Answers above are shown how to remove an array and here is how to pull an object from an array.

Reference: https://docs.mongodb.com/manual/reference/operator/update/pull/

db.survey.update( // select your doc in moongo
    { }, // your query, usually match by _id
    { $pull: { results: { $elemMatch: { score: 8 , item: "B" } } } }, // item(s) to match from array you want to pull/remove
    { multi: true } // set this to true if you want to remove multiple elements.
)

simple synchronous way with node:

let fs = require('fs')

let filename = "your-file.something"

let content = fs.readFileSync(process.cwd() + "/" + filename).toString()

console.log(content)

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

The question is really about scope, as the other guy put it.

In short, consider this "module":

Public Var1 As variant     'Var1 can be used in all
                           'modules, class modules and userforms of 
                           'thisworkbook and will preserve any values
                           'assigned to it until either the workbook
                           'is closed or the project is reset.

Dim Var2 As Variant        'Var2 and Var3 can be used anywhere on the
Private Var3 As Variant    ''current module and will preserve any values
                           ''they're assigned until either the workbook
                           ''is closed or the project is reset.

Sub MySub()                'Var4 can only be used within the procedure MySub
    Dim Var4 as Variant    ''and will only store values until the procedure 
End Sub                    ''ends.

Sub MyOtherSub()           'You can even declare another Var4 within a
    Dim Var4 as Variant    ''different procedure without generating an
End Sub                    ''error (only possible confusion). 

You can check out this MSDN reference for more on variable declaration and this other Stack Overflow Question for more on how variables go out of scope.

Two other quick things:

1. Be organized when using workbook level variables, so your code doesn't get confusing. Prefer Functions (with proper data types) or passing arguments ByRef.
2. If you want a variable to preserve its value between calls, you can use the Static statement.

Modifying Jonathan's great answer to avoid monkey patching:

var stringifyError = function(err, filter, space) {
  var plainObject = {};
  Object.getOwnPropertyNames(err).forEach(function(key) {
    plainObject[key] = err[key];
  });
  return JSON.stringify(plainObject, filter, space);
};

var error = new Error('testing');
error.detail = 'foo bar';

console.log(stringifyError(error, null, '\t'));

code:

a="http://www.example.com"
try:    
    print urllib.urlopen(a)
except:
    print a+"  site does not exist"

You can't define categories (Swift extensions) with new storage; any additional properties must be computed rather than stored. The syntax works for Objective C because @property in a category essentially means "I'll provide the getter and setter". In Swift, you'll need to define these yourself to get a computed property; something like:

extension String {
    public var Foo : String {
        get
        {
            return "Foo"
        }

        set
        {
            // What do you want to do here?
        }
    }
}

Should work fine. Remember, you can't store new values in the setter, only work with the existing available class state.

Note: Egg packaging has been superseded by Wheel packaging.

Same concept as a .jar file in Java, it is a .zip file with some metadata files renamed .egg, for distributing code as bundles.

Specifically: The Internal Structure of Python Eggs

A "Python egg" is a logical structure embodying the release of a specific version of a Python project, comprising its code, resources, and metadata. There are multiple formats that can be used to physically encode a Python egg, and others can be developed. However, a key principle of Python eggs is that they should be discoverable and importable. That is, it should be possible for a Python application to easily and efficiently find out what eggs are present on a system, and to ensure that the desired eggs' contents are importable.

The .egg format is well-suited to distribution and the easy uninstallation or upgrades of code, since the project is essentially self-contained within a single directory or file, unmingled with any other projects' code or resources. It also makes it possible to have multiple versions of a project simultaneously installed, such that individual programs can select the versions they wish to use.

Happened to me on node 13.7.0 and npm 6.13.6 (macOS Mojave).

I had the following as part of my errors:

found X vulnerabilities (Y moderate, Z high)
  run `npm audit fix` to fix them, or `npm audit` for details

And running the following fixed the problem:

1. $ npm audit fix

2. $ npm install

1) Almost-English style:

Test for presence using the in operator, then apply the remove method.

if thing in some_list: some_list.remove(thing)

The removemethod will remove only the first occurrence of thing, in order to remove all occurrences you can use while instead of if.

while thing in some_list: some_list.remove(thing)    

• Simple enough, probably my choice.for small lists (can't resist one-liners)

2) Duck-typed, EAFP style:

This shoot-first-ask-questions-last attitude is common in Python. Instead of testing in advance if the object is suitable, just carry out the operation and catch relevant Exceptions:

try:
    some_list.remove(thing)
except ValueError:
    pass # or scream: thing not in some_list!
except AttributeError:
    call_security("some_list not quacking like a list!")

Off course the second except clause in the example above is not only of questionable humor but totally unnecessary (the point was to illustrate duck-typing for people not familiar with the concept).

If you expect multiple occurrences of thing:

while True:
    try:
        some_list.remove(thing)
    except ValueError:
        break

• a little verbose for this specific use case, but very idiomatic in Python.
• this performs better than #1
• PEP 463 proposed a shorter syntax for try/except simple usage that would be handy here, but it was not approved.

However, with contextlib's suppress() contextmanager (introduced in python 3.4) the above code can be simplified to this:

with suppress(ValueError, AttributeError):
    some_list.remove(thing)

Again, if you expect multiple occurrences of thing:

with suppress(ValueError):
    while True:
        some_list.remove(thing)

3) Functional style:

Around 1993, Python got lambda, reduce(), filter() and map(), courtesy of a Lisp hacker who missed them and submitted working patches*. You can use filter to remove elements from the list:

is_not_thing = lambda x: x is not thing
cleaned_list = filter(is_not_thing, some_list)

There is a shortcut that may be useful for your case: if you want to filter out empty items (in fact items where bool(item) == False, like None, zero, empty strings or other empty collections), you can pass None as the first argument:

cleaned_list = filter(None, some_list)

• [update]: in Python 2.x, filter(function, iterable) used to be equivalent to [item for item in iterable if function(item)] (or [item for item in iterable if item] if the first argument is None); in Python 3.x, it is now equivalent to (item for item in iterable if function(item)). The subtle difference is that filter used to return a list, now it works like a generator expression - this is OK if you are only iterating over the cleaned list and discarding it, but if you really need a list, you have to enclose the filter() call with the list() constructor.
• *These Lispy flavored constructs are considered a little alien in Python. Around 2005, Guido was even talking about dropping filter - along with companions map and reduce (they are not gone yet but reduce was moved into the functools module, which is worth a look if you like high order functions).

4) Mathematical style:

List comprehensions became the preferred style for list manipulation in Python since introduced in version 2.0 by PEP 202. The rationale behind it is that List comprehensions provide a more concise way to create lists in situations where map() and filter() and/or nested loops would currently be used.

cleaned_list = [ x for x in some_list if x is not thing ]

Generator expressions were introduced in version 2.4 by PEP 289. A generator expression is better for situations where you don't really need (or want) to have a full list created in memory - like when you just want to iterate over the elements one at a time. If you are only iterating over the list, you can think of a generator expression as a lazy evaluated list comprehension:

for item in (x for x in some_list if x is not thing):
    do_your_thing_with(item)

• See this Python history blog post by GvR.
• This syntax is inspired by the set-builder notation in math.
• Python 3 has also set and dict comprehensions.

Notes

1. you may want to use the inequality operator != instead of is not (the difference is important)
2. for critics of methods implying a list copy: contrary to popular belief, generator expressions are not always more efficient than list comprehensions - please profile before complaining

If we're allowed to embed the class Node, I would solve the problem as I've implemented it below. hasLoop() runs in O(n) time, and takes only the space of counter. Does this seem like an appropriate solution? Or is there a way to do it without embedding Node? (Obviously, in a real implementation there would be more methods, like RemoveNode(Node n), etc.)

public class LinkedNodeList {
    Node first;
    Int count;

    LinkedNodeList(){
        first = null;
        count = 0;
    }

    LinkedNodeList(Node n){
        if (n.next != null){
            throw new error("must start with single node!");
        } else {
            first = n;
            count = 1;
        }
    }

    public void addNode(Node n){
        Node lookingAt = first;

        while(lookingAt.next != null){
            lookingAt = lookingAt.next;
        }

        lookingAt.next = n;
        count++;
    }

    public boolean hasLoop(){

        int counter = 0;
        Node lookingAt = first;

        while(lookingAt.next != null){
            counter++;
            if (count < counter){
                return false;
            } else {
               lookingAt = lookingAt.next;
            }
        }

        return true;

    }



    private class Node{
        Node next;
        ....
    }

}

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

Just in case anyone in the future has the same problem that I did:

If you use the

*
!/**/
!*.*

trick to remove binary files with no extension, make sure that ALL other gitignore lines are BELOW. Git will read from .gitignore from the top, so even though I had 'test.go' in my gitignore, it was first in the file, and became 'unignored' after

!*.*

I had copy pasted my inline js from some other .php project, inside that block of code there was some php code outputting some value, now since the variable wasn't defined in my new file, it was producing the typical php undefined warning/error, and because of that the js code was being messed up, and wasn't responding to any event, even alert("xyz"); would fail silently!! Although the erronous line was way near the end of the file, still the js would just die that too,

without any errors!!! >:(

Now one thing confusing is that debugger console/output gave no hint/error/warning whatsoever, the js was dying silently.

So try checking if you have php inline coded with the js, and see if it is outputting any error. Once removed/sorted your js should work fine.

View -> Tool Windows -> Logcat (command + 6)

Whenever you do some form of operation outside of AngularJS, such as doing an Ajax call with jQuery, or binding an event to an element like you have here you need to let AngularJS know to update itself. Here is the code change you need to do:

app.directive("remove", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.remove(element);
            scope.$apply();
        })
    };

});

app.directive("resize", function () {
    return function (scope, element, attrs) {
        element.bind ("mousedown", function () {
            scope.resize(element);
            scope.$apply();
        })
    };
});

Here is the documentation on it: https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$apply

just use a regex as a separator:

', *' - for leading spaces

' *,' - for trailing spaces

for both leading and trailing:

awk -F' *,? *' '{print $1","$2}' input.txt

iisexpress program is responsible for that.

Try setting your font from the menu and then typing

:set guifont?

This should display to you the string that Vim has set this option to. You'll need to escape any spaces.

I don't know how good of a solution this is it, but after following some of the other answer to this question without success, i resolved setting the connection user of the service MSSQLSERVER to "Local Service".

N.B: i'm using SQL Server 2017.

you can use ajax calls to call different methods without a postback

$.ajax({
    type: "POST",
     url: "@(Url.Action("Action", "Controller"))",
     data: {id: 'id', id1: 'id1' },
     contentType: "application/json; charset=utf-8",
     cache: false,
     async: true,
     success: function (result) {
        //do something
     }
});

Here's @SLaks answer, but in pure ES6 JavaScript.

var start = new Date,_x000D_
  $timer = document.querySelector('.Timer');_x000D_
_x000D_
setInterval(function(timestamp) {_x000D_
    $timer.innerText = `${timestamp - start) / 1000} Seconds`;_x000D_
}, 1000);

Put your ScrollViewer in a DockPanel and set the DockPanel MaxHeight property

[...]
<DockPanel MaxHeight="700">
  <ScrollViewer VerticalScrollBarVisibility="Auto">
   <ItemsControl ItemSource ="{Binding ...}">
     [...]
   </ItemsControl>
  </ScrollViewer>
</DockPanel>
[...]

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

You need something like this :

UPDATE P
SET ExtrasPrice = E.TotalPrice
FROM dbo.BookingPitches AS P
INNER JOIN (SELECT BPE.PitchID, Sum(BPE.Price) AS TotalPrice
    FROM BookingPitchExtras AS BPE
    WHERE BPE.[Required] = 1
    GROUP BY BPE.PitchID) AS E ON P.ID = E.PitchID
WHERE P.BookingID = 1

There is a way to do this using the system property "user.dir". The key part to understand is that getAbsoluteFile() must be called (as shown below) or else relative paths will be resolved against the default "user.dir" value.

import java.io.*;

public class FileUtils
{
    public static boolean setCurrentDirectory(String directory_name)
    {
        boolean result = false;  // Boolean indicating whether directory was set
        File    directory;       // Desired current working directory

        directory = new File(directory_name).getAbsoluteFile();
        if (directory.exists() || directory.mkdirs())
        {
            result = (System.setProperty("user.dir", directory.getAbsolutePath()) != null);
        }

        return result;
    }

    public static PrintWriter openOutputFile(String file_name)
    {
        PrintWriter output = null;  // File to open for writing

        try
        {
            output = new PrintWriter(new File(file_name).getAbsoluteFile());
        }
        catch (Exception exception) {}

        return output;
    }

    public static void main(String[] args) throws Exception
    {
        FileUtils.openOutputFile("DefaultDirectoryFile.txt");
        FileUtils.setCurrentDirectory("NewCurrentDirectory");
        FileUtils.openOutputFile("CurrentDirectoryFile.txt");
    }
}

It should be quite simple if you are using LogBack or SLF4J. I do it as below

//imports
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

//Initialize logger
Logger logger = LoggerFactory.getLogger(<classname>.class);
try {
   //try something
} catch(Exception e){
   //Actual logging of error
   logger.error("some message", e);
}

The For-each loop, as it is called, is a type of for loop that is used with collections to guarantee that all items in a collection are iterated over. For example

for ( Object o : objects ) {
    System.out.println(o.toString());
}

Will call the toString() method on each object in the collection "objects". One nice thing about this is that you cannot get an out of bounds exception.

Try following code:

File file = new File("infilename");

// Get the number of bytes in the file
long sizeInBytes = file.length();
//transform in MB
long sizeInMb = sizeInBytes / (1024 * 1024);

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

You can try using the standard W3C way:

.transition { transition: all 0.2s, top 0s, left 0s, width 0s, height 0s; }

Abstract:

The reason why you are getting this error message is because you are trying to call a method on an int type of a variable. This would work if would have called len() function on a list type of a variable. Let's examin the two cases:

Fail:

num = 10

print(len(num))

The above will produce an error similar to yours due to calling len() function on an int type of a variable;

Success:

data = [0, 4, 8, 9, 12]

print(len(data))

The above will work since you are calling a function on a list type of a variable;

?php

/* Database config */

$db_host        = 'localhost';
$db_user        = '~';
$db_pass        = '~';
$db_database    = 'banners'; 

/* End config */


$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_database);
/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

?>

Add this extension somewhere:

extension String {
    mutating func addString(str: String) {
        self = self + str
    }
}

Then you can call it like:

var str1 = "hi"
var str2 = " my name is"
str1.addString(str2)
println(str1) //hi my name is

A lot of good Swift extensions like this are in my repo here, check them out: https://github.com/goktugyil/EZSwiftExtensions

No one has mentioned it, but JavaFX does not compile or run on certain architectures deemed "servers" by Oracle (e.g. Solaris), because of the missing "jfxrt.jar" support. Stick with SWT, until further notice.

If you are a Xamarin user, this is the solution:

   protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle); //always call superclass first

        this.Window.AddFlags(WindowManagerFlags.KeepScreenOn);

        LoadApplication(new App());
    }

I had the same problems. I solved it: I went to https://www.google.com/recaptcha/admin, clicked on the domain and then went to key settings at the bottom.

There I disabled the option below Domain Name Validation Verify the origin of reCAPTCHA solution.

Clicked on save and captcha started working.

Use $http_MY_CUSTOM_HEADER

You can write some-thing like

set my_header $http_MY_CUSTOM_HEADER;
if($my_header != 'some-value') {
#do some thing;
}

Why do people always use jQuery when it isn't necessary?
Why can't people just use simple JavaScript?

var ele = /*Your Form Element*/;
if(ele.addEventListener){
    ele.addEventListener("submit", callback, false);  //Modern browsers
}else if(ele.attachEvent){
    ele.attachEvent('onsubmit', callback);            //Old IE
}

callback is a function that you want to call when the form is being submitted.

About EventTarget.addEventListener, check out this documentation on MDN.

To cancel the native submit event (prevent the form from being submitted), use .preventDefault() in your callback function,

document.querySelector("#myForm").addEventListener("submit", function(e){
    if(!isValid){
        e.preventDefault();    //stop form from submitting
    }
});

Listening to the submit event with libraries

If for some reason that you've decided a library is necessary (you're already using one or you don't want to deal with cross-browser issues), here's a list of ways to listen to the submit event in common libraries:

1. jQuery

   $(ele).submit(callback);
   

   Where ele is the form element reference, and callback being the callback function reference. Reference

    <iframe width="100%" height="100%" src="http://jsfiddle.net/DerekL/wnbo1hq0/show" frameborder="0"></iframe>

2. AngularJS (1.x)

   <form ng-submit="callback()">
   
   $scope.callback = function(){ /*...*/ };
   

   Very straightforward, where $scope is the scope provided by the framework inside your controller. Reference

3. React

   <form onSubmit={this.handleSubmit}>
   
   class YourComponent extends Component {
       // stuff
   
       handleSubmit(event) {
           // do whatever you need here
   
           // if you need to stop the submit event and 
           // perform/dispatch your own actions
           event.preventDefault();
       }
   
       // more stuff
   }
   

   Simply pass in a handler to the onSubmit prop. Reference

4. Other frameworks/libraries

   Refer to the documentation of your framework.

Validation

You can always do your validation in JavaScript, but with HTML5 we also have native validation.

<!-- Must be a 5 digit number -->
<input type="number" required pattern="\d{5}">

You don't even need any JavaScript! Whenever native validation is not supported, you can fallback to a JavaScript validator.

Demo: http://jsfiddle.net/DerekL/L23wmo1L/

At a minimum, change this:

function BlockID() {
    var IDs = new Array();
        images['s'] = "Images/Block_01.png";
        images['g'] = "Images/Block_02.png";
        images['C'] = "Images/Block_03.png";
        images['d'] = "Images/Block_04.png";
    return IDs;
}

To this:

function BlockID() {
    var IDs = new Object();
        IDs['s'] = "Images/Block_01.png";
        IDs['g'] = "Images/Block_02.png";
        IDs['C'] = "Images/Block_03.png";
        IDs['d'] = "Images/Block_04.png";
    return IDs;
}

There are a couple fixes to point out. First, images is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images to IDs. Second, you want to return an Object, not an Array. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array(); to var IDs = new Object();.

After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:

function BlockID() {
    return {
            "s":"Images/Block_01.png"
            ,"g":"Images/Block_02.png"
            ,"C":"Images/Block_03.png"
            ,"d":"Images/Block_04.png"
    };
}

This is, in effect, a way to check whether the expression e can be evaluated to be 0, and if not, to fail the build.

The macro is somewhat misnamed; it should be something more like BUILD_BUG_OR_ZERO, rather than ...ON_ZERO. (There have been occasional discussions about whether this is a confusing name.)

You should read the expression like this:

sizeof(struct { int: -!!(e); }))

1. (e): Compute expression e.

2. !!(e): Logically negate twice: 0 if e == 0; otherwise 1.

3. -!!(e): Numerically negate the expression from step 2: 0 if it was 0; otherwise -1.

4. struct{int: -!!(0);} --> struct{int: 0;}: If it was zero, then we declare a struct with an anonymous integer bitfield that has width zero. Everything is fine and we proceed as normal.

5. struct{int: -!!(1);} --> struct{int: -1;}: On the other hand, if it isn't zero, then it will be some negative number. Declaring any bitfield with negative width is a compilation error.

So we'll either wind up with a bitfield that has width 0 in a struct, which is fine, or a bitfield with negative width, which is a compilation error. Then we take sizeof that field, so we get a size_t with the appropriate width (which will be zero in the case where e is zero).

Some people have asked: Why not just use an assert?

keithmo's answer here has a good response:

These macros implement a compile-time test, while assert() is a run-time test.

Exactly right. You don't want to detect problems in your kernel at runtime that could have been caught earlier! It's a critical piece of the operating system. To whatever extent problems can be detected at compile time, so much the better.

I applied CSS styling to an anchored HREF attribute fully emulating the push button behaviors I needed (hover, active, background-color, etc., etc.). HTML markup is much simpler a-n-d eliminates the get/post complexity associated with using a form-based approach.

Main advantage of MVC architecture is differentiating the layers of a project in Model,View and Controller for the Re-usability of code, easy to maintain code and maintenance. The best thing is the developer feels good to add some code in between the project maintenance.

It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

I found the best anwser, it work for me. Clear the value of bootstrap-datepicker:

$('#datepicker').datepicker('setDate', null);

Add value for boostrap-datepicker:

$('#datepicker').datepicker('setDate', datePicker);

"Valid Signing identity not found" This is because you don't have the private key for distribution certificate.

If the distribution certificate was created originally on a different Mac you may need to import this private key from that Mac. This private key is not available to download from your provisioning portal.

When you import the correct private key to your mac , XCode's organizer will recognize your already downloaded distribution profile as a "Valid profile"

However if you do not have access to the original Mac which created those profiles, the only option you have is revoking profiles.

I needed to just download a file onClick but I needed to run some logic to either fetch or compute the actual url where the file existed. I also did not want to use any anti-react imperative patterns like setting a ref and manually clicking it when I had the resource url. The declarative pattern I used was

onClick = () => {
  // do something to compute or go fetch
  // the url we need from the server
  const url = goComputeOrFetchURL();

  // window.location forces the browser to prompt the user if they want to download it
  window.location = url
}

render() {
  return (
    <Button onClick={ this.onClick } />
  );
}

If adding your routes inside the web middleware doesn't work for any reason then try adding this to $middleware into Kernel.php

        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];

I hope it helps you or anyone with the same problem!

Here is a SUMMARY of all the major answers above (or maybe below later :)

For modern browsers, put css wherever you like it. They would analyze your html file (which they call speculative parsing) and start downloading css in parallel with html parsing.

For old browsers keep putting css on top (if you don't want to show a naked but interactive page first).

For all browsers, put javascript as farther down on the page as possible, since it will halt parsing of your html. Preferably, download it asynchronously (i.e., ajax call)

There are also, some experimental results for a particular case which claims putting javascript first (as opposed to traditional wisdom of putting CSS first) gives better performance but there is no logical reasoning given for it, and lacks validation regarding widespread applicability, so you can ignore it for now.

So, to answer the question: Yes. The recommendation to include the CSS before JS is invalid for the modern browsers. Put CSS wherever you like, and put JS towards the end, as possible.

An alternative to cat() is writeLines():

> writeLines("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename
>

An advantage is that you don't have to remember to append a "\n" to the string passed to cat() to get a newline after your message. E.g. compare the above to the same cat() output:

> cat("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename>

and

> cat("File not supplied.\nUsage: ./program F=filename","\n")
File not supplied.
Usage: ./program F=filename
>

The reason print() doesn't do what you want is that print() shows you a version of the object from the R level - in this case it is a character string. You need to use other functions like cat() and writeLines() to display the string. I say "a version" because precision may be reduced in printed numerics, and the printed object may be augmented with extra information, for example.

If you wish the delete to be automatic, you need to change your schema so that the foreign key constraint is ON DELETE CASCADE.

For more information, see the MSDN page on Cascading Referential Integrity Constraints.

ETA (after clarification from the poster): If you can't update the schema, you have to manually DELETE the affected child records first.

From your local machine:

rsync -chavzP --stats [email protected]:/path/to/copy /path/to/local/storage

From your local machine with a non standard ssh port:

rsync -chavzP -e "ssh -p $portNumber" [email protected]:/path/to/copy /local/path

Or from the remote host, assuming you really want to work this way and your local machine is listening on SSH:

rsync -chavzP --stats /path/to/copy [email protected]:/path/to/local/storage

See man rsync for an explanation of my usual switches.

In Spring MVC, all incoming requests go through a single servlet. This servlet - DispatcherServlet - is the front controller. Front controller is a typical design pattern in the web applications development. In this case, a single servlet receives all requests and transfers them to all other components of the application.

The task of the DispatcherServlet is to send request to the specific Spring MVC controller.

Usually we have a lot of controllers and DispatcherServlet refers to one of the following mappers in order to determine the target controller:

• BeanNameUrlHandlerMapping;
• ControllerBeanNameHandlerMapping;
• ControllerClassNameHandlerMapping;
• DefaultAnnotationHandlerMapping;
• SimpleUrlHandlerMapping.

If no configuration is performed, the DispatcherServlet uses BeanNameUrlHandlerMapping and DefaultAnnotationHandlerMapping by default.

When the target controller is identified, the DispatcherServlet sends request to it. The controller performs some work according to the request (or delegate it to the other objects), and returns back to the DispatcherServlet with the Model and the name of the View.

The name of the View is only a logical name. This logical name is then used to search for the actual View (to avoid coupling with the controller and specific View). Then DispatcherServlet refers to the ViewResolver and maps the logical name of the View to the specific implementation of the View.

Some possible Implementations of the ViewResolver are:

• BeanNameViewResolver;
• ContentNegotiatingViewResolver;
• FreeMarkerViewResolver;
• InternalResourceViewResolver;
• JasperReportsViewResolver;
• ResourceBundleViewResolver;
• TilesViewResolver;
• UrlBasedViewResolver;
• VelocityLayoutViewResolver;
• VelocityViewResolver;
• XmlViewResolver;
• XsltViewResolver.

When the DispatcherServlet determines the view that will display the results it will be rendered as the response.

Finally, the DispatcherServlet returns the Response object back to the client.

My answer here might solve your problem as well:

https://stackoverflow.com/a/27967674/543814

• Instead of Replace, you would use Match.
• Instead of group $1, you would read group $2.
• Group $2 was made non-capturing there, which you would avoid.

Example:

Regex.Match("50% of 50% is 25%", "(\d+\%)|(.+?)");

The first capturing group specifies the pattern that you wish to avoid. The last capturing group captures everything else. Simply read out that group, $2.

This should help to get distinct values of a column:

df.select('column1').distinct().collect()

Note that .collect() doesn't have any built-in limit on how many values can return so this might be slow -- use .show() instead or add .limit(20) before .collect() to manage this.

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

Updated Answer

jQuery changed the location of where events are stored in 1.8. Now you know why it is such a bad idea to mess around with internal APIs :)

The new internal API to access to events for a DOM object is available through the global jQuery object, and not tied to each instance, and it takes a DOM element as the first parameter, and a key ("events" for us) as the second parameter.

jQuery._data(<DOM element>, "events");

So here's the modified code for jQuery 1.8.

// [name] is the name of the event "click", "mouseover", .. 
// same as you'd pass it to bind()
// [fn] is the handler function
$.fn.bindFirst = function(name, fn) {
    // bind as you normally would
    // don't want to miss out on any jQuery magic
    this.on(name, fn);

    // Thanks to a comment by @Martin, adding support for
    // namespaced events too.
    this.each(function() {
        var handlers = $._data(this, 'events')[name.split('.')[0]];
        // take out the handler we just inserted from the end
        var handler = handlers.pop();
        // move it at the beginning
        handlers.splice(0, 0, handler);
    });
};

And here's a playground.

Original Answer

As @Sean has discovered, jQuery exposes all event handlers through an element's data interface. Specifically element.data('events'). Using this you could always write a simple plugin whereby you could insert any event handler at a specific position.

Here's a simple plugin that does just that to insert a handler at the beginning of the list. You can easily extend this to insert an item at any given position. It's just array manipulation. But since I haven't seen jQuery's source and don't want to miss out on any jQuery magic from happening, I normally add the handler using bind first, and then reshuffle the array.

// [name] is the name of the event "click", "mouseover", .. 
// same as you'd pass it to bind()
// [fn] is the handler function
$.fn.bindFirst = function(name, fn) {
    // bind as you normally would
    // don't want to miss out on any jQuery magic
    this.bind(name, fn);

    // Thanks to a comment by @Martin, adding support for
    // namespaced events too.
    var handlers = this.data('events')[name.split('.')[0]];
    // take out the handler we just inserted from the end
    var handler = handlers.pop();
    // move it at the beginning
    handlers.splice(0, 0, handler);
};

So for example, for this markup it would work as (example here):

<div id="me">..</div>

$("#me").click(function() { alert("1"); });
$("#me").click(function() { alert("2"); });    
$("#me").bindFirst('click', function() { alert("3"); });

$("#me").click(); // alerts - 3, then 1, then 2

However, since .data('events') is not part of their public API as far as I know, an update to jQuery could break your code if the underlying representation of attached events changes from an array to something else, for example.

Disclaimer: Since anything is possible :), here's your solution, but I would still err on the side of refactoring your existing code, as just trying to remember the order in which these items were attached can soon get out of hand as you keep adding more and more of these ordered events.

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

We can get official code From the internet! Refer this:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trim

Running the following code before any other code will create trim() if it's not natively available.

if (!String.prototype.trim) {
  (function() {
    // Make sure we trim BOM and NBSP
    var rtrim = /^[\s\uFEFF\xA0]+|[\s\uFEFF\xA0]+$/g;
    String.prototype.trim = function() {
      return this.replace(rtrim, '');
    };
  })();
}

for more: I just found there is js project for supporting EcmaScript 5: https://github.com/es-shims/es5-shim by reading the source code, we can get more knowledge about trim.

defineProperties(StringPrototype, {
 // http://blog.stevenlevithan.com/archives/faster-trim-javascript
 // http://perfectionkills.com/whitespace-deviations/
  trim: function trim() {
    if (typeof this === 'undefined' || this === null) {
      throw new TypeError("can't convert " + this + ' to object');
    }
    return String(this).replace(trimBeginRegexp, '').replace(trimEndRegexp, '');
  }
}, hasTrimWhitespaceBug);

I've also experienced such issues as R.java being missing, and also eclipse complaining there are errors in my code (displaying red X icon against class files) when there were no errors.

The only method I've found for solving this is to clean the project by selecting Project > Clean

This seems to solve the issue for myself, running Eclipse 3.5.2

App Uses Non-Exempt Encryption

For an extensive coverage review the contents of RFC2965. Of course that doesn't necessarily mean that all browsers behave exactly the same way.

However in general the rule for default Path if none specified in the cookie is the path in the URL from which the Set-Cookie header arrived. Similarly the default for the Domain is the full host name in the URL from which the Set-Cookie arrived.

Matching rules for the domain require the cookie Domain to match the host to which the request is being made. The cookie can specify a wider domain match by include *. in the domain attribute of Set-Cookie (this one area that browsers may vary). Matching the path (assuming the domain matches) is a simple matter that the requested path must be inside the path specified on the cookie. Typically session cookies are set with path=/ or path=/applicationName/ so the cookie is available to all requests into the application.

• Will a cookie for .example.com be available for www.example.com? Yes
• Will a cookie for .example.com be available for example.com? Don't Know
• Will a cookie for example.com be available for www.example.com? Shouldn't but... *
• Will a cookie for example.com be available for anotherexample.com? No
• Will www.example.com be able to set cookie for example.com? Yes
• Will www.example.com be able to set cookie for www2.example.com? No (Except via .example.com)
• Will www.example.com be able to set cookie for .com? No (Can't set a cookie this high up the namespace nor can you set one for something like .co.uk).

* I'm unable to test this right now but I have an inkling that at least IE7/6 would treat the path example.com as if it were .example.com.

Try this:

<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
        $data = array_map("utf8_encode", $data); //added
        $num = count ($data);
        for ($c=0; $c < $num; $c++) {
            // output data
            echo "<td>$data[$c]</td>";
        }
        echo "</tr><tr>";
}
?>

You have to workaround this via static application context accessor approach:

@Component
public class StaticContextAccessor {

    private static StaticContextAccessor instance;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void registerInstance() {
        instance = this;
    }

    public static <T> T getBean(Class<T> clazz) {
        return instance.applicationContext.getBean(clazz);
    }

}

Then you can access bean instances in a static manner.

public class Boo {

    public static void randomMethod() {
         StaticContextAccessor.getBean(Foo.class).doStuff();
    }

}

You could add a method to String to make it more semantic:

String.metaClass.getNotBlank = { !delegate.allWhitespace }

which let's you do:

groovy:000> foo = ''
===> 
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true

from the command line (cmd.exe, not from within mysql shell) try something like:

type c:/nite.sql | mysql -uuser -ppassword dbname

In my case, I was missing something really trivial.

<input value={state.myObject.inputValue} />

My state was the following when I was getting the warning:

state = {
   myObject: undefined
}

By alternating my state to reference the input of my value, my issue was solved:

state = {
   myObject: {
      inputValue: ''
   }
}

I use this with good results:

border-style:hidden;

It also works for:

border-right-style:hidden; /*if you want to hide just a border on a cell*/

Example:

<style type="text/css">_x000D_
      table, th, td {_x000D_
       border: 2px solid green;_x000D_
      }_x000D_
      tr.hide_right > td, td.hide_right{_x000D_
        border-right-style:hidden;_x000D_
      }_x000D_
      tr.hide_all > td, td.hide_all{_x000D_
        border-style:hidden;_x000D_
      }_x000D_
  }_x000D_
</style>_x000D_
<table>_x000D_
  <tr>_x000D_
    <td class="hide_right">11</td>_x000D_
    <td>12</td>_x000D_
    <td class="hide_all">13</td>_x000D_
  </tr>_x000D_
  <tr class="hide_right">_x000D_
    <td>21</td>_x000D_
    <td>22</td>_x000D_
    <td>23</td>_x000D_
  </tr>_x000D_
  <tr class="hide_all">_x000D_
    <td>31</td>_x000D_
    <td>32</td>_x000D_
    <td>33</td>_x000D_
  </tr>_x000D_
</table>

Here is the result:

Try this...

//global declaration
private TextView timeUpdate;
Calendar calendar;

.......

timeUpdate = (TextView) findViewById(R.id.timeUpdate); //initialize in onCreate()

.......

//in onStart()
calendar = Calendar.getInstance();
//date format is:  "Date-Month-Year Hour:Minutes am/pm"
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy HH:mm a"); //Date and time
String currentDate = sdf.format(calendar.getTime());

//Day of Name in full form like,"Saturday", or if you need the first three characters you have to put "EEE" in the date format and your result will be "Sat".
SimpleDateFormat sdf_ = new SimpleDateFormat("EEEE"); 
Date date = new Date();
String dayName = sdf_.format(date);
timeUpdate.setText("" + dayName + " " + currentDate + "");

The result is...

happy coding.....

This is the great description and step-by-step instruction how to create and manage master and slave (gcc and g++) alternatives.

Shortly it's:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.7 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.7
sudo update-alternatives --config gcc

try these line of codes working in my case:

IEnumerable<string> values = new List<string>();
this.Request.Headers.TryGetValues("Authorization", out values);

As we were already using jQuery for a graphical eye-candy feature we ended up using this. A code like

$(document).ready(function() {
    // any code goes here
    init();
});

did everything we wanted and cares about browser incompatibilities at its own.

WOW... In appreciation, I add a bit of code that I use to find the path to ADOBE

Private Declare Function FindExecutable Lib "shell32.dll" Alias "FindExecutableA" _
    (ByVal lpFile As String, _
     ByVal lpDirectory As String, _
     ByVal lpResult As String) As Long

and call this to find the applicable program name

Public Function GetFileAssociation(ByVal sFilepath As String) As String
Dim i               As Long
Dim E               As String
    GetFileAssociation = "File not found!"
    If Dir(sFilepath) = vbNullString Or sFilepath = vbNullString Then Exit Function
    GetFileAssociation = "No association found!"
    E = String(260, Chr(0))
    i = FindExecutable(sFilepath, vbNullString, E)
    If i > 32 Then GetFileAssociation = Left(E, InStr(E, Chr(0)) - 1)
End Function

Thank you for your code, which isn't EXACTLY what I wanted, but can be adapted for me.

you can use this function . Its taken from https://convertintowordpress.com/simple-jquery-table-pagination-code/

function pagination(){
    var req_num_row=10;
    var $tr=jQuery('tbody tr');
    var total_num_row=$tr.length;
    var num_pages=0;
    if(total_num_row % req_num_row ==0){
        num_pages=total_num_row / req_num_row;
    }
    if(total_num_row % req_num_row >=1){
        num_pages=total_num_row / req_num_row;
        num_pages++;
        num_pages=Math.floor(num_pages++);
    }
    for(var i=1; i<=num_pages; i++){
        jQuery('#pagination').append("<a href='#' class='btn'>"+i+"</a>");
    }
    $tr.each(function(i){
        jQuery(this).hide();
        if(i+1 <= req_num_row){
            $tr.eq(i).show();
        }

    });
    jQuery('#pagination a').click(function(e){
        e.preventDefault();
        $tr.hide();
        var page=jQuery(this).text();
        var temp=page-1;
        var start=temp*req_num_row;
        //alert(start);

        for(var i=0; i< req_num_row; i++){

            $tr.eq(start+i).show();

        }
    });
}

For yet another concrete use case, use double brackets when you want to select a data frame created by the split() function. If you don't know, split() groups a list/data frame into subsets based on a key field. It's useful if when you want to operate on multiple groups, plot them, etc.

> class(data)
[1] "data.frame"

> dsplit<-split(data, data$id)
> class(dsplit)
[1] "list"

> class(dsplit['ID-1'])
[1] "list"

> class(dsplit[['ID-1']])
[1] "data.frame"

try this;

select gid
from `gd`
group by gid 
having count(*) > 10
order by lastupdated desc

I have a workaround that works woo and it pretty simple... although performance is prob not the pest... but it works and works well.

The trick is that until private properties and functions are established and standardized/adopted work arounds are required and this is another workaround...

class ClassPrivateProperties {
    constructor(instance) {
        const $this = instance;
        let properties = {};
        this.prop = (key, value = undefined) => {
            if (!value) {
                return properties[key];
            } else {
                properties[key] = value;
            }
        };
        this.clear = instance => {
            if ($this === instance) {
                properties = {};
                return true;
            } else {
                return false;
            }
        }
    }
}

This is a sample usage that can be what ever (also if you use the above feel free to make it better)

class Test {
    constructor() {
        this._privateProps = new ClassPrivateProperties(this);
    }
    property(key, value = undefined) {
        if (!value) {
            return this._privateProps.prop(key);
        } else {
            this._privateProps.prop(key, value);
        }
    }
    clear() { return this._privateProps.clear(this); }
}
const test = new test;
test.property('myKey','some value here');
console.log(test.property('myKey'));

Like I mentioned that this prob not the best of the best but it works and makes properties truly private.

select round(rand(checksum(newid()))*(10)+20,2)

Here the random number will come in between 20 and 30. round will give two decimal place maximum.

If you want negative numbers you can do it with

select round(rand(checksum(newid()))*(10)-60,2)

Then the min value will be -60 and max will be -50.

XmlDocument is great for developers who are familiar with the XML DOM object model. It's been around for a while, and more or less corresponds to a W3C standard. It supports manual navigation as well as XPath node selection.

XDocument powers the LINQ to XML feature in .NET 3.5. It makes heavy use of IEnumerable<> and can be easier to work with in straight C#.

Both document models require you to load the entire document into memory (unlike XmlReader for example).

There are a few. I was looking into MBTrading for a friend. I didn't get too far, as my friend lost interest. Seemed relatively straigt forward with a C# and VB.Net SDK. They had some docs and everything. This was ~6 months ago, so it may be better (or worse) by now.

IIRC, you can create a demo account for free. I don't remember all the details, but it let you connect to their test server and pull quotes and make fake trades and such to get your software fine tuned.

Don't know much about cost for an actual account or anything.

If you use Spring you can:

1) create a log4j configuration file, e.g. "/WEB-INF/classes/log4j-myapp.properties" DO NOT name it "log4j.properties"

Example:

log4j.rootLogger=ERROR, stdout, rollingFile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=${myWebapp-instance-root}/WEB-INF/logs/application.log
log4j.appender.rollingFile.MaxFileSize=512KB
log4j.appender.rollingFile.MaxBackupIndex=10
log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.rollingFile.Encoding=UTF-8

We'll define "myWebapp-instance-root" later on point (3)

2) Specify config location in web.xml:

<context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>/WEB-INF/classes/log4j-myapp.properties</param-value>
</context-param>

3) Specify a unique variable name for your webapp's root, e.g. "myWebapp-instance-root"

<context-param>
  <param-name>webAppRootKey</param-name>
  <param-value>myWebapp-instance-root</param-value>
</context-param>

4) Add a Log4jConfigListener:

<listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

If you choose a different name, remember to change it in log4j-myapp.properties, too.

See my article (Italian only... but it should be understandable): http://www.megadix.it/content/configurare-path-relativi-log4j-utilizzando-spring

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

You can query results for a particular hashtag (snowy in this case) using the following url

It is rate limited to 5000 (X-Ratelimit-Limit:5000) per hour

You can play around here :

https://apigee.com/console/instagram?req=%7B%22resource%22%3A%22get_tags_media_recent%22%2C%22params%22%3A%7B%22query%22%3A%7B%7D%2C%22template%22%3A%7B%22tag-name%22%3A%22snowy%22%7D%2C%22headers%22%3A%7B%7D%2C%22body%22%3A%7B%22attachmentFormat%22%3A%22mime%22%2C%22attachmentContentDisposition%22%3A%22form-data%22%7D%7D%2C%22verb%22%3A%22get%22%7D

You need to use "Authentication" as OAuth 2 and will be prompted to signin via Instagram. Post that you might have to reneter the "tag-name" in "Template" section.

All the pagination related data is available in the "pagination" parameter in the response and use it's "next_url" to query for the next set of result.

I use this code for cross domain ajax call, I hope it will help more than one here. I'm using Prototype library and you can do the same with JQuery or Dojo or anything else:

Step 1: create a new js file and put this class inside, I called it xss_ajax.js

var WSAjax = Class.create ({
    initialize: function (_url, _callback){
        this.url = _url ;
        this.callback = _callback ;
        this.connect () ;
    },
    connect: function (){
        var script_id = null;
        var script = document.createElement('script');
        script.setAttribute('type', 'text/javascript');
        script.setAttribute('src', this.url);
        script.setAttribute('id', 'xss_ajax_script');

        script_id = document.getElementById('xss_ajax_script');
        if(script_id){
            document.getElementsByTagName('head')[0].removeChild(script_id);
        }

        // Insert <script> into DOM
        document.getElementsByTagName('head')[0].appendChild(script);
    },
    process: function (data){
        this.callback(data) ;
    }

This class creates a dynamic script element which src attributes targets your JSON data provider (JSON-P in fact as your distant server must provide the data in this format :: call_back_function(//json_data_here) :: so when the script tag is created your JSON will be directly evaled as a function (we'll talk about passing the callback method name to server on step 2), the main concept behind this is that script like img elements are not concerned by the SOP constraints.

Step2: in any html page where you wanna pull the JSON asynchronously (we call this AJAJ ~ Asynchronous JAvascript + JSON :-) instead of AJAX which use the XHTTPRequest object) do like below

//load Prototype first
//load the file you've created in step1


var xss_crawler = new WSAjax (
     "http://your_json_data_provider_url?callback=xss_crawler.process"
 ,   function (_data){
            // your json data is _data and do whatever you like with it 
        }) ;

D'you remenber the callback on step 1? so we pass it to the server and it will returns the JSON embeded in that method so in our case the server will return an evalable javascript code xss_crawler.process(//the_json_data), remember that xss_crawler is an instance of WSAjax class. The server code depends on you (if it's yours), but most of Ajax data providers let you specify the callback method in parameters like we did. In Ruby on rails I just did

render :json=>MyModel.all(:limit=>10), :callback => params[:callback],:content_type => "application/json"

and that's all, you can now pull data from another domain from your apps (widgets, maps etc), in JSON format only, don't forget.

I hope it was helpfull, thanks for your patience :-), peace and sorry for code formatting, it doesn't work well

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

Would like to outline a brief semantic parallel to an already correct answer.

In 'simple' terms, a recursive CTE can be semantically defined as the following parts:

1: The CTE query. Also known as ANCHOR.

2: The recursive CTE query on the CTE in (1) with UNION ALL (or UNION or EXCEPT or INTERSECT) so the ultimate result is accordingly returned.

3: The corner/termination condition. Which is by default when there are no more rows/tuples returned by the recursive query.

A short example that will make the picture clear:

;WITH SupplierChain_CTE(supplier_id, supplier_name, supplies_to, level)
AS
(
SELECT S.supplier_id, S.supplier_name, S.supplies_to, 0 as level
FROM Supplier S
WHERE supplies_to = -1    -- Return the roots where a supplier supplies to no other supplier directly

UNION ALL

-- The recursive CTE query on the SupplierChain_CTE
SELECT S.supplier_id, S.supplier_name, S.supplies_to, level + 1
FROM Supplier S
INNER JOIN SupplierChain_CTE SC
ON S.supplies_to = SC.supplier_id
)
-- Use the CTE to get all suppliers in a supply chain with levels
SELECT * FROM SupplierChain_CTE

Explanation: The first CTE query returns the base suppliers (like leaves) who do not supply to any other supplier directly (-1)

The recursive query in the first iteration gets all the suppliers who supply to the suppliers returned by the ANCHOR. This process continues till the condition returns tuples.

UNION ALL returns all the tuples over the total recursive calls.

Another good example can be found here.

PS: For a recursive CTE to work, the relations must have a hierarchical (recursive) condition to work on. Ex: elementId = elementParentId.. you get the point.

You need to modify 3 things in order to make Google USB driver work for any android phone on any Windows:

1. Add your device's ID to android_winusb.inf file
2. Digitally sign the modified driver
3. Add your device's vendor ID to adb_usb.ini whitelist (no longer required)

and here are the details:

1. Add your device's ID to android_winusb.inf file

the format to add is:

;Comment usually the device name
%SingleAdbInterface% = USB_Install, USB\; here you put VID and PID
%CompositeAdbInterface% = USB_Install, USB\; same as above but add the MI

before I go on, VID is the USB Vendor ID.

How to get the vid and pid : they are in drivers you are merging; but if you don’t have a driver for the device you can get it by opening device manager; then right-click the device – select properties-in new dialog go to Details tab >in property drop menu select hardware ids. for example you see something like:

USB\VID_2207&PID_0000&REV_0222&MI_01
USB\VID_2207&PID_0000&MI_01

take this value for composite adb device and remove MI for single adb device, you get

;MSI WindPad Enjoy 7 plus
%SingleAdbInterface%        = USB_Install, USB\VID_2207&PID_0000
%CompositeAdbInterface%     = USB_Install, USB\VID_2207&PID_0000&REV_0222&MI_01
;

copy this 2 line TWICE , once to [Google.NTx86] section and another to [Google.NTamd64] section

REPEAT for every device you want to support

Now an optional edit for [Strings] Section: edit

[Strings]
ProviderName                = “Google, Inc.”
SingleAdbInterface          = “Android ADB Interface”
CompositeAdbInterface       = “Android Composite ADB Interface”
SingleBootLoaderInterface   = “Android Bootloader Interface”
WinUSB_SvcDesc              = “Android USB Driver”
DISK_NAME                   = “Android WinUsb installation disk”
ClassName                   = “Android Device”

To:

[Strings]
ProviderName                = “Google, Inc.”
SingleAdbInterface          = “MSI ADB Interface”
CompositeAdbInterface       = “MSI Composite ADB Interface”
SingleBootLoaderInterface   = “MSI Bootloader Interface”
WinUSB_SvcDesc              = “MSI USB Driver”
DISK_NAME                   = “MSI WinUsb installation disk”
ClassName                   = “MSI Tablet”

2. Digitally sign the modified driver:

Although the original google usb driver was signed by google , modifying android_winusb.inf will prevent installing it on windows 8 showning an error message

The hash file is not present in the specified catalog file. The file is likely
corrupt    or the    victim of tampering.

This is only in Windows 8. Windows 7 or earlier do not show this error message. You have to regenerate catalog file (probably with Windows SDK) and sign

Workaround: A workaround for internal tesing is to diable windows signature verification : either temporarily or permanently:

temporarily:

Go to left upper or lower corner of screen to open charms bar and click settings charm.

choose Change PC settings

choose General

Scroll down, and click ‘Restart now’ under ‘Advanced startup’.

Click ‘Troubleshoot’. Click ‘Advanced Options’ Click ‘Windows Startup Settings’ Click Restart.

or

run cmd and type:

shutdown -o -r -t 0

then after restarting choose ‘Disable driver signature enforcement‘ from the list . install your driver before restarting.

Permanently:

press Window+Q

search for cmd

right click cmd

choose run as administrator from action bar

type in cmd:

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

3. Add your device's vendor ID to adb_usb.ini whitelist (no longer required):

adb used to have a hard-coded whitelist of supported Vendor IDs. If your device's vendor was not on the list - the adb was ignoring it completely. To make adb recognize such devices users had to manually add their vendor IDs to %USERPROFILE%\.android\adb_usb.ini - one ID per line.

in the command line:

echo 0x2207 >> "%USERPROFILE%\.android\adb_usb.ini"

Fortunately, Google has removed the VendorID filtering in more recent adb versions. So this step is no longer required.

Finally you can test installation by :

adb kill-server
adb start-server
adb devices

and enabling debugging in developer options on android device

This should restart ADB Server and list devices. If driver is working ok, the device should be listed.

From SQL Server point of view:

Clustering will give you an active - passive configuration. Meaning in a 2 node cluster, one of them will be the active (serving) and the other one will be passive (waiting to take over when the active node fails). It's a high availability from hardware point of view.

You can have an active-active cluster, but it will require multiple instances of SQL Server running on each node. (i.e. Instance 1 on Node A failing over to Instance 2 on Node B, and instance 1 on Node B failing over to instance 2 on Node A).

Load balancing (at least from SQL Server point of view) does not exists (at least in the same sense of web server load balancing). You can't balance load that way. However, you can split your application to run on some database on server 1 and also run on some database on server 2, etc. This is the primary mean of "load balancing" in SQL world.

I don't think you can downcast an object, however there is a simple way to "downcast" the object outside the box. It isn't type safe, but it works. First serialize the object into json, then deserialize it into the child class object. It works the same as if you were passing the object between apis. So, while there are some people who may say "this doesn't work or isn't good", I would argue that it is exactly the way our internet currently works, so... why not use that method? No mapping required as long as parameter names are the same, and they will be if it is a child class. Note: This will likely not copy any private fields; if you have a constructor with parameters, this probably needs to be tested as well to ensure there aren't side effects.

Here's my toolbox:

public static string ConvertToJson<T>(this T obj)
{
    return JsonConvert.SerializeObject(obj);
}
public static T ConvertToObject<T>(this string json)
{
    if (string.IsNullOrEmpty(json))
    {
        return Activator.CreateInstance<T>();
    }
    return JsonConvert.DeserializeObject<T>(json);
}

Here's how to use it:

var sfcl = networkClient.ConvertToJson().ConvertToObject<SkyfilterClient>();

You're very close, the problem is you're comparing a DateTime to a TimeOfDay. What you need to do is add the .TimeOfDay property to the end of your Convert.ToDateTime() functions.

For ASP.NET MVC if you want to make an exception for leaving the page via submitting a particular form:

Set a form id:

@using (Html.BeginForm("Create", "MgtJob", FormMethod.Post, new { id = "createjob" }))
{
  // Your code
}



<script type="text/javascript">

  // Without submit form
   $(window).bind('beforeunload', function () {
        if ($('input').val() !== '') {
            return "It looks like you have input you haven't submitted."
        }
    });

    // this will call before submit; and it will unbind beforeunload
    $(function () {
        $("#createjob").submit(function (event) {
            $(window).unbind("beforeunload");
        });
    });

</script>

1. Normal Class: A Java class

2. Java Beans:

   • All properties private (use getters/setters)
   • A public no-argument constructor
   • Implements Serializable.

3. Pojo: Plain Old Java Object is a Java object not bound by any restriction other than those forced by the Java Language Specification. I.e., a POJO should not have to

   • Extend prespecified classes
   • Implement prespecified interface
   • Contain prespecified annotations

I've had issues with using SELECT last_insert_rowid() in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.

Here's where they state that in the doco:

If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.

That's from sqlite.org doco

This is because, in the constructor, you declared a local variable with the same name as an attribute.

To allocate an integer array which all elements are initialized to zero, write this in the constructor:

data = new int[3];

To allocate an integer array which has other initial values, put this code in the constructor:

int[] temp = {2, 3, 7};
data = temp;

or:

data = new int[] {2, 3, 7};

Using Value2 gives a performance benefit. As per Charles Williams blog

Range.Value2 works the same way as Range.Value, except that it does not check the cell format and convert to Date or Currency. And thats probably why its faster than .Value when retrieving numbers.

So

DirArray = [a1:a5].Value2

Bonus Reading

• Range.Value: Returns or sets a Variant value that represents the value of the specified range.
• Range.Value2: The only difference between this property and the Value property is that the Value2 property doesn't use the Currency and Date data types.

These answers are all outdated for those utilizing the HttpClient rather than Http. I was starting to go crazy thinking, "I have done the import of URLSearchParams but it still doesn't work without .toString() and the explicit header!"

With HttpClient, use HttpParams instead of URLSearchParams and note the body = body.append() syntax to achieve multiple params in the body since we are working with an immutable object:

login(userName: string, password: string): Promise<boolean> {
    if (!userName || !password) {
      return Promise.resolve(false);
    }

    let body: HttpParams = new HttpParams();
    body = body.append('grant_type', 'password');
    body = body.append('username', userName);
    body = body.append('password', password);

    return this.http.post(this.url, body)
      .map(res => {
        if (res) {          
          return true;
        }
        return false;
      })
      .toPromise();
  }

In android studio 2.3.3 (windows) you must go to C:\User\ (Name)\ .AndroidStudio2.3\config\option open recentProjects.xml And change your directory

<option name="lastProjectLocation" value="YOUR DIRECTORY" />

return (new StringBuilder("select id1, " + " id2 " + " from " + " table"))
     .toString();

So as you point out, the example you give is a simplistic but let's analyze it anyway. What happens here is the compiler actually does the + work here because "select id1, " + " id2 " + " from " + " table" are all constants. So this turns into:

return new StringBuilder("select id1,  id2  from  table").toString();

In this case, obviously, there is no point in using StringBuilder. You might as well do:

// the compiler combines these constant strings
return "select id1, " + " id2 " + " from " + " table";

However, even if you were appending any fields or other non-constants then the compiler would use an internal StringBuilder -- there's no need for you to define one:

// an internal StringBuilder is used here
return "select id1, " + fieldName + " from " + tableName;

Under the covers, this turns into code that is approximately equivalent to:

StringBuilder sb = new StringBuilder("select id1, ");
sb.append(fieldName).append(" from ").append(tableName);
return sb.toString();

Really the only time you need to use StringBuilder directly is when you have conditional code. For example, code that looks like the following is desperate for a StringBuilder:

// 1 StringBuilder used in this line
String query = "select id1, " + fieldName + " from " + tableName;
if (where != null) {
   // another StringBuilder used here
   query += ' ' + where;
}

The + in the first line uses one StringBuilder instance. Then the += uses another StringBuilder instance. It is more efficient to do:

// choose a good starting size to lower chances of reallocation
StringBuilder sb = new StringBuilder(64);
sb.append("select id1, ").append(fieldName).append(" from ").append(tableName);
// conditional code
if (where != null) {
   sb.append(' ').append(where);
}
return sb.toString();

Another time that I use a StringBuilder is when I'm building a string from a number of method calls. Then I can create methods that take a StringBuilder argument:

private void addWhere(StringBuilder sb) {
   if (where != null) {
      sb.append(' ').append(where);
   }
}

When you are using a StringBuilder, you should watch for any usage of + at the same time:

sb.append("select " + fieldName);

That + will cause another internal StringBuilder to be created. This should of course be:

sb.append("select ").append(fieldName);

Lastly, as @T.J.rowder points out, you should always make a guess at the size of the StringBuilder. This will save on the number of char[] objects created when growing the size of the internal buffer.

A little modification to typescript:

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

If you want to create and copy the content in a single shot, just use the SELECT:

CREATE TABLE new_tbl SELECT * FROM orig_tbl;

For those using Yarn as their package manager instead of npm:

yarn global add babel-cli

Here's the correct code for your service:

myApp.service('userService', [
  '$http', '$q', '$rootScope', '$location', function($http, $q, $rootScope, $location) {

    var user = {
      access: false
    };

    var me = this;

    this.initialized = false;
    this.isAuthenticated = function() {

      var deferred = $q.defer();
      user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      deferred.resolve(user);
      me.initialized = true;

      return deferred.promise;
    };
  }
]);

Then you controller should align accordingly:

myApp.run([
  '$rootScope', 'userService', function($rootScope, userService) {
    return userService.isAuthenticated().then(function(user) {
      if (user) {
        // You have access to the object you passed in the service, not to the response.
        // You should either put response.data on the user or use a different property.
        return $rootScope.$broadcast('login', user.email);  
      } else {
        return userService.logout();
      }
    });
  }
]);

Few points to note about the service:

• Expose in a service only what needs to be exposed. User should be kept internally and be accessed by getters only.

• When in functions, use 'me' which is the service to avoid edge cases of this with javascript.

• I guessed what initialized was meant to do, feel free to correct me if I guessed wrong.

As a summary

import sys
import re

f = sys.argv[1]
find = sys.argv[2]
replace = sys.argv[3]
with open (f, "r") as myfile:
     s=myfile.read()
ret = re.sub(find,replace, s)   # <<< This is where the magic happens
print ret

The template it is referring to is the Html helper DisplayFor.

DisplayFor expects to be given an expression that conforms to the rules as specified in the error message.

You are trying to pass in a method chain to be executed and it doesn't like it.

This is a perfect example of where the MVVM (Model-View-ViewModel) pattern comes in handy.

You could wrap up your Trainer model class in another class called TrainerViewModel that could work something like this:

class TrainerViewModel
{
    private Trainer _trainer;

    public string ShortDescription
    {
        get
        {
            return _trainer.Description.ToString().Substring(0, 100);
        }
    }

    public TrainerViewModel(Trainer trainer)
    {
        _trainer = trainer;
    }
}

You would modify your view model class to contain all the properties needed to display that data in the view, hence the name ViewModel.

Then you would modify your controller to return a TrainerViewModel object rather than a Trainer object and change your model type declaration in your view file to TrainerViewModel too.

var first_value = '2';
// convert this string value into int
parseInt(first_value);

use .val(), it will return the value of the <input>

$("#spa").val().length > 0

And you had a typo, length not lenght.

Try this. It works for me. The reason is well explained here..

Here is a compilation of verified information from the various answers and cited references in this thread:

1. command.com is the 16-bit command processor introduced in MS-DOS and was also used in the Win9x series of operating systems.
2. cmd.exe is the 32-bit command processor in Windows NT (64-bit Windows OSes also have a 64-bit version). cmd.exe was never part of Windows 9x. It originated in OS/2 version 1.0, and the OS/2 version of cmd began 16-bit (but was nonetheless a fully fledged protected mode program with commands like start). Windows NT inherited cmd from OS/2, but Windows NT's Win32 version started off 32-bit. Although OS/2 went 32-bit in 1992, its cmd remained a 16-bit OS/2 1.x program.
3. The ComSpec env variable defines which program is launched by .bat and .cmd scripts. (Starting with WinNT this defaults to cmd.exe.)
4. cmd.exe is backward compatible with command.com.
5. A script that is designed for cmd.exe can be named .cmd to prevent accidental execution on Windows 9x. This filename extension also dates back to OS/2 version 1.0 and 1987.

Here is a list of cmd.exe features that are not supported by command.com:

• Long filenames (exceeding the 8.3 format)
• Command history
• Tab completion
• Escape character: ^ (Use for: \ & | > < ^)
• Directory stack: PUSHD/POPD
• Integer arithmetic: SET /A i+=1
• Search/Replace/Substring: SET %varname:expression%
• Command substitution: FOR /F (existed before, has been enhanced)
• Functions: CALL :label

Order of Execution:

If both .bat and .cmd versions of a script (test.bat, test.cmd) are in the same folder and you run the script without the extension (test), by default the .bat version of the script will run, even on 64-bit Windows 7. The order of execution is controlled by the PATHEXT environment variable. See Order in which Command Prompt executes files for more details.

Basically, you should add a specific unique field. I usually use xxxUri fields.

class User {

    @Id
    // automatically generated
    private Long id;

    // globally unique id
    @Column(name = "SCN", nullable = false, unique = true)
    private String scn;
}

And you business method will do like this.

public User findUserByScn(@NotNull final String scn) {
    CriteriaBuilder builder = manager.getCriteriaBuilder();
    CriteriaQuery<User> criteria = builder.createQuery(User.class);
    Root<User> from = criteria.from(User.class);
    criteria.select(from);
    criteria.where(builder.equal(from.get(User_.scn), scn));
    TypedQuery<User> typed = manager.createQuery(criteria);
    try {
        return typed.getSingleResult();
    } catch (final NoResultException nre) {
        return null;
    }
}

You need to add your ssh key to your git account,if it throws error then delete previous ssh key and create a new ssh key then add.

GitHub's support determined the root of the issue right away: Two-factor authorization.

To use GitHub over the shell with https, create an OAuth token. As the page notes, I did have to remove my username and password credentials from Keychain but with osx-keychain in place, the token is stored as the password and things work exactly as they would over https without two-factor authorization in place.

You can calculate the cumulative sum list in linear time with a simple for loop:

def csum(lst):
    s = lst.copy()
    for i in range(1, len(s)):
        s[i] += s[i-1]
    return s

time_interval = [4, 6, 12]
print(csum(time_interval))  # [4, 10, 22]

The standard library's itertools.accumulate may be a faster alternative (since it's implemented in C):

from itertools import accumulate
time_interval = [4, 6, 12]
print(list(accumulate(time_interval)))  # [4, 10, 22]

The accepted answer is fine, but I'd like to add something to this as I was using IntelliJ on Mac and couldn't get it to work using the JAVA_HOME path variable.

It turns out Java Home was different when running the application from IntelliJ.

To figure out exactly where it is, you can just do System.getProperty("java.home") as that's where the trusted certificates are read from.

One difference is that in a DTD the content model of an element is completely determined by its name, independently of where it appears in the document:

Assuming you want to have

• a person element
• with a child element called name
• an name itself has child elements first and last.

Like this

   <person>
       <name>
            <first></first>
            <last></last>
       </name>
   </person>

If a city element in the same document also needs to have a child element 'name' the DTD requires that this 'name' element must have child elements first and last as well. Despite the fact that city.name does not require first and last as children.

In contrast, XML Schema allows you to declare child element types locally; you could declare the name child elements for both person and city separately. Thus giving them their proper content models in those contexts.

The other major difference is support for namespaces. Since DTDs are part of the original XML specification (and inherited from SGML), they are not namespace-aware at all because XML namespaces were specified later. You can use DTDs in combination with namespaces, but it requires some contortions, like being forced to define the prefixes in the DTD and using only those prefixes, instead of being able to use arbitrary prefixes.

To me, other differences are mostly superficial. Datatype support could easily be added to DTDs, and syntax is just syntax. (I, for one, find the XML Schema syntax horrible and would never want to hand-maintain an XML Schema, which I wouldn't say about DTDs or RELAX NG schemas; if I need an XML Schema for some reason, I usually write a RELAX NG one and convert it with trang.)

If you are using c# on the desktop, you can use SimpleMapi. That way it will be sent using the default mail client, and the user has the option of reviewing the message before sending, just like mailto:.

To use it you add the Simple-MAPI.NET package (it's 13Kb), and run:

var mapi = new SimpleMapi();
mapi.AddRecipient(null, address, false);
mapi.Attach(path);
//mapi.Logon(ParentForm.Handle);    //not really necessary
mapi.Send(subject, body, true);

What you describe is the correct way to handle this.

You said that you want to stay in the GUI. You can usually set the execute bit through the file properties menu. You could also learn how to create a custom action for the context menu to do this for you if you're so inclined. This depends on your desktop environment of course.

If you use a more advanced editor, you can script the action to happen when the file is saved. For example (I'm only really familiar with vim), you could add this to your .vimrc to make any new file that starts with "#!/*/bin/*" executable.

au BufWritePost * if getline(1) =~ "^#!" | if getline(1) =~ "/bin/" | silent !chmod +x <afile> | endif | endif

If you want to search as string, you can cast to text like this:

SELECT * FROM books WHERE price::TEXT LIKE '123%'

This problem occurs due to missing import of FormsModule,ReactiveFormsModule .I also came with same problem. My case was diff. as i was working with modules.So i missed above imports in my parent modules though i had imported it into child modules,it wasn't working.

Then i imported it into my parent modules as below, and it worked!

import { ReactiveFormsModule,FormsModule  } from '@angular/forms';
import { AlertModule } from 'ngx-bootstrap';

         @NgModule({
          imports: [
            CommonModule,
            FormsModule,
            ReactiveFormsModule,
    ],
      declarations: [MyComponent]
    })

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

I'm assuming you're using express, given the logs you have in your question. The key is to set the timeout property on server (the following sets the timeout to one second, use whatever value you want):

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});
server.timeout = 1000;

If you're not using express and are only working with vanilla node, the principle is the same. The following will not return data:

var http = require('http');
var server = http.createServer(function (req, res) {
  setTimeout(function() {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
  }, 200);
}).listen(1337, '127.0.0.1');

server.timeout = 20;
console.log('Server running at http://127.0.0.1:1337/');

Ruby uses the case for writing switch statements.

As per the case documentation:

Case statements consist of an optional condition, which is in the position of an argument to case, and zero or more when clauses. The first when clause to match the condition (or to evaluate to Boolean truth, if the condition is null) “wins”, and its code stanza is executed. The value of the case statement is the value of the successful when clause, or nil if there is no such clause.

A case statement can end with an else clause. Each when a statement can have multiple candidate values, separated by commas.

Example:

case x
when 1,2,3
  puts "1, 2, or 3"
when 10
  puts "10"
else
  puts "Some other number"
end

Shorter version:

case x
when 1,2,3 then puts "1, 2, or 3"
when 10 then puts "10"
else puts "Some other number"
end

And as "Ruby's case statement - advanced techniques" describes Ruby case;

Can be used with Ranges:

case 5
when (1..10)
  puts "case statements match inclusion in a range"
end

## => "case statements match inclusion in a range"

Can be used with Regex:

case "FOOBAR"
when /BAR$/
  puts "they can match regular expressions!"
end

## => "they can match regular expressions!"

Can be used with Procs and Lambdas:

case 40
when -> (n) { n.to_s == "40" }
  puts "lambdas!"
end

## => "lambdas"

Also, can be used with your own match classes:

class Success
  def self.===(item)
    item.status >= 200 && item.status < 300
  end
end

class Empty
  def self.===(item)
    item.response_size == 0
  end
end

case http_response
when Empty
  puts "response was empty"
when Success
  puts "response was a success"
end

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

In case you're using the option stream=True you can do this:

r = requests.get(
    'http://url_to_large_file',
    timeout=1,  # relevant only for underlying socket
    stream=True)

with open('/tmp/out_file.txt'), 'wb') as f:
    start_time = time.time()
    for chunk in r.iter_content(chunk_size=1024):
        if chunk:  # filter out keep-alive new chunks
            f.write(chunk)
        if time.time() - start_time > 8:
            raise Exception('Request took longer than 8s')

The solution does not need signals or multiprocessing.

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html

As noted by Riedsio, the session variables do not change after connecting unless you specifically set them; setting the global variable only changes the session value of your next connection.

For example, if you have 100 connections and you lower the global wait_timeout then it will not affect the existing connections, only new ones after the variable was changed.

Specifically for the wait_timeout variable though, there is a twist. If you are using the mysql client in the interactive mode, or the connector with CLIENT_INTERACTIVE set via mysql_real_connect() then you will see the interactive_timeout set for @@session.wait_timeout

Here you can see this demonstrated:

> ./bin/mysql -Bsse 'select @@session.wait_timeout, @@session.interactive_timeout, @@global.wait_timeout, @@global.interactive_timeout' 
70      60      70      60

> ./bin/mysql -Bsse 'select @@wait_timeout'                                                                                                 
70

> ./bin/mysql

After a week of puzzling over this. I think I've figured it out.
I'm now using just an EditText inside of the Toolbar. This was suggested to me by oj88 on reddit.

I now have this:


First inside onCreate() of my activity I added the EditText with an image view on the right hand side to the Toolbar like this:

    // Setup search container view
    searchContainer = new LinearLayout(this);
    Toolbar.LayoutParams containerParams = new Toolbar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    containerParams.gravity = Gravity.CENTER_VERTICAL;
    searchContainer.setLayoutParams(containerParams);

    // Setup search view
    toolbarSearchView = new EditText(this);
    // Set width / height / gravity
    int[] textSizeAttr = new int[]{android.R.attr.actionBarSize};
    int indexOfAttrTextSize = 0;
    TypedArray a = obtainStyledAttributes(new TypedValue().data, textSizeAttr);
    int actionBarHeight = a.getDimensionPixelSize(indexOfAttrTextSize, -1);
    a.recycle();
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, actionBarHeight);
    params.gravity = Gravity.CENTER_VERTICAL;
    params.weight = 1;
    toolbarSearchView.setLayoutParams(params);

    // Setup display
    toolbarSearchView.setBackgroundColor(Color.TRANSPARENT);
    toolbarSearchView.setPadding(2, 0, 0, 0);
    toolbarSearchView.setTextColor(Color.WHITE);
    toolbarSearchView.setGravity(Gravity.CENTER_VERTICAL);
    toolbarSearchView.setSingleLine(true);
    toolbarSearchView.setImeActionLabel("Search", EditorInfo.IME_ACTION_UNSPECIFIED);
    toolbarSearchView.setHint("Search");
    toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
    try {
        // Set cursor colour to white
        // https://stackoverflow.com/a/26544231/1692770
        // https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564
        Field f = TextView.class.getDeclaredField("mCursorDrawableRes");
        f.setAccessible(true);
        f.set(toolbarSearchView, R.drawable.edittext_whitecursor);
    } catch (Exception ignored) {
    }

    // Search text changed listener
    toolbarSearchView.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            Fragment mainFragment = getFragmentManager().findFragmentById(R.id.container);
            if (mainFragment != null && mainFragment instanceof MainListFragment) {
                ((MainListFragment) mainFragment).search(s.toString());
            }
        }

        @Override
        public void afterTextChanged(Editable s) {
            // https://stackoverflow.com/a/6438918/1692770
            if (s.toString().length() <= 0) {
                toolbarSearchView.setHintTextColor(Color.parseColor("#b3ffffff"));
            }
        }
    });
    ((LinearLayout) searchContainer).addView(toolbarSearchView);

    // Setup the clear button
    searchClearButton = new ImageView(this);
    Resources r = getResources();
    int px = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 16, r.getDisplayMetrics());
    LinearLayout.LayoutParams clearParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    clearParams.gravity = Gravity.CENTER;
    searchClearButton.setLayoutParams(clearParams);
    searchClearButton.setImageResource(R.drawable.ic_close_white_24dp); // TODO: Get this image from here: https://github.com/google/material-design-icons
    searchClearButton.setPadding(px, 0, px, 0);
    searchClearButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            toolbarSearchView.setText("");
        }
    });
    ((LinearLayout) searchContainer).addView(searchClearButton);

    // Add search view to toolbar and hide it
    searchContainer.setVisibility(View.GONE);
    toolbar.addView(searchContainer);

This worked, but then I came across an issue where onOptionsItemSelected() wasn't being called when I tapped on the home button. So I wasn't able to cancel the search by pressing the home button. I tried a few different ways of registering the click listener on the home button but they didn't work.

Eventually I found out that the ActionBarDrawerToggle I had was interfering with things, so I removed it. This listener then started working:

    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // toolbarHomeButtonAnimating is a boolean that is initialized as false. It's used to stop the user pressing the home button while it is animating and breaking things.
            if (!toolbarHomeButtonAnimating) {
                // Here you'll want to check if you have a search query set, if you don't then hide the search box.
                // My main fragment handles this stuff, so I call its methods.
                FragmentManager fragmentManager = getFragmentManager();
                final Fragment fragment = fragmentManager.findFragmentById(R.id.container);
                if (fragment != null && fragment instanceof MainListFragment) {
                    if (((MainListFragment) fragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
                        displaySearchView(false);
                        return;
                    }
                }
            }

            if (mDrawerLayout.isDrawerOpen(findViewById(R.id.navigation_drawer)))
                mDrawerLayout.closeDrawer(findViewById(R.id.navigation_drawer));
            else
                mDrawerLayout.openDrawer(findViewById(R.id.navigation_drawer));
        }
    });

So I can now cancel the search with the home button, but I can't press the back button to cancel it yet. So I added this to onBackPressed():

    FragmentManager fragmentManager = getFragmentManager();
    final Fragment mainFragment = fragmentManager.findFragmentById(R.id.container);
    if (mainFragment != null && mainFragment instanceof MainListFragment) {
        if (((MainListFragment) mainFragment).hasSearchQuery() || searchContainer.getVisibility() == View.VISIBLE) {
            displaySearchView(false);
            return;
        }
    }

I created this method to toggle visibility of the EditText and menu item:

public void displaySearchView(boolean visible) {
    if (visible) {
        // Stops user from being able to open drawer while searching
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

        // Hide search button, display EditText
        menu.findItem(R.id.action_search).setVisible(false);
        searchContainer.setVisibility(View.VISIBLE);

        // Animate the home icon to the back arrow
        toggleActionBarIcon(ActionDrawableState.ARROW, mDrawerToggle, true);

        // Shift focus to the search EditText
        toolbarSearchView.requestFocus();

        // Pop up the soft keyboard
        new Handler().postDelayed(new Runnable() {
            public void run() {
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, 0, 0, 0));
                toolbarSearchView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, 0, 0, 0));
            }
        }, 200);
    } else {
        // Allows user to open drawer again
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);

        // Hide the EditText and put the search button back on the Toolbar.
        // This sometimes fails when it isn't postDelayed(), don't know why.
        toolbarSearchView.postDelayed(new Runnable() {
            @Override
            public void run() {
                toolbarSearchView.setText("");
                searchContainer.setVisibility(View.GONE);
                menu.findItem(R.id.action_search).setVisible(true);
            }
        }, 200);

        // Turn the home button back into a drawer icon
        toggleActionBarIcon(ActionDrawableState.BURGER, mDrawerToggle, true);

        // Hide the keyboard because the search box has been hidden
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(toolbarSearchView.getWindowToken(), 0);
    }
}

I needed a way to toggle the home button on the toolbar between the drawer icon and the back button. I eventually found the method below in this SO answer. Though I modified it slightly to made more sense to me:

private enum ActionDrawableState {
    BURGER, ARROW
}

/**
 * Modified version of this, https://stackoverflow.com/a/26836272/1692770<br>
 * I flipped the start offset around for the animations because it seemed like it was the wrong way around to me.<br>
 * I also added a listener to the animation so I can find out when the home button has finished rotating.
 */
private void toggleActionBarIcon(final ActionDrawableState state, final ActionBarDrawerToggle toggle, boolean animate) {
    if (animate) {
        float start = state == ActionDrawableState.BURGER ? 1.0f : 0f;
        float end = Math.abs(start - 1);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            ValueAnimator offsetAnimator = ValueAnimator.ofFloat(start, end);
            offsetAnimator.setDuration(300);
            offsetAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
            offsetAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                @Override
                public void onAnimationUpdate(ValueAnimator animation) {
                    float offset = (Float) animation.getAnimatedValue();
                    toggle.onDrawerSlide(null, offset);
                }
            });
            offsetAnimator.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animation) {

                }

                @Override
                public void onAnimationEnd(Animator animation) {
                    toolbarHomeButtonAnimating = false;
                }

                @Override
                public void onAnimationCancel(Animator animation) {

                }

                @Override
                public void onAnimationRepeat(Animator animation) {

                }
            });
            toolbarHomeButtonAnimating = true;
            offsetAnimator.start();
        }
    } else {
        if (state == ActionDrawableState.BURGER) {
            toggle.onDrawerClosed(null);
        } else {
            toggle.onDrawerOpened(null);
        }
    }
}

This works, I've managed to work out a few bugs that I found along the way. I don't think it's 100% but it works well enough for me.

EDIT: If you want to add the search view in XML instead of Java do this:

There are 2 ways of doing this

foreach($questions as $key => $question){
    $questions[$key]['answers'] = $answers_model->get_answers_by_question_id($question['question_id']);
}

This way you save the key, so you can update it again in the main $questions variable

or

foreach($questions as &$question){

Adding the & will keep the $questions updated. But I would say the first one is recommended even though this is shorter (see comment by Paystey)

Per the PHP foreach documentation:

In order to be able to directly modify array elements within the loop precede $value with &. In that case the value will be assigned by reference.

I had the same problem when trying out Android Studio. I already had projects running on the ADT under SDK 18. No need to hack the manifest files.

Fixed by:

export ANDROID_HOME= pathtobundle/adt-bundle-linux-x86_64-20130729/sdk

If you don't have the ADT installed, and just want the SDK, it seems like a good solution is to install everything and then point Android Studio to the just the packaged SDK.

cd pathtobundle

wget http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20130729.zip

unzip *.zip

As someone else said, you may need to run the SDK Manager to install the desired packages before running Studio.

Semaphore allows multiple threads (up to a set number) to access a shared object. Monitors allow mutually exclusive access to a shared object.

Semaphore

Well one thing you could do is if you have a switch:

switch(SomeEnum)
{
  case SomeEnum.One:
      DoThings(someUser);
      break;
  case SomeEnum.Two:
      DoSomethingElse(someUser);
      break;
}

And with the might power of actions you can turn that switch into a dictionary:

Dictionary<SomeEnum, Action<User>> methodList = 
    new Dictionary<SomeEnum, Action<User>>()

methodList.Add(SomeEnum.One, DoSomething);
methodList.Add(SomeEnum.Two, DoSomethingElse); 

...

methodList[SomeEnum](someUser);

Or you could take this farther:

SomeOtherMethod(Action<User> someMethodToUse, User someUser)
{
    someMethodToUse(someUser);
}  

....

var neededMethod = methodList[SomeEnum];
SomeOtherMethod(neededMethod, someUser);

Just a couple of examples. Of course the more obvious use would be Linq extension methods.

Using the awesome psutil library it's pretty simple:

p = psutil.Process(pid)
p.terminate()  #or p.kill()

If you don't want to install a new library, you can use the os module:

import os
import signal

os.kill(pid, signal.SIGTERM) #or signal.SIGKILL 

See also the os.kill documentation.

If you are interested in starting the command python StripCore.py if it is not running, and killing it otherwise, you can use psutil to do this reliably.

Something like:

import psutil
from subprocess import Popen

for process in psutil.process_iter():
    if process.cmdline() == ['python', 'StripCore.py']:
        print('Process found. Terminating it.')
        process.terminate()
        break
else:
    print('Process not found: starting it.')
    Popen(['python', 'StripCore.py'])

Sample run:

$python test_strip.py   #test_strip.py contains the code above
Process not found: starting it.
$python test_strip.py 
Process found. Terminating it.
$python test_strip.py 
Process not found: starting it.
$killall python
$python test_strip.py 
Process not found: starting it.
$python test_strip.py 
Process found. Terminating it.
$python test_strip.py 
Process not found: starting it.

Note: In previous psutil versions cmdline was an attribute instead of a method.

First of all you have to connect with your database like

my database is ubuntu

use this command to connect

 \c ubuntu

This message will show

"You are now connected to database "ubuntu" as user "postgres"."

Now

Run this command to show all tables in it

\d+

In my case I wanted to tear down the underlying connection in which case I had to call socket.disconnect(true) as you can see is needed from the source here

I had the same problem

The problem is that with Subversion 1.7 this doesn't work anymore. The good news is there is a better way to do this - and what it appears I should have been doing this all along. All you need is:

svn cleanup

found the solution here

MAKE THIS YOUR config.js file code

CKEDITOR.editorConfig = function( config ) {

   //   config.enterMode = 2; //disabled <p> completely
        config.enterMode = CKEDITOR.ENTER_BR // pressing the ENTER KEY input <br/>
        config.shiftEnterMode = CKEDITOR.ENTER_P; //pressing the SHIFT + ENTER KEYS input <p>
        config.autoParagraph = false; // stops automatic insertion of <p> on focus
    };

This is the right CSS3 answer. Hope this helps you somehow now :D I really recommend you to read the book: https://www.amazon.com/Book-CSS3-Developers-Future-Design/dp/1593272863 Actually I have made this solution from reading this book now. :D

You can call the function from code behind like this :

MyForm.aspx.cs

protected void MyButton_Click(object sender, EventArgs e)
{
    Page.ClientScript.RegisterStartupScript(this.GetType(), "myScript", "AnotherFunction();", true);
}

MyForm.aspx

<script type="text/javascript">
    function Test() {
        alert("hi");
        $("#ButtonRow").show();
    }
    function AnotherFunction()
    {
        alert("This is another function");
    }
</script>
</head>
<body>
<form id="form2" runat="server">
<table>
    <tr><td>
            <asp:RadioButtonList ID="SearchCategory" runat="server" onchange="Test()"  RepeatDirection="Horizontal"  BorderStyle="Solid">
               <asp:ListItem>Merchant</asp:ListItem>
               <asp:ListItem>Store</asp:ListItem>
               <asp:ListItem>Terminal</asp:ListItem>
            </asp:RadioButtonList>
        </td>
    </tr>
    <tr id="ButtonRow"style="display:none">
         <td>
            <asp:Button ID="MyButton" runat="server" Text="Click Here" OnClick="MyButton_Click" />
        </td>
    </tr>
    </table> 
</form>

First thing first. set the column in which you are working in by clicking on format cells->number-> date and then format e.g Jan-16 representing Jan, 1, 2016. and then apply either of the formulas above.

A good way to test if a string is a correct date is to use the command date:

if date -d "${DATE}" >/dev/null 2>&1
then
  # do what you need to do with your date
else
  echo "${DATE} incorrect date" >&2
  exit 1
fi

from comment: one can use formatting

if [ "2017-01-14" == $(date -d "2017-01-14" '+%Y-%m-%d') ] 

Thinking of a string as a set of characters, in mathematics the empty set is always a subset of any set.

Highlight the cells, format cells, select Custom then select zero.

A simple alternative is to let the C# environment increment the assembly version for you by setting the version attribute to major.minor.* (as described in the AssemblyInfo file template.)

You may be looking for a more comprehensive solution, though.

EDIT (Response to the question in a comment):

From AssemblyInfo.cs:

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Build and Revision Numbers 
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]

You are calling the ready function before the jQuery JavaScript is included. Reference jQuery first.

On linux (Ubuntu in my case) just install gradle:

sudo apt-get install gradle

Edit: It seems as though ubuntu repo only has gradle 2.10, for newer versions: https://www.vultr.com/docs/how-to-install-gradle-on-ubuntu-16-10

Here's one with extend()

types = ('*.jpg', '*.png')
images_list = []
for files in types:
    images_list.extend(glob.glob(os.path.join(path, files)))

all these annotations are type of stereo type type of annotation,the difference between these three annotations are

• If we add the @Component then it tells the role of class is a component class it means it is a class consisting some logic,but it does not tell whether a class containing a specifically business or persistence or controller logic so we don't use directly this @Component annotation
• If we add @Service annotation then it tells that a role of class consisting business logic
• If we add @Repository on top of class then it tells that a class consisting persistence logic
• Here @Component is a base annotation for @Service,@Repository and @Controller annotations

for example

package com.spring.anno;
@Service
public class TestBean
{
    public void m1()
    {
       //business code
    }
}

package com.spring.anno;
@Repository
public class TestBean
{
    public void update()
    {
       //persistence code
    }
}

• whenever we adds the @Service or @Repositroy or @Controller annotation by default @Component annotation is going to existence on top of the class

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.

Just learning this myself. I will answer the second question:

2. How to use these files? Currently I am using webpack-dev-server to run the application.

Instead of using webpack-dev-server, you can just run an "express". use npm install "express" and create a server.js in the project's root dir, something like this:

var path = require("path");
var express = require("express");

var DIST_DIR = path.join(__dirname, "build");
var PORT = 3000;
var app = express();

//Serving the files on the dist folder
app.use(express.static(DIST_DIR));

//Send index.html when the user access the web
app.get("*", function (req, res) {
  res.sendFile(path.join(DIST_DIR, "index.html"));
});

app.listen(PORT);

Then, in the package.json, add a script:

"start": "node server.js"

Finally, run the app: npm run start to start the server

A detailed example can be seen at: https://alejandronapoles.com/2016/03/12/the-simplest-webpack-and-express-setup/ (the example code is not compatible with the latest packages, but it will work with small tweaks)

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

Compile it like this : gcc demo.c -o demo -pthread

arr.length = n

This might be surprising but length property of an array is not only used to get number of array elements but it's also writable and can be used to set array's length MDN link. This will mutate the array.

If you don't care about immutability or don't want to allocate memory i.e. for a game this will be the fastest way.

to empty an array

arr.length = 0

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

The first answer is almost correct, but what is needed is to change getter method, NOT field -- field is private (and not auto-detected); further, getters have precedence over fields if both are visible.(There are ways to make private fields visible, too, but if you want to have getter there's not much point)

So getter should either be named getWrapper(), or annotated with:

@JsonProperty("wrapper")

If you prefer getter method name as is.

This will work with either an array, an object or a variable and also escapes the special characters that may break your JS :

function debugToConsole($msg) { 
        echo "<script>console.log(".json_encode($msg).")</script>";
}

Edit : Added json_encode to the echo statement. This will prevent your script from breaking if there are quotes in your $msg variable.

You can display an image in your own window using Tkinter, w/o depending on image viewers installed in your system:

import Tkinter as tk
from PIL import Image, ImageTk  # Place this at the end (to avoid any conflicts/errors)

window = tk.Tk()
#window.geometry("500x500") # (optional)    
imagefile = {path_to_your_image_file}
img = ImageTk.PhotoImage(Image.open(imagefile))
lbl = tk.Label(window, image = img).pack()
window.mainloop()

For Python 3, replace import Tkinter as tk with import tkinter as tk.

After few years, I moved to leaflet map and I have fixed this issue completely, the following could be applied to google maps too:

    var headerHeight = $("#navMap").outerHeight();
    var footerHeight = $("footer").outerHeight();
    var windowHeight = window.innerHeight;
    var mapContainerHeight = headerHeight + footerHeight;
    var totalMapHeight = windowHeight - mapContainerHeight;
    $("#map").css("margin-top", headerHeight);
    $("#map").height(totalMapHeight);

    $(window).resize(function(){
        var headerHeight = $("#navMap").outerHeight();
        var footerHeight = $("footer").outerHeight();
        var windowHeight = window.innerHeight;
        var mapContainerHeight = headerHeight + footerHeight;
        var totalMapHeight = windowHeight - mapContainerHeight;
        $("#map").css("margin-top", headerHeight);
        $("#map").height(totalMapHeight);
        map.fitBounds(group1.getBounds());
    });

GC.Collect() 

from MDSN,

Use this method to try to reclaim all memory that is inaccessible.

All objects, regardless of how long they have been in memory, are considered for collection; however, objects that are referenced in managed code are not collected. Use this method to force the system to try to reclaim the maximum amount of available memory.

Try this one

where datediff(month, datetime_column, getdate()) <= 6

To exclude or filter out future dates

where datediff(month, datetime_column, getdate()) between 0 and 6

This part datediff(month, datetime_column, getdate()) will get the month difference in number of current date and Datetime_Column and will return Rows like:

Result
1
2
3
4
5
6
7
8
9
10

This is Our final condition to get last 6 months data

where result <= 6

I solved the same error with the Path.Combine(MapPath()) to get the physical file path instead of the http:/// www one.

Regex is overkill here.

You could use string.Split with the overload that takes a string[] for the delimiters but that would also be overkill.

Look at Substring and IndexOf - the former to get parts of a string given and index and a length and the second for finding indexed of inner strings/characters.

If you are using Java then from the documentation, you can use any one of them based on your use case.

Adding a b prefix would fix the problem.

I always go with the generic css title with my setup. I'm just building analytics for my blog admin page. I don't need anything fancy. Here's some code...

let comps = g.selectAll('.myClass')
   .data(data)
   .enter()
   .append('rect')
   ...styling...
   ...transitions...
   ...whatever...

g.selectAll('.myClass')
   .append('svg:title')
   .text((d, i) => d.name + '-' + i);

And a screenshot of chrome...

If you really need to do it in separate transaction you need to use REQUIRES_NEW and live with the performance overhead. Watch out for dead locks.

I'd rather do it the other way:

• Validate data on Java side.
• Run everyting in one transaction.
• If anything goes wrong on DB side -> it's a major error of DB or validation design. Rollback everything and throw critical top level error.
• Write good unit tests.

I had two issues:

1) My target didn't have the view controller included that was used in the storyboard file.

2) My storyboard was about 3 years old, I had to recreate one of the view controllers in the tab bar controller from scratch (it only had a UITextField and I still don't know why it wasn't working)

This is what I went with. For those of you who want to optimize, check out https://stackoverflow.com/a/624379/991863.

    public static string Hash(string stringToHash)
    {
        using (var sha1 = new SHA1Managed())
        {
            return BitConverter.ToString(sha1.ComputeHash(Encoding.UTF8.GetBytes(stringToHash)));
        }
    }

{{value | number : fractionSize}}

like {{12.52311 | number : 2}}

so this will print 12.52

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

Disclaimer: Rust and Inkscape were chosen because of their size and safety to stay, no advertisement

The most obvious cause of this (included for completeness) is improperly casting a pointer and calling a method of the wrong class.

You're attempting to free something that isn't a pointer to a "freeable" memory address. Just because something is an address doesn't mean that you need to or should free it.

There are two main types of memory you seem to be confusing - stack memory and heap memory.

• Stack memory lives in the live span of the function. It's temporary space for things that shouldn't grow too big. When you call the function main, it sets aside some memory for your variables you've declared (p,token, and so on).

• Heap memory lives from when you malloc it to when you free it. You can use much more heap memory than you can stack memory. You also need to keep track of it - it's not easy like stack memory!

You have a few errors:

• You're trying to free memory that's not heap memory. Don't do that.

• You're trying to free the inside of a block of memory. When you have in fact allocated a block of memory, you can only free it from the pointer returned by malloc. That is to say, only from the beginning of the block. You can't free a portion of the block from the inside.

For your bit of code here, you probably want to find a way to copy relevant portion of memory to somewhere else...say another block of memory you've set aside. Or you can modify the original string if you want (hint: char value 0 is the null terminator and tells functions like printf to stop reading the string).

EDIT: The malloc function does allocate heap memory*.

"9.9.1 The malloc and free Functions

The C standard library provides an explicit allocator known as the malloc package. Programs allocate blocks from the heap by calling the malloc function."

~Computer Systems : A Programmer's Perspective, 2nd Edition, Bryant & O'Hallaron, 2011

EDIT 2: * The C standard does not, in fact, specify anything about the heap or the stack. However, for anyone learning on a relevant desktop/laptop machine, the distinction is probably unnecessary and confusing if anything, especially if you're learning about how your program is stored and executed. When you find yourself working on something like an AVR microcontroller as H2CO3 has, it is definitely worthwhile to note all the differences, which from my own experience with embedded systems, extend well past memory allocation.

One-liner using TestRestTemplate.exchange function with parameters map.

restTemplate.exchange("/someUrl?id={id}", HttpMethod.GET, reqEntity, respType, ["id": id])

The params map initialized like this is a groovy initializer*

To check input type

<!DOCTYPE html>
<html>
<body>

    <input type=number id="txtinp">
    <button onclick=checktype()>Try it</button>

    <script>
        function checktype() 
        {
            alert(document.getElementById("txtinp").type);
        }
    </script>

</body>
</html> 

SELECT COUNT(*) FROM (SELECT * FROM tbl WHERE id=1 UNION SELECT * FROM tbl WHERE id=2) a

If you got two rows, they different, if one - the same.

• CN = Common Name
• OU = Organizational Unit
• DC = Domain Component

These are all parts of the X.500 Directory Specification, which defines nodes in a LDAP directory.

You can also read up on LDAP data Interchange Format (LDIF), which is an alternate format.

You read it from right to left, the right-most component is the root of the tree, and the left most component is the node (or leaf) you want to reach.

Each = pair is a search criteria.

With your example query

("CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com");

In effect the query is:

From the com Domain Component, find the google Domain Component, and then inside it the gl Domain Component and then inside it the gp Domain Component.

In the gp Domain Component, find the Organizational Unit called Distribution Groups and then find the the object that has a common name of Dev-India.

this is what it worked for me I'm using html2pdf from an Angular2 app, so I made a reference to this function in the controller

var html2pdf = (function(html2canvas, jsPDF) {

declared in html2pdf.js.

So I added just after the import declarations in my angular-controller this declaration:

declare function html2pdf(html2canvas, jsPDF): any;

then, from a method of my angular controller I'm calling this function:

generate_pdf(){
    this.someService.loadContent().subscribe(
      pdfContent => {
        html2pdf(pdfContent, {
          margin:       1,
          filename:     'myfile.pdf',
          image:        { type: 'jpeg', quality: 0.98 },
          html2canvas:  { dpi: 192, letterRendering: true },
          jsPDF:        { unit: 'in', format: 'A4', orientation: 'portrait' }
        });
      }
    );
  }

Hope it helps

As Karim said, cross domain ajax doesn't work unless the server allows for it. In this case Google does not, BUT, there is a simple trick to get around this in many cases. Just have your local server pass the content retrieved through HTTP or HTTPS.

For example, if you were using PHP, you could:

Create the file web_root/ajax_responders/google.php with:

<?php
  echo file_get_contents('http://www.google.de');
?>

And then alter your code to connect to that instead of to Google's domain directly in the javascript:

var response = $.ajax({ type: "GET",   
                        url: "/ajax_responders/google.php",   
                        async: false
                      }).responseText;
alert(response);

foreign key (dept_name) references department

This syntax is not valid for MySQL. It should instead be:

foreign key (dept_name) references department(dept_name)

MySQL requires dept_name to be used twice. Once to define the foreign column, and once to define the primary column.

13.1.17.2. Using FOREIGN KEY Constraints

... [the] essential syntax for a foreign key constraint definition in a CREATE TABLE or ALTER TABLE statement looks like this:

[CONSTRAINT [symbol]] FOREIGN KEY
    [index_name] (index_col_name, ...)
    REFERENCES tbl_name (index_col_name, ...)
    [ON DELETE reference_option]
    [ON UPDATE reference_option]

reference_option:
    RESTRICT | CASCADE | SET NULL | NO ACTION

Please note that the problem is not white color. It is because it is being transparent.

When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.

So you cannot say that it is white!

You can place an element above it, and change that element's transparency to 1 while changing the image's transparency to .2 or what so ever you want to.
