  • ASP webservice serialization of properties

    - by badra
    I got a class like this which gets returned from an ASP webservice: class Data { public int A { get; set; } public int B { get; set; } public int Sum { get { return A + B; } } } When I try to consume the webservice on the client side using Silverlight I only get the properties A and B but I also need Sum. I know I can't return any logic from a webservice, so the expected behavior was it will return the the Sum as a fixed/precalculated property in the client which is what I need. Any ideas except for redesigning my class? Thanks ...

  • Changing the cursor in WPF sometimes works, sometimes doesn't

    - by Scott
    On several of my usercontrols, I change the cursor by using this.Cursor = Cursors.Wait; when I click on something. Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to do with the fact that it's a button, or because this is a page and not a usercontrol? This seems like weird behavior.

  • Importing CSV with line breaks in Excel 2007

    - by ph0enix
    I'm working on a feature to export search results to a CSV file to be opened in Excel. One of the fields is a free-text field, which may contain line breaks, commas, quotations, etc. In order to counteract this, I have wrapped the field in double quotes ("). However, when I import the data into Excel 2007, set the appropriate delimiter, and set the text qualifier to double quote, the line breaks are still creating new records at the line breaks, where I would expect to see the entire text field in a single cell. I've also tried replacing CR/LF (\r\n) with just CR (\r), and again with just LF (\n), but no luck. Has anyone else encountered this behavior, and if so, how did you fix it? TIA, -J

  • UserControl that is also a Grid in WPF

    - by drasto
    I would like to create a UserControl that will have some behavior(animated collapsing...) and some Controls in it (Rectangle, Ellipse, mostly for design purposes). However I need it to be a valid Panel like Grid so I can put more controls in it when designing main window. Controls that will be add to the new USerControl in main window design time does not need to interact with components that are added to it when creating a UserControl. How should I do this ? Do I have to extends Control? I'd prefer to extend just UserControl.

  • How to simulate :active css pseudo class in android on non-link elements?

    - by chas s.
    I'd like to be able to mimic the behavior of the :active pseudo class on all elements in Android webkit. Currently, the :active syntax only works on a elements (links). Nearly all of the actionable elements in the app I'm working on are something other than a standard link tag. iOS webkit supports :active on all elements. /* works on both android iOS webkit */ a:active { color: blue; } /* works on iOS webkit, does not work on android webkit */ div:active { color: red; } I've found a couple of resources [1,2] that solve similar problems, but they're both a bit heavy, and I'm wondering if there's a lighter weight solution that I'm just not able to find. http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone http://code.google.com/intl/ro-RO/mobile/articles/fast_buttons.html

  • What is the difference between Invoking and BeginInvoking a MessageBox?

    - by mafutrct
    In a form, compare BeginInvoke (new Action (() => { MessageBox.Show ()); })); with Invoke (new Action (() => { MessageBox.Show ()); })); What is the difference, and when should I use one over the other? How is the behavior affected by the message pump of the MessageBox? I did some testing and found that both methods block the UI. The only difference is that Invoke is actually called instantly while BeginInvoke takes a (very short) time until the code is run. This is to be expected.

  • How to avoid "incomplete implementation" warning in partial base class

    - by garph0
    I have created a protocol that my classes need to implement, and then factored out some common functionality into a base class, so I did this: @protocol MyProtocol - (void) foo; - (void) bar; @end @interface Base <MyProtocol> @end @interface Derived_1 : Base @end @interface Derived_2 : Base @end @implementation Base - (void) foo{ //something foo } @end @implementation Derived_1 - (void) bar{ //something bar 1 } @end @implementation Derived_2 - (void) bar{ //something bar 2 } @end In this way in my code I use a generic id<MyProtocol>. The code works (as long as Base is not used directly) but the compiler chokes at the end of the implementation of Base with a warning: Incomplete implementation of class Base Is there a way to avoid this warning or, even better, a more proper way to obtain this partially implemented abstract base class behavior in Objc?

  • Redirect to prevent dup submission...but then you loose existing data

    - by coffeeaddict
    Here's the scenario User is on your checkout.aspx page Somewhere in the process, when clicking the pay button, you redirect the user to an intermediate page (before the confirmation page) to do some other logic. That intermediate page performs whatever logic based on a querystring flag you sent with the redirect from the checkout page This intermediate page also serves as an error page. So if any logic in the intermediatePage.aspx.cs fails I'm setting a message to be displayed on this page to the user If I refresh, that querystring value is still in the url..hence when it hits my Page_Load again, then the server-side logic is called & run again and I don't want this to happen The avoid this behavior/problem, the logical next step is to do a redirect back to the same page if they refresh (not sure how you'd catch that) to get rid of that querystring But when you redirect back to the same page your error message is gone, lost in the redirect therefore you end up showing them the same page but all values for the error message are now gone I do not want to solve this with Javascript either. I am not sure the best way to handle this.

  • misleading plot issue in mathematica

    - by Qiang Li
    I want to study some "strange" functions by plotting them out in mathematica. One example is the following: mod2[x_] := Which[Mod[x, 2] >= 1, -2 + Mod[x, 2], True, Mod[x, 2]]; f[x_] := Which[-1 <= x <= 1, Abs[x], True, Abs[mod2[x]]]; fn[x_, n_] := Sum[(3/4)^i*f[4^n*x], {i, 0, n}] Plot[{fn[x, 0], fn[x, 1], fn[x, 2], fn[x, 5]}, {x, -2, 2}] However, the plot I got from mma is misleading, in the sense that the maxima and minima of fn[x, 5] should be on the same two levels. But due to high oscillation of the function, and the fact that clearly mma only takes limited number of points to draw the function, you see the plot exhibit strange behavior. Is there any option in plot to remedy for this? Many thanks.

  • Constant Assigment Bug in Ruby?

    - by aronchick
    We caught some code in Ruby that seems odd, and I was wondering if someone could explain it: $ irb irb(main):001:0> APPLE = 'aaa' => "aaa" irb(main):002:0> banana = APPLE => "aaa" irb(main):003:0> banana << 'bbb' => "aaabbb" irb(main):004:0> banana => "aaabbb" irb(main):005:0> APPLE => "aaabbb" Catch that? The constant was appended to at the same time the local variable was. Known behavior? Expected?

  • MVC Html.DropDownList closes prematurely in IE7

    - by Jon
    I'm using ASP.NET MVC with jquery. I have a couple of dropdownlists. When I select one via mouse click and then scroll down over the items using the mouse/cursor, the list closes before a selection can be made, before the mouse can be clicked. This doesn't happen when I open them and then up/down arrow to select an item. It doesn't happen all of the time, but a lot. Just to try something different, I added a jquery "select" control with hardcoded values (options) and it displays the same behavior. Any ideas? <%: Html.DropDownList("Accounts", (IEnumerable)ViewData["Accounts"], "-- Select an account --")% Thank you

  • super(type,subclass) in simple singleton implementation

    - by Tianchen Wu
    when I was implementing naive singleton in python, I came up with a problem with super key word. As usual the behavior of super is always tricky and buggy, hope someone can shed light on it. Thanks :) The problem is that: class Singleton(object): def __new__(cls,*args,**kw): if not hasattr(cls,'_instance'): #create a instance of type cls, origin=super(Singleton,Singleton).__new__(cls,*args,**kw) cls._instance=origin return cls._instance class B(Singleton): def __init__(self,b): self.b=b It actually works, but I am wondering Will it be better if I change line 5 to the below, like in most of the books? origin=super(Singleton,cls).__new__(cls,*args,**ks) what's the difference to make?

  • Using jQuery.get with a file up a directory?

    - by gct
    I'm using jQuery to write a simple utility app that's just run locally. It'll read from a list of files using jQuery.get and then display them along with some meta-data (which resides in a separate file). The images and meta files live in ../scored_images/*.[jpg|meta] I can load the file list with jQuery.get just fine (it's in the current directory), and I can load up the images and display them without a problem. However when I go to load the meta file for display, jQuery.get seems to silently fail. I can load them fine if the path doesn't have ../ in it. Is there a way to work around this behavior?

  • jQuery Week Calendar overlapping problem

    - by araid
    Hi, I'm developing an application with uses this calendar for resource reservation, but I have a problem when creating a new event. I don't want events to overlap, so I set allow allowCalEventOverlap to false. However, it still overlaps in a transparent way. But the biggest problem is that I can't drag an event if there's another on the same day, even if their start and end dates don't overlap. You can try this strange behavior in the 2nd demo: http://robmonie.github.com/jquery-week-calendar/weekcalendar_demo_2.html Any help on how to fix or understand it will be very appreciated. Regards,

  • Mac OS X 10.5 App "not supported on this architecture" cured by copying?

    - by JWWalker
    I have an app that updates itself over the internet, and the updated copy won't run on PowerPC machines (G5) running Leopard (10.5.8). Double-clicking the app produces a message saying "You can't open the application "appname" because it is not supported on this architecture." But here's the weird part: if I duplicate the app using the Finder or using a cp -R command, then the duplicate runs fine! And yet, if I do ls -laeR on both apps, the results are identical. I restarted the machine, and the difference between the two copies was still there. Sometimes, renaming the app made it run. After a few tries, I managed to rename it back to the original name and still have it run. If this was just on one machine, I'd dismiss it as disk corruption, cosmic rays, or a voodoo hex, but it was reported by a customer and then I reproduced it on my own machine. Any ideas what could cause this behavior?

  • compiling boost based application using cron

    - by user303544
    Hi All, I am building some boost based application for various embedded targets. I have developed a script which can build my application with different toolchain for several targets. This script works fine when I run it from command line but if it is invoked from cron it always fails to link the object files. My application has dependency on openssl. Can anyone please give some idea? What would be the root cause of this kind of behavior? Thanks in advance.

  • System.NullReferenceException with WhoCanHelpMe Unit Test

    - by tlum
    I'm working with a test project based on WhoCanHelpMe, which is based on Sharp Architecture, NHibernateValidator, etc. As its written the when_the_profile_tasks_is_asked_to_create_a_profile unit test creates the profile object and saves it without issue. Now the profile object is a CreateProfileDetails type that derives from their own ValidatableValueObject which inherits the IValidatable interface. The problem surfaces when my class is based on an Entity rather than their ValidatableValueObject. When the test is run a System.NullReferenceException because Validate() is null. I'm afraid that I'm at a loss to resolve this bad behavior. Does anyone have some suggestions to get to the bottom of this? Thanks, -Ted-

  • How can I use foreach and fork together to do something in parallel?

    - by kaushalmodi
    This question is not UVM specific but the example that I am working on is UVM related. I have an array of agents in my UVM environment and I would like to launch a sequence on all of them in parallel. If I do the below: foreach (env.agt[i]) begin seq.start(env.agt[i].sqr); end , the sequence seq first executes on env.agt[0].sqr. Once that gets over, it then executes on env.agt[1].sqr and so on. I want to implement a foreach-fork statement so that seq is executed in parallel on all agt[i] sequencers. No matter how I order the fork-join and foreach, I am not able to achieve that. Can you please help me get that parallel sequence launching behavior? Thanks.

  • How save JavaScript and HTML in option without it being auto-escaped?

    - by bobsoap
    And there I thought I knew Wordpress well. It now seems that update_option() auto-escapes code. If I want to save some Javascript or HTML code in an option, this behavior renders the code unusable. I refuse to do a str_replace on the returned value to filter out every backslash. There has to be a better way. Here's the PHP for the text box to enter some code: $option = unserialize(get_option('option')); <textarea name="option[box]"><?php echo $option['box']; ?></textarea> This is what happens after submitting the form (in essence): update_option('option', serialize($_POST)); Any ideas?

  • Samsung TV Emulator font size

    - by jperovic
    Can someone please help me with this issue. I've been banging my head to find the solution but no help... The problem is that Samsung TV Emulator displays everything enlarged (line font-size 30ish pixels) and there does seem to have a way to override it. This only happens within Samsung UI components. To make sure it wasn't something with my project I've downloaded sample project from Brightcove: Sample project but noticed the same behavior with that as well. Here is the screenshot of my "project". It only one scene with two UI components: http://tinypic.com/r/124evqc/6 Opposed to that, here's what I see in my IDE view: http://tinypic.com/r/ezmn4l/6. As a side-note, I had to put height: 20px in both of my UI components' CSS in order for IDE to show them that way. Can anyone suggest what am I supposed to do?

  • Can a webflow's action state have multiple redirects on success?

    - by callie16
    Say, I have this type of webflow: def myFlow = { state1 { } on("next").to("stateAct") stateAct { action { ... DB stuff ... } } on("success").to("state2") state2 { } on("prev").to("state1") } Now, the contents of "stateAct" is common between state1 and state2. Meaning, if I press "next" from state1, I need to pass by stateAct before I can go to state2 (which is the current implementation) and if I press "prev" in state2, I need it to pass by stateAct before it goes to state1. Obviously, in the sample webflow above, it doesn't do the latter. So, my question is, is there a way to detect in stateAct who called it (state1 or state2) so that I can redirect accordingly on "success"? Or something similar to that behavior? Thanks! -Lee

  • Med-PC Programing Language

    - by mknuii
    There's this programing language called Med-PC that works with animal behavior. I'm trying to learn a bit about it, but i can't seem to find any kind of books or material about it. I've "google it" but all i seem to find are some references about it and a PDF explaining the installing of the program itself and sensors(for the experiments), not actual programing instructions. I'm looking for some kind of guidance, documents or books, some kind of reference where i can improve and learn about this language, or if it is based on some other language. I just need some reference about it. So i've resorted to StackOverFlow to see if anybody has worked, knows about it or can point me some links/books about it.

  • Debug.writeline locks

    - by Carra
    My program frequently stops with a deadlock. When I do a break-all and look at the threads I see that three threads are stuck in our logging function: public class Logging { public static void WriteClientLog(LogLevel logLevel, string message) { #if DEBUG System.Diagnostics.Debug.WriteLine(String.Format("{0} {1}", DateTime.Now.ToString("HH:mm:ss"), message)); //LOCK #endif //...Log4net logging } } If I let the program continue the threads are still stuck on that line. I can't see where this can lock. The debug class, string class & datetime class seem to be thread safe. The error goes away when I remove the "#if DEBUG System... #endif" code but I'm curious why this behavior happens. Thread one: public void CleanCache() { Logging.WriteClientLog(LogLevel.Debug, "Start clean cache.");//Stuck } Thread two: private void AliveThread() { Logging.WriteClientLog(LogLevel.Debug, "Check connection");//Stuck }
