Just add position:absolute; top:0; right:0; to the CSS for your button.

 #button {
     line-height: 12px;
     width: 18px;
     font-size: 8pt;
     font-family: tahoma;
     margin-top: 1px;
     margin-right: 2px;
     position:absolute;
     top:0;
     right:0;
 }

jsFiddle example

In case you just need one (first) value to retrieve from xml:

public static String getTagValue(String xml, String tagName){
    return xml.split("<"+tagName+">")[1].split("</"+tagName+">")[0];
}

In case you want to parse whole xml document use JSoup:

Document doc = Jsoup.parse(xml, "", Parser.xmlParser());
for (Element e : doc.select("Request")) {
    System.out.println(e);
}

According to me @Html.RenderPartial() has faster execution than @Html.Partial() due to Html.RenderPartial gives a quick response to Output.

Because when I use @Html.Partial(), my website takes more time to load compared to @Html.RenderPartial()

I modified a few lines in Sander Marechal's code sample (mentioned by @JeffBauer in the accepted answer) to add a quit() method that gets executed before the daemon is stopped. This is sometimes very useful.

Here it is.

Note: I don't use the "python-daemon" module because the documentation is still missing (see also many other SO questions) and is rather obscure (how to start/stop properly a daemon from command line with this module?)

If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:

First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.

package financialdocuments;

import java.lang.*;
import java.util.HashMap;

/**
 *
 * @author Administrator
 */
public class Document {

 private int document_number; 
 private boolean document_type;
 private boolean document_status; 
 private StringBuilder document_date;
 private StringBuilder document_statement;
 private int document_code_number;
 private int document_employee_number;
 private int document_client_number;
 private String document_employee_name;
 private String document_client_name;
 private long document_amount;
 private long document_payment_amount;

 HashMap<Integer,Activity> document_activity_hashmap;


public Document(int dn,boolean dt,boolean ds,String dd,String dst,int dcon,int den,int dcln,long da,String dena,String dcna){

    document_date = new StringBuilder(dd);
    document_date.setLength(10);
    document_date.setCharAt(4, '.');
    document_date.setCharAt(7, '.');
    document_statement = new StringBuilder(dst);
    document_statement.setLength(50);
    document_number = dn; 
    document_type = dt;
    document_status = ds;
    document_code_number = dcon;
    document_employee_number = den;
    document_client_number = dcln;
    document_amount = da;
    document_employee_name = dena;
    document_client_name = dcna;

    document_payment_amount = 0;

    document_activity_hashmap = new HashMap<>();

}

public Document(int dn,boolean dt,boolean ds, long dpa){

    document_number = dn; 
    document_type = dt;
    document_status = ds;

    document_payment_amount = dpa;

    document_activity_hashmap = new HashMap<>();

}

// Print document information 
public void printDocumentInformation (){
    System.out.println("Document Number:" + document_number); 
    System.out.println("Document Date:" + document_date); 
    System.out.println("Document Type:" + document_type); 
    System.out.println("Document Status:" + document_status); 
    System.out.println("Document Statement:" + document_statement); 
    System.out.println("Document Code Number:" + document_code_number); 
    System.out.println("Document Client Number:" + document_client_number); 
    System.out.println("Document Employee Number:" + document_employee_number); 
    System.out.println("Document Amount:" + document_amount); 
    System.out.println("Document Payment Amount:" + document_payment_amount); 
    System.out.println("Document Employee Name:" + document_employee_name); 
    System.out.println("Document Client Name:" + document_client_name); 

} 
} 

Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

package financialdocuments;

I hope this could be a little help.

hey I understand this is an old thread but I have a query in regards to apachebenchmarking. how do you collect the metrics from apache benchmarking. P.S: I have to do it via telegraf and put it to influxdb . any suggestions/advice/help would be appreciated. Thanks a ton.

Be careful of race conditions: if the file disappears between the "exists" check and the time you open it, your program will fail unexpectedly.

It's better to go and open the file, check for failure and if all is good then do something with the file. It's even more important with security-critical code.

Details about security and race conditions: http://www.ibm.com/developerworks/library/l-sprace.html

Swift 4.x

To Change the selection background Colour to anyColour use Swift Extension

Create UITableView Cell extension as below

extension UITableViewCell{

    func removeCellSelectionColour(){
        let clearView = UIView()
        clearView.backgroundColor = UIColor.clear
        UITableViewCell.appearance().selectedBackgroundView = clearView
    } 

}

Then call removeCellSelectionColour() with cell instance.

add CSS or class to the input element which works in select and text tags like

style="pointer-events: none;background-color:#E9ECEF"

DataView view = new DataView();
view.Table = DataSet1.Tables["Suppliers"];
view.RowFilter = "City = 'Berlin'";
view.RowStateFilter = DataViewRowState.ModifiedCurrent;
view.Sort = "CompanyName DESC";

// Simple-bind to a TextBox control
Text1.DataBindings.Add("Text", view, "CompanyName");

Ref: http://www.csharp-examples.net/dataview-rowfilter/

http://msdn.microsoft.com/en-us/library/system.data.dataview.rowfilter.aspx

Try doing the following

if (String.IsNullOrEmpty(MaterialTextBox.Text) || String.IsNullOrWhiteSpace(MaterialTextBox.Text))
    {
        //do job
    }
    else
    {
        MessageBox.Show("Please enter correct path");
    }

Hope it helps

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

Here are two ways.

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

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

<?php

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

?>

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

would need to be changed to:

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

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

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

Very late, but here is the answer you want:

https://api.github.com/repos/ [git username] / [git project] /releases

Next, find the id of the project you are looking for in the data. It should be near the top, next to the urls. Then, navigate to

https://api.github.com/repos/ [git username] / [git project] /releases/ [id] / assets

The field named download_count is your answer.

EDIT: Capitals matter in your username and project name

Simple condition:

if any(str(elem) in ['a','b'] for elem in df['column'].tolist()):

Do you mean counting the number of characters in a string? That's very simple

Dim strWord As String
Dim lngNumberOfCharacters as Long

strWord = "habit"
lngNumberOfCharacters = Len(strWord)
Debug.Print lngNumberOfCharacters

Is there any way you could programatically apply a class to the object?

<object class="hasparams">

then do

object.hasparams

Try the following suggestions:

1. Your machine may have a static IP; map this IP to the hosts file as localhost.
2. Try to log in from your computer or within the network via mysql command; if login is successful, it means that MySQL runs fine.

I'm going to leave this one here: https://stackoverflow.com/a/14509697/1356953

Please note that this works with java.lang.SuppressWarningsso no need to use a separate annotation.

@SuppressWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressWarnings("UWF_NULL_FIELD") String s = null; I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

HTML CODE:

<input type="radio" name="rdoName" value="YES"/> <input type="radio" name="rdoName" value="NO"/>

JQUERY CODE:

var value= $("input:radio[name=rdoName]:checked").val();

$("#btnSubmit").click(function(){_x000D_
var value=$("input:radio[name=rdoName]:checked").val();_x000D_
console.log(value);_x000D_
alert(value);_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="radio" name="rdoName" value="YES"/> YES_x000D_
<input type="radio" name="rdoName" value="NO"/> NO_x000D_
<br/>_x000D_
<input type="button"id="btnSubmit"value="Which one Selected"/>

You will get

value="YES" //if checked Radio Button with the value "YES"
value="NO" //if checked Radio Button with the value "NO"

Because i feel it's really called for, i just want to state some rules of C and C++ (they are the same in this regard). First, all bits of unsigned char participate in determining the value if any unsigned char object. Second, unsigned char is explicitly stated unsigned.

Now, i had a discussion with someone about what happens when you convert the value -1 of type int to unsigned char. He refused the idea that the resulting unsigned char has all its bits set to 1, because he was worried about sign representation. But he don't have to. It's immediately following out of this rule that the conversion does what is intended:

If the new type is unsigned, the value is converted by repeatedly adding or subtracting one more than the maximum value that can be represented in the new type until the value is in the range of the new type. (6.3.1.3p2 in a C99 draft)

That's a mathematical description. C++ describes it in terms of modulo calculus, which yields to the same rule. Anyway, what is not guaranteed is that all bits in the integer -1 are one before the conversion. So, what do we have so we can claim that the resulting unsigned char has all its CHAR_BIT bits turned to 1?

1. All bits participate in determining its value - that is, no padding bits occur in the object.
2. Adding only one time UCHAR_MAX+1 to -1 will yield a value in range, namely UCHAR_MAX

That's enough, actually! So whenever you want to have an unsigned char having all its bits one, you do

unsigned char c = (unsigned char)-1;

It also follows that a conversion is not just truncating higher order bits. The fortunate event for two's complement is that it is just a truncation there, but the same isn't necessarily true for other sign representations.

import java.util.ArrayList;
import java.util.List;

class ArrLst{

    public static void main(String args[]){

        List l=new ArrayList();
        l.add(10);
        l.add(11);
        l.add(12);
        l.add(13);
        l.add(14);
        l.forEach((a)->System.out.println(a));
    }
}

// Month here is 1-indexed (January is 1, February is 2, etc). This is
// because we're using 0 as the day so that it returns the last day
// of the last month, so you have to add 1 to the month number 
// so it returns the correct amount of days
function daysInMonth (month, year) {
    return new Date(year, month, 0).getDate();
}

// July
daysInMonth(7,2009); // 31
// February
daysInMonth(2,2009); // 28
daysInMonth(2,2008); // 29

I had many users controls but one refused to show in the Toolbox, even though I rebuilt the solution and it was checked in the Choose Items... dialog.

Solution:

1. From Solution Explorer I Right-Clicked the offending user control file and selected Exclude From Project
2. Rebuild the solution
3. Right-Click the user control and select Include in Project (assuming you have the Show All Files enabled in the Solution Explorer)

Note this also requires you have the AutoToolboxPopulate option enabled. As @DaveF answer suggests.

Alternate Solution: I'm not sure if this works, and I couldn't try it since I already resolved my issue, but if you unchecked the user control from the Choose Items... dialog, hit OK, then opened it back up and checked the user control. That might also work.

I feel we had a related discussion earlier: How to upload preview image before upload through JavaScript

Adding to Rob?'s answer: in case you want to print rather large numbers, using thousand separators can be a great help (note the comma).

>>> f'{a*1000:,.2f}'
'10,123.40'

Use the steps given in this link. It worked for me.

Step - 1 Right click on your project in Eclipse

Step - 2 Click Properties

Step - 3 Select Maven in the left hand side list.

Step - 4 You will notice "pom.xml" in the Active Maven Profiles text box on the right hand side. Clear it and click Apply.

Step - 5 Run As -> Maven clean -> Maven Install

Hope it helps!

Same solution worked as suggested by hpereira The issue was due to JRE version was 32 bit and not 64 Bit Check with java -version to see if your Java is 64 bit

C:\>java -version
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) **64-Bit Server** VM (build 25.192-b12, mixed mode)

You can launch apps using open:

open -a APP_YOU_WANT

This should open the application that you want.

I had a similar problem this was my code:

    json_file=json.dumps(pyJson)
    file = open("list.json",'w')
    file.write(json_file)  

    json_file = open("list.json","r")
    json_decoded = json.load(json_file)
    print json_decoded

the problem was i had forgotten to file.close() I did it and fixed the problem.

You can compile your C programs with an ARM cross-compiler:

arm-linux-gnueabi-gcc -static -march=armv7-a test.c -o test

Then you can push your compiled binary file to somewhere (don't push it in to the SD card):

adb push test /data/local/tmp/test

You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable

page1.php

<?php

   session_start();
   $_SESSION['superhero'] = "batman";

?>
<a href="page2.php" title="">Go to the other page</a>

page2.php

<?php 

   session_start(); // this NEEDS TO BE AT THE TOP of the page before any output etc
   echo $_SESSION['superhero'];

?>

I'm using GIMP 2.8.1. I hope this will work for you:

Open the "Windows" menu and select "Single-Window Mode".

Simple ;)

Suppose you are calling a web service using HttpWebRequest and HttpWebResponse, because .Net client doest support the structure of the WSLD that your are trying to consume.

In that case you can add the security credentials on the headers like:

<soap:Envelpe>
<soap:Header>
    <wsse:Security soap:mustUnderstand='true' xmlns:wsse='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd' xmlns:wsu='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd'><wsse:UsernameToken wsu:Id='UsernameToken-3DAJDJSKJDHFJASDKJFKJ234JL2K3H2K3J42'><wsse:Username>YOU_USERNAME/wsse:Username><wsse:Password Type='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText'>YOU_PASSWORD</wsse:Password><wsse:Nonce EncodingType='http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary'>3WSOKcKKm0jdi3943ts1AQ==</wsse:Nonce><wsu:Created>2015-01-12T16:46:58.386Z</wsu:Created></wsse:UsernameToken></wsse:Security>
</soapHeather>
<soap:Body>
</soap:Body>


</soap:Envelope>

You can use SOAPUI to get the wsse Security, using the http log.

Be careful because it is not a safe scenario.

I ran into this error after my client PC crashed, the jest --watch command I was running on the server persisted, and I tried to run jest --watch again.

The addition to /etc/sysctl.conf described in the answers above worked around this issue, but it was also important to find my old process via ps aux | grep node and kill it.

This error, as correctly identified above, is due to the compiler not using c++11 or above standard. This answer is for Windows 10.

For c++11 and above standard support in codeblocks version 17:

1. Click settings in the toolbar.

2. A drop-down menu appears. Select compiler option.

3. Choose Global Compiler Settings.

4. In the toolbar in this new window in second section, choose compiler settings.

5. Then choose compiler flags option in below toolbar.

6. Unfold general tab. Check the C++ standard that you want your compiler to follow.

7. Click OK.

For those who are trying to get C++11 support in Sublime text.

1. Download mingw compiler version 7 or above. In versions below this, the default c++ standard used is c++98 whereas in versions higher than 7, the default standard used is c++11.

2. Copy the folder in main C drive. It should not be inside any other folder in C drive.

3. Rename the folder as MinGW. This name is case insensitive, so it should any variation of mingw and must not include any other characters in the name.

4. Then go to environment variables and edit the path variable. Add this "C:\mingw\bin" and click OK.

5. You can check the version of g++ in cmd by typing g++ -v.

6. This should be sufficient to enable c++11 in sublime text.

If you want to take inputs and outputs as well from input files for competitive programming purposes, then follow this link.

The literal 0 has two meanings in C++.
On the one hand, it is an integer with the value 0.
On the other hand, it is a null-pointer constant.

As your setval function can accept either an int or a char*, the compiler can not decide which overload you meant.

The easiest solution is to just cast the 0 to the right type.
Another option is to ensure the int overload is preferred, for example by making the other one a template:

class huge
{
 private:
  unsigned char data[BYTES];
 public:
  void setval(unsigned int);
  template <class T> void setval(const T *); // not implemented
  template <> void setval(const char*);
};

This also handles the keyboard activation.

    private void dgvApps_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        if(dgvApps.CurrentCell.GetType() == typeof(DataGridViewCheckBoxCell))
        {
            if (dgvApps.CurrentCell.IsInEditMode)
            {
                if (dgvApps.IsCurrentCellDirty)
                {
                    dgvApps.EndEdit();
                }
            }
        }
    }


    private void dgvApps_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
          // handle value changed.....
    }

Here's a much newer Kotlin solution for this which is much simpler than many of the answers written here, it uses anonymous class.

val items = mutableListOf<String>()

inner class ItemHolder(view: View): RecyclerView.ViewHolder(view) {
    var textField: TextView = view.findViewById(android.R.id.text1) as TextView
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    rvitems.layoutManager = LinearLayoutManager(context)
    rvitems.adapter = object : RecyclerView.Adapter<ItemHolder>() {

        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ItemHolder {
            return ItemHolder(LayoutInflater.from(parent.context).inflate(android.R.layout.simple_list_item_1, parent, false))
        }

        override fun getItemCount(): Int {
            return items.size
        }

        override fun onBindViewHolder(holder: ItemHolder, position: Int) {
            holder.textField.text = items[position]
            holder.textField.setOnClickListener {
                Toast.makeText(context, "Clicked $position", Toast.LENGTH_SHORT).show()
            }
        }
    }
}

I took the liberty to use android.R.layout.simple_list_item_1 as it's simpler. I wanted to simplify it even further and put ItemHolder as an inner class but couldn't quite figure out how to reference it in a type in the outer class parameter.

Positional Arguments

They have no keywords before them. The order is important!

func(1,2,3, "foo")

Keyword Arguments

They have keywords in the front. They can be in any order!

func(foo="bar", baz=5, hello=123)

func(baz=5, foo="bar", hello=123)

You should also know that if you use default arguments and neglect to insert the keywords, then the order will then matter!

def func(foo=1, baz=2, hello=3): ...
func("bar", 5, 123)

If you prefer to use annotations to selectively silence rules, this is now possible using the @SuppressWarnings annotation, starting with Checkstyle 5.7 (and supported by the Checkstyle Maven Plugin 2.12+).

First, in your checkstyle.xml, add the SuppressWarningsHolder module to the TreeWalker:

<module name="TreeWalker">
    <!-- Make the @SuppressWarnings annotations available to Checkstyle -->
    <module name="SuppressWarningsHolder" />
</module>

Next, enable the SuppressWarningsFilter there (as a sibling to TreeWalker):

<!-- Filter out Checkstyle warnings that have been suppressed with the @SuppressWarnings annotation -->
<module name="SuppressWarningsFilter" />

<module name="TreeWalker">
...

Now you can annotate e.g. the method you want to exclude from a certain Checkstyle rule:

@SuppressWarnings("checkstyle:methodlength")
@Override
public boolean equals(Object obj) {
    // very long auto-generated equals() method
}

The checkstyle: prefix in the argument to @SuppressWarnings is optional, but I like it as a reminder where this warning came from. The rule name must be lowercase.

Lastly, if you're using Eclipse, it will complain about the argument being unknown to it:

Unsupported @SuppressWarnings("checkstyle:methodlength")

You can disable this Eclipse warning in the preferences if you like:

Preferences:
  Java
  --> Compiler
  --> Errors/Warnings
  --> Annotations
  --> Unhandled token in '@SuppressWarnings': set to 'Ignore'

For example you have a start program named run.sh to start it working at background do the following command line. ./run.sh &>/dev/null &

I'm adding this as a response to explain where the constraint comes from. I tried to do it in the comments but it's hard to edit nicely there :-/

If you create (or alter) a table with a column that has default values it will create the constraint for you.

In your table for example it might be:

CREATE TABLE Movie (
    ...
    rating INT NOT NULL default 100
)

It will create the constraint for default 100.

If you instead create it like so

CREATE TABLE Movie (
  name VARCHAR(255) NOT NULL,
  rating INT NOT NULL CONSTRAINT rating_default DEFAULT 100
);

Then you get a nicely named constraint that's easier to reference when you are altering said table.

ALTER TABLE Movie DROP CONSTRAINT rating_default;
ALTER TABLE Movie ALTER COLUMN rating DECIMAL(2) NOT NULL;
-- sets up a new default constraint with easy to remember name
ALTER TABLE Movie ADD CONSTRAINT rating_default DEFAULT ((1.0)) FOR rating;

You can combine those last 2 statements so you alter the column and name the constraint in one line (you have to if it's an existing table anyways)

I was facing the same issue. After researching too much on Google and StackOverflow. I found a solution very simple

First, you need to set environment like this

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=example44
MAIL_ENCRYPTION=tls
[email protected]

you have to change your Gmail address and password

Now you have to on less secure apps by following this link https://myaccount.google.com/lesssecureapps

parent.abc() will only work on same domain due to security purposes. i tried this workaround and mine worked perfectly.

<head>
    <script>
    function abc() {
        alert("sss");
    }

    // window of the iframe
    var innerWindow = document.getElementById('myFrame').contentWindow;
    innerWindow.abc= abc;

    </script>
</head>
<body>
    <iframe id="myFrame">
        <a onclick="abc();" href="#">Click Me</a>
    </iframe>
</body>

Hope this helps. :)

For me, the only thing which worked is

git diff HEAD

including the staged files, git diff --cached only shows staged files.

This worked for me in Luna elementary OS

sudo apt-get install libxtst6:i386

This would also happen if there is/are any additional folder/files in resource folder which are not supported by Android.

Updated answer using readxl (22nd June 2015)

Since posting this question the readxl package has been released. It supports both xls and xlsx format. Importantly, in contrast to other excel import packages, it works on Windows, Mac, and Linux without requiring installation of additional software.

So a function for importing all sheets in an Excel workbook would be:

library(readxl)    
read_excel_allsheets <- function(filename, tibble = FALSE) {
    # I prefer straight data.frames
    # but if you like tidyverse tibbles (the default with read_excel)
    # then just pass tibble = TRUE
    sheets <- readxl::excel_sheets(filename)
    x <- lapply(sheets, function(X) readxl::read_excel(filename, sheet = X))
    if(!tibble) x <- lapply(x, as.data.frame)
    names(x) <- sheets
    x
}

This could be called with:

mysheets <- read_excel_allsheets("foo.xls")

Old Answer

Building on the answer provided by @mnel, here is a simple function that takes an Excel file as an argument and returns each sheet as a data.frame in a named list.

library(XLConnect)

importWorksheets <- function(filename) {
    # filename: name of Excel file
    workbook <- loadWorkbook(filename)
    sheet_names <- getSheets(workbook)
    names(sheet_names) <- sheet_names
    sheet_list <- lapply(sheet_names, function(.sheet){
        readWorksheet(object=workbook, .sheet)})
}

Thus, it could be called with:

importWorksheets('test.xls')

I got the same error, and because I have 4 ssh-keys, so I tried follow:

ssh-keygen -t rsa
heroku keys:add

then, four options show:

1) github_rsa.pub
2) id_boot2docker.pub
3) id_rsa.pub
4) sshkey.pub

I choose 3), the newest one

Then, I fix the error.

Try the following:

SELECT DISTINCT(ip), name, COUNT(name) nameCnt, 
time, price, SUM(price) priceSum
FROM tablename 
WHERE time >= $yesterday AND time <$today 
GROUP BY ip, name

If you use Sublime Text on Windows or Mac to edit your scripts:

Click on View > Line Endings > Unix and save the file again.

When you have Overridden Methods with same Name Use the helper below

public static TValue GetControllerMethodAttributeValue<T, TT, TAttribute, TValue>(this T type, Expression<Func<T, TT>> exp, Func<TAttribute, TValue> valueSelector) where TAttribute : Attribute
        {
            var memberExpression = exp?.Body as MethodCallExpression;

            if (memberExpression.Method.GetCustomAttributes(typeof(TAttribute), false).FirstOrDefault() is TAttribute attr && valueSelector != null)
            {
                return valueSelector(attr);
            }

            return default(TValue);
        }

Usage: var someController = new SomeController(Some params); var str = typeof(SomeController).GetControllerMethodAttributeValue(x => someController.SomeMethod(It.IsAny()), (RouteAttribute routeAttribute) => routeAttribute.Template);

Call clear() method from your custom adapter .

Acording with the documentation, the method getEntity in Jax rs 2.0 return a InputStream. If you need to convert to InputStream to String with JSON format, you need to cast the two formats. For example in my case, I implemented the next method:

    private String processResponse(Response response) {
    if (response.getEntity() != null) {
        try {
            InputStream salida = (InputStream) response.getEntity();
            StringWriter writer = new StringWriter();
            IOUtils.copy(salida, writer, "UTF-8");
            return writer.toString();
        } catch (IOException ex) {
            LOG.log(Level.SEVERE, null, ex);
        }
    }
    return null;
}

why I implemented this method. Because a read in differets blogs that many developers they have the same problem whit the version in jaxrs using the next methods

String output = response.readEntity(String.class)

and

String output = response.getEntity(String.class)

The first works using jersey-client from com.sun.jersey library and the second found using the jersey-client from org.glassfish.jersey.core.

This is the error that was being presented to me: org.glassfish.jersey.client.internal.HttpUrlConnector$2 cannot be cast to java.lang.String

I use the following maven dependency:

<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.28</version>

What I do not know is why the readEntity method does not work.I hope you can use the solution.

If you want to return a date type as just a date use

CONVERT(date, SYSDATETIME())

or

SELECT CONVERT(date,SYSDATETIME()) 

or

DECLARE @DateOnly Datetime
SET @DateOnly=CONVERT(date,SYSDATETIME())

I think the best way I've seen it done is multiplying by 10 to the power of the number of digits, then doing a Math.round, then finally dividing by 10 to the power of digits. Here is a simple function I use in typescript:

function roundToXDigits(value: number, digits: number) {
    value = value * Math.pow(10, digits);
    value = Math.round(value);
    value = value / Math.pow(10, digits);
    return value;
}

Or plain javascript:

function roundToXDigits(value, digits) {
    if(!digits){
        digits = 2;
    }
    value = value * Math.pow(10, digits);
    value = Math.round(value);
    value = value / Math.pow(10, digits);
    return value;
}

If you're going to reuse the value like an id or if you want to just keep it you can add a "new{id = 'desiredID/value'}) as its parameters so you can access the value thru jquery/javascript

@Html.HiddenFor(model => model.Car_id)

An add-on to the previous answers since I came across this concern:

If you really want to insert something like 24-May-2005 to your DATE column, you could do something like this:

INSERT INTO someTable(Empid,Date_Joined)
VALUES
    ('S710',STR_TO_DATE('24-May-2005', '%d-%M-%Y'));

In the above query please note that if it's May(ie: the month in letters) the format should be %M.

NOTE: I tried this with the latest MySQL version 8.0 and it works!

Check out php.ini the value set for session.gc_maxlifetime is the ID lifetime in seconds.

I believe the default is 1440 seconds (24 mins)

http://www.php.net/manual/en/session.configuration.php

Edit: As some comments point out, the above is not entirely accurate. A wonderful explanation of why, and how to implement session lifetimes is available here:

How do I expire a PHP session after 30 minutes?

As unwind noted, keyword arguments with default values can go a long way.

I'll also state that in my opinion, it goes against the spirit of Python to worry a lot about what types are passed into methods. In Python, I think it's more accepted to use duck typing -- asking what an object can do, rather than what it is.

Thus, if your method may accept a string or a tuple, you might do something like this:

def print_names(names):
    """Takes a space-delimited string or an iterable"""
    try:
        for name in names.split(): # string case
            print name
    except AttributeError:
        for name in names:
            print name

Then you could do either of these:

print_names("Ryan Billy")
print_names(("Ryan", "Billy"))

Although an API like that sometimes indicates a design problem.

I think you should give the data types of the column as NUMERIC or DOUBLE or FLOAT or REAL

Read http://sqlite.org/datatype3.html to more info.

If by the type of a variable you mean the runtime class of the object that the variable points to, then you can get this through the class reference that all objects have.

val name = "sam";
name: java.lang.String = sam
name.getClass
res0: java.lang.Class[_] = class java.lang.String

If you however mean the type that the variable was declared as, then you cannot get that. Eg, if you say

val name: Object = "sam"

then you will still get a String back from the above code.

A previous answer using LPAD() is optimal. However, in the event you want to do special or advanced processing, here is a method that allows more iterative control over the padding. Also serves as an example using other constructs to achieve the same thing.

UPDATE
    mytable
SET
    mycolumn = CONCAT(
        REPEAT(
            "0",
            8 - LENGTH(mycolumn)
        ),
        mycolumn
    )
WHERE
    LENGTH(mycolumn) < 8;

While SimpleXML provides a way to remove XML nodes, its modification capabilities are somewhat limited. One other solution is to resort to using the DOM extension. dom_import_simplexml() will help you with converting your SimpleXMLElement into a DOMElement.

Just some example code (tested with PHP 5.2.5):

$data='<data>
    <seg id="A1"/>
    <seg id="A5"/>
    <seg id="A12"/>
    <seg id="A29"/>
    <seg id="A30"/>
</data>';
$doc=new SimpleXMLElement($data);
foreach($doc->seg as $seg)
{
    if($seg['id'] == 'A12') {
        $dom=dom_import_simplexml($seg);
        $dom->parentNode->removeChild($dom);
    }
}
echo $doc->asXml();

outputs

<?xml version="1.0"?>
<data><seg id="A1"/><seg id="A5"/><seg id="A29"/><seg id="A30"/></data>

By the way: selecting specific nodes is much more simple when you use XPath (SimpleXMLElement->xpath):

$segs=$doc->xpath('//seq[@id="A12"]');
if (count($segs)>=1) {
    $seg=$segs[0];
}
// same deletion procedure as above

async methods are different than normal methods. Whatever you return from async methods are wrapped in a Task.

If you return no value(void) it will be wrapped in Task, If you return int it will be wrapped in Task<int> and so on.

If your async method needs to return int you'd mark the return type of the method as Task<int> and you'll return plain int not the Task<int>. Compiler will convert the int to Task<int> for you.

private async Task<int> MethodName()
{
    await SomethingAsync();
    return 42;//Note we return int not Task<int> and that compiles
}

Sameway, When you return Task<object> your method's return type should be Task<Task<object>>

public async Task<Task<object>> MethodName()
{
     return Task.FromResult<object>(null);//This will compile
}

Since your method is returning Task, it shouldn't return any value. Otherwise it won't compile.

public async Task MethodName()
{
     return;//This should work but return is redundant and also method is useless.
}

Keep in mind that async method without an await statement is not async.

Plain Java 8 solutions using a Stream.

Constant number

Assuming private Collection<T> c, c2, c3.

One solution:

public Stream<T> stream() {
    return Stream.concat(Stream.concat(c.stream(), c2.stream()), c3.stream());
}

Another solution:

public Stream<T> stream() {
    return Stream.of(c, c2, c3).flatMap(Collection::stream);
}

Variable number

Assuming private Collection<Collection<T>> cs:

public Stream<T> stream() {
    return cs.stream().flatMap(Collection::stream);
}

The head command can get the first n lines. Variations are:

head -7 file
head -n 7 file
head -7l file

which will get the first 7 lines of the file called "file". The command to use depends on your version of head. Linux will work with the first one.

To append lines to the end of the same file, use:

echo 'first line to add' >>file
echo 'second line to add' >>file
echo 'third line to add' >>file

or:

echo 'first line to add
second line to add
third line to add' >>file

to do it in one hit.

So, tying these two ideas together, if you wanted to get the first 10 lines of the input.txt file to output.txt and append a line with five "=" characters, you could use something like:

( head -10 input.txt ; echo '=====' ) > output.txt

In this case, we do both operations in a sub-shell so as to consolidate the output streams into one, which is then used to create or overwrite the output file.

You can use np.where to match the boolean conditions corresponding to Nan values of the array and map each outcome to generate a list of tuples.

>>>list(map(tuple, np.where(np.isnan(x))))
[(1, 2), (2, 0)]

In Go 1.10+ there is strings.Builder, here.

A Builder is used to efficiently build a string using Write methods. It minimizes memory copying. The zero value is ready to use.

Example

It's almost the same with bytes.Buffer.

package main

import (
    "strings"
    "fmt"
)

func main() {
    // ZERO-VALUE:
    //
    // It's ready to use from the get-go.
    // You don't need to initialize it.
    var sb strings.Builder

    for i := 0; i < 1000; i++ {
        sb.WriteString("a")
    }

    fmt.Println(sb.String())
}

Click to see this on the playground.

Supported Interfaces

StringBuilder's methods are being implemented with the existing interfaces in mind. So that you can switch to the new Builder type easily in your code.

• Grow(int) -> bytes.Buffer#Grow
• Len() int -> bytes.Buffer#Len
• Reset() -> bytes.Buffer#Reset
• String() string -> fmt.Stringer
• Write([]byte) (int, error) -> io.Writer
• WriteByte(byte) error -> io.ByteWriter
• WriteRune(rune) (int, error) -> bufio.Writer#WriteRune - bytes.Buffer#WriteRune
• WriteString(string) (int, error) -> io.stringWriter

Differences from bytes.Buffer

• It can only grow or reset.

• It has a copyCheck mechanism built-in that prevents accidentially copying it:

  func (b *Builder) copyCheck() { ... }

• In bytes.Buffer, one can access the underlying bytes like this: (*Buffer).Bytes().

  • strings.Builder prevents this problem.
  • Sometimes, this is not a problem though and desired instead.
  • For example: For the peeking behavior when the bytes are passed to an io.Reader etc.

• bytes.Buffer.Reset() rewinds and reuses the underlying buffer whereas the strings.Builder.Reset() does not, it detaches the buffer.

Note

• Do not copy a StringBuilder value as it caches the underlying data.
• If you want to share a StringBuilder value, use a pointer to it.

Check out its source code for more details, here.

• Creation var div = document.createElement('div');
• Addition document.body.appendChild(div);
• Style manipulation
  • Positioning div.style.left = '32px'; div.style.top = '-16px';
  • Classes div.className = 'ui-modal';
• Modification
  • ID div.id = 'test';
  • contents (using HTML) div.innerHTML = '<span class="msg">Hello world.</span>';
  • contents (using text) div.textContent = 'Hello world.';
• Removal div.parentNode.removeChild(div);
• Accessing
  • by ID div = document.getElementById('test');
  • by tags array = document.getElementsByTagName('div');
  • by class array = document.getElementsByClassName('ui-modal');
  • by CSS selector (single) div = document.querySelector('div #test .ui-modal');
  • by CSS selector (multi) array = document.querySelectorAll('div');
• Relations (text nodes included)
  • children node = div.childNodes[i];
  • sibling node = div.nextSibling;
• Relations (HTML elements only)
  • children element = div.children[i];
  • sibling element = div.nextElementSibling;

This covers the basics of DOM manipulation. Remember, element addition to the body or a body-contained node is required for the newly created node to be visible within the document.

Use getopt

Why getopt?

To parse elaborated command-line arguments to avoid confusion and clarify the options we are parsing so that reader of the commands can understand what's happening.

What is getopt?

getopt is used to break up (parse) options in command lines for easy parsing by shell procedures, and to check for legal options. It uses the GNU getopt(3) routines to do this.

getopt can have following types of options.

1. No-value options
2. key-value pair options

Note: In this document, during explaining syntax:

• Anything inside [ ] is optional parameter in the syntax/examples.
• is a place holder, which mean it should be substituted with an actual value.

HOW TO USE getopt?

Syntax: First Form

getopt optstring parameters

Examples:

# This is correct
getopt "hv:t::" "-v 123 -t123"  
getopt "hv:t::" "-v123 -t123"  # -v and 123 doesn't have whitespace

# -h takes no value.
getopt "hv:t::" "-h -v123"


# This is wrong. after -t can't have whitespace.
# Only optional params cannot have whitespace between key and value
getopt "hv:t::" "-v 123 -t 123"

# Multiple arguments that takes value.
getopt "h:v:t::g::" "-h abc -v 123 -t21"

# Multiple arguments without value
# All of these are correct
getopt "hvt" "-htv"
getopt "hvt" "-h -t -v"
getopt "hvt" "-tv -h"

Here h,v,t are the options and -h -v -t is how options should be given in command-line.

1. 'h' is a no-value option.
2. 'v:' implies that option -v has value and is a mandatory option. ':' means has a value.
3. 't::' implies that option -t has value but is optional. '::' means optional.

In optional param, value cannot have whitespace separation with the option. So, in "-t123" example, -t is option 123 is value.

Syntax: Second Form

getopt [getopt_options] [--] [optstring] [parameters]

Here after getopt is split into five parts

• The command itself i.e. getopt
• The getopt_options, it describes how to parse the arguments. single dash long options, double dash options.
• --, separates out the getopt_options from the options you want to parse and the allowed short options
• The short options, is taken immediately after -- is found. Just like the Form first syntax.
• The parameters, these are the options that you have passed into the program. The options you want to parse and get the actual values set on them.

Examples

getopt -l "name:,version::,verbose" -- "n:v::V" "--name=Karthik -version=5.2 -verbose"

Syntax: Third Form

getopt [getopt_options] [-o options] [--] [optstring] [parameters]

Here after getopt is split into five parts

• The command itself i.e. getopt
• The getopt_options, it describes how to parse the arguments. single dash long options, double dash options.
• The short options i.e. -o or --options. Just like the Form first syntax but with option "-o" and before the "--" (double dash).
• --, separates out the getopt_options from the options you want to parse and the allowed short options
• The parameters, these are the options that you have passed into the program. The options you want to parse and get the actual values set on them.

Examples

getopt -l "name:,version::,verbose" -a -o "n:v::V" -- "-name=Karthik -version=5.2 -verbose"

GETOPT_OPTIONS

getopt_options changes the way command-line params are parsed.

Below are some of the getopt_options

Option: -l or --longoptions

Means getopt command should allow multi-character options to be recognised. Multiple options are separated by comma.

For example, --name=Karthik is a long option sent in command line. In getopt, usage of long options are like

getopt "name:,version" "--name=Karthik"

Since name: is specified, the option should contain a value

Option: -a or --alternative

Means getopt command should allow long option to have a single dash '-' rather than double dash '--'.

Example, instead of --name=Karthik you could use just -name=Karthik

getopt "name:,version" "-name=Karthik"

A complete script example with the code:

#!/bin/bash

# filename: commandLine.sh
# author: @theBuzzyCoder

showHelp() {
# `cat << EOF` This means that cat should stop reading when EOF is detected
cat << EOF  
Usage: ./installer -v <espo-version> [-hrV]
Install Pre-requisites for EspoCRM with docker in Development mode

-h, -help,          --help                  Display help

-v, -espo-version,  --espo-version          Set and Download specific version of EspoCRM

-r, -rebuild,       --rebuild               Rebuild php vendor directory using composer and compiled css using grunt

-V, -verbose,       --verbose               Run script in verbose mode. Will print out each step of execution.

EOF
# EOF is found above and hence cat command stops reading. This is equivalent to echo but much neater when printing out.
}


export version=0
export verbose=0
export rebuilt=0

# $@ is all command line parameters passed to the script.
# -o is for short options like -v
# -l is for long options with double dash like --version
# the comma separates different long options
# -a is for long options with single dash like -version
options=$(getopt -l "help,version:,verbose,rebuild,dryrun" -o "hv:Vrd" -a -- "$@")

# set --:
# If no arguments follow this option, then the positional parameters are unset. Otherwise, the positional parameters 
# are set to the arguments, even if some of them begin with a ‘-’.
eval set -- "$options"

while true
do
case $1 in

    export rebuild=1
    ;;

done

Running this script file:

# With short options grouped together and long option
# With double dash '--version'

bash commandLine.sh --version=1.0 -rV
# With short options grouped together and long option
# With single dash '-version'

bash commandLine.sh -version=1.0 -rV

# OR with short option that takes value, value separated by whitespace

bash commandLine.sh -v 1.0 -rV

# OR with short option that takes value, value without whitespace
# separation from key.

bash commandLine.sh -v1.0 -rV

# OR Separating individual short options

bash commandLine.sh -v1.0 -r -V

Remember that @@IDENTITY returns the most recently created identity for your current connection, not necessarily the identity for the recently added row in a table. You should always use SCOPE_IDENTITY() to return the identity of the recently added row.

I use .forEach to iterate over , and push result to results array then use it, with this solution I will not loop over array twice

Even without pop the list we can do with set_index

pd.DataFrame(table).T.set_index(0).T
Out[11]: 
0 Heading1 Heading2
1        1        2
2        3        4

Update from_records

table = [['Heading1', 'Heading2'], [1 , 2], [3, 4]]

pd.DataFrame.from_records(table[1:],columns=table[0])
Out[58]: 
   Heading1  Heading2
0         1         2
1         3         4

In our case it was an empty AndroidManifest.xml.

While upgrading Eclispe we ran into the usual trouble, and AndroidManifest.xml must have been checked into SVN by the build script after being clobbered.

Found it by compiling from inside Eclipse, instead of from the command line.

My reputation being too small to comment an answer, here is my feedback concerning roquen answer (using settings on xmlwriter to force the stream to close): it works perfectly and it made me save a lot of time. roquen's example requires some adjustment, here is the code that works on .NET framework 4.8 :

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.CloseOutput = true;
    writer = XmlWriter.Create(stream, settings);

dropdownlist.ClearSelection(); //making sure the previous selection has been cleared
dropdownlist.Items.FindByValue(value).Selected = true;

You have to create sortDescriptor and then you can sort the nsmutablearray by using sortDescriptor like below.

 let sortDescriptor = NSSortDescriptor(key: "birthDate", ascending: true, selector: #selector(NSString.compare(_:)))
 let array = NSMutableArray(array: self.aryExist.sortedArray(using: [sortDescriptor]))
 print(array)

SELECT * FROM table WHERE field1 NOT LIKE '%$x%'; (Make sure you escape $x properly beforehand to avoid SQL injection)

Edit: NOT IN does something a bit different - your question isn't totally clear so pick which one to use. LIKE 'xxx%' can use an index. LIKE '%xxx' or LIKE '%xxx%' can't.

You could simply apply one of the bootstrap contextual background colors to the header row. In this case (blue background, white text): primary.

You can try this

ISNUMERIC (Transact-SQL)

ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.

DECLARE @Table TABLE(

INSERT INTO @Table SELECT '2' 
INSERT INTO @Table SELECT 'Lions'

SELECT  *

Sometimes a dependency added with ng add will add more than one package, typing npm uninstall lib1 lib2 could be error prone and slow, so just remove the not needed libraries from package.json and run npm i

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

Update June 2016

Felt compelled to add an answer having seen far too many SOF answers with dated or inadequate answers to very common problem - a good library and some solid example usage for both parse and format operations.

Use org.apache.httpcomponents.httpclient library. The library contains this org.apache.http.client.utils.URLEncodedUtils class utility.

For example, it is easy to download this dependency from Maven:

 <dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5</version>
 </dependency>

For my purposes I only needed to parse (read from query string to name-value pairs) and format (read from name-value pairs to query string) query strings. However, there are equivalents for doing the same with a URI (see commented out line below).

// Required imports

import org.apache.http.NameValuePair;
import org.apache.http.client.utils.URLEncodedUtils;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.nio.charset.StandardCharsets;

// code snippet

public static void parseAndFormatExample() throws UnsupportedEncodingException {
        final String queryString = "nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk";
        System.out.println(queryString);
        // => nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk

        final List<NameValuePair> params =
                URLEncodedUtils.parse(queryString, StandardCharsets.UTF_8);
        // List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), "UTF-8");

        for (final NameValuePair param : params) {
            System.out.println(param.getName() + " : " + param.getValue());
            // => nonce : 12345
            // => redirectCallbackUrl : http://www.bbc.co.uk
        }

        final String newQueryStringEncoded =
                URLEncodedUtils.format(params, StandardCharsets.UTF_8);


        // decode when printing to screen
        final String newQueryStringDecoded =
                URLDecoder.decode(newQueryStringEncoded, StandardCharsets.UTF_8.toString());
        System.out.println(newQueryStringDecoded);
        // => nonce=12345&redirectCallbackUrl=http://www.bbc.co.uk
    }

This library did exactly what I needed and was able to replace some hacked custom code.

you have to tell angular that you updated the content after ngAfterContentChecked you can import ChangeDetectorRef from @angular/core and call detectChanges

import {ChangeDetectorRef } from '@angular/core';

constructor( private cdref: ChangeDetectorRef ) {}


ngAfterContentChecked() {

this.sampleViewModel.DataContext = this.DataContext;
this.sampleViewModel.Position = this.Position;
this.cdref.detectChanges();

 }

If you want to delete document according to a date. You can use kibana console (v.6.1.2)

POST index_name/_delete_by_query
{
      "query" : {
              "range" : {
                 "sendDate" : {
                     "lte" : "2018-03-06"
                              }
                        }
                  }
}

I know this is late but it is very simple.All you have do is let your class implement Serializable like

public class MyClass implements Serializable{

}

then you can pass to an intent like

Intent intent=......
MyClass obje=new MyClass();
intent.putExtra("someStringHere",obje);

To get it you simpley call

MyClass objec=(MyClass)intent.getExtra("theString");

There are two Things you can do

use

int noOfColumns = sh.getRow(0).getPhysicalNumberOfCells();

or

int noOfColumns = sh.getRow(0).getLastCellNum();

There is a fine difference between them

1. Option 1 gives the no of columns which are actually filled with contents(If the 2nd column of 10 columns is not filled you will get 9)
2. Option 2 just gives you the index of last column. Hence done 'getLastCellNum()'

You can wrap the contents of the li in another element such as a span. Then, give the li a larger font-size, and set a normal font-size back on the span:

http://jsfiddle.net/RZr2r/

li {
    font-size: 36px;
}
li span {
    font-size: 18px;
}
<ul>
    <li><span>Item 1</span></li>
    <li><span>Item 2</span></li>
    <li><span>Item 3</span></li>
</ul>

How about this:

SELECT all_fields.*  
FROM (SELECT id, MAX(rev) FROM yourtable GROUP BY id) AS max_recs  
LEFT OUTER JOIN yourtable AS all_fields 
ON max_recs.id = all_fields.id

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.

Regarding the problem with "Optimize code" property being UNCHECKED yet the code still compiling as optimized: What finally helped me after trying everything was checking the "Enable unmanaged code debugging" checkbox on the same settings page (Project properties - Debug). It doesn't directly relate to the code optimization, but with this enabled, VS no longer optimizes my library and I can debug.

First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:

$container.cycle(id.replace('#',''));

I had the same error, what solve my problem was. In my library instead of using compile or implementation i use "api". So in the end my dependencies:

So I struggled with this and thought I was going mad, the thing is bootstrap datepicker was being implemented not jQuery so teh options were different;

$('.dateInput').datepicker({  format: 'dd/mm/yyyy'})

Probably because the original version of Python (CPython) was written in C, not C++.

The idea that a list is formed by pushing things onto the back of something is probably not as well-known as the thought of appending them.

ComponentWillReceiveProps() is going to be deprecated in the future due to bugs and inconsistencies. An alternative solution for re-rendering a component on props change is to use ComponentDidUpdate() and ShouldComponentUpdate().

ComponentDidUpdate() is called whenever the component updates AND if ShouldComponentUpdate() returns true (If ShouldComponentUpdate() is not defined it returns true by default).

shouldComponentUpdate(nextProps){
    return nextProps.changedProp !== this.state.changedProp;
}

componentDidUpdate(props){
    // Desired operations: ex setting state
}

This same behavior can be accomplished using only the ComponentDidUpdate() method by including the conditional statement inside of it.

componentDidUpdate(prevProps){
    if(prevProps.changedProp !== this.props.changedProp){
        this.setState({          
            changedProp: this.props.changedProp
        });
    }
}

If one attempts to set the state without a conditional or without defining ShouldComponentUpdate() the component will infinitely re-render

If you're using the mysql native driver (common since php 5.3), and the mysqli extension, you can accomplish this with an asynchronous query:

<?php

// Here's an example query that will take a long time to execute.
$sql = "
    select *
    from information_schema.tables t1
    join information_schema.tables t2
    join information_schema.tables t3
    join information_schema.tables t4
    join information_schema.tables t5
    join information_schema.tables t6
    join information_schema.tables t7
    join information_schema.tables t8
";

$mysqli = mysqli_connect('localhost', 'root', '');
$mysqli->query($sql, MYSQLI_ASYNC | MYSQLI_USE_RESULT);
$links = $errors = $reject = [];
$links[] = $mysqli;

// wait up to 1.5 seconds
$seconds = 1;
$microseconds = 500000;

$timeStart = microtime(true);

if (mysqli_poll($links, $errors, $reject, $seconds, $microseconds) > 0) {
    echo "query finished executing. now we start fetching the data rows over the network...\n";
    $result = $mysqli->reap_async_query();
    if ($result) {
        while ($row = $result->fetch_row()) {
            // print_r($row);
            if (microtime(true) - $timeStart > 1.5) {
                // we exceeded our time limit in the middle of fetching our result set.
                echo "timed out while fetching results\n";
                var_dump($mysqli->close());
                break;
            }
        }
    }
} else {
    echo "timed out while waiting for query to execute\n";
    var_dump($mysqli->close());
}

The flags I'm giving to mysqli_query accomplish important things. It tells the client driver to enable asynchronous mode, while forces us to use more verbose code, but lets us use a timeout(and also issue concurrent queries if you want!). The other flag tells the client not to buffer the entire result set into memory.

By default, php configures its mysql client libraries to fetch the entire result set of your query into memory before it lets your php code start accessing rows in the result. This can take a long time to transfer a large result. We disable it, otherwise we risk that we might time out while waiting for the buffering to complete.

Note that there's two places where we need to check for exceeding a time limit:

• The actual query execution
• while fetching the results(data)

You can accomplish similar in the PDO and regular mysql extension. They don't support asynchronous queries, so you can't set a timeout on the query execution time. However, they do support unbuffered result sets, and so you can at least implement a timeout on the fetching of the data.

For many queries, mysql is able to start streaming the results to you almost immediately, and so unbuffered queries alone will allow you to somewhat effectively implement timeouts on certain queries. For example, a

select * from tbl_with_1billion_rows

can start streaming rows right away, but,

select sum(foo) from tbl_with_1billion_rows

needs to process the entire table before it can start returning the first row to you. This latter case is where the timeout on an asynchronous query will save you. It will also save you from plain old deadlocks and other stuff.

ps - I didn't include any timeout logic on the connection itself.

I encountered the following message repeatedly when trying to start SQL Developer from my installation of Oracle Database 11g Enterprise: Enter the full pathname for java.exe.

No matter how many times I browsed to the correct path, I kept being presented with the exact same dialog box. This was in Windows 7, and the solution was to right-click on the SQL Developer icon and select "Run as administrator". I then used this path: C:\app\shellperson\product\11.1.0\db_1\jdk\jre\bin\java.exe

1. Place your image in a div.
2. Give your div explicit square dimensions.
3. Set the CSS overflow property on the div to hidden (overflow:hidden).
4. Put your imagine inside the div.
5. Profit.

For example:

<div style="width:200px;height:200px;overflow:hidden">
    <img src="foo.png" />
</div>

You can either post HTML form to URL, which is mapped to servlet or insert your data in HttpServletRequest object you pass to jsp page.

Try something like this:

SELECT * FROM clients WHERE CONCAT(field1, '', field2, '', fieldn) LIKE "%Mary%"

You may want to see SQL docs for additional information on string operators and regular expressions.

Edit: There may be some issues with NULL fields, so just in case you may want to use IFNULL(field_i, '') instead of just field_i

Case sensitivity: You can use case insensitive collation or something like this:

... WHERE LOWER(CONCAT(...)) LIKE LOWER("%Mary%")

Just search all field: I believe there is no way to make an SQL-query that will search through all field without explicitly declaring field to search in. The reason is there is a theory of relational databases and strict rules for manipulating relational data (something like relational algebra or codd algebra; these are what SQL is from), and theory doesn't allow things such as "just search all fields". Of course actual behaviour depends on vendor's concrete realisation. But in common case it is not possible. To make sure, check SELECT operator syntax (WHERE section, to be precise).

I'm not sure of the git command for it yet, but I think you can find them in the reflogs.

.git/logs/refs/heads/<yourbranch>

My files appear to have a unix timestamp in them.

Update: There appears to be an option to use the reflog history instead of the commit history when printing the logs:

git log -g

You can follow this log as well, back to when you created the branch. git log is showing the date of the commit, though, not the date when you made the action that made an entry in the reflog. I haven't found that yet except by looking in the actual reflog in the path above.

Does SQL Server support analytic functions?

select   rowint,
         value,
         value - lag(value) over (order by rowint) diff
from     myTable
order by rowint
/

Here is an alternative that worked for me:

$('div#somediv').css({'width': '70%'});

If the file is text, you can send it easiest in the body as:

sendmail [email protected] < message.txt

Check this

ps aux | grep "aa.sh"

I know this is an old question, but maybe I can be of help to someone, bc this also stumped me until I read the documentation a bit more:

prevArrow string (html|jQuery selector) | object (DOM node|jQuery object) Previous Allows you to select a node or customize the HTML for the "Previous" arrow.

nextArrow string (html|jQuery selector) | object (DOM node|jQuery object) Next Allows you to select a node or customize the HTML for the "Next" arrow.

this is how i changed my buttons.. worked perfectly.

  $('.carousel-content').slick({
      prevArrow:"<img class='a-left control-c prev slick-prev' src='../images/shoe_story/arrow-left.png'>",
      nextArrow:"<img class='a-right control-c next slick-next' src='../images/shoe_story/arrow-right.png'>"
  });

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

You can add the following line in the values-v21/style.xml folder:

<item name="android:navigationBarColor">@color/theme_color</item>

If id is sequential starting at 1, the simplest (and quickest) would be:

UPDATE `table` 
SET uid = ELT(id, 2952, 4925, 1592) 
WHERE id IN (1,2,3)

As ELT() returns the Nth element of the list of strings: str1 if N = 1, str2 if N = 2, and so on. Returns NULL if N is less than 1 or greater than the number of arguments.

Clearly, the above code only works if id is 1, 2, or 3. If id was 10, 20, or 30, either of the following would work:

UPDATE `table` 
SET uid = CASE id 
WHEN 10 THEN 2952 
WHEN 20 THEN 4925 
WHEN 30 THEN 1592 END CASE 
WHERE id IN (10, 20, 30)

or the simpler:

UPDATE `table` 
SET uid = ELT(FIELD(id, 10, 20, 30), 2952, 4925, 1592) 
WHERE id IN (10, 20, 30)

As FIELD() returns the index (position) of str in the str1, str2, str3, ... list. Returns 0 if str is not found.

If you write Perl with use strict;, then you'll find that the one line syntax isn't valid, even when declared.

With:

my ($newstring = $oldstring) =~ s/foo/bar/;

You get:

Can't declare scalar assignment in "my" at script.pl line 7, near ") =~"
Execution of script.pl aborted due to compilation errors.

Instead, the syntax that you have been using, while a line longer, is the syntactically correct way to do it with use strict;. For me, using use strict; is just a habit now. I do it automatically. Everyone should.

#!/usr/bin/env perl -wT

use strict;

my $oldstring = "foo one foo two foo three";
my $newstring = $oldstring;
$newstring =~ s/foo/bar/g;

print "$oldstring","\n";
print "$newstring","\n";

You can trigger any of the events with a direct call to them, like this:

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

Does that do what you're trying to do?

You should probably also trigger .focus() and potentially .change()

If you want to trigger the key-events with specific keys, you can do so like this:

$(function() {
    var e = $.Event('keypress');
    e.which = 65; // Character 'A'
    $('item').trigger(e);
});

There is some interesting discussion of the keypress events here: jQuery Event Keypress: Which key was pressed?, specifically regarding cross-browser compatability with the .which property.

I know this is not an answer, but I'd like to contribute to this matter for what it's worth. It would be great if they could release justify-self for flexbox to make it truly flexible.

It's my belief that when there are multiple items on the axis, the most logical way for justify-self to behave is to align itself to its nearest neighbours (or edge) as demonstrated below.

I truly hope, W3C takes notice of this and will at least consider it. =)

This way you can have an item that is truly centered regardless of the size of the left and right box. When one of the boxes reaches the point of the center box it will simply push it until there is no more space to distribute.

The ease of making awesome layouts are endless, take a look at this "complex" example.

Some of the other solutions might not work if you created the cookie manually.

Here's a quick way to delete a cookie:

document.cookie = 'COOKIE_NAME=; Max-Age=0; path=/; domain=' + location.host;

You can also use the void operator to obtain an undefined value:

if (input !== void 0) {
    // do stuff    
}

(And yes, as noted in another answer, this will throw an error if the variable was not declared, but this case can often be ruled out either by code inspection, or by code refactoring, e.g. using window.input !== void 0 for testing global variables or adding var input.)

Use map.panTo(); does not do anything if the point is in the current view. Use map.setView() instead.

I had a polyline and I had to center map to a new point in polyline at every second. Check the code : GOOD: https://jsfiddle.net/nstudor/xcmdwfjk/

mymap.setView(point, 11, { animation: true });        

BAD: https://jsfiddle.net/nstudor/Lgahv905/

mymap.panTo(point);
mymap.setZoom(11);

This might be kind of hacky, but it is a good solution if one is bent on accomplishing this using Java 8's java.time:

import java.time.Duration;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.time.format.DateTimeFormatterBuilder;
import java.time.temporal.ChronoField;
import java.time.temporal.Temporal;
import java.time.temporal.TemporalAccessor;
import java.time.temporal.TemporalField;
import java.time.temporal.UnsupportedTemporalTypeException;

public class TemporalDuration implements TemporalAccessor {
    private static final Temporal BASE_TEMPORAL = LocalDateTime.of(0, 1, 1, 0, 0);

    private final Duration duration;
    private final Temporal temporal;

    public TemporalDuration(Duration duration) {
        this.duration = duration;
        this.temporal = duration.addTo(BASE_TEMPORAL);
    }

    @Override
    public boolean isSupported(TemporalField field) {
        if(!temporal.isSupported(field)) return false;
        long value = temporal.getLong(field)-BASE_TEMPORAL.getLong(field);
        return value!=0L;
    }

    @Override
    public long getLong(TemporalField field) {
        if(!isSupported(field)) throw new UnsupportedTemporalTypeException(new StringBuilder().append(field.toString()).toString());
        return temporal.getLong(field)-BASE_TEMPORAL.getLong(field);
    }

    public Duration getDuration() {
        return duration;
    }

    @Override
    public String toString() {
        return dtf.format(this);
    }

    private static final DateTimeFormatter dtf = new DateTimeFormatterBuilder()
            .optionalStart()//second
            .optionalStart()//minute
            .optionalStart()//hour
            .optionalStart()//day
            .optionalStart()//month
            .optionalStart()//year
            .appendValue(ChronoField.YEAR).appendLiteral(" Years ").optionalEnd()
            .appendValue(ChronoField.MONTH_OF_YEAR).appendLiteral(" Months ").optionalEnd()
            .appendValue(ChronoField.DAY_OF_MONTH).appendLiteral(" Days ").optionalEnd()
            .appendValue(ChronoField.HOUR_OF_DAY).appendLiteral(" Hours ").optionalEnd()
            .appendValue(ChronoField.MINUTE_OF_HOUR).appendLiteral(" Minutes ").optionalEnd()
            .appendValue(ChronoField.SECOND_OF_MINUTE).appendLiteral(" Seconds").optionalEnd()
            .toFormatter();

}

You need to do empty_set = set() to initialize an empty set. {} is an empty dict.

Yet another:

#include <stdio.h>
#include <strings.h>

int main(int argc, char **argv) {

  char *reverse = argv[argc-1];
  char *left = reverse;
  int length = strlen(reverse);
  char *right = reverse+length-1;
  char temp;

  while(right-left>=1){

    temp=*left;
    *left=*right;
    *right=temp;
    ++left;
    --right;

  }

  printf("%s\n", reverse);

}

lazy-init is the attribute of bean. The values of lazy-init can be true and false. If lazy-init is true, then that bean will be initialized when a request is made to bean. This bean will not be initialized when the spring container is initialized and if lazy-init is false then the bean will be initialized with the spring container initialization.

I think it's better to avoid the situation. It's cleaner and clearer to write:

a = None
if condition:
    a = 42

I started getting this after upgrading to a new postgres - I didn't realize I had hold data files.

First I tried to start the postgres server:

postgres -D /usr/local/var/postgres

which is how I saw this error

FATAL:  database files are incompatible with server
DETAIL:  The data directory was initialized by PostgreSQL version 9.0, which is not compatible with this version 9.3.5.

So then I found this answer on SO - related to an incompatibility error: https://serverfault.com/questions/342626/how-do-i-upgrade-postgresl-database-incompatibility-error

This is what fixed it

mv /usr/local/var/postgres /usr/local/var/postgres.old
initdb -D /usr/local/var/postgres

Using AddDays(-1) worked for me until I tried to cross months. When I tried to subtract 2 days from 2017-01-01 the result was 2016-00-30. It could not handle the month change correctly (though the year seemed to be fine).

I used date = Convert.ToDateTime(date).Subtract(TimeSpan.FromDays(2)).ToString("yyyy-mm-dd"); and have no issues.

I also wrote a combination of Mockito and AspectJ: https://github.com/iirekm/varia/tree/develop/ajmock

Your example becomes:

when(() -> DriverManager.getConnection(...)).thenReturn(...);

Apache Commons has an IntegerValidator class which appears to do what you want. Java provides no in-built method for doing this.

See here for the groupid/artifactid.

There is a simplest and quick way to import a Gradle project into Eclipse. Just download the Gradle plugin for Eclipse from here.
https://marketplace.eclipse.org/content/gradle-integration-eclipse-0

And then from import select Gradle and your project would be imported. Then you have to click on Build Model to run it.

EDIT
Above link for Gradle plugin is no more valid. You can use the link as mentioned in the comment by @vikramvi

I will suggest something totally different, we used it at work for many years ago on real computers and it worked perfect.

Boot both old and new machine on linux rescue Cd.

read the disk from one, and write it down to the other one, block by block, effectively copying the dist over the network.

You have to play around a little bit with the command line, but it worked so well that both machine complained about IP-conflict when they both booted :-) :-)

cat /dev/sda | ssh user@othermachine cat - > /dev/sda

I got tired of seeing this page with its by-now stale references to defunct Codehaus pages so I asked on the Maven Users mailing list and got some more up-to-date answers.

I would say that the best (and most authoritative) answer contained in my link above is the one contributed by Hervé BOUTEMY:

here is the core reference: http://maven.apache.org/ref/3-LATEST/maven-model-builder/

it does not explain everyting that can be found in POM or in settings, since there are so much info available but it points to POM and settings descriptors and explains everything that is not POM or settings

@Petr Mensik & kensen john

Thanks, I could not used the page directive because I have to set a different content type according to some URL parameter. I will paste my code here since it's something quite common with JSON:

    <%
        String callback = request.getParameter("callback");
        response.setCharacterEncoding("UTF-8");
        if (callback != null) {
            // Equivalent to: <@page contentType="text/javascript" pageEncoding="UTF-8">
            response.setContentType("text/javascript");
        } else {
            // Equivalent to: <@page contentType="application/json" pageEncoding="UTF-8">
            response.setContentType("application/json");
        }

        [...]

        String output = "";

        if (callback != null) {
            output += callback + "(";
        }

        output += jsonObj.toString();

        if (callback != null) {
            output += ");";
        }
    %>
    <%=output %>

When callback is supplied, returns:

    callback({...JSON stuff...});

with content-type "text/javascript"

When callback is NOT supplied, returns:

    {...JSON stuff...}

with content-type "application/json"

I agree with Scheintod that using an existing CSV library is a good idea to have RFC-4180-compliance from the start. Besides the mentioned OpenCSV and Oster Miller, there are a series of other CSV libraries out there. If you're interested in performance, you can take a look at the uniVocity/csv-parsers-comparison. It shows that

• uniVocity CSV parser
• SimpleFlatMapper CSV parser
• Jackson CSV parser

are consistently the fastest using either JDK 6, 7, 8, or 9. The study did not find any RFC 4180 compatibility issues in any of those three. Both OpenCSV and Oster Miller are found to be about twice as slow as those.

I'm not in any way associated with the author(s), but concerning the uniVocity CSV parser, the study might be biased due to its author being the same as of that parser.

To note, the author of SimpleFlatMapper has also published a performance comparison comparing only those three.

No need to reinvent the wheel! Use Currency Mask, unlike TextMaskModule, this one works with number input type and it's super easy to configure. I found when I made my own directive, I had to keep converting between number and string to do calculations. Save yourself the time. Here's the link:

C:\Users\<username>\AppData\Local\GitHub\PortableGit_<random hash>\cmd\git.exe is where my git.exe is located on Windows 10, Git version 2.10.0.0

Edit: With GitHubDesktop, the location changed to this

C:\Users\<username>\AppData\Local\GitHubDesktop\app-1.0.1\resources\app\git\cmd

or the easier way

%USERPROFILE%\AppData\Local\GitHubDesktop\app-1.0.1\resources\app\git\cmd

If you want to avoid closures, and happy to use facades, the following keeps things nice and clean:

try {
    \DB::beginTransaction();

    $user = \Auth::user();
    $user->fill($request->all());
    $user->push();

    \DB::commit();

} catch (Throwable $e) {
    \DB::rollback();
}

If any statements fail, commit will never hit, and the transaction won't process.

If you're dealing with natural language text and need to replace a word, not just part of a string, you have to add a pinch of regular expressions to your gsub as a plain text substitution can lead to disastrous results:

'mislocated cat, vindicating'.gsub('cat', 'dog')
=> "mislodoged dog, vindidoging"

Regular expressions have word boundaries, such as \b which matches start or end of a word. Thus,

'mislocated cat, vindicating'.gsub(/\bcat\b/, 'dog')
=> "mislocated dog, vindicating"

In Ruby, unlike some other languages like Javascript, word boundaries are UTF-8-compatible, so you can use it for languages with non-Latin or extended Latin alphabets:

'???? ? ??????, ??? ??????'.gsub(/\b????\b/, '?????')
=> "????? ? ??????, ??? ??????"

function(e){ e.preventDefault();

and its opposite

function(e){ return true; }

cheers!

For my fellow Swift users, here is the code you will need:

let imageName = "un-child-rights.jpg"
let image = UIImage(named: imageName)
cell.imageView!.image = image

Git uses "the index" to prepare commits. You can add and remove changes from the index before you commit (in your paste you already have deleted ~10 files with git rm). When the index looks like you want it, run git commit.

Usually this will fire up vim. To insert text hit i, <esc> goes back to normal mode, hit ZZ to save and quit (ZQ to quit without saving). voilà, there's your commit

Symbol You Want on Color You Want!

I was looking for this answer for days and here it is the right and easy way to create a custom marker:

'http://chart.googleapis.com/chart?chst=d_map_pin_letter&chld=xxx%7c5680FC%7c000000&.png' where xxx is the text and 5680fc is the hexadecimal color code of the background and 000000 is the hexadecimal color code of the text.

Theses markers are totally dynamic and you can create whatever balloon icon you want. Just change the URL.

The accepted answer is through but there is official explanation on this:

The WebApplicationContext is an extension of the plain ApplicationContext that has some extra features necessary for web applications. It differs from a normal ApplicationContext in that it is capable of resolving themes (see Using themes), and that it knows which Servlet it is associated with (by having a link to the ServletContext). The WebApplicationContext is bound in the ServletContext, and by using static methods on the RequestContextUtils class you can always look up the WebApplicationContext if you need access to it.

Cited from Spring web framework reference

By the way servlet and root context are both webApplicationContext:

this is a programatical approach:

 view.setVisibility(View.GONE); //For GONE
 view.setVisibility(View.INVISIBLE); //For INVISIBLE
 view.setVisibility(View.VISIBLE); //For VISIBLE

public static String[] toArray(String[]... object){
    List<String> list=new ArrayList<>();
    for (String[] i : object) {
        list.addAll(Arrays.asList(i));
    }
    return list.toArray(new String[list.size()]);
}

If you use native sql, you can refer to my code, otherwise just ignore my answer.

SELECT * FROM table WHERE tags LIKE "%banana%";

from sqlalchemy import text

bar_tags = "banana"

# '%' attention to spaces
query_sql = """SELECT * FROM table WHERE tags LIKE '%' :bar_tags '%'"""

# db is sqlalchemy session object
tags_res_list = db.execute(text(query_sql), {"bar_tags": bar_tags}).fetchall()

You can use the crosstab() function of the additional module tablefunc - which you have to install once per database. Since PostgreSQL 9.1 you can use CREATE EXTENSION for that:

CREATE EXTENSION tablefunc;

In your case, I believe it would look something like this:

CREATE TABLE t (Section CHAR(1), Status VARCHAR(10), Count integer);

INSERT INTO t VALUES ('A', 'Active',   1);
INSERT INTO t VALUES ('A', 'Inactive', 2);
INSERT INTO t VALUES ('B', 'Active',   4);
INSERT INTO t VALUES ('B', 'Inactive', 5);

SELECT row_name AS Section,
       category_1::integer AS Active,
       category_2::integer AS Inactive
FROM crosstab('select section::text, status, count::text from t',2)
            AS ct (row_name text, category_1 text, category_2 text);

For the line

line.split()

What are you splitting on? Looks like a CSV, so try

line.split(',')

Example:

"one,two,three".split()  # returns one element ["one,two,three"]
"one,two,three".split(',')  # returns three elements ["one", "two", "three"]

As @TigerhawkT3 mentions, it would be better to use the CSV module. Incredibly quick and easy method available here.

ActionLink will never fire post. It always trigger GET request.

I tried the solution of Oskar (and many others) but for me it finaly only worked with:

jQuery(function($){
   // Your jQuery code here, using the $
});

See: https://learn.jquery.com/using-jquery-core/avoid-conflicts-other-libraries/

Shortest (correct) version:

grep -q "something" file; [ $? -eq 0 ] && echo "yes" || echo "no"

can be also written as

grep -q "something" file; test $? -eq 0 && echo "yes" || echo "no"

but you dont need to explicitly test it in this case, so the same with:

grep -q "something" file && echo "yes" || echo "no"

Your browser may be configured to accept only session cookies; if this is your case, any expiry time is transformed into session by your browser, you can change this setting of your browser or try another browser without such a configuration

Follow following steps:

1. Copy hello.ko to /lib/modules/'uname-r'/misc/
2. Add misc/hello.ko entry in /lib/modules/'uname-r'/modules.dep
3. sudo depmod
4. sudo modprobe hello

modprobe will check modules.dep file for any dependency.

I'm not sure about what you mean by "I have no access to image" But if you have access to parent div you can do the following:

Firs give id or class to your div:

<div class="parent">
   <img src="http://someimage.jpg">
</div>

Than add this to your css:

.parent {
   width: 42px; /* I took the width from your post and placed it in css */
   height: 42px;
}

/* This will style any <img> element in .parent div */
.parent img {
   height: 100%;
   width: 100%;
}

If you want listen an event (i.e OnClick) on an input with "demo" id, you can use:

new Vue({
  el: '#demo',
  data: {
    n: 0
  },
  methods: {
   onClick: function (e) {
     console.log(e.target.tagName) // "A"
     console.log(e.targetVM === this) // true
  }
 }
})

using (StreamWriter w = File.AppendText("myFile.txt"))
{
  w.WriteLine("hello");
}

import curses
stdscr = curses.initscr()
stdscr.clear()

Generic types is a compile time abstraction. At runtime all maps will have the same type Map<Object, Object>. So if you are sure that values are strings, you can cheat on java compiler:

Map<String, Object> m1 = new HashMap<String, Object>();
Map<String, String> m2 = (Map) m1;

Copying keys and values from one collection to another is redundant. But this approach is still not good, because it violates generics type safety. May be you should reconsider your code to avoid such things.

For this gcc error, you should reference to to the gcc document about Search Path.

In short:

1) If you use angle brackets(<>) with #include, gcc will search header file firstly from system path such as /usr/local/include and /usr/include, etc.

2) The path specified by -Ldir command-line option, will be searched before the default directories.

3)If you use quotation("") with #include as #include "file", the directory containing the current file will be searched firstly.

so, the answer to your question is as following:

1) If you want to use header files in your source code folder, replace <> with "" in #include directive.

2) if you want to use -I command line option, add it to your compile command line.(if set CFLAGS in environment variables, It will not referenced automatically)

3) About package configuration(openssl.pc), I do not think it will be referenced without explicitly declared in build configuration.

Wow, this one took me a while to solve, as I was using SVN through Eclipse. In the end, the only thing that worked for me was to commit all non-affected files, then (with Eclipse closed) rename the project directory, and re-check the project out from SVN. Glad it works properly now!

You can use the simple soupparser from lxml

Example:

from lxml.html.soupparser import fromstring

tree = fromstring("<a>Find me!</a>")
print tree.xpath("//a/text()")

Follow the example --

songs = [
{"title": "happy birthday", "playcount": 4},
{"title": "AC/DC", "playcount": 2},
{"title": "Billie Jean", "playcount": 6},
{"title": "Human Touch", "playcount": 3}
]

print("===========================")
print(f'Songs --> {songs} \n')
title = list(map(lambda x : x['title'], songs))
print(f'Print Title --> {title}')

playcount = list(map(lambda x : x['playcount'], songs))
print(f'Print Playcount --> {playcount}')
print (f'Print Sorted playcount --> {sorted(playcount)}')

# Aliter -
print(sorted(list(map(lambda x: x['playcount'],songs))))

I also favor the RegEx solution. The code will be much cleaner. I would hesitate to use toLowerCase() in situations where I knew the strings were going to be large, since strings are immutable and would have to be copied. Also, the matches() solution might be confusing because it takes a regular expression as an argument (searching for "Need$le" cold be problematic).

Building on some of the above examples:

public boolean containsIgnoreCase( String haystack, String needle ) {
  if(needle.equals(""))
    return true;
  if(haystack == null || needle == null || haystack .equals(""))
    return false; 

  Pattern p = Pattern.compile(needle,Pattern.CASE_INSENSITIVE+Pattern.LITERAL);
  Matcher m = p.matcher(haystack);
  return m.find();
}

example call: 

String needle = "Need$le";
String haystack = "This is a haystack that might have a need$le in it.";
if( containsIgnoreCase( haystack, needle) ) {
  System.out.println( "Found " + needle + " within " + haystack + "." );
}

(Note: you might want to handle NULL and empty strings differently depending on your needs. I think they way I have it is closer to the Java spec for strings.)

Speed critical solutions could include iterating through the haystack character by character looking for the first character of the needle. When the first character is matched (case insenstively), begin iterating through the needle character by character, looking for the corresponding character in the haystack and returning "true" if all characters get matched. If a non-matched character is encountered, resume iteration through the haystack at the next character, returning "false" if a position > haystack.length() - needle.length() is reached.

If you have tried all the other answers, and it still hasn't work, you can try skipping a line:

Scanner scan = new Scanner(System.in);
scan.nextLine();
String s = scan.nextLine();
System.out.println("String is " + s);

If you are using WebView in Android developing the problem is that you didn't add uses permission

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

If we look at the implementation of the equalsIgnoreCase method, we find this part:

if (string == null || count != string.count) {
    return false;
}

So it will always return false if the argument is null. And this is obviously right, because the only case where it should return true is when equalsIgnoreCase was invoked on a null String, but

String nullString = null;
nullString.equalsIgnoreCase(null);

will definitely result in a NullPointerException.

So equals methods are not designed to test whether an object is null, just because you can't invoke them on null.

console.log(Math.floor(100000 + Math.random() * 900000));

Will always create a number of 6 digits and it ensures the first digit will never be 0. The code in your question will create a number of less than 6 digits.

Follow the screenshot below. It works when you run the simulator (won't see it on preview)

This is an old question and its been answered but I thought I'd put the --binary-files=text option here for anyone who wants to use it. The -I option ignores the binary file but if you want the grep to treat the binary file as a text file use --binary-files=text like so:

bash$ grep -i reset mediaLog*
Binary file mediaLog_dc1.txt matches
bash$ grep --binary-files=text -i reset mediaLog*
mediaLog_dc1.txt:2016-06-29 15:46:02,470 - Media [uploadChunk  ,315] - ERROR - ('Connection aborted.', error(104, 'Connection reset by peer'))
mediaLog_dc1.txt:ConnectionError: ('Connection aborted.', error(104, 'Connection reset by peer'))
bash$

Or git stash (if you have changes) on the branch you're on, checkout master, pull for the latest changes, grab that file to your desktop (or the entire app). Checkout the branch you were on. Git stash apply back to the state you were at, then fix the changes manually or drag it replacing the file.

This way is not sooooo cool but it def works if you guys can't figure anything else out.

2nd Update: In attempt to provide a comprehensive answer, I am benchmarking the three methods proposed in the various answers.

var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3';
var i;

// Testing the substring method
i = 0;
console.time('10k substring');
while (i < 10000) {
    testURL.substring(0, testURL.indexOf('?'));
    i++;
}
console.timeEnd('10k substring');

// Testing the split method
i = 0;
console.time('10k split');
while (i < 10000) {
    testURL.split('?')[0]; 
    i++;
}
console.timeEnd('10k split');

// Testing the RegEx method
i = 0;
var re = new RegExp("[^?]+");
console.time('10k regex');
while (i < 10000) {
    testURL.match(re)[0]; 
    i++;
}
console.timeEnd('10k regex');

Results in Firefox 3.5.8 on Mac OS X 10.6.2:

10k substring:  16ms
10k split:      25ms
10k regex:      44ms

Results in Chrome 5.0.307.11 on Mac OS X 10.6.2:

10k substring:  14ms
10k split:      20ms
10k regex:      15ms

Note that the substring method is inferior in functionality as it returns a blank string if the URL does not contain a querystring. The other two methods would return the full URL, as expected. However it is interesting to note that the substring method is the fastest, especially in Firefox.

1st UPDATE: Actually the split() method suggested by Robusto is a better solution that the one I suggested earlier, since it will work even when there is no querystring:

var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3';
testURL.split('?')[0];    // Returns: "/Products/List"

var testURL2 = '/Products/List';
testURL2.split('?')[0];    // Returns: "/Products/List"

Original Answer:

var testURL = '/Products/List?SortDirection=dsc&Sort=price&Page=3&Page2=3';
testURL.substring(0, testURL.indexOf('?'));    // Returns: "/Products/List"

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

Instead of using a Label use a text input:

<script type="text/javascript">
    onChange = function(ctrl) {
        var txt = document.getElementById("<%= txtResult.ClientID %>");
        if (txt){
            txt.value = ctrl.value;
        }           
    }
</script>

<asp:TextBox ID="txtTest" runat="server" onchange="onChange(this);" />      

<!-- pseudo label that will survive postback -->  
<input type="text" id="txtResult" runat="server" readonly="readonly" tabindex="-1000" style="border:0px;background-color:transparent;" />        

<asp:Button ID="btnTest" runat="server" Text="Test" />

Using the selectedOptions property:

var yourSelect = document.getElementById("your-select-id");
alert(yourSelect.selectedOptions[0].value);

It works in all browsers except Internet Explorer.

You can use the pointer-events property in your CSS, and set it equal to 'none'

img {
    pointer-events: none;
}

Edited

this will block (click) event. So better solution would be

<img draggable="false" (dragstart)="false;" class="unselectable">

.unselectable {
  user-drag: none; 
  user-select: none;
  -moz-user-select: none;
  -webkit-user-drag: none;
  -webkit-user-select: none;
  -ms-user-select: none;
}

No longer works for spreadsheets Protected with Excel 2013 or later -- they improved the pw hash. So now need to unzip .xlsx and hack the internals.

An easy way to calculate MODE of a vector 'v' containing discrete values is:

names(sort(table(v)))[length(sort(table(v)))]

From info gcc (emphasis mine):

-ansi

In C mode, this is equivalent to -std=c90. In C++ mode, it is equivalent to -std=c++98. This turns off certain features of GCC that are incompatible with ISO C90 (when compiling C code), or of standard C++ (when compiling C++ code), such as the asm and typeof keywords, and predefined macros such as 'unix' and 'vax' that identify the type of system you are using. It also enables the undesirable and rarely used ISO trigraph feature. For the C compiler, it disables recognition of C++ style // comments as well as the inline keyword.

(It uses vax in the example instead of linux because when it was written maybe it was more popular ;-).

The basic idea is that GCC only tries to fully comply with the ISO standards when it is invoked with the -ansi option.

For me

grep -b "searchsomething" *.log

worked as I wanted

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

Setting locales in terminal resolved the issue for me. Open the terminal and

1. Check if locale settings are missing

   > locale
   LANG=
   LC_COLLATE="C"
   LC_CTYPE="UTF-8"
   LC_MESSAGES="C"
   LC_MONETARY="C"
   LC_NUMERIC="C"
   LC_TIME="C"
   LC_ALL=
   

2. Edit ~/.profile or ~/.bashrc

   export LANG=en_US.UTF-8
   export LC_ALL=en_US.UTF-8
   

3. Run . ~/.profile or . ~/.bashrc to read from the file.

4. Open a new terminal window and check that the locales are properly set

   > locale
   LANG="en_US.UTF-8"
   LC_COLLATE="en_US.UTF-8"
   LC_CTYPE="en_US.UTF-8"
   LC_MESSAGES="en_US.UTF-8"
   LC_MONETARY="en_US.UTF-8"
   LC_NUMERIC="en_US.UTF-8"
   LC_TIME="en_US.UTF-8"
   LC_ALL="en_US.UTF-8"
   

What operating system are you using? I use Linux Mint. In my case it turned out to be a symbolic link issue. Every time I tried to create the project with the symlink path, it would give me that error. Creating the project elsewhere, and then migrating it to the symlinked directory solved it for me.

public demo1() {
    initComponents();
    ImageIcon img = new ImageIcon("C:\\Users\\AMIT TIWARI\\Documents\\NetBeansProjects\\try\\src\\com\\dd.jpeg"); //full path of image
    Image img2 = img.getImage().getScaledInstance(mylabel.getWidth(), mylabel.getHeight(),1);
    ImageIcon img3 = new ImageIcon(img2);
    mylabel.setIcon(img3);
}

This is to help others completely new to react and who area having problems just starting a first app even though they did a fresh install and try using npm install and the other fixes I saw around the forums.

Running it on Windows 10 with all the latest npm create-react-app installed and got failure after failure on a simple npm start in a simple my-app demo folder.

Spent a long time with what looks similar to the OP error at first but is slightly different. This starts with ERRNO 4058 and continues with code 'ENOENT' syscall: 'spawn cmd', path: ''cmd' ...

Eventually worked out from github create-react-app forum that a quick fix for this is registering cmd in the "path" variable. To do this go to System Properties>Environment variables. Click on path variable edit and and add new entry of C:\Windows\System32. Restart CMD prompt and I was good to go.

In the situation where you are NOT going to use this over and over (i.e. not needed in your style sheet), inline style statements usually work anywhere they would work inyour style sheet. E.g:

<div data-role="controlgroup" data-type="horizontal" style="text-align:center;">

As I understand the question, it it more about downloading just certain state from the server, without history, and without data of other branches, rather than extracting a state from a local repository (as many anwsers here do).

That can be done like this:

git clone -b someBranch --depth 1 --single-branch git://somewhere.com/repo.git \
&& rm -rf repo/.git/

• --single-branch is available since Git 1.7.10 (April 2012).
• --depth is (was?) reportedly faulty, but for the case of an export, the mentioned issues should not matter.

Update (as 2019):

cd ~/.vim
git clone git://github.com/tpope/vim-haml.git pack/bundle/start/haml

Explanation (from :h pack ad :h packages):

1. All the directories found are added to runtimepath. They must be in ~/.vim/pack/whatever/start [you can only change whatever].
2. the plugins found in the plugins dir in runtimepath are sourced.

So this load the plugin on start (hence the name start).

You can also get optional plugin (loaded with :packadd) if you put them in ~/.vim/pack/bundle/opt

You need to enclose that in <%! %> as follows:

<%!

public String getQuarter(int i){
String quarter;
switch(i){
        case 1: quarter = "Winter";
        break;

        case 2: quarter = "Spring";
        break;

        case 3: quarter = "Summer I";
        break;

        case 4: quarter = "Summer II";
        break;

        case 5: quarter = "Fall";
        break;

        default: quarter = "ERROR";
}

return quarter;
}

%>

You can then invoke the function within scriptlets or expressions:

<%
     out.print(getQuarter(4));
%>

or

<%= getQuarter(17) %>

Using -webkit-appearance:none; will remove also the arrows indicating that this is a dropdown.

See this snippet that makes it work across different browsers an adds custom arrows without including any image files:

you can't force refresh but you can forward all old ip requests to new one. for a website:

replace [OLD_IP] with old server's ip

replace [NEW_IP] with new server's ip

run & win.

echo "1" > /proc/sys/net/ipv4/ip_forward

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 80 -j DNAT --to-destination [NEW_IP]:80

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 443 -j DNAT --to-destination [NEW_IP]:443

iptables -t nat -A POSTROUTING -j MASQUERADE

You can use the following to capitalize words in a string:

function capitalizeAll(str){

    var partes = str.split(' ');

    var nuevoStr = ""; 

    for(i=0; i<partes.length; i++){
    nuevoStr += " "+partes[i].toLowerCase().replace(/\b\w/g, l => l.toUpperCase()).trim(); 
    }    

    return nuevoStr;

}

How to execute an SQL script, use this syntax:

mysql --host= localhost --user=root --password=xxxxxx  -e "source dbscript.sql"

If you use host as localhost you don't need to mention it. You can use this:

mysql --user=root --password=xxxxxx  -e "source dbscript.sql"

This should work for Windows and Linux.

If the password content contains a ! (Exclamation mark) you should add a \ (backslash) in front of it.
