Here is an approach, based on MSquare's nice idea for detecting a long press of a button, that has an additional feature: not only is an operation performed in response to a long press, but the operation is repeated until a MotionEvent.ACTION_UP message is received. In this case, the long-press and short-press actions are the same, but they could be different.

Note that, as others have reported, removing the callback in response to a MotionEvent.ACTION_MOVE message prevented the callback from ever getting executed since I could not keep my finger still enough. I got around that problem by ignoring that message.

private void setIncrementButton() {
    final Button btn = (Button) findViewById(R.id.btn);
    final Runnable repeater = new Runnable() {
        @Override
        public void run() {
            increment();
            final int milliseconds = 100;
            btn.postDelayed(this, milliseconds);
        }
    };
    btn.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent e) {
            if (e.getAction() == MotionEvent.ACTION_DOWN) {
                increment();
                v.postDelayed(repeater, ViewConfiguration.getLongPressTimeout());
            } else if (e.getAction() == MotionEvent.ACTION_UP) {
                v.removeCallbacks(repeater);
            }
            return true;
        }
    });
}

private void increment() {
    Log.v("Long Press Example", "TODO: implement increment operation");   
}

You can do:

setContentPane(new JLabel(new ImageIcon("resources/taverna.jpg")));

At first line of the Jframe class constructor, that works fine for me

If you are using a composite key in your bean, your parameter will be an object. You need to adjust your findBy method according to the new combination.

@Embeddable
public class CombinationId implements Serializable {

  private String xId;
  private String yId;
}

public class RealObject implements Serializable, Persistable<CombinationId> {

  @EmbeddedId private CombinationId id;
}

In that case, your repository findBy method should be as this

@Repository
public interface PaymentProfileRepository extends JpaRepository<RealObject, String> {

  List<RealObject> findById_XId(String someString);
}

Use sessionStorage!

$(function(){_x000D_
    $('form').submit{_x000D_
       document.sessionStorage["form-data"] =  $('this').serialize();_x000D_
       document.location.href = 'another-page.html';_x000D_
    }_x000D_
});

At another-page.html:

var formData = document.sessionStorage["form-data"];

You only need to add the following line

yourWebViewName.setWebViewClient(new WebViewClient());

Check this for official documentation.

Ok so I'll combine ghostdog74's answer and the comments, just for fun.

>>> import os
>>> os.stat('c:/pagefile.sys').st_size==0
False

False means a non-empty file.

So let's write a function:

import os

def file_is_empty(path):
    return os.stat(path).st_size==0

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

I implemented a hasOne relation in my parent class, defined both the foreign and local key, it returned an object but the columns of the child must be accessed as an array.
i.e. $parent->child['column']
Kind of confusing.

When rewriting the html is allowed, you can nest <ul>s within the <ul> and just let the inner <li>s display as inline-block. This would also semantically make sense IMHO, as the grouping also is reflected within the html.

<ul>
    <li>
        <ul>
            <li>Item 1</li>
            <li>Item 2</li>
            <li>Item 3</li>
        </ul>
    </li>
    <li>
        <ul>
            <li>Item 4</li>
            <li>Item 5</li>
            <li>Item 6</li>
        </ul>
    </li>
</ul>

li li { display:inline-block; }

For those like me who are brand new to this, here is code with const and an actual way to compare the byte[]'s. I got all of this code from stackoverflow but defined consts so values could be changed and also

// 24 = 192 bits
    private const int SaltByteSize = 24;
    private const int HashByteSize = 24;
    private const int HasingIterationsCount = 10101;


    public static string HashPassword(string password)
    {
        // http://stackoverflow.com/questions/19957176/asp-net-identity-password-hashing

        byte[] salt;
        byte[] buffer2;
        if (password == null)
        {
            throw new ArgumentNullException("password");
        }
        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, SaltByteSize, HasingIterationsCount))
        {
            salt = bytes.Salt;
            buffer2 = bytes.GetBytes(HashByteSize);
        }
        byte[] dst = new byte[(SaltByteSize + HashByteSize) + 1];
        Buffer.BlockCopy(salt, 0, dst, 1, SaltByteSize);
        Buffer.BlockCopy(buffer2, 0, dst, SaltByteSize + 1, HashByteSize);
        return Convert.ToBase64String(dst);
    }

    public static bool VerifyHashedPassword(string hashedPassword, string password)
    {
        byte[] _passwordHashBytes;

        int _arrayLen = (SaltByteSize + HashByteSize) + 1;

        if (hashedPassword == null)
        {
            return false;
        }

        if (password == null)
        {
            throw new ArgumentNullException("password");
        }

        byte[] src = Convert.FromBase64String(hashedPassword);

        if ((src.Length != _arrayLen) || (src[0] != 0))
        {
            return false;
        }

        byte[] _currentSaltBytes = new byte[SaltByteSize];
        Buffer.BlockCopy(src, 1, _currentSaltBytes, 0, SaltByteSize);

        byte[] _currentHashBytes = new byte[HashByteSize];
        Buffer.BlockCopy(src, SaltByteSize + 1, _currentHashBytes, 0, HashByteSize);

        using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, _currentSaltBytes, HasingIterationsCount))
        {
            _passwordHashBytes = bytes.GetBytes(SaltByteSize);
        }

        return AreHashesEqual(_currentHashBytes, _passwordHashBytes);

    }

    private static bool AreHashesEqual(byte[] firstHash, byte[] secondHash)
    {
        int _minHashLength = firstHash.Length <= secondHash.Length ? firstHash.Length : secondHash.Length;
        var xor = firstHash.Length ^ secondHash.Length;
        for (int i = 0; i < _minHashLength; i++)
            xor |= firstHash[i] ^ secondHash[i];
        return 0 == xor;
    }

In in your custom ApplicationUserManager, you set the PasswordHasher property the name of the class which contains the above code.

I know there is a more elegant way to do this and I'm open to suggestions... this is what I did:

          try
            {


             // Set directory for list to be made of
                DirectoryInfo jpegInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo jpgInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo gifInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo tiffInfo = new DirectoryInfo(destinationFolder);
                DirectoryInfo bmpInfo = new DirectoryInfo(destinationFolder);

                // Set file type
                FileInfo[] Jpegs = jpegInfo.GetFiles("*.jpeg");
                FileInfo[] Jpgs = jpegInfo.GetFiles("*.jpg");
                FileInfo[] Gifs = gifInfo.GetFiles("*.gif");
                FileInfo[] Tiffs = gifInfo.GetFiles("*.tiff");
                FileInfo[] Bmps = gifInfo.GetFiles("*.bmp");

        //  listBox1.Items.Add(@"");  // Hack for the first list item no preview problem
        // Iterate through each file, displaying only the name inside the listbox...
        foreach (FileInfo file in Jpegs)
        {
                listBox1.Items.Add(file.Name);
                Photo curPhoto = new Photo();
                curPhoto.PhotoLocation = file.FullName;
                metaData.AddPhoto(curPhoto);
            }

          foreach (FileInfo file in Jpgs)
          {
              listBox1.Items.Add(file.Name);
                Photo curPhoto = new Photo();
                curPhoto.PhotoLocation = file.FullName;
                metaData.AddPhoto(curPhoto);
            }
          foreach (FileInfo file in Gifs)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }
          foreach (FileInfo file in Tiffs)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }
          foreach (FileInfo file in Bmps)
          {
              listBox1.Items.Add(file.Name);
              Photo curPhoto = new Photo();
              curPhoto.PhotoLocation = file.FullName;
              metaData.AddPhoto(curPhoto);
          }

Do not access the composer by composer composer.pher install

use composer install

This is what I do:

Uri selectedImageURI = data.getData();    imageFile = new File(getRealPathFromURI(selectedImageURI)); 

private String getRealPathFromURI(Uri contentURI) {
  Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
  if (cursor == null) { // Source is Dropbox or other similar local file path
      return contentURI.getPath();
      } else { 
      cursor.moveToFirst(); 
      int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
      return cursor.getString(idx); 
  }
}

NOTE: managedQuery() method is deprecated, so I am not using it.

This answer is from m3n0R on question android get real path by Uri.getPath() and I claim no credit. I just thought that people who haven't solved this issue yet could use this.

Is your type really arbitrary? If you know it is just going to be a int float or string you could just do

 if val.dtype == float and np.isnan(val):

assuming it is wrapped in numpy , it will always have a dtype and only float and complex can be NaN

Just create a class or structure that has two members, one List(Of OneItem) and the other Integer and send in an instance of that class.

Edit: Sorry, missed that you had problems with one parameter as well. Just look at Thread Constructor (ParameterizedThreadStart) and that page includes a simple sample.

At the time of writing this I have discovered that chromedriver 2.46 or 2.36 works well with Chrome 75.0.3770.100

Documentation here: http://chromedriver.chromium.org/downloads states align driver and browser alike but I found I had issues even with the most up-to-date driver when using Chrome 75

I am running Selenium 2 on Windows 10 Machine.

Your code is correct. I tested:

r = requests.get("http://www.google.com")
print(r.content)

And it returned plenty of content. Check the url, try "http://www.google.com". Cheers!

If you want to set the compatibility mode in the browser itself and not in the html do the following

1. Open IE 10
2. Press the ALT Key to bring up the IE Menubar
3. Click on the Tools menu
4. Click on compatibility view setting.
5. Clicks check the box; display all the websites in compatibility view or
6. Add only the desired websites to the compatibility view

As shown in the image below. The website should then open up with IE 10 Compatibility view.

Is there a performance issue?

• Please remember to "make it work first before you make it work fast".
  Very few percent of any program are usually relevant for its speed. You can always kick out or simplify an assert if it ever proves to be a performance problem -- and most of them never will.

• Be pragmatic:
  Assume you have a method that processes a non-empty list of tuples and the program logic will break if those tuples are not immutable. You should write:

  def mymethod(listOfTuples):
      assert(all(type(tp)==tuple for tp in listOfTuples))
  

  This is probably fine if your lists tend to be ten entries long, but it can become a problem if they have a million entries. But rather than discarding this valuable check entirely you could simply downgrade it to

  def mymethod(listOfTuples):
      assert(type(listOfTuples[0])==tuple)  # in fact _all_ must be tuples!
  

  which is cheap but will likely catch most of the actual program errors anyway.

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

This one worked for me:

Searching for all *php file in the current directory , and replace the first character of each filename to capital letter:

e.g: test.php => Test.php

for f in *php ; do mv "$f" "$(\sed 's/.*/\u&/' <<< "$f")" ; done

If you want to create a "desired" Guid you can do

var tempGuid = Guid.Parse("<guidValue>");

where <guidValue> would be something like 1A3B944E-3632-467B-A53A-206305310BAE.

Felix Kling did a great comparison on those two, for anyone wondering how to do an export default alongside named exports with module.exports in nodejs

module.exports = new DAO()
module.exports.initDAO = initDAO // append other functions as named export

// now you have
let DAO = require('_/helpers/DAO');
// DAO by default is exported class or function
DAO.initDAO()

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

If you're writing code that you envisage is going to be compiled on a wide variety of platforms, with a number of different compilers, then using these flags yourself will help to ensure you don't produce code that only compiles under GCC.

From php 4.0.6 , there is a function for the exact same thing

function mb_strimwidth can be used for your requirement

<?php
echo mb_strimwidth("Hello World", 0, 10, "...");
//Hello W...
?>

It does have more options though,here is the documentation for this mb_strimwidth

In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*'). See here:

SQL Function

Description

---

REGEXP_LIKE

This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.

...

REGEXP_REPLACE

This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.

...

REGEXP_INSTR

This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.

...

REGEXP_SUBSTR

This function returns the actual substring matching the regular expression pattern you specify.

(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$' for a beginning (^) and end ($) match, e.g.: '^regex.*$'.)

(This is for windows OS but concept can be applied to other OS)

Running command node -v will be able to confirm if it is installed, however it will not be able to confirm if it is NOT installed. (Executable may not be on your PATH)

Two ways you can check if it is actually installed:

1. Check default install location C:\Program Files\nodejs\

or

2. Go to System Settings -> Add or Remove Programs and filter by node, it should show you if you have it installed. For me, it shows as title:"Node.js" and description "Node.js Foundation", with no version specified. Install size is 52.6MB

If you don't have it installed, get it from here https://nodejs.org/en/download/

you said that:

`mony = float(1234.5)
print(money)      #output is 1234.5
'${:,.2f}'.format(money)
print(money)

did not work.... Have you coded exactly that way? This should work (see the little difference):

money = float(1234.5)      #next you used format without printing, nor affecting value of "money"
amountAsFormattedString = '${:,.2f}'.format(money)
print( amountAsFormattedString )

Although this question has already been answered, I think this approach is better : http://jsfiddle.net/kjy112/3CvaD/ extract from this question on StackOverFlow google maps - open marker infowindow given the coordinates:

Each marker gets an "infowindow" entry :

function createMarker(lat, lon, html) {
    var newmarker = new google.maps.Marker({
        position: new google.maps.LatLng(lat, lon),
        map: map,
        title: html
    });

    newmarker['infowindow'] = new google.maps.InfoWindow({
            content: html
        });

    google.maps.event.addListener(newmarker, 'mouseover', function() {
        this['infowindow'].open(map, this);
    });
}

Try this:

mtcars %>%
  group_by(am, gear) %>%
  summarise(n = n()) %>%
  mutate(freq = n / sum(n))

#   am gear  n      freq
# 1  0    3 15 0.7894737
# 2  0    4  4 0.2105263
# 3  1    4  8 0.6153846
# 4  1    5  5 0.3846154

From the dplyr vignette:

When you group by multiple variables, each summary peels off one level of the grouping. That makes it easy to progressively roll-up a dataset.

Thus, after the summarise, the last grouping variable specified in group_by, 'gear', is peeled off. In the mutate step, the data is grouped by the remaining grouping variable(s), here 'am'. You may check grouping in each step with groups.

The outcome of the peeling is of course dependent of the order of the grouping variables in the group_by call. You may wish to do a subsequent group_by(am), to make your code more explicit.

For rounding and prettification, please refer to the nice answer by @Tyler Rinker.

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

GregorianCalendar c = new GregorianCalendar();
c.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

You could subscribe to the TextChanged event on the TextBox and if the text is empty set the Button to disabled. Or you could bind the Button.IsEnabled property to the TextBox.Text property and use a converter that returns true if there is any text and false otherwise.

Solution for Swift 2:

let singleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSingleTap))
singleTapGesture.numberOfTapsRequired = 1 // Optional for single tap
view.addGestureRecognizer(singleTapGesture)

let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
doubleTapGesture.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTapGesture)

singleTapGesture.requireGestureRecognizerToFail(doubleTapGesture)

Alternatively to calling plt.show() at the end of the script, you can also control each figure separately doing:

f = plt.figure(1)
plt.hist........
............
f.show()

g = plt.figure(2)
plt.hist(........
................
g.show()

raw_input()

In this case you must call raw_input to keep the figures alive. This way you can select dynamically which figures you want to show

Note: raw_input() was renamed to input() in Python 3

You can use Tabindex to solve this issue. Also changing the order of the buttons would be a more efficient way to achieve this.

Change the order of the buttons and add float values to assign them the desired position you want to show in your HTML view.

    {
        System.out.println(s.substring(0,i));
        System.out.println(s.substring(i+1));
    }
}

As mentioned by everyone, split() is the best option which may be used in your case. An alternative method can be using substring().

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

<a href="javascript:window.open('document.aspx','mypopuptitle','width=600,height=400')">open popup</a>

There are at least 5 ways to do this:

If you want to convert to integers only, another fast (and short) way is the double-bitwise not (i.e. using two tilde characters):

e.g.

~~x;

Reference: http://james.padolsey.com/cool-stuff/double-bitwise-not/

The 5 common ways I know so far to convert a string to a number all have their differences (there are more bitwise operators that work, but they all give the same result as ~~). This JSFiddle shows the different results you can expect in the debug console: http://jsfiddle.net/TrueBlueAussie/j7x0q0e3/22/

var values = ["123",
          undefined,
          "not a number",
          "123.45",
          "1234 error",
          "2147483648",
          "4999999999"
          ];

for (var i = 0; i < values.length; i++){
    var x = values[i];

    console.log(x);
    console.log(" Number(x) = " + Number(x));
    console.log(" parseInt(x, 10) = " + parseInt(x, 10));
    console.log(" parseFloat(x) = " + parseFloat(x));
    console.log(" +x = " + +x);
    console.log(" ~~x = " + ~~x);
}

Debug console:

123
  Number(x) = 123
  parseInt(x, 10) = 123
  parseFloat(x) = 123
  +x = 123
  ~~x = 123
undefined
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
null
  Number(x) = 0
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = 0
  ~~x = 0
"not a number"
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
123.45
  Number(x) = 123.45
  parseInt(x, 10) = 123
  parseFloat(x) = 123.45
  +x = 123.45
  ~~x = 123
1234 error
  Number(x) = NaN
  parseInt(x, 10) = 1234
  parseFloat(x) = 1234
  +x = NaN
  ~~x = 0
2147483648
  Number(x) = 2147483648
  parseInt(x, 10) = 2147483648
  parseFloat(x) = 2147483648
  +x = 2147483648
  ~~x = -2147483648
4999999999
  Number(x) = 4999999999
  parseInt(x, 10) = 4999999999
  parseFloat(x) = 4999999999
  +x = 4999999999
  ~~x = 705032703

The ~~x version results in a number in "more" cases, where others often result in undefined, but it fails for invalid input (e.g. it will return 0 if the string contains non-number characters after a valid number).

Overflow

Please note: Integer overflow and/or bit truncation can occur with ~~, but not the other conversions. While it is unusual to be entering such large values, you need to be aware of this. Example updated to include much larger values.

Some Perf tests indicate that the standard parseInt and parseFloat functions are actually the fastest options, presumably highly optimised by browsers, but it all depends on your requirement as all options are fast enough: http://jsperf.com/best-of-string-to-number-conversion/37

This all depends on how the perf tests are configured as some show parseInt/parseFloat to be much slower.

My theory is:

• Lies
• Darn lines
• Statistics
• JSPerf results :)

The better way to do this is creating a fake array in component:

In Component:

fakeArray = new Array(12);

InTemplate:

<ng-container *ngFor = "let n of fakeArray">

I had this problem. I searched the internet, took all advices, changes configurations, but the problem is still there. Finally with the help of the server administrator, he found that the problem lies in MySQL database column definition. one of the columns in the a table was assigned to 'Longtext' which leads to allocate 4,294,967,295 bites of memory. It seems working OK if you don't use MySqli prepare statement, but once you use prepare statement, it tries to allocate that amount of memory. I changed the column type to Mediumtext which needs 16,777,215 bites of memory space. The problem is gone. Hope this help.

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

Booleans default value is false only for classes' fields. If within a method, you have to initialize your variable by true or false. Thus for example in your case, you'll have a compilation error.

Moreover, I don't really get the point, but the only way to enter within a if is to evaluate the condition to true.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

Currently experienced this problem with my Nexus 5, when attempting to sideload latest 4.4.1 OTA update via stock recovery.

Solution:

1. Open Android SDK Manager (in console get to sdk directory then run tools\android)
2. Download/install latest USB drivers (under Extras).
3. In Windows Device Manager (devmgmt.msc), right click the Nexus 5 device and select Update Driver Software.
4. Browse My Computer for driver software > Android SDK Dir > Extras > usb_driver

Two issues:

1. You're passing the jQuery wrapper of the element into parseInt, which isn't what you want, as parseInt will call toString on it and get back "[object Object]". You need to use val or text or something (depending on what the element is) to get the string you want.

2. You're not telling parseInt what radix (number base) it should use, which puts you at risk of odd input giving you odd results when parseInt guesses which radix to use.

Fix if the element is a form field:

//                               vvvvv-- use val to get the value
var test = parseInt($("#testid").val(), 10);
//                                    ^^^^-- tell parseInt to use decimal (base 10)

Fix if the element is something else and you want to use the text within it:

//                               vvvvvv-- use text to get the text
var test = parseInt($("#testid").text(), 10);
//                                     ^^^^-- tell parseInt to use decimal (base 10)

Did you try ../../env_${env}.properties ?

Normally we do the following when module2 is on the same level as the sub-modules

<modules>
    <module>../sub-module1</module>
    <module>../sub-module2</module>
    <module>../sub-module3</module>
</modules>

I would think the ../.. would let you jump up two levels. If not, you might want to contact the plug in authors and see if this is a known issue.

I had same problem. It was resolved by following css line;

h1{margin-top:0px}

My main div contained h1 tag in the beginning.

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

Unless there is a strong advantage to running your user form in Excel then I would go with a 100% Access solution that would export the reports and data to Excel on an ad-hoc basis.

From what you describe, Access seems the stronger contender as it is built for working with data:
you would have a lot more tools at your disposal to solve any data problems than have to go around the limitations of Excel and shoehorn it into becoming Access...

As for your questions:

1. Very easy. There have been some other questions on SO on that subject.
   See for instance this one and that one.

2. Don't know, but I would guess that there could be a small penalty.
   The biggest difficulty I see is trying to get all the functionalities that Access gives you and re-creating some of these in Excel.

3. Yes, you can have multiple Excel users and a single Access database.
   Here again, using Access as a front-end and keeping the data in a linked Access database on your network would make more sense and it's easy as pie, there's even a wizard in Access to help you do that: it's just 1 click away.

Really, as most other people have said, take a tiny bit of time to get acquainted with Access, it will save you a lot of time and trouble.
You may know Excel better but if you've gone 80% of the way already if you know VBA and are familiar with the Office object model.

Other advantages of doing it in Access: the Access 2007 runtime is free, meaning that if you were to deploy to app to 1 or 30 PC it would cost you the same: nothing.
You only need one full version of Access for your development work (the Runtime doesn't have the designers).

Browsers obtain the date-input format from user's system date format.

(Tested in supported browsers, Chrome, Edge.)

As there is no standard defined by specs as of now to change the style of date control, its not possible to implement the same in browsers.

Users can type a date value into the text field of an input[type=date] with the date format shown in the box as gray text. This format is obtained from the operating system's setting. Web authors have no way to change the date format because there currently is no standards to specify the format.

So no need to change it, if we don't change anything, users will see the date-input's format same as they have configured in the system/device settings and which they are comfortable with or matches with their locale.

Remember, this is just the UI format on the screen which users see, in your JavaScript/backend you can always keep your desired format to work with.

Refer google developers page on same.

The zoo package has the function of as.yearmon can help to convert.

require(zoo)

df$ym<-as.yearmon(df$date, "%Y %m")

Update for 2018. You can use:

global $product;
echo wc_display_product_attributes( $product );

To customise the output, copy plugins/woocommerce/templates/single-product/product-attributes.php to themes/theme-child/woocommerce/single-product/product-attributes.php and modify that.

The STAThreadAttribute is essentially a requirement for the Windows message pump to communicate with COM components. Although core Windows Forms does not use COM, many components of the OS such as system dialogs do use this technology.

MSDN explains the reason in slightly more detail:

STAThreadAttribute indicates that the COM threading model for the application is single-threaded apartment. This attribute must be present on the entry point of any application that uses Windows Forms; if it is omitted, the Windows components might not work correctly. If the attribute is not present, the application uses the multithreaded apartment model, which is not supported for Windows Forms.

This blog post (Why is STAThread required?) also explains the requirement quite well. If you want a more in-depth view as to how the threading model works at the CLR level, see this MSDN Magazine article from June 2004 (Archived, Apr. 2009).

This table shows the difference. protected internal is the same as protected, except it also allows access from other classes in the same assembly.

You can use sp_columns, a stored procedure for describing the table.

exec sp_columns TableName

You can also use sp_help.

I got this error, hope this will help someone:

const firstName = 'Joe';
const lastName = 'Blogs';
const wholeName = firstName + ' ' lastName + '.';

The problem was that I was missing a plus (+) between the empty space and lastName. This is a super simplified example: I was concatenating about 9 different parts so it was hard to spot the error.

Summa summarum: if you get "SyntaxError: missing ; before statement", don't look at what is wrong with the the semicolon (;) symbols in your code, look for an error in syntax on that line.

In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.

When running the Team Explorer version, only the Blank Solution option was available.

The Team Explorer EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"

Once I launched the correct EXE, Visual Studio started working as expected.

The Professional EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"

It is not possible with the default Link List web part, but there are resources describing how to extend Sharepoint server-side to add this functionality.

random.sample(population, k)

It is used for randomly sampling a sample of length 'k' from a population. returns a 'k' length list of unique elements chosen from the population sequence or set

it returns a new list and leaves the original population unchanged and the resulting list is in selection order so that all sub-slices will also be valid random samples

I am putting up an example in which I am splitting a dataset randomly. It is basically a function in which you pass x_train(population) as an argument and return indices of 60% of the data as D_test.

import random

def randomly_select_70_percent_of_data_from_1_to_length(x_train):
    return random.sample(range(0, len(x_train)), int(0.6*len(x_train)))

Every Ansible task when run can save its results into a variable. To do this, you have to specify which variable to save the results into. Do this with the register parameter, independently of the module used.

Once you save the results to a variable you can use it later in any of the subsequent tasks. So for example if you want to get the standard output of a specific task you can write the following:

---
- hosts: localhost
  tasks:
    - shell: ls
      register: shell_result

    - debug:
        var: shell_result.stdout_lines

Here register tells ansible to save the response of the module into the shell_result variable, and then we use the debug module to print the variable out.

An example run would look like the this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
changed: [localhost]

TASK [debug] *******************************************************************
ok: [localhost] => {
    "shell_result.stdout_lines": [
        "play.yml"
    ]
}

Responses can contain multiple fields. stdout_lines is one of the default fields you can expect from a module's response.

Not all fields are available from all modules, for example for a module which doesn't return anything to the standard out you wouldn't expect anything in the stdout or stdout_lines values, however the msg field might be filled in this case. Also there are some modules where you might find something in a non-standard variable, for these you can try to consult the module's documentation for these non-standard return values.

Alternatively you can increase the verbosity level of ansible-playbook. You can choose between different verbosity levels: -v, -vvv and -vvvv. For example when running the playbook with verbosity (-vvv) you get this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
(...)
changed: [localhost] => {
    "changed": true,
    "cmd": "ls",
    "delta": "0:00:00.007621",
    "end": "2017-02-17 23:04:41.912570",
    "invocation": {
        "module_args": {
            "_raw_params": "ls",
            "_uses_shell": true,
            "chdir": null,
            "creates": null,
            "executable": null,
            "removes": null,
            "warn": true
        },
        "module_name": "command"
    },
    "rc": 0,
    "start": "2017-02-17 23:04:41.904949",
    "stderr": "",
    "stdout": "play.retry\nplay.yml",
    "stdout_lines": [
        "play.retry",
        "play.yml"
    ],
    "warnings": []
}

As you can see this will print out the response of each of the modules, and all of the fields available. You can see that the stdout_lines is available, and its contents are what we expect.

To answer your main question about the jenkins_script module, if you check its documentation, you can see that it returns the output in the output field, so you might want to try the following:

tasks:
  - jenkins_script:
      script: (...)
    register: jenkins_result

  - debug:
      var: jenkins_result.output

8 years later I stumbled upon this gem, and yet I don't believe OP's original question was really answered:

so I came up with the following code to trim the newline character

While the bufio.Reader type supports a ReadLine() method which both removes \r\n and \n it is meant as a low-level function which is awkward to use because repeated checks are necessary.

IMO an idiomatic way to remove whitespace is to use Golang's strings library:

input, _ = src.ReadString('\n')

// more specific to the problem of trailing newlines
actual = strings.TrimRight(input, "\r\n")

// or if you don't mind to trim leading and trailing whitespaces 
actual := strings.TrimSpace(input)

See this example in action in the Golang playground: https://play.golang.org/p/HrOWH0kl3Ww

Imports System.Runtime.InteropServices

I've found mine in

\ProgramData\MySQL\MySQL Server 8.0\

(It is a hidden folder)

You can type win+R and write %PROGRAMDATA% to access that folder, or just enable show hidden folder.

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

I'd just use an if statement. In this case:

Type nodeType = node.GetType();
if (nodeType == typeof(CasusNodeDTO))
{
}
else ... 

The other way to do this is:

if (node is CasusNodeDTO)
{
}
else ...

The first example is true for exact types only, where the latter checks for inheritance too.

print("My type is %s" % type(someObject)) # the type in python

or...

print("My type is %s" % type(someObject).__name__) # the object's type (the class you defined)

As many others pointed out if you are trying to add a new element at the end of list then something like, array[array.length-1]=x; should do. But this will replace the existing element.

For something like continuous addition to the array. You can keep track of the index and go on adding elements till you reach end and have the function that does the addition return you the next index, which in turn will tell you how many more elements can fit in the array.

Of course in both the cases the size of array will be predefined. Vector can be your other option since you do not want arraylist, which will allow you all the same features and functions and additionally will take care of incrementing the size.

Coming to the part where you want StringBuffer to array. I believe what you are looking for is the getChars(int srcBegin, int srcEnd,char[] dst,int dstBegin) method. Look into it that might solve your doubts. Again I would like to point out that after managing to get an array out of it, you can still only replace the last existing element(character in this case).

This is kind of a hack, but does seem to work. Below are the steps and an example of modifying a table type. One note is the sp_refreshsqlmodule will fail if the change you made to the table type is a breaking change to that object, typically a procedure.

1. Use sp_rename to rename the table type, I typically just add z to the beginning of the name.
2. Create a new table type with the original name and any modification you need to make to the table type.
3. Step through each dependency and run sp_refreshsqlmodule on it.
4. Drop the renamed table type.

EXEC sys.sp_rename 'dbo.MyTableType', 'zMyTableType';
GO
CREATE TYPE dbo.MyTableType AS TABLE(
    Id INT NOT NULL,
    Name VARCHAR(255) NOT NULL
);
GO
DECLARE @Name NVARCHAR(776);

DECLARE REF_CURSOR CURSOR FOR
SELECT referencing_schema_name + '.' + referencing_entity_name
FROM sys.dm_sql_referencing_entities('dbo.MyTableType', 'TYPE');

OPEN REF_CURSOR;

FETCH NEXT FROM REF_CURSOR INTO @Name;
WHILE (@@FETCH_STATUS = 0)
BEGIN
    EXEC sys.sp_refreshsqlmodule @name = @Name;
    FETCH NEXT FROM REF_CURSOR INTO @Name;
END;

CLOSE REF_CURSOR;
DEALLOCATE REF_CURSOR;
GO
DROP TYPE dbo.zMyTableType;
GO

To include Unicode characters in your Python source code, you can use Unicode escape characters in the form \u0123 in your string. In Python 2.x, you also need to prefix the string literal with 'u'.

Here's an example running in the Python 2.x interactive console:

>>> print u'\u0420\u043e\u0441\u0441\u0438\u044f'
??????

In Python 2, prefixing a string with 'u' declares them as Unicode-type variables, as described in the Python Unicode documentation.

In Python 3, the 'u' prefix is now optional:

>>> print('\u0420\u043e\u0441\u0441\u0438\u044f')
??????

If running the above commands doesn't display the text correctly for you, perhaps your terminal isn't capable of displaying Unicode characters.

These examples use Unicode escapes (\u...), which allows you to print Unicode characters while keeping your source code as plain ASCII. This can help when working with the same source code on different systems. You can also use Unicode characters directly in your Python source code (e.g. print u'??????' in Python 2), if you are confident all your systems handle Unicode files properly.

For information about reading Unicode data from a file, see this answer:

Character reading from file in Python

string.Format is your friend.

String.Format("{0:0.00}", 123.4567);      // "123.46"

@FindBy(xpath = "//span[@class='y2' and contains(text(), 'Your Text')] ") 
private WebElementFacade emailLinkToVerifyAccount;

This approach will work for you, hopefully.

This will be the second question in a row I've answered with this, so I think it's worth pointing out that I have no affiliation with this product, but I use it and love it and think it's the right answer to this question too: DbVisualizer.

I had originally asked myself the question "Do I need a PDB file deployed to my customer's machine?", and after reading this post, decided to exclude the file.

Everything worked fine, until today, when I was trying to figure out why a message box containing an Exception.StackTrace was missing the file and line number information - necessary for troubleshooting the exception. I re-read this post and found the key nugget of information: that although the PDB is not necessary for the app to run, it is necessary for the file and line numbers to be present in the StackTrace string. I included the PDB file in the executable folder and now all is fine.

I've seen many answers with many votes advocating using the ternary operator. The ternary is great if a) you do have an alternative option and b) you are returning a fairly simple value from a simple condition. But...

The original question didn't have an alternative, and the ternary operator with only a single (real) branch forces you to return a confected answer.

I think the most common variation is lemons ? 'foo...' : '', and, as you'll know from reading the myriad of articles for any language on true, false, truthy, falsey, null, nil, blank, empty (with our without ?) , you are entering a minefield (albeit a well documented minefield.)

As soon as any part of the ternary gets complicated you are better off with a more explicit form of conditional.

A long way to say that I am voting for if (lemons) "foo".

You could join the table against itself:

select
   t.jobId, t.jobName,
   count(p1.jobId) as Priority1,
   count(p2.jobId) as Priority2,
   count(p3.jobId) as Priority3,
   count(p4.jobId) as Priority4,
   count(p5.jobId) as Priority5
from
   theTable t
   left join theTable p1 on p1.jobId = t.jobId and p1.jobName = t.jobName and p1.Priority = 1
   left join theTable p2 on p2.jobId = t.jobId and p2.jobName = t.jobName and p2.Priority = 2
   left join theTable p3 on p3.jobId = t.jobId and p3.jobName = t.jobName and p3.Priority = 3
   left join theTable p4 on p4.jobId = t.jobId and p4.jobName = t.jobName and p4.Priority = 4
   left join theTable p5 on p5.jobId = t.jobId and p5.jobName = t.jobName and p5.Priority = 5
group by
   t.jobId, t.jobName

Or you could use case inside a sum:

select
   jobId, jobName,
   sum(case Priority when 1 then 1 else 0 end) as Priority1,
   sum(case Priority when 2 then 1 else 0 end) as Priority2,
   sum(case Priority when 3 then 1 else 0 end) as Priority3,
   sum(case Priority when 4 then 1 else 0 end) as Priority4,
   sum(case Priority when 5 then 1 else 0 end) as Priority5
from
   theTable
group by
   jobId, jobName

function starts_with($s, $prefix){
    // returns a bool
    return strpos($s, $prefix) === 0;
}

starts_with($variable, "_");

 var myEle = document.getElementById("myElement");
    if(myEle){
        var myEleValue= myEle.value;
    }

the return of getElementById is null if an element is not actually present inside the dom, so your if statement will fail, because null is considered a false value

I suggest Freewall. It is a cross-browser and responsive jQuery plugin to help you create many types of grid layouts: flexible layouts, images layouts, nested grid layouts, metro style layouts, pinterest like layouts ... with nice CSS3 animation effects and call back events. Freewall is all-in-one solution for creating dynamic grid layouts for desktop, mobile, and tablet.

Home page and document: also found here.

It depends what you wanted to do with that column e.g. here's an example of appending a new column to a recordset which can be updated on the client side:

Sub MSDataShape_AddNewCol()

  Dim rs As ADODB.Recordset
  Set rs = CreateObject("ADODB.Recordset")
  With rs
    .ActiveConnection = _
    "Provider=MSDataShape;" & _
    "Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Tempo\New_Jet_DB.mdb"
    .Source = _
    "SHAPE {" & _
    " SELECT ExistingField" & _
    " FROM ExistingTable" & _
    " ORDER BY ExistingField" & _
    "} APPEND NEW adNumeric(5, 4) AS NewField"

    .LockType = adLockBatchOptimistic

    .Open

    Dim i As Long
    For i = 0 To .RecordCount - 1
      .Fields("NewField").Value = Round(.Fields("ExistingField").Value, 4)
      .MoveNext
    Next

    rs.Save "C:\rs.xml", adPersistXML

  End With
End Sub

I think this one is awesome

ls -1 | awk 'ORS=","'

ORS is the "output record separator" so now your lines will be joined with a comma.

I typically free every allocated block once I'm sure that I'm done with it. Today, my program's entry point might be main(int argc, char *argv[]) , but tomorrow it might be foo_entry_point(char **args, struct foo *f) and typed as a function pointer.

So, if that happens, I now have a leak.

Regarding your second question, if my program took input like a=5, I would allocate space for a, or re-allocate the same space on a subsequent a="foo". This would remain allocated until:

1. The user typed 'unset a'
2. My cleanup function was entered, either servicing a signal or the user typed 'quit'

I can not think of any modern OS that does not reclaim memory after a process exits. Then again, free() is cheap, why not clean up? As others have said, tools like valgrind are great for spotting leaks that you really do need to worry about. Even though the blocks you example would be labeled as 'still reachable' , its just extra noise in the output when you're trying to ensure you have no leaks.

Another myth is "If its in main(), I don't have to free it", this is incorrect. Consider the following:

char *t;

for (i=0; i < 255; i++) {
    t = strdup(foo->name);
    let_strtok_eat_away_at(t);
}

If that came prior to forking / daemonizing (and in theory running forever), your program has just leaked an undetermined size of t 255 times.

A good, well written program should always clean up after itself. Free all memory, flush all files, close all descriptors, unlink all temporary files, etc. This cleanup function should be reached upon normal termination, or upon receiving various kinds of fatal signals, unless you want to leave some files laying around so you can detect a crash and resume.

Really, be kind to the poor soul who has to maintain your stuff when you move on to other things .. hand it to them 'valgrind clean' :)

This error is caused by:

Y = Dataset.iloc[:,18].values

Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.

This is quite the tricky thing to do in Android and I haven't done it yet. But maybe these links may help you:

UPDATE: Since this answer was written, Visibility was introduced and provides the best solution to this problem.

You can use Opacity with an opacity: of 0.0 to draw make an element hidden but still occupy space.

To make it not occupy space, replace it with an empty Container().

EDIT: To wrap it in an Opacity object, do the following:

            new Opacity(opacity: 0.0, child: new Padding(
              padding: const EdgeInsets.only(
                left: 16.0,
              ),
              child: new Icon(pencil, color: CupertinoColors.activeBlue),
            ))

I had a similar problem, I tried to clear all the caches possible (tried almost all the solutions above) and the only thing that worked for me was to kill the expo app and to restart it.

With C++11, the above would be possible for basic types as

class Foo {
public:  
  static constexpr int MEMBER = 1;  
};

The constexpr part creates a static expression as opposed to a static variable - and that behaves just like an extremely simple inline method definition. The approach proved a bit wobbly with C-string constexprs inside template classes, though.

I faced the same issue and got the same deprecation warning. I was using a numpy array of [23, 276] when I got the message. I tried reshaping it as per the warning and end up in nowhere. Then I select each row from the numpy array (as I was iterating over it anyway) and assigned it to a list variable. It worked then without any warning.

array = []
array.append(temp[0])

Then you can use the python list object (here 'array') as an input to sk-learn functions. Not the most efficient solution, but worked for me.

Have a look at org.apache.commons.lang.StringUtils#rightPad(String str, int size, char padChar).

But the algorithm is very simple (pad right up to size chars):

public String pad(String str, int size, char padChar)
{
  StringBuilder padded = new StringBuilder(str);
  while (padded.length() < size)
  {
    padded.append(padChar);
  }
  return padded.toString();
}

A list comprehension is likely the cleanest way:

>>> L = [0, 23, 234, 89, None, 0, 35, 9
>>> [x for x in L if x is not None]
[0, 23, 234, 89, 0, 35, 9]

There is also a functional programming approach but it is more involved:

>>> from operator import is_not
>>> from functools import partial
>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> list(filter(partial(is_not, None), L))
[0, 23, 234, 89, 0, 35, 9]

to answer the first part of your question:

run

% mysqladmin -p -u <user-name> variables

and check the 'socket' variable

Something like this might work:

$("body").attr("class", "about");

It uses jQuery's attr() to add the class 'about' to the body.

In your case, you can use root directive, because $uri part of the location directive is the same with last root directive part.

Nginx documentation advices it as well:
When location matches the last part of the directive’s value:

location /images/ {
    alias /data/w3/images/;
}

it is better to use the root directive instead:

location /images/ {
    root /data/w3;
}

and root directive will append $uri to the path.

if request.method == 'POST':
    expectedphraseform = ExpectedphraseForm(request.POST)
    bannedphraseform = BannedphraseForm(request.POST)
    if expectedphraseform.is_valid():
        expectedphraseform.save()
        return HttpResponse("Success")
    if bannedphraseform.is_valid():
        bannedphraseform.save()
        return HttpResponse("Success")
else:
    bannedphraseform = BannedphraseForm()
    expectedphraseform = ExpectedphraseForm()
return render(request, 'some.html',{'bannedphraseform':bannedphraseform, 'expectedphraseform':expectedphraseform})

This worked for me accurately as I wanted. This Approach has a single problem that it validates both the form's errors. But works Totally fine.

1. sudo vim /etc/apache2/httpd.conf
2. Insert the following line at the httpd.conf: ServerName localhost
3. Just restart the Apache: sudo /etc/init.d/apache2 restart

iOS 7 has a new method that allows you to draw a view hierarchy into the current graphics context. This can be used to get an UIImage very fast.

I implemented a category method on UIView to get the view as an UIImage:

- (UIImage *)pb_takeSnapshot {
    UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, [UIScreen mainScreen].scale);

    [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];

    // old style [self.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

It is considerably faster then the existing renderInContext: method.

Reference: https://developer.apple.com/library/content/qa/qa1817/_index.html

UPDATE FOR SWIFT: An extension that does the same:

extension UIView {

    func pb_takeSnapshot() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)

        drawViewHierarchyInRect(self.bounds, afterScreenUpdates: true)

        // old style: layer.renderInContext(UIGraphicsGetCurrentContext())

        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}

UPDATE FOR SWIFT 3

    UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.main.scale)

    drawHierarchy(in: self.bounds, afterScreenUpdates: true)

    let image = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    return image

$pageURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
if ($_SERVER["SERVER_PORT"] != "80")
{
    $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} 
else 
{
    $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;

You can JOIN with the same table more than once by giving the joined tables an alias, as in the following example:

SELECT 
    airline, flt_no, fairport, tairport, depart, arrive, fare
FROM 
    flights
INNER JOIN 
    airports from_port ON (from_port.code = flights.fairport)
INNER JOIN
    airports to_port ON (to_port.code = flights.tairport)
WHERE 
    from_port.code = '?' OR to_port.code = '?' OR airports.city='?'

Note that the to_port and from_port are aliases for the first and second copies of the airports table.

I know it's to late to answer this question. But if you are working with collection of type IList<> and you don't care about an order of the returned collection, then this method is working faster. I've used Mark Byers answer and made a little changes. So now method TakeLast is:

public static IEnumerable<T> TakeLast<T>(IList<T> source, int takeCount)
{
    if (source == null) { throw new ArgumentNullException("source"); }
    if (takeCount < 0) { throw new ArgumentOutOfRangeException("takeCount", "must not be negative"); }
    if (takeCount == 0) { yield break; }

    if (source.Count > takeCount)
    {
        for (int z = source.Count - 1; takeCount > 0; z--)
        {
            takeCount--;
            yield return source[z];
        }
    }
    else
    {
        for(int i = 0; i < source.Count; i++)
        {
            yield return source[i];
        }
    }
}

For test I have used Mark Byers method and kbrimington's andswer. This is test:

IList<int> test = new List<int>();
for(int i = 0; i<1000000; i++)
{
    test.Add(i);
}

Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();

IList<int> result = TakeLast(test, 10).ToList();

stopwatch.Stop();

Stopwatch stopwatch1 = new Stopwatch();
stopwatch1.Start();

IList<int> result1 = TakeLast2(test, 10).ToList();

stopwatch1.Stop();

Stopwatch stopwatch2 = new Stopwatch();
stopwatch2.Start();

IList<int> result2 = test.Skip(Math.Max(0, test.Count - 10)).Take(10).ToList();

stopwatch2.Stop();

And here are results for taking 10 elements:

and for taking 1000001 elements results are:

I think, this is you exactly needed.

Here drawable(xml) file that creates rounded rectangle. round_rect_shape.xml

-> In the above code, LinearLayout having the background(That is the key role to place to create rounded rectangle). So you can place any view like TextView, EditText... in that LinearLayout to see background as round rectangle for all.

This seems to work only for some characters ... including special characters for German, Portuguese, French. However, I ran into trouble with Russian, Hindi and Mandarin characters. These are not converted to Properties format 'native2ascii', instead get saved with ?? ?? ??
The only way I could get my app to display these characters correctly is by putting them in the properties file translated to UTF-8 format - as \u0915 instead of ?, or \u044F instead of ?. Any advice?

Swift 4

button.titleLabel?.font = UIFont(name: "Font_Name_Here", size: Font_Size_Here)

Objective-c

[button.titleLabel setFont:[UIFont fontWithName:@“Font_Name_Here” size: Font_Size_Here]];

Example:

Font_Name = "Helvetica"

Font_Size = 16.0

Hope it helps.

If this is a simple project, you should be able to drag the txt file right into the project folder. Specifically, the "project folder" would be the highest level folder. I tried to do this (for a homework project that I'm doing) by putting the txt file in the src folder, but that didn't work. But finally I figured out to put it in the project file.

A good tutorial for this is http://www.vogella.com/articles/JavaIO/article.html. I used this as an intro to i/o and it helped.

Alternative method: In Eclipse 3.6, under "Line Wrapping" then "General Settings" there is an option to "Never join already wrapped lines." This means the formatter will wrap long lines but not undo any wrapping you already have.

Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.

<ul>
    <li class="even"><a href="link">Link 1</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li class="even"><a href="link">Link 3</a></li>
    <li class="odd"><a href="link">Link 4</a></li>
    <li class="even"><a href="link">Link 5</a></li>
</ul>

In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:

li.even { background-color: red; }
li.odd { background-color: blue; }

You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?

lodash and ES5

var song = _.find(songs, {id:id});

lodash and ES6

let song = _.find(songs, {id});

docs at https://lodash.com/docs#find

You can get the element itself in .each(), try this instead of using this

$('.Count').each(function (index, value) {
    jQuery({ Counter: 0 }).animate({ Counter: value.text() }, {
        duration: 1000,
        easing: 'swing',
        step: function () {
            value.text(Math.ceil(this.Counter));
        }
    });
});

Create a Pivot Table. It has these features and many more.

If you are dead-set on doing this yourself then you could add shapes to the worksheet and use VBA to hide and unhide rows and columns on clicking the shapes.

Python 3 only answer (that doesn't use slicing or throw away the rest of the list, but might be good enough anyway) is use unpacking generalizations to get first and last separate from the middle:

first, *_, last = some_list

The choice of _ as the catchall for the "rest" of the arguments is arbitrary; they'll be stored in the name _ which is often used as a stand-in for "stuff I don't care about".

Unlike many other solutions, this one will ensure there are at least two elements in the sequence; if there is only one (so first and last would be identical), it will raise an exception (ValueError).

The best way that I usually use is very simple, I fully disable context menu in the whole page, pure html+javascript:

 <body oncontextmenu="return false;">

That's it! I do that because you can always see the source by right click.
Ok, you say: "I can use directly the browser view source" and it's true but we start from the fact that you CAN'T stop downloading html5 videos.

From this thread, there are different ways to do this:

double r = 5.1234;
System.out.println(r); // r is 5.1234

int decimalPlaces = 2;
BigDecimal bd = new BigDecimal(r);

// setScale is immutable
bd = bd.setScale(decimalPlaces, BigDecimal.ROUND_HALF_UP);
r = bd.doubleValue();

System.out.println(r); // r is 5.12

f = (float) (Math.round(n*100.0f)/100.0f);

DecimalFormat df2 = new DecimalFormat( "#,###,###,##0.00" );
double dd = 100.2397;
double dd2dec = new Double(df2.format(dd)).doubleValue();

// The value of dd2dec will be 100.24

The DecimalFormat() seems to be the most dynamic way to do it, and it is also very easy to understand when reading others code.

Another alternative (other than binary operators suggested by @jm-) is to use ng-switch:

<span ng-switch on="interface">
   <img ng-switch-when="UP" src='green-checkmark.png'>
   <img ng-switch-default   src='big-black-X.png'>
</span>

ng-switch will likely be better/easier if you have more than two images.

You can use the following code inside the style tag:

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
/* IE10+ specific styles go here */  
}

Below is an example that worked for me:

<style type="text/css">

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
   /* IE10+ specific styles go here */  
   #flashvideo {
        width:320px;
        height:240;
        margin:-240px 0 0 350px;
        float:left;
    }

    #googleMap {
        width:320px;
        height:240;
        margin:-515px 0 0 350px;
        float:left;
        border-color:#000000;
    }
}

#nav li {
    list-style:none;
    width:240px;
    height:25px;
    }

#nav a {
    display:block;
    text-indent:-5000px;
    height:25px;
    width:240px;
    }
</style>

Please note that since (#nav li) and (#nav a) are outside of the @media screen ..., they are general styles.

Yep, just add the following function to your Utils class or something:

    public static string cleanForJSON(string s)
    {
        if (s == null || s.Length == 0) {
            return "";
        }

        char         c = '\0';
        int          i;
        int          len = s.Length;
        StringBuilder sb = new StringBuilder(len + 4);
        String       t;

        for (i = 0; i < len; i += 1) {
            c = s[i];
            switch (c) {
                case '\\':
                case '"':
                    sb.Append('\\');
                    sb.Append(c);
                    break;
                case '/':
                    sb.Append('\\');
                    sb.Append(c);
                    break;
                case '\b':
                    sb.Append("\\b");
                    break;
                case '\t':
                    sb.Append("\\t");
                    break;
                case '\n':
                    sb.Append("\\n");
                    break;
                case '\f':
                    sb.Append("\\f");
                    break;
                case '\r':
                    sb.Append("\\r");
                    break;
                default:
                    if (c < ' ') {
                        t = "000" + String.Format("X", c);
                        sb.Append("\\u" + t.Substring(t.Length - 4));
                    } else {
                        sb.Append(c);
                    }
                    break;
            }
        }
        return sb.ToString();
    }

For what it worth, if anyone has this problem only in VSCode, just restart VSCode and it should fix it. Sometimes, Intellisense seems to mess up with imports or types.

Related to Typescript: Argument of type 'RegExpMatchArray' is not assignable to parameter of type 'string'

.toDate did not really work for me, So, Here is what i did :

futureStartAtDate = new Date(moment().locale("en").add(1, 'd').format("MMM DD, YYYY HH:MM"))

hope this helps

Try this:

const strippedString = htmlString.replace(/(<([^>]+)>)/gi, "");
console.log(strippedString);

I ran into this in a Web App on Azure when attempting to connect to Blob Storage. The problem turned out to be that I had missed deploying a connection string for the blob storage so it was still pointing at the storage emulator. There must be some retry logic built into the client because I saw about 3 attempts. The /devstorageaccount1 here is a dead giveaway.

Fixed by properly setting the connection string in Azure.

If you are using Visual Studio 2017 and come across this question, you might consider AxoCover. It's a free VS extension that integrates OpenCover, but supports VS2017 (it also appears to be under active development. +1).

You should remove "style" attribute instead of "display" property :

$("span").removeAttr("style");

This can be scripted in PL/SQL pretty simply based on the DBA/ALL/USER_CONSTRAINTS system view, but various details make not as trivial as it sounds. You have to be careful about the order in which it is done and you also have to take account of the presence of unique indexes.

The order is important because you cannot drop a unique or primary key that is referenced by a foreign key, and there could be foreign keys on tables in other schemas that reference primary keys in your own, so unless you have ALTER ANY TABLE privilege then you cannot drop those PKs and UKs. Also you cannot switch a unique index to being a non-unique index so you have to drop it in order to drop the constraint (for this reason it's almost always better to implement unique constraints as a "real" constraint that is supported by a non-unique index).

change layout weight according you will get....

Enter this:

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight="0.03">
    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:scaleType="centerInside"
        android:layout_gravity="center"
        android:src="@drawable/logo" />

</LinearLayout>

I think it really depends on why this error is given. It may be the bitness issue, but it may also be because of a deinstaller bug that leaves registry entries behind.

I just had this case because I need two versions of Python on my system. When I tried to install SCons (using Python2), the .msi installer failed, saying it only found Python3 in the registry. So I uninstalled it, with the result that no Python was found at all. Frustrating! (workaround: install SCons with pip install --egg --upgrade scons)

Anyway, I'm sure there are threads on that phenomenon. I just thought it would fit here because this was one of my top search results.

If you use constraints (and so don't have the frame sizes) then you can add a border view with the required constraints

// MARK: - Add a border to one side of a view

public enum BorderSide {
    case top, bottom, left, right
}

extension UIView {
    public func addBorder(side: BorderSide, color: UIColor, width: CGFloat) {
        let border = UIView()
        border.translatesAutoresizingMaskIntoConstraints = false
        border.backgroundColor = color
        self.addSubview(border)

        let topConstraint = topAnchor.constraint(equalTo: border.topAnchor)
        let rightConstraint = trailingAnchor.constraint(equalTo: border.trailingAnchor)
        let bottomConstraint = bottomAnchor.constraint(equalTo: border.bottomAnchor)
        let leftConstraint = leadingAnchor.constraint(equalTo: border.leadingAnchor)
        let heightConstraint = border.heightAnchor.constraint(equalToConstant: width)
        let widthConstraint = border.widthAnchor.constraint(equalToConstant: width)


        switch side {
        case .top:
            NSLayoutConstraint.activate([leftConstraint, topConstraint, rightConstraint, heightConstraint])
        case .right:
            NSLayoutConstraint.activate([topConstraint, rightConstraint, bottomConstraint, widthConstraint])
        case .bottom:
            NSLayoutConstraint.activate([rightConstraint, bottomConstraint, leftConstraint, heightConstraint])
        case .left:
            NSLayoutConstraint.activate([bottomConstraint, leftConstraint, topConstraint, widthConstraint])
        }
    }
}

Then set it something like the below

myButton.addBorder(side: .left, color: UIColor.lightGray, width: 1)

If you actually have set a root password and you've just lost/forgotten it:

1. Stop MySQL

2. Restart it manually with the skip-grant-tables option: mysqld_safe --skip-grant-tables

3. Now, open a new terminal window and run the MySQL client: mysql -u root

4. Reset the root password manually with this MySQL command: UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root'; If you are using MySQL 5.7 (check using mysql --version in the Terminal) then the command is:

   UPDATE mysql.user SET authentication_string=PASSWORD('password')  WHERE  User='root';
   

5. Flush the privileges with this MySQL command: FLUSH PRIVILEGES;

If you're open to using AWK:

awk '/textstring/ {print FNR}' textfile

In this case, FNR is the line number. AWK is a great tool when you're looking at grep|cut, or any time you're looking to take grep output and manipulate it.

If you need a cross-platform solution, try Boost's Program Options library.

You should use the location.reload(true), which will release the cache for that specific page and force the page to load as a NEW page.

The true parameter forces the page to release it's cache.

Reverse the string and check if original string and reverse are same or not

As described by Gideon, this is a known issue with Chrome that has been open for more than 5 years with no apparent interest in fixing it.

Unfortunately, in my case, the window.onunload = function() { debugger; } workaround didn't work either. So far the best workaround I've found is to use Firefox, which does display response data even after a navigation. The Firefox devtools also have a lot of nice features missing in Chrome, such as syntax highlighting the response data if it is html and automatically parsing it if it is JSON.

From my understanding, router.navigate is used to navigate relatively to current path. For eg : If our current path is abc.com/user, we want to navigate to the url : abc.com/user/10 for this scenario we can use router.navigate .

router.navigateByUrl() is used for absolute path navigation.

ie,

If we need to navigate to entirely different route in that case we can use router.navigateByUrl

For example if we need to navigate from abc.com/user to abc.com/assets, in this case we can use router.navigateByUrl()

Syntax :

router.navigateByUrl(' ---- String ----');

router.navigate([], {relativeTo: route})

You could search for:

<li><a href="#">[^\n]+

And replace with:

$0</a>

Where $0 is the whole match. The exact semantics will depend on the language are you using though.

WARNING: You should avoid parsing HTML with regex. Here's why.

Use of finishAffinity() may be an good option if you want to close all Activity of the app. As per the Android Docs-

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

The excellent case to use the regex:

" this is    wrong contained teee xt     "
    .replacingOccurrences(of: "^\\s+|\\s+|\\s+$", 
                          with: "", 
                          options: .regularExpression)

You can let PHP do a POST, but then your php will get the return, with all sorts of complications. I think the simplest would be to actually let the user do the POST.

So, kind-of what you suggested, you'll get indeed this part:

Customer fill detail in Page A, then in Page B we create another page show all the customer detail there, click a CONFIRM button then POST to Page C.

But you can actually do a javascript submit on page B, so there is no need for a click. Make it a "redirecting" page with a loading animation, and you're set.

Depending on your version:

Python 2.x:

for key, val in PIX0.iteritems():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

Python 3.x:

for key, val in PIX0.items():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

You should also get in the habit of using the new string formatting syntax ({} instead of % operator) from PEP 3101:

https://www.python.org/dev/peps/pep-3101/

Get a date object from the jquery date picker using

var myDate = $('element').datepicker('getDate')

For mysql the date needs to be in the proper format. One option which handles any timezone issues is to use moment.js

moment(myDate).format('YYYY-MM-DD HH:mm:ss')

You can use df.plot.scatter, and pass an array to c= argument defining the color of each point:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
colors = np.where(df["key1"]==4,'r','-')
colors[df["key1"]==6] = 'g'
colors[df["key1"]==8] = 'b'
print(colors)
df.plot.scatter(x="one",y="two",c=colors)
plt.show()

Ran into this issue while trying to create an index on a perfectly valid database. Turns out it will throw this error (in addition to other reasons described here) if the sqlite temp_store_directory variable/directory is unwritable.

Solution: change temp_store_directory with c.execute(f'PRAGMA temp_store_directory = "{writable_directory}"'). Note that this pragma is being deprecated and I am not yet sure what the replacement will be.

Note: This answer refers/adds to Sotirios Delimanolis's answer and comment.

I tried to get it to work with Map<Class, ParameterizedTypeReference<ResponseWrapper<?>>>, as indicated in Sotirios's comment, but couldn't without an example.

In the end, I dropped the wildcard and parametrisation from ParameterizedTypeReference and used raw types instead, like so

Map<Class<?>, ParameterizedTypeReference> typeReferences = new HashMap<>();
typeReferences.put(MyClass1.class, new ParameterizedTypeReference<ResponseWrapper<MyClass1>>() { });
typeReferences.put(MyClass2.class, new ParameterizedTypeReference<ResponseWrapper<MyClass2>>() { });

...

ParameterizedTypeReference typeRef = typeReferences.get(clazz);

ResponseEntity<ResponseWrapper<T>> response = restTemplate.exchange(
        uri, 
        HttpMethod.GET, 
        null, 
        typeRef);

and this finally worked.

If anyone has an example with parametrisation, I'd be very grateful to see it.

In my case, I only had read access to the .git/FETCH_HEAD file. I had to do "sudo chmod g+w .git/FETCH_HEAD" in order to be able to do a pull request.

bundle exec rake db:rollback    
rails destroy model <model_name>

When you generate a model, it creates a database migration. If you run 'destroy' on that model, it will delete the migration file, but not the database table. So before run

bundle exec rake db:rollback

• First, extract the ID of your desire file from google drive:

  1. In your browser, navigate to drive.google.com.

  2. Right-click on the file, and click "Get a shareable link"

     

  3. Then extract the ID of the file from URL:

     

• Next, install gdown PyPI module using pip:

  pip install gdown

• Finally, download the file using gdown and the intended ID:

  gdown --id <put-the-ID>

[NOTE]:

• In google-colab you have to use ! before bash commands.
  (i.e. !gdown --id 1-1wAx7b-USG0eQwIBVwVDUl3K1_1ReCt)

The simplest workaround I've found looks like this:

* * * * * root su -l -c command

This example invokes su as root user and starts the shell with the user's full environment, including $PATH, set as if they were logged in. It works the same on different distros, is more reliable than sourcing .bashrc (which hasn't worked for me) and avoids hardcoding specific paths which can be a problem if you're providing an example or setup tool and don't know what distro or file layout on the user's system.

You can also specify the username after su if you want a different user than root, but you should probably leave the root parameter before su command since this ensures su has sufficient privileges to switch to any user you specify.

Use mysqlimport to load a table into the database:

mysqlimport --ignore-lines=1 \
            --fields-terminated-by=, \
            --local -u root \
            -p Database \
             TableName.csv

I found it at http://chriseiffel.com/everything-linux/how-to-import-a-large-csv-file-to-mysql/

To make the delimiter a tab, use --fields-terminated-by='\t'

To extend Sean's great and concise answer with some sugar and modern syntax:

// date.js

const getMonthName = (num) => {
  const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Oct', 'Nov', 'Dec'];
  return months[num];
};

const formatDate = (d) => {
  const date = new Date(d);
  const year = date.getFullYear();
  const month = getMonthName(date.getMonth());
  const day = ('0' + date.getDate()).slice(-2);
  const hour = ('0' + date.getHours()).slice(-2);
  const minutes = ('0' + date.getMinutes()).slice(-2);

  return `${year} ${month} ${day}, ${hour}:${minutes}`;
};

module.exports = formatDate;

Then eg.

import formatDate = require('./date');

const myDate = "2018-07-24T13:44:46.493Z"; // Actual value from wherever, eg. MongoDB date
console.log(formatDate(myDate)); // 2018 Jul 24, 13:44

I have nothing against:

Array.apply(null, Array(5)).map(Number.prototype.valueOf,0);
new Array(5+1).join('0').split('').map(parseFloat);

suggested by Zertosh, but in a new ES6 array extensions allow you to do this natively with fill method. Now IE edge, Chrome and FF supports it, but check the compatibility table

new Array(3).fill(0) will give you [0, 0, 0]. You can fill the array with any value like new Array(5).fill('abc') (even objects and other arrays).

On top of that you can modify previous arrays with fill:

arr = [1, 2, 3, 4, 5, 6]
arr.fill(9, 3, 5)  # what to fill, start, end

which gives you: [1, 2, 3, 9, 9, 6]

I am answering this old question just because it still shows up in google queries and I think one optimal answer is missing. Try this code: use ::before or ::after

See Align <hr> to the left in an HTML5-compliant way

just return true inside your if statement

var myArr = [1,2,3,4];

myArr.forEach(function(elem){
  if (elem === 3) {

      return true;

    // Go to "next" iteration. Or "continue" to next iteration...
  }

  console.log(elem);
});

I used start /b for this instead of just start and it ran without a window for each command, so there was no waiting.

Kotlin: (If anyone needs)

var mText = text.substring(0, text.length.coerceAtMost(20))

If you take a look at the sources for django.contrib.auth.views.password_reset you'll see that it uses RequestContext. The upshot is, you can use Context Processors to modify the context which may allow you to inject the information that you need.

The b-list has a good introduction to context processors.

Edit (I seem to have been confused about what the actual question was):

You'll notice that password_reset takes a named parameter called template_name:

def password_reset(request, is_admin_site=False, 
            template_name='registration/password_reset_form.html',
            email_template_name='registration/password_reset_email.html',
            password_reset_form=PasswordResetForm, 
            token_generator=default_token_generator,
            post_reset_redirect=None):

Check password_reset for more information.

... thus, with a urls.py like:

from django.conf.urls.defaults import *
from django.contrib.auth.views import password_reset

urlpatterns = patterns('',
     (r'^/accounts/password/reset/$', password_reset, {'template_name': 'my_templates/password_reset.html'}),
     ...
)

django.contrib.auth.views.password_reset will be called for URLs matching '/accounts/password/reset' with the keyword argument template_name = 'my_templates/password_reset.html'.

Otherwise, you don't need to provide any context as the password_reset view takes care of itself. If you want to see what context you have available, you can trigger a TemplateSyntax error and look through the stack trace find the frame with a local variable named context. If you want to modify the context then what I said above about context processors is probably the way to go.

In summary: what do you need to do to use your own template? Provide a template_name keyword argument to the view when it is called. You can supply keyword arguments to views by including a dictionary as the third member of a URL pattern tuple.

The aim of using StringBuilder, i.e reducing memory. Is it achieved?

No, not at all. That code is not using StringBuilder correctly. (I think you've misquoted it, though; surely there aren't quotes around id2 and table?)

Note that the aim (usually) is to reduce memory churn rather than total memory used, to make life a bit easier on the garbage collector.

Will that take memory equal to using String like below?

No, it'll cause more memory churn than just the straight concat you quoted. (Until/unless the JVM optimizer sees that the explicit StringBuilder in the code is unnecessary and optimizes it out, if it can.)

If the author of that code wants to use StringBuilder (there are arguments for, but also against; see note at the end of this answer), better to do it properly (here I'm assuming there aren't actually quotes around id2 and table):

StringBuilder sb = new StringBuilder(some_appropriate_size);
sb.append("select id1, ");
sb.append(id2);
sb.append(" from ");
sb.append(table);
return sb.toString();

Note that I've listed some_appropriate_size in the StringBuilder constructor, so that it starts out with enough capacity for the full content we're going to append. The default size used if you don't specify one is 16 characters, which is usually too small and results in the StringBuilder having to do reallocations to make itself bigger (IIRC, in the Sun/Oracle JDK, it doubles itself [or more, if it knows it needs more to satisfy a specific append] each time it runs out of room).

You may have heard that string concatenation will use a StringBuilder under the covers if compiled with the Sun/Oracle compiler. This is true, it will use one StringBuilder for the overall expression. But it will use the default constructor, which means in the majority of cases, it will have to do a reallocation. It's easier to read, though. Note that this is not true of a series of concatenations. So for instance, this uses one StringBuilder:

return "prefix " + variable1 + " middle " + variable2 + " end";

It roughly translates to:

StringBuilder tmp = new StringBuilder(); // Using default 16 character size
tmp.append("prefix ");
tmp.append(variable1);
tmp.append(" middle ");
tmp.append(variable2);
tmp.append(" end");
return tmp.toString();

So that's okay, although the default constructor and subsequent reallocation(s) isn't ideal, the odds are it's good enough — and the concatenation is a lot more readable.

But that's only for a single expression. Multiple StringBuilders are used for this:

String s;
s = "prefix ";
s += variable1;
s += " middle ";
s += variable2;
s += " end";
return s;

That ends up becoming something like this:

String s;
StringBuilder tmp;
s = "prefix ";
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable1);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" middle ");
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable2);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" end");
s = tmp.toString();
return s;

...which is pretty ugly.

It's important to remember, though, that in all but a very few cases it doesn't matter and going with readability (which enhances maintainability) is preferred barring a specific performance issue.

It doesn't always need to be toolkit-dependent or one doesn't always need use the FontMetrics approach since it requires one to first obtain a graphics object which is absent in a web container or in a headless enviroment.

I have tested this in a web servlet and it does calculate the text width.

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

...

String text = "Hello World";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);     
Font font = new Font("Tahoma", Font.PLAIN, 12);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());

Add the necessary values to these dimensions to create any required margin.

In Windows xp sp3 you can use sleep command

1) Locate the my.ini, which store in the MySQL installation folder.

For example,

C:\Program Files\MySQL\MySQL Server 5.1\my.ini

2) Open the “my.ini” with our favor text editor.

#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.1/"

#Path to the database root/"
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data

Find the “datadir”, this is the where does MySQL stored the data in Windows.

If you want to catch the focus event dynamiclly on every input on your component :

import { AfterViewInit, Component, ElementRef } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements AfterViewInit {

  constructor(private el: ElementRef) {
  }

  ngAfterViewInit() {
       // document.getElementsByTagName('input') : to gell all Docuement imputs
       const inputList = [].slice.call((<HTMLElement>this.el.nativeElement).getElementsByTagName('input'));
        inputList.forEach((input: HTMLElement) => {
            input.addEventListener('focus', () => {
                input.setAttribute('placeholder', 'focused');
            });
            input.addEventListener('blur', () => {
                input.removeAttribute('placeholder');
            });
        });
    }
}

If you can not use it directly and if you encounter this error: Blocked a frame with origin "http://www..com" from accessing a cross-origin frame. You can use postMessage() instead of using the function directly.

Place the following in the CODE MODULE of a WORKSHEET to track the last value for every cell in the used range:

Option Explicit

Private r As Range
Private Const d = "||"

Public Function ValueLast(r As Range)
    On Error Resume Next
    ValueLast = Split(r.ID, d)(1)
End Function

Private Sub Worksheet_Activate()
    For Each r In Me.UsedRange: Record r: Next
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
    For Each r In Target: Record r: Next
End Sub

Private Sub Record(r)
    r.ID = r.Value & d & Split(r.ID, d)(0)
End Sub

And that's it.

This solution uses the obscure and almost never used Range.ID property, which allows the old values to persist when the workbook is saved and closed.

At any time you can get at the old value of a cell and it will indeed be different than a new current value:

With Sheet1
    MsgBox .[a1].Value
    MsgBox .ValueLast(.[a1])
End With

I have spent two solid days working on this so I just thought I'd share my solution as well. As of 26/11/10 the current branch is 1.2.X so that means you'll have to have the following in you settings.py:

MEDIA_ROOT = "<path_to_files>" (i.e. /home/project/django/app/templates/static)
MEDIA_URL = "http://localhost:8000/static/"

*(remember that MEDIA_ROOT is where the files are and MEDIA_URL is a constant that you use in your templates.)*

Then in you url.py place the following:

import settings

# stuff

(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),

Then in your html you can use:

<img src="{{ MEDIA_URL }}foo.jpg">

The way django works (as far as I can figure is:

1. In the html file it replaces MEDIA_URL with the MEDIA_URL path found in setting.py
2. It looks in url.py to find any matches for the MEDIA_URL and then if it finds a match (like r'^static/(?P.)$'* relates to http://localhost:8000/static/) it searches for the file in the MEDIA_ROOT and then loads it

Well, my code is like yours, with little diferences...

You can do it using Primefaces like this :

<p:button 
      outcome="/page2.xhtml?faces-redirect=true&amp;id=#{myBean.id}">
</p:button>

Not possible, but you can do:

float f;
int i;
for (i = 0,f = 0.0; i < 5; i++)
{
  //...
}

Or, explicitly limit the scope of f and i using additional brackets:

{
    float f; 
    int i;
    for (i = 0,f = 0.0; i < 5; i++)
    {
       //...
    }
}

I simply had to add -h localhost

I had the same issue. Fistly, thats what i have :

1. win 10
2. xampp
3. git bash

and i have done this to fix my problem :

1. go to search box(PC)
2. tape this environnement variable
3. go to 'path' click 'edit'
4. add this "%systemDrive%\xampp\mysql\bin\" C:\xampp\mysql\bin\
5. click ok
6. go to Git Bash and right click it and open it and run as administrator
7. right this on your Git Bash winpty mysql -u root if your password is empty or winpty mysql -u root -p if you do have a password

There is another option that does not introduce global gotchas when trying to initialize multiple variables to the same value. Whether or not it is preferable to the long way is a judgement call. It will likely be slower and may or may not be more readable. In your specific case, I think that the long way is probably more readable and maintainable as well as being faster.

The other way utilizes Destructuring assignment.

let [moveUp, moveDown,_x000D_
     moveLeft, moveRight,_x000D_
     mouseDown, touchDown] = Array(6).fill(false);_x000D_
_x000D_
console.log(JSON.stringify({_x000D_
    moveUp, moveDown,_x000D_
    moveLeft, moveRight,_x000D_
    mouseDown, touchDown_x000D_
}, null, '  '));_x000D_
_x000D_
// NOTE: If you want to do this with objects, you would be safer doing this_x000D_
let [obj1, obj2, obj3] = Array(3).fill(null).map(() => ({}));_x000D_
console.log(JSON.stringify({_x000D_
    obj1, obj2, obj3_x000D_
}, null, '  '));_x000D_
// So that each array element is a unique object_x000D_
_x000D_
// Or another cool trick would be to use an infinite generator_x000D_
let [a, b, c, d] = (function*() { while (true) yield {x: 0, y: 0} })();_x000D_
console.log(JSON.stringify({_x000D_
    a, b, c, d_x000D_
}, null, '  '));_x000D_
_x000D_
// Or generic fixed generator function_x000D_
function* nTimes(n, f) {_x000D_
    for(let i = 0; i < n; i++) {_x000D_
        yield f();_x000D_
    }_x000D_
}_x000D_
let [p1, p2, p3] = [...nTimes(3, () => ({ x: 0, y: 0 }))];_x000D_
console.log(JSON.stringify({_x000D_
    p1, p2, p3_x000D_
}, null, '  '));

This allows you to initialize a set of var, let, or const variables to the same value on a single line all with the same expected scope.

This will work:

tr:hover {
    background: #000 !important;
}

If you want to only apply bg-color on TD then:

tr:hover td {
    background: #c7d4dd !important;
}

It will even overwrite your given color and apply this forcefully.

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

There are different regex engines but I think most of them will work with this:

Open a connection to your server first (SQL IDE) from the home screen. Then use the context menu in the schema tree to run a query that simply selects rows from the selected table. The LIMIT attached to that is to avoid reading too many rows by accident. This limit can be switched off (or adjusted) in the preferences dialog.

This quick way to select rows is however not very flexible. Normally you would run a query (File / New Query Tab) in the editor with additional conditions, like a sort order:

What you have should work but can be reduced to:

select * from table where concat_ws(' ',first_name,last_name) 
like '%$search_term%';

Can you provide an example name and search term where this doesn't work?

This worked for me!!

SELECT * FROM `users` where `created_at` BETWEEN CURDATE()-7 AND CURDATE()

If you're going across machines, you either need to be using NETWORK SERVICE, LOCAL SYSTEM, a domain account, or a SQL 2008 R2 (if you have it) Managed Service Account (which is my preference if you had such an infrastructure). You can not use an account which is not visible to the Active Directory domain.

I wanted to answer here because NONE of these answers, or any other Google result solved the issue for me.

For me it had nothing to do with fieldsets or hidden inputs.

I found that if I used max="5" (e.g.) it would produce this error. If I used maxlength="5" ... no error.

I was able to reproduce the error and clearing of error several times.

I still do not know why using that code produces the error, as far as this states it should be valid, even without a "min" I believe.

string[] files = 
    Directory.GetFiles(txtPath.Text, "*ProfileHandler.cs", SearchOption.AllDirectories);

That last parameter effects exactly what you're referring to. Set it to AllDirectories for every file including in subfolders, and set it to TopDirectoryOnly if you only want to search in the directory given and not subfolders.

Refer to MDSN for details: https://msdn.microsoft.com/en-us/library/ms143316(v=vs.110).aspx

In a Form, Create a text box, with in text box properties select data tab

Default value =CurrentUser()

Current source "select table field name"

It will display current user log on name in text box / label as well as saves the user name in the table field

If you have a single play that you want to loop over the items, define that list in group_vars/all or somewhere else that makes sense:

all_items:
  - first
  - second
  - third
  - fourth

Then your task can look like this:

  - name: List items or default list
    debug:
      var: item
    with_items: "{{ varlist | default(all_items) }}"

Pass in varlist as a JSON array:

ansible-playbook <playbook_name> --extra-vars='{"varlist": [first,third]}'

Prior to that, you might also want a task that checks that each item in varlist is also in all_items:

  - name: Ensure passed variables are in all_items
    fail:
      msg: "{{ item }} not  in all_items list"
    when: item not in all_items
    with_items: "{{ varlist | default(all_items) }}"

When clearing out a Solr index, you should also do a commit and optimize after running the delete-all query. Full steps required (curl is all you need): http://www.alphadevx.com/a/365-Clearing-a-Solr-search-index

parseInt converts to a integer number, that is, it strips decimals. Number does not convert to integer.

I got this error but it is resolved interesting. As first, i got this error at api level 17. When i call a thread (AsyncTask or others) without progress dialog then i call an other thread method again using progress dialog, i got that crash and the reason is about usage of progress dialog.

In my case, there are two results that;

• I took show(); method of progress dialog before first thread starts then i took dismiss(); method of progress dialog before last thread ends.

So :

ProgresDialog progressDialog = new ...

//configure progressDialog 

progressDialog.show();

start firstThread {
...
}

...

start lastThread {
...
} 

//be sure to finish threads

progressDialog.dismiss();

• This is so strange but that error has an ability about destroy itself at least for me :)

I had the same problem. I solve it with a for loop.

Example:

If I want to write in 2 identical tables, using a loop

for x = 0 to 1

 if x = 0 then TableToWrite = "Table1"
 if x = 1 then TableToWrite = "Table2"
  Sql = "INSERT INTO " & TableToWrite & " VALUES ('1','2','3')"
NEXT

either

ArrTable = ("Table1", "Table2")

for xArrTable = 0 to Ubound(ArrTable)
 Sql = "INSERT INTO " & ArrTable(xArrTable) & " VALUES ('1','2','3')"
NEXT

If you have a small query I don't know if this is the best solution, but if you your query is very big and it is inside a dynamical script with if/else/case conditions this is a good solution.

Disclaimer: This solution should only be used for data at rest that is not exposed to the public (for example - a configuration file or DB). Only in this scenario, the quick-and-dirty solution can be considered better than @jbtule's solution, due to lower maintanance.

Original post: I found jbtule's answer a bit complicated for a quick and dirty secured AES string encryption and Brett's answer had a bug with the Initialization Vector being a fixed value making it vulnerable to padding attacks, so I fixed Brett's code and added a random IV that is added to the chipered string, creating a different encrypted value each and every encryption of the same value:

Encryption:

public static string Encrypt(string clearText)
{            
    byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
    using (Aes encryptor = Aes.Create())
    {
        byte[] IV = new byte[15];
        rand.NextBytes(IV);
        Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, IV);
        encryptor.Key = pdb.GetBytes(32);
        encryptor.IV = pdb.GetBytes(16);
        using (MemoryStream ms = new MemoryStream())
        {
            using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateEncryptor(), CryptoStreamMode.Write))
            {
                cs.Write(clearBytes, 0, clearBytes.Length);
                cs.Close();
            }
            clearText = Convert.ToBase64String(IV) + Convert.ToBase64String(ms.ToArray());
        }
    }
    return clearText;
}

Decryption:

public static string Decrypt(string cipherText)
{
    byte[] IV = Convert.FromBase64String(cipherText.Substring(0, 20));
    cipherText = cipherText.Substring(20).Replace(" ", "+");
    byte[] cipherBytes = Convert.FromBase64String(cipherText);
    using (Aes encryptor = Aes.Create())
    {
        Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(EncryptionKey, IV);
        encryptor.Key = pdb.GetBytes(32);
        encryptor.IV = pdb.GetBytes(16);
        using (MemoryStream ms = new MemoryStream())
        {
            using (CryptoStream cs = new CryptoStream(ms, encryptor.CreateDecryptor(), CryptoStreamMode.Write))
            {
                cs.Write(cipherBytes, 0, cipherBytes.Length);
                cs.Close();
            }
            cipherText = Encoding.Unicode.GetString(ms.ToArray());
        }
    }
    return cipherText;
}

Replace EncryptionKey with your key. In my implementation, the key is being saved in the configuration file (web.config\app.config) as you shouldn't save it hard coded. The configuration file should be also encrypted so the key won't be saved as clear text in it.

protected static string _Key = "";
protected static string EncryptionKey
{
    get
    {
        if (String.IsNullOrEmpty(_Key))
        {
            _Key = ConfigurationManager.AppSettings["AESKey"].ToString();
        }

        return _Key;
    }
}

To escape ' you simly need to put another before: ''

As the second answer shows it's possible to escape single quote like this:

select 'it''s escaped'

result will be

it's escaped

If you're concatenating SQL into a VARCHAR to execute (i.e. dynamic SQL), then I'd recommend parameterising the SQL. This has the benefit of helping guard against SQL injection plus means you don't have to worry about escaping quotes like this (which you do by doubling up the quotes).

e.g. instead of doing

DECLARE @SQL NVARCHAR(1000)
SET @SQL = 'SELECT * FROM MyTable WHERE Field1 = ''AAA'''
EXECUTE(@SQL)

try this:

DECLARE @SQL NVARCHAR(1000)
SET @SQL = 'SELECT * FROM MyTable WHERE Field1 = @Field1'
EXECUTE sp_executesql @SQL, N'@Field1 VARCHAR(10)', 'AAA'

I suggest create a list and append dictionary into it.

x   = []
cur = db.dbname.find()
for i in cur:
    x.append(i)
print(x)

Now x is a list of dictionary, you can manipulate the same in usual python way.

Looks like there is an issue with the code you posted. Your function to display the T&C is referencing the wrong div id. You should consider assigning the showTOC function to the onclick attribute once the document is loaded as well:

$(document).ready({
    $('a.TOClink').click(function(){
        showTOC();
    });
});

function showTOC() {
    $('#example').dialog({modal:true});
}

A more concise example which accomplishes the desired effect using the jQuery UI dialog is:

   <div id="terms" style="display:none;">
       Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
   </div>
   <a id="showTerms" href="#">Show Terms &amp; Conditions</a>      
   <script type="text/javascript">
       $(document).ready(function(){
           $('#showTerms').click(function(){
               $('#terms').dialog({modal:true});   
           });
       });
   </script>

If you only want to remove columns 5 and 7 but not 6 try:

album2 <- album2[,-c(5,7)] #deletes columns 5 and 7
