Does it start at the begining of a line or can it appear anywhere? If the former s/old/new is what you want. If the latter, I'll have to figure that out. I suspect that back referances could be used somehow. |

Since this question is tagged with regex, I decided to try a regex approach. I first replace all the spaces in the quotes parts with \x00, then split by spaces, then replace the \x00 back to spaces in each part.
Both versions do the same thing, but splitter is a bit more readable then splitter2.

Keep in mind whenever you're splitting by "word" anywhere that some languages such as Chinese and Japanese do not use a space character to split words. Also, a malicious user could simply enter text without any spaces, or using some Unicode look-alike to the standard space character, in which case any solution you use ... |

There's an automated test tool called [RIATest][1] that might fit the bill for you.

Generally, if you must have the BEST indexed lookup performance it's best to build a List<T> first and then turn it into a array thus paying a small penalty at first but avoiding any later.

Below are two ways of reading in the commandline parameters. The first is the way that I'm accustom to seeing using the parameter in the main. The second I stumbled on when reviewing code.

I don't think you can create non-zero based arrays in C#, but you could easily write a wrapper class of your own around the built in data structures.This wrapper class would hold a private instance of the array type you required; overloading the [] indexing operator is not allowed, but you can add an indexer to a class... |
I use [ArtisticStyle](http://astyle.sourceforge.net/) (C++) to do this and also reformat my code. However I had to add this as external tool and you need to trigger it yourself so you might not like it.

You may have to use a regular JTextField and call setDocument() with a custom document. I recommend extending PlainDocument, this makes it easy to validate input as the document changes, and add slashes as appropriate. |
Class variables are scoped according to their member visibility attributes, and have global storage, not thread storage.
Scope is a syntactic concept, and relates to what identifiers are visible from where. It is the storage of the variable that is of concern here. |

You could have a limited amount of instances of each type in a pool, and reuse the already done with instances. The size of the pool would depend on the amount of messages you'll be processing. |
The answer is *NEVER*. If you need to write programs to load or process data you need to do it outside of your data tier from another computer on the network.

I found WROX's Professional .NET 2.0 Generics very useful as it contains lots of real world examples.

Personally, I find .NET Generics most useful in simplifying the defining a... |
Are you collecting both the start time and stop time? If so, you could use the "timestamp" data type, if your DBMS supports that. If not, just as a date/time type. Now, you've said you don't want the date part to be stored - but consider the case where the time period spans midnight - you start at 23:55:01 and end a... |
Forcing a GC.Collect() is generally a bad idea, leave the GC to do what it does best. It sounds like the best solution would be to use a pool of objects that you can grow if necessary - I've used this pattern successfully.
This way you avoid not only the garbage collection but the regular allocation cost as well.

Here's an even simpler implementation. All you do is take a snapshot of the stage using the **draw()** method of bitmapData, then use **getPixel()** on the pixel under the mouse. The advantage of this is that you can sample anything that's been drawn to the stage, not just a given bitmap.

You can do all of your compiling exclusively on Java6 and then use System.getProperty("java.version") to conditionally run either the Java5 or the Java6 code path.

The first answer:
string s = ",liger, unicorn, snipe";

Because a class that has a read-only property (no setter) probably has a good reason for it. There might not be any underlying datastore, for example. Allowing you to create a setter breaks the contract set forth by the class. It's just bad OOP. |

I would have to assume that the viewstate contains information for each of a Multiview's views/controls. Otherwise, there's no way it would be able to keep track of the state of the controls in each view- unless you were using some sort of custom state management. |
To add to Aeon's answer, it depends on the the thing and what you want to do to it. So if you are writing Thing, and DoSomething alters the internal state of Thing, then the best approach is Thing.DoSomething. However, if the action does more than change the internal state, then DoSomething(Thing) makes more sense. For... |
