• UIPickerView issues - iphone

  - by Rob J

  I have the following: - (NSInteger) numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 2; } - (NSInteger) pickerView:(UIPickerView *) pickerView numberOfRowsInComponent:(NSInteger) component { return [genderPickerData count]; return [agePickerData count]; } When I do this, the UIPicker is split into 2 components, but the PickerData is only being represented for gender on both pickers. I am trying to figure out through Apple's confusing documentation on how I reference each individual component but can't seem to figure it out.

  - by David Nouls

  I need to customize the SSL handshaking when calling a JAX-WS API on top of Axis2. I find no reference at all on how to do this. With Metro I can set a custom SSLSocketFactory, but that uses a non standard API. How do I get access to the Axis engine so that I can reconfigure it before sending a soap request ?

• Updating Commit Message in Mercurial MQ extension

  - by Jerub

  After using hg qnew and hg qrefresh to create and update a patch that I want to apply to my repository, but the commit message that I wrote when I did hg qnew was not very good, it did not reference the ticket number from trac, and I would like to say something in it about some of the issues that my commit addresses. How do I do something like hg qrewritemycommitmessage. I have examined the docs on the website (starting here: http://mercurial.selenic.com/wiki/MqExtension ) and I have come up blank.

• Launch Scala REPL programatically?

  - by David Crawshaw

  I would like to launch a Scala Swing application from the command line, then after the application is started, drop into the Scala REPL to use as a control interface. Ideally I would also like to pre-bind some variable names. Even better would be using a Java2D terminal emulator for the REPL, but I couldn't find anything appropriate. Does the Scala REPL have a public API?

• Working with anonymous modules in Ruby

  - by Byron Park

  Suppose I make a module as follows: m = Module.new do class C end end Three questions: Other than a reference to m, is there a way I can access C and other things inside m? Can I give a name to the anonymous module after I've created it (just as if I'd typed "module ...")? How do I delete the anonymous module when I'm done with it, such that the constants it defines are no longer present?

• jQuery AJAX table to a page but now the colorbox overlays no longer work

  - by RyanP13

  Hi, I am using AJAX to dynamically update a page with a data table. When the table is successfully added to the page it contains some code reference to produce colorbox overlay pop ups. However, after the table has been pulled into the page these overlays no longer function. Any ideas? I assume they need to be re-initialised or something?

  Which way is better practice: return a value from a method inside an using statement or declare a variable before, set it inside and return it after? public int Foo() { using(..) { return bar; } } or public int Foo() { var b = null; using(..) { b = bar; } return b; }

• What is the purpose of the CreateSilverlight.js?

• Modifying multiplying calculation to use delta time

  - by Bart van Heukelom

  function(deltaTime) { x = x * 0.9; } This function is called in a game loop. First assume that it's running at a constant 30 FPS, so deltaTime is always 1/30. Now the game is changed so deltaTime isn't always 1/30 but becomes variable. How can I incorporate deltaTime in the calculation of x to keep the "effect per second" the same?

• Implementing dynamic scope when using CPS as intermediate language

  - by asandroq

  I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

• When are references declared in a switch statement?

  - by sandis

  To my surprise this code works fine: int i = 2; switch(i) { case 1: String myString = "foo"; break; case 2: myString = "poo"; System.out.println(myString); } But the String reference should never be declared? Could it be that all variables under every case always are declared no matter what, or how is this resolved?

• Howto ignore specific undefined variables in Pydev (eclipse)

  - by chris.nullptr

  I'm writing a crossplatform python script on windows using Eclipse with the Pydev plugin. The script makes use of the os.symlink() and os.readlink() methods if the current platform isn't NT. Since the os.symlink() and os.readlink() methods aren't available on the windows platform Pydev flags them as undefined variables--like so: Is there a way to explicitly ignore certain undefined variable name errors (e.g. os.symlink())?

• How to include/require/load a file in ruby with instance variables

  - by doctororange

  I would like to put a large variable definition in a separate file for the sake of getting it out of the way. I must be doing something wrong though, because my puts call isn't putting anything out. my_class.rb: class foobar def initialize require 'datafile.rb' puts @fat_data end end datafile.rb: @fat_data = [1,2,3,4,5,6,7,8,9,10] Can you use require this way?

• How to get ANTLR 3.2 to exit upon first error?

  - by Dan Becker

  In section 10.4, The Definitive ANTLR reference tells you to override mismatch() & recoverFromMismatchedSet() if you want to exit upon the first parsing error. But, at least in ANTLR 3.2, it appears that there is no mismatch() method, and the recoverFromMismatchedSet() documentation says that it is "Not Currently Used". So it appears things have changed since the book was published. What am I supposed to do instead to exit upon the first parsing error in ANTLR 3.2?
