Here is what needs to go in D1: =VLOOKUP(C1, $A$1:$B$4, 2, FALSE)

You should then be able to copy this down to the rest of column D.

I got the same error today and discovered that the firewall was blocking the svn client

Pass the ArrayList In argument.

    private static void order(ArrayList<Object> list) {

    Collections.sort(list, new Comparator() {

        public int compare(Object o2, Object o1) {

            String x1 =  o1.Date;
            String x2 =  o2.Date;

                return  x1.compareTo(x2);

        }
    });
}

With Haskell, you really don't need to think in recursions explicitly.

factorCount number = foldr factorCount' 0 [1..isquare] -
                     (fromEnum $ square == fromIntegral isquare)
    where
      square = sqrt $ fromIntegral number
      isquare = floor square
      factorCount' candidate
        | number `rem` candidate == 0 = (2 +)
        | otherwise = id

triangles :: [Int]
triangles = scanl1 (+) [1,2..]

main = print . head $ dropWhile ((< 1001) . factorCount) triangles

In the above code, I have replaced explicit recursions in @Thomas' answer with common list operations. The code still does exactly the same thing without us worrying about tail recursion. It runs (~ 7.49s) about 6% slower than the version in @Thomas' answer (~ 7.04s) on my machine with GHC 7.6.2, while the C version from @Raedwulf runs ~ 3.15s. It seems GHC has improved over the year.

PS. I know it is an old question, and I stumble upon it from google searches (I forgot what I was searching, now...). Just wanted to comment on the question about LCO and express my feelings about Haskell in general. I wanted to comment on the top answer, but comments do not allow code blocks.

Java and C:

• C used for low level functionalities and device connectivities
• Java used for Framework and Application Level

String text = new SimpleDateFormat("E, MMM d, yyyy").format(date);

I could be crazy but I'm finding these answers seriously bloated. Here's my solution

function serialiseForm(form) {
  var input = form.getElementsByTagName("input");
  var formData = {};
  for (var i = 0; i < input.length; i++) {
    formData[input[i].name] = input[i].value;
  }
  return formData = JSON.stringify(formData);
}

Assuming staff_id + date form a uk, this is another method:

SELECT STAFF_ID, SITE_ID, PAY_LEVEL
  FROM TABLE t
  WHERE END_ENROLLMENT_DATE is null
    AND DATE = (SELECT MAX(DATE)
                  FROM TABLE
                  WHERE staff_id = t.staff_id
                    AND DATE <= SYSDATE)

Thanks to A Ghazal, just what I needed. Here's a slightly cleaned up version of his(her) answer:

create FUNCTION [dbo].[fnMinutesToDuration]

)

-- Based on http://stackoverflow.com/questions/17733616/how-to-convert-number-of-minutes-to-hhmm-format-in-tsql

AS

return rtrim(isnull(cast(nullif((@minutes / 60)
                                , 0
                               ) as varchar
                        ) + 'h '

            + isnull(CAST(nullif((@minutes % 60)
                                 ,0
                                ) AS VARCHAR(2)
                         ) + 'm'
                     ,''
                    )
            )

end

My 5 cents:

1. Use async/await if and only if you do an IO operation, like DB or external service webservice.
2. Always prefer async calls to DB.
3. Each time you query the DB.

P.S. There are exceptional cases for point 1, but you need to have a good understanding of async internals for this.

As an additional advantage, you can do few IO calls in parallel if needed:

Task task1 = FooAsync(); // launch it, but don't wait for result
Task task2 = BarAsync(); // launch bar; now both foo and bar are running
await Task.WhenAll(task1, task2); // this is better in regard to exception handling
// use task1.Result, task2.Result

There are two possible approaches; either you create a unique value and store somewhere along with the creation time, for example in a database, or you put the creation time inside the token so that you can decode it later and see when it was created.

To create a unique token:

string token = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

Basic example of creating a unique token containing a time stamp:

byte[] time = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
byte[] key = Guid.NewGuid().ToByteArray();
string token = Convert.ToBase64String(time.Concat(key).ToArray());

To decode the token to get the creation time:

byte[] data = Convert.FromBase64String(token);
DateTime when = DateTime.FromBinary(BitConverter.ToInt64(data, 0));
if (when < DateTime.UtcNow.AddHours(-24)) {
  // too old
}

Note: If you need the token with the time stamp to be secure, you need to encrypt it. Otherwise a user could figure out what it contains and create a false token.

The size of the pointer may be something different than that of int. Also an implementation could produce better than simple hex value representation of the address when you use %p.

Note: this solution will work with WebClientSocket as well as with HttpWebRequest or any other class that uses WebHeaderCollection to work with headers.

If you look at the source code of WebHeaderCollection.cs you will see that Hinfo is used to keep information of all known headers:

private static readonly HeaderInfoTable HInfo = new HeaderInfoTable();

Looking at HeaderInfoTable class, you can notice all the data is stored into hash table

private static Hashtable HeaderHashTable;

Further, in static contructor of HeaderInfoTable, you can see all known headers are added in HeaderInfo array and then copied into hashtable.

Final look at HeaderInfo class shows the names of the fields.

internal class HeaderInfo {

    internal readonly bool IsRequestRestricted;
    internal readonly bool IsResponseRestricted;
    internal readonly HeaderParser Parser;

    //
    // Note that the HeaderName field is not always valid, and should not
    // be used after initialization. In particular, the HeaderInfo returned
    // for an unknown header will not have the correct header name.
    //

    internal readonly string HeaderName;
    internal readonly bool AllowMultiValues;
    ...
    }

So, with all the above, here is a code that uses reflection to find static Hashtable in HeaderInfoTable class and then changes every request-restricted HeaderInfo inside hash table to be unrestricted

        // use reflection to remove IsRequestRestricted from headerInfo hash table
        Assembly a = typeof(HttpWebRequest).Assembly;
        foreach (FieldInfo f in a.GetType("System.Net.HeaderInfoTable").GetFields(BindingFlags.NonPublic | BindingFlags.Static))
        {
            if (f.Name == "HeaderHashTable")
            {
                Hashtable hashTable = f.GetValue(null) as Hashtable;
                foreach (string sKey in hashTable.Keys)
                {

                    object headerInfo = hashTable[sKey];
                    //Console.WriteLine(String.Format("{0}: {1}", sKey, hashTable[sKey]));
                    foreach (FieldInfo g in a.GetType("System.Net.HeaderInfo").GetFields(BindingFlags.NonPublic | BindingFlags.Instance))
                    {

                        if (g.Name == "IsRequestRestricted")
                        {
                            bool b = (bool)g.GetValue(headerInfo);
                            if (b)
                            {
                                g.SetValue(headerInfo, false);
                                Console.WriteLine(sKey + "." + g.Name + " changed to false");
                            }

                        }
                    }

                }
            }
        }

You can do it using jsPDF

HTML:

<div id="content">
     <h3>Hello, this is a H3 tag</h3>

    <p>A paragraph</p>
</div>
<div id="editor"></div>
<button id="cmd">generate PDF</button>

JavaScript:

var doc = new jsPDF();
var specialElementHandlers = {
    '#editor': function (element, renderer) {
        return true;
    }
};

$('#cmd').click(function () {
    doc.fromHTML($('#content').html(), 15, 15, {
        'width': 170,
            'elementHandlers': specialElementHandlers
    });
    doc.save('sample-file.pdf');
});

You have writer.close(); in your code. So bash receives EOF on its stdin and exits. Then you get Broken pipe when trying to read from the stdoutof the defunct bash.

I just found this excellent little tutorial. broken link (Cached version)

I also followed Microsoft's tutorial which is nice, but I only needed pipes as well.

As you can see, you don't need configuration files and all that messy stuff.

By the way, he uses both HTTP and pipes. Just remove all code lines related to HTTP, and you'll get a pure pipe example.

There are many freewares to examine the certificates and key stores such as KeyStore Explorer.

Unzip the apk and open the META-INF/?.RSA file. ? shall be CERT or ANDROID or may be something else. It will display all the information associated with your apk.

If you also want to get the name of the foreign key column:

SELECT i.TABLE_SCHEMA, i.TABLE_NAME, 
       i.CONSTRAINT_TYPE, i.CONSTRAINT_NAME, 
       k.COLUMN_NAME, k.REFERENCED_TABLE_NAME, k.REFERENCED_COLUMN_NAME 
  FROM information_schema.TABLE_CONSTRAINTS i 
  LEFT JOIN information_schema.KEY_COLUMN_USAGE k 
       ON i.CONSTRAINT_NAME = k.CONSTRAINT_NAME 
 WHERE i.TABLE_SCHEMA = '<TABLE_NAME>' AND i.CONSTRAINT_TYPE = 'FOREIGN KEY' 
 ORDER BY i.TABLE_NAME;

Because you are choosing jre dir. and not JDK dir. JDK dir. is for instance (depending on update and whether it's 64 bit or 32 bit): C:\Program Files (x86)\Java\jdk1.7.0_45 In my case it's 32 bit JDK 1.7 update 45

You can run IIS on any port you like, as long as it does not conflict with other applications. I am using 88, 8888 and other easy to remember ports.

You can find the common used port here: PORT NUMBERS, and it is safer to choose an unassigned TCP port.

Quote:

The Dynamic and/or Private Ports are those from 49152 through 65535

If IIS is working and you have troubles with an ASP.NET applications, those links might be helpful:

• How to: Configure ASP.NET Applications for an ASP.NET Version
• ASP.NET and IIS Configuration
• ASP.NET IIS Registration Tool (Aspnet_regiis.exe)
• IIS and ASP.NET: The Application Pool

If you are still having troubles, it would be helpful to provide more information about your environment, the steps taken so far to solve the problem, and retagging the question (append asp.net for example)

With Kotlin, we can now make a generic function for this!

object RepeatHelper {
    fun repeatDelayed(delay: Long, todo: () -> Unit) {
        val handler = Handler()
        handler.postDelayed(object : Runnable {
            override fun run() {
                todo()
                handler.postDelayed(this, delay)
            }
        }, delay)
    }
}

And to use, just do:

val delay = 1000L
RepeatHelper.repeatDelayed(delay) {
    myRepeatedFunction()
}

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

The limit of requests in .Net can be configured from two properties together:

First

• Web.Config/system.web/httpRuntime/maxRequestLength
• Unit of measurement: kilobytes
• Default value 4096 KB (4 MB)
• Max. value 2147483647 KB (2 TB)

Second

• Web.Config/system.webServer/security/requestFiltering/requestLimits/maxAllowedContentLength (in bytes)
• Unit of measurement: bytes
• Default value 30000000 bytes (28.6 MB)
• Max. value 4294967295 bytes (4 GB)

References:

• http://www.whatsabyte.com/P1/byteconverter.htm
• https://www.iis.net/configreference/system.webserver/security/requestfiltering/requestlimits

Example:

<location path="upl">
   <system.web>
     <!--The default size is 4096 kilobytes (4 MB). MaxValue is 2147483647 KB (2 TB)-->
     <!-- 100 MB in kilobytes -->
     <httpRuntime maxRequestLength="102400" />
   </system.web>
   <system.webServer>
     <security>
       <requestFiltering>          
         <!--The default size is 30000000 bytes (28.6 MB). MaxValue is 4294967295 bytes (4 GB)-->
         <!-- 100 MB in bytes -->
         <requestLimits maxAllowedContentLength="104857600" />
       </requestFiltering>
     </security>
   </system.webServer>
 </location>

This might be trivial and not related to the OP's question, but I often made this mistaken at the beginning when I was learning scripting

VAR_NAME = $(hostname)
echo "the hostname is ${VAR_NAME}"  

This will produce 'command not found' response. The correct way is to eliminate the spaces

VAR_NAME=$(hostname)

Adding this here as it might help someone. I was having problems with Android showing the popup and invalid certificate error.

We have a Comodo Extended Validation certificate and we received the zip file that contained 4 files:

• AddTrustExternalCARoot.crt
• COMODORSAAddTrustCA.crt
• COMODORSAExtendedValidationSecureServerCA.crt
• www_mydomain_com.crt

I concatenated them together all on one line like so:

cat www_mydomain_com.crt COMODORSAExtendedValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt >www.mydomain.com.ev-ssl-bundle.crt

Then I used that bundle file as my ssl_certificate_key in nginx. That's it, works now.

Inspired by this gist: https://gist.github.com/ipedrazas/6d6c31144636d586dcc3

I use this trick, pretty sure I already posted it to a duplicate of this question:

-(void)tableViewDidLoadRows:(UITableView *)tableView{
    // do something after loading, e.g. select a cell.
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // trick to detect when table view has finished loading.
    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(tableViewDidLoadRows:) object:tableView];
    [self performSelector:@selector(tableViewDidLoadRows:) withObject:tableView afterDelay:0];

    // specific to your controller
    return self.objects.count;
}

Color hexadecimal notation is like following: #AARRGGBB

• A : alpha
• R : red
• G : green
• B : blue

You should first look at how hexadecimal works. You can write at most FF.

In order to accomplish this, all that we need is two annotations:

1. @JsonIgnore
2. @JsonProperty

Use @JsonIgnore on the class member and its getter, and @JsonProperty on its setter. A sample illustration would help to do this:

class User {

    // More fields here
    @JsonIgnore
    private String password;

    @JsonIgnore
    public String getPassword() {
        return password;
    }

    @JsonProperty
    public void setPassword(final String password) {
        this.password = password;
    }
}

Deny from all 

is an .htaccess command(the actual content of that file you are trying to view). Not a denial of being able to edit the file. Just reopen the .htaccess file in the text viewer of choice and make the alterations as you so desire, save it, then reupload it to your folder of choice.

Though I think inadvertently you are blocking even yourself from viewing said application once uploaded.

I would do something like:

order deny,allow
deny from all
allow from 127.0.0.1

which will deny everyone but the IP in the allow from line, which you would change the IP to match your IP which you can obtain from http://www.whatismyip.com/ or similar site.

Here's the trick I found that works better than MagicTextView's stroke IMO

@Override
protected void onDraw(Canvas pCanvas) {
    int textColor = getTextColors().getDefaultColor();
    setTextColor(mOutlineColor); // your stroke's color
    getPaint().setStrokeWidth(10);
    getPaint().setStyle(Paint.Style.STROKE);
    super.onDraw(pCanvas);
    setTextColor(textColor);
    getPaint().setStrokeWidth(0);
    getPaint().setStyle(Paint.Style.FILL);
    super.onDraw(pCanvas);
}

If you have cleanup you need to do on exit, you can also use 'trap' with the pseudo-signal ERR. This works the same way as trapping INT or any other signal; bash throws ERR if any command exits with a nonzero value:

# Create the trap with   
#    trap COMMAND SIGNAME [SIGNAME2 SIGNAME3...]
trap "rm -f /tmp/$MYTMPFILE; exit 1" ERR INT TERM
command1
command2
command3
# Partially turn off the trap.
trap - ERR
# Now a control-C will still cause cleanup, but
# a nonzero exit code won't:
ps aux | grep blahblahblah

Or, especially if you're using "set -e", you could trap EXIT; your trap will then be executed when the script exits for any reason, including a normal end, interrupts, an exit caused by the -e option, etc.

It is simple.

• Right click on the project
• Go to Properties
• Go to Run in Categories tree
• Set the Main Class in the right side panel.
• Build the project

Thats it. Hope this helps.

If Symfony 4 or 5, juste use this code (Where name is the name of your field):

$request->request->get('name');

The answer by Chinmay Kanchi is excellent but I wanted an example of a function which passes and returns a variables/arrays to a C++ code. I though I'd include it here in case it is useful to others.

Passing and returning an integer

The C++ code for a function which takes an integer and adds one to the returned value,

extern "C" int add_one(int i)
{
    return i+1;
}

Saved as file test.cpp, note the required extern "C" (this can be removed for C code). This is compiled using g++, with arguments similar to Chinmay Kanchi answer,

g++ -shared -o testlib.so -fPIC test.cpp

The Python code uses load_library from the numpy.ctypeslib assuming the path to the shared library in the same directory as the Python script,

import numpy.ctypeslib as ctl
import ctypes

libname = 'testlib.so'
libdir = './'
lib=ctl.load_library(libname, libdir)

py_add_one = lib.add_one
py_add_one.argtypes = [ctypes.c_int]
value = 5
results = py_add_one(value)
print(results)

This prints 6 as expected.

Passing and printing an array

You can also pass arrays as follows, for a C code to print the element of an array,

extern "C" void print_array(double* array, int N)
{
    for (int i=0; i<N; i++) 
        cout << i << " " << array[i] << endl;
}

which is compiled as before and the imported in the same way. The extra Python code to use this function would then be,

import numpy as np

py_print_array = lib.print_array
py_print_array.argtypes = [ctl.ndpointer(np.float64, 
                                         flags='aligned, c_contiguous'), 
                           ctypes.c_int]
A = np.array([1.4,2.6,3.0], dtype=np.float64)
py_print_array(A, 3)

where we specify the array, the first argument to print_array, as a pointer to a Numpy array of aligned, c_contiguous 64 bit floats and the second argument as an integer which tells the C code the number of elements in the Numpy array. This then printed by the C code as follows,

1.4
2.6
3.0

Above Answers are also correct

There are two Approach

1. Use webhooks
2. Run script for every specific minute to get fresh pull of docker images

I am just sharing script may be it will helpful for you! You can use it with cronjob, I tried succesfully on OSX

#!/bin/bash
##You can use below commented line for setting cron tab for running cron job and to store its O/P in one .txt file

# Example for the Docker Hub V2 API
# Returns all images and tags associated with a Docker Hub organization account.
# Requires 'jq': https://stedolan.github.io/jq/

# set username, password, and organization
# Filepath where your docker-compose file is present
FILEPATH="/Users/Swapnil/Documents/lamp-alpine"
# Your Docker hub user name

echo "Eecuting Script @ date and time in YmdHMS: $(date +%Y%m%d%H%M%S)"
set -e
PIDFILE=/Users/Swapnil/Documents/$IMGNAME/forever.pid
if [ -f $PIDFILE ]
then
  PID=$(cat $PIDFILE)
  ps -p $PID > /dev/null 2>&1
  if [ $? -eq 0 ]
  then
    echo "Process already running"
    exit 1
  else
    ## Process not found assume not running
    echo $$
    echo $$ > $PIDFILE
    if [ $? -ne 0 ]
    then
      echo "Could not create PID file"
      exit 1
    fi
  fi
else
  echo $$ > $PIDFILE
  if [ $? -ne 0 ]
  then
    echo "Could not create PID file"
    exit 1
  fi

A strange solution I found:

using Eclipse

• create simple (non-maven) java project
• add a Main class
• add all the jars to the classpath
• export Runnable JAR (it's important, because no other way here to do it)
• select Extract required libraries into generated JAR
• decide the licence issues
• tadammm...install the generated jar to your m2repo
• add this single dependency to your other projects.

cheers, Balint

There are a number of ways that you could do this, but the fastest might be to use IndexOf to find the index position of the letter you want to replace and then substring out the text before and after what you want to replace.

There's a better way to handle it using Native MongoDB code in Mongoose.

exports.getUsers = function(req, res, next) {

    var usersProjection = { 
        __v: false,
        _id: false
    };

    User.find({}, usersProjection, function (err, users) {
        if (err) return next(err);
        res.json(users);
    });    
}

http://docs.mongodb.org/manual/reference/method/db.collection.find/

Note:

var usersProjection

You want a block element that has what CSS calls shrink-to-fit width and the spec does not provide a blessed way to get such a thing. In CSS2, shrink-to-fit is not a goal, but means to deal with a situation where browser "has to" get a width out of thin air. Those situations are:

• float
• absolutely positioned element
• inline-block element
• table element

when there are no width specified. I heard they think of adding what you want in CSS3. For now, make do with one of the above.

The decision not to expose the feature directly may seem strange, but there is a good reason. It is expensive. Shrink-to-fit means formatting at least twice: you cannot start formatting an element until you know its width, and you cannot calculate the width w/o going through entire content. Plus, one does not need shrink-to-fit element as often as one may think. Why do you need extra div around your table? Maybe table caption is all you need.

Some addition to previous comments: 'firstboot' won't be available until you run 'mount_root' command.

So here is a full recap of what needs to be done. All manipulations I did on Windows 8.1.

• Enter Failsafe mode (hold the reset button on boot for a few seconds)
• Assign a static IP address, 192.168.1.2, to your PC. Example of a command: netsh interface ip set address name="Ethernet" static 192.168.1.2 255.255.255.0 192.168.1.1
• Connect to address 192.168.1.1 from telnet (I use PuTTY) and login/password isn't required).
• Run 'mount_root' (otherwise 'firstboot' won't be available).
• Run 'firstboot' to reset.
• Run 'reboot -f' to reboot.

Now you can enter to the router console from a browser. Also don't forget to return your PC from static to DHCP address assignment. Example: netsh interface ip set address name="Ethernet" source=dhcp

This answer is outdated. For Android 3.1 Studio go to this answer

One thing you can do is deactivate the external build. To do so click on "compiler settings icon" in the "Messages Make" panel that appears when you have an error. You can also open the compiler settings by going to File -> Settings -> Compiler. (Thanx to @maxgalbu for this tip).

Uncheck "Use External build"

And you will see the errors in the console

EDIT: After returning to "internal build" again you may get some errors, you can solve them this way: Android Studio: disabling "External build" to display error output create duplicate class errors

Since you using standard HTML you will need to define separate class for and manual set the rows to the classes.

This will first check if AutoFilterMode is set (filtering is possible), then check if FilterMode is on (you are filtering on something) then turn off filtering.

Regarding Errors, i.e. protection - se other answers

Context added (my script is looping over sheets, which are then saved as CSV, hence the need to remove filters - but keep AutoFilterMode on, if set:

For Each WS In ActiveWorkbook.Worksheets
  Select Case WS.Name
    Case "01", "02", "03", "04", "05"
      With WS
        If WS.AutoFilterMode Then
            If WS.FilterMode Then WS.ShowAllData
        End If

        ' Processing data
      End With
    Case Else
      ' Nothing to see here
  End Select
Next

Sounds like you're trying to execute the PHP code directly in your shell. Your shell doesn't speak PHP, so it interprets your PHP code as though it's in your shell's native language, as though you had literally run <?php at the command line.

Shell scripts usually start with a "shebang" line that tells the shell what program to use to interpret the file. Begin your file like this:

#!/usr/bin/env php
<?php
//Connection
function connection () {

Besides that, the string you're passing to exec doesn't make any sense. It starts with a slash all by itself, it uses too many periods in the path, and it has a stray right parenthesis.

Copy the contents of the command string and paste them at your command line. If it doesn't run there, then exec probably won't be able to run it, either.

Another option is to change the command you execute. Instead of running the script directly, run php and pass your script as an argument. Then you shouldn't need the shebang line.

exec('php name.php');

It's as easy as:

DECLARE @rv FLOAT;
SELECT @rv = rand();

And this will put a random number between 0-99 into a table:

CREATE TABLE R
(
    Number int
)

DECLARE @rv FLOAT;
SELECT @rv = rand();

INSERT INTO dbo.R
(Number)
    values((@rv * 100));

SELECT * FROM R

Try this simple in one line of code:-

$data= json_decode( json_encode($data), true);

Hope it helps :)

I think you are asking two things which are not necessarily the same

I want to extract every 6th element of the original

You can do this by indexing a sequence:

foo <- 1:120
foo[1:20*6]

I would like to create a vector in which each element is the i+6th element of another vector.

An easy way to do this is to supplement a logical factor with FALSEs until i+6:

foo <- 1:120
i <- 1
foo[1:(i+6)==(i+6)]
[1]   7  14  21  28  35  42  49  56  63  70  77  84  91  98 105 112 119

i <- 10
foo[1:(i+6)==(i+6)]
[1]  16  32  48  64  80  96 112

Ok, so in this application, there is an iframe in which the user is supplied with links or some capacity that allows that iframe to browse to some external site. You are then looking to capture the URL to which the user has browsed.

Something to keep in mind. Since the URL is to an external source, you will be limited in how much you can interact with this iframe via javascript (or an client side access for that matter), this is known as browser cross-domain security, as apparently you have discovered. There are clever work arounds, as presented here Cross-domain, cross-frame Javascript, although I do not think this work around applies in this case.

About all you can access is the location, as you need.

I would suggest making the code presented more resilitant and less error prone. Try browsing the web sometime with IE or FF configured to show javascript errors. You will be surprised just how many javascript errors are thrown, largely because there is a lot of error prone javascript out there, which just continues to proliferate.

This solution assumes that the iframe in question is the same "window" context where you are running the javascript. (Meaning, it is not embedded within another frame or iframe, in which case, the javascript code gets more involved, and you likely need to recursively search through the window hierarchy.)

<iframe name='frmExternal' id='frmExternal' src='http://www.stackoverflow.com'></frame>
<input type='text' id='txtUrl' />
<input type='button' id='btnGetUrl' value='Get URL' onclick='GetIFrameUrl();' />

<script language='javascript' type='text/javascript'>
function GetIFrameUrl()
{
    if (!document.getElementById)
    {
        return;
    }

    var frm = document.getElementById("frmExternal");
    var txt = document.getElementById("txtUrl");

    if (frm == null || txt == null)
    {
        // not great user feedback but slightly better than obnoxious script errors
       alert("There was a problem with this page, please refresh.");
       return;
    }

    txt.value = frm.src;
}
</script>

Hope this helps.

Moq cannot mock a static member of a class.

When designing code for testability it's important to avoid static members (and singletons). A design pattern that can help you refactoring your code for testability is Dependency Injection.

This means changing this:

public class Foo
{
    public Foo()
    {
        Bar = new Bar();
    }
}

to

public Foo(IBar bar)
{
    Bar = bar;
}

This allows you to use a mock from your unit tests. In production you use a Dependency Injection tool like Ninject or Unity wich can wire everything together.

I wrote a blog about this some time ago. It explains which patterns an be used for better testable code. Maybe it can help you: Unit Testing, hell or heaven?

Another solution could be to use the Microsoft Fakes Framework. This is not a replacement for writing good designed testable code but it can help you out. The Fakes framework allows you to mock static members and replace them at runtime with your own custom behavior.

Actually make sure your button type is Button not Submit, that caused status conflict where I met recently.

All you need to do is make an array of fields and then set it to the class you want like shown below.

Field fld[] = (class name).class.getDeclaredFields();   
for(Field x : fld)
{System.out.println(x);}

For example if you did

Field fld[] = Integer.class.getDeclaredFields();
          for(Field x : fld)
          {System.out.println(x);}

you would get

public static final int java.lang.Integer.MIN_VALUE
public static final int java.lang.Integer.MAX_VALUE
public static final java.lang.Class java.lang.Integer.TYPE
static final char[] java.lang.Integer.digits
static final char[] java.lang.Integer.DigitTens
static final char[] java.lang.Integer.DigitOnes
static final int[] java.lang.Integer.sizeTable
private static java.lang.String java.lang.Integer.integerCacheHighPropValue
private final int java.lang.Integer.value
public static final int java.lang.Integer.SIZE
private static final long java.lang.Integer.serialVersionUID

While gnuplot is powerful, it's also really irritating when you just want to pipe in a bunch of points and get a graph.

Thankfully, someone created eplot (easy plot), which handles all the nonsense for you.

                frame.setVisible(true);
            }
        });

    }
}

then drag this class to you jframe,and it's done

it's deprecated,but it works.........

Your elements need to have a position attribute. (e.g. absolute, relative, fixed) or z-index won't work.

If when you set disabled="disabled" immediately after the user clicks the button, and the form doesn't submit because of that, you could try two things:

//First choice [given myForm = your form]:
myInputButton.disabled = "disabled";
myForm.submit()

//Second choice:
setTimeout(disableFunction, 1);  
//so the form will submit and then almost instantly, the button will be disabled  

Although I honestly bet there will be a better way to do this, than that.

Not sure if this has already been said, but I had a similar problem with cells showing nothing in them, but not being blank when you run the IsBlank() formula.

I selected the entire column, selected Find & Replace, found cells with nothing and replaced with a 0, then ran find and replace again, finding cells with 0 and replacing with "".

This solved my problem and allowed me to search for Blank cells (F5, Special, Blanks) and delete rows that were blank....BOOM.

May not work for every application but this solved my problem.

Sometimes there are spaces in cells which appear blank but if you hit F2 on the cell, you'll see spaces. You can also search this way if you know the exact number of spaces in a cell

You can check your eav_attributes table to find the relevant attribute IDs for each image role, such as;

Then you can use those to set whichever role to any other role for all products like so;

UPDATE catalog_product_entity_varchar AS `v` INNER JOIN (SELECT `value`,`entity_id` FROM `catalog_product_entity_varchar` WHERE `attribute_id`=86) AS `j` ON `j`.`entity_id`=`v`.entity_id SET `v`.`value`=j.`value` WHERE `v`.attribute_id = 85 AND `v`.`entity_id`=`j`.`entity_id`

The above will set all your 'base' roles to the 'small' image of the same product.

For VS 2019 just use this powershell script:

Get-ChildItem "$($env:LOCALAPPDATA)\Microsoft\VisualStudio\16.0_*" | 
Foreach-Object {
  $dir = $_;
  $regFile = "$($dir.FullName)\privateregistry.bin";
  Write-Host "Loading $($dir.BaseName) from ``$regFile``"
  & reg load "HKLM\_TMPVS_" "$regFile"
  New-ItemProperty -Name "Guides" -Path "HKLM:\_TMPVS_\Software\Microsoft\VisualStudio\$($dir.BaseName)\Text Editor" -Value "RGB(255,0,0), 80" -force | Out-Null;
   
  Sleep -Seconds 5; # might take some time befor the file can be unloaded
  & reg unload "HKLM\_TMPVS_";
  Write-Host "Unloaded $($dir.BaseName) from ``$regFile``"
}

Like this

SELECT DISTINCT Table1.Column1
FROM Table1
WHERE NOT EXISTS( SELECT * FROM Table2
    WHERE Table1.Column1 = Table2.Column1  )

You want NOT EXISTS, not "Not Equal"

By the way, you rarely want to write a FROM clause like this:

FROM Table1, Table2

as this means "FROM all combinations of every row in Table1 with every row in Table2..." Usually that's a lot more result rows than you ever want to see. And in the rare case that you really do want to do that, the more accepted syntax is:

FROM Table1 CROSS JOIN Table2

The application name come from getContextPath.

I find this graphic from Agile Software Craftsmanship HttpServletRequest Path Decoding sorts out all the different methods that are available:

SOAP (Simple Object Access Protocol) is the communication protocol in the web service scenario.

One benefit of SOAP is that it allowas RPC to execute through a firewall. But to pass through a firewall, you will probably want to use 80. it uses port no.8084 To the firewall, a SOAP conversation on 80 looks like a POST to a web page. However, there are extensions in SOAP which are specifically aimed at the firewall. In the future, it may be that firewalls will be configured to filter SOAP messages. But as of today, most firewalls are SOAP ignorant.

so exclusively open SOAP Port in Firewalls

.aspx file in header section

<head>
    <script type="text/javascript">
        <%=YourScript %>
        function functionname1(arg1,arg2){content}
    </script>

.cs file

public string YourScript = "";
public string functionname(arg)
{
    if (condition)
    {
        YourScript = "functionname1(arg1,arg2);";
    }
}

Also it depends if you need to use a table element or not. You can imitate a table using CSS and make an A element the row

<div class="table" style="width:100%;">
  <a href="#" class="tr">
    <span class="td">
      cell 1
    </span>
    <span class="td">
      cell 2
    </span>
  </a>
</div>

css:

.table{display:table;}
.tr{display:table-row;}
.td{display:table-cell;}
.tr:hover{background-color:#ccc;}

As this question is already fully explained and discussed in existing answers I will just provide a neat pandas approach to the context manager using pandas.option_context (links to docs and example) - there is absolutely no need to create a custom class with all the dunder methods and other bells and whistles.

First the context manager code itself:

from contextlib import contextmanager

@contextmanager
def SuppressPandasWarning():
    with pd.option_context("mode.chained_assignment", None):
        yield

Then an example:

import pandas as pd
from string import ascii_letters

a = pd.DataFrame({"A": list(ascii_letters[0:4]), "B": range(0,4)})

mask = a["A"].isin(["c", "d"])
# Even shallow copy below is enough to not raise the warning, but why is a mystery to me.
b = a.loc[mask]  # .copy(deep=False)

# Raises the `SettingWithCopyWarning`
b["B"] = b["B"] * 2

# Does not!
with SuppressPandasWarning():
    b["B"] = b["B"] * 2

Worth noticing is that both approches do not modify a, which is a bit surprising to me, and even a shallow df copy with .copy(deep=False) would prevent this warning to be raised (as far as I understand shallow copy should at least modify a as well, but it doesn't. pandas magic.).

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install by setting the same environment variables.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip

Then once it's installed, use:

pip install --proxy="user:password@server:port" packagename

From the pip man page:

--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

When to use LIBXML_NOCDATA ?

I add the issue when transforming XML to JSON.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo json_encode($xml, true); 
/* prints
   {
     "content": {}
   }
 */

When accessing the SimpleXMLElement object, It gets the CDATA :

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>");
echo $xml->content; 
/* prints
   Hello, world!
*/

I makes sense to use LIBXML_NOCDATA because json_encode don't access the SimpleXMLElement to trigger the string casting feature, I'm guessing a __toString() equivalent.

$xml = simplexml_load_string("<foo><content><![CDATA[Hello, world!]]></content></foo>", null, LIBXML_NOCDATA);
echo json_encode($xml);
/*
 {
   "content": "Hello, world!"
 }
*/

There is the use case of a mirror of Docker Hub (such as Artifactory or a custom one), which I haven't seen mentioned here. This is one of the most valid cases where changing the default registry is needed.

Luckily, Docker (at least version 19.03.3) allows you to set a mirror (tested in Docker CE). I don't know if this will work with additional images pushed to that mirror that aren't on Docker Hub, but I do know it will use the mirror instead. Docker documentation: https://docs.docker.com/registry/recipes/mirror/#configure-the-docker-daemon.

Essentially, you need to add "registry-mirrors": [] to the /etc/docker/daemon.json configuration file. So if you have a mirror hosted at https://my-docker-repo.my.company.com, your /etc/docker/daemon.json should contain:

{
  "registry-mirrors": ["https://my-docker-repo-mirror.my.company.com"]
}

Afterwards, restart the Docker daemon. Now if you do a docker pull postgres:12, Docker should fetch the image from the mirror instead of directly from Docker Hub. This is much better than prepending all images with my-docker-repo.my.company.com

Be careful with the "Range(...)" without first qualifying a Worksheet because it will use the currently Active worksheet to make the copy from. It's best to fully qualify both sheets. Please give this a shot (please change "Sheet1" with the copy worksheet):

EDIT: edited for pasting values only based on comments below.

Private Sub CommandButton1_Click()
  Application.ScreenUpdating = False
  Dim copySheet As Worksheet
  Dim pasteSheet As Worksheet

  Set copySheet = Worksheets("Sheet1")
  Set pasteSheet = Worksheets("Sheet2")

  copySheet.Range("A3:E3").Copy
  pasteSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).PasteSpecial xlPasteValues

A foreign key with a cascade delete means that if a record in the parent table is deleted, then the corresponding records in the child table will automatically be deleted. This is called a cascade delete.

You are saying in a opposite way, this is not that when you delete from child table then records will be deleted from parent table.

UPDATE 1:

ON DELETE CASCADE option is to specify whether you want rows deleted in a child table when corresponding rows are deleted in the parent table. If you do not specify cascading deletes, the default behaviour of the database server prevents you from deleting data in a table if other tables reference it.

If you specify this option, later when you delete a row in the parent table, the database server also deletes any rows associated with that row (foreign keys) in a child table. The principal advantage to the cascading-deletes feature is that it allows you to reduce the quantity of SQL statements you need to perform delete actions.

So it's all about what will happen when you delete rows from Parent table not from child table.

So in your case when user removes entries from CATs table then rows will be deleted from books table. :)

Hope this helps you :)

If you need to popback from the fourth fragment in the backstack history to the first, use tags!!!

When you add the first fragment you should use something like this:

getFragmentManager.beginTransaction.addToBackStack("A").add(R.id.container, FragmentA).commit() 

or

getFragmentManager.beginTransaction.addToBackStack("A").replace(R.id.container, FragmentA).commit()

And when you want to show Fragments B,C and D you use this:

getFragmentManager.beginTransaction.addToBackStack("B").replace(R.id.container, FragmentB, "B").commit()

and other letters....

To return to Fragment A, just call popBackStack(0, "A"), yes, use the flag that you specified when you add it, and note that it must be the same flag in the command addToBackStack(), not the one used in command replace or add.

You're welcome ;)

If you're looking for a solution from Selenium RC, you can use simply

// assuming 'selenium' is a healthy Selenium instance
selenium.type("someLocator", "");

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.

SQL Query: (group by & count of distinct)

select city,count(distinct(emailId)) from TransactionDetails group by city;

Equivalent mongo query would look like this:

db.TransactionDetails.aggregate([ 
{$group:{_id:{"CITY" : "$cityName"},uniqueCount: {$addToSet: "$emailId"}}},
{$project:{"CITY":1,uniqueCustomerCount:{$size:"$uniqueCount"}} } 
]);

In Python 3, you can monkey-patch the print function, to always send flush=True:

_orig_print = print

def print(*args, **kwargs):
    _orig_print(*args, flush=True, **kwargs)

As pointed out in a comment, you can simplify this by binding the flush parameter to a value, via functools.partial:

print = functools.partial(print, flush=True)

I'd recommend getting the source with urllib and, if you're going to parse, use something like Beautiful Soup.

import urllib

url = urllib.urlopen("http://example.com") # Open the URL.
content = url.readlines() # Read the source and save it to a variable.

What you posted has a syntax error, but it makes no difference as you cannot pass HTTP headers via $.post().

Provided you're on jQuery version >= 1.5, switch to $.ajax() and pass the headers (docs) option. (If you're on an older version of jQuery, I will show you how to do it via the beforeSend option.)

$.ajax({
    url: 'https://url.com',
    type: 'post',
    data: {
        access_token: 'XXXXXXXXXXXXXXXXXXX'
    },
    headers: {
        Header_Name_One: 'Header Value One',   //If your header name has spaces or any other char not appropriate
        "Header Name Two": 'Header Value Two'  //for object property name, use quoted notation shown in second
    },
    dataType: 'json',
    success: function (data) {
        console.info(data);
    }
});

jQuery(".morepost").live("click", function() { 
var loadID = jQuery(this).attr('id'); //get the id 
alert(loadID);    
});

you can also get the value of id using .attr()

Sometimes you don't need third party libraries to parse JSON from text. Sometimes all you need it the following JS command, try it first:

        const res_data = JSON.parse(body);

In case others may find this useful: I found that by adding an initial empty cell to my list of search terms, a zero value will be returned instead of error.

={INDEX(SearchTerms!$A$1:$A$38,MAX(IF(ISERROR(SEARCH(SearchTerms!$A$1:$A$38,SearchCell)),0,1)*((SearchTerms!$B$1:$B$38)+1)))}

NB: Column A has the search terms, B is the row number index.

Html.Hidden and Html.HiddenFor used to generate name-value pairs which waited by action method in controller. Sample Usage(*):

@using (Html.BeginForm("RemoveFromCart", "Cart")) {
                    @Html.Hidden("ProductId", line.Product.ProductID)
                    @Html.HiddenFor(x => x.ReturnUrl)
                    <input class="btn btn-sm btn-warning"
                           type="submit" value="Remove" />
                }

If your action method wait for "ProductId" you have to generate this name in form via using (Html.Hidden or Html.HiddenFor) For the case it is not possible to generate this name with strongly typed model you simple write this name with a string thats "ProductId".

public ViewResult RemoveFromCart(int productId, string returnUrl){...}

If I had written Html.HiddenFor(x => line.Product.ProductID), the helper would render a hidden field with the name "line.Product.ProductID". The name of the field would not match the names of the parameters for the "RemoveFromCart" action method which waiting the name of "ProductId". This would prevent the default model binders from working, so the MVC Framework would not be able to call the method.

document.all is very old, you don't have to use it anymore.

To quote Nicholas Zakas:

For instance, when the DOM was young, not all browsers supported getElementById(), and so there was a lot of code that looked like this:

if(document.getElementById){  //DOM
    element = document.getElementById(id);
} else if (document.all) {  //IE
    element = document.all[id];
} else if (document.layers){  //Netscape < 6
    element = document.layers[id];
}

If you want to do this in pgadmin, it is much easier. It seems in postgressql, to add a auto increment to a column, we first need to create a auto increment sequence and add it to the required column. I did like this.

1) Firstly you need to make sure there is a primary key for your table. Also keep the data type of the primary key in bigint or smallint. (I used bigint, could not find a datatype called serial as mentioned in other answers elsewhere)

2)Then add a sequence by right clicking on sequence-> add new sequence. If there is no data in the table, leave the sequence as it is, don't make any changes. Just save it. If there is existing data, add the last or highest value in the primary key column to the Current value in Definitions tab as shown below.

3)Finally, add the line nextval('your_sequence_name'::regclass) to the Default value in your primary key as shown below.

Make sure the sequence name is correct here. This is all and auto increment should work.

one way is if you have a jdk installed , in bin folder there is a utility called jconsole(even visualvm can be used). Launch it and connect to the relevant java process and you can see what are the heap size settings set and many other details

When running headless or cli only, jConsole can be used over lan, if you specify a port to connect on when starting the service in question.

You can do it this way:

var o = new { Id = 1, Name = "Foo" };
var o1 = new { Id = 2, Name = "Bar" };

var array = new[] { o, o1 };
var list = array.ToList();

list.Add(new { Id = 3, Name = "Yeah" });

It seems a little "hacky" to me, but it works - if you really need to have a list and can't just use the anonymous array.

Sever > Data Export

Select database, and start export

Similar to @nicolaskruchten s answer you could do the following:

require(ggplot2)

df = data.frame(ID = c('P1', 'P1', 'P2', 'P2', 'P3', 'P3'),
                Value1 = c(100, 120, 300, 400, 130, 140),
                Value2 = c(12, 13, 11, 16, 15, 12))

ggplot(df) + 
  geom_line(data = ~.x[.x$ID %in% c("P1" , "P3"), ],
            aes(Value1, Value2, group = ID, colour = ID))

I am really surprised that no one has posted this yet

$(document).on('click','#my-butt', function(){
   console.log('document is always there');
}) 

If you are unsure about what elements are going to be on that page at that time just attach it to document.

Note: this is sub-optimal from performance perspective - to get maximum speed one should try to attach to the nearest parent of element that is going to be inserted.

This will convert the whole column:

select from_unixtime(unix_timestamp(transaction_date,'yyyyMMdd')) from table1

In case of circle all you need is one div, but in case of hollow square you need to have 2 divs. The divs are having a display of inline-block which you can change accordingly. Live Codepen link: Click Me

In case of circle all you need to change is the border properties and the dimensions(width and height) of circle. If you want to change color just change the border color of hollow-circle.

In case of the square background-color property needs to be changed depending upon the background of page or the element upon which you want to place the hollow-square. Always keep the inner-circle dimension small as compared to the hollow-square. If you want to change color just change the background-color of hollow-square. The inner-circle is centered upon the hollow-square using the position, top, left, transform properties just don't mess with them.

Vertical alignment doesn't work with floated elements, indeed. That's because float lifts the element from the normal flow of the document. You might want to use other vertical aligning techniques, like the ones based on transform, display: table, absolute positioning, line-height, js (last resort maybe) or even the plain old html table (maybe the first choice if the content is actually tabular). You'll find that there's a heated debate on this issue.

However, this is how you can vertically align YOUR 3 divs:

.wrap{
    width: 500px;
    overflow:hidden;    
    background: pink;
}

.left {
    width: 150px;       
    margin-right: 10px;
    background: yellow;  
    display:inline-block;
    vertical-align: middle; 
}

.left2 {
    width: 150px;    
    margin-right: 10px;
    background: aqua; 
    display:inline-block;
    vertical-align: middle; 
}

.right{
    width: 150px;
    background: orange;
    display:inline-block;
    vertical-align: middle; 
}

Not sure why you needed both fixed width, display: inline-block and floating.

You can use:

• String.TrimStart - Removes all leading occurrences of a set of characters specified in an array from the current String object.
• String.TrimEnd - Removes all trailing occurrences of a set of characters specified in an array from the current String object.
• String.Trim - combination of the two functions above

Usage:

string txt = "                   i am a string                                    ";
char[] charsToTrim = { ' ' };    
txt = txt.Trim(charsToTrim)); // txt = "i am a string"

EDIT:

txt = txt.Replace(" ", ""); // txt = "iamastring"   

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

I was also searching same answer, because at some point of time I needed total_count with distinct values along with limit/offset.

Because it's little tricky to do- To get total count with distinct values along with limit/offset. Usually it's hard to get total count with limit/offset. Finally I got the way to do -

SELECT DISTINCT COUNT(*) OVER() as total_count, * FROM table_name limit 2 offset 0;

Query performance is also high.

DateFormatter has some factory date styles for those too lazy to tinker with formatting strings. If you don't need a custom style, here's another option:

extension Date {  
  func asString(style: DateFormatter.Style) -> String {
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = style
    return dateFormatter.string(from: self)
  }
}

This gives you the following styles:

short, medium, long, full

Example usage:

let myDate = Date()
myDate.asString(style: .full)   // Wednesday, January 10, 2018
myDate.asString(style: .long)   // January 10, 2018
myDate.asString(style: .medium) // Jan 10, 2018
myDate.asString(style: .short)  // 1/10/18

Try this example

CREATE PROCEDURE MyProc
BEGIN
    --Stored Procedure variables
    Declare @maxOr int; 
    Declare @maxCa int; 

    --Getting query result in the variable (first variant of syntax)
    SET @maxOr = (SELECT MAX(orId) FROM [order]); 

    --Another variant of seting variable from query
    SELECT @maxCa=MAX(caId) FROM [cart]; 

    --Updating record through the variable
    INSERT INTO [order_cart] (orId,caId)
    VALUES(@maxOr, @maxCa); 

    --return values to the program as dataset
    SELECT
       @maxOr AS maxOr,
       @maxCa AS maxCa

    -- return one int value as "return value"
    RETURN @maxOr
END
GO

SQL-command to call the stored procedure

EXEC MyProc

Assuming your regular expression is correct:

inside your script tags

function validateEmail(emailField){
        var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;

        if (reg.test(emailField.value) == false) 
        {
            alert('Invalid Email Address');
            return false;
        }

        return true;

}

in your textfield:

<input type="text" onblur="validateEmail(this);" />

    first = [1,2,3,4,5]
    second = [6,7,8,9,10]
    #one way
    third = [x + y for x, y in zip(first, second)]
    print("third" , third) 
    #otherway
    fourth = []
    for i,j in zip(first,second):
        global fourth
        fourth.append(i + j)
    print("fourth" , fourth )
#third [7, 9, 11, 13, 15]
#fourth [7, 9, 11, 13, 15]

That depends on what the issue is. If it's to clone and modify the environment one solution could be:

subprocess.Popen(my_command, env=dict(os.environ, PATH="path"))

But that somewhat depends on that the replaced variables are valid python identifiers, which they most often are (how often do you run into environment variable names that are not alphanumeric+underscore or variables that starts with a number?).

Otherwise you'll could write something like:

subprocess.Popen(my_command, env=dict(os.environ, 
                                      **{"Not valid python name":"value"}))

In the very odd case (how often do you use control codes or non-ascii characters in environment variable names?) that the keys of the environment are bytes you can't (on python3) even use that construct.

As you can see the techniques (especially the first) used here benefits on the keys of the environment normally is valid python identifiers, and also known in advance (at coding time), the second approach has issues. In cases where that isn't the case you should probably look for another approach.

This should work:

string url = "http://example.com/file?a=1&b=2&c=string%20param";
string querystring = url.Substring(url.IndexOf('?'));
System.Collections.Specialized.NameValueCollection parameters = 
   System.Web.HttpUtility.ParseQueryString(querystring);

According to MSDN. Not the exact collectiontype you are looking for, but nevertheless useful.

Edit: Apparently, if you supply the complete url to ParseQueryString it will add 'http://example.com/file?a' as the first key of the collection. Since that is probably not what you want, I added the substring to get only the relevant part of the url.

You should use the StringFormat on the Binding. You can use either standard string formats, or custom string formats:

<TextBox Text="{Binding Value, StringFormat=N2}" />
<TextBox Text="{Binding Value, StringFormat={}{0:#,#.00}}" />

Note that the StringFormat only works when the target property is of type string. If you are trying to set something like a Content property (typeof(object)), you will need to use a custom StringFormatConverter (like here), and pass your format string as the ConverterParameter.

Edit for updated question

So, if your ViewModel defines the precision, I'd recommend doing this as a MultiBinding, and creating your own IMultiValueConverter. This is pretty annoying in practice, to go from a simple binding to one that needs to be expanded out to a MultiBinding, but if the precision isn't known at compile time, this is pretty much all you can do. Your IMultiValueConverter would need to take the value, and the precision, and output the formatted string. You'd be able to do this using String.Format.

However, for things like a ContentControl, you can much more easily do this with a Style:

<Style TargetType="{x:Type ContentControl}">
    <Setter Property="ContentStringFormat" 
            Value="{Binding Resolution, StringFormat=N{0}}" />
</Style>

Any control that exposes a ContentStringFormat can be used like this. Unfortunately, TextBox doesn't have anything like that.

Greg Hewgill's approach was missing a few components: the leading "^" to only match the start of the string, and compiling the re beforehand. But this approach will allow you to avoid a try: exept:

import re
INT_RE = re.compile(r"^[-]?\d+$")
def RepresentsInt(s):
    return INT_RE.match(str(s)) is not None

I would be interested why you are trying to avoid try: except?

Do not try to prevent SQL injection by sanitizing input data.

Instead, do not allow data to be used in creating your SQL code. Use Prepared Statements (i.e. using parameters in a template query) that uses bound variables. It is the only way to be guaranteed against SQL injection.

Please see my website http://bobby-tables.com/ for more about preventing SQL injection.

Try checking for the :visible property instead.

if($('#car2').not(':visible'))
{
    alert('car 2 is hidden');       
}

You mean like this?

void foo ( int i ) {
    if ( i < 0 ) return; // do nothing
    // do something
}

Guava offers Lists#reverse(List) and ImmutableList#reverse(). As in most cases for Guava, the former delegates to the latter if the argument is an ImmutableList, so you can use the former in all cases. These do not create new copies of the list but just "reversed views" of it.

Example

List reversed = ImmutableList.copyOf(myList).reverse();

I know this is an old post and that it wants an answer for .NET 1.1 but there's already a very good answer for that. I thought it would be good to have an answer for those people who land on this post that may have a more recent version of the .Net framework, such as myself when I went looking for an answer to the same question.

In those cases there is an even simpler way to write the contents of a StringBuilder to a text file. It can be done with one line of code. It may not be the most efficient but that wasn't really the question now was it.

System.IO.File.WriteAllText(@"C:\MyDir\MyNewTextFile.txt",sbMyStringBuilder.ToString());

Don't call write.close() in writeToFile().

because u have to have jquery set-up to enable the toggling functionality of the toggler button. So, all u have to do is to add bootstrap.bundle.js before bootstrap.css:

<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

In some cases, it's possible to automatically parallelize loops using Numba, though it only works with a small subset of Python:

from numba import njit, prange

@njit(parallel=True)
def prange_test(A):
    s = 0
    # Without "parallel=True" in the jit-decorator
    # the prange statement is equivalent to range
    for i in prange(A.shape[0]):
        s += A[i]
    return s

Unfortunately, it seems that Numba only works with Numpy arrays, but not with other Python objects. In theory, it might also be possible to compile Python to C++ and then automatically parallelize it using the Intel C++ compiler, though I haven't tried this yet.

As you said..

$Gender  = isset($_POST["gender"]); ' it returns a empty string 

because, you haven't mention method type either use POST or GET, by default it will use GET method. On the other side, you are trying to retrieve your value by using POST method, but in the form you haven't mentioned POST method. Which means miss-match method will result for empty.

Try this code..

<form name="signup_form"  action="./signup.php" onsubmit="return validateForm()"   method="post">
<table> 
  <tr> <td> First Name    </td><td> <input type="text" name="fname" size=10/></td></tr>
  <tr> <td> Last Name     </td><td> <input type="text" name="lname" size=10/></td></tr>
  <tr> <td> Your Email    </td><td> <input type="text" name="email" size=10/></td></tr>
  <tr> <td> Re-type Email </td><td> <input type="text" name="remail"size=10/></td></tr>
  <tr> <td> Password      </td><td> <input type="password" name="paswod" size=10/> </td></tr>
  <tr> <td> Gender        </td><td> <select name="gender">
  <option value="select">                Select </option>    
  <option value="male">   Male   </option>
  <option value="female"> Female </option></select></td></tr> 
  <tr> <td> <input type="submit" value="Sign up" id="signup"/> </td> </tr>
 </table>
 </form>

and on signup page

$Gender  = $_POST["gender"];

i'm sure.. now, you will get the value..

You could set both left and right property to 0. This will make the div stretch to the document width, but requires that no parent element is positioned (which is not the case, seeing as #header is position: relative;)

#site_nav_global_primary {    
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
}

Demo at: http://jsfiddle.net/xWnq2/, where I removed position:relative; from #header

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.

In the end, I stumbled upon this web page, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

Use the below code to convert a php array to CSV

<?php
   $ROW=db_export_data();//Will return a php array
   header("Content-type: application/csv");
   header("Content-Disposition: attachment; filename=test.csv");
   $fp = fopen('php://output', 'w');

   foreach ($ROW as $row) {
        fputcsv($fp, $row);
   }
   fclose($fp);

Try to change like this ..

firstStr = "<?xml version" 'my file always starts like this

Do until objInputFile.AtEndOfStream  

    strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/DD/Beginning_of_DD_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_DD_TC" & CStr(index) & "</a></td></tr>"  

   substrToFind = "<tr><td><a href=" & chr(34) & "../Test case " & trim(cstr((index)))

   tmpStr = objInputFile.ReadLine

   If InStr(tmpStr, substrToFind) <= 0 Then
       If Instr(tmpStr, firstStr) > 0 Then
          text = tmpStr 'to avoid the first empty line
       Else
          text = text & vbCrLf & tmpStr
       End If
   Else
      text = text & vbCrLf & strToAdd & vbCrLf & tmpStr

   End If
   index = index + 1
Loop

If your'e using Web Forms then Grid View can work very nicely for this

The code looks a little like this.

aspx page.

<asp:GridView ID="GridView1" runat="server" DataKeyNames="Name,Size,Quantity,Amount,Duration"></asp:GridView>

You can either input the data manually or use the source method in the code side

public class Room
{
    public string Name
    public double Size {get; set;}
    public int Quantity {get; set;}
    public double Amount {get; set;}
    public int Duration {get; set;}
}

protected void Page_Load(object sender, EventArgs e)
{
    if(!IsPostBack)//this is so you can keep any data you want for the list
    {
        List<Room> rooms=new List<Room>();
        //then use the rooms.Add() to add the rooms you need.
        GridView1.DataSource=rooms
        GridView1.Databind()
    }
}

Personally I like MVC4 the client side code ends up much lighter than Web Forms. It is similar to the above example with using a class but you use a view and Controller instead.

The View would look like this.

@model YourProject.Model.IEnumerable<Room>

<table>
    <th>
        <td>@Html.LabelFor(model => model.Name)</td>
        <td>@Html.LabelFor(model => model.Size)</td>
        <td>@Html.LabelFor(model => model.Quantity)</td>
        <td>@Html.LabelFor(model => model.Amount)</td>
        <td>@Html.LabelFor(model => model.Duration)</td>
   </th>
foreach(item in model)
{
    <tr>
        <td>@model.Name</td>
        <td>@model.Size</td>
        <td>@model.Quantity</td>
        <td>@model.Amount</td>
        <td>@model.Duration</td>
   </tr>
}
</table>

The controller might look something like this.

public ActionResult Index()
{
    List<Room> rooms=new List<Room>();
    //again add the items you need

    return View(rooms);
}

Hope this helps :)

Yes, this is possible and I would like to provide a slight alternative to Rajeev's answer that does not pass a php-generated datetime formatted string to the query.

The important distinction about how to declare the values to be SET in the UPDATE query is that they must not be quoted as literal strings.

To prevent CodeIgniter from doing this "favor" automatically, use the set() method with a third parameter of false.

$userId = 444;
$this->db->set('Last', 'Current', false);
$this->db->set('Current', 'NOW()', false);
$this->db->where('Id', $userId);
// return $this->db->get_compiled_update('Login');  // uncomment to see the rendered query
$this->db->update('Login');
return $this->db->affected_rows();  // this is expected to return the integer: 1

The generated query (depending on your database adapter) would be like this:

UPDATE `Login` SET Last = Current, Current = NOW() WHERE `Id` = 444

Demonstrated proof that the query works: https://www.db-fiddle.com/f/vcc6PfMcYhDD87wZE5gBtw/0

In this case, Last and Current ARE MySQL Keywords, but they are not Reserved Keywords, so they don't need to be backtick-wrapped.

If your precise query needs to have properly quoted identifiers (table/column names), then there is always protectIdentifiers().

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

Go to Start->All Programs-> Microsoft SQL Server 2012-> Configuration Tool -> Click SQL Server Configuration Manager.

If you see that SQL Server/ SQL Server Browser State is 'stopped'.Right click on SQL Server/SQL Server Browser and click start. In some cases above state can stop though TCP connection to port 1433 is assigned.

I did everything from visiting http://www.google.com/accounts/DisplayUnlockCaptcha to setting up 2-fa and creating an application password. The only thing that worked was logging into http://mail.google.com and sending an email from the server itself.

This solution will work for all versions of Android. You can use reflection in Java to make it work for all Android devices:

Basically you should create a reflection wrapper to call the Android 2.2 setDisplayOrientation, instead of calling the specific method.

The method:

    protected void setDisplayOrientation(Camera camera, int angle){
    Method downPolymorphic;
    try
    {
        downPolymorphic = camera.getClass().getMethod("setDisplayOrientation", new Class[] { int.class });
        if (downPolymorphic != null)
            downPolymorphic.invoke(camera, new Object[] { angle });
    }
    catch (Exception e1)
    {
    }
}

And instead of using camera.setDisplayOrientation(x) use setDisplayOrientation(camera, x) :

    if (Integer.parseInt(Build.VERSION.SDK) >= 8)
        setDisplayOrientation(mCamera, 90);
    else
    {
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT)
        {
            p.set("orientation", "portrait");
            p.set("rotation", 90);
        }
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
        {
            p.set("orientation", "landscape");
            p.set("rotation", 90);
        }
    }   

if you have xcopy, you can use the /E param, which will copy directories and subdirectories and the files within them, including maintaining the directory structure for empty directories

xcopy [source] [destination] /E

Don't forget the ∧ (logical and) and ∨ (logical or) characters, that's what I use for indicating sort direction: HTML entities ∧ & ∨ respectively.

rsync command can do the trick only if the last directory in the destination path doesn't exist, e.g. for the destination path of ~/bar/baz/ if bar exists but baz doesn't, then the following command can be used:

rsync -av --remove-source-files foo.c ~/bar/baz/

-a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
-v, --verbose               increase verbosity
--remove-source-files   sender removes synchronized files (non-dir)

In this case baz directory will be created if it doesn't exist. But if both bar and baz don't exist rsync will fail:

sending incremental file list
rsync: mkdir "/root/bar/baz" failed: No such file or directory (2)
rsync error: error in file IO (code 11) at main.c(657) [Receiver=3.1.2]

So basically it should be safe to use rsync -av --remove-source-files as an alias for mv.

You can use the "i" (as in idiv, imul..) version, and it doesn't look half bad:

image /= (image.max()/255.0)

For the other case you can write a function to normalize an n-dimensional array by colums:

def normalize_columns(arr):
    rows, cols = arr.shape
    for col in xrange(cols):
        arr[:,col] /= abs(arr[:,col]).max()

installed openssl on mac with brew but nothing found on /usr/local/bin where other brew installed bins are located. Found my fresh openssl here:

/usr/local/opt/openssl/bin/openssl

Run it like this:

/usr/local/opt/openssl/bin/openssl version

I don't want to update OS X openssl, while some OS stuff or other 3rd party apps may have dependency on older version.

I also don't mind longer path than just openssl

Writing this here for all the Googlers who are looking for location of openssl installed by brew.

After you write to the MemoryStream and before you read it back, you need to Seek back to the beginning of the MemoryStream so you're not reading from the end.

UPDATE

After seeing your update, I think there's a more reliable way to build the stream:

UnicodeEncoding uniEncoding = new UnicodeEncoding();
String message = "Message";

// You might not want to use the outer using statement that I have
// I wasn't sure how long you would need the MemoryStream object    
using(MemoryStream ms = new MemoryStream())
{
    var sw = new StreamWriter(ms, uniEncoding);
    try
    {
        sw.Write(message);
        sw.Flush();//otherwise you are risking empty stream
        ms.Seek(0, SeekOrigin.Begin);

        // Test and work with the stream here. 
        // If you need to start back at the beginning, be sure to Seek again.
    }
    finally
    {
        sw.Dispose();
    }
}

As you can see, this code uses a StreamWriter to write the entire string (with proper encoding) out to the MemoryStream. This takes the hassle out of ensuring the entire byte array for the string is written.

Update: I stepped into issue with empty stream several time. It's enough to call Flush right after you've finished writing.

if you want infos from the actual running batchfile, try this :

@echo off
set myNameFull=%0
echo myNameFull     %myNameFull%
set myNameShort=%~n0
echo myNameShort    %myNameShort%
set myNameLong=%~nx0
echo myNameLong     %myNameLong%
set myPath=%~dp0
echo myPath         %myPath%
set myLogfileWpath=%myPath%%myNameShort%.log
echo myLogfileWpath %myLogfileWpath%

more samples? C:> HELP CALL

%0 = parameter 0 = batchfile %1 = parameter 1 - 1st par. passed to batchfile... so you can try that stuff (e.g. "~dp") between 1st (e.g. "%") and last (e.g. "1") also for parameters

Just like what Nick is trying to say, something from outside is triggering the event twice. To solve that you should use event.stopPropagation() to prevent the parent element from bubbling.

$('button').click(function(event) {
    event.stopPropagation();
});

I hope this helps.

srand(time(NULL));

int nRandonNumber = rand()%((nMax+1)-nMin) + nMin;
printf("%d\n",nRandonNumber);

Thanks to thetalkingwalnut with answer Windows batch command(s) to read first line from text file I came up with the following solution:

@echo off
for /f "delims=" %%a in ('type sample.txt') do (
echo %%a
exit /b
)

You can use the comparison operators to compare strings. A strcmp function could be defined like this:

function strcmp(a, b) {
    if (a.toString() < b.toString()) return -1;
    if (a.toString() > b.toString()) return 1;
    return 0;
}

Edit    Here’s a string comparison function that takes at most min { length(a), length(b) } comparisons to tell how two strings relate to each other:

function strcmp(a, b) {
    a = a.toString(), b = b.toString();
    for (var i=0,n=Math.max(a.length, b.length); i<n && a.charAt(i) === b.charAt(i); ++i);
    if (i === n) return 0;
    return a.charAt(i) > b.charAt(i) ? -1 : 1;
}

In python \ (backslash) is used as an escape character. What this means that in places where you wish to insert a special character (such as newline), you would use the backslash and another character (\n for newline)

With your example string you would notice that when you put "C:\Users\Josh\Desktop\20130216" in the repl you will get "C:\\Users\\Josh\\Desktop\x8130216". This is because \2 has a special meaning in a python string. If you wish to specify \ then you need to put two \\ in your string.

"C:\\Users\\Josh\\Desktop\\28130216"

The other option is to notify python that your entire string must NOT use \ as an escape character by pre-pending the string with r

r"C:\Users\Josh\Desktop\20130216"

This is a "raw" string, and very useful in situations where you need to use lots of backslashes such as with regular expression strings.

In case you still wish to replace that single \ with \\ you would then use:

directory = string.replace(r"C:\Users\Josh\Desktop\20130216", "\\", "\\\\")

Notice that I am not using r' in the last two strings above. This is because, when you use the r' form of strings you cannot end that string with a single \

Why can't Python's raw string literals end with a single backslash?

Interfaces are only at compile time. This allows only you to check that the expected data received follows a particular structure. For this you can cast your content to this interface:

this.http.get('...')
    .map(res => <Product[]>res.json());

See these questions:

• How do I cast a JSON object to a typescript class
• How to get Date object from json Response in typescript

You can do something similar with class but the main differences with class are that they are present at runtime (constructor function) and you can define methods in them with processing. But, in this case, you need to instantiate objects to be able to use them:

this.http.get('...')
    .map(res => {
      var data = res.json();
      return data.map(d => {
        return new Product(d.productNumber,
          d.productName, d.productDescription);
      });
    });

String phoneNumberstr = "Tel: 00971-557890-999";
String numberRefined = phoneNumberstr.replaceAll("[^\\d-]", "");

result: 0097-557890-999

if you also do not need "-" in String you can do like this:

String phoneNumberstr = "Tel: 00971-55 7890 999";      
String numberRefined = phoneNumberstr.replaceAll("[^0-9]", "");

result: 0097557890999

I prefer not to use awk and such in scripts.. ip has the option to output in JSON.

If you leave out $interface then you get all of the ip addresses:

ip -json addr show $interface | \
  jq -r '.[] | .addr_info[] | select(.family == "inet") | .local'

You can use the BackgroundWorker RunWorkerAsync method and pass in your value.

If unspecified, the sum is computed by adding the layout_weight of all of the children. This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0. Must be a floating point value, such as "1.2"

Here is a video from Google Developers showing how to list all videos in a channel in v3 of the YouTube API.

There are two steps:

1. Query Channels to get the "uploads" Id. eg https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails

2. Use this "uploads" Id to query PlaylistItems to get the list of videos. eg https://www.googleapis.com/youtube/v3/playlistItems?playlistId={"uploads" Id}&key={API key}&part=snippet&maxResults=50

Conditional comment is a comment starts with <!--[if IE]> which couldn't be read by any browser except IE.

from 2011 Conditional comment isn't supported starting form IE 10 as announced by Microsoft in that time https://msdn.microsoft.com/en-us/library/hh801214(v=vs.85).aspx

The only option to use the Conditional comments is to request IE to run your site as IE 9 which supports the Conditional comments.

you can write your own css and/or js files for ie only and other browsers won't load or execute it.

this code snippet shows how to make IE 10 or 11 run ie-only.css and ie-only.js which contains custom codes to solve IE compatibility issues.

    <html>
      <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">
      <!--[if IE]>
            <meta http-equiv="Content-Type" content="text/html; charset=Unicode">
            <link rel="stylesheet" type="text/css" href='/css/ie-only.css' />

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:

• What IDE to use for Python?
• Which editor/IDE should I use for Python?

There is a Ubuntu solution available either through the Ubuntu Software Center or through the Synaptic Package Manager. This will connect Python version 3.4.0 to MySQL. Download "python3-mysql.connector" version 1.1.6-1.

Note that the connection syntax does not use "MySQLdb". Instead read: Connecting to MySQL Using Connector/Python

This will help for sure -

arr=['a','b','h','i']     # let this be the list
s=""                      # creating a empty string
for i in arr:
   s+=i                   # to form string without using any function
print(s) 


       

You can create render the results (payments) and use a fancy way to iterate over items instead of adding a for loop.

const noGuest = 3;_x000D_
_x000D_
Array(noGuest).fill(noGuest).map(guest => {_x000D_
  console.log(guest);_x000D_
});

Example:

renderPayments(noGuest) {
  return Array(noGuest).fill(noGuest).map((guess, index) => {
    return(
      <View key={index}>
        <View><TextInput /></View>
        <View><TextInput /></View>
        <View><TextInput /></View>
      </View>
    );
  }
}

Then use it where you want it

render() {
  return(
     const { guest } = this.state;
     ...
     {this.renderPayments(guest)}
  );
}

Hope you got the idea.

If you want to understand this in simple Javascript check Array.prototype.fill()

Sending an HTTP POST request using file_get_contents is not that hard, actually : as you guessed, you have to use the $context parameter.

There's an example given in the PHP manual, at this page : HTTP context options (quoting) :

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-Type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

Basically, you have to create a stream, with the right options (there is a full list on that page), and use it as the third parameter to file_get_contents -- nothing more ;-)

As a sidenote : generally speaking, to send HTTP POST requests, we tend to use curl, which provides a lot of options an all -- but streams are one of the nice things of PHP that nobody knows about... too bad...

You can use

    nditer

Here I calculated no. of positive and negative coefficients in a logistic regression:

b=sentiment_model.coef_
pos_coef=0
neg_coef=0
for i in np.nditer(b):
    if i>0:
    pos_coef=pos_coef+1
    else:
    neg_coef=neg_coef+1
print("no. of positive coefficients is : {}".format(pos_coef))
print("no. of negative coefficients is : {}".format(neg_coef))

Output:

no. of positive coefficients is : 85035
no. of negative coefficients is : 36199

This is really weird, why nobody is mentioning the /IM switch ?! I've been using it for a long time in backup jobs. But I tried googling just now and I couldn't land on a single web page that says anything about it even on MS website !!! Also found so many user posts complaining about the same issue!!

Anyway.. to use Robocopy to overwrite EVERYTHING what ever size or time in source or distination you must include these three switches in your command (/IS /IT /IM)

/IS :: Include Same files. (Includes same size files)
/IT :: Include Tweaked files. (Includes same files with different Attributes)
/IM :: Include Modified files (Includes same files with different times).

This is the exact command I use to transfer few TeraBytes of mostly 1GB+ files (ISOs - Disk Images - 4K Videos):

robocopy B:\Source D:\Destination /E /J /COPYALL /MT:1 /DCOPY:DATE /IS /IT /IM /X /V /NP /LOG:A:\ROBOCOPY.LOG

I did a small test for you .. and here is the result:

Dest, Disk: WD Gold 6TB (Compare the write speed with my result)

Even with those "Extras", that's for reporting only because of the "/X" switch. As you can see nothing was Skipped and Total number and size of all files are equal to the Copied. Sometimes It will show small number of skipped files when I abuse it and cancel it multiple times during operation but even with that the values in the first 2 columns are always Equal. I also confirmed that once before by running a PowerShell script that scans all files in destination and generate a report of all time-stamps.

Some performance tips from my history with it and so many tests & troubles!:

. Despite of what most users online advise to use maximum threads "/MT:128" like it's a general trick to get the best performance ... PLEASE DON'T USE "/MT:128" WITH VERY LARGE FILES ... that's a big mistake and it will decrease your drive performance dramatically after several runs .. it will create very high fragmentation or even cause the files system to fail in some cases and you end up spending valuable time trying to recover a RAW partition and all that nonsense. And above all that, It will perform 4-6 times slower!!

For very large files:

1. Use Only "One" thread "/MT:1" | Impact: BIG
2. Must use "/J" to disable buffering. | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: Medium.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: Low.

For regular big files:

1. Use multi threads, I would not exceed "/MT:4" | Impact: BIG
2. IF destination disk has low Cache specs use "/J" to disable buffering | Impact: High
3. & 4 same as above.

For thousands of tiny files:

1. Go nuts :) with Multi threads, at first I would start with 16 and multibly by 2 while monitoring the disk performance. Once it starts dropping I'll fall back to the prevouse value and stik with it | Impact: BIG
2. Don't use "/J" | Impact: High
3. Use "/NP" with "/LOG:file" and Don't output to the console by "/TEE" | Impact: HIGH.
4. Put the "/LOG:file" on a separate drive from the source or destination | Impact: HIGH.

Quick guide to setup a cron job

Create a new text file, example: mycronjobs.txt

For each daily job (00:00, 03:45), save the schedule lines in mycronjobs.txt

00 00 * * * ruby path/to/your/script.rb
45 03 * * * path/to/your/script2.sh

Send the jobs to cron (everytime you run this, cron deletes what has been stored and updates with the new information in mycronjobs.txt)

crontab mycronjobs.txt

Extra Useful Information

See current cron jobs

crontab -l

Remove all cron jobs

crontab -r

This is how I did for my CRUDManager class initialized in Angular controller, which later passed over to jQuery button-click event defined outside the controller:

In Angular Controller:

        // Note that I can even pass over the $scope to my CRUDManager's constructor.
        var crudManager = new CRUDManager($scope, contextData, opMode);

        crudManager.initialize()
            .then(() => {
                crudManager.dataBind();
                $scope.crudManager = crudManager;
                $scope.$apply();
            })
            .catch(error => {
                alert(error);
            });

In jQuery Save button click event outside the controller:

    $(document).on("click", "#ElementWithNgControllerDefined #btnSave", function () {
        var ngScope = angular.element($("#ElementWithNgControllerDefined")).scope();
        var crudManager = ngScope.crudManager;
        crudManager.saveData()
            .then(finalData => {
               alert("Successfully saved!");
            })
            .catch(error => {
               alert("Failed to save.");
            });
    });

This is particularly important and useful when your jQuery events need to be placed OUTSIDE OF CONTROLLER in order to prevent it from firing twice.

You receive this error because in C language you are not allowed to use initializers with variable length arrays. The error message you are getting basically says it all.

6.7.8 Initialization

...

3 The type of the entity to be initialized shall be an array of unknown size or an object type that is not a variable length array type.

In Vue2, use v-bind.

Say I have an object for a poll

  <div class="options" v-for="option in poll.body.options">
    <div class="poll-item">
      <label v-bind:for="option._id" v-bind:style="{color: option.color}">{{option.text}}</label>
      <input type="radio" v-model="picked" v-bind:value="option._id" v-bind:id="option._id">
  </div>
  </div>

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

I have occurred the same error look following example-

async.waterfall([function(waterCB) {
    waterCB(null);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

In the above waterfall function, I am accepting inputArray parameter in waterfall 2nd function. But this inputArray not passed in waterfall 1st function in waterCB.

Cheak your function parameters Below are a correct example.

async.waterfall([function(waterCB) {
    waterCB(null, **inputArray**);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

Thanks

The most important concept to remember about the checked attribute is that it does not correspond to the checked property. The attribute actually corresponds to the defaultChecked property and should be used only to set the initial value of the checkbox. The checked attribute value does not change with the state of the checkbox, while the checked property does. Therefore, the cross-browser-compatible way to determine if a checkbox is checked is to use the property

All below methods are possible

elem.checked 

$(elem).prop("checked") 

$(elem).is(":checked") 

Do not load the javascript inside the cdn link script tag.Use a separate script tag for loading the AngularJs scripts. I had the same issue but I created a separate <script> Then the error gone.

Hat matching may be considered "broken" because it wont update ^0.1.2 to 0.2.0. When the software is emerging use 0.x.y versions and hat matching will only match the last varying digit (y). This is done on purpose. The reason is that while the software is evolving the API changes rapidly: one day you have these methods and the other day you have those methods and the old ones are gone. If you don't want to break the code for people who already are using your library you go and increment the major version: e.g. 1.0.0 -> 2.0.0 -> 3.0.0. So, by the time your software is finally 100% done and full-featured it will be like version 11.0.0 and that doesn't look very meaningful, and actually looks confusing. If you were, on the other hand, using 0.1.x -> 0.2.x -> 0.3.x versions then by the time the software is finally 100% done and full-featured it is released as version 1.0.0 and it means "This release is a long-term service one, you can proceed and use this version of the library in your production code, and the author won't change everything tomorrow, or next month, and he won't abandon the package".

The rule is: use 0.x.y versioning when your software hasn't yet matured and release it with incrementing the middle digit when your public API changes (therefore people having ^0.1.0 won't get 0.2.0 update and it won't break their code). Then, when the software matures, release it under 1.0.0 and increment the leftmost digit each time your public API changes (therefore people having ^1.0.0 won't get 2.0.0 update and it won't break their code).

Given a version number MAJOR.MINOR.PATCH, increment the:

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards-compatible manner, and
PATCH version when you make backwards-compatible bug fixes.

Just use:

Focus.of(context).unfocus();

new String(byteArray, 0, bytesRead); does not modify the array. You need to use System.arrayCopy to trim the array to the actual data size. Otherwise you are processing all 102400 bytes most of which are zeros.

You need the actual package (the directory containing __init__.py) stored somewhere that's in your system's PYTHONPATH. Normally, packages are distributed with a directory above the package directory, containing setup.py (which you should use to install the package), documentation, etc. This directory is not a package. Additionally, your Python27 directory is probably not in PYTHONPATH; more likely one or more subdirectories of it are.

Use toString when you need to display the name to the user.

Use name when you need the name for your program itself, e.g. to identify and differentiate between different enum values.

As everyone said above

var str = "foo"
str += " bar"
console.log(str) //will now give you "foo bar"

If anyone's still stuck on this, the easiest solution I found was to "Retarget Solution". In my case, the project was built of SDK 8.1, upgrading to VS2017 brought with it SDK 10.0.xxx.

To retarget solution: Project->Retarget Solution->"Select whichever SDK you have installed"->OK

From there on you can simply build/debug your solution. Hope it helps

I was working with talend V7.3.1 and I had poi version "4.1.0" and including xml-beans from the list of dependencies didnt fix my problem (i.e: 2.3.0 and 2.6.0).

It was fixed by downloading the jar "xmlbeans-3.0.1.jar" and adding it to the project

If you are creating a class that extends an Adapter, you can use parent variable to obtain the context.

public class MyAdapter extends ArrayAdapter<String> {
private Context context;
   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
       context = parent.getContext();
       context.getResources().getColor(R.color.red);
       return convertView;
   }
}

You can do the same with RecyclerView.Adapter, but instead of getview() you will use onCreateViewHolder().

Old question but I had similar issue and I solved it by adding

extern void* memset(void*, int, size_t);

or just

extern void* memset();

at the top of translation unit ( *.c file ).

For me its now :

docker restart $(docker ps -a -q)

Some time you miss below line. add this router will understand this.

module.exports = router;

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

Have you tried this?

$('.myClass, .myOtherClass').removeClass('theclass');

I created a Eclipse plugin, which can count the lines of source code. It support Kotlin, Java, Java Script, JSP, XML, C/C++, C#, and many other file types.

Please take a look at it. Any feedback would be appreciated!

It is not possible to return an array from a C++ function. 8.3.5[dcl.fct]/6:

Functions shall not have a return type of type array or function[...]

Most commonly chosen alternatives are to return a value of class type where that class contains an array, e.g.

struct ArrayHolder
{
    int array[10];
};

ArrayHolder test();

Or to return a pointer to the first element of a statically or dynamically allocated array, the documentation must indicate to the user whether he needs to (and if so how he should) deallocate the array that the returned pointer points to.

E.g.

int* test2()
{
    return new int[10];
}

int* test3()
{
    static int array[10];
    return array;
}

While it is possible to return a reference or a pointer to an array, it's exceedingly rare as it is a more complex syntax with no practical advantage over any of the above methods.

int (&test4())[10]
{
        static int array[10];
        return array;
}

int (*test5())[10]
{
        static int array[10];
        return &array;
}

You are doing a cartesian join. This means that if you wouldn't have even have the single where clause, the number of results you get would be book_customer size times books size times book_order size times publisher size.

In order words, the result set gets blown up because you didn't add meaningful join clauses. Your correct query should look something like this:

SELECT bc.firstname, bc.lastname, b.title, TO_CHAR(bo.orderdate, 'MM/DD/YYYY') "Order Date", p.publishername
FROM book_customer bc, books b, book_order bo, publisher p
WHERE bc.book_id = b.book_id
AND bo.book_id = b.book_id
(etc.)
AND publishername = 'PRINTING IS US';

Note: usually it is adviced to not use the implicit joins like in this query, but use the INNER JOIN syntax. I am assuming however, that this syntax is used in your study material so I've left it in.

You can also try this.

 select db_name(dbid) dbname, filename from sys.sysaltfiles

Yes, there is a possibility of stack overflow. The C and C++ standard do not dictate things like stack depth, those are generally an environmental issue.

Most decent development environments and/or operating systems will let you tailor the stack size of a process, either at link or load time.

You should specify which OS and development environment you're using for more targeted assistance.

For example, under Ubuntu Karmic Koala, the default for gcc is 2M reserved and 4K committed but this can be changed when you link the program. Use the --stack option of ld to do that.

Small update on Marc we will have additional " , " at the end. i used stuff function to remove extra semicolon .

       SELECT STUFF((  SELECT ',' + ModuleValue AS ModuleValue
                           FROM ModuleValue WHERE ModuleID=@ModuleID
                      FOR XML PATH('') 
                     ), 1, 1, '' )

Another way this might fail is if the account running the service doesn't have write permission into the data directory.

In that case the service will be unable to create a lock file.

The mongod service behaves badly in this situation and goes into a loop starting a process, which immediately throws an unhandled exception, crashes, etc. the log file gets recreated every time the process starts up, so you have to grab it quick if you want to see the error.

the default user for windows services would be localhost\system. so the fix is to ensure this user can write into your db directory, or start the service as another user who can.

You can use the System.Diagnostics.Debug.Write or System.Runtime.InteropServices method to write messages to the Output Window.

the image has a property named Style ( like most of the react-native Compponents) and for Image's Styles, there is a property named resizeMode that takes values like: contain,cover,stretch,center,repeat

most of the time if you use center it will work for you

foreach($shipmentarr as $index=>$val){    
    $additionalService = array();

    foreach($additionalService[$index] as $key => $value) {

        array_push($additionalService,$value);

    }
}

Well, you can just sort the files first, and diff the sorted files.

sort file1 > file1.sorted
sort file2 > file2.sorted
diff file1.sorted file2.sorted

You can also filter the output to report lines in file2 which are absent from file1:

diff -u file1.sorted file2.sorted | grep "^+" 

As indicated in comments, you in fact do not need to sort the files. Instead, you can use a process substitution and say:

diff <(sort file1) <(sort file2)

For a script working with Python 2 (tested versions 2.7.3 and 2.6.8) and Python 3 (3.2.3 and 3.3.2+) try:

#! /usr/bin/env python

try:
    # For Python 3.0 and later
    from urllib.request import urlopen
except ImportError:
    # Fall back to Python 2's urllib2
    from urllib2 import urlopen

html = urlopen("http://www.google.com/")
print(html.read())

If you want to update your project using SVN then first of all:

1. Go to the path on which your project is stored through command prompt.

2. Use the command SVN update

That's it.

you can use this:

try {
                Intent followIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href=" +
                        "https://www.facebook.com/app_scoped_user_id/"+scoped user id+"/"));
                activity.startActivity(followIntent);
            } catch (Exception e) {
                activity.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + user name)));
                String errorMessage = (e.getMessage() == null) ? "Message is empty" : e.getMessage();
            }

attention: you can get scoped user id from "link" permission facebook api

Flatmap and Map both transforms the collection.

Difference:

map(func)
Return a new distributed dataset formed by passing each element of the source through a function func.

flatMap(func)
Similar to map, but each input item can be mapped to 0 or more output items (so func should return a Seq rather than a single item).

The transformation function:
map: One element in -> one element out.
flatMap: One element in -> 0 or more elements out (a collection).

Yes, this can be done via javascript feature detection ( or browser detection , e.g. Modernizr ) . Then, use yepnope.js to load required resources ( JS and/or CSS )

1. Open Terminal
2. Write or paste in: defaults write org.R-project.R force.LANG en_US.UTF-8
3. Close Terminal (including any RStudio window)
4. Start R

For someone runs R in a docker environment (under root), try to run R with below command,

LC_ALL=C.UTF-8 R
# instead of just `R`
