  • Variable not accessible within and if statment

    - by Chris
    I have a variable which holds a score for a game. My variable is accessible and correct outside of an if statement but not inside as shown below cout << score << endl; //works if(!justFinished){ cout << score << endl; // doesn't work prints a large negative number endTime = time(NULL); ifstream highscoreFile; highscoreFile.open("highscores.txt"); if(highscoreFile.good()){ highscoreFile.close(); }else{ std::ofstream outfile ("highscores.txt"); cout << score << endl; outfile << score << std::endl; outfile.close(); } justFinished = true; } cout << score << endl;//works

  • Long variable names

    - by RaouL
    Lets say i have a variable that contains the number of search engine names in a file, what would you name it? number_of_seach_engine_names search_engine_name_count num_search_engines engines engine_names other name? The first name describes what the variable contains precisely, but isn't it too long?, any advice for choosing variable names? especially how to shorten a name that is too long or what kind of abbreviations to use?

  • Flex Application for PlayBook Text Input Variable

    - by user568128
    I know this is probably a very simple question, but can someone please walk me through how to take what a user inputs into a s:TextInput and use that as a variable in a JSON data request? Basically, I want to have a user enter a search term, like "math" and then have that placed into a variable so I can use it in a JSON request. Something like public var q:String, except that my search box (and hence user input) is on another "view" of the application. I've just started with Flex Mobile applications and I might be way out of my league. Does anyone know how to do this?

  • C++ - 3 possible values in Variable?

    - by noryb009
    I need to store a 30 letter combination, but each letter can only be "0", "1" or "2". When I use sizeof(myString), it returns 32. I want to use this 30 letter combination to access a row of an array, so I'm wondering if it is possible to use a 3 value bool of some sort to store 1 of 3 values in.

  • Variable within variable possible?

    - by JM4
    I am trying to create a loop statement for some of my code and am wondering how I can put a variable within another variable. For example: <?php $j=1; while ($j <= 9): { $f$jfname = $_SESSION['F$jFirstName']; $f$jmi = $_SESSION['F$jMI']; $f$jlname = $_SESSION['F$jLastName']; } $j++; endwhile; ?> Where the goal is to have the j variable increase during the loop and change the values as: $f1fname $f2fname $f3fname and so on. Any ideas?

  • Changing the value of a variable

    - by neirpycc
    I'm trying to build a simple scoring app but I'm running into a problem trying to keep it so I don't have to repeat a bunch of code to deal with each 'base' individually. The basic idea is that when I click a button the script will; 1) grab the ID of said button 2) split the ID into two parts - (a) the bases name and (b) the button type (plus/minus) 3) if it's plus - add to the bases score, if it's minus - subtract from the bases score 4) update the assigned div with the new value The part I'm stuck at is adding and subtracting. I can't seem to get this to work. Here is the code: $('.base button').click(function() { var b1Score = 0; var b2Score = 0; var b3Score = 0; var b4Score = 0; var b5Score = 0; var clickedButton = $(this).attr('id'); var buttonInfo = clickedButton.split('-'); var baseClicked = buttonInfo[0]; var baseDirection = buttonInfo[1]; var baseDiv = ('#' + baseClicked); console.log('You clicked ' + clickedButton + '.'); if (baseDirection.indexOf('plus') >= 0) { console.log('Increasing ' + baseClicked + '!'); ++; $(baseDiv).val(); } else { console.log('Decreasing ' + baseClicked + '!'); --; $(baseDiv).val(); } }); ++; and --; are placeholders for where the adding and subtracting needs to happen. I just can't figure out how to get it to add or subtract from the correct value. Any help is appreciated. Thanks.

  • Dynamic-linked DLL needs to share a global variable with its caller.

    - by Fabian Wickborn
    I have a static library libStatic that defines a global variable like this Header file libStatic/globals.h: extern int globvar; Code file libStatic/globals.cpp: int globvar = 42; The DLL libDynamic and the executable runner are using this global variable. Furtheron, libDynamic is linked at run-time into runner (via LoadLibrary(), GetProcAddress(), and the works...) I understand this will lead to globvar being created twice, once in the heap of runner and once in the heap of libDynamic, which is of course very undesirable. Is there a good away around this? How can I ensure that libDynamic and runner are using the same globvar?

  • Should I convert data arrays to objects in PHP in a CouchDB/Ajax app?

    - by karlthorwald
    I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips?

  • Java environmental variable woes, maven also

    - by Blankman
    So I re-installed java in a directory that doesn't have any spaces in it, as I was having issues with it before. Java JDK is installed in: E:\downloads\java\jdk I created a User variable: JAVA_HOME E:\downloads\java\jdk And my Path looks like: %JAVA_HOME%\bin;%M2%; Now opening a NEW cmd prompt: c:\java 'java' is not recognized... but echoing works: c:\echo %JAVA_HOME% E:\downloads\java\jdk and so does this: c:\%JAVA_HOME%\bin\java -version java version "1.6.0_17" I am trying to get this to work, so I can then get maven to work as maven is having the same type of issues (I created M2_HOME and M2 and none work). What exactly am I doing wrong? I am having the exact same issue on my laptop also, both are running windows 7. I must be missing something!

  • Ant loadfile override property

    - by lucks
    Hi, I'm trying to use the Ant task <loadfile> in a loop to parse the contents of a file. I have something like <loadfile srcFile="@{some.input}" property="my.property"> Since Ant properties are immutable, this doesn't work for me. I need 'my.property' to update on every iteration. Is there a way to achieve this? I know Ant-contrib has a <var> task but I'm not sure how to use <loadfile> with it. Any recommendations? Thanks.

  • Variable wont echo

    - by jonnnnnnnnnie
    I have the following code, where the var $username doesn't echo, when you type in a value. //TODO: SET AUTH TOKEN as random hash, save in session $auth_token = rand(); if (isset($_POST['action']) && $_POST['action'] == 'Login') { $errors = array(); //USED TO BUILD UP ARRAY OF ERRORS WHICH ARE THEN ECHOED $username = $_POST['username']; if ($username = '') { $errors['username'] = 'Username is required'; } echo $username; // var_dump($username) returns string 0 } require_once 'login_form.html.php'; ?> login_form is this: <form method="POST" action=""> <input type="hidden" name="auth_token" value="<?php echo $auth_token ?>"> Username: <input type="text" name="username"> Password: <input type="password" name="password1"> <input type="submit" name="action" value="Login"> </form> The auth token part isn't important, it just when I type in a value in username textbox and press the login button, the username wont echo, var_dump returns string (0) and print_r is just blank.

  • Variable text in links with knockout

    - by Gepser
    I'm generating a list of links and they have not the same text but I don't know how to put a text with knockout. This is what I have: <a data-bind="attr: { href: 'Controller/Method/' + Id, 'Title': CurrentTask }"> <!-- I need the name of the CurrentTask here--> CurrentTask </a> So, the text I want to show appears only in the "alt" property but not in the text of the link. It works but I need that the name of the CurrentTask be the link and now it's just showing me everything like this: <a href...>CurrentTask</a> <a href...>CurrentTask</a> <a href...>CurrentTask</a> <a href...>CurrentTask</a> and I need this <a href...>I get this data from de controller</a> <a href...>Sometext</a> <a href...>OtherText</a> <a href...>Anything</a>

  • Trying to instantiate a class member in C++ with a variable name

    - by MarcZero
    Hello. I am writing a program for class that is asking us to create a class of "book". We are then supposed to create new instantiations of that class upon demand from the user. I am new to C++ so I am attempting to code this out but am running into a problem. The main problem is how do I instantiate a class with a variable if I don't know how many I will have to do ahead of time. The user could ask to add 1 book or 1000. I am looking at this basic code: This is the simple code I started with. I wanted to have an index int keep a number and have the book class I create be called by that int (0, 1, 2, etc...) So I attempted to convert the incoming index int into a string, but I'm kind of stuck from here. void addBook(int index){ string bookName; std::stringstream ss; ss << index; book bookName; cout << "Enter the Books Title: "; cin >> bookName.title; } But obviously this doesn't work as "bookName" is a string to the computer and not the class member I tried to create. All of the tutorials I have seen online and in my text show the classes being instantiated with names in the code, but I just don't know how to make it variable so I can create any amount of "books" that the user might want. Any insight on this would be appreciated. Thank you for your time.

  • session_set_cookie_params on multi-domain sites

    - by nillls
    Hi! I'm currently developing for an application (www.domain.se, .eu) where we're experiencing problems with sessions not propagating across domains. Internet Explorer is the root cause of this, as it will differentiate sessions depending on whether we're typing in "domain.se" or "www.domain.se". Due to some unfortunate redirecting, we're not able to keep the user on the same address the user typed in, instead we're always redirecting to www.domain.se on login. Needless to say, IE users can not login when typing "domain.se". To make this error go away, we implemented a function to try and set the session to be valid across all possible domains by doing the following: if($_SERVER['HTTP_HOST'] == "domain.se") { session_set_cookie_params(3600, '/', '.domain.se', true); } There are basically a few if:s that we go through depending on what address the user typed in, but the third argument stays the same. This, however, results in no-one being able to log in, regardless of domain. I've tried reading up on how session_set_cookie_params() works but to no avail. Any help is greatly appreciated!

  • How do I create if statements in php to perform a specific action depending on what form has string in it

    - by user1637284
    Im trying to create a grid on my page in each cell there will be a simple one line form. If a person enters data into lets say FieldA I would like the php to perform actionA but if the data was entered in FieldF I would like actionF performed. Is this possible without having to create a php for each cell and upload all those php files? Or is there a way to perform the GET method in each form to append the data to the end of the action url without the field name showing (ie sample.com/somestuff/fieldA instead of sample.com/somestuff/fieldname=fieldA) thus not needing php at all?
