Abie, it all comes down to your use case. Rather than relying on someone else's account of their use case, feel free to post your use case to the rabbitmq-discuss list. Asking on twitter will get you some responses too. Best wishes, alexis

It looks like you are trying to use (almost) straight up C code here. Go has a few differences.

• First off, you can't initialize arrays and slices as const. The term const has a different meaning in Go, as it does in C. The list should be defined as var instead.
• Secondly, as a style rule, Go prefers basenameOpts as opposed to basename_opts.
• There is no char type in Go. You probably want byte (or rune if you intend to allow unicode codepoints).
• The declaration of the list must have the assignment operator in this case. E.g.: var x = foo.
• Go's parser requires that each element in a list declaration ends with a comma. This includes the last element. The reason for this is because Go automatically inserts semi-colons where needed. And this requires somewhat stricter syntax in order to work.

For example:

type opt struct {
    shortnm      byte
    longnm, help string
    needArg      bool
}

var basenameOpts = []opt { 
    opt {
        shortnm: 'a', 
        longnm: "multiple", 
        needArg: false, 
        help: "Usage for a",
    },
    opt {
        shortnm: 'b', 
        longnm: "b-option", 
        needArg: false, 
        help: "Usage for b",
    },
}

An alternative is to declare the list with its type and then use an init function to fill it up. This is mostly useful if you intend to use values returned by functions in the data structure. init functions are run when the program is being initialized and are guaranteed to finish before main is executed. You can have multiple init functions in a package, or even in the same source file.

    type opt struct {
        shortnm      byte
        longnm, help string
        needArg      bool
    }

    var basenameOpts []opt

    func init() { 
        basenameOpts = []opt{
            opt {
                shortnm: 'a', 
                longnm: "multiple", 
                needArg: false, 
                help: "Usage for a",
            },
            opt {
                shortnm: 'b', 
                longnm: "b-option", 
                needArg: false, 
               help: "Usage for b",
            },
        }
    }

Since you are new to Go, I strongly recommend reading through the language specification. It is pretty short and very clearly written. It will clear a lot of these little idiosyncrasies up for you.

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Sub openwb()
Dim wkbk As Workbook
Dim NewFile As Variant

NewFile = Application.GetOpenFilename("microsoft excel files (*.xlsm*), *.xlsm*")

If NewFile <> False Then
Set wkbk = Workbooks.Open(NewFile)
End If
End Sub

Try this .... I got it... onClientClick="var b=validateView();if(b) var b=ShowDiv1();return b;"

Not quite, although generally you can usually use some workaround on one of the forms

• [^abc], which is character by character not a or b or c,
• or negative lookahead: a(?!b), which is a not followed by b
• or negative lookbehind: (?<!a)b, which is b not preceeded by a

There is also a very helpful GUI tool called Product Browser which appears to be made by Microsoft or at least an employee of Microsoft.

It can be found on Github here Product Browser

I personally had a very easy time locating the GUID I needed with this.

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

Use the DropDownClosed event instead of selectionChanged if you want the current value of the combo box.

private void comboBox_DropDownClosed(object sender, EventArgs e)
{
   MessageBox.Show(comboBox.Text) 
}

Is really that simple.

Add .idea and *.iml to .gitignore, you don't need those files to successfully import and compile the project.

If you merged the branch, then reverted the merge using a pull request and merged that pull request to revert.

The easiest way I felt was to:

1. Take out a new branch from develop/master (where you merged)
2. Revert the "revert" using git revert -m 1 xxxxxx (if the revert was merged using a branch) or using git revert xxxxxx if it was a simple revert
3. The new branch should now have the changes you want to merge again.
4. Make changes or merge this branch to develop/master

Aren't enums best choice for these kinds of stuff?

Using PowerShell, you can use the following

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Select name

This will show a list off all services which displayname starts with "NATION-".

You can also directly stop or start the services;

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Stop-Service
Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Start-Service

or simply

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Restart-Service

You can compare two String by using this.

Collections.sort(contactsList, new Comparator<ContactsData>() {

                    @Override
                    public int compare(ContactsData lhs, ContactsData rhs) {

                        char l = Character.toUpperCase(lhs.name.charAt(0));

                        if (l < 'A' || l > 'Z')

                            l += 'Z';

                        char r = Character.toUpperCase(rhs.name.charAt(0));

                        if (r < 'A' || r > 'Z')

                            r += 'Z';

                        String s1 = l + lhs.name.substring(1);

                        String s2 = r + rhs.name.substring(1);

                        return s1.compareTo(s2);

                    }

                });

And Now make a ContactData Class.

public class ContactsData {

public String name;
public String id;
public String email;
public String avatar; 
public String connection_type;
public String thumb;
public String small;
public String first_name;
public String last_name;
public String no_of_user;
public int grpIndex;

public ContactsData(String name, String id, String email, String avatar, String connection_type)
{
    this.name = name;
    this.id = id;
    this.email = email;
    this.avatar = avatar;
    this.connection_type = connection_type;

}
}

Here contactsList is :

public static ArrayList<ContactsData> contactsList = new ArrayList<ContactsData>();

Try this solution:

There is a data item in your table whose associated value doesn't exist in the table you want to use it as a primary key table. Make your table empty or add the associated value to the second table.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

Sorry, to rehash an old question, but this was the first Stack Overflow question/answer that popped up on Google.

This post (which came up first on Google) talks about using the more updated syntax for PostgreSQL 10: https://blog.2ndquadrant.com/postgresql-10-identity-columns/

which happens to be:

CREATE TABLE test_new (
    id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
);

Hope that helps :)

EditorFor works with metadata, so if you want to add html attributes you could always do it. Another option is to simply write a custom template and use TextBoxFor:

<%= Html.TextBoxFor(model => model.Control.PeriodType, 
    new { disabled = "disabled", @readonly = "readonly" }) %>    

I have started using inputmode="decimal" which works flawlessly with smartphones:

<input type="text" inputmode="decimal" value="1.5">

Note that we have to use type="text" instead of number. However, on desktop it still allows letters as values.

For desktop you could use:

<input type="number" inputmode="decimal">

which allows 0-9 and . as input and only numbers.

Note that some countries use , as decimal dividor which is activated as default on the NumPad. Thus entering a float number by Numpad would not work as the input field expects a . (in Chrome). That's why you should use type="text" if you have international users on your website.

You can try this on desktop (also with Numpad) and your phone:

<p>Input with type text:</p>
<input type="text" inputmode="decimal" value="1.5">
<br>
<p>Input with type number:</p>
<input type="number" inputmode="decimal" value="1.5">

it may be that your firewalls are preventing you from accessing the localhost's webserver.
Put the IP addresses of both of your computers' internet security antivirus network security as safe IP addresses if required.
How to find the IP address of your windows PC: Start > (Run) type in: cmd (Enter)
(This opens the black box command prompt)
type in ipconfig (Enter)
Let's say your Apache or IIS webserver is installed on your PC: 192.168.0.3
and you want to access your webserver with your laptop. (laptop's IP is 192.168.0.5)
On your PC you type in: http://localhost/ inside your Firefox or Internet Eplorer browser to access your data on your webserver.
On your laptop you type in http://192.168.0.3/ to access your webserver on your PC.

For all these things to work you need have installed a webserver correctly (e.g. IIS, Apache, XAMP, WAMP etc).

If it does not work, try to ping your PC from your laptop:
Open up command propmt on your laptop: Start > cmd (Enter)
ping 192.168.1.3 (Enter)
If the pinging fails, then firewalls are blocking your connection or your network cabling is faulty. Restart your modem or network switch and your machines.
Close programs such as chat programs that are using your ports.
You can also try a diffrent port number: http:192.168.0.3:80 or http:192.168.0.3:81 or any random number at the end

Markus has one way to avoid using the word for -- here's another, which should have much better performance for long the_lists...:

import itertools
found = any(itertools.ifilter(lambda x:x[1]=='b', the_list)

Try something like:

 SELECT id, NewsHeadline as news_headline, NewsText as news_text, state CreatedDate as created_on
 FROM News 
 WHERE CreatedDate >= DATEADD(day,-7, GETDATE())

If you want to use numpy only:

x = [-1, 2, 1, 3, 3]
vals,counts = np.unique(x, return_counts=True)

gives

(array([-1,  1,  2,  3]), array([1, 1, 1, 2]))

And extract it:

index = np.argmax(counts)
return vals[index]

Mac OS X users

I achieved this by enabling remote management:

• Ensure that your phone and laptop are connected to the same WiFi network
• On Mac, go to System preferences/sharing
• Enable remote management

You will see a message similar to this:

• Other users can manage your computer using the address some.url.com

On your Android device, you should now be able to go to some.url.com, which delegates to localhost on your Mac. You can also use ifconfig to get the IP address of your Mac.

Portable solution with ngrok (any OS with Node.js)

If you don't mind exposing your project with a temporary domain you can use ngrok. Lets say I have an app that runs on localhost:9460 I can simply write

npm install ngrok -g

ngrok http 9460

This will give me:

Session Status                online
Update                        update available (version 2.2.8, Ctrl-U to update)

I can now reach https://f7c23d14.ngrok.io as a way to remotely view localhost. This is great to share design work or progress with clients.

Alternate solution with nginx proxy pass

If you are running something like this through nginx proxy_pass it will require a bit more tweaking - this is a hacky approach, but it works for me and I am open to suggestions on improving it:

• Enable remote management (as mentioned above)
• Temporarily set the server to listen on port 81 as opposed to 80
• Type in the following command:

sudo nginx -s reload

• Visit http://youripaddress:81

server {
  listen 80;
  listen 81;   # <-------- add this to expose the app on a unique port
  server_name  ~^(local|local\.m).example.com$;
  # ...
}

Reload and visit http://youripaddress:81

You can do this in-place, rather than create a new dict, which may be preferable for large dictionaries (if you do not need a copy).

def mutate_dict(f,d):
    for k, v in d.iteritems():
        d[k] = f(v)

my_dictionary = {'a':1, 'b':2}
mutate_dict(lambda x: x+1, my_dictionary)

results in my_dictionary containing:

{'a': 2, 'b': 3}

With AWS Console

Use AWS Cloudwatch's metrics

With AWS CLI

Number of objects:

or:

aws s3api list-objects --bucket <BUCKET_NAME> --prefix "<FOLDER_NAME>" | wc -l

or:

aws s3 ls s3://<BUCKET_NAME>/<FOLDER_NAME>/ --recursive --summarize --human-readable | grep "Total Objects"

or with s4cmd:

s4cmd ls -r s3://<BUCKET_NAME>/<FOLDER_NAME>/ | wc -l

Objects size:

aws s3api list-objects --bucket <BUCKET_NAME> --output json --query "[sum(Contents[].Size), length(Contents[])]" | awk  'NR!=2 {print $0;next}  NR==2 {print $0/1024/1024/1024" GB"}'

or:

aws s3 ls s3://<BUCKET_NAME>/<FOLDER_NAME>/ --recursive --summarize --human-readable | grep "Total Size"

or with s4cmd:

s4cmd du s3://<BUCKET_NAME>

or with CloudWatch metrics:

aws cloudwatch get-metric-statistics --metric-name BucketSizeBytes --namespace AWS/S3 --start-time 2020-10-20T16:00:00Z --end-time 2020-10-22T17:00:00Z --period 3600 --statistics Average --unit Bytes --dimensions Name=BucketName,Value=<BUCKET_NAME> Name=StorageType,Value=StandardStorage --output json | grep "Average"

Another solution, based on scroll listener. Initial conditions are the same as in Sevastyan answer

RecyclerView recyclerView;
TextView tvTitle; //sticky header view

//... onCreate, initialize, etc...

public void bindList(List<Item> items) { //All data in adapter. Item - just interface for different item types
    adapter = new YourAdapter(items);
    recyclerView.setAdapter(adapter);
    StickyHeaderViewManager<HeaderItem> stickyHeaderViewManager = new StickyHeaderViewManager<>(
            tvTitle,
            recyclerView,
            HeaderItem.class, //HeaderItem - subclass of Item, used to detect headers in list
            data -> { // bind function for sticky header view
                tvTitle.setText(data.getTitle());
            });
    stickyHeaderViewManager.attach(items);
}

Layout for ViewHolder and sticky header.

item_header.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tv_title"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Layout for RecyclerView

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <!--it can be any view, but order important, draw over recyclerView-->
    <include
        layout="@layout/item_header"/>

</FrameLayout>

Class for HeaderItem.

public class HeaderItem implements Item {

    private String title;

    public HeaderItem(String title) {
        this.title = title;
    }

    public String getTitle() {
        return title;
    }

}

It's all use. The implementation of the adapter, ViewHolder and other things, is not interesting for us.

Mono comes with a wrapper, use theirs!

https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.

This seems the thinnest of all worlds, minimizing your dependence on third party libraries. If I had to do this project from scratch, this is the way I would do it.

You may have several php.ini files, one for CLI and one for apache. Run php --ini to see where the CLI ini location is.

Something like:

library(dplyr)

df <- data.frame(id=c(1,1,1,2,2,2,3,3,3),
                 stopId=c("a","b","c","a","b","c","a","b","c"),
                 stopSequence=c(1,2,3,3,1,4,3,1,2))

first_last <- function(x) {
  bind_rows(slice(x, 1), slice(x, n()))
}

df %>%
  group_by(id) %>%
  arrange(stopSequence) %>%
  do(first_last(.)) %>%
  ungroup

## Source: local data frame [6 x 3]
## 
##   id stopId stopSequence
## 1  1      a            1
## 2  1      c            3
## 3  2      b            1
## 4  2      c            4
## 5  3      b            1
## 6  3      a            3

With do you can pretty much perform any number of operations on the group but @jeremycg's answer is way more appropriate for just this task.

I like to use such static methods:

$result = $purchases_repository->matching(
    Criteria::create()->where(
        Criteria::expr()->gt('prize', 200)
    )
);

Of course, you can push logic when it is 1 condition, but when you have more conditions it is better to divide it into fragments, configure and pass it to the method:

If you are having problem regarding calling Web Service in android then You can use below code to call the web service and get response. Make sure that your the web service return the response in Data Table Format..This code will help you if you using data from SQL Server database. If you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement

void callWebService(){ 

private static final String NAMESPACE = "http://tempuri.org/"; // for wsdl it may be package name i.e http://package_name
private static final String URL = "http://localhost/sample/services/MyService?wsdl";
// you can use IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = "urn:" + METHOD_NAME;

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty("parm_name", prm_value);// Parameter for Method
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;// **If your Webservice in .net otherwise remove it**
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);// call the eb service
                                                                                                         // Method
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Next task is to get Response and format that response
    SoapObject obj, obj1, obj2, obj3;
    obj = (SoapObject) envelope.getResponse();
    obj1 = (SoapObject) obj.getProperty("diffgram");
    obj2 = (SoapObject) obj1.getProperty("NewDataSet");

    for (int i = 0; i < obj2.getPropertyCount(); i++) { 
// the method getPropertyCount() and  return the number of rows
            obj3 = (SoapObject) obj2.getProperty(i);
            obj3.getProperty(0).toString();// value of column 1
            obj3.getProperty(1).toString();// value of column 2
            // like that you will get value from each column
        }
    }

If you have any problem regarding this you can write me..

grep

Forgetting performance, this is POSIX and looks nicer than case solutions:

mystr="abcd"
if printf '%s' "$mystr" | grep -Eq '^ab'; then
  echo matches
fi

Explanation:

• printf '%s' to prevent printf from expanding backslash escapes: Bash printf literal verbatim string
• grep -q prevents echo of matches to stdout: How to check if a file contains a specific string using Bash
• grep -E enables extended regular expressions, which we need for the ^

Thank you for all answers! I found it! It calls "Column selection (for Sublime)" and "Column Mode Editing (for Notepad++)" https://www.sublimetext.com/docs/3/column_selection.html

Here is a simple answer. Hope it helps someone.

import org.springframework.boot.devtools.remote.client.HttpHeaderInterceptor;
import org.springframework.http.MediaType;
import org.springframework.http.client.ClientHttpRequestInterceptor;
import org.springframework.web.client.RestTemplate;


public String post(SomeRequest someRequest) {
    // create a list the headers 
    List<ClientHttpRequestInterceptor> interceptors = new ArrayList<>();
    interceptors.add(new HttpHeaderInterceptor("Accept", MediaType.APPLICATION_JSON_VALUE));
    interceptors.add(new HttpHeaderInterceptor("ContentType", MediaType.APPLICATION_JSON_VALUE));
    interceptors.add(new HttpHeaderInterceptor("username", "user123"));
    interceptors.add(new HttpHeaderInterceptor("customHeader1", "c1"));
    interceptors.add(new HttpHeaderInterceptor("customHeader2", "c2"));
    // initialize RestTemplate
    RestTemplate restTemplate = new RestTemplate();
    // set header interceptors here
    restTemplate.setInterceptors(interceptors);
    // post the request. The response should be JSON string
    String response = restTemplate.postForObject(Url, someRequest, String.class);
    return response;
}

The annotation @JoinColumn indicates that this entity is the owner of the relationship (that is: the corresponding table has a column with a foreign key to the referenced table), whereas the attribute mappedBy indicates that the entity in this side is the inverse of the relationship, and the owner resides in the "other" entity. This also means that you can access the other table from the class which you've annotated with "mappedBy" (fully bidirectional relationship).

In particular, for the code in the question the correct annotations would look like this:

@Entity
public class Company {
    @OneToMany(mappedBy = "company",
               orphanRemoval = true,
               fetch = FetchType.LAZY,
               cascade = CascadeType.ALL)
    private List<Branch> branches;
}

@Entity
public class Branch {
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "companyId")
    private Company company;
}

Encapsulation:

Hiding something, sort of like medicine capsule. We don't know what is in the capsule, we just take it. Same as in programming - we just hide some special code of method or property and it only gives output, same as capsule. In short, encapsulation hides data.

Abstraction:

Abstraction means hiding logic or implementation. For example, we take tablets and see their color and but don't know what is the purpose of this and how it works with the body.

All of the example above should work just add a document ready action and change the order of how you perform the updates to the texts, also make sure your using Script manager alternatively non of this will work for you. Here is the text within the code behind.

aspx

<div class="modal fade" id="myModal" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">

                </ContentTemplate>
            </asp:UpdatePanel>
        </div>
    </div>

Code Behind

lblModalTitle.Text = "Validation Errors";
lblModalBody.Text = form.Error;
upModal.Update();
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "myModal", "$(document).ready(function () {$('#myModal').modal();});", true);

Just wanted to add a couple of pence to the excellent answers above: If you are working on pre Extjs 4.1, and don't have application wide events but need them, I've been using a very simple technique that might help: Create a simple object extending Observable, and define any app wide events you might need in it. You can then fire those events from anywhere in your app, including actual html dom element and listen to them from any component by relaying the required elements from that component.

Ext.define('Lib.MessageBus', {
    extend: 'Ext.util.Observable',

    constructor: function() {
        this.addEvents(
            /*
             * describe the event
             */
                  "eventname"

            );
        this.callParent(arguments);
    }
});

Then you can, from any other component:

 this.relayEvents(MesageBus, ['event1', 'event2'])

And fire them from any component or dom element:

 MessageBus.fireEvent('event1', somearg);

 <input type="button onclick="MessageBus.fireEvent('event2', 'somearg')">

That's a lot of work for:

public static int byteArrayToLeInt(byte[] b) {
    final ByteBuffer bb = ByteBuffer.wrap(b);
    bb.order(ByteOrder.LITTLE_ENDIAN);
    return bb.getInt();
}

public static byte[] leIntToByteArray(int i) {
    final ByteBuffer bb = ByteBuffer.allocate(Integer.SIZE / Byte.SIZE);
    bb.order(ByteOrder.LITTLE_ENDIAN);
    bb.putInt(i);
    return bb.array();
}

This method uses the Java ByteBuffer and ByteOrder functionality in the java.nio package. This code should be preferred where readability is required. It should also be very easy to remember.

I've shown Little Endian byte order here. To create a Big Endian version you can simply leave out the call to order(ByteOrder).

In code where performance is higher priority than readability (about 10x as fast):

public static int byteArrayToLeInt(byte[] encodedValue) {
    int value = (encodedValue[3] << (Byte.SIZE * 3));
    value |= (encodedValue[2] & 0xFF) << (Byte.SIZE * 2);
    value |= (encodedValue[1] & 0xFF) << (Byte.SIZE * 1);
    value |= (encodedValue[0] & 0xFF);
    return value;
}

public static byte[] leIntToByteArray(int value) {
    byte[] encodedValue = new byte[Integer.SIZE / Byte.SIZE];
    encodedValue[3] = (byte) (value >> Byte.SIZE * 3);
    encodedValue[2] = (byte) (value >> Byte.SIZE * 2);   
    encodedValue[1] = (byte) (value >> Byte.SIZE);   
    encodedValue[0] = (byte) value;
    return encodedValue;
}

Just reverse the byte array index to count from zero to three to create a Big Endian version of this code.

Notes:

• In Java 8 you can also make use of the Integer.BYTES constant, which is more succinct than Integer.SIZE / Byte.SIZE.

to set a div at position fixed you can use

position:fixed
top:0;
left:0;
width:100%;
height:50px; /* change me */

In an SQL query, if the inner query executes for every row of the outer query. If the inner query is executed for once and the result is consumed by the outer query, then it is called as non co-related query.

Correlated sub-queries usually correspond to normal join queries, i.e. join queries that have no sub-queries, and can usually be expressed as such. It is sometimes recommended that they are translated into such join queries, because most SQL DBMSs will execute them .....

A null pointer exception is an indicator that you are using an object without initializing it.

For example, below is a student class which will use it in our code.

public class Student {

    private int id;

    public int getId() {
        return this.id;
    }

    public setId(int newId) {
        this.id = newId;
    }
}

The below code gives you a null pointer exception.

public class School {

    Student student;

    public School() {
        try {
            student.getId();
        }
        catch(Exception e) {
            System.out.println("Null pointer exception");
        }
    }
}

Because you are using student, but you forgot to initialize it like in the correct code shown below:

public class School {

    Student student;

    public School() {
        try {
            student = new Student();
            student.setId(12);
            student.getId();
        }
        catch(Exception e) {
            System.out.println("Null pointer exception");
        }
    }
}

I wanted to add a gradient to a view, and then anchor it using auto-layout.

    class GradientView: UIView {

    private let gradient: CAGradientLayer = {
        let layer = CAGradientLayer()
        let topColor: UIColor = UIColor(red:0.98, green:0.96, blue:0.93, alpha:0.5)
        let bottomColor: UIColor = UIColor.white
        layer.colors = [topColor.cgColor, bottomColor.cgColor]
        layer.locations = [0,1]
        return layer
    }()

    init() {
        super.init(frame: .zero)
        gradient.frame = frame
        layer.insertSublayer(gradient, at: 0)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        gradient.frame = bounds

    }
}

I had the same problem. It's a simple problem of not specifying the right path.

Right click on the on your .fxml file and select properties (for those using eclipse won't differ that much for another IDE) and then copy the copy the location starting from /packagename till the end and that should solve the problem

If you are using Http Client version 4.3 and above you should be using this:

RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(30 * 1000).build();
HttpClient httpClient = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build();

Examples of jersey Rest client :
Adding dependency :

         <!-- jersey -->
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.8</version>
    </dependency>
   <dependency>
        <groupId>com.sun.jersey</groupId>

ForGetMethod and passing two parameter :

          Client client = Client.create();
           WebResource webResource1 = client
                        .resource("http://localhost:10102/NewsTickerServices/AddGroup/"
                                + userN + "/" + groupName);

                ClientResponse response1 = webResource1.get(ClientResponse.class);
                System.out.println("responser is" + response1);

GetMethod passing one parameter and Getting a Respone of List :

       Client client = Client.create();

        WebResource webResource1 = client
                    .resource("http://localhost:10102/NewsTickerServices/GetAssignedUser/"+grpName);    
    //value changed
    String response1 = webResource1.type(MediaType.APPLICATION_JSON).get(String.class);

    List <String > Assignedlist =new ArrayList<String>();
     JSONArray jsonArr2 =new JSONArray(response1);
    for (int i =0;i<jsonArr2.length();i++){

        Assignedlist.add(jsonArr2.getString(i));    
    }

In Above It Returns a List which we are accepting as a List and then converting it to Json Array and then Json Array to List .

If Post Request passing Json Object as Parameter :

   Client client = Client.create();
    WebResource webResource = client
            .resource("http://localhost:10102/NewsTickerServices/CreateJUser");
    // value added

    ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).post(ClientResponse.class,mapper.writeValueAsString(user));

    if (response.getStatus() == 500) {

        context.addMessage(null, new FacesMessage("User already exist "));
    }

Here's another option that's longer but may be more readable:

Boolean(Number("0")); // false
Boolean(Number("1")); // true

If the trick using position:absolute, position:relative and top/left/bottom/right: 0px is not appropriate for your situation, you could try:

#nav {
    height: inherit;
}

This worked on one of our pages, although I am not sure exactly what other conditions were needed for it to succeed!

You only have to get the view of activity that carry this fragment and this could only happen when your fragment is already created

override the onViewCreated() method inside your fragment and enjoy its magic :) ..

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Button button = (Button) view.findViewById(R.id.YOURBUTTONID);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
         //place your action here
         }
    });

Hope this could help you ;

As of October 2014:

For latest remote version:

npm view <module_name> version  

Note, version is singular.

If you'd like to see all available (remote) versions, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

To get the version you actually have locally you could use:

npm list --depth=0 | grep <module_name>

Note, even with package.json declaring your versions, the installed version might actually differ slightly - for instance if tilda was used in the version declaration

Should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

DateTime2 wreaks havoc if you are an Access developer trying to write Now() to the field in question. Just did an Access -> SQL 2008 R2 migration and it put all the datetime fields in as DateTime2. Appending a record with Now() as the value bombed out. It was okay on 1/1/2012 2:53:04 PM, but not on 1/10/2012 2:53:04 PM.

Once character made the difference. Hope it helps somebody.

The severity level 16 in your example code is typically used for user-defined (user-detected) errors. The SQL Server DBMS itself emits severity levels (and error messages) for problems it detects, both more severe (higher numbers) and less so (lower numbers).

The state should be an integer between 0 and 255 (negative values will give an error), but the choice is basically the programmer's. It is useful to put different state values if the same error message for user-defined error will be raised in different locations, e.g. if the debugging/troubleshooting of problems will be assisted by having an extra indication of where the error occurred.

list = [1, 2, 3, 4, 5]
for i in list[0:-1]:
    print(i, end=', ')
print(list[-1])

do for loops really take that much longer to run?

was trying to make something that printed all str values in a list separated by commas, inserting "and" before the last entry and came up with this:

spam = ['apples', 'bananas', 'tofu', 'cats']
for i in spam[0:-1]:
    print(i, end=', ')
print('and ' + spam[-1])

Even after all these time, it might help someone. This is simple JS solution.

JS

  let date = new Date();
  let today = date.toISOString().substr(0, 10);
  //console.log("Today: ", today);//test
  document.getElementById("form-container").innerHTML =
    '<input type="date" name="myDate" value="' + today + '" >';//inject field

HTML

 <form id="form-container"></form>

Similar solution works in Angular without any additional library to convert date format. For Angular (code is shortened due to common component code):

//so in myComponent.ts 
//Import.... @Component...etc...
date: Date = new Date();
today: String; //<- note String
//more const ...
export class MyComponent implements OnInit {
   //constructor, etc.... 
   ngOnInit() {
      this.today = this.date.toISOString().substr(0, 10);
   }
}
//so in component.html 
<input type="date" [(ngModel)]="today"  />

There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.

If you have a long running background work you should specify this by using the correct Task Option.

You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

For Translating the command to python refer below:-

1)Alternative of cat command is open refer this. Below is the sample

>>> f = open('workfile', 'r')
>>> print f

2)Alternative of grep command refer this

3)Alternative of Cut command refer this

• The first danger lies in reload(sys).

  When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:

  (This is IPython shell)
  
  In [1]: import sys
  
  In [2]: sys.stdout
  Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
  
  In [3]: reload(sys)
  <module 'sys' (built-in)>
  
  In [4]: sys.stdout
  Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
  
  In [11]: import IPython.terminal
  
  In [14]: IPython.terminal.interactiveshell.sys.stdout
  Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
  

• Now, sys.setdefaultencoding() proper

  All that it affects is implicit conversion str<->unicode. Now, utf-8 is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?

  Well, anything. And that is the danger.

  • There may be some code that relies on the UnicodeError being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.
  • The transcoding may produce unexpected or unusable results if not everything on the system uses UTF-8 because Python 2 actually has multiple independent "default string encodings". (Remember, a program must work for the customer, on the customer's equipment.)
    • Again, the worst thing is you will never know that because the conversion is implicit -- you don't really know when and where it happens. (Python Zen, koan 2 ahoy!) You will never know why (and if) your code works on one system and breaks on another. (Or better yet, works in IDE and breaks in console.)

To static either a row or a column, put a $ sign in front of it. So if you were to use the formula =AVERAGE($A1,$C1) and drag it down the entire sheet, A and C would remain static while the 1 would change to the current row

If you're on Windows, you can achieve the same thing by repeatedly pressing F4 while in the formula editing bar. The first F4 press will static both (it will turn A1 into $A$1), then just the row (A$1) then just the column ($A1)

Although technically with the formulas that you have, dragging down for the entirety of the column shouldn't be a problem without putting a $ sign in front of the column. Setting the column as static would only come into play if you're dragging ACROSS columns and want to keep using the same column, and setting the row as static would be for dragging down rows but wanting to use the same row.

A word of caution:

In my experience, omitting the href attribute causes problems for accessibility as the keyboard navigation will ignore it and never give it focus like it will when href is present. Manually including your element in the tabindex is a way around that.

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Give a look also as this SQL Fiddle for test.

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).

Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.

In your onCreate:

 yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
 yourSeekBar.setOnSeekBarChangeListener(new yourListener());

Your listener:

private class yourListener implements SeekBar.OnSeekBarChangeListener {

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
                            // Log the progress
            Log.d("DEBUG", "Progress is: "+progress);
                            //set textView's text
            yourTextView.setText(""+progress);

What you are describing, is an appropriate situation to use Queue.

Since you want to add new element, and remove the old one. You can add at the end, and remove from the beginning. That will not make much of a difference.

Queue has methods add(e) and remove() which adds at the end the new element, and removes from the beginning the old element, respectively.

Queue<Integer> queue = new LinkedList<Integer>();
queue.add(5);
queue.add(6);
queue.remove();  // Remove 5

So, every time you add an element to the queue you can back it up with a remove method call.

UPDATE: -

And if you want to fix the size of the Queue, then you can take a look at: - ApacheCommons#CircularFifoBuffer

From the documentation: -

CircularFifoBuffer is a first in first out buffer with a fixed size that replaces its oldest element if full.

Buffer queue = new CircularFifoBuffer(2); // Max size

queue.add(5);
queue.add(6);
queue.add(7);  // Automatically removes the first element `5`

As you can see, when the maximum size is reached, then adding new element automatically removes the first element inserted.

Please use symbol backtick '`' in your front and end of html string, this is so called template literals, now you able to write pure html in multiple lines and assign to variable.

Have a look at this picture: Graphical Projections

The glOrtho command produces an "Oblique" projection that you see in the bottom row. No matter how far away vertexes are in the z direction, they will not recede into the distance.

I use glOrtho every time I need to do 2D graphics in OpenGL (such as health bars, menus etc) using the following code every time the window is resized:

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0f, windowWidth, windowHeight, 0.0f, 0.0f, 1.0f);

This will remap the OpenGL coordinates into the equivalent pixel values (X going from 0 to windowWidth and Y going from 0 to windowHeight). Note that I've flipped the Y values because OpenGL coordinates start from the bottom left corner of the window. So by flipping, I get a more conventional (0,0) starting at the top left corner of the window rather.

Note that the Z values are clipped from 0 to 1. So be careful when you specify a Z value for your vertex's position, it will be clipped if it falls outside that range. Otherwise if it's inside that range, it will appear to have no effect on the position except for Z tests.

You can use an npm module called depcheck (requires at least version 10 of Node).

1. Install the module:

    npm install depcheck -g
   
    or
   
    yarn global add depcheck
   

2. Run it and find the unused dependencies:

    depcheck
   

The good thing about this approach is that you don't have to remember the find or grep command.

To run without installing use npx:

npx depcheck 

Though my response is late, but it can still help.

lf you are using Spring Tool Suite and you still think that the JQuery file reference path is correct, then refresh your project whenever you modify the JQuery file.

You refresh by right-clicking on the project name -> refresh.

That's what solved mine.

There is already a string handling function Series.str.startswith(). You should try foo[foo.b.str.startswith('f')].

Result:

    a   b
1   2   foo
2   3   fat

I think what you expect.

Alternatively you can use contains with regex option. For example:

foo[foo.b.str.contains('oo', regex= True, na=False)]

Result:

    a   b
1   2   foo

na=False is to prevent Errors in case there is nan, null etc. values

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

Unless you really must implement your own solution, you can use std::minmax_element. This returns a pair of iterators, one to the smallest element and one to the largest.

#include <algorithm>

auto minmax = std::minmax_element(std::begin(values), std::end(values));

std::cout << "min element " << *(minmax.first) << "\n";
std::cout << "max element " << *(minmax.second) << "\n";

class NotImplementedError extends Error {
  constructor(message) {
    super(message);
    this.message = message;
  }
}
NotImplementedError.prototype.name = 'NotImplementedError';
module.exports = NotImplementedError;

and

try {
  var e = new NotImplementedError("NotImplementedError message");
  throw e;
} catch (ex1) {
  console.log(ex1.stack);
  console.log("ex1 instanceof NotImplementedError = " + (ex1 instanceof NotImplementedError));
  console.log("ex1 instanceof Error = " + (ex1 instanceof Error));
  console.log("ex1.name = " + ex1.name);
  console.log("ex1.message = " + ex1.message);
}

It is just a class representation of this answer.

output

NotImplementedError: NotImplementedError message
  ...stacktrace
ex1 instanceof NotImplementedError = true
ex1 instanceof Error = true
ex1.name = NotImplementedError
ex1.message = NotImplementedError message

I copy here the content of a post on my blog

The solution I propose is very simple and easy to implement. Although, it has reached the score of 131040. Several benchmarks of the algorithm performances are presented.

Algorithm

Heuristic scoring algorithm

The assumption on which my algorithm is based is rather simple: if you want to achieve higher score, the board must be kept as tidy as possible. In particular, the optimal setup is given by a linear and monotonic decreasing order of the tile values. This intuition will give you also the upper bound for a tile value: where n is the number of tile on the board.

(There's a possibility to reach the 131072 tile if the 4-tile is randomly generated instead of the 2-tile when needed)

Two possible ways of organizing the board are shown in the following images:

To enforce the ordination of the tiles in a monotonic decreasing order, the score si computed as the sum of the linearized values on the board multiplied by the values of a geometric sequence with common ratio r<1 .

Several linear path could be evaluated at once, the final score will be the maximum score of any path.

Decision rule

The decision rule implemented is not quite smart, the code in Python is presented here:

@staticmethod
def nextMove(board,recursion_depth=3):
    m,s = AI.nextMoveRecur(board,recursion_depth,recursion_depth)
    return m

@staticmethod
def nextMoveRecur(board,depth,maxDepth,base=0.9):
    bestScore = -1.
    bestMove = 0
    for m in range(1,5):
        if(board.validMove(m)):
            newBoard = copy.deepcopy(board)
            newBoard.move(m,add_tile=True)

            score = AI.evaluate(newBoard)
            if depth != 0:
                my_m,my_s = AI.nextMoveRecur(newBoard,depth-1,maxDepth)
                score += my_s*pow(base,maxDepth-depth+1)

            if(score > bestScore):
                bestMove = m
                bestScore = score
    return (bestMove,bestScore);

An implementation of the minmax or the Expectiminimax will surely improve the algorithm. Obviously a more sophisticated decision rule will slow down the algorithm and it will require some time to be implemented.I will try a minimax implementation in the near future. (stay tuned)

Benchmark

• T1 - 121 tests - 8 different paths - r=0.125
• T2 - 122 tests - 8-different paths - r=0.25
• T3 - 132 tests - 8-different paths - r=0.5
• T4 - 211 tests - 2-different paths - r=0.125
• T5 - 274 tests - 2-different paths - r=0.25
• T6 - 211 tests - 2-different paths - r=0.5

In case of T2, four tests in ten generate the 4096 tile with an average score of 42000

Code

The code can be found on GiHub at the following link: https://github.com/Nicola17/term2048-AI It is based on term2048 and it's written in Python. I will implement a more efficient version in C++ as soon as possible.

Here's a simple and intuitive version of checking whether it's a prime in a RECURSIVE function! :) (I did it as a homework assignment for an MIT class) In python it runs very fast until 1900. IF you try more than 1900, you'll get an interesting error :) (Would u like to check how many numbers your computer can manage?)

def is_prime(n, div=2):

    if div> n/2.0: return True

    if n% div == 0:
        return False
    else:
        div+=1
        return is_prime(n,div)

#The program:
until = 1000
for i in range(until):
    if is_prime(i):
        print i

Of course... if you like recursive functions, this small code can be upgraded with a dictionary to seriously increase its performance, and avoid that funny error. Here's a simple Level 1 upgrade with a MEMORY integration:

import datetime
def is_prime(n, div=2):
    global primelist
    if div> n/2.0: return True
    if div < primelist[0]:
        div = primelist[0]
        for x in primelist:
            if x ==0 or x==1: continue
            if n % x == 0:
                return False
    if n% div == 0:
        return False
    else:
        div+=1
        return is_prime(n,div)


now = datetime.datetime.now()
print 'time and date:',now
until = 100000
primelist=[]
for i in range(until):
    if is_prime(i):
        primelist.insert(0,i)
print "There are", len(primelist),"prime numbers, until", until
print primelist[0:100], "..."

finish = datetime.datetime.now()
print "It took your computer", finish - now , " to calculate it"

Here are the resuls, where I printed the last 100 prime numbers found.

time and date: 2013-10-15 13:32:11.674448

There are 9594 prime numbers, until 100000

[99991, 99989, 99971, 99961, 99929, 99923, 99907, 99901, 99881, 99877, 99871, 99859, 99839, 99833, 99829, 99823, 99817, 99809, 99793, 99787, 99767, 99761, 99733, 99721, 99719, 99713, 99709, 99707, 99689, 99679, 99667, 99661, 99643, 99623, 99611, 99607, 99581, 99577, 99571, 99563, 99559, 99551, 99529, 99527, 99523, 99497, 99487, 99469, 99439, 99431, 99409, 99401, 99397, 99391, 99377, 99371, 99367, 99349, 99347, 99317, 99289, 99277, 99259, 99257, 99251, 99241, 99233, 99223, 99191, 99181, 99173, 99149, 99139, 99137, 99133, 99131, 99119, 99109, 99103, 99089, 99083, 99079, 99053, 99041, 99023, 99017, 99013, 98999, 98993, 98981, 98963, 98953, 98947, 98939, 98929, 98927, 98911, 98909, 98899, 98897] ...

It took your computer 0:00:40.871083 to calculate it

So It took 40 seconds for my i7 laptop to calculate it. :)

you can use @see to do that:

sample:

interface View {
        /**
         * @return true: have read contact and call log permissions, else otherwise
         * @see #requestReadContactAndCallLogPermissions()
         */
        boolean haveReadContactAndCallLogPermissions();

        /**
         * if not have permissions, request to user for allow
         * @see #haveReadContactAndCallLogPermissions()
         */
        void requestReadContactAndCallLogPermissions();
    }

-webkit-overflow-scrolling:touch as mentioned in the answer is infact the possible solution.

<div style="overflow:scroll !important; -webkit-overflow-scrolling:touch !important;">
     <iframe src="YOUR_PAGE_URL" width="600" height="400"></iframe>
</div>

But if you are unable to scroll up and down inside the iframe as shown in image below,

you could try scrolling with 2 fingers diagonally like this,

This actually worked in my case, so just sharing it if you haven't still found a solution for this.

row_count = sum(1 for line in open(filename)) worked for me.

Note : sum(1 for line in csv.reader(filename)) seems to calculate the length of first line

FragmentStatePagerAdapter has a private instance variable called mCurrentPrimaryItem of type Fragment. One can only wonder why Android devs did not supplied it with a getter. This variable is instantiated in setPrimaryItem() method. So, override this method in such a way for you to get the reference to this variable. I simply ended up with declaring my own mCurrentPrimaryItem and copying the contents of setPrimaryItem() to my override.

In your implementation of FragmentStatePagerAdapter:

private Fragment mCurrentPrimaryItem = null;

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
    Fragment fragment = (Fragment)object;
    if (fragment != mCurrentPrimaryItem) {
        if (mCurrentPrimaryItem != null) {
            mCurrentPrimaryItem.setMenuVisibility(false);
            mCurrentPrimaryItem.setUserVisibleHint(false);
        }
        if (fragment != null) {
            fragment.setMenuVisibility(true);
            fragment.setUserVisibleHint(true);
        }
        mCurrentPrimaryItem = fragment;
    }
}

public TasksListFragment getCurrentFragment() {
    return (YourFragment) mCurrentPrimaryItem;
}

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

this would work too. just call the function with maxNode in the tree

def k_largest(self, node , k): if k < 0 : return None
if k == 0: return node else: k -=1 return self.k_largest(self.predecessor(node), k)

Use psycopg2-binary instead of psycopg2.

pip install psycopg2-binary

Or you will get the warning below:

UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: http://initd.org/psycopg/docs/install.html#binary-install-from-pypi.

The only way the regex matcher knows you are looking for a digit and not the letter d is to escape the letter (\d). To type the regex escape character in java, you need to escape it (so \ becomes \\). So, there's no way around typing double backslashes for special regex chars.

A simple INSERT INTO SELECT statement:

INSERT INTO persons_table SELECT * FROM customer_table WHERE person_name = 'tom';

DELETE FROM customer_table WHERE person_name = 'tom';

If each file in your program is first compiled to an object file, then the object files are linked together, you need extern. It tells the compiler "This function exists, but the code for it is somewhere else. Don't panic."

Here's a generalization of the answer provided by @Jon Skeet. It is basically the same, only it is usable for any type of array, not only bytes:

public static T[] Combine<T>(T[] first, T[] second)
{
    T[] ret = new T[first.Length + second.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    return ret;
}

public static T[] Combine<T>(T[] first, T[] second, T[] third)
{
    T[] ret = new T[first.Length + second.Length + third.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    Buffer.BlockCopy(third, 0, ret, first.Length + second.Length,
                     third.Length);
    return ret;
}

public static T[] Combine<T>(params T[][] arrays)
{
    T[] ret = new T[arrays.Sum(x => x.Length)];
    int offset = 0;
    foreach (T[] data in arrays)
    {
        Buffer.BlockCopy(data, 0, ret, offset, data.Length);
        offset += data.Length;
    }
    return ret;
}

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

For me below code worked, first sending json string with proper headers

$.ajax({
        type: "POST",
        url : 'save',
        data : JSON.stringify(valObject),
        contentType:"application/json; charset=utf-8",
        dataType:"json",
        success : function(resp){
            console.log(resp);
        },
        error : function(resp){
            console.log(resp);
        }
    });

And then on Spring side -

@RequestMapping(value = "/save", 
                method = RequestMethod.POST,
                consumes="application/json")
public @ResponseBody String  save(@RequestBody ArrayList<KeyValue> keyValList) {
    //Saving call goes here
    return "";
}

Here KeyValue is simple pojo that corresponds to your JSON structure also you can add produces as you wish, I am simply returning string.

My json object is like this -

[{"storedKey":"vc","storedValue":"1","clientId":"1","locationId":"1"},
 {"storedKey":"vr","storedValue":"","clientId":"1","locationId":"1"}]

parameter?: type is a shorthand for parameter: type | undefined

One way of doing it is to use the ClientScriptManager:

Page.ClientScript.RegisterStartupScript(
    GetType(), 
    "MyKey", 
    "Myfunction();", 
    true);

the same problem also happened to me when i training my classification model. the reason caused this problem is as what the warning message said "in labels with no predicated samples", it will caused the zero-division when compute f1-score. I found another solution when i read sklearn.metrics.f1_score doc, there is a note as follows:

When true positive + false positive == 0, precision is undefined; When true positive + false negative == 0, recall is undefined. In such cases, by default the metric will be set to 0, as will f-score, and UndefinedMetricWarning will be raised. This behavior can be modified with zero_division

the zero_division default value is "warn", you could set it to 0 or 1 to avoid UndefinedMetricWarning. it works for me ;) oh wait, there is another problem when i using zero_division, my sklearn report that no such keyword argument by using scikit-learn 0.21.3. Just update your sklearn to the latest version by running pip install scikit-learn -U

2020 Update

It is weird that no one has suggested the OOP way:

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT3600S'));//add 3600s / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT60M'));//add 60 min / 1 hour

OR

$date = new \DateTime(); //now
$date->add(new \DateInterval('PT1H'));//add 1 hour

Extract it in string with format:

var_dump($date->format('Y-m-d H:i:s'));

I hope it helps

From the Android Developer Site link

"adjustResize"

The activity's main window is always resized to make room for the soft keyboard on screen.

"adjustPan"

The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

according to your comment, use following in your activity manifest

<activity android:windowSoftInputMode="adjustResize"> </activity>

Enable assembly binding logging set the registry value EnableLog in HKLM\Software\Microsoft\Fusion to 1. Note that you have to restart your application (use iisreset) for the changes to have any effect.

Tip: Remember to turn off fusion logging when you are done since there is a performance penalty to have it turned on.

just add checked attribute to each radio that you want to have default checked

try this :

<input style="width: 20px;" type="radio" name="Contact0_AmericanExpress" class="check" checked/>

This is one line solution, if you want convert every work in the string, Split the string by " ", iterate over the parts and apply this solution to each part, add every converted part to a array and join it with " ".

var stringToConvert = 'john';_x000D_
stringToConvert = stringToConvert.charAt(0).toUpperCase() + Array.prototype.slice.call(stringToConvert, 1).join('');_x000D_
console.log(stringToConvert);

You can call QCoreApplication::exit(0) to exit with code 0

I found an answer in the above link http://php.net/manual/en/function.mysql-insert-id.php

The answer is:

mysql_query("INSERT INTO tablename (columnname) values ('$value')");        
echo $Id=mysql_insert_id();

I'm pretty sure there'll be some C# SDKs / toolkits on Google Code for this. I found this one, but there may be others so it's worth having a browse around.

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Below code helped my object to be refreshed with fresh database values. The Entry(object).Reload() command forces the object to recall database values

GM_MEMBERS member = DatabaseObjectContext.GM_MEMBERS.FirstOrDefault(p => p.Username == username && p.ApplicationName == this.ApplicationName);
DatabaseObjectContext.Entry(member).Reload();

If you have additional types, edit the selector:

var formElements = new Array();
$("form :input").each(function(){
    formElements.push($(this));
});

All form elements are now in the array formElements.

you can use this for making a list Unique

ArrayList<String> listWithDuplicateValues = new ArrayList<>();
list.add("first");
list.add("first");
list.add("second");

ArrayList uniqueList = (ArrayList) listWithDuplicateValues.stream().distinct().collect(Collectors.toList());

You are missing a space between Basic and the encoded username and password.

headers.set('Authorization', 'Basic ' + base64.encode(username + ":" + password));

In short

creating or moving some/all reference containing worksheets (out and) into your workbook may solve it.

More details

I had this issue after copying some sheets from "template" sheets/workbooks to some new "destination" workbook (the templates were provided by other users!):

I got:

• workbook WbTempl1
  • with sheet WsTempl1RefDef (defining the references used e.g. in WsTempl2RefUsr below, e.g. project on A1)
• workbook WbTempl2 (above references do not exist, because WsTempl1RefDef is not contained nor externally referenced, e.g. like WbTempl2.Names("project").refersTo="C:\WbTempl1.xls]'WsTempl1RefDef!A1")
  • contains sheet WsTempl2RefUsr (uses inexisting global references, e.g. =project)

and wanted to create a WbDst to copy WsTempl1RefDef and WsTempl2RefUsr into it.

The following did not work:

1. create workbook WbDst
2. copy sheet WsTempl1RefDef into it (references were locally created)
3. copy sheet WsTempl2RefUsr into it

Here as well the Ctrl(SHIFT)ALTF9 nor Application.CalculateFullRebuild worked on WbDst.

The following worked:

1. create workbook WbDst
2. move (not copy) sheet WsTempl1RefDef into WbTempl2
   • (we do not have to save them)
3. copy sheet WsTempl1RefDef into WbDst
4. copy sheet WsTempl2RefUsr into WbDst

The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.

Then you can use either _.size(object) or _.keys(object).length

For your obj.Data, you could test this with:

console.log( _.size(obj.Data) );

or:

console.log( _.keys(obj.Data).length );

Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)

Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:

function ObjectLength( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
};

You can test this with:

console.log( ObjectLength(obj.Data) );

That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:

function ObjectLength_Modern( object ) {
    return Object.keys(object).length;
}

function ObjectLength_Legacy( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
}

var ObjectLength =
    Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;

and as before, test it with:

console.log( ObjectLength(obj.Data) );

This code uses Object.keys(object).length in modern browsers and falls back to counting in a loop for old browsers.

But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.

I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.

Thanks to Barmar for suggesting Object.keys for newer browsers in his answer.

If using XML based TextView, for your requirement you need to do just two things:

1. Identify your link in the string, such as "this is my WebPage." You can add it in xml or in the code.

2. In the xml that has the TextView, add these:

android:linksClickable="true"

android:autoLink="web"

For debugging when I start java add like mentioned:

-Djavax.net.debug=ssl

then you can see that the browser tried to use TLSv1 and Jetty 9.1.3 was talking TLSv1.2 so they were not communicating. That's Firefox. Chrome wanted SSLv3 so I added that also.

sslContextFactory.setIncludeProtocols( "TLSv1", "SSLv3" );  <-- Fix
sslContextFactory.setRenegotiationAllowed(true);   <-- added don't know if helps anything.

I did not do most of the other stuff the orig poster did:

// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] {

or this answer:

KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory
        .getDefaultAlgorithm());

or

.setEnabledCipherSuites

I created one self signed cert like this: (but I added .jks to filename) and read that in my jetty java code. http://www.eclipse.org/jetty/documentation/current/configuring-ssl.html

keytool -keystore keystore.jks -alias jetty -genkey -keyalg RSA

The cleanest method would be to add a class with pointer-events:none when you want to disable a click. It would function like a normal label.

.disableClick{
    pointer-events: none;
}

@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.

    var currentZoom = 1.0;

    $(document).ready(function () {
        $('#btn_ZoomIn').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
            })
        $('#btn_ZoomOut').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
            })
        $('#btn_ZoomReset').click(
            function () {
                currentZoom = 1.0
                $('#divName').animate({ 'zoom': 1 }, 'slow');
            })
    });

A nice and easy way for those people who always forget the command axhline is the following

plt.plot(x, [y]*len(x))

In your case xs = x and y = 40. If len(x) is large, then this becomes inefficient and you should really use axhline.

In Swift, the == operator is equivalent to Objective C's isEqual: method (it calls the isEqual method instead of just comparing pointers, and there's a new === method for testing that the pointers are the same), so you can just write this as:

if username == "" || password == ""
{
    println("Sign in failed. Empty character")
}

You declare a function pointer variable for the given signature of your functions like this:

bool (* fnptr)();

you can assign it one of your functions:

fnptr = A;

and you can call it:

bool result = fnptr();

You might consider using typedefs to define a type for every distinct function signature you need. This will make the code easier to read and to maintain. i.e. for the signature of functions returning bool with no arguments this could be:

typdef bool (* BoolFn)();

and then you can use like this to declare the function pointer variable for this type:

BoolFn fnptr;

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

I dont think you need regex to achieve this. I would look at the SubString method along with the indexOf method. If you need more help, add a comment showing what you have attempted and I will offer more help.

A little hacky, but I created an array called "console", and anytime I wanted to output to console I pushed to the array. Then whenever I wanted to see the actual output, I just returned console instead of whatever I was returning before.

    //return 'console' //uncomment to output console
    return "actual output";
}

you can just use

ls > filenames.txt

(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd to go to that folder first, or you can ls ~/docs > filenames.txt

There's one difference — which shouldn't matter — that the other answers haven't touched on, so:

There's no difference that's likely to matter, no. Yes, there is a very small difference.

If the fulfillment handler passed to then throws, the promise returned by that call to then is rejected with what was thrown.

If it returns a rejected promise, the promise returned by the call to then is resolved to that promise (and will ultimately be rejected, since the promise it's resolved to is rejected), which may introduce one extra async "tick" (one more loop in the microtask queue, to put it in browser terms).

Any code that relies on that difference is fundamentally broken, though. :-) It shouldn't be that sensitive to the timing of the promise settlement.

Here's an example:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}
function usingReject(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                return Promise.reject(new Error(`${v} is not 42!`));
            }
            return v;
        });
}

// The rejection handler on this chain may be called **after** the
// rejection handler on the following chain
usingReject(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingReject:", e.message));

// The rejection handler on this chain may be called **before** the
// rejection handler on the preceding chain
usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

If you run that, as of this writing you get:

Error from usingThrow: 2 is not 42!
Error from usingReject: 1 is not 42!

Note the order.

Compare that to the same chains but both using usingThrow:

function usingThrow(val) {
    return Promise.resolve(val)
        .then(v => {
            if (v !== 42) {
                throw new Error(`${v} is not 42!`);
            }
            return v;
        });
}

usingThrow(1)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

usingThrow(2)
.then(v => console.log(v))
.catch(e => console.error("Error from usingThrow:", e.message));

which shows that the rejection handlers ran in the other order:

Error from usingThrow: 1 is not 42!
Error from usingThrow: 2 is not 42!

I said "may" above because there's been some work in other areas that removed this unnecessary extra tick in other similar situations if all of the promises involved are native promises (not just thenables). (Specifically: In an async function, return await x originally introduced an extra async tick vs. return x while being otherwise identical; ES2020 changed it so that if x is a native promise, the extra tick is removed.)

Again, any code that's that sensitive to the timing of the settlement of a promise is already broken. So really it doesn't/shouldn't matter.

In practical terms, as other answers have mentioned:

• As Kevin B pointed out, throw won't work if you're in a callback to some other function you've used within your fulfillment handler — this is the biggie
• As lukyer pointed out, throw abruptly terminates the function, which can be useful (but you're using return in your example, which does the same thing)
• As Vencator pointed out, you can't use throw in a conditional expression (? :), at least not for now

Other than that, it's mostly a matter of style/preference, so as with most of those, agree with your team what you'll do (or that you don't care either way), and be consistent.

I think there is MID() and maybe LEFT() and RIGHT() in Access.

Use css text-transform to display text in all input type text. In Jquery you can then transform the value to uppercase on blur event.

Css:

input[type=text] {
    text-transform: uppercase;
}

Jquery:

$(document).on('blur', "input[type=text]", function () {
    $(this).val(function (_, val) {
        return val.toUpperCase();
    });
});

Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)

"Select destination and Press Enter or Choose Paste"

Then you press whether Enter or choose paste to paste the value of the cell.

If you didn't press Esc afterwards you will be able to paste the value of the cell several times

Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.

And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'

The example you copied from is using data in the form of an array holding arrays, you are using data in the form of an array holding objects. Objects and arrays are not the same, and because of this they use different syntaxes for accessing data.

If you don't know the variable names, just do a var_dump($blog); within the loop to see them.

The simplest method - access $blog as an object directly:

Try (assuming those variables are correct):

<?php 
    foreach ($blogs as $blog) {
        $id         = $blog->id;
        $title      = $blog->title;
        $content    = $blog->content;
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?>

The alternative method - access $blog as an array:

Alternatively, you may be able to turn $blog into an array with get_object_vars (documentation):

<?php
    foreach($blogs as &$blog) {
        $blog     = get_object_vars($blog);
        $id       = $blog['id'];
        $title    = $blog['title'];
        $content  = $blog['content'];
?>

<h1> <?php echo $title; ?></h1>
<h1> <?php echo $content; ?> </h1>

<?php } ?> 

It's worth mentioning that this isn't necessarily going to work with nested objects so its viability entirely depends on the structure of your $blog object.

Better than either of the above - Inline PHP Syntax

Having said all that, if you want to use PHP in the most readable way, neither of the above are right. When using PHP intermixed with HTML, it's considered best practice by many to use PHP's alternative syntax, this would reduce your whole code from nine to four lines:

<?php foreach($blogs as $blog): ?>
    <h1><?php echo $blog->title; ?></h1>
    <p><?php echo $blog->content; ?></p>
<?php endforeach; ?>

Hope this helped.

describe tablename

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

getch() can also be used which is defined in conio.h.

The sample program would look like this :

#include <stdio.h>
#include <conio.h>

int main()
{
    //your code 
    getch();
    return 0; 
} 

getch() waits for any character input from the keyboard (not necessarily enter key).

Assuming that we know Struct is a value type and Class is a reference type.

_{If you don't know what a value type and a reference type are then see What's the difference between passing by reference vs. passing by value?}

Based on mikeash's post:

... Let's look at some extreme, obvious examples first. Integers are obviously copyable. They should be value types. Network sockets can't be sensibly copied. They should be reference types. Points, as in x, y pairs, are copyable. They should be value types. A controller that represents a disk can't be sensibly copied. That should be a reference type.

Some types can be copied but it may not be something you want to happen all the time. This suggests that they should be reference types. For example, a button on the screen can conceptually be copied. The copy will not be quite identical to the original. A click on the copy will not activate the original. The copy will not occupy the same location on the screen. If you pass the button around or put it into a new variable you'll probably want to refer to the original button, and you'd only want to make a copy when it's explicitly requested. That means that your button type should be a reference type.

View and window controllers are a similar example. They might be copyable, conceivably, but it's almost never what you'd want to do. They should be reference types.

What about model types? You might have a User type representing a user on your system, or a Crime type representing an action taken by a User. These are pretty copyable, so they should probably be value types. However, you probably want updates to a User's Crime made in one place in your program to be visible to other parts of the program. This suggests that your Users should be managed by some sort of user controller which would be a reference type. e.g

struct User {}
class UserController {
    var users: [User]

    func add(user: User) { ... }
    func remove(userNamed: String) { ... }
    func ...
}

Collections are an interesting case. These include things like arrays and dictionaries, as well as strings. Are they copyable? Obviously. Is copying something you want to happen easily and often? That's less clear.

Most languages say "no" to this and make their collections reference types. This is true in Objective-C and Java and Python and JavaScript and almost every other language I can think of. (One major exception is C++ with STL collection types, but C++ is the raving lunatic of the language world which does everything strangely.)

Swift said "yes," which means that types like Array and Dictionary and String are structs rather than classes. They get copied on assignment, and on passing them as parameters. This is an entirely sensible choice as long as the copy is cheap, which Swift tries very hard to accomplish. ...

_{I personally don't name my classes like that. I usually name mine UserManager instead of UserController but the idea is the same}

In addition don't use class when you have to override each and every instance of a function ie them not having any shared functionality.

So instead of having several subclasses of a class. Use several structs that conform to a protocol.

Another reasonable case for structs is when you want to do a delta/diff of your old and new model. With references types you can't do that out of the box. With value types the mutations are not shared.

This may work as well.

SELECT * 
FROM myTable
WHERE CHARINDEX('mall', name) > 0
  OR CHARINDEX('mall', description) > 0

You can use import data with wizard and there you can choose destination table.

Run the wizard. In selecting source tables and views window you see two parts. Source and Destination.

Click on the field under Destination part to open the drop down and select you destination table and edit its mappings if needed.

EDIT

Merely typing the name of the table does not work. It appears that the name of the table must include the schema (dbo) and possibly brackets. Note the dropdown on the right hand side of the text field.

A mutable dictionary can be changed, i.e. you can add and remove objects. An immutable is fixed once it is created.

create and add:

NSMutableDictionary *dict = [[NSMutableDictionary alloc]initWithCapacity:10];
[dict setObject:[NSNumber numberWithInt:42] forKey:@"A cool number"];

and retrieve:

int myNumber = [[dict objectForKey:@"A cool number"] intValue];

this worked for me inside a directive and works without refreshing the baseurl (just adds the endpoint).Good for Single Page Apps with routing mechanism.

  $(location).attr('href', 'http://localhost:10005/#/endpoint') 

This also happens if you forget selfdeclaration inside class methods.

Example:

class Example():
    def is_overlapping(x1, x2, y1, y2):
        # Thanks to https://stackoverflow.com/a/12888920/940592
        return max(x1, y1) <= min(x2, y2)

Fails calling it like self.is_overlapping(x1=2, x2=4, y1=3, y2=5) with:

{TypeError} is_overlapping() got multiple values for argument 'x1'

WORKS:

class Example():
    def is_overlapping(self, x1, x2, y1, y2):
        # Thanks to https://stackoverflow.com/a/12888920/940592
        return max(x1, y1) <= min(x2, y2)

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

Scanner scan = new Scanner (System.in);

for (int i=0; i<=4, i++){

    System.out.printf("Enter value at index"+i+" :");

    anArray[i]=scan.nextInt();

}

class A{
public:
   static const char* SOMETHING() { return "something"; }
};

I do it all the time - especially for expensive const default parameters.

class A{
   static
   const expensive_to_construct&
   default_expensive_to_construct(){
      static const expensive_to_construct xp2c(whatever is needed);
      return xp2c;
   }
};

array_merge() is more efficient but there are a couple of options:

$array1 = array("id1" => "value1");

$array2 = array("id2" => "value2", "id3" => "value3", "id4" => "value4");

$array3 = array_merge($array1, $array2/*, $arrayN, $arrayN*/);
$array4 = $array1 + $array2;

echo '<pre>';
var_dump($array3);
var_dump($array4);
echo '</pre>';


// Results:
    array(4) {
      ["id1"]=>
      string(6) "value1"
      ["id2"]=>
      string(6) "value2"
      ["id3"]=>
      string(6) "value3"
      ["id4"]=>
      string(6) "value4"
    }
    array(4) {
      ["id1"]=>
      string(6) "value1"
      ["id2"]=>
      string(6) "value2"
      ["id3"]=>
      string(6) "value3"
      ["id4"]=>
      string(6) "value4"
    }

ImageArtist is a pure gd wrapper authored by me, this enables you to do complex image manipulations insanely easy, for your question solution can be done using very few steps using this powerful library.

here is a sample code.

$img1 = new Image("./cover.jpg");
$img2 = new Image("./box.png");
$img2->merge($img1,9,9);
$img2->save("./merged.png",IMAGETYPE_PNG);

This is how my result looks like.

From the command line, .exit is what you want:

$ node
> .exit
$

It's documented in the REPL docs. REPL (Read-Eval-Print-Loop) is what the Node command line is called.

From a normal program, use process.exit([code]).

Just in case if any one is stuck like me. After going though the post and some hit and trial this worked for me.

input:not([type="checkbox"])input:not([type="radio"])

Intercept the KeyPressed event is in my opinion a good solid solution. Pay attention to trigger code characters (e.KeyChar lower then 32) if you use a RegExp.

But in this way is still possible to inject characters out of range whenever the user paste text from the clipboard. Unfortunately I did not found correct clipboard events to fix this.

So a waterproof solution is to intercept TextBox.TextChanged. Here is sometimes the original out of range character visible, for a short time. I recommend to implement both.

using System.Text.RegularExpressions;

private void Form1_Shown(object sender, EventArgs e)
{
    filterTextBoxContent(textBox1);
}


string pattern = @"[^0-9^+^\-^/^*^(^)]";

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    if(e.KeyChar >= 32 && Regex.Match(e.KeyChar.ToString(), pattern).Success) { e.Handled = true; }
}

private void textBox1_TextChanged(object sender, EventArgs e)
{
    filterTextBoxContent(textBox1);
}

private bool filterTextBoxContent(TextBox textBox)
{
    string text = textBox.Text;

    MatchCollection matches = Regex.Matches(text, pattern);
    bool matched = false;

    int selectionStart = textBox.SelectionStart;
    int selectionLength = textBox.SelectionLength;

    int leftShift = 0;
    foreach (Match match in matches)
    {
        if (match.Success && match.Captures.Count > 0)
        {
            matched = true;
            Capture capture = match.Captures[0];

            int captureLength = capture.Length;
            int captureStart = capture.Index - leftShift;
            int captureEnd = captureStart + captureLength;

            int selectionEnd = selectionStart + selectionLength;

            text = text.Substring(0, captureStart) + text.Substring(captureEnd, text.Length - captureEnd);

            textBox.Text = text;

            int boundSelectionStart = selectionStart < captureStart ? -1 : (selectionStart < captureEnd ? 0 : 1);
            int boundSelectionEnd = selectionEnd < captureStart ? -1 : (selectionEnd < captureEnd ? 0 : 1);

            if (boundSelectionStart == -1)
            {
                if (boundSelectionEnd == 0)
                {
                    selectionLength -= selectionEnd - captureStart;
                }
                else if (boundSelectionEnd == 1)
                {
                    selectionLength -= captureLength;
                }
            }
            else if (boundSelectionStart == 0)
            {
                if (boundSelectionEnd == 0)
                {
                    selectionStart = captureStart;
                    selectionLength = 0;
                }
                else if (boundSelectionEnd == 1)
                {
                    selectionStart = captureStart;
                    selectionLength -= captureEnd - selectionStart;
                }
            }
            else if (boundSelectionStart == 1)
            {
                selectionStart -= captureLength;
            }

            leftShift++;
        }
    }

    textBox.SelectionStart = selectionStart;
    textBox.SelectionLength = selectionLength;

    return matched;
}

Your construction is illegal. You cannot include parameters in the action value of a form. What happens if you try this is going to depend on quirks of the browser. I wouldn't be surprised if it worked with one browser and not another. Even if it appeared to work, I would not rely on it, because the next version of the browser might change the behavior.

"But lets say I have parameters in query string and in hidden inputs, what can I do?" What you can do is fix the error. Not to be snide, but this is a little like asking, "But lets say my URL uses percent signs instead of slashes, what can I do?" The only possible answer is, you can fix the URL.

The generally-preferred code for 10.5+/iOS.

for (id object in array) {
    // do something with object
}

This construct is used to enumerate objects in a collection which conforms to the NSFastEnumeration protocol. This approach has a speed advantage because it stores pointers to several objects (obtained via a single method call) in a buffer and iterates through them by advancing through the buffer using pointer arithmetic. This is much faster than calling -objectAtIndex: each time through the loop.

It's also worth noting that while you technically can use a for-in loop to step through an NSEnumerator, I have found that this nullifies virtually all of the speed advantage of fast enumeration. The reason is that the default NSEnumerator implementation of -countByEnumeratingWithState:objects:count: places only one object in the buffer on each call.

I reported this in radar://6296108 (Fast enumeration of NSEnumerators is sluggish) but it was returned as Not To Be Fixed. The reason is that fast enumeration pre-fetches a group of objects, and if you want to enumerate only to a given point in the enumerator (e.g. until a particular object is found, or condition is met) and use the same enumerator after breaking out of the loop, it would often be the case that several objects would be skipped.

If you are coding for OS X 10.6 / iOS 4.0 and above, you also have the option of using block-based APIs to enumerate arrays and other collections:

[array enumerateObjectsUsingBlock:^(id object, NSUInteger idx, BOOL *stop) {
    // do something with object
}];

You can also use -enumerateObjectsWithOptions:usingBlock: and pass NSEnumerationConcurrent and/or NSEnumerationReverse as the options argument.

10.4 or earlier

The standard idiom for pre-10.5 is to use an NSEnumerator and a while loop, like so:

NSEnumerator *e = [array objectEnumerator];
id object;
while (object = [e nextObject]) {
  // do something with object
}

I recommend keeping it simple. Tying yourself to an array type is inflexible, and the purported speed increase of using -objectAtIndex: is insignificant to the improvement with fast enumeration on 10.5+ anyway. (Fast enumeration actually uses pointer arithmetic on the underlying data structure, and removes most of the method call overhead.) Premature optimization is never a good idea — it results in messier code to solve a problem that isn't your bottleneck anyway.

When using -objectEnumerator, you very easily change to another enumerable collection (like an NSSet, keys in an NSDictionary, etc.), or even switch to -reverseObjectEnumerator to enumerate an array backwards, all with no other code changes. If the iteration code is in a method, you could even pass in any NSEnumerator and the code doesn't even have to care about what it's iterating. Further, an NSEnumerator (at least those provided by Apple code) retains the collection it's enumerating as long as there are more objects, so you don't have to worry about how long an autoreleased object will exist.

Perhaps the biggest thing an NSEnumerator (or fast enumeration) protects you from is having a mutable collection (array or otherwise) change underneath you without your knowledge while you're enumerating it. If you access the objects by index, you can run into strange exceptions or off-by-one errors (often long after the problem has occurred) that can be horrific to debug. Enumeration using one of the standard idioms has a "fail-fast" behavior, so the problem (caused by incorrect code) will manifest itself immediately when you try to access the next object after the mutation has occurred. As programs get more complex and multi-threaded, or even depend on something that third-party code may modify, fragile enumeration code becomes increasingly problematic. Encapsulation and abstraction FTW! :-)

I had this problem using GitExtensions on windows. Fixed by granting full permission for the current user (me) on the folder that contained the repo.

Another time, I even though I was getting the error from Git Extensions, I was able to commit the same files from Visual Studio 2015.

Another time I had to delete the "index" file from the .git folder

The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process's virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That's why you are getting the access violation error.

When the user session times out, I send back an HTTP 204 status code. Note that the HTTP 204 status contains no content. On the client-side I do this:

xhr.send(null);
if (xhr.status == 204) 
    Reload();
else 
    dropdown.innerHTML = xhr.responseText;

Here is the Reload() function:

function Reload() {
    var oForm = document.createElement("form");
    document.body.appendChild(oForm);
    oForm.submit();
    }

In kotlin: Object class implements Serializable:

class MyClass: Serializable {
//members
}

At the point where the object sending:

val fragment = UserDetailFragment()
val bundle = Bundle()
bundle.putSerializable("key", myObject)
fragment.arguments = bundle

At the fragment, where we want to get our object:

val bundle: Bundle? = arguments
    bundle?.let {
        val myObject = it.getSerializable("key") as MyClass
        myObject.memberName?.let { it1 -> showShortToast(it1) }
    }

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)

When I need to get the directory, not only for the plugins (plugin_dir_path), but a more generic one, you can use __DIR__, it will give you the path of the directory of the file where is called. Now you can used from functions.php or another file!

Description:

The directory of the file. If used inside an include, the directory of the included file is returned. This is equivalent to dirname(__FILE__). This directory name does not have a trailing slash unless it is the root directory. 1

if you are using jquery 1.7

$('html').off('click');

else

$('html').unbind('click');

The question has not been completely answered, IMHO. I will try to explain: I have a crontab entry that schedules a bash shell command procedure, that in turn does some cleanup of my files; and, when done, sends a notification to me using the OS X notification center (with the command osascript -e 'display notification ...). If someone (e.g. my wife or my daughter) switches the current user of the computer to her, leaving me in the background, the cron script fails when sending the notification.

So, Who is the current user means Has some other people become the effective user leaving me in the background? Do stat -f "%Su" /dev/console returns the current active user name?

The answer is yes; so, now my crontab shell script has been modified in the following way:

...
if [ "$(/usr/bin/stat -f ""%Su"" /dev/console)" = "loreti" ]
then /usr/bin/osascript -e \
  'display notification "Cleanup done" sound name "sosumi" with title "myCleanup"'
fi

With the render method potentially deprecating the returned value, the recommended approach is now to attach a callback ref to the root element. Like this:

ReactDOM.render( <Hello name="World" ref={(element) => {window.helloComponent = element}}/>, document.getElementById('container'));

which we can then access using window.helloComponent, and any of its methods can be accessed with window.helloComponent.METHOD.

Here's a full example:

var onButtonClick = function() {_x000D_
  window.helloComponent.alertMessage();_x000D_
}_x000D_
_x000D_
class Hello extends React.Component {_x000D_
  alertMessage() {_x000D_
    alert(this.props.name);_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return React.createElement("div", null, "Hello ", this.props.name);_x000D_
  }_x000D_
};_x000D_
_x000D_
ReactDOM.render( <Hello name="World" ref={(element) => {window.helloComponent = element}}/>, document.getElementById('container'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="container"></div>_x000D_
<button onclick="onButtonClick()">Click me!</button>

You can use this js code. Just change .post-thumb img with your img.

$('.post-thumb img').each(function(){           // Note: {.post-thumb img} is css selector of the image tag
    var t = $(this),
        s = 'url(' + t.attr('src') + ')',
        p = t.parent(),
        d = $('<div></div>');
    t.hide();
    p.append(d);
    d.css({
        'height'                : 260,          // Note: You can change it for your needs
        'background-size'       : 'cover',
        'background-repeat'     : 'no-repeat',
        'background-position'   : 'center',
        'background-image'      : s
    });
});

Probably, contents of the JAR files in your local .m2 repository are HTML saying "301 Moved Permanently". It seems that mvn does not handle "301 Moved Permanently" properly as expected. In such a case, download the JAR files manually from somewhere (the central repository, for example) and put them into your .m2 repository.

I just release my latest library for Google Maps Direction API on Android https://github.com/akexorcist/Android-GoogleDirectionLibrary

If you need to store a member function without the class instance, you can do something like this:

class MyClass
{
public:
    void MemberFunc(int value)
    {
      //do something
    }
};

// Store member function binding
auto callable = std::mem_fn(&MyClass::MemberFunc);

// Call with late supplied 'this'
MyClass myInst;
callable(&myInst, 123);

What would the storage type look like without auto? Something like this:

std::_Mem_fn_wrap<void,void (__cdecl TestA::*)(int),TestA,int> callable

You can also pass this function storage to a standard function binding

std::function<void(int)> binding = std::bind(callable, &testA, std::placeholders::_1);
binding(123); // Call

Past and future notes: An older interface std::mem_func existed, but has since been deprecated. A proposal exists, post C++17, to make pointer to member functions callable. This would be most welcome.

Because Google led me here, on Ubuntu 20.04 this works in 2020:

sudo apt install php7.4-xml

If on Apache2, remember to restart (probably not necessary):

sudo systemctl restart apache2

Code:

function search($array, $key, $value)
{
    $results = array();

    if (is_array($array)) {
        if (isset($array[$key]) && $array[$key] == $value) {
            $results[] = $array;
        }

        foreach ($array as $subarray) {
            $results = array_merge($results, search($subarray, $key, $value));
        }
    }

    return $results;
}

$arr = array(0 => array(id=>1,name=>"cat 1"),
             1 => array(id=>2,name=>"cat 2"),
             2 => array(id=>3,name=>"cat 1"));

print_r(search($arr, 'name', 'cat 1'));

Output:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => cat 1
        )

    [1] => Array
        (
            [id] => 3
            [name] => cat 1
        )

)

If efficiency is important you could write it so all the recursive calls store their results in the same temporary $results array rather than merging arrays together, like so:

function search($array, $key, $value)
{
    $results = array();
    search_r($array, $key, $value, $results);
    return $results;
}

function search_r($array, $key, $value, &$results)
{
    if (!is_array($array)) {
        return;
    }

    if (isset($array[$key]) && $array[$key] == $value) {
        $results[] = $array;
    }

    foreach ($array as $subarray) {
        search_r($subarray, $key, $value, $results);
    }
}

The key there is that search_r takes its fourth parameter by reference rather than by value; the ampersand & is crucial.

FYI: If you have an older version of PHP then you have to specify the pass-by-reference part in the call to search_r rather than in its declaration. That is, the last line becomes search_r($subarray, $key, $value, &$results).

mysql> GRANT ALL ON *.* to root@'192.168.1.%' IDENTIFIED BY 'your-root-password';  

The wildcard character is a "%" instead of an "*"

JavaScript uses the \ (backslash) as an escape characters for:

• \' single quote
• \" double quote
• \ backslash
• \n new line
• \r carriage return
• \t tab
• \b backspace
• \f form feed
• \v vertical tab (IE < 9 treats '\v' as 'v' instead of a vertical tab ('\x0B'). If cross-browser compatibility is a concern, use \x0B instead of \v.)
• \0 null character (U+0000 NULL) (only if the next character is not a decimal digit; else it’s an octal escape sequence)

Note that the \v and \0 escapes are not allowed in JSON strings.

I have had the same problem (on several different servers). Applying SP3 and Report Viewer SP1 has helped on some of the servers, allowing the client machines to connect and download the control with no problem. However, I have had one server that, even after applying the updates, when accessing the report viewer using a client machine, it was still giving me the error. On looking into the exact URL GET request that is being sent, I discovered that it is possible to force the client machine to connect directly to the Report Server to download the control.

The user would need to enter the following url:

http://reportservername/Reports/Reserved.ReportViewerWebControl.axd?ReportSession=51bjqv45xydgos2wghu5ceza&ControlID=7617dedbf0234f89b80cad8e64431014&Culture=2057&UICulture=9&ReportStack=1&OpType=PrintHtml

This should then pop up the required download/install prompt.

Although not usually a concern, from a security perspective, it is better to use synchronized on a private object, rather than putting it on a method.

Putting it on the method means you are using the lock of the object itself to provide thread safety. With this kind of mechanism, it is possible for a malicious user of your code to also obtain the lock on your object, and hold it forever, effectively blocking other threads. A non-malicious user can effectively do the same thing inadvertently.

If you use the lock of a private data member, you can prevent this, since it is impossible for a malicious user to obtain the lock on your private object.

private final Object lockObject = new Object();

public void getCount() {
    synchronized( lockObject ) {
        ...
    }
}

This technique is mentioned in Bloch's Effective Java (2nd Ed), Item #70

If you are using Angular UI Bootstrap, you can use tooltip with html syntax: tooltip-html-unsafe

M-^ is copy Text. "M" in my environment is "Esc" key ! not "Ctrl"; so I use Esc + 6 to copy that.

[nano help] Escape-key sequences are notated with the Meta (M-) symbol and can be entered using either the Esc, Alt, or Meta key depending on your keyboard setup.

By Using data.table we can specify data types for each column.

library(data.table)    
data=data.table(a=numeric(), b=numeric(), c=numeric())

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

On Windows I had solved this problem in the following way :

1) uninstalled Python

2) navigated to C:\Users\MyName\AppData\Local\Programs(your should turn on hidden files visibility Show hidden files instruction)

3) deleted 'Python' folder

4) installed Python

I didnt try Sumama Waheed's answer but what worked for me was replacing the bin/catalina.jar with a working jar (I disposed of an older tomcat) and after adding in NetBeans, I put the original catalina.jar again.

Basically, there are two ways to set / update data attribute value, depends on your need. The difference is just, where the data saved,

If you use .data() it will be saved in local variable called data_user, and its not visible upon element inspection, If you use .attr() it will be publicly visible.

You can't initialize your testArray field this way, because the application resources still aren't ready.

Just change the code to:

package com.xtensivearts.episode.seven;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class Episode7 extends ListActivity {
    String[] mTestArray;

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create an ArrayAdapter that will contain all list items
        ArrayAdapter<String> adapter;

        mTestArray = getResources().getStringArray(R.array.testArray);    

        /* Assign the name array to that adapter and 
        also choose a simple layout for the list items */ 
        adapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_list_item_1,
            mTestArray);

        // Assign the adapter to this ListActivity
        setListAdapter(adapter);
    }
}

AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.

As the OP specifically asked for a jQuery implementation, here you go:

<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
    <input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
    <button>Upload!</button>
</form>

$('#upload').submit(function(e) {
    e.preventDefault(); // stop the standard form submission

    $.ajax({
        url: this.action,
        type: this.method,
        data: new FormData(this),
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
        },
        error: function(xhr, error, status) {
            console.log(error, status);
        }
    });
});

public JsonResult Survey()
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        var file = Request.Files[i];
        // save file as required here...
    }
    return Json(new { UploadedFileCount = Request.Files.Count });
}

More information on FormData at MDN

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

EPL2011_12$Date <- as.Date(EPL2011_12$Date, "%d-%m-%y")

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();

Get a count of only the directories in the current directory

echo */ | wc

you will get out put like 1 309 4594

2nd digit represents no. of directories.

or

tree -L 1 | tail -1

You don't need to call $.toJSON and add traditional = true

data: { sendInfo: array },
traditional: true

would do.

According to the certification exam you should use Convert.ToXXX() whenever possible for simple conversions because it optimizes performance better than CXXX conversions.

Is the name of your service class really IService (on the Service namespace)? What you probably had originally was a mismatch in the name of the service class in the name attribute of the <service> element.

This answer is a little long-winded, and the documentation will not tell you this (because they assume you are storing your dates as UTC dates in the database), but the answer to this question depends largely on the timezone that your dates are stored in. You also don't use Date('now'), but use the julianday() function, to calculate both dates back against a common date, then subtract the difference of those results from each other.

If your dates are stored in UTC:

SELECT julianday('now') - julianday(DateCreated) FROM Payment;

This is what the top-ranked answer has, and is also in the documentation. It is only part of the picture, and a very simplistic answer, if you ask me.

If your dates are stored in local time, using the above code will make your answer WRONG by the number of hours your GMT offset is. If you are in the Eastern U.S. like me, which is GMT -5, your result will have 5 hours added onto it. And if you try making DateCreated conform to UTC because julianday('now') goes against a GMT date:

SELECT julianday('now') - julianday(DateCreated, 'utc') FROM Payment;

This has a bug where it will add an hour for a DateCreated that is during Daylight Savings Time (March-November). Say that "now" is at noon on a non-DST day, and you created something back in June (during DST) at noon, your result will give 1 hour apart, instead of 0 hours, for the hours portion. You'd have to write a function in your application's code that is displaying the result to modify the result and subtract an hour from DST dates. I did that, until I realized there's a better solution to that problem that I was having: SQLite vs. Oracle - Calculating date differences - hours

Instead, as was pointed out to me, for dates stored in local time, make both match to local time:

SELECT julianday('now', 'localtime') - julianday(DateCreated) FROM Payment;

Or append 'Z' to local time:

julianday(datetime('now', 'localtime')||'Z') - julianday(CREATED_DATE||'Z')

Both of these seem to compensate and do not add the extra hour for DST dates and do straight subtraction - so that item created at noon on a DST day, when checking at noon on a non-DST day, will not get an extra hour when performing the calculation.

And while I recognize most will say don't store dates in local time in your database, and to store them in UTC so you don't run into this, well not every application has a world-wide audience, and not every programmer wants to go through the conversion of EVERY date in their system to UTC and back again every time they do a GET or SET in the database and deal with figuring out if something is local or in UTC.

If you are using spring with application.yml the following will work for you

spring: datasource: url: jdbc:h2:mem:mydb;DB_CLOSE_ON_EXIT=FALSE;MODE=PostgreSQL;INIT=CREATE SCHEMA IF NOT EXISTS calendar

As Josh has stated above, you want to give each one the same name (letter, button, etc.) and all of them work. Then you want to surround all of these with a form tag:

<form name="myLetters" action="yourScript.php" method="POST">
<!-- Enter your values here with the following syntax: -->
<input type="radio" name="letter" value="A" /> A
<!-- Then add a submit value & close your form -->
<input type="submit" name="submit" value="Choose Letter!" />
</form>

Then, in the PHP script "yourScript.php" as defined by the action attribute, you can use:

$_POST['letter']

To get the value chosen.

You have several errors there.

First, you have to return a value from the function in the HTML markup: <form name="ff1" method="post" onsubmit="return validateForm();">

Second, in the JSFiddle, you place the code inside onLoad which and then the form won't recognize it - and last you have to return true from the function if all validation is a success - I fixed some issues in the update:

https://jsfiddle.net/mj68cq0b/

function validateURL(url) {
    var reurl = /^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/;
    return reurl.test(url);
}

function validateForm()
{
    // Validate URL
    var url = $("#frurl").val();
    if (validateURL(url)) { } else {
        alert("Please enter a valid URL, remember including http://");
        return false;
    }

    // Validate Title
    var title = $("#frtitle").val();
    if (title=="" || title==null) {
        alert("Please enter only alphanumeric values for your advertisement title");
        return false;
    }

    // Validate Email
    var email = $("#fremail").val();
    if ((/(.+)@(.+){2,}\.(.+){2,}/.test(email)) || email=="" || email==null) { } else {
        alert("Please enter a valid email");
        return false;
    }
  return true;
}

int myNegInt = System.Math.Abs(myNumber) * (-1);

b has a capacity of 3, but a size of 0. The fact that ArrayList has some sort of buffer capacity is an implementation detail - it's not part of the List interface, so Collections.copy(List, List) doesn't use it. It would be ugly for it to special-case ArrayList.

As MrWiggles has indicated, using the ArrayList constructor which takes a collection is the way to in the example provided.

For more complicated scenarios (which may well include your real code), you may find the collections within Guava useful.

I had a similar problem due to a zombie vim.exe process. Killing it in Task Manager, followed by a git rebase --abort fixed it.

i had the same problem long time ago, and it fixed it using

locate catalina.out and find out where is your catalina out. Because it depends.

If there is several, look at their sizes: that with size 0 are not what you want.

Look into the File class.

You can create a streamwriter with

StreamWriter sw = File.Create(....) 

You can open an existing file with

File.Open(...)
