• z-index problem in IE6

  - by simonkagwe

  I have been struggling with a z-index problem in IE6 for quite some time now. I require part of the 'header' portion in my website to open up (using jQuery), and cover a portion of the 'content' section which comes after it. The thing works like a charm on all the browsers I've tested it on (Firefox, Chrome, Opera), but IE6 instead pushes down the content section, which is not what I want. The website itself is here I have done extensive research both here on SO and thro Google but all the workarounds I've found don't work for my case. Please help.

• Can I add an additional eula/tos inside my app on top of the iphone app store agreement

  - by nickthedude

  I have an app that allows users to generate and publish content. I would like to possibly be able to use the content they publish/create to make derivative works, ie books etc (similar to what icanhazcheeseburger has done.) If I were to put an opt in alert to ask the user whether or not they would like to be a part of this, would this violate the iphone sdk? I know this is not programming question so I'm not sure if this is a fair question, but I thought I heard something like you can't add a eula you have to abide by whatever apple dictates in their app store agreement. Also if you have suggestions on different ways to approach getting users to agree to this I'm all ears, but yes that is kind of subjective. Thanks folks, Nick

• CMS for Blog site

  - by Yau Leung

  I would like to create a blog site with features like Engadget. The editor can upload blog and albums while users can comment. I know it's even easier to use blogspot but it's blocked in China. I have tried Joomla before. It seems a bit slow even after removing most of the modules and the memcache plugin doesn't help much either. Is there any other option? Do I need other plugins to run WordPress as blog?

• Using custom scrollbar on jquery lightbox

  - by Bhupi

  Hi, I need to use a custom scrollbar on jquery lightbox. My requirement is that when user clicks on a link then a popup appears and the popup contains 2 or 3 tabs, user can click on any tab to see it's content. In one of those tabs I need scrollbar to show huge content but the scrollbar should not be default it should be custom with any color. Currently I am using "JQuery's JScrollPane" plugin http://jscrollpane.kelvinluck.com to achieve the functionality, but this is not working on IE 6,7 and 8, mean scrollbar does not appear on IE. It works fine on Firefox and Chrome. Note: the same plugin works fine on IE also when I use it on page's element which is available while page load but not while the element is shown dynamically on lightbox. Thanks

• How to use the new VS 2010 configuration transforms and apply them to other .config files?

  - by Wallace

  I have setup some configuration transforms in my web.config for my connectionStrings, etc. But I have separated out some areas of my web.config into separate files, ex) appSettings.config. How can I configure Visual Studio and MSBuild to perform config transformations on these additional config files? I have already followed the approach of the web.config to relate the files together within my web application project file, but transformations are not automatically applied. <ItemGroup> <Content Include="appSettings.Debug.config"> <DependentUpon>appSettings.config</DependentUpon> </Content> </ItemGroup>

• Using Typeface.js within a GWT app

  - by dindeman

  I am looking for some sample Java code demonstrating how to get AJAX content displayed into a custom font using Typeface.js within a GWT app. I have tried a little bit by calling the following native function native void Typeface_renderDocument() /*-{ $wnd._typeface_js.renderDocument(); }-*/; after having filled the relevant widget with the AJAX content, and after calling the following function on the widget : void applyTypeface(Widget widget) { widget.addStyleName("typeface-js"); widget.getElement().getStyle().setProperty("fontFamily", "Helvetiker"); Typeface_renderDocument(); } ...where Helvetiker is a custom font (actually available from Typeface.js fonts page (http://typeface.neocracy.org/fonts.html). But that didn't work. I am looking forward to any suggestions since I am bit stuck here. Alternatively I would be interested in an example using cufón within GWT, although I am not so keen about the replacement by images that cufón does (which is the main reason why I was trying to use Typeface.js.)

• in app purchases question

  - by bdt

  I am looking into the iPhone in app purchased models and need to implement a subscription. Ex content will be available for 24 hours. Now the most important thing is that it needs to be available on all the other devices, so bought on the iPhone, viewable on the iPad. I'm not sure how this works ? I need to store some information on the developer server but is this the transaction id and current date/time so when launching the app on the iPad, you will attempt to buy the content again. Apple will see that this user already bought that and hopefully returns the transaction ID. At that moment I can verify if the time limit it still valid or not. Can anyone confirm this method off working? If this is correct is there a 'renew'?

• JavaFX - question regarding binding button's disabled state

  - by jamiebarrow

  I'm trying to create a dummy application that maintains a list of tasks. For now, all I'm trying to do is add to the list. I enter a task name in a text box, click on the add task button, and expect the list to be updated with the new item and the task name input to be cleared. I only want to be able to add tasks if the task name is not empty. The below code is my implementation, but I have a question regarding the binding. I'm binding the textbox's text variable to a string in my view model, and the button's disable variable to a boolean in my view model. I have a trigger to update the disabled state when the task name changes. When the binding of the task name happens the boolean is updated accordingly, but the button still appears disabled. But then when I mouse over the button, it becomes enabled. I believe this is due to JavaFX 1.3's binding being lazy - only updates the bound variable when it is read. Also, when I've added the task, I clear the task name in the model, but the textbox's text doesn't change - even though I'm using bind with inverse. Is there a way to make the textbox's text and the button's disabled state update automatically via the binding as I was expecting? Thanks, James AddTaskViewModel.fx: package jamiebarrow; import java.lang.System; public class AddTaskViewModel { function logChange(prop:String,oldValue,newValue):Void { println("{System.currentTimeMillis()} : {prop} [{oldValue}] to [{newValue}] "); } public var newTaskName: String on replace old { logChange("newTaskName",old,newTaskName); isAddTaskDisabled = (newTaskName == null or newTaskName.trim().length() == 0); }; public var isAddTaskDisabled: Boolean on replace old { logChange("isAddTaskDisabled",old,isAddTaskDisabled); }; public var taskItems = [] on replace old { logChange("taskItems",old,taskItems); }; public function addTask() { insert newTaskName into taskItems; newTaskName = ""; } } Main.fx: package jamiebarrow; import javafx.scene.control.Button; import javafx.scene.control.TextBox; import javafx.scene.control.ListView; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.scene.layout.HBox; def viewModel = AddTaskViewModel{}; var txtName: TextBox = TextBox { text: bind viewModel.newTaskName with inverse onKeyTyped: onKeyTyped }; function onKeyTyped(event): Void { txtName.commit(); // ensures model is updated cmdAddTask.disable = viewModel.isAddTaskDisabled;// the binding only occurs lazily, so this is needed } var cmdAddTask = Button { text: "Add" disable: bind viewModel.isAddTaskDisabled with inverse action: onAddTask }; function onAddTask(): Void { viewModel.addTask(); } var lstTasks = ListView { items: bind viewModel.taskItems with inverse }; Stage { scene: Scene { content: [ VBox { content: [ HBox { content: [ txtName, cmdAddTask ] }, lstTasks ] } ] } }

• Tabbed javascript widget for a Rails app

  - by neilc

  A user registers on our Rails app and they're given javascript to embed a widget in their website. The widget has a tabbed interface, like the JQuery tabs http://stilbuero.de/jquery/tabs_3/. iFrames have been tested, but the widget form factor and cross-domain policy negates the use of iframes. The widget is very dynamic and will often update the DOM with new content - and because of cross-domain policy, it looks as though JSONP is necessary. I understand that 'widget.js.erb' needs to create the widget layout, reference a stylesheet, render the tabs, etc - but once a tab is clicked, how does the widget request the content from the Rails app and render it in the DOM?

• Lightning whip particle effects

  - by Fibericon

  I'm currently using Mercury Particle Engine for the particle effects in my game, and I'm trying to create a sort of lightning whip - basically a lightning effect bound to a line that curves when the player moves. I know how to use the editor, and I have particle effects working in game. However, I'm completely lost as to where I should start for this specific particle effect. Perhaps if I could find the code for it in a different particle engine, I could convert it, but I can't seem to find that either. What I did find was a lot of tutorials for creating the lines associated with lightning programmatically, which doesn't help in this case because I don't want it to be rigid. Perhaps it would be more like some sort of laser beam with crackling effects around it? I'm running into a wall as far as even beginning to implement this goes.

• Easiest, most fun way to program 2D games? Flash? XNA? Some other engine?

  - by Maxi

  Hi, this is a post detailing my search for the most enjoyable way for a hobbyist game programmer to sweeten his free time with making a game. My requirements: I looked at Flash first, I made a couple of small games but I'm doubtful of the performance. I would like to make a fairly large strategy game, with several hundred units fighting simultaneously, explosions and animations included. Also zoomable maps. I saw that Adobe has a new 3D API for Flash, but I don't know if that improves 2D performance aswell, I couldn't find anything related to that question on their MAX10 sessions. Would you say that Flash is a good technology for making large 2D games easily? I really like Actionscript, and I love how easy everything is in Flash. There are several engines available which make it even easier. I just do this for fun, and it would be even better if there were proper animation/particle editors available and if the engine I were to use, would be available for multiple platforms. (so more people can play my game once finished). I'd like to have it available on many mobile platforms aswell. (because I love touch input for some reason) I do know the XNA framework pretty well, but there are no good engines available for it, and it will only run on Windows, which is a huge turn off. Even bigger is, that you need to install the XNA redistributable each time you want to give the game to someone. If I use XNA, I would have to make all the tools myself, and I'd probably have to make them with WPF. (I'd love to make tools with Adobe AIR, but unfortunately the API's for image manipulation etc. are far worse in Flash, than they are in XNA/WPF.) Now, I'm aware that I could make my own engine that supports each of those platforms, but quite frankly, that would be too much work plowing through APIs. After all, I want to make a game, not an engine. So the question becomes: Is there maybe a cross platform (free or free to develop?) engine available that I could use for 2D development? I prefer: C#, Actionscript. I don't mind using c++ if the toolset is above average, but I highly doubt that there is something out there like that. Please prove me wrong :) So summary: I'd like to use Flash, but I don't know if it scales well enough. I'm not a scripter, I want some real APIs that I can work with inside a proper IDE. Just for information, I looked at several alternatives, I'm actually looking for a long time already. You'd help me a lot to make a decision finally. Feature-wise the Flatredball engine would be ideal. But I tried their tools, and quite frankly, they are horrible. Absolutely unusable, I'd need to make my own for sure. I didn't look at their API, but if their tools are so bad, I'm not inclined to look further. Unity3D. This one is quite nice, but I really don't need 3D, and it is quite ...a lot of work to learn. I also don't like that it is so expensive to use for different platforms and that I can only code for it through scripting. You have to buy each platform separately. The editor usability is average, the product overall is good enough for most purposes, but learning it myself would be overkill. Shiva 3D. It looks good enough, but again: I don't really need 3D. The editor usability is a little worse than Unity3D in my opinion and it wasn't clear to me how to start programming. I think it requires C++ for coding, so that's a negative too. I want to have fun, and c# is fun ;) SDL. Quite frankly, I'd still need to port to all those different SDL implementations. And I don't like OpenGL style programming, it's just plain ugly. And it needs c++, I know that there might be some wrappers available, but I don't like to use wrappers, because... Irrlicht. A lot of features, but support seems to be low and it is aimed at enthusiasts. C# bindings get dropped repeatedly. I'm not an engine enthusiast, I just want to make a game. I don't see this happening with Irrlicht. Ogre3D. Way too much work, it's just a graphics engine. Also no multiple platform support and c++. Torque2D. Costs something to use, and I didn't hear a lot of good things about support and documentation. Also costs extra for each platform.

• How i can sign and/or group a specific set of vertices in a 3D file container like OBJ ? - in Blender

  - by user827992

  I would like to export a 3D model with each part having a name or a label if you will. For example i would like to export a model of an human body and name each part in specifics vertex groups like: left hand, right hand, right foot, head, ears, ... and you got the idea; so i can have a single 3D model that i can explode in various parts if needed. If there is a better technique about how to mark vertex groups in a 3D file please share your solution. As 3D editor i use Blender.

• Why are $_POST variables getting escaped in PHP?

  - by George Edison

  When my PHP script receives data from an AJAX POST request, the $_POST variables are escaped. The really strange thing is that this only happens on my production server (running PHP 5.2.12 on Linux) and not on my local server (running PHP 5.3.1 on Windows). Here is the AJAX code: var pageRequest = false; if(window.XMLHttpRequest) pageRequest = new XMLHttpRequest(); else if(window.ActiveXObject) pageRequest = new ActiveXObject("Microsoft.XMLHTTP"); pageRequest.onreadystatechange = function() { } var q_str = 'data=' + " ' "; pageRequest.open('POST','unnamed_page.php',true); pageRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); pageRequest.setRequestHeader("Content-length", q_str.length); pageRequest.setRequestHeader("Connection", "close"); pageRequest.send(q_str); Is there any reason this is happening? And how should I fix this so that it works on both servers?

• How to create column width in CSS that expands with large images yet stays a default size for normal

  - by ChrisJF

  I am creating an HTML5 web page with a one column layout. Basically, it is a forum thread with individual posts. I have specified in my CSS file the column to be 600px wide and centered it in the window using margin: 0 auto;. However, some images that are in the individual posts are larger than 600px and spill out of the column. I'd like to widen an individual post to fit the larger images. However, I want all the other posts to still be 600px wide. Right now, I'm just using overflow:auto which will create a scroll bar, but this is less than ideal. Is this possible to have the an individual post width grow for larger content yet stay fixed for normal content? Is this possible using just pure CSS? Thanks in advance!

• How to replace a div container with javascript

  - by Kovu

  Hi, I must have a little design in javascript. I have a menu with 5 entrys and only 1 HTML-page. So I will have a content-div and enabled and disabled different static content in it, each menu-entry is another content. I tried with 5 divs and disable 4 of them and enable 1, but the element under each other means every div is like a - enabled or not, so the "content" is moving then. Hope its understandable. Here is the code so far: <html><head><title>Des Einsame-Katerchen's kleine Homepage</title> <style type="text/css"> a:link { font-weight:bold; color:blue; text-decoration:none; } a:visited { font-weight:bold; color:blue; text-decoration:none; } a:focus { font-weight:bold; color:blue; text-decoration:none; } a:hover { font-weight:bold; color:blue; text-decoration:line-through; } a:active { font-weight:bold; color:blue; text-decoration:none; } h1:focus { background-color:red; } h1:hover { background-color:silver; } h1:active { background-color:green; } </style> <script> function an(id) { document.getElementById('start').style.visibility = 'hidden'; document.getElementById('start').style.height = '0px'; document.getElementById('me').style.visibility = 'hidden'; document.getElementById('me').style.height = '0px'; document.getElementById('rpg').style.visibility = 'hidden'; document.getElementById('rpg').style.height = '0px'; document.getElementById('musik').style.visibility = 'hidden'; document.getElementById('musik').style.height = '0px'; document.getElementById('screens').style.visibility = 'hidden'; document.getElementById('screens').style.height = '0px'; document.getElementById(id).style.visibility = 'visible'; document.getElementById(id).style.height = '500px'; } </script> </head> <body style=" " > <div style="width=100%; text-align:center; border: 1px red solid; height:40px;"> <div style="float:left; width:100px;"><a href="#" OnClick="an('start')" >Startseite</a></div> <div style="float:left; width:100px;"><a href="#" OnClick="an('me')" >Über mich</a></div> <div style="float:left; width:100px;"><a href="#" OnClick="an('rpg')" >RPG-Chars</a></div> <div style="float:left; width:100px;"><a href="#" OnClick="an('musik')" >Musik</a></div> <div style="float:left; width:150px;"><a href="#" OnClick="an('screens')" >Knuddels-Screens</a></div> </div> <br> <div id="start" style="border:1px red solid; width:500px; height:500px; overflow: visible; " > a </div> <div id="me" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " > b </div> <div id="rpg" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " > c </div> <div id="musik" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " > d </div> <div id="screens" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " > e </div> </body>

• How do I fire an asynchronous call in asp classic and ignore the response?

  - by Hexate

  Here's the gist: I have a call I want to make in asp, and I do not care about the response. I just want to fire the call and I do not want the page to wait for the response. According to the documentation, it should look something like this: dim xmlhttp : set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP") xmlhttp.Open "POST", url, true '' setting the 'asynchronous' option to 'true' xmlhttp.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8" xmlhttp.setRequestHeader "Content-Length", Len(XMLData) xmlhttp.send XMLData This works peachy when calling synchronously, but when I flip the ansynchronous option to 'true', nothing fires. What I can gather from the internet is that users do something like the following: While xmlhttp.readyState <> 4 xmlhttp.waitForResponse 1000 Wend Am I crazy in that this does not really seem like an asynchrous call anymore though if you are waiting for a response? putting the line xmlhttp.waitForResponse 1 right after the send will cause the request to fire, but again, I don't want to wait a second. Any thoughts?

• Unset/Change Binding in WPF

  - by captcalamares

  How can I unset the binding applied to an object so that I can apply another binding to it from a different location? Suppose I have two data templates binded to the same object reference. Data Template #1 is the default template to be loaded. I try to bind a button command to a Function1 from my DataContext class: <Button Content="Button 1" CommandParameter="{Binding }" Command="{Binding DataContext.Function1, RelativeSource={RelativeSource AncestorType={x:Type Window}}}"/> This actually works and the function gets binded. However, when I try to load Data Template # 2 to the same object (while trying to bind another button command to a different function (Function2) from my DataContext class): <Button Content="Button 2" CommandParameter="{Binding }" Command="{Binding DataContext.Function2, RelativeSource={RelativeSource AncestorType={x:Type Window}}}" /> It doesn't work and the first binding is still the one executed. Is there a workaround to this? EDIT (for better problem context): I defined my templates in my Window.Resources: <Window.Resources> <DataTemplate DataType="{x:Type local:ViewModel1}"> <local:View1 /> </DataTemplate> <DataTemplate DataType="{x:Type local:ViewModel2}"> <local:View2 /> </DataTemplate> </Window.Resources> The View1.xaml and the View2.xaml contain the button definitions that I described above (I want them to command the control of my process flow). ViewModel1 and ViewModel2 are my ViewModels that implement the interface IPageViewModel which is the type of my variable CurrentPageViewModel. In my XAML, I binded ContentControl to the variable CurrentPageViewModel: <ContentControl Content="{Binding CurrentPageViewModel}" HorizontalAlignment="Center"/> In my .CS, I have a list defined as List<IPageViewModel> PageViewModels, which I use to contain the instances of my two View Models: PageViewModels.Add(new ViewModel1()); PageViewModels.Add(new ViewModel2()); // Set starting page CurrentPageViewModel = PageViewModels[0]; When I try to change my CurrentPageViewModel to the other view model, this is when I want the new binding to work. Unfortunately, it doesn't. Am I doing things the right way?
