  • .htaccess trickery multi-language website

    - by user1658741
    I have a website right now that uses two languages (french and english) The way it works right now is that if someone goes to mysite.com/folder/file.php for example, file.php is simply a script that figures out which language to use, get's it's own path and filename(file.php) and serves up mysite.com/en/folder/file.php (if the language is english). However what shows up in the URL is still mysite.com/folder/file.php. For any folder and any file the same script is used. If I want to add a new file I have to add the file to the folder the user types into the browser as well to the en and fr folders. Could I do some .htaccess trickery so that whatever URL is typed, one .php file gets open that checks the language and what folder/file was requested and then serves up the correct language file? here's the php file that is served up for any files in the URL. <?php // Get current document path which is mirrored in the language folders $docpath = $_SERVER['PHP_SELF']; // Get current document name (Used when switching languages so that the same current page is shown when language is changed) $docname = GetDocName(); //call up lang.php which handles display of appropriate language webpage. //lang.php uses $docpath and $docname to give out the proper $langfile. //$docpath/$docname is mirrored in the /lang/en and /lang/fr folders $langfile = GetDocRoot()."/lang/lang.php"; include("$langfile"); //Call up the proper language file to display function GetDocRoot() { $temp = getenv("SCRIPT_NAME"); $localpath=realpath(basename(getenv("SCRIPT_NAME"))); $localpath=str_replace("\\","/",$localpath); $docroot=substr($localpath,0, strpos($localpath,$temp)); return $docroot; } function GetDocName() { $currentFile = $_SERVER["SCRIPT_NAME"]; $parts = Explode('/', $currentFile); $dn = $parts[count($parts) - 1]; return $dn; } ?>

  • getClientRects javascript method supported on iPhone?

    - by genericdan
    Trying to find the top-most visible element in a UIWebView. I am using a JS method to do this, which works great in Safari, but never executes past the getClientRects method when executed from a UIWebView. The elements I'm interested are all of class="h". Here's the javascript which is called from [webView stringByEvaluatingJavaScriptFromString:@"findTopElement()"]; Javascript: function findTopElement() { var pars = document.getElementsByClassName("h"); alert("findingTopElement: num pars:" + pars.length); for (var i = 0; i < pars.length; i++) { var para = pars[i]; alert("checking par " + para.id); var rects = para.getClientRects(); alert("checking rects " + rects.length); for (var j = 0; j < rects.length; j++) { var r = rects[j]; if (r.top > 0 && r.bottom > 0) { alert("success: " + para.id); return para.id; } } } return -1; } Is it possible element getClientRects function is not supported in a UIWebView?

  • Jquery + Prototype Question

    - by mikeyhill
    I recently inherited a site which is botched in all sorts of ways. I'm more of a php guy and initially the js was working just fine. I made no changes to the javascript or the any of the include files but after making a few content edits I'm getting errors from firebug. a.dispatchEvent is not a function emptyFunction()protot...ects.js (line 2) emptyFunction()protot...ects.js (line 2) fireContentLoadedEvent()protot...ects.js (line 2) [Break on this error] var Prototype={Version:'1.6.0.2',Brows...pe,Enumerable);Element.addMethods(); protot...ects.js (line 2) this.m_eTarget.setStyle is not a function [Break on this error] this.m_eTarget.setStyle( { position: 'relative', overflow:'hidden'} ); protot...ects.js (line 43) uncaught exception: [Exception...

The previous developer incorporated a head.inc file which loads up prototype, scriptaculous and then many of the pages are in a sub-template loading up jquery for functions like lightbox. The site is temp housed at http://dawn.mikeyhill.com Any help is appreciated.

  • How to store a captured image into MySQL database using JavaScript

  • whether rand_r is real thread safe?

    - by terry
    Well, rand_r function is supposed to be a thread safe function. However, by its implementation, I cannot believe it could make itself not change by other threads. Suppose that two threads will invoke rand_r in the same time with the same variable seed. So read-write race will occur. The code rand_r implemented by glibc is listed below. Anybody knows why rand_r is called thread safe? int rand_r (unsigned int *seed) { unsigned int next = *seed; int result; next *= 1103515245; next += 12345; result = (unsigned int) (next / 65536) % 2048; next *= 1103515245; next += 12345; result <<= 10; result ^= (unsigned int) (next / 65536) % 1024; next *= 1103515245; next += 12345; result <<= 10; result ^= (unsigned int) (next / 65536) % 1024; *seed = next; return result; }

  • Is long long in C++ known to be very nasty in terms of precision?

    - by Kevin
    The Given Problem: Given a theater with n rows, m seats, and a list of seats that are reserved. Given these values, determine how many ways two friends can sit together in the same row. So, if the theater was a size of 2x3 and the very first seat in the first row was reserved, there would be 3 different seatings that these two guys can take. The Problem That I'm Dealing With The function itself is supposed to return the number of seatings that there are based on these constraints. The return value is a long long. I've gone through my code many many times...and I'm pretty sure that it's right. All I'm doing is incrementing this one value. However, ALL of the values that my function return differ from the actual solution by 1 or 2. Any ideas? And if you think that it's just something wrong with my code, please tell me. I don't mind being called an idiot just as long as I learn something.

  • Extended Zend_Db_Table_Row_Abstract does not return values

    - by WesleyE
    Hi, I'm quite new to Zend and the database classes from it. I'm having problems mapping a Zend_Db_Table_Row_Abstract to my rows. The problem is that whenever I try to map it to a class (Job) that extends the Zend_Db_Table_Row_Abstract class, the database data is not receivable anymore. I'm not getting any errors, trying to get data simply returns null. Here is my code so far: Jobs: class Jobs extends Zend_Db_Table_Abstract { protected $_name = 'jobs'; protected $_rowsetClass = "Job"; public function getActiveJobs() { $select = $this->select()->where('jobs.jobDateOpen < UNIX_TIMESTAMP()')->limit(15,0); $rows = $this->fetchAll($select); return $rows; } } Job: class Job extends Zend_Db_Table_Row_Abstract { public function getCompanyName() { //Gets the companyName for this row (Is on another table), just for example } } Controller: $oJobs = new Jobs(); $aActiveJobs = $oJobs->getActiveJobs(); foreach ($aActiveJobs as $value) { var_dump($value->jobTitle); } When I remove the "protected $_rowsetClass = "Job";" line, so that the table row is not mapped to my own class, I get all the jobTitles perfectly. What am I doing wrong here? Thanks in advance, Wesley

  • Iphone -- maintaining a list of strings and a corresponding typedef enum

    - by William Jockusch
    Suppose I have the following: typedef enum functionType {ln, sin, sqrt} functionType; NSArray *functions = [NSArray arrayWithObjects: @"ln", @"sin", @"sqrt", nil]; Suppose further that *functions will not change at runtime. Question -- is there any way to set up a single structure which updates both of these? So that I only have to keep track of one list, instead of two. To explain what is going on -- the idea is that string input from the user will be stored in a variable of type functionType. Later on, I will have code like this: double valueOfFunction: (functionType) function withInput: (double) input switch (function) { case ln: return ln(input); case sin: return sin(input); case sqrt: return sqrt(input); //etc . . . could grow to include a lot of functions. } And valueOfFunction needs to be fast. So I don't want to be doing string comparisons there.

  • Show/hide rows with jquery

    - by Mike
    Hi I am using some modified code from another post. Basically I want to switch between showing 10 rows of a table to showing all rows (50 for example). I have got it to show from 10 rows to all, however what I need to do now is code it so that if I click the div again it toggles or resets back to showing 10 rows. <script type="text/javascript"> var numShown = 10; // Initial rows shown & index var numRows = $('tbody').find('tr').length; var numLeft = numRows - numShown; $(document).ready(function(){ // Hide rows and add clickable div $('tbody') .find('tr:gt(' + (numShown - 1) + ')').hide().end() $('#table_wrapper').after('<div id="more">Show all offers <span>(' + numLeft + ' more)</span></div>'); $('#more').click(function(){ numShown = numShown + numRows; // 7 + 1 = 8 $('tbody').find('tr:lt('+numShown+')').show(); $("#more").html("Show top 10 offers"); }) }) </script>

  • Performance difference between functions and pattern matching in Mathematica

    - by Samsdram
    So Mathematica is different from other dialects of lisp because it blurs the lines between functions and macros. In Mathematica if a user wanted to write a mathematical function they would likely use pattern matching like f[x_]:= x*x instead of f=Function[{x},x*x] though both would return the same result when called with f[x]. My understanding is that the first approach is something equivalent to a lisp macro and in my experience is favored because of the more concise syntax. So I have two questions, is there a performance difference between executing functions versus the pattern matching/macro approach? Though part of me wouldn't be surprised if functions were actually transformed into some version of macros to allow features like Listable to be implemented. The reason I care about this question is because of the recent set of questions (1) (2) about trying to catch Mathematica errors in large programs. If most of the computations were defined in terms of Functions, it seems to me that keeping track of the order of evaluation and where the error originated would be easier than trying to catch the error after the input has been rewritten by the successive application of macros/patterns.

  • Replace field value(s) in a String

    - by xybrek
    Using Google Guava is there String utility to easily replace string field inside like this: String query = mydb..sp_mySP ${userId}, ${groupId}, ${someOtherField} Where I can do something like this: StringUtil.setString(query) .setField("userId", "123") .setField("groupId", "456") .setField("someOtherField", "12-12-12"); Then the resulting String would be: mydb..sp_mySP 123, 456, 12-12-12 Of course, setting the String field patter like ${<field>} before the operation... Anyway, this is my approach: public class StringUtil { public class FieldModifier { private String s; public FieldModifier(String s){ this.s = s; } public FieldModifier setField(String fieldName, Object fieldValue){ String value = String.valueOf(fieldValue); s = modifyField(s, fieldName, value); return new FieldModifier(s); } private String modifyField(String s, String fieldName, String fieldValue){ String modified = ""; return modified; } } public FieldModifier parse(String s){ FieldModifier fm = new FieldModifier(s); return fm; } } So in this case, I just need to put the actual code in the modifyField function that will modify the string in a straightforward way. Also if there's a way so the parse function be static so I can just do StringUtil.parse(...) without doing new StringUtil().parse(...) which really doesn't look good.

  • Detect modification of variable at runtime in C/C++

    - by YuppieNetworking
    Hello, I am developing a library in C++ where users/programmer will extend a class BaseClass that has a method initArray. This method should be implemented by the user/programmer and it should normally initialize all elements of the array m_arr. Here is a snipplet, modified to this example: class BaseClass { public: BaseClass(int n) { m_arr = new double[n]; size = n; }; virtual ~BaseClass(); int size; double* m_arr; virtual int initArray(); }; Sometimes, the user/programmer implements a initArray that does not initialize some elements of m_arr. What I would like is to create a function in my library that checks if initArray did initialize all elements of m_arr. This function should be called by a sanity-check rutine at runtime. My question: is it possible to detect changes on this array? I can only think of initializing the array with some invalid values (like NaN or Inf), call initArray and check that all values have changed. Thanks for your ideas, David

  • How to prevent onclick statements from being executed?

    - by ryanli
    I want to use an event listener for preventing the onclick statement of a submit button, however, using event.preventDefault() doesn't work as intended. The code is like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="application/x-javascript"> function addListener() { document.getElementById("submit").addEventListener("click", function(ev) { alert("listener"); ev.preventDefault(); }, false); } </script> <title></title> </head> <body onload="addListener();"> <form id="form" method="post" target=""> <input type="submit" id="submit" onclick="alert('onclick')" value="test" /> </form> </body> </html> The expected behaviour is only "listener" will be alerted, but in practice (Firefox 3.7a5pre), "onclick" and "listener" are both alerted, in the given order. It seems that onclick is being executed before the listener, so event.preventDefault() doesn't work. Is there a way to prevent onclick from being executed?

  • In C, when do structure names have to be included in structure initializations and definitions?

    - by Tyler
    I'm reading The C Programming Language by K&R and in the section on structures I came across these code snippets: struct maxpt = { 320, 200 }; and /* addpoints: add two points */ struct addpoint(struct point p1, struct point p2) { p1.x += p2.x; p1.y += p2.y; return p1; } In the first case, it looks like it's assigning the values 320 and 200 to the members of the variable maxpt. But I noticed the name of the struct type is missing (shouldn't it be "struct struct_name maxpt = {320, 200}"? In the second case, the function return type is just "struct" and not "struct name_of_struct". I don't get why they don't include the struct names - how does it know what particular type of structure it's dealing with? My confusion is compounded by the fact that in previous snippets they do include the structure name, such as in the return type for the following function, where it's "struct point" and not just "struct". Why do they include the name in some cases and not in others? /* makepoint: make a point from x and y components */ struct point makepoint(int x, int y) { struct point temp; temp.x = x; temp.y = y; return temp; }

  • jQuery - Moving background arrow in menu

    - by B M
    I would expect something like this to be pretty popular in demand but I had much trouble finding a suiting script. I've got a basic menu build like this: <div id="menu"> <ul> <li><a href="#"><img src="images/btn1.png"></a></li> <li><a href="#"><img src="images/btn2.png"></a></li> <li><a href="#"><img src="images/btn3.png"></a></li> </ul> </div> The div #menu has a background image of a small arrow. I want the arrow to move vertically in front of the corresponding menu image when you mouseover/mousemove the whole #menu div. Also when one of the menu images has been clicked the arrow should stay in it's position in front of the corresponding menu image. I started something but I notice it's going downwards, since it's only working when you're at the top of the page. What I have is this: $('#menu').css({backgroundPosition: '5px 10px'}); //Starting position $('#menu').mousemove(function(e){ $('#menu').stop().animate( {backgroundPosition: '5px ' + (e.pageY-60) + ' px'}, {duration:100} ) }).mouseout(function(){ $('#menu').stop().animate( {backgroundPosition: '5px 10px'}, {duration:100} ) }); Please help! ps. I'm using this plugin to move background images smoothly.

  • Trouble with jQuery Form Validation

    - by Sennheiser
    I'm making a form that has the following validation rules: no fields are "required", but if you enter an email, it must be valid, and if you enter a password, it must be at least 6 characters and match the confirm password field value. The form works flawlessly with no validation so I know it's not a PHP or HTML problem. Here's the jQuery code handling the form: $('#success').hide(); $('#pwerror').hide(); $('#emailError').hide(); $('#subSet').live('click',function() { //if any of the fields have a value if($("#chfn").val() != "" || $("#chln").val() != "" || $("#chpw").val() != "" || $("#chpw2").val() != "" || $("#chem").val() != "") { $ev = 1; $pv = 1; //validates an email if there is one, trips the valid variable flag if($("#chem").val() != "") { $("#profSet").validate({ rules: { chem: { email: true }, chpw: { required: false, minlength: 6 }, chpw2: { required: false, minlength: 6, equalTo: $("#chpw").val() } }, messages:{ chpw2: { equalTo: "Passwords must be the same." }, chpw: { minlength: "Password must be at least 6 characters." } } }); if(!($("#profSet").valid())) { $ev = 0; } } //if either password field is filled, start trying to validate it if($("#chpw").val() != "" || $("#chpw2").val() != "") { if(!($("#profSet").valid())) { $pv = 0; } } //if those two were valid if($pv == 1 && $ev == 1) { $.post('php/profSet.php', $('#profSet').serialize(), function(){ $('#profSet').hide(); $('#success').show(); }); } //if either was invalid, the error was already tripped, and this code exits here } }); The problem I'm having now is that the "passwords must be the same" error keeps getting triggered even if both fields are blank, or if they actually are the same. Therefore, the form cannot submit. Any help?

  • jQuery class selector and click()

    I'm currently trying to get an alert to happen when something is clicked. I can get it working in jsFiddle, but not in production code: jsFiddle example that works (jQuery 1.5 loaded) HTML (in case jsFiddle is inaccessible): <!DOCTYPE HTML><html><head><title>Test</title></head> <body> <h1>25 Feb 2011</h1><h3>ABC</h3><ul> <li class="todoitem">Test&mdash;5 minutes</li> </ul> </body></html> Javascript: $(".todoitem").click(function() { alert('Item selected'); }); Non-working production example: <!DOCTYPE HTML><html><head><title>Test</title> <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.1.min.js" type="text/javascript"></script> <script type="text/javascript"> $(".todoitem").click(function() { alert('Item selected'); }); </script> </head> <body> <h1>25 Feb 2011</h1><h3>ABC</h3><ul><li class="todoitem">Test&mdash;5 minutes</li></ul> </body> </html> Safari's Inspector indicate that jQuery is being loaded correctly, so that's not the issue. As far as I can tell, these two pieces of code are essentially identical, but the latter isn't working. Can anyone see what I've done wrong?

  • AngularJS Templates run twice

    - by Curt
    I'm working on an AngularJS web app with Twitter Bootstrap. The templates run twice. I don't know why they do this. Below is some of the code in the index.html file: <html data-ng-app="app" ng-controller="AppCtrl"> <div class="container ng-view" data-ng-view></div> ... <script> (function (angular) { "use strict"; // jshint ;_; // http://coenraets.org/blog/2012/02/sample-application-with-angular-js/ angular.module('app', ['filters', 'angular', 'currency']) .config(function($routeProvider) { var _view_ = 'view/'; $routeProvider. when('/app', {templateUrl:_view_+'app/index.html', }). when('/account/settings', {templateUrl:_view_+'app/settings.html', }). when('/profile/:profile_ID', {templateUrl:_view_+'app/profile.html', controller:ProfilePageCtrl}). when('/discuss', {templateUrl:_view_+'discuss/discuss.html', controller:DiscussCtrl}). when('/', {templateUrl:_view_+'page/home.html' }). when('/:page', {templateUrl:_view_+'page.html', controller:PageCtrl}). otherwise({redirectTo:'/'}); }) ... Can anybody provide suggestions? Are the templates supposed to run twice? 2012-12-04 Update: I found out that the templates are running twice, not the controller.

  • Prevent event from parent element to child element in jquery

    - by sonam
    I have binded event as below: $(document).delegate('.budget', 'click', function(e){ if ($(this).hasClass('collapsed')) { $(this).removeClass('collapsed'); $(this).addClass('expanded'); } else if ($(this).hasClass('expanded')) { $(this).removeClass('expanded'); $(this).addClass('collapsed'); } }); Basically this toggles between expand and collapse. I have another event binded as below: $('[id^="tree"]').delegate('.collapsed', 'click', function(e){ var elementId = $(this).attr('id'); hideChildElement(elementId); }); The elements binded by the second event binding are parents of elements binded by first event binding. What happens is that on clicking on the element from the first binding event method also triggers the event binded by second event binding. I want to prevent any events from binding from second event binding to 1st event binding method. If element A is binded to click event from first event binding and B is binded to second event binding (A is inside B or A is child of B), I dont want any event of B to propagate to A. Note I tried e.stopImmediatePropagation(); but did not worked

  • jQuery .load() call doesn't execute javascript in loaded html file

    - by Mike
    This seems to be a problem related to Safari only. I've tried 4 on mac and 3 on windows and am still having no luck. What I'm trying to do is load an external html file and have the Javascript that is embedded execute. The code I'm trying to use is this: $("#myBtn").click(function() { $("#myDiv").load("trackingCode.html"); }); trackingCode.html looks like this (simple now, but will expand once/if I get this working): <html> <head> <title>Tracking HTML File</title> <script language="javascript" type="text/javascript"> alert("outside the jQuery ready"); $(function() { alert("inside the jQuery ready"); }); </script> </head> <body> </body> </html> I'm seeing both alert messages in IE (6 & 7) and Firefox (2 & 3). However, I am not able to see the messages in Safari (the last browser that I need to be concerned with - project requirements - please no flame wars). Any thoughts on why Safari is ignoring the Javascript in the trackingCode.html file? Eventually I'd like to be able to pass Javascript objects to this trackingCode.html file to be used within the jQuery ready call, but I'd like to make sure this is possible in all browsers before I go down that road. Thanks for your help!

  • Rails - Create if record doesn't exist or else update.....Whats Best way to do this?

    - by ChrisWesAllen
    Hi, I have a create statement for some models but its creating a record within a join table regardless if the record exist. Here is what my code looks like. @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is it creates records no matter what. I would like it to create a record if it doesnt exist, if a record does exist I would just to it to take the attribute of the found record and add or subtract 1. So, I've been looking around and I see something called find_or_create_by. My question is what happens if it finds? Preferably if it finds,I would like to take the current :score attribute and +1. SO is it possible to find or create by id? I'm not sure what attribute I would find by since the model I'm looking at is a join model which only had id foreign keys and the score attribute. I tried @user.choices.find_or_create_by_user(:user => @user.id, :interest => interest, :score => 4) but got "undefined method `find_by_user'".....ANy ideas or help?

  • GTK+: How do I process RadioMenuItem choice without marking it chosen? And vise versa

    - by eugene.shatsky
    In my program, I've got a menu with a group of RadioMenuItem entries. Choosing one of them should trigger a function which can either succeed or fail. If it fails, this RadioMenuItem shouldn't be marked chosen (the previous one should persist). Besides, sometimes I want to set marked item without running the choice processing function. Here is my current code: # Update seat menu list def update_seat_menu(self, seats, selected_seat=None): seat_menu = self.builder.get_object('seat_menu') # Delete seat menu items for menu_item in seat_menu: # TODO: is it a good way? does remove() delete obsolete menu_item from memory? if menu_item.__class__.__name__ == 'RadioMenuItem': seat_menu.remove(menu_item) # Fill menu with new items group = [] for seat in seats: menu_item = Gtk.RadioMenuItem.new_with_label(group, str(seat[0])) group = menu_item.get_group() seat_menu.append(menu_item) if str(seat[0]) == selected_seat: menu_item.activate() menu_item.connect("activate", self.choose_seat, str(seat[0])) menu_item.show() # Process item choice def choose_seat(self, entry, seat_name): # Looks like this is called when item is deselected, too; must check if active if entry.get_active(): # This can either succeed or fail self.logind.AttachDevice(seat_name, '/sys'+self.device_syspath, True) Chosen RadioMenuItem gets marked irrespective of the choose_seat() execution result; and the only way to set marked item without triggering choose_seat() is to re-run update_seat_menu() with selected_seat argument, which is an overkill. I tried to connect choose_seat() with 'button-release-event' instead of 'activate' and call entry.activate() in choose_seat() if AttachDevice() succeeds, but this resulted in whole X desktop lockup until AttachDevice() timed out, and chosen item still got marked.

  • Consecutive calls/evaulations in a form?

    Hey guys, simple question... Working with XLISP to write a program, but I've seemed to run into a simple fundamental problem that I can't seem to work around: perhaps someone has a quick fix. I'm trying to write an if statement who's then-clause evaluates multiple forms and returns the value of the last. In example: (setq POSITION 'DINING-ROOM) (defun LOOK (DIRECTION ROOM) ... ) (defun SETPOS (ROOM) ... ) (defun WHERE () ... ) (defun MOVE (DIRECTION) (if (not(equal nil (LOOK DIRECTION POSITION))) ; If there is a room in that direction ( ; Then-block: Go to that room. Return where you are. (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) ( ; Else-block: Return error (list 'CANT 'GO 'THERE) ) ) The logical equivalent intended is: function Move (Direction) { if(Look(Direction, Room) != null) { SetPos(Look(Direction,Room)); return Where(); } else { return "Can't go there"; } } (Apologies for the poor web-formatting.) The problem I have is with: ( (SETPOS (LOOK DIRECTION ROOM)) (WHERE) ) I simply want to return the evaluation of WHERE, but I need to execute the SETPOS function first. XLISP doesn't like the extra parentheses: if I remove the outer set, my WHERE list becomes my else (I don't want that). If I remove the sets around SETPOS and WHERE, it treats WHERE like an argument for SETPOS; I also don't want that. So, how do I simply evaluate the first, then the second and then return the values of the last evaluated?

  • Portable way of counting milliseconds in C++ ?

    - by ereOn
    Hi, Is there any portable (Windows & Linux) way of counting how many milliseconds elapsed between two calls ? Basically, I want to achieve the same functionnality than the StopWatch class of .NET. (for those who already used it) In a perfect world, I would have used boost::date_time but that's not an option here due to some silly rules I'm enforced to respect. For those who better read code, this is what I'd like to achieve. Timer timer; timer.start(); // Some instructions here timer.stop(); // Print out the elapsed time std::cout << "Elapsed time: " << timer.milliseconds() << "ms" << std::endl; So, if there is a portable (set of) function(s) that can help me implement the Timer class, what is it ? If there is no such function, what Windows & Linux API should I use to achieve this functionnality ? (using #ifdef WINDOWS-like macros) Thanks !
