you can use Dependency Walker to view the function name. you can see the function's parameters only if it's decorated. read the following from the FAQ:

How do I view the parameter and return types of a function? For most functions, this information is simply not present in the module. The Windows' module file format only provides a single text string to identify each function. There is no structured way to list the number of parameters, the parameter types, or the return type. However, some languages do something called function "decoration" or "mangling", which is the process of encoding information into the text string. For example, a function like int Foo(int, int) encoded with simple decoration might be exported as _Foo@8. The 8 refers to the number of bytes used by the parameters. If C++ decoration is used, the function would be exported as ?Foo@@YGHHH@Z, which can be directly decoded back to the function's original prototype: int Foo(int, int). Dependency Walker supports C++ undecoration by using the Undecorate C++ Functions Command.

functions that implement native code are declared native.

The Java Native Interface (JNI) is a programming framework that enables Java code running in a Java Virtual Machine (JVM) to call, and to be called by, native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.

http://en.wikipedia.org/wiki/Java_Native_Interface

I like to know where does we use Native Methods

Ideally, not at all. In reality some functionality is not available in Java and you have to call some C code.

The methods are implemented in C code.

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS 
   (SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)

or

SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN 
    (SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)

or

SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B 
    ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL

Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

In C, if time efficiency is crucial and integer overflows will wrap, one could do if ((unsigned)(value-min) <= (max-min)) .... If 'max' and 'min' are independent variables, the extra subtraction for (max-min) will waste time, but if that expression can be precomputed at compile time, or if it can be computed once at run-time to test many numbers against the same range, the above expression may be computed efficiently even in the case where the value is within range (if a large fraction of values will be below the valid range, it may be faster to use if ((value >= min) && (value <= max)) ... because it will exit early if value is less than min).

Before using an implementation like that, though, benchmark one one's target machine. On some processors, the two-part expression may be faster in all cases since the two comparisons may be done independently whereas in the subtract-and-compare method the subtraction has to complete before the compare can execute.

There's 3 ways to clear file input with javascript:

1. set value property to empty or null.

   Works for IE11+ and other modern browsers.

2. Create an new file input element and replace the old one.

   The disadvantage is you will lose event listeners and expando properties.

3. Reset the owner form via form.reset() method.

   To avoid affecting other input elements in the same owner form, we can create an new empty form and append the file input element to this new form and reset it. This way works for all browsers.

I wrote a javascript function. demo: http://jsbin.com/muhipoye/1/

function clearInputFile(f){
    if(f.value){
        try{
            f.value = ''; //for IE11, latest Chrome/Firefox/Opera...
        }catch(err){ }
        if(f.value){ //for IE5 ~ IE10
            var form = document.createElement('form'),
                parentNode = f.parentNode, ref = f.nextSibling;
            form.appendChild(f);
            form.reset();
            parentNode.insertBefore(f,ref);
        }
    }
}

Use java -cp myjar.jar com.mypackage.myClass.

1. If the class is not in a package then simply java -cp myjar.jar myClass.

2. If you are not within the directory where myJar.jar is located, then you can do:

   1. On Unix or Linux platforms:

      java -cp /location_of_jar/myjar.jar com.mypackage.myClass

   2. On Windows:

      java -cp c:\location_of_jar\myjar.jar com.mypackage.myClass

There's also Fody which has a PropertyChanged add-in, which lets you write this:

[ImplementPropertyChanged]
public class Person 
{        
    public string GivenNames { get; set; }
    public string FamilyName { get; set; }
}

...and at compile time injects property changed notifications.

Here's a great reason to use objectForKey: wherever possible instead of valueForKey: - valueForKey: with an unknown key will throw NSUnknownKeyException saying "this class is not key value coding-compliant for the key ".

Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8

Since exit() ultimately “only” raises an exception, it will only exit the process when called from the main thread, and the exception is not intercepted. (doc)

This answer from Alex Martelli for more details.

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

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

Do I need to double the size of the .box div to 400px by 400px to match the new high res background image

No, but you do need to set the background-size property to match the original dimensions:

@media (-webkit-min-device-pixel-ratio: 2), 
(min-resolution: 192dpi) { 

    .box{
        background:url('images/[email protected]') no-repeat top left;
        background-size: 200px 200px;
    }
}

EDIT

To add a little more to this answer, here is the retina detection query I tend to use:

@media
only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and (   min--moz-device-pixel-ratio: 2),
only screen and (     -o-min-device-pixel-ratio: 2/1),
only screen and (        min-device-pixel-ratio: 2),
only screen and (                min-resolution: 192dpi),
only screen and (                min-resolution: 2dppx) { 

}

- Source

NB. This min--moz-device-pixel-ratio: is not a typo. It is a well documented bug in certain versions of Firefox and should be written like this in order to support older versions (prior to Firefox 16). - Source

As @LiamNewmarch mentioned in the comments below, you can include the background-size in your shorthand background declaration like so:

.box{
    background:url('images/[email protected]') no-repeat top left / 200px 200px;
}

However, I personally would not advise using the shorthand form as it is not supported in iOS <= 6 or Android making it unreliable in most situations.

Full Outer join don't exist in mysql , you might need to use a combination of left and right join.

l = [1,2,3,4,5]
sum = 0
for x in l:
    sum = sum + x

And you can change l for any list you want.

The first result in your MSDN search said:

The method group identifies the one method to invoke or the set of overloaded methods from which to choose a specific method to invoke

my understanding is that basically because when you just write someInteger.ToString, it may refer to:

Int32.ToString(IFormatProvider) 

or it can refer to:

Int32.ToString()

so it is called a method group.

Code Snippet1:

NSMutableArray *array = [[NSMutableArray alloc] init];
NSArray * values = [dictionary allValues];
[array addObject:values];

Code Snippet2: If you want to add further

[array addObject:value1];
[array addObject:value2];
[array addObject:value3];

And so on

Also you can store key values of dictionary to array

NSArray *keys = [dictionary allKeys];

Removing a file from pull request but not from your local repository.

You have a lot of unnecessary keyframes. Don't think of keyframes as individual frames, think of them as "steps" in your animation and the computer fills in the frames between the keyframes.

Here is a solution that cleans up a lot of code and makes the animation start from the center:

.gps_ring {
    border: 3px solid #999;
    -webkit-border-radius: 30px;
    height: 18px;
    width: 18px;
    position: absolute;
    left:20px;
    top:214px;
    -webkit-animation: pulsate 1s ease-out;
    -webkit-animation-iteration-count: infinite; 
    opacity: 0.0
}
@-webkit-keyframes pulsate {
    0% {-webkit-transform: scale(0.1, 0.1); opacity: 0.0;}
    50% {opacity: 1.0;}
    100% {-webkit-transform: scale(1.2, 1.2); opacity: 0.0;}
}

You can see it in action here: http://jsfiddle.net/Fy8vD/

To check if a lateinit var were initialised or not use a .isInitialized on the reference to that property:

if (foo::bar.isInitialized) {
    println(foo.bar)
}

This checking is only available for the properties that are accessible lexically, i.e. declared in the same type or in one of the outer types, or at top level in the same file.

Copied from the formal specification: ECMAScript 5.1 section 11.9.5

11.9.4 The Strict Equals Operator ( === )

The production EqualityExpression : EqualityExpression === RelationalExpression is evaluated as follows:

1. Let lref be the result of evaluating EqualityExpression.
2. Let lval be GetValue(lref).
3. Let rref be the result of evaluating RelationalExpression.
4. Let rval be GetValue(rref).
5. Return the result of performing the strict equality comparison rval === lval. (See 11.9.6)

11.9.5 The Strict Does-not-equal Operator ( !== )

The production EqualityExpression : EqualityExpression !== RelationalExpression is evaluated as follows:

1. Let lref be the result of evaluating EqualityExpression.
2. Let lval be GetValue(lref).
3. Let rref be the result of evaluating RelationalExpression.
4. Let rval be GetValue(rref). Let r be the result of performing strict equality comparison rval === lval. (See 11.9.6)
5. If r is true, return false. Otherwise, return true.

11.9.6 The Strict Equality Comparison Algorithm

The comparison x === y, where x and y are values, produces true or false. Such a comparison is performed as follows:

1. If Type(x) is different from Type(y), return false.
2. Type(x) is Undefined, return true.
3. Type(x) is Null, return true.
4. Type(x) is Number, then
   1. If x is NaN, return false.
   2. If y is NaN, return false.
   3. If x is the same Number value as y, return true.
   4. If x is +0 and y is -0, return true.
   5. If x is -0 and y is +0, return true.
   6. Return false.
5. If Type(x) is String, then return true if x and y are exactly the same sequence of characters (same length and same characters in corresponding positions); otherwise, return false.
6. If Type(x) is Boolean, return true if x and y are both true or both false; otherwise, return false.
7. Return true if x and y refer to the same object. Otherwise, return false.

Not sure if this is faster, but at least it's shorter :)

int rows = new DataView(dtFoo, "IsActive = 'Y'", "IsActive",

ctypes will be the easiest thing to use but (mis)using it makes Python subject to crashing. If you are trying to do something quickly, and you are careful, it's great.

I would encourage you to check out Boost Python. Yes, it requires that you write some C++ code and have a C++ compiler, but you don't actually need to learn C++ to use it, and you can get a free (as in beer) C++ compiler from Microsoft.

You mean like

$target.hide('slow')

?

Try this:

int getYear(Date date1,Date date2){ 
      SimpleDateFormat simpleDateformat=new SimpleDateFormat("yyyy");
      Integer.parseInt(simpleDateformat.format(date1));

      return Integer.parseInt(simpleDateformat.format(date2))- Integer.parseInt(simpleDateformat.format(date1));

    }

My answer:

file_path = 'myfile.dat'
try:
    fp = open(file_path)
except IOError:
    # If not exists, create the file
    fp = open(file_path, 'w+')

You created the directory in the wrong place

/data/db means that it's directly under the '/' root directory, whereas you created 'data/db' (without the leading /) probably just inside another directory, such as the '/root' homedirectory.

You need to create this directory as root

Either you need to use sudo , e.g. sudo mkdir -p /data/db

Or you need to do su - to become superuser, and then create the directory with mkdir -p /data/db

Note:

MongoDB also has an option where you can create the data directory in another location, but that's generally not a good idea, because it just slightly complicates things such as DB recovery, because you always have to specify the db-path manually. I wouldn't recommend doing that.

Edit:

the error message you're getting is "Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied". The directory you created doesn't seem to have the correct permissions and ownership -- it needs to be writable by the user who runs the MongoDB process.

To see the permissions and ownership of the '/data/db/' directory, do this: (this is what the permissions and ownership should look like)

$ ls -ld /data/db/
drwxr-xr-x 4 mongod mongod 4096 Oct 26 10:31 /data/db/

The left side 'drwxr-xr-x' shows the permissions for the User, Group, and Others. 'mongod mongod' shows who owns the directory, and which group that directory belongs to. Both are called 'mongod' in this case.

If your '/data/db' directory doesn't have the permissions and ownership above, do this:

First check what user and group your mongo user has:

# grep mongo /etc/passwd
mongod:x:498:496:mongod:/var/lib/mongo:/bin/false

You should have an entry for mongod in /etc/passwd , as it's a daemon.

sudo chmod 0755 /data/db
sudo chown -R 498:496 /data/db    # using the user-id , group-id

You can also use the user-name and group-name, as follows: (they can be found in /etc/passwd and /etc/group )

sudo chown -R mongod:mongod /data/db 

that should make it work..

In the comments below, some people used this:

sudo chown -R `id -u` /data/db
sudo chmod -R go+w /data/db

or

sudo chown -R $USER /data/db 
sudo chmod -R go+w /data/db

The disadvantage is that $USER is an account which has a login shell. Daemons should ideally not have a shell for security reasons, that's why you see /bin/false in the grep of the password file above.

Check here to better understand the meaning of the directory permissions:

I have been thinking about this issue recently. There really doesn't seem to be any restriction on use of META-INF. There are certain strictures, of course, about the necessity of putting the manifest there, but there don't appear to be any prohibitions about putting other stuff there.

Why is this the case?

The cxf case may be legit. Here's another place where this non-standard is recommended to get around a nasty bug in JBoss-ws that prevents server-side validation against the schema of a wsdl.

http://community.jboss.org/message/570377#570377

But there really don't seem to be any standards, any thou-shalt-nots. Usually these things are very rigorously defined, but for some reason, it seems there are no standards here. Odd. It seems like META-INF has become a catchall place for any needed configuration that can't easily be handled some other way.

Wrap the text in a span and set visibility:hidden; Visibility hidden will hide the element but it will still take up the same space on the page (conversely display: none removes it from the page as well).

# To sort the list in place...
ut.sort(key=lambda x: x.count, reverse=True)

# To return a new list, use the sorted() built-in function...

More on sorting by keys.

if you are using the less source, there should be a variable for the navbar height in the variables.less file. If you are not using the source, then you can customize it using the customize utilty that bootstrap's site provides. And then you can downloaded it and include it in your project. The variable you are looking for is: @navbar-height

You can also use

Cells.CurrentRegion

to give you a range representing the bounds of your data on the current active sheet

Msdn says on the topic

Returns a Range object that represents the current region. The current region is a range bounded by any combination of blank rows and blank columns. Read-only.

Then you can determine the column count via

Cells.CurrentRegion.Columns.Count

and the row count via

Cells.CurrentRegion.Rows.Count

With introduction of React hooks the state management (including forms state) became very simple and, in my opinion, way more understandable and predictable comparing with magic of other frameworks. For example:

const MyComponent = () => {
    const [value, setValue] = React.useState('some initial value');
    return <input value={value} onChange={e => setValue(e.target.value)} />;
}

This one-way flow makes it trivial to understand how the data is updated and when rendering happens. Simple but powerful to do any complex stuff in predictable and clear way. In this case, do "two-way" form state binding.

The example uses the primitive string value. Complex state management, eg. objects, arrays, nested data, can be managed this way too, but it is easier with help of libraries, like Hookstate (Disclaimer: I am the author of this library). Here is the example of complex state management.

When a form grows, there is an issue with rendering performance: form state is changed (so rerendering is needed) on every keystroke on any form field. This issue is also addressed by Hookstate. Here is the example of the form with 5000 fields: the state is updated on every keystore and there is no performance lag at all.

In Windows-Pycharm: If File Location|Path contains any string like \t then need to escape that with additional \ like \\t

I would suggest having a look at Alex Shevchuk's tutorial. He explains "major upgrade" through WiX with a good hands-on example at From MSI to WiX, Part 8 - Major Upgrade.

Try like this.

You must give a function as value to onClick()

You button:

<button type="button" onClick={ refreshPage }> <span>Reload</span> </button> 

refreshPage function:

function refreshPage(){ 
    window.location.reload(); 
}

This will center the canvas horizontally:

#canvas-container {
   width: 100%;
   text-align:center;
}

canvas {
   display: inline;
}

HTML:

<div id="canvas-container">
   <canvas>Your browser doesn't support canvas</canvas>
</div>

One situation where it is quite useful to be able to handle the x-button click event is when you are using a Form that is an MDI container. The reason is that the closeing and closed events are raised first with children and lastly with the parent. So in one scenario a user clicks the x-button to close the application and the MDI parent asks for a confirmation to proceed. In case he decides to not close the application but carry on whatever he is doing the children will already have processed the closing event potentially lost information/work whatever. One solution is to intercept the WM_CLOSE message from the Windows message loop in your main application form (i.e. which closed, terminates the application) like so:

    protected override void WndProc(ref Message m)
    {
        if (m.Msg == 0x0010) // WM_CLOSE
        {
            // If we don't want to close this window 
            if (ShowConfirmation("Are you sure?") != DialogResult.Yes) return;
        }

        base.WndProc(ref m);
    }

After gone throug the various post, this worked fine for me doing on IntelliJ Idea:

java -cp "./lib/*;Path to your test.class"  org.testng.TestNG testng.xml

Here is my directory structure:

/lib
  -- all jar including testng.jar
/out
  --/production/Example1/test.class
/src
 -- test.java
testing.xml

So execute by this command:

java -cp "./lib/*;C:\Users\xyz\IdeaProjects\Example1\out\production\Example1" org.testng.TestNG testng.xml

My project directory Example1 is in the path:

C:\Users\xyz\IdeaProjects\

Since it isn't practical to put code in a comment, in response to your comment in Eric's answer that it's not working for you...

I just ran the following on a SQL 2005 box (sorry, no 2000 handy) with default settings and it worked without error:

CREATE TABLE dbo.Test_Identity_Insert
(
    id  INT IDENTITY NOT NULL,
    my_string   VARCHAR(20) NOT NULL,
    CONSTRAINT PK_Test_Identity_Insert PRIMARY KEY CLUSTERED (id)
)
GO

INSERT INTO dbo.Test_Identity_Insert VALUES ('test')
GO

SELECT * FROM dbo.Test_Identity_Insert
GO

Are you perhaps sending the ID value over in your values list? I don't think that you can make it ignore the column if you actually pass a value for it. For example, if your table has 6 columns and you want to ignore the IDENTITY column you can only pass 5 values.

Javascript Function

function AddToCart(id) {
 $.ajax({
   url: '@Url.Action("AddToCart", "ControllerName")',
   type: 'GET',
   dataType: 'json',
   cache: false,
   data: { 'id': id },
   success: function (results) {
        alert(results)
   },
   error: function () {
    alert('Error occured');
   }
   });
   }

Controller Method to call

[HttpGet]
  public JsonResult AddToCart(string id)
  {
    string newId = id;
     return Json(newId, JsonRequestBehavior.AllowGet);
  }

You just need another layer in your php array:

$post_data = array(
  'item' => array(
    'item_type_id' => $item_type,
    'string_key' => $string_key,
    'string_value' => $string_value,
    'string_extra' => $string_extra,
    'is_public' => $public,
   'is_public_for_contacts' => $public_contacts
  )
);

echo json_encode($post_data);

What you can do is the following:

.max-lines {_x000D_
  display: block;/* or inline-block */_x000D_
  text-overflow: ellipsis;_x000D_
  word-wrap: break-word;_x000D_
  overflow: hidden;_x000D_
  max-height: 3.6em;_x000D_
  line-height: 1.8em;_x000D_
}

<p class="max-lines">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vitae leo dapibus, accumsan lorem eleifend, pharetra quam. Quisque vestibulum commodo justo, eleifend mollis enim blandit eu. Aenean hendrerit nisl et elit maximus finibus. Suspendisse scelerisque consectetur nisl mollis scelerisque.</p>

where max-height: = line-height: × <number-of-lines> in em.

I think your date data should look like 2013-08-14.

<?php
 $yrdata= strtotime('2013-08-14');
    echo date('M-Y', $yrdata);
 ?>
// Output is Aug-2013

This has always worked for me:

SET CurrentDir="%~dp0"

ECHO The current file path this bat file is executing in is the following:

ECHO %CurrentDir%

Pause

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

In some shells like fish you can use the ** globbing to do that:

svn add **

If the number of fields in the CSV is constant then you could do something like this:

select a[1], a[2], a[3], a[4]
from (
    select regexp_split_to_array('a,b,c,d', ',')
) as dt(a)

For example:

=> select a[1], a[2], a[3], a[4] from (select regexp_split_to_array('a,b,c,d', ',')) as dt(a);
 a | a | a | a 
---+---+---+---
 a | b | c | d
(1 row)

If the number of fields in the CSV is not constant then you could get the maximum number of fields with something like this:

select max(array_length(regexp_split_to_array(csv, ','), 1))
from your_table

and then build the appropriate a[1], a[2], ..., a[M] column list for your query. So if the above gave you a max of 6, you'd use this:

select a[1], a[2], a[3], a[4], a[5], a[6]
from (
    select regexp_split_to_array(csv, ',')
    from your_table
) as dt(a)

You could combine those two queries into a function if you wanted.

For example, give this data (that's a NULL in the last row):

=> select * from csvs;
     csv     
-------------
 1,2,3
 1,2,3,4
 1,2,3,4,5,6

(4 rows)

=> select max(array_length(regexp_split_to_array(csv, ','), 1)) from csvs;
 max 
-----
   6
(1 row)

=> select a[1], a[2], a[3], a[4], a[5], a[6] from (select regexp_split_to_array(csv, ',') from csvs) as dt(a);
 a | a | a | a | a | a 
---+---+---+---+---+---
 1 | 2 | 3 |   |   | 
 1 | 2 | 3 | 4 |   | 
 1 | 2 | 3 | 4 | 5 | 6
   |   |   |   |   | 
(4 rows)

Since your delimiter is a simple fixed string, you could also use string_to_array instead of regexp_split_to_array:

select ...
from (
    select string_to_array(csv, ',')
    from csvs
) as dt(a);

Thanks to Michael for the reminder about this function.

You really should redesign your database schema to avoid the CSV column if at all possible. You should be using an array column or a separate table instead.

How about using a substring with IN.

select * from tablename where substring(column,1,4) IN ('M510','M615','M515','M612')

You can also try dism /online /Enable-Feature /FeatureName:TelnetClient

Run this command with "Run as an administrator"

Reference

An alternative to services is to use the value store.

In the base of my app I added this

var agentApp = angular.module('rbAgent', ['ui.router', 'rbApp.tryGoal', 'rbApp.tryGoal.service', 'ui.bootstrap']);

agentApp.value('agentMemory',
    {
        contextId: '',
        sessionId: ''
    }
);
...

And then in my controller I just reference the value store. I don't think it holds thing if the user closes the browser.

angular.module('rbAgent')
.controller('AgentGoalListController', ['agentMemory', '$scope', '$rootScope', 'config', '$state', function(agentMemory, $scope, $rootScope, config, $state){

$scope.config = config;
$scope.contextId = agentMemory.contextId;
...

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

You're looking for JSON.stringify().

To understand circular dependencies, you need to remember that Python is essentially a scripting language. Execution of statements outside methods occurs at compile time. Import statements are executed just like method calls, and to understand them you should think about them like method calls.

When you do an import, what happens depends on whether the file you are importing already exists in the module table. If it does, Python uses whatever is currently in the symbol table. If not, Python begins reading the module file, compiling/executing/importing whatever it finds there. Symbols referenced at compile time are found or not, depending on whether they have been seen, or are yet to be seen by the compiler.

Imagine you have two source files:

File X.py

def X1:
    return "x1"

from Y import Y2

def X2:
    return "x2"

File Y.py

def Y1:
    return "y1"

from X import X1

def Y2:
    return "y2"

Now suppose you compile file X.py. The compiler begins by defining the method X1, and then hits the import statement in X.py. This causes the compiler to pause compilation of X.py and begin compiling Y.py. Shortly thereafter the compiler hits the import statement in Y.py. Since X.py is already in the module table, Python uses the existing incomplete X.py symbol table to satisfy any references requested. Any symbols appearing before the import statement in X.py are now in the symbol table, but any symbols after are not. Since X1 now appears before the import statement, it is successfully imported. Python then resumes compiling Y.py. In doing so it defines Y2 and finishes compiling Y.py. It then resumes compilation of X.py, and finds Y2 in the Y.py symbol table. Compilation eventually completes w/o error.

Something very different happens if you attempt to compile Y.py from the command line. While compiling Y.py, the compiler hits the import statement before it defines Y2. Then it starts compiling X.py. Soon it hits the import statement in X.py that requires Y2. But Y2 is undefined, so the compile fails.

Please note that if you modify X.py to import Y1, the compile will always succeed, no matter which file you compile. However if you modify file Y.py to import symbol X2, neither file will compile.

Any time when module X, or any module imported by X might import the current module, do NOT use:

from X import Y

Any time you think there may be a circular import you should also avoid compile time references to variables in other modules. Consider the innocent looking code:

import X
z = X.Y

Suppose module X imports this module before this module imports X. Further suppose Y is defined in X after the import statement. Then Y will not be defined when this module is imported, and you will get a compile error. If this module imports Y first, you can get away with it. But when one of your co-workers innocently changes the order of definitions in a third module, the code will break.

In some cases you can resolve circular dependencies by moving an import statement down below symbol definitions needed by other modules. In the examples above, definitions before the import statement never fail. Definitions after the import statement sometimes fail, depending on the order of compilation. You can even put import statements at the end of a file, so long as none of the imported symbols are needed at compile time.

Note that moving import statements down in a module obscures what you are doing. Compensate for this with a comment at the top of your module something like the following:

#import X   (actual import moved down to avoid circular dependency)

In general this is a bad practice, but sometimes it is difficult to avoid.

For example, to set the background color to orange:

<meta name="theme-color" content="#db5945">

In addition, Chrome will show beautiful high-res favicons when they’re provided. Chrome for Android picks the highest res icon that you provide, and we recommend providing a 192×192px PNG file. For example:

<link rel="icon" sizes="192x192" href="nice-highres.png">

select * from your_table where MONTH(mont_year) = MONTH(NOW()) and YEAR(mont_year) = YEAR(NOW());

Note: (month_year) means your column that contain date format. I think that will solve your problem. Let me know if that query doesn't works.

the std::map is based on a red black tree. You can also use other containers to help you implement your own types of trees.

I was surprised that nobody mentioned this:

RedirectMatch ^/$ /store/

Basically, it redirects the root and only the root URL. The answer originated from this link

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

You can create a list of lists

   public class MultiDimList: List<List<string>> {  }

or a Dictionary of key-accessible Lists

   public class MultiDimDictList: Dictionary<string, List<int>>  { }
   MultiDimDictList myDicList = new MultiDimDictList ();
   myDicList.Add("ages", new List<int>()); 
   myDicList.Add("Salaries", new List<int>()); 
   myDicList.Add("AccountIds", new List<int>()); 

Generic versions, to implement suggestion in comment from @user420667

  public class MultiDimList<T>: List<List<T>> {  }

and for the dictionary,

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  { }

  // to use it, in client code
   var myDicList = new MultiDimDictList<string, int> ();
   myDicList.Add("ages", new List<T>()); 
   myDicList["ages"].Add(23);
   myDicList["ages"].Add(32);
   myDicList["ages"].Add(18);

   myDicList.Add("salaries", new List<T>());
   myDicList["salaries"].Add(80000);
   myDicList["salaries"].Add(100000);

   myDicList.Add("accountIds", new List<T>()); 
   myDicList["accountIds"].Add(321123);
   myDicList["accountIds"].Add(342653);

or, even better, ...

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  
   {
       public void Add(K key, T addObject)
       {
           if(!ContainsKey(key)) Add(key, new List<T>());
           if (!base[key].Contains(addObject)) base[key].Add(addObject);
       }           
   }


  // and to use it, in client code
    var myDicList = new MultiDimDictList<string, int> ();
    myDicList.Add("ages", 23);
    myDicList.Add("ages", 32);
    myDicList.Add("ages", 18);
    myDicList.Add("salaries", 80000);
    myDicList.Add("salaries", 110000);
    myDicList.Add("accountIds", 321123);
    myDicList.Add("accountIds", 342653);

EDIT: to include an Add() method for nested instance:

public class NestedMultiDimDictList<K, K2, T>: 
           MultiDimDictList<K, MultiDimDictList<K2, T>>: 
{
       public void Add(K key, K2 key2, T addObject)
       {
           if(!ContainsKey(key)) Add(key, 
                  new MultiDimDictList<K2, T>());
           if (!base[key].Contains(key2)) 
               base[key].Add(key2, addObject);
       }    
}

Idk anything about 16 character hex strings....

using System;
using System.Security.Cryptography;
using System.Text;

But here is mine for creating MD5 hash in one line.

string hash = BitConverter.ToString(MD5.Create().ComputeHash(Encoding.ASCII.GetBytes("THIS STRING TO MD5"))).Replace("-","");

Set universal_newlines to True, i.e.

command_stdout = Popen(['ls', '-l'], stdout=PIPE, universal_newlines=True).communicate()[0]

here is what works with the version of the program that I'm using: may work for you too.

I will just place the instruction and command that does it. class is the name of the table. you change it in the table its self with this method. not just the return on the search process.

view the table class

select * from class

change the length of the columns FacID (seen as "faci") and classnumber (seen as "classnu") to fit the whole labels.

alter table class modify facid varchar (5);

alter table class modify classnumber varchar(11);

view table again to see the difference

select * from class;

(run the command again to see the difference)

This changes the the actual table for good, but for better.

P.S. I made these instructions up as a note for the commands. This is not a test, but can help on one :)

This is not related to Flink, but I've found this issue in Flink also.

For people using Flink, you need to download Pre-bundled Hadoop and put it inside /opt/flink/lib.

Add your IP address in the hosts file.which is in the folder of C:\Windows\System32\drivers\etc. Also add IP and Domain Name of the IP address. example: aaa.bbb.ccc.ddd [email protected]

If you are checking for DBNULL, converting a SQL Datetime to a .NET DateTime should not be a problem. However, you can run into problems converting a .NET DateTime to a valid SQL DateTime.

SQL Server does not recognize dates prior to 1/1/1753. Thats the year England adopted the Gregorian Calendar. Usually checking for DateTime.MinValue is sufficient, but if you suspect that the data could have years before the 18th century, you need to make another check or use a different data type. (I often wonder what Museums use in their databases)

Checking for max date is not really necessary, SQL Server and .NET DateTime both have a max date of 12/31/9999 It may be a valid business rule but it won't cause a problem.

One more method worth to mention here:

SQLCMD -S SEVERNAME -E -Q "SELECT COLUMN FROM TABLE" -s "," -o "c:\test.csv"

NOTE: I don't see any network admin let you run powershell scripts

Performance-wise parseInt and such are much worser than other solutions, because at least require exception handling.

I've run jmh tests and have found that iterating over String using charAt and comparing chars with boundary chars is the fastest way to test if string contains only digits.

JMH testing

Tests compare performance of Character.isDigit vs Pattern.matcher().matches vs Long.parseLong vs checking char values.

These ways can produce different result for non-ascii strings and strings containing +/- signs.

Tests run in Throughput mode (greater is better) with 5 warmup iterations and 5 test iterations.

Results

Note that parseLong is almost 100 times slower than isDigit for first test load.

Updated on Feb 23, 2018

• Add two more cases - one using charAt instead of creating extra array and another using IntStream of char codes
• Add immediate break if non-digit found for looped test cases
• Return false for empty string for looped test cases

Updated on Feb 23, 2018

• Add one more test case (the fastest!) that compares char value without using stream

There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.

Rendering and Visibility

There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.

Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat attribute value to server on the markup page.

<div id="myDiv" runat="server"></div>

The decision to render the div or not can now be done in the code behind class like so:

myDiv.Visible = someConditionalBool;

If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.

Client Side Hiding

Hiding an element is done on the client side only. Meaning, it's rendered but it has a display CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server set just as I explained in the previous example.

Hiding in the Code Behind Class

To hide an element that you want rendered to the page but hidden is another simple single line of code:

myDiv.Style["display"] = "none";

If you have a need to remove the display style server side, it can be done by removing the display style, or setting it to a different value like inline or block (values described here).

myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

// then to show again
myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

// ... and to show 
myDiv.show();

Give Safe User Permission To Use Port 80

Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/

Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port - where port number > 1024.

A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:

sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``

Now, when you tell a Node application that you want it to run on port 80, it will not complain.

Firstly, application.properties in the @PropertySource should read application-test.properties if that's what the file is named (matching these things up matters):

@PropertySource("classpath:application-test.properties ")

That file should be under your /src/test/resources classpath (at the root).

I don't understand why you'd specify a dependency hard coded to a file called application-test.properties. Is that component only to be used in the test environment?

The normal thing to do is to have property files with the same name on different classpaths. You load one or the other depending on whether you are running your tests or not.

In a typically laid out application, you'd have:

src/test/resources/application.properties

and

src/main/resources/application.properties

And then inject it like this:

@PropertySource("classpath:application.properties")

The even better thing to do would be to expose that property file as a bean in your spring context and then inject that bean into any component that needs it. This way your code is not littered with references to application.properties and you can use anything you want as a source of properties. Here's an example: how to read properties file in spring project?

I had a similar situation when reading from Oracle in a Spark job. This connection reset error was caused by an incompatibility between the Oracle server and the JDBC driver used. Worth checking it.

As the message says, you have a task which threw an unhandled exception.

Turn on Break on All Exceptions (Debug, Exceptions) and rerun the program.
This will show you the original exception when it was thrown in the first place.

(comment appended): In VS2015 (or above). Select Debug > Options > Debugging > General and unselect the "Enable Just My Code" option.

there are many options that would change the height of an input box. padding, font-size, height would all do this. different combinations of these produce taller input boxes with different styles. I suggest just changing the font-size (and font-family for looks) and add some padding to make it even taller and also more appealing. I will give you an example of all three style though:

#signin input {
font-size:20px;
}

OR

#signin input {
padding:10px;
}

OR

#signin input {
height:24px;
}

This is the combination of the three that I recommend:

#signin input {
font-size:20px;font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; font-weight: 300;
padding:10px;
}

Runnable is just an interface, which provides the method run. Threads are implementations and use Runnable to call the method run().

$('element').html('<h1>TEXT TO INSERT</h1>');

or

$('element').text('TEXT TO INSERT');

C is the core language that most closely resembles and directly translates into CPU machine code. CPUs follow instructions that move, add, logically combine, compare, jump, push and pop. C does exactly this using much easier syntax. If you study the disassembly, you can learn to write C code that is just as fast and compact as assembly. It is my preferred language on 8 bit micro controllers with limited memory. If you write a large PC program in C you will get into trouble because of its limited organization. That is where object oriented programming becomes powerful. The ability of C++ and C# classes to contain data and functions together enforces organization which in turn allows more complex operability over C. C++ was essential for quick processing in the past when CPUs only had one core. I am beginning to learn C# now. Its class only structure appears to enforce a higher degree of organization than C++ which should ultimately lead to faster development and promote code sharing. C# is not interpreted like VB. It is partially compiled at development time and then further translated at run time to become more platform friendly.

All of the JAD links listed so far far seem to be broken, so I found this site. Works great (for Linux, at least)! On Ubuntu 11.10 I had to download the static one for whatever reason.

Using time.time to measure execution gives you the overall execution time of your commands including running time spent by other processes on your computer. It is the time the user notices, but is not good if you want to compare different code snippets / algorithms / functions / ...

If you want a deeper insight into profiling:

• http://wiki.python.org/moin/PythonSpeed/PerformanceTips#Profiling_Code
• How can you profile a python script?

Update: I used http://pythonhosted.org/line_profiler/ a lot during the last year and find it very helpfull and recommend to use it instead of Pythons profile module.

There are multiple rows with the same date, but the time is different. Therefore, DISTINCT start_date will not work. What you need is: cast the start_date to a DATE (so the TIME part is gone), and then do a DISTINCT:

SELECT DISTINCT CAST(start_date AS DATE) FROM table;

Depending on what database you use, the type name for DATE is different.

HTML :

<div id="myDiv">
    <form id="myForm">

You can use !, but you must have the ENABLEDELAYEDEXPANSION switch set.

setlocal ENABLEDELAYEDEXPANSION
set word=table
set str="jump over the chair"
set str=%str:chair=!word!%

I thought this is a simpler script if you want to remove all quotes

UPDATE Table_Name
SET col_name = REPLACE(col_name, '"', '')

If you are asking about actual command line makefiles then you can export a makefile, or you can call MSBuild on a solution file from the command line. What exactly do you want to do with the makefile?

You can do a search on SO for MSBuild for more details.

You can do via Page directive.

For example:

<%@ page language="java" contentType="application/json; charset=UTF-8"
    pageEncoding="UTF-8"%>

• contentType="mimeType [ ;charset=characterSet ]" | "text/html;charset=ISO-8859-1"

The MIME type and character encoding the JSP file uses for the response it sends to the client. You can use any MIME type or character set that are valid for the JSP container. The default MIME type is text/html, and the default character set is ISO-8859-1.

For interest, Phil Haack just wrote an example of this in the context of a Razor Templated Delegate (http://haacked.com/archive/2011/04/14/a-better-razor-foreach-loop.aspx)

Effectively he writes an extension method which wraps the iteration in an "IteratedItem" class (see below) allowing access to the index as well as the element during iteration.

public class IndexedItem<TModel> {
  public IndexedItem(int index, TModel item) {
    Index = index;
    Item = item;
  }

  public int Index { get; private set; }
  public TModel Item { get; private set; }
}

However, while this would be fine in a non-Razor environment if you are doing a single operation (i.e. one that could be provided as a lambda) it's not going to be a solid replacement of the for/foreach syntax in non-Razor contexts.

Starting from a byte array you can use the binary package to do the conversions.

For example if you want to read ints :

buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)

The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.

Here is the list of commands you have to run while the emulator is running, I test this solution for an avd on Android 2.2 :

adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system  
adb push su /system/xbin/su  
adb shell chmod 06755 /system  
adb shell chmod 06755 /system/xbin/su

It assumes that the su binary is located in the working directory. You can find su and superuser here : http://forum.xda-developers.com/showthread.php?t=682828. You need to run these commands each time you launch the emulator. You can write a script that launch the emulator and root it.

Question#1 - These are the only way to handle view clicks.

Question#2 -
Option#1/Option#4 - There's not much difference between option#1 and option#4. The only difference I see is in one case activity is implementing the OnClickListener, whereas, in the other case, there'd be an anonymous implementation.

Option#2 - In this method an anonymous class will be generated. This method is a bit cumborsome, as, you'd need to do it multiple times, if you have multiple buttons. For Anonymous classes, you have to be careful for handling memory leaks.

Option#3 - Though, this is a easy way. Usually, Programmers try not to use any method until they write it, and hence this method is not widely used. You'd see mostly people use Option#4. Because it is cleaner in term of code.

For Folder Copy You can Use

robocopy C:\Source D:\Destination /E

For File Copy

copy D:\Sourcefile.txt D:\backup\Destinationfile.txt /Y 

Delete file in some folder last modify date more than some day

forfiles -p "D:\FolderPath" -s -m *.[Filetype eg-->.txt] -d -[Numberof dates] -c "cmd /c del @PATH"

And you can Shedule task in windows perform this task automatically in specific time.

You can try the following variant:

result=np.array(M).flatten()

To do this:

1. open terminal

2. type in the terminal: nano ; which is a text editor available for the terminal. when you do this. something like this would appear.

3. here you can type in your C program

4. type in control(^) + x -> which means to exit.

5. save the file by typing in y to save the file

6. write the file name; e.g. helloStack.c (don't forget to add .c)

7. when this appears, type in gcc helloStack.c

8. then ./a.out: this should give you your result!!

For exe files, I suppose the differences are nearly unimportant.
But to start an exe you don't even need CALL.

When starting another batch it's a big difference,
as CALL will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.

START will create a new cmd.exe for the called batch and without /b it will open a new window.
As it's a new context, variables can't be shared.

Differences

Using start /wait <prog>
- Changes of environment variables are lost when the <prog> ends
- The caller waits until the <prog> is finished

Using call <prog>
- For exe it can be ommited, because it's equal to just starting <prog>
- For an exe-prog the caller batch waits or starts the exe asynchronous, but the behaviour depends on the exe itself.
- For batch files, the caller batch continues, when the called <batch-file> finishes, WITHOUT call the control will not return to the caller batch

Addendum:

Using CALL can change the parameters (for batch and exe files), but only when they contain carets or percent signs.

call myProg param1 param^^2 "param^3" %%path%%

Will be expanded to (from within an batch file)

myProg param1 param2 param^^3 <content of path>

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

public class FindDigitFromString 
{

    public static void main(String[] args) 
    {
        String s="  Hi How Are You 11  ";        
        String s1=s.replaceAll("[^0-9]+", "");
        //*replacing all the value of string except digit by using "[^0-9]+" regex.*
       System.out.println(s1);          
   }
}

Output: 11

bmleite has the correct answer about including the module.

If that is correct in your situation, you should also ensure that you are not redefining the modules in multiple files.

Remember:

angular.module('ModuleName', [])   // creates a module.

angular.module('ModuleName')       // gets you a pre-existing module.

So if you are extending a existing module, remember not to overwrite when trying to fetch it.

To complete the answer from Sotorios Delimanolis.

It's true that ResponseEntity gives you more flexibility but in most cases you won't need it and you'll end up with these ResponseEntity everywhere in your controller thus making it difficult to read and understand.

If you want to handle special cases like errors (Not Found, Conflict, etc.), you can add a HandlerExceptionResolver to your Spring configuration. So in your code, you just throw a specific exception (NotFoundException for instance) and decide what to do in your Handler (setting the HTTP status to 404), making the Controller code more clear.

I have same problem. It just the javascript's script loads too fast--before the HTML's element loaded. So the browser returning null, since the browser can't find where is the element you like to manipulate.

I deleted file inside svn.simple directory at below path on windows machine (Windows 7):

C:\Users\[user_name]\AppData\Roaming\Subversion\auth

Problem solved.

As Srdjan Pejic says, you can use

<%= f.submit 'name', :class => 'button' %>

or the new syntax which would be:

<%= f.submit 'name', class: 'button' %>

I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:

 [ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    ForDataset GetCCDBdata();

    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    string GetCCDBdataasXMLstring();


    //[OperationContract]
    //string GetData(int value);

    //[OperationContract]
    //CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

  [DataContract]
public class ServiceData
{
    [DataMember]
    public bool Result { get; set; }
    [DataMember]
    public string ErrorMessage { get; set; }
    [DataMember]
    public string ErrorDetails { get; set; }
}

in your service1.svc.cs you can use this in the catch block:

 catch (Exception ex)
        {
            myServiceData.Result = false;
            myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
            myServiceData.ErrorDetails = ex.ToString();
            throw new FaultException<ServiceData>(myServiceData, ex.ToString());
        }

And use this in the Client application like below code:

  ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();

            string str = obj.GetCCDBdataasXMLstring();

        }

        catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
      {
          Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
          Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
          Console.ReadLine();
      }

Just try this, it will help for sure to get the exact issue.

I'm the author of elasticsearch_loader
I wrote ESL for this exact problem.

You can download it with pip:

pip install elasticsearch-loader

And then you will be able to load json files into elasticsearch by issuing:

elasticsearch_loader --index incidents --type incident json file1.json file2.json

This is working as documented. Any paths specified in PYTHONPATH are documented as normally coming after the working directory but before the standard interpreter-supplied paths. sys.path.append() appends to the existing path. See here and here. If you want a particular directory to come first, simply insert it at the head of sys.path:

import sys
sys.path.insert(0,'/path/to/mod_directory')

That said, there are usually better ways to manage imports than either using PYTHONPATH or manipulating sys.path directly. See, for example, the answers to this question.

Specify foreign key for the details tables which references to the primary key of master and set Delete rule = Cascade .

Now when u delete a record from the master table all other details table record based on the deleting rows primary key value, will be deleted automatically.

So in that case a single delete query of master table can delete master tables data as well as child tables data.

In Ubuntu, Installing latest version of gradle solved the issue for me.

Try these steps to install the latest version,

sudo add-apt-repository ppa:cwchien/gradle

sudo apt-get update

sudo apt-get install gradle

then build using,

cordova build android or ionic cordova build android

Note: If you install gradle from ubuntu repo, it will install the old version 1.4 and will not help, so sudo apt-get install gradle alone will not help most times, if you did not add the repo ppa:cwchien/gradle earlier

Agree with redsquare however it is worth mentioning that if you have a two word property like text-align you would do this:

$("#message").css({ width: '30px', height: '10px', 'text-align': 'center'});

In Spring boot, Spring Web dependency provides an embedded Apache Tomcat web server. If you remove spring-boot-starter-web dependency in the pom.xml then it doesn't provide an embedded web server.

remove the following dependency

This is perfect code , there is no problem.. You have to check that in php script.

Edit: The answer marked as "correct" is not correct.

It's easy to do. Try this code, swapping out "ie.jpg" with whatever picture you have handy:

<!DOCTYPE HTML>
<html>
    <head>
        <script>
            var canvas;
            var context;
            var ga = 0.0;
            var timerId = 0;
            
            function init()
            {
                canvas = document.getElementById("myCanvas");
                context = canvas.getContext("2d");
                timerId = setInterval("fadeIn()", 100);
            }
            
            function fadeIn()
            {
                context.clearRect(0,0, canvas.width,canvas.height);
                context.globalAlpha = ga;
                var ie = new Image();
                ie.onload = function()
                {
                    context.drawImage(ie, 0, 0, 100, 100);
                };
                ie.src = "ie.jpg";
                
                ga = ga + 0.1;
                if (ga > 1.0)
                {
                    goingUp = false;
                    clearInterval(timerId);
                }
            }
        </script>
    </head>
    <body onload="init()">
        <canvas height="200" width="300" id="myCanvas"></canvas>
    </body>
</html>

The key is the globalAlpha property.

Tested with IE 9, FF 5, Safari 5, and Chrome 12 on Win7.

Why reinvent the wheel. Just use the STL list container.

#include <list>

// in some function, you now do...
std::list<int> mylist; // integer list

More information...

Use try_files and named location block ('@apachesite'). This will remove unnecessary regex match and if block. More efficient.

location / {
    root /path/to/root/of/static/files;
    try_files $uri $uri/ @apachesite;

    expires max;
    access_log off;
}

location @apachesite {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Update: The assumption of this config is that there doesn't exist any php script under /path/to/root/of/static/files. This is common in most modern php frameworks. In case your legacy php projects have both php scripts and static files mixed in the same folder, you may have to whitelist all of the file types you want nginx to serve.

If you want to keep reference:

Array.prototype.push.apply(destinationArray, sourceArray);

USING A VISUAL DIFF TOOL

The Default Answer (at the command line)

The top answers here correctly show how to view the cached/staged changes in the Index:

$ git diff --cached

or $ git diff --staged which is an alias.

Launching the Visual Diff Tool Instead

The default answer will spit out the diff changes at the git bash (i.e. on the command line or in the console). For those who prefer a visual representation of the staged file differences, there is a script available within git which launches a visual diff tool for each file viewed rather than showing them on the command line, called difftool:

$ git difftool --staged

This will do the same this as git diff --staged, except any time the diff tool is run (i.e. every time a file is processed by diff), it will launch the default visual diff tool (in my environment, this is kdiff3).

After the tool launches, the git diff script will pause until your visual diff tool is closed. Therefore, you will need to close each file in order to see the next one.

You Can Always Use difftool in place of diff in git commands

For all your visual diff needs, git difftool will work in place of any git diff command, including all options.

For example, to have the visual diff tool launch without asking whether to do it for each file, add the -y option (I think usually you'll want this!!):

$ git difftool -y --staged

In this case it will pull up each file in the visual diff tool, one at a time, bringing up the next one after the tool is closed.

Or to look at the diff of a particular file that is staged in the Index:

$ git difftool -y --staged <<relative path/filename>>

For all the options, see the man page:

$ git difftool --help

Setting up Visual Git Tool

To use a visual git tool other than the default, use the -t <tool> option:

$ git difftool -t <tool> <<other args>>

Or, see the difftool man page for how to configure git to use a different default visual diff tool.

Example .gitconfig entries for vscode as diff/merge tool

Part of setting up a difftool involves changing the .gitconfig file, either through git commands that change it behind the scenes, or editing it directly.

You can find your .gitconfig in your home directory,such as ~ in Unix or normally c:\users\<username> on Windows).

Or, you can open the user .gitconfig in your default Git editor with git config -e --global.

Here are example entries in my global user .gitconfig for VS Code as both diff tool and merge tool:

[diff]
    tool = vscode
    guitool = vscode
[merge]
    tool = vscode
    guitool = vscode
[mergetool]
    prompt = true
[difftool "vscode"]
    cmd = code --wait --diff \"$LOCAL\" \"$REMOTE\"
    path = c:/apps/vscode/code.exe
[mergetool "vscode"]
    cmd = code --wait \"$MERGED\"
    path = c:/apps/vscode/code.exe

Just adding my 2 cents on this topic. Felt the TrulyObservableCollection required the two other constructors as found with ObservableCollection:

public TrulyObservableCollection()
        : base()
    {
        HookupCollectionChangedEvent();
    }

    public TrulyObservableCollection(IEnumerable<T> collection)
        : base(collection)
    {
        foreach (T item in collection)
            item.PropertyChanged += ItemPropertyChanged;

        HookupCollectionChangedEvent();
    }

    public TrulyObservableCollection(List<T> list)
        : base(list)
    {
        list.ForEach(item => item.PropertyChanged += ItemPropertyChanged);

        HookupCollectionChangedEvent();
    }

    private void HookupCollectionChangedEvent()
    {
        CollectionChanged += new NotifyCollectionChangedEventHandler(TrulyObservableCollectionChanged);
    }

You can add @RequestMapping like so:

@RequestMapping("/userGrid")
public @ResponseBody GridModel getUsersForGrid(
   @RequestParam("_search") String search,
   @RequestParam String nd,
   @RequestParam int rows,
   @RequestParam int page,
   @RequestParam String sidx) 
   @RequestParam String sord) {

For me these two files I have deleted by mistake, after undo these two files and get added in my changes, I was able to commit my changes to git.

It's undesirable to have to know how to instantiate a widget when you just want to override its placeholder.

    q = forms.CharField(label='search')
    ...
    q.widget.attrs['placeholder'] = "Search"

You can use grep:

grep -o "+\S\+" in.txt | tr '\n' ','

which finds the string starting with +, followed by any string \S\+, then convert new line characters into commas. This should be pretty quick for large files.

Note the comma in your string: "1,07". DecimalFormat uses a locale-specific separator string, while Double.parseDouble() does not. As you happen to live in a country where the decimal separator is ",", you can't parse your number back.

However, you can use the same DecimalFormat to parse it back:

DecimalFormat df=new DecimalFormat("0.00");
String formate = df.format(value); 
double finalValue = (Double)df.parse(formate) ;

But you really should do this instead:

double finalValue = Math.round( value * 100.0 ) / 100.0;

Note: As has been pointed out, you should only use floating point if you don't need a precise control over accuracy. (Financial calculations being the main example of when not to use them.)

Either use loop counting down over indices:

for (NSInteger i = array.count - 1; i >= 0; --i) {

or make a copy with the objects you want to keep.

In particular, do not use a for (id object in array) loop or NSEnumerator.

Just try to run the following command manually:

C:\wamp\bin\mysql\mysql5.6.17\bin\mysqld.exe --console

It worked for me :)

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

Because the compiler knows the binding at compile time. If you invoke a method on an interface, for example, then the compiler can't know and the binding is resolved at runtime because the actual object having a method invoked on it could possible be one of several. Therefore that is runtime or dynamic binding.

Your invocation is bound to the Animal class at compile time because you've specified the type. If you passed that variable into another method somewhere else, noone would know (apart from you because you wrote it) what actual class it would be. The only clue is the declared type of Animal.

Apple sort of rearranged/repurposed the fields.

Going forward, if you look on the Info tab for your Application Target, you should use the "Bundle versions string, short" as your Version (e.g., 3.4.0) and "Bundle version" as your Build (e.g., 500 or 1A500). If you don't see them both, you can add them. Those will map to the proper Version and Build textboxes on the Summary tab; they are the same values.

When viewing the Info tab, if you right-click and select Show Raw Keys/Values, you'll see the actual names are CFBundleShortVersionString (Version) and CFBundleVersion (Build).

The Version is usually used how you appear to have been using it with Xcode 3. I'm not sure on what level you're asking about the Version/Build difference, so I'll answer it philosophically.

There are all sorts of schemes, but a popular one is:

{MajorVersion}.{MinorVersion}.{Revision}

• Major version - Major changes, redesigns, and functionality changes
• Minor version - Minor improvements, additions to functionality
• Revision - A patch number for bug-fixes

Then the Build is used separately to indicate the total number of builds for a release or for the entire product lifetime.

Many developers start the Build number at 0, and every time they build they increase the number by one, increasing forever. In my projects, I have a script that automatically increases the build number every time I build. See instructions for that below.

• Release 1.0.0 might be build 542. It took 542 builds to get to a 1.0.0 release.
• Release 1.0.1 might be build 578.
• Release 1.1.0 might be build 694.
• Release 2.0.0 might be build 949.

Other developers, including Apple, have a Build number comprised of a major version + minor version + number of builds for the release. These are the actual software version numbers, as opposed to the values used for marketing.

If you go to Xcode menu > About Xcode, you'll see the Version and Build numbers. If you hit the More Info... button you'll see a bunch of different versions. Since the More Info... button was removed in Xcode 5, this information is also available from the Software > Developer section of the System Information app, available by opening Apple menu > About This Mac > System Report....

For example, Xcode 4.2 (4C139). Marketing version 4.2 is Build major version 4, Build minor version C, and Build number 139. The next release (presumably 4.3) will likely be Build release 4D, and the Build number will start over at 0 and increment from there.

The iPhone Simulator Version/Build numbers are the same way, as are iPhones, Macs, etc.

• 3.2: (7W367a)
• 4.0: (8A400)
• 4.1: (8B117)
• 4.2: (8C134)
• 4.3: (8H7)

Update: By request, here are the steps to create a script that runs each time you build your app in Xcode to read the Build number, increment it, and write it back to the app's {App}-Info.plist file. There are optional, additional steps if you want to write your version/build numbers to your Settings.bundle/Root*.plist file(s).

This is extended from the how-to article here.

In Xcode 4.2 - 5.0:

1. Load your Xcode project.
2. In the left hand pane, click on your project at the very top of the hierarchy. This will load the project settings editor.
3. On the left-hand side of the center window pane, click on your app under the TARGETS heading. You will need to configure this setup for each project target.
4. Select the Build Phases tab.
5. • In Xcode 4, at the bottom right, click the Add Build Phase button and select Add Run Script.
   • In Xcode 5, select Editor menu > Add Build Phase > Add Run Script Build Phase.
6. Drag-and-drop the new Run Script phase to move it to just before the Copy Bundle Resources phase (when the app-info.plist file will be bundled with your app).
7. In the new Run Script phase, set Shell: /bin/bash.

8. Copy and paste the following into the script area for integer build numbers:

   buildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "$INFOPLIST_FILE")
   buildNumber=$(($buildNumber + 1))
   /usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
   

   As @Bdebeez pointed out, the Apple Generic Versioning Tool (agvtool) is also available. If you prefer to use it instead, then there are a couple things to change first:

   • Select the Build Settings tab.
   • Under the Versioning section, set the Current Project Version to the initial build number you want to use, e.g., 1.
   • Back on the Build Phases tab, drag-and-drop your Run Script phase after the Copy Bundle Resources phase to avoid a race condition when trying to both build and update the source file that includes your build number.

   Note that with the agvtool method you may still periodically get failed/canceled builds with no errors. For this reason, I don't recommend using agvtool with this script.

   Nevertheless, in your Run Script phase, you can use the following script:

   "${DEVELOPER_BIN_DIR}/agvtool" next-version -all
   

   The next-version argument increments the build number (bump is also an alias for the same thing), and -all updates Info.plist with the new build number.

9. And if you have a Settings bundle where you show the Version and Build, you can add the following to the end of the script to update the version and build. Note: Change the PreferenceSpecifiers values to match your settings. PreferenceSpecifiers:2 means look at the item at index 2 under the PreferenceSpecifiers array in your plist file, so for a 0-based index, that's the 3rd preference setting in the array.

   productVersion=$(/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "$INFOPLIST_FILE")
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root.plist
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root.plist
   

   If you're using agvtool instead of reading the Info.plist directly, you can add the following to your script instead:

   buildNumber=$("${DEVELOPER_BIN_DIR}/agvtool" what-version -terse)
   productVersion=$("${DEVELOPER_BIN_DIR}/agvtool" what-marketing-version -terse1)
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root.plist
   /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root.plist
   

10. And if you have a universal app for iPad & iPhone, then you can also set the settings for the iPhone file:

    /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:2:DefaultValue $buildNumber" Settings.bundle/Root~iphone.plist    
    /usr/libexec/PlistBuddy -c "Set PreferenceSpecifiers:1:DefaultValue $productVersion" Settings.bundle/Root~iphone.plist
    

Here's another simple solution. The following code will return everything before the '|' character:

if (path.Contains('|'))
   path = path.Split('|')[0];

In fact, you could have as many separators as you want, but assuming you only have one separation character, here is how you would get everything after the '|':

if (path.Contains('|'))
   path = path.Split('|')[1];

(All I changed in the second piece of code was the index of the array.)

You have to go to the /etc/nginx/sites-enabled/ and if this is the default configuration, then there should be a file by name: default.

Edit that file by defining your desired port; in the snippet below, we are serving the Nginx instance on port 81.

server {
    listen 81;
}

To start the server, run the command line below;

sudo service nginx start

You may now access your application on port 81 (for localhost, http://localhost:81).

What worked for me was using the $setSubmitted function, which first shows up in the angular docs in version 1.3.20.

In the click event where I wanted to trigger the validation, I did the following:

vm.triggerSubmit = function() {
    vm.homeForm.$setSubmitted();
    ...
}

That was all it took for me. According to the docs it "Sets the form to its submitted state." It's mentioned here.

You can use this npm package. It handles everything and has options for static and conditional classes based on a variable or a function.

// Support for string arguments
getClassNames('class1', 'class2');

// support for Object
getClassNames({class1: true, class2 : false});

// support for all type of data
getClassNames('class1', 'class2', ['class3', 'class4'], { 
    class5 : function() { return false; },
    class6 : function() { return true; }
});

<div className={getClassNames({class1: true, class2 : false})} />

I've been working on something similar and after a few tries and fails came up with this:

Example: STRING-TO-TEST-ON = 'ab,cd,ef,gh'

I wanted to extract everything after the last occurrence of "," (comma) from the string... resulting in "gh".

My query is:

SELECT SUBSTR('ab,cd,ef,gh' FROM (LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1)) AS `wantedString`

Now let me try and explain what I did ...

1. I had to find the position of the last "," from the string and to calculate the wantedString length, using LOCATE(",",REVERSE('ab,cd,ef,gh'))-1 by reversing the initial string I actually had to find the first occurrence of the "," in the string ... which wasn't hard to do ... and then -1 to actually find the string length without the ",".

2. calculate the position of my wantedString by subtracting the string length I've calculated at 1st step from the initial string length:

   LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1

I have (+1) because I actually need the string position after the last "," .. and not containing the ",". Hope it makes sense.

3. all it remain to do is running a SUBSTR on my initial string FROM the calculated position.

I haven't tested the query on large strings so I do not know how slow it is. So if someone actually tests it on a large string I would very happy to know the results.

You can use InlineComparer

public class InlineComparer<T> : IEqualityComparer<T>
{
    //private readonly Func<T, T, bool> equalsMethod;
    //private readonly Func<T, int> getHashCodeMethod;
    public Func<T, T, bool> EqualsMethod { get; private set; }
    public Func<T, int> GetHashCodeMethod { get; private set; }

    public InlineComparer(Func<T, T, bool> equals, Func<T, int> hashCode)
    {
        if (equals == null) throw new ArgumentNullException("equals", "Equals parameter is required for all InlineComparer instances");
        EqualsMethod = equals;
        GetHashCodeMethod = hashCode;
    }

    public bool Equals(T x, T y)
    {
        return EqualsMethod(x, y);
    }

    public int GetHashCode(T obj)
    {
        if (GetHashCodeMethod == null) return obj.GetHashCode();
        return GetHashCodeMethod(obj);
    }
}

Usage sample:

  var comparer = new InlineComparer<DetalleLog>((i1, i2) => i1.PeticionEV == i2.PeticionEV && i1.Etiqueta == i2.Etiqueta, i => i.PeticionEV.GetHashCode() + i.Etiqueta.GetHashCode());
  var peticionesEV = listaLogs.Distinct(comparer).ToList();
  Assert.IsNotNull(peticionesEV);
  Assert.AreNotEqual(0, peticionesEV.Count);

Can I specify my explicit type comparator inline?

Most likely the problem lies outside the code you are showing us here. You are trying to update an object that is not associated with the current session. If it is not the Invoice, then maybe it is an InvoiceItem that has already been persisted, obtained from the db, kept alive in some sort of session and then you try to persist it on a new session. This is not possible. As a general rule, never keep your persisted objects alive across sessions.

The solution will ie in obtaining the whole object graph from the same session you are trying to persist it with. In a web environment this would mean:

• Obtain the session
• Fetch the objects you need to update or add associations to. Preferabley by their primary key
• Alter what is needed
• Save/update/evict/delete what you want
• Close/commit your session/transaction

If you keep having issues post some of the code that is calling your service.

How about this:-

var regularExpression = /^(?=.*[0-9])(?=.*[!@#$%^&*])[a-zA-Z0-9!@#$%^&*]{6,}$/;

It will allow a minimum of 6 characters including numbers, alphabets, and special characters

function array_not_unique( $a = array() )
{
  return array_diff_key( $a , array_unique( $a ) );
}

When converting an ASP.Net webform prototype to a MVC site I got these errors:

TypeError: $(...).accordion is not a function
$("#accordion").accordion(

$('#dialog').dialog({
TypeError: $(...).dialog is not a function

It worked fine in the webforms. The problem/solution was this line in the _Layout.cshtml

@Scripts.Render("~/bundles/jquery")

Comment it out to see if the errors go away. Then fix it in the BundlesConfig:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));

Why dont you use?:

string[] ssizes = myStr.Split(' ', '\t');

You can add git path to environment variables

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`

AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)

I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).

Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.

The test slice provided in Spring Boot 1.4 brought feature oriented test capabilities.

For example,

@JsonTest provides a simple Jackson environment to test the json serialization and deserialization.

@WebMvcTest provides a mock web environment, it can specify the controller class for test and inject the MockMvc in the test.

@WebMvcTest(PostController.class)
public class PostControllerMvcTest{

    @Inject MockMvc mockMvc;

}

@DataJpaTest will prepare an embedded database and provides basic JPA environment for the test.

@RestClientTest provides REST client environment for the test, esp the RestTemplateBuilder etc.

These annotations are not composed with SpringBootTest, they are combined with a series of AutoconfigureXXX and a @TypeExcludesFilter annotations.

Have a look at @DataJpaTest.

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@BootstrapWith(SpringBootTestContextBootstrapper.class)
@OverrideAutoConfiguration(enabled = false)
@TypeExcludeFilters(DataJpaTypeExcludeFilter.class)
@Transactional
@AutoConfigureCache
@AutoConfigureDataJpa
@AutoConfigureTestDatabase
@AutoConfigureTestEntityManager
@ImportAutoConfiguration
public @interface DataJpaTest {}

You can add your @AutoconfigureXXX annotation to override the default config.

@AutoConfigureTestDatabase(replace=NONE)
@DataJpaTest
public class TestClass{
}

Let's have a look at your problem,

1. Do not mix @DataJpaTest and @SpringBootTest, as said above @DataJpaTest will build the configuration in its own way(eg. by default, it will try to prepare an embedded H2 instead) from the application configuration inheritance. @DataJpaTest is designated for test slice.
2. If you want to customize the configuration of @DataJpaTest, please read this official blog entry from Spring.io for this topic,(a little tedious).
3. Split the configurations in Application into smaller configurations by features, such as WebConfig, DataJpaConfig etc. A full featured configuration(mixed web, data, security etc) also caused your test slice based tests to be failed. Check the test samples in my sample.

Just for those new to iOS buddies (like me) who decided to have multiple cells and in a different xib file, the solution is not to have identifier but to do this:

let cell = Bundle.main.loadNibNamed("newsDetails", owner: self, options: nil)?.first as! newsDetailsTableViewCell

here newsDetails is xib file name.

make sure you are in the correct directory

rm -rf *

These might resolve the issue(It did for me). In IIS Express change the project property values, "Anonymous Authentication" and "Windows Authentication". To do this, when project is selected, press F4 and then change these properties.

In case you are deploying it on IIS locally, make sure local machines "Windows Authentication" feature is enabled and "Anonymous Authentication" is disabled.

I'm implementing it in Play Framework and for me it worked like this:

1) Notice that I used data-rule-equalTo in input tag for the id inputPassword1. The code section of userform in my Modal:

<div class="form-group">
    <label for="pass1">@Messages("authentication.password")</label>
    <input class="form-control required" id="inputPassword1" placeholder="@Messages("authentication.password")" type="password" name="password" maxlength=10 minlength=5>
</div>
<div class="form-group">
    <label for="pass2">@Messages("authentication.password2")</label>
    <input class="form-control required" data-rule-equalTo="#inputPassword1" id="inputPassword2" placeholder="@Messages("authentication.password")" type="password" name="password2">
</div>

2)Since I used validator within a Modal

$(document).on("click", ".createUserModal", function () {
       $(this).find('#userform').validate({
           rules: {
               firstName: "required",
               lastName: "required",
               nationalId: {
                   required: true,
                   digits:true
               },
               email: {
                   required: true,
                   email: true
               },
               optradio: "required",
               password :{
                   required: true,
                   minlength: 5
               },
               password2: {
                   required: true
               }
           },
           highlight: function (element) {
               $(element).parent().addClass('error')
           },
           unhighlight: function (element) {
               $(element).parent().removeClass('error')
           },
           onsubmit: true
       });

   });

To delete a job which has not yet run, you need the atrm command. You can use atq command to get its number in the at list.

To kill a job which has already started to run, you'll need to grep for it using:

ps -eaf | grep <command name>

and then use kill to stop it.

A quicker way to do this on most systems is:

pkill <command name>

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

This is all I know how to do though sorry.

#!/usr/local/bin/python2.7

counter=0
ipcounter=0
tcpcounter=0

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

    counter+=1
    eth=dpkt.ethernet.Ethernet(pkt) 
    if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
       continue

    ip=eth.data
    ipcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_TCP: 
       tcpcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_UDP:
       udpcounter+=1

print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter

This is round robin DNS. This is a quite simple solution for load balancing. Usually DNS servers rotate/shuffle the DNS records for each incoming DNS request. Unfortunately it's not a real solution for fail-over. If one of the servers fail, some visitors will still be directed to this failed server.

To expand a little on the other answers:

In the line:

def wrapper(func, *args):

The * next to args means "take the rest of the parameters given and put them in a list called args".

In the line:

    func(*args)

The * next to args here means "take this list called args and 'unwrap' it into the rest of the parameters.

So you can do the following:

def wrapper1(func, *args): # with star
    func(*args)

def wrapper2(func, args): # without star
    func(*args)

def func2(x, y, z):
    print x+y+z

wrapper1(func2, 1, 2, 3)
wrapper2(func2, [1, 2, 3])

In wrapper2, the list is passed explicitly, but in both wrappers args contains the list [1,2,3].

To stop executing java code just use this command:

    System.exit(1);

After this command java stops immediately!

for example:

    int i = 5;
    if (i == 5) {
       System.out.println("All is fine...java programm executes without problem");
    } else {
       System.out.println("ERROR occured :::: java programm has stopped!!!");
       System.exit(1);
    }

To find all valid address list this is the code I have used

public static IEnumerable<string> GetAddresses()
{
      var host = Dns.GetHostEntry(Dns.GetHostName());
      return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}

In order to build a more-or-less reliable list of applications that appear in the "Programs and Feautres" in the Control Panel, you have to consider that not all applications were installed using MSI. WMI only provides the ones installed with MSI.

Here is a short summary of what I've found out:

MSI applications always have a Product Code (GUID) subkey under HKLM\...\Uninstall and/or under HKLM\...\Installer\UserData\S-1-5-18\Products. In addition, they may have a key that looks like HKLM\...\Uninstall\NotAGuid.

Non-MSI applications do not have a product code, and therefore have keys like HKLM\...\Uninstall\NotAGuid or HKCU\...\Uninstall\NotAGuid.

Just as a future reference, if you already have a Maven project all you need to do is doing a gradle init in your project directory which will generates build.gradle and other dependencies, then do a gradle build in the same directory.

Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.

Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

This bash function has the minimal dependency(only sort and bash):

shuf() {
while read -r x;do
    echo $RANDOM$'\x1f'$x
done | sort |
while IFS=$'\x1f' read -r x y;do
    echo $y
done
}

Just use withDayOfMonth, and lengthOfMonth():

LocalDate initial = LocalDate.of(2014, 2, 13);
LocalDate start = initial.withDayOfMonth(1);
LocalDate end = initial.withDayOfMonth(initial.lengthOfMonth());

I think this is a simple and easy way to compare two lists element by element

x=[1,2,3,5,4,8,7,11,12,45,96,25]
y=[2,4,5,6,8,7,88,9,6,55,44,23]

tmp = []


for i in range(len(x)) and range(len(y)):
    if x[i]>y[i]:
        tmp.append(1)
    else:
        tmp.append(0)
print(tmp)

Such problem might occur when you use surfire plugin 3.x.x+ with JUnit5 and by mistake annotate the test class with @Test annotation from JUnit4.

Use: org.junit.jupiter.api.Test (JUnit5) instead of org.junit.Test (Junit4)

NOTE: this might be hard to notice as the IDE might run this wihout problems just as JUnit4 test.

I am not exactly sure which part to blame, but here's why MemoryStream doesn't work for you:

As you write to MemoryStream, it increments it's Position property. The constructor of StreamContent takes into account the stream's current Position. So if you write to the stream, then pass it to StreamContent, the response will start from the nothingness at the end of the stream.

There's two ways to properly fix this:

1) construct content, write to stream

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    // ...
    // stream.Write(...);
    // ...
    return response;
}

2) write to stream, reset position, construct content

[HttpGet]
public HttpResponseMessage Test()
{
    var stream = new MemoryStream();
    // ...
    // stream.Write(...);
    // ...
    stream.Position = 0;

    var response = Request.CreateResponse(HttpStatusCode.OK);
    response.Content = new StreamContent(stream);
    return response;
}

2) looks a little better if you have a fresh Stream, 1) is simpler if your stream does not start at 0

You got the order wrong. The if should be after the for (unless it is in an if-else ternary operator)

[y for y in a if y not in b]

This would work however:

[y if y not in b else other_value for y in a]

For reference using the [EnableCors()] approach will not work if you intercept the Message Pipeline using a DelegatingHandler. In my case was checking for an Authorization header in the request and handling it accordingly before the routing was even invoked, which meant my request was getting processed earlier in the pipeline so the [EnableCors()] had no effect.

In the end found an example CrossDomainHandler class (credit to shaunxu for the Gist) which handles the CORS for me in the pipeline and to use it is as simple as adding another message handler to the pipeline.

public class CrossDomainHandler : DelegatingHandler
    {
        const string Origin = "Origin";
        const string AccessControlRequestMethod = "Access-Control-Request-Method";
        const string AccessControlRequestHeaders = "Access-Control-Request-Headers";
        const string AccessControlAllowOrigin = "Access-Control-Allow-Origin";
        const string AccessControlAllowMethods = "Access-Control-Allow-Methods";
        const string AccessControlAllowHeaders = "Access-Control-Allow-Headers";

        protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            bool isCorsRequest = request.Headers.Contains(Origin);
            bool isPreflightRequest = request.Method == HttpMethod.Options;
            if (isCorsRequest)
            {
                if (isPreflightRequest)
                {
                    return Task.Factory.StartNew(() =>
                    {
                        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
                        response.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());

                        string accessControlRequestMethod = request.Headers.GetValues(AccessControlRequestMethod).FirstOrDefault();
                        if (accessControlRequestMethod != null)
                        {
                            response.Headers.Add(AccessControlAllowMethods, accessControlRequestMethod);
                        }

                        string requestedHeaders = string.Join(", ", request.Headers.GetValues(AccessControlRequestHeaders));
                        if (!string.IsNullOrEmpty(requestedHeaders))
                        {
                            response.Headers.Add(AccessControlAllowHeaders, requestedHeaders);
                        }

                        return response;
                    }, cancellationToken);
                }
                else
                {
                    return base.SendAsync(request, cancellationToken).ContinueWith(t =>
                    {
                        HttpResponseMessage resp = t.Result;
                        resp.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());
                        return resp;
                    });
                }
            }
            else
            {
                return base.SendAsync(request, cancellationToken);
            }
        }
    }

To use it add it to the list of registered message handlers

config.MessageHandlers.Add(new CrossDomainHandler());

Any preflight requests by the Browser are handled and passed on, meaning I didn't need to implement an [HttpOptions] IHttpActionResult method on the Controller.

Yes you can!

As of November 2016, Microsoft now has integrated .NET Core in it's official .NET Site

Actually, this error message just says that there is some problem but no specifications of the problem. So, in my case, it was a pending pull request. I pulled the changes into my repo, and then pushed it again and it worked. Moreover, if there is an error on tortoisegit, I prefer to do the same on console. Console gives more detail error message

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :

1) insert and append methods are not specific to sys.path and as in other languages they add an item into a list or array and :
* append(item) add item to the end of the list,
* insert(n, item) inserts the item at the nth position in the list (0 at the beginning, 1 after the first element, etc ...).

2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append to add your path, you will not get your function but the predefined one.

But I think that it is better to use append and not insert to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.

Your for loop looks good.

A possible while loop to accomplish the same thing:

int sum = 0;
int i = 1;
while (i <= 100) {
    sum += i;
    i++;
}
System.out.println("The sum is " + sum);

A possible do while loop to accomplish the same thing:

int sum = 0;
int i = 1;
do {
    sum += i;
    i++;
} while (i <= 100);
System.out.println("The sum is " + sum);

The difference between the while and the do while is that, with the do while, at least one iteration is sure to occur.

From version 1.3.0 this can easily be done with $touched, which is true after the user has left the field.

<p ng-show="form.field.$touched && form.field.$invalid">Error</p>

This work for my:

log4j.logger.org.hibernate.type=trace

Also can try:

log4j.category.org.hibernate.type=trace

To submit the form when the enter key is pressed create a javascript function along these lines.

function checkSubmit(e) {
   if(e && e.keyCode == 13) {
      document.forms[0].submit();
   }
}

Then add the event to whatever scope you need eg on the div tag:

<div onKeyPress="return checkSubmit(event)"/>

This is also the default behaviour of Internet Explorer 7 anyway though (probably earlier versions as well).

Instead of using regexp_replace multiple time use (\s) as given below;

SELECT regexp_replace('TEXT','(\s)','')
FROM dual;

Here's one more approach by using SET and FOR /F

@echo off

set "var=<?xml version="1.0" encoding="utf-8" ?>"

for /f "tokens=1* delims==" %%a in ('set var') do echo %%b

and you can beautify it like:

@echo off
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
set "print{[=for /f "tokens=1* delims==" %%a in ('set " & set "]}=') do echo %%b"
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::


set "xml_line.1=<?xml version="1.0" encoding="utf-8" ?>"
set "xml_line.2=<root>"
set "xml_line.3=</root>"

%print{[% xml_line %]}%

HTML:

<ul>
  <li onclick="myfunction(this)">
    <span></span>
    <p>This Text</p>
  </li>
</ul>?

JavaScript:

function myfunction(foo) {
    var elem = foo.getElementsByTagName('p');
    var TextInsideLi = elem[0].innerHTML;
}?

Most simplest way is to use a IF(). Yes Mysql allows you to do conditional logic. IF function takes 3 params CONDITION, TRUE OUTCOME, FALSE OUTCOME.

So Logic is

if report.type = 'p' 
    amount = amount 
else 
    amount = -1*amount 

SQL

SELECT 
    id, IF(report.type = 'P', abs(amount), -1*abs(amount)) as amount
FROM  report

You may skip abs() if all no's are +ve only

As previously mentioned it is officially not possible to change the format. However it is possible to style the field, so (with a little JS help) it displays the date in a format we desire. Some of the possibilities to manipulate the date input is lost this way, but if the desire to force the format is greater, this solution might be a way. A date fields stays only like that:

<input type="date" data-date="" data-date-format="DD MMMM YYYY" value="2015-08-09">

The rest is a bit of CSS and JS: http://jsfiddle.net/g7mvaosL/

$("input").on("change", function() {_x000D_
    this.setAttribute(_x000D_
        "data-date",_x000D_
        moment(this.value, "YYYY-MM-DD")_x000D_
        .format( this.getAttribute("data-date-format") )_x000D_
    )_x000D_
}).trigger("change")

input {_x000D_
    position: relative;_x000D_
    width: 150px; height: 20px;_x000D_
    color: white;_x000D_
}_x000D_
_x000D_
input:before {_x000D_
    position: absolute;_x000D_
    top: 3px; left: 3px;_x000D_
    content: attr(data-date);_x000D_
    display: inline-block;_x000D_
    color: black;_x000D_
}_x000D_
_x000D_
input::-webkit-datetime-edit, input::-webkit-inner-spin-button, input::-webkit-clear-button {_x000D_
    display: none;_x000D_
}_x000D_
_x000D_
input::-webkit-calendar-picker-indicator {_x000D_
    position: absolute;_x000D_
    top: 3px;_x000D_
    right: 0;_x000D_
    color: black;_x000D_
    opacity: 1;_x000D_
}

<input type="date" data-date="" data-date-format="DD MMMM YYYY" value="2015-08-09">

It works nicely on Chrome for desktop, and Safari on iOS (especially desirable, since native date manipulators on touch screens are unbeatable IMHO). Didn't check for others, but don't expect to fail on any Webkit.

.service-small option {
    font-size: 14px;
    padding: 5px;

}

I think it because you used .styled-select in start of the class code.

Sometimes you want to have your GridView as simple as:

  <asp:GridView ID="grid" runat="server" />

You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.

protected void Page_Load(object sender, EventArgs e)
{
  grid.RowDataBound += grid_RowDataBound;
  // Your DB access code here...
  // grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  // grid.DataBind();
}

void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType != DataControlRowType.DataRow)
    return;
  var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
  e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}

For those using Vue CLI 3 and the webpack-simple install, Aaron's answer did work for me however I wasn't keen on adding my environment variables to my webpack.config.js as I wanted to commit it to GitHub. Instead I installed the dotenv-webpack plugin and this appears to load environment variables fine from a .env file at the root of the project without the need to prepend VUE_APP_ to the environment variables.

Need to include jquery-ui too:

<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

And if you want to pass a value from your model and want to select a radio button from the group on load based on value, than use:

Jquery:

var priority = Model.Priority; //coming for razor model in this case
var allInputIds = "#slider-vertical-" + itemIndex + " fieldset input";

$(allInputIds).val([priority]); //Select at start up

And the html:

<div id="@("slider-vertical-"+Model.Id)">
 <fieldset data-role="controlgroup" data-type="horizontal" data-mini="true">
    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("high-"+Model.Id)" value="1" checked="checked">
    <label for="@("high-"+Model.Id)" style="width:100px">@UIStrings.PriorityHighText</label>

    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("medium-"+Model.Id)" value="2">
    <label for="@("medium-"+Model.Id)" style="width:100px">@UIStrings.PriorityMediumText</label>

    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("low-"+Model.Id)" value="3">
    <label for="@("low-"+Model.Id)" style="width:100px">@UIStrings.PriorityLowText</label>
 </fieldset>
</div>

Using keySet-

id1.keySet().stream()
        .filter(x -> x == 1)
        .map(x -> id1.get(x))
        .collect(Collectors.toList())

Class1 is not in the global scope.

See below for a working example:

<?php

function __autoload($class)
{
    $parts = explode('\\', $class);
    require end($parts) . '.php';
}

use Person\Barnes\David as MyPerson;

$class = new MyPerson\Class1();

Edit (2009-12-14):

Just to clarify, my usage of "use ... as" was to simplify the example.

The alternative was the following:

$class = new Person\Barnes\David\Class1();

or

use Person\Barnes\David\Class1;

// ...

$class = new Class1();

Technically there aren't actually any "remote" things at all¹ in your Git repo, there are just local names that should correspond to the names on another, different repo. The ones named origin/whatever will initially match up with those on the repo you cloned-from:

git clone ssh://some.where.out.there/some/path/to/repo # or git://some.where...

makes a local copy of the other repo. Along the way it notes all the branches that were there, and the commits those refer-to, and sticks those into your local repo under the names refs/remotes/origin/.

Depending on how long you go before you git fetch or equivalent to update "my copy of what's some.where.out.there", they may change their branches around, create new ones, and delete some. When you do your git fetch (or git pull which is really fetch plus merge), your repo will make copies of their new work and change all the refs/remotes/origin/<name> entries as needed. It's that moment of fetching that makes everything match up (well, that, and the initial clone, and some cases of pushing too—basically whenever Git gets a chance to check—but see caveat below).

Git normally has you refer to your own refs/heads/<name> as just <name>, and the remote ones as origin/<name>, and it all just works because it's obvious which one is which. It's sometimes possible to create your own branch names that make it not obvious, but don't worry about that until it happens. :-) Just give Git the shortest name that makes it obvious, and it will go from there: origin/master is "where master was over there last time I checked", and master is "where master is over here based on what I have been doing". Run git fetch to update Git on "where master is over there" as needed.

Caveat: in versions of Git older than 1.8.4, git fetch has some modes that don't update "where master is over there" (more precisely, modes that don't update any remote-tracking branches). Running git fetch origin, or git fetch --all, or even just git fetch, does update. Running git fetch origin master doesn't. Unfortunately, this "doesn't update" mode is triggered by ordinary git pull. (This is mainly just a minor annoyance and is fixed in Git 1.8.4 and later.)

¹Well, there is one thing that is called a "remote". But that's also local! The name origin is the thing Git calls "a remote". It's basically just a short name for the URL you used when you did the clone. It's also where the origin in origin/master comes from. The name origin/master is called a remote-tracking branch, which sometimes gets shortened to "remote branch", especially in older or more informal documentation.

From the Python glossary:

It’s important to keep in mind that all packages are modules, but not all modules are packages. Or put another way, packages are just a special kind of module. Specifically, any module that contains a __path__ attribute is considered a package.

Python files with a dash in the name, like my-file.py, cannot be imported with a simple import statement. Code-wise, import my-file is the same as import my - file which will raise an exception. Such files are better characterized as scripts whereas importable files are modules.

if user3223763's answer doesn't works, you can try this:

sudo apt-get remove nodejs ^node-* nodejs-*
sudo apt-get autoremove
sudo apt-get clean
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install nodejs

Then :

curl https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | sh

After this, open a new terminal and check the npm version:

npm --version

EDIT / UPDATE :

Today the last nvm version is :

https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh

Thus the CURL command is: v0.25.4 instead of v0.13.1

curl https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh | sh

You can check https://github.com/creationix/nvm/releases to use the correct version for further upgrades
