• Write number N in base M

  - by VaioIsBorn

  I know how to do it mathematically, but i want it now to do it in c++ using some easy algorithm. Is is possible? The question is that i need some methods/ideas for writing a number N in base M, for example 1410 in base 3: (14)10 = 2*(3^0) + 1*(3^1) + 1*(3^2) = (112)3 etc.

• Catch requests to non-existent classes (not autoload)

  - by Spot

  Is there a manner in which to catch requests to a class which does not exist. I'm looking for something exactly like __call() and __static(), but for classes as opposed to methods in a class. I am not talking about autoloading. I need to be able to interrupt the request and reroute it. Ideas?

  I have a property public ObservableCollection<string> Name { get { return _nameCache; } } _nameCache is updated by multiple threads in other class methods. The updates are guarded by a lock. The question is: should I use the same lock around my return statement? Will not using a lock lead to a race condition?

  I'm creating a VB.NET application that includes two radio buttons inside of a groupbox. If the first radio button is selected, a certain tab on a tab form should be enabled. If the second radio button is selected, that tab should be disabled. Is there a groupbox method that monitors both radio buttons and fires when the selection changes? Or do I need to set up individual methods for each radio button?

• Java: If I overwrite the .equals method, can I still test for reference equality with ==?

  - by shots fired

  I have the following situation: I need to sort trees based by height, so I made the Tree's comparable using the height attribute. However, I was also told to overwrite the equals and hashCode methods to avoid unpredictable behaviour. Still, sometimes I may want to compare the references of the roots or something along those lines using ==. Is that still possible or does the == comparison call the equals method?

• Static member class - declare class private and class member package-private?

  - by Helper Method

  Consider you have the following class public class OuterClass { ... private static class InnerClass { int foo; int bar; } } I think I've read somewhere (but not the official Java Tutorial) that if I would declare the static member classes attributes private, the compiler had to generate some sort of accessor methods so that the outer class can actually access the static member class's (which is effectively a package-private top level class) attributes. Any ideas on that?

• samsung netbook OS for clean install

  - by Alex

  Hello - I recently had a problem with a corrupted registry on a samsung N120. When all else failed i reformatted the drive. However having bought the machine with windows home ed pre-installed, I didn't have original windows disck for the clean install. So I managed to install another edition of windows XP (PRO this time). Now windows opens, but several key functions are missing. e.g.: screen resolution - will not allow me any but 800x600 resolution native buttons - such as the fn + screen brightness is not working at all. Any suggestions please? ? Is there a way to get the samsung OS online (since I do have the manufacturer's/installed product key)? thanks PS: It has been my intention to install ubuntu, but i need to know i will not lose functions like screen brightness, volume, and the trackpad's scrolling function. I'd be happy to bypass the windows option if i was sure to have full keyboard/samsung functionality

• Downside to including headers in every source file (Objective-C)

  - by Michael Waterfall

  I'm currently including my AppDelegate.h and all of my category headers into every one of my source files using the MyApp_Prefix.pch prefix header, instead of manually #importing them only where they are used. The category methods and lots of compiler #define's in my app delegate are used in lots of places in my code. Is there any down side to this? Is it just that compilation will take longer?
