I'm a fan of the menu button as used in Android <3.0, as it was very useful for my game apps - it allowed me to take important but gameplay irrelevant functionality (saving game, reference info links) and place it somewhere where it did not clutter up the main game interface, but was still easily accessible (the options menu). This use of keys became a problem with 3.0, because it removed the MENU button and substituted it with the Action Bar. The Action bar is really not suitable for a game which likes to run full-screen, so that was a real pain. No action bar - no access to the options menu.

I am building a Angular4 project using Angular CLI (1.1.2). It runs perfectly in Chrome (Version 59.0.3071.115) and firefox(54.0.1) but when I tried to use IE11 (Verison 11.0.9600.18738) nothings shows up and when I open the develper mode in IE, it shows me the following Error: SCRIPT5022: Exception thrown and not caught File: polyfills.bundle.js, Line: 829, Column: 34 And the detailed Error message is following: Anyone knows how to solve this problem? Thanks! Switch To add more detail to @Zeqing's answer. I uncommented the following line of codes in .\my-app\src\polyfills.ts : /** IE9, IE10

How can I check if a Python object is a string (either regular or Unicode)? John Fouhy Python 2 Use isinstance(obj, basestring) for an object-to-test obj . Docs . Matt S. To check if an object o is a string type of a subclass of a string type: isinstance(o, basestring) because both str and unicode are subclasses of basestring . To check if the type of o is exactly str : type(o) is str To check if o is an instance of str or any subclass of str : isinstance(o, str) The above also work for Unicode strings if you replace str with unicode . However, you may not need to do explicit type checking at

I have just found something very weird while developing a website. While trying to get a div element to display across the top of the screen, I noticed that I wasn't achieving a desired result in any browser except for old versions of IE. In order to test some different code, instead of deleting the faulty line, I used '//' to comment it out (I'm not really even sure if that works in css) but what happened was, the compatible browsers used the uncommented code, while IE used the code marked by '//'. here is the code: #ban-menu-div{ position:fixed;top:0; //position:relative; //<-- IE keeps the

I've heard that objective-C is a proper superset of C, but is objective-C 2.0? The reason I ask is that either it isn't, or I misunderstand the phrase 'proper superset', because this code is valid C syntax: #import <stdio.h> int main () { char *nil = "hello"; printf("%s\n",nil); } But does not compile in Objective-C 2.0. Obviously, this is an easily fixable problem, but I'm writing a paper, and feel that this is something that should be pointed out. nil is not a keyword. nil is defined in objc.h [on Mac OS X] (and __DARWIN_NULL is really just NULL ): #ifndef nil #define nil __DARWIN_NULL /* id
