Hmm... well, the simple way that comes to mind is to convert it to a dict

d = dict(thelist)

and access d[53].

EDIT: Oops, misread your question the first time. It sounds like you actually want to get the index where a given number is stored. In that case, try

dict((t[0], i) for i, t in enumerate(thelist))

instead of a plain old dict conversion. Then d[53] would be 2.

Here's other way of getting Zscore using custom function:

In [6]: import pandas as pd; import numpy as np

In [7]: np.random.seed(0) # Fixes the random seed

In [8]: df = pd.DataFrame(np.random.randn(5,3), columns=["randomA", "randomB","randomC"])

In [9]: df # watch output of dataframe
Out[9]:
    randomA   randomB   randomC
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
2  0.950088 -0.151357 -0.103219

4  0.761038  0.121675  0.443863

## Create custom function to compute Zscore 
In [10]: def z_score(df):
   ....:         df.columns = [x + "_zscore" for x in df.columns.tolist()]
   ....:         return ((df - df.mean())/df.std(ddof=0))
   ....:

## make sure you filter or select columns of interest before passing dataframe to function

I prefer to upgrade all homebrew formulae and homebrew cask formulae.

I added a Bourne shell function to my environment for this one (I load a .bashrc)

function updatebrew() {
set -x;
brew update;
brew cleanup;
brew cask upgrade --greedy
)
}

• set -x for transparency: So that the terminal outputs whatever Homebrew is doing in the background.
• brew update to update homebrew formulas
• brew cleanup to remove any change left over after installations
• brew cask upgrade --greedy will install all casks; both those with versioning information and those without

If you're running into javascript namespace collisions, you can use Bootstrap's noConflict() function make it cede functionality to jQuery UI.

With a signal handler.

Here is a simple example flipping a bool used in main():

#include <signal.h>

static volatile int keepRunning = 1;

void intHandler(int dummy) {
    keepRunning = 0;
}

// ...

int main(void) {

   signal(SIGINT, intHandler);

   while (keepRunning) { 
      // ...

Edit in June 2017: To whom it may concern, particularly those with an insatiable urge to edit this answer. Look, I wrote this answer seven years ago. Yes, language standards change. If you really must better the world, please add your new answer but leave mine as is. As the answer has my name on it, I'd prefer it to contain my words too. Thank you.

When I open a "DOS" command prompt, I use a batch file which sets all of the options I need and adds my old-time dos utilities to the path too.

@set path=%path%;c:\utils
@doskey cd=cd/d $*
@cd \wip
@cmd.exe

The doskey line sets the CD command so that it will do both drive and folder simultaneously. If this doesn't work, it is possibly because of the version of windows that you're running.

Get the time in milliseconds, minus your minutes in milliseconds and convert it to Date. Here you need to objectify one!!!

    int minutes = 60;
    long currentDateTime = System.currentTimeMillis();
    Date currentDate = new Date(currentDateTime - minutes*60*1000);
    System.out.println(currentDate);

Try

.abutton { 
  background: #bada55; padding: 5px; border-radius: 5px; 
  transition: 1s; text-decoration: none; color: black;
}
.abutton:hover { background: #2a2;  }

<a href="https://example.com" class="abutton">Continue</a>

Unformatted and formatted:

$price = $product->getPrice();
$formatted = Mage::helper('core')->currency($price, true, false);

Or use:

Mage::helper('core')->formatPrice($price, true);

Using dlpyr::mutate and forcats::fct_recode:

library(dplyr)
library(forcats)

iris <- iris %>%  
  mutate(Species = fct_recode(Species,
    "Virginica" = "virginica",
    "Versicolor" = "versicolor"
  )) 

iris %>% 
  count(Species)

# A tibble: 3 x 2
     Species     n
      <fctr> <int>
1     setosa    50
2 Versicolor    50
3  Virginica    50   

Just in case someone makes the same error I did before stumbling on this page, that is, adding CSS reset rules (like the very popular reset by Eric Meyer used on millions of websites) after including bootstrap.

Also, perhaps I should point out that such reset won't be necessary with bootstrap given bootsrap actually implements the normalize.css v3.0.2 reset.

You could use an image submit button:

<input type="image"  id="saveform" src="logg.png " alt="Submit Form" />

Guys, I found that JQuery has only one effect: the page is reloaded when the back button is pressed. This has nothing to do with "ready".

How does this work? Well, JQuery adds an onunload event listener.

// http://code.jquery.com/jquery-latest.js
jQuery(window).bind("unload", function() { // ...

By default, it does nothing. But somehow this seems to trigger a reload in Safari, Opera and Mozilla -- no matter what the event handler contains.

[edit(Nickolay): here's why it works that way: webkit.org, developer.mozilla.org. Please read those articles (or my summary in a separate answer below) and consider whether you really need to do this and make your page load slower for your users.]

Can't believe it? Try this:

<body onunload=""><!-- This does the trick -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

You will see similar results when using JQuery.

You may want to compare to this one without onunload

<body><!-- Will not reload on back button -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

As stated, all objects in sharepoint contain some sort of unique identifier (often an integer based counter for list items, and GUIDs for lists).

That said, there is also a feature available at http://www.codeplex.com/features called "Unique Column Policy", designed to add an other column with a unique value. A complete writeup is available at http://scothillier.spaces.live.com/blog/cns!8F5DEA8AEA9E6FBB!293.entry

The mistake I made that coerced this error was attempting to rename a column in a loop that I was no longer selecting in my SQL. This could also be caused by trying to do the same thing in a column that you were planning to select. Make sure the column that you are trying to change actually exists.

There are built-in functions in Python for "right" and "left", if you are looking for a boolean result.

str = "this_is_a_test"
left = str.startswith("this")
print(left)
> True

right = str.endswith("test")
print(right)
> True

Another option is to convert the YAML to JSON, then use jq to interact with the JSON representation either to extract information from it or edit it.

I wrote a simple bash script that contains this glue - see Y2J project on GitHub

Here is my solution:

public static String encode(String key, String data) throws Exception {
  Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
  SecretKeySpec secret_key = new SecretKeySpec(key.getBytes("UTF-8"), "HmacSHA256");
  sha256_HMAC.init(secret_key);

  return Hex.encodeHexString(sha256_HMAC.doFinal(data.getBytes("UTF-8")));
}

public static void main(String [] args) throws Exception {
  System.out.println(encode("key", "The quick brown fox jumps over the lazy dog"));
}

Or you can return the hash encoded in Base64:

Base64.encodeBase64String(sha256_HMAC.doFinal(data.getBytes("UTF-8")));

The output in hex is as expected:

f7bc83f430538424b13298e6aa6fb143ef4d59a14946175997479dbc2d1a3cd8

Without content, the height has no value to calculate the percentage of. The width, however, will take the percentage from the DOM, if no parent is specified. (Using your example) Placing the second div inside the first div, would have rendered a result...example below...

<div id="working">
  <div id="not-working"></div>
</div>

The second div would be 30% of the first div's height.

Edit: This answer is wrong, even though, strictly speaking, the code works. I'm only leaving it here because the discussion under it is too useful. This other answer is the best answer given at the time I last edited this: How do I pass a unique_ptr argument to a constructor or a function?

The basic idea of ::std::move is that people who are passing you the unique_ptr should be using it to express the knowledge that they know the unique_ptr they're passing in will lose ownership.

This means you should be using an rvalue reference to a unique_ptr in your methods, not a unique_ptr itself. This won't work anyway because passing in a plain old unique_ptr would require making a copy, and that's explicitly forbidden in the interface for unique_ptr. Interestingly enough, using a named rvalue reference turns it back into an lvalue again, so you need to use ::std::move inside your methods as well.

This means your two methods should look like this:

Base(Base::UPtr &&n) : next(::std::move(n)) {} // Spaces for readability

void setNext(Base::UPtr &&n) { next = ::std::move(n); }

Then people using the methods would do this:

Base::UPtr objptr{ new Base; }
Base::UPtr objptr2{ new Base; }
Base fred(::std::move(objptr)); // objptr now loses ownership
fred.setNext(::std::move(objptr2)); // objptr2 now loses ownership

As you see, the ::std::move expresses that the pointer is going to lose ownership at the point where it's most relevant and helpful to know. If this happened invisibly, it would be very confusing for people using your class to have objptr suddenly lose ownership for no readily apparent reason.

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

function deltree_cat($folder)
{
    if (is_dir($folder))
    {
             $handle = opendir($folder);
             while ($subfile = readdir($handle))
             {
                     if ($subfile == '.' or $subfile == '..') continue;
                     if (is_file($subfile)) unlink("{$folder}/{$subfile}");
                     else deltree_cat("{$folder}/{$subfile}");
             }
             closedir($handle);
             rmdir ($folder);
     }
     else
     {
        unlink($folder);
     }
}

With an OR (||) operation, if any one of the conditions are true, the result is true.

I think you want an AND (&&) operation here.

I learned this from http://www.pcsalt.com/android/edittext-with-single-line-line-wrapping-and-done-action-in-android/, though I don't like the website myself. If you want multiline BUT want to retain the enter button as a post button, set the listview's "horizontally scrolling" to false.

android:scrollHorizontally="false"

If it doesn't work in xml, doing it programmatically weirdly works.

listView.setHorizontallyScrolling(false);

If you want to show error messages on form submission, you can use condition form.$submitted to check if an attempt was made to submit the form. Check following example.

<form name="myForm" novalidate ng-submit="myForm.$valid && createUser()">
  <input type="text" name="name" ng-model="user.name" placeholder="Enter name of user" required>
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user name.</div>
  </div>

  <input type="text" name="address" ng-model="user.address" placeholder="Enter Address" required ng-maxlength="30">
  <div ng-messages="myForm.name.$error" ng-if="myForm.$submitted">
    <div ng-message="required">Please enter user address.</div>
    <div ng-message="maxlength">Should be less than 30 chars</div>
  </div>

  <button type="submit">
    Create user
  </button>
</form>

By default, the runserver command starts the development server on the internal IP at port 8000.

If you want to change the server’s port, pass it as a command-line argument. For instance, this command starts the server on port 8080:

python manage.py runserver 8080

Looks like you have a bad practice here but not where you think.

Catching an IllegalArgumentException to rethrow another RuntimeException with a clearer message might look like a good idea but it is not. Because it means you care about messages in your exceptions.

If you care about messages in your exceptions, then it means that your user is somehow seeing your exceptions. This is bad.

If you want to provide an explicit error message to your user, you should check the validity of the enum value when parsing user input and send the appropriate error message in the response if user input is incorrect.

Something like:

// This code uses pure fantasy, you are warned!
class MyApi
{
    // Return the 24-hour from a 12-hour and AM/PM

    void getHour24(Request request, Response response)
    {
        // validate user input
        int nTime12 = 1;
        try
        {
            nTime12 = Integer.parseInt(request.getParam("hour12"));
            if( nTime12 <= 0 || nTime12 > 12 )
            {
                throw new NumberFormatException();
            }
        }
        catch( NumberFormatException e )
        {
            response.setCode(400); // Bad request
            response.setContent("time12 must be an integer between 1 and 12");
            return;
        }

        AMPM pm = null;
        try
        {
            pm = AMPM.lookup(request.getParam("pm"));
        }
        catch( IllegalArgumentException e )
        {
            response.setCode(400); // Bad request
            response.setContent("pm must be one of " + AMPM.values());
            return;
        }

        response.setCode(200);
        switch( pm )
        {
            case AM:
                response.setContent(nTime12);
                break;
            case PM:
                response.setContent(nTime12 + 12);
                break;
        }
        return;
    }
}

This should work:

function Klass() {
   var instance = this;
   Klass = function () { return instance; }
}

Here is another method to add days on date using dateutil's relativedelta.

from datetime import datetime
from dateutil.relativedelta import relativedelta

print 'Today: ',datetime.now().strftime('%d/%m/%Y %H:%M:%S') 
date_after_month = datetime.now()+ relativedelta(day=1)
print 'After a Days:', date_after_month.strftime('%d/%m/%Y %H:%M:%S')

Output:

Today: 25/06/2015 20:41:44

After a Days: 01/06/2015 20:41:44

An important part of using a key down on tab is knowing that tab will always try to do something already, don't forget to "return false" at the end.

Here is what I did. I have a function that runs on .blur and a function that swaps where my form focus is. Basically it adds an input to the end of the form and goes there while running calculations on blur.

$(this).children('input[type=text]').blur(timeEntered).keydown(function (e) {
        var code = e.keyCode || e.which;
        if (code == "9") {
            window.tabPressed = true;
            // Here is the external function you want to call, let your external
            // function handle all your custom code, then return false to
            // prevent the tab button from doing whatever it would naturally do.
            focusShift($(this));
            return false;
        } else {
            window.tabPressed = false;
        }
        // This is the code i want to execute, it might be different than yours
        function focusShift(trigger) {
            var focalPoint = false;
            if (tabPressed == true) {
                console.log($(trigger).parents("td").next("td"));
                focalPoint = $(trigger).parents("td").next("td");

            }
            if (focalPoint) {
                $(focalPoint).trigger("click");
            }
        }
    });

SELECT x.name, x.summary, (x.summary / COUNT(*)) as percents_of_total
FROM tbl t
INNER JOIN

It depends on how you define better. If you want the code to look cleaner, you can use .Sum() as mentioned in other answers. If you want the operation to run quickly and you have a large array, you can make it parallel by breaking it into sub sums and then sum the results.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

I found this problem in the book "Illustrated Guide to Python 3". It was in a very early chapter that only discussed the math operations, no loops, no comparisons, no conditionals. How can you tell if a given year is a leap year?

Below is what I came up with:

y = y % 400
a = y % 4
b = y % 100
c = y // 100
ly = (0**a) * ((1-(0**b)) + 0**c)   # ly is not zero for leap years, else 0

I wanted something that would take two lists and could do what diff in bash does. Since this question pops up first when you search for "python diff two lists" and is not very specific, I will post what I came up with.

Using SequenceMather from difflib you can compare two lists like diff does. None of the other answers will tell you the position where the difference occurs, but this one does. Some answers give the difference in only one direction. Some reorder the elements. Some don't handle duplicates. But this solution gives you a true difference between two lists:

a = 'A quick fox jumps the lazy dog'.split()
b = 'A quick brown mouse jumps over the dog'.split()

from difflib import SequenceMatcher

for tag, i, j, k, l in SequenceMatcher(None, a, b).get_opcodes():
  if tag == 'equal': print('both have', a[i:j])
  if tag in ('delete', 'replace'): print('  1st has', a[i:j])
  if tag in ('insert', 'replace'): print('  2nd has', b[k:l])

This outputs:

both have ['A', 'quick']
  1st has ['fox']
  2nd has ['brown', 'mouse']
both have ['jumps']
  2nd has ['over']
both have ['the']
  1st has ['lazy']
both have ['dog']

Of course, if your application makes the same assumptions the other answers make, you will benefit from them the most. But if you are looking for a true diff functionality, then this is the only way to go.

For example, none of the other answers could handle:

a = [1,2,3,4,5]
b = [5,4,3,2,1]

But this one does:

  2nd has [5, 4, 3, 2]
both have [1]
  1st has [2, 3, 4, 5]

This code worked for me:

var updatedText = text.Normalize(NormalizationForm.FormD)
     .Where(c => CharUnicodeInfo.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)
     .ToArray();

However, please don't do this with names. It's not only an insult to people with umlauts/accents in their name, it can also be dangerously wrong in certain situations (see below). There are alternative writings instead of just removing the accent.

Furthermore, it's simply wrong and dangerous, e.g. if the user has to provide his name exactly how it occurs on the passport.

For example my name is written Zuberbühler and in the machine readable part of my passport you will find Zuberbuehler. By removing the umlaut, the name will not match with either part. This can lead to issues for the users.

You should rather disallow umlauts/accent in an input form for names so the user can write his name correctly without its umlaut or accent.

Practical example, if the web service to apply for ESTA (https://www.application-esta.co.uk/special-characters-and) would use above code instead of transforming umlauts correctly, the ESTA application would either be refused or the traveller will have problems with the American Border Control when entering the States.

Another example would be flight tickets. Assuming you have a flight ticket booking web application, the user provides his name with an accent and your implementation is just removing the accents and then using the airline's web service to book the ticket! Your customer may not be allowed to board since the name does not match to any part of his/her passport.

I fixed this by removing the settings.gradle from my module subproject. It's a Java Gradle project with it's own settings.gradle file that somehow it screws it up.

Radio inputs must be inside of a form for 'checked' to work.

Nice to see that it have been solved in the 2016 version, but for all of those that is not on that, here are two generalized and simplified versions of the methods above.

The XML-method is shorter, but of course requires the string to allow for the xml-trick (no 'bad' chars.)

XML-Method:

create function dbo.splitString(@input Varchar(max), @Splitter VarChar(99)) returns table as
Return
    SELECT Split.a.value('.', 'VARCHAR(max)') AS Data FROM
    ( SELECT CAST ('<M>' + REPLACE(@input, @Splitter, '</M><M>') + '</M>' AS XML) AS Data 
    ) AS A CROSS APPLY Data.nodes ('/M') AS Split(a); 

Recursive method:

create function dbo.splitString(@input Varchar(max), @Splitter Varchar(99)) returns table as
Return
  with tmp (DataItem, ix) as
   ( select @input  , CHARINDEX('',@Input)  --Recu. start, ignored val to get the types right
     union all
     select Substring(@input, ix+1,ix2-ix-1), ix2
     from (Select *, CHARINDEX(@Splitter,@Input+@Splitter,ix+1) ix2 from tmp) x where ix2<>0
   ) select DataItem from tmp where ix<>0

Function in action

Create table TEST_X (A int, CSV Varchar(100));
Insert into test_x select 1, 'A,B';
Insert into test_x select 2, 'C,D';

Select A,data from TEST_X x cross apply dbo.splitString(x.CSV,',') Y;

Drop table TEST_X

XML-METHOD 2: Unicode Friendly (Addition courtesy of Max Hodges) create function dbo.splitString(@input nVarchar(max), @Splitter nVarchar(99)) returns table as Return SELECT Split.a.value('.', 'NVARCHAR(max)') AS Data FROM ( SELECT CAST ('<M>' + REPLACE(@input, @Splitter, '</M><M>') + '</M>' AS XML) AS Data ) AS A CROSS APPLY Data.nodes ('/M') AS Split(a);

MySQL 5.7 and above saves root in MySQL log file.

Please try this:

sudo grep 'temporary password' /var/log/mysqld.log

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

"immutable" means you cannot change value. If you have an instance of String class, any method you call which seems to modify the value, will actually create another String.

String foo = "Hello";
foo.substring(3);
<-- foo here still has the same value "Hello"

To preserve changes you should do something like this foo = foo.sustring(3);

Immutable vs mutable can be funny when you work with collections. Think about what will happen if you use mutable object as a key for map and then change the value (tip: think about equals and hashCode).

There is more than one way to do it.

1). A long statement:

>>> def print_something():
         print 'This is a really long line,', \
               'but we can make it across multiple lines.'

2). Using parenthesis:

>>> def print_something():
        print ('Wow, this also works?',
               'I never knew!')

3). Using \ again:

>>> x = 10
>>> if x == 10 or x > 0 or \
       x < 100:
       print 'True'

Quoting PEP8:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately. The preferred place to break around a binary operator is after the operator, not before it.

Nothing should prevent you from just escaping every non-alphanumeric character:

usersString.replace(/(?=\W)/g, '\\');

You lose a certain degree of readability when doing re.toString() but you win a great deal of simplicity (and security).

According to ECMA-262, on the one hand, regular expression "syntax characters" are always non-alphanumeric, such that the result is secure, and special escape sequences (\d, \w, \n) are always alphanumeric such that no false control escapes will be produced.

If you're lazy enough to read chunks of post data. you could simply paste below lines to read json.

Below is for TypeScript similar can be done for JS as well.

app.ts

 import bodyParser from "body-parser";
 // support application/json type post data
 this.app.use(bodyParser.json());
 // support application/x-www-form-urlencoded post data
 this.app.use(bodyParser.urlencoded({ extended: false }));

In one of your any controller which receives POST call use as shown below

userController.ts

 public async POSTUser(_req: Request, _res: Response) {
   try {
          const onRecord = <UserModel>_req.body;
           /* Your business logic */
           _res.status(201).send("User Created");
        }
    else{
           _res.status(500).send("Server error");
           }        
   };

_req.body should be parsing you json data into your TS Model.

From man 7 gitrevisions:

HEAD names the commit on which you based the changes in the working tree. FETCH_HEAD records the branch which you fetched from a remote repository with your last git fetch invocation. ORIG_HEAD is created by commands that move your HEAD in a drastic way, to record the position of the HEAD before their operation, so that you can easily change the tip of the branch back to the state before you ran them. MERGE_HEAD records the commit(s) which you are merging into your branch when you run git merge. CHERRY_PICK_HEAD records the commit which you are cherry-picking when you run git cherry-pick.

Run it like this on the command line:

java -jar /path/to/your/jar/jarFile.jar

Here's one way:

Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}

Modified from here:MSDN OpenFileDialog.OpenFile

EDIT Here's another way more suited to your needs:

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
    OpenFileDialog theDialog = new OpenFileDialog();
    theDialog.Title = "Open Text File";
    theDialog.Filter = "TXT files|*.txt";
    theDialog.InitialDirectory = @"C:\";
    if (theDialog.ShowDialog() == DialogResult.OK)
    {
        string filename = theDialog.FileName;

        string[] filelines = File.ReadAllLines(filename);

        List<Employee> employeeList = new List<Employee>();
        int linesPerEmployee = 4;
        int currEmployeeLine = 0;
        //parse line by line into instance of employee class
        Employee employee = new Employee();
        for (int a = 0; a < filelines.Length; a++)
        {

            //check if to move to next employee
            if (a != 0 && a % linesPerEmployee == 0)
            {
                employeeList.Add(employee);
                employee = new Employee();
                currEmployeeLine = 1;
            }

            else
            {
                currEmployeeLine++;
            }
            switch (currEmployeeLine)
            {
                case 1:
                    employee.EmployeeNum = Convert.ToInt32(filelines[a].Trim());
                    break;
                case 2:
                    employee.Name = filelines[a].Trim();
                    break;
                case 3:
                    employee.Address = filelines[a].Trim();
                    break;
                case 4:
                    string[] splitLines = filelines[a].Split(' ');

                    employee.Wage = Convert.ToDouble(splitLines[0].Trim());
                    employee.Hours = Convert.ToDouble(splitLines[1].Trim());
                    break;


            }

        }
        //Test to see if it works
        foreach (Employee emp in employeeList)
        {
            MessageBox.Show(emp.EmployeeNum + Environment.NewLine +
                emp.Name + Environment.NewLine +
                emp.Address + Environment.NewLine +
                emp.Wage + Environment.NewLine +

In case, you are using PHP7 already, the formerly deprecated functions mysql_* were removed entirely, so you should update your code using the PDO-functions or mysqli_* functions instead.

If that's not possible, as a workaround, I created a small PHP include file, that recreates the old mysql_* functions with mysqli_*()-functions: fix_mysql.inc.php

The Simpler Way Of Converting A String To Integer In Groovy Is As Follows...

String aa="25"
int i= aa.toInteger()

Now "i" Holds The Integer Value.

form.MySelect.options[form.MySelect.selectedIndex].value

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

You could also use zip

import matplotlib.pyplot as plt

l = [(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08),
     (2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09),
     (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]

x, y = zip(*l)

plt.plot(x, y)

Named tuples were added in 2.6 for this purpose. Also see os.stat for a similar builtin example.

>>> import collections
>>> Point = collections.namedtuple('Point', ['x', 'y'])
>>> p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2

In recent versions of Python 3 (3.6+, I think), the new typing library got the NamedTuple class to make named tuples easier to create and more powerful. Inheriting from typing.NamedTuple lets you use docstrings, default values, and type annotations.

Example (From the docs):

class Employee(NamedTuple):  # inherit from typing.NamedTuple
    name: str
    id: int = 3  # default value

employee = Employee('Guido')
assert employee.id == 3

I have done this and it has worked.

Properties props = PropertiesLoaderUtils.loadAllProperties("my.properties");
PropertyPlaceholderConfigurer props2 = new PropertyPlaceholderConfigurer();
props2.setProperties(props);

That should work.

Just encase someone else ran into the issues I did I was using Response.End() an async trigger button

<asp:AsyncPostBackTrigger ControlID="btn_login" />

in an update panel. I switched to regular post back not the best but it worked.

<asp:PostBackTrigger ControlID="btn_login" />. 

Since I was only redirecting on the page this was a viable solution.

It depends on what best means for you. Productivity wise, don't reinvent the wheel and use Apache Commons. Which is here FileUtils.readFileToByteArray(File input).

Unfortunately, Javascript's cookie syntax is nowhere near as nice as that. In fact, in my opinion, it's one of the worst designed parts.

When you try to read document.cookie, you get a string containing all the cookies set. You have to parse the string, separating by the semicolon ; character. Rather than writing this yourself, there are plenty of versions available on the web. My favourite is the one at quirksmode.org. This gives you createCookie, readCookie and deleteCookie functions.

For anyone else who did all the advice but the problem still persists.

Check for stored procedure and view DEFINERS. Those definers may no longer exists.

My problem showed up when we changed the wildcard host (%) to IP specific, making the database more secure. Unfortunately there are some views that are still using 'user'@'%' even though 'user'@'172....' is technically correct.

Another approach is to use inplace editing inside Ruby (not from the command line):

#!/usr/bin/ruby

def inplace_edit(file, bak, &block)
    old_stdout = $stdout
    argf = ARGF.clone

    argf.argv.replace [file]
    argf.inplace_mode = bak
    argf.each_line do |line|
        yield line
    end
    argf.close

    $stdout = old_stdout
end

inplace_edit 'test.txt', '.bak' do |line|
    line = line.gsub(/search1/,"replace1")
    line = line.gsub(/search2/,"replace2")
    print line unless line.match(/something/)
end

If you don't want to create a backup then change '.bak' to ''.

Use git branch -a (both local and remote branches) or git branch -r (only remote branches) to see all the remotes and their branches. You can then do a git checkout -t remotes/repo/branch to the remote and create a local branch.

There is also a git-ls-remote command to see all the refs and tags for that remote.

<TextView
    android:layout_width="wrap_content"
    android:layout_height="32dp"
    android:background="@drawable/a"
    android:drawableLeft="@drawable/concern_black"
    android:gravity="center"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:drawablePadding="10dp"
    android:text="text"/>

note: layout_width needs to be wrap_content and use paddingLeft paddingRight drawablePadding to control gap. If you specify layout_width value is will has gap between icon and text, I think once give the layout_width a specify value, the padding will measure.

According to PEP8, long lines should be placed in parentheses. When using parentheses, the lines can be broken up without using backslashes. You should also try to put the line break after boolean operators.

Further to this, if you're using a code style check such as pycodestyle, the next logical line needs to have different indentation to your code block.

For example:

if (abcdefghijklmnopqrstuvwxyz > some_other_long_identifier and
        here_is_another_long_identifier != and_finally_another_long_name):
    # ... your code here ...
    pass

JDBC is a much lower-level (and older) specification than JPA. In it's bare essentials, JDBC is an API for interacting with a database using pure SQL - sending queries and retrieving results. It has no notion of objects or hierarchies. When using JDBC, it's up to you to translate a result set (essentially a row/column matrix of values from one or more database tables, returned by your SQL query) into Java objects.

Now, to understand and use JDBC it's essential that you have some understanding and working knowledge of SQL. With that also comes a required insight into what a relational database is, how you work with it and concepts such as tables, columns, keys and relationships. Unless you have at least a basic understanding of databases, SQL and data modelling you will not be able to make much use of JDBC since it's really only a thin abstraction on top of these things.

The question is how to create a new virtual environment in VSCode, that is why telling the following Anaconda solution might not the needed answer to the question. It is just relevant for Anaconda users.

Just create a venv using conda, see here. Afterwards open VSCode and left-click on the VSCode interpreter shown in VSCode at the bottom left:

Choose a virtual environment that pops up in a dropdown of the settings window, and you are done. Mind the answer of @RamiMa.

Best Solution: cut the export do get something like 00:05:03.22

ffmpeg -i input 2>&1 | grep Duration | cut -c 13-23

if(newStr4.startsWith("Mon") || newStr4.startsWith("Tues") || newStr4.startsWith("Weds") .. etc)

You need to include the whole str.startsWith(otherStr) for each item, since || only works with boolean expressions (true or false).

There are other options if you have a lot of things to check, like regular expressions, but they tend to be slower and more complicated regular expressions are generally harder to read.

An example regular expression for detecting day name abbreviations would be:

if(Pattern.matches("Mon|Tues|Wed|Thurs|Fri", stringToCheck)) {

The following document provides some information on porting code from UNIX to Win32: https://msdn.microsoft.com/en-us/library/y23kc048.aspx

Among other things, it indicates that the process model is quite different between the two systems and recommends consideration of CreateProcess and CreateThread where fork()-like behavior is required.

This is correct.

A[] a = new A[4];

...creates 4 A references, similar to doing this:

A a1;
A a2;
A a3;
A a4;

Now you couldn't do a1.someMethod() without allocating a1 like this:

a1 = new A();

Similarly, with the array you need to do this:

a[0] = new A();

...before using it.

When you access resultFrame through document.all it only pulls it as an HTML element, not a window frame. You get the same issue if you have a frame fire an event using a "this" self-reference.

Replace:

document.all.resultFrame.Reset();

With:

window.frames.resultFrame.Reset();

Or:

document.all.resultFrame.contentWindow.Reset();

Yes you can. In c++, class and struct are kind of similar. We can define not only structure inside a class, but also a class inside one. It is called inner class.

As an example I am adding a simple Trie class.

class Trie {
private:
    struct node{
        node* alp[26];
        bool isend;
    };
    node* root;
    node* createNode(){
        node* newnode=new node();
        for(int i=0; i<26; i++){
            newnode->alp[i]=nullptr;
        }
        newnode->isend=false;
        return newnode;
    }
public:
    /** Initialize your data structure here. */
    Trie() {
        root=createNode();
    }

    /** Inserts a word into the trie. */
    void insert(string word) {
        node* head=root;
        for(int i=0; i<word.length(); i++){
            if(head->alp[int(word[i]-'a')]==nullptr){
                node* newnode=createNode();
                head->alp[int(word[i]-'a')]=newnode;
            }
            head=head->alp[int(word[i]-'a')];
        }
        head->isend=true;
    }

    /** Returns if the word is in the trie. */
    bool search(string word) {
        node* head=root;
        for(int i=0; i<word.length(); i++){
            if(head->alp[int(word[i]-'a')]==nullptr){
                return false;
            }
            head=head->alp[int(word[i]-'a')];
        }
        if(head->isend){return true;}
        return false;
    }

    /** Returns if there is any word in the trie that starts with the given prefix. */
    bool startsWith(string prefix) {
        node* head=root;
        for(int i=0; i<prefix.length(); i++){
            if(head->alp[int(prefix[i]-'a')]==nullptr){
                return false;
            }
            head=head->alp[int(prefix[i]-'a')];
        }
        return true;
    }
};

/**
 * Your Trie object will be instantiated and called as such:
 * Trie* obj = new Trie();
 * obj->insert(word);
 * bool param_2 = obj->search(word);
 * bool param_3 = obj->startsWith(prefix);
 */

You can specify the whole day by doing a range, like so:

WHERE bk_date >= TO_DATE('2012-03-18', 'YYYY-MM-DD')
AND bk_date <  TO_DATE('2012-03-19', 'YYYY-MM-DD')

More simply you can use TRUNC:

WHERE TRUNC(bk_date) = TO_DATE('2012-03-18', 'YYYY-MM-DD')

TRUNC without parameter removes hours, minutes and seconds from a DATE.

The filter function wasn't working for me at all; maybe the more recent version of jquery doesn't perform as the version used in above code. Regardless; I used:

    var black = $('.black');
    var white = $('.white');

The selector will find every element classed under black or white. Button functions stay as stated above:

    $('#showBlackButton').click(function() {
           black.show();
           white.hide();
    });

    $('#showWhiteButton').click(function() {
           white.show();
           black.hide();
    });

Also try System.currentTimeMillis()

The question has been asked on serverfault too.

You may want to take a look at this article which explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.

The simplest way to fix this is to use the Barracuda file format with InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.

The method that worked for the OP there was:

1. Add the following to the my.cnf file under [mysqld] section.

   innodb_file_per_table=1
   innodb_file_format = Barracuda
   

2. ALTER the table to use ROW_FORMAT=COMPRESSED.

   ALTER TABLE nombre_tabla
       ENGINE=InnoDB
       ROW_FORMAT=COMPRESSED 
       KEY_BLOCK_SIZE=8;
   

There is a possibility that the above still does not resolve your issues. It is a known (and verified) bug with the InnoDB engine, and a temporary fix for now is to fallback to MyISAM engine as temporary storage. So, in your my.cnf file:

internal_tmp_disk_storage_engine=MyISAM

finally solved my problem.

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.

None of solutions on this page works correctly and universally for all levels and long (wrapped) paragraphs. It’s really tricky to achieve a consistent indentation due to variable size of marker (1., 1.2, 1.10, 1.10.5, …); it can’t be just “faked,” not even with a precomputed margin/padding for each possible indentation level.

I finally figured out a solution that actually works and doesn’t need any JavaScript.

It’s tested on Firefox 32, Chromium 37, IE 9 and Android Browser. Doesn't work on IE 7 and previous.

CSS:

ol {
  list-style-type: none;
  counter-reset: item;
  margin: 0;
  padding: 0;
}

ol > li {
  display: table;
  counter-increment: item;
  margin-bottom: 0.6em;
}

ol > li:before {
  content: counters(item, ".") ". ";
  display: table-cell;
  padding-right: 0.6em;    
}

li ol > li {
  margin: 0;
}

li ol > li:before {
  content: counters(item, ".") " ";
}

Example:

Try it on JSFiddle, fork it on Gist.

Just in case someone else stumbles on this. I was running someone else's code - make sure they are not handling the signal, so they can gracefully exit. I commented out the handling, and got the core dump.

If you are developing and testing in Firefox, there's a plug-in called "ReloadEvery" is available, which allows you to reload the page at the specified intervals.

You can include this directly in your buttun. It works very well. I hope it'll be useful for you. onclick="setTimeout('location.href = ../../dashboard.xhtml;', 7000);"

select @EmpID = ID from dbo.Employee

Or

set @EmpID =(select id from dbo.Employee)

Note that the select query might return more than one value or rows. so you can write a select query that must return one row.

If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable

DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..

As table type variable do not exist in Oracle and others, you would have to define it:

DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;

-- Then to declare a TABLE variable of this type: variable_name type_name;

-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text';

-- Where 'n' is the index value

Try DesrLabel.Content. Its the WPF way.

Concatenate Strings

Concatenating any two strings in C can be done in atleast 3 ways :-

1) By copying string 2 to the end of string 1

#include <stdio.h>
#include <string.h>
#define MAX 100
int main()
{
  char str1[MAX],str2[MAX];
  int i,j=0;
  printf("Input string 1: ");
  gets(str1);
  printf("\nInput string 2: ");
  gets(str2);
  for(i=strlen(str1);str2[j]!='\0';i++)  //Copying string 2 to the end of string 1
  {
     str1[i]=str2[j];
     j++;
  }
  str1[i]='\0';
  printf("\nConcatenated string: ");
  puts(str1);
  return 0;
}

2) By copying string 1 and string 2 to string 3

#include <stdio.h>
#include <string.h>
#define MAX 100
int main()
{
  char str1[MAX],str2[MAX],str3[MAX];
  int i,j=0,count=0;
  printf("Input string 1: ");
  gets(str1);
  printf("\nInput string 2: ");
  gets(str2);
  for(i=0;str1[i]!='\0';i++)          //Copying string 1 to string 3
  {
    str3[i]=str1[i];
    count++;
  }
  for(i=count;str2[j]!='\0';i++)     //Copying string 2 to the end of string 3
  {
    str3[i]=str2[j];
    j++;
  }
  str3[i]='\0';
  printf("\nConcatenated string : ");
  puts(str3);
  return 0;
}

3) By using strcat() function

#include <stdio.h>
#include <string.h>
#define MAX 100
int main()
{
  char str1[MAX],str2[MAX];
  printf("Input string 1: ");
  gets(str1);
  printf("\nInput string 2: ");
  gets(str2);
  strcat(str1,str2);                    //strcat() function
  printf("\nConcatenated string : ");
  puts(str1);

For those who struggled the same as me with laravel artisan console command that makes a lot of requests to same wsdl of external soap server and then after some time fails with Could not connect to host error.

The problem was because I was creating new SoapClient instance each time before request was made. Do not do that. Create it once and make each request from the same client.

Hope it helps.

For interactive work, Matplotlib is the mature standard. It provides an OO-style API as well as a Matlab-style interactive API.

Chaco is a more modern plotting library from the folks at Enthought. It uses Enthought's Kiva vector drawing library and currently works only with Wx and Qt with OpenGL on the way (Matplotlib has backends for Tk, Qt, Wx, Cocoa, and many image types such as PDF, EPS, PNG, etc.). The main advantages of Chaco are its speed relative to Matplotlib and its integration with Enthought's Traits API for interactive applications.

Like @flodel wrote: This converts your dataframe into a list that has the same number of elements as number of rows in dataframe:

NewList <- split(df, f = seq(nrow(df)))

You can additionaly add a function to select only those columns that are not NA in each element of the list:

NewList2 <- lapply(NewList, function(x) x[,!is.na(x)])

The answer by Nils describes how to convert objects to maps, which I found very useful. However, the OP was also wondering where this information is in the MDN docs. While it may not have been there when the question was originally asked, it is now on the MDN page for Object.entries() under the heading Converting an Object to a Map which states:

Converting an Object to a Map

The new Map() constructor accepts an iterable of entries. With Object.entries, you can easily convert from Object to Map:

const obj = { foo: 'bar', baz: 42 }; 
const map = new Map(Object.entries(obj));
console.log(map); // Map { foo: "bar", baz: 42 }

#!/usr/bin/expect -f
spawn scp -r BASE.zip [email protected]:/tmp
expect "password:"
send "wifinetworks\r"
expect "*\r"
expect "\r"

What worked for me, is registering it on the Page while specifying the type as that of the UpdatePanel, like so:

ScriptManager.RegisterClientScriptBlock(this.Page, typeof(UpdatePanel) Guid.NewGuid().ToString(), myScript, true);

You can convert it to a string, and then to an int:

print(int("".join(str(x) for x in [7,7,7,7])))

The general consensus answer above seems to have have a compatibility issue with CORS support. In order to use the HttpContext.Current.User.Identity.Name attribute you must disable anonymous authentication in order to force Windows authentication to provide the authenticated user information. Unfortunately, I believe you must have anonymous authentication enabled in order to process the pre-flight OPTIONS request in a CORS scenario.

You can get around this by leaving anonymous authentication enabled and using the HttpContext.Current.Request.LogonUserIdentity attribute instead. This will return the authenticated user information (assuming you are in an intranet scenario) even with anonymous authentication enabled. The attribute returns a WindowsUser data structure and both are defined in the System.Web namespace

        using System.Web;
        WindowsIdentity user;
        user  = HttpContext.Current.Request.LogonUserIdentity;

Set the tagName as an explicit attribute:

for(var i=0,els=document.querySelectorAll('*'); i<els.length;
          els[i].setAttribute('tagName',els[i++].tagName) );

I needed this myself, for an XML Document, with Nested Tags ending in _Sequence. See JaredMcAteer answer for more details.

document.querySelectorAll('[tagName$="_Sequence"]')

I didn't say it would be pretty :) PS: I would recommend to use tag_name over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.

Many ways to do:

html,body{
    height:297mm;
    width:210mm;
}


html,body{
    height:29.7cm;
    width:21cm;
}

html,body{
    height: 842px;
    width: 595px;
}

git branch --set-upstream master origin/master

This will add the following info to your config file:

[branch "master"]
    remote = origin
    merge = refs/heads/master

If you have branch.autosetuprebase = always then it will also add:

    rebase = true

I had exactly the same problem, my solution was to use module definition file (.def) instead of __declspec(dllexport) to define exports(http://msdn.microsoft.com/en-us/library/d91k01sh.aspx). I have no idea why this works, but it does

You can now use Cache.delete()

Example:

let id = "your-cache-id";
// you can find the id by going to 
// application>storage>cache storage 
// (minus the page url at the end)
// in your chrome developer console 

caches.open(id)
.then(cache => cache.keys()
  .then(keys => {
    for (let key of keys) {
      cache.delete(key)
    }
  }));

Works on Chrome 40+, Firefox 39+, Opera 27+ and Edge.

There are many PHP debugging techniques that can save you countless hours when coding. An effective but basic debugging technique is to simply turn on error reporting. Another slightly more advanced technique involves using print statements, which can help pinpoint more elusive bugs by displaying what is actually going onto the screen. PHPeclipse is an Eclipse plug-in that can highlight common syntax errors and can be used in conjunction with a debugger to set breakpoints.

display_errors = Off
error_reporting = E_ALL 
display_errors = On

and also used

error_log();
console_log();

You need a Python DictReader class. More help can be found from here

import csv

with open('file_name.csv', 'rt') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print row

It looks like you're writing PHP, in which case you want:

<?
$arr=array('us'=>'United', 'ca'=>'canada');
$key='ca';
echo $arr[$key];
?>

Notice that the ('us'=>'United', 'ca'=>'canada') needs to be a parameter to the array function in PHP.

Most programming languages that support associative arrays or dictionaries use arr['key'] to retrieve the item specified by 'key'

For instance:

Ruby

ruby-1.9.1-p378 > h = {'us' => 'USA', 'ca' => 'Canada' }
 => {"us"=>"USA", "ca"=>"Canada"} 
ruby-1.9.1-p378 > h['ca']
 => "Canada" 

Python

>>> h = {'us':'USA', 'ca':'Canada'}
>>> h['ca']
'Canada'

C#

class P
{
    static void Main()
    {
        var d = new System.Collections.Generic.Dictionary<string, string> { {"us", "USA"}, {"ca", "Canada"}};
        System.Console.WriteLine(d["ca"]);
    }
}

Lua

t = {us='USA', ca='Canada'}
print(t['ca'])
print(t.ca) -- Lua's a little different with tables

From http://pyyaml.org/wiki/PyYAMLDocumentation:

add_path_resolver(tag, path, kind) adds a path-based implicit tag resolver. A path is a list of keys that form a path to a node in the representation graph. Paths elements can be string values, integers, or None. The kind of a node can be str, list, dict, or None.

#!/usr/bin/env python
import yaml

class Person(yaml.YAMLObject):
  yaml_tag = '!person'

  def __init__(self, name):
    self.name = name

yaml.add_path_resolver('!person', ['Person'], dict)

data = yaml.load("""
Person:
  name: XYZ
""")

print data
# {'Person': <__main__.Person object at 0x7f2b251ceb10>}

print data['Person'].name
# XYZ

getActivity().getFragmentManager() This worked or me.

Use g++

g++ -o hi hi.cpp

g++ is for C++, gcc is for C although with the -libstdc++ you can compile c++ most people don't do this.

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

Just set the TextBox.PasswordChar property to '*'.

Step 1: Install the dependencies

sudo apt-get install build-dep python-psycopg2

Step 2: Run this command in your virtualenv

pip install psycopg2

After reading your question, I would say, generate special token to do request required. This token will live in specific time (lets say in one day).

Here is an example from to generate authentication token:

(day * 10) + (month * 100) + (year (last 2 digits) * 1000)

for example: 3 June 2011

(3 * 10) + (6 * 100) + (11 * 1000) = 
30 + 600 + 11000 = 11630

then concatenate with user password, example "my4wesomeP4ssword!"

11630my4wesomeP4ssword!

Then do MD5 of that string:

05a9d022d621b64096160683f3afe804

When do you call a request, always use this token,

https://mywebservice.com/?token=05a9d022d621b64096160683f3afe804&op=getdata

This token is always unique everyday, so I guess this kind of protection is more than sufficient to always protect ur service.

Hope helps

You can also try this for the double quotes:

JSON.stringify(sDemoString).slice(1, -1);
JSON.stringify('my string with "quotes"').slice(1, -1);

Background color of views (navigator, console, tasks etc) is set according to the desktop (system) settings. On Linux/GNome I changed System/Preferences/Appeareance to change this color.

Editor colors are set chaotically by different editors, search for background in eclipse preferences to find different options. One easy way to get beautiful dark (and not only dark) themes is to install Afae plugin, and then pick theme within its preferences (twilight theme is beautiful, for example) - again, eclipse prefs, Afae group. Of course this applies only when you edit with Afae.

In addition to other answers, there is sometimes the scenario where you wish to have private modules available in a team context.

Both Github and Bitbucket support the concept of generating a team API Key. This API key can be used as the password to perform API requests as this team.

In your private npm modules add

"private": true 

to your package.json

Then to reference the private module in another module, use this in your package.json

    {
        "name": "myapp",
        "dependencies": {
            "private-repo":
"git+https://myteamname:[email protected]/myprivate.git",
        }
    }

where team name = myteamname, and API Key = aQqtcplwFzlumj0mIDdRGCbsAq5d6Xg4

Here I reference a bitbucket repo, but it is almost identical using github too.

Finally, as an alternative, if you really don't mind paying $7 per month (as of writing) then you can now have private NPM modules out of the box.

This works in Mac as well you can use

df= pd.read_csv('Region_count.csv', encoding ='latin1')

If after you confirm your Bundle ID's match across App Store Connect, Apple Developer Portal, and Xcode and you are still having issues try this:

Remove the Apple ID associated with the Bundle ID you're experiencing issues with from your Accounts list in Xcode (Menu Bar -> Xcode -> Preferences -> Accounts). Then, add the Apple ID back to the Accounts list in Xcode.

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

For pre API 8 i solved the problem using a boolean flag, a dismiss listener and calling dialog.show again if in case the content of the editText wasn´t correct. Like this:

case ADD_CLIENT:
        LayoutInflater factoryClient = LayoutInflater.from(this);
        final View EntryViewClient = factoryClient.inflate(
                R.layout.alert_dialog_add_client, null);

        EditText ClientText = (EditText) EntryViewClient
                .findViewById(R.id.client_edit);

        AlertDialog.Builder builderClient = new AlertDialog.Builder(this);
        builderClient
                .setTitle(R.string.alert_dialog_client)
                .setCancelable(false)
                .setView(EntryViewClient)
                .setPositiveButton("Save",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                EditText newClient = (EditText) EntryViewClient
                                        .findViewById(R.id.client_edit);
                                String newClientString = newClient
                                        .getText().toString();
                                if (checkForEmptyFields(newClientString)) {
                                    //If field is empty show toast and set error flag to true;
                                    Toast.makeText(getApplicationContext(),
                                            "Fields cant be empty",
                                            Toast.LENGTH_SHORT).show();
                                    add_client_error = true;
                                } else {
                                    //Here save the info and set the error flag to false
                                    add_client_error = false;
                                }
                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int id) {
                                add_client_error = false;
                                dialog.cancel();
                            }
                        });
        final AlertDialog alertClient = builderClient.create();
        alertClient.show();

        alertClient
                .setOnDismissListener(new DialogInterface.OnDismissListener() {

                    @Override
                    public void onDismiss(DialogInterface dialog) {
                        //If the error flag was set to true then show the dialog again
                        if (add_client_error == true) {
                            alertClient.show();
                        } else {
                            return;
                        }

                    }
                });
        return true;

Since Python 2.7 you can use context manager to get ahold of the actual Exception object thrown:

import unittest

def broken_function():
    raise Exception('This is broken')

class MyTestCase(unittest.TestCase):
    def test(self):
        with self.assertRaises(Exception) as context:
            broken_function()

        self.assertTrue('This is broken' in context.exception)

if __name__ == '__main__':
    unittest.main()

http://docs.python.org/dev/library/unittest.html#unittest.TestCase.assertRaises

In Python 3.5, you have to wrap context.exception in str, otherwise you'll get a TypeError

self.assertTrue('This is broken' in str(context.exception))

You can check this like below :

if varDate = "#01/01/0001#" then
       '  blank date. do something.
else
       ' Date is not blank. Do some other thing
end if

Check in your project that Pods are maybe not being pushed to Git. So it's obvious that compile will break since it cannot find the Pods directory

 diff "${PODS_ROOT}/../../Podfile.lock" "${PODS_ROOT}/Manifest.lock" > /dev/null

I solved this by issuing pod install in the Terminal after navigating to my project's directory.

Indeed, I had an error cannot find pod command which meant that cocoapods were not installed. This is fixed via gem install cocoapods. If you get any dependency error, just install each command that is reported missing. In my case I had to update Ruby and after that cocoapods were installed properly and I was able to use the command pod install.

PS. If you have Pods directory, try pod update. Maybe your library needs updating.

jQuery

jQuery makes ridiculously long JavaScript commands like getElementByHerpDerp shorter and cross-browser.

AngularJS

AngularJS allows you to make your own HTML tags/attributes that do things which work well with dynamic web applications (since HTML was designed for static pages).

Edit:

Saying "I have a jQuery background how do I think in AngularJS?" is like saying "I have an HTML background how do I think in JavaScript?" The fact that you're asking the question shows you most likely don't understand the fundamental purposes of these two resources. This is why I chose to answer the question by simply pointing out the fundamental difference rather than going through the list saying "AngularJS makes use of directives whereas jQuery uses CSS selectors to make a jQuery object which does this and that etc....". This question does not require a lengthy answer.

jQuery is a way to make programming JavaScript in the browser easier. Shorter, cross-browser commands, etc.

AngularJS extends HTML, so you don't have to put <div> all over the place just to make an application. It makes HTML actually work for applications rather than what it was designed for, which is static, educational web pages. It accomplishes this in a roundabout way using JavaScript, but fundamentally it is an extension of HTML, not JavaScript.

user3919888 pointed me in the right direction, but I needed to run Update-Package -reinstall Microsoft.AspNet.WebApi.Client in the Package-Manager console. Basic install by itself does not recognize the problem but does recognize that the package is already installed and does not overwrite it.

I'm posting this answer because this happens so infrequently that I end up googling and reaching this page before I remember what I did last time.

I know this topic is a bit old, but I think I did something that may be useful for someone, so I'm posting it.

I compiled suggestions from this thread's answers into a procedure:

CREATE OR REPLACE PROCEDURE create_table_if_doesnt_exist(
  p_table_name VARCHAR2,
  create_table_query VARCHAR2
) AUTHID CURRENT_USER IS
  n NUMBER;
BEGIN
  SELECT COUNT(*) INTO n FROM user_tables WHERE table_name = UPPER(p_table_name);
  IF (n = 0) THEN
    EXECUTE IMMEDIATE create_table_query;
  END IF;
END;

You can then use it in a following way:

call create_table_if_doesnt_exist('my_table', 'CREATE TABLE my_table (
        id NUMBER(19) NOT NULL PRIMARY KEY,
        text VARCHAR2(4000),
        modified_time TIMESTAMP
  )'
);

I know that it's kinda redundant to pass table name twice, but I think that's the easiest here.

Hope somebody finds above useful :-).

Almost there. In your predicate, you want a relative path, so change

./book[/author/name = 'John'] 

to either

./book[author/name = 'John'] 

or

./book[./author/name = 'John'] 

and you will match your element. Your current predicate goes back to the root of the document to look for an author.

Remove the data from the adapter and call adapter.notifyDataSetChanged();

You can loop through variable with list of directories:

- name: Copy files from several directories
  copy:
    src: "{{ item }}"
    dest: "/etc/fooapp/"
    owner: root
    mode: "0600"
  loop: "{{ files }}"
  vars:
    files:
      - "dir1/"
      - "dir2/"

Just because everyone was so helpful I'll just add a modification to Zelazny7 and Daniele's beautiful solutions. This one is for python 2.7, with tabs to make it more readable:

def get_code(tree, feature_names, tabdepth=0):
    left      = tree.tree_.children_left
    right     = tree.tree_.children_right
    threshold = tree.tree_.threshold
    features  = [feature_names[i] for i in tree.tree_.feature]
    value = tree.tree_.value

    def recurse(left, right, threshold, features, node, tabdepth=0):
            if (threshold[node] != -2):
                    print '\t' * tabdepth,
                    print "if ( " + features[node] + " <= " + str(threshold[node]) + " ) {"
                    if left[node] != -1:
                            recurse (left, right, threshold, features,left[node], tabdepth+1)
                    print '\t' * tabdepth,
                    print "} else {"
                    if right[node] != -1:
                            recurse (left, right, threshold, features,right[node], tabdepth+1)
                    print '\t' * tabdepth,
                    print "}"
            else:
                    print '\t' * tabdepth,
                    print "return " + str(value[node])

    recurse(left, right, threshold, features, 0)

The 1./2 syntax works because 1. is a float. It's the same as 1.0. The dot isn't a special operator that makes something a float. So, you need to either turn one (or both) of the operands into floats some other way -- for example by using float() on them, or by changing however they were calculated to use floats -- or turn on "true division", by using from __future__ import division at the top of the module.

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Edit: I misunderstood your question, I thought you were asking how to pad with spaces.

What you are asking is not possible using the string.Format alignment component; string.Format always pads with whitespace. See the Alignment Component section of MSDN: Composite Formatting.

According to Reflector, this is the code that runs inside StringBuilder.AppendFormat(IFormatProvider, string, object[]) which is called by string.Format:

int repeatCount = num6 - str2.Length;
if (!flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}
this.Append(str2);
if (flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}

As you can see, blanks are hard coded to be filled with whitespace.

I've had this error as a result of trying to use a cloned VM that had the same SID as the domain. The two options to fix it were: sysprep (or rebuild) the database server OR dcpromo the DC down and back up to change the domain SID.

I like to use the handy process outlined here to build connection strings using a .udl file. This allows you to test them from within the udl file to ensure that you can connect before you run any code.

Hope that helps.

This was working for me so Try This: $ad->getcodes()->distinct('pid')->count()

this is you need and all people

   string date  = textBox1.Text;

        DateTime date2 = Convert.ToDateTime(date);
        var date3 = date2.Date;
        var D = date3.Day;
      var M =  date3.Month;         
      var y = date3.Year;
      string monthStr = M.ToString("00");
      string date4 = D.ToString() + "/" + monthStr.ToString() + "/" + y.ToString();


      textBox1.Text = date4;

Following Markus's answer, in newer versions of JS (ES6 I think) you can create a 'struct' factory more simply using Arrow Functions and Rest Parameter like so:

const Struct = (...keys) => ((...v) => keys.reduce((o, k, i) => {o[k] = v[i]; return o} , {}))
const Item = Struct('id', 'speaker', 'country')
var myItems = [
    Item(1, 'john', 'au'),
    Item(2, 'mary', 'us')
];

console.log(myItems);
console.log(myItems[0].id);
console.log(myItems[0].speaker);
console.log(myItems[0].country);

The result of running this is:

[ { id: 1, speaker: 'john', country: 'au' },
  { id: 2, speaker: 'mary', country: 'us' } ]
1
john
au

You can make it look similar to Python's namedtuple:

const NamedStruct = (name, ...keys) => ((...v) => keys.reduce((o, k, i) => {o[k] = v[i]; return o} , {_name: name}))
const Item = NamedStruct('Item', 'id', 'speaker', 'country')
var myItems = [
    Item(1, 'john', 'au'),
    Item(2, 'mary', 'us')
];

console.log(myItems);
console.log(myItems[0].id);
console.log(myItems[0].speaker);
console.log(myItems[0].country);

And the results:

[ { _name: 'Item', id: 1, speaker: 'john', country: 'au' },
  { _name: 'Item', id: 2, speaker: 'mary', country: 'us' } ]
1
john
au

select E1.EmpId,E1.Name,E2.Name as Manager from Employee E1 left join Employee E2 on  E1.ManagerID = E2.EmpId

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

Use substring function
Check this out http://jsfiddle.net/kuc5as83/

var string = "1234567890"
var substr=string.substr(-8);
document.write(substr);

Output >> 34567890

substr(-8) will keep last 8 chars

var substr=string.substr(8);
document.write(substr);

Output >> 90

substr(8) will keep last 2 chars

var substr=string.substr(0, 8);
document.write(substr);

Output >> 12345678

substr(0, 8) will keep first 8 chars

Check this out string.substr(start,length)

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

Just wanted to add another simple way someone can sort the the WPF ListView

void SortListView(ListView listView)
{
    IEnumerable listView_items = listView.Items.SourceCollection;
    List<MY_ITEM_CLASS> listView_items_to_list = listView_items.Cast<MY_ITEM_CLASS>().ToList();

    Comparer<MY_ITEM_CLASS> scoreComparer = Comparer<MY_ITEM_CLASS>.Create((first, second) => first.COLUMN_NAME.CompareTo(second.COLUMN_NAME));

    listView_items_to_list.Sort(scoreComparer);
    listView.ItemsSource = null;
    listView.Items.Clear();
    listView.ItemsSource = listView_items_to_list;
}

In Python 3, print is a function, you need to call it like print("hello world").

Update March 2017:

URL.searchParams support has officially landed in Chrome 51, but other browsers still require a polyfill.

The official way to work with query parameters is just to add them onto the URL. From the spec, this is an example:

var url = new URL("https://geo.example.org/api"),
    params = {lat:35.696233, long:139.570431}
Object.keys(params).forEach(key => url.searchParams.append(key, params[key]))
fetch(url).then(/* … */)

However, I'm not sure Chrome supports the searchParams property of a URL (at the time of writing) so you might want to either use a third party library or roll-your-own solution.

Update April 2018:

With the use of URLSearchParams constructor you could assign a 2D array or a object and just assign that to the url.search instead of looping over all keys and append them

var url = new URL('https://sl.se')

var params = {lat:35.696233, long:139.570431} // or:
var params = [['lat', '35.696233'], ['long', '139.570431']]

url.search = new URLSearchParams(params).toString();

fetch(url)

Sidenote: URLSearchParams is also available in NodeJS

const { URL, URLSearchParams } = require('url');

The difference is that an EXE has an entry point, a "main" method that will run on execution.

The code within a DLL needs to be called from another application.

In terminal run this command in the folder where the systlesheets are:

sass --watch style.scss:style.css 

Source:

http://sass-lang.com/

When ever it notices a change in the .scss file it will update your .css

This only works when your .scss is on your local machine. Try copying the code to a file and running it locally.

HashMap<String, String> meMap=new HashMap<String, String>();
meMap.put("Color1","Red");
meMap.put("Color2","Blue");
meMap.put("Color3","Green");
meMap.put("Color4","White");
Iterator iterator = meMap.keySet().iterator();
while( iterator. hasNext() ){
    Toast.makeText(getBaseContext(), meMap.get(iterator.next().toString()), 
    Toast.LENGTH_SHORT).show();
}

Use this code, was better solution for me.

public static boolean containsWhiteSpace(String line){
    boolean space= false; 
    if(line != null){


        for(int i = 0; i < line.length(); i++){

            if(line.charAt(i) == ' '){
            space= true;
            }

        }
    }
    return space;
}

Java strings are immutable. But you has many options:

You can use:

The StringBuilder class instead, so you can remove everything you want and control your string.

The replace method.

And you can actually use a loop £:

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

document.getElementById('TextBoxID').readOnly = true;    //to enable readonly


document.getElementById('TextBoxID').readOnly = false;   //to  disable readonly

You can solve it very simple way just invoking the input. However, if you press Enter then the console will disapper again. Simply use this Console.ReadLine(); or Console.Read();

Using Fetch and async function

const logFileText = async file => {
    const response = await fetch(file)
    const text = await response.text()
    console.log(text)
}

logFileText('file.txt')

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

Setting the $PYTHONPATH environment variable does not seem to affect the Spyder IDE's iPython terminals on a Mac. However, Spyder's application menu contains a "PYTHONPATH manager." Adding my path here solved my problem. The "PYTHONPATH manager" is also persistent across application restarts.

This is specific to a Mac, because setting the PYTHONPATH environment variable on my Windows PC gives the expected behavior (modules are found) without using the PYTHONPATH manager in Spyder.

Another way to add a default namespace to an XML Document before feeding it to JAXB is to use JDom:

1. Parse XML to a Document
2. Iterate through and set namespace on all Elements
3. Unmarshall using a JDOMSource

Like this:

public class XMLObjectFactory {
    private static Namespace DEFAULT_NS = Namespace.getNamespace("http://tempuri.org/");

    public static Object createObject(InputStream in) {
        try {
            SAXBuilder sb = new SAXBuilder(false);
            Document doc = sb.build(in);
            setNamespace(doc.getRootElement(), DEFAULT_NS, true);
            Source src = new JDOMSource(doc);
            JAXBContext context = JAXBContext.newInstance("org.tempuri");
            Unmarshaller unmarshaller = context.createUnmarshaller();
            JAXBElement root = unmarshaller.unmarshal(src);
            return root.getValue();
        } catch (Exception e) {
            throw new RuntimeException("Failed to create Object", e);
        }
    }

    private static void setNamespace(Element elem, Namespace ns, boolean recurse) {
        elem.setNamespace(ns);
        if (recurse) {
            for (Object o : elem.getChildren()) {
                setNamespace((Element) o, ns, recurse);
            }
        }
    }

If you need to join and filter on something, that can be done outside of the join. Filter can be done after creating the collection.

In this case if I do this in the join condition I reduce the rows that are returned.

Ternary condition is used (= n == null ? "__" : n.MonDayNote,)

• If the object is null (so no match), then return what is after the ?. __, in this case.

• Else, return what is after the :, n.MonDayNote.

Thanks to the other contributors that is where I started with my own issue.

If you have multiple elements with same id or same name, just assign same class to those multiple elements and access them by index & perform your required operation.

  <div>
        <span id="a" class="demo">1</span>
        <span id="a" class="demo">2</span>
        <span>3</span>
    </div>

JQ:

$($(".demo")[0]).val("First span");
$($(".demo")[1]).val("Second span");

I propose use StringBuilder

string s1 = "'99024','99050','99070','99143','99173','99191','99201','99202','99203','99204','99211','99212','99213','99214','99215','99217','99218','99219','99221','99222','99231','99232','99238','99239','99356','99357','99371','99374','99381','99382','99383','99384','99385','99386','99391','99392'";

var stringBuilder = new StringBuilder();           

foreach (var s in s1.Split(','))
{
    stringBuilder.Append(s).Append(",").AppendLine();
}
Console.WriteLine(stringBuilder);

I know, I am late to this party, however I think it could be helpful for others.

Already posted answers are for csv and other one is by Interop dll where you need to install excel over the server, every approach has its own pros and cons. Here is an option which will give you

1. Perfect excel output [not csv]
2. With perfect excel and your data type match
3. Without excel installation
4. Pass list and get Excel output :)

you can achieve this by using NPOI DLL, available for both .net as well as for .net core

Steps :

1. Import NPOI DLL
2. Add Section 1 and 2 code provided below
3. Good to go

Section 1

This code performs below task :

1. Creating New Excel object - _workbook = new XSSFWorkbook();
2. Creating New Excel Sheet object - _sheet =_workbook.CreateSheet(_sheetName);
3. Invokes WriteData() - explained later Finally, creating and
4. returning MemoryStream object

Now you just need to call WriteData() function by passing your list, and it will provide you your excel.

I have tested it in WEB API and WEB API Core, works like a charm.

I think it is worth considering that you can get the requested info with just a single API call to the standard library...

new Date().toLocaleString( 'sv', { timeZoneName: 'short' } );

// produces "2019-10-30 15:33:47 GMT-4"

You would have to do text swapping if you want to add the 'T' delimiter, remove the 'GMT-', or append the ':00' to the end.

But then you can easily play with the other options if you want to eg. use 12h time or omit the seconds etc.

Note that I'm using Sweden as locale because it is one of the countries that uses ISO 8601 format. I think most of the ISO countries use this 'GMT-4' format for the timezone offset other then Canada which uses the time zone abbreviation eg. "EDT" for eastern-daylight-time.

You can get the same thing from the newer standard i18n function "Intl.DateTimeFormat()" but you have to tell it to include the time via the options or it will just give date.

I don't believe you can hack via the URL. Someone could try to inject code into your application if you are passing parameters (either GET or POST) into your app so your avoidance is going to be very similar to what you'd do for a local application.

Make sure you aren't adding parameters to SQL or other script executions that were passed into the code from the browser without making sure the strings don't contain any script language. Search the next for details about injection attacks for the development platform you are working with, that should yield lots of good advice and examples.

.net core

using System.Text.Json;

To serialize

var jsonStr = JsonSerializer.Serialize(MyObject)

Deserialize

var weatherForecast = JsonSerializer.Deserialize<MyObject>(jsonStr);

For more information about excluding properties and nulls check out This Microsoft side

To convert a valid JSON string back, you can use the json_decode() method.

To convert it back to an object use this method:

$jObj = json_decode($jsonString);

And to convert it to a associative array, set the second parameter to true:

$jArr = json_decode($jsonString, true);

By the way to convert your mentioned string back to either of those, you should have a valid JSON string. To achieve it, you should do the following:

1. In the Coords array, remove the two " (double quote marks) from the start and end of the object.
2. The objects in an array are comma seprated (,), so add commas between the objects in the Coords array..

And you will have a valid JSON String..

Here is your JSON String I converted to a valid one: http://pastebin.com/R16NVerw

when you add a new data set to a geom you need to use the data= argument. Or put the arguments in the proper order mapping=..., data=.... Take a look at the arguments for ?geom_line.

Thus:

p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red") 

Or:

p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red") 

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

If your string is in ISO 8601 format, you can also use from_iso8601_timestamp

    for(var i = 0; i < hashes.length; i++)

I was having a similar issue. Things worked in IE6, Firefox, and IE8 running in IE7 compatibility mode; but not in 'normal' IE8. My solution was to put this code in the header

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> 

As to why jquery isn't working in IE8 I'm unclear.

(list.Count() + 9) / 10

Everything else here is either overkill or simply wrong (except for bestsss' answer, which is awesome). We do not want the overhead of a function call (Math.Truncate(), Math.Ceiling(), etc.) when simple math is enough.

OP's question generalizes (pigeonhole principle) to:

How many boxes do I need to store x objects if only y objects fit into each box?

The solution:

1. derives from the realization that the last box might be partially empty, and
2. is (x + y - 1) ÷ y using integer division.

You'll recall from 3^rd grade math that integer division is what we're doing when we say 5 ÷ 2 = 2.

Floating-point division is when we say 5 ÷ 2 = 2.5, but we don't want that here.

Many programming languages support integer division. In languages derived from C, you get it automatically when you divide int types (short, int, long, etc.). The remainder/fractional part of any division operation is simply dropped, thus:

5 / 2 == 2

Replacing our original question with x = 5 and y = 2 we have:

How many boxes do I need to store 5 objects if only 2 objects fit into each box?

The answer should now be obvious: 3 boxes -- the first two boxes hold two objects each and the last box holds one.

(x + y - 1) ÷ y =
(5 + 2 - 1) ÷ 2 =
6 ÷ 2 =
3

So for the original question, x = list.Count(), y = 10, which gives the solution using no additional function calls:

(list.Count() + 9) / 10

You can parameterise it and pass gradle clean build -Pprokey=goodbye

task choiceMyMainClass(type: JavaExec) {
     group = "Execution"
    description = "Run Option main class with JavaExecTask"
    classpath = sourceSets.main.runtimeClasspath

    if (project.hasProperty('prokey')){
        if (prokey == 'hello'){
            main = 'com.sam.home.HelloWorld'
        } 
        else if (prokey == 'goodbye'){
            main = 'com.sam.home.GoodBye'
        }
    } else {
            println 'Invalid value is enterrd';

       // println 'Invalid value is enterrd'+ project.prokey;
    }

proceed = "y", "Y"
if answer in proceed:

Also, you don't want

answer = str(input("Is the information correct? Enter Y for yes or N for no"))

You want

answer = raw_input("Is the information correct? Enter Y for yes or N for no")

input() evaluates whatever is entered as a Python expression, raw_input() returns a string.

Edit: That is only true on Python 2. On Python 3, input is fine, although str() wrapping is still redundant.

If you want to use [System.IO.File]::WriteAllLines(), you should cast second parameter to String[] (if the type of $MyFile is Object[]), and also specify absolute path with $ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath($MyPath), like:

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
Get-ChildItem | ConvertTo-Csv | Set-Variable MyFile
[System.IO.File]::WriteAllLines($ExecutionContext.SessionState.Path.GetUnresolvedProviderPathFromPSPath($MyPath), [String[]]$MyFile, $Utf8NoBomEncoding)

If you want to use [System.IO.File]::WriteAllText(), sometimes you should pipe the second parameter into | Out-String | to add CRLFs to the end of each line explictly (Especially when you use them with ConvertTo-Csv):

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
Get-ChildItem | ConvertTo-Csv | Out-String | Set-Variable tmp
[System.IO.File]::WriteAllText("/absolute/path/to/foobar.csv", $tmp, $Utf8NoBomEncoding)

Or you can use [Text.Encoding]::UTF8.GetBytes() with Set-Content -Encoding Byte:

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding $False
Get-ChildItem | ConvertTo-Csv | Out-String | % { [Text.Encoding]::UTF8.GetBytes($_) } | Set-Content -Encoding Byte -Path "/absolute/path/to/foobar.csv"

see: How to write result of ConvertTo-Csv to a file in UTF-8 without BOM

Tutorial is not really required for this. Read up on encapsulation

private String myField; //"private" means access to this is restricted

public String getMyField()
{
     //include validation, logic, logging or whatever you like here
    return this.myField;
}
public void setMyField(String value)
{
     //include more logic
     this.myField = value;
}

For Online Judges problems that does not allow StringBuilder or StringBuffer, you can do it in place using char[] as following:

public static String reverse(String input){
    char[] in = input.toCharArray();
    int begin=0;
    int end=in.length-1;
    char temp;
    while(end>begin){
        temp = in[begin];
        in[begin]=in[end];
        in[end] = temp;
        end--;
        begin++;
    }
    return new String(in);
}

SELECT * FROM tablename WHERE STR_TO_DATE(columnname, '%d/%m/%Y')
  BETWEEN STR_TO_DATE('29/05/2017', '%d/%m/%Y')
    AND STR_TO_DATE('30/05/2017', '%d/%m/%Y')

It works perfectly :)

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

Live Sample

It's a hexadecimal number.

0x6400 translates to 4*16^2 + 6*16^3 = 25600

Most likely the reason your push did not work is order of execution.

use is a compile time directive. You push is done at execution time:

push ( @INC,"directory_path/more_path");
use Foo.pm;  # In directory path/more_path

You can use a BEGIN block to get around this problem:

BEGIN {
    push ( @INC,"directory_path/more_path");
}
use Foo.pm;  # In directory path/more_path

IMO, it's clearest, and therefore best to use lib:

use lib "directory_path/more_path";
use Foo.pm;  # In directory path/more_path

See perlmod for information about BEGIN and other special blocks and when they execute.

Edit

For loading code relative to your script/library, I strongly endorse File::FindLib

You can say use File::FindLib 'my/test/libs'; to look for a library directory anywhere above your script in the path.

Say your work is structured like this:

   /home/me/projects/
    |- shared/
    |   |- bin/
    |   `- lib/
    `- ossum-thing/
       `- scripts 
           |- bin/
           `- lib/

Inside a script in ossum-thing/scripts/bin:

use File::FindLib 'lib/';
use File::FindLib 'shared/lib/';

Will find your library directories and add them to your @INC.

It's also useful to create a module that contains all the environment set-up needed to run your suite of tools and just load it in all the executables in your project.

use File::FindLib 'lib/MyEnvironment.pm'

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

To examine the problem in detail, you can use Wireshark.

or you can just re-request or re-connect again.

work fine for me ,change ids according to you requirement.

$("#FormId select#status_id_new").val('');
 $("#FormId select#status_id_new").multiselect("refresh");

Here T refers to a Class.It can be a reference type.

You reference a Linux distribution, so you need to install the readline development libraries

On Debian based platforms, like Ubuntu, you can run:

sudo apt-get install libreadline-dev 

and that should install the correct headers in the correct places,.

If you use a platform with yum, like SUSE, then the command should be:

yum install readline-devel

Windows, Linux, some Macs:

ALT+SHIFT+F10, Right, E, Enter, Tab, enter your command line parameters, Enter. ;-)

Mac with "OS X 10.5" key schema:

CTRL+ALT+R, Right, E, Enter, Tab, enter your command line parameters, Enter.

In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.

In case of entity framework FK in dependent must also be its PK so in your case you should use:

public class Boo
{
    [Key, ForeignKey("Foo")]
    public string BooId{get;set;}
    public Foo Foo{get;set;}
}

Or fluent mapping

modelBuilder.Entity<Foo>()
            .HasOptional(f => f.Boo)
            .WithRequired(s => s.Foo);

I have a code that works and use the term calculated, I'm not on postgresSQL pure tho we run on PADB

here is how it's used

create table some_table as
    select  category, 
            txn_type,
            indiv_id, 
            accum_trip_flag,
            max(first_true_origin) as true_origin,
            max(first_true_dest ) as true_destination,
            max(id) as id,
            count(id) as tkts_cnt,
            (case when calculated tkts_cnt=1 then 1 else 0 end) as one_way
    from some_rando_table
    group by 1,2,3,4    ;

First, lets extend the string object. Thanks to Ricardo Peres for the prototype, I think using the variable 'string' works better than 'needle' in the context of making it more readable.

String.prototype.beginsWith = function (string) {
    return(this.indexOf(string) === 0);
};

Then you use it like this. Caution! Makes the code extremely readable.

var pathname = window.location.pathname;
if (pathname.beginsWith('/sub/1')) {
    // Do stuff here
}

I would say no, because the Developer docs on RAM usage state:

...
GC_EXPLICIT

An explicit GC, such as when you call gc() (which you should avoid calling and instead trust the GC to run when needed).

...

I've highlighted the relevant part in bold.

Have a look at the YouTube series, Android Performance Patterns - it will show you tips on managing your app's memory usage (such as using Android's ArrayMaps and SparseArrays instead of HashMaps).

I faced the same problem during 2 days and I found the solution, and it's elegant after googling a lot. I needed xss Ajax for some widget clients which pull datastream from tiers websites to my Rails app. here's how I did.

If:

X is image width,
Y is image height,

then:

img {
    position: absolute;
    top: 50%;
    left: 50%;
    margin-left: -(X/2)px;
    margin-top: -(Y/2)px;
}

But keep in mind this solution is valid only if the only element on your site will be this image. I suppose that's the case here.

Using this method gives you the benefit of fluidity. It won't matter how big (or small) someone's screen is. The image will always stay in the middle.

Based on Jim Lim's answer, I installed the GitHub Markdown gem. That included a script called gfm that takes a filename on the command line and writes the equivalent HTML to standard output. I modified that slightly to save the file to disk and then to open the standard browser with launchy:

#!/usr/bin/env ruby

HELP = <<-help
  Usage: gfm [--readme | --plaintext] [<file>]
  Convert a GitHub-Flavored Markdown file to HTML and write to standard output.
  With no <file> or when <file> is '-', read Markdown source text from standard input.
  With `--readme`, the files are parsed like README.md files in GitHub.com. By default,
  the files are parsed with all the GFM extensions.
help

if ARGV.include?('--help')
  puts HELP
  exit 0
end

root = File.expand_path('../../', __FILE__)
$:.unshift File.expand_path('lib', root)

require 'github/markdown'
require 'tempfile'
require 'launchy'

mode = :gfm
mode = :markdown if ARGV.delete('--readme')
mode = :plaintext if ARGV.delete('--plaintext')

outputFilePath = File.join(Dir.tmpdir, File.basename(ARGF.path))  + ".html"

File.open(outputFilePath, "w") do |outputFile |
    outputFile.write(GitHub::Markdown.to_html(ARGF.read, mode))
end

outputFileUri = 'file:///' + outputFilePath

Launchy.open(outputFileUri)

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

I use the code below to smooth-scroll an item (thisView) to the top.
It works also for GridLayoutManager with views of different heights:

View firstView = mRecyclerView.getChildAt(0);
int toY = firstView.getTop();
int firstPosition = mRecyclerView.getChildAdapterPosition(firstView);
View thisView = mRecyclerView.getChildAt(thisPosition - firstPosition);
int fromY = thisView.getTop();

mRecyclerView.smoothScrollBy(0, fromY - toY);

Seems to work good enough for a quick solution.

Attribute is a public variable inside the class/object. length attribute is a variable of int type.

This problem will happen if you are installing un-signed version of APK. Check if you are install correct APK.

Only such dialog is FileDialog. Its part of WinForms, but its actually only wrapper around WinAPI standard OS file dialog. And I don't think it is ugly, its actually part of OS, so it looks like OS it is run on.

Other way, there is nothing to help you with. You either need to look for 3rd party implementation, either free (and I don't think there are any good) or paid.

JS Code:

function TodayDate(){
        let data= new Date();
        return data.getFullYear().toString()+'-' + (data.getMonth()+1).toString()+'-' + data.getDate().toString()
    }
    document.getElementById('today').innerHTML = '<input type="date" name="Data" value="'+TodayDate()+'" ><br>';

Html Code:

<div id="today" > </div>

A little bit rough but it works!
