Programs & Examples On #Import

C:\xampp\mysql\bin>mysql -u {DB_USER} -p {DB_NAME} < path/to/file/filename.sql

mysql -u root -p dbname< "C:\Users\sdkca\Desktop\mydb.sql"

I am an experienced programmer, but, quite new into Go world ! And I confess I've faced few difficulties to understand Go... I faced this same problem when trying to organize my go files in sub-folders. The way I did it :

GO_Directory ( the one assigned to $GOPATH )

GO_Directory //the one assigned to $GOPATH
__MyProject
_____ main.go
_____ Entites
_____ Fiboo // in my case, fiboo is a database name
_________ Client.go // in my case, Client is a table name

On File MyProject\Entities\Fiboo\Client.go

package Fiboo

type Client struct{
    ID int
    name string
}

on file MyProject\main.go

package main

import(
    Fiboo "./Entity/Fiboo" 
)

var TableClient  Fiboo.Client

func main(){
    TableClient.ID = 1
    TableClient.name = 'Hugo'

    // do your things here
}

( I am running Go 1.9 on Ubuntu 16.04 )

And remember guys, I am newbie on Go. If what I am doing is bad practice, let me know !

but what I got is something like this: Date@124bbbf  
while I change the import to: import java.util.Date;  
the code works perfectly, why? 

What do you mean by "works perfectly"? The output of printing a Date object is the same no matter whether you imported java.util.* or java.util.Date. The output that you get when printing objects is the representation of the object by the toString() method of the corresponding class.

Does your DLL project have any actual exports? If there are no exports, the linker will not generate an import library .lib file.

In the non-Express version of VS, the import libray name is specfied in the project settings here:

Configuration Properties/Linker/Advanced/Import Library

I assume it's the same in Express (if it even provides the ability to configure the name).

Step 1: Here is one simple example. You have to create a SQL file from the dump file using SQLFILE option.

Step 2: Grep for CREATE USER in the generated SQL file (here tables.sql)

Example here:

$ impdp directory=exp_dir dumpfile=exp_user1_all_tab.dmp  logfile=imp_exp_user1_tab sqlfile=tables.sql

You've already gone down the list of most things that would be helpful, but you could try:

• Exit Android Studio
• Back up your project
• Delete all the .iml files and the .idea folder
• Relaunch Android Studio and reimport your project

By the way, the error messages you see in the Project Structure dialog are bogus for the most part.

UPDATE:

Android Studio 0.4.3 is available in the canary update channel, and should hopefully solve most of these issues. There may be some lingering problems; if you see them in 0.4.3, let us know, and try to give us a reliable set of steps to reproduce so we can ensure we've taken care of all code paths.

You can specify that as an additional option when setting up your client connection:

mysql -u myuser -p --local-infile somedatabase

This is because that feature opens a security hole. So you have to enable it in an explicit manner in case you really want to use it.

Both client and server should enable the local-file option. Otherwise it doesn't work.To enable it for files on the server side server add following to the my.cnf configuration file:

loose-local-infile = 1

Incredibly, my solution to the same error was to just re-arrange the columns. For anyone else doing the above solutions and still not getting past the error.

I apparently had to arrange the columns in my CSV file to match the same sequence in the table listing in PGADmin.

There are too much too long anwers in a foreign language. So I'll try to make it short.

If you write from . import module, opposite to what you think, module will not be imported from current directory, but from the top level of your package! If you run .py file as a script, it simply doesn't know where the top level is and thus refuses to work.

If you start it like this py -m package.module from the directory above package, then python knows where the top level is. That's very similar to java: java -cp bin_directory package.class

Right click your maven project in bottom of the drop down list Maven >> reimport

it works for me for the missing dependancyies

Download json from java2s website then include in your project. In your class add these package java_basic;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Iterator;

import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;

For Android Studio:

Right click on res, new Image Asset

Select the image radio button in 3rd option i.e Asset Type

Select the path of the image and click next and then finish

All the images are added to the respective folder, its very simple

For Eclim + Maven users :

1. Open the .classpath file of your project : vim .classpath.
2. Within vim, use :MvnRepo to initialize the Maven Eclim plugin. This will set M2_REPO. Note that this step *has to be performed while editing the .classpath file (hence step 1).
3. Update the list of dependencies with :Mvn dependency:resolve.
4. Update the .classpath with :Mvn eclipse:eclipse.
5. Save and exit the .classpath — :wq.
6. Restarting eclim seems to help.

Note that steps 3 and 4 can be done outside vim, with mvn dependency:resolve and mvn eclipse:eclipse, respectively.

Since the plugin is mentioned as an Eclipse plugin in Eclim’s documentation, I assume this procedure may also work for Eclipse users.

Because you imported scipy, not sparse. Try from scipy import sparse?

We need to execute the following command:

mongoimport --host=127.0.0.1 -d database_name -c collection_name --type csv --file csv_location --headerline

-d is database name

-c is collection name

--headerline If using --type csv or --type tsv, uses the first line as field names. Otherwise, mongoimport will import the first line as a distinct document.

For more information: mongoimport

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

Username as root without password

mysql -h localhost -u root databasename < dump.sql

I have faced the problem on my local host as i don't have any password for root user. You can use it without -p password as above. If it ask for password, just hit enter.

Unfortunately ES6/ES2015 doesn't support loading JSON via the module import syntax. But...

There are many ways you can do it. Depending on your needs you can either look into how to read files in JavaScript (window.FileReader could be an option if you're running in the browser) or use some other loaders as described in other questions (assuming you are using NodeJS).

IMO simplest way is probably to just put the JSON as a JS object into an ES6 module and export it. That way you can just import it where you need it.

Also worth noting if you're using Webpack, importing of JSON files will work by default (since webpack >= v2.0.0).

import config from '../config.json';

Usually it is a simple as adding apply plugin: "eclipse" in your build.gradle and running

cd myProject/
gradle eclipse

and then refreshing your Eclipse project.

Occasionally you'll need to adjust build.gradle to generate Eclipse settings in some very specific way.

There is gradle support for Eclipse if you are using STS, but I'm not sure how good it is.

The only IDE I know that has decent native support for gradle is IntelliJ IDEA. It can do full import of gradle projects from GUI. There is a free Community Edition that you can try.

An update, several years later

This answer is old, and R has moved on. Tweaking read.table to run a bit faster has precious little benefit. Your options are:

1. Using vroom from the tidyverse package vroom for importing data from csv/tab-delimited files directly into an R tibble. See Hector's answer.

2. Using fread in data.table for importing data from csv/tab-delimited files directly into R. See mnel's answer.

3. Using read_table in readr (on CRAN from April 2015). This works much like fread above. The readme in the link explains the difference between the two functions (readr currently claims to be "1.5-2x slower" than data.table::fread).

4. read.csv.raw from iotools provides a third option for quickly reading CSV files.

5. Trying to store as much data as you can in databases rather than flat files. (As well as being a better permanent storage medium, data is passed to and from R in a binary format, which is faster.) read.csv.sql in the sqldf package, as described in JD Long's answer, imports data into a temporary SQLite database and then reads it into R. See also: the RODBC package, and the reverse depends section of the DBI package page. MonetDB.R gives you a data type that pretends to be a data frame but is really a MonetDB underneath, increasing performance. Import data with its monetdb.read.csv function. dplyr allows you to work directly with data stored in several types of database.

6. Storing data in binary formats can also be useful for improving performance. Use saveRDS/readRDS (see below), the h5 or rhdf5 packages for HDF5 format, or write_fst/read_fst from the fst package.

The original answer

There are a couple of simple things to try, whether you use read.table or scan.

1. Set nrows=the number of records in your data (nmax in scan).

2. Make sure that comment.char="" to turn off interpretation of comments.

3. Explicitly define the classes of each column using colClasses in read.table.

4. Setting multi.line=FALSE may also improve performance in scan.

If none of these thing work, then use one of the profiling packages to determine which lines are slowing things down. Perhaps you can write a cut down version of read.table based on the results.

The other alternative is filtering your data before you read it into R.

Or, if the problem is that you have to read it in regularly, then use these methods to read the data in once, then save the data frame as a binary blob with save saveRDS, then next time you can retrieve it faster with load readRDS.

$i=0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
if($i>0){
    $import="INSERT into importing(text,number)values('".$data[0]."','".$data[1]."')";
    mysql_query($import) or die(mysql_error());
}
$i=1;
}

If you do not have an LDF file then:

1) put the MDF in the C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\

2) In ssms, go to Databases -> Attach and add the MDF file. It will not let you add it this way but it will tell you the database name contained within.

3) Make sure the user you are running ssms.exe as has acccess to this MDF file.

4) Now that you know the DbName, run

EXEC sp_attach_single_file_db @dbname = 'DbName', 
@physname = N'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\yourfile.mdf';

Reference: https://dba.stackexchange.com/questions/12089/attaching-mdf-without-ldf

As you can't import a .txt file, I would suggest to read words this way.

list_ = open("world.txt").read().split()

This is how you can insert into an identity column:

CREATE TABLE my_table (id INTEGER PRIMARY KEY AUTOINCREMENT, name COLLATE NOCASE);
CREATE TABLE temp_table (name COLLATE NOCASE);

.import predefined/myfile.txt temp_table 
insert into my_table (name) select name from temp_table;

myfile.txt is a file in C:\code\db\predefined\

data.db is in C:\code\db\

myfile.txt contains strings separated by newline character.

If you want to add more columns, it's easier to separate them using the pipe character, which is the default.

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

Export:

mysqldump --user=root databasename > whole.database.sql
mysqldump --user=root databasename onlySingleTableName > single.table.sql

Import:

Whole database:

mysql --user=root wholedatabase < whole.database.sql

Single table:

mysql --user=root databasename < single.table.sql

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

Just type below command on your command prompt & it will bind all sql file into single sql file,

c:/xampp/mysql/bin/sql/ type *.sql > OneFile.sql;

Not an answer here and more like a comment, sorry but I can't comment.

In node V10, you can use the flag --experimental-modules to tell Nodejs you want to use import. But your entry script should end with .mjs.

Note this is still an experimental thing and should not be used in production.

// main.mjs
import utils from './utils.js'
utils.print();

// utils.js
module.exports={
    print:function(){console.log('print called')}
}

It's a new feature called Modules or "semantic import". There's more info in the WWDC 2013 videos for Session 205 and 404. It's kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework executable and its headers and are touted as being safer and more efficient than #import.

One of the big advantages of using @import is that you don't need to add the framework in the project settings, it's done automatically. That means that you can skip the step where you click the plus button and search for the framework (golden toolbox), then move it to the "Frameworks" group. It will save many developers from the cryptic "Linker error" messages.

You don't actually need to use the @import keyword. If you opt-in to using modules, all #import and #include directives are mapped to use @import automatically. That means that you don't have to change your source code (or the source code of libraries that you download from elsewhere). Supposedly using modules improves the build performance too, especially if you haven't been using PCHs well or if your project has many small source files.

Modules are pre-built for most Apple frameworks (UIKit, MapKit, GameKit, etc). You can use them with frameworks you create yourself: they are created automatically if you create a Swift framework in Xcode, and you can manually create a ".modulemap" file yourself for any Apple or 3rd-party library.

You can use code-completion to see the list of available frameworks:

Modules are enabled by default in new projects in Xcode 5. To enable them in an older project, go into your project build settings, search for "Modules" and set "Enable Modules" to "YES". The "Link Frameworks" should be "YES" too:

You have to be using Xcode 5 and the iOS 7 or Mavericks SDK, but you can still release for older OSs (say iOS 4.3 or whatever). Modules don't change how your code is built or any of the source code.

From the WWDC slides:

• Imports complete semantic description of a framework
• Doesn't need to parse the headers
• Better way to import a framework’s interface
• Loads binary representation
• More flexible than precompiled headers
• Immune to effects of local macro definitions (e.g. #define readonly 0x01)
• Enabled for new projects by default

To explicitly use modules:

Replace #import <Cocoa/Cocoa.h> with @import Cocoa;

You can also import just one header with this notation:

@import iAd.ADBannerView;

The submodules autocomplete for you in Xcode.

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

If you are ok with discarding nonconvertible characters, you can use -c flag

iconv -c -t utf8 filename.csv > filename.utf8.csv

and then copy them to your table

I also search for an answer to your question. Correspond to the answers the correct import all function does not exist.

Thats why I have written a python script which you need to place into the root of your scss folder like so:

- scss
  |- scss-crawler.py
  |- abstract
  |- base
  |- components
  |- layout
  |- themes
  |- vender

It will then walk through the tree and find all scss files. Once executed, it will create a scss file called main.scss

#python3
import os

valid_file_endings = ["scss"]

with open("main.scss", "w") as scssFile:
    for dirpath, dirs, files in os.walk("."):
        # ignore the current path where the script is placed
        if not dirpath == ".":
            # change the dir seperator
            dirpath = dirpath.replace("\\", "/")

            currentDir = dirpath.split("/")[-1]
            # filter out the valid ending scss
            commentPrinted = False
            for file in files:
                # if there is a file with more dots just focus on the last part
                fileEnding = file.split(".")[-1]
                if fileEnding in valid_file_endings:
                    if not commentPrinted:
                        print("/* {0} */".format(currentDir), file = scssFile)
                        commentPrinted = True
                    print("@import '{0}/{1}';".format(dirpath, file.split(".")[0][1:]), file = scssFile)

an example of an output file:

/* abstract */
@import './abstract/colors';
/* base */
@import './base/base';
/* components */
@import './components/audioPlayer';
@import './components/cardLayouter';
@import './components/content';
@import './components/logo';
@import './components/navbar';
@import './components/songCard';
@import './components/whoami';
/* layout */
@import './layout/body';
@import './layout/header';

Importing Swift file inside Objective-c can cause this error, if it doesn't import properly.

NOTE: You don't have to import Swift files externally, you just have to import one file which takes care of swift files.

When you Created/Copied Swift file inside Objective-C project. It would've created a bridging header automatically.

Check Objective-C Generated Interface Header Name at Targets -> Build Settings.

Based on above, I will import KJExpandable-Swift.h as it is.

Your's will be TargetName-Swift.h, Where TargetName differs based on your project name or another target your might have added and running on it.

As below my target is KJExpandable, so it's KJExpandable-Swift.h

It is not a compilation error at all! You can import a default package to a default package class only.

If you do so for another package, then it shall be a compilation error.

This command works where no collection is specified .

mongoimport --db zips "\MongoDB 2.6 Standard\mongodb\zips.json"

Mongo shell after executing the command

2014-09-16T13:56:07.148-0400 imported 29353 objects

None of these solutions worked for me in 3.6, with a folder structure like:

package1/
    subpackage1/
        module1.py
package2/
    subpackage2/
        module2.py

My goal was to import from module1 into module2. What finally worked for me was, oddly enough:

import sys
sys.path.append(".")

Note the single dot as opposed to the two-dot solutions mentioned so far.

Edit: The following helped clarify this for me:

import os
print (os.getcwd())

In my case, the working directory was (unexpectedly) the root of the project.

You should also read about python packages here: http://docs.python.org/tutorial/modules.html.

From your example, I would guess that you really have a package at ~/codez/project. The file __init__.py in a python directory maps a directory into a namespace. If your subdirectories all have an __init__.py file, then you only need to add the base directory to your PYTHONPATH. For example:

PYTHONPATH=$PYTHONPATH:$HOME/adaifotis/project

In addition to testing your PYTHONPATH environment variable, as David explains, you can test it in python like this:

$ python
>>> import project                      # should work if PYTHONPATH set
>>> import sys
>>> for line in sys.path: print line    # print current python path

...

Take a look at this forum http://htmlcoderhelper.com/why-is-using-a-wild-card-with-a-java-import-statement-bad/. Theres a discussion on how using wildcards can lead to conflicts if you add new classes to the packages and if there are two classes with the same name in different packages where only one of them will be imported.

Update

List<Integer> i = new ArrayList<Integer>(Arrays.asList(0,1,2,3,4,5,6,7,8,9,10));
List<Integer> j = new ArrayList<Integer>();

You need to specify the type for array list or the compiler will give that warning because it cannot identify that you are using the list in a type safe way.

Any number of files in a directory are a single package; symbols declared in one file are available to the others without any imports or qualifiers. All of the files do need the same package foo declaration at the top (or you'll get an error from go build).

You do need GOPATH set to the directory where your pkg, src, and bin directories reside. This is just a matter of preference, but it's common to have a single workspace for all your apps (sometimes $HOME), not one per app.

Normally a Github path would be github.com/username/reponame (not just github.com/xxxx). So if you want to have main and another package, you may end up doing something under workspace/src like

github.com/
  username/
    reponame/
      main.go   // package main, importing "github.com/username/reponame/b"
      b/
        b.go    // package b

Note you always import with the full github.com/... path: relative imports aren't allowed in a workspace. If you get tired of typing paths, use goimports. If you were getting by with go run, it's time to switch to go build: run deals poorly with multiple-file mains and I didn't bother to test but heard (from Dave Cheney here) go run doesn't rebuild dirty dependencies.

Sounds like you've at least tried to set GOPATH to the right thing, so if you're still stuck, maybe include exactly how you set the environment variable (the command, etc.) and what command you ran and what error happened. Here are instructions on how to set it (and make the setting persistent) under Linux/UNIX and here is the Go team's advice on workspace setup. Maybe neither helps, but take a look and at least point to which part confuses you if you're confused.

The import wizard does offer that option. You can either use the option to write your own query for the data to import, or you can use the copy data option and use the "Edit Mappings" button to ignore columns you do not want to import.

The other answers cover the 2 most common approaches, Xinclude and XML external entities. Microsoft has a really great writeup on why one should prefer Xinclude, as well as several example implementations. I've quoted the comparison below:

Per http://msdn.microsoft.com/en-us/library/aa302291.aspx

Why XInclude?

The first question one may ask is "Why use XInclude instead of XML external entities?" The answer is that XML external entities have a number of well-known limitations and inconvenient implications, which effectively prevent them from being a general-purpose inclusion facility. Specifically:

• An XML external entity cannot be a full-blown independent XML document—neither standalone XML declaration nor Doctype declaration is allowed. That effectively means an XML external entity itself cannot include other external entities.
• An XML external entity must be well formed XML (not so bad at first glance, but imagine you want to include sample C# code into your XML document).
• Failure to load an external entity is a fatal error; any recovery is strictly forbidden.
• Only the whole external entity may be included, there is no way to include only a portion of a document. -External entities must be declared in a DTD or an internal subset. This opens a Pandora's Box full of implications, such as the fact that the document element must be named in Doctype declaration and that validating readers may require that the full content model of the document be defined in DTD among others.

The deficiencies of using XML external entities as an inclusion mechanism have been known for some time and in fact spawned the submission of the XML Inclusion Proposal to the W3C in 1999 by Microsoft and IBM. The proposal defined a processing model and syntax for a general-purpose XML inclusion facility.

Four years later, version 1.0 of the XML Inclusions, also known as Xinclude, is a Candidate Recommendation, which means that the W3C believes that it has been widely reviewed and satisfies the basic technical problems it set out to solve, but is not yet a full recommendation.

Another good site which provides a variety of example implementations is https://www.xml.com/pub/a/2002/07/31/xinclude.html. Below is a common use case example from their site:

<book xmlns:xi="http://www.w3.org/2001/XInclude">

  <title>The Wit and Wisdom of George W. Bush</title>

  <xi:include href="malapropisms.xml"/>

  <xi:include href="mispronunciations.xml"/>

  <xi:include href="madeupwords.xml"/>

</book>

The file basically contain data for two new tables.

Then you may find it simpler to just DTS (or SSIS, if this is SQL Server 2005+) the data over, if the two servers are on the same network.

If the two servers are not on the same network, you can backup the source database and restore it to a new database on the destination server. Then you can use DTS/SSIS, or even a simple INSERT INTO SELECT, to transfer the two tables to the destination database.

This answer helped to me download image from server to client side.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

By these days (ending 2019) I prefer to use a tool like http://www.convertcsv.com/csv-to-sql.htm I you got a lot of rows you can run partitioned blocks saving user mistakes when csv come from a final user spreadsheet.

I was having the same trouble and I did

pip install pygame

and that worked for me!

It's ridiculous that java doesn't have this yet. Scala has it

import com.text.Formatter
import com.json.{Formatter => JsonFormatter}

val Formatter textFormatter;
val JsonFormatter jsonFormatter;

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

We can also import static methods/fields in Java and this is how to import

import static full.package.nameOfClass.staticMethod;
import static full.package.nameOfClass.staticField;

Make sure if root project directory is coming up in sys.path output. If not, please add path of root project directory to sys.path.

This is for Android Studio 1.0.2(Windows7). Right click on the project on project bar and delete.

Then remove the project folder from within your user folder under 'AndroidStudioProject' using Windows explorer.

Close the studio and relaunch you will presented with welcome screen. Click on deleted project from left side pane then select the option to remove from the list. Done!

The following works for me in Firefox and Chrome. In Firefox it even works from file:///

models/course.js

export function Course() {
    this.id = '';
    this.name = '';
};

models/student.js

import { Course } from './course.js';

export function Student() {
    this.firstName = '';
    this.lastName = '';
    this.course = new Course();
};

index.html

<div id="myDiv">
</div>
<script type="module">
    import { Student } from './models/student.js';

    window.onload = function () {
        var x = new Student();
        x.course.id = 1;
        document.getElementById('myDiv').innerHTML = x.course.id;
    }
</script>

They're equivalent. The access is the same.

The import is just a convention to save you from having to type the fully-resolved class name each time. You can write all your Java without using import, as long as you're a fast touch typer.

But there's no difference in efficiency or class loading.

Actually this is not really the same to import a variable with:

from file1 import x1
print(x1)

and

import file1
print(file1.x1)

Altough at import time x1 and file1.x1 have the same value, they are not the same variables. For instance, call a function in file1 that modifies x1 and then try to print the variable from the main file: you will not see the modified value.

Here is a plain and simple explanation:

Server.js content:

// Include the public functions from 'helpers.js'
var helpers = require('./helpers');

// Let's assume this is the data which comes from the database or somewhere else
var databaseName = 'Walter';
var databaseSurname = 'Heisenberg';

// Use the function from 'helpers.js' in the main file, which is server.js
var fullname = helpers.concatenateNames(databaseName, databaseSurname);

Helpers.js content:

// 'module.exports' is a node.JS specific feature, it does not work with regular JavaScript
module.exports = 
{
  // This is the function which will be called in the main file, which is server.js
  // The parameters 'name' and 'surname' will be provided inside the function
  // when the function is called in the main file.
  // Example: concatenameNames('John,'Doe');
  concatenateNames: function (name, surname) 
  {
     var wholeName = name + " " + surname;

     return wholeName;
  },

  sampleFunctionTwo: function () 
  {

  }
};

// Private variables and functions which will not be accessible outside this file
var privateFunction = function () 
{
};

Data can be pulled into an excel from another excel through Workbook method or External reference or through Data Import facility.

If you want to read or even if you want to update another excel workbook, these methods can be used. We may not depend only on VBA for this.

You should have the file at the same location as that of the Python files you are trying to import. Also 'from file import function' is enough.

You could also use JDBC to achieve this. Let's create a sample csv file.

write.table(x=mtcars, file="mtcars.csv", sep=",", row.names=F, col.names=T) # create example csv file

Download and save the the CSV JDBC driver from this link: http://sourceforge.net/projects/csvjdbc/files/latest/download

> library(RJDBC)

> path.to.jdbc.driver <- "jdbc//csvjdbc-1.0-18.jar"
> drv <- JDBC("org.relique.jdbc.csv.CsvDriver", path.to.jdbc.driver)
> conn <- dbConnect(drv, sprintf("jdbc:relique:csv:%s", getwd()))

> head(dbGetQuery(conn, "select * from mtcars"), 3)

I was trying to import numpy in python 3.2.1 on windows 7.

Followed suggestions in above answer for numpy-1.6.1.zip as below after unzipping it

cd numpy-1.6
python setup.py install

but got an error with a statement as below

unable to find vcvarsall.bat

For this error I found a related question here which suggested installing mingW. MingW was taking some time to install.

In the meanwhile tried to install numpy 1.6 again using the direct windows installer available at this link the file name is "numpy-1.6.1-win32-superpack-python3.2.exe"

Installation went smoothly and now I am able to import numpy without using mingW.

Long story short try using windows installer for numpy, if one is available.

From the command line:

psql -f 1.sql
psql -f 2.sql

From the psql prompt:

\i 1.sql
\i 2.sql

Note that you may need to import the files in a specific order (for example: data definition before data manipulation). If you've got bash shell (GNU/Linux, Mac OS X, Cygwin) and the files may be imported in the alphabetical order, you may use this command:

for f in *.sql ; do psql -f $f ; done

Here's the documentation of the psql application (thanks, Frank): http://www.postgresql.org/docs/current/static/app-psql.html

As stated in other answers, this error may refer to using the wrong python version. In my case, my environment is Windows 10 + Cygwin. In my Windows environment variables, the PATH points to C:\Python38 which is correct, but when I run my command like this:

./my_script.py

I got the ImportError: No module named numpy because the version used in this case is Cygwin's own Python version even if PATH environment variable is correct. All I needed was to run the script like this:

py my_script.py

And this way the problem was solved.

you can't. foo-bar is not an identifier. rename the file to foo_bar.py

Edit: If import is not your goal (as in: you don't care what happens with sys.modules, you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile

# contents of foo-bar.py
baz = 'quux'

>>> execfile('foo-bar.py')
>>> baz
'quux'
>>> 

Since ID is auto increment, you can also specify ID=NULL as,

LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename SET ID=NULL;

I do this for credit card numbers which keep converting to scientific notation: I end up importing my .csv into Google Sheets. The import options now allow to disable automatic formatting of numeric values. I set any sensitive columns to Plain Text and download as xlsx.

It's a terrible workflow, but at least my values are left the way they should be.

% Assuming that the dataset is ";"-delimited and each line ends with ";"
fid = fopen('sampledata.csv');
tline = fgetl(fid);
u=sprintf('%c',tline); c=length(u);
id=findstr(u,';'); n=length(id);
data=cell(1,n);
for I=1:n
    if I==1
        data{1,I}=u(1:id(I)-1);
    else
        data{1,I}=u(id(I-1)+1:id(I)-1);
    end
end
ct=1;
while ischar(tline)
    ct=ct+1;
    tline = fgetl(fid);
    u=sprintf('%c',tline);
    id=findstr(u,';');
    if~isempty(id)
        for I=1:n
            if I==1
                data{ct,I}=u(1:id(I)-1);
            else
                data{ct,I}=u(id(I-1)+1:id(I)-1);
            end
        end
    end
end
fclose(fid);

The issue is most likely you will need to use an auto loader that will take the name of the class (break by '\' in this case) and map it to a directory structure.

You can check out this article on the autoloading functionality of PHP. There are many implementations of this type of functionality in frameworks already.

I've actually implemented one before. Here's a link.

For 2020.1.4 Ultimate edition, I had to do the following

View -> Maven -> Generate Sources and Update Folders For all Projects

The issue for me was the libraries were not getting populated with mvn -U clean install from the terminal.

In order to understand the use of curly braces in import statements, first, you have to understand the concept of destructuring introduced in ES6

1. Object destructuring

   var bodyBuilder = {
     firstname: 'Kai',
     lastname: 'Greene',
     nickname: 'The Predator'
   };
   
   var {firstname, lastname} = bodyBuilder;
   console.log(firstname, lastname); // Kai Greene
   
   firstname = 'Morgan';
   lastname = 'Aste';
   
   console.log(firstname, lastname); // Morgan Aste
   

2. Array destructuring

   var [firstGame] = ['Gran Turismo', 'Burnout', 'GTA'];
   
   console.log(firstGame); // Gran Turismo
   

   Using list matching

     var [,secondGame] = ['Gran Turismo', 'Burnout', 'GTA'];
     console.log(secondGame); // Burnout
   

   Using the spread operator

   var [firstGame, ...rest] = ['Gran Turismo', 'Burnout', 'GTA'];
   console.log(firstGame);// Gran Turismo
   console.log(rest);// ['Burnout', 'GTA'];
   

Now that we've got that out of our way, in ES6 you can export multiple modules. You can then make use of object destructuring like below.

Let's assume you have a module called module.js

    export const printFirstname(firstname) => console.log(firstname);
    export const printLastname(lastname) => console.log(lastname);

You would like to import the exported functions into index.js;

    import {printFirstname, printLastname} from './module.js'

    printFirstname('Taylor');
    printLastname('Swift');

You can also use different variable names like so

    import {printFirstname as pFname, printLastname as pLname} from './module.js'

    pFname('Taylor');
    pLanme('Swift');

Java doesn't use includes the way C does. Instead java uses a concept called the classpath, a list of resources containing java classes. The JVM can access any class on the classpath by name so if you can extend classes and refer to types simply by declaring them. The closes thing to an include statement java has is 'import'. Since classes are broken up into namespaces like foo.bar.Baz, if you're in the qux package and you want to use the Baz class without having to use its full name of foo.bar.Baz, then you need to use an import statement at the beginning of your java file like so: import foo.bar.Baz

Doing a relative import is absolulutely OK! Here's what little 'ol me does:

#first change the cwd to the script path
scriptPath = os.path.realpath(os.path.dirname(sys.argv[0]))
os.chdir(scriptPath)

#append the relative location you want to import from
sys.path.append("../common")

#import your module stored in '../common'
import common.py

Note that once you have imported the google-play-services_lib project into your IDE, you will also need to add google-play-services.jar to: Project=>Properties=>Java build path=>Libraries=>Add JARs

I have a perfect solution for this problem. After doing following simple steps you will be able to Import your source codes in Eclipse!

First of all, the reason why you can not Import your project into Eclipse workstation is that you do not have .project and .classpath file.

Now we know why this happens, so all we need to do is to create .project and .classpath file inside the project file. Here is how you do it:

First create .classpath file:

1. create a new txt file and name it as .classpath

2. copy paste following codes and save it:

   <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> </classpath>

Then create .project file:

1. create a new txt file and name it as .project

2. copy paste following codes:

   <?xml version="1.0" encoding="UTF-8"?> <projectDescription> <name>HereIsTheProjectName</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>org.eclipse.jdt.core.javanature</nature> </natures> </projectDescription>

3. you have to change the name field to your project name. you can do this in line 3 by changing HereIsTheProjectName to your own project name. then save it.

That is all, Enjoy!!

You can also use OPENROWSET to import excel file in sql server.

SELECT * INTO Your_Table FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
                        'Excel 12.0;Database=C:\temp\MySpreadsheet.xlsx',
                        'SELECT * FROM [Data$]')

IntelliJ

Control + Option + o (not a zero, letter "o")

If you are using wamp you can try this. Just type use your_Database_name first.

1. Click your wamp server icon then look for MYSQL > MSQL Console then run it.

2. If you dont have password, just hit enter and type :

   mysql> use database_name;
   mysql> source location_of_your_file;
   

   If you have password, you will promt to enter a password. Enter you password first then type:

   mysql> use database_name;
   mysql> source location_of_your_file;
   

location_of_your_file should look like C:\mydb.sql

so the commend is mysql>source C:\mydb.sql;

This kind of importing sql dump is very helpful for BIG SQL FILE.

I copied my file mydb.sq to directory C: .It should be capital C: in order to run

and that's it.

Sometimes the port defined as well as the server IP address of that database also matters...

mysql -u user -p user -h <Server IP> -P<port> (DBNAME) < DB.sql 

Just create an empty __init__.py file and add it in root as well as all the sub directory/folder of your python application where you have other python modules. See https://docs.python.org/3/tutorial/modules.html#packages

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

I think it's better to use importlib.import_module('.c', __name__) since you don't need to know about a and b.

I'm also wondering that, if you have to use importlib.import_module('a.b.c'), why not just use import a.b.c?

pow is built into the language(not part of the math library). The problem is that you haven't imported math.

Try this:

import math
math.sqrt(4)

1. It helps to identify classname conflicts: two classes in different packages that have the same name. This can be masked with the * import.
2. It makes dependencies explicit, so that anyone who has to read your code later knows what you meant to import and what you didn't mean to import.
3. It can make some compilation faster because the compiler doesn't have to search the whole package to identify depdencies, though this is usually not a huge deal with modern compilers.
4. The inconvenient aspects of explicit imports are minimized with modern IDEs. Most IDEs allow you to collapse the import section so it's not in the way, automatically populate imports when needed, and automatically identify unused imports to help clean them up.

Most places I've worked that use any significant amount of Java make explicit imports part of the coding standard. I sometimes still use * for quick prototyping and then expand the import lists (some IDEs will do this for you as well) when productizing the code.

You can use the below syntax -

from FolderName.FileName import Classname

Just add classpath entry ( I mean your parent directory location) under System Variables and User Variables menu ... Follow : Right Click My Computer>Properties>Advanced>Environment Variables

I was using the following:

from module import Foo

foo_instance = Foo()

but to get rid of circular reference I did the following and it worked:

import module.foo

foo_instance = foo.Foo()

I wanted to share with you my solution to export a database with Microsoft SQL Server Management Studio.

To Export your database

1. Open a new request
2. Copy paste this script

DECLARE @BackupFile NVARCHAR(255);
SET @BackupFile = 'c:\database-backup_2020.07.22.bak';
PRINT @BackupFile;
BACKUP DATABASE [%databaseName%] TO DISK = @BackupFile;

Don't forget to replace %databaseName% with the name of the database you want to export.

Note that this method gives a lighter file than from the menu.

To import this file from SQL Server Management Studio. Don't forget to delete your database beforehand.

1. Click restore database

2. Add the backup file

3. Validate

Enjoy! :) :)

I just wrote this JavaScript code (using Prototype for DOM manipulation):

var require = (function() {
    var _required = {};
    return (function(url, callback) {
        if (typeof url == 'object') {
            // We've (hopefully) got an array: time to chain!
            if (url.length > 1) {
                // Load the nth file as soon as everything up to the
                // n-1th one is done.
                require(url.slice(0, url.length - 1), function() {
                    require(url[url.length - 1], callback);
                });
            } else if (url.length == 1) {
                require(url[0], callback);
            }
            return;
        }
        if (typeof _required[url] == 'undefined') {
            // Haven't loaded this URL yet; gogogo!
            _required[url] = [];

            var script = new Element('script', {
                src: url,
                type: 'text/javascript'
            });
            script.observe('load', function() {
                console.log("script " + url + " loaded.");
                _required[url].each(function(cb) {
                    cb.call(); // TODO: does this execute in the right context?
                });
                _required[url] = true;
            });

            $$('head')[0].insert(script);
        } else if (typeof _required[url] == 'boolean') {
            // We already loaded the thing, so go ahead.
            if (callback) {
                callback.call();
            }
            return;
        }

        if (callback) {
            _required[url].push(callback);
        }
    });
})();

Usage:

<script src="prototype.js"></script>
<script src="require.js"></script>
<script>
    require(['foo.js','bar.js'], function () {
        /* Use foo.js and bar.js here */
    });
</script>

Simpler version of yfeldblum's answer, that is simpler and works well also with large files:

require 'csv'    

CSV.foreach(filename, headers: true) do |row|
  Moulding.create!(row.to_hash)
end

No need for with_indifferent_access or symbolize_keys, and no need to read in the file to a string first.

It doesnt't keep the whole file in memory at once, but reads in line by line and creates a Moulding per line.

Import by using the import keyword:

import package.myclass;

But since it's the default package and same, you just create a new instance like:

elf ob = new elf(); //Instance of elf class

I solved a similar problem by enveloping all css instructions in a php echo and then saving it as a php file (ofcourse starting and ending the file with the php tags), and then included the php file. This was a necessity as a redirect followed (header ("somefilename.php")) and no html code is allowed before a redirect.

Following worked for me and it seems very simple as well:

Let's assume that we want to import a script ./data/get_my_file.py and want to access get_set1() function in it.

import sys
sys.path.insert(0, './data/')
import get_my_file as db

print (db.get_set1())

The best way is to user sass-loader. It is available as npm package. It resolves all path related issues and make it super easy.

You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath.

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.

If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.

For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.

If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.

There is no problem at all using Jupyter with existing or new Python .py modules. With Jupyter running, simply fire up Spyder (or any editor of your choice) to build / modify your module class definitions in a .py file, and then just import the modules as needed into Jupyter.

One thing that makes this really seamless is using the autoreload magic extension. You can see documentation for autoreload here:

http://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html

Here is the code to automatically reload the module any time it has been modified:

# autoreload sets up auto reloading of modified .py modules
import autoreload
%load_ext autoreload
%autoreload 2

Note that I tried the code mentioned in a prior reply to simulate loading .ipynb files as modules, and got it to work, but it chokes when you make changes to the .ipynb file. It looks like you need to restart the Jupyter development environment in order to reload the .ipynb 'module', which was not acceptable to me since I am making lots of changes to my code.

in python the operators should be in quotes: db.ProductData.update({'fromAddress':'http://localhost:7000/'}, {"$set": {'fromAddress': 'http://localhost:5000/'}},{"multi": True})

Chiming in to recommend the use of the xmltodict library. It handled your xml text pretty well and I've used it for ingesting an xml file with almost a million records.

It's the index column, pass pd.to_csv(..., index=False) to not write out an unnamed index column in the first place, see the to_csv() docs.

Example:

In [37]:
df = pd.DataFrame(np.random.randn(5,3), columns=list('abc'))
pd.read_csv(io.StringIO(df.to_csv()))

Out[37]:
   Unnamed: 0         a         b         c
0           0  0.109066 -1.112704 -0.545209
1           1  0.447114  1.525341  0.317252
2           2  0.507495  0.137863  0.886283
3           3  1.452867  1.888363  1.168101
4           4  0.901371 -0.704805  0.088335

compare with:

In [38]:
pd.read_csv(io.StringIO(df.to_csv(index=False)))

Out[38]:
          a         b         c
0  0.109066 -1.112704 -0.545209
1  0.447114  1.525341  0.317252
2  0.507495  0.137863  0.886283
3  1.452867  1.888363  1.168101
4  0.901371 -0.704805  0.088335

You could also optionally tell read_csv that the first column is the index column by passing index_col=0:

In [40]:
pd.read_csv(io.StringIO(df.to_csv()), index_col=0)

Out[40]:
          a         b         c
0  0.109066 -1.112704 -0.545209
1  0.447114  1.525341  0.317252
2  0.507495  0.137863  0.886283
3  1.452867  1.888363  1.168101
4  0.901371 -0.704805  0.088335

The key things here are

1. The entries in the array are objects, and
2. You don't want modifications to an object in one array to show up in the other array.

That means we need to not just copy the objects to a new array (or a target array), but also create copies of the objects.

If the destination array doesn't exist yet...

...use map to create a new array, and copy the objects as you go:

const newArray = sourceArray.map(obj => /*...create and return copy of `obj`...*/);

...where the copy operation is whatever way you prefer to copy objects, which varies tremendously project to project based on use case. That topic is covered in depth in the answers to this question. But for instance, if you only want to copy the objects but not any objects their properties refer to, you could use spread notation (ES2015+):

const newArray = sourceArray.map(obj => ({...obj}));

That does a shallow copy of each object (and of the array). Again, for deep copies, see the answers to the question linked above.

Here's an example using a naive form of deep copy that doesn't try to handle edge cases, see that linked question for edge cases:

function naiveDeepCopy(obj) {
    const newObj = {};
    for (const key of Object.getOwnPropertyNames(obj)) {
        const value = obj[key];
        if (value && typeof value === "object") {
            newObj[key] = {...value};
        } else {
            newObj[key] = value;
        }
    }
    return newObj;
}
const sourceArray = [
    {
        name: "joe",
        address: {
            line1: "1 Manor Road",
            line2: "Somewhere",
            city: "St Louis",
            state: "Missouri",
            country: "USA",
        },
    },
    {
        name: "mohammed",
        address: {
            line1: "1 Kings Road",
            city: "London",
            country: "UK",
        },
    },
    {
        name: "shu-yo",
    },
];
const newArray = sourceArray.map(naiveDeepCopy);
// Modify the first one and its sub-object
newArray[0].name = newArray[0].name.toLocaleUpperCase();
newArray[0].address.country = "United States of America";
console.log("Original:", sourceArray);
console.log("Copy:", newArray);

.as-console-wrapper {
    max-height: 100% !important;
}

If the destination array exists...

...and you want to append the contents of the source array to it, you can use push and a loop:

for (const obj of sourceArray) {
    destinationArray.push(copy(obj));
}

Sometimes people really want a "one liner," even if there's no particular reason for it. If you refer that, you could create a new array and then use spread notation to expand it into a single push call:

destinationArray.push(...sourceArray.map(obj => copy(obj)));

Because you say

struct arg_struct *args = (struct arg_struct *)args;

instead of

struct arg_struct *args = arguments;

variable declares and call like this in a class

class X {
    var x: Int = 3

}
var y = X()
print("value of x is: ", y.x)

//value of x is:  3

now you want to program to make the default value of x more than or equal to 3. Now take the hypothetical case if x is less than 3, your program will fail. so, you want people to either put 3 or more than 3. Swift got it easy for you and it is important to understand this bit-advance way of dating the variable value because they will extensively use in iOS development. Now let's see how get and set will be used here.

class X {
    var _x: Int = 3
    var x: Int {
        get {
            return _x
        }
        set(newVal) {  //set always take 1 argument
            if newVal >= 3 {
             _x = newVal //updating _x with the input value by the user
            print("new value is: ", _x)
            }
            else {
                print("error must be greater than 3")
            }
        }
    }
}
let y = X()
y.x = 1
print(y.x) //error must be greater than 3
y.x = 8 // //new value is: 8

if you still have doubts, just remember, the use of get and set is to update any variable the way we want it to be updated. get and set will give you better control to rule your logic. Powerful tool hence not easily understandable.

Since AIX doesn't have a "column" command, I created the simplistic script below. It would be even shorter without the doc & input edits... :)

#!/usr/bin/perl
#       column.pl: convert STDIN to multiple columns on STDOUT
#       Usage: column.pl column-width number-of-columns  file...
#
$width = shift;
($width ne '') or die "must give column-width and number-of-columns\n";
$columns = shift;
($columns ne '') or die "must give number-of-columns\n";
($x = $width) =~ s/[^0-9]//g;
($x eq $width) or die "invalid column-width: $width\n";
($x = $columns) =~ s/[^0-9]//g;
($x eq $columns) or die "invalid number-of-columns: $columns\n";

$w = $width * -1; $c = $columns;
while (<>) {
        chomp;
        if ( $c-- > 1 ) {
                printf "%${w}s", $_;
                next;
        }
        $c = $columns;
        printf "%${w}s\n", $_;
}
print "\n";

Windows 10 appears to have a keyboard shortcut. According to How to open elevated command prompt in Windows 10 you can press ctrl + shift + enter from the search or start menu after typing cmd for the search term.

Trying to uninstall Python with

brew uninstall python

will not remove the natively installed Python but rather the version installed with brew.

ActiveRecord::Base.connection has a quote method that takes a string value (and optionally the column object). So you can say this:

ActiveRecord::Base.connection.execute(<<-EOQ)
  UPDATE  foo
  SET     bar = #{ActiveRecord::Base.connection.quote(baz)}
EOQ

Note if you're in a Rails migration or an ActiveRecord object you can shorten that to:

connection.execute(<<-EOQ)
  UPDATE  foo
  SET     bar = #{connection.quote(baz)}
EOQ

UPDATE: As @kolen points out, you should use exec_update instead. This will handle the quoting for you and also avoid leaking memory. The signature works a bit differently though:

connection.exec_update(<<-EOQ, "SQL", [[nil, baz]])
  UPDATE  foo
  SET     bar = $1
EOQ

Here the last param is a array of tuples representing bind parameters. In each tuple, the first entry is the column type and the second is the value. You can give nil for the column type and Rails will usually do the right thing though.

There are also exec_query, exec_insert, and exec_delete, depending on what you need.

You can make your own itoa, with this function:

void my_utoa(int dataIn, char* bffr, int radix){
int temp_dataIn;
temp_dataIn = dataIn;
int stringLen=1;

while ((int)temp_dataIn/radix != 0){
    temp_dataIn = (int)temp_dataIn/radix;
    stringLen++;
}
//printf("stringLen = %d\n", stringLen);
temp_dataIn = dataIn;
do{
    *(bffr+stringLen-1) = (temp_dataIn%radix)+'0';
    temp_dataIn = (int) temp_dataIn / radix;
}while(stringLen--);}

and this is example:

char buffer[33];
int main(){
  my_utoa(54321, buffer, 10);
  printf(buffer);
  printf("\n");

  my_utoa(13579, buffer, 10);
  printf(buffer);
  printf("\n");
}

arr.length = Math.min(arr.length, 5)

I ran some other question regarding ARIA. But it's content looks more promising for this question. would like to share them

What is ARIA?

If you put effort into making your website accessible to users with a variety of different browsing habits and physical disabilities, you'll likely recognize the role and aria-* attributes. WAI-ARIA (Accessible Rich Internet Applications) is a method of providing ways to define your dynamic web content and applications so that people with disabilities can identify and successfully interact with it. This is done through roles that define the structure of the document or application, or through aria-* attributes defining a widget-role, relationship, state, or property.

ARIA use is recommended in the specifications to make HTML5 applications more accessible. When using semantic HTML5 elements, you should set their corresponding role.

And see this you tube video for ARIA live.

VB.NET Sample Code

Dim A as String = "5.3"
Dim B as Double

B = CDbl(Val(A)) '// Val do hard work

'// Get output 
MsgBox (B) '// Output is 5,3 Without Val result is 53.0

You likely don't have a CA signed certificate installed in your SQL VM's trusted root store.

If you have Encrypt=True in the connection string, either set that to off (not recommended), or add the following in the connection string:

TrustServerCertificate=True

SQL Server will create a self-signed certificate if you don't install one for it to use, but it won't be trusted by the caller since it's not CA-signed, unless you tell the connection string to trust any server cert by default.

Long term, I'd recommend leveraging Let's Encrypt to get a CA signed certificate from a known trusted CA for free, and install it on the VM. Don't forget to set it up to automatically refresh. You can read more on this topic in SQL Server books online under the topic of "Encryption Hierarchy", and "Using Encryption Without Validation".

$ cat .git/refs/heads/feature/user_controlled_site_layouts

Can you confirm that the following works:

$ git show 3af84fcf1508c44013844dcd0998a14e61455034

It could be the case that someone has rewritten the history and that this commit no longer exists (for whatever reason really).

If you want to clean the whole database, you can use: python manage.py flush If you want to clean database table of a Django app, you can use: python manage.py migrate appname zero

I decided to answer how to use keychain in iOS 8 using Obj-C and ARC.

1)I used the keychainItemWrapper (ARCifief version) from GIST: https://gist.github.com/dhoerl/1170641/download - Add (+copy) the KeychainItemWrapper.h and .m to your project

2) Add the Security framework to your project (check in project > Build phases > Link binary with Libraries)

3) Add the security library (#import ) and KeychainItemWrapper (#import "KeychainItemWrapper.h") to the .h and .m file where you want to use keychain.

4) To save data to keychain:

NSString *emailAddress = self.txtEmail.text;
NSString *password = self.txtPasword.text;
//because keychain saves password as NSData object
NSData *pwdData = [password dataUsingEncoding:NSUTF8StringEncoding];

//Save item
self.keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"YourAppLogin" accessGroup:nil];
[self.keychainItem setObject:emailAddress forKey:(__bridge id)(kSecAttrAccount)];
[self.keychainItem setObject:pwdData forKey:(__bridge id)(kSecValueData)];

5) Read data (probably login screen on loading > viewDidLoad):

self.keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"YourAppLogin" accessGroup:nil];

self.txtEmail.text = [self.keychainItem objectForKey:(__bridge id)(kSecAttrAccount)];

//because label uses NSString and password is NSData object, conversion necessary
NSData *pwdData = [self.keychainItem objectForKey:(__bridge id)(kSecValueData)];
NSString *password = [[NSString alloc] initWithData:pwdData encoding:NSUTF8StringEncoding];
self.txtPassword.text = password;

Enjoy!

Java 8 collection streams :

StringBuilder sb = new StringBuilder();
test.chars().mapToObj(i -> (char) i).filter(Character::isDigit).forEach(sb::append);
System.out.println(sb.toString());

You can try this if you are passing a value to the action method.

@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() { Text = "Newest to Oldest", Value = "0" }, new SelectListItem() { Text = "Oldest to Newest", Value = "1" }},new { onchange = "document.location.href = '/ControllerName/ActionName?id=' + this.options[this.selectedIndex].value;" })

Remove the query string in case of no parameter passing.

A slight improvement on the Flash solution is to detect for flash 10 using swfobject:

http://code.google.com/p/swfobject/

and then if it shows as flash 10, try loading a Shockwave object using javascript. Shockwave can read/write to the clipboard(in all versions) as well using the copyToClipboard() command in lingo.

SOLVED: On Debian 10 by adding "EXPORT TERM=xterm" on the Script executed by CRONTAB (root) but executed as www-data.

$ crontab -e

*/15 * * * * /bin/su - www-data -s /bin/bash -c '/usr/local/bin/todos.sh'

FILE=/usr/local/bin/todos.sh

#!/bin/bash -p
export TERM=xterm && cd /var/www/dokuwiki/data/pages && clear && grep -r -h '|(TO-DO)' > /var/www/todos.txt && chmod 664 /var/www/todos.txt && chown www-data:www-data /var/www/todos.txt

new string (str.OrderBy(c => c).ToArray())

I had the same problem, the solution is to add in build path/plugin the jar org.hamcrest.core_1xx, you can find it in eclipse/plugins.

I'm referring to TT's post and suggest the following approach:

Reference the System.Web dll in your model and use System.Web.Caching.Cache

public string[] GetNames()
{ 
    var noms = Cache["names"];
    if(noms == null) 
    {    
        noms = DB.GetNames();
        Cache["names"] = noms; 
    }

    return ((string[])noms);
}

You should not return a value re-read from the cache, since you'll never know if at that specific moment it is still in the cache. Even if you inserted it in the statement before, it might already be gone or has never been added to the cache - you just don't know.

So you add the data read from the database and return it directly, not re-reading from the cache.

For iOS you need to use the touchmove event as well as the scroll event like this:

document.addEventListener("touchmove", ScrollStart, false);
document.addEventListener("scroll", Scroll, false);

function ScrollStart() {
    //start of scroll event for iOS
}

function Scroll() {
    //end of scroll event for iOS
    //and
    //start/end of scroll event for other browsers
}

Those two replaceAll calls will always produce the same result, regardless of what x is. However, it is important to note that the two regular expressions are not the same:

• \\s - matches single whitespace character
• \\s+ - matches sequence of one or more whitespace characters.

In this case, it makes no difference, since you are replacing everything with an empty string (although it would be better to use \\s+ from an efficiency point of view). If you were replacing with a non-empty string, the two would behave differently.

Solution for Windows/msys git

After reading the answers, I discovered a simpler way that involves changing only one file.

1. Create a batch file to invoke your diff program, with argument 2 and 5. This file must be somewhere in your path. (If you don't know where that is, put it in c:\windows). Call it, for example, "gitdiff.bat". Mine is:

   @echo off
   REM This is gitdiff.bat
   "C:\Program Files\WinMerge\WinMergeU.exe" %2 %5
   

2. Set the environment variable to point to your batch file. For example:GIT_EXTERNAL_DIFF=gitdiff.bat. Or through powershell by typing git config --global diff.external gitdiff.bat.

   It is important to not use quotes, or specify any path information, otherwise it won't work. That's why gitdiff.bat must be in your path.

Now when you type "git diff", it will invoke your external diff viewer.

In addition to what @berguiga-mohamed-amine stated, I just found that a wildcard requires leaving the module argument the empty string:

compile ("com.github.jsonld-java:jsonld-java:$jsonldJavaVersion") {
    exclude group: 'org.apache.httpcomponents', module: ''
    exclude group: 'org.slf4j', module: ''
}

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

Try this:

.countTable table tr td:first-child + td

You could also reiterate in order to style the others columns:

.countTable table tr td:first-child + td + td {...} /* third column */
.countTable table tr td:first-child + td + td + td {...} /* fourth column */
.countTable table tr td:first-child + td + td + td +td {...} /* fifth column */

Kotlin supports type aliases https://kotlinlang.org/docs/reference/type-aliases.html. You can rename types and function types.

Running WinXP and I never seem to have time to kick off a defrag and wait for it to finish. So I wrote my own script to fire off XP's builtin defrag.exe and scheduled it to run nitely. The results are saved to a log file in C:\Temp for later review.

Programmatic formatting solution:

The JSON.stringify method supported by many modern browsers (including IE8) can output a beautified JSON string:

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level

Demo: http://jsfiddle.net/AndyE/HZPVL/

This method is also included with json2.js, for supporting older browsers.

Manual formatting solution

If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.

If you wish dialog box to be re-activated for the page you set as prevent dialog box to show.

Chrome: select settings, a google page for chrome will open with all your settings for chrome.

At the very bottom, go to advance settings and at the bottom of the advance settings you may click on Resset Browser Settings... this will make dialog box appear as they should.

Note :- Certainly in python-3x you need to use Range function It works to generate numbers on demand, standard method to use Range function to make a list of consecutive numbers is

x=list(range(10))
#"list"_will_make_all_numbers_generated_by_range_in_a_list
#number_in_range_(10)_is_an_option_you_can_change_as_you_want
print (x)
#Output_is_ [0,1,2,3,4,5,6,7,8,9]

Also if you want to make an function to generate a list of consecutive numbers by using Range function watch this code !

def  consecutive_numbers(n) :
    list=[i for i in range(n)]
    return (list)
print(consecutive_numbers(10))

Good Luck!

install exceljs and use the following code,

var Excel = require('exceljs');

var wb = new Excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'sample.xlsx');

wb.xlsx.readFile(filePath).then(function(){

    var sh = wb.getWorksheet("Sheet1");

    sh.getRow(1).getCell(2).value = 32;
    wb.xlsx.writeFile("sample2.xlsx");
    console.log("Row-3 | Cell-2 - "+sh.getRow(3).getCell(2).value);

    console.log(sh.rowCount);
    //Get all the rows data [1st and 2nd column]
    for (i = 1; i <= sh.rowCount; i++) {
        console.log(sh.getRow(i).getCell(1).value);
        console.log(sh.getRow(i).getCell(2).value);
    }
});

Why not use memset()? That's how to do it.

Setting the first element leaves the rest of the memory untouched, but str functions will treat the data as empty.

Pick up a copy of 'JavaScript design patterns' by Dustin Diaz. There's a few chapters dedicated to implementing JavaScript interfaces through Duck Typing. It's a nice read as well. But no, there's no language native implementation of an interface, you have to Duck Type.

// example duck typing method
var hasMethods = function(obj /*, method list as strings */){
    var i = 1, methodName;
    while((methodName = arguments[i++])){
        if(typeof obj[methodName] != 'function') {
            return false;
        }
    }
    return true;
}

// in your code
if(hasMethods(obj, 'quak', 'flapWings','waggle')) {
    //  IT'S A DUCK, do your duck thang
}

If you just want to remove single character and If you know index of a character you want to remove, you can use following function:

/**
 * Remove single character at particular index from string
 * @param {*} index index of character you want to remove
 * @param {*} str string from which character should be removed
 */
function removeCharAtIndex(index, str) {
    var maxIndex=index==0?0:index;
    return str.substring(0, maxIndex) + str.substring(index, str.length)
}

.NET and Mono are great environments, with many tools and and excellent skills base of people who know how to use them.

I think Mono has the opportunity to be the mobile cross-platform development environment of choice, seeing as they are the only alternative to Objective-C on the iPhone and should be portable to Android, and .NET is already on Windows Mobile.

I'm really hoping to see a solid implementation of Mono on Android, with wrappers for the Android API as with Monotouch, and would be prepared to pay for it since I'm not in a position to do it myself.

If you're using rails you can also use in_groups_of:

foo.in_groups_of(3)

Simply Use in Laravel Eloquent:

$a='foo', $b='bar', $c='john', $d='doe';

Coder::where(function ($query) use ($a, $b) {
    $query->where('a', '=', $a)
          ->orWhere('b', '=', $b);
})->where(function ($query) use ($c, $d) {
    $query->where('c', '=', $c)
          ->orWhere('d', '=', $d);
})->get();

Will produce a query like:

SELECT * FROM <table> WHERE (a='foo' or b='bar') AND (c='john' or d='doe');

The ternary operator can be included within an rvalue, whereas an if-then-else cannot; on the other hand, an if-then-else can execute loops and other statements, whereas the ternary operator can only execute (possibly void) rvalues.

On a related note, the && and || operators allow some execution patterns which are harder to implement with if-then-else. For example, if one has several functions to call and wishes to execute a piece of code if any of them fail, it can be done nicely using the && operator. Doing it without that operator will either require redundant code, a goto, or an extra flag variable.

The first few results on Google all sound like good options:

mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).

You type that command from a shell prompt.

Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:

FLUSH HOSTS;

Also, there is a nice demo that shows how can you use Angularjs animation in your project.

The link is here (See the top left corner).

It's an open source. Here is the link to download

And here is the link for tutorial;

My point is, go ahead and download the source files and then see how they have implemented the spinner. They might have used a little better aproach. So, checkout this project.

You can use the non-standard FROM clause.

UPDATE b
SET column1 = a.column1,
  column2 = a.column2,
  column3 = a.column3
FROM a
WHERE a.id = b.id
AND b.id = 1

I, too, have this problem on an older Mac that I upgraded to Lion.

Before reading the terminfo tip, I was able to get vi and less working by doing "export TERM=xterm".

After reading the tip, I grabbed /usr/share/terminfo from a newer Mac that has fresh install of Lion and does not exhibit this problem.

Now, even though echo $TERM still yields xterm-256color, vi and less now work fine.

First create table without auto_increment,

CREATE TABLE `members`(
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL
    PRIMARY KEY (memberid) 
) ENGINE = MYISAM;

after set id as index,

ALTER TABLE `members` ADD INDEX(`id`);

after set id as auto_increment,

ALTER TABLE `members` CHANGE `id` `id` INT(11) NOT NULL AUTO_INCREMENT;

Or

CREATE TABLE IF NOT EXISTS `members` (
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL,
      PRIMARY KEY (`memberid`),
      KEY `id` (`id`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

psql --pset=format=FORMAT

Great for executing queries from command line, e.g.

Since this question was originally asked, Google's Guava library now includes a powerful and flexible cache. I would recommend using this.

Use the Python list insert() method. Usage:

#Syntax

The syntax for the insert() method -

list.insert(index, obj)

#Parameters

• index - This is the Index where the object obj need to be inserted.
• obj - This is the Object to be inserted into the given list.

#Return Value This method does not return any value, but it inserts the given element at the given index.

Example:

a = [1,2,4,5]

a.insert(2,3)

print(a)

Returns [1, 2, 3, 4, 5]

Currently, only CMake is supported by CLion. Others build systems will be added in the future, but currently, you can only use CMake.

An importer tool has been implemented to help you to use CMake.

I second jdk's answer: any public static member of any class of your application can be considered as a "global variable".

However, do note that this is an ASP.NET application, and as such, it's a multi-threaded context for your global variables. Therefore, you should use some locking mechanism when you update and/or read the data to/from these variables. Otherwise, you might get your data in a corrupted state.

The easiest way:

add_compile_options(-std=c++11)

From the Finder menu, click Go->Go to Folder. Type in /Applications/XAMPP

It depends on what you want to test:

• for a string, you can use If strName = vbNullString or IF strName = "" or Len(strName) = 0 (last one being supposedly faster)
• for an object, you can use If myObject is Nothing
• for a recordset field, you could use If isnull(rs!myField)
• for an Excel cell, you could use If range("B3") = "" or IsEmpty(myRange)

Extended discussion available here (for Access, but most of it works for Excel as well).

Do you really need the image as a byte[]? What exactly do you expect in the byte[] - the complete content of an image file, encoded in whatever format the image file is in, or RGB pixel values?

Other answers here show you how to read a file into a byte[]. Your byte[] will contain the exact contents of the file, and you'd need to decode that to do anything with the image data.

Java's standard API for reading (and writing) images is the ImageIO API, which you can find in the package javax.imageio. You can read in an image from a file with just a single line of code:

BufferedImage image = ImageIO.read(new File("image.jpg"));

This will give you a BufferedImage, not a byte[]. To get at the image data, you can call getRaster() on the BufferedImage. This will give you a Raster object, which has methods to access the pixel data (it has several getPixel() / getPixels() methods).

Lookup the API documentation for javax.imageio.ImageIO, java.awt.image.BufferedImage, java.awt.image.Raster etc.

ImageIO supports a number of image formats by default: JPEG, PNG, BMP, WBMP and GIF. It's possible to add support for more formats (you'd need a plug-in that implements the ImageIO service provider interface).

Very simple stuff. Before returning the tableview Cell use the style property of the table view cell.

Try to use updated JMeter version which is JMeter 3.0 now.

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });
    });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

This may come a bit too late, but I have written something for this very purpose. My library will mock out the basic crud repository methods for you as well as interpret most of the functionalities of your query methods. You will have to inject functionalities for your own native queries, but the rest are done for you.

Take a look:

UPDATE

This is now in Maven central and in pretty good shape.

If you work with an iterator of conditions, it could be slow to access. But you don't need to access each element more than once, and you don't always need to read all of it. Here's a solution that will work with infinite generators:

#!/usr/bin/env python3
from random import randint
from itertools import tee

def generate_random():
    while True:
        yield bool(randint(0,1))

def any_but_not_all2(s): # elegant
    t1, t2 = tee(s)
    return False in t1 and True in t2 # could also use "not all(...) and any(...)"

def any_but_not_all(s): # simple
    hadFalse = False
    hadTrue = False
    for i in s:
        if i:
            hadTrue = True
        else:
            hadFalse = True
        if hadTrue and hadFalse:
            return True
    return False


r1, r2 = tee(generate_random())
assert any_but_not_all(r1)
assert any_but_not_all2(r2)

assert not any_but_not_all([True, True])
assert not any_but_not_all2([True, True])

assert not any_but_not_all([])
assert not any_but_not_all2([])

assert any_but_not_all([True, False])
assert any_but_not_all2([True, False])

This visualization can help us to find out difference between concept of element and tag (each indent means contain):

- element

        - content:

            - text 

            - other elements 

            - or empty

        - and its markup

            - tags (start or end tag)

                - element name

                - angle brackets < >

                - or attributes (just for start tag)

                - or slash / 

You can use scroll-behavior: smooth; to get this done without Javascript

By the time the query gets to SQL you have to have already expanded the list. The easy way of doing this, if you're using IDs from some internal, trusted data source, where you can be 100% certain they're integers (e.g., if you selected them from your database earlier) is this:

$sql = 'SELECT * WHERE id IN (' . implode(',', $ids) . ')';

If your data are coming from the user, though, you'll need to ensure you're getting only integer values, perhaps most easily like so:

$sql = 'SELECT * WHERE id IN (' . implode(',', array_map('intval', $ids)) . ')';

This is a simple way of doing something.

    @Override
        public void onBackPressed() {
            // do what you want to do when the "back" button is pressed.
            startActivity(new Intent(Activity.this, MainActivity.class));
            finish();
        }

I think there might be more elaborate ways of going about it, but I like simplicity. For example, I used the template above to make the user sign out of the application AND THEN go back to another activity of my choosing.

(Copied from this question)

In cases where I have not had control over the incoming JSON (and so cannot ensure that it includes a $type property) I have written a custom converter that just allows you to explicitly specify the concrete type:

public class Model
{
    [JsonConverter(typeof(ConcreteTypeConverter<Something>))]
    public ISomething TheThing { get; set; }
}

This just uses the default serializer implementation from Json.Net whilst explicitly specifying the concrete type.

An overview are available on this blog post. Source code is below:

public class ConcreteTypeConverter<TConcrete> : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        //assume we can convert to anything for now
        return true;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        //explicitly specify the concrete type we want to create
        return serializer.Deserialize<TConcrete>(reader);
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        //use the default serialization - it works fine
        serializer.Serialize(writer, value);
    }
}

try to use

word-wrap: break-word;

There's an easier solution for this, but it requires that you know exactly how much inheritance your current class has gone through. Fortunately, get_parent_class()'s arguments allow your class array member to be the class name as a string as well as an instance itself.

Bear in mind that this also inherently relies on calling a class' __construct() method statically, though within the instanced scope of an inheriting object the difference in this particular case is negligible (ah, PHP).

Consider the following:

class Foo {
    var $f = 'bad (Foo)';

    function __construct() {
        $this->f = 'Good!';
    }
}

class Bar extends Foo {
    var $f = 'bad (Bar)';
}

class FooBar extends Bar {
    var $f = 'bad (FooBar)';

    function __construct() {
        # FooBar constructor logic here
        call_user_func(array(get_parent_class(get_parent_class($this)), '__construct'));
    }
}

$foo = new FooBar();
echo $foo->f; #=> 'Good!'

Again, this isn't a viable solution for a situation where you have no idea how much inheritance has taken place, due to the limitations of debug_backtrace(), but in controlled circumstances, it works as intended.

I know this is old, but for those surfing this question, the answer by MUG4N will align all columns that use the same defaultcellstyle. I'm not using autogeneratecolumns so that is not acceptable. Instead I used:

e.Column.DefaultCellStyle = new DataGridViewCellStyle(e.Column.DefaultCellStyle);
e.Column.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

In this case e is from:

Grd_ColumnAdded(object sender, DataGridViewColumnEventArgs e)  

first, you need to load URL helper like this type or you can upload within autoload.php file:

$this->load->helper('url');

if (!$user_logged_in)
{
  redirect('/account/login', 'refresh');
}

Giving an element the attribute readonly will give that element the readonly status. It doesn't matter what value you put after it or if you put any value after it, it will still see it as readonly. Putting readonly="false" won't work.

Suggested is to use the W3C standard, which is readonly="readonly".

For anyone going through these issues and uneasy about disabling a whole set of checks, there is a way to pass your own custom signatures to Intelephense.

Copied from Intelephese repo's comment (by @KapitanOczywisty):
https://github.com/bmewburn/vscode-intelephense/issues/892#issuecomment-565852100

For single workspace it is very simple, you have to create .php file with all signatures and intelephense will index them.

If you want add stubs globally, you still can, but I'm not sure if it's intended feature. Even if intelephense.stubs throws warning about incorrect value you can in fact put there any folder name.

{   
   "intelephense.stubs": [
       // ...
       "/path/to/your/stub"   
   ] 
} 

Note: stubs are refreshed with this setting change.

You can take a look at build-in stubs here: https://github.com/JetBrains/phpstorm-stubs

In my case, I needed dspec's describe, beforeEach, it... to don't be highlighted as errors, so I just included the file with the signatures /directories_and_paths/app/vendor/bin/dspec in my VSCode's workspace settings, which had the function declarations I needed:

function describe($description = null, \Closure $closure = null) {
}

function it($description, \Closure $closure) {
}

// ... and so on

The only subquery appears to be this - try adding a ROWNUM limit to the where to be sure:

(SELECT C.I_WORKDATE
         FROM T_COMPENSATION C
         WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
         AND C.I_EMPID = A.I_EMPID)

You do need to investigate why this isn't unique, however - e.g. the employee might have had more than one C.I_COMPENSATEDDATE on the matched date.

For performance reasons, you should also see if the lookup subquery can be rearranged into an inner / left join, i.e.

 SELECT 
    ...
    REPLACE(TO_CHAR(C.I_WORKDATE, 'DD-Mon-YYYY'),
            ' ',
            '') AS WORKDATE,
    ...
 INNER JOIN T_EMPLOYEE_MS E
    ...
     LEFT OUTER JOIN T_COMPENSATION C
          ON C.I_COMPENSATEDDATE = A.I_REQDATE
          AND C.I_EMPID = A.I_EMPID
    ...

If you're using PhoneGap, then create a custom PhoneGap plugin:

Create a new class in your app's package:

package com.Demo; //replace with your package name

import org.json.JSONArray;

import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;

import com.phonegap.api.Plugin;
import com.phonegap.api.PluginResult;
import com.phonegap.api.PluginResult.Status;

public class PackageManagerPlugin extends Plugin {

    public final String ACTION_GET_VERSION_NAME = "GetVersionName";

    @Override
    public PluginResult execute(String action, JSONArray args, String callbackId) {
        PluginResult result = new PluginResult(Status.INVALID_ACTION);
        PackageManager packageManager = this.ctx.getPackageManager();

        if(action.equals(ACTION_GET_VERSION_NAME)) {
            try {
                PackageInfo packageInfo = packageManager.getPackageInfo(
                                              this.ctx.getPackageName(), 0);
                result = new PluginResult(Status.OK, packageInfo.versionName);
            }
            catch (NameNotFoundException nnfe) {
                result = new PluginResult(Status.ERROR, nnfe.getMessage());
            }
        }

        return result;
    }
}

In the plugins.xml, add the following line:

<plugin name="PackageManagerPlugin" value="com.Demo.PackageManagerPlugin" />

In your deviceready event, add the following code:

var PackageManagerPlugin = function() {

};
PackageManagerPlugin.prototype.getVersionName = function(successCallback, failureCallback) {
    return PhoneGap.exec(successCallback, failureCallback, 'PackageManagerPlugin', 'GetVersionName', []);
};
PhoneGap.addConstructor(function() {
    PhoneGap.addPlugin('packageManager', new PackageManagerPlugin());
});

Then, you can get the versionName attribute by doing:

window.plugins.packageManager.getVersionName(
    function(versionName) {
        //do something with versionName
    },
    function(errorMessage) {
        //do something with errorMessage
    }
);

Derived from here and here.

Heres a nicer way using closures

usort($your_data, function($a, $b)
{
    return strcmp($a->name, $b->name);
});

Please note this is not in PHP's documentation but if you using 5.3+ closures are supported where callable arguments can be provided.

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

playground

    byte[] seed = (SALT2 + username + password).getBytes();
    SecureRandom random = new SecureRandom(seed);
    KeyGenerator generator;
    generator = KeyGenerator.getInstance("AES");
    generator.init(random);
    generator.init(256);
    Key keyObj = generator.generateKey();

Use replace method.

String newWord = word.replace(String.valueOf(word.charAt(0)), String.valueOf(word.charAt(0)).toUpperCase());

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

list comprehension formula:

[<value_when_condition_true> if <condition> else <value_when_condition_false> for value in list_name]

thus you can do it like this:

[y for y in a if y not in b]

Only for demonstration purpose : [y if y not in b else False for y in a ]

bobince's answer will let you know in which cases "height: XX%;" will or won't work.

If you want to create an element with a set ratio (height: % of it's own width), the best way to do that is by effectively setting the height using padding-bottom. Example for square:

<div class="square-container">
  <div class="square-content">
    <!-- put your content in here -->
  </div>
</div>

.square-container {  /* any display: block; element */
  position: relative;
  height: 0;
  padding-bottom: 100%; /* of parent width */
}
.square-content {
  position: absolute;
  left: 0;
  top: 0;
  height: 100%;
  width: 100%;
}

The square container will just be made of padding, and the content will expand to fill the container. Long article from 2009 on this subject: http://alistapart.com/article/creating-intrinsic-ratios-for-video

This works on SQL Server 2008/2012/2014. Most of query comes from "sp_databases" system stored procedure. I only removed unneeded column and added where conditions.

This will select and deselect all checkboxes:

function checkAll()
{
     var checkboxes = document.getElementsByTagName('input'), val = null;    
     for (var i = 0; i < checkboxes.length; i++)
     {
         if (checkboxes[i].type == 'checkbox')
         {
             if (val === null) val = checkboxes[i].checked;
             checkboxes[i].checked = val;
         }
     }
 }

Demo

Update:

You can use querySelectAll directly on the table to get the list of checkboxes instead of searching the whole document, but It might not be compatible with old browsers so you need to check that first:

 function checkAll()
 {
     var table = document.getElementById ('dataTable');
     var checkboxes = table.querySelectorAll ('input[type=checkbox]');
     var val = checkboxes[0].checked;
     for (var i = 0; i < checkboxes.length; i++) checkboxes[i].checked = val;
 }

Or to be more specific for the provided html structure in the OP question, this would be more efficient when selecting the checkboxes as it will access them directly instead of searching for them:

function checkAll (tableID)
{
    var table = document.getElementById (tableID);
    var val = table.rows[0].cells[0].children[0].checked;
    for (var i = 1; i < table.rows.length; i++)
    {
        table.rows[i].cells[0].children[0].checked = val;
    }
}

Here's where the standard shortcut keys are covered:

http://wiki.eclipse.org/User_Interface_Guidelines#Standard_Accelerators

You'll find many of the more esoteric ones here:

http://wiki.eclipse.org/FAQ_What_editor_keyboard_shortcuts_are_available%3F

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

Override highlighted variable. Adding @IBInspectable makes you edit the highlighted backgroundColor in storyboard, which is nifty too.

class BackgroundHighlightedButton: UIButton {
    @IBInspectable var highlightedBackgroundColor :UIColor?
    @IBInspectable var nonHighlightedBackgroundColor :UIColor?
    override var highlighted :Bool {
        get {
            return super.highlighted
        }
        set {
            if newValue {
                self.backgroundColor = highlightedBackgroundColor
            }
            else {
                self.backgroundColor = nonHighlightedBackgroundColor
            }
            super.highlighted = newValue
        }
    }
}

It is possible.

For portability, one should probably use std::signal from the standard C++ library, but there is a lot of restriction on what a signal handler can do. Unfortunately, it is not possible to catch a SIGSEGV from within a C++ program without introducing undefined behavior because the specification says:

1. it is undefined behavior to call any library function from within the handler other than a very narrow subset of the standard library functions (abort, exit, some atomic functions, reinstall current signal handler, memcpy, memmove, type traits, `std::move, std::forward, and some more).
2. it is undefined behavior if handler use a throw expression.
3. it is undefined behavior if the handler returns when handling SIGFPE, SIGILL, SIGSEGV

This proves that it is impossible to catch SIGSEGV from within a program using strictly standard and portable C++. SIGSEGV is still caught by the operating system and is normally reported to the parent process when a wait family function is called.

You will probably run into the same kind of trouble using POSIX signal because there is a clause that says in 2.4.3 Signal Actions:

The behavior of a process is undefined after it returns normally from a signal-catching function for a SIGBUS, SIGFPE, SIGILL, or SIGSEGV signal that was not generated by kill(), sigqueue(), or raise().

A word about the longjumps. Assuming we are using POSIX signals, using longjump to simulate stack unwinding won't help:

Although longjmp() is an async-signal-safe function, if it is invoked from a signal handler which interrupted a non-async-signal-safe function or equivalent (such as the processing equivalent to exit() performed after a return from the initial call to main()), the behavior of any subsequent call to a non-async-signal-safe function or equivalent is undefined.

This means that the continuation invoked by the call to longjump cannot reliably call usually useful library function such as printf, malloc or exit or return from main without inducing undefined behavior. As such, the continuation can only do a restricted operations and may only exit through some abnormal termination mechanism.

To put things short, catching a SIGSEGV and resuming execution of the program in a portable is probably infeasible without introducing UB. Even if you are working on a Windows platform for which you have access to Structured exception handling, it is worth mentioning that MSDN suggest to never attempt to handle hardware exceptions: Hardware Exceptions.

At last but not least, whether any SIGSEGV would be raised when dereferencing a null valued pointer (or invalid valued pointer) is not a requirement from the standard. Because indirection through a null valued pointer or any invalid valued pointer is an undefined behaviour, which means the compiler assumes your code will never attempt such a thing at runtime, the compiler is free to make code transformation that would elide such undefined behavior. For example, from cppreference,

int foo(int* p) {
    int x = *p;
    if(!p)
        return x; // Either UB above or this branch is never taken
    else
        return 0;
}
 
int main() {
    int* p = nullptr;
    std::cout << foo(p);
}

Here the true path of the if could be completely elided by the compiler as an optimization; only the else part could be kept. Said otherwise, the compiler infers foo() will never receive a null valued pointer at runtime since it would lead to an undefined behaviour. Invoking it with a null valued pointer, you may observe the value 0 printed to standard output and no crash, you may observe a crash with SIGSEG, in fact you could observe anything since no sensible requirements are imposed on programs that are not free of undefined behaviors.

Dependent on how the API is created, normally with a 201 (created) you would return the resource which was created. For example if it was creating a user account you would do something like:

return {"data": {"username": "test","id":"fdsf345"}}, 201

Note the postfixed number is the status code returned.

Alternatively, you may want to send a message to the client such as:

return {"msg": "Created Successfully"}, 201

There is simpler method.

Instead of using setTimeout or working with socket directly,
We can use 'timeout' in the 'options' in client uses

Below is code of both server and client, in 3 parts.

Module and options part:

'use strict';

// Source: https://github.com/nodejs/node/blob/master/test/parallel/test-http-client-timeout-option.js

const assert = require('assert');
const http = require('http');

const options = {
    host: '127.0.0.1', // server uses this
    port: 3000, // server uses this

    method: 'GET', // client uses this
    path: '/', // client uses this
    timeout: 2000 // client uses this, timesout in 2 seconds if server does not respond in time
};

Server part:

function startServer() {
    console.log('startServer');

    const server = http.createServer();
    server
            .listen(options.port, options.host, function () {
                console.log('Server listening on http://' + options.host + ':' + options.port);
                console.log('');

                // server is listening now
                // so, let's start the client

                startClient();
            });
}

Client part:

function startClient() {
    console.log('startClient');

    const req = http.request(options);

    req.on('close', function () {
        console.log("got closed!");
    });

    req.on('timeout', function () {
        console.log("timeout! " + (options.timeout / 1000) + " seconds expired");

        // Source: https://github.com/nodejs/node/blob/master/test/parallel/test-http-client-timeout-option.js#L27
        req.destroy();
    });

    req.on('error', function (e) {
        // Source: https://github.com/nodejs/node/blob/master/lib/_http_outgoing.js#L248
        if (req.connection.destroyed) {
            console.log("got error, req.destroy() was called!");
            return;
        }

        console.log("got error! ", e);
    });

    // Finish sending the request
    req.end();
}


startServer();

If you put all the above 3 parts in one file, "a.js", and then run:

node a.js

then, output will be:

startServer
Server listening on http://127.0.0.1:3000

startClient
timeout! 2 seconds expired
got closed!
got error, req.destroy() was called!

Hope that helps.

One way I found that helps with this is to use \include{file_with_tex_figure_commands}

(not input)

Based on link you've provided, right answer should be

Math.floor(Math.random()*899999+100000);

Math.random() returns float between 0 and 1, so minimum number will be 100000, max - 999999. Exactly 6 digits, as you wanted :)

The JavaDoc explains it very well:

With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.

SO_TIMEOUT is the timeout that a read() call will block. If the timeout is reached, a java.net.SocketTimeoutException will be thrown. If you want to block forever put this option to zero (the default value), then the read() call will block until at least 1 byte could be read.

using (FileStream fs = File.OpenRead(binarySourceFile.Path))
    using (BinaryReader reader = new BinaryReader(fs))
    {              
        // Read in all pairs.
        while (reader.BaseStream.Position != reader.BaseStream.Length)
        {
            Item item = new Item();
            item.UniqueId = reader.ReadString();
            item.StringUnique = reader.ReadString();
            result.Add(item);
        }
    }
    return result;  

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

You can add a jar in Eclipse by right-clicking on the Project ? Build Path ? Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. A quick demo here.

The above solution is obviously a "Quick" one. However, if you are working on a project where you need to commit files to the source control repository, I would recommend adding Jar files to a dedicated library folder within your source control repository and referencing few or all of them as mentioned above.

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

There is an operator just for this. For example, if I wanted to change a variable i by 3 then:

var someValue = 9;
var Increment  = 3;
for(var i=0;i<someValue;i+=Increment){
//do whatever
}

var someValue = 3;
var Increment  = 3;
for(var i=9;i>someValue;i+=Increment){
//do whatever
}

You can use the following to get the root directory of a website project:

String FilePath;
FilePath = Server.MapPath("/MyWebSite");

Or you can get the base directory like so:

AppDomain.CurrentDomain.BaseDirectory

I feel that MWV (Model View Whatever) or MV* is a more flexible term to describe some of the uniqueness of Angularjs in my opinion. It helped me to understand that it is more than a MVC (Model View Controller) JavaScript framework, but it still uses MVC as it has a Model View, and Controller.

It also can be considered as a MVP (Model View Presenter) pattern. I think of a Presenter as the user-interface business logic in Angularjs for the View. For example by using filters that can format data for display. It's not business logic, but display logic and it reminds me of the MVP pattern I used in GWT.

In addition, it also can be a MVVM (Model View View Model) the View Model part being the two-way binding between the two. Last of all it is MVW as it has other patterns that you can use as well as mentioned by @Steve Chambers.

I agree with the other answers that getting pedantic on these terms can be detrimental, as the point is to understand the concepts from the terms, but by the same token, fully understanding the terms helps one when they are designing their application code, knowing what goes where and why.

Sometimes changing the date format doesn't work properly, especially in Laravel. So in that case, it's better to use:

$date1 = strtr($_REQUEST['date'], '/', '-');
echo date('Y-m-d', strtotime($date1));

Then you can avoid error like "1970-01-01"!

For those who use Notepad++ v6.8.1 and later, the auto-indent setting now is placed in menu Settings ? Preferences ? MISC. ? Auto Indent.

The above - findByBookIdRegion() did not work for me. The following works with the latest release of String Data JPA:

Page<QueuedBook> findByBookId_Region(Region region, Pageable pageable);

Another alternative is that you are allowed to have multiple classes in a tag. Consider:

 <div class="button big">This is a big button</div>
 <div class="button small">This is a small button</div>

And the CSS:

 .button {
     /* all your common button styles */
 }

 .big {
     height: 60px;
     width: 100px;
 }
 .small {
     height: 40px;
     width: 70px;
 }

and so on.

For browser close you can put below code into your web.config :

<system.web>
    <sessionState mode="InProc"></sessionState>
 </system.web>

It will destroy your session when browser is closed, but it will not work for tab close.

add this line end of php.ini

openssl.cafile=/opt/lampp/share/curl/curl-ca-bundle.crt

may be curl path cannot be identified by PHP

Be careful that when you using: curl -H "Authorization: token_str" http://www.example.com

token_str and Authorization must be separated by white space, otherwise server-side will not get the HTTP_AUTHORIZATION environment.

This can also occur if you have table arguments for things like 'aoColumns':[..] which don't match the correct number of columns. Problems like this can commonly occur when copy pasting code from other pages to quick start your datatables integration.

Example:

This won't work:

<table id="dtable">
    <thead>
        <tr>
            <th>col 1</th>
            <th>col 2</th>
        </tr>
    </thead>
    <tbody>
        <td>data 1</td>
        <td>data 2</td>
    </tbody>
</table>
<script>
        var dTable = $('#dtable');
        dTable.DataTable({
            'order': [[ 1, 'desc' ]],
            'aoColumns': [
                null,
                null,
                null,
                null,
                null,
                null,
                {
                    'bSortable': false
                }
            ]
        });
</script>

But this will work:

<table id="dtable">
    <thead>
        <tr>
            <th>col 1</th>
            <th>col 2</th>
        </tr>
    </thead>
    <tbody>
        <td>data 1</td>
        <td>data 2</td>
    </tbody>
</table>
<script>
        var dTable = $('#dtable');
        dTable.DataTable({
            'order': [[ 0, 'desc' ]],
            'aoColumns': [
                null,
                {
                    'bSortable': false
                }
            ]
        });
</script>

Matlab allows you to return multiple values as well as receive them inline.

When you call it, receive individual variables inline:

[array, listp, freep] = initialize(size)

In the new 2013 book named "Functional Programming Patterns- in Scala and Clojure" the author Michael.B. Linn does a decent job comparing and providing replacements in many cases for the GoF patterns and also discusses the newer functional patterns like 'tail recursion', 'memoization', 'lazy sequence', etc.

This book is available on Amazon. I found it very informative and encouraging when coming from an OO background of a couple of decades.

if hostname does not work, try IP address.

This is going on right now so I have to say. I try to ssh with my host name and it does not work

ssh [email protected]

this gives the error "ssh_exchange_identification: Connection closed by remote host"

this USED to work one hour back.

BUT, and here is the interesting part, the IP address works!

ssh [email protected]

(of course the actual IP address is different)

Go figure!

MySQL (before version 5.6.5) does not allow functions to be used for default DateTime values. TIMESTAMP is not suitable due to its odd behavior and is not recommended for use as input data. (See MySQL Data Type Defaults.)

That said, you can accomplish this by creating a Trigger.

I have a table with a DateCreated field of type DateTime. I created a trigger on that table "Before Insert" and "SET NEW.DateCreated=NOW()" and it works great.

I hope this helps somebody.

A good answer to this question should be succinct, handle unicode correctly, and deal with empty strings and nulls.

function isUpperCase(c) {
    return !!c && c != c.toLocaleLowerCase();
}

This approach deals with empty strings and nulls first, then ensures that converting the given string to lower case changes its equality. This ensures that the string contains at least one capital letter according to the current local's capitalisation rules (and won't return false positives for numbers and other glyphs that don't have capitalisation).

The original question asked specifically about testing the first character. In order to keep your code simple and clear I'd split the first character off the string separately from testing whether it's upper case.

With mockito you can use withSettings(), for example if the CounterService required 2 dependencies, you can pass them as a mock:

UserService userService = Mockito.mock(UserService.class); SearchService searchService = Mockito.mock(SearchService.class); CounterService counterService = Mockito.mock(CounterService.class, withSettings().useConstructor(userService, searchService));

FILE1 = /usr/bin/perl
FILE2 = /nofile

ifeq ($(shell test -e $(FILE1) && echo -n yes),yes)
    RESULT1=$(FILE1) exists.
else
    RESULT1=$(FILE1) does not exist.
endif

ifeq ($(shell test -e $(FILE2) && echo -n yes),yes)
    RESULT2=$(FILE2) exists.
else
    RESULT2=$(FILE2) does not exist.
endif

all:
    @echo $(RESULT1)
    @echo $(RESULT2)

execution results:

bash> make
/usr/bin/perl exists.
/nofile does not exist.

We can use ng-src but when ng-src's value became null, '' or undefined, ng-src will not work. So just use ng-if for this case:

http://jsfiddle.net/Hx7B9/299/

<div ng-app>
    <div ng-controller="AppCtrl"> 
        <a href='#'><img ng-src="{{link}}" ng-if="!!link"/></a>
        <button ng-click="changeLink()">Change Image</button>
    </div>
</div>

If someone still needs it (like I do).

The specified role_name must be a role that the current session user is a member of. https://www.postgresql.org/docs/10/sql-set-role.html

We need to make the current session user a member of the role:

create role myrole;
set role myrole;
grant myrole to myuser;
set role myrole;

produces:

Role ROLE created.


Error starting at line : 4 in command -
set role myrole
Error report -
ERROR: permission denied to set role "myrole"

Grant succeeded.


Role SET succeeded.

The expression

"" + i

leads to string conversion of i at runtime. The overall type of the expression is String. i is first converted to an Integer object (new Integer(i)), then String.valueOf(Object obj) is called. So it is equivalent to

"" + String.valueOf(new Integer(i));

Obviously, this is slightly less performant than just calling String.valueOf(new Integer(i)) which will produce the very same result.

The advantage of ""+i is that typing is easier/faster and some people might think, that it's easier to read. It is not a code smell as it does not indicate any deeper problem.

Based on answers from the community, there appear to be several ways that might solve this:

1. From the official FAQ and support forums and this answer, you may have have a firewall or proxy issue that is blocking RStudio from connecting to the internet:

• Disable any firewalls
• Tools -> Global Options -> Packages and unchecking the "Use Internet Explorer library/proxy for HTTP" option and restart R (#1, #2, #3)
• Flag R with --internet2
• On CentOS it was suggested to try the following: install.packages('package_name', dependencies=TRUE, repos='http://cran.rstudio.com/')

2. Several answers suggest using an alternate mirror (#1, #2, #3):

• Preferences > General > Default working directory > Browse and switch your mirror from local/global (whichever is unchecked)

3. On Windows you can start the application with http_proxy=http://host:port/:

• "C:\Program Files\RStudio\bin\rstudio.exe" http_proxy=http://host:port/

5. Shut down and restart. Needed after many of the above operations, and suggested standalone.

Run SDK Manager as Admin will solve your problem

It can be done with the regular JavaScript function replace().

value.replace(".", ":");

If you want your value to be read by MVT controller when you submit the form and you don't what to deal with hidden inputs. What you can do is add value attribute to your checkbox and set it to true or false.

MVT will not recognize viewModel property myCheckbox as true here

<input type="checkbox" name="myCheckbox" checked="checked" />

but will if you add

<input type="checkbox" name="myCheckbox" checked="checked" value="true" />

Script that does it:

$(document).on("click", "[type='checkbox']", function(e) {
        if (this.checked) {
            $(this).attr("value", "true");
        } else {
            $(this).attr("value","false");}
    });

I have had good experiences with Rational Purify. I have also heard nice things about Valgrind

If the program you're using to execute your script needs parameters, you can put them at the end of the #! line:

#!/usr/bin/R --random --switches --f

Not knowing R, I can't test properly, but this seems to work:

axa@artemis:~$ cat r.test
#!/usr/bin/R -q -f
error
axa@artemis:~$ ./r.test
> #!/usr/bin/R -q -f
> error
Error: object "error" not found
Execution halted
axa@artemis:~$

There is one issue with the top voted answer here which recommends this regex:

/^[a-z ,.'-]+$/i

It takes spaces only as a valid name!

The best solution in my opinion is to add a negative look forward to the beginning:

^(?!\s)([a-z ,.'-]+)$/i

A clean way to delete a cookie is to clear both of $_COOKIE value and browser cookie file :

if (isset($_COOKIE['key'])) {
    unset($_COOKIE['key']);
    setcookie('key', '', time() - 3600, '/'); // empty value and old timestamp
}

From http://docs.python.org/library/csv.html#csv.writer:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with statement to close the file when you're done writing to it.
Tested example below:

from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']
with open('file3.csv','wb') as fou: # note: 'wb' instead of 'w'
    output = csv.DictWriter(fou,delimiter=',',fieldnames=headers)
    output.writerow(dict((fn,fn) for fn in headers))
    output.writerows(rows)

I like the answer of coin. It's simple to understand and works with triangles. However the indexes of his program are sometimes over the bounds. So I post here his code with two tiny corrections:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;
    int nextS = (s+1) % sectors;

If you understand stack very well then you will understand how memory works in program and if you understand how memory works in program you will understand how function store in program and if you understand how function store in program you will understand how recursive function works and if you understand how recursive function works you will understand how compiler works and if you understand how compiler works your mind will works as compiler and you will debug any program very easily

Let me explain how stack works:

First you have to know how functions are represented in stack :

Heap stores dynamically allocated values.
Stack stores automatic allocation and deletion values.

Let's understand with example :

def hello(x):
    if x==1:
        return "op"
    else:
        u=1
        e=12
        s=hello(x-1)
        e+=1
        print(s)
        print(x)
        u+=1
    return e

hello(4)

Now understand parts of this program :

Now let's see what is stack and what are stack parts:

Allocation of the stack :

Remember one thing: if any function's return condition gets satisfied, no matter it has loaded the local variables or not, it will immediately return from stack with it's stack frame. It means that whenever any recursive function get base condition satisfied and we put a return after base condition, the base condition will not wait to load local variables which are located in the “else” part of program. It will immediately return the current frame from the stack following which the next frame is now in the activation record.

See this in practice:

Deallocation of the block:

So now whenever a function encounters return statement, it delete the current frame from the stack.

While returning from the stack, values will returned in reverse of the original order in which they were allocated in stack.

I stumbled on this question while trying to do the same thing (I think). Here is how I did it:

df['index_col'] = df.index

You can then sort on the new index column, if you like.

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

just give

a{
color:blue
}

even if its is visited it will always be blue

I make a variation to generate this out from script:

volume C: - 49 GB total space / 29512314880 byte(s) free

I use diskpart to get this information.

@echo off
setlocal enableextensions enabledelayedexpansion
set chkfile=drivechk.tmp
if "%1" == "" goto :usage
set drive=%1
set drive=%drive:\=%
set drive=%drive::=%
dir %drive%:>nul 2>%chkfile%
for %%? in (%chkfile%) do (
  set chksize=%%~z?
)
if %chksize% neq 0 (
  more %chkfile%
  del %chkfile%
  goto :eof
)
del %chkfile%
echo list volume | diskpart | find /I " %drive% " >%chkfile%
for /f "tokens=6" %%a in ('type %chkfile%' ) do (
    set dsksz=%%a
)
for /f "tokens=7" %%a in ('type %chkfile%' ) do (
    set dskunit=%%a
)
del %chkfile%
for /f "tokens=3" %%a in ('dir %drive%:\') do (
  set bytesfree=%%a
)
set bytesfree=%bytesfree:,=%
echo volume %drive%: - %dsksz% %dskunit% total space / %bytesfree% byte(s) free
endlocal

goto :eof
:usage
  echo.
  echo   usage: freedisk ^<driveletter^> (eg.: freedisk c)

Assuming these were datetime columns (if they're not apply to_datetime) you can just subtract them:

df['A'] = pd.to_datetime(df['A'])
df['B'] = pd.to_datetime(df['B'])

In [11]: df.dtypes  # if already datetime64 you don't need to use to_datetime
Out[11]:
A    datetime64[ns]
B    datetime64[ns]
dtype: object

In [12]: df['A'] - df['B']
Out[12]:
one   -58 days
two   -26 days
dtype: timedelta64[ns]

In [13]: df['C'] = df['A'] - df['B']

In [14]: df
Out[14]:
             A          B        C
one 2014-01-01 2014-02-28 -58 days
two 2014-02-03 2014-03-01 -26 days

Note: ensure you're using a new of pandas (e.g. 0.13.1), this may not work in older versions.

Minimal example

And just to make what Mizux said as a minimal example:

main_c.c

#include <stdio.h>

int main(void) {
    puts("hello");
}

main_cpp.cpp

#include <iostream>

int main(void) {
    std::cout << "hello" << std::endl;
}

Then, without any Makefile:

make CFLAGS='-g -O3' \
     CXXFLAGS='-ggdb3 -O0' \
     CPPFLAGS='-DX=1 -DY=2' \
     CCFLAGS='--asdf' \
     main_c \
     main_cpp

runs:

cc -g -O3 -DX=1 -DY=2   main_c.c   -o main_c
g++ -ggdb3 -O0 -DX=1 -DY=2   main_cpp.cpp   -o main_cpp

So we understand that:

• make had implicit rules to make main_c and main_cpp from main_c.c and main_cpp.cpp
• CFLAGS and CPPFLAGS were used as part of the implicit rule for .c compilation
• CXXFLAGS and CPPFLAGS were used as part of the implicit rule for .cpp compilation
• CCFLAGS is not used

Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:

main_c: main_c.c
    $(CC) $(CFLAGS) $(CPPFLAGS) -o $@ $<

main_cpp: main_c.c
    $(CXX) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

to achieve a similar affect to the implicit rules.

We could also name those variables however we want: but since Make already treats them magically in the implicit rules, those make good name choices.

Tested in Ubuntu 16.04, GNU Make 4.1.

The ng-dirty class tells you that the form has been modified by the user, whereas the ng-pristine class tells you that the form has not been modified by the user. So ng-dirty and ng-pristine are two sides of the same story.

The classes are set on any field, while the form has two properties, $dirty and $pristine.

You can use the $scope.form.$setPristine() function to reset a form to pristine state (please note that this is an AngularJS 1.1.x feature).

If you want a $scope.form.$setPristine()-ish behavior even in 1.0.x branch of AngularJS, you need to roll your own solution (some pretty good ones can be found here). Basically, this means iterating over all form fields and setting their $dirty flag to false.

Hope this helps.

In one of our API project we decide to set a 409 Status to some request, when we can't full fill it at 100% because of missing parameter.

HTTP Status Code "409 Conflict" was for us a good try because it's definition require to include enough information for the user to recognize the source of the conflict.

Reference: w3.org/Protocols/

So among other response like 400 or 404 we chose 409 to enforce the need for looking over some notes in the request helpful to set up a new and right request.

Any way our case it was particular because we need to send out some data eve if the request was not completely correct, and we need to enforce the client to look at the message and understand what was wrong in the request.

In general if we have only some missing parameter we go for a 400 and an array of missing parameter. But when we need to send some more information, like a particular case message and we want to be more sure the client will take care of it we send a 409

You simply need to remove v-bind (:) from selected and required attributes. Like this :-

<template>_x000D_
    <select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
        <option selected>Choose Province</option>_x000D_
        <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
    </select>_x000D_
</template>

You are not binding anything to the vue instance through these attributes thats why it is giving error.

1. Declare object of EditText on top of class:

    EditText myEditText;
   

2. Find EditText in onCreate Function and setOnFocusChangeListener of EditText:

   myEditText = findViewById(R.id.yourEditTextNameInxml); 
   
   myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
               @Override
               public void onFocusChange(View view, boolean hasFocus) {
                   if (!hasFocus) {
                        Toast.makeText(this, "Focus Lose", Toast.LENGTH_SHORT).show();
                   }else{
                       Toast.makeText(this, "Get Focus", Toast.LENGTH_SHORT).show();
                   }
   
               }
           });
   

It works fine.

There are some caveats when it comes to CORS. First, it does not allow wildcards * but don't hold me on this one I've read it somewhere and I can't find the article now.

If you are making requests from a different domain you need to add the allow origin headers.

 Access-Control-Allow-Origin: www.other.com 

If you are making requests that affect server resources like POST/PUT/PATCH, and if the mime type is different than the following application/x-www-form-urlencoded, multipart/form-data, or text/plain the browser will automatically make a pre-flight OPTIONS request to check with the server if it would allow it.

So your API/server needs to handle these OPTIONS requests accordingly, you need to respond with the appropriate access control headers and the http response status code needs to be 200.

The headers should be something like this, adjust them for your needs:

   Access-Control-Allow-Methods: GET, POST, PUT, PATCH, POST, DELETE, OPTIONS
   Access-Control-Allow-Headers: Content-Type
   Access-Control-Max-Age: 86400

The max-age header is important, in my case, it wouldn't work without it, I guess the browser needs the info for how long the "access rights" are valid.

In addition, if you are making e.g. a POST request with application/json mime from a different domain you also need to add the previously mentioned allow origin header, so it would look like this:

   Access-Control-Allow-Origin: www.other.com 
   Access-Control-Allow-Methods: GET, POST, PUT, PATCH, POST, DELETE, OPTIONS
   Access-Control-Allow-Headers: Content-Type
   Access-Control-Max-Age: 86400

When the pre-flight succeeds and gets all the needed info your actual request will be made.

Generally speaking, whatever Access-Control headers are requested in the initial or pre-flight request, should be given in the response in order for it to work.

There is a good example in the MDN docs here on this link, and you should also check out this SO post

CharAt function not working

Edittext.setText(YourString.toCharArray(),0,1);

This code working fine

This will occur in SQL Server as well if you don't run all of the statements at once. If you are highlighting a set of statements and executing the following:

DECLARE @LoopVar INT
SET @LoopVar = (SELECT COUNT(*) FROM SomeTable)

And then try to highlight another set of statements such as:

PRINT 'LoopVar is: ' + CONVERT(NVARCHAR(255), @LoopVar)

You will receive this error.

You can do :

df['industry'] = 'yyy'

I'd try something like:

#!/usr/bin/python
from __future__ import print_function

import shlex
from subprocess import Popen, PIPE

def shlep(cmd):
    '''shlex split and popen
    '''
    parsed_cmd = shlex.split(cmd)
    ## if parsed_cmd[0] not in approved_commands:
    ##    raise ValueError, "Bad User!  No output for you!"
    proc = Popen(parsed_command, stdout=PIPE, stderr=PIPE)
    out, err = proc.communicate()
    return (proc.returncode, out, err)

... In other words let shlex.split() do most of the work. I would NOT attempt to parse the shell's command line, find pipe operators and set up your own pipeline. If you're going to do that then you'll basically have to write a complete shell syntax parser and you'll end up doing an awful lot of plumbing.

Of course this raises the question, why not just use Popen with the shell=True (keyword) option? This will let you pass a string (no splitting nor parsing) to the shell and still gather up the results to handle as you wish. My example here won't process any pipelines, backticks, file descriptor redirection, etc that might be in the command, they'll all appear as literal arguments to the command. Thus it is still safer then running with shell=True ... I've given a silly example of checking the command against some sort of "approved command" dictionary or set --- through it would make more sense to normalize that into an absolute path unless you intend to require that the arguments be normalized prior to passing the command string to this function.

First things first, if the date property is storing a date, store it using a DateTime. If you parse the date through the sort you have to parse it for each item being compared, that's not very efficient...

You can then make an IComparer:

public class TagComparer : IComparer<cTag>
{
    public int Compare(cTag first, cTag second)
    {
        if (first != null && second != null)
        {
            // We can compare both properties.
            return first.date.CompareTo(second.date);
        }

        if (first == null && second == null)
        {
            // We can't compare any properties, so they are essentially equal.
            return 0;
        }

        if (first != null)
        {
            // Only the first instance is not null, so prefer that.
            return -1;
        }

        // Only the second instance is not null, so prefer that.
        return 1;
    }
}

var list = new List<cTag>();
// populate list.

list.Sort(new TagComparer());

You can even do it as a delegate:

list.Sort((first, second) =>
          {
              if (first != null && second != null)
                  return first.date.CompareTo(second.date);

              if (first == null && second == null)
                  return 0;

              if (first != null)
                  return -1;

              return 1;
          });

EDIT: Sorry, I zipped past your question too quick. I realize now that you're looking for a list with the port name + port description. I've updated the code accordingly...

Using System.Management, you can query for all the ports, and all the information for each port (just like Device Manager...)

Sample code (make sure to add reference to System.Management):

using System;
using System.Management;
using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;        

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var searcher = new ManagementObjectSearcher
                ("SELECT * FROM WIN32_SerialPort"))
            {
                string[] portnames = SerialPort.GetPortNames();
                var ports = searcher.Get().Cast<ManagementBaseObject>().ToList();
                var tList = (from n in portnames
                            join p in ports on n equals p["DeviceID"].ToString()
                            select n + " - " + p["Caption"]).ToList();

                tList.ForEach(Console.WriteLine);
            }

            // pause program execution to review results...
            Console.WriteLine("Press enter to exit");
            Console.ReadLine();
        }
    }
}

It may help to use a different constructor for Uri.

If you have the server name

string server = "http://www.myserver.com";

and have a relative Uri path to append to it, e.g.

string relativePath = "sites/files/images/picture.png"

When creating a Uri from these two I get the "format could not be determined" exception unless I use the constructor with the UriKind argument, i.e.

// this works, because the protocol is included in the string
Uri serverUri = new Uri(server);

// needs UriKind arg, or UriFormatException is thrown
Uri relativeUri = new Uri(relativePath, UriKind.Relative); 

// Uri(Uri, Uri) is the preferred constructor in this case
Uri fullUri = new Uri(serverUri, relativeUri);

Comparison expressions should each be in their own brackets:

{% if (a == 'foo') or (b == 'bar') %}
    ...
{% endif %}

Alternative if you are inspecting a single variable and a number of possible values:

{% if a in ['foo', 'bar', 'qux'] %}
    ...
{% endif %}

Empty strings and nulls are fundamentally different. A null is an absence of a value and an empty string is a value that is empty.

The programming language making assumptions about the "value" of a variable, in this case an empty string, will be as good as initiazing the string with any other value that will not cause a null reference problem.

Also, if you pass the handle to that string variable to other parts of the application, then that code will have no ways of validating whether you have intentionally passed a blank value or you have forgotten to populate the value of that variable.

Another occasion where this would be a problem is when the string is a return value from some function. Since string is a reference type and can technically have a value as null and empty both, therefore the function can also technically return a null or empty (there is nothing to stop it from doing so). Now, since there are 2 notions of the "absence of a value", i.e an empty string and a null, all the code that consumes this function will have to do 2 checks. One for empty and the other for null.

In short, its always good to have only 1 representation for a single state. For a broader discussion on empty and nulls, see the links below.

https://softwareengineering.stackexchange.com/questions/32578/sql-empty-string-vs-null-value

NULL vs Empty when dealing with user input

This is not an plus, but the sign for the binary operator XOR

a   b   a XOR b
0   0   0
0   1   1
1   0   1
1   1   0

(untested) something like this may do the job

WITH
base AS
(
    select *                   -- get the table
    from sometable
    order by name              -- in the desired order
),
twenty AS
(
    select *                   -- get the first 30 rows
    from base
    where rownum < 30
    order by name              -- in the desired order
)
select *                       -- then get rows 21 .. 30
from twenty
where rownum > 20
order by name                  -- in the desired order

There is also the analytic function rank, that you can use to order by.

def prepare_table_row(row):
    lst = [i.text for i in row if i != u'\n']
    return dict(rank = int(lst[0]),
                grade = str(lst[1]),
                channel=str(lst[2])),
                videos = float(lst[3].replace(",", " ")),
                subscribers = float(lst[4].replace(",", "")),
                views = float(lst[5].replace(",", "")))

For this thing you can use @property as an decorator, so you could use instance methods as attributes. For example:

class Word_Parser:
    def __init__(self, sentences):
        self.sentences = sentences

    @property
    def parser(self):
        self.word_list = self.sentences.split()

    @property
    def sort_word_list(self):
        self.sorted_word_list = self.word_list.sort()

    @property
    def num_words(self):
        self.num_words = len(self.word_list)

test = Word_Parser("mary had a little lamb")
test.parser()
test.sort_word_list()
test.num_words()
print test.word_list
print test.sort_word_list
print test.num_words

so you can use access the attributes without calling (i.e., without the ()).

This is is the same as a weighted average problem where all the weights are the same, and there are two dimensions.

Find the average of all latitudes for your center latitude and the average of all longitudes for the center longitude.

Caveat Emptor: This is a close distance approximation and the error will become unruly when the deviations from the mean are more than a few miles due to the curvature of the Earth. Remember that latitudes and longitudes are degrees (not really a grid).

Add System.ServiceModel in references

Using SyndicationFeed:

string url = "http://fooblog.com/feed";
XmlReader reader = XmlReader.Create(url);
SyndicationFeed feed = SyndicationFeed.Load(reader);
reader.Close();
foreach (SyndicationItem item in feed.Items)
{
    String subject = item.Title.Text;    
    String summary = item.Summary.Text;
    ...                
}

One way I would do this without javascript would be to add a set of radio buttons that define the action to be taken:

• Update
• Delete
• Whatever

Then the action script would take different actions depending on the value of the radio button set.

Another way would be to put two forms on the page as you suggested, just not nested. The layout may be difficult to control though:

<form name="editform" action="the_action_url"  method="post">
   <input type="hidden" name="task" value="update" />
   <input type="text" name="foo" />
   <input type="submit" name="save" value="Save" />
</form>

<form name="delform" action="the_action_url"  method="post">
   <input type="hidden" name="task" value="delete" />
   <input type="hidden" name="post_id" value="5" />
   <input type="submit" name="delete" value="Delete" />
</form>

Using the hidden "task" field in the handling script to branch appropriately.

This only works on Windows, so if you are planning to use dotnet core cross-platform, you'll have to look elsewhere. See https://github.com/dotnet/corefx/blob/master/Documentation/architecture/cross-platform-cryptography.md

You need to call event.persist(); this method on your keyPress event. Example:

const MyComponent = (props) => {
   const keyboardEvents = (event) =>{
       event.persist();
       console.log(event.key); // this will return string of key name like 'Enter'
   }
   return(
         <div onKeyPress={keyboardEvents}></div>
   )
}

If you now type console.log(event) in keyboardEvents function you will get other attributes like:

keyCode // number
charCode // number
shiftKey // boolean
ctrlKey // boolean
altKey // boolean

And many other attributes

Jon has the right answer, but to elaborate a little more with some syntactic sugar..

SET | more

enables you to see the variables one page at a time, rather than the whole lot, or

SET > output.txt

sends the output to a file output.txt which you can open in Notepad or whatever...

Code check:

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

Bitwise operators are operators that work on multi-bit values, but conceptually one bit at a time.

• AND is 1 only if both of its inputs are 1, otherwise it's 0.
• OR is 1 if one or both of its inputs are 1, otherwise it's 0.
• XOR is 1 only if exactly one of its inputs are 1, otherwise it's 0.
• NOT is 1 only if its input is 0, otherwise it's 0.

These can often be best shown as truth tables. Input possibilities are on the top and left, the resultant bit is one of the four (two in the case of NOT since it only has one input) values shown at the intersection of the inputs.

AND | 0 1     OR | 0 1     XOR | 0 1    NOT | 0 1
----+-----    ---+----     ----+----    ----+----
 0  | 0 0      0 | 0 1       0 | 0 1        | 1 0
 1  | 0 1      1 | 1 1       1 | 1 0

One example is if you only want the lower 4 bits of an integer, you AND it with 15 (binary 1111) so:

    201: 1100 1001
AND  15: 0000 1111
------------------
 IS   9  0000 1001

The zero bits in 15 in that case effectively act as a filter, forcing the bits in the result to be zero as well.

In addition, >> and << are often included as bitwise operators, and they "shift" a value respectively right and left by a certain number of bits, throwing away bits that roll of the end you're shifting towards, and feeding in zero bits at the other end.

So, for example:

1001 0101 >> 2 gives 0010 0101
1111 1111 << 4 gives 1111 0000

Note that the left shift in Python is unusual in that it's not using a fixed width where bits are discarded - while many languages use a fixed width based on the data type, Python simply expands the width to cater for extra bits. In order to get the discarding behaviour in Python, you can follow a left shift with a bitwise and such as in an 8-bit value shifting left four bits:

bits8 = (bits8 << 4) & 255

With that in mind, another example of bitwise operators is if you have two 4-bit values that you want to pack into an 8-bit one, you can use all three of your operators (left-shift, and and or):

packed_val = ((val1 & 15) << 4) | (val2 & 15)

• The & 15 operation will make sure that both values only have the lower 4 bits.
• The << 4 is a 4-bit shift left to move val1 into the top 4 bits of an 8-bit value.
• The | simply combines these two together.

If val1 is 7 and val2 is 4:

                val1            val2
                ====            ====
 & 15 (and)   xxxx-0111       xxxx-0100  & 15
 << 4 (left)  0111-0000           |
                  |               |
                  +-------+-------+
                          |
| (or)                0111-0100

Use count(*)

declare 
   cnt integer;
begin
  SELECT count(*) INTO cnt
  FROM people
  WHERE person_id = my_person_id;

IF cnt > 0 THEN
  -- Do something
END IF;

Edit (for the downvoter who didn't read the statement and others who might be doing something similar)

The solution is only effective because there is a where clause on a column (and the name of the column suggests that its the primary key - so the where clause is highly effective)

Because of that where clause there is no need to use a LIMIT or something else to test the presence of a row that is identified by its primary key. It is an effective way to test this.

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.

Another way of converting between pretty much any data format using R is with the rio package.

• Install R from CRAN and open R
• Install the rio package using install.packages("rio")

• Load the rio library, then use the convert() function:

  library("rio")
  convert("my_file.dta", "my_file.csv")
  

This method allows you to convert between many formats (e.g., Stata, SPSS, SAS, CSV, etc.). It uses the file extension to infer format and load using the appropriate importing package. More info can be found on the R-project rio page.

<ComboBox Text="Something">
            <ComboBoxItem Content="Item1"></ComboBoxItem >
            <ComboBoxItem Content="Item2"></ComboBoxItem >
            <ComboBoxItem Content="Item3"></ComboBoxItem >
</ComboBox>

You either have to declare public $timestamps = false; in every model, or create a BaseModel, define it there, and have all your models extend it instead of eloquent. Just bare in mind pivot tables MUST have timestamps if you're using Eloquent.

Update: Note that timestamps are no longer REQUIRED in pivot tables after Laravel v3.

Update: You can also disable timestamps by removing $table->timestamps() from your migration.

You can do this in Kotlin by creating a class that extends Application and then use its context to call the resources anywhere in your code

Your App class will look like this

 class App : Application() {
    override fun onCreate() {
        super.onCreate()
        context = this
    }

    companion object {
        var context: Context? = null
            private set
    }
}

Declare your Application class in AndroidManifest.xml (very important)

<application
        android:allowBackup="true"
        android:name=".App" //<--Your declaration Here
        ...>
        <activity
            android:name=".SplashActivity"  android:theme="@style/SplashTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <activity android:name=".MainActivity"/>
    </application>

To access e.g. a string file use the following code

App.context?.resources?.getText(R.string.mystring)

You can't inject content from another site (domain) using AJAX. The reason an iFrame is suited for these kinds of things is that you can specify the source to be from another domain.

ls -alR|awk '{ if ($5 > max) {max=$5;ff=$9}} END {print max "\t" ff;}'

1800 INFORMATION is more or less correct, but there are a few issues I wanted to correct.

boost::shared_mutex _access;
void reader()
{
  boost::shared_lock< boost::shared_mutex > lock(_access);
  // do work here, without anyone having exclusive access
}

void conditional_writer()
{
  boost::upgrade_lock< boost::shared_mutex > lock(_access);
  // do work here, without anyone having exclusive access

  if (something) {
    boost::upgrade_to_unique_lock< boost::shared_mutex > uniqueLock(lock);
    // do work here, but now you have exclusive access
  }

  // do more work here, without anyone having exclusive access
}

void unconditional_writer()
{
  boost::unique_lock< boost::shared_mutex > lock(_access);
  // do work here, with exclusive access
}

Also Note, unlike a shared_lock, only a single thread can acquire an upgrade_lock at one time, even when it isn't upgraded (which I thought was awkward when I ran into it). So, if all your readers are conditional writers, you need to find another solution.

Use any examples that don't insert each element one at a time, one insertion is most efficient

 $('.element').html( '<span>' + array.join('</span><span>')+'</span>');

Most modern devices support the tel: scheme. So use <a href="tel:555-555-5555">555-555-5555</a> and you should be good to go.

If you want to use it for an image, the <a> tag can handle the <img/> placed in it just like other normal situations with : <a href="tel:555-555-5555"><img src="path/to/phone/icon.jpg" /></a>

You cannot detect if a key is down after it's been pressed. You can only monitor key events in js. In your case I'd suggest changing onclick with a key press event and then detecting if it's the control key by event keycode, and then you can add your click event.

Put this code in the <head></head> tags:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>

Set this in the constructor:

public class SearchModel
{
    public bool IsMale { get; set; }
    public bool IsFemale { get; set; }

    public SearchModel()
    { 
        IsMale = true;
        IsFemale = true;
    }
}

Then pass it to the view in your GET action:

[HttpGet]
public ActionResult Search()
{
    return new View(new SearchModel());
}

Here is the optimised solution in Swift5, including handling the wrong indexPath. - Michael Lin Liu

• Step1. Get the indexPath of the current cell.
• Step2. Detect the velocity when scroll.
• Step3. Increase the indexPath's row when the velocity is increased.
• Step4. Tell the collection view to scroll to the next item

    func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
        
        targetContentOffset.pointee = scrollView.contentOffset
        
        //M: Get the first visiable item's indexPath from visibaleItems.
        var indexPaths = *YOURCOLLECTIONVIEW*.indexPathsForVisibleItems
        indexPaths.sort()
        var indexPath = indexPaths.first!

        //M: Use the velocity to detect the paging control movement.
        //M: If the movement is forward, then increase the indexPath.
        if velocity.x > 0{
            indexPath.row += 1
            
            //M: If the movement is in the next section, which means the indexPath's row is out range. We set the indexPath to the first row of the next section.
            if indexPath.row == *YOURCOLLECTIONVIEW*.numberOfItems(inSection: indexPath.section){
                indexPath.row = 0
                indexPath.section += 1
            }
        }
        else{
            //M: If the movement is backward, the indexPath will be automatically changed to the first visiable item which is indexPath.row - 1. So there is no need to write the logic.
        }
        
        //M: Tell the collection view to scroll to the next item.
        *YOURCOLLECTIONVIEW*.scrollToItem(at: indexPath, at: .left, animated: true )
 }

Here is a simple if/else check in underscore.js, if you need to include a null check.

<div class="editor-label">
    <label>First Name : </label>
</div>
<div class="editor-field">
    <% if(FirstName == null) { %>
        <input type="text" id="txtFirstName" value="" />
    <% } else { %>
        <input type="text" id="txtFirstName" value="<%=FirstName%>" />
    <% } %>
</div>

To do it without VS2010 installation, and only 2012, set the msvs_version flag:

node-gyp rebuild --msvs_version=2012

npm install <module> --msvs_version=2012

as per @Jacob comment

npm install --msvs_version=2013 if you have the 2013 version

Use the following:

echo $form->field($model, 'hidden1')->hiddenInput(['value'=> $value])->label(false);

Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.

curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' \
     http://example.com/service

Using the exact JSON data from the question, the full command line would become:

curl -H 'Content-Type: application/json' -X PUT \
    -d '{"tags":["tag1","tag2"],
         "question":"Which band?",
         "answers":[{"id":"a0","answer":"Answer1"},
                    {"id":"a1","answer":"answer2"}]}' \
    http://example.com/service

Note: JSON data wrapped only for readability, not valid for curl request.

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

Check the settings of the browser proxy . For me it helped , traffic was directed outside.

i entered in Mysql Workbench and i changed the password. It seem the password was expired. it works!

In a couple of experiments in my masters thesis (e.g. page 59), I found that the bias might be important for the first layer(s), but especially at the fully connected layers at the end it seems not to play a big role.

This might be highly dependent on the network architecture / dataset.

XPath 1.0, which is what MS implements, does not have the idea of a default namespace. So try this:

XDocument xdoc = XDocument.Load(@"C:\SampleXML.xml");
XmlNamespaceManager xnm = new XmlNamespaceManager(new NameTable()); 
xnm.AddNamespace("x", "http://demo.com/2011/demo-schema");
Console.WriteLine(xdoc.XPathSelectElement("/x:Report/x:ReportInfo/x:Name", xnm) == null);

Use OUTER APPLY instead of LEFT JOIN:

SELECT u.id, mbg.marker_value 
FROM dps_user u
OUTER APPLY 
    (SELECT TOP 1 m.marker_value, um.profile_id
     FROM dps_usr_markers um (NOLOCK)
         INNER JOIN dps_markers m (NOLOCK) 
             ON m.marker_id= um.marker_id AND 
                m.marker_key = 'moneyBackGuaranteeLength'
     WHERE um.profile_id=u.id 
     ORDER BY m.creation_date
    ) AS MBG
WHERE u.id = 'u162231993';

Unlike JOIN, APPLY allows you to reference the u.id inside the inner query.

If you prefer a one-liner:

matched_lines = [line for line in my_string.split('\n') if "substring" in line]
