  • Is this a valid C statement ?

    - by Philando Gullible
    Lets say I write char c[99] = {'Stack Overflow'}; in C or C++ it does compiles fine but does this valid? By valid I meant not invoking any kind of undefined or unspecified behavior. Again if I write char c[99] = 'Stack Overflow'; gcc complains about multicharacter constant which is obvious but in the above when I am enclosing within curly brackets compiler is happy! why is it so ? I also notice that puts(c); after the first statement will output 'w' precisely the last character of a general string in-place of Stack Overflow. why so ? Could somebody explain this behavior may be separately.

  • Adding C++ DLL's to a C# project

    - by WebDevHobo
    I'm trying to use the lame_enc.dll file from LAME in a C# project, but adding the thing seems impossible. I keep getting an error that says that a reference could not be added and to please check if the is accessible, a valid assembly or COM component. I have no C++ experience, though I would like to use the functionality. Right now I'm using Process from the .NET framework to call lame.exe and do stuff, but I'd like to know if there's another way.

    - by E.E.33
    I want to change my layout based on whether or not the current user is an admin. So I made a simple method to check if current user is admin, I then call that method in application controller.

Thanks

  • How to $.extend 2 objects by adding numerical values together from keys with the same name?

    - by muudless
    I currently have 2 obj and using the jquery extend function, however it's overriding value from keys with the same name. How can I add the values together instead? obj1 = {"orange":2,"apple":1, "grape":1} obj2 = {"orange":5,"apple":1, "banana":1} mergedObj = $.extend({}, obj1, obj2); var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) { var arr = []; $.each(obj, function(key, val) { var next = key + ": "; next += $.isPlainObject(val) ? printObj(val) : val; arr.push( next ); }); return "{ " + arr.join(", ") + " }"; }; console.log('all together: '+printObj(mergedObj) ); And I get obj1 = {"orange":5,"apple":1, "grape":1, "banana":1} What I need is obj1 = {"orange":7,"apple":2, "grape":1, "banana":1}

    - by ravisoni

  • What is the first ORM framework?

    - by user1014315
    I'm doing a presentation about history of software engineering and stuck at this question due to the lack of available information. According to my quick research, TopLink is the first ORM framework ever created (in 1990s, certainly before 1996). If anyone else has a different opinion, please let me know. (Please also provide a link to the reference sources) Ref: http://en.wikipedia.org/wiki/List_of_object-relational_mapping_software http://en.wikipedia.org/wiki/TopLink

  • why does the data property in an jquery ajax call override my return false?

    - by user315709
    hi, i have the following block of code: $("#contact_container form, #contact_details form").live( "submit", function(event) { $.ajax({ type: this.method, url: this.action, data: this.serialize(), success: function(data) { data = $(data).find("#content"); $("#contact_details").html(data); }, }); return false; } ; when i leave out the data: this.serialize(), it behaves properly and displays the response within the #contact_details div. however, when i leave it in, it submits the form, causing the page to navigate away. why does the presence of the data attribute negates the return false? (probably due to a bug that i can't spot...) also, is the syntax to my find statement correct? it comes back as "undefined" even though i use a debugger to check the ajax response and that id does exists. thanks, steve

  • Path Inclusion/Global variable not working?

    - by Dan LaManna
    Simply put, my config file includes my database class, and the config file has in it: global $db; $db = new database(DB_HOST, DB_NAME, DB_USER, DB_PASS); That file is root/config.php Moving on to root/functions/func.newpage.php doesn't have any includes/requires, and uses $db-classfunction since the file I'm working with: root/newpage.php - requires the config file, as well as func.newpage.php. However I still come up with: Undefined variable db. Anything you guys are seeing I'm not? Thanks! Let me know if more details are needed.

  • PHP - Get values from Array

    - by danit
    I am trying to get a record from a database using an sql lookup (sql1). This then returns as an array which is fine, but I need to use part of the array for my next stage. $opt=get_records_sql($sql1); //Diags for SQL content print_object($opt); $n = count($opt); if (empty($opt)) { echo 'No options selected'; } else { $optno = $opt["subjectid"]; // Diags of $optno echo '<br>$optno = '.$optno; As you can see, I tried to use this: $opt["subjectid"] as subjectid is the fieldname that I am trying to access and I was under the impression that this was correct for accessing an array, but I get the following error: Notice: Undefined index: subjectid Array contents: Array ( [1] => stdClass Object ( [uname] => JHollands06 [tutor] => M LSt [subjectid] => 1 [year] => 2010 [optid] => 1 ) )

  • Namespace and class conflict(?)

    - by dan gibson
    This is a bad title for the question, but I'm not quite sure of a better one. I have a namespace called Globals with a class X in it. I also have a class called Globals. When I try to access Globals.X.StaticMember it tries to access the class Globals.X and complains that X doesn't exist. How do I reference the namespace Globals - ie ::Globals.X.StaticMember (:: doesn't compile).

    - by 730
    I instantiate an object, with an argument which is a button. When the button of an instance is clicked, it should run a function, but it doesn't. In the full version of the code, Chrome gives this message in the console: "Uncaught TypeError: Cannot read property 'onclick' of undefined" HTML: <textarea id='txt' readonly rows='5' cols='40'></textarea> <button id='btn' type='button'>click</button> JS: var btn = document.getElementById('btn'); var txt = document.getElementById('txt'); var foo = new Foo(btn); function Foo(btn) { this.button = btn; } Foo.prototype.buy = function() { txt.value = 'Foo Bar'; }; Foo.button.onclick = function() { foo.buy(); }; Fiddle
