Use

public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
    return shouldOverrideUrlLoading(view, request.getUrl().toString());
}

How to reproduce this error with as few lines as possible:

>>> class C:
...   def f(self):
...     print "hi"
...
>>> C.f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method f() must be called with C instance as 
first argument (got nothing instead)

It fails because of TypeError because you didn't instantiate the class first, you have two choices: 1: either make the method static so you can run it in a static way, or 2: instantiate your class so you have an instance to grab onto, to run the method.

It looks like you want to run the method in a static way, do this:

>>> class C:
...   @staticmethod
...   def f():
...     print "hi"
...
>>> C.f()
hi

Or, what you probably meant is to use the instantiated instance like this:

>>> class C:
...   def f(self):
...     print "hi"
...
>>> c1 = C()
>>> c1.f()
hi
>>> C().f()
hi

If this confuses you, ask these questions:

1. What is the difference between the behavior of a static method vs the behavior of a normal method?
2. What does it mean to instantiate a class?
3. Differences between how static methods are run vs normal methods.
4. Differences between class and object.

int genid=gender.getCheckedRadioButtonId();
RadioButton radioButton = (RadioButton) findViewById(genid);
String gender=radioButton.getText().toString();

Hope this works. You can convert your output to string in the above manner. gender.getCheckedRadioButtonId(); - gender is the id of RadioGroup.

Object

input_data: Object price-row_122: " 35.1 " quantity-row_122: "1" success: true

The function component return type is limited to JSXElement | null in TypeScript. This is a current type limitation, pure React allows more return types.

Minimal demonstration snippet

You can either use a type assertion or Fragments as workaround:

const Aux = (props: AuxProps) => <>props.children</>; 
const Aux2 = (props: AuxProps) => props.children as ReactElement; 

ReactNode

children: React.ReactNode might be suboptimal, if the goal is to have strong types for Aux.

Almost anything can be assigned to current ReactNode type, which is equivalent to {} | undefined | null. A safer type for your case could be:

interface AuxProps {
  children: ReactElement | ReactElement[]
}

Example:

Given Aux needs React elements as children, we accidently added a string to it. Then above solution would error in contrast to ReactNode - take a look at the linked playgrounds.

Typed children are also useful for non-JSX props, like a Render Prop callback.

The only good solution to this problem can be found in the gulp documentation:

var gulp = require('gulp');

// takes in a callback so the engine knows when it'll be done
gulp.task('one', function(cb) {
  // do stuff -- async or otherwise
  cb(err); // if err is not null and not undefined, the orchestration will stop, and 'two' will not run
});

// identifies a dependent task must be complete before this one begins
gulp.task('two', ['one'], function() {
  // task 'one' is done now
});

gulp.task('default', ['one', 'two']);
// alternatively: gulp.task('default', ['two']);

Your desideratum,map.contains(key), is scheduled for the draft standard C++2a. In 2017 it was implemented by gcc 9.2. It's also in the current clang.

Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            googleMap.setMyLocationEnabled(true)
} else {
    // Show rationale and request permission.
}

Code is in Kotlin, hope you don't mind.

have fun

Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment

You could simply use

return

which does exactly the same as

return None

Your function will also return None if execution reaches the end of the function body without hitting a return statement. Returning nothing is the same as returning None in Python.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Some frameworks are using this header to detect xhr requests e.g. grails spring security is using this header to identify xhr request and give either a json response or html response as response.

Most Ajax libraries (Prototype, JQuery, and Dojo as of v2.1) include an X-Requested-With header that indicates that the request was made by XMLHttpRequest instead of being triggered by clicking a regular hyperlink or form submit button.

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

In Stored procedure, you return the values using OUT parameter ONLY. As you have defined two variables in your example:

   outstaticip OUT VARCHAR2, outcount OUT NUMBER

Just assign the return values to the out parameters i.e. outstaticip and outcount and access them back from calling location. What I mean here is: when you call the stored procedure, you will be passing those two variables as well. After the stored procedure call, the variables will be populated with return values.

If you want to have RETURN value as return from the PL/SQL call, then use FUNCTION. Please note that in case, you would be able to return only one variable as return variable.

My case is related to Greg B's -- Visual Studio creates two sites when SSL is enabled -- one for secure, and one for normal http requests. However Visual Studio chooses two ports at random, and depending on how you start the debugger you might be pointing towards the wrong page for the request type. Especially if you edit the URL but don't change the port number.

Seeing these posts jogged my memory.

I know this isn't APACHE related, but it is definitely a page that people with that error will find..

What it mentions as you type adb?

step1. >adb shell
step2. >cd data/data
step3. >ls -l|grep "your app package here"
step4. >cd "your app package here"
step5. >sqlite3 xx.db

Ugh. It's like someone gave up half way through implementing it and thought no one would notice.

For whatever reason, the answers above don't use the min and max attributes. This jQuery finishes it up:

    $('input[type="number"]').on('input change keyup paste', function () {
      if (this.min) this.value = Math.max(parseInt(this.min), parseInt(this.value) || 0);
      if (this.max) this.value = Math.min(parseInt(this.max), parseInt(this.value) || 0);
    });

It would probably also work as a named function "oninput" w/o jQuery if your one of those "jQuery-is-the-devil" types.

In addition to dustbuster's answer I needed to set path to the Xcode folder with this command:

sudo xcode-select -switch /Library/Developer/CommandLineTools

instead of

document.getElementById("txtBillingGroupName").value = groupName;

You can use

$("#txtBillingGroupName").val(groupName);

instead of groupName you can pass string value like "Group1"

What I like doing is overriding ToString() so that I get more useful output beyond the type name. This is handy in the debugger, you can see the information you want about an object without needing to expand it.

What you should do is to serialize your form data and send it to the controller action. ASP.NET MVC will bind the form data to the EditPostViewModel object( your action method parameter), using MVC model binding feature.

You can validate your form at client side and if everything is fine, send the data to server. The valid() method will come in handy.

$(function () {

    $("#yourSubmitButtonID").click(function (e) {

        e.preventDefault();
        var _this = $(this);
        var _form = _this.closest("form");

        var isvalid = _form .valid();  // Tells whether the form is valid

        if (isvalid)
        {           
           $.post(_form.attr("action"), _form.serialize(), function (data) {
              //check the result and do whatever you want
           })
        }

    });

});

Yes, a 32-bit architecture is limited to addressing a maximum of 4 gigabytes of memory. Depending on the operating system, this number can be cut down even further due to reserved address space.

This limitation can be removed on certain 32-bit architectures via the use of PAE (Physical Address Extension), but it must be supported by the processor. PAE eanbles the processor to access more than 4 GB of memory, but it does not change the amount of virtual address space available to a single process—each process would still be limited to a maximum of 4 GB of address space.

And yes, theoretically a 64-bit architecture can address 16.8 million terabytes of memory, or 2^64 bytes. But I don't believe the current popular implementations fully support this; for example, the AMD64 architecture can only address up to 1 terabyte of memory. Additionally, your operating system will also place limitations on the amount of supported, addressable memory. Many versions of Windows (particularly versions designed for home or other non-server use) are arbitrarily limited.

If you use rs.next() you will move the cursor, than you should to move first() why don't check using first() directly?

    public void fetchData(ResultSet res, JTable table) throws SQLException{     
    ResultSetMetaData metaData = res.getMetaData();
    int fieldsCount = metaData.getColumnCount();
    for (int i = 1; i <= fieldsCount; i++)
        ((DefaultTableModel) table.getModel()).addColumn(metaData.getColumnLabel(i));
    if (!res.first())
        JOptionPane.showMessageDialog(rootPane, "no data!");
    else

Like the answer previous, but I'd put ::before, just for stacking purposes. If you want to include text over the overlay (a common use case), using ::before will should fix that.

.dimmed {
  position: relative;
}

.dimmed:before {
  content: " ";
  z-index: 10;
  display: block;
  position: absolute;
  height: 100%;
  top: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.5);
}

If you need the path and thedomain for each cookie, which get_dict() is not exposes, you can parse the cookies manually, for instance:

[
    {'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
    for c in session.cookies
]

Hmmm I bet that in some previous lines you have something like:

list = set(something)

Am I wrong ?

Static libraries do not link with other static libraries. The only way to do this is to use your librarian/archiver tool (for example ar on Linux) to create a single new static library by concatenating the multiple libraries.

Edit: In response to your update, the only way I know to select only the symbols that are required is to manually create the library from the subset of the .o files that contain them. This is difficult, time consuming and error prone. I'm not aware of any tools to help do this (not to say they don't exist), but it would make quite an interesting project to produce one.

Need to convert the the key from hex to dec before base64_encoding and then send it for handshake.

Small variation with Swift 4.2...

On my UITableView I had many sections but I had to avoid the floating header effect so I used a "dummyViewHeight" approach as seen somewhere else here on Stack Overflow... So this is my solution for this problem (it works also for keyboard + toolbar + suggestions):

Declare it as class constant:

let dummyViewHeight: CGFloat = 40.0

Then

override func viewDidLoad() {
    super.viewDidLoad()
    //... some stuff here, not needed for this example

    // Create non floating header
    tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.size.width, height: dummyViewHeight))
    tableView.contentInset = UIEdgeInsets(top: -dummyViewHeight, left: 0, bottom: 0, right: 0)

    addObservers()
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    removeObservers()
}

And here all the magic...

@objc func keyboardWillShow(notification: NSNotification) {
    if let userInfo = notification.userInfo {
        let keyboardHeight = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as AnyObject).cgRectValue.size.height
        tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.bounds.size.width, height: dummyViewHeight))
        tableView.contentInset = UIEdgeInsets(top: -dummyViewHeight, left: 0, bottom: keyboardHeight, right: 0)
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    UIView.animate(withDuration: 0.25) {
        self.tableView.tableHeaderView = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.bounds.size.width, height: self.dummyViewHeight))
        self.tableView.contentInset = UIEdgeInsets(top: -self.dummyViewHeight, left: 0, bottom: 0, right: 0)
    }
}

I can't fault any of the answers here for the OP accepted one of them as resolving their problem. However, I found them flawed in one respect. When you output the result of the assignment to the variable, it contains numerous blank lines, not just the sought after answer. Example:

PS C:\brh> [datetime](Get-ItemProperty -Path .\deploy.ps1 -Name LastWriteTime).LastWriteTime

Friday, December 12, 2014 2:33:09 PM



PS C:\brh> 

I'm a fan of two things in code, succinctness and correctness. brianary has the right of it for succinctness with a tip of the hat to Roger Lipscombe but both miss correctness due to the extra lines in the result. Here's what I think the OP was looking for since it's what got me over the finish line.

PS C:\brh> (ls .\deploy.ps1).LastWriteTime.DateTime
Friday, December 12, 2014 2:33:09 PM

PS C:\brh> 

Note the lack of extra lines, only the one that PowerShell uses to separate prompts. Now this can be assigned to a variable for comparison or, as in my case, stored in a file for reading and comparison in a later session.

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>

Just the Code

# Set the HEAD to the old commit that we want to tag
git checkout 9fceb02

# temporarily set the date to the date of the HEAD commit, and add the tag
GIT_COMMITTER_DATE="$(git show --format=%aD | head -1)" \
git tag -a v1.2 -m"v1.2"

# set HEAD back to whatever you want it to be
git checkout master

Details

The answer by @dkinzer creates tags whose date is the current date (when you ran the git tag command), not the date of the commit. The Git help for tag has a section "On Backdating Tags" which says:

If you have imported some changes from another VCS and would like to add tags for major releases of your work, it is useful to be able to specify the date to embed inside of the tag object; such data in the tag object affects, for example, the ordering of tags in the gitweb interface.

To set the date used in future tag objects, set the environment variable GIT_COMMITTER_DATE (see the later discussion of possible values; the most common form is "YYYY-MM-DD HH:MM").

For example:

$ GIT_COMMITTER_DATE="2006-10-02 10:31" git tag -s v1.0.1

The page "How to Tag in Git" shows us that we can extract the time of the HEAD commit via:

git show --format=%aD  | head -1
#=> Wed, 12 Feb 2014 12:36:47 -0700

We could extract the date of a specific commit via:

GIT_COMMITTER_DATE="$(git show 9fceb02 --format=%aD | head -1)" \
git tag -a v1.2 9fceb02 -m "v1.2"

However, instead of repeating the commit twice, it seems easier to just change the HEAD to that commit and use it implicitly in both commands:

git checkout 9fceb02 

GIT_COMMITTER_DATE="$(git show --format=%aD | head -1)" git tag -a v1.2 -m "v1.2"

DROP EVENT IF EXISTS xxxEVENTxxx;
CREATE EVENT xxxEVENTxxx
  ON SCHEDULE
    EVERY 1 DAY
    STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL 1 HOUR)
  DO
    --process;

¡IMPORTANT!->

SET GLOBAL event_scheduler = ON;

Yes, you can do this. For example, to style the td tags that make up the different columns of a table you could do something like this:

table.myClass tr > td:first-child /* First column */
{
  /* some style here */
}
table.myClass tr > td:first-child+td /* Second column */
{
  /* some style here */
}
table.myClass tr > td:first-child+td+td /* Third column */
{
  /* some style here */
}

I could achieve a button using jQueryMobile with following code:

<label for="ppt" data-role="button" data-inline="true" data-mini="true" data-corners="false">Upload</label>
<input id="ppt" type="file" name="ppt" multiple data-role="button" data-inline="true" data-mini="true" data-corners="false" style="opacity: 0;"/>

Above code creates a "Upload" button (custom text). On click of upload button, file browse is launched. Tested with Chrome 25 & IE9.

You may consider using configure_file with the COPYONLY option:

configure_file(<input> <output> COPYONLY)

Unlike file(COPY ...) it creates a file-level dependency between input and output, that is:

If the input file is modified the build system will re-run CMake to re-configure the file and generate the build system again.

Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

In Java terms, Scala's Seq would be Java's List, and Scala's List would be Java's LinkedList.

Note that Seq is a trait, which is equivalent to Java's interface, but with the equivalent of up-and-coming defender methods. Scala's List is an abstract class that is extended by Nil and ::, which are the concrete implementations of List.

So, where Java's List is an interface, Scala's List is an implementation.

Beyond that, Scala's List is immutable, which is not the case of LinkedList. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).

Scala's List is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.

Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq, collection.mutable.Seq and collection.immutable.Seq, and it is the latter one that is the "default" imported into scope.

There's also GenSeq and ParSeq. The latter methods run in parallel where possible, while the former is parent to both Seq and ParSeq, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

In some applications TCP is faster (better throughput) than UDP.

This is the case when doing lots of small writes relative to the MTU size. For example, I read an experiment in which a stream of 300 byte packets was being sent over Ethernet (1500 byte MTU) and TCP was 50% faster than UDP.

The reason is because TCP will try and buffer the data and fill a full network segment thus making more efficient use of the available bandwidth.

UDP on the other hand puts the packet on the wire immediately thus congesting the network with lots of small packets.

You probably shouldn't use UDP unless you have a very specific reason for doing so. Especially since you can give TCP the same sort of latency as UDP by disabling the Nagle algorithm (for example if you're transmitting real-time sensor data and you're not worried about congesting the network with lot's of small packets).

@Inject instead of Spring’s @Autowired to inject a bean.
@Named instead of Spring’s @Component to declare a bean.

Those JSR-330 standard annotations are scanned and retrieved the same way as Spring annotation (as long as the following jar is in your classpath)

Since .NET 4.5 you can use combination of async and await with Progress for sending updates to UI thread:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

public void DoWork(IProgress<int> progress)
{
    // This method is executed in the context of

Tasks are currently the preferred way to implement what BackgroundWorker does.

There's no reasonable way to check whether a value has been initialized.

If you care about whether something has been initialized, instead of trying to check for it, put code into the constructor(s) to ensure that they are always initialized and be done with it.

Install:

gacutil -i "path_to_the_assembly"

View:

Open in Windows Explorer folder

• .NET 1.0 - NET 3.5: c:\windows\assembly (%systemroot%\assembly)
• .NET 4.x: %windir%\Microsoft.NET\assembly

OR gacutil –l

When you are going to install an assembly you have to specify where gacutil can find it, so you have to provide a full path as well. But when an assembly already is in GAC - gacutil know a folder path so it just need an assembly name.

• How to: Install an Assembly into the Global Assembly Cache

Sounds like we need to assume that your textbox name and ID are both set to "Tue." If that's the case, try using a lower-case V on .value.

Just to say I eventually solved this using index().

NOTHING else seemed to work.

So for sibling elements this is a good work around if you are first selecting by a common class and then want to modify something differently for each specific one.

EDIT: for those who don't know (like me) index() gives an index value for each element that matches the selector, counting from 0, depending on their order in the DOM. As long as you know how many elements there are with class="foo" you don't need an id.

Obviously this won't always help, but someone might find it useful.

If you're on a shared hosting environment you won't have access to the php.ini to make these changes, if you need access, a virtual private server (VPS) or a dedicated server may be a better option if you're confident in managing it yourself.

Alternatively if you create a new file called .htaccess in your root of your web directory (Ensure it doesn't contain a .txt extension if using notepad to create the file) and copy something like this inside.

php_value settingToChange 6000

This will only work if your hosting provider let's you override the certain config value. Best to ask if it doesn't work after trying.

You can try this

$('#startdate').val()

or

$('#startdate').data('date')

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

1. Go to the directory

   cd /usr/local
   

2. Remove it with super user privileges

   sudo rm -rf go
   

Sorry for being late on the party. Depending on your server configuration, You may be required to specify character strictly with lowercase letters utf-8, otherwise it will be ignored. Try this if you end up here searching for solutions and none of answers above helps:

$mail->CharSet = "UTF-8";

should be replaced with:

$mail->CharSet = "utf-8";

I have found answers to my confusions.

There is a very important difference between the root and the alias directives. This difference exists in the way the path specified in the root or the alias is processed.

In case of the root directive, full path is appended to the root including the location part, whereas in case of the alias directive, only the portion of the path NOT including the location part is appended to the alias.

To illustrate:

Let's say we have the config

location /static/ {
    root /var/www/app/static/;
    autoindex off;
}

In this case the final path that Nginx will derive will be

/var/www/app/static/static

This is going to return 404 since there is no static/ within static/

This is because the location part is appended to the path specified in the root. Hence, with root, the correct way is

location /static/ {
    root /var/www/app/;
    autoindex off;
}

On the other hand, with alias, the location part gets dropped. So for the config

location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ?
}                            |
                             pay attention to this trailing slash

the final path will correctly be formed as

/var/www/app/static

The case of trailing slash for alias directive

There is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.

A few more places have discussed this, not conclusively though.

https://serverfault.com/questions/376162/how-can-i-create-a-location-in-nginx-that-works-with-and-without-a-trailing-slas

https://serverfault.com/questions/375602/why-is-my-nginx-alias-not-working

PowerShell is pretty common these days so I use it often as a quick way to invoke C# since that has functions for pretty much everything:

@echo off
set pathToResolve=%~dp0\..\SomeFile.txt
for /f "delims=" %%a in ('powershell -Command "[System.IO.Path]::GetFullPath( '%projectDirMc%' )"') do @set resolvedPath=%%a

echo Resolved path: %resolvedPath%

It's a bit slow, but the functionality gained is hard to beat unless without resorting to an actual scripting language.

$('.btnMedio').click(function(event) {
    // Preventing default action of the event
    event.preventDefault();
    // Getting the height of the document
    var n = $(document).height();
    $('html, body').animate({ scrollTop: n }, 50);
//                                       |    |
//                                       |    --- duration (milliseconds) 
//                                       ---- distance from the top
});

Disabled is a Boolean Attribute of the select element as stated by WHATWG, that means the RIGHT WAY TO DISABLE with jQuery would be

jQuery("#selectId").attr('disabled',true);

This would make this HTML

<select id="selectId" name="gender" disabled="disabled">
    <option value="-1">--Select a Gender--</option>
    <option value="0">Male</option>
    <option value="1">Female</option>
</select>

This works for both XHTML and HTML (W3School reference)

Yet it also can be done using it as property

jQuery("#selectId").prop('disabled', 'disabled');

getting

<select id="selectId" name="gender" disabled>

Which only works for HTML and not XTML

NOTE: A disabled element will not be submitted with the form as answered in this question: The disabled form element is not submitted

NOTE2: A disabled element may be greyed out.

NOTE3:

A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.

TL;DR

<script>
    var update_pizza = function () {
        if ($("#pizza").is(":checked")) {
            $('#pizza_kind').attr('disabled', false);
        } else {
            $('#pizza_kind').attr('disabled', true);
        }
    };
    $(update_pizza);
    $("#pizza").change(update_pizza);
</script>

To ignore untracked files just go to .git/info/exclude. Exclude is a file with a list of ignored extensions or files.

This problem is because you did not import the module

import {RouterModule} from '@angular/router';

And you must declare this modulce in the import section

   imports:[RouterModule]

A better solution is explained in the official explanation. I left the answer I have given before under the horizontal line.

According to the solution there:

Use an external tag and write down the following code below in the top-level build.gradle file. You're going to change the version to a variable rather than a static version number.

ext {
    compileSdkVersion = 26
    supportLibVersion = "27.1.1"
}

Change the static version numbers in your app-level build.gradle file, the one has (Module: app) near.

android {
    compileSdkVersion rootProject.ext.compileSdkVersion // It was 26 for example
    // the below lines will stay
}

// here there are some other stuff maybe

dependencies {
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    // the below lines will stay
}

Sync your project and you'll get no errors.

You don't need to add anything to Gradle scripts. Install the necessary SDKs and the problem will be solved.

In your case, install the libraries below from Preferences > Android SDK or Tools > Android > SDK Manager

For Angular 6.1+ , you can use default pipe keyvalue ( Do review and upvote also ) :

<ul>
    <li *ngFor="let recipient of map | keyvalue">
        {{recipient.key}} --> {{recipient.value}}
    </li>
</ul>

WORKING DEMO

For the previous version :

One simple solution to this is convert map to array : Array.from

Component Side :

map = new Map<String, String>();

constructor(){
    this.map.set("sss","sss");
    this.map.set("aaa","sss");
    this.map.set("sass","sss");
    this.map.set("xxx","sss");
    this.map.set("ss","sss");
    this.map.forEach((value: string, key: string) => {
        console.log(key, value);
    });
}

getKeys(map){
    return Array.from(map.keys());
}

Template Side :

<ul>
  <li *ngFor="let recipient of getKeys(map)">
    {{recipient}}
   </li>
</ul>

WORKING DEMO

to remove all unused containers, volumes, networks and images at once (https://docs.docker.com/engine/reference/commandline/system_prune/#related-commands):

docker system prune -a -f --volumes

if it's not enough, one can remove running containers first:

docker rm -f $(docker ps -a -q)
docker system prune -a -f --volumes

increasing /var/lib/docker or using another location with more space is also a good alternative to get rid of this error (see How to change the docker image installation directory?)

Is there any disadvantages/consequences of pushing empty commits?

Aside from the extreme confusion someone might get as to why there's a bunch of commits with no content in them on master, not really.

You can change the commit that you pushed to remote, but the sha1 of the commit (basically it's id number) will change permanently, which alters the source tree -- You'd then have to do a git push -f back to remote.

You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.

I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.

import cv2
import os

image_folder = 'images'
video_name = 'video.avi'

images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape

video = cv2.VideoWriter(video_name, 0, 1, (width,height))

for image in images:
    video.write(cv2.imread(os.path.join(image_folder, image)))

cv2.destroyAllWindows()
video.release()

That is a constraint on the generic parameter T. It must be a class (reference type) and must have a public parameter-less default constructor.

That means T can't be an int, float, double, DateTime or any other struct (value type).

It could be a string, or any other custom reference type, as long as it has a default or parameter-less constructor.

I was getting the same UnicodeEncodeError when saving scraped web content to a file. To fix it I replaced this code:

with open(fname, "w") as f:
    f.write(html)

with this:

import io
with io.open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Using io gives you backward compatibility with Python 2.

If you only need to support Python 3 you can use the builtin open function instead:

with open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Yes , Jared and Kelly Orr are right. I use the following code like in edit exception.

foreach (var issue in dinner.GetRuleViolations())
{
    ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage);
}

in stead of

ModelState.AddRuleViolations(dinner.GetRuleViolations());

Update:

Separate the event and property bindings:

<select [ngModel]="selectedItem" (ngModelChange)="onChange($event)">

onChange(newValue) {
    console.log(newValue);
    this.selectedItem = newValue;  // don't forget to update the model here
    // ... do other stuff here ...
}

You could also use

<select [(ngModel)]="selectedItem" (ngModelChange)="onChange($event)">

and then you wouldn't have to update the model in the event handler, but I believe this causes two events to fire, so it is probably less efficient.

Old answer, before they fixed a bug in beta.1:

Create a local template variable and attach a (change) event:

<select [(ngModel)]="selectedItem" #item (change)="onChange(item.value)">

My solution is a class to sort listView items when you click on column header.

You can specify the type of each column.

listView.ListViewItemSorter = new ListViewColumnSorter();
listView.ListViewItemSorter.ColumnsTypeComparer.Add(0, DateTime);
listView.ListViewItemSorter.ColumnsTypeComparer.Add(1, int);

That's it !

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

echo "C:\Users\San.Tan\My Folder\project1" | sed -e 's/C:\\/mnt\/c\//;s/\\/\//g'

replaces

C:\Users\San.Tan\My Folder\project1

to

mnt/c/Users/San.Tan/My Folder/project1

in case someone needs to replace windows paths to Windows Subsystem for Linux(WSL) paths

In java.lang.String, the replace method either takes a pair of char's or a pair of CharSequence's (of which String is a subclass, so it'll happily take a pair of String's). The replace method will replace all occurrences of a char or CharSequence. On the other hand, the first String arguments of replaceFirst and replaceAll are regular expressions (regex). Using the wrong function can lead to subtle bugs.

According to official documentation: Creating REST Controllers with the @RestController annotation

@RestController is a stereotype annotation that combines @ResponseBody and @Controller. More than that, it gives more meaning to your Controller and also may carry additional semantics in future releases of the framework.

It seems that it's best to use @RestController for clarity, but you can also combine it with ResponseEntity for flexibility when needed (According to official tutorial and the code here and my question to confirm that).

For example:

@RestController
public class MyController {

    @GetMapping(path = "/test")
    @ResponseStatus(HttpStatus.OK)
    public User test() {
        User user = new User();
        user.setName("Name 1");

        return user;
    }

}

is the same as:

@RestController
public class MyController {

    @GetMapping(path = "/test")
    public ResponseEntity<User> test() {
        User user = new User();
        user.setName("Name 1");

        HttpHeaders responseHeaders = new HttpHeaders();
        // ...
        return new ResponseEntity<>(user, responseHeaders, HttpStatus.OK);
    }

}

This way, you can define ResponseEntity only when needed.

Update

You can use this:

    return ResponseEntity.ok().headers(responseHeaders).body(user);

List is interface and ArrayList is implemented concrete class. It is always recommended to use.

List<String> arrayList = new ArrayList<String>();

Because here list reference is flexible. It can also hold LinkedList or Vector object.

Copy a file to the emulator:

Open emulator and File Explorer (Finder in Mac) side by side. Choose the file you want to copy then Drag and Drop the file onto the emulator. The selected file will be copied to the Downloads folder of the emulator.

How to view files in Android Studio:

Android Studio has Device Explorer to explore emulator content (Earlier we used to have DDMS, which is deprecated in Studio 3+). Goto View -> Tools Window -> Device File Explorer and you can see the explorer window. Goto Storage -> emulated -> 0 ->Download, if you don't see the file here, please restart the emulator and that's it.

Note: You don't see Device Explorer if you have opened a Flutter project.

You can also view the image files in Android Studio by double-clicking the file in the emulator.

gensim.utils.deaccent(text) from Gensim - topic modelling for humans:

'Sef chomutovskych komunistu dostal postou bily prasek'

Another solution is unidecode.

Note that the suggested solution with unicodedata typically removes accents only in some character (e.g. it turns 'l' into '', rather than into 'l').

I use ­, inserted manually where necessary.

I always find it a pity that people don’t use techniques because there is some—maybe old or strange—browser around which doesn’t handle them the way they were specified. I found that ­ is working properly in both recent Internet Explorer and Firefox browsers, that should be enough. You may include a browser check telling people to use something mature or continue at their own risk if they come around with some strange browser.

Syllabification isn’t that easy and I cannot recommend leaving it to some Javascript. It’s a language specific topic and may need to be carefully revised by the deskman if you don’t want it to turn your text irritating. Some languages, such as German, form compound words and are likely to lead to decomposition problems. E.g. Spargelder (germ. saved money, pl.) may, by syllabification rules, be wrapped in two places (Spar-gel-der). However, wrapping it in the second position, turns the first part to show up as Spargel- (germ. asparagus), activating a completely misleading concept in the head of the reader and therefore shoud be avoided.

And what about the string Wachstube? It could either mean ‘guardroom’ (Wach-stu-be) or ‘tube of wax’ (Wachs-tu-be). You may probably find other examples in other languages as well. You should aim to provide an environment in which the deskman can be supported in creating a well-syllabified text, proof-reading every critical word.

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

The %c conversion specifier won't automatically skip any leading whitespace, so if there's a stray newline in the input stream (from a previous entry, for example) the scanf call will consume it immediately.

One way around the problem is to put a blank space before the conversion specifier in the format string:

scanf(" %c", &c);

The blank in the format string tells scanf to skip leading whitespace, and the first non-whitespace character will be read with the %c conversion specifier.

    <!-- You can omit below tag if you don't need stroke -->
   <stroke android:color="#3b91d7" android:width="5dp"/>

    <!-- Set the same value for both width and height to get a circular shape -->

You can use this in event:

google.maps.event.addListener(marker, 'click', function() {  
    // this = marker
    var marker_map = this.getMap();
    this.info.open(marker_map);
    // this.info.open(marker_map, this);
    // Note: If you call open() without passing a marker, the InfoWindow will use the position specified upon construction through the InfoWindowOptions object literal.
});

A simple way would be:

 var newDt= dt.AsEnumerable()
                 .GroupBy(x => x.Field<int>("ColumnName"))
                 .Select(y => y.First())
                 .CopyToDataTable();

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

It occurred to me that you may have actually be asking how to implement the + operator for dictionaries, the following seems to work:

>>> class Dict(dict):
...     def __add__(self, other):
...         copy = self.copy()
...         copy.update(other)
...         return copy
...     def __radd__(self, other):
...         copy = other.copy()
...         copy.update(self)
...         return copy
... 
>>> default_data = Dict({'item1': 1, 'item2': 2})
>>> default_data + {'item3': 3}
{'item2': 2, 'item3': 3, 'item1': 1}
>>> {'test1': 1} + Dict(test2=2)
{'test1': 1, 'test2': 2}

Note that this is more overhead then using dict[key] = value or dict.update(), so I would recommend against using this solution unless you intend to create a new dictionary anyway.

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

The print function in python adds itself \n

You could use

import sys
sys.stdout.write(a)

instead

Easiest and clearest way I'd say is:

var maxHeight = 0, maxHeightElement = null;
$('.panel').each(function(){
   if ($(this).height() > maxHeight) {
       maxHeight = $(this).height();
       maxHeightElement = $(this);
   }
});

This happens when the files inside the Debug and Release folder are not created properly(Either they are having wrong reference or having overwritten many times). I have faced the same problem in which, i everything works fine when we build the solution, but when i publish the website it gives me same error. I have solved this in following manner:

1. Go to your Solution Explorer in Visual Studio and click on show hidden files (if they are not showing ! )
2. you will find a folder named obj, open it .
3. Here there are again 2 folder named respectively as Debug and Release. Now, delete the content from these two folder, Make sure that you do not delete the folders Debug and Release. Only delete the files and folders inside Debug and Release folder.
4. Now build and publish your solution and everything will work like charm.

git pull is really equivalent to running git fetch and then git merge. The git fetch updates your so-called "remote-tracking branches" - typically these are ones that look like origin/master, github/experiment, etc. that you see with git branch -r. These are like a cache of the state of branches in the remote repository that are updated when you do git fetch (or a successful git push).

So, suppose you've got a remote called origin that refers to your GitHub repository, you would do:

git fetch origin

... and then do:

git diff master origin/master

... in order to see the difference between your master, and the one on GitHub. If you're happy with those differences, you can merge them in with git merge origin/master, assuming master is your current branch.

Personally, I think that doing git fetch and git merge separately is generally a good idea.

T.T = Turn around Time = C.T - A.T

W.T = Waiting Time = T.T - B.T

Here is the preemptive SJF Note: each process will preempt at time a new process arrives.Then it will compare the burst times and will allocate the process which have shortest burst time. But if two process have same burst time then the process which came first that will be allocated first just like FCFS.

If this persists even after clearing provisioning profile and re-downloading them, then it might be due to the bundle ID already registered in Apple's MDM push certificate.

A couple of issues arise when trying to reload/source ~/.profile file. [This refers to Ubuntu linux - in some cases the details of the commands will be different]

1. Are you running this directly in terminal or in a script?
2. How do you run this in a script?

Ad. 1)

Running this directly in terminal means that there will be no subshell created. So you can use either two commands:

source ~/.bash_profile

or

. ~/.bash_profile

In both cases this will update the environment with the contents of .profile file.

Ad 2) You can start any bash script either by calling

sh myscript.sh 

or

. myscript.sh

In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process. After finishing the subshell command none of the exports etc. will not be applied. THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME.

In order for your changes applied in your script to have effect for the global environment the script has to be run with

.myscript.sh

command.

In order to make sure that you script is not runned in a subshel you can use this function. (Again example is for Ubuntu shell)

#/bin/bash

preventSubshell(){
  if [[ $_ != $0 ]]
  then
    echo "Script is being sourced"
  else
    echo "Script is a subshell - please run the script by invoking . script.sh command";
    exit 1;
  fi
}

I hope this clears some of the common misunderstandings! :D Good Luck!

The following is not exactly the same but similar, I was searching for a snippet to add a call to the interface method, but found this question, so I decided to add this snippet for those who were searching for it like me and found this question:

 public class MyClass
 {
        //... class code goes here

        public interface DataLoadFinishedListener {
            public void onDataLoadFinishedListener(int data_type);
        }

        private DataLoadFinishedListener m_lDataLoadFinished;

        public void setDataLoadFinishedListener(DataLoadFinishedListener dlf){
            this.m_lDataLoadFinished = dlf;
        }



        private void someOtherMethodOfMyClass()
        {
            m_lDataLoadFinished.onDataLoadFinishedListener(1);
        }    
    }

Usage is as follows:

myClassObj.setDataLoadFinishedListener(new MyClass.DataLoadFinishedListener() {
            @Override
            public void onDataLoadFinishedListener(int data_type) {
                }
            });

Dim a As Range, b As Range

Set a = Selection

For Each b In a.Rows
    MsgBox b.Address
Next

Here you go:

input[type=text] { text-align:right }

<form>_x000D_
    <input type="text" name="name" value="">_x000D_
</form>

This approach worked for me:

• Close VS2015
• Open the solution temporarily in VS2013 and enable nuget package restore by right clicking on the solution (i also did a rebuild, but I suspect that is not needed).
• Close VS2013
• Reopen the solution in VS2015

You have now enabled nuget package restore in VS2015 as well.

Here's a pretty solid solution that incorporates the best ideas so far as well as includes my solution to a problem highlighted with Offerein's. No javascript is used.

If you care about backwards compatibility with IE (and even Edge 13), you can't use the form="your-form" attribute.

Use a standard submit input with display none and add a label for it outside the form:

<form id="your-form">
  <input type="submit" id="your-form-submit" style="display: none;">
</form>

Note the use of display: none;. This is intentional. Using bootstrap's .hidden class conflicts with jQuery's .show() and .hide(), and has since been deprecated in Bootstrap 4.

Now simply add a label for your submit, (styled for bootstrap):

<label for="your-form-submit" role="button" class="btn btn-primary" tabindex="0">
  Submit
</label>

Unlike other solutions, I'm also using tabindex - set to 0 - which means that we are now compatible with keyboard tabbing. Adding the role="button" attribute gives it the CSS style cursor: pointer. Et voila. (See this fiddle).

The most effective solution that I found is to define the parent element with display:flex and align-items:center

LIVE DEMO

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <style>
      .myclass{
        display:flex;
        align-items:center;
        background-color:grey;
        color:#fff;
        height:50px;
      }
    </style>
  </head>
  <body>
    <div class="myclass">
      <input type="checkbox">
      <label>do you love Ananas?
      </label>
    </div>
  </body>
</html>

OUTPUT:

The latest version of SQL Server (2012) permits the following.

SELECT 
    RowID, 
    Col1,
    SUM(Col1) OVER(ORDER BY RowId ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Col2
FROM tablehh
ORDER BY RowId

or

SELECT 
    GroupID, 
    RowID, 
    Col1,
    SUM(Col1) OVER(PARTITION BY GroupID ORDER BY RowId ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Col2
FROM tablehh
ORDER BY RowId

This is even faster. Partitioned version completes in 34 seconds over 5 million rows for me.

Thanks to Peso, who commented on the SQL Team thread referred to in another answer.

Assembly.GetExecutingAssembly().Location

On my Ubuntu 13.04, I tried quite a few tweaks before succeeding with this:

1. Edit /etc/init/jenkins.conf
2. Locate the spot where "exec start-stop-server..." begins
3. Insert the environment update just before that, i.e.

export PATH=$PATH:/some/new/path/bin

I usually go with varchar(255) (255 being the maximum length of a varchar type in MySQL).

For Word Wrapping in Php Storm 1. Select File from the menu 2. From File select setting 3. From setting select Editor 4. Select General from Editor 5. In general checked Use soft wraps in editor from Soft wraps section

rootLayout.findFocus().clearFocus();

If you right-click on your project, there should be an option under "maven" to "enable dependency management". That's it.

If you are concerned about speed (say you have a looong list of strings) and you know the nature of the newline char, string slicing is actually faster than rstrip. A little test to illustrate this:

import time

loops = 50000000

def method1(loops=loops):
    test_string = 'num\n'
    t0 = time.time()
    for num in xrange(loops):
        out_sting = test_string[:-1]
    t1 = time.time()
    print('Method 1: ' + str(t1 - t0))

def method2(loops=loops):
    test_string = 'num\n'
    t0 = time.time()
    for num in xrange(loops):
        out_sting = test_string.rstrip()
    t1 = time.time()
    print('Method 2: ' + str(t1 - t0))

method1()
method2()

Output:

Method 1: 3.92700004578
Method 2: 6.73000001907

I worked on this issue for a few days. Installed all packages, modified web.config and still had the same problem. I finally removed

<assemblies>
<add assembly="Microsoft.ReportViewer.Common, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</assemblies>

from the web.config and it worked. No exactly sure why it didn't work with the tags in the web.config file. My guess there is a conflict with the GAC and the BIN folder.

Here is my web.config file:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu". Once this is done, you can open an admin powershell window via Win+X,A or by right-clicking on the start button and selecting "Windows Powershell (Admin)":

[

Here's where you replace the "Command Prompt" option with a "Windows Powershell" option:

There is another approach. It uses List.FindIndex and List.RemoveAt.

While I would probably use the solution presented by KeithS (just the simple Where/ToList) this approach differs in that it mutates the original list object. This can be a good (or a bad) "feature" depending upon expectations.

In any case, the FindIndex (coupled with a guard) ensures the RemoveAt will be correct if there are gaps in the IDs or the ordering is wrong, etc, and using RemoveAt (vs Remove) avoids a second O(n) search through the list.

Here is a LINQPad snippet:

var list = new List<int> { 1, 3, 2 };
var index = list.FindIndex(i => i == 2); // like Where/Single
if (index >= 0) {   // ensure item found
    list.RemoveAt(index);
}
list.Dump();        // results -> 1, 3

Happy coding.

As per https://kb.informatica.com/solution/23/Pages/69/570664.aspx adding this property works

This way of specifying the encoding of a Python file comes from PEP 0263 - Defining Python Source Code Encodings.

It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don't know if it was the first program to use that syntax.

For multiple lines

In chrome, you can apply this css if you need to apply ellipsis on multiple lines.

You can also add width in your css to specify element of certain width:

.multi-line-ellipsis {_x000D_
    overflow: hidden;_x000D_
    display: -webkit-box;_x000D_
    -webkit-line-clamp: 3;_x000D_
    -webkit-box-orient: vertical;_x000D_
}

<p class="multi-line-ellipsis">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>

string startTime = "7:00 AM";
string endTime = "2:00 PM";

TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));

Console.WriteLine(duration);
Console.ReadKey();

Will output: 07:00:00.

It also works if the user input military time:

string startTime = "7:00";
string endTime = "14:00";

TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));

Console.WriteLine(duration);
Console.ReadKey();

Outputs: 07:00:00.

To change the format: duration.ToString(@"hh\:mm")

Addendum:

Over the years it has somewhat bothered me that this is the most popular answer I have ever given; the original answer never actually explained why the OP's code didn't work despite the fact that it is perfectly valid. The only reason it gets so many votes is because the post comes up on Google when people search for a combination of the terms "C#", "timespan", and "between".

• from a directory_of_modules, you can import a specific_module.py
• this specific_module.py, can contain a Class with some_methods() or just functions()
• from a specific_module.py, you can instantiate a Class or call functions()
• from this Class, you can execute some_method()

Example:

#!/usr/bin/python3
from directory_of_modules import specific_module
instance = specific_module.DbConnect("username","password")
instance.login()

Excerpts from PEP 8 - Style Guide for Python Code:

Modules should have short and all-lowercase names.

Notice: Underscores can be used in the module name if it improves readability.

A Python module is simply a source file(*.py), which can expose:

• Class: names using the "CapWords" convention.

• Function: names in lowercase, words separated by underscores.

• Global Variables: the conventions are about the same as those for Functions.

I have resolved the issue by adding below code snippet into node.js file.

app.get("/*", function (request, response) {
    console.log('Unknown API called');
    response.redirect('/#' + request.url);
});

Note : when we refresh the page, it will look for the API instead of Angular page (Because of no # tag in URL.) . Using the above code, I am redirecting to the url with #

You can try to do my answer,

you wrote this:

<?php
foreach($group_membership as $i => $username) {
    $items = array($username);
}

print_r($items);
?>

And in your case I would do this:

<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
    $items[] = $username;
} ?>

As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)

<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
    $items[] = $username; 
} 
?>

while is faster, but the last example is only a result of an observation. :)

Here's a (Tested) Extension Method, with comments to help you out.

using IWshRuntimeLibrary;
using System;

namespace Extensions
{
    public static class XShortCut
    {
        /// <summary>
        /// Creates a shortcut in the startup folder from a exe as found in the current directory.
        /// </summary>
        /// <param name="exeName">The exe name e.g. test.exe as found in the current directory</param>
        /// <param name="startIn">The shortcut's "Start In" folder</param>
        /// <param name="description">The shortcut's description</param>
        /// <returns>The folder path where created</returns>
        public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description)
        {
            var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath();
            var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk";
            var targetPath = Environment.CurrentDirectory + @"\" + exeName;
            XFile.Delete(linkPath);
            Create(linkPath, targetPath, startIn, description);
            return startupFolderPath;
        }

        /// <summary>
        /// Create a shortcut
        /// </summary>
        /// <param name="fullPathToLink">the full path to the shortcut to be created</param>
        /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param>
        /// <param name="startIn">Start in this folder</param>
        /// <param name="description">Description for the link</param>
        public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description)
        {
            var shell = new WshShell();
            var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink);
            link.IconLocation = fullPathToTargetExe;
            link.TargetPath = fullPathToTargetExe;
            link.Description = description;
            link.WorkingDirectory = startIn;
            link.Save();
        }
    }
}

And an example of use:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory,
    "Starts some executable in the current directory of application");

1st parm sets the exe name (found in the current directory) 2nd parm is the "Start In" folder and 3rd parm is the shortcut description.

The naming convention of the link leaves no ambiguity as to what it will do. To test the link just double click it.

Final Note: the application itself (target) must have an ICON image associated with it. The link is easily able to locate the ICON within the exe. If the target application has more than one icon, you may open the link's properties and change the icon to any other found in the exe.

I think you can just use window.parent from the iframe. window.parent returns the window object of the parent page, so you could do something like:

window.parent.document.getElementById('yourdiv');

Then do whatever you want with that div.

So far the answers didn't help me as I have a button and a textInput field (side by side) below the textView which kept getting hidden by the keyboard, but this has solved my issue:

android:windowSoftInputMode="adjustResize"

That's Oracle specific notation for an OUTER JOIN, because the ANSI-89 format (using a comma in the FROM clause to separate table references) didn't standardize OUTER joins.

The query would be re-written in ANSI-92 syntax as:

   SELECT ...
     FROM a
LEFT JOIN b ON b.id = a.id

This link is pretty good at explaining the difference between JOINs.

It should also be noted that even though the (+) works, Oracle recommends not using it:

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions, which do not apply to the FROM clause OUTER JOIN syntax:

From dialog to activity that you want to refresh. If it not first activity!
Like this:mainActivity>>objectActivity>>dialog
In your dialog class:

  @Override
public void dismiss() {
    super.dismiss();
   getActivity().finish();
    Intent i = new Intent(getActivity(), objectActivity.class);  //your class
    startActivity(i);

}

I had the following configuration in my httpd.conf that denied executing the wpadmin/setup-config.php file from wordpress. Removing the |-config part solved the problem. I think this httpd.conf is from plesk but it could be some default suggested config from wordpress, i don't know. Anyway, I could safely add it back after the setup finished.

<LocationMatch "(?i:(?:wp-config\\.bak|\\.wp-config\\.php\\.swp|(?:readme|license|changelog|-config|-sample)\\.(?:php|md|txt|htm|html)))">
                        Require all denied
                </LocationMatch>

A better solution (mentioned by @KrisNuttycombe):

git diff fc17405...ee2de56

for the merge commit:

commit 0e1329e551a5700614a2a34d8101e92fd9f2cad6 (HEAD, master)
Merge: fc17405 ee2de56
Author: Tilman Vogel <email@email>
Date:   Tue Feb 22 00:27:17 2011 +0100

to show all of the changes on ee2de56 that are reachable from commits on fc17405. Note the order of the commit hashes - it's the same as shown in the merge info: Merge: fc17405 ee2de56

Also note the 3 dots ... instead of two!

For a list of changed files, you can use:

git diff fc17405...ee2de56 --name-only

You are floating the children which means they "float" in front of the container. In order to take the correct height, you must "clear" the float

The div style="clear: both" clears the floating an gives the correct height to the container. see http://css.maxdesign.com.au/floatutorial/clear.htm for more info on floats.

eg.

<div class="c">
    <div class="l">

    </div>
    <div class="m">
        World
    </div>
    <div style="clear: both" />
</div>

If you give the label an ID, like this:

<label for="foo" id="foo_label">

Then this would work:

#foo_label { display: none;}

Your other options aren't really cross-browser friendly, unless javascript is an option. The CSS3 selector, not as widely supported looks like this:

[for="foo"] { display: none;}

It may have been covered elsewhere but simply changing the encoding line of the XML source to 'utf-16' allows the XML to be inserted into a SQL Server 'xml'data type.

using (DataSetTableAdapters.SQSTableAdapter tbl_SQS = new DataSetTableAdapters.SQSTableAdapter())
{
    try
    {
        bodyXML = @"<?xml version="1.0" encoding="UTF-8" standalone="yes"?><test></test>";
        bodyXMLutf16 = bodyXML.Replace("UTF-8", "UTF-16");
        tbl_SQS.Insert(messageID, receiptHandle, md5OfBody, bodyXMLutf16, sourceType);
    }
    catch (System.Data.SqlClient.SqlException ex)
    {
        Console.WriteLine(ex.Message);
        Console.ReadLine();
    }
}

The result is all of the XML text is inserted into the 'xml' data type field but the 'header' line is removed. What you see in the resulting record is just

<test></test>

Using the serialization method described in the "Answered" entry is a way of including the original header in the target field but the result is that the remaining XML text is enclosed in an XML <string></string> tag.

The table adapter in the code is a class automatically built using the Visual Studio 2013 "Add New Data Source: wizard. The five parameters to the Insert method map to fields in a SQL Server table.

A simple intuitive implementation:

public static List<PointF> RemoveDuplicates(List<PointF> listPoints)
{
    List<PointF> result = new List<PointF>();

    for (int i = 0; i < listPoints.Count; i++)
    {
        if (!result.Contains(listPoints[i]))
            result.Add(listPoints[i]);
        }

        return result;
    }

Test the return value of grep:

./somecommand | grep 'string' &> /dev/null
if [ $? == 0 ]; then
   echo "matched"
fi

which is done idiomatically like so:

if ./somecommand | grep -q 'string'; then
   echo "matched"
fi

and also:

./somecommand | grep -q 'string' && echo 'matched'

This is how I implemented it pre-material design and it seems to still work now I've switched to the new Toolbar. In my case I want to log the user in if they attempt to open the side nav while logged out, (and catch the event so the side nav won't open). In your case you could not return true;.

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (!isLoggedIn() && item.getItemId() == android.R.id.home) {
        login();
        return true;
    }
    return mDrawerToggle.onOptionsItemSelected(item) || super.onOptionsItemSelected(item);
}

I just had this issue, but only when I published to my website, on my local debug it ran fine. I found I had to use the FTP from my webhost and go into my publish dir and delete the files in the BIN folder, deleting them locally did nothing when I published.

Something like this? I haven't tested it, though:

select top 1 x
from (
  select top 2 distinct x 
  from y 
  order by x desc
) z
order by x

How about:

def ExtractAlphanumeric(InputString):
    from string import ascii_letters, digits
    return "".join([ch for ch in InputString if ch in (ascii_letters + digits)])

This works by using list comprehension to produce a list of the characters in InputString if they are present in the combined ascii_letters and digits strings. It then joins the list together into a string.

You can use karma-jasmine plugin to set the default time out interval globally.

Add this config in karma.conf.js

module.exports = function(config) {
  config.set({
    client: {
      jasmine: {
        timeoutInterval: 10000
      }
    }
  })
}

function refreshPage()
{

        transition: 'none',
        reloadPage: true
    });
}

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

IP addresses are part of the Network layer in the "seven-layer stack". The Network layer can do whatever it wants to do with the IP address. That's what happens with a proxy server, NAT, relay, or whatever.

The Application layer should not depend on the IP address in any way. In particular, an IP Address is not meant to be an identifier of anything other than the idenfitier of one end of a network connection. As soon as a connection is closed, you should expect the IP address (of the same user) to change.

Abstract function(method) :

? An abstract method is a method which is declared with the keyword abstract.

? It does not have body.

? It should be implemented by the derived class.

? If a method is abstract then the class should abstract.

virtual function(method) :

? A virtual method is the method which is declared with the keyword virtual and it can be overridden by the derived class method by using override keyword.

? It's up to the derived class whether to override it or not.

If your set command supports the /p switch, then you can pipe input that way.

set /p VAR1=<test.txt
set /? |find "/P"

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

This has the added benefit of working for un-registered file types (which the accepted answer does not).

If you want HTML, with images and a list, this isn't support by UILabel. However, I've found YYText does the trick.

Instead of using the block approach, which gave me some problems:

    IMP imp = [_controller methodForSelector:selector];
    void (*func)(id, SEL) = (void *)imp;

I will use NSInvocation, like this:

    -(void) sendSelectorToDelegate:(SEL) selector withSender:(UIButton *)button 

    if ([delegate respondsToSelector:selector])
    {
    NSMethodSignature * methodSignature = [[delegate class]
                                    instanceMethodSignatureForSelector:selector];
    NSInvocation * delegateInvocation = [NSInvocation
                                   invocationWithMethodSignature:methodSignature];


    [delegateInvocation setSelector:selector];
    [delegateInvocation setTarget:delegate];

    // remember the first two parameter are cmd and self
    [delegateInvocation setArgument:&button atIndex:2];
    [delegateInvocation invoke];
    }

Used the above code in MVC5 project and it works completely fine with the validation error. Just try this code:

   [Required]
   [Display(Name = "Email")]
   [EmailAddress]

   [RegularExpression(@"^([A-Za-z0-9][^'!&\\#*$%^?<>()+=:;`~\[\]{}|/,?€@ ][a-zA-z0- 
    9-._][^!&\\#*$%^?<>()+=:;`~\[\]{}|/,?€@ ]*\@[a-zA-Z0-9][^!&@\\#*$%^?<> 
        ()+=':;~`.\[\]{}|/,?€ ]*\.[a-zA-Z]{2,6})$", ErrorMessage = "Please enter a 
   valid Email")]


   public string ReceiverMail { get; set; }

You won't get real HTML rendering to <canvas> per se currently, because canvas context does not have functions to render HTML elements.

There are some emulations:

html2canvas project http://html2canvas.hertzen.com/index.html (basically a HTML renderer attempt built on Javascript + canvas)

HTML to SVG to <canvas> might be possible depending on your use case:

https://github.com/miohtama/Krusovice/blob/master/src/tools/html2svg2canvas.js

Also if you are using Firefox you can hack some extended permissions and then render a DOM window to <canvas>

https://developer.mozilla.org/en-US/docs/HTML/Canvas/Drawing_Graphics_with_Canvas?redirectlocale=en-US&redirectslug=Drawing_Graphics_with_Canvas#Rendering_Web_Content_Into_A_Canvas

You could just use a HashSet<String> to maintain a collection of unique objects. If the Integer values in your map are important, then you can instead use the containsKey method of maps to test whether your key is already in the map.

I was getting the same issue in windows. I fixed it by

• Downloading hadoop-common-2.2.0-bin-master from link.
• Create a user variable HADOOP_HOME in Environment variable and assign the path of hadoop-common bin directory as a value.
• You can verify it by running hadoop in cmd.
• Restart the IDE and Run it.

Just implemented my OWIN Service with Bearer (called access_token in the following) and Refresh Tokens. My insight into this is that you can use different flows. So it depends on the flow you want to use how you set your access_token and refresh_token expiration times.

I will describe two flows A and B in the follwing (I suggest what you want to have is flow B):

A) expiration time of access_token and refresh_token are the same as it is per default 1200 seconds or 20 minutes. This flow needs your client first to send client_id and client_secret with login data to get an access_token, refresh_token and expiration_time. With the refresh_token it is now possible to get a new access_token for 20 minutes (or whatever you set the AccessTokenExpireTimeSpan in the OAuthAuthorizationServerOptions to). For the reason that the expiration time of access_token and refresh_token are the same, your client is responsible to get a new access_token before the expiration time! E.g. your client could send a refresh POST call to your token endpoint with the body (remark: you should use https in production)

grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xxxxx

to get a new token after e.g. 19 minutes to prevent the tokens from expiration.

B) in this flow you want to have a short term expiration for your access_token and a long term expiration for your refresh_token. Lets assume for test purpose you set the access_token to expire in 10 seconds (AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(10)) and the refresh_token to 5 Minutes. Now it comes to the interesting part setting the expiration time of refresh_token: You do this in your createAsync function in SimpleRefreshTokenProvider class like this:

var guid = Guid.NewGuid().ToString();


        //copy properties and set the desired lifetime of refresh token
        var refreshTokenProperties = new AuthenticationProperties(context.Ticket.Properties.Dictionary)
        {
            IssuedUtc = context.Ticket.Properties.IssuedUtc,
            ExpiresUtc = DateTime.UtcNow.AddMinutes(5) //SET DATETIME to 5 Minutes
            //ExpiresUtc = DateTime.UtcNow.AddMonths(3) 
        };
        /*CREATE A NEW TICKET WITH EXPIRATION TIME OF 5 MINUTES 
         *INCLUDING THE VALUES OF THE CONTEXT TICKET: SO ALL WE 
         *DO HERE IS TO ADD THE PROPERTIES IssuedUtc and 
         *ExpiredUtc to the TICKET*/
        var refreshTokenTicket = new AuthenticationTicket(context.Ticket.Identity, refreshTokenProperties);

        //saving the new refreshTokenTicket to a local var of Type ConcurrentDictionary<string,AuthenticationTicket>
        // consider storing only the hash of the handle
        RefreshTokens.TryAdd(guid, refreshTokenTicket);            
        context.SetToken(guid);

Now your client is able to send a POST call with a refresh_token to your token endpoint when the access_token is expired. The body part of the call may look like this: grant_type=refresh_token&client_id=xxxxxx&refresh_token=xxxxxxxx-xxxx-xxxx-xxxx-xx

One important thing is that you may want to use this code not only in your CreateAsync function but also in your Create function. So you should consider to use your own function (e.g. called CreateTokenInternal) for the above code. Here you can find implementations of different flows including refresh_token flow(but without setting the expiration time of the refresh_token)

Here is one sample implementation of IAuthenticationTokenProvider on github (with setting the expiration time of the refresh_token)

I am sorry that I can't help out with further materials than the OAuth Specs and the Microsoft API Documentation. I would post the links here but my reputation doesn't let me post more than 2 links....

I hope this may help some others to spare time when trying to implement OAuth2.0 with refresh_token expiration time different to access_token expiration time. I couldn't find an example implementation on the web (except the one of thinktecture linked above) and it took me some hours of investigation until it worked for me.

New info: In my case I have two different possibilities to receive tokens. One is to receive a valid access_token. There I have to send a POST call with a String body in format application/x-www-form-urlencoded with the following data

client_id=YOURCLIENTID&grant_type=password&username=YOURUSERNAME&password=YOURPASSWORD

Second is if access_token is not valid anymore we can try the refresh_token by sending a POST call with a String body in format application/x-www-form-urlencoded with the following data grant_type=refresh_token&client_id=YOURCLIENTID&refresh_token=YOURREFRESHTOKENGUID

key = cv2.waitKey(1)

This is from the openCV package. It detects a keypress without waiting.

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

Try:

    fs.readFile("test.txt", "utf8", function(err, data) {...});

Basically, you need to specify the encoding.

Here is the solution to your problem! You just need to use this format:

<a href="https://api.whatsapp.com/send?phone=whatsappphonenumber&text=urlencodedtext"></a>

In the place of "urlencodedtext" you need to keep the content in Url-encode format.

UPDATE-- Use this from now(Nov-2018)

<a href="https://wa.me/whatsappphonenumber/?text=urlencodedtext"></a>

Use: https://wa.me/15551234567

Don't use: https://wa.me/+001-(555)1234567

To create your own link with a pre-filled message that will automatically appear in the text field of a chat, use https://wa.me/whatsappphonenumber/?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and URL-encodedtext is the URL-encoded pre-filled message.

Example:https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

To create a link with just a pre-filled message, use https://wa.me/?text=urlencodedtext

Example:https://wa.me/?text=I'm%20inquiring%20about%20the%20apartment%20listing

After clicking on the link, you will be shown a list of contacts you can send your message to.

For more information, see https://www.whatsapp.com/faq/en/general/26000030

This is basically the same approach as the answer by Box9 but I wrapped it in a nice jquery plugin that takes the same arguments as a regular animate, for when you need to have more animated parameters and get tired of repeating the same code over and over:

;(function($)
{
  $.fn.animateToAutoHeight = function(){
  var curHeight = this.css('height'),
      height = this.css('height','auto').height(),
      duration = 200,
      easing = 'swing',
      callback = $.noop,
      parameters = { height: height };
  this.css('height', curHeight);
  for (var i in arguments) {
    switch (typeof arguments[i]) {
      case 'object':
        parameters = arguments[i];
        parameters.height = height;
        break;
      case 'string':
        if (arguments[i] == 'slow' || arguments[i] == 'fast') duration = arguments[i];
        else easing = arguments[i];
        break;
      case 'number': duration = arguments[i]; break;
      case 'function': callback = arguments[i]; break;
    }
  }
  this.animate(parameters, duration, easing, function() {
    $(this).css('height', 'auto');
    callback.call(this, arguments);
  });
  return this;
  }
})(jQuery);

edit: chainable and cleaner now

<a class="btn btn-large btn-success" id="fire" href="http://twitter.github.io/bootstrap/examples/marketing-narrow.html#">Send Email</a>

$('#fire').on('click', function (e) {

     //your awesome code here

})

or alternatively you could not bother coding for it and use the 'conditional formatting' function in Excel which will set the background colour and font colour based on cell value.

There are only two variables here so set the default to yellow and then overwrite when the value is greater than or less than your threshold values.

This may be OT but if you are serializing a lot of primitive types or POD structures, Google Protocol Buffers for .Net might be useful to you. This addresses the endianness issue @Marc raised above, among other useful features.

If you are trying to get the id, then please update your code like

  html += '<option id = "' + n.id + "' value="' + i + '">' + n.names + '</option>';

To retrieve id,

$('option:selected').attr("id")

To retrieve Value

$('option:selected').val()

in Javascript

var e = document.getElementById("jobSel");
var job = e.options[e.selectedIndex].value;

I would approach it like this:

sizes = [100, 250] print "How much space should the random song list occupy?" print '\n'.join("{0}. {1}Mb".format(n, s)                 for n, s in enumerate(sizes, 1)) # present choices choice = int(raw_input("Enter choice:")) # throws error if not int size = sizes[0] # safe starting choice if choice in range(2, len(sizes) + 1):     size = sizes[choice - 1] # note index offset from choice print "You  want to create a random song list that is {0}Mb.".format(size) 

You could also loop until you get an acceptable answer and cover yourself in case of error:

choice = 0 while choice not in range(1, len(sizes) + 1): # loop     try: # guard against error         choice = int(raw_input(...))     except ValueError: # couldn't make an int         print "Please enter a number"         choice = 0 size = sizes[choice - 1] # now definitely valid 

grep has a -P switch allowing to use perl regexp syntax the perl regex allows to look at bytes, using \x.. syntax.

so you can look for a given hex string in a file with: grep -aP "\xdf"

but the outpt won't be very useful; indeed better do a regexp on the hexdump output;

The grep -P can be useful however to just find files matrching a given binary pattern. Or to do a binary query of a pattern that actually happens in text (see for example How to regexp CJK ideographs (in utf-8) )

Of course in PHP7.2

sudo apt-get install php7.2-dev

Go to the Eclipse base folder ? open eclipse.ini ? you will find the below line at line no 4:

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20150204-1316 plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120913-144807

As you can see, line 1 is of 64-bit Eclipse. It contains x86_64 and line 2 is of 32-bit Eclipse. It contains x_86.

For 32-bit Eclipse only x86 will be present and for 64-bit Eclipse x86_64 will be present.

Supporting ownership, maximum number of processes share lock and the maximum number of allowed processes/threads in critical section are three major factors that determine the name/type of the concurrent object with general name of lock. Since the value of these factors are binary (have two states), we can summarize them in a 3*8 truth-like table.

• X (Supports Ownership?): no(0) / yes(1)
• Y (#sharing processes): > 1 (8) / 1
• Z (#processes/threads in CA): > 1 (8) / 1

  X   Y   Z          Name
 --- --- --- ------------------------
  0   8   8   Semaphore              
  0   8   1   Binary Semaphore       
  0   1   8   SemaphoreSlim          
  0   1   1   Binary SemaphoreSlim(?)
  1   8   8   Recursive-Mutex(?)     
  1   8   1   Mutex                  
  1   1   8   N/A(?)                 
  1   1   1   Lock/Monitor           

Feel free to edit or expand this table, I've posted it as an ascii table to be editable:)

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

If you have imported the project, you may have to re-import it the proper way.
Steps :

1. Close Android Studio. Take backup of the project from C:\Users\UserName\AndroidStudioProjects\YourProject to some other folder . Now delete the project.
   
2. Launch Android Studio and click "Import Non-AndroidStudio Project (even if the project to be imported is an AndroidStudio project).
   
3. Select only the root folder of the project to be imported. Set the destination directory. Keep all the options checked. AndroidStudio will prompt to make some changes, click Ok for all prompts.
   
4. Now you can see the Module pre-defined at the top and you can launch the app to the emulator.
   
   

Tested on AndroidStudio version 1.0.1

Is there a way to convert an Integer[] array to an int[] array?

This gross omission from the Java core libraries seems to come up on pretty much every project I ever work on. And as convenient as the Trove library might be, I am unable to parse the precise requirements to meet LPGL for an Android app that statically links an LGPL library (preamble says ok, body does not seem to say the same). And it's just plain inconvenient to go rip-and-stripping Apache sources to get these classes. There has to be a better way.

The logic is simple. setOnClickListener belongs to step 2.

1. You create the button
2. You create an instance of OnClickListener* like it's done in that example and override the onClick-method.
3. You assign that OnClickListener to that button using btn.setOnClickListener(myOnClickListener); in your fragments/activities onCreate-method.
4. When the user clicks the button, the onClick function of the assigned OnClickListener is called.

*If you import android.view.View; you use View.OnClickListener. If you import android.view.View.*; or import android.view.View.OnClickListener; you use OnClickListener as far as I get it.

Another way is to let you activity/fragment inherit from OnClickListener. This way you assign your fragment/activity as the listener for your button and implement onClick as a member-function.

I did something simple, but it works.

I used a typical ToggleButton, which I restyled as a textblock by changing its control template. Then I just bound the IsChecked property on the ToggleButton to the IsOpen property on the popup. Popup has some properties like StaysOpen that let you modify the closing behavior.

The following works in XamlPad.

 <StackPanel>
  <ToggleButton Name="button"> 
    <ToggleButton.Template>
      <ControlTemplate TargetType="ToggleButton">
        <TextBlock>Click Me Here!!</TextBlock>
      </ControlTemplate>      
    </ToggleButton.Template>
  </ToggleButton>
  <Popup IsOpen="{Binding IsChecked, ElementName=button}" StaysOpen="False">
    <Border Background="LightYellow">
      <TextBlock>I'm the popup</TextBlock>
    </Border>
  </Popup> 
 </StackPanel>

my case was a little different - unintentionally I have changed owner of git repository (project.git directory in my case), changing owner back to the git user helped

Webpack configuration is being handled by react-scripts. You can find all webpack config inside node_modules react-scripts/config.

And If you want to customize webpack config, you can follow this customize-webpack-config

Have a look at qtlcharts. It allows you to create interactive correlation matrices:

library(qtlcharts)
data(iris)
iris$Species <- NULL
iplotCorr(iris, reorder=TRUE)

It's more impressive when you correlate more variables, like in the package's vignette:

I came across this issue when not using async/await on a asynchronous function (api call). Hence adding them / using the promise handlers properly cleared the error.

then use what group 2 captures...

A complete solution for anyone that might need it, I've used this with good results so far

JS:

$(".btn-popover-container").each(function() {
    var btn = $(this).children(".popover-btn");
    var titleContainer = $(this).children(".btn-popover-title");
    var contentContainer = $(this).children(".btn-popover-content");

    var title = $(titleContainer).html();
    var content = $(contentContainer).html();

    $(btn).popover({
        html: true,
        title: title,
        content: content,
        placement: 'right'
    });
});

HTML:

<div class="btn-popover-container">
    <button type="button" class="btn btn-link popover-btn">Button Name</button>
    <div class="btn-popover-title">
        Popover Title
    </div>
    <div class="btn-popover-content">
        <form>
          Or Other content..
        </form>
    </div>
</div>

CSS:

.btn-popover-container {
    display: inline-block;
}


.btn-popover-container .btn-popover-title, .btn-popover-container .btn-popover-content {
    display: none;
}

if you set your context model as code first based on exist database so you have to for set migration:

Add-Migration InitialCreate –IgnoreChanges
Update-database -force

and then change your context model and set:

Add-migration RemoveIspositive
Update-database -force

Just special-case it. If you see a numerator of 0 and a denominator of 0, pretend like it has the values you really want.

You need to add annotations to the Junit class, telling it to use the SpringJunitRunner. The ones you want are:

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)

This tells Junit to use the test-context.xml file in same directory as your test. This file should be similar to the real context.xml you're using for spring, but pointing to test resources, naturally.

Found the answer. What I did was was first

sudo apt-get install aptitude
sudo aptitude install libglib2.0-0
sudo aptitude install gcc-4.7 make linux-headers-`uname -r` -y

and tried it but it didn't work so I continued and did

sudo apt-get install build-essential
sudo apt-get install gcc-4.7 linux-headers-`uname -r`

after doing these two steps and trying again, it worked.

Here is the short answer:

$ ls -ld directory

Here's what it does:

-d, --directory
    list directory entries instead of contents, and do not dereference symbolic links

Try this code once-

public class FindPeopleFragment extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
      Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_home,
        container, false);
        Button button = (Button) rootView.findViewById(R.id.button1);
        button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        updateDetail();
        }
        });
        return rootView;
        }

public void updateDetail() {
        Intent intent = new Intent(getActivity(), MainActivityList.class);
        startActivity(intent);
        }
}

And as suggested by Raghunandan remove below code from your fragment_home.xml-

android:onClick="goToAttract"

Add &autoplay=1 to your syntax, like this

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/zGPuazETKkI&amp;autoplay=1" frameborder="0" allowfullscreen></iframe>

If the script only defines the functions and does nothing else, you can first execute the script within the context of the current shell using the source or . command and then simply call the function. See help source for more information.

This worked for me:

string="1;2"
echo $string | cut -d';' -f1 # output is 1
echo $string | cut -d';' -f2 # output is 2

This kind of functionality is built in.

When using a decimal you can use a format string "C" or "c".

decimal dec = 123.00M;
string uk = dec.ToString("C", new CultureInfo("en-GB")); // uk holds "£123.00"
string us = dec.ToString("C", new CultureInfo("en-US")); // us holds "$123.00"

I see the question has already been answered, but still want to add my 2 cents for the same.

I have also faced similar scenario in which I have to test the execution times for several approaches and hence written a small script, which calls timeit on all functions written in it.

The script is also available as github gist here.

Hope it will help you and others.

Easy install for ubuntu:

Just run:

sudo apt-get install php5-pgsql

then

sudo service apache2 restart //restart apache

or

Uncomment the following in php.ini by removing the ;

;extension=php_pgsql.dll

then restart apache

This is for future readers. I found that the simplest method for me was to use Visual Studio -> Tools -> External Tools. More details in this answer.

Easier to use and good debugging tools.

This will get what you want in plain JS.

var el = document.getElementById('*spaM4');
text = (el.innerText || el.textContent);

Try

 ThisWorkbook.Sheets("name of sheet 2").Range("A1")

to access a range in sheet 2 independently of where your code is or which sheet is currently active. To make sheet 2 the active sheet, try

 ThisWorkbook.Sheets("name of sheet 2").Activate

If you just need the sum of a row in a different sheet, there is no need for using VBA at all. Enter a formula like this in sheet 1:

=SUM([Name-Of-Sheet2]!A1:D1)

You need to begin the session at the top of a page or before you call session code

session_start(); 

I use the && expression which works perfectly for me.

For example,

<button ng-model="vm.slideOneValid" ng-disabled="!vm.slideOneValid" ng-click="vm.slideOneValid && vm.nextSlide()" class="btn btn-light-green btn-medium pull-right">Next</button>

If vm.slideOneValid is false, the second part of the expression is not fired. I know this is putting logic into the DOM, but it's a quick a dirty way to get ng-disabled and ng-click to place nice.

Just remember to add ng-model to the element to make ng-disabled work.

You could do this with partial application, although using named variables definitely leads to more readable code. John Resig wrote a blog article in 2008 about how to do it in JavaScript: http://ejohn.org/blog/partial-functions-in-javascript/

Function.prototype.partial = function(){
  var fn = this, args = Array.prototype.slice.call(arguments);
  return function(){
    var arg = 0;
    for ( var i = 0; i < args.length && arg < arguments.length; i++ )
      if ( args[i] === undefined )
        args[i] = arguments[arg++];
    return fn.apply(this, args);
  };
};

It would probably be possible to apply the same principle in Ruby (except for the prototypal inheritance).

This code snippet will auto size all the columns that contain data in all the sheets. There is no need to use the activeSheet getter and setter.

// In my case this line didn't make much of a difference
PHPExcel_Shared_Font::setAutoSizeMethod(PHPExcel_Shared_Font::AUTOSIZE_METHOD_EXACT);
// Iterating all the sheets
/** @var PHPExcel_Worksheet $sheet */
foreach ($objPHPExcel->getAllSheets() as $sheet) {
    // Iterating through all the columns
    // The after Z column problem is solved by using numeric columns; thanks to the columnIndexFromString method
    for ($col = 0; $col <= PHPExcel_Cell::columnIndexFromString($sheet->getHighestDataColumn()); $col++) {
        $sheet->getColumnDimensionByColumn($col)->setAutoSize(true);
    }
}

Here's how to implement this from the official page:

http://getbootstrap.com/2.3.2/examples/sticky-footer.html

I just tested it right now and it WORKS GREAT! :)

HTML

<body>

    <!-- Part 1: Wrap all page content here -->
    <div id="wrap">

      <!-- Begin page content -->
      <div class="container">
        <div class="page-header">
          <h1>Sticky footer</h1>
        </div>
        <p class="lead">Pin a fixed-height footer to the bottom of the viewport in desktop browsers with this custom HTML and CSS.</p>
      </div>

      <div id="push"></div>
    </div>

    <div id="footer">
      <div class="container">
        <p class="muted credit">Example courtesy <a href="http://martinbean.co.uk">Martin Bean</a> and <a href="http://ryanfait.com/sticky-footer/">Ryan Fait</a>.</p>
      </div>
    </div>
</body>

The relevant CSS code is this:

/* Sticky footer styles
-------------------------------------------------- */
html,
body {
    height: 100%;
    /* The html and body elements cannot have any padding or margin. */
}

/* Wrapper for page content to push down footer */
#wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    /* Negative indent footer by it's height */
    margin: 0 auto -30px;
}

/* Set the fixed height of the footer here */
#push,
#footer {
    height: 30px;
}

#footer {
    background-color: #f5f5f5;
}

/* Lastly, apply responsive CSS fixes as necessary */
@media (max-width: 767px) {
    #footer {
        margin-left: -20px;
        margin-right: -20px;
        padding-left: 20px;
        padding-right: 20px;
    }
}
