  • jQuery .get()/.post() doesn't send an updated cookie

    - by Markus
    Hello, I'am doing something like this: function setCookie(name, value, expire) { var exdate = new Date(); exdate.setDate(exdate.getDate()+expire); document.cookie=name+ "=" +escape(value)+((expire==null) ? "" : ";expires="+exdate.toGMTString()); } // When I click a button // Update the cookie setCookie("test", "1"); function getContent() { // Get the data of our new URL $.get("index.php", loadContent); } function loadContent(data) { // alert the new title // the PHP script is changing title after what cookie-value you have alert($("title", data).text()) } First of all, when Iam alerting it is still the last showing up. So I guess it doesn't send the changed cookies at all.. And for some reason I don't see the request in my Live HTTP Headers window... But also, if i request the URL(without the ajax) it works just fine What am I doing wrong here? Regards Markus

  • ASP.NET + Configuring Entity Tags

    - by user336786
    Hello, I have developed an ASP.NET web application that I'm working on putting the finishing touches on. To assist with this, I have been using YSlow. With this tool, I have discovered that I have not properly configured the entity tags of the components on my pages. Unfortunately, I have no idea how to do this. How do I configure entity tags on components within an ASP.NET page? Thank you!

  • NHibernate and Composite Key References

    - by Rich
    I have a weird situation. I have three entities, Company, Employee, Plan and Participation (in retirement plan). Company PK: Company ID Plan PK: Company ID, Plan ID Employee PK: Company ID, SSN, Employee ID Participation PK: Company ID, SSN, Plan ID The problem is in linking the employee to the participation. From a DB perspective, participation should have Employee ID in the PK (it's not even in table). But it doesn't. NHibernate won't let me map the "has many" because the link expects 3 columns (since Employee PK has 3 columns), but I'd only provide 2. Any ideas on how to do this?

  • Allocation of IP Address in Ad hoc systems

    - by Kasturi
    Me and my friends play Age of Empires every weekend and create an Ad-hoc network each time before playing. But each time we all get the SAME IP Address even if a new ad-hoc network is created. Is this something to do with the Game's algorithm or does the laptop remember our previous IP Address. EDIT: What is the algorithm that is used to distribute the IP Addresses? If the algorithm uses random function how come same IP addresses are being allocated.

  • Blackberry Keyboard Lock timeout

    - by Vernon
    I want this blackberry 9700 to "fully lock" as soon as I click the icon for the "Keyboard Lock" application. Currently I have to wait 5 to 7 seconds for the screen to go dark after each time I click the "Keyboard Lock" icon. During that time if something touches the touch pad, then the 5-7 second timer resets and you have to wait another 5 to 7 seconds for the screen to go dark and "fully lock" After it finally goes dark, touching the touch pad does not reset the timer. At that point it is "fully locked" and requires a key to be pressed. How can I get it to "fully lock" as soon as the lock icon is clicked? I want the screen to go dark immediately, and for it to require a key press to request an unlock. I have tried Options - Screen/Keyboard - Backlight Timeout ... etc ... none of that reduces the timeout for the "Keyboard Lock" application. And there does not seem to be an option screen for the "Keyboard Lock" application, that I can find. NOTE: This is occurring with BlackBerry 9700 v5.0.0.330 (Platform 5.1.0.91)

  • Cast Object to JTable?

    - by Chris
    I am trying to implement a ListSelectionListener for some of my JTables. Simply (at the moment) the ListSelectionListener is supposed to simply return the text of the cell that was selected. My program design has several JTables and I would like to have one ListSelectionListener work for them all. In the valueChanged event of the ListSelectionListener I thought it was possible to do something like: private class SelectionHandler implements ListSelectionListener { public void valueChanged(ListSelectionEvent e) { JTable table = (JTable)e.getSource(); String data = (String) table.getValueAt(table.getSelectedRow(), 0); // Print data } } But when I do this I a ClassCastException error. Is there a way to do something like this? One solution I thought of was to compare the source of the event (e.getSource()) to all my JTables to see if they were equivalent (big if block) and then just calling .getValueAt inside that block but that would making the code in the future difficult if tables were to be added or removed.

  • Is SynchronizationContext.Post() threadsafe?

    - by cyclotis04
    This is a pretty basic question, and I imagine that it is, but I can't find any definitive answer. Is SynchronizationContext.Post() threadsafe? I have a member variable which holds the main thread's context, and _context.Post() is being called from multiple threads. I imagine that Post() could be called simultaneously on the object. Should I do something like lock (_contextLock) _context.Post(myDelegate, myEventArgs); or is that unnecessary? Edit: MSDN states that "Any instance members are not guaranteed to be thread safe." Should I keep my lock(), then?

  • How does one go about writing a virtual MIDI interface?

    - by Alex
    I want to do some funky things with controlling MIDI streams, and I'd like to be able to pipe MIDI input into an application like Ableton or Reason. Presumably this involves some sort of driver level work? Ultimately I'd like to write my application in Python, so if there is some Python-based solution, I'd consider it. I'm perfectly fine with using C/C++, though, so that's not a problem.

  • Set environment variable for build in hudson

    - by pbreault
    I am trying to put a maven2 project under continuous integration in hudson. The project uses selenium for some integration testing. Hudson is running on a headless linux. I am using xvfb to start a x server session for selenium. In order to run the tests, I need to export an environment variable named DISPLAY. e.g. export DISPLAY=:99 However, I don't want to set the variable on the box since it would affect all builds. I have tried to do a shell execute using the m2 extra steps plugin but it doesnt work since it is executed in a separate bash file, meaning that environment variables are not persisted. Is there a way to register the environment variable from hudson.

  • Want to bind an input field to a jquery-ui slider handle

    - by BFTrick
    hello, I want to bind an input field to the jquery-ui slider handle. So whenever one value changes I want the other value to also change. Ex: if someone types 1000 into the minimum value input field I want the lower slider handle to move to the 1000 mark. Also if the user drags the lower slider handle to 1000 the input field should reflect that. Making the slider reflect the changes in the input field is easy: $(minYearInput).blur(function () { $("#yearSlider").slider("values", 0, parseInt($(this).val())); }); $(maxYearInput).blur(function () { $("#yearSlider").slider("values", 1, parseInt($(this).val())); }); I just need help making the text fields mimic the slider. $("#yearSlider").slider({ range: true, min: 1994, max: 2011, step: 1, values: [ 1994 , 2011 ], slide: function(event, ui) { //what goes here? } }); Any ideas? A similar question from this site: http://stackoverflow.com/questions/1330008/jquery-ui-slider-input-a-value-and-slider-move-to-location

  • Is there something in MySQL like IN but which uses AND instead of OR?

    - by Skatox
    I need a SQL statement to retrieve records where it key (or any column) is in a associate table, for example: documentId termId 4 1 4 2 3 3 5 1 This: SELECT documentId FROM table WHERE termId IN (1,2,3) ...will retrieve any documentid value where the termid value is 1 or 2 or 3. Is there something like this but return documentid values where the termid values are 1 and 2 and 3? Like an IN but with AND.

  • Common strategies to deal with rounding errors in currency-intensive soft?

    - by Max
    What is your advice on: compensation of accumulated error in bulk math operations on collections of Money objects. How is this implemented in your production code? (things like variable rounding, etc...) theory behind rounding in accountancy. any literature on topic. I currently read Fowler. He mentions Money type, but says nothing on strategies. Older posts on money-rounding (here, and here) do not provide a details and formality I need. Thanks for help.

  • Accessing a Class Member from a First-Class Function

    - by dbyrne
    I have a case class which takes a list of functions: case class A(q:Double, r:Double, s:Double, l:List[(Double)=>Double]) I have over 20 functions defined. Some of these functions have their own parameters, and some of them also use the q, r, and s values from the case class. Two examples are: def f1(w:Double) = (d:Double) => math.sin(d) * w def f2(w:Double, q:Double) = (d:Double) => d * q * w The problem is that I then need to reference q, r, and s twice when instantiating the case class: A(0.5, 1.0, 2.0, List(f1(3.0), f2(4.0, 0.5))) //0.5 is referenced twice I would like to be able to instantiate the class like this: A(0.5, 1.0, 2.0, List(f1(3.0), f2(4.0))) //f2 already knows about q! What is the best technique to accomplish this? Can I define my functions in a trait that the case class extends? EDIT: The real world application has 7 members, not 3. Only a small number of the functions need access to the members. Most of the functions don't care about them.

  • Find MySQL entries with same set of column B values for their common column A value

    - by nnsd44g
    I have: +----+------+------+ | id | A | B | +----+------+------+ | 1 | 1 | 1 | < | 2 | 1 | 2 | < | 3 | 2 | 2 | | 4 | 2 | 3 | | 5 | 3 | 1 | < | 6 | 3 | 2 | < | 7 | 4 | 4 | | 8 | 4 | 5 | +----+------+------+ I need to select the entries that have the same set of B values for their common A value. So, in this case, I need ids 1, 2 and 5, 6 because in those cases the sequence of B values is 1, 2. Is this possible? Thanks!

  • Is there a "pattern" or a group that defines *rc files in *nix environments?

    - by Somebody still uses you MS-DOS
    I'm starting to use command line a little more, and I see there are a lot of ways to configure some config files in my $HOME. This is good, since you can customize it the way you really like. Unfortunately, for begginners, having too many options is a little confusing. For example, I created .bash_alias for some alias I'm using. I didn't even know this option existed, I'm used to simply edit .bashrc. Do exist a pattern, a "good practice", envisioning flexibility and modularity in terms of rc files structure? Do exist a standardization group for this, or every body just creates it's own configuration setup?

  • Can you run a specific tomcat Web Application under another user?

    - by Boaz
    Hi, We're developing a web-app running under tomcat which relies on Java User preferences to store all kind of settings. That works great, but we've run into problem where we needed to set up another staging web-app which allows you to test settings before settings them live. The core of the problem lies in the fact that Java User preferences are the same for all web-app due to the fact that all of them run under the tomcat user (configurable). For legacy reasons I can not at the moment change my preferences structure, so I'm hoping for a solution on the the tomcat configuration side. Is it possible to designate a different user credentials for a specific web-app in tomcat? Thanks, Boaz

  • Are there freezing issues with the Seagate Barracuda ST31500341AS anymore?

    - by Neil
    I found this hard drive on NewEgg: Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive (bare drive) - OEM http://www.newegg.com/Product/Product.aspx?Item=N82E16822148337 And there are quite a few substantial bad reviews about the drive freezing periodically. If you search for a bit, you can find several forums with people having problems, but of course forums don't get updated when resolutions to those problems are found. I'm just wondering, does anyone know what the final verdict regarding the freezing issue with these hard drives is?

  • Hibernate ResultTransformer with JPA API

    - by Timo Westkämper
    Has anyone figured out a smart way to do query result transformation through a similar mechanism like specifying a ResultTransformer in Hibernate? All I can think of is transforming each result row after it has been returned by the Query. Is there any other way? For constructor projections (e.g. new DTO(arg1, arg2)) it can be defined in the JPQL query, at least for Hibernate, but how about other cases?

  • What does it mean when you try to print an array or hash using Perl and you get, Array(0xd3888)?
