You need to define a resource reference in your application and then map that logical resource reference to the physical resource (data source) during deployment.

In your web.xml, add the following configuration (modifying the names and properties as appropriate):

<resource-ref>
    <description>Resource reference to my database</description>
    <res-ref-name>jdbc/MyDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

Then, during application deployment, WAS will prompt you to map this resource reference (jdbc/MyDB) to the data source you created in WAS.

In your code, you can obtain the DataSource similar to how you've shown it in your example; however, the JNDI name you'll use to look it up should actually be the resource reference's name you defined (res-ref-name), rather than the JNDI name of the physical data source. Also, you'll need to prefix the res-ref-name with the application naming context (java:comp/env/).

Context ctx = new InitialContext();
DataSource dataSource = (DataSource) ctx.lookup("java:comp/env/jdbc/MyDB");

You would use it if you are using RenderAction in any of your views, usually to render a partial view.

The reason for marking it with [ChildActionOnly] is that you need the controller method to be public so you can call it with RenderAction but you don't want someone to be able to navigate to a URL (e.g. /Controller/SomeChildAction) and see the results of that action directly.

ExtendOffice.com offers a VBA solution that worked for me in Excel 2016. Here's my description of the steps. I included additional details to make it easier. I also modified the VBA code slightly. If this doesn't work for you, retry the steps or check out the instructions on the ExtendOffice page.

1. Add data validation to a cell (or range of cells). Allow = List. Source = [the range with the values you want for the auto-complete / drop-down]. Click OK. You should now have a drop-down but with a weak auto-complete feature.

   

2. With a cell containing your newly added data validation, insert an ActiveX combo box (NOT a form control combo box). This is done from the Developer ribbon. If you don't have the Developer ribbon you will need to add it from the Excel options menu.

   

3. From the Developer tab in the Controls section, click "Design Mode". Select the combo box you just inserted. Then in the same ribbon section click "Properties". In the Properties window, change the name of the combo box to "TempComboBox".

   

4. Press ALT + F11 to go to the Visual Basic Editor. On the left-hand side, double click the worksheet with your data validation to open the code for that sheet. Copy and paste the following code onto the sheet. NOTE: I modified the code slightly so that it works even with Option Explicit enabled at the top of the sheet.

   Option Explicit
   
   Private Sub Worksheet_SelectionChange(ByVal target As Range)
   'Update by Extendoffice: 2018/9/21
   ' Update by Chris Brackett 2018-11-30
   
   Dim xWs As Worksheet
   Set xWs = Application.ActiveSheet
   
   On Error Resume Next
   
   Dim xCombox As OLEObject
   Set xCombox = xWs.OLEObjects("TempCombo")
   
   ' Added this to auto select all text when activating the combox box.
   xCombox.SetFocus
   
   With xCombox
       .ListFillRange = vbNullString
       .LinkedCell = vbNullString
       .Visible = False
   End With
   
   
   Dim xStr As String
   Dim xArr
   
   
   If target.Validation.Type = xlValidateList Then
       ' The target cell contains Data Validation.
   
       target.Validation.InCellDropdown = False
   
   
       ' Cancel the "SelectionChange" event.
       Dim Cancel As Boolean
       Cancel = True
   
   
       xStr = target.Validation.Formula1
       xStr = Right(xStr, Len(xStr) - 1)
   
       If xStr = vbNullString Then Exit Sub
   
       With xCombox
           .Visible = True
           .Left = target.Left
           .Top = target.Top
           .Width = target.Width + 5
           .Height = target.Height + 5
           .ListFillRange = xStr
   
           If .ListFillRange = vbNullString Then
               xArr = Split(xStr, ",")
               Me.TempCombo.List = xArr
           End If
   
           .LinkedCell = target.Address
   
       End With
   
       xCombox.Activate
       Me.TempCombo.DropDown
   
   End If
   End Sub
   
   Private Sub TempCombo_KeyDown( _
                   ByVal KeyCode As MSForms.ReturnInteger, _
                   ByVal Shift As Integer)
       Select Case KeyCode
           Case 9  ' Tab key
               Application.ActiveCell.Offset(0, 1).Activate
           Case 13 ' Pause key
               Application.ActiveCell.Offset(1, 0).Activate
       End Select
   End Sub
   

5. Make sure the the "Microsoft Forms 2.0 Object Library" is referenced. In the Visual Basic Editor, go to Tools > References, check the box next to that library (if not already checked) and click OK. To verify that it worked, go to Debug > Compile VBA Project.

6. Finally, save your project and click in a cell with the data validation you added. You should see a combo box with a drop-down list of suggestions that updates with each letter you type.

I found this solution in this article

.parent-element {
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  transform-style: preserve-3d;
}

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

It work like a charm if the height of element is not fixed.

I had the same issue and I have found a library that does the job : https://github.com/pleerock/class-transformer.

It works like this :

let jsonObject = response.json() as Object;
let fooInstance = plainToClass(Models.Foo, jsonObject);
return fooInstance;

It supports nested childs but you have to decorate your class's member.

there is a way you can pass more than one parameter. You can pass "to" as object instead of string.

// your route setup
<Route path="/category/:catId" component={Category} / >

// your link creation
const newTo = { 
  pathname: "/category/595212758daa6810cbba4104", 
  param1: "Par1" 
};
// link to the "location"
// see (https://reacttraining.com/react-router/web/api/location)
<Link to={newTo}> </Link>

// In your Category Component, you can access the data like this
this.props.match.params.catId // this is 595212758daa6810cbba4104 
this.props.location.param1 // this is Par1

Part One - Polyfill

For browsers that haven't implemented it, a polyfill for array.find. Courtesy of MDN.

if (!Array.prototype.find) {
  Array.prototype.find = function(predicate) {
    if (this == null) {
      throw new TypeError('Array.prototype.find called on null or undefined');
    }
    if (typeof predicate !== 'function') {
      throw new TypeError('predicate must be a function');
    }
    var list = Object(this);
    var length = list.length >>> 0;
    var thisArg = arguments[1];
    var value;

    for (var i = 0; i < length; i++) {
      value = list[i];
      if (predicate.call(thisArg, value, i, list)) {
        return value;
      }
    }
    return undefined;
  };
}

Part Two - Interface

You need to extend the open Array interface to include the find method.

interface Array<T> {
    find(predicate: (search: T) => boolean) : T;
}

When this arrives in TypeScript, you'll get a warning from the compiler that will remind you to delete this.

Part Three - Use it

The variable x will have the expected type... { id: number }

var x = [{ "id": 1 }, { "id": -2 }, { "id": 3 }].find(myObj => myObj.id < 0);

Let's say you have the following directory structure where you want to generate javadocs on file1.java and file2.java (package com.test), with the javadocs being placed in C:\javadoc\test:

C:\
|
+--javadoc\
|  |
|  +--test\
|
+--projects\
   |
   +--com\
      |
      +--test\
         |
         +--file1.java
         +--file2.java

In the command terminal, navigate to the root of your package: C:\projects. If you just want to generate the standard javadocs on all the java files inside the project, run the following command (for multiple packages, separate the package names by spaces):

C:\projects> javadoc -d [path to javadoc destination directory] [package name]

C:\projects> javadoc -d C:\javadoc\test com.test

If you want to run javadocs from elsewhere, you'll need to specify the sourcepath. For example, if you were to run javadocs in in C:\, you would modify the command as such:

C:\> javadoc -d [path to javadoc destination directory] -sourcepath [path to package directory] [package name]

C:\> javadoc -d C:\javadoc\test -sourcepath C:\projects com.test

If you want to run javadocs on only selected .java files, then add the source filenames separated by spaces (you can use an asterisk (*) for a wildcard). Make sure to include the path to the files:

C:\> javadoc -d [path to javadoc destination directory] [source filenames]

C:\> javadoc -d C:\javadoc\test C:\projects\com\test\file1.java

In XAMPP installation directory, open %XAMPP_HOME%/php/php.ini file. Uncomment the following line: extension=php_curl.dll

PS: If that doesn't work then check whether %XAMPP_HOME%/php/ext/php_curl.dll file exist or not.

I was facing same issue, tried restarting my server, reopening editor but computer restart did the magic.

P.S: I was facing issue on a windows machine and issue occurred when I moved module into a new folder.

Read : 101 LINQ Samples in that LINQ - Grouping Operators from Microsoft MSDN site

var x = from t in types  group t by t.Type
         into grp    
         select new { type = grp.key, count = grp.Count() };

forsingle object make use of stringbuilder and append it that will do or convert this in form of dictionary

    // fordictionary 
  var x = (from t in types  group t by t.Type
     into grp    
     select new { type = grp.key, count = grp.Count() })
   .ToDictionary( t => t.type, t => t.count); 

   //for stringbuilder not sure for this 
  var x = from t in types  group t by t.Type
         into grp    
         select new { type = grp.key, count = grp.Count() };
  StringBuilder MyStringBuilder = new StringBuilder();

Open Notepad and write this

@echo off
:A
Cls
echo MESSENGER
set /p n=User:
set /p m=Message:
net send %n% %m%
Pause
Goto A

and then save as "Messenger.bat" and close the Notepad
Step 1:

when you open that saved notepad file it will open as a file Messenger command prompt with this details.

Messenger
User:

after "User" write the ip of the computer you want to contact and then press enter.

Find end position of file:

f = open("file.txt","r")
f.seek(0,2) #Jumps to the end
f.tell()    #Give you the end location (characters from start)
f.seek(0)   #Jump to the beginning of the file again

Then you can to:

if line == '' and f.tell() == endLocation:
   break

Use an "Or"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where (CPaymentType='Check' Or CPaymentType='Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

or an "IN"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where CPaymentType IN ('Check', 'Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

$ git clone --bare https://github.com/example

This command will make the new "example" directory itself the $GIT_DIR (instead of example/.git). Also the branch heads at the remote are copied directly to corresponding local branch heads, without mapping. When this option is used, neither remote-tracking branches nor the related configuration variables are created.

$ git clone --mirror https://github.com/example

As with a bare clone, a mirrored clone includes all remote branches and tags, but all local references (including remote-tracking branches, notes etc.) will be overwritten each time you fetch, so it will always be the same as the original repository.

$ mysqladmin variables | grep sock

Try this instead, this will output the demanded result, getting rid of unrelated info.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

using (var cmd = new SqlCommand("SELECT EmpName FROM [Employee] WHERE EmpID = @id", con))

put [] around table name ;)

"Best" helpdesk system is very subjective, of course, but I recommend Request Tracker (aka RT).

It has a default workflow built in, but is easily configured for alternate workflows using the "Scrips" and templates. Very extensible if you want.

If you connect with the server, then you can get a return code from it, otherwise it will fail and you get a 0. So if you try to connect to "www.google.com/lksdfk" you will get a return code of 400, if you go directly to google.com, you will get 302 (and then 200 if you forward to the next page... well I do because it forwards to google.com.br, so you might not get that), and if you go to "googlecom" you will get a 0 (host no found), so with the last one, there is nobody to send a code back.

Tested using the code below.

<?php

$html_brand = "www.google.com";
$ch = curl_init();

$options = array(
    CURLOPT_URL            => $html_brand,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER         => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_ENCODING       => "",
    CURLOPT_AUTOREFERER    => true,
    CURLOPT_CONNECTTIMEOUT => 120,
    CURLOPT_TIMEOUT        => 120,
    CURLOPT_MAXREDIRS      => 10,
);
curl_setopt_array( $ch, $options );
$response = curl_exec($ch); 
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

if ( $httpCode != 200 ){
    echo "Return code is {$httpCode} \n"
        .curl_error($ch);
} else {
    echo "<pre>".htmlspecialchars($response)."</pre>";
}

curl_close($ch);

To diagnose this error quickly drop to a terminal or use the terminal built into Android Studio (accessible on in bottom status bar). Change to the main directory for your PROJECT (where settings.gradle is located).

1.) Check to make sure your settings.gradle includes the subproject. Something like this. This ensures your multi-project build knows about your library sub-project.

include ':apps:App1', ':apps:App2', ':library:Lib1'

Where the text between the colons are sub-directories.

2.) Run the following gradle command just see if Gradle can give you a list of tasks for the library. Use the same qualifier in the settings.gradle definition. This will uncover issues with the Library build script in isolation.

./gradlew :library:Lib1:tasks --info

3.) Make sure the output from the last step listed an "assembleDefault" task. If it didn't make sure the Library is including the Android Library plugin in build.gradle. Like this at the very top.

apply plugin: 'com.android.library'

I know the original poster's question was answered but I believe the answer has evolved over the past year and I think there are multiple reasons for the error. I think this resolution flow should assist those who run into the various issues.

From the documentation:

Dynamic web applications also need static files. That’s usually where the CSS and JavaScript files are coming from. Ideally your web server is configured to serve them for you, but during development Flask can do that as well. Just create a folder called static in your package or next to your module and it will be available at /static on the application.

To generate URLs for static files, use the special 'static' endpoint name:

url_for('static', filename='style.css')

The file has to be stored on the filesystem as static/style.css.

Very simply, and cobbling together some of the great comments here along with my own research into this.

First, check out the local branch you want to tie to your remote branch:

git checkout mybranch

Next:

git branch -u origin/mybranch

where:

git branch -u {remote name}/{branch name}

You should get a message:

"Branch mybranch set up to track remote branch mybranch from origin."

just convert denominator to decimal before division e.g

select col1 / CONVERT(decimal(4,2), col2) from tbl1

Here is my suggestion - it's quite simple as that:

After you changed a Mac which are not the origin one who created the disitribution certificate, you will missing the private key.Just delete the origin certificate and recreate a new one, that works for me~

Here's an example of creating and using an event with C#

using System;

namespace Event_Example
{
    //First we have to define a delegate that acts as a signature for the
    //function that is ultimately called when the event is triggered.
    //You will notice that the second parameter is of MyEventArgs type.
    //This object will contain information about the triggered event.
    public delegate void MyEventHandler(object source, MyEventArgs e);

    //This is a class which describes the event to the class that recieves it.
    //An EventArgs class must always derive from System.EventArgs.
    public class MyEventArgs : EventArgs
    {
        private string EventInfo;
        public MyEventArgs(string Text)
        {
            EventInfo = Text;
        }
        public string GetInfo()
        {
            return EventInfo;
        }
    }

    //This next class is the one which contains an event and triggers it
    //once an action is performed. For example, lets trigger this event
    //once a variable is incremented over a particular value. Notice the
    //event uses the MyEventHandler delegate to create a signature
    //for the called function.
    public class MyClass
    {
        public event MyEventHandler OnMaximum;
        private int i;
        private int Maximum = 10;
        public int MyValue
        {
            get
            {
                return i;
            }
            set
            {
                if(value <= Maximum)
                {
                    i = value;
                }
                else
                {
                    //To make sure we only trigger the event if a handler is present
                    //we check the event to make sure it's not null.
                    if(OnMaximum != null)
                    {
                        OnMaximum(this, new MyEventArgs("You've entered " +
                            value.ToString() +
                            ", but the maximum is " +
                            Maximum.ToString()));
                    }
                }
            }
        }
    }

    class Program
    {
        //This is the actual method that will be assigned to the event handler
        //within the above class. This is where we perform an action once the
        //event has been triggered.
        static void MaximumReached(object source, MyEventArgs e)
        {
            Console.WriteLine(e.GetInfo());
        }

        static void Main(string[] args)
        {
            //Now lets test the event contained in the above class.
            MyClass MyObject = new MyClass();
            MyObject.OnMaximum += new MyEventHandler(MaximumReached);

            for(int x = 0; x <= 15; x++)
            {
                MyObject.MyValue = x;
            }

            Console.ReadLine();
        }
    }
}

Set the JVM memory:

export _JAVA_OPTIONS=-Xmx512M

Using OVER() and LIMIT 1:

SELECT COUNT(1) OVER()
FROM posts 
   INNER JOIN votes ON votes.post_id = posts.id 
GROUP BY posts.id
LIMIT 1;

Working off of Matt's solution, I used the following Compass/SCSS implementation.

@for $i from 1 through 20 {
    li:first-child:nth-last-child( #{$i} ),
    li:first-child:nth-last-child( #{$i} ) ~ li {
      width: calc(100% / #{$i} - 10px);
    }
  }

This allows you to quickly expand the number of items.

Daemon thread is like daemon process which is responsible for managing resources,a daemon thread is created by the Java VM to serve the user threads. example updating system for unix,unix is daemon process. child of daemon thread is always daemon thread,so by default daemon is false.you can check thread as daemon or user by using "isDaemon()" method. so daemon thread or daemon process are basically responsible for managing resources. for example when you starting jvm there is garbage collector running that is daemon thread whose priority is 1 that is lowest,which is managing memory. jvm is alive as long as user thread is alive,u can not kill daemon thread.jvm is responsible to kill daemon threads.

Example using Array.filter:

var str = 'a,b,hi,ma,n,yu';

var strArr = Array.prototype.filter.call(str, eachChar => eachChar !== ',');

I combined several approaches here. I like the idea of the preprocessor and the indexed list.

There's no extra dynamic allocation, and because of the inlining the compiler might be able to optimize the lookup.

typedef NS_ENUM(NSUInteger, FormatType) { FormatTypeJSON = 0, FormatTypeXML, FormatTypeAtom, FormatTypeRSS, FormatTypeCount };

NS_INLINE NSString *FormatTypeToString(FormatType t) {
  if (t >= FormatTypeCount)
    return nil;

#define FormatTypeMapping(value) [value] = @#value

  NSString *table[FormatTypeCount] = {FormatTypeMapping(FormatTypeJSON),
                                      FormatTypeMapping(FormatTypeXML),
                                      FormatTypeMapping(FormatTypeAtom),
                                      FormatTypeMapping(FormatTypeRSS)};

#undef FormatTypeMapping

  return table[t];
}

I can't remember where I came across this script, but I've been using it with XCloner to move my WP multisites.

There is only workaround for the issue you are facing.

Check whether file id in process before starting the process of copy. You can call the following function until you get the False value.

1st Method, copied directly from this answer:

private bool IsFileLocked(FileInfo file)
{
    FileStream stream = null;

    try
    {
        stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
    }
    catch (IOException)
    {
        //the file is unavailable because it is:
        //still being written to
        //or being processed by another thread
        //or does not exist (has already been processed)
        return true;
    }
    finally
    {
        if (stream != null)
            stream.Close();
    }

    //file is not locked
    return false;
}

2nd Method:

const int ERROR_SHARING_VIOLATION = 32;
const int ERROR_LOCK_VIOLATION = 33;
private bool IsFileLocked(string file)
{
    //check that problem is not in destination file
    if (File.Exists(file) == true)
    {
        FileStream stream = null;
        try
        {
            stream = File.Open(file, FileMode.Open, FileAccess.ReadWrite, FileShare.None);
        }
        catch (Exception ex2)
        {
            //_log.WriteLog(ex2, "Error in checking whether file is locked " + file);
            int errorCode = Marshal.GetHRForException(ex2) & ((1 << 16) - 1);
            if ((ex2 is IOException) && (errorCode == ERROR_SHARING_VIOLATION || errorCode == ERROR_LOCK_VIOLATION))
            {
                return true;
            }
        }
        finally
        {
            if (stream != null)
                stream.Close();
        }
    }
    return false;
}

UPDATE
From v0.20, melt is a first order function, you can now use

df.melt(id_vars=["location", "name"], 
        var_name="Date", 
        value_name="Value")

  location    name        Date  Value
0        A  "test"    Jan-2010     12
1        B   "foo"    Jan-2010     18
2        A  "test"    Feb-2010     20
3        B   "foo"    Feb-2010     20
4        A  "test"  March-2010     30
5        B   "foo"  March-2010     25

OLD(ER) VERSIONS: <0.20

You can use pd.melt to get most of the way there, and then sort:

>>> df
  location  name  Jan-2010  Feb-2010  March-2010
0        A  test        12        20          30
1        B   foo        18        20          25
>>> df2 = pd.melt(df, id_vars=["location", "name"], 
                  var_name="Date", value_name="Value")
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
1        B   foo    Jan-2010     18
2        A  test    Feb-2010     20
3        B   foo    Feb-2010     20
4        A  test  March-2010     30
5        B   foo  March-2010     25
>>> df2 = df2.sort(["location", "name"])
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
2        A  test    Feb-2010     20
4        A  test  March-2010     30
1        B   foo    Jan-2010     18
3        B   foo    Feb-2010     20
5        B   foo  March-2010     25

(Might want to throw in a .reset_index(drop=True), just to keep the output clean.)

Note: pd.DataFrame.sort has been deprecated in favour of pd.DataFrame.sort_values.

This works for me.

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new 

StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = new JavaScriptSerializer().Serialize(new
                {
                    Username = "myusername",
                    Password = "password"
                });

    streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    var result = streamReader.ReadToEnd();
}

It's two steps but I like to do it this way:

First create a file with a particular date/time. In this case, the file is 2008-10-01 at midnight

touch -t 0810010000 /tmp/t

Now we can find all files that are newer or older than the above file (going by file modified date. You can also use -anewer for accessed and -cnewer file status changed).

find / -newer /tmp/t
find / -not -newer /tmp/t

You could also look at files between certain dates by creating two files with touch

touch -t 0810010000 /tmp/t1
touch -t 0810011000 /tmp/t2

This will find files between the two dates & times

find / -newer /tmp/t1 -and -not -newer /tmp/t2

This work for me:

sudo ln -fs "/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code" /usr/local/bin/

This function should do the trick if you want to specify a particular sheet. I took the solution from user6432984 and modified it to not throw any errors. I am using Excel 2016 so it may not work for older versions:

Function findLastRow(ByVal inputSheet As Worksheet) As Integer
    findLastRow = inputSheet.cellS(inputSheet.Rows.Count, 1).End(xlUp).Row
End Function

This is the code to run if you are already working in the sheet you want to find the last row of:

Dim lastRow as Integer
lastRow = cellS(Rows.Count, 1).End(xlUp).Row

You have to replace string line

QString line = in.readLine();

into while:

QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
    QMessageBox::information(0, "error", file.errorString());
}

QTextStream in(&file);

while(!in.atEnd()) {
    QString line = in.readLine();    
    QStringList fields = line.split(",");    
    model->appendRow(fields);    
}

file.close();

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

There is a typo error :

$('#activelist :checkbox')...

Should be :

$('#inactivelist:checkbox')...

From your config file, it seems like you're only excluding node_modules from being parsed with babel-loader, but not from being bundled.

In order to exclude node_modules and native node libraries from bundling, you need to:

1. Add target: 'node' to your webpack.config.js. This will exclude native node modules (path, fs, etc.) from being bundled.
2. Use webpack-node-externals in order to exclude other node_modules.

So your result config file should look like:

var nodeExternals = require('webpack-node-externals');
...
module.exports = {
    ...
    target: 'node', // in order to ignore built-in modules like path, fs, etc. 
    externals: [nodeExternals()], // in order to ignore all modules in node_modules folder 
    ...
};

I use this query here to get all relevant info (relevant for me, at least :-)) from SQL Server:

SELECT  
    SERVERPROPERTY('productversion') as 'Product Version', 
    SERVERPROPERTY('productlevel') as 'Product Level',  
    SERVERPROPERTY('edition') as 'Product Edition',
    SERVERPROPERTY('buildclrversion') as 'CLR Version',
    SERVERPROPERTY('collation') as 'Default Collation',
    SERVERPROPERTY('instancename') as 'Instance',
    SERVERPROPERTY('lcid') as 'LCID',
    SERVERPROPERTY('servername') as 'Server Name'

That gives you an output something like this:

Product Version   Product Level   Product Edition             CLR Version   
10.0.2531.0       SP1             Developer Edition (64-bit)    v2.0.50727  

Default Collation     Instance   LCID   Server Name 
Latin1_General_CI_AS     NULL    1033   *********       

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

To produce a border inset within an element the only solution I've found (and I've tried all the suggestions in this thread to no avail) is to use a pseudo-element such as :before

E.g.

.has-inset-border:before {
  content: "foo"; /* you need something or it will be invisible at least on Chrome */
  color: transparent;
  position: absolute;
  left: 10px;
  right: 10px;
  top: 10px;
  bottom: 10px;
  border: 4px dashed red;
}

The box-sizing property won't work, as the border always ends up outside everything.

The box-shadow options has the dual disadvantages of not really working and not being supported as widely (and costing more CPU cycles to render, if you care).

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

After installing it by mysqld --install. Try this mysqld --initialize. We got the same problem but it's now working.

I have found a way if you know startIndex and endIndex of the elements one need to remove from ArrayList

Let al be the original ArrayList and startIndex,endIndex be start and end index to be removed from the array respectively:

al.subList(startIndex, endIndex + 1).clear();

Example to download with wget on server a big file link that can be obtained in your browser.

In example using Google Chrome.

Login where you need, and press download. Go to download and copy your link.

Then open DevTools on a page where you where login, go to Console and get your cookies, by entering document.cookie

Now, go to server and download your file: wget --header "Cookie: <YOUR_COOKIE_OUTPUT_FROM_CONSOLE>" <YOUR_DOWNLOAD_LINK>

<?php echo substr($string, 0, strlen($string) - 3); ?>

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Try this.

<Directory "/home/userx/Downloads">
  Options +Indexes
  AllowOverride all
  Order allow,deny 
  Allow from all 
  Require all granted
</Directory>

If that doesn't work, you probably have 'deny indexes' somewhere that's overriding your config.

@JustGoscha's answer is spot on, but that's a lot to type when I want access, so I added this to the bottom of my app.js. Then all I have to type is x = getSrv('$http') to get the http service.

// @if DEBUG
function getSrv(name, element) {
    element = element || '*[ng-app]';
    return angular.element(element).injector().get(name);
}
// @endif

It adds it to the global scope but only in debug mode. I put it inside the @if DEBUG so that I don't end up with it in the production code. I use this method to remove debug code from prouduction builds.

1. Remove Containers:

$ docker rm $(docker ps -aq)

2. Remove Images:

$ docker rmi $(docker images -q)

Instead of perform steps 1 and 2 you can do:

docker system prune

This command will remove:

• All stopped containers
• All volumes not used by at least one container
• All networks not used by at least one container
• All dangling images

The most probable cause is that the content displaying over the popover has a higher z-index. Without the precise code/style, I can offer two options :

You should try pinpointing the exact elements with a web inspector (usually F12 on your favorite browser) and check their actual z-index.

If you find this value, you can set it lower than the popover which is z-index: 1010; by default

Or the other approach, not as good, would be to increase the z-index of the popover. You can do that either with the @zindexPopover in the Less files or directly by overriding

.popover {
    z-index: 1010; /* A value higher than 1010 that solves the problem */
}

If you can't find a solution, you should try reproducing the bug in something like this jsfiddle - you will probably resolve the problem while trying to get the bug.

Use path.join(__dirname, '/start.html');

var fs = require('fs'),
    path = require('path'),    
    filePath = path.join(__dirname, 'start.html');

fs.readFile(filePath, {encoding: 'utf-8'}, function(err,data){
    if (!err) {
        console.log('received data: ' + data);
        response.writeHead(200, {'Content-Type': 'text/html'});
        response.write(data);
        response.end();
    } else {
        console.log(err);
    }
});

Thanks to dc5.

Just use this:

svn  copy  http://svn.example.com/project/trunk  
           http://svn.example.com/project/branches/release-1
           -m  "branch for release 1.0"

(all on one line, of course.) You should always make a branch of the entire trunk folder and contents. It is of course possible to branch sub-parts of the trunk, but this will almost never be a good practice. You want the branch to behave exactly like the trunk does now, and for that to happen you have to branch the entire trunk.

See a better summary of SVN usage at my blog: SVN Essentials, and SVN Essentials 2

SELECT s.id, s.name, LENGTH(s.name) len, ASCII(s.name) ASCCCI FROM table_name s ORDER BY ASCCCI,len,NAME ASC;

If the string is at the beginning of the name, you can do this

$ compgen -f .bash
.bashrc
.bash_profile
.bash_prompt

Users who can Install MySQL Workbench on MySQL Server Machine

If you use or have MySQL Workbench on the MySQL Server PC you can do this with just a few clicks. Recommend only for development environment.

1. Connect to MySQL Server

2. Find this option Users and Privileges from Navigator and click on it.

3. Select root user and change value for Limit to Hosts Matching to %.

4. The click Apply at the bottom.

This should enable root user to access MySQL Server from remote machine.

double click on your form to create form_load event.Then inside that event write command.connection = "your connection name";

There is no standard way to delay a call to a function other than to use a timer and events.

This sounds like the GUI anti pattern of delaying a call to a method so that you can be sure the form has finished laying out. Not a good idea.

It can be added by using:

$psql -d databaseName -c "CREATE EXTENSION dblink"

In IMPALA, not having order in the GROUP_CONCAT can be problematic, over at Coders'Co. we have some sort of a workaround for that (we need it for Rax/Impala). If you need the GROUP_CONCAT result with an ORDER BY clause in IMPALA, take a look at this blog post: http://raxdb.com/blog/sorting-by-regex/

If order is important,

seen = set()
result = []
for c in foo:
    if c not in seen:
        result.append(c)
        seen.add(c)
result = ''.join(result)

Or to do it without sets:

result = []
for c in foo:
    if c not in result:
        result.append(c)
result = ''.join(result)

The only thing I would add to these amazing answers is to emphasize on saving your files in utf8 encoding, i have noticed that browsers accept this property over setting utf8 as your code encoding. Any decent text editor will show you this, for example Notepad++ has a menu option for file enconding, it shows you the current encoding and enables you to change it. For all my php files I use utf8 without BOM.

Sometime ago i had someone ask me to add utf8 support for a php/mysql application designed by someone else, i noticed that all files were encoded in ANSI, so I had to use ICONV to convert all files, change the database tables to use the utf8 charset and utf8_general_ci collate, add 'SET NAMES utf8' to the database abstraction layer after the connection (if using 5.3.6 or earlier otherwise you have to use charset=utf8 in the connection string) and change string functions to use the php multibyte string functions equivalent.

Redirecting Web Sites in IIS 6.0 (IIS 6.0)

When a browser requests a page or program on your Web site, the Web server locates the page identified by the URL and returns it to the browser. When you move a page on your Web site, you can't always correct all of the links that refer to the old URL of the page. To make sure that browsers can find the page at the new URL, you can instruct the Web server to redirect the browser to the new URL.

You can redirect requests for files in one directory to a different directory, to a different Web site, or to another file in a different directory. When the browser requests the file at the original URL, the Web server instructs the browser to request the page by using the new URL.

Important

You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".

Procedures

To redirect requests to another Web site or directory

1. In IIS Manager, expand the local computer, right-click the Web site or directory you want to redirect, and click Properties.

2. Click the Home Directory, Virtual Directory, or Directory tab.

3. Under The content for this source should come from, click A redirection to a URL.

4. In the Redirect to box, type the URL of the destination directory or Web site. For example, to redirect all requests for files in the Catalog directory to the NewCatalog directory, type /NewCatalog.
   

To redirect all requests to a single file

1. In IIS Manager, expand the local computer, right-click the Web site or directory you want to redirect, and click Properties.

2. Click the Home Directory, Virtual Directory, or Directory tab.

3. Under The content for this source should come from, click A redirection to a URL.

4. In the Redirect to box, type the URL of the destination file.

5. Select the The exact URL entered above check box to prevent the Web server from appending the original file name to the destination URL.

   You can use wildcards and redirect variables in the destination URL to precisely control how the original URL is translated into the destination URL.

   You can also use the redirect method to redirect all requests for files in a particular directory to a program. Generally, you should pass any parameters from the original URL to the program, which you can do by using redirect variables.
   

   To redirect requests to a program

   
   

6. In IIS Manager, expand the local computer, right-click the Web site or directory you want to redirect, and click Properties.

7. Click the Home Directory, Virtual Directory, or Directory tab.

8. Under The content for this source should come from, click A redirection to a URL.

   In the Redirect to box, type the URL of the program, including any redirect variables needed to pass parameters to the program. For example, to redirect all requests for scripts in a Scripts directory to a logging program that records the requested URL and any parameters passed with the URL, type /Scripts/Logger.exe?URL=$V+PARAMS=$P. $V and $P are redirect variables.

9. Select the The exact URL entered above check box to prevent the Web server from appending the original file name to the destination URL.

I got the same exact error with In case it helps others .. documenting what worked for me useful for very latest (Jan 14, 2017) latest everything. Tried all the Invalidate, build clean, even deleting .gradle/, tweaking the support libs etc.. on multiple stack overflow answers.

I found that upgrading the settings.gradle gradle version fixed it (it was 2.1.3) something in gradle toolchain seems to classpath 'com.android.tools.build:gradle:2.2.3'

Above Spring 4, there is no need to configure MappingJacksonHttpMessageConverter if you only intend to configure ObjectMapper.

(configure MappingJacksonHttpMessageConverter will cause you to lose other MessageConverter)

You just need to do:

public class MyObjectMapper extends ObjectMapper {

    private static final long serialVersionUID = 4219938065516862637L;

    public MyObjectMapper() {
        super();
        enable(SerializationFeature.INDENT_OUTPUT);
    }       
}

And in your Spring configuration, create this bean:

@Bean 
public MyObjectMapper myObjectMapper() {        
    return new MyObjectMapper();
}

you could make them all #'s.

You would then need to add return false; to the end of any function that is called onclick of the anchor to not have the page jump up to the top.

Answer from vpiTriumph lays out the details nicely.
Here's a small handy variation for when there are unique element ids for the data set you want to access:

$('.news-article').click(function(event){    
    var id = event.target.id;
    console.log('id = ' + id); 
});

    <item name="editTextColor">@color/white</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:textColorHint">@color/gray</item>
    <item name="android:textColorPrimary">@color/gray</item>
    <item name="colorControlNormal">@color/gray</item>

This is a way of backing into the indexes. You can use SHOWCONTIG to assess fragmentation. It will list all of the indexes for the database or table, along with statistics. I would caution that on a large database, it can be long-running. For me, one of the benefits of this approach is that you don't have to be an admin to use it.

--Show fragmentation info on all indexes in a database

SET NOCOUNT ON
USE pubs
DBCC SHOWCONTIG WITH ALL_INDEXES
GO

...turn NOCOUNT back OFF when done

--Show fragmentation info on all indexes on a table

SET NOCOUNT ON
USE pubs
DBCC SHOWCONTIG (authors) WITH ALL_INDEXES
GO

--Show fragmentation information on a specific index

SET NOCOUNT ON
USE pubs
DBCC SHOWCONTIG (authors,aunmind)
GO

Answer 1:

• Downloading bootstrap through npm (or bower) permits you to gain some latency time. Instead of getting a remote resource, you get a local one, it's quicker, except if you use a cdn (check below answer)

• "npm" was originally to get Node Module, but with the essort of the Javascript language (and the advent of browserify), it has a bit grown up. In fact, you can even download AngularJS on npm, that is not a server side framework. Browserify permits you to use AMD/RequireJS/CommonJS on client side so node modules can be used on client side.

Answer 2:

If you npm install bootstrap (if you dont use a particular grunt or gulp file to move to a dist folder), your bootstrap will be located in "./node_modules/bootstrap/bootstrap.min.css" if I m not wrong.

Looks like "+x" causes problems:

root@raspi1:~# cat > /tmp/btest
#!/bin/bash

jobname="job_201312161447_0003"
jobname_pre=${jobname:0:16}
jobname_post=${jobname:17}
root@raspi1:~# chmod +x /tmp/btest
root@raspi1:~# /tmp/btest
root@raspi1:~# sh -x /tmp/btest
+ jobname=job_201312161447_0003
/tmp/btest: 4: /tmp/btest: Bad substitution

Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :

var elements = document.getElementById('parentContainer').children;

Option 2: Likely slowest :

var elements = document.getElementById('parentContainer').getElementsByTagName('*');

Option 3: Requires change to code (wrap a form instead of a div around it) :

// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;

var matches = [];

for (var i = 0; i < elements.length; i++)
    if (elements[i].value.indexOf('q17_') == 0)
        matches.push(elements[i]);

you should set document title in the life cycle of 'componentWillMount':

componentWillMount() {
    document.title = 'your title name'
  },

My search for a similar solution for Visual Studio 2015/Xamarin lead me to this thread. While setting the EditText.InputType to Android.Text.InputTypes.TextVariationVisiblePassword properly hid the password during user entry, it did not 'hide' the password if it was visible before the EditText Layout was rendered (before the user submitted their password entry). In order to hide a visible password after the user submits their password and the EditText Layout is rendered, I used EditText.TransformationMethod = PasswordTransformationMethod.Instance as suggested by LuxuryMode.

I came up with a more direct solution that is admittedly ugly but fixes the real problem. It goes a bit like this:

resp = requests.get(some_url, stream=True)
resp.raw._fp.fp._sock.settimeout(read_timeout)
# This will load the entire response even though stream is set
content = resp.content

You can read the full explanation here

You need to inject mock inside the class you're testing. At the moment you're interacting with the real object, not with the mock one. You can fix the code in a following way:

void testAbc(){
     myClass.myObj = myInteface;
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}

although it would be a wiser choice to extract all initialization code into @Before

@Before
void setUp(){
     myClass = new myClass();
     myClass.myObj = myInteface;
}

@Test
void testAbc(){
     myClass.abc();
     verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
}

In this case the variable titled var in the method Change is assigned a reference to self.variable, and you immediately assign a string to var. It's no longer pointing to self.variable. The following code snippet shows what would happen if you modify the data structure pointed to by var and self.variable, in this case a list:

>>> class PassByReference:
...     def __init__(self):
...         self.variable = ['Original']
...         self.change(self.variable)
...         print self.variable
...         
...     def change(self, var):
...         var.append('Changed')
... 
>>> q = PassByReference()
['Original', 'Changed']
>>> 

I'm sure someone else could clarify this further.

Another usage of colon in JavaScript is to rename a variable, that is:

const person = { 
    nickNameThatIUseOnStackOverflow: "schlingel",
    age: 30,
    firstName: "John"
};
let { nickNameThatIUseOnStackOverflow: nick } = person; // I take nickNameThatIUseOnStackOverflow but want to refer it as "nick" from now on.
nick = "schling";

This is useful if you use a third party library that returns values having awkward / long variable names that you want to rename in your code.

Here is my approach that you may try:

import numpy as np
import matplotlib.pyplot as plt

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = np.random.randint(10, size=(h,w))
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The resulting image:

Edit 1

Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-

1. access to individual axes of subplots
2. possibility to plot more features on selected axes/subplot

New code:

import numpy as np
import matplotlib.pyplot as plt

w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5

# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# ax enables access to manipulate each of subplots
ax = []

for i in range(columns*rows):
    img = np.random.randint(10, size=(h,w))
    # create subplot and append to ax
    ax.append( fig.add_subplot(rows, columns, i+1) )
    ax[-1].set_title("ax:"+str(i))  # set title
    plt.imshow(img, alpha=0.25)

# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)

plt.show()  # finally, render the plot

The resulting plot:

Edit 2

In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index], which is more suitable for manipulation of array of many sub-plots.

import matplotlib.pyplot as plt
import numpy as np

# settings
h, w = 10, 10        # for raster image
nrows, ncols = 5, 4  # array of sub-plots
figsize = [6, 8]     # figure size, inches

# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)

# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
    # i runs from 0 to (nrows*ncols-1)
    # axi is equivalent with ax[rowid][colid]
    img = np.random.randint(10, size=(h,w))
    axi.imshow(img, alpha=0.25)
    # get indices of row/column
    rowid = i // ncols
    colid = i % ncols
    # write row/col indices as axes' title for identification
    axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))

# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)

plt.tight_layout(True)
plt.show()

The resulting plot:

To change tab settings, click the text area right to the Ln/Col text in the status bar on the bottom right of vscode window.

Add one more slash after file:// in the value of xsi:schemaLocation. (You have two; you need three. Think protocol://host/path where protocol is 'file' and host is empty here, yielding three slashes in a row.) You can also eliminate the double slashes along the path. I believe that the double slashes help with file systems that allow spaces in file and directory names, but you wisely avoided that complication in your path naming.

xsi:schemaLocation="http://www.w3schools.com file:///C:/environment/workspace/maven-ws/ProjextXmlSchema/email.xsd"

Still not working? I suggest that you carefully copy the full file specification for the XSD into the address bar of Chrome or Firefox:

file:///C:/environment/workspace/maven-ws/ProjextXmlSchema/email.xsd

If the XSD does not display in the browser, delete all but the last component of the path (email.xsd) and see if you can't display the parent directory. Continue in this manner, walking up the directory structure until you discover where the path diverges from the reality of your local filesystem.

If the XSD does displayed in the browser, state what XML processor you're using, and be prepared to hear that it's broken or that you must work around some limitation. I can tell you that the above fix will work with my Xerces-J-based validator.

Temporary workaround: unicode(urllib2.urlopen(url).read(), 'utf8') - this should work if what is returned is UTF-8.

urlopen().read() return bytes and you have to decode them to unicode strings. Also it would be helpful to check the patch from http://bugs.python.org/issue4733

Here's a way to get the local timezone using only the standard library, (only works in a *nix environment):

>>> '/'.join(os.path.realpath('/etc/localtime').split('/')[-2:])
'Australia/Sydney'

You can use this to create a pytz timezone:

>>> import pytz
>>> my_tz_name = '/'.join(os.path.realpath('/etc/localtime').split('/')[-2:])
>>> my_tz = pytz.timezone(my_tz_name)
>>> my_tz
<DstTzInfo 'Australia/Sydney' LMT+10:05:00 STD>

...which you can then apply to a datetime:

>>> import datetime
>>> now = datetime.datetime.now()
>>> now
datetime.datetime(2014, 9, 3, 9, 23, 24, 139059)

>>> now.replace(tzinfo=my_tz)
>>> now
datetime.datetime(2014, 9, 3, 9, 23, 24, 139059, tzinfo=<DstTzInfo 'Australia/Sydney' LMT+10:05:00 STD>)

orphanRemoval has nothing to do with ON DELETE CASCADE.

orphanRemoval is an entirely ORM-specific thing. It marks "child" entity to be removed when it's no longer referenced from the "parent" entity, e.g. when you remove the child entity from the corresponding collection of the parent entity.

ON DELETE CASCADE is a database-specific thing, it deletes the "child" row in the database when the "parent" row is deleted.

As of now Google has changed their AJAX crawling proposal.

Times have changed. Today, as long as you're not blocking Googlebot from crawling your JavaScript or CSS files, we are generally able to render and understand your web pages like modern browsers.

tl;dr: [Google] are no longer recommending the AJAX crawling proposal [Google] made back in 2009.

Building on Henks answer I have created some test methods with his answer and some added, more optimized, methods. I found the results differ based on the size of the input string. Therefore, I have tested with two result sets. In the fastest method, the linked source has a even faster way. But, since it is characterized as unsafe I have left this out.

Long input string results:

1. InPlaceCharArray: 2021 ms (Sunsetquest's answer) - (Original source)
2. String split then join: 4277ms (Kernowcode's answer)
3. String reader: 6082 ms
4. LINQ using native char.IsWhitespace: 7357 ms
5. LINQ: 7746 ms (Henk's answer)
6. ForLoop: 32320 ms
7. RegexCompiled: 37157 ms
8. Regex: 42940 ms

Short input string results:

1. InPlaceCharArray: 108 ms (Sunsetquest's answer) - (Original source)
2. String split then join: 294 ms (Kernowcode's answer)
3. String reader: 327 ms
4. ForLoop: 343 ms
5. LINQ using native char.IsWhitespace: 624 ms
6. LINQ: 645ms (Henk's answer)
7. RegexCompiled: 1671 ms
8. Regex: 2599 ms

Edit: Tested a nice one liner from Kernowcode.

ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable("COLOR")); 

it worked for me here

add app:elevation="0dp" in AppBarLayout for hiding shadow in appbar

This will work:

if 'A' in df:

But for clarity, I'd probably write it as:

if 'A' in df.columns:

SUM is used to sum the value in a column for multiple rows. You can just add your columns together:

select tblExportVertexCompliance.TotalDaysOnIncivek + tblExportVertexCompliance.IncivekDaysOtherSource AS [Total Days on Incivek]

This is an old question, but I thought I'd put in my C# 6 answer. I often have to set up test data that is easily entered in-code as a list of tuples. With a couple of extension functions, it is possible to have this nice, compact format, without repeating the names on each entry.

var people= new List<Tuple<int, int, string>>() {
    {1, 11, "Adam"},
    {2, 22, "Bill"},
    {3, 33, "Carol"}
}.Select(t => new { Id = t.Item1, Age = t.Item2, Name = t.Item3 });

This gives an IEnumerable - if you want a list that you can add to then just add ToList().

The magic comes from custom extension Add methods for tuples, as described at https://stackoverflow.com/a/27455822/4536527.

public static class TupleListExtensions    {
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)       {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3) {
        list.Add(Tuple.Create(item1, item2, item3));
    }

// and so on...

}

The only thing I don't like is that the types are separated from the names, but if you really don't want to make a new class then this approach will still let you have readable data.

There is an error in the example.... if you use it as written, the following error occurs:

< type 'exceptions.Exception' >: 'dict' object has no attribute 'render_context'

You will need to add the following import:

from django.template import Context

and change the dictionary to be:

d = Context({ 'username': username })

See http://docs.djangoproject.com/en/1.2/ref/templates/api/#rendering-a-context

I saw this when I was trying to access the members.

My struct was this:

struct test { 
    int a;
    int b;
};
    
struct test testvar;

Normally we access structure members as

testvar.a;
testvar.b;

I mistook testvar to be a pointer and did this.

testvar->a;

That's when I saw this error.

request for member ‘a’ in something not a structure or union

@owlstead, regarding your request for "a cryptographically secure variant of one of the given answers," please see RNCryptor. It was designed to do exactly what you're requesting (and was built in response to the problems with the code listed here).

RNCryptor uses PBKDF2 with salt, provides a random IV, and attaches HMAC (also generated from PBKDF2 with its own salt. It support synchronous and asynchronous operation.

You will want to move the loop for the files outside of the loop for the folders. In addition you will need to pass the data structure holding the collection of files to each call of the method. That way all files go into a single list.

public static List<string> DirSearch(string sDir, List<string> files)
{
  foreach (string f in Directory.GetFiles(sDir, "*.xml"))
  {
    string extension = Path.GetExtension(f);
    if (extension != null && (extension.Equals(".xml")))
    {
      files.Add(f);
    }
  }
  foreach (string d in Directory.GetDirectories(sDir))
  {
    DirSearch(d, files);
  }
  return files;
}

Then call it like this.

List<string> files = DirSearch("c:\foo", new List<string>());

Update:

Well unbeknownst to me, until I read the other answer anyway, there is already a builtin mechanism for doing this. I will leave my answer in case you are interested in seeing how your code needs to be modified to make it work.

According to user m9dhatter on LinuxQuestions.org:

"make" uses the time stamp of the file to determine if the file it is trying to compile is old or new. if your clock is bonked, it may have problems compiling.

if you try to modify files at another machine with a clock time ahead by a few minutes and transfer them to your machine and then try to compile it may cough up a warning that says the file was modified from the future. clock may be skewed or something to that effect ( cant really remember ). you could just ls to the offending file and do this:

#touch <filename of offending file>

_{MuSTaNG's answer says it all, but I am still adding it to make it a little more elaborate, with links and all.}

The conventional operators

• greater than (>),
• less than (<),
• equality (==),
• and more

are available for DateTime since .NET Framework 1.1. Also, addition and subtraction of DateTime objects are also possible using conventional operators + and -.

One example from MSDN:

System.DateTime april19 = new DateTime(2001, 4, 19);
System.DateTime otherDate = new DateTime(1991, 6, 5);

// areEqual gets false.
bool areEqual = april19 == otherDate;

otherDate = new DateTime(2001, 4, 19);
// areEqual gets true.
areEqual = april19 == otherDate;

Other operators can be used likewise.

Here is the list all operators available for DateTime.

It is essentially a security measure. If your app is compromised, the attacker will only have access to the short-lived access token and no way to generate a new one.

Refresh tokens also expire but they are supposed to live much longer than the access token.

As android:editable="false" deprecated In xml

Use android:enabled="false" it's simple. Why use more code?

If you want in java class you can also use this programmatically

 editText.setEnabled(false);

1. Create a table with Identity column + other columns;
2. Create a view over it and expose only the columns you will bulk insert;
3. BCP in the view

You are consuming a line at, which is discarded

while((str=input.readLine())!=null && str.length()!=0)

and reading a bigint at

BigInteger n = new BigInteger(input.readLine());

so try getting the bigint from string which is read as

BigInteger n = new BigInteger(str);

   Constructor used: BigInteger(String val)

Aslo change while((str=input.readLine())!=null && str.length()!=0) to

while((str=input.readLine())!=null)

see related post string to bigint

readLine()
Returns:
    A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached 

see javadocs

Most likely, cron is running in a very sparse environment. Check the environment variables cron is using by appending a dummy job which dumps env to a file like this:

* * * * * env > env_dump.txt

Compare that with the output of env in a normal shell session.

You can prepend your own environment variables to the local crontab by defining them at the top of your crontab.

Here's a quick fix to prepend $PATH to the current crontab:

# echo PATH=$PATH > tmp.cron
# echo >> tmp.cron
# crontab -l >> tmp.cron
# crontab tmp.cron

The resulting crontab will look similar to chrissygormley's answer, with PATH defined before the crontab rules.

If you want to know this, it exists an open source library called aFileDialog that it is an small and easy to use which provides a file picker.

The difference with another file chooser's libraries for Android is that aFileDialog gives you the option to open the file chooser as a Dialog and as an Activity.

It also lets you to select folders, create files, filter files using regular expressions and show confirmation dialogs.

If you want a pure CSS solution, this trick works very well - use the transform object. This also works with images when they're cached or not:

CSS:

.main_container{
    position: relative;
    width: 500px;
    height: 300px;
    background-color: #cccccc;
}

.center_horizontally{
  position: absolute;
  width: 100px;
  height: 100px;
  background-color: green;
  left: 50%;
  top: 0;
  transform: translate(-50%,0);
}

.center_vertically{
  position: absolute;
  top: 50%;
  left: 0;
  width: 100px;
  height: 100px;
  background-color: blue;
  transform: translate(0,-50%);
}

.center{
  position: absolute;
  top: 50%;
  left: 50%;
  width: 100px;
  height: 100px;
  background-color: red;
  transform: translate(-50%,-50%);
}

HTML:

<div class="main_container">
  <div class="center_horizontally"></div>
  <div class="center_vertically"></div>
  <div class="center"></div>
  </div>
</div

1.THE USE OF {}:

It initialize the array with the values { }

2.The difference between String array=new String[]; and String array=new String[]{};

String array=new String[]; and String array=new String[]{}; both are invalid statement in java.

It will gives you an error that you are trying to assign String array to String datatype. More specifically error is like this Type mismatch: cannot convert from String[] to String

3.String array=new String[10]{}; got error why?

Wrong because you are defining an array of length 10 ([10]), then defining an array of length String[10]{} 0

Take a Look.

$(document).ready(function () {     
        $('#datatable').DataTable({
            columns: [
                { 'data': 'ID' },
                { 'data': 'AuthorName' },
                { 'data': 'TotalBook' },
                { 'data': 'DateofBirth' },
                { 'data': 'OccupationEN' },   
                { 'data': null, title: 'Action', wrap: true, "render": function (item) { return '<div class="btn-group"> <button type="button" onclick="set_value(' + item.ID + ')" value="0" class="btn btn-warning" data-toggle="modal" data-target="#myModal">View</button></div>' } },
            ],            
            bServerSide: true,
            sAjaxSource: 'EmployeeDataHandler.ashx'

The RIGHT and WRONG way to set Python 3 as default on a Mac

In this article author discuss three ways of setting default python:

1. What NOT to do.
2. What we COULD do (but also shouldn't).
3. What we SHOULD do!

All these ways are working. You decide which is better.

The only way I have 100% consistently been able to avoid this flex-direction column bug is to use a min-width media query to assign a max-width to the child element on desktop sized screens.

.parent {
    display: flex;
    flex-direction: column;
}

//a media query targeting desktop sort of sized screens
@media screen and (min-width: 980px) {
    .child {
        display: block;
        max-width: 500px;//maximimum width of the element on a desktop sized screen
    }
}

You will need to set naturally inline child elements (eg. <span> or <a>) to something other than inline (mainly display:block or display:inline-block) for the fix to work.

Starting with parameter:

setup.exe /A

asks for saving included files (including MSI).

This may depend on the software which created the setup.exe.

I found the approach given by cimmanon and Kurt Mueller almost worked, but that I needed a parent reference (i.e., I need to add the '&' prefix to each vendor prefix); like this:

@mixin placeholder {
    &::-webkit-input-placeholder {@content}
    &:-moz-placeholder           {@content}
    &::-moz-placeholder          {@content}
    &:-ms-input-placeholder      {@content}  
}

I use the mixin like this:

input {
    @include placeholder {
        font-family: $base-font-family;
        color: red;
    }
}

With the parent reference in place, then correct css gets generated, e.g.:

input::-webkit-input-placeholder {
    font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Liberation Serif", Georgia, serif;
    color: red;
}

Without the parent reference (&), then a space is inserted before the vendor prefix and the CSS processor ignores the declaration; that looks like this:

input::-webkit-input-placeholder {
    font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Liberation Serif", Georgia, serif;
    color: red;
}

First off, the CASE statement must be part of the expression, not the expression itself.

In other words, you can have:

WHERE co.DTEntered = CASE 
                          WHEN LEN('blah') = 0 
                               THEN co.DTEntered 
                          ELSE '2011-01-01' 
                     END 

But it won't work the way you have written them eg:

WHERE 
    CASE LEN('TestPerson')
        WHEN 0 THEN co.personentered  = co.personentered
   ELSE co.personentered LIKE '%TestPerson'
    END 

You may have better luck using combined OR statements like this:

WHERE (
        (LEN('TestPerson') = 0 
             AND co.personentered = co.personentered
        ) 
        OR 
        (LEN('TestPerson') <> 0 
             AND co.personentered LIKE '%TestPerson')
      )

Although, either way I'm not sure how great of a query plan you'll get. These types of shenanigans in a WHERE clause will often prevent the query optimizer from utilizing indexes.

When I run maven test, java.lang.OutOfMemoryError happens. I google it for solutions and have tried to export MAVEN_OPTS=-Xmx1024m, but it did not work.

Setting the Xmx options using MAVEN_OPTS does work, it does configure the JVM used to start Maven. That being said, the maven-surefire-plugin forks a new JVM by default, and your MAVEN_OPTS are thus not passed.

To configure the sizing of the JVM used by the maven-surefire-plugin, you would either have to:

• change the forkMode to never (which is be a not so good idea because Maven won't be isolated from the test) ~or~
• use the argLine parameter (the right way):

In the later case, something like this:

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

But I have to say that I tend to agree with Stephen here, there is very likely something wrong with one of your test and I'm not sure that giving more memory is the right solution to "solve" (hide?) your problem.

Another way:

var := coalesce (var, 5);

COALESCE is the ANSI equivalent (more or less) of Oracle's NVL function.

• element = np.nan
• ser1 = ser1.append(pd.Series(element))

If you are using NUnit, take a look at this post. Basically you'll need to have your app.config in the same directory as your .nunit file.

You should also look into commands.getstatusoutput

This returns a tuple of length 2.. The first is the return integer ( 0 - when the commands is successful ) second is the whole output as will be shown in the terminal.

For ls

    import commands
    s=commands.getstatusoutput('ls')
    print s
    >> (0, 'file_1\nfile_2\nfile_3')
    s[1].split("\n")
    >> ['file_1', 'file_2', 'file_3']

Ok, the way I see it you have 3 options.

1: If you simply wish to check whether the number is an integer, and don't care about converting it, but simply wish to keep it as a string and don't care about potential overflows, checking whether it matches a regex for an integer would be ideal here.

2: You can use boost::lexical_cast and then catch a potential boost::bad_lexical_cast exception to see if the conversion failed. This would work well if you can use boost and if failing the conversion is an exceptional condition.

3: Roll your own function similar to lexical_cast that checks the conversion and returns true/false depending on whether it's successful or not. This would work in case 1 & 2 doesn't fit your requirements.

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="objectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(
        @RequestParam DataProcessingRequestDTO jsonPenguinRequestDTO)

Request Sent:

        },
        {
            "data": {
                "_": "",
                "header": ""

            "name": "",
            "searchable": false,
            "orderable": false,
            "search": {
                "value": "",
                "regex": false
            }
        }
    ],
    "order": [
        {
            "column": 0,
            "dir": "asc"
        }
    ],
    "start": 0,
    "length": 10,
    "search": {
        "value": "",
        "regex": false
    },
    "objectId": "30"
}

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

You can use a for..of loop to loop over an array of objects.

for (let item of items) {
    console.log(item); // Will display contents of the object inside the array
}

One of the best things about for..of loops is that they can iterate over more than just arrays. You can iterate over any type of iterable, including maps and objects. Make sure you use a transpiler or something like TypeScript if you need to support older browsers.

If you wanted to iterate over a map, the syntax is largely the same as the above, except it handles both the key and value.

for (const [key, value] of items) {
  console.log(value);
}

I use for..of loops for pretty much every kind of iteration I do in Javascript. Furthermore, one of the coolest things is they also work with async/await as well.

Looks it's one of the early asked question about Golang . And same time answers to never update . During these three to four years , too many new libraries and blog post has been out . Below are the few links what I felt useful .

Try the xlrd library.

[Edit] - from what I can see from your comment, something like the snippet below might do the trick. I'm assuming here that you're just searching one column for the word 'john', but you could add more or make this into a more generic function.

from xlrd import open_workbook

book = open_workbook('simple.xls',on_demand=True)
for name in book.sheet_names():
    if name.endswith('2'):
        sheet = book.sheet_by_name(name)

        # Attempt to find a matching row (search the first column for 'john')
        rowIndex = -1
        for cell in sheet.col(0): # 
            if 'john' in cell.value:
                break

        # If we found the row, print it
        if row != -1:
            cells = sheet.row(row)
            for cell in cells:
                print cell.value

        book.unload_sheet(name) 

You need to access the matches in order to get at the SDI number. Here is a function that will do it (assuming there is only 1 SDI number per cell).

For the regex, I used "sdi followed by a space and one or more numbers". You had "sdi followed by a space and zero or more numbers". You can simply change the + to * in my pattern to go back to what you had.

Function ExtractSDI(ByVal text As String) As String

Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = "(sdi \d+)"
RE.Global = True
RE.IgnoreCase = True
Set allMatches = RE.Execute(text)

If allMatches.count <> 0 Then
    result = allMatches.Item(0).submatches.Item(0)
End If

ExtractSDI = result

End Function

If a cell may have more than one SDI number you want to extract, here is my RegexExtract function. You can pass in a third paramter to seperate each match (like comma-seperate them), and you manually enter the pattern in the actual function call:

Ex) =RegexExtract(A1, "(sdi \d+)", ", ")

Here is:

Function RegexExtract(ByVal text As String, _
                      ByVal extract_what As String, _
                      Optional seperator As String = "") As String

Dim i As Long, j As Long
Dim result As String
Dim allMatches As Object
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")

RE.pattern = extract_what
RE.Global = True
Set allMatches = RE.Execute(text)

For i = 0 To allMatches.count - 1
    For j = 0 To allMatches.Item(i).submatches.count - 1
        result = result & seperator & allMatches.Item(i).submatches.Item(j)
    Next
Next

If Len(result) <> 0 Then
    result = Right(result, Len(result) - Len(seperator))
End If

RegexExtract = result

End Function

*Please note that I have taken "RE.IgnoreCase = True" out of my RegexExtract, but you could add it back in, or even add it as an optional 4th parameter if you like.

I simply restarted my Mac and my iPhone 6 and the problem was solved. I never had to change my deployment target.

Yes. There isn't any limit on a GET request.

I am able to send ~4000 characters as part of the query string using both the Chrome browser and curl command.

I am using Tomcat 8.x server which has returned the expected 200 OK response.

Here is the screenshot of a Google Chrome HTTP request (hiding the endpoint I tried due to security reasons):

RESPONSE

Just to reconcile the difference between sandeepmistry's answer and davidgyoung's answer:

02 01 1a 1a ff 4C 00

Is part of the advertising data format specification [1]

  02 # length of following AD structure
  01 # <<Flags>> AD Structure [2]
  1a # read as b00011010. 
     # In this case, LE General Discoverable,
     # and simultaneous BR/EDR but this may vary by device!

  1a # length of following AD structure
  FF # Manufacturer specific data [3]
4C00 # Apple Inc [4]
0215 # ?? some 2-byte header

Missing from the AD is a Service [5] definition. I think the iBeacon protocol itself has no relationship to the GATT and standard service discovery. If you download RedBearLab's iBeacon program, you'll see that they happen to use the GATT for configuring the advertisement parameters, but this seems to be specific to their implementation, and not part of the spec. The AirLocate program doesn't seem to use the GATT for configuration, for instance, according to LightBlue and or other similar programs I tried.

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

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

I modified the code because in my case I needed

        Friend Function FullOuterJoin(Of TA, TB, TResult)(ByVal a As IEnumerable(Of TA), ByVal b As IEnumerable(Of TB), ByVal joinPredicate As Func(Of TA, TB, Boolean), ByVal projection As Func(Of TA, TB, TResult), ByVal comparer As IEqualityComparer(Of TResult)) As IEnumerable(Of TResult)
            Dim joinL =

                From xb In b.Where(Function(x) joinPredicate(xa, x)).DefaultIfEmpty()
                Select projection(xa, xb)
            Dim joinR =

Yes, you need to use PropTypes.arrayOf instead of PropTypes.array in the code, you can do something like this:

import PropTypes from 'prop-types';

MyComponent.propTypes = {
  annotationRanges: PropTypes.arrayOf(
    PropTypes.shape({
      start: PropTypes.string.isRequired,
      end: PropTypes.number.isRequired
    }).isRequired
  ).isRequired
}

Also for more details about proptypes, visit Typechecking With PropTypes here

This is my AppTheme on an example app:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowIsTranslucent">true</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

As you can see, I have the default colors and then I added the android:windowIsTranslucent and set it to true.

As far as I know as an Android Developer, this is the only thing you need to set in order to hide the white screen on the start of the application.

This is the ASCII format.

Please consider that:

Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.

To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters table.

Digging to table you can find

Oct Dec Hex Name 012 10 0A Line Feed

In the html file you can use Dec and Hex representation of charters

The Dec is represented with 


The Hex is represented with &#x0A (or you can omit the leading zero &#xA)

There is a good converter at https://r12a.github.io/apps/conversion/ .

To understand the use of "SET SERVEROUTPUT ON" I will take an example

DECLARE
a number(10)  :=10;
BEGIN
dbms_output.put_line(a) ;
dbms_output.put_line('Hello World ! ')  ;
END ;

With an output : PL/SQl procedure successfully completed i.e without the expected output

And the main reason behind is that ,whatever we pass inside dbms_output.put_line(' ARGUMENT '/VALUES) i.e. ARGUMENT/VALUES , is internally stored inside a buffer in SGA(Shared Global Area ) memory area upto 2000 bytes .

*NOTE :***However one should note that this buffer is only created when we use **dbms_output package. And we need to set the environment variable only once for a session !!

And in order to fetch it from that buffer we need to set the environment variable for the session . It makes a lot of confusion to the beginners that we are setting the server output on ( because of its nomenclature ) , but unfortunately its nothing like that . Using SET SERVER OUTPUT ON are just telling the PL/SQL engine that

*Hey please print the ARGUMENT/VALUES that I will be passing inside dbms_output.put_line
and in turn PL/SQl run time engine prints the argument on the main console .

I think I am clear to you all . Wish you all the best . To know more about it with the architectural structure of Oracle Server Engine you can see my answer on Quora http://qr.ae/RojAn8

And to answer your question "One should use SET SERVER OUTPUT in the beginning of the session. "

You can use Localstorage

1- Add dependency to pubspec.yaml (Change the version based on the last)

dependencies:
  ...
  localstorage: ^3.0.0

2- Then run the following command

flutter packages get

3- import the localstorage :

import 'package:localstorage/localstorage.dart';

4- create an instance

class MainApp extends StatelessWidget {
  final LocalStorage storage = new LocalStorage('localstorage_app');
  ...
}

Add item to lcoalstorage :

void addItemsToLocalStorage() {
  storage.setItem('name', 'Abolfazl');
  storage.setItem('family', 'Roshanzamir');

  final info = json.encode({'name': 'Darush', 'family': 'Roshanzami'});
  storage.setItem('info', info);
}

Get an item from lcoalstorage:

void getitemFromLocalStorage() {
  final name = storage.getItem('name'); // Abolfazl
  final family = storage.getItem('family'); // Roshanzamir
  
  Map<String, dynamic> info = json.decode(storage.getItem('info'));
  final info_name=info['name'];
  final info_family=info['family'];
}

Delete an item from localstorage :

void removeItemFromLocalStorage() {
  storage.deleteItem('name');
  storage.deleteItem('family');
  storage.deleteItem('info');
}

When running the test use the -s option. All print statements in exampletest.py would get printed on the console when test is run.

py.test exampletest.py -s

Quick answer for single line span

Make the child (in this case a span) the same line-height as the parent <div>'s height

<div class="parent">
  <span class="child">Yes mom, I did my homework lol</span>
</div>

You should then add the CSS rules

.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }

Or you can target it with a child selector

.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }

Background on my own use of this

I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)

HTML

<div class="international">        
  <span class="intlFlag">
    {{flag}}        
  </span>

  <span class="intlCurrent">
    {{country}}
  </span>

  <span class="intlButton">
    <i class="fa fa-globe"></i>
  </span> 
</div>

CSS (option for multiple spans in a div)

.international {
  height: 42px;
}

.international > span {
  line-height: 42px;
}

In this case if I just had one span I could have added the CSS rule directly to that span.

CSS (option for one specific span)

.intlFlag { line-height: 42px; }

Here is how it displayed for me

Using ONLY css is impossbile. In fact, all form elements are impossible to customize to look in the same way on all browsers only with css. You can try niceforms though ;)

Map does not supports duplicate keys. you can use collection as value against same key.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value.

Documentation

you can use any kind of List or Set implementation according to your requirement.

If your values might be also duplicate you can go with ArrayList or LinkedList, in case values are unique you can use HashSet or TreeSet etc.

Also In google guava collection library Multimap is available, it is a collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values. You can visualize the contents of a multimap either as a map from keys to nonempty collections of values:

a ? 1, 2
b ? 3  

Example -

ListMultimap<String, String> multimap = ArrayListMultimap.create();
multimap.put("a", "1");
multimap.put("a", "2");
multimap.put("c", "3");

You can use nonzero function. it returns the nonzero indices of the given input.

Easy Way

>>> (e > 15).nonzero()

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

to see the indices more cleaner, use transpose method:

>>> numpy.transpose((e>15).nonzero())

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Not Bad Way

>>> numpy.nonzero(e > 15)

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

or the clean way:

>>> numpy.transpose(numpy.nonzero(e > 15))

[[1 6]
 [1 7]

I believe buffer length needs to be specified, as memory is finite and you may run out of it

Example:

InputStream in = new FileInputStream(strFileName);
    long length = fileFileName.length();

    if (length > Integer.MAX_VALUE) {
        throw new IOException("File is too large!");
    }

    byte[] bytes = new byte[(int) length];

    int offset = 0;
    int numRead = 0;

    while (offset < bytes.length && (numRead = in.read(bytes, offset, bytes.length - offset)) >= 0) {
        offset += numRead;
    }

    if (offset < bytes.length) {
        throw new IOException("Could not completely read file " + fileFileName.getName());
    }

    in.close();

Yet another idea to throw in to the mix... In my case, the component throwing the error was a template-less component with a custom render() function. I couldn't see why it wasn't working, until I realised that I hadn't put <script>...</script> tags around the code in the component (seemed unnecessary, since I had no template or style tags either). Not sure why this got past the compiler...?

Either way... make sure you use your <script> tags ;-)

If ajax request is not fired, please check the select2 class in the select element. Removing the select2 class will fix that issue.

in spring boot project we can write logging.level.root=WARN but here problem is, we have to restart again even we added devtools dependency, in property file if we are modified any value will not autodetectable, for this limitation i came to know the solution i,e we can add actuator in pom.xml and pass the logger level as below shown in postman client in url bar http://localhost:8080/loggers/ROOT or http://localhost:8080/loggers/com.mycompany and in the body you can pass the json format like below

{
  "configuredLevel": "WARN"
}

Use vertical-align:top; for the element you want at the top, as I have demonstrated on your jsfiddle.

Following code works..

datePickerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(0);
        }
    });

@Override
@Deprecated
protected Dialog onCreateDialog(int id) {
    return new DatePickerDialog(this, datePickerListener, year, month, day);
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        day = selectedDay;
        month = selectedMonth;
        year = selectedYear;
        datePickerButton.setText(selectedDay + " / " + (selectedMonth + 1) + " / "
                + selectedYear);
    }
};

I've seen a couple cases where this error occurs:

1. using the not equals operator != in a where clause with a list of multiple or values

such as:

where columnName !=('A'||'B')

This can be resolved by using

where columnName not in ('A','B')

2. missing a comparison operator in an if() function:

select if(col1,col1,col2);

in order to select the value in col1 if it exists and otherwise show the value in col2...this throws the error; it can be resolved by using:

select if(col1!='',col1,col2);

I was looking for the same thing and I just found this list

Bootstrap 4 files do not come with the glyphicon support. But you can simply open up your bootstrap.css or bootstrap.min.css and paste this code which I came across here.

I had the same problem that is really easy to make, but took me a while to see through.

I had copied the declaration to where I was using it and had left the 'self' argument there, but it took me ages to realise that.

I had

self.myFunction(self, a, b, c='123')

but it should have been

self.myFunction(a, b, c='123')

SELECT id, GROUP_CONCAT(name SEPARATOR ' ') FROM table GROUP BY id;

https://dev.mysql.com/doc/refman/8.0/en/aggregate-functions.html#function_group-concat

From the link above, GROUP_CONCAT: This function returns a string result with the concatenated non-NULL values from a group. It returns NULL if there are no non-NULL values.

Python 3.3 introduces Python Launcher for Windows that is installed into c:\Windows\ as py.exe and pyw.exe by the installer. The installer also creates associations with .py and .pyw. Then add #!python3 or #!python2 as the first lline. No need to add anything to the PATH environment variable.

Update: Just install Python 3.3 from the official python.org/download. It will add also the launcher. Then add the first line to your script that has the .py extension. Then you can launch the script by simply typing the scriptname.py on the cmd line, od more explicitly by py scriptname.py, and also by double clicking on the scipt icon.

The py.exe looks for C:\PythonXX\python.exe where XX is related to the installed versions of Python at the computer. Say, you have Python 2.7.6 installed into C:\Python27, and Python 3.3.3 installed into C:\Python33. The first line in the script will be used by the Python launcher to choose one of the installed versions. The default (i.e. without telling the version explicitly) is to use the highest version of Python 2 that is available on the computer.

You can use jquery attr method

$("#delete").attr("hidden",true);

Scheme doesn't have algebraic data types or pattern matching but it's certainly a functional language. Annoying things about Python from a functional programming perspective:

1. Crippled Lambdas. Since Lambdas can only contain an expression, and you can't do everything as easily in an expression context, this means that the functions you can define "on the fly" are limited.

2. Ifs are statements, not expressions. This means, among other things, you can't have a lambda with an If inside it. (This is fixed by ternaries in Python 2.5, but it looks ugly.)

3. Guido threatens to remove map, filter, and reduce every once in a while

On the other hand, python has lexical closures, Lambdas, and list comprehensions (which are really a "functional" concept whether or not Guido admits it). I do plenty of "functional-style" programming in Python, but I'd hardly say it's ideal.

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte):

class BitArray {
  constructor(bits = 0) {
    this.uints = new Uint32Array(~~(bits / 32));
  }

  getBit(bit) {
    return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
  }

  assignBit(bit, value) {
    if (value) {
      this.uints[~~(bit / 32)] |= (1 << (bit % 32));
    } else {
      this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
    }
  }

  get size() {
    return this.uints.length * 32;
  }

  static bitsToUints(bits) {
    return ~~(bits / 32);
  }
}

Usage:

let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
  bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
  bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
  str += bits.getBit(bit);
}
str;

Output:

"00011011010000101000101100101010
 00011011010000101000101100101010

 11111111111111111111111111111111"

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!

For more info, see here:

• "How do you set, clear and toggle a single bit in JavaScript?": https://stackoverflow.com/a/1436448/1599699

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint32Array

Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array, JS only supports 32 bits:

Bitwise operators treat their operands as a sequence of 32 bits

...

The operands of all bitwise operators are converted to...32-bit integers

Jenkins has a link to their REST API in the bottom right of each page. This link appears on every page of Jenkins and points you to an API output for the exact page you are browsing. That should provide some understanding into how to build the API URls.

You can additionally use some wrapper, like I do, in Python, using http://jenkinsapi.readthedocs.io/en/latest/

Sample Array: Left ones are the keys, right one are my values

$array = array(
        'key-1' => 'value-1', 
        'key-2' => 'value-2',
        'key-3' => 'value-3',
        );

Example A: I want only the values of $array

foreach($array as $value) {    
    echo $value; // Through $value I get first access to 'value-1' then 'value-2' and to 'value-3'     
}

Example B: I want each value AND key of $array

foreach($array as $key => $value) {                 
    echo $value; // Through $value I get first access to 'value-1' then 'value-2' and to 'value-3'  

    echo $key; // Through $key I get access to 'key-1' then 'key-2' and finally 'key-3'    

    echo $array[$key]; // Accessing the value through $key = Same output as echo $value;
    $array[$key] = $value + 1; // Exmaple usage of $key: Change the value by increasing it by 1            
}

You can save the current scroll amount and then set it later:

var tempScrollTop = $(window).scrollTop();

..//Your code

$(window).scrollTop(tempScrollTop);

Partial solution: for a single string column tmp = df['A1'].fillna(''); isEmpty = tmp=='' gives boolean Series of True where there are empty strings or NaN values.

You can't do this in general, except at the window scope, where you can write window[objname].value = 'value';

If you are using Python2.5 or older try

from operator import mul
def factorial(n):
    return reduce(mul, range(1,n+1))

for newer Python, there is factorial in the math module as given in other answers here

As of python 2.7, optparse is deprecated, and will hopefully go away in the future.

argparse is better for all the reasons listed on its original page (https://code.google.com/archive/p/argparse/):

• handling positional arguments
• supporting sub-commands
• allowing alternative option prefixes like + and /
• handling zero-or-more and one-or-more style arguments
• producing more informative usage messages
• providing a much simpler interface for custom types and actions

More information is also in PEP 389, which is the vehicle by which argparse made it into the standard library.

For me .exists doesn't work, so I use the index :

if ($("#elem").index() ! = -1) {}

Here is it: http://www.htmlcssvqs.com/8ed/examples/chapter-17/webm-video-with-autoplay-loop.html You have to add the tags: autoplay="autoplay" loop="loop" or just "autoplay" and "loop".

My solution basically we have two string and with the & we get the right index:

res = ["Even", "Odd"]
print(res[x & 1])

Please note that it seems slower than other alternatives:

#!/usr/bin/env python3
import math
import random
from timeit import timeit

res = ["Even", "Odd"]

def foo(x):
    return res[x & 1]

def bar(x):
    if x & 1:
        return "Odd"
    return "Even"

la = lambda x : "Even" if not x % 2 else "Odd"

iter = 10000000

time = timeit('bar(random.randint(1, 1000))', "from __main__ import bar, random", number=iter)
print(time)
time = timeit('la(random.randint(1, 1000))', "from __main__ import la, random", number=iter)
print(time)
time = timeit('foo(random.randint(1, 1000))', "from __main__ import foo, random", number=iter)
print(time)

output:
8.05739480999182
8.170479692984372
8.892275177990086

Yet another solution.

Add ErrorControllers or static page to with 404 error information.

Modify your web.config (in case of controller).

<system.web>
    <customErrors mode="On" >
       <error statusCode="404" redirect="~/Errors/Error404" />
    </customErrors>
</system.web>

Or in case of static page

<system.web>
    <customErrors mode="On" >
        <error statusCode="404" redirect="~/Static404.html" />
    </customErrors>
</system.web>

This will handle both missed routes and missed actions.

If you're using .Net 3.5, you can make cleaner code using:

foreach (Record item in LookupCollection.Intersect(LargeCollection))
{
  //dostuff
}

I don't have .Net 3.5 here and so this is untested. It relies on an extension method. Not that LookupCollection.Intersect(LargeCollection) is probably not the same as LargeCollection.Intersect(LookupCollection) ... the latter is probably much slower.

This assumes LookupCollection is a HashSet

The best way might be if else with requesting. Also, this can be easier and clear to use.

Example:

<?php 
$go = $_REQUEST['go'];
?>
<?php if ($go == 'general_information'){?>
<div>
echo "hello";
}?>

Instead of using the functions that won't work well with PHP, especially when you have PHP in HTML.

When you try to access it as $result['context'], you treating it as an array, the error it's telling you that you are actually dealing with an object, then you should access it as $result->context

Underscore Mixins

Extending on @emil_lundberg's answer, you can also write a "mixin" if you're using Underscore to make a custom function for sorting if it's a kind of sorting you might repeat in an application somewhere.

For example, maybe you have a controller or view sorting results with sort order of "ASC" or "DESC", and you want to toggle between that sort, you could do something like this:

Mixin.js

_.mixin({
    sortByOrder: function(stooges, prop, order) {
      if (String(order) === "desc") {
          return _.sortBy(stooges, prop).reverse();
      } else if (String(order) === "asc") {
          return _.sortBy(stooges, prop);
      } else {
          return stooges;
      }
    }
})

Usage Example

var sort_order = "asc";
var stooges = [
  {name: 'moe', age: 40}, 
  {name: 'larry', age: 50}, 
  {name: 'curly', age: 60},
  {name: 'July', age: 35},
  {name: 'mel', age: 38}
 ];

_.mixin({
    sortByOrder: function(stooges, prop, order) {
    if (String(order) === "desc") {
        return _.sortBy(stooges, prop).reverse();
    } else if (String(order) === "asc") {
        return _.sortBy(stooges, prop);
    } else {
        return stooges;
    }
  }
})


// find elements
var banner = $("#banner-message");
var sort_name_btn = $("button.sort-name");
var sort_age_btn = $("button.sort-age");

function showSortedResults(results, sort_order, prop) {
    banner.empty();
    banner.append("<p>Sorting: " + prop + ', ' + sort_order + "</p><hr>")
  _.each(results, function(r) {
    banner.append('<li>' + r.name + ' is '+ r.age + ' years old.</li>');
  }) 
}

// handle click and add class
sort_name_btn.on("click", function() {
  sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'name', sort_order);
  showSortedResults(sortedResults, sort_order, 'name');
})

sort_age_btn.on('click', function() {
    sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'age', sort_order);
  showSortedResults(sortedResults, sort_order, 'age');
})

Here's a JSFiddle demonstrating this: JSFiddle for SortBy Mixin

It's pretty simple. You're trying to test the wrapper component generated by calling connect()(MyPlainComponent). That wrapper component expects to have access to a Redux store. Normally that store is available as context.store, because at the top of your component hierarchy you'd have a <Provider store={myStore} />. However, you're rendering your connected component by itself, with no store, so it's throwing an error.

You've got a few options:

• Create a store and render a <Provider> around your connected component
• Create a store and directly pass it in as <MyConnectedComponent store={store} /> , as the connected component will also accept "store" as a prop
• Don't bother testing the connected component. Export the "plain", unconnected version, and test that instead. If you test your plain component and your mapStateToProps function, you can safely assume the connected version will work correctly.

You probably want to read through the "Testing" page in the Redux docs: https://redux.js.org/recipes/writing-tests.

edit:

After actually seeing that you posted source, and re-reading the error message, the real problem is not with the SportsTopPane component. The problem is that you're trying to "fully" render SportsTopPane, which also renders all of its children, rather than doing a "shallow" render like you were in the first case. The line searchComponent = <SportsDatabase sportsWholeFramework="desktop" />; is rendering a component that I assume is also connected, and therefore expects a store to be available in React's "context" feature.

At this point, you have two new options:

• Only do "shallow" rendering of SportsTopPane, so that you're not forcing it to fully render its children
• If you do want to do "deep" rendering of SportsTopPane, you'll need to provide a Redux store in context. I highly suggest you take a look at the Enzyme testing library, which lets you do exactly that. See http://airbnb.io/enzyme/docs/api/ReactWrapper/setContext.html for an example.

Overall, I would note that you might be trying to do too much in this one component and might want to consider breaking it into smaller pieces with less logic per component.

@echo off

set workdir={your working dir. for example - C:\work } set iplist=%workdir%\IP-list.txt

setlocal enabledelayedexpansion

echo HOSTNAME,LONGNAME,IPADDRESS,STATE >%OUTPUT_FILE%
for /f %%i in (%iplist%) do (
    set SERVER_ADDRESS_I=UNRESOLVED
    set SERVER_ADDRESS_L=UNRESOLVED
    for /f "tokens=1,2,3" %%x in ('ping -a -n 1 %%i ^&^& echo SERVER_IS_UP') do (
    if %%x==Pinging set SERVER_ADDRESS_L=%%y
    if %%x==Pinging set SERVER_ADDRESS_I=%%z
        if %%x==SERVER_IS_UP (set SERVER_STATE=UP) else (set SERVER_STATE=DOWN)
    )
    echo %%i [!SERVER_ADDRESS_L::=!] !SERVER_ADDRESS_I::=! is !SERVER_STATE!
    echo %%i,!SERVER_ADDRESS_L::=!,!SERVER_ADDRESS_I::=!,!SERVER_STATE! >>%OUTPUT_FILE%
)

fun rotateArrow(view: View): Boolean {
    return if (view.rotation == 0F) {
        view.animate().setDuration(200).rotation(180F)
        true
    } else {
         view.animate().setDuration(200).rotation(0F)
         false
    }
}

I agree that the way to do is to redirect to the new controller in usual cases.

I came across a use case where I needed to display the same page to 2 different kind of users (backend user previewing the page of a frontend user) so in my opinion what I needed was genuinely to call the frontend controller from the backend controller.

I solved the problem by making the frontend method static and wrapping it in another method. Hope it helps!

//==========
// Frontend
//==========
function profile()
{
   //Access check

   //Get profile id
   $id = get_user_id();

   return self::_profile($id);
}

static function _profile($id)
{
   $CI = &get_instance();
   //Prepare page
   //Load view
}

//==========
// Backend
//==========
function preview_profile($id)
{
   $this->load->file('controllers/frontend.php', false);

   Frontend::_profile($id);
}

The easiest method would be to wrap them both in a container div and apply margin: 0 auto; to the container. This will center both the #page-wrap and the #sidebar divs on the page. However, if you want that off-center look, you could then shift the container 200px to the left, to account for the width of the #sidebar div.

This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.

Try this:

public class abc extends Activity implements OnPreparedListener{

  /** Called when the activity is first created. */

  @Override
    public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watch?v=cxLG2wtE7TM")));          


    @Override
      public void onPrepared(MediaPlayer mp) {
        // TODO Auto-generated method stub

    }
  }
}

whilst sometimes you might have multiple php versions, you might also have a held-back version of php-mysql.. do a sudo dpkg -l | grep mysql | grep php and compare what you get from php -v

You can achieve this using HTML and CSS and convert a checkbox into a HTML Switch.

HTML

      <div class="switch">
        <input id="cmn-toggle-1" class="cmn-toggle cmn-toggle-round"  type="checkbox">
        <label for="cmn-toggle-1"></label>
      </div>

CSS

input.cmn-toggle-round + label {

  width: 100px;
  height: 30px;
  background-color: #dddddd;
  -webkit-border-radius: 30px;
  -moz-border-radius: 30px;
  -ms-border-radius: 30px;
  -o-border-radius: 30px;
  border-radius: 30px;
}
input.cmn-toggle-round + label:before, input.cmn-toggle-round + label:after {
  display: block;
  position: absolute;
  top: 1px;
  left: 1px;
  bottom: 1px;
  content: "";

  background-color: #f1f1f1;
  -webkit-border-radius: 30px;

  background-color: #fff;
  -webkit-border-radius: 100%;
  -moz-border-radius: 100%;

  border-radius: 100%;
  -webkit-box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
  -moz-box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);

input.cmn-toggle-round:checked + label:before {
  background-color: #8ce196;
}
input.cmn-toggle-round:checked + label:after {
  margin-left: 60px;
}

.cmn-toggle {
  position: absolute;
  margin-left: -9999px;
  visibility: hidden;
}
.cmn-toggle + label {
  display: block;
  position: relative;
  cursor: pointer;
  outline: none;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

<div style="display: inline">Is this what you meant?</div>

Short answer

1. Reattach without ejecting others: screen -x
2. Get list of displays: ^A *, select the one to disconnect, press d

Explained answer

Background: When I was looking for the solution with same problem description, I have always landed on this answer. I would like to provide more sensible solution. (For example: the other attached screen has a different size and a I cannot force resize it in my terminal.)

Note: PREFIX is usually ^A = ctrl+a

Note: the display may also be called:

• "user front-end" (in at command manual in screen)
• "client" (tmux vocabulary where this functionality is detach-client)
• "terminal" (as we call the window in our user interface) /depending on

1. Reattach a session: screen -x

-x attach to a not detached screen session without detaching it

2. List displays of this session: PREFIX *

It is the default key binding for: PREFIX :displays. Performing it within the screen, identify the other display we want to disconnect (e.g. smaller size). (Your current display is displayed in brighter color/bold when not selected).

term-type   size         user interface           window       Perms
---------- ------- ---------- ----------------- ----------     -----
 screen     240x60         you@/dev/pts/2      nb  0(zsh)        rwx
 screen      78x40         you@/dev/pts/0      nb  0(zsh)        rwx

Using arrows ? ?, select the targeted display, press d If nothing happens, you tried to detach your own display and screen will not detach it. If it was another one, within a second or two, the entry will disappear.

Press ENTER to quit the listing.

Optionally: in order to make the content fit your screen, reflow: PREFIX F (uppercase F)

Excerpt from man page of screen:

displays

Shows a tabular listing of all currently connected user front-ends (displays). This is most useful for multiuser sessions. The following keys can be used in displays list:

• mouseclick Move to the selected line. Available when "mousetrack" is set to on.
• space Refresh the list
• d Detach that display
• D Power detach that display
• C-g, enter, or escape Exit the list
