  • jQuery: Any way to "refresh" event handlers?

    - by Legend
    I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?

  • Function to get a string and return same after processing in C

    - by C0de_Hard
    I am working on a code which requires a function. This function gets a string as input and returns a string. What I have planned so far is to get a str[], remove all $'s and spaces, and store this in another string which is returned later: char *getstring(char str[]) { int i=0; char rtn[255]; while (i<strlen(str)) { if (str[i] != " " || str[i] != "$" ) rtn[i] = str[i]; else rtn[i] = ''; } return str; } I dont feel like this will work. Any ideas?? :-S

  • PDO:sqlite doesnt INSERT data, yet no error

    - by Phonethics
    try { $res = $db-exec($sql); if ($res === FALSE) { print_r($db-errorInfo()); die(); } } catch(PDOException $e) { die($e-getCode().':'.$e-getMessage()); } catch(Exception $e) { die($e-getCode().':'.$e-getMessage()); } No error info, and neither does it get caught as an exception. Yet $res is FALSE and no data gets inserted. Array ( [0] => ) But when I echo $sql and enter that query in SQLiteManager, it works inserting the data.

  • Hibernate entities: columns without entity properties

    - by lewap
    Is there a way to "magically" persist a column which is not represented as a property in an entity? Concretely I want to add audit info to an entity without having the audit info on the entity. The audit values are not stored in the entity, but are retrieved from the environment at the time of persisting the entity. This happens in a AuditInfoUserType. The nullSafeSet gets the info from the SecurityContext, instead of reading from the entity. In the hibernate mapping, however, the audit info properties have to be defined. Is there a way in hibernate to define columns without properties?

  • How do you make long SQL invoked from other code readable?

    - by Artem
    This is a very open question, but I think it can be very beneficial for SQL readability. So you have a Java program, and you are trying to call a monster SQL statement from it, with many subqueries and joins. The starting point for my question is a string constant like this: static string MONSTER_STATEMENT = "SELECT " + " fields" + "WHERE "+ " fieldA = (SELECT a FROM TableC) " + "AND fieldB IN (%s)" + "AND fieldC = %d " + "FROM " " tableA INNER JOIN tableB ON ..."; It later gets filled using String.format and executed. What are you tricks for making this kind of stuff readable? Do you separate your inner joins. Do you indent the SQL itself inside the string? Where do you put the comments? Please share all of the tricks in your arsenal.

  • problem using keil uvision 3

    - by Blossom
    I am trying to compile a C code using Keil uvision 3. The entire code gets compiled only if I use large memory model by choosing option xdata for target. To use this model I have to use external data RAM which is not possible for me due to some reasons. So I decided to go with pdata option. Can anybody please help me with the exact steps to be carried out for using pdata? I am using 89V51RD2. I am much confused with the options like BL51 MISC, BL51 Locate etc.

    I'm looking at building an exhaustive function that returns a friendly name for the Users Operating System.

  • How to start SQL Server in a remote machine using code from Delphi?

    - by MLB
    Hi there: I am developing an application (Delphi 7, windows XP) that uses a connection to a remote SQL Server. Sometimes, that server is down, and I want to do something to start it. I was trying to start SQL Server in a local context, and it was fine, it worked... But the point is that I have to start it up from a remote machine. I can see SQL Server status from a remote server, but I can't start it up... Maybe it gets problems because of user and password, but where to specify the login to the remote machine? Do you have any idea to do this??? I am sorry about my English. Thanks.

  • Any good idioms for error handling in straight C programs?

    - by Will Hartung
    Getting back in to some C work. Many of my functions look like this: int err = do_something(arg1, arg2, arg3, &result); With the intent the result gets populated by the function, and the return value is the status of the call. The darkside is you get something naive like this: int err = func1(...); if (!err) { err = func2(...); if (!err) { err = func3(...); } } return err; I could macro it I suppose: #define ERR(x) if (!err) { err = (x) } int err = 0; ERR(func1(...)); ERR(func2(...)); ERR(func3(...)); return err; But that only works if I'm chaining function calls, vs doing other work. Obviously Java, C#, C++ have exceptions that work very well for these kinds of things. I'm just curious what other folks do and how other folks do error handling in their C programs nowadays.

  • F# - Function with no arguments?

    - by Rubys
    When thinking in a functional mindset, given that functions are supposed to be pure, one can conclude any function with no arguments is basically just a value. However, reallity gets in the way, and with different inputs, I might not need a certain function, and if that function is computationally expensive, I'd like to not evaluate it if it's not needed. I found a workaround, using let func _ = ... and calling it with func 1 or whatever, but that feels very non-idiomatic and confusing to the reader. This boils down to one question: In F#, Is there a proper way to declare a function with zero arguments, without having it evaluated on declaration?

  • The best approach to customize Bootstrap Less files and keep it easy to be updated to future versions

    - by user322896
    I'm wondering what the best way would be to customize the less files in Bootstrap and, at the mean time, keep it easy to be updated to future Bootstrap versions. It's straightforward to just modify the less files, but the problem is that when the next version of Bootstrap comes out, it might be painful to upgrade (because all the changes are already deeply mixed with the original sources.) Another approach would be similar to the open closed principle, that is, keeping the original less files unchanged, and adding my customized less files to overwrite the CSS rules I need. When Bootstrap gets updated, (hopefully) I can simply replace the less files and everything would work magically. However, regardless of the correctness of my assumption, the same CSS rules would be scattered in even more places and hard to manage. Also, the more we overwrite the CSS (not for compatibility or other purposes), the more bandwidth we waste. I know this highly depends on how the author of Bootstrap would handle the structure of the framework or even the naming of CSS rules, but I'd still like to hear everybody's opinions. Thanks.

  • jQuery: Fade not working

    - by Rosarch
    For some reason, jQuery's fade effect isn't working. Could it be because of the code? This function does everything it is supposed to, aside from the fading. It gets called at the correct time. function moveToTerm(original_course, helper, term) { var cloned_course = original_course.clone(true); original_course.addClass('already-scheduled'); helper.fadeOut(function() { cloned_course.appendTo(term).attr('style', '').fadeIn("slow"); }); } UPDATE: It fails in both FF 3.5.9 and IE 8.

  • Need advice on multitab form in ASP.NET MVC

    - by Sasha
    Hi all, i need an advice on how to implement my form. I have a requirement: i need a form that spans through 5 tabs. Each tab has around 10 fields, some of them empty, some of them must contain data from db and be non editable. Each of these tabs must be a part of one form that is submitted to my controller. The question is: what is the best way to implement this? I was thinking about having partial views on each tab, each view would have its own model class. After form gets filled all data from all partials would go to action that will take care of all of it. Any advices? I am using ASP.NET MVC 1, Entity Framework 1, mvc extensions from Telerik and jQuery

  • Two part form in Rails

    - by samuel02
    I have some two nested resources, so that a Product can have many Bookings. On one page in a different controller I want to create a new booking and since it's a "general" booking I want a select menu to appear in a modal window where the user is able to pick one of the existing products and then go to the booking page. How can I do this? I have no problem setting up the modal and the "New booking" page is already there. What I need is a form that generates a list of existing products, picks the selected product id and then gets /products/:product_id/bookings/new . Any help appreciated! I realize my title does not describe my problem very good so better suggestions are highly welcome!

  • Movement in game programming

    - by hanesjw
    This question may have been asked before, but I'm starting to get into game programming on the Android. I'm having a hard time figuring out the best way to move an object. To put it simply, lets say I have a bitmap located on 0,0 and i want to move it across the screen. The obvious way to do it would be to simply increment the X position by one every time the Surface View onDraw method gets called. But what if I wanted to make it move faster? I could increment it by two or three instead of one, but then the movement starts to get really choppy and stupid looking. What is the best way to go about doing this?

  • 1120: Why can't it access the variable?

    - by Oden
    I'm new at as3, maybe thats the reason why i don't understand, why the setInterval causes an error. <mx:Script> <![CDATA[ import flash.utils.setInterval; import mx.controls.Alert; [Bindable] public var MyInt:int = 500; setInterval(function():void{ ++MyInt; },1000); ]]> </mx:Script> I have a label where the value of MyInt gets visible, the bind works perfect, i've tested it several ways, and i i create a button it grows the number, but if i use the setInterval function i get an error: Access of undefined property myInt. Why? What does cause this? Please explain it, so I can avoid errors like this. Thanks

  • Rotating Viewbox contents smoothly

    - by user204562
    I'm looking to teach myself better methods of doing things in WPF that I would normally do manually. In this case, I have a ViewBox with an image in it. I also have a button that uses a DoubleAnimation to rotate the image 90 to the right. This animation works fine, but obviously because it's square as it turns, the image does a "best fit" to the ViewBox which makes the rotation look quite bad, as it gets larger and smaller as its longest edge shrinks or grows to fit to that particular rotation angle. I am looking for any advice on the best way to handle this using appropriate WPF methods. Obviously I could do all the calculations manually, but I would be more interested in finding a way to use the controls and methods built into the .NET architecture. Thanks for your help.

  • Multible jquery .load() methods not running concurrently in MVC 2

    - by Boob
    In one of my aspx pages i have something like this in the head: <script type="text/javascript"> $(function() { // Jquery stuff loadStuff(); }); function loadStuff() { $('#result1').load({ source: url }); $('#result2').load({ source: url }); $('#result3').load({ source: url }); }; </script> The idea being that as the page is being displayed these loads will populate the specified divs with results from different webservices as and when the info becomes available. My problem is that this requests are being queued and being sent one at a time. However I want these to be sent at the same time and whichever returns first gets displayed first! Also if I try to kick off another request while these divs are loading the request seems to get queued after the others. How do I make these requests concurrent instead of queued? Thanks

  • Getting confused why i dont get expected amount ?

    - by Stackfan
    I have 1 result and which i will receive in Bank account, Based on that account i have to Put a balance to user account. How can you find the Handling cost from total tried 491.50 / 0.95 = 517.36 which is wrong ? It should be 500.00 (to my expectation) User balance requires 500.00 When 500.00 selected he gets 5% discount There is a handling cost for this ex: 1) Discount: 500.00 - 5% = 475.00 2) Handling cost: (475.00 x 0.034) + 0.35 = 16.50 3) Total: 475.00 + 16.50 = 491.50 So problem is from 491.50, i have to find atleast handling cost to get promised Balance. Any solution ? Cant figure it out myself...

  • How to handle uncaught Exceptions in javascript without a try/catch-block?

    - by user344238
    What i try to accomplish is to register a global handler to catch all uncaught exceptions. Searching the web i only managed to find people pointing out window.onerror but this doesn't do the trick for me. Apparently window.onerror only gets called upon errors and not upon exceptions. Assume the following code: function windowError(message, url, line) { alert(message, url, line); } window.onerror=windowError; throw("uncaught"); The obviously uncaught exception won't trigger the windowError handler. (Using Firefox 3.6.3) Any suggestions?

  • Why is Hibernate not loading a column?

    - by B.R.
    I've got an entity with a few properties that gets used a lot in my Hibernate/GWT app. For the most part, everything works fine, but Hibernate refuses to load one of the properties. It doesn't appear in the query, despite being annotated correctly in the entity. The relevant portion of the entity: @Column(name="HasSubSlots") @Type(type="yes_no") public boolean hasSubSlotSupport() { return hasSubSlotSupport; } And the generated SQL query: Hibernate: /* load entities.DeviceModel */ select devicemode0_.DevModel as DevModel1_0_, devicemode0_.InvModelName as InvModel2_1_0_ from DeviceModels devicemode0_ where devicemode0_.DevModel=? Despite the fact that I refer to that property, it's never loaded, lazily or not, and the getter always returns false. Any ideas on how I can dig deeper into this, or what might be wrong?

  • swipe to delete uitableview cell; a bit jumpy?

    - by Veeru
    I have implemented "swipe to delete" on my table cell. It works fine, how ever, the delete button is a little jumpy; as in, i really have to position my finger on top of the button and carefully touch it to delete the record. I am not sure if am making it clear; let me do my best to explain When the delete button appears; the user has trouble clicking on it, it disappears the moment its clicked. THe user has to try a few times to actually delete the cell. Am not sure what the reason is, it just seems like the delete button gets hidden as though the user has clicked on a different part of the cell. Any suggestsions?

  • How can I update a column in a table with the result of a select statement that uses row being updat

    - by Sailing Judo
    This SQL statement example is very close to what I think I need... update table1 set value1 = x.value1 from (select value1, code from table2 where code = something) as x However, what I need to do is change the "something" in the above example to a value from the row that is being updated. For example, I tried this but it didn't work: update table1 A set value1 = x.value1 from (select value1, code from table2 where code = A.something) as x This is a one time operation to update an existing table and I'm not really looking for high performance way to do this. Any solution that gets the task done is good enough.
