I have a list of data object to sort. I want to do something like
<pre>list.sort(function(item1, item2){
return item1.attr - item2.attr;
})
</pre>
to sort it based on a string attribute of the object. But found that the minus(-) operator does not work for strings in javascript. So how do you do string compari... |
Sorry, stupid question. You should use > or < and == here. So the solution would be:
<pre>
list.sort(function(item1, item2){
var val1 = item1.attr;
var val2 = item2.attr;
if (val1 == val2)
return 0;
if (val1 > val2)
return 1;
if (val1 < val2)

Saw a mention of List.ForEach above; 2.0 introduced a bevy of predicate-based collection operations - Find, FindAll, Exists, etc. Coupled with anonymous delegates you can almost achieve the simplicity of 3.5's lambda expressions. |
Well, this oughta work...
if ( item1.attr < item2.attr )
return -1;
if ( item1.attr > item2.attr )
return 1;
return 0;

**[Edit:** uh, and i guess you could also use `localeCompare()`...

How do I stop visual studio from automatically inserting asterisk during a block comment? |
|visual-studio|tips-and-tricks| |
I'm tearing my hair out with this one. If I start a block comment ( /* ) in VS.NET 2005+ then carriage return, VS insists that I have another asterisk ( * ). I know there's an option to turn this off but I just can't find it. Anyone know how to turn this feature off? |

You could try the approach used by code generation tools like CodeSmith. Create a SQL template with placeholders. At runtime, read the template into a string and substitute the placeholders with actual values. This is only useful if all the SQL code follow a pattern. |
I've used [XmlUnit][1] in the past and found it to be useful.
It can be used to validate XML against a schema or compare your XML against a string. It is clever enough to understand XML's parsing rules.
For example it knows that "<e1/>" is equivalent to "<e1></e1>" and can be configured to ignore ... |

Migrating a bigger project like this from as2 will be more than a simple search and replace.

You'll probably be better off ... |

This is equivalent to the backtick solution:

http://cs-sdl.sourceforge.net/index.php/Main_Page is the solution I've come to love. If you need 3d on top of it, you can use Tao.OpenGL to render inside it. It's fast, industry standard (SDL, that is), and cross-platform. |
I suspect the problem may be that there are spaces in one of the directory names. For example, if your working directory is "/home/user/music/artist name". Bash will be confused thinking that you are trying to redirect to /home/user/music/artist and name.txt. You can fix this with double quotes

In my opinion in most cases DTO objects are not needed when dealing with LINQ. Generated LINQ classes can be easily tested. LINQ gives you ability to query your data from different sources using identical queries. It gives you ability to test your queries against lists of objects instead of real db. |

It is very common and generally a good practice for any build process to do a 'clean' before doing any significant build. This prevents any 'artifacts' from previous builds to taint the output.
A clean is essentially what you are doing by deleting the working copy. |
