  • Running a loop (such as one for a mock webserver) within a thread

    - by bob c
    I'm trying to run a mock webserver within a thread within a class. I've tried passing the class' @server property to the thread block but as soon as I try to do server.accept the thread stops. Is there some way to make this work? I want to basically be able to run a webserver off of this script while still taking user input via stdin.gets. Is this possible? class Server def initialize() @server = TCPServer.new(8080) end def run() @thread = Thread.new(@server) { |server| while true newsock = server.accept puts "some stuff after accept!" next if !newsock # some other stuff end } end end def processCommand() # some user commands here end test = Server.new while true do processCommand(STDIN.gets) end In the above sample, the thread dies on server.accept

  • how can i introspect properties and model fields in django?

    - by shreddd
    I am trying to get a list of all existing model fields and properties for a given object. Is there a clean way to instrospect an object so that I can get a dict of fields and properties. class MyModel(Model) url = models.TextField() def _get_location(self): return "%s/jobs/%d"%(url, self.id) location = property(_get_location) What I want is something that returns a dict that looks like this: { 'id' : 1, 'url':'http://foo', 'location' : 'http://foo/jobs/1' } I can use model._meta.fields to get the model fields, but this doesn't give me things that are properties but not real DB fields.

    I have a .swf which loads an external .swf: this.createEmptyMovieClip("container_mc", this.getNextHighestDepth()); var my_listener:Object = new Object(); my_listener.onLoadComplete = function(target_mc:MovieClip) { target_mc._x = 50; target_mc._y = 50; addChild(my_loader); var blocker = my_loader.content.test blocker._visible = false; } my_listener.onLoadProgress = function(target_mc:MovieClip) { trace(target_mc.getBytesLoaded() + " out of " + target_mc.getBytesTotal()); } var my_loader:MovieClipLoader = new MovieClipLoader(); my_loader.addListener(my_listener); my_loader.loadClip("child_as2.swf", container_mc); I want to acces the external swf and make the movieclip with instance name test visible = false; but it won't work.

  • Why is the page shifting to top with a container that has overflow:hidden ?

    - by Maher4Ever
    I'm facing a problem that's really strange. It's in every browser. Everything is working correctly, until you try to go to a section using the hash ( like #contactUs in my page)... try this url : http://mahersalam.co.cc/projects/2011/#contactUs You will see that the page SHIFTS 10px to the top. if you take the hash, it works again. I have a wrapper on the page (#container) that has overflow:hidden, I did it to make sure no scroll bars appear if the resolution change. If you remove the overflow property it works too. I guess the shifting happens through the place of the scroll bar, but because it's hidden it's place only stays. So does anyone knows how to fix this problem ?

  • Silverlight 4 Binding to ConverterParameter

    - by FrEEzE2046
    Hello everybody, I have a ValueConverter which needs to be called with a dynamic parameter, depending on a property. I can't see a way to do this ... Width="{Binding ActualWidthValue, Source={StaticResource VisibleSize}, Converter={StaticResource Fraction}}" The "Fraction" converter get's (or should get) a parameter of type System.Size, which contains a numerator and denumerator. This value (should) depend on a ItemCollection.Count. Resetting the ItemCollection should reinvoke the Converter with the new values. My first idea was to manually change the ConverterParameter in CodeBehind on the PropertyChanged event of my ItemCollection DependencyProperty. But, as I know now, Silverlight has no GetBinding() method. I heard about GetBindingExpression and tried to do. But MyGrid.GetBindingExpression(Grid.ActualHeightProperty) is always returning null, although the Binding is already established. So, what can I do to reach my target?

  • Is possible to remove an event listener in actionscript 3 (flash) ??

    - by DomingoSL
    In the frame 1 of my movie, part of my code is: stage.addEventListener(Event.RESIZE, resizeHandler); It works all fine, but when i go to the frame 2 the listener is still there but the function resizeHandler is not anymore (and i dont want it). So the console output this: TypeError: Error #1009: Cannot access a property or method of a null object reference. at index_fla::MainTimeline/resizeHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at flash.display::Stage/dispatchEvent() at index_fla::MainTimeline/frame2() Is possible to remove the event listener on the frame 2? Thanks!!!

  • Using a .delay() function before .css() manipulation in jQuery

    - by Fabian
    I have this: var $ul = $(this).children("ul"); $ul.animate({opacity: 0}, 1000); $ul.delay(1000).css("display", "none") It's for my dropdown menu, and I want it to fade off before it disappears using the display: none; CSS property. However it appears that the .delay() cannot be used on the .css(); it doesn't work, the $ul just disappears right away. I can't use $ul.animate({opacity: 0, display: "none"}, 1000); either.

  • If I can't use datacontext in a static

    - by Richard77
    Hello, I've got this public static class MyClassHelper { DataContex db = new DataContext(); public static Type MyMethod() { //Do Something with db // such as db.myTable } } I'm getting the following error: "An object reference is required for the non-static field, method or property..." Is there anyway to get around this? How about this. I've an object that contains only integers, which is fine for all the internal functionings as it allows me to link tables. But occasionaly, I need to display some information to the user. That's why, I'd like to create a static method so it would read the integer, look up in the DB, and display a name instead of a number. I want it to be a static method so that I can use it in my View template. Thanks for helping

  • How can i do something like IList<T>.Contains(OtherObjectType) ?

    - by Noctris
    Hi, I have the following classes: Client ClientCacheMedia ( contains Client, Media and some other parameters so it is the link between the media and the client) Media where client contains an IList. Now what i would like to do, is have a way to check if this ilist contains a certain media so : Client.ClientCacheMedia.Contains(MyMedia) is there any way to let the IList accept media as an object to match ? ( i can easily override the Equals Property on ClientCacheMedia to check if the media passed is the one that the ClientCacheMedia.Media contains, it's just the Ilist that will not accept any other object on the Contains Method.

  • Full background using :cover; makes adds horizontal scroll

    - by user1907341
    I am working on a website which needs a header with full background image & 650 height. At the moment i am using background-size: cover; property with 100% width. While, it's working it leaves an awkward horizontal scroll of about 50px on right side. Which is lot more prominent in smaller resolutions. I tried applying background to body instead of header div too. But same thing happens there as well. You can see a preview here - http://nitingarg.com/projects/tfe/

  • WPF - hiding listbox items

    - by user553765
    Hi, I have a listbox where the itemtemplate is using a style. The styles specifies a border with a datatrigger setting the visibility of the border to collapsed depending on a property. This works fine except I can still see a very narrow line for each item, in the list, that is collapsed. I was hoping someone could help with how to set the visibility so that there are no visible traces as this is quite apparent when consecutive items have been collapsed. The datatemplate specifies an outer border with a dockpanel inside of this - there are then stackpanels docked to this. Any help is appreciated.

  • Forking with a listening socket

    - by viraptor
    I'd like to make sure about the correctness of the way I try to use accept() on a socket. I know that in Linux it's safe to listen() on a socket, fork() N children and then recv() the packets in all of them without any synchronisation from the user side (the packets get more or less load-balanced between the children). But that's UDP. Does the same property hold for TCP and listen(), fork(), accept()? Can I just assume that it's ok to accept on a shared socket created by the parent, even when other children do the same? Is POSIX, BSD sockets or any other standard defining it somewhere?

  • Change macro in VisualStudio

    - by Vaccano
    The macro 'propdp' creates a dependency property like this: public int MyProperty { get { return (int)GetValue(MyPropertyProperty); } set { SetValue(MyPropertyProperty, value); } } // Using a DependencyProperty as the backing store for MyProperty. This enables animation, styling, binding, etc... public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register("MyProperty", typeof(int), typeof(ownerclass), new UIPropertyMetadata(0)); I would like to change it a bit. To look like this: public int MyProperty { get { return (int)GetValue(MyPropertyProperty); } set { SetValue(MyPropertyProperty, value); } } public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register("MyProperty", typeof(int), typeof(ownerclass), new UIPropertyMetadata(0)); Can this be done? Does anyone know where to change this?

  • Why does `Array.length`, `Function.length`, `String.length`, etc return 1?

    - by zealoushacker
    While teaching my JavaScript class yesterday, my students and I came across some interesting functionality that I thought might be worth capturing in a question and the answer I've come to. Typing Array.length in the JS console in chrome returns 1. Likewise, Function.length returns 1. This is important because: Every function in JavaScript is actually a Function object. (MDN JS Ref: Function) Thus, Object.length and likely all other native objects will and should return 1 as the value of the length property. So, finally why is this behavior occurring?

  • What size should the background image in an MSI be?

    - by r_
    I am trying to create a Windows Installer package using Wix. I'm getting a lot of conflicting information about what size my custom background should be--the Wix documentation suggests a size of 500 x 314 pixels, but this leads to slight image distortion in the installer. I believe that I may be indirectly using the SplashBitmap property in Windows Installer, whose documentation suggests 480 x 320 is the correct size. When I try to use this image size, I also get artefacts in the image. Could anyone tell me what the correct size should be?

  • Delphi: what are the 8 mystery components on my form?

    - by mawg
    When I iterate of the controls on my form, I see those which I placed there at design time or run time. They are all of type TEdit, Tmemo, TComboBox, etc ... However, there are always exactly eight which I do not recognize. I can skip over them, since they are not of a type which interests me, but I am curios. I am guessing system controls like min/max/close. Their Name property is empty. Is there any way I can determine what type they are (without explicitly testing for every standard component derived from TWinControl) ? I am curious - but not yellow ;-)

  • Use of .apply() with 'new' operator. Is this possible?

    - by Premasagar
    In JavaScript, I want to create an object instance (via the new operator), but pass an arbitrary number of arguments to the constructor. Is this possible? What I want to do is something like this (but the code below does not work): function Something(){ // init stuff } function createSomething(){ return new Something.apply(null, arguments); } var s = createSomething(a,b,c); // 's' is an instance of Something The Answer From the responses here, it became clear that there's no in-built way to call .apply() with the new operator. However, people suggested a number of really interesting solutions to the problem. My preferred solution was this one from Matthew Crumley (I've modified it to pass the arguments property): var createSomething = (function() { function F(args) { return Something.apply(this, args); } F.prototype = Something.prototype; return function() { return new F(arguments); } })();

  • Setting language/culture for reporting services report rendered through C#

    - by Chris Latta
    I have written a report renderer in C# that runs and attaches reports to an email. This is all working great, except the date format of the parameters are incorrect when listed in the report title. All the reports have their language set to =User!Language and the parameters are output using the FormatDateTime function to format according to the user's regional settings. I am basically using the rendering method described here on MSDN. This all works great when the reports are run through the browser. However, when I render the report from C# it uses en-US date format. The report server's regional settings are set appropriately to the correct region as are the regional settings of the computer the C# progam is running on.. What property do I need to set in my C# program for the report to be rendered using my appropriate language/culture?
