  • Validation Summary for Collections

    - by Myster
    Hi All, EDIT: upgraded this question to MVC 2.0 With asp.net MVC 2.0 is there an existing method of creating Validation Summary that makes sense for models containing collections? If not I can create my own validation summary Example Model: public class GroupDetailsViewModel { public string GroupName { get; set; } public int NumberOfPeople { get; set; } public List<Person> People{ get; set; } } public class Person { [Required(ErrorMessage = "Please enter your Email Address")] [RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", ErrorMessage = "Please enter a valid Email Address")] public string EmailAddress { get; set; } [Required(ErrorMessage = "Please enter your Phone Number")] public string Phone { get; set; } [Required(ErrorMessage = "Please enter your First Name")] public string FirstName { get; set; } [Required(ErrorMessage = "Please enter your Last Name")] public string LastName { get; set; } } The existing summary <%=Html.ValidationSummary %> if nothing is entered looks like this. The following error(s) must be corrected before proceeding to the next step * Please enter your Email Address * Please enter your Phone Number * Please enter your First Name * Please enter your Last Name * Please enter your Email Address * Please enter your Phone Number * Please enter your First Name * Please enter your Last Name The design calls for headings to be inserted like this: The following error(s) must be corrected before proceeding to the next step Person 1 * Please enter your Email Address * Please enter your Phone Number * Please enter your First Name * Please enter your Last Name Person 2 * Please enter your Email Address * Please enter your Phone Number * Please enter your First Name * Please enter your Last Name

  • Partial mapping in Entity Framework 4

    - by Dimi Toulakis
    Hi guys, I want to be able to do the following: I have a model and inside there I do have an entity. This entity has the following structure: public class Client { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } What I want now, is to just get the client name based on the id. Therefore I wrote a stored procedure which is doing this. CREATE PROCEDURE [Client].[GetBasics] @Id INT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; SELECT Name FROM Client.Client INNER JOIN Client.Validity ON ClientId = Client.Id WHERE Client.Id = @Id; END Now, going back to VS, I do update the model from the database with the stored procedure included. Next step is to map this stored procedure to the client entity as a function import. This also works fine. Trying now to load one client's name results into an error during runtime... "The data reader is incompatible with the specified 'CSTestModel.Client'. A member of the type, 'Id', does not have a corresponding column in the data reader with the same name." I am OK with the message. I know how to fix this (returning as resultset Id, Name, Description). My idea behind this question is the following: I just want to load parts of the entity, not the complete entity itself. Is there a solution to my problem (except creating complex types)? And if yes, can someone point me to the right direction? Many thanks, Dimi

  • how to create and track multiple pairs "View-ViewModel"?

    - by Gianluca Colucci
    Hi! I am building an application that is based on MVVM-Light. I am in the need of creating multiple instances of the same View, and each one should bind to its own ViewModel. The default ViewModelLocator implements ViewModels as singletons, therefore different instances of the same View will bind to the same ViewModel. I could create the ViewModel in the VMLocator as a non-static object (as simple as returning new VM()...), but that would only partially help me. In fact, I still need to keep track of the opened windows. Nevertheless, each window might open several other windows (of a different kind, though). In this situation I might need to execute some operation on the parent View and all its children. For example before closing the View P, I might want to close all its children (view C1, view C2, etc.). Hence, is there any simple and easy way to achieve this? Or is there any best practice you would advice me to follow? Thanks in advance for your precious help. Cheers, Gianluca.

  • .NET EventHandlers - Generic or no?

    - by Chris Marasti-Georg
    Every time I start in deep in a C# project, I end up with lots of events that really just need to pass a single item. I stick with the EventHandler/EventArgs practice, but what I like to do is have something like: public delegate void EventHandler<T>(object src, EventArgs<T> args); public class EventArgs<T>: EventArgs { private T item; public EventArgs(T item) { this.item = item; } public T Item { get { return item; } } } Later, I can have my public event EventHandler<Foo> FooChanged; public event EventHandler<Bar> BarChanged; However, it seems that the standard for .NET is to create a new delegate and EventArgs subclass for each type of event. Is there something wrong with my generic approach? EDIT: The reason for this post is that I just re-created this in a new project, and wanted to make sure it was ok. Actually, I was re-creating it as I posted. I found that there is a generic EventHandler<TEventArgs, so you don't need to create the generic delegate, but you still need the generic EventArgs<T class, because TEventArgs: EventArgs. Another EDIT: One downside (to me) of the built-in solution is the extra verbosity: public event EventHandler<EventArgs<Foo>> FooChanged; vs. public event EventHandler<Foo> FooChanged; It can be a pain for clients to register for your events though, because the System namespace is imported by default, so they have to manually seek out your namespace, even with a fancy tool like Resharper... Anyone have any ideas pertaining to that?

  • Date since 1600 to NSDate?

    - by Steven Fisher
    I have a date that's stored as a number of days since January 1, 1600 that I need to deal with. This is a legacy date format that I need to read many, many times in my application. Previously, I'd been creating a calendar, empty date components and root date like this: self.gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar ] autorelease]; id rootComponents = [[[NSDateComponents alloc] init] autorelease]; [rootComponents setYear: 1600]; [rootComponents setMonth: 1]; [rootComponents setDay: 1]; self.rootDate = [gregorian dateFromComponents: rootComponents]; self.offset = [[[NSDateComponents alloc] init] autorelease]; Then, to convert the integer later to a date, I use this: [offset setDay: theLegacyDate]; id eventDate = [gregorian dateByAddingComponents: offset toDate: rootDate options: 0]; (I never change any values in offset anywhere else.) The problem is I'm getting a different time for rootDate on iOS vs. Mac OS X. On Mac OS X, I'm getting midnight. On iOS, I'm getting 8:12:28. (So far, it seems to be consistent about this.) When I add my number of days later, the weird time stays. OS | legacyDate | rootDate | eventDate ======== | ========== | ==========================|========================== Mac OS X | 143671 | 1600-01-01 00:00:00 -0800 | 1993-05-11 00:00:00 -0700 iOS | 143671 | 1600-01-01 08:12:28 +0000 | 1993-05-11 07:12:28 +0000 In the previous release of my product, I didn't care about the time; now I do. Why the weird time on iOS, and what should I do about it? (I'm assuming the hour difference is DST.) I've tried setting the hour, minute and second of rootComponents to 0. This has no impact. If I set them to something other than 0, it adds them to 8:12:28. I've been wondering if this has something to do with leap seconds or other cumulative clock changes. Or is this entirely the wrong approach to use on iOS?

  • AST with fixed nodes instead of error nodes in antlr

    - by ahe
    I have an antlr generated Java parser that uses the C target and it works quite well. The problem is I also want it to parse erroneous code and produce a meaningful AST. If I feed it a minimal Java class with one import after which a semicolon is missing it produces two "Tree Error Node" objects where the "import" token and the tokens for the imported class should be. But since it parses the following code correctly and produces the correct nodes for this code it must recover from the error by adding the semicolon or by resyncing. Is there a way to make antlr reflect this fixed input it produces internally in the AST? Or can I at least get the tokens/text that produced the "Tree Node Errors" somehow? In the C targets antlr3commontreeadaptor.c around line 200 the following fragment indicates that the C target only creates dummy error nodes so far: static pANTLR3_BASE_TREE errorNode (pANTLR3_BASE_TREE_ADAPTOR adaptor, pANTLR3_TOKEN_STREAM ctnstream, pANTLR3_COMMON_TOKEN startToken, pANTLR3_COMMON_TOKEN stopToken, pANTLR3_EXCEPTION e) { // Use the supplied common tree node stream to get another tree from the factory // TODO: Look at creating the erronode as in Java, but this is complicated by the // need to track and free the memory allocated to it, so for now, we just // want something in the tree that isn't a NULL pointer. // return adaptor->createTypeText(adaptor, ANTLR3_TOKEN_INVALID, (pANTLR3_UINT8)"Tree Error Node"); } Am I out of luck here and only the error nodes the Java target produces would allow me to retrieve the text of the erroneous nodes?

  • Java equivalent to VS solution file

    - by Chris
    I'm a C# guy trying to learn Java. I understand the syntax and the basic architecture of the Java platform, and have no problem doing smaller projects myself, but I'd really like to be able to download some open source projects to learn from the work of others. However, I'm running into a stumbling block that I can't seem to find any information on. When I download an open source .NET project, I can open the .sln file with visual studio and everything just loads. Sure, there's occasionally a missing reference or something, but there's really very little configuration required to get things going. I'm not sensing the same ease of use with Java. I'm using eclipse at the moment, and it feels like for every project I have to create a brand new Eclipse project using "create from existing source", and almost nothing compiles properly without significant reconfiguration. In the case of web projects, it's even worse, because Eclipse doesn't appear to support creating a web project from existing source. I have to create a standard Java project from source, then then apparently modify the project file to include the bindings for the web toolkit stuff to work properly. Assuming I want to be able to contribute to a project later on, I shouldn't have to be making such drastic changes to the file structure to get my IDE to a workable state. What am I missing?

  • running bash scripts in php

    - by HDawg
    I have two computers. On the first computer I have apache running with all my web code. On the second computer I have large amounts of data stored with a retrieval script (the script usually takes hours to run). I am essentially creating a web UI to access this data without any time delay. so I call: exec("bash initial.bash"); this is a driver script that is in my Apache folder. It calls the script on the other computer. calling: ssh otherMachine temp.bash& this script invokes the data retrieval script on the second computer. If I call initial.bash in the terminal, everything works smoothly and successfully, but if I call it in my PHP file, then all my commands in initial.bash run, with the exception of ssh otherMachine temp.bash&. I put the & at the end of that, so that temp.bash will run in the background, since it does take a few hours to complete. I am not sure why the nested script is not running when invoked by Apache. Is there a better alternative than using exec or shell_exec to call a script, which ultimately calls another script. The reason I don't call a script on the second machine directly is because of the time it takes the program to run. Shell_exec does not render the php page until the script is complete.

  • How to create a folder under %allusersprofile% during Setup with VS 2003 Setup Project?

    - by Romias
    I need to create a folder under "%allusersprofile%/Program Data" during the install process. The Setup file is created with VS 2003 setup project, and in it you can use several Known Folders... but as I see none maps to %allusersprofile% or "%allusersprofile%/Program Data". I thought that creating a "Custom Folder" (within VS Setup Project) and setting the TargetLocation as %allusersprofile% it would work, but during install it says that I don't have permission to that folder (and I do have). Do you know how to target that folder in VS Setup Project? Also... I'm working in Windows XP, so %allusersprofile% maps to "C:\Documents and Settings\All Users", but there I suppose I should create my folder inside the "Program Data" folder. In Vista, %allusersprofile% maps to "C:\ProgramData" and it look correct if I create my folder directly there. Any idea how to target both OSs? Additional info: I'm trying this to avoid the new security features in Vista, where the app can't write files under the Program Files folder when running as a common user at least. So I need to place the writable files on "common" folder that is not in a "per user" basis.

  • IHttpAsyncHandler and IObservable web requests

    - by McLovin
    Within Async handler I'm creating an IObservable from webrequest which returns a redirect string. I'm subscribing to that observable and calling AsyncResult.CompleteCall() but I'm forced to use Thread.Sleep(100) in order to get it executed. And it doesn't work every time. I'm pretty sure this is not correct. Could you please shine some light. Thank you! public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object state) { _context = context; _ar = new AsyncResult(cb, state); _tweet = context.Request["tweet"]; string url = context.Request["url"]; if(String.IsNullOrEmpty(_tweet) || String.IsNullOrEmpty(url)) { DisplayError("<h2>Tweet or url cannot be empty</h2>"); return _ar; } _oAuth = new oAuthTwitterRx(); using (_oAuth.AuthorizationLinkGet().Subscribe(p => { _context.Response.Redirect(p); _ar.CompleteCall(); }, exception => DisplayError("<h2>Unable to connect to twitter, please try again</h2>") )) return _ar; } public class AsyncResult : IAsyncResult { private AsyncCallback _cb; private object _state; private ManualResetEvent _event; private bool _completed = false; private object _lock = new object(); public AsyncResult(AsyncCallback cb, object state) { _cb = cb; _state = state; } public Object AsyncState { get { return _state; } } public bool CompletedSynchronously { get { return false; } } public bool IsCompleted { get { return _completed; } } public WaitHandle AsyncWaitHandle { get { lock (_lock) { if (_event == null) _event = new ManualResetEvent(IsCompleted); return _event; } } } public void CompleteCall() { lock (_lock) { _completed = true; if (_event != null) _event.Set(); } if (_cb != null) _cb(this); } }

  • What are some techniques to monitor multiple instances of a piece of software?

    - by Geo Ego
    I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status directly. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

  • Nav Controller, UITableViewController, UITextField to become firstResponder?

    - by Daniel Granger
    I have a core data application which uses a navigation controller to drill down to a detail view and then if you edit one of the rows of data in the detail view you get taken to an Edit View for the that single line, like in Apples CoreDataBooks example! The edit view is a UITableviewController which creates its table with a single section single row and a UITextfield in the cell, programatically. What I want to happen is when you select a row to edit and the edit view is pushed onto the nav stack and the edit view is animated moving across the screen, I want the textfield to be selected as firstResponder so that the keyboard is already showing as the view moves across the screen to take position. Like in the Contacts app or in the CoreDataBooks App. I currently have the following code in my app which causes the view to load and then you see the keyboard appear (which isn't what I want, I want the keyboard to already be there) - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [theTextField becomeFirstResponder]; } You can't put this in -viewWillAppear as the textfield hasn't been created yet so theTextField is nil. In the CoreDataBooks App where they achieve what i want they load there tableview from a nib so they use the same code but in -viewWillAppear as the textfield has already been created! Is there anyway of getting around this without creating a nib, I want to keep the implementation programatic to enable greater flexibility. Many Thanks

  • Should an Event that has no arguments define its own custom EventArgs or simply use System.EventArgs

    - by Mike Rosenblum
    I have an event that is currently defined with no event arguments. That is, the EventArgs it sends is EventArgs.Empty. In this case, it is simplest to declare my Event handler as: EventHandler<System.EventArgs> MyCustomEvent; I do not plan on adding any event arguments to this event, but it is possible that any code could need to change in the future. Therefore, I am leaning towards having all my events always create an empty event args type that inheretis from System.EventArgs, even if there are no event args currently needed. Something like this: public class MyCustomEventArgs : EventArgs { } And then my event definition becomes the following: EventHandler<MyCustomEventArgs> MyCustomEvent; So my question is this: is it better to define my own MyCustomEventArgs, even if it does not add anything beyond inheriting from System.EventArgs, so that event arguments could be added in the future more easily? Or is it better to explicitly define my event as returning System.EventArgs, so that it is clearer to the user that there are no extra event args? I am leaning towards creating custom event arguments for all my events, even if the event arguments are empty. But I was wondering if others thought that making it clearer to the user that the event arguments are empty would be better? Much thanks in advance, Mike

  • XMLBeans - xsi:type stripped using Axis2 and Tomcat?

    - by Matthew Gamble
    I’m new to XMLBeans and have been trying to use it to create an XML document as part of an axis2 web service. When I run my code as a standard Java application or as a standard servlet, the XML is correctly generated: <?xml version="1.0" encoding="UTF-8"?> <c:BroadsoftDocument protocol="OCI" xmlns:c="C"> <sessionId>000000001</sessionId> <command xsi:type="AuthenticationRequest" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <userId>admin</userId></command> </c:BroadsoftDocument> However, when the exact same code is run under Axis2 & Tomcat in a servlet I get: <?xml version="1.0" encoding="UTF-8"?> <c:BroadsoftDocument protocol="OCI" xmlns:c="C"> <sessionId>000000001</sessionId> <command> <userId>admin</userId></command> </c:BroadsoftDocument> This of course isn’t valid – the xsi:type of the “command” element is stripped when the code is run under Tomcat. Does anyone have any suggestions of what I could be doing wrong that would cause this type of issue only when running under Axis2? At first I thought it was a Tomcat issue, but after creating a generic servlet and running the exact same code I don't have any issues. I've tried playing with the XMLOptions for XMLBeans, but couldn't seem to resolve the problem. The options I'm currently using are: xmlOptions = new XmlOptions(); xmlOptions.setCharacterEncoding("UTF-8"); xmlOptions.setUseDefaultNamespace(); xmlOptions.setSaveAggressiveNamespaces(); xmlOptions.setSavePrettyPrint();

  • Infopath - Repeating sections

    - by witsEnd
    I have struggled with this for 2 days and posted this question at a couple of other sites but with no luck. I am creating a form as follows. I have an "outer" repeating section in which the user enters a work item id and then selects as many names as he/she wishes from a series of drop down lists. When the user clicks a button (also in this "outer" repeating section), Feedback textboxes are added for each name selected, as well as text boxes with the names selected from the drop down appear above the those provided for feedback. I used the XPathNavigator.Clone() method to create the new feedback textboxes and textboxes that display the user's name that was selected. (The username textbox appears above the respective feedback textbox). This did the trick, but there is a problem. The user should be able to click "Insert item" on the outer repeating section to add another work item wherein he/she may again select as many names as they wish from the series of drop downs, click a button, and have feedback and user name text boxes appear for each name selected from the drop down box associated with the current work item, (i.e, "outer" repeating section). I clicked Insert Item on the "outer" repeating section and selected 2 names from the second series of drop downs, but when I try to clone a node, it is added at the end of the previous repeating section. I don't know how to navigate into (for lack of a better term) subsequent repeating sections. I am using InfoPath 2007 and I am aware that the current() method call is implicit, but this still doesn't work. I'm thinking I need to set up a Rule somewhere, but I am not sure how to do that. Any help would be appreciated.

  • Is there any special tool for interactive GUI development

    - by niko
    Hi, Currently I am preparing exercises about networks and mobile communications for students. I was thinking about creating an interactive user-interface which enables the user to drag&drop predefined elements and then implement a logic based upon element distances etc. An example would be to place two base stations (a predefined element with several properties), set the scale in the interface and then check the signal interferrence in the environment (user-interface). The first part might be too abstract whereas the example might be too specific, but I was wondering whether there already exists any friendly framework or language which enables developers to create interactive interfaces (for teaching/learning purpouses) in short ammount of time. Usually I write applications for PC environment in .NET but in this case it would take too much time to create a specific interface for every exercise. I would appreciate if anyone could suggest any way to create interactive user-interface in short ammount of time. Are there any special programming languages or development tools for this kind of applications or are there any useful frameworks for .NET, Java or any other language to speed up the development of user-interfaces? Thank you!

  • Populating JavaScript Array from JSP List

    - by tkeE2036
    Ok so perhaps someone can help me with a problem I'm trying to solve. Essentially I have a JSP page which gets a list of Country objects (from the method referenceData() from a Spring Portlet SimpleFormController, not entirely relevant but just mentioning in case it is). Each Country object has a Set of province objects and each province and country have a name field: public class Country { private String name; private Set<Province> provinces; //Getters and setters } public class Province { private String name; //Getters and setters } Now I have two drop down menus in my JSP for countries and provinces and I want to filter the provinces by country. I've been following this tutorial/guide to make a chain select in JavaScript. Now I need a dynamic way to create the JavaScript array from my content. And before anyone mentions AJAX this is out of the question since our project uses portlets and we'd like to stay away from using frameworks like DWR or creating a servlet. Here is the JavaScript/JSP I have so far but it is not populating the Array with anything: var countries = new Array(); <c:forEach items="${countryList}" var="country" varStatus="status"> countries[status.index] = new Array(); countries[status.index]['country'] = ${country.name}; countries[status.index]['provinces'] = [ <c:forEach items="${country.provinces}" var="province" varStatus="provinceStatus"> '${province.name}' <c:if test="${!provinceStatus.last}"> , </c:if> </c:forEach> ]; </c:forEach> Does anyone know how to create an JavaScript array in JSP in the case above or what the 'best-practice' would be considered in this case? Thanks in advance!

  • Exporting non-public type through public API

    - by feelgood
    What if I have few factory methods returning non-public type and pairing set of methods which gives variables of this non-public type? This results with titled warning message in NetBeans. In result public API will contain only two pairing sets of methods. The reason is to make my type hierarchy sealed (like seald classes in Scala) and allow users only instantiate these types through factory methods. So we get DSL in some sense. For example, Schedule class represented by calendar fields' contraints. There are some types of contraints - Range, Singleton, List, FullSet - with NumberSet interface as a root. We don't want to expose these types and how Schedule interact with them. We just want the specification from the user. So we make NumberSet package-private. In class Schedule we create few factory-methods for constraints: NumberSet singleton(int value); NumberSet range(int form, int to); NumberSet list(NumberSet ... components); and some methods for creating Schedule object: Schedule everyHour(NumberSet minutes); Schedule everyDay(NumberSet minutes, NumberSet hours); User can only use them in the manner: Schedule s = Schedule.everyDay( singleton(0), list(range(10-15), singleton(8)) ); Is it bad idea?

  • Create a SSL certificate on Windows

    - by Ben Fransen
    Hi all, Since I'm very new to SSL certificates, and the creation and usage of them I figured maybe StackOverflow members can help me out. I'm from Holland, the common way of online payments is by implementing iDEAL. An online payment protocol supported by the major banks. I have to implement a 'professional' version. This includes creating a RSA private key. Based on that key I have to create a certificate and upload it to the webserver. I'm on a Windows machine and completely confused what to do. I took a look at the OpenSSL website, because the manual forwarded me to that website to get a SSL Toolkit. The manual provides two commands which have to be executed in order to create a RSA key and a certificate. The commands are: openssl genrsa -des3 –out priv.pem -passout pass:myPassword 1024 and openssl req -x509 -new -key priv.pem -passin pass:myPassword -days 3650 -out cert.cer Is there a way I can do this by a utility on a windows machine? I've downloaded PuTTy KeyGenerator. But I'm not sure what to do, I've created a key (SSH-2 RSA, whatever that is..) but how do I create a certificate with that key? Any help is much appreciated! Ben

I need to find error first . . . why : Error message parser: Error creating configuration section handler for FlowWebDataProviders: Could not load type 'FlowWebProvidersSection'. ? by the way : syntax of nemerle (current language) is very similar C#, don't afraid to read the code... thank you

  • Can't get NUnit to work in Visual Web Develper 2010 express.

    - by UkraineTrain
    First off I was wondering whether it's possible to implement a functionality with Nunit where each time a project is created in Visual Web Developer 2010 I get a dialog asking whether I want to create a unit test project for current application like I saw it happen in the older versions of Visual Web Developer. I've tried just about everything to get NUnit 2.5.5 to work in Visual Web Developer 2010. For example, in nunit.exe.config I added under configuration <startup> <requiredRuntime version="v4.0.30319" /> </startup> and under runtime: <loadFromRemoteSources enabled="true" /> I then tried to launch nunit-console.exe in order to specify in the command line the option /framework=net-4.0, but the console would appear and instantly disappear. It didn't help when I tried running it as an administrator. I've also tried using Nunit as an external tool inside the Visual Web Developer by creating a toolbar as described in the following link: http://www.marthijnvandenheuvel.com/2010/06/09/using-nunit-in-visual-studio-2010/. It shows up as an icon in the toolbar. I ran my project called ToyStore and then clicked Nunit icon in order to launch it and it gave me a "System.IO.FileNotFoundException:Assembly not found:ToyStore.dll". So, needless to say, I'm pretty lost and don't know what to do and would greatly appreciate any help in getting Nunit to work.

  • Benchmarking a UDP server

    - by Nicolas
    I am refactoring a UDP listener from Java to C. It needs to handle between 1000 and 10000 UDP messages per second, with an average data length of around 60 bytes. There is no reply necessary. Data cannot be lost (Don't ask why UDP was decided). I fork off a process to deal with the incoming data so that I can recvfrom as quickly as possible - without filling up my kernel buffers. The child then handles the data received. In short, my algo is: Listen for data. When data is received, check for errors. Fork off a child. If I'm a child, do what I with the data and exit. If I'm a parent, reap any zombie children waitpid(-1, NULL, WNOHANG). Repeat. Firstly, any comments about the above? I'm creating the socket with socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP), binding with AF_INET and INADDR_ANY and recvfrom with no flags. Secondly, can anyone suggest something that I can use to test that this application (or at least the listener) can handle more messages than what I am expecting? Or, would I need to hack something together to do this. I'd guess the latter would be better, so that I can compare data that is generated versus data that is received. But, comments would be appreciated.
