To create a new Data source to SQL Server, do the following steps:

1. In host computer/server go to Sql server management studio --> open Security Section on left hand --> right click on Login, select New Login and then create a new account for your database which you want to connect to.

2. Check the TCP/IP Protocol is Enable. go to All programs --> Microsoft SQL server 2008 --> Configuration Tools --> open Sql server configuration manager. On the left hand select client protocols (based on your operating system 32/64 bit). On the right hand, check TCP/IP Protocol be Enabled.

3. In Remote computer/server, open Data source administrator. Control panel --> Administrative tools --> Data sources (ODBC).

4. In User DSN or System DSN , click Add button and select Sql Server driver and then press Finish.

5. Enter Name.

6. Enter Server, note that: if you want to enter host computer address, you should enter that`s IP address without "\\". eg. 192.168.1.5 and press Next.

7. Select With SQL Server authentication using a login ID and password entered by the user.

8. At the bellow enter your login ID and password which you created on first step. and then click Next.

9. If shown Database is your database, click Next and then Finish.

Add the useUnifiedTopology option and set it to true.

Set other 3 configuration of the mongoose.connect options which will deal with other remaining DeprecationWarning.

This configuration works for me!

const url = 'mongodb://localhost:27017/db_name';
mongoose.connect(
    url, 
    { 
        useNewUrlParser: true, 
        useUnifiedTopology: true,
        useCreateIndex: true,
        useFindAndModify: false
    }
)

This will solve 4 DeprecationWarning.

1. Current URL string parser is deprecated, and will be removed in a future version. To use the new parser, pass option { useNewUrlParser: true } to MongoClient.connect.
2. Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor.
3. Collection.ensureIndex is deprecated. Use createIndexes instead.
4. DeprecationWarning: Mongoose: findOneAndUpdate() and findOneAndDelete() without the useFindAndModify option set to false are deprecated. See: https://mongoosejs.com/docs/deprecations.html#-findandmodify-.

Hope it helps.

There are a bunch of different reasons for the "Too Many Connections" error.

Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html

Check your my.cnf file for "max_connections". If none exist try:

[mysqld]
set-variable=max_connections=250

However the default is 151, so you should be okay.

If you are on a shared host, it might be that other users are taking up too many connections.

Other problems to look out for is the use of persistent connections and running out of diskspace.

This is the initial database of the data source when you connect.

Edited for clarity:

If you have multiple databases in your SQL Server instance and you don't want to use the default database, you need some way to specify which one you are going to use.

put this line in parent construct : $this->load->database();

function  __construct() {
    parent::__construct();
    $this->load->library('lib_name');
    $model=array('model_name');
    $this->load->model($model);
    $this->load->database();
}

this way.. it should work..

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

You get this error when a datasource attempts to bind to data but cannot because it cannot find the connection string. In my experience, this is not usually due to an error in the web.config (though I am not 100% sure of this).

If you are programmatically assigning a datasource (such as a SqlDataSource) or creating a query (i.e. using a SqlConnection/SqlCommand combination), make sure you assigned it a ConnectionString.

var connection = new SqlConnection(ConfigurationManager.ConnectionStrings[nameOfString].ConnectionString);

If you are hooking up a databound element to a datasource (i.e. a GridView or ComboBox to a SqlDataSource), make sure the datasource is assigned to one of your connection strings.

Post your code (for the databound element and the web.config to be safe) and we can take a look at it.

EDIT: I think the problem is that you are trying to get the Connection String from the AppSettings area, and programmatically that is not where it exists. Try replacing that with ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString (if ConnectionString is the name of your connection string.)

DATABASE_URL=postgres://{user}:{password}@{hostname}:{port}/{database-name}

You might try turning off pooling, which is enabled by default. See this discussion for more information.

import pyodbc
pyodbc.pooling = False
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 

csr = conn.cursor()  
csr.close()
del csr

In PostgreSQL 9.6, there's a new option idle_in_transaction_session_timeout which should accomplish what you describe. You can set it using the SET command, e.g.:

SET SESSION idle_in_transaction_session_timeout = '5min';

I had a similar error with the inner exception as below:

operation is not valid for the state of the transaction

I could resolve it by enabling DTC security settings.

Go To Properties of DTC, under Security Tab, check the below

• Network DTC Access
• Allow RemoteClients
• Transaction Manager Communication
• Allow Inbound
• Allow Outbound

mongodb.com -> new project -> new cluster -> new collection -> connect -> IP address: 0.0.0.0/0 & db cred -> connect your application -> copy connection string and paste in .env file of your node app and make sure to replace "" with the actual password for the user and also replace "/test" with your db name

create new file .env

Like the other answers said, sp_reset_connection indicates that connection pool is being reused. Be aware of one particular consequence!

Jimmy Mays' MSDN Blog said:

sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.

UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.

ref: SQL Server: Isolation level leaks across pooled connections

Here is some additional information:

What does sp_reset_connection do?

Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.

sp_reset_connection resets the following aspects of a connection:

• All error states and numbers (like @@error)

• Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query

• Waits for any outstanding I/O operations that is outstanding

• Frees any held buffers on the server by the connection

• Unlocks any buffer resources that are used by the connection

• Releases all allocated memory owned by the connection

• Clears any work or temporary tables that are created by the connection

• Kills all global cursors owned by the connection

• Closes any open SQL-XML handles that are open

• Deletes any open SQL-XML related work tables

• Closes all system tables

• Closes all user tables

• Drops all temporary objects

• Aborts open transactions

• Defects from a distributed transaction when enlisted

• Decrements the reference count for users in current database which releases shared database locks

• Frees acquired locks

• Releases any acquired handles

• Resets all SET options to the default values

• Resets the @@rowcount value

• Resets the @@identity value

• Resets any session level trace options using dbcc traceon()

• Resets CONTEXT_INFO to NULL in SQL Server 2005 and newer _{[ not part of the original article ]}

sp_reset_connection will NOT reset:

• Security context, which is why connection pooling matches connections based on the exact connection string

• Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when sp_setapprole is executed.

Note: I am including the list here as I do not want it to be lost in the ever transient web.

If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.

Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.

If you want to audit a client application name along with each failed login, you can use an Extended Events session.

To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/

It can happen if you don't have enough privileges. Type su, enter root password and try again.

(sorry, this was a more generic answer about SQL backends--I hadn't read the answer about SQL Server 2005's WebServices feature. Although, this feature is still run over HTTP rather than more directly via sockets, so essentially they've built a mini web server into the database server, so this answer is still another route you could take.)

You can also connect directly using sockets (google "javascript sockets") and by directly at this point I mean using a Flash file for this purpose, although HTML5 has Web Sockets as part of the spec which I believe let you do the same thing.

Some people cite security issues, but if you designed your database permissions correctly you should theoretically be able to access the database from any front end, including OSQL, and not have a security breach. The security issue, then, would be if you weren't connecting via SSL.

Finally, though, I'm pretty sure this is all theoretical because I don't believe any JavaScript libraries exist for handling the communications protocols for SSL or SQL Server, so unless you're willing to figure these things out yourself it'd be better to go the route of having a web server and server-side scripting language in between the browser and the database.

Actually, it is best if you use a try-with-resources block and Java will close all of the connections for you when you exit the try block.

You should do this with any object that implements AutoClosable.

try (Connection connection = getDatabaseConnection(); Statement statement = connection.createStatement()) {
    String sqlToExecute = "SELECT * FROM persons";
    try (ResultSet resultSet = statement.execute(sqlToExecute)) {
        if (resultSet.next()) {
            System.out.println(resultSet.getString("name");
        }
    }
} catch (SQLException e) {
    System.out.println("Failed to select persons.");
}

The call to getDatabaseConnection is just made up. Replace it with a call that gets you a JDBC SQL connection or a connection from a pool.

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

If you're already logged into the command line client try this:

mysql> select user();

It will output something similar to this:

+----------------+
| user()         |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.41 sec)

In my example above, I was logged in as root from localhost.

To find port number and other interesting settings use this command:

mysql> show variables;

Here is an example:

MySqlConnection con = new MySqlConnection(
    "Server=ServerName;Database=DataBaseName;UID=username;Password=password");

MySqlCommand cmd = new MySqlCommand(
    " INSERT Into Test (lat, long) VALUES ('"+OSGconv.deciLat+"','"+
    OSGconv.deciLon+"')", con);

con.Open();
cmd.ExecuteNonQuery();
con.Close();

To fix this issue I just run one query in my mysql console.

For this login to mysql console using this

mysql -u {username} -p{password}

After this I just run one query as given below:-

ALTER user '{USERNAME}'@'localhost' identified with mysql_native_password by '{PASSWORD}';

when I run this query I got message that query executed. Then login to PHPMYADMIN with username/password.

You haven't created a user db. If its just a fresh install, the default user is postgres and the password should be blank. After you access it, you can create the users you need.

If you need to increase MySQL Connections without MySQL restart do like below

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL max_connections = 150;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 150   |
+-----------------+-------+
1 row in set (0.00 sec)

These settings will change at MySQL Restart.

For permanent changes add below line in my.cnf and restart MySQL

max_connections = 150

In the config file, change the "host" variable to point to the external server. The config file is called config.inc.php and it will be in the main phpMyAdmin folder. There should be a line like this:

$cfg['Servers'][$i]['host'] = 'localhost';

Just change localhost to your server's IP address.

Note: you may have to configure the external server to allow remote connections, but I've done this several times on shared hosting so it should be fine.

Can't see anything wrong with your code, I use SqlExpress and it works fine when I use a connection string in the constructor.

You have created an App_Data folder in your project, haven't you?

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

This worked for me. may help some one. Turn off firewall. on RHEL 7

systemctl stop  firewalld

• Save your work,
  
• Close Visual Studio, then
  
• Re-open your project

This worked for me.

import cx_Oracle
   dsn_tns = cx_Oracle.makedsn('host', 'port', service_name='give service name') 
   conn = cx_Oracle.connect(user='username', password='password', dsn=dsn_tns) 
   c = conn.cursor()
   c.execute('select count(*) from schema.table_name')
for row in c:
   print row
conn.close()

Note :

1. In (dsn_tns) if needed, place an 'r' before any parameter in order to address any special character such as '\'.

2. In (conn) if needed, place an 'r' before any parameter in order to address any special character such as '\'. For example, if your user name contains '\', you'll need to place 'r' before the user name: user=r'User Name' or password=r'password'

3. use triple quotes if you want to spread your query across multiple lines.

sp_who2 will actually provide a list of connections for the database server, not a database. To view connections for a single database (YourDatabaseName in this example), you can use

DECLARE @AllConnections TABLE(
    SPID INT,
    Status VARCHAR(MAX),
    LOGIN VARCHAR(MAX),
    HostName VARCHAR(MAX),
    BlkBy VARCHAR(MAX),
    DBName VARCHAR(MAX),
    Command VARCHAR(MAX),
    CPUTime INT,
    DiskIO INT,
    LastBatch VARCHAR(MAX),
    ProgramName VARCHAR(MAX),
    SPID_1 INT,
    REQUESTID INT
)

INSERT INTO @AllConnections EXEC sp_who2

SELECT * FROM @AllConnections WHERE DBName = 'YourDatabaseName'

(Adapted from SQL Server: Filter output of sp_who2.)

Use localhost instead of your IP address.

e.g,

$myServer = "localhost";

And also double check your mysql username and password.

In SQL Server 2008 in addition to the above two options you have a third option to make this setting through SQL Server Management Studio.

1.Start Management Studio and connect to Report Server Instance (make sure you select 'Reporting Services' server type).

2.Right click on the ReportServer and Select Properties

3.Click Advanced

4.In EnableRemoteErrors, select True.

5.Click OK.

Locate your postgres file it could be in /usr/local/var/postgres/ or in /usr/var/postgres/ and then delete the postmaster.pid file present in that folder.

Why this error is so boresome and noisy, just because it can occur in varied situation.

I have done all approchs above here, and still being sucked. So make sure u have done the same as me before browsing downward.

Maybe I am not able to fix ur situation instantly, but I can point out a direction or thinking to u(The one who finally slide down here). I have started to ponder the error of my running program occurring after I made sure that the instance name is clearly right and set my database to allow remote control following the methods above. After then, I suspected something wrong happening in my code snippet of SQL connection.

Solution of my problem:

• Check my sqlconnection function

• Click to see its configuration

• New a connection

• Select ur server name

It works for me with pondering what exactly happen in the process of connection.Hope my thinking will lead u to kill ur error.

This is a PDO-only visualization, as the mysql_* library is deprecated.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    $port="3306";
    // End Vault

    try {
        $dbh = new PDO("mysql:host=$host;port=$port;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        echo "I am connected.<br/>";

        // ... continue with your code

        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306 always, then consider removing it from the uri, that is, remove the port=$port; part.

If you often change ports, consider the above port usage for more maintainability having changes made to the $port variable.

Some likely errors returned from above:

PDO Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
PDO Exception: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.

In the below error, we are at least getting closer, after changing our connect information:

PDO Exception: SQLSTATE[HY000] [1045] Access denied for user 'GuySmiley'@'localhost' (using password: YES)

After further changes, we are really close now, but not quite:

PDO Exception: SQLSTATE[HY000] [1049] Unknown database 'mustard'

From the Manual on PDO Connections:

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 .

Please note that you must install the driver for the version of your software client(MS access) not the version of the OS. that's mean that if your MS Access is a 32-bits version,you must install a 32-bit odbc driver. regards

Oh, I just found that command on PostgreSQL forum:

SELECT * FROM pg_stat_activity;

"Line 1" - maybe something about windows vs unix newlines? (as i saw windows 7 mentioned above).

list(data_set.itertuples(index=False))

As of 17.1, the above will return a list of namedtuples.

If you want a list of ordinary tuples, pass name=None as an argument:

list(data_set.itertuples(index=False, name=None))

Old, but still helps...

Another great way of achieving the same behavior is through configuration file (web.config)

 <system.net>
    <settings>
      <servicePointManager checkCertificateName="false" checkCertificateRevocationList="false" />
    </settings>
  </system.net>

NOTE: tested on .net full.

I have added the following line to my /etc/mysql/my.cnf file:

default_time_zone='+00:00'

Restarted the MySQL server:

systemctl restart mysql

And it works like a charm.

You can create Session on server and share sessionId in between client and server with each REST call.

1. First authenticate REST request: /authenticate. Returns response (as per your client format) with sessionId: ABCDXXXXXXXXXXXXXX;

2. Store this sessionId in Map with actual session. Map.put(sessionid, session) or use SessionListener to create and destroy keys for you;

   public void sessionCreated(HttpSessionEvent arg0) {

You can use the @NamedEntityGraph annotation to your entity to create a loadable query that set which collections you want to load on your query.

The main advantage of this choice is that hibernate makes one single query to retrieve the entity and its collections and only when you choose to use this graph, like this:

Entity configuration

@Entity
@NamedEntityGraph(name = "graph.myEntity.addresesAndPersons", 
attributeNodes = {
    @NamedAttributeNode(value = "addreses"),
    @NamedAttributeNode(value = "persons"
})

Usage

public MyEntity findNamedGraph(Object id, String namedGraph) {
        EntityGraph<MyEntity> graph = em.getEntityGraph(namedGraph);

        Map<String, Object> properties = new HashMap<>();
        properties.put("javax.persistence.loadgraph", graph);

        return em.find(MyEntity.class, id, properties);
    }

Here is a little research that explored RDBMS vs NoSQL using MySQL vs Mongo, the conclusions were inline with @Sean Reilly's response. In short, the benefit comes from the design, not some raw speed difference. Conclusion on page 35-36:

RDBMS vs NoSQL: Performance and Scaling Comparison

The project tested, analysed and compared the performance and scalability of the two database types. The experiments done included running different numbers and types of queries, some more complex than others, in order to analyse how the databases scaled with increased load. The most important factor in this case was the query type used as MongoDB could handle more complex queries faster due mainly to its simpler schema at the sacrifice of data duplication meaning that a NoSQL database may contain large amounts of data duplicates. Although a schema directly migrated from the RDBMS could be used this would eliminate the advantage of MongoDB’s underlying data representation of subdocuments which allowed the use of less queries towards the database as tables were combined. Despite the performance gain which MongoDB had over MySQL in these complex queries, when the benchmark modelled the MySQL query similarly to the MongoDB complex query by using nested SELECTs MySQL performed best although at higher numbers of connections the two behaved similarly. The last type of query benchmarked which was the complex query containing two JOINS and and a subquery showed the advantage MongoDB has over MySQL due to its use of subdocuments. This advantage comes at the cost of data duplication which causes an increase in the database size. If such queries are typical in an application then it is important to consider NoSQL databases as alternatives while taking in account the cost in storage and memory size resulting from the larger database size.

May be i will help out some of you that even though if you are unable to open mysql from terminal after trying changing path in .bash_profile

then you always found the error "MYSQL not found" hence you can use the following command directly it will ask for your password and sql bash is opened

/usr/local/mysql/bin/mysql -u root -p

http://en.wikipedia.org/wiki/Collation

Collation is the assembly of written information into a standard order. (...) A collation algorithm such as the Unicode collation algorithm defines an order through the process of comparing two given character strings and deciding which should come before the other.

If this is a programming question, then I would suggest you write your own regular expression to parse all the retrieved contents. Target tags are IMG and A for standard HTML. For JAVA,

final String openingTags = "(<a [^>]*href=['\"]?|<img[^> ]* src=['\"]?)";

this along with Pattern and Matcher classes should detect the beginning of the tags. Add LINK tag if you also want CSS.

However, it is not as easy as you may have intially thought. Many web pages are not well-formed. Extracting all the links programmatically that human being can "recognize" is really difficult if you need to take into account all the irregular expressions.

Good luck!

I haven't tried specifically getting the VM settings, but there is a wealth of information in the JMX utilities specifically the MXBean utilities. This would be where I would start. Hopefully you find something there to help you.

The sun website has a bunch on the technology:

I rewrote David's answer using the with statement, it allows you do do this:

with timeout(seconds=3):
    time.sleep(4)

Which will raise a TimeoutError.

The code is still using signal and thus UNIX only:

import signal

class timeout:
    def __init__(self, seconds=1, error_message='Timeout'):
        self.seconds = seconds
        self.error_message = error_message
    def handle_timeout(self, signum, frame):
        raise TimeoutError(self.error_message)
    def __enter__(self):
        signal.signal(signal.SIGALRM, self.handle_timeout)
        signal.alarm(self.seconds)
    def __exit__(self, type, value, traceback):
        signal.alarm(0)

The another reason can be the following:
I changed my Url for Web Api method according to this answer:

Url.Action("MyAction", "MyApiCtrl", new { httproute = "" })

But this method creates link like:

/api/MyApiCtrl?action=MyAction

This works correctly with GET and POST requests but not with PUT or DELETE.
So I just replaced it with:

/api/MyApiCtrl

and it fixed the problem.

mysqldump --no-create-info ...

Also you may use:

• --skip-triggers: if you are using triggers
• --no-create-db: if you are using --databases ... option
• --compact: if you want to get rid of extra comments

It's the response code a SIP User Agent Server (UAS) will send to the client after the client sends a CANCEL request for the original unanswered INVITE request (yet to receive a final response).

Here is a nice CANCEL SIP Call Flow illustration.

If you're not using auto-incrementing fields, you can achieve a similar result with something like the following:

insert into Customers (ID, FirstName, LastName)
    select max(ID)+1, 'Barack', 'Obama' from Customers;

This will ensure there's no chance of a race condition which could be caused by someone else inserting into the table between your extraction of the maximum ID and your insertion of the new record.

This is using standard SQL, there are no doubt better ways to achieve it with specific DBMS' but they're not necessarily portable (something we take very seriously in our shop).

=IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3)

This will firstly check if the cell contains a space, if it does it will return the first value from the space, otherwise it will return the cell value.

Edit

Just to add to the above formula, as it stands if there is no value in the cell it would return 0. If you are looking to display a message or something to tell the user it is empty you could use the following:

=IF(IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3)=0, "Empty", IFERROR(LEFT(A3, FIND(" ", A3, 1)), A3))

In addition to @Jason's answer I had to do a bit more to get my app to run.

• Download & unzip Eclipse IDE for Java EE Developers (Note the EE edition)
• Download & unzip Eclipse's Web Tools Platform Stable (Milestone) 3.6+
• Overwrite the two folders in the Eclipse IDE, with the WTP folder(s) (features & plugins folders)
• Download and unzip Tomcat 8
• In eclipse new -> other -> server -> Tomcat 8 (choose the unzipped location)
• If you get a 404, click the Tomcat 8 in the Servers view -> Server Locations -> Change to Use Tomcat installation, and change the Deploy path: to webapps * (If you can't edit this, delete any published webapps)

You can simply use this code or copy the function below. All neatly in one line.

def substring(whole, sub1, sub2):
    return whole[whole.index(sub1) : whole.index(sub2)]

If you run the function as follows.

print(substring("5+(5*2)+2", "(", "("))

You will pobably be left with the output:

(5*2

rather than

5*2

If you want to have the sub-strings on the end of the output the code must look like below.

return whole[whole.index(sub1) : whole.index(sub2) + 1]

But if you don't want the substrings on the end the +1 must be on the first value.

return whole[whole.index(sub1) + 1 : whole.index(sub2)]

(function ($) {
    $(document).ready(function(){
    $("#myspan").text("This is span");
  });
}(jQuery));

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<span id="myspan"> hereismytext </span>

user text() to change span text.

Simply make an object and extract arguments from that object.

let checkIfNumbersAddToTen = function (a, b) {
return new Promise(function (resolve, reject) {
 let c = parseInt(a)+parseInt(b);
 let promiseResolution = {
     c:c,
     d : c+c,
     x : 'RandomString'
 };
 if(c===10){
     resolve(promiseResolution);
 }else {
     reject('Not 10');
 }
});
};

Pull arguments from promiseResolution.

checkIfNumbersAddToTen(5,5).then(function (arguments) {
console.log('c:'+arguments.c);
console.log('d:'+arguments.d);
console.log('x:'+arguments.x);
},function (failure) {
console.log(failure);
});

The easiest way is to make a "fake show" by using jquery.

element.delay(1000).fadeIn(0); // This will work

I faced the same problem and resolved it by creating a static class Parameters after adding an Application Configuration File to the project:

public static class Parameters
{
    // For a Web Application
    public static string PathConfig { get; private set; } =
        Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "web.config");

    // For a Class Library
    public static string PathConfig { get; private set; } =
        Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin", "LibraryName.dll.config");

    public static string GetParameter(string paramName)
    {
        string paramValue = string.Empty;

        using (Stream stream = File.OpenRead(PathConfig))
        {
            XDocument xdoc = XDocument.Load(stream);

            XElement element = xdoc.Element("configuration").Element("appSettings").Elements().First(a => a.Attribute("key").Value == paramName);
            paramValue = element.Attribute("value").Value;
        }

        return paramValue;
    }
}

Then get a parameter like this:

Parameters.GetParameter("keyName");

If you need to manually read a properties file without using @Value.

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

I originally found a CSS way to bypass this when using the Cycle jQuery plugin. Cycle uses JavaScript to set my slide to overflow: hidden, so when setting my pictures to width: 100% the pictures would look vertically cut, and so I forced them to be visible with !important and to avoid showing the slide animation out of the box I set overflow: hidden to the container div of the slide. Hope it works for you.

UPDATE - New Solution:

Original problem -> http://jsfiddle.net/xMddf/1/ (Even if I use overflow-y: visible it becomes "auto" and actually "scroll".)

#content {
    height: 100px;
    width: 200px;
    overflow-x: hidden;
    overflow-y: visible;
}

The new solution -> http://jsfiddle.net/xMddf/2/ (I found a workaround using a wrapper div to apply overflow-x and overflow-y to different DOM elements as James Khoury advised on the problem of combining visible and hidden to a single DOM element.)

#wrapper {
    height: 100px;
    overflow-y: visible;
}
#content {
    width: 200px;
    overflow-x: hidden;
}

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

Some x86 instructions are designed to leave the content of the operands (registers) as they are and just set/unset specific internal CPU flags like the zero-flag (ZF). You can think at the ZF as a true/false boolean flag that resides inside the CPU.

in this particular case, TEST instruction performs a bitwise logical AND, discards the actual result and sets/unsets the ZF according to the result of the logical and: if the result is zero it sets ZF = 1, otherwise it sets ZF = 0.

Conditional jump instructions like JE are designed to look at the ZF for jumping/notjumping so using TEST and JE together is equivalent to perform a conditional jump based on the value of a specific register:

example:

TEST EAX,EAX
JE some_address

the CPU will jump to "some_address" if and only if ZF = 1, in other words if and only if AND(EAX,EAX) = 0 which in turn it can occur if and only if EAX == 0

the equivalent C code is:

if(eax == 0)
{
    goto some_address
}

if you want destroy dark background of dialog , use this

dialog.getWindow().setDimAmount(0);

This will spool the output from the anonymous block into a file called output_<YYYYMMDD>.txt located in the root of the local PC C: drive where <YYYYMMDD> is the current date:

EDIT:

After your comment to output a value for every iteration of a cursor (I realise each value will be the same in this example but you should get the gist of what i'm doing):

BEGIN
   c := a+10;
   --
   FOR i IN 1 .. 10
   LOOP
      c := a+10;
      -- Output the value of C

hello here is my structure for multi process

from multiprocessing import Process
import time


start = time.perf_counter()


def do_something(time_for_sleep):
    print(f'Sleeping {time_for_sleep} second...')
    time.sleep(time_for_sleep)
    print('Done Sleeping...')



p1 = Process(target=do_something, args=[1])
p2 = Process(target=do_something, args=[2])


if 

__name__ == '__main__':
    p1.start()
    p2.start()

    p1.join()
    p2.join()

    finish = time.perf_counter()
    print(f'Finished in {round(finish-start,2 )} second(s)')

you don't have to put imports in the name == 'main', just running the program you wish to running inside

ScriptManager control can also be used to reference javascript files. One catch is that the ScriptManager control needs to be place inside the form tag. I myself prefer ScriptManager control and generally place it just above the closing form tag.

<asp:ScriptManager ID="sm" runat="server">
    <Scripts>
        <asp:ScriptReference Path="~/Scripts/yourscript.min.js" />
    </Scripts>
</asp:ScriptManager>

$(: ...) is a little less ugly, but still not good.

Other answers here address the general question of what the proper Content-Type for an XML response is, and conclude (as with What's the difference between text/xml vs application/xml for webservice response) that both text/xml and application/xml are permissible. However, none address whether there are any rules specific to sitemaps.

Answer: there aren't. The sitemap spec is https://www.sitemaps.org, and using Google site: searches you can confirm that it does not contain the words or phrases mime, mimetype, content-type, application/xml, or text/xml anywhere. In other words, it is entirely silent on the topic of what Content-Type should be used for serving sitemaps.

In the absence of any commentary in the sitemap spec directly addressing this question, we can safely assume that the same rules apply as when choosing the Content-Type of any other XML document - i.e. that it may be either text/xml or application/xml.

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;

Yes, it is normal. This is because you checkout a single commit, that doesnt have a head. Especially it is (sooner or later) not a head of any branch.

But there is usually no problem with that state. You may create a new branch from the tag, if this makes you feel safer :)

Using msdeploy.exe

Caveat: msdeploy.exe fails to create the destination database on its own, so you need to create it manually first.

1. Copy the connection string on the database properties page. Adjust it so that it contains a correct password.
2. Get the connection string for the destination DB.

3. Run msdeploy.exe like this:

   "c:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe" -verb:sync -dest:dbDacFx="destination_DB_connection_string",dropDestinationDatabase=true -source:dbDacFx="azure_DB_connection_string",includeData=true -verbose
   

Using SqlPackage.exe

1. Export the azure DB to a bacpac package.

   "c:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe" /a:Export /ssn:"azure_db_server" /sdn:"azure_db_name" /su:"user_name" /sp:"password" /tf:"file.bacpac"
   

2. Import the package to a local DB.

   "c:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin\SqlPackage.exe" /a:Import /SourceFile:"file.bacpac" /TargetServerName:".\SQLEXPRESS" /TargetDatabaseName:CopyOfAzureDb
   

What Mark Rushakoff said is true, but if you iterate in the opposite direction, it is possible to remove elements from the list in the for-loop as well. E.g.,

x = [1,2,3,0,0,1]
for i in range(len(x)-1, -1, -1):
    if x[i] == 0:
        x.pop(i)

It's like a tall building that falls from top to bottom: even if it is in the middle of collapse, you still can "enter" into it and visit yet-to-be-collapsed floors.

If you have multiple source files, you probably actually want to use link-time-optimization to output one bitcode file for the entire program. The other answers given will cause you to end up with a bitcode file for every source file.

Instead, you want to compile with link-time-optimization

clang -flto -c program1.c -o program1.o
clang -flto -c program2.c -o program2.o

and for the final linking step, add the argument -Wl,-plugin-opt=also-emit-llvm

clang -flto -Wl,-plugin-opt=also-emit-llvm program1.o program2.o -o program

This gives you both a compiled program and the bitcode corresponding to it (program.bc). You can then modify program.bc in any way you like, and recompile the modified program at any time by doing

clang program.bc -o program

although be aware that you need to include any necessary linker flags (for external libraries, etc) at this step again.

Note that you need to be using the gold linker for this to work. If you want to force clang to use a specific linker, create a symlink to that linker named "ld" in a special directory called "fakebin" somewhere on your computer, and add the option

-B/home/jeremy/fakebin

to any linking steps above.

The substitute of fcntl on windows are win32api calls. The usage is completely different. It is not some switch you can just flip.

In other words, porting a fcntl-heavy-user module to windows is not trivial. It requires you to analyze what exactly each fcntl call does and then find the equivalent win32api code, if any.

There's also the possibility that some code using fcntl has no windows equivalent, which would require you to change the module api and maybe the structure/paradigm of the program using the module you're porting.

If you provide more details about the fcntl calls people can find windows equivalents.

You just need to install Android development kit from http://developer.android.com/sdk/installing/studio.html#Updating

and also Download and install Java JDK (Choose the Java platform)

Voila ! You are Donezo !

I wanted a solution for Gnu sort on Windows, but none of the above solutions worked for me on the command line.

Using Lloyd's clue, the following batch file (.bat) worked for me.

Type the tab character within the double quotes.

C:\>cat foo.bat

sort -k3 -t"    " tabfile.txt

Here's a fun solution:

/**
 * Filter-map. Like map, but skips undefined values.
 *
 * @param callback
 */
function fmap(callback) {
    return this.reduce((accum, ...args) => {
        let x = callback(...args);
        if(x !== undefined) {
            accum.push(x);
        }
        return accum;
    }, []);
}

Use with the bind operator:

[1,2,-1,3]::fmap(x => x > 0 ? x * 2 : undefined); // [2,4,6]

You say that the date is used in connection with web services, so I assume that is serialized into a string at some point.

If this is the case, you should take a look at the setTimeZone method of the DateFormat class. This dictates which time zone that will be used when printing the time stamp.

A simple example:

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));

Calendar cal = Calendar.getInstance();
String timestamp = formatter.format(cal.getTime());

Variant that works without crashing (at least on win32; python 2.7, ipython 0.12) then called subsequently (multiple times):

def DisOutBuffering():
    if sys.stdout.name == '<stdout>':
        sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)

    if sys.stderr.name == '<stderr>':
        sys.stderr = os.fdopen(sys.stderr.fileno(), 'w', 0)

Besides its use as a placeholder for unimplemented functions, pass can be useful in filling out an if-else statement ("Explicit is better than implicit.")

def some_silly_transform(n):
    # Even numbers should be divided by 2
    if n % 2 == 0:
        n /= 2
        flag = True
    # Negative odd numbers should return their absolute value
    elif n < 0:
        n = -n
        flag = True
    # Otherwise, number should remain unchanged
    else:
        pass

Of course, in this case, one would probably use return instead of assignment, but in cases where mutation is desired, this works best.

The use of pass here is especially useful to warn future maintainers (including yourself!) not to put redundant steps outside of the conditional statements. In the example above, flag is set in the two specifically mentioned cases, but not in the else-case. Without using pass, a future programmer might move flag = True to outside the condition—thus setting flag in all cases.

Another case is with the boilerplate function often seen at the bottom of a file:

if __name__ == "__main__":
    pass

In some files, it might be nice to leave that there with pass to allow for easier editing later, and to make explicit that nothing is expected to happen when the file is run on its own.

Finally, as mentioned in other answers, it can be useful to do nothing when an exception is caught:

try:
    n[i] = 0
except IndexError:
    pass

There isn't any need to install the JDK, which is the developer kit, just the JRE which is the runtime environment.

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
              [5, 6, 7, 8],
              [9, 10, 11, 12],
              [13, 14, 15, 16]])  # added some commas and array creation code

fig = plt.figure(figsize=(6, 3.2))

ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')

cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()

You can add HTML into an alert string, but it will not render as HTML. It will just be displayed as a plain string. Simple answer: no.

Or maybe even easier

grep -R put **/*bills*

The ** glob syntax means "any depth of directories". It will work in Zsh, and I think recent versions of Bash too.

This is an old question but since this is the first result in google for this error, I thought I would update my progress in this issue.

I spent way too may hours on this issue. In the end I had to change my Office 365 account's password few times until my code succeeded in sending emails.

Didn't have to make any changes in code.

The average corporate programmer, e.g. most of the people I work with, will not understand it and most work environments will not let you program in it

That one is just a matter of time though. Your average corporate programmer learns whatever the current Big Thing is. 15 years ago, they didn't understand OOP. IF FP catches on, your "average corporate programmers" will follow.

It's not really taught at universities (or is it nowadays?)

Varies a lot. At my university, SML is the very first language students are introduced to. I believe MIT teaches LISP as a first-year course. These two examples may not be representative, of course, but I believe most universities at the very least offer some optional courses on FP, even if they don't make it a mandatory part of the curriculum.

Most applications are simple enough to be solved in normal OO ways

It's not really a matter of "simple enough" though. Would a solution be simpler (or more readable, robust, elegant, performant) in FP? Many things are "simple enough to be solved in Java", but it still requires a godawful amount of code.

In any case, keep in mind that FP proponents have claimed that it was the Next Big Thing for several decades now. Perhaps they're right, but keep in mind that they weren't when they made the same claim 5, 10 or 15 years ago.

One thing that definitely counts in their favor, though, is that recently, C# has taken a sharp turn towards FP, to the extent that it's practically turning a generation of programmers into FP programmers, without them even noticing. That might just pave the way for the FP "revolution". Maybe. ;)

xcopy "%userprofile%\Desktop\?????????" "D:\Backup\" /s/h/e/k/f/c

should work, assuming that your language setting allows Cyrillic (or you use Unicode fonts in the console).

For reference about the arguments: http://ss64.com/nt/xcopy.html

The problem is that your anonymous object property data-icon has an invalid name. C# properties cannot have dashes in their names. There are two ways you can get around that:

Use an underscore instead of dash (MVC will automatically replace the underscore with a dash in the emitted HTML):

@Html.ActionLink("Edit", "edit", "markets",
      new { id = 1 },
      new {@class="ui-btn-right", data_icon="gear"})

Use the overload that takes in a dictionary:

@Html.ActionLink("Edit", "edit", "markets",
      new { id = 1 },
      new Dictionary<string, object> { { "class", "ui-btn-right" }, { "data-icon", "gear" } });

Yes, in one single division you can use both but it's not very common. While styling you will call both so it will cause some ambiguity if you don't properly choose "x" and "y". Use # for ID and . for class. And for overall division you will either do separate styling or write: #x .y for styling purposes.

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

for(var key in object) {
   console.log(object[key]);
}

Try

df.loc[df.my_channel > 20000, 'my_channel'] = 0

Note: Since v0.20.0, ix has been deprecated in favour of loc / iloc.

As found on the mailing list archive,

• http://osdir.com/ml/gnu.make.windows/2004-03/msg00063.html
• http://osdir.com/ml/gnu.make.general/2005-10/msg00064.html

one can use the filter function.

For example

ifeq ($(GCC_MINOR),$(filter $(GCC_MINOR),4 5))

filter X, A B will return those of A,B that are equal to X. Note, while this is not relevant in the above example, this is a XOR operation. I.e. if you instead have something like:

ifeq (4, $(filter 4, $(VAR1) $(VAR2)))

And then do e.g. make VAR1=4 VAR2=4, the filter will return 4 4, which is not equal to 4.

A variation that performs an OR operation instead is:

ifneq (,$(filter $(GCC_MINOR),4 5))

where a negative comparison against an empty string is used instead (filter will return en empty string if GCC_MINOR doesn't match the arguments). Using the VAR1/VAR2 example it would look like this:

ifneq (, $(filter 4, $(VAR1) $(VAR2)))

The downside to those methods is that you have to be sure that these arguments will always be single words. For example, if VAR1 is 4 foo, the filter result is still 4, and the ifneq expression is still true. If VAR1 is 4 5, the filter result is 4 5 and the ifneq expression is true.

One easy alternative is to just put the same operation in both the ifeq and else ifeq branch, e.g. like this:

ifeq ($(GCC_MINOR),4)
    @echo Supported version
else ifeq ($(GCC_MINOR),5)
    @echo Supported version
else
    @echo Unsupported version
endif

Cannot be done. MsgBox buttons can only have specific values.

Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.

Kiss Jquery UI goodbye and a lightbox hello. You can get it here.

Example: index = False

import pandas as pd

writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save() 

If anyone else still lands here. With ES6 you can create your html variable like so:

render(){
    var thisIsMyCopy = (
        <p>copy copy copy <strong>strong copy</strong></p>
    );
    return(
        <div>
            {thisIsMyCopy}
        </div>
    )
}

I'll tell you how it can be done in eclipse. My dev system - Windows 64bit, Eclipse Luna, Perlipse plugin for eclipse, Strawberry pearl installer. I use perl.exe as my interpreter.

Eclipse > create new perl project > right click project > build path > configure build path > libraries tab > add external source folder > go to the folder where all your perl modules are installed > ok > ok. Done !

It's a bit worse, I use a calling card for international calls, so its local number in the US + account# (6 digits) + pin (4 digits) + "pause" + what you described above.

I suspect there might be other cases

A more elegant and simple solution is to use

git stash

It will return to the most resent local version of the branch and also save your changes in stash, so if you like to undo this action do:

git stash apply

One thing you need to consider is the interaction of checkbox and radio inputs with javascript.

Using below structure:

<label>
  <input onclick="controlCheckbox()" type="checkbox" checked="checkboxState" />
  <span>Label text</span>
</label>

When user clicks on "Label text" controlCheckbox() function will be fired once.

But when input tag is clicked the controlCheckbox() function may be fired twice in some older browsers. That's because both input and label tags trigger onclick event attached to checkbox.

Then you may have some bugs in your checkboxState.

I've run into this issue lately on IE11. I'm not sure if modern browsers have troubles with this structure.

One liner using pathlib:

list_subfolders_with_paths = [p for p in pathlib.Path(path).iterdir() if p.is_dir()]

Here is what I do, which is basically straight from the example(Startup) page:

## Default repo
local({r <- getOption("repos")
       r["CRAN"] <- "http://cran.r-project.org" 
       options(repos=r)
})

which is in ~/.Rprofile.

Edit: As it is now 2018, we can add that for the last few years the URL "https://cloud.r-project.org" has been preferable as it reflects a) https access and b) an "always-near-you" CDN.

UPDATE

While these methods work, newer versions of VS Code uses the Ctrl+] shortcut to indent a block of code once, and Ctrl+[ to remove indentation.

This method detects the indentation in a file and indents accordingly.You can change the size of indentation by clicking on the Select Indentation setting in the bottom right of VS Code (looks something like "Spaces: 2"), selecting "Indent using Spaces" from the drop-down menu and then selecting by how many spaces you would like to indent.

edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).

As simple as:

JSON.stringify(yourData)

You should encode you data in JSON before sending it, you can't just send an object like this as POST data.

I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:

$.post(_saveDeviceUrl, {
    data : $.toJSON(postData)
}, function(response){
    //Process your response here
}
);

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

I made a super simple class to handle this in a Mac application I'm working on. Hopefully, this is helpful to someone

RadioButtonController Class:

class RadioButtonController: NSObject {

var buttonArray : [NSButton] = []
var currentleySelectedButton : NSButton?
var defaultButton : NSButton = NSButton() {
    didSet {
        buttonArrayUpdated(buttonSelected: self.defaultButton)
    }
}

func buttonArrayUpdated(buttonSelected : NSButton) {
    for button in buttonArray {
        if button == buttonSelected {
            currentleySelectedButton = button
            button.state = .on
        } else {
            button.state = .off
        }
    }
}

}

Implementation in View Controller:

class OnboardingDefaultLaunchConfiguration: NSViewController {

let radioButtonController : RadioButtonController = RadioButtonController()
@IBOutlet weak var firstRadioButton: NSButton!
@IBOutlet weak var secondRadioButton: NSButton!

@IBAction func folderRadioButtonSelected(_ sender: Any) {
    radioButtonController.buttonArrayUpdated(buttonSelected: folderGroupRadioButton)
}

@IBAction func fileListRadioButtonSelected(_ sender: Any) {
    radioButtonController.buttonArrayUpdated(buttonSelected: fileListRadioButton)
}

override func viewDidLoad() {
    super.viewDidLoad()
    radioButtonController.buttonArray = [firstRadioButton, secondRadioButton]
    radioButtonController.defaultButton = firstRadioButton
}

}

Another way of doing this: new_df = A_df.merge(B_df, left_on=['A_c1','c2'], right_on = ['B_c1','c2'], how='left')

If that version you need to obtain is either a branch or a tag then:

git clone -b branch_or_tag_name repo_address_or_path

You can get only visible View from ListView because row views in ListView are reuseable. If you use mListView.getChildAt(0) you get first visible view. This view is associated with item from adapter at position mListView.getFirstVisiblePosition().

mySelect.value = myValue;

Where mySelect is your selection box, and myValue is the value you want to change it to.

Another easy way is to use:

mysqladmin debug 

This dumps a lot of information (including locks) to the error log.

Using aggregate function like below :

[
{$group: {_id : {book : '$book',address:'$addr'}, total:{$sum :1}}},
{$project : {book : '$_id.book', address : '$_id.address', total : '$total', _id : 0}}
]

it will give you result like following :

        {
            "total" : 1,
            "book" : "book33",
            "address" : "address90"
        }, 
        {
            "total" : 1,
            "book" : "book5",
            "address" : "address1"
        }, 
        {
            "total" : 1,
            "book" : "book99",
            "address" : "address9"
        }, 
        {
            "total" : 1,
            "book" : "book1",
            "address" : "address5"
        }, 
        {
            "total" : 1,
            "book" : "book5",
            "address" : "address2"
        }, 
        {
            "total" : 1,
            "book" : "book3",
            "address" : "address4"
        }, 
        {
            "total" : 1,
            "book" : "book11",
            "address" : "address77"
        }, 
        {
            "total" : 1,
            "book" : "book9",
            "address" : "address3"
        }, 
        {
            "total" : 1,
            "book" : "book1",
            "address" : "address15"
        }, 
        {
            "total" : 2,
            "book" : "book1",
            "address" : "address2"
        }, 
        {
            "total" : 3,
            "book" : "book1",
            "address" : "address1"
        }

I didn't quite get your expected result format, so feel free to modify this to one you need.

The way to do this is via the bracket notation.

var test = {_x000D_
    "id": "109",_x000D_
    "No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);

I know this is old, but this hung me up for awhile. The properties of the object in your list must be actual "properties", not just public members.

public class FileName
{        
     public string ThisFieldWorks {get;set;}
     public string ThisFieldDoesNot;
}

If you are using auto-generated Mongo Object Ids in your document, it contains timestamp in it as first 4 bytes using which latest doc inserted into the collection could be found out. I understand this is an old question, but if someone is still ending up here looking for one more alternative.

db.collectionName.aggregate(
[{$group: {_id: null, latestDocId: { $max: "$_id"}}}, {$project: {_id: 0, latestDocId: 1}}])

Above query would give the _id for the latest doc inserted into the collection

d = {'A': 4,'B':10}

min_v = min(zip(d.values(), d.keys()))
# min_v is (4,'A')

max_v = max(zip(d.values(), d.keys()))
# max_v is (10,'B')

The String you return here:

 return "login";

Is actually the whole content what you send back to the browser.

If you want to have the content of a file to be sent back, one way is:

1. Open file
2. Read contents into String
3. Return the value

I would strongly recommend using a library like PHPMailer to send emails.
It's easier and handles most of the issues automatically for you.

Regarding displaying embedded (inline) images, here's what's on their documentation:

Inline Attachments

There is an additional way to add an attachment. If you want to make a HTML e-mail with images incorporated into the desk, it's necessary to attach the image and then link the tag to it. For example, if you add an image as inline attachment with the CID my-photo, you would access it within the HTML e-mail with <img src="cid:my-photo" alt="my-photo" />.

In detail, here is the function to add an inline attachment:

$mail->AddEmbeddedImage(filename, cid, name);
//By using this function with this example's value above, results in this code:
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');

To give you a more complete example of how it would work:

<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on     errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

try {
  $mail->Host       = "mail.yourdomain.com"; // SMTP server
  $mail->Port       = 25;                    // set the SMTP port
  $mail->SetFrom('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->Subject = 'PHPMailer Test';

  $mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
  $mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';

  $mail->AddAttachment('something.zip'); // this is a regular attachment (Not inline)
  $mail->Send();
  echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
?>

Edit:

Regarding your comment, you asked how to send HTML email with embedded images, so I gave you an example of how to do that.
The library I told you about can send emails using a lot of methods other than SMTP.
Take a look at the PHPMailer Example page for other examples.

One way or the other, if you don't want to send the email in the ways supported by the library, you can (should) still use the library to build the message, then you send it the way you want.

For example:

You can replace the line that send the email:

$mail->Send();

With this:

$mime_message = $mail->CreateBody(); //Retrieve the message content
echo $mime_message; // Echo it to the screen or send it using whatever method you want

Hope that helps. Let me know if you run into trouble using it.

To handle the lazy loading with image existence check I followed this in jQuery-

$('[data-src]').each(function() {
  var $image_place_holder_element = $(this);
  var image_url = $(this).data('src');
  $("<div class='hidden-classe' />").load(image_url, function(response, status, xhr) {
    if (!(status == "error")) {
      $image_place_holder_element.removeClass('image-placeholder');
      $image_place_holder_element.attr('src', image_url);
    }
  }).remove();
});

Reason: if I am using $image_place_holder_element.load() method it will be adding the response to the element, so random div and removing it appeared me a good solution. Hope it works for someone trying to implement lazy loading along with url check.

I don't think there's a standard as to the location of the sitemap. That's the reason why you should specify an arbitrary URL to your sitemap when you're adding one using Google's Webmaster Tools.

Now the following wont help you with files that are already cached, but moving forward, you can use the following to easily force a request to get something new, without changing the actual filename.

# Rewrite all requests for JS and CSS files to files of the same name, without
# any numbers in them. This lets the JS and CSS be force out of cache easily
# by putting a number at the end of the filename
# e.g. a request for static/js/site-52.js will get the file static/js/site.js instead.
<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteRule ^static/(js|css)/([a-z]+)-([0-9]+)\.(js|css)$ /site/$1/$2.$4 [R=302,NC,L]
</IfModule>

Of course, the higher up in your folder structure you do this type of approach, the more you kick things out of cache with a simple change.

So for example, if you store the entire css and javascript of your site in one main folder

/assets/js
/assets/css
/assets/...

Then you can could start referencing it as "assets-XXX" in your html, and use a rule like so to kick all assets content out of cache.

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteRule ^assets-([a-z0-9]+)/(.*) /$2 [R=302,NC,L]
</IfModule> 

Note that if you do go with this, after you have it working, change the 302 to a 301, and then caching will kick in. When it's a 302 it wont cache at the browser level because it's a temporary redirect. If you do it this way, then you could bump up the expiry default time to 30 days for all assets, since you can easily kick things out of cache by simply changing the folder name in the login page.

<IfModule mod_expires.c>
  ExpiresActive on
  ExpiresDefault A2592000
</IfModule>

The simplest solution:

<artifactId>Example</artifactId>

I use requests package whenever I want something related to HTTP requests because its API is very easy to start with:

first, install requests

$ pip install requests

then the code:

from requests import get  # to make GET request


def download(url, file_name):
    # open in binary mode
    with open(file_name, "wb") as file:
        # get request
        response = get(url)
        # write to file
        file.write(response.content)

Views are not currently supported by Entity Framework Core. See https://github.com/aspnet/EntityFramework/issues/827.

That said, you can trick EF into using a view by mapping your entity to the view as if it were a table. This approach comes with limitations. e.g. you can't use migrations, you need to manually specific a key for EF to use, and some queries may not work correctly. To get around this last part, you can write SQL queries by hand

context.Images.FromSql("SELECT * FROM dbo.ImageView")

this works well without any special function needed. Much easier to write with php as well. <input onclick="this.form.submit()"/>

In case of this similar error Warning: Error in $: object of type 'closure' is not subsettable [No stack trace available]

Just add corresponding package name using :: e.g.

instead of tags(....)

write shiny::tags(....)

import random

a=[]
n=int(input("Enter number of elements:"))

for j in range(n):
       a.append(random.randint(1,20))

print('Randomised list is: ',a)

In the first regex, each space character is being replaced, character by character, with the empty string.

In the second regex, each contiguous string of space characters is being replaced with the empty string because of the +.

However, just like how 0 multiplied by anything else is 0, it seems as if both methods strip spaces in exactly the same way.

If you change the replacement string to '#', the difference becomes much clearer:

var str = '  A B  C   D EF ';
console.log(str.replace(/\s/g, '#'));  // ##A#B##C###D#EF#
console.log(str.replace(/\s+/g, '#')); // #A#B#C#D#EF#

This work perfectly for me:

To call a PHP function (with parameters too) you can, like a lot of people said, send a parameter opening the PHP file and from there check the value of the parameter to call the function. But you can also do that lot of people say it's impossible: directly call the proper PHP function, without adding code to the PHP file.

I found a way:

This for JavaScript:

function callPHP(expression, objs, afterHandler) {
        expression = expression.trim();
        var si = expression.indexOf("(");
        if (si == -1)
            expression += "()";
        else if (Object.keys(objs).length > 0) {
            var sfrom = expression.substring(si + 1);
            var se = sfrom.indexOf(")");
            var result = sfrom.substring(0, se).trim();
            if (result.length > 0) {
                var params = result.split(",");
                var theend = expression.substring(expression.length - sfrom.length + se);
                expression = expression.substring(0, si + 1);
                for (var i = 0; i < params.length; i++) {
                    var param = params[i].trim();
                    if (param in objs) {
                        var value = objs[param];
                        if (typeof value == "string")
                            value = "'" + value + "'";
                        if (typeof value != "undefined")
                            expression += value + ",";
                    }
                }
                expression = expression.substring(0, expression.length - 1) + theend;
            }
        }
        var doc = document.location;
        var phpFile = "URL of your PHP file";
        var php =
            "$docl = str_replace('/', '\\\\', '" + doc + "'); $absUrl = str_replace($docl, $_SERVER['DOCUMENT_ROOT'], str_replace('/', '\\\\', '" + phpFile + "'));" +
            "$fileName = basename($absUrl);$folder = substr($absUrl, 0, strlen($absUrl) - strlen($fileName));" +
            "set_include_path($folder);include $fileName;" + expression + ";";
        var url = doc + "/phpCompiler.php" + "?code=" + encodeURIComponent(php);
        $.ajax({
            type: 'GET',
            url: url,
            complete: function(resp){
                var response = resp.responseText;
                afterHandler(response);
            }
        });
    }

This for a PHP file which isn't your PHP file, but another, which path is written in url variable of JS function callPHP , and it's required to evaluate PHP code. This file is called 'phpCompiler.php' and it's in the root directory of your website:

<?php
$code = urldecode($_REQUEST['code']);
$lines = explode(";", $code);
foreach($lines as $line)
    eval(trim($line, " ") . ";");
?>

So, your PHP code remain equals except return values, which will be echoed:

<?php
function add($a,$b){
  $c=$a+$b;
  echo $c;
}
function mult($a,$b){
  $c=$a*$b;
  echo $c;
}

function divide($a,$b){
  $c=$a/$b;
  echo $c;
}
?>

I suggest you to remember that jQuery is required:
Download it from Google CDN:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

or from Microsoft CDN: "I prefer Google! :)"

<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js"></script>

Better is to download the file from one of two CDNs and put it as local file, so the startup loading of your website's faster!

The choice is to you!

//Names of parameters are custom, they haven't to be equals of these of the PHP file.
//These fake names are required to assign value to the parameters in PHP
//using an hash table.
callPHP("add(num1, num2)", {
            'num1' : 1,
            'num2' : 2
        },
            function(output) {
                alert(output); //This to display the output of the PHP file.
        });

We use something like this [use in one line]:

<a title="send to Facebook" 
  href="http://www.facebook.com/sharer.php?s=100&p[title]=YOUR_TITLE&p[summary]=YOUR_SUMMARY&p[url]=YOUR_URL&p[images][0]=YOUR_IMAGE_TO_SHARE_OBJECT"
  target="_blank">
  <span>
    <img width="14" height="14" src="'icons/fb.gif" alt="Facebook" /> Facebook 
  </span>
</a>

Here is a batch file that generates all 10.x.x.x addresses

@echo off

SET /A X=0
SET /A Y=0
SET /A Z=0

:loop
SET /A X+=1
echo 10.%X%.%Y%.%Z%
IF "%X%" == "256" (
 GOTO end
 ) ELSE (
 GOTO loop2
 GOTO loop
 )


:loop2
SET /A Y+=1
echo 10.%X%.%Y%.%Z%
IF "%Y%" == "256" (
  SET /A Y=0
  GOTO loop
  ) ELSE (
   GOTO loop3
   GOTO loop2
 )


:loop3

SET /A Z+=1
echo 10.%X%.%Y%.%Z%
IF "%Z%" == "255" (
  SET /A Z=0
  GOTO loop2
 ) ELSE (
   GOTO loop3
 )

:end

If you're trying to hide upload img and show bandwidth img on bandwidth click and viceversa this would work

<script>

    function show_img(id)
    {
        if(id=='bandwidth')
        {
           $("#upload").hide();
           $("#bandwith").show();
        }
        else if(id=='upload')
        {
            $("#upload").show();
            $("#bandwith").hide();
        }
    return false;
     } 
    </script>
    <a href="#" onclick="javascript:show_img('bandwidth');">Bandwidth</a>
    <a href="#" onclick="javascript:show_img('upload');">Upload</a>
    <p align="center"> 
      <img src="/media/img/close.png" style="visibility: hidden;" id="bandwidth"/>
      <img src="/media/img/close.png" style="visibility: hidden;" id="upload"/>
    </p>

here is the easiest way to add progress bar in android Web View.

Add a boolean field in your activity/fragment

private boolean isRedirected;

This boolean will prevent redirection of web pages cause of dead links.Now you can just pass your WebView object and web Url into this method.

private void startWebView(WebView webView,String url) {

    webView.setWebViewClient(new WebViewClient() {
        ProgressDialog progressDialog;

        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            isRedirected = true;
            return false;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            isRedirected = false;
        }

        public void onLoadResource (WebView view, String url) {
            if (!isRedirected) {
                if (progressDialog == null) {
                    progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                    progressDialog.setMessage("Loading...");
                    progressDialog.show();
                }
            }

        }
        public void onPageFinished(WebView view, String url) {
            try{
                isRedirected=true;

                if (progressDialog.isShowing()) {
                    progressDialog.dismiss();
                    progressDialog = null;
                }



            }catch(Exception exception){
                exception.printStackTrace();
            }
        }

    });

    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(url);
}

Here when start loading it will call onPageStarted. Here i setting Boolean field is false. But when page load finish it will come to onPageFinished method and here Boolean field is set to true. Sometimes if url is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason it will not hiding the progress bar. To prevent this i am checking if (!isRedirected) in onLoadResource()

in onPageFinished() method before dismissing the Progress Dialog you can write your 10 second time delay code

That's it. Happy coding :)

Put this at the top of your .py file (for python 2.x)

#!/usr/bin/env python 

or for python 3.x

#!/usr/bin/env python3

This should look up the python environment, without it, it will execute the code as if it were not python code, but straight to the CLI. If you need to specify a manual location of python environment put

#!/#path/#to/#python

When using any form of Ajax, detailed documentation for the format of responses received from the CGI server seems to be lacking on the Web. Some entries here point out that newlines in returned text or json data must be escaped to prevent infinite loops (hangs) in JSON conversion (possibly created by throwing an uncaught exception), whether done automatically by jQuery or manually using Javascript system or library JSON parsing calls.

In each case where programmers post this problem, inadequate solutions are presented (most often replacing \n by \\n on the sending side) and the matter is dropped. Their inadequacy is revealed when passing string values that accidentally embed control escape sequences, such as Windows pathnames. An example is "C:\Chris\Roberts.php", which contains the control characters ^c and ^r, which can cause JSON conversion of the string {"file":"C:\Chris\Roberts.php"} to loop forever. One way of generating such values is deliberately to attempt to pass PHP warning and error messages from server to client, a reasonable idea.

By definition, Ajax uses HTTP connections behind the scenes. Such connections pass data using GET and POST, both of which require encoding sent data to avoid incorrect syntax, including control characters.

This gives enough of a hint to construct what seems to be a solution (it needs more testing): to use rawurlencode on the PHP (sending) side to encode the data, and unescape on the Javascript (receiving) side to decode the data. In some cases, you will apply these to entire text strings, in other cases you will apply them only to values inside JSON.

If this idea turns out to be correct, simple examples can be constructed to help programmers at all levels solve this problem once and for all.

As per the other answers, set the output logging level to detailed and search there for conflicts, that will tell you where to look next.

In my case, it sent me off in a few directions looking for the source of the references, but in the end it turned out that the problem was one of my portable class library projects, it was targeting the wrong version and was pulling its own version of the references in, hence the conflicts. A quick re-target and the problem was solved.

For multiple elements, you should give it a class rather than id eg:

<input type="text" class="task" name="task[]" />

Now you can get those using jquery something like this:

$('.task').each(function(){
   alert($(this).val());
});

It's simple, you're just not in the right directory.

Go to the C:\Program Files\nodejs\node_modules\npm and you should be able to run this command properly.

As @markus said use the "Cookie Manager" and delete the cookie.

If you want to learn how to set destroy cookies in postman, You should check the Postman Echo service https://docs.postman-echo.com/

There you will find complete explanation on how to Set, Get and Delete those cookies.

Check it on : https://docs.postman-echo.com/#3de3b135-b3cc-3a68-ba27-b6d373e03c8c

Give it a Try.

Generally you can define the precision of a number in SQL by defining it with parameters. For most cases this will be NUMERIC(10,2) or Decimal(10,2) - will define a column as a Number with 10 total digits with a precision of 2 (decimal places).

Edited for clarity

in the header:

enum EFooOptions
 {
FooOptionsA = 0, EFooOptionsMin = 0,
FooOptionsB,
FooOptionsC,
FooOptionsD 
EFooOptionsMax
};
extern const wchar* FOO_OPTIONS[EFooOptionsMax];

in the .cpp file:

const wchar* FOO_OPTIONS[] = {
    L"One",
    L"Two",
    L"Three",
    L"Four"
};

Caveat: Don't handle bad array index. :) But you can easily add a function to verify the enum before getting the string from the array.

I was parsing JSON from a REST API call and got this error. It turns out the API had become "fussier" (eg about order of parameters etc) and so was returning malformed results. Check that you are getting what you expect :)

PEP 8 advises the first form for readability. You can find it here.

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

We use the logging module for this.

For example:

import logging
class SomeTest( unittest.TestCase ):
    def testSomething( self ):
        log= logging.getLogger( "SomeTest.testSomething" )
        log.debug( "this= %r", self.this )
        log.debug( "that= %r", self.that )
        # etc.
        self.assertEquals( 3.14, pi )

if __name__ == "__main__":
    logging.basicConfig( stream=sys.stderr )
    logging.getLogger( "SomeTest.testSomething" ).setLevel( logging.DEBUG )
    unittest.main()

That allows us to turn on debugging for specific tests which we know are failing and for which we want additional debugging information.

My preferred method, however, isn't to spend a lot of time on debugging, but spend it writing more fine-grained tests to expose the problem.

append a text node as follows

var td1 = document.getElementById('td1');
var text = document.createTextNode("some text");
td1.appendChild(text);

void intSwap (int *pa, int *pb){
    int temp = *pa;
    *pa = *pb;
    *pb = temp;
}

You need to know the following -

int a = 5; // an integer, contains value
int *p; // an integer pointer, contains address
p = &a; // &a means address of a
a = *p; // *p means value stored in that address, here 5

void charSwap(char* a, char* b){
    char temp = *a;
    *a = *b;
    *b = temp;
}

So, when you swap like this. Only the value will be swapped. So, for a char* only their first char will swap.

Now, if you understand char* (string) clearly, then you should know that, you only need to exchange the pointer. It'll be easier to understand if you think it as an array instead of string.

void stringSwap(char** a, char** b){
    char *temp = *a;
    *a = *b;
    *b = temp;
}

So, here you are passing double pointer because starting of an array itself is a pointer.

This is the SortedList implementation I am using. Maybe this helps with your problem:

This solution is very flexible and uses existing Java functions:

• Completely based on generics
• Uses java.util.Collections for finding and inserting list elements
• Option to use a custom Comparator for list sorting

Some notes:

• This sorted list is not synchronized since it inherits from java.util.ArrayList. Use Collections.synchronizedList if you need this (refer to the Java documentation for java.util.ArrayList for details).
• The initial solution was based on java.util.LinkedList. For better performance, specifically for finding the insertion point (Logan's comment) and quicker get operations (https://dzone.com/articles/arraylist-vs-linkedlist-vs), this has been changed to java.util.ArrayList.

Strangely you must put the 'font-weight: 900' in some icons so that it shows them.

#mainNav .navbar-collapse .navbar-sidenav .nav-link-collapse:after {
  content: '\f107';
  font-family: 'Font Awesome\ 5 Free'; 
  font-weight: 900; /* Fix version 5.0.9 */
}

I prefer fmt.Printf("%+q", arr) which will print

["some" "values" "list"]

You need to CAST the ParentId as an nvarchar, so that the output is always the same data type.

SELECT Id   'PatientId',
       ISNULL(CAST(ParentId as nvarchar(100)),'')  'ParentId'
FROM Patients

I want to mention one important note regarding req.query , because currently I am working on pagination functionality based on req.query and I have one interesting example to demonstrate to you...

Example:

// Fetching patients from the database
exports.getPatients = (req, res, next) => {

const pageSize = +req.query.pageSize;
const currentPage = +req.query.currentPage;

const patientQuery = Patient.find();
let fetchedPatients;

// If pageSize and currentPage are not undefined (if they are both set and contain valid values)
if(pageSize && currentPage) {
    /**
     * Construct two different queries 
     * - Fetch all patients 
     * - Adjusted one to only fetch a selected slice of patients for a given page

         * 
         * Another example: if I am displaying 7 patients per page , I want to skip 7 items because I am on page 2,
         * so I want to skip (7 * (2 - 1)) => 7 items
         */
        .skip(pageSize * (currentPage - 1))

         * For example: If I got 7 items per page, then I want to limit the query to only
         * return 7 items. 
         */
        .limit(pageSize);
}
patientQuery.then(documents => {
    res.status(200).json({
        message: 'Patients fetched successfully',
        patients: documents
    });
  });
};

You will noticed + sign in front of req.query.pageSize and req.query.currentPage

Why? If you delete + in this case, you will get an error, and that error will be thrown because we will use invalid type (with error message 'limit' field must be numeric).

Important: By default if you extracting something from these query parameters, it will always be a string, because it's coming the URL and it's treated as a text.

If we need to work with numbers, and convert query statements from text to number, we can simply add a plus sign in front of statement.

dt.Columns[0].DataType.Name.ToString()

As @cs95 mentioned in a comment, to drop only one level, use:

df.reset_index(level=[...])

This avoids having to redefine your desired index after reset.

Use the break keyword.

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

This is wrong. It will just kill the session when the associated client (webbrowser) has not accessed the website for more than 15 minutes. The activity certainly counts, exactly as you initially expected, seeing your attempt to solve this.

The HttpSession#setMaxInactiveInterval() doesn't change much here by the way. It does exactly the same as <session-timeout> in web.xml, with the only difference that you can change/set it programmatically during runtime. The change by the way only affects the current session instance, not globally (else it would have been a static method).

To play around and experience this yourself, try to set <session-timeout> to 1 minute and create a HttpSessionListener like follows:

@WebListener
public class HttpSessionChecker implements HttpSessionListener {

    public void sessionCreated(HttpSessionEvent event) {
        System.out.printf("Session ID %s created at %s%n", event.getSession().getId(), new Date());
    }

    public void sessionDestroyed(HttpSessionEvent event) {
        System.out.printf("Session ID %s destroyed at %s%n", event.getSession().getId(), new Date());
    }

}

(if you're not on Servlet 3.0 yet and thus can't use @WebListener, then register in web.xml as follows):

<listener>
    <listener-class>com.example.HttpSessionChecker</listener-class>
</listener>

Note that the servletcontainer won't immediately destroy sessions after exactly the timeout value. It's a background job which runs at certain intervals (e.g. 5~15 minutes depending on load and the servletcontainer make/type). So don't be surprised when you don't see destroyed line in the console immediately after exactly one minute of inactivity. However, when you fire a HTTP request on a timed-out-but-not-destroyed-yet session, it will be destroyed immediately.

Split the text into lines, and draw each separately:

function fillTextMultiLine(ctx, text, x, y) {
  var lineHeight = ctx.measureText("M").width * 1.2;
  var lines = text.split("\n");
  for (var i = 0; i < lines.length; ++i) {
    ctx.fillText(lines[i], x, y);
    y += lineHeight;
  }
}

After struggling a bit with some of the answers here, I found a library called backoff that worked better for my situation. A basic example:

import backoff

@backoff.on_exception(
    backoff.expo,
    requests.exceptions.RequestException,
    max_tries=5,
    giveup=lambda e: e.response is not None and e.response.status_code < 500
)
def publish(self, data):
    r = requests.post(url, timeout=10, json=data)
    r.raise_for_status()

I'd still recommend giving the library's native functionality a shot, but if you run into any problems or need broader control, backoff is an option.

Perhaps use tikz.

If you want to show just numbers without characters, put this line of code inside your XML file android:inputType="number". The output:

If you want to show a number keyboard that also shows characters, put android:inputType="phone" on your XML. The output (with characters):

And if you want to show a number keyboard that masks your input just like a password, put android:inputType="numberpassword". The output:

I'm really sorry if I only post the links of the screenshot, I want to do research on how to do really post images here but it might consume my time so here it is. I hope my post can help other people. Yes, my answer is duplicate with other answers posted here but to save other people's time that they might need to run their code before seeing the output, my post might save you some time.

The best solution is to just do webView.loadUrl( "javascript:window.location.reload( true )" );. This should work on all versions and doesn't introduce new history entries.

I know this question is old, but the way I found the executable file for a similar application was to first open the application, then open Windows Task Manager, and in the "Processes" list right-click on it and choose "Open File Location".

I couldn't seem to find the location in the application reference file in my case...

for any extra column if there is no mapping then map it to null like the following SQL query

Select Col1, Col2, Col3, Col4, Col5 from Table1
Union
Select Col1, Col2, Col3, Null as Col4, Null as Col5 from Table2````

EDIT: You cannot overload operators in current, common browser-based implementations of JavaScript interpreters.

To answer the original question, one way you could do this, and mind you, this is a bit of a hack, simply serialize the two arrays to JSON and then compare the two JSON strings. That would simply tell you if the arrays are different, obviously you could do this to each of the objects within the arrays as well to see which ones were different.

Another option is to use a library which has some nice facilities for comparing objects - I use and recommend MochiKit.

EDIT: The answer kamens gave deserves consideration as well, since a single function to compare two given objects would be much smaller than any library to do what I suggest (although my suggestion would certainly work well enough).

Here is a naïve implemenation that may do just enough for you - be aware that there are potential problems with this implementation:

function objectsAreSame(x, y) {
   var objectsAreSame = true;
   for(var propertyName in x) {
      if(x[propertyName] !== y[propertyName]) {
         objectsAreSame = false;
         break;
      }
   }
   return objectsAreSame;
}

The assumption is that both objects have the same exact list of properties.

Oh, and it is probably obvious that, for better or worse, I belong to the only-one-return-point camp. :)

DateTime start1 = DateTime.Parse(txtDate.Text);

SELECT * 
FROM dbo.March2010 A
WHERE A.Date >= start1;

First convert TexBox into the Datetime then....use that variable into the Query

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

in mysql to get columns details and table structure by following keywords or queries

1.DESC table_name

2.DESCRIBE table_name

3.SHOW COLUMNS FROM table_name

4.SHOW create table table_name;

5.EXPLAIN table_name

I believe that you want to run in psql:

\i C:/database/db-backup.sql

A portion of Coffee here:

# My little helper
read_buffer = (buffer, callback) ->
  data = ''
  buffer.on 'readable', -> data += buffer.read().toString()
  buffer.on 'end', -> callback data

# So request looks like
http.get 'http://i.want.some/stuff', (res) ->
  read_buffer res, (response) ->
    # Do some things with your response
    # but don't do that exactly :D
    eval(CoffeeScript.compile response, bare: true)

And compiled

var read_buffer;

read_buffer = function(buffer, callback) {
  var data;
  data = '';
  buffer.on('readable', function() {
    return data += buffer.read().toString();
  });
  return buffer.on('end', function() {
    return callback(data);
  });
};

http.get('http://i.want.some/stuff', function(res) {
  return read_buffer(res, function(response) {
    return eval(CoffeeScript.compile(response, {
      bare: true
    }));
  });
});

It seems like there may be a issue to dump numpy.int64 into json string in Python 3 and the python team already have a conversation about it. More details can be found here.

There is a workaround provided by Serhiy Storchaka. It works very well so I paste it here:

def convert(o):
    if isinstance(o, numpy.int64): return int(o)  
    raise TypeError

json.dumps({'value': numpy.int64(42)}, default=convert)

This button is a built-in overlay that is provided by the UITextField class, but as of the iOS 2.2 SDK, there isn't any way to set it via Interface Builder. You have to enable it programmatically.

Add this line of code somewhere (viewDidLoad, for example):

Objective-C

myUITextField.clearButtonMode = UITextFieldViewModeWhileEditing;

Swift 5.0

myUITextField.clearButtonMode = .whileEditing

Try to use the <font> tag

?<table> 
    <thead> 
        <tr> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
            <th><font color="#FFF">Header 1</font></th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

But I think this should work, too:

?<table> 
    <thead> 
        <tr> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
            <th color="#FFF">Header 1</th> 
        </tr> 
    </thead> 
    <tbody> 
        <tr> 
            <td>blah blah</td> 
            <td>blah blah</td> 
            <td>blah blah</td> 
        </tr> 
    </tbody> 
</table>

EDIT:

Crossbrowser solution:

use capitals in HEX-color.

<th bgcolor="#5D7B9D" color="#FFFFFF"><font color="#FFFFFF">Header 1</font></th>

There are a few more types than what's listed in the standard name list you've linked to. You can find more in the cryptographic providers documentation. The most common are certainly JKS (the default) and PKCS12 (for PKCS#12 files, often with extension .p12 or sometimes .pfx).

JKS is the most common if you stay within the Java world. PKCS#12 isn't Java-specific, it's particularly convenient to use certificates (with private keys) backed up from a browser or coming from OpenSSL-based tools (keytool wasn't able to convert a keystore and import its private keys before Java 6, so you had to use other tools).

If you already have a PKCS#12 file, it's often easier to use the PKCS12 type directly. It's possible to convert formats, but it's rarely necessary if you can choose the keystore type directly.

In Java 7, PKCS12 was mainly useful as a keystore but less for a truststore (see the difference between a keystore and a truststore), because you couldn't store certificate entries without a private key. In contrast, JKS doesn't require each entry to be a private key entry, so you can have entries that contain only certificates, which is useful for trust stores, where you store the list of certificates you trust (but you don't have the private key for them).

This has changed in Java 8, so you can now have certificate-only entries in PKCS12 stores too. (More details about these changes and further plans can be found in JEP 229: Create PKCS12 Keystores by Default.)

There are a few other keystore types, perhaps less frequently used (depending on the context), those include:

• PKCS11, for PKCS#11 libraries, typically for accessing hardware cryptographic tokens, but the Sun provider implementation also supports NSS stores (from Mozilla) through this.
• BKS, using the BouncyCastle provider (commonly used for Android).
• Windows-MY/Windows-ROOT, if you want to access the Windows certificate store directly.
• KeychainStore, if you want to use the OSX keychain directly.

HTML:

<div class="thumbnail">

CSS:

height: 250px;
}

Found the solution here

Lets say you have span1 as <span id='span1'>my text</span>
text change events can be captured with:

$(document).ready(function(){
    $("#span1").on('DOMSubtreeModified',function(){
         // text change handler
     });

 });
 

I think many of the answers here may be missing a quality method included in StringBuilder: .delete(int start, [int] end). I know this is a late reply; however, this should be made known (and explained a bit more thoroughly).

Let's say you have a StringBuilder table - which you wish to modify, dynamically, throughout your program (one I am working on right now does this), e.g.

StringBuilder table = new StringBuilder();

If you are looping through the method and alter the content, use the content, then wish to discard the content to "clean up" the StringBuilder for the next iteration, you can delete it's contents, e.g.

table.delete(int start, int end). 

start and end being the indices of the chars you wish to remove. Don't know the length in chars and want to delete the whole thing?

table.delete(0, table.length());

NOW, for the kicker. StringBuilders, as mentioned previously, take a lot of overhead when altered frequently (and can cause safety issues with regard to threading); therefore, use StringBuffer - same as StringBuilder (with a few exceptions) - if your StringBuilder is used for the purpose of interfacing with the user.

Try this script to create a temporary table TESTTEST and watch the order of precedence as the triggers are called in this order: 1) INSTEAD OF, 2) FOR, 3) AFTER

All of the logic is placed in INSTEAD OF trigger and I have 2 examples of how you might code some scenarios...

Good luck...

hello i have had same problem an i did the steps with tommer and the problem solved thank you

note :

you don't have to go to that like just do this ;

1)-- Edit your “my.ini” file in c:\xampp\mysql\bin\ Change all default 3306 port entries to a new value 3308

2)--edit your “php.ini” in c:\xampp\php and replace 3306 by 3308

3)--Create the service entry - in Windows command line type

sc.exe create "mysqlweb" binPath= "C:\xampp\mysql\bin\mysqld.exe --defaults-file=c:\xampp\mysql\bin\my.ini mysqlweb"

4)--Open Windows Services and set Startup Type: Automatic, Start the service

you have multiple elements with the same id. That is a big no-no. Make sure your inputs have unique ids.

<td id="pass"><label>Password</label></td>
<tr>
   <td colspan="2"><input class="textBox" id="pass" type="text" maxlength="30" required/></td>
</tr>

see, both the td and the input share the id value pass.

I've read all of the above answers but it seems like they have no common strategy. I found a good article about best practices in Design API from Microsoft Documents. I think you should refer.

In more complex systems, it can be tempting to provide URIs that enable a client to navigate through several levels of relationships, such as /customers/1/orders/99/products. However, this level of complexity can be difficult to maintain and is inflexible if the relationships between resources change in the future. Instead, try to keep URIs relatively simple. Once an application has a reference to a resource, it should be possible to use this reference to find items related to that resource. The preceding query can be replaced with the URI /customers/1/orders to find all the orders for customer 1, and then /orders/99/products to find the products in this order.

.

Tip

Avoid requiring resource URIs more complex than collection/item/collection.

You need to do:

alert($(this).attr('value'));

The problem is that in many cases the packages are multiarch already so the i386 package is not available, but other packages still depend on the i386 package only. This is a problem in the repository, and the managers of the repos should fix it

If you simply need to view the table and run queries on it you can use this third party sdf viewer. It is a lightweight viewer that has all the basic functionalities and is ready to use after install.

and ofcourse, its Free.

This regularly occurs when you change the extension on the JAR for ZIP, extract the zip content and make some modifications on files such as changing the MANIFEST.MF file which is a very common case, many times Eclipse doesn't generate the MANIFEST file as we want, or maybe we would like to modify the CLASS-PATH or the MAIN-CLASS values of it.

The problem occurs when you zip back the folder.

A valid Runnable/Executable JAR has the next structure:

myJAR (Main-Directory)
    |-META-INF (Mandatory)
             |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
    |-com 
         |-MainClass.class (must to implement the main method, mandatory)
    |-properties files (optional)
    |-etc (optional)

If your JAR complies with these rules it will work doesn't matter if you build it manually by using a ZIP tool and then you changed the extension back to .jar

Once you're done try execute it on the command line using:

java -jar myJAR.jar 

When you use a zip tool to unpack, change files and zip again, normally the JAR structure changes to this structure which is incorrect, since another directory level is added on the top of the file system making it a corrupted file as is shown below:

**myJAR (Main-Directory)
    |-myJAR (creates another directory making the file corrupted)**
          |-META-INF (Mandatory)
                   |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
          |-com 
              |-MainClass.class (must to implement the main method, mandatory)
          |-properties files (optional)
          |-etc (optional)

The standard dictionary includes the method setdefault() for retrieving a value and establishing a default if the value does not exist. By contrast, defaultdict lets the caller specify the default up front when the container is initialized.

import collections

def default_factory():
    return 'default value'

d = collections.defaultdict(default_factory, foo='bar')
print 'd:', d
print 'foo =>', d['foo']
print 'bar =>', d['bar']

This works well as long as it is appropriate for all keys to have the same default. It can be especially useful if the default is a type used for aggregating or accumulating values, such as a list, set, or even int. The standard library documentation includes several examples of using defaultdict this way.

$ python collections_defaultdict.py

d: defaultdict(<function default_factory at 0x100468c80>, {'foo': 'bar'})
foo => bar
bar => default value

I just copy the file name Queue.py in the */lib/python2.7/ to queue.py and that solved my problem.

1. You need 3 boundaries for inline images to be fully compliant.

2. Everything goes inside the multipart/mixed.

3. Then use the multipart/related to contain your multipart/alternative and your image attachment headers.

4. Lastly, include your downloadable attachments inside the last boundary of multipart/mixed.

You can use plain javascript - Array.prototype.filter()

$scope.items = $scope.items.filter(function(item) {
    return item.name !== 'ted';
});

It's worth mentioning that detecting an MD5 (which is one of the examples) can be done with:

[0-9a-fA-F]{32}

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

You can use numpy :
flat_list = list(np.concatenate(list_of_list))

You can use this :

Both getSingleResult() and getOneOrNullResult() will throw an exception if there is more than one result. To fix this problem you could add setMaxResults(1) to your query builder.

 $firstSubscriber = $entity->createQueryBuilder()->select('sub')
        ->from("\Application\Entity\Subscriber", 'sub')
        ->where('sub.subscribe=:isSubscribe')
        ->setParameter('isSubscribe', 1)  
        ->setMaxResults(1)
        ->getQuery()
        ->getOneOrNullResult();

value = value.setScale(2, RoundingMode.CEILING)

To select every nth element from any starting position in the vector

nth_element <- function(vector, starting_position, n) { 
  vector[seq(starting_position, length(vector), n)] 
  }

# E.g.
vec <- 1:12

nth_element(vec, 1, 3)
# [1]  1  4  7 10

nth_element(vec, 2, 3)
# [1]  2  5  8 11

I had an application that used a ListPreference where the user was required to select the location of where they wanted to save something.

In that app, I scanned /proc/mounts and /system/etc/vold.fstab for sdcard mount points. I stored the mount points from each file into two separate ArrayLists.

Then, I compared one list with the other and discarded items that were not in both lists. That gave me a list of root paths to each sdcard.

From there, I tested the paths with File.exists(), File.isDirectory(), and File.canWrite(). If any of those tests were false, I discarded that path from the list.

Whatever was left in the list, I converted to a String[] array so it could be used by the ListPreference values attribute.

You can view the code here: http://sapienmobile.com/?p=204

public func jsonPrint(_ o: NSObject, spacing: String = "", after: String = "", before: String = "") {
    let newSpacing = spacing + "    "
    if o.isArray() {
        print(before + "[")
        if let a = o as? Array<NSObject> {
            for object in a {
                jsonPrint(object, spacing: newSpacing, after: object == a.last! ? "" : ",", before: newSpacing)
            }
        }
        print(spacing + "]" + after)
    } else {
        if o.isDictionary() {
            print(before + "{")
            if let a = o as? Dictionary<NSObject, NSObject> {
                for (key, val) in a {
                    jsonPrint(val, spacing: newSpacing, after: ",", before: newSpacing + key.description + " = ")
                }
            }
            print(spacing + "}" + after)
        } else {
            print(before + o.description + after)
        }
    }
}

This one is pretty close to original Objective-C print style

While trace flag 272 may work for many, it definitely won't work for hosted Sql Server Express installations. So, I created an identity table, and use this through an INSTEAD OF trigger. I'm hoping this helps someone else, and/or gives others an opportunity to improve my solution. The last line allows returning the last identity column added. Since I typically use this to add a single row, this works to return the identity of a single inserted row.

The identity table:

CREATE TABLE [dbo].[tblsysIdentities](
[intTableId] [int] NOT NULL,
[intIdentityLast] [int] NOT NULL,
[strTable] [varchar](100) NOT NULL,
[tsConcurrency] [timestamp] NULL,
CONSTRAINT [PK_tblsysIdentities] PRIMARY KEY CLUSTERED 
(
    [intTableId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,  ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

and the insert trigger:

-- INSERT --
IF OBJECT_ID ('dbo.trgtblsysTrackerMessagesIdentity', 'TR') IS NOT NULL
   DROP TRIGGER dbo.trgtblsysTrackerMessagesIdentity;
GO
CREATE TRIGGER trgtblsysTrackerMessagesIdentity
ON dbo.tblsysTrackerMessages
INSTEAD OF INSERT AS 
BEGIN
    DECLARE @intTrackerMessageId INT
    DECLARE @intRowCount INT

    SET @intRowCount = (SELECT COUNT(*) FROM INSERTED)

    SET @intTrackerMessageId = (SELECT intIdentityLast FROM tblsysIdentities WHERE intTableId=1)
    UPDATE tblsysIdentities SET intIdentityLast = @intTrackerMessageId + @intRowCount WHERE intTableId=1

    INSERT INTO tblsysTrackerMessages( 
    [intTrackerMessageId],
    [intTrackerId],
    [strMessage],
    [intTrackerMessageTypeId],
    [datCreated],
    [strCreatedBy])
    SELECT @intTrackerMessageId + ROW_NUMBER() OVER (ORDER BY [datCreated]) AS [intTrackerMessageId], 
    [intTrackerId],
   [strMessage],
   [intTrackerMessageTypeId],
   [datCreated],
   [strCreatedBy] FROM INSERTED;

   SELECT TOP 1 @intTrackerMessageId + @intRowCount FROM INSERTED;
END

This works well for specific articles where the text is all wrapped in <p> tags. Since the web is an ugly place, it's not always the case.

Often, websites will have text scattered all over, wrapped in different types of tags (e.g. maybe in a <span> or a <div>, or an <li>).

To find all text nodes in the DOM, you can use soup.find_all(text=True).

This is going to return some undesired text, like the contents of <script> and <style> tags. You'll need to filter out the text contents of elements you don't want.

blacklist = [
  'style',
  'script',
  # other elements,
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name not in blacklist]

If you are working with a known set of tags, you can tag the opposite approach:

whitelist = [
  'p'
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name in whitelist]

No need for extra software. Use the task scheduler -> create task -> hidden. The checkbox for hidden is in the bottom left corner. Set the task to trigger on login (or whatever condition you like) and choose the task in the actions tab. Running it hidden ensures that the task runs silently in the background like a service.

Note that you must also set the program to run "whether the user is logged in or not" or the program will still run in the foreground.

Yea, Indeed @Evert answer is perfectly correct. In addition I'll like to add one more reason that could encounter such error.

>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,200))])

This will be perfectly fine, However, This leads to error:

>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,201))])

ValueError: could not broadcast input array from shape (20,200) into shape (20)

The numpy arry within the list, must also be the same size.

In summary:

Option#1: Use reflection to apply font (combining weston & Roger Huang's answer):

import java.lang.reflect.Field;
import android.content.Context;
import android.graphics.Typeface;

public final class FontsOverride { 

    public static void setDefaultFont(Context context,
            String staticTypefaceFieldName, String fontAssetName) {
        final Typeface regular = Typeface.createFromAsset(context.getAssets(),
                fontAssetName);
        replaceFont(staticTypefaceFieldName, regular);
    } 

    protected static void replaceFont(String staticTypefaceFieldName,final Typeface newTypeface) {
        if (isVersionGreaterOrEqualToLollipop()) {
            Map<String, Typeface> newMap = new HashMap<String, Typeface>();
            newMap.put("sans-serif", newTypeface);
            try {
                final Field staticField = Typeface.class.getDeclaredField("sSystemFontMap");
                staticField.setAccessible(true);
                staticField.set(null, newMap);
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }
        } else {
            try {
                final Field staticField = Typeface.class.getDeclaredField(staticTypefaceFieldName);
                staticField.setAccessible(true);
                staticField.set(null, newTypeface);
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } 
        }
    }

} 

Usage in Application class:

public final class Application extends android.app.Application {
    @Override 
    public void onCreate() { 
        super.onCreate(); 
        FontsOverride.setDefaultFont(this, "DEFAULT", "MyFontAsset.ttf");
        FontsOverride.setDefaultFont(this, "MONOSPACE", "MyFontAsset2.ttf");
        FontsOverride.setDefaultFont(this, "SERIF", "MyFontAsset3.ttf");
        FontsOverride.setDefaultFont(this, "SANS_SERIF", "MyFontAsset4.ttf");
    } 
} 

set up a style to force that font typeface application wide (based on lovefish):

Pre-Lollipop:

<resources>
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    </style>

   <!-- Application theme. -->
   <style name="AppTheme" parent="AppBaseTheme">
       <item name="android:typeface">monospace</item>
   </style>
</resources>

Lollipop (API 21):

<resources>
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    </style>

   <!-- Application theme. -->
   <style name="AppTheme" parent="AppBaseTheme">
       <item name="android:textAppearance">@style/CustomTextAppearance</item>
   </style>

   <style name="CustomTextAppearance">
       <item name="android:typeface">monospace</item>
   </style>
</resources>

Option2: Subclass each and every View where you need to customize font, ie. ListView, EditTextView, Button, etc. (Palani's answer):

public class CustomFontView extends TextView {

public CustomFontView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init(); 
} 

public CustomFontView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init(); 
} 

public CustomFontView(Context context) {
    super(context);
    init(); 
} 

private void init() { 
    if (!isInEditMode()) {
        Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "Futura.ttf");
        setTypeface(tf);
    } 
} 

Option 3: Implement a View Crawler that traverses through the view hierarchy of your current screen:

Variation#1 (Tom's answer):

public static final void setAppFont(ViewGroup mContainer, Typeface mFont, boolean reflect)
{ 
    if (mContainer == null || mFont == null) return;

    final int mCount = mContainer.getChildCount();

    // Loop through all of the children. 
    for (int i = 0; i < mCount; ++i)
    { 
        final View mChild = mContainer.getChildAt(i);
        if (mChild instanceof TextView)
        { 
            // Set the font if it is a TextView. 
            ((TextView) mChild).setTypeface(mFont);
        } 
        else if (mChild instanceof ViewGroup)
        { 
            // Recursively attempt another ViewGroup. 
            setAppFont((ViewGroup) mChild, mFont);
        } 
        else if (reflect)
        { 
            try { 
                Method mSetTypeface = mChild.getClass().getMethod("setTypeface", Typeface.class);
                mSetTypeface.invoke(mChild, mFont); 
            } catch (Exception e) { /* Do something... */ }
        } 
    } 
} 

Usage :

final ViewGroup mContainer = (ViewGroup) findViewById(
android.R.id.content).getRootView();
HomeActivity.setAppFont(mContainer, Typeface.createFromAsset(getAssets(),
"fonts/MyFont.ttf"));

Variation#2: https://coderwall.com/p/qxxmaa/android-use-a-custom-font-everywhere.

Option #4: Use 3rd Party Lib called Calligraphy.

Personally, I would recommend Option#4, as it saves a lot of headaches.

The short answer is "yes". A sample ldapsearch command to query an Active Directory server is:

ldapsearch \
    -x -h ldapserver.mydomain.com \
    -D "[email protected]" \
    -W \
    -b "cn=users,dc=mydomain,dc=com" \
    -s sub "(cn=*)" cn mail sn

This would connect to an AD server at hostname ldapserver.mydomain.com as user [email protected], prompt for the password on the command line and show name and email details for users in the cn=users,dc=mydomain,dc=com subtree.

See Managing LDAP from the Command Line on Linux for more samples. See LDAP Query Basics for Microsoft Exchange documentation for samples using LDAP queries with Active Directory.

Try with:

$foo2 = array_slice($foo, 1);

If you just want to get the path to a certain action, use UrlHelper:

UrlHelper u = new UrlHelper(this.ControllerContext.RequestContext);
string url = u.Action("About", "Home", null);

if you want to create a hyperlink:

string link = HtmlHelper.GenerateLink(this.ControllerContext.RequestContext, System.Web.Routing.RouteTable.Routes, "My link", "Root", "About", "Home", null, null);

Intellisense will give you the meaning of each of the parameters.

Update from comments: controller already has a UrlHelper:

string url = this.Url.Action("About", "Home", null); 

One of these will work...

<head>_x000D_
  <meta http-equiv='refresh' content='0; URL=http://example.com/'>_x000D_
</head>

...or it can done with JavaScript:

window.location.href = 'https://example.com/';

REPLACE(REPLACE(a.CUST_ADDRESS1,CHR(10),' '),CHR(13),' ') as ADDRESS

Go to Start → Control Panel → System → Advanced system settings → advanced(tab) → Environment Variables → System Variables → New:

Variable name: _JAVA_OPTIONS
Variable value: -Xmx512M

Use Calendar

Calendar.getInstance().get(Calendar.MILLISECOND);

or

Calendar c=Calendar.getInstance();
c.setTime(new Date()); /* whatever*/
//c.setTimeZone(...); if necessary
c.get(Calendar.MILLISECOND);

In practise though I think it will nearly always equal System.currentTimeMillis()%1000; unless someone has leap-milliseconds or some calendar is defined with an epoch not on a second-boundary.

May be you are using wrong mysql_connector.

Use connector of same mysql version

You can also add a CALayer to the button - you can do lots of things with these including a color overlay, this example uses a plain color layer you can also easily graduate the colour. Be aware though added layers obscure those underneath

+(void)makeButtonColored:(UIButton*)button color1:(UIColor*) color
{

    CALayer *layer = button.layer;
    layer.cornerRadius = 8.0f;
    layer.masksToBounds = YES;
    layer.borderWidth = 4.0f;
    layer.opacity = .3;//
    layer.borderColor = [UIColor colorWithWhite:0.4f alpha:0.2f].CGColor;

    CAGradientLayer *colorLayer = [CAGradientLayer layer];
    colorLayer.cornerRadius = 8.0f;
    colorLayer.frame = button.layer.bounds;
    //set gradient colors
    colorLayer.colors = [NSArray arrayWithObjects:
                         (id) color.CGColor,
                         (id) color.CGColor,
                         nil];

    //set gradient locations
    colorLayer.locations = [NSArray arrayWithObjects:
                            [NSNumber numberWithFloat:0.0f],
                            [NSNumber numberWithFloat:1.0f],
                            nil];


    [button.layer addSublayer:colorLayer];

}

The best/easy/fast solution that you can use if it's a quick debugging, is to surround your code with catching exceptions. That's what I'm doing when I want to check something fast in production.

try {
    // Page code
}
catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

JavaScript has a RegExp object which does what you want. The String object has a match() function that will help you out.

var matches = text.match(/price\[(\d+)\]\[(\d+)\]/);
var productId = matches[1];
var shopId    = matches[2];

Make sure first that your $siteLink_val isn't returning white space as a value. The <textarea> element by default has an empty value so if the variable you're echo'ing for some reason has spaces, there's your problem right off the bat.

To make the code the absolute cleanest, I would suggest you could do something like this, allowing for some more flexibility later. I've made a function that returns either a NULL if the variable isn't present (what you seem to be aiming for in the original post) and the absolute value otherwise. Once you've made sure of your variable's contents, try this:

function build_siteLink_val() {
     if ( $siteLink_val ) {
          return $siteLink_val;
     }

     else {
          return "";
     }
}

$output_siteLink_val = build_siteLink_val();

And the following code in your textarea would now read:

<textarea style="width:350px; height:80px;" cols="42" rows="5" name="sitelink"><?=$output_siteLink_val?></textarea>

This is assuming your PHP install is configured for short-hand variable calls, as seen in the shortened "<?=?>" tags. If you cannot output this way, remember to preface your PHP code with "<?php" and close with "?>".

Avoid line breaks between <textarea>'s because it can create the potential of erroneous characters.

Also, check your CSS to make sure there isn't a padding rule pushing text inward.

Also, you specify a cols and rows value on the textarea, and then style a width and height. These rules are counter-productive, and will result in inconsistent visuals. Stick with either defining the size through style (I recommend giving the element a class) or the rows/cols.

I had this edge case, where I checked out a previous version of the code in which my file directory structure was different:

git checkout 1.87.1                                    
warning: unable to unlink web/sites/default/default.settings.php: Permission denied
... other warnings ...
Note: checking out '1.87.1'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. 
Example:

  git checkout -b <new-branch-name>

HEAD is now at 50a7153d7... Merge branch 'hotfix/1.87.1'

In a case like this you may need to use --force (when you know that going back to the original branch and discarding changes is a safe thing to do).

git checkout master did not work:

$ git checkout master
error: The following untracked working tree files would be overwritten by checkout:
web/sites/default/default.settings.php
... other files ...

git checkout master --force (or git checkout master -f) worked:

git checkout master -f
Previous HEAD position was 50a7153d7... Merge branch 'hotfix/1.87.1'
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.

I've created the following script and it worked for me just fine.

#! /bin/sh
cd $(dirname $0)
DB=$1
DBUSER=$2
DBPASSWD=$3
FILE=$DB-$(date +%F).sql
mysqldump --routines "--user=${DBUSER}"  --password=$DBPASSWD $DB > $PWD/$FILE
gzip $FILE
echo Created $PWD/$FILE*

and you call the script using command line arguments.

backupdb.sh my_db dev_user dev_password

For me it was caused by insufficient free space on hard drive.

Probably the best reason is because 0xfffffffffffffff/15 would give you a horribly wrong answer...

You need to use a graphics library. Put this in your preamble:

\usepackage{graphicx}

You can then add images like this:

\begin{figure}[ht!]
\centering
\includegraphics[width=90mm]{fixed_dome1.jpg}
\caption{A simple caption \label{overflow}}
\end{figure}

This is the basic template I use in my documents. The position and size should be tweaked for your needs. Refer to the guide below for more information on what parameters to use in \figure and \includegraphics. You can then refer to the image in your text using the label you gave in the figure:

And here we see figure \ref{overflow}.

Read this guide here for a more detailed instruction: http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

Use:

git diff 15dc8^!

as described in the following fragment of git-rev-parse(1) manpage (or in modern git gitrevisions(7) manpage):

Two other shorthands for naming a set that is formed by a commit and its parent commits exist. The r1^@ notation means all parents of r1. r1^! includes commit r1 but excludes all of its parents.

This means that you can use 15dc8^! as a shorthand for 15dc8^..15dc8 anywhere in git where revisions are needed. For diff command the git diff 15dc8^..15dc8 is understood as git diff 15dc8^ 15dc8, which means the difference between parent of commit (15dc8^) and commit (15dc8).

^{Note: the description in git-rev-parse(1) manpage talks about revision ranges, where it needs to work also for merge commits, with more than one parent. Then r1^! is "r1 --not r1^@" i.e. "r1 ^r1^1 ^r1^2 ..."}

Also, you can use git show COMMIT to get commit description and diff for a commit. If you want only diff, you can use git diff-tree -p COMMIT

var list = new List<string>();
var queryable = list.AsQueryable();

Try this when i tried giving muted , check this demo in codpen

    <video width="320" height="240" controls autoplay muted id="videoId">

</video>

script

function toggleMute() {

  var video=document.getElementById("videoId");

  if(video.muted){

You would be able to get at least temporary created copy of the file path on your machine. The only condition here is your input element should be within a form What you have to do else is putting in the form an attribute enctype, e.g.:

<form id="formid" enctype="multipart/form-data" method="post" action="{{url('/add_a_note' )}}">...</form>

you can find the path string at the bottom. It opens stream to file and then deletes it.
