  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • Is it possible to manipulate the format on a DataGridView that is bound to a Data Source?

    - by Jack Johnstone
    I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the date format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d). I´ve created an algorithm for this transformation, but can I populate the affected cells with yyww,d instead of mm/dd/yyyy? And in that case - how would I do it? I guess I need to do it after the cells are populated, but before they are shown. The generic question is - how do I manipulate the format of Data Source bound DataGridView cells.

  • C++ private inheritance and static members/types

    - by WearyMonkey
    I am trying to stop a class from being able to convert its 'this' pointer into a pointer of one of its interfaces. I do this by using private inheritance via a middle proxy class. The problem is that I find private inheritance makes all public static members and types of the base class inaccessible to all classes under the inheriting class in the hierarchy. class Base { public: enum Enum { value }; }; class Middle : private Base { }; class Child : public Middle { public: void Method() { Base::Enum e = Base::value; // doesn't compile BAD! Base* base = this; // doesn't compile GOOD! } }; I've tried this in both VS2008 (the required version) and VS2010, neither work. Can anyone think of a workaround? Or a different approach to stopping the conversion? Also I am curios of the behavior, is it just a side effect of the compiler implementation, or is it by design? If by design, then why? I always thought of private inheritance to mean that nobody knows Middle inherits from Base. However, the exhibited behavior implies private inheritance means a lot more than that, in-fact Child has less access to Base than any namespace not in the class hierarchy!

  • Richfaces calendar manual input value not binding

    - by John
    Hi, I've got a richfaces calendar component defined as <rich:calendar id="startDate" value="#{myBean.dateSet.startDate}" timeZone="#{myBean.dateSet.timeZone}" datePattern="#{myBean.dateSet.datePattern}" enableManualInput="true" immediate="true"> <a4j:support event="onchanged" action="#{myBean.adjustEndDate}" reRender="startDate,endDate" ajaxSingle="true" /> </rich:calendar> when I'm changing the date using the calendar popup/gui everything is working fine. However when I'm changing it via the input text field, the value is not being updated to myBean.dateSet.startDate, although it is being updated correctly on the calendar component itself (i.e. if I click the icon for calendar popup it shows the updated current date). Any suggestions on how I can get it to update the value to myBean correctly? Thanks!

  • How would someone implement mathematical formulae in java?

    - by Mohit Deshpande
    What I mean is like have to user input a string with multiple variables and get the value of those variable. Like a simple quadratic formula: x^2 + 5x + 10. Or in java: (Math.pow(x,2)) + (x * 5) + 10The user would then enter that and then the program would solve for x. I will be using the BeanShell Interpreter class to interpret the string as an equation. But how would I solve for x?

  • emulate dual monitor using a second machine

    - by Hemal Pandya
    I have monitors of my two machines side by side and I use them both with a single keyboard/mouse using Google Synergy+ which works great. But is it possible to use the monitor of my secondary machine as the secondary monitor of my primary? I am on XP so from what I understand I cannot just rdc from secondary to this primary. In any case that would be a different session altogether and I would prefer to be able to extend my desktop over the two monitors. Any solutions or suggestions? Thanks in advance.

  • VLC or ffserver for http streaming

    - by Maciek Sawicki
    Hi, I don't like asking "OR" questions, but I can't find any comparison on the Internet. I need live http streaming using h264 in flv container. I managed to achieve this with VLC, but with big latency. I have some problems with ffmpeg and I can not make it to work, but I wonder if would it works better then VLC?

  • Windows 7 - svchost high cpu usage.

    - by Leonardo
    Hey guys! I'm having a problem with windows 7 x64 i though it was slow and all then i saw that the cpu usage was always around 80% and started digging through google. there's two svchost consuming around 30% each and in the resources monitor there's a system interrupts consuming 45% all the time, i trid closing the aplications and makes no diference. so i tried some other things that i've found on gloogle like disable system update but didn't work. i'd love some help here. i don't know if it will help but here's my specs: Core 2 duo 4400 ATI radeon 4850 4gb ram DDR2 thanks anyway for your attention :) EDIT So i run the program and i got this info, did i get it right? EDIT As you asked here it is, did i get it right now? the other tcp/ip there's nothing. thanks again! :D EDIT I tried somthing here, i run msconfig and took the services that one of the svchost was using out of the startup and now my cpu is around 50%, but i still would like to make this better, i can't lose that much cpu power just because windows... thanks. EDIT yeah there's nothing i can do here, going to install xp for a while, it's really weird...

  • documenting class properties

    - by intuited
    I'm writing a lightweight class whose properties are intended to be publicly accessible, and only sometimes overridden in specific instantiations. There's no provision in the Python language for creating docstrings for class properties, or any sort of properties, for that matter. What is the accepted way, should there be one, to document these properties? Currently I'm doing this sort of thing: class Albatross(object): """A bird with a flight speed exceeding that of an unladen swallow. Properties: """ flight_speed = 691 __doc__ += """ flight_speed (691) The maximum speed that such a bird can attain """ nesting_grounds = "Throatwarbler Man Grove" __doc__ += """ nesting_grounds ("Throatwarbler Man Grove") The locale where these birds congregate to reproduce. """ def __init__(**keyargs): """Initialize the Albatross from the keyword arguments.""" self.__dict__.update(keyargs) Although this style doesn't seem to be expressly forbidden in the docstring style guidelines, it's also not mentioned as an option. The advantage here is that it provides a way to document properties alongside their definitions, while still creating a presentable class docstring, and avoiding having to write comments that reiterate the information from the docstring. I'm still kind of annoyed that I have to actually write the properties twice; I'm considering using the string representations of the values in the docstring to at least avoid duplication of the default values. Is this a heinous breach of the ad hoc community conventions? Is it okay? Is there a better way? For example, it's possible to create a dictionary containing values and docstrings for the properties and then add the contents to the class __dict__ and docstring towards the end of the class declaration; this would alleviate the need to type the property names and values twice. I'm pretty new to python and still working out the details of coding style, so unrelated critiques are also welcome.

  • ASP.NET Session and target blank

    - by Lennart
    Hi I have seen a few posts regarding Session and using target blank to open a new page. But I still don´t get it. Im working with an application which opens from a link on an Intranet site. I guess it uses target blank to get it in a new window. (I don´t have the source). If both windows are closed (My application and the Intranet site) it seems like the Session is destroyed. I need that to happen when my application is closed. (ie, still leaving the Intranet site open). If I use the site in my testenvironment without opening it from a page with target blank, it seems like I get the expected behaviour. Web.config has: pages enableSessionState="true" Thanks
