• Reference Object calling function in Javascript

  - by Louis

  I have a makeshift events system in JS and the attacher looks like this: events.attach(events.NEW_TASK,this.update); Where this.update is a callback/handler/function. The problem is, when the dispatcher tries to call this handler, it loses it's original context. How can I bind the handler with the context of the object that calls the attach function without passing this as an argument and using that?

• odd resharper indentation formatting for object intializers

  - by bitbonk

  For some strange reason when I have nested object intializers it always gets the last '}' wrong. It is not indented at all as shown in the following example: namespace MyNameSpace { internal static class MyClass { static MyClass() { var bla = new Bla { Name = "Bla" }; bla.Blub = new Blub { Name = "Blub", Blap = new Blap { Name = "Blap", Visible = true }, Blob = new Blob { Name = "Blob" }, Blib = new Blib { Blep = new Heater { Name = "Bleb" }, Id = 1, Blap = new Blap { Name = "Blap" } } // <---- wrong !!! }; } } } Any idea what I can do against it ?

• How to do motion tracking of a object using video

  - by Niroshan

  Could someone direct me to a tutorial or guide me how to track motion of a object moving with 6 DOF. I am planing to use a video stream of a moving toy car. I want to calculate displacement and rotation angle of the toy car. I came across some research papers but couldn't find any libraries to the job. Is there a way to do this using OpenCV or Matlab or some other freely available software? Thank you

• How to relink existing shared library with extra object file

  - by awy

  I have existing Linux shared object file (shared library) which has been stripped. I want to produce a new version of the library with some additional functions included. I had hoped that something like the following would work, but does not: ld -o newlib.so newfuncs.o --whole-archive existinglib.so I do not have the source to the existing library. I could get it but getting a full build environment with the necessary dependencies in place would be a lot of effort for what seems like a simple problem.

  - by user576611

  Hi Everyone, I'm specifically using the Google Contacts API at the moment, but this could be true of other scinarios as well.

• Why is Serializable Attribute required for an object to be serialized

  - by Keivan

  Based on my understanding SerializableAttribute provides no compile time checks, as its all done at runtime, then why is it required for classes to be marked as serializable? Couldn't sterilizer just try to serialize an object and just fail? isn't it what it does right-now when something is marked, it tries and fails. wouldn't it be better if you had to mark things as unserializable rather than serializable? that way you wouldn't have the problem of libraries not marking things as serializable?

  - by user327359

  I'm just getting started in Visual Studio 2010 and I'm coming from Delphi 7. In Visual Studio 2010, what is the equivalent to Delphi's Object TreeView? Or to ask it another way, in Visual Studio 2010, during WinForm Gui development, how do you navigate your Gui hierarchically? If I have, say, a bunch of Panels with some of them inside of others and some Docked to Client, how can I directly select a specific Panel?
