I think that the problem is that you put #ifdef instead of #ifndef at the top of your header.h file.

Number of blocks:
malloc() assigns single block of requested memory,
calloc() assigns multiple blocks of the requested memory

Initialization:
malloc() - doesn't clear and initialize the allocated memory.
calloc() - initializes the allocated memory by zero.

Speed:
malloc() is fast.
calloc() is slower than malloc().

Arguments & Syntax:
malloc() takes 1 argument:

1. bytes

   • The number of bytes to be allocated

calloc() takes 2 arguments:

1. length

   • the number of blocks of memory to be allocated

2. bytes

   • the number of bytes to be allocated at each block of memory

void *malloc(size_t bytes);         
void *calloc(size_t length, size_t bytes);      

Manner of memory Allocation:
The malloc function assigns memory of the desired 'size' from the available heap.
The calloc function assigns memory that is the size of what’s equal to ‘num *size’.

Meaning on name:
The name malloc means "memory allocation".
The name calloc means "contiguous allocation".

From what you've told us it does appear to be a false positive in valgrind. The new syntax with () should value-initialize the object, assuming it is POD.

Is it possible that some subpart of your struct isn't actually POD and that's preventing the expected initialization? Are you able to simplify your code into a postable example that still flags the valgrind error?

Alternately perhaps your compiler doesn't actually value-initialize POD structures.

In any case probably the simplest solution is to write constructor(s) as needed for the struct/subparts.

Works finde for me:

$dom = new \DOMDocument;
$dom->loadHTML(utf8_decode($html));
...
return  utf8_encode( $dom->saveHTML());

Tried to use the solution proposed by Misko, but in my situation, some attributes, which needed to be merged into my template html, were themselves directives.

Unfortunately, not all of the directives referenced by the resulting template did work correctly. I did not have enough time to dive into angular code and find out the root cause, but found a workaround, which could potentially be helpful.

The solution was to move the code, which creates the template html, from compile to a template function. Example based on code from above:

    angular.module('formComponents', [])
  .directive('formInput', function() {
    return {
        restrict: 'E',
        template: function(element, attrs) {
           var type = attrs.type || 'text';
            var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
            var htmlText = '<div class="control-group">' +
                '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                    '<div class="controls">' +
                    '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                    '</div>' +
                '</div>';
             return htmlText;
        }
        compile: function(element, attrs)
        {
           //do whatever else is necessary
        }
    }
})

New versions of application servers removed the ability of binding to your entire network interface and limited it just to the local interface (localhost). The reason being was for security. From what I know, Tomcat and JBoss implement the same security measures.

If you want to bind it to another IP you can explicitly set it in your connector string:

• Tomcat: address="192.168.1.100"
• JBoss: you pass in a -b 192.168.1.100 as a command line.

Just remember that binding 0.0.0.0 allows anyone access to your box to access that server. It will bind to all addresses. If that is what you want, then use 0.0.0.0, if it isn't then specify the address you would like to explicitly bind instead.

Just make sure you understand the consequences binding to all addresses (0.0.0.0)

There is an easier way than the one written by CommonsWare. Just create a drawable resource that specifies the way the EditText will be drawn:

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" 
    android:padding="10dp">

    <solid android:color="#FFFFFF" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

Then, just reference this drawable in your layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:padding="5dip"
        android:background="@drawable/rounded_edittext" />
</LinearLayout>

You will get something like:

Edit

Based on Mark's comment, I want to add the way you can create different states for your EditText:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_states.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item 
        android:state_pressed="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_focused="true" 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_focused" />
    <item 
        android:state_enabled="true"
        android:drawable="@drawable/rounded_edittext" />
</selector>

These are the states:

<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext_focused.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">

    <solid android:color="#FFFFFF"/>
    <stroke android:width="2dp" android:color="#FF0000" />
    <corners
        android:bottomRightRadius="15dp"
        android:bottomLeftRadius="15dp"
        android:topLeftRadius="15dp"
        android:topRightRadius="15dp" />
</shape>

And... now, the EditText should look like:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <EditText  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="@string/hello"
        android:background="@drawable/rounded_edittext_states"
        android:padding="5dip" />
</LinearLayout>

For those that like functional programming:

somelist[:] = filter(lambda tup: not determine(tup), somelist)

or

from itertools import ifilterfalse
somelist[:] = list(ifilterfalse(determine, somelist))

Here's one way. You have to get the individual components from the date object (day, month & year) and then build and format the string however you wish.

n =  new Date();_x000D_
y = n.getFullYear();_x000D_
m = n.getMonth() + 1;_x000D_
d = n.getDate();_x000D_
document.getElementById("date").innerHTML = m + "/" + d + "/" + y;

<p id="date"></p>

If your application is launched with npm start, you can simply use:

process.env.npm_package_version

See package.json vars for more details.

Try following steps:

1. Type ipconfig (or ifconfig on Linux) at command prompt. This will give you the IP address of your own machine. For example, your machine's IP address is 192.168.1.6. So your broadcast IP address is 192.168.1.255.
2. Ping your broadcast IP address ping 192.168.1.255 (may require -b on Linux)
3. Now type arp -a. You will get the list of all IP addresses on your segment.

It took me quite a while to figure out, how to not get a false when using openssl_decrypt() and get encrypt and decrypt working.

    // cryptographic key of a binary string 16 bytes long (because AES-128 has a key size of 16 bytes)
    $encryption_key = '58adf8c78efef9570c447295008e2e6e'; // example
    $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc'));
    $encrypted = openssl_encrypt($plaintext, 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, $iv);
    $encrypted = $encrypted . ':' . base64_encode($iv);

    // decrypt to get again $plaintext
    $parts = explode(':', $encrypted);
    $decrypted = openssl_decrypt($parts[0], 'aes-256-cbc', $encryption_key, OPENSSL_RAW_DATA, base64_decode($parts[1])); 

If you want to pass the encrypted string via a URL, you need to urlencode the string:

    $encrypted = urlencode($encrypted);

To better understand what is going on, read:

• http://blog.turret.io/the-missing-php-aes-encryption-example/
• http://thefsb.tumblr.com/post/110749271235/using-opensslendecrypt-in-php-

To generate 16 bytes long keys you can use:

    $bytes = openssl_random_pseudo_bytes(16);
    $hex = bin2hex($bytes);

To see error messages of openssl you can use: echo openssl_error_string();

Hope that helps.

There is a fs.readFileSync( path, options ) method, which is synchronous.

There are 3 location providers in Android.

They are:

gps –> (GPS, AGPS): Name of the GPS location provider. This provider determines location using satellites. Depending on conditions, this provider may take a while to return a location fix. Requires the permission android.permission.ACCESS_FINE_LOCATION.

network –> (AGPS, CellID, WiFi MACID): Name of the network location provider. This provider determines location based on availability of cell tower and WiFi access points. Results are retrieved by means of a network lookup. Requires either of the permissions android.permission.ACCESS_COARSE_LOCATION or android.permission.ACCESS_FINE_LOCATION.

passive –> (CellID, WiFi MACID): A special location provider for receiving locations without actually initiating a location fix. This provider can be used to passively receive location updates when other applications or services request them without actually requesting the locations yourself. This provider will return locations generated by other providers. Requires the permission android.permission.ACCESS_FINE_LOCATION, although if the GPS is not enabled this provider might only return coarse fixes. This is what Android calls these location providers, however, the underlying technologies to make this stuff work is mapped to the specific set of hardware and telco provided capabilities (network service).

The best way is to use the “network” or “passive” provider first, and then fallback on “gps”, and depending on the task, switch between providers. This covers all cases, and provides a lowest common denominator service (in the worst case) and great service (in the best case).

-----------------------Update-----------------------

Now Android have Fused location provider

The Fused Location Provider intelligently manages the underlying location technology and gives you the best location according to your needs. It simplifies ways for apps to get the user’s current location with improved accuracy and lower power usage

Fused location provider provide three ways to fetch location

1. Last Location: Use when you want to know current location once.
2. Request Location using Listener: Use when application is on screen / frontend and require continues location.
3. Request Location using Pending Intent: Use when application in background and require continues location.

This should do the trick:

public static Bitmap getBitmapFromURL(String src) {
    try {
        URL url = new URL(src);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
} // Author: silentnuke

Don't forget to add the internet permission in your manifest.

Possible solution

1. In Notepad++ , click search menu, the click Find
2. in FIND WHAT : enter this ==> cat|town
3. Select REGULAR EXPRESSION radiobutton
4. click FIND IN CURRENT DOCUMENT

Screenshot

Strictly,

other = s if s is not None else "default value"

Otherwise, s = False will become "default value", which may not be what was intended.

If you want to make this shorter, try:

def notNone(s,d):
    if s is None:
        return d
    else:
        return s

other = notNone(s, "default value")

I second NLog too because it works with unmanaged code too. I suppose it could be possibe to use log4net and log4cxx together, but NLog handles both managed and unmanaged code out of the box.

I also looked at Common.Logging, a facade that makes abstraction of the logging api, it supports log4net, NLog and Entreprise Library. I don't think i'll use it, but i like how they use lambdas to improve performance when logging is disabled (a feature shared with NLog and probably others).

The documentation of the file module says

If state=file, the file will NOT be created if it does not exist, see the copy or template module if you want that behavior.

So we use the copy module, using force=no to create a new empty file only when the file does not yet exist (if the file exists, its content is preserved).

- name: ensure file exists
  copy:
    content: ""
    dest: /etc/nologin
    force: no
    group: sys
    owner: root
    mode: 0555

This is a declarative and elegant solution.

The default execution policy, "Restricted", prevents all scripts from running, including scripts that you write on the local computer.

The execution policy is saved in the registry, so you need to change it only once on each computer.

To change the execution policy, use the following procedure:

1. Start Windows PowerShell with the "Run as administrator" option.

2. At the command prompt, type:

   Set-ExecutionPolicy AllSigned

   -or-

   Set-ExecutionPolicy RemoteSigned

The change is effective immediately.

To run a script, type the full name and the full path to the script file.

For example, to run the Get-ServiceLog.ps1 script in the C:\Scripts directory, type:

C:\Scripts\Get-ServiceLog.ps1

And to the Python file, you have two points. Try to add your Python folder to your PATH and the extension .py.

To PATHEXT from go properties of computer. Then click on advanced system protection. Then environment variable. Here you will find the two points.

I generated the following using python and works with the re module. The look-ahead assertions ensure that the correct number of dots or colons appear in the address. It does not support IPv4 in IPv6 notation.

pattern = '^(?=\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$)(?:(?:25[0-5]|[12][0-4][0-9]|1[5-9][0-9]|[1-9]?[0-9])\.?){4}$|(?=^(?:[0-9a-f]{0,4}:){2,7}[0-9a-f]{0,4}$)(?![^:]*::.+::[^:]*$)(?:(?=.*::.*)|(?=\w+:\w+:\w+:\w+:\w+:\w+:\w+:\w+))(?:(?:^|:)(?:[0-9a-f]{4}|[1-9a-f][0-9a-f]{0,3})){0,8}(?:::(?:[0-9a-f]{1,4}(?:$|:)){0,6})?$'
result = re.match(pattern, ip)
if result: result.group(0)

Well, basically what I found is that you can declare the array, but when you set it vba shows you an error.

So I put an special sub to declare global variables and arrays, something like:

Global example(10) As Variant

Sub set_values()

example(1) = 1
example(2) = 1
example(3) = 1
example(4) = 1
example(5) = 1
example(6) = 1
example(7) = 1
example(8) = 1
example(9) = 1
example(10) = 1

End Sub

And whenever I want to use the array, I call the sub first, just in case

call set_values

Msgbox example(5)

Perhaps is not the most correct way, but I hope it works for you

give this a try,

insert into tableName (ImageColumn) 
SELECT BulkColumn 
FROM Openrowset( Bulk 'image..Path..here', Single_Blob) as img

INSERTING

REFRESHING THE TABLE

Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:

using System;
using System.IO;
using System.Text;

class Program {
    static void Main(string[] args) {
        // Read the file into <bits>
        var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
        var len = (int)fs.Length;
        var bits = new byte[len];
        fs.Read(bits, 0, len);
        // Dump 16 bytes per line
        for (int ix = 0; ix < len; ix += 16) {
            var cnt = Math.Min(16, len - ix);
            var line = new byte[cnt];
            Array.Copy(bits, ix, line, 0, cnt);
            // Write address + hex + ascii
            Console.Write("{0:X6}  ", ix);
            Console.Write(BitConverter.ToString(line));
            Console.Write("  ");
            // Convert non-ascii characters to .
            for (int jx = 0; jx < cnt; ++jx)
                if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
            Console.WriteLine(Encoding.ASCII.GetString(line));
        }
        Console.ReadLine();
    }
}

As all the above answers have suggested it will throw a NullPointerException.

Please initialise it with some value(s) and then you can use the length property correctly. For example:

String[] str = { "plastic", "paper", "use", "throw" };
System.out.println("Length is:::" + str.length);

The array 'str' is now defined, and so it's length also has a defined value.

Here is a macro I use to get the maximum value for signed integers, which is independent of the size of the signed integer type used, and for which gcc -Woverflow won't complain

#define SIGNED_MAX(x) (~(-1 << (sizeof(x) * 8 - 1)))

int a = SIGNED_MAX(a);
long b = SIGNED_MAX(b);
char c = SIGNED_MAX(c); /* if char is signed for this target */
short d = SIGNED_MAX(d);
long long e = SIGNED_MAX(e);

Its just that you need multiple When for a single case to behave it like if.. Elseif else..

   Case when 1=1       //if
   Then
    When 1=1              //else if
     Then.... 
    When .....              //else if
    Then 
    Else                      //else
   ....... 
     End

Just add the following code before presenting your action sheet:

if let popoverController = optionMenu.popoverPresentationController {
    popoverController.sourceView = self.view
    popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
    popoverController.permittedArrowDirections = []
}

For radioButton use

radio1.setChecked(true);

It does not make sense to have just one RadioButton. If you have more of them you need to uncheck others through

radio2.setChecked(false); ...

If your setting is just on/off use CheckBox.

t = setTimeout(function() { rotate(++degree); },65);

and clearTimeout to stop

clearTimeout(t);

I use this with AJAX

success:function(){ clearTimeout(t); }

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

create view sal as
select yr,count(*) as ct from
(select title,yr from movie m, actor a, casting c

and a.id=c.actorid

select yr from sal
where ct =(select max(ct) from sal)

The following solution worked well for me in various environments:

sourceDir="some/directory"
targetDir="any/other/directory"

find "$sourceDir" -type d | sed -e "s?$sourceDir?$targetDir?" | xargs mkdir -p

In my case the following tsconfig.json solved problem:

{
  "compilerOptions": {
    "esModuleInterop": true,
    "target": "ES2020",
    "moduleResolution": "node"
  }
}

There should be no type: module in package.json.

We request that the developer asking for the pull request state that they would like the branch deleted. Most of the time this is the case. There are times when a branch is needed (e.g. copying the changes to another release branch).

My fingers have memorized our process:

git checkout <feature-branch>
git pull
git checkout <release-branch>
git pull
git merge --no-ff <feature-branch>
git push
git tag -a branch-<feature-branch> -m "Merge <feature-branch> into <release-branch>"
git push --tags
git branch -d <feature-branch>
git push origin :<feature-branch>

A branch is for work. A tag marks a place in time. By tagging each branch merge we can resurrect a branch if that is needed. The branch tags have been used several times to review changes.

I also had this issue. Here's how is resolved this

• Exclude bin folder from project.
• Close visual studio.
• Disk cleanup of C drive.
• Re-open project in visual studio.
• And then rebuild solution.
• Run project.

This process is works for me.

You can write in a file by the following code example:

var data = [{ 'test': '123', 'test2': 'Lorem Ipsem ' }];
fs.open(datapath + '/data/topplayers.json', 'wx', function (error, fileDescriptor) {
  if (!error && fileDescriptor) {
    var stringData = JSON.stringify(data);
    fs.writeFile(fileDescriptor, stringData, function (error) {
      if (!error) {
        fs.close(fileDescriptor, function (error) {
          if (!error) {
            callback(false);
          } else {
            callback('Error in close file');
          }
        });
      } else {
        callback('Error in writing file.');
      }
    });
  }
});

You need to scp something somewhere. You have scp ./styles/, so you're saying secure copy ./styles/, but not where to copy it to.

Generally, if you want to download, it will go:

# download: remote -> local
scp user@remote_host:remote_file local_file 

where local_file might actually be a directory to put the file you're copying in. To upload, it's the opposite:

# upload: local -> remote
scp local_file user@remote_host:remote_file

If you want to copy a whole directory, you will need -r. Think of scp as like cp, except you can specify a file with user@remote_host:file as well as just local files.

Edit: As noted in a comment, if the usernames on the local and remote hosts are the same, then the user can be omitted when specifying a remote file.

You could just add one needed external jar file to the project. Go to your project-->java build path-->libraries, add external JARS.Then add your downloaded file from the formal website. My default name is commons-codec-1.10.jar

You can use setCustomValidity function when oninvalid event occurs.

Like below:-

<input class="form-control" type="email" required="" 
    placeholder="username" oninvalid="this.setCustomValidity('Please Enter valid email')">
</input>

Update:-

To clear the message once you start entering use oninput="setCustomValidity('') attribute to clear the message.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

The following function does the trick and keeps all the attributes. You use it for example like this: changeTag("div", "p")

function changeTag(originTag, destTag) {
  while($(originTag).length) {
    $(originTag).replaceWith (function () {
      var attributes = $(this).prop("attributes");
      var $newEl = $(`<${destTag}>`)
      $.each(attributes, function() {
        $newEl.attr(this.name, this.value);
      });  
      return $newEl.html($(this).html())
    })
  }
}

To be sure that it works, check the following example

function changeTag(originTag, destTag) {_x000D_
  while($(originTag).length) {_x000D_
    $(originTag).replaceWith (function () {_x000D_
      var attributes = $(this).prop("attributes");_x000D_
      var $newEl = $(`<${destTag}>`)_x000D_
      $.each(attributes, function() {_x000D_
        $newEl.attr(this.name, this.value);_x000D_
      });  _x000D_
      return $newEl.html($(this).html())_x000D_
    })_x000D_
  }_x000D_
}_x000D_

You need to do this to display image

$sqlimage  = "SELECT image FROM userdetail where `id` = $id1";
$imageresult1 = mysql_query($sqlimage);

while($rows=mysql_fetch_assoc($imageresult1))
{
    $image = $rows['image'];
    echo "<img src='$image' >";
    echo "<br>";
} 

You need to use html img tag.

Need to keep

1.android:maxLines="no of lines"

2.And use \n for getting of the next Lines

1) Go to your project and find ".settings" directory this one
2) Open file xml named:
org.eclipse.wst.common.project.facet.core.xml
3)

<?xml version="1.0" encoding="UTF-8"?>
    <faceted-project>
    <fixed facet="wst.jsdt.web"/>
    <installed facet="java" version="1.5"/>
    <installed facet="jst.web" version="2.3"/>
    <installed facet="wst.jsdt.web" version="1.0"/>
 </faceted-project>

Change jst.web version to 3.0 and java version to 1.7 or 1.8 (base on your current using jdk version)

4) Change your web.xml file under WEB-INF directory , please refer to this article:
https://www.mkyong.com/web-development/the-web-xml-deployment-descriptor-examples/
5) Go to pom.xml file and paste these lines:

Both result.class.to_s and result.class.name work.

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

You're trying to pass file objects as filenames. Try using

infile = '110331_HS1A_1_rtTA.result'
outfile = '2.txt'

at the top of your code.

(Not only does the doubled usage of open() cause that problem with trying to open the file again, it also means that infile and outfile are never closed during the course of execution, though they'll probably get closed once the program ends.)

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

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

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

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

        alertClient
                .setOnDismissListener(new DialogInterface.OnDismissListener() {

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

                    }
                });
        return true;

SET A uses short-circuiting boolean operators.

What 'short-circuiting' means in the context of boolean operators is that for a set of booleans b1, b2, ..., bn, the short circuit versions will cease evaluation as soon as the first of these booleans is true (||) or false (&&).

For example:

// 2 == 2 will never get evaluated because it is already clear from evaluating
// 1 != 1 that the result will be false.
(1 != 1) && (2 == 2)

// 2 != 2 will never get evaluated because it is already clear from evaluating
// 1 == 1 that the result will be true.
(1 == 1) || (2 != 2)

I had a similar requirement a while back. Its nothing to do with Guava but you can do something like this to be able to cleanly construct a Map using a fluent builder.

Create a base class that extends Map.

public class FluentHashMap<K, V> extends LinkedHashMap<K, V> {
    private static final long serialVersionUID = 4857340227048063855L;

    public FluentHashMap() {}

    public FluentHashMap<K, V> delete(Object key) {
        this.remove(key);
        return this;
    }
}

Then create the fluent builder with methods that suit your needs:

public class ValueMap extends FluentHashMap<String, Object> {
    private static final long serialVersionUID = 1L;

    public ValueMap() {}

    public ValueMap withValue(String key, String val) {
        super.put(key, val);
        return this;
    }

... Add withXYZ to suit...

}

You can then implement it like this:

ValueMap map = new ValueMap()
      .withValue("key 1", "value 1")
      .withValue("key 2", "value 2")
      .withValue("key 3", "value 3")

Simply put OAuth is a way for applications to gain credentials to your information without directly getting your user login information to some website. For example if you write an application on your own website and want it to use data from a user's facebook account, you can use OAuth to get a token via a callback url and then use that token to make calls to the facebook API to get their use data until the token expires. Websites rely on it because it allows programmers to access their data without the user having to directly disclose their information and spread their credentials around online but still provide a level of protection to the data. Will it become the de facto method of authorization? Perhaps, it's been gaining a lot of support recently from Twitter, Facebook, and the likes where other programmers want to build applications around user data.

As above.

I use stringbuilder.append().

Very straightforward, and you can then do xmldocument.load(strinbuilder object as parameter).

You will probably find yourself using string.concat within the append parameter, but this is a very straightforward approach.

The problem was the notify filters. The program was trying to open a file that was still copying. I removed all of the notify filters except for LastWrite.

private void watch()
{
  FileSystemWatcher watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastWrite;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);
  watcher.EnableRaisingEvents = true;
}

    android:background="@drawable/bg_edittext"/>

I tried updating and it didn't work. Finally , I had to completely remove (manually )cocoapods, cocoapods-core , cocoapods-try.. and any other package used by cocoapods. Use this terminal command to list all the packages:

gem list --local | grep cocoapods

After that , I also deleted ./cocoapods folder from the user's root folder.

I use freeware called "GS Timer".

Just make a batch file like this:

timer
yourapp.exe
timer /s

If you need a set of times, just pipe the output of timer /s into a .txt file.

I builded another fork of @klewis' code sample to demonstrate some playing with pure css and gradients by using :before/:after pseudo elements and a hidden radio input button.

HTML:

sample radio buttons:
<div style="background:lightgrey;">
    <span class="radio-item">
        <input type="radio" id="ritema" name="ritem" class="true" value="ropt1" checked="checked">
        <label for="ritema">True</label>
    </span>

    <span class="radio-item">
        <input type="radio" id="ritemb" name="ritem" class="false" value="ropt2">
        <label for="ritemb">False</label>
    </span>
</div>

:

CSS:

.radio-item input[type='radio'] {
    visibility: hidden;
    width: 20px;
    height: 20px;
    margin: 0 5px 0 5px;
    padding: 0;

    .radio-item input[type=radio]:before {

Something like this? Takes advantage of short-circuit evaluation. If the file does not exist, the whole conditional cannot be true, so python will not bother evaluation the second part.

os.path.exists("gogogo.php") and os.remove("gogogo.php")

document.getElementById('myRadio').checked is a boolean value. It should be true or false

document.getElementById('myRadio').checked = "checked"; casts the string to a boolean, which is true.

document.getElementById('myRadio').checked = true; just assigns true without casting.

Use true as it is marginally more efficient and is more intention revealing to maintainers.

I have been using [attr.disabled] because I still like this template driven than programmatic enable()/disable() as it is superior IMO.

Change

<md-input formControlName="id" placeholder="ID" [disabled]="true"></md-input>

to

<md-input formControlName="id" placeholder="ID" [attr.disabled]="true"></md-input>

If you are on newer material change md-input to mat-input.

Lawrence has given you a good answer. But if you want more control over what gets exported to where in Excel see Modules: Sample Excel Automation - cell by cell which is slow and Modules: Transferring Records to Excel with Automation You can do things such as export the recordset starting in row 2 and insert custom text in row 1. As well as any custom formatting required.

Expanding Rentering.com's answer, in scenarios where a whole graph of many types is to be taken care of, and you're looking for a strongly typed solution, this class can help, see usage (fluent) below. It operates as either a black-list or white-list per type. A type cannot be both (Gist - also contains global ignore list).

public class PropertyFilterResolver : DefaultContractResolver
{
  const string _Err = "A type can be either in the include list or the ignore list.";
  Dictionary<Type, IEnumerable<string>> _IgnorePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  Dictionary<Type, IEnumerable<string>> _IncludePropertiesMap = new Dictionary<Type, IEnumerable<string>>();
  public PropertyFilterResolver SetIgnoredProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null) return this;

    if (_IncludePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IgnorePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  public PropertyFilterResolver SetIncludedProperties<T>(params Expression<Func<T, object>>[] propertyAccessors)
  {
    if (propertyAccessors == null)
      return this;

    if (_IgnorePropertiesMap.ContainsKey(typeof(T))) throw new ArgumentException(_Err);

    var properties = propertyAccessors.Select(GetPropertyName);
    _IncludePropertiesMap[typeof(T)] = properties.ToArray();
    return this;
  }

  protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
  {
    var properties = base.CreateProperties(type, memberSerialization);

    var isIgnoreList = _IgnorePropertiesMap.TryGetValue(type, out IEnumerable<string> map);
    if (!isIgnoreList && !_IncludePropertiesMap.TryGetValue(type, out map))
      return properties;

    Func<JsonProperty, bool> predicate = jp => map.Contains(jp.PropertyName) == !isIgnoreList;
    return properties.Where(predicate).ToArray();
  }

  string GetPropertyName<TSource, TProperty>(
  Expression<Func<TSource, TProperty>> propertyLambda)
  {
    if (!(propertyLambda.Body is MemberExpression member))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a method, not a property.");

    if (!(member.Member is PropertyInfo propInfo))
      throw new ArgumentException($"Expression '{propertyLambda}' refers to a field, not a property.");

    var type = typeof(TSource);
    if (!type.GetTypeInfo().IsAssignableFrom(propInfo.DeclaringType.GetTypeInfo()))
      throw new ArgumentException($"Expresion '{propertyLambda}' refers to a property that is not from type '{type}'.");

    return propInfo.Name;
  }
}

Usage:

var resolver = new PropertyFilterResolver()
  .SetIncludedProperties<User>(
    u => u.Id, 
    u => u.UnitId)
  .SetIgnoredProperties<Person>(
    r => r.Responders)
  .SetIncludedProperties<Blog>(
    b => b.Id)
  .Ignore(nameof(IChangeTracking.IsChanged)); //see gist

The answers given so far that have received the most votes are relying on NSString methods and are going to require that you have imported Foundation.

Having done that, though, you still have access to NSLog.

So I think the answer to the question, if you are asking how to continue using NSLog in Swift, is simply:

import Foundation

Thanks to gene tsai, here is some modifications to his code to run on my target page:

csv = []
rows = $('#data tr');
for(i =0;i < rows.length;i++) {
    cells = $(rows[i]).find('td,th');
    csv_row = [];
    for (j=0;j<cells.length;j++) {
        txt = cells[j].innerText;
        csv_row.push(txt.replace(",", "-"));
    }
    csv.push(csv_row.join(","));
}
output = csv.join("\n")

improvements:

• Use generic JavaScript for loop
• make sure each cell does not have a comma

You can just put:

header("HTTP/1.0 500 Internal Server Error");

inside your conditions like:

if (that happened) {
    header("HTTP/1.0 500 Internal Server Error");
}

As for the database query, you can just do that like this:

$result = mysql_query("..query string..") or header("HTTP/1.0 500 Internal Server Error");

You should remember that you have to put this code before any html tag (or output).

The definitive answer to this is from Facebook themselves. In post today at https://developers.facebook.com/bugs/335452696581712 a Facebook dev says

The ability to pass in an e-mail address into the "user" search type was
removed on July 10, 2013. This search type only returns results that match
a user's name (including alternate name).

So, alas, the simple answer is you can no longer search for users by their email address. This sucks, but that's Facebook's new rules.

Changing port number has resolved the issue

Aptana supports this and I use it for all of my web development now.

One of the aspects of .NET I like the most are generics. Even if you write procedural code in F#, you will still benefit from type inference. It makes writing generic code easy.

In C#, you write concrete code by default, and you have to put in some extra work to write generic code.

In F#, you write generic code by default. After spending over a year of programming in both F# and C#, I find that library code I write in F# is both more concise and more generic than the code I write in C#, and is therefore also more reusable. I miss many opportunities to write generic code in C#, probably because I'm blinded by the mandatory type annotations.

There are however situations where using C# is preferable, depending on one's taste and programming style.

• C# does not impose an order of declaration among types, and it's not sensitive to the order in which files are compiled.
• C# has some implicit conversions that F# cannot afford because of type inference.

There are several issues:

1. Class names (and IDs) are not allowed to start with a digit.
2. You have to pass a class to getElementsByClassName().
3. You have to iterate of the result set.

Example (untested):

<script type="text/javascript">
function hideTd(className){
    var elements = document.getElementsByClassName(className);
    for(var i = 0, length = elements.length; i < length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>
</head>
<body onload="hideTd('td');">
<table border="1">
  <tr>
    <td class="td">not empty</td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
</table>
</body>

Note that getElementsByClassName() is not available up to and including IE8.

Update:

Alternatively you can give the table an ID and use:

var elements = document.getElementById('tableID').getElementsByTagName('td');

to get all td elements.

To hide the parent row, use the parentNode property of the element:

elements[i].parentNode.style.display = "none";

Actually johann, the # indicates that it's a preprocessor directive, which basically means it tells the IDE what to do.

In the case of using #region and #endregion in your code, it makes NO difference in the final code whether it's there or not. Can you really call it a language element if using it changes nothing?

Apart from that, java doesn't have preprocessor directives, which means the option of code folding is defined on a per-ide basis, in netbeans for example with a //< code-fold> statement

Bullets take the color property of the list:

.listStyle {
    color: red;
}

Note if you want your list text to be a different colour, you have to wrap it in say, a p, for example:

.listStyle p {
    color: black;
}

Example HTML:

<ul class="listStyle">
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
    <li>
        <p><strong>View :</strong> blah blah.</p>
    </li>
</ul>

Starting with the given:

• There are 72 points in an inch (that is what a point is, 1/72 of an inch)
• on a system set for 150dpi, there are 150 pixels per inch.
• 1 in = 72pt = 150px (for 150dpi setting)

If you want to find points (pt) based on pixels (px):

 72 pt    x pt
------ = -----                  (1) for 150dpi system
150 px    y px

Rearranging:

x = (y/150) * 72                (2) for 150dpi system

so:

points = (pixels / 150) * 72    (3) for 150dpi system

I wrote an article on this on my blog: http://www.ebenmonney.com/blog/how-to-implement-remember-me-functionality-using-token-based-authentication-and-localstorage-in-a-web-application .

Using a library I created storageManager you can achieve this as follows:

storageManager.savePermanentData('data', 'key'): //saves permanent data
storageManager.saveSyncedSessionData('data', 'key'); //saves session data to all opened tabs
storageManager.saveSessionData('data', 'key'); //saves session data to current tab only
storageManager.getData('key'); //retrieves data

There are other convenient methods as well to handle other scenarios as well

Try this :

$('#form1').submit();

or

document.form1.submit();

private OutputStream outputStream;
private InputStream inStream;

private void init() throws IOException {
    BluetoothAdapter blueAdapter = BluetoothAdapter.getDefaultAdapter();
    if (blueAdapter != null) {
        if (blueAdapter.isEnabled()) {
            Set<BluetoothDevice> bondedDevices = blueAdapter.getBondedDevices();

            if(bondedDevices.size() > 0) {
                Object[] devices = (Object []) bondedDevices.toArray();
                BluetoothDevice device = (BluetoothDevice) devices[position];
                ParcelUuid[] uuids = device.getUuids();
                BluetoothSocket socket = device.createRfcommSocketToServiceRecord(uuids[0].getUuid());
                socket.connect();
                outputStream = socket.getOutputStream();
                inStream = socket.getInputStream();
            }

            Log.e("error", "No appropriate paired devices.");
        } else {
            Log.e("error", "Bluetooth is disabled.");
        }
    }
}

public void write(String s) throws IOException {
    outputStream.write(s.getBytes());
}

public void run() {
    final int BUFFER_SIZE = 1024;
    byte[] buffer = new byte[BUFFER_SIZE];
    int bytes = 0;
    int b = BUFFER_SIZE;

    while (true) {
        try {
            bytes = inStream.read(buffer, bytes, BUFFER_SIZE - bytes);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Here is a simple code for javascript validation, and after it validates it will clean the input file.

<input type="file" id="image" accept="image/*" onChange="validate(this.value)"/>

function validate(file) {
    var ext = file.split(".");
    ext = ext[ext.length-1].toLowerCase();      
    var arrayExtensions = ["jpg" , "jpeg", "png", "bmp", "gif"];

    if (arrayExtensions.lastIndexOf(ext) == -1) {
        alert("Wrong extension type.");
        $("#image").val("");
    }
}

I was able to fix by manually adding the junit jar to my project classpath. The easiest way I found to do this was by adding a /lib directory in the project root. Then i just put the junit.jar inside /lib and junit tests starting working for me.

Check out this blog post here that talks about the same thing. From what I gather, the extra time might have to do with walking up the scope chain.

I prefer the answers a and b above using functools.reduce() and the answer using numpy.prod(), but here is yet another solution using itertools.accumulate():

import itertools
import operator
prod = list(itertools.accumulate((3, 4, 5), operator.mul))[-1]

There is a built-in function... try

$ __git_aliases

lists all the aliases :)

uint32_t is defined in the standard, in

18.4.1 Header <cstdint> synopsis [cstdint.syn]

namespace std {
//...
typedef unsigned integer type uint32_t; // optional
//...
}

uint32 is not, it's a shortcut provided by some compilers (probably as typedef uint32_t uint32) for ease of use.

You have to enable null value for your date variable :

 public Nullable<DateTime> MyDate{ get; set; }

Note: the question was originally about compilation time, but later it turned out that the OP really meant execution time. But maybe this answer will still be useful for someone.

For Visual Studio: go to Tools / Options / Projects and Solutions / VC++ Project Settings and set Build Timing option to 'yes'. After that the time of every build will be displayed in the Output window.

I don't know why everyone is using 2 copies of the same list to solve this. This uses too much RAM...

Why not just hide the elements that are not found, and simply store their index in a Set to be able to restore them later? That's much less RAM especially if your objects are quite large.

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.SampleViewHolders>{
    private List<MyObject> myObjectsList; //holds the items of type MyObject
    private Set<Integer> foundObjects; //holds the indices of the found items

    public MyRecyclerViewAdapter(Context context, List<MyObject> myObjectsList)
    {
        this.myObjectsList = myObjectsList;
        this.foundObjects = new HashSet<>();
        //first, add all indices to the indices set
        for(int i = 0; i < this.myObjectsList.size(); i++)
        {
            this.foundObjects.add(i);
        }
    }

    @Override

        View layoutView = LayoutInflater.from(parent.getContext()).inflate(

        MyRecyclerViewAdapter.SampleViewHolders rcv = new MyRecyclerViewAdapter.SampleViewHolders(layoutView);
        return rcv;
    }

    @Override
    public void onBindViewHolder(@NonNull SampleViewHolders holder, int position)
    {
        //look for object in O(1) in the indices set
        if(!foundObjects.contains(position))
        {

        //holder.nameTextView.setText(...)
    }

            //if it's empty text, we want all objects, so just add it to the set.
            if(text.length() == 0)
            {
                foundObjects.add(i);
            }
            else
            {
                //otherwise check if it meets your search criteria and add it or remove it accordingly
                if (myObjectsList.get(i).getName().toLowerCase().contains(text.toLowerCase()))
                {
                    foundObjects.add(i);
                }
                else
                {
                    foundObjects.remove(i);
                }
            }
        }
        notifyDataSetChanged();
    }

    public class SampleViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener
    {
        public ImageView imgImageView;
        public TextView nameTextView;

        private final CardView layout;
        private final CardView.LayoutParams hiddenLayoutParams;
        private final CardView.LayoutParams shownLayoutParams;

        
        public SampleViewHolders(View itemView)
        {
            super(itemView);
            itemView.setOnClickListener(this);
            imgImageView = (ImageView) itemView.findViewById(R.id.some_image_view);
            nameTextView = (TextView) itemView.findViewById(R.id.display_name_textview);

            layout = itemView.findViewById(R.id.card_view); //card_view is the id of my androidx.cardview.widget.CardView in my xml layout
            //prepare hidden layout params with height = 0, and visible layout params for later - see hideLayout() and showLayout()
            hiddenLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            hiddenLayoutParams.height = 0;
            shownLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
        }

        @Override
        public void onClick(View view)
        {
            //implement...
        }

        private void hideLayout() {
            //hide the layout
            layout.setLayoutParams(hiddenLayoutParams);
        }

        private void showLayout() {
            //show the layout
            layout.setLayoutParams(shownLayoutParams);
        }
    }
}

And I simply have an EditText as my search box:

cardsSearchTextView.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                myViewAdapter.findObject(editable.toString().toLowerCase());
            }
        });

Result:

With Python 3, how about:

try:
    with open(filename, 'x') as tempfile: # OSError if file exists or is invalid
        pass
except OSError:
    # handle error here

With the 'x' option we also don't have to worry about race conditions. See documentation here.

Now, this WILL create a very shortlived temporary file if it does not exist already - unless the name is invalid. If you can live with that, it simplifies things a lot.

@webdeb's answer didn't work for me, I hit an unexpected token error when compiling ES6 with Babel, doing named default exports.

This worked for me, however:

// Foo.js
export default Foo
...

// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
...

// and import somewhere..
import { Foo, Bar } from './bundle'

Rather than adding a callback to ServicePointManager which will override certificate validation globally, you can set the callback on a local instance of HttpClient. This approach should only affect calls made using that instance of HttpClient.

Here is sample code showing how ignoring certificate validation errors for specific servers might be implemented in a Web API controller.

using System.Net.Http;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

public class MyController : ApiController
{

    // use this HttpClient instance when making calls that need cert errors suppressed
    private static readonly HttpClient httpClient;

    static MyController()
    {
        // create a separate handler for use in this controller
        var handler = new HttpClientHandler();

        // add a custom certificate validation callback to the handler
        handler.ServerCertificateCustomValidationCallback = ((sender, cert, chain, errors) => ValidateCert(sender, cert, chain, errors));

        // create an HttpClient that will use the handler
        httpClient = new HttpClient(handler);
    }

    protected static ValidateCert(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors errors)
    {

        // set a list of servers for which cert validation errors will be ignored
        var overrideCerts = new string[]
        {
            "myproblemserver",
            "someotherserver",
            "localhost"
        };

        // if the server is in the override list, then ignore any validation errors
        var serverName = cert.Subject.ToLower();
        if (overrideCerts.Any(overrideName => serverName.Contains(overrideName))) return true;

        // otherwise use the standard validation results
        return errors == SslPolicyErrors.None;
    }

}

As noted above, it appears that the cover photo of the profile album is a hi-res profile picture. I would check for the album type of "profile" rather than the name though, as the name may not be consistent across different languages, but the type should be.

To reduce the number of requests / parsing, you can use this fql: "select cover_object_id from album where type='profile' and owner = user_id"

And then you can construct the image url with: "https://graph.facebook.com/" + cover_object_id + "/picture&type=normal&access_token=" + access_token

Looks like there is no "large" type for this image, but the "normal" one is still quite large.

As noted above, this photo may be less accessible than the public profile picture. You need the user_photos or friend_photos permission to access it.

You can also use

 - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
  {

   [self.yourTextField resignFirstResponder];

  }

Best one if You have many Uitextfields :

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
 {    
     [self.view endEditing:YES];
 }

1. Try with echo %path% , if this option doesn't show your M2_HOME and others variable values as directory path, then create a new environment variable lets say PATH, and assign like below:

   PATH=%JAVA_HOME%\bin;%M2_HOME%\bin
   

2. Add this in variable path=.....;%PATH%

3. Now open a new cmd, and try to echo %path%
   it will show all thh system path

Now you can check mvn -version it will solve the problem , if not try to restart the system

P.S. as per doc, you should expend your zip distribution in C:\Program Files\Apache Software Foundation. But ideally it doen't matter

Basically you need to edit the JS and add (in this case, inside $('#featured-articles').slick({ ), this:

variableWidth: true,

This will allow you to edit the width in your CSS where you can, generically use:

.slick-slide {
    width: 100%;
}

or in this case:

.featured {
    width: 100%;
}

As indicated here, the general syntax for the first solution proposed by Tony Andrews is :

update some_table s
set   (s.col1, s.col2) = (select x.col1, x.col2
                          from   other_table x
                          where  x.key_value = s.key_value
                         )
where exists             (select 1
                          from   other_table x
                          where  x.key_value = s.key_value
                         )

I think this is interesting especially if you want update more than one field.

you try something like that,in your .aspx page

add

EnableEventValidation="false"

you feel free to ask any question!

If a member is a Array it will be a little bit complex than the normal is:

class C
{
    static const int ARRAY[10];
 public:
    C() {}
};
const unsigned int C::ARRAY[10] = {0,1,2,3,4,5,6,7,8,9};

or

int* a = new int[N];
// fill a

class C {
  const std::vector<int> v;
public:
  C():v(a, a+N) {}
};

Add list-style-position: inside to the ul element. (example)

The default value for the list-style-position property is outside.

ul {_x000D_
    text-align: center;_x000D_
    list-style-position: inside;_x000D_
}

<ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
</ul>

Another option (which yields slightly different results) would be to center the entire ul element:

.parent {_x000D_
  text-align: center;_x000D_
}_x000D_
.parent > ul {_x000D_
  display: inline-block;_x000D_
}

<div class="parent">_x000D_
  <ul>_x000D_
    <li>one</li>_x000D_
    <li>two</li>_x000D_
    <li>three</li>_x000D_
  </ul>_x000D_
</div>

This has been fully answered here.

See Oracle's docs on SELECT to see how subquery factoring works, and Mark's example:

WITH employee AS (SELECT * FROM Employees)
SELECT * FROM employee WHERE ID < 20
UNION ALL
SELECT * FROM employee WHERE Sex = 'M'

You want to create an empty list, then append the created list to it. This will give you the list of lists. Example:

>>> l = []
>>> l.append([1,2,3])
>>> l.append([4,5,6])
>>> l
[[1, 2, 3], [4, 5, 6]]

A bit late but as this is an ongoing issue with Mac OSX...

The simplest solution I found was to simply remove the OpenJDK stuff that Apple installs. Every time an update of Mac OSX arrives it gets installed and you'll need to remove it again.

This works really well if you develop apps for Google App Engine on your mac using Java. The OpenJDK does not work well and the Java version that comes with the Mac OSX Yosemite upgrade will make the Eclipse Plug-in for App Engine crash on every deployment with the helpful error: "Read timed out".

Private Function LoaderData(ByVal strSql As String) As DataTable
    Dim cnn As SqlConnection
    Dim dad As SqlDataAdapter

    Dim dtb As New DataTable
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        dad = New SqlDataAdapter(strSql, cnn)
        dad.Fill(dtb)
        cnn.Close()
        dad.Dispose()
    Catch ex As Exception
        cnn.Close()

    Return dtb
End Function

This has happened to me . Jquery version : 3.3. If you are looping through a list of objects, and want to add each object as a child of some parent dom element, then .html and .append will behave very different. .html will end up adding only the last object to the parent element, whereas .append will add all the list objects as children of the parent element.

function abc() {
    var color = document.getElementById("test").style.color;
    color = (color=="red") ? "black" : "red" ;
    document.getElementById("test").style.color= color;
}

The way via unlist and matrix seems a bit convoluted, and requires you to hard-code the number of elements (this is actually a pretty big no-go. Of course you could circumvent hard-coding that number and determine it at run-time)

I would go a different route, and construct a data frame directly from the list that strsplit returns. For me, this is conceptually simpler. There are essentially two ways of doing this:

1. as.data.frame – but since the list is exactly the wrong way round (we have a list of rows rather than a list of columns) we have to transpose the result. We also clear the rownames since they are ugly by default (but that’s strictly unnecessary!):

   `rownames<-`(t(as.data.frame(strsplit(text, '\\.'))), NULL)
   

2. Alternatively, use rbind to construct a data frame from the list of rows. We use do.call to call rbind with all the rows as separate arguments:

   do.call(rbind, strsplit(text, '\\.'))
   

Both ways yield the same result:

     [,1] [,2] [,3]  [,4]
[1,] "F"  "US" "CLE" "V13"
[2,] "F"  "US" "CA6" "U13"
[3,] "F"  "US" "CA6" "U13"
[4,] "F"  "US" "CA6" "U13"
[5,] "F"  "US" "CA6" "U13"
[6,] "F"  "US" "CA6" "U13"
…

Clearly, the second way is much simpler than the first.

Unfortunately, this is not currently possible in the latest version of DataContractJsonSerializer. See: http://connect.microsoft.com/VisualStudio/feedback/details/558686/datacontractjsonserializer-should-serialize-dictionary-k-v-as-a-json-associative-array

The current suggested workaround is to use the JavaScriptSerializer as Mark suggested above.

Good luck!

Convert an iterable to a list may have a cost. Instead, to get the the first item, you can use:

next(iter(keys))

Or, if you want to iterate over all items, you can use:

items = iter(keys)
while True:
    try:
        item = next(items)
    except StopIteration as e:
        pass # finish

You can use the Session object

import requests
headers = {'User-Agent': 'Mozilla/5.0'}
payload = {'username':'niceusername','password':'123456'}

session = requests.Session()
session.post('https://admin.example.com/login.php',headers=headers,data=payload)
# the session instance holds the cookie. So use it to get/post later.
# e.g. session.get('https://example.com/profile')

You can do this by adding a parameter &hd=1 to the video URL. That forces the video to start in the highest resolution available for the video. However you cannot specifically set it to 720p, because not every video has that hd ish.

http://www.youtube.com/watch?v=VIDEO_ID&hd=1

UPDATE: as of 2014, hd is deprecated https://developers.google.com/youtube/player_parameters?csw=1#Deprecated_Parameters

If a profiler is not applicable in your setup, you may try to identify the thread following steps in this post.

Basically, there are three steps:

1. run top -H and get PID of the thread with highest CPU.
2. convert the PID to hex.
3. look for thread with the matching HEX PID in your thread dump.

Your question implies that you're willing to modify other parts of the code, even though you can't modify the SQL Statement itself. Instead of removing them from the ListBox Collection, it might be easier to just exclude them in the first place. This code assumes you're connecting to SQL Server:

void PopulateListBox(ListBox listToPopulate)
{
    SqlConnection conn = new SqlConnection("myConnectionString"); 
    SqlCommand cmd = new SqlCommand("spMyStoredProc", conn);
    cmd.CommandType = CommandType.StoredProcedure;
    SqlDataReader reader = cmd.ExecuteReader();
    while (reader.Read())
    {
        string item = reader.GetString(0); //or whatever column is displayed in the list
        if (!item.Contains("OBJECT_"))
            listToPopulate.Items.Add(item); 
    }
}

But if you're absolutely determined to do it this way you should check out this question on modifying an enumerable collection while iterating through it.

If you ARE very very lazy, you can put the values inside an array. Such as

list = []
list.append(x)
list.append(y)
list.append(z)
nums = [add numbers here]
letters = [add corresponding letters here]
for index in range(len(nums)):
    for obj in list:
        if obj == num[index]:
            MyList.append(letters[index])
            break

You can also put the numbers and letters in a dictionary and do it, but this is probably a LOT more complicated than simply if statements. That's what you get for trying to be extra lazy :)

One more thing, your

if x or y or z == 0:

will compile, but not in the way you want it to. When you simply put a variable in an if statement (example)

if b

the program will check if the variable is not null. Another way to write the above statement (which makes more sense) is

if bool(b)

Bool is an inbuilt function in python which basically does the command of verifying a boolean statement (If you don't know what that is, it is what you are trying to make in your if statement right now :))

Another lazy way I found is :

if any([x==0, y==0, z==0])

To exclude everything in a directory, but some sub-directories, do the following:

Your title and comments imply that you weren't looking for a sticky footer (stuck to the bottom of the window as content scrolls below it). I assume you were looking for a footer that would be forced to the bottom of the window if the content does not fill the window, and push down to the bottom of the content if the content exceeds the window boundary.

You can accomplish this with the following.

<style>
html,
body {
    margin:0;
    padding:0;
    height:100%;
}
#container {
    min-height:100%;
    position:relative;
}
#header {
    background:#ff0;
    padding:10px;
}
#body {
    padding:10px;
    padding-bottom:60px;   /* Height of the footer */
}
#footer {
    position:absolute;
    bottom:0;
    width:100%;
    height:60px;   /* Height of the footer */
    background:#6cf;
}
</style>

<div id="container">
    <div id="header">header</div>
    <div id="body">body</div>
    <div id="footer">footer</div>
</div>

As MadScientist pointed out, you can export individual variables with:

export MY_VAR = foo  # Available for all targets

Or export variables for a specific target (target-specific variables):

my-target: export MY_VAR_1 = foo
my-target: export MY_VAR_2 = bar
my-target: export MY_VAR_3 = baz

my-target: dependency_1 dependency_2
  echo do something

You can also specify the .EXPORT_ALL_VARIABLES target to—you guessed it!—EXPORT ALL THE THINGS!!!:

.EXPORT_ALL_VARIABLES:

MY_VAR_1 = foo
MY_VAR_2 = bar
MY_VAR_3 = baz

test:
  @echo $$MY_VAR_1 $$MY_VAR_2 $$MY_VAR_3

see .EXPORT_ALL_VARIABLES

Examining the cookies the site gives can reveal the underlying framework. CodeIgniter, for example defaults to a telltale ci_sessions cookie. Sites using PEAR Auth will do something similar.

I didn't find it in the previous answers, so, with Java 8 and streams:

Convert String[] to Integer[]:

Arrays.stream(stringArray).map(Integer::valueOf).toArray(Integer[]::new)

If you want to link, say, libapplejuice statically, but not, say, liborangejuice, you can link like this:

gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary

There's a caveat -- if liborangejuice uses libapplejuice, then libapplejuice will be dynamically linked too.

You'll have to link liborangejuice statically alongside with libapplejuice to get libapplejuice static.

And don't forget to keep -Wl,-Bdynamic else you'll end up linking everything static, including libc (which isn't a good thing to do).

From the "Updating Chosen Dynamically" section in the docs: You need to trigger the 'chosen:updated' event on the field

$(document).ready(function() {

    $('select').chosen();

    $('button').click(function() {
        $('select').val(2);
        $('select').trigger("chosen:updated");
    });

});

NOTE: versions prior to 1.0 used the following:

$('select').trigger("liszt:updated");

I am using phpMyAdmin version 4.2.11. At the time of writing, my Status tab looks like this (a few options expanded; note "Current settings", bottom right):

Note, there are no directly visible "features" that allow for the enabling of things such as slow_query_log. So, I went digging on the internet because UI-oriented answers will only be relevant to a particular release and, therefore, will quickly become out of date. So, what do you do if you don't see a relevant answer, above?

As this article explains, you can run a global query to enable or disable the slow_query_log et al. The queries for enabling and disabling these logs are not difficult, so don't be afraid of them, e.g.

SET GLOBAL slow_query_log = 'ON';

From here, phpMyAdmin is pretty helpful and a bit of Googling will get you up to speed in no time. For instance, after I ran the above query, I can go back to the "Instructions/Setup" option under the Status tab's Monitor window and see this (note the further instructions):

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

\d means 'digit'. + means, '1 or more times'. So \d+ means one or more digit. It will match 12 and 1.

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

i would like to suggest one answer

if we take the first k elements and sort them into a linked list of k values

now for every other value even for the worst case if we do insertion sort for rest n-k values even in the worst case number of comparisons will be k*(n-k) and for prev k values to be sorted let it be k*(k-1) so it comes out to be (nk-k) which is o(n)

cheers

Go to you MainActivity.java and below this code
-> NavigationView navigationView = findViewById(R.id.nav_view);
Add single line of code -> navigationView.setItemIconTintList(null);
i.e. the last line of my code

I hope this might solve your problem.

public class MainActivity extends AppCompatActivity {

    private AppBarConfiguration mAppBarConfiguration;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);
        navigationView.setItemIconTintList(null);

Partially based on Mohsen's answer (the added first condition covers the case where the child is hidden before the parent):

jQuery.fn.isChildOverflowing = function (child) {
  var p = jQuery(this).get(0);
  var el = jQuery(child).get(0);
  return (el.offsetTop < p.offsetTop || el.offsetLeft < p.offsetLeft) ||
    (el.offsetTop + el.offsetHeight > p.offsetTop + p.offsetHeight || el.offsetLeft + el.offsetWidth > p.offsetLeft + p.offsetWidth);
};

Then just do:

jQuery('#parent').isChildOverflowing('#child');

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

The JsonSerializer instance can be configured to ignore reference loops. Like in the following, this function allows to save a file with the content of the json serialized object:

    public static void SaveJson<T>(this T obj, string FileName)
    {
   
       JsonSerializer serializer = new JsonSerializer();
        serializer.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        using (StreamWriter sw = new StreamWriter(FileName))
        {
            using (JsonWriter writer = new JsonTextWriter(sw))
            {
                writer.Formatting = Formatting.Indented;
                serializer.Serialize(writer, obj);
            }
        }
    }

Use array_unshift($array, $item);

$arr = array('item2', 'item3', 'item4');
array_unshift($arr , 'item1');
print_r($arr);

will give you

Array
(
 [0] => item1
 [1] => item2
 [2] => item3
 [3] => item4
)

you can use System.Diagnostics.Process.Start as well as WIN32 ShellExecute function by means of interop, for opening PDF files using the default viewer:

System.Diagnostics.Process.Start("SOMEAPP.EXE","Path/SomeFile.Ext");

[System.Runtime.InteropServices.DllImport("shell32. dll")]
private static extern long ShellExecute(Int32 hWnd, string lpOperation, 
                                    string lpFile, string lpParameters, 
                                        string lpDirectory, long nShowCmd);

Another approach is to place a WebBrowser Control into your Form and then use the Navigate method for opening the PDF file:

ThewebBrowserControl.Navigate(@"c:\the_file.pdf");

Other way with Basic method is:

$curl = curl_init();

$public_key = "public_key";
$private_key = "private_key";

curl_setopt_array($curl, array(
CURLOPT_URL => "https://url.endpoint.co/login",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_HTTPHEADER => array(
"Content-Type: application/json",
"Authorization: Basic ".base64_encode($public_key.":".$private_key)
),
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;

First create an object of class2 in class1 and then use that object to call any function of class2 for example write this in class1

class2 obj= new class2();
obj.thefunctioname(args);

I dont think its a good idea to do that but if you have backup in ur machine.. push one more time and then try cloning repo and then remove .git from old dir and move .git from new cloned folder .. git is resolved but because of the issue some files may not upload at git. Push again all from ur back up and then pull it to ur server or the other machine where it get currupted. Right now i just did thid ... Works for me .. and take a backup of your dir before doing this.

And plz correct me if i am wrong. I also dont know what can go wrong after doing this? But this time it really works.

Check the unsaved values for your primary key/Object ID in your hbm files. If you have automated ID creation by hibernate framework and you are setting the ID somewhere it will throw this error.By default the unsaved value is 0, so if you set the ID to 0 you will see this error.

For Rails 4 - remove the gem name from Gemfile and then run bundle install in your terminal. Also restart the server afterwards.

Symbol You Want on Color You Want!

I was looking for this answer for days and here it is the right and easy way to create a custom marker:

'http://chart.googleapis.com/chart?chst=d_map_pin_letter&chld=xxx%7c5680FC%7c000000&.png' where xxx is the text and 5680fc is the hexadecimal color code of the background and 000000 is the hexadecimal color code of the text.

Theses markers are totally dynamic and you can create whatever balloon icon you want. Just change the URL.

Setting Up the database

public class DatabaseHelper extends SQLiteOpenHelper {
    // Database Version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "database_name";

    // Table Names
    private static final String DB_TABLE = "table_image";

    // column names
    private static final String KEY_NAME = "image_name";
    private static final String KEY_IMAGE = "image_data";

    // Table create statement
    private static final String CREATE_TABLE_IMAGE = "CREATE TABLE " + DB_TABLE + "("+ 
                       KEY_NAME + " TEXT," + 
                       KEY_IMAGE + " BLOB);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {

        // creating table
        db.execSQL(CREATE_TABLE_IMAGE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        // on upgrade drop older tables
        db.execSQL("DROP TABLE IF EXISTS " + DB_TABLE);

        // create new table
        onCreate(db);
    }
}

Insert in the Database:

public void addEntry( String name, byte[] image) throws SQLiteException{
    SQLiteDatabase database = this.getWritableDatabase();
    ContentValues cv = new  ContentValues();
    cv.put(KEY_NAME,    name);
    cv.put(KEY_IMAGE,   image);
    database.insert( DB_TABLE, null, cv );
}

Retrieving data:

 byte[] image = cursor.getBlob(1);

Note:

1. Before inserting into database, you need to convert your Bitmap image into byte array first then apply it using database query.
2. When retrieving from database, you certainly have a byte array of image, what you need to do is to convert byte array back to original image. So, you have to make use of BitmapFactory to decode.

Below is an Utility class which I hope could help you:

public class DbBitmapUtility {

    // convert from bitmap to byte array
    public static byte[] getBytes(Bitmap bitmap) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(CompressFormat.PNG, 0, stream);
        return stream.toByteArray();
    }

    // convert from byte array to bitmap
    public static Bitmap getImage(byte[] image) {
        return BitmapFactory.decodeByteArray(image, 0, image.length);
    }
}

Further reading
If you are not familiar how to insert and retrieve into a database, go through this tutorial.

You have 2 choices:

db.users.find({"name": /string/})

or

db.users.find({"name": {"$regex": "string", "$options": "i"}})

On second one you have more options, like "i" in options to find using case insensitive. And about the "string", you can use like ".string." (%string%), or "string.*" (string%) and ".*string) (%string) for example. You can use regular expression as you want.

Enjoy!

Dynamic programming is a technique used to avoid computing multiple times the same subproblem in a recursive algorithm.

Let's take the simple example of the Fibonacci numbers: finding the n ^th Fibonacci number defined by

F_n = F_n-1 + F_n-2 and F₀ = 0, F₁ = 1

Recursion

The obvious way to do this is recursive:

def fibonacci(n):
    if n == 0:
        return 0
    if n == 1:
        return 1

    return fibonacci(n - 1) + fibonacci(n - 2)

Dynamic Programming

• Top Down - Memoization

The recursion does a lot of unnecessary calculations because a given Fibonacci number will be calculated multiple times. An easy way to improve this is to cache the results:

cache = {}

def fibonacci(n):
    if n == 0:
        return 0
    if n == 1:
        return 1
    if n in cache:
        return cache[n]

    cache[n] = fibonacci(n - 1) + fibonacci(n - 2)

    return cache[n]

• Bottom-Up

A better way to do this is to get rid of the recursion all-together by evaluating the results in the right order:

cache = {}

def fibonacci(n):
    cache[0] = 0
    cache[1] = 1

    for i in range(2, n + 1):
        cache[i] = cache[i - 1] +  cache[i - 2]

    return cache[n]

We can even use constant space and store only the necessary partial results along the way:

def fibonacci(n):
  fi_minus_2 = 0
  fi_minus_1 = 1

  for i in range(2, n + 1):
      fi = fi_minus_1 + fi_minus_2
      fi_minus_1, fi_minus_2 = fi, fi_minus_1

  return fi

• How apply dynamic programming?

  1. Find the recursion in the problem.
  2. Top-down: store the answer for each subproblem in a table to avoid having to recompute them.
  3. Bottom-up: Find the right order to evaluate the results so that partial results are available when needed.

Dynamic programming generally works for problems that have an inherent left to right order such as strings, trees or integer sequences. If the naive recursive algorithm does not compute the same subproblem multiple times, dynamic programming won't help.

I made a collection of problems to help understand the logic: https://github.com/tristanguigue/dynamic-programing

looks like you're better off systeming out to system("grep \"$QUERY\"") since that script won't be particularly high performance either way. Otherwise http://php.net/manual/en/function.file.php shows you how to loop over lines and you can use http://php.net/manual/en/function.strstr.php for finding matches.

This does the trick, without the need to add an inline style

<div class="row-fluid">
    <div class="span6">
        <p>text left</p>
    </div>
    <div class="span6">
        <div class="pull-right">
            <p>text right</p>
        </div>
    </div>
</div>

The answer is in nesting another <div> with the "pull-right" class. Combining the two classes won't work.

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

You can just do:

string myStr = "The quick brown fox jumps over the lazy dog";
string[] ssizes = myStr.Split(' ');

MSDN has more examples and references:

http://msdn.microsoft.com/en-us/library/b873y76a.aspx

Adding to other answers already given above. If case insensivity is of any importance to you, then use Jackson. Gson does not support case insensitivity for key names, while jackson does.

Here are two related links

(No) Case sensitivity support in Gson : GSON: How to get a case insensitive element from Json?

This can be done in two ways.

JLabel Horizontal Alignment

You can use the JLabel constructor:

JLabel(String text, int horizontalAlignment) 

To align to the right:

JLabel label = new JLabel("Telephone", SwingConstants.RIGHT);

JLabel also has setHorizontalAlignment:

label.setHorizontalAlignment(SwingConstants.RIGHT);

This assumes the component takes up the whole width in the container.

Using Layout

A different approach is to use the layout to actually align the component to the right, whilst ensuring they do not take the whole width. Here is an example with BoxLayout:

    Box box = Box.createVerticalBox();
    JLabel label1 = new JLabel("test1, the beginning");
    label1.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label1);

    JLabel label2 = new JLabel("test2, some more");
    label2.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label2);

    JLabel label3 = new JLabel("test3");
    label3.setAlignmentX(Component.RIGHT_ALIGNMENT);
    box.add(label3);


    add(box);

<button style="position: absolute; left: 20%; right: 20%; bottom: 5%;"> Button </button>

If you want to use jQuery, the .load() function is the correct function you are after;

But you are missing the # from the div1 id selector in the example 2)

This should work:

$("#div1").load("file2.html");

This work for Checkbox too.

public class EnumToBoolConverter:IValueConverter
{
    private int val;
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

        int intParam = (int)parameter;
        val = (int)value;

        return ((intParam & val) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        val ^= (int)parameter;
        return Enum.Parse(targetType, val.ToString());

I made a new way without having a background drawable is that make it have CardView as parent and give it a app:cardCornerRadius="20dp" and then add this in the java class dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

It's another way to make it .

This is more of an important comment. Sharing references of sytanx that is acceptable out of the box. For hack solutions look at other answers.

Per Apple's docs, Action Method Definitions have to be either one of these three. Anything else is unaccepted.

@IBAction func doSomething()
@IBAction func doSomething(sender: UIButton)
@IBAction func doSomething(sender: UIButton, forEvent event: UIEvent)

The accepted answer is great, but if you need to interact programmatically with PostgreSQL version maybe it's better to do:

SELECT current_setting('server_version_num'); -- Returns 90603 (9.6.3)
-- Or using SHOW command:
SHOW server_version_num; -- Returns 90603 too

It will return server version as an integer. This is how server version is tested in PostgreSQL source, e.g.:

/*
 * This is a C code from pg_dump source.
 * It will do something if PostgreSQL remote version (server) is lower than 9.1.0
 */
if (fout->remoteVersion < 90100)
    /*
     * Do something...
     */

Even I was facing a similar error. Try below 2 steps (the first of which has been recommended here already) - 1. Add the dependencies to your pom.xml

         <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.5</version>
        </dependency>

        <dependency>
            <groupId>javax.activation</groupId>
            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>

2. If that doesn't work, manually place the jar files in your .m2\repository\javax\<folder>\<version>\ directory.

This regular expression handles floats as well

import re
re_float = re.compile(r'\d*\.?\d+')

You could also add a group to the expression that catches your weight units.

re_banana = re.compile(r'(?P<number>\d*\.?\d+)\s?(?P<uni>[a-zA-Z]+)')

You can access the named groups like this re_banana.match("200 kgm").group('number').

I think this should help you getting started.

That depends on what you define as special characters, but try replaceAll(...):

String result = yourString.replaceAll("[-+.^:,]","");

Note that the ^ character must not be the first one in the list, since you'd then either have to escape it or it would mean "any but these characters".

Another note: the - character needs to be the first or last one on the list, otherwise you'd have to escape it or it would define a range ( e.g. :-, would mean "all characters in the range : to ,).

So, in order to keep consistency and not depend on character positioning, you might want to escape all those characters that have a special meaning in regular expressions (the following list is not complete, so be aware of other characters like (, {, $ etc.):

String result = yourString.replaceAll("[\\-\\+\\.\\^:,]","");

If you want to get rid of all punctuation and symbols, try this regex: \p{P}\p{S} (keep in mind that in Java strings you'd have to escape back slashes: "\\p{P}\\p{S}").

A third way could be something like this, if you can exactly define what should be left in your string:

String  result = yourString.replaceAll("[^\\w\\s]","");

This means: replace everything that is not a word character (a-z in any case, 0-9 or _) or whitespace.

Edit: please note that there are a couple of other patterns that might prove helpful. However, I can't explain them all, so have a look at the reference section of regular-expressions.info.

Here's less restrictive alternative to the "define allowed characters" approach, as suggested by Ray:

String  result = yourString.replaceAll("[^\\p{L}\\p{Z}]","");

The regex matches everything that is not a letter in any language and not a separator (whitespace, linebreak etc.). Note that you can't use [\P{L}\P{Z}] (upper case P means not having that property), since that would mean "everything that is not a letter or not whitespace", which almost matches everything, since letters are not whitespace and vice versa.

Additional information on Unicode

Some unicode characters seem to cause problems due to different possible ways to encode them (as a single code point or a combination of code points). Please refer to regular-expressions.info for more information.

The other answers mostly use the flags for setSystemUiVisibility() method in View. However, this API is deprecated since Android 11. Check my article about modifying the system UI visibility for more information. The article also explains how to handle the cutouts properly or how to listen to the visibility changes.

Here are code snippets for showing / hiding system bars with the new API as well as the deprecated one for backward compatibility:

/**
 * Hides the system bars and makes the Activity "fullscreen". If this should be the default
 * state it should be called from [Activity.onWindowFocusChanged] if hasFocus is true.
 * It is also recommended to take care of cutout areas. The default behavior is that the app shows
 * in the cutout area in portrait mode if not in fullscreen mode. This can cause "jumping" if the
 * user swipes a system bar to show it. It is recommended to set [WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER],
 * call [showBelowCutout] from [Activity.onCreate]
 * (see [Android Developers article about cutouts](https://developer.android.com/guide/topics/display-cutout#never_render_content_in_the_display_cutout_area)).

You can use table proc in database mysql:

mysql> SELECT body FROM mysql.proc
WHERE db = 'yourdb' AND name = 'procedurename' ;

Note that you must have a grant for select to mysql.proc:

mysql> GRANT SELECT ON mysql.proc TO 'youruser'@'yourhost' IDENTIFIED BY 'yourpass' ;

if you already deployed the code or can't change any configuration, you could remove all temp files from wsdl:

rm /tmp/wsdl-*

you are better off with a decompiler like redgates .net reflector or jetbrains resharper decompiler. there are open source ones also like

As a supplement of the answer of Michael Parker, you can make getData accept a callback function to active the setState update the data:

componentWillMount : function () {
    var data = this.getData(()=>this.setState({data : data}));
},

Here's another way that might be faster, in terms of compute time, than iterating. Not sure. The idea is to convert the array to a string, truncate it, and get the size of the new array.

For example, to find the index of 'd':

arr=(a b c d)    
temp=`echo ${arr[@]}`
temp=( ${temp%%d*} )
index=${#temp[@]}

You could turn this into a function like:

get-index() {

    Item=$1
    Array="$2[@]"

    ArgArray=( ${!Array} )
    NewArray=( ${!Array%%${Item}*} )

    Index=${#NewArray[@]}

    [[ ${#ArgArray[@]} == ${#NewArray[@]} ]] && echo -1 || echo $Index

}

You could then call:

get-index d arr

and it would echo back 3, which would be assignable with:

index=`get-index d arr`

Since it is a numeric operation, we should be converting it to numeric form first. This operation cannot take place if the data is in factor data type.
Check the data type of the columns using str().

min(as.numeric(data[,2]))

Query below should help you achieve what you want.

select scountry, headofstate from data 
where data.scountry like 'a%'and ttlppl>=100000

You need to escape quotes with double backslashes.

This fails (produced by PHP's json_encode):

<script>
  var jsonString = '[{"key":"my \"value\" "}]';
  var parsedJson = JSON.parse(jsonString);
</script>

This works:

<script>
  var jsonString = '[{"key":"my \\"value\\" "}]';
  var parsedJson = JSON.parse(jsonString);
</script>

Why not try fadeOut?

$(document).ready(function() {_x000D_
  $('#plsme').fadeOut(5000); // 5 seconds x 1000 milisec = 5000 milisec_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<div id='plsme'>Loading... Please Wait</div>

fadeOut (Javascript Pure):

How to make fadeOut effect with pure JavaScript

Just simple as this code:

box-shadow: 0px 0px 2px 2px black; /*any color you want*/

$('.update-cart').click(function(e) {
    updateCartWidget();
    e.stopPropagation();
    e.preventDefault();
});

$('.update-cart').click(function() {
    updateCartWidget();
    return false;
});

The following methods achieve the exact same thing.

 <div *ngFor="let item of list;trackBy: trackByFunc" >
   {{item.value}}
 </div>

In your ts file

 trackByFunc(index, item){
    return item ? item.id : undefined;
  }

Just set the opacity for the inner table. You can do inline CSS if you want it just for a specific table element, so it doesn't apply to the entire table.

After 3 hours of searching and investigation.

I had problems with it because we have two members in team (using GitHub source control), because we didn't restrict files for packages for sending to remote repository, one of team members was send packages to server and i have pull that changes to my local.

After that i had same problem as PO, also i wasn't be able to publish my API project to server.

At the and I have just used

Update-Package -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that you have used in your solution. (For every project)

Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -ProjectName 'NameOfProject' -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that are in relation with project that you specified after "-ProjectName". And i think that this is better because i had wait for half a hour to reinstall all packages in solution.

For this many thanks to Rodolpho Brock.

Also, I would recommend you that when you pull changes from remote server, to press "Restore packages" button that will be shown by Visual studio.

I have been trying to think of a good convention to use when placing text next to components on different lines, and found a couple good options:

<p>
    Hello {
        <span>World</span>
    }!
</p>

or

<p>
    Hello {}
    <span>World</span>
    {} again!
</p>

Each of these produces clean html without additional   or other extraneous markup. It creates fewer text nodes than using {' '}, and allows using of html entities where {' hello & goodbye '} does not.

$('button').toggle(
function() {
    $('#B').css('left', '0')
}, function() {
    $('#B').css('left', '200px')
})

An alternate way would be to add a method to the Array prototype:

 Array.prototype.random = function (length) {
       return this[Math.floor((Math.random()*length))];
 }

 var teams = ['patriots', 'colts', 'jets', 'texans', 'ravens', 'broncos']
 var chosen_team = teams.random(teams.length)
 alert(chosen_team)

Yes, it’s frustrating—sometimes type and other programs print gibberish, and sometimes they do not.

First of all, Unicode characters will only display if the current console font contains the characters. So use a TrueType font like Lucida Console instead of the default Raster Font.

But if the console font doesn’t contain the character you’re trying to display, you’ll see question marks instead of gibberish. When you get gibberish, there’s more going on than just font settings.

When programs use standard C-library I/O functions like printf, the program’s output encoding must match the console’s output encoding, or you will get gibberish. chcp shows and sets the current codepage. All output using standard C-library I/O functions is treated as if it is in the codepage displayed by chcp.

Matching the program’s output encoding with the console’s output encoding can be accomplished in two different ways:

• A program can get the console’s current codepage using chcp or GetConsoleOutputCP, and configure itself to output in that encoding, or

• You or a program can set the console’s current codepage using chcp or SetConsoleOutputCP to match the default output encoding of the program.

However, programs that use Win32 APIs can write UTF-16LE strings directly to the console with WriteConsoleW. This is the only way to get correct output without setting codepages. And even when using that function, if a string is not in the UTF-16LE encoding to begin with, a Win32 program must pass the correct codepage to MultiByteToWideChar. Also, WriteConsoleW will not work if the program’s output is redirected; more fiddling is needed in that case.

type works some of the time because it checks the start of each file for a UTF-16LE Byte Order Mark (BOM), i.e. the bytes 0xFF 0xFE. If it finds such a mark, it displays the Unicode characters in the file using WriteConsoleW regardless of the current codepage. But when typeing any file without a UTF-16LE BOM, or for using non-ASCII characters with any command that doesn’t call WriteConsoleW—you will need to set the console codepage and program output encoding to match each other.

How can we find this out?

Here’s a test file containing Unicode characters:

ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

Here’s a Java program to print out the test file in a bunch of different Unicode encodings. It could be in any programming language; it only prints ASCII characters or encoded bytes to stdout.

import java.io.*;

public class Foo {

    private static final String BOM = "\ufeff";
    private static final String TEST_STRING
        = "ASCII     abcde xyz\n"
        + "German    äöü ÄÖÜ ß\n"
        + "Polish    aezznl\n"
        + "Russian   ??????? ???\n"
        + "CJK       ??\n";

    public static void main(String[] args)
        throws Exception
    {
        String[] encodings = new String[] {
            "UTF-8", "UTF-16LE", "UTF-16BE", "UTF-32LE", "UTF-32BE" };

        for (String encoding: encodings) {
            System.out.println("== " + encoding);

            for (boolean writeBom: new Boolean[] {false, true}) {
                System.out.println(writeBom ? "= bom" : "= no bom");

                String output = (writeBom ? BOM : "") + TEST_STRING;
                byte[] bytes = output.getBytes(encoding);
                System.out.write(bytes);
                FileOutputStream out = new FileOutputStream("uc-test-"
                    + encoding + (writeBom ? "-bom.txt" : "-nobom.txt"));
                out.write(bytes);
                out.close();
            }
        }
    }
}

The output in the default codepage? Total garbage!

However, what if we type the files that got saved? They contain the exact same bytes that were printed to the console.

The only thing that works is UTF-16LE file, with a BOM, printed to the console via type.

If we use anything other than type to print the file, we get garbage:

Z:\andrew\projects\sx\1259084>copy uc-test-UTF-16LE-bom.txt CON
 ¦A S C I I           a b c d e   x y z

 C J K               `O}Y
         1 file(s) copied.

From the fact that copy CON does not display Unicode correctly, we can conclude that the type command has logic to detect a UTF-16LE BOM at the start of the file, and use special Windows APIs to print it.

We can see this by opening cmd.exe in a debugger when it goes to type out a file:

After type opens a file, it checks for a BOM of 0xFEFF—i.e., the bytes 0xFF 0xFE in little-endian—and if there is such a BOM, type sets an internal fOutputUnicode flag. This flag is checked later to decide whether to call WriteConsoleW.

But that’s the only way to get type to output Unicode, and only for files that have BOMs and are in UTF-16LE. For all other files, and for programs that don’t have special code to handle console output, your files will be interpreted according to the current codepage, and will likely show up as gibberish.

You can emulate how type outputs Unicode to the console in your own programs like so:

#include <stdio.h>
#define UNICODE
#include <windows.h>

static LPCSTR lpcsTest =
    "ASCII     abcde xyz\n"
    "German    äöü ÄÖÜ ß\n"
    "Polish    aezznl\n"
    "Russian   ??????? ???\n"
    "CJK       ??\n";

int main() {
    int n;
    wchar_t buf[1024];

    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    n = MultiByteToWideChar(CP_UTF8, 0,
            lpcsTest, strlen(lpcsTest),
            buf, sizeof(buf));

    WriteConsole(hConsole, buf, n, &n, NULL);

    return 0;
}

This program works for printing Unicode on the Windows console using the default codepage.

For the sample Java program, we can get a little bit of correct output by setting the codepage manually, though the output gets messed up in weird ways:

Z:\andrew\projects\sx\1259084>chcp 65001
Active code page: 65001

Z:\andrew\projects\sx\1259084>java Foo
== UTF-8
= no bom
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl

CJK       ??

?
?
== UTF-16LE

A S C I I           a b c d e   x y z
…

However, a C program that sets a Unicode UTF-8 codepage:

#include <stdio.h>
#include <windows.h>

int main() {
    int c, n;
    UINT oldCodePage;
    char buf[1024];

    oldCodePage = GetConsoleOutputCP();
    if (!SetConsoleOutputCP(65001)) {
        printf("error\n");
    }

    freopen("uc-test-UTF-8-nobom.txt", "rb", stdin);
    n = fread(buf, sizeof(buf[0]), sizeof(buf), stdin);
    fwrite(buf, sizeof(buf[0]), n, stdout);

    SetConsoleOutputCP(oldCodePage);

    return 0;
}

does have correct output:

Z:\andrew\projects\sx\1259084>.\test
ASCII     abcde xyz
German    äöü ÄÖÜ ß
Polish    aezznl
Russian   ??????? ???
CJK       ??

The moral of the story?

• type can print UTF-16LE files with a BOM regardless of your current codepage
• Win32 programs can be programmed to output Unicode to the console, using WriteConsoleW.
• Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
• For everything else you will have to mess around with chcp, and will probably still get weird output.

The answer to this question is, perhaps surprisingly, never, or more realistically, only when you are forced to for interoperability with legacy code. This is the recommendation in Effective Java, 3rd Edition by Joshua Bloch:

There is no reason to use Java serialization in any new system you write

Oracle's chief architect, Mark Reinhold, is on record as saying removing the current Java serialization mechanism is a long-term goal.

Why Java serialization is flawed

Java provides as part of the language a serialization scheme you can opt in to, by using the Serializable interface. This scheme however has several intractable flaws and should be treated as a failed experiment by the Java language designers.

• It fundamentally pretends that one can talk about the serialized form of an object. But there are infinitely many serialization schemes, resulting in infinitely many serialized forms. By imposing one scheme, without any way of changing the scheme, applications can not use a scheme most appropriate for them.
• It is implemented as an additional means of constructing objects, which bypasses any precondition checks your constructors or factory methods perform. Unless tricky, error prone, and difficult to test extra deserialization code is written, your code probably has a gaping security weakness.
• Testing interoperability of different versions of the serialized form is very difficult.
• Handling of immutable objects is troublesome.

What to do instead

Instead, use a serialization scheme that you can explicitly control. Such as Protocol Buffers, JSON, XML, or your own custom scheme.

Grant usage/select to a single table

If you only grant CONNECT to a database, the user can connect but has no other privileges. You have to grant USAGE on namespaces (schemas) and SELECT on tables and views individually like so:

GRANT CONNECT ON DATABASE mydb TO xxx;
-- This assumes you're actually connected to mydb..
GRANT USAGE ON SCHEMA public TO xxx;
GRANT SELECT ON mytable TO xxx;

Multiple tables/views (PostgreSQL 9.0+)

In the latest versions of PostgreSQL, you can grant permissions on all tables/views/etc in the schema using a single command rather than having to type them one by one:

GRANT SELECT ON ALL TABLES IN SCHEMA public TO xxx;

This only affects tables that have already been created. More powerfully, you can automatically have default roles assigned to new objects in future:

ALTER DEFAULT PRIVILEGES IN SCHEMA public
   GRANT SELECT ON TABLES TO xxx;

Note that by default this will only affect objects (tables) created by the user that issued this command: although it can also be set on any role that the issuing user is a member of. However, you don't pick up default privileges for all roles you're a member of when creating new objects... so there's still some faffing around. If you adopt the approach that a database has an owning role, and schema changes are performed as that owning role, then you should assign default privileges to that owning role. IMHO this is all a bit confusing and you may need to experiment to come up with a functional workflow.

Multiple tables/views (PostgreSQL versions before 9.0)

To avoid errors in lengthy, multi-table changes, it is recommended to use the following 'automatic' process to generate the required GRANT SELECT to each table/view:

SELECT 'GRANT SELECT ON ' || relname || ' TO xxx;'
FROM pg_class JOIN pg_namespace ON pg_namespace.oid = pg_class.relnamespace
WHERE nspname = 'public' AND relkind IN ('r', 'v', 'S');

This should output the relevant GRANT commands to GRANT SELECT on all tables, views, and sequences in public, for copy-n-paste love. Naturally, this will only be applied to tables that have already been created.

PhantomJS recently dropped Python support altogether. However, PhantomJS now embeds Ghost Driver.

A new project has since stepped up to fill the void: ghost.py. You probably want to use that instead:

from ghost import Ghost
ghost = Ghost()

with ghost.start() as session:
    page, extra_resources = ghost.open("http://jeanphi.me")
    assert page.http_status==200 and 'jeanphix' in ghost.content

So as I understand it, you need to pull out successive pairs of hex digits, then decode that 2-digit hex number and take the corresponding char:

String s = "...";
StringBuilder sb = new StringBuilder(s.length() / 2);
for (int i = 0; i < s.length(); i+=2) {
    String hex = "" + s.charAt(i) + s.charAt(i+1);
    int ival = Integer.parseInt(hex, 16);
    sb.append((char) ival);
}
String string = sb.toString();

You can optimize your code by calling GetProperties only once per type:

public static string ToStringNullSafe(this object obj)
{
    return obj != null ? obj.ToString() : String.Empty;
}
public static bool Compare<T>(T a, T b, params string[] ignore)
{
    var aProps = a.GetType().GetProperties();
    var bProps = b.GetType().GetProperties();
    int count = aProps.Count();
    string aa, bb;
    for (int i = 0; i < count; i++)
    {
        aa = aProps[i].GetValue(a, null).ToStringNullSafe();
        bb = bProps[i].GetValue(b, null).ToStringNullSafe();
        if (aa != bb && ignore.Where(x => x == aProps[i].Name).Count() == 0)
        {
            return false;
        }
    }
    return true;
}

I have several projects in a solution. For some of the projects, I previously added the references manually. When I used NuGet to update the WebAPI package, those references were not updated automatically.

I found out that I can either manually update those reference so they point to the v5 DLL inside the Packages folder of my solution or do the following.

1. Go to the "Manage NuGet Packages"
2. Select the Installed Package "Microsoft ASP.NET Web API 2.1"
3. Click Manage and check the projects that I manually added before.

Give the #under a negative z-index, e.g. -1

This happens because the z-index property is ignored in position: static;, which happens to be the default value; so in the CSS code you wrote, z-index is 1 for both elements no matter how high you set it in #over.

By giving #under a negative value, it will be behind any z-index: 1; element, i.e. #over.

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

Only for windows I have fixed the mysql startup issue by following below steps

Steps:

1. Open CMD and copy paste the command netstat -ano | findstr 3306 If you get any result for command then the Port 3306 is active

2. Now we want to kill the active port(3306), so now open powershell and paste the command Stop-Process -Id (Get-NetTCPConnection -LocalPort 3306).OwningProcess -Force

Where 3306 is active port. Now port will be inactive

Start Mysql service from Xampp which will work fine now

Note: This works only if the port 3306 is in active state. If you didn't get any result from step 1 this method is not applicable. There could be some other errors

For other ports change 3306 to "Required port"

Ways to open CMD and Powershell

1. For CMD-> search for cmd from start menu
2. For Powershell-> search for powershell from start menu

You might want indexOf

if (code.indexOf("ST1") >= 0) { ... }
else if (code.indexOf("ST2") >= 0) { ... }

It checks if contains is anywhere in the string variable code. This requires code to be a string. If you want this solution to be case-insensitive you have to change the case to all the same with either String.toLowerCase() or String.toUpperCase().

You could also work with a switch statement like

switch (true) {
    case (code.indexOf('ST1') >= 0):
        document.write('code contains "ST1"');
        break;
    case (code.indexOf('ST2') >= 0):
        document.write('code contains "ST2"');        
        break;        
    case (code.indexOf('ST3') >= 0):
        document.write('code contains "ST3"');
        break;        
    }?

There is no such thing: I recommend to write it for yourself and use it whenever you need.

If you know how far back, you can try something like:

# Current branch vs. parent
git diff HEAD^ HEAD

# Current branch, diff between commits 2 and 3 times back
git diff HEAD~3 HEAD~2

Prior commits work something like this:

# Parent of HEAD
git show HEAD^1

# Grandparent
git show HEAD^2

There are a lot of ways you can specify commits:

# Great grandparent
git show HEAD~3

See this page for details.

You can get the DOM element, and set the disabled property directly.

$(".shownextrow").click(function() { 
  $(this).closest("tr").next().show()
          .find('.longboxsmall').hide()[0].disabled = 'disabled';
});

or if there's more than one, you can use each() to set all of them:

$(".shownextrow").click(function() { 
  $(this).closest("tr").next().show()
          .find('.longboxsmall').each(function() {
               this.style.display = 'none';
               this.disabled = 'disabled';
          });
});

Ensure your encoding is correct for all of your files, this can sometimes happen if you have the encoding wrong for your file or the wrong encoding in your XML header.

So, if I have the following NewFile.xml:

<?xml version="1.0" encoding="UTF-16"?>
<bar foo="foiré" />

And the eclipse encoding is UTF-8:

The encoding of your file, the defined encoding in Eclipse (through Properties->Resource) and the declared encoding in the XML document all need to agree.

The validator is attempting to read the file, expecting <?xml ... but because the encoding is different from that expected, it's not finding it. Hence the error: Content is not allowed in prolog. The prolog is the bit before the <?xml declaration.

EDIT: Sorry, didn't realise that the .xml files were generated and actually contain javascript.

When you suspend the validators, the error messages that you've generated don't go away. To get them to go away, you have to manually delete them.

1. Suspend the validators
2. Click on the 'Content is not allowed in prolog' message, right click and delete. You can select multiple ones, or all of them.
3. Do a Project->Clean. The messages should not come back.

I think that because you've suspended the validators, Eclipse doesn't realise it has to delete the old error messages which came from the validators.

The most simplest tool comes with glibc and is called getconf:

$ getconf _NPROCESSORS_ONLN

I had a same issue. It was working fine on the local machine but it had issues on the server. I have changed the SMTP setting. It works fine for me.

If you're using GoDaddy Plesk Hosting, use the following SMTP details.

Host = relay-hosting.secureserver.net
Port = 25 

def get_Value(dic,value):
    for name in dic:
        if dic[name] == value:
            del dic[name]
            return name

javax.servlet is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).

You could use the Java EE SDK for example.

Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar).

For InnoDB, the following seems to work: create the new empty database, then rename each table in turn into the new database:

RENAME TABLE old_db.table TO new_db.table;

You will need to adjust the permissions after that.

For scripting in a shell, you can use either of the following:

mysql -u username -ppassword old_db -sNe 'show tables' | while read table; \ 
    do mysql -u username -ppassword -sNe "rename table old_db.$table to new_db.$table"; done

OR

for table in `mysql -u root -ppassword -s -N -e "use old_db;show tables from old_db;"`; do mysql -u root -ppassword -s -N -e "use old_db;rename table old_db.$table to new_db.$table;"; done;

Notes:

• There is no space between the option -p and the password. If your database has no password, remove the -u username -ppassword part.

• If some table has a trigger, it cannot be moved to another database using above method (will result Trigger in wrong schema error). If that is the case, use a traditional way to clone a database and then drop the old one:

  mysqldump old_db | mysql new_db

• If you have stored procedures, you can copy them afterwards:

  mysqldump -R old_db | mysql new_db

For mysql8 and python 3.7 on windows, I find previous solutions seems not work for me.

Here is what worked for me:

pip install wheel

pip install mysqlclient-1.4.2-cp37-cp37m-win_amd64.whl

python -m pip install mysql-connector-python

python -m pip install SQLAlchemy

What's wrong with XOR encryption?

https://crypto.stackexchange.com/questions/56281/breaking-a-xor-cipher-of-known-key-length

https://github.com/hellman/xortool

As has been mentioned the PyCrypto library contains a suite of ciphers. The XOR "cipher" can be used to do the dirty work if you don't want to do it yourself:

from Crypto.Cipher import XOR
import base64

def encrypt(key, plaintext):
  cipher = XOR.new(key)
  return base64.b64encode(cipher.encrypt(plaintext))

def decrypt(key, ciphertext):
  cipher = XOR.new(key)
  return cipher.decrypt(base64.b64decode(ciphertext))

The cipher works as follows without having to pad the plaintext:

>>> encrypt('notsosecretkey', 'Attack at dawn!')
'LxsAEgwYRQIGRRAKEhdP'

>>> decrypt('notsosecretkey', encrypt('notsosecretkey', 'Attack at dawn!'))
'Attack at dawn!'

I had the same problem, and even with the solutions provided here it did not work. The checkboxes would simply not change, their Value would remain null. It took me ages to realize my dumbness:

Turns out, I called the form1.PopulateDataGridView(my data) on the Form derived class Form1 before I called form1.Show(). When I changed up the order, that is to call Show() first, and then read the data and fill in the checkboxes, the value did not stay null.

You can also delete cookies without using jquery.cookie plugin:

document.cookie = 'NAMEOFYOURCOOKIE' + '=; expires=Thu, 01-Jan-70 00:00:01 GMT;';

In JavaScript, an object is a standalone entity, with properties and type.

For fetching values from Object in form of array: Object.values(obj) // obj is object name that you used Result -> ["value1", "value2", "value3", "value4"]

For fetching keys from Object in form of array: Object.keys(obj) // obj is object name that you used Result -> ["key1", "key2", "key3", "key4"]

As both functions are returning array you can get the length of keys or value by using length property. For instance - Object.values(obj).length or Object.keys(obj).length
