Proper way to implement a never ending task. (Timers vs Task) So, my app needs to perform an action almost continuously (with a pause of 10 seconds or so between each run) for as long as the app is running or a cancellation is requested. The work it needs to do has the possibility of taking up to 30 seconds. Is it better to use a System.Timers.Timer and use AutoReset to make sure it doesn't perf..

Run all of Xcode's “Fix-it”s at once After upgrading to Xcode 7, to support iOS 9, i have hundreds of fix-it errors and warnings. Is there a one push button to make Xcode run them all rather then individual going through them one by one? There is actually a solution for this in Xcode 7.21's Editor menu. This is the shortcut: ⌃+⌥+⌘+f which is ctrl+alt+cmd+f 1 This is the version I can confirm, mi..

Commenting code in Notepad++ I'm using Notepad++ as an editor to write programs in Python. It might sound daft but I looked around in the editor and could not find any means (not the manual way but something like in Emacs) to do a block comment in my code.

Nullable vs. int? - Is there any difference? Apparently Nullable and int? are equivalent in value. Are there any reasons to choose one over the other? Nullable a = null; int? b = null; a == b; // this is true No difference. int? is just shorthand for Nullable, which itself is shorthand for Nullable. Compiled code will be exactly the same whichever one you choose to use. The ? form is just a shor..

How to Add a Dotted Underline Beneath HTML Text How do you underline html text so that the line beneath the text is dotted rather than the standard underline? Preferably, I would like to do this without using a separate CSS file. I'm a novice at html. It's impossible without CSS. In fact, the tag is simply adding text-decoration:underline to the text with the browser's built-in CSS. Here's what ..
