• Can you transport a Javascript object to server and receive it in the same state?

  - by zorglub76

  I'm considering creating a simple remote debugging application for Javascript. Actually, I want to provide an object to Firebug Lite and let it do all the job. So, can I get an object from one page, serialize it, send it to server and then to another browser and finally see the same results in Firebug Lite (on that other client) as I would see on the first browser (with doing "console.dir(obj)")? Is it possible to do?

• How can an object not be compared to null?

  - by ProfK

  I have an 'optional' parameter on a method that is a KeyValuePair. I wanted an overload that passes null to the core method for this parameter, but in the core method, when I want to check if the KeyValuePair is null, I get the following error: Operator '!=' cannot be applied to operands of type System.Collections.Generic.KeyValuePair<string,object>' and '<null>. How can I not be allowed to check if an object is null?

• Are there any concerns I should have about storing a Python Lock object in a Beaker session?

  - by Jack

  There is a certain page on my website where I want to prevent the same user from visiting it twice in a row. To prevent this, I plan to create a Lock object (from Python's threading library). However, I would need to store that across sessions. Is there anything I should watch out for when trying to store a Lock object in a session (specifically a Beaker session)?

• Where is the VB.Net debugger "Make Object ID" function?

  - by Josh

  When using the visual studio 2008 debugger with c# i can right-click on a variable and choose "Make Object ID" which allows me to watch that object (via it's ID) regardless of whether it is in the current stack frame or not. When the debugger is in VB code, (doesnt matter if it's run from a c# unit test or a vb unit test) That option isn't there. Where did VB put this feature? Or does it simply not support it like so many other helpful c# features?

• How to remove a single, specific object from a ConcurrentBag<>?

  - by routeNpingme

  With the new ConcurrentBag<T> in .NET 4, how do you remove a certain, specific object from it when only TryTake() and TryPeek() are available? I'm thinking of using TryTake() and then just adding the resulting object back into the list if I don't want to remove it, but I feel like I might be missing something. Is this the correct way?

  - by Johan

• Best way to manage JSON object via GET and POST in php.

  - by Kucebe

  My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

• JQuery UI: is it possible to know where an object has been dropped?

  - by Jack Duluoz

  Hi, what I want to do is to know where (not in terms of position (x, y), but a reference to the DOM element) an object was dropped. I have a grid made up with divs where you can drop various items and I need to know which div on the grid was the item dropped on (getting its id would be fine). The callback function function(event, ui) { //code here } has just that ui object who doesn't apparently contain any information about this, but only about the draggable item or its helper.

• How can I declare an object with properties that I will be passing around inside of my function using Typescript?

  - by Marilou

  I've been using the following: var modal = { content: '', form: '', href: '' } But now I have started to use Typescript is there a better way I can declare an object and how can I declare the types of my properties. The reason I am using this object is that it's inside of a function and inside that function I have other functions that set and use the values of the properties. Is this the best way for me to do this or is there another way I could better do this with typescript?

• How to assign a value of a property to a var ONLY if the object isn't null

  - by Blankman

  In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.

• In Ruby, how to write a method to display any object's instance variable names and its values

  - by Jian Lin

  Given any object in Ruby (on Rails), how can I write a method so that it will display that object's instance variable names and its values, like this: @x: 1 @y: 2 @link_to_point: #<Point:0x10031b298 @y=20, @x=38> I also want to be able to print <br> to the end of each instance variable's value so as to print them out nicely on a webpage. the difficulty now seems to be that not every instance variable has an accessor, so it can't be called with obj.send(var_name) (the var_name has the "@" removed, so "@x" becomes "x")
