• Ruby Win32Api get single character non-blocking

  - by Markus Orreilly

  I'm trying to write a simple game working with two threads, one thread to get input from the user, and another thread to animate some scenes. I'm able to get characters without pressing ENTER just fine, but it blocks in the animating thread until the user presses a key. Does anyone know of a way to get a character from the keyboard non-blocking?

• # character seems to cause problems with a get Request

  - by Ankur

  I have a queryString that I pass to a servlet's doGet() method that looks like this: count=9&preId0=-99&objId0=-99&preId1=-99&objId1=-99&preId2=69&objId2=16#!78&preId3=-99&objId3=-99&preId4=-99&objId4=-99&preId5=-99&objId5=-99&preId6=-99&objId6=-99&preId7=-99&objId7=-99&preId8=-99&objId8=-99 After and including the # everything is null, so I am assuming the # has some special meaning. Is this true? and are there other such characters that will do this?

• Regular expression - starting and ending with a letter, accepting only letters, numbers and _

  - by jreid9001

  I'm trying to write a regular expression which specifies that text should start with a letter, every character should be a letter, number or underscore, there should not be 2 underscores in a row and it should end with a letter or number. At the moment, the only thing I have is ^[a-zA-Z]\w[a-zA-Z1-9_] but this doesn't seem to work properly since it only ever matches 3 characters, and allows repeated underscores. I also don't know how to specify requirements for the last character.

• What's the easiest way to assign a string returned from the server to a javascript string?

  - by powerboy

  The following does not work: var js_str= '<?php echo $str_from_server; ?>'; The problem is that, $str_from_server can contain any characters. If it contains single quotes or line breaks or others, the above code will break. And I do not have access to the server-side code. What's the easiest way to "escape" the contents of $str_from_server into a javascript string, and then it can be restored later?

• Unicode escaping in C/C++

  - by Geo

  Hi guys! I'm having a dispute with a colleague of mine. She says that the following: char* a = "\x000aaxz"; will/can be seen by the compiler as "\x000aa". I do not agree with her, as I think you can have a maximum number of 4 hex characters after the \x. Can you have more than 4 hex chars? Who is right here?

• Perl Term::ReadKey don't wait for newline

  - by tim

  In a perl script, I'm trying to accept input without blocking and without echoing the characters entered (The script is producing output and I want to have 'hotkeys' to alter its behaviour). I got as far as using use Term::ReadKey; ReadMode( "cbreak", STDIN ); if($input = ReadKey($pause_time, STDIN)){ #process input } But once the user types anything then the script stops until a newline is entered. I'd like the input to be processed per-character, without waiting for a newline.

• Signs that a SQL statement is dangerous

  - by Matt

  Hi, I want to develop a function in PHP that checks how dangerous a SQL statement is. When i say dangerous i mean, certain symbols, characters or strings that are used to get data from a database that the user shouldnt see. For example: SELECT * FROM users WHERE userId = '1' can be injected in several ways. Although i clean the params, i also want to monitor how safe the query is to run. Thanks in advance
