This is all personal preference. When it gets compiled it turns out to be getter/setter functions either way.
I personally use properties when setting and retrieving member values without any side affects. If there are side affects to retrieving/saving the value, then I use a function. |

There's no way to remove these dotted focus in Firefox using CSS.

I think a much better solution would be refactoring the code, so instead of the (yet under-supported) remoting, use web services. XML serialization of most basic data types are IIRC fully supported; and in certain circumstances, fits the architecture much better (especially server-client architectures). |
It looks like the only way to achieve this is by setting
browser.display.focus_ring_width = 0
in about:config on a per browser basis. |
The ListView gives you full control about how the data is rendered to the client. You specify the Layout Template, and give a placeholder which will be where each item is injected.
The output of the below will give you a table, and each item will be a new TR.

There is a missing factor here .. most applications have a 'buckling' factor where crashes suddenly start "costing" a lot more because people loose confidence in the service your app is providing. Once that happens then it can be **very** costly to get users back to trusting and using the system. |
I've not seen any studies, but a reasonable heuristic would be something like :
( Time since last application save when crash occurred + Time to restart application ) * Average hourly rate of application operator.
The estimation gets more complex if the crashes have some impact on external customers such, or migh... |

I didn't use CodeSite probably because I'm completely happy with SmartInspect. Highly recommended. |
I tend to group things thematically for lack of a better word.

I would user something like CAS:

This is a solved problem and wouldn't recommend rolling your own. |
I tend to group methods that relate to each other. Use of a good IDE removes much of this concern. Alphabetizing methods seems like a waste of effort to me. |
What I do is wrap the smart order with a class that takes __FUNCTION__ and __LINE__ parameters. Increment a count for that function and line every time the constructor is called, and decrement the count every time the destructor is called. then, write a function that dumps the function/line/count information. That tell... |

Yes, but the free community edition that comes with Visual Studio has a map functionality.

you can even use them for layouting, if your layout is somewhat tabular. I like the feature of tables and cells dynamically adjusting to whatever width the browser window is.

Have you considered just not using an artificial key for the `LeadSource` table? Then you get to use `LeadSource` as the FK in `SalesLead`, which simplifies your queries while retaining the benefits of using a canonical set of values (the rows in `LeadSource`). |

You can use the return code of the process for that. If your process returns a non-zero value from its Main method, you can then check whether or not the process exited by itself (the return value matches). |
