Yet another version of the same kind of control. It has similar functionality as the others, but it adds:

1. Touch support (drag/pinch)
2. The image can be deleted (normally, the Image control locks the image on disk, so you cannot delete it).
3. An inner border child, so the panned image doesn't overlap the border. In case of borders with rounded rectangles, look for ClippedBorder classes.

Usage is simple:

<Controls:ImageViewControl ImagePath="{Binding ...}" />

And the code:

public class ImageViewControl : Border
{
    private Point origin;
    private Point start;
    private Image image;

    public ImageViewControl()
    {
        ClipToBounds = true;
        Loaded += OnLoaded;
    }

    #region ImagePath

        get { return (string) GetValue(ImagePathProperty); }
        set { SetValue(ImagePathProperty, value); }

        var newImagePath = target.ImagePath;
        target.ReloadImage(newImagePath);
        target.OnImagePathChanged(oldImagePath, newImagePath);
    }

See details in the below image. (VSCode version 1.19.1 - windows 10 OS)

It works on VS Code Mac as well. I tried it with VSCode (Version 1.20.1)

The easiest command line for this, which includes the PEM output to add it to the keystore, as well as a human readable output and also supports SNI, which is important if you are working with an HTTP server is:

openssl s_client -servername example.com -connect example.com:443 \
    </dev/null 2>/dev/null | openssl x509 -text

The -servername option is to enable SNI support and the openssl x509 -text prints the certificate in human readable format.

Here it is:

success: 
    function(data) {
        $.each(data, function(i, item){
            alert("Mine is " + i + "|" + item.title + "|" + item.key);
        });
    }

Sample JSON text:

{"title": "camp crowhouse", 
"key": "agtnZW90YWdkZXYyMXIKCxIEUG9zdBgUDA"}

I added Anaconda3/Library/Bin to the environment path and PyCharm no longer complained with the error.

Try this to your .htaccess file:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule >

Try

SELECT orgName, id, count(*) as dupes
FROM organizations
GROUP BY orgName, id
HAVING count(*) > 1;

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

What you have to do is something like this:

<Button Name="MyFlatImageButton"
        Background="Transparent"
        BorderBrush="Transparent"
        BorderThickness="0" 
        Padding="-4">
   <Image Source="MyImage.png"/>
</Button>

Hope this is what you were looking for.

Edit: Sorry, forgot to mention that if you want to see the button-border when you hover over the image, all you have to do is skip the Padding="-4".

$('select').change(function() {
    console.log($(this).val())
});?

jsFiddle example

.val() will get the value.

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

One solution to this would be a list comprehension, with pattern matching inside your tuple:

>>> mylist = [(25,7),(26,9),(55,10)]
>>> [age for (age,person_id) in mylist if person_id == 10]
[55]

Another way would be using map and filter:

>>> map( lambda (age,_): age, filter( lambda (_,person_id): person_id == 10, mylist) )
[55]

numbers = [1, 2, 3]
numsum = sum(list(numbers))
print(numsum)

This would work, if your are trying to Sum up a list.

The best thing that you can do is to set a function to be called on a given amount of time and this function to check the contents of your textarea.

self.setInterval('checkTextAreaValue()', 50);

I was asking the same to myself, and I found the answer in 1:

Take a look at section 8.1.7: the format "%z" (lowercase, the Z uppercase returns also the time zone, but not in the 4-digit format, but in the form of timezone abbreviations, like in [3]) of strftime returns the form "+/- 4DIGIT" that is standard in email headers (see section 3.3 of RFC 2822, see [2], which obsoletes the other ways of specifying the timezone for email headers).

So, if you want your timezone in this format, use:

time.strftime("%z")

[1] http://docs.python.org/2/library/datetime.html

[2] http://tools.ietf.org/html/rfc2822#section-3.3

[3] Timezone abbreviations: http://en.wikipedia.org/wiki/List_of_time_zone_abbreviations , only for reference.

ViewGroup is itself a View that works as a container for other views. It extends the functionality of View class in order to provide efficient ways to layout the child views.

For example, LinearLayout is a ViewGroup that lets you define the orientation in which you want child views to be laid, that's all you need to do and LinearLayout will take care of the rest.

You can use the syntax: $ENV{environment-variable} in your CMakeLists.txt to access environment variables. You could create scripts which initialize a set of environment variables appropriately and just have references to those variables in your CMakeLists.txt files.

You can use sort.Slice() plus sort.Search()

type Person struct {
    Name string
}

func main() {
    crowd := []Person{{"Zoey"}, {"Anna"}, {"Benni"}, {"Chris"}}

    sort.Slice(crowd, func(i, j int) bool {
        return crowd[i].Name <= crowd[j].Name
    })

    needle := "Benni"
    idx := sort.Search(len(crowd), func(i int) bool {
        return string(crowd[i].Name) >= needle
    })

    if crowd[idx].Name == needle {
        fmt.Println("Found:", idx, crowd[idx])
    } else {
        fmt.Println("Found noting: ", idx)
    }
}

In your AndroidManifest.xml file

<application
        android:name="ApplicationClass"
        android:icon="@drawable/ic_launcher"  <--------
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

Instead of using lu li, used dl (definition list) and dd. <dd> can be defined using standard css style such as {color:blue;font-size:1em;} and use as marker whatever symbol you place after the html tag. It works like ul li, but allows you to use any symbol, you just have to indent it to get the indented list effect you normally get with ul li.

CSS:
dd{text-indent:-10px;}

HTML
<dl>
<dd>- One</dd>
<dd>- Two</dd>
<dd>- Three</dd></dl>

Gives you much cleaner code! That way, you could use any type of character as marker! Indent is of about -10px and it works perfect!

The problem

C++ includes useful generic functions like std::for_each and std::transform, which can be very handy. Unfortunately they can also be quite cumbersome to use, particularly if the functor you would like to apply is unique to the particular function.

#include <algorithm>
#include <vector>

namespace {
  struct f {
    void operator()(int) {
      // do something
    }
  };
}

void func(std::vector<int>& v) {
  f f;
  std::for_each(v.begin(), v.end(), f);
}

If you only use f once and in that specific place it seems overkill to be writing a whole class just to do something trivial and one off.

In C++03 you might be tempted to write something like the following, to keep the functor local:

void func2(std::vector<int>& v) {
  struct {
    void operator()(int) {
       // do something
    }
  } f;
  std::for_each(v.begin(), v.end(), f);
}

however this is not allowed, f cannot be passed to a template function in C++03.

The new solution

C++11 introduces lambdas allow you to write an inline, anonymous functor to replace the struct f. For small simple examples this can be cleaner to read (it keeps everything in one place) and potentially simpler to maintain, for example in the simplest form:

void func3(std::vector<int>& v) {
  std::for_each(v.begin(), v.end(), [](int) { /* do something here*/ });
}

Lambda functions are just syntactic sugar for anonymous functors.

Return types

In simple cases the return type of the lambda is deduced for you, e.g.:

void func4(std::vector<double>& v) {
  std::transform(v.begin(), v.end(), v.begin(),
                 [](double d) { return d < 0.00001 ? 0 : d; }
                 );
}

however when you start to write more complex lambdas you will quickly encounter cases where the return type cannot be deduced by the compiler, e.g.:

void func4(std::vector<double>& v) {
    std::transform(v.begin(), v.end(), v.begin(),
        [](double d) {
            if (d < 0.0001) {
                return 0;
            } else {
                return d;
            }
        });
}

To resolve this you are allowed to explicitly specify a return type for a lambda function, using -> T:

void func4(std::vector<double>& v) {
    std::transform(v.begin(), v.end(), v.begin(),
        [](double d) -> double {
            if (d < 0.0001) {
                return 0;
            } else {
                return d;
            }
        });
}

"Capturing" variables

So far we've not used anything other than what was passed to the lambda within it, but we can also use other variables, within the lambda. If you want to access other variables you can use the capture clause (the [] of the expression), which has so far been unused in these examples, e.g.:

void func5(std::vector<double>& v, const double& epsilon) {
    std::transform(v.begin(), v.end(), v.begin(),
        [epsilon](double d) -> double {
            if (d < epsilon) {
                return 0;
            } else {
                return d;
            }
        });
}

You can capture by both reference and value, which you can specify using & and = respectively:

• [&epsilon] capture by reference
• [&] captures all variables used in the lambda by reference
• [=] captures all variables used in the lambda by value
• [&, epsilon] captures variables like with [&], but epsilon by value
• [=, &epsilon] captures variables like with [=], but epsilon by reference

The generated operator() is const by default, with the implication that captures will be const when you access them by default. This has the effect that each call with the same input would produce the same result, however you can mark the lambda as mutable to request that the operator() that is produced is not const.

Use encodeURI() in client JS and use URLDecoder.decode() in server Java side works.

Example:

• Javascript:

  $.getJSON(
      url,
      {
          "user": encodeURI(JSON.stringify(user))
      },
      onSuccess
  );
  

• Java:

  java.net.URLDecoder.decode(params.user, "UTF-8");

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

If you don't know which checkboxes your page has (ex: if you are creating them dynamically) you can simply put a hidden field with the same name and 0 value right above the checkbox.

<input type="hidden" name="foo" value="0" />
<input type="checkbox" name="foo" value="1">

This way you will get 1 or 0 based on whether the checkbox is selected or not.

As an addition to other answers, unix considers everything as a file system. Your keyboard is a file that is read only from the perspective of the kernel. The screen is a write only file. Similarly, folders, input-output devices etc are also considered to be files. Whenever a file is opened, say when the device drivers[for device files] requests an open(), or a process opens an user file the kernel allocates a file descriptor, an integer that specifies the access to that file such it being read only, write only etc. [for reference : https://en.wikipedia.org/wiki/Everything_is_a_file ]

You can use sklearn.preprocessing:

from sklearn.preprocessing import normalize
data = np.array([
    [1000, 10, 0.5],
    [765, 5, 0.35],
    [800, 7, 0.09], ])
data = normalize(data, axis=0, norm='max')
print(data)
>>[[ 1.     1.     1.   ]
[ 0.765  0.5    0.7  ]
[ 0.8    0.7    0.18 ]]

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

I know this has already been answered... but I wanted to give a more complete example.

In my example, the ListActivity that will display our custom ListView is called OptionsActivity, because in my project this Activity is going to display the different options my user can set to control my app. There are two list item types, one list item type just has a TextView and the second list item type just has a Button. You can put any widgets you like inside each list item type, but I kept this example simple.

The getItemView() method checks to see which list items should be type 1 or type 2. According to my static ints I defined up top, the first 5 list items will be list item type 1, and the last 5 list items will be list item type 2. So if you compile and run this, you will have a ListView that has five items that just contain a Button, and then five items that just contain a TextView.

Below is the Activity code, the activity xml file, and an xml file for each list item type.

OptionsActivity.java:

public class OptionsActivity extends ListActivity {

    private static final int LIST_ITEM_TYPE_1 = 0;
    private static final int LIST_ITEM_TYPE_2 = 1;
    private static final int LIST_ITEM_TYPE_COUNT = 2;

    private static final int LIST_ITEM_COUNT = 10;
    // The first five list items will be list item type 1 
    // and the last five will be list item type 2
    private static final int LIST_ITEM_TYPE_1_COUNT = 5;

    private MyCustomAdapter mAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mAdapter = new MyCustomAdapter();
        for (int i = 0; i < LIST_ITEM_COUNT; i++) {
          if (i < LIST_ITEM_TYPE_1_COUNT)
            mAdapter.addItem("item type 1");
          else
            mAdapter.addItem("item type 2");
        }
        setListAdapter(mAdapter);
    }

    private class MyCustomAdapter extends BaseAdapter {

        private ArrayList<String> mData = new ArrayList<String>();
        private LayoutInflater mInflater;

        public MyCustomAdapter() {
            mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

            mData.add(item);
            notifyDataSetChanged();
        }

          if(position < LIST_ITEM_TYPE_1_COUNT)
              return LIST_ITEM_TYPE_1;
          else
              return LIST_ITEM_TYPE_2;
        }

        @Override

            ViewHolder holder = null;
            int type = getItemViewType(position);
            if (convertView == null) {
                holder = new ViewHolder();
                switch(type) {
                    case LIST_ITEM_TYPE_1:
                        convertView = mInflater.inflate(R.layout.list_item_type1, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type1_text_view);
                        break;
                    case LIST_ITEM_TYPE_2:
                        convertView = mInflater.inflate(R.layout.list_item_type2, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type2_button);
                        break;
                }
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder)convertView.getTag();
            }
            holder.textView.setText(mData.get(position));

For me issue is resolved by changing envs like this:

 env.put("LDAP_BASEDN", base)
 env.put(Context.SECURITY_PRINCIPAL,"user@domain")

Also, you can display current position by "drag" listener and write it to visible or hidden field. You may also need to store zoom. Here's copy&paste from working tool:

            function map_init() {
            var lt=48.451778;
            var lg=31.646305;

            var myLatlng = new google.maps.LatLng(lt,lg);
            var mapOptions = {
                center: new google.maps.LatLng(lt,lg),
                zoom: 6,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };

            var map = new google.maps.Map(document.getElementById('map'),mapOptions);   
            var marker = new google.maps.Marker({
                position:myLatlng,
                map:map,
                draggable:true
            });

            google.maps.event.addListener(
                marker,
                'drag',
                function() {
                    document.getElementById('lat1').innerHTML = marker.position.lat().toFixed(6);
                    document.getElementById('lng1').innerHTML = marker.position.lng().toFixed(6);
                    document.getElementById('zoom').innerHTML = mapObject.getZoom();

                    // Dynamically show it somewhere if needed
                    $(".x").text(marker.position.lat().toFixed(6));
                    $(".y").text(marker.position.lng().toFixed(6));
                    $(".z").text(map.getZoom());

                }
            );                  
            }

You haven't specified what kind of html element you are trying to do an absolute xpath search on. In your case, it's the input element.

Try this:

element = findElement(By.xpath("//input[@class='t-TextBox' and @type='email' and @test-    
id='test-username']");

This Blog article explains the internals of ODEX files:

WHAT IS AN ODEX FILE?

In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.

You can try this .... you can play with the values. The shadowRadius dictates the amount of blur. shadowOffset dictates where the shadow goes.

Swift 2.0

let radius: CGFloat = demoView.frame.width / 2.0 //change it to .height if you need spread for height
let shadowPath = UIBezierPath(rect: CGRect(x: 0, y: 0, width: 2.1 * radius, height: demoView.frame.height))
//Change 2.1 to amount of spread you need and for height replace the code for height

demoView.layer.cornerRadius = 2
demoView.layer.shadowColor = UIColor.blackColor().CGColor
demoView.layer.shadowOffset = CGSize(width: 0.5, height: 0.4)  //Here you control x and y
demoView.layer.shadowOpacity = 0.5
demoView.layer.shadowRadius = 5.0 //Here your control your blur
demoView.layer.masksToBounds =  false
demoView.layer.shadowPath = shadowPath.CGPath

Swift 3.0

let radius: CGFloat = demoView.frame.width / 2.0 //change it to .height if you need spread for height 
let shadowPath = UIBezierPath(rect: CGRect(x: 0, y: 0, width: 2.1 * radius, height: demoView.frame.height)) 
//Change 2.1 to amount of spread you need and for height replace the code for height

demoView.layer.cornerRadius = 2
demoView.layer.shadowColor = UIColor.black.cgColor
demoView.layer.shadowOffset = CGSize(width: 0.5, height: 0.4)  //Here you control x and y
demoView.layer.shadowOpacity = 0.5
demoView.layer.shadowRadius = 5.0 //Here your control your blur
demoView.layer.masksToBounds =  false
demoView.layer.shadowPath = shadowPath.cgPath

Example with spread

To create a basic shadow

    demoView.layer.cornerRadius = 2
    demoView.layer.shadowColor = UIColor.blackColor().CGColor
    demoView.layer.shadowOffset = CGSizeMake(0.5, 4.0); //Here your control your spread
    demoView.layer.shadowOpacity = 0.5 
    demoView.layer.shadowRadius = 5.0 //Here your control your blur

Basic Shadow example in Swift 2.0

When a and b are 1-dimensional sequences, numpy.cov(a,b)[0][1] is equivalent to your cov(a,b).

The 2x2 array returned by np.cov(a,b) has elements equal to

cov(a,a)  cov(a,b)

cov(a,b)  cov(b,b)

(where, again, cov is the function you defined above.)

This works for me in Outlook:

<img src="image.jpg" width="120" style="display:block;width:100%" />

I hope it works for you.

The C99 way is

#include <inttypes.h>
int64_t my_int = 999999999999999999;
printf("%" PRId64 "\n", my_int);

Or you could cast!

printf("%ld", (long)my_int);
printf("%lld", (long long)my_int); /* C89 didn't define `long long` */
printf("%f", (double)my_int);

If you're stuck with a C89 implementation (notably Visual Studio) you can perhaps use an open source <inttypes.h> (and <stdint.h>): http://code.google.com/p/msinttypes/

the below lines would also work

!python script.py

lace to store your loaded class definition and metadata. If a large code-base project is loaded, the insufficient Perm Gen size will cause the popular Java.Lang.OutOfMemoryError: PermGen.

x_train = x_train.reshape(-1,28, 28, 1)   #Reshape for CNN -  should work!!
x_test = x_test.reshape(-1,28, 28, 1)
history_cnn = cnn.fit(x_train, y_train, epochs=5, validation_data=(x_test, y_test))

You can't use variable names to bind columns or other system objects, you need dynamic sql

DECLARE @value varchar(10)  
SET @value = 'intStep'  
DECLARE @sqlText nvarchar(1000); 

SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)

A lot of this has to do with polymorphism. When you assign

X = new Y();

X can be much less 'specific' than Y, but not the other way around. X is just the handle you are accessing Y with, Y is the real instantiated thing,

You get an error here because Integer is a Number, but Number is not an Integer.

ArrayList<Integer> a = new ArrayList<Number>(); // compile-time error

As such, any method of X that you call must be valid for Y. Since X is more generally it probably shares some, but not all of Y's methods. Still, any arguments given must be valid for Y.

In your examples with add, an int (small i) is not a valid Object or Integer.

ArrayList<?> a = new ArrayList<?>();

This is no good because you can't actually instantiate an array list containing ?'s. You can declare one as such, and then damn near anything can follow in new ArrayList<Whatever>();

If l is your list and X is your value:

for i in range(len(l) + 1):
    print l[:i] + [X] + l[i:]

I had the same problem and performed all updates from the first post. But after checking the log file,

/usr/local/var/postgres/server.log

I see the true cause:

FATAL:  data directory "/usr/local/var/postgres" has group or world access
DETAIL:  Permissions should be u=rwx (0700).

After changing permissions on this directory,

chmod 0700 /usr/local/var/postgres

the PostgreSQL server started.

Check the log file every time.

And in addition to the above nice answers.

• DSA uses Discrete logarithm.
• RSA uses Integer Factorization.

RSA stands for Ron Rivest, Adi Shamir and Leonard Adleman.

rand(6)    #=> gives a random number between 0 and 6 inclusively 
rand(1..6) #=> gives a random number between 1 and 6 inclusively

Note that the range option is only available in newer(1.9+ I believe) versions of ruby.

There are multiple function to do this work that wrote in bottom based on priority.

• .css()

Set one or more CSS properties for the set of matched elements.

$("div").css("display", "block")

// Or add multiple CSS properties
$("div").css({
  display: "block",
  color: "red",
  ...
})

• .show()

Display the matched elements and is roughly equivalent to calling .css("display", "block")

You can display element using .show() instead

$("div").show()

• .attr()

Set one or more attributes for the set of matched elements.

If target element hasn't style attribute, you can use this method to add inline style to element.

$("div").attr("style", "display:block")

// Or add multiple CSS properties
$("div").attr("style", "display:block; color:red")

• JavaScript

You can add specific CSS property to element using pure javascript, if you don't want to use jQuery.

var div = document.querySelector("div");
// One property
div.style.display = "block";
// Multiple properties
div.style.cssText = "display:block; color:red"; 
// Multiple properties
div.setAttribute("style", "display:block; color:red");

To get the execution time as a variable in your proc:

DECLARE @EndTime datetime
DECLARE @StartTime datetime 
SELECT @StartTime=GETDATE() 

-- Write Your Query


SELECT @EndTime=GETDATE()

--This will return execution time of your query
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in millisecs] 

AND see this

Don't just link to the line numbers! Be sure to use the canonical URL too. Otherwise when that file is updated, you'll have a URL that points to the wrong lines!

How to make a permanent link to the right lines:

Click on the line number you want (like line 18), and the URL in your browser will get a #L18 tacked onto the end. You literally click on the 18 at the left side, not the line of code. Looks like this:

And now your browser's URL looks like this:

https://github.com/git/git/blob/master/README#L18

If you want multiple lines selected, simply hold down the shift key and click a second line number, like line 20. Looks like this:

And now your browser's URL looks like this:

https://github.com/git/git/blob/master/README#L18-L20

Here's the important part:

Now get the canonical url for that particular commit by pressing the y key. The URL in your browser will change to become something like this:

https://github.com/git/git/blob/5bdb7a78adf2a2656a1915e6fa656aecb45c1fc3/README#L18-L20

That link contains the actual SHA hash for that particular commit, rather than the current version of the file on master. That means that this link will work forever and not point to lines 18-20 of whatever future version of that file might contain.

Now bask in the glow of your new permanent link. ;-)

update 9/29/2017: As pointed out by @watashiSHUN, github has now made it easier to get the permanent link by providing a ... menu on the left after you select one or more lines. Please upvote @watashiSHUN's answer too.

update 3/25/2016: Case in point — in the example above, I referred to the "README" file in the URL. Those non-canonical urls actually worked when this answer was written. But now those urls no longer work since README was moved to README.md. But the canonical URL with SHA hash still works, just as expected.

As an alternative to @Eric Lease's decorator, which unfortunately doesn't work using --aot (and thus --prod) builds, I resorted to using a service which exposes all my application's enums. Just need to publicly inject that into each component which requires it, under an easy name, after which you can access the enums in your views. E.g.:

Service

import { Injectable } from '@angular/core';
import { MyEnumType } from './app.enums';

@Injectable()
export class EnumsService {
  MyEnumType = MyEnumType;
  // ...
}

Don't forget to include it in your module's provider list.

Component class

export class MyComponent {
  constructor(public enums: EnumsService) {}
  @Input() public someProperty: MyEnumType;

  // ...
}

Component html

<div *ngIf="someProperty === enums.MyEnumType.SomeValue">Match!</div>

This line:

private dynamic defaultReminder = 
                          reminder.TimeSpanText[TimeSpan.FromMinutes(15)];

You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder will be initialized before defaultReminder, so the above line might throw a NullReferenceException.

Instead, just use:

private dynamic defaultReminder = TimeSpan.FromMinutes(15);

Alternatively, set up the value in the constructor:

private dynamic defaultReminder;

public Reminders()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 
}

There are more details about this compiler error on MSDN - Compiler Error CS0236.

Sometimes you need to reset ADB. To do that, in Eclipse, go:

Window>> Show View >> Android (Might be found in the "Other" option)>>Devices

in the device Tab, click the down arrow, and choose reset adb.

You can also use the AbsorbPointer, and you can use it in the following way:

AbsorbPointer(
      absorbing: true, // by default is true
      child: RaisedButton(
        onPressed: (){
          print('pending to implement onPressed function');
        },
        child: Text("Button Click!!!"),
      ),
    ),

Here is the answer for those of you who need a Boostrap 3 solution.

In bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line

// tab
$('#rowTab a:first').tab('show');

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//show selected tab / active
 console.log ( $(e.target).attr('id') );
});

It seems to be a known issue. You can instruct m2e to ignore this.

Option 1: pom.xml

Add the following inside your <build/> tag:

<pluginManagement>

Option 2: Global Eclipse Override

To avoid changing your POM files, the ignore override can be applied to the whole workspace via Eclipse settings.

Save this file somewhere on the disk: https://gist.github.com/maksimov/8906462

In Eclipse/Preferences/Maven/Lifecycle Mappings browse to this file and click OK:

If it is on a Linux box, I would suggest you add the database IP name and IP resolution to the /etc/hosts.

I have the same error and when we do the above, it works fine.

short answer you have to mix between them , use json for data that you are not going to make relations with them like contact data , address , products variabls

There's a lot of similar responses to this question, but none of them fully touch on the root cause. Sebastian Schmid's comment on the original post touches on it but not fully. Here's my take as of 2018-11-06:

Root Cause

When you try to upload a plugin through the WordPress admin interface, WordPress will make a call over to a function called "get_filesystem_method()" (ref: /wp-admin/includes/file.php:1549). This routine will attempt to write a file to the location in question (in this case the plugin directory). It can of course fail here immediately if file permissions aren't setup right to allow the WordPress user (think the user identity executing the php) to write the file to the location in question.

If the file can be created, this function then detects the file owner of the temporary file, along with the file owner of the function's current file (ref: /wp-admin/includes/file.php:1572) and compares the two. If they match then, in WordPress's words, "WordPress is creating files as the same owner as the WordPress files, this means it's safe to modify & create new files via PHP" and your plugin is uploaded successfully without the FTP Credentials prompt. If they don't match, you get the FTP Credentials prompt.

Fixes

1. Ensure the plugin directory is writable by the identity running your php process.

2. Ensure the identity that is running your php process is the file owner for either:

   a) All WordPress application files, or...
   b) At the very least the /wp-admin/includes/file.php file

Final Comments

I'm not overly keen on specifically applying file ownership to the file.php to work around this issue (it feels a tad hacky to say the least!). It seems to me at this point that the WordPress code base is leaning towards having us execute the PHP process under the same user principal as the file owner for the WordPress application files. I would welcome some comments from the community on this.

For PHP >= 5.4 use

$var = []; 

Not sure if it's faster than

$var = array();

but at least looks cleaner.

An ImageView gets setLayoutParams from View which uses ViewGroup.LayoutParams. If you use that, it will crash in most cases so you should use getLayoutParams() which is in View.class. This will inherit the parent View of the ImageView and will work always. You can confirm this here: ImageView extends view

Assuming you have an ImageView defined as 'image_view' and the width/height int defined as 'thumb_size'

The best way to do this:

ViewGroup.LayoutParams iv_params_b = image_view.getLayoutParams();
iv_params_b.height = thumb_size;
iv_params_b.width = thumb_size;
image_view.setLayoutParams(iv_params_b);

The regular expression you are after will most likely be huge and a nightmare to maintain especially for people who are not that familiar with regular expressions.

I think it would be easier to break your regex down and do it one bit at a time. It might take a bit more to do, but I am pretty sure that maintaining it and debugging it would be easier. This would also allow you to provide more directed error messages to your users (other than just Invalid Password) which should improve user experience.

From what I am seeing you are pretty fluent in regex, so I would presume that giving you the regular expressions to do what you need would be futile.

Seeing your comment, this is how I would go about it:

• Must be eight characters Long: You do not need a regex for this. Using the .Length property should be enough.

• Including one uppercase letter: You can use the [A-Z]+ regular expression. If the string contains at least one upper case letter, this regular expression will yield true.

• One special character: You can use either the \W which will match any character which is not a letter or a number or else, you can use something like so [!@#] to specify a custom list of special characters. Note though that characters such as $, ^, ( and ) are special characters in the regular expression language, so they need to be escaped like so: \$. So in short, you might use the \W.

• Alphanumeric characters: Using the \w+ should match any letter and number and underscore.

Take a look at this tutorial for more information.

To get an access token: facebook Graph API Explorer

You can customize specific access permissions, basic permissions are included by default.

If you declare the variable "annualRate" like

class Program {

**static double annualRate;**

public static void Main() {

Try it..

Here is my regular expression, that I used for removing all the special characters from any string :

String regex = ("[ \\\\s@  [\\\"]\\\\[\\\\]\\\\\\\0-9|^{#%'*/<()>}:`;,!& .?_$+-]+")

I think killing the process which is uses that port is more easy to handle than changing the ports in config files. Here is how to do it in Windows. You can follow same procedure to Linux but different commands. Run command prompt as Administrator. Then type below command to find out all of processes using the port.

netstat -ano

There will be plenty of processes using various ports. So to get only port we need use findstr like below (here I use port 80)

netstat -ano | findstr 80

this will gave you result like this

TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       7964

Last number is the process ID of the process. so what we have to do is kill the process using PID we can use taskkill command for that.

taskkill /PID 7964 /F

Run your server again. This time it will be able to run. This can uses for Mysql server too.

I think your solution is one of the shorter ones I've seen for this. I don't think there are any standard JavaScript functions to do this sort of thing, so you're probably on your own.

I checked the CSS 3 specifications to see whether it's possible to do this in CSS, but unless you want every digit in its own <span>, I don't think that's possible.

I did find one project on Google Code that looked promising: flexible-js-formatting. I haven't used it, but it looks pretty flexible and has unit tests using JsUnit. The developer also has a lot of posts (though old) about this topic.

Be sure to consider international users: lots of nations use a space as the separator and use the comma for separating the decimal from the integral part of the number.

I have been playing with this as well.

1. goto your elastic beanstalk service tab
2. on your application overview goto action --> edit configuration
3. add the name of a key as it appears in your EC2 tab (for the same region) to the existing keypair box and hit apply changes

The service will be relaunched so make a coffee for 5 mins

On your ec2 tab for the same region you'll see your new running instance. ssh to the public dns name as ec2-user using the key added in 3 e.g. ssh [email protected]

With Visual Studio 1.43 (Q1 2020), the Ctrl+K then O keyboard shortcut will work for a file.

See issue 89989:

It should be possible to e.g. invoke the "Open Active File in New Window" command and open that file into an empty workspace in the web.

props.children represents the content between the opening and the closing tags when invoking/rendering a component:

const Foo = props => (
  <div>
    <p>I'm {Foo.name}</p>
    <p>abc is: {props.abc}</p>

    <p>I have {props.children.length} children.</p>
    <p>They are: {props.children}.</p>
    <p>{Array.isArray(props.children) ? 'My kids are an array.' : ''}</p>
  </div>
);

const Baz = () => <span>{Baz.name} and</span>;
const Bar = () => <span> {Bar.name}</span>;

invoke/call/render Foo:

<Foo abc={123}>
  <Baz />
  <Bar />
</Foo>

The simplest way I found is:

$date   = new DateTime(); //this returns the current date time
$result = $date->format('Y-m-d-H-i-s');
echo $result . "<br>";
$krr    = explode('-', $result);
$result = implode("", $krr);
echo $result;

I hope it helps.

Typescript

public blobToFile = (theBlob: Blob, fileName:string): File => {       
    return new File([theBlob], fileName, { lastModified: new Date().getTime(), type: theBlob.type })
}

Javascript

function blobToFile(theBlob, fileName){       
    return new File([theBlob], fileName, { lastModified: new Date().getTime(), type: theBlob.type })
}

Output

Use defaultValue to select the default value.

    const statusOptions = [
        { value: 1, label: 'Publish' },
        { value: 0, label: 'Unpublish' }
    ];
    const [statusValue, setStatusValue] = useState('');
    const handleStatusChange = e => {
        setStatusValue(e.value);
    }

return(
<>

    onChange={handleStatusChange} 
    value={statusOptions.find(obj => obj.value === statusValue)} required />

What we usually do with e-mail, preventing spam-folders as the end destination, is using either Gmail as the smtp server or Mandrill as the smtp server.

Store it anywhere in an accessible location except of the IDE's project folder aka the server's deploy folder, for reasons mentioned in the answer to Uploaded image only available after refreshing the page:

1. Changes in the IDE's project folder does not immediately get reflected in the server's work folder. There's kind of a background job in the IDE which takes care that the server's work folder get synced with last updates (this is in IDE terms called "publishing"). This is the main cause of the problem you're seeing.

2. In real world code there are circumstances where storing uploaded files in the webapp's deploy folder will not work at all. Some servers do (either by default or by configuration) not expand the deployed WAR file into the local disk file system, but instead fully in the memory. You can't create new files in the memory without basically editing the deployed WAR file and redeploying it.

3. Even when the server expands the deployed WAR file into the local disk file system, all newly created files will get lost on a redeploy or even a simple restart, simply because those new files are not part of the original WAR file.

It really doesn't matter to me or anyone else where exactly on the local disk file system it will be saved, as long as you do not ever use getRealPath() method. Using that method is in any case alarming.

The path to the storage location can in turn be definied in many ways. You have to do it all by yourself. Perhaps this is where your confusion is caused because you somehow expected that the server does that all automagically. Please note that @MultipartConfig(location) does not specify the final upload destination, but the temporary storage location for the case file size exceeds memory storage threshold.

So, the path to the final storage location can be definied in either of the following ways:

• Hardcoded:

    File uploads = new File("/path/to/uploads");
  

• Environment variable via SET UPLOAD_LOCATION=/path/to/uploads:

    File uploads = new File(System.getenv("UPLOAD_LOCATION"));
  

• VM argument during server startup via -Dupload.location="/path/to/uploads":

    File uploads = new File(System.getProperty("upload.location"));
  

• *.properties file entry as upload.location=/path/to/uploads:

    File uploads = new File(properties.getProperty("upload.location"));
  

• web.xml <context-param> with name upload.location and value /path/to/uploads:

    File uploads = new File(getServletContext().getInitParameter("upload.location"));
  

• If any, use the server-provided location, e.g. in JBoss AS/WildFly:

    File uploads = new File(System.getProperty("jboss.server.data.dir"), "uploads");
  

Either way, you can easily reference and save the file as follows:

File file = new File(uploads, "somefilename.ext");

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath());
}

Or, when you want to autogenerate an unique file name to prevent users from overwriting existing files with coincidentally the same name:

File file = File.createTempFile("somefilename-", ".ext", uploads);

try (InputStream input = part.getInputStream()) {
    Files.copy(input, file.toPath(), StandardCopyOption.REPLACE_EXISTING);
}

Note: do not use Part#write() as it interprets the path relative to the temporary storage location defined in @MultipartConfig(location).

It depends on what you need to do. You can use replace since you want to replace the value:

select replace(email, '.com', '.org')
from yourtable

Then to UPDATE your table with the new ending, then you would use:

update yourtable
set email = replace(email, '.com', '.org')

You can also expand on this by checking the last 4 characters of the email value:

update yourtable
set email = replace(email, '.com', '.org')
where right(email, 4) = '.com'

However, the issue with replace() is that .com can be will in other locations in the email not just the last one. So you might want to use substring() the following way:

update yourtable
set email = substring(email, 1, len(email) -4)+'.org'
where right(email, 4) = '.com';

See SQL Fiddle with Demo

Using substring() will return the start of the email value, without the final .com and then you concatenate the .org to the end. This prevents the replacement of .com elsewhere in the string.

Alternatively you could use stuff(), which allows you to do both deleting and inserting at the same time:

update yourtable
set email = stuff(email, len(email) - 3, 4, '.org')
where right(email, 4) = '.com';

This will delete 4 characters at the position of the third character before the last one (which is the starting position of the final .com) and insert .org instead.

See SQL Fiddle with Demo for this method as well.

WOW, I gotta say: keep it simple:

MessageBox.Show("Result: " + (DateTime.Now.AddDays(10) > DateTime.Now));

Result: True

and:

MessageBox.Show("Result: " + DateTime.Now.AddDays(10).Subtract(DateTime.Now));

Result: 10.00:00:00

The DateTime object has all the builtin logic to handle the Boolean result.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

To check OleDbConnection State use this:

if (oconn.State == ConnectionState.Open)
{
    oconn.Close();
}

State return the ConnectionState

public override ConnectionState State { get; }

Here are the other ConnectionState enum

public enum ConnectionState
    {
        //
        // Summary:
        //     The connection is closed.
        Closed = 0,
        //
        // Summary:
        //     The connection is open.
        Open = 1,
        //
        // Summary:
        //     The connection object is connecting to the data source. (This value is reserved
        //     for future versions of the product.)
        Connecting = 2,
        //
        // Summary:
        //     The connection object is executing a command. (This value is reserved for future
        //     versions of the product.)
        Executing = 4,
        //
        // Summary:
        //     The connection object is retrieving data. (This value is reserved for future
        //     versions of the product.)
        Fetching = 8,
        //
        // Summary:
        //     The connection to the data source is broken. This can occur only after the connection
        //     has been opened. A connection in this state may be closed and then re-opened.
        //     (This value is reserved for future versions of the product.)
        Broken = 16
    }

$ git submodule status --recursive

Is also a life saver in this situation. You can use it and gitk --all to keep track of your sha1's and verify your sub-modules are pointing at what you think they are.

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

1) I am sure there is no difference speedwise, both use FileInputStream internally and buffering

2) You can take measurements and see for yourself

3) Though there's no performance benefits I like the 1.7 approach

try (BufferedReader br = Files.newBufferedReader(Paths.get("test.txt"), StandardCharsets.UTF_8)) {
    for (String line = null; (line = br.readLine()) != null;) {
        //
    }
}

4) Scanner based version

    try (Scanner sc = new Scanner(new File("test.txt"), "UTF-8")) {
        while (sc.hasNextLine()) {
            String line = sc.nextLine();
        }
        // note that Scanner suppresses exceptions
        if (sc.ioException() != null) {
            throw sc.ioException();
        }
    }

5) This may be faster than the rest

try (SeekableByteChannel ch = Files.newByteChannel(Paths.get("test.txt"))) {
    ByteBuffer bb = ByteBuffer.allocateDirect(1000);
    for(;;) {
        StringBuilder line = new StringBuilder();
        int n = ch.read(bb);
        // add chars to line
        // ...
    }
}

it requires a bit of coding but it can be really faster because of ByteBuffer.allocateDirect. It allows OS to read bytes from file to ByteBuffer directly, without copying

6) Parallel processing would definitely increase speed. Make a big byte buffer, run several tasks that read bytes from file into that buffer in parallel, when ready find first end of line, make a String, find next...

For right menu you can do it:

public static Drawable setTintDrawable(Drawable drawable, @ColorInt int color) {
            drawable.clearColorFilter();
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawable.invalidateSelf();
            Drawable wrapDrawable = DrawableCompat.wrap(drawable).mutate();
            DrawableCompat.setTint(wrapDrawable, color);
            return wrapDrawable;
        }

And in your activity

@Override
 public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_profile, menu);
        Drawable send = menu.findItem(R.id.send);
        Drawable msg = menu.findItem(R.id.message);
        DrawableUtils.setTintDrawable(send.getIcon(), Color.WHITE);
        DrawableUtils.setTintDrawable(msg.getIcon(), Color.WHITE);
        return true;
    }

This is the result:

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

Here's another solution that extends the "serializeArray" method (while preserving the original behavior).

//Store the reference to the original method:

var _serializeArray = $ji.fn.serializeArray;

//Now extend it with newer "unchecked checkbox" functionality:
$ji.fn.extend({
    serializeArray: function () {
        //Important: Get the results as you normally would...
        var results = _serializeArray.call(this);

        //Now, find all the checkboxes and append their "checked" state to the results.
        this.find('input[type=checkbox]').each(function (id, item) {
            var $item = $ji(item);
            var item_value = $item.is(":checked") ? 1 : 0;
            var item_name = $item.attr('name');
            var result_index = null;
            results.each(function (data, index) {
                if (data.name == item_name) {
                    result_index = index;
                }
            });

            if (result_index != null) {
                // FOUND replace previous value
                results[result_index].value = item_value;
            }
            else {
                // NO value has been found add new one
                results.push({name: item_name, value: item_value});
            }
        });
        return results;
    }
});

This will actually append "true" or "false" boolean results, but if you prefer you can use "1" and "0" respectively, by changing the value to value: $item.is(":checked") ? 1 : 0.

Usage

Just as usual, call the method on your form: $form.serialize() or $form.serializeArray(). What happens is that serialize makes use of serializeArray anyways, so you get the proper results (although different format) with whichever method you call.

If Foo is the class enclose this method

class Foo{
  public ArrayList<Integer> myNumbers()    {
     //code code code
  }
}

then

new Foo().myNumbers();

await blob.arrayBuffer() is good.

The problem is when iOS / Safari support is needed.. for that one would need this:

Blob.prototype.arrayBuffer ??=function(){ return new Response(this).arrayBuffer() }

I was trying to do this as I wanted to use a records "title" as an id in the view but the titles had spaces.

a solution is:

record.value.delete(' ') # Foo Bar -> FooBar

In C char gets promoted to int in expressions. That pretty much explains every question, if you think about it.

Source: The C Programming Language by Brian W.Kernighan and Dennis M.Ritchie

A must read if you want to learn C.

Also see this stack overflow page, where people much more experienced then me can explain it much better then I ever can.

Try running the following code:

List<String> listOfString = Arrays.asList("Hello", "World");
ArrayList<String> arrayListOfString = new ArrayList(listOfString);
System.out.println(listOfString.getClass());
System.out.println(arrayListOfString.getClass());

You'll get the following result:

class java.util.Arrays$ArrayList
class java.util.ArrayList

So, that means they're 2 different classes that aren't extending each other. java.util.Arrays$ArrayList signifies the private class named ArrayList (inner class of Arrays class) and java.util.ArrayList signifies the public class named ArrayList. Thus, casting from java.util.Arrays$ArrayList to java.util.ArrayList and vice versa are irrelevant/not available.

If I had to guess, I'd say you installed the PPA 7.1.8 as CLI only (php7-cli). You're getting your version info from that, but your libapache2-mod-php package is still 14.04 main which is 5.6. Check your phpinfo in your browser to confirm the version. You might also consider migrating to Ubuntu 16.04 to get PHP 7.0 in main.

The Fill function uses a DataReader internally. If your consideration is "Which one is more efficient?", then using a DataReader in a tight loop that populates a collection record-by-record, is likely to be the same load on the system as using DataAdapter.Fill.

Another option that has not been shown yet is to split your class into two, wrapping a lightweight interface class around your original class in order to achieve the effect you are looking for:

class Test_Base {
    public Test_Base() {
        DoSomething();
    }
};

class Test : public Test_Base {
    public Test() : Test_Base() {
    }

    public Test(int count) : Test_Base() {
        DoSomethingWithCount(count);
    }
};

This could get messy if you have many constructors that must call their "next level up" counterpart, but for a handful of constructors, it should be workable.

Here is an AngularJS Factory version of @user850789's one:

    var Base64 = {
        // private property

        // public method for encoding
        encode: function (input) {
            var output = "";
            var chr1, chr2, chr3, enc1, enc2, enc3, enc4;
            var i = 0;

            input = Base64._utf8_encode(input);

            while (i < input.length) {

                chr1 = input.charCodeAt(i++);
                chr2 = input.charCodeAt(i++);
                chr3 = input.charCodeAt(i++);

                enc1 = chr1 >> 2;

The getActiveNetworkInfo() method of ConnectivityManager returns a NetworkInfo instance representing the first connected network interface it can find or null if none of the interfaces are connected. Checking if this method returns null should be enough to tell if an internet connection is available or not.

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager 
          = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

You will also need:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

in your android manifest.

Edit:

Note that having an active network interface doesn't guarantee that a particular networked service is available. Network issues, server downtime, low signal, captive portals, content filters and the like can all prevent your app from reaching a server. For instance you can't tell for sure if your app can reach Twitter until you receive a valid response from the Twitter service.

I would like to share my way of starting chrome - specificaly youtube tv - in full screen mode automatically, without the need of pressing F11. kiosk/fullscreen options doesn't seem to work (Version 41.0.2272.89). It has some steps though...

• Start chrome and navigate to page (www.youtube.com/tv)
• Drag the address from the address bar (the lock icon) to the desktop. It will create a shortcut.
• From chrome, open Apps (the icon with the multiple coloured dots)
• From desktop, drag the shortcut into the Apps space
• Right click on the new icon in Apps and select "Open fullscreen"
• Right click again on the icon in Apps and select "Create shortcuts..."
• Select for example Desktop and Create. A new shortcut will be created on desktop.

Now, whenever you click on this shortcut, chrome will start in fullscreen and at the page you defined. I guess you can put this shortcut in startup folder to run when windows starts, but I haven't tried it.

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

You can set a primary key on a text column. In phpMyAdmin, display the Structure of your table, click on Indexes, then ask to create the index on one column. Then choose PRIMARY, pick your TEXT column, but you have to put a length big enough so that its unique.

If you are looking for an answer where you can redirect specific url/s to http then please update your htaccess like below

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{THE_REQUEST} !/(home/panel/videos|user/profile) [NC] # Multiple urls
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTPS} on
RewriteCond %{THE_REQUEST} /(home/panel/videos|user/profile) [NC] # Multiple urls
RewriteRule ^ http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

It worked for me :)

*Note : This will show popup once per browser as the data is stored in browser memory.

Try HTML localStorage.

Methods :

• localStorage.getItem('key');
• localStorage.setItem('key','value');

$j(document).ready(function() {
    if(localStorage.getItem('popState') != 'shown'){
        $j('#popup').delay(2000).fadeIn();
        localStorage.setItem('popState','shown')
    }

    $j('#popup-close, #popup').click(function() // You are clicking the close button
    {
        $j('#popup').fadeOut(); // Now the pop up is hidden.
    });
});

What Mocha options are you using?

Maybe it is something to do with reporter (-R) or ui (-ui) being used?

console.log(msg);

works fine during my test runs, though sometimes mixed in a little goofy. Presumably due to the async nature of the test run.

Here are the options (mocha.opts) I'm using:

--require should
-R spec
--ui bdd

Hmm..just tested without any mocha.opts and console.log still works.

Simplest Way to sort array of object by multiple fields:

 let homes = [ {"h_id":"3",
   "city":"Dallas",
   "state":"TX",
   "zip":"75201",
   "price":"162500"},
  {"h_id":"4",
   "city":"Bevery Hills",
   "state":"CA",
   "zip":"90210",
   "price":"319250"},
  {"h_id":"6",
   "city":"Dallas",
   "state":"TX",
   "zip":"75000",
   "price":"556699"},
  {"h_id":"5",
   "city":"New York",
   "state":"NY",
   "zip":"00010",
   "price":"962500"}
  ];

homes.sort((a, b) => (a.city > b.city) ? 1 : -1);

Output: "Bevery Hills" "Dallas" "Dallas" "Dallas" "New York"

Although if you want a code that is compatible with both python2 and python3 you can use this:

import logging
try:
    1/0
except Exception as e:
    if hasattr(e, 'message'):
        logging.warning('python2')
        logging.error(e.message)
    else:
        logging.warning('python3')
        logging.error(e)

For one file:

git diff --no-index /dev/null new_file

For all new files:

for next in $( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null $next; done;

As alias:

alias gdnew="for next in \$( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null \$next; done;"

For all modified and new files combined as one command:

{ git --no-pager diff; gdnew }

git stash pop throws away the (topmost, by default) stash after applying it, whereas git stash apply leaves it in the stash list for possible later reuse (or you can then git stash drop it).

This happens unless there are conflicts after git stash pop, in which case it will not remove the stash, leaving it to behave exactly like git stash apply.

Another way to look at it: git stash pop is git stash apply && git stash drop.

According to the documentation, you can also set global environment variables if you later want to use the value of the variable in other parts of your script. In your case, it would be setting it in the root pipeline:

pipeline {
  ...
  environment {
    FILENAME = readFile ...
  }
  ...
}

I'd prefer to exit with double tap on the back button than with an exit Dialog.

In this solution, it show a toast when go back for the first time, warning that another back press will close the App. In this example less than 4 seconds.

private Toast toast;
private long lastBackPressTime = 0;

@Override
public void onBackPressed() {
  if (this.lastBackPressTime < System.currentTimeMillis() - 4000) {
    toast = Toast.makeText(this, "Press back again to close this app", 4000);
    toast.show();
    this.lastBackPressTime = System.currentTimeMillis();
  } else {
    if (toast != null) {
    toast.cancel();
  }
  super.onBackPressed();
 }
}

There are just two minor things here.

The first is in the following carousel indicator list items:

<li data-target="carousel" data-slide-to="0"></li>

You need to pass the data-target attribute a selector which means the ID must be prefixed with #. So change them to the following:

<li data-target="#carousel" data-slide-to="0"></li>

Secondly, you need to give the carousel a starting point so both the carousel indicator items and the carousel inner items must have one active class. Like this:

<ol class="carousel-indicators">
    <li data-target="#carousel" data-slide-to="0" class="active"></li>
    <!-- Other Items -->
</ol>
<div class="carousel-inner">
    <div class="item active">
        <img src="https://picsum.photos/1500/600?image=1" alt="Slide 1" />
    </div>
    <!-- Other Items -->
</div>

I moved workbench.xmi located at workspace/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi to a backup folder. Then started eclipse and waited for all background processes to finish. Then I closed eclipse and moved my backup copy of workbench.xmi back (overwriting the one created with the last launch). Eclipse launched fine and I got all my settings back.

Django 3.0

here is link how to customize error views

here is link how to render a view

in the urls.py (the main one, in project folder), put:

handler404 = 'my_app_name.views.custom_page_not_found_view'
handler500 = 'my_app_name.views.custom_error_view'
handler403 = 'my_app_name.views.custom_permission_denied_view'
handler400 = 'my_app_name.views.custom_bad_request_view'

and in that app (my_app_name) put in the views.py:

def custom_page_not_found_view(request, exception):
    return render(request, "errors/404.html", {})

def custom_error_view(request, exception=None):
    return render(request, "errors/500.html", {})

def custom_permission_denied_view(request, exception=None):
    return render(request, "errors/403.html", {})

def custom_bad_request_view(request, exception=None):
    return render(request, "errors/400.html", {})

NOTE: error/404.html is the path if you place your files into the projects (not the apps) template foldertemplates/errors/404.html so please place the files where you want and write the right path.

NOTE 2: After page reload, if you still see the old template, change in settings.py DEBUG=True, save it, and then again to False (to restart the server and collect the new files).

I would like to point everybody's attention to pathod

With a config (taken from their examples) of 200:b@100:dr you'll get a connection that randomly drops.

If everything you want to drop is owned by the same user, then you can use:

drop owned by the_user;

This will drop everything that the user owns.

That includes materialized views, views, sequences, triggers, schemas, functions, types, aggregates, operators, domains and so on (so, really: everything) that the_user owns (=created).

You have to replace the_user with the actual username, currently there is no option to drop everything for "the current user". The upcoming 9.5 version will have the option drop owned by current_user.

More details in the manual: http://www.postgresql.org/docs/current/static/sql-drop-owned.html

You could say

 $name ne ""

instead of

 length $name > 0

Here is the tutorial of achieving the result.

Example:

if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest')
{    
  exit;    
}
continue;

This checks if the HTTP_X_REQUESTED_WITH parameter is not empty and if it's equal to xmlhttprequest, then it will exit from the script.

I know this is an old question, but there is a simple, one line solution which works consistently for Chrome, Firefox, etc., as well as IE8 and above (and, for the most part, works on IE7 too - see http://www.quirksmode.org/css/selectors/ for details):

table td + td { border-left:2px solid red; }

The output is something like this:

Col1 | Col2 | Col3

What is making this work is that you are defining a border only on table cells which are adjacent to another table cell. In other words, you're applying the CSS to all cells in a row except the first one.

By applying a left border to the second through the last child, it gives the appearance of the line being "between" the cells.

For example : Data = "Tire cycle size 70 / 90 - 16"

i can search with "70 90 16"

$searchTerms = preg_split("/[\s,-\/?!]+/", $itemName);

foreach ($searchTerms as $term) {
        $term = trim($term);
            if (!empty($term)) {
            $searchTermBits[] = "name LIKE '%$term%'";

Use gettimeofday() or better clock_gettime()

After trying everything, Yowsup library worked for me. The bug that I was facing was recently fixed. Anyone trying to do something with Whatsapp should try it.

Here is the comparison between MD5 and SHA1. You can get a clear idea about which one is better.

WAMP stores the db data under WAMP\bin\mysql\mysql(version)\data. Where the WAMP folder itself is depends on where you installed it to (on xp, I believe it is directly in the main drive, for example c:\WAMP\...

If you deleted that folder, or if the uninstall deleted that folder, if you did not do a DB backup before the uninstall, you may be out of luck.

If you did do a backup though phpmyadmin, then login, and click the import tab, and browse to the backup file.

1. git log to find out the commit you want to revert

2. git push origin +7f6d03:master while 7f6d03 is the commit before the wrongly pushed commit. + was for force push

And that's it.

Here is a very good guide that solves your problem, easy and simple!

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);

rysnc can be useful to run on slow and unreliable connections. So if your download aborts in the middle of a large file rysnc will be able to continue from where it left off when invoked again.

Use rsync -vP username@host:/path/to/file .

The -P option preserves partially downloaded files and also shows progress.

As usual check man rsync

In addition to the answer posted by Tim Banks, which followed to solving my issue I had to edit one simple thing.

Someone else might have the same issue; I'm working with a Bootstrap dropdown in a dropdown. But the text can be wider as the current content at this point (and there aren't many good ways to resolve that through css).

I used:

$table.css({ position: "absolute", visibility: "hidden", display: "table" });

instead, which sets the container to a table which always scales in width if the contents are wider.

You can use JsonResponse with values. Simple example:

from django.http import JsonResponse

def some_view(request):
    data = list(SomeModel.objects.values())  # wrap in list(), because QuerySet is not JSON serializable
    return JsonResponse(data, safe=False)  # or JsonResponse({'data': data})

Or another approach with Django's built-in serializers:

from django.core import serializers
from django.http import HttpResponse

def some_view(request):
    qs = SomeModel.objects.all()
    qs_json = serializers.serialize('json', qs)
    return HttpResponse(qs_json, content_type='application/json')

In this case result is slightly different (without indent by default):

[
    {
        "model": "some_app.some_model",
        "pk": 1,
        "fields": {
            "name": "Elon",
            "age": 48,
            ...
        }
    },
    ...
]

I have to say, it is good practice to use something like marshmallow to serialize queryset.

...and a few notes for better performance:

• use pagination if your queryset is big;
• use objects.values() to specify list of required fields to avoid serialization and sending to client unnecessary model's fields (you also can pass fields to serializers.serialize);

You need to use the select new LINQ keyword to explicitly convert your tbcourseentity into the custom type course. Example of select new:

var q = from o in db.Orders
        where o.Products.ProductName.StartsWith("Asset") && 
              o.PaymentApproved == true
        select new { name   = o.Contacts.FirstName + " " +
                              o.Contacts.LastName, 
                     product = o.Products.ProductName, 
                     version = o.Products.Version + 
                              (o.Products.SubVersion * 0.1)
                   };

This should work:

DataTable dtTable;

MySQLProcessor.DTTable(mysqlCommand, out dtTable);

// On all tables' rows
foreach (DataRow dtRow in dtTable.Rows)
{
    // On all tables' columns
    foreach(DataColumn dc in dtTable.Columns)
    {
      var field1 = dtRow[dc].ToString();
    }
}

Quick, Simple and Error free method

i.e. You want to create a component in a app/common folder as shown in the image given below, then follow these steps

1. Right click on the folder in which you want to create component.
2. Select option Open in Integrated Terminal or Open in Command Prompt.
3. In new terminal (you'll see your selected path), then type ng g c my-component

Also you can check this process through this image

If you want to move from one origin to another and also keep a backup of your current origin on your local machine you could use these steps:

1. First locally go to the (git)folder you want to move over
2. Create the new repository online This step creates a repository where we can push code to

Now in the folder do

git remote get-url origin

The above command gives the current remote origin url, useful to set the origin back to in the last step

git remote set-url origin [email protected]:folder/newrepo.git

The above command sets the remote origin to the new location

git push --set-upstream origin develop

The above command pushes the current active local branch to remote with branchname develop. Of course it preserves all history as with git all history is also pushed.

git remote set-url origin <original old origin>

The above command sets back the remote origin to your current origin: you want this because you are in your existing folder and you probably do not want to mix up your current local folder name with the new folder you are going to create for cloning the repo you just pushed to.

Hope this helps,

Since PyCharm 3.4 the path tab in the 'Project Interpreter' settings has been replaced. In order to add paths to a project you need to select the cogwheel, click on 'More...' and then select the "Show path for the selected interpreter" icon. This allows you to add paths to your project as before.

My project is now behaving as I would expect.

A little modification to typescript:

  public encodeData(data: any): string {
    return Object.keys(data).map((key) => {
      return [key, data[key]].map(encodeURIComponent).join("=");
    }).join("&");
  }

I could not find a standard control and had 0 intention to use a library such as bootstrap select so I custom made this widget. Bootstrap 4 allows you to add forms inside your dropdown which is what I have used here. I added a search box, used an input event to capture the text entered by the user inside the box, If the phrase entered by the user starts with the items inside the box, I show the items else I hide them. I also handle the click event on any item to change the text of the dropdown button

UPDATE 1

The code above uses show() and hide() inside a loop which is why the UI is slow when you clear everything you typed in case you didn't notice. Instead of that, use .css({display: 'none'}) and .css({display: 'block'})

$('selector').css('cursor', 'pointer'); // 'default' to revert

I know that may be confusing per your original question, but the "finger" cursor is actually called "pointer".

The normal arrow cursor is just "default".

all possible default pointer looks DEMO

I will provide a simple and general answer that works with any number of audios and srt subtitles and respects the metadata that may include the mkv container. So it will even add the images the matroska may include as attachments (though not another types AFAIK) and convert them to tracks; you will not be able to watch but they will be there (you can demux them). Ah, and if the mkv has chapters the mp4 too.

ffmpeg -i <mkv-input> -c copy -map 0 -c:s mov_text <mp4-output>

As you can see, it's all about the -map 0, that tells FFmpeg to add all the tracks, which includes metadata, chapters, attachments, etc. If there is an unrecognized "track" (mkv allows to attach any type of file), it will end with an error.

You can create a simple batch mkv2mp4.bat, if you usually do this, to create an mp4 with the same name as the mkv. It would be better with error control, a different output name, etc., but you get the point.

@ffmpeg -i %1 -c copy -map 0 -c:s mov_text "%~n1.mp4"

Now you can simply run

mkv2mp4 "Video with subtitles etc.mkv"

And it will create "Video with subtitles etc.mp4" with the maximum of information included.

The differences between the two, though subtle, are significant:

.closest()

• Begins with the current element
• Travels up the DOM tree until it finds a match for the supplied selector
• The returned jQuery object contains zero or one element

.parents()

• Begins with the parent element
• Travels up the DOM tree to the document's root element, adding each ancestor element to a temporary collection; it then filters that collection based on a selector if one is supplied
• The returned jQuery object contains zero, one, or multiple elements

From jQuery docs

Those are unicode escapes. The general unicode escapes looks like \uxxxx where xxxx are the hexadecimal digits of the ASCI characters. They are used mainly to insert special characters inside a javascript string.

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

As for your regexp I guess it should be

^\+{0,2}([\-\. ])?(\(?\d{0,3}\))?([\-\. ])?\(?\d{0,3}\)?([\-\. ])?\d{3}([\-\. ])?\d{4}

But in general the presumption is not correct because one might enter something like ++44 20 1234 56789 or +44 (0) 1234 567890 it is better to do something like this

var phone = document.forms["myForm"]["phone"].value;
var phoneNum = phone.replace(/[^\d]/g, '');
if(phoneNum.length > 6 && phoneNum.length < 11) {  return true;  }

this will assure that entered value has 7 to 10 figures nevertheless what the formatting is. But you have to think about max length for number might be more than 10 as in the sample above.

For a continuous variable/measure 'col1' from 'table1'

select col1  
from
    (select top 50 percent col1, 
    ROW_NUMBER() OVER(ORDER BY col1 ASC) AS Rowa,
    ROW_NUMBER() OVER(ORDER BY col1 DESC) AS Rowd
    from table1 ) tmp
where tmp.Rowa = tmp.Rowd

Since this question was originally asked, Google's Guava library now includes a powerful and flexible cache. I would recommend using this.

std::vector<CustomClass *> whatever(20000);

or:

std::vector<CustomClass *> whatever;
whatever.reserve(20000);

The former sets the actual size of the array -- i.e., makes it a vector of 20000 pointers. The latter leaves the vector empty, but reserves space for 20000 pointers, so you can insert (up to) that many without it having to reallocate.

At least in my experience, it's fairly unusual for either of these to make a huge difference in performance--but either can affect correctness under some circumstances. In particular, as long as no reallocation takes place, iterators into the vector are guaranteed to remain valid, and once you've set the size/reserved space, you're guaranteed there won't be any reallocations as long as you don't increase the size beyond that.

Short answer...yes. You can use an anonymous class when you initialize a variable. Take a look at this question: Anonymous vs named inner classes? - best practices?

Spans are inline, divs are block elements. i.e. spans are only as wide as their respective content. You can align the span inside the surrounding container (if it's a block container), but you can't align the content.

Span is primarily used for formatting purposes. If you want to arrange or position the contents, use div, p or some other block element.

I was having the same sort of problem. Apparently it's simply because PHP doesn't recognise utf-8.

I was tearing my hair out at first when a '£' sign kept showing up as '£', despite it appearing ok in DreamWeaver. Eventually I remembered I had been having problems with links relative to the index file, when the pages, if viewed directly would work with slideshows, but not when used with an include (but that's beside the point. Anyway I wondered if this might be a similar problem, so instead of putting into the page that I was having problems with, I simply put it into the index.php file - problem fixed throughout.

A good style would be to setup some relations and a primary key for permissions (actually, usually it is good style to setup integer primary keys for everything, but whatever):

class User(Base):
    __tablename__ = 'users'
    email = Column(String, primary_key=True)
    name = Column(String)

class Document(Base):
    __tablename__ = "documents"
    name = Column(String, primary_key=True)
    author_email = Column(String, ForeignKey("users.email"))
    author = relation(User, backref='documents')

class DocumentsPermissions(Base):
    __tablename__ = "documents_permissions"
    id = Column(Integer, primary_key=True)
    readAllowed = Column(Boolean)
    writeAllowed = Column(Boolean)
    document_name = Column(String, ForeignKey("documents.name"))
    document = relation(Document, backref = 'permissions')

Then do a simple query with joins:

query = session.query(User, Document, DocumentsPermissions).join(Document).join(DocumentsPermissions)

Remove those char * ret declarations inside if blocks which hide outer ret. Therefor you have memory leak and on the other hand un-allocated memory for ret.

To compare a c-style string you should use strcmp(array,"") not array!="". Your final code should looks like below:

char* appendCharToCharArray(char* array, char a)
{
    size_t len = strlen(array);

    char* ret = new char[len+2];

    strcpy(ret, array);    
    ret[len] = a;
    ret[len+1] = '\0';

    return ret;
}

Note that, you must handle the allocated memory of returned ret somewhere by delete[] it.

Why you don't use std::string? it has .append method to append a character at the end of a string:

std::string str;

str.append('x');
// or
str += x;

function is_associative($arr) {
  return (array_merge($arr) !== $arr || count(array_filter($arr, 'is_string', ARRAY_FILTER_USE_KEY)) > 0);
}

Here is one method:

<bean id="stage1" class="Stageclass"/>
<bean id="stage2" class="Stageclass"/>

<bean id="stages" class="java.util.ArrayList">
    <constructor-arg>
        <list>
            <ref bean="stage1" />
            <ref bean="stage2" />                
        </list>
    </constructor-arg>
</bean>

You need %in% instead of ==:

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

Produces

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

To understand why, consider what happens here:

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

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

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

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

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

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

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

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

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

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

I found another way to solve this one to avoid password of VBA Project,with out loosing excel password.

use Hex-editor XVI32 for the process

if the file type is XLSM files:

1. Open the XLSM file with 7-Zip (right click -> 7-Zip -> Open archive).
2. Copy the xl/vbaProject.bin file out of the file (you can drag and drop from 7-Zip), don't close 7-Zip
3. Open the vbaProject.bin file with HexEdit
4. Search for "DPB=" and replace it with "DPx="
5. Save the file
6. Copy this file back into 7-Zip (again, drag and drop works)
7. Open the XLSX file in Excel, if prompted to "Continue Loading Project", click Yes. If prompted with errors, click OK.
8. Press Alt+ F11 to open the VBA editor.
9. While press it will show error “Unexpected error (40230)”, just click OK (6 or 7 times) until it goes away.
10. Then it will open Automatically

Avoid using Activity implements OnMarkerClickListener, use a local OnMarkerClickListener

// Not a good idea
class MapActivity extends Activity implements OnMarkerClickListener {
}

You will need a map to lookup the original data model linked to the marker

private Map<Marker, Map<String, Object>> markers = new HashMap<>();

You will need a data model

private Map<String, Object> dataModel = new HashMap<>();

Put some data in the data model

dataModel.put("title", "My Spot");
dataModel.put("snipet", "This is my spot!");
dataModel.put("latitude", 20.0f);
dataModel.put("longitude", 100.0f);

When creating a new marker using a data model add both to the maker map

Marker marker = googleMap.addMarker(markerOptions);
markers.put(marker, dataModel);

For on click marker event, use a local OnMarkerClickListener:

@Override
public void onMapReady(GoogleMap googleMap) {
    // grab for laters
    this.googleMap = googleMap;

    googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            Map dataModel = (Map)markers.get(marker);
            String title = (String)dataModel.get("title");
            markerOnClick(title);

            return false;
        }
    });

    mapView.onResume();

    showMarkers();

    ZoomAsync zoomAsync = new ZoomAsync();
    zoomAsync.execute();
}

For displaying the info window retrieve the original data model from the marker map:

@Override
public void onMapReady(GoogleMap googleMap) {
    this.googleMap = googleMap;
    googleMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
        @Override
        public void onInfoWindowClick(Marker marker) {
            Map dataModel = (Map)markers.get(marker);
            String title = (String)dataModel.get("title");

            infoWindowOnClick(title);
        }
    });

I didnt see this question answered:

How should I setup a default Area when the application starts?

So, here is how you can set up a default Area:

var route = routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    ).DataTokens = new RouteValueDictionary(new { area = "MyArea" });

Even my Intellisense in Pycharm was not working for modules like time Problem in my system was no Interpreter was selected Go to File --> Settings... (Ctrl+Alt+S) Open Project Interpreter

Project Interpreter In my case was selected. I selected the available python interpreter. If not available you can add a new interpreter.

I'll interpret your question as two questions: 1) why -> even exists, and 2) why . does not automatically dereference the pointer. Answers to both questions have historical roots.

Why does -> even exist?

In one of the very first versions of C language (which I will refer as CRM for "C Reference Manual", which came with 6th Edition Unix in May 1975), operator -> had very exclusive meaning, not synonymous with * and . combination

The C language described by CRM was very different from the modern C in many respects. In CRM struct members implemented the global concept of byte offset, which could be added to any address value with no type restrictions. I.e. all names of all struct members had independent global meaning (and, therefore, had to be unique). For example you could declare

struct S {
  int a;
  int b;
};

and name a would stand for offset 0, while name b would stand for offset 2 (assuming int type of size 2 and no padding). The language required all members of all structs in the translation unit either have unique names or stand for the same offset value. E.g. in the same translation unit you could additionally declare

struct X {
  int a;
  int x;
};

and that would be OK, since the name a would consistently stand for offset 0. But this additional declaration

struct Y {
  int b;
  int a;
};

would be formally invalid, since it attempted to "redefine" a as offset 2 and b as offset 0.

And this is where the -> operator comes in. Since every struct member name had its own self-sufficient global meaning, the language supported expressions like these

int i = 5;
i->b = 42;  /* Write 42 into `int` at address 7 */
100->a = 0; /* Write 0 into `int` at address 100 */

The first assignment was interpreted by the compiler as "take address 5, add offset 2 to it and assign 42 to the int value at the resultant address". I.e. the above would assign 42 to int value at address 7. Note that this use of -> did not care about the type of the expression on the left-hand side. The left hand side was interpreted as an rvalue numerical address (be it a pointer or an integer).

This sort of trickery was not possible with * and . combination. You could not do

(*i).b = 42;

since *i is already an invalid expression. The * operator, since it is separate from ., imposes more strict type requirements on its operand. To provide a capability to work around this limitation CRM introduced the -> operator, which is independent from the type of the left-hand operand.

As Keith noted in the comments, this difference between -> and *+. combination is what CRM is referring to as "relaxation of the requirement" in 7.1.8: Except for the relaxation of the requirement that E1 be of pointer type, the expression E1->MOS is exactly equivalent to (*E1).MOS

Later, in K&R C many features originally described in CRM were significantly reworked. The idea of "struct member as global offset identifier" was completely removed. And the functionality of -> operator became fully identical to the functionality of * and . combination.

Why can't . dereference the pointer automatically?

Again, in CRM version of the language the left operand of the . operator was required to be an lvalue. That was the only requirement imposed on that operand (and that's what made it different from ->, as explained above). Note that CRM did not require the left operand of . to have a struct type. It just required it to be an lvalue, any lvalue. This means that in CRM version of C you could write code like this

struct S { int a, b; };
struct T { float x, y, z; };

struct T c;
c.b = 55;

In this case the compiler would write 55 into an int value positioned at byte-offset 2 in the continuous memory block known as c, even though type struct T had no field named b. The compiler would not care about the actual type of c at all. All it cared about is that c was an lvalue: some sort of writable memory block.

Now note that if you did this

S *s;
...
s.b = 42;

the code would be considered valid (since s is also an lvalue) and the compiler would simply attempt to write data into the pointer s itself, at byte-offset 2. Needless to say, things like this could easily result in memory overrun, but the language did not concern itself with such matters.

I.e. in that version of the language your proposed idea about overloading operator . for pointer types would not work: operator . already had very specific meaning when used with pointers (with lvalue pointers or with any lvalues at all). It was very weird functionality, no doubt. But it was there at the time.

Of course, this weird functionality is not a very strong reason against introducing overloaded . operator for pointers (as you suggested) in the reworked version of C - K&R C. But it hasn't been done. Maybe at that time there was some legacy code written in CRM version of C that had to be supported.

(The URL for the 1975 C Reference Manual may not be stable. Another copy, possibly with some subtle differences, is here.)

You might want to look at setting up a jail.

You are checking it the array index contains a string "undefined", you should either use the typeof operator:

typeof predQuery[preId] == 'undefined'

Or use the undefined global property:

predQuery[preId] === undefined

The first way is safer, because the undefined global property is writable, and it can be changed to any other value.

If you are using MySQL

public static boolean isDbConnected() {
    final String CHECK_SQL_QUERY = "SELECT 1";
    boolean isConnected = false;
    try {
        final PreparedStatement statement = db.prepareStatement(CHECK_SQL_QUERY);
        isConnected = true;
    } catch (SQLException | NullPointerException e) {
        // handle SQL error here!
    }
    return isConnected;
}

I have not tested with other databases. Hope this is helpful.

The practical way is setting font-family to a value that is the specific name of the semibold version, such as

font-family: "Myriad pro Semibold"

if that’s the name. (Personally I use my own font listing tool, which runs on Internet Explorer only to see the fonts in my system by names as usable in CSS.)

In this approach, font-weight is not needed (and probably better not set).

Web browsers have been poor at implementing font weights by the book: they largely cannot find the specific weight version, except bold. The workaround is to include the information in the font family name, even though this is not how things are supposed to work.

Testing with Segoe UI, which often exists in different font weight versions on Windows systems, I was able to make Internet Explorer 9 select the proper version when using the logical approach (of using the font family name Segoe UI and different font-weight values), but it failed on Firefox 9 and Chrome 16 (only normal and bold work). On all of these browsers, for example, setting font-family: Segoe UI Light works OK.

you can also try this in sql-server !!

select a.city,a.total + b.total as mytotal from [dbo].[cash] a join [dbo].[cheque] b on a.city=b.city 

demo

or try using sum,union

select sum(total)  as mytotal,city
from
(
    select * from cash union
    select * from cheque
) as vij
group by city 

You could maybe add

.print:last-child {
     page-break-after: auto;
}

so the last print element will not get the extra page break.

Do note that the :last-child selector is not supported in IE8, if you're targetting that wretch of a browser.

Almost all of these have issues when the user tries to backspace over the delimiters, particularly from the middle of the string.

Here's a jquery solution that handles that, and also makes sure the cursor stays in the right place as you edit:

//format text input as phone number (nnn) nnn-nnnn
$('.myPhoneField').on('input', function (e){
    var $phoneField = e.target;
    var cursorPosition = $phoneField.selectionStart;
    var numericString = $phoneField.value.replace(/\D/g, '').substring(0, 10);

    // let user backspace over the '-'
    if (cursorPosition === 9 && numericString.length > 6) return;

    // let user backspace over the ') '
    if (cursorPosition === 5 && numericString.length > 3) return;
    if (cursorPosition === 4 && numericString.length > 3) return;

    var match = numericString.match(/^(\d{1,3})(\d{0,3})(\d{0,4})$/);
    if (match) {
        var newVal = '(' + match[1];
        newVal += match[2] ? ') ' + match[2] : '';
        newVal += match[3] ? '-' + match[3] : '';

        // to help us put the cursor back in the right place
        var delta = newVal.length - Math.min($phoneField.value.length, 14);      
        $phoneField.value = newVal;
        $phoneField.selectionEnd = cursorPosition + delta;
    } else {
        $phoneField.value = '';        
    }
})

I added +/- 10-15% efficiency to the selected answer by minor code refactoring and moving the recursive function outside of the function namespace.

See my question: Are namespaced functions reevaluated on every call? for why this slows nested functions down.

function _flatten (target, obj, path) {
  var i, empty;
  if (obj.constructor === Object) {
    empty = true;
    for (i in obj) {
      empty = false;
      _flatten(target, obj[i], path ? path + '.' + i : i);
    }
    if (empty && path) {
      target[path] = {};
    }
  } 
  else if (obj.constructor === Array) {
    i = obj.length;
    if (i > 0) {
      while (i--) {
        _flatten(target, obj[i], path + '[' + i + ']');
      }
    } else {
      target[path] = [];
    }
  }
  else {
    target[path] = obj;
  }
}

function flatten (data) {
  var result = {};
  _flatten(result, data, null);
  return result;
}

See benchmark.

Instead of making a touchable UIImageView then placing it on the navbar, you should just create a UIBarButtonItem, which you make out of a UIImageView.

First make the image view:

UIImageView *yourImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"nameOfYourImage.png"]];

Then make the barbutton item out of your image view:

UIBarButtonItem *yourBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:yourImageView];

Then add the bar button item to your navigation bar:

self.navigationItem.rightBarButtonItem = yourBarButtonItem;

Remember that this code goes into the view controller which is inside a navigation controller viewcontroller array. So basically, this "touchable image-looking bar button item" will only appear in the navigation bar when this view controller when it's being shown. When you push another view controller, this navigation bar button item will disappear.

const [name, setName] = useState()

generates error as soon as you type in the text field

const [name, setName] = useState('') // <-- by putting in quotes 

will fix the issue on this string example.

This code might help to this topic. Simple, yet useful.

<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.1.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
        setInterval("$('#myID/.myClass').toggle();",500);
    });
</script>

Crossframe-Scripting is not possible when the two frames have different domains -> Security.

See this: http://javascript.about.com/od/reference/a/frame3.htm

Now to answer your question: there is no solution or work around, you simply should check your website-design why there must be two frames from different domains that changes the url of the other one.

var countries = ['United States', 'Canada', 'Argentina', 'Armenia'];
var cList = $('ul.mylist')
$.each(countries, function(i)
{
    var li = $('<li/>')
        .addClass('ui-menu-item')
        .attr('role', 'menuitem')
        .appendTo(cList);
    var aaa = $('<a/>')
        .addClass('ui-all')
        .text(countries[i])
        .appendTo(li);
});

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

From the MSDN library:

The First<TSource>(IEnumerable<TSource>) method throws an exception if source contains no elements. To instead return a default value when the source sequence is empty, use the FirstOrDefault method.

use this style

min-height:250px;
height:auto;

A normal broadcast Intent is not available anymore after is was send and processed by the system. If you use the sendStickyBroadcast(Intent) method, the Intent is sticky, meaning the Intent you are sending stays around after the broadcast is complete.

you refer to my blog:enter link description here

If you wanna find just the word like 'are' in "How are you?" and not like 'are' in 'hare'

$word=" are ";
$str="How are you?";
if(strpos($word,$str) !== false){
echo 1;
 }

I wrote this method for me. I use some part of Bruno Ratnieks's code. Maybe it is useful to someone.

 public static string getQueryFromCommand(SqlCommand cmd)
    {
        StringBuilder CommandTxt = new StringBuilder();
        CommandTxt.Append("DECLARE ");
        List<string> paramlst = new List<string>();
        foreach (SqlParameter parms in cmd.Parameters)
        {
            paramlst.Add(parms.ParameterName);
            CommandTxt.Append(parms.ParameterName + " AS ");
            CommandTxt.Append(parms.SqlDbType.ToString());
            CommandTxt.Append(",");
        }

        if (CommandTxt.ToString().Substring(CommandTxt.Length-1, 1) == ",")
            CommandTxt.Remove(CommandTxt.Length-1, 1);
        CommandTxt.AppendLine();
        int rownr = 0;
        foreach (SqlParameter parms in cmd.Parameters)
        {
            string val = String.Empty;
            if (parms.DbType.Equals(DbType.String) || parms.DbType.Equals(DbType.DateTime))
                val = "'" + Convert.ToString(parms.Value).Replace(@"\", @"\\").Replace("'", @"\'") + "'";
            if (parms.DbType.Equals(DbType.Int16) || parms.DbType.Equals(DbType.Int32) || parms.DbType.Equals(DbType.Int64) || parms.DbType.Equals(DbType.Decimal) || parms.DbType.Equals(DbType.Double))
                val = Convert.ToString(parms.Value);

            CommandTxt.AppendLine();
            CommandTxt.Append("SET " + paramlst[rownr].ToString() + " = " + val.ToString());
            rownr += 1;
        }
        CommandTxt.AppendLine();
        CommandTxt.AppendLine();
        CommandTxt.Append(cmd.CommandText);
        return CommandTxt.ToString();
    }

$mail->SMTPDebug = 2; // to see exactly what's the issue

In my case this helped:

$mail->SMTPSecure = false;
$mail->SMTPAutoTLS = false;

1. The reason this is failing is because (Python 3) input returns a string. To convert it to an integer, use int(some_string).

2. You do not typically keep track of indices manually in Python. A better way to implement such a function would be

   def cat_n_times(s, n):
       for i in range(n):
           print(s) 
   
   text = input("What would you like the computer to repeat back to you: ")
   num = int(input("How many times: ")) # Convert to an int immediately.
   
   cat_n_times(text, num)
   

3. I changed your API above a bit. It seems to me that n should be the number of times and s should be the string.

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

Unless one want a separate function in global namespacs, we can use lambda functions for creating threads.

One of the major advantage of creating thread using lambda is that we don't need to pass local parameters as an argument list. We can use capture list for the same and the closure property of lambda will take care of the lifecycle.

Here is a sample code

int main() {
    int localVariable = 100;

    thread th { [=](){
        cout<<"The Value of local variable => "<<localVariable<<endl;
    }};

    th.join();

    return 0;
}

By far, I've found C++ lambdas to be the best way of creating threads especially for simpler thread functions

I would suggest this:

def softmax(z):
    z_norm=np.exp(z-np.max(z,axis=0,keepdims=True))
    return(np.divide(z_norm,np.sum(z_norm,axis=0,keepdims=True)))

It will work for stochastic as well as the batch.
