• Zend Namespace - Check if Session Exists

  - by Vincent

  All, I am using Zend Framework and Zend_Session to do global session management for my application. I plan to clear all sessions on logout and hence am using the following code: if($this->sessionExists()) { $this->destroy(); } But it seems like it's not doing a good job.. I am getting an error: PHP Warning: session_destroy() [<a href='function.session-destroy'> function.session-destroy</a>]: Trying to destroy uninitialized session How can I get rid of this error? Is there an alternative to sessionExists()?

• Temporarily Disallow JQuery Toggle

  - by Kevin Sylvestre

  I have a menu that is toggled when a user selects a link. The menu has an animation attached, and I want to prevent toggling while the animation is running. The following snippet works, but flips the state of toggle if the link is clicked quickly twice (i.e. if the user clicks the link quickly twice, the next click will trigger the same action): <a href="" id="button">Menu</a> <div id="menu">...</a> <script> $("#button").toggle( function (e) { if $("#menu").is(":animated")) return false; $menu.show("slow"); }, function (e) { if ("#menu").is(":animated")) return false; $menu.hide("slow"); } ); </script> How can I prevent switching states within toggle? Thanks.

• Is there any way to get Visual Studio 2008 to update .net style comments automatically?

  - by Jon Cage

  I've been writing a lot of VC++ 2008 / CLI software recently and am using the C#/CLI style documentation: /// <summary> /// Function the does stuff /// </summary> /// <param name="someParam">Specifies some option</param> /// <returns>true if it worked</returns> bool DoStuff( bool someParam ); I find myself re-typing those blocks quite frequently and frankly, it's getting repetitive. Is there any way to get Visual Studio to create / update those blocks automatically as you create new function definitions or update existing definitions?

• In Python, is there a way to call a method on every item of an iterable? [closed]

  - by Thane Brimhall

  Possible Duplicate: Is there a map without result in python? I often come to a situation in my programs when I want to quickly/efficiently call an in-place method on each of the items contained by an iterable. (Quickly meaning the overhead of a for loop is unacceptable). A good example would be a list of sprites when I want to call draw() on each of the Sprite objects. I know I can do something like this: [sprite.draw() for sprite in sprite_list] But I feel like the list comprehension is misused since I'm not using the returned list. The same goes for the map function. Stone me for premature optimization, but I also don't want the overhead of the return value. What I want to know is if there's a method in Python that lets me do what I just explained, perhaps like the hypothetical function I suggest below: do_all(sprite_list, draw)

• OpenGL in Visual studio - Issues with GLEW

  - by BalsamicVinegar

  I'm currently following the openglbook.com tutorials (set up) (Tutorial) and have run into an issue fairly early on. I'm getting the following two errors: 1>main.obj : error LNK2019: unresolved external symbol __imp__glewGetErrorString@4 referenced in function _Initialize 1>main.obj : error LNK2019: unresolved external symbol __imp__glewInit@0 referenced in function _Initialize I have downloaded and compiled freeglut 2.8.0 as well as the glew 1.9.0 binaries. I have copied the libs and includes to C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Lib and Include respectively. The Lib and Include paths have also been added to my project properties under Additional Library/Include directories. I have also defined glew32.lib and freeglut.lib in my linker-Input-Additional dependencies. I have included and at the top of my main file. What am I missing? Every other thread I've found has been solved by adding the directories to the project properties. Does anyone have any ideas?

• CSS Position Help (horizontal sidebar showing up when animate content over)

  - by jstacks

  Let me try my best to explain what I'd like to have happen, show you the code I have an hopefully I can get some help. So, I'm trying to do a sliding navigation UI from the left side of the screen (like a lot of mobile apps). The main content slides over, displaying the navigation menu beneath. Right now the browser thinks the screen is getting wider and introduces a horizontal scroll bar. However, I don't want that to happen... How do I get the div to animate off screen but not enlarge the width of the screen (i.e. keep it partially off screen)? Anyway here is my fiddle: http://jsfiddle.net/2vP67/6/ And here is the code within the post: HTML <div id='wrapper'> <div id='navWide'> </div> <div id='containerWide'> </div> <div id='containerTall'> <div id='container'> <div id='nav'> <div id='navNavigate'> Open Menu </div> <div id='navNavigateHide'> Close Menu </div> </div> </div> </div> <div id='sideContainerTall'> <div id='sideContainer'> <div id='sideNav'>Side Navigation </div> </div> </div> </div> CSS #wrapper { width:100%; min-width:1000px; height:100%; min-height:100%; position:relative; top:0; left:0; z-index:0; } #navWide { color: #ffffff; background:#222222; width:100%; min-width:1000px; height:45px; position:fixed; top:0; left:0; z-index:100; } #containerWide { width:100%; min-width:1000px; min-height:100%; position:absolute; top:45px; z-index:100; } #containerTall { color: #000000; background:#dadada; width:960px; min-height:100%; margin-left:-480px; position:absolute; top:0; left:50%; z-index:1000; } /***** main container *****/ #container { width:960px; min-height:585px; } #nav { color: #ffffff; background:#222222; width:960px; height:45px; position:fixed; top:0; z-index:10000; } #navNavigate { background:yellow; font-size:10px; color:#888888; width:32px; height:32px; padding:7px 6px 6px 6px; float:left; cursor:pointer; } #navNavigateHide { background:yellow; font-size:10px; color:#888888; width:32px; height:32px; padding:7px 6px 6px 6px; float:left; cursor:pointer; display:none; } #sideContainerTall { background:#888888; width:264px; min-height:100%; margin-left:-480px; position:absolute; top:0; left:50%; z-index:500; } #sideContainer { width:264px; min-height:585px; display:none; } #sideContainerTall { background:#888888; width:264px; min-height:100%; margin-left:-480px; position:absolute; top:0; left:50%; z-index:500; } #sideContainer { width:264px; min-height:585px; display:none; } #sideNav { width:264px; height:648px; float:left; } Javascript $(document).ready(function() { $('div#navNavigate').click(function() { $('div#navNavigate').hide(); $('div#navNavigateHide').show(); $('div#sideContainer').show(); $('div#containerTall').animate({ 'left': '+=264px' }); }); $('div#navNavigateHide').click(function() { $('div#navNavigate').show(); $('div#navNavigateHide').hide(); $('div#containerTall').animate({ 'left': '-=264px' }, function() { $('div#sideContainer').hide(); }); }); });

• Passing User Data with SetTimer

  - by GJ

  I am calling SetTimer in a function of a Class. SetTimer(NULL, 0, 10000, (TIMERPROC) TimerCallBack); Where TimerCallBack is: static VOID CALLBACK TimerCallBack(HWND, UINT, UINT, DWORD) Now my need is to call one of the method of class which initiated timer, since TimerCallBack is static it has no access to the class object anymore. I cant find any way to pass object pointer along with the SetTimer so that I can receive it back on Callback function. Is there any other way to achieve this, if its not supported using SetTimer then which other way I can implement this.

• How does the stream manipulators work?

  - by Narek

  It is well known that the user can define stream manipulators like this: ostream& tab(ostream & output) { return output<< '\t'; } And this can be used in main() like this: cout<<'a'<<tab<<'b'<<'c'<<endl; Please explain me how does this all work? If operator<< assumes as a second parameter a pointer to the function that takes and returns ostream &, then please explain my why it is necessary? What would be wrong if the function does not take and return ostream & but it was void instead of ostream &? Also it is interesting why “dec”, “hex” manipulators take effect until I don’t change between them, but user defined manipulators should be always used in order to take effect for each streaming?

• Inserting text into a textarea using .load() in jQuery

  - by bateman_ap

  Hi, having a bit of a nightmare, I am trying to use jQuery to insert some text taken from a .load() call into a form field (textfield) after a user logs in (basically prefilling some known details) The code I am using is: $.ajax({ type: "POST", url: "/ajax/login.php", data: dataString, success: function(html) { if (html == 1) { $("#loginPanel").load("/ajax/login-panel.php"); $("#bookName").load("/ajax/getSessionDetails.php #userUsername"); $("#bookEmail").load("/ajax/getSessionDetails.php #userEmail"); $("#bookingLogin").hide("fast"); } else { $("#loginError").html("Sorry, login failed, please try again"); } } }); If I hardcode such as $("#bookName").html("Test Content"); it works OK so it must be a problem with the .load call. I looked around and found some guy suggest something like the following code but I couldn't get it to work: $.get(htmlBannerUrl, function(data){ $('textarea').val(data); });

• What is the role of `while`-loops in computation expressions in F#?

  - by MizardX

  If you define a While method of the builder-object, you can use while-loops in your computation expressions. The signature of the While method is: member b.While (predicate:unit->bool, body:M<'a>) : M<'a> For comparison, the signature of the For method is: member b.For (items:seq<'a>, body:unit->M<'a>) : M<'a> You should notice that, in the While-method, the body is a simple type, and not a function as in the For method. You can embed some other statements, like let and function-calls inside your computation-expressions, but those can impossibly execute in a while-loop more than once. builder { while foo() do printfn "step" yield bar() } Why is the while-loop not executed more than once, but merely repeated? Why the significant difference from for-loops? Better yet, is there some intended strategy for using while-loops in computation-expressions?

• Jquery: Setting permanent height to an specific tab & resize plugin

  - by charlieCodex

  I am working with jquery sliding tabs. I have found a resize plugin that helps the tabs adjust to expanding content. The only thing is that i want to set a permanent height to tab 1(st_content_1). The code i have below works but it is a bit faulty. Should place in the function if statements? Check for the height of the first tab and then set it? Or a any better solution? You can check my EXAMPLE. Jquery $('.st_tab_view').resize(function() { var height = 250 $('div#st_content_1').css('height', height+'px'); var $this = $(this); $this.closest('.st_view').css('height', $this.height()); });

• Drawing Image onto Canvas Stretches Image?

  - by Fred Finkle

  I have this code (stolen from the web): function readIt() { var reader = new FileReader(); reader.onload = (function(e) { var img = new Image(); img.src = e.target.result; var c = document.getElementById("canvas"); var ctx = c.getContext("2d"); ctx.drawImage(img, 0, 0); } ); reader.readAsDataURL(document.getElementById('userImage').files[0]); } Which works up to a point. The canvas's width and height are set to the size of the image, but only the top left of the image appears - It appears to be stretched so it fits all the space allocated to the canvas (enough to display the whole image - 615px x 615px). If I add an <img> element sized the same size as the canvas and point the src to the image in the file system it appears perfect. I'm using Chrome, but it appears the same in Firefox. Thanks in advance.
