  • Free cross-platform library to convert numbers (money amounts) to words?

    - by bialix
    I'm looking for cross-platform library which I can use in my C application to convert money amounts (e.g. $123.50) to words (one hundred twenty three dollars and fifty cents). I need support for multiple currencies: dollars, euros, UK pounds etc. Although I understand this is not hard at all to write my own implementation, but I'd like to avoid reinventing wheel. I've tried to google it, but there is too much noise related to MS Word converters. Can anybody suggest something? UPDATE numerous comments suggest to write my own implementation because it's really easy task. And I agree. My point was about support of multiple currencies in the same time and different business rules to spell the amounts (should be fractional part written as text or numbers? etc.) As I understand serious business applications have such library inside, but I think there is nothing open-source available, maybe because it seems as very easy task. I'm going to write my own libary and then open-source it. Thanks to all.

  • PHP OOP: Unique method per argument type?

    - by sunwukung
    I'm writing a little homebrew ORM (academic interest). I'm trying to adhere to the TDD concept as a training exercise, and as part of that exercise I'm writing documentation for the API as I develop the class. Case in point - I'm working on a classic "getCollection" type mapper class. I want it to be able to retrieve collections of asset X (let's say blog posts) for a specific user, and also collections based on an arbitrary array of numeric values. So - you might have a method like any one of these $User = $UserMapper->load(1); $ArticleCollection = $ArticleMapper->getCollection(range(10,20)); $ArticleCollection = $ArticleMapper->getCollection($User); $ArticleCollection = $ArticleMapper->getCollection($User->getId()); So, in writing the documentation for the getCollection method - I want to declare the @param variable in the Docblock. Is it better to have a unique method for each argument type, or is it acceptable to have a method that delegates to the correct internal method/class based on argument type?

  • Fastest reliable way for Clojure (Java) and Ruby apps to communicate

    - by jkndrkn
    Hi There, We have cloud-hosted (RackSpace cloud) Ruby and Java apps that will interact as follows: Ruby app sends a request to Java app. Request consists of map structure containing strings, integers, other maps, and lists (analogous to JSON). Java app analyzes data and sends reply to Ruby App. We are interested in evaluating both messaging formats (JSON, Buffer Protocols, Thrift, etc.) as well as message transmission channels/techniques (sockets, message queues, RPC, REST, SOAP, etc.) Our criteria: Short round-trip time. Low round-trip-time standard deviation. (We understand that garbage collection pauses and network usage spikes can affect this value). High availability. Scalability (we may want to have multiple instances of Ruby and Java app exchanging point-to-point messages in the future). Ease of debugging and profiling. Good documentation and community support. Bonus points for Clojure support. What combination of message format and transmission method would you recommend? Why? I've gathered here some materials we have already collected for review: Comparison of various java serialization options Comparison of Thrift and Protocol Buffers (old) Comparison of various data interchange formats Comparison of Thrift and Protocol Buffers Fallacies of Protocol Buffers RPC features Discussion of RPC in the context of AMQP (Message-Queueing) Comparison of RPC and message-passing in distributed systems (pdf) Criticism of RPC from perspective of message-passing fan Overview of Avro from Ruby programmer perspective

  • How to calculate the latlng of a point a certain distance away from another?

    - by Rene Saarsoo
    To draw a circle on map I have a center GLatLng (A) and a radius (r) in meters. Here's a diagram: ----------- --/ \-- -/ \- / \ / \ / r \ | *-------------* \ A / B \ / \ / -\ /- --\ /-- ----------- How to calculate the GLatLng at position B? Assuming that r is parallel to the equator. Getting the radius when A and B is given is trivial using the GLatLng.distanceFrom() method - but doing it the other way around not so. Seems that I need to do some heavier math.

  • How do you return draggable content to their original positions in iPhone dev?

    - by Matt Thomas
    I am wanting to create a button in my iPhone app that when touched will return other draggable elements to their original position. I have looked at the Apple "MoveMe' example, but that returns the button to the center of the screen. I want to be able to position draggable objects around the screen, drag the objects within the app, and then return them to their original starting positions by pressing a designated button. Any help appreciated!

  • How to input test data using the DecisionTree module in python?

    - by lifera1n
    On the Python DescisionTree module homepage (DecisionTree-1.6.1), they give a piece of example code. Here it is: dt = DecisionTree( training_datafile = "training.dat", debug1 = 1 ) dt.get_training_data() dt.show_training_data() root_node = dt.construct_decision_tree_classifier() root_node.display_decision_tree(" ") test_sample = ['exercising=>never', 'smoking=>heavy', 'fatIntake=>heavy', 'videoAddiction=>heavy'] classification = dt.classify(root_node, test_sample) print "Classification: ", classification My question is: How can I specify sample data (test_sample here) from variables? On the project homepage, it says: "You classify new data by first constructing a new data vector:" I have searched around but have been unable to find out what a data vector is or the answer to my question. Any help would be appreciated!

  • Programmatically setup a PEAP connection in Windows Mobile

    - by tomlog
    I have been working on this for a few days and this is doing my head in: Our application is built using the .NET Compact Framework 2.0 and running on Windows Mobile 5 & 6 devices. We can set the WLAN connection of the device programmatically using the Wireless Zero Config functions (described here: msdn.microsoft.com/en-us/library/ms894771.aspx), most notably the WZCSetInterface function which we pinvoke from our application. This works fine for WEP and WPA-PSK connections. In a recent effort to add support for WPA2 networks we decided to modify the code. We have successfully added support for WPA2 which uses a certificate for the 802.1x authentication by setting the correct registry settings before calling WZCSetInterface. Now we want to do the same for WPA2 using PEAP (MS-CHAPv2) authentication. When manually creating such a connection in Windows Mobile the user will be prompted to enter the domain/user/password details. In our application we will have those details stored locally and want to do this all programmatically without any user intervention. So I thought going along the same route as the certificate authentication, setting the correct registry entries before calling WZCSetInterface. The registry settings we set are: \HKCU\Comm\EAP\Config\[ssid name] Enable8021x = 1 (DWORD) LastAuthSuccessful = 1 (DWORD) EapTypeId = 25 (DWORD) Identity = "domain\username" (string) Password = binary blob containing the password that is encrypted using the CryptProtectData function (described here: msdn.microsoft.com/en-us/library/ms938309.aspx) But when these settings are set and I call WZCSetInterface with the correct parameters, it still prompts me with the User Logon dialog asking for the domain/username/password. Has anyone got an idea what I need to do to prevent the password dialog from appearing and connect straight away with the settings stored in the registry?

Any help will be greatly appreciated. Thanks, Subhen

  • ASP.Net MVC and Windows 7 404 error

    - by Paul Rivers
    O.K. Stupid question..... I sepnt nearly a day getting an MVC site working, and then I published it. After that, the hell began. I'm using Windows 7, Visual Studio 2008 and MVC. I published it and first the Default.aspx wouldn't come up. I gave up on playing with that for a few and just did the easy thing a typed in default.aspx. I'll fix that problem later. So, I clicked on one of my navigation buttons which prior to this worked just fine in the internal development IIS, and I get a 404 error. I spent two days surfing the Microsoft support forums and every other support forum I can find. No fix. So, I tried something a little different. Just to see if I screwed up. I created a new TestMVC application. Set the output to a website on the local IIS. Compiled and after typing in the default.aspx (it was set as the startup file in the project) I then clicked on the About button on the base MVC application. And what do I get? 404. I know this is new, folks, but this is crazy. What is it about this process that would take this much effort to get it right, especially since it works on the test server.

  • Function returning pointer to struct

    - by GammaGuy
    I am having some issues with code that is returning a pointer to a struct declared inside a class. Here is my code so far: SortedList.h #ifndef SORTEDLIST_H #define SORTEDLIST_H class SortedList{ public: SortedList(); ... private: struct Listnode { Student *student; Listnode *next; }; static Listnode *copyList (Listnode *L); }; #endif SortedList.cpp #include "SortedList.h" ... // Here is where the problem lies Listnode SortedList::*copyList(Listnode *L) { return 0; // for NULL } Apparently, the copy list method wont compile. I am using Microsoft Visual Studio and the compiler tells me that "Listnode" is unidentified.

  • Is there any possibility of rendering differences betweeen firefox 3 and 3.5 and IE 7 and 8, even if

    - by metal-gear-solid
    I'm making a site for European client and he said Firefox 3 and IE 7 and 8 has more user than others browser for desktop in Europe http://gs.statcounter.com/#browser_version-eu-monthly-200812-201001-bar I've only IE 7 and Firefox 3.5.7 installed in my PC. Should I download portable Firefox 3.0 and test in it too even if I'm not using any new css property/selector which only has support in Firefox 3.5 or testing in 3.5.7 would be enough? And for IE testing in IE 7 would be enough or should i check my site in IE8 (downloading VPC image of IE8 and testing in VM) even if I'm not using any new css property/selector which only has support in IE8? Or is it necessary to use <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in <head> ? But what will happen when user will switch compatibility mode to IE 8 default rendering mode? Can we make site compatible in IE 7 and 8 both without using <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />? If yes, then what special we need to do.care/consider in css to make site identical in both?

  • Microphone input

    - by George
    I'm trying to build a gadget that detects pistol shots using Android. It's a part of a training aid for pistol shooters that tells how the shots are distributed in time and I use a HTC Tattoo for testing. I use the MediaRecorder and its getMaxAmplitude method to get the highest amplitude during the last 1/100 s but it does not work as expected; speech gives me values from getMaxAmplitude in the range from 0 to about 25000 while the pistol shots (or shouting!) only reaches about 15000. With a sampling frequency of 8kHz there should be some samples with considerably high level. Anyone who knows how these things work? Are there filters that are applied before registering the max amplitude. If so, is it hardware or software? Thanks, /George

  • Use ImageMagick to place an image inside a larger canvas

    - by Mike
    Getting started with ImageMagic and trying to find a way to do this... If an image is less than 50 pixels tall or 50 pixels wide, I'd like to place it (un-scaled) in the horizontal/vertical center of a new 50x50 pixel canvas on top of a white background - and save that as the new image. Anyone know if this is possible with ImageMagick? Thanks!

  • Is there any way to access codeigniter language and config properties from included javascript files

    - by ubermensch
    Good morning! I'm having great success so far with CodeIgniter. I'm new to PHP and web development in general, but I feel that CodeIgniter is giving me a leg up while I catch up on the basics. My question for today is this - I have been happily loading config and lang values from my views for a while now, and everything is working fine. But what about JavaScript files being linked into my views? Is there any way to make the $this-lang-line and $this-config-item function references available to me in my JavaScript files? I am implementing jQuery client-side validation, and would like to pull in my error messages from the server, both to support internationalisation and to make sure that validation gracefully degrades if JavaScript is not available, in that the error messages pushed back into the view from the server-side validation are identical to those displayed dynamically by the jQuery validation. I would not like to have to keep coming back to make sure that these strings are kept in sync. As for internationalisation, I'm fresh out of ideas on how to support that if it turns out that lang and config item strings are completely unavailable from my JS files. Any help you can provide would be greatly appreciated! :)

  • How do i change Object to String in a class which extends AsyncTask?

    - by Filip V.
    I'm learning from Google's Android developing tutorial and i came across a problem. On this link https://developer.android.com/training/basics/network-ops/connecting.html#AsyncTask it says to create a class that extends AsyncTask. So when i write the class it automatically implements the method as follows: private Object doInBackground(Object... args) {..} //it's fine but when i try writing just as it says in the tutorial: private String doInBackground(String... args) {..} //it gives an error and the error says: The method doInBackground(String...) of type MainActivity.DownloadWebpageText must override a superclass method. So how do i change Object to String without getting an error there?

  • ForEach loop in Mathematica.

    - by dreeves
    I'd like something like this: ForEach[i_, {1,2,3}, Print[i] ] Or, more generally, to destructure arbitrary stuff in the list you're looping over, like: ForEach[{i_, j_}, {{1,10}, {2,20}, {3,30}}, Print[i*j] ] (Meta-question: is that a good way to call a ForEach loop, with the first argument a pattern like that?) ADDED: Some answerers have rightly pointed out that usually you want to use Map or other purely functional constructs and eschew a non-functional programming style where you use side effects. I agree! But here's an example where I think this ForEach construct is supremely useful: Say I have a list of options (rules) that pair symbols with expressions, like attrVals = {a -> 7, b -> 8, c -> 9} Now I want to make a hash table where I do the obvious mapping of those symbols to those numbers. I don't think there's a cleaner way to do that than ForEach[a_ -> v_, attrVals, h[a] = v] ADDED: I just realized that to do ForEach properly, it should support Break[] and Continue[]. I'm not sure how to implement that. Perhaps it will need to somehow be implemented in terms of For, While, or Do since those are the only loop constructs that support Break[] and Continue[]. If anyone interested in this wants to ask about that as a separate question, please do!

  • How to preserve the state of JavaScript closure?

    - by Uccio
    I am working on a migration platform to migrate web applications from a device to another. I am extending it to add the support for preserving JavaScript state. My main task is to create a file representing the current state of the executing application, to transmit it to another device and to reload the state in the destination device. The basic solution I adopted is to navigate the window object and to save all its descendant properties using JSON as base format for exportation and extending it to implement some features: preserving object reference, even if cyclic (dojox.json.ref library) support for timers Date non-numericproperties of arrays reference to DOM elements The most important task I need to solve now is exportation of closures. At this moment I didn't know how to implement this feature. I read about the internal EcmaScript property [[scope]] containing the scope chain of a function, a list-like object composed by all the nested activation context of the function. Unfortunately it is not accessible by JavaScript. Anyone know if there is a way to directly access the [[scope]] property? Or another way to preserve the state of a closure?
