Difference between ObservableCollection and BindingList
...ervableCollection<T> is typically derived for the same reason as its base Collection<T> class: for customizing add/remove items (eg. in a data model collection) rather than adjusting binding features.
Copy vs. wrapping
Both ObservableCollection<T> and BindingList<T> have a...
Difference between webdriver.Dispose(), .Close() and .Quit()
... I also noticed that the IEDrivers that are used for working with IE based automation does not exit if you use driver.close() method. I had to use driver.quit() to terminate it. It is because the quit() method also appears to clean up resources unlike close(), although, in my example, I have a...

Differences between unique_ptr and shared_ptr [duplicate]
...f you create a unique_ptr<Derived>, then convert it to unique_ptr<Base>, and if Derived is virtual and Base is not, then the pointer will be deleted through the wrong type and there can be undefined behaviour. This can be fixed with an appropriate deleter-type in the unique_ptr<T, Del...
Getting all types that implement an interface
...ng able to activate a type would be when the type returned is derived from base but base is defined in a different assembly from that of derived, an assembly that the calling assembly does not reference.

Class A // in AssemblyA
Class B : Class A, IMyInterface // in AssemblyB
Class...
How to get hex color value rather than RGB value?
...
Here is the cleaner solution I wrote based on @Matt suggestion:
function rgb2hex(rgb) {
rgb = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
function hex(x) {
return ("0" + parseInt(x).toString(16)).slice(-2);
}
return "#" + hex(rgb[1]) ...
Why can Java Collections not directly store Primitives types?
...sues: relatively efficient access would require keeping both arrays sorted based on the key order to allow binary searching, which in turn would make insertion and deletion inefficient unless the insertion/deletion is patterned such that inserted items are likely to end up where a previously deleted...

A lexical environment is a mapping between identifier names and the values associated with them.
Scope is formed of a linked nesting of lexical environments, with each level in the nest...
Why avoid increment (“++”) and decrement (“--”) operators in JavaScript?
...operation. push is array[++i] = foo, pop is bar = array[i--]. (But with 0-based arrays, array[i++] = foo and bar = array[--i] look still better). Another thing, I would hate it if someone added extra code between i++; and array[i] = foo;.
