First, you need to open your SQLite database, which can be done as follows: SQLiteDatabase myDataBase; String mPath = dbhelper.DATABASE_PATH + dbhelper.DATABASE_NAME; myDataBase = SQLiteDatabase.openDatabase(mPath, null, SQLiteDatabase.OPEN_READWRITE); After opening the database, you can easi...

//Using Iterator Iterator iterator = deque.iterator(); while(iterator.hasNext(){ String Item = (String) iterator.next(); } //Using For Loop for(Object object : deque) { String Item = (String) object; }

Thanks to encoders and decoders, the JSR 356 offers a object oriented communication models. Messages definition Let's assume all received messages have to be transformed by the server before being sent back to all connected sessions: public abstract class AbstractMsg { public abstract void t...

public class localInner1{ private int data=30;//instance variable void display(){ class Local{ void msg(){System.out.println(data);} } Local l=new Local(); l.msg(); } public static void main(String args[]){ localInner1 obj=new localInner1(); obj.di...

The function Emitter.listenerCount(eventName) will return the number of listeners that are currently listening for the event provided as argument const EventEmitter = require("events"); class MyEmitter extends EventEmitter{} var emitter = new MyEmitter(); emitter .on("data&quot...

When a Qt event loop is used to perform operations and a non-Qt-saavy user needs to interact with that event loop, writing the slot to handle regular invocations from another thread can simplify things for other users. main.cpp: #include "OperationExecutioner.h" #include <QCoreApplic...

// Token from another example. This token is expired var tokenString = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c" token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error...

Object pollAnswered = getCurrentSession().createSQLQuery( "select * from TJ_ANSWERED_ASW where pol_id = "+pollId+" and prf_log = '"+logid+"'").uniqueResult(); with this query, you get a unique result when you know the result of the query is always going to b...

If you get a message that the browser can't connect to the server, first check to ensure the server is up. $ ps -aef | grep httpd You should see a few httpd processes if Apache is up and running.

In order to show an alert dialog containing a link which can be opened by clicking it, you can use the following code: AlertDialog.Builder builder1 = new AlertDialog.Builder(youractivity.this); builder1.setMessage(Html.fromHtml("your message,<a href=\"http://www.google.com\"&gt...

$data = $result->mysqli_fetch_array(MYSQLI_NUM);

Kernels can be compiled at runtime on the target device. To do so, you need the kernel source code the target device on which to compile a context built with the target device A quick terminology update: A program contains a collection of kernels. You can think of a program as a complete C/C...

So now we come down to the real stuff, executing your kernels on the parallel device. Please read about the hardware basics to fully understand the kernel dispatching. First you'll need to set the kernel arguments before actually calling the kernel. This is done via err = Cl.SetKernelArg(_kernel, ...

Nokogiri is somewhat like a browser, in that it will attempt to provide something useful even if the incoming HTML or XML is malformed. Unfortunately it usually does it silently, but we can ask for a list of the errors using errors: require 'nokogiri' doc = Nokogiri::XML('<node><foo/&gt...

Lets build a kernel to generate a grayscale image. We will use image data which is defined using uints for each component and with order RGBA. __constant sampler_t sampler = CLK_NORMALIZED_COORDS_FALSE | CLK_ADDRESS_CLAMP_TO_EDGE | C...

Lets walk through the most simple kernel there is and some variations of it __kernel void myKernel() { } A kernel which can be started from your main code is identified by the __kernel keyword. A Kernel function can only have return type void. __kernel void myKernel(float a, uint b, byte c) { ...

To properly work with the data each thread needs to know its position in the threadblock/global thread pool. This can be archieved with get_local_id($dim); get_global_id($dim); Those two functions return the position of the thread relative to the threadblock or all threads. get_working_dim(); ...

Lets look at a gamma correction kernel __constant sampler_t sampler = CLK_NORMALIZED_COORDS_FALSE | CLK_ADDRESS_CLAMP_TO_EDGE | CLK_FILTER_LINEAR; __kernel void Gamma(__read_only image2d_t input, __write_only image2d_t output, __c...

Dart allows to easily filter a list using where. var fruits = ['apples', 'oranges', 'bananas']; fruits.where((f) => f.startsWith('a')).toList(); //apples Of course you can use some AND or OR operators in your where clause.
