  • Send JSON object via GET and POST without having to wrapping it in another object literal, and manag

    - by Kucebe
    My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'person' : person}. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['person'] or $_POST['person']. For example: var person = { 'name' : 'John', 'lastName' : 'Doe', 'age' : 32, 'married' : true } sendAjaxRequest(person); in php, using: $person = json_decode(file_get_contents("php://input")); i can get easily the object, but only with POST format, not in GET. Any suggestions?

  • Write Local File using Adobe Air Iframe

    - by user290687
    This is driving me mad. I am creating an AIR application and everything is working great. However I would really like to have a form inside an Iframe that when the user clicks submit saves the file to local application storage directory. Right now I am able to do this and save the file with no problems when I just access the HTML page not inside an Iframe. However if I wrap the page in an iframe and hit submit the file does not save. Any code examples would be very much appreciated. When I am using the iframe my code looks as follows<iframe src="jobs/newjob.html" height="800px" width="800px" sandboxRoot="app:/" documentRoot="app:/sandbox"ondominitialize="setupBridge ()">

  • In C# how can I serialize a List<int> to a byte[] in order to store it in a DB field?

    - by Matt
    In C# how can I serialize a List to a byte[] in order to store it in a DB field? I know how to serialize to a file on the disk, but how do I just serialize to a variable? Here is how I serialized to the disk: List<int> l = IenumerableofInts.ToList(); Stream s = File.OpenWrite("file.bin"); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(s, lR); s.Close(); I'm sure it's much the same but I just can't wrap my head around it.

  • Creating an interface and swappable implementations in python

    - by Blankman
    Hi, Would it be possible to create a class interface in python and various implementations of the interface. Example: I want to create a class for pop3 access (and all methods etc.). If I go with a commercial component, I want to wrap it to adhere to a contract. In the future, if I want to use another component or code my own, I want to be able to swap things out and not have things very tightly coupled. Possible? I'm new to python.

  • Is there a Java 1.5 varargs API for slf4j yet?

    - by Josh
    I want to get rid of this lot... public void info(String msg); public void info(String format, Object arg); public void info(String format, Object arg1, Object arg2); public void info(String format, Object[] argArray); ...and replace it with this one... public void info(String format, Object ... args); ...so that my logging syntax doesn't have to change depending on the number of arguments I want to log. There seems to be lots of discussion and work around it, but where is it? Or should I wrap the wrapper that is slf4j?

  • HttpTunneling a TCPClient application

    - by user360116
    We have a custom chat application(c#) which uses TCPClient. We are having problem on clients who are behind Firewall or proxy. We know that these client can browse the internet without a problem so we decided to change our TCPClient application so that It uses HTTP messages to communicate. Will it be enough just to wrap our text massages with standard HTML tags and HTTP headers? We need a long lasting connection. Does keep-alive have a limit? Do firewalls or proxies have time limits for "alive" connections.

  • Online Game programming in Google App Engine: AI

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players(you can probably guess the type of game im developing)

  • How can I resolve naming conflict in given precompiled libraries?

    - by asm
    I'm linking two different libraries that have functions with exactly same name (it's opengl32.lib and libgles_cm.lib - OpenGL ES emulation under Win32 platform), and I want to be able to specify, which version I'm calling. I'm porting a game to OpenGL ES, and what I want to achieve, is a split-screen rendering, where left side is an OpenGL version, and right side is a ES version. To produce the same result, they will recieve slightly different calls, and I'll be able to visually compare them, effectively finding visual artifacts. It worked perfectly with OpenGL/DirectX at the same window, but now the problem is that both versions imports the functions with the same name, like glDrawArrays, and only one version is imported. Unfortunately, I don't have sources of any of that libraries. Is there a way to... I dont' know, wrap one library into additional namespace before linking (with calls like ES::glDrawArrays), somehow rename some of functions or do anything else? I'm using microsoft compiler now, but if there will be solution with another one (GCC/ICC), I'll switch to it.

  • improve my jquery validation plugin code

    - by Jared
    Hi All Just hoping soemone can help me to write better code than I can come up with on my own. I am using the jquery validation plugin. I have some fields that are mandatory ONLY if certain options are chosen. The below code works fine. But the thing is, is that that my list of 'OR's is much longer than I've put here. and it needs to be applied not just to 'directorsName' but a whole long list of inputs, selects etc. My question is.. how can I wrap up the code contained inside the RETURN? (so I dont have to keep repeating my 'OR's. I'm guessign I need a function but I'm unsure of the syntax) $("#myForm").validate({ rules: { directorsName : { required: function(element) { return ( $('#account_for').val() == "Joint" || $('#directors_number').val() == "2" || $('#directors_number').val() == "3" ); } } } }); Thanks in advance

  • Two way binding when setter is overriden

    - by Nicolas Goy
    I have an NSTextField bound to some object "zoom" property. In this object's class implementation, I have the following - (void)setZoom:(CGFloat)zoom { _zoom = MAX(0, MIN(10, zoom)); } If I write "-5" in the textfield, setZoom: will be called with "-5" as argument and _zoom will be set to 0. Then problem is that the textfield is not updating itself and it shows "-5" instead of re-reading the property value it has just set. If I do myObject.zoom = -5; in code, the text field will display 0 correctly. I tried to wrap _zoom =... inside willChangeValueForKey/didChangeValueForKey calls but it didn't change anything.

  • I'm having a hard time wrapping my head around handling the Activity Lifecycle...

    - by kefs
    So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

  • Using generics in dotnet for functions with any number of arguments?

    - by Zarigani
    I would like to have a function that can "wrap" any other function call. In this particular case, it would allow me to write some more generic transaction handling around some specific operations. I can write this for any particular number of arguments, e.g. for one argument: Public Shared Sub WrapFunc(Of T)(ByVal f As Action(Of T), ByVal arg As T) ' Test some stuff, start transaction f(arg) ' Test some stuff, end transaction End Sub ... but I was hoping to have this handle any number of arguments without having to have duplicate code for 0 args, 1 arg, 2 args, etc. Is there a way of doing this?

  • What's the best way to implement a dynamic proxy in C#?

    - by gap
    Hi, I've got a need to create a dynamic proxy in C#. I want this class to wrap another class, and take on it's public interface, forwarding calls for those functions: class MyRootClass { public virtual void Foo() { Console.Out.WriteLine("Foo!"); } } interface ISecondaryInterface { void Bar(); } class Wrapper<T> : ISecondaryInterface where T: MyRootClass { public Wrapper(T otherObj) { } public void Bar() { Console.Out.WriteLine("Bar!"); } } Here's how I want to use it: Wrapper<MyRootClass> wrappedObj = new Wrapper<MyRootClass>(new MyRootClass()); wrappedObj.Bar(); wrappedObj.Foo(); to produce: Bar! Foo! Any ideas? What's the easiest way to do this? What's the best way to do this? Thanks so much.

  • Connecting two DialogBoxes in GWT

    - by Apophenia Overload
    In my GWT project, I'm trying to get it so two DialogBoxes can pass information between each other. One of them holds a MapWidget, and when a button is pressed in the other DialogBox, the position information is received from that other DialogBox's MapWidget. Does anyone have any tips for how I should coordinate between having two different DialogBoxes show up? Should I wrap the code for the two in a Composite? Furthermore, is there an example anywhere of dealing with two DialogBoxes at once in GWT? For example, if I click outside of the two boxes, both should be dismissed. I'm wondering if there's a way to keep both of them in focus at once, so I can switch between the two without causing either to disappear.

  • Python Textwrap - forcing 'hard' breaks

    - by Tom Werner
    I am trying to use textwrap to format an import file that is quite particular in how it is formatted. Basically, it is as follows (line length shortened for simplicity): abcdef <- Ok line abcdef ghijk <- Note leading space to indicate wrapped line lm Now, I have got code to work as follows: wrapper = TextWrapper(width=80, subsequent_indent=' ', break_long_words=True, break_on_hyphens=False) for l in lines: wrapline=wrapper.wrap(l) This works nearly perfectly, however, the text wrapping code doesn't do a hard break at the 80 character mark, it tries to be smart and break on a space (at approx 20 chars in). I have got round this by replacing all spaces in the string list with a unique character (#), wrapping them and then removing the character, but surely there must be a cleaner way? N.B Any possible answers need to work on Python 2.4 - sorry!

  • What is the fastest method to calculate substring

    - by Misha Moroshko
    I have a huge "binary" string, like: 1110 0010 1000 1111 0000 1100 1010 0111.... It's length is 0 modulo 4, and may reach 500,000. I have also a corresponding array: {14, 2, 8, 15, 0, 12, 10, 7, ...} (every number in the array corresponds to 4 bits in the string) Given this string, this array, and a number N, I need to calculate the following substring string.substr(4*N, 4), i.e.: for N=0 the result should be 1110 for N=1 the result should be 0010 I need to perform this task many many times, and my question is what would be the fastest method to calculate this substring ? One method is to calculate the substring straight forward: string.substr(4*N, 4). I'm afraid this one is not efficient for such huge strings. Another method is to use array[N].toString(2) and then wrap the result with zeros if needed. I'm not sure how fast is this. May be you have any other ideas ?

  • Java Custom exception throw behaves differently between different Projects

    - by Pablo
    I am attempting to call the following in my code: public void checkParticleLightRestriction(Particle parent) throws LightException { if ( parent == null ) { throw new LightException("quantum-particle-restrict.23", this); } In one Project the exception is thrown and the effect is similar to calling "return" whereby I am returned back to the point immediately succeeding where this method was called. However in another Project I get thrown completed out of the current package and to a point way prior to the point preceeding this method. It likes instead of being kicked out of a bar I am being deported all the way out of the country. My option are the wrap the throw in a try / catch but I am wondering why this difference in behaviour beween the 2 projects ?

  • Is there a way to cut and paste or clone CSS from one element to another using JQuery?

    - by Jared Christensen
    I have a situation where I'm wrapping an image with a span and I want to remove all the CSS from the image and apply it to the span. Is there a way to do this with JQuery? JQuery: $(img).wrap('<span />'); Style Sheet: img { border: 5px solid red; padding: 10px; … } I would like do to do this with out editing the HTML or CSS. For example adding a class to the image would not work very well in my situation. I need a way to truly remove the CSS from one element and place it on another.

  • tmux: create session if none exists

    - by rampion
    I'm switching from using gnu-screen to tmux, and I'm still trying to wrap my head around changes. One thing I'd like to be able to do is start tmux and have it automatically connect to a session if one exists, and otherwise create a new session. tmux attach attaches to an automatically existing session - but errors out if no session exists tmux new creates a new session - but it does so every time, so I can't leave it in my .tmux.conf tmux has-session tests whether a session exists - but I don't know how to stitch it together with the other commands Can anyone give me some configure file advice?

  • How can I not render a button in my view if a given property off my model has no value?

    - by Lee Warner
    I'm new to web development. In my view, I want to conditionally show a button if Model.TemplateLocation (which is a string) is not null or empty. Below is the code that is rendering the button currently: <div class="WPButton MyButton"> <%=Html.ActionLink(Model.TemplateLinkName, "DownloadTemplate", "ExternalData", new ArgsDownloadTemplate { Path = Model.TemplateLocation, FileName = Model.TemplateFileNameForDownload }, new{})%> </div> Can I wrap some C# code in the <% %'s to test for Model.TemplateLocations value before I render that? I was told to look into @style = "display:none" somehow. Could that be what I need?

  • jQuery: what is it "forbidden" to do in plain Javascript

    - by flybywire
    A jQuery best practices question. I am writing a very jQuery intensive web page. I am new to jQuery and notice its power, but as I come with heavy javascript experience and knowledge, my question is: What should be done in jQuery and what in plain javascript. For example, there are callbacks that send a plain DOM object as an argument. Should I use that or should I wrap it ( like $(this)). Does it matter if I do this.x=y or $(this).attr("x", y).

  • How do I deal with connection strings in a Click-Once application?

    - by Pwninstein
    I'm thinking of building a Click-Once application, and am trying to wrap my head around how to handle the whole connection string issue. The problem is the following: I want to use EF to get data directly from each client, thus requiring each client to have a connection string configured (this is not the issue). How do I deal with clients that are not on the same domain as the SQL Server being queried? In other words, if I tried to run my app from home as opposed to from work, what should my connection string look like? Would I need to configure my SQL Server differently to allow this scenario? Thanks in advance!

  • iOS Development: Why isn't my try block catching the exception?

    - by BeachRunnerJoe
    Hi. I have an exception being thrown in my code, but when I wrap it in an try/catch block, it doesn't get caught. The NSLog statement is never called in the catch block. Here's the code... NSInteger quoteLength; [data getBytes:(void *)&quoteLength range:NSMakeRange(sizeof(messageType), sizeof(quoteLength))]; @try { //Debugger stack trace shows an NSException being thrown on this statement NSData *stringData = [data subdataWithRange:NSMakeRange(sizeof(messageType) + sizeof(quoteLength), [data length])]; NSString *quote = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding]; NSLog(@"received quote: %@",quote); [quote release]; } @catch (NSException * e) { NSLog(@"Exception Raised: %@", [e reason]); } Why doesn't it get caught? Thanks so much!

  • Delegates vs. events in Cocoa

    - by aaronstacy
    I'm writing my first iPhone app, and I've been exploring the design patterns in Cocoa and Objective-C. I come from a background of client-side web development, so I'm trying to wrap my head around delegates. Specifically, I don't see why delegate objects are needed instead of event handlers. For instance, when the user presses a button, it is handled with an event (UITouchUpInside), but when the user finishes inputting to a text box and closes it with the 'Done' button, the action is handled by calling a method on the text box's delegate (textFieldShouldReturn). Why use a delegate method instead of an event? I also notice this in the view controller with the viewDidLoad method. Why not just use events?

  • WPF: Bind DataGrid to List<String>

    - by Sam
    Funny, how sometimes the simple things bite me in the behind. I can bind a DataGrid nicely to a Collection of some arbitrary class, using a DataGridTextColumn like this: <DataGridTextColumn Header="Name" Binding="{Binding Name}"/> Now I want to bind a DataGrid to a simple Collection. So since there is no property "Name" or something like that to bind to, how do I write the binding: <DataGridTextColumn Header="Name" Binding="{Binding ???}"/> String has no Property "Value" or something like that. And if I just write {Binding } I'll end up with a one-way-binding, unable to write changes back to the Collection. Thinking about it, I think it is not possible to bind to a collection, so I do need to wrap my string into a class? Or is there a way?
