  • Scaffolding Web Services in Grails

    - by Dan
    I need to implement a web app, but instead of using relational database I need to use different SOAP Web Services as a back-end. An important part of application only calls web services and displays the result. Since Web Services are clearly defined in form of Operation: In parameters and Return Type it seems to me that basic GUI could be easily constructed just like in the case of scaffolding based on Domain Entities. For example in case of SearchProducts web service operation I need to enter search parameters as input, so the search page can be constructed. Operation will return a list of products, so I need a page that will display this list in some kind of table. Is there already some library in grails that let you achieve this. If not, how would you go about creating one?

  • Recovering the deleted data from Android SD Card ?

    - by Nish
    I am trying to make an Android application which would try to recover deleted content from the SD Card. How feasible it is ? I have following method in mind: 1) Since, the files are not actually deleted, can I access the file system to see files which has been marked to be overwritten. 2) Or will I have do header/footer file carving ? Is it possible from the application layer of android ? I am concerned about files stored on contiguous sectors and not the fragmented once. I want to do a basic file retrieval. Please let me know some resources which I can use to make this application ?

  • Bind multiple request parameters to one object in Spring 3

    - by Max
    Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

  • Paint java GUI component to image file

    - by Simon
    Let's say I have JButton test = new JButton("Test Button"); and I want to draw the button into an image object and save it to a file. I tried this: BufferedImage b = new BufferedImage(500, 500, BufferedImage.TYPE_INT_ARGB); test.paint(b.createGraphics()); File output = new File("C:\\screenie.png"); try { ImageIO.write(b, "png", output); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } This code produced an empty 500x500 PNG-file. Does anyone know how I can draw the GUI component to an image file?

  • Assembly stack persistency

    - by user246100
    Hello. I would like to know if after calling functions the data I have in the stack is persistent. Like, I would like to know if (assuming cdecl convention) can I do this (independently of function X and independently of optimizations): push 1 push 2 push 3 call X call X call X add 12 esp ? Also, let's say that before the calls I save the address of where the pushed values are in a global variable. Can I, inside X, alter the values it contain by acessing the global variable? Like, for some reason I want that in X I'm able to alter the values in stack so that the second and third call to X receive different values.

  • Can I make a folder writeable in Medium trust?

    - by harpo
    My web app writes to several folders (logs, uploads, etc), and I've always set these permissions manually through my hosting provider. I'd like to create a setup script that performs this on new installations. Is this possible under Medium trust? I can't even call File.GetAccessControl, let alone File.SetAccessControl, but I don't need such a "big hammer", anyway. I just want to do what the ISP (in this case GoDaddy) is letting me do through a management console. I believe PHP is able to do this, and I'd be willing to consider a PHP page for this purpose if that's possible.

  • C, Cygwin, and compiling drand and srand

    - by Kaytiana
    Hello, I have a C code which I am trying to compile in Cygwin and which contains both the drand() and srand() functions. I had Windows Vista with Cygwin installed and the code seemed to comile fine, but my computer broke and I had to get a new one. The new computer has Windows 7 64-bit version. I had a few issues downloading Cygwin but finally managed to do it by only selecting a few packages and then have been trying to get the rest that I need. The problem is I don't have the help I had installing it on my other computer so I don't know which packages I actually need, so I have just been guessing (all the gcc ones) but I mustn't have the one I need for srand and drand to work. If anyone could point me in the right direction, and also possibly just let me know which packages I need to compile C so I can check I have them all that would be great. Thanks a lot in advance for any help. Sorry, that was a lot of words! Kaytiana

  • Looking for design/architecture suggestions for a simple HTML game.

    - by z-boss
    Imagine that HTML page is a game surface (see picture). User can have n number of boards (blue divs) on his page. Each board can be moved, re-sized, relabeled, created new and removed. Inside each board there are m number of figures (purple divs). Each of these user can move inside the board or to another board, re-size, change color and label, delete, add new. The goal of the game is not important, but let's say it is to rearrange figures in a certain way so that they disappear. But the goal of the programmer is to save the whole game surface in the database for every user of the site, and to load it later when he returns. So, how do I go about data exchange between client and the database? I'll give my idea in one of the answers.

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

  • Does there exist an "idea checkout system" on the Internet?

    - by TimeSpace Traveller
    Greetings. I would like to ask the following question: is there anything on the Internet like an "idea checkout" system? Situation: I'm a software developer. Since my current job has started 2 years ago, my mentor at that time has pointed me to the open source world. I have only put little time to look at some of the open source projects, let alone any contribution. However, it is my wish to start developing something outside of the work. Well, except a little problem. I don't know what to develop! It is not about the technical knowledge; the problem is that, I am not a creative person. I am very good at analytical thinking, as well as debugging skills. When being told by my work partners to develop a solution, I could get it done without a problem. However, outside of work, I have no idea what to develop. When I look at the Internet, it seems that so many people have already been developing on so many interesting stuff, making me wonder what I could develop, so that I would not reinvent something already existed. That starts to make me wonder. On the Internet, is there anything like an "idea checkout" system or society? For example, some people would throw in as a software idea, and the system would keep it as an "inventory"; later, a potential software developer would "check out" the idea, just a how people would check out a book from the library. Then, the developer would check the "idea" back in, with a certain kind of work-in-progress or developed software, thus becoming an open-source project. I have just noticed that here at stackoverflow, there is a "Project-Ideas" tag, so perhaps that can provide me some ideas on what to develop; still, my wonder is about a system that people would provide ideas, and people would check out ideas to develop / implement into actual solution. Is there such a system or society existing anywhere on the Internet? Any input is welcome! Thank you very much. Update: Thank you for everyone who has answered my question. Certainly, "getting idea" is part of my problem; as a software developer, however, I'm concerned more than just "getting idea". What I am concerned more, as I have commented, is about the existence of such an idea exchanging ecosystem, capable to initiate open-source projects. I'll put an example here. Say, person A has an idea of music search program, but not search by the attributes of the music (composer, singer, publisher, lyrics, etc.); instead, he wants a program (and a database) to search a piece of music by melody. Very often, people only remember a piece of music by its melody, not even the name of the music (e.g. the music he wants was only once heard in a bookstore, but the melody just gets stuck in his head!). In order to find that piece, normally he would just need to blindly search for it, and spent a long time to do so. A search by melody would enable person A to find the piece much quicker. However, he would not want to personally work on it, not just because of the complexity (he is not a musician and/or programmer, knowing almost nothing about music systems in computer, search algorithms, etc.), but also legal issues (RIAA??), thus he would just like to keep the idea at some place, and let other people to work on that. Now, a developer (person B) may be at the same stage as I am right now, wishing to find something to develop, but not having an idea. With the idea exchanging ecosystem, person B will search, and somehow discover person A's music search idea, and feeling interested enough to work on it. So he "checks out" the idea, start working on it (at least a skeleton), and checks back in with the progress. An open-source project starts from here, fulfilling person A's wish, and person B's programming desire. The above is just an example, because there are already such systems exist on the Internet, but it illustrates what I think about the idea exchange system in my mind. My main concern is about idea exchanging ecosystem, not at personal and unorganized level, but at a semi-organized protocol that's specifically for software developers, having actual projects coming out as the fruits. Not about "projects", but about "ideas and product of ideas". Hopefully that would clear up some of the original idea of this question. Any input is welcome; in fact, I would like to hear as many people as possible how everyone thinks about this. Thank you very much!

  • Will pool the connection help threading in sqlite (and how)?

    - by mamcx
    I currently use a singleton to acces my database (see related question) but now when try to add some background processing everything fall apart. I read the sqlite docs and found that sqlite could work thread-safe, but each thread must have their own db connection. I try using egodatabase that promise a sqlite wrapper with thread safety but is very buggy, so I return to my old FMDB library I start to see how use it in multi-thread way. Because I have all code with the idea of singleton, change everything will be expensive (and a lot of open/close connections could become slow), so I wonder if, as the sqlite docs hint, build a pooling for each connection will help. If is the case, how make it? How know wich connection get from the pool (because 2 threads can't share the connection)? I wonder if somebody already use sqlite in multu-threading with NSOperation or similar stuff, my searching only return "yeah, its possible" but let the details to my imagination...

  • Change UIImagePicker Navigation Bar style to blue

    - by vodkhang
    All of my view has a blue navigation bar but when I want user to choose a photo, the UIImagePicker is black. I tried to set the navigation bar of UIImagePickerController to blue using UIBarStyleDefault but it does not work for me, the color is still black. I tried with other UIBarStyle like UIBarStyleBlack and UIBarStyleOpaque as well but it doesn't change the navigation bar of the picker anyway. Here is my code // Let the user choose a new photo. UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.navigationBar.barStyle = UIBarStyleDefault; [self presentModalViewController:imagePicker animated:YES]; [imagePicker release];

  • XQuery - problem with recursive function

    - by H4mm3rHead
    Hi all, Im new on this project and am going to write, what i thought was a simple thing. A recursive function that writes nested xml elements in x levels (denoted by a variable). So far I have come up with this, but keeps getting a compile error. Please note that i have to generate new xml , not query existing xml: xquery version "1.0"; declare function local:PrintTest($amount) { <test> { let $counter := 0 if ($counter <= $amount ) then local:PrintTest($counter) else return $counter := $counter +1 } </test> }; local:PrintPerson(3) My error is: File Untitled1.xquery: XQuery transformation failed XQuery Execution Error! Unexpected token - " ($counter <= $amount ) t" I never understood xquery, and cant quite see why this is not working (is it just me or are there amazingly few resources on the Internet concerning XQuery?)

  • Why C# calls different overloaded method for different values of same type?

    - by Fabio Veronez
    Hello all, I have one doubt concerning c# method overloading call resolution. Let's suppose I have the following C# code: enum MyEnum { Value1, Value2 } public void test() { method(0); // this calls method(MyEnum) method(1); // this calls method(object) } public void method(object o) { } public void method(MyEnum e) { } Note that I know how to make it work but I would like to know why for one value of int (0) it calls one method and for another (1) it calls another. It sounds awkward since both values have the same type (int) but they are "linked" for different methods. Ps.: This is my first question here, i'm sorry if I made something wrong. =P

  • Is there Any Limit on stack memory!

    - by Vikas
    I was going through one of the threads. A program crashed because It had declared an array of 10^6 locally inside a function. Reason being given was memory allocation failure on stack leads to crash. when same array was declared globally, it worked well.(memory on heap saved it). Now for the moment ,Let us suppose, stack grows downward and heap upwards. We have: ---STACK--- ---HEAP---- Now , I believe that if there is failure in allocation on stack, it must fail on heap too. So my question is :Is there any limit on stack size? (crossing the limit caused the program to crash). Or Am I missing something?

  • Quick backup system for large projects

    - by kamziro
    I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big. Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored. What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)? Or is there any ingenious methods out there that people use?

  • How to properly use Gearman with my PHP application?

    - by luckytaxi
    For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?

  • How can something like BOSH be implemented using Java Servlets

    - by John
    BOSH (Bidirectional-streams Over Synchronous HTTP) is a sneaky way of implementing 2-way client-server communication in situations where true server-push is not allowed, most obviously to let a server push data to a browser client without having to use client polling. It works by the client sending a request to the server, and the server doesn't respond immediately... rather it remembers the request but only responds when it has some data to send. When this happens the client immediately sends another request so there is virtually always a 'stored request' sitting on the server ready to push data to the client. At least, that's how I think it works! My question is how you can do this using a Java EE stack i.e standard servlets. I'm rusty with them, is it allowed to send no response and cache the request somehow? If anyone could share (pseudo) code what a servlet class for handling BOSH might look like, I'd be real grateful.

  • What can I use for voluntary donations? (like Tipjoy)

    - by Ken
    There used to be a site called Tipjoy that would let me put a small "donate" button on a webpage, and users could donate small amounts (like 25c) to me easily. I think it was a pretty neat idea, since I want to have a way for people to give me money, and I don't like advertisements, and I don't update regularly enough to sell subscriptions like bloggers. I just have some simple web services and open-source program and I want an easy way for people to drop me some change if they think they're useful. I've found out that Amazon used to have a similar service, but it's also been shut down. Is there any similar web service available today? If not, what's the closest thing to offer -- a Paypal link?
