needs 2 passes. 1st pass) Reads and accumulates values, then divides the result by array length to calculate average value of array elements. 2nd pass) Reads values, accumulates each one's distance from the previously calculated average value, and then divides the result by array length to find the average distance of the elements from the average value of the array. The two passes are identical. It is the classic algorithm of calculating the average of a set of values. The first one takes as input the elements of the array, the second one the distances of each element from the array's average value. Calculating the average can be modified to not accumulate the values, but caclulating the average "on the fly" as we sequentialy read the elements from the array. The formula is: Compute Running Average of Array's elements ------------------------------------------- RA[i] = E[i] {for i == 1} RA[i] = RA[i-1] - RA[i-1]/i + A[i]/i { for i > 1 } Where A[x] is the array's element at position x, RA[x] is the average of the array's elements between position 1 and x (running average). My question is: Is there a similar algorithm, to calculate "on the fly" (as we read the array's elements), the average distance of the elements from the array's mean value? The problem is that, as we read the array's elements, the final average value of the array is not known. Only the running average is known. So calculating differences from the running average will not yield the correct result. I suppose, if such algorithm exists, it probably should have the "ability" to compensate, in a way, on each new element read for the error calculated as far.

  • How to retrieve value from ViewData when the object is not a string?

    - by Richard77
    Hello, Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration. Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality). 1) Action public ActionResult CreateHierarchy(int? index) { if(index < PropertiesOfMyClass.Lenght) { //Other code omitted ViewData["index"] = ((index == null) ? 1 : index++); Return View(); } } 2)View <% Using(Html.BeginForm()){%> //Other Code omitted <% = Html.Hidden("Index", ViewData["index"])%> <input type = "submit" value = "Do someting"/> <%}%> I've also placed this at the bottom of the page so that I can check the value of the index, <% = ViewData["index"]%> Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this: <% = Html.Hidden("index", (int)ViewData["index"])%> It's not working either Thanks for helping

  • Which language should I pick up: VB.Net or C#

    - by magius
    I'm looking to pick up either C# or VB.Net. I'd done a fair bit of VB6 programming in the past. I'm looking at getting the book, Visual Basic .NET or C#, Which to Choose? but I'm hoping that someone has read it, or used both languages and can offer advice. Should I just RTFB? Edit: Anders Sandvig raised a valid question. I'm intending to develop ActiveX applications that will be served through IE. Edit: Given that the functionality is pretty close and my favored approach to learning is to "just build it" and solve problems by looking it up on the internet, I've decided that the choice of language will be based on how easy it is to learn it. I looked around and found sites like C# Corner that supports my approach. Personal note: I wish I could also select Seb Nilsson's response as an accepted answer as well. Thanks guys for your input! Alright, then! I admit, theoretically, this topic is subjective; but a quick tally of answers seems to skew votes heavily in C#'s favor. Anyway, I'm really after experiences like what Keith's alluding to. I'm hoping he'll return to this topic and drop us a few more gems.

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

[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?

  • problem with RenderOuterTable property for .net 4.0 controls

    - by Mario
    According to the new 4.0 framework overview, one should be able to add the attrib RenderOuterTable="false" to a control that supports the attribute and see css friendly code be spit out - in other words no html tables. To test this, I threw a login control into a basic fresh webpage with the following code: <asp:Login ID="Login1" runat="server" RenderOuterTable="false"></asp:Login> The result? Crappy html table output, which supposedly doesn't happen with this attrib set to false. Here is the output: &lt;table cellpadding=&quot;0&quot;&gt; <tr> <td align="center" colspan="2">Log In</td> </tr><tr> <td align="right"><label for="MainContent_Login1_UserName">User Name:</label></td><td><input name="ctl00$MainContent$Login1$UserName" type="text" id="MainContent_Login1_UserName" /><span id="MainContent_Login1_UserNameRequired" title="User Name is required." style="visibility:hidden;">*</span></td>... Hopefully you get the point. Anyone know how to stop these controls from outputting tables? This is super annoying.

  • Authenticating GTK app to run with root permissions

    - by Thomas Tempelmann
    I have a UI app (uses GTK) for Linux that requires to be run as root (it reads and writes /dev/disk*). Instead of requiring the user to open a root shell or use "sudo" manually every time when he launches my app, I wonder if the app can use some OS-provided API to ask the user to relaunch the app with root permissions. (Note: gtk app's can't use "setuid" mode, so that's not an option here.) The advantage here would be an easier workflow: The user could, from his default user account, double click my app from the desktop, and the app then would relaunch itself with root permission after been authenticated by the API/OS. I ask this because OS X offers exactly this: An app can ask the OS to launch an executable with root permissions - the OS (and not the app) then asks the user to input his credentials, verifies them and then launches the target as desired. I wonder if there's something similar for Linux (Ubuntu, e.g.) Update: The app is a remote operated disk repair tool for the unsavvy Linux user, and those Linux noobs won't have much understanding of using sudo or even changing their user's group memberships, especially if their disk just started acting up and they're freaking out. That's why I seek a solution that avoids technicalities like this.

  • 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? :)

    Hi, the answer to this question is probably "not possible", but let me ask regardless :) Assuming we have a very simple JAVA class that has a primary key, for example: class Person { String ssid; String name; String address; ... } Now, I want to store people in a collection, meaning I will have to override the equals method. Not a completely trivial matter, but on a bare basis I will have something along the lines of: @Override public boolean equals (Object other) { if(other==this) return true; if(!other.getClass().equals(this.getClass()) return false; Person otherPerson = (Person)other; if(this.ssid.equals(otherPerson.getSsid()) return true; } Excuse any obvious blunders, just typing this out of my head. Now, let's say later on in the application I have a ssid I obtained through user input. If I want to compare my ssid to a Person, I would have to call something like: String mySsid = getFromSomewhere(); Person myPerson = getFromSomewhere(); if(myPerson.equals(new Person(mySsid)) doSomething(); This means I have to create a convenience constructor to create a Person based on ssid (if I don't already have one), and it's also quite verbose. It would be much nicer to simply call myPerson.equals(mySsid) but if I added a string comparison to my Person equals class, that would break the symmetry property, since the String hasn't got a clue on how to compare itself to a Person. So finally, the big question, is there any way to enable this sort of "shorthand" comparisons using the overriden equals method, and without breaking the symmetry rule? Thanks for any thoughts on this!

  • Interpolating environment variables into a string in Ruby using String#scan

    - by robc
    I'm trying to interpolate environment variables into a string in Ruby and not having much luck. One of my requirements is to do something (log an error, prompt for input, whatever) if a placeholder is found in the initial string that has no matching environment variable. It looks like the block form of String#scan is what I need. Below is an irb session of my failed attempt. irb(main):014:0> raw_string = "need to replace %%FOO%% and %%BAR%% in here" => "need to replace %%FOO%% and %%BAR%% in here" irb(main):015:0> cooked_string << raw_string => "need to replace %%FOO%% and %%BAR%% in here" irb(main):016:0> raw_string.scan(/%%(.*?)%%/) do |var| irb(main):017:1* cooked_string.sub!("%%#{var}%%", ENV[var]) irb(main):018:1> done irb(main):019:1> end TypeError: cannot convert Array into String from (irb):17:in `[]' from (irb):17 from (irb):16:in `scan' from (irb):16 from :0 If I use ENV["FOO"] to manually interpolate one of those, it works fine. I'm banging my head against the desk. What am I doing wrong? Ruby is 1.8.1 on RHEL or 1.8.7 on Cygwin.

  • Exporting to CSV from MySQL via PHP in FireFox

    - by typoknig
    Hi all, I am pulling some info from a database with the following code: <input type="button" value="Export to Excel" onClick="window.navigate('breakfast_service.php?action=export')"> Here is the code for that action. <?php if ($_GET['action'] == 'export') { // Get the registration data $user = 'root'; $pass = 'billiards'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link) { die('Could not connect to database!' . mysql_error()); } mysql_select_db('breakfast', $link); $query = "SELECT * FROM registration"; $result = mysql_query($query); mysql_close($link); // format into CSV $contents = "id, school_id, first_name, last_name, email, attending, created_on\n"; $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++) { $row = mysql_fetch_array($result); $id = $row['id']; $school_id = $row['school_id']; $fname = $row['first_name']; $lname = $row['last_name']; $email = $row['email']; $attending = ($row['attending'] == 0) ? 'No' : 'Yes'; $date = $row['created_on']; $contents = $contents . "$id, $school_id, $fname, $lname, $email, $attending, $date\n"; } // return as excel file $filename = "export.csv"; header('Content-type: application/ms-excel'); header('Content-Disposition: attachment; filename='.$filename); echo $contents; } ?> This combination of code works excellent in IE, but fails to do create/download a file in Firefox or Chrome. Why?

  • Rot13 for numbers.

    - by dreeves
    EDIT: Now a Major Motion Blog Post at http://messymatters.com/sealedbids The idea of rot13 is to obscure text, for example to prevent spoilers. It's not meant to be cryptographically secure but to simply make sure that only people who are sure they want to read it will read it. I'd like to do something similar for numbers, for an application involving sealed bids. Roughly I want to send someone my number and trust them to pick their own number, uninfluenced by mine, but then they should be able to reveal mine (purely client-side) when they're ready. They should not require further input from me or any third party. (Added: Note the assumption that the recipient is being trusted not to cheat.) It's not as simple as rot13 because certain numbers, like 1 and 2, will recur often enough that you might remember that, say, 34.2 is really 1. Here's what I'm looking for specifically: A function seal() that maps a real number to a real number (or a string). It should not be deterministic -- seal(7) should not map to the same thing every time. But the corresponding function unseal() should be deterministic -- unseal(seal(x)) should equal x for all x. I don't want seal or unseal to call any webservices or even get the system time (because I don't want to assume synchronized clocks). (Added: It's fine to assume that all bids will be less than some maximum, known to everyone, say a million.) Sanity check: > seal(7) 482.2382 # some random-seeming number or string. > seal(7) 71.9217 # a completely different random-seeming number or string. > unseal(seal(7)) 7 # we always recover the original number by unsealing.
