    - by Keith Donegan
    Hey Guys, I have the following html: HTML markup <ul id="test"> <li><a href="http://www.yahoo.com">yahoo</a></li> <li><a href="http://www.google.com">Google</a></li> </ul> And some JS code: JQuery/JavaScript Code $('ul#test').each(function() { var select=$(document.createElement('select')).insertBefore($(this).hide()); $('>li a', this).each(function() { option=$(document.createElement('option')).appendTo(select).val(this.href).html($(this).html()); }); }); This code produces a select dropdown menu, exactly what I want, but my question is how do I go to the url on select?

  • C++: namespace conflicht between extern "C" and class member

    - by plaisthos
    Hi, I stumbled upon a rather exotic c++ namespace problem: condensed example: extern "C" { void solve(lprec * lp); } class A { public: lprec * lp; void solve(int foo); } void A::solve(int foo) { solve(lp); } I want to call the c funcition solve in my C++ member function A::solve. The compiler is not happy with my intents: error C2664: 'lp_solve_ilp::solve' : cannot convert parameter 1 from 'lprec *' to 'int' Is there something I can prefix the solve function? C::solve does not work

  • overflow technique in stack

    - by metashockwave
    int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

  • Is vbscripting that difficult?

    - by eric young
    I need to write some vbscripts in my new project. I was told by other people that vbscripting is easy, but seems to me, it is not. For example, in the following example (provided by microsoft), these functions: CreateObject, CreateShortcut, as well as these property names: TargetPath, WindowStyle, Hotkey, etc, are used, but I just cannot find the corresponding API documentation about how to use them. In other words, how do you know you need to call these functions in your vbscripts? Visual Studio 2008/2010 do not have templates for vbscript either. Could anybody tell me what I am missing, and what the best way is to do vbscripting? set WshShell = WScript.CreateObject("WScript.Shell") strDesktop = WshShell.SpecialFolders("Desktop") set oShellLink = WshShell.CreateShortcut(strDesktop _ & "\MyExcel.lnk") oShellLink.TargetPath = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE" oShellLink.WindowStyle = 1 oShellLink.Hotkey = "CTRL+SHIFT+F" oShellLink.IconLocation = _ "C:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE, 0" oShellLink.Description = "My Excel Shortcut" oShellLink.WorkingDirectory = strDesktop oShellLink.Save

  • Virtual String Tree - Display subnode when parent node is hidden

    - by daemon_x
    Is there a way to show subnode if the parent node is hidden in the Virtual String Tree ? I have some tasks in the tree structure and I wish to display only tasks which belongs to the current user as the list, but from all levels. What I've done is the function to display a list, which hides tree buttons, tree lines, sets the fixed indent and enable toShowHiddenNodes option. Then in this function I iterate through the whole tree (all levels) and hide nodes which doesn't belong to the current user IsVisible[Node] := False and show those which belongs him IsVisible[Node] := True, but the subnodes which should be displayed are invisible when their parent is hidden. VT.TreeOptions.PaintOptions - toShowButtons - toShowTreeLines + toFixedIndent + toShowHiddenNodes

  • XSLT compile error when using XslCompiledTransform.Load indirectly called from an application.

    - by infant programmer
    I have a component written in C#. Among other things it performs XSL transform on XML data it collects. When I test this feature using another C# project that uses the component it works just fine. However when I export the component as a COM component and try to use this feature from an application it fails on the XslCompiledTransform.Load command with an XSLT compile error. Here is the C# code: (click_me) And the error I am getting is copied in a file. Please find it here: (click_me) The XSLT file along with the number of templates also consists of "C# script" meant for some advanced calculations, which XSLT isn't capable of.

  • PHP Sessions Error

    - by Andrei Korchagin
    I'm new to PHP sessions and I've come across the following error: Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at somefile:someline). As well as this one: Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent by (output started at somefile:someline). The session_start(); is the very first thing in all of my code. I'm not sure what the problem is. It gave me line numbers but all I do on those lines is start the session. Also - I have a portion of code whose POST action is another PHP page. How can I set a $_SESSION variable pertaining to this page within that action page?

  • Ajax, not sending querystring data

    - by Tom Gullen
    var http = false; // Creates xmlhttp object if (navigator.appName == "Microsoft Internet Explorer") { http = new ActiveXObject("Microsoft.XMLHTTP"); } else { http = new XMLHttpRequest(); } http.onreadystatechange = function() { if (http.readyState == 4) { alert(http.responseText); } } // Functions to calculate optimum layout etc. function compute() { var statusSpan = document.getElementById("cwStatus"); document.getElementById("fader").style.display = ""; document.getElementById("computingWait").style.display = ""; statusSpan.innerHTML = "<b>Status:</b> Realigning sattelites" http.open("GET", "alg.aspx?cr=8&cc=7&sq=3,3", true); http.send(null); } This code sort of works, but the querystring data isn't being passed through. It keeps returning an ASPX error page which only happens when there is no querystring data. Thanks for any help

  • Alternative to jQuery .data()?

    - by thebossman
    I'm a big fan of jQuery's .data() method, but I can't always use it. Often times I am rendering html templates that I pass via AJAX and I need to attach metadata to each of the elements in the template. For example: <ul> {% for item in itemlist %} <li metadata="{{ item.metadata }}">{{ item.name }}</li> {% endfor %} </ul> I know attaching attributes to store data is bad practice (and it might not even work in older versions of IE). What is the best practice? Is there a good alternative to this method?

  • Using jQuery to make a group of images appear in order.

    - by Sean Johnson
    I have a page that shows a bunch of thumbnails (around 30), and the client is wanting them to appear one by one, in order, going from left to right on the page. This is what I've tried: var start_opacity = 500; $j('.grid-photo').each(function(i) { start_opacity = start_opacity + 500; setTimeout(function() { $j(i).animate({opacity: 1}, 4000); }, start_opacity); }); It doesn't seem to know what i is referencing. Any thoughts?

  • I don't get this C/C++ Joke

    - by Buttercup
    After reading this article on thedailywtf.com, I'm not sure that I really got the joke. It says there that some guy changed the code from int function() { int x; char data_string[15]; ... x = 2; strcpy(data_string,"data data data"); ... } to int function() { int x = 2; char data_string[15] = "data data data"; ... } everywhere in the code and that for some reason did inflate the size of the executable from 1 to 2 CDs (or maybe it didn't do that?). Obviously I'm not familiar enough with C/C++ to get this joke, but what seems strangest is that the 2nd code listing seems "cleaner"—at least from what I've been told in school (that is that initializing variables is a good thing, not a bad one).

  • Codeigniter - Is it ok to add functionality to the constructor in controllers?

    - by Irro
    I'm making a project where I want the user to search for shops in different cities and would like the url to be like this: domain/shop/city/name. So I created a controller in codeigniter called Shop. But I cant create a city function since the city part of the url changes dependent on city name. One easy way to do it would be to add a function called "search" and add the functionality there but then I get url's like: domain/shop/search/city/name which I really would like to avoid. So my question is if it's ok to add my functionality directly into the constructor to avoid that extra "search" part in the url? I'm afraid that there might be some performance tricks involved that potentially keeps the class in memory so the constructor will not be called every time.

  • Jquery: encasing div and anchor link binded to same event.

    - by centr0
    im having trouble figuring out how to bind mouseout() to my entire nav bar including the links. when a user hovers over a link in #nav a sub menu is shown. all is well there. what i want to do is fadeOut that sub menu when the user hovers out of the entire #nav. my code for the mouseout: $('#nav').mouseout(function() { setTimeout(function() { //$('.sub-link').fadeOut(); }, 2000); }); when i hover over an anchor link which resides in #nav, i see the sub-menu. then i guess the mouseout() even fires and the sub-menu fades out. is there anyway to have the #nav and any anchor links within it to act as one? i'd paste my markup but even indenting it 4 spaces still shows as rendered html.. TIA

  • Stop jQuery animations stacking

    - by Chris
    I have an Options box that hovers in the top right of the webpage. It's opacity is set to 10% so as not to be obstructive to users. When they hover over (mouseenter) it I use jQuery to fade it in and slidedown the content (and the reverse on mouseout). If they do this repeatedly though the animation stacks up and you can sometimes be left in a situation where your mouse is stood still but the box is yo-yoing around. How can I get around this situation? Here is how I currently setup the animations $("#dropdown").mouseenter(function() { $(this).fadeTo('fast',1); $("#options").slideDown(); }); $("#dropdown").mouseleave(function() { $(this).fadeTo('fast',0.1); $("#options").slideUp(); }); Note I am using jQuery only and not any other plugins.

  • Using generics in dotnet for functions with any number of arguments?

    - by Zarigani
    I would like to have a function that can "wrap" any other function call. In this particular case, it would allow me to write some more generic transaction handling around some specific operations. I can write this for any particular number of arguments, e.g. for one argument: Public Shared Sub WrapFunc(Of T)(ByVal f As Action(Of T), ByVal arg As T) ' Test some stuff, start transaction f(arg) ' Test some stuff, end transaction End Sub ... but I was hoping to have this handle any number of arguments without having to have duplicate code for 0 args, 1 arg, 2 args, etc. Is there a way of doing this?

  • Insert A Line At The Beginnig Of A File

    - by thebourneid
    I'm trying to insert/add a line 'COMMENT DUMMY' at the beginnig of a file as a first row if /PATTERN/ not found. I know how to do this with OPEN CLOSE function. Probably after reading the file it should look something like this: open F, ">", $fn or die "could not open file: $!"; ; print F "COMMENT DUMMY\n", @array; close F; But I have a need to implement this with the use of the Tie::File function and don't know how. use strict; use warnings; use Tie::File; my $fn = 'test.txt'; tie my @lines, 'Tie::File', $fn or die "could not tie file: $!"; untie @lines;

  • Apache Rewrite Excluding Assets Directory

    - by Midiane
    Hi all I'm writing a mini-MVC application. App architecture: actions/ templates/ site/ app/ styles/ images/ scripts/ So far, I've got a controller working properly, taking in all requests. However, javascript files are not being rendered properly in the browser; I'm getting a 404 Not Found when I try to load the file in the browser. Here is my current Directory config in a vhost file: DirectoryIndex index.php RewriteEngine On RewriteBase /apps/ecatalogue RewriteRule ^scripts/(.*) - [NC,L] <--- Rule not working RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [NC,L,QSA] I can confirm everything else works; I just need apache to ignore anything in scripts so the file can be loaded normally without being processed by the controller. Your help is appreciated.

  • jQuery: use filter(), but work with both results

    - by Tomalak
    In jQuery, filter() reduces your result to those elements that fulfill a certain condition. This splits the list in two parts. Working with the "good half" of the elements is easy: $("some selector").filter(function() { // determine result... return result; }).each( /* do something */ ); But how can I work with the "other half" of my elements, too - but without doing the equivalent of this: $("some selector").filter(function() { // determine result... return !result; }).each( /* do something */ ); Basically, I'd like to feed two separate /* do something */ parts to a single filter. One for those that match, and one for the others - without having to select and filter twice.
