Here this will calculate the UTC time offset from current data in desired timezone. +(NSTimeInterval)getUTCOffSetIntervalWithCurrentTimeZone:(NSTimeZone *)current forDate:(NSDate *)date { NSTimeZone *utcTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"UTC"]; NSInteger currentG...

Checking whether the current date contains the symbol for AM or PM Objective-C NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setLocale:[NSLocale currentLocale]]; [formatter setDateStyle:NSDateFormatterNoStyle]; [formatter setTimeStyle:NSDateFormatterShortStyle]; NSStr...

There are many ways to return a Date from a DateTime object SELECT CONVERT(Date, GETDATE()) SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE())) returns 2016-07-21 00:00:00.000 SELECT CAST(GETDATE() AS DATE) SELECT CONVERT(CHAR(10),GETDATE(),111) SELECT FORMAT(GETDATE(), 'yyyy-MM-dd') Note th...

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...

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...

Iterator methods can be broken into two distinct groups: Adapters Adapters take an iterator and return another iterator // Iterator Adapter // | | let my_map = (1..6).map(|x| x * x); println!("{:?}", my_map); Output Map { iter: 1..6 } Note that the v...

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 ...

For functions that need to take a collection of objects, slices are usually a good choice: fn work_on_bytes(slice: &[u8]) {} Because Vec<T> and arrays [T; N] implement Deref<Target=[T]>, they can be easily coerced to a slice: let vec = Vec::new(); work_on_bytes(&vec); le...

The following output equivalent results: class IfElseExample { public string DebugToString(object a) { if (a is StringBuilder) { return DebugToStringInternal(a as StringBuilder); } else if (a is List<string>) { ...

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...

This example shows a helper class that contains methods useful, when executing the queries for data. Every method here uses Java Generic's in order to be very flexible. public <T> List<T> selectElements(AbstractDao<T, ?> dao) { if (dao == null) { return null; } ...

syncer = Queue.new a = Thread.new do syncer.pop puts "this happens at end" end b = Thread.new do puts "this happens first" STDOUT.flush syncer << :ok end [a, b].map(&:join)

To avoid infinitely blocking, reading from queues shouldn't happen on the thread merge is happening on. To avoid synchronization or infinitely waiting for one of queues while other has data, reading from queues shouldn't happen on same thread. Let's start by defining and populating two queues:...

public class SoundActivity extends Activity { private MediaPlayer mediaPlayer; ProgressBar progress_bar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tool_sound); ...

Some procedures have optional arguments. Optional arguments always come after required arguments, but the procedure can be called without them. For example, if the function, ProcedureName were to have two required arguments (argument1, argument2), and one optional argument, optArgument3, it could b...

TRACE and DEBUG log levels are there to be able to convey high detail about the operation of the given code at runtime. Setting the log level above these is usually recommended, however some care must be taken for these statements to not affect performance even when seemingly "turned off"....

Get current time: Time.now Time.new # is equivalent if used with no parameters Get specific time: Time.new(2010, 3, 10) #10 March 2010 (Midnight) Time.new(2015, 5, 3, 10, 14) #10:14 AM on 3 May 2015 Time.new(2050, "May", 3, 21, 8, 16, "+10:00") #09:08:16 PM on 3 May 2050...

Setters and Getters allow for an object to contain private variables which can be accessed and changed with restrictions. For example, public class Person { private String name; public String getName() { return name; } public void setName(String name) { i...
