  • A beginner's JSF question about form validation

    - by Nitesh Panchal
    Hello, I am having a form and many input elements in that. I want certain fields to be validated, so i keep validateLenth etc on those. And i want some fields to not be validated. For example, i have contact information and address information both on the same page. I want to treat contact information as one group. So if some fields are invalid they should not be submitted and address information to be independent of contact information. Thus, if address information is corrected it should be submitted. I have one form only on the page but two buttons, one for address and one for contact. Simply put :- What is the equivalent of validationGroup of Asp.Net in JSF?

  • Appropriate high level language to deal with binary data

    - by fortran
    Hi, I need to write a small tool that parses a textual input and generates some binary encoded data. I would prefer to stay away from C and the like, in favour of a higher level, (optionally) safer, more expressive and faster to develop language. My language of choice for this kind of tasks usually is Python, but for this case dealing with binary raw data can be problematic if one isn't very careful with the numbers being promoted to bignums, sign extensions and such. Ideally I would like to have records with named bitfields that are portable to be serialised in a consistent manner. (I know that there's a strong point in doing it in a language I already master, although it isn't optimal, but I think this could be a good opportunity to learn something new). Thanks.

  • Beginning android: how to map a string to a list

    - by user569421
    I just finished the NotepadV1-3 tutorial for Android apps, and I was thinking of creating my own inventory app for fun, which for now basically consists of a list of names (such as "DVD" or "Grocery"), each of which can be clicked, which will bring up another specific list associated with that name. However, with the SQLiteDatabase.insert(..) method, the ContentValue can only take (among many others) "String, String" as argument, and I can't figure out how to input into the database a list of Strings associated with a particular key. I'm having trouble researching on how to resolve this as I am not that familiar with SQL. What would be the best way to store a key with its associated list of Strings? Any pointers and suggestions are appreciated! Android newb :[

  • Can I add elements to a Java GUI?

    - by Asj
    I want to know how I can make a java program where an unknown amount of objects can be added to a GUI depending on user input. I can program in objects one at a time within the program, but I haven't seen a more dynamic program. Can I do that with Java? If not, what can I do it with? For more information, here's a picture. http://i6.photobucket.com/albums/y223/Asj127/CapProjIdea.jpg There can be more than one question per question block, and each question can have it's own question block.

  • How to skip interstitial in a django view if a user hits the back button?

    - by Jose Boveda
    I have an application with an interstitial page to hold the user while an intensive operation runs in the background (takes anywhere from 30 secs to 1 minute). Once the operation is done, the user is redirected to the results page. Once on the result page, typical user behavior is to hit the 'back' button to perform the operation on a different input set. However, the back button takes them to the interstitial, not the original form. The desired behavior is to go back to the original form, skipping the interstitial entirely. I'd like this to be default behavior if the user goes to the interstitial page from anywhere but the original form. I thought I could create this by using the @never_cache function decorator in my view for the interstitial, and logic based on request.META['HTTP_REFERER'], however the page doesn't respect these. The browser's back button still trumps this behavior. Any ideas on how to solve this issue?

  • Why doesn't JFreeCharts correctly connect the points in my xy-line graph?

    - by Javajava
    /Each letter A,T,G,C represents a direction for the plot to graph. Specifically, “A” means move right, “T” is move down, “C” is move up, and “G” is move left. When the applet reads A,T,C, it plots the graph correctly. However, when I plot G, the graph is messed up. When I input "ACACACA," the graph is like a rising staircase. When I input "gtgtgt," the graph should look like a staircase, but it looks like a lightning bolt instead/ /This is all one code... i don't know why it's all split up like this:/ import java.applet.Applet; import java.awt.*; import java.awt.event.*; import java.util.Scanner.*; import java.jfree.chart.*; import java.jfree.data.xy.*; import java.jfree.chart.plot.PlotOrientation; public class If_Graph extends Applet implements ActionListener{ Panel panel; TextArea textarea, outputArea; Button move; String thetext; Scanner reader = new Scanner(System.in); String thetext2; int size,p,q; int x,y; public void init(){ setSize(500,500); //set size of applet panel = new Panel(); add(panel); setVisible(true); textarea= new TextArea(10,20); add(textarea); move=new Button("Graph"); move.addActionListener(this); add(move); } public void actionPerformed(ActionEvent e) { XYSeries series = new XYSeries("DNA Walk"); x= 0; y = 0; series.add(x,y); if(e.getSource() == move) { thetext=textarea.getText(); //the text is the DNA bases pasted thetext=thetext.replaceAll(" ",""); //removes spaces thetext2 = ""; for(int i=0; i<thetext.length(); i++) { char a = thetext.charAt(i); switch (a) { case 'A': //moves right x+=1; y+=0; series.add(x,y); break; case 'a': x+=1;y+=0; series.add(x,y); break; case 'C': //moves up x+=0; y+=1; series.add(x,y); break; case 'c': x+=0; y+=1; System.out.println(x + "," + y); series.add(x,y); break; case 'G': //move left x-=1; y+=0; series.add(x,y); System.out.println("G is: "+ x +"," +y); break; case 'g': x-=1; y+=0; System.out.println("g is: " +x + "," + y); series.add(x,y); break; case 'T': //move down x+=0; y-=1; series.add(x,y); System.out.println("T is: "+ x +"," +y); break; case 't': x+=0; y-=1; series.add(x,y); System.out.println("t is: "+ x +"," +y); break; default: // series.add(0,0); break; } } XYDataset xyDataset = new XYSeriesCollection(series); JFreeChart chart = ChartFactory.createXYLineChart ("DNA Random Walk", "", "", xyDataset, PlotOrientation.VERTICAL, true, true, false); ChartFrame frame1=new ChartFrame("DNA Random Walk",chart); frame1.setVisible(true); frame1.setSize(300,300); outputArea.setText(thetext2); } } }

  • Passing Data from Usercontrol to controller

    - by nitinkhanna
    Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

  • How can I make a Jeditable (jQuery) span activate editing on more than one event?

    - by JonathanHayward
    For the jQuery extension Jeditable, one of the parameters that can be specified is which DOM event will turn a div/span/... into a text input/textarea/... I would like to have more than one event serve as a trigger; that is, I would like either a click event or a contextmenu event to turn a span into an in-place edit area. Is there a graceful way to do this without forking Jeditable? --edit-- An example of code specifying the event is below. The parameter is optional, defaulting to a regular click. $(".edit_rightclick").editable("/ajax/save", { cancel: "Cancel", submit: "OK", tooltip: "Right click to edit.", event: "contextmenu", }); Calling twice, once for the regular click event with the event unspecified, and one for the contextmenu event (right-click if there are no switched mouse buttons or anything like that) does not seem to produce the intended effect of an element becoming editable in place on a click from either mouse button.

  • Use 'let' in 'if' expression

    - by demas
    I need a function that works like this: foo :: Integer -> Integer -> [Integer] foo a b = do let result = [] let Coord x y = boo a b if x > 0 let result = result ++ [3] if y > 0 let result = result ++ [5] if x < a let result = result ++ [7] if y < b let result = result ++ [9] result I can not use the guards because the result can have more then one element. But as I see I can not use 'let' in the 'if' expression: all_possible_combinations.hs:41:14: parse error on input `let' How can I check multiple expressions and add new elements in the list? I search not only imperative solution, but the functional one.

  • c# GUI changing a listbox from another class

    - by SlowForce
    I've written a multithreaded server that uses tcplistener and a client handler class that controls input and output. I also have a GUI chat client. The chat client works fine and the console version of the server also works well. I have a start() method in the partial(?) Form class, which I run from a new thread when I click a button, that starts the TCP Listener and loops through and accepts socket requests. For every request a new ClientHandler object is created and the socket is passed to this object before being used in a new handler thread. The ClientHandler is a different class to the form and I'm having real problems writing data to the Listbox in the Form class from within the ClientHandler class. I've tried a few different ways of doing this but none of them work as they involve creating a new form class within the ClientHandler. Any help or advice on what I should be reading to help me would be really appreciated.

  • change/part doesn't work as expected with parse

  • Removing final bash script argument

    - by ctuffli
    I'm trying to write a script that searches a directory for files and greps for a pattern. Something similar to the below except the find expression is much more complicated (excludes particular directories and files). #!/bin/bash if [ -d "${!#}" ] then path=${!#} else path="." fi find $path -print0 | xargs -0 grep "$@" Obviously, the above doesn't work because "$@" still contains the path. I've tried variants of building up an argument list by iterating over all the arguments to exclude path such as args=${@%$path} find $path -print0 | xargs -0 grep "$path" or whitespace="[[:space:]]" args="" for i in "${@%$path}" do # handle the NULL case if [ ! "$i" ] then continue # quote any arguments containing white-space elif [[ $i =~ $whitespace ]] then args="$args \"$i\"" else args="$args $i" fi done find $path -print0 | xargs -0 grep --color "$args" but these fail with quoted input. For example, # ./find.sh -i "some quoted string" grep: quoted: No such file or directory grep: string: No such file or directory Note that if $@ doesn't contain the path, the first script does do what I want.

  • Comobox event SelectedValueChanged

    - by IordanTanev
    Hi, i have simple question may be someone asked it before me but i could not find it.Let say i have datatable that has some data from the database and i want to bind it to a combobox i use standart code like this comboBox1.BeginUpdate( ); comboBox1.ValueMember = "id"; comboBox1.DisplayMember = "name"; comboBox1.DataSource = dt; comboBox1.EndUpdate( ); The problem is during this binding the event SelectedValueChanged is fired.The problem is that rebind combo several times when outher values change and every time i must do sometihn like this comboBox1.SelectedIndexChanged -= new System.EventHandler( this.comboBox1_SelectedValueChanged ); my question is there a smarter way to skip the event when i comes from databinding not from user input.The problem is that i want to do it some how globaly in my control that inherits combobox and not to do it everytime in every from Best Regards, Iordand

  • jQuery sibling selector?

    - by Brett
    Hi, I have a table which I'm trying to do a pricing list, that auto-computes the tax component.. I'm getting the value from price_1, applying a math cal, and saving it to tax_1. I could read the number of the end of the id, but hopefully there is a cleaner way with jQuery. E.g. I would have a lot of fields like.. price_1 price_2 price_3 tax_1 tax_2 tax_3 etc... I can use the following code to call jQuery on change of a price, and get the value of that price. How do I update the tax field next to it? should I use a sibling selector or something?? $('#pricing').delegate("input", "change", function(){ $(this).val() /* the value of the price */; })

  • Java generics question

    - by user247866
    So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = methodCall(); // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void someMethod(List<A> a) However, when I do: C c = new C(); c.someMethod(b); I get an error that some-method is not applicable for the argument List<B>, instead it's expecting to get List<A>. Is there a good way to fix this problem? Many thanks!

  • Good workflow for website design

    I would like some idea about a good workflow for Website Design, with a high degree of "offshoring" (Elance, Odesk etc.). I would to do as much as possible "pre production", with client input, ideas etc. stored in IA diagrams, wireframe mockups etc. in something like a Wiki. Also a like the idea about having different people come up with different design proposals. Wouldlike to have some ideas of costs of different phases and tasks ($, %, hours). With Design I mean roughly the aspects of a site that can be done with client-side tools, especially XHTML and CSS. What other tools should I use than IA diagrams.

  • Serving large generated files using Google App Engine?

    - by John Carter
    Hiya, Presently I have a GAE app that does some offline processing (backs up a user's data), and generates a file that's somewhere in the neighbourhood of 10 - 100 MB. I'm not sure of the best way to serve this file to the user. The two options I'm considering are: Adding some code to the offline processing code that 'spoofs' it as a form upload to the blob store, and going thru the normal blobstore process to serve the file. Having the offline processing code store the file somewhere off of GAE, and serving it from there. Is there a much better approach I'm overlooking? I'm guessing this is functionality that isn't well suited to GAE. I had thought of storing in the datastore as db.Text or Dd.Blob but there I encounter the 1 MB limit. Any input would be appreciated,
