There is an Excel file with regexps here. You can easily "convert" it to XML and you will be able to determine country by the full phone number.
UPD: The file that I referenced 4 years ago is no longer accessible. I would recommend using Google's libphonenumber.
The answer to Extract code country from phone number [libphonenumber] will show you the proper way to receive country code from a phone number.
Here's the cleaner and working version of the accepted answer using guzzle:
You can use curl instead of guzzle it's just a simple get request.

Posting a new answer since it is (almost) 2020.
The Android Emulator still only supports HAXM or WHPX on windows. And you may even call it a day already with the latter.
But if you don't like it, there is now work in progress AMD-V support for the former by one of the PS4 emulator developers: https://github.com/jarveson/haxm/tree/svm
This is a limit of the C++ compiler. If you put the function in the header, all the cpp files where it can be inlined can see the "source" of your function and the inlining can be done by the compiler. Otherwhise the inlining would have to be done by the linker (each cpp file is compiled in an obj file separately). The problem is that it would be much more difficult to do it in the linker. A similar problem exists with "template" classes/functions. They need to be instantiated by the compiler, because the linker would have problem instantiating (creating a specialized version of) them. Some newer compiler/linker can do a "two pass" compilation/linking where the compiler does a first pass, then the linker does its work and call the compiler to resolve unresolved things (inline/templates...)
The other answers to this question seem to hit it spot on. Now how would you figure this out for yourself without stack overflow? Check out IPython, an interactive Python shell that has tab auto-complete.
> ipython
import Python 2.5 (r25:51908, Nov 6 2007, 16:54:01)

press tab a few times and you'll be prompted with the members of the "now" object:

now.__getattribute__ now.__new__ now.__str__ now.dst now.max now.resolution now.today now.utctimetuple
and you'll see that now.year is a member of the "now" object.
I like RDC's response, but why limit the JSON returned to have only arrays at the top level? I needed to allow a dictionary at the top level, so I modified it thus:
extension String
{
var parseJSONString: AnyObject?
{
let data = self.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
if let jsonData = data
{
// Will return an object or nil if JSON decoding fails
do
{
let message = try NSJSONSerialization.JSONObjectWithData(jsonData, options:.MutableContainers)
if let jsonResult = message as? NSMutableArray {
return jsonResult //Will return the json array output
} else if let jsonResult = message as? NSMutableDictionary {
return jsonResult //Will return the json dictionary output
} else {
return nil
}
}
catch let error as NSError
{
print("An error occurred: \(error)")
return nil
}
}
else
{
// Lossless conversion of the string was not possible
return nil
}
}

Removing an Environment
Removing a virtual environment is simply done by deactivating it and deleting the environment folder with all its contents:
(ENV)$ deactivate $ rm -r /path/to/ENV
If you're getting source in Content Use the following method
try
{
var response = restClient.Execute<List<EmpModel>>(restRequest);
var jsonContent = response.Content;
var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);
foreach (EmpModel item in data)
{

}
}
catch (Exception ex)
{
Console.WriteLine($"Data get mathod problem {ex} ");
}
I came across a similar problem (wanting to pull a commit that included some binary files which caused conflicts when merged), but came across a different solution that can be done entirely using git (i.e. not having to manually copy files over). I figured I'd include it here so at the very least I can remember it the next time I need it. :) The steps look like this:
% git fetch
This fetches the latest commit(s) from the remote repository (you may need to specify a remote branch name, depending on your setup), but doesn't try to merge them. It records the the commit in FETCH_HEAD
% git checkout FETCH_HEAD stuff/to/update
This takes the copy of the binary files I want and overwrites what's in the working tree with the version fetched from the remote branch. git doesn't try to do any merging, so you just end up with an exact copy of the binary file from the remote branch. Once that's done, you can add/commit the new copy just like normal.
As of currently (September 2014) I would recommend using NSInteger/CGFloat
when interacting with iOS API's etc if you are also building your app for arm64.
This is because you will likely get unexpected results when you use the float
, long
and int
types.
EXAMPLE: FLOAT/DOUBLE vs CGFLOAT
As an example we take the UITableView delegate method tableView:heightForRowAtIndexPath:
.
In a 32-bit only application it will work fine if it is written like this:
-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 44;
}
float
is a 32-bit value and the 44 you are returning is a 32-bit value.
However, if we compile/run this same piece of code in a 64-bit arm64 architecture the 44 will be a 64-bit value. Returning a 64-bit value when a 32-bit value is expected will give an unexpected row height.
You can solve this issue by using the CGFloat
type
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 44;
}
This type represents a 32-bit float
in a 32-bit environment and a 64-bit double
in a 64-bit environment. Therefore when using this type the method will always receive the expected type regardless of compile/runtime environment.
The same is true for methods that expect integers.
Such methods will expect a 32-bit int
value in a 32-bit environment and a 64-bit long
in a 64-bit environment. You can solve this case by using the type NSInteger
which serves as an int
or a long
based on the compile/runtime environemnt.
You can temporarily increase the cache size and do one dummy select and then reset the cache size back to 1. So for example
ALTER SEQUENCE mysequence INCREMENT BY 100;
select mysequence.nextval from dual;
ALTER SEQUENCE mysequence INCREMENT BY 1;
You can create a new table using the following code.
SELECT IDENTITY (int, 1, 1) AS id, column1, column2
INTO dbo.NewTable
FROM dbo.OldTable
Then delete the old db, and rename the new db to the old db's name. Note: that column1 and column2 represent all the columns in your old table that you want to keep in your new table.
There is a very nice workaround using Range.createContextualFragment
.
/**
* Like React's dangerouslySetInnerHTML, but also with JS evaluation.
* Usage:
* <div ref={setDangerousHtml.bind(null, html)}/>
*/
function setDangerousHtml(html, el) {
if(el === null) return;
const range = document.createRange();
range.selectNodeContents(el);
range.deleteContents();
el.appendChild(range.createContextualFragment(html));
}
This works for arbitrary HTML and also retains context information such as document.currentScript
.
Just to add to the choices, there's also XPath. XPath 3.1 handles JSON as well as XML. In XPath 3.1 your required query is ?0?Objects?*[?id=3]
I think using multiple Jframe
s is not a good idea.
Instead we can use JPanel
s more than one or more JPanel
in the same JFrame
.
Also we can switch between this JPanel
s. So it gives us freedom to display more than on thing in the JFrame
.
For each JPanel
we can design different things and all this JPanel
can be displayed on the single JFrame
one at a time.
To switch between this JPanel
s use JMenuBar
with JMenuItems
for each JPanel
or 'JButtonfor each
JPanel`.
More than one JFrame
is not a good practice, but there is nothing wrong if we want more than one JFrame
.
But its better to change one JFrame
for our different needs rather than having multiple JFrame
s.
Can use static block for initialization:
private static Set<Integer> codes1=
new HashSet<Integer>(Arrays.asList(1, 2, 3, 4));
private static Set<Integer> codes2 =
new HashSet<Integer>(Arrays.asList(5, 6, 7, 8));
private static Set<Integer> h = new HashSet<Integer>();
static{
h.add(codes1);
h.add(codes2);
}
Alternatively (just for comparison), if you have Rails installed (actually just ActiveSupport):
require 'activesupport'
array.sum
a['Names'].str.contains('Mel')
will return an indicator vector of boolean values of size len(BabyDataSet)
Therefore, you can use
mel_count=a['Names'].str.contains('Mel').sum()
if mel_count>0:
print ("There are {m} Mels".format(m=mel_count))
Or any()
, if you don't care how many records match your query
if a['Names'].str.contains('Mel').any():
print ("Mel is there")
I love 10 ways to format time and date using JavaScript and Working with Dates.
Basically, you have three methods and you have to combine the strings for yourself:
getDate() // Returns the date
getMonth() // Returns the month
getFullYear() // Returns the year
Example:
var d = new Date();_x000D_
var curr_date = d.getDate();_x000D_
var curr_month = d.getMonth() + 1; //Months are zero based_x000D_
var curr_year = d.getFullYear();_x000D_
console.log(curr_date + "-" + curr_month + "-" + curr_year);
_x000D_
In swift 4.2 I used following code to show and hide code using NSNotification
@objc func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo? [UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
let keyboardheight = keyboardSize.height
print(keyboardheight)
}
}
Try
td.description {_x000D_
line-height: 15px_x000D_
}
_x000D_
<td class="description">Description</td>
_x000D_
Set the line-height value to the desired value.
Check for the value of the parameter:
// .NET < 4.0
if (string.IsNullOrEmpty(Request.QueryString["aspxerrorpath"]))
{
// not there!
}
// .NET >= 4.0
if (string.IsNullOrWhiteSpace(Request.QueryString["aspxerrorpath"]))
{
// not there!
}
If it does not exist, the value will be null
, if it does exist, but has no value set it will be an empty string.
I believe the above will suit your needs better than just a test for null
, as an empty string is just as bad for your specific situation.
function removeParam(parameter)
{
var url=document.location.href;
var urlparts= url.split('?');
if (urlparts.length>=2)
{
var urlBase=urlparts.shift();
var queryString=urlparts.join("?");
var prefix = encodeURIComponent(parameter)+'=';
var pars = queryString.split(/[&;]/g);
for (var i= pars.length; i-->0;)
if (pars[i].lastIndexOf(prefix, 0)!==-1)
pars.splice(i, 1);
url = urlBase+'?'+pars.join('&');
window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .
}
return url;
}
This will resolve your problem
You are creating an array of null references. You should do something like:
for (int i = 0; i < houses.Count; i++)
{
houses[i] = new GameObject();
}
Neither.
Django is a framework, not a language. Python is the language in which Django is written.
Django is a collection of Python libs allowing you to quickly and efficiently create a quality Web application, and is suitable for both frontend and backend.
However, Django is pretty famous for its "Django admin", an auto generated backend that allows you to manage your website in a blink for a lot of simple use cases without having to code much.
More precisely, for the front end, Django helps you with data selection, formatting, and display. It features URL management, a templating language, authentication mechanisms, cache hooks, and various navigation tools such as paginators.
For the backend, Django comes with an ORM that lets you manipulate your data source with ease, forms (an HTML independent implementation) to process user input and validate data and signals, and an implementation of the observer pattern. Plus a tons of use-case specific nifty little tools.
For the rest of the backend work Django doesn't help with, you just use regular Python. Business logic is a pretty broad term.
You probably want to know as well that Django comes with the concept of apps, a self contained pluggable Django library that solves a problem. The Django community is huge, and so there are numerous apps that do specific business logic that vanilla Django doesn't.
You could find the difference between dates in columns in a data frame by using the function difftime
as follows:
df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))
There is no need to create a Java project and let unnecessary Java dependencies and libraries to cling into the project. The question is regarding importing an existing directory into eclipse
Suppose the directory is present in C:/harley/mydir. What you have to do is the following:
Create a new project (Right click on Project explorer, select New -> Project; from the wizard list, select General -> Project and click next.)
Give to the project the same name of your target directory (in this case mydir)
Uncheck Use default location and give the exact location, for example C:/harley/mydir
Click on Finish
You are done. I do it this way.
Use global
keyword:
#Creating global variable
glob_var=0
def use():
#Accessing global variable
global glob_var
#Changing value of global variable
glob_var=2
def show():
#Showing value of global variable
print(glob_var)
if __name__=='__main__':
use()
show()
Agree with Nick. Here is more elaborated code.
#count=0
for idx, item in enumerate(list):
print item
#count +=1
#if count % 10 == 0:
if (idx+1) % 10 == 0:
print 'did ten'
I have commented out the count variable in your code.
Here is sample usage using expect
:
#!/usr/bin/expect
set timeout 360
spawn my_command # Replace with your command.
expect "Do you want to continue?" { send "\r" }
Check: man expect
for further information.
With openpyxl
version 2.4.0
and pandas
version 0.19.2
, the process @ski came up with gets a bit simpler:
import pandas
from openpyxl import load_workbook
with pandas.ExcelWriter('Masterfile.xlsx', engine='openpyxl') as writer:
writer.book = load_workbook('Masterfile.xlsx')
data_filtered.to_excel(writer, "Main", cols=['Diff1', 'Diff2'])
#That's it!
In case of big projects, many files to change and also if the previous project version of PHP was 5.6 and the new one is 7.1, you can create a new file sql.php and include it in the header or somewhere you use it all the time and needs sql connection. For example:
//local
$sql_host = "localhost";
$sql_username = "root";
$sql_password = "";
$sql_database = "db";
$mysqli = new mysqli($sql_host , $sql_username , $sql_password , $sql_database );
/* check connection */
if ($mysqli->connect_errno) {
printf("Connect failed: %s\n", $mysqli->connect_error);
exit();
}
// /* change character set to utf8 */
if (!$mysqli->set_charset("utf8")) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
exit();
} else {
// printf("Current character set: %s\n", $mysqli->character_set_name());
}
if (!function_exists('mysql_real_escape_string')) {
function mysql_real_escape_string($string){
global $mysqli;
if($string){
// $mysqli = new mysqli($sql_host , $sql_username , $sql_password , $sql_database );
$newString = $mysqli->real_escape_string($string);
return $newString;
}
}
}
// $mysqli->close();
$conn = null;
if (!function_exists('mysql_query')) {
function mysql_query($query) {
global $mysqli;
// echo "DAAAAA";
if($query) {
$result = $mysqli->query($query);
return $result;
}
}
}
else {
$conn=mysql_connect($sql_host,$sql_username, $sql_password);
mysql_set_charset("utf8", $conn);
mysql_select_db($sql_database);
}
if (!function_exists('mysql_fetch_array')) {
function mysql_fetch_array($result){
if($result){
$row = $result->fetch_assoc();
return $row;
}
}
}
if (!function_exists('mysql_num_rows')) {
function mysql_num_rows($result){
if($result){
$row_cnt = $result->num_rows;;
return $row_cnt;
}
}
}
if (!function_exists('mysql_free_result')) {
function mysql_free_result($result){
if($result){
global $mysqli;
$result->free();
}
}
}
if (!function_exists('mysql_data_seek')) {
function mysql_data_seek($result, $offset){
if($result){
global $mysqli;
return $result->data_seek($offset);
}
}
}
if (!function_exists('mysql_close')) {
function mysql_close(){
global $mysqli;
return $mysqli->close();
}
}
if (!function_exists('mysql_insert_id')) {
function mysql_insert_id(){
global $mysqli;
$lastInsertId = $mysqli->insert_id;
return $lastInsertId;
}
}
if (!function_exists('mysql_error')) {
function mysql_error(){
global $mysqli;
$error = $mysqli->error;
return $error;
}
}
You can use LambdaEqualityComparer:
var distinctValues
= myCustomerList.Distinct(new LambdaEqualityComparer<OurType>((c1, c2) => c1.CustomerId == c2.CustomerId));
public class LambdaEqualityComparer<T> : IEqualityComparer<T>
{
public LambdaEqualityComparer(Func<T, T, bool> equalsFunction)
{
_equalsFunction = equalsFunction;
}
public bool Equals(T x, T y)
{
return _equalsFunction(x, y);
}
public int GetHashCode(T obj)
{
return obj.GetHashCode();
}
private readonly Func<T, T, bool> _equalsFunction;
}
I was facing the same error. The solution that worked for me is:
From the server end, while returning JSON response, change the content-type: text/html
Now the browsers (Chrome, Firefox and IE8) do not give an error.
The completion of a CSS Transition generates a corresponding DOM Event. An event is fired for each property that undergoes a transition. This allows a content developer to perform actions that synchronize with the completion of a transition.
To determine when a transition completes, set a JavaScript event listener function for the DOM event that is sent at the end of a transition. The event is an instance of WebKitTransitionEvent, and its type is
webkitTransitionEnd
.
box.addEventListener( 'webkitTransitionEnd',
function( event ) { alert( "Finished transition!" ); }, false );
There is a single event that is fired when transitions complete. In Firefox, the event is
transitionend
, in Opera,oTransitionEnd
, and in WebKit it iswebkitTransitionEnd
.
There is one type of transition event available. The
oTransitionEnd
event occurs at the completion of the transition.
The
transitionend
event occurs at the completion of the transition. If the transition is removed before completion, the event will not fire.
Stack Overflow: How do I normalize CSS3 Transition functions across browsers?
Those classes are common extension points for Java UI designs. First off, realize that they don't necessarily have much to do with each other directly, so trying to find a relationship between them might be counterproductive.
JApplet - A base class that let's you write code that will run within the context of a browser, like for an interactive web page. This is cool and all but it brings limitations which is the price for it playing nice in the real world. Normally JApplet is used when you want to have your own UI in a web page. I've always wondered why people don't take advantage of applets to store state for a session so no database or cookies are needed.
JComponent - A base class for objects which intend to interact with Swing.
JFrame - Used to represent the stuff a window should have. This includes borders (resizeable y/n?), titlebar (App name or other message), controls (minimize/maximize allowed?), and event handlers for various system events like 'window close' (permit app to exit yet?).
JPanel - Generic class used to gather other elements together. This is more important with working with the visual layout or one of the provided layout managers e.g. gridbaglayout, etc. For example, you have a textbox that is bigger then the area you have reserved. Put the textbox in a scrolling pane and put that pane into a JPanel. Then when you place the JPanel, it will be more manageable in terms of layout.
In my opinion, uniqueidentifier
/ GUID is neither a varchar
nor an nvarchar
but a char(36)
. Therefore I use:
CAST(xyz AS char(36))
In my case (and probably in all cases), this error resulted from having multiple AWS accounts. So, AWS ECR is not using the right aws credentials assosciated with the aws account.
I tried multiple solutions mentioned here, but did not succeed. It worked after using tokens instead of username and password. I got it working following the instructions here. https://btburnett.com/2017/01/docker-login-for-amazon-aws-ecr-using-windows-powershell.html
Generally, just stating the name of file inside the File constructor means that the file is located in the same directory as the java file. However, when using IDEs like NetBeans and Eclipse i.e. not the case you have to save the file in the project folder directory. So I think checking that will solve your problem.
if you want to start application with cmd use this code:
string YourApplicationPath = "C:\\Program Files\\App\\MyApp.exe"
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.WindowStyle = ProcessWindowStyle.Hidden;
processInfo.FileName = "cmd.exe";
processInfo.WorkingDirectory = Path.GetDirectoryName(YourApplicationPath);
processInfo.Arguments = "/c START " + Path.GetFileName(YourApplicationPath);
Process.Start(processInfo);
You are printing the enum object. Use the .value
attribute if you wanted just to print that:
print(D.x.value)
See the Programmatic access to enumeration members and their attributes section:
If you have an enum member and need its name or value:
>>> >>> member = Color.red >>> member.name 'red' >>> member.value 1
You could add a __str__
method to your enum, if all you wanted was to provide a custom string representation:
class D(Enum):
def __str__(self):
return str(self.value)
x = 1
y = 2
Demo:
>>> from enum import Enum
>>> class D(Enum):
... def __str__(self):
... return str(self.value)
... x = 1
... y = 2
...
>>> D.x
<D.x: 1>
>>> print(D.x)
1
Like this:
var myAssembly = System.Reflection.Assembly.GetEntryAssembly();
var myAssemblyLocation = System.IO.Path.GetDirectoryName(a.Location);
var myHtmlPath = Path.Combine(myAssemblyLocation, "my.html");
List.ForEach() is considered to be more functional.
List.ForEach()
says what you want done. foreach(item in list)
also says exactly how you want it done. This leaves List.ForEach
free to change the implementation of the how part in the future. For example, a hypothetical future version of .Net might always run List.ForEach
in parallel, under the assumption that at this point everyone has a number of cpu cores that are generally sitting idle.
On the other hand, foreach (item in list)
gives you a little more control over the loop. For example, you know that the items will be iterated in some kind of sequential order, and you could easily break in the middle if an item meets some condition.
Some more recent remarks on this issue are available here:
[object Object]
is the default toString representation of an object in javascript.
If you want to know the properties of your object, just foreach over it like this:
for(var property in obj) {
alert(property + "=" + obj[property]);
}
In your particular case, you are getting a jQuery object. Try doing this instead:
$('#senddvd').click(function ()
{
alert('hello');
var a=whichIsVisible();
alert(whichIsVisible().attr("id"));
});
This should alert the id of the visible element.
You can do it by using the td's index:
var tdIndex = $td.index() + 1;
var $th = $('#table tr').find('th:nth-child(' + tdIndex + ')');
You have to create an instance of one of the subclasses. Stream
is an abstract class that can't be instantiated directly.
There are a bunch of choices if you look at the bottom of the reference here:
Stream Class | Microsoft Developer Network
The most common probably being FileStream
or MemoryStream
. Basically, you need to decide where you wish the data backing your stream to come from, then create an instance of the appropriate subclass.
Most common case of this error happening is using template that is generating the control then changing the way id
and/or name
are being generated by 'overriding' default template with something like
@Html.TextBoxFor(m => m, new {Name = ViewData["Name"], id = ViewData["UniqueId"]} )
and then forgetting to change ValidationMessageFor

@Html.ValidationMessageFor(m => m, null, new { data_valmsg_for = ViewData["Name"] })
Hope this saves you some time.
With design (based on problem). This is an alternate of divide-and-conquer. We'll first define an enum (considering it's only for an unsigned int).
public enum IntegerLength {
One((byte)1,10),
Two((byte)2,100),
Three((byte)3,1000),
Four((byte)4,10000),
Five((byte)5,100000),
Six((byte)6,1000000),
Seven((byte)7,10000000),
Eight((byte)8,100000000),
Nine((byte)9,1000000000);
byte length;
int value;
IntegerLength(byte len,int value) {
this.length = len;
this.value = value;
}
public byte getLenght() {
return length;
}
public int getValue() {
return value;
}
}
Now we'll define a class that goes through the values of the enum and compare and return the appropriate length.
public class IntegerLenght {
public static byte calculateIntLenght(int num) {
for(IntegerLength v : IntegerLength.values()) {
if(num < v.getValue()){
return v.getLenght();
}
}
return 0;
}
}
The run time of this solution is the same as the divide-and-conquer approach.
isn't it only :order => 'column1 ASC, column2 DESC'
?
you forgot to add add alpha1 in module area
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
use maven repository in project area that's it
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
In your activity declare static variable
public static HashMap<String,ContactsModal> contactItems=new HashMap<String, ContactsModal>();
Then in your fragment do like follow
ActivityName.contactItems.put(Number,contactsModal);
If you want to get an object, using get()
is more straightforward:
obj = Class.objects.get(pk=this_object_id)
You will want to move the loop for the files outside of the loop for the folders. In addition you will need to pass the data structure holding the collection of files to each call of the method. That way all files go into a single list.
public static List<string> DirSearch(string sDir, List<string> files)
{
foreach (string f in Directory.GetFiles(sDir, "*.xml"))
{
string extension = Path.GetExtension(f);
if (extension != null && (extension.Equals(".xml")))
{
files.Add(f);
}
}
foreach (string d in Directory.GetDirectories(sDir))
{
DirSearch(d, files);
}
return files;
}
Then call it like this.
List<string> files = DirSearch("c:\foo", new List<string>());
Update:
Well unbeknownst to me, until I read the other answer anyway, there is already a builtin mechanism for doing this. I will leave my answer in case you are interested in seeing how your code needs to be modified to make it work.
I had to add a user environment variable, HOME
, with C:\Users\<your user name>
by going to System, Advanced System Settings, in the System Properties window, the Advanced tab, Environment Variables...
Then in my C:\Users\<your user name>
I created the file .bashrc
, e.g., touch .bashrc
and added the desired aliases.
to make it as globally reuse function using jquery
HTML
<select class="select_location">
<option value="http://localhost.com/app/page1.html">Page 1</option>
<option value="http://localhost.com/app/page2.html">Page 2</option>
<option value="http://localhost.com/app/page3.html">Page 3</option>
</select>
Javascript using jquery
$('.select_location').on('change', function(){
window.location = $(this).val();
});
now you will able to reuse this function by adding .select_location class to any Select element class
You can repeat your string (in case it's not a single char) and concat the result, like this:
String.Concat(Enumerable.Repeat("---", 5))
Just try like this:
HTML in PHP :
$link_address1 = 'index.php';
echo "<a href='".$link_address1."'>Index Page</a>";
$link_address2 = 'page2.php';
echo "<a href='".$link_address2."'>Page 2</a>";
Easiest way
$link_address1 = 'index.php';
echo "<a href='$link_address1'>Index Page</a>";
$link_address2 = 'page2.php';
echo "<a href='$link_address2'>Page 2</a>";
There is a better why to determine type of an image. with exif_imagetype
If you use this function, you can tell image's real extension.
with this function filename's extension is completely irrelevant, which is good.
function setHeaderContentType(string $filePath): void
{
$numberToContentTypeMap = [
'1' => 'image/gif',
'2' => 'image/jpeg',
'3' => 'image/png',
'6' => 'image/bmp',
'17' => 'image/ico'
];
$contentType = $numberToContentTypeMap[exif_imagetype($filePath)] ?? null;
if ($contentType === null) {
throw new Exception('Unable to determine content type of file.');
}
header("Content-type: $contentType");
}
You can add more types from the link.
Hope it helps.
I would prefer to do this by return. Put the looping part in private function and return when you want to break the loop.
Note: starting git1.8.3.2 (July 2013), the following command (mentioned above by Jeremy W Sherman) won't open an editor anymore:
git commit --allow-empty-message -m ''
See commit 25206778aac776fc6cc4887653fdae476c7a9b5a:
If an empty message is specified with the option
-m
of git commit then the editor is started.
That's unexpected and unnecessary.
Instead of using the length of the message string for checking if the user specified one, directly remember if the option-m
was given.
git 2.9 (June 2016) improves the empty message behavior:
See commit 178e814 (06 Apr 2016) by Adam Dinwoodie (me-and

commit
: do not ignore an empty message given by-m ''
- "
git commit --amend -m '' --allow-empty-message
", even though it looks strange, is a valid request to amend the commit to have no message at all.
Due to the misdetection of the presence of-m
on the command line, we ended up keeping the log messsage from the original commit.- "
git commit -m "$msg" -F file
" should be rejected whether$msg
is an empty string or not, but due to the same bug, was not rejected when$msg
is empty.- "
git -c template=file -m "$msg"
" should ignore the template even when$msg
is empty, but it didn't and instead used the contents from the template file.
you can import django and then type print statement as given below to know the version of django i.e. installed on your system:
>>> import django
>>> print(django.get_version())

The simplest way to do this is like this
index.php
<?php $active = 'home'; include 'second.php'; ?>
second.php
<?php echo $active; ?>
You can share variables since you are including 2 files by using "include"
Extension to parse decimal number from string.
Ability to set decimal symbol manually.
public static class StringExtension
{
public static double DoubleParseAdvanced(this string strToParse, char decimalSymbol = ',')
{
string tmp = Regex.Match(strToParse, @"([-]?[0-9]+)([\s])?([0-9]+)?[." + decimalSymbol + "]?([0-9 ]+)?([0-9]+)?").Value;
if (tmp.Length > 0 && strToParse.Contains(tmp))
{
var currDecSeparator = System.Windows.Forms.Application.CurrentCulture.NumberFormat.NumberDecimalSeparator;
tmp = tmp.Replace(".", currDecSeparator).Replace(decimalSymbol.ToString(), currDecSeparator);
return double.Parse(tmp);
}
return 0;
}
}
How to use:
"It's 4.45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4,45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4:45 O'clock now".DoubleParseAdvanced(':'); // will return 4.45
netstat -ano|grep 443|grep LISTEN
will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).
You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).
This is a good understanding of data-binding. I think you've got that down.
For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.
I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.
I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.
<div rotate-on-click="45"></div>
First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.
function rotate(deg, elem) {
$(elem).css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
}
function addRotateOnClick($elems) {
$elems.each(function(i, elem) {
var deg = 0;
$(elem).click(function() {
deg+= parseInt($(this).attr('rotate-on-click'), 10);
rotate(deg, this);
});
});
}
addRotateOnClick($('[rotate-on-click]'));
app.directive('rotateOnClick', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var deg = 0;
element.bind('click', function() {
deg+= parseInt(attrs.rotateOnClick, 10);
element.css({
webkitTransform: 'rotate('+deg+'deg)',
mozTransform: 'rotate('+deg+'deg)',
msTransform: 'rotate('+deg+'deg)',
oTransform: 'rotate('+deg+'deg)',
transform: 'rotate('+deg+'deg)'
});
});
}
};
});
Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link
function (or compile
function).
Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.
This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?
The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.
Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:
Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.
Here are some things that modern frameworks are providing:
Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.
If you need to destroy a planet and you have a Death Star, use the Death star.
Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.
In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:
<clock></clock>
Done.
Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.
Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.
THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.
Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

When the validation fails return back with the validation errors.
if($validator->fails()) {
return Redirect::back()->withErrors($validator);
}
You can catch the error on your view using
@if($errors->any())
{{ implode('', $errors->all('<div>:message</div>')) }}
@endif
UPDATE
To display error under each field you can do like this.
<input type="text" name="firstname">
@if($errors->has('firstname'))
<div class="error">{{ $errors->first('firstname') }}</div>
@endif
For better display style with css.
You can refer to the docs here.
UPDATE 2
To display all errors at once
@if($errors->any())
{!! implode('', $errors->all('<div>:message</div>')) !!}
@endif
To display error under each field.
@error('firstname')
<div class="error">{{ $message }}</div>
@enderror

$("#myDiv form#myForm").html(chbx);
//to insert dynamically created form
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");
The best solution depends on how much code is incompatible. If there are a lot of places you need to support Python 2 and 3, six
is the compatibility module. six.PY2
and six.PY3
are two booleans if you want to check the version.
However, a better solution than using a lot of if
statements is to use six
compatibility functions if possible. Hypothetically, if Python 3000 has a new syntax for next
, someone could update six
so your old code would still work.
import six
#OK
if six.PY2:
x = it.next() # Python 2 syntax
else:
x = next(it) # Python 3 syntax
#Better
x = six.next(it)

char *strPtr = &str[0]; //declaration and initialization
alternatively, you can split this in two:
char *strPtr; strPtr = &str[0];
strPtr
is a pointer to a char
strPtr

is a variable that stores value of address &str[0]
strPtr
own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])&strPtr
represents the address of strPtr itselfI think that you could declare a pointer to a pointer as:
char **vPtr = &strPtr;
declares and initializes with address of strPtr pointer
Alternatively you could split in two:
char **vPtr;
*vPtr = &strPtr
*vPtr
points at strPtr pointer*vPtr

Thought I would mention this because it took a while for me to fix this issue and I couldn't find the answer anywhere on SO. The code I was working on worked for a co-worker but not for me (I was getting this same error). It worked for me in Chrome, but not in Edge.
I was able to get it working by clearing the cache in Edge.
This may not be the answer to this specific question, but I thought I would mention it in case it saves someone else a little time.
Check you PATH environment variable once. Make sure the correct location of your JDK is specified there.
Try this to check
$('#captureImage').attr("checked",true).checkboxradio("refresh");
and uncheck
$('#captureImage').attr("checked",false).checkboxradio("refresh");
I like this a lot better. reduces the if/switch, just do.
private enum Alignment { LEFT, RIGHT;
void process() {
//Process it...
}
};
String drawCellValue (int maxCellLength, String cellValue, Alignment align){
align.process();
}
of course, it can be:
String process(...) {
//Process it...
}
Where you declare the myclass[] array as :
xClass myclass[] = new xClass[10]
, simply pass in as an argument the number of XClass elements you'll need. At that point do you know how many you will need? By declaring the array as having 10 elements, you are not declaring 10 XClass objects, you're simply creating an array with 10 elements of type xClass.

This example works best for React.
More accurately, your mod1
and lib
directories are not modules, they are packages. The file mod11.py
is a module.
Python does not automatically import subpackages or modules. You have to explicitly do it, or "cheat" by adding import statements in the initializers.
>>> import lib
>>> dir(lib)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
>>> import lib.pkg1
>>> import lib.pkg1.mod11
>>> lib.pkg1.mod11.mod12()
mod12
An alternative is to use the from
syntax to "pull" a module from a package into you scripts namespace.
>>> from lib.pkg1 import mod11
Then reference the function as simply mod11.mod12()
.
Very simple. Just follow these procedure:
1. git status
2. git add {File_Name} //the file name you haven been changed
3. git status
4. git commit -m '{your_message}'
5. git push origin master
Try:
tr -s ' ' <text.txt | cut -d ' ' -f4
From the tr
man page:
-s, --squeeze-repeats replace each input sequence of a repeated character that is listed in SET1 with a single occurrence of that character
I think that this is as easy as I can explain it. Please, anyone is welcome to correct me or add to this.
SOAP is a message format used by disconnected systems (like across the internet) to exchange information / data. It does with XML messages going back and forth.
Web services transmit or receive SOAP messages. They work differently depending on what language they are written in.
dplyr
packageIf the function that you want to apply is vectorized,
then you could use the mutate
function from the dplyr
package:
> library(dplyr)
> myf <- function(tens, ones) { 10 * tens + ones }
> x <- data.frame(hundreds = 7:9, tens = 1:3, ones = 4:6)
> mutate(x, value = myf(tens, ones))
hundreds tens ones value
1 7 1 4 14
2 8 2 5 25
3 9 3 6 36
plyr
packageIn my humble opinion,
the tool best suited to the task is mdply
from the plyr
package.
Example:
> library(plyr)
> x <- data.frame(tens = 1:3, ones = 4:6)
> mdply(x, function(tens, ones) { 10 * tens + ones })
tens ones V1
1 1 4 14
2 2 5 25
3 3 6 36
Unfortunately, as Bertjan Broeksema pointed out,
this approach fails if you don't use all the columns of the data frame
in the mdply
call.
For example,
> library(plyr)
> x <- data.frame(hundreds = 7:9, tens = 1:3, ones = 4:6)
> mdply(x, function(tens, ones) { 10 * tens + ones })
Error in (function (tens, ones) : unused argument (hundreds = 7)
Well, as suggested by Hellfire you can use td
width or you could place an element in the td and adjust its width. We could not use
CSS property Padding
as in Microsoft Outlook
padding does not work.
So what I had to do is,
<table>
<tr>
<td><span style="display: inline-block; width: 40px;"></span><span>Content<span></td>
<td>Content</td>
</tr>
</table>
With this you can adjust right and left spacing. For top and bottom spacing you could use td's height property. Like,
<table>
<tr>
<td style="vertical-align: top; height: 100px;">Content</td>
<td>Content</td>
</tr>
</table>
This will increase bottom space.
Hope it will work for you guys. :)

A missing intermediate certificate might be the problem.
You may want to check your https://hostname with curl, openssl or a website like https://www.digicert.com/help/.
No idea why Chrome (possibly) sometimes has problems validating these certs.
Although I take the risk of not being popular I say they are not useful nowadays.
I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.
Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.
Let's take an example:
On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.
Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.
In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.
Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards

bar2 IN number DEFAULT 5,
bar3 IN number DEFAULT 8 );
if you call this procedure with no arguments then it will behave as if called with
foo( bar1 => 3,
bar2 => 5,
bar3 => 8 );
but 'NULL' is still a parameter.
foo( 4,
bar3 => NULL );
This will then act like
foo( bar1 => 4,
bar2 => 5,
bar3 => Null );
( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )
one way to treat NULL the same as a default value would be to default the value to NULL
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL );
and using a variable with the desired value then
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL )
AS
v_bar1 number := NVL( bar1, 3);
v_bar2 number := NVL( bar2, 5);
v_bar3 number := NVL( bar3, 8);

This is an old question but there is no a clean solution yet. This probably is not answering this specific question, but those looking for answers on 'how to gracefully exit from an R script' will probably land here. It seems that R developers forgot to implement an exit() function. Anyway, the trick I've found is:
continue <- TRUE
tryCatch({
# You do something here that needs to exit gracefully without error.
...
# We now say bye-bye
stop("exit")
}, error = function(e) {
if (e$message != "exit") {
# Your error message goes here. E.g.
stop(e)
}
continue <<-FALSE
})
if (continue) {
# Your code continues here
...
}
cat("done.\n")
Basically, you use a flag to indicate the continuation or not of a specified block of code. Then you use the stop()
function to pass a customized message to the error handler of a tryCatch()
function. If the error handler receives your message to exit gracefully, then it just ignores the error and set the continuation flag to FALSE
.
Here's a list of what "the loggers" have.

Only mozilla implements a simple property in css : http://caniuse.com/#search=scroll-behavior
you will have to use JS at least.
I personally use this because its easy to use (I use JQ but you can adapt it I guess):
/*Scroll transition to anchor*/
$("a.toscroll").on('click',function(e) {
var url = e.target.href;
var hash = url.substring(url.indexOf("#")+1);
$('html, body').animate({
scrollTop: $('#'+hash).offset().top
}, 500);
return false;
});
just add class toscroll to your a tag
Yes - older POSIX standards defined usleep()
, so this is available on Linux:
int usleep(useconds_t usec);
DESCRIPTION
The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers.
usleep()
takes microseconds, so you will have to multiply the input by 1000 in order to sleep in milliseconds.
usleep()
has since been deprecated and subsequently removed from POSIX; for new code, nanosleep()
is preferred:
#include <time.h> int nanosleep(const struct timespec *req, struct timespec *rem);
DESCRIPTION
nanosleep()
suspends the execution of the calling thread until either at least the time specified in*req
has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process.The structure timespec is used to specify intervals of time with nanosecond precision. It is defined as follows:
struct timespec { time_t tv_sec; /* seconds */ long tv_nsec; /* nanoseconds */ };
An example msleep()
function implemented using nanosleep()
, continuing the sleep if it is interrupted by a signal:
#include <time.h>
#include <errno.h>
/* msleep(): Sleep for the requested number of milliseconds. */
int msleep(long msec)
{
struct timespec ts;
int res;
if (msec < 0)
{
errno = EINVAL;
return -1;
}
ts.tv_sec = msec / 1000;
ts.tv_nsec = (msec % 1000) * 1000000;
do {
res = nanosleep(&ts, &ts);
} while (res && errno == EINTR);
return res;
}
It is possible to turn the string into a stream by using the std::stringstream
class (its constructor takes a string as parameter). Once it's built, you can use the >>
operator on it (like on regular file based streams), which will extract, or tokenize word from it:
#include <iostream>
#include <sstream>
using namespace std;
int main(){
string line = "test one two three.";
string arr[4];
int i = 0;
stringstream ssin(line);
while (ssin.good() && i < 4){
ssin >> arr[i];
++i;
}
for(i = 0; i < 4; i++){
cout << arr[i] << endl;
}
}
I wrote up some code that will sort a table by a row, assuming only one <tbody>
and cells don't have a colspan.
function sortTable(table, col, reverse) {
var tb = table.tBodies[0], // use `<tbody>` to ignore `<thead>` and `<tfoot>` rows
tr = Array.prototype.slice.call(tb.rows, 0), // put rows into array
i;
reverse = -((+reverse) || -1);
tr = tr.sort(function (a, b) { // sort rows
return reverse // `-1 *` if want opposite order
* (a.cells[col].textContent.trim() // using `.textContent.trim()` for test
.localeCompare(b.cells[col].textContent.trim())
);
});
for(i = 0; i < tr.length; ++i) tb.appendChild(tr[i]); // append each row in order
}
// sortTable(tableNode, columId, false);
If you don't want to make the assumptions above, you'd need to consider how you want to behave in each circumstance. (e.g. put everything into one <tbody>
or add up all the preceeding colspan values, etc.)
You could then attach this to each of your tables, e.g. assuming titles are in <thead>
function makeSortable(table) {
var th = table.tHead, i;
th && (th = th.rows[0]) && (th = th.cells);
if (th) i = th.length;
else return; // if no `<thead>` then do nothing
while (--i >= 0) (function (i) {
var dir = 1;
th[i].addEventListener('click', function () {sortTable(table, i, (dir = 1 - dir))});
}(i));
}
function makeAllSortable(parent) {
parent = parent || document.body;
var t = parent.getElementsByTagName('table'), i = t.length;
while (--i >= 0) makeSortable(t[i]);
}
and then invoking makeAllSortable
onload.
Example fiddle of it working on a table.
I had the same problem;
textStatus = 'error'
errorThrown = (empty)
xhr.status = 0
That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)
I have tried calling it this way also:
var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});
but without success.
This post solved it for me: jQuery AJAX cross domain

jakub.g's answer is correct, however an example using grunt seems a bit complex.
So my simpler answer:
- Sending a command line argument to an npm script
Syntax for sending command line arguments to an npm script:
npm run [command] [-- <args>]
Imagine we have an npm start task in our package.json to kick off webpack dev server:
"scripts": {
"start": "webpack-dev-server --port 5000"
},
We run this from the command line with npm start
Now if we want to pass in a port to the npm script:
"scripts": {
"start": "webpack-dev-server --port process.env.port || 8080"
},
running this and passing the port e.g. 5000 via command line would be as follows:
npm start --port:5000
- Using package.json config:
As mentioned by jakub.g, you can alternatively set params in the config of your package.json
"config": {
"myPort": "5000"
}
"scripts": {
"start": "webpack-dev-server --port process.env.npm_package_config_myPort || 8080"
},
npm start
will use the port specified in your config, or alternatively you can override it
npm config set myPackage:myPort 3000
- Setting a param in your npm script
An example of reading a variable set in your npm script. In this example NODE_ENV
"scripts": {
"start:prod": "NODE_ENV=prod node server.js",
"start:dev": "NODE_ENV=dev node server.js"
},
read NODE_ENV in server.js either prod or dev
var env = process.env.NODE_ENV || 'prod'
if(env === 'dev'){
var app = require("./serverDev.js");
} else {
var app = require("./serverProd.js");
}
i want to post my solution here which was done AngularJS, ASP.NET MVC. The code illustrates how to download file with authentication.
WebApi method along with helper class:
[RoutePrefix("filess")]
class FileController: ApiController
{
[HttpGet]
[Route("download-file")]
[Authorize(Roles = "admin")]
public HttpResponseMessage DownloadDocument([FromUri] int fileId)
{
var file = "someFile.docx"// asking storage service to get file path with id
return Request.ReturnFile(file);
}
}
static class DownloadFIleFromServerHelper
{
public static HttpResponseMessage ReturnFile(this HttpRequestMessage request, string file)
{
var result = request.CreateResponse(HttpStatusCode.OK);
result.Content = new StreamContent(new FileStream(file, FileMode.Open, FileAccess.Read));
result.Content.Headers.Add("x-filename", Path.GetFileName(file)); // letters of header names will be lowercased anyway in JS.
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = Path.GetFileName(file)
};
return result;
}
}
Web.config file changes to allow sending file name in custom header.
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Methods" value="POST,GET,PUT,PATCH,DELETE,OPTIONS" />
<add name="Access-Control-Allow-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Expose-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Allow-Origin" value="*" />
Angular JS Service Part:
function proposalService($http, $cookies, config, FileSaver) {
return {
downloadDocument: downloadDocument
};
function downloadFile(documentId, errorCallback) {
$http({
url: config.apiUrl + "files/download-file?documentId=" + documentId,
method: "GET",
headers: {
"Content-type": "application/json; charset=utf-8",
"Authorization": "Bearer " + $cookies.get("api_key")
},
responseType: "arraybuffer"
})
.success( function(data, status, headers) {
var filename = headers()['x-filename'];
var blob = new Blob([data], { type: "application/octet-binary" });
FileSaver.saveAs(blob, filename);
})
.error(function(data, status) {
console.log("Request failed with status: " + status);
errorCallback(data, status);
});
};
};
Module dependency for FileUpload: angular-file-download (gulp install angular-file-download --save). Registration looks like below.
var app = angular.module('cool',
[
...
require('angular-file-saver'),
])
. // other staff.
Put into the Button-Control the Attribute "UseSubmitBehavior=false".
Its too late, but it may be simple and useful
var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };
var keytoFind = "key2";
var index = Object.keys(json).indexOf(keytoFind);
alert(index);
tl;dr the "standards" are a hodge-podge mess; it depends who you ask!
Overall, there appears to be no MIME type image/jpg
. Yet, in practice, nearly all software handles image files named "*.jpg
" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg
could be many different things.
For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.
.jfif
, .jfif-tbnl
, .jpe
, .jpeg
, .jpg
? image/jpeg
.jfif
, .jpe
, .jpeg
, .jpg
? image/pjpeg
.jpeg
, .jpg
? image/jpeg
.jpeg
, .jpg
? image/x-citrix-jpeg
.pjpeg
? image/pjpeg
jpg
not mentionedjpeg
? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg
13JPEG
? video/JPEG
jpeg2000
? video/jpeg2000
jpm
? image/jpm
(JPEG 2000)jpx
? image/jpx
(JPEG 2000)vnd.sealedmedia.softseal.jpg
? image/vnd.sealedmedia.softseal.jpg
These "complete lists" and RFC do not have MIME type image/jpg
! But for MIME type image/jpeg
some lists do have varying file name extensions (.jpeg
, .jpg
, …). Other lists do not mention image/jpeg
.
Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.
Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf
is preferred file extension for image/jpx
but in IANA Media Types the name jpf
is not present (and that IANA document references RFC 3745!).
Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.
Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?
The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg
yet there exists the odd vnd.sealedmedia.softseal.jpg
. File extension.JPEG
is only known as a video
type while file extension .jpeg
is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000
is type video
yet RFC 3745 considers JPEG 2000 an image
type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg
).
Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

From Wikipedia,
The Card Security Code is located on the back of MasterCard, Visa and Discover credit or debit cards and is typically a separate group of 3 digits to the right of the signature strip. On American Express cards, the Card Security Code is a printed (NOT embossed) group of four digits on the front towards the right.
The Card Security Code (CSC), sometimes called Card Verification Value (CVV or CV2), Card Verification Value Code (CVVC), Card Verification Code (CVC), Verification Code (V-Code or V Code), or Card Code Verification (CCV)[1] is a security feature for credit or debit card transactions, giving increased protection against credit card fraud.
There are actually several types of security codes:
* The first code, called CVC1 or CVV1, is encoded on the magnetic stripe of the card and used for transactions in person.
* The second code, and the most cited, is CVV2 or CVC2. This CSC (also known as a CCID or Credit Card ID) is often asked for by merchants for them to secure "card not present" transactions occurring over the Internet, by mail, fax or over the phone. In many countries in Western Europe, due to increased attempts at card fraud, it is now mandatory to provide this code when the cardholder is not present in person.
* Contactless Card and Chip cards may supply their own codes generated electronically, such as iCVV or Dynamic CVV.
The CVC should not be confused with the standard card account number appearing in embossed or printed digits. (The standard card number undergoes a separate validation algorithm called the Luhn algorithm which serves to determine whether a given card's number is appropriate.)
The CVC should not be confused with PIN codes such as MasterCard SecureCode or Visa Verified by Visa. These codes are not printed or embedded in the card but are entered at the time of transaction using a keypad.

long strtol (const char *String, char **EndPointer, int Base)
// examples
strtol(s, NULL, 10);
strtol(s, &s, 10);
The conditional operator is great for short conditions, like this:
varA = boolB ? valC : valD;
I use it occasionally because it takes less time to write something that way... unfortunately, this branching can sometimes be missed by another developer browsing over your code. Plus, code isn't usually that short, so I usually help readability by putting the ? and : on separate lines, like this:
doSomeStuffToSomething(shouldSomethingBeDone()
? getTheThingThatNeedsStuffDone()
: getTheOtherThingThatNeedsStuffDone());
However, the big advantage to using if/else blocks (and why I prefer them) is that it's easier to come in later and add some additional logic to the branch,
if (shouldSomethingBeDone()) {
doSomeStuffToSomething(getTheThingThatNeedsStuffDone());
doSomeAdditionalStuff();
} else {
doSomeStuffToSomething(getTheOtherThingThatNeedsStuffDone());
}
or add another condition:
if (shouldSomethingBeDone()) {
doSomeStuffToSomething(getTheThingThatNeedsStuffDone());
doSomeAdditionalStuff();
} else if (shouldThisOtherThingBeDone()){
doSomeStuffToSomething(getTheOtherThingThatNeedsStuffDone());
}
So, in the end, it's about convenience for you now (shorter to use :?) vs. convenience for you (and others) later. It's a judgment call... but like all other code-formatting issues, the only real rule is to be consistent, and be visually courteous to those who have to maintain (or grade!) your code.

You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php
It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.

If you are using any user control and want to get any text box values then you can use the below code:
var result = document.getElementById('LE_OtherCostsDetails_txtHomeOwnerInsurance').value;
Here, LE_OtherCostsDetails
, is the name of the user control and txtHomeOwnerInsurance
is the id of the text box.

What I would suggest is not converting the non-static class to a static class because in that case, your inner class can't access the non-static members of outer class.
Example :
class Outer
{
class Inner
{
//...
}
}
So, in such case, you can do something like:
Outer o = new Outer();
Outer.Inner obj = o.new Inner();
Others pointed out to use SQS and Step Functions. But both these solutions add additional cost. Step Function state transitions are supposedly very expensive.
AWS lambda offers some retry logic. Where it tries something for 3 times. I am not sure if that is still valid when you trigger it use the API.

If you want to allow every bot to crawl everything, this is the best way to specify it in your robots.txt:
User-agent: *
Disallow:
Note that the Disallow
field has an empty value, which means according to the specification:
Any empty value, indicates that all URLs can be retrieved.
Your way (with Allow: /
instead of Disallow:
) works, too, but Allow
is not part of the original robots.txt specification, so it’s not supported by all bots (many popular ones support it, though, like the Googlebot). That said, unrecognized fields have to be ignored, and for bots that don’t recognize Allow
, the result would be the same in this case anyway: if nothing is forbidden to be crawled (with Disallow
), everything is allowed to be crawled.
However, formally (per the original spec) it’s an invalid record, because at least one Disallow
field is required:
At least one Disallow field needs to be present in a record.
Assert.Throws
returns the exception that's thrown which lets you assert on the exception.
var ex = Assert.Throws<Exception>(() => user.MakeUserActive());
Assert.That(ex.Message, Is.EqualTo("Actual exception message"));
So if no exception is thrown, or an exception of the wrong type is thrown, the first Assert.Throws
assertion will fail. However if an exception of the correct type is thrown then you can now assert on the actual exception that you've saved in the variable.
By using this pattern you can assert on other things than the exception message, e.g. in the case of ArgumentException
and derivatives, you can assert that the parameter name is correct:
var ex = Assert.Throws<ArgumentNullException>(() => foo.Bar(null));
Assert.That(ex.ParamName, Is.EqualTo("bar"));
You can also use the fluent API for doing these asserts:
Assert.That(() => foo.Bar(null),
Throws.Exception
.TypeOf<ArgumentNullException>()
.With.Property("ParamName")
.EqualTo("bar"));
or alternatively
Assert.That(
Assert.Throws<ArgumentNullException>(() =>
foo.Bar(null)
.ParamName,
Is.EqualTo("bar"));
A little tip when asserting on exception messages is to decorate the test method with the SetCultureAttribute
to make sure that the thrown message is using the expected culture. This comes into play if you store your exception messages as resources to allow for localization.

dict1={'a':1, 'b':'banana'}
To list the dictionary in Python 2.x:
for k,v in dict1.iteritems():
print k,v
In Python 3.x use:
for k,v in dict1.items():
print(k,v)
# a 1
# b banana
Finally, as others have indicated, if you want a running index, you can have that too:
for i in enumerate(dict1.items()):
print(i)
# (0, ('a', 1))
# (1, ('b', 'banana'))
But this defeats the purpose of a dictionary (map, associative array) , which is an efficient data structure for telephone-book-style look-up. Dictionary ordering could be incidental to the implementation and should not be relied upon. If you need the order, use OrderedDict instead.
As so many others have said, the object assigned to a val
cannot be replaced, and the object assigned to a var
can. However, said object can have its internal state modified. For example:
class A(n: Int) {
var value = n
}
class B(n: Int) {
val value = new A(n)
}
object Test {
def main(args: Array[String]) {
val x = new B(5)
x = new B(6) // Doesn't work, because I can't replace the object created on the line above with this new one.
x.value = new A(6) // Doesn't work, because I can't replace the object assigned to B.value for a new one.
x.value.value = 6 // Works, because A.value can receive a new object.
}
}
So, even though we can't change the object assigned to x
, we could change the state of that object. At the root of it, however, there was a var
.
Now, immutability is a good thing for many reasons. First, if an object doesn't change internal state, you don't have to worry if some other part of your code is changing it. For example:
x = new B(0)
f(x)
if (x.value.value == 0)
println("f didn't do anything to x")
else
println("f did something to x")
This becomes particularly important with multithreaded systems. In a multithreaded system, the following can happen:
x = new B(1)
f(x)
if (x.value.value == 1) {
print(x.value.value) // Can be different than 1!
}
If you use val
exclusively, and only use immutable data structures (that is, avoid arrays, everything in scala.collection.mutable
, etc.), you can rest assured this won't happen. That is, unless there's some code, perhaps even a framework, doing reflection tricks -- reflection can change "immutable" values, unfortunately.
That's one reason, but there is another reason for it. When you use var
, you can be tempted into reusing the same var
for multiple purposes. This has some problems:
Simply put, using val
is safer and leads to more readable code.
We can, then, go the other direction. If val
is that better, why have var
at all? Well, some languages did take that route, but there are situations in which mutability improves performance, a lot.
For example, take an immutable Queue
. When you either enqueue
or dequeue
things in it, you get a new Queue
object. How then, would you go about processing all items in it?
I'll go through that with an example. Let's say you have a queue of digits, and you want to compose a number out of them. For example, if I have a queue with 2, 1, 3, in that order, I want to get back the number 213. Let's first solve it with a mutable.Queue
:
def toNum(q: scala.collection.mutable.Queue[Int]) = {
var num = 0
while (!q.isEmpty) {
num *= 10
num += q.dequeue
}
num
}
This code is fast and easy to understand. Its main drawback is that the queue that is passed is modified by toNum
, so you have to make a copy of it beforehand. That's the kind of object management that immutability makes you free from.
Now, let's covert it to an immutable.Queue
:
def toNum(q: scala.collection.immutable.Queue[Int]) = {
def recurse(qr: scala.collection.immutable.Queue[Int], num: Int): Int = {
if (qr.isEmpty)
num
else {
val (digit, newQ) = qr.dequeue
recurse(newQ, num * 10 + digit)
}
}
recurse(q, 0)
}
Because I can't reuse some variable to keep track of my num
, like in the previous example, I need to resort to recursion. In this case, it is a tail-recursion, which has pretty good performance. But that is not always the case: sometimes there is just no good (readable, simple) tail recursion solution.
Note, however, that I can rewrite that code to use an immutable.Queue
and a var
at the same time! For example:
def toNum(q: scala.collection.immutable.Queue[Int]) = {
var qr = q
var num = 0
while (!qr.isEmpty) {
val (digit, newQ) = qr.dequeue
num *= 10
num += digit
qr = newQ
}
num
}
This code is still efficient, does not require recursion, and you don't need to worry whether you have to make a copy of your queue or not before calling toNum
. Naturally, I avoided reusing variables for other purposes, and no code outside this function sees them, so I don't need to worry about their values changing from one line to the next -- except when I explicitly do so.
Scala opted to let the programmer do that, if the programmer deemed it to be the best solution. Other languages have chosen to make such code difficult. The price Scala (and any language with widespread mutability) pays is that the compiler doesn't have as much leeway in optimizing the code as it could otherwise. Java's answer to that is optimizing the code based on the run-time profile. We could go on and on about pros and cons to each side.
Personally, I think Scala strikes the right balance, for now. It is not perfect, by far. I think both Clojure and Haskell have very interesting notions not adopted by Scala, but Scala has its own strengths as well. We'll see what comes up on the future.
I had a similar issue. Everything was working before. It's was originally made using Web Forms and later on added Web API for some things.
What worked was, in Visual Studio, change publish profile settings from Release to Debug. Strange, but that's what worked. So sharing here.
To create list of lists, you need to separate them with commas, like this
coin_args = [
["pennies", '2.5', '50.0', '.01'],
["nickles", '5.0', '40.0', '.05'],
["dimes", '2.268', '50.0', '.1'],
["quarters", '5.67', '40.0', '.25']
]
Just write what you really wanted to know:
fac.GetCachedValue("Auto Print Clinical Warnings").ToLower().StartsWith("y")
It's much simpler than anything with substring.
This is flask.jsonify()
def jsonify(*args, **kwargs):
if __debug__:
_assert_have_json()
return current_app.response_class(json.dumps(dict(*args, **kwargs),
indent=None if request.is_xhr else 2), mimetype='application/json')
The json
module used is either simplejson
or json
in that order. current_app
is a reference to the Flask()
object i.e. your application. response_class()
is a reference to the Response()
class.

You can also try using multiprocessing.Process
with daemon=True
; the process.start()
method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.
I experienced similar problem while working with falcon framework and using daemon
process helped.
You'd need to do the following:
from multiprocessing import Process
@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
...
heavy_process = Process( # Create a daemonic process with heavy "my_func"
target=my_func,
daemon=True
)
heavy_process.start()
return Response(
mimetype='application/json',
status=200
)
# Define some heavy function
def my_func():
time.sleep(10)
print("Process finished")
You should get a response immediately and, after 10s you should see a printed message in the console.
NOTE: Keep in mind that daemonic
processes are not allowed to spawn any child processes.
If you simply want to prevent interaction with the select altogether when my_condition is true, you could always just capture the mousedown event and do your event prevent there:
var my_condition = true;
$("#my_select").mousedown(function(e){
if(my_condition)
{
e.preventDefault();
alert("Because my_condition is true, you cannot make this change.");
}
});
This will prevent any change event from ever occurring while my_condition is true.
There can be as many as n(n-1)/2
edges in the graph if not multi-edge is allowed.
And this is achievable if we label the vertices 1,2,...,n
and there's an edge from i
to j
iff i>j
.
See here.
You can use this. Its Tested code
select {
background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right !important;
appearance: none !important;
background-size: 25px 25px !important;
background-position: 99% 50% !important;
}
You can change style directly for scene using .root
class:
.root {
-fx-background-image: url("https://www.google.com/images/srpr/logo3w.png");
}
Add this to CSS and load it as "Uluk Biy" described in his answer.
Of course the performance of the hashmap will depend based on the quality of the hashCode() function for the given object. However, if the function is implemented such that the possibility of collisions is very low, it will have a very good performance (this is not strictly O(1) in every possible case but it is in most cases).
For example the default implementation in the Oracle JRE is to use a random number (which is stored in the object instance so that it doesn't change - but it also disables biased locking, but that's an other discussion) so the chance of collisions is very low.
Make sure the value in the child's project/parent/version node matches its parent's project/version value
I am posting a way to use _netrc
to download materials from the site www.course.com.
If someone is going to use the coursera-dl to download the open-class materials on www.coursera.com, and on the Windows OS someone wants to use a file like ".netrc" which is in like-Unix OS to add the option -n
instead of -U <username> -P <password>
for convenience. He/she can do it like this:
Check the home path on Windows OS: setx HOME %USERPROFILE%
(refer to VonC's answer). It will save the HOME
environment variable as C:\Users\"username"
.
Locate into the directory C:\Users\"username"
and create a file name _netrc
.NOTE: there is NOT any suffix.
the content is like: machine coursera-dl login <user> password <pass>
Use a command like coursera-dl -n --path PATH <course name>
to download the class materials. More coursera-dl options details for this page.
np.convolve()
takes one dimension array. You need to check the input and convert it into 1D.
You can use the np.ravel()
, to convert the array to one dimension.
Sed is a little ugly, you could do it elegantly like so:
hendry@i7 tmp$ cat foo
bar
candy
car
hendry@i7 tmp$ for i in `cat foo`; do echo ${i}bar; done
barbar
candybar
carbar
You can use bash. Note for very large files in terms of GB, use awk/wc
. However it should still be manageable in performance for files with a few MB.
declare -i count=0
while read
do
((count++))
done < file
echo "line count: $count"

Try with event.target
Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.
The "break" command does not work within an "if" statement.
If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.
"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).
Although using File.separator to reference a file name is overkill (for those who imagine far off lands, I imagine their JVM implementation would replace a /
with a :
just like the windows jvm replaces it with a \
).
However, sometimes you are getting the file reference, not creating it, and you need to parse it, and to be able to do that, you need to know the separator on the platform. File.separator helps you do that.
I know this is an old question, but looking at the original question, it looks like the user just wanted to run a command as root, that's what I need to do when I was searching for an answer and stumbled across the question.
So this one is worth knowing in my opinion:
vagrant ssh servername -c "echo vagrant | sudo -S shutdown 0"
vagrant
is the password being echoed into the the sudo command, because as we all know, the vagrant account has sudo privileges and when you sudo, you need to specify the password of the user account, not root..and of course by default, the vagrant user's password is vagrant
!
By default you need root privileges to shutdown so I guess doing a shutdown is a good test.
Obviously you don't need to specify a server name if there is only one for that vagrant environment. Also, we're talking about local vagrant virtual machine to the host, so there isn't really any security issue that I can see.
Hope this helps.

Instead of using <hr>, you can one of the border of the enclosing block and display it as a horizontal line.
Here is a sample code:
The HTML:
<div class="title_block">
<h3>This is a header.</h3>
</div>
<p>Here is some sample paragraph text.<br>
This demonstrates that a horizontal line goes between the title and the paragraph.</p>
The CSS:
.title_block {
border-bottom: 1px solid #ddd;
padding-bottom: 5px;
margin-bottom: 5px;
}

Please note that this answer was written for Mac OS El Capitan. For newer versions, beware that it may no longer apply. In particular, the legacy option is quite possibly deprecated.
There are two solutions to the problem, and they are both mentioned in other answers to this question and to How to get gdb to work using macports under OSX 10.11 El Capitan?, but to clear up some confusion here is my summary (as an answer since it got a bit long for a comment):
Which alternative is more secure I guess boils down to the choice between 1) trusting self-signed certificates and 2) giving users more privileges.
If the signature alternative is used, disabling SIP to add the -p option to taskgated
is not required.
However, note that with this alternative, debugging is only allowed for users in the _developer
group.
Using codesign to sign using a cert named gdb-cert
:
codesign -s gdb-cert /opt/local/bin/ggdb
(using the MacPorts standard path, adopt as necessary)
For detailed code-signing recipes (incl cert creation), see : https://gcc.gnu.org/onlinedocs/gcc-4.8.1/gnat_ugn_unw/Codesigning-the-Debugger.html or https://sourceware.org/gdb/wiki/BuildingOnDarwin
Note that you need to restart the keychain application and the taskgated service during and after the process (the easiest way is to reboot).
As per the answer by @user14241, disabling SIP and adding the -p option to taskgated
is an option. Note that if using this option, signing the binary is not needed, and it also bypasses the dialog for authenticating as a member of the Developer Tools group (_developer
).
After adding the -p option (allow groups procmod and procview) to taskgated you also need to add the users that should be allowed to use gdb to the procmod group.
The recipe is:
restart in recovery mode, open a terminal and run csrutil disable
restart machine and edit /System/Library/LaunchDaemons/com.apple.taskgated.plist
, adding
the -p
opion:
<array>
<string>/usr/libexec/taskgated</string>
<string>-sp</string>
</array>
restart in recovery mode to reenable SIP (csrutil enable
)
restart machine and add user USERNAME
to the group procmod
:
sudo dseditgroup -o edit -a USERNAME -t user procmod
An alternative that does not involve adding users to groups is to make the executable setgid procmod, as that also makes procmod
the effective group id of any user executing the setgid binary (suggested in https://apple.stackexchange.com/a/112132)
sudo chgrp procmod /path/to/gdb
sudo chmod g+s /path/to/gdb
You can also get the tenant id, in fact all subscription details by logging into the url resources.azure.com
You can try:
int priceDecimalPlaces =
price.ToString(System.Globalization.CultureInfo.InvariantCulture)
.Split('.')[1].Length;
Commons-net surely. :) Most open source projects use it these days.

In my opinion, the simplest way to get the amount of selected rows is the following:
The cursor object returns a list with the results when using the fetch commands (fetchall(), fetchone(), fetchmany()). To get the selected rows just print the length of this list. But it just makes sense for fetchall(). ;-)
Example:
print len(cursor.fetchall)
Change the FormBorderStyle
to one of the fixed values: FixedSingle
, Fixed3D
,
FixedDialog
or FixedToolWindow
.
The FormBorderStyle
property is under the Appearance category.
Or check this:
// Define the border style of the form to a dialog box.
form1.FormBorderStyle = FormBorderStyle.FixedDialog;
// Set the MaximizeBox to false to remove the maximize box.
form1.MaximizeBox = false;
// Set the MinimizeBox to false to remove the minimize box.
form1.MinimizeBox = false;
// Set the start position of the form to the center of the screen.
form1.StartPosition = FormStartPosition.CenterScreen;
// Display the form as a modal dialog box.

I am running JConsole/JVisualVm on windows hooking to tomcat running Linux Redhat ES3.
Disabling packet filtering using the following command did the trick for me:
/usr/sbin/iptables -I INPUT -s jconsole-host -p tcp --destination-port jmxremote-port -j ACCEPT
where jconsole-host is either the hostname or the host address on which JConsole runs on and jmxremote-port is the port number set for com.sun.management.jmxremote.port for remote management.
there are a couple of ways of using a timer:
1) scheduled timer & using selector
NSTimer *t = [NSTimer scheduledTimerWithTimeInterval: 2.0
target: self
selector:@selector(onTick:)
userInfo: nil repeats:NO];
As a side note, instead of using a timer that doesn't repeat and calls the selector after a specified interval, you could use a simple statement like this:
[self performSelector:@selector(onTick:) withObject:nil afterDelay:2.0];
this will have the same effect as the sample code above; but if you want to call the selector every nth time, you use the timer with repeats:YES;
2) self-scheduled timer
NSDate *d = [NSDate dateWithTimeIntervalSinceNow: 60.0];
NSTimer *t = [[NSTimer alloc] initWithFireDate: d
interval: 1
target: self
selector:@selector(onTick:)
userInfo:nil repeats:YES];
NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer:t forMode: NSDefaultRunLoopMode];
[t release];
3) unscheduled timer & using invocation
NSMethodSignature *sgn = [self methodSignatureForSelector:@selector(onTick:)];
NSInvocation *inv = [NSInvocation invocationWithMethodSignature: sgn];
[inv setTarget: self];
[inv setSelector:@selector(onTick:)];
NSTimer *t = [NSTimer timerWithTimeInterval: 1.0
invocation:inv
repeats:YES];
and after that, you start the timer manually whenever you need like this:
NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer: t forMode: NSDefaultRunLoopMode];
And as a note, onTick: method looks like this:
-(void)onTick:(NSTimer *)timer {
//do smth
}
If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.
To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.
Then click 'Microsoft WCF Web Service Reference':
Enter the file path into URI text box and import the WSDL:
It will generate a simple, very basic WCF client and you to use it something like this:
YourServiceClient client = new YourServiceClient();
client.DoSomething();
Make sure that nothing is interfering with your app files (specially in Windows), in my case this problem arise due to a text editor that was holding some XML file and Android Studio wasn't able to modify it.
Simple way is:

And another option is Kannel a free WAP and SMS gateway.
I used GENEGC's script, but I found it quite slow.
It is slow because it scans whole sheet on every edit.
So I wrote way faster and cleaner method for myself and I wanted to share it.
function onEdit(e) {
if (e) {
var ss = e.source.getActiveSheet();
var r = e.source.getActiveRange();
// If you want to be specific
// do not work in first row
// do not work in other sheets except "MySheet"
if (r.getRow() != 1 && ss.getName() == "MySheet") {
// E.g. status column is 2nd (B)
status = ss.getRange(r.getRow(), 2).getValue();
// Specify the range with which You want to highlight
// with some reading of API you can easily modify the range selection properties
// (e.g. to automatically select all columns)
rowRange = ss.getRange(r.getRow(),1,1,19);
// This changes font color
if (status == 'YES') {
rowRange.setFontColor("#999999");
} else if (status == 'N/A') {
rowRange.setFontColor("#999999");
// DEFAULT
} else if (status == '') {
rowRange.setFontColor("#000000");
}
}
}
}

Possibly you can do group by user and then order by time desc. Something like as below
SELECT * FROM lms_attendance group by user order by time desc;
In PHP5, you should use the Document Object Model class instead. Example:
$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);
$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);
$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);
echo htmlentities($domDoc->saveXML());
This is working for me, as described in this thread:
declare let something: string;
something = 'foo';
I think it should be:
dataGridView1.Columns[0].HeaderCell.Value = "my text";
In 2014 along with iOS 8 and XCode 6 apple introduced Beta Testing of iOS App using iTunes Connect.
You can upload your build to iTunes connect and invite testers using their mail id's. You can invite up to 2000 external testers using just their email address. And they can install the beta app through TestFlight
I think this method my solve your problem:
public static void attachFragment ( int fragmentHolderLayoutId, Fragment fragment, Context context, String tag ) {
FragmentManager manager = ( (AppCompatActivity) context ).getSupportFragmentManager ();
FragmentTransaction ft = manager.beginTransaction ();
if (manager.findFragmentByTag ( tag ) == null) { // No fragment in backStack with same tag..
ft.add ( fragmentHolderLayoutId, fragment, tag );
ft.addToBackStack ( tag );
ft.commit ();
}
else {
ft.show ( manager.findFragmentByTag ( tag ) ).commit ();
}
}

You can use --dbpath flag in order to provide it with the parameters i.e, the directory address. I found it useful for Windows 10 OS.
With the default settings it is usually not required.
Those extensions aren't really new, they are old. :-)
When C++ was new, some people wanted to have a .c++ extension for the source files, but that didn't work on most file systems. So they tried something close to that, like .cxx, or .cpp instead.
Others thought about the language name, and "incrementing" .c to get .cc or even .C in some cases. Didn't catch on that much.
Some believed that if the source is .cpp, the headers ought to be .hpp to match. Moderately successful.
Just write:
<script>
var my_variable_name = "<?php echo $php_string; ?>";
</script>
Now it's available as a JavaScript variable by the name of my_variable_name
at any point below the above code.
Adding onKeyPress will work onChange in Text Field.
<TextField
onKeyPress={(ev) => {
console.log(`Pressed keyCode ${ev.key}`);
if (ev.key === 'Enter') {
// Do code here
ev.preventDefault();
}
}}
/>
I'm surprised that no-one's mentioned this but you could just create an interface called ObjectLiteral
, that accepts key: value
pairs of type string: any
:
interface ObjectLiteral {
[key: string]: any;
}
Then you'd use it, like this:
let data: ObjectLiteral = {
hello: "world",
goodbye: 1,
// ...
};
An added bonus is that you can re-use this interface many times as you need, on as many objects you'd like.
Good luck.
These are the droids you're looking for. This is taken from validator.js which is the library you should really use to do this. But if you want to roll your own, who am I to stop you? If you want pure regex then you can just take out the length check. I think it's a good idea to test the length of the URL though if you really want to determine compliance with the spec.
function isURL(str) {
var urlRegex = '^(?!mailto:)(?:(?:http|https|ftp)://)(?:\\S+(?::\\S*)?@)?(?:(?:(?:[1-9]\\d?|1\\d\\d|2[01]\\d|22[0-3])(?:\\.(?:1?\\d{1,2}|2[0-4]\\d|25[0-5])){2}(?:\\.(?:[0-9]\\d?|1\\d\\d|2[0-4]\\d|25[0-4]))|(?:(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)(?:\\.(?:[a-z\\u00a1-\\uffff0-9]+-?)*[a-z\\u00a1-\\uffff0-9]+)*(?:\\.(?:[a-z\\u00a1-\\uffff]{2,})))|localhost)(?::\\d{2,5})?(?:(/|\\?|#)[^\\s]*)?$';
var url = new RegExp(urlRegex, 'i');
return str.length < 2083 && url.test(str);
}
try $conn = mysql_connect("localhost", "root")
or $conn = mysql_connect("localhost", "root", "")
You can treat your text file as a python module and load it dynamically using imp.load_source
:
import imp
imp.load_source( name, pathname[, file])
Example:
// mydata.txt
var1 = 'hi'
var2 = 'how are you?'
var3 = { 1:'elem1', 2:'elem2' }
//...
// In your script file
def getVarFromFile(filename):
import imp
f = open(filename)
global data
data = imp.load_source('data', '', f)
f.close()
# path to "config" file
getVarFromFile('c:/mydata.txt')
print data.var1
print data.var2
print data.var3
...
Since Java 1.8, you can achieve this without an extra library by using the java.time classes. See Tutorial.
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
formatter = formatter.withLocale( putAppropriateLocaleHere ); // Locale specifies human language for translating, and cultural norms for lowercase/uppercase and abbreviations and such. Example: Locale.US or Locale.CANADA_FRENCH
LocalDate date = LocalDate.parse("2005-nov-12", formatter);
The syntax is nearly the same though.
You can use the CURSOR_STATUS function to determine its state.
IF CURSOR_STATUS('global','myCursor')>=-1
BEGIN
DEALLOCATE myCursor
END
I had to change my values/styles.xml to
<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
Before that change, it was without 'Base'.

Here's an easy way for Windows users.
Update (2018-01-06): This answer is obsolete. Modern versions of PyCharm provide Paths via Settings ? Project Interpreter ? ? ? Show All ? Show paths button.
PyCharm Professional Edition has the Paths
tab in Python Interpreters
settings, but Community Edition apparently doesn't have it.
As a workaround, you can create a symlink for your imported library under your project's root.
For example:
myproject
mypackage
__init__.py
third_party -> /some/other/directory/third_party
A heap queue is a generalised solution which allows you to extract the top n keys ordered by value:
from heapq import nlargest
stats = {'a':1000, 'b':3000, 'c': 100}
res1 = nlargest(1, stats, key=stats.__getitem__) # ['b']
res2 = nlargest(2, stats, key=stats.__getitem__) # ['b', 'a']
res1_val = next(iter(res1)) # 'b'
Note dict.__getitem__
is the method called by the syntactic sugar dict[]
. As opposed to dict.get
, it will return KeyError
if a key is not found, which here cannot occur.
What @forhas and @HRgiger did also worked for me. I am using spring-data-mongodb
instead of jpa
.
However, for mongodb bindings, you should not remove the version of mongodb reference xsd, just keep it with version: http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
. context
and beans
versions should be removed.
Yes you can...
WITH SET1 AS (SELECT SYSDATE FROM DUAL), -- SET1 initialised
SET2 AS (SELECT * FROM SET1) -- SET1 accessed
SELECT * FROM SET2; -- SET2 projected

Follow the order in which it should be initialized in Common Table Expressions
You can easily do this by using UIAlertController
let alertController = UIAlertController(
title: "Your title", message: "Your message", preferredStyle: .alert)
let defaultAction = UIAlertAction(
title: "Close Alert", style: .default, handler: nil)
//you can add custom actions as well
alertController.addAction(defaultAction)
present(alertController, animated: true, completion: nil)
.

I agree with the accepted answer. But for me, the issue was not that, instead I had to modify my Servlet-Class name from:-
<servlet-class>org.glassfish.jersey.servlet.ServletContainer.class</servlet-class>
To:
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
So, removing .class worked fine in my case. Hope it will help somebody!
The following should give you the number of "real" cores on both a hyperthreaded and non-hyperthreaded system. At least it worked in all my tests.
awk -F: '/^physical/ && !ID[$2] { P++; ID[$2]=1 }; /^cpu cores/ { CORES=$2 }; END { print CORES*P }' /proc/cpuinfo
You can use the below code for it.
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
Since the getTime function of the Date object gets the milliseconds since 1970/01/01, we can do this:
var time = '12:23:00';
var seconds = new Date('1970-01-01T' + time + 'Z').getTime() / 1000;
The jQueryUI provides a extension to animate
function that allows you to animate css class.
edit: Example here
There are also methods to add/remove/toggle class which you might also be interested in.
git reset --hard CommitId
git push -f origin master
1st command will rest your head to commitid and 2nd command will delete all commit after that commit id on master branch.
Note: Don't forget to add -f in push otherwise it will be rejected.
INSERT INTO atable (x,y,z) VALUES ( NULL,NULL,NULL)
Running an intent service will be easier. Service in creating a thread in the application but it's still in the application.
Use this one:
Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")
Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")
With rng.Validation
.Delete 'delete previous validation
.Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
Formula1:="='" & ws.Name & "'!" & range1.Address
End With
Note that when you're using Dim range1, rng As range
, only rng
has type of Range
, but range1
is Variant
. That's why I'm using Dim range1 As Range, rng As Range
.
About meaning of parameters you can read is MSDN, but in short:
Type:=xlValidateList
means validation type, in that case you should select value from listAlertStyle:=xlValidAlertStop
specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.Operator:= xlBetween
is odd. It can be used only if two formulas are provided for validation.Formula1:="='" & ws.Name & "'!" & range1.Address
for list data validation provides address of list with values (in format =Sheet!A1:A5
)You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.
$data = array(
array(
"title" => "Another title",
"date" => "Fri, 17 Jun 2011 08:55:57 +0200"
),
array(
"title" => "My title",
"date" => "Mon, 16 Jun 2010 06:55:57 +0200"
)
);
function sortFunction( $a, $b ) {
return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);
