• Add a custom jquery validation method not connected to a field

  - by Johan Wikström

  Normally all validation methods is connected to a field, radiobuttons, dropdowns etc. In my case I would like to do a general custom validation that depends on many fields in my form. I dont want one field of them to become highlighted like a normal "required", i would rather just show a message in the errorcontainer. Is there a simple way to do this I have overlooked?

• Is it standard behavior for this code to throw a NullPointerException?

  - by Eric

  I've had a big problem in some library code, which I've pinned down to a single statement: System.out.println((String) null); Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException. In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?

• Given a PHP class would be the best and simplest way to override one or two of its methods with one

  - by racl101

  Here's the objective. I have a PHP class and there are one or two of its methods that I would like to override with my own. As I understand OOP (in PHP and in general) I could write a child class that extends it and overrides the functionality of the methods in question. However, I was wondering if this is the best way of achieving this task and if this is a proper use for child classes or if there is something better in PHP for what I'm trying to do.

  On Unix, is there any way that one process can change another's environment variables (assuming they're all being run by the same user)? A general solution would be best, but if not, what about the specific case where one is a child of the other? Edit: How about via gdb?

• C++[MSVC2010]: How does switch compile and how optimized and fast is it?

  - by ekul

  As I found out that I can use only numerical values in C++'s switch statements, I thought that there then must be some deeper difference between it and a bunch of if-else's. Therefore I asked myself: (How) does switch differ from if-elseif-elseif in terms of runtime speed, compile time optimization and general compilation? I'm mainly speaking of MSVC here.

• Creating 3rd party library in Android. Need suggestions!!

  - by Lalith

  Hello all, I am planning to create a 3rd party library for android application developers. Also the main concern is I do not want the users to make many changes to their code base. The following are the main things I want to clarify before diving into the project. 1) I want to attach my own event handlers dynamically to the application. As per above limitations I mentioned, I cannot make users put the relevant code in their handlers as I need to support existing applications as well. I found out that we cannot attach more than one event handler per one listener. For example Button.setOnclickListener(somelistener) .. will set one listener. In traditional desktop applications we can add more than one handlers but here if I do one more Button.setOnclickListener(someOtherListener) this one overwrites the previous listener. Is there any way I can attach my own listener along with application's existing listeners dynamically? Also is it really not supported on android yet? 2) Is there any 3rd party alternative that exists already that monitors user's interactions in androidi? 3) If this is not supported now are there any future plans to support this feature? Please let me know about this as I did not get much feedback on Stackoverflow. Any suggestions and workarounds would really help me continue with this project. Regards, Lalith

• What is a .NET application domain?

  - by Luke

  In particular, what are the implications of running code in two different application domains? How is data normally passed across the application domain boundary? Is it the same as passing data across the process boundary? I'm curious to know more about this abstraction and what it is useful for. EDIT: Good existing coverage of the AppDomain class in general at http://stackoverflow.com/questions/622516/i-dont-understand-appdomains
