I am now using Xcode 11.6, macOS 10.15.6, and iOS 13.5.1.

First the problem was that I was on Xcode 11.4. But I couldn't upgrade since I wasn't on macOS v10.15 (Catalina) yet. (And I couldn't upgrade because my RAID went down and I couldn't make a backup, but that's another saga.)

After upgrading to Catalina, then to Xcode 11.6 I still couldn't build to the device. So I opened Devices and Simulators and unpaired the phone, as mentioned in the comments here. Then when I tried to re-pair, a warning message said that the device was busy (it was not). Finally, after rebooting the phone (had to untether it for it to come back on), cleaning Xcode, and re-pairing the phone, I finally, finally built to the device. So good luck!

I think it is better to update your "mysql-connector" lib package, so database can be still more safe.

I am using mysql of version 8.0.12. When I updated the mysql-connector-java to version 8.0.11, the problem was gone.

I have MYSQL on server and nodejs application on another server

Execute the following query in MYSQL Workbench

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'password'

The following code worked for me:

echo userInput

I suspect that the jar files of hibernate-core and hibernate-entitymanager dependencies are corrupted or were not installed properly on your machine.

I suggest that you just delete the folders named hibernate-core and hibernate-entitymanager from your Maven local repository and Maven will reinstall them.

The default location for Maven local repository is C:\Documents and Settings\[USERNAME]\.m2 in windows or ~/.m2 in Linux/Mac.

Since you are using Android < 5.0 you can't use the default adb reverse method, but Facebook has added official documentation to connect to the development server via Wi-Fi, which would support your version. Quoting the instructions for MacOS, but they also have them for Linux and Windows:

Method 2: Connect via Wi-Fi

You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.

You can find the IP address in System Preferences ? Network.

Make sure your laptop and your phone are on the same Wi-Fi network. Open your React Native app on your device. You'll see a red screen with an error. This is OK. The following steps will fix that. Open the in-app Developer menu. Go to Dev Settings ? Debug server host for device. Type in your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081). Go back to the Developer menu and select Reload JS.

I had a semicolon at the end, and gave me this error.

Either you experienced database connection issue or you missed any of the hibernate configurations to connect to database such as database DIALECT.

Happens if your database server was disconnected due to network related issue.

If you're using spring boot along with hibernate connected to Oracle Db, use

hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true
entitymanager.packagesToScan: com

As the official docs of redux suggest, better to export the unconnected component as well.

In order to be able to test the App component itself without having to deal with the decorator, we recommend you to also export the undecorated component:

import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
 
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)

Since the default export is still the decorated component, the import statement pictured above will work as before so you won't have to change your application code. However, you can now import the undecorated App components in your test file like this:

// Note the curly braces: grab the named export instead of default export
import { App } from './App'

And if you need both:

import ConnectedApp, { App } from './App'

In the app itself, you would still import it normally:

import App from './App'

You would only use the named export for tests.

This is probably due to its lack of connections to the Hive Meta Store,my hive Meta Store is stored in Mysql,so I need to visit Mysql,So I add a dependency in my build.sbt

libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.38"

and the problem is solved!

You should install PDO on your server. Edit your php.ini (look at your phpinfo(), "Loaded Configuration File" line, to find the php.ini file path). Find and uncomment the following line (remove the ; character):

;extension=pdo_mysql.so

Then, restart your Apache server. For more information, please read the documentation.

For me, adding Trusted_Connection=True to the connection string helped.

Please add this block inside android in build.gradle

dexOptions { preDexLibraries = false }

From stack trace:

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

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

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

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

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

var mysql = require('mysql');

var pool  = mysql.createPool({

If you are in a network with multiple docker containers, make sure they are all up and running! One of my containers was down, pretty obvious if you know where to check.

If you are in Android Studio Open Terminal

 adb kill-server

press enter and again

 adb start-server

press enter

Otherwise

Open Command prompt and got android

sdk>platform-tools> adb kill-server

press enter

and again

adb start-server

press enter

One more reason for this error (assuming that gradle properly setup) is incompatibility between andorid.gradle tools and gradle itself - check out this answer for the complete compatibility table.

In my case the error was the same as in the question and the stacktrace as following:

I've fixed that by upgrading com.android.tools.build:gradle to the current latest 3.1.4

buildscript {
    repositories {
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
    }
}

Gradle version is 4.6

I had the same issue.

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

This solved my problem

I would like to add a resolution that worked for me. Setup: Oracle 11g 64 bits running on Windows 2008 R2 (64 bits OS)

Client is a .net framework 3.5 application (ported from 2.0) compiled with x86 platform setting.

I had the exact same issue of BadImageFormatException. Compiling to 64 bits eliminates the exception but it was not an option for me as my app is using 32 bits activex components who do not work in 64 bits.

I solved the issue by downloading Oracle Instant Client 11 (this is just a bunch of DLL than can be xcopied) from Oracle website, and copying the files in my application files directory. See here : http://www.oracle.com/technetwork/database/features/oci/instant-client-wp-131479.pdf

This has solved the issue, from ProcMon tool I can see that the locally copied oci.dll gets loaded by System.Data.OracleClient and everything is fine.

It could probably be done by changing environment settings like proposed above, but this method has the advantage of not altering any settings on the server configuration.

just install ojdbc-full, That contains the 12.1.0.1 release.

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

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

I assume that boot is configuring the DataSource for you. In this case, and since you are using MySQL, you can add the following to your application.properties up to 1.3

spring.datasource.testOnBorrow=true
spring.datasource.validationQuery=SELECT 1

As djxak noted in the comment, 1.4+ defines specific namespaces for the four connections pools Spring Boot supports: tomcat, hikari, dbcp, dbcp2 (dbcp is deprecated as of 1.5). You need to check which connection pool you are using and check if that feature is supported. The example above was for tomcat so you'd have to write it as follows in 1.4+:

spring.datasource.tomcat.testOnBorrow=true 
spring.datasource.tomcat.validationQuery=SELECT 1

Note that the use of autoReconnect is not recommended:

The use of this feature is not recommended, because it has side effects related to session state and data consistency when applications don't handle SQLExceptions properly, and is only designed to be used when you are unable to configure your application to handle SQLExceptions resulting from dead and stale connections properly.

I faced the same situation. Create your connection string as follows.

Replace

"connectionString": "Data Source=server name;Initial Catalog=DB name;User id=user id;Password=password;Integrated Security=True;MultipleActiveResultSets=True"

by

"connectionString": "Server=server name; Database=Treat; User Id=user id; Password=password; Trusted_Connection=False; MultipleActiveResultSets=true"

I use sprint-boot (2.1.1), and mysql version is 8.0.13. I add dependency in pom, solve my problem.

 <dependency>
      <groupId>mysql</groupId>

      <version>8.0.13</version>
 </dependency>

In Android 8.1 it is must to turned Location on to get SSID, if not you can get connection state but not SSID

WifiManager wifiManager = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = null;
if (wifiManager != null) 
wifiInfo = wifiManager.getConnectionInfo();
 String ssid = null;
if (wifiInfo != null) 
ssid = wifiInfo.getSSID(); /*you will get SSID <unknown ssid> if location turned off*/

Just for others getting this error and looking for info on it, it is also thrown if you happen to pass a binding parameter and then never use it. I couldn't really find that stated clearly anywhere but had to prove it through trial and error.

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

I had the same error. I deleted the android repository from android sdk manager and reinstalled it. It worked.

You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.

A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.

If you encounter this error in GoDaddy after deploying a .Net MVC web application..And your web.config is absolutely correct... Right click your data project select settings and make sure that the correct connection strings to the GoDaddy server is in use

The database must have a name (example DB1), try this one:

OracleConnection con = new OracleConnection("data source=DB1;user id=fastecit;password=fastecit"); 

In case the TNS is not defined you can also try this one:

OracleConnection con = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=DB1)));
User Id=fastecit;Password=fastecit"); 

To simulate a dropped connection try

connection.destroy();

In the event that anyone would be interested. Here's a quick shell script that will remove all local branches that aren't tracked remotely. A word of caution: This will get rid of any branch that isn't tracked remotely regardless of whether it was merged or not.

If you guys see any issues with this please let me know and I'll fix it (etc. etc.)

Save it in a file called git-rm-ntb (call it whatever) on PATH and run:

git-rm-ntb <remote1:optional> <remote2:optional> ...

clean()
{
  REMOTES="$@";
  if [ -z "$REMOTES" ]; then
    REMOTES=$(git remote);
  fi
  REMOTES=$(echo "$REMOTES" | xargs -n1 echo)
  RBRANCHES=()
  while read REMOTE; do
    CURRBRANCHES=($(git ls-remote $REMOTE | awk '{print $2}' | grep 'refs/heads/' | sed 's:refs/heads/::'))
    RBRANCHES=("${CURRBRANCHES[@]}" "${RBRANCHES[@]}")
  done < <(echo "$REMOTES" )
  [[ $RBRANCHES ]] || exit
  LBRANCHES=($(git branch | sed 's:\*::' | awk '{print $1}'))
  for i in "${LBRANCHES[@]}"; do
    skip=
    for j in "${RBRANCHES[@]}"; do
      [[ $i == $j ]] && { skip=1; echo -e "\033[32m Keeping $i \033[0m"; break; }
    done
    [[ -n $skip ]] || { echo -e "\033[31m $(git branch -D $i) \033[0m"; }
  done

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

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

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

I had a similiar problem that caused me some hours of headache.

My repository method was:

public List<ResultClass> findAllByTypeAndObjects(String type, List<Object> objects);

I got the error, that the property type was not found for type ResultClass.

The solution was, that jpa/hibernate does not support plurals? Nevertheless, removing the 's' solved the problem:

public List<ResultClass> findAllByTypeAndObject(String type, List<Object>

A bit optimized(for me atleast) solution. write this to a file db.js and require this to wherever required and call it with a function call and you are good to go.

   const MongoClient = require('mongodb').MongoClient;
    async function getConnections(url,db){
        return new Promise((resolve,reject)=>{
            MongoClient.connect(url, { useUnifiedTopology: true },function(err, client) {
                if(err) { console.error(err) 
                    resolve(false);
                }
                else{
                    resolve(client.db(db));
                }
            })
        });
    }

    module.exports = async function(){
        let dbs      = [];
        dbs['db1']     = await getConnections('mongodb://localhost:27017/','db1');
        dbs['db2']     = await getConnections('mongodb://localhost:27017/','db2');
        return dbs;
    };

I recompiled the package specification, even though the change was only in the package body. This resolved my issue

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

There is another way to throw this error.

Keep in mind that the path to the model is case sensitive.

In this similar example involving the "Category" model, the error was thrown under these conditions:

1) The require statement was mentioned in two files: ..category.js and ..index.js 2) I the first, the case was correct, in the second file it was not as follows:

category.js

index.js

This happened to me after a java update, few things to check if you are sure your path has been set before:

1. if the path doesn't match the latest java install folder, change it (if your in eclipse check the eclipse.ini too to make sure your using your systems default vm (ie no VM tag) )

2. go to the java directory, there should be a 'jdk' and a 'jre' in the path, for example:

   C:\Program Files (x86)\Java\jdk1.8.0_72\jre
   

   if not you probably installed the JRE only not the JDK that

3. finally if the lib folder of the jdk (not jre) doesnt contain tools.jar then you have a problem with the install

I have also receive the same IOException, but I find the Android system demo: "BluetoothChat" project is worked. I determined the problem is the UUID.

So i replace my UUID.fromString("00001001-0000-1000-8000-00805F9B34FB") to UUID.fromString("8ce255c0-200a-11e0-ac64-0800200c9a66") and it worked most scene,only sometimes need to restart the Bluetooth device;

I know this is an old post, but I ran into this same issue with my VMs. Log into the VM and go to Control Panel > System and Security > Windows Firewall > Allowed Apps. Then check all of the boxes next to "File and Printer Sharing" to enable file sharing. This should allow you to ping the VM. The screenshot below is from a 2016 Windows Server but the same method will work on older ones.

My oracle stopped working and I was getting this error. I restarted my machine and also tried above solutions. Ultimately, I opened component services and restarted the oracle services and it all started working. Hope this helps someone.

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

Function adoIsConnected(adoCn As ADODB.Connection) As Boolean

    '----------------------------------------------------------------
    '#PURPOSE: Checks whether the supplied db connection is alive and
    '          hasn't had it's TCP connection forcibly closed by remote
    '          host, for example, as happens during an undock event
    '#RETURNS: True if the supplied db is connected and error-free, 
    '          False otherwise
    '#AUTHOR:  Belladonna
    '----------------------------------------------------------------

    Dim i As Long
    Dim cmd As New ADODB.Command

    'Set up SQL command to return 1
    cmd.CommandText = "SELECT 1"
    cmd.ActiveConnection = adoCn

    'Run a simple query, to test the connection
    On Error Resume Next
    i = cmd.Execute.Fields(0)
    On Error GoTo 0

    'Tidy up
    Set cmd = Nothing

    'If i is 1, connection is open
    If i = 1 Then
        adoIsConnected = True
    Else
        adoIsConnected = False
    End If

End Function

in my case adding <clear /> just after <connectionStrings> worked like charm

Connect to Sqlite3 via ADB Shell

I haven't found any way to do that in Android Studio, but I access the db with a remote shell instead of pulling the file each time.

Find all info here: http://developer.android.com/tools/help/adb.html#sqlite

1- Go to your platform-tools folder in a command prompt

2- Enter the command adb devices to get the list of your devices

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb devices
List of devices attached
emulator-xxxx   device

3- Connect a shell to your device:

C:\Android\adt-bundle-windows-x86_64\sdk\platform-tools>adb -s emulator-xxxx shell

4- Navigate to the folder containing your db file:

cd data/data/<your-package-name>/databases/

5- run sqlite3 to connect to your db:

sqlite3 <your-db-name>.db

6- run sqlite3 commands that you like eg:

Select * from table1 where ...;

Note: Find more commands to run below.

SQLite cheatsheet

There are a few steps to see the tables in an SQLite database:

1. List the tables in your database:

   .tables
   

2. List how the table looks:

   .schema tablename
   

3. Print the entire table:

   SELECT * FROM tablename;
   

4. List all of the available SQLite prompt commands:

   .help
   

If you got the error in your IDE(compile-time error), you need to add your mysql-connector jar file to your libs and add this to your referenced library of project too.

If you get this error when you are running it, then probably its because you have not included mysql-connector JAR file to your webserver's lib folder.

Add mysql-connector-java-5.1.25-bin.jar to your classpath and also to your webserver's lib directory. Tomcat lib path is given as an example Tomcat 6.0\lib

You need to make sure the IIS Management Console is installed.

A "little" late to the party but the real answer to this - if you use Oracle.ManagedDataAccess ODP.NET provider, you should forget about things like network\admin, Oracle client, Oracle_Home, etc.

Here is what you need

1. Download and install Oracle Developer Tools for VS or ODAC. Note - Dev tools will install ODAC for you. This will create relatively small installation under C:\Program Files (x86). With full dev tools, under 60Mb
2. In your project you will install Nuget package with corresponding version of ODP.net (Oracle.ManagedDataAccess.dll) which you will reference

3. At this point you have 2 options to connect.

   • a) In the connection string set datasource in the following format

     DataSource=ServerName:Port/SID . . . or DataSource=IP:Port/SID . . .

   • b) Create tnsnames.ora file (only it is going to be different from previous experiences). Have entry in it:

     AAA = (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = ServerNameOrIP)(PORT = 1521))
     (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = SIDNAME)))

     And place this file into your bin folder, where your application is running from. Now you can connect using your connection name - DataSource=AAA . . . So, even though you have tnsnames.ora, with ODP.net managed it works a bit different - you create local TNS file. And now, it is easy to manage it.

To summarize - with managed, no need for heavy Oracle Client, Oracle_home or knowing depths of oracle installation folders. Everything can be done within your .net application structures.

Note to under

connetionString =@"server=XXX;Trusted_Connection=yes;database=yourDB;";

Note: XXX = . OR .\SQLEXPRESS OR .\MSSQLSERVER OR (local)\SQLEXPRESS OR (localdb)\v11.0 &...

you can replace 'server' with 'Data Source'

too you can replace 'database' with 'Initial Catalog'

Sample:

 connetionString =@"server=.\SQLEXPRESS;Trusted_Connection=yes;Initial Catalog=books;";

I don't think this is your problem, but it still looks pretty bad to me. You have a duplicate layer of com.examples.quote in your project. Your Activity section in your AndroidManifest.xml should look more like this:

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

You may even have your classes under src/com.example.quotes/com.example.quotes instead of just in com.example.quotes.

I'm not sure if this is causing your problem. But it looks a bit messed up. All your other stuff looks pretty standard to me.

You could use the SizeMode property of the PictureBox Control and set it to Center. This will match the center of your image to the center of your picture box.

pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage;

Hope it could help.

Your chunk size could be too large, have you tried dropping that - maybe 1024 bytes at a time? (also, you could use with to tidy up the syntax)

def DownloadFile(url):
    local_filename = url.split('/')[-1]
    r = requests.get(url)
    with open(local_filename, 'wb') as f:
        for chunk in r.iter_content(chunk_size=1024): 
            if chunk: # filter out keep-alive new chunks
                f.write(chunk)
    return 

Incidentally, how are you deducing that the response has been loaded into memory?

It sounds as if python isn't flushing the data to file, from other SO questions you could try f.flush() and os.fsync() to force the file write and free memory;

    with open(local_filename, 'wb') as f:
        for chunk in r.iter_content(chunk_size=1024): 
            if chunk: # filter out keep-alive new chunks
                f.write(chunk)
                f.flush()
                os.fsync(f.fileno())

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

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

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

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

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

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

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

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

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

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

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

is it possible to export without looping through all records

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

Option Explicit

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

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

I had the same exact problem and my issue was that I had 2 IP addresses from 2 different networks configured in the etc/hosts as below.

10.xxx.x.xxx    localhost
192.xxx.x.xxx   localhost

This should be because there was a conflict as to which IP to be used for the other devices to reach the rmiregistry over the network.

Once I removed the extra-record that is not required, I was able to solve the issue.

So my etc/hosts file had only the following record.

10.xxx.x.xxx    localhost

Search the file my.cnf and comment the line

skip-networking

to

#skip-networking

Restart mysql

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.

Same problem, solved with a simple code refactoring. The problem is sometime present when a required field is null, before do anithing, try to refactor your code. A better workflow can solve the problem.

Have you copied classes12.jar in lib folder of your web application and set the classpath in eclipse.

Go through this link and read and do carefully.

The library should be now referenced in the "Referenced Librairies" under the Package explorer. Now try to run your program again.

leave only one entry for your host IP in /etc/hosts file, it resolved.

I encountered a similar problem when I was using the below to obtain connection factory ConnectionFactory factory = new
ActiveMQConnectionFactory("admin","admin","tcp://:61616");

Its resolved when I changed it to the below

ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://:61616");

The below then showed that my Q size was increasing.. http://:8161/admin/queues.jsp

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

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

Your are good to go after this.

using System; 
using Oracle.DataAccess.Client; 

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

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

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

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

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

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

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

int statusCode = httpClient.executeMethod(postMethod);

Edit

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

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

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

HttpResponse rawResponse = httpclient.execute(postMethod);

If you are connecting a remote mysql server from your local machine using java see the below steps. Error : "java.sql.SQLException: Access denied for user 'xxxxx'@'101.123.163.141' (using password: YES) "

for remote access may be cpanel or others grant the remote access for your local ip address.

In the above error message: "101.123.163.141" is my local machine ip. So First we have to give remote access in the Cpanel-> Remote MySQL®. Then run your application to connect.

Class.forName("com.mysql.jdbc.Driver");  
Connection con=DriverManager.getConnection(  
    "jdbc:mysql://www.xyz.com/abc","def","ghi");  
//here abc is database name, def is username and ghi        
Statement stmt=con.createStatement();  
ResultSet rs=stmt.executeQuery("select * from employee");  
    while(rs.next())  
        System.out.println(rs.getInt(1)+" "+rs.getString(2)+"  
                          "+rs.getString(3));  
con.close();    

Hope it will resolve your issue.

Thanks

Above answers were helpful, but for unknown reasons they did not seem to work. So if you have already installed MySql workbench on your system, instead of downloading the jar files and struggling with the correct version just go to

C:\Program Files (x86)\MySQL\Connector J 8.0

and copy mysql-connector-java-8.0.12 (does not matter what version it is) the jar file in that location and paste it to C:\Program Files\pentaho\design-tools\data-integration\lib

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

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

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

In general, when "Bad File Descriptor" is encountered, it means that the socket file descriptor you passed into the API is not valid, which has multiple possible reasons:

1. The fd is already closed somewhere.
2. The fd has a wrong value, which is inconsistent with the value obtained from socket() api

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

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

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

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

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

There is one interesting option in this scenario I haven`t found in answers here.

You can Nack messages with "requeue" feature in one consumer to process them in another. Generally speaking it is not a right way, but maybe it will be good enough for someone.

https://www.rabbitmq.com/nack.html

And beware of loops (when all concumers nack+requeue message)!

For Drupal 8 users looking for solution for DB import failure:

At end of sql dump file there can commands inserting data to "webprofiler" table. That's I guess some debug log file and is not really important for site to work so all this can be removed. I deleted all those inserts including LOCK TABLES and UNLOCK TABLES (and everything between). It's at very bottom of the sql file. Issue is described here:

https://www.drupal.org/project/devel/issues/2723437

But there is no solution for it beside truncating that table.

BTW I tried all solutions from answers above and nothing else helped.

The PermGen space is what Tomcat uses to store class definitions (definitions only, no instantiations) and string pools that have been interned. From experience, the PermGen space issues tend to happen frequently in dev environments really since Tomcat has to load new classes every time it deploys a WAR or does a jspc (when you edit a jsp file). Personally, I tend to deploy and redeploy wars a lot when I’m in dev testing so I know I’m bound to run out sooner or later (primarily because Java’s GC cycles are still kinda crap so if you redeploy your wars quickly and frequently enough, the space fills up faster than they can manage).

This should theoretically be less of an issue in production environments since you (hopefully) don’t change the codebase on a 10 minute basis. If it still occurs, that just means your codebase (and corresponding library dependencies) are too large for the default memory allocation and you’ll just need to mess around with stack and heap allocation. I think the standards are stuff like:

-XX:MaxPermSize=SIZE

I’ve found however the best way to take care of that for good is to allow classes to be unloaded so your PermGen never runs out:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled

Stuff like that worked magic for me in the past. One thing tho, there’s a significant performance tradeoff in using those, since permgen sweeps will make like an extra 2 requests for every request you make or something along those lines. You’ll need to balance your use with the tradeoffs.

You will have to annotate your service with @Service since you have said I am using annotations for mapping

Here's how you can mock your FileConnection

Mock<IFileConnection> fileConnection = new Mock<IFileConnection>(
                                                           MockBehavior.Strict);
fileConnection.Setup(item => item.Get(It.IsAny<string>,It.IsAny<string>))
              .Throws(new IOException());

Then instantiate your Transfer class and use the mock in your method call

Transfer transfer = new Transfer();
transfer.GetFile(fileConnection.Object, someRemoteFilename, someLocalFileName);

Update:

First of all you have to mock your dependencies only, not the class you are testing(Transfer class in this case). Stating those dependencies in your constructor make it easy to see what services your class needs to work. It also makes it possible to replace them with fakes when you are writing your unit tests. At the moment it's impossible to replace those properties with fakes.

Since you are setting those properties using another dependency, I would write it like this:

public class Transfer
{
    public Transfer(IInternalConfig internalConfig)
    {
        source = internalConfig.GetFileConnection("source");
        destination = internalConfig.GetFileConnection("destination");
    }

    //you should consider making these private or protected fields
    public virtual IFileConnection source { get; set; }
    public virtual IFileConnection destination { get; set; }

    public virtual void GetFile(IFileConnection connection, 
        string remoteFilename, string localFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void PutFile(IFileConnection connection, 
        string localFilename, string remoteFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void TransferFiles(string sourceName, string destName)
    {
        var tempName = Path.GetTempFileName();
        GetFile(source, sourceName, tempName);
        PutFile(destination, tempName, destName);
    }
}

This way you can mock internalConfig and make it return IFileConnection mocks that does what you want.

I had a similar problem with HttpClient version 4.

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

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

Sorry for only commenting in the first place, but i'm posting almost every day a similar comment since many people think that it would be smart to encapsulate ADO.NET functionality into a DB-Class(me too 10 years ago). Mostly they decide to use static/shared objects since it seems to be faster than to create a new object for any action.

That is neither a good idea in terms of peformance nor in terms of fail-safety.

Don't poach on the Connection-Pool's territory

There's a good reason why ADO.NET internally manages the underlying Connections to the DBMS in the ADO-NET Connection-Pool:

In practice, most applications use only one or a few different configurations for connections. This means that during application execution, many identical connections will be repeatedly opened and closed. To minimize the cost of opening connections, ADO.NET uses an optimization technique called connection pooling.

Connection pooling reduces the number of times that new connections must be opened. The pooler maintains ownership of the physical connection. It manages connections by keeping alive a set of active connections for each given connection configuration. Whenever a user calls Open on a connection, the pooler looks for an available connection in the pool. If a pooled connection is available, it returns it to the caller instead of opening a new connection. When the application calls Close on the connection, the pooler returns it to the pooled set of active connections instead of closing it. Once the connection is returned to the pool, it is ready to be reused on the next Open call.

So obviously there's no reason to avoid creating,opening or closing connections since actually they aren't created,opened and closed at all. This is "only" a flag for the connection pool to know when a connection can be reused or not. But it's a very important flag, because if a connection is "in use"(the connection pool assumes), a new physical connection must be openend to the DBMS what is very expensive.

So you're gaining no performance improvement but the opposite. If the maximum pool size specified (100 is the default) is reached, you would even get exceptions(too many open connections ...). So this will not only impact the performance tremendously but also be a source for nasty errors and (without using Transactions) a data-dumping-area.

If you're even using static connections you're creating a lock for every thread trying to access this object. ASP.NET is a multithreading environment by nature. So theres a great chance for these locks which causes performance issues at best. Actually sooner or later you'll get many different exceptions(like your ExecuteReader requires an open and available Connection).

Conclusion:

• Don't reuse connections or any ADO.NET objects at all.
• Don't make them static/shared(in VB.NET)
• Always create, open(in case of Connections), use, close and dispose them where you need them(f.e. in a method)
• use the using-statement to dispose and close(in case of Connections) implicitely

That's true not only for Connections(although most noticable). Every object implementing IDisposable should be disposed(simplest by using-statement), all the more in the System.Data.SqlClient namespace.

All the above speaks against a custom DB-Class which encapsulates and reuse all objects. That's the reason why i commented to trash it. That's only a problem source.

Edit: Here's a possible implementation of your retrievePromotion-method:

public Promotion retrievePromotion(int promotionID)
{
    Promotion promo = null;
    var connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString;
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        var queryString = "SELECT PromotionID, PromotionTitle, PromotionURL FROM Promotion WHERE PromotionID=@PromotionID";
        using (var da = new SqlDataAdapter(queryString, connection))
        {
            // you could also use a SqlDataReader instead
            // note that a DataTable does not need to be disposed since it does not implement IDisposable
            var tblPromotion = new DataTable();
            // avoid SQL-Injection
            da.SelectCommand.Parameters.Add("@PromotionID", SqlDbType.Int);
            da.SelectCommand.Parameters["@PromotionID"].Value = promotionID;
            try
            {
                connection.Open(); // not necessarily needed in this case because DataAdapter.Fill does it otherwise 
                da.Fill(tblPromotion);
                if (tblPromotion.Rows.Count != 0)
                {
                    var promoRow = tblPromotion.Rows[0];
                    promo = new Promotion()
                    {
                        promotionID    = promotionID,
                        promotionTitle = promoRow.Field<String>("PromotionTitle"),
                        promotionUrl   = promoRow.Field<String>("PromotionURL")
                    };
                }
            }
            catch (Exception ex)
            {
                // log this exception or throw it up the StackTrace
                // we do not need a finally-block to close the connection since it will be closed implicitely in an using-statement
                throw;
            }

I had the same error and ended up solving it by upgrading my Oracle ojdbc driver to a version compatible with the Oracle database version

your str_carSql should be exactly like this:

str_carSql = "insert into members_car (car_id, member_id, model, color, chassis_id, plate_number, code) values (@id,@m_id,@model,@color,@ch_id,@pt_num,@code)"

Good Luck

This is how I got rid of the error:

WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=11}

In your nodeconfig.json, the version must be a String, not an integer.

So instead of using "version": 11 use "version": "11" (note the double quotes).

A full example of a working nodecondig.json file for a RemoteWebDriver:

{
  "capabilities":
  [
    {
      "platform": "WIN8_1",
      "browserName": "internet explorer",

If you started it in a terminal you should be ok with a ctrl + 'c' -- this will do a clean shutdown.

However, if you are using launchctl there are specific instructions for that which will vary depending on how it was installed.

If you are using Homebrew it would be launchctl stop homebrew.mxcl.mongodb

truncate tableName

That is what you are looking for.

Truncate will delete all records in the table, emptying it.

something similar happened to me what worked for me was changing the property Integrated Security = True to Integrated Security = false in the web.config of the website

1. First Replace the MySQL dependency as given below

   <dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <version>5.1.44</version>
   </dependency>
   

2. An error showing "Authentication plugin 'caching_sha2_password'" will appear. Run this command:

   mysql -u root -p
   ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
   

On Charles' comment problem: to make things worse, let

:p1 = 'TRIALDEV'

via a Command Parameter, then execute

select T.table_name as NAME, COALESCE(C.comments, '===') as DESCRIPTION
from all_all_tables T
Inner Join all_tab_comments C on T.owner = C.owner and T.table_name = C.table_name
where Upper(T.owner)=:p1
order by T.table_name

558 line(s) affected. Processing time: 00:00:00.6535711

and when changing the literal string from === to ---

select T.table_name as NAME, COALESCE(C.comments, '---') as DESCRIPTION
[...from...same-as-above...]

ORA-01008: not all variables bound

Both statements execute fine in SQL Developer. The shortened code:

            Using con = New OracleConnection(cs)
                con.Open()
                Using cmd = con.CreateCommand()
                    cmd.CommandText = cmdText
                    cmd.Parameters.Add(pn, OracleDbType.NVarchar2, 250).Value = p
                    Dim tbl = New DataTable
                    Dim da = New OracleDataAdapter(cmd)
                    da.Fill(tbl)
                    Return tbl
                End Using
            End Using

using Oracle.ManagedDataAccess.dll Version 4.121.2.0 with the default settings in VS2015 on the .Net 4.61 platform.

So somewhere in the call chain, there might be a parser that is a bit too aggressively looking for one-line-comments started by -- in the commandText. But even if this would be true, the error message "not all variables bound" is at least misleading.

Based on what Warlock wrote, I found that the virtual path root is needed if you aren't hosted at the root of your web. (This works for MVC Web API controllers)

String baseUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority) 
+ Configuration.VirtualPathRoot;

From Android perspective: Method not available in api version

I was getting this Issue primarily because i was using some thing that is not available/deprecated in that Android version

Wrong way:

Notification.Builder nBuilder = new Notification.Builder(mContext);
nBuilder.addAction(new Notification.Action(android.R.drawable.ic_menu_view,"PAUSE",pendingIntent));

Right way:

Notification.Builder nBuilder = new Notification.Builder(mContext);
nBuilder.addAction(android.R.drawable.ic_media_pause,"PAUSE",pendingIntent);

here Notification.Action is not available prior to API 20 and my min version was API 16

You can use this SpringBeanJobFactory to automatically autowire quartz objects using spring:

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
    ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {
        beanFactory = context.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

Then, attach it to your SchedulerBean (in this case, with Java-config):

@Bean
public SchedulerFactoryBean quartzScheduler() {
    SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();

    ...

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    quartzScheduler.setJobFactory(jobFactory);

    ...

    return quartzScheduler;
}

Working for me, using spring-3.2.1 and quartz-2.1.6.

Check out the complete gist here.

I found the solution in this blog post

I found the solution

since MySQL need the Localhost in-order to work.

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

auto lo
iface lo inet loopback

NOW RESTART the Networking subsystem and the MySQL Services:

sudo /etc/init.d/networking restart

sudo /etc/init.d/mysql restart

Try it now

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

put public, protected or private before the $connection.

I suspect that the line

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

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

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

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

In my case, I had opened a query from data context, like

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)) _

... and then subsequently queried the same...

    Dim stores = DataContext.Stores _
        .Where(Function(d) filter.Contains(d.code)).ToList

Adding the .ToList to the first resolved my issue. I think it makes sense to wrap this in a property like:

Public ReadOnly Property Stores As List(Of Store)
    Get
        If _stores Is Nothing Then
            _stores = DataContext.Stores _
                .Where(Function(d) Filters.Contains(d.code)).ToList
        End If
        Return _stores
    End Get
End Property

Where _stores is a private variable, and Filters is also a readonly property that reads from AppSettings.

Make sure the files are writeable (not read-only), and that your user has write permissions on them.

Also, on most recent systems, the Program Files directory is read-only. Try to place the files in another directory.

For someone looking to solve same by using maven. Add below dependency in POM:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>7.0.0.jre8</version>
</dependency>

And use below code for connection:

String connectionUrl = "jdbc:sqlserver://localhost:1433;databaseName=master;user=sa;password=your_password";

try {
    System.out.print("Connecting to SQL Server ... ");
    try (Connection connection = DriverManager.getConnection(connectionUrl))        {
        System.out.println("Done.");
    }
} catch (Exception e) {
    System.out.println();
    e.printStackTrace();
}

Look for this link for other CRUD type of queries.

Use:

try {

    Class.forName("com.mysql.jdbc.Driver").newInstance();
    System.out.println("Registro exitoso");

} catch (Exception e) {

    System.out.println(e.toString());

}

DriverManager.getConnection(..

Apparently, you did it right. But here is a list of things you'll need with examples from a working application:

1) A context.xml file in META-INF, specifying your data source:

<Context>
    <Resource 
        name="jdbc/DsWebAppDB" 
        auth="Container" 
        type="javax.sql.DataSource" 
        username="sa" 
        password="" 
        driverClassName="org.h2.Driver" 
        url="jdbc:h2:mem:target/test/db/h2/hibernate" 
        maxActive="8" 
        maxIdle="4"/>
</Context>

2) web.xml which tells the container that you are using this resource:

<resource-env-ref>
    <resource-env-ref-name>jdbc/DsWebAppDB</resource-env-ref-name>
    <resource-env-ref-type>javax.sql.DataSource</resource-env-ref-type>
</resource-env-ref>

3) Hibernate configuration which consumes the data source. In this case, it's a persistence.xml, but it's similar in hibernate.cfg.xml

<persistence-unit name="dswebapp">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
        <property name="hibernate.connection.datasource" value="java:comp/env/jdbc/DsWebAppDB"/>
    </properties>
</persistence-unit>

This happens because firewall blocks the database connection.

Disable the firewall and then try running the program again. It worked for me... :D

For the people struggling in Kotlin, it works like this:

lateinit var runnable: Runnable //global variable

 runOnUiThread { //Lambda
            runnable = Runnable {

                //do something here

                runDelayedHandler(5000)
            }
        }

        runnable.run()

 //you need to keep the handler outside the runnable body to work in kotlin
 fun runDelayedHandler(timeToWait: Long) {

        //Keep it running
        val handler = Handler()
        handler.postDelayed(runnable, timeToWait)
    }

You ca also use Response.Write("alert('Error')");

You might also gain a very subsquent performance boost by changing the following Git configuration:

git config --global status.submoduleSummary false

When running the simple git status command on Window 7 x64, it took my computer more than 30 seconds to run. After this option was defined, the command is immediate.

Activating Git's own tracing as explained in the following page helped me found the origin of the problem, which might differ in your installation: https://github.com/msysgit/msysgit/wiki/Diagnosing-why-Git-is-so-slow

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

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

If you have mysqladmin available, you may get the list of queries with:

> mysqladmin -uUSERNAME -pPASSWORD pr

+-----+------+-----------------+--------+---------+------+--------------+------------------+
| Id  | User | Host            | db     | Command | Time | State        | Info             |
+-----+------+-----------------+--------+---------+------+--------------+------------------+
| 137 | beet | localhost:53535 | people | Query   | 292  | Sending data | DELETE FROM      |
| 145 | root | localhost:55745 |        | Query   | 0    |              | show processlist |
+-----+------+-----------------+--------+---------+------+--------------+------------------+

Then you may stop the mysql process that is hosting the long running query:

> mysqladmin -uUSERNAME -pPASSWORD kill 137

Thanks for all answers above, but for me, I can not find Base64Encoder class, so I sort out my way anyway.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        String encoding = DatatypeConverter.printBase64Binary("user:passwd".getBytes("UTF-8"));
        httpGet.setHeader("Authorization", "Basic " + encoding);

        HttpResponse response = Client.execute(httpGet);

        System.out.println("response = " + response);

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String repsonseStr = responseString.toString();

        System.out.println("repsonseStr = " + repsonseStr);

    } catch (IOException e) {
        e.printStackTrace();
    }

}

One more thing, I also tried

Base64.encodeBase64String("user:passwd".getBytes());

It does NOT work due to it return a string almost same with

DatatypeConverter.printBase64Binary()

but end with "\r\n", then server will return "bad request".

Also following code is working as well, actually I sort out this first, but for some reason, it does NOT work in some cloud environment (sae.sina.com.cn if you want to know, it is a chinese cloud service). so have to use the http header instead of HttpClient credentials.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();
        Client.getCredentialsProvider().setCredentials(
                AuthScope.ANY,
                new UsernamePasswordCredentials("user", "passwd")
        );

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        HttpResponse response = Client.execute(httpGet);

        System.out.println("response = " + response);

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String responseStr = responseString.toString();
        System.out.println("responseStr = " + responseStr);

    } catch (IOException e) {
        e.printStackTrace();
    }
}

For me the solution is to kill zombie IIS express worker processes.

e.g. locate in Task Manager and end task.

If your service is going to be part of you application then you are making it way more complex than it needs to be. Since you have a simple use case of getting some data from a RESTful Web Service, you should look into ResultReceiver and IntentService.

This Service + ResultReceiver pattern works by starting or binding to the service with startService() when you want to do some action. You can specify the operation to perform and pass in your ResultReceiver (the activity) through the extras in the Intent.

In the service you implement onHandleIntent to do the operation that is specified in the Intent. When the operation is completed you use the passed in ResultReceiver to send a message back to the Activity at which point onReceiveResult will be called.

So for example, you want to pull some data from your Web Service.

1. You create the intent and call startService.
2. The operation in the service starts and it sends the activity a message saying it started
3. The activity processes the message and shows a progress.
4. The service finishes the operation and sends some data back to your activity.
5. Your activity processes the data and puts in in a list view
6. The service sends you a message saying that it is done, and it kills itself.
7. The activity gets the finish message and hides the progress dialog.

I know you mentioned you didn't want a code base but the open source Google I/O 2010 app uses a service in this way I am describing.

Updated to add sample code:

The activity.

public class HomeActivity extends Activity implements MyResultReceiver.Receiver {

    public MyResultReceiver mReceiver;

    public void onCreate(Bundle savedInstanceState) {
        mReceiver = new MyResultReceiver(new Handler());
        mReceiver.setReceiver(this);
        ...
        final Intent intent = new Intent(Intent.ACTION_SYNC, null, this, QueryService.class);
        intent.putExtra("receiver", mReceiver);
        intent.putExtra("command", "query");
        startService(intent);
    }

    public void onPause() {
        mReceiver.setReceiver(null); // clear receiver so no leaks.
    }

    public void onReceiveResult(int resultCode, Bundle resultData) {
        switch (resultCode) {
        case RUNNING:
            //show progress
            break;
        case FINISHED:
            List results = resultData.getParcelableList("results");
            // do something interesting
            // hide progress
            break;
        case ERROR:
            // handle the error;
            break;
    }
}

The Service:

public class QueryService extends IntentService {
    protected void onHandleIntent(Intent intent) {
        final ResultReceiver receiver = intent.getParcelableExtra("receiver");
        String command = intent.getStringExtra("command");
        Bundle b = new Bundle();
        if(command.equals("query") {
            receiver.send(STATUS_RUNNING, Bundle.EMPTY);
            try {
                // get some data or something           
                b.putParcelableArrayList("results", results);
                receiver.send(STATUS_FINISHED, b)
            } catch(Exception e) {
                b.putString(Intent.EXTRA_TEXT, e.toString());
                receiver.send(STATUS_ERROR, b);
            }    
        }
    }
}

ResultReceiver extension - edited about to implement MyResultReceiver.Receiver

public class MyResultReceiver implements ResultReceiver {
    private Receiver mReceiver;

    public MyResultReceiver(Handler handler) {
        super(handler);
    }

    public void setReceiver(Receiver receiver) {
        mReceiver = receiver;
    }

    public interface Receiver {
        public void onReceiveResult(int resultCode, Bundle resultData);
    }

    @Override
    protected void onReceiveResult(int resultCode, Bundle resultData) {
        if (mReceiver != null) {
            mReceiver.onReceiveResult(resultCode, resultData);
        }
    }
}

Here is my solution.

Tested with IE, Opera, Chrome, FireFox, Safari, as Phonegap WebApp on IOS 8 and as Phonegap WebApp on Android 4.4.2

This solution isn't working with FireFox on localhost.

If you are using (org.springframework.jdbc.datasource.DriverManagerDataSource) in ApplicationContext.xml to specify Database details then use below simple property to specify the schema.

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

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

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

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

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

$stmt->close();

Just a few notes six years later...

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

You bind in onResume but unbind in onDestroy. You should do the unbinding in onPause instead, so that there are always matching pairs of bind/unbind calls. Your intermittent errors will be where your activity is paused but not destroyed, and then resumed again.

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

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

After several strange errors with relative paths in connectionstring I felt the need to post this here.

When using "|DataDirectory|" or "~" you are not allowed to step up and out using "../" !

Example is using several projects accessing the same localdb file placed in one of the projects.

" ~/../other" and " |DataDirectory|/../other" will fail

Even if it is clearly written at MSDN here the errors it gave where a bit unclear so hard to find and could not find it here at SO.

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

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

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

it seems that you should set your command as an String[],for example:

String[] command = new String[]{"rmiregistry","2020"};
Runtime.getRuntime().exec(command);

it just like the style of main(String[] args).

Type Services.msc in run panel of windows run window. It will list all the windows services in our system. Now we need to start Asp .net State service as show in the image.

Your issue will get resolved.

With HttpClient 4.5 you can do this:

CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(new PoolingHttpClientConnectionManager()).build();

Note that this one implements Closeable (for shutting down of the connection manager).

I've added the Initial Catalog to your connection string. I've also abandonded the ADODB.Command syntax in favor of simply creating my own SQL statement and open the recordset on that variable.

Hope this helps.

Sub GetDataFromADO()
    'Declare variables'
        Set objMyConn = New ADODB.Connection
        Set objMyRecordset = New ADODB.Recordset
        Dim strSQL As String

    'Open Connection'
        objMyConn.ConnectionString = "Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=MyDatabase;User ID=abc;Password=abc;"
        objMyConn.Open

    'Set and Excecute SQL Command'
        strSQL = "select * from myTable"

    'Open Recordset'
        Set objMyRecordset.ActiveConnection = objMyConn
        objMyRecordset.Open strSQL            

    'Copy Data to Excel'
        ActiveSheet.Range("A1").CopyFromRecordset (objMyRecordset)

End Sub

You need an Oracle Client: http://www.oracle.com/technology/oramag/oracle/08-nov/o68odpnet.html

I was also getting the same error and it simply got resolved after installing the MS offices driver and Execute the job in 32 Bit DTEXEC. Now it works fine.

You can get the setup from below.

For Oracle 11g (11.1.0.7.20) I had to add the following dlls along with my Exe to work.

1. oci.dll
2. OraOps11w.dll
3. oraociicus11.dll (pretty huge close to 30mb)
4. Oracle.DataAccess.dll

Check that there isn't a firewall that is ending the connection after certain period of time (this was the cause of a similar problem we had)

What does it mean?

That means that each iterator you obtain from a ConcurrentHashMap is designed to be used by a single thread and should not be passed around. This includes the syntactic sugar that the for-each loop provides.

What happens if I try to iterate the map with two threads at the same time?

It will work as expected if each of the threads uses it's own iterator.

What happens if I put or remove a value from the map while iterating it?

It is guaranteed that things will not break if you do this (that's part of what the "concurrent" in ConcurrentHashMap means). However, there is no guarantee that one thread will see the changes to the map that the other thread performs (without obtaining a new iterator from the map). The iterator is guaranteed to reflect the state of the map at the time of it's creation. Futher changes may be reflected in the iterator, but they do not have to be.

In conclusion, a statement like

for (Object o : someConcurrentHashMap.entrySet()) {
    // ...
}

will be fine (or at least safe) almost every time you see it.

The best solution is not to use the same element for column and panel:

<div class="row">
    <div class="col-md-3">
        <div class="panel" id="gameplay-away-team">Away Team</div>
    </div>
    <div class="col-md-6">
        <div class="panel" id="gameplay-baseball-field">Baseball Field</div>
    </div>
    <div class="col-md-3">
        <div class="panel" id="gameplay-home-team">Home Team</div>
    </div>
</div>

and some more styles:

#gameplay-baseball-field {
  padding-right: 10px;
  padding-left: 10px;
}

From the official documentation, does it not seem that the sample() method is appropriate for this purpose?

import random

def random_digits(n):
    num = range(0, 10)
    lst = random.sample(num, n)
    print str(lst).strip('[]')

Output:

>>>random_digits(5)
2, 5, 1, 0, 4

Try this:

for (var i in tracks[racer_id].data.points) {
    values = tracks[racer_id].data.points[i];                
    point = new google.maps.LatLng(values.lat, values.lng);
    if (values.qst) {
        var marker = new google.maps.Marker({map: map, position: point, clickable: true});
        tracks[racer_id].markers[i] = marker;
        var info = new google.maps.InfoWindow({
            content: '<b>Speed:</b> ' + values.inst + ' knots'
        });
        tracks[racer_id].info[i] = info;
        google.maps.event.addListener(tracks[racer_id].markers[i], 'click', function() {
            tracks[racer_id].info[i].open(map, tracks[racer_id].markers[i]);
        });
    }
    track_coordinates.push(point);
    bd.extend(point);
}

You'll have to pass the new ordinal position to insert using len in this case:

In [62]:

a=[1,2,3,4]
a.insert(len(a),5)
a
Out[62]:
[1, 2, 3, 4, 5]

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

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

There should be a line in your postgresql.conf file that says:

port = 1486

Change that.

The location of the file can vary depending on your install options. On Debian-based distros it is /etc/postgresql/8.3/main/

On Windows it is C:\Program Files\PostgreSQL\9.3\data

Don't forget to sudo service postgresql restart for changes to take effect.

With recent matplotlib versions you might want to try Constrained Layout. This does not work with plt.subplot() however, so you need to use plt.subplots() instead:

fig, axs = plt.subplots(4, 4, constrained_layout=True)

You can create a new empty array with your existing array size, and you can assign back them to your array. This may faster than other. Snipet:

package com.array.zero;
public class ArrayZero {
public static void main(String[] args) {
    // Your array with data
    int[] yourArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    //Creating same sized array with 0
    int[] tempArray = new int[yourArray.length];
    Assigning temp array to replace values by zero [0]
    yourArray = tempArray;

    //testing the array size and value to be zero
    for (int item : yourArray) {
        System.out.println(item);
    }
}
}

Result :

0
0
0
0
0    
0
0
0
0

Since value is the last entry, you can do:

metrics.sort_by(&:last)

My issue with the above solution is that it beark the string into formal size chunks regardless of the position in the sentences.

I think the following a better approach; although it needs some performance tweaking:

 static chunkString(str, length, size,delimiter='\n' ) {
        const result = [];
        for (let i = 0; i < str.length; i++) {
            const lastIndex = _.lastIndexOf(str, delimiter,size + i);
            result.push(str.substr(i, lastIndex - i));
            i = lastIndex;
        }
        return result;
    }

To create a .gitignore file, in terminal navigate to your apps directory and use the following command

touch .gitignore

Then you can open it up in a your text editor and put the above code into it.

Pretty Late answer though. But This has worked for me , and could be useful.

While Using Spring Security ans mockMvc, all you need to is use @WithMockUser annotation like others are mentioned.

Spring security also provides another annotation called @WithAnonymousUser for testing unauthenticated requests. However you should be careful here. You would be expecting 401, but I got 403 Forbidden Error by default. In actual scenarios, when you are running actual service, It is redirected and you end up getting the correct 401 response code.Use this annotation for anonymous requests.

You may also think of ommitting the annotaions and simply keep it unauthorized. But this usually raises the correct exceptions(like AuthenticationException), but you will get correct status code if it is handled correctly(If you are using custom handler). I used to get 500 for this. So look for the exceptions raised in the debugger, and check if it is handled rightly and returns the correct status code.

You can create an element with an id and then assign that length value to that element.

var name = prompt("What's your name?");_x000D_
var lengthOfName = name.length_x000D_
document.getElementById('message').innerHTML = lengthOfName;

<p id='message'></p>

Try using:

@Html.DisplayFor(model => model.userName) <br/>
@Html.HiddenFor(model => model.userName)

Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.

Here's an example:

<section class="content">            
    <div class="modal"></div>
</section>

<div class="side-tab"></div>

// CSS //
.content {
    position: relative;
    z-index: 1;
}

.modal {
    position: fixed;
    z-index: 100;
}

.side-tab {
    position: fixed;
    z-index: 5;
}

In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.

Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/

If your FK column table should contain that FK value as a primary key Value then data will be inserted.

For Apache 2.4.9

in addition, look at the httpd-vhosts.conf file in C:\wamp\bin\apache\apache2.4.9\conf\extra

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require local
</Directory>
</VirtualHost>

Change to:

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require all granted
</Directory>
</VirtualHost>

changing from "Require local" to "Require all granted" solved the error 403 in my local network

Another solution - you can use local variable:

<div th:with="expr_result = ${potentially_complex_expression}">
    <div th:if="${expr_result}">
        <h2>Hello!</h2>
    </div>
    <div th:unless="${expr_result}">
        <span class="xxx">Something else</span>
    </div>
</div>

You can use the following query for MYSQL:

SHOW `columns` FROM `your-table`;

Below is the example code which shows How to implement above syntax in php to list the names of columns:

$sql = "SHOW COLUMNS FROM your-table";
$result = mysqli_query($conn,$sql);
while($row = mysqli_fetch_array($result)){
    echo $row['Field']."<br>";
}

For Details about output of SHOW COLUMNS FROM TABLE visit: MySQL Refrence.

In operating systems like Ubuntu python comes preinstalled. So the default version is python 2.7 you can confirm the version by typing below command in your terminal

python -V

if you installed it but didn't set default version you will see

python 2.7

in terminal. I will tell you how to set the default python version in Ubuntu.

A simple safe way would be to use an alias. Place this into ~/.bashrc or ~/.bash_aliases file:

alias python=python3

After adding the above in the file, run the command below:

source ~/.bash_aliases or source ~/.bashrc

now check python version again using python -V

if python version 3.x.x one, then the error is in your syntax like using print with parenthesis. change it to

test = input("enter the test")
print(test)

try this,

$("document").ready(function(){

$("your id here").trigger("click");
});

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

Laravel makes it very easy to manage your database connections through app/config/database.php.

As you noted, it is looking for a database called 'database'. The reason being that this is the default name in the database configuration file.

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'database', <------ Default name for database
    'username'  => 'root',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

Change this to the name of the database that you would like to connect to like this:

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'my_awesome_data', <------ change name for database
    'username'  => 'root',            <------ remember credentials
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

Once you have this configured correctly you will easily be able to access your database!

Happy Coding!

I have found a way to do it without using external sites.

<img src="https://drive.google.com/uc?export=view&id=XXX">

https://gist.github.com/evansims/f23e2f49e3d4be793038

<a href="https://drive.google.com/uc?export=view&id=XXX">
    <img src="https://drive.google.com/uc?export=view&id=XXX"
    style="width: 500px; max-width: 100%; height: auto"
    title="Click for the larger version." />
</a>

You'll need to grab the ID of the image: Click on “Open in new window” and get the ID from the URL.

Use conditional comments in HTML, like this:

<!--[if IE 8]>
<style>...</style>
<![endif]-->

See here: http://www.quirksmode.org/css/condcom.html

You can test for IE versions reliably and also be sure other browsers won't be confused.

Doxygen or Sandcastle help file builder are the primary tools that will extract XML documentation into HTML (and other forms) of external documentation.

Note that you can combine these documentation exporters with documentation generators - as you've discovered, Resharper has some rudimentary helpers, but there are also much more advanced tools to do this specific task, such as GhostDoc (for C#/VB code with XML documentation) or my addin Atomineer Pro Documentation (for C#, C++/CLI, C++, C, VB, Java, JavaScript, TypeScript, JScript, PHP, Unrealscript code containing XML, Doxygen, JavaDoc or Qt documentation).

This works for SQL Server 2005 - 2012. Look for event id = 26022 in the error log under applications. That will show the port number of sql server as well as what ip addresses are allowed to access.

You should use something similar to this for adding TextView to LinearLayout dynamically:

LinearLayout linearLayout = getActivity().findViewById(R.id.infoLayout);

TextView valueTV = new TextView(context);
valueTV.setText("hallo hallo");
valueTV.setId(Integer.parseInt("5"));
valueTV.setLayoutParams(new LinearLayout.LayoutParams(
       LinearLayout.LayoutParams.FILL_PARENT,
       LinearLayout.LayoutParams.WRAP_CONTENT));

linearLayout.addView(valueTV);

getActivity() is used for inside Fragments, you can use context or anything similar per each instance you are inside.

Unfortunately in Entity Framework 5 DbContext the issue is still not fixed.

I used this workaround (works with MSSQL 2012 but ANSI NULLS setting might be deprecated in any future MSSQL version).

public class Context : DbContext
{

    public Context()
        : base("name=Context")
    {
        this.Database.Connection.StateChange += Connection_StateChange;
    }

    void Connection_StateChange(object sender, System.Data.StateChangeEventArgs e)
    {
        // Set ANSI_NULLS OFF when any connection is opened. This is needed because of a bug in Entity Framework
        // that is not fixed in EF 5 when using DbContext.
        if (e.CurrentState == System.Data.ConnectionState.Open)
        {
            var connection = (System.Data.Common.DbConnection)sender;
            using (var cmd = connection.CreateCommand())
            {
                cmd.CommandText = "SET ANSI_NULLS OFF";
                cmd.ExecuteNonQuery();
            }
        }
    }
}

It should be noted that it is a dirty workaround but it is one that can be implemented very quickly and works for all queries.

the_string = raw_input()
name, age = the_string.split()

Mirko Froehlich's answer worked for me, except when i wanted to use custom colors. The trick is to specify UI color with Hue, saturation and brightness instead of RGB.

CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = myView.bounds;
UIColor *startColour = [UIColor colorWithHue:.580555 saturation:0.31 brightness:0.90 alpha:1.0];
UIColor *endColour = [UIColor colorWithHue:.58333 saturation:0.50 brightness:0.62 alpha:1.0];
gradient.colors = [NSArray arrayWithObjects:(id)[startColour CGColor], (id)[endColour CGColor], nil];
[myView.layer insertSublayer:gradient atIndex:0];

To get the Hue, Saturation and Brightness of a color, use the in built xcode color picker and go to the HSB tab. Hue is measured in degrees in this view, so divide the value by 360 to get the value you will want to enter in code.

You need a second integer.

int i,n;
vector<int> V;
cout << "Enter the amount of numbers you want to evaluate: ";
cin >> i;
cout << "Enter your numbers to be evaluated: " << endl;
while (V.size() < i && cin >> n){
  V.push_back(n);
}
write_vector(V);
return 0;

I have solved this problem on my side by 2 ways:

1. Adding this configuration in pom.xml

   <configuration><argLine>-Xmx1024m</argLine></configuration>
   

2. Switch to used JDK 1.7 instead of 1.6

ProtocolBuffers is FASTER.
There is a nice benchmark here:

You might also want to look into Avro, as Avro is even faster.
Microsoft has a package here:

By the way, the fastest I've ever seen is Cap'nProto;
A C# implementation can be found at the Github-repository of Marc Gravell.

Use the pandas to_datetime function to parse the column as DateTime. Also, by using infer_datetime_format=True, it will automatically detect the format and convert the mentioned column to DateTime.

import pandas as pd
raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], infer_datetime_format=True)

I have faced same problem, and here is, how i solved the problem. Hope this will be helpful for someone.

// Swift 2

   lblMultiline.lineBreakMode = .ByWordWrapping // or use NSLineBreakMode.ByWordWrapping
   lblMultiline.numberOfLines = 0 

// Objective-C

  lblMultiline.lineBreakMode = NSLineBreakByWordWrapping;
  lblMultiline.numberOfLines = 0;

// C# (Xamarin.iOS)

  lblMultiline.LineBreakMode = UILineBreakMode.WordWrap;
  lblMultiline.Lines = 0;  

Here's one way in XSLT 2

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;','''')"/>   </xsl:template> </xsl:stylesheet> 

Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   <xsl:template match="@*|node()">     <xsl:copy>       <xsl:apply-templates select="@*|node()"/>     </xsl:copy>   </xsl:template>   <xsl:variable name="apos">'</xsl:variable>   <xsl:template match="text()">     <xsl:value-of select="translate(.,'&quot;',$apos)"/>   </xsl:template> </xsl:stylesheet> 

The application needs to be placed in the same directory as the scanned package:

I see Federico you've found solution by yourself. The problem was in two places. Assignations need proper quoting, in your case

SOME_PATH="/$COMPANY/someProject/some path"

is one of possible solutions.

But in shell those quotes are not stored in a memory, so when you want to use this variable, you need to quote it again, for example:

NEW_VAR="$SOME_PATH"

because if not, space will be expanded to command level, like this:

NEW_VAR=/YourCompany/someProject/some path

which is not what you want.

_{For more info you can check out my article about it http://www.cofoh.com/white-shell}

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

I believe you could addClass to the element. But either way you'd have to use Jquery or reg JS

div {
  opacity:0;
  transition:opacity 1s linear;*
}
div.SomeClass {
  opacity:1;
}

Offline maps are available on new version of Google map.

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

1. Standard Windows performance counters (look for other correlated activity, such as many GET requests, excessive network or disk I/O, etc); you can read them from code as well as from perfmon (to trigger data collection if CPU use exceeds a threshold, for example)
2. Custom performance counters (particularly to time for off-box requests and other calls where execution time is uncertain)
3. Load testing, using tools such as Visual Studio Team Test or WCAT
4. If you can test on or upgrade to IIS 7, you can configure Failed Request Tracing to generate a trace if requests take more a certain amount of time
5. Use logparser to see which requests arrived at the time of the CPU spike
6. Code reviews / walk-throughs (in particular, look for loops that may not terminate properly, such as if an error happens, as well as locks and potential threading issues, such as the use of statics)
7. CPU and memory profiling (can be difficult on a production system)
8. Process Explorer
9. Windows Resource Monitor
10. Detailed error logging
11. Custom trace logging, including execution time details (perhaps conditional, based on the CPU-use perf counter)
12. Are the errors happening when the AppPool recycles? If so, it could be a clue.

Dialect property is used by hibernate in following ways

1. To generate Optimized SQL queries.
2. If you have more than one DB then to talk with particular DB you want.
3. To set default values for hibernate configuration file properties based on the DB software we use even though they are not specifed in configuration file.

The ternary operator is a syntactic and readability convenience, not a performance shortcut. People are split on the merits of it for conditionals of varying complexity, but for short conditions, it can be useful to have a one-line expression.

Moreover, since it's an expression, as Charlie Martin wrote, that means it can appear on the right-hand side of a statement in C. This is valuable for being concise.

This one liner gives you the IP address:

(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString

Include it in a Variable?

$IPV4=(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString

Raminson has a nice answer if you are already (or don't mind) using jQuery Mobile. If you want a different solution, why not just modify your code as follows:

change that LI you're having trouble with to include an A tag and apply the class there instead of the LI

<!-- This is the main menu -->
<ul class="menu">
   <li><a href="/home/">HOME</a></li>
   <li><a href="#" class="publications">PUBLICATIONS &amp; PROJECTS</a></li>
   <li><a href="/about/">ABOUT</a></li>
   <li><a href="/blog/">BLOG</a></li>
   <li><a href="/contact/">CONTACT</a></li>
 </ul>

And your javascript/jquery code... return false to stop bubbling.

$(document).ready(function(){
   $('.publications').click(function() {
       $('#filter_wrapper').show();
       return false;
   });
 });

This should work for what you are trying to do.

Also, I noticed your site opens the other links in new tabs/windows, is that intentional?

This 
 should work if you just use a simple title attribute.

on bootstrap popovers, just use data-html="true" and use html in the data-content attribute .

<div title="Hello &#013;World">hover here</div>

Also you can try zenity !

user=$(zenity --entry --text 'Please enter the username:') || exit 1

edit Outdated, just use git push -u origin $BRANCHNAME

Use git publish-branch from William's miscellaneous Git tools.

OK, no Ruby, so - ignoring the safeguards! - take the last three lines of the script and create a bash script, git-publish-branch:

#!/bin/bash
REMOTE=$1 # Rewrite this to make it optional...
BRANCH=$2
# Uncomment the following line to create BRANCH locally first
#git checkout -b ${BRANCH}
git push ${ORIGIN} ${BRANCH}:refs/heads/${BRANCH} &&
git config branch.${BRANCH}.remote ${REMOTE} &&
git config branch.${BRANCH}.merge refs/heads/${BRANCH}

Then run git-publish-branch REMOTENAME BRANCHNAME, where REMOTENAME is usually origin (you may modify the script to take origin as default, etc...)

The size attribute works, as well

<input size="25" type="text">

You can install cygwin, which has rm as well as ls etc.

You can first get all the view controllers in the array and then after checking with the corresponding view controller class, you can delete the one you want.

Here is small piece of code:

NSArray* tempVCA = [self.navigationController viewControllers];

for(UIViewController *tempVC in tempVCA)
{
    if([tempVC isKindOfClass:[urViewControllerClass class]])
    {
        [tempVC removeFromParentViewController];
    }
}

I think this will make your work easier.

I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

In my case, none of above answers nor google's official documentation helped me to grab the concept of PendingIntent class.

And then I found this video, Google I/O 2013, Beyond the Blue Dot session. In this video, ex-googler Jaikumar Ganesh explains what PendingIntent is, and that was the thing gave me the big picture of this.

Below is just transcription of above video (from 15:24).

So what's a pending intent?

It's a token that your app process will give to the location process, and the location process will use it to wake up your app when an event of interest happens. So this basically means that your app in the background doesn't have to be always running. When something of interest happens, we will wake you up. This saves a lot of battery.

This explanation becomes more clear with this snippet of code(which is included in the session's slide).

PendingIntent mIntent = PendingIntent.getService(...);

mLocationClient.requestLocationUpdates(locationRequest, mIntent);

public void onHandleIntent(Intent intent) {   
    String action = intent.getAction();   
    if (ACTION_LOCATION.equals(action)) {       
        Location location = intent.getParcelableExtra(...)   
    }
}

Is this what you are looking for? Here is a fiddle demo.

The layout is based on percentage, colors are for clarity. If the content column overflows, a scrollbar should appear.

body, html, .container-fluid {
  height: 100%;
}

.navbar {
  width:100%;
  background:yellow;
}

.article-tree {
  height:100%;
  width: 25%;
  float:left;
  background: pink;
}

.content-area {
  overflow: auto;
  height: 100%;
  background:orange;
}

.footer {
   background: red;
   width:100%;
   height: 20px;
}

if (variable) can be used if variable is guaranteed to be an object, or if false, 0, etc. are considered "default" values (hence equivalent to undefined or null).

typeof variable == 'undefined' can be used in cases where a specified null has a distinct meaning to an uninitialised variable or property. This check will not throw and error is variable is not declared.

Windows 7 location is: C:\Users\All Users\MySQL\MySQL Server 5.5\my.ini

For XP may be: C:\Documents and Settings\All Users\MySQL\MySQL Server 5.5\my.ini

At the tops of these files are comments defining where my.cnf can be found.

If you are having this issue and can't find the MySQL service either, just launch "MySQL Installer" from the Start menu (or download it), then choose "Reconfigure" on MySQL Server. Follow the steps to set a root user password and then the service will be created and started automatically (and set to auto-start on boot).

I had this problem. I solved it with downloading 64x of the Java. Here is the link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=87443

Put into a script I like something like that:

#!/bin/bash
set -o xtrace # remove me after debug
TABLE=some_table_name
DB_NAME=prod_database

BASE_DIR=/var/backups/someDir
LOCATION="${BASE_DIR}/myApp_$(date +%Y%m%d_%H%M%S)"
FNAME="${LOCATION}_${DB_NAME}_${TABLE}.sql"

# Create backups directory if not exists
if [[ ! -e $BASE_DIR ]];then
       mkdir $BASE_DIR
       chown -R postgres:postgres $BASE_DIR
fi

sudo -H -u postgres pg_dump --column-inserts --data-only --table=$TABLE $DB_NAME > $FNAME
sudo gzip $FNAME

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

Solution 1

Use the powershell pipeline to get packages and remove in single statement like this

Get-Package | Uninstall-Package

Solution 2

if you want to uninstall selected packages follow these steps

1. Use GetPackages to get the list of packages
2. Download Nimble text software
3. Copy the output of GetPackages in NimbleText(For each row in the list window)
4. Set Column Seperator to ( if required
5. Type Uninstall-Package $0 (Substitute using pattern window)
6. Copy the results and paste them in Package Manage Console

That be all folks.

This works for me:

int[] list = new int[maximum];
for (int i = 0; i < maximum; i++{
    list[i] = put_input_here;
}

This way, it's simple, yet efficient.

Using file extension and getimagesize function to detect if uploaded file has right format is just the entry level check and it can simply bypass by uploading a file with true extension and some byte of an image header but wrong content.

for being secure and safe you may make thumbnail/resize (even with original image sizes) the uploaded picture and save this version instead the uploaded one. Also its possible to get uploaded file content and search it for special character like <?php to find the file is image or not.

First, using a page-file when you have 4 GB of RAM is useless. Windows can't access more than 4GB (actually, less because of memory holes) so the page file is not used.

Second, the address space is split in 2, half for kernel, half for user mode. If you need more RAM for your applications use the /3GB option in boot.ini (make sure java.exe is marked as "large address aware" (google for more info).

Third, I think you can't allocate the full 2 GB of address space because java wastes some memory internally (for threads, JIT compiler, VM initialization, etc). Use the /3GB switch for more.

You can use the PerformanceCounter class from System.Diagnostics.

Initialize like this:

PerformanceCounter cpuCounter;
PerformanceCounter ramCounter;

cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");
ramCounter = new PerformanceCounter("Memory", "Available MBytes");

Consume like this:

public string getCurrentCpuUsage(){
            return cpuCounter.NextValue()+"%";
}

public string getAvailableRAM(){
            return ramCounter.NextValue()+"MB";
} 

This error will occur if the configuration file of the hosting application of your WCF service does not have the proper configuration.

Remember this comment from configuration:

When deploying the service library project, the content of the config file must be added to the host's app.config file. System.Configuration does not support config files for libraries.

If you have a WCF Service hosted in IIS, during runtime via VS.NET it will read the app.config of the service library project, but read the host's web.config once deployed. If web.config does not have the identical <system.serviceModel> configuration you will receive this error. Make sure to copy over the configuration from app.config once it has been perfected.

If you want using it with parameter (ie. delete all subdirs under the given directory), then put this two lines into a *.bat or *.cmd file:

@echo off
for /f "delims=" %%d in ('dir %1 /s /b /ad ^| sort /r') do rd "%%d" 2>nul && echo rmdir %%d

and add script-path to your PATH environment variable. In this case you can call your batch file from any location (I suppose UNC path should work, too).

Eg.:

YourBatchFileName c:\temp

(you may use quotation marks if needed)

will remove all empty subdirs under c:\temp folder

YourBatchFileName

will remove all empty subdirs under the current directory.

Another way of inserting the tab literally inside the expression is using the lesser-known $'\t' quotation in Bash:

grep $'foo\tbar'        # matches eg. 'foo<tab>bar'

(Note that if you're matching for fixed strings you can use this with '-F' mode.)

Sometimes using variables can make the notation a bit more readable and manageable:

tab=$'\t'               # `tab=$(printf '\t')` in POSIX
id='[[:digit:]]\+'
name='[[:alpha:]_][[:alnum:]_-]*'
grep "$name$tab$id"     # matches eg. `bob2<tab>323`

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

check the name of the database in a file where you established a connection.

I faced the same issue. String.Replace('\\.','') is not valid statement and throws the same error. Thanks to C# we can use double quotes instead of single quotes and following works String.Replace("\\.","")

You can use Floern's solution. You may also want to disable the input while you set the color to gray. http://www.w3schools.com/tags/att_input_disabled.asp

This case is valid for Debian.

Add the following to /etc/rc.local

/usr/bin/sudo -u {{user}} /usr/local/bin/forever start {{app path}}

• {{user}} replaces your username.
• {{app path}} replaces your app path. For example, /var/www/test/app.js

A stateful app is one that stores information about what has happened or changed since it started running. Any public info about what "mode" it is in, or how many records is has processed, or whatever, makes it stateful.

Stateless apps don't expose any of that information. They give the same response to the same request, function or method call, every time. HTTP is stateless in its raw form - if you do a GET to a particular URL, you get (theoretically) the same response every time. The exception of course is when we start adding statefulness on top, e.g. with ASP.NET web apps :) But if you think of a static website with only HTML files and images, you'll know what I mean.

1.Get supplier numbers and names for suppliers of parts supplied to at least two different projects.

I am not slear about your second question

If you are using windows, just search for miniconda and you'll find the folder. Go into the folder and you'll find a miniconda uninstall exe file. Run it.

I was facing the same problem while using Windows 10. I have solved the problem using the following procedure

1. Download Java from https://java.com/en/download/windows-64bit.jsp for 64-bit windows\Install it
2. Download Java development kit from https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html for 64-bit windows\Install it
3. Then right click on “This PC” icon in desktop\Properties\Advanced system settings\Advanced\Environment Variables\Under System variables select Path\Click Edit\Click on New\Copy and paste paths “C:\Program Files\Java\jdk1.8.0_201\bin” and “C:\Program Files\Java\jre1.8.0_201\bin” (without quote) \OK\OK\OK

Note: jdk1.8.0_201 and jre1.8.0_201 will be changed depending on the version of Java development kit and Java

4. In Environment Variables window go to User variables for User\Click on New\Put Variable name as “JAVA_HOME” and Variable value as “C:\Program Files\Java\jdk1.8.0_201\bin”\Press OK

To check the installation, open CMD\Type javac\Press Enter and Type java\press enter It will show

In RStudio run

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jdk1.8.0_201")

Note: jdk1.8.0_201 will be changed depending on the version of Java development kit

Now you can install and load rJava package without any problem.

The default behaviour is false:

By default, ApplicationContext implementations eagerly create and configure all singleton beans as part of the initialization process. Generally, this pre-instantiation is desirable, because errors in the configuration or surrounding environment are discovered immediately, as opposed to hours or even days later. When this behavior is not desirable, you can prevent pre-instantiation of a singleton bean by marking the bean definition as lazy-initialized. A lazy-initialized bean tells the IoC container to create a bean instance when it is first requested, rather than at startup.

I suggest reading up

var myVar = null;

if(myVar)
   clearTimeout(myVar);

myVar = setTimeout(function(){ alert("Hello"); }, 3000);

If you want to iterate over every item in the array as if it were a flattened array, you can just do:

foreach (int i in array) {
    Console.Write(i);
}

which would print

123456

If you want to be able to know the x and y indexes as well, you'll need to do:

for (int x = 0; x < array.GetLength(0); x += 1) {
    for (int y = 0; y < array.GetLength(1); y += 1) {
        Console.Write(array[x, y]);
    }
}

Alternatively you could use a jagged array instead (an array of arrays):

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
foreach (int[] subArray in array) {
    foreach (int i in subArray) {
        Console.Write(i);
    }
}

or

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
for (int j = 0; j < array.Length; j += 1) {
    for (int k = 0; k < array[j].Length; k += 1) {
        Console.Write(array[j][k]);
    }
}

I'm running Push Notifications (with background fetching). When my app is in the background and I receive a push notification, I found that didReceiveRemoteNotification in appDelegate would be called twice; once for when notification is received and another when user clicks on the notification alert.

To detect if notification alert was clicked, just check if applicationState raw value == 1 inside didReceiveRemoteNotification in appDelegate.

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject: AnyObject]) {
    // If not from alert click applicationState(1)
    if (application.applicationState.rawValue != 1) {
        // Run your code here
    }
}

I hope this helps.

There is tool named unpushed that scans all Git, Mercurial and Subversion repos in specified working directory and shows list of ucommited files and unpushed commits. Installation is simple under Linux:

$ easy_install --user unpushed

or

$ sudo easy_install unpushed

to install system-wide.

Usage is simple too:

$ unpushed ~/workspace
* /home/nailgun/workspace/unpushed uncommitted (Git)
* /home/nailgun/workspace/unpushed:master unpushed (Git)
* /home/nailgun/workspace/python:new-syntax unpushed (Git)

See unpushed --help or official description for more information. It also has a cronjob script unpushed-notify for on-screen notification of uncommited and unpushed changes.

I have tested a full layout using flexbox it contains header, footer, main body with left, center and right panels and the panels can contain menu items or footer and headers that should scroll. Pretty complex

IE11 and even IE EDGE have some problems displaying the flex content but it can be overcome. I have tested it in most browsers and it seems to work.

Some fixed i have applies are IE11 height bug, Adding height:100vh and min-height:100% to the html/body. this also helps to not have to set height on container in the dom. Also make the body/html a flex container. Otherwise IE11 will compress the view.

html,body {
    display: flex;
    flex-flow:column nowrap;
    height:100vh; /* fix IE11 */
    min-height:100%; /* fix IE11 */  
}

A fix for IE EDGE that overflows the flex container: overflow:hidden on main flex container. if you remove the overflow, IE EDGE wil push the content out of the viewport instead of containing it inside the flex main container.

main{
    flex:1 1 auto;
    overflow:hidden; /* IE EDGE overflow fix */  
}

You can see my testing and example on my codepen page. I remarked the important css parts with the fixes i have applied and hope someone finds it useful.

I found another workaround that is very simple: 1. Cut the contents 2. Paste them in the new location 3. Copy the contents that you just pasted into the new location you want. 4. Undo the Cut-Paste operation, putting the original contents back where you got them. 5. Paste the contents from the clipboard to the same location. These contents will have the original references.

It looks like a lot, but is super fast with keyboard shortcuts: 1. Ctrl-x, 2. Ctrl-v, 3. Ctrl-c, 4. Ctrl-z, 5. Ctrl-v

It's been correctly pointed out above that finding a given word in a sentence is not the same as finding the charsequence, and can be done as follows if you don't want to mess around with regular expressions.

boolean checkWordExistence(String word, String sentence) {
    if (sentence.contains(word)) {
        int start = sentence.indexOf(word);
        int end = start + word.length();

        boolean valid_left = ((start == 0) || (sentence.charAt(start - 1) == ' '));
        boolean valid_right = ((end == sentence.length()) || (sentence.charAt(end) == ' '));

        return valid_left && valid_right;
    }
    return false;
}

Output:

checkWordExistence("the", "the earth is our planet"); true
checkWordExistence("ear", "the earth is our planet"); false
checkWordExistence("earth", "the earth is our planet"); true

P.S Make sure you have filtered out any commas or full stops beforehand.

Switch Target framework to 4.5.2 or something higher and bring it back to your original version (example: 4.5) then when you build, it will work.

Existing solutions did not work for me (details below). What finally worked was to implement readline using read(1) (based on this answer). The latter does not block:

from subprocess import Popen, PIPE
from threading import Thread
def process_output(myprocess): #output-consuming thread
    nextline = None
    buf = ''
    while True:
        #--- extract line using read(1)
        out = myprocess.stdout.read(1)
        if out == '' and myprocess.poll() != None: break
        if out != '':
            buf += out
            if out == '\n':
                nextline = buf
                buf = ''
        if not nextline: continue
        line = nextline
        nextline = None

        #--- do whatever you want with line here
        print 'Line is:', line
    myprocess.stdout.close()

myprocess = Popen('myprogram.exe', stdout=PIPE) #output-producing process
p1 = Thread(target=process_output, args=(dcmpid,)) #output-consuming thread
p1.daemon = True
p1.start()

#--- do whatever here and then kill process and thread if needed
if myprocess.poll() == None: #kill process; will automatically stop thread
    myprocess.kill()
    myprocess.wait()
if p1 and p1.is_alive(): #wait for thread to finish
    p1.join()

Why existing solutions did not work:

1. Solutions that require readline (including the Queue based ones) always block. It is difficult (impossible?) to kill the thread that executes readline. It only gets killed when the process that created it finishes, but not when the output-producing process is killed.
2. Mixing low-level fcntl with high-level readline calls may not work properly as anonnn has pointed out.
3. Using select.poll() is neat, but doesn't work on Windows according to python docs.
4. Using third-party libraries seems overkill for this task and adds additional dependencies.

C++ (and C for that matter) split the "declaration" and the "implementation" of types, functions and classes. You should "declare" the classes you need in a header-file (.h or .hpp), and put the corresponding implementation in a .cpp-file. Then, when you wish to use (access) a class somewhere, you #include the corresponding headerfile.

Example

ClassOne.hpp:

class ClassOne
{
public:
  ClassOne(); // note, no function body        
  int method(); // no body here either
private:
  int member;
};

ClassOne.cpp:

#include "ClassOne.hpp"

// implementation of constructor
ClassOne::ClassOne()
 :member(0)
{}

// implementation of "method"
int ClassOne::method()
{
  return member++;
}

main.cpp:

#include "ClassOne.hpp" // Bring the ClassOne declaration into "view" of the compiler

int main(int argc, char* argv[])
{
  ClassOne c1;
  c1.method();

  return 0;
}

Do you even need MSDTC? The escalation you're experiencing is often caused by creating multiple connections within a single TransactionScope.

If you do need it then you need to enable it as outlined in the error message. On XP:

• Go to Administrative Tools -> Component Services
• Expand Component Services -> Computers ->
• Right-click -> Properties -> MSDTC tab
• Hit the Security Configuration button

In my case, the IIS application pool was not set to v4. It was v2.

Changed the AppPool to v4 and everything was okay.

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

Follow the 3 step approach for a one or a few number of tags.

Step 1: Identify the commit/object ID of the commit the current tag is pointing to

command: git rev-parse <tag name>
example: git rev-parse v0.1.0-Demo
example output: db57b63b77a6bae3e725cbb9025d65fa1eabcde

Step 2: Delete the tag from the repository

command: git tag -d <tag name>
example: git tag -d v0.1.0-Demo
example output: Deleted tag 'v0.1.0-Demo' (was abcde)

Step 3: Create a new tag pointing to the same commit id as the old tag was pointing to

command: git tag -a <tag name>  -m "appropriate message" <commit id>
example: git tag -a v0.1.0-full  -m "renamed from v0.1.0-Demo" db57b63b77a6bae3e725cbb9025d65fa1eabcde
example output: Nothing or basically <No error>

Once the local git is ready with the tag name change, these changes can be pushed back to the origin for others to take these:

command: git push origin :<old tag name> <new tag name>
example: git push origin :v0.1.0-Demo v0.1.0-full
example output: <deleted & new tags>

I find it easiest to understand move semantics with example code. Let's start with a very simple string class which only holds a pointer to a heap-allocated block of memory:

#include <cstring>
#include <algorithm>

class string
{
    char* data;

public:

    string(const char* p)
    {
        size_t size = std::strlen(p) + 1;
        data = new char[size];
        std::memcpy(data, p, size);
    }

Since we chose to manage the memory ourselves, we need to follow the rule of three. I am going to defer writing the assignment operator and only implement the destructor and the copy constructor for now:

    ~string()
    {
        delete[] data;
    }

    string(const string& that)
    {
        size_t size = std::strlen(that.data) + 1;
        data = new char[size];
        std::memcpy(data, that.data, size);
    }

The copy constructor defines what it means to copy string objects. The parameter const string& that binds to all expressions of type string which allows you to make copies in the following examples:

string a(x);                                    // Line 1
string b(x + y);                                // Line 2
string c(some_function_returning_a_string());   // Line 3

Now comes the key insight into move semantics. Note that only in the first line where we copy x is this deep copy really necessary, because we might want to inspect x later and would be very surprised if x had changed somehow. Did you notice how I just said x three times (four times if you include this sentence) and meant the exact same object every time? We call expressions such as x "lvalues".

The arguments in lines 2 and 3 are not lvalues, but rvalues, because the underlying string objects have no names, so the client has no way to inspect them again at a later point in time. rvalues denote temporary objects which are destroyed at the next semicolon (to be more precise: at the end of the full-expression that lexically contains the rvalue). This is important because during the initialization of b and c, we could do whatever we wanted with the source string, and the client couldn't tell a difference!

C++0x introduces a new mechanism called "rvalue reference" which, among other things, allows us to detect rvalue arguments via function overloading. All we have to do is write a constructor with an rvalue reference parameter. Inside that constructor we can do anything we want with the source, as long as we leave it in some valid state:

    string(string&& that)   // string&& is an rvalue reference to a string
    {
        data = that.data;
        that.data = nullptr;
    }

What have we done here? Instead of deeply copying the heap data, we have just copied the pointer and then set the original pointer to null (to prevent 'delete[]' from source object's destructor from releasing our 'just stolen data'). In effect, we have "stolen" the data that originally belonged to the source string. Again, the key insight is that under no circumstance could the client detect that the source had been modified. Since we don't really do a copy here, we call this constructor a "move constructor". Its job is to move resources from one object to another instead of copying them.

Congratulations, you now understand the basics of move semantics! Let's continue by implementing the assignment operator. If you're unfamiliar with the copy and swap idiom, learn it and come back, because it's an awesome C++ idiom related to exception safety.

    string& operator=(string that)
    {
        std::swap(data, that.data);
        return *this;
    }
};

Huh, that's it? "Where's the rvalue reference?" you might ask. "We don't need it here!" is my answer :)

Note that we pass the parameter that by value, so that has to be initialized just like any other string object. Exactly how is that going to be initialized? In the olden days of C++98, the answer would have been "by the copy constructor". In C++0x, the compiler chooses between the copy constructor and the move constructor based on whether the argument to the assignment operator is an lvalue or an rvalue.

So if you say a = b, the copy constructor will initialize that (because the expression b is an lvalue), and the assignment operator swaps the contents with a freshly created, deep copy. That is the very definition of the copy and swap idiom -- make a copy, swap the contents with the copy, and then get rid of the copy by leaving the scope. Nothing new here.

But if you say a = x + y, the move constructor will initialize that (because the expression x + y is an rvalue), so there is no deep copy involved, only an efficient move. that is still an independent object from the argument, but its construction was trivial, since the heap data didn't have to be copied, just moved. It wasn't necessary to copy it because x + y is an rvalue, and again, it is okay to move from string objects denoted by rvalues.

To summarize, the copy constructor makes a deep copy, because the source must remain untouched. The move constructor, on the other hand, can just copy the pointer and then set the pointer in the source to null. It is okay to "nullify" the source object in this manner, because the client has no way of inspecting the object again.

I hope this example got the main point across. There is a lot more to rvalue references and move semantics which I intentionally left out to keep it simple. If you want more details please see my supplementary answer.

It is easy to change the implementation to List to Set:

Collection<String> stringList = new ArrayList<String>();
//Client side
stringList = new LinkedList<String>();

stringList = new HashSet<String>();
//stringList = new HashSet<>(); java 1.7 and 1.8

If it´s in the global scope it´s better to use:

function foo()
{
    alert('foo');
}

var a = 'foo';
window[a]();

than eval(). Because eval() is evaaaaaal.

Exactly like Nosredna said 40 seconds before me that is >.<

As a good practice I think it is a good idea to test if a popup was blocked and take action in case. You need to know that window.open has a return value, and that value may be null if the action failed. For example, in the following code:

function pop(url,w,h) {
    n=window.open(url,'_blank','toolbar=0,location=0,directories=0,status=1,menubar=0,titlebar=0,scrollbars=1,resizable=1,width='+w+',height='+h);
    if(n==null) {
        return true;
    }
    return false;
}

if the popup is blocked, window.open will return null. So the function will return false.

As an example, imagine calling this function directly from any link with target="_blank": if the popup is successfully opened, returning false will block the link action, else if the popup is blocked, returning true will let the default behavior (open new _blank window) and go on.

<a href="http://whatever.com" target="_blank" onclick='return pop("http://whatever.com",300,200);' >

This way you will have a popup if it works, and a _blank window if not.

If the popup does not open, you can:

• open a blank window like in the example and go on
• open a fake popup (an iframe inside the page)
• inform the user ("please allow popups for this site")
• open a blank window and then inform the user etc..

For two char sequence as delimeters "AND" and "OR" this should be worked. Don't forget to trim while using.

 String text ="ISTANBUL AND NEW YORK AND PARIS OR TOKYO AND MOSCOW";
 String[] cities = text.split("AND|OR"); 

Result : cities = {"ISTANBUL ", " NEW YORK ", " PARIS ", " TOKYO ", " MOSCOW"}

cat ip_address.txt | grep '^[0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}[,].*$\|^.*[,][0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}[,].*$\|^.*[,][0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}[.][0-9]\{1,3\}$'

Lets assume the file is comma delimited and the position of ip address in the beginning ,end and somewhere in the middle

First regexp looks for the exact match of ip address in the beginning of the line. The second regexp after the or looks for ip address in the middle.we are matching it in such a way that the number that follows ,should be exactly 1 to 3 digits .falsy ips like 12345.12.34.1 can be excluded in this.

The third regexp looks for the ip address at the end of the line

1. You take scanf().
2. You throw it in the bin.
3. You use fgets() to get an entire line.
4. You use strtol() to parse the line as an integer, checking if it consumed the entire line.

char *end;
char buf[LINE_MAX];

do {
     if (!fgets(buf, sizeof buf, stdin))
        break;

     // remove \n
     buf[strlen(buf) - 1] = 0;

     int n = strtol(buf, &end, 10);
} while (end != buf + strlen(buf));

One possible cause is that the second assembly is installed in GAC while the first assembly, with a higher version number, is added to the References of the project. To verify this, double click the assembly in the project references, and check if there is another assembly with the same name in the Object Browser.

If that is the case, use the gacutil.exe utility to uninstall the second assembly from the GAC. For example, if these are 64-bit assemblies:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\x64\gacutil.exe -u <assembly_name>

DIVs inherently lack any useful meaning, other than to divide, of course.

Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.

<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>

h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}

With C# 3.0 you can create an extension method as follows:

public static class ExtensionMethods
{
    // Deep clone
    public static T DeepClone<T>(this T a)
    {
        using (MemoryStream stream = new MemoryStream())
        {
            BinaryFormatter formatter = new BinaryFormatter();
            formatter.Serialize(stream, a);
            stream.Position = 0;
            return (T) formatter.Deserialize(stream);
        }
    }
}

which extends any class that's been marked as [Serializable] with a DeepClone method

MyClass copy = obj.DeepClone();

I'm super late to the party, but this doesn't appear in any of the existing answers:

GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', date_column) / 10 * 10, '2000')

• The 10 and MINUTE terms can be changed to any number and DATEPART, respectively.
• It is a DATETIME value, which means:
  • It works fine across long time intervals. (There is no collision between years.)
  • Including it in the SELECT statement will give your output a column with pretty output truncated at the level you specify.
• '2000' is an "anchor date" around which SQL will perform the date math. Jereonh discovered below that you encounter an integer overflow with the previous anchor (0) when you group recent dates by seconds or milliseconds.^†

SELECT   DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
                                                               AS [date_truncated],
         COUNT(*) AS [records_in_interval],
         AVG(aa.[value]) AS [average_value]
FROM     [friib].[dbo].[archive_analog] AS aa
GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, '2000', aa.[date]) / 10 * 10, '2000')
ORDER BY [date_truncated]

If your data spans centuries,^‡ using a single anchor date for second- or millisecond grouping will still encounter the overflow. If that is happening, you can ask each row to anchor the binning comparison to its own date's midnight:

• Use DATEADD(DAY, DATEDIFF(DAY, 0, aa.[date]), 0) instead of '2000' wherever it appears above. Your query will be totally unreadable, but it will work.

• An alternative might be CONVERT(DATETIME, CONVERT(DATE, aa.[date])) as the replacement.

_{^† 2³² ˜ 4.29E+9, so if your DATEPART is SECOND, you get 4.3 billion seconds on either side, or "anchor ± 136 years." Similarly, 2³² milliseconds is ˜ 49.7 days.
^‡ If your data actually spans centuries or millenia and is still accurate to the second or millisecond… congratulations! Whatever you're doing, keep doing it.}

I would think , in a large file scenario using a stream would be far more efficient, because memory consumption would be very small.

But your algorithm could alternate between using a stream and loading the entire thing in memory based on the file size. I wouldn't be surprised if one is only better than the other under certain criteria.

Your memcpy code is correct.

My guess is you are lacking an include of string.h. So the compiler assumes a wrong prototype of memcpy and thus the warning.

Anyway, you should just assign the structs for the sake of simplicity (as Joachim Pileborg pointed out).

    [HttpGet]
    public ActionResult<YOUROBJECT> Get()
    {
        return StatusCode(304);
    }

Optionally you can return an object with the response

    [HttpGet]
    public ActionResult<YOUROBJECT> Get()
    {
        return StatusCode(304, YOUROBJECT); 
    }

If you're using the compatibility ActionBar from the recent v7 appcompat support package, you can get the height using

OpenSSL is quite difficult. It's easy to accidentally throw away all your security by not doing negotiation exactly right. (Heck, I've been personally bitten by a bug where curl wasn't reading the OpenSSL alerts exactly right, and couldn't talk to some sites.)

If you really want quick and simple, put stud in front of your program an call it a day. Having SSL in a different process won't slow you down: http://vincent.bernat.im/en/blog/2011-ssl-benchmark.html

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

With Java 8 you can do also something like this with every normal methods:

Object returnValue = TimeIt.printTime(() -> methodeWithReturnValue());
//do stuff with your returnValue

with TimeIt like:

public class TimeIt {

public static <T> T printTime(Callable<T> task) {
    T call = null;
    try {
        long startTime = System.currentTimeMillis();
        call = task.call();
        System.out.print((System.currentTimeMillis() - startTime) / 1000d + "s");
    } catch (Exception e) {
        //...
    }
    return call;
}
}

With this methode you can make easy time measurement anywhere in your code without breaking it. In this simple example i just print the time. May you add a Switch for TimeIt, e.g. to only print the time in DebugMode or something.

If you are working with Function you can do somthing like this:

Function<Integer, Integer> yourFunction= (n) -> {
        return IntStream.range(0, n).reduce(0, (a, b) -> a + b);
    };

Integer returnValue = TimeIt.printTime2(yourFunction).apply(10000);
//do stuff with your returnValue

public static <T, R> Function<T, R> printTime2(Function<T, R> task) {
    return (t) -> {
        long startTime = System.currentTimeMillis();
        R apply = task.apply(t);
        System.out.print((System.currentTimeMillis() - startTime) / 1000d
                + "s");
        return apply;
    };
}

How about this for a clear

- os.system('cls')

That is about as short as could be!

Just in case I trip over this error in 2 weeks again... My case: Checkout an existing project via git and pull in all dependencies via composer. Came down to the same error listed within the title of this post.

Solution:

composer dump-autoload
composer install --no-scripts

make sure everything works now as expected (no errors!)

composer update

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

Use this to get the page scroll position.

var screenTop = $(document).scrollTop();

$('#content').css('top', screenTop);

Double Click the Login Button in the NETBEANS or add the Event Listener on Click Event (ActionListener)

btnLogin.addActionListener(new ActionListener() 
{
    public void actionPerformed(ActionEvent e) {
        this.setVisible(false);
        new FrmMain().setVisible(true); // Main Form to show after the Login Form..
    }
});

<script type="text/javascript">var s = '/Controller/Action#11112';if(typeof s == 'string' && /\?*/.test(s)){s = s.replace(/\#.*/gi,'');}document.write(s);</script>

It's more common answer. And can be use with s= document.location.href;

With Selenium Webdriver would be something like this:

assertTrue(!isElementPresent(By.linkText("Empresas en Misión")));

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

Interestingly, I kept getting that error. What fixed it for me was creating a config called gacutil.exe.config in the same directory as gacutil.exe. The config content (a text file) were:

<?xml version ="1.0"?> <configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <requiredRuntime safemode="true" imageVersion="v4.0.30319" version="v4.0.30319"/>
    </startup> </configuration>

I'm posting this here for reference and ask if anyone knows what's actually happening under the hood. I'm not claiming this is the "proper" way of doing it

Use the display property in CSS:

<body> 
    <div id="invisible" style="display:none;">Invisible DIV</div>  
    <div>Another DIV 
        <button onclick="document.getElementById('invisible').style.display='block'">
            Button
        </button>  
    </div>  
</body>

When the the display of the first div is set back to block it will appear and shift the second div down.

Try

CASE WHEN ebv.db_no IN (22978,23218,23219) THEN 'WECS 9500' ELSE 'WECS 9520' END

If you are willing to use SourceTree (which I strongly recommend), you can right click your branch and chose 'Rename'.

I had the same issue but I've resolved by creating the .gitignore file.

I've also found a workaround that simply consists on removing db.lock file from the .vs folder but you have to do it every single time and doing this for long makes this an annoying operation.

The best way to solve this issue is to create the .gitignore file as suggested before, but I think that is good to mention also this workaround, just to general knowledge purpose!

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

Use:

Open Task Manager ? Processes ? adb.exe ? End Process ? restart Eclipse

This worked for me.

And:

Open Task Manager ? Processes ? eclipse.exe ? End Process ? restart Eclipse

The DBA views are restricted. So you won't be able to query them unless you're connected as a DBA or similarly privileged user.

The ALL views show you the information you're allowed to see. Normally that would be jobs you've submitted, unless you have additional privileges.

The privileges you need are defined in the Admin Guide. Find out more.

So, either you need a DBA account or you need to chat with your DBA team about getting access to the information you need.

SELECT 
(select count(*) from foo1 where ID = '00123244552000258')
+
(select count(*) from foo2 where ID = '00123244552000258')
+
(select count(*) from foo3 where ID = '00123244552000258')

This is an easy way.

You can use CustomMultiChildLayout to draw this kind of layouts. Here you can find a tutorial: How to Create Custom Layout Widgets in Flutter.

You can use Magical Take Photo library.

1. try with compile in gradle

compile 'com.frosquivel:magicaltakephoto:1.0'

2. You need this permission in your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA"/>

3. instance the class like this

// "this" is the current activity param

MagicalTakePhoto magicalTakePhoto =  new MagicalTakePhoto(this,ANY_INTEGER_0_TO_4000_FOR_QUALITY);

4. if you need to take picture use the method

magicalTakePhoto.takePhoto("my_photo_name");

5. if you need to select picture in device, try with the method:

magicalTakePhoto.selectedPicture("my_header_name");

6. You need to override the method onActivityResult of the activity or fragment like this:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);
     magicalTakePhoto.resultPhoto(requestCode, resultCode, data);

     // example to get photo
     // imageView.setImageBitmap(magicalTakePhoto.getMyPhoto());
}

Note: Only with this Library you can take and select picture in the device, this use a min API 15.

func letterize() -> [Character] {
    return Array(self.characters)
}

in addition: for those who have a empty POST variable, don't use this:

name="[levels][level][]"

rather use this (as it is already here in this example):

name="levels[level][]"

I strongly recommend using lowercase field|column names, it will make your life easier.

Let's assume you have a table called users with the following definition and records:

id|firstname|lastname|username             |password
1 |joe      |doe     |[email protected]   |1234
2 |jane     |doe     |[email protected]  |12345
3 |johnny   |doe     |[email protected]|123456

let's say you want to get all records from table users, then you do:

SELECT * FROM users;

Now let's assume you want to select all records from table users, but you're interested only in the fields id, firstname and lastname, thus ignoring username and password:

SELECT id, firstname, lastname FROM users;

Now we get at the point where you want to retrieve records based on condition(s), what you need to do is to add the WHERE clause, let's say we want to select from users only those that have username = [email protected] and password = 1234, what you do is:

SELECT * FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

But what if you need only the id of a record with username = [email protected] and password = 1234? then you do:

SELECT id FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

Now to get to your question, as others before me answered you can use the IN clause:

SELECT * FROM users
WHERE ( id IN (1,2,..,n) );

or, if you wish to limit to a list of records between id 20 and id 40, then you can easily write:

SELECT * FROM users
WHERE ( ( id >= 20 ) AND ( id <= 40 ) );

I hope this gives a better understanding.

Well, getting full path is not possible but we can have a temporary path.

Try This:

It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-

JSFIDDLE

Here is the code :-

HTML:-

<input type="file" id="i_file" value=""> 
<input type="button" id="i_submit" value="Submit">
    <br>
<img src="" width="200" style="display:none;" />
        <br>
<div id="disp_tmp_path"></div>

JS:-

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));

    $("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});

Its not exactly what you were looking for, but may be it can help you somewhere.

If your icon is based on the text in the block (ligatures) rather the class of the block then the following will work. This example uses the Google Material Icons '+' and '-' icons as part of MaterializeCSS.

<a class="btn-class"><i class="material-icons">add</i></a>

$('.btn-class').on('click',function(){
    if ($(this).find('i').text() == 'add'){
        $(this).find('i').text('remove');
    } else {
        $(this).find('i').text('add');
    }
});

Edit: Added missing ); needed for this to function properly.

It also works for JQuery post 1.9 where toggling of functions was deprecated.

np.fliplr() flips the array left to right.

Note that for 1d arrays, you need to trick it a bit:

arr1d = np.array(some_sequence)
reversed_arr = np.fliplr([arr1d])[0]

Another case to use a multi line function would be to circumvent sql server from pushing down the where clause.

For example, I have a table with a table names and some table names are formatted like C05_2019 and C12_2018 and and all tables formatted that way have the same schema. I wanted to merge all that data into one table and parse out 05 and 12 to a CompNo column and 2018,2019 into a year column. However, there are other tables like ACA_StupidTable which I cannot extract CompNo and CompYr and would get a conversion error if I tried. So, my query was in two part, an inner query that returned only tables formatted like 'C_______' then the outer query did a sub-string and int conversion. ie Cast(Substring(2, 2) as int) as CompNo. All looks good except that sql server decided to put my Cast function before the results were filtered and so I get a mind scrambling conversion error. A multi statement table function may prevent that from happening, since it is basically a "new" table.

Just use result_type="expand"

df = pd.DataFrame(np.random.randint(0,10,(10,2)), columns=["random", "a"])
df[["sq_a","cube_a"]] = df.apply(lambda x: [x.a**2, x.a**3], axis=1, result_type="expand")

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

var jsonIssues = []; // new Array
jsonIssues.push( { ID:1, "Name":"whatever" } );
// "push" some more here

The != operator most certainly does exist! It is an alias for the standard <> operator.

Perhaps your fields are not actually empty strings, but instead NULL?

To compare to NULL you can use IS NULL or IS NOT NULL or the null safe equals operator <=>.

I'm recommend using requirejs with AMD javascript class files

good example of how to use it here

http://www.sitepoint.com/understanding-requirejs-for-effective-javascript-module-loading/

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

Edit: In Swift 3:

let indexPath = IndexPath(row: rowIndex, section: sectionIndex)

Swift 5

IndexPath(row: 0, section: 0)

Because timedelta is defined like:

class datetime.timedelta([days,] [seconds,] [microseconds,] [milliseconds,] [minutes,] [hours,] [weeks])

All arguments are optional and default to 0.

You can easily say "Three days and four milliseconds" with optional arguments that way.

>>> datetime.timedelta(days=3, milliseconds=4)
datetime.timedelta(3, 0, 4000)
>>> datetime.timedelta(3, 0, 0, 4) #no need for that.
datetime.timedelta(3, 0, 4000)

And for str casting, it returns a nice formatted value instead of __repr__ to improve readability. From docs:

str(t) Returns a string in the form [D day[s], ][H]H:MM:SS[.UUUUUU], where D is negative for negative t. (5)

>>> datetime.timedelta(seconds = 42).__repr__()
'datetime.timedelta(0, 42)'
>>> datetime.timedelta(seconds = 42).__str__()
'0:00:42'

Checkout documentation:

http://docs.python.org/library/datetime.html#timedelta-objects

Assuming that create_time contains the time the order was created, and you want the 100 clients with the latest orders, you can:

• add the create_time in your innermost query
• order the results of your outer query by the create_time desc
• add an outermost query that filters the first 100 rows using ROWNUM

Query:

  SELECT * FROM (
     SELECT * FROM (
        SELECT 
          id, 
          client_id, 
          create_time,
          ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn 
        FROM order
      ) 
      WHERE rn=1
      ORDER BY create_time desc
  ) WHERE rownum <= 100

UPDATE for Oracle 12c

With release 12.1, Oracle introduced "real" Top-N queries. Using the new FETCH FIRST... syntax, you can also use:

  SELECT * FROM (
    SELECT 
      id, 
      client_id, 
      create_time,
      ROW_NUMBER() OVER(PARTITION BY client_id ORDER BY create_time DESC) rn 
    FROM order
  ) 
  WHERE rn = 1
  ORDER BY create_time desc
  FETCH FIRST 100 ROWS ONLY)

In "build.gradle" file, change current Kotlin version that line and press synk:

ext.kotlin_version = '1.1.1'

/// That will look like:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.1'
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

There is a module called 'pdb' in python. At the top of your python script you do

import pdb
pdb.set_trace()

and you will enter into debugging mode. You can use 's' to step, 'n' to follow next line similar to what you would do with 'gdb' debugger.

Use the bash built-in variable SECONDS. Each time you reference the variable it will return the elapsed time since the script invocation.

Example:

echo "Start $SECONDS"
sleep 10
echo "Middle $SECONDS"
sleep 10
echo "End $SECONDS"

Output:

Start 0
Middle 10
End 20

Every answer uses .next() or uses .beforeFirst() and then .next(). But why not this:

result.first();

So You just set the pointer to the first record and go from there. It's available since java 1.2 and I just wanted to mention this for anyone whose ResultSet exists of one specific record.

To pretty print the column data types

To check the data types after, for example, an import from a file

def printColumnInfo(df):
    template="%-8s %-30s %s"
    print(template % ("Type", "Column Name", "Example Value"))
    print("-"*53)
    for c in df.columns:
        print(template % (df[c].dtype, c, df[c].iloc[1]) )

Illustrative output:

Type     Column Name                    Example Value
-----------------------------------------------------
int64    Age                            49
object   Attrition                      No
object   BusinessTravel                 Travel_Frequently
float64  DailyRate                      279.0

Take a look at Element.getBoundingClientRect().

This method will return an object containing the width, height, and some other useful values:

{
    width: 960,
    height: 71,
    top: 603,
    bottom: 674,
    left: 360,
    right: 1320
}

For Example:

var element = document.getElementById('foo');
var positionInfo = element.getBoundingClientRect();
var height = positionInfo.height;
var width = positionInfo.width;

I believe this does not have the issues that .offsetWidth and .offsetHeight do where they sometimes return 0 (as discussed in the comments here)

Another difference is getBoundingClientRect() may return fractional pixels, where .offsetWidth and .offsetHeight will round to the nearest integer.

IE8 Note: getBoundingClientRect does not return height and width on IE8 and below.*

If you must support IE8, use .offsetWidth and .offsetHeight:

var height = element.offsetHeight;
var width = element.offsetWidth;

Its worth noting that the Object returned by this method is not really a normal object. Its properties are not enumerable (so, for example, Object.keys doesn't work out-of-the-box.)

I translated my Objective-C answer

let start = "2010-09-01"
let end = "2010-09-05"

let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

let startDate:NSDate = dateFormatter.dateFromString(start)
let endDate:NSDate = dateFormatter.dateFromString(end)

let cal = NSCalendar.currentCalendar()


let unit:NSCalendarUnit = .Day

let components = cal.components(unit, fromDate: startDate, toDate: endDate, options: nil)


println(components)

result

<NSDateComponents: 0x10280a8a0>
     Day: 4

The hardest part was that the autocompletion insists fromDate and toDate would be NSDate?, but indeed they must be NSDate! as shown in the reference.

I don't see how a good solution with an operator would look like, as you want to specify the unit differently in each case. You could return the time interval, but than won't you gain much.

You can pass input as ["apple","orange"]if you want to leave the method as it is.

It worked for me with a similar method signature.

Laravel 4.5

Just use

Request::fullUrl()

It will return the full url

You can extract the Querystring with str_replace

str_replace(Request::url(), '', Request::fullUrl())

Or you can get a array of all the queries with

Request::query()

Laravel >5.1

Just use

$request->fullUrl()

It will return the full url

You can extract the Querystring with str_replace

str_replace($request->url(), '',$request->fullUrl())

Or you can get a array of all the queries with

$request->query()

Use val():

 if ($("textarea").val()!== "") {
        alert($("textarea").val());
    }

1. Go to Advanced System Settings in the computer properties
2. Click on Advanced
3. Click for the environment variable
4. Choose the path option
5. Change the path option to bin folder of dev c
6. Apply and save it
7. Now resave the code in the bin folder in developer c

Use NgForm's .resetForm() rather than .reset() because it is the method that is officially documented in NgForm's public api. (Ref [1])

<form (ngSubmit)="mySubmitHandler(); myNgForm.resetForm()" #myNgForm="ngForm">

The .resetForm() method will reset the NgForm's FormGroup and set it's submit flag to false (See [2]).

Tested in @angular versions 2.4.8 and 4.0.0-rc3

You are not putting a " before the end of the line.

Use """ if you want to do this:

""" a very long string ...... 
....that can span multiple lines
"""

It's hard to tell what you're going for in that example. exports = is about exporting from external modules, but the code sample you linked is an internal module.

Rule of thumb: If you write module foo { ... }, you're writing an internal module; if you write export something something at top-level in a file, you're writing an external module. It's somewhat rare that you'd actually write export module foo at top-level (since then you'd be double-nesting the name), and it's even rarer that you'd write module foo in a file that had a top-level export (since foo would not be externally visible).

The following things make sense (each scenario delineated by a horizontal rule):

// An internal module named SayHi with an exported function 'foo'
module SayHi {
    export function foo() {
       console.log("Hi");
    }

    export class bar { }
}

// N.B. this line could be in another file that has a
// <reference> tag to the file that has 'module SayHi' in it
SayHi.foo();
var b = new SayHi.bar();

file1.ts

// This *file* is an external module because it has a top-level 'export'
export function foo() {
    console.log('hi');
}

export class bar { }

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();

file1.ts

// This will only work in 0.9.0+. This file is an external
// module because it has a top-level 'export'
function f() { }
function g() { }
export = { alpha: f, beta: g };

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = require('file1');
f1.alpha(); // invokes f
f1.beta(); // invokes g

There's a tagName property, and a attributes property as well:

var element = document.getElementById("wtv");
var openTag = "<"+element.tagName;
for (var i = 0; i < element.attributes.length; i++) {
    var attrib = element.attributes[i];
    openTag += " "+attrib.name + "=" + attrib.value;
}
openTag += ">";
alert(openTag);

See also How to iterate through all attributes in an HTML element? (I did!)

To get the contents between the open and close tags you could probably use innerHTML if you don't want to iterate over all the child elements...

alert(element.innerHTML);

... and then get the close tag again with tagName.

var closeTag = "</"+element.tagName+">";
alert(closeTag);

For Upload large size data in using phpmyadmin Do following steps.

1. Open php.ini file from C:\wamp\bin\apache\Apache2.4.4\bin Update following lines

   max_execution_time = 259200
   max_input_time = 259200
   memory_limit = 1000M
   upload_max_filesize = 750M
   post_max_size = 750M

   than after restart wamp server or restart all services Now Upload data using import function in phymyadmin. Apply second step if till not upload data.
   
2. open config.default.php file in c:\wamp\apps\phpmyadmin4.0.4\libraries (Open this file accoring to phpmyadmin version)
   Find $cfg['ExecTimeLimit'] = 300;Replace to $cfg['ExecTimeLimit'] = 0;
   Now you can upload data.

You can also upload large size database using MySQL Console as below.

1. Click on WampServer Icon -> MySQL -> MySQL Consol
2. Enter your database password like root in popup
3. Select database name for insert data by writing command USE DATABASENAME
4. Then load source sql file as SOURCE C:\FOLDER\database.sql
5. Press enter for insert data.

Note: You can't load a compressed database file e.g. database.sql.zip or database.sql.gz, you have to extract it first. Otherwise the console will just crash.

This solution has really helped me :

By using below two methods we can clear data programatically

    public void clearApplicationData() {
    File cacheDirectory = getCacheDir();
    File applicationDirectory = new File(cacheDirectory.getParent());
    if (applicationDirectory.exists()) {
    String[] fileNames = applicationDirectory.list();
        for (String fileName : fileNames) {
            if (!fileName.equals("lib")) {
                deleteFile(new File(applicationDirectory, fileName));
            }
        }
    }
}
    public static boolean deleteFile(File file) {
    boolean deletedAll = true;
    if (file != null) {
        if (file.isDirectory()) {
            String[] children = file.list();
            for (int i = 0; i < children.length; i++) {
                deletedAll = deleteFile(new File(file, children[i])) && deletedAll;
            }
        } else {
            deletedAll = file.delete();
        }
    }

    return deletedAll;
}

You can use the jQuery attribute selector:

$('td[name ="tcol1"]')   // matches exactly 'tcol1'
$('td[name^="tcol"]' )   // matches those that begin with 'tcol'
$('td[name$="tcol"]' )   // matches those that end with 'tcol'
$('td[name*="tcol"]' )   // matches those that contain 'tcol'

From Install Curl Extension for PHP in Ubuntu:

sudo apt-get install php5-curl

After installing libcurl, you should restart the web server with one of the following commands,

sudo /etc/init.d/apache2 restart

or

sudo service apache2 restart

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

You say it's not working. What are you expecting to happen?

There's no way of getting the data out of a FormData object; it's just intended for you to use to send data along with an XMLHttpRequest object (for the send method).

Update almost five years later: In some newer browsers, this is no longer true and you can now see the data provided to FormData in addition to just stuffing data into it. See the accepted answer for more info.

Here's a controversial option:

String.prototype.includesOneOf = function(arrayOfStrings) {
  if(!Array.isArray(arrayOfStrings)) {
    throw new Error('includesOneOf only accepts an array')
  }
  return arrayOfStrings.some(str => this.includes(str))
}

Allowing you to do things like:

'Hi, hope you like this option'.toLowerCase().includesOneOf(["hello", "hi", "howdy"]) // True

I have a Samsung Duos device with Android 4.4.4 and the method suggested by Seetha in the accepted answer (i.e. call getDeviceIdDs) does not work for me, as the method does not exist. I was able to recover all the information I needed by calling method "getDefault(int slotID)", as shown below:

public static void samsungTwoSims(Context context) {
    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

    try{

        Class<?> telephonyClass = Class.forName(telephony.getClass().getName());

        Class<?>[] parameter = new Class[1];
        parameter[0] = int.class;
        Method getFirstMethod = telephonyClass.getMethod("getDefault", parameter);

        Log.d(TAG, getFirstMethod.toString());

        Object[] obParameter = new Object[1];
        obParameter[0] = 0;
        TelephonyManager first = (TelephonyManager) getFirstMethod.invoke(null, obParameter);

        Log.d(TAG, "Device Id: " + first.getDeviceId() + ", device status: " + first.getSimState() + ", operator: " + first.getNetworkOperator() + "/" + first.getNetworkOperatorName());

        obParameter[0] = 1;
        TelephonyManager second = (TelephonyManager) getFirstMethod.invoke(null, obParameter);

        Log.d(TAG, "Device Id: " + second.getDeviceId() + ", device status: " + second.getSimState()+ ", operator: " + second.getNetworkOperator() + "/" + second.getNetworkOperatorName());
    } catch (Exception e) {
        e.printStackTrace();
    }   
}

Also, I rewrote the code that iteratively tests for methods to recover this information so that it uses an array of method names instead of a sequence of try/catch. For instance, to determine if we have two active SIMs we could do:

private static String[] simStatusMethodNames = {"getSimStateGemini", "getSimState"};


public static boolean hasTwoActiveSims(Context context) {
    boolean first = false, second = false;

    for (String methodName: simStatusMethodNames) {
        // try with sim 0 first
        try {
            first = getSIMStateBySlot(context, methodName, 0);
            // no exception thrown, means method exists
            second = getSIMStateBySlot(context, methodName, 1);
           return first && second;
        } catch (GeminiMethodNotFoundException e) {
            // method does not exist, nothing to do but test the next
        }
    }
    return false;
}

This way, if a new method name is suggested for some device, you can simply add it to the array and it should work.
