If you are aware of any example implementations please share :) 回答1: The first step would be to break up the text into

问题 I know in Galaxy Samsung SIII it is possible to configure in settings an option to avoid the screen turns off when user is looking into the screen. I think the phone uses the camera or a kind of a sensor of presence. is it possible to do it programmatically? even if yes, some devices won't be capable to do that. I imagine some possibilities here: using the camera, accelerometer, or even user activity: if the screen is on, touches, I don't know. There is a specific library about "user presence

阅读更多关于 Multiple Key Gestures for custom keyboard shortcuts in WPF

Does anyone know if it's possible to have key combinations for keyboard shortcuts in WPF? Right now if I want to use CTRL + S as a shortcut I can do the following: InputGestures.Add( new KeyGesture( Key.S , ModifierKeys.Control )); But if I want to use CTRL + S , D ...

I'm trying to get simple user input in Ruby, but I can't get it working. I'm using the gets method, but the program never stops to ask me for input. I'm using Sublime Text 2 as my text editor, and I run the program in it, too (if this makes a difference). Here's my code: puts "What is your name?" name = gets puts "Hello " + name + ". How are you?" And here's the error (and output) given to me: C:/Users/Sten Sootla/Desktop/Ruby workspace/exercise.rb:3:in `+': can't convert nil into String (TypeError) from C:/Users/Sten Sootla/Desktop/Ruby workspace/exercise.rb:3:in `' What is your name?

阅读更多关于 Javascript search and display divs with matching keywords

问题 What I'm looking for: I'm working on creating an easy way for a user to search a list of people, and for results to instantly display below the search field. The results MUST display "close" results, rather than exact. For example: User searches for "Mr. Smith" and The following existing result is displayed: "John Smith" (since there is no "Mr. Smith" entry, it displayed one with the keyword "smith") What I have: I have a working code that lets the user enter some characters and all divs that

问题 Note: I take care of SQL injection and output escaping elsewhere - this question is about input filtering only, thanks. I'm in the middle of refactoring my user input filtering functions.

What is the fastest way to determine a key press and key holding in Win32?

阅读更多关于 What is the fastest way to determine a key press and key holding in Win32?

问题 What is the fastest way to determine a key press and also how to determine if a key is being held? It appears that window messaging is slow. Please provide an example of how to do so, and why it is faster than an alternative. To be clear, this for a real time loop (a simulation) so I am looking for the fastest way to determine if a key has been pressed and also to check to see if it is being held. 回答1: GetAsyncKeyState() is what you're looking for. It reads the physical state of the keyboard,

Currently I have something like makeAThingExcept :: String -> String -> ...
