• Station ID - more than IP

  - by bensiu

  Hello I am working on internal PHP application where users login only from our network (we are on dedicated IP and application is checking $_SERVER['REMOTE_ADDR'] and if is match our IP go thru if not - Bye However how I can identify from which station user is login ? Using cookie not gonna work - those are windows station working under control MS StedyState and all cookies are deleted every login I don't need nothing fancy like full MAC address just any unique ID (can not be application username - because users use different stations) Any ideas ? Maybe Javascript is able to grab some Unique detail from station's browser (IE 8) and pass this as hidden input? bensiu

• I can't seem to connecting any of my IBOutlets between IB and XCode.

  - by Bonnie

  I created a new iPhone project using the built-in "tab bar" template. I put a few sliders, labels, textfields in the view. I added in needed code for: "IBOutlet, @property, @synthesize, and release" for the above UI objects. It saves and compiles without any errors or warnings. I try to hook-up my connections with control-drag, but don't see any of my IBOutlets appearing in the list. I can't seem to "connect" any outlets from IB to my code. (My IBActions all connect fine) What did I do wrong?

• Site images don't refresh after setting expired headers on .htaccess

  - by Miguel Hernandez

  I have a site that uses a CSS sprite for all the images. I set the .htaccess file to set the expired headers to a future time as they recommend to improve site performance. However, when I updated the sprite image none of my browsers on two different computers seem to fetch the new image. I deleted the .htaccess serveral times but no luck. I am sure this must be easy as pie to fix but right now I am out of options. Here is the code inside my .htaccess file: # CONFIGURE media caching # Header unset ETag FileETag None <FilesMatch "(?i)^.*\.(ico|flv|jpg|jpeg|png|gif|js|css)$"> Header unset Last-Modified Header set Expires "Fri, 21 Dec 2012 00:00:00 GMT" Header set Cache-Control "public, no-transform" </FilesMatch> <IfModule mod_deflate.c> <FilesMatch "\.(js|css)$"> SetOutputFilter DEFLATE </FilesMatch> </IfModule> Thanks!

• How can I detect 'any' ajax request being completed using jQuery?

  - by Brian Scott

  I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

• window.onbeforeunload ajax request problem with Chrome

  - by lang2

  Hello, I have a web page that handles remote control of a machine through Ajax. When user navigate away from the page, I'd like to automatically disconnect from the machine. So here is the code: window.onbeforeunload = function () { bas_disconnect_only(); } The disconnection function simply send a HTTP GET request to a PHP server side script, which does the actual work of disconnecting: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { } ); } This works fine in FireFox. But with Chrome, the ajax request is not sent at all. There is a unacceptable workaround: adding alert to the callback function: function bas_disconnect_only() { var xhr = bas_send_request("req=10", function() { alert("You're been automatically disconnected."); } ); } After adding the alert call, the request would be sent successfully. But as you can see, it's not really a work around at all. Could somebody tell me if this is achievable with Chrome? What I'm doing looks completely legit to me. Thanks,

• Cannot create instance of 'Ribbon'

  - by user354433

  I'm having trouble using the Ribbon control from the Office 2007 RibbonControlsLibrary.dll. It works for most people but not for me. The fault I get is: Cannot create instance of 'Ribbon' defined in assembly 'RibbonControlsLibrary, Version=3.5.31016.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Exception has been thrown by the target of an invocation The problem is probably not with the code since it works for other people. Its the Ribbon class thats causing the problem. If I remove any references to the Ribbon class but keep the references to RibbonWindow I don't get any exceptions. Any help appreciated

• Scriptaculous Slider stops working in iFrame

  - by KcYxA

  Hi there, I am stumped! I have a form for leaving reviews that uses a slider from the Scriptaculous library. The form is retrieved through Ajax once a user clicks on a link to leave a review and all works fine. In order to enable ajax-looking file uploading, I'm using an iFrame to submit the review. My problem occurs when the form is returned due to user input errors. The slider stops working! No Javascript errors. The Control.Slider gets initialized, yet it doesn't work. Any ideas on why this could be happening? Thanks!

• AJAX CascadingDropdown - Setting the selected index

  - by RPM1984

  I have a CascadingDropDown on an ASP.NET page. Now, the prompt text is "Select State". (list of states). However, on a different version of this page (ie querystring), i might want to set the selected index to "California" for example. How can i do this? The web service used by the ajax control (ie GetStates) gets invoked at the same time the jquery document.ready function is triggered (ie asynchronously). So when i try and set the selected index in jquery, the items are not yet bound. Is there a way to attach a handler to the ajax dropdown so that i can set the selected index once the webservice call has completed, and the items are bound?

• Strict pointer aliasing: any solution for a specific problem?

  - by doublep

  I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

• "paste" listener on a SWT widget

  - by Fredrik

  I have an application with a SWT widget, say a org.eclipse.swt.widgets.Text, and want to add some control to the paste function. The idea is that if the user can paste a string of IDs, I detect that, run some code and paste the object that corresponds to the IDs. So I'm looking for some "ClipBoardListener" of some sort to add to my widget, but that doesnt seem to exist. A keylistener would only trap the pastes done by key and then you would have to deal with different key combos for pasting in different OS's. Based on this java 1.2 question I tried subclassing the text class and override the inser method, but that didnt work Exception in thread "main" org.eclipse.swt.SWTException: Subclassing not allowed Seemed like an ugly solution anyway.

• How to implement a Google-chrome-like title bar for Java SWT application

  - by MartyC

  I have inherited development of a Java/SWT application running on Windows only. One of the feature requests that I need to scope is a Google-chrome-type title bar in place of the SWT windows title bar. The application's tabs appear at the same level as the window control buttons. My understanding is that I will need to: write a Windows widget capable of rendering the custom look and managing tabs as opposed to menus. expose the Windows widget as a dll for use in Java via JNI write a custom SWT widget to wrap it and expose the tab management interface. I have a lot of experience with Java programming, GUI programming with Swing/AWT, and non-GUI C# programming. Windows GUI programming and SWT are new to me so I'm not sure where to start. The best I have found so far is a 2001 article on writing your own SWT widget. My biggest unknown is the best way to implement a custom Windows application-window.

• Calling an svn update from a php script via a browser is not working

  - by hbt

  Hey guys, I have two scripts. running an update and calling shell_exec('svn update') and shell_exec('svn st') running a mysqldump shell_exec('mysqldump params') The svn script is not running the update command, the svn st is printing results but not the svn update I tried to declare parameters when calling svn update eg 'svn update ' . dir . ' --username myuser --password mypasswd --non-interactive'; -- still nothing Played with most of the params If this is something related to binaries/permissions/groups, I don't see it. The mysqldump command works fine and is producing a file, so why isn't the svn updating the filesystem? Please do not advise using core SVN classes in PHP. This is not an option, I don't have complete control over the server and the module is not available. Thanks for your help, -hbt PS: important thing to mention here. The scripts works when called via the command line. It only fails when called via a web browser.

• How to adjust video recording brightness?

  - by Paul

  When I record videos in low-light conditions on my Motorola Droid results are poor... very dark images. On my old phone, an LG Dare, recording in low light works better thanks to a brightness adjustment in the video recorder which can be set manually... Android does not have a similar brightness adjustment when recording video. Does anyone have suggestions for how to adjust the brightness using Android's APIs? I have searched the official APIs, but I cannot find a way to control brightness.

• Winform not scrolling when drawing objects on it

  - by dezkev

  Hello All, C#3.0,.net framework 3.5 I am drawing ( using the draw method in the graphics class) a lot of solid rectangles on a windows form vertically. The form starts at 500 x 500 px and the rectangles are only drawn at runtime after data is downloaded from the net -and the number of rectangles depends on the download so I do not know it upfront. So only a few rectangles are drawn as the size of the form is fixed. So I googled/Binged ( lest someone suggest I do that) and found a few tips but they don't work in this case -like setting the forms AutoScroll property to true or trying double buffering.I also tried to draw on a listbox control and set it's scroll property etc...but no dice. I'm guessing there is no way to display , say 200 rectangles vertically on a windows form using draw. I need some other solution... any ideas please. Maybe a list of pictureboxes and then populate each picturebox with the solid color ? Thanks

• Using different versions of jQuery on the same page

  - by nimcap

  Users of my service includes a JS in their pages that I provide. I am hosting the script they are including. My script does some manipulation on their content. I am sick of writing my own DOM manipulators/selectors and wasting hours for jobs that can be done with 1 line of code if I can use jQuery. Some of the users of my service already uses jQuery (or Prototype etc.) on their pages, so if I include jQuery there will be a conflict. Because there will be version differences, I don't want to use their jQuery selectors, methods either in case jQuery exists. Keeping in mind that I have no control over their pages, how can I include jQuery and avoid conflict?

• Adding global blank option to DroDownList in MVC

  - by Diegos Grace

  Is there a way of using a templated helper in mvc so that each and every select list in my project has a custom default 'Choose an option' with null value etc. The posts I have seen seem a little complex, is it possible to have a DropDownList.ascx file in shared view folder with something like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<SelectListItem>>" %> <%= Html.DropDownList(selectlist name, selectlist value, "Choose an option")%> And then having a UIHint("DropDownList") for each dropdownlist in the ViewModel? Some guidance on syntax of parameters would be much appreciated, where name and value of the viewmodel dropdownlist plus the 'Choose an option' string are passed. Or is this all wishful thinking?

• WPF component for 2D tree diagram

  - by pdm2011

  I'm looking for a well-documented, supported WPF component that provides an API for visualisation of 2D tree diagrams. Ideally something easy to use, customisable (i.e. supports various flavours of nodes and splines) and preferably with automated layout control. Tools that look good so far are GoXam (http://www.nwoods.com/components/silverlight-wpf/goxam-overview.htm) and yFiles WPF (http://www.yworks.com/en/products_yfileswpf_about.html). Just wondering if anyone has experience with either of these, or can recommend an alternative? Thanks!

• How to limit number of displayed items in html.dropdownlist?

  - by Remnant

  I have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)? I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?). I am using IE6 and IE7.

• Is there a strategy to back-port C# code?

  - by ianmayo

  Hi all, I intend using the Argotic framework in support of a .Net Atom server. Unfortunately my target server (over which I have no control) only has .Net 1.1 - any the Argotic library is only in .Net 2 and 3.5. So, I now need to back-port the code to 1.1. Can anybody provide any strategic tips for this undertaking? I'm aware of the merits of using Unit Tests to verify the ported code (here). should I be looking for automated tools? should I just import the code into VS2003 .Net 1.1 project and work through the compiler warnings? Any tips appreciated. cheers, Ian

• Memory leak when declaring NSString from ABRecordCopyValue

  - by Ben Thompson

  I am using the following line of code... NSString *clientFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); The 'analyse' feature on Xcode is saying that this giving rise to a potential memory leak. I am not releasing clientFirstName at all as I have neither alloc or retain'd it. However, I am conscious that ABRecordCopyValue may not be returning an object as say a command like [NSMutableArray arrayWithArray:someArray] would which might mean I am indeed creating a new object that I control and must release. Keen to hear thoughts...
