You have to create a different strings.xml file for every new language. Right-click on the res folder Choose New → Values resource file Select a locale from the available qualifiers Click on the Next button (>>) Select a language Name the file strings.xml strings.xml <resources&...

Intro An array is a container object that holds a number of values. In the following image you can see an array with size 10, the first element indexed 1 and the last element 10. Autohotkey offers a few ways of defining and creating arrays. Array := [] Array := Array() Creating and initia...

myDebt := 9000 index := RegExMatch("You owe me $42", "\$(\d+)", dollars) if(index > 0) { ; indices are usually 1-based in AHK myDebt += dollars1 MsgBox, Current debt: %myDebt% } Result: Current debt: 9042

Comments in Tcl are best thought of as another command. A comment consists of a # followed by any number of characters up to the next newline. A comment can appear wherever a command can be placed. # this is a valid comment proc hello { } { # the next comment needs the ; before it to indicat...

You can use the following code for going back and forward. if (!function_exists('codepoint_encode')) { function codepoint_encode($str) { return substr(json_encode($str), 1, -1); } } if (!function_exists('codepoint_decode')) { function codepoint_decode($str) { re...

You can use the following code for going back and forward. if (!function_exists('mb_internal_encoding')) { function mb_internal_encoding($encoding = NULL) { return ($from_encoding === NULL) ? iconv_get_encoding() : iconv_set_encoding($encoding); } } if (!function_exists('mb_c...

When localizing different types of resources are required, each of which has its own home in the android project structure. Following are the different directories that we can place under the \res directory. The resource types placed in each of these directories are explained in the table below: D...

Each resource directory under the res folder (listed in the example above) can have different variations of the contained resources in similarly named directory suffixed with different qualifier-values for each configuration-type. Example of variations of `` directory with different qualifier value...

C and C++ are well known as high-performance languages - largely due to the heavy amount of code customization, allowing a user to specify performance by choice of structure. When optimizing it is important to benchmark relevant code and completely understand how the code will be used. Common opti...

The most straightforward approach to optimizing is by executing less code. This approach usually gives a fixed speed-up without changing the time complexity of the code. Even though this approach gives you a clear speedup, this will only give noticable improvements when the code is called a lot. R...

When storing JSON documents in SQL Server, We need to be able to efficiently filter and sort query results on properties of the JSON documents. CREATE TABLE JsonTable ( id int identity primary key, jsonInfo nvarchar(max), CONSTRAINT [Content should be formatted as JSON] CHECK...

Java SE 1.2 strictfp modifier is used for floating-point calculations. This modifier makes floating point variable more consistent across multiple platforms and ensure all the floating point calculations are done according to IEEE 754 standards to avoid errors of calculation (round-off errors), ov...

This worked for me to move from Ubuntu 12.04 (Jenkins ver. 1.628) to Ubuntu 16.04 (Jenkins ver. 1.651.2). I first installed Jenkins from the repositories. Stop both Jenkins servers Copy JENKINS_HOME (e.g. /var/lib/jenkins) from the old server to the new one. From a console in the new serve...

Create a new project.json and example Program.cs: dotnet new Restore needed packages: dotnet restore Compile and run the example: dotnet run

Go to the project.json directory and publish: dotnet publish It will print the output directory of the operation, enter the directory and run the published project: dotnet <project output>.dll The default folder will be: <project root>/bin/<configuration>/<target framewo...

If the program is short, you can include it in the command that runs awk: awk -F: '{print $1, $2}' /etc/passwd In this example, using command line switch -F: we advise awk to use : as input fields delimiter. Is is the same like awk 'BEGIN{FS=":"}{print $1,$2}' file Alternativelly, ...

Prolog tries alternative clauses for a predicate in the order of appearance: likes(alice, music). likes(bob, hiking). // Either alice likes music, or bob likes hiking will succeed. The disjunction (OR) operator ; can be used to express this in one rule: likes(P,Q) :- ( P = alice , Q = ...

Sometimes it is desirable to prevent Prolog from backtracking into alternative solutions. The basic tool available to the programmer to stop prolog from continuing futher in its backtrack is the cut operator. consider the following. % (percent signs mean comments) % a is the parent of b, c, and d....

ViewPropertyAnimator is a simplified and optimized way to animate properties of a View. Every single View has a ViewPropertyAnimator object available through the animate() method. You can use that to animate multiple properties at once with a simple call. Every single method of a ViewPropertyAnimat...

To bootstrap a new Erlang project, simply choose the template you want to use from the list. The available templates can be retrieved by the following command: $ rebar3 new app (built-in): Complete OTP Application structure cmake (built-in): Standalone Makefile for building C/C++ in c_src escr...
