if you can write a batch file that does not need to be interactive, try running that batch file as a service, to do what needs to be done.

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

try this one :),

Get-LocalGroup | %{ $groups = "$(Get-LocalGroupMember -Group $_.Name | %{ $_.Name } | Out-String)"; Write-Output "$($_.Name)>`r`n$($groups)`r`n" }

Did you try passwd -d root? Most likely, this will do what you want.

You can also manually edit /etc/shadow: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to

root:$X$SK5xfLB1ZW:0:0...

There, delete the second field (everything between the first and second colon):

root::0:0...

Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)

root:*:0:0...

Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd, and use mkpasswd to create the second field for the /etc/shadow.)

select * 
from ROLE_TAB_PRIVS 
where role in (
    select granted_role
    from dba_role_privs 
    where granted_role in ('ROLE1','ROLE2')
)

I use the SubInACL utility for this. For example, if I wanted to give the user job on the computer VMX001 the ability to start and stop the World Wide Web Publishing Service (also know as w3svc), I would issue the following command as an Administrator:

subinacl.exe /service w3svc /grant=VMX001\job=PTO

The permissions you can grant are defined as follows (list taken from here):

F : Full Control
R : Generic Read
W : Generic Write
X : Generic eXecute
L : Read controL
Q : Query Service Configuration
S : Query Service Status
E : Enumerate Dependent Services
C : Service Change Configuration
T : Start Service
O : Stop Service
P : Pause/Continue Service
I : Interrogate Service 
U : Service User-Defined Control Commands

So, by specifying PTO, I am entitling the job user to Pause/Continue, Start, and Stop the w3svc service.

The mysql_* functions are deprecated and unsafe. The code in your question in vulnerable to injection attacks. It is highly recommended that you use the PDO extension instead, like so:

session_start();

$query = "SELECT 'id' FROM Users WHERE username = :name LIMIT 1";
$statement = $PDO->prepare($query);
$params = array(
    'name' => $_GET["username"]
);
$statement->execute($params);
$user_data = $statement->fetch();

$_SESSION['myid'] = $user_data['id'];

Where $PDO is your PDO object variable. See https://www.php.net/pdo_mysql for more information about PHP and PDO.

For extra help:

Here's a jumpstart on how to connect to your database using PDO:

$database_username = "YOUR_USERNAME";
$database_password = "YOUR_PASSWORD";
$database_info = "mysql:host=localhost;dbname=YOUR_DATABASE_NAME";
try
{
    $PDO = new PDO($database_info, $database_username, $database_password);
}
catch(PDOException $e)
{
    // Handle error here
}

You don't need to delete objects in java. When there is no reference to an object, it will be collected by the garbage collector automatically.

Apparently xerces:xml-apis:1.4.01 is no longer in maven central, which is however what xerces:xercesImpl:2.11.0 references.

This works for me:

<dependency>
  <groupId>xerces</groupId>
  <artifactId>xercesImpl</artifactId>
  <version>2.11.0</version>
  <exclusions>
    <exclusion>
      <groupId>xerces</groupId>
      <artifactId>xml-apis</artifactId>

You can use parseInt with try and catch block

try
{
    int myVal= Integer.parseInt(mTextView.getText().toString());
}
catch (NumberFormatException e)
{
    // handle the exception
    int myVal=0;
}

Or you can create your own tryParse method :

public Integer tryParse(Object obj) {
    Integer retVal;
    try {
        retVal = Integer.parseInt((String) obj);
    } catch (NumberFormatException nfe) {
        retVal = 0; // or null if that is your preference
    }
    return retVal;
}

and use it in your code like:

int myVal= tryParse(mTextView.getText().toString());

Note: The following code without try/catch will throw an exception

int myVal= new Integer(mTextView.getText().toString()).intValue();

Or

int myVal= Integer.decode(mTextView.getText().toString()).intValue();

The above solutions must work. However you can try this one:

OnClientClick="return SomeMethod();return false;"

and remove return statement from the method.

There seems to be issues where Remove-Item -Force -Recurse can intermittently fail on Windows because the underlying filesystem is asynchronous. This answer seems to address it. The user has also been actively involved with the Powershell team on GitHub.

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

What character encoding are you using? Some character sets (like UTF-16, et cetera) use more than one byte per character.

Use following to configure select2

    $('#selectelementid').select2({
        placeholder: "Please select an agent",
        allowClear: true // This is for clear get the clear button if wanted 
    });

And to clear select input programmatically

    $("#selectelementid").val("").trigger("change");
    $("#selectelementid").trigger("change");

This seems ridiculous and far fetched but you could always use Windows (or whatever OS you prefer) to manage the sound for you!

import os
os.system("start C:/thepathyouwant/file")

Simple, no extensions, somewhat slow and junky, but working.

Safe and simple:

[]byte("Here is a string....")

The solution for the error is to add this line at the top of the code:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

unsigned char c;

for( int i = 7; i >= 0; i-- ) {
    printf( "%d", ( c >> i ) & 1 ? 1 : 0 );
}

printf("\n");

Explanation:

With every iteration, the most significant bit is being read from the byte by shifting it and binary comparing with 1.

For example, let's assume that input value is 128, what binary translates to 1000 0000. Shifting it by 7 will give 0000 0001, so it concludes that the most significant bit was 1. 0000 0001 & 1 = 1. That's the first bit to print in the console. Next iterations will result in 0 ... 0.

I needed the bar labels too, note that my y-axis is having a zoomed view using limits on y axis. The default calculations for putting the labels on top of the bar still works using height (use_global_coordinate=False in the example). But I wanted to show that the labels can be put in the bottom of the graph too in zoomed view using global coordinates in matplotlib 3.0.2. Hope it help someone.

def autolabel(rects,data):
"""
Attach a text label above each bar displaying its height
"""
c = 0
initial = 0.091
offset = 0.205
use_global_coordinate = True

if use_global_coordinate:
    for i in data:        
        ax.text(initial+offset*c, 0.05, str(i), horizontalalignment='center',
                verticalalignment='center', transform=ax.transAxes,fontsize=8)
        c=c+1
else:
    for rect,i in zip(rects,data):
        height = rect.get_height()
        ax.text(rect.get_x() + rect.get_width()/2., height,str(i),ha='center', va='bottom')

Basically what the transpose function does is to swap the shape and strides of the array:

>>> a = np.ones((1,2,3))

>>> a.shape
(1, 2, 3)

>>> a.T.shape
(3, 2, 1)

>>> a.strides
(48, 24, 8)

>>> a.T.strides
(8, 24, 48)

In case of 1D numpy array (rank-1 array) the shape and strides are 1-element tuples and cannot be swapped, and the transpose of such an 1D array returns it unchanged. Instead, you can transpose a "row-vector" (numpy array of shape (1, n)) into a "column-vector" (numpy array of shape (n, 1)). To achieve this you have to first convert your 1D numpy array into row-vector and then swap the shape and strides (transpose it). Below is a function that does it:

from numpy.lib.stride_tricks import as_strided

def transpose(a):
    a = np.atleast_2d(a)
    return as_strided(a, shape=a.shape[::-1], strides=a.strides[::-1])

Example:

>>> a = np.arange(3)
>>> a
array([0, 1, 2])

>>> transpose(a)
array([[0],
       [1],
       [2]])

>>> a = np.arange(1, 7).reshape(2,3)
>>> a     
array([[1, 2, 3],
       [4, 5, 6]])

>>> transpose(a)
array([[1, 4],
       [2, 5],
       [3, 6]])

Of course you don't have to do it this way since you have a 1D array and you can directly reshape it into (n, 1) array by a.reshape((-1, 1)) or a[:, None]. I just wanted to demonstrate how transposing an array works.

Found a solution. This problem happens, when you import a project.

The solution is simple

1. Right click -> Properties
2. Project Facets -> Check Dyanmic Web Module and Java Version
3. Apply Setting.

Now you should see the web app libraries showing your jars added.

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

Internet Control Message Protocol

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

ICMP is built on top of a bunch of other protocols, so in that sense your TA is correct. However, ping itself is ICMP.

To make it clear, in addition to @SLaks' answer, that meant you need to change this line :

List<RootObject> datalist = JsonConvert.DeserializeObject<List<RootObject>>(jsonstring);

to something like this :

RootObject datalist = JsonConvert.DeserializeObject<RootObject>(jsonstring);

The problem is that your method does NOT return a list of TestA if it contains a TestB, so what if it was correctly typed? Then this cast:

class TestA{};
class TestB extends TestA{};
List<? extends TestA> listA;
List<TestB> listB = (List<TestB>) listA;

works about as well as you could hope for (Eclipse warns you of an unchecked cast which is exactly what you are doing, so meh). So can you use this to solve your problem? Actually you can because of this:

List<TestA> badlist = null; // Actually contains TestBs, as specified
List<? extends TestA> talist = badlist;  // Umm, works
List<TextB> tblist = (List<TestB>)talist; // TADA!

Exactly what you asked for, right? or to be really exact:

List<TestB> tblist = (List<TestB>)(List<? extends TestA>) badlist;

seems to compile just fine for me.

It sounds like you are on the right track with your directory structure. When you compile the dependent code, specify the -classpath argument of javac. Use the parent directory of the com directory, where com, in turn, contains company/thing/YourClass.class

So, when you do this:

javac -classpath <parent> client.java

The <parent> should be referring to the parent of com. If you are in com, it would be ../.

You can use Loadsh library to do this more efficiently, like:

if you have an array named "pets", for example:

var pets = ['dog', undefined, 'cat', null];

console.log(_.isEmpty(pets[1])); // true
console.log(_.isEmpty(pets[3])); // true
console.log(_.isEmpty(pets[4])); // false

_.map( pets, (pet, index) => { console.log(index + ': ' + _.isEmpty(pet) ) });

To check all array values for null or undefined values:

var pets = ['dog', undefined, 'cat', null];_x000D_
_x000D_
console.log(_.isEmpty(pets[1])); // true_x000D_
console.log(_.isEmpty(pets[3])); // true_x000D_
console.log(_.isEmpty(pets[4])); // false_x000D_
_x000D_
_.map( pets, (pet, index) => { console.log(index + ': ' + _.isEmpty(pet) ) });

In version 5.6 at least, the Management tab in MySQL Workbench shows that it's in a hidden folder called ProgramData in the C:\ drive. My default data directory is

C:\ProgramData\MySQL\MySQL Server 5.6\data

. Each database has a folder and each table has a file here.

An alternative that always exists for learning purpose is to build your custom collector through Collector.of() though toMap() JDK collector here is succinct (+1 here) .

Map<String,Integer> newMap = givenMap.
                entrySet().
                stream().collect(Collector.of
               ( ()-> new HashMap<String,Integer>(),
                       (mutableMap,entryItem)-> mutableMap.put(entryItem.getKey(),Integer.parseInt(entryItem.getValue())),
                       (map1,map2)->{ map1.putAll(map2); return map1;}
               ));

This is a very low-level exception, which is ORA-17410.

It may happen for several reasons:

1. A temporary problem with networking.

2. Wrong JDBC driver version.

3. Some issues with a special data structure (on database side).

4. Database bug.

In my case, it was a bug we hit on the database, which needs to be patched.

Armin's answer is so useful, thank you. #2 is what's most important to know when trying to set up unload events that work in most browsers: you cannot alert() or confirm(), but returning a string will generate a confirm modal.

But I found that even with just returning a string, I had some cross-browser issues specific to Mootools (using version 1.4.5 in this instance). This Mootools-specific implementation worked great in Firefox, but did not result in a confirm popup in Chrome or Safari:

window.addEvent("beforeunload", function() {
    return "Are you sure you want to leave this page?";
});

So in order to get my onbeforeonload event to work across browsers, I had to use the JavaScript native call:

window.onbeforeunload = function() {
    return "Are you sure you want to leave this page?";
}

Not sure why this is the case, or if it's been fixed in later versions of Mootools.

It's simple.

Parent parent = new Child();

In this case the type of the object is Parent. Ant Parent has only one properties. It's name.

Child child = new Child();

And in this case the type of the object is Child. Ant Child has two properties. They're name and salary.

The fact is that there's no need to initialize non-final field immediately at the declaration. Usually this’s done at run-time because often you cannot know exactly what exactly implementation will you need. For example imagine that you have a class hierarchy with class Transport at the head. And three subclasses: Car, Helicopter and Boat. And there's another class Tour which has field Transport. That is:

class Tour {
   Transport transport;
}  

As long as an user hasn't booked a trip and hasn't chosen a particular type of transport you can't initialize this field. It's first.

Second, assume that all of these classes must have a method go() but with a different implementation. You can define a basic implementation by default in the superclass Transport and own unique implementations in each subclass. With this initialization Transport tran; tran = new Car(); you can call the method tran.go() and get result without worrying about specific implementation. It’ll call overrided method from particular subclass.

Moreover you can use instance of subclass everywhere where instance of superclass is used. For example you want provide opportunity to rent your transport. If you don't use polymorphism, you have to write a lot of methods for each case: rentCar(Car car), rentBoat(Boat boat) and so forth. At the same time polymorphism allows you to create one universal method rent(Transport transport). You can pass in it object of any subclass of Transport. In addition, if over time your logic will increase up and you'll need to create another class in the hierarchy? When using polymorphism you don't need to change anything. Just extend class Transport and pass your new class into the method:

public class Airplane extends Transport {
    //implementation
}

and rent(new Airplane()). And new Airplane().go() in second case.

Ok. Everyone has given answers with tricks but i think the right way to achieve this is by

Connecting the following action to the "Did End On Exit" event in Interface Builder. (right-click the TextField and cntrl-drag from 'Did end on exit' to the following method.

-(IBAction)hideTheKeyboard:(id)sender
{
    [self.view endEditing:TRUE];
}

As Obama says "Yes We Can". Here is the link to it. developers.google.com/#jquery

You need to use

But i would not recommend you hosting from cdn for the following reasons

1. Although your chance of hit rate is good in case of Google CDN compared to others but it's still abysmally low.(any cdn not just google).
2. Loading via cdn you will have 3 requests one for jQuery.js, one for jQueryUI.js and one for your code. You might as will compress it on your local and load it as one single resource.

Just delete your .metadata folder in your workspace and start eclipse....:)

This might help:

If the adb connection is ever lost:

Make sure that your host is still connected to the same Wi-Fi network your Android device is. Reconnect by executing the "adb connect IP" step. (IP is obviously different when you change location.) Or if that doesn't work, reset your adb host: adb kill-server and then start over from the beginning.

If you encounter a failed deployment to an Andorid device or emulator with the error "Failure [INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES]" in the Output Window, simply delete the existing app on the device or emulator and redeploy. Debug builds will use a debug certificate while Release builds will use your configured certificate. This error is simply letting you know that the certificate of the app installed on the device is different than the one you are attempting to install. In non-development (app store) scenarios, this can be indicator of a corrupted or otherwise modified app not safe to install on the device.

I have used sub-query and it worked great!

SELECT *,(SELECT count(*) FROM $this->tbl_news WHERE
$this->tbl_news.cat_id=$this->tbl_categories.cat_id) as total_news FROM
$this->tbl_categories

I tried your code and got a top rounded corner button. I gave the colors as @ffffff and stroke I gave #C0C0C0.

try

1. Giving android : bottomLeftRadius="0.1dp" instead of 0. if its not working
2. Check in what drawable and the emulator's resolution. I created a drawable folder under res and using it. (hdpi, mdpi ldpi) the folder you have this XML. this is my output.

Yes, there is better. Check the stat or the fstat function

System.Windows.MessageBox.Show("Hello world"); //WPF
System.Windows.Forms.MessageBox.Show("Hello world"); //WinForms

try like this

string s = "2.4200";

s = s.TrimStart('0').TrimEnd('0', '.');

and then convert that to float

Is there an universal way to find the location of an external SD card?

By universal way, if you mean official way; yes there is one.

In API level 19 i.e. in Android version 4.4 Kitkat, they have added File[] getExternalFilesDirs (String type) in Context Class that allows apps to store data/files in micro SD cards.

Android 4.4 is the first release of the platform that has actually allowed apps to use SD cards for storage. Any access to SD cards before API level 19 was through private, unsupported APIs.

getExternalFilesDirs(String type) returns absolute paths to application-specific directories on all shared/external storage devices. It means, it will return paths to both internal and external memory. Generally, second returned path would be the storage path for microSD card (if any).

But note that,

Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using getExternalStorageState(File).

There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.

Forever takes command line options for output:

-l  LOGFILE      Logs the forever output to LOGFILE
-o  OUTFILE      Logs stdout from child script to OUTFILE
-e  ERRFILE      Logs stderr from child script to ERRFILE

For example:

forever start -o out.log -e err.log my-script.js

See here for more info

As per my understanding, When ever we execute print statements output will be written to buffer. And we will see the output on screen when buffer get flushed(cleared). By default buffer will be flushed when program exits. BUT WE CAN ALSO FLUSH THE BUFFER MANUALLY by using "sys.stdout.flush()" statement in the program. In the below code buffer will be flushed when value of i reaches 5.

You can understand by executing the below code.

chiru@online:~$ cat flush.py

import time
import sys

for i in range(10):
    print i
    if i == 5:
        print "Flushing buffer"
        sys.stdout.flush()
    time.sleep(1)

for i in range(10):
    print i,
    if i == 5:
        print "Flushing buffer"
        sys.stdout.flush()

chiru@online:~$ python flush.py 
0 1 2 3 4 5 Flushing buffer
6 7 8 9 0 1 2 3 4 5 Flushing buffer
6 7 8 9

On centos 7, I just do

sudo yum install java-sdk

I assume you have most common repo already. Centos just finds the correct SDK with the -devel sufix.

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

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

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

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

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

The best solution for me was to both

• use the python binary in the venv bin/ directory
• set the python path to include the venv modules directory.

man python mentions modifying the path in shell at $PYTHONPATH or in python with sys.path

Other answers mention ideas for doing this using the shell. From python, adding the following lines to my script allows me to successfully run it directly from cron.

import sys
sys.path.insert(0,'/path/to/venv/lib/python3.3/site-packages');

ocw.mit.edu is a great resource that has helped me a bunch. randi is the best option, but if your into number fun try using the floor function with rand to get what you want.

I drew a number line and came up with

floor(rand*8) + 13

If you want to allow the user to browse for a file, you need to have an input type="file" The closest you could get to your requirement would be to place the input type="file" on the page and hide it. Then, trigger the click event of the input when the button is clicked:

#myFileInput {
    display:none;
}

<input type="file" id="myFileInput" />
<input type="button"
       onclick="document.getElementById('myFileInput').click()" 
       value="Select a File" />

Here's a working fiddle.

Note: I would not recommend this approach. The input type="file" is the mechanism that users are accustomed to using for uploading a file.

Another way of doing this is using border-image in combination with a linear-gradient.

div {_x000D_
  width: 100px;_x000D_
  height: 75px;_x000D_
  background-color: green;_x000D_
  background-clip: content-box; /* so that the background color is not below the border */_x000D_
  _x000D_
  border-left: 5px solid black;_x000D_
  border-image: linear-gradient(to top, #000 50%, rgba(0,0,0,0) 50%); /* to top - at 50% transparent */_x000D_
  border-image-slice: 1;_x000D_
}

<div></div>

For a better support also add vendor prefixes.

First Method

 View someView = findViewById(R.id.randomViewInMainLayout);// get Any child View

  // Find the root view
  View root = someView.getRootView()

  // Set the color
  root.setBackgroundColor(getResources().getColor(android.R.color.red));

Second Method

Add this single line after setContentView(...);

getWindow().getDecorView().setBackgroundColor(Color.WHITE);

Third Method

set background color to the rootView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF"
android:id="@+id/rootView"
</LinearLayout>

Important Thing

rootView.setBackgroundColor(0xFF00FF00); //after 0x the other four pairs are alpha,red,green,blue color. 

In Java its Webelement.getText() . Not sure about python.

The behavior of tintColor for bars has changed on iOS 7.0. It no longer affects the bar's background and behaves as described for the tintColor property added to UIView. To tint the bar's background, please use -barTintColor.

navController.navigationBar.barTintColor = [UIColor navigationColor];

This actually does make a (potentially) huge difference to the optimizer in the compiler. Compilers have actually had this feature for years via the empty throw() statement after a function definition, as well as propriety extensions. I can assure you that modern compilers do take advantage of this knowledge to generate better code.

Almost every optimization in the compiler uses something called a "flow graph" of a function to reason about what is legal. A flow graph consists of what are generally called "blocks" of the function (areas of code that have a single entrance and a single exit) and edges between the blocks to indicate where flow can jump to. Noexcept alters the flow graph.

You asked for a specific example. Consider this code:

void foo(int x) {
    try {
        bar();
        x = 5;
        // Other stuff which doesn't modify x, but might throw
    } catch(...) {
        // Don't modify x
    }

    baz(x); // Or other statement using x
}

The flow graph for this function is different if bar is labeled noexcept (there is no way for execution to jump between the end of bar and the catch statement). When labeled as noexcept, the compiler is certain the value of x is 5 during the baz function - the x=5 block is said to "dominate" the baz(x) block without the edge from bar() to the catch statement.

It can then do something called "constant propagation" to generate more efficient code. Here if baz is inlined, the statements using x might also contain constants and then what used to be a runtime evaluation can be turned into a compile-time evaluation, etc.

Anyway, the short answer: noexcept lets the compiler generate a tighter flow graph, and the flow graph is used to reason about all sorts of common compiler optimizations. To a compiler, user annotations of this nature are awesome. The compiler will try to figure this stuff out, but it usually can't (the function in question might be in another object file not visible to the compiler or transitively use some function which is not visible), or when it does, there is some trivial exception which might be thrown that you're not even aware of, so it can't implicitly label it as noexcept (allocating memory might throw bad_alloc, for example).

Install Tidy2 plugin. I have Notepad++ v6.2.2, and Tidy2 works fine so far.

Deletes all branches that have already been merged into master or develop. Keeps other branches lying around. Will be most conservative with deletions.

Removes branches both locally and in the origin remote.

My answer is repeating what others have said before, but I thought I'd add an example, using MySQL, only because the previous answers were a little bit cryptic to me.

The general form of the command you need to use to update a single row's column:

UPDATE my_table SET my_column='new value' WHERE something='some value';

And here's an example.

BEFORE

mysql> select aet,port from ae;
+------------+-------+
| aet        | port  |
+------------+-------+
| DCM4CHEE01 | 11112 | 
| CDRECORD   | 10104 | 
+------------+-------+
2 rows in set (0.00 sec)

MAKING THE CHANGE

mysql> update ae set port='10105' where aet='CDRECORD';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

AFTER

mysql> select aet,port from ae;
+------------+-------+
| aet        | port  |
+------------+-------+
| DCM4CHEE01 | 11112 | 
| CDRECORD   | 10105 | 
+------------+-------+
2 rows in set (0.00 sec)

In case you don't want (or have) a running container, you can call your script directly with the run command.

Remove the iterative tty -i -t arguments and use this:

    $ docker run ubuntu:bionic /bin/bash /path/to/script.sh

This will (didn't test) also work for other scripts:

    $ docker run ubuntu:bionic /usr/bin/python /path/to/script.py

import urllib2
import time

max_attempts = 80
attempts = 0
sleeptime = 10 #in seconds, no reason to continuously try if network is down

#while true: #Possibly Dangerous
while attempts < max_attempts:
    time.sleep(sleeptime)
    try:
        response = urllib2.urlopen("http://example.com", timeout = 5)
        content = response.read()
        f = open( "local/index.html", 'w' )
        f.write( content )
        f.close()
        break
    except urllib2.URLError as e:
        attempts += 1
        print type(e)

You should have if row[2] != "0". Otherwise it's not checking to see if the string value is equal to 0.

NoSQL is better than RDBMS because of the following reasons/properities of NoSQL

1. It supports semi-structured data and volatile data
2. It does not have schema
3. Read/Write throughput is very high
4. Horizontal scalability can be achieved easily
5. Will support Bigdata in volumes of Terra Bytes & Peta Bytes
6. Provides good support for Analytic tools on top of Bigdata
7. Can be hosted in cheaper hardware machines
8. In-memory caching option is available to increase the performance of queries
9. Faster development life cycles for developers

EDIT:

To answer "why RDBMS cannot scale", please take a look at RDBMS Overheads pdf written by Stavros Harizopoulos,Daniel J. Abadi,Samuel Madden and Michael Stonebraker

RDBMS's have challenges in handling huge data volumes of Terabytes & Peta bytes. Even if you have Redundant Array of Independent/Inexpensive Disks (RAID) & data shredding, it does not scale well for huge volume of data. You require very expensive hardware.

Logging: Assembling log records and tracking down all changes in database structures slows performance. Logging may not be necessary if recoverability is not a requirement or if recoverability is provided through other means (e.g., other sites on the network).

Locking: Traditional two-phase locking poses a sizeable overhead since all accesses to database structures are governed by a separate entity, the Lock Manager.

Latching: In a multi-threaded database, many data structures have to be latched before they can be accessed. Removing this feature and going to a single-threaded approach has a noticeable performance impact.

Buffer management: A main memory database system does not need to access pages through a buffer pool, eliminating a level of indirection on every record access.

This does not mean that we have to use NoSQL over SQL.

Still, RDBMS is better than NoSQL for the following reasons/properties of RDBMS

1. Transactions with ACID properties - Atomicity, Consistency, Isolation & Durability
2. Adherence to Strong Schema of data being written/read
3. Real time query management ( in case of data size < 10 Tera bytes )
4. Execution of complex queries involving join & group by clauses

We have to use RDBMS (SQL) and NoSQL (Not only SQL) depending on the business case & requirements

Actually, in C++14 it can be done with a very few lines of code.

This is a very similar in idea to @Paul's solution. Due to things missing from C++11, that solution is a bit unnecessarily bloated (plus defining in std smells). Thanks to C++14 we can make it a lot more readable.

The key observation is that range-based for-loops work by relying on begin() and end() in order to acquire the range's iterators. Thanks to ADL, one doesn't even need to define their custom begin() and end() in the std:: namespace.

Here is a very simple-sample solution:

// -------------------------------------------------------------------
// --- Reversed iterable

template <typename T>
struct reversion_wrapper { T& iterable; };

template <typename T>
auto begin (reversion_wrapper<T> w) { return std::rbegin(w.iterable); }

template <typename T>
auto end (reversion_wrapper<T> w) { return std::rend(w.iterable); }

template <typename T>
reversion_wrapper<T> reverse (T&& iterable) { return { iterable }; }

This works like a charm, for instance:

template <typename T>
void print_iterable (std::ostream& out, const T& iterable)
{
    for (auto&& element: iterable)
        out << element << ',';
    out << '\n';
}

int main (int, char**)
{
    using namespace std;

    // on prvalues
    print_iterable(cout, reverse(initializer_list<int> { 1, 2, 3, 4, }));

    // on const lvalue references
    const list<int> ints_list { 1, 2, 3, 4, };
    for (auto&& el: reverse(ints_list))
        cout << el << ',';
    cout << '\n';

    // on mutable lvalue references
    vector<int> ints_vec { 0, 0, 0, 0, };
    size_t i = 0;
    for (int& el: reverse(ints_vec))
        el += i++;
    print_iterable(cout, ints_vec);
    print_iterable(cout, reverse(ints_vec));

    return 0;
}

prints as expected

4,3,2,1,
4,3,2,1,
3,2,1,0,
0,1,2,3,

NOTE std::rbegin(), std::rend(), and std::make_reverse_iterator() are not yet implemented in GCC-4.9. I write these examples according to the standard, but they would not compile in stable g++. Nevertheless, adding temporary stubs for these three functions is very easy. Here is a sample implementation, definitely not complete but works well enough for most cases:

// --------------------------------------------------
template <typename I>
reverse_iterator<I> make_reverse_iterator (I i)
{
    return std::reverse_iterator<I> { i };
}

// --------------------------------------------------
template <typename T>
auto rbegin (T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

// const container variants

template <typename T>
auto rbegin (const T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (const T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

• You can create a New Issue

• Copy the images URL and paste it into your README.md file.

here is a detailed youTube video explained this in detail:

Use a shared container to transfer data between threads.

I've found timezone.make_aware(datetime.datetime.now()) is helpful in django (I'm on 1.9.1). Unfortunately you can't simply make a datetime object offset-aware, then timetz() it. You have to make a datetime and make comparisons based on that.

Try... for YUI

Dom.get("gadget_url").set("value","");

with normal Javascript

document.getElementById('gadget_url').value = '';

with JQuery

$("#gadget_url").val("");

One more solution is to use contains which will return true or false

_.contains($(".right-tree").css("background-image"), "stage1")

Hope this helps

UPDATED

I've updated your demo: http://jsfiddle.net/terryyounghk/QS56z/18/

Also, I've changed two ^= to *=. See http://api.jquery.com/category/selectors/

And note the :checked selector. See http://api.jquery.com/checked-selector/

function createcodes() {

    //run through each row
    $('.authors-list tr').each(function (i, row) {

        // reference all the stuff you need first
        var $row = $(row),
            $family = $row.find('input[name*="family"]'),
            $grade = $row.find('input[name*="grade"]'),
            $checkedBoxes = $row.find('input:checked');

        $checkedBoxes.each(function (i, checkbox) {
            // assuming you layout the elements this way, 
            // we'll take advantage of .next()
            var $checkbox = $(checkbox),
                $line = $checkbox.next(),
                $size = $line.next();

            $line.val(
                $family.val() + ' ' + $size.val() + ', ' + $grade.val()
            );

        });

    });
}

Currently there is another approach possible if classes are used in code.

With support of class fields it's possible to make it next way:

class someView {
    onSomeInputKeyUp = (event) => {
        console.log(this); // this refers to correct value
    // ....
    someInitMethod() {
        //...
        someInput.addEventListener('input', this.onSomeInputKeyUp)

For sure under the hood it's all old good arrow function that bind context but in this form it looks much more clear that explicit binding.

Since it's Stage 3 Proposal you will need babel and appropriate babel plugin to process it as for now(08/2018).

Since defineProperty has browser compatibility issue, I think we can think about using a service.

angular.module('myservice', [], function($provide) {
    $provide.factory('msgBus', ['$rootScope', function($rootScope) {
        var msgBus = {};
        msgBus.emitMsg = function(msg) {
        $rootScope.$emit(msg);
        };
        msgBus.onMsg = function(msg, scope, func) {
            var unbind = $rootScope.$on(msg, func);
            scope.$on('$destroy', unbind);
        };
        return msgBus;
    }]);
});

and use it in controller like this:

• controller 1

  function($scope, msgBus) {
      $scope.sendmsg = function() {
          msgBus.emitMsg('somemsg')
      }
  }
  

• controller 2

  function($scope, msgBus) {
      msgBus.onMsg('somemsg', $scope, function() {
          // your logic
      });
  }
  

Use LINQ Aggregate method to convert array of integers to a comma separated string

var intArray = new []{1,2,3,4};
string concatedString = intArray.Aggregate((a, b) =>Convert.ToString(a) + "," +Convert.ToString( b));
Response.Write(concatedString);

output will be

1,2,3,4

This is one of the solution you can use if you have not .net 4 installed.

It should work. Try this

var label:UILabel = UILabel(frame: CGRectMake(10
    ,100, 300, 40));
label.textAlignment = NSTextAlignment.Center;
label.numberOfLines = 0;
label.font = UIFont.systemFontOfSize(16.0);
label.text = "First label\nsecond line";
self.view.addSubview(label);

Update 2020

Products are located mainly in the following tables:

• wp_posts table with post_type like product (or product_variation),

• wp_postmeta table with post_id as relational index (the product ID).

• wp_wc_product_meta_lookup table with product_id as relational index (the post ID) | Allow fast queries on specific product data (since WooCommerce 3.7)

• wp_wc_order_product_lookuptable with product_id as relational index (the post ID) | Allow fast queries to retrieve products on orders (since WooCommerce 3.7)

Product types, categories, subcategories, tags, attributes and all other custom taxonomies are located in the following tables:

• wp_terms

• wp_termmeta

• wp_term_taxonomy

• wp_term_relationships - column object_id as relational index (the product ID)

• wp_woocommerce_termmeta

• wp_woocommerce_attribute_taxonomies (for product attributes only)

• wp_wc_category_lookup (for product categories hierarchy only since WooCommerce 3.7)

Product types are handled by custom taxonomy product_type with the following default terms:

• simple
• grouped
• variable
• external

Some other product types for Subscriptions and Bookings plugins:

• subscription
• variable-subscription
• booking

Since Woocommerce 3+ a new custom taxonomy named product_visibility handle:

• The product visibility with the terms exclude-from-search and exclude-from-catalog
• The feature products with the term featured
• The stock status with the term outofstock
• The rating system with terms from rated-1 to rated-5

Particular feature: Each product attribute is a custom taxonomy…

References:

• Normal tables: Wordpress database description
• Specific tables: Woocommerce database description

This worked for me

//Sentence has quotes
string nameSentence = "Take my name \"Wesley\" out of quotes";
//Get the index before the quotes`enter code here`
int begin = nameSentence.LastIndexOf("name") + "name".Length;
//Get the index after the quotes
int end = nameSentence.LastIndexOf("out");
//Get the part of the string with its quotes
string name = nameSentence.Substring(begin, end - begin);
//Remove its quotes
string newName = name.Replace("\"", "");
//Replace new name (without quotes) within original sentence
string updatedNameSentence = nameSentence.Replace(name, newName);

//Returns "Take my name Wesley out of quotes"
return updatedNameSentence;

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

Try this,

get-music:
 rsync -avzru --delete-excluded server:/media/10001/music/ /media/Incoming/music/

put-music:
 rsync -avzru --delete-excluded /media/Incoming/music/ server:/media/10001/music/

sync-music: get-music put-music

I just test this and it worked for me. I'm doing a 2-way sync between Windows7 (using cygwin with the rsync package installed) and FreeNAS fileserver (FreeNAS runs on FreeBSD with rsync package pre-installed).

    int scrWidth  = getWindowManager().getDefaultDisplay().getWidth();
    int scrHeight = getWindowManager().getDefaultDisplay().getHeight();

It depends what you wanted to do with that column e.g. here's an example of appending a new column to a recordset which can be updated on the client side:

Sub MSDataShape_AddNewCol()

  Dim rs As ADODB.Recordset
  Set rs = CreateObject("ADODB.Recordset")
  With rs
    .ActiveConnection = _
    "Provider=MSDataShape;" & _
    "Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Tempo\New_Jet_DB.mdb"
    .Source = _
    "SHAPE {" & _
    " SELECT ExistingField" & _
    " FROM ExistingTable" & _
    " ORDER BY ExistingField" & _
    "} APPEND NEW adNumeric(5, 4) AS NewField"

    .LockType = adLockBatchOptimistic

    .Open

    Dim i As Long
    For i = 0 To .RecordCount - 1
      .Fields("NewField").Value = Round(.Fields("ExistingField").Value, 4)
      .MoveNext
    Next

    rs.Save "C:\rs.xml", adPersistXML

  End With
End Sub

Looks like the secret key isn't on the other machine, so even with the right passphrase (read from a file) it wouldn't work.

These options should work, to

• Either copy the keyrings (maybe only secret keyring required, but public ring is public anyway) over to the other machine
• Or export the secret key & then import it on the other machine

A few useful looking options from man gpg:

--export
Either export all keys from all keyrings (default keyrings and those registered via option --keyring), or if at least one name is given, those of the given name. The new keyring is written to STDOUT or to the file given with option --output. Use together with --armor to mail those keys.

--export-secret-keys
Same as --export, but exports the secret keys instead.

--import
--fast-import
Import/merge keys. This adds the given keys to the keyring. The fast version is currently just a synonym.

And maybe

--keyring file
Add file to the current list of keyrings. If file begins with a tilde and a slash, these are replaced by the $HOME directory. If the file- name does not contain a slash, it is assumed to be in the GnuPG home directory ("~/.gnupg" if --homedir or $GNUPGHOME is not used).

Note that this adds a keyring to the current list. If the intent is to use the specified keyring alone, use --keyring along with --no-default-keyring.

--secret-keyring file
Same as --keyring but for the secret keyrings.

It's probably worth noting that Groovy has this feature:

import java.util.Calendar
import com.example.Calendar as MyCalendar

MyCalendar myCalendar = new MyCalendar()

It is possible. You can have the download started from inside an ajax function, for example, just after the .csv file is created.

I have an ajax function that exports a database of contacts to a .csv file, and just after it finishes, it automatically starts the .csv file download. So, after I get the responseText and everything is Ok, I redirect browser like this:

window.location="download.php?filename=export.csv";

My download.php file looks like this:

<?php

    $file = $_GET['filename'];

    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Disposition: attachment; filename=".$file."");
    header("Content-Transfer-Encoding: binary");
    header("Content-Type: binary/octet-stream");
    readfile($file);

?>

There is no page refresh whatsoever and the file automatically starts downloading.

NOTE - Tested in the following browsers:

Chrome v37.0.2062.120 
Firefox v32.0.1
Opera v12.17
Internet Explorer v11

You are looking for strval:

string strval ( mixed $var )

Get the string value of a variable. See the documentation on string for more information on converting to string.

This function performs no formatting on the returned value. If you are looking for a way to format a numeric value as a string, please see sprintf() or number_format().

In addition, if you have migrated your user files and applications from one mac to another, you need to install Apple Developer Tools all over again. The migration assistant does not account for the developer tools installation.

There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:

It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

This worked in my case (only tested in modern browsers):

.textthatneedstobecentered {
  margin: auto;
  top: 0; bottom: 0;
}

To meet these criteria: modify original list in situ, no list copies, only one pass, works, a traditional solution is to iterate backwards:

for i in xrange(len(somelist) - 1, -1, -1):
    element = somelist[i]
    do_action(element)
    if check(element):
        del somelist[i]

Bonus: Doesn't do len(somelist) on each iteration. Works on any version of Python (at least as far back as 1.5.2) ... s/xrange/range/ for 3.X.

Update: If you want to iterate forwards, it's possible, just trickier and uglier:

i = 0
n = len(somelist)
while i < n:
    element = somelist[i]
    do_action(element)
    if check(element):
        del somelist[i]
        n = n - 1
    else:
        i = i + 1

I followed Mingcai SHEN's method.

But in my case, I changed the connector to

connector = C:\Program Files\MySQL\MySQL Connector.C 6.1

And the library_dirs is changed to

library_dirs = [ os.path.join(connector, r'lib\vs10') ]

because I don't have a vs9 directory. It works, but I don't know why.

I have vs2012 installed, and the lib directory of the connector only has vs10 and vs11, in which vs11 doesn't work. The VCForPyhton27.mis I installed seems to support vs9.

Anyway, this works. And if you want to risk it, you can try.

ArrayUtils.indexOf(array, value);
Ints.indexOf(array, value);
Arrays.asList(array).indexOf(value);

Well, your code is not reproducible so we will never know for sure, but this is what help('break')says:

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.

So yes, break only breaks the current loop. You can also see it in action with e.g.:

for (i in 1:10)
{
    for (j in 1:10)
    {
        for (k in 1:10)
        {
            cat(i," ",j," ",k,"\n")
            if (k ==5) break
        }   
    }
}

There are three ways to save objects from your R session:

Saving all objects in your R session:

The save.image() function will save all objects currently in your R session:

save.image(file="1.RData") 

These objects can then be loaded back into a new R session using the load() function:

load(file="1.RData")

Saving some objects in your R session:

If you want to save some, but not all objects, you can use the save() function:

save(city, country, file="1.RData")

Again, these can be reloaded into another R session using the load() function:

load(file="1.RData") 

Saving a single object

If you want to save a single object you can use the saveRDS() function:

saveRDS(city, file="city.rds")
saveRDS(country, file="country.rds") 

You can load these into your R session using the readRDS() function, but you will need to assign the result into a the desired variable:

city <- readRDS("city.rds")
country <- readRDS("country.rds")

But this also means you can give these objects new variable names if needed (i.e. if those variables already exist in your new R session but contain different objects):

city_list <- readRDS("city.rds")
country_vector <- readRDS("country.rds")

You can use the following Code to retain Integers from String.

String text="Hello1010";
System.out.println(CharMatcher.digit().retainFrom(text));

Will give you the Following Output

1010

Is required that you have a form?
If not, then you could use this:

<div>
    <input type="hidden" value="ServletParameter" />
    <input type="button" id="callJavaScriptServlet" onclick="callJavaScriptServlet()" />
</div>

with the following JavaScript:

function callJavaScriptServlet() {
    this.form.action = "MyServlet";
    this.form.submit();
}

To change the color for above lolipop just add this to your styles.xml

<item name="android:statusBarColor">@color/statusBarColor</item>

but remember, if you want to have a light color for the status bar, add this line too

<item name="android:windowLightStatusBar">true</item>

You have pylab.ylim:

pylab.ylim([0,1000])

Note: The command has to be executed after the plot!

Update 2021
Since the use of pylab is now strongly discouraged by matplotlib, you should instead use pyplot:

from matplotlib import pyplot as plt
plt.ylim(0, 100) 
#corresponding function for the x-axis
plt.xlim(1, 1000)

No. Its not possible to add link through css. But you can use jquery

$('.case').each(function() {
  var link = $(this).html();
  $(this).contents().wrap('<a href="example.com/script.php?id="></a>');
});

Here the demo: http://jsfiddle.net/r5uWX/1/

Your onClick request:

<span class="A" onclick="var state = this.className.indexOf('A') > -1; $(this).toggleClass('A', !state).toggleClass('B', state);">Click Me</span>

Try it: https://jsfiddle.net/v15q6b5y/

Just the JS à la jQuery:

$('.selector').toggleClass('A', !state).toggleClass('B', state);

Based on the instructions at the link below, do the following.

In VBA insert a new module and paste in this code:

Public Function UserName()
    UserName = Environ$("UserName")
End Function

Call the function using the formula:

=Username()

Based on instructions at:

The last choice is the best.

If you want a version that raises an error:

"string to search".index("needle") 

If you want a version that returns -1:

"string to search".find("needle") 

This is more efficient than the 'in' syntax

As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.

var mockFileBrowser = new Mock<FileBrowser>();

instead of

var mockFileBrowser = new Mock<IFileBrowser>();

As no one has mentioned, another way to create a String out of a single char:

String s = Character.toString('X');

Returns a String object representing the specified char. The result is a string of length 1 consisting solely of the specified char.

You may also try to use the serialize() function. Sometimes it is very useful for debugging purposes.

A much cleaner, safer answer to this problem (you really shouldn't hard code Strings):

public void openInGallery(String imageId) {
  Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI.buildUpon().appendPath(imageId).build();
  Intent intent = new Intent(Intent.ACTION_VIEW, uri);
  startActivity(intent);
}

All you have to do is append the image id to the end of the path for the EXTERNAL_CONTENT_URI. Then launch an Intent with the View action, and the Uri.

The image id comes from querying the content resolver.

This will verify if the function exists, if so it will be executed

me.onChange && me.onChange(str);

Thus the error TypeError: me.onChange is not a function is prevent.

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

There is a batch file called resetroot.bat located in the xammp folders 'C:\xampp\mysql' run this and it will delete the phpmyadmin passwords. Then all you need to do is start the MySQL service in xamp and click the admin button.

Try this css

}

ul.nav {
    float: none;

}

It's tangential, but here's a tip for those using Rackt's React Router library with (HTML5) browser history who want to host on S3.

Suppose a user visits /foo/bear at your S3-hosted static web site. Given David's earlier suggestion, redirect rules will send them to /#/foo/bear. If your application's built using browser history, this won't do much good. However your application is loaded at this point and it can now manipulate history.

Including Rackt history in our project (see also Using Custom Histories from the React Router project), you can add a listener that's aware of hash history paths and replace the path as appropriate, as illustrated in this example:

import ReactDOM from 'react-dom';

/* Application-specific details. */
const route = {};

import { Router, useRouterHistory } from 'react-router';
import { createHistory } from 'history';

const history = useRouterHistory(createHistory)();

history.listen(function (location) {
  const path = (/#(\/.*)$/.exec(location.hash) || [])[1];
  if (path) history.replace(path);
});

ReactDOM.render(
  <Router history={history} routes={route}/>,
  document.body.appendChild(document.createElement('div'))
);

To recap:

1. David's S3 redirect rule will direct /foo/bear to /#/foo/bear.
2. Your application will load.
3. The history listener will detect the #/foo/bear history notation.
4. And replace history with the correct path.

Link tags will work as expected, as will all other browser history functions. The only downside I've noticed is the interstitial redirect that occurs on initial request.

This was inspired by a solution for AngularJS, and I suspect could be easily adapted to any application.

You can do this with "just the regular expression" as you asked for in a comment:

(?<=sentence).*

(?<=sentence) is a positive lookbehind assertion. This matches at a certain position in the string, namely at a position right after the text sentence without making that text itself part of the match. Consequently, (?<=sentence).* will match any text after sentence.

This is quite a nice feature of regex. However, in Java this will only work for finite-length subexpressions, i. e. (?<=sentence|word|(foo){1,4}) is legal, but (?<=sentence\s*) isn't.

I don't know if it will work on .NET 2.0, but it worked me on .NET 4.5.2. Here is the code:

using System;
using System.Drawing;
using System.Windows.Forms;

public partial class Your_Form_Name : Form
{
    public Your_Form_Name()
    {
        InitializeComponent();
    }

    // CODE STARTS HERE

    private System.Drawing.Size oldsize = new System.Drawing.Size(300, 300);
    private System.Drawing.Point oldlocation = new System.Drawing.Point(0, 0);
    private System.Windows.Forms.FormWindowState oldstate = System.Windows.Forms.FormWindowState.Normal;
    private System.Windows.Forms.FormBorderStyle oldstyle = System.Windows.Forms.FormBorderStyle.Sizable;
    private bool fullscreen = false;
    /// <summary>
    /// Goes to fullscreen or the old state.
    /// </summary>
    private void UpgradeFullscreen()
    {
        if (!fullscreen)
        {
            oldsize = this.Size;
            oldstate = this.WindowState;
            oldstyle = this.FormBorderStyle;
            oldlocation = this.Location;
            this.WindowState = System.Windows.Forms.FormWindowState.Normal;
            this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
            this.Bounds = System.Windows.Forms.Screen.PrimaryScreen.Bounds;
            fullscreen = true;
        }
        else
        {
            this.Location = oldlocation;
            this.WindowState = oldstate;
            this.FormBorderStyle = oldstyle;
            this.Size = oldsize;
            fullscreen = false;
        }
    }

    // CODE ENDS HERE
}

Usage:

UpgradeFullscreen(); // Goes to fullscreen
UpgradeFullscreen(); // Goes back to normal state
// You don't need arguments.

Notice: You MUST place it inside your Form's class (Example: partial class Form1 : Form { /* Code goes here */ } ) or it will not work because if you don't place it on any form, code this will create an exception.

Well, first, you need to actually define a function before you can run it (and it doesn't need to be called main). For instance:

class Example(object):
    def run(self):
        print "Hello, world!"

if __name__ == '__main__':
    Example().run()

You don't need to use a class, though - if all you want to do is run some code, just put it inside a function and call the function, or just put it in the if block:

def main():
    print "Hello, world!"

if __name__ == '__main__':
    main()

or

if __name__ == '__main__':
    print "Hello, world!"

This would also work :

import 'package:http/http.dart' as http;

  sendRequest() async {

    Map data = {
       'apikey': '12345678901234567890'
    };

    var url = 'https://pae.ipportalegre.pt/testes2/wsjson/api/app/ws-authenticate';
    http.post(url, body: data)
        .then((response) {
      print("Response status: ${response.statusCode}");
      print("Response body: ${response.body}");
    });  
  }

To get the new Microsoft Edge based on a Mozilla core add:

else if ((verOffset=nAgt.indexOf("Edg"))!=-1) {
 browserName = "Microsoft Edge";
 fullVersion = nAgt.substring(verOffset+5);
}

before

// In Chrome, the true version is after "Chrome" 
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {
 browserName = "Chrome";
 fullVersion = nAgt.substring(verOffset+7);
}

I don't know your test conditions, but a good old switch could work

switch(colour)
{
  case red:
  {
    switch(car)
    { 
      case hyundai: 
      {
        break;
      }
      :
    }
    break;
  }
  :
}

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

if(isset($_SESSION['SESS_fname'])){
    echo $_SESSION['SESS_fname'];
}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

be aware that this is dangerous:

WHERE `column` LIKE '%{$needle}%'

do first:

$needle = mysql_real_escape_string($needle);

so it will prevent possible attacks.

I know this is a pretty old thread, but I was searching for something similar and came up with this.

Given that you had a comma-separated string, you could use string_split

select distinct value from string_split('1, 1, 1, 2, 5, 1, 6',',')

This should return

1
2
5
6

String split takes two parameters, the string input, and the separator character.

you can add an optional where statement using value as the column name

select distinct value from string_split('1, 1, 1, 2, 5, 1, 6',',')
where value > 1

produces

2
5
6

My problem was in my XML lyout I have an android:animateLayoutChanges set to true and I've called notifyDataSetChanged() on the RecyclerView's adapter in the Java code.

So, I've just removed android:animateLayoutChanges from my layout and that resloved my problem.

I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;

It works and it's cross browser compatible.

Check out the code below, you probably get a better explanation:

We're doing this to create thumbnails of images:

  BufferedImage tThumbImage = new BufferedImage( tThumbWidth, tThumbHeight, BufferedImage.TYPE_INT_RGB );
  Graphics2D tGraphics2D = tThumbImage.createGraphics(); //create a graphics object to paint to
  tGraphics2D.setBackground( Color.WHITE );
  tGraphics2D.setPaint( Color.WHITE );
  tGraphics2D.fillRect( 0, 0, tThumbWidth, tThumbHeight );
  tGraphics2D.setRenderingHint( RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR );
  tGraphics2D.drawImage( tOriginalImage, 0, 0, tThumbWidth, tThumbHeight, null ); //draw the image scaled

  ImageIO.write( tThumbImage, "JPG", tThumbnailTarget ); //write the image to a file

I got it work by overriding annotation with XML file for Postgres. Annotation is kept for Oracle. In my opinion, in this case it would be best we override the mapping of this trouble-some enity with xml mapping. We can override single / multiple entities with xml mapping. So we would use annotation for our mainly-supported database, and a xml file for each other database.

Note: we just need to override one single class , so it is not a big deal. Read more from my example Example to override annotation with XML

Adding/Removing value dynamically without hard-code:

// remove value from select dynamically

$("#id-select option[value='" + dynamicVal + "']").remove();

// Add dynamic value to select

$("#id-select").append('<option value="' + dynamicVal + '">' + dynamicVal + '</option>');

If swfobject won't suffice, or you need to create something a little more bespoke, try this:

var hasFlash = false;
try {
    hasFlash = Boolean(new ActiveXObject('ShockwaveFlash.ShockwaveFlash'));
} catch(exception) {
    hasFlash = ('undefined' != typeof navigator.mimeTypes['application/x-shockwave-flash']);
}

It works with 7 and 8.

You can use the below simple method of sorting:

datatable.DefaultView.Sort = "Col2 ASC,Col3 ASC,Col4 ASC";

By the above method, you will be able to sort N number of columns.

This will show the changes in files:

git diff --word-diff SHA1 SHA2

// This is for normal triangle

for (int i = 0; i < 5; i++)
        {
            for (int j = 5; j > i; j--)
            {
                System.out.print(" ");
            }
            for (int k = 1; k <= i + 1; k++) {
                System.out.print(" *");
            }
            System.out.print("\n");
        }

// This is for left triangle, just removed space before printing *

for (int i = 0; i < 5; i++)
        {
            for (int j = 5; j > i; j--)
            {
                System.out.print(" ");
            }
            for (int k = 1; k <= i + 1; k++) {
                System.out.print("*");
            }
            System.out.print("\n");
        }

@Inject has no 'required' attribute

To get the negation, do this ...

df.filter(not( ..expression.. ))

eg

df.filter(not($"state" === "TX"))

I had a similar problem.

Issue was there was a trigger on the table that would write changes to an audit log table. Columns were missing in audit log table.

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

To run function onLoad

jQuery(window).on("load", function(){
    ..code..
});

To run code onDOMContentLoaded (also called onready)

jQuery(document).ready(function(){
    ..code..
});

or the recommended shorthand for onready

jQuery(function($){
    ..code.. ($ is the jQuery object)
});

onready fires when the document has loaded

onload fires when the document and all the associated content, like the images on the page have loaded.

Another way to do it is just to use the sendRedirect method:

@RequestMapping(
    value = "/",
    method = RequestMethod.GET)
public void redirectToTwitter(HttpServletResponse httpServletResponse) throws IOException {
    httpServletResponse.sendRedirect("https://twitter.com");
}

I ran into this and realized I didn't fetch the upstream before trying to rebase. All I needed was to git fetch upstream

https://docs.python.org/2/library/csv.html?highlight=csv#csv.reader

csvfile can be any object which supports the iterator protocol and returns a string each time its next() method is called

Thus, a StringIO.StringIO(), str.splitlines() or even a generator are all good.

use "LEFT"

 select left('Hello World', 5)

or use "SUBSTRING"

 select substring('Hello World', 1, 5)

This is just a suggestion, but what I like to do while I'm coding sometimes is to Invert the colors of my Screen. On a Mac it's Ctrl-Cmd-Alt->8 and it inverts the colors.

Haven't personally tried these in Idea10, but it worked on Idea9. http://devnet.jetbrains.net/docs/DOC-1154

If you use the java keyword abstract you cannot provide an implementation.

Sometimes this idea comes from having a background in C++ and mistaking the virtual keyword in C++ as being "almost the same" as the abstract keyword in Java.

In C++ virtual indicates that a method can be overridden and polymorphism will follow, but abstract in Java is not the same thing. In Java abstract is more like a pure virtual method, or one where the implementation must be provided by a subclass. Since Java supports polymorphism without the need to declare it, all methods are virtual from a C++ point of view. So if you want to provide a method that might be overridden, just write it as a "normal" method.

Now to protect a method from being overridden, Java uses the keyword final in coordination with the method declaration to indicate that subclasses cannot override the method.

I presume you meant false instead of 'false'

Also, [disabled] is expecting a Boolean. You should avoid returning a null.

For the case where git rm doesn't suffice and the file needs to be removed from history: As the git filter-branch manual page now itself suggests using git-filter-repo, and I had to do this today, here's an example using that tool. It uses the example repo https://example/eguser/eg.git

1. Clone the repository into a new directory git clone https://example/eguser/eg.git

2. Keep everything except the unwanted file. git-filter-repo --path file1.txt --invert-paths

3. Add the remote repository origin back : git remote add origin https://example/eguser/eg.git. The git-filter-repo tool removes remote remote info by design and suggests a new remote repo (see point 4). This makes sense for big shared repos but might be overkill for getting rid a single newly added file as in this example.

4. When happy with the contents of local, replace remote with it.

   git push --force -u origin master. Forcing is required due to the changed history.

Also note the useful --dry-run option and a good discussion in the linked manual on team and project dynamics before charging in and changing repository history.

list1 = [1,2,3,4]; list2 = [0,3,3,6]

print set(list2) - set(list1)

For me, it was all about setting up my web server to use the latest-and-greatest tech to support my ASP.NET 5 application!

The following URL gave me all the tips I needed:

Hope this helps :)

if it doesn't work after chmod'ing make sure you aren't trying to execute it inside the /tmp directory.

An alternative approach is resample, which can handle duplicate dates in addition to missing dates. For example:

df.resample('D').mean()

resample is a deferred operation like groupby so you need to follow it with another operation. In this case mean works well, but you can also use many other pandas methods like max, sum, etc.

Here is the original data, but with an extra entry for '2013-09-03':

             val
date           
2013-09-02     2
2013-09-03    10
2013-09-03    20    <- duplicate date added to OP's data
2013-09-06     5
2013-09-07     1

And here are the results:

             val
date            
2013-09-02   2.0
2013-09-03  15.0    <- mean of original values for 2013-09-03
2013-09-04   NaN    <- NaN b/c date not present in orig
2013-09-05   NaN    <- NaN b/c date not present in orig
2013-09-06   5.0
2013-09-07   1.0

I left the missing dates as NaNs to make it clear how this works, but you can add fillna(0) to replace NaNs with zeroes as requested by the OP or alternatively use something like interpolate() to fill with non-zero values based on the neighboring rows.

I know it's an old thread, but I just looked into schemas myself and think the following could be another good candidate for schema usage:

In a Datawarehouse, with data coming from different sources, you can use a different schema for each source, and then e.g. control access based on the schemas. Also avoids the possible naming collisions between the various source, as another poster replied above.

Applying a CORS restriction is a security feature defined by a server and implemented by a browser.

The browser looks at the CORS policy of the server and respects it.

However, the Postman tool does not bother about the CORS policy of the server.

That is why the CORS error appears in the browser, but not in Postman.

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

Your guess is the correct one. The only thing you have to remember is that the member function template definition (in addition to the declaration) should be in the header file, not the cpp, though it does not have to be in the body of the class declaration itself.

If your OS is Windows, then it is very simple. When you install Android Studio, adb.exe is located in the following folder:

C:\Users\**your-user-name**\AppData\Local\Android\Sdk\platform-tools

Copy the path and paste in your environment variables.

Open your terminal and type: adb it's done!

I'm from Brazil and I create my data bases using latin1_spanish_ci. For the html and everything else I use:

charset=ISO-8859-1

The data goes right with é,ã and ç... Sometimes I have to put the texts of the html using the code of it, such as:

Olá

gives me

Olá

You can find the codes in this page: http://www.ascii.cl/htmlcodes.htm

Hope this helps. I remember it was REALLY annoying.

This is a version when you have an object and an array and you want to merge them and give the array a key value so it fits into the object nicely.

var fileData = [_x000D_
    { "id" : "1", "filename" : "myfile1", "score" : 33.1 }, _x000D_
    { "id" : "2", "filename" : "myfile2", "score" : 31.4 }, _x000D_
    { "id" : "3", "filename" : "myfile3", "score" : 36.3 }, _x000D_
    { "id" : "4", "filename" : "myfile4", "score" : 23.9 }_x000D_
];_x000D_
_x000D_
var fileQuality = [0.23456543,0.13413131,0.1941344,0.7854522];_x000D_
_x000D_
var newOjbect = fileData.map((item, i) => Object.assign({}, item, {fileQuality:fileQuality[i]}));_x000D_
_x000D_
console.log(newOjbect);

You can use the :before pseudo-selector to insert content in front of the list item. You can find an example on Quirksmode, at http://www.quirksmode.org/css/beforeafter.html. I use this to insert giant quotes around blockquotes...

HTH.

Here is a VB.NET solution based on ShravankumarKumar's solution.

This will ONLY give you the text. The images are a different story.

Public Shared Function GetTextFromPDF(PdfFileName As String) As String
    Dim oReader As New iTextSharp.text.pdf.PdfReader(PdfFileName)

    Dim sOut = ""

    For i = 1 To oReader.NumberOfPages
        Dim its As New iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy

        sOut &= iTextSharp.text.pdf.parser.PdfTextExtractor.GetTextFromPage(oReader, i, its)
    Next

    Return sOut
End Function

Also, you can de-serialize data into an object. This doesn't go through the class Constructor !

UPDATED : Thanks Tom for pointing that out in your comment ! And Michael also experimented.

It goes through the constructor of the most derived non-serializable superclass.
And when that class has no no-args constructor, a InvalidClassException is thrown upon de-serialization.

Please see Tom's answer for a complete treatment of all cases ;-)
is there any other way of creating an object without using "new" keyword in java

Anything that is static is in the class level. You don't have to create instance to access static fields/method. Static variable will be created once when class is loaded.

Instance variables are the variable associated with the object which means that instance variables are created for each object you create. All objects will have separate copy of instance variable for themselves.

In your case, when you declared it as static final, that is only one copy of variable. If you change it from multiple instance, the same variable would be updated (however, you have final variable so it cannot be updated).

In second case, the final int a is also constant , however it is created every time you create an instance of the class where that variable is declared.

Have a look on this Java tutorial for better understanding ,

Boost provides a string algorithm for this:

#include <boost/algorithm/string.hpp>

std::string str = "HELLO, WORLD!";
boost::algorithm::to_lower(str); // modifies str

Or, for non-in-place:

#include <boost/algorithm/string.hpp>

const std::string str = "HELLO, WORLD!";
const std::string lower_str = boost::algorithm::to_lower_copy(str);

enumerate is what you want:

for i, s in enumerate(S):
    print s, i

 $('#checkall').on("click",function(){
      $('.chk').trigger("click");
   });

The few lines you posted from your script look okay to me. It's probably something a bit deeper.

You need to find which line is giving you this error. Add set -xv to the top of your script. This will print out the line number and the command that's being executed to STDERR. This will help you identify where in your script you're getting this particular error.

BTW, do you have a shebang at the top of your script? When I see something like this, I normally expect its an issue with the Shebang. For example, if you had #! /bin/bash on top, but your bash interpreter is located in /usr/bin/bash, you'll see this error.

EDIT

New question: How can I save the file correctly in the first place, to avoid having to perform this fix every time I resend the file?

Two ways:

1. Select the Edit->EOL Conversion->Unix Format menu item when you edit a file. Once it has the correct line endings, Notepad++ will keep them.
2. To make sure all new files have the correct line endings, go to the Settings->Preferences menu item, and pull up the Preferences dialog box. Select the New Document/Default Directory tab. Under New Document and Format, select the Unix radio button. Click the Close button.

With xidel:

curl <...> | xidel - -se '$json'

xidel can probably retrieve the JSON for you as well.

If using insert ignore having a SHOW WARNINGS; statement at the end of your query set will show a table with all the warnings, including which IDs were the duplicates.

A great C# example of declarative vs. imperative programming is LINQ.

With imperative programming, you tell the compiler what you want to happen, step by step.

For example, let's start with this collection, and choose the odd numbers:

List<int> collection = new List<int> { 1, 2, 3, 4, 5 };

With imperative programming, we'd step through this, and decide what we want:

List<int> results = new List<int>();
foreach(var num in collection)
{
    if (num % 2 != 0)
          results.Add(num);
}

Here, we're saying:

1. Create a result collection
2. Step through each number in the collection
3. Check the number, if it's odd, add it to the results

With declarative programming, on the other hand, you write code that describes what you want, but not necessarily how to get it (declare your desired results, but not the step-by-step):

var results = collection.Where( num => num % 2 != 0);

Here, we're saying "Give us everything where it's odd", not "Step through the collection. Check this item, if it's odd, add it to a result collection."

In many cases, code will be a mixture of both designs, too, so it's not always black-and-white.

Setting the CLASSPATH System Variable

To display the current CLASSPATH variable, use these commands in Windows and UNIX (Bourne shell): In Windows: C:\> set CLASSPATH In UNIX: % echo $CLASSPATH

To delete the current contents of the CLASSPATH variable, use these commands: In Windows: C:\> set CLASSPATH= In UNIX: % unset CLASSPATH; export CLASSPATH

To set the CLASSPATH variable, use these commands (for example): In Windows: C:\> set CLASSPATH=C:\users\george\java\classes In UNIX: % CLASSPATH=/home/george/java/classes; export CLASSPATH

Approximate solution:

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.font = "100px Arial";
var txt = "Hello guys!"
var wt = ctx.measureText(txt).width;
var height = wt / txt.length;

This will be accurate result in monospaced font.

Chrome will never implement support RTSP streaming.

At least, in the words of a Chromium developer here:

we're never going to add support for this

Below code works for me in Angular 4

import { FormBuilder, FormGroup, Validators } from '@angular/forms';
export class RegisterComponent implements OnInit {
 registerForm: FormGroup; 

 constructor(private formBuilder: FormBuilder) { }   

 ngOnInit() {
    this.registerForm = this.formBuilder.group({
      empname: [''],
      empemail: ['']
    });
 }

 onRegister(){
    //sending data to server using http request
    this.registerForm.reset()
 }

}

It is always preferred to use a virtual environment ,Create your virtual environment using :

python -m venv <name_of_virtualenv>

go to your environment directory and activate your environment using below command on windows:

env_name\Scripts\activate.bat

then simply use

pip install package_name

Using this code you can write to a text file in the SDCard. Along with it, you need to set a permission in the Android Manifest.

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

This is the code :

public void generateNoteOnSD(Context context, String sFileName, String sBody) {
    try {
        File root = new File(Environment.getExternalStorageDirectory(), "Notes");
        if (!root.exists()) {
            root.mkdirs();
        }
        File gpxfile = new File(root, sFileName);
        FileWriter writer = new FileWriter(gpxfile);
        writer.append(sBody);
        writer.flush();
        writer.close();
        Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Before writing files you must also check whether your SDCard is mounted & the external storage state is writable.

Environment.getExternalStorageState()

import numpy as np

myList = np.linspace(0, 100, 1000) #Generates 1000 numbers from 0 to 100 in equal intervals

Try to use .trim() first, before .equals(), or create a new String var that has these things.

Best way to do it without wasting time to order records is like this :

select 0 as tmp,Column1 from Table1 Order by tmp OFFSET 5000000 ROWS FETCH NEXT 50 ROWS ONLY

it takes less than one second!
best solution for large tables.

I recently just ran into this issue as well. I had a very large table in the dialog div. It was >15,000 rows. When the .empty() was called on the dialog div, I was getting the error above.

I found a round-about solution where before I call cleaning the dialog box, I would remove every other row from the very large table, then call the .empty(). It seemed to have worked though. It seems that my old version of JQuery can't handle such large elements.

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

// Make option have a "selected" attribute using jQuery

var yourValue = "Gateway 2";

$("#gate").find('option').each(function( i, opt ) {
    if( opt.value === yourValue ) 
        $(opt).attr('selected', 'selected');
});

var rotator = function(){
  widget.Rotator.rotate();
  setTimeout(rotator,5000);
};
rotator();

Or:

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

I like simbu's approach, but I ain't comfortable to use first-child or last-child. Instead I only modify the content of a repeating list-comma class.

.list-comma + .list-comma::before {
    content: ', ';
}

<span class="list-comma" ng-repeat="destination in destinations">
    {{destination.name}}
</span>

It's part of the Oracle analytic functions.

If you don't know when data will be added to #data, you could set an interval to update the element's scrollTop to its scrollHeight every couple of seconds. If you are controlling when data is added, just call the internal of the following function after the data has been added.

window.setInterval(function() {
  var elem = document.getElementById('data');
  elem.scrollTop = elem.scrollHeight;
}, 5000);

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

You can just run an interactive shell container using that image and explore whatever content that image has.

For instance:

docker run -it image_name sh

Or following for images with an entrypoint

docker run -it --entrypoint sh image_name

Or, if you want to see how the image was build, meaning the steps in its Dockerfile, you can:

docker image history --no-trunc image_name > image_history

The steps will be logged into the image_history file.

awk '{ sum += $2; n++ } END { if (n > 0) print sum / n; }'

Add the numbers in $2 (second column) in sum (variables are auto-initialized to zero by awk) and increment the number of rows (which could also be handled via built-in variable NR). At the end, if there was at least one value read, print the average.

awk '{ sum += $2 } END { if (NR > 0) print sum / NR }'

If you want to use the shebang notation, you could write:

#!/bin/awk

{ sum += $2 }
END { if (NR > 0) print sum / NR }

You can also control the format of the average with printf() and a suitable format ("%13.6e\n", for example).

You can also generalize the code to average the Nth column (with N=2 in this sample) using:

awk -v N=2 '{ sum += $N } END { if (NR > 0) print sum / NR }'

You just copy the cv2.pyd file to the C:\Users\USERNAME\Anaconda2\Lib directory.

{{ num_str - 0 }}

...works for me.

function getCheckedValue(radioObj, name) {

    for (j = 0; j < radioObj.rows.length; ++j) {
        for (k = 0; k < radioObj.cells.length; ++k) {
            var radioChoice = document.getElementById(name + "_" + k);
            if (radioChoice.checked) {
                return radioChoice.value;
            }
        }
    }
    return "";
}

You can use filter too

this.products = array_products.filter((x) => x.Name.includes("ABC"))

Here's a way that allows for ties for the cut-off score.

author_count = Author.objects.count()
cut_off_score = Author.objects.order_by('-score').values_list('score')[min(30, author_count)]
top_authors = Author.objects.filter(score__gte=cut_off_score).order_by('last_name')

You may get more than 30 authors in top_authors this way and the min(30,author_count) is there incase you have fewer than 30 authors.

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

I was just looking for the same thing and I realized that, once again, my thinking is different because I am old school. I go all the way back to BASIC and PERL and sometimes I forget how easy things really are in PHP.

I just made this function to take all settings from the database where their are 3 columns. setkey, item (key) & value (value) and place them into an array called settings using the same key/value without using push just like above.

Pretty easy & simple really

// Get All Settings
$settings=getGlobalSettings();


// Apply User Theme Choice
$theme_choice = $settings['theme'];

.. etc etc etc ....




function getGlobalSettings(){

    $dbc = mysqli_connect(wds_db_host, wds_db_user, wds_db_pass) or die("MySQL Error: " . mysqli_error());
    mysqli_select_db($dbc, wds_db_name) or die("MySQL Error: " . mysqli_error());
    $MySQL = "SELECT * FROM systemSettings";
    $result = mysqli_query($dbc, $MySQL);
    while($row = mysqli_fetch_array($result)) 
        {
        $settings[$row['item']] = $row['value'];   // NO NEED FOR PUSH
        }
    mysqli_close($dbc);
return $settings;
}

So like the other posts explain... In php there is no need to "PUSH" an array when you are using

Key => Value

AND... There is no need to define the array first either.

$array=array();

Don't need to define or push. Just assign $array[$key] = $value; It is automatically a push and a declaration at the same time.

I must add that for security reasons, (P)oor (H)elpless (P)rotection, I means Programming for Dummies, I mean PHP.... hehehe I suggest that you only use this concept for what I intended. Any other method could be a security risk. There, made my disclaimer!

You can try the following one-statement:

if (($x-$min)*($x-$max) < 0)

or:

if (max(min($x, $max), $min) == $x)

You can write this

class Human {
    private firstName : string;
    private lastName : string;

    constructor (
        public FirstName?:string, 
        public LastName?:string) {

    }

    get FirstName() : string {
        console.log("Get FirstName : ", this.firstName);
        return this.firstName;
    }
    set FirstName(value : string) {
        console.log("Set FirstName : ", value);
        this.firstName = value;
    } 

    get LastName() : string {
        console.log("Get LastName : ", this.lastName);
        return this.lastName;
    }
    set LastName(value : string) {
        console.log("Set LastName : ", value);
        this.lastName = value;
    } 

}

Another option is to use the package require-dir which let's you do the following. It supports recursion as well.

var requireDir = require('require-dir');
var dir = requireDir('./path/to/dir');

I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.

if you are using ps, you can check the manual

man ps

there is a list of keywords allowing you to build what you need. for example to show, userid / processid / percent cpu / percent memory / work queue / command :

ps -e -o "uid pid pcpu pmem wq comm"

-e is similar to -A (all inclusive; your processes and others), and -o is to force a format.

if you are looking for a specific uid, you can chain it using awk or grep such as :

ps -e -o "uid pid pcpu pmem wq comm" | grep 501

this should (almost) show only for userid 501. try it.

What do you want? Speed or simplicity? For speed, go for a loop based approach. For simplicity, go for a one liner RegEx based approach.

Speed

public boolean isAlpha(String name) {
    char[] chars = name.toCharArray();

    for (char c : chars) {
        if(!Character.isLetter(c)) {
            return false;
        }
    }

    return true;
}

Simplicity

public boolean isAlpha(String name) {
    return name.matches("[a-zA-Z]+");
}
