let url = URL(string: "URLSTRING HERE")
let anyvar =  String(describing: url)

In Objective-C:

NSString *myString = myURL.absoluteString;

In Swift:

var myString = myURL.absoluteString

More info in the docs:

Configurations above didn't work for me. I tried a lot of combinations of keys, this one work fine:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>mydomain.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

If you are looking for a very very simple implementation. (This worked for me in Swift 2)

 let imageURL = NSURL(string: "https://farm2.staticflickr.com/1591/26078338233_d1466b7da2_m.jpg")
 let imagedData = NSData(contentsOfURL: imageURL!)!
 imageView?.image = UIImage(data: imagedData)

I implemented within a tableview with a custom cell that has only a image

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{

        let cell = tableView.dequeueReusableCellWithIdentifier("theCell", forIndexPath: indexPath) as! customTableViewCell

        let imageURL = NSURL(string: "https://farm2.staticflickr.com/1591/26078338233_d1466b7da2_m.jpg")

        let imagedData = NSData(contentsOfURL: imageURL!)!

        cell.imageView?.image = UIImage(data: imagedData)

        return cell

    }

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

For those in the future looking for a simple way to do this in Razor pages, use the following:

In .cshtml:

@Html.Raw(Html.Encode("<span>blah<span>"))

In .cshtml.cs:

string rawHtml = Html.Raw(Html.Encode("<span>blah<span>"));

<?php echo substr("abcabcabc", 0, -3); ?>

var object = { "a": 1, "b": 2};_x000D_
$.each(object, function(key, value){_x000D_
  console.log(key + ": " + object[key]);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

//output
a: 1
b: 2

Let's consider that you have input as "1,2,3,4".

That means the length of the input is 7. So now you write the size = 7/2 = 3.5. But as size is an int, it will be rounded off to 3. In short, you are losing 1 value.

If you rewrite the code as below it should work:

String input;
int length, count, size;
Scanner keyboard = new Scanner(System.in);
input = keyboard.next();
length = input.length();

String strarray[] = input.split(",");
int intarray[] = new int[strarray.length];

for (count = 0; count < intarray.length ; count++) {
    intarray[count] = Integer.parseInt(strarray[count]);
}

for (int s : intarray) {
    System.out.println(s);
}

I'm using display:block for thead and tbody. Because of that the width of the thead columns is different from the width of the tbody columns.

table {
    margin:0 auto; 
    border-collapse:collapse;
}
thead {
    background:#CCCCCC;
    display:block
}
tbody {
    height:10em;overflow-y:scroll;
    display:block
}

To fix this I use small jQuery code but it can be done in JavaScript only.

var colNumber=3 //number of table columns    

for (var i=0; i<colNumber; i++) {
  var thWidth=$("#myTable").find("th:eq("+i+")").width();
  var tdWidth=$("#myTable").find("td:eq("+i+")").width();      
  if (thWidth<tdWidth)                    
      $("#myTable").find("th:eq("+i+")").width(tdWidth);
  else
      $("#myTable").find("td:eq("+i+")").width(thWidth);           
}  

Here is my working demo: http://jsfiddle.net/gavroche/N7LEF/

The default output format (which originally comes from a program known as diff if you want to look for more info) is known as a “unified diff”. It contains essentially 4 different types of lines:

• context lines, which start with a single space,
• insertion lines that show a line that has been inserted, which start with a +,
• deletion lines, which start with a -, and
• metadata lines which describe higher level things like which file this is talking about, what options were used to generate the diff, whether the file changed its permissions, etc.

I advise that you practice reading diffs between two versions of a file where you know exactly what you changed. Like that you'll recognize just what is going on when you see it.

Change the definition of multiply to take additional unknown arguments:

multiply <- function(a, b, ...) {
  # Original code
}

You can add a specific url to each point, e.g.:

var points = [
    ['name1', 59.9362384705039, 30.19232525792222, 12, 'www.google.com'],
    ['name2', 59.941412822085645, 30.263564729357767, 11, 'www.amazon.com'],
    ['name3', 59.939177197629455, 30.273554411974955, 10, 'www.stackoverflow.com']
];

Add the url to the marker values in the for-loop:

var marker = new google.maps.Marker({
    ...
    zIndex: place[3],
    url: place[4]
});

Then you can add just before to the end of your for-loop:

google.maps.event.addListener(marker, 'click', function() {
    window.location.href = this.url;
});

Also see this example.

• Short answer: for "can't find dependent library" error, check your $PATH (corresponds to bullet point #3 below)
• Long answer:
  1. Pure java world: jvm uses "Classpath" to find class files
  2. JNI world (java/native boundary): jvm uses "java.library.path" (which defaults to $PATH) to find dlls
  3. pure native world: native code uses $PATH to load other dlls

With rails >= 3.0, you can simply use the placeholder option.

f.text_field :attr, placeholder: "placeholder text"

You can perform your housekeeping in a separate script which can be cronned to run daily. Something like this:

find /path/to/logs -type f -mtime +7 -exec rm -f {} \;

Because async functions are promises, you can create a static function on your class which executes an async function which returns the instance of the class:

class Yql {
  constructor () {
    // Set up your class
  }

  static init () {
    return (async function () {
      let yql = new Yql()
      // Do async stuff
      await yql.build()
      // Return instance
      return yql
    }())
  }  

  async build () {
    // Do stuff with await if needed
  }
}

async function yql () {
  // Do this instead of "new Yql()"
  let yql = await Yql.init()
  // Do stuff with yql instance
}

yql()

Call with let yql = await Yql.init() from an async function.

Using CodeIgniter OAuth2/0.4.0 sparks,

in Auth.php file,

$user = $provider->get_user_info($token);

$friends = $provider->get_friends_list($token);
print_r($friends);

and in Facebook.php file under Provider, add the following function,

    public function get_friends_list(OAuth2_Token_Access $token)
    {
            $url = 'https://graph.facebook.com/me/friends?'.http_build_query(array(
                    'access_token' => $token->access_token,
            ));
            $friends = json_decode(file_get_contents($url),TRUE);

            return $friends;
    }

prints the facebenter code hereook friends.

public static T DeserializeFromXml<T>(string xml)
{
    T result;
    XmlSerializerFactory serializerFactory = new XmlSerializerFactory();
    XmlSerializer serializer =serializerFactory.CreateSerializer(typeof(T));

    using (StringReader sr3 = new StringReader(xml))
    {
        XmlReaderSettings settings = new XmlReaderSettings()
        {
            CheckCharacters = false // default value is true;
        };

        using (XmlReader xr3 = XmlTextReader.Create(sr3, settings))
        {
            result = (T)serializer.Deserialize(xr3);
        }
    }

    return result;
}

Yeah, you can call other method before of the call base or this!

public class MyException : Exception
{
    public MyException(int number) : base(ConvertToString(number)) 
    {
    }

    private static string ConvertToString(int number) 
    { 
      return number.toString()
    }

}

Google Closure has a nice function for this... goog.object.getCount(obj)

look at goog.Object Documentation

Update:

_.find would be better as it breaks out of the loop when the element is found:

var searchArr = [{id:1,text:"foo"},{id:2,text:"bar"}];
var count = 0;
var filteredEl = _.find(searchArr,function(arrEl){ 
              count = count +1;
              if(arrEl.id === 1 ){
                  return arrEl;
              }
            });

console.log(filteredEl);
//since we are searching the first element in the array, the count will be one
console.log(count);
//output: filteredEl : {id:1,text:"foo"} , count: 1

** Old **

If you want to conditionally break out of a loop, use _.filter api instead of _.each. Here is a code snippet

var searchArr = [{id:1,text:"foo"},{id:2,text:"bar"}];
var filteredEl = _.filter(searchArr,function(arrEl){ 
                  if(arrEl.id === 1 ){
                      return arrEl;
                  }
                });
console.log(filteredEl);
//output: {id:1,text:"foo"}

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

SELECT * FROM user_cons_columns WHERE table_name = 'table_name';

Login MySql from windows cmd using existing user:

mysql -u username -p
Enter password:****

Then run the following command:

mysql> SELECT * FROM mysql.user;

After that copy encrypted md5 password for corresponding user and there are several online password decrypted application available in web. Using this decrypt password and use this for login in next time. or update user password using flowing command:

mysql> UPDATE mysql.user SET Password=PASSWORD('[password]') WHERE User='[username]';

Then login using the new password and user.

Alternatively, you may use FillDown

Range("M3") = "=G3&"",""&L3": Range("M3:M" & LastRow).FillDown

Best one

String str_date=month+"-"+day+"-"+yr;
DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy");
Date date = (Date)formatter.parse(str_date); 
long output=date.getTime()/1000L;
String str=Long.toString(output);
long timestamp = Long.parseLong(str) * 1000;

Save yourself some troubleshooting time and log your require call, like so:

console.log(require('dotenv').config())

You should see an error with more detailed info on the problem.

In Intent, you can directly put Uri. You don't need to convert the Uri to string and convert back again to Uri.

Look at this simple approach.

// put uri to intent 
intent.setData(imageUri);

And to get Uri back from intent:

// Get Uri from Intent
Uri imageUri=getIntent().getData();

This Depends on what version of python is installed on you system. See below.

If You have Python 2.* version you have to run this command

python gameover.py

But if you have Python 3.* version you have to run this command

python3 gameover.py

Because for MAC with Python version 3.* you will get command not found error

if you run "python gameover.py"

This page may give you some hints - http://www.zanthan.com/itymbi/archives/000337.html

There may be a subtle bug in the body of that method that javac fails to spot. Difficult to diagnose unless you post the whole method here.

You could start by declaring as many variables as possible as final... that would have caught the bug mentioned on the zanthan site, and is often a good practice anyways.

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

This makes sure you are getting the latest version from of the css or js file from the server.

And later you can append "?v=2" if you have a newer version and "?v=3", "?v=4" and so on.

Note that you can use any querystring, 'v' is not a must for example:

"?blah=1" will work as well.

And

"?xyz=1002" will work.

And this is a common technique because browsers are now caching js and css files better and longer.

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

Toast, AlertDialogs needs to run on UI thread, you can use Asynctask to use them properly in android development.but some cases we need to customize the time outs, so we use Threads, but in threads we cannot use Toast,Alertdialogs like we using in AsyncTask.So we need separate Handler for popup those.

public void onSigned() {
    Thread thread = new Thread(){
        @Override
        public void run() {
            try{
                sleep(3000);
                Message message = new Message();
                message.what = 2;
                handler.sendMessage(message);
            } catch (Exception e){
                e.printStackTrace();
            }
        }
    };
    thread.start();
}

in Above example i want to sleep my thread in 3sec and after i want to show a Toast message,for that in your mainthread implement handler.

handler = new Handler() {
       public void handleMessage(Message msg) {
           switch(msg.what){
              case 1:
              Toast.makeText(getActivity(),"cool",Toast.LENGTH_SHORT).show();
              break;
           }
           super.handleMessage(msg);
       }
};

I used switch case here, because if you need to show different message in same way, you can use switch case within Handler class...hope this will help you

Overall, the conventions are “think like you're just delivering web pages”.

For a PUT, I'd return the same view that you'd get if you did a GET immediately after; that would result in a 200 (well, assuming the rendering succeeds of course). For a POST, I'd do a redirect to the resource created (assuming you're doing a creation operation; if not, just return the results); the code for a successful create is a 201, which is really the only HTTP code for a redirect that isn't in the 300 range.

I've never been happy about what a DELETE should return (my code currently produces an HTTP 204 and an empty body in this case).

Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want

x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)

WORD.C <- function(WORDS){
  require(wordcloud)

  L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))

  # Takes a dataframe and the text you want to display
  FUN <- function(X, text){
    windows() 
    wordcloud(X[, 1], X[, 2], min.freq=1)
    mtext(text, 3, padj=-4.5, col="red")  #what I'm trying that isn't working
  }

  # Now creates the sequence 1,...,length(L2)
  # Loops over that and then create an anonymous function
  # to send in the information you want to use.
  lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})

  # Since you asked about loops
  # you could use i in seq_along(L2) 
  # instead of 1:length(L2) if you wanted to
  #for(i in 1:length(L2)){
  #  FUN(L2[[i]], names(L2)[i])
  #}
}

WORD.C(list.xy)

In response to your first question: Yes, you have to run a server app to send the messages, as well as a client app to receive them.

In response to your second question: Yes, every application needs its own API key. This key is for your server app, not the client.

To reference the contents of the single array containing one or more objects i.e. everything in the brackets of something like this {messages: [{"a":1,"b":2}] } ,just add [0] to the query to get the first array element

e.g. messages[0] will reference the object {"a":1,"b":2} as opposed to just messages which would reference the entire array [{"a":1,"b":2}]

from there you can work with the result as typical object and use Object.keys for example to get "a" and "b".

James Sulak asked,

Is there any way I can make Python automatically print a ? instead of failing in this situation?

Other solutions recommend we attempt to modify the Windows environment or replace Python's print() function. The answer below comes closer to fulfilling Sulak's request.

Under Windows 7, Python 3.5 can be made to print Unicode without throwing a UnicodeEncodeError as follows:

    In place of:    print(text)
    substitute:     print(str(text).encode('utf-8'))

Instead of throwing an exception, Python now displays unprintable Unicode characters as \xNN hex codes, e.g.:

  Halmalo n\xe2\x80\x99\xc3\xa9tait plus qu\xe2\x80\x99un point noir

Instead of

  Halmalo n’était plus qu’un point noir

Granted, the latter is preferable ceteris paribus, but otherwise the former is completely accurate for diagnostic messages. Because it displays Unicode as literal byte values the former may also assist in diagnosing encode/decode problems.

Note: The str() call above is needed because otherwise encode() causes Python to reject a Unicode character as a tuple of numbers.

You can always fall back to the good old WinAPI calls, although the amount of work involved is non-trivial. There is no requirement that .NET services be installed via a .NET-aware mechanism.

To install:

• Open the service manager via OpenSCManager.
• Call CreateService to register the service.
• Optionally call ChangeServiceConfig2 to set a description.
• Close the service and service manager handles with CloseServiceHandle.

To uninstall:

• Open the service manager via OpenSCManager.
• Open the service using OpenService.
• Delete the service by calling DeleteService on the handle returned by OpenService.
• Close the service and service manager handles with CloseServiceHandle.

The main reason I prefer this over using the ServiceInstaller/ServiceProcessInstaller is that you can register the service with your own custom command line arguments. For example, you might register it as "MyApp.exe -service", then if the user runs your app without any arguments you could offer them a UI to install/remove the service.

Running Reflector on ServiceInstaller can fill in the details missing from this brief explanation.

P.S. Clearly this won't have "the same effect as calling: InstallUtil MyService.exe" - in particular, you won't be able to uninstall using InstallUtil. But it seems that perhaps this wasn't an actual stringent requirement for you.

As @Houcem Berrayana say

If you would like to use n>24 then you can use the code like:

Date dateBefore = new Date((d.getTime() - n * 24 * 3600 * 1000) - n * 24 * 3600 * 1000); 

Suppose you want to find last 30 days date, then you'd use:

Date dateBefore = new Date((d.getTime() - 24 * 24 * 3600 * 1000) - 6 * 24 * 3600 * 1000); 

To plot an equation that is not solved for a specific variable (like circle or hyperbola):

import numpy as np  
import matplotlib.pyplot as plt  
plt.figure() # Create a new figure window
xlist = np.linspace(-2.0, 2.0, 100) # Create 1-D arrays for x,y dimensions
ylist = np.linspace(-2.0, 2.0, 100) 
X,Y = np.meshgrid(xlist, ylist) # Create 2-D grid xlist,ylist values
F = X**2 + Y**2 - 1  #  'Circle Equation
plt.contour(X, Y, F, [0], colors = 'k', linestyles = 'solid')
plt.show()

Just enable parsing of the autoexec.bat in the registry, using these instructions.

:: works only on windows vista and earlier 
Run REGEDT32.EXE.
Modify the following value within HKEY_CURRENT_USER: 

Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ParseAutoexec 

1 = autoexec.bat is parsed
0 = autoexec.bat is not parsed

If the goal is to be able to push to a GitHub repo whenever you want to, then in Windows under C:\Users\tiago\.ssh where the keys are stored (at least in my case), create a file named config and add the following in it

Host github.com
    HostName github.com
    User your_user_name
    IdentityFile ~/.ssh/your_file_name

Then simply open Git Bash and you'll be able to push without having to manually start the ssh-agent and adding the key.

I know this is an oldie but here is a quick way to hide the scroll bar with pure CSS.

Just add

::-webkit-scrollbar {display:none;}

To your id or class of the div you're using the scroll bar with.

Here is a helpful link Custom Scroll Bar in Webkit

I use below simple solution:

This is your workbook and sheet:

XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("YOUR Workshhet");

then add data to your sheet with columns and rows. Once done with adding data to sheet write following code to autoSizeColumn width.

for (int columnIndex = 0; columnIndex < 15; columnIndex++) {
                    sheet.autoSizeColumn(columnIndex);
                }

Here, instead 15, you add the number of columns in your sheet.

Hope someone helps this.

I found a space in one of the header (titles) on the Excel sheet. Once I removed the space before the name, it went smoothly.

Just use strftime :)

Something like that:

my_date = datetime.datetime(2013, 1, 7, 10, 31, 34, 243366, tzinfo=<UTC>)
print(my_date.strftime("%Y, %d %B"))

After edited your question to format timedelta, you could use:

def timedelta_tuple(timedelta_object):
   return timedelta_object.days, timedelta_object.seconds//3600, (timedelta_object.seconds//60)%60

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

I'd try inserting an 'r' in front of your path if I were you, to indicate that it's a raw string - and then you won't have to use forward slashes. For example:

os.system(r"C:\Documents and Settings\flow_model\flow.exe")

I'm a bit surprised nobody is using the backspace character. Here's one that uses it.

import sys
import time

secs = 1000

while True:
    time.sleep(1)  #wait for a full second to pass before assigning a second
    secs += 1  #acknowledge a second has passed

    sys.stdout.write(str(secs))

    for i in range(len(str(secs))):
        sys.stdout.write('\b')

Lets look at this code (jdk1.8)

@Test
    public void testArraySize() throws Exception {
        List<String> list = new ArrayList<>();
        list.add("ds");
        list.add("cx");
        list.add("cx");
        list.add("ww");
        list.add("ds");
        list.add("cx");
        list.add("cx");
        list.add("ww");
        list.add("ds");
        list.add("cx");
        list.add("last");
    }

1)Put break point on the line when "last" is inserted

2)Go to the add method of ArrayList You will see

ensureCapacityInternal(size + 1);  // Increments modCount!!
        elementData[size++] = e;

3) Go to ensureCapacityInternal method this method call ensureExplicitCapacity

4)

private void ensureExplicitCapacity(int minCapacity) {
        modCount++;

        // overflow-conscious code
        if (minCapacity - elementData.length > 0)
            grow(minCapacity);
    }
            return true;

In our example minCapacity is equal to 11 11-10 > 0 therefore You need grow method

5)

private void grow(int minCapacity) {
        // overflow-conscious code
        int oldCapacity = elementData.length;
        int newCapacity = oldCapacity + (oldCapacity >> 1);
        if (newCapacity - minCapacity < 0)
            newCapacity = minCapacity;
        if (newCapacity - MAX_ARRAY_SIZE > 0)
            newCapacity = hugeCapacity(minCapacity);
        // minCapacity is usually close to size, so this is a win:
        elementData = Arrays.copyOf(elementData, newCapacity);
    }

Lets describe each step:

1) oldCapacity = 10 because we didn't put this param when ArrayList was init ,therefore it will use default capacity(10)

2) int newCapacity = oldCapacity + (oldCapacity >> 1); Here newCapacity is equal to oldCapacity plus oldCapacity with right shift by one (oldCapacity is 10 this is the binary representation 00001010 moving one bit to right we will get 00000101 which is 5 in decimal therefore newCapacity is 10 + 5 = 15)

3)

if (newCapacity - minCapacity < 0)
                newCapacity = minCapacity;

For example your init capacity is 1, when you add the second element into arrayList newCapacity will be equal to 1(oldCapacity) + 0 (moved to right by one bit) = 1 In this case newCapacity is less than minCapacity and elementData(array object inside arrayList) can't hold new element therefore newCapacity is equal to minCapacity

4)

if (newCapacity - MAX_ARRAY_SIZE > 0)
            newCapacity = hugeCapacity(minCapacity);

Check if array size reach MAX_ARRAY_SIZE (which is Integer.MAX - 8) Why the maximum array size of ArrayList is Integer.MAX_VALUE - 8?

5) Finally it copy old values to the newArray with length 15

This is all you have to do:

In front.inc

global $name;
$name = 'james';

For Each row As DataGridViewRow In yourDGV.SelectedRows
    yourDGV.Rows.Remove(row)
Next

This will delete all rows that had been selected.

Should it be necessary to manually remove a service:

1. Run Regedit or regedt32.
2. Find the registry key entry for your service under the following key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
3. Delete the Registry Key

You will have to reboot before the list gets updated in services

On my Linux machine :

git config --system --get https.proxy (returns nothing)
git config --global --get https.proxy (returns nothing)

git config --system --get http.proxy (returns nothing)
git config --global --get http.proxy (returns nothing)

I found out my https_proxy and http_proxy are set, so I just unset them.

unset https_proxy
unset http_proxy

On my Windows machine :

set https_proxy=""
set http_proxy=""

Optionally use setx to set environment variables permanently on Windows and set system environment using "/m"

setx https_proxy=""
setx http_proxy=""

I run this command within a bash script, in particular to submit SGE jobs and batch process things:

/Path_to_matlab -nodisplay -nosplash -nodesktop < m_file.m

because you are just learning I suggest you practice converting a SELECT joins to UPDATE or DELETE joins. First I suggest you generate a SELECT statement joining these two tables:

SELECT *
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Then note that we have two table aliases a and b. Using these aliases you can easily generate UPDATE statement to update either table a or b. For table a you have an answer provided by JW. If you want to update b, the statement will be:

UPDATE  b
SET     b.marks = a.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Now, to convert the statement to a DELETE statement use the same approach. The statement below will delete from a only (leaving b intact) for those records that match by name:

DELETE a
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

You can use the SQL Fiddle created by JW as a playground

I think it's possible in Java 9:

animalMap.entrySet().stream()
                .forEach(
                        pair -> Optional.ofNullable(pair.getValue())
                                .ifPresentOrElse(v -> myMap.put(pair.getKey(), v), v -> myList.add(pair.getKey())))
                );

Need the ifPresentOrElse for it to work though. (I think a for loop looks better.)

Deleting .gradle as suggested by Suragch wasn't enough for me. Additionally, I had to perform a Build > Clean Project.

Note that, in order to see .gradle, you need to switch to the "Project" view in the navigator on the top left:

The -Wl,xxx option for gcc passes a comma-separated list of tokens as a space-separated list of arguments to the linker. So

gcc -Wl,aaa,bbb,ccc

eventually becomes a linker call

ld aaa bbb ccc

In your case, you want to say "ld -rpath .", so you pass this to gcc as -Wl,-rpath,. Alternatively, you can specify repeat instances of -Wl:

gcc -Wl,aaa -Wl,bbb -Wl,ccc

Note that there is no comma between aaa and the second -Wl.

Or, in your case, -Wl,-rpath -Wl,..

If your are looking for the value defined by applicationId in gradle, you can simply use

BuildConfig.APPLICATION_ID 

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

In MVC you should provide the View with all data, not let the View collect its own data so what you can do is to set the CSS class in your controller action.

ViewData["CssClass"] = "bold";

and pick out this value from your ViewData in your View

If start can't find what it's looking for, it does what you describe.

Since what you're doing should work, it's very likely you're leaving out some quotes (or putting extras in).

Joshua P Nixon's answer is correct but I had to set last modified date also. so here is the code.

var file = new File([blob], "file_name", {lastModified: 1534584790000});

1534584790000 is an unix timestamp for "GMT: Saturday, August 18, 2018 9:33:10 AM"

Python’s wonderful standard library to the rescue…

import codecs

reader = codecs.getreader("utf-8")
obj = json.load(reader(response))

Works with both py2 and py3.

Docs: Python 2, Python3

If you want to set custom content-type for formData item:

var img = {
    uri : 'file://opa.jpeg',
    name: 'opa.jpeg',
    type: 'image/jpeg'
};
var personInfo = {
    name : 'David',
    age: 16
};

var fdata = new FormData();
fdata.append('personInfo', {
    "string": JSON.stringify(personInfo), //This is how it works :)
    type: 'application/json'
});

fdata.append('image', {
    uri: img.uri,
    name: img.name,
    type: img.type
});

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

I am posting this answer to provide a script with explanations that covers three different scenarios of creating a local repo that has a local remote. You can run the entire script and it will create the test repos in your home folder (tested on windows git bash). The explanations are inside the script for easier saving to your personal notes, its very readable from, e.g. Visual Studio Code.

I would also like to thank Jack for linking to this answer where adelphus has good, detailed, hands on explanations on the topic.

This is my first post here so please advise what should be improved.

## SETUP LOCAL GIT REPO WITH A LOCAL REMOTE
# the main elements:
# - remote repo must be initialized with --bare parameter
# - local repo must be initialized
# - local repo must have at least one commit that properly initializes a branch(root of the commit tree)
# - local repo needs to have a remote
# - local repo branch must have an upstream branch on the remote

{ # the brackets are optional, they allow to copy paste into terminal and run entire thing without interruptions, run without them to see which cmd outputs what

cd ~
rm -rf ~/test_git_local_repo/

## Option A - clean slate - you have nothing yet

mkdir -p ~/test_git_local_repo/option_a ; cd ~/test_git_local_repo/option_a
git init --bare local_remote.git # first setup the local remote
git clone local_remote.git local_repo # creates a local repo in dir local_repo
cd ~/test_git_local_repo/option_a/local_repo
git remote -v show origin # see that git clone has configured the tracking
touch README.md ; git add . ; git commit -m "initial commit on master" # properly init master
git push origin master # now have a fully functional setup, -u not needed, git clone does this for you

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branches and their respective remote upstream branches with the initial commit
git remote -v show origin # see all branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote

## Option B - you already have a local git repo and you want to connect it to a local remote

mkdir -p ~/test_git_local_repo/option_b ; cd ~/test_git_local_repo/option_b
git init --bare local_remote.git # first setup the local remote

# simulate a pre-existing git local repo you want to connect with the local remote
mkdir local_repo ; cd local_repo
git init # if not yet a git repo
touch README.md ; git add . ; git commit -m "initial commit on master" # properly init master
git checkout -b develop ; touch fileB ; git add . ; git commit -m "add fileB on develop" # create develop and fake change

# connect with local remote
cd ~/test_git_local_repo/option_b/local_repo
git remote add origin ~/test_git_local_repo/option_b/local_remote.git
git remote -v show origin # at this point you can see that there is no the tracking configured (unlike with git clone), so you need to push with -u
git push -u origin master # -u to set upstream
git push -u origin develop # -u to set upstream; need to run this for every other branch you already have in the project

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branch(es) and its remote upstream with the initial commit
git remote -v show origin # see all remote branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote

## Option C - you already have a directory with some files and you want it to be a git repo with a local remote

mkdir -p ~/test_git_local_repo/option_c ; cd ~/test_git_local_repo/option_c
git init --bare local_remote.git # first setup the local remote

# simulate a pre-existing directory with some files
mkdir local_repo ; cd local_repo ; touch README.md fileB

# make a pre-existing directory a git repo and connect it with local remote
cd ~/test_git_local_repo/option_c/local_repo
git init
git add . ; git commit -m "inital commit on master" # properly init master
git remote add origin ~/test_git_local_repo/option_c/local_remote.git
git remote -v show origin # see there is no the tracking configured (unlike with git clone), so you need to push with -u
git push -u origin master # -u to set upstream

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branch and its remote upstream with the initial commit
git remote -v show origin # see all remote branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote
}

I've been verifying calls in the same manner - I believe it is the right way to do it.

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => mo.Id == 5 && mo.description == "test")
  ), Times.Once());

If your lambda expression becomes unwieldy, you could create a function that takes MyObject as input and outputs true/false...

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => MyObjectFunc(mo))
  ), Times.Once());

private bool MyObjectFunc(MyObject myObject)
{
  return myObject.Id == 5 && myObject.description == "test";
}

Also, be aware of a bug with Mock where the error message states that the method was called multiple times when it wasn't called at all. They might have fixed it by now - but if you see that message you might consider verifying that the method was actually called.

EDIT: Here is an example of calling verify multiple times for those scenarios where you want to verify that you call a function for each object in a list (for example).

foreach (var item in myList)
  mockRepository.Verify(mr => mr.Update(
    It.Is<MyObject>(i => i.Id == item.Id && i.LastUpdated == item.LastUpdated),
    Times.Once());

Same approach for setup...

foreach (var item in myList) {
  var stuff = ... // some result specific to the item
  this.mockRepository
    .Setup(mr => mr.GetStuff(item.itemId))
    .Returns(stuff);
}

So each time GetStuff is called for that itemId, it will return stuff specific to that item. Alternatively, you could use a function that takes itemId as input and returns stuff.

this.mockRepository
    .Setup(mr => mr.GetStuff(It.IsAny<int>()))
    .Returns((int id) => SomeFunctionThatReturnsStuff(id));

One other method I saw on a blog some time back (Phil Haack perhaps?) had setup returning from some kind of dequeue object - each time the function was called it would pull an item from a queue.

Swift 4:

DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(100)) {
   // Code
}

For the time .seconds(Int), .microseconds(Int) and .nanoseconds(Int) may also be used.

The argument of func is accepting double-pointer variable. Hope this helps...

#include <stdio.h>

int func(int **B){

}

int main(void){

    int *B[10];

    func(B);

    return 0;
}

If you want to open a specific browser (e.g. Chrome and Chromium) with command line options like full screen or kiosk mode and also want to be able to kill it later on, then this might work for you:

from threading import Timer
from time import sleep

import subprocess
import platform

# Hint 1: to enable F11 use --start-fullscreen instead of --kiosk, otherwise Alt+F4 to close the browser   
# Hint 2: fullscreen will only work if chrome is not already running

platform_browser = {
'Windows': r'"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk http://stackoverflow.com',
'Linux' : ['/usr/bin/chromium-browser', '--kiosk', 'http://stackoverflow.com']
}

browser = None
def open_browser():
    global browser

    platform_name = platform.system()

    if platform_name in  platform_browser:        
        browser = subprocess.Popen(platform_browser[platform_name])
    else:
        print(":-(")

Timer(1, open_browser).start() # delayed start, give e.g. your own web server time to launch

sleep(20) # start e.g. your python web server here instead

browser.kill()

The official docs say to use: wa.me. Don't use wa.me. I apologize for the length of these results, but it's been a rapidly-evolving issue....

https://api.whatsapp.com/send?text=YourShareTextHere
https://api.whatsapp.com/send?text=YourShareTextHere&phone=123

If you are interested in watching a project that keeps track of these URLs, then check us out!: https://github.com/bradvin/social-share-urls#telegramme

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

This problem is probably from your /etc/apt/sources.list as others mentioned but there is chance that the problem is with your hard disk. I solved the same issue by cleaning up some space.

When you don't have enough space on your hard disk, updating your machine won't occur until you delete some files.

If you're getting this error because of a new realm you created

In the URL that you are redirected to (you may have to look in Chrome dev tools for this URL), change the realm from master to the one you just created, and if you are not using https, then make sure the redirect_uri is also using http.

If you're getting this error because you're trying to setup Keycloak on a public facing domain (not localhost)

Step 1) Follow this documentation to setup a MySql database. You may also need to refer to the official documentation.

Step 2) Run the command update REALM set ssl_required = 'NONE' where id = 'master';

Note: At this point, you should technically be able to login, but version 4.0 of Keycloak is using https for the redirect uri even though we just turned off https support. Until Keycloak fixes this, we can get around this with a reverse proxy. A reverse proxy is something we will want to use anyhow to easily create SSL/TLS certificates without having to worry about Java keystores.

Note 2: Keycloak has since come out with their own proxy. I haven't tried this yet, but at this point, you might want to stop following my directions and check out (keycloak gatekeeper)[https://www.keycloak.org/downloads.html]. If you have trouble setting up the Keycloak Gatekeeper, I'll keep my instructions around for setting up a reverse proxy with Apache.

Step 3) Install Apache. We will use Apache as a reverse proxy (I tried NGINX, but NGINX had some limitations that got in the way). See yum installing Apache (CentOs 7), and apt-get install Apache (Ubuntu 16), or find instructions for your specific distro.

Step 4) Run Apache

• Use sudo systemctl start httpd (CentOs) or sudo systemctl start apache2 (Ubuntu)

• Use sudo systemctl status httpd (CentOs) or sudo systemctl status apache2 (Ubuntu) to check if Apache is running. If you see in green text the words active (running) or if the last entry reads Started The Apache HTTP Server. then you're good.

Step 5) We will establish a SSL connection with the reverse proxy, and then the reverse proxy will communicate to keyCloak over http. Because this http communication is happening on the same machine, you're still secure. We can use Certbot to setup auto-renewing certificates.

If this type of encryption is not good enough, and your security policy requires end-to-end encryption, you will have to figure out how to setup SSL through WildFly, instead of using a reverse proxy.

Note: I was never actually able to get https to work properly with the admin portal. Perhaps this may have just been a bug in the beta version of Keycloak 4.0 that I'm using. You're suppose to be able to set the SSL level to only require it for external requests, but this did not seem to work, which is why we set https to none in step #2. From here on we will continue to use http over an SSH tunnel to manage the admin settings.

Step 6) Whenever you try to visit the site via https, you will trigger an HSTS policy which will auto-force http requests to redirect to https. Follow these instructions to clear the HSTS rule from Chrome, and then for the time being, do not visit the https version of the site again.

Step 7) Configure Apache. First find where your httpd.conf file is located. Your httpd.conf file is probably including config files from a separate directory. In my case, I found all of my config file in a conf.d directory located adjacent to the folder the httpd.conf file was in.

Once you find your conf files, change out, or add the following, virtual host entries in your conf files. Make sure you don't override the already present SSL options that where generated by certbot. When done, your config file should look something like this.

<VirtualHost *:80>
    RewriteEngine on

    #change https redirect_uri parameters to http
    RewriteCond %{request_uri}\?%{query_string} ^(.*)redirect_uri=https(.*)$
    RewriteRule . %1redirect_uri=http%2 [NE,R=302]

    #uncomment to force https
    #does not currently work
    #RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI}

    #forward the requests on to keycloak
    ProxyPreserveHost On    
    ProxyPass / http://127.0.0.1:8080/
    ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>

<IfModule mod_ssl.c>
<VirtualHost *:443>
    RewriteEngine on

    #Disable HSTS
    Header set Strict-Transport-Security "max-age=0; includeSubDomains;" env=HTTPS


    #change https redirect_uri parameters to http
    RewriteCond %{request_uri}\?%{query_string} ^(.*)redirect_uri=https(.*)$
    RewriteRule . %1redirect_uri=http%2 [NE,R=302]

    #forward the requests on to keycloak
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8080/
    ProxyPassReverse / http://127.0.0.1:8080/

    #Leave the items added by certbot alone
    #There should be a ServerName option
    #And a bunch of options to configure the location of the SSL cert files
    #Along with an option to include an additional config file

</VirtualHost>
</IfModule>

Step 8) Restart Apache. Use sudo systemctl restart httpd (CentOs) or sudo systemctl restart apache2 (Ubuntu).

Step 9) Before you have a chance to try to login to the server, since we told Keycloak to use http, we need to setup another method of connecting securely. This can be done by either installing a VPN service on the keycloak server, or by using SOCKS. I used a SOCKS proxy. In order to do this, you'll first need to setup dynamic port forwarding.

ssh -N -D 9905 [email protected]

Or set it up via Putty.

All traffic sent to port 9905 will now be securely routed through an SSH tunnel to your server. Make sure you whitelist port 9905 on your server's firewall.

Once you have dynamic port forwarding setup, you will need to setup your browser to use a SOCKS proxy on port 9905. Instructions here.

Step 10) You should now be able to login to the Keycloak admin portal. To connect to the website go to http://127.0.0.1, and the SOCKS proxy will take you to the admin console. Make sure you turn off the SOCKS proxy when you're done as it does utilize your server's resources, and will result in a slower internet speed for you if kept on.

Step 11) Don't ask me how long it took me to figure all of this out.

We setup wildcard DNS like they explained above. So the a record is *.yourname.com

Then all of the subdomains are actually going to the same place, but PHP treats each subdomain as a different account.

We use the following code:

$url=$_SERVER["REQUEST_URI"];
$account=str_replace(".yourdomain.com","",$url);

This code just sets the $account variable the same as the subdomain. You could then retrieve their files and other information based on their account.

This probably isn't as efficient as the ways they list above, but if you don't have access to BIND and/or limited .htaccess this method should work (as long as your host will setup the wildcard for you).

We actually use this method to connect to the customers database for a multi-company e-commerce application, but it may work for you as well.

An iframe is used to embed another document inside a html page.

If the form is to be submitted to an iframe within the form page, then it can be easily acheived using the target attribute of the tag.

Set the target attribute of the form to the name of the iframe tag.

<form action="action" method="post" target="output_frame">
    <!-- input elements here --> 
</form>
<iframe name="output_frame" src="" id="output_frame" width="XX" height="YY">
</iframe>           

Advanced iframe target use
This property can also be used to produce an ajax like experience, especially in cases like file upload, in which case where it becomes mandatory to submit the form, in order to upload the files

The iframe can be set to a width and height of 0, and the form can be submitted with the target set to the iframe, and a loading dialog opened before submitting the form. So, it mocks a ajax control as the control still remains on the input form jsp, with the loading dialog open.

Exmaple

<script>
$( "#uploadDialog" ).dialog({ autoOpen: false, modal: true, closeOnEscape: false,                 
            open: function(event, ui) { jQuery('.ui-dialog-titlebar-close').hide(); } });

function startUpload()
{            
    $("#uploadDialog").dialog("open");
}

function stopUpload()
{            
    $("#uploadDialog").dialog("close");
}
</script>

<div id="uploadDialog" title="Please Wait!!!">
            <center>
            <img src="/imagePath/loading.gif" width="100" height="100"/>
            <br/>
            Loading Details...
            </center>
 </div>

<FORM  ENCTYPE="multipart/form-data" ACTION="Action" METHOD="POST" target="upload_target" onsubmit="startUpload()"> 
<!-- input file elements here--> 
</FORM>

<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;" onload="stopUpload()">   
        </iframe>

If you need to know the installed path under Windows without starting the python interpreter, have a look in the Windows registry.

Each installed Python version will have a registry key in either:

• HKLM\SOFTWARE\Python\PythonCore\versionnumber\InstallPath
• HKCU\SOFTWARE\Python\PythonCore\versionnumber\InstallPath

In 64-bit Windows, it will be under the Wow6432Node key:

• HKLM\SOFTWARE\Wow6432Node\Python\PythonCore\versionnumber\InstallPath

server {
    server_name xyz.com;
    root /home/ubuntu/project_folder/;

    client_max_body_size 10M;
    access_log  /var/log/nginx/project.access.log;
    error_log  /var/log/nginx/project.error.log;

    location /static {
        index index.html;
    }

    location /media {
        alias /home/ubuntu/project/media/;
    }
}

Server block to live the static page on nginx.

It doesn't seem to be padding, margin, or minheight/width. Setting android:background="@null" the button loses its touch animation, but it turns out that setting the background to anything at all fixes that border.

Even after viewing this thread, I had thought that ipython was a synonym for the python shell, in other words that typing python at the command line put one into ipython mode.

It is in fact, as referenced above, a very cool interactive shell (command line program) that can be installed from iPython.org or simply by running

pip install ipython

or the more extensive:

pip install ipython[notebook]

from the command line.

Here is a little extension I just put together.

public static class PositionsExtension
{
    public static Int32 Position<TSource>(this IEnumerable<TSource> source,
                                          Func<TSource, bool> predicate)
    {
        return Positions<TSource>(source, predicate).FirstOrDefault();
    }
    public static IEnumerable<Int32> Positions<TSource>(this IEnumerable<TSource> source, 
                                                        Func<TSource, bool> predicate)
    {
        if (typeof(TSource) is IDictionary)
        {
            throw new Exception("Dictionaries aren't supported");
        }

        if (source == null)
        {
            throw new ArgumentOutOfRangeException("source is null");
        }
        if (predicate == null)
        {
            throw new ArgumentOutOfRangeException("predicate is null");
        }
        var found = source.Where(predicate).First();
        var query = source.Select((item, index) => new
            {
                Found = ReferenceEquals(item, found),
                Index = index

            }).Where( it => it.Found).Select( it => it.Index);
        return query;
    }
}

Then you can call it like this.

IEnumerable<Int32> indicesWhereConditionIsMet = 
      ListItems.Positions(item => item == this);

Int32 firstWelcomeMessage ListItems.Position(msg =>               
      msg.WelcomeMessage.Contains("Hello"));

If you want to move that commit to another branch, get the SHA of the commit in question

git rev-parse HEAD

Then switch the current branch

git checkout other-branch

And cherry-pick the commit to other-branch

git cherry-pick <sha-of-the-commit>

The repository owner should give you a contributor permission:

I want to mention that in some win 10 systems, Microsoft pre-installed a python. Thus, in order to invoke the python installed in the anaconda, you should adjust the order of the environment variable to ensure that the anaconda has a higher priority.

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

In some cases it is necessary to add user agent to headers:

WebClient myWebClient = new WebClient();
myWebClient.DownloadFile(myStringWebResource, fileName);
myWebClient.Headers["User-Agent"] = "Mozilla/4.0 (Compatible; Windows NT 5.1; MSIE 6.0) (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

This was the solution to my case.

http://genjurosdojo.blogspot.com/2012/10/the-remote-server-returned-error-504.html

My solution was to have a proxy server accept REST, issue the SOAP request, and return result, using PHP.

Time to implement: 15-30 minutes.

Not most elegant, but solid.

echo "<script>
alert('There are no fields to generate a report');
window.location.href='admin/ahm/panel';
</script>";

and get rid of redirect line below.

You were mixing up two different worlds.

Non-recursively List Only Directories

I've seen some suggestions like having the image directory being a symbolic link pointing to a directory outside the web container, but will this approach work both on Windows and *nix environments?

If you adhere the *nix filesystem path rules (i.e. you use exclusively forward slashes as in /path/to/files), then it will work on Windows as well without the need to fiddle around with ugly File.separator string-concatenations. It would however only be scanned on the same working disk as from where this command is been invoked. So if Tomcat is for example installed on C: then the /path/to/files would actually point to C:\path\to\files.

If the files are all located outside the webapp, and you want to have Tomcat's DefaultServlet to handle them, then all you basically need to do in Tomcat is to add the following Context element to /conf/server.xml inside <Host> tag:

<Context docBase="/path/to/files" path="/files" />

This way they'll be accessible through http://example.com/files/.... For Tomcat-based servers such as JBoss EAP 6.x or older, the approach is basically the same, see also here. GlassFish/Payara configuration example can be found here and WildFly configuration example can be found here.

If you want to have control over reading/writing files yourself, then you need to create a Servlet for this which basically just gets an InputStream of the file in flavor of for example FileInputStream and writes it to the OutputStream of the HttpServletResponse.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Here's a basic example of such a servlet:

@WebServlet("/files/*")
public class FileServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException
    {
        String filename = URLDecoder.decode(request.getPathInfo().substring(1), "UTF-8");
        File file = new File("/path/to/files", filename);
        response.setHeader("Content-Type", getServletContext().getMimeType(filename));
        response.setHeader("Content-Length", String.valueOf(file.length()));
        response.setHeader("Content-Disposition", "inline; filename=\"" + file.getName() + "\"");
        Files.copy(file.toPath(), response.getOutputStream());
    }

}

When mapped on an url-pattern of for example /files/*, then you can call it by http://example.com/files/image.png. This way you can have more control over the requests than the DefaultServlet does, such as providing a default image (i.e. if (!file.exists()) file = new File("/path/to/files", "404.gif") or so). Also using the request.getPathInfo() is preferred above request.getParameter() because it is more SEO friendly and otherwise IE won't pick the correct filename during Save As.

You can reuse the same logic for serving files from database. Simply replace new FileInputStream() by ResultSet#getInputStream().

Hope this helps.

This is what worked for me, it required moment-tz as well as moment though.

const guess = moment.utc(date).tz(moment.tz.guess());
const correctTimezone = guess.format()

Test with a setTimeout, that worked for me and I could submit my form, refers to this answer https://stackoverflow.com/a/779785/5510314

$(document).ready(function () {
    $("#btnSubmit").click(function () {
        setTimeout(function () { disableButton(); }, 0);
    });

    function disableButton() {
        $("#btnSubmit").prop('disabled', true);
    }
});

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

You can use this to check the exception and the inner exception for a Win32Exception derived exception.

catch (Exception e) {  
    var w32ex = e as Win32Exception;
    if(w32ex == null) {
        w32ex = e.InnerException as Win32Exception;
    }    
    if(w32ex != null) {
        int code =  w32ex.ErrorCode;
        // do stuff
    }    
    // do other stuff   
}

Starting with C# 6, when can be used in a catch statement to specify a condition that must be true for the handler for a specific exception to execute.

catch (Win32Exception ex) when (ex.InnerException is Win32Exception) {
    var w32ex = (Win32Exception)ex.InnerException;
    var code =  w32ex.ErrorCode;
}

As in the comments, you really need to see what exception is actually being thrown to understand what you can do, and in which case a specific catch is preferred over just catching Exception. Something like:

  catch (BlahBlahException ex) {  
      // do stuff   
  }

Also System.Exception has a HRESULT

 catch (Exception ex) {  
     var code = ex.HResult;
 }

However, it's only available from .NET 4.5 upwards.

If your emulator x86 this method works your me.

You try this.

Let's say 'random.seed' gives a value to random value generator ('random.randint()') which generates these values on the basis of this seed. One of the must properties of random numbers is that they should be reproducible. When you put same seed, you get the same pattern of random numbers. This way you are generating them right from the start. You give a different seed- it starts with a different initial (above 3).

Given a seed, it will generate random numbers between 1 and 10 one after another. So you assume one set of numbers for one seed value.

I have made it from fastboot mode (Phone - Xiomi Mi5 Android 6.0.1)

Here is steps:

# check if device available
fastboot devices
# remove user data
fastboot erase userdata
# remove cache
fastboot erase cache 
# reboot device
fastboot reboot

there is another way wich you don't have to overwrite uibModal classes and use them if needed : you call $uibModal.open function with your own size type like "xlg" and then you define a class named "modal-xlg" like below :

.modal-xlg{
   width:1200px;
}

call $uibModal.open as :

 var modalInstance = $uibModal.open({
                ...  
                size: "xlg",
            });

and this will work . because whatever string you pass as size bootstrap will cocant it with "modal-" and this will play the role of class for window.

For Swift version, here is the code:

self.navigationItem.rightBarButtonItem = nil

self.navigationItem.leftBarButtonItem = nil

         WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
         AND C.I_EMPID = A.I_EMPID)

A note about getting the latest revision number:

Say I've cd-ed in a revisioned subdirectory (MyProjectDir). Then, if I call svnversion:

$ svnversion .
323:340

... I get "323:340", which I guess means: "you've got items here, ranging from revision 323 to 340".

Then, if I call svn info:

$ svn info
Path: .
URL: svn+ssh://server.com/path/to/MyProject/MyProjectDir
Repository Root: svn+ssh://server.com/path/to/MyProject
Repository UUID: 0000ffff-ffff-...
Revision: 323
Node Kind: directory
Schedule: normal
Last Changed Author: USER
Last Changed Rev: 323
Last Changed Date: 2011-11-09 18:34:34 +0000 (Wed, 09 Nov 2011)

... I get "323" as revision - which is actually the lowest revision of those that reported by svnversion!

We can then use svn info in recursive mode to get more information from the local directory:

> svn info -R | grep 'Path\|Revision'
Path: .
Revision: 323
Path: file1.txt
Revision: 333
Path: file2.txt
Revision: 327
Path: file3.txt
Revision: 323
Path: subdirA
Revision: 328
Path: subdirA/file1.txt
Revision: 339
Path: subdirA/file1.txt
Revision: 340
Path: file1.txt
Revision: 323
...

... (remove the grep to see the more details).

Finally, what to do when we want to check what is the latest revision of the online repository (in this case, @ server.com)? Then we again issue svn info, but with -r HEAD (note the difference between capital -R option previously, and lowercase -r now):

> svn info -r 'HEAD'
[email protected]'s password:
Path: MyProjectDir
URL: svn+ssh://server.com/path/to/MyProject/MyProjectDir
Repository Root: svn+ssh://server.com/path/to/MyProject
Repository UUID: 0000ffff-ffff-...
Revision: 340
Node Kind: directory
Last Changed Author: USER
Last Changed Rev: 340
Last Changed Date: 2011-11-11 01:53:50 +0000 (Fri, 11 Nov 2011)

The interesting thing is - svn info still refers to the current subdirectory (MyProjectDir), however, the online path is reported as MyProjectDir (as opposed to . for the local case) - and the online revision reported is the highest (340 - as opposed to the lowest one, 323 reported locally).

This line of code might not work in IE 8 because of native support problems.

$(".hidden").attr("placeholder", "Type here to search");

You can try importing a JQuery placeholder plugin for this task. Simply import it to your libraries and initiate from the sample code below.

$('input, textarea').placeholder();

Necromancing.
Actually, doing this correctly is a little bit trickier.

You first need to check if the primary-key exists for the column you want to set your foreign key to reference to.

In this example, a foreign key on table T_ZO_SYS_Language_Forms is created, referencing dbo.T_SYS_Language_Forms.LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

singletonList can hold instance of any object. Object state can be modify.

List<Character> list = new ArrayList<Character>();
list.add('X');
list.add('Y');
System.out.println("Initial list: "+ list);
List<List<Character>> list2 = Collections.singletonList(list);
list.add('Z');
System.out.println(list);
System.out.println(list2);

We can not define unmodifiableList like above.

To add and simplify Günter Zöchbauer's the example incase using (if...else) to set something else than background image :

<p [ngStyle]="value == 10 && { 'font-weight': 'bold' }">

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

The way to sleep your program in C++ is the Sleep(int) method. The header file for it is #include "windows.h."

For example:

#include "stdafx.h"
#include "windows.h"
#include "iostream"
using namespace std;

int main()
{
    int x = 6000;
    Sleep(x);
    cout << "6 seconds have passed" << endl;
    return 0;
}

The time it sleeps is measured in milliseconds and has no limit.

Second = 1000 milliseconds
Minute = 60000 milliseconds
Hour = 3600000 milliseconds

You can use the fmt= parameter and fill the value based on the following table :

Ex : your URL would become :

FYI: Same problem with running on a build server (Jenkins with msbuild 15 installed, driven from VS 2017 on a .NET Core 2.1 web project).

In my case it was the use of the "publish" target with msbuild that ignored the profile.

So my msbuild command started with:

msbuild /t:restore;build;publish

This correctly triggerred the publish process, but no combination or variation of "/p:PublishProfile=FolderProfile" ever worked to select the profile I wanted to use ("FolderProfile").

When I stopped using the publish target:

msbuild /t:restore;build /p:DeployOnBuild=true /p:PublishProfile=FolderProfile

I (foolishly) thought that it would make no difference, but as soon as I used the DeployOnBuild switch it correctly picked up the profile.

As others indicated, setting the WebChromeClient is needed to get alert() to work. It's sufficient to just set the default WebChromeClient():

mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebChromeClient(new WebChromeClient());

Thanks for all the comments below. Including John Smith's who indicated that you needed to enable JavaScript.

If your Python datetime object is timezone-aware than you should be careful to avoid errors around DST transitions (or changes in UTC offset for other reasons):

from datetime import datetime, timedelta
from tzlocal import get_localzone # pip install tzlocal

DAY = timedelta(1)
local_tz = get_localzone()   # get local timezone
now = datetime.now(local_tz) # get timezone-aware datetime object
day_ago = local_tz.normalize(now - DAY) # exactly 24 hours ago, time may differ
naive = now.replace(tzinfo=None) - DAY # same time
yesterday = local_tz.localize(naive, is_dst=None) # but elapsed hours may differ

In general, day_ago and yesterday may differ if UTC offset for the local timezone has changed in the last day.

For example, daylight saving time/summer time ends on Sun 2-Nov-2014 at 02:00:00 A.M. in America/Los_Angeles timezone therefore if:

import pytz # pip install pytz

local_tz = pytz.timezone('America/Los_Angeles')
now = local_tz.localize(datetime(2014, 11, 2, 10), is_dst=None)
# 2014-11-02 10:00:00 PST-0800

then day_ago and yesterday differ:

• day_ago is exactly 24 hours ago (relative to now) but at 11 am, not at 10 am as now
• yesterday is yesterday at 10 am but it is 25 hours ago (relative to now), not 24 hours.

pendulum module handles it automatically:

>>> import pendulum  # $ pip install pendulum

>>> now = pendulum.create(2014, 11, 2, 10, tz='America/Los_Angeles')
>>> day_ago = now.subtract(hours=24)  # exactly 24 hours ago
>>> yesterday = now.subtract(days=1)  # yesterday at 10 am but it is 25 hours ago

>>> (now - day_ago).in_hours()
24
>>> (now - yesterday).in_hours()
25

>>> now
<Pendulum [2014-11-02T10:00:00-08:00]>
>>> day_ago
<Pendulum [2014-11-01T11:00:00-07:00]>
>>> yesterday
<Pendulum [2014-11-01T10:00:00-07:00]>

TLDR

Use

• rake db:migrate If you wanna make changes to the schema
• rake db:reset If you wanna drop the database, reload the schema from schema.rb, and reseed the database
• rake db:schema:load If you wanna reset database to schema as provided in schema.rb (This will delete all data)

Explanations

rake db:schema:load will set up the schema as provided in schema.rb file. This is useful for a fresh install of app as it doesn't take as much time as db:migrate

Important note, db:schema:load will delete data on server.

rake db:migrate makes changes to the existing schema. Its like creating versions of schema. db:migrate will look in db/migrate/ for any ruby files and execute the migrations that aren't run yet starting with the oldest. Rails knows which file is the oldest by looking at the timestamp at the beginning of the migration filename. db:migrate comes with a benefit that data can also be put in the database. This is actually not a good practice. Its better to use rake db:seed to add data.

rake db:migrate provides tasks up, down etc which enables commands like rake db:rollback and makes it the most useful command.

rake db:reset does a db:drop and db:setup
It drops the database, create it again, loads the schema, and initializes with the seed data

Relevant part of the commands from databases.rake

namespace :schema do
  desc 'Creates a db/schema.rb file that is portable against any DB supported by Active Record'
  task :dump => [:environment, :load_config] do
    require 'active_record/schema_dumper'
    filename = ENV['SCHEMA'] || File.join(ActiveRecord::Tasks::DatabaseTasks.db_dir, 'schema.rb')
    File.open(filename, "w:utf-8") do |file|
      ActiveRecord::SchemaDumper.dump(ActiveRecord::Base.connection, file)
    end
    db_namespace['schema:dump'].reenable
  end

  desc 'Loads a schema.rb file into the database'
  task :load => [:environment, :load_config, :check_protected_environments] do
    ActiveRecord::Tasks::DatabaseTasks.load_schema_current(:ruby, ENV['SCHEMA'])
  end

  # desc 'Drops and recreates the database from db/schema.rb for the current environment and loads the seeds.'
  task :reset => [ 'db:drop', 'db:setup' ]

namespace :migrate do
  # desc  'Rollbacks the database one migration and re migrate up (options: STEP=x, VERSION=x).'
  task :redo => [:environment, :load_config] do
    if ENV['VERSION']
      db_namespace['migrate:down'].invoke
      db_namespace['migrate:up'].invoke
    else
      db_namespace['rollback'].invoke
      db_namespace['migrate'].invoke
    end
  end

Traditionally, JS was intended for short, quick-running pieces of code. If you had major calculations going on, you did it on a server - the idea of a JS+HTML app that ran in your browser for long periods of time doing non-trivial things was absurd.

Of course, now we have that. But, it'll take a bit for browsers to catch up - most of them have been designed around a single-threaded model, and changing that is not easy. Google Gears side-steps a lot of potential problems by requiring that background execution is isolated - no changing the DOM (since that's not thread-safe), no accessing objects created by the main thread (ditto). While restrictive, this will likely be the most practical design for the near future, both because it simplifies the design of the browser, and because it reduces the risk involved in allowing inexperienced JS coders mess around with threads...

@marcio:

Why is that a reason not to implement multi-threading in Javascript? Programmers can do whatever they want with the tools they have.

So then, let's not give them tools that are so easy to misuse that every other website i open ends up crashing my browser. A naive implementation of this would bring you straight into the territory that caused MS so many headaches during IE7 development: add-on authors played fast and loose with the threading model, resulting in hidden bugs that became evident when object lifecycles changed on the primary thread. BAD. If you're writing multi-threaded ActiveX add-ons for IE, i guess it comes with the territory; doesn't mean it needs to go any further than that.

use Jackson (https://github.com/FasterXML/jackson) from http://json.org/

HashMap<String,Object> result =
       new ObjectMapper().readValue(<JSON_OBJECT>, HashMap.class);

You can parse the string as though it was a CSV (Comma Separated Value) string. PHP has a great build-in function called str_getcsv which converts a CSV string to an array.

// This is an example to test with
$enum_or_set = "'blond','brunette','redhead'";

// Here is the parser
$options = str_getcsv($enum_or_set, ',', "'");

// Output the value
print_r($options);

This should give you something similar to the following:

Array
(
    [0] => blond
    [1] => brunette
    [2] => redhead
)

This method also allows you to have single quotes in your strings (notice the use of two single quotes):

$enum_or_set = "'blond','brunette','red''head'";

Array
(
    [0] => blond
    [1] => brunette
    [2] => red'head
)

For more information on the str_getcsv function, check the PHP manual: http://uk.php.net/manual/en/function.str-getcsv.php

I just found this :

 private static bool TrySetSuppressScriptErrors(WebBrowser webBrowser, bool value)
    {
        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
            object axIWebBrowser2 = field.GetValue(webBrowser);
            if (axIWebBrowser2 != null)
            {
                axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { value });
                return true;
            }
        }

        return false;
    }

usage example to set webBrowser to silent : TrySetSuppressScriptErrors(webBrowser,true)

Just pass parameter like body - The content(query) from the customer
subject - subject that defined in mail subject
username - nothing name anything
mail - mail (required)

   public static bool SendMail(String body, String subject, string username, String mail)
    {
        bool isSendSuccess = false;
        try
        {
            var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
            var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
            var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
            var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
            var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();


            MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName),
                new MailAddress(mail, username));
            message.Subject = subject;
            message.IsBodyHtml = true;
            message.Body = body;

            var client = new SmtpClient();
            client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
            client.Host = smtpHost;
            client.EnableSsl = false;
            client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
            client.Send(message);
            isSendSuccess = true;
        }
        catch (Exception ex)
        {
            throw (new Exception("Mail send failed to loginId " + mail + ", though registration done."+ex.ToString()+"\n"+ex.StackTrace));
        }

        return isSendSuccess;
    }

if your using go daddy server this work . add this in web.config

  <appSettings>
    ---other ---setting

    <add key="FromEmailAddress" value="[email protected]" />
    <add key="FromEmailDisplayName" value="anyname" />
    <add key="FromEmailPassword" value="mypassword@" />
    <add key="SMTPHost" value="relay-hosting.secureserver.net" />
    <add key="SMTPPort" value="25" />

</appSettings>

if you are using localhost or vps server change this configuration to this

 <appSettings>
    ---other ---setting

    <add key="FromEmailAddress" value="[email protected]" />
    <add key="FromEmailDisplayName" value="anyname" />
    <add key="FromEmailPassword" value="mypassword@" />
    <add key="SMTPHost" value="smtp.gmail.com" /> 
    <add key="SMTPPort" value="587" />
</appSettings>

change the code

          client.EnableSsl = true;

if your are using gmail please enable secure app. using this link https://myaccount.google.com/lesssecureapps?pli=1&rapt=AEjHL4Pd6h3XxE663Flvd-FfeRXxW_eNrIsGTBlZklgkAHZEeuHvheCQuZ1-djB9uIWaB-2EV7hyLCU0dWKA7D0JzYKe4ZRkuA

Its a new operator for combined comparison. Similar to strcmp() or version_compare() in behavior, but it can be used on all generic PHP values with the same semantics as <, <=, ==, >=, >. It returns 0 if both operands are equal, 1 if the left is greater, and -1 if the right is greater. It uses exactly the same comparison rules as used by our existing comparison operators: <, <=, ==, >= and >.

Note that Date.getDate only returns the day of the month. You can add a day by calling Date.setDate and appending 1.

// Create new Date instance
var date = new Date()

// Add a day
date.setDate(date.getDate() + 1)

JavaScript will automatically update the month and year for you.

EDIT:
Here's a link to a page where you can find all the cool stuff about the built-in Date object, and see what's possible: Date.

I had Python 2.7 and wanted to be able to switch to Python 3 inside of Jupyter.

These steps worked for me on a Windows Anaconda Command Prompt:

conda update conda
conda create -n py33 python=3.3 anaconda
activate py33
ipython kernelspec install-self
deactivate

Now after opening ipython notebook with the usual command for Python2.7, Python3.3 is also available when creating a new notebook.

this error is coming because of appender file location you have provided is not reachable with current user access.

Quick Solution, change the log4j.appender.FILE.File setting to point to file using absolute path which location is reachable to the current user you have logged in, for example /tmp/myapp.log. Now You should not get an error.

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:

var mvar = "";
$(".mbox").each(function() {
    console.log($(this).html());
    mvar += $(this).html();
});
console.log(mvar);

Just make a new folder inside C:\xampp\htdocs like C:\xampp\htdocs\test and place your index.php or whatever file in it. Access it by browsing localhost/test/

Good luck!

Alternatively, this solution works with both Apache2 version < 2.4 as well as >= 2.4. Make sure that the "version" module is enabled:

a2enmod version

And then use this code instead:

<IfVersion < 2.4>
    Allow from all
</IfVersion>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>

x+=y is shorthand in many languages for set x to x + y. The sum will be, as hinted by its name, the sum of the numbers in data.

In Laravel 5.1 I needed a global variable populated with model data accessible in all views.

I followed a similar approach to ollieread's answer and was able to use my variable ($notifications) in any view.

My controller location: /app/Http/Controllers/Controller.php

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

use App\Models\Main as MainModel;
use View;

abstract class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function __construct() {
        $oMainM = new MainModel;
        $notifications = $oMainM->get_notifications();
        View::share('notifications', $notifications);
    }
}

My model location: /app/Models/Main.php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use DB;

class Main extends Model
{
    public function get_notifications() {...

The code marked as the solution did not work for me. This was my solution.

Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:

static Object[] EmptyObjArray = new Object[10000];

public static void clear(Object[] arr) {
    final int arrlen = arr.length;
    clear(arr, arrlen);
}

public static void clear(Object[] arr, int arrlen) {
    int count = 0;
    final int length = EmptyObjArray.length;
    while( arrlen - count > length) {
        System.arraycopy(EmptyObjArray,0,arr,count, length);
        count += length;
    }
    System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}

The simulator puts the file in ~/Library/Developer/CoreSimulator/Devices/... but the path after /Devices is different for everyone.

Use this handy method. It returns the path of the temporary directory for the current user and takes no argument.

NSString * NSTemporaryDirectory ( void );

So in my ViewController class I usually put this line in my viewDidLoad just for a reference when I need to grab my CoreData stored file. Hope this helps.

  NSLog(@"FILE PATH :%@", NSTemporaryDirectory());

(Note: to go to the path, from the finder menu click on Go and type ~/Library to open hidden directory then in the Finder Window you can click on the path shown on your console.)

As for the meaning of each character described in C Primer Plus, what you expected is an 'correct' answer. It should be true for some computer architectures and compilers, but unfortunately not yours.

I wrote a simple c program to repeat your test, and got that 'correct' answer. I was using Mac OS and gcc.

Also, I am very curious what is the compiler that you were using. :)

This issue could be because of wrong entity framework reference or sometimes the Class name not matching the entity name in database. Make sure the Table name matches with class name.

I had this issue too, after following this guide, it was simply 1 additional patch that was required to get past the

Rule "Prior Visual Studio 2010 instances requiring update." failed.

Was to locate this file, and patch my machine

VS10sp1-KB983509.msp

Simply do a file search on the installation media for SQL Server 2012, in my case it was in \redist\VisualStudioShell (whereas in the guide it's listed as being in a different location).

Then hit 're-run'.

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

dir /s /b /a:d>output.txt will port it to a text file

Depends on what you mean by better. This works if your goal is removal of redundancy.

s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))

You can use the TryParse method that returns true if it successful:

Age age;

if(Enum.TryParse<Age>("myString", out age))
{
   //Here you can use age
}

Here's a mmap example:

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

/*
 * pvtmMmapAlloc - creates a memory mapped file area.  
 * The return value is a page-aligned memory value, or NULL if there is a failure.
 * Here's the list of arguments:
 * @mmapFileName - the name of the memory mapped file
 * @size - the size of the memory mapped file (should be a multiple of the system page for best performance)
 * @create - determines whether or not the area should be created.

File.renameTo from Java IO can be used to move a file in Java. Also see this SO question.

Try like this,

>>> s = set([1,2,3])
>>> s = list(s)
>>> s
[1, 2, 3]

>>> str = ', '.join(str(e) for e in s)
>>> str = 'set(%s)' % str
>>> str
'set(1, 2, 3)'

char originalString[] = "THESTRINGHASNOSPACES";

    char aux[5];
    int j=0;
    for(int i=0;i<strlen(originalString);i++){
        aux[j] = originalString[i];
        if(j==3){
            aux[j+1]='\0'; 
            printf("%s\n",aux);
            j=0;
        }else{
            j++;
        }
    }

Following Justin's example, the command below works in Postgres:

alter table foo alter column col2 set default 'bar';

Try this:

\begin{flalign*}
    &|\vec a| = \sqrt{3^{2}+1^{2}} = \sqrt{10} & \\
    &|\vec b| = \sqrt{1^{2}+23^{2}} = \sqrt{530} &\\ 
    &\cos v = \frac{26}{\sqrt{10} \cdot \sqrt{530}} &\\
    &v = \cos^{-1} \left(\frac{26}{\sqrt{10} \cdot \sqrt{530}}\right) &\\
\end{flalign*}

The & sign separates two columns, so an & at the beginning of a line means that the line starts with a blank column.

Anything that matches something ending with a --- .*a$ So when you match the regex, negate the condition or alternatively you can also do .*[^a]$ where [^a] means anything which is not a

do in your shell: $ env |grep LANG

This will probably show that your shell is not using a utf-8 locale.

Runnable is an interface defined as so:

interface Runnable {
    public void run();
}

To make a class which uses it, just define the class as (public) class MyRunnable implements Runnable {

It can be used without even making a new Thread. It's basically your basic interface with a single method, run, that can be called.

If you make a new Thread with runnable as it's parameter, it will call the run method in a new Thread.

It should also be noted that Threads implement Runnable, and that is called when the new Thread is made (in the new thread). The default implementation just calls whatever Runnable you handed in the constructor, which is why you can just do new Thread(someRunnable) without overriding Thread's run method.

You are asking a question about two different things:

1. Meta inner class in Django models:

   This is just a class container with some options (metadata) attached to the model. It defines such things as available permissions, associated database table name, whether the model is abstract or not, singular and plural versions of the name etc.

   Short explanation is here: Django docs: Models: Meta options

   List of available meta options is here: Django docs: Model Meta options

   For latest version of Django: Django docs: Model Meta options

2. Metaclass in Python:

   The best description is here: What are metaclasses in Python?

It means not equal to .

It's the same as != in C-like languages. but <> is ISO Standard and

!= Not equal to (not ISO standard)

I know it is a 100 year old post, but anyway, thought it might be useful to someone. You can put an invisible image somewhere on the page pointing to the url that needs to run in the background, like this:

<img src="run-in-background.php" border="0" alt="" width="1" height="1" />

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

Some changes to this coming in v1.54, see https://github.com/microsoft/vscode-docs/blob/vnext/release-notes/v1_54.md#updated-application-menu-settings

Updated Application Menu Settings

The window.menuBarVisibility setting for the application menu visibility has been updated to better reflect the options. Two primary changes have been made.

First, the default option for the setting has been renamed to classic.

Second, the Show Menu Bar entry in the the application menu bar now toggles between the classic and compact options. To hide it completely, you can update the setting, or use the context menu of the Activity Bar when in compact mode.

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

Based on other answers and my tries, best experience would be first installing, pillow and scipy, then using the following starting code on your jupyter notebook:

%matplotlib inline
from matplotlib.pyplot import imshow
from scipy.misc import imread

imshow(imread('image.jpg', 1))

What I was looking for is a way to fetch the data

so I used this $data = $this->db->get('table_name')->result_array();

and then fetched my data just as you operate on array objects.

$data[0]['field_name']

No need to worry about type casting or anything just straight to the point.

So it worked for me.

IsNullOrEmpty is essentially shorthand for the following:

return str == null || str == String.Empty;

So, no there is no function that just checks for nulls because it would be too simple. obj != null is the correct way. But you can create such a (superfluous) function yourself using the following extension:

public bool IsNull(this object obj)
{
    return obj == null;
}

Then you are able to run anyObject.IsNull().

Well, this is a very simple way to validate a number different to 0.

if (+inputNum)

It will be NaN if inputNum is not a number or false if it is 0

npm install bootstrap --save

and add relevent files into angular.json file under the style property for css files and under scripts for JS files.

 "styles": [
  "../node_modules/bootstrap/dist/css/bootstrap.min.css",
   ....
]

Unless you have overlapping variable names, its really just for clarity when you're reading the code.

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

I'm giving you the fiddle_demo

You need to change in this markup

 <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar collapse">

change the

data-target=".navbar collapse"

to

data-target=".navbar-collapse"

Reason : The value of data-target is a any class name of the associated nav div. In this case it is

<div class="collapse navbar-collapse">  <-- Look at here
     <ul class="nav navbar-nav navbar-right">
     .....
</div>

Js Fiddle Demo

You can achieve this with a DockPanel:

<DockPanel Width="300">
    <TextBlock>Left</TextBlock>
    <Button HorizontalAlignment="Right">Right</Button>
</DockPanel>

The difference is that a StackPanel will arrange child elements into single line (either vertical or horizontally) whereas a DockPanel defines an area where you can arrange child elements either horizontally or vertically, relative to each other (the Dock property changes the position of an element relative to other elements within the same container. Alignment properties, such as HorizontalAlignment, change the position of an element relative to its parent element).

Update

As pointed out in the comments you can also use the FlowDirection property of a StackPanel. See @D_Bester's answer.

If you're using HTML5 you don't need to go to any great lengths to perform validation. Just use -

<input type="number" step="any" />

The step attribute allows the decimal point to be valid.

You can use str_replace(), which is defined as:

str_replace($search, $replace, $subject)

So you could write the code as:

$subject = 'REGISTER 11223344 here' ;
$search = '11223344' ;
$trimmed = str_replace($search, '', $subject) ;
echo $trimmed ;

If you need better matching via regular expressions you can use preg_replace().

Native Groovy GET and POST

// GET
def get = new URL("https://httpbin.org/get").openConnection();
def getRC = get.getResponseCode();
println(getRC);
if(getRC.equals(200)) {
    println(get.getInputStream().getText());
}

// POST
def post = new URL("https://httpbin.org/post").openConnection();
def message = '{"message":"this is a message"}'
post.setRequestMethod("POST")
post.setDoOutput(true)
post.setRequestProperty("Content-Type", "application/json")
post.getOutputStream().write(message.getBytes("UTF-8"));
def postRC = post.getResponseCode();
println(postRC);
if(postRC.equals(200)) {
    println(post.getInputStream().getText());
}

I use EventBus library to update Fragment content in ViewPager. The logic is simple, just like document of EventBus how to do. It is no need to control FragmentPagerAdapter instance. The code is here:

1: Define events

Define which message which is needed to update.

public class UpdateCountEvent {
    public final int count;

    public UpdateCountEvent(int count) {
        this.count = count;
    }
}

2.Prepare subscribers

Write below code in the Fragment which is needed update.

@Override
public void onStart() {
    super.onStart();
    EventBus.getDefault().register(this);
}

@Override
public void onStop() {
    EventBus.getDefault().unregister(this);  
    super.onStop();
}

public void onEvent(UpdateCountEvent event) {//get update message
    Toast.makeText(getActivity(), event.count, Toast.LENGTH_SHORT).show();
}

3.Post events

Write below code in other Activity or other Fragment which needs to update parameter

//input update message
EventBus.getDefault().post(new UpdateCountEvent(count));

I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.

select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
    select o.orderID, o.price * o.qty as subtotal
    from product p inner join orderitem o on p.ProductID= o.productID
    where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal

Your real problem is that you are calling "sc.nextLine()" MORE TIMES than the number of lines.

For example, if you have only TEN input lines, then you can ONLY call "sc.nextLine()" TEN times.

Every time you call "sc.nextLine()", one input line will be consumed. If you call "sc.nextLine()" MORE TIMES than the number of lines, you will have an exception called

      "java.util.NoSuchElementException: No line found".

If you have to call "sc.nextLine()" n times, then you have to have at least n lines.

Try to change your code to match the number of times you call "sc.nextLine()" with the number of lines, and I guarantee that your problem will be solved.

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

jQuery also has a utility for this: http://api.jquery.com/jQuery.extend/.

Taken from the jQuery documentation:

// Merge options object into settings object
var settings = { validate: false, limit: 5, name: "foo" };
var options  = { validate: true, name: "bar" };
jQuery.extend(settings, options);

// Now the content of settings object is the following:
// { validate: true, limit: 5, name: "bar" }

The above code will mutate the existing object named settings.

If you want to create a new object without modifying either argument, use this:

var defaults = { validate: false, limit: 5, name: "foo" };
var options = { validate: true, name: "bar" };

/* Merge defaults and options, without modifying defaults */
var settings = $.extend({}, defaults, options);

// The content of settings variable is now the following:
// {validate: true, limit: 5, name: "bar"}
// The 'defaults' and 'options' variables remained the same.

To Read JSON File, refer this simple example

Your JSON File (StreamingAssets/Player.json)

{
    "Name": "MyName",
    "Level": 4
}

C# Script

public class Demo
{
    public void ReadJSON()
    {
        string path = Application.streamingAssetsPath + "/Player.json";
        string JSONString = File.ReadAllText(path);
        Player player = JsonUtility.FromJson<Player>(JSONString);
        Debug.Log(player.Name);
    }
}

[System.Serializable]
public class Player
{
    public string Name;
    public int Level;
}

• .length is a field, containing the capacity (NOT the number of elements the array contains at the moment) of arrays.

• length() is a method used by Strings (amongst others), it returns the number of chars in the String; with Strings, capacity and number of containing elements (chars) have the same value.

• size() is a method implemented by all members of Collection (lists, sets, stacks,...). It returns the number of elements (NOT the capacity; some collections even don´t have a defined capacity) the collection contains.

Use keyup instead of keypress. This gets all the key codes when the user presses something

You need to use the .toFixed() method

It takes as a parameter the number of digits to show after the decimal point.

$(document).ready(function() {
  $('.add').click(function() {
     var value = parseFloat($('#total').text()) + parseFloat($(this).data('amount'))/100
     $('#total').text( value.toFixed(2) );
  });
})

Array of arrays (jagged arrays) are faster than multi-dimensional arrays and can be used more effectively. Multidimensional arrays have nicer syntax.

If you write some simple code using jagged and multidimensional arrays and then inspect the compiled assembly with an IL disassembler you will see that the storage and retrieval from jagged (or single dimensional) arrays are simple IL instructions while the same operations for multidimensional arrays are method invocations which are always slower.

Consider the following methods:

static void SetElementAt(int[][] array, int i, int j, int value)
{
    array[i][j] = value;
}

static void SetElementAt(int[,] array, int i, int j, int value)
{
    array[i, j] = value;
}

Their IL will be the following:

.method private hidebysig static void  SetElementAt(int32[][] 'array',
                                                    int32 i,
                                                    int32 j,
                                                    int32 'value') cil managed

                                                    int32 j,

When using jagged arrays you can easily perform such operations as row swap and row resize. Maybe in some cases usage of multidimensional arrays will be more safe, but even Microsoft FxCop tells that jagged arrays should be used instead of multidimensional when you use it to analyse your projects.

This code might work for non-.NET Core MVC controllers:

this.HttpContext.Response.StatusCode = 418; // I'm a teapot
return Json(new { status = "mer" }, JsonRequestBehavior.AllowGet);

Give a try to this

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    // TODO Auto-generated method stub

    FragmentManager manager = ((Fragment) object).getFragmentManager();
    FragmentTransaction trans = manager.beginTransaction();
    trans.remove((Fragment) object);
    trans.commit();

    super.destroyItem(container, position, object);
}

you can upload file using jsp /servlet.

<form action="UploadFileServlet" method="post">
  <input type="text" name="description" />
  <input type="file" name="file" />
  <input type="submit" />
</form>

on the other hand server side. use following code.

     package com.abc..servlet;

I haven't tested on other Laravel versions but on 5.3-5.8 you reference the query parameter as if it were a member of the Request class.

1. Url

http://example.com/path?page=2

2. In a route callback or controller action using magic method Request::__get()

Route::get('/path', function(Request $request){
 dd($request->page);
}); 

//or in your controller
public function foo(Request $request){
 dd($request->page);
}

//NOTE: If you are wondering where the request instance is coming from, Laravel automatically injects the request instance from the IOC container
//output
"2"

3. Default values

We can also pass in a default value which is returned if a parameter doesn't exist. It's much cleaner than a ternary expression that you'd normally use with the request globals

   //wrong way to do it in Laravel
   $page = isset($_POST['page']) ? $_POST['page'] : 1; 

   //do this instead
   $request->get('page', 1);

   //returns page 1 if there is no page
   //NOTE: This behaves like $_REQUEST array. It looks in both the
   //request body and the query string
   $request->input('page', 1);

4. Using request function

$page = request('page', 1);
//returns page 1 if there is no page parameter in the query  string
//it is the equivalent of
$page = 1; 
if(!empty($_GET['page'])
   $page = $_GET['page'];

The default parameter is optional therefore one can omit it

5. Using Request::query()

While the input method retrieves values from entire request payload (including the query string), the query method will only retrieve values from the query string

//this is the equivalent of retrieving the parameter
//from the $_GET global array
$page = $request->query('page');

//with a default
$page = $request->query('page', 1);

6. Using the Request facade

$page = Request::get('page');

//with a default value
$page = Request::get('page', 1);

This can be done using StackWalker since Java 9.

public static String getCurrentMethodName() {
    return StackWalker.getInstance()
                      .walk(s -> s.skip(1).findFirst())
                      .get()
                      .getMethodName();
}

public static String getCallerMethodName() {
    return StackWalker.getInstance()
                      .walk(s -> s.skip(2).findFirst())
                      .get()
                      .getMethodName();
}

StackWalker is designed to be lazy, so it's likely to be more efficient than, say, Thread.getStackTrace which eagerly creates an array for the entire callstack. Also see the JEP for more information.

For the basic tooltip, you want:

<span title="This is my tooltip"> Hover on me to see tooltip! </span>

The only issue I see are relative links and templates not being properly loaded because of this.

from the docs regarding HTML5 mode

Relative links

Be sure to check all relative links, images, scripts etc. You must either specify the url base in the head of your main html file (<base href="/my-base">) or you must use absolute urls (starting with /) everywhere because relative urls will be resolved to absolute urls using the initial absolute url of the document, which is often different from the root of the application.

In your case you can add a forward slash / in href attributes ($location.path does this automatically) and also to templateUrl when configuring routes. This avoids routes like example.com/tags/another and makes sure templates load properly.

Here's an example that works:

<div>
    <a href="/">Home</a> | 
    <a href="/another">another</a> | 
    <a href="/tags/1">tags/1</a>
</div>
<div ng-view></div>

And

app.config(function($locationProvider, $routeProvider) {
  $locationProvider.html5Mode(true);
  $routeProvider
    .when('/', {
      templateUrl: '/partials/template1.html', 
      controller: 'ctrl1'
    })
    .when('/tags/:tagId', {
      templateUrl: '/partials/template2.html', 
      controller:  'ctrl2'
    })
    .when('/another', {
      templateUrl: '/partials/template1.html', 
      controller:  'ctrl1'
    })
    .otherwise({ redirectTo: '/' });
});

If using Chrome you will need to run this from a server.

No, a view consists of a single SELECT statement. You cannot create or drop tables in a view.

Maybe a common table expression (CTE) can solve your problem. CTEs are temporary result sets that are defined within the execution scope of a single statement and they can be used in views.

Example (taken from here) - you can think of the SalesBySalesPerson CTE as a temporary table:

CREATE VIEW vSalesStaffQuickStats
AS
  WITH SalesBySalesPerson (SalesPersonID, NumberOfOrders, MostRecentOrderDate)
      AS
      (
            SELECT SalesPersonID, COUNT(*), MAX(OrderDate)
            FROM Sales.SalesOrderHeader
            GROUP BY SalesPersonID
      )
  SELECT E.EmployeeID,
         EmployeeOrders = OS.NumberOfOrders,
         EmployeeLastOrderDate = OS.MostRecentOrderDate,
         E.ManagerID,
         ManagerOrders = OM.NumberOfOrders,
         ManagerLastOrderDate = OM.MostRecentOrderDate
  FROM HumanResources.Employee AS E
  INNER JOIN SalesBySalesPerson AS OS ON E.EmployeeID = OS.SalesPersonID
  LEFT JOIN SalesBySalesPerson AS OM ON E.ManagerID = OM.SalesPersonID
GO

Performance considerations

Which are more performant, CTE or temporary tables?

File modification:

ls -t

Inode change:

ls -tc

File access:

ls -tu

"Newest" one at the bottom:

ls -tr

None of this is a creation time. Most Unix filesystems don't support creation timestamps.

As suggested above the inclusion of

/usr/lib/openmpi/include 

in the include path takes care of this (in my case)

You can try this with Color.FromArgb:

Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));

If you are using one of the built-in controller instances, then one of the parameters to your controller method will be the Request object. You can call request.getParameter("value1") to get the POST (or PUT) data value.

If you are using Spring MVC annotations, you can add an annotated parameter to your method's parameters:

@RequestMapping(value = "/someUrl")
public String someMethod(@RequestParam("value1") String valueOne) {
 //do stuff with valueOne variable here
}

If you have Python 2.6 or newer, use format:

'{0:.3g}'.format(num)

For Python 2.5 or older:

'%.3g'%(num)

Explanation:

{0}tells format to print the first argument -- in this case, num.

Everything after the colon (:) specifies the format_spec.

.3 sets the precision to 3.

g removes insignificant zeros. See http://en.wikipedia.org/wiki/Printf#fprintf

For example:

tests=[(1.00, '1'),
       (1.2, '1.2'),
       (1.23, '1.23'),
       (1.234, '1.23'),
       (1.2345, '1.23')]

for num, answer in tests:
    result = '{0:.3g}'.format(num)
    if result != answer:
        print('Error: {0} --> {1} != {2}'.format(num, result, answer))
        exit()
    else:
        print('{0} --> {1}'.format(num,result))

yields

1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23

Using Python 3.6 or newer, you could use f-strings:

In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'

Use psexec -s

The s switch will cause it to run under system account which is the same as running an elevated admin prompt. just used it to enable WinRM remotely.

JUnit test from inside eclipse gave me also NoClassDefFoundError. Running 'mvn clean test' from command line gave me following error on several jars: invalid LOC header (bad signature) Deleting these jars from local m2 repository and running 'mvn clean test' again solved my problem.

According to the man page the -P flag is:

-P prefix --directory-prefix=prefix Set directory prefix to prefix. The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree. The default is . (the current directory).

This mean that it only specifies the destination but where to save the directory tree. It does not flatten the tree into just one directory. As mentioned before the -nd flag actually does that.

@Jon in the future it would be beneficial to describe what the flag does so we understand how something works.

The answer that i am presenting is very simple, instead of using "px","em" or "%", i'll use "vw". In short it might look like this:- h1 {font-size: 5.9vw;} when used for heading purposes.

To expand on Berry's answer, that setting the access level to protected allows __get and __set to be used with explicitly declared properties (when accessed outside the class, at least) and the speed being considerably slower, I'll quote a comment from another question on this topic and make a case for using it anyway:

I agree that __get is more slow to a custom get function (doing the same things), this is 0.0124455 the time for __get() and this 0.0024445 is for custom get() after 10000 loops. – Melsi Nov 23 '12 at 22:32 Best practice: PHP Magic Methods __set and __get

According to Melsi's tests, considerably slower is about 5 times slower. That is definitely considerably slower, but also note that the tests show that you can still access a property with this method 10,000 times, counting time for loop iteration, in roughly 1/100 of a second. It is considerably slower in comparison with actual get and set methods defined, and that is an understatement, but in the grand scheme of things, even 5 times slower is never actually slow.

The computing time of the operation is still negligible and not worth considering in 99% of real world applications. The only time it should really be avoided is when you're actually going to be accessing the properties over 10,000 times in a single request. High traffic sites are doing something really wrong if they can't afford throwing a few more servers up to keep their applications running. A single line text ad on the footer of a high traffic site where the access rate becomes an issue could probably pay for a farm of 1,000 servers with that line of text. The end user is never going to be tapping their fingers wondering what is taking the page so long to load because your application's property access takes a millionth of a second.

I say this speaking as a developer coming from a background in .NET, but invisible get and set methods to the consumer is not .NET's invention. They simply aren't properties without them, and these magic methods are PHP's developer's saving grace for even calling their version of properties "properties" at all. Also, the Visual Studio extension for PHP does support intellisense with protected properties, with that trick in mind, I'd think. I would think with enough developers using the magic __get and __set methods in this way, the PHP developers would tune up the execution time to cater to the developer community.

Edit: In theory, protected properties seemed like it'd work in most situation. In practice, it turns out that there's a lot of times you're going to want to use your getters and setters when accessing properties within the class definition and extended classes. A better solution is a base class and interface for when extending other classes, so you can just copy the few lines of code from the base class into the implementing class. I'm doing a bit more with my project's base class, so I don't have an interface to provide right now, but here is the untested stripped down class definition with magic property getting and setting using reflection to remove and move the properties to a protected array:

/** Base class with magic property __get() and __set() support for defined properties. */
class Component {
    /** Gets the properties of the class stored after removing the original
     * definitions to trigger magic __get() and __set() methods when accessed. */
    protected $properties = array();

    /** Provides property get support. Add a case for the property name to
     * expand (no break;) or replace (break;) the default get method. When
     * overriding, call parent::__get($name) first and return if not null,
     * then be sure to check that the property is in the overriding class
     * before doing anything, and to implement the default get routine. */
    public function __get($name) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;
        if (is_subclass_of($caller['class'], get_class($this)))
            $max_access = ReflectionProperty::IS_PROTECTED;
        if ($caller['class'] == get_class($this))
            $max_access = ReflectionProperty::IS_PRIVATE;
        if (!empty($this->properties[$name])
            && $this->properties[$name]->class == get_class()
            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    return $this->properties[$name]->value;
            }
    }

    /** Provides property set support. Add a case for the property name to

    public function __set($name, $value) {
        $caller = array_shift(debug_backtrace());
        $max_access = ReflectionProperty::IS_PUBLIC;
        if (is_subclass_of($caller['class'], get_class($this)))
            $max_access = ReflectionProperty::IS_PROTECTED;

            && $this->properties[$name]->class == get_class()
            && $this->properties[$name]->access <= $max_access)
            switch ($name) {
                default:
                    $this->properties[$name]->value = $value;
            }
    }

    /** Constructor for the Component. Call first when overriding. */
    function __construct() {
        // Removing and moving properties to $properties property for magic
        // __get() and __set() support.
        $reflected_class = new ReflectionClass($this);
        $properties = array();
        foreach ($reflected_class->getProperties() as $property) {
            if ($property->isStatic()) { continue; }
            $properties[$property->name] = (object)array(
                'name' => $property->name, 'value' => $property->value
                , 'access' => $property->getModifier(), 'class' => get_class($this));
            unset($this->{$property->name}); }
        $this->properties = $properties;
    }
}

My apologies if there are any bugs in the code.

You should only use ’ if your intention is to make either a closed single quotation mark or an apostrophe. Both of these punctuation marks are curved in shape in most fonts. If your intent is to make a foot mark, go the other route. A foot mark is always a straight vertical mark.

It’s a matter of typography. One way is correct; the other is not.
