AWS added a new feature to connect to instance without any open port, the AWS SSM Session Manager. https://aws.amazon.com/blogs/aws/new-session-manager/

I've created a neat SSH ProxyCommand script that temporary adds your public ssh key to target instance during connection to target instance. The nice thing about this is you will connect without the need to add the ssh(22) port to your security groups, because the ssh connection is tunneled through ssm session manager.

Check against any long running queries in your database.

Increasing your pool size will only make your webapp live a little longer (and probably get a lot slower)

You can use sql server profiler and filter on duration / reads to see which querys need optimization.

I also see you're probably keeping a global connection?

blnMainConnectionIsCreatedLocal

Let .net do the pooling for you and open / close your connection with a using statement.

Suggestions:

1. Always open and close a connection like this, so .net can manage your connections and you won't run out of connections:

       using (SqlConnection conn = new SqlConnection(connectionString))
       {
        conn.Open();
        // do some stuff
       } //conn disposed
   

2. As I mentioned, check your query with sql server profiler and see if you can optimize it. Having a slow query with many requests in a web app can give these timeouts too.

NewScores is an alias to Scores table - it looks like you can combine the queries as follows:

SELECT 
    ROW_NUMBER() OVER( ORDER BY NETT) AS Rank, 
    Name, 
    FlagImg, 
    Nett, 
    Rounds 
FROM (
    SELECT 
        Members.FirstName + ' ' + Members.LastName AS Name, 
        CASE 
            WHEN MenuCountry.ImgURL IS NULL THEN 
                '~/images/flags/ismygolf.png' 
            ELSE 
                MenuCountry.ImgURL 
        END AS FlagImg, 
        AVG(CAST(NewScores.NetScore AS DECIMAL(18, 4))) AS Nett, 
        COUNT(Score.ScoreID) AS Rounds 
    FROM 
        Members 
        INNER JOIN 
        Score NewScores
            ON Members.MemberID = NewScores.MemberID 
        LEFT OUTER JOIN MenuCountry 
            ON Members.Country = MenuCountry.ID 
    WHERE 
        Members.Status = 1 
        AND NewScores.InsertedDate >= DATEADD(mm, -3, GETDATE())
    GROUP BY 
        Members.FirstName + ' ' + Members.LastName, 
        MenuCountry.ImgURL
    ) AS Dertbl 
ORDER BY;

Definitely the easiest way to do that is using Gson's default parsing function fromJson().

There is an implementation of this function suitable for when you need to deserialize into any ParameterizedType (e.g., any List), which is fromJson(JsonElement json, Type typeOfT).

In your case, you just need to get the Type of a List<String> and then parse the JSON array into that Type, like this:

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;

JsonElement yourJson = mapping.get("servers");
Type listType = new TypeToken<List<String>>() {}.getType();

List<String> yourList = new Gson().fromJson(yourJson, listType);

In your case yourJson is a JsonElement, but it could also be a String, any Reader or a JsonReader.

You may want to take a look at Gson API documentation.

This is because keypress events are fired before the new character is added to the value of the element (so the first keypress event is fired before the first character is added, while the value is still empty). You should use keyup instead, which is fired after the character has been added.

Note that, if your element #dSuggest is the same as input:text[name=dSuggest] you can simplify this code considerably (and if it isn't, having an element with a name that is the same as the id of another element is not a good idea).

$('#dSuggest').keypress(function() {
    var dInput = this.value;
    console.log(dInput);
    $(".dDimension:contains('" + dInput + "')").css("display","block");
});

if myProp is an object, it may not be changed in usual. so, watch will never be triggered. the reason of why myProp not be changed is that you just set some keys of myProp in most cases. the myProp itself is still the one. try to watch props of myProp, like "myProp.a",it should work.

Updating this topic with a more recent answer, solution that worked for me with version 8.0 of MySQL Connector/ODBC (downloaded at https://downloads.mysql.com/archives/c-odbc/):

Public oConn As ADODB.Connection
Sub MySqlInit()
    If oConn Is Nothing Then
        Dim str As String
        str = "Driver={MySQL ODBC 8.0 Unicode Driver};SERVER=xxxxx;DATABASE=xxxxx;PORT=3306;UID=xxxxx;PWD=xxxxx;"
        Set oConn = New ADODB.Connection
        oConn.Open str
    End If
End Sub

The most important thing on this matter is to check the proper name and version of the installed driver at: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers\

This is easy to fix.

• Changes to the Launcher activity are also stored in the Debug configuration.
• Go to Run > Debug Configurations and edit the setting.
• There is also a similar setting in Intellij under Run > Edit Configurations select Run default Activity and it will no longer save the setting in this fashion.

It might be better to use communicate:

from subprocess import Popen, PIPE, STDOUT
p = Popen(['myapp'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
stdout_data = p.communicate(input='data_to_write')[0]

"Better", because of this warning:

Use communicate() rather than .stdin.write, .stdout.read or .stderr.read to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

If you can open the http://localhost:8088/cluster but can't open http://localhost:50070/. Maybe datanode didn't start-up or namenode didn't formate.

Hadoop version 2.6.4

• step 1:

check whether your namenode has been formated, if not type:

$ stop-all.sh
$ /path/to/hdfs namenode -format
$ start-all.sh

• step 2:

check your namenode tmp file path, to see in /tmp, if the namenode directory is in /tmp, you need set tmp path in core-site.xml, because every time when you reboot or start your machine, the files in /tmp will be removed, you need set a tmp dir path.

add the following to it.

<property>
    <name>hadoop.tmp.dir</name>
    <value>/path/to/hadoop/tmp</value>
</property>

• step 3:

check step 2, stop hadoop and remove the namenode tmp dir in /tmp, then type /path/to/hdfs namenode -format, and start the hadoop. The is also a tmp dir in $HADOOP_HOME

If all the above don't help, please comment below!

Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

If you:

 git push origin master

it will push to the bare repo.

It sounds like your alice repo isn't tracking correctly.

cat .git/config

This will show the default remote and branch.

If you

 git push -u origin master

You should start tracking that remote and branch. I'm not sure if that option has always been in git.

i came across a similar situation using booleans where I wanted to avoid calling b() if a was already false.

This worked for me:

a &= a && b()

To prevent this, make sure every BEGIN TRANSACTION has COMMIT

The following will say successful but will leave uncommitted transactions:

BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT

Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.

The best way I found is, download a dll from here

Then, add the dll to your project.

Then, add code:

[DllImportAttribute("HardwareIDExtractorC.dll")]
public static extern String GetIDESerialNumber(byte DriveNumber);

Then, call the hard disk ID from where you need it

GetIDESerialNumber(0).Replace(" ", string.Empty);

Note: go to properties of the dll in explorer and set "Build action" to "Embedded Resource"

for (int i = 0; i < 5; i++){
    int asciiVal = rand()%26 + 97;
    char asciiChar = asciiVal;
    cout << asciiChar << " and ";
}

Use a max_allowed_packet variable issuing a command like

mysql --max_allowed_packet=32M -u root -p database < dump.sql

I'm going to break from the herd on this one and provide an alternate point of view:

Never create classes.

Reliance on classes has a significant tendency to cause coders to create bloated and slow code. Classes getting passed around (since they're objects) take a lot more computational power than calling a function and passing a string or two. Proper naming conventions on functions can do pretty much everything creating a class can do, and with only a fraction of the overhead and better code readability.

That doesn't mean you shouldn't learn to understand classes though. If you're coding with others, people will use them all the time and you'll need to know how to juggle those classes. Writing your code to rely on functions means the code will be smaller, faster, and more readable. I've seen huge sites written using only functions that were snappy and quick, and I've seen tiny sites that had minimal functionality that relied heavily on classes and broke constantly. (When you have classes extending classes that contain classes as part of their classes, you know you've lost all semblance of easy maintainability.)

When it comes down to it, all data you're going to want to pass can easily be handled by the existing datatypes.

Classes were created as a mental crutch and provide no actual extra functionality, and the overly-complicated code they have a tendency to create defeats the point of that crutch in the long run.

For Windows (7), the same folder is located at,

%APPDATA%\Subversion\auth

Type in the above in the Run(Win key + R) dialog box and hit Enter,

To check the existing username open the below file as a text file,

%APPDATA%\Subversion\auth\svn.simple\xxxxxxxxxx

The keyword for Oracle PL/SQL is "ELSIF" ( no extra "E"), not ELSEIF (yes, confusing and stupid)

declare
    var_number number;
begin
    var_number := 10;
    if var_number > 100 then
       dbms_output.put_line(var_number||' is greater than 100');
    elsif var_number < 100 then
       dbms_output.put_line(var_number||' is less than 100');
    else
       dbms_output.put_line(var_number||' is equal to 100');
    end if;
end;

Is this value intended? if (scroll <= 500) { ... This means it's happening from 0 to 500, and not 500 and greater. In the original post you said "after the user scrolls down a little"

I solved this by overriding the default Content-Type:

const config = { headers: {'Content-Type': 'application/json'} };
axios.put(url, content, config).then(response => {
    ...
});

Based on m experience, the default Conent-Type is application/x-www-form-urlencoded for strings, and application/json for objects (including arrays). Your server probably expects JSON.

I understand why the Rails devs went with sqlite3 for an out-of-the-box implementation, but MySQL is so much more practical, IMHO. I realize it depends on what you are building your Rails app for, but most people are going to switch the default database.yml file from sqlite3 to MySQL.

Glad you resolved your issue.

Also:

(value % 1) == 0

would work!

Okey , so its a basic problem , dont worry about this just write the <View> component and wrap it around the <Text> component

<View style={{alignItems: 'center'}}>
<Text> Write your Text Here</Text>
</View>

alignitems:center is a prop use to center items on crossaxis

justifycontent:'center' is a prop use to center items on mainaxis

Enhancement to Alexis King's code to run without Jquery and removal of empty arrays and array of empty objects (With no properties) recursively.

size_t ln = strlen(name) - 1;
if (*name && name[ln] == '\n') 
    name[ln] = '\0';

It must be noted that there is also a considerable interest in Wicket and Scala. Wicket fits Scala suprisingly well. If you want to take advantage of the very mature Wicket project and its ecosystem (extensions) plus the concise syntax and productivity advantage of Scala, this one may be for you!

I think that this is an old error that you tried to fix by importing random things in your module and now the code does not compile anymore. while you don't pay attention to the shell output, the browser reload, and you still get the same error.

Your module should be :

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ],
  declarations: [
    ContactComponent
  ]
})
export class ContactModule {}

You can use an array in the select() to define more columns and you can use the DB::raw() there with aliasing it to followers. Should look like this:

$query = DB::table('category_issue')
    ->select(array('issues.*', DB::raw('COUNT(issue_subscriptions.issue_id) as followers')))
    ->where('category_id', '=', 1)
    ->join('issues', 'category_issue.issue_id', '=', 'issues.id')
    ->left_join('issue_subscriptions', 'issues.id', '=', 'issue_subscriptions.issue_id')
    ->group_by('issues.id')
    ->order_by('followers', 'desc')
    ->get();

The assertNotNull() method means "a passed parameter must not be null": if it is null then the test case fails.
The assertNull() method means "a passed parameter must be null": if it is not null then the test case fails.

String str1 = null;
String str2 = "hello";              

// Success.
assertNotNull(str2);

// Fail.
assertNotNull(str1);

// Success.
assertNull(str1);

// Fail.
assertNull(str2);

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

Incase you want to mimic what php function htmlspecialchars_decode does use php function get_html_translation_table() to dump the table and then use the java code like,

static Map<String,String> html_specialchars_table = new Hashtable<String,String>();
static {
        html_specialchars_table.put("&lt;","<");
        html_specialchars_table.put("&gt;",">");
        html_specialchars_table.put("&amp;","&");
}
static String htmlspecialchars_decode_ENT_NOQUOTES(String s){
        Enumeration en = html_specialchars_table.keys();
        while(en.hasMoreElements()){
                String key = en.nextElement();
                String val = html_specialchars_table.get(key);
                s = s.replaceAll(key, val);
        }
        return s;
}

Android Context has the following method:

public abstract boolean deleteFile (String name)

I believe this will do what you want with the right App premissions as listed above.

Sending Data Back

It helps me to see things in context. Here is a complete simple project for sending data back. Rather than providing the xml layout files, here is an image.

Main Activity

• Start the Second Activity with startActivityForResult, providing it an arbitrary result code.
• Override onActivityResult. This is called when the Second Activity finishes. You can make sure that it is actually the Second Activity by checking the request code. (This is useful when you are starting multiple different activities from the same main activity.)
• Extract the data you got from the return Intent. The data is extracted using a key-value pair.

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private static final int SECOND_ACTIVITY_REQUEST_CODE = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    // "Go to Second Activity" button click
    public void onButtonClick(View view) {

        // Start the SecondActivity
        Intent intent = new Intent(this, SecondActivity.class);
        startActivityForResult(intent, SECOND_ACTIVITY_REQUEST_CODE);
    }

    // This method is called when the second activity finishes
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // Check that it is the SecondActivity with an OK result
        if (requestCode == SECOND_ACTIVITY_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {

                // Get String data from Intent
                String returnString = data.getStringExtra("keyName");

                // Set text view with string
                TextView textView = (TextView) findViewById(R.id.textView);
                textView.setText(returnString);
            }
        }
    }
}

Second Activity

• Put the data that you want to send back to the previous activity into an Intent. The data is stored in the Intent using a key-value pair.
• Set the result to RESULT_OK and add the intent holding your data.
• Call finish() to close the Second Activity.

SecondActivity.java

public class SecondActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
    }

    // "Send text back" button click
    public void onButtonClick(View view) {

        // Get the text from the EditText
        EditText editText = (EditText) findViewById(R.id.editText);
        String stringToPassBack = editText.getText().toString();

        // Put the String to pass back into an Intent and close this activity
        Intent intent = new Intent();
        intent.putExtra("keyName", stringToPassBack);
        setResult(RESULT_OK, intent);
        finish();
    }
}

Other notes

• If you are in a Fragment it won't know the meaning of RESULT_OK. Just use the full name: Activity.RESULT_OK.

See also

• Fuller answer that includes passing data forward
• Naming Conventions for the Key String

You should treat it as an array like this,

<input name="checkbox[]" type="checkbox" value="<?php echo $row['link_id']; ?>">

Then only, you can take its count and loop it for deletion.

You also need to pass the database connection to the query.

$result = mysqli_query($dbc, $sql);

Yours did not include it:

$result = mysqli_query($sql);

catching in this fashion, in my experience, is dangerous. Any error thrown in the entire stack will be caught, not just an error from this promise (which is probably not what you want).

The second argument to a promise is already a rejection/failure callback. It's better and safer to use that instead.

Here's a typescript typesafe one-liner I wrote to handle this:

function wait<R, E>(promise: Promise<R>): [R | null, E | null] {
  return (promise.then((data: R) => [data, null], (err: E) => [null, err]) as any) as [R, E];
}

// Usage
const [currUser, currUserError] = await wait<GetCurrentUser_user, GetCurrentUser_errors>(
  apiClient.getCurrentUser()
);

Try the following:

    ....
    character(len=30) :: filename  ! length depends on expected names
    integer           :: inuit
    ....
    do i=1,n
        write(filename,'("output",i0,".txt")') i
        open(newunit=iunit,file=filename,...)
        ....
        close(iunit)
    enddo
    ....

Where "..." means other appropriate code for your purpose.

Using the otherwise pointless ? : operator to initialise a const variable

const int bytesPerPixel = isAlpha() ? 4 : 3;

I recently put all my source on a windows 8 32 box. Had the issues loading mscomctl.ocx with existing projects.

I created a new project and add the common control (all). save the project and reloaded it no problem.

when you compare the project headers new vs old the old one uses reference=*\blah blah. I found removing this a replacing it with the Object={blah} sorted out the problem.

it should be :

$_SERVER['REQUEST_URI'];

Take a look at : Get the full URL in PHP

@Acyra- performance of object delivery from a single bucket would depend greatly on the names of the objects in it.

If the file names were distanced by random characters then their physical locations would be spread further on the AWS hardware, but if you named everything 'common-x.jpg', 'common-y.jpg' then those objects will be stored together.

This may slow delivery of the files if you request them simultaneously but not by enough to worry you, the greater risk is from data-loss or an outage, since these objects are stored together they will be lost or unavailable together.

I find this one works well for a "FullName":

([a-z',.-]+( [a-z',.-]+)*){1,70}/

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

http://www.postgresql.org/docs/current/static/catalog-pg-extension.html

The solution works good except if you have a Web Service.

You would need to do the Following as the Description Attribute is not serializable.

[DataContract]
public enum ControlSelectionType
{
    [EnumMember(Value = "Not Applicable")]
    NotApplicable = 1,
    [EnumMember(Value = "Single Select Radio Buttons")]
    SingleSelectRadioButtons = 2,
    [EnumMember(Value = "Completely Different Display Text")]
    SingleSelectDropDownList = 3,
}

public static string GetDescriptionFromEnumValue(Enum value)
{
        EnumMemberAttribute attribute = value.GetType()
            .GetField(value.ToString())
            .GetCustomAttributes(typeof(EnumMemberAttribute), false)
            .SingleOrDefault() as EnumMemberAttribute;
        return attribute == null ? value.ToString() : attribute.Value;
}

Schema in SQL Server is an object that conceptually holds definitions for other database objects such as tables,views,stored procedures etc.

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

you may also go for a simple View.OnClickListener:

satView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if(((CompoundButton) view).isChecked()){
            System.out.println("Checked");
        } else {
            System.out.println("Un-Checked");
        }
    }
});

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

its tempting say as white space or integer 0 as per below proof

char c1 = '\u0000';
System.out.println("*"+c1+"*");
System.out.println((int)c1);

but i wouldn't say so because, it might differ it different platforms or in future. What i really care is i ll never use this default value, so before using any char just check it is \u0000 or not, then use it to avoid misconceptions in programs. Its as simple as that.

To complement Michael's answer, and according to this answer, a safe way to deal with the problem is to use the following arguments:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:+UseConcMarkSweepGC

Several possibilities:

• You have safe mode enabled. That way, only exec() is working, and then only on executables in safe_mode_exec_dir
• exec and shell_exec are disabled in php.ini
• The path to the executable is wrong. If the script is in the same directory as the php file, try exec(dirname(__FILE__) . '/myscript.sh');

What am I missing?

Why not:

url.split('?')[0] 

(Assuming you are looking at the reports in the Crystal Report Designer...)

Your menu options might be a little different depending on the version of Crystal Reports you're using, but you can either:

• Make a summary field: Right-click on the desired formula field in your detail section and choose "Insert Summary". Choose "sum" from the drop-down box and verify that the correct account grouping is selected, then click OK. You will then have a simple sum field in your group footer section.
• Make a running total field: Click on the "Insert" menu and choose "Running Total Field..."*** Click on the New button and give your new running total field a name. Choose your formula field under "Field to summarize" and choose "sum" under "Type of Summary". Here you can also change when the total is evaluated and reset, leave these at their default if you're wanting a sum on each record. You can also use a formula to determine when a certain field should be counted in the total. (Evaluate: Use Formula)

You can use Python-dateutil's relativedelta to increment a datetime object while remaining sensitive to things like leap years and month lengths. Python-dateutil comes packaged with matplotlib if you already have that. You can do the following:

from dateutil.relativedelta import relativedelta

new_date = old_date + relativedelta(years=1)

(This answer was given by @Max to a similar question).

But if your date is a string (i.e. not already a datetime object) you can convert it using datetime:

from datetime import datetime
from dateutil.relativedelta import relativedelta

your_date_string = "April 1, 2012"
format_string = "%B %d, %Y"

datetime_object = datetime.strptime(your_date_string, format_string).date()
new_date = datetime_object + relativedelta(years=1)
new_date_string = datetime.strftime(new_date, format_string).replace(' 0', ' ')

new_date_string will contain "April 1, 2013".

NB: Unfortunately, datetime only outputs day values as "decimal numbers" - i.e. with leading zeros if they're single digit numbers. The .replace() at the end is a workaround to deal with this issue copied from @Alex Martelli (see this question for his and other approaches to this problem).

you can save the model in json and weights in a hdf5 file format.

# keras library import  for Saving and loading model and weights

from keras.models import model_from_json
from keras.models import load_model

# serialize model to JSON
#  the keras model which is trained is defined as 'model' in this example
model_json = model.to_json()


with open("model_num.json", "w") as json_file:
    json_file.write(model_json)

# serialize weights to HDF5
model.save_weights("model_num.h5")

files "model_num.h5" and "model_num.json" are created which contain our model and weights

To use the same trained model for further testing you can simply load the hdf5 file and use it for the prediction of different data. here's how to load the model from saved files.

# load json and create model
json_file = open('model_num.json', 'r')

loaded_model_json = json_file.read()
json_file.close()
loaded_model = model_from_json(loaded_model_json)

# load weights into new model
loaded_model.load_weights("model_num.h5")
print("Loaded model from disk")

loaded_model.save('model_num.hdf5')
loaded_model=load_model('model_num.hdf5')

To predict for different data you can use this

loaded_model.predict_classes("your_test_data here")

This works when I try it. I double-checked with two sample programs:

using System;
using System.Diagnostics;

namespace ConsoleApplication1 {
  class Program {
    static void Main(string[] args) {
      Process.Start("ConsoleApplication2.exe");
    }
  }
}

using System;
using System.IO;

namespace ConsoleApplication2 {
  class Program {
    static void Main(string[] args) {
      try {
        File.WriteAllText(@"c:\program files\test.txt", "hello world");
      }
      catch (Exception ex) {
        Console.WriteLine(ex.ToString());
        Console.ReadLine();
      }
    }
  }
}

First verified that I get the UAC bomb:

System.UnauthorizedAccessException: Access to the path 'c:\program files\test.txt' is denied.
// etc..

Then added a manifest to ConsoleApplication1 with the phrase:

    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

No bomb. And a file I can't easily delete :) This is consistent with several previous tests on various machines running Vista and Win7. The started program inherits the security token from the starter program. If the starter has acquired admin privileges, the started program has them as well.

you can use the command prompt:

javaw.exe -jar yourfile.jar

Hope it works for you.

dict.iteritems(): gives you an iterator. You may use the iterator in other patterns outside of the loop.

student = {"name": "Daniel", "student_id": 2222}

for key,value in student.items():
    print(key,value)

('student_id', 2222)
('name', 'Daniel')

for key,value in student.iteritems():
    print(key,value)

('student_id', 2222)
('name', 'Daniel')

studentIterator = student.iteritems()

print(studentIterator.next())
('student_id', 2222)

print(studentIterator.next())
('name', 'Daniel')

IMHO, a very nice solution is to use c++11 emplace_back function:

revenue.emplace_back("string", map[i].second);

It just creates a new element in place.

After search alot, finaly i found simple here https://www.wpf-tutorial.com/listview-control/listview-how-to-column-sorting/

    yourListView.Items.SortDescriptions.Clear();
  }

  ListSortDirection newDir = ListSortDirection.Ascending;
  if (listViewSortCol == column && listViewSortAdorner.Direction == newDir)
    newDir = ListSortDirection.Descending;

  listViewSortCol = column;
  listViewSortAdorner = new SortAdorner(listViewSortCol, newDir);
  AdornerLayer.GetAdornerLayer(listViewSortCol).Add(listViewSortAdorner);
  yourListView.Items.SortDescriptions.Add(new SortDescription(sortBy, newDir));

The problem is not the range, the problem is how the end of slice is calculated. with a fixed number 10 the simple for loop is ok but with a calculated size like bfl.Size() you get a function-call on every iteration. A simple range over int32 would help because this evaluate the bfl.Size() only once.

type BFLT PerfServer   
  func (this *BFLT) Call() {
    bfl := MqBufferLCreateTLS(0)                                                                                   
    for this.ReadItemExists() {                                                                                    
      bfl.AppendU(this.ReadU())                                                                                    
    }
    this.SendSTART()
    // size := bfl.Size() 
    for i := int32(0); i < bfl.Size() /* size */; i++ {                                                                             
      this.SendU(bfl.IndexGet(i))                                                                                  
    }
    this.SendRETURN()
  }

mkdir foo works even if the directory exists. To make it work only if the directory named "foo" does not exist, try using the -p flag.

Example:

mkdir -p foo

This will create the directory named "foo" only if it does not exist. :)

You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ] will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ].
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)

In your case, I would use shell form

ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"

Below query will provide exactly the same result as given in the desired response:

    },
    {
        $group: {
            _id: "$_id.addresses",
            bookCounts: { $push: { bookName: "$_id.books",count: "$num" } }

        {
            "bookName" : "book5",
            "count" : 1
        }
    ],
    "totalBookAtAddress" : 3
},

/* 8 */
{
    "_id" : "address77",
    "bookCounts" : [
        {
            "bookName" : "book11",
            "count" : 1
        }
    ],
    "totalBookAtAddress" : 1
},

/* 9 */
{
    "_id" : "address9",
    "bookCounts" : [
        {
            "bookName" : "book99",
            "count" : 1
        }
    ],
    "totalBookAtAddress" : 1
}

This will create a Date exactly one year in the future with just one line. First we get the fullYear from a new Date, increment it, set that as the year of a new Date. You might think we'd be done there, but if we stopped it would return a timestamp, not a Date object so we wrap the whole thing in a Date constructor.

new Date(new Date().setFullYear(new Date().getFullYear() + 1))

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

You can simply use this function with save() JPAfunction, but the object sent as parameter must contain an existing id in the database otherwise it will not work, because save() when we send an object without id, it adds directly a row in database, but if we send an object with an existing id, it changes the columns already found in the database.

public void updateUser(Userinfos u) {
    User userFromDb = userRepository.findById(u.getid());
    // crush the variables of the object found
    userFromDb.setFirstname("john"); 
    userFromDb.setLastname("dew");
    userFromDb.setAge(16);
    userRepository.save(userFromDb);
}

You need to use a while loop. If you make a while loop, and there's no instruction after the loop, it'll become an infinite loop,and won't stop until you manually stop it.

Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.

You'll need to unpack the file or use it directly.

If you have a Context, you can use context.getAssets().open("myfoldername/myfilename"); to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File).

The best use of tags you should use:

<img src="" alt=""/>

Also you can use in HTML5:

<img src="" alt="">

These two are completely valid in HTML5 Pick one of them and stick with that.

If you want to dynamicallly display your Symfony 2 version in pages, for example in footer, you can do it this way.

Create a service:

<?php

namespace Project\Bundle\DuBundle\Twig;

class SymfonyVersionExtension extends \Twig_Extension
{


 public function getFunctions()
 {
 return array(
 //this is the name of the function you will use in twig
 new \Twig_SimpleFunction('symfony_version', array($this, 'b'))
   );
 }

public function getName()
{
//return 'number_employees';
 return 'symfony_version_extension';
}   

public function b()
{
 $symfony_version = \Symfony\Component\HttpKernel\Kernel::VERSION;
 return $symfony_version;
}
}

Register in service.yml

 dut.twig.symfony_version_extension:
    class: Project\Bundle\DutBundle\Twig\SymfonyVersionExtension
    tags:
        - { name: twig.extension }
    #arguments: []

And you can call it anywhere. In Controller, wrap it in JSON, or in pages example footer

 <p> Built With Symfony {{ symfony_version() }} Version MIT License</p>

Now every time you run composer update to update your vendor, symfony version will also automatically update in your template.I know this is overkill but this is how I do it in my projects and it is working.

You can use this property : vertical-align:middle;

.selector-class { 
    float:left;
    vertical-align:middle; 
} 

I had two significant errors in my program. From the other answers, I learned in a single java program, one can not declare two classes as "public". So I changed the access specifier, but got another error as added to my question as "EDIT" that "Selection does not contain a main type". Finally I observed I forgot to add "String args[]" part in my main method. That's why the code was not working. After rectification, it worked as expected.

To let MySql generate sequence numbers for an AUTO_INCREMENT field you have three options:

1. specify list a column list and omit your auto_incremented column from it as njk suggested. That would be the best approach. See comments.
2. explicitly assign NULL
3. explicitly assign 0

3.6.9. Using AUTO_INCREMENT:

...No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

These three statements will produce the same result:

$insertQuery = "INSERT INTO workorders (`priority`, `request_type`) VALUES('$priority', '$requestType', ...)";
$insertQuery = "INSERT INTO workorders VALUES(NULL, '$priority', ...)";
$insertQuery = "INSERT INTO workorders VALUES(0, '$priority', ...";

I just want to have a button on my website make a PHP file run

<form action="my.php" method="post">
    <input type="submit">
</form>

Generally speaking, however, unless you are sending new data to the server to be stored, you would just use a link.

<a href="my.php">run php</a>

(Although you should use link text that describes what happens from the user's point of view, not the servers)

I'm making a simple blog site for myself and I've got the code for the site and the javascript that can take the post I write in a textarea and display it immediately. I just want to link it to a PHP file that will create the permanent blog post on the server so that when I reload the page, the post is still there.

This is tricker.

First, you do need to use a form and POST (since you are sending data to be stored).

Then you need to store the data somewhere. This is normally done using a database. Read up on the PDO library for PHP. It is the standard way to interact with databases.

Then you need to pull the data back out again. The simplest approach here is to use the query string to pass the primary key for the database row with the entry you wish to display.

<a href="showBlogEntry.php?entry_id=123">...</a>

Make sure you also read up on SQL injection and XSS.

<th nowrap="nowrap">

or

<th style="white-space:nowrap;">

or

<th class="nowrap">
<style type="text/css">
.nowrap { white-space: nowrap; }
</style>

I haven't seen this done before, but this is how it was done for emulating IE 8/7 when using IE 9:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">

If not, then try this one:

<meta http-equiv="X-UA-Compatible" content="IE=9">

Add those to your header with the other meta tags. This should force IE10 to render as IE9.

Another option you could do (assuming you are using PHP) is add this to your .htaccess file:

Header set X-UA-Compatible "IE=9"

This will perform the action universally, rather than having to worry about adding the meta tag to all of your headers.

There's a static method in ToolStripRenderer class, named CreateDisabledImage. Its usage is as simple as:

Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);

It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.

You should check if the POST['username'] is defined. Use this above:

$username = "";

if(isset($_POST['username'])){
    $username = $_POST['username'];
}

"SELECT password FROM users WHERE username='".$username."'"

Just for completeness, there is also the LINQ/Lambda way:

myMoney.ForEach((theMoney) => Console.WriteLine("amount is {0}, and type is {1}", theMoney.amount, theMoney.type));

this is pretty useful:

https://github.com/JedWatson/classnames

You can do stuff like

classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'

// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'

or use it like this

var btnClass = classNames('btn', this.props.className, {
  'btn-pressed': this.state.isPressed,
  'btn-over': !this.state.isPressed && this.state.isHovered
});

Use pandas:

import pandas as pd
my_csv = pd.read_csv(filename)
column = my_csv.column_name
# you can also use my_csv['column_name']

Discard unneeded columns at parse time:

my_filtered_csv = pd.read_csv(filename, usecols=['col1', 'col3', 'col7'])

P.S. I'm just aggregating what other's have said in a simple manner. Actual answers are taken from here and here.

ls | xargs find 2>/dev/null | egrep /\.git$ | xargs rm -rf

This command (and it is just one command) will recursively remove .git directories (and files) that are in a directory without deleting the top-level git repo, which is handy if you want to commit all of your files without managing any submodules.

find 2>/dev/null | egrep /\.git$ | xargs rm -rf

This command will do the same thing, but will also delete the .git folder from the top-level directory.

You can use the Y-combinator: (Wikipedia)

// ES5 syntax
var Y = function Y(a) {
  return (function (a) {
    return a(a);
  })(function (b) {
    return a(function (a) {
      return b(b)(a);
    });
  });
};

// ES6 syntax
const Y = a=>(a=>a(a))(b=>a(a=>b(b)(a)));

// If the function accepts more than one parameter:
const Y = a=>(a=>a(a))(b=>a((...a)=>b(b)(...a)));

And you can use it as this:

// ES5
var fn = Y(function(fn) {
  return function(counter) {
    console.log(counter);
    if (counter > 0) {
      fn(counter - 1);
    }
  }
});

// ES6
const fn = Y(fn => counter => {
  console.log(counter);
  if (counter > 0) {
    fn(counter - 1);
  }
});

On modern Windows this driver isn't available by default anymore, but you can download as Microsoft Access Database Engine 2010 Redistributable on the MS site. If your app is 32 bits be sure to download and install the 32 bits variant because to my knowledge the 32 and 64 bit variant cannot coexist.

Depending on how your app locates its db driver, that might be all that's needed. However, if you use an UDL file there's one extra step - you need to edit that file. Unfortunately, on a 64bits machine the wizard used to edit UDL files is 64 bits by default, it won't see the JET driver and just slap whatever driver it finds first in the UDL file. There are 2 ways to solve this issue:

1. start the 32 bits UDL wizard like this: C:\Windows\syswow64\rundll32.exe "C:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll",OpenDSLFile C:\path\to\your.udl. Note that I could use this technique on a Win7 64 Pro, but it didn't work on a Server 2008R2 (could be my mistake, just mentioning)
2. open the UDL file in Notepad or another text editor, it should more or less have this format:

[oledb] ; Everything after this line is an OLE DB initstring Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\The\database.mdb;Persist Security Info=False

That should allow your app to start correctly.

You could listen to the 'keydown' event and then check for an enter key.

Your handler would be like:

function (e) {
  if (13 == e.keyCode) {
     ... do whatever ...
  }
}

finish();
 finishAffinity();
 System.exit(0);

worked for me

This problem usually happen if eclipse accidentally compile the main.xml incorrectly. The easiest solution is to delete R.java inside gen directory. Once we delete, than eclipse will generate the new R.java base on the latest main.xml

Sometimes the problem occurs because of the incorrect version of the project bytecode.

So verify it : File -> Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler -> Project bytecode version and set its value to 8

Mac OS X doesn't have apt-get. There is a package manager called Homebrew that is used instead.

This command would be:

brew install python

Use Homebrew to install packages that you would otherwise use apt-get for.

The page I linked to has an up-to-date way of installing homebrew, but at present, you can install Homebrew as follows:

Type the following in your Mac OS X terminal:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

After that, usage of Homebrew is brew install <package>.

One of the prerequisites for Homebrew are the XCode command line tools.

1. Install XCode from the App Store.
2. Follow the directions in this Stack Overflow answer to install the XCode Command Line Tools.

Background

A package manager (like apt-get or brew) just gives your system an easy and automated way to install packages or libraries. Different systems use different programs. apt and its derivatives are used on Debian based linux systems. Red Hat-ish Linux systems use rpm (or at least they did many, many, years ago). yum is also a package manager for RedHat based systems.

Alpine based systems use apk.

Warning

As of 25 April 2016, homebrew opts the user in to sending analytics by default. This can be opted out of in two ways:

Setting an environment variable:

1. Open your favorite environment variable editor.
2. Set the following: HOMEBREW_NO_ANALYTICS=1 in whereever you keep your environment variables (typically something like ~/.bash_profile)
3. Close the file, and either restart the terminal or source ~/.bash_profile.

Running the following command:

brew analytics off

the analytics status can then be checked with the command:

brew analytics

I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

You can try this

diff --changed-group-format='%>' --unchanged-group-format='' A1 A2

The options are documented in man diff:

       --GTYPE-group-format=GFMT
              format GTYPE input groups with GFMT

and:

       LTYPE is 'old', 'new', or 'unchanged'.
              GTYPE is LTYPE or 'changed'.

and:

              GFMT (only) may contain:

       %<     lines from FILE1

       %>     lines from FILE2

       [...]

Convert a String to ByteBuffer, then from ByteBuffer back to String using Java:

import java.nio.charset.Charset;
import java.nio.*;

String babel = "obufscate thdé alphebat and yolo!!";
System.out.println(babel);
//Convert string to ByteBuffer:
ByteBuffer babb = Charset.forName("UTF-8").encode(babel);
try{
    //Convert ByteBuffer to String
    System.out.println(new String(babb.array(), "UTF-8"));
}
catch(Exception e){
    e.printStackTrace();
}

Which prints the printed bare string first, and then the ByteBuffer casted to array():

obufscate thdé alphebat and yolo!!
obufscate thdé alphebat and yolo!!

Also this was helpful for me, reducing the string to primitive bytes can help inspect what's going on:

String text = "?????";
//convert utf8 text to a byte array
byte[] array = text.getBytes("UTF-8");
//convert the byte array back to a string as UTF-8
String s = new String(array, Charset.forName("UTF-8"));
System.out.println(s);
//forcing strings encoded as UTF-8 as an incorrect encoding like
//say ISO-8859-1 causes strange and undefined behavior
String sISO = new String(array, Charset.forName("ISO-8859-1"));
System.out.println(sISO);

Prints your string interpreted as UTF-8, and then again as ISO-8859-1:

?????

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

I have had the same error but b/c of diff reason. Using Entity framework. One more thing I need to add here before I share my code and solution, I had a break point on controller method but it was not breaking there, just throwing exception 500 internal server error.

I was posting data from view to controller through ajax (http post). The model I was expecting as a parameter was a class. It was inherited with some other class.

public class PurchaseOrder : CreateUpdateUserInfo
    {
        public PurchaseOrder()
        {
            this.Purchase_Order_Items = new List<clsItem>();
        }

        public int purchase_order_id { get; set; }
        public Nullable<int> purchase_quotation_id { get; set; }
        public int supplier_id { get; set; }
        public decimal flat_discount { get; set; }
        public decimal total { get; set; }
        public decimal net_payable { get; set; }
        public bool is_payment_complete { get; set; }
        public decimal sales_tax { get; set; }
        public DateTime CreatedOn { get; set; }
        public int CreatorUserID { get; set; }
        public DateTime UpdatedOn { get; set; }
        public int UpdatorUserID { get; set; }
        public bool IsDeleted { get; set; }
        public List<clsItem> Purchase_Order_Items { get; set; }
    }

 public class CreateUpdateUserInfo
    {
        public DateTime CreatedOn { get; set; }
        public int CreatorUserID { get; set; }
        public string CreatorUserName { get; set; }
        public DateTime UpdatedOn { get; set; }
        public int UpdatorUserID { get; set; }
        public string UpdatorUserName { get; set; }
        public bool IsDeleted { get; set; }
    }

and in view

                var model = {
                supplier_id : isNaN($scope.supplierID) || 0 ? null : $scope.supplierID,
                flat_discount : 0,
                total : $scope.total,
                net_payable :  $scope.total,
                is_payment_complete :  true,
                sales_tax:0,
                Purchase_Order_Item: $scope.items
            };
            var obj = {
                method: 'POST',
                url: 'Purchase/SaveOrder',
                dataType: 'json',
                data: JSON.stringify(model),
                headers: { "Content-Type": "application/json" }
            };

            var request = $rootScope.AjaxRequest(obj);
            request.then(function (response) {
                var isError = response.data.MessageType === 1;
                $rootScope.bindToaster(response.data.MessageType,response.data.Message);
                //$('html, body').animate({ scrollTop: 0 }, 'slow');
                if(!isError){
                    //$scope.supplierID =undefined;
                }
            }, function (response) {
                $rootScope.bindToaster(2,response.data);
                console.log(response);
            });

Simply removed duplicated fields from PurchaseOrder class and it worked like a charm.

The function input will also evaluate the data it just read as python code, which is not really what you want.

The generic approach would be to treat the user input (from sys.stdin) like any other file. Try

import sys
sys.stdin.readline()

If you want to keep it short, you can use raw_input which is the same as input but omits the evaluation.

exec has memory limitation of buffer size of 512k. In this case it is better to use spawn. With spawn one has access to stdout of executed command at run time

var spawn = require('child_process').spawn;
var prc = spawn('java',  ['-jar', '-Xmx512M', '-Dfile.encoding=utf8', 'script/importlistings.jar']);

//noinspection JSUnresolvedFunction
prc.stdout.setEncoding('utf8');
prc.stdout.on('data', function (data) {
    var str = data.toString()
    var lines = str.split(/(\r?\n)/g);
    console.log(lines.join(""));
});

prc.on('close', function (code) {
    console.log('process exit code ' + code);

array_slice returns a slice of an array

$sliced_array = array_slice($array, 0, 5)

add app:itemTextColor="#fff" in your NavigationView like

 <android.support.design.widget.NavigationView
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    app:menu="@menu/slider_menu"
    android:background="@color/colorAccent"
    app:itemTextColor="#fff"
    android:id="@+id/navigation_view"
    android:layout_gravity="start"/>

In collaboration with @drzaus we've come up with the following jQuery plugin.

jQuery.getSelector

!(function ($, undefined) {
    /// adapted http://jsfiddle.net/drzaus/Hgjfh/5/

    var get_selector = function (element) {
        var pieces = [];

        for (; element && element.tagName !== undefined; element = element.parentNode) {
            if (element.className) {
                var classes = element.className.split(' ');
                for (var i in classes) {
                    if (classes.hasOwnProperty(i) && classes[i]) {
                        pieces.unshift(classes[i]);
                        pieces.unshift('.');
                    }
                }
            }
            if (element.id && !/\s/.test(element.id)) {
                pieces.unshift(element.id);
                pieces.unshift('#');
            }
            pieces.unshift(element.tagName);
            pieces.unshift(' > ');
        }

        return pieces.slice(1).join('');
    };

    $.fn.getSelector = function (only_one) {
        if (true === only_one) {
            return get_selector(this[0]);

Observations:

• #include <cstring> should introduce std::strcpy().
• using namespace std; (as written in medico.h) introduces any identifiers from std:: into the global namespace.

Aside from using namespace std; being somewhat clumsy once the application grows larger (as it introduces one hell of a lot of identifiers into the global namespace), and that you should never use using in a header file (see below!), using namespace does not affect identifiers introduced after the statement.

(using namespace std is written in the header, which is included in medico.cpp, but #include <cstring> comes after that.)

My advice: Put the using namespace std; (if you insist on using it at all) into medico.cpp, after any includes, and use explicit std:: in medico.h.

strcmpi() is not a standard function at all; while being defined on Windows, you have to solve case-insensitive compares differently on Linux.

(On general terms, I would like to point to this answer with regards to "proper" string handling in C and C++ that takes Unicode into account, as every application should. Summary: The standard cannot handle these things correctly; do use ICU.)

warning: deprecated conversion from string constant to ‘char*’

A "string constant" is when you write a string literal (e.g. "Hello") in your code. Its type is const char[], i.e. array of constant characters (as you cannot change the characters). You can assign an array to a pointer, but assigning to char *, i.e. removing the const qualifier, generates the warning you are seeing.

OT clarification: using in a header file changes visibility of identifiers for anyone including that header, which is usually not what the user of your header file wants. For example, I could use std::string and a self-written ::string just perfectly in my code, unless I include your medico.h, because then the two classes will clash.

Don't use using in header files.

And even in implementation files, it can introduce lots of ambiguity. There is a case to be made to use explicit namespacing in implementation files as well.

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

(Already said) I found this out while making some Chrome themes (which are long gone now... :-P)

Chrome themes, extensions, etc. are just compressed files. Get 7-zip or WinRar to unzip it. Each extension/theme has a manifest.json file. Open the manifest.json file in notepad. Then, if you know the coding, modify the code. There will be some other files. If you look in the manifest file you might be able to figure out what the are for. Then, you can change everything...

I haven't any personal experience with either of the following, but a simple search for a "Python [memory] profiler" yield:

• PySizer, "a memory profiler for Python," found at http://pysizer.8325.org/. However the page seems to indicate that the project hasn't been updated for a while, and refers to...

• Heapy, "support[ing] debugging and optimization regarding memory related issues in Python programs," found at http://guppy-pe.sourceforge.net/#Heapy.

Hope that helps.

Try this - you need a CTE (Common Table Expression) that partitions (groups) your data by distinct e-mail address, and sorts each group by ID - smallest first. Then you just select the first entry for each group - that should give you what you're looking for:

;WITH DistinctMails AS
(
    SELECT ID, MailID, EMailAddress, NAME,
        ROW_NUMBER() OVER(PARTITION BY EMailAddress ORDER BY ID) AS 'RowNum'
    FROM dbo.YourMailTable
)
SELECT *
FROM DistinctMails
WHERE RowNum = 1

This works on SQL Server 2005 and newer (you didn't mention what version you're using...)

I am using a .Net Core 2.1 Web Application and could not get a single answer here to work. I either got a blank parameter (if the method was called at all) or a 500 server error. I started playing with every possible combination of answers and finally got a working result.

In my case the solution was as follows:

Script - stringify the original array (without using a named property)

    $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        url: mycontrolleraction,
        data: JSON.stringify(things)
    });

And in the controller method, use [FromBody]

    [HttpPost]
    public IActionResult NewBranch([FromBody]IEnumerable<Thing> things)
    {
        return Ok();
    }

Failures include:

• Naming the content

  data: { content: nodes }, // Server error 500

• Not having the contentType = Server error 500

Notes

• dataType is not needed, despite what some answers say, as that is used for the response decoding (so not relevant to the request examples here).
• List<Thing> also works in the controller method

for example you can return list of all tables in database to the all views of Controller like this :

public function __construct()
{
    $tables = DB::select('SHOW TABLES'); // returns an array of stdObjects
    view()->share('tables', $tables);
}

A char represents a character in Java ^(*). It is 2 bytes large (at least that's what the valid value range suggests).

That doesn't necessarily mean that every representation of a character is 2 bytes long. In fact many encodings only reserve 1 byte for every character (or use 1 byte for the most common characters).

When you call the String(byte[]) constructor you ask Java to convert the byte[] to a String using the platform default encoding. Since the platform default encoding is usually a 1-byte encoding such as ISO-8859-1 or a variable-length encoding such as UTF-8, it can easily convert that 1 byte to a single character.

If you run that code on a platform that uses UTF-16 (or UTF-32 or UCS-2 or UCS-4 or ...) as the platform default encoding, then you will not get a valid result (you'll get a String containing the Unicode Replacement Character instead).

That's one of the reasons why you should not depend on the platform default encoding: when converting between byte[] and char[]/String or between InputStream and Reader or between OutputStream and Writer, you should always specify which encoding you want to use. If you don't, then your code will be platform-dependent.

^{(*) that's not entirely true: a char represents a UTF-16 codepoint. Either one or two UTF-16 codepoints represent a Unicode codepoint. A Unicode codepoint usually represents a character, but sometimes multiple Unicode codepoints are used to make up a single character. But the approximation above is close enough to discuss the topic at hand.}

Because C will promote floats to doubles for functions that take variable arguments. Pointers aren't promoted to anything, so you should be using %lf, %lg or %le (or %la in C99) to read in doubles.

Working in bash 4 or higher version:

#!/bin/bash
echo "$0";         #"bash"
bash --version;    #"GNU bash, version 5.0.3(1)-release (x86_64-pc-linux-gnu)"

In function:

echo $@;              #"p1" "p2" "p3" "p4" "p5"
echo ${@: 0};  #"bash" "p1" "p2" "p3" "p4" "p5"
echo ${@: 1};         #"p1" "p2" "p3" "p4" "p5"
echo ${@: 2};              #"p2" "p3" "p4" "p5"
echo ${@: 2:1};            #"p2"
echo ${@: 2:2};            #"p2" "p3"
echo ${@: -2};                       #"p4" "p5"
echo ${@: -2:1};                     #"p4"

Notice the space between ':' and '-', otherwise it means different:

${var:-word} If var is null or unset,
word is substituted for var. The value of var does not change.

${var:+word} If var is set,
word is substituted for var. The value of var does not change.

Which is described in:Unix / Linux - Shell Substitution

if you want to extract the contents of an already-loaded UIWebView, -stringByEvaluatingJavaScriptFromString. For example:

NSString  *html = [webView stringByEvaluatingJavaScriptFromString: @"document.body.innerHTML"];

Using $resource in AngularJS you can do:

task.service.js

$ngTask.factory("$taskService", [
    "$resource",
    function ($resource) {
        var taskModelUrl = 'api/task/';
        return {
            rest: {
                taskUpload: $resource(taskModelUrl, {
                    id: '@id'
                }, {
                    save: {
                        method: "POST",
                        isArray: false,
                        headers: {"Content-Type": undefined},
                        transformRequest: angular.identity
                    }
                })
            }
        };
    }
]);

And then use it in a module:

task.module.js

$ngModelTask.controller("taskController", [
    "$scope",
    "$taskService",
    function (
        $scope,
        $taskService,
    ) {
    $scope.saveTask = function (name, file) {
        var newTask,
            payload = new FormData();
        payload.append("name", name);
        payload.append("file", file);
        newTask = $taskService.rest.taskUpload.save(payload);
        // check if exists
    }
}

Below are the differences between CrudRepository and JpaRepository as:

CrudRepository

1. CrudRepository is a base interface and extends the Repository interface.
2. CrudRepository mainly provides CRUD (Create, Read, Update, Delete) operations.
3. Return type of saveAll() method is Iterable.
4. Use Case - To perform CRUD operations, define repository extending CrudRepository.

JpaRepository

1. JpaRepository extends PagingAndSortingRepository that extends CrudRepository.
2. JpaRepository provides CRUD and pagination operations, along with additional methods like flush(), saveAndFlush(), and deleteInBatch(), etc.
3. Return type of saveAll() method is a List.
4. Use Case - To perform CRUD as well as batch operations, define repository extends JpaRepository.

My 2 cents: Compile against any version of the SDK but take care not to call any APIs that your "minimum SDK version" does not support. That means you "could" compile against the latest version of the SDK.

As for "target version" it simply refers to what you planned to target in the first place and have possibly tested against. If you haven't done the due diligence then this is the way to inform Android that it needs to perform some additional checks before it deploys your lets say "Lollipop" targeted app on "Oreo".

So the "target version" is obviously not lower than your "minimum SDK version" but it can't be higher than your "compiled version".

As long as your selector is actually working, I see nothing wrong with your code that checks the length of the array. That should do what you want. There are a lot of ways to clean up your code to be simpler and more readable. Here's a cleaned up version with notes about what I cleaned up.

var album_text = [];

$("input[name='album_text[]']").each(function() {
    var value = $(this).val();
    if (value) {
        album_text.push(value);
    }
});
if (album_text.length === 0) {
    $('#error_message').html("Error");
}

else {
  //send data
}

Some notes on what you were doing and what I changed.

1. $(this) is always a valid jQuery object so there's no reason to ever check if ($(this)). It may not have any DOM objects inside it, but you can check that with $(this).length if you need to, but that is not necessary here because the .each() loop wouldn't run if there were no items so $(this) inside your .each() loop will always be something.
2. It's inefficient to use $(this) multiple times in the same function. Much better to get it once into a local variable and then use it from that local variable.
3. It's recommended to initialize arrays with [] rather than new Array().
4. if (value) when value is expected to be a string will both protect from value == null, value == undefined and value == "" so you don't have to do if (value && (value != "")). You can just do: if (value) to check for all three empty conditions.
5. if (album_text.length === 0) will tell you if the array is empty as long as it is a valid, initialized array (which it is here).

What are you trying to do with this selector $("input[name='album_text[]']")?

It is possible to use Ghostscript to read PDF files and print them to a named printer.

To anybody coming to this thread after hours of banging your head against a wall. I solved this error by changing

create table `group`(
    id char(19) primary key
);

to

create table if not exists `group`(
    id char(19) primary key
);

in my schema.sql file in the resources directory.

As other people have commented above, using TRUNC will prevent the use of indexes (if there was an index on TIME_CREATED). To avoid that problem, the query can be structured as

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TIME_CREATED BETWEEN TO_DATE('26/JAN/2011','dd/mon/yyyy') 
            AND TO_DATE('26/JAN/2011','dd/mon/yyyy') + INTERVAL '86399' second;

86399 being 1 second less than the number of seconds in a day.

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

def filter_out_colors(elements):
  colors = ['red', 'green']
  result = []
  for element in elements:
    if element in colors:
       continue # skip the element
    # You can do whatever here
    result.append(element)
  return result

  >>> filter_out_colors(['lemon', 'orange', 'red', 'pear'])
  ['lemon', 'orange', 'pear']

I also added

.modal { position: absolute; }

to the stylesheet to allow the dialog to scroll, but if the user has moved down to the bottom of a long page the modal can end up hidden off the top of the visible area.

I understand this is no longer an issue in bootstrap 3, but looking for a relatively quick fix until we upgrade I ended up with the above plus calling the following before opening the modal

$('.modal').css('top', $(document).scrollTop() + 50);

Seems to be happy in FireFox, Chrome, IE10 8 & 7 (the browsers I had to hand)

The way of dknaack does not work for me, I found this solution as well:

@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList, 
                    "Select chapter", new { @onchange = "location = this.value;" })

where

@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)

In the controller you can add:

DbModel db = new DbModel();    //entity model of Entity Framework

ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       <whatever>
   else:
       raise

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

In SQL Server , cast text as datetime

Firstly, you should read this page thoroughly http://codex.wordpress.org/AJAX_in_Plugins

Secondly, ajax_script is not defined so you should change to: url: ajaxurl. I don't see your function1() in the above code but you might already define it in other file.

And finally, learn how to debug ajax call using Firebug, network and console tab will be your friends. On the PHP side, print_r() or var_dump() will be your friends.

1) Using native php filters, I've got the following result :

The children property returns an array of elements, like so:

parent = document.querySelector('.parent');
children = parent.children; // [<div class="child1">]

There are alternatives to querySelector, like document.getElementsByClassName('parent')[0] if you so desire.

Edit: Now that I think about it, you could just use querySelectorAll to get decendents of parent having a class name of child1:

children = document.querySelectorAll('.parent .child1');

The difference between qS and qSA is that the latter returns all elements matching the selector, while the former only returns the first such element.

If using reactive forms, you can also disable the entire form or any sub-set of controls in a FormGroup with myFormGroup.disable().

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Jsfiddle

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

In C++, consider the State pattern.

For all who are interested in a swift extension, this is what I'm using now:

extension UINavigationController {
    var rootViewController : UIViewController? {
        return self.viewControllers.first
    }
}

A mutable variable is one whose value may change in place, whereas in an immutable variable change of value will not happen in place. Modifying an immutable variable will rebuild the same variable.

It is as simple as this query shown below.

UPDATE 
  Table1 T1 join Table2 T2 on T1.id = T2.id
SET 
  T1.LastName='DR. XXXXXX', 
  T2.WAprrs='start,stop'

For creating real UML class diagrams:

In Visual Studio 2013 Ultimate you can do this without any external tools.

• In the menu, click on Architecture, New Diagram Select UML Class Diagram
• This will ask you to create a new Modeling Project if you don't have one already.

You will have a empty UMLClassDiagram.classdiagram.

• Again, go to Architecture, Windows, Architecture Explorer.
• A window will pop up with your namespaces, Choose Class View.
• Then a list of sub-namespaces will appear, if any. Choose one, select the classes and drag them to the empty UMLClassDiagram1.classdiagram window.

I have stumbled upon this problem for one hour. After an hour, I tried debugging and this helped:

$('.list').on('click', 'span', (e) => {
  $(e.target).parent().remove();
});

HTML:

<ul class="list">
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
</ul>

Instance variable is the variable declared inside a class, but outside a method: something like:

class IronMan {

    /** These are all instance variables **/
    public String realName;
    public String[] superPowers;
    public int age;

    /** Getters and setters here **/
}

Now this IronMan Class can be instantiated in another class to use these variables. Something like:

class Avengers {

    public static void main(String[] a) {
        IronMan ironman = new IronMan();
        ironman.realName = "Tony Stark";
        // or
        ironman.setAge(30);
    }

}

This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.

window.addEventListener("scroll", function(evt) {
    var pos_top = document.body.scrollTop;   
    if(pos_top == 0){
       $('#divID').css('position','fixed');
    }

    else if(pos_top > 0){
       $('#divId').css('position','static');
    }
});

You can do this by following one of the solutions:

Using constructor @Autowired

This approach will construct the bean requiring some beans as constructor parameters. Within the constructor code you set the static field with the value got as parameter for constructor execution. Sample:

@Component
public class Boo {

    private static Foo foo;

    @Autowired
    public Boo(Foo foo) {
        Boo.foo = foo;
    }

    public static void randomMethod() {
         foo.doStuff();
    }
}

Using @PostConstruct to hand value over to static field

The idea here is to hand over a bean to a static field after bean is configured by spring.

@Component
public class Boo {

    private static Foo foo;
    @Autowired
    private Foo tFoo;

    @PostConstruct
    public void init() {
        Boo.foo = tFoo;
    }

    public static void randomMethod() {
         foo.doStuff();
    }
}

Here is my rendition....

function get_time_difference(earlierDate, laterDate) 
{
    var oDiff = new Object();

    //  Calculate Differences
    //  -------------------------------------------------------------------  //
    var nTotalDiff = laterDate.getTime() - earlierDate.getTime();

    oDiff.days = Math.floor(nTotalDiff / 1000 / 60 / 60 / 24);
    nTotalDiff -= oDiff.days * 1000 * 60 * 60 * 24;

    oDiff.hours = Math.floor(nTotalDiff / 1000 / 60 / 60);
    nTotalDiff -= oDiff.hours * 1000 * 60 * 60;

    oDiff.minutes = Math.floor(nTotalDiff / 1000 / 60);
    nTotalDiff -= oDiff.minutes * 1000 * 60;

    oDiff.seconds = Math.floor(nTotalDiff / 1000);
    //  -------------------------------------------------------------------  //

    //  Format Duration
    //  -------------------------------------------------------------------  //
    //  Format Hours
    var hourtext = '00';
    if (oDiff.days > 0){ hourtext = String(oDiff.days);}
    if (hourtext.length == 1){hourtext = '0' + hourtext};

    //  Format Minutes
    var mintext = '00';
    if (oDiff.minutes > 0){ mintext = String(oDiff.minutes);}
    if (mintext.length == 1) { mintext = '0' + mintext };

    //  Format Seconds
    var sectext = '00';
    if (oDiff.seconds > 0) { sectext = String(oDiff.seconds); }
    if (sectext.length == 1) { sectext = '0' + sectext };

    //  Set Duration
    var sDuration = hourtext + ':' + mintext + ':' + sectext;
    oDiff.duration = sDuration;
    //  -------------------------------------------------------------------  //

    return oDiff;
}

You can use the File constructor:

var file = new File([myBlob], "name");

As per the w3 specification this will append the bytes that the blob contains to the bytes for the new File object, and create the file with the specified name http://www.w3.org/TR/FileAPI/#dfn-file

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

Just add the name of the table between DELETE and FROM from where you want to delete records, because we have to specify the table to delete. Also remove the ORDER BY clause because there is nothing to order while deleting records.

So your final query should be like this:

    DELETE WorkRecord2 
      FROM WorkRecord2 
INNER JOIN Employee 
        ON EmployeeRun=EmployeeNo
     WHERE Company = '1' 
       AND Date = '2013-05-06';

Another option is to run ng serve command with the --port option e.g

ng serve --port 5050 (i.e for port 5050)

Alternatively, the command: ng serve --port 0, will auto assign an available port for use.

I got this problem using Git Bash on Windows. I run npm start, or node app.js. After terminating it with Ctrl+C shortly and trying to start the server again using npm start or node app.js then I get this error message.

When I do this with the regular Windows Command Prompt, however, it works fine.

Or You can do it in another way. Open the Task Manager and Find the "Node.js:Server-side JavaScript" row. Select that and end task. It should work now.

Thanks.

Calling a RESTful API using RestTemplate

Example 1:

RestTemplate restTemplate = new RestTemplate();
// Add the Jackson message converter
restTemplate.getMessageConverters()
                .add(new MappingJackson2HttpMessageConverter());
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Basic XXXXXXXXXXXXXXXX=");
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
restTemplate.getInterceptors()
                .add(new BasicAuthorizationInterceptor(USERID, PWORD));
String requestJson = getRequetJson(Code, emailAddr, firstName, lastName);
response = restTemplate.postForObject(URL, requestJson, MYObject.class);
        

Example 2:

RestTemplate restTemplate = new RestTemplate();
String requestJson = getRequetJson(code, emil, name, lastName);
HttpHeaders headers = new HttpHeaders();
String userPass = USERID + ":" + PWORD;
String authHeader =
    "Basic " + Base64.getEncoder().encodeToString(userPass.getBytes());
headers.set(HttpHeaders.AUTHORIZATION, authHeader);
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
HttpEntity<String> request = new HttpEntity<String>(requestJson, headers);
ResponseEntity<MyObject> responseEntity;
responseEntity =
    this.restTemplate.exchange(URI, HttpMethod.POST, request, Object.class);
responseEntity.getBody()

The getRequestJson method creates a JSON Object:

private String getRequetJson(String Code, String emailAddr, String name) {
    ObjectMapper mapper = new ObjectMapper();
    JsonNode rootNode = mapper.createObjectNode();
    ((ObjectNode) rootNode).put("code", Code);
    ((ObjectNode) rootNode).put("email", emailAdd);
    ((ObjectNode) rootNode).put("firstName", name);
    String jsonString = null;
    try {
        jsonString = mapper.writerWithDefaultPrettyPrinter()
                               .writeValueAsString(rootNode);
    }
    catch (JsonProcessingException e) {
        e.printStackTrace();
    }
    return jsonString;
}

I would recommend using WordPress custom fields to store eligible postcodes for each product. add_post_meta() and update_post_meta are what you're looking for. It's not recommended to alter the default WordPress table structure. All postmetas are inserted in wp_postmeta table. You can find the corresponding products within wp_posts table.

char string[something];
sprintf(string, "%d", 42);

You can try returning the variable you wish to inspect. E.g. I have this function:

--Contencates seperate date and time strings and converts to a datetime. Date should be in format 25.03.2012. Time as 9:18:25.
ALTER FUNCTION [dbo].[ufn_GetDateTime] (@date nvarchar(11), @time nvarchar(11))
RETURNS datetime
AS
BEGIN

        --select dbo.ufn_GetDateTime('25.03.2012.', '9:18:25')

    declare @datetime datetime

    declare @day_part nvarchar(3)
    declare @month_part nvarchar(3)
    declare @year_part nvarchar(5)

    declare @point_ix int

    set @point_ix = charindex('.', @date)
    set @day_part = substring(@date, 0, @point_ix)

    set @date = substring(@date, @point_ix, len(@date) - @point_ix)
    set @point_ix = charindex('.', @date)

    set @month_part = substring(@date, 0, @point_ix)

    set @date = substring(@date, @point_ix, len(@date) - @point_ix)
    set @point_ix = charindex('.', @date)

    set @year_part = substring(@date, 0, @point_ix)

    set @datetime = @month_part + @day_part  + @year_part + ' ' + @time

    return @datetime
END

When I run it.. I get: Msg 241, Level 16, State 1, Line 1 Conversion failed when converting date and/or time from character string.

Arghh!!

So, what do I do?

ALTER FUNCTION [dbo].[ufn_GetDateTime] (@date nvarchar(11), @time nvarchar(11))
RETURNS nvarchar(22)
AS
BEGIN

        --select dbo.ufn_GetDateTime('25.03.2012.', '9:18:25')

    declare @day_part nvarchar(3)
    declare @point_ix int

    set @point_ix = charindex('.', @date)
    set @day_part = substring(@date, 0, @point_ix)

    return @day_part
END

And I get '25'. So, I am off by one and so I change to..

set @day_part = substring(@date, 0, @point_ix + 1)

Voila! Now it works :)

Nope, this is not possible at all. There is no provision for it in the mailto: protocol, and it would be a gaping security hole if it were possible.

The best idea to send a file, but have the client send the E-Mail that I can think of is:

• Have the user choose a file
• Upload the file to a server
• Have the server return a random file name after upload
• Build a mailto: link that contains the URL to the uploaded file in the message body

In R the equivalent function is seq and you can use it with the option by:

seq(from = 5, to = 100, by = 5)
# [1]   5  10  15  20  25  30  35  40  45  50  55  60  65  70  75  80  85  90  95 100

In addition to by you can also have other options such as length.out and along.with.

length.out: If you want to get a total of 10 numbers between 0 and 1, for example:

seq(0, 1, length.out = 10)
# gives 10 equally spaced numbers from 0 to 1

along.with: It takes the length of the vector you supply as input and provides a vector from 1:length(input).

seq(along.with=c(10,20,30))
# [1] 1 2 3

Although, instead of using the along.with option, it is recommended to use seq_along in this case. From the documentation for ?seq

seq is generic, and only the default method is described here. Note that it dispatches on the class of the first argument irrespective of argument names. This can have unintended consequences if it is called with just one argument intending this to be taken as along.with: it is much better to use seq_along in that case.

seq_along: Instead of seq(along.with(.))

seq_along(c(10,20,30))
# [1] 1 2 3

Hope this helps.

One way you can do this, is to Keep track of the current selected position in your activity:

@Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position,
            long arg3) {
        currentPosition = position
        lv_cli.notifyDataSetChanged();
    }

Now, be sure you assign an ID to the parent layout (linearLayout, boxLayout, relativeLayout, .. Whatever you prefer) of your list item.

Then in your ListView you can do something Like this:

layoutBackground = (LinearLayout) convertView.findViewById(R.id.layout_background);

if (YourActivity.this.currentPosition == position) {
    layoutBackground.setBackgroundColor(YourActivity.this.getResources().getColor(R.color.hilight_color));
} else{
    layoutBackground.setBackgroundResource(R.drawable.list_item_drawable);
}

Basically, you just set the hilight color to the layout as a background when it equals your current selected position. Notice how I set a drawable background resource when the item is not selected. This could be in your case different (since you posted no code). In my case, this drawable is a selector which makes sure the item is hi-lighted when pressed.

NOTE: This simple code doesn't use a view-holder, but I really recommend using one.

As per my current condition, I follow this approach. I want to give identity to a primary table after data inserted via script.

As I want to append identity, so it always start from 1 to End of record count that I want.

--first drop column and add with identity
ALTER TABLE dbo.tblProductPriceList drop column ID 
ALTER TABLE dbo.tblProductPriceList add ID INT IDENTITY(1,1)

--then add primary key to that column (exist option you can ignore)
IF  NOT EXISTS (SELECT * FROM sys.key_constraints  WHERE object_id = OBJECT_ID(N'[dbo].[PK_tblProductPriceList]') AND parent_object_id = OBJECT_ID(N'[dbo].[tblProductPriceList]'))
    ALTER TABLE [tblProductPriceList] ADD PRIMARY KEY (id)
GO

This will create the same primary key column with identity

I used this links : https://blog.sqlauthority.com/2014/10/11/sql-server-add-auto-incremental-identity-column-to-table-after-creating-table/

Add primary key to existing table

In addition to using jQuery methods, you can use the native cells collection that the <tr> gives you.

$(t)[0].cells[1].innerHTML

Assuming t is a DOM element, you could bypass the jQuery object creation.

t.cells[1].innerHTML

1. Unique
2. cluster
3. non-cluster
4. column store
5. Index with included column
6. index on computed column
7. filtered
8. spatial
9. xml
10. full text

I'm assuming that id is supposed to be an incrementing value.

You need to set this, or else if you have a non-nullable column, with no default value, if you provide no value it will error.

To set up auto-increment in SQL Server Management Studio:

• Open your table in Design
• Select your column and go to Column Properties
• Under Indentity Specification, set (Is Identity)=Yes and Indentity Increment=1

This is the most concise way I have found, provided the destination is empty. Switch to an empty folder and then:

# Note the period for cwd >>>>>>>>>>>>>>>>>>>>>>>> v
git clone --bare https://your-source-repo/repo.git .
git push --mirror https://your-destination-repo/repo.git

Substitute https://... for file:///your/repo etc. as appropriate.

First check your imports, when you use session, transaction it should be org.hibernate and remove @Transactinal annotation. and most important in Entity class if you have used @GeneratedValue(strategy=GenerationType.AUTO) or any other then at the time of model object creation/entity object creation should not create id. final conclusion is if you want pass id filed i.e PK then remove @GeneratedValue from entity class.

r = list(qs[:1])
if r:
  return r[0]
return None

You are printing the wrong value. Instead if the string you print the scanners object. Try this

Scanner input = new Scanner(System.in);
String s = input.next();
System.out.println(s);

The best method I know of is to use a Perceptual Hash. There appears to be a good open source implementation of such a hash available at:

http://phash.org/

The main idea is that each image is reduced down to a small hash code or 'fingerprint' by identifying salient features in the original image file and hashing a compact representation of those features (rather than hashing the image data directly). This means that the false positives rate is much reduced over a simplistic approach such as reducing images down to a tiny thumbprint sized image and comparing thumbprints.

phash offers several types of hash and can be used for images, audio or video.

Sessions would be the only good way, you could also use GET/POST but that would be potentially insecure.

For positives, try

int(x + 0.5)

To make it work for negatives too, try

int(x + (0.5 if x > 0 else -0.5))

int() works like a floor function and hence you can exploit this property. This is definitely the fastest way.

If you use package osext by kardianos and you need to test locally, like Derek Dowling commented:

This works fine until you'd like to use it with go run main.go for local development. Not sure how best to get around that without building an executable beforehand each time.

The solution to this is to make a gorun.exe utility instead of using go run. The gorun.exe utility would compile the project using "go build", then run it right after, in the normal directory of your project.

I had this issue with other compilers and found myself making these utilities since they are not shipped with the compiler... it is especially arcane with tools like C where you have to compile and link and then run it (too much work).

If anyone likes my idea of gorun.exe (or elf) I will likely upload it to github soon..

Sorry, this answer is meant as a comment, but I cannot comment due to me not having a reputation big enough yet.

Alternatively, "go run" could be modified (if it does not have this feature already) to have a parameter such as "go run -notemp" to not run the program in a temporary directory (or something similar). But I would prefer just typing out gorun or "gor" as it is shorter than a convoluted parameter. Gorun.exe or gor.exe would need to be installed in the same directory as your go compiler

Implementing gorun.exe (or gor.exe) would be trivial, as I have done it with other compilers in only a few lines of code... (famous last words ;-)

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.

# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12

# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert

To verify the contents of the JKS, you can use this command:

keytool -list -v -keystore mykeystore.jks

If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.

You can use bringToFront:

    View view=findViewById(R.id.btnStartGame);
    view.bringToFront();

• These methods are performance-engineered (they integrate with operating system native I/O).

                 java.nio.file.LinkOption.NOFOLLOW_LINKS);

Moving a directory or file

long bytes = java.nio.file.Files.move( 
                 new java.io.File("<filepath1>").toPath(), 
                 new java.io.File("<filepath2>").toPath(),

I think It's a best approach to use Apache lang dependency to decide which OS you're running programmatically through Java

import org.apache.commons.lang3.SystemUtils;

public class App {
    public static void main( String[] args ) {
        if(SystemUtils.IS_OS_WINDOWS_7)
            System.out.println("It's a Windows 7 OS");
        if(SystemUtils.IS_OS_WINDOWS_8)
            System.out.println("It's a Windows 8 OS");
        if(SystemUtils.IS_OS_LINUX)
            System.out.println("It's a Linux OS");
        if(SystemUtils.IS_OS_MAC)
            System.out.println("It's a MAC OS");
    }
}

I tried to get this working using FINDSTR, but for some reason my "debugging" command always output an error level of 0:

ECHO %ERRORLEVEL%

My workaround is to use Grep from Cygwin, which outputs the right errorlevel (it will give an errorlevel greater than 0) if a string is not found:

dir c:\*.tib >out 2>>&1
grep "1 File(s)" out
IF %ERRORLEVEL% NEQ 0 "Run other commands" ELSE "Run Errorlevel 0 commands"

Cygwin's grep will also output errorlevel 2 if the file is not found. Here's the hash from my version:

C:\temp\temp>grep --version grep (GNU grep) 2.4.2

C:\cygwin64\bin>md5sum grep.exe c0a50e9c731955628ab66235d10cea23 *grep.exe

C:\cygwin64\bin>sha1sum grep.exe ff43a335bbec71cfe99ce8d5cb4e7c1ecdb3db5c *grep.exe

Make it like this:

$scope.users.data.length;

If you're just testing your APIs manually, we've found RestClient 2.3 or the Poster add-on for Firefox to be pretty helpful. Both of these let you build requests that GET, PUT, POST, or DELETE. You can save these requests to rerun later.

For simple automated testing try the Linux (or Cygwin) 'curl' command in a shell script.

From something more industrial strength you can move up to Apache JMeter. JMeter is great for load testing.

I wrote a very simple class for exporting to "Excel XML" aka SpreadsheetML. It's not quite as convenient for the end user as XSLX (depending on file extension and Excel version, they may get a warning message), but it's a lot easier to work with than XLS or XLSX.

sort() was deprecated for DataFrames in favor of either:

• sort_values() to sort by column(s)
• sort_index() to sort by the index

sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).

Add this on to the end of it:

var array = $("#hidAll").html();

x = array.split(',');
key=s="";
for (i=0; i<x.length; i++) {
  oldkey = key;
  key = x[i].split('|')[0];
  if (oldkey==key) s+='!';
  else s+=',\n'+key+'|';
  s+=x[i].split('|')[1];
}
s = s.substring(1);
$('#hidAll').html(a);

I'm using Visual Studio Professional licensed over the MAPS Action Pack subscription. Since the new version of the Microsoft Partner Center one have to add the subscribed user to the partner benefit software.

see 4. Place the columns side by side special

To make the two columns (#main and #sidebar) display side by side we float them, one to the left and the other to the right. We also specify the widths of the columns.

    #main {
    float:left;
    width:500px;
    background:#9c9;
    }
    #sidebar {
    float:right;
    width:250px;
   background:#c9c;
   }

Note that the sum of the widths should be equal to the width given to #wrap in Step 3.

Maybe this could be a little older article. but must of the above answers don´t help me as I need. Then I wrote a little snippet for that.

This accepts any XML that hast at least 3 levels (Like this sample):

<XmlData>
    <XmlRow>
        <XmlField1>Data 1</XmlField1>  
        <XmlField2>Data 2</XmlField2>  
        <XmlField3>Data 3</XmlField3>  
        .......
    </XmlRow>
</XmlData>

public static class XmlParser
{
    /// <summary>
    /// Converts XML string to DataTable
    /// </summary>
    /// <param name="Name">DataTable name</param>
    /// <param name="XMLString">XML string</param>
    /// <returns></returns>
    public static DataTable BuildDataTableFromXml(string Name, string XMLString)
    {
        XmlDocument doc = new XmlDocument();
        doc.Load(new StringReader(XMLString));
        DataTable Dt = new DataTable(Name);
        try
        {

            XmlNode NodoEstructura = doc.FirstChild.FirstChild;
            //  Table structure (columns definition) 
            foreach (XmlNode columna in NodoEstructura.ChildNodes)
            {
                Dt.Columns.Add(columna.Name, typeof(String));
            }

            XmlNode Filas = doc.FirstChild;
            //  Data Rows 
            foreach (XmlNode Fila in Filas.ChildNodes)
            {
                List<string> Valores = new List<string>();
                foreach (XmlNode Columna in Fila.ChildNodes)
                {
                    Valores.Add(Columna.InnerText);
                }
                Dt.Rows.Add(Valores.ToArray());
            }
        } catch(Exception)
        {

        }

        return Dt;
    }
}

This solve my problem

Getting width is easy but height can be tricky, following are the ways to deal with height

// Full screen width and height
double width = MediaQuery.of(context).size.width;
double height = MediaQuery.of(context).size.height;

// Height (without SafeArea)
var padding = MediaQuery.of(context).padding;
double height1 = height - padding.top - padding.bottom;

// Height (without status bar)
double height2 = height - padding.top;

// Height (without status and toolbar)
double height3 = height - padding.top - kToolbarHeight;

i always use connection.relase(); after pool.getconnetion like

pool.getConnection(function (err, connection) {
      connection.release();
        if (!err)
        {
            console.log('*** Mysql Connection established with ', config.database, ' and connected as id ' + connection.threadId);
            //CHECKING USERNAME EXISTENCE
            email = receivedValues.email
            connection.query('SELECT * FROM users WHERE email = ?', [email],
                function (err, rows) {
                    if (!err)
                    {
                        if (rows.length == 1)
                        {
                            if (bcrypt.compareSync(req.body.password, rows[0].password))
                            {
                                var alldata = rows;
                                var userid = rows[0].id;
                                var tokendata = (receivedValues, userid);
                                var token = jwt.sign(receivedValues, config.secret, {
                                    expiresIn: 1440 * 60 * 30 // expires in 1440 minutes
                                });

You can always do

git clone git://repo.org/fossproject.git && rm -rf fossproject/.git

Use fragments from Support Library -

android.support.v4.app.Fragment

and then override

void onAttach (Context context) {
  this.context = context;
}

This way you can be sure that context will always be a non-null value.

Add this to your web config and change the catalog name which is your database name:

  <connectionStrings>
    <add name="MyConnectionString" connectionString="Data Source=SERGIO-DESKTOP\SQLEXPRESS;Initial Catalog=YourDatabaseName;Integrated Security=True;"/></connectionStrings>

Reference System.Configuration assembly in your project.

Here is how you retrieve connection string from the config file:

System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

json might not be the best choice for on-disk formats; The trouble it has with appending data is a good example of why this might be. Specifically, json objects have a syntax that means the whole object must be read and parsed in order to understand any part of it.

Fortunately, there are lots of other options. A particularly simple one is CSV; which is supported well by python's standard library. The biggest downside is that it only works well for text; it requires additional action on the part of the programmer to convert the values to numbers or other formats, if needed.

Another option which does not have this limitation is to use a sqlite database, which also has built-in support in python. This would probably be a bigger departure from the code you already have, but it more naturally supports the 'modify a little bit' model you are apparently trying to build.

timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(createEnemy), userInfo: nil, repeats: true)

And Create Fun By The Name createEnemy

fund createEnemy ()
{
do anything ////
}

I found myself in a similar predicament today while trying to run a command through a Node.js module:

I was using the PowerShell and trying to run:

command -e 'func($a)'

But with the extra symbols, PowerShell was mangling the arguments. To fix, I back-tick escaped double-quote marks:

command -e `"func($a)`"

You can use placeholders and feed_dict.

Suppose we have numpy arrays like these:

trX = np.linspace(-1, 1, 101) 
trY = 2 * trX + np.random.randn(*trX.shape) * 0.33 

You can declare two placeholders:

X = tf.placeholder("float") 
Y = tf.placeholder("float")

Then, use these placeholders (X, and Y) in your model, cost, etc.: model = tf.mul(X, w) ... Y ... ...

Finally, when you run the model/cost, feed the numpy arrays using feed_dict:

with tf.Session() as sess:
.... 
    sess.run(model, feed_dict={X: trY, Y: trY})

If you need to use multiple dialog boxes on one page and open, close and reopen them the following works well:

 JS CODE:
    $(".sectionHelp").click(function(){
        $("#dialog_"+$(this).attr('id')).dialog({autoOpen: false});
        $("#dialog_"+$(this).attr('id')).dialog("open");
    });

 HTML: 
    <div class="dialog" id="dialog_help1" title="Dialog Title 1">
        <p>Dialog 1</p>
    </div>
    <div class="dialog" id="dialog_help2" title="Dialog Title 2">
        <p>Dialog 2 </p>
    </div>

    <a href="#" id="help1" class="sectionHelp"></a>
    <a href="#" id="help2" class="sectionHelp"></a>

 CSS:
    div.dialog{
      display:none;
    }

If you are using asset catalog, and have multiple targets both using same asset catalog file, be sure that this file has checked both targets in the right panel in xcode.

That was my problem.
