  • How to create a separate thread to do some operation periodically and update UI in WPF?I'm stack

    - by black sensei
    Hello Experts! I'm trying to do a periodic separated thread operation let's say check for internet connection or check for user's info via web service and update the user interface. i've tried with quartz.net to implement that.So i created an inner class for the window i need to update.That inner class does what is meant for but the problem is that i don't know how to access parent's(window class) members form the child(inner class). for example public partial class Window2 : Window { private int i; public Window2() { InitializeComponent(); } public string doMyOperation() { //code here return result; } public class Myclass :IJob { public void Execute(JobExecutionContext context) { string result = doMyOperation(); //Now here i could be able to call a label of name lblNotif //lblNotif.Content = result; } } } Well the whole idea works but i'm stacked at here i need to access a controls of Window2 Since i'm stacked i tried Spring.Net way of implementing Quartz hoping that i could use MethodInvokingJobDetailFactoryObject and rather have the Operation done on Window2 itself.But for some reason i'm having an exception Cannot resolve type [System.Windows.Window2,System.Windows];, could not load type from string value System.Windows.Window2,System.Windows and the wiring is done so <object name="UpdateLabelJob" type="System.Windows.Window2,System.Windows"/> What i'm i doing wrong here?Is that a way round? thanks for reading and for helping out

    - by MrTemp

  • RIA Service - without database?

    - by Heko
    Helo! I need to write a RIA service to call Java webservices from Silverlight 3.0 app. I'm testing how stuff works and in my Web app I have a MyData class which has 2 properties (int ID, string Text): namespace SilverlightApplication1.Web { public class MyData { [Key] public int ID { get; set; } public string Text { get; set; } } } Then I wrote simple DomainService: [EnableClientAccess()] public class MyService : DomainService { public IQueryable<MyData> GetMyData(string Url) { // here I will call my WebService List<MyData> result = new List<MyData>(); result.Add(new MyData { ID = 1, Text = Url }); return result.AsQueryable(); } } } How can I get data into my SL app? Now I have this: namespace SilverlightApplication1 { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MyContext context = new MyContext(); } } } I called and load but nothink worsk (exceptions, or nulls)... I had Invoke annotation but MyData is not TEntity and I can't use Strings or other simple types as well... :/ I'm reading and reading posts and nothing works like it should.. Any help would be really appreciated. Thank you!

  • jQuery script works in Firefox but not in IE. Why am I not surprised?

    - by Ben Tew
    I'm working with the context of a CMS system and trying to turn seperate div's into tabs. You can see it at http://www.wtvynews4.com/test I've kludged together some code from a tutorial site. <script charset="utf-8" type="text/javascript"> jQuery(function() { //When page loads... $("div[ondblclick$='87119417']").attr("id", "87119417"); $("div[ondblclick$='87119482']").attr("id", "87119482"); $("div[ondblclick$='87119672']").attr("id", "87119672"); $("div[ondblclick$='87119727']").attr("id", "87119727"); $("div[ondblclick$='87119812']").attr("id", "87119812"); $("div[ondblclick$='87119417']").addClass("tab_content"); $("div[ondblclick$='87119482']").addClass("tab_content"); $("div[ondblclick$='87119672']").addClass("tab_content"); $("div[ondblclick$='87119727']").addClass("tab_content"); $("div[ondblclick$='87119812']").addClass("tab_content"); $(".tab_content").hide(); //Hide all content $("ul.morenewstabs li:first").addClass("active").show(); //Activate first tab $(".tab_content:first").show(); //Show first tab content //On Click Event $("ul.morenewstabs li").click(function() { $("ul.morenewstabs li").removeClass("active"); //Remove any "active" class $(this).addClass("active"); //Add "active" class to selected tab $(".tab_content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content $(activeTab).show(); //Fade in the active ID content return false; }); }); </script> Everything works fine in Firefox but not IE. can you provide any assistance? When the page loads the attribute ID's and classes aren't assigned. I tried changing jQuery(function() { to $(document).ready(function() still no luck.

  • Running a process at the Windows 7 Welcome Screen

    - by peelman
    So here's the scoop: I wrote a tiny C# app a while back that displays the hostname, ip address, imaged date, thaw status (we use DeepFreeze), current domain, and the current date/time, to display on the welcome screen of our Windows 7 lab machines. This was to replace our previous information block, which was set statically at startup and actually embedded text into the background, with something a little more dynamic and functional. The app uses a Timer to update the ip address, deepfreeze status, and clock every second, and it checks to see if a user has logged in and kills itself when it detects such a condition. If we just run it, via our startup script (set via group policy), it holds the script open and the machine never makes it to the login prompt. If we use something like the start or cmd commands to start it off under a separate shell/process, it runs until the startup script finishes, at which point Windows seems to clean up any and all child processes of the script. We're currently able to bypass that using psexec -s -d -i -x to fire it off, which lets it persist after the startup script is completed, but can be incredibly slow, adding anywhere between 5 seconds and over a minute to our startup time. We have experimented with using another C# app to start the process, via the Process class, using WMI Calls (Win32_Process and Win32_ProcessStartup) with various startup flags, etc, but all end with the same result of the script finishing and the info block process getting killed. I tinkered with rewriting the app as a service, but services were never designed to interact with the desktop, let alone the login window, and getting things operating in the right context never really seemed to work out. So for the question: Does anybody have a good way to accomplish this? Launch a task so that it would be independent of the startup script and run on top of the welcome screen?

  • Leftover Nav Bar in Landscape View

    - by Rob Bonner
    Hello, I am working to force a view into landscape mode, and have picked up all kinds of cool tips to make this happen, but am stuck on one item that is left on the screen. I have my XIB file laid out in landscape, and in my code I create the view controller normally: RedeemViewController *aViewController = [[RedeemViewController alloc] initWithNibName:@"RedeemViewController" bundle:nil]; aViewController.hidesBottomBarWhenPushed = YES; aViewController.wantsFullScreenLayout = YES; [[self navigationController] pushViewController:aViewController animated:YES]; Inside the controller viewDidLoad I complete the following: [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; [[self navigationController] setNavigationBarHidden:YES animated:YES]; [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:.75]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (self.interfaceOrientation == UIInterfaceOrientationPortrait) { self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90)); self.view.bounds = CGRectMake(0.0, 0.0, 480, 320); } [UIView commitAnimations]; What I end up with is a perfectly rotated view, with a grey vertical bar on the left side (see pic). So to the question, how do I get rid of the bar? Edit: I am pretty sure this is the navigation bar that is not being hidden. This is a duplicate of another post, with some modified code, the other question was being answered with the bug.

  • Prototype: Form.serialize missing some inputs (due to table?)

    - by Chris
    I'm using JavaScript Prototype (through Ruby on Rails) to handle some Ajax calls; but in one particular case I'm missing a field from the form. I have a layout like this: +---------+---------+ | Thing 1 | Thing 2 | +---------+---------+-----------+ | o Opt 1 | o Opt 1 | <Confirm> | | o Opt 2 | o Opt 2 | | +---------+---------+-----------+ Opt 1 and 2 are Radio buttons, Confirm is a button. The entire table is wrapped in a form, with code like: <form action="javascript:void(0)"> <input type="hidden" name="context" value="foo" /> <input type="hidden" name="subcontext" value="bar" /> <table> <tr><td>Thing 1</td><td>Thing2</td></tr> <tr><td> <input type="radio" name="choice" value="1.1" />Opt 1<br /> <input type="radio" name="choice" value="1.2" />Opt 2<br /> </td><td> <input type="radio" name="choice" value="2.1" />Opt 1<br /> <input type="radio" name="choice" value="2.2" />Opt 2<br /> </td><td> <input name="choice_btn" type="button" value="Confirm" onclick="new AJAX.Updater('my_form', '/process_form', {asynchronous:true, evalScripts:true, parameters:Form.serialize(this.form)}); return false;" /> </td></tr> </table> </form> But I can see that the POST generated by clicking the Confirm button contains the foo and bar values for the hidden fields, but not the choice of the radio buttons. Is this because I've got a table inside my form? How can I get around this?

  • Why my linux signal handler run only once

  • WCF publish/subscribe service, and ASP.NET MVC client

    - by d3j4vu
    I managed to develop a custom WCF service, using the publish / subscribe model, and hosted inside a managed windows service. Everything's working. I developed an interface as the service contract implementing a method definition marked as a non-one way operation contract (OperationContract(IsOneWay = false)]. This, to make possible returns an instance of a custom class derived from System.Web.Mvc.ActionResult. In the MVC app, event fires ok. It wraps inside an action method, (just the one defined in the interface), but, and this is my current problem, i believe that something relative to the execution context of the windows service (and the hosted wcf counterpart) blocks the execution of the action method in the MVC app. This is what i have until now (some pieces ripped off just to be more clear): /// Method definition for the contract's service. Maps to a MVC ActionMethod. [OperationContract(IsOneWay = false)] ActionResult Imagen(string data, CustomActionResult result); The class to hold an ActionResult derived class instance: public class ServiceEventArgsMvc : ServiceEventArgs { /// <summary> /// /// </summary> public CustomActionResult Result { get; set; } } And the code in the MVC client app: /// <summary> /// Just a simple class to hold an abstract ActionResult derived class instance. /// </summary> public ActionResult Image(string data, CustomActionResult result) { ViewData["data"] = data; return View(); } Ok. ActionMethod sucessfully executes...but when it's done (and usually expected obtain a reditection to a View named Image, like the action method), the WCF service throws a Timeout exception, making clear that he's still waiting for a response from the MVC client. The response never arrives, so the MVC app never finish his work (redirect to the "Image" view as expected). Any ideas?. Guess i'm missing something very simple, but i don't know what it could be. This is drivin' me nuts.

  • Android Facebook RequestListener

    - by Marcus King
    I'm new to Java, but have been a .NET developer for years now and I am a bit confused about the point of the RequestListener object as I can't retrieve the results of my asynchronous calls on the UI thread from what I can tell. My research has told me I should not use singletons or the application context object for getting and storing data. I could use sqlLite, but the data I need is too transient to bother. I would like to know how to have the asyncfacebookrunner object report back it's responses to the UI thread so I can proceed to make decisions between my own api and the objects returned to me from the facebook calls I am making in the async calls. Am I missing something? I can't seem to find a way to get data out. I can pass a Bundle in, but I'm not too sure how to get data out. I would think I would pass it an Intent object to retrieve, but I am not seeing it. I think my eyes are crossed from lack of sleep at this point. Any help here?

  • How do I cover unintuitive code blocks?

    For some reason, I'm having a hard time trying to cover the block of code below. This code is an excerpt from the UNIX uniq command.

  • C++: inheritance problem

    - by Helltone
    It's quite hard to explain what I'm trying to do, I'll try: Imagine a base class A which contains some variables, and a set of classes deriving from A which all implement some method bool test() that operates on the variables inherited from A. class A { protected: int somevar; // ... }; class B : public A { public: bool test() { return (somevar == 42); } }; class C : public A { public: bool test() { return (somevar > 23); } }; // ... more classes deriving from A Now I have an instance of class A and I have set the value of somevar. int main(int, char* []) { A a; a.somevar = 42; Now, I need some kind of container that allows me to iterate over the elements i of this container, calling i::test() in the context of a... that is: std::vector<...> vec; // push B and C into vec, this is pseudo-code vec.push_back(&B); vec.push_back(&C); bool ret = true; for(i = vec.begin(); i != vec.end(); ++i) { // call B::test(), C::test(), setting *this to a ret &= ( a .* (&(*i)::test) )(); } return ret; } How can I do this? I've tried two methods: forcing a cast from B::* to A::*, adapting a pointer to call a method of a type on an object of a different type (works, but seems to be bad); using std::bind + the solution above, ugly hack; changing the signature of bool test() so that it takes an argument of type const A& instead of inheriting from A, I don't really like this solution because somevar must be public.

  • Risky Business with LINQ to SQL and OR Designer?

    - by Toadmyster
    I have two tables with a one to many relationship in SQL 2008. The first table (BBD) PK | BBDataID | int       | Floor_Qty | tinyint       | Construct_Year | char(4)       | etc, etc describes the data common to all buildings and the second (BBDCerts) PK | BBDCertsID | int       | BBDataID | int       | Certification_Type | varchar(20)       | etc, etc is a collection of certifications for a particular building. Thus, the primary key in BBD (BBDataID) is mapped to the corresponding field in BBDCerts via an FK relationship, but BBDCertsID is the second table's primary key and BBDataID is not because it will not be unique. My problem is that I want to be able to use the OR generated data context to get at the list of certs when I access a particular record in the BBD table. For instance: Dim vals = (From q in db.BBD Where q.BBDataID = x Select q.Floor_Qty, q.Construct_Year, q.BBDCerts).SingleOrDefault and later be able to access a particular certification like this: vals.BBDCerts.Certification_Type.First Now, the automatic associations created when the SQL tables are dropped on the design surface don't generate the EntityRef associations that are needed to access the other table using the dot notation. So, I have to use the OR designer to make the BBDCerts BBDataID a primary key (this doesn't affect the actual database), and then manually change the association properties to the appropriate OneToMany settings. There might be a better way to approach this solution but my question is, is the way I've done it safe? I've done a barrage of tests and the correct cert is referenced or updated every time. Frankly, the whole thing makes me nervous.

  • LINQ to SQL - Lightweight O/RM?

    - by CoffeeAddict
    I've heard from some that LINQ to SQL is good for lightweight apps. But then I see LINQ to SQL being used for Stackoverflow, and a bunch of other .coms I know (from interviewing with them). Ok, so is this true? for an e-commerce site that's bringing in millions and you're typically only doing basic CRUDs most the time with the exception of an occasional stored proc for something more complex, is LINQ to SQL complete enough and performance-wise good enough or able to be tweaked enough to run happily on an e-commerce site? I've heard that you just need to tweak performance on the DB side when using LINQ to SQL for a better approach. So there are really 2 questions here: 1) Meaning/scope/definition of a "Lightweight" O/RM solution: What the heck does "lightweight" mean when people say LINQ to SQL is a "lightweight O/RM" and is that true??? If this is so lightweight then why do I see a bunch of huge .coms using it? Is it good enough to run major .coms (obviously it looks like it is) and what determines what the context of "lightweight" is...it's such a generic statement. 2) Performance: I'm working on my own .com and researching different O/RMs. I'm not really looking at the Entity Framework (yet), just want to figure out the LINQ to SQL basics here and determine if it will be efficient enough for me. The problem I think is you can't tweak or control the SQL it generates...

  • Javascript Namespace Help

    - by Jason
    Hi, I have a pretty big Javascript script with loads of global variables & functions in it. Then a piece of code that calls one function from this js file: myfunc(); Ok, now I have cloned this script and modified some functionality, all function prototypes and variables are named the same in both scripts. So now I have two scripts loaded and one call to myfunc(), now we have a clash because there are loads of global variables with the same names and two myfunc()s. What I want to do is wrap this cloned script in a namespace, so that I can modify the original call to: clone.myfunc() which will call the new function, but I also want myfunc() to just refer to the original script. In other words I can't touch the original script (no permissions) and I want to be able to use both the clone and the original at runtime. This is the script im cloning: http://pastebin.com/6KR5T3Ah Javascript namespaces seem quite tricky this seems a nice namespace method: var namespace = { foo: function() { } bar: function() { } } ... namespace.foo(); } However that requires using an object, and the script (as posted above) is humongous at nearly 4000 lines, too much to objectize I think? Anyone know a better solution to avoid namespace pollution, with one script I cant touch and one being a clone of that script. Just so I can call myfunc() and clone.myfunc() and all global variables will behave in their respected scope. It's either that, or I go through and modify everything to have unique names, which may take a lifetime This is a Mozilla addon if it helps context wise. Thanks.

  • Defining EditText imeOptions when using InputMethodManager.showSoftInput(View, int, ResultReceiver)

    - by TuomasR
    In my application I have a custom view which requires some text input. As the view in itself doesn't contain any actual views (it's a Surface with custom drawing being done), I have a FrameLayout which contains the custom view and underneath it an EditText -view. When the user does a specific action, the custom view is hidden and the EditText takes over for user input. This works fine, but android:imeOptions seem to be ignored for this view. I'm currently doing this: InputMethodManager inputMethodManager = (InputMethodManager)parent.getSystemService(Context.INPUT_METHOD_SERVICE); EditText t = (EditText)parent.findViewById(R.id.DummyEditor); t.setImeOptions(EditorInfo.IME_ACTION_DONE); inputMethodManager.showSoftInput(t, 0, new ResultReceiver(mHandler) { @Override protected void onReceiveResult( int resultCode, Bundle resultData) { // We're done System.out.println("Editing done : " + ((EditText)parent.findViewById(R.id.DummyEditor)).getText()); } } ); It seems that the setImeOptions(EditorInfo.IME_ACTION_DONE) has no effect. I've also tried adding the option to the layout XML with android:imeOptions="actionDone". No help. Any ideas?

  • What techniques do you use for emitting data from the server that will solely be used in client side scripts?

    - by chuck
    Hi all, I never found an optimal solution for this problem so I am hoping that some of you out there have a few solutions. Let's say I need to render out a list of checkboxes and each checkbox has a set of additional data that goes with it. This data will be used purely in the context of javascript and jquery. My usual strategy is to render this data in hidden fields that are grouped in the same container as the checkbox. My rendered HTML will look something like this: <div> <input type="checkbox" /> <input type="hidden" class="genreId" /> <input type="hidden" class="titleId" /> </div> My only problem with this is that the data in the hidden fields get posted to the server when the form is submitted. For small amounts of data, this is fine. However, I frequently work with large datasets and a large amount of data is needlessly transferred. UPDATE: Before submitting this post, I just saw that I can add a "DISABLED" attribute to my input element to suppress the submission of data. Is this pretty much the best approach that I can take? Thanks

  • Integration test for H1 text failing when it should be passing (Rspec and Capybara)

    - by rebec
    Below you can see my test for what happens when a user tries to access the page to edit a profile photo that they don't own. I've used the same test on the NEW action, where it worked fine, but it surprised me by failing when I copied it down to the EDIT action tests. I've used save_and_open_page to test what Capybara's seeing (as you can see below); the resulting page definitely has an h1 with the specified text in it. No spelling errors, and case is all the same as in the test. I've tried using both have_css and have_selector. Both fail. I'm still learning Ruby, Rails, Rspec and especially Capybara (was using webrat previously and recently switched over), and wonder if I'm misconceiving of something that's making me expect this to pass when it doesn't. Any thoughts? Thanks! describe "EDIT" do let(:user) { FactoryGirl.create(:user) } let(:different_user) { FactoryGirl.create(:user) } let(:admin_user) { FactoryGirl.create(:user, role: "admin") } let(:profile_photo1) { FactoryGirl.create(:profile_photo, user: user) } subject { page } context "when signed in as any member" do before { login different_user visit edit_user_profile_photo_path(:id => profile_photo1, :user_id => profile_photo1.user_id) save_and_open_page } # It should deny access with an Unauthorised/Forbidden message. it { should have_css('h1', text: "Unauthorised/Forbidden.") } end

  • 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?

  • ORDERBY "human" alphabetical order using SQL string manipulation

    - by supertrue
    I have a table of posts with titles that are in "human" alphabetical order but not in computer alphabetical order. These are in two flavors, numerical and alphabetical: Numerical: Figure 1.9, Figure 1.10, Figure 1.11... Alphabetical: Figure 1A ... Figure 1Z ... Figure 1AA If I orderby title, the result is that 1.10-1.19 come between 1.1 and 1.2, and 1AA-1AZ come between 1A and 1B. But this is not what I want; I want "human" alphabetical order, in which 1.10 comes after 1.9 and 1AA comes after 1Z. I am wondering if there's still a way in SQL to get the order that I want using string manipulation (or something else I haven't thought of). I am not an expert in SQL, so I don't know if this is possible, but if there were a way to do conditional replacement, then it seems I could impose the order I want by doing this: delete the period (which can be done with replace, right?) if the remaining figure number is more than three characters, add a 0 (zero) after the first character. This would seem to give me the outcome I want: 1.9 would become 109, which comes before 110; 1Z would become 10Z, which comes before 1AA. But can it be done in SQL? If so, what would the syntax be? Note that I don't want to modify the data itself—just to output the results of the query in the order described. This is in the context of a Wordpress installation, but I think the question is more suitably an SQL question because various things (such as pagination) depend on the ordering happening at the MySQL query stage, rather than in PHP.

  • OnClickListener on Tabs not working

    - by Aracos
    Greetings, I am trying to get the Click - event when clicking on the currently selected tab of my TabActivity. The onTabChangedHandler is only called whenever the tab is changed, not if the currently active Tab is clicked. The debugger tells me i have the onClickListener Registered for the TabWidget within my TabHost. Am i registering for the wrong View? Also, I am unable to create a Context Menu for the Tabs, only for its content, is this problem related? public class TestDroidViewTab extends TabActivity implements TabContentFactory , OnTabChangeListener, OnClickListener { private static final String LOG_KEY = "TEST"; ListView listView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final TabHost tabHost = getTabHost(); TabHost.TabSpec ts = tabHost.newTabSpec("ID_1"); ts.setIndicator("1"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_2"); ts.setIndicator("2"); ts.setContent(this); tabHost.addTab(ts); ts = tabHost.newTabSpec("ID_3"); ts.setIndicator("3"); ts.setContent(this); tabHost.addTab(ts); tabHost.setOnClickListener(this); tabHost.setOnTabChangedListener(this); } public void onClick(View v) { Log.d(LOG_KEY, "OnClick"); } public void onTabChanged(String tabId) { Log.d(LOG_KEY, "OnTabChanged"); }

  • NSManagedObject How To Reload

    - by crissag
    I have a view that consists of a table of existing objects and an Add button, which allows the user to create a new object. When the user presses Add, the object is created in the list view controller, so that the object will be part of that managed object context (via the NSEntityDescription insertNewObjectForEntityForName: method). The Add view has a property for the managed object. In the list view controller, I create an Add view controller, set the property to the managed object I created, and then push the Add view on to the navigation stack. In the Add view, I have two buttons for save and cancel. In the save, I save the managed object and pass the managed object back to the list view controller via a delegate method. If the user cancels, then I delete the object and pass nil back to the list view controller. The complication I am having in the add view is related to a UIImagePickerController. In the Add view, I have a button which allows the user to take a photo of the object (or use an existing photo from the photo library). However, the process of transferring to the UIImagePickerController and having the user use the camera, is resulting in a didReceiveMemoryWarning in the add view controller. Further, the view was unloaded, which also caused my NSManagedObject to get clobbered. My question is, how to you go about reloading the NSManagedObject in the case where it was released because of the low memory situation?

  • Externally disabling signals for a Linux program.

    - by Harry
    Hello, On Linux, is it possible to somehow disable signaling for programs externally... that is, without modifying their source code? Context: I'm calling a C (and also a Java) program from within a bash script on Linux. I don't want any interruptions for my bash script, and for the other programs that the script launches (as foreground processes). While I can use a... trap '' INT ... in my bash script to disable the Ctrl C signal, this works only when the program control happens to be in the bash code. That is, if I press Ctrl C while the C program is running, the C program gets interrupted and it exits! This C program is doing some critical operation because of which I don't want it be interrupted. I don't have access to the source code of this C program, so signal handling inside the C program is out of question. #!/bin/bash trap 'echo You pressed Ctrl C' INT # A C program to emulate a real-world, long-running program, # which I don't want to be interrupted, and for which I # don't have the source code! # # File: y.c # To build: gcc -o y y.c # # #include <stdio.h> # int main(int argc, char *argv[]) { # printf("Performing a critical operation...\n"); # for(;;); // Do nothing forever. # printf("Performing a critical operation... done.\n"); # } ./y Regards, /HS
