To reduce cyclomatic complexity use a map:

Map<String,Callable<Object>> map = new HashMap < > ( ) ;
map . put ( "apple" , new Callable<Object> () { public Object call ( method1 ( ) ; return null ; } ) ;
...
map . get ( x ) . call ( ) ;

If you want to delete lines 5 through 10 and 12:

sed -e '5,10d;12d' file

This will print the results to the screen. If you want to save the results to the same file:

sed -i.bak -e '5,10d;12d' file

This will back the file up to file.bak, and delete the given lines.

Note: Line numbers start at 1. The first line of the file is 1, not 0.

TinyXML, and also Boost.PropertyTree. The latter does not fulfill all official requirements, but is very simple.

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.feature_wrapper span {
    float: left;
    clear: left;
    display:inline
}

EDIT: now browsers have better support you can make use of the do inline-block.

.feature_wrapper span {
    display:inline-block;
    *display:inline; *zoom:1;
}

Depending on the text-align this will appear as through its inline while also acting like a block element.

You should be able to use the /quiet or /qn options with msiexec to perform a silent install.

MSI packages export public properties, which you can set with the PROPERTY=value syntax on the end of the msiexec parameters.

For example, this command installs a package with no UI and no reboot, with a log and two properties:

msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2

You can read the options for msiexec by just running it with no options from Start -> Run.

package pack2;

import java.util.Scanner;

public class group {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    int temp=0,i=0,j=0;
    System.out.println("Enter 5 element of array");
    for(i=0;i<5;i++)
    value[i]=data.nextInt();
     for(i=0;i<5;i++)
     {
     for(j=i;j<5;j++)
     {
      if(value[i]>value[j])
      {
       temp=value[i];
       value[i]=value[j];
       value[j]=temp;
      }
     }

     }
      System.out.println("Increasing Order:");
      for(i=0;i<5;i++)
           System.out.println(""+value[i]); 
    }

      $filename= time()."pdf";

Not sure if I fully understood your problem, but if it's just about creating export scripts, you should forward engineer to SQL script - Ctrl + Shift + G or File -> Export -> first option.

I had trouble using the answers above. The date ranges were missing single days due to timezone shift caused by the local day light saving time (DST). I implemented a version using UTC dates that fixes that problem:

function dateRange(startDate, endDate, steps = 1) {
  const dateArray = [];
  let currentDate = new Date(startDate);

  while (currentDate <= new Date(endDate)) {
    dateArray.push(new Date(currentDate));
    // Use UTC date to prevent problems with time zones and DST
    currentDate.setUTCDate(currentDate.getUTCDate() + steps);
  }

  return dateArray;
}

const dates = dateRange('2020-09-27', '2020-10-28');
console.log(dates);

Note: Whether a certain timezone or DST is applied, depends entirely on your locale. Overriding this is generally not a good idea. Using UTC dates mitigates most of the time related problems.

Bonus: You can set the time interval for which you want to create timestamps with the optional steps parameter. If you want weekly timetamps set steps to 7.

Bootstrap 4

Documentation says (here):

Rows are wrappers for columns. Each column has horizontal padding (called a gutter) for controlling the space between them. This padding is then counteracted on the rows with negative margins. This way, all the content in your columns is visually aligned down the left side.

So the right answer is: set cols' padding-left/right equal to minus your row's margin-left/right. That simple.

#my-row {
  margin-left: -80px;
  margin-right: -80px;
}

#my-col {
  padding-left: 80px;
  padding-right: 80px;
}

If you're trying to use this on Cygwin, then you need to follow the instructions in this answer. (It's a problem how Cygwin treats Windows symlinks.)

Just use:

 param.AddWithValue("@Date_Of_Birth",DOB);

That will take care of all your problems.

You need to access a geocoding service (i.e. from Google), there is no simple formula to transfer addresses to geo coordinates.

For fields where NULL is acceptable, you could use var_export($var, true) to output the string, integer, or NULL literal. Note that you would not surround the output with quotes because they will be automatically added or omitted.

For example:

mysql_query("insert into table2 (f1, f2) values ('{$row['string_field']}', ".var_export($row['null_field'], true).")");

DateTime values should be inserted as if they are strings surrounded by single quotes:

'20100301'

SQL Server allows for many accepted date formats and it should be the case that most development libraries provide a series of classes or functions to insert datetime values properly. However, if you are doing it manually, it is important to distinguish the date format using DateFormat and to use generalized format:

Set DateFormat MDY --indicates the general format is Month Day Year

Insert Table( DateTImeCol )
Values( '2011-03-12' )

By setting the dateformat, SQL Server now assumes that my format is YYYY-MM-DD instead of YYYY-DD-MM.

SET DATEFORMAT

SQL Server also recognizes a generic format that is always interpreted the same way: YYYYMMDD e.g. 20110312.

If you are asking how to insert the current date and time using T-SQL, then I would recommend using the keyword CURRENT_TIMESTAMP. For example:

Insert Table( DateTimeCol )
Values( CURRENT_TIMESTAMP )

I know this was answered already, but I just ran into the same issue trying to specify the schema to use for the liquibase command line.

Update As of JDBC v9.4 you can specify the url with the new currentSchema parameter like so:

jdbc:postgresql://localhost:5432/mydatabase?currentSchema=myschema

Appears based on an earlier patch:

http://web.archive.org/web/20141025044151/http://postgresql.1045698.n5.nabble.com/Patch-to-allow-setting-schema-search-path-in-the-connectionURL-td2174512.html

Which proposed url's like so:

jdbc:postgresql://localhost:5432/mydatabase?searchpath=myschema

Simple and to the POINT:

jQuery - Upon Clicking a button or div or a label element. Check off all checkboxes on the page. Keep in mind you'll have to adjust :checkbox to make it more specific.

jQuery("#My-Button").click(function() {

  jQuery(':checkbox').each(function() {
    if(this.checked == true) {
      this.checked = false;                        
    } else {
      this.checked = true;                        
    }      
  });

});

With Dulwich tip you should be able to do:

from dulwich.repo import Repo
Repo("/path/to/source").clone("/path/to/target")

This is still very basic - it copies across the objects and the refs, but it doesn't yet create the contents of the working tree if you create a non-bare repository.

In my case, I configured an external Maven installation, and I made sure to be using a JDK instead of a JRE (in the eclipse configuration, and in the Server Environment). You can run a Maven Build of the project from eclipse to check everything is working ok.

After that, I updated the maven projects, cleaned and built the projects, cleaned the server, and redeployed the artifacts.

Parsing is to read the value of one object to convert it to another type. For example you may have a string with a value of "10". Internally that string contains the Unicode characters '1' and '0' not the actual number 10. The method Integer.parseInt takes that string value and returns a real number.

String tenString = "10"

//This won't work since you can't add an integer and a string
Integer result = 20 + tenString;

//This will set result to 30
Integer result = 20 + Integer.parseInt(tenString);

tried all the above, end up doing this

<div style="width:100%; background-color:red; text-align:center;">
        <div style="width:900px; margin:0 auto; background-color:blue;">
            hello
        </div>
    </div>

Based on the accepted response by tiago, here is a small generic function that exports a numpy array to an image having the same resolution as the array:

import matplotlib.pyplot as plt
import numpy as np

def export_figure_matplotlib(arr, f_name, dpi=200, resize_fact=1, plt_show=False):
    """
    Export array as figure in original resolution
    :param arr: array of image to save in original resolution
    :param f_name: name of file where to save figure
    :param resize_fact: resize facter wrt shape of arr, in (0, np.infty)
    :param dpi: dpi of your screen
    :param plt_show: show plot or not
    """
    fig = plt.figure(frameon=False)
    fig.set_size_inches(arr.shape[1]/dpi, arr.shape[0]/dpi)
    ax = plt.Axes(fig, [0., 0., 1., 1.])
    ax.set_axis_off()
    fig.add_axes(ax)
    ax.imshow(arr)
    plt.savefig(f_name, dpi=(dpi * resize_fact))
    if plt_show:
        plt.show()
    else:
        plt.close()

As said in the previous reply by tiago, the screen DPI needs to be found first, which can be done here for instance: http://dpi.lv

I've added an additional argument resize_fact in the function which which you can export the image to 50% (0.5) of the original resolution, for instance.

When writing code you generally don't want to repeat yourself. If you have an class that can be constructed with various numbers of parameters a common solution to avoid repeating yourself is to simply call another constructor with defaults in the missing arguments. There is only one annoying restriction to this - it must be the first line of the declared constructor. Example:

MyClass()
{
   this(default1, default2);
}

MyClass(arg1, arg2)
{
   validate arguments, etc...
   note that your validation logic is only written once now
}

As for the super() constructor, again unlike super.method() access it must be the first line of your constructor. After that it is very much like the this() constructors, DRY (Don't Repeat Yourself), if the class you extend has a constructor that does some of what you want then use it and then continue with constructing your object, example:

YourClass extends MyClass
{
   YourClass(arg1, arg2, arg3)
   {
      super(arg1, arg2) // calls MyClass(arg1, arg2)
      validate and process arg3...
   }
}

Additional information:

Even though you don't see it, the default no argument constructor always calls super() first. Example:

MyClass()
{
}

is equivalent to

MyClass()
{
   super();
}

I see that many have mentioned using the this and super keywords on methods and variables - all good. Just remember that constructors have unique restrictions on their usage, most notable is that they must be the very first instruction of the declared constructor and you can only use one.

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

As of Node.js 14.3.0 the top-level await is supported.

Required flag: --experimental-top-level-await.

For Python 3.x you can convert your text to raw bytes through:

bytes("my data", "encoding")

For example:

bytes("attack at dawn", "utf-8")

The object returned will work with outfile.write.

This is best it will do the Job done. It will re-size your Map. No need to inspect element anymore to re-size your Map. What it does it will automatically trigger re-size event .

        {
            google.maps.event.trigger(map, 'resize');
        });

        map_array[Next].setZoom( map.getZoom() - 1 );
    map_array[Next].setZoom( map.getZoom() + 1 );

$("#element").validate().valid()

After installing and configuring Hadoop, you can quickly run the command netstat -tulpn

to find the ports open. In the new version of Hadoop 3.1.3 the ports are as follows:-

localhost:8042 Hadoop, localhost:9870 HDFS, localhost:8088 YARN

You'll have to use the ChannelFactory class.

Here's an example:

var myBinding = new BasicHttpBinding();
var myEndpoint = new EndpointAddress("http://localhost/myservice");
using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint))
{
    IMyService client = null;

    try
    {
        client = myChannelFactory.CreateChannel();
        client.MyServiceOperation();
        ((ICommunicationObject)client).Close();
        myChannelFactory.Close();
    }
    catch
    {
        (client as ICommunicationObject)?.Abort();
    }
}

As detailed above, the generic List<> is the best way of doing it.

If you're stuck in .NET 1.*, then you will have to use the ArrayList class instead. This does not have compile-time type checking and you also have to add casting - messy.

Successive versions have also implemented various variations - including thread safe variants.

This is how Microsoft explains it:

.NET Framework is the "full" or "traditional" flavor of .NET that's distributed with Windows. Use this when you are building a desktop Windows or UWP app, or working with older ASP.NET 4.6+.

.NET Core is cross-platform .NET that runs on Windows, Mac, and Linux. Use this when you want to build console or web apps that can run on any platform, including inside Docker containers. This does not include UWP/desktop apps currently.

Xamarin is used for building mobile apps that can run on iOS, Android, or Windows Phone devices.

Xamarin usually runs on top of Mono, which is a version of .NET that was built for cross-platform support before Microsoft decided to officially go cross-platform with .NET Core. Like Xamarin, the Unity platform also runs on top of Mono.

A common point of confusion is where ASP.NET Core fits in. ASP.NET Core can run on top of either .NET Framework (Windows) or .NET Core (cross-platform), as detailed in this answer: Difference between ASP.NET Core (.NET Core) and ASP.NET Core (.NET Framework)

<input type="text" value="Your value">

Use the value attribute for the pre filled in values.

I often confuse the two. Better to remember through their output:

> for Overwrite

$ touch someFile.txt
$ echo ">" > someFile.txt
$ cat someFile.txt
  >
$ echo ">" > someFile.txt
$ cat someFile.txt
  >

>> for Append

$ echo ">" > someFile.txt
$ cat someFile.txt
  >
$ echo ">" >> someFile.txt
$ cat someFile.txt
  >>

Actually you have a code compiled targeting a higher JDK (JDK 1.8 in your case) but at runtime you are supplying a lower JRE(JRE 7 or below).

you can fix this problem by adding target parameter while compilation
e.g. if your runtime target is 1.7, you should use 1.7 or below

javac -target 1.7 *.java

if you are using eclipse, you can sent this parameter at Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" = choose your runtime jre version or lower.

Try this:

@echo off 
copy "C:\Remoting.config-Training" "C:\Remoting.config"
start C:\ThirdParty.exe
exit

Since Java 11, there is a new method String.lines:

/**
 * Returns a stream of lines extracted from this string,
 * separated by line terminators.
 * ...
 */
public Stream<String> lines() { ... }

Usage:

"line1\nline2\nlines3"
    .lines()
    .forEach(System.out::println);

Let's assume that You have a List<int> intList = new List<int>{1,2,3} if You want to get a max value You could do

int maxValue = intList.Max();

I had similar issue. In my case on disabled elements was applied that aspNetDisabled class and all disabled controls had wrong colors. So, I used jquery to remove this class on every element/control I wont and everything works and looks great now.

This is my code for removing aspNetDisabled class:

$(document).ready(function () {

    $("span").removeClass("aspNetDisabled");
    $("select").removeClass("aspNetDisabled");
    $("input").removeClass("aspNetDisabled");

});

In the spirit of arrow sexiness, you could create a micro clamp/constrain/gate/&c. function using rest parameters

var clamp = (...v) => v.sort((a,b) => a-b)[1];

Then just pass in three values

clamp(100,-3,someVar);

That is, again, if by sexy, you mean 'short'

E.X You can use Singleton for global information that needs to be injected.

In my case, I was keeping the Logged user detail(username, permissions etc.) in Global Static Class. And when I tried to implement the Unit Test, there was no way I could inject dependency into Controller classes. Thus I have changed my Static Class to Singleton pattern.

public class SysManager
{
    private static readonly SysManager_instance = new SysManager();

    static SysManager() {}

    private SysManager(){}

    public static SysManager Instance
    {
        get {return _instance;}
    }
}

Bitmasks are used when you want to encode multiple layers of information in a single number.

So (assuming unix file permissions) if you want to store 3 levels of access restriction (read, write, execute) you could check for each level by checking the corresponding bit.

rwx
---
110

110 in base 2 translates to 6 in base 10.

So you can easily check if someone is allowed to e.g. read the file by and'ing the permission field with the wanted permission.

Pseudocode:

PERM_READ = 4
PERM_WRITE = 2
PERM_EXEC = 1

user_permissions = 6

if (user_permissions & PERM_READ == TRUE) then
  // this will be reached, as 6 & 4 is true
fi

You need a working understanding of binary representation of numbers and logical operators to understand bit fields.

You'll want to include action="javascript:void(0);" to your form to prevent page reloads and maintain HTML standard.

fwiw, for a conda env:

 conda install -c anaconda pymysql 

I have the same problem. but when i add direction: rtl; in tabs and accordion combo but it crashes my structure.

The way to do it is add div with direction: rtl; as parent element, and for child div set direction: ltr;.

I use this first https://api.jquery.com/wrap/

$( ".your selector of child element" ).wrap( "<div class='scroll'></div>" );

then just simply work with css :)

In children div add to css

 .your_class {
            direction: ltr;    
        }

And to parent div added by jQuery with class .scroll

.scroll {
            unicode-bidi:bidi-override;
            direction: rtl;
            overflow: scroll;
            overflow-x: hidden!important;
        }

With Xcode 9 - Simulator, you can pick & drag any corner of simulator to resize it and set according to your requirement.

Look at this snapshot.

Note: With Xcode 9.1+, Simulator scale options are changed.

Keyboard short-keys:
According to Xcode 9.1+

Physical Size       ? 1      command + 1
Pixel Accurate      ? 2      command + 2

According to Xcode 9

50% Scale           ? 1      command + 1
100% Scale          ? 2      command + 2
200% Scale          ? 3      command + 3

Simulator scale options from Xcode Menu:

Xcode 9.1+:
Menubar ? Window ? "Here, options available change simulator scale" (Physical Size & Pixel Accurate)

Pixel Accurate: Resizes your simulator to actual (Physical) device's pixels, if your mac system display screen size (pixel) supports that much high resolution, else this option will remain disabled.

Tip: rotate simulator ( ? + ? or ? + ? ), if Pixel Accurate is disabled. It may be enabled (if it fits to screen) in landscape.

Xcode 9.0
Menubar ? Window ? Scale ? "Here, options available change simulator scale"

Tip: How do you get screen shot with 100% (a scale with actual device size) that can be uploaded on AppStore?

Disable 'Optimize Rendering for Window scale' from Debug menu, before you take a screen shot (See here: How to take screenshots in the iOS simulator)

There is an option

To get right-click to paste to work:

• Right-click on the title bar > Properties

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

First of all, public static non-final fields are evil. Spring does not allow injecting to such fields for a reason.

Your workaround is valid, you don't even need getter/setter, private field is enough. On the other hand try this:

@Value("${my.name}")
public void setPrivateName(String privateName) {
    Sample.name = privateName;
}  

(works with @Autowired/@Resource). But to give you some constructive advice: Create a second class with private field and getter instead of public static field.

Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color is the fastest to respond (subjective).

Add the following to your body and your links will have a tap effect.

body {
    -webkit-tap-highlight-color: #ccc;
}

If you're running an Apache server on your localhost (don't do this on a production server), you can also post the results to a script instead of writing it to console.

So instead of console.log, you can write:

JSONP('http://localhost/save.php', {fn: 'filename.txt', data: json});

Then save.php can do this

<?php

 $fn = $_REQUEST['fn'];
 $data = $_REQUEST['data'];

 file_put_contents("path/$fn", $data);

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).

It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)

As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.

In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.

jQuery.load() is probably the easiest way to load data asynchronously using a selector, but you can also use any of the jquery ajax methods (get, post, getJSON, ajax, etc.)

Note that load allows you to use a selector to specify what piece of the loaded script you want to load, as in

$("#mydiv").load(location.href + " #mydiv");

Note that this technically does load the whole page and jquery removes everything but what you have selected, but that's all done internally.

Short answer: 60-80%

Long answer: I think it totally depends on the nature of your project. I typically start a project by unit testing every practical piece. By the first "release" of the project you should have a pretty good base percentage based on the type of programming you are doing. At that point you can start "enforcing" a minimum code coverage.

Here's what u can also try....

run your application....while it is still running launch your command prompt

while your application is running type netstat -n on the command prompt. You should see a list of TCP/IP connections. Check if your list is not very long. Ideally you should have less than 5 connections in the list. Check the status of the connections.
If you have too many connections with a TIME_WAIT status it means the connection has been closed and is waiting for the OS to release the resources. If you are running on Windows, the default ephemeral port rang is between 1024 and 5000 and the default time it takes Windows to release the resource from TIME_WAIT status is 4 minutes. So if your application used more then 3976 connections in less then 4 minutes, you will get the exception you got.

Suggestions to fix it:

1. Add a connection pool to your connection string.

If you continue to receive the same error message (which is highly unlikely) you can then try the following: (Please don't do it if you are not familiar with the Windows registry)

1. Run regedit from your run command. In the registry editor look for this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters:

Modify the settings so they read:

MaxUserPort = dword:00004e20 (10,000 decimal) TcpTimedWaitDelay = dword:0000001e (30 decimal)

This will increase the number of ports to 10,000 and reduce the time to release freed tcp/ip connections.

Only use suggestion 2 if 1 fails.

Thank you.

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

If you are running cmake to generate SomeLib yourself (say as part of a superbuild), consider using the User Package Registry. This requires no hard-coded paths and is cross-platform. On Windows (including mingw64) it works via the registry. If you examine how the list of installation prefixes is constructed by the CONFIG mode of the find_packages() command, you'll see that the User Package Registry is one of elements.

Brief how-to

Associate the targets of SomeLib that you need outside of that external project by adding them to an export set in the CMakeLists.txt files where they are created:

add_library(thingInSomeLib ...)
install(TARGETS thingInSomeLib Export SomeLib-export DESTINATION lib)

Create a XXXConfig.cmake file for SomeLib in its ${CMAKE_CURRENT_BUILD_DIR} and store this location in the User Package Registry by adding two calls to export() to the CMakeLists.txt associated with SomeLib:

export(EXPORT SomeLib-export NAMESPACE SomeLib:: FILE SomeLibConfig.cmake) # Create SomeLibConfig.cmake
export(PACKAGE SomeLib)                                                    # Store location of SomeLibConfig.cmake

Issue your find_package(SomeLib REQUIRED) commmand in the CMakeLists.txt file of the project that depends on SomeLib without the "non-cross-platform hard coded paths" tinkering with the CMAKE_MODULE_PATH.

When it might be the right approach

This approach is probably best suited for situations where you'll never use your software downstream of the build directory (e.g., you're cross-compiling and never install anything on your machine, or you're building the software just to run tests in the build directory), since it creates a link to a .cmake file in your "build" output, which may be temporary.

But if you're never actually installing SomeLib in your workflow, calling EXPORT(PACKAGE <name>) allows you to avoid the hard-coded path. And, of course, if you are installing SomeLib, you probably know your platform, CMAKE_MODULE_PATH, etc, so @user2288008's excellent answer will have you covered.

You may need to change the permissions as an administrator. Open up terminal on your Mac and then open the directory that markers.xml is located in. Then type:

sudo chmod 777 markers.xml

You may be prompted for a password. Also, it could be the directories that don't allow full access. I'm not familiar with WordPress, so you may have to change the permission of each directory moving upward to the mysite directory.

jQuery UI has a :data() selector which can also be used. It has been around since Version 1.7.0 it seems.

You can use it like this:

Get all elements with a data-company attribute

var companyElements = $("ul:data(group) li:data(company)");

Get all elements where data-company equals Microsoft

var microsoft = $("ul:data(group) li:data(company)")
                    .filter(function () {
                        return $(this).data("company") == "Microsoft";
                    });

Get all elements where data-company does not equal Microsoft

var notMicrosoft = $("ul:data(group) li:data(company)")
                       .filter(function () {
                           return $(this).data("company") != "Microsoft";
                       });

etc...

One caveat of the new :data() selector is that you must set the data value by code for it to be selected. This means that for the above to work, defining the data in HTML is not enough. You must first do this:

$("li").first().data("company", "Microsoft");

This is fine for single page applications where you are likely to use $(...).data("datakey", "value") in this or similar ways.

What worked for me was to create a viewmodel that contained the date property as a string. Assigning the DateTime property from the domain model and calling the .ToString() on the date property while assigning the value to the viewmodel.

A JSON result from an MVC action method will return the date in a format compatible with the view.

View Model

public class TransactionsViewModel
{
    public string DateInitiated { get; set; }
    public string DateCompleted { get; set; }
}

Domain Model

public class Transaction{
   public DateTime? DateInitiated {get; set;}
   public DateTime? DateCompleted {get; set;}
}

Controller Action Method

public JsonResult GetTransactions(){

var transactions = _transactionsRepository.All;
        var model = new List<TransactionsViewModel>();

        foreach (var transaction in transactions)
        {
            var item = new TransactionsViewModel
            {
                ...............
                DateInitiated = transaction.DateInitiated.ToString(),
                DateCompleted = transaction.DateCompleted.ToString(),
            };

            model.Add(item);
        }
        return Json(model, JsonRequestBehavior.AllowGet);
}

Try this:

if (getResult.Equals(new KeyValuePair<T,U>()))

or this:

if (getResult.Equals(default(KeyValuePair<T,U>)))

~/.bashrc is already a path to .bashrc.

If you do echo ~ you'll see that it's a path to your home directory.

Homebrew directory is /usr/local/bin. Homebrew is installed inside it and everything installed by homebrew will be installed there.

For example, if you do brew install python Homebrew will put Python binary in /usr/local/bin.

Finally, to add Homebrew directory to your path you can run echo "export PATH=/usr/local/lib:$PATH" >> ~/.bashrc. It will create .bashrc file if it doesn't exist and then append the needed line to the end.

You can check the result by running tail ~/.bashrc.

You can persist values using HTML5 storage, Flash Storage, or Gears. The dojo storage library provides a nice wrapper for this.

The file will be stored in a temporary location, so use tmp_name instead of name:

if (move_uploaded_file($_FILES['image']['tmp_name'], __DIR__.'/../../uploads/'. $_FILES["image"]['name'])) {
    echo "Uploaded";
} else {
   echo "File not uploaded";
}

A way better solution is to just use the excelent compatibility script from Anthony Ferrara:

https://github.com/ircmaxell/password_compat

Please, and also, when checking the password, always add a way (preferibly async, so it doesn't impact the check process for timming attacks) to update the hash if needed.

Moving a project from GitHub to GitLab including issues, pull requests Wiki, Milestones, Labels, Release notes and comments

There is a thorough instruction on GitLab Docs:

https://docs.gitlab.com/ee/user/project/import/github.html

tl;dr

• Ensure that any GitHub users who you want to map to GitLab users have either:

  • A GitLab account that has logged in using the GitHub icon - or -
  • A GitLab account with an email address that matches the public email address of the GitHub user

• From the top navigation bar, click + and select New project.

• Select the Import project tab and then select GitHub.
• Select the first button to List your GitHub repositories. You are redirected to a page on github.com to authorize the GitLab application.
• Click Authorize gitlabhq. You are redirected back to GitLab's Import page and all of your GitHub repositories are listed.
• Continue on to selecting which repositories to import.

But Please read the GitLab Docs page for details and hooks!

(it's not much)

you can use index to access list elements

List<string> list1 = new List<string>();
list1[0] //for getting the first element of the list

You are probably missing the viewport meta tag in the html head:

 <meta name="viewport" content="width=device-width, initial-scale=1">

Without it the device assumes and sets the viewport to full size.

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

You use ROWNUM.

ie.

SELECT user FROM Dual WHERE ROWNUM = 1

http://docs.oracle.com/cd/B19306_01/server.102/b14200/pseudocolumns009.htm

I'll offer an oddball alternative. Sometimes it's easier to use different encoding, especially if you're dealing with a variety of systems that don't all handle the details of URL encoding the same way. This isn't the most mainstream approach but can come in handy in certain situations.

Rather than URL-encoding the data, you can base64-encode it. The benefit of this is the encoded data is very generic, consisting only of alpha characters and sometimes trailing ='s. Example:

JSON array-of-strings:

["option", "Fred's dog", "Bill & Trudy", "param=3"]

That data, URL-encoded as the data param:

"data=%5B%27option%27%2C+%22Fred%27s+dog%22%2C+%27Bill+%26+Trudy%27%2C+%27param%3D3%27%5D"

Same, base64-encoded:

"data=WyJvcHRpb24iLCAiRnJlZCdzIGRvZyIsICJCaWxsICYgVHJ1ZHkiLCAicGFyYW09MyJd"

The base64 approach can be a bit shorter, but more importantly it's simpler. I often have problems moving URL-encoded data between cURL, web browsers and other clients, usually due to quotes, embedded % signs and so on. Base64 is very neutral because it doesn't use special characters.

Perhaps this is specific to .net core, I found DisplayName would not work but Display(Name=...) does. This may save someone else the troubleshooting involved :)

//using statements

If you are using the free software R, you can open the matlab files in Rstudio. Very easy!

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

Thanks Ravi and other users .... Nevertheless I have got the solution

SELECT @phoneNumber=
CASE 
  WHEN  ISNULL(rdg2.nPhoneNumber  ,'0') in ('0','-',NULL)
THEN ISNULL(rdg2.nMobileNumber, '0') 
  WHEN ISNULL(rdg2.nMobileNumber, '0')  in ('0','-',NULL)
THEN '0'
  ELSE ISNULL(rdg2.nPhoneNumber  ,'0')
END 
FROM tblReservation_Details_Guest  rdg2 
WHERE nReservationID=@nReservationID

Just need to put '0' instead of 0

Working with Eclipse can be difficult at times, probably when debugging and designing layouts Eclipse sometimes get stuck and we have to restart Eclipse from time to time. Also you get problems with emulators.

Android studio was released very recently and this IDE is not yet heavily used by developers. Therefore, it may contain certain bugs.

This describes the difference between android android studio and eclipse project structure: Android Studio Project Structure (v.s. Eclipse Project Structure)

This teaches you how to use the android studio: http://www.infinum.co/the-capsized-eight/articles/android-studio-vs-eclipse-1-0

Object does not have forEach, it belongs to Array prototype. If you want to iterate through each key-value pair in the object and take the values. You can do this:

Object.keys(a).forEach(function (key){
    console.log(a[key]);
});

Usage note: For an object v = {"cat":"large", "dog": "small", "bird": "tiny"};, Object.keys(v) gives you an array of the keys so you get ["cat","dog","bird"]

This is another way to specify the range of the bit-vector.

x +: N, The start position of the vector is given by x and you count up from x by N.

There is also

x -: N, in this case the start position is x and you count down from x by N.

N is a constant and x is an expression that can contain iterators.

It has a couple of benefits -

1. It makes the code more readable.

2. You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.

First of all, %d is for a int

So %1.16lld makes no sense, because %d is an integer

That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.

What you want to use is the type double, for calculating pi and then using %f or %1.16f.

var d = new Date();
var n = d.getFullYear();

Yes, n will give you the 4 digit year, but you can always use substring or something similar to split up the year, thus giving you only two digits:

var final = n.toString().substring(2);

This will give you the last two digits of the year (2013 will become 13, etc...)

If there's a better way, hopefully someone posts it! This is the only way I can think of. Let us know if it works!

Using map (halfdanrump's answer) is best for me, though haven't timed it...

But if you go for a dictionary, and if you have a big_dict:

1. Make absolutely certain you loop through the the req. This is crucial, and affects the running time of the algorithm (big O, theta, you name it)
2. Write it generic enough to avoid errors if keys are not there.

so e.g.:

big_dict = {'a':1,'b':2,'c':3,................................................}
req = ['a','c','w']

{k:big_dict.get(k,None) for k in req )
# or 
{k:big_dict[k] for k in req if k in big_dict)

Note that in the converse case, that the req is big, but my_dict is small, you should loop through my_dict instead.

In general, we are doing an intersection and the complexity of the problem is O(min(len(dict)),min(len(req))). Python's own implementation of intersection considers the size of the two sets, so it seems optimal. Also, being in c and part of the core library, is probably faster than most not optimized python statements. Therefore, a solution that I would consider is:

dict = {'a':1,'b':2,'c':3,................................................}
req = ['a','c','w',...................]

{k:dic[k] for k in set(req).intersection(dict.keys())}

It moves the critical operation inside python's c code and will work for all cases.

Just ran into this problem. I don't know if it's the same thing that hit your code, but for me the root cause was because I forgot to put name= on the last argument of the url (or path in Django 2.0+) function call.

For instance, the following functions throw the error from the question:

url(r'^foo/(?P<bar>[A-Za-z]+)/$', views.FooBar.as_view(), 'foo')
path('foo/{slug:bar}/', views.FooBar, 'foo')

But these actually work:

url(r'^foo/(?P<bar>[A-Za-z]+)/$', views.FooBar.as_view(), name='foo')
path('foo/{slug:bar}/', views.FooBar, name='foo')

The reason why the traceback is unhelpful is because internally, Django wants to parse the given positional argument as the keyword argument kwargs, and since a string is an iterable, an atypical code path begins to unfold. Always use name= on your urls!

Swift Method, and supply a demo.

func topMostController() -> UIViewController {
    var topController: UIViewController = UIApplication.sharedApplication().keyWindow!.rootViewController!
    while (topController.presentedViewController != nil) {
        topController = topController.presentedViewController!
    }
    return topController
}

func demo() {
    let vc = ViewController()
    let nav = UINavigationController.init(rootViewController: vc)
    topMostController().present(nav, animated: true, completion: nil)
}

Both commands are correct

php_value post_max_size 30M 

php_value upload_max_filesize 30M 

BUT to use the .htaccess you have to enable rewrite_module in Apache config file. In httpd.conf find this line:

# LoadModule rewrite_module modules/mod_rewrite.so

and remove the #.

What Identity is your Application Pool for the Web application running as, to troubleshoot, try creating a new App Pool with say Network Service as its identity and make your web application use that new App Pool you created and see if the error persists.

If you want to set the timeout to 20 minutes, use something like this:

    <configuration>
      <system.web>
         <sessionState timeout="20"></sessionState>
      </system.web>
    </configuration>

Here's another way to do this:

- name: my command
  command: echo stuff

group_names is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :

group_names is a list (array) of all the groups the current host is in.

I'm having the same problem to solve, because I need to install JDK8 to run Android SDK Manager (because it seems that don't work well with JDK9). However, I tell you how I solve all problems on a Mac (Sierra).

First, you need brew with cask and jenv.

1. You can find an useful guide here,Homebrew Cask Installation Guide. Remember to tap 'caskroom/versions' running in the terminal: brew tap caskroom/versions
2. After that, install jenv with: brew install jenv
3. Install whatever version you want with cask brew cask install java8 (or java7 or java if you want to install the latest version, jdk9)
4. The last step is to configure which version to run (and let jenv to manage your JAVA_HOME) jenv versions to list all versions installed on your machine and then activate the one you want with jenv global [JDK_NAME_OF_LIST]

You could find other useful informations here on this Github Gist brew-java-and-jenv.md, on this blog Install multiple JDK on a Mac and on Jenv Website

Try adding a semi colon to the end of your structure:

 struct sotrudnik {
    string name;

    string razread;
    int zarplata;
} //Semi colon here

One liner in ES6 just because it's clean.

const isEven = (num) => num % 2 == 0;

Write this in each "new activity" after you initialized your new intent->

Unlike div, p ¹ which are Block Level elements which can take up margin on all sides,span² cannot as it's an Inline element which takes up margins horizontally only.

From the specification:

Margin properties specify the width of the margin area of a box. The 'margin' shorthand property sets the margin for all four sides while the other margin properties only set their respective side. These properties apply to all elements, but vertical margins will not have any effect on non-replaced inline elements.

Demo 1 (Vertical margin not applied as span is an inline element)

Solution? Make your span element, display: inline-block; or display: block;.

Demo 2

Would suggest you to use display: inline-block; as it will be inline as well as block. Making it block only will result in your element to render on another line, as block level elements take 100% of horizontal space on the page, unless they are made inline-block or they are floated to left or right.

^{2. Inline Elements - MDN Resource}

In SQL Server, functions and stored procedure are two different types of entities.

Function: In SQL Server database, the functions are used to perform some actions and the action returns a result immediately. Functions are two types:

1. System defined

2. User defined

Stored Procedures: In SQL Server, the stored procedures are stored in server and it can be return zero, single and multiple values. Stored Procedures are two types:

1. System Stored Procedures
2. User Defined Procedures

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

When you extend FragmentActivity or Activity and not ListActivity, you'll want to take a look at:

ListView.setEmptyView()

I would suggest you to either use <table> or CSS.

CSS is preferred for being more flexible. An example would be:

<!-- of course, you should move the inline CSS style to your stylesheet -->
<!-- main container, width = 70% of page, centered -->
<div id="contentBox" style="margin:0px auto; width:70%">

 <!-- columns divs, float left, no margin so there is no space between column, width=1/3 -->
    <div id="column1" style="float:left; margin:0; width:33%;">
     CONTENT
    </div>

    <div id="column2" style="float:left; margin:0;width:33%;">
     CONTENT
    </div>

    <div id="column3" style="float:left; margin:0;width:33%">
     CONTENT
    </div>
</div>

jsFiddle: http://jsfiddle.net/ndhqM/

Using float:left would make 3 columns stick to each other, coming in from left inside the centered div "content box".

This is my LDAP Java login test application supporting LDAP:// and LDAPS:// self-signed test certificate. Code is taken from few SO posts, simplified implementation and removed legacy sun.java.* imports.

• how to accept self-signed certificates for JNDI/LDAP connections?
• Authenticating against Active Directory with Java on Linux

Usage
I have run this in Windows7 and Linux machines against WinAD directory service. Application prints username and member groups.

$ java -cp classes test.LoginLDAP url=ldap://1.2.3.4:389 [email protected] password=mypwd

$ java -cp classes test.LoginLDAP url=ldaps://1.2.3.4:636 [email protected] password=mypwd

Test application supports temporary self-signed test certificates for ldaps:// protocol, this DummySSLFactory accepts any server cert so man-in-the-middle is possible. Real life installation should import server certificate to a local JKS keystore file and not using dummy factory.

Application uses enduser's username+password for initial context and ldap queries, it works for WinAD but don't know if can be used for all ldap server implementations. You could create context with internal username+pwd then run queries to see if given enduser is found.

So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.

tail -n 20 /var/log/apache2/error.log

I used StoredProcedureEFCore nuget package by https://github.com/verdie-g/StoredProcedureEFCore,EnterpriseLibrary.Data.NetCore,EFCor.SqlServer,EFCore.Tools

I tried DbFirst approach with {Repository pattern}.. i think so

startup.cs

ConfigureServices(IServiceCollection services){
    services.AddDbContext<AppDbContext>(opt => opt
                   .UseSqlServer(Configuration.GetConnectionString("SampleConnectionString")));
    services.AddScoped<ISomeDAL, SomeDAL>();

}
            
    public  class AppDbContext : DbContext{
public AppDbContext(DbContextOptions<AppDbContext> options) : base(options)
    {}
}

ISomeDAl Interface has {GetPropertiesResponse GetAllPropertiesByCity(int CityId);}

public class SomeDAL : ISomeDAL
{
     private readonly AppDbContext context;

     public SomeDAL(AppDbContext context)
         {
             this.context = context;
         }
     public  GetPropertiesResponse GetAllPropertiesByCity(int CityId)
     {
         //Create Required Objects for response 
         //wont support ref Objects through params
         context.LoadStoredProc(SQL_STATEMENT)

                       ORMapping<GenericRespStatus> orm = new  ORMapping<GenericRespStatus>();
                       orm.AssignObject(r, _Status);
                  }

                  if (r.NextResult())
                  {

                       while (r.Read())
                       {
                           Property = new Property();
                           ORMapping<Property> orm = new ORMapping<Property>();
                           orm.AssignObject(r, Property);
                           _propertyDetailsResult.Add(Property);
                       }
                  }    
           });
    return new GetPropertiesResponse{Status=_Status,PropertyDetails=_propertyDetailsResult}; 
    }
}

public class GetPropertiesResponse
{
     public GenericRespStatus Status;
     public List<Property> PropertyDetails;
     public GetPropertiesResponse()
         {
             PropertyDetails = new List<Property>();
         }
}
public class GenericRespStatus

    {
        PropertyInfo[] propertyInfos = typeof(T).GetProperties();
        for (int i = 0; i < record.FieldCount; i++)
        {
            if (propertyInfos.Any(obj => obj.Name == record.GetName(i))) //&& record.GetValue(i) != DBNull.Value
            {
                propertyInfos.Single(obj => obj.Name == record.GetName(i)).SetValue(myClass, Convert.ChangeType(record.GetValue(i), record.GetFieldType(i)));
            }
        }
    }
}

use wget module of python instead. Here is a snippet

import wget
wget.download(url)

I had same issue. What I did, removed anaconda directory from the install location and re-install after that it worked as I anticipated

Change as per below

@font-face {
    font-family: "Futura";
    src: url("../fonts/Futura_Medium_BT.eot"); /* IE */
    src: local("Futura"), url( "../fonts/Futura_Medium_BT.ttf" ) format("truetype"); /* non-IE */  
}

body nav {
     font-family: "Futura";
    font-size:1.2em;
    height: 40px;
}

Both styles, with a touch of tweaking, would work.

The first method uses a Javascript Constructor, which like most things has pros and cons.

 // By convention, constructors start with an upper case letter
function MakePerson(name,age) {
  // The magic variable 'this' is set by the Javascript engine and points to a newly created object that is ours.
  this.name = name;
  this.age = age;
  this.occupation = "Hobo";
}
var jeremy = new MakePerson("Jeremy", 800);

On the other hand, your other method is called the 'Revealing Closure Pattern' if I recall correctly.

function makePerson(name2, age2) {
  var name = name2;
  var age = age2;

  return {
    name: name,
    age: age
  };
}

Example:
How to transfer putty configuration and session configuration from one user account to another e.g. when created a new account and want to use the putty sessions/configurations from the old account

Process:
- Export registry key from old account into a file
- Import registry key from file into new account

Export reg key: (from OLD account)

1. Login into the OLD account e.g. tomold
2. Open normal 'command prompt' (NOT admin !)
3. Type 'regedit'
4. Navigate to registry section where the configuration is being stored e.g. [HKEY_CURRENT_USER\SOFTWARE\SimonTatham] and click on it
5. Select 'Export' from the file menu or right mouse click (radio ctrl 'selected branch')
6. Save into file and name it e.g. 'puttyconfig.reg'
7. Logout again

Import reg key: (into NEW account)

8. Login into NEW account e.g. tom

9. Open normal 'command prompt' (NOT admin !)

10. Type 'regedit'

11. Select 'Import' from the menu

12. Select the registry file to import e.g. 'puttyconfig.reg'

13. Done

Note:
Do not use an 'admin command prompt' as settings are located under '[HKEY_CURRENT_USER...] 'and regedit would run as admin and show that section for the admin-user rather then for the user to transfer from and/or to.

Use the constructor: new List<object>(myArray)

You can solve this problem by following two ways:
A) Start your WAMP befor you login to skype. So that WAMP will take over the the port and there will be no conflict with the port number. And you are able to use Skype as well as WAMP.
But this is not the permanent solution for your problem. Whenever you want to start WAMP you need to signout Skype first and than only you are able to start WAMP. Which is really i don’t like.

B) Second option is to change the port of Skype itself, so that it will not conflict with WAMP. Following screen/steps will help you to solve this problem:
1) SignIn to Skype.
2) Got to the Tools -> options
3) Select the “Advanced” -> Connection
4) Unchecked “Use port 80 and 443 as alternatives for incoming connections” checkbox and click save.
5) Now Signout and SignIn again to skype. (this change will take affect only you relogin to skype)
Now every time you start WAMP will not conflict with skype.

Use this to get the page scroll position.

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

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

I know its already answered, still i am just trying to make it simple. So angular.copy(data) you can use in case where you want to modify/change your received object by keeping its original values unmodified/unchanged.

For example: suppose i have made api call and got my originalObj, now i want to change the values of api originalObj for some case but i want the original values too so what i can do is, i can make a copy of my api originalObj in duplicateObj and modify duplicateObj this way my originalObj values will not change. In simple words duplicateObj modification will not reflect in originalObj unlike how js obj behave.

 $scope.originalObj={
            fname:'sudarshan',
            country:'India'
        }
        $scope.duplicateObj=angular.copy($scope.originalObj);
        console.log('----------originalObj--------------');
        console.log($scope.originalObj);
        console.log('-----------duplicateObj---------------');
        console.log($scope.duplicateObj);

        $scope.duplicateObj.fname='SUD';
        $scope.duplicateObj.country='USA';
        console.log('---------After update-------')
        console.log('----------originalObj--------------');
        console.log($scope.originalObj);
        console.log('-----------duplicateObj---------------');
        console.log($scope.duplicateObj);

Result is like....

    ----------originalObj--------------
manageProfileController.js:1183 {fname: "sudarshan", country: "India"}
manageProfileController.js:1184 -----------duplicateObj---------------
manageProfileController.js:1185 {fname: "sudarshan", country: "India"}
manageProfileController.js:1189 ---------After update-------
manageProfileController.js:1190 ----------originalObj--------------
manageProfileController.js:1191 {fname: "sudarshan", country: "India"}
manageProfileController.js:1192 -----------duplicateObj---------------
manageProfileController.js:1193 {fname: "SUD", country: "USA"}

Change It like this, It worked for me. Hope It helps. firs I did

$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'changed';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

Then I Changed Like this...

$cfg['Servers'][$i]['verbose'] = 'mysql wampserver';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'root';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

There might be just a typo anywhere inside a file imported by the config. For example, I made a typo deep inside my config file:

loccation /sense/movies/ {
                  mp4;
        }

(loccation instead of location), and this causes the error:

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/sites-enabled/xxx.xx:1

sp_change_users_login is deprecated.

Much easier is:

ALTER USER usr1 WITH LOGIN = login1;

Try this.

SELECT 
  CASE 
     WHEN FRUIT = 'A' THEN 'APPLE'
     WHEN FRUIT = 'B' THEN 'BANANA'
     ELSE 'UNKNOWN FRUIT'
  END AS FRUIT
FROM FRUIT_TABLE;

Just use a logging library, like log4net, and have it log to a file appender.

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

Use this css, as you already have the markup for it:

.img-container {
    position: absolute;
    top: 50%;
    left: 50%;
}

.img-container > img {
  margin-top:-50%;
  margin-left:-50%;  
}

Here is a working JsBin: http://jsbin.com/ihilUnI/1/edit

This solution only works for square images (because a percentage margin-top value depends on the width of the container, not the height). For random-size images, you can do the following:

.img-container {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%); /* add browser-prefixes */
}

Working JsBin solution: http://jsbin.com/ihilUnI/2/edit

This works for me:

import Cookies from 'universal-cookie';
const cookies = new Cookies();

function headers(set_cookie=false) {
  let headers = {
    'Accept':       'application/json',
    'Content-Type': 'application/json',
    'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
};
if (set_cookie) {
    headers['Authorization'] = "Bearer " + cookies.get('remember_user_token');
}
return headers;
}

Then build your call:

export function fetchTests(user_id) {
  return function (dispatch) {
   let data = {
    method:      'POST',
    credentials: 'same-origin',
    mode:        'same-origin',
    body:        JSON.stringify({
                     user_id: user_id
                }),
    headers:     headers(true)
   };
   return fetch('/api/v1/tests/listing/', data)
      .then(response => response.json())
      .then(json => dispatch(receiveTests(json)));
    };
  }

sudo apt-get install mysql-client-core-5.5

You need to make TestGetMethod async too and attach await in front of GetIdList(); will unwrap the task to List<int>, So if your helper function is returning Task make sure you have await as you are calling the function async too.

public Task<List<int>> TestGetMethod()
{
    return GetIdList();
}    

async Task<List<int>> GetIdList()
{
    using (HttpClient proxy = new HttpClient())
    {
        string response = await proxy.GetStringAsync("www.test.com");
        List<int> idList = JsonConvert.DeserializeObject<List<int>>();
        return idList;
    }
}

Another option

public async void TestGetMethod(List<int> results)
{
    results = await GetIdList(); // await will unwrap the List<int>
}

This doesn't have anything to do with app.js at all. Instead, this warning is logged when you include the Angular JS library more than once.

I've managed to reproduce the error in this JSBin. Note the two script tags (two different versions):

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.14/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>

Relevant Angular code at GitHub.

DateTimeFormatter has in-built formats that can directly be used to parse a character sequence. It is case Sensitive, Nov will work however nov and NOV wont work:

DateTimeFormatter pattern = DateTimeFormatter.ofPattern("yyyy-MMM-dd");

try {
    LocalDate datetime = LocalDate.parse(oldDate, pattern);
    System.out.println(datetime); 
} catch (DateTimeParseException e) {
    // DateTimeParseException - Text '2019-nov-12' could not be parsed at index 5
    // Exception handling message/mechanism/logging as per company standard
}

DateTimeFormatterBuilder provides custom way to create a formatter. It is Case Insensitive, Nov , nov and NOV will be treated as same.

DateTimeFormatter f = new DateTimeFormatterBuilder().parseCaseInsensitive()
        .append(DateTimeFormatter.ofPattern("yyyy-MMM-dd")).toFormatter();
try {
    LocalDate datetime = LocalDate.parse(oldDate, f);
    System.out.println(datetime); // 2019-11-12
} catch (DateTimeParseException e) {
     // Exception handling message/mechanism/logging as per company standard
}

Below is a class which will accomplish the very basics of what you want to do when reading data from a MySQL database into a JTable in Java.

import java.awt.*;
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;

public class TableFromMySqlDatabase extends JFrame
{
    public TableFromMySqlDatabase()
    {
        ArrayList columnNames = new ArrayList();
        ArrayList data = new ArrayList();

        //  Connect to an MySQL Database, run query, get result set
        String url = "jdbc:mysql://localhost:3306/yourdb";
        String userid = "root";
        String password = "sesame";
        String sql = "SELECT * FROM animals";

        // Java SE 7 has try-with-resources
        // This will ensure that the sql objects are closed when the program 
        // is finished with them
        try (Connection connection = DriverManager.getConnection( url, userid, password );
            Statement stmt = connection.createStatement();
            ResultSet rs = stmt.executeQuery( sql ))
        {
            ResultSetMetaData md = rs.getMetaData();
            int columns = md.getColumnCount();

            //  Get column names

In the NetBeans IDE which you are using - you will need to add the MySQL JDBC Driver in Project Properties as I display here:

Otherwise the code will throw an SQLException stating that the driver cannot be found.

Now in my example, yourdb is the name of the database and animals is the name of the table that I am performing a query against.

Here is what will be output:

Parting note:

You stated that you were a novice and needed some help understanding some of the basic classes and concepts of Java. I will list a few here, but remember you can always browse the docs on Oracle's site.

• ArrayList
• Vector
• Try-with-resources statement

Use single quote with single char as:

char ch = 'a';

here 'a' is a char constant and is equal to the ASCII value of char a.

Use double quote with strings as:

char str[] = "foo";

here "foo" is a string literal.

Its okay to use "a" but its not okay to use 'foo'

I cam up with a recursive solution:

def sumDigits(num):
#   print "evaluating:", num
  if num < 10:
    return num

  # solution 1
#   res = num/10
#   rem = num%10
#   print "res:", res, "rem:", rem
#   return sumDigits(res+rem)

    # solution 2
  arr = [int(i) for i in str(num)]
  return sumDigits(sum(arr))

# print(sumDigits(1))
# print(sumDigits(49))
print(sumDigits(439230))
# print(sumDigits(439237))

Date long getTime() returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

//test if date1 is before date2
if(date1.getTime() < date2.getTime()) {
....
}

from @Adam Rosenfield's answer, the formatting string of fscanf would be changed like below:

"%4095[^\r\n]%n%*[\n\r]"

it will work in osx, linux, windows line endings.

I'm using RHEL 7.4 with NGINX 1.13.8 and if I do the same with sudo, it works Ok:

sudo systemctl status nginx.service

Just make sure whoever wants to use nginx.service has execute permissions to it.

I had the same issue. And the files that I needed to be committed were never declared in the .gitignore file as well.

In my case adding the files forcefully using the -f flag elevated to staging and fixed the issue.

git add -f <path to file>

        combo1.DisplayMember = "Text";
        combo1.ValueMember = "Value";   
        combo1.Items.Add(new { Text = "someText"), Value = "someValue") });
        dynamic item = combo1.Items[combo1.SelectedIndex];
        var itemValue = item.Value;
        var itemText = item.Text;

Unfortunatly "combo1.SelectedValue" does not work, i did not want to bind my combobox with any source, so i came up with this solution. Maybe it will help someone.

I had the same problem in VS2008. In my case it was solved via solution-rebuild.

The code is correct so I'm guessing that you are using an older JDK. The javadoc for that method says it has been there since 1.6. At the command line type:

java -version

I'm guessing that you are not running 1.6

First of all, this what is written in documentation. I think it is one of your class fields, not the main one - and how you want deserialiser to construct it back w/o parameterless construction ?

I think there is a workaround to make constructor private.

struct a{
 int x;

 struct son{
  a* _parent;
  void test(){
   _parent->x=1; //success
  }
 }_son;

 }_a;

int main(){
 _a._son._parent=&_a;
 _a._son.test();
}

Reference example.

The need for C++ delegate implementations are a long lasting embarassment to the C++ community. Every C++ programmer would love to have them, so they eventually use them despite the facts that:

1. std::function() uses heap operations (and is out of reach for serious embedded programming).

2. All other implementations make concessions towards either portability or standard conformity to larger or lesser degrees (please verify by inspecting the various delegate implementations here and on codeproject). I have yet to see an implementation which does not use wild reinterpret_casts, Nested class "prototypes" which hopefully produce function pointers of the same size as the one passed in by the user, compiler tricks like first forward declare, then typedef then declare again, this time inheriting from another class or similar shady techniques. While it is a great accomplishment for the implementers who built that, it is still a sad testimoney on how C++ evolves.

3. Only rarely is it pointed out, that now over 3 C++ standard revisions, delegates were not properly addressed. (Or the lack of language features which allow for straightforward delegate implementations.)

4. With the way C++11 lambda functions are defined by the standard (each lambda has anonymous, different type), the situation has only improved in some use cases. But for the use case of using delegates in (DLL) library APIs, lambdas alone are still not usable. The common technique here, is to first pack the lambda into a std::function and then pass it across the API.

os.path.relpath:

Return a relative filepath to path either from the current directory or from an optional start point.

>>> from os.path import relpath
>>> relpath('/usr/var/log/', '/usr/var')
'log'
>>> relpath('/usr/var/log/', '/usr/var/sad/')
'../log'

So, if relative path starts with '..' - it means that the second path is not descendant of the first path.

In Python3 you can use PurePath.relative_to:

Python 3.5.1 (default, Jan 22 2016, 08:54:32)
>>> from pathlib import Path

>>> Path('/usr/var/log').relative_to('/usr/var/log/')
PosixPath('.')

>>> Path('/usr/var/log').relative_to('/usr/var/')
PosixPath('log')

>>> Path('/usr/var/log').relative_to('/etc/')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib/python3.5/pathlib.py", line 851, in relative_to
    .format(str(self), str(formatted)))
ValueError: '/usr/var/log' does not start with '/etc'

All you have to do is copy the cv2.pyd file from the x86 folder (C:\opencv\build\python\2.7\x86\ for example) to C:\Python27\Lib\site-packages\ , not from the x64 folder.

Hope that help you.

Add a listener to the underlying Document, which is automatically created for you.

// Listen for changes in the text
textField.getDocument().addDocumentListener(new DocumentListener() {
  public void changedUpdate(DocumentEvent e) {
    warn();
  }
  public void removeUpdate(DocumentEvent e) {
    warn();
  }
  public void insertUpdate(DocumentEvent e) {
    warn();
  }

  public void warn() {
     if (Integer.parseInt(textField.getText())<=0){
       JOptionPane.showMessageDialog(null,
          "Error: Please enter number bigger than 0", "Error Message",
          JOptionPane.ERROR_MESSAGE);
     }
  }
});

It's as simple as this :

$array[$key];

None of the answers work for all output types the same way and others focus on figures plottet within the code chunk and not external images.

The include_graphics() function provides an easy solution. The only argument is the name of the file (with the relative path if it's in a subfolder). By setting echo to FALSE and fig.align=center you get the wished result.

```{r, echo=FALSE, fig.align='center'}
include_graphics("image.jpg")
```

Use material-design-icons-iconfont

Full disclosure, I'm the author of this package

Google's material-design-icons project is on low maintenance and out of date for a while. There's a gap between the version in https://material.io/icons/ and the version in material-design-icons.

I've created material-design-icons-iconfont to address these major issues:

• material-design-icons jams npm install - all irrelevant svg/xml/... files has been removed
• Font files are always up-to-date straight from Google Fonts CDN
• Support for scss

Install via npm

npm install material-design-icons-iconfont --save

It depends on how you pack your web application (webpack/gulp/bower/...), you'll need to import the .css/.scss file (and might change the relative fonts path)

Import Using SCSS

Import in one of your sass files

$material-design-icons-font-path: '~material-design-icons-iconfont/dist/fonts/';
@import '~material-design-icons-iconfont/src/material-design-icons';

Later on, reference your desired icon <i class="material-icons"> + icon-id + </i>

<i class="material-icons">contact_support</i>

• read the full instructions on material-design-icons-iconfont for more import methods

Demo page

It comes with a light demo page to assist searching and copy-pasting fonts

ifconfig | grep 'inet ' | grep -v '127.0.0.1' | awk '{print $2}'

For file names:

var cleanFileName = string.Join("", fileName.Split(Path.GetInvalidFileNameChars()));

For full paths:

var cleanPath = string.Join("", path.Split(Path.GetInvalidPathChars()));

Note that if you intend to use this as a security feature, a more robust approach would be to expand all paths and then verify that the user supplied path is indeed a child of a directory the user should have access to.

Profile pictures are scaled down to 125x125 on the facebook sever when they're uploaded, so as far as I know you can't get pictures bigger than that. How big is the picture you're getting?

I had this problem today testing a method that converted an object that contained a Map to a JSON string. I assume Eclipse and the Maven surefire plugin were using different JREs which had different implementations of HashMap ordering or something, which caused the tests run through Eclipse to pass and the tests run through surefire to fail (assertEquals failed). The easiest solution was to use an implementation of Map that had reliable ordering.

if (value == "") {
  // it is empty
}

[[NSDate date] timeIntervalSince1970];

It returns the number of seconds since epoch as a double. I'm almost sure you can access the milliseconds from the fractional part.

Try this in input field:

[readonly]="true"

Hope, this will work.

In pycharm I wrote the code for accessing the IP Camera like:

import cv2

cap=VideoCapture("rtsp://user_name:password@IP_address:port_number")

ret, frame=cap.read()

You will need to replace user_name, password, IP and port with suitable values

The previous posts about forming POST requests are largely correct (add the parameters to the body, not the URL). But if there is any chance of the input data containing any reserved characters (e.g. spaces, ampersand, plus sign), then you will want to handle these reserved characters. Namely, you should percent-escape the input.

//create body of the request

NSString *userid = ...
NSString *encodedUserid = [self percentEscapeString:userid];
NSString *postString    = [NSString stringWithFormat:@"userid=%@", encodedUserid];
NSData   *postBody      = [postString dataUsingEncoding:NSUTF8StringEncoding];

//initialize a request from url

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPBody:postBody];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

//initialize a connection from request, any way you want to, e.g.

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

Where the precentEscapeString method is defined as follows:

- (NSString *)percentEscapeString:(NSString *)string
{
    NSString *result = CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,
                                                                                 (CFStringRef)string,
                                                                                 (CFStringRef)@" ",
                                                                                 (CFStringRef)@":/?@!$&'()*+,;=",
                                                                                 kCFStringEncodingUTF8));
    return [result stringByReplacingOccurrencesOfString:@" " withString:@"+"];
}

Note, there was a promising NSString method, stringByAddingPercentEscapesUsingEncoding (now deprecated), that does something very similar, but resist the temptation to use that. It handles some characters (e.g. the space character), but not some of the others (e.g. the + or & characters).

The contemporary equivalent is stringByAddingPercentEncodingWithAllowedCharacters, but, again, don't be tempted to use URLQueryAllowedCharacterSet, as that also allows + and & pass unescaped. Those two characters are permitted within the broader "query", but if those characters appear within a value within a query, they must escaped. Technically, you can either use URLQueryAllowedCharacterSet to build a mutable character set and remove a few of the characters that they've included in there, or build your own character set from scratch.

For example, if you look at Alamofire's parameter encoding, they take URLQueryAllowedCharacterSet and then remove generalDelimitersToEncode (which includes the characters #, [, ], and @, but because of a historical bug in some old web servers, neither ? nor /) and subDelimitersToEncode (i.e. !, $, &, ', (, ), *, +, ,, ;, and =). This is correct implementation (though you could debate the removal of ? and /), though pretty convoluted. Perhaps CFURLCreateStringByAddingPercentEscapes is more direct/efficient.

I had the exact same problem with my instance. My problem was that I forgot to allow port 80 access to the server. Maybe that's your issue as well?

Check with your WHM and make sure that port is open for the IP address of your site,

When you call a Linq statement like this:

// x = new List<string>();
var count = x.Count(s => s.StartsWith("x"));

You are actually using an extension method in the System.Linq namespace, so what the compiler translates this into is:

var count = Enumerable.Count(x, s => s.StartsWith("x"));

So the error you are getting above is because the first parameter, source (which would be x in the sample above) is null.

You can include the branch to track when setting up remotes, to keep things working as you might expect:

git remote add --track master origin [email protected]:group/project.git   # git
git remote add --track master origin [email protected]:group/project.git   # git w/IP
git remote add --track master origin http://github.com/group/project.git   # http
git remote add --track master origin http://172.16.1.100/group/project.git # http w/IP
git remote add --track master origin /Volumes/Git/group/project/           # local
git remote add --track master origin G:/group/project/                     # local, Win

This keeps you from having to manually edit your git config or specify branch tracking manually.

I just wondered, why col-xs-6 did not work for me but then I found the answer in the Bootstrap 4 documentation. The class prefix for extra small devices is now col- while in the previous versions it was col-xs.

https://getbootstrap.com/docs/4.1/layout/grid/#grid-options

Bootstrap 4 dropped all col-xs-* classes, so use col-* instead. For example col-xs-6 replaced by col-6.

From the standard

7.5.2 Element identifiers: the id and class attributes

Attribute definitions

id = name [CS]
This attribute assigns a name to an element. This name must be unique in a document.

class = cdata-list [CS]
This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters.

Yes, just put a space between them.

When you go to the MySQL download page, choose the platform "Microsoft Windows". Then download the "Windows (x86, xx-bit), ZIP Archive" (be sure to select the one with size over 140M.

The binaries will be in the "bin" folder.

I understand that this is not just the client binaries, but at least you don't have to install and setup the entire server.

The REST API for Dropbox, Twitter, Google Web Services and Facebook all uses underscores.

I came across this error today when I wanted to add a new column like this

df_temp['REMARK_TYPE'] = df.REMARK.apply(lambda v: 1 if str(v)!='nan' else 0)

I wanted to process the REMARK column of df_temp to return 1 or 0. However I typed wrong variable with df. And it returned error like this:

----> 1 df_temp['REMARK_TYPE'] = df.REMARK.apply(lambda v: 1 if str(v)!='nan' else 0)

ValueError: cannot reindex from a duplicate axis

As you can see it, the right code should be

df_temp['REMARK_TYPE'] = df_temp.REMARK.apply(lambda v: 1 if str(v)!='nan' else 0)

Because df and df_temp have a different number of rows. So it returned ValueError: cannot reindex from a duplicate axis.

Hope you can understand it and my answer can help other people to debug their code.

BufferedReader can't wrap an InputStream directly. It wraps another Reader. In this case you'd want to do something like:

BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));

Try this query:

SELECT id, COUNT( payer_email ) `tot`
FROM paypal_ipn_orders
GROUP BY id
HAVING `tot` >1

Does it help?

To link to a form you need:

Form2 form2 = new Form2();
        form2.show();

this.hide();

then hide the previous form

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

I'm not sure whether it's a good idea to use integers at all. Some numbers might contain special characters (# as part of the extension for example) which you should be able to handle too. So I would suggest using varchars instead.

func sum(array : [Int]) -> Int{
    var sum = 0
    array.forEach { (item) in
        sum = item + sum
    }
    return sum
}
func susetNumbers(array :[Int], target : Int, subsetArray: [Int],result : inout [[Int]]) -> [[Int]]{
    let s = sum(array: subsetArray)
    if(s == target){
        print("sum\(subsetArray) = \(target)")
        result.append(subsetArray)
    }
    for i in 0..<array.count{
        let n = array[i]
        let remaning = Array(array[(i+1)..<array.count])
        susetNumbers(array: remaning, target: target, subsetArray: subsetArray + [n], result: &result)
        
    }
    return result
}

 var resultArray = [[Int]]()
    let newA = susetNumbers(array: [1,2,3,4,5], target: 5, subsetArray: [],result:&resultArray)
    print(resultArray)

Try This

SELECT Title  from #Movies
    SELECT CASE WHEN Title = '' THEN 'No Title' ELSE Title END AS Titile from #Movies

OR

SELECT [Id], [CategoryId], ISNULL(nullif(Title,''),'No data') as Title, [Director], [DateReleased] FROM #Movies

The order in which you use middleware in Express matters: middleware declared earlier will get called first, and if it can handle a request, any middleware declared later will not get called.

If express.static is handling the request, you need to move your middleware up:

// need cookieParser middleware before we can do anything with cookies
app.use(express.cookieParser());

// set a cookie
app.use(function (req, res, next) {
  // check if client sent cookie
  var cookie = req.cookies.cookieName;
  if (cookie === undefined) {
    // no: set a new cookie
    var randomNumber=Math.random().toString();
    randomNumber=randomNumber.substring(2,randomNumber.length);
    res.cookie('cookieName',randomNumber, { maxAge: 900000, httpOnly: true });
    console.log('cookie created successfully');
  } else {
    // yes, cookie was already present 
    console.log('cookie exists', cookie);
  } 
  next(); // <-- important!
});

// let static middleware do its job
app.use(express.static(__dirname + '/public'));

Also, middleware needs to either end a request (by sending back a response), or pass the request to the next middleware. In this case, I've done the latter by calling next() when the cookie has been set.

Update

As of now the cookie parser is a seperate npm package, so instead of using

app.use(express.cookieParser());

you need to install it separately using npm i cookie-parser and then use it as:

const cookieParser = require('cookie-parser');
app.use(cookieParser());

Make sure you Double-Check that the version you refer to in the child-pom is the same as that in the parent-pom. For me, I'd bumped version in the parent and had it as 3.1.0.0-RELEASE, but in the child-pom, I was still referring to the previous version via relativePath, and had it defined as 2.0.0.0-SNAPSHOT. It did not make any difference if I included just the parent directory, or had the "pom.xml" appended to the directory:

    <parent>        
    <artifactId>eric-project-parent</artifactId>
    <groupId>com.eric.common</groupId>
     <!-- Should be 3.1.0.0-RELEASE -->
    <version>2.0.0.0-SNAPSHOT</version>     
    <relativePath>
                ../../EricParentAsset/projects/eric-project-parent</relativePath>           
</parent>

The following will print the line matching TERMINATE till the end of the file:

sed -n -e '/TERMINATE/,$p'

Explained: -n disables default behavior of sed of printing each line after executing its script on it, -e indicated a script to sed, /TERMINATE/,$ is an address (line) range selection meaning the first line matching the TERMINATE regular expression (like grep) to the end of the file ($), and p is the print command which prints the current line.

This will print from the line that follows the line matching TERMINATE till the end of the file:
(from AFTER the matching line to EOF, NOT including the matching line)

sed -e '1,/TERMINATE/d'

Explained: 1,/TERMINATE/ is an address (line) range selection meaning the first line for the input to the 1st line matching the TERMINATE regular expression, and d is the delete command which delete the current line and skip to the next line. As sed default behavior is to print the lines, it will print the lines after TERMINATE to the end of input.

Edit:

If you want the lines before TERMINATE:

sed -e '/TERMINATE/,$d'

And if you want both lines before and after TERMINATE in 2 different files in a single pass:

sed -e '1,/TERMINATE/w before
/TERMINATE/,$w after' file

The before and after files will contain the line with terminate, so to process each you need to use:

head -n -1 before
tail -n +2 after

Edit2:

IF you do not want to hard-code the filenames in the sed script, you can:

before=before.txt
after=after.txt
sed -e "1,/TERMINATE/w $before
/TERMINATE/,\$w $after" file

But then you have to escape the $ meaning the last line so the shell will not try to expand the $w variable (note that we now use double quotes around the script instead of single quotes).

I forgot to tell that the new line is important after the filenames in the script so that sed knows that the filenames end.

Edit: 2016-0530

Sébastien Clément asked: "How would you replace the hardcoded TERMINATE by a variable?"

You would make a variable for the matching text and then do it the same way as the previous example:

matchtext=TERMINATE
before=before.txt
after=after.txt
sed -e "1,/$matchtext/w $before
/$matchtext/,\$w $after" file

to use a variable for the matching text with the previous examples:

## Print the line containing the matching text, till the end of the file:
## (from the matching line to EOF, including the matching line)
matchtext=TERMINATE
sed -n -e "/$matchtext/,\$p"

## Print from the line that follows the line containing the 
## matching text, till the end of the file:
## (from AFTER the matching line to EOF, NOT including the matching line)
matchtext=TERMINATE
sed -e "1,/$matchtext/d"

## Print all the lines before the line containing the matching text:
## (from line-1 to BEFORE the matching line, NOT including the matching line)
matchtext=TERMINATE
sed -e "/$matchtext/,\$d"

The important points about replacing text with variables in these cases are:

1. Variables ($variablename) enclosed in single quotes ['] won't "expand" but variables inside double quotes ["] will. So, you have to change all the single quotes to double quotes if they contain text you want to replace with a variable.
2. The sed ranges also contain a $ and are immediately followed by a letter like: $p, $d, $w. They will also look like variables to be expanded, so you have to escape those $ characters with a backslash [\] like: \$p, \$d, \$w.

I think you're looking for;

  string[] skus = myLines.Select(x => x.Sku).ToArray();

However, if you're going to iterate over the sku's in subsequent code I recommend not using the ToArray() bit as it forces the queries execution prematurely and makes the applications performance worse. Instead you can just do;

  var skus = myLines.Select(x => x.Sku); // produce IEnumerable<string>

  foreach (string sku in skus) // forces execution of the query

I tried pasting Endoro's command (Thanks Endoro) directly into the command prompt to add a prefix to files but encountered an error. Solution was to reduce %% to %, so:

for /f "delims=" %i in ('dir /b /a-d *.*') do ren "%~i" "Service.Enviro.%~ni%~xi"

I also recommend the SSH SFTP Updater Support plugin. Just solved all my problems too...especially in regards to getting plugins to delete through the admin. Just install it in the usual way, and the next time you're prompted by WordPress for FTP details, there'll be extra fields for you to copy/paste your private SSH key or upload your PEM file.

Only problem I have is in getting it to remember the key (tried both methods). Don't like the idea of having to find and enter it every time I need to delete a plugin. But at least it's a solid fix for now.

check, if this works for you.

Try adding 2 spaces (or a backslash \) after the first line:

[Name of link](url)
My line of text\

Visually:

[Name of link](url)<space><space>
My line of text\

Output:

<p><a href="url">Name of link</a><br>

Do not use arrow function to create functional components.

Do as one of the examples below:

function MyComponent(props) {
  const [states, setStates] = React.useState({ value: '' });

  return (
    <input
      type="text"
      value={states.value}
      onChange={(event) => setStates({ value: event.target.value })}
    />
  );
}

Or

//IMPORTANT: Repeat the function name

const MyComponent = function MyComponent(props) { 
  const [states, setStates] = React.useState({ value: '' });

  return (
    <input
      type="text"
      value={states.value}
      onChange={(event) => setStates({ value: event.target.value })}
    />
  );
};

If you have problems with "ref" (probably in loops), the solution is to use forwardRef():

// IMPORTANT: Repeat the function name
// Add the "ref" argument to the function, in case you need to use it.

const MyComponent = React.forwardRef( function MyComponent(props, ref) {
  const [states, setStates] = React.useState({ value: '' });

  return (
    <input
      type="text"
      value={states.value}
      onChange={(event) => setStates({ value: event.target.value })}
    />
  );
});

If you're looking to turn the items in a list into a big long string, do this: String.Join("", myList). Some older versions of the framework don't allow you to pass an IEnumerable as the second parameter, so you may need to convert your list to an array by calling .ToArray().

With recent browser support of "Clear-Site-Data" headers, you can clear different types of data: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Clear-Site-Data

header('Clear-Site-Data: "cache", "cookies", "storage", "executionContexts"');

There are a lot of good reasons in other answers but all seem to forget that for_each allows you to use reverse or pretty much any custom iterator when for loop always starts with begin() iterator.

Example with reverse iterator:

std::list<int> l {1,2,3};
std::for_each(l.rbegin(), l.rend(), [](auto o){std::cout<<o;});

Example with some custom tree iterator:

SomeCustomTree<int> a{1,2,3,4,5,6,7};
auto node = a.find(4);
std::for_each(node.breadthFirstBegin(), node.breadthFirstEnd(), [](auto o){std::cout<<o;});

function isPrevDate() {
    alert("startDate is " + Startdate);
    if(Startdate.length != 0 && Startdate !='') {
        var start_date = Startdate.split('-');
        alert("Input date: "+ start_date);
        start_date=start_date[1]+"/"+start_date[2]+"/"+start_date[0];
        alert("start date arrray format " + start_date);
        var a = new Date(start_date);
        //alert("The date is a" +a);
        var today = new Date();
        var day = today.getDate();
        var mon = today.getMonth()+1;
        var year = today.getFullYear();
        today = (mon+"/"+day+"/"+year);
        //alert(today);
        var today = new Date(today);
        alert("Today: "+today.getTime());
        alert("a : "+a.getTime());
        if(today.getTime() > a.getTime() )
        {
            alert("Please select Start date in range");
            return false;
        } else {
            return true;
        }
    }
}

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

Just use the command S <- S[,-2] to remove the second column. Similarly to delete a row, for example, to delete the second row use S <- S[-2,].

You can also drag a tap gesture recogniser to the image view in Storyboard. Then create an action by ctrl + drag to the code.

In Bootstrap 4, if you want to do something like this:

    Mobile  |   Desktop
-----------------------------
    A       |       A
    C       |   B       C
    B       |       D
    D       |

You need to reverse the order of B then C then apply order-{breakpoint}-first to B. And apply two different settings, one that will make them share the same cols and other that will make them take the full width of the 12 cols:

• Smaller screens: 12 cols to B and 12 cols to C

• Larger screens: 12 cols between the sum of them (B + C = 12)

Like this

<div class='row no-gutters'>
    <div class='col-12'>
        A
    </div>
    <div class='col-12'>
        <div class='row no-gutters'>
            <div class='col-12 col-md-6'>
                C
            </div>
            <div class='col-12 col-md-6 order-md-first'>
                B
            </div>
        </div>
    </div>
    <div class='col-12'>
        D
    </div>
</div>

Using LINQ:

arr = (arr ?? Enumerable.Empty<string>()).Concat(new[] { newitem }).ToArray();

I like using this as it is a one-liner and very convenient to embed in a switch statement, a simple if-statement, or pass as argument.

EDIT:

Some people don't like new[] { newitem } because it creates a small, one-item, temporary array. Here is a version using Enumerable.Repeat that does not require creating any object (at least not on the surface -- .NET iterators probably create a bunch of state machine objects under the table).

arr = (arr ?? Enumerable.Empty<string>()).Concat(Enumerable.Repeat(newitem,1)).ToArray();

And if you are sure that the array is never null to start with, you can simplify it to:

arr.Concat(Enumerable.Repeat(newitem,1)).ToArray();

Notice that if you want to add items to a an ordered collection, List is probably the data structure you want, not an array to start with.

The font-min-size and font-max-size CSS properties were removed from the CSS Fonts Module Level 4 specification (and never implemented in browsers AFAIK). And the CSS Working Group replaced the CSS examples with font-size: clamp(...) which doesn't have the greatest browser support yet so we'll have to wait for browsers to support it. See example in https://developer.mozilla.org/en-US/docs/Web/CSS/clamp#Examples.
