  • Suggest encoding which removes slashes which I can use as the format for REST-style URL-paramteters

    - by Binary255
    Given a path to a REST style URL: http://site.com/rest/customer/foo/robot/bar/1 When you GET it, it returns a PDF to the foo-customer containing page 1 of the bar-URL. While foo is the name of the customer bar is an URL. The URL usually contains slashes and might look something like this: http://anothersite.com/interestingarticle.html As REST URL's separate arguments by slashes I can't just put it into the REST URL above. Which encoding should I use? I can't use Base 64 as it utilizes the slash as well. As a technical note I will encode the URL in a .NET-application and decode it in PHP.

  • How to play a set of jpeg files as a movie?

    - by RJ
    I have a set of jpeg images where eacg image has an associated description. e.g. im1.jpg - suspect enters bank im7.jpg - suspect hands teller a note imj41.jpg - teller gives suspect a bag ... ... It's trivial to view these images individually and see the description but how do I play this as a movie? I need to play the images and when I encounter one with a description, display the description in a status pane. Do I need to convert the images into a movie, if so how? How do I get the player to notify me when the description frame is encountered? I'm using Windows. language doesn't matter, I just need the concept right now.

  • What exactly is a memory page fault?

    - by dontWatchMyProfile
    From the docs: Note: Core Data avoids the term unfaulting because it is confusing. There's no “unfaulting” a virtual memory page fault. Page faults are triggered, caused, fired, or encountered. Of course, you can release memory back to the kernel in a variety of ways (using the functions vm_deallocate, munmap, or sbrk). Core Data describes this as “turning an object into a fault”. Is a Fault in Core Data essentially a memory page fault? I have only a slight idea about what a memory page is. I believe it's a kind of "piece of code in memory" which is needed to execute procedures and stuff like that, and as the app is runing, pieces of code are sucked into memory as "pages" and thrown away as they're not needed anymore. Probably 99% wrong ;) Anyone?

  • SQL: joining multiples tables into one.

    - by Graveen
    I have 4 tables. r1, r2, r3 and r4. The table columns are the following: rId | rName I want to have, in fine, an unique table - let's call it R. Obviously, R will have the following structure: rTableName | rId | rName I'm looking for a solution, and the more natural for me is to: add a single column to all rX insert this column the table name i'm processing generate SQLs and concatenate them all Although I see exactly how to perform 1 and 3 with batching, editing, etc... (I have only to perform it once and for all), I don't see how to do the point 2: self-getting the tablename to insert into SQL. Have you an idea / or a different way to do that could solve my problem? Note: In fact, there are 250+ rX tables. That's why i can't do this manually. Note2: Precisely, this is with MySQL.

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • Setting custom control properties

    - by Rob
    I though it would be very simple but I can not get it today. I have a user control, with a grid control contained in it. public Unit Width { get { return CustomerGrid.Width; } set { CustomerGrid.Width = value; } } I expose the width property and when I set it in the designer it works at run-time but not design time. What class do I inherit from or method to override to get my controls to function at design time. Note I tried to inherit from WebControl but got the message Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class

  • inserting datetimes into database using java

    - by gordatron
    Hi, I am wanting to insert a datetime into a MySql data base using Java and a prepared statement: Calendar cal = Calendar.getInstance(); PreparedStatement stmnt = db.PreparedStatement("INSERT INTO Run " + "(Time) VALUE (?) "); stmnt.setDate(1, new java.sql.Date(cal.getTime())); stmnt.executeQuery(); NOTE: thre is currently an error - cannot find symbol (java.sql.Date) line 4 here db is an instance of a sort of wrapper class that exposes what I need from java.sql - its just getting a prepared statement from my connection object here. Time (the column) is a date time in my database, and I can only see sedDate and setTime method but I want to store both - also my code does not work anyway ;-) if anyone could give me some pointers on inserting a combined date time (current time would be a great help as that's my first goal) into a MySql DB using a prepared statement I would be very grateful. Thanks

  • How good is the Rails sanitize() method?

    - by Horace Loeb
    Can I use ActionView::Helpers::SanitizeHelper#sanitize on user-entered text that I plan on showing to other users? E.g., will it properly handle all cases described on this site? Also, the documentation mentions: Please note that sanitizing user-provided text does not guarantee that the resulting markup is valid (conforming to a document type) or even well-formed. The output may still contain e.g. unescaped ’<’, ’’, ’&’ characters and confuse browsers. What's the best way to handle this? Pass the sanitized text through Hpricot before displaying?

  • MySQL Accept Any Password

    - by George
    Suppose that I have a test server with a large group of test accounts. The test accounts have unknown passwords which are hard-coded into the application's reports and are stored encrypted in the mysql.users table. Is there any option or hack which can be used to make mysql accept any text as the "correct" password for an account? For example: Update mysql.user Set Password="*" where 1=1 Note: The above line wouldn't work because it would literally set the password to "*" and not the wildcard character. However, I am looking for a way to create a mysql account which would accept anything as a valid password. This machine is disconnected from the network and I have full access to the mysql database...

  • problem with iOS 4.2 when user press the list view item to go to UIwebview page and the navigation button disappears on the second visit

    - by seahorse
    My app is a Navigation based application. The main menu contains the list view items. if I clicks one of them, it goes to next view which in this case take me to UIwebview embedded web site. Everything is looking great. I can view the content of web page, the navigation control back button which takes to the main menu if I press it. However, I'm having issue when I try to go back to main menu if i visit that subview the second time. It loads the content of UIwebview web page, but the navigation button is gone and won't let me go back to main menu. This problem only appears on latest iOS 4.2 version. Otherwise it works great on 3.1 to 4.1. I would appreciate any hints or inputs. Note this seems not working for subview using UIWebview embedded web content. I don't have any issue with other subviews

  • Reference variable to an object instantiated/initialized in another class in Java

    - by Alex
    The reason I'm asking is because I'm getting NullPointerException. I now this is very easy but I'm pretty new programming and find this a bit confusing. So say I have initialized an object in a class and want to access that same object from another class. Like now for instance I'm working on a small Chess game, in my model Game class I have an instance of Board, an object. Board, in turn, has an array of Squares. Square[][]. Game has board, board has Square[][]. Now if I want to access the Square[][] through the object board (in Game) of type Board. Do I just declare a variable with the same name and type or do I have to initialize it again? Board board OR Board board = new Board(); Note, I have already initialized board in the class Game so if I do it again, won't they be two totally different Board objects?

  • C++ inheritance question

    - by user233973
    Hi guys, I have a C++ inheritance related question. I have a set of classes like this (I have not given the complete class structure coz I am lazy :) ). I want to access chiComponent class public methods using com pointer. How should I go about it? Note that I am having to change the object which "com" is pointing to in a lot of places. So I do not think I can have another chiComponent *ccom = <some_cast> com; ccom.chiComponentMethod() How should I go about it? class Component{ }; class chiComponent : public Component { public: void chiComponentMethod() { cout << "Hi! Chi component function called!!"; } } class parent { protected: Component *com; }; class child : public parent{ public: child() { com = new chiComponent(); } } Regards Arun

  • Displaying only the similarities between 20 or so files?

    - by leeand00
    Say I've got a directory full of html pages. Their headers and footers are basically the same, but I want to be able to see only the portions of all the pages that are the same. I'd like to call it an n-way merge, but that isn't what it is, it's looking for just the similarities between the header and the footers of all the files. (and my header I don't mean just the <head> tag, but rather the portions of the page that are alike). Note: There are like 20 html files. Is there a name for a tool that does this?

  • Maximum compression of a MSI install using WIX

    - by MX4399
    I used to build installs for an app with NSIS and the final self extractor was 1.2 MB. Now I need to use WIX due to operational needs and the same install comes out at 4.2 MB. I set the compressed flags as the docs and specs indicated on the package node. Using 7z to zip the MSI results in a 2.4 MB zip file. Question: How can I do a maximum compress on the MSI or create a small MSI (e.g. remove unneeded resources etc) ? Note - size is uber important and I have to use MSI/WIX now - this is a show stopper!

  • Re-use aliased field in SQL SELECT STATEMENT

    - by Bad Display Name
    Hi, the question is hard to define without giving an example, e.g. I'd like to achieve something like this : SELECT (CASE WHEN ...) AS FieldA, 20 + FieldA AS FieldB FROM Tbl Assuming that by "..." I've replaced a long and complex CASE statement, hence I don't want to repeat it when selecting FieldB and use the aliased FieldA instead. IS THIS EVEN POSSIBLE? What could be a workaround? Note, that this will return multiple rows , hence the DECLARE/SET outside the SELECT statement is no good in my case. PLEASE HELP. P.S. I am using SQL 2008

  • An RMIPRoxyFactoryBean factory in Spring?

    - by Robert Munteanu
    I'm currently using a Spring RmiProxyFactoryBean to access remote services. Since requirements have changed, I need to specify at runtime a different host - there can be many of them - , but the remoteServiceInterface and the non-host components of the remoteServiceUrl remain the same. Conceptually speaking, I'd see a bean definition similar to: <bean class="org.springframework.remoting.rmi.RmiProxyFactoryBeanFactory"> <property name="serviceInterface" value="xxx"/> <property name="serviceUrl" value="rmi://#{HOST}:1099/ServiceUrl"/> </bean> which exposes a Object getServiceFor(String hostName); Is there such a service available with Spring? Alternatively, do you see another way of doing this? Please note that the host list will not be known at compile or startup time, so I can't generate it in the xml file.

  • How to do REST with PUT and DELETE

    - by Svish
    It says about the type option of the jQuery.ajax() method that The type of request to make ("POST" or "GET"), default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers. So... Does that mean that PUT and DELETE won't work if the browser does not support it, or just that PUT and DELETE can not be done natively by the user in the browser? If I can't or shouldn't use those, what do people usually do instead? Send the method as a a GET or POST parameter instead? Or?

  • android localization: Is it a good practice to have only needed resource to put in localized folder?

    - by MobileDev123
    Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

  • When did people first start thinking 'C is portable assembler' ?

    - by Jacques Carette
    It seems to be an 'accepted concept' in the popular culture of programming languages that 'C is portable assembler'. I have first heard this at least 15 years ago. But when did it really become part of the popular culture? Note: if you don't agree that 'C is portable assembler', please just skip this question. This question is about 'popular culture of programming'. I'll add a comment to this question which you can up-vote for those who disagree with that statement.

    I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

  • Simple Search and Replace use of Regular Expression

    - by nunos
    So, I am adapting some code I found online to suit my needs. However, my set_pixel function has two more parameters. Since there are lots of calls to this function even doing a quick paste over would be very tedious. So, I thought this would be a good time for me to learn some simple regular expressions. So, I have calls of this type: set_pixel(arg1, arg2); which I want to change to something like: set_pixel(arg1, arg2, arg3, arg4); Note: arg1 and and 2 should be preserved, whereas arg3 and arg4 are most of the time the same. How can I achieve this?

  • Show parts of the result of an SQL statement using PHP

    - by mouthpiec
    I have an SQL query which returns a set of data (around 40-50 tuples). I would like to display the results 5 at a time on an HTML page using PHP. I already managed to have the right SELECT statement, but i am having problems to display the results 5 by 5 using a "more" button. Can you please help? Note that every time i call the query, the data is being randomized, so it is not possible to set limits and call the query again. I have to find the method to store the results somewhere, and then show them 5 by 5.
