  • jQuery: add border on hovered element but NOT parents

    - by John Isaacks
    I have this code: var originalBorder = container.css("border"); container.hover(function(event) { event.stopPropagation(); $(this).css("border", "1px solid "+options.color); },function(){ $(this).css("border", originalBorder); }); Which I am using to add a border to the currently hovered element. However for example if a span is inside a div they are both getting borders. I only want to target the span. I thought that adding event.stopPropagation() would do the trick (this is what I would do in Flex, which is what I am more used to) but I guess this is a live event which I dont even understand what that means. So basically how can target the youngest element without triggering the parents? Thanks!!

  • JMS message. Model to include data or pointers to data?

    - by John
    I am trying to resolve a design difference of opinion where neither of us has experience with JMS. We want to use JMS to communicate between a j2ee application and the stand-alone application when a new event occurs. We would be using a single point-to-point queue. Both sides are Java-based. The question is whether to send the event data itself in the JMS message body or to send a pointer to the data so that the stand-alone program can retrieve it. Details below. I have a j2ee application that supports data entry of new and updated persons and related events. The person records and associated events are written to an Oracle database. There are also stand-alone, separate programs that contribute new person and event records to the database. When a new event occurs through any of 5-10 different application functions, I need to notify remote systems through an outbound interface using an industry-specific standard messaging protocol. The outbound interface has been designed as a stand-alone application to support scalability through asynchronous operation and by moving it to a separate server. The j2ee application currently has most of the data in memory at the time the event is entered. The data would consist of approximately 6 different objects; a person object and some with multiple instances for an average size in the range of 3000 to 20,000 bytes. Some special cases could be many times this amount. From a performance and reliability perspective, should I model the JMS message to pass all the data needed to create the interface message, or model the JMS message to contain record keys for the data and have the stand-alone Java application retrieve the data to create the interface message?

  • take performance as the only criterion for a smal site, which framework should I choose on a shared

    - by john
    Dear friends, I'm trying to set up a small full functional website for a small community on a shared hosting. Scientific computing is quite heavy. Scalability is not important. The only criterion is performance. Which framework would you suggest among the following:(or more) from your list) 1)Ruby on Rails 2) Grails 3) asp.net 4) zend I'm really new to this area, only starting reading some books and googling different blogs...so your expertise is really appreciated! thanks!

  • Where do I control the behavior of the "X" close button in the upper right of a winform?

    - by John at CashCommons
    I'm venturing into making my VB.NET application a little better to use by making some of the forms modeless. I think I've figured out how to use dlg.Show() and dlg.Hide() instead of calling dlg.ShowDialog(). I have an instance of my modeless dialog in my main application form: Public theModelessDialog As New dlgModeless To fire up the modeless dialog I call theModelessDialog.Show() and within the OK and Cancel button handlers in dlgModeless I have Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.OK Me.Hide() End Sub Private Sub Cancel_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Hide() End Sub and that seems to work fine. The "X" button in the upper right is getting me, though. When I close the form with that button, then try to reopen the form, I get ObjectDisposedException was unhandled. Cannot access a disposed object. I feel like I'm most of the way there but I can't figure out how to do either of the following: Hide that "X" button Catch the event so I don't dispose of the object (just treat it like I hit Cancel) Any ideas? The class of this dialog is System.Windows.Forms.Form. Thanks as always!

  • Sequential searching with sorted linked lists

    - by John Graveston
    struct Record_node* Sequential_search(struct Record_node *List, int target) { struct Record_node *cur; cur = List->head ; if(cur == NULL || cur->key >= target) { return NULL; } while(cur->next != NULL) { if(cur->next->key >= target) { return cur; } cur = cur->next; } return cur; } I cannot interpret this pseudocode. Can anybody explain to me how this program works and flows? Given this pseudocode that searches for a value in a linked list and a list that is in an ascending order, what would this program return? a. The largest value in the list that is smaller than target b. The largest value in the list that is smaller than or same as target c. The smallest value in the list that is larger than or same as target d. Target e. The smallest value in the list that is larger than target And say that List is [1, 2, 4, 5, 9, 20, 20, 24, 44, 69, 70, 71, 74, 77, 92] and target 15, how many comparisons are occurred? (here, comparison means comparing the value of target)

  • PHP - How to determine if request is coming from a specific file.

    - by John
    I have fileA.php on SERVER_A and fileB.php on SERVER_B fileB.php makes a curl request to fileA.php for it's contents How can fileA.php determine that the request is coming specifically from fileB.php? -- I was thinking about sending the $_SERVER['SCRIPT_NAME'] in fileB.php to fileA.php but since someone can go into fileB.php or any file in general and just do $_SERVER['SCRIPT_NAME'] = 'fileB.php'; it's not really that secure. So how can I determine, for security reasons, that the request is coming from a specific file on a different server?

  • What's the Flash equivalent of FlexEvent.CREATION_COMPLETE

    - by John
    I'm moving some Flex classes to pure Flash/AS3 to be part of a shared library. I have an event listener on FlexEvent.CREATION_COMPLETE to create and add display-objects once things are running, but I don't know the right way to do this in Flash? edit: Maybe if my class subclasses Sprite rather than a Flex class, I can add children in the constructor, I don't need to wait for a "construction complete" event?

  • Converting c++ string to int

    - by skazhy
    Hi! I have the following data in a c++ string John Doe 01.01.1970 I need to extract the date and time from it into int variables. I tried it like this: int last_space = text_string.find_last_of(' '); int day = int(text_string.substr(last_space + 1, 2)); But I got invalid cast from type ‘std::basic_string’ to type ‘int’. When I extract the "John Doe" part in another string variable, all works fine. What's wrong? I am trying to compile it with g++ -Wall -Werror.

  • Method-Object pairs in Java

    - by John Manak
    I'd like to create a list of method-object pairs. Each method is a function returning a boolean. Then: foreach(pair) { if method evaluates to true { do something with the object } } One way of modelling this that I can think of is to have a class Constraint with a method isValid() and for each constraint produce an anonymous class (overriding the isValid() method). I feel like there could be a nicer way. Can you think of any?

  • HTML / Conditional Comments - Do conditional comments behave as expected across browsers?

  • Which PHP calendar will suit my needs? Or build my own?

    - by John
    There are so many web based calendars out there that I'm not sure which will best suit my purposes. I want to create an events calendar, which I suppose looks and functions in much the same way as google calendar. But users shouldn't need to sign up for a gmail account or a google account. Users of my social network website should be able to create events in the calendar and share it with other friends in their "friend network". In month, year or day views, you can mouse hover events to see a bubble dialog that lists events in detail. People need to pay a monthly fee to use my website (not sure if this prevents me from using google apps). So is something like Google Calendar the way to go? Or are there other php/javascript calendars out there that already meet my needs? Or will it just save me more time to build my own?

  • How to test if an array contains a pair of numbers whose product is odd?

    - by John
    How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."

  • Have an external java application by notified of changes to Entity EJBs in JBoss AS

    - by John
    I'm trying to connect an external application to a JBoss AS container. The external application is a Java application that is currently being notified of changes to database entities through a JMS topic. I've added an EntityLifecycleListener class to all my entities that publishes a serialized (and unwrapped) copy of the entity to the JMS topic. The problem is that this implementation ignores the transaction boundaries of the JBoss container. For example, the @PostUpdate event can be fire, generating the JMS message for that entity, but the transaction could be rolled back causing the external application to be notified of an invalid change and become unsync'd. I need my external application to only be notified of successful commits to the database, but I need to be able to publish the entire java POJO to the external application. Is there an official way of doing this?

  • Javascript split with RegEx

    - by Rohan
    Hey again, I just asked a question about Regex, and received a great answer: http://stackoverflow.com/questions/3047201/javascript-split-without-losing-character Now, I have another question. My current Regex looks like this: var split = text.split(/(?=\w*\d*\d:\d\d)/); Basically, I'm trying to split using the timestamps (eg - 9:30 or 10:30, the difference between them is the extra digit in the latter). How do I go about this? Currently, if I have these two: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. The splits are : 9:30 pm The user did action A. ---- 1 ---- 0:30 pm Welcome, user John Doe. How do I add an optional check for the first character in the timestamp? Thanks!

  • XHTML 1.0 DocType ignored in all browsers?

    - by John
    I was testing this, since I understood using XHTML let me use any valid XML for empty <div> elements: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <title>Test</title> </head> <body> <div style="border:solid 10px black; width:100px; height:100px"></div> <div style="border:solid 10px red; width:100px; height:100px"></div> <div style="border:solid 10px blue; width:100px; height:100px"></div> <div style="border:solid 10px black; width:100px; height:100px" /> <div style="border:solid 10px red; width:100px; height:100px" /> <div style="border:solid 10px blue; width:100px; height:100px" /> </body> </html> It doesn't work in any browser I try... this is how FireBug tells me it understands the document: <html> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/> <title>Test</title> </head> <body> <div style="border: 10px solid black; width: 100px; height: 100px;"/> <div style="border: 10px solid red; width: 100px; height: 100px;"/> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> <div style="border: 10px solid black; width: 100px; height: 100px;"> <div style="border: 10px solid red; width: 100px; height: 100px;"> <div style="border: 10px solid blue; width: 100px; height: 100px;"/> </div> </div> </body> </html> I'm a bit confused what the point is of using XHTML if I have to do this, I might as well just use HTML? Note, that setting the content type to content="application/xhtml+xml" makes no difference in FF3 at least.

  • Templating Word Documents in C#

    - by NullGeo
    I was wondering if there is a library out there such that it could give me the ability to fill in word templates with custom values. For example: Following could be the content of the Word Document {Address} {PhoneNumber} Hello {Name}, How are you doing? In C# I would like to do something like this to replace all the placeholders in the Word document: using(WordDocument doc = WordDocument.Load("Mail.docx")){ var person = new {Name = "John Smith", Address="42 Wallaby Way, Sydney", PhoneNumber="555-555-5555"}; doc.Template(person); doc.Print(); } The resulting document would look like this: 42 Wallaby Way, Sydney 555-555-5555 Hello John Smith, How are you doing? Any libraries out there (preferably free) that let's me do this? Edit: I am not asking you to find anything that let's me do this. If that was the case, I would do a Google search by myself. Honestly, all I am asking is "has anybody used a library in the past to do this exact thing."

  • XPath Query - Select relative top level nodes

    - by John
    I'm trying to iterate over some elements in an XML document that may be nested, but as I iterate over them I may be removing some from the tree. I'm thinking the best way is to do this recursively, so I'm trying to come up with an XPath Query that will select all the top-level nodes relative to the current node. //foo[not(ancestor::foo)] works great at the document level, but I'm trying to figure out how to do this from a relative query. <foo id="1"> <foo id="2" /> <foo id="3"> <foo id="4"> <bar> <foo id="5"> <foo id="6" /> </foo> <foo id="7" /> </bar> </foo> </foo> </foo> If the current node is foo#3, I only want to select foo#4. When the current node is foo#4, I only want to select foo#5 and foo#7. I think I'm trying to select any descendant foo nodes of the current node, but without any ancestor foo nodes between the current node and the node I'm selecting. My conundrum is if we're already inside a foo node, not(ancestor::foo) doesn't help.
