  • Using a Cross Thread Boolean to Abort Thread

    - by Jon
    Possible Duplicate: Can a C# thread really cache a value and ignore changes to that value on other threads? Lets say we have this code: bool KeepGoing = true; DataInThread = new Thread(new ThreadStart(DataInThreadMethod)); DataInThread.Start(); //bla bla time goes on KeepGoing = false; private void DataInThreadMethod() { while (KeepGoing) { //Do stuff } } } Now the idea is that using the boolean is a safe way to terminate the thread however because that boolean exists on the calling thread does that cause any issue? That boolean is only used on the calling thread to stop the thread so its not like its being used elsewhere

  • Track/Display Array Index As Part Of Cout (C++)

    - by John Smith
    Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

  • How to auto create a JMS topic/queue on JBoss in a portable and per-application way?

    - by Bozho
    It's simple: I have an MDB and an EJB that sends messages to a topic (or queue). JBoss complains that the topic is not bound to the JNDI context. I want to have the topic/queue to be automatically created at best, or at least to have a standard way to define it, per application (say, in ejb-jar/META-INF) this question and this blogpost show us how to do it in an application server specific way. This surely works, but: I want to use the @MessageDriven annotation I want the setting not to be global for the application server I want the setting to be portable

  • I Clean Solution'd my Winform App and now it's broken...

    - by Refracted Paladin
    I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -- Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded also if I try to open a form or user control in Design Mode I first get this -- could not find type, "MyType" please make sure that the assembly that contains this type is referenced and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode -- Exception of type System.OutOfMemoryException was thrown Help!?!? When I googled I came across mostly references to VS 2003...I am on 2008 sp1.

  • Ajax Control Toolkit CalendarExtender not closing when form body clicked.

    - by TampaRich
    I am trying to simply have the calendar close when a user clicks anywhere on the page. I have downloaded the most recent version of the toolkit and I can not get this functionality to work. I am not sure if I am missing a property but the functionality works as expected on the asp.net sample toolkit page. Here is the code: <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </asp:ToolkitScriptManager> <asp:TextBox ID="txtTest" runat="server" /><img runat="server" alt="Calendar" id="imgCalFrom" align="absmiddle" border="0" height="16" src="/global/images/glo_btn_cal.gif" width="21"/> <asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txtTest" PopupButtonID="imgCalFrom"> </asp:CalendarExtender>

  • How can I use a config-file in Expression Blend 4?

    - by sofri
    Hi, while trying to use the "InfoStrat"-Bing-Maps-Control in Expression Blend 4 for my Surface Application, I get the error message: "Mixed mode assembly is built against version v2.0.50527 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information" I already found out that I need to write this configfile: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> But Expression Blend doesn't seem to recognize that it is there. So how can I solve this problem?

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • Long polling with NSURLConnection

    - by pix0r
    I'm working on an iPhone application which will use long-polling to send event notifications from the server to the client over HTTP. After opening a connection on the server I'm sending small bits of JSON that represent events, as they occur. I am finding that -[NSURLConnectionDelegate connection:didReceiveData] is not being called until after I close the connection, regardless of the cache settings I use when creating the NSURLRequest. I've verified that the server end is working as expected - the first JSON event will be sent immediately, and subsequent events will be sent over the wire as they occur. Is there a way to use NSURLConnection to receive these events as they occur, or will I need to instead drop down to the CFSocket API? I'm starting to work on integrating CocoaAsyncSocket, but would prefer to continue using NSURLConnection if possible as it fits much better with the rest of my REST/JSON-based web service structure.

  • C#: Problem trying to resolve a class when two namespaces are similar

    - by rally25rs
    I'm running into an issue where I can't make a reference to a class in a different namespace. I have 2 classes: namespace Foo { public class Class1 { ... } } namespace My.App.Foo { public class Class2 { public void SomeMethod() { var x = new Foo.Class1; // compile error! } } } The compile error is: The type or namespace name 'Class1' does not exist in the namespace 'My.App.Foo' In this situation, I can't seem to get Visual Studio to recognize that "Foo.Class1" refers to the first class. If I mouse-over "Foo", it shows that its trying to resolve that to "My.App.Foo.Class1" If I put the line: using Foo; at the top of the .cs file that contains Class2, then it also resolves that to "My.App.Foo". Is there some trick to referencing the right "Foo" namespace without just renaming the namespaces so they don't conflict? Both of these namespaces are in the same assembly.

  • How to configure AutoMapper if not ASP.net Application?

    - by alex
    I'm using AutoMapper in a number of projects within my solution. These projects may be deployed independantly, across multiple servers. In the documentation for AutoMapper it says: If you're using the static Mapper method, configuration only needs to happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global.asax file for ASP.NET applications. Whilst some of the projects will be ASP.net - most of these are class libraries / windows services. Where should I be configuring my mappings in this case?

  • Cant open Nerd Dinner 1.0 VS 2008 SP1 MVC 2

    - by josephj1989
    I was trying to download some ASP.NET MVC Sample application to learn MVC. I tried Music Store and TownHall but they wont open in my VS2008.So I tried the common Nerddinner 1.0 but it gives error "The project Type is not supported by this installation" . I tried the 3rd Method suggested in the following post http://stackoverflow.com/questions/1002907/cant-open-nerddinner-project-in-vs2008 This is about changing the project type GUIDS.Now the project loads but when I run it throws an exception <add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> I presume this is happening because the Nerddinner 1.0 is for MVC 1.0 and I have MVC 2.0 installed. How do I proceed now. I have spent a lot of time trying to get an MVC application working on my PC. I am happy if I can get any properly architected , MVC application of medium to high complexity to work on my PC. thanks

  • Can jQuery animate() behave differently for specific elements within my selection?

    - by Sune Rasmussen
    I have a selection of elements in a jQuery object. I want to animate their font sizes, but as I have both the headlines and various paragraphs in the selection, they should be animated slightly differently, as the headlines should end up with a larger font size than the paragraphs. I already have this information stored in the jQuery data cache. I can do that. But, not unless I use several calls to the animate function, one for each specific, slightly different animation, perhaps using event triggering or setTimeout() calls. Of course I want to avoid this, as it's damn ugly and an odd way around. Much prettier if it could be done internally, within the animation ... Any help would be much appreciated.

  • Running NUnit Tests from Code

    I'm trying to write a simple method that receives a file an runs it using NUnit.

What am I missing?

  • Best way to get an Application Context into a static method in Android

    - by Slapout
    I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

  • Is there a better way than #if DebugMode for logging

    - by Daniel
    I'm making a c++ library thats going to be P/Invoked from c#, so i am unable to breakpoint/debug the c++ side of things. So i decided to add logging so i can see if anything goes wrong and where it happens. I add a #define DebugMode 1 in order to determine if i am to log or not. First of all i'm not very good at c++ but i know enough to get around. So my questions are: Is there a better way than wrapping #if DebugMode #endifs around every Log call? I could simply do that inside the method and just return if logging isn't disabled but won't that mean then all those logging strings will be in the assembly? How can i emulate what printf does with its "..." operator enabling me to pass something like Log("Variable x is {0}", x); Thanks!

  • jQuery internals: Organization of the jQuery Object

    - by sonofdelphi
    I was going through the source code of jQuery. I'm having trouble understanding the wrapping strategy for the jQuery object. (function( window, undefined ) { // Define a local copy of jQuery var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); }, .... .... .... // Expose jQuery to the global object window.jQuery = window.$ = jQuery; })(window); Specifically, what I'm not able to understand stems from the first line. What is the outermost unnamed container function? Why is it required? Why is the container function anonymous? What is the need for the outermost '(' parantheses ?

  • How should I implement items that are normalized in the Database, in Object Oriented Design?

    - by Jonas
    How should I implement items that are normalized in the Database, in Object Oriented classes? In the database I have a big table of items and a smaller of groups. Each item belong to one group. This is how my database design look like: +----------------------------------------+ | Inventory | +----+------+-------+----------+---------+ | Id | Name | Price | Quantity | GroupId | +----+------+-------+----------+---------+ | 43 | Box | 34.00 | 456 | 4 | | 56 | Ball | 56.50 | 3 | 6 | | 66 | Tin | 23.00 | 14 | 4 | +----+------+-------+----------+---------+ Totally 3000 lines +----------------------+ | Groups | +---------+------+-----+ | GroupId | Name | VAT | +---------+------+-----+ | 4 | Mini | 0.2 | | 6 | Big | 0.3 | +---------+------+-----+ Totally 10 lines I will use the OOP classes in a GUI, where the user can edit Items and Groups in the inventory. It should also be easy to do calculations with a bunch of items. The group information like VAT are needed for the calculations. I will write an Item class, but do I need a Group class? and if I need it, should I keep them in a global location or how do I access it when I need it for Item-calculations? Is there any design pattern for this case?

  • How can I access data that's stored in my App Delegate from my various view controllers?

    - by BeachRunnerJoe
    This question is similar to this other post, but I'm new to iPhone development and I'm getting used to the good practices for organizing my data throughout my app. I understand the ApplicationDelegate object to be the best place to manage data that is global to my app, correct? If so, how can I access data that's stored in my App Delegate from various view controllers? Specifically, I have an array of table section titles for my root table view controller created as such... appdelegate.m sectionTitles = [[NSArray alloc] initWithObjects: @"Title1", @"Title2", @"Title3", nil]; rootViewController.appDelegate = self; and I need to access it throughout the different views of my app, like such... rootviewcontroller.m NSUInteger numSections = [self.appDelegate.sectionTitles count]; Is this the best way to do it or are there any reasons I should organize my data a better way? Thanks so much in advance for your help!

  • Are indivisible operations still indivisible on multiprocessor and multicore systems?

    - by Steve314
    As per the title, plus what are the limitations and gotchas. For example, on x86 processors, alignment for most data types is optional - an optimisation rather than a requirement. That means that a pointer may be stored at an unaligned address, which in turn means that pointer might be split over a cache page boundary. Obviously this could be done if you work hard enough on any processor (picking out particular bytes etc), but not in a way where you'd still expect the write operation to be indivisible. I seriously doubt that a multicore processor can ensure that other cores can guarantee a consistent all-before or all-after view of a written pointer in this unaligned-write-crossing-a-page-boundary situation. Am I right? And are there any similar gotchas I haven't thought of?
