• 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.

• What groupbox method (if any) monitors radio button selections?

  - by JohnK813

  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?

• Business object and linq2SQL

  - by Overdose

  What is the optimal way to write the code which interacts with DB using linq2SQL? I need to add some business logic to the entities. So I guess there are two ways: Write some wrapper class. The main minus is that many fields are the same, so i don't feel it as DRY style. Add business logic methods to linq2sql entities(these classes are partial) directly ???

• Zend_Db_Select where() and Zend_Db_Adapter quoteInto()

  - by Chris

  Are Zend_Db_Select's where() method, when including the optional value to quite into, and Zend_Db_Adapte's quoteInto() methods basically the same as far as escaping SQL? In other words, are these two pieces of quote identical and equally secure? $select->where($this->getAdapter()->quoteInto('id = ?', 3)); $select->where(id = ?, 3); Thanks!

• Why do these seemingly similar queries have such drastically different run times?

  - by Jherico

  I'm working with an oracle DB trying to tune some queries and I'm having trouble understanding why working a particular clause in a particular way has such a drastic impact on the query performance. Here is a performant version of the query I'm doing select * from ( select a.*, rownum rn from ( select * from table_foo ) a where rownum < 3 ) where rn >= 2 The same query by replacing the last two lines with this ) a where rownum >=2 rownum < 3 ) performs horribly. Several orders of magnitude worse ) a where rownum between 2 and 3 ) also performs horribly. I don't understand the magic from the first query and how to apply it to further similar queries.

• 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?

• 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?
