Just in case someone else was struggeling with the accepted answer:

There are different OnCheckedChangeListener-Interfaces. I added to first one to see if a CheckBox was changed.

import android.widget.CompoundButton.OnCheckedChangeListener;

vs

import android.widget.RadioGroup.OnCheckedChangeListener;

When adding the snippet from Ricky I had errors:

The method setOnCheckedChangeListener(RadioGroup.OnCheckedChangeListener) in the type RadioGroup is not applicable for the arguments (new CompoundButton.OnCheckedChangeListener(){})

Can be fixed with answer from Ali :

new RadioGroup.OnCheckedChangeListener()

you should check the radiobutton in the radiogroup like this:

radiogroup.check(IdOfYourButton)

Of course you first have to set an Id to your radiobuttons

EDIT: i forgot, radioButton.getId() works as well, thx Ramesh

EDIT2:

android:checkedButton="@+id/my_radiobtn"

works in radiogroup xml

Late to the party, but here is a simplification of @Tarek360's Kotlin answer that caters for RadioGroups that might contain non-RadioButtons:

    val RadioGroup.checkedIndex: Int
        get() = children
            .filter { it is RadioButton }
            .indexOfFirst { it.id == checkedRadioButtonId }

If you're RadioFroup definitely only has RadioButtons then this can be a simple as:

    private val RadioGroup.checkedIndex = 
        children.indexOfFirst { it.id == checkedRadioButtonId }

Then you don't have the overhead of findViewById.

Ok here's how I fixed this

My model is a list of categories. Each category contains a list of its subcategories.
with this in mind, every time in the foreach loop, each RadioButton will have its category's ID (which is unique) as its name attribue.
And I also used Html.RadioButton instead of Html.RadioButtonFor.

Here's the final 'working' pseudo-code:

@foreach (var cat in Model.Categories)
{
  //A piece of code & html here
  @foreach (var item in cat.SubCategories)
  {
     @Html.RadioButton(item.CategoryID.ToString(), item.ID)
  }    
}

The result is:

<input name="127" type="radio" value="110">

Please note that I HAVE NOT put all these radio button groups inside a form. And I don't know if this solution will still work properly in a form.

Thanks to all of the people who helped me solve this ;)

I prefer to use

RadioButton b = (RadioButton) findViewById(R.id.option1);
b.performClick();

instead of using the accepted answer.

RadioButton b = (RadioButton) findViewById(R.id.option1);
b.setChecked(true);

The reason is setChecked(true) only changes the checked state of radio button. It does not trigger the onClick() method added to your radio button. Sometimes this might waste your time to debug why the action related to onClick() not working.

This is very simple you need to keep different names of every radio input group.

      <input type="radio" name="price">Thousand<br>_x000D_
      <input type="radio" name="price">Lakh<br>_x000D_
      <input type="radio" name="price">Crore_x000D_
      _x000D_
      </br><hr>_x000D_
_x000D_
      <input type="radio" name="gender">Male<br>_x000D_
      <input type="radio" name="gender">Female<br>_x000D_
      <input type="radio" name="gender">Other

Use ng-value instead of value.

ng-value="true"

Version with ng-checked is worse because of the code duplication.

All you need to do is use getCheckedRadioButtonId() and isChecked() method,

if(gender.getCheckedRadioButtonId()==-1)
{
    Toast.makeText(getApplicationContext(), "Please select Gender", Toast.LENGTH_SHORT).show();
}
else
{
    // get selected radio button from radioGroup
    int selectedId = gender.getCheckedRadioButtonId();
    // find the radiobutton by returned id
    selectedRadioButton = (RadioButton)findViewById(selectedId);
    Toast.makeText(getApplicationContext(), selectedRadioButton.getText().toString()+" is selected", Toast.LENGTH_SHORT).show();
}

In php:

• stripos() function is used to find the position of the first occurrence of a case-insensitive substring in a string.

• strripos() function is used to find the position of the last occurrence of a case-insensitive substring in a string.

Sample code:

$string = 'This is a string';
$substring ='i';
$firstIndex = stripos($string, $substring);
$lastIndex = strripos($string, $substring);

echo 'Fist index = ' . $firstIndex . ' ' . 'Last index = '. $lastIndex;

Output: Fist index = 2 Last index = 13

Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026

Now you should use:

http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.

For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.

So in the end you would have an URL like this:

http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg

EXCLUDE="foo bar blah jah"                                                                             
DEST=$1

for i in *
do
    for x in $EXCLUDE
    do  
        if [ $x != $i ]; then
            cp -a $i $DEST
        fi  
    done
done

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

Close the current interpreter using exit() command and reopen typing python to start your work. And do not name a list as list literally. Then you will be fine.

SELECT 
pg_terminate_backend(pid) 
FROM 
pg_stat_activity 
WHERE
pid <> pg_backend_pid()
-- no need to kill connections to other databases
AND datname = current_database();
-- use current_database by opening right query tool

It is called the conditional operator.

You can replace it with:

int qempty(){ 
    if (f == r) return 1;
    else return 0;
}

This happens if you forgot to change your build settings to Simulator. Unless you want to build to a device, in which case you should see the other answers.

In Eclipse Kepler,

1. go to Help, select ‘Install New Software’
2. Choose “Kepler- http://download.eclipse.org/releases/kepler” site or add it in if it’s missing.
3. Expand “Web, XML, and Java EE Development” section Check JST Server Adapters and JST Server Adapters Extensions and install it

After Eclipse restart, go to Window / Preferences / Server / Runtime Environments

You can give a try to Apache Commons Collections.

There is a class CollectionUtils that allows you to select or filter items by custom Predicate.

Your code would be like this:

Predicate condition = new Predicate() {
   boolean evaluate(Object sample) {
        return ((Sample)sample).value3.equals("three");
   }
};
List result = CollectionUtils.select( list, condition );

Update:

In java8, using Lambdas and StreamAPI this should be:

List<Sample> result = list.stream()
     .filter(item -> item.value3.equals("three"))
     .collect(Collectors.toList());

much nicer!

BlueBell's answer is right, you can do it by:

npm uninstall cordova ionic

Are you planning to re-install it? If you feel something's wrong which is causing problems then you should update npm and clean npm's cache.

npm cache clean -f
npm install npm -g

If problems still persist, I'd suggest re-install of NPM and Node.

npm uninstall node
apt-get purge npm
apt-get install npm
npm install node -g

Let me know if you face issues in the process.

This might be what you are looking for:

<?php

$text = 'This is a Simple text.';

// this echoes "is is a Simple text." because 'i' is matched first
echo strpbrk($text, 'mi');

// this echoes "Simple text." because chars are case sensitive
echo strpbrk($text, 'S');
?>

Is it?

Or maybe this:

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Or even this

<?php
$email  = '[email protected]';
$domain = strstr($email, '@');
echo $domain; // prints @example.com

$user = strstr($email, '@', true); // As of PHP 5.3.0
echo $user; // prints name
?>

You can read all about them in the documentation here:

http://php.net/manual/en/book.strings.php

you don't need this code

<?php
function display()
{
echo "hello".$_POST["studentname"];
}
?>

Instead, you can check whether the form is submitted by checking the post variables using isset.

here goes the code

if(isset($_POST)){
echo "hello ".$_POST['studentname'];
}

click here for the php manual for isset

As Andrew said, your text should be doing just that.

There is one instance that I can think of that will behave in the manner you suggest, and that is if you have the whitespace property set.

See if you don't have the following in your CSS somewhere:

white-space: nowrap

That will cause text to continue on the same line until interrupted by a line break.

OK, my apologies, not sure if edited or added the mark-up afterwards (didn't see it at first).

The overflow-x property is what's causing the scroll bar to appear. Remove that and the div will adjust to as high as it needs to be to contain all your text.

If a function does not return anything, e.g.:

def test():
    pass

it has an implicit return value of None.

Thus, as your pick* methods do not return anything, e.g.:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")

the lines that call them, e.g.:

word = pickEasy()

set word to None, so wordInput in getInput is None. This means that:

if guess in wordInput:

is the equivalent of:

if guess in None:

and None is an instance of NoneType which does not provide iterator/iteration functionality, so you get that type error.

The fix is to add the return type:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

Trigger DataTable search function after initializing DataTable with a blank string in it. It will automatically adjust misalignment of thead with tbody.

$( document ).ready(function()
{

    $('#monitor_data_voyage').DataTable( {
        scrollY:150,
        bSort:false,
        bPaginate:false,
        sScrollX: "100%",
        scrollX: true,
    } );

    setTimeout( function(){
       $('#monitor_data_voyage').DataTable().search( '' ).draw();
    }, 10 );

});

Factory pattern: The factory produces IProduct-implementations

Abstract Factory Pattern: A factory-factory produces IFactories, which in turn produces IProducts :)

[Update according to the comments]
What I wrote earlier is not correct according to Wikipedia at least. An abstract factory is simply a factory interface. With it, you can switch your factories at runtime, to allow different factories in different contexts. Examples could be different factories for different OS'es, SQL providers, middleware-drivers etc..

To get the fields info too, you can use the following:

SELECT TABLE_SCHEMA, TABLE_NAME, 
       COLUMN_NAME, substring(DATA_TYPE, 1,1) AS DATA_TYPE
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA NOT IN("information_schema", "mysql", "performance_schema") 
ORDER BY TABLE_SCHEMA, TABLE_NAME, ORDINAL_POSITION

Lexical scoping: Variables declared outside of a function are global variables and are visible everywhere in a JavaScript program. Variables declared inside a function have function scope and are visible only to code that appears inside that function.

I noticed there was not an actual full code answer, so as i come across this, i have created a function, that does change the font, which can be easily modified. I have tested this in

- XP SP3 and Win 10 Pro 64

private void SetFont(Form f, string name, int size, FontStyle style)
{
    Font replacementFont = new Font(name, size, style);
    f.Font = replacementFont;
}

Hint: replace Form to either Label, RichTextBox, TextBox, or any other relative control that uses fonts to change the font on them. By using the above function thus making it completely dynamic.

    /// To call the function do this.
    /// e.g in the form load event etc.

public Form1()
{
      InitializeComponent();
      SetFont(this, "Arial", 8, FontStyle.Bold);  
      // This sets the whole form and 
      // everything below it.
      // Shaun Cassidy.
}

You can also, if you want a full libary so you dont have to code all the back end bits, you can download my dll from Github.

Github DLL

/// and then import the namespace
using Droitech.TextFont;

/// Then call it using:
TextFontClass fClass = new TextFontClass();
fClass.SetFont(this, "Arial", 8, FontStyle.Bold);

Simple.

In Django 3, you want to use url template tag:

{% url 'name-of-your-user-profile-url' possible_context_variable_parameter %}

For an example, see the documentation

Exceptions are a good way to handle unexpected events in your application flow. RuntimeException are unchecked by the Compiler but you may prefer to use Exceptions that extend Exception Class to control the behaviour of your api clients as they are required to catch errors for them to compile. Also forms good documentation.

If want to achieve clean interface use inheritance to subclass the different types of exception your application has and then expose the parent exception.

Check out http://mywiki.wooledge.org/DotFiles for an excellent resource on the topic aside from man bash.

Summary:

• You only log in once, and that's when ~/.bash_profile or ~/.profile is read and executed. Since everything you run from your login shell inherits the login shell's environment, you should put all your environment variables in there. Like LESS, PATH, MANPATH, LC_*, ... For an example, see: My .profile
• Once you log in, you can run several more shells. Imagine logging in, running X, and in X starting a few terminals with bash shells. That means your login shell started X, which inherited your login shell's environment variables, which started your terminals, which started your non-login bash shells. Your environment variables were passed along in the whole chain, so your non-login shells don't need to load them anymore. Non-login shells only execute ~/.bashrc, not /.profile or ~/.bash_profile, for this exact reason, so in there define everything that only applies to bash. That's functions, aliases, bash-only variables like HISTSIZE (this is not an environment variable, don't export it!), shell options with set and shopt, etc. For an example, see: My .bashrc
• Now, as part of UNIX peculiarity, a login-shell does NOT execute ~/.bashrc but only ~/.profile or ~/.bash_profile, so you should source that one manually from the latter. You'll see me do that in my ~/.profile too: source ~/.bashrc.

If you do have to do it this way, here's a few ways of doing it:

Disabling the button with ng-disabled

By far the easiest solution.

<input ng-disabled="!profileForm.$valid" ng-click="updateMyProfile()" ... >

Hiding the button (and showing something else) with ng-if

Might be OK if you're showing/hiding some complex markup.

<div ng-if="profileForm.$valid">
    <input ng-click="updateMyProfile()" ... >
</div>
<div ng-if="!profileForm.$valid">
    Sorry! We need all form fields properly filled out to continue.
</div>

(remember, there's no ng-else ...)

A mix of both

Communicating to the user where the button is (he won't look for it any longer), but explain why it can't be clicked.

<input ng-disabled="!profileForm.$valid" ng-click="updateMyProfile()" ... >
<div ng-if="!profileForm.$valid">
    Sorry! We need all form fields properly filled out to continue.
</div>

Most of these answers explain what %n does (which is to print nothing and to write the number of characters printed thus far to an int variable), but so far no one has really given an example of what use it has. Here is one:

int n;
printf("%s: %nFoo\n", "hello", &n);
printf("%*sBar\n", n, "");

will print:

hello: Foo
       Bar

with Foo and Bar aligned. (It's trivial to do that without using %n for this particular example, and in general one always could break up that first printf call:

int n = printf("%s: ", "hello");
printf("Foo\n");
printf("%*sBar\n", n, "");

Whether the slightly added convenience is worth using something esoteric like %n (and possibly introducing errors) is open to debate.)

If just wanted to show math in the browser for yourself, you could try the Chrome extension GitHub with MathJax. It's quite convenient.

If you really want to use regex, then

>>> df.replace('(^\s+|\s+$)', '', regex=True, inplace=True)
>>> df
   0   1
0  a  10
1  c   5

But it should be faster to do it like this:

>>> df[0] = df[0].str.strip()

EDIT:

The internal log is a circular buffer in memory. There are actually a few such circular buffers for each of: radio, events, main. The default is main.

To obtain a copy of a buffer, one technique involves executing a command on the device and obtaining the output as a string variable.

SendLog is an open source App which does just this: http://www.l6n.org/android/sendlog.shtml

The key is to run logcat on the device in the embedded OS. It's not as hard as it sounds, just check out the open source app in the link.

If you set CURLINFO_HEADER_OUT to true, outgoing headers are available in the array returned by curl_getinfo(), under request_header key:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://foo.com/bar");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "someusername:secretpassword");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);

curl_exec($ch);

$info = curl_getinfo($ch);
print_r($info['request_header']);

This will print:

GET /bar HTTP/1.1
Authorization: Basic c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk
Host: foo.com
Accept: */*

Note the auth details are base64-encoded:

echo base64_decode('c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk');
// prints: someusername:secretpassword

Also note that username and password need to be percent-encoded to escape any URL reserved characters (/, ?, &, : and so on) they might contain:

curl_setopt($ch, CURLOPT_USERPWD, urlencode($username).':'.urlencode($password));

No, how you are doing it is correct.

The most Pythonic way to check the type of an object is... not to check it.

Since Python encourages Duck Typing, you should just try...except to use the object's methods the way you want to use them. So if your function is looking for a writable file object, don't check that it's a subclass of file, just try to use its .write() method!

Of course, sometimes these nice abstractions break down and isinstance(obj, cls) is what you need. But use sparingly.

This way worked for me when adding random data to MySql table using a python script.
First install the following packages using the below commands

pip install mysql-connector-python<br>
pip install random

import mysql.connector
import random

from datetime import date


start_dt = date.today().replace(day=1, month=1).toordinal()
end_dt = date.today().toordinal()

mydb = mysql.connector.connect(
    host="localhost",
    user="root",
    password="root",
    database="your_db_name"
)

mycursor = mydb.cursor()

sql_insertion = "INSERT INTO customer (name,email,address,dateJoined) VALUES (%s, %s,%s, %s)"
#insert 10 records(rows)
for x in range(1,11):
    #generate a random date
    random_day = date.fromordinal(random.randint(start_dt, end_dt))
    value = ("customer" + str(x),"customer_email" + str(x),"customer_address" + str(x),random_day)
    mycursor.execute(sql_insertion , value)

mydb.commit()

print("customer records inserted!")

Following is a sample output of the insertion

cid       |  name      |  email           |    address        |  dateJoined  |

1         | customer1  |  customer_email1 | customer_address1 |  2020-11-15  |
2         | customer2  |  customer_email2 | customer_address2 |  2020-10-11  |
3         | customer3  |  customer_email3 | customer_address3 |  2020-11-17  |
4         | customer4  |  customer_email4 | customer_address4 |  2020-09-20  |
5         | customer5  |  customer_email5 | customer_address5 |  2020-02-18  |

Listed are the steps that could rectify the error:

1. Press Windows+R
2. Type services.msc and strike Enter
3. Find all services
4. Starting with ora start these services and wait!!
5. When your server specific service is initialized (in my case it was orcl)
6. Now run mysql or whatever you are using and start coding.P

Peeskillet's lame tutorial for working with JTables in Netbeans GUI Builder

• Set the table column headers
  1. Highglight the table in the design view then go to properties pane on the very right. Should be a tab that says "Properties". Make sure to highlight the table and not the scroll pane surrounding it, or the next step wont work
  2. Click on the ... button to the right of the property model. A dialog should appear.
  3. Set rows to 0, set the number of columns you want, and their names.

• Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row

  1. Right-click on the button and select Events -> Action -> actionPerformed

  2. You should see code like the following auto-generated

     private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
     

• The jTable1 will have a DefaultTableModel. You can add rows to the model with your data

  private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
      String data1 = something1.getSomething();
      String data2 = something2.getSomething();
      String data3 = something3.getSomething();
      String data4 = something4.getSomething();
  
      Object[] row = { data1, data2, data3, data4 };
  
      DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
  
      model.addRow(row);
  
      // clear the entries.
  }
  

So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.

Just need to set the value property in a convenient place (such as InitializeComponent()):

    dateTimePicker1.Value = DateTime.Today.AddDays(-1);

What you are asking is pretty straight forward

1. execute query against your db to get resultset or use API to get the resultset

2. loop through the resultset or simply the result using php

3. In each iteration simply format the output as an element

Q) Code was working fine in Intellj but failing in command line.

Sol) Add dependencies of jersey as a direct dependency rather than a transient one.

Reasoning: Since, it was working fine with IntelliJ, dependencies are correctly configured.

1. Get required dependencies by one of the following:

   1. check for the IntelliJ running command. Stackoverflow-link
   2. List dependencies from maven mvn dependency:tree

2. Now, add those problematic jersey dependencies explicitly.

A simple explanation that made it more clear to me is:

When you deploy your app, modules in dependencies need to be installed or your app won't work. Modules in devDependencies don't need to be installed on the production server since you're not developing on that machine. link

I had to add "Current" using .NET 4.5:

HttpContext.Current.Server.ScriptTimeout = 300;

In EF Core you no longer can execute "free" raw sql. You are required to define a POCO class and a DbSet for that class. In your case you will need to define Rank:

var ranks = DbContext.Ranks
   .FromSql("SQL_SCRIPT OR STORED_PROCEDURE @p0,@p1,...etc", parameters)
   .AsNoTracking().ToList();

As it will be surely readonly it will be useful to include the .AsNoTracking() call.

EDIT - Breaking change in EF Core 3.0:

DbQuery() is now obsolete, instead DbSet() should be used (again). If you have a keyless entity, i.e. it don't require primary key, you can use HasNoKey() method:

ModelBuilder.Entity<SomeModel>().HasNoKey()

If you find that PIL has problems on some platforms, using a native image viewer may help.

img.save("tmp.png") #Save the image to a PNG file called tmp.png.

For MacOS:

import os
os.system("open tmp.png") #Will open in Preview.

For most GNU/Linux systems with X.Org and a desktop environment:

import os
os.system("xdg-open tmp.png")

For Windows:

import os
os.system("powershell -c tmp.png")

Generally, it's a very good practice to keep it very close.

In some cases, there will be a consideration such as performance which justifies pulling the variable out of the loop.

In your example, the program creates and destroys the string each time. Some libraries use a small string optimization (SSO), so the dynamic allocation could be avoided in some cases.

Suppose you wanted to avoid those redundant creations/allocations, you would write it as:

for (int counter = 0; counter <= 10; counter++) {
   // compiler can pull this out
   const char testing[] = "testing";
   cout << testing;
}

or you can pull the constant out:

const std::string testing = "testing";
for (int counter = 0; counter <= 10; counter++) {
   cout << testing;
}

Do most compilers realize that the variable has already been declared and just skip that portion, or does it actually create a spot for it in memory each time?

It can reuse the space the variable consumes, and it can pull invariants out of your loop. In the case of the const char array (above) - that array could be pulled out. However, the constructor and destructor must be executed at each iteration in the case of an object (such as std::string). In the case of the std::string, that 'space' includes a pointer which contains the dynamic allocation representing the characters. So this:

for (int counter = 0; counter <= 10; counter++) {
   string testing = "testing";
   cout << testing;
}

would require redundant copying in each case, and dynamic allocation and free if the variable sits above the threshold for SSO character count (and SSO is implemented by your std library).

Doing this:

string testing;
for (int counter = 0; counter <= 10; counter++) {
   testing = "testing";
   cout << testing;
}

would still require a physical copy of the characters at each iteration, but the form could result in one dynamic allocation because you assign the string and the implementation should see there is no need to resize the string's backing allocation. Of course, you wouldn't do that in this example (because multiple superior alternatives have already been demonstrated), but you might consider it when the string or vector's content varies.

So what do you do with all those options (and more)? Keep it very close as a default -- until you understand the costs well and know when you should deviate.

To complement about to get more info about a specific view

Even with the two valid answers

SHOW FULL TABLES IN your_db_name WHERE TABLE_TYPE LIKE 'VIEW';

SELECT TABLE_SCHEMA, TABLE_NAME 
FROM information_schema.TABLES 
WHERE TABLE_TYPE LIKE 'VIEW' AND TABLE_SCHEMA LIKE 'your_db_name';

You can apply the following (I think is better):

SELECT TABLE_SCHEMA, TABLE_NAME 
FROM information_schema.VIEWS 
WHERE TABLE_SCHEMA LIKE 'your_db_name';

is better work directly with information_schema.VIEWS (observe now is VIEWS and not TABLES anymore), thus you can retrieve more data, use DESC VIEWS for more details:

+----------------------+---------------------------------+------+-----+---------+-------+
| Field                | Type                            | Null | Key | Default | Extra |
+----------------------+---------------------------------+------+-----+---------+-------+
| TABLE_CATALOG        | varchar(64)                     | YES  |     | NULL    |       |
| TABLE_SCHEMA         | varchar(64)                     | YES  |     | NULL    |       |
| TABLE_NAME           | varchar(64)                     | YES  |     | NULL    |       |
| VIEW_DEFINITION      | longtext                        | YES  |     | NULL    |       |
| CHECK_OPTION         | enum('NONE','LOCAL','CASCADED') | YES  |     | NULL    |       |
| IS_UPDATABLE         | enum('NO','YES')                | YES  |     | NULL    |       |
| DEFINER              | varchar(93)                     | YES  |     | NULL    |       |

| CHARACTER_SET_CLIENT | varchar(64)                     | NO   |     | NULL    |       |
| COLLATION_CONNECTION | varchar(64)                     | NO   |     | NULL    |       |
+----------------------+---------------------------------+------+-----+---------+-------+

For example observe the VIEW_DEFINITION field, thus you can use in action:

SELECT TABLE_SCHEMA, TABLE_NAME, VIEW_DEFINITION 
FROM information_schema.VIEWS 
WHERE TABLE_SCHEMA LIKE 'your_db_name';

Of course you have more fields available for your consideration.

That is the correct event. Maybe it's not wired up correctly?

<TabControl SelectionChanged="TabControl_SelectionChanged">
    <TabItem Header="One"/>
    <TabItem Header="2"/>
    <TabItem Header="Three"/>
</TabControl>

in the codebehind....

private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    int i = 34;
}

if I set a breakpoint on the i = 34 line, it ONLY breaks when i change tabs, even when the tabs have child elements and one of them is selected.

If you are using Xamarin to develop an iOS application, here is the C# equivalent to make a phone call within your application:

string phoneNumber = "1231231234";
NSUrl url = new NSUrl(string.Format(@"telprompt://{0}", phoneNumber));
UIApplication.SharedApplication.OpenUrl(url);

There are quite a few options that can be used: (both tested).

Here are two ways.

header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');

or: (note the escaped double-quotes). The same need to be use when assigning a name to it.

<?php

echo "<iframe src=\"file.pdf\" width=\"100%\" style=\"height:100%\"></iframe>";

?>

I.e.: name="myiframe" id="myiframe"

would need to be changed to:

name=\"myiframe\" id=\"myiframe\" inside PHP.

Be sure to have a look at: this answer on SO for more options on the subject.

Footnote: There are known issues when trying to view PDF files in Windows 8. Installing Adobe Acrobat Reader is a better method to view these types of documents if no browser plug-ins are installed.

In addition to the above comments, I would like to add few points about Views.

1. Views can be used to hide complexity. Imagine a scenario where 5 people are working on a project but only one of them is too good with database stuff like complex joins. In such scenario, he can create Views which can be easily queried by other team members as they are querying any single table.
2. Security can be easily implemented by Views. Suppose we a Table Employee which contains sensitive columns like Salary, SSN number. These columns are not supposed to be visible to the users who are not authorized to view them. In such case, we can create a View selecting the columns in a table which doesn't require any authorization like Name, Age etc, without exposing sensitive columns (like Salary etc. we mentioned before). Now we can remove permission to directly query the table Employee and just keep the read permission on the View. In this way, we can implement security using Views.

Well its a sequential process. The Request first treat by FrontController and then moves towards our own customize controller with @Controller annotation.

but our controller method is binding bean using modelattribute and we are also performing few validations on bean values.

so instead of moving the request to our controller class, FrontController moves it towards one interceptor which creates the temp object of our bean and the validate the values. if validation successful then bind the temp obj values with our actual bean which is stored in @ModelAttribute otherwise if validation fails it does not bind and moves the resp towards error page or wherever u want.

Just use Val():

currentLoad = Int(Val([f4]))

Now currentLoad has a integer value, zero if [f4] is not numeric.

You can't extend Enum as it's a static class. You can only extend instances of a type. With this in mind, you're going to have to create a static method yourself to do this; the following should work when combined with your existing method GetDescription:

public static class EnumHelper
{
    public static T GetEnumFromString<T>(string value)
    {
        if (Enum.IsDefined(typeof(T), value))
        {
            return (T)Enum.Parse(typeof(T), value, true);
        }
        else
        {
            string[] enumNames = Enum.GetNames(typeof(T));
            foreach (string enumName in enumNames)
            {  
                object e = Enum.Parse(typeof(T), enumName);
                if (value == GetDescription((Enum)e))
                {
                    return (T)e;
                }
            }
        }
        throw new ArgumentException("The value '" + value 
            + "' does not match a valid enum name or description.");
    }
}

And the usage of it would be something like this:

Animal giantPanda = EnumHelper.GetEnumFromString<Animal>("Giant Panda");

1. Download the plugin.
2. Inside Jenkins: Manage Jenkins ? Manage Plugins ? There is a tab called Advanced and on that page there is an option to upload a plugin (the extension of the file must be hpi).

Sometimes, when you download plugins you may get (.zip) files then just rename with (.hpi) and use the UI to install the plugin.

I'd use standard javascript:

for (var m in myMap){
    for (var i=0;i<myMap[m].length;i++){
    ... do something with myMap[m][i] ...
    }
} 

Note the different ways of treating objects and arrays.

It took me months of googling to find a solution for this issue. You don't need to install a virtual environment running a 32-bit version of Windows to run a program with a 16-bit installer on 64-bit Windows. If the program itself is 32-bit, and just the installer is 16-bit, here's your answer.

There are ways to modify a 16-bit installation program to make it 32-bit so it will install on 64-bit Windows 7. I found the solution on this site:

http://www.reactos.org/forum/viewtopic.php?f=22&t=10988

In my case, the installation program was InstallShield 5.X. The issue was that the setup.exe program used by InstallShield 5.X is 16-bit. First I extracted the installation program contents (changed the extension from .exe to .zip, opened it and extracted). I then replaced the original 16-bit setup.exe, located in the disk1 folder, with InstallShield's 32-bit version of setup.exe (download this file from the site referenced in the above link). Then I just ran the new 32-bit setup.exe in disk1 to start the installation and my program installed and runs perfectly on 64-bit Windows.

You can also repackage this modified installation, so it can be distributed as an installation program, using a free program like Inno Setup 5.

use like this :-

gridview1.DataSource = ds.Tables[0]; <-- Use index or your table name which you want to bind
gridview1.DataBind();

I hope it helps!!

You can test the unsigned-apk only on Emulator. And as its step of application deployment and distribution, you should read this article atleast once, i suggest: http://developer.android.com/guide/publishing/app-signing.html.

For your question, you can find the below line in above article:

All applications must be signed. The system will not install an application that is not signed.

so you have to have signed-apk before the distribution of your application.

To generate Signed-apk of your application, there is a simple wizard procedure, click on File -> Export -> Android -> Export Android application.

I had the same problem because I set the following in Catalina.sh of my tomcat:

JAVA_OPTS="$JAVA_OPTS -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999" 

After removing it, my tomcat worked well.

Hope help you.

In this scenario, I prefer to create new branches for each issue. I use a prefix temp/ so I know that I can delete these branches later.

git checkout -b temp/bug1

Stage the files that fix bug1 and commit them.

git checkout -b temp/bug2

You can then cherry pick the commits from the respective branches as require and submit a pull request.

Use pyenv instead to install and switch between versions of Python. I've been using rbenv for years which does the same thing, but for Ruby. Before that it was hell managing versions.

Consult pyenv's github page for installation instructions. Basically it goes like this: - Install pyenv using homebrew. brew install pyenv - Add a function to the end of your shell startup script so pyenv can do it's magic. echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n eval "$(pyenv init -)"\nfi' >> ~/.bash_profile

• Use pyenv to install however many different versions of Python you need. pyenv install 3.7.7.
• Set the default (global) version to a modern version you just installed. pyenv global 3.7.7.
• If you work on a project that needs to use a different version of python, look into pyevn local. This creates a file in your project's folder that specifies the python version. Pyenv will look override the global python version with the version in that file.

As @kirbyfan64sos notes in a comment, /home is NOT your home directory (a.k.a. home folder):

The fact that /home is an absolute, literal path that has no user-specific component provides a clue.

While /home happens to be the parent directory of all user-specific home directories on Linux-based systems, you shouldn't even rely on that, given that this differs across platforms: for instance, the equivalent directory on macOS is /Users.

What all Unix platforms DO have in common are the following ways to navigate to / refer to your home directory:

• Using cd with NO argument changes to your home dir., i.e., makes your home dir. the working directory.
  • e.g.: cd # changes to home dir; e.g., '/home/jdoe'

• Unquoted ~ by itself / unquoted ~/ at the start of a path string represents your home dir. / a path starting at your home dir.; this is referred to as tilde expansion (see man bash)
  • e.g.: echo ~ # outputs, e.g., '/home/jdoe'

• $HOME - as part of either unquoted or preferably a double-quoted string - refers to your home dir. HOME is a predefined, user-specific environment variable:
  • e.g.: cd "$HOME/tmp" # changes to your personal folder for temp. files

Thus, to create the desired folder, you could use:

mkdir "$HOME/bin"  # same as: mkdir ~/bin

Note that most locations outside your home dir. require superuser (root user) privileges in order to create files or directories - that's why you ran into the Permission denied error.

<input name="amount" type="text" value="Only number in here"/> 

<script>
    $('input[name=amount]').keyup(function(){
        $(this).val($(this).val().replace(/[^\d]/,''));
    });
</script>

Consider the Switch Function as an alternative to multiple IIf() expressions. It will return the value from the first expression/value pair where the expression evaluates as True, and ignore any remaining pairs. The concept is similar to the SELECT ... CASE approach you referenced but which is not available in Access SQL.

If you want to display a calculated field as commission:

SELECT
    Switch(
        OpeningBalance < 5001, 20,
        OpeningBalance < 10001, 30,
        OpeningBalance < 20001, 40,
        OpeningBalance >= 20001, 50
        ) AS commission
FROM YourTable;

If you want to store that calculated value to a field named commission:

UPDATE YourTable
SET commission =
    Switch(
        OpeningBalance < 5001, 20,
        OpeningBalance < 10001, 30,
        OpeningBalance < 20001, 40,
        OpeningBalance >= 20001, 50
        );

Either way, see whether you find Switch() easier to understand and manage. Multiple IIf()s can become mind-boggling as the number of conditions grows.

Edit: As stated in the comments, the following solution applies to PowerShell V1 only.

See this blog post on "Technical Adventures of Adam Weigert" for details on how to implement this.

Example usage (copy/paste from Adam Weigert's blog):

Try {
    echo " ::Do some work..."
    echo " ::Try divide by zero: $(0/0)"
} -Catch {
    echo "  ::Cannot handle the error (will rethrow): $_"
    #throw $_
} -Finally {
    echo " ::Cleanup resources..."
}

Otherwise you'll have to use exception trapping.

It's a SQL Compact database. You need to define what you mean by "Open". You can open it via code with the SqlCeConnection so you can write your own tool/app to access it.

Visual Studio can also open the files directly if was created with the right version of SQL Compact.

There are also some third-party tools for manipulating them.

In addition to what have been said, the bind() method allows an object to borrow a method from another object without making a copy of that method. This is known as function borrowing in JavaScript.

The new Android Design Support Library adds TabLayout, providing a tab implementation that matches the material design guidelines for tabs. A complete walkthrough of how to implement Tabs and ViewPager can be found in this video

Now deprecated: The PagerTabStrip is part of the support library (and has been for some time) and serves as a direct replacement. If you prefer the newer Google Play style tabs, you can use the PagerSlidingTabStrip library or modify either of the Google provided examples SlidingTabsBasic or SlidingTabsColors as explained in this Dev Bytes video.

Here is a way to transform a date string with a time of day to a date object. For example to convert "20/10/2020 18:11:25" ("DD/MM/YYYY HH:MI:SS" format) to a date object

    function newUYDate(pDate) {
      let dd = pDate.split("/")[0].padStart(2, "0");
      let mm = pDate.split("/")[1].padStart(2, "0");
      let yyyy = pDate.split("/")[2].split(" ")[0];
      let hh = pDate.split("/")[2].split(" ")[1].split(":")[0].padStart(2, "0");
      let mi = pDate.split("/")[2].split(" ")[1].split(":")[1].padStart(2, "0");
      let secs = pDate.split("/")[2].split(" ")[1].split(":")[2].padStart(2, "0");
    
      mm = (parseInt(mm) - 1).toString(); // January is 0
    
      return new Date(yyyy, mm, dd, hh, mi, secs);
    }

There are two issues I encountered with the other suggestions

1) Drive mappings are not supported if you run the powershell under task scheduler

2) You may get Access is denied errors errors trying to used "get-WmiObject" on remote computers (depending on your infrastructure setup, of course)

The alternative that doesn't suffer from these issues is to use GetDiskFreeSpaceEx with a UNC path:

function getDiskSpaceInfoUNC($p_UNCpath, $p_unit = 1tb, $p_format = '{0:N1}')
{
    # unit, one of --> 1kb, 1mb, 1gb, 1tb, 1pb
    $l_typeDefinition = @' 
        [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] 
        [return: MarshalAs(UnmanagedType.Bool)] 
        public static extern bool GetDiskFreeSpaceEx(string lpDirectoryName, 
            out ulong lpFreeBytesAvailable, 
            out ulong lpTotalNumberOfBytes, 
            out ulong lpTotalNumberOfFreeBytes); 
'@
    $l_type = Add-Type -MemberDefinition $l_typeDefinition -Name Win32Utils -Namespace GetDiskFreeSpaceEx -PassThru

    $freeBytesAvailable     = New-Object System.UInt64 # differs from totalNumberOfFreeBytes when per-user disk quotas are in place
    $totalNumberOfBytes     = New-Object System.UInt64
    $totalNumberOfFreeBytes = New-Object System.UInt64

    $l_result = $l_type::GetDiskFreeSpaceEx($p_UNCpath,([ref]$freeBytesAvailable),([ref]$totalNumberOfBytes),([ref]$totalNumberOfFreeBytes)) 

    $totalBytes     = if($l_result) { $totalNumberOfBytes    /$p_unit } else { '' }
    $totalFreeBytes = if($l_result) { $totalNumberOfFreeBytes/$p_unit } else { '' }

    New-Object PSObject -Property @{
        Success   = $l_result
        Path      = $p_UNCpath
        Total     = $p_format -f $totalBytes
        Free      = $p_format -f $totalFreeBytes
    } 
}

From the documentation for FileSystemWatcher:

The OnCreated event is raised as soon as a file is created. If a file is being copied or transferred into a watched directory, the OnCreated event will be raised immediately, followed by one or more OnChanged events.

So, if the copy fails, (catch the exception), add it to a list of files that still need to be moved, and attempt the copy during the OnChanged event. Eventually, it should work.

Something like (incomplete; catch specific exceptions, initialize variables, etc):

public static void listener_Created(object sender, FileSystemEventArgs e)
{
    Console.WriteLine
            (
                "File Created:\n"
               + "ChangeType: " + e.ChangeType
               + "\nName: " + e.Name
               + "\nFullPath: " + e.FullPath
            );
    try {
        File.Copy(e.FullPath, @"D:\levani\FolderListenerTest\CopiedFilesFolder\" + e.Name);
    }
    catch {
        _waitingForClose.Add(e.FullPath);
    }
    Console.Read();
}

public static void listener_Changed(object sender, FileSystemEventArgs e)
{
     if (_waitingForClose.Contains(e.FullPath))
     {
          try {
              File.Copy(...);
              _waitingForClose.Remove(e.FullPath);
          }
          catch {}
     }

}

import logging

logging.basicConfig(filename="f.log" filemode='w', level=logging.INFO,
                    format = "%(logger_name)s %(color)s  %(message)s %(endColor)s")


class Logger(object):
    __GREEN = "\033[92m"
    __RED = '\033[91m'
    __ENDC = '\033[0m'

    def __init__(self, name):
        self.logger = logging.getLogger(name)
        self.extra={'logger_name': name, 'endColor': self.__ENDC, 'color': self.__GREEN}


    def info(self, msg):
        self.extra['color'] = self.__GREEN
        self.logger.info(msg, extra=self.extra)

    def error(self, msg):
        self.extra['color'] = self.__RED
        self.logger.error(msg, extra=self.extra)

Usage

Logger("File Name").info("This shows green text")

You need to look at the explain plans, but unless there is an INDEX or PARTITION on COL_A, you are looking at a FULL TABLE SCAN on both tables.

With that in mind, your first example is throwing out some of the data as it does the FULL TABLE SCAN. That result is being sorted by the UNION, then duplicate data is dropped. This gives you your result set.

In the second example, you are pulling the full contents of both tables. That result is likely to be larger. So the UNION is sorting more data, then dropping the duplicate stuff. Then the filter is being applied to give you the result set you are after.

As a general rule, the earlier you filter away data, the smaller the data set, and the faster you will get your results. As always, your milage may vary.

You can do this in a try and catch block:

try:
    if val is None:
        print("null")
except NameError:
    # throw an exception or do something else

Add this in your module.ts,

declarations: [
  AppComponent,
  ConfirmComponent
]

if ConfirmComponent is in another module, you need to export it there thus you can use it outside, add:

exports: [ ConfirmComponent ]

---Update Angular 9 or Angular 8 with Ivy explicitly enabled---

Entry Components With Ivy are not required anymore and now are deprecated

---for Angular 9 and 8 with Ivy disabled---

In the case of a dynamically loaded component and in order for a ComponentFactory to be generated, the component must also be added to the module’s entryComponents:

declarations: [
  AppComponent,
  ConfirmComponent
],
entryComponents: [ConfirmComponent],

according to the definition of entryComponents

Specifies a list of components that should be compiled when this module is defined. For each component listed here, Angular will create a ComponentFactory and store it in the ComponentFactoryResolver.

You can also try using parameters directive for making your build parameterized and accessing parameters:

Doc: Pipeline syntax: Parameters

Example:

pipeline{

agent { node { label 'test' } }
options { skipDefaultCheckout() }

parameters {
    string(name: 'suiteFile', defaultValue: '', description: 'Suite File')
}
stages{

    stage('Initialize'){

        steps{

          echo "${params.suiteFile}"

        }
    }
 }

Try With reload: true?

Couldn't figure out what was going on for the longest time -- turns out I was fooling myself. If you're certain that things are written correctly and you will to use the same state, try reload: true:

.state('status.item', {
    url: '/:id',
    views: {...}
}

$state.go('status.item', { id: $scope.id }, { reload: true });

Hope this saves you time!

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

$(Split-Path "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv" -leaf)

You need

/^[a-zA-Z]+$/

Currently, you are matching a single character at the start of the input. If your goal is to match letter characters (one or more) from start to finish, then you need to repeat the a-z character match (using +) and specify that you want to match all the way to the end (via $)

Yes, you could use either the JavaScript setTimeout() method or setInterval() method to invoke the code that you would like to run. Here's how you might do it with setTimeout:

function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }
  });
  setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}

$(document).ready(function() {
  // run the first time; all subsequent calls will take care of themselves
  setTimeout(executeQuery, 5000);
});

use the command prompt, as suggested. I figured out why explorer is so slow a while ago, it gives you an estimate of how long it will take to delete the files/folders. To do this, it has to scan the number of items and the size. This takes ages, hence the ridiculous wait with large folders.

Also, explorer will stop if there is a particular problem with a file,

This might not be what you're looking for, but here's something I did for an assignment:

$" = ", ";
print "@ArrayName\n";

Just type import pdb in jupyter notebook, and then use this cheatsheet to debug. It's very convenient.

c --> continue, s --> step, b 12 --> set break point at line 12 and so on.

Some useful links: Python Official Document on pdb, Python pdb debugger examples for better understanding how to use the debugger commands.

Some useful screenshots:

In addition to the provided answer, there are more details to navigate. From the function's comments:

/**
 * Navigate based on the provided array of commands and a starting point.
 * If no starting route is provided, the navigation is absolute.
 *
 * Returns a promise that:
 * - resolves to 'true' when navigation succeeds,
 * - resolves to 'false' when navigation fails,
 * - is rejected when an error happens.
 *
 * ### Usage
 *
 * ```
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route});
 *
 * // Navigate without updating the URL
 * router.navigate(['team', 33, 'user', 11], {relativeTo: route, skipLocationChange: true});
 * ```
 *
 * In opposite to `navigateByUrl`, `navigate` always takes a delta that is applied to the current
 * URL.
 */

The Router Guide has more details on programmatic navigation.

To break out of multiple nested loops, without refactoring into a function, make use of a "simulated goto statement" with the built-in StopIteration exception:

try:
    for outer in range(100):
        for inner in range(100):
            if break_early():
                raise StopIteration

except StopIteration: pass

See this discussion on the use of goto statements for breaking out of nested loops.

Put this at the top of your .py file (for python 2.x)

#!/usr/bin/env python 

or for python 3.x

#!/usr/bin/env python3

This should look up the python environment, without it, it will execute the code as if it were not python code, but straight to the CLI. If you need to specify a manual location of python environment put

#!/#path/#to/#python

These sections of the MSDN documentation deal with most of your questions: http://msdn.microsoft.com/en-us/library/8bs2ecf4(VS.71).aspx

I hope this helps.

Have a button on list and let it onclick feature in xml like to get postion first

public void OnClickButton(View V){
  final int postion = listView.getPositionForView(V);
    System.out.println("postion selected is : "+postion);
Delete(postion);

}
public void Delete(int position){
    if (adapter.getCount() > 0) {

        //Log.d("largest no is",""+largestitemno);
        //deleting the latest added by subtracting one 1 
        comment = (GenrricStoring) adapter.getItem(position);
        //Log.d("Deleting item is: ",""+comment);
        dbconnection.deleteComment(comment);
        List<GenrricStoring> values = dbconnection.getAllComments();
        //updating the content on the screen
        this.adapter = new UserItemAdapter(this, android.R.layout.simple_list_item_1, values);
        listView.setAdapter(adapter);
    }
    else
    {
        int duration = Toast.LENGTH_SHORT;
        //for showing nothing is left in the list
        Toast toast = Toast.makeText(getApplicationContext(),"Db is empty", duration);
        toast.setGravity(Gravity.CENTER, 0, 0);

        toast.show();
    }

}

So they could be used one day if the language designers felt the need.

Also, if programmers from languages that do have these keywords (eg. C, C++) use them by mistake, then the Java compiler can give a useful error message.

Or maybe it was just to stop programmers using goto :)

Change android:stretchColumns value to *.

Value 0 means stretch the first column. Value 1 means stretch the second column and so on.

Value * means stretch all the columns.

Regarding storing credentials, I use two functions(that are normally in a module that is loaded from my profile):

#=====================================================================
# Get-MyCredential
#=====================================================================
function Get-MyCredential
{
param(
$CredPath,
[switch]$Help
)
$HelpText = @"

    Get-MyCredential
    Usage:
    Get-MyCredential -CredPath `$CredPath

    If a credential is stored in $CredPath, it will be used.
    If no credential is found, Export-Credential will start and offer to
    Store a credential at the location specified.

"@
    if($Help -or (!($CredPath))){write-host $Helptext; Break}
    if (!(Test-Path -Path $CredPath -PathType Leaf)) {
        Export-Credential (Get-Credential) $CredPath
    }
    $cred = Import-Clixml $CredPath
    $cred.Password = $cred.Password | ConvertTo-SecureString
    $Credential = New-Object System.Management.Automation.PsCredential($cred.UserName, $cred.Password)
    Return $Credential
}

And this one:

#=====================================================================
# Export-Credential
# Usage: Export-Credential $CredentialObject $FileToSaveTo
#=====================================================================
function Export-Credential($cred, $path) {
      $cred = $cred | Select-Object *
      $cred.password = $cred.Password | ConvertFrom-SecureString
      $cred | Export-Clixml $path
}

You use it like this:

$Credentials = Get-MyCredential (join-path ($PsScriptRoot) Syncred.xml)

If the credential file doesnt exist, you will be prompted the first time, at that point it will store the credentials in an encrypted string inside an XML file. The second time you run that line, the xmlfile is there and will be opened automatically.

To run Android envirorment on low configuration machine.

1. Close the uncessesory web tabs in browser
2. For Antivirus users, exclude the build folder which is auto generated
3. Android studio have 1.2 Gb default heap can decrease to 512 MB

Help > Edit custom VM options

studio.vmoptions
 -Xmx512m

Layouts performace will be speed up

4. For Gradle one of the core component in Android studio Mkae sure like right now 3.0beta is latest one

Below tips can affect the code quality so please use with cautions:

1. Studio contain Power safe Mode when turned on it will close background operations that lint , code complelitions and so on.

2. You can run manually lint check when needed ./gradlew lint

3. Most of are using Android emulators on average it consume 2 GB RAM so if possible use actual Android device these will reduce your resource load on your computer. Alternatively you can reduce the RAM of the emulator and it will automatically reduce the virtual memory consumption on your computer. you can find this in virtual device configuration and advance setting.

4. Gradle offline mode is a feature for bandwidth limited users to disable the downloading of build dependencies. It will reduce the background operation that will help to increase the performance of Android studio.

5. Android studio offers an optimization to compile multiple modules in parallel. On low RAM machines this feature will likely have a negative impact on the performance. You can disable it in the compiler settings dialog.

Create a function in a package and return a SYS_REFCURSOR:

FUNCTION Function1 return SYS_REFCURSOR IS 
       l_cursor SYS_REFCURSOR;
       BEGIN
          open l_cursor for SELECT foo,bar FROM foobar; 
          return l_cursor; 
END Function1;

Facebook prefers that you load their SDK asynchronously so that it doesn't block any other scripts that you need for your page but due to the iframe there's a chance that the console tries to call a method on the FB object before the FB object is completely created even though FB is only called in the fbAsyncInit function.
Try loading the javascript synchronously and you shouldn't get the error anymore. To do this you can copy and paste the code that Facebook provides and place it in an external .js file and then include that .js file in a <script> tag in the <head> of your page. If you must load their SDK asynchronously then check for FB to be created first before calling the init function.

You could try something like this as well

<a href="#" onclick="one(); two();" >click</a>

<script type="text/javascript">
    function one(){
        alert('test');
    }

    function two(){
        alert('test2');
    }
</script>

If you are getting the error as

Although this is somewhat old I would like to add a slightly improved version that really changes column order. Here are the steps (assuming we have a table TAB1 with columns COL1, COL2, COL3):

1. Add new column to table TAB1:

alter table TAB1 add (NEW_COL number);

1. "Copy" table to temp name while changing the column order AND rename the new column:

create table tempTAB1 as select NEW_COL as COL0, COL1, COL2, COL3 from TAB1;

1. drop existing table:

drop table TAB1;

1. rename temp tablename to just dropped tablename:

rename tempTAB1 to TAB1;

Yes, definitely don't write your own algorithm. Java has lots of cryptography APIs.

If the OS you are installing upon has a keystore, then you could use that to store your crypto keys that you will need to encrypt and decrypt the sensitive data in your configuration or other files.

If you add -Wl,--start-group to the linker flags it does not care which order they're in or if there are circular dependencies.

On Qt this means adding:

QMAKE_LFLAGS += -Wl,--start-group

Saves loads of time messing about and it doesn't seem to slow down linking much (which takes far less time than compilation anyway).

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.

You should definitely avoid using <jsp:...> tags. They're relics from the past and should always be avoided now.

Use the JSTL.

Now, wether you use the JSTL or any other tag library, accessing to a bean property needs your bean to have this property. A property is not a private instance variable. It's an information accessible via a public getter (and setter, if the property is writable). To access the questionPaperID property, you thus need to have a

public SomeType getQuestionPaperID() {
    //...
}

method in your bean.

Once you have that, you can display the value of this property using this code :

<c:out value="${Questions.questionPaperID}" />

or, to specifically target the session scoped attributes (in case of conflicts between scopes) :

<c:out value="${sessionScope.Questions.questionPaperID}" />

Finally, I encourage you to name scope attributes as Java variables : starting with a lowercase letter.

This is how it is done using the fluent interface of the op4j Java library (1.1. was released Dec '10) :-

List<String> names = Op.onListFor("Ryan", "Julie", "Bob").get();

It's a very cool library that saves you a tonne of time.

I have found a solution. It is just a workaround to my problem but currently the only solution.

ViewPager PagerAdapter not updating the View

Does anyone know whether this is a bug or not?

In SBT 0.13 and above, you can use the sbtVersion task (as pointed out by @steffen) or about command (as pointed out by @mark-harrah)

There's a difference how the sbtVersion task works in and outside a SBT project. When in a SBT project, sbtVersion displays the version of SBT used by the project and its subprojects.

$ sbt sbtVersion

It's set in project/build.properties:

jacek:~/oss/scalania
$ cat project/build.properties

The same task executed outside a SBT project shows the current version of the executable itself.

Displays basic information about sbt and the build.

For the sbtVersion setting, the inspect command can help.

The version setting that people seem to expect to inspect to know the SBT version is to set The version/revision of the current module.

When used in a SBT project the tasks/settings may show different outputs.

With a different example:

Consider this is the string and pattern to be searched for is 'cat':

text = "catmania thiscat thiscatmaina";

Now definitions,

'\b' finds/matches the pattern at the beginning or end of each word.

'\B' does not find/match the pattern at the beginning or end of each word.

Different Cases:

Case 1: At the beginning of each word

result = text.replace(/\bcat/g, "ct");

Now, result is "ctmania thiscat thiscatmaina"

Case 2: At the end of each word

result = text.replace(/cat\b/g, "ct");

Now, result is "catmania thisct thiscatmaina"

Case 3: Not in the beginning

result = text.replace(/\Bcat/g, "ct");

Now, result is "catmania thisct thisctmaina"

Case 4: Not in the end

result = text.replace(/cat\B/g, "ct");

Now, result is "ctmania thiscat thisctmaina"

Case 5: Neither beginning nor end

result = text.replace(/\Bcat\B/g, "ct");

Now, result is "catmania thiscat thisctmaina"

Hope this helps :)

For ExcelDataReader v3.6.0 and above. I struggled a bit to iterate over the Rows. So here's a little more to the above code. Hope it helps for few atleast.

using (var stream = System.IO.File.Open(copyPath, FileMode.Open, FileAccess.Read))
                    {

                        IExcelDataReader excelDataReader = ExcelDataReader.ExcelReaderFactory.CreateReader(stream);

                        var conf = new ExcelDataSetConfiguration()
                        {
                            ConfigureDataTable = a => new ExcelDataTableConfiguration
                            {
                                UseHeaderRow = true
                            }
                        };

                        DataSet dataSet = excelDataReader.AsDataSet(conf);
                        //DataTable dataTable = dataSet.Tables["Sheet1"];
                        DataRowCollection row = dataSet.Tables["Sheet1"].Rows;
                        //DataColumnCollection col = dataSet.Tables["Sheet1"].Columns;

                        List<object> rowDataList = null;
                        List<object> allRowsList = new List<object>();
                        foreach (DataRow item in row)
                        {
                            rowDataList = item.ItemArray.ToList(); //list of each rows
                            allRowsList.Add(rowDataList); //adding the above list of each row to another list
                        }

                    }

ES6 supports now class & static keywords like a charm :

class Foo {
    constructor() {}

    talk() {
        console.log("i am not static");
    }

    static saying() {
        console.log(this.speech);
    }

    static get speech() {
        return "i am static method";
    }

}

Try disabling the xcache or apc modules. Seems to cause a problem with some versions are saving objects to a session variable.

Here is the official documentation. This is also automatically downloaded at step 2.

Below is a really simple way to do it and I've successfully built my app using .NET framework 4.6.1

1. Install ILMerge nuget package either via gui or commandline:

   Install-Package ilmerge
   

2. Verify you have downloaded it. Now Install (not sure the command for this, but just go to your nuget packages): Note: You probably only need to install it for one of your solutions if you have multiple

3. Navigate to your solution folder and in the packages folder you should see 'ILMerge' with an executable:

   \FindMyiPhone-master\FindMyiPhone-master\packages\ILMerge.2.14.1208\tools
   

   

4. Now here is the executable which you could copy over to your \bin\Debug (or whereever your app is built) and then in commandline/powershell do something like below:

   ILMerge.exe myExecutable.exe myDll1.dll myDll2.dll myDlln.dll myNEWExecutable.exe
   

You will now have a new executable with all your libraries in one!

The first part is similar to Constantine, you can get the boolean of which rows are empty*:

In [21]: ne = (df1 != df2).any(1)

In [22]: ne
Out[22]:
0    False
1     True
2     True
dtype: bool

Then we can see which entries have changed:

In [23]: ne_stacked = (df1 != df2).stack()

In [24]: changed = ne_stacked[ne_stacked]

In [25]: changed.index.names = ['id', 'col']

In [26]: changed
Out[26]:
id  col
1   score         True
2   isEnrolled    True
    Comment       True
dtype: bool

Here the first entry is the index and the second the columns which has been changed.

In [27]: difference_locations = np.where(df1 != df2)

In [28]: changed_from = df1.values[difference_locations]

In [29]: changed_to = df2.values[difference_locations]

In [30]: pd.DataFrame({'from': changed_from, 'to': changed_to}, index=changed.index)
Out[30]:
               from           to
id col
1  score       1.11         1.21
2  isEnrolled  True        False
   Comment     None  On vacation

* Note: it's important that df1 and df2 share the same index here. To overcome this ambiguity, you can ensure you only look at the shared labels using df1.index & df2.index, but I think I'll leave that as an exercise.

I took Jezzipin's answer and made it so that if you are scrolled when you refresh the page, the correct size applies. Also removed some stuff that isn't necessarily needed.

function sizer() {
    if($(document).scrollTop() > 0) {
        $('#header_nav').stop().animate({
            height:'40px'
        },600);
    } else {
        $('#header_nav').stop().animate({
            height:'100px'
        },600);
    }
}

$(window).scroll(function(){
    sizer();
});

sizer();

I need this so often that I created a function in my ~/.bashrc file:

chmodf() {
        find $2 -type f -exec chmod $1 {} \;
}
chmodd() {
        find $2 -type d -exec chmod $1 {} \;
}

Now I can use these shortcuts:

chmodd 0775 .
chmodf 0664 .

There are various classes for different size inputs

 :class=>"input-mini"

 :class=>"input-small"

 :class=>"input-medium"

 :class=>"input-large"

 :class=>"input-xlarge"

 :class=>"input-xxlarge"

After much searching a way to show a progress bar just to make the most elegant charging could not find any way that would serve my purpose. Check the actual status of the request showed demaziado complex and sometimes snippets not then worked created a very simple way but it gives me the experience seeking (or almost), follows the code:

$.ajax({
    type : 'GET',
    url : url,
    dataType: 'html',
    timeout: 10000,
    beforeSend: function(){
        $('.my-box').html('<div class="progress"><div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 0%;"></div></div>');
        $('.progress-bar').animate({width: "30%"}, 100);
    },
    success: function(data){  
        if(data == 'Unauthorized.'){
            location.href = 'logout';
        }else{
            $('.progress-bar').animate({width: "100%"}, 100);
            setTimeout(function(){
                $('.progress-bar').css({width: "100%"});
                setTimeout(function(){
                    $('.my-box').html(data);
                }, 100);
            }, 500);
        }
    },
    error: function(request, status, err) {
        alert((status == "timeout") ? "Timeout" : "error: " + request + status + err);
    }
});

After 7 long hours of searching I finally found the way!! None of the above solutions worked, only one of them pointed towards the issue!

If you are on Win7, then your Firewall blocks the SDK Manager from retrieving the addon list. You will have to add "android.bat" and "java.exe" to the trusted files and bingo! everything will start working!!

// main class that everything inherits
class Grandpa 
{
    public function __construct()
    {
        $this->___construct();
    }

    protected function ___construct()
    {
        // grandpa's logic
    }

}

class Papa extends Grandpa
{
    public function __construct()
    {
        // call Grandpa's constructor
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        parent::___construct();
    }
}

note that "___construct" is not some magic name, you can call it "doGrandpaStuff".

On the Mac, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

I launched the Console utility and scrolled down to ~/Library/Logs -> AndroidStudioBeta ->idea.log.1 (or any old log number)

Then I searched for “android.injected.signing.store” and found this from an earlier date:

-Pandroid.injected.signing.store.file=/Users/myuserid/AndroidStudioProjects/keystore/keystore.jks, 
-Pandroid.injected.signing.store.password=mystorepassword, 
-Pandroid.injected.signing.key.alias=myandroidkey, 
-Pandroid.injected.signing.key.password=mykeypassword,

On Windows

you can find your lost key password in below path

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin or ..taskHistory\taskHistory.bin

open the file using appropriate tools e.g. NotePad++ and search with the part of the password that you remember. You will find it definitely. Else, try searching with this string "signingConfig.storePassword".

Note: I have experienced the same and i am able to find it. In case if you didn't find may be you cleared all the cache and temp files.

For code readability reasons I believe returning true/false should:

• be on one line
• be one command
• be easy to remember
• mention the keyword return followed by another keyword (true or false)

My solution is return $(true) or return $(false) as shown:

is_directory()
{
    if [ -d "${1}" ]; then
        return $(true)
    else
        return $(false)
    fi
}

The following code will put the div in the middle of the screen regardless of screen size or div size:

.center-screen {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  text-align: center;_x000D_
  min-height: 100vh;_x000D_
}

 <html>_x000D_
 <head>_x000D_
 </head>_x000D_
 <body>_x000D_
 <div class="center-screen">_x000D_
 I'm in the center_x000D_
 </div>_x000D_
 </body>_x000D_
 </html>

Download the JDK version of the JRE to the installed JRE's and use that instead.
In Eclipse Indigo, if you check the classpath tab on the run configuration for ant, you will see that it defaults to adding the tools.jar from the system. So if you launch Eclipse using Java7 and run an ant build using a separate JRE6 it generates an UnsupportedClassVersionError. When I added the JDK version Eclipse picked up the tools.jar from the JDK and my ant task ran successfully.

If you need to install an older version (for example 0.25):

pod _0.25.0_ install

You'll need to use a static readonly list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T> rather than List<T>.

private static readonly ReadOnlyCollection<string> _metrics =
    new ReadOnlyCollection<string>(new[]
        {
            SourceFile.LOC,
            SourceFile.MCCABE,
            SourceFile.NOM,
            SourceFile.NOA,
            SourceFile.FANOUT,
            SourceFile.FANIN,
            SourceFile.NOPAR,
            SourceFile.NDC,
            SourceFile.CALLS
        });

public static ReadOnlyCollection<string> Metrics
{
    get { return _metrics; }
}

When calling a function that is declared with throws in Swift, you must annotate the function call site with try or try!. For example, given a throwing function:

func willOnlyThrowIfTrue(value: Bool) throws {
  if value { throw someError }
}

this function can be called like:

func foo(value: Bool) throws {
  try willOnlyThrowIfTrue(value)
}

Here we annotate the call with try, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws, because this function could throw an exception (i.e., when willOnlyThrowIfTrue() throws, then foo will automatically rethrow the exception upwards.

If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!.

func bar() {
  try! willOnlyThrowIfTrue(false)
}

This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.

try! is enforced at runtime: if you use try! and the function does end up throwing, then your program's execution will be terminated with a runtime error.

Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()), or sometimes via defered code.

func baz(value: Bool) throws {

  var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
  var data = NSData(contentsOfFile:filePath)

  try willOnlyThrowIfTrue(value)

  // data and filePath automatically cleaned up, even when an exception occurs.
}

If for whatever reason you have clean up code that needs to run but isn't in a deinit() function, you can use defer.

func qux(value: Bool) throws {
  defer {
    print("this code runs when the function exits, even when it exits by an exception")
  }

  try willOnlyThrowIfTrue(value)
}

Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit() or defer. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.

Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.

Handling exceptions is done via catch statements.

func quux(value: Bool) {
  do {
    try willOnlyThrowIfTrue(value)
  } catch {
    // handle error
  }
}

You can have multiple catch statements, each catching a different kind of exception.

  do {
    try someFunctionThatThowsDifferentExceptions()
  } catch MyErrorType.errorA {
    // handle errorA
  } catch MyErrorType.errorB {
    // handle errorB
  } catch {
    // handle other errors
  }

For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.

For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).

A concise solution:

location.search
  .slice(1)
  .split('&')
  .map(p => p.split('='))
  .reduce((obj, pair) => {
    const [key, value] = pair.map(decodeURIComponent);
    obj[key] = value;
    return obj;
  }, {});

You will have to use cookie to store the value across page refresh. You can use any one of the many javascript based cookie libraries to simplify the cookie access, like this one

If you want to support only html5 then you can think of Storage api like localStorage/sessionStorage

Ex: using localStorage and cookies library

var mode = getStoredValue('myPageMode');

function buttonClick(mode) {
    mode = mode;
    storeValue('myPageMode', mode);
}

function storeValue(key, value) {
    if (localStorage) {
        localStorage.setItem(key, value);
    } else {
        $.cookies.set(key, value);
    }
}

function getStoredValue(key) {
    if (localStorage) {
        return localStorage.getItem(key);
    } else {
        return $.cookies.get(key);
    }
}

Take me to [pookie](#pookie)

should be the correct markdown syntax to jump to the anchor point named pookie.

To insert an anchor point of that name use HTML:

<a name="pookie"></a>

Markdown doesn't seem to mind where you put the anchor point. A useful place to put it is in a header. For example:

### <a name="tith"></a>This is the Heading

works very well. (I'd demonstrate here but SO's renderer strips out the anchor.)

Note on self-closing tags and id= versus name=

An earlier version of this post suggested using <a id='tith' />, using the self-closing syntax for XHTML, and using the id attribute instead of name.

XHTML allows for any tag to be 'empty' and 'self-closed'. That is, <tag /> is short-hand for <tag></tag>, a matched pair of tags with an empty body. Most browsers will accept XHTML, but some do not. To avoid cross-browser problems, close the tag explicitly using <tag></tag>, as recommended above.

Finally, the attribute name= was deprecated in XHTML, so I originally used id=, which everyone recognises. However, HTML5 now creates a global variable in JavaScript when using id=, and this may not necessarily be what you want. So, using name= is now likely to be more friendly.

(Thanks to Slipp Douglas for explaining XHTML to me, and nailer for pointing out the HTML5 side-effect — see the comments and nailer's answer for more detail. name= appears to work everywhere, though it is deprecated in XHTML.)

If you really just want to subset each data frame by an index that exists in both data frames, you can do this with the 'match' function, like so:

data_A[match(data_B$index, data_A$index, nomatch=0),]
data_B[match(data_A$index, data_B$index, nomatch=0),]

This is, though, the same as:

data_A[data_A$index %in% data_B$index,]
data_B[data_B$index %in% data_A$index,]

Here is a demo:

# Set seed for reproducibility.
set.seed(1)

# Create two sample data sets.
data_A <- data.frame(index=sample(1:200, 90, rep=FALSE), value=runif(90))
data_B <- data.frame(index=sample(1:200, 120, rep=FALSE), value=runif(120))

# Subset data of each data frame by the index in the other.
t_A <- data_A[match(data_B$index, data_A$index, nomatch=0),]
t_B <- data_B[match(data_A$index, data_B$index, nomatch=0),]

# Make sure they match.
data.frame(t_A[order(t_A$index),], t_B[order(t_B$index),])[1:20,]

After some trial and error and observing the results (in other words, I hacked it), I got it to work.

Quotes ARE required to use a path name with spaces. The trick is there MUST be a space after the path names before the closing quote...like this...

robocopy "C:\Source Path " "C:\Destination Path " /option1 /option2...

This almost seems like a bug and certainly not very intuitive.

you just need to put this

($('#{{ form.email.id_for_label }}').attr("placeholder","Work email address"));

($('#{{ form.password1.id_for_label }}').attr("placeholder","Password"));

This is how to easily convert from an ISO string to a SQL-Server datetime:

INSERT INTO time_data (ImportateDateTime) VALUES (CAST(CONVERT(datetimeoffset,'2019-09-13 22:06:26.527000') AS datetime))

Source https://www.sqlservercurry.com/2010/04/convert-character-string-iso-date-to.html

Every object has an internal property, [[Prototype]], linking it to another object:

object [[Prototype]] ? anotherObject

In traditional javascript, the linked object is the prototype property of a function:

object [[Prototype]] ? aFunction.prototype

Some environments expose [[Prototype]] as __proto__:

anObject.__proto__ === anotherObject

You create the [[Prototype]] link when creating an object.

// (1) Object.create:
var object = Object.create(anotherObject)
// object.__proto__ = anotherObject

// (2) ES6 object initializer:
var object = { __proto__: anotherObject };
// object.__proto__ = anotherObject

// (3) Traditional JavaScript:
var object = new aFunction;
// object.__proto__ = aFunction.prototype

So these statements are equivalent:

var object = Object.create(Object.prototype);
var object = { __proto__: Object.prototype }; // ES6 only
var object = new Object;

You can't actually see the link target (Object.prototype) in a new statement; instead the target is implied by the constructor (Object).

Remember:

• Every object has a link, [[Prototype]], sometimes exposed as __proto__.
• Every function has a prototype property, initially holding an empty object.
• Objects created with new are linked to the prototype property of their constructor.
• If a function is never used as a constructor, its prototype property will go unused.
• If you don't need a constructor, use Object.create instead of new.

The <=> ("Spaceship") operator will offer combined comparison in that it will :

Return 0 if values on either side are equal
Return 1 if the value on the left is greater
Return -1 if the value on the right is greater

The rules used by the combined comparison operator are the same as the currently used comparison operators by PHP viz. <, <=, ==, >= and >. Those who are from Perl or Ruby programming background may already be familiar with this new operator proposed for PHP7.

   //Comparing Integers

    echo 1 <=> 1; //output  0
    echo 3 <=> 4; //output -1
    echo 4 <=> 3; //output  1

    //String Comparison

    echo "x" <=> "x"; //output  0
    echo "x" <=> "y"; //output -1
    echo "y" <=> "x"; //output  1

There are ALMOST only two types of JavaScript scopes:

• the scope of each var declaration is associated with the most immediately enclosing function
• if there is no enclosing function for a var declaration, it is global scope

So, any blocks other than functions do not create a new scope. That explains why for-loops overwrite outer scoped variables:

var i = 10, v = 10;
for (var i = 0; i < 5; i++) { var v = 5; }
console.log(i, v);
// output 5 5

Using functions instead:

var i = 10, v = 10;
$.each([0, 1, 2, 3, 4], function(i) { var v = 5; });
console.log(i,v);
// output 10 10

In the first example, there was no block scope, so the initially declared variables were overwritten. In the second example, there was a new scope due to the function, so the initially declared variables were SHADOWED, and not overwritten.

That's almost all you need to know in terms of JavaScript scoping, except:

• try/catch introduce new scope ONLY for the exception variable itself, other variables do not have new scope
• with-clause apparently is another exception, but using with-clause it highly discouraged (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/with)

So you can see JavaScript scoping is actually extremely simple, albeit not always intuitive. A few things to be aware of:

• var declarations are hoisted to the top of the scope. This means no matter where the var declaration happens, to the compiler it is as if the var itself happens at the top
• multiple var declarations within the same scope are combined

So this code:

var i = 1;
function abc() {
  i = 2;
  var i = 3;
}
console.log(i);     // outputs 1

is equivalent to:

var i = 1;
function abc() {
  var i;     // var declaration moved to the top of the scope
  i = 2;
  i = 3;     // the assignment stays where it is
}
console.log(i);

This may seem counter intuitive, but it makes sense from the perspective of a imperative language designer.

I was using Joni's solution and it worked fine, but this one is much shorter.

This was inspired by the atobUTF16() function of Solution #3 of Mozilla's Base64 Unicode discussion

function convertStringToUTF8ByteArray(str) {
    let binaryArray = new Uint8Array(str.length)
    Array.prototype.forEach.call(binaryArray, function (el, idx, arr) { arr[idx] = str.charCodeAt(idx) })
    return binaryArray
}

Okay I found the correct answer to this issue here

Here are the steps:

1. Filter your data.
2. Select the cells you want to add the numbering to.
3. Press F5.
4. Select Special.
5. Choose "Visible Cells Only" and press OK.

6. Now in the top row of your filtered data (just below the header) enter the following code:

   =MAX($"Your Column Letter"$1:"Your Column Letter"$"The current row for the filter - 1") + 1

   Ex:

   =MAX($A$1:A26)+1

   Which would be applied starting at cell A27.

7. Hold Ctrl and press enter.

Note this only works in a range, not in a table!

If you want to select town and total user count, you can use this query below:

SELECT Town, (SELECT Count(*) FROM User) `Count` FROM user GROUP BY Town;

You need to create new rails application first. Run

rails new mebay
cd mebay
bundle install
rails generate model ...

And try to find Rails 3 tutorial, there are a lot of changes since 2.1 Guides (http://guides.rubyonrails.org/getting_started.html) are good start point.

This is what I did on the controller

var collectionDate = '2002-04-26T09:00:00';
var date = new Date(collectionDate);
//then pushed all my data into an array $scope.rows which I then used in the directive

I ended up formatting the date to my desired pattern on the directive as follows.

var data = new google.visualization.DataTable();
                    data.addColumn('date', 'Dates');
                    data.addColumn('number', 'Upper Normal');
                    data.addColumn('number', 'Result');
                    data.addColumn('number', 'Lower Normal');
                    data.addRows(scope.rows);
                    var formatDate = new google.visualization.DateFormat({pattern: "dd/MM/yyyy"});
                    formatDate.format(data, 0);
//set options for the line chart
var options = {'hAxis': format: 'dd/MM/yyyy'}

//Instantiate and draw the chart passing in options
var chart = new google.visualization.LineChart($elm[0]);
                    chart.draw(data, options);

This gave me dates ain the format of dd/MM/yyyy (26/04/2002) on the x axis of the chart.

Add HttpModule to imports array in app.module.ts file before you use it.

import { HttpModule } from '@angular/http';_x000D_
_x000D_
@NgModule({_x000D_
  declarations: [_x000D_
    AppComponent,_x000D_
    CarsComponent_x000D_
  ],_x000D_
  imports: [_x000D_
    BrowserModule,_x000D_
 HttpModule  _x000D_
  ],_x000D_
  providers: [],_x000D_
  bootstrap: [AppComponent]_x000D_
})_x000D_
export class AppModule { }

For a google maps integration I was looking for a way to detect when a div has changed in size. Since google maps always require proper dimensions e.g. width and height in order to render properly.

The solution I came up with is a delegation of an event, in my case a tab click. This could be a window resize of course, the idea remains the same:

if (parent.is(':visible')) {
    w = parent.outerWidth(false);
    h = w * mapRatio /*9/16*/;
    this.map.css({ width: w, height: h });
} else {
    this.map.closest('.tab').one('click', function() {
        this.activate();
    }.bind(this));
}

this.map in this case is my map div. Since my parent is invisible on load, the computed width and height are 0 or don't match. By using .bind(this) I can delegate the script execution (this.activate) to an event (click).

Now I'm confident the same applies for resize events.

$(window).one('resize', function() {
    this.div.css({ /*whatever*/ });
}.bind(this));

Hope it helps anyone!

Here is a plunker showing how you can use it with the ngClass directive.

I'm demonstrating with divs instead of imgs though.

Template:

<ul>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 1}" (click)="setSelected(1)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 2}" (click)="setSelected(2)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 3}" (click)="setSelected(3)"> </div></li>
</ul>

TS:

export class App {
  selectedIndex = -1;

  setSelected(id: number) {
    this.selectedIndex = id;
  }
}

Add XAttribute in the constructor of the XElement, like

new XElement("Conn", new XAttribute("Server", comboBox1.Text));

You can also add multiple attributes or elements via the constructor

new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));

or you can use the Add-Method of the XElement to add attributes

XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);

Here is a working solution:

Instead of setting the spinner's OnClickListener, we are setting OnTouchListener and OnKeyListener.

spinner.setOnTouchListener(Spinner_OnTouch);
spinner.setOnKeyListener(Spinner_OnKey);

and the listeners:

private View.OnTouchListener Spinner_OnTouch = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatYouWantHere();
        }
        return true;
    }
};
private static View.OnKeyListener Spinner_OnKey = new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
            doWhatYouWantHere();
            return true;
        } else {
            return false;
        }
    }
};

I use mailutils and the confusing part is that in order to attach a file you need to use the capital A parameter. below is an example.

echo 'here you put the message body' | mail -A syslogs.tar.gz [email protected]

If you want to know if your mail command is from mailutils just run "mail -V".

The necessary variable is inventory_hostname.

- name: Install this only for local dev machine
  pip: name=pyramid
  when: inventory_hostname == "local"

It is somewhat hidden in the documentation at the bottom of this section.

Just a note for @"John Sansom" answer,

If the foreign key dependencies are sought, I think that the PT Where clause should be:

i1.CONSTRAINT_TYPE = 'FOREIGN KEY'  -- instead of 'PRIMARY KEY'

and its the ON condition:

ON PT.TABLE_NAME = FK.TABLE_NAME – instead of PK.TABLE_NAME

As commonly is used the primary key of the foreign table, I think this issue has not been noticed before.

Remove conn.commit from Register.java

In your jsp change action to :<form name="registrationform" action="Register" method="post">

So there are several ways to get a resource from a jar and each has slightly different syntax where the path needs to be specified differently.

The best explanation I have seen is this article from InfoWorld. I'll summarize here, but if you want to know more you should check out the article.

Methods

1. ClassLoader.getResourceAsStream().

Format: "/"-separated names; no leading "/" (all names are absolute).

Example: this.getClass().getClassLoader().getResourceAsStream("some/pkg/resource.properties");

2. Class.getResourceAsStream()

Format: "/"-separated names; leading "/" indicates absolute names; all other names are relative to the class's package

Example: this.getClass().getResourceAsStream("/some/pkg/resource.properties");

Updated Sep 2020: Changed article link. Original article was from Javaworld, it is now hosted on InfoWorld (and has many more ads)

Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.

def Reset():
    cmb.set("")

here, cmb is a variable in which you have assigned the Combobox. Now call that function in a button such as,

btn2 = ttk.Button(root, text="Reset",command=Reset)

Change the group permission for the folder

sudo chown -R w3cert /home/w3cert/.composer/cache/repo/https---packagist.org

and the Files folder too

sudo chown -R w3cert /home/w3cert/.composer/cache/files/

I'm assuming w3cert is your username, if not change the 4th parameter to your username.

If the problem still persists try

sudo chown -R w3cert /home/w3cert/.composer

Now, there is a chance that you won't be able to create your app directory, if that happens do the same for your html folder or the folder you are trying to create your laravel project in.

Hope this helps.

Found a very easy way to do this.

Open http://phpfiddle.org/

Paste following php script in box. In php script set API_ACCESS_KEY, set device ids separated by coma.

Press F9 or click Run.

Have fun ;)

<?php


// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );


$registrationIds = array("YOUR DEVICE IDS WILL GO HERE" );

// prep the bundle
$msg = array
(
    'message'       => 'here is a message. message',
    'title'         => 'This is a title. title',
    'subtitle'      => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 1
);

$fields = array
(
    'registration_ids'  => $registrationIds,
    'data'              => $msg
);

$headers = array

Some response codes:

Following is the description of some response codes you may receive from server.

{ "message_id": "XXXX" } - success
{ "message_id": "XXXX", "registration_id": "XXXX" } - success, device registration id has been changed mainly due to app re-install
{ "error": "Unavailable" } - Server not available, resend the message
{ "error": "InvalidRegistration" } - Invalid device registration Id 
{ "error": "NotRegistered"} - Application was uninstalled from the device

The call

e.extractAll("th")

for a regular method extractAll() is indeed equivalent to

Extractor.extractAll(e, "th")

These two calls are treated the same in all regards, including the error messages you get.

If you don't need to pass the instance to a method, you can use a staticmethod:

@staticmethod
def extractAll(tag):
    ...

which can be called as e.extractAll("th"). But I wonder why this is a method on a class at all if you don't need to access any instance.

I'll try and explain it as simple as possible. So there is no guarantee of the accuracy of the actual terms.

Session is where to initiate the connectivity to AWS services. E.g. following is default session that uses the default credential profile(e.g. ~/.aws/credentials, or assume your EC2 using IAM instance profile )

sqs = boto3.client('sqs')
s3 = boto3.resource('s3')

Because default session is limit to the profile or instance profile used, sometimes you need to use the custom session to override the default session configuration (e.g. region_name, endpoint_url, etc. ) e.g.

# custom resource session must use boto3.Session to do the override
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource('s3')
video_s3 = my_east_session.resource('s3')

# you have two choices of create custom client session. 
backup_s3c = my_west_session.client('s3')
video_s3c = boto3.client("s3", region_name = 'us-east-1')

Resource : This is the high-level service class recommended to be used. This allows you to tied particular AWS resources and passes it along, so you just use this abstraction than worry which target services are pointed to. As you notice from the session part, if you have a custom session, you just pass this abstract object than worrying about all custom regions,etc to pass along. Following is a complicated example E.g.

import boto3 
my_west_session = boto3.Session(region_name = 'us-west-2')
my_east_session = boto3.Session(region_name = 'us-east-1')
backup_s3 = my_west_session.resource("s3")
video_s3 = my_east_session.resource("s3")
backup_bucket = backup_s3.Bucket('backupbucket') 
video_bucket = video_s3.Bucket('videobucket')

# just pass the instantiated bucket object
def list_bucket_contents(bucket):
   for object in bucket.objects.all():
      print(object.key)

list_bucket_contents(backup_bucket)
list_bucket_contents(video_bucket)

Client is a low level class object. For each client call, you need to explicitly specify the targeting resources, the designated service target name must be pass long. You will lose the abstraction ability.

For example, if you only deal with the default session, this looks similar to boto3.resource.

import boto3 
s3 = boto3.client('s3')

def list_bucket_contents(bucket_name):
   for object in s3.list_objects_v2(Bucket=bucket_name) :
      print(object.key)

list_bucket_contents('Mybucket') 

However, if you want to list objects from a bucket in different regions, you need to specify the explicit bucket parameter required for the client.

import boto3 
backup_s3 = my_west_session.client('s3',region_name = 'us-west-2')
video_s3 = my_east_session.client('s3',region_name = 'us-east-1')

# you must pass boto3.Session.client and the bucket name 
def list_bucket_contents(s3session, bucket_name):
   response = s3session.list_objects_v2(Bucket=bucket_name)
   if 'Contents' in response:
     for obj in response['Contents']:
        print(obj['key'])

list_bucket_contents(backup_s3, 'backupbucket')
list_bucket_contents(video_s3 , 'videobucket') 

Before applying WORKDIR. Here the WORKDIR is at the wrong place and is not used wisely.

FROM microsoft/aspnetcore:2
COPY --from=build-env /publish /publish
WORKDIR /publish
ENTRYPOINT ["dotnet", "/publish/api.dll"]

We corrected the above code to put WORKDIR at the right location and optimised the following statements by removing /Publish

FROM microsoft/aspnetcore:2
WORKDIR /publish
COPY --from=build-env /publish .
ENTRYPOINT ["dotnet", "api.dll"]

So it acts like a cd and sets the tone for the upcoming statements.

Try this

#include <iostream>
#include <algorithm>


int main () {
  int myArray[] = { 3 ,6 ,8, 33 };
  int x = 8;

  if (std::any_of(std::begin(myArray), std::end(myArray), [=](int n){return n == x;}))   {
      std::cout << "found match/" << std::endl;
  }

  return 0;

}

The SQLite command line utility has a .schema TABLENAME command that shows you the create statements.

If you are using windows, remove comment on these lines and set them as:

Line 227 : ServerName 127.0.0.1:80 
Line 235 : AllowOverride all 
Line 236 : Require all granted

Worked for me!

This is called the "shape" in NumPy, and can be requested via the .shape attribute:

>>> a = zeros((2, 5))
>>> a.shape
(2, 5)

If you prefer a function, you could also use numpy.shape(a).

Use this to execute *.sql files when the PostgreSQL server is located in a difference place:

psql -h localhost -d userstoreis -U admin -p 5432 -a -q -f /home/jobs/Desktop/resources/postgresql.sql

-h PostgreSQL server IP address
-d database name
-U user name
-p port which PostgreSQL server is listening on
-f path to SQL script
-a all echo
-q quiet

Then you are prompted to enter the password of the user.

In real life you wish to simulate a signal with white noise. You should add to your signal random points that have Normal Gaussian distribution. If we speak about a device that have sensitivity given in unit/SQRT(Hz) then you need to devise standard deviation of your points from it. Here I give function "white_noise" that does this for you, an the rest of a code is demonstration and check if it does what it should.

%matplotlib inline

def white_noise(rho, sr, n, mu=0):
    sigma = rho * np.sqrt(sr/2)
    noise = np.random.normal(mu, sigma, n)
    return noise

rho = 1 
sr = 1000
n = 1000
period = n/sr
time = np.linspace(0, period, n)

BTW if the distribution of values indicates that an index scan will not be the worth (for example if all the values are in 2012), the optimiser could still choose a full table scan. YMMV. Explain is your friend.

It should not effect the load time much since you are overriding parts of the base stylesheet.

Here are some best practices I personally follow:

1. Always load custom CSS after the base CSS file (not responsive).
2. Avoid using !important if possible. That can override some important styles from the base CSS files.
3. Always load bootstrap-responsive.css after custom.css if you don't want to lose media queries. - MUST FOLLOW
4. Prefer modifying required properties (not all).

def get_client_ip(request):
    x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
    if x_forwarded_for:
        ip = x_forwarded_for.split(',')[0]
    else:
        ip = request.META.get('REMOTE_ADDR')
    return ip

Make sure you have reverse proxy (if any) configured correctly (e.g. mod_rpaf installed for Apache).

Note: the above uses the first item in X-Forwarded-For, but you might want to use the last item (e.g., in the case of Heroku: Get client's real IP address on Heroku)

And then just pass the request as argument to it;

get_client_ip(request)

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

Think of it as the VM that has siloed the process the app or service is running in. The siloed environment has access to a bunch of underlying system information and certain permitted resources. You need that context to get at those services.

my OS is ubuntu, XAMPP installed in /opt/lampp, and I found php.ini in /opt/lampp/etc/php.ini

In addition to what @inkedmn has pointed out, a static member is at the class level. Therefore, the said member is loaded into memory by the JVM once for that class (when the class is loaded). That is, there aren't n instances of a static member loaded for n instances of the class to which it belongs.

Try this

select count(*) from table where cast(col as double) is null;

You should be referencing Selected not ids.Contains as the last line.

I just realized this is a formatting issue, from the OP. Regardless you should be referencing the value in Selected. I recommend adding some Console.WriteLine calls to see exactly what is being printed out on each line and also what each value is.

After your update: ids is an empty list, how is this not throwing a NullReferenceException? As it was never initialized in that code block

Fastest that I found here for PHP 7.2 on Ububntu 18.04

preg_replace('/^(\w+\\\)*/', '', static::class)

First check the logs why the container failed. Because your restart policy might bring your container back to running status. Better to fix the issue, Then probably you can build a new image with/without fix. Later execute below command

REVERSIBLE Method to Discard All Changes:

I found this question after after making a merge and forgetting to checkout develop immediately afterwards. You guessed it: I started modifying a few files directly on master. D'Oh! As my situation is hardly unique (we've all done it, haven't we ;->), I'll offer a reversible way I used to discard all changes to get master looking like develop again.

After doing a git diff to see what files were modified and assess the scope of my error, I executed:

git stash
git stash clear

After first stashing all the changes, they were next cleared. All the changes made to the files in error to master were gone and parity restored.

Let's say I now wanted to restore those changes. I can do this. First step is to find the hash of the stash I just cleared/dropped:

git fsck --no-reflog | awk '/dangling commit/ {print $3}'

After learning the hash, I successfully restored the uncommitted changes with:

git stash apply hash-of-cleared-stash

I didn't really want to restore those changes, just wanted to validate I could get them back, so I cleared them again.

Another option is to apply the stash to a different branch, rather than wipe the changes. So in terms of clearing changes made from working on the wrong branch, stash gives you a lot of flexibility to recover from your boo-boo.

Anyhoo, if you want a reversible means of clearing changes to a branch, the foregoing is a less dangerous way in this use-case.

Wordpress 4.2 introduced support for "utf8mb4" character encoding for security reasons, but only MySQL 5.5.3 and greater support it. The way the installer (and updater) handles this is that it checks your MySQL version and your database will be upgraded to utfmb4 only if it's supported.

This sounds great in theory but the problem (as you've discovered) is when you are migrating databases from a MySQL server that supports utf8mb4 to one that doesn't. While the other way around should work, it's basically a one-way operation.

As pointed out by Evster you might have success using PHPMYAdmin's "Export" feature. Use "Export Method: Custom" and for the "Database system or older MySQL server to maximize output compatibility with:" dropdown select "MYSQL 40".

For a command line export using mysqldump. Have a look at the flag:

$ mysqldump --compatible=mysql4

Note: If there are any 4-byte characters in the database they will be corrupted.

Lastly, for anyone using the popular WP Migrate DB PRO plugin, a user in this Wordpress.org thread reports that the migration is always handled properly but I wasn't able to find anything official.

The WP Migrate DB plugin translates the database from one collation to the other when it moves 4.2 sites between hosts with pre- or post-5.5.3 MySQL

At this time, there doesn't appear to be a way to opt out of the database update. So if you are using a workflow where you are migrating a site from a server or localhost with MySQL > 5.5.3 to one that uses an older MySQL version you might be out of luck.

>>> stuff = "Big and small"
>>> stuff.replace(" and ","/")

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

Just a a bit modifications on reading string from a file method for more performance

private String readFromFile(Context context, String fileName) {
    if (context == null) {
        return null;
    }

    String ret = "";

    try {
        InputStream inputStream = context.openFileInput(fileName);

        if ( inputStream != null ) {
            InputStreamReader inputStreamReader = new InputStreamReader(inputStream);               

            int size = inputStream.available();
            char[] buffer = new char[size];

            inputStreamReader.read(buffer);

            inputStream.close();
            ret = new String(buffer);
        }
    }catch (Exception e) {
        e.printStackTrace();
    }

    return ret;
}

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

import * as utils from './utils.js'; 

If you do the above, you will be able to use functions in utils.js as

As far as I'm aware, styling a parent element based on the child element is not an available feature of CSS. You'll likely need scripting for this.

It'd be wonderful if you could do something like div[div.a] or div:containing[div.a] as you said, but this isn't possible.

You may want to consider looking at jQuery. Its selectors work very well with 'containing' types. You can select the div, based on its child contents and then apply a CSS class to the parent all in one line.

If you use jQuery, something along the lines of this would may work (untested but the theory is there):

$('div:has(div.a)').css('border', '1px solid red');

or

$('div:has(div.a)').addClass('redBorder');

combined with a CSS class:

.redBorder
{
    border: 1px solid red;
}

Here's the documentation for the jQuery "has" selector.

You should make a habit of looking at the documentation for stuff like this. It's very useful and will improve your skills very quickly. Here's the relevant bit when you do git help diff

   git diff [options] [--no-index] [--] <path> <path>

The two <path>s are what you need to change to the directories in question.

If you will add UIUserInterfaceStyle key to the plist file, possibly Apple will reject release build as mentioned here: https://stackoverflow.com/a/56546554/7524146 Anyway it's annoying to explicitly tell each ViewController self.overrideUserInterfaceStyle = .light. But you can use this peace of code once for your root window object:

if #available(iOS 13.0, *) {
    if window.responds(to: Selector(("overrideUserInterfaceStyle"))) {
        window.setValue(UIUserInterfaceStyle.light.rawValue, forKey: "overrideUserInterfaceStyle")
    }
}

Just notice you can't do this inside application(application: didFinishLaunchingWithOptions:) because for this selector will not respond true at that early stage. But you can do it later on. It's super easy if you are using custom AppPresenter or AppRouter class in your app instead of starting UI in the AppDelegate automatically.
