  • IE 7 can't bind event (using .live()) to dynamically created element using .load()

    - by petron
    Hi All - I'm having trouble getting IE7 to keep a click event bound to an element that is added to the DOM using .load(). Here's some code: $('.mybtn').live('click', function(e){ e.preventDefault(); $('#mypage').load('load-this-page.htm'); }); And here's the html <div id="mypage"> <a href="#" class="mybtn">clickme</a> // stuff goes here </div> On page load the click works but once the div is loaded via the clickme link the click stops working in IE7. The clickme link is within the div on load and also within the load() loaded html file that's why I'm using live(). This code works in FF 3.6, fyi. Anyone have any idea what's up (besides the fact the IE sucks balls)? Thanks!

  • Accessing "current class" from WPF custom MarkupExtension

    - by chaiguy
    I'm attempting to write a custom MarkupExtension to make my life easier by giving me a better way to specify bindings in XAML. However I would like to know if there is any way I can access the object that represents the file the MarkupExtension is used in. In other words, suppose I have a UserControl that defines a particular rendition of a data model of my program. This control has lots of visual stuff like grids, borders and general layout. If I use my MarkupExtension on a particular property of some element in this UserControl, I want to access the instance of the UserControl, without knowing what type it is (I plan on using reflection). Is this at all possible?

  • Creating Pages or Windows in WPF

    - by cmptrer
    Hey all, I'm new to using WPF. I have the following program I want to create: -Application opens up with one button -User clicks button and it takes them to a new page with various input. I'm confused about how I need to do this. I tried opening a new window, but I don't want a window to open up, I want it to be all one Window. I tried creating a new page and navigating to it using NavigationService but couldn't get it to work. Basically I want to create a workflow where the user enters some stuff, clicks the next button and is taken to a new page to enter some more information. Can anyone point me in the right direction?

  • $HOME git repo (selectively) to github?

    - by user428502
    I keep many files in my home directory under git. Important dotfiles, my thesis, etc. I want to push certain files to github, e.g., my emacs configuration, to share. Obviously, I don't want to push the entire repo. Are submodules the way to go? My first thought is to make a directory ~/github/emacs, and rsync selective files here, then add a submodule under that directory, pointing to github, to push. Is this a good idea, or is there a better way? (I don't want my local git repo storing all files to get muddled up with this stuff, though.)

  • sqrt(int_value + 0.0) ? The point?

    - by Earlz
    Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler?

  • What books help one to learn to read code?

    - by Daniel
    Lion's Commentary on Unix Sixth Edition with Source Code is a wonderful book to learn how to read code. Reading code is important -- how does one learn how to write excellent code without having read excellent code? But, sadly, while great writers, of fiction and non-fiction, all spend a great deal of time reading stuff, we, programmers, seem to avoid it like the plague. Worse still, programming books usually go the same way. They might show a pattern or a style, but they often avoid showing good, complex code, and helping one go through it. There are exceptions, of course. I hope. So, with that in mind, what books are to be found which help one learn how to read code?

  • Parsing a string representing a float *with an exponent* in Python

    - by Lucas
    Hi, I have a large file with numbers in the form of 6,52353753563E-7. So there's an exponent in that string. float() dies on this. While I could write custom code to pre-process the string into something float() can eat, I'm looking for the pythonic way of converting these into a float (something like a format string passed somewhere). I must say I'm surprised float() can't handle strings with such an exponent, this is pretty common stuff. I'm using python 2.6, but 3.1 is an option if need be.

  • Will html5 and Javascript replace native applications?

    - by nimo
    I recently attended a conference on future of the web and web development and it was a lot of focus on HTML5 and how it will impact the way we look at the web and how we will use it. The majority of the speakers meant that it will replace native application on your desktop as well as in your mobile phone. I agree that you will be able to make a lot of great stuff with the new technology take bespin for example and the <video> and <canvas> tag will be amazing, but will it completely remove the need for native applications? Is there something you cannot do with Javascript and HTML5?

  • rails: has_many :through + polymorphism validation?

    - by ramonrails
    I am trying to achieve this. Any hints? A project has many users through join model A user has many projects through join model Admin class inherits User class. It also has some Admin specific stuff. Admin like inheritance for Supervisor and Operator Project has one Admin, One supervisor and many operators. Now I want to 1. submit data for project, admin, supervisor and operator in a single project form 2. validate all and show errors on the project form. Project has_many :users, :through = :projects_users User has_many :projects, :through = :projects_users ProjectsUser = :id integer, :user_id :integer, :project_id :integer, :user_type :string ProjectUser belongs_to :project, belongs_to :user, :polymorphic = true Admin < User Supervisor < User Operator < User Is the approach correct? Any and all suggestions are welcome.

  • drupal hook just before inserting/updating user info

    - by Senthil
    Hi, I want to hook into drupal's user registration and be able to stop it or allow it to proceed just before database insert. All validations and 3rd party stuff must be done and just before inserting I need to hook in. What is the hook and the operation to do this? I tried 'validate' operation in the hook_user. But, after I check against my logic and let the registration proceed, it should not fail due to some other validation. If I let it proceed, no application logic after that should stop the registration (unless the DB engine fails or something of course). If I stop it, I will set a form error so that nothing happens. How can this be accomplished? P.S. I am using Drupal 6.16

  • Microsoft SQL Server 2005/2008 SSIS are oversized

    - by Ice
    In this case i'm old style and loved 'my fathers DTS' from SQL 2000. Most of the cases i have to import a flatfile into a table. In a second step i use some procedures (with the new MERGE-Statement) to process the imported content. For Export, i define a export-table and populate it with a store proc (containing a MERGE-Statement) and in a second step the content will be exported to a flat file. In some cases there is no flat file because there is annother sql-server or in rare cases an ODBC-Connection to a sybase or similar. What do you think? When it comes to complex ETL-Stuff the SSIS may be the right tool...but i haven't seen such a case yet.

  • MySQL Query WHERE Including CASE or IF?

    - by handfix
    Strange problem. My Query looks like SELECT DISTINCT ID, `etcetc`, `if/elses over muliple joined tables` FROM table1 AS `t1` # some joins, eventually unrelated in that context WHERE # some standard where statements, they work/ CASE WHEN `t1`.`field` = "foo" THEN (`t1`.`anOtherField` != 123 AND `t1`.`anOtherField` != 456 AND `t1`.`anOtherOtherField` != "some String") WHEN `t1`.`field` = "bar" THEN `t1`.`aSecondOtherField` != 12345 END #ORDER BY CASE etc. Standard Stuff Apperantly MySQL returns a wrong rowcount and I think my problem is in the logic of the WHERE ... CASE statement. Maybe with the brackets? Maybe I should go for operator OR and not AND? Should my the second WHEN include brackets also, even when I only compare one field? Should I use IF and not CASE? Basically I want to exclude some rows with specific values IF theres a specific value in field foo or bar I would try that all out, but it takes a huge amount of time to complete that query... :(

  • How to add .Net3.5 dll into .Net2.0 project?

    - by macias
    I have a dll which is based on .net 3.5 -- it uses internally for example Linq, but the exposed API is straightforward, no fancy stuff. Since C# generics are resolved at compile time I assume that for calling party all it counts is API (all public parts). However when I try to use this dll from net2.0 project I get info, that the dll cannot be referenced because the dll or one of its dependencies requires a later version of .net framework. I can install any .net version I want on target computer (when entire app is installed), but I cannot change .net version for the project itself. So: how to solve this? When adding a C dll to this project I had no such problems, so are C# dlls self-contained or not?

  • Custom Output => List of Errors interpretation in VS2008 IDE.

    - by Hamish Grubijan
    Hello, I have a "database solution" project in VS2008 - it generates SQL for more than one DB vendor from some sort of templates. In order to save time, I also have a tool in VS2008 configured (a Python script), which can compile an individual stored procedure. Now, with the Python script I have the freedom of processing the output and have it take on whatever form I want. I am toying with an idea of having these errors and warnings somehow recognized and populating the click-able Error / Warning list. This is what a typical Oracle error looks like: LINE/COL ERROR -------- ----------------------------------------------------------------- 324/5 PL/SQL: Statement ignored 324/82 PLS-00363: expression 'VSOURCE_SYSTEM_ID' cannot be used as an assignment target Warning: Procedure created with compilation errors. PROCEDURE: ADD_PROPOSED error on creation Errors for PROCEDURE ADD_PROPOSED: LINE/COL ERROR This might be a long shot, but it is worthwhile for me. I do this stuff a lot. Thank you!

  • Grails Services / Transactions / RuntimeException / Testing

    - by Rob
    I'm testing come code in a service with transactional set to true , which talks to a customer supplied web service the main part of which looks like class BarcodeService { .. /// some stuff ... try{ cancelBarCodeResponse = cancelBarCode(cancelBarcodeRequest) } catch(myCommsException e) { throw new RuntimeException(e) } ... where myCommsException extends Exception .. I have a test which looks like // As no connection from my machine, it should fail .. shouldFailWithCause(RuntimeException){ barcodeServices.cancelBarcodeDetails() } The test fails cause it's catching a myCommsException rather than the RuntimeException i thought i'd converted it to .. Anyone care to point out what i'm doing wrong ? Also will the fact that it's not a RuntimeException mean any transaction related info done before my try/catch actually be written out rather than thrown away ?? Thanks

  • Remove anchor from URL in C#

    - by kcoppock
    I'm trying to pull in an src value from an XML document, and in one that I'm testing it with, the src is: <content src="content/Orwell - 1984 - 0451524934_split_2.html#calibre_chapter_2"/> That creates a problem when trying to open the file. I'm not sure what that #(stuff) suffix is called, so I had no luck searching for an answer. I'd just like a simple way to remove it if possible. I suppose I could write a function to search for a # and remove anything after, but that would break if the filename contained a # symbol (or can a file even have that symbol?) Thanks!

  • How to run a .class file in Windows 7 OS?

    - by jNoob
    Hi, This is probably a stupid question, but how do I run a class file on windows 7? I usually create my own .java files and then use a basic IDE (with JDK6) to compile it to a class and run it automatically. My professor gave a .class file that we are supposed to play with extensively but I have no idea how to to run it here. Note that I cannot run it by typing: java classname.class because it contains gui stuff especially buttons and such. If I do the above I get the following error: java.lang.NoClassDefFoundError: Test1/2/class Caused by: java.lang.ClassNotFoundException: Test1.2.class at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Could not find the main class: Test1.2.class. Program will exit. Exception in thread "main" Any help would be highly appreciated. Thanks.

  • input URL, output contents of "view page source", i.e. after javascript / etc, library or command-li

    - by Ryan Berckmans
    I need a scalable, automated, method of dumping the contents of "view page source" (DOM) to a file. Programs such as wget or curl will non-interactively retrieve a set of URLs, but do not execute javascript or any of that 'fancy stuff'. My ideal solution looks like any of the following (fantasy solutions): cat urls.txt | google-chrome --quiet --no-gui \ --output-sources-directory=~/urls-source (fantasy command line, no idea if flags like these exist) or cat urls.txt | python -c "import some-library; \ ... use some-library to process urls.txt ; output sources to ~/urls-source" As a secondary concern, I also need: dump all included javascript source to file (a la firebug) dump pdf/image of page to file (print to file)

  • Fast way to pass a simple java object from one thread to another

    - by Adal
    I have a callback which receives an object. I make a copy of this object, and I must pass it on to another thread for further processing. It's very important for the callback to return as fast as possible. Ideally, the callback will write the copy to some sort of lock-free container. I only have the callback called from a single thread and one processing thread. I only need to pass a bunch of doubles to the other thread, and I know the maximum number of doubles (around 40). Any ideas? I'm not very familiar with Java, so I don't know the usual ways to pass stuff between threads.

  • Tracing all events in VB.NET

    - by MatsT
    I keep running into situations where I don't know what event I have to listen to in order to execute my code at the correct time. Is there any way to get a log of all events that is raised? Any way to filter that log based on what object raised the event? EDIT: Final solution: Private Sub WireAllEvents(ByVal obj As Object) Dim parameterTypes() As Type = {GetType(System.Object), GetType(System.EventArgs)} Dim Events = obj.GetType().GetEvents() For Each ev In Events Dim handler As New DynamicMethod("", Nothing, parameterTypes, GetType(main)) Dim ilgen As ILGenerator = handler.GetILGenerator() ilgen.EmitWriteLine("Event Name: " + ev.Name) ilgen.Emit(OpCodes.Ret) ev.AddEventHandler(obj, handler.CreateDelegate(ev.EventHandlerType)) Next End Sub And yes, I know this is not a good solution when you actually want to do real stuff that triggers off the events. There are good reasons for the 1 method - 1 event approach, but this is still useful when trying to figure out which of the methods you want to add your handlers to.

  • Best practice: How to persist simple data without a database in django?

    - by Infinity
    I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

  • iOS sample projects to learn from

    - by DerMike
    I am just starting iOS development. I read some tutorials, watched stuff on iTunes U and wrote some sample code myself. Now I want to take the next step. I want to learn about best practices for iOS development in XCode. Are there any well written and well organized iOS projects that one could take a look at? (As I see it, iOS is not exactly the place for open source enthusiasts, however.) Thanks Mike.

  • jQuery Dialog theme not being applied

    - by Tim
    I'm using jquery-1.4.2.min.js and jquery-ui-1.8.1.custom.min.js. According to Firebug, both minimized scripts have been loaded. They both appear in the dropdown list on Firebug's Scripts tab. The dialog is launching, but there's no background and so the text below it shows through, and there's no "window" stuff at all, no titlebar, no X button. Just the floating/draggable text with a -close- link at the top left corner. I was under the impression from reading these pages http://jqueryui.com/demos/dialog/ http://jqueryui.com/themeroller/ that the UI theme-driven appearance would be automatically applied to the dialog when it was invoked using this barebones call: $('#dialog').dialog() I would be grateful for suggestions on how to troubleshoot this. Thanks

  • [C#] How to share a variable between two classes?

    - by Altefquatre
    Hello, How would you share the same object between two other objects? For instance, I'd like something in that flavor: class A { private string foo_; // It could be any other class/struct too (Vector3, Matrix...) public A (string shared) { this.foo_ = shared; } public void Bar() { this.foo_ = "changed"; } } ... // inside main string str = "test"; A a = new A(str); Console.WriteLine(str); // "test" a.Bar(); Console.WriteLine(str); // I get "test" instead of "changed"... :( I read there is some ref/out stuff, but I couldn't get what I'm asking here. I could only apply some changes in the methods scope where I was using ref/out arguments... I also read we could use pointers, but is there no other way to do it? Thanks Altefquatre
