I have tried this and it is working fine for me:

sqlcmd -S servername -E -s~ -W -k1 -Q  "sql query here" > "\\file_path\file_name.csv"

Don't forget to include

import Image

In order to show it use this :

Image.open('pathToFile').show()

You've tagged this as C++ as well as C.

If you're using C++ things are a lot easier. The standard template library has a template called vector which allows you to dynamically build up a list of objects.

#include <stdio.h>
#include <vector>

typedef std::vector<char*> words;

int main(int argc, char** argv) {

        words myWords;

        myWords.push_back("Hello");
        myWords.push_back("World");

        words::iterator iter;
        for (iter = myWords.begin(); iter != myWords.end(); ++iter) {
                printf("%s ", *iter);
        }

        return 0;
}

If you're using C things are a lot harder, yes malloc, realloc and free are the tools to help you. You might want to consider using a linked list data structure instead. These are generally easier to grow but don't facilitate random access as easily.

#include <stdio.h>
#include <stdlib.h>

typedef struct s_words {
        char* str;
        struct s_words* next;
} words;

words* create_words(char* word) {
        words* newWords = malloc(sizeof(words));
        if (NULL != newWords){
                newWords->str = word;
                newWords->next = NULL;
        }
        return newWords;
}

void delete_words(words* oldWords) {
        if (NULL != oldWords->next) {
                delete_words(oldWords->next);
        }
        free(oldWords);
}

words* add_word(words* wordList, char* word) {
        words* newWords = create_words(word);
        if (NULL != newWords) {
                newWords->next = wordList;
        }
        return newWords;
}

int main(int argc, char** argv) {

        words* myWords = create_words("Hello");
        myWords = add_word(myWords, "World");

        words* iter;
        for (iter = myWords; NULL != iter; iter = iter->next) {
                printf("%s ", iter->str);
        }
        delete_words(myWords);
        return 0;
}

Yikes, sorry for the worlds longest answer. So WRT to the "don't want to use a linked list comment":

#include <stdio.h>  
#include <stdlib.h>

typedef struct {
    char** words;
    size_t nWords;
    size_t size;
    size_t block_size;
} word_list;

word_list* create_word_list(size_t block_size) {
    word_list* pWordList = malloc(sizeof(word_list));
    if (NULL != pWordList) {
        pWordList->nWords = 0;
        pWordList->size = block_size;
        pWordList->block_size = block_size;
        pWordList->words = malloc(sizeof(char*)*block_size);
        if (NULL == pWordList->words) {
            free(pWordList);
            return NULL;    
        }
    }
    return pWordList;
}

void delete_word_list(word_list* pWordList) {
    free(pWordList->words);
    free(pWordList);
}

int add_word_to_word_list(word_list* pWordList, char* word) {
    size_t nWords = pWordList->nWords;
    if (nWords >= pWordList->size) {
        size_t newSize = pWordList->size + pWordList->block_size;
        void* newWords = realloc(pWordList->words, sizeof(char*)*newSize); 
        if (NULL == newWords) {
            return 0;
        } else {    
            pWordList->size = newSize;
            pWordList->words = (char**)newWords;
        }

    }

    pWordList->words[nWords] = word;
    ++pWordList->nWords;


    return 1;
}

char** word_list_start(word_list* pWordList) {
        return pWordList->words;
}

char** word_list_end(word_list* pWordList) {
        return &pWordList->words[pWordList->nWords];
}

int main(int argc, char** argv) {

        word_list* myWords = create_word_list(2);
        add_word_to_word_list(myWords, "Hello");
        add_word_to_word_list(myWords, "World");
        add_word_to_word_list(myWords, "Goodbye");

        char** iter;
        for (iter = word_list_start(myWords); iter != word_list_end(myWords); ++iter) {
                printf("%s ", *iter);
        }

        delete_word_list(myWords);

        return 0;
}

For left padding add a string extension like this:

Swift 2.0 +

extension String {
    func padLeft (totalWidth: Int, with: String) -> String {
        let toPad = totalWidth - self.characters.count
        if toPad < 1 { return self }
        return "".stringByPaddingToLength(toPad, withString: with, startingAtIndex: 0) + self
    }
}

Swift 3.0 +

extension String {
    func padLeft (totalWidth: Int, with: String) -> String {
        let toPad = totalWidth - self.characters.count
        if toPad < 1 { return self }
        return "".padding(toLength: toPad, withPad: with, startingAt: 0) + self
    }
}

Using this method:

for myInt in 1...3 {
    print("\(myInt)".padLeft(totalWidth: 2, with: "0"))
}

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html You should be able to see if there are any issues with your ssl certificate chain. I am guessing that you have SSL chain issues. A short description of the problem is that there's actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

It appears that as of Java 7, David Santamaria's answer doesn't work reliably any more. It looks like you can still reliably use a Socket to test the connection, however.

private static boolean available(int port) {
    System.out.println("--------------Testing port " + port);
    Socket s = null;
    try {
        s = new Socket("localhost", port);

        // If the code makes it this far without an exception it means
        // something is using the port and has responded.
        System.out.println("--------------Port " + port + " is not available");
        return false;
    } catch (IOException e) {
        System.out.println("--------------Port " + port + " is available");
        return true;
    } finally {
        if( s != null){
            try {
                s.close();
            } catch (IOException e) {
                throw new RuntimeException("You should handle this error." , e);
            }
        }
    }
}

You 100% can do this on the server side...

     Protected Sub Button3_Click(sender As Object, e As System.EventArgs)
    MesgBox("Test")
End Sub

Private Sub MesgBox(ByVal sMessage As String)
    Dim msg As String
    msg = "<script language='javascript'>"
    msg += "alert('" & sMessage & "');"
    msg += "</script>"
    Response.Write(msg)
End Sub

here is actually a whole slew of ways to go about this http://www.sislands.com/coin70/week1/dialogbox.htm

This may sound like an unhelpful answer ... But why are you using a LinkButton for something purely client-side? Use a standard HTML anchor tag and set its onclick action to your Javascript.

If you need the server to generate the text of that link, then use an asp:Label as the content between the anchor's start and end tags.

If you need to dynamically change the script behavior based on server-side code, consider asp:Literal as a technique.

But unless you're doing server-side activity from the Click event of the LinkButton, there just doesn't seem to be much point to using it here.

As the name suggests 'untracked files' are the files which are not being tracked by git. They are not in your staging area, and were not part of any previous commits. If you want them to be versioned (or to be managed by git) you can do so by telling 'git' by using 'git add'. Check this chapter Recording Changes to the Repository in the Progit book which uses a nice visual to provide a good explanation about recording changes to git repo and also explaining the terms 'tracked' and 'untracked'.

Here are some demo & short cuts if you uses GitHub, the basic ideas are the same.

1. Open terminal like this

2. Paste the below command to terminal followed by a space and then paste the path of the .xcuserstate file simply like this

git rm --cached

3. Make sure you have the correct git ignore and then commit the code :)

The reason you are getting rejected is that your tag lost sync with the remote version. This is the same behaviour with branches.

sync with the tag from the remote via git pull --rebase <repo_url> +refs/tags/<TAG> and after you sync, you need to manage conflicts. If you have a diftool installed (ex. meld) git mergetool meld use it to sync remote and keep your changes.

The reason you're pulling with --rebase flag is that you want to put your work on top of the remote one so you could avoid other conflicts.

Also, what I don't understand is why would you delete the dev tag and re-create it??? Tags are used for specifying software versions or milestones. Example of git tags v0.1dev, v0.0.1alpha, v2.3-cr(cr - candidate release) and so on..

Another way you can solve this is issue a git reflog and go to the moment you pushed the dev tag on remote. Copy the commit id and git reset --mixed <commmit_id_from_reflog> this way you know your tag was in sync with the remote at the moment you pushed it and no conflicts will arise.

Finally found the answer!! Go to References --> right cilck on dll file that causing the problem --> select the properties --> check the version --> match the version in properties to web config

    <assemblyIdentity name="YourDllFile" publicKeyToken="2780ccd10d57b246"               culture="neutral" />

In my case, I was able to use a simple insert statement to bulk insert many rows into TABLE_A using just one column from TABLE_B and getting the other data elsewhere (sequence and a hardcoded value) :

INSERT INTO table_a (
    id,
    column_a,
    column_b
)
    SELECT
        table_a_seq.NEXTVAL,
        b.name,
        123
    FROM
        table_b b;

Result:

ID: NAME: CODE:
1, JOHN, 123
2, SAM, 123
3, JESS, 123

etc

You can use os.stat(path) call

http://docs.python.org/library/os.html#os.stat

Since you mentioned Task Manager, I'll guess you're using Windows. Assuming you're running your script within the editor, if you aren't opposed to quitting the editor at the same time as quitting the running program, the keyboard shortcut to end a process is:

Alt + F4

(By which I mean press the 'Alt' and 'F4' keys on your keyboard simultaneously.)

Alternatively, as mentioned in other answers,

Ctrl + C

should also work, but will not quit the editor.

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

In mac shell command line , use the following command:

plutil -insert NSAppTransportSecurity -xml "<array><string> hidden </string></array>" [location of your xcode project]/Info.plist 

The command will add all the necessary values into your plist file.

Swift 3:

If you want to go back to the previous view controller

_ = navigationController?.popViewController(animated: true)

If you want to go back to the root view controller

_ = navigationController?.popToRootViewController(animated: true)

Easiest way

<?php 
//-- you can modified it like you want

echo $width = "<script>document.write(screen.width);</script>";
echo $height = "<script>document.write(screen.height);</script>";

?>

I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line

; On windows: extension_dir = "ext"

I changed it to:

; On windows: extension_dir = "C:\php\ext"

And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.

Yeah mate i was trying to do the same in windows, and what helped me was a bit of lambdas with the root.state() method.

root = Tk()
root.bind('<Escape>', lambda event: root.state('normal'))
root.bind('<F11>', lambda event: root.state('zoomed'))

All of the answers here currently only talk about the system properties which are different from the environment variables that are more complex to set, esp. for tests. Thankfully, below class can be used for that and the class docs has good examples

EnvironmentVariables.html

A quick example from the docs, modified to work with @SpringBootTest

@SpringBootTest
public class EnvironmentVariablesTest {
   @ClassRule
   public final EnvironmentVariables environmentVariables = new EnvironmentVariables().set("name", "value");

   @Test
   public void test() {
     assertEquals("value", System.getenv("name"));
   }
 }

You can execute this in 2 simple statements:

row.names(samp) <- samp$names
samp[1] <- NULL

You can use pyuic4 command on shell: pyuic4 input.ui -o output.py

I would do the folowing:

Declare separetly the enum, in it´s own file:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { this.value = value; }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

Declare a new JPA entity named Right

@Entity
public class Right{
    @Id
    private Integer id;
    //FIElDS

    // constructor
    public Right(RightEnum rightEnum){
          this.id = rightEnum.getValue();
    }

    public Right getInstance(RightEnum rightEnum){
          return new Right(rightEnum);
    }


}

You will also need a converter for receiving this values (JPA 2.1 only and there´s a problem I´ll not discuss here with these enum´s to be directly persisted using the converter, so it will be a one way road only)

import mypackage.RightEnum;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

/**
 * 
 * 
 */
@Converter(autoApply = true)
public class RightEnumConverter implements AttributeConverter<RightEnum, Integer>{

    @Override //this method shoudn´t be used, but I implemented anyway, just in case
    public Integer convertToDatabaseColumn(RightEnum attribute) {
        return attribute.getValue();
    }

    @Override
    public RightEnum convertToEntityAttribute(Integer dbData) {
        return RightEnum.valueOf(dbData);
    }

}

The Authority entity:

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;

  // the **Entity** to map : 
  private Right right;

  // the **Enum** to map (not to be persisted or updated) : 
  @Column(name="COLUMN1", insertable = false, updatable = false)
  @Convert(converter = RightEnumConverter.class)
  private RightEnum rightEnum;

}

By doing this way, you can´t set directly to the enum field. However, you can set the Right field in Authority using

autorithy.setRight( Right.getInstance( RightEnum.READ ) );//for example

And if you need to compare, you can use:

authority.getRight().equals( RightEnum.READ ); //for example

Which is pretty cool, I think. It´s not totally correct, since the converter it´s not intended to be use with enum´s. Actually, the documentation says to never use it for this purpose, you should use the @Enumerated annotation instead. The problem is that there are only two enum types: ORDINAL or STRING, but the ORDINAL is tricky and not safe.

However, if it doesn´t satisfy you, you can do something a little more hacky and simpler (or not).

Let´s see.

The RightEnum:

public enum RightEnum {
      READ(100), WRITE(200), EDITOR (300);

      private int value;

      private RightEnum (int value) { 
            try {
                  this.value= value;
                  final Field field = this.getClass().getSuperclass().getDeclaredField("ordinal");
                  field.setAccessible(true);
                  field.set(this, value);
             } catch (Exception e) {//or use more multicatch if you use JDK 1.7+
                  throw new RuntimeException(e);
            }
      }


      @Override
      public static Etapa valueOf(Integer value){
           for( RightEnum r : RightEnum .values() ){
              if ( r.getValue().equals(value))
                 return r;
           }
           return null;//or throw exception
     }

      public int getValue() { return value; }


}

and the Authority entity

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {


  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  @Column(name = "AUTHORITY_ID")
  private Long id;


  // the **Enum** to map (to be persisted or updated) : 
  @Column(name="COLUMN1")
  @Enumerated(EnumType.ORDINAL)
  private RightEnum rightEnum;

}

In this second idea, its not a perfect situation since we hack the ordinal attribute, but it´s a much smaller coding.

I think that the JPA specification should include the EnumType.ID where the enum value field should be annotated with some kind of @EnumId annotation.

There is a JDK dropdown in "job name" -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

In the event that you already have a class and need to alternate between classes as oppose to add a class, you can chain toggle events:

$('li.multi').click(function(e) {
    $(this).toggleClass('opened').toggleClass('multi-opened');
});

out is more constraint version of ref.

In a method body, you need to assign to all out parameters before leaving the method. Also an values assigned to an out parameter is ignored, whereas ref requires them to be assigned.

So out allows you to do:

int a, b, c = foo(out a, out b);

where ref would require a and b to be assigned.

• If you still care a lot about support and performance in IE<10, it's best to ALWAYS make your script tags the last tags of your HTML body. That way, you're certain that the rest of the DOM has been loaded and you won't block and rendering.

• If you don't care too much anymore about IE<10, you might want to put your scripts in the head of your document and use defer to ensure they only run after your DOM has been loaded (<script type="text/javascript" src="path/to/script1.js" defer></script>). If you still want your code to work in IE<10, don't forget to wrap your code in a window.onload even, though!

If you don't have avahi installed then it's probably cups.

Your code work fine, provided the value in Sheet2!D2 exists in Sheet1!A:A. If it does not then error 1004 is raised.

To handle this case, try

Sub Demo()
    Dim MyStringVar1 As Variant
    On Error Resume Next
    MyStringVar1 = Application.WorksheetFunction.VLookup(Range("D2"), _
      Worksheets("Sheet1").Range("A:C"), 1, False)
    On Error GoTo 0
    If IsEmpty(MyStringVar1) Then
        MsgBox "Value not found!"
    End If

    Range("E2") = MyStringVar1

End Sub

By adding a method on prototype of array you can get random values easly.

In this example you can get single or multiple random values from array.

You can run to test code by clicking snippet button.

Array.prototype.random = function(n){
  if(n&&n>1){
    const a = [];
    for(let i = 0;i<n;i++){
      a.push(this[Math.floor(Math.random()*this.length)]);
    }
    return a;
  } else {
    return this[Math.floor(Math.random()*this.length)];
  }
}

const mySampleArray =  ['a','b','c','d','e','f','g','h'];

mySampleArray.random(); // return any random value etc. 'a', 'b'
mySampleArray.random(3); //retun an array with random values etc: ['b','f','a'] , ['d','b','d']

alert(mySampleArray.random());
alert(mySampleArray.random(3));

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

I'm on windows and had the same issue.

I used the below code :

install.packages("devtools", type = "win.binary")

Then library(devtools) worked for me.

You can try this code to get HTTP status code from WebException. It works in Silverlight too because SL does not have WebExceptionStatus.ProtocolError defined.

HttpStatusCode GetHttpStatusCode(WebException we)
{
    if (we.Response is HttpWebResponse)
    {
        HttpWebResponse response = (HttpWebResponse)we.Response;
        return response.StatusCode;
    }
    return null;
}

In onResume() change this line

items = dbHelper.getItems(); //reload the items from database

to

items.addAll(dbHelper.getItems()); //reload the items from database

The problem is that you're never telling your adapter about the new items list. If you don't want to pass a new list to your adapter (as it seems you don't), then just use items.addAll after your clear(). This will ensure you are modifying the same list that the adapter has a reference to.

I've recently done it slightly different to some of the examples above so thought I'd share, albeit very late!

Firstly the HTML, note there is only one class within the header:

<body>

<header class="GreyHeader">
</header>


</body>

And the CSS:

body {
height: 3000px;
}

.GreyHeader{
height: 200px; 
background-color: rgba(107,107,107,0.66);
position: fixed;
top:200;
width: 100%;

}

.FireBrickRed {
height: 100px;
background-color: #b22222;
position: fixed;
top:200;
width: 100%;
}

.transition {
  -webkit-transition: height 2s; /* For Safari 3.1 to 6.0 */
  transition: height 2s;
}

The html uses only the class .greyHeader but within the CSS I have created another class to call once the scroll has reached a certain point from the top:

$(function() {
    var header = $(".GreyHeader");
    $(window).scroll(function() {    
        var scroll = $(window).scrollTop();

        if (scroll >= 500) {
            header.removeClass('GreyHeader').addClass("FireBrickRed ");
            header.addClass("transition");
        } else {
            header.removeClass("FireBrickRed ").addClass('GreyHeader');
            header.addClass("transition");
        }
    });
});

You may be calling fragmentManager.popBackStackImmediate(); when activity is paused. Activity is not finished but is paused and not on foreground. You need to check whether activity is paused or not before popBackStackImmediate().

The answers here are worth a try, but you should also review your code. Specifically have a read of Polyfun's answer here: How to get rid of deadlock in a SQL Server 2005 and C# application?

It explains the concurrency issue, and how the usage of "with (updlock)" in your queries might correct your deadlock situation - depending really on exactly what your code is doing. If your code does follow this pattern, this is likely a better fix to make, before resorting to dirty reads, etc.

That is an HTTP header. You would configure your webserver or webapp to send this header ideally. Perhaps in htaccess or PHP.

Alternatively you might be able to use

<head>...<meta http-equiv="Access-Control-Allow-Origin" content="*">...</head>

I do not know if that would work. Not all HTTP headers can be configured directly in the HTML.

This works as an alternative to many HTTP headers, but see @EricLaw's comment below. This particular header is different.

Caveat

This answer is strictly about how to set headers. I do not know anything about allowing cross domain requests.

About HTTP Headers

Every request and response has headers. The browser sends this to the webserver

GET /index.htm HTTP/1.1

Then the headers

Host: www.example.com
User-Agent: (Browser/OS name and version information)
.. Additional headers indicating supported compression types and content types and other info

Then the server sends a response

Content-type: text/html
Content-length: (number of bytes in file (optional))
Date: (server clock)
Server: (Webserver name and version information)

Additional headers can be configured for example Cache-Control, it all depends on your language (PHP, CGI, Java, htaccess) and webserver (Apache, etc).

Starting from SQL Server 2016 a new way for sharing information in session is introduced via the SESSION_CONTEXT and sp_set_session_context.

You can use them as alternative of CONTEXT_INFO() which persist only a binary value limited to 128 bytes. Also, the user can rewrite the value anytime and it's not very good to use it for security checks.

The following issues are resolved using the new utils. You can store the data in more user-friendly format:

EXEC sp_set_session_context 'language', 'English';  
SELECT SESSION_CONTEXT(N'language');

Also, we can mark it as read-only:

EXEC sp_set_session_context 'user_id', 4, @read_only = 1;  

If you try to modify a read-only session context you will get something like this:

Msg 15664, Level 16, State 1, Procedure sp_set_session_context, Line 10 Cannot set key 'user_id' in the session context. The key has been set as read_only for this session.

Exporting without default means it's a "named export". You can have multiple named exports in a single file. So if you do this,

class Template {}
class AnotherTemplate {}

export { Template, AnotherTemplate }

then you have to import these exports using their exact names. So to use these components in another file you'd have to do,

import {Template, AnotherTemplate} from './components/templates'

Alternatively if you export as the default export like this,

export default class Template {}

Then in another file you import the default export without using the {}, like this,

import Template from './components/templates'

There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.

You're free to rename the default export as you import it,

import TheTemplate from './components/templates'

And you can import default and named exports at the same time,

import Template,{AnotherTemplate} from './components/templates'

A self contained solution in iOS 10, Swift 3 :

private func callNumber(phoneNumber:String) {

  if let phoneCallURL = URL(string: "tel://\(phoneNumber)") {

    let application:UIApplication = UIApplication.shared
    if (application.canOpenURL(phoneCallURL)) {
        application.open(phoneCallURL, options: [:], completionHandler: nil)
    }
  }
}

You should be able to use callNumber("7178881234") to make a call.

try to run the code below

- (void)viewDidLoad {
    [super viewDidLoad];
    UIWindow *w = [[UIApplication sharedApplication] keyWindow];
    UIView *v = [w.subviews objectAtIndex:0];

    NSLog(@"%@", NSStringFromCGRect(v.frame));
    NSLog(@"%@", NSStringFromCGRect(v.bounds));
}

the output of this code is:

case device orientation is Portrait

{{0, 0}, {768, 1024}}
{{0, 0}, {768, 1024}}

case device orientation is Landscape

{{0, 0}, {768, 1024}}
{{0, 0}, {1024, 768}}

obviously, you can see the difference between frame and bounds

The second parameter must be a URI, not a domain name. i.e.

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, "http://api.foursquare.com/", username, password)

You can use inline css :
<td style = "text-align: center;">

If you care about XSS then you should use <?= htmlspecialchars(…) ?> most of the time, so a short tag doesn't make a big difference.

Even if you shorten echo htmlspecialchars() to h(), it's still a problem that you have to remember to add it almost every time (and trying to keep track which data is pre-escaped, which is unescaped-but-harmless only makes mistakes more likely).

I use a templating engine that is secure by default and writes <?php tags for me.

To do this in t-sql, you can use the following system stored procedures to schedule a daily job. This example schedules daily at 1:00 AM. See Microsoft help for details on syntax of the individual stored procedures and valid range of parameters.

you can use g++ --std=c++0x example.cpp -o example

In my case, I solved this by following these two steps

1. Go to android studio preferences -> other settings -> kotlin compiler -> set Target JVM version = 1.8 
   if it doesn't work then go to the second option.

2. In your module-level build.gradle file add 
   compileOptions {
        sourceCompatibility = 1.8
        targetCompatibility = 1.8
    }
    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
        kotlinOptions {
            jvmTarget = "1.8"
        }
    }

The following snippet is used to take screenshot :

UIGraphicsBeginImageContext(self.muUIView.bounds.size);

[myUIView.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage *screenShot = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Use renderInContext: method instead of drawInContext: method

renderInContext: method renders the receiver and its sublayers into current context. This method renders directly from the layer tree.

Unfortunately, it the Developer Tools in Chrome seem to be unable to "stop on all errors", as Firebug does.

For those who are looking to combine 2 color images into one, this is a slight mod on Andrey's answer which worked for me :

img1 = cv2.imread(imageFile1)
img2 = cv2.imread(imageFile2)

h1, w1 = img1.shape[:2]
h2, w2 = img2.shape[:2]

#create empty matrix
vis = np.zeros((max(h1, h2), w1+w2,3), np.uint8)

#combine 2 images
vis[:h1, :w1,:3] = img1
vis[:h2, w1:w1+w2,:3] = img2

What worked for me is what others here have already said:

Don't show/hide elements on hover or mousemove (which is the event in my case).

Here's what Apple says (https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html):

A clickable element is a link, form element, image map area, or any other element with mousemove, mousedown, mouseup, or onclick handlers

If the user taps a clickable element, events arrive in this order: mouseover, mousemove, mousedown, mouseup, and click. Also, if the contents of the page changes on the mousemove event, no subsequent events in the sequence are sent. This behavior allows the user to tap in the new content.

So, you could use @woop's solution: detect the userAgent, check if it's and iOS device and then bind the event. I ended up using this technique because it suits my needs and it makes more sense do not bind hover events when you don't want it.

But... if you don't wanna mess with userAgents and still hide/show elements on hover/mousemove, i found out you can do so by using native javascript, like this:

$("body").on("mouseover", function() {
       document.getElementsByTagName("my-class")[0].style.display = 'block'; //show element
       document.querySelector(".my-selector div").style.display = 'none'; // hide element
});

This will work on the Desktop version and will do nothing on the mobile version.

And for a little more compatibility...

$("body").on("mouseover", function() {
   if (document.getElementsByTagName && document.querySelector) { // check compatibility
       document.getElementsByTagName("my-class")[0].style.display = 'block'; //show element
       document.querySelector(".my-selector div").style.display = 'none'; // hide element
    } else {
        $(".my-class").show();
        $(".my-selector div").hide();
    }
});

You have 2 options, and I am not sure if I am a fan of either of them, but that is my opinion. You may feel differently:

Option 1: Force the function to run.

A function in a cell does not run unless it references a cell that has changed. Changing a sheet name does not trigger any functions in the spreadsheet. But we can force the function to run by passing a range to it and whenever an item in that range changes, the function will trigger.

You can use the below script to create a custom function which will retrieve the name:

function mySheetName() {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  return key;
}

and in the cell place the following:

=mySheetName(A1:Z)

Now if any value in a cell in that passed range changes the script will run. This takes a second to run the script and sets a message in the cell each time any value is changed so this could become annoying very quickly. As already mentioned, it also requires a change in the range to cause it to trigger, so not really helpful on a fairly static file.

Option 2: Use the OnChange Event

While the run time feels better than the above option, and this does not depend on a value changing in the spreadsheet's cells, I do not like this because it forces where the name goes. You could use a Utilities sheet to define this location in various sheets if you wish. Below is the basic idea and may get you started if you like this option.

The OnChange event is triggered when the sheet name is changed. You can make the code below more sophisticated to check for errors, check the sheet ID to only work on a given sheet, etc. The basic code, however, is:

function setSheetName(e) {
  var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
  SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange('K1').setValue(key);
}

Once you have saved the code, in the script editor set the Current Project's On Change Trigger to this function. It will write the sheet name to cell K1 on any change event. To set the trigger, select Current project's triggers under the Edit menu.

You could try something like:

char ch;
fstream fin("file", fstream::in);
while (fin >> noskipws >> ch) {
    cout << ch; // Or whatever
}

the documentation has explained

• One difference is that interfaces create a new name that is used everywhere. Type aliases don’t create a new name — for instance, error messages won’t use the alias name.in older versions of TypeScript, type aliases couldn’t be extended or implemented from (nor could they extend/implement other types). As of version 2.7, type aliases can be extended by creating a new intersection type
• On the other hand, if you can’t express some shape with an interface and you need to use a union or tuple type, type aliases are usually the way to go.

Interfaces vs. Type Aliases

Specifically, this is not rounding your result, it's truncating toward zero. So if you divide -3/2, you'll get -1 and not -2. Welcome to integral math! Back before CPUs could do floating point operations or the advent of math co-processors, we did everything with integral math. Even though there were libraries for floating point math, they were too expensive (in CPU instructions) for general purpose, so we used a 16 bit value for the whole portion of a number and another 16 value for the fraction.

EDIT: my answer makes me think of the classic old man saying "when I was your age..."

This is the normal behavior and the reason is that your sqlCommandHandlerService.persist method needs a TX when being executed (because it is marked with @Transactional annotation). But when it is called inside processNextRegistrationMessage, because there is a TX available, the container doesn't create a new one and uses existing TX. So if any exception occurs in sqlCommandHandlerService.persist method, it causes TX to be set to rollBackOnly (even if you catch the exception in the caller and ignore it).

To overcome this you can use propagation levels for transactions. Have a look at this to find out which propagation best suits your requirements.

Update; Read this!

Well after a colleague came to me with a couple of questions about a similar situation, I feel this needs a bit of clarification.
Although propagations solve such issues, you should be VERY careful about using them and do not use them unless you ABSOLUTELY understand what they mean and how they work. You may end up persisting some data and rolling back some others where you don't expect them to work that way and things can go horribly wrong.

Program and Startup class

.NET Core 2.x

You don't need to new IConfiguration in the Startup constructor. Its implementation will be injected by the DI system.

// Program.cs
public class Program
{
    public static void Main(string[] args)
    {
        BuildWebHost(args).Run();
    }

    public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .Build();            
}

// Startup.cs
public class Startup
{
    public IHostingEnvironment HostingEnvironment { get; private set; }
    public IConfiguration Configuration { get; private set; }

    public Startup(IConfiguration configuration, IHostingEnvironment env)
    {
        this.HostingEnvironment = env;
        this.Configuration = configuration;
    }
}

.NET Core 1.x

You need to tell Startup to load the appsettings files.

// Program.cs
public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .UseApplicationInsights()
            .Build();

        host.Run();
    }
}

//Startup.cs
public class Startup
{
    public IConfigurationRoot Configuration { get; private set; }

    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
            .AddEnvironmentVariables();

        this.Configuration = builder.Build();
    }
    ...
}

Getting Values

There are many ways you can get the value you configure from the app settings:

• Simple way using ConfigurationBuilder.GetValue<T>
• Using Options Pattern

Let's say your appsettings.json looks like this:

{
    "ConnectionStrings": {
        ...
    },
    "AppIdentitySettings": {
        "User": {
            "RequireUniqueEmail": true
        },
        "Password": {
            "RequiredLength": 6,
            "RequireLowercase": true,
            "RequireUppercase": true,
            "RequireDigit": true,
            "RequireNonAlphanumeric": true
        },
        "Lockout": {
            "AllowedForNewUsers": true,
            "DefaultLockoutTimeSpanInMins": 30,
            "MaxFailedAccessAttempts": 5
        }
    },
    "Recaptcha": { 
        ...
    },
    ...
}

Simple Way

You can inject the whole configuration into the constructor of your controller/class (via IConfiguration) and get the value you want with a specified key:

public class AccountController : Controller
{
    private readonly IConfiguration _config;

    public AccountController(IConfiguration config)
    {
        _config = config;
    }

    [AllowAnonymous]
    public IActionResult ResetPassword(int userId, string code)
    {
        var vm = new ResetPasswordViewModel
        {
            PasswordRequiredLength = _config.GetValue<int>(
                "AppIdentitySettings:Password:RequiredLength"),
            RequireUppercase = _config.GetValue<bool>(
                "AppIdentitySettings:Password:RequireUppercase")
        };

        return View(vm);
    }
}

Options Pattern

The ConfigurationBuilder.GetValue<T> works great if you only need one or two values from the app settings. But if you want to get multiple values from the app settings, or you don't want to hard code those key strings in multiple places, it might be easier to use Options Pattern. The options pattern uses classes to represent the hierarchy/structure.

To use options pattern:

1. Define classes to represent the structure
2. Register the configuration instance which those classes bind against
3. Inject IOptions<T> into the constructor of the controller/class you want to get values on

1. Define configuration classes to represent the structure

You can define classes with properties that need to exactly match the keys in your app settings. The name of the class does't have to match the name of the section in the app settings:

public class AppIdentitySettings
{
    public UserSettings User { get; set; }
    public PasswordSettings Password { get; set; }
    public LockoutSettings Lockout { get; set; }
}

public class UserSettings
{
    public bool RequireUniqueEmail { get; set; }
}

public class PasswordSettings
{
    public int RequiredLength { get; set; }
    public bool RequireLowercase { get; set; }
    public bool RequireUppercase { get; set; }
    public bool RequireDigit { get; set; }
    public bool RequireNonAlphanumeric { get; set; }
}

public class LockoutSettings
{
    public bool AllowedForNewUsers { get; set; }
    public int DefaultLockoutTimeSpanInMins { get; set; }
    public int MaxFailedAccessAttempts { get; set; }
}

2. Register the configuration instance

And then you need to register this configuration instance in ConfigureServices() in the start up:

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
...

namespace DL.SO.UI.Web
{
    public class Startup
    {
        ...
        public void ConfigureServices(IServiceCollection services)
        {
            ...
            var identitySettingsSection = 
                _configuration.GetSection("AppIdentitySettings");
            services.Configure<AppIdentitySettings>(identitySettingsSection);
            ...
        }
        ...
    }
}

3. Inject IOptions

Lastly on the controller/class you want to get the values, you need to inject IOptions<AppIdentitySettings> through constructor:

public class AccountController : Controller
{
    private readonly AppIdentitySettings _appIdentitySettings;

    public AccountController(IOptions<AppIdentitySettings> appIdentitySettingsAccessor)
    {
        _appIdentitySettings = appIdentitySettingsAccessor.Value;
    }

    [AllowAnonymous]
    public IActionResult ResetPassword(int userId, string code)
    {
        var vm = new ResetPasswordViewModel
        {
            PasswordRequiredLength = _appIdentitySettings.Password.RequiredLength,
            RequireUppercase = _appIdentitySettings.Password.RequireUppercase
        };

        return View(vm);
    }
}

I've used most of the times the LIKE option and it works just fine. I just like to share one of my latest experiences where I used INSTR function. Regardless of the reasons that made me consider this options, what's important here is that the use is similar: instr(A, 'text 1') > 0 or instr(A, 'text 2') > 0 Another option could be: (instr(A, 'text 1') + instr(A, 'text 2')) > 0

I'd go with the LIKE '%text1%' OR LIKE '%text2%' option... if not hope this other option helps

You could try this:

git reset --hard HEAD
git pull

(from How do I force "git pull" to overwrite local files?)

Another idea would be to delete the entire git and make a new clone.

You can also have a look at FLTK (C++ and not plain C though)

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Here are some quickstart screencasts

[Happy New Year!]

If you use XHTML, for some reason, note that XHTML 1.0 C 4 says: “Use external scripts if your script uses < or & or ]]> or --.” That is, don’t embed script code inside a script element but put it into a separate JavaScript file and refer to it with <script src="foo.js"></script>.

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.

First:

x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId

Second:

(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) || 
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)

The call to the lambda would throw an exception for any x where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.

Edit after Comment to Question

If your original object is not a List<T>, then we have no way of knowing what the return type of FindAll() is, and whether or not this implements the IQueryable interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>> but anonymous delegates cannot, then you may be using the implementation of IQueryable when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.

This would also explain why your lambda is not causing a NullReferenceException. If you were to pass that lambda expression to something that implements IEnumerable<T> but not IQueryable<T>, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException the first time it encountered an object where ID was not equal to the target and the parent or grandparent was null.

Added 3/16/2011 8:29AM EDT

Consider the following simple example:

IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>

var anonymousMethod =  source.Where(delegate(MyObject o) { return o.Name == "Adam"; });    
var expressionLambda = source.Where(o => o.Name == "Adam");

These two methods produce entirely different results.

The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where extension method, where the entire contents of source will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:

public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
    foreach(MyObject item in dataSource)
    {
        if(predicate(item)) yield return item;
    }
}

The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE clause in the query; the entire result set would be brought back to the client and filtered there.

The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>> and uses the IQueryable<MyObject>.Where() extension method. This results in an object that is also typed as IQueryable<MyObject>. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.

An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable() before your call to Where in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T> like the anonymous delegate version, not IQueryable<T> like the lambda version currently does), and you'll get the exceptions as expected.

TL;DR Version

The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.

Thanks for all help at this issue. I'll post here my solution:

Please review.

(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)

Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT

Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).

Some OS-specific interfaces:

• Mac OS X: _NSGetExecutablePath() (man 3 dyld)
• Linux: readlink /proc/self/exe
• Solaris: getexecname()
• FreeBSD: sysctl CTL_KERN KERN_PROC KERN_PROC_PATHNAME -1
• FreeBSD if it has procfs: readlink /proc/curproc/file (FreeBSD doesn't have procfs by default)
• NetBSD: readlink /proc/curproc/exe
• DragonFly BSD: readlink /proc/curproc/file
• Windows: GetModuleFileName() with hModule = NULL

There are also third party libraries that can be used to get this information, such as whereami as mentioned in prideout's answer, or if you are using Qt, QCoreApplication::applicationFilePath() as mentioned in the comments.

The portable (but less reliable) method is to use argv[0]. Although it could be set to anything by the calling program, by convention it is set to either a path name of the executable or a name that was found using $PATH.

Some shells, including bash and ksh, set the environment variable "_" to the full path of the executable before it is executed. In that case you can use getenv("_") to get it. However this is unreliable because not all shells do this, and it could be set to anything or be left over from a parent process which did not change it before executing your program.

The best solution is to create a new branch with --orphan option as shown below

git checkout --orphan <branch name>

By this you will be able to create a new branch and directly checkout to the new branch. It will be a parentless branch.

By default the --orphan option doesn't remove the files in the working directory, so you can delete the working directory files by this:

git rm --cached -r

In details what the --orphan does:

--orphan <new_branch>
Create a new orphan branch, named <new_branch>, started from <start_point> and switch to it. The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits.

The index and the working tree are adjusted as if you had previously run git checkout <start_point>. This allows you to start a new history that records a set of paths similar to <start_point> by easily running git commit -a to make the root commit.

This can be useful when you want to publish the tree from a commit without exposing its full history. You might want to do this to publish an open source branch of a project whose current tree is "clean", but whose full history contains proprietary or otherwise encumbered bits of code.

If you want to start a disconnected history that records a set of paths that is totally different from the one of <start_point>, then you should clear the index and the working tree right after creating the orphan branch by running git rm -rf . from the top level of the working tree. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.

Edited: Just realized that I should specify that this works only if both of them exists. Otherwise the string is not considered quoted. Such scenario appeared for me when working with CSV files.

org.apache.commons.lang3.StringUtils.unwrap("\"abc\"", "\"")    = "abc"
org.apache.commons.lang3.StringUtils.unwrap("\"abc", "\"")    = "\"abc"
org.apache.commons.lang3.StringUtils.unwrap("abc\"", "\"")    = "abc\""

The new FirefoxDriver(binary, profile, timeSpan) has been obsolete.

You can now use new FirefoxDriver(FirefoxDriverService.CreateDefaultService(), FirefoxOptions options, TimeSpan commandTimeout) instead.

There is also a new FirefoxDriver(string geckoDriverDirectory, FirefoxOptions options, TimeSpan commandTimeout) and it does works. But it's undocumented, and you need to manually specify geckoDriverDirectory even though it's already in Path.

Not sure why, but in my case, the reason was because I was running Anaconda terminal instead of the CMD.

After I use CMD and update the path settings as mentioned by all comments above the issue solved on my side.

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

In jQuery I mostly use:

$("#element").trigger("change");

You might be better off if you just don't use nested classes. If you must nest, try this:

x = 1
class OuterClass:
    outer_var = x
    class InnerClass:
        inner_var = x

Or declare both classes before nesting them:

class OuterClass:
    outer_var = 1

class InnerClass:
    inner_var = OuterClass.outer_var

OuterClass.InnerClass = InnerClass

(After this you can del InnerClass if you need to.)

It's actually really easy. Highlight the DATE column and make sure that its set as date in Excel. Highlight everything you want to change, Then go to [DATA]>[SORT]>[COLUMN] and set sorting by date. Hope it helps.

MySQL stores DATETIME without timezone information. Let's say you store '2019-01-01 20:00:00' into a DATETIME field, when you retrieve that value you're expected to know what timezone it belongs to.

So in your case, when you store a value into a DATETIME field, make sure it is Tanzania time. Then when you get it out, it will be Tanzania time. Yay!

Now, the hairy question is: When I do an INSERT/UPDATE, how do I make sure the value is Tanzania time? Two cases:

1. You do INSERT INTO table (dateCreated) VALUES (CURRENT_TIMESTAMP or NOW()).

2. You do INSERT INTO table (dateCreated) VALUES (?), and specify the current time from your application code.

CASE #1

MySQL will take the current time, let's say that is '2019-01-01 20:00:00' Tanzania time. Then MySQL will convert it to UTC, which comes out to '2019-01-01 17:00:00', and store that value into the field.

So how do you get the Tanzania time, which is '20:00:00', to store into the field? It's not possible. Your code will need to expect UTC time when reading from this field.

CASE #2

It depends on what type of value you pass as ?. If you pass the string '2019-01-01 20:00:00', then good for you, that's exactly what will be stored to the DB. If you pass a Date object of some kind, then it'll depend on how the db driver interprets that Date object, and ultimate what 'YYYY-MM-DD HH:mm:ss' string it provides to MySQL for storage. The db driver's documentation should tell you.

Well yea, they are the same, but....!

window.location is not working on some Internet Explorer browsers.

i also want this to happen , so just pass the id of the element in the called function and used in my js file :

function copy(i,n)
{
 var range = document.createRange();
range.selectNode(document.getElementById(i));
window.getSelection().removeAllRanges();
window.getSelection().addRange(range); 
document.execCommand('copy');
window.getSelection().removeAllRanges();
document.getElementById(n).value = "Copied";
}

According to w3.org (note that this link is in the long-expired draft HTML 3.0 spec):

An unordered list typically is a bulleted list of items. HTML 3.0 gives you the ability to customise the bullets, to do without bullets and to wrap list items horizontally or vertically for multicolumn lists.

The opening list tag must be <UL>. It is followed by an optional list header (<LH>caption</LH>) and then by the first list item (<LI>). For example:

<UL>
  <LH>Table Fruit</LH>
  <LI>apples
  <LI>oranges
  <LI>bananas
</UL>

which could be rendered as:

Table Fruit

• apples
• oranges
• bananas

Note: Some legacy documents may include headers or plain text before the first LI element. Implementors of HTML 3.0 user agents are advised to cater for this possibility in order to handle badly formed legacy documents.

If anyone experiences the error for the same reason why I experience it, here's my solution:

if you had Html.AntiForgeryToken();

change it to @Html.AntiForgeryToken()

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

DECLARE @mylist TABLE (Id int)
INSERT INTO @mylist
SELECT id FROM (VALUES (1),(2),(3),(4),(5)) AS tbl(id)

SELECT * FROM Mytable WHERE theColumn IN (select id from @mylist)

bs := string(body) should be enough to give you a string.

From there, you can use it as a regular string.

A bit as in this thread:

var client http.Client
resp, err := client.Get(url)
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()

if resp.StatusCode == http.StatusOK {
    bodyBytes, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }
    bodyString := string(bodyBytes)
    log.Info(bodyString)
}

See also GoByExample.

As commented below (and in zzn's answer), this is a conversion (see spec).
See "How expensive is []byte(string)?" (reverse problem, but the same conclusion apply) where zzzz mentioned:

Some conversions are the same as a cast, like uint(myIntvar), which just reinterprets the bits in place.

Sonia adds:

Making a string out of a byte slice, definitely involves allocating the string on the heap. The immutability property forces this.
Sometimes you can optimize by doing as much work as possible with []byte and then creating a string at the end. The bytes.Buffer type is often useful.

There are three options, that you can use. -I is to exclude binary files in grep. Other are for line numbers and file names.

grep -I -n -H 


-I -- process a binary file as if it did not contain matching data; 
-n -- prefix each line of output with the 1-based line number within its input file
-H -- print the file name for each match

So this might be a way to run grep:

grep -InH your-word *

To simulate a dropped connection try

connection.destroy();

angle = Math.atan2(x,y)*180/Math.PI;

I have made a Formula for orienting angle into 0 to 360

angle + Math.ceil( -angle / 360 ) * 360;

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

For CentOS 7 and MariaDB 10.4, I had success with the following commands:

su -
systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --user=mysql"
systemctl restart mariadb
mysql -u root

flush privileges;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
flush privileges;
quit

systemctl unset-environment MYSQLD_OPTS
systemctl restart mariadb

Just do it Build -> Clean Project. I think this will solve your problem.

Well, it's too late to post an answer, but I feel my explanation will be easy to understand for beginners with Angular. The following is one of the examples that I give during my presentation.

Consider your angular Application as a building. A building can have N number of apartments in it. An apartment is considered as a module. An Apartment can then have N number of rooms which correspond to the building blocks of an Angular application named components.

Now each apartment (Module)` will have rooms (Components), lifts (Services) to enable larger movement in and out the apartments, wires (Pipes) to transform around and make it useful in the apartments.

You will also have places like swimming pool, tennis court which are being shared by all building residents. So these can be considered as components inside SharedModule.

Basically, the difference is as follows,

Follow my slides to understand the building blocks of an Angular application

Here is my session on Building Blocks of Angular for beginners

Yes, the first means "match all strings that start with a letter", the second means "match all strings that contain a non-letter". The caret ("^") is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.

In Python 3 this can be done in 2 steps:

1. Convert timestring to datetime object
2. Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds.

For example like this:

from datetime import datetime

dt_obj = datetime.strptime('20.12.2016 09:38:42,76',
                           '%d.%m.%Y %H:%M:%S,%f')
millisec = dt_obj.timestamp() * 1000

print(millisec)

Output:

1482223122760.0

strptime accepts your timestring and a format string as input. The timestring (first argument) specifies what you actually want to convert to a datetime object. The format string (second argument) specifies the actual format of the string that you have passed.

Here is the explanation of the format specifiers from the official documentation:

• %d - Day of the month as a zero-padded decimal number.
• %m - Month as a zero-padded decimal number.
• %Y - Year with century as a decimal number
• %H - Hour (24-hour clock) as a zero-padded decimal number.
• %M - Minute as a zero-padded decimal number.
• %S - Second as a zero-padded decimal number.
• %f - Microsecond as a decimal number, zero-padded on the left.

All you have to do is right click the .js file on Windows and press "Open with Command Prompt" OR Open cmd, copy the path to the folder containing your script, and run the command "cd [paste text here]". Then do "node example.js"

If the column is of type char then you need to append the value you are querying with spaces, please refer to this question here . This in addition to using COLLATE NOCASE or one of the other solutions (upper(), etc).

I'd use request for this:

request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))

Or if you don't need to save to a file first, and you just need to read the CSV into memory, you can do the following:

var request = require('request');
request.get('http://www.whatever.com/my.csv', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        var csv = body;
        // Continue with your processing here.
    }
});

etc.

download java-json.jar from Java2s then use the JSONArray constructor

List myList = new ArrayList<>();    
JSONArray jsonArray = new JSONArray(myList);
System.out.println(jsonArray);

alt is text that is displayed when the image can't be loaded or the user's browser doesn't support images (e.g. readers for blind people).

Try using something like lightbox:

http://www.lokeshdhakar.com/projects/lightbox2/

update: This library maybe better as its based on jQuery which you have said your using http://leandrovieira.com/projects/jquery/lightbox/

Typescript supports default parameters now:

https://www.typescriptlang.org/docs/handbook/functions.html

Also, adding a default value allows you to omit the type declaration, because it can be inferred from the default value:

function sayName(firstName: string, lastName = "Smith") {
  const name = firstName + ' ' + lastName;
  alert(name);
}

sayName('Bob');

You can use the workbook.get_worksheet_by_name() feature: https://xlsxwriter.readthedocs.io/workbook.html#get_worksheet_by_name

According to https://xlsxwriter.readthedocs.io/changes.html the feature has been added on May 13, 2016.

"Release 0.8.7 - May 13 2016

-Fix for issue when inserting read-only images on Windows. Issue #352.

-Added get_worksheet_by_name() method to allow the retrieval of a worksheet from a workbook via its name.

-Fixed issue where internal file creation and modification dates were in the local timezone instead of UTC."

You can simply use the Android's default HTML filter

    public String htmlToStringFilter(String textToFilter){

    return Html.fromHtml(textToFilter).toString();

    }

The above method will return the HTML filtered string for your input.

 for (Iterator<Tourist> itr = tourists.iterator(); itr.hasNext();) {
      if (itr.next() == null) { itr.remove(); }
 }

Request.Url.AbsoluteUri

This property does everything you need, all in one succinct call.

Consider the following:

https://www.example.com/createuser.php?name=Paul%20McCartney

In this hypothetical example, an HTML form - using the GET method - sends the "name" parameter to a PHP script that creates a new user account.

And the point I'm making with this example is that this GET parameter needs to be case-sensitive to preserve the capitalisation of "McCartney" (or, as another example, to preserve "Walter d'Isney", as there are other ways for names to break the usual capitalisation rules).

It's cases like these which guides the W3C recommendation that scheme and host are case insensitive, but everything after that is potentially case sensitive - and is left up to the server. Forcing case insensitivity by standard would make the above example incapable of preserving the case of user input passed as a GET query parameter.

But what I'd say is that though this is necessarily the letter of the law to accommodate such cases, the spirit of the law is that, where case is irrelevant, behave in a case insensitive way. The standards, though, can't tell you where case is irrelevant because, like the examples I've given, it's a context-dependent thing.

(e.g. an account username is probably best forced to case insensitivity - as "User123" and "user123" being different accounts could prove confusing - even if their real name, as above, is best left case sensitive.)

Sometimes it's relevant, most times it isn't. But it has to be left up to the server / web developer to decide these things - and can't be prescribed by standard - as only at that level could the context be known.

The scheme and host are case insensitive (which shows the standard's preference for case insensitivity, where it can be universally prescribed). The rest is left up to you to decide, as you understand the context better. But, as has been discussed, you probably should, in the spirit of the law, default to case insensitivity unless you have a good reason not to.

app.use() is intended for binding middleware to your application. The path is a "mount" or "prefix" path and limits the middleware to only apply to any paths requested that begin with it. It can even be used to embed another application:

// subapp.js
var express = require('express');
var app = modules.exports = express();
// ...

// server.js
var express = require('express');
var app = express();

app.use('/subapp', require('./subapp'));

// ...

By specifying / as a "mount" path, app.use() will respond to any path that starts with /, which are all of them and regardless of HTTP verb used:

• GET /
• PUT /foo
• POST /foo/bar
• etc.

app.get(), on the other hand, is part of Express' application routing and is intended for matching and handling a specific route when requested with the GET HTTP verb:

• GET /

And, the equivalent routing for your example of app.use() would actually be:

app.all(/^\/.*/, function (req, res) {
    res.send('Hello');
});

(Update: Attempting to better demonstrate the differences.)

The routing methods, including app.get(), are convenience methods that help you align responses to requests more precisely. They also add in support for features like parameters and next('route').

Within each app.get() is a call to app.use(), so you can certainly do all of this with app.use() directly. But, doing so will often require (probably unnecessarily) reimplementing various amounts of boilerplate code.

Examples:

• For simple, static routes:

  app.get('/', function (req, res) {
    // ...
  });
  

  vs.

  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    // ...
  });
  

• With multiple handlers for the same route:

  app.get('/', authorize('ADMIN'), function (req, res) {
    // ...
  });
  

  vs.

  const authorizeAdmin = authorize('ADMIN');
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET' || req.url !== '/')
      return next();
  
    authorizeAdmin(req, res, function (err) {
      if (err) return next(err);
  
      // ...
    });
  });
  

• With parameters:

  app.get('/item/:id', function (req, res) {
    let id = req.params.id;
    // ...
  });
  

  vs.

  const pathToRegExp = require('path-to-regexp');
  
  function prepareParams(matches, pathKeys, previousParams) {
    var params = previousParams || {};
  
    // TODO: support repeating keys...
    matches.slice(1).forEach(function (segment, index) {
      let { name } = pathKeys[index];
      params[name] = segment;
    });
  
    return params;
  }
  
  const itemIdKeys = [];
  const itemIdPattern = pathToRegExp('/item/:id', itemIdKeys);
  
  app.use('/', function (req, res, next) {
    if (req.method !== 'GET') return next();
  
    var urlMatch = itemIdPattern.exec(req.url);
    if (!urlMatch) return next();
  
    if (itemIdKeys && itemIdKeys.length)
      req.params = prepareParams(urlMatch, itemIdKeys, req.params);
  
    let id = req.params.id;
    // ...
  });

I used below code and it's working fine for me. :

let jsonText = "{\"userName\":\"Bhavsang\"}"
var dictonary:NSDictionary?
    
if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {
        
     do {
            dictonary =  try NSJSONSerialization.JSONObjectWithData(data, options: [.allowFragments]) as? [String:AnyObject]
        
            if let myDictionary = dictonary
              {
                  print(" User name is: \(myDictionary["userName"]!)")
              }
            } catch let error as NSError {
            
            print(error)
         }
}

    public bool FindAndKillProcess(string name)
    {
        //here we're going to get a list of all running processes on
        //the computer
        foreach (Process clsProcess in Process.GetProcesses()) {
            //now we're going to see if any of the running processes
            //match the currently running processes by using the StartsWith Method,
            //this prevents us from incluing the .EXE for the process we're looking for.
            //. Be sure to not
            //add the .exe to the name you provide, i.e: NOTEPAD,
            //not NOTEPAD.EXE or false is always returned even if
            //notepad is running
            if (clsProcess.ProcessName.StartsWith(name))
            {
                //since we found the proccess we now need to use the
                //Kill Method to kill the process. Remember, if you have
                //the process running more than once, say IE open 4
                //times the loop thr way it is now will close all 4,
                //if you want it to just close the first one it finds
                //then add a return; after the Kill
                try 
                {
                    clsProcess.Kill();
                }
                catch
                {
                    return false;
                }
                //process killed, return true
                return true;
            }
        }
        //process not found, return false
        return false;
    }

Synchronous functions are blocking while asynchronous functions are not. In synchronous functions, statements complete before the next statement is run. In this case, the program is evaluated exactly in order of the statements and execution of the program is paused if one of the statements take a very long time.

Asynchronous functions usually accept a callback as a parameter and execution continue on the next line immediately after the asynchronous function is invoked. The callback is only invoked when the asynchronous operation is complete and the call stack is empty. Heavy duty operations such as loading data from a web server or querying a database should be done asynchronously so that the main thread can continue executing other operations instead of blocking until that long operation to complete (in the case of browsers, the UI will freeze).

Orginal Posted on Github: Link

it is not possible to pragmatically get the permission... but ill suggest you to put that line of code in try{} catch{} which make your app unfortunately stop... and in catch body make a dialog box which will navigate the user to small tutorial to enable the draw over other apps permission... then on yes button click put this code...

 Intent callSettingIntent= new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
            startActivity(callSettingIntent);

this intent is to directly open the list of draw over other apps to manage permissions and then from here it is one click to the draw over other apps Permissions ... i know this is Not the answer you're looking for... but Im doing this in my apps...

There are much nicer ways to do it.

1. Install Nuget.Build package in you project that you want to pack. May need to close and re-open solution after install.

2. Install nuget via chocolatey - much nicer. Install chocolatey: https://chocolatey.org/, then run

   cinst Nuget.CommandLine

in your command prompt. This will install nuget and setup environment paths, so nuget is always available.

mysql_ functions have been removed from PHP 7. You can now use MySQLi or PDO.

MySQLi example:

mysqli_connect($mysql_hostname, $mysql_username, $mysql_password, $mysql_dbname);

mysqli_connect reference link

if you have a checkbox and you would like to fetch it's value ie true / false in any java file--

Use--

Context mContext;
boolean checkFlag;

checkFlag=PreferenceManager.getDefaultSharedPreferences(mContext).getBoolean(KEY,DEFAULT_VALUE);`

After adding this line of code, the issue will be fixed:

nltk.download('punkt')

You can also create the application.properties file manually.

SpringApplication will load properties from application.properties files in the following locations and add them to the Spring Environment:

• A /config subdirectory of the current directory.
• The current directory
• A classpath /config package
• The classpath root

The list is ordered by precedence (properties defined in locations higher in the list override those defined in lower locations). (From the Spring boot features external configuration doc page)

So just go ahead and create it

You can use the IPython.display.clear_output to clear the output as mentioned in cel's answer. I would add that for me the best solution was to use this combination of parameters to print without any "shakiness" of the notebook:

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print(i, flush=True)

What to me seems like the best option is the one suggested in the npm documentation, which is to first check where global node_modules are installed by default by running npm config get prefix. If you get, like I do on Trusty, /usr, you might want to change it to a folder that you can safely own without messing things up the way I did.

To do that, choose or create a new folder in your system. You may want to have it in your home directory or, like me, under /usr/local for consistency because I'm also a Mac user (I prefer not to need to look into different places depending on the machine I happen to be in front of). Another good reason to do that is the fact that the /usr/local folder is probably already in your PATH (unless you like to mess around with your PATH) but chances are your newly-created folder isn't and you'd need to add it to the PATH yourself on your .bash-profile or .bashrc file.

Long story short, I changed the default location of the global modules with npm config set prefix '/usr/local', created the folder /usr/local/lib/node_modules (it will be used by npm) and changed permissions for the folders used by npm with the command:

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Now you can globally install any module safely. Hope this helps!

A super quick and handy fix is to abuse Visual Studio's incredible intellisense by temporarily referencing the class somewhere.

Example:

System.Runtime.CompilerServices.ExtensionAttribute x = null;

When building or hovering the cursor over the line you can view the following error:

'System.Runtime.CompilerServices.ExtensionAttribute' exists in both 'C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll'

This tells you the two sources causing the conflict immediately.

System.Core.dll is the .dll file that you want to keep, so delete the other one.

I found mine sitting in the bin directory, but it may be elsewhere in the project.

As a matter of fact this is worth bearing in mind, because since the bin directory might not be included as part of the TFS change-set, it can explain why checking in your changes doesn't resolve the issue for other members of your team.

FragmentStatePagerAdapter = To accommodate a large number of fragments in ViewPager. As this adapter destroys the fragment when it is not visible to the user and only savedInstanceState of the fragment is kept for further use. This way a low amount of memory is used and a better performance is delivered in case of dynamic fragments.

tl;dr

Use ECMAScript 2015's Template String Literals, if applicable.

Explanation

There is no direct way to do it, as per ECMAScript 5 specifications, but ECMAScript 6 has template strings, which were also known as quasi-literals during the drafting of the spec. Use them like this:

> var n = 42;
undefined
> `foo${n}bar`
'foo42bar'

You can use any valid JavaScript expression inside the {}. For example:

> `foo${{name: 'Google'}.name}bar`
'fooGooglebar'
> `foo${1 + 3}bar`
'foo4bar'

The other important thing is, you don't have to worry about multi-line strings anymore. You can write them simply as

> `foo
...     bar`
'foo\n    bar'

Note: I used io.js v2.4.0 to evaluate all the template strings shown above. You can also use the latest Chrome to test the above shown examples.

Note: ES6 Specifications are now finalized, but have yet to be implemented by all major browsers.
According to the Mozilla Developer Network pages, this will be implemented for basic support starting in the following versions: Firefox 34, Chrome 41, Internet Explorer 12. If you're an Opera, Safari, or Internet Explorer user and are curious about this now, this test bed can be used to play around until everyone gets support for this.

It's called and and or in Python.

What about BASE58 encoding the URL? Like for example flickr does.

# note the missing lowercase L and the zero etc.
BASE58 = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ' 
url = ''
while node_id >= 58:
    div, mod = divmod(node_id, 58)
    url = BASE58[mod] + url
    node_id = int(div)

return 'http://short.com/%s' % BASE58[node_id] + url

Turning that back into a number isn't a big deal either.

Making something both a C identifier and a string

use setTag();

like this:

@Override    
public void onClick(View v) {     
    int tag = (Integer) v.getTag();     
    switch (tag) {     
    case 1:     
        System.out.println("button1 click");     
        break;     
    case 2:     
        System.out.println("button2 click");     
       break;   
    }     
}     

Or you can use simply preload="none" attribute to make VIDEO background visible. And you can use background-size: cover; here.

 video {
   background: transparent url('video-image.jpg') 50% 50% / cover no-repeat ;
 }

 <video preload="none" controls>
   <source src="movie.mp4" type="video/mp4">
   <source src="movie.ogg" type="video/ogg">

In the new ES2015 standard for JavaScript (formerly called ES6), objects can be created with computed keys: Object Initializer spec.

The syntax is:

var obj = {
  [myKey]: value,
}

If applied to the OP's scenario, it would turn into:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    return {
      [this.attr('name')]: this.attr('value'),
    };
  }) 

  callback(null, inputs);
}

Note: A transpiler is still required for browser compatiblity.

Using Babel or Google's traceur, it is possible to use this syntax today.

In earlier JavaScript specifications (ES5 and below), the key in an object literal is always interpreted literally, as a string.

To use a "dynamic" key, you have to use bracket notation:

var obj = {};
obj[myKey] = value;

In your case:

stuff = function (thing, callback) {
  var inputs  = $('div.quantity > input').map(function(){
    var key   = this.attr('name')
     ,  value = this.attr('value')
     ,  ret   = {};

     ret[key] = value;
     return ret;
  }) 

  callback(null, inputs);
}

if you want to keep the order as well then use this

let fruits = ["apple", "pear", "pear", "banana", "apple"] 
let orderedNoDuplicates = Array(NSOrderedSet(array: fruits).map({ $0 as! String }))

from collections import Counter
from scipy import stats

labels = [0.9, 0.09, 0.1]
stats.entropy(list(Counter(labels).keys()), base=2)

Make sure you are connecting with a USB and not a lightning cable. I had this problem trying to connect using a cord with lightning cables on both ends and it would not list the device. But switching to a USB to lightning cable worked.

Render Line Endings is a VS Code extension that is still actively maintained (as of Apr 2020):

https://marketplace.visualstudio.com/items?itemName=medo64.render-crlf

https://github.com/medo64/render-crlf/

It can be configured like this:

{
    "editor.renderWhitespace": "all",
    "code-eol.newlineCharacter": "¬",
    "code-eol.returnCharacter" : "¤",
    "code-eol.crlfCharacter"   : "¤¬",
}

and looks like this:

Read /usr/src/linux/Documentation/sysctl/kernel.txt.

[/proc/sys/kernel/]core_pattern is used to specify a core dumpfile pattern name.

• If the first character of the pattern is a '|', the kernel will treat the rest of the pattern as a command to run. The core dump will be written to the standard input of that program instead of to a file.

Instead of writing the core dump to disk, your system is configured to send it to the abrt program instead. Automated Bug Reporting Tool is possibly not as documented as it should be...

In any case, the quick answer is that you should be able to find your core file in /var/cache/abrt, where abrt stores it after being invoked. Similarly, other systems using Apport may squirrel away cores in /var/crash, and so on.

This post helped me today, but I had to experiment to do what I needed. Here is what I found.

Should you want to add more complex time periods, for example 1 year and 15 days, you can use

UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;

I found that using DATE_ADD doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now() rather than curdate().

For a use case like this, it may be useful to use a string constant so it can be marshaled into a JSON string. In the following example, []Base{A,C,G,T} would get marshaled to ["adenine","cytosine","guanine","thymine"].

type Base string

const (
    A Base = "adenine"
    C      = "cytosine"
    G      = "guanine"
    T      = "thymine"
)

When using iota, the values get marshaled into integers. In the following example, []Base{A,C,G,T} would get marshaled to [0,1,2,3].

type Base int

const (
    A Base = iota
    C
    G
    T
)

Here's an example comparing both approaches:

https://play.golang.org/p/VvkcWvv-Tvj

You can use the flip commands numpy.flipud() or numpy.fliplr() to get the indexes in descending order after sorting using the argsort command. Thats what I usually do.

private func convertDictToJson(dict : NSDictionary) -> NSDictionary?
{
    var jsonDict : NSDictionary!

    do {
        let jsonData = try JSONSerialization.data(withJSONObject:dict, options:[])
        let jsonDataString = String(data: jsonData, encoding: String.Encoding.utf8)!
        print("Post Request Params : \(jsonDataString)")
        jsonDict = [ParameterKey : jsonDataString]
        return jsonDict
    } catch {
        print("JSON serialization failed:  \(error)")
        jsonDict = nil
    }
    return jsonDict
}

This is a simple and maybe not the best solution, but it works.

On the line above the line you get your error, paste this:

This will set the current identity value to 0.

On inserting the next value, the identity value get incremented to 1.

I had the same problem and I fixed it by setting ALLOWED_HOSTS = ['*'] and to solve the problem with the static images you have to change the virtual paths in the environment configuration like this:

Virtual Path                 Directory

/static/                          /opt/python/current/app/yourpj/static/
/media/                        /opt/python/current/app/Nuevo/media/

I hope it helps you.

PD: sorry for my bad english.

Due to having some downtime at work, I decided to test the speeds of the different methods posted here.

These are the four methods I used.

static void Print1(string[] toPrint)
{
    foreach(string s in toPrint)
    {
        Console.Write(s);
    }
}

static void Print2(string[] toPrint)
{
    toPrint.ToList().ForEach(Console.Write);
}

static void Print3(string[] toPrint)
{
    Console.WriteLine(string.Join("", toPrint));
}

static void Print4(string[] toPrint)
{
    Array.ForEach(toPrint, Console.Write);
}

The results are as follows:

 Strings per trial: 10000
 Number of Trials: 100
 Total Time Taken to complete: 00:01:20.5004836
 Print1 Average: 484.37ms
 Print2 Average: 246.29ms
 Print3 Average: 70.57ms
 Print4 Average: 233.81ms

So Print3 is the fastest, because it only has one call to the Console.WriteLine which seems to be the main bottleneck for the speed of printing out an array. Print4 is slightly faster than Print2 and Print1 is the slowest of them all.

I think that Print4 is probably the most versatile of the 4 I tested, even though Print3 is faster.

If I made any errors, feel free to let me know / fix them on your own!

Converts bytes data to hex characters

@param bytes byte array to be converted to hex string
@return byte String in hex format

private static String bytesToHex(byte[] bytes) {
    char[] hexChars = new char[bytes.length * 2];
    int v;
    for (int j = 0; j < bytes.length; j++) {
        v = bytes[j] & 0xFF;
        hexChars[j * 2] = HEX_ARRAY[v >>> 4];
        hexChars[j * 2 + 1] = HEX_ARRAY[v & 0x0F];
    }
    return new String(hexChars);
}

You can simply do this:

timestamps.sort(reverse=True)

I did two things inspired by @OscarJovanny comment, with some hacks.

Step 1:

• Download icons file as svg from Here, as I only need only this icon from font awesome

Step 2:

<style>
ul {
    list-style-type: none;
    margin-left: 10px;
}

ul li {
    margin-bottom: 12px;
    margin-left: -10px;
    display: flex;
    align-items: center;
}

ul li::before {
    color: transparent;
    font-size: 1px;
    content: " ";
    margin-left: -1.3em;
    margin-right: 15px;
    padding: 10px;
    background-color: orange;
    -webkit-mask-image: url("./assets/img/check-circle-solid.svg");
    -webkit-mask-size: cover;

This is what solved it for us and these folks:

Our project started with Django 1.4, we went to 1.5 and then to 1.7. Our wsgi.py looked like this:

import os

from django.core.handlers.wsgi import WSGIHandler

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = WSGIHandler()

When I updated to the 1.7 style WSGI handler:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

Everything works now.

A simpler version of your code would be:

dict(zip(names, d.values()))

If you want to keep the same structure, you can change it to:

vlst = list(d.values())
{names[i]: vlst[i] for i in range(len(names))}

(You can just as easily put list(d.values()) inside the comprehension instead of vlst; it's just wasteful to do so since it would be re-generating the list every time).

String[] args = new String[]{"firstarg", "secondarg", "thirdarg"};

I have just tested Google Geocoder and got the same problem as you have. I noticed I only get the OVER_QUERY_LIMIT status once every 12 requests So I wait for 1 second (that's the minimum delay to wait) It slows down the application but less than waiting 1 second every request

info = getInfos(getLatLng(code)); //In here I call Google API
record(code, info);
generated++; 
if(generated%interval == 0) {
holdOn(delay); // Every x requests, I sleep for 1 second
}

With the basic holdOn method :

private void holdOn(long delay) {
        try {
            Thread.sleep(delay);
        } catch (InterruptedException ex) {
            // ignore
        }
    }

Hope it helps

I found that when I used the this callback function to ignore SSL certificates [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}

I always got the error message Invoke-WebRequest : The underlying connection was closed: An unexpected error occurred on a send. which sounds like the results you are having.

I found this forum post which lead me to the function below. I run this once inside the scope of my other code and it works for me.

                    return true;
                }
            }
        }

This is an addition to what prateek has answered.There seems to be a glitch in the code in IE so i decided to modify it a bit nothing fancy(just another condition)

$('document').ready(function() {
var lastScrollTop = 0;
$(window).scroll(function(event){
   var st = $(this).scrollTop();
   if (st > lastScrollTop){
       console.log("down")
   }
   else if(st == lastScrollTop)
   {
     //do nothing 
     //In IE this is an important condition because there seems to be some instances where the last scrollTop is equal to the new one
   }
   else {
      console.log("up")
   }
   lastScrollTop = st;
});});

import { HttpParams} from "@angular/common/http";
let Params= new HttpParams();
Params= Params.append('variableName1',variableValue1);
Params= Params.append('variableName2',variableValue2);

http.post<returnType>('api/yourApiLocation',variableValue0,{headers, params: Params})

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

The following should work:

cin.flush();

On some systems it's not available and then you can use:

cin.ignore(INT_MAX);

Add .idea/* to your exclusion list to prevent tracking of all .idea files, directories, and sub-resources.

In addition with what @Camilo Silva already mentioned, if you want to give free access to create databases, read, write databases, etc, but you don't want to create a root role, you can change the 3rd step with the following:

use admin
db.createUser(
  {
    user: "myUserAdmin",
    pwd: "abc123",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" }, 
             { role: "dbAdminAnyDatabase", db: "admin" }, 
             { role: "readWriteAnyDatabase", db: "admin" } ]
  }
)

In addition to the answers above.

I wrote following test.exe as console application

static void Main(string[] args) {
  Console.WriteLine(
    System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
  Console.WriteLine(
    System.Reflection.Assembly.GetEntryAssembly().Location);
  Console.WriteLine(
    System.Reflection.Assembly.GetExecutingAssembly().Location);
  Console.WriteLine(
    System.Reflection.Assembly.GetCallingAssembly().Location);
}

Then I compiled the project and renamed its output to the test2.exe file. The output lines were correct and the same.

But, if I start it in the Visual Studio, the result is:

d:\test2.vhost.exe

d:\test2.exe

d:\test2.exe

C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll

The ReSharper plug-in to the Visual Studio has underlined the

System.Diagnostics.Process.GetCurrentProcess().MainModule

as possible System.NullReferenceException. If you look into documentation of the MainModule you will find that this property can throw also NotSupportedException, PlatformNotSupportedException and InvalidOperationException.

The GetEntryAssembly method is also not 100% "safe". MSDN:

The GetEntryAssembly method can return null when a managed assembly has been loaded from an unmanaged application. For example, if an unmanaged application creates an instance of a COM component written in C#, a call to the GetEntryAssembly method from the C# component returns null, because the entry point for the process was unmanaged code rather than a managed assembly.

For my solutions, I prefer the Assembly.GetEntryAssembly().Location.

More interest is if need to solve the problem for the virtualization. For example, we have a project, where we use a Xenocode Postbuild to link the .net code into one executable. This executable must be renamed. So all the methods above didn't work, because they only gets the information for the original assembly or inner process.

The only solution I found is

var location = System.Reflection.Assembly.GetEntryAssembly().Location;
var directory = System.IO.Path.GetDirectoryName(location);
var file = System.IO.Path.Combine(directory, 
  System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");

Take a look at "Literal String Interpolation" https://www.python.org/dev/peps/pep-0498/

I found it through the http://www.malemburg.com/

In each pass through while loop r/c iterator increases and new row/cell object from collection is assigned to row/cell variables. When there's no more rows/cells in collection, false is assigned to row/cell variable and iteration through while loop stops (exits).

The iPhoneOS does capture onscroll events, except not the way you may expect.

One-finger panning doesn’t generate any events until the user stops panning—an onscroll event is generated when the page stops moving and redraws—as shown in Figure 6-1.

Similarly, scroll with 2 fingers fires onscroll only after you've stopped scrolling.

The usual way of installing the handler works e.g.

window.addEventListener('scroll', function() { alert("Scrolled"); });
// or
$(window).scroll(function() { alert("Scrolled"); });
// or
window.onscroll = function() { alert("Scrolled"); };
// etc

As well as the previous answers are you could always use the Pull attrib as well:

             <p>Some text here too.</p>
         </div>
     </div>
 </li>

try this

<iframe name="myIframe" id="myIframe" width="400px" height="400px" runat="server"></iframe>

Expose this iframe in the master page's codebehind:

public HtmlControl iframe
{
get
{
return this.myIframe;
}
}

Add the MasterType directive for the content page to strongly typed Master Page.

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits=_Default" Title="Untitled Page" %>
<%@ MasterType VirtualPath="~/MasterPage.master" %>

In code behind

protected void Page_Load(object sender, EventArgs e)
{
this.Master.iframe.Attributes.Add("src", "some.aspx");
}

If you want user to change between WindowStyle.SingleBorderWindow and WindowStyle.None at runtime you can bring this at code behind:

Make application fullscreen:

RootWindow.Visibility = Visibility.Collapsed;
RootWindow.WindowStyle = WindowStyle.None;
RootWindow.ResizeMode = ResizeMode.NoResize;
RootWindow.WindowState = WindowState.Maximized;
RootWindow.Topmost = true;
RootWindow.Visibility = Visibility.Visible;

Return to single border style:

RootWindow.WindowStyle = WindowStyle.SingleBorderWindow;
RootWindow.ResizeMode = ResizeMode.CanResize;
RootWindow.Topmost = false;

Note that without RootWindow.Visibility property your window will not cover start menu, however you can skip this step if you making application fullscreen once at startup.

There are vary solutions about this, but I couldn't find a whole thing. So I made my own solution for :

nicinfo

How to use :

NICInfoSummary* summary = [[[NICInfoSummary alloc] init] autorelease];

// en0 is for WiFi 
NICInfo* wifi_info = [summary findNICInfo:@"en0"];

// you can get mac address in 'XX-XX-XX-XX-XX-XX' form
NSString* mac_address = [wifi_info getMacAddressWithSeparator:@"-"];

// ip can be multiple
if(wifi_info.nicIPInfos.count > 0)
{
    NICIPInfo* ip_info = [wifi_info.nicIPInfos objectAtIndex:0];
    NSString* ip = ip_info.ip;
    NSString* netmask = ip_info.netmask;
    NSString* broadcast_ip = ip_info.broadcastIP;
}
else
{
    NSLog(@"WiFi not connected!");
}

Every even number is divisible by two, regardless of if it's a decimal (but the decimal, if present, must also be even). So you can use the % (modulo) operator, which divides the number on the left by the number on the right and returns the remainder...

boolean isEven(double num) { return ((num % 2) == 0); }

If you would like to execute the parent controller's parentmethod function inside a child controller, call it:

$scope.$parent.parentmethod();

I'm just learning this and what finally worked for me was to first make a table with three rows. Set the margin for the left and right rows to 50%. Then put a single row, fixed width table inside of the "table data" of the center "table row".

When I studied IT in college my prof. made it simple for me:

"A computer "program" and an "application" (a.k.a. 'app') are one-in-the-same. The only difference is a technical one. While both are the same, an 'application' is a computer program launched and dependent upon an operating system to execute."

Got it right on the exam.

So when you click on a word processor, for example, it is an application, as is that hidden file that runs the printer spooler launched only by the OS. The two programs depend on the OS, whereby the OS itself or your internal BIOS programming are not 'apps' in the technical sense as they communicate directly with the computer hardware itself.

Unless the definition has changed in the past few years, commercial entities like Microsoft and Apple are not using the terms properly, preferring sexy marketing by making the term 'apps' seem like something popular market and 'new', because a "computer program" sounds too 'nerdy'. :(

My workmates and I have different Gemfile.lock, because we use different platforms, windows and mac, and our server is linux.

We decide to remove Gemfile.lock in repo and create Gemfile.lock.server in git repo, just like database.yml. Then before deploy it on server, we copy Gemfile.lock.server to Gemfile.lock on server using cap deploy hook

Suppose you wanted to cast a String to a File (yes it does not make any sense), you cannot cast it directly because the File class is not a child and not a parent of the String class (and the compiler complains).

But you could cast your String to Object, because a String is an Object (Object is parent). Then you could cast this object to a File, because a File is an Object.

So all you operations are 'legal' from a typing point of view at compile time, but it does not mean that it will work at runtime !

File f = (File)(Object) "Stupid cast";

The compiler will allow this even if it does not make sense, but it will crash at runtime with this exception:

Exception in thread "main" java.lang.ClassCastException:
    java.lang.String cannot be cast to java.io.File

What sort of button, neither a Forms Control nor an ActiveX control should affect the used range.

It is a known problem that excel does not keep track of the used range very well. Any reference to the used range via VBA will reset the value to the current used range. So try running this sub procedure:

Sub ResetUsedRng()
    Application.ActiveSheet.UsedRange 
End Sub 

Failing that you may well have some formatting hanging round. Try clearing/deleting all the cells after your last row.

Regarding the above also see:

Excel Developer Tip

Another method to find the last used cell:

    Dim rLastCell As Range

    Set rLastCell = ActiveSheet.Cells.Find(What:="*", After:=.Cells(1, 1), LookIn:=xlFormulas, LookAt:= _
    xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=False)

Change the search direction to find the first used cell.

This depends on a lot of things, such as what is the size of the file, what is its type (text/binary) etc. Some time ago I benchmarked the following function against versions using streambuf iterators - it was about twice as fast:

unsigned int FileRead( std::istream & is, std::vector <char> & buff ) {
    is.read( &buff[0], buff.size() );
    return is.gcount();
}

void FileRead( std::ifstream & ifs, string & s ) {
    const unsigned int BUFSIZE = 64 * 1024; // reasoable sized buffer
    std::vector <char> buffer( BUFSIZE );

    while( unsigned int n = FileRead( ifs, buffer ) ) {
        s.append( &buffer[0], n );
    }
}

One line Swift 5.2

let date = String(DateFormatter.localizedString(from: NSDate() as Date, dateStyle: .medium, timeStyle: .short))

$location won't help you with external URLs, use the $window service instead:

$window.location.href = 'http://www.google.com';

Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.

Or you could use the array_reverse function.

Using bootstrap with a little bit of customization, the following seems to work for me:

I need 3 partitions in my container and I tried this:

CSS:

.row.content {height: 100%; width:100%; position: fixed; }
.sidenav {
  padding-top: 20px;
  border: 1px solid #cecece;
  height: 100%;
}
.midnav {
  padding: 0px;
}

HTML:

  <div class="container-fluid text-center"> 
    <div class="row content">
    <div class="col-md-2 sidenav text-left">Some content 1</div>
    <div class="col-md-9 midnav text-left">Some content 2</div>
    <div class="col-md-1 sidenav text-center">Some content 3</div>
    </div>
  </div>

import tensorflow as tf

print(tf.VERSION)

Adding on to @modiX answer, this is what works...DO NOT LEAVE THAT as empty

today.toLocaleDateString("default", {year: "numeric", month: "2-digit", day: "2-digit"})

f.write(plaintext)
f.write("\n".encode("utf-8"))

On BSD systems and Android you can also use fgetln:

#include <stdio.h>

char *
fgetln(FILE *stream, size_t *len);

Like so:

size_t line_len;
const char *line = fgetln(stdin, &line_len);

The line is not null terminated and contains \n (or whatever your platform is using) in the end. It becomes invalid after the next I/O operation on stream. You are allowed to modify the returned line buffer.

Swift version

A delegate is just a class that does some work for another class. Read the following code for a somewhat silly (but hopefully enlightening) Playground example that shows how this is done in Swift.

// A protocol is just a list of methods (and/or properties) that must
// be used by any class that adopts the protocol.
protocol OlderSiblingDelegate: class {
    // This protocol only defines one required method
    func getYourNiceOlderSiblingAGlassOfWater() -> String
}

class BossyBigBrother {
    
    // The delegate is the BossyBigBrother's slave. This position can 
    // be assigned later to whoever is available (and conforms to the 
    // protocol).
    weak var delegate: OlderSiblingDelegate?
    
    func tellSomebodyToGetMeSomeWater() -> String? {
        // The delegate is optional because there might not be anyone
        // nearby to boss around.
        return delegate?.getYourNiceOlderSiblingAGlassOfWater()
    }
}

// PoorLittleSister conforms to the OlderSiblingDelegate protocol
class PoorLittleSister: OlderSiblingDelegate {

    // This method is repquired by the protocol, but the protocol said
    // nothing about how it needs to be implemented.
    func getYourNiceOlderSiblingAGlassOfWater() -> String {
        return "Go get it yourself!"
    }
    
}

// initialize the classes
let bigBro = BossyBigBrother()
let lilSis = PoorLittleSister()

// Set the delegate 
// bigBro could boss around anyone who conforms to the 
// OlderSiblingDelegate protocol, but since lilSis is here, 
// she is the unlucky choice.
bigBro.delegate = lilSis

// Because the delegate is set, there is a class to do bigBro's work for him.
// bigBro tells lilSis to get him some water.
if let replyFromLilSis = bigBro.tellSomebodyToGetMeSomeWater() {
    print(replyFromLilSis) // "Go get it yourself!"
}

In actual practice, delegates are often used in the following situations

1. When a class needs to communicate some information to another class
2. When a class wants to allow another class to customize it

The classes don't need to know anything about each other beforehand except that the delegate class conforms to the required protocol.

I highly recommend reading the following two articles. They helped me understand delegates even better than the documentation did.

• What is Delegation? – A Swift Developer’s Guide
• How Delegation Works – A Swift Developer’s Guide

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.

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

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

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

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

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

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

Thank you very much! Finally I solved the blurred pixels problem with this code:

<canvas id="graph" width=326 height=240 style='width:326px;height:240px'></canvas>

With the addition of the 'half-pixel' does the trick to unblur lines.

Late simple example:

from os import path, getcwd, chdir

def print_my_path():
    print('cwd:     {}'.format(getcwd()))
    print('__file__:{}'.format(__file__))
    print('abspath: {}'.format(path.abspath(__file__)))

print_my_path()

chdir('..')

print_my_path()

Under Python-2.*, the second call incorrectly determines the path.abspath(__file__) based on the current directory:

cwd:     C:\codes\py
__file__:cwd_mayhem.py
abspath: C:\codes\py\cwd_mayhem.py
cwd:     C:\codes
__file__:cwd_mayhem.py
abspath: C:\codes\cwd_mayhem.py

As noted by @techtonik, in Python 3.4+, this will work fine since __file__ returns an absolute path.

document.location is a synonym for window.location that has been deprecated for almost as long as JavaScript has existed. Don't use it.

location is a structured object, with properties corresponding to the parts of the URL. location.href is the whole URL in a single string. Assigning a string to either is defined to cause the same kind of navigation, so take your pick.

I consider writing to location.href = something to be marginally better as it's slightly more explicit about what it's doing. You generally want to avoid just location = something as it looks misleadingly like a variable assignment. window.location = something is fine though.

These answers are a bit dated. Therefore I give you:

hash = JSON.parse string

Rails should automagically load the json module for you, so you don't need to add require 'json'.

Most probably your server socket is bound to the loopback IP address 127.0.0.1 instead of the "all IP addresses" symbolic IP 0.0.0.0 (note this is NOT a netmask). To confirm this, run sudo netstat -ntlp (If you are on linux) or netstat -an -f inet -p tcp | grep LISTEN (OSX) and check which IP your process is bound to (look for the line with ":3000"). If you see "127.0.0.1", that's the problem. Fix it by passing "0.0.0.0" to the listen call:

var app = connect().use(connect.static('public')).listen(3000, "0.0.0.0");

Use a regex: .

Match m = Regex.Match(text, @"(.+? .+?) ");
if (m.Success) {
    do_something_with(m.Groups[1].Value);
}

The only "big" difference between POST & GET (when using them with AJAX) is since GET is URL provided, they are limited in ther length (since URL arent infinite in length).
