Perhaps you should look at having both client-side and server-side validation. If anything slips past the client-side validation you can then feel free to throw an exception if your business object would be made invalid.
One approach I've used was to apply custom attributes to business object properties, which descr... |

as a SingleCall type, your SampleObject will be created for every call the client makes. This suggests to me that your object is at fault, and you don't show what it does. You need to look at any dependancies it has on shared resources orlocks. Try writing some debug out in the SampleObject's constructor to see how far... |
Time Parsing in Flex |

Is there any way to parse a string in the format HH:MM into a Date (or other) object using the standard libraries?
I know that I can parse something like "9/17/2008 10:30" into a Date object using
var date:Date = new Date(Date.parse("9/17/2008 10:30");
But I want to parse just 10:30 by itself. The followi... |

Too lazy to actually write it up myself, but you should be able to use a mathematical converter and bind to your parent windows width (either by name, or with a RelativeSource ancestor search).

Have you considered prepending "01/01/2000 " to the time string and then applying Date?
Alternately there's probably a tokenizer that will take the input and split it up at the : giving you an array of strings you can convert to integers. A tokenizer isn't hard to write, either, and can be fun if one doesn't exist ... |
Microsoft has never made those claims but they ARE making moves in the WORA arena. Silverlight 2.0 for example will use a subset of the .NET framework and be available on Windows, Linux (through the Moonlight project), MacOS, Windows Mobile, and Nokia handsets.

While not solving the problem of brute force (as others already mentioned) you might want to sort your numbers first, and then go over the possible ones left (since once you passed Sum value, you can't add any number larger than Goal - Sum).

You can create some sort of index and it might get faster.
We can build a index like this:

Your problem does not concern XML: it concerns character encodings.

Well not really elegant. We created our own tool that uses the reportingservices2005 web service. We found this to be the most reliable way of getting what we want.
It's not really that difficult and lets you expand it to do other things like creating data sources and folders as required. |
We do this by shelling out to gnuplot to generate the charts as PNGs server-side. It's a bit old-school and the charts aren't interactive but it works and is cacheable.
