  • jquery reset conditional filter

    - by VictorS
    I have 2 dropdown lists on my webform and using jquery trying to filter/reset filter 2nd dropdown elements based on 1st dropdown selection. $(document).ready(function() { $('#dropdown1').change(function(e) { switch ($(this).val()) { case "4": //this removal works $('#dropdown2').filter(function() { return ($(this).val() == 16); }).remove(); break; ................. default: //how would I restore filter here? } } }); Removing part works, so it filters item with no problem, but I have difficulty restoring the filter on dropdown 2 if something else is chosen in dropdown 1. I was trying to use .hide() and .show() instead of .remove() but it doesn't seem to work on IE6 at least.

  • Extracting text from PDF with Poppler (C++)

    - by nico
    I'm trying to get my way through Poppler and its (lack of) documentation. What I want to do is a very simple thing: open a PDF file and read the text in it. I'm then going to process the text, but that doesn't really matter here. So... I saw the poppler_page_get_text function, and it kind of works, but I have to specify a selection rectangle, which is not very handy. Isn't there just a very simple function that would output the PDF text in order (maybe line by line?). Thank you Nicola

  • lock-free memory reclamation with 64bit pointers

    - by JDonner
    Herlihy and Shavit's book (The Art of Multiprocessor Programming) solution to memory reclamation uses Java's AtomicStampedReference<T>;. To write one in C++ for the x86_64 I imagine requires at least a 12 byte swap operation - 8 for a 64bit pointer and 4 for the int. Is there x86 hardware support for this and if not, any pointers on how to do wait-free memory reclamation without it?

  • How to handle Foreign key for optional field in .NET

    - by brz dot net
    What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

  • Jquery: How can I Get/Set html of a String Variable by using Jquery Selectors ?

    - by ryan.dingy
    Hi all. Firstly, sorry for my English (I'm from China). By reading this article(http://stackoverflow.com/questions/2421719/how-to-apply-jquery-element-selection-to-a-string-variable), I can successfully get Elements from a String which stores HTML text. For example: var htmlstr = "<div><ul><li>some text 1</li></ul></div><div><ul id=list><li>some text 2</li></ul></div>"; var s = $('ul#list', $(htmlstr)).html(); s will be <li>some text 2</li>. It's what I want. But the question is, if I want to add another LI element to this string (htmlstr) how can I do? I set s = new html string but htmlstr doesn't change. Thanks

  • What is the best way to embed controls in a list/grid

    - by Brad
    I have a table of about 450 rows that I would like to display in a graphical list for users to view or modify the line items. The users would be selection options from comboboxes and selecting check boxes etc. I have found a listview class that extends the basic listview to allow for embeding objects but it seems kind of slugish when I load all the rows into it. I have used a datagridview in the past for comboboxes and checkboxes, but there was a lot of time invested in getting that up and running...not a big fav of mine. I am looking for sugestions how I can do this with minimal overhead. thanks c#, vs2008, .net 2.0, system.windows.forms

  • CoreData and many NSArrayController

    - by unixo
    In my CoreData Application, I've an outline view on left of main window, acting as source list (like iTunes); on the right I display a proper view, based on outline selection. Each view has its components, such as table view, connected to array controller, owned by the specific view. Very often different views display same data, for example, a table view of the same entity. From a performance point of view, is better to have a single array controller per entity and share it between all views or does CoreData cache avoid memory waste?

  • Refactoring Singleton Overuse

    - by drharris
    Today I had an epiphany, and it was that I was doing everything wrong. Some history: I inherited a C# application, which was really just a collection of static methods, a completely procedural mess of C# code. I refactored this the best I knew at the time, bringing in lots of post-college OOP knowledge. To make a long story short, many of the entities in code have turned out to be Singletons. Today I realized I needed 3 new classes, which would each follow the same Singleton pattern to match the rest of the software. If I keep tumbling down this slippery slope, eventually every class in my application will be Singleton, which will really be no logically different from the original group of static methods. I need help on rethinking this. I know about Dependency Injection, and that would generally be the strategy to use in breaking the Singleton curse. However, I have a few specific questions related to this refactoring, and all about best practices for doing so. How acceptable is the use of static variables to encapsulate configuration information? I have a brain block on using static, and I think it is due to an early OO class in college where the professor said static was bad. But, should I have to reconfigure the class every time I access it? When accessing hardware, is it ok to leave a static pointer to the addresses and variables needed, or should I continually perform Open() and Close() operations? Right now I have a single method acting as the controller. Specifically, I continually poll several external instruments (via hardware drivers) for data. Should this type of controller be the way to go, or should I spawn separate threads for each instrument at the program's startup? If the latter, how do I make this object oriented? Should I create classes called InstrumentAListener and InstrumentBListener? Or is there some standard way to approach this? Is there a better way to do global configuration? Right now I simply have Configuration.Instance.Foo sprinkled liberally throughout the code. Almost every class uses it, so perhaps keeping it as a Singleton makes sense. Any thoughts? A lot of my classes are things like SerialPortWriter or DataFileWriter, which must sit around waiting for this data to stream in. Since they are active the entire time, how should I arrange these in order to listen for the events generated when data comes in? Any other resources, books, or comments about how to get away from Singletons and other pattern overuse would be helpful.

  • Making GridView Respond to 2 Drop Down Lists

    - by raziiq
    Hi there. I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists. For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List. BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database. Any Suggestions??

  • Selecting item from set given distribution

    - by JH
    I have a set of X items such as {blower, mower, stove} and each item has a certain percentage of times it should be selected from the overall set {blower=25%,mower=25%,stove=75%} along with a certain distribution that these items should follow (blower should be selected more at the beginning of selection and stove more at the end). We are given a number of objects to be overall selected (ie 100) and a overall time to do this in (say 100 seconds). I was thinking of using a roulette wheel algorithm where the weights on the wheel are affected by the current distribution as a function of the elapsed time (and the allowed duration) so that simple functions could be used to determine the weight. Are there any common approaches to problems like this that anyone is aware of? Currently i have programmed something similar to this in java using functions such as x^2 (with correct normalization for the weights) to ensure that a good distribution occurs. Other suggestions or common practices would be welcome :-)

  • db2 jdbc driver does not release table locks

    - by as
    situation: We have a web service running on tomcat accessing DB2 database on AS400, we are using JTOPEN drivers for JNDI connections handled by tomcat. For handling transactions and access to database we are using Spring. For each select system takes JDBC connection from JNDI (i.e. from connection pool), does selection, and in the end it closes ResultSet, Statement and releases Connection in that order. That passes fine, shared lock on table dissappears. When we want to do update the same way as we did with select (exception on ResultSet object, we don't have one in such situation), after releasing Connection to JNDI lock on table stays. If we put maxIdle=0 for number of connections in JNDI configuration, this problem disappears, but this degrades performances, we have cca 100 users online on that service, we need few connections to be alive in pool. What do you suggest?

  • Custom ListView Row, can no longer select rows...

    - by LDK
    Here's my ScrollView: middle: SC.ScrollView.design({ layout: { top: 36, bottom: 32, left: 0, right: 0 }, backgroundColor: '#ccc', contentView: SC.ListView.design({ contentBinding: 'Spanish.wordsController.arrangedObjects', selectionBinding: 'Spanish.wordsController.selection', contentValueKey: "word", contentDisplayProperties: 'word english'.w(), selectOnMouseDown: YES, exampleView: Spanish.CustomListItemView }) }) and here is my custom listView row: Spanish.CustomListItemView = SC.View.extend({ render: function(context, firstTime){ var content = this.get('content'); var word = content.get('word'); var english = content.get('english'); context = context.begin().push('&nbsp;%@ (%@)'.fmt(word,english)).end(); return sc_super(); } }); The above works as expected, except that I can no longer select views. When I comment out "exampleView: Spanish.CustomListItemView" I can select rows, but they are no longer formatted properly. Why can I no longer select rows when I use exampleView?
