For the sake of completeness, what you are trying to create is a "modal window".

Numerous JS solutions allow you to create them with ease, take the time to find the one which best suits your needs.

I have used Tinybox 2 for small projects : http://sandbox.scriptiny.com/tinybox2/

For eslint:

"editor.codeActionsOnSave": { "source.fixAll.eslint": true }

Here is a usable class based on what Constantin said:

        FastConcat<int> i = new FastConcat<int>();
        i.Add(new int[] { 0, 1, 2, 3, 4 });
        Console.WriteLine(i[0]);
        i.Add(new int[] { 5, 6, 7, 8, 9 });
        Console.WriteLine(i[4]);

        Console.WriteLine("Enumerator:");
        foreach (int val in i)
            Console.WriteLine(val);

        Console.ReadLine();
    }
}

    LinkedList<T[]> _items = new LinkedList<T[]>();
    int _count;

    public int Count

        if (items.Length == 0)
            return;

        _items.AddLast(items);
        _count += items.Length;
    }

    private T[] GetItemIndex(int realIndex, out int offset)
    {
        offset = 0; // Offset that needs to be applied to realIndex.
        int currentStart = 0; // Current index start.

        foreach (T[] items in _items)
        {
            currentStart += items.Length;
            if (currentStart > realIndex)
                return items;
            offset = currentStart;
        }
        return null;
    }

        }
        set
        {
            int offset;
            T[] i = GetItemIndex(index, out offset);
            i[index - offset] = value;
        }
    }

    #region IEnumerable<T> Members

    public IEnumerator<T> GetEnumerator()
    {
        foreach (T[] items in _items)
            foreach (T item in items)
                yield return item;
    }

    #endregion

    #region IEnumerable Members

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()

BUILD_NUMBER is the current build number. You can use it in the command you execute for the job, or just use it in the script your job executes.

See the Jenkins documentation for the full list of available environment variables. The list is also available from within your Jenkins instance at http://hostname/jenkins/env-vars.html.

Use the DecimalFormat class to format the double

Well for Ubuntu 14.04 I was getting that error just for mcrypt:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/mcrypt.ini' - /usr/lib/php5/20121212/mcrypt.ini: cannot open shared object file: No such file or directory in Unknown on line 0

If you have a closer look at the error, php is looking for mcrypt.ini and not for mcrypt.so at that location. I just copy mcrypt.so to mcrypt.ini and that's it, the warning is gone and the extension now is properly installed. It might look a bit dirty but it worked!

Read the InputStream of a file and write it to ServletOutputStream for sending binary data to the client.

• Local file You can read a file directly using FileInputStream('path/image.png').
• Mongo DataBase file's you can get InputStream using GridFS.

@WebServlet("/files/URLStream")
public class URLStream extends HttpServlet {
    private static final long serialVersionUID = 1L;

    public URLStream() {
        super();
    }

    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        File source = new File("D:\\SVN_Commit.PNG");
        long start = System.nanoTime();

        InputStream image = new FileInputStream(source);

        /*String fileID = request.getParameter("id");
        System.out.println("Requested File ID : "+fileID);
        // Mongo DB GridFS - https://stackoverflow.com/a/33544285/5081877
        image = outputImageFile.getInputStream();*/

        if( image != null ) {
            BufferedInputStream bin = null;
            BufferedOutputStream bout = null;
            ServletOutputStream sos = response.getOutputStream();
            try {
                bin = new BufferedInputStream( image );
                bout = new BufferedOutputStream( sos );
                int ch =0; ;
                while((ch=bin.read())!=-1) {
                    bout.write(ch);
                }
            } finally {
                bin.close();
                image.close();
                bout.close();
                sos.close();
            }

        } else {
            PrintWriter writer = response.getWriter();
            writer.append("Something went wrong with your request.");
            System.out.println("Image not available.");
        }
        System.out.println("Time taken by Stream Copy = "+(System.nanoTime()-start));
    }
}

Stack Implementation in Java

  class stack
  {  private int top;
     private int[] element;
      stack()
      {element=new int[10];
      top=-1;
      }
      void push(int item)
      {top++;
      if(top==9)
          System.out.println("Overflow");
      else
              {
               top++;
      element[top]=item;

      }

      void pop()
      {if(top==-1)
          System.out.println("Underflow");
      else  
      top--;
      }
      void display()
      {
          System.out.println("\nTop="+top+"\nElement="+element[top]);
      }

      public static void main(String args[])
      {
        stack s1=new stack();
        s1.push(10);
        s1.display();
        s1.push(20);
        s1.display();
        s1.push(30);
        s1.display();
        s1.pop();
        s1.display();
      }

  }

Output

Top=0
Element=10
Top=1
Element=20
Top=2
Element=30
Top=1
Element=20

Put the value of a human-readable string into a .NET DateTime with code like this:

DateTime.ParseExact("April 16, 2011 4:27 pm", "MMMM d, yyyy h:mm tt", null);

I know this is a old thread but I've just had to do this. While the other approaches here work, I wanted an easy way to be able to affect a lot of calls to string.format. So adding the Math.Truncate to all the calls to wasn't really a good option. Also as some of the formatting is stored in a database, it made it even worse.

Thus, I made a custom format provider which would allow me to add truncation to the formatting string, eg:

string.format(new FormatProvider(), "{0:T}", 1.1299); // 1.12
string.format(new FormatProvider(), "{0:T(3)", 1.12399); // 1.123
string.format(new FormatProvider(), "{0:T(1)0,000.0", 1000.9999); // 1,000.9

The implementation is pretty simple and is easily extendible to other requirements.

public class FormatProvider : IFormatProvider, ICustomFormatter
{
    public object GetFormat(Type formatType)
    {
        if (formatType == typeof (ICustomFormatter))
        {
            return this;
        }
        return null;
    }

    public string Format(string format, object arg, IFormatProvider formatProvider)
    {
        if (arg == null || arg.GetType() != typeof (double))
        {
            try
            {
                return HandleOtherFormats(format, arg);
            }
            catch (FormatException e)
            {
                throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
            }
        }

        if (format.StartsWith("T"))
        {
            int dp = 2;
            int idx = 1;
            if (format.Length > 1)
            {
                if (format[1] == '(')
                {
                    int closeIdx = format.IndexOf(')');
                    if (closeIdx > 0)
                    {
                        if (int.TryParse(format.Substring(2, closeIdx - 2), out dp))
                        {
                            idx = closeIdx + 1;
                        }
                    }
                    else
                    {
                        throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
                    }
                }
            }
            double mult = Math.Pow(10, dp);
            arg = Math.Truncate((double)arg * mult) / mult;
            format = format.Substring(idx);
        }

        try
        {
            return HandleOtherFormats(format, arg);
        }
        catch (FormatException e)
        {
            throw new FormatException(string.Format("The format of '{0}' is invalid.", format));
        }
    }

    private string HandleOtherFormats(string format, object arg)
    {
        if (arg is IFormattable)
        {
            return ((IFormattable) arg).ToString(format, CultureInfo.CurrentCulture);
        }
        return arg != null ? arg.ToString() : String.Empty;
    }
}

If you are moving branches to a new repo from an old one and do NOT have all the old repo branches local, you will need to track them first.

for remote in `git branch -r | grep -v '\->'`; do git branch --track $remote; done

Then add your new remote repo:

git remote add bb <path-to-new-repo>

Then you can push all using this command:

git push -u bb --all

Or you can configure the repo using the git config commands noted in the other responses here if you are not doing this one time or are only looking to move local branches.

The important point, the other responses only push all LOCAL branches. If the branches only exist on an alternate REMOTE repository they will not move without tracking them first. The for loop presented here will help with that.

This will get the name in the ng-repeat to come up seperate in the form validation.

<td>
    <input ng-model="r.QTY" class="span1" name="{{'QTY' + $index}}" ng-pattern="/^[\d]*\.?[\d]*$/" required/>
</td>

But I had trouble getting it to look up in its validation message so I had to use an ng-init to get it to resolve a variable as the object key.

<td>
    <input ng-model="r.QTY" class="span1" ng-init="name = 'QTY' + $index" name="{{name}}" ng-pattern="/^[\d]*\.?[\d]*$/" required/>
    <span class="alert-error" ng-show="form[name].$error.pattern"><strong>Requires a number.</strong></span>
    <span class="alert-error" ng-show="form[name].$error.required"><strong>*Required</strong></span> 

Reference the System.Web dll in your model and use System.Web.Caching.Cache

    public string[] GetNames()
    {
      string[] names = Cache["names"] as string[];
      if(names == null) //not in cache
      {
        names = DB.GetNames();
        Cache["names"] = names;
      }
      return names;
    }

A bit simplified but I guess that would work. This is not MVC specific and I have always used this method for caching data.

This happened to me because I was using:

app.datasource.url=jdbc:mysql://localhost/test

When I replaced url by jdbc-url then it worked:

app.datasource.jdbc-url=jdbc:mysql://localhost/test

• the simplest way to do that is using encoding/json package

just for example:

package main
import (
    "fmt"
    "encoding/json"
)

type MyAddress struct {
    House string
    School string
}
type Student struct {
    Id int64
    Name string
    Scores float32
    Address MyAddress
    Labels []string
}

func Test() {

    dict := make(map[string]interface{})
    dict["id"] = 201902181425       // int
    dict["name"] = "jackytse"       // string
    dict["scores"] = 123.456        // float
    dict["address"] = map[string]string{"house":"my house", "school":"my school"}   // map
    dict["labels"] = []string{"aries", "warmhearted", "frank"}      // slice

    jsonbody, err := json.Marshal(dict)
    if err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    student := Student{}
    if err := json.Unmarshal(jsonbody, &student); err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    fmt.Printf("%#v\n", student)
}

func main() {
    Test()
}

Another simple solution is to add jackson-databind dependency in POM.

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.1</version>
    </dependency>

Keep Rest of the code as it is.

There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:

HorizontalContentAlignment="Stretch"

... to force the contents of a control to stretch horizontally. Or you can say:

HorizontalAlignment="Stretch"

... to force the control itself to stretch horizontally to fill its parent.

In a project of our company we are using "rooms" approach and it's name is a combination of user ids of all users in a conversation as a unique identifier (our implementation is more like facebook messenger), example:

|id | name |1 | Scott |2 | Susan

"room" name will be "1-2" (ids are ordered Asc.) and on disconnect socket.io automatically cleans up the room

this way you send messages just to that room and only to online (connected) users (less packages sent throughout the server).

Change:

 data: JSON.stringify({ model: source })

To:

 data: {model: JSON.stringify(source)}

And in your controller you do this:

public void PartSourceAPI(string model)
{
       System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

   var result = js.Deserialize<PartSourceModel>(model);
}

If the url you use in jquery is /api/PartSourceAPI then the controller name must be api and the action(method) should be PartSourceAPI

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

This is probably the simplest way of doing it:

sed -r 's/\s+//g' filename > output
mv ouput filename

My answer below shows how to embed images using data URIs. This is useful for the web, but will not work reliably for most email clients. For email purposes be sure to read Shadow2531's answer.

Base-64 data is legal in an img tag and I believe your question is how to properly insert such an image tag.

You can use an online tool or a few lines of code to generate the base 64 string.

The syntax to source the image from inline data is:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO

var language = window.navigator.userLanguage || window.navigator.language;
alert(language); //works IE/SAFARI/CHROME/FF

window.navigator.userLanguage is IE only and it's the language set in Windows Control Panel - Regional Options and NOT browser language, but you could suppose that a user using a machine with Window Regional settings set to France is probably a French user.

navigator.language is FireFox and all other browser.

Some language code: 'it' = italy, 'en-US' = english US, etc.

As pointed out by rcoup and The WebMacheter in comments below, this workaround won't let you discriminate among English dialects when users are viewing website in browsers other than IE.

window.navigator.language (Chrome/FF/Safari) returns always browser language and not browser's preferred language, but: "it's pretty common for English speakers (gb, au, nz, etc) to have an en-us version of Firefox/Chrome/Safari." Hence window.navigator.language will still return en-US even if the user preferred language is en-GB.

While using simplified tags with AndroidX consider using HtmlCompat.fromHtml()

String s = "<b>Bolded text</b>, <i>italic text</i>, even <u>underlined</u>!"    
TextView tv = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);
tv.setText(HtmlCompat.fromHtml(s, FROM_HTML_MODE_LEGACY));

This would be a simpler approach

#over > img{
    display: block;
    margin:0 auto; 
}

System is a final class from the java.lang package.

out is a class variable of type PrintStream declared in the System class.

println is a method of the PrintStream class.

I found the following comparison helpful:

str(f1) == str(f2)

You can use a ComboBox with its ComboBoxStyle (appears as DropDownStyle in later versions) set to DropDownList. See: http://msdn.microsoft.com/en-us/library/system.windows.forms.comboboxstyle.aspx

Use 'subset'

DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA), z=c(NA, 33, 22))
subset(DF, !is.na(y))

If you have shell access you may use mysqldump to dump the content of database1.table1 and pipe it to mysql to database2. The problem here is that table1 is still table1.

mysqldump --user=user1 --password=password1 database1 table1 \
| mysql --user=user2 --password=password2 database2

Maybe you need to rename table1 to table2 with another query. On the other way you might use sed to change table1 to table2 between the to pipes.

mysqldump --user=user1 --password=password1 database1 table1 \
| sed -e 's/`table1`/`table2`/' \
| mysql --user=user2 --password=password2 database2

If table2 already exists, you might add the parameters to the first mysqldump which dont let create the table-creates.

mysqldump --no-create-info --no-create-db --user=user1 --password=password1 database1 table1 \
| sed -e 's/`table1`/`table2`/' \
| mysql --user=user2 --password=password2 database2

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

Once you have your date object constructed, here's a snippet for the conversion:

The function takes a UTC formatted Date object and format string.
You will need a Date.strftime prototype.

function UTCToLocalTimeString(d, format) {
    if (timeOffsetInHours == null) {
        timeOffsetInHours = (new Date().getTimezoneOffset()/60) * (-1);
    }
    d.setHours(d.getHours() + timeOffsetInHours);

    return d.strftime(format);
}

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

The question mentions Windows, and the accepted answer also works for Ubuntu, but for those who found this question coming from a Redhat flavor of Linux, this did the trick:

sudo yum install -y python-setuptools

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

I had the same problem and from the answers above and from what I understood what worked for me ultimately was:

1. Have a shebang line that invokes the intended script, for example,

   #!/bin/bash uses bash to execute the script

I have scripts with both kinds of shebang's. Because of this, using sh or . was not reliable, as it lead to a mis-execution (like when the script bails out having run incompletely)

The answer therefore, was

2. • Make sure the script has a shebang, so that there is no doubt about its intended handler.
   • chmod the .sh file so that it can be executed. (chmod +x file.sh)

   • Invoke it directly without any sh or .

     (./myscript.sh)

Hope this helps someone with similar question or problem.

Try this:

export PATH=/home/your_username/anaconda3/bin:$PATH
in ~/.bashrc

Then source ~/.bashrc This works for me for the same problem.

You can easily catch integer(0) with function identical(x,y)

x = integer(0)
identical(x, integer(0))
[1] TRUE

foo = function(x){identical(x, integer(0))}
foo(x)
[1] TRUE

foo(0)
[1] FALSE

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

<p th:text="|${bean.field} ! ${bean.field}|">Static content</p>

In SQL Server 2016 the wizard is a separate app. (Important: Excel wizard is only available in the 32-bit version of the wizard!). Use the MSDN page for instructions:

On the Start menu, point to All Programs, point toMicrosoft SQL Server , and then click Import and Export Data.
—or—
In SQL Server Data Tools (SSDT), right-click the SSIS Packages folder, and then click SSIS Import and Export Wizard.
—or—
In SQL Server Data Tools (SSDT), on the Project menu, click SSIS Import and Export Wizard.
—or—
In SQL Server Management Studio, connect to the Database Engine server type, expand Databases, right-click a database, point to Tasks, and then click Import Data or Export data.
—or—
In a command prompt window, run DTSWizard.exe, located in C:\Program Files\Microsoft SQL Server\100\DTS\Binn.

After that it should be pretty much the same (possibly with minor variations in the UI) as in @marc_s's answer.

Yes, Mid.

Dim sub_str
sub_str = Mid(source_str, 10, 5)

The first parameter is the source string, the second is the start index, and the third is the length.

@bobobobo: Note that VBScript strings are 1-based, not 0-based. Passing 0 as an argument to Mid results in "invalid procedure call or argument Mid".

If you are using Relative Layout:

  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/stringname"
    android:layout_centerInParent="true"/>

If you are using LinearLayout

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/stringname"
    android:layout_gravity="center"/>

You should try out json_last_error_msg(). It will give you the error message and tell you what is wrong. It was introduced in PHP 5.5.

$foo = "{"action":"set","user":"123123123123","status":"OK"}";
$data = json_decode($foo, true);
if($data == null) {
    throw new Exception('Decoding JSON failed with the following message: '
                             . json_last_error_msg());
}

// ... JSON decode was good => Let's use the data

What is the truth?

Microsoft's documentation describing the behaviour of their browser is correct.

Is there any solution to hide the addressbar?

No. If you could hide it, then you could use HTML/CSS to make something that looked like a common address bar. You could then put a different address in it. You could then trick people into thinking they were on a different site and entering their password for it.

It is impossible to conceal the user's location from them because it is essential for security that they know what their location is.

I used this simple code:

$("#MyModal .close").click();

Take a look at this: Complete Example

Server:

let exp = require('express');
let app = exp();

//UPDATE: this is seems to be deprecated
//let io = require('socket.io').listen(app.listen(9009));
//New Syntax:
const io = require('socket.io')(app.listen(9009));

app.all('/', function (request, response, next) {
    response.header("Access-Control-Allow-Origin", "*");
    response.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
});

Client:

    var socket = io("127.0.0.1:9009/", {

I remember this from the combination of stackoverflow answers many days ago; but I could not find the main links to mention them

try using the cloning technique.

{
    DataGridViewRow row = (DataGridViewRow)yourdatagrid.Rows[0].Clone();
    // then for each of the values use a loop like below.
    int cc = yourdatagrid.Columns.Count;
    for (int i2 = 0; i < cc; i2++)
    {
        row.Cells[i].Value = yourdatagrid.Rows[0].Cells[i].Value;
    }
    yourdatagrid.Rows.Add(row);
    i++;
    }
}

This should work. I'm not sure about how the binding works though. Hopefully it won't prevent this from working.

From GC Performance Tuning training documents of Oracle:

-Xmn[size]: Size of young generation heap space.

Applications with emphasis on performance tend to use -Xmn to size the young generation, because it combines the use of -XX:MaxNewSize and -XX:NewSize and almost always explicitly sets -XX:PermSize and -XX:MaxPermSize to the same value.

In short, it sets the NewSize and MaxNewSize values of New generation to the same value.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Another example. When building a complex map of maps, the computeIfAbsent() method is a replacement for map's get() method. Through chaining of computeIfAbsent() calls together, missing containers are constructed on-the-fly by provided lambda expressions:

  // Stores regional movie ratings
  Map<String, Map<Integer, Set<String>>> regionalMovieRatings = new TreeMap<>();

  // This will throw NullPointerException!
  regionalMovieRatings.get("New York").get(5).add("Boyhood");

  // This will work
  regionalMovieRatings
    .computeIfAbsent("New York", region -> new TreeMap<>())
    .computeIfAbsent(5, rating -> new TreeSet<>())
    .add("Boyhood");

I wasn't aware of a problem with setAttribute in IE ? However you could directly set the expando property on the node itself:

hiddenInput.id = "uniqueIdentifier";

I had the same issue but I solved it by correcting my form open as shown below :

If this doesn't solve your problem, can you please show how you opened the form ?

Reverse Engineering Approach :

http://www.wikihow.com/Generate-Hibernate-Pojo-Classes-from-DB-Tables

I was having some difficulty translating actual VB.NET to the Expression subset that SSRS uses. You definitely inspired me though and this is what I came up with.

StartDate  
=dateadd("d",0,dateserial(year(dateadd("d",-1,dateserial(year(Today),month(Today),1))),month(dateadd("d",-1,dateserial(year(Today),month(Today),1))),1))

End Date
=dateadd("d",0,dateserial(year(Today),month(Today),1))  

I know it's a bit recursive for the StartDate (first day of last month). Is there anything I'm missing here? These are strictly date fields (i.e. no time), but I think this should capture leap year, etc.

How did I do?

Expanding on Chris' answer. I managed to reverse engineer the token generation process.

The token for the request is based on the text and a global TKK variable set in the page script. These are hashed in JavaScript thus resulting in the tk param.

Somewhere in the page script you will find something like this:

TKK='403413';

This is the amount of hours passed since epoch.

The text is pumped in the following function (somewhat deobfuscated):

I managed to successfully port this to python in my fork of gTTS, so I know this works.

Edit: By now the token generation code used by gTTS has been moved into gTTS-token.

Edit 2: Google has changed the API (somewhere around 2016-05-10), this method requires some modification. I'm currently working on this. In the meantime changing the client to tw-ob seems to work.

Edit 3:

The changes are minor, yet annoying to say the least. The TKK now has two parts. Looking something like 406986.2817744745. As you can see the first part has remained the same. The second part is the sum of two seemingly random numbers. TKK=eval('((function(){var a\x3d2680116022;var b\x3d137628723;return 406986+\x27.\x27+(a+b)})())'); Here \x3d means = and \x27 is '. Both a and b change every UTC minute. At one of the final steps in the algorithm the token is XORed by the second part.

The new token generation code is:

var xr = function(a) {_x000D_
    return function() {_x000D_
        return a_x000D_

If you want to copy from searchContent to content, then code should be as follows

BeanUtils.copyProperties(content, searchContent);

You need to reverse the parameters as above in your code.

From API,

public static void copyProperties(Object dest, Object orig)
                           throws IllegalAccessException,
                                  InvocationTargetException)

Parameters:

dest - Destination bean whose properties are modified

orig - Origin bean whose properties are retrieved

I'm not sure if I understood the question properly.

Anyway, are you looking for this:

std::string ip ="192.168.1.54";
std::stringstream s(ip);
int a,b,c,d; //to store the 4 ints
char ch; //to temporarily store the '.'
s >> a >> ch >> b >> ch >> c >> ch >> d;
std::cout << a << "  " << b << "  " << c << "  "<< d;

Output:

192  168  1  54

Make sure vartabstop is unset

set vartabstop=

Set tabstop to 4

set tabstop=4

When loading the Properties from a Class in the package com.al.common.email.templates you can use

Properties prop = new Properties();
InputStream in = getClass().getResourceAsStream("foo.properties");
prop.load(in);
in.close();

(Add all the necessary exception handling).

If your class is not in that package, you need to aquire the InputStream slightly differently:

InputStream in = 
 getClass().getResourceAsStream("/com/al/common/email/templates/foo.properties");

Relative paths (those without a leading '/') in getResource()/getResourceAsStream() mean that the resource will be searched relative to the directory which represents the package the class is in.

Using java.lang.String.class.getResource("foo.txt") would search for the (inexistent) file /java/lang/String/foo.txt on the classpath.

Using an absolute path (one that starts with '/') means that the current package is ignored.

The difference between .dylib and .so on mac os x is how they are compiled. For .so files you use -shared and for .dylib you use -dynamiclib. Both .so and .dylib are interchangeable as dynamic library files and either have a type as DYLIB or BUNDLE. Heres the readout for different files showing this.

libtriangle.dylib:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00       DYLIB    17       1368   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS



libtriangle.so:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00       DYLIB    17       1256   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS

triangle.so:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64  X86_64        ALL  0x00      BUNDLE    16       1696   NOUNDEFS DYLDLINK TWOLEVEL

The reason the two are equivalent on Mac OS X is for backwards compatibility with other UNIX OS programs that compile to the .so file type.

Compilation notes: whether you compile a .so file or a .dylib file you need to insert the correct path into the dynamic library during the linking step. You do this by adding -install_name and the file path to the linking command. If you dont do this you will run into the problem seen in this post: Mac Dynamic Library Craziness (May be Fortran Only).

IISReset restarts the entire webserver (including all associated sites). If you're just looking to reset a single ASP.NET website, you should just recycle that AppDomain.

The most common way to reset an ASP.NET website is to edit the web.config file, but you can also create an admin page with the following:

public partial class Recycle : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        HttpRuntime.UnloadAppDomain();
    }
}

Here's a blog post I wrote with more info: Avoid IISRESET in ASP.NET Applications

require_relative is a convenient subset of require

require_relative('path')

equals:

require(File.expand_path('path', File.dirname(__FILE__)))

if __FILE__ is defined, or it raises LoadError otherwise.

This implies that:

• require_relative 'a' and require_relative './a' require relative to the current file (__FILE__).

  This is what you want to use when requiring inside your library, since you don't want the result to depend on the current directory of the caller.

• eval('require_relative("a.rb")') raises LoadError because __FILE__ is not defined inside eval.

  This is why you can't use require_relative in RSpec tests, which get evaled.

The following operations are only possible with require:

• require './a.rb' requires relative to the current directory

• require 'a.rb' uses the search path ($LOAD_PATH) to require. It does not find files relative to current directory or path.

  This is not possible with require_relative because the docs say that path search only happens when "the filename does not resolve to an absolute path" (i.e. starts with / or ./ or ../), which is always the case for File.expand_path.

The following operation is possible with both, but you will want to use require as it is shorter and more efficient:

• require '/a.rb' and require_relative '/a.rb' both require the absolute path.

Reading the source

When the docs are not clear, I recommend that you take a look at the sources (toggle source in the docs). In some cases, it helps to understand what is going on.

require:

VALUE rb_f_require(VALUE obj, VALUE fname) {
  return rb_require_safe(fname, rb_safe_level());
}

require_relative:

VALUE rb_f_require_relative(VALUE obj, VALUE fname) {
    VALUE base = rb_current_realfilepath();
    if (NIL_P(base)) {
        rb_loaderror("cannot infer basepath");
    }
    base = rb_file_dirname(base);
    return rb_require_safe(rb_file_absolute_path(fname, base), rb_safe_level());
}

This allows us to conclude that

require_relative('path')

is the same as:

require(File.expand_path('path', File.dirname(__FILE__)))

because:

rb_file_absolute_path   =~ File.expand_path
rb_file_dirname1        =~ File.dirname
rb_current_realfilepath =~ __FILE__

One difference from a debugging perspective:

To debug into Java system classes such as String and ArrayList, you need a special version of the JRE which is compiled with "debug information". The JRE included inside the JDK provides this info, but the regular JRE does not. Regular JRE does not include this info to ensure better performance.

What is debugging information? Here is a quick explanation taken from this blog post:

Modern compilers do a pretty good job converting your high-level code, with its nicely indented and nested control structures and arbitrarily typed variables into a big pile of bits called machine code (or bytecode in case of Java), the sole purpose of which is to run as fast as possible on the target CPU (virtual CPU of your JVM). Java code gets converted into several machine code instructions. Variables are shoved all over the place – into the stack, into registers, or completely optimized away. Structures and objects don’t even exist in the resulting code – they’re merely an abstraction that gets translated to hard-coded offsets into memory buffers.

So how does a debugger know where to stop when you ask it to break at the entry to some function? How does it manage to find what to show you when you ask it for the value of a variable? The answer is – debugging information.

Debugging information is generated by the compiler together with the machine code. It is a representation of the relationship between the executable program and the original source code. This information is encoded into a pre-defined format and stored alongside the machine code. Many such formats were invented over the years for different platforms and executable files.

With the deprecation of GCM and removal of its APIs, it appears that you could see MismatchSenderId if you try to use GCM after May 29, 2019. See the Google GCM and FCM FAQ for more details.

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

Another important difference is that the Hashtable type supports lock-free multiple readers and a single writer at the same time, while Dictionary does not.

In javascript wouldn't you use document.getElementById('item1').innertext?

As of now (Jan 2017 / Angular > 2.0) you can use the following:

changeBackground(): any {
    return { 'background-color': this.color };
}

and

<div class="circle" [ngStyle]="changeBackground()">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

The shortest way is probably like this:

<div class="circle" [ngStyle]="{ 'background-color': color }">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

Modern HTTP is stateful. Old timey HTTP was stateless.

Before Netscape invented cookies and HTTPS in 1994 http could be considered stateless. As time progressed more and more stateful aspects were added for a myriad of reasons, including performance and security.

While HTTP 1 originally sought out to be stateless many HTTP/2 components are the very definition of stateful. HTTP/2 abandoned stateless goals.

No reasonable person can read the HTTP/2 RFC and think it is stateless. The errant "HTTP is stateless" old time dogma is false and far from the current reality of stateful HTTP.

Here's a limited, and not exhaustive list, of stateful HTTP/1 and HTTP/2 components:

• Cookies, named "HTTP State Management Mechanism" by the RFC.
• HTTPS, which stores keys thus state.
• HTTP authentication requires state.
• Web Storage.
• HTTP caching is stateful.
• The very purpose of the stream identifier is state. It's even in the name of the RFC section, "Stream States".
• Header blocks, which establish stream identifiers, are stateful.
• Frames which reference stream identifiers are stateful.
• Header Compression, which the HTTP RFC explicitly says is stateful, is stateful.
• Opportunistic encryption is stateful.

Section 5.1 of the HTTP/2 RFC is a great example of stateful mechanisms defined by the HTTP/2 standard.

Is it safe for web applications to consider HTTP/2 as a stateless protocol?

HTTP/2 is a stateful protocol, but that doesn't mean your HTTP/2 application can't be stateless. You can choose to not use certain stateful features for stateless HTTP/2 applications by using only a subset of HTTP/2 features.

Cookies and some other stateful mechanisms, or less obvious stateful mechanisms, are later HTTP additions. HTTP 1 is said to be stateless although in practice we use standardized stateful mechanisms, like cookies, TLS, and caching. Unlike HTTP/1, HTTP/2 defines stateful components in its standard from the very beginning. A particular HTTP/2 application can use a subset of HTTP/2 features to maintain statelessness, but the protocol itself anticipate state to be the norm, not the exception.

Existing applications, even HTTP 1 applications, needing state will break if trying to use them statelessly. It can be impossible to log into some HTTP/1.1 websites if cookies are disabled, thus breaking the application. It may not be safe to assume that a particular HTTP 1 application does not use state. This is no different for HTTP/2.

Say it with me one last time:

HTTP/2 is a stateful protocol.

If you have some tiles that exceed the bounds of your diamond, I recommend drawing in depth order:

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

Actually, Docker images are stored in two files as shown by following command

$ docker info

Data file: /var/lib/docker/devicemapper/devicemapper/data

Metadata file: /var/lib/docker/devicemapper/devicemapper/metadata

Generate the range of data first and then shuffle it like this

import random
data = range(numLow, numHigh)
random.shuffle(data)
print data

By doing this way, you will get all the numbers in the particular range but in a random order.

But you can use random.sample to get the number of elements you need, from a range of numbers like this

print random.sample(range(numLow, numHigh), 3)

You can use a combination of @JsonSetter, and @JsonGetter to control the deserialization, and serialization of your property, respectively. This will also allow you to keep standardized getter and setter method names that correspond to your actual field name.

import com.fasterxml.jackson.annotation.JsonSetter;    
import com.fasterxml.jackson.annotation.JsonGetter;

class Coordinates {
    private int red;

    //# Used during serialization
    @JsonGetter("r")
    public int getRed() {
        return red;
    }

    //# Used during deserialization
    @JsonSetter("red")
    public void setRed(int red) {
        this.red = red;
    }
}

With my pymongo version: 3.2.2 I had do the following

Here you can find info on how to upgrade to v3: http://tosbourn.com/2013/08/javascript/upgrading-from-bootstraps-typeahead-to-typeahead-js/

Here are some examples too: http://twitter.github.io/typeahead.js/examples/

If you want to ignore the insertion of existing value, there must be a Key field in your Table. Just create a table With Primary Key Field Like:

CREATE TABLE IF NOT EXISTS TblUsers (UserId INTEGER PRIMARY KEY, UserName varchar(100), ContactName varchar(100),Password varchar(100));

And Then Insert Or Replace / Insert Or Ignore Query on the Table Like:

INSERT OR REPLACE INTO TblUsers (UserId, UserName, ContactName ,Password) VALUES('1','UserName','ContactName','Password');

It Will Not Let it Re-Enter The Existing Primary key Value... This Is how you can Check Whether a Value exists in the table or not.

If each user has its own SQL Server login you could try this

select 
    so.name, su.name, so.crdate 
from 
    sysobjects so 
join 
    sysusers su on so.uid = su.uid  
order by 
    so.crdate

I think your problems are due to your test structure. I've found it difficult to mix mocking with the traditional method of implementing interfaces in the test class (as you've done here).

If you implement the listener as a Mock you can then verify the interaction.

Listener listener = mock(Listener.class);
w.addListener(listener);
world.doAction(..);
verify(listener).doAction();

This should satisfy you that the 'World' is doing the right thing.

You may use apache commons StringUtils

StringUtils.leftPad("129018", 10, "0");

Actually, in this case it's quite simple: apply the vertical align to the image. Since it's all in one line, it's really the image you want aligned, not the text.

<!-- moved "vertical-align:middle" style from span to img -->_x000D_
<div>_x000D_
  <img style="vertical-align:middle" src="https://placehold.it/60x60">_x000D_
  <span style="">Works.</span>_x000D_
</div>

Tested in FF3.

Now you can use flexbox for this type of layout.

.box {_x000D_
   display: flex;_x000D_
   align-items:center;_x000D_
}

<div class="box">_x000D_
    <img src="https://placehold.it/60x60">_x000D_
    <span style="">Works.</span>_x000D_
</div>

The answers here helped me up to a point, but I had a problem on HTML5 Number input fields when clicking the up/down buttons in Chrome.

If you click one of the buttons, and left the mouse over the button the number would keep changing as if you were holding the mouse button because the mouseup was being thrown away.

I solved this by removing the mouseup handler as soon as it had been triggered as below:

    $("input:number").focus(function () {
        var $elem = $(this);
        $elem.select().mouseup(function (e) {
            e.preventDefault();
            $elem.unbind(e.type);
        });
    });

Hope this helps people in the future...

It seems I misread the question, but for reference, you can extract a range of the DOM (not to the clipboard; compatible with all modern browsers), and combine it with the oncopy, onpaste, and onbeforepaste events to get the clipboard behaviour. Here's the code to achieve this:

function clipBoard(sCommand) {
  var oRange = contentDocument.createRange();
  oRange.setStart(startNode, startOffset);
  oRange.setEnd(endNode, endOffset);

  /* This is where the actual selection happens.
     in the above, startNode and endNode are
     DOM nodes defining the beginning and
     end of the "selection" respectively.

     startOffset and endOffset are constants
     that are defined as follows:

         END_TO_END: 2
         END_TO_START: 3
         NODE_AFTER: 1
         NODE_BEFORE: 0
         NODE_BEFORE_AND_AFTER: 2
         NODE_INSIDE: 3
         START_TO_END: 1
         START_TO_START: 0

     And it would be used like oRange.START_TO_END
  */

  switch(sCommand) {

    case "cut":
      this.oFragment = oRange.extractContents();
      oRange.collapse();
      break;

    case "copy":
      this.oFragment = oRange.cloneContents();
      break;

    case "paste":
      oRange.deleteContents();
      var cloneFragment = this.oFragment.cloneNode(true)
      oRange.insertNode(cloneFragment);
      oRange.collapse();
      break;
  }
}

Always best to have a primary key. This way it meets first normal form and allows you to continue along the database normalization path.

As stated by others, there are some reasons not to have a primary key, but most will not be harmed if there is a primary key

*first html page*

<form action="display.jsp" >
    <input type="text" name="serialNumber" />
    <input type="submit" value="Submit" />
</form>


*Second html page*
<body>
<p>The serial number is:<%=request.getParameter("serialNumber") %></p>
</body>


you will get the value of the textbox on another page.

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

ids and classes are still attributes, so you can apply a regexp attribute filter to them if you select accordingly. Read more here: http://rosshawkins.net/archive/2011/10/14/jquery-wildcard-selectors-some-simple-examples.aspx

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

    $data = array(
            'name' => $name ,
            'email' => $email,
            'time' =>date('Y-m-d H:i:s')
            );
            $this->db->insert('mytable', $data);

I believe - your Laravel files/folders should not be placed in root directory.

e.g. If your domain is pointed to public_html directory then all content should placed in that directory. How ? let me tell you

1. Copy all files and folders ( including public folder ) in public html
2. Copy all content of public folder and paste it in document root ( i.e. public_html )
3. Remove the public folder

4. Open your bootstrap/paths.php and then changed 'public' => __DIR__.'/../public', into 'public' => __DIR__.'/..',

5. and finally in index.php,

   Change

require __DIR__.'/../bootstrap/autoload.php';

$app = require_once __DIR__.'/../bootstrap/start.php';

into

require __DIR__.'/bootstrap/autoload.php';

$app = require_once __DIR__.'/bootstrap/start.php';

Your Laravel application should work now.

It's hard to do this.

There is a min-height: css style, but it doesn't work in all browsers. You can use it, but the biggest problem is that you will need to set it to something like 90% or numbers like that (percents), but the top and bottom divs use fixed pixel sizes, and you won't be able to reconcile them.

 var minHeight = $(window).height() -
                 $('#a').outerHeight(true) -
                 $('#c').outerHeight(true));

if($('#b').height() < minHeight) $('#b').height(minHeight);

I know a and c have fixed heights, but I rather measure them in case they change later.

Also, I am measuring the height of b (I don't want to make is smaller after all), but if there is an image in there that did not load the height can change, so watch out for things like that.

It may be safer to do:

$('#b').prepend('<div style="float: left; width: 1px; height: ' + minHeight + 'px;">&nbsp;</div>');

Which simply adds an element into that div with the correct height - that effectively acts as min-height even for browsers that don't have it. (You may want to add the element into your markup, and then just control the height of it via javascript instead of also adding it that way, that way you can take it into account when designing the layout.)

Getting all the occurrences and the position of one or more (identical) items in a list

With enumerate(alist) you can store the first element (n) that is the index of the list when the element x is equal to what you look for.

>>> alist = ['foo', 'spam', 'egg', 'foo']
>>> foo_indexes = [n for n,x in enumerate(alist) if x=='foo']
>>> foo_indexes
[0, 3]
>>>

Let's make our function findindex

This function takes the item and the list as arguments and return the position of the item in the list, like we saw before.

def indexlist(item2find, list_or_string):
  "Returns all indexes of an item in a list or a string"
  return [n for n,item in enumerate(list_or_string) if item==item2find]

print(indexlist("1", "010101010"))

Output

[1, 3, 5, 7]

Simple

for n, i in enumerate([1, 2, 3, 4, 1]):
    if i == 1:
        print(n)

Output:

0
4

The solution I end up using most is based off of Tomas Petricek's answer. I usually want to do something with both the attribute and property.

var props = from p in this.GetType().GetProperties()
            let attr = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attr.Length == 1
            select new { Property = p, Attribute = attr.First() as MyAttribute};

I had similar problem against 2 different databases (DB2 and SQL), finally I solved it by using CAST in the source query from DB2. I also take advantage of using a query by adapting the source column to varchar and avoiding the useless blank spaces:

CAST(RTRIM(LTRIM(COLUMN_NAME)) AS VARCHAR(60) CCSID UNICODE 
   FOR SBCS DATA)  COLUMN_NAME

The important issue here is the CCSID conversion.

To get AM/PM, Check if the hour portion is less than 12, then it is AM, else PM.

To get the hour, do (hour % 12) || 12.

This should do it:

var timeString = "18:00:00";
var H = +timeString.substr(0, 2);
var h = H % 12 || 12;
var ampm = (H < 12 || H === 24) ? "AM" : "PM";
timeString = h + timeString.substr(2, 3) + ampm;

http://jsfiddle.net/Skwt7/4/

That assumes that AM times are formatted as, eg, 08:00:00. If they are formatted without the leading zero, you would have to test the position of the first colon:

var hourEnd = timeString.indexOf(":");
var H = +timeString.substr(0, hourEnd);
var h = H % 12 || 12;
var ampm = (H < 12 || H === 24) ? "AM" : "PM";
timeString = h + timeString.substr(hourEnd, 3) + ampm;

First you must stop the mousewheel event by either:

1. Disabling it with mousewheel.disableScroll
2. Intercepting it with e.preventDefault();
3. By removing focus from the element el.blur();

The first two approaches both stop the window from scrolling and the last removes focus from the element; both of which are undesirable outcomes.

One workaround is to use el.blur() and refocus the element after a delay:

$('input[type=number]').on('mousewheel', function(){
  var el = $(this);
  el.blur();
  setTimeout(function(){
    el.focus();
  }, 10);
});

before you write set(XXXXX) you have used "set" as a variable e.g.

set = 90 #you have used "set" as an object
…
…
a = set(["Blah", "Hello"])
a = list(a)

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

youtube.com/v/{vidid}
youtube.com/vi/{vidid}
youtube.com/?v={vidid}
youtube.com/?vi={vidid}
youtube.com/watch?v={vidid}
youtube.com/watch?vi={vidid}
youtu.be/{vidid}

I improved it slightly to support: http://www.youtube.com/v/5xADESocujo?feature=autoshare&version=3&autohide=1&autoplay=1

The line I use now is:

preg_match("#(?<=v=)[a-zA-Z0-9-]+(?=&)|(?<=v\/)[^&\n]+(?=\?)|(?<=v=)[^&\n]+|(?<=youtu.be/)[^&\n]+#", $link, $matches);

If you just want the date:

SELECT MIN(date) as EarliestDate
FROM YourTable
WHERE id = 2

If you want all of the information:

SELECT TOP 1 id, name, score, date
FROM YourTable
WHERE id = 2
ORDER BY Date

Prevent loops when you can. Loops often lead to cursors, and cursors are almost never necessary and very often really inefficient.

All settings listed here are correct, but here are the most optimal and sufficient solution:

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
character-set-server = utf8
collation-server = utf8_unicode_ci

[client]
default-character-set = utf8

Add these to /etc/mysql/my.cnf.

Please note, I choose utf8_unicode_ci type of collation due to the performance issue.

The result is:

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database   | utf8_unicode_ci |
| collation_server     | utf8_unicode_ci |
+----------------------+-----------------+

And this is when you connect as non-SUPER user!

For example, the difference between connection as SUPER and non-SUPER user (of course in case of utf8_unicode_ci collation):

user with SUPER priv.:

mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_general_ci | <---
| collation_database   | utf8_unicode_ci |
| collation_server     | utf8_unicode_ci |
+----------------------+-----------------+

user with non-SUPER priv.:

mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+
| Variable_name        | Value           |
+----------------------+-----------------+
| collation_connection | utf8_unicode_ci |
| collation_database   | utf8_unicode_ci |
| collation_server     | utf8_unicode_ci |
+----------------------+-----------------+

I wrote a comprehensive article (rus) explaining in details why you should use one or the other option. All types of Character Sets and Collations are considered: for server, for database, for connection, for table and even for column.

I hope this and the article will help to clarify unclear moments.

We do it this way...

String.prototype.getValueByKey = function (k) {
    var p = new RegExp('\\b' + k + '\\b', 'gi');
    return this.search(p) != -1 ? decodeURIComponent(this.substr(this.search(p) + k.length + 1).substr(0, this.substr(this.search(p) + k.length + 1).search(/(&|;|$)/))) : "";
};

How about:

ACell.ListObject.DataBodyRange.Rows.Delete

That will keep your table structure and headings, but clear all the data and rows.

EDIT: I'm going to just modify a section of my answer from your previous post, as it does mostly what you want. This leaves just one row:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
   .DataBodyRange.Rows(1).Specialcells(xlCellTypeConstants).ClearContents
End With

If you want to leave all the rows intact with their formulas and whatnot, just do:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Specialcells(xlCellTypeConstants).ClearContents
End With

Which is close to what @Readify suggested, except it won't clear formulas.

I have found a recent article which I found both short and very good. It covers .NET Standard, .NET Core and .NET Framework and their relationship. I highly recommend it. Unfortunately, I have no time to adapt and put it here.

Original answer content below:

So, based on the latest official entry on the subject, here are some key points as I see them:

.NET Core is essentially a fork of the .NET Framework whose implementation is also optimized around factoring concerns.

We think of .NET Core as not being specific to either .NET Native nor ASP.NET 5 – the BCL and the runtimes are general purpose and designed to be modular. As such, it forms the foundation for all future .NET verticals.

So .NET Native and ASP.NET 5 are just a test "subjects" for new framework configuration, partially this maybe because they are quite different:

See, they even need separate low-level, but a major part of BCL is still common:

We think of .NET Core as not being specific to either .NET Native nor ASP.NET 5 – the BCL and the runtimes are general purpose and designed to be modular. As such, it forms the foundation for all future .NET verticals.

I.e., magenta rectangles on top will be added massively with new App Models, but the base will remain common.

NuGet deployment:

In contrast to the .NET Framework, the .NET Core platform will be delivered as a set of NuGet packages. We’ve settled on NuGet because that’s where the majority of the library ecosystem already is.

Relationship with current frameworks:

For Visual Studio 2015 our goal is to make sure that .NET Core is a pure subset of the .NET Framework. In other words, there wouldn’t be any feature gaps. After Visual Studio 2015 is released our expectation is that .NET Core will version faster than the .NET Framework. This means that there will be points in time where a feature will only be available on the .NET Core based platforms.

Summary:

The .NET Core platform is a new .NET stack that is optimized for open source development and agile delivery on NuGet. We’re working with the Mono community to make it great on Windows, Linux and Mac, and Microsoft will support it on all three platforms.

We’re retaining the values that the .NET Framework brings to enterprise class development. We’ll offer .NET Core distributions that represent a set of NuGet packages that we tested and support together. Visual Studio remains your one- stop-shop for development. Consuming NuGet packages that are part of a distribution doesn’t require an Internet connection.

Basically this can be thought as a .NET 4.6 with a changed distribution model, which, simultaneously, is being in a process of becoming open source.

In IPython (jupyter) 7.3 and later, there is a magic %pip and %conda command that will install into the current kernel (rather than into the instance of Python that launched the notebook).

%pip install geocoder

In earlier versions, you need to use sys to fix the problem like in the answer by FlyingZebra1

import sys
!{sys.executable} -m pip install geocoder

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

If you need to retrieve more columns other than columns which are in group by then you can consider below query. Check it once whether it is performing well or not.

SELECT 
a.[CUSTOMER ID], 
a.[NAME], 
(select SUM(b.[AMOUNT]) from INV_DATA b
where b.[CUSTOMER ID] = a.[CUSTOMER ID]
GROUP BY b.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA a

onchange will work only if the value of the textbox changed compared to the value it had before, so for the first time it won't work because the state didn't change.

So it is better to use onblur event or on submitting the form.

function checkTextField(field) {_x000D_
  document.getElementById("error").innerText =_x000D_
    (field.value === "") ? "Field is empty." : "Field is filled.";_x000D_
}

<input type="text" onblur="checkTextField(this);" />_x000D_
<p id="error"></p>

(Or old live demo.)

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

If letters are always in the beginning or at the end, you can simply just use trim...no regex needed

$string = trim($string, "a..zA..Z"); // this also take care of lowercase

"AR3,373.31" --> "3,373.31"
"12.322,11T" --> "12.322,11"
"12.322,11"  --> "12.322,11"

Missed property runat="server" or in code use Request.Params["TextArea1"]

Read more about Array and ArrayList

List<String> aList = new ArrayList<String>();
aList.add("apple");   
aList.add("banana");   
aList.add("orange");   
String result = alist.get(1);  //this will retrieve banana

Note: Index starts from 0 i.e. Zero

• Resource

Say you have static fields and methods inside a class called MyClass inside a package called myPackage and you want to access them directly by typing myStaticField or myStaticMethod without typing each time MyClass.myStaticField or MyClass.myStaticMethod.

Note : you need to do an import myPackage.MyClass or myPackage.* for accessing the other resources

To subtract hours, you need to use the HOUR_OF_DAY constant. Within that, include the number with the negative sign. This would be the hours you want to reduce. All this is done under the Calendar add() method.

The following is an example:

import java.util.Calendar;
public class Example {
  public static void main(String[] args) {
   Calendar c = Calendar.getInstance();
     System.out.println("Date : " + c.getTime());
       // 2 hours subtracted
   c.add(Calendar.HOUR_OF_DAY, -2);
   System.out.println("After subtracting 2 hrs : " + c.getTime());
 }
}

Here is the output:

Date : Sun Dec 16 16:28:53 UTC 2018
After subtracting 2 hrs : Sun Dec 16 14:28:53 UTC 2018

Here are more code examples that will produce the argument null exception:

List<Myobj> myList = null;
//from this point on, any linq statement you perform on myList will throw an argument null exception
myList.ToList();
myList.GroupBy(m => m.Id);
myList.Count();
myList.Where(m => m.Id == 0);
myList.Select(m => m.Id == 0);
//etc...

 $('input[type="radio"]').change(function(){
      if($("input[name='group']:checked")){
      $(div).show();
    }
  });

Remember that technically javascript objects don't have methods. They have properties, some of which may be function objects. That means that you can enumerate the methods in an object just like you can enumerate the properties. This (or something close to this) should work:

var bar
for (bar in foo)
{
    console.log("Foo has property " + bar);
}

There are complications to this because some properties of objects aren't enumerable so you won't be able to find every function on the object.

Well there is a very easy way, but just setting android:animateLayoutChanges="true" will not work. You need to enableTransitionType in you activity. Check this link for more info: http://www.thecodecity.com/2018/03/android-animation-on-view-visibility.html

For those who are using "High Contrast" windows themes but still want a regular Visual Studio theme you might notice that the theme selector drop down is disabled. You can still change it by doing the following...

1. Going to the registry key: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\Themes (or whichever version of VS you are using)
2. Export the key of the theme you want (it's a bunch of random letters / numbers) to a .reg file.
3. Then copy the "high contrast" key's name (again random letters / numbers)
4. Delete the high contrast key and then rename the dark theme to the copied name
5. Then import the exported theme from the reg file.

This permanently sets the theme to the one you've chosen.

This method removes not only child (and other descendant) elements, but also any text within the set of matched elements. This is because, according to the DOM specification, any string of text within an element is considered a child node of that element.

$('textarea').empty()

This creates a "See Also" heading containing the link, i.e.:

/**
 * @see <a href="http://google.com">http://google.com</a>
 */

will render as:

See Also:
           http://google.com

whereas this:

/**
 * See <a href="http://google.com">http://google.com</a>
 */

will create an in-line link:

See http://google.com

Wait -- did you actually mean that "the same number of rows ... are being processed" or that "the same number of rows are being returned"? In general, the outer join would process many more rows, including those for which there is no match, even if it returns the same number of records.

Easiest way I think is:

var s = yourString.replace(/.*_/g,"_");

It works only if the frame contains page from the same domain (does not violate same-origin policy)

See this:

var iframe = $('#your_iframe').contents();

iframe.find('your_clicable_item').click(function(event){
   console.log('work fine');
});

Just try the code below:

As I see you have inserted 'r+' or this command open the file in read mode so you are not able to write into it, so you have to open file in write mode 'w' if you want to overwrite the file contents and write new data, otherwise you can append data to file by using 'a'

I hope this will help ;)

f = open('testfile.txt', 'w')# just put 'w' if you want to write to the file 

x = f.readlines() #this command will read file lines

y = int(x)+1

print y
z = str(y) #making data as string to avoid buffer error
f.write(z)

f.close()

Caution, member enumeration only works if the collection itself has no member of the same name. So if you had an array of FileInfo objects, you couldn't get an array of file lengths by using

 $files.length # evaluates to array length

And before you say "well obviously", consider this. If you had an array of objects with a capacity property then

 $objarr.capacity

would work fine UNLESS $objarr were actually not an [Array] but, for example, an [ArrayList]. So before using member enumeration you might have to look inside the black box containing your collection.

(Note to moderators: this should be a comment on rageandqq's answer but I don't yet have enough reputation.)

When you declare a variable, you need to declare its type - in this case: int. Also you've put a random comma in the while loop. It probably worth looking up the syntax for Java and consider using a IDE that picks up on these kind of mistakes. You probably want something like this:

int [] numbers = { 1, 2, 3, 4, 5 ,6, 7, 8, 9 , 10 };
int sum = 0;
for(int i = 0; i < numbers.length; i++){
    sum += numbers[i];
}
System.out.println("The sum is: " + sum);

The cookies file format apparently consists of a line per cookie and each line consists of the following seven tab-delimited fields:

• domain - The domain that created AND that can read the variable.
• flag - A TRUE/FALSE value indicating if all machines within a given domain can access the variable. This value is set automatically by the browser, depending on the value you set for domain.
• path - The path within the domain that the variable is valid for.
• secure - A TRUE/FALSE value indicating if a secure connection with the domain is needed to access the variable.
• expiration - The UNIX time that the variable will expire on. UNIX time is defined as the number of seconds since Jan 1, 1970 00:00:00 GMT.
• name - The name of the variable.
• value - The value of the variable.

From http://www.cookiecentral.com/faq/#3.5

This will only ever hit document.cookie ONE time. Every subsequent request will be instant.

(function(){
    var cookies;

    function readCookie(name,c,C,i){
        if(cookies){ return cookies[name]; }

        c = document.cookie.split('; ');
        cookies = {};

        for(i=c.length-1; i>=0; i--){
           C = c[i].split('=');
           cookies[C[0]] = C[1];
        }

        return cookies[name];
    }

    window.readCookie = readCookie; // or expose it however you want
})();

I'm afraid there really isn't a faster way than this general logic unless you're free to use .forEach which is browser dependent (even then you're not saving that much)

Your own example slightly compressed to 120 bytes:

function read_cookie(k,r){return(r=RegExp('(^|; )'+encodeURIComponent(k)+'=([^;]*)').exec(document.cookie))?r[2]:null;}

You can get it to 110 bytes if you make it a 1-letter function name, 90 bytes if you drop the encodeURIComponent.

I've gotten it down to 73 bytes, but to be fair it's 82 bytes when named readCookie and 102 bytes when then adding encodeURIComponent:

function C(k){return(document.cookie.match('(^|; )'+k+'=([^;]*)')||0)[2]}

Things have moved on a bit since this thread started.

Now, you could use

string.Concat(s.TakeWhile((c) => c != '-'));

If you don't want to SELECT SLEEP(1);, you can also DO SLEEP(1); It's useful for those situations in procedures where you don't want to see output.

e.g.

SELECT ...
DO SLEEP(5);
SELECT ...

They have nothing to do with each other.

Java is statically typed, compiles, runs on its own VM.

Javascript is dynamically typed, interpreted, and runs in a browser. It also has first-class functions and anonymous functions, which Java does not. It has direct access to web-page elements, which makes it useful for doing client-side processing.

They are also somewhat similar in syntax, but that's about it.

require 'json'

hash = JSON.parse string

work with the hash and do what you want to do.

After trying out all the suggested solutions, I couldn't find any very helpful.

I finally tried the following:

[self.tabBar setTintColor:[UIColor orangeColor]];

which worked out perfectly.

I only provided one image for every TabBarItem. Didn't even need a selectedImage.

I even used it inside the Child-ViewControllers to set different TintColors:

UIColor *theColorYouWish = ...;
if ([[self.parentViewController class] isSubclassOfClass:[UITabBarController class]]){
    UITabBarController *tbc = (UITabBarController *) self.parentViewController;
    [tbc.tabBar setTintColor:theColorYouWish];
}

Short and sweet, uncomment this line in wamp/bin/php/php5.3.13(or whatever php version):
;extension=php_openssl.dll (remove the ;)
Now run the command line installation of Composer. You won't have an error.
Good to go!

If you dig into NSInteger's implementation:

#if __LP64__
typedef long NSInteger;
#else
typedef int NSInteger;
#endif

Simply, the NSInteger typedef does a step for you: if the architecture is 32-bit, it uses int, if it is 64-bit, it uses long. Using NSInteger, you don't need to worry about the architecture that the program is running on.

In addition, for those looking to replace more than one character in a column, you can do it using regular expressions:

import re
chars_to_remove = ['.', '-', '(', ')', '']
regular_expression = '[' + re.escape (''. join (chars_to_remove)) + ']'

df['string_col'].str.replace(regular_expression, '', regex=True)

float(item) do the right thing: it converts its argument to float and and return it, but it doesn't change argument in-place. A simple fix for your code is:

new_list = []
for item in list:
    new_list.append(float(item))

The same code can written shorter using list comprehension: new_list = [float(i) for i in list]

To change list in-place:

for index, item in enumerate(list):
    list[index] = float(item)

BTW, avoid using list for your variables, since it masquerades built-in function with the same name.

it might be too late but there is neat solution based on Task.WaitAny (c# 5 +) :

 public static bool ConnectWithTimeout(this Socket socket, string host, int port, int timeout)
        {
            bool connected = false;
            Task result = socket.ConnectAsync(host, port);               
            int index = Task.WaitAny(new[] { result }, timeout);
            connected = socket.Connected;
            if (!connected) {
              socket.Close();
            }

            return connected;
        }

@Paul Cavacas, I had the same issue and I solved by setting the Input() decorator above the getter.

  @Input('allowDays')
  get in(): any {
    return this._allowDays;
  }

  //@Input('allowDays')
  // not working
  set in(val) {
    console.log('allowDays = '+val);
    this._allowDays = val;
  }

If you are setting up the ANDROID_HOME environment on MacOS Catalina , .bash_profile is no longer apple's default shell and it won't persist your path variables. Use .zprofile instead and follow the environment setup instructions in react-native documentation or others. .bash_profile will keep creating new file which won't make the path permanent or persist on closing the terminal on your system path.

I tried function toFixed(2) many times. Every time console shows "toFixed() is not a function".

but how I resolved is By using Math.round()

eg:

if ($(this).attr('name') == 'time') {
    var value = parseFloat($(this).val());
    value = Math.round(value*100)/100; // 10 defines 1 decimals, 100 for 2, 1000 for 3
    alert(value);
}

this thing surely works for me and it might help you guys too...

If you ultimately want to convert the double output of your round() function to an int, then the accepted solutions of this question will look something like:

int roundint(double r) {
  return (int)((r > 0.0) ? floor(r + 0.5) : ceil(r - 0.5));
}

This clocks in at around 8.88 ns on my machine when passed in uniformly random values.

The below is functionally equivalent, as far as I can tell, but clocks in at 2.48 ns on my machine, for a significant performance advantage:

int roundint (double r) {
  int tmp = static_cast<int> (r);
  tmp += (r-tmp>=.5) - (r-tmp<=-.5);
  return tmp;
}

Among the reasons for the better performance is the skipped branching.

Create a new AVD with the AVD Manager and set the Target to API Level 7. Try running your application with that AVD. Additionally, make sure that your min sdk in your Manifest file is at least set to 7.

Check local_listener definition in your spfile or pfile. In my case, the problem was with pfile, I had moved the pfile from a similar environment and it had LISTENER_sid as LISTENER and not just LISTENER.

To resolve this, If you're using Windows OS

1. Open your php.ini. Search and uncomment this line - extension=php_mysql.dll

   (Please also check If the PHP directive points to where your extensions is located.
   Mine is extension_dir = "C:\php-5.4.8-Win32-VC9-x86\ext")

2. Restart Apache and refresh your page

Yes, that is one way to get the first line of output from a command.

If the command outputs anything to standard error that you would like to capture in the same manner, you need to redirect the standard error of the command to the standard output stream:

utility 2>&1 | head -n 1

There are many other ways to capture the first line too, including sed 1q (quit after first line), sed -n 1p (only print first line, but read everything), awk 'FNR == 1' (only print first line, but again, read everything) etc.

You can't directly do array2 = array1, because in this case you manipulate the addresses of the arrays (char *) and not of their inner values (char).

What you, conceptually, want is to do is iterate through all the chars of your source (array1) and copy them to the destination (array2). There are several ways to do this. For example you could write a simple for loop, or use memcpy.

That being said, the recommended way for strings is to use strncpy. It prevents common errors resulting in, for example, buffer overflows (which is especially dangerous if array1 is filled from user input: keyboard, network, etc). Like so:

// Will copy 18 characters from array1 to array2
strncpy(array2, array1, 18);

As @Prof. Falken mentioned in a comment, strncpy can be evil. Make sure your target buffer is big enough to contain the source buffer (including the \0 at the end of the string).

If you don't want to put @SuppressWarning("unchecked") on each sf.getEntries() call, you can always make a wrapper that will return List.

See this other question

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

My solution is a bit different:

$( 'input[name="your_radio_input_name"]:radio:first' ).click();

here the link to webreports version 12 https://www.nuget.org/packages/Microsoft.ReportViewer.WebForms.v12/12.0.0?_src=template

after the package installed

on your toolbox browse the dll reference it to bin then that's it run the visual studio

You need to have access as well on the site that you will be iframing. i found the best solution here: https://gist.github.com/MateuszFlisikowski/91ff99551dcd90971377

yourotherdomain.html

<script type='text/javascript' src="js/jquery.min.js"></script>
<script type='text/javascript'>
  // Size the parent iFrame
  function iframeResize() {
    var height = $('body').outerHeight(); // IMPORTANT: If body's height is set to 100% with CSS this will not work.
    parent.postMessage("resize::"+height,"*");
  }

  $(document).ready(function() {
    // Resize iframe
    setInterval(iframeResize, 1000);
  });
</script>

your website with iframe

<iframe src='example.html' id='edh-iframe'></iframe>
<script type='text/javascript'>
  // Listen for messages sent from the iFrame
  var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
  var eventer = window[eventMethod];
  var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

  eventer(messageEvent,function(e) {
    // If the message is a resize frame request
    if (e.data.indexOf('resize::') != -1) {
      var height = e.data.replace('resize::', '');
      document.getElementById('edh-iframe').style.height = height+'px';
    }
  } ,false);
</script>

I can highly recommend Squirrel SQL.

For the sake of completeness, there is also a data.table solution:

library(data.table)
result <- setDT(df)[, paste0(names(df), "_length") := lapply(.SD, stringr::str_length)]
result
#      col1     col2 col1_length col2_length
#1:     abc adf qqwe           3           8
#2:    abcd        d           4           1
#3:       a        e           1           1
#4: abcdefg        f           7           1

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

-n is "not to overwrite" but his question is totally opposite what you replied for.

To avoid this confirmation you can simply run the cp command wiht absolute path, it will avoid the alias.

/bin/cp sourcefile destination

Also check if your xampp is installed in the main directory like C or D or E and not in or within a folder of that directory? i.e. ( "D:/Xampp" or is it "D:/something/Xampp") if its not in the main path of the directory, it will show this error.

copy your xampp directory from "D:\Something\Xampp" to "D:"
So it becomes like this "D:\Xampp" and the issue will be resolved.

Did you try list(x)??

 y = '+123-456-7890'
 c =list(y)
 c

['+', '1', '2', '3', '-', '4', '5', '6', '-', '7', '8', '9', '0']

Basically, you're not allowed to request JSON data from another domain via AJAX due to same-origin policy. AJAX allows you to fetch data after a page has already loaded, and then execute some code/call a function once it returns. We can't use AJAX but we are allowed to inject <script> tags into our own page and those are allowed to reference scripts hosted at other domains.

Usually you would use this to include libraries from a CDN such as jQuery. However, we can abuse this and use it to fetch data instead! JSON is already valid JavaScript (for the most part), but we can't just return JSON in our script file, because we have no way of knowing when the script/data has finished loading and we have no way of accessing it unless it's assigned to a variable or passed to a function. So what we do instead is tell the web service to call a function on our behalf when it's ready.

For example, we might request some data from a stock exchange API, and along with our usual API parameters, we give it a callback, like ?callback=callThisWhenReady. The web service then wraps the data with our function and returns it like this: callThisWhenReady({...data...}). Now as soon as the script loads, your browser will try to execute it (as normal), which in turns calls our arbitrary function and feeds us the data we wanted.

It works much like a normal AJAX request except instead of calling an anonymous function, we have to use named functions.

jQuery actually supports this seamlessly for you by creating a uniquely named function for you and passing that off, which will then in turn run the code you wanted.

On Fedora 32, I managed to solve this same issue by installing lipq5-devel specifically.

If you install postgresql from the official repository, you will have several versions that won't fix the problem, so it's really a matter of trying out which one it needs.

I'm not 100% sure, but I believe the error was caused by some client-side JavaScript that was turning exports into an object. Some code in the Slick plugin (see below) calls the require function if exports is not undefined.

Here's the portion of code I had to change in slick.js. You can see I am just commenting out the if statements, and, instead, I'm just calling factory(jQuery).

;(function(factory) {
console.log('slick in factory', define, 'exports', exports, 'factory', factory);
'use strict';
// if (typeof define === 'function' && define.amd) {
//     define(['jquery'], factory);
// } else if (typeof exports !== 'undefined') {
//     module.exports = factory(require('jquery'));
// } else {
//     factory(jQuery);
// }
factory(jQuery);
}

This is a bit less code and can be done in a single line.

string packUri = "pack://application:,,,/AssemblyName;component/Images/icon.png";
_image.Source = new ImageSourceConverter().ConvertFromString(packUri) as ImageSource;

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

Simply add below param to your spark-submit command

--conf "spark.driver.extraJavaOptions=-Dlog4jspark.root.logger=WARN,console"

This overrides system value temporarily only for that job. Check exact property name (log4jspark.root.logger here) from log4j.properties file.

Hope this helps, cheers!

Had the same errors, my story was following: after bad merging (via git) one of my .csproj files had duplicated compile entries like:

<Compile Include="Clients\Tree.cs" />
<Compile Include="Clients\Car.cs" />
<Compile Include="Clients\Tree.cs" />        //it's a duplicate

If you have a big solution and more than 300 messages in the errors window it's hard to detect this issue. So I've opened damaged .csproj file via notepad and removed duplicated entries. Worked in my case.

In order to see images, plots and anything displayed on windows on your remote machine you need to connect to it like this:

ssh -X user@hostname

That way you enable the access to the X server. The X server is a program in the X Window System that runs on local machines (i.e., the computers used directly by users) and handles all access to the graphics cards, display screens and input devices (typically a keyboard and mouse) on those computers.

More info here.

First of all you need to understand that final output of both the statements will be same i.e. to remove all the spaces from given string.

However x.replaceAll("\\s+", ""); will be more efficient way of trimming spaces (if string can have multiple contiguous spaces) because of potentially less no of replacements due the to fact that regex \\s+ matches 1 or more spaces at once and replaces them with empty string.

So even though you get the same output from both it is better to use:

x.replaceAll("\\s+", "");

I was having the same issue and fixed it by changing the default program to open .ps1 files to PowerShell. It was set to Notepad.

There's a few reasons why stability can be important. One is that, if two records don't need to be swapped by swapping them you can cause a memory update, a page is marked dirty, and needs to be re-written to disk (or another slow medium).

Adding to olliej's answer, you can convert from an int back to a string with NSNumber's stringValue:

[[NSNumber numberWithInt:myInt] stringValue]

stringValue on an NSNumber invokes descriptionWithLocale:nil, giving you a localized string representation of value. I'm not sure if [NSString stringWithFormat:@"%d",myInt] will give you a properly localized reprsentation of myInt.

I get the simple solution:

 <button id="btn1" onclick="sendData(20)">ClickMe</button>

<script>
   var id; // global variable
   function sendData(valueId){
     id = valueId;
   }
   $("#btn1").click(function(){
        alert(id);
     });
</script>

My mean is that pass the value onclick event to the javascript function sendData(), initialize to the variable and take it by the jquery event handler method.

This is possible since at first sendData(valueid) gets called and initialize the value. Then after jquery event get's executed and use that value.

This is the straight forward solution and For Detail solution go Here.

You can also configure directly on the file ..sqldeveloper\ide\bin\ide.conf:

Just add the JVM Option:

AddVMOption -Duser.language=en

The file will be like this:

If you use request.getPathInfo() inside a Filter, you always seem to get null (at least with jetty).

This terse invalid bug + response alludes to the issue I think:

https://issues.apache.org/bugzilla/show_bug.cgi?id=28323

I suspect it is related to the fact that filters run before the servlet gets the request. It may be a container bug, or expected behaviour that I haven't been able to identify.

The contextPath is available though, so fforws solution works even in filters. I don't like having to do it by hand, but the implementation is broken or

Anywhere in one compilation unit (usually a .cpp file) would do:

foo.h

class foo {
    static const string s; // Can never be initialized here.
    static const char* cs; // Same with C strings.

    static const int i = 3; // Integral types can be initialized here (*)...
    static const int j; //     ... OR in cpp.
};

foo.cpp

#include "foo.h"
const string foo::s = "foo string";
const char* foo::cs = "foo C string";
// No definition for i. (*)
const int foo::j = 4;

(*) According to the standards you must define i outside of the class definition (like j is) if it is used in code other than just integral constant expressions. See David's comment below for details.
