• Jquery: change event not triggered in IE

  - by Kenneth

  Hi, I have some code updating a dropdownlist, and then I fire the "change" event manually. It works like it should in firefox, opera and so on, but not in Internet Explorer. Any idea why? Code attached below. $(".bringFraktvalgRadio").click(function() { var selectedValue = $(".bringFraktvalgRadio:checked").val(); $("#<%= dropDeliveryOption.ClientID %> option[value=" + selectedValue + "]").attr("selected", true); $("#<%= dropDeliveryOption.ClientID %>").trigger("change"); });

• ActionScript Aligning Graphics Line Style Stroke?

  - by TheDarkIn1978

  is it possible to align the stroke of a graphic with actionscript? for example, the following code creates a black rounded rect with a grey stroke that is automatically centre aligned. var t:Sprite = new Sprite(); t.graphics.lineStyle(5, 0x555555); t.graphics.beginFill(0, 1); t.graphics.drawRoundRect(25, 25, 200, 75, 25, 25); t.graphics.endFill(); the lineStyle function doesn't seem to offer any built-in functionality for aligning the stroke. in Adobe Illustrator, you can align a stroke to be either centre (default), inside or outside.

• Java- Copy file to either new file or existing file.

  - by jared

  Hi- I would like to write a function copy(File f1, File f2) f1 is always a file. f2 is either a file or a directory. If f2 is a directory I would like to copy f1 to this directory (the file name should stay the same). If f2 is a file I would like to copy the contents of f1 to the end of the file f2. So for example if F2 has the contents: 2222222222222 And F1 has the contents 1111111111111 And I do copy(f1,f2) then f2 should become 2222222222222 1111111111111 Thanks!

• Extjs 3.4 - Button Icon does not show or does not center

  - by Chris

  I want to fill a button with an icon I created but whatever I have tried just seems to put the icon either half cut off and way left, or it doesn't show at all. I've been trying different combinations of CSS and the icon, iconcls, cls button options. I was following the Ext 3 buttons example page but that doesn't seem to display anything for me... This code is an item inside my form panel (I try to replicate this with different buttons in the panel) { xtype: 'container', layout: { type: 'table', columns: 2, tableAttrs: { cellspacing: 5 } }, // padding: 5, pack: 'center', align: 'middle', items: [{ xtype: 'button', width: 40, // scale: 'medium', ref: '../drawToolsBtn', tooltip: 'Drawing Tools', icon: 'img/draw.png', iconAlign: 'top', baseCls: 'x-plain', // iconCls: 'drawBtn', enableToggle: true, // padding: 3, toggleHandler: function(btn, state) { this.showDrawToolsWin(state); }, scope: this },{ xtype: 'label', // columnWidth: 1, // remainder of container padding: 3, text: 'Click button to open Drawing Tools Menu' }] } CSS -------------------- .drawBtn{ background: url(../img/draw.png) !important; } Thank you for any help!

• How to leave out some statements while executing java code?

  - by iamrohitbanga

  In C++ if we do not want some statements to compile into code that ships like assert function calls, we control their compilation through #ifndef preprocessor directives. How do we do this in Java? I have some System.out.println() statements for debugging which I would like to remove for the final code. one way is to make them execute conditionally under the affect of a boolean variable. Is there a better way of doing this? As I have a java swing application I can turn off the System.out.println statements without affecting the output. What is the method of doing this?

• Count in base 2, 3, 4 etc in Java and output all permutations

  - by tree-hacker

  I want to write a function in Java that takes as input an integer and outputs every possible permutation of numbers up to that integer. For example: f(1) 0 f(2) should output: 00 01 10 11 f(3) should output: 000 001 002 010 011 012 020 021 022 100 .... 220 221 222 That is it should output all 27 permutations of the digits of the numbers 0, 1, 2. f(4) should output 0000 0001 0002 0003 0010 ... 3330 3331 3332 3333 f(4) should output 00000 00001 ... 44443 44444 I have been trying to solve this problem but cannot seem to work out how to do it and keep getting confused by how many loops I need. Does anyone know how to solve this problem? Thanks in advance.

• variable being weirdly deleted

  - by calccrypto

  im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

• What does this error mean when using OpenAL in the iPhone Simulator?

  - by mystify

  I'm getting this in the console, when creating my OpenAL Sources and Buffers: Cannot find executable for CFBundle/CFPlugIn 0xf530d0 </Library/Audio/Plug-Ins/HAL/Hear.plugin> (not loaded) 2010-05-05 17:11:13.934 Testproj[43173:207] Cannot find function pointer HearCFPlugInFactory for factory 5268FAAB-0147-4272-93FD-4D60A2433C1C in CFBundle/CFPlugIn 0xf430d0 </Library/Audio/Plug-Ins/HAL/Hear.plugin> (not loaded) However, the sounds play nicely. I think HAL is not available on the iPhone, it's just on Mac OS X, right? Do you guys also get that error in the simulator when using OpenAL?

• Linq To SQL: Retain list order when using .Contains

  - by rockinthesixstring

  I'm using Lucene.net to build a MyListOfIds As List(Of Integer) which I then pass on to my Linq service. I then search the database as follows Return _EventRepository.Read().Where(Function(e) MyListOfIds.Contains(e.ID)).ToList Now I know that Lucene is already ordering MyListOfIds based on the weight it gave each term. What sucks is that Linq is losing that order in it's SQL search. My Question: How can I retain that sort order when building my Lambda expression? I tried using LINQPad to see how the query is being built, but because I had to declare a variable LINQPad didn't show me the resultant SQL :-( Here's what I tried in LINQPad Dim i As New List(Of Integer) i.Add(1) i.Add(100) i.Add(15) i.Add(3) i.Add(123) Dim r = (From e In Events Where i.Contains(e.ID) Select e) note: my example is in VB.NET, but I don't mind if responses are in C#

• Facebook Error: "The client token cannot be used for this API" - works on DEV and STAGE but not on LIVE app?

  - by Studio Temp

  I've built a notification sending system that sends notifications to all users of our app, using the app access token. This system is currently running on my localhost. When I configure it with the appid and appsecret for my dev and stage environments, it works fine. But when I put in the appid and appsecret of the LIVE app, I get this error: {"message":"The client token cannot be used for this API", "type":"OAuthException", "code":190} So what's different between dev and live? Dev and Stage are in sandbox mode, Live is not. So I tried disabling sandbox mode on Dev/Stage and they continue to function fine. Dev works fine, Stage works fine, Live gives this error. All other code is the same except for the appid, appsecret, and redirect_uri (changing it to match the domain of each environment). I have checked this post, but unfortunately resetting our appsecret on a site with 1,000,000 users is not something we can do at the moment (too much other functionality relies on it).

• How can I clean up this SELECT query?

  - by Cruachan

  I'm running PHP 5 and MySQL 5 on a dedicated server (Ubuntu Server 8.10) with full root access. I'm cleaning up some LAMP code I've inherited and I've a large number of SQL selects with this type of construct: SELECT ... FROM table WHERE LCASE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE( strSomeField, ' ', '-'), ',', ''), '/', '-'), '&', ''), '+', '') ) = $somevalue Ignoring the fact that the database should never have been constructed to require such a select in the first place, and the $somevalue field will need to be parameterised to plug the gaping security hole, what is my best option for fixing the WHERE condition into something less offensive? If I was using MSSQL or Oracle I'd simply put together a user-defined function, but my experience with MySQL is more limited and I've not constructed a UDF with it before, although I'm happy coding C. Update: For all those who've already raised their eyebrows at this in the original code, $somevalue is actually something like $GET['product']—there are a few variations on the theme. In this case the select is pulling the product back from the database by product name—after stripping out characters so it matches what could be previously passed as a URI parameter.

• Dynamic path in new.AjaxRequest with Rails

  - by Robbie

  Hello, I was wondering if there's anyway to get a 'dynamic path' into a .js file through Ruby on Rails. For example, I have the following: new Ajax.Request('/tokens/destroy/' + GRID_ID, {asynchronous:true, evalScripts:true, onComplete:function(request){load('26', 'table1', request.responseText)}, parameters:'token=' + dsrc.id + '&authenticity_token=' + encodeURIComponent(AUTH_TOKEN)}) The main URL is '/tokens/destroy/:id', however on my production server this app runs as a sub folder. So the URL for this ajax call needs to be '/qrpsdrail/tokens/destroy/:id' The URL this is being called from would be /grids/1 or /qrpsdrail/grids/1 I could, of course, do ../../path -- but that seems a bit hackish. It is also dependent on the routing never changing, which at this stage I can't guarantee. I'm just interested in seeing what other solutions there might be to this problem. Thanks in advance :)

• Convert UTC date to actual date and time

  - by evann

  I have a chart of bitcoin prices. I have the correct prices on the Y-axis, but I cannot get the correct time on the X-axis. The time shows up in a UTC format in my console. I am adding price and date to the series each iteration. I need to get the date of that particular result and find the YEAR, MONTH and DAY of that so I can put it in the right format. Any help is appreciated thanks. $.ajax({ url: "/chart/ajax_get_chart", // the URL of the controller action method dataType: "json", type: "GET", success: function (result) { var result = JSON.parse(result); series = []; for (var i = 0; i < result.length; i++) { tempArray = [parseFloat(result[i]['price'])]; tempDate = Date.parse(result[i]['date']); series.push(tempDate); series.push(tempArray); }

• Outlook Macro to Search

  - by Corpa Loom

  What's the best way to automate this function? I want to be able to do this in Outlook 2010, (1)select a specific mail account (2)Key in a folder that I am looking for (3)Then have the macro/program fire off an "*" asterisk (4)Then insert the text that I keyed in step one. I am trying to automate the search for a folder hot-keys that already exist. My problem is that I can't type the folder that I am looking for fast enough and all the search programs that I have used are far too slow. The hot-key search is awesome and super fast, I just can't type the folder that I am looking for fast enough. Can this process be automated? And I can't use this code, it is far too slow: http://www.vboffice.net/sample.html?mnu=2&smp=82&cmd=showitem&lang=en

• parsing through html with php

  - by salmane

  while working on facebook connect I have to retrieve an access token from a url ( it is not in the url itself but in the file lined to that url) so this is what I do $url = "https://graph.facebook.com/oauth/access_token?client_id=".$facebook_app_id."&redirect_uri=http://www.example.com/facebook/oauth/&client_secret=".$facebook_secret."&code=".$code;" function get_string_between($string, $start, $end){ $string = " ".$string; $ini = strpos($string,$start); if ($ini == 0) return ""; $ini += strlen($start); $len = strpos($string,$end,$ini) - $ini; return substr($string,$ini,$len); } $access_token = get_string_between(file_get_contents($url), "access_token=", "&expires="); it looks ugly and clumsy is there a better way to do it ? thank you .

• How to correctly hook and return GetDlgItemTextA from C++ to C# to C++ from EasyHook

  - by Gbps

  I'm using EasyHook, a C# library for injecting and detouring functions from unmanaged applications. I'm trying to hook onto GetDlgItemTextA, which takes the arguments: UINT WINAPI GetDlgItemText( __in HWND hDlg, __in int nIDDlgItem, __out LPTSTR lpString, __in int nMaxCount );` In my hook, I am casting it as: [DllImport("user32.dll", // CharSet = CharSet.Unicode, SetLastError = true, CallingConvention = CallingConvention.StdCall)] static extern uint GetDlgItemTextA(IntPtr hWin, int nIDDlgItem, StringBuilder text, int MaxCount); And my hook is: static uint DGetDlgItemText_Hooked(IntPtr hWin, int nIDDlgItem, StringBuilder text, int MaxCount) { // call original API... uint ret = GetDlgItemTextA(hWin, nIDDlgItem, text, MaxCount); MessageBox.Show(text.ToString()); return ret; } Unfortunately, the moment this is called, the hooked application crashes. Is there a better cast I can use to successfully hook onto this function? Thanks! I've compiled, editted, and confirmed the working condition of my EasyHook setup. This is just casing and hooking only.

• Setting a Global Doctype

  - by Batfan

  Is it possible using PHP (I was thinking may the phpinfo file or a php.ini file) or an .htaccess file to set a doctype for an entire subdirectory? Basically, in a nutshell, I'm using a software that uses XSL templates to output data to a set of HTML files. Modifying the xsl:output tag to include the doctype breaks the template and therefore, does not work. Just adding the doctype in the XSL file, breaks it as well. I need the proper doctypes in place for my CSS to function properly, cross-browser. I realize that I could add the doctype to the HTML files after export but, I'm really striving to automate this process. Any thoughts?

• C#+Mysql Runs out of Connections. I am using 'using' and closing all connections immediately.

  - by Cyril Gupta

  In the application that I am making right now, I am getting this error: error connecting: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. Evidently I am touching max-count in the connection pool. I am dutifully using 'using' with all connection objects and freeing them up immediately when the function is done with them. This is on C#, and I am using the MySql Data Dll. Is there something wrong with the dotnet connector for MySql? Is there a workaround?

• Accessing a variable passed by jquery using php

  How does php access a variable passed by JQuery? I have the following code: $.post("getLatLong.php", { latitude: 500000}, function(data){ alert("Data Loaded: " + data); }); but I don't understand how to access this value using php. I've tried $userLat=$_GET["latitude"]; and $userLat=$_GET[latitude]; and then I try to print out the value (to check that it worked) using: echo $userLat; but it does not return anything. I can't figure out how to access what is being passed to it.

After this there will be sorted on the amount of products (field count) in the array. Means I have to show sort array first on the basis of img then count. I am using usort( $childLinkCats, 'sortempty' );` function sortempty( $a, $b ) { return empty( $a['img'] ); } it will show array with image value above the one who contains null value. and to sort through count Im using usort($childLinkCats, "_sortByCount"); function _sortByCount($a, $b) { return strnatcmp($a['count'], $b['count']); } It will short by count But I am facing problem that only 1 working is working at a time, but I have to use both, please help me.

• Where is the best place to put <script> tags in HTML markup?

  - by mipadi

  When embedding JavaScript in an HTML document, where is the best place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). This seems to leave the end of the <body> section as a logical place for <script> tags. So, where is the best place to put the <script> tags? (This question references this question, in which it was suggested that JavaScript function calls should be moved from <a> tags to <script> tags. I'm specifically using JQuery, but more general answers are also appropriate.)
