I've had the same problem, what I did:

Just added a condition if(!IsPostBack) and it works fine :)

I had the same problem and apparently is solved now, despite this and some other gdi+ exceptions are very misleading, I found that actually the problem was that the parameter being sent to a Bitmap constructor was not valid. I have this code:

using (System.IO.FileStream fs = new System.IO.FileStream(inputImage, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite))
{
    try
    {
        using (Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false))
        {
            try
            {
                bitmap.Save(OutputImage + ".bmp", System.Drawing.Imaging.ImageFormat.Bmp);
                GC.Collect();
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
    }
    catch (ArgumentException aex)
    {
        throw new Exception("The file received from the Map Server is not a valid jpeg image", aex);
    }
}

The following line was causing an error:

Bitmap bitmap = (Bitmap)Image.FromStream(fs, true, false)

The file stream was built from the file downloaded from the Map Server. My app was sending the request incorrectly to get the image, and the server was returning something with the jpg extension, but was actually a html telling me that an error ocurred. So I was taking that image and trying to build a Bitmap with it. The fix was to control/ validate the image for a valid jpeg image.

Hope it helps!

My understanding is that this is actually very simple:

• Javascript is always pass by value, but when a variable refers to an object (including arrays), the "value" is a reference to the object.
• Changing the value of a variable never changes the underlying primitive or object, it just points the variable to a new primitive or object.
• However, changing a property of an object referenced by a variable does change the underlying object.

So, to work through some of your examples:

function f(a,b,c) {
    // Argument a is re-assigned to a new value.
    // The object or primitive referenced by the original a is unchanged.
    a = 3;
    // Calling b.push changes its properties - it adds
    // a new property b[b.length] with the value "foo".
    // So the object referenced by b has been changed.
    b.push("foo");
    // The "first" property of argument c has been changed.
    // So the object referenced by c has been changed (unless c is a primitive)
    c.first = false;
}

var x = 4;
var y = ["eeny", "miny", "mo"];
var z = {first: true};
f(x,y,z);
console.log(x, y, z.first); // 4, ["eeny", "miny", "mo", "foo"], false

Example 2:

var a = ["1", "2", {foo:"bar"}];
var b = a[1]; // b is now "2";
var c = a[2]; // c now references {foo:"bar"}
a[1] = "4";   // a is now ["1", "4", {foo:"bar"}]; b still has the value
              // it had at the time of assignment
a[2] = "5";   // a is now ["1", "4", "5"]; c still has the value
              // it had at the time of assignment, i.e. a reference to
              // the object {foo:"bar"}
console.log(b, c.foo); // "2" "bar"

find location -ctime time_period

Examples of time_period:

• More than 30 days ago: -ctime +30

• Less than 30 days ago: -ctime -30

• Exactly 30 days ago: -ctime 30

The answer from Daniel works just perfect. Here is a sample snippet that I added to my build.xml:

<target name="compile">
    <mkdir dir="${classes.dir}"/>
    <javac srcdir="${src.dir}" destdir="${classes.dir}" includeantruntime="false">
                                                 <!--   ^^^^^^^^^^^^^^^^^^^^^^^^^  -->
        <classpath>
            <path id="application" location="${jar.dir}/${ant.project.name}.jar"/>
            <path id="junit" location="${lib.dir}/junit-4.9b2.jar"/>
        </classpath>
    </javac>
</target>

this simple script worked for me.

<?php

foreach($_FILES as $file){
  //echo $file['name']; 
  echo $file['tmp_name'].'</br>'; 
  move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}

?>

Using #!/usr/bin/env NAME makes the shell search for the first match of NAME in the $PATH environment variable. It can be useful if you aren't aware of the absolute path or don't want to search for it.

It's easier for me to think in these terms, but borrowing from other answers. The value you want is located in the series:

df[*column*][*row*]

where column and row point to the value you want returned. For your example, column is 'A' and for row you use a mask:

df['B'] == 3

To get the value from the series there are several options:

df['A'][df['B'] == 3].values[0]
df['A'][df['B'] == 3].iloc[0]
df['A'][df['B'] == 3].to_numpy()[0]

It's possible that the HTML5 Doctype is causing you problems with those older browsers. It could also be down to something funky related to the HTML5 shiv.

You could try switching to one of the XHTML doctypes and changing your markup accordingly, at least temporarily. This might allow you to narrow the problem down.

Is your design breaking when those IEs switch to quirks mode? If it's your CSS causing things to display strangely, it might be worth working on the CSS so the site looks the same even when the browsers switch modes.

How about: "$env:computername.$env:userdnsdomain"

This actually only works if the user is logged into a domain (i.e. no local accounts), logged into the same domain as the server, and doesn't work with disjointed name space AD configurations.

Use this as referenced in another answer:

$myFQDN=(Get-WmiObject win32_computersystem).DNSHostName+"."+(Get-WmiObject win32_computersystem).Domain ; Write-Host $myFQDN

Here is my way. I try to group data fist.

const _ = require("underscore")

var test  = [ 1, 1, 2, 1 ];
var groupResult = _.groupBy(test, (e)=> e);

The groupResult should be

{
  1: [1, 1, 1]
  2: [2] 
}

Then find the property which has the longest array

function findMax(groupResult){
   var maxArr = []
   var max;
   for(var item in groupResult){
     if(!max) { 
        max = { value:item, count: groupResult[item].length } ; 
        maxArr.push(max); 
        continue;
     }
     if(max.count < groupResult[item].length){ 
        maxArr = [];
        max = { value:item, count: groupResult[item].length }
        maxArr.push(max)
     } else if(max === groupResult[item].length)
        maxArr.push({ value:item, count: groupResult[item].length })
   }
   return maxArr;
}

The complete code looks like

const _ = require("underscore")

var test  = [ 1, 1, 2, 1 ];
var groupResult= _.groupBy(test, (e)=> e);
console.log(findMax(groupResult)[0].value);

function findMax(groupResult){
   var maxArr = []
   var max;
   for(var item in groupResult){
     if(!max) { 
        max = { value:item, count: groupResult[item].length } ; 
        maxArr.push(max); 
        continue;
     }
     if(max.count < groupResult[item].length){ 
        maxArr = [];
        max = { value:item, count: groupResult[item].length }
        maxArr.push(max)
     } else if(max === groupResult[item].length)
        maxArr.push({ value:item, count: groupResult[item].length })
   }
   return maxArr;
}

const regex = new RegExp(`ReGeX${testVar}ReGeX`);
...
string.replace(regex, "replacement");

Update

Per some of the comments, it's important to note that you may want to escape the variable if there is potential for malicious content (e.g. the variable comes from user input)

ES6 Update

In 2019, this would usually be written using a template string, and the above code has been updated. The original answer was:

var regex = new RegExp("ReGeX" + testVar + "ReGeX");
...
string.replace(regex, "replacement");

    <script type="text/javascript">
<!-- 
function newPage(num) {
var url=new Array();
url[0]="http://www.htmlforums.com";
url[1]="http://www.codingforums.com.";
url[2]="http://www.w3schools.com";
url[3]="http://www.webmasterworld.com";
window.location=url[num];``
}
// -->
</script>
</head>
<body>
<form action="#">
<div id="container">
<input class="butts" type="button" value="htmlforums" onclick="newPage(0)"/>
<input class="butts" type="button" value="codingforums" onclick="newPage(1)"/>
<input class="butts" type="button" value="w3schools" onclick="newPage(2)"/>
<input class="butts" type="button" value="webmasterworld" onclick="newPage(3)"/>
</div>
</form>
</body>

Here's the other way, it's simpler than the other one.

<input id="inp" type="button" value="Home Page" onclick="location.href='AdminPage.jsp';" />

It's simpler.

You should use > or < and == here. So the solution would be:

list.sort(function(item1, item2) {
    var val1 = item1.attr,
        val2 = item2.attr;
    if (val1 == val2) return 0;
    if (val1 > val2) return 1;
    if (val1 < val2) return -1;
});

You can fix it by replacing the function .text() to .html(). its working for me.

I would suggest separating your code based on the functionality and purpose specific to each sheet or module. In this manner, you would only put code relative to a sheet's UI inside the sheet's module and only put code related to modules in respective modules. Also, use separate modules to encapsulate code that is shared or reused among several different sheets.

For example, let's say you multiple sheets that are responsible for displaying data from a database in a special way. What kinds of functionality do we have in this situation? We have functionality related to each specific sheet, tasks related to getting data from the database, and tasks related to populating a sheet with data. In this case, I might start with a module for the data access, a module for populating a sheet with data, and within each sheet I'd have code for accessing code in those modules.

It might be laid out like this.

Module: DataAccess:

Function GetData(strTableName As String, strCondition1 As String) As Recordset
    'Code Related to getting data from the database'
End Function

Module: PopulateSheet:

Sub PopulateASheet(wsSheet As Worksheet, rs As Recordset)
    'Code to populate a worksheet '
End Function

Sheet: Sheet1 Code:

Sub GetDataAndPopulate()
    'Sample Code'
     Dim rs As New Recordset
     Dim ws As Worksheet
     Dim strParam As String
     Set ws = ActiveSheet
     strParam = ws.Range("A1").Value

     Set rs = GetData("Orders",strParam)

     PopulateASheet ws, rs
End Sub

Sub Button1_Click()
    Call GetDataAndPopulate
End Sub

It just means that the server cannot find your image.

Remember The image path must be relative to the CSS file location

Check the path and if the image file exist.

If you specify ZEROFILL for a numeric column, MySQL automatically adds the UNSIGNED attribute to the column.

Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.

Above description is taken from MYSQL official website.

I believe however if you combine all of your statements and run it in Java 8.1 you will get a different answer, at least that's what my experience says.

The code will work like this:

int a=5,i;

i=++a + ++a + a++;            /*a = 5;
                                i=++a + ++a + a++; =>
                                i=6 + 7 + 7; (a=8); i=20;*/

i=a++ + ++a + ++a;           /*a = 5;
                                i=a++ + ++a + ++a; =>
                                i=8 + 10 + 11; (a=11); i=29;*/

a=++a + ++a + a++;            /*a=5;
                                a=++a + ++a + a++; =>
                                a=12 + 13 + 13;  a=38;*/

System.out.println(a);        //output: 38
System.out.println(i);         //output: 29

As other have mentioned you can't display an image in an alert. The solution is to show it on the webpage.

If I have my webpage paused in the debugger and I already have an image loaded, I can display it. There is no need to use jQuery; with this native 14 lines of Javascript it will work from code or the debugger command line:

function show(img){
 var _=document.getElementById('_'); 
 if(!_){_=document.createElement('canvas');document.body.appendChild(_);}
 _.id='_';
 _.style.top=0;
 _.style.left=0;
 _.width=img.width;
 _.height=img.height;
 _.style.zIndex=9999; 
 _.style.position='absolute';
 _.getContext('2d').drawImage(img,0,0);
}

Usage:

show( myimage );

The 'accepted' answer is wrong (as some comments below point out). this modification can make it work:

if (data.toString() === parseInt(data, 10).toString())
    alert("data is a valid integer")
else
    alert("data is not a valid integer")

If your segue exists in the storyboard with a segue identifier between your two views, you can just call it programmatically using

self.performSegueWithIdentifier("yourIdentifierInStoryboard", sender: self)

If you are in Navigation controller

let viewController = YourViewController(nibName: "YourViewController", bundle: nil)        
self.navigationController?.pushViewController(viewController, animated: true)

I will recommend you for second approach using navigation controller.

As others have already said, type hinting currently only works for object types. But I think the particular error you've triggered might be in preparation of the upcoming string type SplString.

In theory it behaves like a string, but since it is an object would pass the object type verification. Unfortunately it's not yet in PHP 5.3, might come in 5.4, so haven't tested this.

I don't have enough rep to answer ClintEastwood, and the accepted answer is correct for the Web.config file. Adding this in for code difference.

When your mailSettings are set on Web.config, you don't need to do anything other than new up your SmtpClient and .Send. It finds the connection itself without needing to be referenced. You would change your C# from this:

SmtpClient smtpClient = new SmtpClient("smtp.sender.you", Convert.ToInt32(587));
System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("username", "password");
smtpClient.Credentials = credentials;
smtpClient.Send(msgMail);  

To this:

SmtpClient smtpClient = new SmtpClient();
smtpClient.Send(msgMail);

Oh! just read comments in question, dear I missed it. but just letting the answer be here in case it can be useful to some other person

I tried "Ctrl+C" and "Ctrl+ Break" none worked. I was using SQL Plus that came with Oracle Client 10.2.0.1.0. SQL Plus is used by most as client for connecting with Oracle DB. I used the Cancel, option under File menu and it stopped the execution!

Once you click File wait for few mins then the select command halts and menu appears click on Cancel.

I was trying to use all the advices above, but unfortunately no one helped me. So finally I've decided to delete my intelij workspace and create the new one - it helped :) But earlier I was also doing cleaning the cache, reimporting maven projects, cleaning projects and rebuilding them.

This will give you the full name of the month.

select datename(month, S0.OrderDateTime)

If you only want the first three letters you can use this

select convert(char(3), S0.OrderDateTime, 0)

<location path="ControllerName/ActionName">
    <system.web>
        <httpRuntime executionTimeout="1000"/>
    </system.web>
</location>

Probably it is better to set such values in web.config instead of controller. Hardcoding of configurable options is considered harmful.

You can do it pretty fast without creating extra arrays, so this will work even for very large arrays:

dict(izip(*([iter(a)]*2)))

If you have a generator a, even better:

dict(izip(*([a]*2)))

Here's the rundown:

iter(h)    #create an iterator from the array, no copies here
[]*2       #creates an array with two copies of the same iterator, the trick
izip(*())  #consumes the two iterators creating a tuple
dict()     #puts the tuples into key,value of the dictionary

To create these constraints through the GUI you need the "indexes and keys" dialogue not the check constraints one.

But in your case you just need to run the piece of code you already have. It doesn't need to be entered into the expression dialogue at all.

The short answer to 2nd part of the question is simply that CString class doesn't provide a direct typecast conversion by design and what you are doing is kind of cheat.

A longer answer is the following:

The reason you can typcast CString to LPCTSTR is because CString provides this facility by overriding operator=. By design it provides conversion to only LPCTSTR pointer so the string value can't be modified with this pointer.

In other words, it simply doesn't provide an overload operator= to convert the CString into LPSTR for the same reason as above. They don't want to allow altering the string value this way.

So essentially, the trick is to use the operator CString provide and get this:

LPTSTR lptstr = (LPCTSTR) string; // CString provide this operator overload

Now LPTSTR can be further type casted to LPSTR :)

dispinfo.item.pszText = LPTSTR( lpfzfd); // accomplish the cheat :P

The correct way to get LPTSTR from 'CString' is this though (complete example):

CString str = _T("Hello");
LPTSTR lpstr = str.GetBuffer(str.GetAllocLength());
str.ReleaseBuffer(); // you must call this function if you change the string above with the pointer

Again because the GetBuffer() returns LPTSTR for that reason that now you can modify :)

If you want it to work in browsers that don't support history.pushState and history.popState yet, the "old" way is to set the fragment identifier, which won't cause a page reload.

The basic idea is to set the window.location.hash property to a value that contains whatever state information you need, then either use the window.onhashchange event, or for older browsers that don't support onhashchange (IE < 8, Firefox < 3.6), periodically check to see if the hash has changed (using setInterval for example) and update the page. You will also need to check the hash value on page load to set up the initial content.

If you're using jQuery there's a hashchange plugin that will use whichever method the browser supports. I'm sure there are plugins for other libraries as well.

One thing to be careful of is colliding with ids on the page, because the browser will scroll to any element with a matching id.

Instead of putting it on top of the file (or even a header file), just wrap the code in question with #pragma warning (push), #pragma warning (disable) and a matching #pragma warning (pop), as shown here.

Although there are some other options, including #pramga warning (once).

In Ubuntu, from MySQL monitor, you have already used this syntax:

mysql> use <dbname> -> The USE statement tells MySQL to use dbname as the default database for subsequent statements

mysql> source <file-path>

for example:

mysql> use phonebook;

mysql> source /tmp/phonebook.sql;

Important: make sure the sql file is in a directory that mysql can access to like /tmp

You can also use the clock_gettime. This method can be used to measure:

1. System wide real-time clock
2. System wide monotonic clock
3. Per Process CPU time
4. Per process Thread CPU time

Code is as follows:

#include < time.h >
#include <iostream>
int main(){
  timespec ts_beg, ts_end;
  clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &ts_beg);
  clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &ts_end);
  std::cout << (ts_end.tv_sec - ts_beg.tv_sec) + (ts_end.tv_nsec - ts_beg.tv_nsec) / 1e9 << " sec";
}

`

The common approach would be to check it with a regular expression like it's also suggested inside the Double.valueOf(String) documentation.

The regexp provided there (or included below) should cover all valid floating point cases, so you don't need to fiddle with it, since you will eventually miss out on some of the finer points.

If you don't want to do that, try catch is still an option.

The regexp suggested by the JavaDoc is included below:

final String Digits     = "(\\p{Digit}+)";
final String HexDigits  = "(\\p{XDigit}+)";
// an exponent is 'e' or 'E' followed by an optionally 
// signed decimal integer.
final String Exp        = "[eE][+-]?"+Digits;
final String fpRegex    =
    ("[\\x00-\\x20]*"+ // Optional leading "whitespace"
    "[+-]?(" +         // Optional sign character
    "NaN|" +           // "NaN" string
    "Infinity|" +      // "Infinity" string

    // A decimal floating-point string representing a finite positive
    // number without a leading sign has at most five basic pieces:
    // Digits . Digits ExponentPart FloatTypeSuffix
    // 
    // Since this method allows integer-only strings as input
    // in addition to strings of floating-point literals, the
    // two sub-patterns below are simplifications of the grammar
    // productions from the Java Language Specification, 2nd 
    // edition, section 3.10.2.

    // Digits ._opt Digits_opt ExponentPart_opt FloatTypeSuffix_opt
    "((("+Digits+"(\\.)?("+Digits+"?)("+Exp+")?)|"+

    // . Digits ExponentPart_opt FloatTypeSuffix_opt
    "(\\.("+Digits+")("+Exp+")?)|"+

    // Hexadecimal strings
    "((" +
    // 0[xX] HexDigits ._opt BinaryExponent FloatTypeSuffix_opt
    "(0[xX]" + HexDigits + "(\\.)?)|" +

    // 0[xX] HexDigits_opt . HexDigits BinaryExponent FloatTypeSuffix_opt
    "(0[xX]" + HexDigits + "?(\\.)" + HexDigits + ")" +

    ")[pP][+-]?" + Digits + "))" +
    "[fFdD]?))" +
    "[\\x00-\\x20]*");// Optional trailing "whitespace"

if (Pattern.matches(fpRegex, myString)){
    Double.valueOf(myString); // Will not throw NumberFormatException
} else {
    // Perform suitable alternative action
}

application/force-download is not a standard MIME type. It's a hack supported by some browsers, added fairly recently.

Your question doesn't really make any sense. It's like asking why Internet Explorer 4 doesn't support the latest CSS 3 functionality.

Yes, you can use find_elements_by_ to retrieve children elements into a list. See the python bindings here: http://selenium-python.readthedocs.io/locating-elements.html

<ul class="bar">
    <li>one</li>
    <li>two</li>
    <li>three</li>
</ul>

You can use the find_elements_by_ like so:

parentElement = driver.find_element_by_class_name("bar")
elementList = parentElement.find_elements_by_tag_name("li")

If you want help with a specific case, you can edit your post with the HTML you're looking to get parent and children elements from.

It looks to me as though the basic problem is that you have one wait() call rather than a loop that waits until there are no more children. You also only wait if the last fork() is successful rather than if at least one fork() is successful.

You should only use _exit() if you don't want normal cleanup operations - such as flushing open file streams including stdout. There are occasions to use _exit(); this is not one of them. (In this example, you could also, of course, simply have the children return instead of calling exit() directly because returning from main() is equivalent to exiting with the returned status. However, most often you would be doing the forking and so on in a function other than main(), and then exit() is often appropriate.)

Hacked, simplified version of your code that gives the diagnostics I'd want. Note that your for loop skipped the first element of the array (mine doesn't).

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main(void)
{
    pid_t child_pid, wpid;
    int status = 0;
    int i;
    int a[3] = {1, 2, 1};

    printf("parent_pid = %d\n", getpid());
    for (i = 0; i < 3; i++)
    {
        printf("i = %d\n", i);
        if ((child_pid = fork()) == 0)
        {
            printf("In child process (pid = %d)\n", getpid());
            if (a[i] < 2)
            {
                printf("Should be accept\n");
                exit(1);
            }
            else
            {
                printf("Should be reject\n");
                exit(0);
            }
            /*NOTREACHED*/
        }
    }

    while ((wpid = wait(&status)) > 0)
    {
        printf("Exit status of %d was %d (%s)\n", (int)wpid, status,
               (status > 0) ? "accept" : "reject");
    }
    return 0;
}

Example output (MacOS X 10.6.3):

parent_pid = 15820
i = 0
i = 1
In child process (pid = 15821)
Should be accept
i = 2
In child process (pid = 15822)
Should be reject
In child process (pid = 15823)
Should be accept
Exit status of 15823 was 256 (accept)
Exit status of 15822 was 0 (reject)
Exit status of 15821 was 256 (accept)

random.choice([True, False])

would also work.

For more information about .scrollHeight property refer to the docs:

The Element.scrollHeight read-only attribute is a measurement of the height of an element's content, including content not visible on the screen due to overflow. The scrollHeight value is equal to the minimum clientHeight the element would require in order to fit all the content in the viewpoint without using a vertical scrollbar. It includes the element padding but not its margin.

While generating the links set the target to the iframes name property and you probably wont have to deal with jquery at all.

<a href="inventory.aspx" target="contentframe"  title="Title Inventory">
<iframe id="iframe1" name="contentframe"  ></iframe>

Clone the repository as normal:

git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle

Then checkout the tag you want like so:

git checkout tags/1.1.4

This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".

To retain any changes made, move them to a new branch:

git checkout -b 1.1.4-jspooner

You can get back to the master branch by using:

git checkout master

Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:

git checkout 1.1.4

But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:

warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'

The shorthand can be safely used if the repository does not share names between branches and tags.

I just solved this exact problem for myself.

The problem was that somebody else had created the file so even though I have admin rights on the computer I was unable to make changes to the file or files. You need to go into the properties of the file or folder and change the ownership or add ownership. This web page explains it well step by step what you need to do.

Once I did the above, I found the file in file explorer and manually extracted it. I don't think it's needed in the android studio project if it was trying to delete it anyway.

A hashtable is the traditional implementation of a simple "Dictionary". If you don't care about speed or size, just google for it. There are many freely available implementations.

here's the first one I saw -- at a glance, it looks ok to me. (it's pretty basic. If you really want it to hold an unlimited amount of data, then you'll need to add some logic to "realloc" the table memory as it grows.)

good luck!

Try using Response.SetCookie(), because Response.Cookies.Add() can cause multiple cookies to be added, whereas SetCookie will update an existing cookie.

Use String.Format() with multiple parameters.

using System;

namespace TimeSpanFormat
{
    class Program
    {
        static void Main(string[] args)
        {
            TimeSpan dateDifference = new TimeSpan(0, 0, 6, 32, 445);
            string formattedTimeSpan = string.Format("{0:D2} hrs, {1:D2} mins, {2:D2} secs", dateDifference.Hours, dateDifference.Minutes, dateDifference.Seconds);
            Console.WriteLine(formattedTimeSpan);
        }
    }
}

I would advise reading Java puzzlers. It explains inheritance, generics, abstractions, and wildcards in declarations quite well. http://www.javapuzzlers.com/

For anyone looking also for a solution for authentication, I would add on the scoped packages solution that you can have multiple lines in your .npmrc file:

//internal-npm.example.com:8080/:_authToken=xxxxxxxxxxxxxxx
//registry.npmjs.org/:_authToken=yyyyyyyyyy

Each line represents a different NPM registry

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

A Serial field was added to the Build class in API level 9 (Android 2.3 - Gingerbread). Documentation says it represents the hardware serial number. Thus it should be unique, if it exists on the device.

I don't know whether it is actually supported (=not null) by all devices with API level >= 9 though.

According to the Python 2.7.2 documentation:

An object is hashable if it has a hash value which never changes during its lifetime (it needs a hash() method), and can be compared to other objects (it needs an eq() or cmp() method). Hashable objects which compare equal must have the same hash value.

Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.

All of Python’s immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id().

A tuple is immutable in the sense that you cannot add, remove or replace its elements, but the elements themselves may be mutable. List's hash value depends on the hash values of its elements, and so it changes when you change the elements.

Using id's for list hashes would imply that all lists compare differently, which would be surprising and inconvenient.

git rm --cached file will remove the file from the stage. That is, when you commit the file will be removed. git reset HEAD -- file will simply reset file in the staging area to the state where it was on the HEAD commit, i.e. will undo any changes you did to it since last commiting. If that change happens to be newly adding the file, then they will be equivalent.

Create a .bat file and write two commands:

cd C:\ Path to your tomcat directory \ bin

startup.bat

Now on double-click, Tomcat server will start.

Optional should mainly be used for results of Services anyway. In the service you know what you have at hand and return Optional.of(someValue) if you have a result and return Optional.empty() if you don't. In this case, someValue should never be null and still, you return an Optional.

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

Your code works for me on Chrome (5.0.375), and Safari (5.0). Doesn't loop on Firefox (3.6).

See example.

var song = new Audio("file");
song.loop = true;
document.body.appendChild(song);?

Your syntax is slightly wrong. Say:

*/15 * * * * command
  |
  |--> `*/15` would imply every 15 minutes.

* indicates that the cron expression matches for all values of the field.

/ describes increments of ranges.

Dim regDate As Date = Date.Now.date

This should fix your problem, though it's 2 years old!

I use the following formula that extends previous answers:

class A(object):
 def __init__(self):
   print "world"

class B(A):
 def __init__(self):
   print "hello"
   super(self.__class__, self).__init__()

B()

This way you don't have to repeat the name of the class in the call to super. It can come handy if you are coding a large number of classes, and want to make your code in the initialiser methods independent of the class name.

<iframe src="page.html"></iframe>

You will need to add some styling to this iframe. You can specify width, height, and if you want it to look like a part of the original page include frameborder="0".

There is no other way to do it in pure HTML. This is what they were built for, it's like saying I want to fry an egg without an egg.

I had the same issue when updating to MVC 5 and it was solved by updating the web.config inside the Views folder.

<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
  <namespaces>
    <add namespace="System.Web.Mvc" />
    <add namespace="System.Web.Mvc.Ajax" />
    <add namespace="System.Web.Mvc.Html" />
    <add namespace="System.Web.Optimization"/>
    <add namespace="System.Web.Routing" />
  </namespaces>
</pages>

The host -> factoryType was set to version:4.0.0.0 hope this helps anyone.

The reason that you get the 404 File Not Found error, is that your path to CSS given as a value to the href attribute is missing context path.

An HTTP request URL contains the following parts:

http://[host]:[port][request-path]?[query-string]

The request path is further composed of the following elements:

• Context path: A concatenation of a forward slash (/) with the context root of the servlet's web application. Example: http://host[:port]/context-root[/url-pattern]

• Servlet path: The path section that corresponds to the component alias that activated this request. This path starts with a forward slash (/).

• Path info: The part of the request path that is not part of the context path or the servlet path.

Read more here.

Solutions

There are several solutions to your problem, here are some of them:

1) Using <c:url> tag from JSTL

In my Java web applications I usually used <c:url> tag from JSTL when defining the path to CSS/JavaScript/image and other static resources. By doing so you can be sure that those resources are referenced always relative to the application context (context path).

If you say, that your CSS is located inside WebContent folder, then this should work:

<link type="text/css" rel="stylesheet" href="<c:url value="/globalCSS.css" />" />

The reason why it works is explained in the "JavaServer Pages™ Standard Tag Library" version 1.2 specification chapter 7.5 (emphasis mine):

7.5 <c:url>
Builds a URL with the proper rewriting rules applied.
...
The URL must be either an absolute URL starting with a scheme (e.g. "http:// server/context/page.jsp") or a relative URL as defined by JSP 1.2 in JSP.2.2.1 "Relative URL Specification". As a consequence, an implementation must prepend the context path to a URL that starts with a slash (e.g. "/page2.jsp") so that such URLs can be properly interpreted by a client browser.

NOTE
Don't forget to use Taglib directive in your JSP to be able to reference JSTL tags. Also see an example JSP page here.

2) Using JSP Expression Language and implicit objects

An alternative solution is using Expression Language (EL) to add application context:

<link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/globalCSS.css" />

Here we have retrieved the context path from the request object. And to access the request object we have used the pageContext implicit object.

3) Using <c:set> tag from JSTL

DISCLAIMER
The idea of this solution was taken from here.

To make accessing the context path more compact than in the solution ?2, you can first use the JSTL <c:set> tag, that sets the value of an EL variable or the property of an EL variable in any of the JSP scopes (page, request, session, or application) for later access.

<c:set var="root" value="${pageContext.request.contextPath}"/>
...
<link type="text/css" rel="stylesheet" href="${root}/globalCSS.css" />

IMPORTANT NOTE
By default, in order to set the variable in such manner, the JSP that contains this set tag must be accessed at least once (including in case of setting the value in the application scope using scope attribute, like <c:set var="foo" value="bar" scope="application" />), before using this new variable. For instance, you can have several JSP files where you need this variable. So you must ether a) both set the new variable holding context path in the application scope AND access this JSP first, before using this variable in other JSP files, or b) set this context path holding variable in EVERY JSP file, where you need to access to it.

4) Using ServletContextListener

The more effective way to make accessing the context path more compact is to set a variable that will hold the context path and store it in the application scope using a Listener. This solution is similar to solution ?3, but the benefit is that now the variable holding context path is set right at the start of the web application and is available application wide, no need for additional steps.

We need a class that implements ServletContextListener interface. Here is an example of such class:

package com.example.listener;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;

@WebListener
public class AppContextListener implements ServletContextListener {

    @Override
    public void contextInitialized(ServletContextEvent event) {
        ServletContext sc = event.getServletContext();
        sc.setAttribute("ctx", sc.getContextPath());
    }

    @Override
    public void contextDestroyed(ServletContextEvent event) {}

}

Now in a JSP we can access this global variable using EL:

<link type="text/css" rel="stylesheet" href="${ctx}/globalCSS.css" />

NOTE
@WebListener annotation is available since Servlet version 3.0. If you use a servlet container or application server that supports older Servlet specifications, remove the @WebServlet annotation and instead configure the listener in the deployment descriptor (web.xml). Here is an example of web.xml file for the container that supports maximum Servlet version 2.5 (other configurations are omitted for the sake of brevity):

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">
    ...  
    <listener>
        <listener-class>com.example.listener.AppContextListener</listener-class>
    </listener>
    ...
</webapp>

5) Using scriptlets

As suggested by user @gavenkoa you can also use scriptlets like this:

<%= request.getContextPath() %>

For such a small thing it is probably OK, just note that generally the use of scriptlets in JSP is discouraged.

Conclusion

I personally prefer either the first solution (used it in my previous projects most of the time) or the second, as they are most clear, intuitive and unambiguous (IMHO). But you choose whatever suits you most.

Other thoughts

You can deploy your web app as the default application (i.e. in the default root context), so it can be accessed without specifying context path. For more info read the "Update" section here.

Mutations expect two arguments: state and payload, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.

The easiest way to pass a number of parameters is to destruct them:

mutations: {
    authenticate(state, { token, expiration }) {
        localStorage.setItem('token', token);
        localStorage.setItem('expiration', expiration);
    }
}

Then later on in your actions you can simply

store.commit('authenticate', {
    token,
    expiration,
});

My project use ButterKnife and Retro lambda, setting JavaVersion.VERSION_1_8 will not work. It always blames at ButterKnife static interface function until I found this Migrate from Retrolambda

TL;DR

Just add JavaVersion.VERSION_1_8 and completely REMOVE retrolambda from your project. It will build successfully.

just fetch specific node data and its working perfect for me

mFirebaseInstance.getReference("yourNodeName").getRef().addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {


        for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
            Log.e(TAG, "======="+postSnapshot.child("email").getValue());
            Log.e(TAG, "======="+postSnapshot.child("name").getValue());
        }
    }

    @Override
    public void onCancelled(DatabaseError error) {
        // Failed to read value
        Log.e(TAG, "Failed to read app title value.", error.toException());
    }
});

Can I use a field of the type ... and retrieve it after the GET / POST method ...

Yes (haven't you tried?)

Are there any other ways of using hidden fields in PHP?

You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.

Btw. input fiels have no end tag. So write either just <input ...> or as self-closing tag <input .../>.

You are looking for str.rsplit(), with a limit:

print x.rsplit('-', 1)[0]

.rsplit() searches for the splitting string from the end of input string, and the second argument limits how many times it'll split to just once.

Another option is to use str.rpartition(), which will only ever split just once:

print x.rpartition('-')[0]

For splitting just once, str.rpartition() is the faster method as well; if you need to split more than once you can only use str.rsplit().

Demo:

>>> x = 'http://test.com/lalala-134'
>>> print x.rsplit('-', 1)[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rsplit('-', 1)[0]
'something-with-a-lot-of'

and the same with str.rpartition()

>>> print x.rpartition('-')[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rpartition('-')[0]
'something-with-a-lot-of'

If you are on a POSIX system, you can use strcasecmp. This function is not part of standard C, though, nor is it available on Windows. This will perform a case-insensitive comparison on 8-bit chars, so long as the locale is POSIX. If the locale is not POSIX, the results are undefined (so it might do a localized compare, or it might not). A wide-character equivalent is not available.

Failing that, a large number of historic C library implementations have the functions stricmp() and strnicmp(). Visual C++ on Windows renamed all of these by prefixing them with an underscore because they aren’t part of the ANSI standard, so on that system they’re called _stricmp or _strnicmp. Some libraries may also have wide-character or multibyte equivalent functions (typically named e.g. wcsicmp, mbcsicmp and so on).

C and C++ are both largely ignorant of internationalization issues, so there's no good solution to this problem, except to use a third-party library. Check out IBM ICU (International Components for Unicode) if you need a robust library for C/C++. ICU is for both Windows and Unix systems.

Identifying the column is easy:

SELECT  *
FROM    ( SELECT    id,
                    time
          FROM      dbo.a
          UNION
          SELECT    id,
                    time
          FROM      dbo.b
        )
GROUP BY id

But it doesn't solve the main problem of this query: what's to be done with the second column values upon grouping by the first? Since (peculiarly!) you're using UNION rather than UNION ALL, you won't have entirely duplicated rows between the two subtables in the union, but you may still very well have several values of time for one value of the id, and you give no hint of what you want to do - min, max, avg, sum, or what?! The SQL engine should give an error because of that (though some such as mysql just pick a random-ish value out of the several, I believe sql-server is better than that).

So, for example, change the first line to SELECT id, MAX(time) or the like!

In a single line you could do:

private static File[] bar(){
    return new File[]{};
}

The most straight-forward approach is to do a second if-test but with the condition inverted. This technique is shorter, easier on the eyes, and easier to get right than a choose-when-otherwise nested block:

<xsl:variable name="CreatedDate" select="@createDate"/>
     <xsl:variable name="IDAppendedDate" select="2012-01-01" />
     <b>date: <xsl:value-of select="$CreatedDate"/></b> 
     <xsl:if test="$CreatedDate &gt; $IDAppendedDate">
        <h2> mooooooooooooo </h2>
     </xsl:if>
     <xsl:if test="$CreatedDate &lt;= $IDAppendedDate">
        <h2> dooooooooooooo </h2>
     </xsl:if>

Here's a real-world example of the technique being used in the style-sheet for a government website: http://w1.weather.gov/xml/current_obs/latest_ob.xsl

The simplest and easiest way is to execute your particular script with -NoExit param.

1.Open run box by pressing:

Win + R

2.Then type into input prompt:

PowerShell -NoExit "C:\folder\script.ps1"

and execute.

The usual pattern is EXISTS(subselect):

BEGIN
  IF EXISTS(SELECT name
              FROM test_table t
             WHERE t.id = x
               AND t.name = 'test')
  THEN
     ---
  ELSE
     ---
  END IF;

This pattern is used in PL/SQL, PL/pgSQL, SQL/PSM, ...

jQuery and console.log are unrelated entities, although useful when used together.

If you use a browser's built-in dev tools, console.log will log information about the object being passed to the log function.

If the console is not active, logging will not work, and may break your script. Be certain to check that the console exists before logging:

if (window.console) console.log('foo');

The shortcut form of this might be seen instead:

window.console&&console.log('foo');

There are other useful debugging functions as well, such as debug, dir and error. Firebug's wiki lists the available functions in the console api.

Officially, ConstraintLayout is much faster

In the N release of Android, the ConstraintLayout class provides similar functionality to RelativeLayout, but at a significantly lower cost.

Find a complete working example below:

The code by @Android is very good but has few issues, namely:

1. Populating to ListView code needs to be moved to onReceive of BroadCastReceiver where only the result will be available. In the case result is obtained at 2nd attempt.
2. BroadCastReceiver needs to be unregistered after the results are obtained.
3. size = size -1 seems unnecessary.

Find below the modified code of @Android as a working example:

Try putting it in quotes -- you're running into the shell's wildcard expansion, so what you're acually passing to find will look like:

find . -name bobtest.c cattest.c snowtest.c

...causing the syntax error. So try this instead:

find . -name '*test.c'

Note the single quotes around your file expression -- these will stop the shell (bash) expanding your wildcards.

I also integrated it with joor library

Just use

      Reflect.on(yourObject).set("finalFieldName", finalFieldValue);

Also I fixed an issue with override which the previous solutions seem to miss. However use this very carefully, only when there's no other good solution.

db.Lead.find(

{"name": {'$regex' : '.*' + "Ravi" + '.*'}},
{
"$or": [{
    'added_by':"[email protected]"
}, {
    'added_by':"[email protected]"
}]
}

);

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

What would be handy would be to apply the Camera position to a new plot. So I plot, then move the plot around with the mouse changing the distance. Then try to replicate the view including the distance on another plot. I find that axx.ax.get_axes() gets me an object with the old .azim and .elev.

IN PYTHON...

axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev
dst=axx.dist       # ALWAYS GIVES 10
#dst=ax1.axes.dist # ALWAYS GIVES 10
#dst=ax1.dist      # ALWAYS GIVES 10

Later 3d graph...

ax2.view_init(elev=ele, azim=azm) #Works!
ax2.dist=dst                       # works but always 10 from axx

EDIT 1... OK, Camera position is the wrong way of thinking concerning the .dist value. It rides on top of everything as a kind of hackey scalar multiplier for the whole graph.

This works for the magnification/zoom of the view:

xlm=ax1.get_xlim3d() #These are two tupples
ylm=ax1.get_ylim3d() #we use them in the next
zlm=ax1.get_zlim3d() #graph to reproduce the magnification from mousing
axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev

Later Graph...

ax2.view_init(elev=ele, azim=azm) #Reproduce view
ax2.set_xlim3d(xlm[0],xlm[1])     #Reproduce magnification
ax2.set_ylim3d(ylm[0],ylm[1])     #...
ax2.set_zlim3d(zlm[0],zlm[1])     #...

No, you never call the base class destructor, it is always called automatically like others have pointed out but here is proof of concept with results:

class base {
public:
    base()  { cout << __FUNCTION__ << endl; }
    ~base() { cout << __FUNCTION__ << endl; }
};

class derived : public base {
public:
    derived() { cout << __FUNCTION__ << endl; }
    ~derived() { cout << __FUNCTION__ << endl; } // adding call to base::~base() here results in double call to base destructor
};


int main()
{
    cout << "case 1, declared as local variable on stack" << endl << endl;
    {
        derived d1;
    }

    cout << endl << endl;

    cout << "case 2, created using new, assigned to derive class" << endl << endl;
    derived * d2 = new derived;
    delete d2;

    cout << endl << endl;

    cout << "case 3, created with new, assigned to base class" << endl << endl;
    base * d3 = new derived;
    delete d3;

    cout << endl;

    return 0;
}

The output is:

case 1, declared as local variable on stack

base::base
derived::derived
derived::~derived
base::~base


case 2, created using new, assigned to derive class

base::base
derived::derived
derived::~derived
base::~base


case 3, created with new, assigned to base class

base::base
derived::derived
base::~base

Press any key to continue . . .

If you set the base class destructor as virtual which one should, then case 3 results would be same as case 1 & 2.

As specified by the top answer, I used the following in the code behind the button control.

Private Sub btnClose_Click()
    Unload Me
End Sub

In doing so, it will not attempt to unload a control, but rather will unload the user form where the button control resides. The "Me" keyword refers to the user form object even when called from a control on the user form. If you are getting errors with this technique, there are a couple of possible reasons.

1. You could be entering the code in the wrong place (such as a separate module)

2. You might be using an older version of Office. I'm using Office 2013. I've noticed that VBA changes over time.

From my experience, the use of the the DoCmd.... method is more specific to the macro features in MS Access, but not commonly used in Excel VBA.

Under normal (out of the box) conditions, the code above should work just fine.

If i understand you correctly, (i probably don't)

'SELECT @RowCount = COUNT(*)
                   FROM dbo.Comm_Services
                   WHERE CompanyId = ' + CAST(@CompanyId AS CHAR) + '
                   AND ' + @condition

Do not use floats to store fixed-point, accuracy-required data. This example shows how to convert a float to NVARCHAR(50) properly, while also showing why it is a bad idea to use floats for precision data.

create table #f ([Column_Name] float)
insert #f select 9072351234
insert #f select 907235123400000000000

select
    cast([Column_Name] as nvarchar(50)),
    --cast([Column_Name] as int), Arithmetic overflow
    --cast([Column_Name] as bigint), Arithmetic overflow
    CAST(LTRIM(STR([Column_Name],50)) AS NVARCHAR(50))
from #f

Output

9.07235e+009    9072351234
9.07235e+020    907235123400000010000

You may notice that the 2nd output ends with '10000' even though the data we tried to store in the table ends with '00000'. It is because float datatype has a fixed number of significant figures supported, which doesn't extend that far.

SELECT @variable1 = col1, @variable2 = col2
FROM table1

Code

PL_CONNECT_STRING="$DB_USERNAME/$DB_PASSWORD@$DB_SERVICE"

OUTPUT=$(sqlplus -s $PL_CONNECT_STRING <<-END-OF-SQL
           select count(*) from table;
exit;
END-OF-SQL)
echo "COMPLETED GATHER STATS $OUTPUT";

Explanation:

PL_CONNECT_STRING carry database username, password and it service name

sqlplus is used to connect the Database with PL_CONNECT_STRING details

END-OF-SQL tag contain the query which you want to execute

echo is used to print the output of the query

NOTE: You can give multiple Query inside the END-OF-SQL tag, so its useful for batch execution as well

Both John Conde's and ryeballar's answers are correct and will work.

If you want to get too geeky:

• John's has the downside that it has to make two decisions per $digest loop (it has to decide whether to add/remove center and it has to decide whether to add/remove left), when clearly only one is needed.

• Ryeballar's relies on the ternary operator which is probably going to be removed at some point (because the view should not contain any logic). (We can't be sure it will indeed be removed and it probably won't be any time soon, but if there is a more "safe" solution, why not ?)

So, you can do the following as an alternative:

ng-class="{true:'center',false:'left'}[page.isSelected(1)]"

Json stands for JavaScript Object Notation really all json is are javascript objects so your array is in json form already. To write it out in a div you could do a bunch of things one of the easiest I think would be:

 objectDiv.innerHTML = filter;

where objectDiv is the div you want selected from the DOM using jquery. If you wanted to list parts of the array out you could access them since it is a javascript object like so:

 objectDiv.innerHTML = filter.dvals.valueToDisplay; //brand or count depending.

edit: anything you want to be a string but is not currently (which is rare javascript treats almost everything as a string) just use the toString() function built in. so line above if you needed it would be filter.dvals.valueToDisplay.toString();

second edit to clarify: this answer is in response to the OP's comments and not completely to his original question.

Mock is a method/object that simulates the behavior of a real method/object in controlled ways. Mock objects are used in unit testing.

Often a method under a test calls other external services or methods within it. These are called dependencies. Once mocked, the dependencies behave the way we defined them.

With the dependencies being controlled by mocks, we can easily test the behavior of the method that we coded. This is Unit testing.

What is the purpose of mock objects?

Mocks vs stubs

Unit tests vs Functional tests

func viewDidLoad(){
let homeBtn: UIButton = UIButton(type: UIButtonType.custom)

        homeBtn.setImage(UIImage(named: "Home.png"), for: [])

        homeBtn.addTarget(self, action: #selector(homeAction), for: UIControlEvents.touchUpInside)

        homeBtn.frame = CGRect(x: 0, y: 0, width: 30, height: 30)

        let homeButton = UIBarButtonItem(customView: homeBtn)


        let backBtn: UIButton = UIButton(type: UIButtonType.custom)

        backBtn.setImage(UIImage(named: "back.png"), for: [])

        backBtn.addTarget(self, action: #selector(backAction), for: UIControlEvents.touchUpInside)

        backBtn.frame = CGRect(x: -10, y: 0, width: 30, height: 30)

        let backButton = UIBarButtonItem(customView: backBtn)
        self.navigationItem.setLeftBarButtonItems([backButton,homeButton], animated: true)
}

}

I add double backslash to the dot to make it work. Cheer.

var st = "okay.this.is.a.string";
var Re = new RegExp("\\.","g");
st = st.replace(Re," ");
alert(st);

OpenJDK is a reference model and open source, while Oracle JDK is an implementation of the OpenJDK and is not open source. Oracle JDK is more stable than OpenJDK.

OpenJDK is released under GPL v2 license whereas Oracle JDK is licensed under Oracle Binary Code License Agreement.

OpenJDK and Oracle JDK have almost the same code, but Oracle JDK has more classes and some bugs fixed.

So if you want to develop enterprise/commercial software I would suggest to go for Oracle JDK, as it is thoroughly tested and stable.

I have faced lot of problems with application crashes using OpenJDK, which are fixed just by switching to Oracle JDK

If you will be doing many searches of the array, AND matching always is defined as string equivalence, then you can normalize your data and use a hash.

my @strings = qw( aAa Bbb cCC DDD eee );

my %string_lut;

# Init via slice:
@string_lut{ map uc, @strings } = ();

# or use a for loop:
#    for my $string ( @strings ) {
#        $string_lut{ uc($string) } = undef;
#    }


#Look for a string:

my $search = 'AAa';

print "'$string' ", 
    ( exists $string_lut{ uc $string ? "IS" : "is NOT" ),
    " in the array\n";

Let me emphasize that doing a hash lookup is good if you are planning on doing many lookups on the array. Also, it will only work if matching means that $foo eq $bar, or other requirements that can be met through normalization (like case insensitivity).

You need to have the private key of the signing certificate in the keychain along with the public key. Have you created the certificate using the same Mac (keychain) ?

Solution #1:

• Revoke the signing certificate (reset) from apple developer portal
• Create the signing certificate again on the same mac (keychain). Then you will have the private key for the signing certificate!

Solution #2:

• Export the signing identities from the origin xCode
• Import the signing on your xCode

finalString = "physical" + System.lineSeparator() + "distancing";

If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform property:

.myclass {
    text-transform: lowercase;
}

See https://developer.mozilla.org/en/CSS/text-transform for more info.

However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.

The error is because of the sql mode which can be strict mode as per latest MYSQL 5.7 documentation.

Hope it helps.

This is something that is done by Django itself when building a form from a model. It is using the _meta attribute, but as Bernhard noted, it uses both _meta.fields and _meta.many_to_many. Looking at django.forms.models.fields_for_model, this is how you could do it:

opts = model._meta
for f in sorted(opts.fields + opts.many_to_many):
    print '%s: %s' % (f.name, f)

Could you try something like this for example I think what you are wanting to utilize is the port.ReadExisting() Method

 using System;
 using System.IO.Ports;

 class SerialPortProgram 
 { 
  // Create the serial port with basic settings 
    private SerialPort port = new   SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One); 
    [STAThread] 
    static void Main(string[] args) 
    { 
      // Instatiate this 
      SerialPortProgram(); 
    } 

    private static void SerialPortProgram() 
    { 
        Console.WriteLine("Incoming Data:");
         // Attach a method to be called when there
         // is data waiting in the port's buffer 
        port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); 
        // Begin communications 
        port.Open(); 
        // Enter an application loop to keep this thread alive 
        Console.ReadLine();
     } 

    private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) 
    { 
       // Show all the incoming data in the port's buffer
       Console.WriteLine(port.ReadExisting()); 
    } 
}

Or is you want to do it based on what you were trying to do , you can try this

public class MySerialReader : IDisposable
{
  private SerialPort serialPort;
  private Queue<byte> recievedData = new Queue<byte>();

  public MySerialReader()
  {
    serialPort = new SerialPort();
    serialPort.Open();
    serialPort.DataReceived += serialPort_DataReceived;
  }

  void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
  {
    byte[] data = new byte[serialPort.BytesToRead];
    serialPort.Read(data, 0, data.Length);
    data.ToList().ForEach(b => recievedData.Enqueue(b));
    processData();
  }

  void processData()
  {
    // Determine if we have a "packet" in the queue
    if (recievedData.Count > 50)
    {
        var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
    }
  }

  public void Dispose()
  {
        if (serialPort != null)
        {
            serialPort.Dispose();
        }
  }

How a character is represented is up to the renderer, but the server may also strip out certain characters before sending the document.

You can also have untitled YouTube videos like https://www.youtube.com/watch?v=dmBvw8uPbrA by using the Unicode character ZERO WIDTH NON-JOINER (U+200C), or ‌ in HTML. The code block below should contain that character:

While the original question may not have been specific to a web service, here is a complete testWebService you can add to display a web service non-cached response plus the file version. We use file version instead of assembly version because we want to know a version, but with all assembly versions 1.0.0.0, the web site can be easily patched (signing and demand link still active!). Replace @Class@ with the name of the web api controller this service is embedded in. It's good for a go/nogo on a web service plus a quick version check.

  [Route("api/testWebService")]
  [AllowAnonymous]
  [HttpGet]
  public HttpResponseMessage TestWebService()
  {
      HttpResponseMessage responseMessage = Request.CreateResponse(HttpStatusCode.OK);
      string loc = Assembly.GetAssembly(typeof(@Class@)).Location;
      FileVersionInfo versionInfo = FileVersionInfo.GetVersionInfo(loc);
      responseMessage.Content = new StringContent($"<h2>The XXXXX web service GET test succeeded.</h2>{DateTime.Now}<br/><br/>File Version: {versionInfo.FileVersion}");
      responseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
      Request.RegisterForDispose(responseMessage);
      return responseMessage;
  }

I found it also necessary to add the following to web.config under configuration to make it truly anonymous

<location path="api/testwebservice">
    <system.web>
        <authorization>
            <allow users="*" />
        </authorization>
    </system.web>
</location>

With help of an online xpath tester I'm writing this answer...
For this:

<table id="t2"><tbody>
<tr><td>123</td><td>other</td></tr>
<tr><td>foo</td><td>columns</td></tr>
<tr><td>bar</td><td>are</td></tr>
<tr><td>xyz</td><td>ignored</td></tr>
</tbody></table>

the following xpath:

id("t2") / tbody / tr / td[1]

outputs:

123
foo
bar
xyz

Since 1 means select all td elements which are the first child of their own direct parent.
But the following xpath:

(id("t2") / tbody / tr / td)[1]

outputs:

123

IN the below code you are calling the overriden method .equals().

public boolean equals2(Object object2) { if(a.equals(object2)) { // here you are calling the overriden method, that is why you getting false 2 times. return true; } else return false; }

Either override the OnFormClosing or register for the event FormClosing.

This is an example of overriding the OnFormClosing function in the derived form:

protected override void OnFormClosing(FormClosingEventArgs e)
{
   e.Cancel = true;
}

This is an example of the handler of the event to stop the form from closing which can be in any class:

private void FormClosing(object sender,FormClosingEventArgs e)
{  
   e.Cancel = true;
}

To get more advanced, check the CloseReason property on the FormClosingEventArgs to ensure the appropriate action is performed. You might want to only do the alternative action if the user tries to close the form.

Here is a function that parses without raising errors. It handles obvious cases returns None on failure (handles up to 2000 '-/+' signs by default on CPython!):

#!/usr/bin/env python

def get_int(number):
    splits = number.split('.')
    if len(splits) > 2:
        # too many splits
        return None
    if len(splits) == 2 and splits[1]:
        # handle decimal part recursively :-)
        if get_int(splits[1]) != 0:
            return None

    int_part = splits[0].lstrip("+")
    if int_part.startswith('-'):
        # handle minus sign recursively :-)
        return get_int(int_part[1:]) * -1
    # successful 'and' returns last truth-y value (cast is always valid)
    return int_part.isdigit() and int(int_part)

Some tests:

tests = ["0", "0.0", "0.1", "1", "1.1", "1.0", "-1", "-1.1", "-1.0", "-0", "--0", "---3", '.3', '--3.', "+13", "+-1.00", "--+123", "-0.000"]

for t in tests:
    print "get_int(%s) = %s" % (t, get_int(str(t)))

Results:

get_int(0) = 0
get_int(0.0) = 0
get_int(0.1) = None
get_int(1) = 1
get_int(1.1) = None
get_int(1.0) = 1
get_int(-1) = -1
get_int(-1.1) = None
get_int(-1.0) = -1
get_int(-0) = 0
get_int(--0) = 0
get_int(---3) = -3
get_int(.3) = None
get_int(--3.) = 3
get_int(+13) = 13
get_int(+-1.00) = -1
get_int(--+123) = 123
get_int(-0.000) = 0

For your needs you can use:

def int_predicate(number):
     return get_int(number) is not None

• Setting the x-axis with np.arange(0, 1, 0.001) gives an array from 0 to 1 in 0.001 increments.
  • x = np.arange(0, 1, 0.001) returns an array of 1000 points from 0 to 1, and y = np.sin(2*np.pi*x) you will get the sin wave from 0 to 1 sampled 1000 times

I hope this will help:

import matplotlib.pyplot as plt
import numpy as np


Fs = 8000
f = 5
sample = 8000
x = np.arange(sample)
y = np.sin(2 * np.pi * f * x / Fs)
plt.plot(x, y)
plt.xlabel('sample(n)')
plt.ylabel('voltage(V)')
plt.show()

P.S.: For comfortable work you can use The Jupyter Notebook.

Based on the previous answers, here is a simple alternative way of printing the R-version, followed by the name and version of each package loaded in the namespace. It works in the Jupyter notebook, where I had troubles running sessionInfo() and R --version.

print(paste("R", getRversion()))
print("-------------")
for (package_name in sort(loadedNamespaces())) {
    print(paste(package_name, packageVersion(package_name)))
}

Out:

[1] "R 3.2.2"
[1] "-------------"
[1] "AnnotationDbi 1.32.2"
[1] "Biobase 2.30.0"
[1] "BiocGenerics 0.16.1"
[1] "BiocParallel 1.4.3"
[1] "DBI 0.3.1"
[1] "DESeq2 1.10.0"
[1] "Formula 1.2.1"
[1] "GenomeInfoDb 1.6.1"
[1] "GenomicRanges 1.22.3"
[1] "Hmisc 3.17.0"
[1] "IRanges 2.4.6"
[1] "IRdisplay 0.3"
[1] "IRkernel 0.5"

var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';
var decoded = $('<textarea/>').html(text).text();
alert(decoded);

This sets the innerHTML of a new element (not appended to the page), causing jQuery to decode it into HTML, which is then pulled back out with .text().

What type of allocation functions are you using? I recently hit a similar error using the Heap* style allocation functions.

It turned out that I was mistakenly creating the heap with the HEAP_NO_SERIALIZE option. This essentially makes the Heap functions run without thread safety. It's a performance improvement if used properly but shouldn't ever be used if you are using HeapAlloc in a multi-threaded program [1]. I only mention this because your post mentions you have a multi-threaded app. If you are using HEAP_NO_SERIALIZE anywhere, delete that and it will likely fix your problem.

[1] There are certain situations where this is legal, but it requires you to serialize calls to Heap* and is typically not the case for multi-threaded programs.

Installing libffi-dev and re-installing python3.7 fixed the problem for me.

to cleanly build py 3.7 libffi-dev is required or else later stuff will fail

If using RHEL/Fedora:

yum install libffi-devel

or

sudo dnf install libffi-devel

If using Debian/Ubuntu:

sudo apt-get install libffi-dev

Exporting each variable from your variables file. Then importing them with * as in your other file and exporting the as a constant from that file will give you a dynamic object with the named exports from the first file being attributes on the object exported from the second.

Variables.js

export const var1 = 'first';
export const var2 = 'second':
...
export const varN = 'nth';

Other.js

import * as vars from './Variables';

export const Variables = vars;

Third.js

import { Variables } from './Other';

Variables.var2 === 'second'

I've faced same problem and came across to this thread but my problem was with upstream. Below git command worked for me.

Syntax

git checkout {remoteName}/{branch} -- {../path/file.js}

Example

git checkout upstream/develop -- public/js/index.js

The infinite loop is a result of an On Error Resume Next statement somewhere higher up in your code. Get rid of it now. If your code only runs with On Error Resume Next in effect, it needs instant and complete overhaul.

And while you are at it, place an Option Explicit on top of yor module. It forces you to declare all variables, a safeguard against annoying bugs that are the result of mis-typed variable names. (You can modify the VBA editor preferences to have that option set automatically the next time, which is highly recommended.)

The immediate problem with your code is that a cell is an object, and objects cannot be trimmed. You want to trim the text of the cell, so you must do so:

cell.Text = Trim(cell.Text)

You can directly add a constraint for table

ALTER TABLE TableName
ADD CONSTRAINT ConstraintName PRIMARY KEY(ColumnName)
GO 

Make sure your primary key column should not have any null values.

Option 2:

you can change your SQL Management Studio Options like

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

You can look for regular expression

Regex.IsMatch(str, @"^[a-zA-Z]+$");

.yourClass>tbody>tr>td{border: 1px solid #ffffff !important;}

Without installing a screenshot autosave utility, yes you do. There are several utilities you can find however folr doing this.

For example: http://www.screenshot-utility.com/

8 letters from the alphabet - All caps:

UPDATE `tablename` SET `tablename`.`randomstring`= concat(CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25)))CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))),CHAR(FLOOR(65 + (RAND() * 25))));

You could use python-benedict, it's a dict subclass.

Installation: pip install python-benedict

from benedict import benedict

dict_you_want = benedict(your_dict).subset(keys=['firstname', 'lastname', 'email'])

It's open-source on GitHub: https://github.com/fabiocaccamo/python-benedict

^{Disclaimer: I'm the author of this library.}

This should do the trick:

pw_bytes.decode("utf-8")

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

You can also face this situation if your upstream server uses a domain name, and its IP address changes (e.g.: your upstream points to an AWS Elastic Load Balancer)

The problem is that nginx will resolve the IP address once, and keep it cached for subsequent requests until the configuration is reloaded.

You can tell nginx to use a name server to re-resolve the domain once the cached entry expires:

location /mylocation {
    # use google dns to resolve host after IP cached expires
    resolver 8.8.8.8;
    set $upstream_endpoint http://your.backend.server/;
    proxy_pass $upstream_endpoint;
}

The docs on proxy_pass explain why this trick works:

Parameter value can contain variables. In this case, if an address is specified as a domain name, the name is searched among the described server groups, and, if not found, is determined using a resolver.

Kudos to "Nginx with dynamic upstreams" (tenzer.dk) for the detailed explanation, which also contains some relevant information on a caveat of this approach regarding forwarded URIs.

If you're checking for explicit types, why are you declaring those variables as T's?

T HowToCast<T>(T t)
{
    if (typeof(T) == typeof(string))
    {
        var newT1 = "some text";
        var newT2 = t;  //this builds but I'm not sure what it does under the hood.
        var newT3 = t.ToString();  //for sure the string you want.
    }

    return t;
}

There are some great example already given here. Just adding a simple example to push associative array elements to root numeric index index.

`$intial_content = array();

if (true) {
 $intial_content[] = array('name' => 'xyz', 'content' => 'other content');
}`

public class Main {
    public static void main(String[] args) {
        int i = 10;
        int j = 20;
        int k = 5;
        int x = (i > j && i > k) ? i : (j > k) ? j : k;
        int y = (i < j && i < k) ? i : (j < k) ? j : k;
        System.out.println("Largetst Number : "+x);
        System.out.println("Smallest Number : "+y);
    }
}

Output:
Largetst Number : 20
Smallest Number : 5

I tried all above but nothing helps, at last i just figured out that under setting >> apps, device still has an entry for uninstalled application as disabled, i just uninstalled from there and it starts working.

In oracle, generally speaking, there are number of facts that I will mention in following section:

• Each database can have many Schema/User (Logical division).
• Each database can have many tablespaces (Logical division).
• A schema is the set of objects (tables, indexes, views, etc) that belong to a user.
• In Oracle, a user can be considered the same as a schema.
• A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group all of an application’s objects to simplify some administrative operations. You may have a tablespace for application data and an additional one for application indexes.

Therefore, your question, "to see all tablespaces and datafiles belong to SCOTT" is s bit wrong.

However, there are some DBA views encompass information about all database objects, regardless of the owner. Only users with DBA privileges can access these views: DBA_DATA_FILES, DBA_TABLESPACES, DBA_FREE_SPACE, DBA_SEGMENTS.

So, connect to your DB as sysdba and run query through these helpful views. For example this query can help you to find all tablespaces and their data files that objects of your user are located:

SELECT DISTINCT sgm.TABLESPACE_NAME , dtf.FILE_NAME
FROM DBA_SEGMENTS sgm
JOIN DBA_DATA_FILES dtf ON (sgm.TABLESPACE_NAME = dtf.TABLESPACE_NAME)
WHERE sgm.OWNER = 'SCOTT'

Added this answer because none of other available above worked for me.

In my case something even more weird was happening (Django 1.7 Version), In my models.py I had an "extra" line at the end of my file (it was a blank line) and when I executed the python manage.py makemigrations command the result was: "no changes detected".

To fix this I deleted this "blank line" that was at the end of my models.py file and I did run the command again, everything was fixed and all the changes made to models.py were detected!

I want to know how to check whether MySQL strict mode is on or off in localhost(xampp).

SHOW VARIABLES LIKE 'sql_mode';

If result has "STRICT_TRANS_TABLES", then it's ON. Otherwise, it's OFF.

If on then for what modes and how to off.

If off then how to on.

For Windows,

1. Go to C:\Program Files\MariaDB XX.X\data
2. Open the my.ini file.
3. *On the line with "sql_mode", modify the value to turn strict mode ON/OFF.
4. Save the file
5. **Restart the MySQL service
6. Run SHOW VARIABLES LIKE 'sql_mode' again to see if it worked;

*3.a. To turn it ON, add STRICT_TRANS_TABLES on that line like this: sql_mode=STRICT_TRANS_TABLES. *If there are other values already, add a comma after this then join with the rest of the value.

*3.b. To turn it OFF, simply remove STRICT_TRANS_TABLES from value. *Remove the additional comma too if there is one.

**6. To restart the MySQL service on your computer,

1. Open the Run command window (press WINDOWS + R button).
2. Type services.msc
3. Click OK
4. Right click on the Name MySQL
5. Click Restart

If you use Excel, then the command would be Find and MID. Here is what it would look like in Powershell.

 $text = "asdfNAME=PC123456<>Diweursejsfdjiwr"

asdfNAME=PC123456<>Diweursejsfdjiwr - Randon line of text, we want PC123456

 $text.IndexOf("E=")

7 - this is the "FIND" command for Powershell

 $text.substring(10,5)

C1234 - this is the "MID" command for Powershell

 $text.substring($text.IndexOf("E=")+2,8)

PC123456 - tada it has found and cut our text

This Worked for me. i implemented this solution in reactJS

const requestOptions = {`enter code here`
method: 'GET',
headers: { 'Content-Type': 'application/json' }
};

fetch(`${url}`, requestOptions)
.then((res) => {
    return res.blob();
})
.then((blob) => {
    const href = window.URL.createObjectURL(blob);
    const link = document.createElement('a');
    link.href = href;
    link.setAttribute('download', 'config.json'); //or any other extension
    document.body.appendChild(link);
    link.click();
})
.catch((err) => {
    return Promise.reject({ Error: 'Something Went Wrong', err });
})

add semi-colon the line before:

$total_pages = ceil($total_result / $per_page);

Commons-net surely. :) Most open source projects use it these days.

You can use html and be a boss with simple things :

<embed src="music.mp3" width="3000" height="200" controls>

Another way is to simply pass the json string as a dict to the constructor of your object. For example your object is:

class Payload(object):
    def __init__(self, action, method, data, *args, **kwargs):
        self.action = action
        self.method = method
        self.data = data

And the following two lines of python code will construct it:

j = json.loads(yourJsonString)
payload = Payload(**j)

Basically, we first create a generic json object from the json string. Then, we pass the generic json object as a dict to the constructor of the Payload class. The constructor of Payload class interprets the dict as keyword arguments and sets all the appropriate fields.

The straight answer is already in a duplicate question: Why does the jquery change event not trigger when I set the value of a select using val()?

As you probably know setting the value of the select doesn't trigger the change() event, if you're looking for an event that is fired when an element's value has been changed through JS there isn't one.

If you really want to do this I guess the only way is to write a function that checks the DOM on an interval and tracks changed values, but definitely don't do this unless you must (not sure why you ever would need to)

Added this solution:
Another possible solution would be to create your own .val() wrapper function and have it trigger a custom event after setting the value through .val(), then when you use your .val() wrapper to set the value of a <select> it will trigger your custom event which you can trap and handle.

Be sure to return this, so it is chainable in jQuery fashion

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

SQL Fiddle Demo with both

As @kosev said in his answer you can use JobIntentService. But I use an alternative solution - I catch IllegalStateException and start the service as foreground. For example, this function starts my service:

@JvmStatic
protected fun startService(intentAction: String, serviceType: Class<*>, intentExtraSetup: (Intent) -> Unit) {
    val context = App.context
    val intent = Intent(context, serviceType)
    intent.action = intentAction
    intentExtraSetup(intent)
    intent.putExtra(NEED_FOREGROUND_KEY, false)

    try {
        context.startService(intent)
    }
    catch (ex: IllegalStateException) {
        intent.putExtra(NEED_FOREGROUND_KEY, true)
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            context.startForegroundService(intent)
        }
        else {
            context.startService(intent)
        }
    }
}

and when I process Intent I do such thing:

override fun onHandleIntent(intent: Intent?) {
    val needToMoveToForeground = intent?.getBooleanExtra(NEED_FOREGROUND_KEY, false) ?: false
    if(needToMoveToForeground) {
        val notification = notificationService.createSyncServiceNotification()
        startForeground(notification.second, notification.first)

        isInForeground = true
    }

    intent?.let {
        getTask(it)?.process()
    }
}

I understand this is quite an old question. But would like to clarify that:

Date d = new Date() 

is depriciated in the current versions of Java. The recommended way is using a calendar object. For eg:

Calendar cal = Calendar.getInstance();
Date currentTime = cal.getTime();

I hope this will help people who may refer this question in future. Thank you all.

If the number of list items is fixed you can use the adjacent selector, e.g. if you only have three <li> elements, you can select the last <li> with:

#nav li+li+li {
    border-bottom: 1px solid #b5b5b5;
}

In c/cpp there is no shortcut but to initialize all the arrays with the zero subscript.Ex:

  int arr[10] = {0};

But in java there is a magic tool called Arrays.fill() which will fill all the values in an array with the integer of your choice.Ex:

  import java.util.Arrays;

    public class Main
    {
      public static void main(String[] args)
       {
         int ar[] = {2, 2, 1, 8, 3, 2, 2, 4, 2};
         Arrays.fill(ar, 10);
         System.out.println("Array completely filled" +                          
            " with 10\n" + Arrays.toString(ar));
   }
 }

Using jj

In my case, the .vimrc (or in gVim it is in _vimrc) setting below.

inoremap jj <Esc>   """ jj key is <Esc> setting

For reference, this is the groovy script I've used to generate this output:

@Grab('org.liquibase:liquibase-core:3.5.1')

    def datatype = it.newInstance()
    datatype.finishInitialization("")
    println datatype.name
    databases.each { println "$it.simpleName: ${datatype.toDatabaseDataType(it.newInstance())}"}
    println ''
}

I sorted this problem as verifying the json from JSONLint.com and then, correcting it. And this is code for the same.

String jsonStr = "[{\r\n" + "\"name\":\"New York\",\r\n" + "\"number\": \"732921\",\r\n"+ "\"center\": {\r\n" + "\"latitude\": 38.895111,\r\n"  + " \"longitude\": -77.036667\r\n" + "}\r\n" + "},\r\n" + " {\r\n"+ "\"name\": \"San Francisco\",\r\n" +\"number\":\"298732\",\r\n"+ "\"center\": {\r\n" + "    \"latitude\": 37.783333,\r\n"+ "\"longitude\": -122.416667\r\n" + "}\r\n" + "}\r\n" + "]";

ObjectMapper mapper = new ObjectMapper();
MyPojo[] jsonObj = mapper.readValue(jsonStr, MyPojo[].class);

for (MyPojo itr : jsonObj) {
    System.out.println("Val of name is: " + itr.getName());
    System.out.println("Val of number is: " + itr.getNumber());
    System.out.println("Val of latitude is: " + 
        itr.getCenter().getLatitude());
    System.out.println("Val of longitude is: " + 
        itr.getCenter().getLongitude() + "\n");
}

Note: MyPojo[].class is the class having getter and setter of json properties.

Result:

Val of name is: New York
Val of number is: 732921
Val of latitude is: 38.895111
Val of longitude is: -77.036667
Val of name is: San Francisco
Val of number is: 298732
Val of latitude is: 37.783333
Val of longitude is: -122.416667

Non programmatically, you can just open the archive using the 7zip UI to add/remove or extract/replace files without the structure changing. I didn't know it was a problem using other things until now :)

If you don't want to deal with interactive mode then do this:

Update your last pushed commit

git commit --amend -m "New commit message."

Push your new commit message (this will replace the old last commit message to this new one)

git push origin --force **branch-name**

More on this - https://linuxize.com/post/change-git-commit-message/

The effect you want is to treat the NULL as the largest possible date then replace it with NULL again upon completion:

SELECT RecordId, MIN(StartDate), NULLIF(MAX(COALESCE(EndDate,'9999-12-31')),'9999-12-31') 
  FROM tmp GROUP BY RecordId

Per your fiddle this will return the exact results you specify under all conditions.

mode: 'no-cors' won’t magically make things work. In fact it makes things worse, because one effect it has is to tell browsers, “Block my frontend JavaScript code from looking at contents of the response body and headers under all circumstances.” Of course you almost never want that.

What happens with cross-origin requests from frontend JavaScript is that browsers by default block frontend code from accessing resources cross-origin. If Access-Control-Allow-Origin is in a response, then browsers will relax that blocking and allow your code to access the response.

But if a site sends no Access-Control-Allow-Origin in its responses, your frontend code can’t directly access responses from that site. In particular, you can’t fix it by specifying mode: 'no-cors' (in fact that’ll ensure your frontend code can’t access the response contents).

However, one thing that will work: if you send your request through a CORS proxy.

You can also easily deploy your own proxy to Heroku in literally just 2-3 minutes, with 5 commands:

git clone https://github.com/Rob--W/cors-anywhere.git
cd cors-anywhere/
npm install
heroku create
git push heroku master

After running those commands, you’ll end up with your own CORS Anywhere server running at, for example, https://cryptic-headland-94862.herokuapp.com/.

Prefix your request URL with your proxy URL; for example:

https://cryptic-headland-94862.herokuapp.com/https://example.com

Adding the proxy URL as a prefix causes the request to get made through your proxy, which then:

1. Forwards the request to https://example.com.
2. Receives the response from https://example.com.
3. Adds the Access-Control-Allow-Origin header to the response.
4. Passes that response, with that added header, back to the requesting frontend code.

The browser then allows the frontend code to access the response, because that response with the Access-Control-Allow-Origin response header is what the browser sees.

This works even if the request is one that triggers browsers to do a CORS preflight OPTIONS request, because in that case, the proxy also sends back the Access-Control-Allow-Headers and Access-Control-Allow-Methods headers needed to make the preflight successful.

I can hit this endpoint, http://catfacts-api.appspot.com/api/facts?number=99 via Postman

https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS explains why it is that even though you can access the response with Postman, browsers won’t let you access the response cross-origin from frontend JavaScript code running in a web app unless the response includes an Access-Control-Allow-Origin response header.

http://catfacts-api.appspot.com/api/facts?number=99 has no Access-Control-Allow-Origin response header, so there’s no way your frontend code can access the response cross-origin.

Your browser can get the response fine and you can see it in Postman and even in browser devtools—but that doesn’t mean browsers will expose it to your code. They won’t, because it has no Access-Control-Allow-Origin response header. So you must instead use a proxy to get it.

The proxy makes the request to that site, gets the response, adds the Access-Control-Allow-Origin response header and any other CORS headers needed, then passes that back to your requesting code. And that response with the Access-Control-Allow-Origin header added is what the browser sees, so the browser lets your frontend code actually access the response.

So I am trying to pass in an object, to my Fetch which will disable CORS

You don’t want to do that. To be clear, when you say you want to “disable CORS” it seems you actually mean you want to disable the same-origin policy. CORS itself is actually a way to do that — CORS is a way to loosen the same-origin policy, not a way to restrict it.

But anyway, it’s true you can — in just your local environment — do things like give your browser runtime flags to disable security and run insecurely, or you can install a browser extension locally to get around the same-origin policy, but all that does is change the situation just for you locally.

No matter what you change locally, anybody else trying to use your app is still going to run into the same-origin policy, and there’s no way you can disable that for other users of your app.

You most likely never want to use mode: 'no-cors' in practice except in a few limited cases, and even then only if you know exactly what you’re doing and what the effects are. That’s because what setting mode: 'no-cors' actually says to the browser is, “Block my frontend JavaScript code from looking into the contents of the response body and headers under all circumstances.” In most cases that’s obviously really not what you want.

As far as the cases when you would want to consider using mode: 'no-cors', see the answer at What limitations apply to opaque responses? for the details. The gist of it is that the cases are:

• In the limited case when you’re using JavaScript to put content from another origin into a <script>, <link rel=stylesheet>, <img>, <video>, <audio>, <object>, <embed>, or <iframe> element (which works because embedding of resources cross-origin is allowed for those) — but for some reason you don’t want to or can’t do that just by having the markup of the document use the resource URL as the href or src attribute for the element.

• When the only thing you want to do with a resource is to cache it. As alluded to in the answer What limitations apply to opaque responses?, in practice the scenario that applies to is when you’re using Service Workers, in which case the API that’s relevant is the Cache Storage API.

But even in those limited cases, there are some important gotchas to be aware of; see the answer at What limitations apply to opaque responses? for the details.

I have also tried to pass in the object { mode: 'opaque'}

There is no mode: 'opaque' request mode — opaque is instead just a property of the response, and browsers set that opaque property on responses from requests sent with the no-cors mode.

But incidentally the word opaque is a pretty explicit signal about the nature of the response you end up with: “opaque” means you can’t see it.

Use copyOfRange method from java.util.Arrays class:

int[] newArray = Arrays.copyOfRange(oldArray, startIndex, endIndex);

The most common reasons for me are so that:

1. The layout can have a fixed width (yes, I know, I do a lot of work for designers who love fixed widths), and
2. So the layout can be centered by applying text-align: center to the body and then margin: auto to the left and right of the container div.

On Debian we use the start-stop-daemon utility, which handles pid-files, changing the user, putting the daemon into background and much more.

I'm not familiar with RedHat, but the daemon utility that you are already using (which is defined in /etc/init.d/functions, btw.) is mentioned everywhere as the equivalent to start-stop-daemon, so either it can also change the uid of your program, or the way you do it is already the correct one.

If you look around the net, there are several ready-made wrappers that you can use. Some may even be already packaged in RedHat. Have a look at daemonize, for example.

This is a very simple to create file in git bash at first write touch then file name with extension

for example

touch filename.extension

You really need to check if the string's length is greater to or equal to 38.

You can use flex as below:

.parent-container {
    display: flex;
    flex-direction: column;
    flex-wrap: wrap;
    max-height: 100px;
}

Adjust max-height property as per need to generate another columns

add "id='myiframe'" to the iframe, then use this script :

<script>

function f1()
{
 var x=document.getElementById("myiframe");
   x.src=x.src+Math.floor(random()%100000);
}

setInterval(f1,30*1000);

</script>

For simple commands you can use:

ssh <ssh_args> command1 '&&' command2

or

ssh <ssh_args> command1 \&\& command2

@alvas's answer does the job but it can be done way faster. Assuming that you have documents: a list of strings.

from nltk.corpus import stopwords
from nltk.tokenize import wordpunct_tokenize

stop_words = set(stopwords.words('english'))
stop_words.update(['.', ',', '"', "'", '?', '!', ':', ';', '(', ')', '[', ']', '{', '}']) # remove it if you need punctuation 

for doc in documents:
    list_of_words = [i.lower() for i in wordpunct_tokenize(doc) if i.lower() not in stop_words]

Notice that due to the fact that here you are searching in a set (not in a list) the speed would be theoretically len(stop_words)/2 times faster, which is significant if you need to operate through many documents.

For 5000 documents of approximately 300 words each the difference is between 1.8 seconds for my example and 20 seconds for @alvas's.

P.S. in most of the cases you need to divide the text into words to perform some other classification tasks for which tf-idf is used. So most probably it would be better to use stemmer as well:

from nltk.stem.porter import PorterStemmer
porter = PorterStemmer()

and to use [porter.stem(i.lower()) for i in wordpunct_tokenize(doc) if i.lower() not in stop_words] inside of a loop.

I use ui-grid - v3.0.0-rc.20 because a scrolling issue is fixed when you go full height of container. Use the ui.grid.autoResize module will dynamically auto resize the grid to fit your data. To calculate the height of your grid use the function below. The ui-if is optional to wait until your data is set before rendering.

angular.module('app',['ui.grid','ui.grid.autoResize']).controller('AppController', ['uiGridConstants', function(uiGridConstants) {_x000D_
    ..._x000D_
    _x000D_
    $scope.gridData = {_x000D_
      rowHeight: 30, // set row height, this is default size_x000D_
      ..._x000D_
    };_x000D_
  _x000D_
    ..._x000D_
_x000D_
    $scope.getTableHeight = function() {_x000D_
       var rowHeight = 30; // your row height_x000D_
       var headerHeight = 30; // your header height_x000D_
       return {_x000D_
          height: ($scope.gridData.data.length * rowHeight + headerHeight) + "px"_x000D_
       };_x000D_
    };_x000D_
      _x000D_
    ...

<div ui-if="gridData.data.length>0" id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize ng-style="getTableHeight()"></div>

Simplest Understanding for default export is

Export is ES6's feature which is used to Export a module(file) and use it in some other module(file).

Default Export:

1. default export is the convention if you want to export only one object(variable, function, class) from the file(module).
2. There could be only one default export per file, but not restricted to only one export.
3. When importing default exported object we can rename it as well.

Export or Named Export:

1. It is used to export the object(variable, function, calss) with the same name.

2. It is used to export multiple objects from one file.

3. It cannot be renamed when importing in another file, it must have the same name that was used to export it, but we can create its alias by using as operator.

In React, Vue and many other frameworks the Export is mostly used to export reusable components to make modular based applications.

May be you have ftped the file in ascii mode instead of binary mode ? If not, this might help.

$ gunzip myarchive.tar.gz

And then untar the resulting tar file using

$ tar xvf myarchive.tar

Hope this helps.

React provides an interface for what you are trying to do via the ref attribute. Assign a component a ref, and its current attribute will be your custom component:

class Parent extends React.Class {
    constructor(props) {
        this._child = React.createRef();
    }

    componentDidMount() {
        console.log(this._child.current.someMethod()); // Prints 'bar'
    }

    render() {
        return (
            <div>
                <Child ref={this._child} />
            </div>
        );
    }
}

Note: This will only work if the child component is declared as a class, as per documentation found here: https://facebook.github.io/react/docs/refs-and-the-dom.html#adding-a-ref-to-a-class-component

Update 2019-04-01: Changed example to use a class and createRef per latest React docs.

Update 2016-09-19: Changed example to use ref callback per guidance from the ref String attribute docs.

 protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            //foreach (var relationship in modelBuilder.Model.GetEntityTypes().SelectMany(e => e.GetForeignKeys()))
            //    relationship.DeleteBehavior = DeleteBehavior.Restrict;

            modelBuilder.Entity<User>().ToTable("Users");

            modelBuilder.Entity<IdentityRole<string>>().ToTable("Roles");
            modelBuilder.Entity<IdentityUserToken<string>>().ToTable("UserTokens");
            modelBuilder.Entity<IdentityUserClaim<string>>().ToTable("UserClaims");
            modelBuilder.Entity<IdentityUserLogin<string>>().ToTable("UserLogins");
            modelBuilder.Entity<IdentityRoleClaim<string>>().ToTable("RoleClaims");
            modelBuilder.Entity<IdentityUserRole<string>>().ToTable("UserRoles");

        }
    }

As stated above there is no boolean class just TrueClass and FalseClass however you can use any object as the subject of if/unless and everything is true except instances of FalseClass and nil

Boolean tests return an instance of the FalseClass or TrueClass

(1 > 0).class #TrueClass

The following monkeypatch to Object will tell you whether something is an instance of TrueClass or FalseClass

class Object
  def boolean?
    self.is_a?(TrueClass) || self.is_a?(FalseClass) 
  end
end

Running some tests with irb gives the following results

?> "String".boolean?
=> false
>> 1.boolean?
=> false
>> Time.now.boolean?
=> false
>> nil.boolean?
=> false
>> true.boolean?
=> true
>> false.boolean?
=> true
>> (1 ==1).boolean?
=> true
>> (1 ==2).boolean?
=> true

Here is the short answer:

$ ls -ld directory

Here's what it does:

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

You might be interested in manpages. That's where all people in here get their nice answers from.

refer to online man pages

You're right that it involves a loop, but this is, at least, made simple by use of the each() method:

$('.target').each(
    function(){
        // iterate through each of the `.target` elements, and do stuff in here
        // `this` and `$(this)` refer to the current `.target` element
        var images = $(this).find('img'),
            imageWidth = images.width(); // returns the width of the _first_ image
            numImages = images.length;
        $(this).css('width', (imageWidth*numImages));

    });

• each().
• find().

These are all good ideas in theory, until you go deep. The problem is you can't throttle an RAF without de-synchronizing it, defeating it's very purpose for existing. So you let it run at full-speed, and update your data in a separate loop, or even a separate thread!

Yes, I said it. You can do multi-threaded JavaScript in the browser!

There are two methods I know that work extremely well without jank, using far less juice and creating less heat. Accurate human-scale timing and machine efficiency are the net result.

Apologies if this is a little wordy, but here goes...

Method 1: Update data via setInterval, and graphics via RAF.

Use a separate setInterval for updating translation and rotation values, physics, collisions, etc. Keep those values in an object for each animated element. Assign the transform string to a variable in the object each setInterval 'frame'. Keep these objects in an array. Set your interval to your desired fps in ms: ms=(1000/fps). This keeps a steady clock that allows the same fps on any device, regardless of RAF speed. Do not assign the transforms to the elements here!

In a requestAnimationFrame loop, iterate through your array with an old-school for loop-- do not use the newer forms here, they are slow!

for(var i=0; i<sprite.length-1; i++){  rafUpdate(sprite[i]);  }

In your rafUpdate function, get the transform string from your js object in the array, and its elements id. You should already have your 'sprite' elements attached to a variable or easily accessible through other means so you don't lose time 'get'-ing them in the RAF. Keeping them in an object named after their html id's works pretty good. Set that part up before it even goes into your SI or RAF.

Use the RAF to update your transforms only, use only 3D transforms (even for 2d), and set css "will-change: transform;" on elements that will change. This keeps your transforms synced to the native refresh rate as much as possible, kicks in the GPU, and tells the browser where to concentrate most.

So you should have something like this pseudocode...

// refs to elements to be transformed, kept in an array
var element = [
   mario: document.getElementById('mario'),
   luigi: document.getElementById('luigi')
   //...etc.
]

var sprite = [  // read/write this with SI.  read-only from RAF
   mario: { id: mario  ....physics data, id, and updated transform string (from SI) here  },
   luigi: {  id: luigi  .....same  }
   //...and so forth
] // also kept in an array (for efficient iteration)

//update one sprite js object
//data manipulation, CPU tasks for each sprite object
//(physics, collisions, and transform-string updates here.)
//pass the object (by reference).
var SIupdate = function(object){
  // get pos/rot and update with movement
  object.pos.x += object.mov.pos.x;  // example, motion along x axis
  // and so on for y and z movement
  // and xyz rotational motion, scripted scaling etc

  // build transform string ie
  object.transform =
   'translate3d('+
     object.pos.x+','+
     object.pos.y+','+
     object.pos.z+
   ') '+

   // assign rotations, order depends on purpose and set-up. 
   'rotationZ('+object.rot.z+') '+
   'rotationY('+object.rot.y+') '+
   'rotationX('+object.rot.x+') '+

   'scale3d('.... if desired
  ;  //...etc.  include 
}


var fps = 30; //desired controlled frame-rate


// CPU TASKS - SI psuedo-frame data manipulation
setInterval(function(){
  // update each objects data
  for(var i=0; i<sprite.length-1; i++){  SIupdate(sprite[i]);  }
},1000/fps); //  note ms = 1000/fps


// GPU TASKS - RAF callback, real frame graphics updates only
var rAf = function(){
  // update each objects graphics
  for(var i=0; i<sprite.length-1; i++){  rAF.update(sprite[i])  }
  window.requestAnimationFrame(rAF); // loop
}

// assign new transform to sprite's element, only if it's transform has changed.
rAF.update = function(object){     
  if(object.old_transform !== object.transform){
    element[object.id].style.transform = transform;
    object.old_transform = object.transform;
  }
} 

window.requestAnimationFrame(rAF); // begin RAF

This keeps your updates to the data objects and transform strings synced to desired 'frame' rate in the SI, and the actual transform assignments in the RAF synced to GPU refresh rate. So the actual graphics updates are only in the RAF, but the changes to the data, and building the transform string are in the SI, thus no jankies but 'time' flows at desired frame-rate.

Flow:

[setup js sprite objects and html element object references]

[setup RAF and SI single-object update functions]

[start SI at percieved/ideal frame-rate]
  [iterate through js objects, update data transform string for each]
  [loop back to SI]

[start RAF loop]
  [iterate through js objects, read object's transform string and assign it to it's html element]
  [loop back to RAF]

Method 2. Put the SI in a web-worker. This one is FAAAST and smooth!

Same as method 1, but put the SI in web-worker. It'll run on a totally separate thread then, leaving the page to deal only with the RAF and UI. Pass the sprite array back and forth as a 'transferable object'. This is buko fast. It does not take time to clone or serialize, but it's not like passing by reference in that the reference from the other side is destroyed, so you will need to have both sides pass to the other side, and only update them when present, sort of like passing a note back and forth with your girlfriend in high-school.

Only one can read and write at a time. This is fine so long as they check if it's not undefined to avoid an error. The RAF is FAST and will kick it back immediately, then go through a bunch of GPU frames just checking if it's been sent back yet. The SI in the web-worker will have the sprite array most of the time, and will update positional, movement and physics data, as well as creating the new transform string, then pass it back to the RAF in the page.

This is the fastest way I know to animate elements via script. The two functions will be running as two separate programs, on two separate threads, taking advantage of multi-core CPU's in a way that a single js script does not. Multi-threaded javascript animation.

And it will do so smoothly without jank, but at the actual specified frame-rate, with very little divergence.

Result:

Either of these two methods will ensure your script will run at the same speed on any PC, phone, tablet, etc (within the capabilities of the device and the browser, of course).

I had the same problem when I wrote two upstreams in NGINX conf

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
    server 127.0.0.1:9000;
}

...

fastcgi_pass php_upstream;

but in /etc/php/7.3/fpm/pool.d/www.conf I listened the socket only

listen = /var/run/php/my.site.sock

So I need just socket, no any 127.0.0.1:9000, and I just removed IP+port upstream

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
}

This could be rewritten without an upstream

fastcgi_pass unix:/var/run/php/my.site.sock;

The root cause

In Oracle you have three kinds of SQL statements (and additionally there are PL/SQL blocks):

• Statements in the Data Definiton Language (DDL). These statements modify the structure of the database. They begin usually with the verbs "ALTER" or "CREATE"
• Statements in the Data Modification Langugage (DML). There statements modify the content inside of tables, leaving the structure of each table unmodified. These statements usually begin with "INSERT", "MERGE" or "DELETE".
• Statements in what I call "query language" (there seems to be no canonical name for these). This statements start with the verb "SELECT".

Bind variables in Oracle are only allowed in some special places in DML and query statements. You are trying to use bind variables in a places where they are not allowed. Hence the error.

Solution

Build your statement without bind variables. Build the complete query string instead using string concatenation.

If you want to sanitize the input before concatenating the string, use the DBMS_ASSERT package.

Background

Bind variables can only be used when Oracle can build a query plan without knowing the value of the variable. For DDL statements, there is no query plan. Hence bind variables are not allowed.

In DML and query statements, bind variables are only allowed, when they are used inside a tuple (regarding the underlying set theory), i.e. when the value will be compared with the value in a table or when the value will be inserted in a table. They are not allowed to change the structure of the execution plan (e.g. to change the target table or to change the number of comparisons).

Since you want to design an API using the REST architectural style you need to think about your use cases to decide which concepts are important enough to expose as resources. Should you decide to expose the status of a group as a sub-resource you could give it the following URI and implement support for both GET and PUT methods:

/groups/api/groups/{group id}/status

The downside of this approach over PATCH for modification is that you will not be able to make changes to more than one property of a group atomically and transactionally. If transactional changes are important then use PATCH.

If you do decide to expose the status as a sub-resource of a group it should be a link in the representation of the group. For example if the agent gets group 123 and accepts XML the response body could contain:

<group id="123">
  <status>Active</status>
  <link rel="/linkrels/groups/status" uri="/groups/api/groups/123/status"/>
  ...
</group>

A hyperlink is needed to fulfill the hypermedia as the engine of application state condition of the REST architectural style.

You are facing issue in

 s1.name="Paolo";

because, in the LHS, you're using an array type, which is not assignable.

To elaborate, from C11, chapter §6.5.16

assignment operator shall have a modifiable lvalue as its left operand.

and, regarding the modifiable lvalue, from chapter §6.3.2.1

A modifiable lvalue is an lvalue that does not have array type, [...]

You need to use strcpy() to copy into the array.

That said, data s1 = {"Paolo", "Rossi", 19}; works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9

Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]

download your desired version of php binary from http://windows.php.net/download/ website. download Thread Safe binary zip version. Unzip the downloaded version of the PHP in a separate folder. Please make sure that your new php folder name is not "PHP". May be you can use filder name as the version name. For example for php 5.4 you can use php54.

Copy the new php folder into your xampp folder. Now go to yourxampp/apache/conf/extra folder. Open file httpd-xampp.conf from the folder extra. Change the following variables:

Variable PHPINIDir to be / Varaible LoadModule to be //php5apache2_2.dl

Save the file httpd-xampp.conf. Restart your XAMPP apache server. If your server get restarted successfully then your server php version is upgraded.

I have 2 accounts on my windows machine and I was experiencing this problem with one of them. I did not want to use the sa account, I wanted to use Windows login. It was not immediately obvious to me that I needed to simply sign into the other account that I used to install SQL Server, and add the permissions for the new account from there

(SSMS > Security > Logins > Add a login there)

Easy way to get the full domain name you need to add there open cmd echo each one.

echo %userdomain%\%username%

Add a login for that user and give it all the permissons for master db and other databases you want. When I say "all permissions" make sure NOT to check of any of the "deny" permissions since that will do the opposite.

Drop database exist in all versions of MySQL. But if you want to keep the table structure, here is an idea

mysqldump --no-data --add-drop-database --add-drop-table -hHOSTNAME -uUSERNAME -p > dump.sql

This is a program, not a mysql command

Then, log into mysql and

source dump.sql;

Use String.Trim method.

If you want to select the type of console, you can write this in the file "keybinding.json" (this file can be found in the following path "File-> Preferences-> Keyboard Shortcuts") `

//with this you can select what type of console you want
{
    "key": "ctrl+shift+t",
    "command": "shellLauncher.launch"
},

//and this will help you quickly change console
{ 
    "key": "ctrl+shift+j", 
    "command": "workbench.action.terminal.focusNext" 
},
{
    "key": "ctrl+shift+k", 
    "command": "workbench.action.terminal.focusPrevious" 
}`

Let us say if you want to clear the fields and except accountType,in the mean time dropdown box will be reset to particular value,i.e 'All'.Remaining fields should be reset to empty i.e text box.This approach will be used for clearing particular fields as our requirement.

 $(':input').not('#accountType').each( function() {

    if(this.type=='text' || this.type=='textarea'){
             this.value = '';
       }
    else if(this.type=='radio' || this.type=='checkbox'){
         this.checked=false;
      }
         else if(this.type=='select-one' || this.type=='select-multiple'){
              this.value ='All';
     }
 });

I would say the most elegant way is this:

<div class="toggle"></div>
<div class="content">...</div>

then css:

.toggle{
 display:inline-block;
height:48px;
width:48px;  background:url("http://icons.iconarchive.com/icons/pixelmixer/basic/48/plus-icon.png");
}
.toggle.expanded{
  background:url("http://cdn2.iconfinder.com/data/icons/onebit/PNG/onebit_32.png");
}

and js:

$(document).ready(function(){
  var $content = $(".content").hide();
  $(".toggle").on("click", function(e){
    $(this).toggleClass("expanded");
    $content.slideToggle();
  });
});

FIDDLE

If using the .NET 2.0 (or later) framework you can use the CopyFromScreen() method detailed here:

http://www.geekpedia.com/tutorial181_Capturing-screenshots-using-Csharp.html

//Create a new bitmap.
var bmpScreenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width,
                               Screen.PrimaryScreen.Bounds.Height,
                               PixelFormat.Format32bppArgb);

// Create a graphics object from the bitmap.
var gfxScreenshot = Graphics.FromImage(bmpScreenshot);

// Take the screenshot from the upper left corner to the right bottom corner.
gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                            Screen.PrimaryScreen.Bounds.Y,
                            0,
                            0,
                            Screen.PrimaryScreen.Bounds.Size,
                            CopyPixelOperation.SourceCopy);

// Save the screenshot to the specified path that the user has chosen.
bmpScreenshot.Save("Screenshot.png", ImageFormat.Png);

How about...

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy"];

//Optionally for time zone conversions
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"..."]];

NSString *stringFromDate = [formatter stringFromDate:myNSDateInstance];

//unless ARC is active
[formatter release];

Swift 4.2 :

func stringFromDate(_ date: Date) -> String {
    let formatter = DateFormatter()
    formatter.dateFormat = "dd MMM yyyy HH:mm" //yyyy
    return formatter.string(from: date)
}

Do C-b, :show which will show you all your current settings. /green, nnn will find you which properties have been set to green, the default. Do C-b, :set window-status-bg cyan and the bottom bar should change colour.

List available colours for tmux

You can tell more easily by the titles and the colours as they're actually set in your live session :show, than by searching through the man page, in my opinion. It is a very well-written man page when you have the time though.

If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf with a line like set window-status-bg -g cyan. Here's mine: https://gist.github.com/9083598

I came across this post and went back to an approach that I used some time ago which is similar to @MadAntrax's.

The main difference is that it uses a VBScript user-defined class to wrap all the logic for switching to CScript and outputting text to the console, so it makes the main script a bit cleaner.

This assumes that your objective is to stream output to the console, rather than having output go to message boxes.

The cCONSOLE class is below. To use it, include the complete class at the end of your script, and then instantiate it right at the beginning of the script. Here is an example:

    Option Explicit

'// Instantiate the console object, this automatically switches to CSCript if required
Dim CONS: Set CONS = New cCONSOLE

'// Now we can use the Consol object to write to and read from the console
With CONS

    '// Simply write a line
     .print "CSCRIPT Console demo script"

     '// Arguments are passed through correctly, if present
     .Print "Arg count=" & wscript.arguments.count

     '// List all the arguments on the console log
     dim ix
     for ix = 0 to wscript.arguments.count -1
        .print "Arg(" & ix & ")=" & wscript.arguments(ix)
     next

     '// Prompt for some text from the user
     dim sMsg : sMsg = .prompt( "Enter any text:" )

     '// Write out the text in a box
     .Box sMsg

     '// Pause with the message "Hit enter to continue"
     .Pause

End With

The Dev Tools in Edge finally added support for managing and browsing cookies.

Note: Even if you are testing and supporting IE targets, you mine as well do the heavy lifting of your browser compatibility testing by leveraging the new tooling in Edge, and defer checking in IE 11 (etc) for the last leg.
