System.IO.Compression.ZipFile.CreateFromDirectory("myfolder", "archive.zip") Create archive.zip file containing files which are in myfolder. In example paths are relative to program working directory. You can specify absolute paths.

System.IO.Compression.ZipFile.ExtractToDirectory("archive.zip", "myfolder") Extracts archive.zip to myfolder directory. In example paths are relative to program working directory. You can specify absolute paths.

' Create filestream to file Using fileStream = New IO.FileStream("archive.zip", IO.FileMode.Create) ' open zip archive from stream Using archive = New System.IO.Compression.ZipArchive(fileStream, IO.Compression.ZipArchiveMode.Create) ' create file_in_archive.txt in arch...

In Object Oriented Programming a common task is to compose objects (values). In Functional Programming it is as common task to compose values as well as functions. We are used to compose values from our experience of other programming languages using operators like +, -, *, / and so on. Value co...

Assumptions: TableView - reference to the TableView DataSource - is a class which inherits UITableViewSource DataSource.Objects - is a public List< object >(), accessible to the UIViewController private UIRefreshControl refreshControl; public override void ViewDidLoad() { base.V...

This example demonstrates POSIX Timer usage with CLOCK_REALTIME clock and SIGEV_THREAD notification method. #include <stdio.h> /* for puts() */ #include <string.h> /* for memset() */ #include <unistd.h> /* for sleep() */ #include <stdlib.h> /* for EXIT_SUCCESS */ #inc...

scrollViewDidEndDecelerating: this tells the delegate that the scroll view has ended decelerating the scrolling movement. Objective C: - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [self stoppedScrolling]; } - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView w...

Mockito provides a Matcher<T> interface along with an abstract ArgumentMatcher<T> class to verify arguments. It uses a different approach to the same use-case than the ArgumentCaptor. Additionally the ArgumentMatcher can be used in mocking too. Both use-cases make use of the Mockito.argT...

ByVal keyword before method parameter (or no keyword as ByVal is assumed by default) says that parameter will be sent in a way not allowing the method to change (assign a new value) the variable underlying the parameter. It doesn't prevent the content (or state) of the argument to be changed if it'...

The UMD (Universal Module Definition) pattern is used when our module needs to be imported by a number of different module loaders (e.g. AMD, CommonJS). The pattern itself consists of two parts: An IIFE (Immediately-Invoked Function Expression) that checks for the module loader that is being i...

Immediately invoked function expressions can be used to create a private scope while producing a public API. var Module = (function() { var privateData = 1; return { getPrivateData: function() { return privateData; } }; })(); Module.getPrivateData(); // 1 Module.priva...

Add the gradle dependency in app-level build.gradle compile 'com.android.volley:volley:1.0.0' Also, add the android.permission.INTERNET permission to your app's manifest. **Create Volley RequestQueue instance singleton in your Application ** public class InitApplication extends Application { ...

Audio stream types There are different profiles of ringtone streams. Each one of them has it's different volume. Every example here is written for AudioManager.STREAM_RING stream type. However this is not the only one. The available stream types are: STREAM_ALARM STREAM_DTMF STREAM_MUSIC STR...

An example of "before" middleware would be as follows: <?php namespace App\Http\Middleware; use Closure; class BeforeMiddleware { public function handle($request, Closure $next) { // Perform action return $next($request); } } while &quot...

If you want to remove calls to certain methods, assuming they return void and have no side affects (as in, calling them doesn't change any system values, reference arguments, statics, etc.) then you can have ProGuard remove them from the output after the build is complete. For example, I find this ...

template <div id="demo">{{fullName}}</div> watch example var vm = new Vue({ el: '#demo', data: { firstName: 'Foo', lastName: 'Bar', fullName: 'Foo Bar' } }) vm.$watch('firstName', function (val) { this.fullName = val + ' ' + this.lastName })...

This example portrays the most simple ALV creation using the cl_salv_table class and no additional formatting options. Additional formatting options would be included after the TRY ENDTRY block and before the alv->display( ) method call. All subsequent examples using the ABAP Objects approach to...

This example shows how to optimize the column width so that column headings and data are not chopped off. alv->get_columns( )->set_optimize( ).

This example hides the MANDT (client) field from the ALV. Note that the parameter passed to get_column( ) must be capitalized in order for this to work. alv->get_columns( )->get_column( 'MANDT' )->set_visible( if_salv_c_bool_sap=>false ).

The column text may change upon the horizontal resizing of a column. There are three methods to accomplish this: Method NameMaximum Length of Headingset_short_text10set_medium_text20set_long_text40 The following example shows usage of all three. A column object is declared and instantiated as a re...
