  • How to read special characters from stdin in Python?

    - by erickrf
    I'm having trouble reading special characters from stdin. Here are my attempts: import os dir = raw_input("Dir name: ") Dir name: c:/á os.chdir(dir) WindowsError: [Error 2] The system cannot find the file specified: 'c:/\x81\xe1' Ok, so I tried to get the default system encoding and recode the string from stdin: import locale encoding = locale.getdefaultlocale()[1] print encoding cp1252 unicode(dir, encoding) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Python26\lib\encodings\cp1252.py", line 15, in decode return codecs.charmap_decode(input,errors,decoding_table) UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 3: character maps to <undefined> Now, I don't know how to solve this. Nor can I understand - why is there a problem when I try to access a directory with a name written in the system default encoding itself??

  • Add mask to input

    - by Lodewijk Wensveen
    I'm trying to achieve the seemingly impossible task of adding an mask to a input field. I have the following code: function addActivationCode(){ newRow = jQuery("div.activationcode:last-child").clone(); newRow.insertAfter(jQuery("div.activationcode:last-child")); newRow.attr("id", "coderow-" + Math.round(Math.random() * 10000)); newRow.find("input").val(""); find("input").mask("9999-9999-9999-9999"); newRow.find("a.coderemove").attr("onclick", "removeActivationCode('" + newRow.attr("id") + "'); return false;"); } function removeActivationCode(id){ jQuery("div#" + id).remove(); } Now I to get the .mask working on my input fields, so far I've only got it working on the new row I'm making and not on the original one. Can anyone help me out?

  • ByteStrings in Haskell

    - by Jon
    So i am trying to write a program that can read in a java class file as bytecode. For this i am using Data.Binary and Data.ByteStream. The problem i am having is because im pretty new to Haskell i am having trouble actually using these tools. module Main where import Data.Binary.Get import Data.Word import qualified Data.ByteString.Lazy as S getBinary :: Get Word8 getBinary = do a <- getWord8 return (a) main :: IO () main = do contents <- S.getContents print (getBinary contents) This is what i have come up with so far and i fear that its not really even on the right track. Although i know this question is very general i would appreciate some help with what i should be doing with the reading.

  • Changing an extention method from linq-to-sql to entity framework

    - by Jova
    I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

  • Webreference vs servicereference. Why ony one works ?

    - by phenevo
    Hi, I've got two applications. One uses webreference to my webservice, and second use servicereference to my webservice. There is metohod which I'm invoking: [WebMethod] public Car[] GetCars(string carCode) { Cars[] cars= ModelToContract.ToCars(MyFacade.GetCars(carCode); return cars; } Car has two pools: string Code {get;set;} CarType Type {get;set;} public enum CarType { Van=0, Pickup=1 } I'm debuging this webMethod, and... at the end webservice throw good collection of cars, which has one car: code="bmw",Type.Van But... Application with webrefence receives the same collection and application with servicereference gets collection, where field code is null... Invoking servicereference: MyService myService=new MyService() Cars[] cars= client.GetCars(carcode); Invoking webservice: MyService.MyServiceSoapClient client = new MyServiceS.MyServiceSoapClient(); Cars[] cars= client.GetCars(carcode);

  • Frustrated with Objective-c code...

    - by Moshe
    Well, I've started with iPod/iPhone programming using Head First iPhone Development (O'reilly) and I'm typing code out of the book. There are two problems, one is programming related and the other is not. I don't understand the format of objective-c methods. I'm getting an few errors now, based on source code from the book. Which leads me to my next issue. Some of the code is buggy. I think so because I couldn't get the code to run without modifying it. The book has some typos in the text since it's a first edition and whatnot, but could my "fixing" the code have to do with it? So... Where can I learn more about objective-c methods and how they work in terms of structure and where the return type and arguments go? For those with the book, I'm in the middle of the InstaTweet app towards the beginning. Thanks.

  • ruby syntactic sugar: dealing with nils..

    - by luca
    probably asked already but I couldn't find it.. here are 2 common situation (for me while programming rails..) that are frustrating to write in ruby: "a string".match(/abc(.+)abc/)[1] in this case I get an error because the string doesn't match, therefore the [] operator is called upon nil. What I'd like to find is a nicer alternative to the following: temp="a string".match(/abc(.+)abc/); temp.nil? ? nil : temp[1] in brief, if it didn't match simply return nil without the error The second situation is this one: var = something.very.long.and.tedious.to.write var = something.other if var.nil? In this case I want to assign something to var only if it's not nil, in case it's nil I'll assign something.other.. Any suggestion? Thanks!

  • Is it possible to tell IIS 7 to process the request queue in parallel?

    - by Uwe Keim
    Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run. Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool. But we experience quiet the opposite: When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc. Question: Is it possible (without changing the C# code of the web service) to configure IIS to process requests in parallel, if enough threads are available? If yes: how should I do it? It no: any workarounds/tips? Thanks Uwe

  • problems with user control page

    - by Alexander
    I am starting to give up troubleshooting this issue I had... I had an .ascx page and had the following user control in it: <td> <Club:DatePicker ID="dp1" runat="server" /> </td> however in my code behind when I tried to write methods: public System.DateTime startDateTime { get { return dp1.SelectedDate.Add(tp1.SelectedTime.TimeOfDay); } set { dp1.SelectedDate = value; tp1.SelectedTime = value; } } It can't reference dp1(dp1 is underlined in red) as well as tp1... why is this?? I've tried to convert the solution to a web application and yet it doesn't work. Tried adding: protected global::ClubSite dp1; protected global::ClubSite tp1; in the ascx.designer.cs but then the global is highlighted in red here's the link to my full solution: http://cid-1bd707a1bb687294.skydrive.live.com/self.aspx/.Public/Permias.zip

  • Getting ID of an instance newly launched with ec2-api-tools

    - by Jonik
    I'm launching an EC2 instance, by invoking ec2-run-instances from simple a bash script, and want to perform further operations on that instance (e.g. associate elastic IP), for which I need the instance id. The command is something like ec2-run-instances ami-dd8ea5a9 -K pk.pem -C cert.pem --region eu-west-1 -t c1.medium -n 1, and its output: RESERVATION r-b6ea58c1 696664755663 default INSTANCE i-945af9e3 ami-dd8ea5b9 pending 0 c1.medium 2010-04-15T10:47:56+0000 eu-west-1a aki-b02a01c4 ari-39c2e94d In this example, i-945af9e3 is the id I'm after. So, I'd need a simple way to parse the id from what the command returns - how would you go about doing it? My AWK is a little rusty... Feel free to use any tool available on a typical Linux box. (If there's a way to get it directly using EC2-API-tools, all the better. But afaik there's no EC2 command to e.g. return the id of the most recently launched instance.)

  • jQuery AJAX not redirecting?

    - by MidnightLightning
    I have a simple PHP page (for testing) that simply calls header("Location: http://www.example.com");exit;, which resides on the same server, in the same directory as another file with the following jQuery Javascript: $(document).ready(function() { jQuery.ajax({ type : 'GET', url : 'bounce.php', error : function(xhr, status, error) { console.log("ERROR: ", xhr, xhr.status, xhr.getAllResponseHeaders()); }, complete : function(xhr, status) { // Get headers of the response console.log("COMPLETE: ", xhr, xhr.status, xhr.getAllResponseHeaders()); } }); }); I was expecting (from several other StackOverflow responses) for the xhr.status to return "302", but instead the AJAX call is triggering the "error" event (and then the "complete" event), and xhr.status is returning 0 (zero), and .getAllResponseHeaders() is coming back null (in both the error, and complete functions). Firebug is showing the "302 Moved Temporarily", and the response headers. So why is this triggering the error event, and not passing along the proper 302 code, and headers? Is this something to do with the Same Origin since the bouncing script and the fetching script are both on the same server? Is this jQuery or Javascript's fault?

  • Silverlight -> WCF -> Database -> problem

    - by Billy
    Hi there, I have some silverlight code that calls a WCF service which then uses the Entity Framework to access the database and return records. Everything runs fine but ... when I replace the Entity Framework code with classic ADO.NET code I get an error: The remote server returned an error: NotFound When I call the ADO.NET code directly with a unit test it returns records fine so it's not a problem with the ADO.NEt code I used fiddler and it seems to say that the service cannot be found with a "500" error. i don't think it's anything to do with the service as the only thing I change is the technology to access the database. Anyone know what i'm missing here?

  • c# Active Directory via WMI

    - by Juri Bogdanov
    Hi! Does anyone has some example about accessing Active Directory, LDAP querying using WMI (System.Management namespace) and not System.DirectoryServices namespace. Here on MSDN page it is described a little using CIM classes http://msdn.microsoft.com/en-us/library/aa392320(v=VS.85).aspx But I cant find some C# example realizing it. For example, to access some Win32 class you have to initialize Scope object to use CIMV2 namespace private ConnectionOptions connection; private ManagementScope scope; ... connection = new ConnectionOptions(); ... scope = new ManagementScope("\\\\" + computer + "\\root\\CIMV2", connection); try { scope.Connect(); } And use ObjectQuery class for querying WMI data ObjectQuery objectQuery = new ObjectQuery("SELECT Name FROM Win32_Processor"); ManagementObjectSearcher searcher = ManagementObjectSearcher(scope, objectQuery); foreach (ManagementObject queryObj in searcher.Get()) { return queryObj["Name"].ToString(); } How is it possible to access AD using the same scope? Thanks :)

  • How can I get this code involving unique_ptr and emplace_back to compile?

    #include <vector> #include <memory> using namespace std; class A { public: A(): i(new int) {} A(A const& a) = delete; A(A &&a): i(move(a.i)) {} unique_ptr<int> i; }; class AGroup { public: void AddA(A &&a) { a_.emplace_back(move(a)); } vector<A> a_; }; int main() { AGroup ag; ag.AddA(A()); return 0; } does not compile... (says that unique_ptr's copy constructor is deleted) I tried replacing move with forward. Not sure if I did it right, but it didn't work for me.

  • OSCommerce checkout success page tracking

    - by Neil Bradley
    Hi there, I'm installing some tracking code into the checkout_success.php page. I need to be able to grab the coupon code/discount code name from the order, if one was used so that I can echo it out in my tracking script. I was wondering if anyone knows how to do this? I'm using this contribution of discount coupons; ot_discount_coupons.php, August 4, 2006, author: Kristen G. Thorson, ot_discount_coupon_codes version 3.0 It seems that the coupon code is not actually stored in the order_totals, but in a seperate discount_coupons_to_orders table. is there a query i can do on this table to find the matching coupon code used for this order? i tried the following but it return nothing; $coupon_query = tep_db_query("select coupons_id from discount_coupons_to_orders where orders_id = '".(int)$orders['orders_id']."' ORDER BY orders_id DESC LIMIT 1"); $coupon_id = tep_db_fetch_array($coupon_query); $couponid = $coupon_id['coupon_id']; Thank you.

  • Where are config files for class libraries physically located?

    - by BadNinja
    My guess is that this question will fall under the category of "duh", but, nevertheless, I'm confused. When using config files in, for example, a Windows Forms Application, the config file can be found in C:\Program files\CompanyName\ProductName\Application.exe.config. However, with the class library I'm developing I do not see a "ClassLibrary.dll.config" file in the install folder after installing it (in tandem with another project) from Visual Studio. Even though I do not see the file anywhere, retrieving data from it works correctly. Plus, running the following code from a method within the class library returns the path you would expect: C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config. If someone could shed some light on what I'm missing here, that would be really awesome. public static string MyMethod() { Assembly assem = Assembly.GetExecutingAssembly(); Configuration config = ConfigurationManager.OpenExeConfiguration(assem.Location); return "The assembly location was: " + assem.Location + Environment.NewLine + "The config file path was: " + config.FilePath; // Gives me "C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config" }

  • Modifying CollectionEditor in PropertyGrid

    - by Chris
    I currently have a list containing Call's, which is the base class. If I want to add derived classes of Call to the list, I know to do the following. public class CustomCollectionEditor : System.ComponentModel.Design.CollectionEditor { private Type[] types; public CustomCollectionEditor(Type type) : base(type) { types = new Type[] { typeof(Call), typeof(CappedCall) }; } protected override Type[] CreateNewItemTypes() { return types; } } public class DisplayList { public DisplayList() { } [Editor(typeof(CustomCollectionEditor), typeof(UITypeEditor))] [DataMember] public List<Call> ListCalls { get; set; } } My questions is there anyway of moving where you mark up the Type[] containing all possible types the list can contain? I thought of adding the following to my CustomCollectionEditor class, but this doesn't work. public CustomCollectionEditor(Type type, List<Type> types_) : base(type) { types = types_.ToArray(); } It would be ideal if I could mark up which classes the CustomCollectionEditor needed to be aware of in the DisplayList class somehow.

  • Inheritance of Custom Attributes on Abstract Properties

    - by Marty Trenouth
    I've got a custom attribute that I want to apply to my base abstract class so that I can skip elements that don't need to be viewed by the user when displaying the item in HTML. It seems that the properties overriding the base class are not inheriting the attributes. Does overriding base properties (abstract or virtual) blow away attributes placed on the original property? From Attribute class Defination [AttributeUsage(AttributeTargets.Property, Inherited = true, AllowMultiple = false)] public class NoHtmlOutput : Attribute { } From Abstract Class Defination [NoHtmlOutput] public abstract Guid UniqueID { get; set; } From Concrete Class Defination public override Guid UniqueID{ get{ return MasterId;} set{MasterId = value;}} From class checking for attribute Type t = o.GetType(); foreach (PropertyInfo pi in t.GetProperties()) { if (pi.GetCustomAttributes(typeof(NoHtmlOutput), true).Length == 1) continue; // processing logic goes here }

  • Returning Index in Enumerable Select

    - by Jon
    I have a List<MyClass> with 2 items which have a SequenceNumber property. If I use this code below the returned index is 0 not 1: var test = TrackingCollection .Where(x => x.SequenceNumber == 2) .Select((item, index) => new { index, item.SequenceNumber }); Is this because that refers to 0 as the index in my new anonymous type or is it some zero index based weirdness that I just need to increment. What I'm after is to return the index in TrackingCollection where the sequence number is 2 or 887 or any other correct index in the original collection...

  • C# .NET 4.0 and Generics

    - by Mr Snuffle
    I was wondering if anyone could tell me if this kind of behaviour is possible in C# 4.0 I have an object hierarchy I'd like to keep strongly typed. Something like this class ItemBase {} class ItemType<T> where T : ItemBase { T Base { get; set; } } class EquipmentBase : ItemBase {} class EquipmentType : ItemType<EquipmentBase> {} What I want to be able to do to have something like this ItemType item = new EquipmentType(); And I want item.Base to return type ItemBase. Basically I want to know if it's smart enough to strongly typed generic to a base class without the strong typing. Benefit of this being I can simply cast an ItemType back to an EquipmentType and get all the strongly typedness again. I may be thinking about this all wrong...
