• Replace a control on the screen

  - by Rob Bonner

  Hello all, I have an instance of a FlowCoverView (a great library that emulates cover flow on the iPhone). And it works great, with the exception of an update. When I update my table behind the scenes, I have no way of telling this control (that is defined in IB) that it has been updated, and to reload. (much like you can with a table using reloadData) To the question, is there a way to replace a control that is on the screen with another control to force the reload?

• C# 'could not found' existing method

  - by shybovycha

  Greetings! I've been fooling around (a bit) with C# and its assemblies. And so i've found such an interesting feature as dynamic loading assemblies and invoking its class members. A bit of google and here i am, writing some kind of 'assembly explorer'. (i've used some portions of code from here, here and here and none of 'em gave any of expected results). But i've found a small bug: when i tried to invoke class method from assembly i've loaded, application raised MissingMethod exception. I'm sure DLL i'm loading contains class and method i'm tryin' to invoke (my app ensures me as well as RedGate's .NET Reflector): The main application code seems to be okay and i start thinking if i was wrong with my DLL... Ah, and i've put both of projects into one solution, but i don't think it may cause any troubles. And yes, DLL project has 'class library' target while the main application one has 'console applcation' target. So, the question is: what's wrong with 'em? Here are some source code: DLL source: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ClassLibrary1 { public class Class1 { public void Main() { System.Console.WriteLine("Hello, World!"); } } } Main application source: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Assembly asm = Assembly.LoadFrom(@"a\long\long\path\ClassLibrary1.dll"); try { foreach (Type t in asm.GetTypes()) { if (t.IsClass == true && t.FullName.EndsWith(".Class1")) { object obj = Activator.CreateInstance(t); object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, null); // Exception is risen from here } } } catch (Exception e) { System.Console.WriteLine("Error: {0}", e.Message); } System.Console.ReadKey(); } } } UPD: worked for one case - when DLL method takes no arguments: DLL class (also works if method is not static): public class Class1 { public static void Main() { System.Console.WriteLine("Hello, World!"); } } Method invoke code: object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, null, null);

• What is the most performant 2D graphics engine for use with Android?

  - by nbolton

  I have managed to make a hello world JBox2D application, and it works (I have some bouncing balls). However, I just read a comment on a forum post, which claims that JBox2D produces a lot of garbage, and so causes animation to be poor. Is this true? If yes, then what other 2D engines are available to me? I would very much like to use a physics engine for my 2D game, even if it's just a very simple one.

• Troubles with a PHP session variable after form submission

  - by Psyche

  Hello, I'm setting a PHP session variable with a success message for a HTML form that I'm submitting. If there are no form errors, I redirect to the same page (using header()) and display the message from the session variable. Everything is fine until here, but if I access that page again after submission, the message is still there. Is it possible to make it appear only when I redirect after a successful submit? Thank you.

• Where can I find documentation for Scala's delayed function calls?

  - by Geo

  I saw a delayed example in David Pollak's "Beginning Scala". I tried to adapt that, by trial and error. Here's what I have: def sayhello() = { println("hello") } def delaying(t: => Unit):Unit = { println("before call") t println("after call") } delaying(sayhello()) How would you delay a function/method that takes parameters? Why can't I use parantheses when I call t? Where can I find more documentation on delaying functions?
