Add produces = "application/json" in @RequestMapping

Pattern p = Pattern.compile("tom"); //the regular-expression pattern
Matcher m = p.matcher("(bob)(tom)(harry)"); //The data to find matches with

while (m.find()) {
    //do something???
}   

Use regex to find a match maybe?

Or create an array

 String[] a = new String[]{
        "tom",
        "bob",
        "harry"
 };

 if(a.contains(stringtomatch)){
     //do something
 }

bool Compare(T x, T y) where T : class { return x == y; }

The above will work because == is taken care of in case of user-defined reference types.
In case of value types, == can be overridden. In which case, "!=" should also be defined.

I think that could be the reason, it disallows generic comparison using "==".

Add -lm to your link options, since pow() and floor() are part of the math library:

gcc fib.c -o fibo -lm

It is open-source, and available at http://codeplex.com/elephant

Some one’s made a working example of the gpg6-code, you can find it here: http://www.unseen-academy.de/componentSystem.html

You can use rextract to extract using a regular expression and reformat the result.

Example:

[$] echo "12 BBQ ,45 rofl, 89 lol" | ./rextract '[,]([\d]+) rofl' '${1}'
45

It is worth mentioning that 2>&1 means that standard error will be redirected too, together with standard output. So

someCommand | tee someFile

gives you just the standard output in the file, but not the standard error: standard error will appear in console only. To get standard error in the file too, you can use

someCommand 2>&1 | tee someFile

(source: In the shell, what is " 2>&1 "? ). Finally, both the above commands will truncate the file and start clear. If you use a sequence of commands, you may want to get output&error of all of them, one after another. In this case you can use -a flag to "tee" command:

someCommand 2>&1 | tee -a someFile

<%
    String redirectURL = "http://whatever.com/myJSPFile.jsp";
    response.sendRedirect(redirectURL);
%>

As of iOS 9.0 there's no way to get the orientation reliably. This is the code I used for an app I design for only portrait mode, so if the app is opened in landscape mode it will still be accurate:

screenHeight = [[UIScreen mainScreen] bounds].size.height;
screenWidth = [[UIScreen mainScreen] bounds].size.width;
if (screenWidth > screenHeight) {
    float tempHeight = screenWidth;
    screenWidth = screenHeight;
    screenHeight = tempHeight;
}

On Ubuntu until python-distribute is something newer than 0.7 I'd recommend:

$ wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python

See http://reinout.vanrees.org/weblog/2013/07/08/new-setuptools-buildout.html

I was also looking for a solution to this problem and as easy and comfortable I found, was to convert the shape of a rectangular TextView to cirular. With this method will be perfect:

1. Create a new XML file in the drawable folder called "circle.xml" (for example) and fill it with the following code:

   <shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="oval">
   
       <solid android:color="#9FE554" />
   
       <size
           android:height="60dp"
           android:width="60dp" />
   
   </shape>
   

With this file you will create the new form of TextView. In this case, I created a circle of green. If you want to add a border, you would have to add the following code to the previous file:

    <stroke
        android:width="2dp"
        android:color="#FFFFFF" />

2. Create another XML file ( "rounded_textview.xml") in the drawable folder with the following code:

   <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
       <item android:drawable="@drawable/circle" />
   </selector>
   

This file will serve to change the way the TextView we eligamos.

3. Finally, in the TextView properties we want to change the way section, we headed to the "background" and select the second XML file created ( "rounded_textview.xml").

   <TextView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="H"
       android:textSize="30sp"
       android:background="@drawable/rounded_textview"
       android:textColor="@android:color/white"
       android:gravity="center"
       android:id="@+id/mark" />
   

With these steps, instead of having a TextView TextView rectagular have a circular. Just change the shape, not the functionality of the TextView. The result would be the following:

Also I have to say that these steps can be applied to any other component having the option to "background" in the properties.

Luck!!

Try this complete and flexible solution. It works perfectly, and is based in-part by some previous answers, but contains additional validation checks, and gets rid of additional implied HTML from the loadHTML(...) function. It is divided into two separate functions (one with a previous dependency so don't re-order/rearrange) so you can use it with multiple HTML tags that you would like to remove simultaneously (i.e. not just 'script' tags). For example removeAllInstancesOfTag(...) function accepts an array of tag names, or optionally just one as a string. So, without further ado here is the code:

/* Remove all instances of a particular HTML tag (e.g. <script>...</script>) from a variable containing raw HTML data. [BEGIN] */

/* Usage Example: $scriptless_html = removeAllInstancesOfTag($html, 'script'); */

if (!function_exists('removeAllInstancesOfTag'))
    {
        function removeAllInstancesOfTag($html, $tag_nm)
            {
                if (!empty($html))
                    {
                        $html = mb_convert_encoding($html, 'HTML-ENTITIES', 'UTF-8'); /* For UTF-8 Compatibility. */
                        $doc = new DOMDocument();
                        $doc->loadHTML($html,LIBXML_HTML_NOIMPLIED|LIBXML_HTML_NODEFDTD|LIBXML_NOWARNING);

                        if (!empty($tag_nm))
                            {
                                if (is_array($tag_nm))
                                    {
                                        $tag_nms = $tag_nm;
                                        unset($tag_nm);

                                        foreach ($tag_nms as $tag_nm)
                                            {
                                                $rmvbl_itms = $doc->getElementsByTagName(strval($tag_nm));

                                                    };

                                                    };

                                else if (is_string($tag_nm))
                                    {
                                        $rmvbl_itms = $doc->getElementsByTagName($tag_nm);

                                                $itm->parentNode->removeChild($itm); 
                                            };
                                    };
                            };

                        return $doc->saveHTML();
                    }
                else
                    {
                        return '';

And here is a test usage example:

$html = 'This is a JavaScript retention test.<br><br><span id="chk_frst_scrpt">Congratulations! The first \'script\' tag was successfully removed!</span><br><br><span id="chk_secd_scrpt">Congratulations! The second \'script\' tag was successfully removed!</span><script>document.getElementById("chk_frst_scrpt").innerHTML = "Oops! The first \'script\' tag was NOT removed!";</script><script>document.getElementById("chk_secd_scrpt").innerHTML = "Oops! The second \'script\' tag was NOT removed!";</script>';
echo removeAllScriptTags($html);

I hope my answer really helps someone. Enjoy!

In the latest version of ggplot2, this can be more easy.

p <- ggplot(mtcars, aes(wt, mpg))
p + geom_point()
p+ geom_point() + scale_x_continuous(expand = expansion(mult = c(0, 0))) + scale_y_continuous(expand = expansion(mult = c(0, 0)))

See ?expansion() for more details.

use code like this:

new Guid("9D2B0228-4D0D-4C23-8B49-01A698857709")

instead of "9D2B0228-4D0D-4C23-8B49-01A698857709" you can set your string value

The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:

'save-json' => array(
'type' => 'Zend\Mvc\Router\Http\Segment',
            'options' => array(
                'route'    => '/save-json/',
                'defaults' => array(
                    'controller' => 'CDB\Controller\Index',
                    'action'     => 'save-json',
                ),
            ),
        ),

and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend

$this->params()->fromPost('paramname'); 

didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':

$content = file_get_contents('php://input');
print_r(json_decode($content));

I got my json array in the end. Hope this helps.

Use fully qualified class names for your log tags:

public class MyActivity extends Activity {
  private static final String TAG = MyActivity.class.getName();
}

Then

Log.i(TAG, "hi");

Then use grep

adb logcat | grep com.myapp

Java is a statically typed language, so the compiler does most of this checking for you. Once you declare a variable to be a certain type, the compiler will ensure that it is only ever assigned values of that type (or values that are sub-types of that type).

The examples you gave (int, array, double) these are all primitives, and there are no sub-types of them. Thus, if you declare a variable to be an int:

int x;

You can be sure it will only ever hold int values.

If you declared a variable to be a List, however, it is possible that the variable will hold sub-types of List. Examples of these include ArrayList, LinkedList, etc.

If you did have a List variable, and you needed to know if it was an ArrayList, you could do the following:

List y;
...
if (y instanceof ArrayList) { 
  ...its and ArrayList...
}

However, if you find yourself thinking you need to do that, you may want to rethink your approach. In most cases, if you follow object-oriented principles, you will not need to do this. There are, of course, exceptions to every rule, though.

Summary.

Can I nest git repositories?

Yes. However, by default git does not track the .git folder of the nested repository. Git has features designed to manage nested repositories (read on).

Does it make sense to git init/add the /project_root to ease management of everything locally or do I have to manage my_project and the 3rd party one separately?

It probably doesn't make sense as git has features to manage nested repositories. Git's built in features to manage nested repositories are submodule and subtree.

Here is a blog on the topic and here is a SO question that covers the pros and cons of using each.

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

Override the property isDefaultPrevented like this:

$('a').click(function(evt){
  evt.preventDefault();

  // in async handler (ajax/timer) do these actions:
  setTimeout(function(){
    // override prevented flag to prevent jquery from discarding event
    evt.isDefaultPrevented = function(){ return false; }
    // retrigger with the exactly same event data
    $(this).trigger(evt);
  }, 1000);
}

IMHO, this is most complete way of retriggering the event with the exactly same data.

This one helped me:

Getting started with .NET unit testing using NUnit

Basically:

• Add the NUnit 3 library in NuGet.
• Create the class you want to test.
• Create a separate testing class. This should have [TestFixture] above it.
• Create a function in the testing class. This should have [Test] above it.
• Then go into TEST/WINDOW/TEST EXPLORER (across the top).
• Click run to the left-hand side. It will tell you what has passed and what has failed.

My example code is here:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NUnit.Framework;

namespace NUnitTesting
{
    class Program
    {
        static void Main(string[] args)
        {
        }
    }

    public class Maths
    {
        public int Add(int a, int b)
        {
            int x = a + b;
            return x;
        }
    }

    [TestFixture]
    public class TestLogging
    {
        [Test]
        public void Add()
        {
            Maths add = new Maths();
            int expectedResult = add.Add(1, 2);
            Assert.That(expectedResult, Is.EqualTo(3));
        }
    }
}

This will return true, and if you change the parameter in Is.EqualTo it will fail, etc.

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

I came here and followed above answer. But mismatch in the Order of data type caused an error. The below description from another answer will come handy.

Are the results above the same as the sequence of columns in your table? because oracle is strict in column orders. this example below produces an error:

create table test1_1790 (
col_a varchar2(30),
col_b number,
col_c date);

create table test2_1790 (
col_a varchar2(30),
col_c date,
col_b number);

select * from test1_1790
union all
select * from test2_1790;

ORA-01790: expression must have same datatype as corresponding expression

As you see the root cause of the error is in the mismatching column ordering that is implied by the use of * as column list specifier. This type of errors can be easily avoided by entering the column list explicitly:

select col_a, col_b, col_c from test1_1790 union all select col_a, col_b, col_c from test2_1790; A more frequent scenario for this error is when you inadvertently swap (or shift) two or more columns in the SELECT list:

select col_a, col_b, col_c from test1_1790
union all
select col_a, col_c, col_b from test2_1790;

OR if the above does not solve your problem, how about creating an ALIAS in the columns like this: (the query is not the same as yours but the point here is how to add alias in the column.)

SELECT id_table_a, 
       desc_table_a, 
       table_b.id_user as iUserID, 
       table_c.field as iField
UNION
SELECT id_table_a, 
       desc_table_a, 
       table_c.id_user as iUserID, 
       table_c.field as iField

The answer above covers everything in great detail, apart from a couple of things.

First, if there are no styles, then the (Context context, AttributeSet attrs) method signature will be used to instantiate the preference. In this case just use context.obtainStyledAttributes(attrs, R.styleable.MyCustomView) to get the TypedArray.

Secondly it does not cover how to deal with plaurals resources (quantity strings). These cannot be dealt with using TypedArray. Here is a code snippet from my SeekBarPreference that sets the summary of the preference formatting its value according to the value of the preference. If the xml for the preference sets android:summary to a text string or a string resouce the value of the preference is formatted into the string (it should have %d in it, to pick up the value). If android:summary is set to a plaurals resource, then that is used to format the result.

// Use your own name space if not using an android resource.
final static private String ANDROID_NS = 
    "http://schemas.android.com/apk/res/android";
private int pluralResource;
private Resources resources;
private String summary;

public SeekBarPreference(Context context, AttributeSet attrs) {
    // ...
    TypedArray attributes = context.obtainStyledAttributes(
        attrs, R.styleable.SeekBarPreference);
    pluralResource =  attrs.getAttributeResourceValue(ANDROID_NS, "summary", 0);
    if (pluralResource !=  0) {
        if (! resources.getResourceTypeName(pluralResource).equals("plurals")) {
            pluralResource = 0;
        }
    }
    if (pluralResource ==  0) {
        summary = attributes.getString(
            R.styleable.SeekBarPreference_android_summary);
    }
    attributes.recycle();
}

@Override
public CharSequence getSummary() {
    int value = getPersistedInt(defaultValue);
    if (pluralResource != 0) {
        return resources.getQuantityString(pluralResource, value, value);
    }
    return (summary == null) ? null : String.format(summary, value);
}

• This is just given as an example, however, if you want are tempted to set the summary on the preference screen, then you need to call notifyChanged() in the preference's onDialogClosed method.

Try importing this in build.gradle dependencies

compile group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1'

If you are using Windows.Data.Xml.Dom.XmlDocument version of XmlDocument (used in UWP apps for example), you can use yourXmlDocument.GetXml() to get the XML as a string.

use sudo with the command:

sudo apt-get remove --purge mongodb  
apt-get autoremove --purge mongodb  

INDIRECT is the function you want to use. Like so:

=INDIRECT("'"&A5&"'!G7")

With INDIRECT you can build your formula as a text string.

On my Mac:

/System/Library/Frameworks/JavaVM.framework/Home/

btw, did you tried which java?

this works for me (Keltex said the same)

.foo {
height: 50px;
...
}
.foo span{
vertical-align: middle; 
}

<span class="foo"> <span>middle!</span></span>

You have 3 choices:

1. atoi

This is probably the fastest if you're using it in performance-critical code, but it does no error reporting. If the string does not begin with an integer, it will return 0. If the string contains junk after the integer, it will convert the initial part and ignore the rest. If the number is too big to fit in int, the behaviour is unspecified.

2. sscanf

Some error reporting, and you have a lot of flexibility for what type to store (signed/unsigned versions of char/short/int/long/long long/size_t/ptrdiff_t/intmax_t).

The return value is the number of conversions that succeed, so scanning for "%d" will return 0 if the string does not begin with an integer. You can use "%d%n" to store the index of the first character after the integer that's read in another variable, and thereby check to see if the entire string was converted or if there's junk afterwards. However, like atoi, behaviour on integer overflow is unspecified.

3. strtol and family

Robust error reporting, provided you set errno to 0 before making the call. Return values are specified on overflow and errno will be set. You can choose any number base from 2 to 36, or specify 0 as the base to auto-interpret leading 0x and 0 as hex and octal, respectively. Choices of type to convert to are signed/unsigned versions of long/long long/intmax_t.

If you need a smaller type you can always store the result in a temporary long or unsigned long variable and check for overflow yourself.

Since these functions take a pointer to pointer argument, you also get a pointer to the first character following the converted integer, for free, so you can tell if the entire string was an integer or parse subsequent data in the string if needed.

Personally, I would recommend the strtol family for most purposes. If you're doing something quick-and-dirty, atoi might meet your needs.

As an aside, sometimes I find I need to parse numbers where leading whitespace, sign, etc. are not supposed to be accepted. In this case it's pretty damn easy to roll your own for loop, eg.,

for (x=0; (unsigned)*s-'0'<10; s++) 
    x=10*x+(*s-'0');

Or you can use (for robustness):

if (isdigit(*s))
    x=strtol(s, &s, 10);
else /* error */ 

This works for me:

Apparently thanks to since this pull request: https://github.com/remy/nodemon/pull/1552

If you want to make the reverse of what you showed consider doing this:

.tint:hover:before {
    background: rgba(0,0,250, 0.5);

  }

  .t2:before {
    background: none;
  }

and look at the effect on the 2nd picture.

Is it supposed to look like this?

A limit on the number of open sockets is configurable in the /proc file system

cat /proc/sys/fs/file-max

Max for incoming connections in the OS defined by integer limits.

Linux itself allows billions of open sockets.

To use the sockets you need an application listening, e.g. a web server, and that will use a certain amount of RAM per socket.

RAM and CPU will introduce the real limits. (modern 2017, think millions not billions)

1 millions is possible, not easy. Expect to use X Gigabytes of RAM to manage 1 million sockets.

Outgoing TCP connections are limited by port numbers ~65000 per IP. You can have multiple IP addresses, but not unlimited IP addresses. This is a limit in TCP not Linux.

Similar to mangledorf's solution, but shorter and layman friendly

Same issue as in Error in launching AVD:

1) Install the Intel x86 Emulator Accelerator (HAXM installer) from the Android SDK Manager;

2) Run (for Windows):

{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

or (for OSX):

{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHAXM_1.1.1_for_10_9_and_above.dmg

3) Start the emulator.

Setting the following option:

set  disassemble-next-line on
show disassemble-next-line

Will give you results that look like this:

However having a simple git pull as a deployment process is usually a bad idea and should be avoided in favor of a real deployment script.

Instructions for finding MSBuild:

• PowerShell: &"${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -products * -requires Microsoft.Component.MSBuild -find MSBuild\**\Bin\MSBuild.exe
• CMD: "%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -products * -requires Microsoft.Component.MSBuild -find MSBuild\**\Bin\MSBuild.exe

Instructions for finding VSTest:

• PowerShell: &"${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -products * -requires Microsoft.VisualStudio.PackageGroup.TestTools.Core -find Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe
• CMD: "%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe" -latest -prerelease -products * -requires Microsoft.VisualStudio.PackageGroup.TestTools.Core -find Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe

(Note that the instructions above are slightly modified from Microsoft's official ones. In particular, I've included the -prerelease flag to allow Preview and RC installations to be picked up, and the -products * to detect Visual Studio Build Tools installations.)

It only took over two years but finally in 2019, Microsoft has listened and given us a way to find these vital executables! If you have Visual Studio 2017 and/or 2019 installed, the vswhere utility can be queried for the location of MSBuild et al. Since vswhere is guaranteed by Microsoft to be located at %ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe, there is no bootstrapping and no path hardcoding required anymore.

The magic is the -find parameter, added in version 2.6.2. You can determine the version you have installed by running vswhere, or checking its file properties. If you have an older version, you can simply download the latest one and overwrite the existing %ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vswhere.exe.

vswhere.exe is a standalone executable, so you can download and run it from anywhere you have an internet connection. That means your build scripts can check if the environment they're running on is setup correctly, to name one option.

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

On your aspx page define the HTML Button element with the usual suspects: runat, class, title, etc.

If this element is part of a data bound control (i.e.: grid view, etc.) you may want to use CommandName and possibly CommandArgument as attributes. Add your button's content and closing tag.

<button id="cmdAction" 
    runat="server" onserverclick="cmdAction_Click()" 
    class="Button Styles" 
    title="Does something on the server" 
    <!-- for databound controls -->
    CommandName="cmdname"> 
    CommandArgument="args..."
    >
    <!-- content -->
    <span class="ui-icon ..."></span>
    <span class="push">Click Me</span>
</button>

On the code behind page the element would call the handler that would be defined as the element's ID_Click event function.

protected void cmdAction_Click(object sender, EventArgs e)
{
: do something.
}

There are other solutions as in using custom controls, etc. Also note that I am using this live on projects in VS2K8.

Hoping this helps. Enjoy!

Simple but works well for me

FileName = ActiveWorkbook.Name 
If InStr(FileName, ".") > 0 Then 
   FileName = Left(FileName, InStr(FileName, ".") - 1) 
End If

You can use array.filter to return the first item of each distinct value-

var a = [ 1, 5, 1, 6, 4, 5, 2, 5, 4, 3, 1, 2, 6, 6, 3, 3, 2, 4 ];_x000D_
_x000D_
var unique = a.filter(function(itm, i, a) {_x000D_
    return i == a.indexOf(itm);_x000D_
});_x000D_
_x000D_
console.log(unique);

If supporting IE8 and below is primary, don't use the unsupported filter method.

Otherwise,

if (!Array.prototype.filter) {
    Array.prototype.filter = function(fun, scope) {
        var T = this, A = [], i = 0, itm, L = T.length;
        if (typeof fun == 'function') {
            while(i < L) {
                if (i in T) {
                    itm = T[i];
                    if (fun.call(scope, itm, i, T)) A[A.length] = itm;
                }
                ++i;
            }
        }
        return A;
    }
}

You can convert that time in Unix timestamp by using

select UNIX_TIMESTAMP('2013-11-26 01:24:34')

then convert it in the readable format in whatever format you need

select from_unixtime(UNIX_TIMESTAMP('2013-11-26 01:24:34'),"%Y-%m-%d");

use this code in teminal :

python -m pip install --upgrade PAKAGE_NAME #instead of PAKAGE_NAME 

for example i want update pip pakage :

 python -m pip install --upgrade pip

more example :

python -m pip install --upgrade selenium
python -m pip install --upgrade requests
...

One way is to execute the following.

git clone user@git-server:project_name.git -b branch_name /your/folder

Where branch_name is the branch of your choice and "/your/folder" is the destination folder for that branch. It's true that this will bring other branches giving you the opportunity to merge back and forth.

Update

Now, starting with Git 1.7.10, you can now do this

git clone user@git-server:project_name.git -b branch_name --single-branch /your/folder

A char is an integral type. When you write

char ch = 'A';

you're setting the value of ch to whatever number your compiler uses to represent the character 'A'. That's usually the ASCII code for 'A' these days, but that's not required. You're almost certainly using a system that uses ASCII.

Like any numeric type, you can initialize it with an ordinary number:

char ch = 13;

If you want do do arithmetic on a char value, just do it: ch = ch + 1; etc.

However, in order to display the value you have to get around the assumption in the iostreams library that you want to display char values as characters rather than numbers. There are a couple of ways to do that.

std::cout << +ch << '\n';
std::cout << int(ch) << '\n'

In Java 8:

scheduler = Executors.newScheduledThreadPool(1);

//Change here for the hour you want ----------------------------------.at()       
Long midnight=LocalDateTime.now().until(LocalDate.now().plusDays(1).atStartOfDay(), ChronoUnit.MINUTES);
scheduler.scheduleAtFixedRate(this, midnight, 1440, TimeUnit.MINUTES);

I use PyCharm which has great capabilities to compare between folders and files.

Just open the parent folder for both repos and wait until it indexes. Then you can use right click on a folder or file and Compare to... and pick the corresponding folder / file on the other side.

It shows not only what files are different but also their content. Much easier than command line.

if (cursor.getCount() == 0)
  return;

cursor.moveToFirst();

while (!cursor.isAfterLast())
{
  // do something
  cursor.moveToNext();
}

cursor.close();

SQLite doesn't define any particular extension for this, it's your own choice. Personally, I name them with the .sqlite extension, just so there isn't any ambiguity when I'm looking at my files later.

Anonymous types can implement interfaces via a dynamic proxy.

I wrote an extension method on GitHub and a blog post http://wblo.gs/feE to support this scenario.

The method can be used like this:

class Program
{
    static void Main(string[] args)
    {
        var developer = new { Name = "Jason Bowers" };

        PrintDeveloperName(developer.DuckCast<IDeveloper>());

        Console.ReadKey();
    }

    private static void PrintDeveloperName(IDeveloper developer)
    {
        Console.WriteLine(developer.Name);
    }
}

public interface IDeveloper
{
    string Name { get; }
}

Based on the excellent answer by trincot, I wrote a reusable function that accepts a handler to run over each item in an array. The function itself returns a promise that allows you to wait until the loop has finished and the handler function that you pass may also return a promise.

loop(items, handler) : Promise

It took me some time to get it right, but I believe the following code will be usable in a lot of promise-looping situations.

Copy-paste ready code:

// SEE https://stackoverflow.com/a/46295049/286685
const loop = (arr, fn, busy, err, i=0) => {
  const body = (ok,er) => {
    try {const r = fn(arr[i], i, arr); r && r.then ? r.then(ok).catch(er) : ok(r)}
    catch(e) {er(e)}
  }
  const next = (ok,er) => () => loop(arr, fn, ok, er, ++i)
  const run  = (ok,er) => i < arr.length ? new Promise(body).then(next(ok,er)).catch(er) : ok()
  return busy ? run(busy,err) : new Promise(run)
}

Usage

To use it, call it with the array to loop over as the first argument and the handler function as the second. Do not pass parameters for the third, fourth and fifth arguments, they are used internally.

const loop = (arr, fn, busy, err, i=0) => {_x000D_
  const body = (ok,er) => {_x000D_
    try {const r = fn(arr[i], i, arr); r && r.then ? r.then(ok).catch(er) : ok(r)}_x000D_
    catch(e) {er(e)}_x000D_
  }_x000D_
  const next = (ok,er) => () => loop(arr, fn, ok, er, ++i)_x000D_
  const run  = (ok,er) => i < arr.length ? new Promise(body).then(next(ok,er)).catch(er) : ok()_x000D_
  return busy ? run(busy,err) : new Promise(run)_x000D_
}_x000D_
_x000D_
const items = ['one', 'two', 'three']_x000D_
_x000D_
loop(items, item => {_x000D_
  console.info(item)_x000D_
})_x000D_
.then(() => console.info('Done!'))

Advanced use cases

Let's look at the handler function, nested loops and error handling.

handler(current, index, all)

The handler gets passed 3 arguments. The current item, the index of the current item and the complete array being looped over. If the handler function needs to do async work, it can return a promise and the loop function will wait for the promise to resolve before starting the next iteration. You can nest loop invocations and all works as expected.

const loop = (arr, fn, busy, err, i=0) => {_x000D_
  const body = (ok,er) => {_x000D_
    try {const r = fn(arr[i], i, arr); r && r.then ? r.then(ok).catch(er) : ok(r)}_x000D_
    catch(e) {er(e)}_x000D_
  }_x000D_
  const next = (ok,er) => () => loop(arr, fn, ok, er, ++i)_x000D_
  const run  = (ok,er) => i < arr.length ? new Promise(body).then(next(ok,er)).catch(er) : ok()_x000D_
  return busy ? run(busy,err) : new Promise(run)_x000D_
}_x000D_
_x000D_
const tests = [_x000D_
  [],_x000D_
  ['one', 'two'],_x000D_
  ['A', 'B', 'C']_x000D_
]_x000D_
_x000D_
loop(tests, (test, idx, all) => new Promise((testNext, testFailed) => {_x000D_
  console.info('Performing test ' + idx)_x000D_
  return loop(test, (testCase) => {_x000D_
    console.info(testCase)_x000D_
  })_x000D_
  .then(testNext)_x000D_
  .catch(testFailed)_x000D_
}))_x000D_
.then(() => console.info('All tests done'))

Error handling

Many promise-looping examples I looked at break down when an exception occurs. Getting this function to do the right thing was pretty tricky, but as far as I can tell it is working now. Make sure to add a catch handler to any inner loops and invoke the rejection function when it happens. E.g.:

const loop = (arr, fn, busy, err, i=0) => {_x000D_
  const body = (ok,er) => {_x000D_
    try {const r = fn(arr[i], i, arr); r && r.then ? r.then(ok).catch(er) : ok(r)}_x000D_
    catch(e) {er(e)}_x000D_
  }_x000D_
  const next = (ok,er) => () => loop(arr, fn, ok, er, ++i)_x000D_
  const run  = (ok,er) => i < arr.length ? new Promise(body).then(next(ok,er)).catch(er) : ok()_x000D_
  return busy ? run(busy,err) : new Promise(run)_x000D_
}_x000D_
_x000D_
const tests = [_x000D_
  [],_x000D_
  ['one', 'two'],_x000D_
  ['A', 'B', 'C']_x000D_
]_x000D_
_x000D_
loop(tests, (test, idx, all) => new Promise((testNext, testFailed) => {_x000D_
  console.info('Performing test ' + idx)_x000D_
  loop(test, (testCase) => {_x000D_
    if (idx == 2) throw new Error()_x000D_
    console.info(testCase)_x000D_
  })_x000D_
  .then(testNext)_x000D_
  .catch(testFailed)  //  <--- DON'T FORGET!!_x000D_
}))_x000D_
.then(() => console.error('Oops, test should have failed'))_x000D_
.catch(e => console.info('Succesfully caught error: ', e))_x000D_
.then(() => console.info('All tests done'))

UPDATE: NPM package

Since writing this answer, I turned the above code in an NPM package.

for-async

Install

npm install --save for-async

Import

var forAsync = require('for-async');  // Common JS, or
import forAsync from 'for-async';

Usage (async)

var arr = ['some', 'cool', 'array'];
forAsync(arr, function(item, idx){
  return new Promise(function(resolve){
    setTimeout(function(){
      console.info(item, idx);
      // Logs 3 lines: `some 0`, `cool 1`, `array 2`
      resolve(); // <-- signals that this iteration is complete
    }, 25); // delay 25 ms to make async
  })
})

See the package readme for more details.

1. Create a class

public class Test {

 public static void main(String[] args) {
    // TODO Auto-generated method stub
     String s[] = {"app","amm","abb","akk","all"};
     doForAllTabs(s);

 }
 public static void doForAllTabs(String[] tablist){
     for(int i = 0; i<tablist.length;i++){
         System.out.println(tablist[i]);
    }
  }
}

2. Right click on left side of System.out.println(tablist[i]); in Eclipse --> select Toggle Breakpoint

3. Right click on toggle point --> select Breakpoint properties

4. Check the Conditional Check Box --> write tablist[i].equalsIgnoreCase("amm") in text field --> Click on OK

5. Right click on class --> Debug As --> Java Application

While other answers have noted the differences correctly, note that if you are in fact returning a ViewResult only it is better to return the more specific type rather than the base ActionResult type. An obvious exception to this principle is when your method returns multiple types deriving from ActionResult.

For a full discussion of the reasons behind this principle please see the related discussion here: Must ASP.NET MVC Controller Methods Return ActionResult?

This can also happen if you have a naming policy around version, prohibiting the version# you are trying to deploy. In my case I was trying to upload a version (to release repo) 2.0.1 but later found out that our nexus configuration doesn't allow anything other than whole number for releases.

I tried later with version 2 and deployed it successfully.

The error message definitely dosen't help:

Return code is: 400, ReasonPhrase: Repository does not allow updating assets: maven-releases-xxx. -> [Help 1]

A better message could have been version 2.0.1 violates naming policy

The "responsible" answer would be for me to suggest building a ViewModel for the dialog and use two-way databinding on the TextBox so that the ViewModel had some "ResponseText" property or what not. This is easy enough to do but probably overkill.

The pragmatic answer would be to just give your text box an x:Name so that it becomes a member and expose the text as a property in your code behind class like so:

<!-- Incredibly simplified XAML -->
<Window x:Class="MyDialog">
   <StackPanel>
       <TextBlock Text="Enter some text" />
       <TextBox x:Name="ResponseTextBox" />
       <Button Content="OK" Click="OKButton_Click" />
   </StackPanel>
</Window>

Then in your code behind...

partial class MyDialog : Window {

    public MyDialog() {
        InitializeComponent();
    }

    public string ResponseText {
        get { return ResponseTextBox.Text; }
        set { ResponseTextBox.Text = value; }
    }

    private void OKButton_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        DialogResult = true;
    }
}

Then to use it...

var dialog = new MyDialog();
if (dialog.ShowDialog() == true) {
    MessageBox.Show("You said: " + dialog.ResponseText);
}

Interesting question - I don't think there's any Oracle function that does this (almost like a "which" command in Unix), but you can get the resolution order for the name by:

select * from 
(
 select  object_name objname, object_type, 'my object' details, 1 resolveOrder 
  from user_objects
  where object_type not like 'SYNONYM'
 union all
 select synonym_name obj , 'my synonym', table_owner||'.'||table_name, 2 resolveOrder
  from user_synonyms
 union all
 select  synonym_name obj , 'public synonym', table_owner||'.'||table_name, 3 resolveOrder
  from all_synonyms where owner = 'PUBLIC'
)
where objname like upper('&objOfInterest')

XMLHttpRequest is a built-in object in web browsers.

It is not distributed with Node; you have to install it separately,

1. Install it with npm,

   npm install xmlhttprequest
   

2. Now you can require it in your code.

   var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
   var xhr = new XMLHttpRequest();
   

That said, the http module is the built-in tool for making HTTP requests from Node.

Axios is a library for making HTTP requests which is available for Node and browsers that is very popular these days.

I appreciate this question and all the info with it. I have something in mind that's kind of a question and an answer when it comes to String.Index.

I'm trying to see if there is an O(1) way to access a Substring (or Character) inside a String because string.index(startIndex, offsetBy: 1) is O(n) speed if you look at the definition of index function. Of course we can do something like:

let characterArray = Array(string)

then access any position in the characterArray however SPACE complexity of this is n = length of string, O(n) so it's kind of a waste of space.

I was looking at Swift.String documentation in Xcode and there is a frozen public struct called Index. We can initialize is as:

let index = String.Index(encodedOffset: 0)

Then simply access or print any index in our String object as such:

print(string[index])

Note: be careful not to go out of bounds`

This works and that's great but what is the run-time and space complexity of doing it this way? Is it any better?

I had the same problem, but none of the solutions worked for me, because the message The system cannot find the file specified can be misleading in some special cases.

In my case, I use Notepad++ in combination with the registry redirect for notepad.exe. Unfortunately my path to Notepad++ in the registry was wrong.

So in fact the message The system cannot find the file specified was telling me, that it cannot find the application (Notepad++) associated with the file type(*.txt), not the file itself.

As Html.fromHtml deprecated I simply I used this code to get String2 in next line.

textView.setText(fromHtml("String1 <br/> String2"));

.

@SuppressWarnings("deprecation")
    public static Spanned fromHtml(String html){
        Spanned result;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
            result = Html.fromHtml(html,Html.FROM_HTML_MODE_LEGACY);
        } else {
            result = Html.fromHtml(html);
        }
        return result;
    }

You could also accomplish using angular-activity-monitor in a more straight forward way than injecting multiple providers and it uses setInterval() (vs. angular's $interval) to avoid manually triggering a digest loop (which is important to prevent keeping items alive unintentionally).

Ultimately, you just subscribe to a few events that determine when a user is inactive or becoming close. So if you wanted to log out a user after 10 minutes of inactivity, you could use the following snippet:

angular.module('myModule', ['ActivityMonitor']);

MyController.$inject = ['ActivityMonitor'];
function MyController(ActivityMonitor) {
  // how long (in seconds) until user is considered inactive
  ActivityMonitor.options.inactive = 600;

  ActivityMonitor.on('inactive', function() {
    // user is considered inactive, logout etc.
  });

  ActivityMonitor.on('keepAlive', function() {
    // items to keep alive in the background while user is active
  });

  ActivityMonitor.on('warning', function() {
    // alert user when they're nearing inactivity
  });
}

This is working for me on iOS 6.1 and with Bootstrap JS links (i.e dropdown menus etc)

$(document).ready(function(){
    if (("standalone" in window.navigator) && window.navigator.standalone) {
      // For iOS Apps
      $('a').on('click', function(e){
        e.preventDefault();
        var new_location = $(this).attr('href');
        if (new_location != undefined && new_location.substr(0, 1) != '#' && $(this).attr('data-method') == undefined){
          window.location = new_location;
        }
      });
    }
  });

The array declaration should be:

Car[] garage = new Car[100];

You can also just assign directly:

garage[1] = new Car("Blue");

In python 3.2 and later, there is a useful contextmanager for this in the stdlib https://docs.python.org/3/library/tempfile.html#tempfile.TemporaryDirectory

var date = new Date()
console.log(" Date in MS last three digit = "+  date.getMilliseconds())
console.log(" MS = "+ Date.now())

Using this we can get date in milliseconds

Syntax it for Sql server

SELECT MAX(Salary) as 'Salary' from EmployeeDetails
where Salary NOT IN
(
SELECT TOP n-1 (SALARY) from EmployeeDetails ORDER BY Salary Desc
)

To get 2nd highest salary of employee then we need replace “n” with 2 our query like will be this

SELECT MAX(Salary) as 'Salary' from EmployeeDetails
where Salary NOT IN
(
SELECT TOP 1 (SALARY) from EmployeeDetails ORDER BY Salary Desc
)

3rd highest salary of employee

SELECT MAX(Salary) as 'Salary' from EmployeeDetails
where Salary NOT IN
(
SELECT TOP 2 (SALARY) from EmployeeDetails ORDER BY Salary Desc
)

Try with:

#! /bin/bash

i=0
while read line
do
    array[ $i ]="$line"        
    (( i++ ))
done < <(ls -ls)

echo ${array[1]}

In your version, the while runs in a subshell, the environment variables you modify in the loop are not visible outside it.

(Do keep in mind that parsing the output of ls is generally not a good idea at all.)

Your server process has received a SIGPIPE writing to a socket. This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close function).

In a C program you would normally try setting to ignore SIGPIPE signal or setting a dummy signal handler for it. In this case a simple error will be returned when writing to a closed socket. In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.

I tried the solution suggested by LukeP and found that it doesn't support the Authorize attribute. So, I modified it a bit.

public class UserExBusinessInfo
{
    public int BusinessID { get; set; }
    public string Name { get; set; }
}

public class UserExInfo
{
    public IEnumerable<UserExBusinessInfo> BusinessInfo { get; set; }
    public int? CurrentBusinessID { get; set; }
}

public class PrincipalEx : ClaimsPrincipal
{
    private readonly UserExInfo userExInfo;
    public UserExInfo UserExInfo => userExInfo;

    public PrincipalEx(IPrincipal baseModel, UserExInfo userExInfo)
        : base(baseModel)
    {
        this.userExInfo = userExInfo;
    }
}

public class PrincipalExSerializeModel
{
    public UserExInfo UserExInfo { get; set; }
}

public static class IPrincipalHelpers
{
    public static UserExInfo ExInfo(this IPrincipal @this) => (@this as PrincipalEx)?.UserExInfo;
}

                AuthManager.SignOut();
                AuthManager.SignIn(new AuthenticationProperties { IsPersistent = false }, ident);

                user.LastLoginDate = DateTime.UtcNow;
                await UserManager.UpdateAsync(user);

                PrincipalExSerializeModel serializeModel = new PrincipalExSerializeModel();
                serializeModel.UserExInfo = new UserExInfo()
                {
                    BusinessInfo = await
                        db.Businesses
                        .Where(b => user.Id.Equals(b.AspNetUserID))
                        .Select(b => new UserExBusinessInfo { BusinessID = b.BusinessID, Name = b.Name })
                        .ToListAsync()
                };

                JavaScriptSerializer serializer = new JavaScriptSerializer();

                string userData = serializer.Serialize(serializeModel);

                FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
                         1,
                         details.Name,
                         DateTime.Now,
                         DateTime.Now.AddMinutes(15),
                         false,
                         userData);

                string encTicket = FormsAuthentication.Encrypt(authTicket);
                HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
                Response.Cookies.Add(faCookie);

                return RedirectToLocal(returnUrl);
            }
        }
        return View(details);
    }

And finally in Global.asax.cs

    protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
    {
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];

        if (authCookie != null)
        {
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            PrincipalExSerializeModel serializeModel = serializer.Deserialize<PrincipalExSerializeModel>(authTicket.UserData);
            PrincipalEx newUser = new PrincipalEx(HttpContext.Current.User, serializeModel.UserExInfo);
            HttpContext.Current.User = newUser;
        }
    }

Now I can access the data in views and controllers simply by calling

User.ExInfo()

To log out I just call

AuthManager.SignOut();

where AuthManager is

HttpContext.GetOwinContext().Authentication

You should use Enum.TryParse to achive your goal

This is a example:

[Flags]
private enum TestEnum
{
    Value1 = 1,
    Value2 = 2
}

static void Main(string[] args)
{
    var enumName = "Value1";
    TestEnum enumValue;

    if (!TestEnum.TryParse(enumName, out enumValue))
    {
        throw new Exception("Wrong enum value");
    }

    // enumValue contains parsed value
}

For this problem Onpagechange listener is the best one But it will also have one small mistake that is it will not detect the starting time time of 0th position Once you will change the page it will starts to detect the Page selected position...For this problem I fount the easiest solution

1.You have to maintain the selected position value then use it....
2. Case 1: At the starting of the position is always Zero....
Case 2: Suppose if you set the current item means you will set that value into maintain position
3.Then do your action with the use of that maintain in your activity...

Public int maintain=0;
myViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int i, float v, int i2) {
             //Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onPageSelected( int i) {
          // here you will get the position of selected page
            maintain = i;


        }

        @Override
        public void onPageScrollStateChanged(int i) {

        }
    });


updateButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
            data.set(maintain, "Replaced "+maintain);         
            myViewPager.getAdapter().notifyDataSetChanged();
        }
    });

There is a package date_format

dependencies:
    date_format:

code

import 'package:date_format/date_format.dart';

final formattedStr = formatDate(
    yourDateTime, [dd, '.', mm, '.', yy, ' ', HH, ':', nn]);

// output example "29.03.19 07:00"

Pay attention: minutes are nn

link to the package

A variation of the function provided by Paolo Bergantino that works directly on String:

String.prototype.addSlashes = function() 
{ 
   //no need to do (str+'') anymore because 'this' can only be a string
   return this.replace(/[\\"']/g, '\\$&').replace(/\u0000/g, '\\0');
} 

By adding the code above in your library you will be able to do:

var test = "hello single ' double \" and slash \\ yippie";
alert(test.addSlashes());

EDIT:

Following suggestions in the comments, whoever is concerned about conflicts amongst JavaScript libraries can add the following code:

if(!String.prototype.addSlashes)
{
   String.prototype.addSlashes = function()... 
}
else
   alert("Warning: String.addSlashes has already been declared elsewhere.");

You can try running a simple web server based on Twisted

You should be able to utilize the StringUtils class and the countMatches() method.

public static int countMatches(String str, String sub)

Counts how many times the substring appears in the larger String.

Try the following:

int count = StringUtils.countMatches("a.b.c.d", ".");

If you can't use the TextDecoder API because it is not supported on IE:

1. You can use the FastestSmallestTextEncoderDecoder polyfill recommended by the Mozilla Developer Network website;
2. You can use this function also provided at the MDN website:

I found the solution here:

How to properly -filter multiple strings in a PowerShell copy script

You have to use -Include flag for Get-ChildItem

My Example:

$Location = "C:\user\files" 
$result = (Get-ChildItem $Location\* -Include *.png, *.gif, *.jpg)

Dont forget put "*" after path location.

Use the Out-File cmdlet

 Compare-Object ... | Out-File C:\filename.txt

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

Is the $_SESSION['name'] variable an array? If you want to delete a specific key from within an array, you have to refer to that exact key in the unset() call, otherwise you delete the entire array, e.g.

$name = array(0 => 'a', 1 => 'b', 2 => 'c');
unset($name); // deletes the entire array
unset($name[1]); // deletes only the 'b' entry

Another minor problem with your snippet: You're mixing GET query parameters in with a POST form. Is there any reason why you can't do the forms with 'name' being passed in a hidden field? It's best to not mix get and post variables, especially if you use $_REQUEST elsewhere. You can run into all kinds of fun trying to figure out why $_GET['name'] isn't showing up the same as $_POST['name'], because the server's got a differnt EGPCS order set in the 'variables_order' .ini setting.

<form blah blah blah method="post">
  <input type="hidden" name="name" value="<?= htmlspecialchars($list1) ?>" />
  <input type="submit" name="add" value="Add />
</form>

And note the htmlspecialchars() call. If either $list1 or $list2 contain a double quote ("), it'll break your HTML

I simply write it this way

in the AspectType file:

class AspectType {
  //blah blah
}
module.exports = AspectType;

and import it like this:

const AspectType = require('./AspectType');
var aspectType = new AspectType;

In gcc, this isn't supported. In fact, this isn't supported in any existing compiler/linker i'm aware of.

I found this very useful. It is a very simple approach where you create patches that are applied to the new repo. See the linked page for more details.

It only contains three steps (copied from the blog):

# Setup a directory to hold the patches
mkdir <patch-directory>

# Create the patches
git format-patch -o <patch-directory> --root /path/to/copy

# Apply the patches in the new repo using a 3 way merge in case of conflicts
# (merges from the other repo are not turned into patches). 
# The 3way can be omitted.
git am --3way <patch-directory>/*.patch

The only issue I had was that I could not apply all patches at once using

git am --3way <patch-directory>/*.patch

Under Windows I got an InvalidArgument error. So I had to apply all patches one after another.

DID NOT WORK:

I have already had the following dependency in my build.gradle

implementation 'com.android.support:support-v13:26.0.2'

I have tried all of the following,

• Invalidate Caches/Restart
• Sync project with gradle files
• Clean project
• Rebuild project
• gradlew clean

But, none of them worked for me.

SOLUTION:

Finally, I solved it by deleting "/.idea/libraries", and then synced with gradle and built again.

1. Use conditional formatting instead of VBA to highlight errors.

2. Using a VBA loop like the one you posted will take a long time to process

3. the statement If cell.Value = "#N/A" Then will never work. If you insist on using VBA to highlight errors, try this instead.

   Sub ColorCells()

   Dim Data As Range
   Dim cell As Range
   Set currentsheet = ActiveWorkbook.Sheets("Comparison")
   Set Data = currentsheet.Range("A2:AW1048576")
   
   For Each cell In Data
   
   If IsError(cell.Value) Then
      cell.Interior.ColorIndex = 3
   End If
   Next
   
   End Sub
   

4. Be prepared for a long wait, since the procedure loops through 51 million cells

5. There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.

Here is exp.

$date_search_strtotime = strtotime(date("Y-m-d"));
echo 'Now strtotime date : '.$date_search_strtotime;
echo '<br>';
echo 'Now date from strtotime : '.date('Y-m-d',$date_search_strtotime);

An HTML element like div can have more than one classes. Let say div is assigned two styles using addClass method. If style1 has 3 properties like font-size, weight and color, and style2 has 4 properties like font-size, weight, color and background-color, the resultant effective properties set (style), i think, will have 4 properties i.e. union of all style sets. Common properties, in our case, color,font-size, weight, will have one occuerance with latest values. If div is assigned style1 first and style2 second, the common prpoerties will be overwritten by style2 values.

Further, I have written a post at Using JQuery to Apply,Remove and Manage Styles, I hope it will help you

In case anyone is as dopey as me, double check the year of your date. I was converting a date from a text file in YYMMDD format so was creating a date with a year of 0020, not 2020. Obvious error but I spent more time looking at it but not seeing it than I should have!

Create ImageCell2.swift

Step 1

import UIKit

class ImageCell2: UITableViewCell {

    @IBOutlet weak var imgBookLogo: UIImageView!
    @IBOutlet weak var lblTitle: UILabel!
    @IBOutlet weak var lblPublisher: UILabel!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
    }

}

step 2 . According Viewcontroller class

  import UIKit

    class ImageListVC: UIViewController,UITableViewDataSource,UITableViewDelegate {
    @IBOutlet weak var tblMainVC: UITableView!

    var arrBook : [BookItem] = [BookItem]()

    override func viewDidLoad() {
        super.viewDidLoad()
         //Regester Cell
        self.tblMainVC.register(UINib.init(nibName: "ImageCell2", bundle: nil), forCellReuseIdentifier: "ImageCell2")
        // Response Call adn Disply Record
        APIManagerData._APIManagerInstance.getAPIBook { (itemInstance) in
            self.arrBook = itemInstance.arrItem!
            self.tblMainVC.reloadData()
        }
    }
    //MARK: DataSource & delegate
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.arrBook.count
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//    [enter image description here][2]
        let cell  = tableView.dequeueReusableCell(withIdentifier: "ImageCell2") as! ImageCell2
        cell.lblTitle.text = self.arrBook[indexPath.row].title
        cell.lblPublisher.text = self.arrBook[indexPath.row].publisher
        if let authors = self.arrBook[indexPath.row].author {
            for item in authors{
                print(" item \(item)")
            }
        }
        let  url  = self.arrBook[indexPath.row].imageURL
        if url == nil {
            cell.imgBookLogo.kf.setImage(with: URL.init(string: ""), placeholder: UIImage.init(named: "download.jpeg"))
        }
        else{
            cell.imgBookLogo.kf.setImage(with: URL(string: url!)!, placeholder: UIImage.init(named: "download.jpeg"))
        }
        return cell
    }
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 90
    } 

}

Here is the complete set of JS and CSS required for the export table plugin to work perfectly.

                        ]
                    });

Result :-

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

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

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

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

For instance:

Ruby

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

Python

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

C#

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

Lua

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

I was having the same issue, particularly noticeable when my <h2> element wrapped to a second line.

I applied a class to a <div> in the infoWindow, and changed the fonts to a generic system font (in my case, Helvetica) versus an @font-face web font which it had been using. Issue solved.

For future readers:

To select manually the buttons with the trackball use:

myListView.setItemsCanFocus(true);

And to disable the focus on the whole list items:

myListView.setFocusable(false);
myListView.setFocusableInTouchMode(false);
myListView.setClickable(false);

It works fine for me, I can click on buttons with touchscreen and also alows focus an click using keypad

cache:true only works with GET and HEAD request.

You could roll your own solution as you said with something along these lines :

var localCache = {
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url];
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = cachedData;
        if ($.isFunction(callback)) callback(cachedData);
    }
};

Working fiddle here

EDIT: as this post becomes popular, here is an even better answer for those who want to manage timeout cache and you also don't have to bother with all the mess in the $.ajax() as I use $.ajaxPrefilter(). Now just setting {cache: true} is enough to handle the cache correctly :

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        var complete = originalOptions.complete || $.noop,
            url = originalOptions.url;
        //remove jQuery cache as we have our own localCache
        options.cache = false;
        options.beforeSend = function () {
            if (localCache.exist(url)) {
                complete(localCache.get(url));
                return false;
            }
            return true;
        };
        options.complete = function (data, textStatus) {
            localCache.set(url, data, complete);
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true,
            complete: doSomething
        });
    });
});

function doSomething(data) {
    console.log(data);
}

And the fiddle here CAREFUL, not working with $.Deferred

Here is a working but flawed implementation working with deferred:

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        //Here is our identifier for the cache. Maybe have a better, safer ID (it depends on the object string representation here) ?
        // on $.ajax call we could also set an ID in originalOptions
        var id = originalOptions.url+ JSON.stringify(originalOptions.data);
        options.cache = false;
        options.beforeSend = function () {
            if (!localCache.exist(id)) {
                jqXHR.promise().done(function (data, textStatus) {
                    localCache.set(id, data);
                });
            }
            return true;
        };

    }
});

$.ajaxTransport("+*", function (options, originalOptions, jqXHR, headers, completeCallback) {

    //same here, careful because options.url has already been through jQuery processing
    var id = originalOptions.url+ JSON.stringify(originalOptions.data);

    options.cache = false;

    if (localCache.exist(id)) {
        return {
            send: function (headers, completeCallback) {
                completeCallback(200, "OK", localCache.get(id));
            },
            abort: function () {
                /* abort code, nothing needed here I guess... */
            }
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true
        }).done(function (data, status, jq) {
            console.debug({
                data: data,
                status: status,

Fiddle HERE Some issues, our cache ID is dependent of the json2 lib JSON object representation.

Use Console view (F12) or FireBug to view some logs generated by the cache.

In my case it was failing as the IP of my source server was not whitelisted in the target server.

For e.g. I was trying to access https://prodcat.ref.test.co.uk from application running on my source server. On source server find IP by ifconfig

This IP should be whitelisted in the target Server's apache config file. If its not then get it whitelist.

Steps to add a IP for whitelisting (if you control the target server as well) ssh to the apache server sudo su - cd /usr/local/apache/conf/extra (actual directories can be different based on your config)

Find the config file for the target application for e.g. prodcat-443.conf

RewriteCond %{REMOTE_ADDR} <YOUR Server's IP> 
for e.g.
RewriteCond %{REMOTE_ADDR} !^192\.68\.2\.98

Hope this helps someone

I've found an easy way to export query results from SQL Server Management Studio 2005 to Excel.

1) Select menu item Query -> Query Options.

2) Set check box in Results -> Grid -> Include column headers when copying or saving the results.

After that, when you Select All and Copy the query results, you can paste them to Excel, and the column headers will be present.

References are not objects. They don't have storage of their own, they just reference existing objects. For this reason it doesn't make sense to have arrays of references.

If you want a light-weight object that references another object then you can use a pointer. You will only be able to use a struct with a reference member as objects in arrays if you provide explicit initialization for all the reference members for all struct instances. References cannot be default initalized.

Edit: As jia3ep notes, in the standard section on declarations there is an explicit prohibition on arrays of references.

Have you tried setting the painted border false?

JButton button = new JButton();
button.setBackground(Color.red);
button.setOpaque(true);
button.setBorderPainted(false);

It works on my mac :)

Try

apt-get -d install <packages>

It is documented in man apt-get.

Just for clarification; the downloaded packages are located in the apt package cache at

/var/cache/apt/archives

Since the integration of OpenCV is such an effort, we pre-packaged it and published it via JCenter here: https://github.com/quickbirdstudios/opencv-android

Just include this in your module's build.gradle dependencies section

dependencies {
  implementation 'com.quickbirdstudios:opencv:3.4.1'
}

and this in your project's build.gradle repositories section

repositories {
  jcenter()
}

You won't get lint error after gradle import but don't forget to initialize the OpenCV library like this in MainActivity

public class MainActivity extends Activity {
    static {
        if (!OpenCVLoader.initDebug())
            Log.d("ERROR", "Unable to load OpenCV");
        else
            Log.d("SUCCESS", "OpenCV loaded");
    }
...
...

I'm curious as to why nobody has come up with the more elegant callback solution. So instead of using a return type you use a handler passed into the method as an argument. The example below has the two contrasting approaches. I know which of the two is more elegant to me. :-)

public class DiceExample {

    public interface Pair<T1, T2> {
        T1 getLeft();

        T2 getRight();
    }

    private Pair<Integer, Integer> rollDiceWithReturnType() {

        double dice1 = (Math.random() * 6);
        double dice2 = (Math.random() * 6);

        return new Pair<Integer, Integer>() {
            @Override
            public Integer getLeft() {
                return (int) Math.ceil(dice1);
            }

            @Override
            public Integer getRight() {
                return (int) Math.ceil(dice2);
            }
        };
    }

    @FunctionalInterface
    public interface ResultHandler {
        void handleDice(int ceil, int ceil2);
    }

    private void rollDiceWithResultHandler(ResultHandler resultHandler) {
        double dice1 = (Math.random() * 6);
        double dice2 = (Math.random() * 6);

        resultHandler.handleDice((int) Math.ceil(dice1), (int) Math.ceil(dice2));
    }

    public static void main(String[] args) {

        DiceExample object = new DiceExample();


        Pair<Integer, Integer> result = object.rollDiceWithReturnType();
        System.out.println("Dice 1: " + result.getLeft());
        System.out.println("Dice 2: " + result.getRight());

        object.rollDiceWithResultHandler((dice1, dice2) -> {
            System.out.println("Dice 1: " + dice1);
            System.out.println("Dice 2: " + dice2);
        });
    }
}

Getting the Id is pretty straight forward and you've solved that.

Your second question though is a little more involved.

So, this is all prerelease stuff right now, but the common problem you're facing is where you're extending the user with new properties ( or an Items collection in you're question).

Out of the box you'll get a file called IdentityModel under the Models folder (at the time of writing). In there you have a couple of classes; ApplicationUser and ApplicationDbContext. To add your collection of Items you'll want to modify the ApplicationUser class, just like you would if this were a normal class you were using with Entity Framework. In fact, if you take a quick look under the hood you'll find that all the identity related classes (User, Role etc...) are just POCOs now with the appropriate data annotations so they play nice with EF6.

Next, you'll need to make some changes to the AccountController constructor so that it knows to use your DbContext.

public AccountController()
{
    IdentityManager = new AuthenticationIdentityManager(
    new IdentityStore(new ApplicationDbContext()));
}

Now getting the whole user object for your logged in user is a little esoteric to be honest.

    var userWithItems = (ApplicationUser)await IdentityManager.Store.Users
    .FindAsync(User.Identity.GetUserId(), CancellationToken.None);

That line will get the job done and you'll be able to access userWithItems.Items like you want.

HTH

This should give you the current date minus 1 year:

select now() - interval '1 year';

Go to the starting line and type ma (mark "a"). Then go to the last line and enter d'a (delete to mark "a").

That will delete all lines from the current to the marked one (inclusive). It's also compatible with vi as well as vim, on the off chance that your environment is not blessed with the latter.

The main point is this:

col-lg-* col-md-* col-xs-* col-sm define how many columns will there be in these different screen sizes.

Example: if you want there to be two columns in desktop screens and in phone screens you put two col-md-6 and two col-xs-6 classes in your columns.

If you want there to be two columns in desktop screens and only one column in phone screens (ie two rows stacked on top of each other) you put two col-md-6 and two col-xs-12 in your columns and because sum will be 24 they will auto stack on top of each other, or just leave xs style out.

With SSL/https and with CSRF_COOKIE_HTTPONLY = False, I still don't have csrftoken in the cookie, either using the getCookie(name) function proposed in django Doc or the jquery.cookie.js proposed by fivef.

Wtower summary is perfect and I thought it would work after removing CSRF_COOKIE_HTTPONLY from settings.py but it does'nt in https!

Why csrftoken is not visible in document.cookie???

Instead of getting

"django_language=fr; csrftoken=rDrGI5cp98MnooPIsygWIF76vuYTkDIt"

I get only

"django_language=fr"

WHY? Like SSL/https removes X-CSRFToken from headers I thought it was due to the proxy header params of Nginx but apparently not... Any idea?

Unlike django doc Notes, it seems impossible to work with csrf_token in cookies with https. The only way to pass csrftoken is through the DOM by using {% csrf_token %} in html and get it in jQuery by using

var csrftoken = $('input[name="csrfmiddlewaretoken"]').val();

It is then possible to pass it to ajax either by header (xhr.setRequestHeader), either by params.

emacs hello.c -nw

This is to open a hello.c file using Emacs inside the terminal.

You can directly convert to an int using the str::parse::<T>() method.

let my_string = "27".to_string();  // `parse()` works with `&str` and `String`!
let my_int = my_string.parse::<i32>().unwrap();

You can either specify the type to parse to with the turbofish operator (::<>) as shown above or via explicit type annotation:

let my_int: i32 = my_string.parse().unwrap();

As mentioned in the comments, parse() returns a Result. This result will be an Err if the string couldn't be parsed as the type specified (for example, the string "peter" can't be parsed as i32).

Right click folder -> Click Tortoise SVN -> Check for modification

I've quite often seen it used, sometimes as super_t, when the base is a complex template type (boost::iterator_adaptor does this, for example)

You could do this

            return res.status(201).json({
                statusCode: req.statusCode,
                method: req.method,
                message: 'Question has been added'
            });

If x is just a single scalar value, you could try something like this to ensure the correct shape of the array that is being appended/concatenated to the rightmost column of a:

import numpy as np
a = np.array([[1,3,4],[1,2,3],[1,2,1]])
x = 10
b = np.hstack((a,x*np.ones((a.shape[0],1))))

returns b as:

array([[  1.,   3.,   4.,  10.],
       [  1.,   2.,   3.,  10.],
       [  1.,   2.,   1.,  10.]])

robocopy:

Robocopy, or "Robust File Copy", is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is robocopy...

For MSVC you can use the linker.

link.exe /dump /linenumbers /disasm /out:foo.dis foo.dll

foo.pdb needs to be available to get symbols

You don't need to use setAttribute for that - This code works (IE8 also)

<div id="something" >Hello</div>
<script type="text/javascript" >
    (function() {
        document.getElementById("something").onclick = function() { 
            alert('hello'); 
        };
    })();
</script>

ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
attr.getSessionId();

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

Other answers don't take into account the possibility of an entry listed multiple times in an array. This will return a hash where each key is a unique object in the array and each value is an array of indices that corresponds to where the object lives:

a = [1, 2, 3, 1, 2, 3, 4]
=> [1, 2, 3, 1, 2, 3, 4]

indices = a.each_with_index.inject(Hash.new { Array.new }) do |hash, (obj, i)| 
    hash[obj] += [i]
    hash
end
=> { 1 => [0, 3], 2 => [1, 4], 3 => [2, 5], 4 => [6] }

This allows for a quick search for duplicate entries:

indices.select { |k, v| v.size > 1 }
=> { 1 => [0, 3], 2 => [1, 4], 3 => [2, 5] }

None of these attributes are reliable because per the servlet spec (2.4, 2.5 and 3.0), these attributes are overridden if you include/forward a second time (or if someone calls getNamedDispatcher). I think the only reliable way to get the original request URI/query string is to stick a filter at the beginning of your filter chain in web.xml that sets your own custom request attributes based on request.getRequestURI()/getQueryString() before any forwards/includes take place.

http://www.caucho.com/resin-3.0/webapp/faq.xtp contains an excellent summary of how this works (minus the technical note that a second forward/include messes up your ability to use these attributes).

A simple solution is to create a script start.sh that runs Java through nohup and then stores the PID to a file:

nohup java -jar myapplication.jar > log.txt 2> errors.txt < /dev/null &
PID=$!
echo $PID > pid.txt

Then your stop script stop.sh would read the PID from the file and kill the application:

PID=$(cat pid.txt)
kill $PID

Of course I've left out some details, like checking whether the process exists and removing pid.txt if you're done.

You can use Multiline Search and Replace in Visual Studio macro which provides nice GUI for the task.

To make the parent directory as well as all other sub-directories writable, just add -R

chmod -R a+w <directory>

The safest way to load htmlContent in a Web view is to:

1. use base64 encoding (official recommendation)
2. specify UFT-8 for html content type, i.e., "text/html; charset=utf-8" instead of "text/html" (personal advice)

"Base64 encoding" is an official recommendation that has been written again (already present in Javadoc) in the latest 01/2019 bug in Chrominium (present in WebView M72 (72.0.3626.76)):

https://bugs.chromium.org/p/chromium/issues/detail?id=929083

Official statement from Chromium team:

"Recommended fix:
Our team recommends you encode data with Base64. We've provided examples for how to do so:

• API docs: https://developer.android.com/reference/android/webkit/WebView.html#loadData(java.lang.String,%20java.lang.String,%20java.lang.String)
• Video talk: https://youtu.be/HGZYtDZhOEQ?t=598 (jump to time stamp 9:58)

This fix is backwards compatible (it works on earlier WebView versions), and should also be future-proof (you won't hit future compatibility problems with respect to content encoding)."

Code sample:

webView.loadData(
    Base64.encodeToString(
        htmlContent.getBytes(StandardCharsets.UTF_8),
        Base64.DEFAULT), // encode in Base64 encoded 
    "text/html; charset=utf-8", // utf-8 html content (personal recommendation)
    "base64"); // always use Base64 encoded data: NEVER PUT "utf-8" here (using base64 or not): This is wrong!

    public static abstract class LocationResult {

}

Efficient C++ version:

template< typename Iterator >
bool is_palindrome( Iterator first, Iterator last, std::locale const& loc = std::locale("") )
{
    if ( first == last )
        return true;

    for( --last; first < last; ++first, --last )
    {
        while( ! std::isalnum( *first, loc ) && first < last )
            ++first;
        while( ! std::isalnum( *last, loc ) && first < last )
            --last;
        if ( std::tolower( *first, loc ) != std::tolower( *last, loc ) )
            return false;
    }
    return true;
}

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100

5  5 500

The component solution and deep-clone solution have their advantages, but also have issues:

1. Sometimes you want to track changes in abstract data - it doesn't always make sense to build components around that data.

2. Deep-cloning your entire data structure every time you make a change can be very expensive.

I think there's a better way. If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal) {
      // Handle changes here!
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

With this structure, handleChange() will receive the specific list item that changed - from there you can do any handling you like.

I have also documented a more complex scenario here, in case you are adding/removing items to your list (rather than only manipulating the items already there).

Looking at PDO :Predefined Constants there is no PDO::PARAM_ARRAY which you would need as is listed on PDOStatement->bindParam

bool PDOStatement::bindParam ( mixed $parameter , mixed &$variable [, int $data_type [, int $length [, mixed $driver_options ]]] )

So I don't think it is achievable.

getElementsByClassName() returns HTMLCollection so you could try this

var button = document.getElementsByClassName("navButton")[0];

Edit

var buttons = document.getElementsByClassName("navButton");
for(i=0;buttons.length;i++){
   buttons[i].onmouseover = function(){
     this.className += ' active' //add class
     this.setAttribute("src", "images/arrows/top_o.png");
   }
}

It depends on how and when you want to redirect the user to another page.

If you want to instantly redirect a user to another page without him seeing anything of a site in between, you should use the PHP header redirect method.

If you have a Javascript and some action of the user has to result in him entering another page, that is when you should use window.location.

The meta tag refresh is often used on download sites whenever you see these "Your download should start automatically" messages. You can let the user load a page, wait for a certain amount of time, then redirect him (e.g. to a to-be-downloaded file) without Javascript.

with slice():

var a = [1,2,3,4];
var lastEl = a.slice(-1)[0]; // 4
// a is still [1,2,3,4]

with pop();

var a = [1,2,3,4];
var lastEl = a.pop(); // 4
// a is now [1,2,3]

see https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array for more information

As some guys already mentioned here the problem is with the exception swallowing in case you just call e.printStackTrace() in the catch block. It won't stop the thread execution and will continue after the try block as in normal condition.

Instead of that you need either try to recover from the exception (in case it is recoverable), or to throw RuntimeException, or to bubble the exception to the caller in order to avoid silent crashes (for example, due to improper logger configuration).

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

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

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

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

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

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

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

You have to return JSON error object yourself after setting the StatusCode, like so ...

if (BadRequest)
{
    Dictionary<string, object> error = new Dictionary<string, object>();
    error.Add("ErrorCode", -1);
    error.Add("ErrorMessage", "Something really bad happened");
    return Json(error);
}

Another way is to have a JsonErrorModel and populate it

public class JsonErrorModel
{
    public int ErrorCode { get; set;}

    public string ErrorMessage { get; set; }
}

public ActionResult SomeMethod()
{

    if (BadRequest)
    {
        var error = new JsonErrorModel
        {
            ErrorCode = -1,
            ErrorMessage = "Something really bad happened"
        };

        return Json(error);
    }

   //Return valid response
}

Take a look at the answer here as well

You build the object before encoding it to a JSON string:

import json

data = {}
data['key'] = 'value'
json_data = json.dumps(data)

JSON is a serialization format, textual data representing a structure. It is not, itself, that structure.

{{ HTML::style('yourcss.css') }}
{{ HTML::script('yourjs.js') }}

You are iterating through an undefined value, ie, com property of the Array's object, you should iterate through the array itself:

$.each(obj, function(key,value) {
   // here `value` refers to the objects 
});

Also note that jQuery intelligently tries to parse the sent JSON, probably you don't need to parse the response. If you are using $.ajax(), you can set the dataType to json which tells jQuery parse the JSON for you.

If it still doesn't work, check the browser's console for troubleshooting.

If you have two buttons and have the same id call to your button click events like this:

Button btn1;
Button btn2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn1= (Button)findViewById(R.id.button1);

    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent(MainActivity.this,target.class);
            startActivity(intent);
        }
    });

    btn2=(Button) findViewById(R.id.button1);//Have same id call previous button---> button1

    btn2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

When you clicked button1, button2 will work and you cannot open your second activity.

Your compiler is right. You can't use the growthRate variable you declared in main as a function.

Maybe you should pick different names for your variables so they don't override function names?

If you need to concatenate paths with quotes, you can use = to replace quotes in a variable. This does not require you to know if the path already contains quotes or not. If there are no quotes, nothing is changed.

@echo off
rem Paths to combine
set DIRECTORY="C:\Directory with spaces"
set FILENAME="sub directory\filename.txt"

rem Combine two paths
set COMBINED="%DIRECTORY:"=%\%FILENAME:"=%"
echo %COMBINED%

rem This is just to illustrate how the = operator works
set DIR_WITHOUT_SPACES=%DIRECTORY:"=%
echo %DIR_WITHOUT_SPACES%

I know it's an old thread but this is something that I'm using and I thought it might help.

It works in python 2.7 and python 3< .

def is_float(num):
    """
    Checks whether a number is float or integer

    Args:
        num(float or int): The number to check

    Returns:
        True if the number is float
    """
    return not (float(num)).is_integer()


class TestIsFloat(unittest.TestCase):
    def test_float(self):
        self.assertTrue(is_float(2.2))

    def test_int(self):
        self.assertFalse(is_float(2))

I would say history has spoken and those who argued in favour of using 0 (zero) were wrong (including Bjarne Stroustrup). The arguments in favour of 0 were mostly aesthetics and "personal preference".

After the creation of C++11, with its new nullptr type, some compilers have started complaining (with default parameters) about passing 0 to functions with pointer arguments, because 0 is not a pointer.

If the code had been written using NULL, a simple search and replace could have been performed through the codebase to make it nullptr instead. If you are stuck with code written using the choice of 0 as a pointer it is far more tedious to update it.

And if you have to write new code right now to the C++03 standard (and can't use nullptr), you really should just use NULL. It'll make it much easier for you to update in the future.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

Delegates are the way to go.

As seen with other answers using views might get outdated. Who knows tomorrow there might be another wrapper and may need to use cell superview]superview]superview]superview]. And if you use tags you would end up with n number of if else conditions to identify the cell. To avoid all of that set up delegates. (By doing so you will be creating a re usable cell class. You can use the same cell class as a base class and all you have to do is implement the delegate methods.)

First we need a interface (protocol) which will be used by cell to communicate(delegate) button clicks. (You can create a separate .h file for protocol and include in both table view controller and custom cell classes OR just add it in custom cell class which will anyway get included in table view controller)

@protocol CellDelegate <NSObject>
- (void)didClickOnCellAtIndex:(NSInteger)cellIndex withData:(id)data;
@end

Include this protocol in custom cell and table view controller. And make sure table view controller confirms to this protocol.

In custom cell create two properties :

@property (weak, nonatomic) id<CellDelegate>delegate;
@property (assign, nonatomic) NSInteger cellIndex;

In UIButton IBAction delegate click : (Same can be done for any action in custom cell class which needs to be delegated back to view controller)

- (IBAction)buttonClicked:(UIButton *)sender {
    if (self.delegate && [self.delegate respondsToSelector:@selector(didClickOnCellAtIndex:withData:)]) {
        [self.delegate didClickOnCellAtIndex:_cellIndex withData:@"any other cell data/property"];
    }
}

In table view controller cellForRowAtIndexPath after dequeing the cell, set the above properties.

cell.delegate = self;
cell.cellIndex = indexPath.row; // Set indexpath if its a grouped table.

And implement the delegate in table view controller:

- (void)didClickOnCellAtIndex:(NSInteger)cellIndex withData:(id)data
{
    // Do additional actions as required.
    NSLog(@"Cell at Index: %d clicked.\n Data received : %@", cellIndex, data);
}

This would be the ideal approach to get custom cell button actions in table view controller.

input[type="checkbox"] {
 /* your style */
}

But this will only work for browsers except IE7 and below, for those you will have to use a class.

s1.Split(';').Select(s => Convert.ToInt32(s)).ToArray();

Untested and off the top of my head...testing now for correct syntax.

Tested and everything looks good.

Here is an approach using str.slice(0, -n). Where n is the number of characters you want to truncate.

var str = 1437203995000;_x000D_
str = str.toString();_x000D_
console.log("Original data: ",str);_x000D_
str = str.slice(0, -3);_x000D_
str = parseInt(str);_x000D_
console.log("After truncate: ",str);

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

Since you are using JSON.NET, personally I would go with serialization so that you can have Intellisense support for your object. You'll need a class that represents your JSON structure. You can build this by hand, or you can use something like json2csharp to generate it for you:

e.g.

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

Then, you can simply call JsonConvert's methods to deserialize the JSON into an object:

RootObject instance = JsonConvert.Deserialize<RootObject>(json);

Then you have Intellisense:

var firstName = instance.People[0].FirstName;
var lastName = instance.People[0].LastName;

Binary tree

Binary tree can be anything which has 2 child and 1 parent. It can be implemented as linked list or array, or with your custom API. Once you start to add more specific rules into it, it becomes more specialized tree. Most common known implementation is that, add smaller nodes on left and larger ones on right.

For example, a labeled binary tree of size 9 and height 3, with a root node whose value is 2. Tree is unbalanced and not sorted. https://en.wikipedia.org/wiki/Binary_tree

For example, in the tree on the left, A has the 6 children {B,C,D,E,F,G}. It can be converted into the binary tree on the right.

Binary Search

Binary Search is technique/algorithm which is used to find specific item on node chain. Binary search works on sorted arrays.

Binary search compares the target value to the middle element of the array; if they are unequal, the half in which the target cannot lie is eliminated and the search continues on the remaining half until it is successful or the remaining half is empty. https://en.wikipedia.org/wiki/Binary_search_algorithm

A tree representing binary search. The array being searched here is [20, 30, 40, 50, 90, 100], and the target value is 40.

Binary search tree

This is one of the implementations of binary tree. This is specialized for searching.

Binary search tree and B-tree data structures are based on binary search.

Binary search trees (BST), sometimes called ordered or sorted binary trees, are a particular type of container: data structures that store "items" (such as numbers, names etc.) in memory. https://en.wikipedia.org/wiki/Binary_search_tree

A binary search tree of size 9 and depth 3, with 8 at the root. The leaves are not drawn.

And finally great schema for performance comparison of well-known data-structures and algorithms applied:

Image taken from Algorithms (4th Edition)

count_smiths = (df['LastName'] == 'Smith').sum()

Python lists are mutable objects and here:

plot_data = [[]] * len(positions) 

you are repeating the same list len(positions) times.

>>> plot_data = [[]] * 3
>>> plot_data
[[], [], []]
>>> plot_data[0].append(1)
>>> plot_data
[[1], [1], [1]]
>>> 

Each list in your list is a reference to the same object. You modify one, you see the modification in all of them.

If you want different lists, you can do this way:

plot_data = [[] for _ in positions]

for example:

>>> pd = [[] for _ in range(3)]
>>> pd
[[], [], []]
>>> pd[0].append(1)
>>> pd
[[1], [], []]

I was looking for the TOTAL size of the column and hit this article, my solution is based off of MarcE's.

The built-in functions work well with Pandas Dataframes.

You could store this into a temporary table.

So instead of doing the CTE/sub query you would use a temp table.

The issue may happen while fetching dependencies from a remote repository. In my case, the repository did not need any authentication and it has been resolved by removing the servers section in the settings.xml file:

      <username>SomeUN</username>
      <password>SomePW</password>
    </server>

ps: I guess your target is mvn clean install instead of maven install clean

adding

You're asking for a comparison between a procedural language and a functional language so I feel your question can be answered here: What is the difference between procedural programming and functional programming?

As to why MS created F# the answer is simply: Creating a functional language with access to the .Net library simply expanded their market base. And seeing how the syntax is nearly identical to OCaml, it really didn't require much effort on their part.

In my case, where the timezones are not available on the server, this works great:

SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`

Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!

Arrays.

Stack:

var stack = [];

//put value on top of stack
stack.push(1);

//remove value from top of stack
var value = stack.pop();

Queue:

var queue = [];

//put value on end of queue
queue.push(1);

//Take first value from queue
var value = queue.shift();

This is worked for me

If your having .so file in armeabi then mention inside ndk that folder alone.

If you're looking to put line breaks into the tooltip that appears on mouseover, there's no reliable crossbrowser way to do that. You'd have to fall back to one of the many Javascript tooltip code samples

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

Recently we had a similar problem and had to solve it in a different way. We had to merge two branches up to two commits, which were not the heads of either branches:

branch A: A1 -> A2 -> A3 -> A4
branch B: B1 -> B2 -> B3 -> B4
branch C: C1 -> A2 -> B3 -> C2

For example, we had to merge branch A up to A2 and branch B up to B3. But branch C had cherry-picks from A and B. When using the SHA of A2 and B3 it looked like there was confusion because of the local branch C which had the same SHA.

To avoid any kind of ambiguity we removed branch C locally, and then created a branch AA starting from commit A2:

git co A
git co SHA-of-A2
git co -b AA

Then we created a branch BB from commit B3:

git co B
git co SHA-of-B3
git co -b BB

At that point we merged the two branches AA and BB. By removing branch C and then referencing the branches instead of the commits it worked.

It's not clear to me how much of this was superstition or what actually made it work, but this "long approach" may be helpful.

Add a border to the regular item, the same color as the background, so that it cannot be seen. That way the item has a border: 1px whether it is being hovered or not.

You can also use the following alternative realpath.

Create a file called path.php

Put the following code inside by specifying the name of the created file.

<?php 
    echo realpath('path.php'); 
?>

A php file that you can move to all your folders to always have the absolute path from where the executed file is located.

I was able to get this to work...

SELECT CAST('<![CDATA[' + LargeTextColumn + ']]>' AS XML) FROM TableName;

jQuery takes care of this for you. The first argument to your .each() callback function is the index of the current iteration of the loop. The second being the current matched DOM element So:

$('#list option').each(function(index, element){
  alert("Iteration: " + index)
});

dummyElem.focus() where dummyElem is a hidden object (e.g. has negative zIndex)?

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

If you don't care too much about performance and want to use the straightforward way, you can use either DIV or IDIV.

DIV or IDIV takes only one operand where it divides a certain register with this operand, the operand can be register or memory location only.

When operand is a byte: AL = AL / operand, AH = remainder (modulus).

Ex:

MOV AL,31h ; Al = 31h

DIV BL ; Al (quotient)= 08h, Ah(remainder)= 01h

when operand is a word: AX = (AX) / operand, DX = remainder (modulus).

Ex:

MOV AX,9031h ; Ax = 9031h

DIV BX ; Ax=1808h & Dx(remainder)= 01h

Not sure why but none of the above solution work for me. So sharing what worked:

public void readXLS(string FilePath)
{
    FileInfo existingFile = new FileInfo(FilePath);
    using (ExcelPackage package = new ExcelPackage(existingFile))
    {
        //get the first worksheet in the workbook
        ExcelWorksheet worksheet = package.Workbook.Worksheets[1];
        int colCount = worksheet.Dimension.End.Column;  //get Column Count
        int rowCount = worksheet.Dimension.End.Row;     //get row count
        for (int row = 1; row <= rowCount; row++)
        {
            for (int col = 1; col <= colCount; col++)
            {
                Console.WriteLine(" Row:" + row + " column:" + col + " Value:" + worksheet.Cells[row, col].Value?.ToString().Trim());
            }
        }
    }
}

I believe this is what you were looking for:

class Expression {
    protected $expression;
    protected $result;

    public function __construct($expression) {
        $this->expression = $expression;
    }

    public function evaluate() {
        $this->result = eval("return ".$this->expression.";");
        return $this;
    }

    public function getResult() {
        return $this->result;
    }
}

class NegativeFinder {
    protected $expressionObj;

    public function __construct(Expression $expressionObj) {
        $this->expressionObj = $expressionObj;
    }

    public function isItNegative() {
        $result = $this->expressionObj->evaluate()->getResult();

        if($this->hasMinusSign($result)) {
            return true;
        } else {
            return false;
        }
    }

    protected function hasMinusSign($value) {
        return (substr(strval($value), 0, 1) == "-");
    }
}

Usage:

$soldPrice = 1;
$boughtPrice = 2;
$negativeFinderObj = new NegativeFinder(new Expression("$soldPrice - $boughtPrice"));

echo ($negativeFinderObj->isItNegative()) ? "It is negative!" : "It is not negative :(";

Do however note that eval is a dangerous function, therefore use it only if you really, really need to find out if a number is negative.

Use this:

boolean success = EmailIntentBuilder.from(activity)
        .to("[email protected]")
        .cc("[email protected]")
        .subject("Error report")
        .body(buildErrorReport())
        .start();

use build gradle :

compile 'de.cketti.mailto:email-intent-builder:1.0.0'

select project to delete->settings->buttom click delete button->enter name of the repositories

According to your requirement

just show me a basic example of using setTimeout to loop something

we have following example which can help you

var itr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];_x000D_
var  interval = 1000; //one second_x000D_
itr.forEach((itr, index) => {_x000D_
_x000D_
  setTimeout(() => {_x000D_
    console.log(itr)_x000D_
  }, index * interval)_x000D_
})

Or by using DBIs sqlRownamesToColumn

library(DBI)
sqlRownamesToColumn(df)

Indeed, you can leave it empty (W3 validator doesn't complain).

Taking the idea one step further: leave out the ="". The advantage of this is that the link isn't treated as an anchor to the current page.

<a href>sth</a>

You want to execute code where the id is not (1 or 2 or 3), but the OR operator does not distribute over id. The only way to say what you want is to say

the id is not 1, and the id is not 2, and the id is not 3.

which translates to

if (id !== 1 && id !== 2 && id !== 3)

or alternatively for something more pythonesque:

if (!(id in [,1,2,3]))

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

Most likely both tables have a column with the same name. Alias each table, and call each column with the table alias.

The quick answer is: Windows Presentation Foundation (WPF) is basically a way of displaying user interface. (see this)

Windows Communication Foundation (WCF) is a framework for creating service oriented applications. (see this)

As for which one you should use, it depends on your requirement. Usually an application written in WPF, ASP.NET..etc called the WCF service to do some processing at the server-side and the service returns the result to the application that called it.

if this is what you want .

The difference is that you can't have a reference to an immutable collection which allows changes. Unmodifiable collections are unmodifiable through that reference, but some other object may point to the same data through which it can be changed.

e.g.

List<String> strings = new ArrayList<String>();
List<String> unmodifiable = Collections.unmodifiableList(strings);
unmodifiable.add("New string"); // will fail at runtime
strings.add("Aha!"); // will succeed
System.out.println(unmodifiable);

Declaration-wise:

New-style classes inherit from object, or from another new-style class.

class NewStyleClass(object):
    pass

class AnotherNewStyleClass(NewStyleClass):
    pass

Old-style classes don't.

class OldStyleClass():
    pass

Python 3 Note:

Python 3 doesn't support old style classes, so either form noted above results in a new-style class.

public String formatStr(float val) {
 return String.format(Locale.CANADA, "%,.2f", val);
}

formatStr(2524.2) // 2,254.20

No, it's unsafe.

Despite the best efforts of the Hibernate team, you simply cannot rely on automatic updates in production. Write your own patches, review them with DBA, test them, then apply them manually.

Theoretically, if hbm2ddl update worked in development, it should work in production too. But in reality, it's not always the case.

Even if it worked OK, it may be sub-optimal. DBAs are paid that much for a reason.

I had a similar problem and solved it by focusing on the dialog after open:

var $dialog = $("#pnlFiltros")
    .dialog({
        autoOpen: false,
        hide: "puff",                   
        width: dWidth,
        height: 'auto',
        draggable: true,
        resizable: true,
        closeOnScape : true,
        position: [x,y]                    
    });
$dialog.dialog('open');
$("#pnlFiltros").focus(); //focus on the div being dialogued (is that a word?)

But in my case the first element is an anchor, so I don't know if in your case that will leave the datepicker opened.

EDIT: only works on IE

Well in general:

List<String> names = new ArrayList<String>();
names.add("john");
names.add("ann");

String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
    namesArr[i] = names.get(i);  
}

Or better yet, using built in:

List<String> names = new ArrayList<String>();
String[] namesArr = names.toArray(new String[names.size()]);

As mentioned in comments, this is a scoping issue. Specifically, $con is not in scope within your getPosts function.

You should pass your connection object in as a dependency, eg

function getPosts(mysqli $con) {
    // etc

I would also highly recommend halting execution if your connection fails or if errors occur. Something like this should suffice

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // throw exceptions
$con=mysqli_connect("localhost","xxxx","xxxx","xxxxx");

getPosts($con);

try this:

struct Pos{
    int x;
    int y;

    inline Pos& operator=(const Pos& other){
        x=other.x;
        y=other.y;
        return *this;
    }

    inline Pos operator+(const Pos& other) const {
        Pos res {x+other.x,y+other.y};
        return res;
    }

    const inline bool operator==(const Pos& other) const {
        return (x==other.x and y == other.y);
    }
 };  

You only need to exclude UserDetailsServiceAutoConfiguration.

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.UserDetailsServiceAutoConfiguration
