  • Choosing a method for a webservice

    - by Wrikken
    I'm asked to set up a new webservice which should be easily usable in whatever language (php, .NET, Java, etc.) possible. Of course rolling my own can be done, accepting different content-types (xml / x-www-form-urlencoded (normal post) / json / etc.), but an existing method or mechanism would of course be prefered, cutting down time spent on development for the consumers of the service. The webservice does accept modifications / sets (it is not only simply data retrieval), but those will most likely be quite a lot less then gets (we estimate about 2.5% sets, 97.5 gets). The term webservice here indicates the protocol should go over HTTP, not being able to implement it totally client sided (javascript in the end-users browser etc.), as it needs specific user authentication. Both gets and sets are pretty light on the parameter count (usually 1 to 4). Methods like REST (which I'd prefer for only gets), XML-RPC & SOAP (might be a bit overkill, but has the advantage of explicitly defined methods and returns) are the usual suspects. What in your opinion / experience is the most widely 'spoken' and most easily implementable protocol in different languages (seen from the consumers' viewpoint) which could fullfill this need?

  • Vehicle License Plate Detection

    - by Ash
    Hey all Basically for my final project at university, I'm developing a vehicle license plate detection application. Now I consider myself an intermediate programmer, however my mathematics knowledge lacks anything above secondary school, therefore producing detection formulae is basically impossible. I've spend a good amount of time looking up academic papers such as: http://www.scribd.com/doc/266575/Detecting-Vehicle-License-Plates-in-Images http://www.cic.unb.br/~mylene/PI_2010_2/ICIP10/pdfs/0003945.pdf http://www.eurasip.org/Proceedings/Eusipco/Eusipco2007/Papers/d3l-b05.pdf When it comes to the maths, I'm lost. Due to this testing various graphic images proved productive, for example: to However this approach is only catered to that particular image, and if the techniques were applied to different images, I'm sure a different, most likely poorer conversion would occur. I've read about a formula called the bottom hat morphology transform, which according to the first does the following: "Basically, the trans- formation keeps all the dark details of the picture, and eliminates everything else (including bigger dark regions and light regions)." Sadly I can't find much information on this, however the image within the documentation near the end of the report shows it's effectiveness. I'm aware this is complicated and vast, I'd just appreciate a little advice, even in terms of what transformation techniques I should focus on developing, or algorithm regarding edge detection or pixel detection. Few things I need to add Developing in C Sharp Confining the project to UK registration plates only I can basically choose the images to convert as a demonstration Thanks

  • Rails rake test returns an error message

  • CGContextDrawImage returning bad access

    - by Marcelo
    Hello guys, I've been trying to blend two UIImage for about 2 days now and I've been getting some BAD_ACCESS errors. First of all, I have two images that have the same orientation, basically I'm using the CoreGraphics to do the blending. One curious detail, everytime I modify the code, the first time I compile and run it on device, I get to do everything I want without any sort of trouble. Once I restart the application, I get error and the program shuts down. Can anyone give me a light? I tried accessing the baseImage sizes dynamically, but it gives me bad access too. Here's a snippet of how I'm doing the blending. UIGraphicsBeginImageContext(CGSizeMake(320, 480)); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, 0, 480); CGContextScaleCTM(context, 1.0, -1.0); CGContextDrawImage(context, rect, [baseImage CGImage]); CGContextSetBlendMode(context, kCGBlendModeOverlay); CGContextDrawImage(context, rect, [tmpImage CGImage]); [transformationView setImage:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext();

  • Class initialization and synchronized class method

    - by nybon
    Hi there, In my application, there is a class like below: public class Client { public synchronized static print() { System.out.println("hello"); } static { doSomething(); // which will take some time to complete } } This class will be used in a multi thread environment, many threads may call the Client.print() method simultaneously. I wonder if there is any chance that thread-1 triggers the class initialization, and before the class initialization complete, thread-2 enters into print method and print out the "hello" string? I see this behavior in a production system (64 bit JVM + Windows 2008R2), however, I cannot reproduce this behavior with a simple program in any environments. In Java language spec, section 12.4.1 (http://java.sun.com/docs/books/jls/second_edition/html/execution.doc.html), it says: A class or interface type T will be initialized immediately before the first occurrence of any one of the following: T is a class and an instance of T is created. T is a class and a static method declared by T is invoked. A static field declared by T is assigned. A static field declared by T is used and the reference to the field is not a compile-time constant (§15.28). References to compile-time constants must be resolved at compile time to a copy of the compile-time constant value, so uses of such a field never cause initialization. According to this paragraph, the class initialization will take place before the invocation of the static method, however, it is not clear if the class initialization need to be completed before the invocation of the static method. JVM should mandate the completion of class initialization before entering its static method according to my intuition, and some of my experiment supports my guess. However, I did see the opposite behavior in another environment. Can someone shed me some light on this? Any help is appreciated, thanks.

  • Call ASP.NET 2.0 Server side code from Javascript

    - by Kannabiran
    I'm struggling with this for the past 3 days. I need to call asp.net serverside code from Javascript when the user closes the browser. I'm using the following code to accomplish this. In my asp.net form I have various validation controls. Even if there are some validation errors, When I close the form the server side code works perfectly in my development box(windows 7). But the same code doesnt work in my production environment(windows server). Does it have something to do with the Validation summary or Validation controls. The button control has Causes validation set to false. So even if there is a validation error still my form will post back. Am I correct? I suspect the form is not getting post back to the server when there is a validation error. But i'm disabling all the validation controls in the javascript before calling the button click event. Can someone throw some light on this issue. There are few blogs which suggests to use JQUERY, AJAX (Pagemethods and script manager). function ConfirmClose(e) { var evtobj = window.event ? event : e; if (evtobj == e) { //firefox if (!evtobj.clientY) { evtobj.returnValue = message; } } else { //IE if (evtobj.clientY < 0) { DisablePageValidators(); document.getElementById('<%# buttonBrowserCloseClick.ClientID %>').click(); } } } function DisablePageValidators() { if ((typeof (Page_Validators) != "undefined") && (Page_Validators != null)) { var i; for (i = 0; i < Page_Validators.length; i++) { ValidatorEnable(Page_Validators[i], false); } } } //HTML <div style="display:none" > <asp:Button ID="buttonBrowserCloseClick" runat="server" onclick="buttonBrowserCloseClick_Click" Text="Button" Width="141px" CausesValidation="False" /> //Server Code protected void buttonBrowserCloseClick_Click(object sender, EventArgs e) { //Some C# code goes here }

  • Are all of the default scripts loaded by Magento really needed?

    - by pxl
    Here's a listing of all the scripts loaded by Magento by default: ../js/prototype/prototype.js //prototype library ../js/prototype/validation.js //don't know what this does ../js/scriptaculous/builder.js //don't know what this does ../js/scriptaculous/effects.js //base scriptaculous effects library? ../js/scriptaculous/dragdrop.js //component of scriptaculous effects ../js/scriptaculous/controls.js //not sure? ../js/scriptaculous/slider.js //more scriptaculous effects ../js/varien/js.js //don't know what this is ../js/varien/form.js //form validation scripts? ../js/varien/menu.js //menu/drop down menu scripts ../js/mage/translate.js //don't know what this does ../js/mage/cookies.js //don't know what this does these scripts total 316.8K of javascript... all in various states of being minified (for example, prototype.js isn't minified). So my first question: 1) Aside from prototype.js, are all of the others really that needed? and 2) What is the "correct" way to remove these scripts? Layout updates? Or hardcoded in templates? I want to make the loading of my magento site as light weight as possible. thanks!

  • Does fast typing influence fast programming? [closed]

    - by Lukasz Lew
    Many young programmers think that their bottleneck is typing speed. After some experience one realizes that it is not the case, you have to think much more than type. At some point my room-mate forced me to turn of the light (he sleeps during the night). I had to learn to touch type and I experienced an actual improvement in programming skill. The most surprising was that the improvement not due to sheer typing speed, but to a change in mindset. I'm less afraid now to try new things and refactor them later if they work well. It's like having a new tool in the bag. Have anyone of you had similar experience? Now I trained a touch typing a little with KTouch. I find auto-generate lessons the best. I can use this program to create new lessons out of text files but it's only verbatim training, not auto-generated based on a language model. Do you know any touch typing program that allows creation of custom, but randomized lessons?

  • P/Invoke declarations should not be safe-critical

    - by Bobrovsky
    My code imports following native methods: DeleteObject, GetFontData and SelectObject from gdi32.dll GetDC and ReleaseDC from user32.dll I want to run the code in full trust and medium trust environments (I am fine with exceptions being thrown when these imported methods are indirectly used in medium trust environments). When I run Code Analysis on the code I get warnings like: CA5122 P/Invoke declarations should not be safe-critical. P/Invoke method 'GdiFont.DeleteObject(IntPtr)' is marked safe-critical. Since P/Invokes may only be called by critical code, this declaration should either be marked as security critical, or have its annotation removed entirely to avoid being misleading. Could someone explain me (in layman terms) what does this warning really mean? I tried putting these imports in static SafeNativeMethods class as internal static methods but this doesn't make the warnings go away. I didn't try to put them in NativeMethods because after reading this article I am unsure that it's the right way to go because I don't want my code to be completely unusable in medium trust environments (I think this will be the consequence of moving imports to NativeMethods). Honestly, I am pretty much confused about the real meaning of the warning and consequences of different options to suppressing it. Could someone shed some light on all this? EDIT: My code target .NET 2.0 framework. Assembly is marked with [assembly: AllowPartiallyTrustedCallers] Methods are declared like this: [DllImport("gdi32")] internal static extern int DeleteObject(HANDLE hObject);

  • sqlite3 'database is locked' won't go away with retries

    - by Azarias
    I have a sqlite3 database that is accessed by a few threads (3-4). I am aware of the general limitations of sqlite3 with regards to concurrency as stated http://www.sqlite.org/faq.html#q6 , but I am convinced that is not the problem. All of the threads both read and write from this database. Whenever I do a write, I have the following construct: try: Cursor.execute(q, params) Connection.commit() except sqlite3.IntegrityError: Notify except sqlite3.OperationalError: print sys.exc_info() print("DATABASE LOCKED; sleeping for 3 seconds and trying again") time.sleep(3) Retry On some runs, I won't even hit this block, but when I do, it never comes out of it (keeps retrying, but I keep getting the 'database is locked' error from exc_info. If I understand the reader/writer lock usage correctly, some amount of waiting should help with the contention. What this sounds like is deadlock, but I do not use any transactions in my code, and every SELECT or INSERT is simply a one off. Some threads, however, keep the same connection when they do their operation (which includes a mix of SELECTS and INSERTS and other modifiers). I would appericiate it if you could shade a light on this, and also ways around fixing it (besides using a different database engine.)

  • Javascript array of dates - not iterating properly (jquery ui datepicker)

    - by PaulB
    Hi I have some code which builds an array of date ranges. I then call a function, passing it a date, and compare that date with dates in the array. I'm doing it this way because the dates are stored in a cms, and I'm manipulating the JqueryUI datepicker. Unfortunately my code only checks the first date range in the array - and I can't figure out why! I think it's probably something simple (/stupid!) - if anyone can shed some light on it I'd be extremely grateful! The code is below - the june-september range works fine, the december to jan is totally ignored... <script type="text/javascript" language="javascript"> var ps1 = new Date(2010, 06-1, 18); var pe1 = new Date(2010, 09-1, 03); var ps2 = new Date(2010, 12-1, 20); var pe2 = new Date(2011, 01-1, 02); var peakStart = new Array(ps1,ps2); var peakEnd = new Array(pe1,pe2); function checkDay(date) { var day = date.getDay(); for (var i=0; i<peakStart.length; i++) { if ((date > peakStart[i]) && (date < peakEnd[i])) { return [(day == 5), '']; } else { return [(day == 1 || day == 5), '']; } } } </script>

  • Displaying Flex Object References

    - by Pie21
    I have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view. However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes? Cheers.

  • Cannot send HTML Emails

    - by Zen Savona
    Well I'm trying to send a HTML email using gmail smtp from CI, and it seems to reject my emails when they have any amount of tables. No error is given, they just do not appear in my inbox.

  • What makes good web form styling for business applications?

    - by ProfK
    Styling forms (form elements) is something that even Eric Meyer prefers to avoid. However, most business forms, and that is where styling is at issue; 'contact us' forms are easy to style, put window estate at a premium, with more 'document level' (e.g. invoice) fields, plus 'detail level' (e.g. invoice line) fields. Factors I often find at play are: At my minimum, at least two horizontally adjacent fieldsets are required. In applications vs. public web pages, fixed positioning vs fluid layout is often better. Quantity of content is important, vs. exaggerated readability. Users know the system, and cues etc. take a back seat. In light of factors like these, is there any available guidence for styling web form based applications? Are there any CSS or JavaScript frameworks that would make my quest to style these applications better than Visual Studios still pathetic 'Auto-format' (what drugs were those people on? I will never take them.)

  • Basic Team Foundation Server 2010 Question - System Resource Usage?

    - by user127954
    Guys / Gals i have a real basic Team Foundation Server 2010 question. For those of you who have played around with tfs 2010 is it a lot more light weight than tfs2008 is? I remember installing all the pieces needed for TFS 2008 one one machine at work. I remember it being a pain to install (i know 2010 is supposed to be much better) We wanted to play around with it a little bit to see if it met our needs. Well it brought that machine to a screeching halt. I'm needing a source control repository for home and i thought why not just install tfs 2010 so i can get familiar with it and maybe in the future i can make a better sell to my organization and FINALLY get them to move off of Source Safe but my concern is i only have one server at home (granted i already have SQL Server installed) and don't want to buy a machine just for this purpose. I'd also like to get more familiar with CI too. Anyways, if team is going to be to heavy i'll just use subversion but i'd like to use TFS if possible. Any help would be appreciated. thanks, Ncage

  • How are developers using source control, I am trying to find the most efficient way to do source con

    - by RJ
    I work in a group of 4 .Net developers. We rarely work on the same project at the same time but it does happen from time to time.We use TFS for source control. My most recent example is a project I just placed into production last night that included 2 WCF services and a web application front end. I worked out of a branch called "prod" because the application is brand new and has never seen the light of day. Now that the project is live, I need to branch off the prod branch for features, bugs, etc... So what is the best way to do this? Do I simple create a new branch and sort of archive the old branch and never use it again? Do I branch off and then merge my branch changes back into the prod branch when I want to deploy to production? And what about the file and assembly version. They are currently at 1.0.0.0. When do they change and why? If I fix a small bug, which number changes if any? If I add a feature, which number changes if any? What I am looking for is what you have found to be the best way to efficiently manage source control. Most places I have worked always seem to bang heads with the source control system in on way or another and I would just like to find out what you have found that works the best.

  • C Programming: malloc() inside another function

    - by vikramtheone
    Hi Guys, I need help with malloc() inside another function. I'm passing a pointer and size to the function from my main() and I would like to allocate memory for that pointer dynamically using malloc() from inside that called function, but what I see is that.... the memory which is getting allocated is for the pointer declared withing my called function and not for the pointer which is inside the main(). How should I pass a pointer to a function and allocate memory for the passed pointer from inside the called function? Can anyone throw light on this? Help!!! Vikram I have written the following code and I get the output as shown below SOURCE: main() { unsigned char *input_image; unsigned int bmp_image_size = 262144; if(alloc_pixels(input_image, bmp_image_size)==NULL) printf("\nPoint2: Memory allocated: %d bytes",_msize(input_image)); else printf("\nPoint3: Memory not allocated"); } signed char alloc_pixels(unsigned char *ptr, unsigned int size) { signed char status = NO_ERROR; ptr = NULL; ptr = (unsigned char*)malloc(size); if(ptr== NULL) { status = ERROR; free(ptr); printf("\nERROR: Memory allocation did not complete successfully!"); } printf("\nPoint1: Memory allocated: %d bytes",_msize(ptr)); return status; } PROGRAM OUTPUT: Point1: Memory allocated ptr: 262144 bytes Point2: Memory allocated input_image: 0 bytes

  • What Color is the Windows' System.Control? (Visual Studio Design View)

    - by jp2code
    In Visual Studio Design View, the selection of Form Colors in the Properties Pane are selectable from the "Custom", "Web", and "System" tabs. Of course, the color number can be used, too. When the "System" Tab is selected, the colors in the list depend on what type of Theme the Computer User has set on the PC. I'd like to stick with this, but I need to know how to "read in" the colors. I have controls that I create "on-the-fly" or often need to change a color back after getting the person's attention using a blink/flicker technique. How do I get the list of System Theme colors? Most forms have a BackColor that defaults to "Control", which looks like a very light gray under Windows 7, running the default Windows 7 Theme. I've managed to grab a color by physically reading the ARGB value in code, but I'd rather have a way to access the colors by their Theme Name, if that can be done. public Form1() { Color cControl = this.BackColor; Console.WriteLine(cControl.Name); // there is not always a name! } Does anyone know what I'm talking about?

  • Class library reference problem

    - by Anindya Chatterjee
    I am building a class library and using its default namespace as "System". There suppose I am creating a generic data structure say PriorityQueue and putting it under System.Collections.Generic namespace. Now when I am referencing that library from another project, I can't see PriorityQueue under "System.Collections.Generic" namespace anymore. Though the library is referenced in that project I can not access any of the classes in it. My question was mscorlib and System.dll share similar namespaces, but still classes from both the assembly is accessible, but why can't mine? If I put a public class under System.Collections.Generic namespace in my class library and refer that library in a project and use a statement like "using System.Collections.Generic", still why I can't access my class there? This was an experimentation I did, I know using System namespace is not encouraged in custom class library, but I want to know the reason behind why I can't access my class in this special case? Please someone shed some light on it. PS: Last time I asked similar question but put it wrongly, so people got misunderstood and I didn't get my answer. This time I am trying to put it correctly as far as I can. Sorry for the misunderstanding.

  • Trouble with building up a string in Clojure

    - by Aki Iskandar
    Hi gang - [this may seem like my problem is with Compojure, but it isn't - it's with Clojure] I've been pulling my hair out on this seemingly simple issue - but am getting nowhere. I am playing with Compojure (a light web framework for Clojure) and I would just like to generate a web page showing showing my list of todos that are in a PostgreSQL database. The code snippets are below (left out the database connection, query, etc - but that part isn't needed because specific issue is that the resulting HTML shows nothing between the <body> and </body> tags). As a test, I tried hard-coding the string in the call to main-layout, like this: (html (main-layout "Aki's Todos" "Haircut<br>Study Clojure<br>Answer a question on Stackoverfolw")) - and it works fine. So the real issue is that I do not believe I know how to build up a string in Clojure. Not the idiomatic way, and not by calling out to Java's StringBuilder either - as I have attempted to do in the code below. A virtual beer, and a big upvote to whoever can solve it! Many thanks! ============================================================= ;The master template (a very simple POC for now, but can expand on it later) (defn main-layout "This is one of the html layouts for the pages assets - just like a master page" [title body] (html [:html [:head [:title title] (include-js "todos.js") (include-css "todos.css")] [:body body]])) (defn show-all-todos "This function will generate the todos HTML table and call the layout function" [] (let [rs (select-all-todos) sbHTML (new StringBuilder)] (for [rec rs] (.append sbHTML (str rec "<br><br>"))) (html (main-layout "Aki's Todos" (.toString sbHTML))))) ============================================================= Again, the result is a web page but with nothing between the body tags. If I replace the code in the for loop with println statements, and direct the code to the repl - forgetting about the web page stuff (ie. the call to main-layout), the resultset gets printed - BUT - the issue is with building up the string. Thanks again. ~Aki

  • Changing middle mouse behavior in Adobe AIR HTML Control?

    - by Qz
    I'm using the Flex 4/Adobe AIR mx:HTML control in a project and I'm trying to figure out how to change the middle mouse behavior. For some reason the control treats middle mouse clicks and drags exactly the same as left mouse clicks and drags, navigating through links and selecting text -- everything. For my project I need to use the middle mouse button for a different function. I've figured out how to hook into the events (although mouseUp and mouseDown for Left/Middle don't work over HTML whitespace, perhaps because of the default behavior). However I can't figure out how to stop the default behavior for middle mouse events. Calling preventDefault() on the HTML control mouse events doesn't work, presumably because the behavior is handled by the HTMLLoader within the HTML control, which I imagine hooks mouse events to the actual HTML content displayed on screen. Unfortunately I can't view the source for HTMLLoader to figure out what's going on, and browsing the properties and events doesn't shed any light on the situation either. Any help would be greatly appreciated! Oh, if anyone can suggest a different embeddable HTML renderer that doesn't have this problem, then that might work too, I'm not too tied to WebKit (although I do need to use AIR)

  • Why is Func<T> ambiguous with Func<IEnumerable<T>>?

    - by Matt Hamilton
    This one's got me flummoxed, so I thought I'd ask here in the hope that a C# guru can explain it to me. Why does this code generate an error? class Program { static void Main(string[] args) { Foo(X); // the error is on this line } static String X() { return "Test"; } static void Foo(Func<IEnumerable<String>> x) { } static void Foo(Func<String> x) { } } The error in question: Error 1 The call is ambiguous between the following methods or properties: 'ConsoleApplication1.Program.Foo(System.Func<System.Collections.Generic.IEnumerable<string>>)' and 'ConsoleApplication1.Program.Foo(System.Func<string>)' C:\Users\mabster\AppData\Local\Temporary Projects\ConsoleApplication1\Program.cs 12 13 ConsoleApplication1 It doesn't matter what type I use - if you replace the "String" declarations with "int" in that code you'll get the same sort of error. It's like the compiler can't tell the difference between Func<T> and Func<IEnumerable<T>>. Can someone shed some light on this?

  • IntelliJ Doesn't Notice Changes in Interface

    - by yar
    [I've decided to give IntelliJ another go (to replace Eclipse), since its Groovy support is supposed to be the best. But back to Java...] I have an Interface that defines a constant public static final int CHANNEL_IN = 1; and about 20 classes in my Module that implement that interface. I've decided that this constant was a bad idea so I did what I do in Eclipse: I deleted the entire line. This should cause the Project tree to light up like a Christmas tree and all classes that implement that interface and use that constant to break. Instead, this is not happening. If I don't actually double-click on the relevant classes -- which I find using grep -- the module even builds correctly (using Build - Make Module). If I double-click on a relevant class, the error is shown both in the Project Tree and in the Editor. I am not able to replicate this behavior in small tests, but in large modules it works (incorrectly) this way. Is there some relevant setting in IntelliJ for this?
