Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

_{http://www.msfn.org/board/topic/113128-connect-to-vpn-from-cmdexe-vista/?p=747265}

Yes, you can do

git push https://username:[email protected]/file.git --all

in this case https://username:[email protected]/file.git replace the origin in git push origin --all

To see more options for git push, try git help push

I went with the HTML5 local storage solution... All my links call a function which sets this before changing window.location:

localStorage.topper = document.body.scrollTop;

and each page has this in the body's onLoad:

  if(localStorage.topper > 0){ 
    window.scrollTo(0,localStorage.topper);
  }

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

The values of form elements including type='hidden' are submitted to the server when the form is posted. input type="hidden" values are not visible in the page. Maintaining User IDs in hidden fields, for example, is one of the many uses.

SO uses a hidden field for the upvote click.

<input value="16293741" name="postId" type="hidden">

Using this value, the server-side script can store the upvote.

You can use jQuery UI and do something like this

Html:

<button id="callConfirm">Confirm!</button>

<div id="dialog" title="Confirmation Required">
  Are you sure about this?
</div>?

Javascript:

$("#dialog").dialog({
   autoOpen: false,
   modal: true,
   buttons : {
        "Confirm" : function() {
            alert("You have confirmed!");            
        },
        "Cancel" : function() {
          $(this).dialog("close");
        }
      }
    });

$("#callConfirm").on("click", function(e) {
    e.preventDefault();
    $("#dialog").dialog("open");
});

?

You should check that fractional part of the number is 0. Use

x==Math.ceil(x)

or

x==Math.round(x)

or something like that

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

foreach ($array as $k => $v) {
  $tArray[$k] = $v['Weight'];
}
$min_value = min($tArray);
$max_value = max($tArray);

This is my utils service:

angular.module('myApp', []).service('Utils', function Utils($timeout) {
    var Super = this;

    this.doWhenReady = function(scope, callback, args) {
        if(!scope.$$phase) {
            if (args instanceof Array)
                callback.apply(scope, Array.prototype.slice.call(args))
            else
                callback();
        }
        else {
            $timeout(function() {
                Super.doWhenReady(scope, callback, args);
            }, 250);
        }
    };
});

and this is an example for it's usage:

angular.module('myApp').controller('MyCtrl', function ($scope, Utils) {
    $scope.foo = function() {
        // some code here . . .
    };

    Utils.doWhenReady($scope, $scope.foo);

    $scope.fooWithParams = function(p1, p2) {
        // some code here . . .
    };

    Utils.doWhenReady($scope, $scope.fooWithParams, ['value1', 'value2']);
};

You only need to include user_agent.php file which can be found from Mobile device detection in PHP page and use the following code.

<?php
//include file
include_once 'user_agent.php';

//create an instance of UserAgent class
$ua = new UserAgent();

//if site is accessed from mobile, then redirect to the mobile site.
if($ua->is_mobile()){
   header("Location:http://m.codexworld.com");
   exit;
}
?>

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

$('#yourid').prop('disabled', true);

First of all, swapping without a temporary variable in a language as C# is a very bad idea.

But for the sake of answer, you can use this code:

startAngle = startAngle + stopAngle;
stopAngle = startAngle - stopAngle;
startAngle = startAngle - stopAngle;

Problems can however occur with rounding off if the two numbers differ largely. This is due to the nature of floating point numbers.

If you want to hide the temporary variable, you can use a utility method:

public static class Foo {

    public static void Swap<T> (ref T lhs, ref T rhs) {
        T temp = lhs;
        lhs = rhs;
        rhs = temp;
    }
}

Other answers sort of hint at it, but the problem may arise from expecting a bytes object. In Python 3, decode is valid when you have an object of class bytes. Running encode before decode may "fix" the problem, but it is a useless pair of operations that suggest the problem us upstream.

depends on the isolation level of the incomming transaction.

Sql transaction isolation explained

Create a file called "search_files.bat" and place the contents below into the file. Then double click it. The temporary %THH% variable was put in place to handle the AM appropriately. If there is a 0 in the first 2 digits of the time, Windows ignores the rest of the file name of the LOG file.

CD .
SET THH=%time:~0,2%
SET THH=%THH: =0%
dir /s /b *.* > %date:~10,4%-%date:~4,2%-%date:~7,2%@%THH%.%time:~3,2%.%time:~6,2%.LOG

Use mktime():

<?php
 $monthNum = 5;
 $monthName = date("F", mktime(0, 0, 0, $monthNum, 10));
 echo $monthName; // Output: May
?>

See the PHP manual : http://php.net/mktime

Most of bootstrap datepickers as I write this answer are rather buggy when included in Bootstrap 4. In my view the least code adding solution is a jQuery plugin. I used this one https://plugins.jquery.com/datetimepicker/ - you can see its usage here: https://xdsoft.net/jqplugins/datetimepicker/ It sure is not as smooth as the whole BS interface, but it only requires its css and js files along with jQuery which is already included in bootstrap.

This guide was helpful for me http://wiki.eclipse.org/EGit/User_Guide#Resolving_a_merge_conflict.

UPDATED Just a note on that about my procedure, this is how I proceed:

1. Commit My change
2. Fetch (Syncrhonize workspace)
3. Pull
4. Manage Conflicts with Merge Tool (Team->Merge Tool) and Save
5. Add each file to stage (Team -> Add to index)
6. Now the Commit Message in the Stage window is prefilled with "Merged XXX". You can leave as it is or change the commit message
7. Commit and Push

It is dangerous in some cases but it is very usefull to avoid to use external tool like Git Extension or Source Tree

As far as best practices, keep an eye for recursive functions. In my case I ran into issues with recursion (where there didn't need to be). A simplified example of what I was doing:

def my_function():
    # lots of memory intensive operations
    # like operating on images or huge dictionaries and lists
    .....
    my_flag = True
    if my_flag:  # restart the function if a certain flag is true
        my_function()

def main():
    my_function()

operating in this recursive manner won't trigger the garbage collection and clear out the remains of the function, so every time through memory usage is growing and growing.

My solution was to pull the recursive call out of my_function() and have main() handle when to call it again. this way the function ends naturally and cleans up after itself.

def my_function():
    # lots of memory intensive operations
    # like operating on images or huge dictionaries and lists
    .....
    my_flag = True
    .....
    return my_flag

def main():
    result = my_function()
    if result:
        my_function()

Simplest C/C++ any compiler/standard compliant solution, was mentioned by @leftaroundabout in comments above:

int x = *(int*)"abcd";

Or a bit more specific:

int x = *(int32_t*)"abcd";

One more solution, also compliant with C/C++ compiler/standard since C99 (except clang++, which has a known bug):

int x = ((union {char s[5]; int number;}){"abcd"}).number;

/* just a demo check: */
printf("x=%d stored %s byte first\n", x, x==0x61626364 ? "MSB":"LSB");

Here anonymous union is used to give a nice symbol-name to the desired numeric result, "abcd" string is used to initialize the lvalue of compound literal (C99).

JButton b3 = new JButton("CLOSE");

b3.setBounds(50, 375, 250, 50);

b3.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)

        System.exit(0);
    }
});

Step 1:

The object locator supposed to be used here is XPath. So derive the XPath for those two checkboxes.

String housingmoves="//label[contains(text(),'housingmoves')]/preceding-sibling::input";
String season_country_homes="//label[contains(text(),'Seaside & Country Homes')]/preceding-sibling::input";

Step 2:

Perform a click on the checkboxes

driver.findElement(By.xpath(housingmoves)).click();
driver.findElement(By.xpath(season_country_homes)).click();

The simplest way today would be to simply request the Material Icons font from Google Fonts, for example in your HTML header tag:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

or in your stylesheet:

@import url(https://fonts.googleapis.com/icon?family=Material+Icons);

and then use as font icon with ligatures as explained in the md-icon directive. For example:

<md-icon aria-label="Menu" class="material-icons">menu</md-icon>

The complete list of icons/ligatures is at https://www.google.com/design/icons/

I'm currently using two GCM Project Id in the same app package. I put the google-service.json of my first GCM project but I switch from the first to the second one only changing the SENDER_ID:

    String token = instanceID.getToken(SENDER_ID,GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

(At this point I think that the google-services.json isn't mandatory )

There is my working solution for sending image with post, using apache http libraries (very important here is boundary add It won't work without it in my connection):

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
            byte[] imageBytes = baos.toByteArray();

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(StaticData.AMBAJE_SERVER_URL + StaticData.AMBAJE_ADD_AMBAJ_TO_GROUP);

            String boundary = "-------------" + System.currentTimeMillis();

            httpPost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);

            ByteArrayBody bab = new ByteArrayBody(imageBytes, "pic.png");
            StringBody sbOwner = new StringBody(StaticData.loggedUserId, ContentType.TEXT_PLAIN);
            StringBody sbGroup = new StringBody("group", ContentType.TEXT_PLAIN);

            HttpEntity entity = MultipartEntityBuilder.create()
                    .setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
                    .setBoundary(boundary)
                    .addPart("group", sbGroup)
                    .addPart("owner", sbOwner)
                    .addPart("image", bab)
                    .build();

            httpPost.setEntity(entity);

            try {
                HttpResponse response = httpclient.execute(httpPost);
                ...then reading response

Assuming you are using Windows forms, you could allow the user to select a row and in the delete key click event. It is recommended that you allow the user to select 1 row only and not a group of rows (myDataGridView.MultiSelect = false)

Private Sub pbtnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click

        If myDataGridView.SelectedRows.Count > 0 Then
            'you may want to add a confirmation message, and if the user confirms delete
            myDataGridView.Rows.Remove(myDataGridView.SelectedRows(0))
        Else
            MessageBox.Show("Select 1 row before you hit Delete")
        End If

    End Sub

Note that this will not delete the row form the database until you perform the delete in the database.

Why don't you consider www.cameraftp.com? it supports image upload and online viewer

It specifies an "Anchor", or a position on the page, and allows you to "jump" or "scroll" to that position on the page.

Please see this page for more details.

window.location is just what you need. Other thing you can do is to create anchor element and simulate click on it

$("<a href='your url'></a>").click(); 

To query the index information of a table, you use the SHOW INDEXES statement as follows:

 SHOW INDEXES FROM table_name;

You can specify the database name if you are not connected to any database or you want to get the index information of a table in a different database:

SHOW INDEXES FROM table_name 
IN database_name;

The following query is similar to the one above:

SHOW INDEXES FROM database_name.table_name;

Note that INDEX and KEYS are the synonyms of the INDEXES, IN is the synonym of the FROM, therefore, you can use these synonyms in the SHOW INDEXES column instead. For example:

SHOW INDEX IN table_name 
FROM database_name;

Or

 SHOW KEYS FROM tablename
 IN databasename;

Following has worked for me:

myDialog.setCanceledOnTouchOutside(true);

There are a number of times you might consider using an interface over an abstract implementation

• When the available abstract implementation doesn't do what you want and you want to create your own
• when you have an existing class (that extends from other class) and you want to implement the functionality of the interface

Generally speaking, interfaces were introduced to overcome the lack of multiple inheritancy, amongst other things

Had troubles as well. On Linux I used Ctrl+X (and Y to confirm) and then I was back on the shell ready to pull/push.

On Windows GIT Bash Ctrl+X would do nothing and found out it works quite like vi/vim. Press i to enter inline insert mode. Type the description at the very top, press esc to exit insert mode, then type :x! (now the cursor is at the bottom) and hit enter to save and exit.

If typing :q! instead, will exit the editor without saving (and commit will be aborted)

I think for pretty-printing something, it's very helpful to know its structure.

To get the structure you have to parse it. Because of this, I don't think it gets much easier than first parsing the JSON string you have and then using the pretty-printing method toString mentioned in the comments above.

Of course you can do similar with any JSON library you like.

Check for the 32/64 bit you trying to install. both python interpreter and your app which trying to use python might be of different bit.

I would go with a simple regex which will check that days doesn't have more than 31 days and months no more than 12. Something like:

(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-((18|19|20|21)\\d\\d)

This is the format "dd-MM-yyyy". You can tweak it to your needs (for example take off the ? to make the leading 0 required - now its optional), and then use a custom logic to cut down to the specific rules like leap years February number of days case, and other months number of days cases. See the DateChecker code below.

I am choosing this approach since I tested that this is the best one when performance is taken into account. I checked this (1st) approach versus 2nd approach of validating a date against a regex that takes care of the other use cases, and 3rd approach of using the same simple regex above in combination with SimpleDateFormat.parse(date).
The 1st approach was 4 times faster than the 2nd approach, and 8 times faster than the 3rd approach. See the self contained date checker and performance tester main class at the bottom. One thing that I left unchecked is the joda time approach(s). (The more efficient date/time library).

Date checker code:

class DateChecker {

    private Matcher matcher;
    private Pattern pattern;

    public DateChecker(String regex) {
        pattern = Pattern.compile(regex);
    }

    /**
     * Checks if the date format is a valid.
     * Uses the regex pattern to match the date first. 
     * Than additionally checks are performed on the boundaries of the days taken the month into account (leap years are covered).
     * 
     * @param date the date that needs to be checked.
     * @return if the date is of an valid format or not.
     */
    public boolean check(final String date) {
        matcher = pattern.matcher(date);
        if (matcher.matches()) {
            matcher.reset();
            if (matcher.find()) {
                int day = Integer.parseInt(matcher.group(1));
                int month = Integer.parseInt(matcher.group(2));
                int year = Integer.parseInt(matcher.group(3));

                switch (month) {

                        //its a leap year
                        return day < 30;
                    } else {
                        return day < 29;

Some useful notes:
- to enable the assertions (assert checks) you need to use -ea argument when running the tester. (In eclipse this is done by editing the Run/Debug configuration -> Arguments tab -> VM Arguments -> insert "-ea"
- the regex above is bounded to years 1800 to 2199
- you don't need to use ^ at the beginning and $ at the end to match only the whole date string. The String.matches takes care of that.
- make sure u check the valid and invalid cases and change them according the rules that you have.
- the "only whole string" version of each regex gives the same speed as the "normal" version (the one without ^ and $). If you see performance differences this is because java "gets used" to processing the same instructions so the time lowers. If you switch the lines where the "normal" and the "only whole string" version execute, you will see this proven.

Hope this helps someone!

The only problem could be if one day

map[key] = value

will transform to -

map[key]++;

and that will cause a KeyNotFoundException.

http://www.quirksmode.org/js/cookies.html

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}

This works fine

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

You can use the ElementAt extension method on the list.

For example:

// Get the first item from the list

using System.Linq;

var myList = new List<string>{ "Yes", "No", "Maybe"};
var firstItem = myList.ElementAt(0);

// Do something with firstItem

vehicle[] car = new vehicle[N];

To sum it up,in object oriented programming, everything is modeled into classes and objects. Classes contain properties and methods. Public, private and protected keywords are used to specify access to these members(properties and methods) of a class from other classes or other .dlls or even other applications.

$startTime = strtotime('2010-05-01');

$endTime = strtotime('2010-05-10'); 

// Loop between timestamps, 1 day at a time 
do {
   $startTime = strtotime('+1 day',$startTime); 
   echo $startTime;
} while ($startTime < $endTime);

You don't need to write a program to do this in Linux. Just pipe the serial port through netcat:

netcat www.example.com port </dev/ttyS0 >/dev/ttyS0

Just replace the address and port information. Also, you may be using a different serial port (i.e. change the /dev/ttyS0 part). You can use the stty or setserial commands to change the parameters of the serial port (baud rate, parity, stop bits, etc.).

On Android 5.0+

I would recommend Apache HttpComponents HttpClient, a successor of Commons HttpClient

I would also recommend to take a look at HtmlUnit. HtmlUnit is a "GUI-Less browser for Java programs". http://htmlunit.sourceforge.net/

If you're posting a json body, dont use the form parameter. Using form will make the arrays into field[0].attribute, field[1].attribute etc. Instead use body like so.

var jsonDataObj = {'mes': 'hey dude', 'yo': ['im here', 'and here']};
request.post({
    url: 'https://api.site.com',
    body: jsonDataObj,
    json: true
  }, function(error, response, body){
  console.log(body);
});

I like Rushyo's suggestion of using AT, but this is another option:

whoami /groups | findstr /b BUILTIN\Administrators | findstr /c:"Enabled group" && goto :isadministrator

This approach would also allow you to distinguish between a non-administrator and a non-elevated administrator if you wanted to. Non-elevated administrators still have BUILTIN\Administrators in the group list but it is not enabled.

However, this will not work on some non-English language systems. Instead, try

whoami /groups | findstr /c:" S-1-5-32-544 " | findstr /c:" Enabled group" && goto :isadministrator

(This should work on Windows 7 but I'm not sure about earlier versions.)

Don't know what parameter should I use?

A lot of Developers including have hard time at the beginning writing an AsyncTask because of the ambiguity of the parameters. The big reason is we try to memorize the parameters used in the AsyncTask. The key is Don't memorize. If you can visualize what your task really needs to do then writing the AsyncTask with the correct signature would be a piece of cake.

What is an AsyncTask?

AsyncTask are background task which run in the background thread. It takes an Input, performs Progress and gives Output.

ie AsyncTask<Input,Progress,Output>

Just figure out what your Input, Progress and Output are and you will be good to go.

For example

How does doInbackground() changes with AsyncTask parameters?

How doInBackground() and onPostExecute(),onProgressUpdate() are related?

How can You write this in a code?

 DownloadTask extends AsyncTask<String,Integer,String>{

    @Override
    public void onPreExecute(){
    }

    @Override
    public String doInbackGround(String... params)
    {
         // Download code
         int downloadPerc = // calculate that
         publish(downloadPerc);

         return "Download Success";
    }

    @Override
    public void onPostExecute(String result)
    {
         super.onPostExecute(result);
    }

    @Override
    public void onProgressUpdate(Integer... params)
    {
         // show in spinner, access UI elements
    }

}

How will you run this Task in Your Activity?

new DownLoadTask().execute("Paradise.mp3");

Go to Android SDK Manager and install the latest version of below two libraries

1. Google Play Services
2. Google Repository

I agree with pjco. The best way is the official method explained in Support Library Setup in the tutorial at developer.android.com.

Then, in the Eclipse "package explorer", expand your main project and delete android-support-v4.jar from the "libs" folder (as Pratik Butani suggested).

This worked for me.

None of these answers worked for me, so I uninstalled Android Studio, and reinstalled it. (I did not delete settings) It now works perfectly.

Client side For disabling validation for a form, multiple options based on my research is given below. One of them would would hopefully work for you.

Option 1

I prefer this, and this works perfectly for me.

(function ($) {
    $.fn.turnOffValidation = function (form) {
        var settings = form.validate().settings;

        for (var ruleIndex in settings.rules) {
            delete settings.rules[ruleIndex];
        }
    };
})(jQuery); 

and invoking it like

$('#btn').click(function () {
    $(this).turnOffValidation(jQuery('#myForm'));
});

Option 2

$('your selector here').data('val', false);
$("form").removeData("validator");
$("form").removeData("unobtrusiveValidation");
$.validator.unobtrusive.parse("form");

Option 3

var settings = $.data($('#myForm').get(0), 'validator').settings;
settings.ignore = ".input";

Option 4

 $("form").get(0).submit();
 jQuery('#createForm').unbind('submit').submit();

Option 5

$('input selector').each(function () {
    $(this).rules('remove');
});

Server Side

Create an attribute and mark your action method with that attribute. Customize this to adapt to your specific needs.

[AttributeUsage(AttributeTargets.All)]
public class IgnoreValidationAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var modelState = filterContext.Controller.ViewData.ModelState;

        foreach (var modelValue in modelState.Values)
        {
            modelValue.Errors.Clear();
        }
    }
}

A better approach has been described here Enable/Disable mvc server side validation dynamically

A user in an Oracle database only has the privileges you grant. So you can create a read-only user by simply not granting any other privileges.

When you create a user

CREATE USER ro_user
 IDENTIFIED BY ro_user
 DEFAULT TABLESPACE users
 TEMPORARY TABLESPACE temp;

the user doesn't even have permission to log in to the database. You can grant that

GRANT CREATE SESSION to ro_user

and then you can go about granting whatever read privileges you want. For example, if you want RO_USER to be able to query SCHEMA_NAME.TABLE_NAME, you would do something like

GRANT SELECT ON schema_name.table_name TO ro_user

Generally, you're better off creating a role, however, and granting the object privileges to the role so that you can then grant the role to different users. Something like

Create the role

CREATE ROLE ro_role;

Grant the role SELECT access on every table in a particular schema

BEGIN
  FOR x IN (SELECT * FROM dba_tables WHERE owner='SCHEMA_NAME')
  LOOP
    EXECUTE IMMEDIATE 'GRANT SELECT ON schema_name.' || x.table_name || 
                                  ' TO ro_role';
  END LOOP;
END;

And then grant the role to the user

GRANT ro_role TO ro_user;

As already mentioned, the only way is to use a plugin that replaces <select> functionality.

A list of jQuery plugins: http://plugins.jquery.com/tag/select/

Take a look at the example using Select2 plugin: http://jsfiddle.net/swsLokfj/23/

# or even faster copy paste answer if you have sudo on the host 
sudo su - postgres  -c "psql template1 -c 'CREATE EXTENSION IF NOT EXISTS \"dblink\";'"

Keep track of your index: That's how it is done in Java:

 int index = 0;
    for (Element song: question){
        // Do whatever
         index++;
    }

docker system prune -a

(You'll be asked to confirm the command. Use -f to force run, if you know what you're doing.)

All the timers have the equivalent of Start() and Stop() methods, except System.Threading.Timer.

So an extension method such as...

public static void Reset(this Timer timer)
{
  timer.Stop();
  timer.Start();
}

...is one way to go about it.

Use newDirName = os.path.abspath(dir) to create a full directory path name for the subdirectory and then list its contents as you have done with the parent (i.e. newDirList = os.listDir(newDirName))

You can create a separate method of your code snippet and call it recursively through the subdirectory structure. The first parameter is the directory pathname. This will change for each subdirectory.

This answer is based on the 3.1.1 version documentation of the Python Library. There is a good model example of this in action on page 228 of the Python 3.1.1 Library Reference (Chapter 10 - File and Directory Access). Good Luck!

Print the full file name out or step through in a debugger. When I get confused by errors like this, it means that my assumptions and expectations don't match reality. Make sure you can see what the path is; it'll help you figure out where you've gone wrong.

How would you like to differentiate between forms? You can use different IDs, and then use this function:

function getInputElements(formId) {
    var form = document.getElementById(formId);
    if (form === null) {
        return null;
    }
    return form.getElementsByTagName('input');
}

You can list down the entries (certificates details) with the keytool and even you don't need to mention the store type.

keytool -list -v -keystore cert.p12 -storepass <password>

 Keystore type: PKCS12
 Keystore provider: SunJSSE

 Your keystore contains 1 entry
 Alias name: 1
 Creation date: Jul 11, 2020
 Entry type: PrivateKeyEntry
 Certificate chain length: 2

This method can be helpful.

def avg(arr)
  val = 0.0

  arr.each do |n|
    val += n
  end

  len = arr.length

  val / len 
end

p avg([0,4,8,2,5,0,2,6])

Another approach, if the struct allows it, is to use a #define with the default values inside:

#define MYSTRUCT_INIT { 0, 0, true }

typedef struct
{
    int id;
    int flag;
    bool foo;
} MyStruct;

Use:

MyStruct val = MYSTRUCT_INIT;

There's also solution for Node JS app. CORS Anywhere is a NodeJS proxy which adds CORS headers to the proxied request.

The url to proxy is literally taken from the path, validated and proxied. The protocol part of the proxied URI is optional, and defaults to "http". If port 443 is specified, the protocol defaults to "https".

This package does not put any restrictions on the http methods or headers, except for cookies. Requesting user credentials is disallowed. The app can be configured to require a header for proxying a request, for example to avoid a direct visit from the browser. https://robwu.nl/cors-anywhere.html

I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']

And let's say you want to include products made before 2014. You could write,

df[df['Year'] < 2014]

To return all the rows where this is the case. You can add different conditions.

df[df['Year'] < 2014][df['Color' == 'Red']

Then just choose the columns you want as directed above. For instance, the product color and key for the df above,

df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

Something like this might be the easiest way.

<a href="mailto:?subject=I wanted you to see this site&amp;body=Check out this site http://www.website.com."
   title="Share by Email">
  <img src="http://png-2.findicons.com/files/icons/573/must_have/48/mail.png">
</a>

You could find another email image and add that if you wanted.

You can define a Range, the size of your array and use it's value property:

Sub PrintArray(Data, SheetName As String, intStartRow As Integer, intStartCol As Integer)

    Dim oWorksheet As Worksheet
    Dim rngCopyTo As Range
    Set oWorksheet = ActiveWorkbook.Worksheets(SheetName)

    ' size of array
    Dim intEndRow As Integer
    Dim intEndCol As Integer
    intEndRow = UBound(Data, 1)
    intEndCol = UBound(Data, 2)

    Set rngCopyTo = oWorksheet.Range(oWorksheet.Cells(intStartRow, intStartCol), oWorksheet.Cells(intEndRow, intEndCol))
    rngCopyTo.Value = Data

End Sub

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:contentDescription="@string/banner_alt"
    android:src="@drawable/banner_portrait" />

Working example:

    Intent intent = new Intent(ctx, HomeActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder b = new NotificationCompat.Builder(ctx);

    b.setAutoCancel(true)
     .setDefaults(Notification.DEFAULT_ALL)
     .setWhen(System.currentTimeMillis())         
     .setSmallIcon(R.drawable.ic_launcher)
     .setTicker("Hearty365")            
     .setContentTitle("Default notification")
     .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
     .setDefaults(Notification.DEFAULT_LIGHTS| Notification.DEFAULT_SOUND)
     .setContentIntent(contentIntent)
     .setContentInfo("Info");


    NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(1, b.build());

You can do lots of stupid thing with javascript. I will leave this quote here from YDKJS book.

Mentioned page of the book ->

https://books.google.com.tr/books?id=iOc6CwAAQBAJ&pg=PT150&lpg=PT150&dq=JS+engine+cannot+statically+analyze+the+contents+of+plain+object&source=bl&ots=7v8fMUgwhx&sig=dP3BpY7mEvpvfyxO_koWaXczBWI&hl=en&sa=X&ved=2ahUKEwi4qseXyrDdAhUS-6QKHZYTAEQQ6AEwAHoECAEQAQ#v=onepage&q=JS%20engine%20cannot%20statically%20analyze%20the%20contents%20of%20plain%20object&f=false

Calendar cal = Calendar.getInstance(); //This to obtain today's date in our Calendar var.

java.sql.Date date = new Date (cal.getTimeInMillis());

You could make id a series of comma-seperated values, like this:

index.php?id=1,2,3&name=john

Then, within your PHP code, explode it into an array:

$values = explode(",", $_GET["id"]);
print count($values) . " values passed.";

This will maintain brevity. The other (more commonly used with $_POST) method is to use array-style square-brackets:

index.php?id[]=1&id[]=2&id[]=3&name=john

But that clearly would be much more verbose.

I ran into this issue when I wanted to temporarily disable the sending of an email while working on another part of the code.

Commenting the use of the service triggered a lot of cascade errors, so instead of commenting I used a condition

if false {
    // Technically, svc still be used so no yelling
    _, err = svc.SendRawEmail(input) 
    Check(err)
}

You could use a regular expression like this

If Regex.IsMatch(number, "^[0-9 ]+$") Then

...

End If

For converting date to string check this thread

Convert java.util.Date to String

And for converting string to date try this,

import java.text.ParseException;
import java.text.SimpleDateFormat;

public class StringToDate
{
    public static void main(String[] args) throws ParseException
    {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
        String strDate = "14/03/2003 08:05:10";     
        System.out.println("Date - " + sdf.parse(strDate));
    }
}

You can take advantage of the "deleted" pseudo table in this example. Something like:

begin transaction;

   declare @deletedIds table ( id int );

   delete from t1
   output deleted.id into @deletedIds
   from table1 as t1
    inner join table2 as t2
      on t2.id = t1.id
    inner join table3 as t3
      on t3.id = t2.id;

   delete from t2
   from table2 as t2
    inner join @deletedIds as d
      on d.id = t2.id;

   delete from t3
   from table3 as t3 ...

commit transaction;

Obviously you can do an 'output deleted.' on the second delete as well, if you needed something to join on for the third table.

As a side note, you can also do inserted.* on an insert statement, and both inserted.* and deleted.* on an update statement.

EDIT: Also, have you considered adding a trigger on table1 to delete from table2 + 3? You'll be inside of an implicit transaction, and will also have the "inserted." and "deleted." pseudo-tables available.

It's possible that the modules are installed, but your PHP.ini still points to an old directory.

Check the contents of /usr/lib/php/extensions. In mine, there were two directories: no-debug-non-zts-20060613 and no-debug-non-zts-20060613. Around line 428 of your php.ini, change:

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613"

to

extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20090626"

Then restart apache. This should resolve the issue.

Another alternative is HikariCP.

Here is the comparison benchmark

I give my solution for Mac:

1. With your device connected to the USB port, open a terminal and go to the adb folder.
2. Write: ./adb devices
3. The terminal will show something like this: List of devices attached 36ac5997 device
4. Take note of the serial number (36ac5997)
5. Write: ./adb -s 36ac5997 to connect to the device
6. Write: ./adb logcat

If at any time you want to clear the log, type ./adb logcat -c

You shouldn't be creating a new Random in method scope. Make it a class member:

public class Foo {
   private Random random 

   public Foo() {
       this(System.currentTimeMillis());
   }

   public Foo(long seed) {
       this.random = new Random(seed);
   }

   public synchronized double getNext() {
        return generator.nextDouble();
   }
}

This is only an example. I don't think wrapping Random this way adds any value. Put it in a class of yours that is using it.

Is there a way to set the session timeout programatically

There are basically three ways to set the session timeout value:

• by using the session-timeout in the standard web.xml file ~or~
• in the absence of this element, by getting the server's default session-timeout value (and thus configuring it at the server level) ~or~
• programmatically by using the HttpSession. setMaxInactiveInterval(int seconds) method in your Servlet or JSP.

But note that the later option sets the timeout value for the current session, this is not a global setting.

This error (and also ORA-6413: Connection not open) can also be caused by parentheses in the application executable path and a bug in the 10.2.0.1 or lower oracle client libraries.

You should either upgrade your oracle client library or change the executable path.

Try this CSS to disable resizing

The CSS to disable resizing for all textareas looks like this:

textarea {
    resize: none;
}

You could instead just assign it to a single textarea by name (where the textarea HTML is ):

textarea[name=foo] {
    resize: none;
}

Or by id (where the textarea HTML is ):

#foo {
    resize: none;
}

Taken from: http://www.electrictoolbox.com/disable-textarea-resizing-safari-chrome/

/^(?!my).*/

(?!expression) is a negative lookahead; it matches a position where expression doesn't match starting at that position.

The problem was, in the URL i wrote http://my_domain instead of https://my_domain

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll down some pixel and scroll up

For Scroll down:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("window.scrollBy(0,250)");

OR, you can do as follows:

jse.executeScript("scroll(0, 250);");

For Scroll up:

jse.executeScript("window.scrollBy(0,-250)");
OR,
jse.executeScript("scroll(0, -250);");

Scroll to the bottom of the page:

Scenario/Test steps:
1. Open a browser and navigate to TestURL
2. Scroll to the bottom of the page

Way 1: By using JavaScriptExecutor

jse.executeScript("window.scrollTo(0, document.body.scrollHeight)");

Way 2: By pressing ctrl+end

driver.findElement(By.cssSelector("body")).sendKeys(Keys.CONTROL, Keys.END);

Way 3: By using Java Robot class

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_CONTROL);

Prevent Default

Calling preventDefault() during any stage of event flow cancels the event, meaning that any default action normally taken by the implementation as a result of the event will not occur. You can use Event.

return false

return false inside a callback prevents the default behaviour. For example, in a submit event, it doesn't submit the form. return false also stops bubbling, so the parents of the element won't know the event occurred. return false is equivalent to event.preventDefault() + event.stopPropagation()

You switch to:

json_decode($response->getBody(), true)

Instead of the other comment if you want it to work exactly as before in order to get arrays instead of objects.

Yes, you have a } too many. Anyway, compressing yourself tends to result in errors.

function () {
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        document.getElementById("content").innerHTML = xmlhttp.responseText;
    }
} // <-- end function?
xmlhttp.open("GET", "data/" + id + ".html", true);
xmlhttp.send();
}

Use Closure Compiler instead.

In some systems, attempts to speed up the assembly of fully resolved '.c' files call the pre-assembly of include files "compiling header files". However, it is an optimization technique that is not necessary for actual C development.

Such a technique basically computed the include statements and kept a cache of the flattened includes. Normally the C toolchain will cut-and-paste in the included files recursively, and then pass the entire item off to the compiler. With a pre-compiled header cache, the tool chain will check to see if any of the inputs (defines, headers, etc) have changed. If not, then it will provide the already flattened text file snippets to the compiler.

Such systems were intended to speed up development; however, many such systems were quite brittle. As computers sped up, and source code management techniques changed, fewer of the header pre-compilers are actually used in the common project.

Until you actually need compilation optimization, I highly recommend you avoid pre-compiling headers.

Remember that your img is not really a DOM element but a javascript expression.

1. This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions

2. In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components

   /** @jsx React.DOM */
   
   var Hello = React.createClass({
       render: function() {
           return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
       }
   });
   
   React.renderComponent(<Hello name="World" />, document.body);
   

If you can afford working via the file data, you can do

find -mmin +14400 -delete

Default user for MySQL is "root", and server "localhost".

A quick hack I used which works well:

const monthNumber = 8;_x000D_
const yearNumber = 2018;_x000D_
const date = `${['Jan', 'Feb', 'Mar', 'Apr',_x000D_
  'May', 'Jun', 'Jul', 'Aug',_x000D_
  'Sep', 'Oct', 'Nov', 'Dec'][monthNumber - 1]_x000D_
      } ${yearNumber}`;_x000D_
_x000D_
console.log(date);

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

You can do something like this

List<Customer> cusList = new ArrayList<Customer>();

for(Object o: list){        
    cusList.add((Customer)o);

return cusList; 

Or the Java 8 way

list.stream().forEach(x->cusList.add((Customer)x))

return cuslist;

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60

If you are using jQuery, you don't have to do anything special. Handlers added via $(document).ready() don't overwrite each other, but rather execute in turn:

$(document).ready(func1)
...
$(document).ready(func2)

If you are not using jQuery, you could use addEventListener, as demonstrated by Karaxuna, plus attachEvent for IE<9.

Note that onload is not equivalent to $(document).ready() - the former waits for CSS, images... as well, while the latter waits for the DOM tree only. Modern browsers (and IE since IE9) support the DOMContentLoaded event on the document, which corresponds to the jQuery ready event, but IE<9 does not.

if(window.addEventListener){
  window.addEventListener('load', func1)
}else{
  window.attachEvent('onload', func1)
}
...
if(window.addEventListener){
  window.addEventListener('load', func2)
}else{
  window.attachEvent('onload', func2)
}

If neither option is available (for example, you are not dealing with DOM nodes), you can still do this (I am using onload as an example, but other options are available for onload):

var oldOnload1=window.onload;
window.onload=function(){
  oldOnload1 && oldOnload1();
  func1();
}
...
var oldOnload2=window.onload;
window.onload=function(){
  oldOnload2 && oldOnload2();
  func2();
}

or, to avoid polluting the global namespace (and likely encountering namespace collisions), using the import/export IIFE pattern:

window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func1();
  }
})(window.onload)
...
window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func2();
  }
})(window.onload)

In your php.ini file set your extension directory, e.g:

extension_dir = "C:/php/ext/"

You will see in you PHP folder there is an ext folder with all the dll's and extensions.

%~dp0 may be a relative path. To convert it to a full path, try something like this:

pushd %~dp0
set script_dir=%CD%
popd

just use jQuery bind method !jquery-selector!.bind('event', !fn!);

I too faced this error in two situation

1. While performing redirection from BAL layer to DAL layer I faced this exception. Inner exception says that "Object Reference error".

2. Web.Config file key does not match.

Hope this useful to solve your problem.

Try this it works

document.querySelector('[attribute="value"]')

example :

document.querySelector('[role="button"]')

The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.

What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!

I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.

So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:

import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;

//  create and initialize an object 
public static JSONObject buildObject( final SimpleEntry... entries ) { 
    JSONObject object = new JSONObject();
    for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
    return object;
}

//  nest a list of objects inside another                          
public static void putObjects( final JSONObject parentObject, final String key,
                               final JSONObject... objects ) { 
    List objectList = new ArrayList<JSONObject>();
    for( JSONObject o : objects ) objectList.add( o );
    parentObject.put( key, objectList );
}   

Implementation example:

JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
    buildObject( 
        new SimpleEntry( "child1Key1", "someValue" )
      , new SimpleEntry( "child1Key2", "someValue" ) 
    )
  , buildObject( 
        new SimpleEntry( "child2Key1", "someValue" )
      , new SimpleEntry( "child2Key2", "someValue" ) 
    )
);      

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS

We achieved in angular like below.

• 1. bind click event on input type file.
     2. Attach focus event with window and add condition if uploadPanel is true then show console.
     3. when click on input type file the boolean uploadPanel value is true. and dialogue box appear.
     4. when cancel OR Esc button click then dialogue box dispensary and console appear.

HTML

 <input type="file" formControlName="FileUpload" click)="handleFileInput($event.target.files)" />
          />

TS

this.uploadPanel = false;
handleFileInput(files: FileList) {
    this.fileToUpload = files.item(0);
    console.log("ggg" + files);
    this.uploadPanel = true;
  }



@HostListener("window:focus", ["$event"])
  onFocus(event: FocusEvent): void {
    if (this.uploadPanel == true) {
        console.log("cancel clicked")
        this.addSlot
        .get("FileUpload")
        .setValidators([
          Validators.required,
          FileValidator.validate,
          requiredFileType("png")
        ]);
      this.addSlot.get("FileUpload").updateValueAndValidity();
    }
  }

It's not good for several reasons:

• it mixes code and markup
• code written this way goes through eval
• and runs in the global scope

The simplest thing would be to add a name attribute to your <a> element, then you could do:

document.myelement.onclick = function() {
    window.popup('/map/', 300, 300, 'map');
    return false;
};

although modern best practise would be to use an id instead of a name, and use addEventListener() instead of using onclick since that allows you to bind multiple functions to a single event.

Select a cell in the cell range in which the data is imported, then Menu > Data > Properties > uncheck save query definition.

Properties will be greyed out unless a cell in the data import range is selected.

You can find out the range in which the data isimported by:

Menu > Data > Connections > (select connection) > Click here to see where the selected connections are used.

Using issubclass seemed like a clean way to write loglevels. It kinda feels odd using it... but it seems cleaner than other options.

class Error(object): pass
class Warn(Error): pass
class Info(Warn): pass
class Debug(Info): pass

class Logger():
    LEVEL = Info

    @staticmethod
    def log(text,level):
        if issubclass(Logger.LEVEL,level):
            print(text)
    @staticmethod
    def debug(text):
        Logger.log(text,Debug)   
    @staticmethod
    def info(text):
        Logger.log(text,Info)
    @staticmethod
    def warn(text):
        Logger.log(text,Warn)
    @staticmethod
    def error(text):
        Logger.log(text,Error)

You can use an empty <div> that is styled exactly like you want the line to appear:

HTML:

<div class="vertical-line"></div>

With exact height (overriding style in-line):

  div.vertical-line{_x000D_
      width: 1px; /* Line width */_x000D_
      background-color: black; /* Line color */_x000D_
      height: 100%; /* Override in-line if you want specific height. */_x000D_
      float: left; /* Causes the line to float to left of content. _x000D_
        You can instead use position:absolute or display:inline-block_x000D_
        if this fits better with your design */_x000D_
    }

<div class="vertical-line" style="height: 45px;"></div>

Style the border if you want 3D look:

    div.vertical-line{_x000D_
      width: 0px; /* Use only border style */_x000D_
      height: 100%;_x000D_
      float: left; _x000D_
      border: 1px inset; /* This is default border style for <hr> tag */_x000D_
    }

   <div class="vertical-line" style="height: 45px;"></div>

You can of course also experiment with advanced combinations:

  div.vertical-line{_x000D_
      width: 1px;_x000D_
      background-color: silver;_x000D_
      height: 100%;_x000D_
      float: left;_x000D_
      border: 2px ridge silver ;_x000D_
      border-radius: 2px;_x000D_
    }

 <div class="vertical-line" style="height: 45px;"></div>

You can use hasOwnProperty() as well as in operator.

I believe the example you've posted is using HTML5, which allows you to jump to any DOM element with the matching ID attribute. To support older browsers, you'll need to change:

<div id="timeline" name="timeline" ...>

To the old format:

<a name="timeline" />

You'll then be able to navigate to /academics/page.html#timeline and jump right to that section.

Also, check out this similar question.

Aside: Note that the standard LINQ operators (as per the earlier example) don't change the existing list - list.OrderBy(...).ToList() will create a new list based on the re-ordered sequence. It is pretty easy, however, to create an extension method that allows you to use lambdas with List<T>.Sort:

static void Sort<TSource, TValue>(this List<TSource> list,
    Func<TSource, TValue> selector)
{
    var comparer = Comparer<TValue>.Default;
    list.Sort((x,y) => comparer.Compare(selector(x), selector(y)));
}

static void SortDescending<TSource, TValue>(this List<TSource> list,
    Func<TSource, TValue> selector)
{
    var comparer = Comparer<TValue>.Default;
    list.Sort((x,y) => comparer.Compare(selector(y), selector(x)));
}

Then you can use:

list.Sort(x=>x.SomeProp); // etc

This updates the existing list in the same way that List<T>.Sort usually does.

More precisely, you have to force the addition of the tag, then push with option --tags and -f:

git tag -f -a <tagname>
git push -f --tags

beware when comparing numbers that are package versions, like checking if grep 2.20 is greater than version 2.6:

$ awk 'BEGIN { print (2.20 >= 2.6) ? "YES" : "NO" }'
NO

$ awk 'BEGIN { print (2.2 >= 2.6) ? "YES" : "NO" }'
NO

$ awk 'BEGIN { print (2.60 == 2.6) ? "YES" : "NO" }'
YES

I solved such problem with such shell/awk function:

# get version of GNU tool
toolversion() {
    local prog="$1" operator="$2" value="$3" version

    version=$($prog --version | awk '{print $NF; exit}')

    awk -vv1="$version" -vv2="$value" 'BEGIN {
        split(v1, a, /\./); split(v2, b, /\./);
        if (a[1] == b[1]) {
            exit (a[2] '$operator' b[2]) ? 0 : 1
        }
        else {
            exit (a[1] '$operator' b[1]) ? 0 : 1
        }
    }'
}

if toolversion grep '>=' 2.6; then
   # do something awesome
fi

m1 = (y2 - y1) / (x2 - x1)

if perpendicular two lines:

m1*m2 = -1

then

m2 = -1 / m1 //if (m1 == 0, then your line should have an equation like x = b)

y = m2*x + b //b is offset of new perpendicular line.. 

b is something if you want to pass it from a point you defined

Faced with same issue

ImportError: No module named numpy

So, in our case (we are use PIP and python 2.7) the solution was SPLIT pip install commands :

From

RUN pip install numpy scipy pandas sklearn

TO

RUN pip install numpy scipy
RUN pip install pandas sklearn

Solution found here : https://github.com/pandas-dev/pandas/issues/25193, it's related latest update of pandas to v0.24.0

I) if you need to calculate the elapsed time in seconds between two timestamp columns try this:

SELECT 
    extract ( day from (end_timestamp - start_timestamp) )*86400 
    + extract ( hour from (end_timestamp - start_timestamp) )*3600 
    + extract ( minute from (end_timestamp - start_timestamp) )*60 
    + extract ( second from (end_timestamp - start_timestamp) ) 
FROM table_name

II) if you want to just show the time difference in character format try this:

SELECT to_char (end_timestamp - start_timestamp) FROM table_name

This is all you need:

background-repeat: no-repeat;

The HAVING option can be used for this purpose and query should be

SELECT word, COUNT(*) FROM words 
GROUP BY word
HAVING COUNT(*) > 1;

you can use serialize method of jquery to get form values. Try like this

<form action="target.php" method="post" >
<input type="text" name="lname" />
<input type="text" name="fname" />
<input type="buttom" name ="send" onclick="return f(this.form) " >
</form>

function f( form ){
    var formData = $(form).serialize();
    att=form.attr("action") ;
    $.post(att, formData).done(function(data){
        alert(data);
    });
    return true;
}

NVL and COALESCE are used to achieve the same functionality of providing a default value in case the column returns a NULL.

The differences are:

1. NVL accepts only 2 arguments whereas COALESCE can take multiple arguments
2. NVL evaluates both the arguments and COALESCE stops at first occurrence of a non-Null value.
3. NVL does a implicit datatype conversion based on the first argument given to it. COALESCE expects all arguments to be of same datatype.
4. COALESCE gives issues in queries which use UNION clauses. Example below
5. COALESCE is ANSI standard where as NVL is Oracle specific.

Examples for the third case. Other cases are simple.

select nvl('abc',10) from dual; would work as NVL will do an implicit conversion of numeric 10 to string.

select coalesce('abc',10) from dual; will fail with Error - inconsistent datatypes: expected CHAR got NUMBER

Example for UNION use-case

SELECT COALESCE(a, sysdate) 
from (select null as a from dual 
      union 
      select null as a from dual
      );

fails with ORA-00932: inconsistent datatypes: expected CHAR got DATE

SELECT NVL(a, sysdate) 
from (select null as a from dual 
      union 
      select null as a from dual
      ) ;

succeeds.

You are passing the value of the memory location of the first member of the array.

Therefore when you start modifying the array inside the function, you are modifying the original array.

Remember that a[1] is *(a+1).

What you do is add a welcome file in your web.xml

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

And then add this to your servlet mappings so that when someone goes to the root of your application, they get sent to index.html internally and then the mapping will internally send them to the servlet you map it to

<servlet-mapping>
    <servlet-name>MainActions</servlet-name>
    <url-pattern>/main</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>MainActions</servlet-name>
    <url-pattern>/index.html</url-pattern>
</servlet-mapping>

End result: You visit /Application, but you are presented with /Application/MainActions servlet without disrupting any other root requests.

Get it? So your app still sits at a sub url, but automatically gets presented when the user goes to the root of your site. This allows you to have the /images/bob.img still go to the regular place, but '/' is your app.

I also had the same problem, I had assumed that Laravel is installed "out of the box" but it seems it isn't. I SSH'ed to the machine and ran these commands:

cd Code
sudo composer self-update #not necessary, but I did it anyways
composer create-project laravel/laravel Laravel --prefer-dist

And everything was running as usual.

In your stylesheet add:

@media print
{    
    .no-print, .no-print *
    {
        display: none !important;
    }
}

Then add class='no-print' (or add the no-print class to an existing class statement) in your HTML that you don't want to appear in the printed version, such as your button.

I just have this error. You can delete the files and run the compiling command again:

$ sudo rm /Users/Chaklader/.m2/repository/org/apache/poi/poi/3.17/poi-3.17.jar
$ sudo rm /Users/Chaklader/.m2/repository/com/fasterxml/jackson/core/jackson-databind/2.7.5/jackson-databind-2.7.5.jar
$ sudo rm /Users/Chaklader/.m2/repository/com/fasterxml/jackson/core/jackson-core/2.7.5/jackson-core-2.7.5.jar

Now, run the command for the clean compile:

$ mvn -U clean compile

I'm pretty sure it is technically impossible in SQL Server to have a True 1 to 1 relationship, as that would mean you would have to insert both records at the same time (otherwise you'd get a constraint error on insert), in both tables, with both tables having a foreign key relationship to each other.

That being said, your database design described with a foreign key is a 1 to 0..1 relationship. There is no constrain possible that would require a record in tableB. You can have a pseudo-relationship with a trigger that creates the record in tableB.

So there are a few pseudo-solutions

First, store all the data in a single table. Then you'll have no issues in EF.

Or Secondly, your entity must be smart enough to not allow an insert unless it has an associated record.

Or thirdly, and most likely, you have a problem you are trying to solve, and you are asking us why your solution doesn't work instead of the actual problem you are trying to solve (an XY Problem).

UPDATE

To explain in REALITY how 1 to 1 relationships don't work, I'll use the analogy of the Chicken or the egg dilemma. I don't intend to solve this dilemma, but if you were to have a constraint that says in order to add a an Egg to the Egg table, the relationship of the Chicken must exist, and the chicken must exist in the table, then you couldn't add an Egg to the Egg table. The opposite is also true. You cannot add a Chicken to the Chicken table without both the relationship to the Egg and the Egg existing in the Egg table. Thus no records can be every made, in a database without breaking one of the rules/constraints.

Database nomenclature of a one-to-one relationship is misleading. All relationships I've seen (there-fore my experience) would be more descriptive as one-to-(zero or one) relationships.

CodeIgniter has some error logging functions built in.

• Make your /application/logs folder writable
• In /application/config/config.php set
  $config['log_threshold'] = 1;
  or use a higher number, depending on how much detail you want in your logs
• Use log_message('error', 'Some variable did not contain a value.');
• To send an email you need to extend the core CI_Exceptions class method log_exceptions(). You can do this yourself or use this. More info on extending the core here

See http://www.codeigniter.com/user_guide/general/errors.html

As an alternative to using the import approach described in several answers, have a look a the configparser module.

The ConfigParser class implements a basic configuration file parser language which provides a structure similar to what you would find on Microsoft Windows INI files. You can use this to write Python programs which can be customized by end users easily.

The solution that worked for me. Delete this folder:

workspace/.metadata/.plugins/org.eclipse.e4.workbench

path = pd.read_csv(**'C:\Users\mravi\Desktop\filename'**)

The error is because of the path that is mentioned

Add 'r' before the path

path = pd.read_csv(**r'C:\Users\mravi\Desktop\filename'**)

This would work fine.

If you are using PHP you can use this, and I'm sure it's almost similar in other languages as well

$WebsiteURL = "https://api.telegram.org/bot".$BotToken;
$text = "<b>This</b> <i>is some Text</i>";
$Update = file_get_contents($WebsiteURL."/sendMessage?chat_id=$chat_id&text=$text&parse_mode=html);

echo $Update;

Here is the list of all tags that you can use

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<a href="http://www.example.com/">inline URL</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>

Here's the complete regexp to parse a URL.

WHERE condition_if_necessary

The problem with your conditional is in this part sshkey_result.rc == 1, because sshkey_result does not contain rc attribute and entire conditional fails.

If you want to check if file exists check exists attribute.

Here you can read more about stat module and how to use it.

Step 1 is always to first determine where the problem lies. Your title and most of your question seem to suggest that you're running into quite a low length limit on the length of a string in JavaScript / on browsers, an improbably low limit. You're not. Consider:

var str;

document.getElementById('theButton').onclick = function() {
  var build, counter;

  if (!str) {
    str = "0123456789";
    build = [];
    for (counter = 0; counter < 900; ++counter) {
      build.push(str);
    }
    str = build.join("");
  }
  else {
    str += str;
  }
  display("str.length = " + str.length);
};

Live copy

Repeatedly clicking the relevant button keeps making the string longer. With Chrome, Firefox, Opera, Safari, and IE, I've had no trouble with strings more than a million characters long:

str.length = 9000
str.length = 18000
str.length = 36000
str.length = 72000
str.length = 144000
str.length = 288000
str.length = 576000
str.length = 1152000
str.length = 2304000
str.length = 4608000
str.length = 9216000
str.length = 18432000

...and I'm quite sure I could got a lot higher than that.

So it's nothing to do with a length limit in JavaScript. You haven't show your code for sending the data to the server, but most likely you're using GET which means you're running into the length limit of a GET request, because GET parameters are put in the query string. Details here.

You need to switch to using POST instead. In a POST request, the data is in the body of the request rather than in the URL, and can be very, very large indeed.

To delete all DBs use:

for i in $(mongo --quiet --host $HOSTNAME --eval "db.getMongo().getDBNames()" | tr "," " ");

do mongo $i --host $HOSTNAME --eval "db.dropDatabase()";

As of 18/04/2017, no simple black or white list of characters and filenames is evident among the answers to this topic - and there are many replies.

The best suggestion I could come up with was to let the user name the file however he likes. Using an error handler when the application tries to save the file, catch any exceptions, assume the filename is to blame (obviously after making sure the save path was ok as well), and prompt the user for a new file name. For best results, place this checking procedure within a loop that continues until either the user gets it right or gives up. Worked best for me (at least in VBA).

finish your current_activity using method finish() onBack method of your current_activity

and then add below lines in onDestroy of the current_activity for Removing Force close

@Override
public void onDestroy()
{
    android.os.Process.killProcess(android.os.Process.myPid());
    super.onDestroy();
}

I was facing problem with Ngx line chart xAxisTickFormatting function which was called from HTML like this: [xAxisTickFormatting]="xFormat". I was unable to access my component's variable from the function declared. This solution helped me to resolve the issue to find the correct this. Hope this helps the Ngx line chart, users.

instead of using the function like this:

xFormat (value): string {
  return value.toString() + this.oneComponentVariable; //gives wrong result 
}

Use this:

 xFormat = (value) => {
   // console.log(this);
   // now you have access to your component variables
   return value + this.oneComponentVariable
 }

While former answer is absolutely correct, I prefer using the JOIN ON syntax to be sure that I know how do I join and on what fields. It would look something like this:

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

This syntax seperates completely the WHERE clause from the JOIN clause, making the statement more readable and easier for you to debug.

java.exe is associated with the console, whereas javaw.exe doesn't have any such association. So, when java.exe is run, it automatically opens a command prompt window where output and error streams are shown.

1st option -

You can nest REPLACE() functions up to 32 levels deep. It runs fast.

REPLACE
(REPLACE

(REPLACE (@str, '0', ''),
'1', ''),
'2', ''),
'3', ''),
'4', ''),

'8', ''),
'9', '')

2nd option -- do the reverse of -

Removing nonnumerical data out of a number + SQL

3rd option - if you want to use regex

then http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=27205

As mentioned you need to use obj.getTile()

But, in this case I think you are looking to use a Property.

public class Pin
{
    private string title;

    public Pin() { }

    public setTitle(string title) {
        this.title = title;
    }

    public String Title
    {
        get { return title; }
    }
}

This will allow you to use

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

@Giuseppe, you may want to consider this for a flexible specification of the plots arrangement (modified from here):

library(ggplot2)
library(gridExtra)
library(grid)

grid_arrange_shared_legend <- function(..., nrow = 1, ncol = length(list(...)), position = c("bottom", "right")) {

  plots <- list(...)
  position <- match.arg(position)
  g <- ggplotGrob(plots[[1]] + theme(legend.position = position))$grobs
  legend <- g[[which(sapply(g, function(x) x$name) == "guide-box")]]
  lheight <- sum(legend$height)
  lwidth <- sum(legend$width)
  gl <- lapply(plots, function(x) x + theme(legend.position = "none"))
  gl <- c(gl, nrow = nrow, ncol = ncol)

  combined <- switch(position,
                     "bottom" = arrangeGrob(do.call(arrangeGrob, gl),
                                            legend,
                                            ncol = 1,
                                            heights = unit.c(unit(1, "npc") - lheight, lheight)),
                     "right" = arrangeGrob(do.call(arrangeGrob, gl),
                                           legend,
                                           ncol = 2,
                                           widths = unit.c(unit(1, "npc") - lwidth, lwidth)))
  grid.newpage()
  grid.draw(combined)

}

Extra arguments nrow and ncol control the layout of the arranged plots:

dsamp <- diamonds[sample(nrow(diamonds), 1000), ]
p1 <- qplot(carat, price, data = dsamp, colour = clarity)
p2 <- qplot(cut, price, data = dsamp, colour = clarity)
p3 <- qplot(color, price, data = dsamp, colour = clarity)
p4 <- qplot(depth, price, data = dsamp, colour = clarity)
grid_arrange_shared_legend(p1, p2, p3, p4, nrow = 1, ncol = 4)
grid_arrange_shared_legend(p1, p2, p3, p4, nrow = 2, ncol = 2)

Well, in my case I had to test a Phone Number with the help of regex, and I was getting the same error,

Invalid regular expression: /+923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/: Nothing to repeat'

So, what was the error in my case was that + operator after the / in the start of the regex. So enclosing the + operator with square brackets [+], and again sending the request, worked like a charm.

Following will work:

/[+]923[0-9]{2}-(?!1234567)(?!1111111)(?!7654321)[0-9]{7}/

This answer may be helpful for those, who got the same type of error, but their chances of getting the error from this point of view, as mine! Cheers :)

There is no need to learn C before learning C++.

They are different languages. It is a common misconception that C++ is in some way dependent on C and not a fully specified language on its own.

Just because C++ shares a lot of the same syntax and a lot of the same semantics, does not mean you need to learn C first.

If you learn C++ you will eventually learn most of C with some differences between the languages that you will learn over time. In fact its a very hard thing to write proper C++ because intermediate C++ programmers tend to write C/C++.That is true whether or not you started with C or started with C++.

If you know C first, then that is good plus to learning C++. You will start with knowing a chunk of the language. If you do not know C first then there is no point focusing on a different language. There are plenty of good books and tutorials available that start you from knowing nothing and will cover anything you would learn from C which applies to C++ as well.

Please see further reasoning in this answer.

You have to use code similar to this:

echo "<div id='divwithform'>";

if(isset($_POST['submit']))  // if form was submitted (if you came here with form data)
{
    echo "Success";
}
else                // if form was not submitted (if you came here without form data)
{
    echo "<form> ... </form>";
} 

echo "</div>";

Code with if like this is typical for many pages, however this is very simplified.

Normally, you have to validate some data in first "if" (check if form fields were not empty etc).

Please visit www.thenewboston.org or phpacademy.org. There are very good PHP video tutorials, including forms.

Absolute positioning is based on co-ordiantes of the display:

position:absolute;
top:0px;
left:0px;

^ places the element top left of the window.

Relative position is relative to where the element is placed:

position:relative;
top:1px;
left:1px;

^ places the element 1px down and 1px from the left of where it originally sat :)

Try this:

import math
print [value for value in x if not math.isnan(value)]

For more, read on List Comprehensions.

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

The sizzle selector engine (what powers JQuery) is perfectly geared up for this:

var elements = $('input[type=text]');

Or

var elements = $('input:text');

I manually started mysql in the system preferences pane by initialising the database and then starting it. This solved my problem.

From all of the above, I came up with this version. This version also works for me in the mac recovery terminal.

find ./ -name '*.xsl' -exec cp -prv '{}' '/path/to/targetDir/' ';'

It will look in the current directory and recursively in all of the sub directories for files with the xsl extension. It will copy them all to the target directory.

cp flags are:

• p - preserve attributes of the file
• r - recursive
• v - verbose (shows you whats being copied)

Well, simple options are:

• string.Format:

  string x = string.Format("first line{0}second line", Environment.NewLine);
  

• String concatenation:

  string x = "first line" + Environment.NewLine + "second line";
  

• String interpolation (in C#6 and above):

  string x = $"first line{Environment.NewLine}second line";
  

You could also use \n everywhere, and replace:

string x = "first line\nsecond line\nthird line".Replace("\n",
                                                         Environment.NewLine);

Note that you can't make this a string constant, because the value of Environment.NewLine will only be available at execution time.

The following works in Firefox and Opera (sorry, I do not have access to other browsers at the moment):

<div class="form-field">
    <input id="option1" type="radio" name="opt"/>
    <label for="option1">Option 1</label>
</div>

The CSS:

.form-field * {
    vertical-align: middle;
}

My gut told me the same thing when I came across this design.

I am working on a code base where there are three dbContexts to one database. 2 out of the 3 dbcontexts are dependent on information from 1 dbcontext because it serves up the administrative data. This design has placed constraints on how you can query your data. I ran into this problem where you cannot join across dbcontexts. Instead what you are required to do is query the two separate dbcontexts then do a join in memory or iterate through both to get the combination of the two as a result set. The problem with that is instead of querying for a specific result set you are now loading all your records into memory and then doing a join against the two result sets in memory. It can really slow things down.

I would ask the question "just because you can, should you?"

See this article for the problem I came across related to this design. The specified LINQ expression contains references to queries that are associated with different contexts

Lots of answers already, here's mine.

I extend AppCompatSpinner and add a method pgmSetSelection(int pos) that allows programmatic selection setting without triggering a selection callback. I've coded this with RxJava so that the selection events are delivered via an Observable.

package com.controlj.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.AdapterView;

import io.reactivex.Observable;

/**
 * Created by clyde on 22/11/17.
 */

public class FilteredSpinner extends android.support.v7.widget.AppCompatSpinner {
    private int lastSelection = INVALID_POSITION;


    public void pgmSetSelection(int i) {
        lastSelection = i;
        setSelection(i);
    }

    /**
     * Observe item selections within this spinner. Events will not be delivered if they were triggered
     * by a call to setSelection(). Selection of nothing will return an event equal to INVALID_POSITION
     *
     * @return an Observable delivering selection events
     */
    public Observable<Integer> observeSelections() {
        return Observable.create(emitter -> {
            setOnItemSelectedListener(new OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                    if(i != lastSelection) {
                        lastSelection = i;
                        emitter.onNext(i);
                    }
                }

                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {
                    onItemSelected(adapterView, null, INVALID_POSITION, 0);
                }
            });
        });
    }

    public FilteredSpinner(Context context) {
        super(context);
    }

    public FilteredSpinner(Context context, int mode) {
        super(context, mode);
    }

    public FilteredSpinner(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FilteredSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public FilteredSpinner(Context context, AttributeSet attrs, int defStyleAttr, int mode) {
        super(context, attrs, defStyleAttr, mode);
    }
}

An example of its usage, called in onCreateView() in a Fragment for example:

    mySpinner = view.findViewById(R.id.history);
    mySpinner.observeSelections()
        .subscribe(this::setSelection);

where setSelection() is a method in the enclosing view that looks like this, and which is called both from user selection events via the Observable and also elsewhere programmatically, so the logic for handling selections is common to both selection methods.

private void setSelection(int position) {
    if(adapter.isEmpty())
        position = INVALID_POSITION;
    else if(position >= adapter.getCount())
        position = adapter.getCount() - 1;
    MyData result = null;
    mySpinner.pgmSetSelection(position);
    if(position != INVALID_POSITION) {
        result = adapter.getItem(position);
    }
    display(result);  // show the selected item somewhere
}

Based on the official documentation:

dummies = pd.get_dummies(df['Category']).rename(columns=lambda x: 'Category_' + str(x))
df = pd.concat([df, dummies], axis=1)
df = df.drop(['Category'], inplace=True, axis=1)

There is also a nice post in the FastML blog.

Removing any and all whitespace:

foo = ''.join(foo.split())

Removing last three characters:

foo = foo[:-3]

Converting to capital letters:

foo = foo.upper()

All of that code in one line:

foo = ''.join(foo.split())[:-3].upper()

Header files, you'll be the death of me...

Finally got it to work by adding (including quotes)

"${PODS_ROOT}/BuildHeaders"

to the User Header Search Paths entry, and checking 'recursive'.

There are 2 solutions for your problem:

1. Either you set a fixed size of the Tkinter window; mw.geometry('500x500')

OR

2. Make the Frame adjust to the size of the window automatically;back.place(x = 0, y = 0, relwidth = 1, relheight = 1)

*The second option should be used in place of back.pack()

If you have to use the same page as the action, you cannot use onSubmit="window.close();" as it will close the window before the response is received. You have to dinamycally output a JS snippet that closes the window after the SQL data is processed. It would however be far more elegant to use another page as the form action.

Simply push this branch to a different branch name

 git push -u origin localBranch:remoteBranch

Depending on the situation, it is often helpful to make the image a background image of a div with CSS.

<div id='my-image'></div>

Then in CSS:

#my-image {
    background-image: url('/img/foo.png');
    width: ???px;
    height: ???px;
}

See this JSFiddle for a live example with a button and a different sizing option.

For those who do not have 4.5, Here is my library function that reads json. It requires a project reference to System.Web.Extensions.

using System.Web.Script.Serialization;

public object DeserializeJson<T>(string Json)
{
    JavaScriptSerializer JavaScriptSerializer = new JavaScriptSerializer();
    return JavaScriptSerializer.Deserialize<T>(Json);
}

Usually, json is written out based on a contract. That contract can and usually will be codified in a class (T). Sometimes you can take a word from the json and search the object browser to find that type.

Example usage:

Given the json

{"logEntries":[],"value":"My Code","text":"My Text","enabled":true,"checkedIndices":[],"checkedItemsTextOverflows":false}

You could parse it into a RadComboBoxClientState object like this:

string ClientStateJson = Page.Request.Form("ReportGrid1_cboReportType_ClientState");
RadComboBoxClientState RadComboBoxClientState = DeserializeJson<RadComboBoxClientState>(ClientStateJson);
return RadComboBoxClientState.Value;

I my case I'd manually moved a .war file to /var/lib/tomcat9/webapps and unzipped it, then did "chown -R tomcat:tomcat *" in that directory and it resolved it.

Errr? Just use regular expressions! :)

function isInteger(val) {
  return val.match(/^[0-9]$/)
}

function isFloat(val) {
  return val.match(/^[0-9]*/\.[0-9]+$/)
}

Given your representation, your function is as efficient as can be done. Of course, as noted by others (and as practiced in languages older than Lua), the solution to your real problem is to change representation. When you have tables and you want sets, you turn tables into sets by using the set element as the key and true as the value. +1 to interjay.

Maybe you're trying to uninstall an app that is a phone administrator.

To be able to uninstall it, go to Seetings > Security > Phone Administrators. If the app is listed, uncheck it and confirm the operation.

After that, you should be able to uninstall it using the App settings area or adb.

If you use AngularJs ngModel directive, remember that the value of value attribute does not bind on ngModel field.You have to init it by yourself and the best way to do it,is

<input type="text"
       id="rootFolder"
       ng-init="rootFolders = 'Bob'"
       ng-model="rootFolders"
       disabled="disabled"
       value="Bob"
       size="40"/>

Usually, deleting the current emulator that doesn't work anymore and creating it again will solve the issue. I've had it 5 minutes ago and that's how I solved it.

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

You most likely mean "yyyy-MM-dd" small latter 'm' would imply minutes section.

You should do two things

• add spring.jackson.serialization.write-dates-as-timestamps:false in your application.properties this will disable converting dates to timestamps and instead use a ISO-8601 compliant format

• You can than customize the format by annotating the getter method of you dateOfBirth property with @JsonFormat(pattern="yyyy-MM-dd")

• demo: http://so.lucafilosofi.com/how-do-you-create-a-marker-with-a-custom-icon-for-google-maps-api-v3

marker = new google.maps.Marker({
    map:map,
    // draggable:true,
    // animation: google.maps.Animation.DROP,
    position: new google.maps.LatLng(59.32522, 18.07002),
    icon: 'http://cdn.com/my-custom-icon.png' // null = default icon
  });

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *
FROM    one
JOIN    two
ON      one.one_name = two.one_name
ORDER BY
        one.id

I had a very simple solution for this, after struggling with all the methods of fixing this.

i had the problem on my mobile IOS devices.

css (desktop)

#ci-hero-11 .widget-wrap , #ci-hero-12 .widget-wrap {
background-size: auto;
background-attachment: fixed;
}

.widget-wrap {
background-attachment: scroll;
}

Then i overwrite it with media query removing "fixed" as background attachment.

css (mobile)

@media (max-width: 767px) {
#ci-hero-11 .widget-wrap , #ci-hero-12 .widget-wrap {

    background-attachment: initial;

}
}

initial - Sets this property to its default value. I think because IOS doesn't accept 'fixed' it falls back to a default value it accepts, scroll.

This worked for me on every device. Hope it helps someone else as well.

Building on @Tim's example to make a self-contained method:

import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.util.ArrayList;

public class Shell {

    /** Returns null if it failed for some reason.

            Process process = 
                new ProcessBuilder(new String[] {"bash", "-c", cmdline})
                    .redirectErrorStream(true)
                    .directory(new File(directory))
                    .start();

            ArrayList<String> output = new ArrayList<String>();
            BufferedReader br = new BufferedReader(
                new InputStreamReader(process.getInputStream()));
            String line = null;
            while ( (line = br.readLine()) != null )
                output.add(line);

            //There should really be a timeout here.
            if (0 != process.waitFor())
                return null;

            return output;

        } catch (Exception e) {

(The test example is a command that lists all files in a directory and its subdirectories, recursively, in chronological order.)

By the way, if somebody can tell me why I need four and eight backslashes there, instead of two and four, I can learn something. There is one more level of unescaping happening than what I am counting.

Edit: Just tried this same code on Linux, and there it turns out that I need half as many backslashes in the test command! (That is: the expected number of two and four.) Now it's no longer just weird, it's a portability problem.

To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php

<?php
$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$image->setImageFormat('png');
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
echo "\n";

The R packages geosphere will calculate bearingRhumb, which is a constant bearing line given an origin point and easting/northing. The easting and northing must be in a matrix or vector. The origin point for a wind rose is 0,0. The following code seems to readily resolve the issue:

windE<-wind$uasE
windN<-wind$vasN
wind_matrix<-cbind(windE, windN)
wind$wind_dir<-bearingRhumb(c(0,0), wind_matrix)
wind$wind_dir<-round(wind$wind_dir, 0)

I'm a fan of gitk's graphical UI to visualize git repos. You can view the last item stashed with:

gitk stash

You can also use view any of your stashed changes (as listed by git stash list). For example:

gitk stash@{2}

In the below screenshot, you can see the stash as a commit in the upper-left, when and where it came from in commit history, the list of files modified on the bottom right, and the line-by-line diff in the lower-left. All while the stash is still tucked away.

Assuming the items override ToString appropriately:

public void WriteToConsole(IEnumerable items)
{
    foreach (object o in items)
    {
        Console.WriteLine(o);
    }
}

(There'd be no advantage in using generics in this loop - we'd end up calling Console.WriteLine(object) anyway, so it would still box just as it does in the foreach part in this case.)

EDIT: The answers using List<T>.ForEach are very good.

My loop above is more flexible in the case where you have an arbitrary sequence (e.g. as the result of a LINQ expression), but if you definitely have a List<T> I'd say that List<T>.ForEach is a better option.

One advantage of List<T>.ForEach is that if you have a concrete list type, it will use the most appropriate overload. For example:

List<int> integers = new List<int> { 1, 2, 3 };
List<string> strings = new List<string> { "a", "b", "c" };

integers.ForEach(Console.WriteLine);
strings.ForEach(Console.WriteLine);

When writing out the integers, this will use Console.WriteLine(int), whereas when writing out the strings it will use Console.WriteLine(string). If no specific overload is available (or if you're just using a generic List<T> and the compiler doesn't know what T is) it will use Console.WriteLine(object).

Note the use of Console.WriteLine as a method group, by the way. This is more concise than using a lambda expression, and actually slightly more efficient (as the delegate will just be a call to Console.WriteLine, rather than a call to a method which in turn just calls Console.WriteLine).

Here is a situation where there is definitely a need for inheritance for static fields and methods:

abstract class Animal
{
  protected static string[] legs;

  static Animal() {
    legs=new string[0];
  }

  public static void printLegs()
  {
    foreach (string leg in legs) {
      print(leg);
    }
  }
}


class Human: Animal
{
  static Human() {
    legs=new string[] {"left leg", "right leg"};
  }
}


class Dog: Animal
{
  static Dog() {
    legs=new string[] {"left foreleg", "right foreleg", "left hindleg", "right hindleg"};
  }
}


public static void main() {
  Dog.printLegs();
  Human.printLegs();
}


//what is the output?
//does each subclass get its own copy of the array "legs"?

A connect failed: ECONNREFUSED (Connection refused) most likely means that there is nothing listening on that port AND that IP address. Possible explanations include:

• the service has crashed or hasn't been (successfully!) started,
• your client is trying to connect using the wrong IP address or port,
• your client is trying to connect using a DNS name that resolves to the wrong IP, or
• server access is being blocked by a firewall that is "refusing" on the server/service's behalf. This is pretty unlikely given that normal practice (these days) is for firewalls to "blackhole" all unwanted connection attempts.

Note that while you have an array variable called urls, it cannot contain real URLs. There is no overload of the Socket constructor that takes a real URL in any form. Indeed, if you supplied a URL in string form like this:

 new Socket("http://example.com", 42)

the result would be a different exception. Likewise, if you attempt to connect to an IP address on a network that you can't route to (e.g. "a different WiFi network"), then you will get a different exception; e.g. "host not found", "no route to host" or "no route to network".
