  • Best practice when working with web services that return objects?

    - by Raj
    Hello, I'm currently working with web services that return objects such as a list of files e.g. File array. I wanted to know whether its best practice to bind this type of object directly to my front end code for example a repeater/listview or whether to first parse it into my own list of "file class" e.g. customFiles[] If the web service changes then it will break my front end code, however if I create my own CustomFile class, then i would only need to change my code in one place to fix the issue, but it just seems like a lot of extra work to create the same classes from a web service, i wanted to know what is the best practice for this type of work. thanks Raj.

  • Why are my JavaScript variables not persisting across functions?

    - by Eric Belair
    I have the following JavaScript in my HTML page referencing an HTML form on the page: <script type="text/javascript"> <!-- var myForm = document.myForm; function validateForm() { if (myForm.myInput == "") alert("Please input some text."); return false; } myForm.submit(); } function showFormInput() { myForm.reset(); document.getElementById('myInput').style.display = 'inline'; } //--> </script> ... <form name="myForm" id="myForm" action="..." method="post"> <input id="myInput" name="myInput" type="text" value="" style="display:none;" /> </form> Both functions are throwing an exception when trying to access the variable myForm, saying that "myForm is null or not an object". Why is this occurring?

  • Why jQuery selector can't work but getElementById works in this scenario?

    - by Stallman
    Here is the HTML: <html> <head> <script type="text/javascript" src="jquery-1.7.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="jquery-1.7.2.js"></script> <script type="text/javascript" src="access.js"></script> </head> <body> <button id="trigger"></button> <img id= "testElement" style= "position: absolute; border-color: white; top:340px; left:615px;" width="34px" height= "34px" /> </body> </html> And the access.js file is: $(document).ready( function(){ $('#trigger').click(function(){ $('#testElement').src="success.png"; //THIS WON'T WORK. document.getElementById('testElement').src= "success.png"; //BUT THIS WORKS. }); }); I know that if I use $, the return object is a jQuery object. It's not the same as getElementById. But why the jQuery selector can't work here? I need the jQuery object to make more operations like "append/style"... Thanks. UPDATE Too much correct answers appear at almost the same time... Please give more explanations to let me decide who I should give the credit, thanks!!! Sorry for my poor understanding of your correct answer... I just want more detail. Are all the attribute nodes(src/width/height...) not the property of jQuery object? So does the jQuery selector only select DOM Element Node like ? Thank you! 3. List item

  • mapping list of different types implementing same function?

    - by sisif
    I want to apply a function to every element in a list (map) but the elements may have different types but all implement the same function (here "putOut") like an interface. However I cannot create a list of this "interface" type (here "Outputable"). How do I map a list of different types implementing the same function? main :: IO () main = do map putOut lst putStrLn "end" where lst :: [Outputable] -- ERROR: Class "Outputable" used as a type lst = [(Out1 1),(Out2 1 2)] class Outputable a where putOut :: a -> IO () -- user defined: data Out1 = Out1 Int deriving (Show) data Out2 = Out2 Int deriving (Show) instance Outputable Out1 where putOut out1 = putStrLn $ show out1 instance Outputable Out2 where putOut out2 = putStrLn $ show out2 I cannot define it this way: data Out = Out1 Int | Out2 Int Int putOut Out1 = ... putOut Out2 = ... because this is a library and users should be able to extend Out with their own types

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • jquery background image fade

    - by Nick
    I am using jQuery to load ina background image that fills the page width / height. I have the following in the Head: $(document).ready(function() { $('body').css({ 'background-image' : 'url({HTML_BASE}images/backgrounds/randoms/{BACK_IMG})', 'background-repeat' : 'no-repeat', 'background-position' : 'center top', 'background-attachment': 'fixed', 'background-size': '100% 100%', }); $('#home-promo').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: 'auto' }); $('.model-search').innerfade({ speed: 'slow', timeout: 5000, type: 'sequence', containerheight: '393' }); }); This works fine and can be seen at http://projects.snowshtechnologies.com/golden_dragon/home/ I want the BG image to fade in from the black background colour. I have looked at a few other threads on Stack that suggest its not possible as a body element defined in css, but in this scenario the BG image is being loaded in by jQuery. How would I go about adding a fade in to this code to bring the image in with a nice fadein?

  • What is the correct method to load an XML file and re-write it as a CVS? (C# Only)

    - by codesmack
    Hello, I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named and within the car element I need to process the element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C# Thank you, CodeSmack

  • Returning pointer to a certain value in a macro?

    - by Andrei Ciobanu
    Is it possible to write a macro that has a type and a value as its input parameters (MACRO(type,value)), and returns a valid pointer to a location that holds the submitted value. This macro should perform like the following function, but in a more generic manner: int *val_to_ptr(int val){ int *r = NULL; r = nm_malloc(sizeof(*r)); *r = val; return r; } Where nm_malloc() is a failsafe malloc. The Macro usage should be compatible with this usage: printf("%d",*MACRO(int,5)); Is it possible to achieve that ?

  • PreparedStatement and setTimestamp in oracle jdbc

    - by Roman
    Hi everyone, I am using PreparedStatement with Timestamp in where clause: PreparedStatement s=c.prepareStatement("select utctimestamp from t where utctimestamp>=? and utctimestamp<?"); s.setTimestamp(1, new Timestamp(1273017600000L)); //2010-05-05 00:00 GMT s.setTimestamp(2, new Timestamp(1273104000000L)); //2010-05-06 00:00 GMT The result I get is different, when I have different time zones on the client computer. Is this a bug in Oracle jdbc? or correct behavior? The parameter is Timestamp, and I expected that no time conversions will be done on the way. The database column type is DATE, but I also checked it with TIMESTAMP column type with the same results. Is there a way to achieve correct result? I cannot change default timezone in the the whole application to UTC. Thanks for your help

    I have a HTML form that is sometimes submitted with accented characters: à, è, ì, ò, ù I have a PHP script that exports these form submissions into CSV format, when I look at the CSV format in a text editor (vim or notepad for example) the characters look fine, but when opened with Open Office or Word, I get some funky results: ????? I am also passing these submission to salesforce and am getting an error: "The entity "Atilde" was referenced, but not declared." What can I do to ensure portability of my CSV file? What's the proper way to handle the encoding? My HTML file is content-type is set as: Content-Type: text/html; charset=utf-8 Data is being stored in MySQL as latin1_swedish_ci collation.

  • What technology should I use for a complex report?

    - by SeaDrive
    I have a task to generate reports from a Visual Studio C# application. This is a replacement (caused by new requirements) for a program written using the built-in implementation of Crystal Reports. Although workable, it was far from ideal. The reports have conditional content (If type=1, print this, if type=2 print that.) Crystal does not adjust spacing dynamically and the various pieces were not the same length making for some unprofessional-looking spacing. I had thought of generating the reports in HTML, which would be feasible, but I'm concerned that you lose a degree of control, and I may be asked, e.g. to "move this up a bit" or similar which may be tricky. I'm not either a Crystal guru or an HTML guru. What other reporting technologies are available that would make it easy to drop in parts of different sizes, do table layouts, etc.?

  • C# Why does calling an interface member from a class generate an error?

    - by Jack
    So I have an interface: interface IFoo { int Bar(); int this[int i] {get; set;} } And a class that derives from it class Foo : IFoo { public int IFoo.Bar() { //Implementation { public int IFoo.this[int i] { //Implementation } } Now, I try to do this: var fooey = new Foo(); int i = Fooey.Bar(); or this: int i = Fooey[4]; I would expect these to work properly. However, the compiler generates an error as if such members don't exist. Why is that? I am aware I can cast Foo as IFoo, but I am also aware that casting is costly to performance, which is often the reason to use interfaces in the first place. EDIT 1: These are the errors generated 'Foo' does not contain a definition for 'Bar' and no extension method 'Bar' accepting a first argument of type 'Foo' could be found (are you missing a using directive or an assembly reference?) "Cannot apply indexing to an expression of type 'Foo'"

  • ASP.NET in VS IDE gives "Expression cannot be evaluated at this time."

    - by S Nash
    I read all of similar questions in SO but none seem to be an answer. Situation is simple. I have a ASP.NET webpage, In a VB code behind file I have the following line: iRendProvider = ddlProvider.SelectedItem.Value where iRendProvider is integer and ddlProvider is a dropdownlist. I put a breakpoint at the above line and code stops there. Now in the immdediate window in I type: ? ddlProvider.SelectedItem.Value I get "Expression cannot be evaluated at this time." If I step over iRendProvider = ddlProvider.SelectedItem.Value To the next line and I type ? iRendProvider , I see the correct value in the immediate window. Question is why this error and how to see contents of ddlProvider.

  • jQuery $.post & $.append & IE6

    - by Jim
    I'm having a weird problem with jQuery and IE6. Script works on IE7+ and with all other browsers I have tried it. I can't post the full script, but what it does is this: $.post("file.php",{'foo':'bar'},function(data){ $('#target').append(data) }) When I run the code in IE6, #target just shows ? and a white char with a hole in the middle. I have no idea what this second char is. My initial thought was that this was some sort of content-type problem because the file.php just echoes answer without any header information. I added Content-type: text/html with header() but didn't help. Any suggestions?
