My way:
'Ctrl-V' to start blockwise visual mode.
Make your selection.
With the selection still active, 'Shift-I'. This put you into column insert mode.
Type you comment characters '#' or '//' or whatever.
ESC. |

I'd say yes. To me, it just breaks the 'flow' of a fluidly-written piece of code.
Another argument could also be that if you stick to the basic keywords supported by most modern languages, then your program flow (if not the logic or code) could be ported to any other language. Having an unsupported keyword (ie, cont... |

There is a good chance you will not be able to get away with configuration alone.

There's a DefaultValueAttribute that can be assigned to a property, this is mainly used by the designer tools so they can indicate when a property has been changed, but, it might be a "tidy" way of describing what the default value for a property is, and thus being able to identify if it's changed.

One more aspect of the problem which was not mentioned is that the generated code should also be "version control-friendly" (as far as it is feasible).

Calling an event `bind` method (such as `hover`) does not delete old event handlers, only adds your new events, so your idea of 'restoring' the old event functions wouldn't work, as it wouldn't delete your events.

My personal preference is to diligently encode *anything* that's coming from the database, business layer or from the user.
In ASP.Net this is done by using `Server.HtmlEncode(string)` .
The reason so encode anything is that even properties which you might assume to be boolean or numeric could contain malicious c... |

No, when you use automatic properties you don't have any control over the implementation. The best option is to use a templating tool, code snippets or create a private SetValue`<T`>(ref T backingField, T value) which encapsulates the setter logic.

You can't register same DP twice. To comply with this constraint you should use static variable - it will be initialized only one time. |
You can't register same DP twice. To comply with this constraint you should use static variable, it will be initialized only one time thus you will register DP one time only. |
I see 2 reasons behind that requirement:
1. You can't register same DP twice. To comply with this constraint you should use static variable, it will be initialized only one time thus you will register DP one time only.
2. DP should be registered before any class (which uses that DB) instance created |
