  • JQuery Syntax Problem?

    - by Michael Smith
    I am using JQuery to insert divs into a page but i cant seem to get the quotation marks correctly setup. For example the code below works fine: var newDiv_1 = '<div id="event_1"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); But when i try to use variable in place of the normal text, i doesnt seem to work: var eventname = 1; var newDiv_1 = '<div id="event_' . eventName . '"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); How do i use variable inside this statement?

  • ASP.Net WebSite Membership AND C# Windows Form Membership

    - by user1638362
    This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

  • What are the differences between enterprise software/architecture patterns and open source software?

    - by Jeffrey
    I am mainly a business app developer and I hear terms like CQRS, ServiceBus, SOA, DDD, BDD, AOP a lot. My question is that do these patterns/practices exist only in the "enterprise" world? In contract to the enterprise world is the open source community. Highly trafficked sites like Digg, LiveJournal whenever there is an article mentioning about how they built/scaled their sites all I am hearing is what open source software (Memcached, NoSQL) they used in order to scale/simplify the way they tackle software problems and they rarely mention those above terms. Is it because they are not as sophisticated as those of enterprise level software (I doubt it)? Or are people just making up those terms/practices/patterns in order to keep them jobs? Or am I confusing myself with differences between software development and internet website scaling?

  • What benefits can Java developer have moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse there, so there will be no big difference. Guys, who use Java on *NIX, could you please give me a real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • .NET XML Serialization, possibly to use a different method name than PropertySpecified for ignoring

    - by Lasse V. Karlsen
    I have a bunch of classes that I intend to serialize in order to transport over a webservice call. These classes already have properties that return whether a given "real" property has a value or not, that is ingrained in a lot of code of our product. Is it possible, for instance through attributes, for me to specify that each "real" property should be included if a specified other property returns true, but not one that is called RealPropertyNameSpecified? ie. for instance if I have this class: [XmlType("test")] public class TestClass { [XmlIgnore] public bool NameHasGotAValue { get; set; } [XmlElement("name")] public string Name { get; set; } } Is it possible for me to use the NameHasGotAValue as the "*Specified" method for the Name property, or is my only option to either rename NameHasGotAValue, add a NameSpecified method, or implement IXmlSerializable?

  • How does one search/poll all modal info in a frame automatically?

    - by user310631
    As you'll no-doubt be able to tell momentarily, I have little knowledge of the programming world. That being said, here goes.... In this scenario, there's a Java-based game that has a map of the game world oriented in an X, Y coordinate tile system. Some of the grid tiles are player cities, some are non-player locations. The game runs inside a frame in the browser, the X, Y coordinate map feature is one optional view, and the entire map is not available to view at any one time. Each grid tile has an "Onclick" event and an "Onmouseover" event. The mouseover event is a tooltip, the click event is something called a "modal" that has information specific to that tile. What I'd like to find out is: How can I poll all the grid tiles' "modal" information using some kind of script or other auto-running polling feature?

  • Facebook Open Graph without a browser

    - by Hellnar
    Hello, For a middleware system with internet (which works inside a set-top box) I want to develop a primitive Facebook interface where users can type their user-names and password, showing their latest notification, messages and other casual stuff on the TV screen by using the recent Facebook Graph API. This middleware program uses Java ME to run programs (such as this simple facebook app) and it can connect to internet however it doesn't have a real web browser. Without browser it can connect to any url to retrieve the JSON response however I am not sure how to achieve authentication without a real browser. Under this circumstances, is it possible Facebook authentication? If you think so, what approach would you suggest ? Thanks

  • Why is it bad practice to use links with the javascript: "protocol"?

    - by zneak
    Hello everyone, In the 1990s, there was a fashion to put Javascript code directly into <a> href attributes, like this: <a href="javascript:alert('Hello world!')">Press me!</a> And then suddenly I stopped to see it. They were all replaced by things like: <a href="#" onclick="alert('Hello world!')">Press me!</a> For a link whose sole purpose is to trigger Javascript code, and has no real href target, why is it encouraged to use the onclick property instead of the href property?

  • Dynamically sized panels

    - by codemnky
    I have a dynamically created tabpage for windows forms. the tabpage is split into two horizontal panels. The top panel should be able to hold up to 4 textboxes like this TextBox1 TextBox2 TextBox3 TextBox4 There WILL be atleast one TextBox. Maximum is 4. How do I create a TabPage with two panels where the top panel only takes up the real estate as needed(i.e only use up the real estate for one textbox or 2 textboxes, or 3 textboxes or the maximum 4 textboxes) and the rest of the tabpage is available for Panel2.

  • Python:How to override inner class methods if the inner class is defined as a property of the top cl

    - by Maddy
    I have a code snippet like this class A(object): class b: def print_hello(self): print "Hello world" b = property(b) And I want to override the inner class 'b'(please dont worry about the lowercase name) behaviour. Say, I want to add a new method or I want to change an existing method, like: class C(A): class b(A.b): def print_hello(self): print "Inner Class: Hello world" b = property(b) Now if I create C's object as c = C(), and call c.b I get TypeError: 'property' object is not callable error. How would I get pass this and call print_hello of the extended inner class? Disclaimer: I dont want to change the code for A class.

  • C++ conditional compilation

    - by Shaown
    I have the following code snippet #ifdef DO_LOG #define log(p) record(p) #else #define log(p) #endif void record(char *data){ ..... ..... } Now if I call log("hello world") in my code and DO_LOG isn't defined, will the line be compiled, in other words will it eat up the memory for the string "hello world"? P.S. There are a lot of record calls in the program and it is memory sensitive, so is there any other way to conditionally compile so that it only depends on the #define DO_LOG? Thanks in advance.

  • Regular expression match, extracting only wanted segments of string

    - by Ben Carey
    I am trying to extract three segments from a string. As I am not particularly good with regular expressions, I think what I have done could probably be done better... I would like to extract the bold parts of the following string: SOMETEXT: ANYTHING_HERE (Old=ANYTHING_HERE, New=ANYTHING_HERE) Some examples could be: ABC: Some_Field (Old=,New=123) ABC: Some_Field (Old=ABCde,New=1234) ABC: Some_Field (Old=Hello World,New=Bye Bye World) So the above would return the following matches: $matches[0] = 'Some_Field'; $matches[1] = ''; $matches[2] = '123'; So far I have the following code: preg_match_all('/^([a-z]*\:(\s?)+)(.+)(\s?)+\(old=(.+)\,(\s?)+new=(.+)\)/i',$string,$matches); The issue with the above is that it returns a match for each separate segment of the string. I do not know how to ensure the string is the correct format using a regular expression without catching and storing the match if that makes sense? So, my question, if not already clear, how I can retrieve just the segments that I want from the above string?

  • XNA 2d camera with arbitrary zoom center

    - by blooop
    I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

  • debugfs_create_file doesn't create file

    - by bala1486
    Hello, I am trying to create a debugfs file using the debugfs_create_file(...). I have written a sample code for this. static int __init mmapexample_module_init(void) { file1 = debugfs_create_file("mmap_example", 0644, NULL, NULL, &my_fops)\ ; printk(KERN_ALERT "Hello, World\n"); if(file1==NULL) { printk(KERN_ALERT "Error occured\n"); } if(file1==-ENODEV) { printk(KERN_ALERT "ENODEV occured\n"); } return 0; } When i ran insmod i could get the Hello, World message but no the error message. So i think the debugfs_create_file worked fine. However i couldn't find any file in /sys/kernel/debug. The folder is there but it is empty. Can anyone help me with this? Thank you... Thanks, Bala

  • basic json > struct question

    - by danwoods
    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

  • Best Practices & Considerations when writing HTML Emails

    - by Jonathan Sampson
    I've been developing websites for over a decade now, but quickly found that many of my habits in developing for the web are useless when developing for email clients. This has caused me an enormous amount of frustration, so I thought I would ask a question that would hopefully surface the best practices and necessary considerations for others like myself who may find themselves designing for gmail, outlook, etc. from time to time. Example: <style>...</style> vs inline CSS. In short: what transfers over from the web-world to the email-world, and what doesn't.

  • Database triggers / referential integrity and in-memory caching

    - by Ran Biron
    Do you see database triggers / referential integrity rules being used in a way that changes actual data in the database (changing row w in table x causes a change in row y in table z)? If yes, How does this tie-in with the increasing popularity of in-memory caching (memcache and friends)? After all, these actions occur inside the database but the caching system must be aware of them in order to reflect to correct state (or at least invalidate the possibly changed state). I find it hard to believe that callbacks are implemented for such cases. Does anyone have real-world experience with such a setup / real-world experience with considering such a setup and abandoning it (which way did you go? if caching, how do you enforce integrity?)

  • What is the best API in any language for Audio and MIDI music application development?

    - by noneme
    What, in your opinion, is the best API to utilize in developing an application that handles both realtime MIDI and audio input and output? This would be for an application that is used in the process of making music as opposed to playing audio or MIDI files. I'm aware that this may be a subjective question, but if you know of an API that is dominantly used for these purposes, please share it. I'm agnostic about which language the API is for, and I also don't care about portability. The real concern is for an API that is well documented, well designed (e.g. thought out and intuitive to developers using it), and actively maintained. OS portability would be nice, but it is second to having an API/Language that meets the previous requirements. Please note that the emphasis is not on API's for sound synthesis or for composing music with code. It is intended for the handling of sound file and MIDI data in a real-time context.
