  • IE JavaScript Mystery

    - by William Calleja
    I have the following JavaScript function function headerBanner(){ var current = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'none'); if(bannerIndex== $('.bannerImages img').size()){ bannerIndex= 1; }else{ bannerIndex= (bannerIndex*1)+1; } var next = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'block'); } In every browser on the planet, with the exception of IE (8, 7 or less), the above code is working correctly. In Internet Explorer it's going through it and having no effect. I've put alerts at every line of the function and they all fire, even in IE, but the banner simply doesn't change. Is there any reason as to why this is so?

  • Saving WPF WIndow and Position

    - by moogs
    What would be the best way to save the window position and size in a WPF app? Currently, I'm saving the window size and position of a WPF App. Here are the events I handle: SourceInitialized : The saved info is loaded on to the window WindowClosing : The current info is saved to the backing store (I copied this from an example). The problem is, when the window is minimized and restored, the settings from the last WindowClosing is retrieved. Now, the StateChanged event fire AFTER the window has minimized, so it does not seem to be what i need. Thanks

  • use java-ffmpeg wrapper, or simply use java runtime to execute ffmpeg?

    - by user156153
    I'm pretty new to Java, need to write a program that listen to video conversion instructions and convert the video once an new instruction arrives (instructions is stored in Amazon SQS, but it's irrelevant to my question) I'm facing a choice, either use Java RunTime to exec 'ffmpeg' conversion (like from command line), or I can use a ffmpeg wrapper written inJava http://fmj-sf.net/ffmpeg-java/getting%5Fstarted.php I'd much prefer using Java Runtime to exec ffmpeg directly, and avoid using java-ffmpeg wrapper as I have to learn the library. so my question is are there any benefits using java-ffmpeg wrapper over exec ffmpeg directly using Runtime? I don't need ffmpeg to play videos, just convert videos Thanks

  • Will a Response.Redirect exception go to global.asax?

    - by mgmedick
    I'm aware that when you call Response.Redirect it fires a ThreadAbortException. A co-worker has demonstrated calling response.redirect and then it goes to the global.asax. For the life of me I cannot get the ThreadAbortException to go to the global.asax, its like it is being suppressed naturally in the system. The reason I'm asking this is we believe the response.redirect is the cause of some automated error emails, but I'm not convinced this is the case especially if I can't even get it to debug into the global.asax. Any Ideas why I can't get the Response.Redirect to fire the global error handler?

  • How do I build a specialized JQuery Timer

    - by Sayem Ahmed
    I have an asp.net page where two grid views are available showing current stock market price updates. I need to update these two grid views every 20 seconds. So I was thinking of using JQuery to do this job. What I need is a timer which will fire every 20 seconds, send an ajax request to the servers, bring the order lists from the server using json and then update those two grid views. If a request to the server is still being served 20 seconds after it is fired, then I want the old one to be aborted without causing any trouble. I already know how to bring objects using json. I just need to figure out how to send a request every 20 seconds and cancel a request if it is still being server for 20 seconds.

  • use boolean with visible, as3

    - by VideoDnd
    Is there a better way to do use a use a boolean with visible? This animation blinks 30 times and stops. It works without error, but takes a moment to load. I would like to learn other ways of using visibility with conditionals. var timz:Timer = new Timer(100,30); timz.addEventListener(TimerEvent.TIMER, doIt); var condition:Number = 5; function doIt(event:TimerEvent):void{ trace("fire!"); if(condition=5){ box.visible = !box.visible; } } timz.start();

  • JQuery delegate what may cause it to not function

    - by Jafin
    I have a webpage using jquery 1.42 The following 2 segments of code live in my page. $('body').delegate('h2', 'click', function() { $(this).after("<p>delegate paragraph!<\/p>"); }); $('body h2').live('click', function() { $(this).after("<p>live paragraph!<\/p>"); }); The live method always works, yet the delegate doesn't fire at all. If I create a trivial page with simple html <body><h2>blah</h2></body> both approaches work. So I'm assuming there is something else going on in my page. With firebug I am seeing no javascript errors, no html errors. and breakpoints on the delegate method definately do not get hit. What else might be the cause of delegate not triggering?

  • How do I handle editing of custom types in a C# datagridview?

    - by Ian Hopkinson
    I have a datagridview in which one column contains a custom class, which I have set using: dgvPeriods.Columns[1].ValueType = typeof(ExDateTime); It is rigged up to display correctly by handling the CellFormatting event, but I'm unsure what event to handle for cell editing. In the absence of doing anything I get a FormatException as the datagridview tries to convert String to ExDateTime as I try to move focus out of the edited cell. I tried adding type conversion to my ExDateTime custom class: public static implicit operator ExDateTime(string b) { return new ExDateTime(b); } But this this didn't work. I also tried handling the DataError event, but this seems to fire too late. The datagridview is not databound.

  • Problem with events and ParseControl

    - by Richard Edwards
    I'm adding a control (linkbutton) dynamically using ParseControl and it's fine except when I specify an event handler. If I use: Dim c As Control = ParseControl("<asp:LinkButton id=""btnHide"" runat=""server"" text=""Hide"" OnClick="btnHide_Click" />") it correctly adds the control to the page but the click event doesn't fire. If instead I find the control in the controls collection and manually wire up the event it works fine. I've tried loading in both Page_Init and Page_Load and it's the same thing either way. Any ideas?

  • How to do concurrent modification testing for grails application

    - by werner5471
    I'd like to run tests that simulate users modifying certain data at the same time for a grails application. Are there any plug-ins / tools / mechanisms I can use to do this efficiently? They don't have to be grails specific. It should be possible to fire multiple actions in parallel. I'd prefer to run the tests on functional level (so far I'm using Selenium for other tests) to see the results from the user perspective. Of course this can be done in addition to integration testing if you'd recommend to run concurrent modification tests on integration level as well.

  • Where can I find boost::fusion articles, examples, guides, tutorials?

    - by Kyle
    I am going to go ahead and shamelessly duplicate this question because the accepted answer is essentially "nope, no guides" and it's been nearly a year now since it's been asked. Does anyone know of any useful articles, guides, tutorials, etc. for boost::fusion besides the barebones documentation on boost.org? (which I'm sure is great as a reference after one has learned the library.) I'm completely open to, say, a link to a book on Amazon. Searched for it myself just now but all I came up with was green tea. The top links on Google aren't much better.

  • iPhone: Cocos2d how to make a sequence

    - by Johannes Jensen
    I have two logos, which I want to come in after each other. I'd like to use CCFadeIn and CCFadeOut. I have Logo1, and then I want it to CCFadeIn, then I want it to stay for 2 seconds, then make it fade out using CCFadeOut, and then make Logo2 CCFadeIn for 1 second, stay for 2 seconds and then go away during 1 second with CCFadeOut. How I would make this I'm not completely sure. I can't seem to find a way to make a CCAction fire a method (let's say -finishedFadingInLogo1:), so I don't know how to do this. Any ideas?

  • HTML Link and Jquery Live Only Works on First Try with one click

    - by Jon
    Hi Everyone, I'm running into a problem with jquery live event binding on a link. When the link is added to the page it works fine, however when another link is added to the unordered list it requires two clicks for the click event to fire on either link. Any ideas? $("div#website-messages ul li a").live("click", function() { var link = $(this); changeTab(link.attr("href")); $(link.attr("title")).focus(); return false; });

  • IE 8 specifying background-color changes element behavior

    - by Mateo
    I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.

  • What is the current standard for authenticating Http requests (REST, Xml over Http)?

    - by CodeToGlory
    The standard should solve the following Authentication challenges like- Replay attacks Man in the Middle Plaintext attacks Dictionary attacks Brute force attacks Spoofing by counterfeit servers I have already looked at Amazon Web Services and that is one possibility. More importantly there seems to be two most common approaches: Use apiKey which is encoded in a similar fashion like AWS but is a post parameter to a request Use Http AuthenticationHeader and use a similar signature like AWS. Signature is typically obtained by signing a date stamp with an encrypted shared secret. This signature is therefore passed either as an apiKey or in the Http AuthenticationHeader. I would like to know weigh both the options from the community, who may have used one or more and would also like to explore other options that I am not considering. I would also use HTTPS to secure my services.

  • Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

    - by nganju
    I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

  • Determine when a NSOpenPanel will close

    - by Martin
    I'm trying to determine when an NSOpenPanel is closing before it actually closes. I need to do this so I can overlay another window with a screenshot of the open panel on top of it to be animated. Unfortunately, all the notifications that you seem to be able to access seem to fire AFTER the window's already been closed. This leads to a jarring stutter before you start your transition. I've tried: - using NSWindow delegate methods on the open panel (apparently, none of the NSWindow delegate methods work) - monitoring panel:userEnteredFilename:confirmed: (not called) - showing the dialog with a callback (callback happens AFTER the panel disappears)

  • how do I notify child controls of a change in the parent

    - by fishhead
    what is the best way to keep a child control up to date for changes in the parent. I have a number of child controls hosted inside my parent object and I can think of two ways to send change information to them. 1) wire the child control to an event in the parent. and fire that event on a change in the parent 2) keep a list of the children in an array and intenerate through the array when the change has happened and invoke a method in the child to handle the new changes. I hope I describe it okay. both work but there is probably a right way to handle this and a wrong way.

  • Quality Design for Asynchronous WCF Services Calls in a Middle-Tier and Returning Data to UI Tier

    - by Perplexed
    I have a WPF application with a group of asynchronous WCF service calls all mashed into the code behind, complete with event handlers and everything, that I have to refactor to productionize and maintain. I want to separate concerns here for maintainability and all the other good reasons to do this, but I'm not sure exactly how to achieve this. Anybody have any good ideas on how to do this, or at least some links to put me in the right direction? My thinking: Create an "infrastructure" layer and reference the services there. Move the asynchronous event handlers into this layer. When an update is called, I will bubble up my own event with my own derivation of the EventArgs class that contains the data the UI will need. I'll have a fairly coupled hooking of the UI to the infrastructure layer as it will consume events I fire off upon completion of an asynchronous data call.

  • Simple network gaming, client-server architecture planning.

    - by michal
    Hi, I'm coding simple game which I plan to make multiplayer (over the network) as my university project. I'm considering two scenarios for client-server communication: The physics (they're trivial! I should call it "collision tests" in fact :) ) are processed on server machine only. Therefore the communication looks like Client1->Server: Pressed "UP" Server->Clients: here you go, Client1 position is now [X,Y] Client2->Server: Pressed "fire" Server->Clients: Client1 hit Client2, make Client2 disappear! server receives the event and broadcasts it to all the other clients. Client1->Server: Pressed "UP" Server->Clients: Client1 pressed "UP", recalculate his position!! [Client1 receives this one as well!] Which one is better? Or maybe none of them? :)

  • How to execute a large PHP Script ?

    - by atif089
    Well basically I may want to execute a script that may take as much as 1 hours as well. What I really want to do is Send SMS to my users using a third party API. So its basically like I supply my script with an array of phone numbers and fire the method to send SMS. However assuming it take 5 seconds to send 1 SMS and I want to send 1000 SMS which is roughly 1 - 2 hours. I can use set_time_limit() because I am on shared host. One way to do this is store numbers in a session and execute each SMS and use javascript to refresh that page until end. This way I need to keep my browser open and the execution will stop if my Internet Connection is disconnected. So, Is there any better way to do this ? Hope I am clear enough to explain what I want? I want to execute a large script that may take hours to execute without getting timeout.

  • ant cpptask with ivy

    - by AC
    A company I am working for, has some c binaries build with ant using cpptask. They use ivy to retrieve shared c libraries every time we start a build which wastes a significant amount of time comparing the revisions and downloading, when then only need to be download if the header files have changed. I have added a target which sets a var, which causes the build to skip over the ivy steps but I'd like a better solution. I see that cpptask creates a file history.xml and only rebuilds to binary if any of the sources have change. I'd like to know if there is way to independently test if the binary needs to build, and it does, I'd like it fire off the ivy targets. I'd also like for a variable to be set if the binary was rebuilt so that I can conditionally start an rpm generation task

  • How do I get a visual debugger on Mac OS when I have no XCode project?

    - by sludge
    I am porting a project over to OS X. I am finding GDB debugging in the console to be woefully insufficient and really need a visual debugger. My project is built using Scons and as such, it sidesteps Xcode's IDE entirely. This is acceptable until I need to fire up a visual debugger and step through my code. Aside from generating and maintaining an Xcode project (to supplement all of the other platforms I have to support already), what can I do to get a visual debugger up and running on OS X? This is for a C++ project.
