React-native – Draw horizontal rule in React Native

react-native

I've tried react-native-hr package – doesn't work for me nor on Android nor on iOS.

Following code is also not suitable because it renders three dots at the end

<Text numberOfLines={1}}>               
    ______________________________________________________________
</Text>

You could simply use an empty View with a bottom border.

<View
  style={{
    borderBottomColor: 'black',
    borderBottomWidth: 1,
  }}
/>

Asp – fileUpload control appearance

how could I control the "browse" button, just like any other button?

What makes you sure there will be a browse button? That's up to the web browser; some might not have a text-plus-browse arrangment at all. In particular Safari arranges the control quite differently.

For reasons of security, and because there is no standardisation about what a file upload control should look like, CSS gives you almost no control of the style of file upload controls.

Whilst the opacity hack mentioned in phoenix's link does kind of work, I wouldn't recommend it at all. There's no guarantee of getting the ‘clickable’ part of the input control lined up with the part of your ersatz control that looks clickable. Even on a single browser, different fonts and other settings will mess it up. For example on my browser with the quirksmode example only the right half of the textbox is clickable to open the browse dialogue; clicking the faux-button does nothing and clicking the left edge of focuses the faux-textbox. With fake-input you will be offering a shoddy and in the worst case broken experience to many of your visitors.

Live with the default upload styling, or augment it with a Flash uploader in the progressive-enhancement manner.

C# – Permutations of a given set of numbers

The simplest approaches are the recursive ones, i.e., in executable pseudocode;

def permute(theseq):
  if len(theseq) <= 1:
    yield theseq
    return
  for i in range(len(theseq)):
    theseq[0], theseq[i] = theseq[i], theseq[0]
    for subperm in permute(theseq[1:]):
      yield theseq[:1] + subperm
    theseq[0], theseq[i] = theseq[i], theseq[0]

in case you're not familiar with executable pseudocode, the notations [1:] and [:1] are meant to denote "slices" (respecively "all but the first" and "just the first"), and the two identical assignments performs the tasks of "swap the 0th and ith items" and "put them back in place" (i.e. swap them again;-). yield means "provide this result but be ready to continue when iterated on", while return means "we're all done, bye bye!".

There are somewhat better approaches along different axes of performance, but the first milestone is making sure you're totally familiar with the fundamental recursive approach and understand it thoroughly -- so I'm stopping here for now. If and when you do fully understand this approach, why it woks just fine and dandy, and how and why it doesn't really seem optimal in performance, I'll be happy to expand on this answer!-)
