I wrote a program with wpf and used Database for showing images and this is my code:

SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
                                      Initial Catalog=Payam;
                                      Integrated Security=True");

SqlDataAdapter da = new SqlDataAdapter("select * from news", con);

DataTable dt = new DataTable();
da.Fill(dt);

string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;

Another answer: There's a bookmarklet called ReCSS. I haven't used it extensively, but seems to work.

There's a bookmarklet on that page to drag and drop onto your address bar (Can't seem to make one here). In case that's broke, here's the code:

javascript:void(function()%7Bvar%20i,a,s;a=document.getElementsByTagName('link');for(i=0;i%3Ca.length;i++)%7Bs=a[i];if(s.rel.toLowerCase().indexOf('stylesheet')%3E=0&&s.href)%20%7Bvar%20h=s.href.replace(/(&%7C%5C?)forceReload=%5Cd%20/,'');s.href=h%20(h.indexOf('?')%3E=0?'&':'?')%20'forceReload='%20(new%20Date().valueOf())%7D%7D%7D)();

You should use getActivity() to launch activities from fragments

Intent intent = new Intent(getActivity(), mFragmentFavorite.class);
startActivity(intent);

Also, you should be naming classes with caps: MFragmentActivity instead of mFragmentActivity.

Linux specific, TLDR:

1. backtrace in glibc produces accurate stacktraces only when -lunwind is linked (undocumented platform-specific feature).
2. To output function name, source file and line number use #include <elfutils/libdwfl.h> (this library is documented only in its header file). backtrace_symbols and backtrace_symbolsd_fd are least informative.

On modern Linux your can get the stacktrace addresses using function backtrace. The undocumented way to make backtrace produce more accurate addresses on popular platforms is to link with -lunwind (libunwind-dev on Ubuntu 18.04) (see the example output below). backtrace uses function _Unwind_Backtrace and by default the latter comes from libgcc_s.so.1 and that implementation is most portable. When -lunwind is linked it provides a more accurate version of _Unwind_Backtrace but this library is less portable (see supported architectures in libunwind/src).

Unfortunately, the companion backtrace_symbolsd and backtrace_symbols_fd functions have not been able to resolve the stacktrace addresses to function names with source file name and line number for probably a decade now (see the example output below).

However, there is another method to resolve addresses to symbols and it produces the most useful traces with function name, source file and line number. The method is to #include <elfutils/libdwfl.h>and link with -ldw (libdw-dev on Ubuntu 18.04).

In a production version (as well as C language version) you may like to make this code extra robust by replacing boost::core::demangle, std::string and std::cout with their underlying calls.

You can also override __cxa_throw to capture the stacktrace when an exception is thrown and print it when the exception is caught. By the time it enters catch block the stack has been unwound, so it is too late to call backtrace, and this is why the stack must be captured on throw which is implemented by function __cxa_throw. Note that in a multi-threaded program __cxa_throw can be called simultaneously by multiple threads, so that if it captures the stacktrace into a global array that must be thread_local.

If you are using WL 10 use the following:

org.hibernate.dialect.Oracle10gDialect

You could use the Any() extension method. The following seems to work for me.

XStreamingElement root = new XStreamingElement("Results",
                from el in StreamProductItem(file)
                where fieldsToSearch.Any(s => el.Element(s) != null && el.Element(s).Value.Contains(searchTerm))
                select fieldsToReturn.Select(r => (r == "product") ? el : el.Element(r))
            );
            Console.WriteLine(root.ToString());

Where 'fieldsToSearch' and 'fieldsToReturn' are both List objects.

SQL has no built in notion of order, so you need to order by some column for this to be meaningful. Something like this:

select t1.value - t2.value from table t1, table t2 
where t1.primaryKey = t2.primaryKey - 1

If you know how to order things but not how to get the previous value given the current one (EG, you want to order alphabetically) then I don't know of a way to do that in standard SQL, but most SQL implementations will have extensions to do it.

Here is a way for SQL server that works if you can order rows such that each one is distinct:

select  rank() OVER (ORDER BY id) as 'Rank', value into temp1 from t

select t1.value - t2.value from temp1 t1, temp1 t2 
where t1.Rank = t2.Rank - 1

drop table temp1

If you need to break ties, you can add as many columns as necessary to the ORDER BY.

WSDL act as an interface between sender and receiver.
SOAP message is request and response in xml format.

comparing with java RMI

WSDL is the interface class
SOAP message is marshaled request and response message.

During the focus event you can scroll past the document height and magically the window.innerHeight is reduced by the height of the virtual keyboard. Note that the size of the virtual keyboard is different for landscape vs. portrait orientations so you'll need to redetect it when it changes. I would advise against remembering these values as the user could connect/disconnect a bluetooth keyboard at any time.

var element = document.getElementById("element"); // the input field
var focused = false;

var virtualKeyboardHeight = function () {
    var sx = document.body.scrollLeft, sy = document.body.scrollTop;
    var naturalHeight = window.innerHeight;
    window.scrollTo(sx, document.body.scrollHeight);
    var keyboardHeight = naturalHeight - window.innerHeight;
    window.scrollTo(sx, sy);
    return keyboardHeight;
};

element.onfocus = function () {
    focused = true;
    setTimeout(function() { 
        element.value = "keyboardHeight = " + virtualKeyboardHeight() 
    }, 1); // to allow for orientation scrolling
};

window.onresize = function () {
    if (focused) {
        element.value = "keyboardHeight = " + virtualKeyboardHeight();
    }
};

element.onblur = function () {
    focused = false;
};

Note that when the user is using a bluetooth keyboard, the keyboardHeight is 44 which is the height of the [previous][next] toolbar.

There is a tiny bit of flicker when you do this detection, but it doesn't seem possible to avoid it.

Just put your globals in the file you are importing.

To get the hex code for all the characters: http://asciitable.com/

As previously stated, it's not directly possible, but you can set up Apache or nginx + SSL on a EC2 instance, CNAME your desired domain to that, and reverse-proxy to the (non-custom domain) S3 URLs.

You can remove the blue outline by using outline: none.

However, I would highly recommend styling your focus states too. This is to help users who are visually impaired.

Check out: http://www.w3.org/TR/2008/REC-WCAG20-20081211/#navigation-mechanisms-focus-visible. More reading here: http://outlinenone.com

Instead of using the % unit – the width/height of another element – you should use vh and vw.
Your code would be:

your table {
  width: 100vw;
  height: 100vh;
}

But, if the document is smaller than 100vh or 100vw, then you need to set the size to the document's size.

(table).style.width = window.innerWidth;
(table).style.height = window.innerHeight;

This is a more efficient version of the solution from @Kramb. The existence check is redundant as the update where clause already handles this. Instead you just grab the rowcount and compare to batchsize.

Also note @Kramb solution didn't filter out already updated rows from the next iteration hence it would be an infinite loop.

Also uses the modern batch size syntax instead of using rowcount.

DECLARE @batchSize INT, @rowsUpdated INT
SET @batchSize = 1000;
SET @rowsUpdated = @batchSize; -- Initialise for the while loop entry

WHILE (@batchSize = @rowsUpdated)
BEGIN
    UPDATE TOP (@batchSize) TableName
    SET Value = 'abc1'
    WHERE Parameter1 = 'abc' AND Parameter2 = 123 and Value <> 'abc1';

    SET @rowsUpdated = @@ROWCOUNT;
END

Hiya demo http://jsfiddle.net/LYTbc/

this is a reference to the DOM element, so you can wrap it directly.

attr api: http://api.jquery.com/attr/

The .attr() method gets the attribute value for only the first element in the matched set.

have a nice one, cheers!

code

$(document).ready(function () {
    $(".inputs").click(function () {
         alert(this.id);

        alert(" or " + $(this).attr("id"));

    });

});?

import inspect
def s(template, **kwargs):
    "Usage: s(string, **locals())"
    if not kwargs:
        frame = inspect.currentframe()
        try:
            kwargs = frame.f_back.f_locals
        finally:
            del frame
        if not kwargs:
            kwargs = globals()
    return template.format(**kwargs)

Usage:

a = 123
s('{a}', locals()) # print '123'
s('{a}') # it is equal to the above statement: print '123'
s('{b}') # raise an KeyError: b variable not found

PS: performance may be a problem. This is useful for local scripts, not for production logs.

Duplicated:

• Python string formatting: % vs. .format

• What is the Python equivalent of embedding an expression in a string? (ie. "#{expr}" in Ruby)

• What is Ruby equivalent of Python's `s= "hello, %s. Where is %s?" % ("John","Mary")`

• Is there a Python equivalent to Ruby's string interpolation?

I got Darin's solution working eventually but made a few mistakes first which resulted in a problem similar to David (in the comments below Darin's solution) where the result was posting to a new page.

Because I had to do something with the form after the method returned, I stored it for later use:

var form = $(this);

However, this variable did not have the "action" or "method" properties which are used in the ajax call.

$(document).on("submit", "form", function (event) {
    var form = $(this);

    if (form.valid()) {
        $.ajax({
            url: form.action, // Not available to 'form' variable
            type: form.method,  // Not available to 'form' variable
            data: form.serialize(),
            success: function (html) {
                // Do something with the returned html.
            }
        });
    }

    event.preventDefault();
});

Instead you need to use the "this" variable:

$.ajax({
    url: this.action, 
    type: this.method,
    data: $(this).serialize(),
    success: function (html) {
        // Do something with the returned html.
    }
});

You can see the default value in Chrome in this link

int64_t g_used_idle_socket_timeout_s = 300 // 5 minutes

In Chrome, as far as I know, there isn't an easy way (as Firefox do) to change the timeout value.

Just a modified version of GregM's answer:

set folder="C:\test"
cd /D %folder%
if NOT %errorlevel% == 0 (exit /b 1)
echo Entire content of %cd% will be deleted. Press Ctrl-C to abort
pause

REM First the directories /ad option of dir
for /F "delims=" %%i in ('dir /b /ad') do (echo rmdir "%%i" /s/q)

REM Now the files /a-d option of dir
for /F "delims=" %%i in ('dir /b /a-d') do (echo del "%%i" /q)

REM To deactivate simulation mode remove the word 'echo' before 'rmdir' and 'del'.

You can either loop through the rows with a cursor and append to a field in a temp table, or you could use the COALESCE function to concatenate the fields.

The reason everyone always says to avoid System.gc() is that it is a pretty good indicator of fundamentally broken code. Any code that depends on it for correctness is certainly broken; any that rely on it for performance are most likely broken.

You don't know what sort of garbage collector you are running under. There are certainly some that do not "stop the world" as you assert, but some JVMs aren't that smart or for various reasons (perhaps they are on a phone?) don't do it. You don't know what it's going to do.

Also, it's not guaranteed to do anything. The JVM may just entirely ignore your request.

The combination of "you don't know what it will do," "you don't know if it will even help," and "you shouldn't need to call it anyway" are why people are so forceful in saying that generally you shouldn't call it. I think it's a case of "if you need to ask whether you should be using this, you shouldn't"

EDIT to address a few concerns from the other thread:

After reading the thread you linked, there's a few more things I'd like to point out. First, someone suggested that calling gc() may return memory to the system. That's certainly not necessarily true - the Java heap itself grows independently of Java allocations.

As in, the JVM will hold memory (many tens of megabytes) and grow the heap as necessary. It doesn't necessarily return that memory to the system even when you free Java objects; it is perfectly free to hold on to the allocated memory to use for future Java allocations.

To show that it's possible that System.gc() does nothing, view:

http://bugs.sun.com/view_bug.do?bug_id=6668279

and in particular that there's a -XX:DisableExplicitGC VM option.

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

My understanding of SQLiteDatabase APIs is that in case you have a multi threaded application, you cannot afford to have more than a 1 SQLiteDatabase object pointing to a single database.

The object definitely can be created but the inserts/updates fail if different threads/processes (too) start using different SQLiteDatabase objects (like how we use in JDBC Connection).

The only solution here is to stick with 1 SQLiteDatabase objects and whenever a startTransaction() is used in more than 1 thread, Android manages the locking across different threads and allows only 1 thread at a time to have exclusive update access.

Also you can do "Reads" from the database and use the same SQLiteDatabase object in a different thread (while another thread writes) and there would never be database corruption i.e "read thread" wouldn't read the data from the database till the "write thread" commits the data although both use the same SQLiteDatabase object.

This is different from how connection object is in JDBC where if you pass around (use the same) the connection object between read and write threads then we would likely be printing uncommitted data too.

In my enterprise application, I try to use conditional checks so that the UI Thread never have to wait, while the BG thread holds the SQLiteDatabase object (exclusively). I try to predict UI Actions and defer BG thread from running for 'x' seconds. Also one can maintain PriorityQueue to manage handing out SQLiteDatabase Connection objects so that the UI Thread gets it first.

Value exactly equal to 123:

jQuery("#attached_docs[value='123']")

You should assign an array of char pointers, and then, for each pointer assign enough memory for the string:

char **orderedIds;

orderedIds = malloc(variableNumberOfElements * sizeof(char*));
for (int i = 0; i < variableNumberOfElements; i++)
    orderedIds[i] = malloc((ID_LEN+1) * sizeof(char)); // yeah, I know sizeof(char) is 1, but to make it clear...

Seems like a good way to me. Although you perform many mallocs, you clearly assign memory for a specific string, and you can free one block of memory without freeing the whole "string array"

Listen to the change event.

input.onchange = function(e) { 
  ..
};

Use the -S switch

g++ -S main.cpp

or also with gcc

gcc -S main.c

Also see this

Your submit button doesn't have a name. Add name="submit" to your submit button.

If you view source on the form in the browser, you'll see how it submits to self - the form's action attribute will contain the name of the current script - therefore when the form submits, it submits to itself. Edit for vanity sake!

You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.

I had problems with the relative source in Silverlight. After searching and reading I did not find a suitable solution without using some additional Binding library. But, here is another approach for gaining access to the parent DataContext by directly referencing an element of which you know the data context. It uses Binding ElementName and works quite well, as long as you respect your own naming and don't have heavy reuse of templates/styles across components:

<ItemsControl x:Name="level1Lister" ItemsSource={Binding MyLevel1List}>
  <ItemsControl.ItemTemplate>
    <DataTemplate>
      <Button Content={Binding MyLevel2Property}
              Command={Binding ElementName=level1Lister,
                       Path=DataContext.MyLevel1Command}
              CommandParameter={Binding MyLevel2Property}>
      </Button>
    <DataTemplate>
  <ItemsControl.ItemTemplate>
</ItemsControl>

This also works if you put the button into Style/Template:

<Border.Resources>
  <Style x:Key="buttonStyle" TargetType="Button">
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="Button">
          <Button Command={Binding ElementName=level1Lister,
                                   Path=DataContext.MyLevel1Command}
                  CommandParameter={Binding MyLevel2Property}>
               <ContentPresenter/>
          </Button>
        </ControlTemplate>
      </Setter.Value>
    </Setter>

At first I thought that the x:Names of parent elements are not accessible from within a templated item, but since I found no better solution, I just tried, and it works fine.

there is a easy way: 1. using website's web.config 2. in "staticContent" section remove specific fileExtension and add mimeMap 3. add "clientCache"

<configuration>
  <system.webServer>
    <urlCompression doStaticCompression="true" doDynamicCompression="true" />
    <staticContent>
      <remove fileExtension=".ipa" />
      <remove fileExtension=".apk" />
      <mimeMap fileExtension=".ipa" mimeType="application/iphone" />
      <mimeMap fileExtension=".apk" mimeType="application/vnd.android.package-archive" />
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="777.00:00:00" />
    </staticContent>
  </system.webServer>
</configuration>

These posts apparently are in the wrong order! This is #1 in a series of 3 posts. Sorry.

In attempting to use Lie Ryan's code, I had problems retrieving stored information. The vector's elements are not stored contiguously,as you can see by "cheating" a bit and storing the pointer to each element's address (which of course defeats the purpose of the dynamic array concept) and examining them.

With a bit of tinkering, via:

ss_vector* vector; // pull this out to be a global vector

// Then add the following to attempt to recover stored values.

int return_id_value(int i,apple* aa) // given ptr to component,return data item
{   printf("showing apple[%i].id = %i and  other_id=%i\n",i,aa->id,aa->other_id);
    return(aa->id);
}

int Test(void)  // Used to be "main" in the example
{   apple* aa[10]; // stored array element addresses
    vector = ss_init_vector(sizeof(apple));
    // inserting some items
    for (int i = 0; i < 10; i++)
    {   aa[i]=init_apple(i);
        printf("apple id=%i and  other_id=%i\n",aa[i]->id,aa[i]->other_id);
        ss_vector_append(vector, aa[i]);
     }   
 // report the number of components
 printf("nmbr of components in vector = %i\n",(int)vector->size);
 printf(".*.*array access.*.component[5] = %i\n",return_id_value(5,aa[5]));
 printf("components of size %i\n",(int)sizeof(apple));
 printf("\n....pointer initial access...component[0] = %i\n",return_id_value(0,(apple *)&vector[0]));
 //.............etc..., followed by
 for (int i = 0; i < 10; i++)
 {   printf("apple[%i].id = %i at address %i, delta=%i\n",i,    return_id_value(i,aa[i]) ,(int)aa[i],(int)(aa[i]-aa[i+1]));
 }   
// don't forget to free it
ss_vector_free(vector);
return 0;
}

It's possible to access each array element without problems, as long as you know its address, so I guess I'll try adding a "next" element and use this as a linked list. Surely there are better options, though. Please advise.

A StringBuffer or its younger and faster brother StringBuilder is preferred whenever you're going do to a lot of string concatenations in flavor of

string += newString;

or equivalently

string = string + newString;

because the above constructs implicitly creates new string everytime which will be a huge performance and drop. A StringBuffer / StringBuilder is under the hoods best to be compared with a dynamically expansible List<Character>.

I solved the problem by saving the fragments in SparceArray:

public abstract class SaveFragmentsPagerAdapter extends FragmentPagerAdapter {

    SparseArray<Fragment> fragments = new SparseArray<>();

    public SaveFragmentsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Fragment fragment = (Fragment) super.instantiateItem(container, position);
        fragments.append(position, fragment);
        return fragment;
    }

    @Nullable
    public Fragment getFragmentByPosition(int position){
        return fragments.get(position);
    }

}

If you serialize the object that you have, you can do something like this by using "System.Xml.Serialization.XmlAttributeAttribute" on every property that you want to be specified as an attribute in your model, which in my opinion is a lot easier:

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public class UserNode
{
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string userName { get; set; }

    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string passWord { get; set; }

    public int Age { get; set; }
    public string Name { get; set; }         
 }

 public class LoginNode 
 {
    public UserNode id { get; set; }
 }

Then you just serialize to XML an instance of LoginNode called "Login", and that's it!

Here you have a few examples to serialize and object to XML, but I would suggest to create an extension method in order to be reusable for other objects.

app.js

$("button").click( function() {
 $.getJSON( "article.json", function(obj) {
  $.each(obj, function(key, value) {
         $("ul").append("<li>"+value.name+"'s age is : "+value.age+"</li>");
  });
 });
});

function onRequest(request,response){
  if(request.method == 'GET' && request.url == '/') {
          response.writeHead(200,{"Content-Type":"text/html"});
          fs.createReadStream("./index.html").pipe(response);
  } else if(request.method == 'GET' && request.url == '/jquery-3.2.0.min.js') {
          response.writeHead(200,{"Content-Type":"text/javascript"});
          fs.createReadStream("./jquery-3.2.0.min.js").pipe(response);
  } else if(request.method == 'GET' && request.url == '/app.js') {
          response.writeHead(200,{"Content-Type":"text/javascript"});
          fs.createReadStream("./app.js").pipe(response);
  }
  else if(request.method == 'GET' && request.url == '/article.json') {

This is my running one https://github.com/surya4/jquery-json.

it is similar to jason lee as he mentioned earlier:

in Jupyter notebook, you can access the current working directory by

pwd()

or by import OS from library and running os.getcwd()

i.e. for example

In[ ]: import os

       os.getcwd( )

out[ ]: :c\\users\\admin\\Desktop\\python    

        (#This is my working directory)

Changing Working Directory

For changing the Working Directory (much more similar to current W.d just you need to change from os.getcwd() to os.chdir('desired location')

In[ ]: import os

       os.chdir('c:user/chethan/Desktop')        (#This is where i want to update my w.d, 
                                                  like that choose your desired location)
out[  ]: 'c:user\\chethan\\Desktop'

Python, include all files under a directory:

For newbies who just can't get it to work who need their hands held.

1. Make a folder /home/el/foo and make a file main.py under /home/el/foo Put this code in there:

   from hellokitty import *
   spam.spamfunc()
   ham.hamfunc()
   

2. Make a directory /home/el/foo/hellokitty

3. Make a file __init__.py under /home/el/foo/hellokitty and put this code in there:

   __all__ = ["spam", "ham"]
   

4. Make two python files: spam.py and ham.py under /home/el/foo/hellokitty

5. Define a function inside spam.py:

   def spamfunc():
     print("Spammity spam")
   

6. Define a function inside ham.py:

   def hamfunc():
     print("Upgrade from baloney")
   

7. Run it:

   el@apollo:/home/el/foo$ python main.py 
   spammity spam
   Upgrade from baloney
   

int belongs to System.ValueType and cannot have null as a value. When dealing with databases or other types where the elements can have a null value, it might be useful to check if the element is null. That is when int? comes into play. int? is a nullable type which can have values ranging from -2147483648 to 2147483648 and null.

To fully overload it you also need to implement the __setitem__and __delitem__ methods.

edit

I almost forgot... if you want to completely emulate a list, you also need __getslice__, __setslice__ and __delslice__.

There are all documented in http://docs.python.org/reference/datamodel.html

The root problem here seems that iOS8 safari won't hide the address bar when scrolling down if the content is equal or less than the viewport.

As you found out already, adding some padding at the bottom gets around this issue:

html {
    /* enough space to scroll up to get fullscreen on iOS8 */
    padding-bottom: 80px;
}

// sort of emulate safari's "bounce back to top" scroll
window.addEventListener('scroll', function(ev) {
    // avoids scrolling when the focused element is e.g. an input
    if (
        !document.activeElement
        || document.activeElement === document.body
    ) {
        document.body.scrollIntoViewIfNeeded(true);
    }
});

The above css should be conditionally applied, for example with UA sniffing adding a gt-ios8 class to <html>.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

As an aside to what folks have been posting here, I've heard that concatenation can be much faster than join in modern javascript vms. Meaning:

var a = 
[ "hey man, this is on a line",
  "and this is on another",
  "and this is on a third"
].join('\n');

Will be slower than:

var a = "hey man, this is on a line\n" + 
        "and this is on another\n" +
        "and this is on a third";    

In certain cases. http://jsperf.com/string-concat-versus-array-join/3

As another aside, I find this one of the more appealing features in Coffeescript. Yes, yes, I know, haters gonna hate.

html = '''
       <strong>
         cup of coffeescript
       </strong>
       '''

Its especially nice for html snippets. I'm not saying its a reason to use it, but I do wish it would land in ecma land :-(.

you can use this to get the data of the last 30 days based on a column.

WHERE DATEDIFF(dateColumn,CURRENT_TIMESTAMP) BETWEEN 0 AND 30

As for me it was enough to copy all property fields from the base class to the parent like this:

using System.Reflection;

public static ChildClass Clone(BaseClass b)
{
    ChildClass p = new ChildClass(...);

    // Getting properties of base class

    PropertyInfo[] properties = typeof(BaseClass).GetProperties();

    // Copy all properties to parent class

    foreach (PropertyInfo pi in properties)
    {
        if (pi.CanWrite)
            pi.SetValue(p, pi.GetValue(b, null), null);
    }

    return p;
}

In addition to configuration changes on your WWW server to handle the new subdomain, your code would need to be making changes to your DNS records. So, unless you're running your own BIND (or similar), you'll need to figure out how to access your name server provider's configuration. If they don't offer some sort of API, this might get tricky.

Update: yes, I would check with your registrar if they're also providing the name server service (as is often the case). I've never explored this option before but I suspect most of the consumer registrars do not. I Googled for GoDaddy APIs and GoDaddy DNS APIs but wasn't able to turn anything up, so I guess the best option would be to check out the online help with your provider, and if that doesn't answer the question, get a hold of their support staff.

To improve Darin's answer, it can be bit shorter:

public class UniqueFileName : ValidationAttribute
{
    private readonly NewsService _newsService = new NewsService();

    public override bool IsValid(object value)
    {
        if (value == null) { return false; }

        var file = (HttpPostedFile) value;

        return _newsService.IsFileNameUnique(file.FileName);
    }
}

Model:

[UniqueFileName(ErrorMessage = "This file name is not unique.")]

Do note that an error message is required, otherwise the error will be empty.

Conditionals work if they're structured correctly, I ran into this issue and figured it out.

For conditionals, the tag before else has to be paired with the end tag of the previous if otherwise the statements will evaluate separately and produce an error.

ERROR!

<% if(true){ %>
   <h1>foo</h1>
<% } %>
<% else{ %>
   <h1>bar</h1>
 <% } %>

Correct

<% if(true){ %>
   <h1>foo</h1>
 <% } else{ %>  
   <h1>bar</h1>
<% } %>

hope this helped.

Well I would atleast clean it up as follows:

print "%.2f kg = %.2f lb = %.2f gal = %.2f l" % (var1, var2, var3, var4)

Or you could try to avoid some temps with

A = M.view(np.ndarray)
A.shape = -1

Use PUT for updating incomplete/partial resource.

You can accept jObject as parameter and parse its value to update the resource.

Below is the function which you can use as a reference :

public IHttpActionResult Put(int id, JObject partialObject)
{
    Dictionary<string, string> dictionaryObject = new Dictionary<string, string>();

    foreach (JProperty property in json.Properties())
    {
        dictionaryObject.Add(property.Name.ToString(), property.Value.ToString());
    }

    int id = Convert.ToInt32(dictionaryObject["id"]);
    DateTime startTime = Convert.ToDateTime(orderInsert["AppointmentDateTime"]);            
    Boolean isGroup = Convert.ToBoolean(dictionaryObject["IsGroup"]);

    //Call function to update resource
    update(id, startTime, isGroup);

    return Ok(appointmentModelList);
}

I didn't find the package of the most voted answer in my Python 3 dist.

I had the same problem and solved it installing the module pywin32:

In a normal python:

pip install pywin32

In anaconda:

conda install pywin32

My python installation (Intel® Distribution for Python) had some kind of dependency problem and was giving this error. After installing this module it stopped appearing.

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE 0 END AS YOUR_QUERY_ANSWERED

above will return values

however below query wont work

DECLARE @INPUT VARCHAR(5) = '0.12',@INPUT_1 VARCHAR(5)='0.12x';
select CONVERT(float, @INPUT) YOUR_QUERY ,
case when isnumeric(@INPUT_1)=1 THEN CONVERT(float, @INPUT_1) ELSE **@INPUT_1** END AS YOUR_QUERY_ANSWERED

as @INPUT_1 actually has varchar in it.

So your output column must have a varchar in it.

Like KingCronus mentioned in the comments you can use the row class to make the list or heading on its own line. You could use the row class on either or both elements:

Most answers here forget the obvious culprit why recursion is often slower than iterative solutions. It's linked with the build up and tear down of stack frames but is not exactly that. It's generally a big difference in the storage of the auto variable for each recursion. In an iterative algorithm with a loop, the variables are often held in registers and even if they spill, they will reside in the Level 1 cache. In a recursive algorithm, all intermediary states of the variable are stored on the stack, meaning they will engender many more spills to memory. This means that even if it makes the same amount of operations, it will have a lot memory accesses in the hot loop and what makes it worse, these memory operations have a lousy reuse rate making the caches less effective.

TL;DR recursive algorithms have generally a worse cache behavior than iterative ones.

In Visual Studio 2015, this is how you do it.

If you want to automatically include all descendant files below a specific folder:

<Content Include="Path\To\Folder\**" />

This can be restricted to include only files within the path specified:

<Content Include="Path\To\Folder\*.*" />

Or even only files with a specified extension:

<Content Include="Path\To\Folder\*.jpg" >

- First we must know that the diff bet static and non static methods 
is differ from static and non static variables : 

- this code explain static method - non static method and what is the diff 

    public class MyClass {
        static {
            System.out.println("this is static routine ... ");

        }
          public static void foo(){
            System.out.println("this is static method ");
        }

        public void blabla(){

         System.out.println("this is non static method ");

Vue by default ships with the v-html directive to show it, you bind it onto the element itself rather than using the normal moustache binding for string variables.

So for your specific example you would need:

<div id="logapp">    
    <table>
        <tbody>
            <tr v-repeat="logs">
                <td v-html="fail"></td>
                <td v-html="type"></td>
                <td v-html="description"></td>
                <td v-html="stamp"></td>
                <td v-html="id"></td>
            </tr>
        </tbody>
    </table>
</div>

If you are using Dev C++ then your .exe or mean to say your program already running and you are trying to run it again.

Based on this answer from @Guilherme Ferreira you can trigger the parseFloat method every time the field changes. Therefore the value always shows two decimal places, even if a user changes the value by manual typing a number.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<script type="text/javascript">_x000D_
    $(document).ready(function () {_x000D_
        $(".floatNumberField").change(function() {_x000D_
            $(this).val(parseFloat($(this).val()).toFixed(2));_x000D_
        });_x000D_
    });_x000D_
</script>_x000D_
_x000D_
<input type="number" class="floatNumberField" value="0.00" placeholder="0.00" step="0.01" />

I hade same problem then i fixed like this

change "text/javascript"

to

type="application/json"

You can use command ng serve -c dev for development environment ng serve -c prod for production environment

while building also same applies. You can use ng build -c dev for dev build

Can you use Boost String Algo? http://www.boost.org/doc/libs/1_35_0/doc/html/string_algo/usage.html#id1290573

erase_all(str, " "); 

I have try a lot with different approaches. And finally, I improve one of the methods. First you need to create a separate collection and save there all events. Second you need to create a new lambda to be triggered by time. This lambda will Count events in event collection and clear event documents. Code details in article. https://medium.com/@ihor.malaniuk/how-to-count-documents-in-google-cloud-firestore-b0e65863aeca

The problem for me was that SSRS purposely treats your white space as if you intend it be honored:

As well as white space, make sure there is no right margin.

The better pattern is to create a standalone BroadcastReceiver. This insures that your app can respond to the broadcast, whether or not the Service is running. In fact, using this pattern may remove the need for a constant-running Service altogether.

Register the BroadcastReceiver in your Manifest, and create a separate class/file for it.

Eg:

<receiver android:name=".FooReceiver" >
    <intent-filter >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

When the receiver runs, you simply pass an Intent (Bundle) to the Service, and respond to it in onStartCommand().

Eg:

public class FooReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // do your work quickly!
        // then call context.startService();
    }   
}

With ES6 arrow functions it will be like this:

//Let's say we have these cars
let cars = [ { brand: 'Porsche', top_speed: 260 },
  { brand: 'Benz', top_speed: 110 },
  { brand: 'Fiat', top_speed: 90 },
  { brand: 'Aston Martin', top_speed: 70 } ]

Array.prototype.sort() can accept a comparator function (here I used arrow notation, but ordinary functions work the same):

let sortedByBrand = [...cars].sort((first, second) => first.brand > second.brand)

// [ { brand: 'Aston Martin', top_speed: 70 },
//   { brand: 'Benz', top_speed: 110 },
//   { brand: 'Fiat', top_speed: 90 },
//   { brand: 'Porsche', top_speed: 260 } ]

The above approach copies the contents of cars array into a new one and sorts it alphabetically based on brand names. Similarly, you can pass a different function:

let sortedBySpeed =[...cars].sort((first, second) => first.top_speed > second.top_speed)

//[ { brand: 'Aston Martin', top_speed: 70 },
//  { brand: 'Fiat', top_speed: 90 },
//  { brand: 'Benz', top_speed: 110 },
//  { brand: 'Porsche', top_speed: 260 } ]

If you don't mind mutating the orginal array cars.sort(comparatorFunction) will do the trick.

Just invoke ruby XXXXX.rb in terminal, if the interpreter is in your $PATH variable.

( this can hardly be a rails thing, until you have it running. )

Setting 700 to .ssh and 600 to authorized_keys solved the issue.

chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys

From all my searching around, I strongly say that the most practical, accurate and free data source is provided by GeoNames.

You can access their data in 2 ways:

1. The easy way through their free web services.
2. Import their free text files into Database tables and use the data in any way you wish. This method offers much greater flexibility and have found that this method is better.

Simply SELECT @@system_time_zone;

Returns PST (or whatever is relevant to your system).

If you're trying to determine the session timezone you can use this query:
SELECT IF(@@session.time_zone = 'SYSTEM', @@system_time_zone, @@session.time_zone);

Which will return the session timezone if it differs from the system timezone.

Try this:

Response.Redirect(Request.Url.AbsoluteUri);

Try following query:-

 SELECT table1.id 
 FROM table1 
 where table1.id 
 NOT IN (SELECT user_one
         FROM Table2
             UNION
         SELECT user_two
         FROM Table2)

Hope this helps you.

You can do like this

var name = "foo";_x000D_
var value = "Hello foos";_x000D_
eval("var "+name+" = '"+value+"';");_x000D_
alert(foo);

This solution is better because of no need to define the source model. But the name of the serializer field should be the same as the foreign key field name

class ItemSerializer(serializers.ModelSerializer):
    category = serializers.SlugRelatedField(read_only=True, slug_field='title')

    class Meta:
        model = Item
        fields = ('id', 'name', 'category')

Do C-b, :show which will show you all your current settings. /green, nnn will find you which properties have been set to green, the default. Do C-b, :set window-status-bg cyan and the bottom bar should change colour.

List available colours for tmux

You can tell more easily by the titles and the colours as they're actually set in your live session :show, than by searching through the man page, in my opinion. It is a very well-written man page when you have the time though.

If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf with a line like set window-status-bg -g cyan. Here's mine: https://gist.github.com/9083598

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Thank you Rob W for your answer.

I have been using this within a Cordova application to avoid having to load the API and so that I can easily control iframes which are loaded dynamically.

I always wanted the ability to be able to extract information from the iframe, such as the state (getPlayerState) and the time (getCurrentTime).

Rob W helped highlight how the API works using postMessage, but of course this only sends information in one direction, from our web page into the iframe. Accessing the getters requires us to listen for messages posted back to us from the iframe.

It took me some time to figure out how to tweak Rob W's answer to activate and listen to the messages returned by the iframe. I basically searched through the source code within the YouTube iframe until I found the code responsible for sending and receiving messages.

The key was changing the 'event' to 'listening', this basically gave access to all the methods which were designed to return values.

Below is my solution, please note that I have switched to 'listening' only when getters are requested, you can tweak the condition to include extra methods.

Note further that you can view all messages sent from the iframe by adding a console.log(e) to the window.onmessage. You will notice that once listening is activated you will receive constant updates which include the current time of the video. Calling getters such as getPlayerState will activate these constant updates but will only send a message involving the video state when the state has changed.

function callPlayer(iframe, func, args) {
    iframe=document.getElementById(iframe);
    var event = "command";
    if(func.indexOf('get')>-1){
        event = "listening";
    }

    if ( iframe&&iframe.src.indexOf('youtube.com/embed') !== -1) {
      iframe.contentWindow.postMessage( JSON.stringify({
          'event': event,
          'func': func,
          'args': args || []
      }), '*');
    }
}
window.onmessage = function(e){
    var data = JSON.parse(e.data);
    data = data.info;
    if(data.currentTime){
        console.log("The current time is "+data.currentTime);
    }
    if(data.playerState){
        console.log("The player state is "+data.playerState);
    }
}

following @tony's approach, changed the getTableHeight() function to

<div id="grid1" ui-grid="$ctrl.gridOptions" class="grid" ui-grid-auto-resize style="{{$ctrl.getTableHeight()}}"></div>

getTableHeight() {
    var offsetValue = 365;
    return "height: " + parseInt(window.innerHeight - offsetValue ) + "px!important";
}

the grid would have a dynamic height with regards to window height as well.

I would grab date.js or else you will need to roll your own formatting function.

This code snippet is working properly

There is a discussion on GitHub because of a question similar to this one: https://gist.github.com/1398757

You can use other projects for guidance, search in GitHub for:

• ThreeNodes.js - in my opinion, seems to have a specific structure not suitable for every project;
• lighter - an more simple structure, but lacks a bit of organization;

And finally, in a book (http://shop.oreilly.com/product/0636920025344.do) suggests this structure:

+-- index.html
+-- js/
¦   +-- main.js
¦   +-- models/
¦   +-- views/
¦   +-- collections/
¦   +-- templates/
¦   +-- libs/
¦       +-- backbone/
¦       +-- underscore/
¦       +-- ...
+-- css/
+-- ...

This is a lot simpler with .slideToggle():

I open the Play Store from my App with the following code:

            val uri: Uri = Uri.parse("market://details?id=$packageName")
            val goToMarket = Intent(Intent.ACTION_VIEW, uri)
            // To count with Play market backstack, After pressing back button, 
            // to taken back to our application, we need to add following flags to intent. 
            goToMarket.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY or
                    Intent.FLAG_ACTIVITY_NEW_DOCUMENT or
                    Intent.FLAG_ACTIVITY_MULTIPLE_TASK)
            try {
                startActivity(goToMarket)
            } catch (e: ActivityNotFoundException) {
                startActivity(Intent(Intent.ACTION_VIEW,
                        Uri.parse("http://play.google.com/store/apps/details?id=$packageName")))
            }

The easy way to change version is first to check your available version using nvm ls then select version from the list nvm use version

Depending on what you mean by "use them as Strings", you might not want to use an enum here. In most cases, the solution proposed by The Elite Gentleman will allow you to use them through their toString-methods, e.g. in System.out.println(STRING_ONE) or String s = "Hello "+STRING_TWO, but when you really need Strings (e.g. STRING_ONE.toLowerCase()), you might prefer defining them as constants:

public interface Strings{
  public static final String STRING_ONE = "ONE";
  public static final String STRING_TWO = "TWO";      
}

Do .libPaths(), close every R runing, check in the first directory, remove the zoo package restart R and install zoo again. Of course you need to have sufficient rights.

Useful tool for debugging java programs, it gives the number of threads and other relevant info on them:

jconsole <process-id>

Also for openCV in python you can do:

img = cv2.imread('myImage.jpg')
height, width, channels = img.shape 

1.First open your terminal

2.Then update your gem file with command

sudo gem install -n /usr/local/bin cocoapods

3.Then give your project path

cd /your project path 

4.Touch the podifle

touch podfile

5.Open your podfile

open -e podfile

6.It will open a podfile like a text edit. Then set your target. For example if you want to set up Google maps then your podfile should be like

use_frameworks!
target 'yourProjectName' do
    pod 'GoogleMaps'
end

7.Then install the pod

pod install

Ruby on rails uses :: for namespace resolution.

class User < ActiveRecord::Base

  VIDEOS_COUNT = 10
  Languages = { "English" => "en", "Spanish" => "es", "Mandarin Chinese" => "cn"}

end

To use it :

User::VIDEOS_COUNT
User::Languages
User::Languages.values_at("Spanish") => "en"

Also, other usage is : When using nested routes

OmniauthCallbacksController is defined under users.

And routed as:

devise_for :users, controllers: {omniauth_callbacks: "users/omniauth_callbacks"}


class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController

end

when I use the function

select dbo.decode(10>1 ,'yes' ,'no')

then say syntax error near '>'

Unfortunately, that does not get you around having the CASE clause in the SQL, since you would need it to convert the logical expression to a bit parameter to match the type of the first function argument:

create function decode(@var1 as bit, @var2 as nvarchar(100), @var3 as nvarchar(100))
returns nvarchar(100)
begin
return case when @var1 = 1 then @var2 else @var3 end;
end;

select dbo.decode(case when 10 > 1 then 1 else 0 end, 'Yes', 'No');

Try

this.router.navigate([], { 
  queryParams: {
    query: value
  }
});

will work for same route navigation other than single quotes.

How about:

(sleep 5; echo "Hello World") &

Mostly likely middle click your mouse.

Or try Shift + Insert.

It all depends on terminal used and X11-config for mouse.

If additional table doesn't fit, you can write your own function for translation.

The plus of sql function over case is, that you can use it in various places, and keep translation logic in one place.

in my case, i had the same problem while i try any git -- commands (eg git status) using windows cmd. so what i do is after installing git for window https://windows.github.com/ in the environmental variables, add the class path of the git on the "PATH" varaiable. usually the git will installed on C:/user/"username"/appdata/local/git/bin add this on the PATH in the environmental variable

and one more thing on the cmd go to your git repository or cd to where your clone are on your window usually they will be stored on the documents under github cd Document/Github/yourproject after that you can have any git commands

thank you

We can also use col-md-offset like this, it would save us from an extra divs code. So instead of three divs we can do by using only one div:

<div class="col-md-4 col-md-offset-4">Centered content</div>

With the first example, SetPrivateValue won't exist in the build if DEBUG is not defined, with the second example, calls to SetPrivateValue won't exist in the build if DEBUG is not defined.

With the first example, you'll have to wrap any calls to SetPrivateValue with #if DEBUG as well.

With the second example, the calls to SetPrivateValue will be omitted, but be aware that SetPrivateValue itself will still be compiled. This is useful if you're building a library, so an application referencing your library can still use your function (if the condition is met).

If you want to omit the calls and save the space of the callee, you could use a combination of the two techniques:

[System.Diagnostics.Conditional("DEBUG")]
public void SetPrivateValue(int value){
    #if DEBUG
    // method body here
    #endif
}

See this post How to execute angular controller function on page load?
For fast lookup:

// register controller in html
<div data-ng-controller="myCtrl" data-ng-init="init()"></div>

// in controller
$scope.init = function () {
    // check if there is query in url
    // and fire search in case its value is not empty
};

This way, You don't have to wait till document is ready.

The question bears re-reading. The actual question asked is not similar to vendor prefixes in CSS properties, where future-proofing and thinking about vendor support and official standards is appropriate. The actual question asked is more akin to choosing URL query parameter names. Nobody should care what they are. But name-spacing the custom ones is a perfectly valid -- and common, and correct -- thing to do.

Rationale:
It is about conventions among developers for custom, application-specific headers -- "data relevant to their account" -- which have nothing to do with vendors, standards bodies, or protocols to be implemented by third parties, except that the developer in question simply needs to avoid header names that may have other intended use by servers, proxies or clients. For this reason, the "X-Gzip/Gzip" and "X-Forwarded-For/Forwarded-For" examples given are moot. The question posed is about conventions in the context of a private API, akin to URL query parameter naming conventions. It's a matter of preference and name-spacing; concerns about "X-ClientDataFoo" being supported by any proxy or vendor without the "X" are clearly misplaced.

There's nothing special or magical about the "X-" prefix, but it helps to make it clear that it is a custom header. In fact, RFC-6648 et al help bolster the case for use of an "X-" prefix, because -- as vendors of HTTP clients and servers abandon the prefix -- your app-specific, private-API, personal-data-passing-mechanism is becoming even better-insulated against name-space collisions with the small number of official reserved header names. That said, my personal preference and recommendation is to go a step further and do e.g. "X-ACME-ClientDataFoo" (if your widget company is "ACME").

IMHO the IETF spec is insufficiently specific to answer the OP's question, because it fails to distinguish between completely different use cases: (A) vendors introducing new globally-applicable features like "Forwarded-For" on the one hand, vs. (B) app developers passing app-specific strings to/from client and server. The spec only concerns itself with the former, (A). The question here is whether there are conventions for (B). There are. They involve grouping the parameters together alphabetically, and separating them from the many standards-relevant headers of type (A). Using the "X-" or "X-ACME-" prefix is convenient and legitimate for (B), and does not conflict with (A). The more vendors stop using "X-" for (A), the more cleanly-distinct the (B) ones will become.

Example:
Google (who carry a bit of weight in the various standards bodies) are -- as of today, 20141102 in this slight edit to my answer -- currently using "X-Mod-Pagespeed" to indicate the version of their Apache module involved in transforming a given response. Is anyone really suggesting that Google should use "Mod-Pagespeed", without the "X-", and/or ask the IETF to bless its use?

Summary:
If you're using custom HTTP Headers (as a sometimes-appropriate alternative to cookies) within your app to pass data to/from your server, and these headers are, explicitly, NOT intended ever to be used outside the context of your application, name-spacing them with an "X-" or "X-FOO-" prefix is a reasonable, and common, convention.

way 1 :

Let we have java file test.java which contains main class testa now first we compile our java file simply as javac test.java we create file manifest.txt in same directory and we write Main-Class: mainclassname . e.g :

  Main-Class: testa

then we create jar file by this command :

  jar cvfm anyname.jar manifest.txt testa.class

then we run jar file by this command : java -jar anyname.jar

way 2 :

Let we have one package named one and every class are inside it. then we create jar file by this command :

  jar cf anyname.jar one

then we open manifest.txt inside directory META-INF in anyname.jar file and write

  Main-Class: one.mainclassname 

in third line., then we run jar file by this command :

  java -jar anyname.jar

to make jar file having more than one class file : jar cf anyname.jar one.class two.class three.class......

I just disable the Two-factor authentication and try again. It works for me.

EDIT: I understood this question wrong, but I will leave the awnser as more people might misunderstand the question and came for the awnser I supplied.

Use Excel Online (Google Sheets).. And install Power Tools for Google Sheets.. Then in Google Sheets go to Addons tab and start Power Tools. Then choose Randomize from Power Tools menu. Select Shuffle. Then select choices of your test in excel sheet. Then select Cells in each row and click Shuffle from Power Tools menu. This will shuffle each row's selected cells independently from one another.

Another method to try out. Also select could be replaced when you set the initial column into a Range object. Performance wise it helps.

Dim rng as Range

Set rng = WorkSheets(1).Range("A1") '-- you may change the sheet name according to yours.

'-- here is your loop
i = 1
Do
   '-- do something: e.g. show the address of the column that you are currently in
   Msgbox rng.offset(0,i).Address 
   i = i + 1
Loop Until i > 10

** Two methods to get the column name using column number**

• Split()

code

colName = Split(Range.Offset(0,i).Address, "$")(1)

• String manipulation:

code

Function myColName(colNum as Long) as String
    myColName = Left(Range(0, colNum).Address(False, False), _ 
    1 - (colNum > 10)) 
End Function 

You are more than likely missing $(IncludePath) within Properties->VC++ Directories->Include Directories. Adding this should make iostream and others visible again. You probably deleted it by mistake while setting up your program.

After careful consideration this dillema has a few different solutions:

Aggregate Everything Use an aggregate on each column to get the biggest or smallest field value. This is what I am doing since it takes 2 partially filled out records and "merges" the data.

http://sqlfiddle.com/#!3/59cde/1

SELECT
  UPPER(IDNo) AS user_id
, MAX(FirstName) AS name_first
, MAX(LastName) AS name_last
, MAX(entry) AS row_num
FROM people P
GROUP BY 
  IDNo

Get First (or Last record)

http://sqlfiddle.com/#!3/59cde/23

-- ------------------------------------------------------
-- Notes
-- entry: Auto-Number primary key some sort of unique PK is required for this method
-- IDNo:  Should be primary key in feed, but is not, we are making an upper case version
-- This gets the first entry to get last entry, change MIN() to MAX()
-- ------------------------------------------------------

SELECT 
   PC.user_id
  ,PData.FirstName
  ,PData.LastName
  ,PData.entry
FROM (
  SELECT 
      P2.user_id
     ,MIN(P2.entry) AS rownum
  FROM (
    SELECT
        UPPER(P.IDNo) AS user_id 
      , P.entry 
    FROM people P
  ) AS P2
  GROUP BY 
    P2.user_id
) AS PC
LEFT JOIN people PData
ON PData.entry = PC.rownum
ORDER BY 
   PData.entry

A nested dict is a dictionary within a dictionary. A very simple thing.

>>> d = {}
>>> d['dict1'] = {}
>>> d['dict1']['innerkey'] = 'value'
>>> d
{'dict1': {'innerkey': 'value'}}

You can also use a defaultdict from the collections package to facilitate creating nested dictionaries.

>>> import collections
>>> d = collections.defaultdict(dict)
>>> d['dict1']['innerkey'] = 'value'
>>> d  # currently a defaultdict type
defaultdict(<type 'dict'>, {'dict1': {'innerkey': 'value'}})
>>> dict(d)  # but is exactly like a normal dictionary.
{'dict1': {'innerkey': 'value'}}

You can populate that however you want.

I would recommend in your code something like the following:

d = {}  # can use defaultdict(dict) instead

for row in file_map:
    # derive row key from something 
    # when using defaultdict, we can skip the next step creating a dictionary on row_key
    d[row_key] = {} 
    for idx, col in enumerate(row):
        d[row_key][idx] = col

According to your comment:

may be above code is confusing the question. My problem in nutshell: I have 2 files a.csv b.csv, a.csv has 4 columns i j k l, b.csv also has these columns. i is kind of key columns for these csvs'. j k l column is empty in a.csv but populated in b.csv. I want to map values of j k l columns using 'i` as key column from b.csv to a.csv file

My suggestion would be something like this (without using defaultdict):

a_file = "path/to/a.csv"
b_file = "path/to/b.csv"

# read from file a.csv
with open(a_file) as f:
    # skip headers
    f.next()
    # get first colum as keys
    keys = (line.split(',')[0] for line in f) 

# create empty dictionary:
d = {}

# read from file b.csv
with open(b_file) as f:
    # gather headers except first key header
    headers = f.next().split(',')[1:]
    # iterate lines
    for line in f:
        # gather the colums
        cols = line.strip().split(',')
        # check to make sure this key should be mapped.
        if cols[0] not in keys:
            continue
        # add key to dict
        d[cols[0]] = dict(
            # inner keys are the header names, values are columns
            (headers[idx], v) for idx, v in enumerate(cols[1:]))

Please note though, that for parsing csv files there is a csv module.

usually when i work with remote location teams it is important for me that i have prior knowledge what change done by other teams in same file, before i follow git stages untrack-->staged-->commit for that i wrote an bash script which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on main branch

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | grep "modified" | awk "{print $2}" `
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool FETCH_HEAD $file ;
done

in above script i fetch remote main branch (not necessary its master branch)to FETCH_HEAD them make a list of my modified file only and compare modified files to git difftool

here many difftool supported by git, i configure 'Meld Diff Viewer' for good GUI comparison .

.card-img-top {

Contain will help in getting Complete Image displayed inside Card.

Adjust height "30vh" according to your need!

I think this method my solve your problem:

public static void attachFragment ( int fragmentHolderLayoutId, Fragment fragment, Context context, String tag ) {


    FragmentManager manager = ( (AppCompatActivity) context ).getSupportFragmentManager ();
    FragmentTransaction ft = manager.beginTransaction ();

    if (manager.findFragmentByTag ( tag ) == null) { // No fragment in backStack with same tag..
        ft.add ( fragmentHolderLayoutId, fragment, tag );
        ft.addToBackStack ( tag );
        ft.commit ();
    }
    else {
        ft.show ( manager.findFragmentByTag ( tag ) ).commit ();
    }
}

The solutions above are great for interactive use, where you can eyeball the result and weed out false positives that way.

False positives can occur if the executable itself happens to match, or any arguments that are not script names match - the likelihood is greater with scripts that have no filename extensions.

Here's a more robust solution for scripting, using a shell function:

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

Example use:

# List instance(s) of script "aa.sh" that are running.
getscript "aa.sh"  # -> (e.g.): 96112 bash /Users/jdoe/aa.sh

# Use in a test:
if getscript "aa.sh" >/dev/null; then
  echo RUNNING
fi

• Matching is case-sensitive (on macOS, you could add -i to the pgrep call to make it case-insensitive; on Linux, that is not an option.)
• The getscript function also works with full or partial paths that include the filename component; partial paths must not start with / and each component specified must be complete. The "fuller" the path specified, the lower the risk of false positives. Caveat: path matching will only work if the script was invoked with a path - this is generally true for scripts in the $PATH that are invoked directly.
• Even this function cannot rule out all false positives, as paths can have embedded spaces, yet neither ps nor pgrep reflect the original quoting applied to the command line. All the function guarantees is that any match is not the first token (which is the interpreter), and that it occurs as a separate word, optionally preceded by a path.
• Another approach to minimizing the risk of false positives could be to match the executable name (i.e., interpreter, such as bash) as well - assuming it is known; e.g.

# List instance(s) of a running *bash* script.
getbashscript() {
  pgrep -lf "(^|/)bash( | .*/)$1( |\$)"
}

If you're willing to make further assumptions - such as script-interpreter paths never containing embedded spaces - the regexes could be made more restrictive and thus further reduce the risk of false positives.

You can use

ng-bind-html https://docs.angularjs.org/api/ng/service/$sce

directive to bind html dynamically. However you have to get the data via $sce service.

Please see the live demo at http://plnkr.co/edit/k4s3Bx

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
    $scope.getHtml=function(){
   return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
   }
});

  <body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
  </body>

UPDLOCK is used when you want to lock a row or rows during a select statement for a future update statement. The future update might be the very next statement in the transaction.

Other sessions can still see the data. They just cannot obtain locks that are incompatiable with the UPDLOCK and/or HOLDLOCK.

You use UPDLOCK when you wan to keep other sessions from changing the rows you have locked. It restricts their ability to update or delete locked rows.

You use HOLDLOCK when you want to keep other sessions from changing any of the data you are looking at. It restricts their ability to insert, update, or delete the rows you have locked. This allows you to run the query again and see the same results.

Alternatively if you want to grab the private and public keys from a PuTTY formated key file you can use puttygen on *nix systems. For most apt-based systems puttygen is part of the putty-tools package.

Outputting a private key from a PuTTY formated keyfile:

$ puttygen keyfile.pem -O private-openssh -o avdev.pvk

For the public key:

$ puttygen keyfile.pem -L

After you clone repository repo, you can edit repo/.git/config and add some configuration like below:

[user]
    name = you_name
    password = you_password
[credential]
    helper = store

Then you won't be asked for username and password again.

I defined two functions in Site.Master:

    <script type="text/javascript">
    var spinnerVisible = false;
    function showProgress() {
        if (!spinnerVisible) {
            $("div#spinner").fadeIn("fast");
            spinnerVisible = true;
        }
    };
    function hideProgress() {
        if (spinnerVisible) {
            var spinner = $("div#spinner");
            spinner.stop();
            spinner.fadeOut("fast");
            spinnerVisible = false;
        }
    };
</script>

And special section:

    <div id="spinner">
        Loading...
    </div>

Visual style is defined in CSS:

div#spinner
{
    display: none;
    width:100px;
    height: 100px;
    position: fixed;
    top: 50%;
    left: 50%;
    background:url(spinner.gif) no-repeat center #fff;
    text-align:center;
    padding:10px;
    font:normal 16px Tahoma, Geneva, sans-serif;
    border:1px solid #666;
    margin-left: -50px;
    margin-top: -50px;
    z-index:2;
    overflow: auto;
}

I found this scriplet in a script that deletes all files older than 14 days:

CNT=0
for i in $(find -type f -ctime +14); do
  ((CNT = CNT + 1))
  echo -n "." >> $PROGRESS
  rm -f $i
done
echo deleted $CNT files, done at $(date "+%H:%M:%S") >> $LOG

I think a little additional "man find" and looking for the -ctime / -atime etc. parameters will help you here.

I tried using it and didn't work, guess it's just the modal versioin.

Although, it worked as this:

$("#myModal").on("hide.bs.modal", function () {
    // put your default event here
});

Just to update the answer =)

robotex tools which are free will let you do this but they make you enter the ip of the domain first:

1. find out the ip (there's a good ff plugin which does this but I can't post the link cos this is my first post here!)
2. do an ip search on robotex: http://www.robtex.com/ip/
3. in the results page that follows click on the domain you're interested in>
4. you are taken to a page that lists all subdomains + a load of other information such as mail server info

You should create a pseudo-random number generator only once:

Dim Generator As System.Random = New System.Random()

Then, if an integer suffices for your needs, you can use:

Public Function GetRandom(myGenerator As System.Random, ByVal Min As Integer, ByVal Max As Integer) As Integer
'min is inclusive, max is exclusive (dah!)
Return myGenerator.Next(Min, Max + 1)
End Function

as many times as you like. Using the wrapper function is justified only because the maximum value is exclusive - I know that the random numbers work this way but the definition of .Next is confusing.

Creating a generator every time you need a number is in my opinion wrong; the pseudo-random numbers do not work this way.

First, you get the problem with initialization which has been discussed in the other replies. If you initialize once, you do not have this problem.

Second, I am not at all certain that you get a valid sequence of random numbers; rather, you get a collection of the first number of multiple different sequences which are seeded automatically based on computer time. I am not certain that these numbers will pass the tests that confirm the randomness of the sequence.

Well, my answer is not just the summary of all the solutions, but it offers more than that.

Section (1):

In general solutions:

I had four errors of this kind (‘metadata file could not be found’) along with one error saying 'Source File Could Not Be Opened (‘Unspecified error ‘)'.

I tried to get rid of ‘metadata file could not be found’ error. For that, I read many posts, blogs, etc. and found these solutions may be effective (summarizing them over here):

1. Restart Visual Studio and try building again.

2. Go to 'Solution Explorer'. Right click on Solution. Go to Properties. Go to 'Configuration Manager'. Check if the checkboxes under 'Build' are checked or not. If any or all of them are unchecked, then check them and try building again.

3. If the above solution(s) do not work, then follow sequence mentioned in step 2 above, and even if all the checkboxes are checked, uncheck them, check again and try to build again.

4. Build Order and Project Dependencies:

   Go to 'Solution Explorer'. Right click on Solution. Go to 'Project Dependencies...'. You will see two tabs: 'Dependencies' and 'Build Order'. This build order is the one in which solution builds. Check the project dependencies and the build order to verify if some project (say 'project1') which is dependent on other (say 'project2') is trying to build before that one (project2). This might be the cause for the error.

5. Check the path of the missing .dll:

   Check the path of the missing .dll. If the path contains space or any other invalid path character, remove it and try building again.

   If this is the cause, then adjust the build order.

Section (2):

My particular case:

I tried all the steps above with various permutations and combinations with restarting Visual Studio a few times. But, it did not help me.

So, I decided to get rid of other error I was coming across ('Source File Could Not Be Opened (‘Unspecified error ‘)').

I came across a blog post: TFS Error–Source File Could Not Be Opened (‘Unspecified error ‘)

I tried the steps mentioned in that blog post, and I got rid of the error 'Source File Could Not Be Opened (‘Unspecified error ‘)' and surprisingly I got rid of other errors (‘metadata file could not be found’) as well.

Section (3):

Moral of the story:

Try all solutions as mentioned in section (1) above (and any other solutions) for getting rid of the error. If nothing works out, as per the blog mentioned in section (2) above, delete the entries of all source files which are no longer present in the source control and the file system from your .csproj file.

From Haskell:

Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry.

Basically Haskell can be used to create pretty much anything you would normally create using other general-purpose languages (e.g. C#, Java, C, C++, etc.).

A thorough explanation of the Singleton macro code is on the blog Cocoa With Love

Your friend here is org.springframework.web.context.request.RequestContextHolder

// example usage
public static HttpSession session() {
    ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
    return attr.getRequest().getSession(true); // true == allow create
}

This will be populated by the standard spring mvc dispatch servlet, but if you are using a different web framework you have add org.springframework.web.filter.RequestContextFilter as a filter in your web.xml to manage the holder.

EDIT: just as a side issue what are you actually trying to do, I'm not sure you should need access to the HttpSession in the retieveUser method of a UserDetailsService. Spring security will put the UserDetails object in the session for you any how. It can be retrieved by accessing the SecurityContextHolder:

public static UserDetails currentUserDetails(){
    SecurityContext securityContext = SecurityContextHolder.getContext();
    Authentication authentication = securityContext.getAuthentication();
    if (authentication != null) {
        Object principal = authentication.getPrincipal();
        return principal instanceof UserDetails ? (UserDetails) principal : null;
    }
    return null;
}

"title" is widely implemented in browsers. Try:

<a href="#" title="hello">asf</a>

If username or password has the @ character, then use it like this:

mongoose
    .connect(
        'DB_url',
        { user: '@dmin', pass: 'p@ssword', useNewUrlParser: true }
    )
    .then(() => console.log('Connected to MongoDB'))
    .catch(err => console.log('Could not connect to MongoDB', err));

An extremely important consideration in the choice of Expression vs Func is that IQueryable providers like LINQ to Entities can 'digest' what you pass in an Expression, but will ignore what you pass in a Func. I have two blog posts on the subject:

More on Expression vs Func with Entity Framework and Falling in Love with LINQ - Part 7: Expressions and Funcs (the last section)

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

For DictReader:

f = open(filename, "rb")
d = csv.DictReader(f, delimiter=",")

f.seek(0)
d.__init__(f, delimiter=",")

For DictWriter:

f = open(filename, "rb+")
d = csv.DictWriter(f, fieldnames=fields, delimiter=",")

f.seek(0)
f.truncate(0)
d.__init__(f, fieldnames=fields, delimiter=",")
d.writeheader()
f.flush()

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

Standard way:

@RestController
public class Main {
    UserService userService;

    public Main(){
        userService = new UserServiceImpl();
    }

    @GetMapping("/")
    public String index(){
        return userService.print("Example test");
    }
}

User service interface:

public interface UserService {
    String print(String text);
}

UserServiceImpl class:

public class UserServiceImpl implements UserService {
    @Override
    public String print(String text) {
        return text + " UserServiceImpl";
    }
}

Output: Example test UserServiceImpl

That is a great example of tight coupled classes, bad design example and there will be problem with testing (PowerMockito is also bad).

Now let's take a look at SpringBoot dependency injection, nice example of loose coupling:

Interface remains the same,

Main class:

@RestController
public class Main {
    UserService userService;

    @Autowired
    public Main(UserService userService){
        this.userService = userService;
    }

    @GetMapping("/")
    public String index(){
        return userService.print("Example test");
    }
}

ServiceUserImpl class:

@Component
public class UserServiceImpl implements UserService {
    @Override
    public String print(String text) {
        return text + " UserServiceImpl";
    }
}

Output: Example test UserServiceImpl

and now it's easy to write test:

@RunWith(MockitoJUnitRunner.class)
public class MainTest {
    @Mock
    UserService userService;

    @Test
    public void indexTest() {
        when(userService.print("Example test")).thenReturn("Example test UserServiceImpl");

        String result = new Main(userService).index();

        assertEquals(result, "Example test UserServiceImpl");
    }
}

I showed @Autowired annotation on constructor but it can also be used on setter or field.

If the service starts and stops like that, it means your code is throwing an unhandled exception. This is pretty difficult to debug, but there are a few options.

1. Consult the Windows Event Viewer. Normally you can get to this by going to the computer/server manager, then clicking Event Viewer -> Windows Logs -> Application. You can see what threw the exception here, which may help, but you don't get the stack trace.
2. Extract your program logic into a library class project. Now create two different versions of the program: a console app (for debugging), and the windows service. (This is a bit of initial effort, but saves a lot of angst in the long run.)
3. Add more try/catch blocks and logging to the app to get a better picture of what's going on.

I am writing tips and tricks only. It may be useful in tests and exams.

1. n = n*2: n = n<<1
2. n = n/2: n = n>>1
3. Checking if n is power of 2 (1,2,4,8,...): check !(n & (n-1))
4. Getting x^th bit of n: n |= (1 << x)
5. Checking if x is even or odd: x&1 == 0 (even)
6. Toggle the n^th bit of x: x ^ (1<<n)

Use the CSS overflow property:

.noscroll {
  width: 150px;
  height: 150px;
  overflow: auto; /* Or hidden, or visible */
}

Here are some more examples:

• overflow-x, overflow-y tests

netstat -ano|find ":port_no" will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .

example : netstat -ano | find ":1900" This gives you the result like this.

Swift 3 solution based on Ramis' answer:

extension String {
    func withReplacedCharacters(_ characters: String, by separator: String) -> String {
        let characterSet = CharacterSet(charactersIn: characters)
        return components(separatedBy: characterSet).joined(separator: separator)
    }
}

Tried to come up with an appropriate function name according to Swift 3 naming convention.

Using interface as message constant is generally a bad idea. It will leak into client program permanently as part of exported API. Who knows, that later client programmers might parse that error messages(public) as part of their program.

You will be locked forever to support this, as changes in string format will/may break client program.

Steps: 1. go to Run->Run configuration -> Maven Build -> New configuration
2. set base directory of you project ie.${workspace_loc:/shc-be-war}
3. set goal spring-boot:run
4. Run project from Run->New_Configuration

Lambda expressions are typically used to encapsulate algorithms so that they can be passed to another function. However, it is possible to execute a lambda immediately upon definition:

[&](){ ...your code... }(); // immediately executed lambda expression

is functionally equivalent to

{ ...your code... } // simple code block

This makes lambda expressions a powerful tool for refactoring complex functions. You start by wrapping a code section in a lambda function as shown above. The process of explicit parameterization can then be performed gradually with intermediate testing after each step. Once you have the code-block fully parameterized (as demonstrated by the removal of the &), you can move the code to an external location and make it a normal function.

Similarly, you can use lambda expressions to initialize variables based on the result of an algorithm...

int a = []( int b ){ int r=1; while (b>0) r*=b--; return r; }(5); // 5!

As a way of partitioning your program logic, you might even find it useful to pass a lambda expression as an argument to another lambda expression...

[&]( std::function<void()> algorithm ) // wrapper section
   {
   ...your wrapper code...
   algorithm();
   ...your wrapper code...
   }
([&]() // algorithm section
   {
   ...your algorithm code...
   });

Lambda expressions also let you create named nested functions, which can be a convenient way of avoiding duplicate logic. Using named lambdas also tends to be a little easier on the eyes (compared to anonymous inline lambdas) when passing a non-trivial function as a parameter to another function. Note: don't forget the semicolon after the closing curly brace.

auto algorithm = [&]( double x, double m, double b ) -> double
   {
   return m*x+b;
   };

int a=algorithm(1,2,3), b=algorithm(4,5,6);

If subsequent profiling reveals significant initialization overhead for the function object, you might choose to rewrite this as a normal function.

about Selenium IDE, I am not an expert but you have to add the line "choose ok on next confirmation" before the event which trigger the alert/confirm dialog box as you can see into this screenshot:

The input type="file" field is very tricky because it behaves differently on every browser, it can't be styled, or can be styled a little, depending on the browser again; and it is difficult to resize (depending on the browser again, it may have a minimal size that can't be overwritten).

There are workarounds though. The best one is in my opinion this one (the result is here).

The .push method can take multiple arguments. You can use the spread operator to pass all the elements of the second array as arguments to .push:

>>> a.push(...b)

If your browser does not support ECMAScript 6, you can use .apply instead:

>>> a.push.apply(a, b)

Or perhaps, if you think it's clearer:

>>> Array.prototype.push.apply(a,b)

Please note that all these solutions will fail with a stack overflow error if array b is too long (trouble starts at about 100,000 elements, depending on the browser).
If you cannot guarantee that b is short enough, you should use a standard loop-based technique described in the other answer.

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

If you are set on using EXISTS you can use the below in SQL Server:

SELECT * FROM TableB as b
WHERE NOT EXISTS
(
   SELECT * FROM TableA as a
   WHERE b.id = a.id
)

Valid longitudes are from -180 to 180 degrees.

Latitudes are supposed to be from -90 degrees to 90 degrees, but areas very near to the poles are not indexable.

So exact limits, as specified by EPSG:900913 / EPSG:3785 / OSGEO:41001 are the following:

• Valid longitudes are from -180 to 180 degrees.
• Valid latitudes are from -85.05112878 to 85.05112878 degrees.

In XSLT the same <xsl:variable> can be declared only once and can be given a value only at its declaration. If more than one variables are declared at the same time, they are in fact different variables and have different scope.

Therefore, the way to achieve the wanted conditional setting of the variable and producing its value is the following:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

    <xsl:template match="class">
    <xsl:variable name="subexists">
            <xsl:choose>
                <xsl:when test="joined-subclass">true</xsl:when>
                <xsl:otherwise>false</xsl:otherwise>
            </xsl:choose>
        </xsl:variable>
        subexists:  <xsl:text/>    
        <xsl:value-of select="$subexists" />
    </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on the following XML document:

<class>
 <joined-subclass/>
</class>

the wanted result is produced:

    subexists:  true

My situation was different I believe because non of the above solutions di work for me. Let me share my situation.

1. I am importing an existing project (NewProject->Java->Import Existing Projects)
2. I name the project to xyz. The 'main' function exists in Main.class.

3. I try to run the code I modified in the main function but the error pops out. I tried the shift_f6, specifically rebuild. Nothing works.

   Solution: I took the project properties and saw the 'Source Package Folder' mappings in the Sources branch was blank. I mapped it and voila it worked.

Now anyone might think that was very silly of me. Although I am new to Java and Netbeans this is not the first time I am importing sample projects and I saw all of them had the properties similar. The only difference I saw was that the main class was not having the name as the project which I believe is a java convention. I am using JDK7u51 (latest till date), is it causing the issue? I have no idea. But I am happy the project is running fine now.

In my case I imported maven project as Default existing project in eclipse.After that I imported as maven project.That worked for me.

Another option would be to set a flag variable as a Boolean and then change that value based on your criteria.

Dim count as Integer 
Dim flag as Boolean

flag = True

While flag
    count = count + 1 

    If count = 10 Then
        'Set the flag to false         '
        flag = false
    End If

The R Language Definition is handy for answering these types of questions:

• http://cran.r-project.org/doc/manuals/R-lang.html#Indexing

R has three basic indexing operators, with syntax displayed by the following examples

    x[i]
    x[i, j]
    x[[i]]
    x[[i, j]]
    x$a
    x$"a"

For vectors and matrices the [[ forms are rarely used, although they have some slight semantic differences from the [ form (e.g. it drops any names or dimnames attribute, and that partial matching is used for character indices). When indexing multi-dimensional structures with a single index, x[[i]] or x[i] will return the ith sequential element of x.

For lists, one generally uses [[ to select any single element, whereas [ returns a list of the selected elements.

The [[ form allows only a single element to be selected using integer or character indices, whereas [ allows indexing by vectors. Note though that for a list, the index can be a vector and each element of the vector is applied in turn to the list, the selected component, the selected component of that component, and so on. The result is still a single element.

An official example notebook demonstrating local file upload/download and integration with Drive and sheets is available here: https://colab.research.google.com/notebooks/io.ipynb

The simplest way to share files is to mount your Google Drive.

To do this, run the following in a code cell:

from google.colab import drive
drive.mount('/content/drive')

It will ask you to visit a link to ALLOW "Google Files Stream" to access your drive. After that a long alphanumeric auth code will be shown that needs to be entered in your Colab's notebook.

Afterward, your Drive files will be mounted and you can browse them with the file browser in the side panel.

Here's a full example notebook

Why not just fix the condition in your while loop, causing the problem to disappear?

while(msg->state != DONE)
{
    switch(msg->state) {
    case MSGTYPE: // ... 
        break;
    // ... more stuff ...
    case DONE:
        // We can't get here, but for completeness we list it.
        break; // **HERE, I want to break out of the loop itself**
    }
}

Sorting solutions have been proposed, but sorting is a little too much: We don't need order; we just need equality groups.

So hashing would be enough (and faster).

1. For each color of socks, form a pile. Iterate over all socks in your input basket and distribute them onto the color piles.
2. Iterate over each pile and distribute it by some other metric (e.g. pattern) into the second set of piles
3. Recursively apply this scheme until you have distributed all socks onto very small piles that you can visually process immediately

This kind of recursive hash partitioning is actually being done by SQL Server when it needs to hash join or hash aggregate over huge data sets. It distributes its build input stream into many partitions which are independent. This scheme scales to arbitrary amounts of data and multiple CPUs linearly.

You don't need recursive partitioning if you can find a distribution key (hash key) that provides enough buckets that each bucket is small enough to be processed very quickly. Unfortunately, I don't think socks have such a property.

If each sock had an integer called "PairID" one could easily distribute them into 10 buckets according to PairID % 10 (the last digit).

The best real-world partitioning I can think of is creating a rectangle of piles: one dimension is color, the other is the pattern. Why a rectangle? Because we need O(1) random-access to piles. (A 3D cuboid would also work, but that is not very practical.)

Update:

What about parallelism? Can multiple humans match the socks faster?

1. The simplest parallelization strategy is to have multiple workers take from the input basket and put the socks onto the piles. This only scales up so much - imagine 100 people fighting over 10 piles. The synchronization costs (manifesting themselves as hand-collisions and human communication) destroy efficiency and speed-up (see the Universal Scalability Law!). Is this prone to deadlocks? No, because each worker only needs to access one pile at a time. With just one "lock" there cannot be a deadlock. Livelocks might be possible depending on how the humans coordinate access to piles. They might just use random backoff like network cards do that on a physical level to determine what card can exclusively access the network wire. If it works for NICs, it should work for humans as well.
2. It scales nearly indefinitely if each worker has its own set of piles. Workers can then take big chunks of socks from the input basket (very little contention as they are doing it rarely) and they do not need to synchronise when distributing the socks at all (because they have thread-local piles). At the end, all workers need to union their pile-sets. I believe that can be done in O(log (worker count * piles per worker)) if the workers form an aggregation tree.

What about the element distinctness problem? As the article states, the element distinctness problem can be solved in O(N). This is the same for the socks problem (also O(N), if you need only one distribution step (I proposed multiple steps only because humans are bad at calculations - one step is enough if you distribute on md5(color, length, pattern, ...), i.e. a perfect hash of all attributes)).

Clearly, one cannot go faster than O(N), so we have reached the optimal lower bound.

Although the outputs are not exactly the same (in one case, just a boolean. In the other case, the pairs of socks), the asymptotic complexities are the same.

Strings aren't value types since they can be huge, and need to be stored on the heap. Value types are (in all implementations of the CLR as of yet) stored on the stack. Stack allocating strings would break all sorts of things: the stack is only 1MB for 32-bit and 4MB for 64-bit, you'd have to box each string, incurring a copy penalty, you couldn't intern strings, and memory usage would balloon, etc...

(Edit: Added clarification about value type storage being an implementation detail, which leads to this situation where we have a type with value sematics not inheriting from System.ValueType. Thanks Ben.)

The solution, based on this comment: https://stackoverflow.com/a/22409447/2399045 . Just set settings: DB name, temp folder, db files folder. And after run you will have the copy of DB with Name in "sourceDBName_yyyy-mm-dd" format.

-- Settings --
-- New DB name will have name = sourceDB_yyyy-mm-dd
declare @sourceDbName nvarchar(50) = 'MyDbName';
declare @tmpFolder nvarchar(50) = 'C:\Temp\'
declare @sqlServerDbFolder nvarchar(100) = 'C:\Databases\'

--  Execution --
declare @sourceDbFile nvarchar(50);
declare @sourceDbFileLog nvarchar(50);
declare @destinationDbName nvarchar(50) = @sourceDbName + '_' + (select convert(varchar(10),getdate(), 121))
declare @backupPath nvarchar(400) = @tmpFolder + @destinationDbName + '.bak'
declare @destMdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '.mdf'
declare @destLdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '_log' + '.ldf'

SET @sourceDbFile = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 0)

SET @sourceDbFileLog = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 1)

BACKUP DATABASE @sourceDbName TO DISK = @backupPath

RESTORE DATABASE @destinationDbName FROM DISK = @backupPath
WITH REPLACE,
   MOVE @sourceDbFile     TO @destMdf,
   MOVE @sourceDbFileLog  TO @destLdf

The main difference with shell config files is that some are only read by "login" shells (eg. when you login from another host, or login at the text console of a local unix machine). these are the ones called, say, .login or .profile or .zlogin (depending on which shell you're using).

Then you have config files that are read by "interactive" shells (as in, ones connected to a terminal (or pseudo-terminal in the case of, say, a terminal emulator running under a windowing system). these are the ones with names like .bashrc, .tcshrc, .zshrc, etc.

bash complicates this in that .bashrc is only read by a shell that's both interactive and non-login, so you'll find most people end up telling their .bash_profile to also read .bashrc with something like

[[ -r ~/.bashrc ]] && . ~/.bashrc

Other shells behave differently - eg with zsh, .zshrc is always read for an interactive shell, whether it's a login one or not.

The manual page for bash explains the circumstances under which each file is read. Yes, behaviour is generally consistent between machines.

.profile is simply the login script filename originally used by /bin/sh. bash, being generally backwards-compatible with /bin/sh, will read .profile if one exists.

Here is another version of weighted_choice that uses numpy. Pass in the weights vector and it will return an array of 0's containing a 1 indicating which bin was chosen. The code defaults to just making a single draw but you can pass in the number of draws to be made and the counts per bin drawn will be returned.

If the weights vector does not sum to 1, it will be normalized so that it does.

import numpy as np

def weighted_choice(weights, n=1):
    if np.sum(weights)!=1:
        weights = weights/np.sum(weights)

    draws = np.random.random_sample(size=n)

    weights = np.cumsum(weights)
    weights = np.insert(weights,0,0.0)

    counts = np.histogram(draws, bins=weights)
    return(counts[0])

if ([recognizer state] == UIGestureRecognizerStateChanged)

    img12.center=CGPointMake(img12.center.x+translation1.x, img12.center.y+ translation1.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:main_view];

    recognizer.view.center=CGPointMake(recognizer.view.center.x+translation1.x, recognizer.view.center.y+ translation1.y);
}

-(void)move:(UIPanGestureRecognizer*)recognizer
{
    if ([recognizer state] == UIGestureRecognizerStateChanged)    
    {

        recognizer.view.center=CGPointMake(recognizer.view.center.x+translation.x, recognizer.view.center.y+ translation.y);
        [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];
    }
}

height: 100% gives the element 100% height of its parent container.

height: auto means the element height will depend upon the height of its children.

Consider these examples:

height: 100%

<div style="height: 50px">
    <div id="innerDiv" style="height: 100%">
    </div>
</div>

#innerDiv is going to have height: 50px

height: auto

<div style="height: 50px">
    <div id="innerDiv" style="height: auto">
          <div id="evenInner" style="height: 10px">
          </div>
    </div>
</div>

#innerDiv is going to have height: 10px

In Spark < 1.6 If you create a HiveContext, not the plain old SqlContext you can use the HiveQL DISTRIBUTE BY colX... (ensures each of N reducers gets non-overlapping ranges of x) & CLUSTER BY colX... (shortcut for Distribute By and Sort By) for example;

df.registerTempTable("partitionMe")
hiveCtx.sql("select * from partitionMe DISTRIBUTE BY accountId SORT BY accountId, date")

Not sure how this fits in with Spark DF api. These keywords aren't supported in the normal SqlContext (note you dont need to have a hive meta store to use the HiveContext)

EDIT: Spark 1.6+ now has this in the native DataFrame API

string[] thisArray = myString.Split('/');//<string1/string2/string3/--->     
List<string> myList = new List<string>(); //make a new string list    
myList.AddRange(thisArray);    

Use AddRange to pass string[] and get a string list.

You can also use this variant with text strings, here's the complete changed code (Code from Mikael), tested in C# 2012:

// Variable
string MessageBoxTitle = "Some Title";
string MessageBoxContent = "Sure";

DialogResult dialogResult = MessageBox.Show(MessageBoxContent, MessageBoxTitle, MessageBoxButtons.YesNo);
if(dialogResult == DialogResult.Yes)
{
    //do something
}
else if (dialogResult == DialogResult.No)
{
    //do something else
}

You can after

.YesNo

insert a message icon

, MessageBoxIcon.Question

Enabeling GZip in Tomcat doesn't worked in my Spring Boot Project. I used CompressingFilter found here.

Indeed, you can use the "create" method of Mongoose, it can contain an array of documents, see this example:

Candy.create({ candy: 'jelly bean' }, { candy: 'snickers' }, function (err, jellybean, snickers) {
});

The callback function contains the inserted documents. You do not always know how many items has to be inserted (fixed argument length like above) so you can loop through them:

var insertedDocs = [];
for (var i=1; i<arguments.length; ++i) {
    insertedDocs.push(arguments[i]);
}

Update: A better solution

A better solution would to use Candy.collection.insert() instead of Candy.create() - used in the example above - because it's faster (create() is calling Model.save() on each item so it's slower).

See the Mongo documentation for more information: http://docs.mongodb.org/manual/reference/method/db.collection.insert/

(thanks to arcseldon for pointing this out)

Simple Way to add JTextArea in JScrollBar with JScrollPan

import javax.swing.*;

}

The real question is why does it generate a 500 error. If it is related to any input parameters, then I would argue that it should be handled internally and returned as a 400 series error. Generally a 400, 404 or 406 would be appropriate to reflect bad input since the general convention is that a RESTful resource is uniquely identified by the URL and a URL that cannot generate a valid response is a bad request (400) or similar.

If the error is caused by anything other than the inputs explicitly or implicitly supplied by the request, then I would say a 500 error is likely appropriate. So a failed database connection or other unpredictable error is accurately represented by a 500 series error.

'nunique' is an option for .agg() since pandas 0.20.0, so:

df.groupby('date').agg({'duration': 'sum', 'user_id': 'nunique'})

Javascript does not support two dimensional arrays, instead we store an array inside another array and fetch the data from that array depending on what position of that array you want to access. Remember array numeration starts at ZERO.

Code Example:

/* Two dimensional array that's 5 x 5 

       C0 C1 C2 C3 C4 
    R0[1][1][1][1][1] 
    R1[1][1][1][1][1] 
    R2[1][1][1][1][1] 
    R3[1][1][1][1][1] 
    R4[1][1][1][1][1] 
*/

var row0 = [1,1,1,1,1],
    row1 = [1,1,1,1,1],
    row2 = [1,1,1,1,1],
    row3 = [1,1,1,1,1],
    row4 = [1,1,1,1,1];

var table = [row0,row1,row2,row3,row4];
console.log(table[0][0]); // Get the first item in the array

None of these solutions worked for me on Windows 7 and within IDLE. Wound up using PowerShell, running Python within it and exiting to call "cls" in PowerShell to clear the window.

CONS: Assumes Python is already in the PATH variable. Also, this does clear your Python variables (though so does restarting the shell).

PROS: Retains any window customization you've made (color, font-size).

Here you can read more about different HTML parsers in Python and their performance. Even though the article is a bit dated it still gives you a good overview.

Python HTML parser performance

I'd recommend BeautifulSoup even though it isn't built in. Just because it's so easy to work with for those kinds of tasks. Eg:

import urllib2
from BeautifulSoup import BeautifulSoup

page = urllib2.urlopen('http://www.google.com/')
soup = BeautifulSoup(page)

x = soup.body.find('div', attrs={'class' : 'container'}).text

This did the trick for me: (solution from the msdn forum)

goto Controlpanel --> Administrative tools-->Component Services -->computers --> myComputer -->DCOM Config --> Microsoft Excel Application.

right click to get properties dialog. Goto Security tab and customize permissions accordingly.

In Launch and Application Permissions, select Customize, Edit. Add the user / group that calls the application.

pull = fetch + merge.

You need to commit what you have done before merging.

So pull after commit.

As noted in the comments, this only works AFTER you've DataBound your repeater.

To find a control in the header:

lblControl = repeater1.Controls[0].Controls[0].FindControl("lblControl");

To find a control in the footer:

lblControl = repeater1.Controls[repeater1.Controls.Count - 1].Controls[0].FindControl("lblControl");

With extension methods

public static class RepeaterExtensionMethods
{
    public static Control FindControlInHeader(this Repeater repeater, string controlName)
    {
        return repeater.Controls[0].Controls[0].FindControl(controlName);
    }

    public static Control FindControlInFooter(this Repeater repeater, string controlName)
    {
        return repeater.Controls[repeater.Controls.Count - 1].Controls[0].FindControl(controlName);
    }
}

You can encode your string by using .encode()

Example:

'Hello World'.encode()

What i came up with is :

1) Make a position:fixed <div> with width:100% (id=zoomdiv)

2) when the page loads :

zoomlevel=$("#zoomdiv").width()*1.0 / screen.availWidth

And it worked for me for ctrl+ and ctrl- zooms.

or i can add the line to a $(window).onresize() event to get the active zoom level

Code:

<script>
    var zoom=$("#zoomdiv").width()*1.0 / screen.availWidth;

    $(window).resize(function(){
        zoom=$("#zoomdiv").width()*1.0 / screen.availWidth;
        alert(zoom);    
    });
</script>
<body>
    <div id=zoomdiv style="width:100%;position:fixed;"></div>
</body>

P.S. : this is my first post, pardon any mistakes

 $.ajax({
            type: "POST",
            data: {data:the_id},
            url: "http://localhost/test/index.php/data/count_votes",
            success: function(data){
               //data will contain the vote count echoed by the controller i.e.  
                 "yourVoteCount"
              //then append the result where ever you want like
              $("span#votes_number").html(data); //data will be containing the vote count which you have echoed from the controller

                }
            });

in the controller

$data = $_POST['data'];  //$data will contain the_id
//do some processing
echo "yourVoteCount";

Clarification

i think you are confusing

{data:the_id}

with

success:function(data){

both the data are different for your own clarity sake you can modify it as

success:function(vote_count){
$(span#someId).html(vote_count);

df <- head(mtcars)
df$string <- c("a","b", "c", "d","e", "f"); df

my.min <- unlist(lapply(df, min))
my.max <- unlist(lapply(df, max))

I would consider to refactor the service to return your domain object rather than JSON strings and let Spring handle the serialization (via the MappingJacksonHttpMessageConverter as you write). As of Spring 3.1, the implementation looks quite neat:

@RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE, 
    method = RequestMethod.GET
    value = "/foo/bar")
@ResponseBody
public Bar fooBar(){
    return myService.getBar();
}

Comments:

First, the <mvc:annotation-driven /> or the @EnableWebMvc must be added to your application config.

Next, the produces attribute of the @RequestMapping annotation is used to specify the content type of the response. Consequently, it should be set to MediaType.APPLICATION_JSON_VALUE (or "application/json").

Lastly, Jackson must be added so that any serialization and de-serialization between Java and JSON will be handled automatically by Spring (the Jackson dependency is detected by Spring and the MappingJacksonHttpMessageConverter will be under the hood).

If you prefer to inform the visitor which links will be opened, you can use a JS function reading links from an html element. You can even let the visitor write/modify the links as seen below:

<script type="text/javascript"> 
    function open_all_links() {
        var x = document.getElementById('my_urls').value.split('\n');
        for (var i = 0; i < x.length; i++)
            if (x[i].indexOf('.') > 0)
            if (x[i].indexOf('://') < 0)
                window.open('http://' + x[i]);
            else
                window.open(x[i]);
    }
</script>



<form method="post" name="input" action=""> 
    <textarea id="my_urls" rows="4" placeholder="enter links in each row..."></textarea>
    <input value="open all now" type="button" onclick="open_all_links();">
</form>

I found new Solution without any required certification to call curl only add two line code.

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.
