  • CSS Forms/Input Maniuplation

    - by user983969
    input:required{ background-color:#f00; } input:required label{ color: #FF3434; } I have the above CSS code currently for my form, I want to be able to make the label red when the field is required. My input field is: <label for="frmComTelephone">Telephone</label> <input type="number" name="Telephone" id="frmComTelephone"/> But that CSS isn't working how do I solve this? 2ND problem is I have the following CSS: input:focus { background-color:yellow; } input[type="text"], input[type="date"],input[type="time"],input[type="number"],textarea,select { border-radius:5px; border-width: 1px; border-style: solid; border-color: #C6C6C6; height:41px; background-color: #FF3434; width: 100%; } But when the item is focused it doesn't change to yellow, if i remove "background-color: #FF3434;" it turns yellow on focus? Is what I am doing not able to be done? Or am I going about this wrong? Thanks

  • using the :sass filter with :css

    - by corroded
    We are currently making a widget that requires some default declared styles along with it(widget html is included by javasacript, along with the default css in style tags) but the problem is i can't "chain" haml filters. What I'm trying to do is to add an internal stylesheet along with the widget like so: <style type="text/css"> p {color: #f00;} </style> <div id="widget-goes-here"> <p>etc</p> </div> We are using haml so I tried doing it with the sass filter: :sass p :color #f00 #widget-goes-here %p etc sadly, it just generated a div with a p plus the generated css code literally on top: p {color: #f00;} paragraph here I then tried using the :css filter of haml to enclose the thing in style tags(theoretically it should then turn the paragraph text color to red): :css :sass p :color #f00 #widget-goes-here %p etc But this also failed, it did generated style tags but then it just enclosed the words :sass p :color #f00 in it(it didn't parse the sass code) We did change it to :css p {color: #f00} and it worked out fine, but I still plan on doing the styling in sass(instead of plain old css) is there a way to do this?

  • Is sending a hashed password over the wire a security hole?

    - by Ubiquitous Che
    I've come across a system that is in use by a company that we are considering partnering with on a medium-sized (for us, not them) project. They have a web service that we will need to integrate with. My current understanding of proper username/password management is that the username may be stored as plaintext in the database. Every user should have a unique pseudo-random salt, which may also be stored in plaintext. The text of their password must be concatenated with the salt and then this combined string may be hashed and stored in the database in an nvarchar field. So long as passwords are submitted to the website (or web service) over plaintext, everything should be just lovely. Feel free to rip into my understanding as summarized above if I'm wrong. Anyway, back to the subject at hand. The WebService run by this potential partner doesn't accept username and password, which I had anticipated. Instead, it accepts two string fields named 'Username' and 'PasswordHash'. The 'PasswordHash' value that I have been given does indeed look like a hash, and not just a value for a mis-named password field. This is raising a red flag for me. I'm not sure why, but I feel uncomfortable sending a hashed password over the wire for some reason. Off the top of my head I can't think of a reason why this would be a bad thing... Technically, the hash is available on the database anyway. But it's making me nervous, and I'm not sure if there's a reason for this or if I'm just being paranoid.

  • Why might ASP.NET be putting JavaScript in HTML Comment blocks, not CDATA?

    - by d4nt
    We have an ASP.NET 2.0 WebForms app that uses MS Ajax 1.0. It's working fine on all our environments (dev, test, IE6 VMs etc.). However, at the customer site the client side validation is not happening. We're currently trying to eliminate all the various factors and along the way we asked them to get their page source and send it to us, and we found something interesting. In our environment, our page has ASP.NET javascript in CDATA blocks: <script type="text/javascript"> //<![CDATA[ . . . //]]> </script> In their environment, the same code looks like this: <script type="text/javascript"> <!-- . . . //--> </script> This may be a red herring, but I'd like to eliminate it as the cause of the validation issues. Does anyone know whether specific configurations/patches/versions of ASP.NET will make it do this?

  • In ASP.NET, is it possible to output cache by host name? ie varybyhost or varbyhostheader?

    - by Pure.Krome
    Hi folks, I've got a website that has a number of host headers. Depending on the host header, the results are different - both visually (theme'd) and data. So lets imagine i have a website called 'Foo' - that returns search results (original, eh?). Now, the same code runs both sites. It is physically the same server/website (using Host Headers) :- www.foo.com www.foo.com.au Now, if i goto '.com', the site is theme'd in blue. if i goto the '.com.au' site, it's theme'd in red. And the data is different for the same search result, based on the host name (ie. us results for .com, au results for .com.au) SO .. if i wish to use OutputCaching .. can this be handled / differ by the host name? I don't want to have the first person goto the .com site .. grab the results ... and the a second person goto my .com.au .. same search data .. and get the theme and results for the .com site. Possible?

  • YUI-css problem in IE 6 and 7

    - by cvack
    If you look at the screenshot below you can see that the right menu box in red has the wrong position in IE6 and 7: <div id="doc4" class="yui-t2"> //yui-t2 = 180px on the left <div id="bd"> <div id="yui-main"> <div class="yui-b"> <div class="yui-gc"> // yui-gc 2/3, 1/3 <div class="yui-u first">content</div> // 2/3 <div class="yui-u">right menu</div> // 1/3 </div> </div> </div> <div class="yui-b">left menu</div> // 180px </div> <div id="ft">footer</div> </div> Anyone know how I can fix this problem?

  • GWT - problems with constants in css

    - by hba
    Hi, I'm new to GWT; I'm building a small sample app. I have several CSS files. I'm able to successfully use the ClientBundle and CssResource to assign styles to the elements defined in my UiBinder script. Now I'd like to take it one step further and introduce CSS constants using @def css-rule. The @def works great when I define a constant and use it in the same CSS file. However I cannot use it in another CSS file. When I try to use the @eval rule to evaluate an existing constant the compiler throws an execption: "cannot make a static reference to the non-static method ". Here is an example of what I'm trying to do: ConstantStyle.css @def BACKGROUND red; ConstantStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String BACKGROUND(); } MyStyle.css @eval BACKGROUND abc.ConstantStyle.BACKGROUND(); .myClass {background-color: BACKGROUND;} MyStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String myClass; } MyResources.java package abc; import ...; interface MyResources extends ClientBundle { @Source("ConstantStyle.css") ConstantStyle constantStyle(); @Source("MyStyle.css") MyStyle myStyle(); } Thanks in advance!

  • What is it in the CSS/DOM that prevents an input box with display: block from expanding to the size of its container

    - by Steven Xu
    Sample HTML/CSS: <div class="container"> <input type="text" /> <div class="filler"></div> </div> div.container { padding: 5px; border: 1px solid black; background-color: gray; } div.filler { background-color: red; height: 5px; } input { display: block; } http://jsfiddle.net/bPEkb/3/ Question Why doesn't the input box expand to have the same outer width as, say div.filler? That is to say, why doesn't the input box expand to fit its container like other block elements with width: auto; do? I tried checking the "User Agent CSS" in Firebug to see if I could come up with something there. No luck. I couldn't find any specific differences in CSS that I could specifically link to the input box behaving differently from the regular div.filler. Besides curiousity, I'd like to know why this is to get to the bottom of it to figure out a way to set width once and forget it. My current practice of explicitly setting the width of both input and its containing block element seems redundant and less than modular. While I'm familiar with the technique of wrapping the input element in a div then assigning to the input element negative margins, this seems quite undesirable.

  • Circle to move when mouse clicked Java

    - by Myt
    So I am really new to Java and I need a circle to move around JFrame when it's clicked, but the circle has to get random cordinates. So far this code generates a new circle every time it's clicked, but all the other circles stay there aswell, but I only need one circle to move around the frame. So maybe someone can help me a little :) public class test2 extends JFrame implements MouseListener { int height, width; public test2() { this.setTitle("Click"); this.setSize(400,400); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); addMouseListener(this); width = getSize().width; height = getSize().height; } public void paint (Graphics g) { setBackground (Color.red); g.setColor(Color.yellow); int a, b; a = -50 + (int)(Math.random()*(width+40)); b = (int)(Math.random()*(height+20)); g.fillOval(a, b, 130, 110); } public void mouseClicked(MouseEvent e) { int a, b; a = -50 + (int)(Math.random()*(width+40)); b = (int)(Math.random()*(height+20)); repaint(); } public void mouseReleased(MouseEvent e){} public void mouseEntered(MouseEvent e){} public void mouseExited(MouseEvent e){} public void mousePressed(MouseEvent e){} public static void main(String arg[]){ new test2(); } }

  • Ajax: strange behaviour while checking a textfield

    - by ilnur777
    I have a registration form with checking the available name for username field through ajax. Inputing a username into username field and pushing the "Check!" button, the script sends value to php script. Then php script replaces the username field with the username field + style like this: <input type="text" name="login" value="'.$_GET["user"].'" style="width:205; height:22; border-width:1; border-color:red; border-style:solid; background-color:rgb(255,232,230);"> So when replacing the username field in the form with its equivalent from php script and then submitting a form, it is then get to script on the page that checks whether the username field is empty or not. And it returns an error that it is empty, though after checking through ajax the username field it has value. I don't understand why it gets to empty field checking script, having the same field name and having value?

  • Weird problem with PHP mail() under Linux.

    - by Vilx-
    This is the case when it "works on my machine". Except that my machine is Windows, and the target is some sort of Linux. The idea is that the mail() function puts a newline between the MIME-Version and Content-Type headers, thus breaking the whole thing. Here's the code, simpliefied as much as possible: <?php $HTMLPart = chunk_split(base64_encode('<html><body style="color: red">Test.</body></html>')); $PlaintextPart = chunk_split(base64_encode('>>> TEST <<<')); $Headers =<<<AKAM From: "My Test" <[email protected]> Reply-To: [email protected] MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="9-1410065408-1410065408=:27514" AKAM; $Body =<<<AKAM This is a multi-part message in MIME format. --9-1410065408-1410065408=:27514 Content-Type: text/plain; charset="windows-1252" Content-Transfer-Encoding: base64 $PlaintextPart --9-1410065408-1410065408=:27514 Content-Type: text/html; charset="windows-1252" Content-Transfer-Encoding: base64 $HTMLPart --9-1410065408-1410065408=:27514-- AKAM; echo 'Try 3: '; echo mail('[email protected]', 'Testmail', $Body, $Headers) ?

  • Finding missing files by checksum

    - by grw
    Hi there, I'm doing a large data migration between two file systems (let's call them F1 and F2) on a Linux system which will necessarily involve copying the data verbatim into a differently-structured hierarchy on F2 and changing the file names. I'd like to write a script to generate a list of files which are in F1 but not in F2, i.e. the ones which weren't copied by the migration script into the new hierarchy, so that I can go back and migrate them manually. Unfortunately for reasons not worth going into, the migration script can't be modified to list files that it doesn't migrate. My question differs from this previously answered one because of the fact that I cannot rely on filenames as a comparison. I know the basic outline of the process would be: Generate a list of checksums for all files, recursing through F1 Do the same for F2 Compare the lists and generate a negative intersection of the checksums, ignoring the file names, to find files which are in F1 but not in F2. I'm kind of stuck getting past that stage, so I'd appreciate any pointers on which tools to use. I think I need to use the 'comm' command to compare the list of file checksums, but since md5sum, sha512sum and the like put the file name next to the checksum, I can't see a way to get it to bring me a useful comparison. Maybe awk is the way to go? I'm using Red Hat Enterprise Linux 5.x. Thanks.

  • Visual Basic Express 2008 Help

    - by khalidfazeli
    I have been given a task to: Develop a program where a child will be presented with picture of a fruit (one of five possible fruit) on the screen at the click of a start button. The child will then try to recognise the fruit and write its name in a specified place on the screen. On the click of a check button the name of the fruit written by the child will be checked by your program and if correct will reward the child with a suitable message. If the name presented by the child is not correct, a suitable message should be presented on a red background with the correct name of the fruit included in the message. so far I have managed to create a form with 5 different fruit pictures and a text box below them. a button at the bottom of the form then checks the results and presents a message box to tell them if they have passed or failed. Private Sub btnResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResults.Click If txtApple.Text = "APPLE" And txtOrange.Text = "ORANGES" And txtStrawberry.Text = "STRAWBERRIES" And txtGrapes.Text = "GRAPES" And txtBanana.Text = "BANANAS" Then MsgBox("Congratulations! you got it all right!", MsgBoxStyle.OkOnly) End Else MsgBox("Incorrect, please try again", MsgBoxStyle.OkOnly) End End If End Sub but I can't get it to randomise the picture of the fruit, so it only displays one fruit at a time and checks against it. Any help is appreciated. Thanks

  • How to visually reject user input in a table?

    - by FX
    In the programming of a table-based application module (i.e. the user mostly enters tabular data in an already laid-out table), how would you reject user input for a given cell? The scenario is: the user edits the cell, enters something (text, picture, ...) and you want them to notice when they finish editing (hitting enter, for example) that their entry is not valid for your given "format" (in the wider meaning: it can be that they entered a string instead of a number, that their entry is too long, too short, they include a picture while it's not acceptable, ...). I can see two different things happening: You can rather easily fit their entry into your format, and you do so, but you want them to notice it so they can change if your guess is not good enough (example: they entered "15.47" in a field that needs to be an integer, so your program makes it "15") You cannot guess what to do with their entry, and want to inform them that it's not valid. My question specifically is: what visual display can you offer to inform the user that his input is invalid? Is it preferable to refuse to leave the editing mode, or not? The two things I can imagine are: using colors (red background if invalid, yellow background for my case 1 above) when you reject an input, do something like Apple does for password entry of user accounts: you make the cell "shaking" (i.e. oscillating left and right) for one second, and keep the focus/editing in their so they don't loose what they've typed. Let's hear your suggestions. PS: This question is, at least in my thought process, somehow a continuation and a specialization of my previous question on getting users to read error messages. PPS: Made this community wiki, was that the right thing to do on this kind of question or not?

  • Change css when tab has active class

    - by Yunowork
    I'm trying to change the background colour of the <body> depending on what tab specific is active. When a tab is active, a class called 'st_view_active' is added onto the tab content. In the tab content I add a hidden div with the hex code of what my body background colour should be when that tab is active, my jQuery code looks like this: $(document).ready(function() { $(function(){ $('body').css('backgroundColor',$('.st_view_active').find('.background').text()); }); }); And my html code when the tab is active is following: <div class="tab-6 st_view st_view_active" > <div style="display:none" class="background">yellow</div> <div class="st_view_inner"> tab 6 </div> </div> So when tab6 is active the background of the body should be yellow. However, this is not working, the background colour is not changing, what am I doing wrong here? DEMO and JSfiddle Thanks PS: The red and blue square is the next and previous tab handler..

  • Is it Possible to Use Constraints on Hierarchical Data in a Self-Referential Table?

    - by pbarney
    Suppose you have the following table, intended to represent hierarchical data: +--------+-------------+ | Field | Type | +--------+-------------+ | id | int(10) | | parent | int(10) | | name | varchar(45) | +--------+-------------+ The table is self-referential in that the parent_id refers to id. So you might have the following data: +----+--------+---------------+ | id | parent | name | +----+--------+---------------+ | 1 | 0 | fruit | | 2 | 0 | vegetable | | 3 | 1 | apple | | 4 | 1 | orange | | 5 | 3 | red delicious | | 6 | 3 | granny smith | | 7 | 3 | gala | +----+--------+---------------+ Using MySQL, I am trying to impose a (self-referential) foreign key constraint upon the data to cascade on update and prevent deletion of a record if it has any "children." So I used the following: CREATE TABLE `test`.`fruit` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `parent` INT(10) UNSIGNED, `name` VARCHAR(45) NOT NULL, PRIMARY KEY (`id`), CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT ) ENGINE = InnoDB; From what I understand, this should fit my requirements. (And parent must default to null to allow insertions, correct?) The problem is, if I change the id of a record, it will not cascade: Cannot delete or update a parent row: a foreign key constraint fails (`test`.`fruit`, CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE) What am I missing? Feel free to correct me if my terminology is screwed up... I'm new to constraints.

  • Grails - Removing an item from a hasMany association List on data bind?

    - by ecrane
    Grails offers the ability to automatically create and bind domain objects to a hasMany List, as described in the grails user guide. So, for example, if my domain object "Author" has a List of many "Book" objects, I could create and bind these using the following markup (from the user guide): <g:textField name="books[0].title" value="the Stand" /> <g:textField name="books[1].title" value="the Shining" /> <g:textField name="books[2].title" value="Red Madder" /> In this case, if any of the books specified don't already exist, Grails will create them and set their titles appropriately. If there are already books in the specified indices, their titles will be updated and they will be saved. My question is: is there some easy way to tell Grails to remove one of those books from the 'books' association on data bind? The most obvious way to do this would be to omit the form element that corresponds to the domain instance you want to delete; unfortunately, this does not work, as per the user guide: Then Grails will automatically create a new instance for you at the defined position. If you "skipped" a few elements in the middle ... Then Grails will automatically create instances in between. I realize that a specific solution could be engineered as part of a command object, or as part of a particular controller- however, the need for this functionality appears repeatedly throughout my application, across multiple domain objects and for associations of many different types of objects. A general solution, therefore, would be ideal. Does anyone know if there is something like this included in Grails?

  • javascript split() array contains

    - by Mahesha999
    While learning JavaScript, I did not get why the output when we print the array returned of the Sting.split() method (with regular expression as an argument) is as explained below. var colorString = "red,blue,green,yellow"; var colors = colorString.split(/[^\,]+/); document.write(colors); //this print 7 times comma: ,,,,,,, However when I print individual element of the array colors, it prints an empty string, three commas and an empty string: document.write(colors[0]); //empty string document.write(colors[1]); //, document.write(colors[2]); //, document.write(colors[3]); //, document.write(colors[4]); //empty string document.write(colors[5]); //undefined document.write(colors[6]); //undefined Then, why printing the array directly gives seven commas. Though I think its correct to have three commas in the second output, I did not get why there is a starting (at index 0) and ending empty string (at index 4). Please explain I am screwed up here.

  • Compiling a C++ application on Windows 7, but execute it on Win2003 Server

    - by dabs
    I have a C++ application (quite complex, multiple projects) in Visual Studio 2008, that produces a single dll. Recently I switched to Windows 7, but had previously been compiling under Windows XP. Suddenly the dll in question cannot be loaded by another application, i.e. on a machine running Windows 2003 Server. I've been trying various things: I've installed the VC9.0 redistributable package on the server Also copied various .dll's from that package to the application folder The project is of course compiled in release mode When I run depends.exe on the client machine, I do get the following error: "Error: The Side-by-Side configuration information for "my_dll.dll" contains errors. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem (14001). Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." and the icon for shlwapi.dll has a red overlay icon. This didn't happen when I was compiling under WinXP, so I'm guessing that there really is no problem with the .dll's on the client machine, but somewhere there is a reference to that particular version of some dll. Does anyone know what would be the best way to resolve this? Regards, Daníel

  • java: libraries for immutable functional-style data structures

    - by Jason S
    This is very similar to another question (Functional Data Structures in Java) but the answers there are not particularly useful. I need to use immutable versions of the standard Java collections (e.g. HashMap / TreeMap / ArrayList / LinkedList / HashSet / TreeSet). By "immutable" I mean immutable in the functional sense (e.g. purely functional data structures), where updating operations on the data structure do not change the original data, but instead return a new instance of the same kind of data structure. Also typically new and old instances of the data structure will share immutable data to be efficient in time and space. From what I can tell my options include: Functional Java Scala Clojure but I'm not sure whether any of these are particularly appealing to me. I have a few requirements/desirements: the collections in question should be usable directly in Java (with the appropriate libraries in the classpath). FJ would work for me; I'm not sure if I can use Scala's or Clojure's data structures in Java w/o having to use the compilers/interpreters from those languages and w/o having to write Scala or Clojure code. Core operations on lists/maps/sets should be possible w/o having to create function objects with confusing syntaxes (FJ looks slightly iffy) They should be efficient in time and space. I'm looking for a library which ideally has done some performance testing. FJ's TreeMap is based on a red-black tree, not sure how that rates. Documentation / tutorials should be good enough so someone can get started quickly using the data structures. FJ fails on that front. Any suggestions?

I have a search, that returns results if only name field contains one word. id: name: info: type: 1 balloon big red balloon big 2 house expensive beautiful luxury 3 chicken wings deep fried wings tasty these are just random words but as an example my search can only see ex. balloon and then show info, but if i type chicken wings, it does nothing. so it possible somehow to search from columns with multiple words? this is my search code below import java.io.*; import java.sql.*; import java.util.*; class Search { public static void main(String[] args) { Scanner inp``ut = new Scanner(System.in); try { Connection con = DriverManager.getConnection( "jdbc:mysql://example/mydb", "user", "password"); Statement stmt = (Statement) con.createStatement(); System.out.print("enter search: "); String name = input.next(); String SQL = "SELECT * FROM menu where name LIKE '" + name + "'"; ResultSet rs = stmt.executeQuery(SQL); while (rs.next()) { System.out.println("Name: " +rs.getString("name")); System.out.println("Description: " + rs.getString("info") ); System.out.println("Price: " + rs.getString("Price")); } } catch (Exception e) { System.out.println("ERROR: " + e.getMessage()); } } }

  • How can I change the tags/css class of some dynamic text based on output from a helper?

    - by Angela
    I have a repeated line which outputs something like: Call John Jones in -3 days (status) I have a helper called show_status(contact,email) which will output whether that particular email had been sent to that particular contact. If it is "sent," then that entire line should show up as "strike out." Similarly, if the number of days is -3 (<0), the line should be formatted in red. Here's my hack, but there must be a cleaner way to put the logic into the controller? I hard-code a value that wraps around the lines I want formatted, and assign the value based on a separate call to the same helper: <% for call in @campaign.calls %> <% if !show_call_status(@contact,call).blank? %> <%= strike_start = '<s>'%> <%= strike_end = '</s>' %> <% end %> <p> <%= strike_start %> <%= link_to call.title, call_path(call) %> on <%= (@contact.date_entered + call.days).to_s(:long) %> in <%= interval_email(@contact,call) %> days <%= make_call(@contact,call) %> <span class='status'><%= show_call_status(@contact,call) %></span> <%= strike_end %> </p> <% end %> I guess what I'd like to do is not have the if statement in the View. Not sure how to do this.
