Here's some sample code from one of the setups I've tried: In HomeViewController : - (void)viewDidAppear:(BOOL)animated { static BOOL

问题 Firstly I have seen the following answer https://stackoverflow.com/a/7731051/626442 and it is not quite sufficient for my needs. I have written an editor which has basic intellisense capabilities (see A New and Full Implementation of Generic Intellisense for an insight). I have implemented some basic SQL Server completion using this editor, but I keep getting intellisense popping up when I type the * key. I want to prevent this. Currently I do the following: private void TextArea_KeyDown

问题 This is a console program in Common Lisp for a Hangman type game. The first player enters a string to be guessed by the second player. My input function is below --- unfortunately the characters typed by the first player remain visible. With JavaScript it's simple, just use a password text entry box. With VB it's simple using the same sort of facility. Is there any way to do this using a native Common Lisp function? Thanks, CC. (defun get-answer () (format t "Enter the word or phrase to be

问题 How do you properly set, and then reset, the keyboard ISR in DOS? (x86 assembly, real mode, 16 bit, with TASM) I have the following assembly code which sets up my ISR for the keyboard. All it is supposed to do is print out a sentence each time a key is pressed, up to five times. Then it is supposed to exit. It seems like the ISR is being installed correctly. It will print out a sentence each time a key is pressed (once for down, once for up). However, it appears as though I am uninstalling
