It is called closure.

Basically, the function defined within other function is accessible only within this function. But may be passed as a result and then this result may be called.

It is a very powerful feature. You can see more explanation here:

javascript_closures_for_dummies.html mirror on Archive.org

Python 2 didn't have closures - it had workarounds that resembled closures.

There are plenty of examples in answers already given - copying in variables to the inner function, modifying an object on the inner function, etc.

In Python 3, support is more explicit - and succinct:

def closure():
    count = 0
    def inner():
        nonlocal count
        count += 1
        print(count)
    return inner

Usage:

start = closure()
start() # prints 1
start() # prints 2
start() # prints 3

The nonlocal keyword binds the inner function to the outer variable explicitly mentioned, in effect enclosing it. Hence more explicitly a 'closure'.

It's perfectly OK doing it that way, but unless you need to use a closure or return the function I'd probably put in the module level. I imagine in the second code example you mean:

...
some_data = method_b() # not some_data = method_b

otherwise, some_data will be the function.

Having it at the module level will allow other functions to use method_b() and if you're using something like Sphinx (and autodoc) for documentation, it will allow you to document method_b as well.

You also may want to consider just putting the functionality in two methods in a class if you're doing something that can be representable by an object. This contains logic well too if that's all you're looking for.

Thanks for the idea of breaking down a formula Werner!

Using Alt+Enter allows one to put each bit of a complex substitute formula on separate lines: they become easier to follow and automatically line themselves up when Enter is pressed.

Just make sure you have enough end statements to match the number of substitute( lines either side of the cell reference.

As in this example:

=
substitute(
substitute(
substitute(
substitute(
B11
,"(","")
,")","")
,"[","")
,"]","")

becomes:

=
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

which works fine as is, but one can always delete the extra paragraphs manually:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

Name > substitute()

[American Samoa] > American Samoa

A simple way to achieve this is the negative set [^\w\s]. This essentially catches:

• Anything that is not an alphanumeric character (letters and numbers)
• Anything that is not a space, tab, or line break (collectively referred to as whitespace)

For some reason [\W\S] does not work the same way, it doesn't do any filtering. A comment by Zael on one of the answers provides something of an explanation.

using (var context = new DataDb())
{
     var ctx = ((System.Data.Entity.Infrastructure.IObjectContextAdapter)context).ObjectContext;
     ctx.ExecuteStoreCommand("DELETE FROM [TableName] WHERE Name= {0}", Name);
}

or

using (var context = new DataDb())
{
     context.Database.ExecuteSqlCommand("TRUNCATE TABLE [TableName]");
}

This avoids your problem rather than fixing it directly, but I'd recommend adding a ~/.ssh/config file and having something like this

Host git_host
HostName git.host.de
User root
Port 4019

then you can have

url = git_host:/var/cache/git/project.git

and you can also ssh git_host and scp git_host ... and everything will work out.

You're performing an integer division. Append a .0 to the number literals:

per=float(tota)*(100.0/500.0)

In Python 2.7 the division 100/500==0.

As pointed out by @unwind, the float() call is superfluous since a multiplication/division by a float returns a float:

per= tota*100.0 / 500

I had moved my log4j.properties into the resources folder and it worked fine for me !

You could use this jQuery plugin waitForImage or you could put you images into an hidden div or (width:0 and height:0) and use onload event on images.

If you only have like 2-3 images you can bind events and trigger them in a chain so after every image you can do some code.

I ran into a similar problem. I'm using spring boot 2.x and I missed to add Postgres dependency at spring initializer. I added the dependency manually

<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<scope>runtime</scope>
</dependency>

and here is what I was getting- INFO org.hibernate.dialect.Dialect - HHH000400: Using dialect: org.hibernate.dialect.PostgreSQLDialect instead of

**INFO  org.hibernate.dialect.Dialect - HHH000400: Using 
dialect:org.hibernate.dialect.PostgreSQL10Dialect**

This connected me to the DB

It's not so weird because Springboot does version dependency by itself and reduces the development work. On the flip side, if Springboot chooses incorrect dependency, it wastes a lot many hours.

SELECT d1.Short_Code

Try Following

I wrote a simple wrapper around Google's .Net client library, it exposes a simpler database-like interface, with strongly-typed record types. Here's some sample code:

public class Entity {
    public int IntProp { get; set; }
    public string StringProp { get; set; }
}

var e1 = new Entity { IntProp = 2 };
var e2 = new Entity { StringProp = "hello" };
var client = new DatabaseClient("[email protected]", "password");
const string dbName = "IntegrationTests";
Console.WriteLine("Opening or creating database");
db = client.GetDatabase(dbName) ?? client.CreateDatabase(dbName); // databases are spreadsheets
const string tableName = "IntegrationTests";
Console.WriteLine("Opening or creating table");
table = db.GetTable<Entity>(tableName) ?? db.CreateTable<Entity>(tableName); // tables are worksheets
table.DeleteAll();
table.Add(e1);
table.Add(e2);
var r1 = table.Get(1);

There's also a LINQ provider that translates to google's structured query operators:

var q = from r in table.AsQueryable()
        where r.IntProp > -1000 && r.StringProp == "hello"
        orderby r.IntProp
        select r;

You could make a batch file with the following code:

start javaw -jar JarFile.jar

and convert the .bat to an .exe using any .bat to .exe converter.

This way you only need to free the structure because the fields are arrays with static sizes which will be allocated as part of the structure. This is also the reason that the addresses you see match: the array is the first thing in that structure. If you declared the fields as char * you would have to manually malloc and free them as well.

If you're using # as an operator, consider defining a new operator for it:

\newcommand{\pound}{\operatornamewithlimits{\#}}

You can then write things like \pound_{n = 1}^N and get:

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

I tried this command to display the list of files in the directory.

dir /s /b > List.txt

In the file it displays the list below.

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppMgr.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppSDK.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Plantronics

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\SennheiserJabberPlugin.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll

What is want to do is only to display sub-directory not the full directory path.

Just like this:

Cisco Jabber\XmppMgr.dll Cisco Jabber\XmppSDK.dll

Cisco Jabber\accessories\JabraJabberPlugin.dll

Cisco Jabber\accessories\Logitech

Cisco Jabber\accessories\Plantronics

Cisco Jabber\accessories\SennheiserJabberPlugin.dll

I realize this has been finished, but you may want to look at strncmp as it allows you to put the length of the string to compare against, so:

function startsWith($haystack, $needle, $case=true) {
    if ($case)
        return strncasecmp($haystack, $needle, strlen($needle)) == 0;
    else
        return strncmp($haystack, $needle, strlen($needle)) == 0;
}    

If you are using this form of the branch command (with start point), it does not matter where your HEAD is.

What you are doing:

git checkout dev
git branch test 07aeec983bfc17c25f0b0a7c1d47da8e35df7af8

• First, you set your HEAD to the branch dev,

• Second, you start a new branch on commit 07aeec98. There is no bb.txt at this commit (according to your github repo).

If you want to start a new branch at the location you have just checked out, you can either run branch with no start point:

git branch test

or as other have answered, branch and checkout there in one operation:

git checkout -b test

I think that you might be confused by that fact that 07aeec98 is part of the branch dev. It is true that this commit is an ancestor of dev, its changes are needed to reach the latest commit in dev. However, they are other commits that are needed to reach the latest dev, and these are not necessarily in the history of 07aeec98.

8480e8ae (where you added bb.txt) is for example not in the history of 07aeec98. If you branch from 07aeec98, you won't get the changes introduced by 8480e8ae.

In other words: if you merge branch A and branch B into branch C, then create a new branch on a commit of A, you won't get the changes introduced in B.

Same here, you had two parallel branches master and dev, which you merged in dev. Branching out from a commit of master (older than the merge) won't provide you with the changes of dev.

If you want to permanently integrate new changes from master into your feature branches, you should merge master into them and go on. This will create merge commits in your feature branches, though.

If you have not published your feature branches, you can also rebase them on the updated master: git rebase master featureA. Be prepared to solve possible conflicts.

If you want a workflow where you can work on feature branches free of merge commits and still integrate with newer changes in master, I recommend the following:

• base every new feature branch on a commit of master
• create a dev branch on a commit of master
• when you need to see how your feature branch integrates with new changes in master, merge both master and the feature branch into dev.

Do not commit into dev directly, use it only for merging other branches.

For example, if you are working on feature A and B:

a---b---c---d---e---f---g -master
    \       \
     \       \-x -featureB
      \
       \-j---k -featureA

Merge branches into a dev branch to check if they work well with the new master:

a---b---c---d---e---f---g -master
    \       \            \
     \       \            \--x'---k' -dev
      \       \             /    /   
       \       \-x----------    /    -featureB
        \                      /
         \-j---k--------------- -featureA

You can continue working on your feature branches, and keep merging in new changes from both master and feature branches into dev regularly.

a---b---c---d---e---f---g---h---i----- -master
    \       \            \            \
     \       \            \--x'---k'---i'---l' -dev
      \       \             /    /         /
       \       \-x----------    /         /  -featureB
        \                      /         /  
         \-j---k-----------------l------ -featureA

When it is time to integrate the new features, merge the feature branches (not dev!) into master.

Did you write

String guid = System.Guid.NewGuid().ToString;

or

String guid = System.Guid.NewGuid().ToString();

notice the paranthesis

I had a similar problem and none of the solutions above worked, so I went with an old standby that always works:

1. Rename the folder containing the project
2. Make a brand new project with the same name with 2010
3. Diff the two folders and->
4. Copy all source files directly
5. Ignore bin/debug/release etc
6. Diff the .csproj and copy over all lines that are relevant.
7. If the .sln file only has one project, ignore it. If it's complex, then diff it as well.

That almost always works if you've spent 10 minutes at it and can't get it.

Note that for similar problems with older versions (2008, 2005) you can usually get away with just changing the version in the .csproj and either changing the version in the .sln or discarding it, but this doesn't seem to work for 2013.

Selects are slow and unnescsaary. The following code will be far faster:

Sub CopyRowsAcross() 
Dim i As Integer 
Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Sheets("Sheet1") 
Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Sheets("Sheet2") 

For i = 2 To ws1.Range("B65536").End(xlUp).Row 
    If ws1.Cells(i, 2) = "Your Critera" Then ws1.Rows(i).Copy ws2.Rows(ws2.Cells(ws2.Rows.Count, 2).End(xlUp).Row + 1) 
Next i 
End Sub

If you are on SQL Server 2008 you can also use

 CRYPT_GEN_RANDOM(2) % 10000

Which seems somewhat simpler (it is also evaluated once per row as newid is - shown below)

DECLARE @foo TABLE (col1 FLOAT)

INSERT INTO @foo SELECT 1 UNION SELECT 2

UPDATE @foo
SET col1 =  CRYPT_GEN_RANDOM(2) % 10000

SELECT *  FROM @foo

Returns (2 random probably different numbers)

col1
----------------------
9693
8573

Mulling the unexplained downvote the only legitimate reason I can think of is that because the random number generated is between 0-65535 which is not evenly divisible by 10,000 some numbers will be slightly over represented. A way around this would be to wrap it in a scalar UDF that throws away any number over 60,000 and calls itself recursively to get a replacement number.

CREATE FUNCTION dbo.RandomNumber()
RETURNS INT
AS
  BEGIN
      DECLARE @Result INT

      SET @Result = CRYPT_GEN_RANDOM(2)

      RETURN CASE
               WHEN @Result < 60000
                     OR @@NESTLEVEL = 32 THEN @Result % 10000
               ELSE dbo.RandomNumber()
             END
  END  

Minor note: since Java 1.7 the Integer class has a static compare(Integer, Integer) method, so you can just call Integer.compare(x, y) and be done with it (questions about optimization aside).

Of course that code is incompatible with versions of Java before 1.7, so I would recommend using x.compareTo(y) instead, which is compatible back to 1.2.

     foreach (DataRow row in dt.Rows) 
     {
        foreach (DataColumn col in dt.Columns)
           Console.WriteLine(row[col]);
     }

In your model,

class Contact
  self.email_providers = %w[Gmail Yahoo MSN]
  validates :email_provider, :inclusion => email_providers
end

In your form,

<%= f.select :email_provider, 
    options_for_select(Contact.email_providers, @contact.email_provider) %>

the second arg of the options_for_select will have any current email_provider selected.

class App():
    def __init__(self):
        self.root = Tkinter.Tk()
        button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()

app = App()

Using JQuery you can do the following:

// for the element which uses ID
$("#id").trigger("change");

// for the element which uses class name
$(".class_name").trigger("change");

You can either do 1 of the following:

Change:

SET @UserId = 0 to SELECT @UserId

This will return the value in the same way your 2nd part of the IF statement is.

Or, seeing as @UserId is set as an Output, change:

SELECT SCOPE_IDENTITY() to SET @UserId = SCOPE_IDENTITY()

It depends on how you want to access the data afterwards. If you want the value to be in your result set, use SELECT. If you want to access the new value of the @UserId parameter afterwards, then use SET @UserId

Seeing as you're accepting the 2nd condition as correct, the query you could write (without having to change anything outside of this query) is:

@EmailAddress varchar(200),
@NickName varchar(100),
@Password varchar(150),
@Sex varchar(50),
@Age int,
@EmailUpdates int,
@UserId int OUTPUT
IF 
    (SELECT COUNT(UserId) FROM RegUsers WHERE EmailAddress = @EmailAddress) > 0
    BEGIN
        SELECT 0
    END
ELSE
    BEGIN
        INSERT INTO RegUsers (EmailAddress,NickName,PassWord,Sex,Age,EmailUpdates) VALUES (@EmailAddress,@NickName,@Password,@Sex,@Age,@EmailUpdates)
        SELECT SCOPE_IDENTITY()
    END

END

After years of using XAMPP finally I've given up, and started looking for alternatives. XAMPP has not received any updates for quite a while and it kept breaking down once every two weeks.

The one I've just found and I could absolutely recommend is The Uniform Server

It's really frequently updated, has much more emphasis on security and looks like a much more mature project compared to XAMPP.

They have a wiki where they list all the latest versions of packages. As the time of writing, their newest release is only 4 days old!

Versions in Uniform Server as of today:

• Apache 2.4.2
• MySQL 5.5.23-community
• PHP 5.4.1
• phpMyAdmin 3.5.0

Versions in XAMPP as of today:

• Apache 2.2.21
• MySQL 5.5.16
• PHP 5.3.8
• phpMyAdmin 3.4.5

I wrote a library for solving this problem, everything happens in compiling time, except for getting the message.

Usage:

Use macro DEF_MSG to define a macro and message pair:

DEF_MSG(CODE_OK,   "OK!")
DEF_MSG(CODE_FAIL, "Fail!")

CODE_OK is the macro to use, and "OK!" is the corresponding message.

Use get_message() or just gm() to get the message:

get_message(CODE_FAIL);  // will return "Fail!"
gm(CODE_FAIL);           // works exactly the same as above

Use MSG_NUM to find out how many macros have been defined. This will automatically increse, you don't need to do anything.

Predefined messages:

MSG_OK:     OK
MSG_BOTTOM: Message bottom

Project: libcodemsg

The library doesn't create extra data. Everything happens in compiling time. In message_def.h, it generates an enum called MSG_CODE; in message_def.c, it generates a variable holds all the strings in static const char* _g_messages[].

In such case, the library is limited to create one enum only. This is ideal for return values, for example:

MSG_CODE foo(void) {
    return MSG_OK; // or something else
}

MSG_CODE ret = foo();

if (MSG_OK != ret) {
    printf("%s\n", gm(ret););
}

Another thing I like this design is you can manage message definitions in different files.

I found the solution to this question looks much better.

If the URL that you are trying to remove the query string from is the current URL of the PHP script, you can use one of the previously mentioned methods. If you just have a string variable with a URL in it and you want to strip off everything past the '?' you can do:

$pos = strpos($url, "?");
$url = substr($url, 0, $pos);

Use:

dir -Directory -Recurse | Select FullName

This will give you an output of the root structure with the folder name for directories only.

I think you want to specify

-H "Content-Type:text/xml"

with a colon, not an equals.

If you want a "editable grid" i.e. a table like structure that allows you to make any of the rows a form, use CSS that mimics the TABLE tag's layout: display:table, display:table-row, and display:table-cell.

There is no need to wrap your whole table in a form and no need to create a separate form and table for each apparent row of your table.

Try this instead:

<style>
DIV.table 
{
    display:table;
}
FORM.tr, DIV.tr
{
    display:table-row;
}
SPAN.td
{
    display:table-cell;
}
</style>
...
<div class="table">
    <form class="tr" method="post" action="blah.html">
        <span class="td"><input type="text"/></span>
        <span class="td"><input type="text"/></span>
    </form>
    <div class="tr">
        <span class="td">(cell data)</span>
        <span class="td">(cell data)</span>
    </div>
    ...
</div>

The problem with wrapping the whole TABLE in a FORM is that any and all form elements will be sent on submit (maybe that is desired but probably not). This method allows you to define a form for each "row" and send only that row of data on submit.

The problem with wrapping a FORM tag around a TR tag (or TR around a FORM) is that it's invalid HTML. The FORM will still allow submit as usual but at this point the DOM is broken. Note: Try getting the child elements of your FORM or TR with JavaScript, it can lead to unexpected results.

Note that IE7 doesn't support these CSS table styles and IE8 will need a doctype declaration to get it into "standards" mode: (try this one or something equivalent)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Any other browser that supports display:table, display:table-row and display:table-cell should display your css data table the same as it would if you were using the TABLE, TR and TD tags. Most of them do.

Note that you can also mimic THEAD, TBODY, TFOOT by wrapping your row groups in another DIV with display: table-header-group, table-row-group and table-footer-group respectively.

NOTE: The only thing you cannot do with this method is colspan.

Check out this illustration: http://jsfiddle.net/ZRQPP/

You will need to have a datetime column in a table. Then you can do an insert like the following to insert the current date:

INSERT INTO MyTable (MyDate) Values (GetDate())

If it is not today's date then you should be able to use a string and specify the date format:

INSERT INTO MyTable (MyDate) Values (Convert(DateTime,'19820626',112)) --6/26/1982

You do not always need to convert the string either, often you can just do something like:

INSERT INTO MyTable (MyDate) Values ('06/26/1982') 

And SQL Server will figure it out for you.

Best practice is to use Android Support Library version 26.0.0 or above.

STEP 1: add font file

1. In res folder create new font resource dictionary
2. Add font file (.ttf, .orf)

For example, when font file will be helvetica_neue.ttf that will generates R.font.helvetica_neue

STEP 2: create font family

1. In font folder add new resource file
2. Enclose each font file, style, and weight attribute in the element.

For example:

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android">
    <font
        android:fontStyle="normal"
        android:fontWeight="400"
        android:font="@font/helvetica_neue" />
</font-family>

STEP 3: use it

In xml layouts:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fontFamily="@font/my_font"/>

Or add fonts to style:

<style name="customfontstyle" parent="@android:style/TextAppearance.Small">
    <item name="android:fontFamily">@font/lobster</item>
</style>

For more examples you can follow documentation:

Working with fonts

There are two main reasons why you can use an atomic boolean. First its mutable, you can pass it in as a reference and change the value that is a associated to the boolean itself, for example.

public final class MyThreadSafeClass{

    private AtomicBoolean myBoolean = new AtomicBoolean(false);
    private SomeThreadSafeObject someObject = new SomeThreadSafeObject();

    public boolean doSomething(){
         someObject.doSomeWork(myBoolean);
         return myBoolean.get(); //will return true
    }
}

and in the someObject class

public final class SomeThreadSafeObject{
    public void doSomeWork(AtomicBoolean b){
        b.set(true);
    }
}

More importantly though, its thread safe and can indicate to developers maintaining the class, that this variable is expected to be modified and read from multiple threads. If you do not use an AtomicBoolean you must synchronize the boolean variable you are using by declaring it volatile or synchronizing around the read and write of the field.

I've found a solution. If you want to update razor version or mvc 4 to 5, change some lines.

Old code in Views/web.config

<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
  <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
  <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>

Replaced with

<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
    <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>

sectionGroup must be change, too.

I don't know if leaving hibernate off the front makes a difference.

The reference suggests it should be hibernate.hbm2ddl.auto

A value of create will create your tables at sessionFactory creation, and leave them intact.

A value of create-drop will create your tables, and then drop them when you close the sessionFactory.

Perhaps you should set the javax.persistence.Table annotation explicitly?

Hope this helps.

I use Strongloop's cli tools for that; see https://strongloop.com/strongblog/switch-between-configure-public-and-private-npm-registry/ for more information

Switching between repositories is as easy as : slc registry use <name>

This Works well

jQuery('.id_100').change(function(){ 
        var value = jQuery('.id_100').val(); //it gets you the value of selected option 
        console.log(value); // you can see your sected values in console, Eg 1,2,3
    });

Use ver it will list all the installed toolboxes and versions of the toolbox.

Following will give you active connections/ queries in postgres DB-

SELECT 
    pid
    ,datname
    ,usename
    ,application_name
    ,client_hostname
    ,client_port
    ,backend_start
    ,query_start
    ,query
    ,state
FROM pg_stat_activity
WHERE state = 'active';

You may use 'idle' instead of active to get already executed connections/queries.

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

Not an equivalent, but you can use a Scanner and a pattern to parse lines with three non-negative numbers separated by spaces, for example:

71 5796 2489
88 1136 5298
42 420 842

Here's the code using findAll:

new Scanner(System.in).findAll("(\\d+) (\\d+) (\\d+)")
        .forEach(result -> {
            int fst = Integer.parseInt(result.group(1));
            int snd = Integer.parseInt(result.group(2));
            int third = Integer.parseInt(result.group(3));
            int sum = fst + snd + third;
            System.out.printf("%d + %d + %d = %d", fst, snd, third, sum);
        });

Basically,

DTO: "Data transfer objects " can travel between seperate layers in software architecture.

VO: "Value objects " hold a object such as Integer,Money etc.

POJO: Plain Old Java Object which is not a special object.

Java Beans: requires a Java Class to be serializable, have a no-arg constructor and a getter and setter for each field

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

int wantedPosition = 25; // Whatever position you're looking for
int firstPosition = linearLayoutManager.findFirstVisibleItemPosition(); // This is the same as child #0
int wantedChild = wantedPosition - firstPosition;

if (wantedChild < 0 || wantedChild >= linearLayoutManager.getChildCount()) {
    Log.w(TAG, "Unable to get view for desired position, because it's not being displayed on screen.");
    return;
}

View wantedView = linearLayoutManager.getChildAt(wantedChild);
mlayoutOver =(LinearLayout)wantedView.findViewById(R.id.layout_over);
mlayoutPopup = (LinearLayout)wantedView.findViewById(R.id.layout_popup);

mlayoutOver.setVisibility(View.INVISIBLE);
mlayoutPopup.setVisibility(View.VISIBLE);

For RecycleView please use this code

You need to use the __getitem__ method.

class MyClass:
    def __getitem__(self, key):
        return key * 2

myobj = MyClass()
myobj[3] #Output: 6

And if you're going to be setting values you'll need to implement the __setitem__ method too, otherwise this will happen:

>>> myobj[5] = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: MyClass instance has no attribute '__setitem__'

As quick n dirty fix, this worked for me: Adding this 2 lines before the problematic import:

import sys
sys.path.append('C:\\Python27\\Lib\site-packages')

When creating the colors, you may use rgb and set its alpha argument:

plot(1:10, col = rgb(red = 1, green = 0, blue = 0, alpha = 0.5),
     pch = 16, cex = 4)
points((1:10) + 0.4, col = rgb(red = 0, green = 0, blue = 1, alpha = 0.5),
       pch = 16, cex = 4)

Please see ?rgb for details.

I got this when installing a library using anaconda. My version went from Python 3.* to 2.7 and a lot of my stuff stopped working. The best solution I found was to first see the most recent version available:

conda search python

Then update to the version you want:

conda install python=3.*.*

Source: http://chris35wills.github.io/conda_python_version/

Other helpful commands:

conda info
python --version

You should put your model class before create_all() call, like this:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True)
    email = db.Column(db.String(120), unique=True)

    def __init__(self, username, email):
        self.username = username
        self.email = email

    def __repr__(self):
        return '<User %r>' % self.username

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

If your models are declared in a separate module, import them before calling create_all().

Say, the User model is in a file called models.py,

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)

# See important note below
from models import User

db.create_all()
db.session.commit()

admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users

Important note: It is important that you import your models after initializing the db object since, in your models.py _you also need to import the db object from this module.

The syntax you have used is incorrect. The query should be something like:

SELECT column_name(s) FROM tablename WHERE id = (SELECT MAX(id) FROM tablename)

Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?

There is

I used this blog post to install it in my machine: http://luminite.wordpress.com/2012/09/06/installing-oracle-database-xe-11g-on-windows-7-64-bit-machine/

The only thing you have to do is replace a registry value during the installation, I've done it about three times already, and every time found a different reference on-line, none here on stackoverflow.

EDIT: as @kc2001 noted, regedit must be run as Administrator, and added this tutorial: (a bit more colorful): http://www.hanmiaojuan.com/2013/03/install-oracle-xe-11g-for-windows7-64bits.html

• Goto http://buildtry.com

• Upload .ipa (iOS) or .apk (Android) file

• Copy and Share the link with testers

• Open the link in iOS or Android device browser and click Install

Call the TreeView.OnAfterSelect() protected method after you programatically select the node.

This article by Andre Staltz is the best and clearest explanation I've seen so far.

Some quotes from the article:

Reactive programming is programming with asynchronous data streams.

On top of that, you are given an amazing toolbox of functions to combine, create and filter any of those streams.

Here's an example of the fantastic diagrams that are a part of the article:

To add to the above correct answer :- For my case in shell, this code worked (working on sqoop)

ROOT_PATH="path/to/the/folder"
--options-file  $ROOT_PATH/query.txt

Alternatively, you may also use the CSS3 Flexible Box Model. It's a great way to create flexible layouts that can also be applied to center content like so:

#parent {
    -webkit-box-align:center;
    -webkit-box-pack:center;
    display:-webkit-box;
}

Your best bet is to use one of the latest versions of Eclipse (I am using Eclipse Galileo J2EE and Eclipse Ganymede J2EE). Create a JavaScript file, then create a variable:

var jsonObject = {"menu": {"id": "file","value": "File","popup": {"menuitem": [{"value": "New", "onclick": "CreateNewDoc()"},{"value": "Open", "onclick": "OpenDoc()"},{"value": "Close", "onclick": "CloseDoc()"}]}}};

Lastly, hit CTRL+SHIFT+F and voila! You have a nicely indented JSON Object. I, too, am looking for a Notepad++ JSON formatter, and I very well may be forced to develop an Npp plugin some short time in the future.

I also had the same problem while accessing RESTful web services. And I their with the below code to overcome the issue:

public class Test {
    //Bypassing the SSL verification to execute our code successfully 
    static {
        disableSSLVerification();
    }

    public static void main(String[] args) {    
        //Access HTTPS URL and do something    
    }
    //Method used for bypassing SSL verification
    public static void disableSSLVerification() {

        TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }

        } };

        SSLContext sc = null;
        try {
            sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
        } catch (KeyManagementException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };      
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);           
    }
}

It worked for me. try it!!

The biggest problem I ran into doing this was cases like "Bob R. Smith, Jr.". The algorithm I used is posted at http://www.blackbeltcoder.com/Articles/strings/splitting-a-name-into-first-and-last-names. My code is in C# but you could port it if you must have in SQL.

If your administrator changed your password, and Windows 10 still stores your old password you will not be asked for a new password. Windows 10 will use the stored old password, and authentication will fail.

You can delete your old password by

1. Click Start > Control Panel > User Accounts > Manage your credentials
2. Windows credentials
3. Modify or delete the stored password

If you delete a password, when you try to use SVN, you will be asked for the new password.

Here is my solution:

<!-- jquery smooth scroll to id's -->   
<script>
$(function() {
  $('a[href*=\\#]:not([href=\\#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 500);
        return false;
      }
    }
  });
});
</script>

With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.

I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)

For clarifications, let me know. Hope it helps!

When importing an existing Gradle project (one with a build.gradle) into IntelliJ IDEA, when presented with the following screen, select Import from external model -> Gradle.

Optionally, select Auto Import on the next screen to automatically import new dependencies.

It is a very sensitive point to understand how to work System.out.print. If the first element is String then plus(+) operator works as String concate operator. If the first element is integer plus(+) operator works as mathematical operator.

public static void main(String args[]) {
    System.out.println("String" + 8 + 8); //String88
    System.out.println(8 + 8+ "String"); //16String
}

Another way of doing this is using nested IF statements. Suppose you have companies table and you want to count number of records in it. A sample query would be something like this

SELECT IF(
      count(*) > 15,
      'good',
      IF(
          count(*) > 10,
          'average',
          'poor'
        ) 
      ) as data_count 
      FROM companies

Here second IF condition works when the first IF condition fails. So Sample Syntax of the IF statement would be IF ( CONDITION, THEN, ELSE). Hope it helps someone.

Here is a code sample:

var dataset = entities.processlists
    .Where(x => x.environmentID == environmentid && x.ProcessName == processname && x.RemoteIP == remoteip && x.CommandLine == commandlinepart)
    .Select(x => new PInfo 
                 { 
                      ServerName = x.ServerName, 
                      ProcessID = x.ProcessID, 
                      UserName = x.Username 
                 }) AsEnumerable().
               Select(y => new PInfo
               {
                   ServerName = y.ServerName,
                   ProcessID = y.ProcessID,
                   UserName = y.UserName 
               }).ToList();

If you use json_decode($string, true), you will get no objects, but everything as an associative or number indexed array. Way easier to handle, as the stdObject provided by PHP is nothing but a dumb container with public properties, which cannot be extended with your own functionality.

$array = json_decode($string, true);

echo $array['trends'][0]['name'];

You can always JQuery-ize your form.submit, but it may just call the same thing:

$("form").submit(); // probably able to affect multiple forms (good or bad)

// or you can address it by ID
$("#yourFormId").submit();

You can also attach functions to the submit event, but that is a different concept.

On my mac:

info diff then select: Output formats -> Context -> Unified format -> Detailed Unified :

Or online man diff on gnu following the same path to the same section:

File: diff.info, Node: Detailed Unified, Next: Example Unified, Up: Unified Format

Detailed Description of Unified Format ......................................

The unified output format starts with a two-line header, which looks like this:

 --- FROM-FILE FROM-FILE-MODIFICATION-TIME
 +++ TO-FILE TO-FILE-MODIFICATION-TIME

The time stamp looks like `2002-02-21 23:30:39.942229878 -0800' to indicate the date, time with fractional seconds, and time zone.

You can change the header's content with the `--label=LABEL' option; see *Note Alternate Names::.

Next come one or more hunks of differences; each hunk shows one area where the files differ. Unified format hunks look like this:

 @@ FROM-FILE-RANGE TO-FILE-RANGE @@
  LINE-FROM-EITHER-FILE
  LINE-FROM-EITHER-FILE...

The lines common to both files begin with a space character. The lines that actually differ between the two files have one of the following indicator characters in the left print column:

`+' A line was added here to the first file.

`-' A line was removed here from the first file.

If, like me, you are trying to use GETDATE() within an expression and have the seemingly unreasonable requirement (SSIS/SSDT seems very much a work in progress to me, and not a polished offering) of wanting that date to get inserted into SQL Server as a valid date (type = datetime), then I found this expression to work:

@[User::someVar] = (DT_WSTR,4)YEAR(GETDATE()) + "-"  + RIGHT("0" + (DT_WSTR,2)MONTH(GETDATE()), 2) + "-"  + RIGHT("0" + (DT_WSTR,2)DAY( GETDATE()), 2) + " " + RIGHT("0" + (DT_WSTR,2)DATEPART("hh", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("mi", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("ss", GETDATE()), 2)

I found this code snippet HERE

The answer provided by Matt Lacey works for Windows XP. However, in Windows Server 2003 the line

 tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log

returns

INFO: No tasks are running which match the specified criteria.

which is then read as the process is running.

I don't have a heap of batch scripting experience, so my soulution is to then search for the process name in the search.log file and pump the results into another file and search that for any output.

tasklist /FI "IMAGENAME eq notepad.exe" /FO CSV > search.log

FINDSTR notepad.exe search.log > found.log

FOR /F %%A IN (found.log) DO IF %%~zA EQU 0 GOTO end

start notepad.exe

:end

del search.log
del found.log

I hope this helps someone else.

send an output parameter like

@newId int output

at the end use

    select @newId = Scope_Identity() 

     return @newId 

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
{
    if(e.Button == MouseButtons.Right)
    {
        MyDataGridView.ClearSelection();
        MyDataGridView.Rows[e.RowIndex].Selected = true;
    }
}

private void DeleteRow_Click(object sender, EventArgs e)
{
    Int32 rowToDelete = MyrDataGridView.Rows.GetFirstRow(DataGridViewElementStates.Selected);
    MyDataGridView.Rows.RemoveAt(rowToDelete);
    MyDataGridView.ClearSelection();
}

You can display it like this:

var strOriginal = richTextBox1.Text;

byte[] byt = System.Text.Encoding.ASCII.GetBytes(strOriginal);

// convert the byte array to a Base64 string
string strModified = Convert.ToBase64String(byt);

richTextBox1.Text = "" + strModified;

Now, converting it back.

var base64EncodedBytes = System.Convert.FromBase64String(richTextBox1.Text);

richTextBox1.Text = "" + System.Text.Encoding.ASCII.GetString(base64EncodedBytes);
MessageBox.Show("Done Converting! (ASCII from base64)");

I hope this helps!

You are setting your cron to run on 10th minute in every hour.
To set it to every 5 mins change to */5 * * * * /usr/bin/php /mydomain.in/cronmail.php > /dev/null 2>&1

Here is my shortest solution:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something after 100ms
    }
}, 100);

If you're OK with using a library that writes the SQL for you, then you can use Upsert (currently Ruby and Python only):

Pet.upsert({:name => 'Jerry'}, :breed => 'beagle')
Pet.upsert({:name => 'Jerry'}, :color => 'brown')

That works across MySQL, Postgres, and SQLite3.

It writes a stored procedure or user-defined function (UDF) in MySQL and Postgres. It uses INSERT OR REPLACE in SQLite3.

Here's how you can do it all in one line:

df[['a', 'b']].fillna(value=0, inplace=True)

Breakdown: df[['a', 'b']] selects the columns you want to fill NaN values for, value=0 tells it to fill NaNs with zero, and inplace=True will make the changes permanent, without having to make a copy of the object.

Alternatively,

<style type="text/css">
#example {
    display: block;
    width: 30px;
    height: 10px;
    background: url(../images/example.png) no-repeat;
    text-indent: -9999px;
}
</style>

<a href="http://www.example.com" id="example">See an example!</a>

More wordy, but it may benefit SEO, and it will look like nice simple text with CSS disabled.

there are two options to solve this issue

option number 1 : use certificate with less length RSA 2048

option number 2 : you will update two jars in jre\lib\security whatever you use java http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html

or you use IBM websphere or any application server that use its java . the main problem that i faced i used certification with maximum length ,when i deployed ears on websphere the same exception is thrown

Java Security: Illegal key size or default parameters?

i updated java intsalled folder in websphere with two jars https://www14.software.ibm.com/webapp/iwm/web/reg/pick.do?source=jcesdk&lang=en_US

you can check reference in link https://www-01.ibm.com/support/docview.wss?uid=swg21663373

compileSdkVersion : The compileSdkVersion is the version of the API the app is compiled against. This means you can use Android API features included in that version of the API (as well as all previous versions, obviously). If you try and use API 16 features but set compileSdkVersion to 15, you will get a compilation error. If you set compileSdkVersion to 16 you can still run the app on a API 15 device.

minSdkVersion : The min sdk version is the minimum version of the Android operating system required to run your application.

targetSdkVersion : The target sdk version is the version your app is targeted to run on.

Here's another CSS only solution that works with any HTML layout.

It works with any element you need to switch. Whatever your toggle layout is you just put it inside a couple of elements with the if-collapsed and if-not-collapsed classes inside the toggle element.

The only catch is that you have to make sure you put the desired initial state of the toggle. If it's initially closed, then put a collapsed class on the toggle.

It also requires the :not selector, so it doesn't work on IE8.

HTML example:

<a class="btn btn-primary collapsed" data-toggle="collapse" href="#collapseExample">
  <!--You can put any valid html inside these!-->
  <span class="if-collapsed">Open</span>
  <span class="if-not-collapsed">Close</span>
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

Less version:

[data-toggle="collapse"] {
    &.collapsed .if-not-collapsed {
         display: none;
    }
    &:not(.collapsed) .if-collapsed {
         display: none;
    }
}

CSS version:

[data-toggle="collapse"].collapsed .if-not-collapsed {
  display: none;
}
[data-toggle="collapse"]:not(.collapsed) .if-collapsed {
  display: none;
}

Reason of Fail

You are using material library which is part of AndroidX. If you are not aware of AndroidX, please go through this answer.

One app should use either AndroidX or old Android Support libraries. That's why you faced this issue.

For example -

In your gradle, you are using

• com.android.support:appcompat-v7 (Part of old --Android Support Library--)
• com.google.android.material:material (Part of AndroidX) (AndroidX build artifact of com.android.support:design)

Solution

So the solution is to use either AndroidX or old Support Library. I recommend to use AndroidX, because Android will not update support libraries after version 28.0.0. See release notes of Support Library.

Just migrate to AndroidX.Here is my detailed answer to migrate to AndroidX. I am putting here the needful steps from that answer.

Before you migrate, it is strongly recommended to backup your project.

Existing project

• Android Studio > Refactor Menu > Migrate to AndroidX...
• It will analysis and will open Refractor window in bottom. Accept changes to be done.

New project

Put these flags in your gradle.properties

android.enableJetifier=true
android.useAndroidX=true

Check @Library mappings for equal AndroidX package.

Check @Official page of Migrate to AndroidX

What is Jetifier?

The short answer is for creating an attribute in c# you only need to inherit it from Attribute class, Just this :)

But here I'm going to explain attributes in detail:

basically attributes are classes that we can use them for applying our logic to assemblies, classes, methods, properties, fields, ...

In .Net, Microsoft has provided some predefined Attributes like Obsolete or Validation Attributes like ( [Required], [StringLength(100)], [Range(0, 999.99)]), also we have kind of attributes like ActionFilters in asp.net that can be very useful for applying our desired logic to our codes (read this article about action filters if you are passionate to learn it)

one another point, you can apply a kind of configuration on your attribute via AttibuteUsage.

  [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]

When you decorate an attribute class with AttributeUsage you can tell to c# compiler where I'm going to use this attribute: I'm going to use this on classes, on assemblies on properties or on ... and my attribute is allowed to use several times on defined targets(classes, assemblies, properties,...) or not?!

After this definition about attributes I'm going to show you an example: Imagine we want to define a new lesson in university and we want to allow just admins and masters in our university to define a new Lesson, Ok?

namespace ConsoleApp1
{
    /// <summary>
    /// All Roles in our scenario
    /// </summary>
    public enum UniversityRoles
    {
        Admin,
        Master,
        Employee,
        Student
    }

    /// <summary>
    /// This attribute will check the Max Length of Properties/fields
    /// </summary>
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]
    public class ValidRoleForAccess : Attribute
    {
        public ValidRoleForAccess(UniversityRoles role)
        {
            Role = role;
        }
        public UniversityRoles Role { get; private set; }

    }


    /// <summary>
    /// we suppose that just admins and masters can define new Lesson
    /// </summary>
    [ValidRoleForAccess(UniversityRoles.Admin)]
    [ValidRoleForAccess(UniversityRoles.Master)]
    public class Lesson
    {
        public Lesson(int id, string name, DateTime startTime, User owner)
        {
            var lessType = typeof(Lesson);
            var validRolesForAccesses = lessType.GetCustomAttributes<ValidRoleForAccess>();

            if (validRolesForAccesses.All(x => x.Role.ToString() != owner.GetType().Name))
            {
                throw new Exception("You are not Allowed to define a new lesson");
            }

            Name = name;

In the real world of programming maybe we don't use this approach for using attributes and I said this because of its educational point in using attributes

Iterate over an objects attributes in python:

class C:
    a = 5
    b = [1,2,3]
    def foobar():
        b = "hi"    

for attr, value in C.__dict__.iteritems():
    print "Attribute: " + str(attr or "")
    print "Value: " + str(value or "")

Prints:

python test.py
Attribute: a
Value: 5
Attribute: foobar
Value: <function foobar at 0x7fe74f8bfc08>
Attribute: __module__
Value: __main__
Attribute: b
Value: [1, 2, 3]
Attribute: __doc__
Value:

For those using Laravel, this https://github.com/sitepoint-editors/google-laravel-2FA is a nice way to solve this problem.

You also need to replace your indexes:

class RenameOldTableToNewTable< ActiveRecord:Migration
  def self.up
    remove_index :old_table_name, :column_name
    rename_table :old_table_name, :new_table_name
    add_index :new_table_name, :column_name
  end 

  def self.down
    remove_index :new_table_name, :column_name
    rename_table :new_table_name, :old_table_name
    add_index :old_table_name, :column_name
  end
end

And rename your files etc, manually as other answers here describe.

See: http://api.rubyonrails.org/classes/ActiveRecord/Migration.html

Make sure you can rollback and roll forward after you write this migration. It can get tricky if you get something wrong and get stuck with a migration that tries to effect something that no longer exists. Best trash the whole database and start again if you can't roll back. So be aware you might need to back something up.

Also: check schema_db for any relevant column names in other tables defined by a has_ or belongs_to or something. You'll probably need to edit those too.

And finally, doing this without a regression test suite would be nuts.

If you use recursion you can return object properties of any depth-

function lookdeep(object){
    var collection= [], index= 0, next, item;
    for(item in object){
        if(object.hasOwnProperty(item)){
            next= object[item];
            if(typeof next== 'object' && next!= null){
                collection[index++]= item +
                ':{ '+ lookdeep(next).join(', ')+'}';
            }
            else collection[index++]= [item+':'+String(next)];
        }
    }
    return collection;
}

//example

var O={
    a:1, b:2, c:{
        c1:3, c2:4, c3:{
            t:true, f:false
        }
    },
    d:11
};
var lookdeepSample= 'O={'+ lookdeep(O).join(',\n')+'}';


/*  returned value: (String)
O={
    a:1, 
    b:2, 
    c:{
        c1:3, c2:4, c3:{
            t:true, f:false
        }
    },
    d:11
}

*/

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

iTroid23 solution worked for me. I missed the Swift solution. So maybe this is helpful:

1) In my plist I had to add this:

<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>

2) I didn't need to call "setNeedsStatusBarAppearanceUpdate".

3) In swift I had to add this to my UIViewController:

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return UIStatusBarStyle.LightContent
}

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

From your example it seems reasonable to assume that the siteIP column is determined by the siteName column (that is, each site has only one siteIP). If this is indeed the case, then there is a simple solution using group by:

select
  sites.siteName,
  sites.siteIP,
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName,
  sites.siteIP
order by
  sites.siteName;

However, if my assumption is not correct (that is, it is possible for a site to have multiple siteIP), then it is not clear from you question which siteIP you want the query to return in the second column. If just any siteIP, then the following query will do:

select
  sites.siteName,
  min(sites.siteIP),
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName
order by
  sites.siteName;

An optimization trick that makes your code easier to maintain and less susceptible to a concurrency bug.

It requires more bytecodes to reference a class-scope variable than a method-scope variable. The addition of a method call prior to the critical loop adds little overhead (and the call might be inlined by the compiler anyway).

Another advantage to this technique (always using accessors) is that it eliminates a potential bug in the Slow class. If a second thread were to continually reset the value of i to 0 (by calling slow.setI( 0 ), for example), the Slow class could never end its loop. Calling the accessor and using a local variable eliminates that possibility.

Also, you can use bool method(s)

Query :

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where isValid(Field<string>("UserName"))// && otherMethod() && otherMethod2()                           
            select r;   

        DataTable newDT = query.CopyToDataTable();

Method:

bool isValid(string userName)
{
    if(userName == "XXXX" || userName == "YYYY")
        return false;
    else return true;
}

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

In case anyone else ends up here using Jupyter Notebooks, you just need

%matplotlib inline

Purpose of "%matplotlib inline"

You might need to run it via cmd, eg:

system("cmd /c C:[path to file]");

Please make sure your python or python3 can see xlrd installation. I had a situation where python3.5 and python3.7 were installed in two different locations. While xlrd was installed with python3.5, I was using python3 (from python3.7 dir) to run my script and got the same error reported above. When I used the correct python (viz. python3.5 dir) to run my script, I was able to read the excel spread sheet without a problem.

I just use this solution in Kotlin:

 var date : String = DateFormat.format("EEEE dd-MMM-yyyy HH:mm a" , Date()) as String

To be honest, as other posters have mentioned, Wikipedia has a very good article on this so have a look there. This type of error is very common and often called other things such as Access Violation or General Protection Fault.

They are no different in C, C++ or any other language that allows pointers. These kinds of errors are usually caused by pointers that are

1. Used before being properly initialised
2. Used after the memory they point to has been realloced or deleted.
3. Used in an indexed array where the index is outside of the array bounds. This is generally only when you're doing pointer math on traditional arrays or c-strings, not STL / Boost based collections (in C++.)

(Update: overlooked a fault in the matter, I have corrected)

(Update2: I wrote from memory the code screwed up, repaired it)

If its just about detecting whether or not you're dealing with an Object, I could think of

Object.getPrototypeOf( obj ) === Object.prototype

However, this would probably fail for non-object primitive values. Actually there is nothing wrong with invoking .toString() to retreive the [[cclass]] property. You can even create a nice syntax like

var type = Function.prototype.call.bind( Object.prototype.toString );

and then use it like

if( type( obj ) === '[object Object]' ) { }

It might not be the fastest operation but I don't think the performance leak there is too big.

For Sql Server 2017 and later you can use the new STRING_AGG function

https://docs.microsoft.com/en-us/sql/t-sql/functions/string-agg-transact-sql

The following example replaces null values with 'N/A' and returns the names separated by commas in a single result cell.

SELECT STRING_AGG ( ISNULL(FirstName,'N/A'), ',') AS csv 
FROM Person.Person;

Here is the result set.

John,N/A,Mike,Peter,N/A,N/A,Alice,Bob

Perhaps a more common use case is to group together and then aggregate, just like you would with SUM, COUNT or AVG.

SELECT a.articleId, title, STRING_AGG (tag, ',') AS tags 
FROM dbo.Article AS a       
LEFT JOIN dbo.ArticleTag AS t 
    ON a.ArticleId = t.ArticleId 
GROUP BY a.articleId, title;

Just a recommendation:

I'd recommend using the DOM table implementation, it's very straight forward and easy to use, you really don't need jQuery for this task.

var table = document.getElementById('tblOne');

var rowLength = table.rows.length;

for(var i=0; i<rowLength; i+=1){
  var row = table.rows[i];

  //your code goes here, looping over every row.
  //cells are accessed as easy

  var cellLength = row.cells.length;
  for(var y=0; y<cellLength; y+=1){
    var cell = row.cells[y];

    //do something with every cell here
  }
}

<div class="container" style="width: 100%;">
    <div class="sidebar" style="width: 200px; float: left;">
        Sidebar
    </div>
    <div class="content" style="margin-left: 202px;">
        content 
    </div>
</div>

This will be cross browser compatible. Without the margin-left you will run into issues with content running all the way to the left if you content is longer than your sidebar.

In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

Just do the following change

echo off
cls

echo Would you like to do a backup?

pause

copy "\\My_Servers_IP\Shared Drive\FolderName\*" C:\TEST_BACKUP_FOLDER

pause

This seems to be a recurring issue with 1GB and smaller server instances. Apart from trying to shutdown processes and tweak swap settings, you could install on a local machine and upload.

I got the same "No Android SDK Found" error message... plus no rendering for Design window, no little cellphone screen.

My SDK path was correct, pointing to where the (downloaded during setup) SDK lives.

During Setup of the SDK Mgr, I didn't download the latest "preview edition (version 20)"...(I thought it better to use the next most recent version (19)) Later I found, there was no dropdown choice in the AVD Manager to pick Version 19, only the default value of the preview, 20.

I thought "Maybe the rendering was based on a version that wasn't present yet." So, I downloaded all the "preview edition's (version 20)" SDK Platform (2) and system images (4)...

Once download/install completed, RESTARTED Android Studio and Viola! success... error message gone, rendering ok.

For very advanced JSON objects to HTML tables you can try My jQuery Solution that is based on this closed thread.

// Builds the HTML Table out of myList json data from Ivy restful service.
 function buildHtmlTable() {
      addTable(myList, $("#excelDataTable"));

i find best solution in https://dzone.com/articles/get-last-record-in-each-mysql-group

select * from `data` where `id` in (select max(`id`) from `data` group by `name_id`)

To compare two files in Eclipse, first select them in the Project Explorer / Package Explorer / Navigator with control-click. Now right-click on one of the files, and the following context menu will appear. Select Compare With / Each Other.

As said, the objectForKey: datatype is :(id)aKey whereas the valueForKey: datatype is :(NSString *)key.

For example:

 NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[NSArray arrayWithObject:@"123"],[NSNumber numberWithInteger:5], nil];

 NSLog(@"objectForKey : --- %@",[dict objectForKey:[NSNumber numberWithInteger:5]]);  
    //This will work fine and prints (    123    )  

 NSLog(@"valueForKey  : --- %@",[dict valueForKey:[NSNumber numberWithInteger:5]]); 
    //it gives warning "Incompatible pointer types sending 'NSNumber *' to parameter of type 'NSString *'"   ---- This will crash on runtime. 

So, valueForKey: will take only a string value and is a KVC method, whereas objectForKey: will take any type of object.

The value in objectForKey will be accessed by the same kind of object.

Depending on your use of Google Analytics data, if you want basic information (such as visits, UI interactions) you might be able to not include analytics.js at all, yet still collect data in GA.

One option may be to instead use the measurement protocol in a cached script. Google Analytics: Measurement Protocol Overview

When you set the transport method explicitly to image, you can see how GA constructs its own image beacons.

ga('set', 'transport', 'image');

https://www.google-analytics.com/r/collect
  ?v={protocol-version}
  &tid={tracking-id}
  &cid={client-id}
  &t={hit-type}
  &dl={location}

You could create your own GET or POST requests with the required payload.

However, if you require a greater level of detail it probably won't be worth your effort.

HTML:

<div class="CalendarBlock">
    <input type="hidden">
</div>

CODE:

$CalendarBlock=$('.CalendarBlock');
$CalendarBlock.click(function(){
    var $datepicker=$(this).find('input');
    datepicker.datepicker({dateFormat: 'mm/dd/yy'});
    $datepicker.focus(); });

You've got the syntax right:

WITH AuthorRating(AuthorName, AuthorRating) AS
   SELECT aname         AS AuthorName,
          AVG(quantity) AS AuthorRating
   FROM Book
   GROUP By Book.aname

However, as others have mentioned, MySQL does not support this command. WITH was added in SQL:1999; the newest version of the SQL standard is SQL:2008. You can find some more information about databases that support SQL:1999's various features on Wikipedia.

MySQL has traditionally lagged a bit in support for the SQL standard, whereas commercial databases like Oracle, SQL Server (recently), and DB2 have followed them a bit more closely. PostgreSQL is typically pretty standards compliant as well.

You may want to look at MySQL's roadmap; I'm not completely sure when this feature might be supported, but it's great for creating readable roll-up queries.

The equals sign (=) is used as padding in certain forms of base64 encoding. The Wikipedia article on base64 has all the details.

This is all you need to do:

var myVariable;

$.ajax({
    'async': false,
    'type': "POST",
    'global': false,
    'dataType': 'html',
    'url': "ajax.php?first",
    'data': { 'request': "", 'target': 'arrange_url', 'method': 'method_target' },
    'success': function (data) {
        myVariable = data;
    }
});

NOTE: Use of "async" has been depreciated. See https://xhr.spec.whatwg.org/.

Working with dates in javascript is always a bit of a hassle. I always end up using a library. Moment.js and XDate are both great:

http://momentjs.com/

http://arshaw.com/xdate/

Fiddle:

http://jsfiddle.net/39fWa/

var $output = $('#output'),
    tomorrow = moment().add('days', 1);

$('<pre />').appendTo($output).text(tomorrow);

tomorrow = new XDate().addDays(-1);

$('<pre />').appendTo($output).text(tomorrow);

Go to design for that table. Now, on the right, set the ID column as the column in question. It will now auto populate without specification.

It doesn't - at least during the compilation phase.

The translation of a c++ program from source code to machine code is performed in three phases:

1. Preprocessing - The Preprocessor parses all source code for lines beginning with # and executes the directives. In your case, the contents of your file class.h is inserted in place of the line #include "class.h. Since you might be includein your header file in several places, the #ifndef clauses avoid duplicate declaration-errors, since the preprocessor directive is undefined only the first time the header file is included.
2. Compilation - The Compiler does now translate all preprocessed source code files to binary object files.
3. Linking - The Linker links (hence the name) together the object files. A reference to your class or one of its methods (which should be declared in class.h and defined in class.cpp) is resolved to the respective offset in one of the object files. I write 'one of your object files' since your class does not need to be defined in a file named class.cpp, it might be in a library which is linked to your project.

In summary, the declarations can be shared through a header file, while the mapping of declarations to definitions is done by the linker.

It's 2015. I had to go to find a blog post that would explain how to do it for the latest version of iOS and XCode with Swift so that it would work with multiple lines.

1. set “Autoshrink” to “Minimum font size.”
2. set the font to the largest desirable font size (I chose 20)
3. Change “Line Breaks” from “Word Wrap” to “Truncate Tail.”

You need to grant access to root from localhost. Check this ubuntu help

In my case,I use the below solution

Front-end or Angular

post(
    this.serverUrl, dataObjToPost,
    {
      headers: new HttpHeaders({
           'Content-Type':  'application/json',
         })
    }
)

back-end (I use php)

header("Access-Control-Allow-Origin: http://localhost:4200");
header('Access-Control-Allow-Methods: GET, POST, OPTIONS');
header("Access-Control-Allow-Headers: Content-Type, Authorization");

$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
print_r($request);

Since iOS 8 came out, this problem does not exist any more. The scroll event is now fired smoothly in iOS Safari as well.

So, if you register the scroll event handler and check window.pageYOffset inside that event handler, everything works just fine.

To pass the value you must included the hidden value value="hiddenValue" in the <input> statement like so:

<input type="hidden" id="thisField" name="inputName" value="hiddenValue">

Then you recuperate the hidden form value in the same way that you recuperate the value of visible input fields, by accessing the parameter of the request object. Here is an example:

This code goes on the page where you want to hide the value.

<form action="anotherPage.jsp" method="GET">
    <input type="hidden" id="thisField" name="inputName" value="hiddenValue">
<input type="submit">   
</form>

Then on the 'anotherPage.jsp' page you recuperate the value by calling the getParameter(String name) method of the implicit request object, as so:

<% String hidden = request.getParameter("inputName"); %>
The Hidden Value is <%=hidden %>

The output of the above script will be:

The Hidden Value is hiddenValue 

You can change the array type without converting like this:

a.dtype = numpy.float32

but first you have to change all the integers to something that will be interpreted as the corresponding float. A very slow way to do this would be to use python's struct module like this:

def toi(i):
    return struct.unpack('i',struct.pack('f',float(i)))[0]

...applied to each member of your array.

But perhaps a faster way would be to utilize numpy's ctypeslib tools (which I am unfamiliar with)

- edit -

Since ctypeslib doesnt seem to work, then I would proceed with the conversion with the typical numpy.astype method, but proceed in block sizes that are within your memory limits:

a[0:10000] = a[0:10000].astype('float32').view('int32')

...then change the dtype when done.

Here is a function that accomplishes the task for any compatible dtypes (only works for dtypes with same-sized items) and handles arbitrarily-shaped arrays with user-control over block size:

import numpy

def astype_inplace(a, dtype, blocksize=10000):
    oldtype = a.dtype
    newtype = numpy.dtype(dtype)
    assert oldtype.itemsize is newtype.itemsize
    for idx in xrange(0, a.size, blocksize):
        a.flat[idx:idx + blocksize] = \
            a.flat[idx:idx + blocksize].astype(newtype).view(oldtype)
    a.dtype = newtype

a = numpy.random.randint(100,size=100).reshape((10,10))
print a
astype_inplace(a, 'float32')
print a

Here's some simple code to add a time out to your recv function using poll in C:

struct pollfd fd;
int ret;

fd.fd = mySocket; // your socket handler 
fd.events = POLLIN;
ret = poll(&fd, 1, 1000); // 1 second for timeout
switch (ret) {
    case -1:
        // Error
        break;
    case 0:
        // Timeout 
        break;
    default:
        recv(mySocket,buf,sizeof(buf), 0); // get your data
        break;
}

__all__ is very good - it helps guide import statements without automatically importing modules http://docs.python.org/tutorial/modules.html#importing-from-a-package

using __all__ and import * is redundant, only __all__ is needed

I think one of the most powerful reasons to use import * in an __init__.py to import packages is to be able to refactor a script that has grown into multiple scripts without breaking an existing application. But if you're designing a package from the start. I think it's best to leave __init__.py files empty.

for example:

foo.py - contains classes related to foo such as fooFactory, tallFoo, shortFoo

then the app grows and now it's a whole folder

foo/
    __init__.py
    foofactories.py
    tallFoos.py
    shortfoos.py
    mediumfoos.py
    santaslittlehelperfoo.py
    superawsomefoo.py
    anotherfoo.py

then the init script can say

__all__ = ['foofactories', 'tallFoos', 'shortfoos', 'medumfoos',
           'santaslittlehelperfoo', 'superawsomefoo', 'anotherfoo']
# deprecated to keep older scripts who import this from breaking
from foo.foofactories import fooFactory
from foo.tallfoos import tallFoo
from foo.shortfoos import shortFoo

so that a script written to do the following does not break during the change:

from foo import fooFactory, tallFoo, shortFoo

@echo off
set hour=%time:~0,2%
if "%hour:~0,1%"==" " set hour=0%time:~1,1%
set folder=%date:~6,4%%date:~3,2%%date:~0,2%%hour%%time:~3,2%

You can also define a custom theme that is derived from your base theme:

<android.support.design.widget.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:id="@+id/nav_view"
        app:headerLayout="@layout/nav_view_header"
        app:menu="@layout/nav_view_menu"
        app:theme="@style/MyTheme.NavMenu" />

and then in your styles.xml file:

  <style name="MyTheme.NavMenu" parent="MyTheme.Base">
    <item name="android:textColorPrimary">@color/yourcolor</item>
  </style>

you can also apply more attributes to the custom theme.

The man page explains that you can enter command line mode in a running session by typing Ctrl+A, :, then issuing the scrollback <num> command.

In case anyone else is using EPPlus. This implementation is pretty naive, but there are comments that draw attention to such. If you were to layer one more method GetWorkbookAsDataSet() on top it would do what the OP is asking for.

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

My issue turned out to be in the Publish settings in Visual Studio. My appsettings.json connection string was correct, but the Database connection strings in the publish settings, had integrated security = true.

When using merged columns, I got it centered by using PHPExcel_Style_Alignment::HORIZONTAL_CENTER_CONTINUOUS instead of PHPExcel_Style_Alignment::HORIZONTAL_CENTER

My database was larger than 500mb, I then used the following

C:\Windows>sqlcmd -S SERVERNAME -U USERNAME -P PASSWORD -d DATABASE -i C:\FILE.sql

It loaded everything including SP's

*NB: Run the cmd as Administrator

You can't avoid a server call here, JavaScript simply cannot (for security reasons) save a file to the user's file system. You'll have to submit your data to the server and have it send the .csv as a link or an attachment directly.

HTML5 has some ability to do this (though saving really isn't specified - just a use case, you can read the file if you want), but there's no cross-browser solution in place now.

I am using Laravel 5.4 and unfortunately although the accepted answer seems fine, for preflighted requests (like PUT and DELETE) which will be preceded by an OPTIONS request, specifying the middleware in the $routeMiddleware array (and using that in the routes definition file) will not work unless you define a route handler for OPTIONS as well. This is because without an OPTIONS route Laravel will internally respond to that method without the CORS headers.

So in short either define the middleware in the $middleware array which runs globally for all requests or if you're doing it in $middlewareGroups or $routeMiddleware then also define a route handler for OPTIONS. This can be done like this:

Route::match(['options', 'put'], '/route', function () {
    // This will work with the middleware shown in the accepted answer
})->middleware('cors');

I also wrote a middleware for the same purpose which looks similar but is larger in size as it tries to be more configurable and handles a bunch of conditions as well:

<?php

namespace App\Http\Middleware;

use Closure;

class Cors

    private static $allowedOriginsWhitelist = [
      'http://localhost:8000'

    public function handle($request, Closure $next)
    {
      if (! $this->isCorsRequest($request))
      {
        return $next($request);
      }

      static::$allowedOrigin = $this->resolveAllowedOrigin($request);

      static::$allowedHeaders = $this->resolveAllowedHeaders($request);

      $headers = [
        'Access-Control-Allow-Origin'       => static::$allowedOrigin,
        'Access-Control-Allow-Methods'      => static::$allowedMethods,
        'Access-Control-Allow-Headers'      => static::$allowedHeaders,
        'Access-Control-Allow-Credentials'  => static::$allowCredentials,
      ];

      // For preflighted requests
      if ($request->getMethod() === 'OPTIONS')
      {
        return response('', 200)->withHeaders($headers);
      }

      $response = $next($request)->withHeaders($headers);

      return $response;
    }

    /**
     * Incoming request is a CORS request if the Origin
     * header is set and Origin !== Host
     *
     * @param  \Illuminate\Http\Request  $request
     */
    private function isCorsRequest($request)
    {
      $requestHasOrigin = $request->headers->has('Origin');

      if ($requestHasOrigin)
      {
        $origin = $request->headers->get('Origin');

        $host = $request->getSchemeAndHttpHost();

     */
    private function resolveAllowedOrigin($request)
    {
      $allowedOrigin = static::$allowedOrigin;

      // If origin is in our $allowedOriginsWhitelist
      // then we send that in Access-Control-Allow-Origin

      $origin = $request->headers->get('Origin');

      if (in_array($origin, static::$allowedOriginsWhitelist))

    private function resolveAllowedHeaders($request)

}

If your HTML is like below you could do something like this:

<div ng-controller="ParentCtrl">
    <div ng-controller="ChildCtrl">
    </div>
</div>

Then you can access the parent scope as follows

function ParentCtrl($scope) {
    $scope.cities = ["NY", "Amsterdam", "Barcelona"];
}

function ChildCtrl($scope) {
    $scope.parentcities = $scope.$parent.cities;
}

If you want to access a parent controller from your view you have to do something like this:

<div ng-controller="xyzController as vm">
   {{$parent.property}}
</div>

See jsFiddle: http://jsfiddle.net/2r728/

Update

Actually since you defined cities in the parent controller your child controller will inherit all scope variables. So theoritically you don't have to call $parent. The above example can also be written as follows:

function ParentCtrl($scope) {
    $scope.cities = ["NY","Amsterdam","Barcelona"];
}

function ChildCtrl($scope) {
    $scope.parentCities = $scope.cities;
}

The AngularJS docs use this approach, here you can read more about the $scope.

Another update

I think this is a better answer to the original poster.

HTML

<div ng-app ng-controller="ParentCtrl as pc">
    <div ng-controller="ChildCtrl as cc">
        <pre>{{cc.parentCities | json}}</pre>
        <pre>{{pc.cities | json}}</pre>
    </div>
</div>

JS

function ParentCtrl() {
    var vm = this;
    vm.cities = ["NY", "Amsterdam", "Barcelona"];
}

function ChildCtrl() {
    var vm = this;
    ParentCtrl.apply(vm, arguments); // Inherit parent control

    vm.parentCities = vm.cities;
}

If you use the controller as method you can also access the parent scope as follows

function ChildCtrl($scope) {
    var vm = this;
    vm.parentCities = $scope.pc.cities; // note pc is a reference to the "ParentCtrl as pc"
}

As you can see there are many different ways in accessing $scopes.

Updated fiddle

function ParentCtrl() {_x000D_
    var vm = this;_x000D_
    vm.cities = ["NY", "Amsterdam", "Barcelona"];_x000D_
}_x000D_
    _x000D_
function ChildCtrl($scope) {_x000D_
    var vm = this;_x000D_
    ParentCtrl.apply(vm, arguments);_x000D_
    _x000D_
    vm.parentCitiesByScope = $scope.pc.cities;_x000D_
    vm.parentCities = vm.cities;_x000D_
}_x000D_
    

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.20/angular.min.js"></script>_x000D_

change this

audio.src='audio/ogg/' + document.getElementById(song1.ogg);

to

audio.src='audio/ogg/' + document.getElementById('song1');

special_func to avoid try-except repetition:

def special_func(test_case_dict):
    final_dict = {}
    exception_dict = {}

    def try_except_avoider(test_case_dict):

        try:
            for k,v in test_case_dict.items():
                final_dict[k]=eval(v) #If no exception evaluate the function and add it to final_dict

        except Exception as e:
            exception_dict[k]=e #extract exception
            test_case_dict.pop(k)
            try_except_avoider(test_case_dict) #recursive function to handle remaining functions

        finally:  #cleanup
            final_dict.update(exception_dict)
            return final_dict #combine exception dict and  final dict

    return try_except_avoider(test_case_dict) 

Run code:

def add(a,b):
    return (a+b)
def sub(a,b):
    return (a-b)
def mul(a,b):
    return (a*b)

case = {"AddFunc":"add(8,8)","SubFunc":"sub(p,5)","MulFunc":"mul(9,6)"}
solution = special_func(case)

Output looks like:

{'AddFunc': 16, 'MulFunc': 54, 'SubFunc': NameError("name 'p' is not defined")}

To convert to variables:

locals().update(solution)

Variables would look like:

AddFunc = 16, MulFunc = 54, SubFunc = NameError("name 'p' is not defined")

Use char for 16 bit unsigned integers.

In PyUnit there's a method which compares dictionaries beautifully. I tested it using the following two dictionaries, and it does exactly what you're looking for.

d1 = {1: "value1",
      2: [{"subKey1":"subValue1",
           "subKey2":"subValue2"}]}
d2 = {1: "value1",
      2: [{"subKey2":"subValue2",
           "subKey1": "subValue1"}]
      }


def assertDictEqual(self, d1, d2, msg=None):
        self.assertIsInstance(d1, dict, 'First argument is not a dictionary')
        self.assertIsInstance(d2, dict, 'Second argument is not a dictionary')

        if d1 != d2:
            standardMsg = '%s != %s' % (safe_repr(d1, True), safe_repr(d2, True))
            diff = ('\n' + '\n'.join(difflib.ndiff(
                           pprint.pformat(d1).splitlines(),
                           pprint.pformat(d2).splitlines())))
            standardMsg = self._truncateMessage(standardMsg, diff)
            self.fail(self._formatMessage(msg, standardMsg))

I'm not recommending importing unittest into your production code. My thought is the source in PyUnit could be re-tooled to run in production. It uses pprint which "pretty prints" the dictionaries. Seems pretty easy to adapt this code to be "production ready".

Use a FULL OUTER JOIN:

select 
   a.col_a,
   a.col_b,
   b.col_c
from
   (select col_a,col_bfrom tab1) a
join 
   (select col_a,col_cfrom tab2) b 
on a.col_a= b.col_a

For mac users,

It was working fine yesterday, now the hell broke. I was able to fix it.

My issue was with ANDROID_HOME

// This is wrong. No idea how it was working earlier.
ANDROID_HOME = Library/Android/sdk 

If you did the same, change it to:

ANDROID_HOME = /Users/rana.singh/Library/Android/sdk 

.bash_profile has

export ANDROID_HOME=/Users/rana.singh/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

First, make sure you are on the right branch.
Then (one time only):

git branch --track

After that this works again:

git pull

After trying many tutorials to configure my Ubuntu 16.04 LTS behind a authenticated proxy, it worked with these steps:

Edit /etc/wgetrc:

$ sudo nano /etc/wgetrc

Uncomment these lines:

#https_proxy = http://proxy.yoyodyne.com:18023/
#http_proxy = http://proxy.yoyodyne.com:18023/
#ftp_proxy = http://proxy.yoyodyne.com:18023/
#use_proxy = on

Change http://proxy.yoyodyne.com:18023/ to http://username:password@domain:port/

IMPORTANT: If it still doesn't work, check if your password has special characters, such as #, @, ... If this is the case, escape them (for example, replace passw@rd with passw%40rd).

My solution is to pull on the other working copy and then do:

git log --pretty="format:" --name-only -n1 | xargs git checkout HEAD^1

which says get all the file paths in the latest comment, and check them out from the parent of HEAD. Job done.

The accepted answer doesn't cut it because if a user de-selects a row the list is not updated accordingly.

Here is what I suggest instead:

Private Sub CommandButton2_Click()
    Dim lItem As Long

    For lItem = 0 To ListBox1.ListCount - 1
        If ListBox1.Selected(lItem) = True Then
            MsgBox(ListBox1.List(lItem))
        End If
    Next
End Sub

From the nodejs documentation you should do this - always remember a string without knowing the encoding is just a bunch of bytes:

var readable = getReadableStreamSomehow();
readable.setEncoding('utf8');
readable.on('data', function(chunk) {
  assert.equal(typeof chunk, 'string');
  console.log('got %d characters of string data', chunk.length);
})

Your HTML file is not going to interact with C# directly, but you can write some C# to behave as if it were the HTML file.

For example: there is a class called System.Net.WebClient with simple methods:

using System.Net;
using System.Collections.Specialized;

...
using(WebClient client = new WebClient()) {

    NameValueCollection vals = new NameValueCollection();
    vals.Add("test", "test string");
    client.UploadValues("http://www.someurl.com/page.php", vals);
}

For more documentation and features, refer to the MSDN page.

@Dinh Nhat, your setter method looks wrong because you put a primitive type there again and it should be:

public void setClient_os_id(Integer clientOsId) {
client_os_id = clientOsId;
}

Something like this should work: /([^/]*)$

What language are you using? End-of-string regex signifiers can vary in different languages.

Replace [ with nothing, then ] with nothing.

Old, but maybe useful for readers to have a full example of how use modal.

I do like following ( working example jsfiddle ) :

$('button.btn.btn-success').click(function(event)
{

event.preventDefault();

$.post('getpostcodescript.php', $('form').serialize(), function(data, status, xhr)
    {
        // do something here with response;
        console.info(data);
        console.info(status);
        console.info(xhr);
    })
    .done(function() {
        // do something here if done ;
        alert( "saved" );
    })
    .fail(function() {
        // do something here if there is an error ;
        alert( "error" );
    })
    .always(function() {
        // maybe the good state to close the modal
        alert( "finished" );
        // Set a timeout to hide the element again
        setTimeout(function(){
          $("#myModal").hide();
        }, 3000);
    });
});

To deal easier with modals, I recommend using eModal, which permit to go faster on base use of bootstrap 3 modals.

The click will affect a label if we have one attached to the input checkbox?

I think that is better to use the .change() function

<input type="checkbox" id="something" />

$("#something").change( function(){
  alert("state changed");
});

This also handles the keyboard activation.

    private void dgvApps_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        if(dgvApps.CurrentCell.GetType() == typeof(DataGridViewCheckBoxCell))
        {
            if (dgvApps.CurrentCell.IsInEditMode)
            {
                if (dgvApps.IsCurrentCellDirty)
                {
                    dgvApps.EndEdit();
                }
            }
        }
    }


    private void dgvApps_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
          // handle value changed.....
    }

The MaterialModule was deprecated in the beta3 version with the goal that developers should only import into their applications what they are going to use and thus improve the bundle size.

The developers have now 2 options:

• Create a custom MyMaterialModule which imports/exports the components that your application requires and can be imported by other (feature) modules in your application.
• Import directly the individual material modules that a module requires into it.

Take the following as example (extracted from material page)

First approach:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
  imports: [MdButtonModule, MdCheckboxModule],
  exports: [MdButtonModule, MdCheckboxModule],
})
export class MyOwnCustomMaterialModule { }

Then you can import this module into any of yours.

Second approach:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
  ...
  imports: [MdButtonModule, MdCheckboxModule],
  ...
})
export class PizzaPartyAppModule { }

Now you can use the respective material components in all the components declared in PizzaPartyAppModule

It is worth mentioning the following:

• With the latest version of material, you need to import BrowserAnimationsModule into your main module if you want the animations to work
• With the latest version developers now need to add @angular/cdk to their package.json (material dependency)
• Import the material modules always after BrowserModule, as stated by the docs:

Whichever approach you use, be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules.

This error happened to me when I was using Visual Studio Code. I think it must have been because I was trying to build a project while there was an executable running in the same bin\debug folder. I stopped the executable, closed the folder, reopened, rebuilt, and the error went away.

It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.

In other words, %count% is replaced with its value 1 before running the loop.

What you need is something like:

setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
  set /a count += 1
  echo !count!
)
endlocal

Delayed expansion using ! instead of % will give you the expected behaviour. See also here.

Also keep in mind that setlocal/endlocal actually limit scope of things changed inside so that they don't leak out. If you want to use count after the endlocal, you have to use a "trick" made possible by the very problem you're having:

endlocal && set count=%count%

Let's say count has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:

endlocal && set count=7

Then, when it's executed, the inner scope is closed off, returning count to it's original value. But, since the setting of count to seven happens in the outer scope, it's effectively leaking the information you need.

You can string together multiple sub-commands to leak as much information as you need:

endlocal && set count=%count% && set something_else=%something_else%

I had a similar problem, but in my case, I have content in my div that height-wise will exceed the boundaries of the parent div. When it does, I want it to auto-scroll. I was able to accomplish this by using

.vscrolling_container { height: 100%; overflow: auto; }

Well, I'm not sure to understand your question...

In C, Char[] and Char* are the same thing.

Edit : thanks for this interesting link.

You need to set the Identity seed to that value:

CREATE TABLE orders
(
 id int IDENTITY(9586,1)
)

To alter an existing table:

ALTER TABLE orders ALTER COLUMN Id INT IDENTITY (9586, 1);

More info on CREATE TABLE (Transact-SQL) IDENTITY (Property)

The problem is that date takes your request quite literally and tries to use a date of 31st September (being 31st October minus one month) and then because that doesn't exist it moves to the next day which does. The date documentation (from info date) has the following advice:

The fuzz in units can cause problems with relative items. For example, `2003-07-31 -1 month' might evaluate to 2003-07-01, because 2003-06-31 is an invalid date. To determine the previous month more reliably, you can ask for the month before the 15th of the current month. For example:

 $ date -R
 Thu, 31 Jul 2003 13:02:39 -0700
 $ date --date='-1 month' +'Last month was %B?'
 Last month was July?
 $ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!'
 Last month was June!

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

if you want to access table cell

WebElement thirdCell = driver.findElement(By.Xpath("//table/tbody/tr[2]/td[1]")); 

If you want to access nested table cell -

WebElement thirdCell = driver.findElement(By.Xpath("//table/tbody/tr[2]/td[2]"+//table/tbody/tr[1]/td[2]));

All these patterns, MVC, MVVM, MVP, and Presentation Model, can be applied to Android apps, but without a third-party framework, it is not easy to get well-organized structure and clean code.

MVVM is originated from PresentationModel. When we apply MVC, MVVM, and Presentation Model to an Android app, what we really want is to have a clear structured project and more importantly easier for unit tests.

At the moment, without an third-party framework, you usually have lots of code (like addXXListener(), findViewById(), etc.), which does not add any business value. What's more, you have to run Android unit tests instead of normal JUnit tests, which take ages to run and make unit tests somewhat impractical.

For these reasons, some years ago we started an open source project, RoboBinding - A data-binding Presentation Model framework for the Android platform. RoboBinding helps you write UI code that is easier to read, test, and maintain. RoboBinding removes the need of unnecessary code like addXXListener or so, and shifts UI logic to the Presentation Model, which is a POJO and can be tested via normal JUnit tests. RoboBinding itself comes with more than 300 JUnit tests to ensure its quality.

Push only single file

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture:

Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);

customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;

DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));

The database user also seems to be case-sensitive, so while I had a root'@'% user I didn't have a ROOT'@'% user. I changed the user to be uppercase via workbench and the problem was resolved!

You can fetch the list of tables and schemata by querying the SQLITE_MASTER table:

sqlite> .tab
job         snmptarget  t1          t2          t3        
sqlite> select name from sqlite_master where type = 'table';
job
t1
t2
snmptarget
t3

sqlite> .schema job
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
);
sqlite> select sql from sqlite_master where type = 'table' and name = 'job';
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
)

Just in case you would need to delete a variable, you could use SETENV from Vincent Fatica available at http://barnyard.syr.edu/~vefatica. Not exactly recent ('98) but still working on Windows 7 x64.

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

Follow this :

1. File > Preferences > setting
2. In search type -> git path
3. Now scroll down a little > you will see "Git:path" section.
4. Click "Edit in settings.json".
5. Now just paste this path there "C:\\Program Files\\Git\\mingw64\\libexec\\git-core\\git.exe"

Restart VSCode and open new terminal in VSCode and try "git version"

In case still problem exists :

1. Inside terminal click on terminal options (1:Poweshell)
2. Select default shell
3. Select bash

open new terminal and change terminal option to 2:Bash Again try "git version" - this should work :)

This is caused because you are running a adb other than the one included in the SDK. If on linux check where is the adb binary located

which adb
Expected Output : ANDROID_SDK/platform-tools/adb

If not pointing to ANDROID_SDK/platform-tools/adb then you are running some old version of adb installed on a different location on the machine.

Nothing wrong running adb other than the one provided with SDK but the downside is it is not updated automatically when the android SDK is updated and that's why you running into this out-dated version issue.

The easier fix and to avoid this issue in future rename the older (misleading) adb binary file to something else.

Follow the steps to resolve this issue.

$ which adb
*o/p /usr/bin/adb  -   (output will depend on your machine)*
$ cd /usr/bin/
$ ls -lt | grep adb
*o/p -rwxr-xr-x 1 root   root      160912 Mar 31  2016 adb*
$ sudo mv adb adb_bakup
$ ls -lt | grep adb
o/p -rwxr-xr-x 1 root   root      160912 Mar 31  2016 adb_bakup
$ export PATH="/path/to/android_sdk/platform-tools:$PATH"
$ which adb  
*o/p <your android sdk dir>/platform-tools/adb*   ---> You are all good now

The value you are setting in the timeout attribute is the one of the correct ways to set the session timeout value.

The timeout attribute specifies the number of minutes a session can be idle before it is abandoned. The default value for this attribute is 20.

By assigning a value of 1 to this attribute, you've set the session to be abandoned in 1 minute after its idle.

To test this, create a simple aspx page, and write this code in the Page_Load event,

Response.Write(Session.SessionID);

Open a browser and go to this page. A session id will be printed. Wait for a minute to pass, then hit refresh. The session id will change.

Now, if my guess is correct, you want to make your users log out as soon as the session times out. For doing this, you can rig up a login page which will verify the user credentials, and create a session variable like this -

Session["UserId"] = 1;

Now, you will have to perform a check on every page for this variable like this -

if(Session["UserId"] == null)
    Response.Redirect("login.aspx");

This is a bare-bones example of how this will work.

But, for making your production quality secure apps, use Roles & Membership classes provided by ASP.NET. They provide Forms-based authentication which is much more reliabletha the normal Session-based authentication you are trying to use.

This is the safest solution:

git stash

Now you can do whatever you want without fear of conflicts.

For instance:

git checkout origin/master

If you want to include the remote changes in the master branch you can do:

git reset --hard origin/master

This will make you branch "master" to point to "origin/master".

Although it's not possible in general to do what's been asked, it's still often useful to have a count of how many items were iterated over after having iterated over them. For that, you can use jaraco.itertools.Counter or similar. Here's an example using Python 3 and rwt to load the package.

$ rwt -q jaraco.itertools -- -q
>>> import jaraco.itertools
>>> items = jaraco.itertools.Counter(range(100))
>>> _ = list(counted)
>>> items.count
100
>>> import random
>>> def gen(n):
...     for i in range(n):
...         if random.randint(0, 1) == 0:
...             yield i
... 
>>> items = jaraco.itertools.Counter(gen(100))
>>> _ = list(counted)
>>> items.count
48

The proper way to do it is probably to break down the method by putting the try-catch block in a separate method, and use a return statement:

public void someMethod() {
    try {
        ...
        if (condition)
            return;
        ...
    } catch (SomeException e) {
        ...
    }
}

If the code involves lots of local variables, you may also consider using a break from a labeled block, as suggested by Stephen C:

label: try {
    ...
    if (condition)
        break label;
    ...
} catch (SomeException e) {
    ...
}

$(function(){
    $("#testselectset").selectBoxIt({
        theme: "default",
        defaultText: "Make a selection...",
        autoWidth: false
    });
});

CSS Code

.selectboxit-container .selectboxit, .selectboxit-container .selectboxit-options {
    width: 400px; /* Width of the dropdown button */
    border-radius:0;
    max-height:100px;
}

.selectboxit-options .selectboxit-option .selectboxit-option-anchor {
    white-space: normal;
    min-height: 30px;
    height: auto;
}

and you have to add some Jquery Library select Box Jquery CSS

You can add your own css property for button size as follows:

.btn {
    min-width: 250px;
}

Any changes you commit, like deleting all your project files, will still be in place after a pull. All a pull does is merge the latest changes from somewhere else into your own branch, and if your branch has deleted everything, then at best you'll get merge conflicts when upstream changes affect files you've deleted. So, in short, yes everything is up to date.

If you describe what outcome you'd like to have instead of "all files deleted", maybe someone can suggest an appropriate course of action.

Update:

GET THE MOST RECENT OF THE CODE ON MY SYSTEM

What you don't seem to understand is that you already have the most recent code, which is yours. If what you really want is to see the most recent of someone else's work that's on the master branch, just do:

git fetch upstream
git checkout upstream/master

Note that this won't leave you in a position to immediately (re)start your own work. If you need to know how to undo something you've done or otherwise revert changes you or someone else have made, then please provide details. Also, consider reading up on what version control is for, since you seem to misunderstand its basic purpose.

Use StringBuilder:

StringBuilder sb = new StringBuilder(str);
sb.setCharAt(i - 1, 'k');
str = sb.toString();

I would definitely split them. It would be easy to sort the numbers by area code and contry code. But even if you're not going to split, just insert the numbers into the DB in one certain format. e.g. 1-555-555-1212 Your client side will be thankfull for not making it reformat your numbers.

Use Arrays class in Java which will return you an ArrayList :

final List<String> characters = Arrays.asList("+","-");

You will need a bit more work if you need a List<Character>.

Group Join method is unnecessary to achieve joining of two data sets.

Inner Join:

var qry = Foos.SelectMany
            (
                foo => Bars.Where (bar => foo.Foo_id == bar.Foo_id),
                (foo, bar) => new
                    {
                    Foo = foo,
                    Bar = bar
                    }
            );

For Left Join just add DefaultIfEmpty()

var qry = Foos.SelectMany
            (
                foo => Bars.Where (bar => foo.Foo_id == bar.Foo_id).DefaultIfEmpty(),
                (foo, bar) => new
                    {
                    Foo = foo,
                    Bar = bar
                    }
            );

EF and LINQ to SQL correctly transform to SQL. For LINQ to Objects it is beter to join using GroupJoin as it internally uses Lookup. But if you are querying DB then skipping of GroupJoin is AFAIK as performant.

Personlay for me this way is more readable compared to GroupJoin().SelectMany()

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

It's possible if you are using PHP 5.3.0 or higher.

See Anonymous Functions in the manual.

In your case, you would define exampleMethod like this:

function exampleMethod($anonFunc) {
    //execute anonymous function
    $anonFunc();
}

Here's a response to your latest question about the difference between x86_64 and arm64:

• x86_64 architecture is required for running the 64bit simulator.

• arm64 architecture is required for running the 64bit device (iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini with Retina display).
