  • How i can fix the increasing order summation code?

    - by user2971559
    I want from the java to reads all numbers from the user as long as the number entered by user is bigger than the previous number. But i could write it for only positive numbers. How i can fix code below if all numbers included. If it is possible please write the solution for beginners because its my first year in computer science in college and I haven't learn a lot yet. import acm.program.*; public class IncreasingOrder extends ConsoleProgram { public void run() { int previousNumber = 0; int total = 0; int count = 0; while(true) { int n = readInt("Enter > "); if (n <= previousNumber) break; total += n; count++; previousNumber = n; } println("You have entered " + count + " numbers in increasing order."); println("Sum of these " + count + " numbers is " + total + "."); } }

  • Symfony 1.4 Form Value change after getValues()

    - by bertzzie
    Hi, I've got some problem with symfony form value (i guess it's the clean value, but not so clear yet). Here's the problem : I got a sfFormDateJQueryUI widget setup like this in my form : $this->setWidgets(array( 'needDate' => new sfWidgetFormDateJQueryUI(), )); $this->setValidators(array( 'needDate' => new sfValidatorDate(array( 'required' => true, 'date_format' => '/^[0-9]{2}\/[0-9]{2}\/[0-9]{4}$/', 'date_output' => 'd/m/Y' )), )); Then when i submit, say 26/06/2010, it turns out right in the HTTP Header (viewed via Firebug) and $request (i just print it). But after i get the value via $formVal = $form->getValues(); the date value in $formVal["needDate"] become today's date (03/06/2010). I really don't understand, and after checking in the API documentation it says that the getValues will return the 'cleaned' value. Is that because of it ? I don't understand what's 'clean'. Thanks before..

  • Java servlet's request parameter's name set to entire json object

    - by Geren White
    I'm sending a json object through ajax to a java servlet. The json object is key-value type with three keys that point to arrays and a key that points to a single string. I build it in javascript like this: var jsonObject = {"arrayOne": arrayOne, "arrayTwo": arrayTwo, "arrayThree": arrThree, "string": stringVar}; I then send it to a java servlet using ajax as follows: httpRequest.open('POST', url, true); httpRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); httpRequest.setRequestHeader("Connection", "close"); var jsonString = jsonObject.toJSONString(); httpRequest.send(jsonString); This will send the string to my servlet, but It isn't showing as I expect it to. The whole json string gets set to the name of one of my request's parameters. So in my servlet if I do request.getParameterNames(); It will return an enumeration with one of the table entries' key's to be the entire object contents. I may be mistaken, but my thought was that it should set each key to a different parameter name. So I should have 4 parameters, arrayOne, arrayTwo, arrayThree, and string. Am I doing something wrong or is my thinking off here? Any help is appreciated. Thanks

  • php memory how much is too much

    - by Rob
    I'm currently re-writing my site using my own framework (it's very simple and does exactly what I need, i've no need for something like Zend or Cake PHP). I've done alot of work in making sure everything is cached properly, caching pages in files so avoid sql queries and generally limiting the number of sql queries. Overall it looks like it's very speedy. The average time taken for the front page (taken over 100 times) is 0.046152 microseconds. But one thing i'm not sure about is whether i've done enough to reduce php memory usage. The only time i've ever encountered problems with it is when uploading large files. Using memory_get_peak_usage(TRUE), which I THINK returns the highest amount of memory used whilst the script has been running, the average (taken over 100 times) is 1572864 bytes. Is that good? I realise you don't know what it is i'm doing (it's rather simple, get the 10 latest articles, the comment count for each, get the user controls, popular tags in the sidebar etc). But would you be at all worried with a script using that sort of memory getting hit 50,000 times a day? Or once every second at peak times? I realise that this is a very open ended question. Hopefully you can understand that it's a bit of a stab in the dark and i'm really just looking for some re-assurance that it's not going to die horribly come re-launch day.

  • Margin for select option in IE and chrome is not working

    - by Sardor
    I am setting a css class to some select options in JS. This class includes margin style. It is working in the FF but not in IE and chrome. window.onload = function() { replace('edit-field-region-tid'); replace('edit-tid'); } function replace(id) { var i = 0; var s = document.getElementById(id); for (i; i < s.options.length; i++) { if (find(s.options[i].text, id, i)) { s.options[i].setAttribute("class", "sub_options"); } } } function find(str, id, option_id) { var i; var s = document.getElementById(id); for (i = 0; i < str.length; i++) { if (str.charAt(i) == '-') { s.options[option_id].text = str.cutAt(0, ""); return true; } } return false; } String.prototype.cutAt = function(index, char) { return this.substr(index+1, this.length); } And CSS: .sub_options{ margin-left:20px; text-indent:-2px; } Any ideas thanks!

  • SDL (And Others) Virtual Key Input

    - by David C
    Today I set up the input in my application for all the different keys. This works fine except for virtual keys, for example, caret or ampersand. Keys that normally need shift to be got at. Using SDL these virtual keys don't work. As in they do not register an event. if (event.type == SDL_KEYDOWN) { switch (event.key.keysym.sym) { case SDLK_CARET: Keys[KeyCodes::Caret] = KeyState::Down; break; case SDLK_UP: Keys[KeyCodes::Up] = KeyState::Down; break; default: break; } I am absolutely sure my system works with physical keys like Up. The program queries a keystate like so: if (Keys[KeyCode] == KeyState::Down) { lua_pushboolean(L, true); } else { lua_pushboolean(L, false); } KeyCode is passed in as an argument. So why are virtual keys, or keys that need shift to get at not working using SDL's KeyDown event type? Is more code needed to get to them? Or am I being stupid?

  • PHP & MySQL storing multiple values in a database.

    - by R.I.P.coalMINERS
    I'm basically a front end designer and new to PHP and MySQL but I want a user to be able to store multiple names and there meanings in a MySQL database table named names using PHP I will dynamically create form fields with JQuery every time a user clicks on a link so a user can enter 1 to 1,000,000 different names and there meanings which will be stored in a table called names. All I want to know is how can I store multiple names and there meanings in a database and then display them back to the user for them to edit or delete using PHP MySQL? I created the MySQL table already. CREATE TABLE names ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, userID INT NOT NULL, name VARCHAR(255) NOT NULL, meaning VARCHAR(255) NOT NULL, PRIMARY KEY (id) ); Here is the HTML. <form method="post" action="index.php"> <ul> <li><label for="name">Name: </label><input type="text" name="name" id="name" /></li> <li><label for="meaning">Meaning: </label><input type="text" name="meaning" id="meaning" /></li> <li><input type="submit" name="submit" value="Save" /> <input type="hidden" name="submit" value="true" /></li> </ul> </form>

  • How can I automate new system provisioning with scripts under Mac OS X 10.6?

    - by deeviate
    I've been working on this for days but simply cannot find the correct references to make it work. The idea is to have a script that will baseline newly purchased Macs that comes into the company with basic stuffs like set autologin to off, create a new admin user (for remote admins to access for support, set password to unlock screensaver and etc) . Sample list for baseline that admins have to do on each new machine: Click the Login Options button Set Automatic Login: OFF Check: Show the Restart, Sleep, and Shutdown buttons Uncheck: Show input menu in login window Uncheck: Show password hints Uncheck: Use voice over in the login window Check: Show fast user switching menu as Short Name (note: this is only part of a long list to do on each machine) I've managed to find some references to make some parts work. Like autologin can be unset with: defaults write /Library/Preferences/.GlobalPreferences com.apple.userspref.DisableAutoLogin -bool TRUE and I've kinda found ways to muscle in a new user creation (including prompts) with AppleScript and shell commands. But generally its tough finding ways to do somewhat simple things like turn on password to get out of screensaver or to allow fast user switching. References are either too limited or just no where to be seen (e.g. I can unset autologin via cli but the very next setting on the system preference "show restart, sleep and shutdown buttons" is somewhere else and I can't find any command line to make it set) Does anyone have any ideas on a list, document, reference or anything of where each setting on the system resides so that I can be pointed to make it work? or maybe sample scripts for the above example... My thanks for reading thus far—a huge thank you for whoever that has any info on the above.

  • GetLocalValueEnumerator() Not Returning All Properties

    - by a_hardin
    I am trying to perform validation in my WPF application using the solution in Detecting WPF Validation Errors. public static bool IsValid(DependencyObject parent) { // Validate all the bindings on the parent bool valid = true; LocalValueEnumerator localValues = parent.GetLocalValueEnumerator(); while (localValues.MoveNext()) { LocalValueEntry entry = localValues.Current; if (BindingOperations.IsDataBound(parent, entry.Property)) { Binding binding = BindingOperations.GetBinding(parent, entry.Property); foreach (ValidationRule rule in binding.ValidationRules) { ValidationResult result = rule.Validate(parent.GetValue(entry.Property), null); if (!result.IsValid) { BindingExpression expression = BindingOperations.GetBindingExpression(parent, entry.Property); System.Windows.Controls.Validation.MarkInvalid(expression, new ValidationError(rule, expression, result.ErrorContent, null)); valid = false; } } } } // Validate all the bindings on the children for (int i = 0; i != VisualTreeHelper.GetChildrenCount(parent); ++i) { DependencyObject child = VisualTreeHelper.GetChild(parent, i); if (!IsValid(child)) { valid = false; } } return valid; } The problem I am running into is that when I step through the code for a TextBox, I'm not getting the Text property. The only properties I get are "PageHeight", "Instance", and "UndoManagerInstance". Therefore, I can not Validate the rules for the binding on the TextBox. Does anyone have any idea why I wouldn't be getting the correct properties? Is there another way to force validaton on controls in WPF? I haven't been able to find anyone else who has had this problem. Update: The TextBoxes I am trying to validate are within a DataTemplate. I found that if I copy one of the TextBoxes and place it directly in the Window, I am able to get the data. Using Woodstock, I saw that the data source for the TextBoxes in the template is "ParentTemplate", but it's "Local" for the TextBox outside of the template. So, the question now is, how can I get the DependencyProperties for controls inside a DataTemplate?

  • Can anyone help with this (Javascript arrays)?

    Hi I am new to Netui and Javascript so go easy on me please. I have a form that is populated with container.item data retuned from a database. I am adding a checkbox beside each repeater item returned and I want to add the container item data to an array when one of the checkboxes is checked for future processing. The old code used Anchor tag to capture the data but that does not work for me. <!--netui:parameter name="lineupNo" value="{container.item.lineupIdent.lineupNo}" /> here is my checkbox that is a repeater. <netui:checkBox dataSource="{pageFlow.checkIsSelected}" onClick="checkBoxClicked()" tagId="pceChecked"/> this is my Javascript function so far but I want to a way to store the container.item.lineupIdent.lineupNo in the array. function checkBoxClicked() { var checkedPce = []; var elem = document.getElementById("PceList").elements; for (var i = 0; i < elem.length; i ++) { if (elem[i].name == netui_names.pceChecked) { if (elem[i].checked == true) { //do some code. } } } } I hope this is enough info for someone to help me. I have searched the web but could not find any examples. Thanks.

  • Why does false invalidate validates_presence_of?

    - by DJTripleThreat
    Ok steps to reproduce this: prompt> rails test_app prompt> cd test_app prompt> script/generate model event_service published:boolean then go into the migration and add not null and default published to false: class CreateEventServices < ActiveRecord::Migration def self.up create_table :event_services do |t| t.boolean :published, :null => false, :default => false t.timestamps end end def self.down drop_table :event_services end end now migrate your changes and run your tests: prompt>rake db:migrate prompt>rake You should get no errors at this time. Now edit the model so that you validate_presence_of published: class EventService < ActiveRecord::Base validates_presence_of :published end Now edit the unit test event_service_test.rb: require 'test_helper' class EventServiceTest < ActiveSupport::TestCase test "the truth" do e = EventServer.new e.published = false assert e.valid? end end and run rake: prompt>rake You will get an error in the test. Now set e.published to true and rerun the test. IT WORKS! I think this probably has something to do with the field being boolean but I can't figure it out. Is this a bug in rails? or am I doing something wrong?

  • XNA, C# - Check if a Vector2 path crosses another Vector2 path.

    - by Nick
    Hello all, I have an XNA question for those with more experience in these matters than myself (maths). Background: I have a game that implements a boundary class, this simply hosts 2 Vector2 objects, a start and an end point. The current implementation crudely handles collision detection by assuming boundaries are always vertical or horizontal, i.e. if start.x and end.x are the same check I am not trying to pass x etc. Ideally what I would like to implement is a method that accepts two Vector2 parameters. The first being a current location, the second being a requested location (where I would like to move it to assuming no objections). The method would also accept a boundary object. What the method should then do is tell me if I am going to cross the boundry in this move. this could be a bool or ideally something representing how far I can actually move. This empty method might explain better than I can in words. /// <summary> /// Checks the move. /// </summary> /// <param name="current">The current.</param> /// <param name="requested">The requested.</param> /// <param name="boundry">The boundry.</param> /// <returns></returns> public bool CheckMove(Vector2 current, Vector2 requested, Boundry boundry) { //return a bool that indicated if the suggested move will cross the boundry. return true; }

  • What is the point of having a key_t if what will be the key to access shared memory is the return value of shmget()?

    - by devoured elysium
    When using shared memory, why should we care about creating a key key_t ftok(const char *path, int id); in the following bit of code? key_t key; int shmid; key = ftok("/home/beej/somefile3", 'R'); shmid = shmget(key, 1024, 0644 | IPC_CREAT); From what I've come to understand, what is needed to access a given shared memory is the shmid, not the key. Or am I wrong? If what we need is the shmid, what is the point in not just creating a random key every time? Edit @link text one can read: What about this key nonsense? How do we create one? Well, since the type key_t is actually just a long, you can use any number you want. But what if you hard-code the number and some other unrelated program hardcodes the same number but wants another queue? The solution is to use the ftok() function which generates a key from two arguments. Reading this, it gives me the impression that what one needs to attach to a shared-memory block is the key. But this isn't true, is it? Thanks

[viewController.view release]; //release gamestate } viewController.view = [[scene alloc] initWithFrame:CGRectMake(0, 0, IPHONE_WIDTH, IPHONE_HEIGHT) andManager:self]; //now set our view as visible [window addSubview:viewController.view]; [window makeKeyAndVisible]; if(animateTransition){ [UIView commitAnimations]; } }

  • Error emailing outgoing sms

    - by BirthOfTragedy
    Is there anyway to listen for an outbound sms without having to import javax.wireless.messaging? I'm trying to write an app that listens for an sms sent from the device then emails the message of the sms, but I get the error: reference to Message is ambiguous, both class javax.wireless.messaging.Message in javax.wireless.messaging and class net.rim.blackberry.api.mail.Message in net.rim.blackberry.api.mail match I need to import net.rim.blackberry.api.mail.Message in order to sent an email. Is there a way to get around this as it seems that the two packages are clashing. My code: public void notifyIncomingMessage(MessageConnection messageconnection) {} public void notifyOutgoingMessage(javax.wireless.messaging.Message message) { try { String address = message.getAddress(); String msg = null; if ( message instanceof TextMessage ) { TextMessage tm = (TextMessage)message; msg = tm.getPayloadText(); } else if (message instanceof BinaryMessage) { StringBuffer buf = new StringBuffer(); byte[] data = ((BinaryMessage) message).getPayloadData(); msg = new String(data, "UTF-8"); Store store = Session.getDefaultInstance().getStore(); Folder[] folders = store.list(Folder.SENT); Folder sentfolder = folders[0]; Message in = new Message(sentfolder); Address recipients[] = new Address[1]; recipients[0]= new Address("[email protected]", "user"); in.addRecipients(Message.RecipientType.TO, recipients); in.setSubject("Outgoing sms"); in.setContent("You have just sent an sms to: " + address + "\n" + "Message: " + msg); in.setPriority(Message.Priority.HIGH); Transport.send(in); in.setFlag(Message.Flag.OPENED, true); Folder folder = in.getFolder(); folder.deleteMessage(in); } } catch (IOException me) { System.out.println(me); } } }

  • assigning values to variables within foreach loop

    - by Patrick
    Im working on a script to tear into a csv file and ive got the rows separated, but im not sure how to assign variables to the fields within the row, so that i can perform functions with them. my code: <? ini_set('auto_detect_line_endings', true); $csvraw = file_get_contents("file.csv"); $csv = explode("\n", $csvraw); $i=0; foreach($csv AS $key=>$value){ $rowsplit = explode(",", $value); // This is where i get my headers if($i == 0){ $col0 = $rowsplit[0]; $col1 = $rowsplit[1]; $col2 = $rowsplit[2]; $col3 = $rowsplit[3]; $col4 = $rowsplit[4]; $col5 = $rowsplit[5]; $col6 = $rowsplit[6]; $col7 = $rowsplit[7]; } $i++; //This is where i loop through each row's fields foreach($rowsplit AS $key2=>$value2){ if(empty($value2)){ echo ""; }else{ echo "$value2 <br>"; } // This is where i need to assign $variable0 through $variable7 so i can perform a function with the field values. } echo "<br><br><br>"; } ?>

  • How to correctly pass a float from C# to C++ (dll)

    - by RavelT
    I'm getting huge differences when I pass a float from C# to C++. I'm passing a dynamic float wich changes over time. With a debuger I get this: c++ lonVel -0.036019072 float c# lonVel -0.029392920 float I did set my MSVC++2010 floating point model to /fp:fast wich should be the standard in .NET if I'm not mistaken, but this didnt help. Now I cant give out the code but I can show a fraction of it. From C# side it looks like this: namespace Example { public class Wheel { public bool loging = true; #region Members public IntPtr nativeWheelObject; #endregion Members public Wheel() { this.nativeWheelObject = Sim.Dll_Wheel_Add(); return; } #region Wrapper methods public void SetVelocity(float lonRoadVelocity,float latRoadVelocity){Sim.Dll_Wheel_SetVelocity(this.nativeWheelObject,lonRoadVelocity,latRoadVelocity);} #endregion Wrapper methods } internal class Sim { #region PInvokes [DllImport(pluginName, CallingConvention=CallingConvention.Cdecl)] public static extern void Dll_Wheel_SetVelocity(IntPtr wheel,float lonRoadVelocity,float latRoadVelocity); #endregion PInvokes } } And in C++ side @ exportFunctions.cpp: EXPORT_API void Dll_Wheel_SetVelocity(CarWheel* wheel,float lonRoadVelocity,float latRoadVelocity){ wheel->SetVelocity(lonRoadVelocity,latRoadVelocity);} So any sugestions on what I should do in order to get 1:1 results or atleast 99% correct results.
