  • Possible to have empty values with Html For Helpers such as Html.TextBoxFor()?

    - by chobo2
    Hi Is it possible to have to make a html for helper in asp.net mvc 2.0 have a default value of "empty string" Like if I do this Html.TextBoxFor( u => u.ProductName) would render to <input id ="ProductName" name="ProdcutName" type="text" value="Jim" /> Now I don't want the textbox to display jim. I want it to display nothing. <input id ="ProductName" name="ProdcutName" type="text" value="" /> I tried to do this Html.TextBoxFor( u => u.ProductName, new { @value = " "}) but that seems to do nothing. So how can I do this. I hope you can do something like this otherwise I think these new helpers have a great flaw since now I need to use like javascript to remove them since I hardly ever want a default value in the textbox especially when I have a label right beside the textbox saying what it is.

  • JQuery Ajax returned blank data

    - by kwokwai
    Hi all, I am learning how to use JQuery to help check data availability. I have written a function in a Controller for checking data input, and the URL is like this: http://www.mywebsite.com/controllers/action/avariable but the returned data was blank. <Script language="javascript"> $(document).ready(function(){ $(document).change(function(){ var usr = $("#data\\[User\\]\\[name\\]").val(); $.post{"http://www.mywebsite.com/controllers/action/", usr, function(msg){alert(msg);} } }); }); </Script> <div id="username"> <input type=text name="data[User][name]" id="data[User][name]"> </div> Here is the code of the Action: function action($data=null){ $this->autoRender = false; $result2=$this->__avail($udata); if($result2==1) {return "OK";} else {return "NOT";} }

  • Load a single symbol from a LaTeX package

    - by Martijn
    When using the MnSymbol package, pdflatex gives two font warnings: LaTeX Font Warning: Encoding 'OMS' has changed to 'U' for symbol font (Font) 'symbols' in the math version 'normal' on input line 120. LaTeX Font Info: Overwriting symbol font 'symbols' in version 'normal' (Font) OMS/cmsy/m/n --> U/MnSymbolF/m/n on input line 120. It turns out that this is probably due to a clash with the AMSSymb package. Since I need just a few symbols from the package: is there a way to load one symbol from a package, in stead of all?

  • Java splitting string by custom regex match

    - by slikz
    I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?

  • Cakephp: Extend search capability to hasMany Relationship

    - by Chris
    I have two models: Car hasMany Passengers Passenger belongsTo Car I want to implement a search using Cake Search. The user should input a number and the searchengine should return all cars that have less than this number passengers. In my search form: echo $form->input('passengers', array('label' => 'Passengers', 'div' => false)); In my Car model: public $filterArgs = array( array('name' => 'passengers', 'type' => 'int'), ); In the controller: public $presetVars = array( array('field' => 'passengers', 'type' => 'int') } I thought of adding a function to the model that returns the number of passengers: function countPassengers(){ return(count($this->Car->Passenger)); //Not sure if this works } And how to I implement this search criteria?: return all Cars where countPassengers()<passenger

  • Unwanted character being added to string in C

    - by Church
    I have a program that gives you shipping addresses from an input file.

  • How to limit the number of post values on UpdatePanel ?

    - by Aristos
    I have notice that the UpdatePanel post every field included on the form on every trigger. But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent. When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data. So I see that a lot of traffic is happened this way. So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ? Thank you in advanced.

  • How can i initialize an array without knowing it size?

    - by Sara
    I have a situation where i have to apply a criteria on an input array and reuturn another array as output which will have smaller size based upon the filtering criteria. Now problem is i do not know the size of filtered results, so i can not initialize the array with specific value. And i do not want it to be large size will null values because i am using array.length; later on. One way is to first loop the original input array and set a counter, and then make another loop with that counter length and initialize and fill this array[]. But is there anyway to do the job in just one loop?

  • Get with the ajax data into a php file

    I'm trying to build a login system with ajax and php. I use a log-view where I then save the data in ajax which brings into my doLogin.php (php file).

  • Clearcase and java process : changing view does not apply

    - by user1432310
    i have a simple application, which receives input from a user for a CC stream name, and is suppose to return the content of a specific file from this stream repository. I have tried doing this using a simple shell script: user enters stream name, java receives stream name, runs a process which runs a script "myccscript.sh" which contains "myinput=$1; cleartool setview $myinput" (or something like that). then i try reading the file and printing it's content in the java side. BUT, after the process is finished - the view is not the view from the user input - that environment was probably only valid for the process Ive created. how do i change the clearcase view to the main java process? Thanks!

  • Command Not working in separate thread in J2me.

    - by RishiPatel
    I am creating a bluetooth application. I created a simple midlet with a exit command and i create a thread for finding the service and discovering the device. While doing so it displays a animated screen on which i added the parent commandListener for exit command. After successful connection both user is represented with greetings(Current screen calls the parent Display method setCurrent for displaying itself). This screen also have CommandListener set to the parent. Now i want to add few more commands. I Implemented the CommandLIstener Interface in this class, added few commands but the commands are not working. I dont whats wen wrong. I am giving u Code snippets to fully describle my issue : - package name Imports here public class MyMidlet extends MIDlet implements CommandListener { public CommandListener theListener; public Display theDisplay; public Command exitCommand; public MyMidlet() { // Retrieve the display for this MIDlet //Create the initial screen } public void startApp() throws MIDletStateChangeException { } public void pauseApp() { } public void destroyApp(boolean unconditional) { } public void commandAction(Command c, Displayable d) { // Determine if the exit command was selected if (c == exitCommand) { //End application here notifyDestroyed(); } else { //Start the new thread here } } } Now here is the code for the class which is invoked by the above midlet in a separate thread; package here; imports here public class MyService implements Runnable, CommandListener { private MyMidlet parent; private StreamConnection conn; private OutputStream output; private InputStream input; public Command sendCommand; private TextField messageToSend Form form; public BChatService(boolean isServer, BChatMidlet parent) { //some stuff here this.parent = parent; } public void run() { //functino for showing animation here try { input = conn.openInputStream(); output = conn.openOutputStream(); } catch (IOException e) { displayError("IO Error", "An error occurred while opening " + "the input and output streams" + "(IOException: " + e.getMessage() + ")"); try { conn.close(); } catch (Exception ex) { } return; } // Create the Form here when service is discoverd and greets the users Command sendCommand = new Command("Send", Command.ITEM, 2); exitCommand = new Command("Exit", Command.EXIT, 1); form.addCommand(exitCommand); form.addCommand(sendCommand); parent.theDisplay.setCurrent(form); form.setCommandListener(this); public void commandAction(Command c, Displayable d) { if (c == exitCommand) { // End the game parent.destroyApp(true); parent.notifyDestroyed(); } if(c == sendCommand) { form.append("SOme text here"); } } } When i select the Send command, the string doesnt append in form neither exit command works. What can be the possible cause for it?? I need to implement this functionality...Is there any other way to achieve this??

  • How to align checkboxes and their labels consistently cross-browsers

    - by One Crayon
    This is one of the minor CSS problems that plagues me constantly. How do folks around StackOverflow vertically align checkboxes and their labels consistently cross-browser? Whenever I align them right in Safari (usually using vertical-align: baseline on the input), they're completely off in Firefox and IE. Fix it in Firefox, and Safari and IE are inevitably messed up. I waste time on this every time I code a form. Here's the standard code that I work with: <form> <div> <label><input type="checkbox" /> Label text</label> </div> </form> I usually use Eric Meyer's reset, so form elements are relatively clean of overrides. Looking forward to any tips or tricks that you have to offer!

  • What scripting language would you use to put text over a generated image ?

    - by Younes
    I got this question from my cousin: "What will be the best way to create a similar working website just like: http://www.plakletters.nl". I have looked into the website and think that to start of with i'm gonna help my cousin write a script that loads all fonts installed on the system into a dropdownlist. This dropdownlist will post a font value back to the page and will create images with the input of a user that comes from a textbox. This images will have to be created server side, and I also want to give the users the ability (in the future) to lay their own text over an uploaded image, to see what the result will look like on their own image. I found some information about how to create images using php, I don't know if php can output a list of installed fonts from the system it's running on. What scripting language would you use to get this job done? Keep in mind i would just like to start with outputting some images based on user input using a scripting language.

  • How do I arbitrarily reorder lines in a text file using a Unix shell?

    - by Tim Bellis
    I've got a text file with an arbitrary number of lines, e.g.: one line some other line an additional line one more here I'd like to write a script to reorder those lines based on a given order. e.g. An input of 2 1 3 4 would swap the first and second lines. An input of 3 1 2 4 would put the 3rd line first, the 1st line second, the 2nd line third and keep the 4th line fourth. I could hack something together, but I'm wondering if there's an elegant solution? I can use either bash or ksh.

  • Form Arrays support across browsers

    - by Stomped
    I'm not even sure if form arrays is the proper term, but it looks a bit like this: <input name='element[]' type='text' /> <input name='element[]' type='text' /> Which is then retrieved in PHP as an array stored in $_POST['element'] -- in this case with 2 values. I've tested it in the browsers I have available to me, but I've never seen this before and I'm wondering is this supported pretty much in all browsers? Or is this something very old that I've just not run into? Thanks!

  • Fortran - String with unknown characters into substrings

    - by Masoud
    I am trying to put an input string into sub-string arrays. The number of data in the input file are less than 10 but unknown. The number of spaces between each data is also unclear. Example: Asd B Cwqe21 Ddsw Eww I am quite novice to Fortran, so I do not know which format I should use. My problem is that I do not know the number of data (here I assumed that there are 5), so how can I make the code work? I tried the following which did not work: CHARACTER (LEN=100), DIMENSION(10) :: string READ (1,*) (string,I=1,10) It seems that the error I got was because there was no 6th string to read and put into string(6). I tried using the "Index" to find the space, but since I do not know how many spaces are in the string, it did not help me.

  • Execution sequence inside a jquery event handler

  • Haskell: Constrain function on type Double to only work with Integers

    - by thurn
    Suppose I'm writing a function that takes a list of integers and returns only those integers in the list that are less than 5.2. I might do something like this: belowThreshold = filter (< 5.2) Easy enough, right? But now I want to constrain this function to only work with input lists of type [Int] for design reasons of my own. This seems like a reasonable request. Alas, no. A declaration that constraints the types as so: belowThreshold :: [Integer] -> [Integer] belowThreshold = filter (< 5.2) Causes a type error. So what's the story here? Why does doing filter (< 5.2) seem to convert my input list into Doubles? How can I make a version of this function that only accepts integer lists and only returns integer lists? Why does the type system hate me?
