My DataView is acting funny and it is sorting things alphabetically and I need it to sort things numerically. I have looked all across the web for this one and found many ideas on how to sort it with ICompare, but nothing really solid.
So my questions are

***What platform are you looking for?*** What library you use will depend on this.
For the XNA framework, Farseer is pretty nice. |
Use Eclipse integration, it works perfectly fine.
The main change from CVS, is that you only merge deltas from a branch, ie changes from one revision to another.
That is to say you have to track the correct start revision somehow (unless you have svn 1.5 merge history)
If you got that right, it's only up to you ... |
I feel like outvoted so far, but I'll vouch for one of:

else funcB();
To me, the shorthand format is nice when you want it to read like English grammar. If... |
I had a similar issue with a localization component that I wrote. My component is designed to access localized messages with enum constants that index into a resource bundle, not a hard problem.

If you're generating the page that links to the JS files a simple solution is appending the file's last modification timestamp to the generated links.
This is very similar to Huppie's answer, but works in version control systems without keyword substitution. It's also better than append the current time, since that... |
According to the docs, you can do something like this:

<cfinvoke component="#tellTimeObj#" method="getLocalTime" returnvariable="localTime">

Your question could use some clarification as to exactly what aspects of translation / localization you need help with. Do you need help extracting strings from code? Tracking down improper use of non-localizable String.Formats in code (i.e. mm/dd/yyyy vs. dd/mm/yyyy)? Help managing all the resources once you've ext... |
You can use cfinvoke. You don't have to specify a component.
<cfinvoke method="application.#funcName#" argumentCollection="#params#">
|
Note that concurrency doesn't magically give you more resource. You need to establish what is slowing CalculateSmth down.
For example, if it's CPU-bound (and you're on a single core) then the same number of CPU ticks will go to the code, whether you execute them sequentially or in parallel. Plus you'd get some overh... |

I think perhaps the right way to do this would be an extender provider: [MSDN documentation][1]

One classic suggestion for a string hash is to step through the letters one by one adding their ascii/unicode values to an accumulator, each time multiplying the accumulator by a prime number. (allowing overflow on the hash value)

@Lou: It would be just syntactic sugar for:

I agree this is one area that PHP's documentation has dropped the ball, but for me I've always used the SimpleXML mixed with something like the xml2Array functions. The Xml you get from simpleXML isn't that hard to navigate with the help of a dumping function like print_r. |
