This example of a Javascript function is called by an event listener to identify the form

function submitUpdate(event) {
    trigger_field = document.getElementById(event.target.id);
    trigger_form = trigger_field.form;

Open res -> values -> styles.xml and to your <style> add this line replacing with your image path <item name="android:windowBackground">@drawable/background</item>. Example:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@drawable/background</item>
    </style>

</resources>

There is a <item name ="android:colorBackground">@color/black</item> also, that will affect not only your main window background but all the component in your app. Read about customize theme here.

If you want version specific styles:

If a new version of Android adds theme attributes that you want to use, you can add them to your theme while still being compatible with old versions. All you need is another styles.xml file saved in a values directory that includes the resource version qualifier. For example:

res/values/styles.xml        # themes for all versions
res/values-v21/styles.xml    # themes for API level 21+ only

Because the styles in the values/styles.xml file are available for all versions, your themes in values-v21/styles.xml can inherit them. As such, you can avoid duplicating styles by beginning with a "base" theme and then extending it in your version-specific styles.

Read more here(doc in theme).

If you have control over class loading, you can do static initializing from there.

Example:

class MyClass { public static function static_init() { } }

in your class loader, do the following:

include($path . $klass . PHP_EXT);
if(method_exists($klass, 'static_init')) { $klass::staticInit() }

A more heavy weight solution would be to use an interface with ReflectionClass:

interface StaticInit { public static function staticInit() { } }
class MyClass implements StaticInit { public static function staticInit() { } }

in your class loader, do the following:

$rc = new ReflectionClass($klass);
if(in_array('StaticInit', $rc->getInterfaceNames())) { $klass::staticInit() }

...any reason why you can't use min()?

def above(my_list, minimum):
    if min(my_list) >= minimum:
        print "All values are equal or above", minimum
    else:
        print "Not all values are equal or above", minimum

I don't know if this is exactly what you want, but technically, this is what you asked for...

Function ExtSql(ByVal sql As String) As Boolean
    Dim cnn As SqlConnection
    Dim cmd As SqlCommand
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        cmd = New SqlCommand
        cmd.Connection = cnn
        cmd.CommandType = CommandType.Text
        cmd.CommandText = sql
        cmd.ExecuteNonQuery()
        cnn.Close()
        cmd.Dispose()
    Catch ex As Exception
        cnn.Close()
        Return False
    End Try
    Return True
End Function

You're only adding the File object to the JSON object. The File object only contains meta information about the file: Path, name and so on.

You must load the image and read the bytes from it. Then put these bytes into the JSON object.

Port Access

Firewalls and other security tools may prevent RabbitMQ from binding to a port. When that happens, RabbitMQ will fail to start. Make sure the following ports can be opened:

4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools

5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS

25672: used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). See networking guide for details.

15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)

61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)

1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled

15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)

15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)

You only need to force cscript instead wscript. I always use this template. The function ForceConsole() will execute your vbs into cscript, also you have nice alias to print and scan text.

 Set oWSH = CreateObject("WScript.Shell")
 vbsInterpreter = "cscript.exe"

 Call ForceConsole()

 Function printf(txt)
    WScript.StdOut.WriteLine txt
 End Function

 Function printl(txt)
    WScript.StdOut.Write txt
 End Function

 Function scanf()
    scanf = LCase(WScript.StdIn.ReadLine)
 End Function

 Function wait(n)
    WScript.Sleep Int(n * 1000)
 End Function

 Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) & WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

 Function cls()
    For i = 1 To 50
        printf ""
    Next
 End Function

 printf " _____ _ _           _____         _    _____         _     _   "
 printf "|  _  |_| |_ ___ ___|     |_ _ _ _| |  |   __|___ ___|_|___| |_ "
 printf "|     | | '_| . |   |   --| | | | . |  |__   |  _|  _| | . |  _|"
 printf "|__|__|_|_,_|___|_|_|_____|_____|___|  |_____|___|_| |_|  _|_|  "
 printf "                                                       |_|     v1.0"
 printl " Enter your name:"
 MyVar = scanf
 cls
 printf "Your name is: " & MyVar
 wait(5)

You could do this:

for idx, item in enumerate(list):
   if 'foo' in item:
       item = replace_all(...)
       list[idx] = item

Something like this?

$(menu).css("top", targetE1.y + "px"); 
$(menu).css("left", targetE1.x - widthOfMenu + "px");

Use window.open():

<a onclick="window.open(document.URL, '_blank', 'location=yes,height=570,width=520,scrollbars=yes,status=yes');">
  Share Page
</a>

This will create a link titled Share Page which opens the current url in a new window with a height of 570 and width of 520.

If a class does not explicitly define a private static final long serialVersionUID in the code it will be autogenerated, and there is no guarantee that different machines will generate the same id; it looks like that is exactly what happened. Also if the classes are different in any way (using different versions of the class) the autogenerated serialVersionUIDs will also be different.

From the Serializable interface's docs:

If a serializable class does not explicitly declare a serialVersionUID, then the serialization runtime will calculate a default serialVersionUID value for that class based on various aspects of the class, as described in the Java(TM) Object Serialization Specification. However, it is strongly recommended that all serializable classes explicitly declare serialVersionUID values, since the default serialVersionUID computation is highly sensitive to class details that may vary depending on compiler implementations, and can thus result in unexpected InvalidClassExceptions during deserialization. Therefore, to guarantee a consistent serialVersionUID value across different java compiler implementations, a serializable class must declare an explicit serialVersionUID value. It is also strongly advised that explicit serialVersionUID declarations use the private modifier where possible, since such declarations apply only to the immediately declaring class--serialVersionUID fields are not useful as inherited members. Array classes cannot declare an explicit serialVersionUID, so they always have the default computed value, but the requirement for matching serialVersionUID values is waived for array classes.

You should define a serialVersionUID in the class definition, e.g.:

class MyClass implements Serializable {
    private static final long serialVersionUID = 6529685098267757690L;
    ...

You have to use image

.listStyle {
    list-style: none;
    background: url(bullet.jpg) no-repeat left center;
    padding-left: 40px;
}

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

Solved the problem by dropping the jar into WEB_INF/lib.

Session_unset(); only destroys the session variables. To end the session there is another function called session_destroy(); which also destroys the session .

update :

In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the session id (default behavior), then the session cookie must be deleted. setcookie() may be used for that

another option is to define Scanner input = new Scanner(System.in); inside the try block, this will create a new object each time you need to re-enter the values.

Consider a right angled triangle. We label the hypotenuse r, the horizontal side y and the vertical side x. The angle of interest α is the angle between x and r.

C++ atan2(y, x) will give us the value of angle α in radians. atan is used if we only know or are interested in y/x not y and x individually. So if p = y/x then to get α we'd use atan(p).

You cannot use atan2 to determine the quadrant, you can use atan2 only if you already know which quadrant your in! In particular positive x and y imply the first quadrant, positive y and negative x, the second and so on. atan or atan2 themselves simply return a positive or a negative number, nothing more.

It's simple Use following pseudo code

from pylab import imread,subplot,imshow,show

import matplotlib.pyplot as plt

image = imread('...')  // choose image location

plt.imshow(image)

plt.show() // this will show you the image on console.

You can use schemas in Access.

Sub ListAccessTables2(strDBPath)
   Dim cnnDB As ADODB.Connection
   Dim rstList As ADODB.Recordset

   Set cnnDB = New ADODB.Connection

   ' Open the connection.
   With cnnDB
      .Provider = "Microsoft.Jet.OLEDB.4.0"
      .Open strDBPath
   End With

   ' Open the tables schema rowset.
   Set rstList = cnnDB.OpenSchema(adSchemaTables)

   ' Loop through the results and print the
   ' names and types in the Immediate pane.
   With rstList
      Do While Not .EOF
         If .Fields("TABLE_TYPE") <> "VIEW" Then
            Debug.Print .Fields("TABLE_NAME") & vbTab & _
               .Fields("TABLE_TYPE")
         End If
         .MoveNext
      Loop
   End With
   cnnDB.Close
   Set cnnDB = Nothing
End Sub

SELECT u.*, p.*
FROM users AS u
INNER JOIN payments AS p ON p.id = (
    SELECT id
    FROM payments AS p2
    WHERE p2.user_id = u.id
    ORDER BY date DESC
    LIMIT 1
)

Or

SELECT u.*, p.*
FROM users AS u
INNER JOIN payments AS p ON p.user_id = u.id
WHERE NOT EXISTS (
    SELECT 1
    FROM payments AS p2
    WHERE
        p2.user_id = p.user_id AND
        (p2.date > p.date OR (p2.date = p.date AND p2.id > p.id))
)

This solutions are better than the accepted answer because they work correctly when there are multiple payments with same user and date. You can try on SQL Fiddle.

You can call java myProg arg1 arg2 ... :

public static void main (String args[]) {
    BufferedReader in = new BufferedReader(new FileReader(args[0]));
}

This code works for me to call the parent_fragment method from child_fragment.

ParentFragment parent = (ParentFragment) activity.getFragmentManager().findViewById(R.id.contaniner);

parent.callMethod();

AJAX requests are asynchronous. Your doSomething function is being exectued, the AJAX request is being made but it happens asynchronously; so the remainder of doSomething is executed and the value of status is undefined when it is returned.

Effectively, your code works as follows:

function doSomething(someargums) {
     return status;
}

var response = doSomething();

And then some time later, your AJAX request is completing; but it's already too late

You need to alter your code, and populate the "response" variable in the "success" callback of your AJAX request. You're going to have to delay using the response until the AJAX call has completed.

Where you previously may have had

var response = doSomething();

alert(response);

You should do:

function doSomething() {  
    $.ajax({
           url:'action.php',
           type: "POST",
           data: dataString,
           success: function (txtBack) { 
            alert(txtBack);
           })
    }); 
};

You can also use exists, since sometimes it's faster than left join. You'd have to benchmark them to figure out which one you want to use.

select
    id
from
    tableA a
where
    not exists
    (select 1 from tableB b where b.id = a.id)

To show that exists can be more efficient than a left join, here's the execution plans of these queries in SQL Server 2008:

left join - total subtree cost: 1.09724:

exists - total subtree cost: 1.07421:

After i tried Android official Autosizing TextView, i found if your Android version is prior to Android 8.0 (API level 26), you need use android.support.v7.widget.AppCompatTextView, and make sure your support library version is above 26.0.0. Example:

<android.support.v7.widget.AppCompatTextView
    android:layout_width="130dp"
    android:layout_height="32dp"
    android:maxLines="1"
    app:autoSizeMaxTextSize="22sp"
    app:autoSizeMinTextSize="12sp"
    app:autoSizeStepGranularity="2sp"
    app:autoSizeTextType="uniform" />

update:

According to @android-developer's reply, i check the AppCompatActivity source code, and found these two lines in onCreate

final AppCompatDelegate delegate = getDelegate(); delegate.installViewFactory();

and in AppCompatDelegateImpl's createView

    if (mAppCompatViewInflater == null) {
        mAppCompatViewInflater = new AppCompatViewInflater();
    }

it use AppCompatViewInflater inflater view, when AppCompatViewInflater createView it will use AppCompatTextView for "TextView".

public final View createView(){
    ...
    View view = null;
    switch (name) {
        case "TextView":
            view = new AppCompatTextView(context, attrs);
            break;
        case "ImageView":
            view = new AppCompatImageView(context, attrs);
            break;
        case "Button":
            view = new AppCompatButton(context, attrs);
            break;
    ...
}

In my project i don't use AppCompatActivity, so i need use <android.support.v7.widget.AppCompatTextView> in xml.

Since Java arrays hold a fixed number of values, you need to create a new array with a length of 5 in this case. A better solution would be to use an ArrayList and simply add strings to the array.

Example:

ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test3");
scripts.add("test4");
scripts.add("test5");

// Then later you can add more Strings to the ArrayList
scripts.add("test1");
scripts.add("test2");

If you have constant URL I recommend use simplified http-request built on apache http.

You can build your client as following:

private filan static HttpRequest<YourResponseType> httpRequest = 
                   HttpRequestBuilder.createGet(yourUri,YourResponseType)
                   .build();

public void send(){
    ResponseHendler<YourResponseType> rh = 
         httpRequest.execute(param1, value1, param2, value2);

    handler.ifSuccess(this::whenSuccess).otherwise(this::whenNotSuccess);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
     rh.ifHasContent(content -> // your code);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
   LOGGER.error("Status code: " + rh.getStatusCode() + ", Error msg: " + rh.getErrorText());
}

Note: There are many useful methods to manipulate your response.

Another option is to let tkinter execute on a separate thread. One way of doing it is like this:

import Tkinter
import threading

class MyTkApp(threading.Thread):
    def __init__(self):
        self.root=Tkinter.Tk()
        self.s = Tkinter.StringVar()
        self.s.set('Foo')
        l = Tkinter.Label(self.root,textvariable=self.s)
        l.pack()
        threading.Thread.__init__(self)

    def run(self):
        self.root.mainloop()


app = MyTkApp()
app.start()

# Now the app should be running and the value shown on the label
# can be changed by changing the member variable s.
# Like this:
# app.s.set('Bar')

Be careful though, multithreaded programming is hard and it is really easy to shoot your self in the foot. For example you have to be careful when you change member variables of the sample class above so you don't interrupt with the event loop of Tkinter.

You can make use of the React.createClone method. Create your element, than create a clone of it. During the clone's creation, you can inject props. Inject an onClick : method prop like this

{ onClick : () => this.changeColor(originalElement, index) }

the changeColor method will set the state with the duplicate, allowing you sto set the color in the process.

render()_x000D_
  {_x000D_
    return(_x000D_
      <ul>_x000D_

          let item = <li key={ind}>{val}</li>;_x000D_
          let props = { _x000D_
            onClick: () => this.Click(item, ind),_x000D_
            key : ind,_x000D_
            ind_x000D_
          }_x000D_
          let clone = React.cloneElement(item, props, [val]);_x000D_
          return clone;_x000D_
        })}_x000D_
_x000D_
      </ul>_x000D_

You are copying all files to a single file called TEST_BACKUP_FOLDER

try this:

md TEST_BACKUP_FOLDER
copy "\\My_Servers_IP\Shared Drive\FolderName\*" TEST_BACKUP_FOLDER

Sub Button167_Click()
 If ThisWorkbook.Worksheets(1).Shapes("Check Box 1").OLEFormat.Object.Value = 1 Then
 Range("Y12").Value = 1
 Else
 Range("Y12").Value = 0
 End If
End Sub

1 is checked, -4146 is unchecked, 2 is mixed (grey box)

After a lot of research, I was able to come up with this. This has more special characters

validatePassword(password) {
        const re = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$%^&*()+=-\?;,./{}|\":<>\[\]\\\' ~_]).{8,}/
        return re.test(password);
    }

In simple words.

In Python you should add self argument as the first argument to all defined methods in classes:

class MyClass:
  def method(self, arg):
    print(arg)

Then you can use your method according to your intuition:

>>> my_object = MyClass()
>>> my_object.method("foo")
foo

This should solve your problem :)

For a better understanding, you can also read the answers to this question: What is the purpose of self?

You could create a list of Object like List<Object> list = new ArrayList<Object>(). As all classes implementation extends implicit or explicit from java.lang.Object class, this list can hold any object, including instances of Employee, Integer, String etc.

When you retrieve an element from this list, you will be retrieving an Object and no longer an Employee, meaning you need to perform a explicit cast in this case as follows:

List<Object> list = new ArrayList<Object>();
list.add("String");
list.add(Integer.valueOf(1));
list.add(new Employee());

Object retrievedObject = list.get(2);
Employee employee = (Employee)list.get(2); // explicit cast

$("**:**input[type=text], :input[type='textarea']").css({width: '90%'});

The way I do it is to do a Topological Sort, counting the number of vertices visited. If that number is less than the total number of vertices in the DAG, you have a cycle.

Try to see if the following code helps you:

Dim iDate As String = "05/05/2005"
Dim oDate As DateTime = Convert.ToDateTime(iDate)

According to the jQuery official documentation

To create a HTML element, $("<div/>") or $("<div></div>") is preferred.

Then you can use either appendTo, append, before, after and etc,. to insert the new element to the DOM.

PS: jQuery Version 1.11.x

You can set a primary key on a text column. In phpMyAdmin, display the Structure of your table, click on Indexes, then ask to create the index on one column. Then choose PRIMARY, pick your TEXT column, but you have to put a length big enough so that its unique.

After reading many questions on stackoverflow I found out that my CPU does not support Virtualization. I have to upgrade to the cpu which supports Virtualization in order to install Intel X 86 Emulator accelerator(Haxm Installer)

They are different things. The Forms Authentication Timeout value sets the amount of time in minutes that the authentication cookie is set to be valid, meaning, that after value number of minutes, the cookie will expire and the user will no longer be authenticated—they will be redirected to the login page automatically. The slidingExpiration=true value is basically saying that as long as the user makes a request within the timeout value, they will continue to be authenticated (more details here). If you set slidingExpiration=false the authentication cookie will expire after value number of minutes regardless of whether the user makes a request within the timeout value or not.

The SessionState timeout value sets the amount of time a Session State provider is required to hold data in memory (or whatever backing store is being used, SQL Server, OutOfProc, etc) for a particular session. For example, if you put an object in Session using the value in your example, this data will be removed after 30 minutes. The user may still be authenticated but the data in the Session may no longer be present. The Session Timeout value is always reset after every request.

Komodo is wonderful, and it runs on OS X; they have a free version, Komodo Edit.

UPDATE from 2015: I've switched to PHPStorm from Jetbrains, the same folks that built IntelliJ IDEA and Resharper. It's better. Not just better. It's well worth the money.

This can get more complicated depending on where PHP sits in your environment, since your question is quite broad. This may depend on whether there's a load-balancer and how it's configured. Here are are a few related questions:

• How can I prevent access to PHP files if the caller isn't using HTTPS?
• Detecting HTTPS vs HTTP on server sending back nothing useful

Scrolling to the bottom of a page:

JavascriptExecutor js = ((JavascriptExecutor) driver);
js.executeScript("window.scrollTo(0, document.body.scrollHeight)");

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

Suprisingly nobody came up with the idea of just using a div with paddingyet, so here you go:

<div style="padding-left: 30px;">
My text
</div>

If you use JSON.NET with old version which didn't JObject.

This is another simple way to make a dynamic object from JSON: https://github.com/chsword/jdynamic

NuGet Install

PM> Install-Package JDynamic

Support using string index to access member like:

dynamic json = new JDynamic("{a:{a:1}}");
Assert.AreEqual(1, json["a"]["a"]);

Test Case

And you can use this util as following :

Get the value directly

dynamic json = new JDynamic("1");

//json.Value

2.Get the member in the json object

dynamic json = new JDynamic("{a:'abc'}");
//json.a is a string "abc"

dynamic json = new JDynamic("{a:3.1416}");
//json.a is 3.1416m

dynamic json = new JDynamic("{a:1}");
//json.a is integer: 1

3.IEnumerable

dynamic json = new JDynamic("[1,2,3]");
/json.Length/json.Count is 3
//And you can use json[0]/ json[2] to get the elements

dynamic json = new JDynamic("{a:[1,2,3]}");
//json.a.Length /json.a.Count is 3.
//And you can use  json.a[0]/ json.a[2] to get the elements

dynamic json = new JDynamic("[{b:1},{c:1}]");
//json.Length/json.Count is 2.
//And you can use the  json[0].b/json[1].c to get the num.

Other

dynamic json = new JDynamic("{a:{a:1} }");

//json.a.a is 1.

How about this?

fmt.Printf("%c","HELLO"[1])

As Peter points out, to allow for more than just ASCII:

fmt.Printf("%c", []rune("HELLO")[1])

I assume you want to know the performance difference between the following:

WHERE foo IN ('a', 'b', 'c')
WHERE foo = 'a' OR foo = 'b' OR foo = 'c'

According to the manual for MySQL if the values are constant IN sorts the list and then uses a binary search. I would imagine that OR evaluates them one by one in no particular order. So IN is faster in some circumstances.

The best way to know is to profile both on your database with your specific data to see which is faster.

I tried both on a MySQL with 1000000 rows. When the column is indexed there is no discernable difference in performance - both are nearly instant. When the column is not indexed I got these results:

SELECT COUNT(*) FROM t_inner WHERE val IN (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000);
1 row fetched in 0.0032 (1.2679 seconds)

SELECT COUNT(*) FROM t_inner WHERE val = 1000 OR val = 2000 OR val = 3000 OR val = 4000 OR val = 5000 OR val = 6000 OR val = 7000 OR val = 8000 OR val = 9000;
1 row fetched in 0.0026 (1.7385 seconds)

So in this case the method using OR is about 30% slower. Adding more terms makes the difference larger. Results may vary on other databases and on other data.

find -type f -print0 | xargs -0 ls -t

Drawback: Works only to a certain amount of files. If you have extremly large amounts of files you need something more complicated

you can use equals() method to statisfy your demands. == in java programming language has a different meaning!

In my solution, i have

$scope.uploadVideo = function(){
    var uploadUrl = "/api/uploadEvent";


    //obj with data, that can be one input or form
    file = $scope.video;
    var fd = new FormData();


    //check file form on being
    for (var obj in file) {
        if (file[obj] || file[obj] == 0) {
            fd.append(obj, file[obj]);
        }
    }

    //open XHR request
    var xhr = new XMLHttpRequest();


    // $apply to rendering progress bar for any chunking update
    xhr.upload.onprogress = function(event) {
        $scope.uploadStatus = {
            loaded: event.loaded,
            total:  event.total
        };
        $scope.$apply();
    };

    xhr.onload = xhr.onerror = function(e) {
        if (this.status == 200 || this.status == 201) {

            //sucess

            $scope.uploadStatus = {
                loaded: 0,
                total:  0
            };


            //this is for my solution
            $scope.video = {};
            $scope.vm.model.push(JSON.parse(e.currentTarget.response));
            $scope.$apply();

        } else {
           //on else status
        }
    };

    xhr.open("POST", uploadUrl, true);

    //token for upload, thit for my solution
    xhr.setRequestHeader("Authorization", "JWT " + window.localStorage.token);


    //send
    xhr.send(fd); 
};

}

How about this:

def singleton(cls):
    instance=cls()
    cls.__new__ = cls.__call__= lambda cls: instance
    cls.__init__ = lambda self: None
    return instance

Use it as a decorator on a class that should be a singleton. Like this:

@singleton
class MySingleton:
    #....

This is similar to the singleton = lambda c: c() decorator in another answer. Like the other solution, the only instance has name of the class (MySingleton). However, with this solution you can still "create" instances (actually get the only instance) from the class, by doing MySingleton(). It also prevents you from creating additional instances by doing type(MySingleton)() (that also returns the same instance).

I updated the answer of @Stichoza to remove files through subfolders.

function glob_recursive($pattern, $flags = 0) {
    $fileList = glob($pattern, $flags);
    foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
        $subPattern = $dir.'/'.basename($pattern);
        $subFileList = glob_recursive($subPattern, $flags);
        $fileList = array_merge($fileList, $subFileList);
    }
    return $fileList;
}

function glob_recursive_unlink($pattern, $flags = 0) {
    array_map('unlink', glob_recursive($pattern, $flags));
}

If your code should work in both Python 2 and 3, you can achieve this by loading this at the beginning of your program:

from __future__ import print_function   # If code has to work in Python 2 and 3!

Then you can print in the Python 3 way:

print("python")

If you want to print something without creating a new line - you can do this:

for number in range(0, 10):
    print(number, end=', ')

Try this:

$str = '123456789';
$char_array = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);

You have explicitly set your stroke-linejoin to round but your stroke-width to 0, so of course you're not going to see rounded corners if you have no stroke to round.

Here's a modified example with rounded corners made through strokes:
http://jsfiddle.net/8uxqK/1/

<path d="M64.5 45.5 82.5 45.5 82.5 64.5 64.5 64.5 z"
      stroke-width="5"
      stroke-linejoin="round"
      stroke="#808600"
      fill="#a0a700" />

Otherwise—if you need an actual rounded shape fill and not just a rounded fatty stroke—you must do what @Jlange says and make an actual rounded shape.

You can get the maximum like this:

>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]]
   A  B
0  1 -2
1  2  8
2  3  1
>>> df[["A", "B"]].max(axis=1)
0    1
1    8
2    3

and so:

>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

If you know that "A" and "B" are the only columns, you could even get away with

>>> df["C"] = df.max(axis=1)

And you could use .apply(max, axis=1) too, I guess.

I'm forced to post this as an answer instead of a comment due to low reputation. I had a similar problem to Matteo. The difference being that I had no map from my first x-axis to my second x-axis, only the x-values themselves. So I wanted to set the data on my second x-axis directly, not the ticks, however, there is no axes.set_xdata. I was able to use Dhara's answer to do this with a modification:

ax2.lines = []

instead of using:

ax2.cla()

When in use also cleared my plot from ax1.

I think the answers are below

List<string> aa = (from char c in source
                    select c.ToString() ).ToList();

List<string> aa2 = (from char c1 in source
                    from char c2 in source
                    select string.Concat(c1, ".", c2)).ToList();

The main difference between RPC and RMI is that RMI involves objects. Instead of calling procedures remotely by use of a proxy function, we instead use a proxy object.

There is greater transparency with RMI, namely due the exploitation of objects, references, inheritance, polymorphism, and exceptions as the technology is integrated into the language.

RMI is also more advanced than RPC, allowing for dynamic invocation, where interfaces can change at runtime, and object adaption, which provides an additional layer of abstraction.

The AutoPostBack property is used to set or return whether or not an automatic postback occurs when the user presses "ENTER" or "TAB" in the TextBox control.

If this property is set to TRUE the automatic postback is enabled, otherwise FALSE. The default is FALSE.

There are two ways:

1. Use the axes methods of the subplot object (e.g. ax.set_xticks and ax.set_xticklabels) or
2. Use plt.sca to set the current axes for the pyplot state machine (i.e. the plt interface).

As an example (this also illustrates using setp to change the properties of all of the subplots):

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=3, ncols=4)

# Set the ticks and ticklabels for all axes
plt.setp(axes, xticks=[0.1, 0.5, 0.9], xticklabels=['a', 'b', 'c'],
        yticks=[1, 2, 3])

# Use the pyplot interface to change just one subplot...
plt.sca(axes[1, 1])
plt.xticks(range(3), ['A', 'Big', 'Cat'], color='red')

fig.tight_layout()
plt.show()

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

Running Eclipse Luna and using WifiADB app on my phone I started getting this error when Running my app from Eclipse. Oddly, in Indigo (I installed Luna last night) it was working fine.

The problem for me was I had the phone connected to the PC to charge it, and even when running a .bat script to kill ADB it appeared that a second instance was started when Run. Plugging the phone into the monitor to charge when debugging over wifi solved it. I need to debug on wifi sometimes to test my app stopping/starting on power state change.

Of course it reasonable to assume (highly likely) I've just not set Luna up the same.

If your system has python2 as default, use below command to install packages to python3

$ python3 -m pip install <package-name>

I am summarizing the steps that helped me in resolving this issue:

1. Make sure the SSL port range(used by IIS express) is between 44300-44398

During installation, IIS Express uses Http.sys to reserve ports 44300 through 44399 for SSL use. This enables standard users (without elevated privileges) of IISExpress to configure and use SSL. For more details on this refer here

2. Run the below command as administrator in Command prompt. This will output the SSL Certificate bindings in the computer. From this list, find out the certificate used by IIS express for the corresponding port :

netsh http show sslcert > sslcert.txt

3. Look for the below items in the sslcert.txt (in my case the IIS express was running at port 44300)

IP:port : 0.0.0.0:44300

Certificate Hash : eb380ba6bd10fb4f597cXXXXXXXXXX

Application ID : {214124cd-d05b-4309-XXX-XXXXXXX}

4. Also look in the IIS express management console (RUN (Ctrl+R) -> inetmgr.exe) and find if the corresponding certificate exists in the Server Certificates

(Click on the ServerRoot -> under section IIS () -> Open the Server Certificates)

5. If your localhost by default uses a different certificate other than the one listed in Step 3, continue with the below steps

netsh http delete sslcert ipport=0.0.0.0:44300

netsh http add sslcert ipport=0.0.0.0:44300 certhash=New_Certificate_Hash_without_space appid={214124cd-d05b-4309-XXX-XXXXXXX}

The New_Certificate_Hash will be your default certificate tied-up with your localhost (That we found in step 4) or the one which you want to add as a new certificate.

P.S. Thank you for your answer uos?? (which helped me in resolving this issue)

What about

Form1.textBox1.text = "change text";

note: 1. you have to "include" Form1 to your second form source file by using Form1;

1. textBox1 should be public

This solution is better because it is shorter and doesn't use a loop.

id="checkAll" is the header column

$('#checkAll').on('click', function() {
        if (this.checked == true)
            $('#userTable').find('input[name="checkboxRow"]').prop('checked', true);
        else
            $('#userTable').find('input[name="checkboxRow"]').prop('checked', false);
    });

I think the following link will help you. If you want to generate fields dynamically and also want to remove them on the same time you can get the help from here. I had the same question, So i got the answer

$(function() {
        var scntDiv = $('#p_scents');
        var i = $('#p_scents p').size() + 1;

        $('#addScnt').live('click', function() {
                $('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" name="p_scnt_' + i +'" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv);
                i++;
                return false;
        });

        $('#remScnt').live('click', function() { 
                if( i > 2  ) {
                        $(this).parents('p').remove();
                        i--;
                }
                return false;

Why do I need the descriptor class?

Inspired by Fluent Python by Buciano Ramalho

Imaging you have a class like this

class LineItem:
     price = 10.9
     weight = 2.1
     def __init__(self, name, price, weight):
          self.name = name
          self.price = price
          self.weight = weight

item = LineItem("apple", 2.9, 2.1)
item.price = -0.9  # it's price is negative, you need to refund to your customer even you delivered the apple :(
item.weight = -0.8 # negative weight, it doesn't make sense

We should validate the weight and price in avoid to assign them a negative number, we can write less code if we use descriptor as a proxy as this

class Quantity(object):
    __index = 0

    def __init__(self):
        self.__index = self.__class__.__index
        self._storage_name = "quantity#{}".format(self.__index)
        self.__class__.__index += 1

    def __set__(self, instance, value):
        if value > 0:
            setattr(instance, self._storage_name, value)
        else:
           raise ValueError('value should >0')

   def __get__(self, instance, owner):
        return getattr(instance, self._storage_name)

then define class LineItem like this:

class LineItem(object):
     weight = Quantity()
     price = Quantity()

     def __init__(self, name, weight, price):
         self.name = name
         self.weight = weight
         self.price = price

and we can extend the Quantity class to do more common validating

I was facing the same issues since several days, Today i have found the solution. I have shown the complete file which is ready to execute.

If you are running the app on an emulator, make sure that it is properly connected to the internet. If it is not, the easiest way of solving it is reopening the emulator or creating a new device.

This is one of the popular question in any SQL interview. I am going to write down different queries to find out the nth highest value of a column.

I have created a table named “Emloyee” by running the below script.

CREATE TABLE Employee([Eid] [float] NULL,[Ename] [nvarchar](255) NULL,[Basic_Sal] [float] NULL)

Now I am going to insert 8 rows into this table by running below insert statement.

insert into Employee values(1,'Neeraj',45000)
insert into Employee values(2,'Ankit',5000)
insert into Employee values(3,'Akshay',6000)
insert into Employee values(4,'Ramesh',7600)
insert into Employee values(5,'Vikas',4000)
insert into Employee values(7,'Neha',8500)
insert into Employee values(8,'Shivika',4500)
insert into Employee values(9,'Tarun',9500)

Now we will find out 3rd highest Basic_sal from the above table using different queries. I have run the below query in management studio and below is the result.

select * from Employee order by Basic_Sal desc

We can see in the above image that 3rd highest Basic Salary would be 8500. I am writing 3 different ways of doing the same. By running all three mentioned below queries we will get same result i.e. 8500.

First Way: - Using row number function

select Ename,Basic_sal
from(
            select Ename,Basic_Sal,ROW_NUMBER() over (order by Basic_Sal desc) as rowid from Employee
      )A
where rowid=2

Casting never needs a new:

Collection<T> collection = myList;

You don't even make the cast explicit, because Collection is a super-type of List, so it will work just like this.

You can use:

getResources().getColor(R.color.idname);

Check here on how to define custom colors:

http://sree.cc/google/android/defining-custom-colors-using-xml-in-android

EDIT(1): Since getColor(int id) is deprecated now, this must be used :

ContextCompat.getColor(context, R.color.your_color);

(added in support library 23)

EDIT(2):

Below code can be used for both pre and post Marshmallow (API 23)

ResourcesCompat.getColor(getResources(), R.color.your_color, null); //without theme

ResourcesCompat.getColor(getResources(), R.color.your_color, your_theme); //with theme

First Method

when you want to open a video in full screen for that Activity you have to set the theme attribute in the Manifest. set this value that is

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

change theme programmatically here

Second Method

create another fullscreen.xml like below and setContentView(R.layout.fullscreen) on click of the button

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <VideoView android:id="@+id/myvideoview"
        android:layout_width="fill_parent"
        android:layout_alignParentRight="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

have a look at mysql_insert_id()

here the documentation: http://in.php.net/manual/en/function.mysql-insert-id.php

dtAll = dtOne.Copy();
dtAll.Merge(dtTwo,true);

The parameter TRUE preserve the changes.

For more details refer to MSDN.

ANTLR mega tutorial by Gabriele Tomassetti is very helpful

It has grammar examples, examples of visitors in different languages (Java, JavaScript, C# and Python) and many other things. Highly recommended.

EDIT: other useful articles by Gabriele Tomassetti on ANTLR

• Getting started with ANTLR in C#
• Getting Started with ANTLR in C++

Here is an updated method with syntax that is more common in python code. It also prevents you from opening the same file multiple times.

import pandas as pd

sheet1, sheet2 = None, None
with pd.ExcelFile("PATH\FileName.xlsx") as reader:
    sheet1 = pd.read_excel(reader, sheet_name='Sheet1')
    sheet2 = pd.read_excel(reader, sheet_name='Sheet2')

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_excel.html

There's a .val() method:

If you've got an input with an id of txtEmail you can use the following code to access the value of the text box:

$("#txtEmail").val()

You can also use the val(string) method to set that value:

$("#txtEmail").val("something")

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

If the values are integer then you can use [2-3] or you can use [5,7,8] for non continuous values.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    1)
        echo "one"
        ;;
    [2-3])
        echo "two or three"
        ;;
    [4-6])
        echo "four to six"
        ;;
    [7,9])
        echo "seven or nine"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

If the values are string then you can use |.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    "one")
        echo "one"
        ;;
    "two" | "three")
        echo "two or three"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

You could also write

-Wl,-rpath=.

To get rid of that pesky space. It's arguably more readable than adding extra commas (it's exactly what gets passed to ld).

Feb, 2016:

I needed to do this based on client entered database values and without a lat/long generator. Google really likes lat/long these days. Here is what I learned:

1 The beginning of the link looks like this: https://www.google.com/maps/place/

2 Then you put your address:

• Use a + instead of any space.
• Put a comma , in front and behind the city.
• Include the postal/zip and the province/state.
• Replace any # with nothing.
• Replace any ++ or ++++ with single +

3 Put the address after the place/

4 Then put a slash at the end.

NOTE: The slash at the end was important. After the user clicks the link, Google goes ahead and appends more to the URL and they do it after this slash.

Working example for this question:

https://www.google.ca/maps/place/1200+Pennsylvania+Ave+SE,+Washington,+DC+20003/

I hope that helps.

Jim's answer to this question may help; I copy it here. Quoting Guido van Rossum:

First of all, I chose len(x) over x.len() for HCI reasons (def __len__() came much later). There are two intertwined reasons actually, both HCI:

(a) For some operations, prefix notation just reads better than postfix — prefix (and infix!) operations have a long tradition in mathematics which likes notations where the visuals help the mathematician thinking about a problem. Compare the easy with which we rewrite a formula like x*(a+b) into xa + xb to the clumsiness of doing the same thing using a raw OO notation.

(b) When I read code that says len(x) I know that it is asking for the length of something. This tells me two things: the result is an integer, and the argument is some kind of container. To the contrary, when I read x.len(), I have to already know that x is some kind of container implementing an interface or inheriting from a class that has a standard len(). Witness the confusion we occasionally have when a class that is not implementing a mapping has a get() or keys() method, or something that isn’t a file has a write() method.

Saying the same thing in another way, I see ‘len‘ as a built-in operation. I’d hate to lose that. /…/

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

Query to achieve your requirment

SELECT id,GROUP_CONCAT(text SEPARATOR ' ') AS text FROM table_name group by id;

So here is an idea!

Since it seemed to work somewhere else.

install python-virtualenv and optionally you can install virtualenv-wrapper (which is pretty cool to create projects and so on)

In each env, you might have different versions of eggs. In other word, you could have sqlalchemy 1 and sqlaclhemy 1.5 in two different envs and they won't conflict with each others. It seems that you have a problem with your currently installed eggs.

So here we go:

virtualenv --no-site-packages foo
source foo/bin/activate

The parameter --no-site-packages will create a virtualenv and not use the packages already installed on your computer. It's pretty much like a bare python install.

source foo/bin/activate loads the virtualenv.

It's not that really userfriendly. And that's why http://www.doughellmann.com/projects/virtualenvwrapper/ exists.

That said, you should see somthing like thant in your terminal "(foo)user@domain$:" once your virtualenv is activated. It means that you can go on!

Then you have to do.

python setup.py develop of your project. It should download and install dependencies of your project in the virtualenv located in foo. If you need to install anything else, please use pip or easy_install without using sudo. When using virtualenv, you almost never need to use sudo. Sudo will install package in your global python install while it's not required and not really desirable.

If something happens in your virtualenv, you can always delete it and create a new one. This is no big deal. No need to mess with anything. Doesn't work? start over, do pip install -U if needed, define the versions if needed and so on.

Last but not least, in the other answers, it seems that the import changed. If the new versions for flask-sqlalchemy is located somewhere else, you should update your import or install the version you used to use.

I believe you are trying to do exactly what I just tried to do: I want two stacked canvases... the bottom one has a static image and the top one contains animated sprites. Because of the animation, you need to clear the background of the top layer to transparent at the start of rendering every new frame. I finally found the answer: it's not using globalAlpha, and it's not using a rgba() color. The simple, effective answer is:

context.clearRect(0,0,width,height);

A Simple Explanation:

1. Are you serializing data?

   Serialization is basically writing class data to a file/stream/etc. De-serialization is reading that data back to a class.

2. Do you intend to go into production?

   If you are just testing something with unimportant/fake data, then don't worry about it (unless you are testing serialization directly).

3. Is this the first version?

   If so, set serialVersionUID=1L.

4. Is this the second, third, etc. prod version?

   Now you need to worry about serialVersionUID, and should look into it in depth.

Basically, if you don't update the version correctly when you update a class you need to write/read, you will get an error when you try to read old data.

This works for me. Hope it will work for you too.

Short and Simple Solution

e.preventDefault();
var value = $('#id').val();
var id = $('#some_id').val();
url="{{url('office/service/requirement/rule_delete/')}}" +"/"+ id;
console.log(url);
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
$.ajax({
/* the route pointing to the post function */
    url: url,
    type: 'DELETE',
/* send the csrf-token and the input to the controller */
    data: {message:value},
    dataType: 'JSON',
/* remind that 'data' is the response of the AjaxController */
    success: function (data) { 
    console.log(data)
    //$('.writeinfo').append(data.msg);
    //$('#ruleRow'+id).remove();
    }
});
return false;

To return a value when using try/catch you can use a temporary variable, e.g.

public static double add(String[] values) {
    double sum = 0.0;
    try {
        int length = values.length;
        double arrayValues[] = new double[length];
        for(int i = 0; i < length; i++) {
            arrayValues[i] = Double.parseDouble(values[i]);
            sum += arrayValues[i];
        }
    } catch(NumberFormatException e) {
        e.printStackTrace();
    } catch(RangeException e) {
        throw e;
    } finally {
        System.out.println("Thank you for using the program!");
    }
    return sum;
}

Else you need to have a return in every execution path (try block or catch block) that has no throw.

This is the best solution ever rather than hacking CSS.

You can use this also if you want to achieve only half part of label as underline:- //For Swift 4.0+

let attributesForUnderLine: [NSAttributedString.Key: Any] = [
            .font: UIFont(name: AppFont.sourceSansPro_Regular, size: 12) ?? UIFont.systemFont(ofSize: 11),
            .foregroundColor: UIColor.blue,
            .underlineStyle: NSUnderlineStyle.single.rawValue]

        let attributesForNormalText: [NSAttributedString.Key: Any] = [
            .font: UIFont(name: AppFont.sourceSansPro_Regular, size: 12) ?? UIFont.systemFont(ofSize: 11),
            .foregroundColor: AppColors.ColorText_787878]

        let textToSet = "Want to change your preferences? Edit Now"
        let rangeOfUnderLine = (textToSet as NSString).range(of: "Edit Now")
        let rangeOfNormalText = (textToSet as NSString).range(of: "Want to change your preferences?")

        let attributedText = NSMutableAttributedString(string: textToSet)
        attributedText.addAttributes(attributesForUnderLine, range: rangeOfUnderLine)
        attributedText.addAttributes(attributesForNormalText, range: rangeOfNormalText)
        yourLabel.attributedText = attributedText

Here's another approach:

def my_func(arg1, arg2, arg3):
    ... so something ...

kwargs = {'arg1': 'Value One', 'arg2': 'Value Two', 'arg3': 'Value Three'}
# Now you can call the function with kwargs like this:

my_func(**kwargs)

Also, notice that by default Jersey will override the response body in case of an http code 400 or more.

In order to get your specified entity as the response body, try to add the following init-param to your Jersey in your web.xml configuration file :

    <init-param>
        <!-- used to overwrite default 4xx state pages -->
        <param-name>jersey.config.server.response.setStatusOverSendError</param-name>
        <param-value>true</param-value>
    </init-param>

To make it more flexible, you can design a FilterBackend as below:

class AnalyticsFilterBackend(generic_filters.BaseFilterBackend):
    def filter_queryset(self, request, queryset, view):
        predicate = request.query_params # or request.data for POST

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is not None:
            queryset = queryset.filter(your_date__range=(predicate['from_date'], predicate['to_date']))

        if predicate.get('from_date', None) is not None and predicate.get('to_date', None) is None:
            queryset = queryset.filter(your_date__gte=predicate['from_date'])

        if predicate.get('to_date', None) is not None and predicate.get('from_date', None) is None:
            queryset = queryset.filter(your_date__lte=predicate['to_date'])
        return queryset

Change

$info=$_POST['id[]'];

to

$info=$_POST['id'];

by adding [] to the end of your form field names, PHP will automatically convert these variables into arrays.

Check also that you don't have this turned on: Configuration Properties -> C/C++ -> Preprocessor -> Preprocess to a File.

I'm encountering the same problem (PHP-5.2.11/Windows). I'm using this workaround

$json = preg_replace( "/\"(\d+)\"/", '$1', $json );

which replaces all (non-negative, integer) numbers enclosed in quotes with the number itself ('"42"' becomes '42').

See also this comment in PHP manual.

CHAR(5)

or

MEDIUMINT (5) UNSIGNED ZEROFILL

The first takes 5 bytes per zip code.

The second takes only 3 bytes per zip code. The ZEROFILL option is necessary for zip codes with leading zeros.

As a careful programmer will often throw an exception for a special occurrence, it worth mentioning some general purpose exceptions like IllegalArgumentException and IllegalStateException and UnsupportedOperationException. IllegalArgumentException is my favorite:

throw new IllegalArgumentException("Word contains blank: " + word);

From the jinja docs section HTML Escaping:

When automatic escaping is enabled everything is escaped by default except for values explicitly marked as safe. Those can either be marked by the application or in the template by using the |safe filter.

Example:

 <div class="info">
   {{data.email_content|safe}}
 </div>

Yes, you can. By specifying the object_pairs_hook argument to JSONDecoder. In fact, this is the exact example given in the documentation.

>>> json.JSONDecoder(object_pairs_hook=collections.OrderedDict).decode('{"foo":1, "bar": 2}')
OrderedDict([('foo', 1), ('bar', 2)])
>>> 

You can pass this parameter to json.loads (if you don't need a Decoder instance for other purposes) like so:

>>> import json
>>> from collections import OrderedDict
>>> data = json.loads('{"foo":1, "bar": 2}', object_pairs_hook=OrderedDict)
>>> print json.dumps(data, indent=4)
{
    "foo": 1,
    "bar": 2
}
>>> 

Using json.load is done in the same way:

>>> data = json.load(open('config.json'), object_pairs_hook=OrderedDict)

class FooObservableCollection : ObservableCollection<Foo>
{
    protected override void InsertItem(int index, Foo item)
    {
        base.Add(index, Foo);

        if (this.CollectionChanged != null)
            this.CollectionChanged(this, new NotifyCollectionChangedEventArgs (NotifyCollectionChangedAction.Add, item, index);
    }
}

var collection = new FooObservableCollection();
collection.CollectionChanged += CollectionChanged;

collection.Add(new Foo());

void CollectionChanged (object sender, NotifyCollectionChangedEventArgs e)
{
    Foo newItem = e.NewItems.OfType<Foo>().First();
}

For those of you who learn by examples!

1. The purpose of * is to give you the ability to define a function that can take an arbitrary number of arguments provided as a list (e.g. f(*myList) ).
2. The purpose of ** is to give you the ability to feed a function's arguments by providing a dictionary (e.g. f(**{'x' : 1, 'y' : 2}) ).

Let us show this by defining a function that takes two normal variables x, y, and can accept more arguments as myArgs, and can accept even more arguments as myKW. Later, we will show how to feed y using myArgDict.

def f(x, y, *myArgs, **myKW):
    print("# x      = {}".format(x))
    print("# y      = {}".format(y))
    print("# myArgs = {}".format(myArgs))
    print("# myKW   = {}".format(myKW))
    print("# ----------------------------------------------------------------------")

# Define a list for demonstration purposes
myList    = ["Left", "Right", "Up", "Down"]
# Define a dictionary for demonstration purposes
myDict    = {"Wubba": "lubba", "Dub": "dub"}
# Define a dictionary to feed y
myArgDict = {'y': "Why?", 'y0': "Why not?", "q": "Here is a cue!"}

# The 1st elem of myList feeds y
f("myEx", *myList, **myDict)
# x      = myEx
# y      = Left
# myArgs = ('Right', 'Up', 'Down')

Caveats

1. ** is exclusively reserved for dictionaries.
2. Non-optional argument assignment happens first.
3. You cannot use a non-optional argument twice.
4. If applicable, ** must come after *, always.

No, you will need scripting to place a click Event handler on the Element that does what you want.

ALTER TABLE YourTableNameHere ALTER COLUMN YourColumnNameHere VARCHAR(20) this is perfect for change to datatype

firstly shouldn't

data: $(this).serialize() + '&=NonFormValue' + NonFormValue,

be

data: $(this).serialize() + '&NonFormValue=' + NonFormValue,

and secondly you can use

url: this.action + '?NonFormValue=' + NonFormValue,

or if the action already contains any parameters

url: this.action + '&NonFormValue=' + NonFormValue,

Try adding a BindingResult parameter to methods annotated with @RequestMapping which have a @ModelAttribute annotated parameters. After each @ModelAttribute parameter, Spring looks for a BindingResult in the next parameter position (order is important).

So try changing:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) 
...

To:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) 
...

I was having the same issue, and got it to work by adding entries to /etc/security/limits.d/90-somefile.conf. Note that in order to see the limits working, I had to log out completely from the ssh session, and then log back in.

I wanted to set the limit for a specific user that runs a service, but it seems that I was getting the limit that was set for the user I was logging in as. Here's an example to show how the ulimit is set based on authenticated user, and not the effective user:

$ sudo cat /etc/security/limits.d/90-nofiles.conf
loginuser    soft    nofile   10240
loginuser    hard    nofile   10240
root         soft    nofile   10241
root         hard    nofile   10241
serviceuser  soft    nofile   10242
serviceuser  hard    nofile   10242

$ whoami
loginuser
$ ulimit -n
10240
$ sudo -i
# ulimit -n
10240    # loginuser's limit
# su - serviceuser
$ ulimit -n
10240    # still loginuser's limit.

You can use an * to specify an increase for all users. If I restart the service as the user I logged in, and add ulimit -n to the init script, I see that the initial login user's limits are in place. I have not had a chance to verify which user's limits are used during a system boot or of determining what the actual nofile limit is of the service I am running (which is started with start-stop-daemon).

There's 2 approaches that are working for now:

1. add a ulimit adjustment to the init script, just before start-stop-daemon.
2. wildcard or more extensive ulimit settings in the security file.

Full process (Unix svn package):

Check files are not in SVN:

> svn st -u folder 
? folder

Add all (including ignored files):

> svn add folder
A   folder
A   folder/file1.txt
A   folder/folder2
A   folder/folder2/file2.txt
A   folder/folderToIgnore
A   folder/folderToIgnore/fileToIgnore1.txt
A   fileToIgnore2.txt

Remove "Add" Flag to All * Ignore * files:

> cd folder

> svn revert --recursive folderToIgnore
Reverted 'folderToIgnore'
Reverted 'folderToIgnore/fileToIgnore1.txt'


> svn revert fileToIgnore2.txt
Reverted 'fileToIgnore2.txt'

Edit svn ignore on folder

svn propedit svn:ignore .

Add two singles lines with just the following:

folderToIgnore
fileToIgnore2.txt

Check which files will be upload and commit:

> cd ..

> svn st -u
A   folder
A   folder/file1.txt
A   folder/folder2
A   folder/folder2/file2.txt


> svn ci -m "Commit message here"

Strong:

• Property will not Destroy but Only once you set the property to nil will the object get destroyed
• By default all instance variables and local variables are strong pointers.
• You use strong only if you need to retain the object.
• We generally use strong for UIViewControllers (UI item's parents)
• IOS 4 (non-ARC) We Can Use Retain KeyWord
• IOS 5(ARC) We Can Use Strong Keyword

Example: @property (strong, nonatomic) ViewController *viewController;

@synthesize viewController;

Weak

By Default automatically get and set to nil

• We generally use weak for IBOutlets (UIViewController's Childs) and delegate
• the same thing as assign, no retain or release

Example : @property (weak, nonatomic) IBOutlet UIButton *myButton;

@synthesize myButton;

better tr command:

tr [:blank:] \\t

This will clean up the output of say, unzip -l , for further processing with grep, cut, etc.

e.g.,

unzip -l some-jars-and-textfiles.zip | tr [:blank:] \\t | cut -f 5 | grep jar

Here is how you can test which piece of code is faster:

% python -mtimeit  "l=[]"
10000000 loops, best of 3: 0.0711 usec per loop

% python -mtimeit  "l=list()"
1000000 loops, best of 3: 0.297 usec per loop

However, in practice, this initialization is most likely an extremely small part of your program, so worrying about this is probably wrong-headed.

Readability is very subjective. I prefer [], but some very knowledgable people, like Alex Martelli, prefer list() because it is pronounceable.

In the command prompt, type the command below and press Enter.

bcdedit /enum

Under the Windows Boot Loader sections, make note of the identifier value.

To start in safe mode from command prompt :

bcdedit /set {identifier} safeboot minimal 

Then enter the command line to reboot your computer.

Element.innerHTML is pretty much the way to go. Here are a few ways to use it:

HTML

<div class="results"></div>

JavaScript

// 'Modern' browsers (IE8+, use CSS-style selectors)
document.querySelector('.results').innerHTML = 'Hello World!';

// Using the jQuery library
$('.results').html('Hello World!');

If you just want to update a portion of a <div> I usually just add an empty element with a class like value or one I want to replace the contents of to the main <div>. e.g.

<div class="content">Hello <span class='value'></span></div>

Then I'd use some code like this:

// 'Modern' browsers (IE8+, use CSS-style selectors)
document.querySelector('.content .value').innerHTML = 'World!';

// Using the jQuery library
$(".content .value").html("World!");

Then the HTML/DOM would now contain:

<div class="content">Hello <span class='value'>World!</span></div>

You could also get the error if your Billing is not set up correctly.

Google hands out credit worth $300 or 12 months of free usage whichever runs out faster. After that you would need to enable billing.

Fiddler is the winner every time when comparing to Charles.

The "customize rules" feature of fiddler is unparalleled in any http debugger. The ability to write code to manipulate http requests and responses on-the-fly is invaluable to me and the work I do in web development.

There are so many features to fiddler that charles just does not have, and likely won't ever have. Fiddler is light-years ahead.

Here you can read more about different HTML parsers in Python and their performance. Even though the article is a bit dated it still gives you a good overview.

I'd recommend BeautifulSoup even though it isn't built in. Just because it's so easy to work with for those kinds of tasks. Eg:

import urllib2
from BeautifulSoup import BeautifulSoup

page = urllib2.urlopen('http://www.google.com/')
soup = BeautifulSoup(page)

x = soup.body.find('div', attrs={'class' : 'container'}).text

Run this command in your terminal:

$ java -version

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

I think that LINQ join clause isn't the correct solution to this problem, because of join clause purpose isn't to accumulate data in such way as required for this task solution. The code to merge created separate collections becomes too complicated, maybe it is OK for learning purposes, but not for real applications. One of the ways how to solve this problem is in the code below:

class Program
{
    static void Main(string[] args)
    {
        List<FirstName> firstNames = new List<FirstName>();
        firstNames.Add(new FirstName { ID = 1, Name = "John" });
        firstNames.Add(new FirstName { ID = 2, Name = "Sue" });

        List<LastName> lastNames = new List<LastName>();
        lastNames.Add(new LastName { ID = 1, Name = "Doe" });
        lastNames.Add(new LastName { ID = 3, Name = "Smith" });

        HashSet<int> ids = new HashSet<int>();
        foreach (var name in firstNames)
        {
            ids.Add(name.ID);
        }
        foreach (var name in lastNames)
        {
            ids.Add(name.ID);
        }
        List<FullName> fullNames = new List<FullName>();
        foreach (int id in ids)
        {
            FullName fullName = new FullName();
            fullName.ID = id;
            FirstName firstName = firstNames.Find(f => f.ID == id);
            fullName.FirstName = firstName != null ? firstName.Name : string.Empty;
            LastName lastName = lastNames.Find(l => l.ID == id);
            fullName.LastName = lastName != null ? lastName.Name : string.Empty;
            fullNames.Add(fullName);
        }
    }
}
public class FirstName
{
    public int ID;

    public string Name;
}

public class LastName
{
    public int ID;

    public string Name;
}
class FullName
{
    public int ID;

    public string FirstName;

    public string LastName;
}

If real collections are large for HashSet formation instead foreach loops can be used the code below:

List<int> firstIds = firstNames.Select(f => f.ID).ToList();
List<int> LastIds = lastNames.Select(l => l.ID).ToList();
HashSet<int> ids = new HashSet<int>(firstIds.Union(LastIds));//Only unique IDs will be included in HashSet

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

My async function

const getAllRedis = async (key) => {
  let obj = [];

  await client.hgetall(key, (err, object) => {
    console.log(object);
    _.map(object, (ob)=>{
      obj.push(JSON.parse(ob));
    })
    return obj;
    // res.send(obj);
});
}

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

Just thinking you might be feel unfamiliar of the sequence From->Where->Select, as in sql script, it is like Select->From->Where.

But you may not know that inside Sql Engine, it is also parse in the sequence of 'From->Where->Select', To validate it, you can try a simple script

select id as i from table where i=3

and it will not work, the reason is engine will parse Where before Select, so it won't know alias i in the where. To make this work, you can try

select * from (select id as i from table) as t where i = 3

If you are looking to remove usernames and passwords from your docker-compose.yml you can use Docker Secrets, here is how I have approached it.

version: '3.6'

services:
  db:
    image: mongo:3
    container_name: mycontainer
  secrets:
    - MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD
  environment:
    - MONGO_INITDB_ROOT_USERNAME_FILE=/var/run/secrets/MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD_FILE=/var/run/secrets/MONGO_INITDB_ROOT_PASSWORD
secrets:
  MONGO_INITDB_ROOT_USERNAME:
    file:  secrets/${NODE_ENV}_mongo_root_username.txt
  MONGO_INITDB_ROOT_PASSWORD:
    file:  secrets/${NODE_ENV}_mongo_root_password.txt

I have use the file: option for my secrets however, you can also use external: and use the secrets in a swarm.

The secrets are available to any script in the container at /var/run/secrets

The Docker documentation has this to say about storing sensitive data...

https://docs.docker.com/engine/swarm/secrets/

You can use secrets to manage any sensitive data which a container needs at runtime but you don’t want to store in the image or in source control, such as:

Usernames and passwords TLS certificates and keys SSH keys Other important data such as the name of a database or internal server Generic strings or binary content (up to 500 kb in size)

"but does that mean it should just be an example of the sort of expression you could use, or should it be an actual expression, that can be executed (eval etc..) to recreate the object? Or... should it be just a rehasing of the actual expression which was used, for pure information purposes?"

Wow, that's a lot of hand-wringing.

1. An "an example of the sort of expression you could use" would not be a representation of a specific object. That can't be useful or meaningful.

2. What is the difference between "an actual expression, that can ... recreate the object" and "a rehasing of the actual expression which was used [to create the object]"? Both are an expression that creates the object. There's no practical distinction between these. A repr call could produce either a new expression or the original expression. In many cases, they're the same.

Note that this isn't always possible, practical or desirable.

In some cases, you'll notice that repr() presents a string which is clearly not an expression of any kind. The default repr() for any class you define isn't useful as an expression.

In some cases, you might have mutual (or circular) references between objects. The repr() of that tangled hierarchy can't make sense.

In many cases, an object is built incrementally via a parser. For example, from XML or JSON or something. What would the repr be? The original XML or JSON? Clearly not, since they're not Python. It could be some Python expression that generated the XML. However, for a gigantic XML document, it might not be possible to write a single Python expression that was the functional equivalent of parsing XML.

One Google search later we've learned that you can set the entire plotting device background color as Owen indicates. If you just want the plotting region altered, you have to do something like what is outlined in that R-Help thread:

plot(df)
rect(par("usr")[1],par("usr")[3],par("usr")[2],par("usr")[4],col = "gray")
points(df)

The barplot function has an add parameter that you'll likely need to use.

Straightforward JavaScript Would Be the Following:

Append Before:

element.parentNode.insertBefore(newElement, element);

Append After:

element.parentNode.insertBefore(newElement, element.nextSibling);

But, Toss Some Prototypes In There For Ease of Use

By building the following prototypes, you will be able to call these function directly from newly created elements.

• newElement.appendBefore(element);

• newElement.appendAfter(element);

.appendBefore(element) Prototype

Element.prototype.appendBefore = function (element) {
  element.parentNode.insertBefore(this, element);
},false;

.appendAfter(element) Prototype

Element.prototype.appendAfter = function (element) {
  element.parentNode.insertBefore(this, element.nextSibling);
},false;

Removing natecarlson's repository

If you installed natecarlson's repository (either using add-apt-repository or manually added to /etc/apt/sources.list) and you don't want it anymore, open a terminal and run the following:

sudo -i

Enter your password if necessary, then paste the following into the terminal:

cd /etc/apt
sed -i '/natecarlson\/maven3/d' sources.list
cd sources.list.d
rm -f natecarlson-maven3-*.list*
apt-get update
exit
echo Done!

All you need to do is pass the JspWriter object into your method as a parameter i.e.

void someOutput(JspWriter stream)

Then call it via:

<% someOutput(out) %>

The writer object is a local variable inside _jspService so you need to pass it into your utility method. The same would apply for all the other built in references (e.g. request, response, session).

A great way to see whats going on is to use Tomcat as your server and drill down into the 'work' directory for the '.java' file generated from your 'jsp' page. Alternatively in weblogic you can use the 'weblogic.jspc' page compiler to view the Java that will be generated when the page is requested.

Tried this yet?

I like using the following to prevent things being outside my div elements. It helps with CSS rollovers too.

.marquee{
    overflow:hidden;
}

this will hide anything that moves/is outside of the div which will prevent the browser expanding and causing a scroll bar to appear.

A solution would be to declare your key as nvarchar(20).

Can do this, But not really necessary

How to do this

Jason Lee got the answer. When installing xCode I preferred keeping previous installations rather than replacing them. So I have these in my installation Folder

So /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs Contain different sdks. (Replace Xcode.app with correct number) copy previous sdks to

/Applications/Xcode 3.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

Here is my folder after I copied one.

Now restart xCode and you can set previous versions of sdks as base sdk.

Why it is not necessary

Refering Apple Documentaion

To use a particular SDK for an Xcode project, make two selections in your project’s build settings.

1. Choose a deployment target.

   This identifies the earliest OS version on which your software can run.

2. Choose a base SDK

   Your software can use features available in OS versions up to and including the one corresponding to the base SDK. By default , Xcode sets this to the newest OS supported by Xcode.

Rule is Use latest as base SDK and set deployment target to the minimum version app supposed to run

For example you can use iOS 7 as base sdk and set iOS 6 as deployment target. Run on iOS 6 simulator to test how it works on iOS 6. Install simulator if not available with list of simulators.

Additionaly You can unconditionally use features upto iOS 6. And Conditionally you can support new features of iOS 7 for new updated devices while supporting previous versions.

This can be done using Weakly Linked Classes ,Weakly Linked Methods, Functions, and Symbols

https://developer.apple.com/library/ios/documentation/developertools/conceptual/cross_development/Using/using.html#//apple_ref/doc/uid/20002000-SW3

Weak Linking

Suppose in Xcode you set the deployment target (minimum required version) to iOS6 and the target SDK (maximum allowed version) to iOS7. During compilation, the compiler would weakly link any interfaces that were introduced in iOS7 while strongly linking earlier interfaces. This would allow your application to continue running on iOS6 but still take advantage of newer features when they are available.

Use data type 'MultilineText':

[DataType(DataType.MultilineText)]
public string Text { get; set; }

See ASP.NET MVC3 - textarea with @Html.EditorFor

To find a very long list of words in big files, it can be more efficient to use egrep:

remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B

Don't be shy, throw an exception. Exceptions are a perfectly valid way to signal failure, and are much clearer than any return-code system. "Exceptional" has nothing to do with how often this can happen, and everything to do with what the class considers normal execution conditions. Throwing an exception when a division by zero occurs is just fine, regardless of how often the case can happen. If the problem is likely, guard your code so that the method doesn't get called with incorrect arguments.

the following bitwise operators: &, |, ^, and ~ return values (based on their input) in the same way logic gates affect signals. You could use them to emulate circuits.

That is the parent folder of bin which contains tomcat.exe file:

CATALINA_HOME='C:\Program Files\Apache Software Foundation\Tomcat 6.0'

CATALINA_BASE is the same as CATALINA_HOME.

NSString *myString = @"This";
NSString *test = [myString stringByAppendingString:@" is just a test"];

After a couple of years now with Objective C I think this is the best way to work with Objective C to achieve what you are trying to achieve.

Start keying in "N" in your Xcode application and it autocompletes to "NSString". key in "str" and it autocompletes to "stringByAppendingString". So the keystrokes are quite limited.

Once you get the hang of hitting the "@" key and tabbing the process of writing readable code no longer becomes a problem. It is just a matter of adapting.

To make a translation in the controller you could use $translate service:

$translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
    vm.si = translations['COMMON.SI'];
    vm.no = translations['COMMON.NO'];
});

That statement only does the translation on controller activation but it doesn't detect the runtime change in language. In order to achieve that behavior, you could listen the $rootScope event: $translateChangeSuccess and do the same translation there:

    $rootScope.$on('$translateChangeSuccess', function () {
        $translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
            vm.si = translations['COMMON.SI'];
            vm.no = translations['COMMON.NO'];
        });
    });

Of course, you could encapsulate the $translateservice in a method and call it in the controller and in the $translateChangeSucesslistener.

1. Click "Utilities and more" near the upper right corner of the screen after choosing your project
2. Choose "Project settings" from the drop down of the "Utilities and more" icon.

Now you may see trash icon and DELETE PROJECT button.

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

function Typer(callback)_x000D_

    var srcText = 'EXAMPLE ';_x000D_

I also prefer CSS over HTML; HTML is about content, CSS about presentation.

With CSS you have three options.

1. Inline CSS (like in Trevor's and Diodeus' solutions). Hard to maintain, and doesn't guarantee consistency: you'll have to check yourself that every image has the same border-width and border-color.
2. Internal stylesheet. Solves the consistency issue for all images on the page having class="hasBorder", but you'll have to include a stylesheet for each page, and again make sure "hasBorder" is defined the same each time.
3. External stylesheet. If you include a link to the external CSS file on each page all images with class="hasBorder" on all pages will have the same border.

Example using internal stylesheet:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
              "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Image with border</title>

<style type="text/css">
  img.hasBorder { border:15px solid #66CC33; }
</style>

</head>

<body>
  <img class="hasBorder" src="peggy.jpg" alt="" />
</body>
</html>

If you want an external stylesheet, replace the <style>...</style> block with

<link rel="stylesheet" type="text/css" href="somestylesheet.css" />

You may need user name and password:

mysqlcheck -A --auto-repair -uroot -p

You will be prompted for password.

mysqlcheck -A --auto-repair -uroot -p{{password here}}

If you want to put in cron, BUT your password will be visible in plain text!

The checked and selected attributes are allowed only two values, which are a copy of the attribute name and (from HTML 5 onwards) an empty string. Giving any other value is an error.

If you don't want to set the attribute, then the entire attribute must be omitted.

Note that in HTML 4 you may omit everything except the value. HTML 5 changed this to omit everything except the name (which makes no practical difference).

Thus, the complete (aside from variations in cAsE) set of valid representations of the attribute are:

<input ... checked="checked"> <!-- All versions of HTML / XHTML -->
<input ...          checked > <!-- Only HTML 4.01 and earlier -->
<input ... checked          > <!-- Only HTML 5 and later -->
<input ... checked=""       > <!-- Only HTML 5 and later -->

Documents served as text/html (HTML or XHTML) will be fed through a tag soup parser, and the presence of a checked attribute (with any value) will be treated as "This element should be checked". Thus, while invalid, checked="true", checked="yes", and checked="false" will all trigger the checked state.

I've not had any inclination to find out what error recovery mechanisms are in place for XML parsing mode should a different value be given to the attribute, but I would expect that the legacy of HTML and/or simple error recovery would treat it in the same way: If the attribute is there then the element is checked.

(And all the above applies equally to selected as it does to checked.)

If system_clock, this class have time_t conversion.

#include <iostream>
#include <chrono>
#include <ctime>

using namespace std::chrono;

int main()
{
  system_clock::time_point p = system_clock::now();

  std::time_t t = system_clock::to_time_t(p);
  std::cout << std::ctime(&t) << std::endl; // for example : Tue Sep 27 14:21:13 2011
}

example result:

Thu Oct 11 19:10:24 2012

EDIT: But, time_t does not contain fractional seconds. Alternative way is to use time_point::time_since_epoch() function. This function returns duration from epoch. Follow example is milli second resolution's fractional.

#include <iostream>
#include <chrono>
#include <ctime>

using namespace std::chrono;

int main()
{
  high_resolution_clock::time_point p = high_resolution_clock::now();

  milliseconds ms = duration_cast<milliseconds>(p.time_since_epoch());

  seconds s = duration_cast<seconds>(ms);
  std::time_t t = s.count();
  std::size_t fractional_seconds = ms.count() % 1000;

  std::cout << std::ctime(&t) << std::endl;
  std::cout << fractional_seconds << std::endl;
}

example result:

Thu Oct 11 19:10:24 2012

Open github app. Then, add the Folder of files into the github repo file onto your computer (You WILL need to copy the repo onto your computer. Most repo files are located in the following directory: C:\Users\USERNAME\Documents\GitHub\REPONAME) Then, in the github app, check our your repo. You can easily commit from there.

If you want to call these methods without including module in another class then you need to define them as module methods:

module UsefulThings
  def self.get_file; ...
  def self.delete_file; ...

  def self.format_text(x); ...
end

and then you can call them with

UsefulThings.format_text("xxx")

or

UsefulThings::format_text("xxx")

But anyway I would recommend that you put just related methods in one module or in one class. If you have problem that you want to include just one method from module then it sounds like a bad code smell and it is not good Ruby style to put unrelated methods together.

Using exit directly may be tricky as the script may be sourced from other places (e.g. from terminal). I prefer instead using subshell with set -e (plus errors should go into cerr, not cout) :

set -e
ERRCODE=0
my_command || ERRCODE=$?
test $ERRCODE == 0 ||
    (>&2 echo "My command failed ($ERRCODE)"; exit $ERRCODE)

It's nice that Go has a Duration type -- having explicitly defined units can prevent real-world problems.

And because of Go's strict type rules, you can't multiply a Duration by an integer -- you must use a cast in order to multiply common types.

/*
MultiplyDuration Hide semantically invalid duration math behind a function
*/
func MultiplyDuration(factor int64, d time.Duration) time.Duration {
    return time.Duration(factor) * d        // method 1 -- multiply in 'Duration'
 // return time.Duration(factor * int64(d)) // method 2 -- multiply in 'int64'
}

The official documentation demonstrates using method #1:

To convert an integer number of units to a Duration, multiply:

seconds := 10
fmt.Print(time.Duration(seconds)*time.Second) // prints 10s

But, of course, multiplying a duration by a duration should not produce a duration -- that's nonsensical on the face of it. Case in point, 5 milliseconds times 5 milliseconds produces 6h56m40s. Attempting to square 5 seconds results in an overflow (and won't even compile if done with constants).

By the way, the int64 representation of Duration in nanoseconds "limits the largest representable duration to approximately 290 years", and this indicates that Duration, like int64, is treated as a signed value: (1<<(64-1))/(1e9*60*60*24*365.25) ~= 292, and that's exactly how it is implemented:

// A Duration represents the elapsed time between two instants
// as an int64 nanosecond count. The representation limits the
// largest representable duration to approximately 290 years.
type Duration int64

So, because we know that the underlying representation of Duration is an int64, performing the cast between int64 and Duration is a sensible NO-OP -- required only to satisfy language rules about mixing types, and it has no effect on the subsequent multiplication operation.

If you don't like the the casting for reasons of purity, bury it in a function call as I have shown above.

It looks like you're running this on Windows (given your H://log.txt file path).

Try using \r\n instead of just \n.

Honestly, \n is fine; you're probably viewing the log file in notepad or something else that doesn't render non-Windows newlines. Try opening it in a different viewer/editor (e.g. Wordpad).

Tried out most of the solutions here and what helped me was cleaning the build folder in XCode using: Product - > Clean and rebuild the project

It is stored in the heap referenced by the class definition. If you think about it, it has nothing to do with stack because there is no scope.

I had a doubt that whether the encrypted text will be same for single text when encryption done by multiple times on a same text??

This depends strongly on the crypto algorithm you use:

• One goal of some/most (mature) algorithms is that the encrypted text is different when encryption done twice. One reason to do this is, that an attacker how known the plain and the encrypted text is not able to calculate the key.
• Other algorithm (mainly one way crypto hashes) like MD5 or SHA based on the fact, that the hashed text is the same for each encryption/hash.

I like the dynamic query way of Dave Rincon as it does not use cursors and is small and easy. Thank you Dave for sharing.

But for my needs on Azure SQL and with a "distinct" in the query, i had to modify the code like this:

Declare @SQL nvarchar(max);
-- Set SQL Variable
-- Prepare exec command for each distinctive tenantid found in Machines 
SELECT @SQL = (Select distinct 'exec dbo.sp_S2_Laser_to_cache ' + 
              convert(varchar(8),tenantid) + ';' 
              from Dim_Machine
              where iscurrent = 1
              FOR XML PATH(''))

--for debugging print the sql 
print @SQL;

--execute the generated sql script
exec sp_executesql @SQL;

I hope this helps someone...

You can force checkout your branch, if you do not want to commit your local changes.

git checkout -f branch_name

Actually MySQL provide a lot of easy to use function in daily life without more effort from user side-

NOW() it produce date and time both in current scenario whereas CURDATE() produce date only, CURTIME() display time only, we can use one of them according to our need with CAST or merge other calculation it, MySQL rich in these type of function.

NOTE:- You can see the difference using query select NOW() as NOWDATETIME, CURDATE() as NOWDATE, CURTIME() as NOWTIME ;

On top of @kp's answer:

I'm dealing with this and in my case, I have to show a child element and correct the height of the parent object accordingly (auto-sizing is not working in a bootstrap header for some reason I don't have time to debug).

But instead of using javascript to modify the parent, I think I'll dynamically add a CSS class to the parent and CSS-selectively show the children accordingly. This will maintain the decisions in the logic and not based on a CSS state.

tl;dr; apply the a and b styles to the parent <div>, not the child (of course, not everyone will be able to do this. i.e. Angular components making decisions of their own).

<style>
  .parent            { height: 50px; }
  .parent div        { display: none; }
  .with-children     { height: 100px; }
  .with-children div { display: block; }
</style>

<div class="parent">
  <div>child</div>
</div>

<script>
  // to show the children
  $('.parent').addClass('with-children');
</script>

today is 29th of January, +1 month means 29th of Fabruary, but because February consists of 28 days this year, it overlaps to the next day which is March 1st

You can use extension method, recursion to resolve this problem:

public static bool DeepCompare(this object obj, object another)
{     
  if (ReferenceEquals(obj, another)) return true;
  if ((obj == null) || (another == null)) return false;
  //Compare two object's class, return false if they are difference
  if (obj.GetType() != another.GetType()) return false;

  var result = true;
  //Get all properties of obj
  //And compare each other
  foreach (var property in obj.GetType().GetProperties())
  {
      var objValue = property.GetValue(obj);
      var anotherValue = property.GetValue(another);
      if (!objValue.Equals(anotherValue)) result = false;
  }

  return result;
 }

public static bool CompareEx(this object obj, object another)
{
 if (ReferenceEquals(obj, another)) return true;
 if ((obj == null) || (another == null)) return false;
 if (obj.GetType() != another.GetType()) return false;

 //properties: int, double, DateTime, etc, not class
 if (!obj.GetType().IsClass) return obj.Equals(another);

 var result = true;
 foreach (var property in obj.GetType().GetProperties())
 {
    var objValue = property.GetValue(obj);
    var anotherValue = property.GetValue(another);
    //Recursion
    if (!objValue.DeepCompare(anotherValue))   result = false;
 }
 return result;
}

or compare by using Json (if object is very complex) You can use Newtonsoft.Json:

public static bool JsonCompare(this object obj, object another)
{
  if (ReferenceEquals(obj, another)) return true;
  if ((obj == null) || (another == null)) return false;
  if (obj.GetType() != another.GetType()) return false;

  var objJson = JsonConvert.SerializeObject(obj);
  var anotherJson = JsonConvert.SerializeObject(another);

  return objJson == anotherJson;
}

If you don't add .0f it will be treated like it is an integer, and an integer division is a lot different from a floating point division indeed :)

float percent = (n * 100.0f) / v;

If you need an integer out of this you can of course cast the float or the double again in integer.

int percent = (int)((n * 100.0f) / v);

If you know your n value is less than 21474836 (that is (2 ^ 31 / 100)), you can do all using integer operations.

int percent = (n * 100) / v;

If you get NaN is because wathever you do you cannot divide for zero of course... it doesn't make sense.

Since I don't see the jQuery tag in the OP, here is a javascript only option :

document.addEventListener("DOMContentLoaded", function (event) {
    var _selector = document.querySelector('input[name=myCheckbox]');
    _selector.addEventListener('change', function (event) {
        if (_selector.checked) {
            // do something if checked
        } else {
            // do something else otherwise
        }
    });
});

Full Document height calculation:

To be more generic and find the height of any document you could just find the highest DOM Node on current page with a simple recursion:

;(function() {
    var pageHeight = 0;

    function findHighestNode(nodesList) {
        for (var i = nodesList.length - 1; i >= 0; i--) {
            if (nodesList[i].scrollHeight && nodesList[i].clientHeight) {
                var elHeight = Math.max(nodesList[i].scrollHeight, nodesList[i].clientHeight);
                pageHeight = Math.max(elHeight, pageHeight);
            }
            if (nodesList[i].childNodes.length) findHighestNode(nodesList[i].childNodes);
        }
    }

    findHighestNode(document.documentElement.childNodes);

    // The entire page height is found
    console.log('Page height is', pageHeight);
})();

I have used RxPY which has some nice threading functions to solve this in a fairly clean manner. No queues, and I have provided a function that runs on the main thread after completion of the background thread. Here is a working example:

import rx
from rx.scheduler import ThreadPoolScheduler
import time
import tkinter as tk

class UI:
   def __init__(self):
      self.root = tk.Tk()
      self.pool_scheduler = ThreadPoolScheduler(1) # thread pool with 1 worker thread
      self.button = tk.Button(text="Do Task", command=self.do_task).pack()

   def do_task(self):
      rx.empty().subscribe(
         on_completed=self.long_running_task, 
         scheduler=self.pool_scheduler
      )

   def long_running_task(self):
      # your long running task here... eg:
      time.sleep(3)
      # if you want a callback on the main thread:
      self.root.after(5, self.on_task_complete)

   def on_task_complete(self):
       pass # runs on main thread

if __name__ == "__main__":
    ui = UI()
    ui.root.mainloop()

Another way to use this construct which might be cleaner (depending on preference):

tk.Button(text="Do Task", command=self.button_clicked).pack()

...

def button_clicked(self):

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

Open the terminal or command prompt

Type

pip show django

or

pip3 show django

You can find any package version...

Example:

pip show tensorflow

pip show numpy

etc....

Finally, the wait is over with SQL Server 2016. They have introduced the Split string function, STRING_SPLIT:

select OtherID, cs.Value --SplitData
from yourtable
cross apply STRING_SPLIT (Data, ',') cs

All the other methods to split string like XML, Tally table, while loop, etc.. have been blown away by this STRING_SPLIT function.

Here is an excellent article with performance comparison: Performance Surprises and Assumptions: STRING_SPLIT.

For older versions, using tally table here is one split string function(best possible approach)

CREATE FUNCTION [dbo].[DelimitedSplit8K]
        (@pString VARCHAR(8000), @pDelimiter CHAR(1))

                     -- for both a performance gain and prevention of accidental "overruns"
                 SELECT TOP (ISNULL(DATALENGTH(@pString),0)) ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E4
                ),

                ),

You can try specifying the BaseException type explicitly. However, this will only catch derivatives of BaseException. While this includes all implementation-provided exceptions, it is also possibly to raise arbitrary old-style classes.

try:
  do_something()
except BaseException, e:
  logger.error('Failed to do something: ' + str(e))

I always use this generic function to prevent errrors on primitive variables as well as arrays and objects.

isset = function(obj) {
  var i, max_i;
  if(obj === undefined) return false;
  for (i = 1, max_i = arguments.length; i < max_i; i++) {
    if (obj[arguments[i]] === undefined) {
        return false;
    }
    obj = obj[arguments[i]];
  }
  return true;
};

console.log(isset(obj));                   // returns false
var obj = 'huhu';
console.log(isset(obj));                   // returns true
obj = {hallo:{hoi:'hoi'}};
console.log(isset(obj, 'niet'));           // returns false
console.log(isset(obj, 'hallo'));          // returns true
console.log(isset(obj, 'hallo', 'hallo')); // returns false
console.log(isset(obj, 'hallo', 'hoi'));   // returns true
