  std::string x(x); This crashes very badly on my compiler. Does this mean I should test for this != &that in my own copy constructors, or can I assume that no client will ever be so stupid?

• T-SQL String Functions: difference between using Left/Right and Substring and strange behaviour

  - by TheObserver

  I am using SQL Server 2008 & 2005 (Express). I'm trying to extract part of an alpha numeric string from a varchar field. RIGHT(str_field,3) yields null values but substring(str_field, len(str_field)-2, len(str_field)) gives the right value. left(str_field,7) gives the expected values. What gives? I would have thought that RIGHT(str_field,3) and substring(str_field, len(str_field)-2, len(str_field)) are equivalent expressions.

• How to make CodeIgniter accept "query string" URLs?

  - by Peter

  According to CI's docs, CodeIgniter uses a segment-based approach, for example: example.com/my/group If I want to find a specific group (id=5), I can visit example.com/my/group/5 And in the controller, define function group($id='') { ... } Now I want to use the traditional approach, which CI calls "query string" URL. Example: example.com/my/group?id=5 If I go to this URL directly, I get a 404 page not found. So how can I enable this?

• PHP Find and replace after in a string?

  - by TheBlackBenzKid

  I have some strings which contain the words LIMIT 3, 199 or LIMIT 0, 100. Basically I want to replace the word LIMIT and everything after it in my string. How do I do this in PHP? str_replace only replaces an item and the LIMIT text after is dynamic/ So it could be WHEN JOHN WAS TRYING HIS SQL QUERY, HE FOUND THAT LIMIT, 121 // RETURN WOULD BE WHEN JOHN WAS TRYING HIS SQL QUERY, HE FOUND THAT WHEN JOHN TRIED LIMIT 343, 333 HE FOUND // RETURN WOULD BE WHEN JOHN TRIED

• allocing an object based on a string name

  - by Roger Gilbrat

  Is there a way in objective-c/Cocoa to alloc an object when the class name isn't know until run-time. I seem to remember something about this a while ago, but can't find anything on it now. Something like: [[@"MyClass" alloc] init]; I seem to recall a function that would return some kind of class id based on a string that can then be used to alloc the object.

• Working with PHP Octals and String conversions

  - by krio

  I'm working with a database that has a bunch of serial numbers that are prefixed with leading 0's. So a serial number can look like 00032432 or 56332432. Problem is with PHP I don't understand how the conversion system with octals works. A specific example is that I'm trying to convert and compare all of these integer based numbers with strings. Is it possible to convert an octal, such as 00234 to a string like "00234" so that I can compare it?
