Programs & Examples On #Econnect

I had the same issue with Xcode 11.6 and iOS 13.6. Unpairing the device and adding it again solved the problem.

Starting with MySQL 8.0.4, they have changed the default authentication plugin for MySQL server from mysql_native_password to caching_sha2_password.

You can run the below command to resolve the issue.

sample username / password => student / pass123

ALTER USER 'student'@'localhost' IDENTIFIED WITH mysql_native_password BY 'pass123';

Refer the official page for details: MySQL Reference Manual

For existing mysql 8.0 installs on Windows 10 mysql,

1. launch installer,

2. click "Reconfigure" under QuickAction (to the left of MySQL Server), then

3. click next to advance through the next 2 screens until arriving

4. at "Authentication Method", select "Use Legacy Authentication Method (Retain MySQL 5.x compatibility"

5. Keep clicking until install is complete

The following code worked for me:

echo userInput

This error may be also related to the fact that you have an error in your "spring.datasource.url" when you gave a wrong db name for example

My issue was that I went through my AndroidManifest.xml file and had removed the line

<uses-permission android:name="android.permission.INTERNET" />

because my app will not need internet. However, the react native debugging app does need internet access (to access the packager) Whoops. :)

The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.

Please see the error below:

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

which points to username not getting populated.

Please recheck system properties

dataSource.setUsername(System.getProperty("root"));

some packages seems to be missing as well pointing to a dependency issue:

package org.gjt.mm.mysql does not exist

Please run a mvn dependency:tree command to check for dependencies

You don't need hibernate-entitymanager-xxx.jar, because of you use a Hibernate session approach (not JPA). You need to close the SessionFactory too and rollback a transaction on errors. But, the problem, of course, is not with those.

This is returned by a database

#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"
#

Looks like you've provided an incorrect username or (and) password.

in my case just

const myReducers = combineReducers({
  user: UserReducer
});

const store: any = createStore(
  myReducers,
  applyMiddleware(thunk)
);

shallow(<Login />, { context: { store } });

I have used MySQL DB for Hive MetaStore. Please follow the below steps:

• in hive-site.xml the metastore should be proper

<property>
 <name>javax.jdo.option.ConnectionURL</name> 
 <value>jdbc:mysql://localhost/metastorecreateDatabaseIfNotExist=true&amp;useSSL=false</value>
</property>

• go to the mysql: mysql -u hduser -p
• then run drop database metastore
• then come out from MySQL and execute schematool -initSchema dbType mysql

Now error will go.

Same thing happend to me after upgrading distro.

Running sudo apt-get install php7.0-mysql fixed it for me.

the following points work for me. Try:

1. start SSMS as administrator
2. make sure SQL services are running. Change startup type to 'Automatic'

3. In SSMS, in service instance property table, enable below:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile fileTree(include: 'Parse-*.jar', dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.android.support:cardview-v7:23.2.0'
    compile 'com.android.support:design:24.0.0-alpha1'
    compile "com.google.firebase:firebase-invites:9.2.0"
    compile "com.google.firebase:firebase-ads:9.2.0"
    compile 'com.google.firebase:firebase-database:9.2.0'
    compile 'com.google.firebase:firebase-core:9.2.0'
}

I add the com.google.firebase:firebase-core:9.2.0 line and choose the same version (9.2.0) for all firebase libraries and the issue was solved.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

I had the same its because of version incompatibility check for version or remove version if using spring boot

I took a similar approach as Sean3z but instead I have the connection closed everytime i make a query.

His way works if it's only executed on the entry point of your app, but let's say you have controllers that you want to do a var db = require('./db'). You can't because otherwise everytime you access that controller you will be creating a new connection.

To avoid that, i think it's safer, in my opinion, to open and close the connection everytime.

here is a snippet of my code.

mysq_query.js

// Dependencies
var mysql   = require('mysql'),
    config  = require("../config");

/*
 * @sqlConnection
 * Creates the connection, makes the query and close it to avoid concurrency conflicts.
 */
var sqlConnection = function sqlConnection(sql, values, next) {

    // It means that the values hasnt been passed
    if (arguments.length === 2) {
        next = values;
        values = null;
    }

    var connection = mysql.createConnection(config.db);
    connection.connect(function(err) {
        if (err !== null) {
            console.log("[MYSQL] Error connecting to mysql:" + err+'\n');
        }
    });

    connection.query(sql, values, function(err) {

        connection.end(); // close the connection

        if (err) {
            throw err;
        }

        // Execute the callback
        next.apply(this, arguments);
    });
}

module.exports = sqlConnection;

Than you can use it anywhere just doing like

var mysql_query = require('path/to/your/mysql_query');
mysql_query('SELECT * from your_table where ?', {id: '1'}, function(err, rows)   {
    console.log(rows);
});

UPDATED: config.json looks like

{
        "db": {
        "user"     : "USERNAME",
        "password" : "PASSWORD",
        "database" : "DATABASE_NAME",
        "socketPath": "/tmp/mysql.sock"
    }
}

Hope this helps.

We're using symfony with doctrine and we are in the process of automating deployment. I got this error when I simply hadn't provided the correct db creds in parameters.yml (I was running doctrine:migrations:migrate)

This thread has sent me on a bit of a wild goose chase, so I'm leaving this here so others might not have to.

AndroidStudio:

Go to: Tools -> Android -> Android Device Monitor

see the Device tab, under many icons, last one is drop-down arrow.

Open it.

At the bottom: RESET ADB.

It could be that the gradle-2.1 distribution specified by the wrapper was not downloaded properly. This was the root cause of the same problem in my environment.

Look into this directory:

ls -l ~/.gradle/wrapper/dists/

In there you should find a gradle-2.1 folder. Delete it like so:

rm -rf ~/.gradle/wrapper/dists/gradle-2.1-bin/

Restart IntelliJ, after that it will restart the download from the beginning and hopefully work.

Thanks, Ioannis

I had the same issue.

Make sure that In SQL Server configuration --> SQL Server Services --> SQL Server Agent is enable

This solved my problem

Please download the correct version of Oracle Client like Oracle Client 11.2 32-Bit; which resolved the problem for me.

I deleted the ojdbc14.jar file and used ojdbc6.jar instead and it worked for me

In my case, with letsencrypt https, this was caused by using cert.pem instead of fullchain.pem as the certificate file on the requested server. See this thread for details.

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

I have similar problem. Spring 4 and Tomcat 8. I solve the problem with Spring configuration

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">
    <property name="initialSize" value="10" />
    <property name="maxActive" value="25" />
    <property name="maxIdle" value="20" />
    <property name="minIdle" value="10" />
     ...
    <property name="testOnBorrow" value="true" />
    <property name="validationQuery" value="SELECT 1" />
 </bean>

I have tested. It works well! This two line does everything in order to reconnect to database:

<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1" />

add persist security info=True; in connection string.

When you encounter exceptions like this, the most useful information is generally at the bottom of the stacktrace:

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
  at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
  ...
  at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:246)

The problem is that Tomcat can't find com.mysql.jdbc.Driver. This is usually caused by the JAR containing the MySQL driver not being where Tomcat expects to find it (namely in the webapps/<yourwebapp>/WEB-INF/lib directory).

I was having the same problem in an application that I was maintaining, among all the adjustments to prepare the environment, I also spent almost an hour banging my head with this error "ORA-01036: illegal variable name / number" until I found out that the application connection was pointed to an outdated database, so the application passed two more parameters to the outdated database procedure causing the error.

There is an easy solution by using java FunctionalInterface and then add that interface as dependency for the class you are trying to unit test.

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.

seems fairly clear-cut: your OS can't find enough RAM to start a new Java process, which is in this case the Gradle builder. Perhaps you don't have enough RAM, or not enough swap, or you have too many other memory-hungry processes running at the same time.

I fixed this problem with sql command line:

connect system/<password>
alter system set processes=300 scope=spfile;
alter system set sessions=300 scope=spfile;

Restart database.

I had the same problem - for me it was the SQL Server running out of memory. Freeing up some memory solved the issue

run the below command in command prompt

tnsping Datasource

This should give a response like below

git remote prune and git fetch --prune do the same thing: deleting the refs to the branches that don't exist on the remote, as you said. The second command connects to the remote and fetches its current branches before pruning.

However it doesn't touch the local branches you have checked out, that you can simply delete with

git branch -d  random_branch_I_want_deleted

Replace -d by -D if the branch is not merged elsewhere

git prune does something different, it purges unreachable objects, those commits that aren't reachable in any branch or tag, and thus not needed anymore.

Another potential cause, for other people coming across the same error message is that this error will occur if you are accessing a table in a different schema from the one you have authenticated with.

In this case you would need to add the schema name to your entity entry:

@Table(name= "catalog", schema = "targetSchemaName")

this might help someone who had similar issue like me , i followed all naming and interface standards., But i was still facing issue.

My param name was -->  update_datetime 

I wanted to fetch my entities based on the update_datetime in the descending order, and i was getting the error

org.springframework.data.mapping.PropertyReferenceException: No property update found for type Release!

Somehow it was not reading the Underscore character --> ( _ )

so for workaround i changed the property name as  --> updateDatetime 

and then used the same for using JpaRepository methods.

It Worked !

As an alternative approach, Mongoose does export a constructor for a new instance on the default instance. So something like this is possible.

var Mongoose = require('mongoose').Mongoose;

var instance1 = new Mongoose();
instance1.connect('foo');

var instance2 = new Mongoose();
instance2.connect('bar');

This is very useful when working with separate data sources, and also when you want to have a separate database context for each user or request. You will need to be careful, as it is possible to create a LOT of connections when doing this. Make sure to call disconnect() when instances are not needed, and also to limit the pool size created by each instance.

Based on previous answers. I resolved my issue by removing global variable at package level to procedure, since there was no impact in my case.

Original script was

create or replace PACKAGE BODY APPLICATION_VALIDATION AS 

V_ERROR_NAME varchar2(200) := '';

PROCEDURE  APP_ERROR_X47_VALIDATION (   PROCESS_ID IN VARCHAR2 ) AS BEGIN
     ------ rules for validation... END APP_ERROR_X47_VALIDATION ;

/* Some more code
*/

END APPLICATION_VALIDATION; /

Rewritten the same without global variable V_ERROR_NAME and moved to procedure under package level as

Modified Code

create or replace PACKAGE BODY APPLICATION_VALIDATION AS

PROCEDURE  APP_ERROR_X47_VALIDATION (   PROCESS_ID IN VARCHAR2 ) AS

**V_ERROR_NAME varchar2(200) := '';** 

BEGIN
     ------ rules for validation... END APP_ERROR_X47_VALIDATION ;

/* Some more code
*/

END APPLICATION_VALIDATION; /

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

For all people ending here because of a codebase with a mix of Typegoose and Mongoose :

Create a db connection for each one :

Mongoose :

module.exports = db_mongoose.model("Car", CarSchema);

Typegoose :

db_typegoose.model("Car", CarModel.schema, "cars");

I had the same Gradle build problems in Eclipse and by doing the following steps, the problems were solved:

• set up project to use correct java version of java project properties-> java build path -> jre system (edit the current one, and add the correct java jdk or jre there)

• window->Preferences ->Gradle->Arguments-> Workspace JRE (set to the correct one)

Hope this will help those who have the same problems.

I ran into this problem and fixed it by closing the input and output streams before closing the socket. Now I can disconnect and connect again with no issues.

https://stackoverflow.com/a/3039807/5688612

In Kotlin:

fun disconnect() {
    bluetoothSocket.inputStream.close()
    bluetoothSocket.outputStream.close()
    bluetoothSocket.close()
}

The issue could be that the VM is connected to the network via NAT. You need to set the network adapter of the VM to a bridged connection so that the VM will get it's own IP within the actual network and not on the LAN on the host.

I just fixed it by restarting / starting oracleService in services

This topic is old but if other people like me search a solution, this is a solution that I have found:

Public Function DBStats() As Boolean
    On Error GoTo errorHandler
        If Not IsNull(myBase.Version) Then 
            DBStats = True
        End If
        Exit Function
    errorHandler:
        DBStats = False  
End Function

So "myBase" is a Database Object, I have made a class to access to database (class with insert, update etc...) and on the module the class is use declare in an object (obviously) and I can test the connection with "[the Object].DBStats":

Dim BaseAccess As New myClass
BaseAccess.DBOpen 'I open connection
Debug.Print BaseAccess.DBStats ' I test and that tell me true
BaseAccess.DBClose ' I close the connection
Debug.Print BaseAccess.DBStats ' I test and tell me false

Edit : In DBOpen I use "OpenDatabase" and in DBClose I use ".Close" and "set myBase = nothing" Edit 2: In the function, if you are not connect, .version give you an error so if aren't connect, the errorHandler give you false

If you use ASP.NET and IISExpress go to "C:\Users\\Documents\IISExpress\config\applicationhost.config", search for your Project and look if you have a faulty virtualDirectory entry.

In Android Studio 3 and above You Can See a "Device File Explorer" Section in Right-Bottom Side of Android Studio.

Open it, Then You Can See The File Tree, You Can Find an Application Databases In this Path:

/data/data/{package_name}/databases/

For Maven based projects you need a dependency.

<dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.38</version>
</dependency>

First of all, you need to check that the IIS is installed in your machine, for that you can go to:

Control Panel --> Add or Remove Programs --> Windows Features --> And Check if Internet Information Services is installed with at least the 'Web Administration Tools' Enabled and The 'World Wide Web Service'

If not, check it, and Press Accept to install it.

Once that is done, you need to go to Administrative Tools in Control Panel and the IIS Will be there. Or simply run inetmgr (after Win+R).

Edit: You should have something like this:

Try to add the path to tnsnames.ora to the config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <oracle.manageddataaccess.client>
    <version number="4.112.3.60">
      <settings>
        <setting name="TNS_ADMIN" value="C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN\" />
      </settings>
    </version>
  </oracle.manageddataaccess.client>
</configuration>

Try:

SqlConnection myConnection = new SqlConnection("Database=testDB;Server=Paul-PC\\SQLEXPRESS;Integrated Security=True;connect timeout = 30");

In runtime problems like these firstly open logcat if you are using android studio, try to analyse trace tree, go to the beginning from where exception started to rise, since that is usually the source of the problem. Now check for two things:

1. Check in device file explorer(on the bottom right) there exist a database created by you. mostly you find it in DATA -> DATA -> com.example.hpc.demo(your pakage name) -> DATABASE -> demo.db

2. Check that in your helper class you have added required '/' for example like below
   DB_location = "data/data/" + mcontext.getPackageName() + "/database/";

You could try changing the: SizeMode property of the PictureBox.

You could also set your image as the BackGroundImage of the PictureBox and try changing the BackGroundImageLayout to the correct mode.

Not exactly what OP was asking, but... it's ridiculously easy to do that with urllib:

from urllib.request import urlretrieve
url = 'http://mirror.pnl.gov/releases/16.04.2/ubuntu-16.04.2-desktop-amd64.iso'
dst = 'ubuntu-16.04.2-desktop-amd64.iso'
urlretrieve(url, dst)

Or this way, if you want to save it to a temporary file:

from urllib.request import urlopen
from shutil import copyfileobj
from tempfile import NamedTemporaryFile
url = 'http://mirror.pnl.gov/releases/16.04.2/ubuntu-16.04.2-desktop-amd64.iso'
with urlopen(url) as fsrc, NamedTemporaryFile(delete=False) as fdst:
    copyfileobj(fsrc, fdst)

I watched the process:

watch 'ps -p 18647 -o pid,ppid,pmem,rsz,vsz,comm,args; ls -al *.iso'

And I saw the file growing, but memory usage stayed at 17 MB. Am I missing something?

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

If you've tried modifying etc/hosts and adding java.rmi.server.hostname property as well but still registry is being bind to 127.0.0.1

the issue for me was resolved after explicitly setting System property through code though the same property wasn't picked from jvm args

Try the following suggestions:

1. Your machine may have a static IP; map this IP to the hosts file as localhost.
2. Try to log in from your computer or within the network via mysql command; if login is successful, it means that MySQL runs fine.

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

this how you reset the enitityManager in Symfony3. It should reopen the em if it has been closed:

In a Controller:

$em = $this->getDoctrine()->resetEntityManager();

In a service:

  if (!$this->em->isOpen()) {
        $this->managerRegistry->resetManager('managername');
        $this->em = $this->managerRegistry->getManager('default');
    }

    $this->em->persist(...);

Don't forget to inject the '@doctrine' as a service argument in service.yml!

I'm wondering, if this problem happens if different methodes concurrently tries to access the same entity at the same time?

team! For execute SQL-query from your Servlet you should add JDBC jar library in folder

WEB-INF/lib

After this you could call driver, example :

Class.forName("oracle.jdbc.OracleDriver");

Now Y can use connection to DB-server

==> 73!

I also ran into this problem last week and have managed to fix this now. I got the idea to resolve this one from the response shared by @gukoff.

My requirement and situation was slightly different from the ones shared so far but the issue was fundamentally the same so I thought of sharing it on this thread.

I was actually trying to query zookeeper quorum (after every 30 seconds) for some information from my application and was using the Curator Framework for this purpose (the methods available in LeaderLatch class). So, essentially I was starting up a CuratorFramework client and supplying this to LeaderLatch object.

Only after I ran into the error mentioned in this thread - I realised that I did not close the zookeeper client connection(s) established in my applications. The maxClientCnxns property had the value of 60 and as soon as the number of connections (all of them were stale connections) touched 60, my application started complaining with this error.

I found out about the number of open connections by:

1. Checking the zookeeper logs, where there were warning messages stating "Too many connections from {IP address of the host}"

2. Running the following netstat command from the same host mentioned in the above logs where my application was running:

netstat -no | grep :2181 | wc -l

Note: The 2181 port is the default for zookeeper supplied as a parameter in grep to match the zookeeper connections.

To fix this, I cleared up all of those stale connections manually and then added the code for closing the zookeeper client connections gracefully in my application.

I hope this helps!

I had also similar problem. In my case brokerUrl was not configured properly. So that's way I received following Error:

Cause: Error While attempting to add new Connection to the pool: nested exception is javax.jms.JMSException: Could not connect to broker URL : tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused

& I resolved it following way.

   ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();

  connectionFactory.setBrokerURL("tcp://hostname:61616");
  connectionFactory.setUserName("admin");
  connectionFactory.setPassword("admin");

First off you need to download and install ODP from this site http://www.oracle.com/technetwork/topics/dotnet/index-085163.html

After installation add a reference of the assembly Oracle.DataAccess.dll.

Your are good to go after this.

using System; 
using Oracle.DataAccess.Client; 

class OraTest
{ 
    OracleConnection con; 
    void Connect() 
    { 
        con = new OracleConnection(); 
        con.ConnectionString = "User Id=<username>;Password=<password>;Data Source=<datasource>"; 
        con.Open(); 
        Console.WriteLine("Connected to Oracle" + con.ServerVersion); 
    }

    void Close() 
    {
        con.Close(); 
        con.Dispose(); 
    } 

    static void Main() 
    { 
        OraTest ot= new OraTest(); 
        ot.Connect(); 
        ot.Close(); 
    } 
}

Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)

Once you've generated your JSON, you can use something like the code below to POST it

StringRequestEntity requestEntity = new StringRequestEntity(
    JSON_STRING,
    "application/json",
    "UTF-8");

PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);

int statusCode = httpClient.executeMethod(postMethod);

Edit

Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:

StringEntity requestEntity = new StringEntity(
    JSON_STRING,
    ContentType.APPLICATION_JSON);

HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);

HttpResponse rawResponse = httpclient.execute(postMethod);

I was hitting the same issue. Added mysql service port number(3307), resolved the issue.

conn = DriverManager.getConnection("jdbc:mysql://localhost:3307/?" + "user=root&password=password");

To be concise and precise download the compatible jdbc (.jar) file compatible with your MySql version and put it in lib folder. For example for MySQL 8.0.2 download Connector/J 8.0.20

The problem could also come because of a lack of SQL driver in your Tomcat installation directory.

I had to had mysql-connector-java-5.1.23-bin.jar in apache-tomcat-9.0.12/lib/ folder.

https://dev.mysql.com/downloads/connector/j/

I had this error too, my problem was in some part of code I didn't close file descriptor and in other part, I tried to open that file!! use close(fd) system call after you finished working on a file.

string strConn = "Data Source=ORCL134; User ID=user; Password=psd;";

System.Data.OracleClient.OracleConnection con = newSystem.Data.OracleClient.OracleConnection(strConn);
    con.Open();

    System.Data.OracleClient.OracleCommand Cmd = 
        new System.Data.OracleClient.OracleCommand(
            "SELECT * FROM TBLE_Name WHERE ColumnName_year= :year", con);

//for oracle..it is :object_name and for sql it s @object_name
    Cmd.Parameters.Add(new System.Data.OracleClient.OracleParameter("year", (txtFinYear.Text).ToString()));

    System.Data.OracleClient.OracleDataAdapter da = new System.Data.OracleClient.OracleDataAdapter(Cmd);
    DataSet myDS = new DataSet();
    da.Fill(myDS);
    try
    {
        lblBatch.Text = "Batch Number is : " + Convert.ToString(myDS.Tables[0].Rows[0][19]);
        lblBatch.ForeColor = System.Drawing.Color.Green;
        lblBatch.Visible = true;
    }
    catch 
    {
        lblBatch.Text = "No Data Found for the Year : " + txtFinYear.Text;
        lblBatch.ForeColor = System.Drawing.Color.Red;
        lblBatch.Visible = true;   
    }
    da.Dispose();
    con.Close();

I think you should check sending your messages using the fan-out exchanger. That way you willl receiving the same message for differents consumers, under the table RabbitMQ is creating differents queues for each one of this new consumers/subscribers.

This is the link for see the tutorial example in javascript https://www.rabbitmq.com/tutorials/tutorial-one-javascript.html

then drag this class to you jframe,and it's done

it's deprecated,but it works.........

A couple things could be happening here;

• Your INSERT is running long, and client is disconnecting. When it reconnects it's not selecting a database, hence the error. One option here is to run your batch file from the command line, and select the database in the arguments, like so;

$ mysql db_name < source.sql

• Another is to run your command via php or some other language. After each long - running statement, you can close and re-open the connection, ensuring that you're connected at the start of each query.

If your using eclipse with tomcat follow the below steps

1. On server window Double click on tomcat, It will open the tomcat's Overview window .

2. In the Overview window you will find Open launch configuration under General information and click on Open launch configuration.

3. In the edit Configuration window look for Arguments and click on It.
4. In the arguments tag look for VM arguments.
5. simply paste this -Xms256m -Xmx512m -XX:PermSize=256m -XX:MaxPermSize=512m to the end of the arguments.

By reading your exception , It's sure that you forgot to autowire customerService

You should autowire your customerservice .

make following changes in your controller class

@Controller
public class CustomerController{

    @Autowired
    private Customerservice customerservice;
......other code......

}

Again your service implementation class

write

@Service
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerDAO customerDAO;
......other code......

.....add transactional methods
}

If you are using hibernate make necessary changes in your applicationcontext xml file(configuration of session factory is needed).

you should autowire sessionFactory set method in your DAO mplementation

    // ... set up config here
    var methodTester = new Mock<Transfer>(configInfo);
    methodTester.CallBase = true;

        .Throws<System.IO.IOException>();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.

I had a similar problem with HttpClient version 4.

I couldn't connect to the server because of a SOCKS proxy error and I fixed it using the below configuration:

client.getParams().setParameter("socksProxyHost",proxyHost);
client.getParams().setParameter("socksProxyPort",proxyPort);

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

I was also facing the error "Error preloading the connection pool" while using Oracle 10g Express Edition with my Spring and CAS based application during login.

My CAS based application only has classes12.jar in its classpath, Placing ojdbc14.jar in the classpath has resolved my problem.

You need to use ?param instead of @param when performing queries to MySQL

 str_carSql = "insert into members_car (car_id, member_id, model, color, chassis_id, plate_number, code) values (?id,?m_id,?model,?color,?ch_id,?pt_num,?code)"
        sqlCommand.Connection = SQLConnection
        sqlCommand.CommandText = str_carSql
        sqlCommand.Parameters.AddWithValue("?id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?m_id", TextBox20.Text)
        sqlCommand.Parameters.AddWithValue("?model", TextBox23.Text)
        sqlCommand.Parameters.AddWithValue("?color", TextBox24.Text)
        sqlCommand.Parameters.AddWithValue("?ch_id", TextBox22.Text)
        sqlCommand.Parameters.AddWithValue("?pt_num", TextBox21.Text)
        sqlCommand.Parameters.AddWithValue("?code", ComboBox1.SelectedItem)
        sqlCommand.ExecuteNonQuery()

Change the catch block to see the actual exception:

  Catch ex As Exception
         MsgBox(ex.Message)   
          Return False

    End Try

By Default the InternetExplorerDriver listens on port "5555". Change your huburl to match that. you can look on the cmd box window to confirm.

I prefer to stop the MongoDB server using the port command itself.

sudo port unload mongodb

And to start it again.

sudo port load mongodb

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

Setting the identity only makes this work in my pages.

If you don't want use connection pool (you sure, that your app has only one connection), you can do this - if connection falls you must establish new one - call method .openSession() instead .getCurrentSession()

For example:

SessionFactory sf = null;
// get session factory
// ...
//
Session session = null;
try {
        session = sessionFactory.getCurrentSession();
} catch (HibernateException ex) {
        session = sessionFactory.openSession();
}

If you use Mysql, you can set autoReconnect property:

    <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1/database?autoReconnect=true</property>

I hope this helps.

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

I go with

HttpContext.Current.Request.ServerVariables["HTTP_HOST"]

In my case I was getting this error running my app in wildfly with the .ear deployed from eclipse. Because it was deployed from eclipse, the deployment folder did not contain an .ear file, but a folder representing it, and inside of it all the jars that would have been contained in the .ear file; like if the ear was unzipped.

So I had in on jar:

class MySuperClass {
  protected void mySuperMethod {}
}

And in another jar:

class MyExtendingClass extends MySuperClass {

  class MyChildrenClass {
    public void doSomething{
      mySuperMethod();
    }
  }
}

The solution for this was adding a new method to MyExtendingClass:

class MyExtendingClass extends MySuperClass {

  class MyChildrenClass {
    public void doSomething{
      mySuperMethod();
    }
  }

  @Override
  protected void mySuperMethod() {
    super.mySuperMethod();
  }
}

You're right in your assumption about Spring vs. Quartz instantiating the class. However, Spring provides some classes that let you do some primitive dependency injection in Quartz. Check out SchedulerFactoryBean.setJobFactory() along with the SpringBeanJobFactory. Essentially, by using the SpringBeanJobFactory, you enable dependency injection on all Job properties, but only for values that are in the Quartz scheduler context or the job data map. I don't know what all DI styles it supports (constructor, annotation, setter...) but I do know it supports setter injection.

I found the solution

since MySQL need the Localhost in-order to work.

go to /etc/network/interfaces file and make sure you have the localhost configuration set there:

auto lo
iface lo inet loopback

NOW RESTART the Networking subsystem and the MySQL Services:

sudo /etc/init.d/networking restart

sudo /etc/init.d/mysql restart

Try it now

It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.

check that you entered a variable as argument with the '$' symbol

I suspect that the line

DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));

is causing the problem. Is it possible that the op_Id value is being set to null by the stored procedure?

To Guard against it use the Convert.IsDBNull method. For example:

if (!Convert.IsDBNull(dataAccCom.GetParameterValue(IDbCmd, "op_Id"))
{
 DataTO.Id = Convert.ToInt64(dataAccCom.GetParameterValue(IDbCmd, "op_Id"));
}
else 
{
 DataTO.Id = ...some default value or perform some error case management
}

For those finding this via Google;
I was getting this error because, as suggested by the error, I failed to close a SqlDataReader prior to creating another on the same SqlCommand, mistakenly assuming that it would be garbage collected when leaving the method it was created in.

I solved the issue by calling sqlDataReader.Close(); before creating the second reader.

First make sure that the folder in which your .mdf file resides is not read only. If it is, un-check that option and make sure it reflects to folders and files within that folder.

Once that is done, Open Management Studio, in the Object Explorer right click on the Database which is read only and select Properties. In the Options Menu, check that the Read-Only property is false.

You can try like below with sqljdbc4-2.0.jar:

 public void getConnection() throws ClassNotFoundException, SQLException, IllegalAccessException, InstantiationException {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
        String url = "jdbc:sqlserver://<SERVER_IP>:<PORT_NO>;databaseName=" + DATABASE_NAME;
        Connection conn = DriverManager.getConnection(url, USERNAME, PASSWORD);
        System.out.println("DB Connection started");
        Statement sta = conn.createStatement();
        String Sql = "select * from TABLE_NAME";
        ResultSet rs = sta.executeQuery(Sql);
        while (rs.next()) {
            System.out.println(rs.getString("COLUMN_NAME"));
        }
    }

The solution is straightforward.

Make sure that the database connector can be reached by your classpath when running (not compiling) the program, e.g.:

java -classpath .;c:\path\to\mysql-connector-java-5.1.39.jar YourMainClass 

Also, if you're using an old version of Java (pre JDBC 4.0), before you do DriverManager.getConnection this line is required:

Class.forName("your.jdbc.driver.TheDriver"); // this line is not needed for modern Java

I've had similar situation and my problem was related to Active Directory and sitting behind vpn.

Found this gold after working like that for half a year: http://bjg.io/guide/cygwin-ad/

All you basicaly need is to disable db in /etc/nsswitch.conf (you can find it in your git directory) from passwd and group section, so the file looks like:

# Begin /etc/nsswitch.conf
passwd: files
group: files
db_enum: cache builtin
db_home: cygwin desc
db_shell: cygwin desc
db_gecos: cygwin desc
# End /etc/nsswitch.conf

and then update your local password and group settings once:

$ mkpasswd -l -c > /etc/passwd
$ mkgroup -l -c > /etc/group

Note: You don't need to check if your service is running, CheckIfServiceIsRunning(), because bindService() will start it if it isn't running.

Also: if you rotate the phone you don't want it to bindService() again, because onCreate() will be called again. Be sure to define onConfigurationChanged() to prevent this.

Connect to mysql

Here are a few points:

• You could consider upgrading to HttpClient 4 (generally speaking, if you can, I don't think version 3 is still actively supported).

• A 500 status code is a server error, so it might be useful to see what the server says (any clue in the response body you're printing?). Although it might be caused by your client, the server shouldn't fail this way (a 4xx error code would be more appropriate if the request is incorrect).

• I think setDoAuthentication(true) is the default (not sure). What could be useful to try is pre-emptive authentication works better:

  client.getParams().setAuthenticationPreemptive(true);
  

Otherwise, the main difference between curl -d "" and what you're doing in Java is that, in addition to Content-Length: 0, curl also sends Content-Type: application/x-www-form-urlencoded. Note that in terms of design, you should probably send an entity with your POST request anyway.

I restarted SQL Server (Sharepoint) service and it solved the issue.

I would highly recommend the REST client Retrofit.

I have found this well written blog post extremely helpful, it also contains simple example code. The author uses Retrofit to make the network calls and Otto to implement a data bus pattern:

http://www.mdswanson.com/blog/2014/04/07/durable-android-rest-clients.html

The window.navigator.onLine attribute and its associated events are currently unreliable on certain web browsers (especially Firefox desktop) as @Junto said, so I wrote a little function (using jQuery) that periodically checks the network connectivity status and raise the appropriate offline and online events:

// Global variable somewhere in your app to replicate the 
// window.navigator.onLine variable (this last is not modifiable). It prevents
// the offline and online events to be triggered if the network
// connectivity is not changed
var IS_ONLINE = true;

function checkNetwork() {
  $.ajax({
    // Empty file in the root of your public vhost
    url: '/networkcheck.txt',
    // We don't need to fetch the content (I think this can lower
    // the server's resources needed to send the HTTP response a bit)
    type: 'HEAD',
    cache: false, // Needed for HEAD HTTP requests
    timeout: 2000, // 2 seconds
    success: function() {
      if (!IS_ONLINE) { // If we were offline
        IS_ONLINE = true; // We are now online
        $(window).trigger('online'); // Raise the online event
      }
    },
    error: function(jqXHR) {
      if (jqXHR.status == 0 && IS_ONLINE) {
        // We were online and there is no more network connection
        IS_ONLINE = false; // We are now offline
        $(window).trigger('offline'); // Raise the offline event
      } else if (jqXHR.status != 0 && !IS_ONLINE) {
        // All other errors (404, 500, etc) means that the server responded,
        // which means that there are network connectivity
        IS_ONLINE = true; // We are now online
        $(window).trigger('online'); // Raise the online event
      }
    }
  });
}

You can use it like this:

// Hack to use the checkNetwork() function only on Firefox 
// (http://stackoverflow.com/questions/5698810/detect-firefox-browser-with-jquery/9238538#9238538)
// (But it may be too restrictive regarding other browser
// who does not properly support online / offline events)
if (!(window.mozInnerScreenX == null)) {
    window.setInterval(checkNetwork, 30000); // Check the network every 30 seconds
}

To listen to the offline and online events (with the help of jQuery):

$(window).bind('online offline', function(e) {
  if (!IS_ONLINE || !window.navigator.onLine) {
    alert('We have a situation here');
  } else {
    alert('Battlestation connected');
  }
});

I had to set the value in '' and ""

Each method of mysqli can fail. You should test each return value. If one fails, think about whether it makes sense to continue with an object that is not in the state you expect it to be. (Potentially not in a "safe" state, but I think that's not an issue here.)

Since only the error message for the last operation is stored per connection/statement you might lose information about what caused the error if you continue after something went wrong. You might want to use that information to let the script decide whether to try again (only a temporary issue), change something or to bail out completely (and report a bug). And it makes debugging a lot easier.

$stmt = $mysqli->prepare("INSERT INTO testtable VALUES (?,?,?)");
// prepare() can fail because of syntax errors, missing privileges, ....
if ( false===$stmt ) {
  // and since all the following operations need a valid/ready statement object
  // it doesn't make sense to go on
  // you might want to use a more sophisticated mechanism than die()
  // but's it's only an example
  die('prepare() failed: ' . htmlspecialchars($mysqli->error));
}

$rc = $stmt->bind_param('iii', $x, $y, $z);
// bind_param() can fail because the number of parameter doesn't match the placeholders in the statement
// or there's a type conflict(?), or ....
if ( false===$rc ) {
  // again execute() is useless if you can't bind the parameters. Bail out somehow.
  die('bind_param() failed: ' . htmlspecialchars($stmt->error));
}

$rc = $stmt->execute();
// execute() can fail for various reasons. And may it be as stupid as someone tripping over the network cable
// 2006 "server gone away" is always an option
if ( false===$rc ) {
  die('execute() failed: ' . htmlspecialchars($stmt->error));
}

$stmt->close();

Just a few notes six years later...

The mysqli extension is perfectly capable of reporting operations that result in an (mysqli) error code other than 0 via exceptions, see mysqli_driver::$report_mode.
die() is really, really crude and I wouldn't use it even for examples like this one anymore.
So please, only take away the fact that each and every (mysql) operation can fail for a number of reasons; even if the exact same thing went well a thousand times before....

You haven't provided any of your code from LightFactoryRemote, so this is only a presumption, but it looks like the kind of problem you'd be seeing if you were using the bindService method on it's own.

To ensure a service is kept running, even after the activity that started it has had its onDestroy method called, you should first use startService.

The android docs for startService state:

Using startService() overrides the default service lifetime that is managed by bindService(Intent, ServiceConnection, int): it requires the service to remain running until stopService(Intent) is called, regardless of whether any clients are connected to it.

Whereas for bindService:

The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

So what's happened is the activity that bound (and therefore started) the service, has been stopped and thus the system thinks the service is no longer required and causes that error (and then probably stops the service).

Example

In this example the service should be kept running regardless of whether the calling activity is running.

ComponentName myService = startService(new Intent(this, myClass.class));
bindService(new Intent(this, myClass.class), myServiceConn, BIND_AUTO_CREATE);

The first line starts the service, and the second binds it to the activity.

Explaining if any one want to send some parameters while calling stored procedure as below,

using (SqlConnection con = new SqlConnection(connetionString))
            {
                using (var command = new SqlCommand(storedProcName, con))
                {
                    foreach (var item in sqlParams)
                    {
                        item.Direction = ParameterDirection.Input;
                        item.DbType = DbType.String;
                        command.Parameters.Add(item);
                    }
                    command.CommandType = CommandType.StoredProcedure;
                    using (var adapter = new SqlDataAdapter(command))
                    {
                        adapter.Fill(dt);
                    }
                }
            }

In your config file give the relative path

ConnectionString = "Data Source=|DataDirectory|\Database.sdf";

Change the DataDirectory to your executable path

string path = AppDomain.CurrentDomain.BaseDirectory;
AppDomain.CurrentDomain.SetData("DataDirectory", path);

If you are using EntityFramework, then you can set the DataDirectory path in your Context class

From http://hc.apache.org/httpclient-3.x/sslguide.html:

Protocol.registerProtocol("https", 
new Protocol("https", new MySSLSocketFactory(), 443));
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.whatever.com/");
try {
  httpclient.executeMethod(httpget);
      System.out.println(httpget.getStatusLine());
} finally {
      httpget.releaseConnection();
}

Where MySSLSocketFactory example can be found here. It references a TrustManager, which you can modify to trust everything (although you must consider this!)

You need to have a rmiregistry running before attempting to connect (register) a RMI service with it.

The LocateRegistry.createRegistry(2020) method call creates and exports a registry on the specified port number.

See the documentation for LocateRegistry

One of my clients was facing the same issue. Following steps are taken to fix this.

 (1) Open Run. 

 (2) Type Services.msc

 (3) Select ASP.NET State Service

 (4) Right Click and Start it.

Method A is recommended by httpclient developer community.

Please refer http://www.mail-archive.com/[email protected]/msg02455.html for more details.

Is that a proper connection string?
Where is the SQL Server instance located?

You will need to verify that you are able to conenct to SQL Server using the connection string, you specified above.

EDIT: Look at the State property of the recordset to see if it is Open?
Also, change the CursorLocation property to adUseClient before opening the recordset.

Two options:

• Install Oracle client on the PC you want to run your program on

• Use Oracle.ManagedDataAccess.dll

You can get it on NuGet (search 'oracle managed') or download ODP.NET_Managed.zip (link is to a beta version, but points you in the right direction)

I use this so that the computers I deploy onto don't need Oracle client installed.

N.B. in my opinion this is good for console apps but annoying if you intend to install your application, so I install the client in that case.

I was finally able to resolve the "Excel connection issue" in my case it was not a 64 bit issue like some of them had encounterd, I noticed the package worked fine when i didnt enable the package configuration, but i wanted my package to run with the configuration file, digging further into it i noticed i had selected all the properties that were available, I unchecked all and checked only the ones that I needed to store in the package configuration file. and ta dha it works :)

We had the same problem, because the Oracle.Data.dll assembly on a network share was updated by our DBA's. Removing the reference from the project, and adding it again solved the problem.

The article previously mentioned is good. http://forums.oracle.com/forums/thread.jspa?threadID=191750 (as far as it goes)

If this is not something that runs frequently (don't do it on your home page), you can turn off connection pooling.

There is one other "gotcha" that is not mentioned in the article. If the first thing you try to do with the connection is call a stored procedure, ODP will HANG!!!! You will not get back an error condition to manage, just a full bore HANG! The only way to fix it is to turn OFF connection pooling. Once we did that, all issues went away.

Pooling is good in some situations, but at the cost of increased complexity around the first statement of every connection.

If the error handling approach is so good, why don't they make it an option for ODP to handle it for us????

For string concatenation in C++, you should use the + operator.

nametext = "Your name is" + name;

To get the currently logged in user:

System.getProperty("user.name"); //platform independent 

and the hostname of the machine:

java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getHostName());

Adding below lines in app level build.gradle in Android project solved issue.

 compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

Just echo the first list of your source file into your target file.

echo $(head -n 1 source.txt) > target.txt

This accomplishes the same thing but is much simpler:

$(document).ready(function() {  
   $("#board").delay(1000).append(".");
});

You can chain a delay before almost any jQuery method.

To add to tacaswell's answer, the colorbar() function has an optional cax input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')

cax.set_xlabel('data label')  # cax == cb.ax

I dont get it clearly, do you want to link an external css as the structure of files you defined above? If yes then just use the link tag :

    <link rel="stylesheet" type="text/css" href="file.css">

so basically for files that are under your website folder (folder containing your index) you directly call it. For each successive folder use the "/" for example in your case :

    <link rel="stylesheet" type="text/css" href="Fonts/Font1/file name">
    <link rel="stylesheet" type="text/css" href="Fonts/Font2/file name">

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

I would advise against changing the default behaviour of a key. I do as much as possible without touching a mouse, so if you make my tab key not move to the next field on a form I will be very aggravated.

A shortcut key could be useful however, especially with large code blocks and nesting. Shift-TAB is a bad option because that normally takes me to the previous field on a form. Maybe a new button on the WMD editor to insert a code-TAB, with a shortcut key, would be possible?

The validate plugin will only validate the current/focused element.Therefore you will need to add a custom rule to the validator to validate all the checkboxes. Similar to the answer above.

$.validator.addMethod("roles", function(value, elem, param) {
   return $(".roles:checkbox:checked").length > 0;
},"You must select at least one!");

And on the element:

<input class='{roles: true}' name='roles' type='checkbox' value='1' />

In addition, you will likely find the error message display, not quite sufficient. Only 1 checkbox is highlighted and only 1 message displayed. If you click another separate checkbox, which then returns a valid for the second checkbox, the original one is still marked as invalid, and the error message is still displayed, despite the form being valid. I have always resorted to just displaying and hiding the errors myself in this case.The validator then only takes care of not submitting the form.

The other option you have is to write a function that will change the value of a hidden input to be "valid" on the click of a checkbox and then attach the validation rule to the hidden element. This will only validate in the onSubmit event though, but will display and hide messages at the appropriate times. Those are about the only options that you can use with the validate plugin.

Hope that helps!

I created a folder named a in /home/prasanth and copied your code to a file named A.java. I compiled from /home/prasanth as javac a/A.java and run javac a.A. I got output as

a!

Here is a workaround to know if softkeyboard is visible.

1. Check for running services on the system using ActivityManager.getRunningServices(max_count_of_services);
2. From the returned ActivityManager.RunningServiceInfo instances, check clientCount value for soft keyboard service.
3. The aforementioned clientCount will be incremented every time, the soft keyboard is shown. For example, if clientCount was initially 1, it would be 2 when the keyboard is shown.
4. On keyboard dismissal, clientCount is decremented. In this case, it resets to 1.

Some of the popular keyboards have certain keywords in their classNames:

Google AOSP = IME
Swype = IME
Swiftkey = KeyboardService
Fleksy = keyboard
Adaptxt = IME (KPTAdaptxtIME)
Smart = Keyboard (SmartKeyboard)

From ActivityManager.RunningServiceInfo, check for the above patterns in ClassNames. Also, ActivityManager.RunningServiceInfo's clientPackage=android, indicating that the keyboard is bound to system.

The above mentioned information could be combined for a strict way to find out if soft keyboard is visible.

All these answers and there is STILL just one missing. When you create your auth credential in the Google API section of the dev console, make sure (especially if it is your first one) that you have clicked on the 'consent screen' option. If you don't have the 'title' and any other required field filled out the call will fail with this option.

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

This will do exactly what you done in php:

var a = 1;
var b = 2;
var ccc = 3;
var name = 'a';
console.log( window[name] ); // 1

The following works for me:

git push -f origin branch_name

and it does not remove any of my code.

But, if you want to avoid this then you can do the following:

git checkout master
git pull --rebase
git checkout -b new_branch_name

then you can cherry-pick all your commits to the new branch. git cherry-pick COMMIT ID and then push your new branch.

I think these three links sum it up:

• http://tinodidriksen.com/2010/02/07/cpp-convert-int-to-string-speed/
• http://tinodidriksen.com/2010/02/16/cpp-convert-string-to-int-speed/
• http://www.fastformat.org/performance.html

stringstream and lexical_cast solutions are about the same as lexical cast is using stringstream.

Some specializations of lexical cast use different approach see http://www.boost.org/doc/libs/release/boost/lexical_cast.hpp for details. Integers and floats are now specialized for integer to string conversion.

One can specialize lexical_cast for his/her own needs and make it fast. This would be the ultimate solution satisfying all parties, clean and simple.

Articles already mentioned show comparison between different methods of converting integers <-> strings. Following approaches make sense: old c-way, spirit.karma, fastformat, simple naive loop.

Lexical_cast is ok in some cases e.g. for int to string conversion.

Converting string to int using lexical cast is not a good idea as it is 10-40 times slower than atoi depending on the platform/compiler used.

Boost.Spirit.Karma seems to be the fastest library for converting integer to string.

ex.: generate(ptr_char, int_, integer_number);

and basic simple loop from the article mentioned above is a fastest way to convert string to int, obviously not the safest one, strtol() seems like a safer solution

int naive_char_2_int(const char *p) {
    int x = 0;
    bool neg = false;
    if (*p == '-') {
        neg = true;
        ++p;
    }
    while (*p >= '0' && *p <= '9') {
        x = (x*10) + (*p - '0');
        ++p;
    }
    if (neg) {
        x = -x;
    }
    return x;
}

LINUX

I always had issues while trying paths and the spec parameter.

Therefore I went for the online solution that will update automatically the JSON on Swagger without having to reimport.

If you use npm to start your swagger editor you should add a symbolic link of your json file.

cd /path/to/your/swaggerui where index.html is.

ln -s /path/to/your/generated/swagger.json

You may encounter cache problems. The quick way to solve this was to add a token at the end of my url...

window.onload = function() {

var noCache = Math.floor((Math.random() * 1000000) + 1);

// Build a system
const editor = SwaggerEditorBundle({
url: "http://localhost:3001/swagger.json?"+noCache,
  dom_id: '#swagger-editor',
  layout: 'StandaloneLayout',
  presets: [
    SwaggerEditorStandalonePreset
  ]
})

window.editor = editor
}

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

I recently had the same issue. It's more likely that your application can not connect to database server due to the network issues.

In my case I was connected to wrong WiFi.

It looks like XMLHttpRequest has been replaced by the Fetch API. Google published a good introduction that includes this example doing what you want:

fetch('./api/some.json')
  .then(
    function(response) {
      if (response.status !== 200) {
        console.log('Looks like there was a problem. Status Code: ' +
          response.status);
        return;
      }

      // Examine the text in the response
      response.json().then(function(data) {
        console.log(data);
      });
    }
  )
  .catch(function(err) {
    console.log('Fetch Error :-S', err);
  });

However, you probably want to call response.text() instead of response.json().

By calling fork() you've created a child process. If the fork is successful (fork returned a non-zero PID) execution will continue from this point from within the child process. In this case we want to gracefully exit the parent process and then continue our work in the child process.

Maybe this will help: http://www.netzmafia.de/skripten/unix/linux-daemon-howto.html

Since your coordinates belong together as pairs, why not write a struct for them?

struct CoordinatePair
{
    int x;
    int y;
};

Then you can write an overloaded extraction operator for istreams:

std::istream& operator>>(std::istream& is, CoordinatePair& coordinates)
{
    is >> coordinates.x >> coordinates.y;

    return is;
}

And then you can read a file of coordinates straight into a vector like this:

#include <fstream>
#include <iterator>
#include <vector>

int main()
{
    char filename[] = "coordinates.txt";
    std::vector<CoordinatePair> v;
    std::ifstream ifs(filename);
    if (ifs) {
        std::copy(std::istream_iterator<CoordinatePair>(ifs), 
                std::istream_iterator<CoordinatePair>(),
                std::back_inserter(v));
    }
    else {
        std::cerr << "Couldn't open " << filename << " for reading\n";
    }
    // Now you can work with the contents of v
}

In an attempt to spot a change somewhere in a particular column (here in "W", i.e. "23"), I modified Peter Alberts' answer to:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Target.Column = 23 Then Exit Sub
    Application.EnableEvents = False             'to prevent endless loop
    On Error GoTo Finalize                       'to re-enable the events
    MsgBox "You changed a cell in column W, row " & Target.Row
    MsgBox "You changed it to: " & Target.Value
Finalize:
    Application.EnableEvents = True
End Sub

Define the following function (not mine, not sure where I found it long ago):

private static String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
    while ((line = reader.readLine()) != null) {
        sb.append(line + "\n");
    }
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        is.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
return sb.toString();

}

Then:

String jsonReply;
if(conn.getResponseCode()==201 || conn.getResponseCode()==200)
    {
        success = true;
        InputStream response = conn.getInputStream();
        jsonReply = convertStreamToString(response);

        // Do JSON handling here....
    }

the Best of both worlds.....

Private Sub tsbSendNewsLetter_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbSendNewsLetter.Click
        Dim tmpstr As String = ""
        Dim cnt As Integer = 0
        Dim virgin As Boolean = True
        For cnt = 0 To (dgvDetails.Rows.Count - 1)
            If Not dgvContacts.Rows(cnt).Cells(9).Value.ToString() Is Nothing Then
                If Not dgvContacts.Rows(cnt).Cells(9).Value.ToString().Length = 0 Then
                    If Not virgin Then
                        tmpstr += ", "
                    End If
                    tmpstr += dgvContacts.Rows(cnt).Cells(9).Value.ToString()
                    virgin = False
                    'MsgBox(tmpstr)
                End If
            End If
        Next
        Dim email As New qkuantusMailer()
        email.txtMailTo.Text = tmpstr
        email.Show()
    End Sub

If your path contains comma's, putting quotes around the path will work when using Process.Start(ProcessStartInfo).

It will NOT work when using Process.Start(string, string) however. It seems like Process.Start(string, string) actually removes the quotes inside of your args.

Here is a simple example that works for me.

string p = @"C:\tmp\this path contains spaces, and,commas\target.txt";
string args = string.Format("/e, /select, \"{0}\"", p);

ProcessStartInfo info = new ProcessStartInfo();
info.FileName = "explorer";
info.Arguments = args;
Process.Start(info);

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

This is how you do it

SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS 
FROM TABLE 
ORDER BY SUM_COUNTS LIMIT 20

The SUM function will add up all rows, so the order by clause is useless, instead you will have to use the group by clause.

<script>
var someSession = '<%= Session["SessionName"].ToString() %>';
alert(someSession)
</script>

This code you can write in Aspx. If you want this in some js.file, you have two ways:

1. Make aspx file which writes complete JS code, and set source of this file as Script src
2. Make handler, to process JS file as aspx.

take a look at codenameone.com project, it's a cross platform mobile framework where the ui part is a fork of LWUIT. This project leverage xmlvm to translates the java bytes code to Objective C

You should use the Spring Boot Maven Plugin:

<project>  
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.5.1.RELEASE</version>
        <configuration>
          <profiles>
            <profile>foo</profile>
            <profile>bar</profile>
          </profiles>
        </configuration>
        ...

With Swift 5 and iOS 12.3, according to your needs, you may choose one of the 3 following ways in order to solve your problem.

#1. Using UIView's animate(withDuration:animations:) class method

animate(withDuration:animations:) has the following declaration:

Animate changes to one or more views using the specified duration.

class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)

The Playground code below shows a possible implementation of animate(withDuration:animations:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIView.animate(withDuration: 2) {
            self.view.layoutIfNeeded()
        }
    }

}

PlaygroundPage.current.liveView = ViewController()

#2. Using UIViewPropertyAnimator's init(duration:curve:animations:) initialiser and startAnimation() method

init(duration:curve:animations:) has the following declaration:

Initializes the animator with a built-in UIKit timing curve.

convenience init(duration: TimeInterval, curve: UIViewAnimationCurve, animations: (() -> Void)? = nil)

The Playground code below shows a possible implementation of init(duration:curve:animations:) and startAnimation() in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        let animator = UIViewPropertyAnimator(duration: 2, curve: .linear, animations: {
            self.view.layoutIfNeeded()
        })
        animator.startAnimation()
    }

}

PlaygroundPage.current.liveView = ViewController()

#3. Using UIViewPropertyAnimator's runningPropertyAnimator(withDuration:delay:options:animations:completion:) class method

runningPropertyAnimator(withDuration:delay:options:animations:completion:) has the following declaration:

Creates and returns an animator object that begins running its animations immediately.

class func runningPropertyAnimator(withDuration duration: TimeInterval, delay: TimeInterval, options: UIViewAnimationOptions = [], animations: @escaping () -> Void, completion: ((UIViewAnimatingPosition) -> Void)? = nil) -> Self

The Playground code below shows a possible implementation of runningPropertyAnimator(withDuration:delay:options:animations:completion:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIViewPropertyAnimator.runningPropertyAnimator(withDuration: 2, delay: 0, options: [], animations: {
            self.view.layoutIfNeeded()
        })
    }

}

PlaygroundPage.current.liveView = ViewController()

Edit your phpmyadmin config.inc.php file and if you have Password, insert that in front of Password in following code:

$cfg['Servers'][$i]['verbose'] = 'localhost';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = '**your-root-username**';
$cfg['Servers'][$i]['password'] = '**root-password**';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

Google declares that this is not a failure, but some "misleading error reports". This bug will be fixed in version 40 of chrome.

You could create an animation and apply it to your button view. For example:

    // Locate view
    ImageView diskView = (ImageView) findViewById(R.id.imageView3);

    // Create an animation instance
    Animation an = new RotateAnimation(0.0f, 360.0f, pivotX, pivotY);

    // Set the animation's parameters
    an.setDuration(10000);               // duration in ms
    an.setRepeatCount(0);                // -1 = infinite repeated
    an.setRepeatMode(Animation.REVERSE); // reverses each repeat
    an.setFillAfter(true);               // keep rotation after animation

    // Aply animation to image view
    diskView.setAnimation(an);

Here you've got a very detailed explanation of their differences

http://kyleschaeffer.com/development/css-font-size-em-vs-px-vs-pt-vs/

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

WHERE something IS NULL

and

WHERE something IS NOT NULL

def quick_sort(list):
    if len(list) ==0:
        return []

    return  quick_sort(filter( lambda item: item < list[0],list)) + [v for v in list if v==list[0] ]  +  quick_sort( filter( lambda item: item > list[0], list))

It is a self-executing anonymous function. The first set of brackets contain the expressions to be executed, and the second set of brackets executes those expressions.

(function () {
    return ( 10 + 20 );
})();

Peter Michaux discusses the difference in An Important Pair of Parentheses.

It is a useful construct when trying to hide variables from the parent namespace. All the code within the function is contained in the private scope of the function, meaning it can't be accessed at all from outside the function, making it truly private.

See:

1. Closure (computer science)
2. JavaScript Namespacing
3. Important Pair of Javascript Parentheses

Update (31/03/2019) : All icon themes work via Google Web Fonts now.

As pointed out by Edric, it's just a matter of adding the google web fonts link in your document's head now, like so:

<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp" rel="stylesheet">

And then adding the correct class to output the icon of a particular theme.

<i class="material-icons">donut_small</i>
<i class="material-icons-outlined">donut_small</i>
<i class="material-icons-two-tone">donut_small</i>
<i class="material-icons-round">donut_small</i>
<i class="material-icons-sharp">donut_small</i>

The color of the icons can be changed using CSS as well.

Note: the Two-tone theme icons are a bit glitchy at present.

Update (14/11/2018) : List of 16 outline icons that work with the "_outline" suffix.

Here's the most recent list of 16 outline icons that work with the regular Material-icons Webfont, using the _outline suffix (tested and confirmed).

(As found on the material-design-icons github page. Search for: "_outline_24px.svg")

<i class="material-icons">help_outline</i>
<i class="material-icons">label_outline</i>
<i class="material-icons">mail_outline</i>
<i class="material-icons">info_outline</i>
<i class="material-icons">lock_outline</i>
<i class="material-icons">lightbulb_outline</i>
<i class="material-icons">play_circle_outline</i>
<i class="material-icons">error_outline</i>
<i class="material-icons">add_circle_outline</i>
<i class="material-icons">people_outline</i>
<i class="material-icons">person_outline</i>
<i class="material-icons">pause_circle_outline</i>
<i class="material-icons">chat_bubble_outline</i>
<i class="material-icons">remove_circle_outline</i>
<i class="material-icons">check_box_outline_blank</i>
<i class="material-icons">pie_chart_outlined</i>

Note that pie_chart needs to be "pie_chart_outlined" and not outline.

This is a hack to test out the new icon themes using an inline tag. It's not the official solution.

As of today (July 19, 2018), a little over 2 months since the new icons themes were introduced, there is No Way to include these icons using an inline tag <i class="material-icons"></i>.

+Martin has pointed out that there's an issue raised on Github regarding the same: https://github.com/google/material-design-icons/issues/773

So, until Google comes up with a solution for this, I've started using a hack to include these new icon themes in my development environment before downloading the appropriate icons as SVG or PNG. And I thought I'd share it with you all.

IMPORTANT: Do not use this on a production environment as each of the included CSS files from Google are over 1MB in size.

Google uses these stylesheets to showcase the icons on their demo page:

Outline:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">

Rounded:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/round.css">

Two-Tone:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/twotone.css">

Sharp:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">

Each of these files contain the icons of the respective themes included as background-images (Base64 image-data). And here's how we can use this to test out the compatibility of a particular icon in our design before downloading it for use in the production environment.

STEP 1:

Include the stylesheet of the theme that you want to use. Eg: For the 'Outlined' theme, use the stylesheet for 'outline.css'

STEP 2:

Add the following classes to your own stylesheet:

.material-icons-new {
    display: inline-block;
    width: 24px;
    height: 24px;
    background-repeat: no-repeat;
    background-size: contain;
}

.icon-white {
    webkit-filter: contrast(4) invert(1);
    -moz-filter: contrast(4) invert(1);
    -o-filter: contrast(4) invert(1);
    -ms-filter: contrast(4) invert(1);
    filter: contrast(4) invert(1);
}

STEP 3:

Use the icon by adding the following classes to the <i> tag:

1. material-icons-new class

2. Icon name as shown on the material icons demo page, prefixed with the theme name followed by a hyphen.

Prefixes:

Outlined: outline-

Rounded: round-

Two-Tone: twotone-

Sharp: sharp-

Eg (for 'announcement' icon):

outline-announcement, round-announcement, twotone-announcement, sharp-announcement

3) Use an optional 3rd class icon-white for inverting the color from black to white (for dark backgrounds)

Changing icon size:

Since this is a background-image and not a font-icon, use the height and width properties of CSS to modify the size of the icons. The default is set to 24px in the material-icons-new class.

Example:

Case I: For the Outlined Theme of the account_circle icon:

1. Include the stylesheet:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/outline.css">

2. Add the icon tag on your page:

<i class="material-icons-new outline-account_circle"></i>

Optional (For dark backgrounds):

<i class="material-icons-new outline-account_circle icon-white"></i>

Case II: For the Sharp Theme of the assessment icon:

1. Include the stylesheet:

<link rel="stylesheet" href="https://storage.googleapis.com/non-spec-apps/mio-icons/latest/sharp.css">

2. Add the icon tag on your page:

<i class="material-icons-new sharp-assessment"></i>

(For dark backgrounds):

<i class="material-icons-new sharp-assessment icon-white"></i>

I can't stress enough that this is NOT THE RIGHT WAY to include the icons on your production environment. But if you have to scan through multiple icons on your in-development page, it does make the icon inclusion pretty easy and saves a lot of time.

Downloading the icon as SVG or PNG sure is a better option when it comes to site-speed optimization, but font-icons are a time-saver when it comes to the prototyping phase and checking if a particular icon goes with your design, etc.

I will update this post if and when Google comes up with a solution for this issue that does not involve downloading an icon for usage.

This is the XML optional preamble.

• version="1.0" means that this is the XML standard this file conforms to
• encoding="utf-8" means that the file is encoded using the UTF-8 Unicode encoding

This is not a problem with the function at all.

It took me a bit of digging, but the problem is in copying and pasting. Try copying this: RANDBETWEEN(0,6553??5) string, posted in your original question, and paste it into a Hex Editor, then you'll see that there are actually two null characters in the 65535:

00000000  52 41 4E 44 42 45 54 57 45 45 4E 28 30 2C 36 35  RANDBETWEEN(0,65
00000010  35 33 00 00 35 29                                53?..?5)

Use .children instead:

from bs4 import NavigableString, Comment
print ''.join(unicode(child) for child in hit.children 
    if isinstance(child, NavigableString) and not isinstance(child, Comment))

Yes, this is a bit of a dance.

Output:

>>> for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
...     print ''.join(unicode(child) for child in hit.children 
...         if isinstance(child, NavigableString) and not isinstance(child, Comment))
... 




      THIS IS MY TEXT

As stated in other answers, the simplest method is to uniquely identify the root element (by ID or class name) and use the direct descendent selector.

$('ul.topMenu > li > a')

However, I came across this question in search of a solution which would work on unnamed elements at varying depths of the DOM.

This can be achieved by checking each element, and ensuring it does not have a parent in the list of matched elements. Here is my solution, wrapped in a jQuery selector 'topmost'.

jQuery.extend(jQuery.expr[':'], {
  topmost: function (e, index, match, array) {
    for (var i = 0; i < array.length; i++) {
      if (array[i] !== false && $(e).parents().index(array[i]) >= 0) {
        return false;
      }
    }
    return true;
  }
});

Utilizing this, the solution to the original post is:

$('ul:topmost > li > a')

// Or, more simply:
$('li:topmost > a')

Complete jsFiddle available here.

I found this question as the top result while Googling how to find the owner of a table in Oracle, so I thought that I would contribute a table specific answer for others' convenience.

To find the owner of a specific table in an Oracle DB, use the following query:

select owner from ALL_TABLES where TABLE_NAME ='<MY-TABLE-NAME>';

Yes, you can do this. For example, to style the td tags that make up the different columns of a table you could do something like this:

table.myClass tr > td:first-child /* First column */
{
  /* some style here */
}
table.myClass tr > td:first-child+td /* Second column */
{
  /* some style here */
}
table.myClass tr > td:first-child+td+td /* Third column */
{
  /* some style here */
}

For this html:

<div class="outer">
     <div class="inner"></div>
</div>

This selector should work:

$('.outer > .inner')

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

This version is similar to chiborg's answer, but it eliminates the need for the external tty and cat. It uses date, but could just as easily use gawk. You can change the shebang and replace the double square brackets with single ones and this will also run in sh.

#!/bin/bash
LANG=C
if [[ -z "$1" ]]
then
    if [[ -p /dev/stdin ]]    # input from a pipe
    then
        read -r p
    else
        echo "No timestamp given." >&2
        exit
    fi
else
    p=$1
fi
date -d "@$p" +%c

Simple way to compare time is :

$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
     // your code
}

Maybe: UPDATE test SET data = '"my-other-name"'::json WHERE id = 1;

It worked with my case, where data is a json type

I'm using angular2-moment, but usage must be similar.

import { MomentModule } from "angular2-moment";
import moment = require("moment");

export class AppModule {

  constructor() {
    moment.locale('ru');
  }
}

You have to add a folder to the Sublime Text window in order to navigate via the sidebar. Go to File -> Open Folder... and select the highest directory you want to be able to navigate.

Also, 'View -> Sidebar -> Show Sidebar' if it still doesn't show. In the new version, there is only an 'open' menu and no separate option for opening a folder.

This is the best way I've seen to find the last cell.

MsgBox ActiveSheet.UsedRage.SpecialCells(xlCellTypeLastCell).Row

One of the disadvantages to using this is that it's not always accurate. If you use it then delete the last few rows and use it again, it does not always update. Saving your workbook before using this seems to force it to update though.

Using the next bit of code after updating the table (or refreshing the query that feeds the table) forces everything to update before finding the last row. But, it's been reported that it makes excel crash. Either way, calling this before trying to find the last row will ensure the table has finished updating first.

Application.CalculateUntilAsyncQueriesDone

Another way to get the last row for any given column, if you don't mind the overhead.

Function GetLastRow(col, row)
    ' col and row are where we will start.
    ' We will find the last row for the given column.
    Do Until ActiveSheet.Cells(row, col) = ""
        row = row + 1
    Loop
    GetLastRow = row
End Function

Python comes with numerous ways of formatting strings:

New style .format(), which supports a rich formatting mini-language:

>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!

Old style % format specifier:

>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!

In Py 3.6 using the new f"" format strings:

>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!

Or using print()s default separator:

>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!

And least effectively, construct a new string by casting it to a str() and concatenating:

>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!

Or join()ing it:

>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

Will not necessarily work

• Backup / Restore - will not work when the target is an earlier MS SQL version.

• Copy Database - will not work when the target is SQL Server Express: "The destination server cannot be a SQL Server 2005 or later Express instance."

• Data import - Will not copy the schema.

Will work

• Script generation - Tasks -> Generate Scripts. Make sure you set the desired target SQL Server version on the Set Scripting Options -> Advanced page. You can also choose there whether to copy schema, data, or both. Note that in the generated script, you may need to change the DATA folder for the mdf/ldf files if moving from non-express to express or vice versa.

• Microsoft SQL Server Database Publishing Services - comes with SQL Server 2005 and above, I think. Download the latest version from here. Prerequisites: sqlncli.msi/sqlncli_x64.msi/sqlncli_ia64.msi, SQLServer2005_XMO.msi/SQLServer2005_XMO_x64.msi/SQLServer2005_XMO_ia64.msi (download here).

You can also use truncate.

truncate table table_name;

This will help:

If you are looking into Amazon products then you should be using the official API. There is at least one Python package that will ease your scraping issues and keep your activity within the terms of use.

This one works for me.

It is simpler then Rj0078's answer in this question (https://stackoverflow.com/a/42556648/11211963), but that one is worked as well.

It shows a dialog like this:

There is no need to compute trigonometric functions. The simple code in C language is:

#include <math.h>
#define PIV2 M_PI+M_PI
#define C360 360.0000000000000000000
double difangrad(double x, double y)
{
double arg;

arg = fmod(y-x, PIV2);
if (arg < 0 )  arg  = arg + PIV2;
if (arg > M_PI) arg  = arg - PIV2;

return (-arg);
}
double difangdeg(double x, double y)
{
double arg;
arg = fmod(y-x, C360);
if (arg < 0 )  arg  = arg + C360;
if (arg > 180) arg  = arg - C360;
return (-arg);
}

let dif = a - b , in radians

dif = difangrad(a,b);

let dif = a - b , in degrees

dif = difangdeg(a,b);

difangdeg(180.000000 , -180.000000) = 0.000000
difangdeg(-180.000000 , 180.000000) = -0.000000
difangdeg(359.000000 , 1.000000) = -2.000000
difangdeg(1.000000 , 359.000000) = 2.000000

It really is an "it depends" kinda question. Some general points:

• NoSQL is typically good for unstructured/"schemaless" data - usually, you don't need to explicitly define your schema up front and can just include new fields without any ceremony
• NoSQL typically favours a denormalised schema due to no support for JOINs per the RDBMS world. So you would usually have a flattened, denormalized representation of your data.
• Using NoSQL doesn't mean you could lose data. Different DBs have different strategies. e.g. MongoDB - you can essentially choose what level to trade off performance vs potential for data loss - best performance = greater scope for data loss.
• It's often very easy to scale out NoSQL solutions. Adding more nodes to replicate data to is one way to a) offer more scalability and b) offer more protection against data loss if one node goes down. But again, depends on the NoSQL DB/configuration. NoSQL does not necessarily mean "data loss" like you infer.
• IMHO, complex/dynamic queries/reporting are best served from an RDBMS. Often the query functionality for a NoSQL DB is limited.
• It doesn't have to be a 1 or the other choice. My experience has been using RDBMS in conjunction with NoSQL for certain use cases.
• NoSQL DBs often lack the ability to perform atomic operations across multiple "tables".

You really need to look at and understand what the various types of NoSQL stores are, and how they go about providing scalability/data security etc. It's difficult to give an across-the-board answer as they really are all different and tackle things differently.

For MongoDb as an example, check out their Use Cases to see what they suggest as being "well suited" and "less well suited" uses of MongoDb.

Try setting your ScriptManager to this.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" /> 

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

I am using the AMD processor and had the same issue. To solve this go to control panel-> turn windows features on or off -> check the hyper-V checkbox and click Ok and restart your computer. Now you can create virtual device

Hendry's answer is 100% correct. I had the same problem with my application, where there is repository project dealing with database with use of methods encapsulating EF db context operation. Other projects use this repository, and I don't want to reference EF in those projects. Somehow I don't feel it's proper, I need EF only in repository project. Anyway, copying EntityFramework.SqlServer.dll to other project output directory solves the problem. To avoid problems, when you forget to copy this dll, you can change repository build directory. Go to repository project's properties, select Build tab, and in output section you can set output directory to other project's build directory. Sure, it's just workaround. Maybe the hack, mentioned in some placec, is better:

var instance = System.Data.Entity.SqlServer.SqlProviderServices.Instance;

Still, for development purposes it is enough. Later, when preparing install or publish, you can add this file to package.

I'm quite new to EF. Is there any better method to solve this issue? I don't like "hack" - it makes me feel that there is something that is "not secure".

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

In my case, to use Pageable and Sorting at the same time I used like below. In this case I took all elements using pagination and sorting by id by descending order:

modelRepository.findAll(PageRequest.of(page, 10, Sort.by("id").descending()))

Like above based on your requirements you can sort data with 2 columns as well.

This works for me. Will provide last day of given year and month:

var d = new Date(2012,02,0);
var n = d.getDate();
alert(n);

There might be different reasons for different people. For me these are the advantages.

1. Provides an integrated feel to the project. For instance i will have all the related projects files in single view.
2. Provides increased code productivity like
   1. Syntax Highlighting
   2. Referring of assemblies
   3. Intellisense
   4. Centralized view of database and related UI files.
   5. Debugging features

End of the day, it helps me to code faster than i can do in a notepad or wordpad. That is a pretty good reason for me to prefer an IDE.

mongoimport original.json -d databaseName -c yourcollectionName --jsonArray --drop

I have a case where I am transforming a legacy DB2 z/os database timestamp (formatted as: "yyyy-MM-dd'T'HH:mm:ss.SSSZ") into a SqlServer 2016 datetime2 (formatted as: "yyyy-MM-dd HH:mm:ss.SSS) field that is handled by our Spring/Hibernate Entity Manager instance (in this case, the OldRevision Table). In the Class, I define the date as the java.util type, and write the setter and getter in the normal way. Then, When handling the data, the code I have handling the data related to this question looks like this:

OldRevision revision = new OldRevision();
String oldRevisionDateString= oldRevisionData.getString("originalRevisionDate", "");
Date oldDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
oldDateFormat.parse(oldRevisionDateString);
SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
Date finalFormattedDate= newDateFormat.parse(newDateFormat.format(oldDateFormat));
revision.setOriginalRevisionDate(finalFormattedDate);
em.persist(revision);

A simpler way to do the same case is:

SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
newDateFormat.setTimeZone(TimeZone.getTimeZone("EST"));
revision.setOriginalRevisionDate(
        newDateFormat.parse(newDateFormat.format(
                new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ")

Cantor pairing function is really one of the better ones out there considering its simple, fast and space efficient, but there is something even better published at Wolfram by Matthew Szudzik, here. The limitation of Cantor pairing function (relatively) is that the range of encoded results doesn't always stay within the limits of a 2N bit integer if the inputs are two N bit integers. That is, if my inputs are two 16 bit integers ranging from 0 to 2^16 -1, then there are 2^16 * (2^16 -1) combinations of inputs possible, so by the obvious Pigeonhole Principle, we need an output of size at least 2^16 * (2^16 -1), which is equal to 2^32 - 2^16, or in other words, a map of 32 bit numbers should be feasible ideally. This may not be of little practical importance in programming world.

Cantor pairing function:

(a + b) * (a + b + 1) / 2 + a; where a, b >= 0

The mapping for two maximum most 16 bit integers (65535, 65535) will be 8589803520 which as you see cannot be fit into 32 bits.

Enter Szudzik's function:

a >= b ? a * a + a + b : a + b * b;  where a, b >= 0

The mapping for (65535, 65535) will now be 4294967295 which as you see is a 32 bit (0 to 2^32 -1) integer. This is where this solution is ideal, it simply utilizes every single point in that space, so nothing can get more space efficient.

Now considering the fact that we typically deal with the signed implementations of numbers of various sizes in languages/frameworks, let's consider signed 16 bit integers ranging from -(2^15) to 2^15 -1 (later we'll see how to extend even the ouput to span over signed range). Since a and b have to be positive they range from 0 to 2^15 - 1.

Cantor pairing function:

The mapping for two maximum most 16 bit signed integers (32767, 32767) will be 2147418112 which is just short of maximum value for signed 32 bit integer.

Now Szudzik's function:

(32767, 32767) => 1073741823, much smaller..

Let's account for negative integers. That's beyond the original question I know, but just elaborating to help future visitors.

Cantor pairing function:

A = a >= 0 ? 2 * a : -2 * a - 1;
B = b >= 0 ? 2 * b : -2 * b - 1;
(A + B) * (A + B + 1) / 2 + A;

(-32768, -32768) => 8589803520 which is Int64. 64 bit output for 16 bit inputs may be so unpardonable!!

Szudzik's function:

A = a >= 0 ? 2 * a : -2 * a - 1;
B = b >= 0 ? 2 * b : -2 * b - 1;
A >= B ? A * A + A + B : A + B * B;

(-32768, -32768) => 4294967295 which is 32 bit for unsigned range or 64 bit for signed range, but still better.

Now all this while the output has always been positive. In signed world, it will be even more space saving if we could transfer half the output to negative axis. You could do it like this for Szudzik's:

A = a >= 0 ? 2 * a : -2 * a - 1;
B = b >= 0 ? 2 * b : -2 * b - 1;
C = (A >= B ? A * A + A + B : A + B * B) / 2;
a < 0 && b < 0 || a >= 0 && b >= 0 ? C : -C - 1;

(-32768, 32767) => -2147483648

(32767, -32768) => -2147450880

(0, 0) => 0 

(32767, 32767) => 2147418112

(-32768, -32768) => 2147483647

What I do: After applying a weight of 2 to the the inputs and going through the function, I then divide the ouput by two and take some of them to negative axis by multiplying by -1.

See the results, for any input in the range of a signed 16 bit number, the output lies within the limits of a signed 32 bit integer which is cool. I'm not sure how to go about the same way for Cantor pairing function but didn't try as much as its not as efficient. Furthermore, more calculations involved in Cantor pairing function means its slower too.

Here is a C# implementation.

public static long PerfectlyHashThem(int a, int b)
{
    var A = (ulong)(a >= 0 ? 2 * (long)a : -2 * (long)a - 1);
    var B = (ulong)(b >= 0 ? 2 * (long)b : -2 * (long)b - 1);
    var C = (long)((A >= B ? A * A + A + B : A + B * B) / 2);
    return a < 0 && b < 0 || a >= 0 && b >= 0 ? C : -C - 1;
}

public static int PerfectlyHashThem(short a, short b)
{
    var A = (uint)(a >= 0 ? 2 * a : -2 * a - 1);
    var B = (uint)(b >= 0 ? 2 * b : -2 * b - 1);
    var C = (int)((A >= B ? A * A + A + B : A + B * B) / 2);
    return a < 0 && b < 0 || a >= 0 && b >= 0 ? C : -C - 1;
}

Since the intermediate calculations can exceed limits of 2N signed integer, I have used 4N integer type (the last division by 2 brings back the result to 2N).

The link I have provided on alternate solution nicely depicts a graph of the function utilizing every single point in space. Its amazing to see that you could uniquely encode a pair of coordinates to a single number reversibly! Magic world of numbers!!

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

The innerHTML fetches content depending on the id/name and replaces them.

<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
 <title>Learn JavaScript</title>_x000D_
</head>_x000D_
<body>_x000D_
<button type = "button"_x000D_
onclick="document.getElementById('demo').innerHTML = Date()"> <!--fetches the content with id demo and changes the innerHTML content to Date()-->_x000D_
Click for date_x000D_
</button>_x000D_
<h3 id = 'demo'>Before Button is clicked this content will be Displayed the inner content of h3 tag with id demo and once you click the button this will be replaced by the Date() ,which prints the current date and time </h3> _x000D_
_x000D_
</body>_x000D_
</html>

When you click the button,the content in h3 will be replaced by innerHTML assignent i.e Date() .

By design make parser executes lines in a separate shell invocations, that's why changing variable (e.g. PATH) in one line, the change may not be applied for the next lines (see this post).

One way to workaround this problem, is to convert multiple commands into a single line (separated by ;), or use One Shell special target (.ONESHELL, as of GNU Make 3.82).

Alternatively you can provide PATH variable at the time when shell is invoked. For example:

PATH  := $(PATH):$(PWD)/bin:/my/other/path
SHELL := env PATH=$(PATH) /bin/bash

Actually only Jon's answer (Sep 5 '11 at 9:37) with BaseStream.Seek worked for my case. Thanks Jon! I needed to append lines to a zip archived txt file.

using (FileStream zipFS = new FileStream(@"c:\Temp\SFImport\test.zip",FileMode.OpenOrCreate))
{
    using (ZipArchive arch = new ZipArchive(zipFS,ZipArchiveMode.Update))
    {
        ZipArchiveEntry entry = arch.GetEntry("testfile.txt");
        if (entry == null)
        {
            entry = arch.CreateEntry("testfile.txt");
        }
        using (StreamWriter sw = new StreamWriter(entry.Open()))
        {
            sw.BaseStream.Seek(0,SeekOrigin.End);
            sw.WriteLine("text content");
        }
    }
}

2 things to understand here -

1) If you are casting Primitive interger to Primitive double . It works. e.g. It works fine.

int pri=12; System.out.println((double)pri);

2) if you try to Cast Integer object to Double object or vice - versa , It fails.

Integer a = 1; Double b = (double) a; // WRONG. Fails with class cast excptn

Solution -

Soln 1) Integer i = 1; Double b = new Double(i);
soln 2) Double d = 2.0; Integer x = d.intValue();

In Rails 2

l = Location.find(:id => id, :select => "name, website, city", :limit => 1)

...or...

l = Location.find_by_sql(:conditions => ["SELECT name, website, city FROM locations WHERE id = ? LIMIT 1", id])

This reference doc gives you the entire list of options you can use with .find, including how to limit by number, id, or any other arbitrary column/constraint.

In Rails 3 w/ActiveRecord Query Interface

l = Location.where(["id = ?", id]).select("name, website, city").first

Ref: Active Record Query Interface

You can also swap the order of these chained calls, doing .select(...).where(...).first - all these calls do is construct the SQL query and then send it off.

Use mcrypt_encrypt() and mcrypt_decrypt() with corresponding parameters. Really easy and straight forward, and you use a battle-tested encryption package.

EDIT

5 years and 4 months after this answer, the mcrypt extension is now in the process of deprecation and eventual removal from PHP.

JavaScript will "convert" numeric string to integer, if you perform calculations on it (as JS is weakly typed). But you can convert it yourself using parseInt or parseFloat.

Just remember to put radix in parseInt!

In case of integer inputs:

var x = parseInt(prompt("Enter a Value", "0"), 10);
var y = parseInt(prompt("Enter a Value", "0"), 10);

In case of float:

var x = parseFloat(prompt("Enter a Value", "0"));
var y = parseFloat(prompt("Enter a Value", "0"));

I came across the same issue while working on a selenium project(maven). The Project folder and pom.xml were showing red cross symbol. This was coming as i had the test datasheet open. I could remove the error by just closing the datasheet and the never faced the issue again

If you need to run request as the current user from desktop application use CredentialCache.DefaultCredentials (see on MSDN).

Your code looks fine if you need to run a request from server side code or under a different user.

Please note that you should be careful when storing passwords - consider using the SecureString version of the constructor.

This annotation is commonly used to eliminate NullPointerExceptions. @Nullable says that this parameter might be null. A good example of such behaviour can be found in Google Guice. In this lightweight dependency injection framework you can tell that this dependency might be null. If you would try to pass null without an annotation the framework would refuse to do it's job.

What is more @Nullable might be used with @NotNull annotation. Here you can find some tips on how to use them properly. Code inspection in IntelliJ checks the annotations and helps to debug the code.

If you really want it to be FAST on Windows, you can do it using unsafe code with CopyMemory. CopyMemory is about 5x faster (e.g. 800MB of data takes 3s to copy via marshalling, while only taking .6s to copy via CopyMemory). This method does limit you to using only data which is actually stored in the struct blob itself, e.g. numbers, or fixed length byte arrays.

    [DllImport("kernel32.dll", EntryPoint = "CopyMemory", SetLastError = false)]
    private static unsafe extern void CopyMemory(void *dest, void *src, int count);

    private static unsafe byte[] Serialize(TestStruct[] index)
    {
        var buffer = new byte[Marshal.SizeOf(typeof(TestStruct)) * index.Length];
        fixed (void* d = &buffer[0])
        {
            fixed (void* s = &index[0])
            {
                CopyMemory(d, s, buffer.Length);
            }
        }

        return buffer;
    }

I encountered this problem when I was installing react packages and this worked for me: npm install --save <package causing this error>

Since the question specified rounding for doubles specifically, this seems way simpler than dealing with big integer or excessive string or numerical operations.

"%.2f".format(0.714999999999).toDouble

A shorter example

private static final Charset UTF_8 = Charset.forName("UTF-8");

String text = "Hello World!";
byte[] bytes = text.getBytes(UTF_8);
System.out.println("bytes= "+Arrays.toString(bytes));
System.out.println("text again= "+new String(bytes, UTF_8));

prints

bytes= [72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33]
text again= Hello World!

It is not possible to kill the session variable, when the machine unexpectly shutdown due to power failure. It is only possible when the user is idle for a long time or it is properly logout.

CSS to detect screen orientation:

 @media screen and (orientation:portrait) { … }
 @media screen and (orientation:landscape) { … }

The CSS definition of a media query is at http://www.w3.org/TR/css3-mediaqueries/#orientation

There are a couple of ways to do that. I normally fall back to just using something like this:

long start = System.currentTimeMillis();
// ... do something ...
long end = System.currentTimeMillis();

or the same thing with System.nanoTime();

For something more on the benchmarking side of things there seems also to be this one: http://jetm.void.fm/ Never tried it though.

A shorter solution using data.table:

setDT(group)[, .SD[which.max(pt)], by=Subject]
#    Subject pt Event
# 1:       1  5     2
# 2:       2 17     2
# 3:       3  5     2

Whenever possible, you should avoid parsing the output of ls (see Greg's wiki on the subject). Basically, the output of ls will be ambiguous if there are funny characters in any of the filenames. It's also usually a waste of time. In this case, when you execute ls -d */, what happens is that the shell expands */ to a list of subdirectories (which is already exactly what you want), passes that list as arguments to ls -d, which looks at each one, says "yep, that's a directory all right" and prints it (in an inconsistent and sometimes ambiguous format). The ls command isn't doing anything useful!

Well, ok, it is doing one thing that's useful: if there are no subdirectories, */ will get left as is, ls will look for a subdirectory named "*", not find it, print an error message that it doesn't exist (to stderr), and not print the "*/" (to stdout).

The cleaner way to make an array of subdirectory names is to use the glob (*/) without passing it to ls. But in order to avoid putting "*/" in the array if there are no actual subdirectories, you should set nullglob first (again, see Greg's wiki):

shopt -s nullglob
array=(*/)
shopt -u nullglob # Turn off nullglob to make sure it doesn't interfere with anything later
echo "${array[@]}"  # Note double-quotes to avoid extra parsing of funny characters in filenames

If you want to print an error message if there are no subdirectories, you're better off doing it yourself:

if (( ${#array[@]} == 0 )); then
    echo "No subdirectories found" >&2
fi

if you want to reload your entire page, like it seems, just inject $window into your controller and then call

$window.location.href = '/';

but if you only want to reload your current view, inject $scope, $state and $stateParams (the latter just in case you need to have some parameters change in this upcoming reload, something like your page number), then call this within any controller method:

$stateParams.page = 1;
$state.reload();

You might need a GLOBAL TEMPORARY TABLE.

In Oracle these are created once and then when invoked the data is private to your session.

Oracle Documentation Link

Try something like this...

CREATE GLOBAL TEMPORARY TABLE temp_number
   ( number_column   NUMBER( 10, 0 )
   )
   ON COMMIT DELETE ROWS;

BEGIN 
   INSERT INTO temp_number
      ( number_column )
      ( select distinct sgbstdn_pidm 
          from sgbstdn 
         where sgbstdn_majr_code_1 = 'HS04' 
           and sgbstdn_program_1 = 'HSCOMPH' 
      ); 

    FOR pidms_rec IN ( SELECT number_column FROM temp_number )
    LOOP 
        -- Do something here
        NULL; 
    END LOOP; 
END; 
/

You need to wait for the emulator to full start - takes a few minutes. Once it is fully started (UI on the emulator will change), it should work.

You will need to restart the app after the emulator is running and choose the running emulator when prompted.

In case you are getting this in the eclipse IDE, even after setting the parameters --launcher.XXMaxPermSize, -XX:MaxPermSize, etc, still if you are getting the same error, it most likely is that the eclipse is using a buggy version of JRE which would have been installed by some third party applications and set to default. These buggy versions do not pick up the PermSize parameters and so no matter whatever you set, you still keep getting these memory errors. So, in your eclipse.ini add the following parameters:

-vm <path to the right JRE directory>/<name of javaw executable>

Also make sure you set the default JRE in the preferences in the eclipse to the correct version of java.

I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install. When I changed to the directory that had my makefile it worked.

So possibly you aren't in the right directory.

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

From the Java EE documentation:

public abstract boolean unique

(Optional) Whether the property is a unique key. This is a shortcut for the UniqueConstraint annotation at the table level and is useful for when the unique key constraint is only a single field. This constraint applies in addition to any constraint entailed by primary key mapping and to constraints specified at the table level.

See doc

You can avoid a useless use of cat and handle mismatched quotes better with this:

$ read -r -d '' VAR <<'EOF'
abc'asdf"
$(dont-execute-this)
foo"bar"''
EOF

If you don't quote the variable when you echo it, newlines are lost. Quoting it preserves them:

$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If you want to use indentation for readability in the source code, use a dash after the less-thans. The indentation must be done using only tabs (no spaces).

$ read -r -d '' VAR <<-'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
    EOF
$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If, instead, you want to preserve the tabs in the contents of the resulting variable, you need to remove tab from IFS. The terminal marker for the here doc (EOF) must not be indented.

$ IFS='' read -r -d '' VAR <<'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
EOF
$ echo "$VAR"
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''

Tabs can be inserted at the command line by pressing Ctrl-V Tab. If you are using an editor, depending on which one, that may also work or you may have to turn off the feature that automatically converts tabs to spaces.

It seems the docs/tool have been updated and you can now add the image tag to your script. This was successful for me.

Example:

This could be a bit tricky in the most general case.

On the face of it, InetAddress.getLocalHost() should give you the IP address of this host. The problem is that a host could have lots of network interfaces, and an interface could be bound to more than one IP address. And to top that, not all IP addresses will be reachable outside of your machine or your LAN. For example, they could be IP addresses for virtual network devices, private network IP addresses, and so on.

What this means is that the IP address returned by InetAddress.getLocalHost() might not be the right one to use.

How can you deal with this?

• One approach is to use NetworkInterface.getNetworkInterfaces() to get all of the known network interfaces on the host, and then iterate over each NI's addresses.
• Another approach is to (somehow) get the externally advertized FQDN for the host, and use InetAddress.getByName() to look up the primary IP address. (But how do you get it, and how do you deal with a DNS-based load balancer?)
• A variation of the previous is to get the preferred FQDN from a config file or a command line parameter.
• Another variation is to get the preferred IP address from a config file or a command line parameter.

In summary, InetAddress.getLocalHost() will typically work, but you may need to provide an alternative method for the cases where your code is run in an environment with "complicated" networking.

I am able to get all the IP addresses associated all Network Interfaces, but how do i distinguish them?

• Any address in the range 127.xxx.xxx.xxx is a "loopback" address. It is only visible to "this" host.
• Any address in the range 192.168.xxx.xxx is a private (aka site local) IP address. These are reserved for use within an organization. The same applies to 10.xxx.xxx.xxx addresses, and 172.16.xxx.xxx through 172.31.xxx.xxx.
• Addresses in the range 169.254.xxx.xxx are link local IP addresses. These are reserved for use on a single network segment.
• Addresses in the range 224.xxx.xxx.xxx through 239.xxx.xxx.xxx are multicast addresses.
• The address 255.255.255.255 is the broadcast address.
• Anything else should be a valid public point-to-point IPv4 address.

In fact, the InetAddress API provides methods for testing for loopback, link local, site local, multicast and broadcast addresses. You can use these to sort out which of the IP addresses you get back is most appropriate.

Appending to and copying slices

The variadic function append appends zero or more values x to s of type S, which must be a slice type, and returns the resulting slice, also of type S. The values x are passed to a parameter of type ...T where T is the element type of S and the respective parameter passing rules apply. As a special case, append also accepts a first argument assignable to type []byte with a second argument of string type followed by .... This form appends the bytes of the string.

append(s S, x ...T) S  // T is the element type of S

s0 := []int{0, 0}
s1 := append(s0, 2)        // append a single element     s1 == []int{0, 0, 2}
s2 := append(s1, 3, 5, 7)  // append multiple elements    s2 == []int{0, 0, 2, 3, 5, 7}
s3 := append(s2, s0...)    // append a slice              s3 == []int{0, 0, 2, 3, 5, 7, 0, 0}

Passing arguments to ... parameters

If f is variadic with final parameter type ...T, then within the function the argument is equivalent to a parameter of type []T. At each call of f, the argument passed to the final parameter is a new slice of type []T whose successive elements are the actual arguments, which all must be assignable to the type T. The length of the slice is therefore the number of arguments bound to the final parameter and may differ for each call site.

The answer to your question is example s3 := append(s2, s0...) in the Go Programming Language Specification. For example,

s := append([]int{1, 2}, []int{3, 4}...)

How was the package originally installed? If it was via apt, you could just be able to do apt-get remove python-m2crypto

If you installed it via easy_install, I'm pretty sure the only way is to just trash the files under lib, shared, etc..

My recommendation in the future? Use something like pip to install your packages. Furthermore, you could look up into something called virtualenv so your packages are stored on a per-environment basis, rather than solely on root.

With pip, it's pretty easy:

pip install m2crypto

But you can also install from git, svn, etc repos with the right address. This is all explained in the pip documentation

I found a function called sleep function on the internet and don't know who made it. Here it is.

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

sleep(2000);

First of all i say that you should google this as it is defined in detail in many places

Local
These variables only exist inside the specific function that creates them. They are unknown to other functions and to the main program. As such, they are normally implemented using a stack. Local variables cease to exist once the function that created them is completed. They are recreated each time a function is executed or called.

Global
These variables can be accessed (ie known) by any function comprising the program. They are implemented by associating memory locations with variable names. They do not get recreated if the function is recalled.

/* Demonstrating Global variables  */
    #include <stdio.h>
    int add_numbers( void );                /* ANSI function prototype */

    /* These are global variables and can be accessed by functions from this point on */
    int  value1, value2, value3;

    int add_numbers( void )
    {
        auto int result;
        result = value1 + value2 + value3;
        return result;
    }

    main()
    {
        auto int result;
        value1 = 10;
        value2 = 20;
        value3 = 30;        
        result = add_numbers();
        printf("The sum of %d + %d + %d is %d\n",
            value1, value2, value3, final_result);
    }


    Sample Program Output
    The sum of 10 + 20 + 30 is 60

The scope of global variables can be restricted by carefully placing the declaration. They are visible from the declaration until the end of the current source file.

#include <stdio.h>
void no_access( void ); /* ANSI function prototype */
void all_access( void );

static int n2;      /* n2 is known from this point onwards */

void no_access( void )
{
    n1 = 10;        /* illegal, n1 not yet known */
    n2 = 5;         /* valid */
}

static int n1;      /* n1 is known from this point onwards */

void all_access( void )
{
    n1 = 10;        /* valid */
    n2 = 3;         /* valid */
}

Static:
Static object is an object that persists from the time it's constructed until the end of the program. So, stack and heap objects are excluded. But global objects, objects at namespace scope, objects declared static inside classes/functions, and objects declared at file scope are included in static objects. Static objects are destroyed when the program stops running.
I suggest you to see this tutorial list

AUTO:
C, C++

(Called automatic variables.)

All variables declared within a block of code are automatic by default, but this can be made explicit with the auto keyword.[note 1] An uninitialized automatic variable has an undefined value until it is assigned a valid value of its type.[1]

Using the storage class register instead of auto is a hint to the compiler to cache the variable in a processor register. Other than not allowing the referencing operator (&) to be used on the variable or any of its subcomponents, the compiler is free to ignore the hint.

In C++, the constructor of automatic variables is called when the execution reaches the place of declaration. The destructor is called when it reaches the end of the given program block (program blocks are surrounded by curly brackets). This feature is often used to manage resource allocation and deallocation, like opening and then automatically closing files or freeing up memory.SEE WIKIPEDIA

This should work for all elements regardless of when they are generated.

if($('some_element').length == 0) {
}

write your code in the ajax callback functions and it should work fine.

To clarify the last post:

The VBoxManage command is:

VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME> 1

print date('H:i');

You have to set the correct timezone in php.ini .

Look for these lines:

[Date]

; Defines the default timezone used by the date functions

;date.timezone =

It will be something like :

date.timezone ="Europe/Lisbon"

Don't forget to restart your webserver.

Services are required to connect to the Service Control Manager and provide feedback at start up (ie. tell SCM 'I'm alive!'). That's why C# application have a different project template for services. You have two alternatives:

• wrapp your exe on srvany.exe, as described in KB How To Create a User-Defined Service
• have your C# app detect when is launched as a service (eg. command line param) and switch control to a class that inherits from ServiceBase and properly implements a service.

You could use POSIX [[:blank:]] to match a horizontal white-space character.

sed 's/[[:blank:]]\+/\n/g' file

or you may use [[:space:]] instead of [[:blank:]] also.

Example:

$ echo 'this  is a sentence' | sed 's/[[:blank:]]\+/\n/g'
this
is
a
sentence

I suggest

l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)

Check this demo.

Put the default value in single quote and it will work as intended. An example of migration:

$table->increments('id');
            $table->string('name');
            $table->string('url');
            $table->string('country');
            $table->tinyInteger('status')->default('1');
            $table->timestamps();

EDIT : in your case ->default('100.0');

$Group is an object, but you will actually need to check if $Group.samaccountname.StartsWith("string").

Change $Group.StartsWith("S_G_") to $Group.samaccountname.StartsWith("S_G_").

The error message is due to the call not going through the Request facade.

Change

use Illuminate\Http\Request;

To

use Request;

and it should start working.

In the config/app.php file, you can find a list of the class aliases. There, you will see that the base class Request has been aliased to the Illuminate\Support\Facades\Request class. Because of this, to use the Request facade in a namespaced file, you need to specify to use the base class: use Request;.

Edit

Since this question seems to get some traffic, I wanted to update the answer a little bit since Laravel 5 was officially released.

While the above is still technically correct and will work, the use Illuminate\Http\Request; statement is included in the new Controller template to help push developers in the direction of using dependency injection versus relying on the Facade.

When injecting the Request object into the constructor (or methods, as available in Laravel 5), it is the Illuminate\Http\Request object that should be injected, and not the Request facade.

So, instead of changing the Controller template to work with the Request facade, it is better recommended to work with the given Controller template and move towards using dependency injection (via constructor or methods).

Example via method

<?php namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class UserController extends Controller {

    /**
     * Store a newly created resource in storage.
     *
     * @param  Illuminate\Http\Request  $request
     * @return Response
     */
    public function store(Request $request) {
        $name = $request->input('name');
    }
}

Example via constructor

<?php namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class UserController extends Controller {

    protected $request;

    public function __construct(Request $request) {
        $this->request = $request;
    }

    /**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store() {
        $name = $this->request->input('name');
    }
}

In Java, a String is a reference to heap-allocated storage. Returning "ans" only returns the reference so there is no need for stack-allocated storage. In fact, there is no way in Java to allocate objects in stack storage.

I would change to this, though. You don't need "ans" at all.

return String.format("%d:%d", mins, secs);

I think there will be different ways to select a Date for different Date picker formats. For a Date Picker where you need to select a year and month from a dropdown and then pick/click a Date, I wrote the following code.

private void setupDate(WebDriver driver, String csvRow) throws Exception {
    String date[] = (csvRow).split("-");
    driver.findElement(By.id("flddateanchor")).click();
    new Select(driver.findElement(By
            .cssSelector("select.ui-datepicker-year")))
            .selectByVisibleText(date[0]);
    Thread.sleep(1000);
    new Select(driver.findElement(By
            .cssSelector("select.ui-datepicker-month")))
            .selectByVisibleText(date[1]);
    Thread.sleep(1000);
    driver.findElement(By.linkText(date[2])).click();
    Thread.sleep(1000);
}

I got the cssSelector part by the Selenium Firefox IDE. Also, my Date(csvRow) is in (2015-03-31) format.

Hope it helps.

For .NET Core, add System.Configuration.ConfigurationManager from NuGet manager.
And read appSetting from App.config

<appSettings>
  <add key="appSetting1" value="1000" />
</appSettings>

Add System.Configuration.ConfigurationManager from NuGet Manager

ConfigurationManager.AppSettings.Get("appSetting1")

You have to loop through every cell in the range "D3:D6" and construct your To string. Simply assigning it to a variant will not solve the purpose. EmailTo becomes an array if you assign the range directly to it. You can do this as well but then you will have to loop through the array to create your To string

Is this what you are trying? (TRIED AND TESTED)

Option Explicit

Sub Mail_workbook_Outlook_1()
     'Working in 2000-2010
     'This example send the last saved version of the Activeworkbook
    Dim OutApp As Object
    Dim OutMail As Object
    Dim emailRng As Range, cl As Range
    Dim sTo As String

    Set emailRng = Worksheets("Selections").Range("D3:D6")

    For Each cl In emailRng 
        sTo = sTo & ";" & cl.Value
    Next

    sTo = Mid(sTo, 2)

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    On Error Resume Next
    With OutMail
        .To = sTo
        .CC = "[email protected];[email protected]"
        .BCC = ""
        .Subject = "RMA #" & Worksheets("RMA").Range("E1")
        .Body = "Attached to this email is RMA #" & _
        Worksheets("RMA").Range("E1") & _
        ". Please follow the instructions for your department included in this form."
        .Attachments.Add ActiveWorkbook.FullName
         'You can add other files also like this
         '.Attachments.Add ("C:\test.txt")

        .Display

Use the object syntax.

v-bind:class="{'fa-checkbox-marked': content['cravings'],  'fa-checkbox-blank-outline': !content['cravings']}"

When the object gets more complicated, extract it into a method.

v-bind:class="getClass()"

methods:{
    getClass(){
        return {
            'fa-checkbox-marked': this.content['cravings'],  
            'fa-checkbox-blank-outline': !this.content['cravings']}
    }
}

Finally, you could make this work for any content property like this.

v-bind:class="getClass('cravings')"

methods:{
  getClass(property){
    return {
      'fa-checkbox-marked': this.content[property],
      'fa-checkbox-blank-outline': !this.content[property]
    }
  }
}

In httpd.conf file you need to remove #

#LoadModule rewrite_module modules/mod_rewrite.so

after removing # line will look like this:

LoadModule rewrite_module modules/mod_rewrite.so

And Apache restart

Another approach by iterating the array from outside to inside and reduce the matrix by mapping inner values.

const_x000D_
    transpose = array => array.reduce((r, a) => a.map((v, i) => [...(r[i] || []), v]), []),_x000D_
    matrix = [[1, 2, 3], [1, 2, 3], [1, 2, 3]];_x000D_
_x000D_
console.log(transpose(matrix));

@inmyth's answer is correct, just modify the code a bit, to handle empty list.

public class NewsAdapter extends RecyclerView.Adapter<...> {    
    ...
    private static List mFeedsList;
    ...    
    public void swap(List list){
            if (mFeedsList != null) {
                mFeedsList.clear();
                mFeedsList.addAll(list);
            }
            else {
                mFeedsList = list;
            }
            notifyDataSetChanged();
    }

I am using Retrofit to fetch the list, on Retrofit's onResponse() use,

adapter.swap(feedList);

Make sure /webapps/ROOT file is there and it has all the icons, WEB-INF, and index.jsp is in the folder.

When you startup Tomcat, it will run this code in <Tomcat-Directory>/conf/web.xml directory:

<welcome-file-list>
   <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

The location of index.jsp is in <Tomcat-Directory>/webapps/ROOT/index.jsp

Also, try running tomcat from the /bin directory using ./catalina.sh start instead of ./startup.sh. For some reason, ./startup.sh isn't as reliable.

We can get the UTC/GMT time stamp from the given date.

/**
 * Get the time stamp in GMT/UTC by passing the valid time (dd-MM-yyyy HH:mm:ss)
 */
public static long getGMTTimeStampFromDate(String datetime) {
    long timeStamp = 0;
    Date localTime = new Date();

    String format = "dd-MM-yyyy HH:mm:ss";
    SimpleDateFormat sdfLocalFormat = new SimpleDateFormat(format);
    sdfLocalFormat.setTimeZone(TimeZone.getDefault());

    try {

        localTime = (Date) sdfLocalFormat.parse(datetime); 

        Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("UTC"),
                Locale.getDefault());
        TimeZone tz = cal.getTimeZone();

        cal.setTime(localTime);

        timeStamp = (localTime.getTime()/1000);
        Log.d("GMT TimeStamp: ", " Date TimegmtTime: " + datetime
                + ", GMT TimeStamp : " + localTime.getTime());

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return timeStamp;

}

It will return the UTC time based on passed date.

• We can do reverse like UTC time stamp to current date and time(vice versa)

      public static String getLocalTimeFromGMT(long gmtTimeStamp) {
               try{
                      Calendar calendar = Calendar.getInstance();
                      TimeZone tz = TimeZone.getDefault();
                      calendar.setTimeInMillis(gmtTimeStamp * 1000);
      //              calendar.add(Calendar.MILLISECOND, tz.getOffset(calendar.getTimeInMillis())); 
                      SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
                      Date currenTimeZone = (Date) calendar.getTime();
                      return sdf.format(currenTimeZone);
                  }catch (Exception e) {
                  }
                  return "";  
              }
  

I hope this will help others. Thanks!!

There are two obvious issues with the set literal syntax:

my_set = {'foo', 'bar', 'baz'}

1. It's not available before Python 2.7

2. There's no way to express an empty set using that syntax (using {} creates an empty dict)

Those may or may not be important to you.

The section of the docs outlining this syntax is here.

when your add permission in manifest then in eclipse go to project and clic

Two-stage authentication is not supported with IIS7 Integrated mode. Authentication is now modularized, so rather than IIS performing authentication followed by asp.net performing authentication, it all happens at the same time.

You can either:

1. Change the app domain to be in IIS6 classic mode...
2. Follow this example (old link) of how to fake two-stage authentication with IIS7 integrated mode.
3. Use Helicon Ape and mod_auth to provide basic authentication

It makes it easier for you, and generates the correct sizes directly

I know you may have found the answer , but if there were people looking for it in the future, they may find the solution.OK, straight to the point ,I had a similar problem like this one. When you are usually staring to use this library (selenium webdriver ) one thing that can make you angry is not to know how to use the library " import time " that is very import for breaking this type of " barrier ".

Follow the code snippet below:

Well, my solution was simple and objective. Remembering that you must wait for the element to be clickable (interactable), which is, first use the technique of searching for element by xpath.

buttonNoInteractable = browser.find_element_by_xpath('/html/body/div[2]/div/div/div[2]/div/div/div[2]/div/table[2]/thead/tr/th[2]/input')

buttonNoIteractable.click() time.sleep(10)

Or it can be by class name. Use the amount of seconds you need, if you have a slow connection, put it in 30 seconds, or if it is fast, a few seconds less is enough, for example "time.sleep (10)".

As I said, for me this solution worked very well using python.

send = browser.find_element_by_name('stacks') send.click()

Currently there is no way to do this correctly in a deterministic way, with fixed-size images such as JPEGs or PNG files.

To resize an image proportionally, you have to set either the height or width to "100%", but not both. If you set both to "100%", your image will be stretched.

Choosing whether to do height or width depends on your image and container dimensions:

1. If your image and container are both "portrait shaped" or both "landscape shaped" (taller than they are wide, or wider than they are tall, respectively), then it doesn't matter which of height or width are "%100".
2. If your image is portrait, and your container is landscape, you must set height="100%" on the image.
3. If your image is landscape, and your container is portrait, you must set width="100%" on the image.

If your image is an SVG, which is a variable-sized vector image format, you can have the expansion to fit the container happen automatically.

You just have to ensure that the SVG file has none of these properties set in the <svg> tag:

height
width
viewbox

Most vector drawing programs out there will set these properties when exporting an SVG file, so you will have to manually edit your file every time you export, or write a script to do it.

The way i will do this using jquery is something like this..

var targetedchild = $("#test").children().find("span.four");

In C++11 at least, when the expression used to initialize a local static variable is not a 'constexpr' (cannot be evaluated by the compiler), then initialization must happen during the first call to the function. The simplest example is to directly use a parameter to intialize the local static variable. Thus the compiler must emit code to guess whether the call is the first one or not, which in turn requires a local boolean variable. I've compiled such example and checked this is true by seeing the assembly code. The example can be like this:

void f( int p )
{
  static const int first_p = p ;
  cout << "first p == " << p << endl ;
}

void main()
{
   f(1); f(2); f(3);
}

of course, when the expresion is 'constexpr', then this is not required and the variable can be initialized on program load by using a value stored by the compiler in the output assembly code.

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

There's a new library for traversing JSON data with JavaScript that supports many different use cases.

It provides the path of each node, too.

Another (async) approach, using Identity's UserManager and SigninManager to reflect the change in the Identity cookie (and to optionally remove claims from db table AspNetUserClaims):

// Get User and a claims-based identity
ApplicationUser user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
var Identity = new ClaimsIdentity(User.Identity);

// Remove existing claim and replace with a new value
await UserManager.RemoveClaimAsync(user.Id, Identity.FindFirst("AccountNo"));
await UserManager.AddClaimAsync(user.Id, new Claim("AccountNo", value));

// Re-Signin User to reflect the change in the Identity cookie
await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);

// [optional] remove claims from claims table dbo.AspNetUserClaims, if not needed
var userClaims = UserManager.GetClaims(user.Id);
if (userClaims.Any())
{
  foreach (var item in userClaims)
  {
    UserManager.RemoveClaim(user.Id, item);
  }
}

To make the scripts compatible with Python2 and 3 i use :

Response.Redirect(Request.Url.ToString());

I'd like to add that div-based layouts are easer to mantain, evolve, and refactor. Just some changes in the CSS to reorder elements and it is done. From my experience, redesign a layout that uses tables is a nightmare (more if there are nested tables).

Your code also has a meaning from a semantic point of view.

For swift 2 :

self.title = "Your Title"

var homeButton : UIBarButtonItem = UIBarButtonItem(title: "LeftButtonTitle", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("yourMethod"))

var logButton : UIBarButtonItem = UIBarButtonItem(title: "RigthButtonTitle", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("yourMethod"))

self.navigationItem.leftBarButtonItem = homeButton
self.navigationItem.rightBarButtonItem = logButton

I wanted to be able to find and replace text but also include matched groups in the content I insert. I wrote this short script to do that:

https://gist.github.com/turtlemonvh/0743a1c63d1d27df3f17

The key component of that is something that looks like like this:

print(re.sub(pattern, template, text).rstrip("\n"))

Here's an example of how that works:

# Find everything that looks like 'dog' or 'cat' followed by a space and a number
pattern = "((cat|dog) (\d+))"

# Replace with 'turtle' and the number. '3' because the number is the 3rd matched group.
# The double '\' is needed because you need to escape '\' when running this in a python shell
template = "turtle \\3"

# The text to operate on
text = "cat 976 is my favorite"

Calling the above function with this yields:

turtle 976 is my favorite

Jupyter has its own PATH variable, JUPYTER_PATH.

Adding this line to the .bashrc file worked for me:

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

<video id="bgVideo" autoplay poster="videos/poster.png">
    <source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
    <source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
    <source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>    
</video>

<img id="bgImg" src="videos/poster.png" />

<!-- This image stretches exactly to the browser width/height and lies behind the video-->

<div id="bodyDummy">

Put all your content inside the bodydummy-div and put the z-indexes correctly in CSS like this:

#bgImg{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 1;
    width: 100%;
    height: 100%;
}

#bgVideo{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 2;
    width: 100%;
    height: 100%;
}

#bodyDummy{ 
    position: absolute;
    top: 0;
    left: 0;
    z-index: 3;
    overflow: auto;
    width: 100%;
    height: 100%;
}

Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.

Try this simple code.

1. Components side code: to get both body and header property. Here there's a token in body and Authorization in the header.

loginUser() {
    this.userService.loginTest(this.loginCred).
    subscribe(res => {
        let output1 = res;
        console.log(output1.body.token);
        console.log(output1.headers.get('Authorization'));
    })
}

2. Service side code: sending login data in the body and observe the response in Observable any which be subscribed in the component side.

loginTest(loginCred: LoginParams): Observable<any> {
    const header1= {'Content-Type':'application/json',};
    const body =  JSON.stringify(loginCred);
    return this.http.post<any>(this.baseURL+'signin',body,{
        headers: header1,
        observe: 'response',
        responseType: 'json'
    });
}

To be consistent with the type I would use:

mylist = list(set(mylist))

if you just want to save and load a list try Pickle

Pickle saving:

with open("yourFile","wb")as file:
 pickle.dump(YourList,file)

and loading:

with open("yourFile","rb")as file:
 YourList=pickle.load(file)

You can use File.Exists to check if the file exists and create it using File.Create if required. Make sure you check if you have access to create files at that location.

Once you are certain that the file exists, you can write to it safely. Though as a precaution, you should put your code into a try...catch block and catch for the exceptions that function is likely to raise if things don't go exactly as planned.

Additional information for basic file I/O concepts.

REGEXP_LIKE(column, '^[[:digit:]]+$')

returns TRUE if column holds only numeric characters

You can use the minDate property, like this:

$("input.DateFrom").datepicker({
    changeMonth: true, 
    changeYear: true, 
    dateFormat: 'yy-mm-dd',
    minDate: 0, // 0 days offset = today
    maxDate: 'today',
    onSelect: function(dateText) {
        $sD = new Date(dateText);
        $("input#DateTo").datepicker('option', 'minDate', min);
    }
});

You can also specify a date, like this:

minDate: new Date(), // = today

If you want to use glyph icons with bootstrap 2.3.2, Add the font files from bootstrap 3 to your project folder then copy this to your css file

 @font-face {
  font-family: 'Glyphicons Halflings';
  src: url('../fonts/glyphicons-halflings-regular.eot');
  src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

Semantically this feels like the correct behaviour

I'd be asking myself "Why do I need to submit this value?"

If you have a disabled input on a form, then presumably you do not want the user changing the value directly

Any value that is displayed in a disabled input should either be

1. output from a value on the server that produced the form, or
2. if the form is dynamic, be calculable from the other inputs on the form

Assuming that the server processing the form is the same as the server serving it, all the information to reproduce the values of the disabled inputs should be available at processing

In fact, to preserve data integrity - even if the value of the disabled input was sent to the processing server, you should really be validating it. This validation would require the same level of information as you would need to reproduce the values anyway!

I'd almost argue that read-only inputs shouldn't be sent in the request either

Happy to be corrected, but all the use cases I can think of where read-only/disabled inputs need to be submitted are really just styling issues in disguise

Building on Joe's idea, here is a version which will build its own (.js) helper and supporting time as well:

@echo off

set _TMP=%TEMP%\_datetime.tmp

echo var date = new Date(), string, tmp;> "%_TMP%"
echo tmp = ^"000^" + date.getFullYear(); string = tmp.substr(tmp.length - 4);>> "%_TMP%"
echo tmp = ^"0^" + (date.getMonth() + 1); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getDate(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getHours(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getMinutes(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo tmp = ^"0^" + date.getSeconds(); string += tmp.substr(tmp.length - 2);>> "%_TMP%"
echo WScript.Echo(string);>> "%_TMP%"

for /f %%i in ('cscript //nologo /e:jscript "%_TMP%"') do set _DATETIME=%%i

del "%_TMP%"

echo YYYYMMDDhhmmss: %_DATETIME%
echo YYYY: %_DATETIME:~0,4%
echo YYYYMM: %_DATETIME:~0,6%
echo YYYYMMDD: %_DATETIME:~0,8%
echo hhmm: %_DATETIME:~8,4%
echo hhmmss: %_DATETIME:~8,6%

Another solution that may work for people, since none of the text options worked for me:

1. Replace the content of .gitattributes with a single line: * binary. This tells git to treat every file as a binary file that it can't do anything with.
2. Check that message for the offending files is gone; if it's not you can git checkout -- <files> to restore them to the repository version
3. git checkout -- .gitattributes to restore the .gitattributes file to its initial state
4. Check that the files are still not marked as changed.

Follow the steps:

1. Go psql shell
2. \c db_name
3. \i path_of_dump [eg:-C:/db_name.pgsql]

Here is my take: these functions convert a UTF8 string to a proper HEX without the extra zeroes padding. A real UTF8 string has characters with 1, 2, 3 and 4 bytes length.

While working on this I found a couple key things that solved my problems:

1. str.split('') doesn't handle multi-byte characters like emojis correctly. The proper/modern way to handle this is with Array.from(str)
2. encodeURIComponent() and decodeURIComponent() are great tools to convert between string and hex. They are pretty standard, they handle UTF8 correctly.
3. (Most) ASCII characters (codes 0 - 127) don't get URI encoded, so they need to handled separately. But c.charCodeAt(0).toString(16) works perfectly for those

    function utf8ToHex(str) {
      return Array.from(str).map(c => 
        c.charCodeAt(0) < 128 ? c.charCodeAt(0).toString(16) : 
        encodeURIComponent(c).replace(/\%/g,'').toLowerCase()
      ).join('');
    },
    function hexToUtf8: function(hex) {
      return decodeURIComponent('%' + hex.match(/.{1,2}/g).join('%'));
    }

My problem did not go away with just reinstalling the 2015 vc redistributables. But I was able to find the error using the same process as in the excellent blog post by Ezh (and thanks to Google Translate for making me able to read it).

In my case it was msvcp140.dll that was installed as a 64bit version in the Windows/SysWOW64 folder. Just uninstalling the redistributables did not remove the file, so I had to delete it manually. Then I was able to install the x86 redistributables again, which installed a correct version of the dll file. And, voilà, the installation of VS2015 finished without errors.

We often run into this where we want to include a the index value and first and last indicators in a list without creating a new object. This allows you to know the position of the item in your list, enumeration, etc. without having to modify the existing class and then knowing whether you're at the first item in the list or the last.

foreach (Item item in this.Items
    .Select((x, i) => {
    x.ListIndex = i;
    x.IsFirst = i == 0;
    x.IsLast = i == this.Items.Count-1;
    return x;
}))

You can simply extend any class by using:

public abstract class IteratorExtender {
    public int ListIndex { get; set; }
    public bool IsFirst { get; set; } 
    public bool IsLast { get; set; } 
}

public class Item : IteratorExtender {}

One way is to: (Assumes index column begins at A1)

MsgBox Range("A1").End(xlDown).Row

Which is looking for the 1st unoccupied cell downwards from A1 and showing you its ordinal row number.

You can select the next empty cell with:

Range("A1").End(xlDown).Offset(1, 0).Select

If you need the end of a dataset (including blanks), try: Range("A:A").SpecialCells(xlLastCell).Row

@fthiella 's solution is very elegant.

If in future you want show more than user_id you could use joins, and there in one line could be all data you need.

If you want to use AND conditions, and the conditions are in multiple lines in your table, you can use JOINS example:

SELECT `w_name`.`user_id` 
     FROM `wp_usermeta` as `w_name`
     JOIN `wp_usermeta` as `w_year` ON `w_name`.`user_id`=`w_year`.`user_id` 
          AND `w_name`.`meta_key` = 'first_name' 
          AND `w_year`.`meta_key` = 'yearofpassing' 
     JOIN `wp_usermeta` as `w_city` ON `w_name`.`user_id`=`w_city`.user_id 
          AND `w_city`.`meta_key` = 'u_city'
     JOIN `wp_usermeta` as `w_course` ON `w_name`.`user_id`=`w_course`.`user_id` 
          AND `w_course`.`meta_key` = 'us_course'
     WHERE 
         `w_name`.`meta_value` = '$us_name' AND         
         `w_year`.meta_value   = '$us_yearselect' AND 
         `w_city`.`meta_value` = '$us_reg' AND 
         `w_course`.`meta_value` = '$us_course'

Other thing: Recommend to use prepared statements, because mysql_* functions is not SQL injection save, and will be deprecated. If you want to change your code the less as possible, you can use mysqli_ functions: http://php.net/manual/en/book.mysqli.php

Recommendation:

Use indexes in this table. user_id highly recommend to be and index, and recommend to be the meta_key AND meta_value too, for faster run of query.

The explain:

If you use AND you 'connect' the conditions for one line. So if you want AND condition for multiple lines, first you must create one line from multiple lines, like this.

Tests: Table Data:

          PRIMARY                 INDEX
      int       varchar(255)    varchar(255)
       /                \           |
  +---------+---------------+-----------+
  | user_id | meta_key      | meta_value|
  +---------+---------------+-----------+
  | 1       | first_name    | Kovge     |
  +---------+---------------+-----------+
  | 1       | yearofpassing | 2012      |
  +---------+---------------+-----------+
  | 1       | u_city        | GaPa      |
  +---------+---------------+-----------+
  | 1       | us_course     | PHP       |
  +---------+---------------+-----------+

The result of Query with $us_name='Kovge' $us_yearselect='2012' $us_reg='GaPa', $us_course='PHP':

 +---------+
 | user_id |
 +---------+
 | 1       |
 +---------+

So it should works.

You Write Two Function

    //When Expression is Number
    public static double? isNull(double? Expression, double? Value)
    {
        if (Expression ==null)
        {
            return Value;
        }
        else
        {
            return Expression;
        }
    }


    //When Expression is string (Can not send Null value in string Expression
    public static string isEmpty(string Expression, string Value)
    {
        if (Expression == "")
        {
            return Value;
        }
        else
        {
            return Expression;
        }
    }

They Work Very Well

Use a date not a datetime if you dont care about the time.

>>> now = datetime.now()
>>> now.date()
datetime.date(2011, 3, 29)

You can update a datetime like this:

>>> now.replace(minute=0, hour=0, second=0, microsecond=0)
datetime.datetime(2011, 3, 29, 0, 0)

Using Powershell you can do this:

# Checks for updates and changes in working copy.
# Regex: Excludes unmodified (first 7 columns blank). To exclude more add criteria to negative look ahead.
# -u: svn gets updates
$regex = '^(?!\s{7}).{7}\s+(.+)';
svn status -u | %{ if($_ -match $regex){ $_ } };

This will include property changes. These show in column 2. It will also catch other differences in files that show in columns 3-7.

Sources:

• svn status: http://svnbook.red-bean.com/en/1.8/svn.ref.svn.c.status.html

• Regex to match results of svn status: Using powershell and svn to delete unversioned files

To distribute your app over-the-air (OTA, this means without using TestFlight or the official App Store), you may need to create 3 different files, namely:

• The .ipa file (using an ad-hoc provisioning profile)
• index.html
• manifest.plist

You can use Beta Builder to generate these files:

1. Archive your build.
2. Save the .ipa on the Desktop.
3. Download a small utility Beta Builder from here. This does most of the required task.
4. Open the tool and select your .ipa file, then provide the path you will be placing the build on https://myWeb.com/MY_TEST_APP in the beta builder.
5. Generate all the files.
6. Now upload index.html, your_App.ipa, & manifest.plist to your server path https://myWeb.com/MY_TEST_APP
7. Now share the link of index.html. Once you open this file, you will be asked to Tap on install.
8. It will install your_App.ipa on your device.

You can also do this more manually.

index.html

manifest.plist

<?xml version="1.0" encoding="UTF-8"?>

            </dict>
        </dict>
    </array>
</dict>
</plist>

If the app refuses to install or run, you may need to check the following items:

• The provisioning profile you've used when compiling/archiving your app
• The URLs in both index.html and manifest.plist
• The plist file may possibly need to be hosted on an HTTPS server. You can use Dropbox for this if necessary.
• Your device UUIDs may need to be registered inside Apple Developer Center unless you have an Enterprise licence
• You may need to manually enable access to the app within Settings > Profiles

In reference to your comment after Ian Henry's answer, I'm not quite 100% sure I understand what you are asking.

If it is about getting double quote marks added into a string, you can concatenate the double quotes into your string, for example:

String theFirst = "Java Programming";
String ROM = "\"" + theFirst + "\"";

Or, if you want to do it with one String variable, it would be:

String ROM = "Java Programming";
ROM = "\"" + ROM + "\"";

Of course, this actually replaces the original ROM, since Java Strings are immutable.

If you are wanting to do something like turn the variable name into a String, you can't do that in Java, AFAIK.

The logging module has everything you could want. It may seem excessive at first, but only use the parts you need. I'd recommend using logging.basicConfig to toggle the logging level to stderr and the simple log methods, debug, info, warning, error and critical.

import logging, sys
logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)
logging.debug('A debug message!')
logging.info('We processed %d records', len(processed_records))

using System;
using System.Text.RegularExpressions;

private IEnumerable<string> GetSubStrings(string input, string start, string end)
{
    Regex r = new Regex(Regex.Escape(start) +`"(.*?)"`  + Regex.Escape(end));
    MatchCollection matches = r.Matches(input);
    foreach (Match match in matches)
    yield return match.Groups[1].Value;
}

Set it the same way you'd set the width of any other HTML element, with CSS:

audio { width: 200px; }

Note that audio is an inline element by default in Firefox, so you might also want to set it to display: block. Here's an example.

1: remove dropdown-trigger:

data-toggle="dropdown"

2: add this your css

.dropdown:hover .dropdown-menu {
    display: block;
}
.dropdown-menu {
    margin-top: 0px;
}

You can also use OPENROWSET to import excel file in sql server.

SELECT * INTO Your_Table FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
                        'Excel 12.0;Database=C:\temp\MySpreadsheet.xlsx',
                        'SELECT * FROM [Data$]')

Workflow example with GIT.

Git is extremely flexible and adapts good to any workflow, but not enforcing a particular workflow might have the negative effect of making it hard to understand what you can do with git beyond the linear "backup" workflow, and how useful branching can be for example.

This blog post explains nicely a very simple but effective workflow that is really easy to setup using git.

quoting from the blog post: We consider origin/master to be the main branch where the source code of HEAD always reflects a production-ready state:

The workflow has become popular enough to have made a project that implements this workflow: git-flow

Nice illustration of a simple workflow, where you make all your changes in develop, and only push to master when the code is in a production state:

Now let's say you want to work on a new feature, or on refactoring a module. You could create a new branch, what we could call a "feature" branch, something that will take some time and might break some code. Once your feature is "stable enough" and want to move it "closer" to production, you merge your feature branch into develop. When all the bugs are sorted out after the merge and your code passes all tests rock solid, you push your changes into master.

During all this process, you find a terrible security bug, that has to be fixed right away. You could have a branch called hotfixes, that make changes that are pushed quicker back into production than the normal "develop" branch.

Here you have an illustration of how this feature/hotfix/develop/production workflow might look like (well explained in the blog post, and I repeat, the blog post explains the whole process in a lot more detail and a lot better than I do.

How about filtering these errors ?

With the regex filter bellow, we can dismiss cast_sender.js errors :

^((?!cast_sender).)*$

Do not forget to check Regex box.
