I tried accepted answer and got message saying generated excel file is corrupted when trying to open. I was able to fix it by doing few modifications like adding below line end of the code.
workbookPart.Workbook.Save();
I have posted full code @ Export DataTable to Excel with Open XML in c#
I modified the /etc/sysconfig/ip6tables-config
file changing:
IP6TABLES_SAVE_ON_STOP="no"
To:
IP6TABLES_SAVE_ON_STOP="yes"
And this:
IP6TABLES_SAVE_ON_RESTART="no"
To:
IP6TABLES_SAVE_ON_RESTART="yes"
This seemed to save the changes I made using the iptables commands through a reboot.
You can use the apply
function of the Series
object:
>>> df = pd.DataFrame([[' a ', 10], [' c ', 5]])
>>> df[0][0]
' a '
>>> df[0] = df[0].apply(lambda x: x.strip())
>>> df[0][0]
'a'
Note the usage of
strip
and not theregex
which is much faster
Another option - use the apply
function of the DataFrame object:
>>> df = pd.DataFrame([[' a ', 10], [' c ', 5]])
>>> df.apply(lambda x: x.apply(lambda y: y.strip() if type(y) == type('') else y), axis=0)
0 1
0 a 10
1 c 5
synchronous / asynchronous is to describe the relation between two modules.
blocking / non-blocking is to describe the situation of one module.
An example:
Module X: "I".
Module Y: "bookstore".
X asks Y: do you have a book named "c++ primer"?
blocking: before Y answers X, X keeps waiting there for the answer. Now X (one module) is blocking. X and Y are two threads or two processes or one thread or one process? we DON'T know.
non-blocking: before Y answers X, X just leaves there and do other things. X may come back every two minutes to check if Y has finished its job? Or X won't come back until Y calls him? We don't know. We only know that X can do other things before Y finishes its job. Here X (one module) is non-blocking. X and Y are two threads or two processes or one process? we DON'T know. BUT we are sure that X and Y couldn't be one thread.
synchronous: before Y answers X, X keeps waiting there for the answer. It means that X can't continue until Y finishes its job. Now we say: X and Y (two modules) are synchronous. X and Y are two threads or two processes or one thread or one process? we DON'T know.
asynchronous: before Y answers X, X leaves there and X can do other jobs. X won't come back until Y calls him. Now we say: X and Y (two modules) are asynchronous. X and Y are two threads or two processes or one process? we DON'T know. BUT we are sure that X and Y couldn't be one thread.
Please pay attention on the two bold-sentences above. Why does the bold-sentence in the 2) contain two cases whereas the bold-sentence in the 4) contains only one case? This is a key of the difference between non-blocking and asynchronous.
Here is a typical example about non-blocking & synchronous:
// thread X
while (true)
{
msg = recv(Y, NON_BLOCKING_FLAG);
if (msg is not empty)
{
break;
}
else
{
sleep(2000); // 2 sec
}
}
// thread Y
// prepare the book for X
send(X, book);
You can see that this design is non-blocking (you can say that most of time this loop does something nonsense but in CPU's eyes, X is running, which means that X is non-blocking) whereas X and Y are synchronous because X can't continue to do any other things(X can't jump out of the loop) until it gets the book from Y.
Normally in this case, make X blocking is much better because non-blocking spends much resource for a stupid loop. But this example is good to help you understand the fact: non-blocking doesn't mean asynchronous.
The four words do make us confused easily, what we should remember is that the four words serve for the design of architecture. Learning about how to design a good architecture is the only way to distinguish them.
For example, we may design such a kind of architecture:
// Module X = Module X1 + Module X2
// Module X1
while (true)
{
msg = recv(many_other_modules, NON_BLOCKING_FLAG);
if (msg is not null)
{
if (msg == "done")
{
break;
}
// create a thread to process msg
}
else
{
sleep(2000); // 2 sec
}
}
// Module X2
broadcast("I got the book from Y");
// Module Y
// prepare the book for X
send(X, book);
In the example here, we can say that
If you need, you can also describe those threads created in X1 with the four words.
The more important things are: when do we use synchronous instead of asynchronous? when do we use blocking instead of non-blocking? Is making X1 blocking better than non-blocking? Is making X and Y synchronous better than asynchronous? Why is Nginx non-blocking? Why is Apache blocking? These questions are what you must figure out.
To make a good choice, you must analyze your need and test the performance of different architectures. There is no such an architecture that is suitable for various of needs.
You first have to 'dot' source the script, so for you :
. .\Get-NetworkStatistics.ps1
The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted
or set-ExecutionPolicy AllSigned
see(the Execution Policy instructions).
You can use mx.DateTime module
import mx.DateTime as mt
t1 = mt.now()
t2 = mt.now()
print int((t2-t1).seconds)
Sure, just do
```{r someVar, echo=FALSE}
someVariable
```
to show some (previously computed) variable someVariable
. Or run code that prints etc pp.
So for plotting, I have eg
### Impact of choice of ....
```{r somePlot, echo=FALSE}
plotResults(Res, Grid, "some text", "some more text")
```
where the plotting function plotResults
is from a local package.
Here is a variant of Avi Ginsburg's program which clearly illustrates the property of reinterpret_cast
mentioned by Chris Luengo, flodin, and cmdLP: that the compiler treats the pointed-to memory location as if it were an object of the new type:
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
class A
{
public:
int i;
};
class B : public A
{
public:
virtual void f() {}
};
int main()
{
string s;
B b;
b.i = 0;
A* as = static_cast<A*>(&b);
A* ar = reinterpret_cast<A*>(&b);
B* c = reinterpret_cast<B*>(ar);
cout << "as->i = " << hex << setfill('0') << as->i << "\n";
cout << "ar->i = " << ar->i << "\n";
cout << "b.i = " << b.i << "\n";
cout << "c->i = " << c->i << "\n";
cout << "\n";
cout << "&(as->i) = " << &(as->i) << "\n";
cout << "&(ar->i) = " << &(ar->i) << "\n";
cout << "&(b.i) = " << &(b.i) << "\n";
cout << "&(c->i) = " << &(c->i) << "\n";
cout << "\n";
cout << "&b = " << &b << "\n";
cout << "as = " << as << "\n";
cout << "ar = " << ar << "\n";
cout << "c = " << c << "\n";
cout << "Press ENTER to exit.\n";
getline(cin,s);
}
Which results in output like this:
as->i = 0
ar->i = 50ee64
b.i = 0
c->i = 0
&(as->i) = 00EFF978
&(ar->i) = 00EFF974
&(b.i) = 00EFF978
&(c->i) = 00EFF978
&b = 00EFF974
as = 00EFF978
ar = 00EFF974
c = 00EFF974
Press ENTER to exit.
It can be seen that the B object is built in memory as B-specific data first, followed by the embedded A object. The static_cast
correctly returns the address of the embedded A object, and the pointer created by static_cast
correctly gives the value of the data field. The pointer generated by reinterpret_cast
treats b
's memory location as if it were a plain A object, and so when the pointer tries to get the data field it returns some B-specific data as if it were the contents of this field.
One use of reinterpret_cast
is to convert a pointer to an unsigned integer (when pointers and unsigned integers are the same size):
int i;
unsigned int u = reinterpret_cast<unsigned int>(&i);

You can try this with Color.FromArgb
:
Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));
Also u can consider this
$('#select_2').find('option:selected').text();
which might be a little faster solution though I am not sure.
Try to use toISOString(). It returns string in ISO8601 format.
from javascript
$.get('/example/doGet?date=' + new Date().toISOString(), function (result) {
console.log(result);
});
from c#
[HttpGet]
public JsonResult DoGet(DateTime date)
{
return Json(date.ToString(), JsonRequestBehavior.AllowGet);
}
Question content may have changed, so I'll try to answer thoroughly.
Destructuring allows you to pull values out of anything with properties. You can also define default values when null/undefined and name aliases.
const options = {
filters : {
firstName : "abc"
}
}
const {filters: {firstName = "John", lastName = "Smith"}} = options
// firstName = "abc"
// lastName = "Smith"
NOTE: Capitalization matters
If working with an array, here is how you do it.
In this case, name is extracted from each object in the array, and given its own alias. Since the object might not exist = {}
was also added.
const options = {
filters: [{
name: "abc",
value: "lots"
}]
}
const {filters:[{name : filter1 = "John"} = {}, {name : filter2 = "Smith"} = {}]} = options
// filter1 = "abc"
// filter2 = "Smith"

If you are using .NET framework 4.5 you can use System.Net.WebUtility.HtmlDecode() which takes a HTML encoded string and returns a decoded string.

I installed cudatoolkit 11 and copy dll
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.1\bin
to C:\Windows\System32
.
It fixed for PyCharm but not for Anaconda jupyter:

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read
public class MyClass implements MyInterface {
public void find(int x) throws A_Exception, B_Exception{
----
----
---
}
}
Then an interface would look like this
public interface MyInterface {
void find(int x) throws A_Exception, B_Exception;
}
For a single boxplot:
import seaborn as sb
sb.boxplot(data=Array).set_title('Title')
For more boxplot in the same plot:
import seaborn as sb
sb.boxplot(data=ArrayofArray).set_title('Title')
e.g.
import seaborn as sb
myarray=[78.195229, 59.104538, 19.884109, 25.941648, 72.234825, 82.313911]
sb.boxplot(data=myarray).set_title('myTitle')
The DebuggerHiddenAttribute which allows to avoiding step into code which should not be debugged.
public static class CustomDebug
{
[DebuggerHidden]
public static void Assert(Boolean condition, Func<Exception> exceptionCreator) { ... }
}
...
// The following assert fails, and because of the attribute the exception is shown at this line
// Isn't affecting the stack trace
CustomDebug.Assert(false, () => new Exception());
Also it prevents from showing methods in stack trace, useful when having a method which just wraps another method:
[DebuggerHidden]
public Element GetElementAt(Vector2 position)
{
return GetElementAt(position.X, position.Y);
}
public Element GetElementAt(Single x, Single y) { ... }
If you now call GetElementAt(new Vector2(10, 10))
and a error occurs at the wrapped method, the call stack is not showing the method which is calling the method which throws the error.
It's a great idea to use cURL as suggested by rojoca.
Here is an example. You can monitor text.txt while the script is running in background:
<?php
function doCurl($begin)
{
echo "Do curl<br />\n";
$url = 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
$url = preg_replace('/\?.*/', '', $url);
$url .= '?begin='.$begin;
echo 'URL: '.$url.'<br>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
echo 'Result: '.$result.'<br>';
curl_close($ch);
}
if (empty($_GET['begin'])) {
doCurl(1);
}
else {
while (ob_get_level())
ob_end_clean();
header('Connection: close');
ignore_user_abort();
ob_start();
echo 'Connection Closed';
$size = ob_get_length();
header("Content-Length: $size");
ob_end_flush();
flush();
$begin = $_GET['begin'];
$fp = fopen("text.txt", "w");
fprintf($fp, "begin: %d\n", $begin);
for ($i = 0; $i < 15; $i++) {
sleep(1);
fprintf($fp, "i: %d\n", $i);
}
fclose($fp);
if ($begin < 10)
doCurl($begin + 1);
}
?>

first you need to add 2 columns to datagrid. you may do it at design time. see Columns property. then add rows as much as you need.
this.dataGridView1.Rows.Add("1", "XX");
There could be 3 solution from this posting and other answer.
Solution 1
var lastScrollTop = 0;
$(window).on('scroll', function() {
st = $(this).scrollTop();
if(st < lastScrollTop) {
console.log('up 1');
}
else {
console.log('down 1');
}
lastScrollTop = st;
});
Solution 2
$('body').on('DOMMouseScroll', function(e){
if(e.originalEvent.detail < 0) {
console.log('up 2');
}
else {
console.log('down 2');
}
});
Solution 3
$('body').on('mousewheel', function(e){
if(e.originalEvent.wheelDelta > 0) {
console.log('up 3');
}
else {
console.log('down 3');
}
});
I couldn't tested it on Safari
chrome 42 (Win 7)
Firefox 37 (Win 7)
IE 11 (Win 8)
IE 10 (Win 7)
IE 9 (Win 7)
IE 8 (Win 7)
I checked that side effect from IE 11 and IE 8 is come from
if else
statement. So, I replaced it withif else if
statement as following.
From the multi browser test, I decided to use Solution 3 for common browsers and Solution 1 for firefox and IE 11.
I referred this answer to detect IE 11.
// Detect IE version
var iev=0;
var ieold = (/MSIE (\d+\.\d+);/.test(navigator.userAgent));
var trident = !!navigator.userAgent.match(/Trident\/7.0/);
var rv=navigator.userAgent.indexOf("rv:11.0");
if (ieold) iev=new Number(RegExp.$1);
if (navigator.appVersion.indexOf("MSIE 10") != -1) iev=10;
if (trident&&rv!=-1) iev=11;
// Firefox or IE 11
if(typeof InstallTrigger !== 'undefined' || iev == 11) {
var lastScrollTop = 0;
$(window).on('scroll', function() {
st = $(this).scrollTop();
if(st < lastScrollTop) {
console.log('Up');
}
else if(st > lastScrollTop) {
console.log('Down');
}
lastScrollTop = st;
});
}
// Other browsers
else {
$('body').on('mousewheel', function(e){
if(e.originalEvent.wheelDelta > 0) {
console.log('Up');
}
else if(e.originalEvent.wheelDelta < 0) {
console.log('Down');
}
});
}
It means that somewhere in your code, you are calling a function which in turn calls another function and so forth, until you hit the call stack limit.
This is almost always because of a recursive function with a base case that isn't being met.
Consider this code...
(function a() {
a();
})();
Here is the stack after a handful of calls...
As you can see, the call stack grows until it hits a limit: the browser hardcoded stack size or memory exhaustion.
In order to fix it, ensure that your recursive function has a base case which is able to be met...
(function a(x) {
// The following condition
// is the base case.
if ( ! x) {
return;
}
a(--x);
})(10);

If you actually start a new thread, that thread will terminate when the method finishes:
Thread thread = new Thread(SecondFoo);
thread.Start();
Now SecondFoo
will be called in the new thread, and the thread will terminate when it completes.
Did you actually mean that you wanted the thread to terminate when the method in the calling thread completes?
EDIT: Note that starting a thread is a reasonably expensive operation. Do you definitely need a brand new thread rather than using a threadpool thread? Consider using ThreadPool.QueueUserWorkItem
or (preferrably, if you're using .NET 4) TaskFactory.StartNew
.
I recently wanted a very light-weight logging class that would output varying amounts of output depending on the logging level that could be programmatically set. But I didn't want to instantiate the class every time I wanted to output a debugging message or error or warning. But I also wanted to encapsulate the functioning of this logging facility and make it reusable without the declaration of any globals.
So I used class variables and the @classmethod
decorator to achieve this.
With my simple Logging class, I could do the following:
Logger._level = Logger.DEBUG
Then, in my code, if I wanted to spit out a bunch of debugging information, I simply had to code
Logger.debug( "this is some annoying message I only want to see while debugging" )
Errors could be out put with
Logger.error( "Wow, something really awful happened." )
In the "production" environment, I can specify
Logger._level = Logger.ERROR
and now, only the error message will be output. The debug message will not be printed.
Here's my class:
class Logger :
''' Handles logging of debugging and error messages. '''
DEBUG = 5
INFO = 4
WARN = 3
ERROR = 2
FATAL = 1
_level = DEBUG
def __init__( self ) :
Logger._level = Logger.DEBUG
@classmethod
def isLevel( cls, level ) :
return cls._level >= level
@classmethod
def debug( cls, message ) :
if cls.isLevel( Logger.DEBUG ) :
print "DEBUG: " + message
@classmethod
def info( cls, message ) :
if cls.isLevel( Logger.INFO ) :
print "INFO : " + message
@classmethod
def warn( cls, message ) :
if cls.isLevel( Logger.WARN ) :
print "WARN : " + message
@classmethod
def error( cls, message ) :
if cls.isLevel( Logger.ERROR ) :
print "ERROR: " + message
@classmethod
def fatal( cls, message ) :
if cls.isLevel( Logger.FATAL ) :
print "FATAL: " + message
And some code that tests it just a bit:
def logAll() :
Logger.debug( "This is a Debug message." )
Logger.info ( "This is a Info message." )
Logger.warn ( "This is a Warn message." )
Logger.error( "This is a Error message." )
Logger.fatal( "This is a Fatal message." )
if __name__ == '__main__' :
print "Should see all DEBUG and higher"
Logger._level = Logger.DEBUG
logAll()
print "Should see all ERROR and higher"
Logger._level = Logger.ERROR
logAll()
Since your keys are strings and since we are talking about readability, I prefer :
mydict = dict(
key1 = 1,
key2 = 2,
key3 = 3
)

I'd suggest using such extension method:
public static class DataColumnCollectionExtensions
{
public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
{
return source.Cast<DataColumn>();
}
}
And therefore:
string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();
You may also implement one more extension method for DataTable
class to reduce code:
public static class DataTableExtensions
{
public static IEnumerable<DataColumn> GetColumns(this DataTable source)
{
return source.Columns.AsEnumerable();
}
}
And use it as follows:
string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();
you might want to start with max(trans_seq_no) + 1.

If you're trying to do the 'gapless' thing, I strongly advise you to
One interesting location where interfaces fare better than abstract classes is when you need to add extra functionality to a group of (related or unrelated) objects. If you cannot give them a base abstract class (e.g., they are sealed
or already have a parent), you can give them a dummy (empty) interface instead, and then simply write extension methods for that interface.
// Set flash data
$this->session->set_flashdata('message_name', 'This is my message');
// After that you need to used redirect function instead of load view such as
redirect("admin/signup");
// Get Flash data on view
$this->session->flashdata('message_name');
Vectors effectively are arrays under the skin. If you have a function:
void f( double a[]);
you can call it like this:
vector <double> v;
v.push_back( 1.23 )
f( &v[0] );
You should not ever need to convert a vector into an actual array instance.

The shortcuts preserve your cursor position and your comments as long as they start with #
(there is space after #). For example:
# variable x
x = 0
After commenting:
# variable x
#x = 0
After uncomennting:
# variable x
x = 0
You can add the command in the /etc/rc.local

You can remove the back button by passing an empty new Container()
as the leading
argument to your AppBar
.
If you find yourself doing this, you probably don't want the user to be able to press the device's back button to get back to the earlier route. Instead of calling pushNamed
, try calling Navigator.pushReplacementNamed
to cause the earlier route to disappear.
The function pushReplacementNamed
will remove the previous route in the backstack and replace it with the new route.
Full code sample for the latter is below.
import 'package:flutter/material.dart';
class LogoutPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text("Logout Page"),
),
body: new Center(
child: new Text('You have been logged out'),
),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text("Remove Back Button"),
),
floatingActionButton: new FloatingActionButton(
child: new Icon(Icons.fullscreen_exit),
onPressed: () {
Navigator.pushReplacementNamed(context, "/logout");
},
),
);
}
}
void main() {
runApp(new MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
home: new MyHomePage(),
routes: {
"/logout": (_) => new LogoutPage(),
},
);
}
}
If you want to run test methods in a specific order in JUnit 5, you can use the below code.
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
public class MyClassTest {
@Test
@Order(1)
public void test1() {}
@Test
@Order(2)
public void test2() {}
}
you need to put it after wp_head(); Because that loads your jQuery and you need to load jQuery first and then your js
The IEnumerable<T>
interface does not include an indexer, you're probably confusing it with IList<T>
If the object really is an IList<T>
(e.g. List<T>
or an array T[]
), try making the reference to it of type IList<T>
too.
Otherwise, you can use myEnumerable.ElementAt(index)
which uses the Enumerable.ElementAt extension method. This should work for all IEnumerable<T>
s .
Note that unless the (run-time) object implements IList<T>
, this will cause all of the first index + 1
items to be enumerated, with all but the last being discarded.
EDIT:
As an explanation, IEnumerable<T>
is simply an interface that represents "that which exposes an enumerator." A concrete implementation may well be some sort of in-memory list that does allow fast-access by index, or it may not. For instance, it could be a collection that cannot efficiently satisfy such a query, such as a linked-list (as mentioned by James Curran). It may even be no sort of in-memory data-structure at all, such as an iterator, where items are generated ('yielded') on demand, or by an enumerator that fetches the items from some remote data-source. Because IEnumerable<T>
must support all these cases, indexers are excluded from its definition.
You need "src/Hankees.txt"
Your file is in the source folder which is not counted as the working directory.\
Or you can move the file up to the root directory of your project and just use "Hankees.txt"
Your app is crashing at:
welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");
because mPlayer=null
.
You forgot to initialize Player mPlayer
in your PlayGame Activity.
mPlayer = new Player(context,"");
As also noted in the docs here.
Go to Python X.X/Lib
and add these lines to the site.py
there,
import sys
sys.path.append("yourpathstring")
This changes your sys.path
so that on every load, it will have that value in it..
As stated here about site.py
,
This module is automatically imported during initialization. Importing this module will append site-specific paths to the module search path and add a few builtins.
For other possible methods of adding some path to sys.path
see these docs
Well, it seems that the Content-Disposition header was originally created for e-mail, not the web. (Link to relevant RFC.)
I'm guessing that web browsers may respond to
Response.AppendHeader("content-disposition", "inline; filename=" + fileName);
when saving, but I'm not sure.
As detailed above, the generic List<> is the best way of doing it.
If you're stuck in .NET 1.*, then you will have to use the ArrayList class instead. This does not have compile-time type checking and you also have to add casting - messy.
Successive versions have also implemented various variations - including thread safe variants.
As others have pointed out, using the * operator for a mutable object duplicates references, so if you change one you change them all. If you want to create independent instances of a mutable object, your xrange syntax is the most Pythonic way to do this. If you are bothered by having a named variable that is never used, you can use the anonymous underscore variable.
[e for _ in xrange(n)]
For me, the simplest solution was to use the variable inside a (())
expression, as so:
if ((VAR > 0))
then
echo "$VAR is a positive integer."
fi
Of course, this solution is only valid if a value of zero doesn't make sense for your application. That happened to be true in my case, and this is much simpler than the other solutions.
As pointed out in the comments, this can make you subject to a code execution attack: The (( ))
operator evaluates VAR
, as stated in the Arithmetic Evaluation
section of the bash(1) man page. Therefore, you should not use this technique when the source of the contents of VAR
is uncertain (nor should you use ANY other form of variable expansion, of course).
Check out John Resig's pure JavaScript HTML parser.
EDIT: if you want the browser to parse the HTML for you, innerHTML
is exactly what you want. From this SO question:
var tempDiv = document.createElement('div');
tempDiv.innerHTML = htmlString;
You can use binding expressions:
private void ComboBox_Loaded(object sender, RoutedEventArgs e)
{
((ComboBox)sender).GetBindingExpression(ComboBox.ItemsSourceProperty)
.UpdateTarget();
}
But as Blindmeis noted you can also fire change notifications, further if your collection implements INotifyCollectionChanged
(for example implemented in the ObservableCollection<T>
) it will synchronize so you do not need to do any of this.
Couldn't you just pass the a name attribute and wrap it in a form?
<form id="form" action="do_stuff.php" method="post">
<select id="select_catalog" name="select_catalog_query">
<?php <<<INSERT THE SELECT OPTION LOOP>>> ?>
</select>
</form>
And then look for $_POST['select_catalog_query']
?
Just need click button 'AppTheme', and choose 'Manifest Themes'. It works in most cases.
One more jQuery solution
For a single stylesheet with id "css" try this:
$('#css').replaceWith('<link id="css" rel="stylesheet" href="css/main.css?t=' + Date.now() + '"></link>');
Wrap it in a function that has global scrope and you can use it from the Developer Console in Chrome or Firebug in Firefox:
var reloadCSS = function() {
$('#css').replaceWith('<link id="css" rel="stylesheet" href="css/main.css?t=' + Date.now() + '"></link>');
};
Remove pod name from Podfile
then
Open Terminal, set project folder path and
Run pod update
command.
NOTE: pod update
will update all the libraries to the latest version and will also remove those libraries whose name have been removed from podfile.
In general, you need to use FormatMessage
to convert from a Win32 error code to text.
From the MSDN documentation:
Formats a message string. The function requires a message definition as input. The message definition can come from a buffer passed into the function. It can come from a message table resource in an already-loaded module. Or the caller can ask the function to search the system's message table resource(s) for the message definition. The function finds the message definition in a message table resource based on a message identifier and a language identifier. The function copies the formatted message text to an output buffer, processing any embedded insert sequences if requested.
The declaration of FormatMessage:
DWORD WINAPI FormatMessage(
__in DWORD dwFlags,
__in_opt LPCVOID lpSource,
__in DWORD dwMessageId, // your error code
__in DWORD dwLanguageId,
__out LPTSTR lpBuffer,
__in DWORD nSize,
__in_opt va_list *Arguments
);
Here's a bit of a polyfill that leverages document.CurrentScript
if it exists and falls back to finding the script by ID.
<script id="uniqueScriptId">
(function () {
var thisScript = document.CurrentScript || document.getElementByID('uniqueScriptId');
// your code referencing thisScript here
());
</script>
If you include this at the top of every script tag I believe you'll be able to consistently know which script tag is being fired, and you'll also be able to reference the script tag in the context of an asynchronous callback.
Untested, so leave feedback for others if you try it.
You may find the solution in SQL User Defined Function to Parse a Delimited String helpful (from The Code Project).
You can use this simple logic:
Declare @products varchar(200) = '1|20|3|343|44|6|8765'
Declare @individual varchar(20) = null
WHILE LEN(@products) > 0
BEGIN
IF PATINDEX('%|%', @products) > 0
BEGIN
SET @individual = SUBSTRING(@products,
0,
PATINDEX('%|%', @products))
SELECT @individual
SET @products = SUBSTRING(@products,
LEN(@individual + '|') + 1,
LEN(@products))
END
ELSE
BEGIN
SET @individual = @products
SET @products = NULL
SELECT @individual
END
END

Look at all the issues surrounding trying to make divs perform like tables. They had to add table-xxx to mimic table layouts
Tables are supported and work very well in all browsers. Why ditch them? the fact that they had to mimic them is proof they did their job and well.
In my opinion use the best tool for the job and if you want tabulated data or something that resembles tabulated data tables just work.
Very Late reply I know but worth voicing.

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.
CN refers to class name, so put in your LDAP query CN=Users. Should work.
For the people like myself, who started recently: The loaders
keyword is replaced with rules
; even though it still represents the concept of loaders. So my webpack.config.js
, for a React app, is as follows:
var webpack = require('webpack');
var path = require('path');
var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');
var config = {
entry: APP_DIR + '/index.jsx',
output: {
path: BUILD_DIR,
filename: 'bundle.js'
},
module : {
rules : [
{
test : /\.jsx?/,
include : APP_DIR,
loader : 'babel-loader'
}
]
}
};
module.exports = config;
You cannot "convert" an existing column into an IDENTITY
column - you will have to create a new column as INT IDENTITY
:
ALTER TABLE ProductInProduct
ADD NewId INT IDENTITY (1, 1);
Update:
OK, so there is a way of converting an existing column to IDENTITY
. If you absolutely need this - check out this response by Martin Smith with all the gory details.
The error message clearly says that the default constructor has been deleted implicitly. It even says why: the class contains a non-static, const variable, which would not be initialized by the default ctor.
class X {
const int x;
};
Since X::x
is const
, it must be initialized -- but a default ctor wouldn't normally initialize it (because it's a POD type). Therefore, to get a default ctor, you need to define one yourself (and it must initialize x
). You can get the same kind of situation with a member that's a reference:
class X {
whatever &x;
};
It's probably worth noting that both of these will also disable implicit creation of an assignment operator as well, for essentially the same reason. The implicit assignment operator normally does members-wise assignment, but with a const member or reference member, it can't do that because the member can't be assigned. To make assignment work, you need to write your own assignment operator.
This is why a const
member should typically be static -- when you do an assignment, you can't assign the const member anyway. In a typical case all your instances are going to have the same value so they might as well share access to a single variable instead of having lots of copies of a variable that will all have the same value.
It is possible, of course, to create instances with different values though -- you (for example) pass a value when you create the object, so two different objects can have two different values. If, however, you try to do something like swapping them, the const member will retain its original value instead of being swapped.
1.) Create an arraylist of appropriate type, in this case i.e String
2.) Create a JSONObject
while passing your string to JSONObject
constructor as input
JSONObject
notation is represented by braces i.e {}
JSONArray
notation is represented by square brackets i.e []
3.) Retrieve JSONArray
from JSONObject
(created at 2nd step) using "interests"
as index.
4.) Traverse JASONArray
using loops upto the length of array provided by length()
function
5.) Retrieve your JSONObjects
from JSONArray
using getJSONObject(index)
function
6.) Fetch the data from JSONObject
using index '"interestKey"'.
Note : JSON
parsing uses the escape sequence for special nested characters if the json response (usually from other JSON response APIs) contains quotes ("
) like this
`"{"key":"value"}"`
should be like this
`"{\"key\":\"value\"}"`
so you can use JSONParser
to achieve escaped sequence format for safety as
JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(inputString);
Code :
JSONParser parser = new JSONParser();
String response = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";
JSONObject jsonObj = (JSONObject) parser.parse(response);
or
JSONObject jsonObj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");
List<String> interestList = new ArrayList<String>();
JSONArray jsonArray = jsonObj.getJSONArray("interests");
for(int i = 0 ; i < jsonArray.length() ; i++){
interestList.add(jsonArray.getJSONObject(i).optString("interestKey"));
}
Note : Sometime you may see some exceptions when the values are not available in appropriate type or is there is no mapping key
so in those cases when you are not sure about the presence of value so use optString
, optInt
, optBoolean
etc which will simply return the default value if it is not present and even try to convert value to int if it is of string type and vice-versa so Simply No null or NumberFormat exceptions at all in case of missing key or value
Get an optional string associated with a key. It returns the defaultValue if there is no such key.
public String optString(String key, String defaultValue) {
String missingKeyValue = json_data.optString("status","N/A");
// note there is no such key as "status" in response
// will return "N/A" if no key found
or To get empty string i.e ""
if no key found then simply use
String missingKeyValue = json_data.optString("status");
// will return "" if no key found where "" is an empty string

Stack memory is specifically the range of memory that is accessible via the Stack register of the CPU. The Stack was used as a way to implement the "Jump-Subroutine"-"Return" code pattern in assembly language, and also as a means to implement hardware-level interrupt handling. For instance, during an interrupt, the Stack was used to store various CPU registers, including Status (which indicates the results of an operation) and Program Counter (where was the CPU in the program when the interrupt occurred).
Stack memory is very much the consequence of usual CPU design. The speed of its allocation/deallocation is fast because it is strictly a last-in/first-out design. It is a simple matter of a move operation and a decrement/increment operation on the Stack register.
Heap memory was simply the memory that was left over after the program was loaded and the Stack memory was allocated. It may (or may not) include global variable space (it's a matter of convention).
Modern pre-emptive multitasking OS's with virtual memory and memory-mapped devices make the actual situation more complicated, but that's Stack vs Heap in a nutshell.
In Express 4.x
I used the following to load ejs
:
var path = require('path');
// Set the default templating engine to ejs
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
// The views/index.ejs exists in the app directory
app.get('/hello', function (req, res) {
res.render('index', {title: 'title'});
});
Then you just need two files to make it work - views/index.ejs
:
<%- include partials/navigation.ejs %>
And the views/partials/navigation.ejs
:
<ul><li class="active">...</li>...</ul>
You can also tell Express to use ejs
for html templates:
var path = require('path');
var EJS = require('ejs');
app.engine('html', EJS.renderFile);
// Set the default templating engine to ejs
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
// The views/index.html exists in the app directory
app.get('/hello', function (req, res) {
res.render('index.html', {title: 'title'});
});
Finally you can also use the ejs
layout module:
var EJSLayout = require('express-ejs-layouts');
app.use(EJSLayout);
This will use the views/layout.ejs
as your layout.
As other have said, you want to use either puts
or p
. Why? Is that magic?
Actually not. A rails console is, under the hood, an IRB, so all you can do in IRB you will be able to do in a rails console. Since for printing in an IRB we use puts
, we use the same command for printing in a rails console.
You can actually take a look at the console code in the rails source code. See the require of irb? :)

The Junction command line utility from SysInternals makes creating and deleting junctions easy.
My answer on how Singletons are bad is always, "they are hard to do right". Many of the foundational components of languages are singletons (classes, functions, namespaces and even operators), as are components in other aspects of computing (localhost, default route, virtual filesystem, etc.), and it is not by accident. While they cause trouble and frustration from time to time, they also can make a lot of things work a LOT better.
The two biggest screw ups I see are: treating it like a global & failing to define the Singleton closure.
Everyone talks about Singleton's as globals, because they basically are. However, much (sadly, not all) of the badness in a global comes not intrinsically from being global, but how you use it. Same goes for Singletons. Actually more so as "single instance" really doesn't need to mean "globally accessible". It is more a natural byproduct, and given all the bad that we know comes from it, we shouldn't be in such a hurry to exploit global accessibility. Once programmers see a Singleton they seem to always access it directly through its instance method. Instead, you should navigate to it just like you would any other object. Most code shouldn't even be aware it is dealing with a Singleton (loose coupling, right?). If only a small bit of code accesses the object like it is a global, a lot of harm is undone. I recommend enforcing it by restricting access to the instance function.
The Singleton context is also really important. The defining characteristic of a Singleton is that there is "only one", but the truth is it is "only one" within some kind of context/namespace. They are usually one of: one per thread, process, IP address or cluster, but can also be one per processor, machine, language namespace/class loader/whatever, subnet, Internet, etc.
The other, less common, mistake is to ignore the Singleton lifestyle. Just because there is only one doesn't mean a Singleton is some omnipotent "always was and always will be", nor is it generally desirable (objects without a begin and end violate all kinds of useful assumptions in code, and should be employed only in the most desperate of circumstances.
If you avoid those mistakes, Singletons can still be a PITA, bit it is ready to see a lot of the worst problems are significantly mitigated. Imagine a Java Singleton, that is explicitly defined as once per classloader (which means it needs a thread safety policy), with defined creation and destruction methods and a life cycle that dictates when and how they get invoked, and whose "instance" method has package protection so it is generally accessed through other, non-global objects. Still a potential source of trouble, but certainly much less trouble.
Sadly, rather than teaching good examples of how to do Singletons. We teach bad examples, let programmers run off using them for a while, and then tell them they are a bad design pattern.
Invert mask (XOR with ones), AND it with IP. Add 1. This will be the starting range. OR IP with mask. This will be the ending range.
You can use python's built-in function sum
sum
will return the sum of all the valueslen
to get list's lengthcode:
>>> list = [1,2,3,4]
>>> sum(list)
>>> 10
>>> len(list)
>>> 4
>>> avg = float(sum(list))/len(list)
>>> 2.5
>>>"""In pyton3 don't want to specify float"""
>>> 10 / 4
>>> 2.5
Use float because when using python 2.x, because:
int/int
returns int value (i.e. 2)float/int
returns float value (i.e. 2.5)While in Python 3.x:
int/int
return floatint//int
return intYou have chosen not only a realistic path, but arguably one of the best ecosystems strongly backed(also X-platforms) by MS. Still you should consider following points:

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.
The following res:
(resource) references need to point to your model.
<add name="Entities" connectionString="metadata=
res://*/Models.WraithNath.co.uk.csdl|
res://*/Models.WraithNath.co.uk.ssdl|
res://*/Models.WraithNath.co.uk.msl;
Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).
It also may help to specify the assembly rather than using "//*/".
Worst case, you can check everything (a bit slower but should always find the resource) by using
<add name="Entities" connectionString="metadata=
res://*/;provider= <!-- ... -->
It's quite simple:
if(new Date(fit_start_time) <= new Date(fit_end_time))
{//compare end <=, not >=
//your code here
}
Comparing 2 Date
instances will work just fine. It'll just call valueOf
implicitly, coercing the Date
instances to integers, which can be compared using all comparison operators. Well, to be 100% accurate: the Date
instances will be coerced to the Number
type, since JS doesn't know of integers or floats, they're all signed 64bit IEEE 754 double precision floating point numbers.

I tried all of the suggestions but was still unable to run msiexec.exe
with parameters that contained spaces. So my solution ended up using System.Diagnostics.ProcessStartInfo
:
# can have spaces here, no problems
$settings = @{
CONNECTION_STRING = "... ..."
ENTITY_CONTEXT = "... ..."
URL = "..."
}
$settingsJoined = ($settings.Keys | % { "$_=""$($settings[$_])""" }) -join " "
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.WorkingDirectory = $ScriptDirectory
$pinfo.FileName = "msiexec.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = "/l* install.log /i installer.msi $settingsJoined"
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$p.WaitForExit()
$stdout = $p.StandardOutput.ReadToEnd()
There are 4 main factors into why you would want to use synchronized
or java.util.concurrent.Lock
.
Note: Synchronized locking is what I mean when I say intrinsic locking.
When Java 5 came out with ReentrantLocks, they proved to have quite a noticeble throughput difference then intrinsic locking. If youre looking for faster locking mechanism and are running 1.5 consider j.u.c.ReentrantLock. Java 6's intrinsic locking is now comparable.
j.u.c.Lock has different mechanisms for locking. Lock interruptable - attempt to lock until the locking thread is interrupted; timed lock - attempt to lock for a certain amount of time and give up if you do not succeed; tryLock - attempt to lock, if some other thread is holding the lock give up. This all is included aside from the simple lock. Intrinsic locking only offers simple locking
You can use string.indexOf('a')
.
If the char a
is present in string
:
it returns the the index of the first occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
A duplicate in the database should be a 409 CONFLICT
.
I recommend using 422 UNPROCESSABLE ENTITY
for validation errors.
I give a longer explanation of 4xx codes here.

This is how you can use it in your activity:
CustomImageVIew mImageView = (CustomImageVIew)findViewById(R.id.customImageVIew1);
mImage.setBitmap(your bitmap);
And layout:

android:id="@+id/customImageVIew1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="15dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="15dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"

I use a similar technique to lazyload images, but can't help but notice that Javascript doesn't access the browser cache on first loading.
My example:
I have a rotating banner on my homepage with 4 images the slider wait 2 seconds, than the javascript loads the next image, waits 2 seconds, etc.
These images have unique urls that change whenever I modify them, so they get caching headers that will cache in the browser for a year.
max-age: 31536000, public
Now when I open Chrome Devtools and make sure de 'Disable cache' option is not active and load the page for the first time (after clearing the cache) all images get fetch and have a 200 status. After a full cycle of all images in the banner the network requests stop and the cached images are used.
Now when I do a regular refresh or go to a subpage and click back, the images that are in the cache seems to be ignored. I would expect to see a grey message "from disk cache" in the Network tab of Chrome devtools. In instead I see the requests pass by every two seconds with a Green status circle instead of gray, I see data being transferred, so it I get the impression the cache is not accessed at all from javascript. It simply fetches the image each time the page gets loaded.
So each request to the homepage triggers 4 requests regardless of the caching policy of the image.
Considering the above together and the new http2 standard most webservers and browsers now support, I think it's better to stop using lazyloading since http2 will load all images nearly simultaneously.
If this is a bug in Chrome Devtools it really surprises my nobody noticed this yet. ;)
If this is true, using lazyloading only increases bandwith usage.
Please correct me if I'm wrong. :)
You don't actually need to run a command from an xterm session, you can run it directly:
String[] arguments = new String[] {"/path/to/executable", "arg0", "arg1", "etc"};
Process proc = new ProcessBuilder(arguments).start();
If the process responds interactively to the input stream, and you want to inject values, then do what you did before:
OutputStream out = proc.getOutputStream();
out.write("command\n");
out.flush();
Don't forget the '\n' at the end though as most apps will use it to identify the end of a single command's input.
This code defines a function fixed_sum_digits
returning a generator enumerating all six digits numbers such that the sum of digits is 20.
def iter_fun(sum, deepness, myString, Total):
if deepness == 0:
if sum == Total:
yield myString
else:
for i in range(min(10, Total - sum + 1)):
yield from iter_fun(sum + i,deepness - 1,myString + str(i),Total)
def fixed_sum_digits(digits, Tot):
return iter_fun(0,digits,"",Tot)
Try to write it without yield from
. If you find an effective way to do it let me know.
I think that for cases like this one: visiting trees, yield from
makes the code simpler and cleaner.

For anyone else who wants to set Eclipse style goto definition, you need to create .sublime-mousemap
file in Sublime User
folder.
Windows - create Default (Windows).sublime-mousemap
in %appdata%\Sublime Text 3\Packages\User
Linux - create Default (Linux).sublime-mousemap
in ~/.config/sublime-text-3/Packages/User
Mac - create Default (OSX).sublime-mousemap
in ~/Library/Application Support/Sublime Text 3/Packages/User
Now open that file and put the following configuration inside
[
{
"button": "button1",
"count": 1,
"modifiers": ["ctrl"],
"press_command": "drag_select",
"command": "goto_definition"
}
]
You can change modifiers
key as you like.
Since Ctrl-button1
on Windows and Linux is used for multiple selections, adding a second modifier key like Alt might be a good idea if you want to use both features:
[
{
"button": "button1",
"count": 1,
"modifiers": ["ctrl", "alt"],
"press_command": "drag_select",
"command": "goto_definition"
}
]
Alternatively, you could use the right mouse button (button2
) with Ctrl alone, and not interfere with any built-in functions.

I had been struggling for 4 hours. the problem was in img tag. When you use square bracket to 'src' ex: [src]. you can not use this angular expression {{}}. you just give directly from an object example below. if you give angular expression {{}}. you will get interpolation error.
first i used ngFor to iterate the countries
*ngFor="let country of countries"
second you put this in the img tag. this is it.
<img [src]="sanitizer.bypassSecurityTrustResourceUrl(country.flag)"
height="20" width="20" alt=""/>
Instead of having your Test2 class contain a JPanel, you should have it subclass JPanel:
public class Test2 extends JPanel {
Test2(){
...
}
More details:
JPanel is a subclass of Component, so any method that takes a Component as an argument can also take a JPanel as an argument.
Older versions didn't let you add directly to a JFrame; you had to use JFrame.getContentPane().add(Component). If you're using an older version, this might also be an issue. Newer versions of Java do let you call JFrame.add(Component) directly.
Once I also got that same type of error.

Promise.all
is all or nothing. It resolves once all promises in the array resolve, or reject as soon as one of them rejects. In other words, it either resolves with an array of all resolved values, or rejects with a single error.
Some libraries have something called Promise.when
, which I understand would instead wait for all promises in the array to either resolve or reject, but I'm not familiar with it, and it's not in ES6.
Your code
I agree with others here that your fix should work. It should resolve with an array that may contain a mix of successful values and errors objects. It's unusual to pass error objects in the success-path but assuming your code is expecting them, I see no problem with it.
The only reason I can think of why it would "not resolve" is that it's failing in code you're not showing us and the reason you're not seeing any error message about this is because this promise chain is not terminated with a final catch (as far as what you're showing us anyway).
I've taken the liberty of factoring out the "existing chain" from your example and terminating the chain with a catch. This may not be right for you, but for people reading this, it's important to always either return or terminate chains, or potential errors, even coding errors, will get hidden (which is what I suspect happened here):
Promise.all(state.routes.map(function(route) {
return route.handler.promiseHandler().catch(function(err) {
return err;
});
}))
.then(function(arrayOfValuesOrErrors) {
// handling of my array containing values and/or errors.
})
.catch(function(err) {
console.log(err.message); // some coding error in handling happened
});

Update: 15th May, 2018:
The latest Windows 10 update (re-)activated the World Wide Web Publishing Service (in German: WWW-Publishingdienst). This might depend on the options you select during the configuration of the update you can make afterwards.
Update: 4th August, 2015:
If you have done clean installation of Windows 10, you may not have the Word Wide Web Publishing Service. In that case, simple WAMP/XAMPP installation should work fine.
If it doesn't, try installing Visual C++ Redistributable and then re-install WAMP/XAMPP.
I was facing a similar problem with WAMP. In Windows 10 TP, the Word Wide Web Publishing Service comes pre-installed. This is related to IIS and you can remove it if you don't need it.
This blocks the port 80
, making Apache act weirdly. You can do the following and try again.
This should make port 80 free and restarting WAMP/XAMPP should get you up and running!
There are other ways to do fix this. See Make WAMP Work On Windows 10.
ng-if on ng-include and on ng-controller will have a big impact matter on ng-include it will not load the required partial and does not process unless flag is true on ng-controller it will not load the controller unless flag is true but the problem is when a flag gets false in ng-if it will remove from DOM when flag gets true back it will reload the DOM in this case ng-show is better, for one time show ng-if is better
For ENOENT on Windows, https://github.com/nodejs/node-v0.x-archive/issues/2318#issuecomment-249355505 fix it.
e.g. replace spawn('npm', ['-v'], {stdio: 'inherit'}) with:
for all node.js version:
spawn(/^win/.test(process.platform) ? 'npm.cmd' : 'npm', ['-v'], {stdio: 'inherit'})
for node.js 5.x and later:
spawn('npm', ['-v'], {stdio: 'inherit', shell: true})
I found it easier to just take over the template from Bootstrap-ui. I have left the commented HTML still in-place to show what I changed.
Overwrite their default template:
<script type="text/ng-template" id="myDlgTemplateWrapper.html">
<div tabindex="-1" role="dialog" class="modal fade" ng-class="{in: animate}"
ng-style="{'z-index': 1050 + index*10, display: 'block'}" ng-click="close($event)">
<!-- <div class="modal-dialog"
ng-class="{'modal-sm': size == 'sm', 'modal-lg': size == 'lg'}"
>
<div class="modal-content" modal-transclude></div>
</div>-->
<div modal-transclude>
<!-- Your content goes here -->
</div>
</div>
</script>
Modify your dialog template (note the wrapper DIVs containing "modal-dialog" class and "modal-content" class):
<script type="text/ng-template" id="myModalContent.html">
<div class="modal-dialog {{extraDlgClass}}"
style="width: {{width}}; max-width: {{maxWidth}}; min-width: {{minWidth}}; ">
<div class="modal-content">
<div class="modal-header bg-primary">
<h3>I am a more flexible modal!</h3>
</div>
<div class="modal-body"
style="min-height: {{minHeight}}; height: {{height}}; max-height {{maxHeight}}; ">
<p>Make me any size you want</p>
</div>
<div class="modal-footer">
<button class="btn btn-primary" ng-click="ok()">OK</button>
<button class="btn btn-warning" ng-click="cancel()">Cancel</button>
</div>
</div>
</div>
</script>
And then call the modal with whatever CSS class or style parameters you wish to change (assuming you have already defined "app" somewhere else):
<script type="text/javascript">
app.controller("myTest", ["$scope", "$modal", function ($scope, $modal)
{
// Adjust these with your parameters as needed
$scope.extraDlgClass = undefined;
$scope.width = "70%";
$scope.height = "200px";
$scope.maxWidth = undefined;
$scope.maxHeight = undefined;
$scope.minWidth = undefined;
$scope.minHeight = undefined;
$scope.open = function ()

Now you can add whatever extra class you want, or simply change width/height sizes as necessary.
I further enclosed it within a wrapper directive, which is should be trivial from this point forward.

Just add xmlns:tools="http://schemas.android.com/tools"
to your manifest tag, and then you need to add tools:replace="android:icon"
before android:icon="@mipmap/ic_launcher"
.
I have a huge database with no (separate) index.
Any time I query by the primary key the results are, for all intensive purposes, instant.
A single tick represents one hundred nanoseconds or one ten-millionth of a second. FROM MSDN.
So 28 000 000 000 * 1/10 000 000 = 2 800 sec. 2 800 sec /60 = 46.6666min
Or you can do it programmaticly with TimeSpan:
static void Main()
{
TimeSpan ts = TimeSpan.FromTicks(28000000000);
double minutesFromTs = ts.TotalMinutes;
Console.WriteLine(minutesFromTs);
Console.Read();
}
Both give me 46 min and not 480 min...
Like Vito mentions, this error occurs after Java updates as the path:
C:\ProgramData\Oracle\Java\javapath
is added to the Path
environment variable, causing Eclipse to run using the wrong java version.
To fix the problem:
1) Right-click on Computer
and choose Properties
.
2) Click Advanced system settings
3) Click Environment Variables...
4) Find the Path
variable in the System variables
section.
5) Choose it and click Edit...
6) Find and delete the above mentioned path.
This fixed it for me. I should mention that I already have the path:
c:\Program Files\Java\jdk1.7.0_21\bin
in the Path
variable, but the new path was added to the beginning of the Path
variable and therefore resolution would use that path first.
I could do this in a JUnit Test Setup.
I wanted to test a Hibernate facade so I was looking for a generic way to do it. Note that the facade also implements a generic interface. Here T is the database class and U the primary key.
Ifacade<T,U>
is a facade to access the database object T with the primary key U.
public abstract class GenericJPAController<T, U, C extends IFacade<T,U>>
{

/* The properties definition is straightforward*/
protected T testObject;
protected C facadeManager;
@BeforeClass
public static void setUpClass() {
try {
emf = Persistence.createEntityManagerFactory("my entity manager factory");
} catch (Throwable ex) {
System.err.println("Failed to create sessionFactory object." + ex);
throw new ExceptionInInitializerError(ex);
}
}
@AfterClass
public static void tearDownClass() {
}
@Before
public void setUp() {
/* Get the class name*/
String className = ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[2].getTypeName();
/* Create the instance */
try {
facadeManager = (C) Class.forName(className).newInstance();
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException ex) {
Logger.getLogger(GenericJPAController.class.getName()).log(Level.SEVERE, null, ex);
}
createTestObject();
}
@After

Use a smarty template for your stuff then just set the POST array as a smarty array and open the template. In the template just echo out the array so if it passes:
if(correct){
header("Location: passed.php");
} else {
$smarty->assign("variables", $_POST);
$smarty->display("register_error.php");
exit;
}
I have not tried this yet but I am going to try it as a solution and will let you know what I find. But of course this method assumes that you are using smarty.
If not you can just recreate your form there on the error page and echo info into the form or you could send back non important data in a get from and get it
ex.
register.php?name=mr_jones&address==......
echo $_GET[name];
Just turn off notifications for the default sms app. Process your own notifications for all text messages!
Use an control flow library like after
after.map(array, function (value, done) {
// do something async
setTimeout(function () {
// do something with the value
done(null, value * 2)
}, 10)
}, function (err, mappedArray) {
// all done, continue here
console.log(mappedArray)
})
You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.
SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL
If you want to select a value as default, in your form builder give it a value :
this.myForm = this.FB.group({
mySelect: [this.options[0].key, [/* Validators here */]]
});
Now in your HTML :
<form [formGroup]="myForm">
<select [formControlName]="mySelect">
<option *ngFor="let opt of options" [value]="opt.key">ANY TEXT YOU WANT HERE</option>
</select>
</form>
What my code does is giving your select a value, that is equal to the first value of your options list. This is how you select an option as default in Angular, selected is useless.
notice, that code is:
std::abs((x - y)/x) <= epsilon
you are requiring that the "relative error" on the var is <= epsilon, not that the absolute difference is
On Windows use the Xampp shell (there is a 'Shell' button in your XAMPP control panel)
then
cd php\pear
to go to 'C:\xampp\php\pear'
then type
pear
<script>
$(document).ready(function(){
$(window).on('resize', function() {
jQuery("#grid").setGridWidth($('#fill').width(), false);
jQuery("#grid").setGridHeight($('#fill').height(),true);
}).trigger('resize');
});
</script>
If you are adding new foreign key to an existing table and the columns are not null and not assigned default value, you will get this error,
Either you need to make it nullable
or assign default value
, or delete all the existing records
to solve it.
In addition to the registers being used for mass operations, they are useful for their property of being preserved through a function call (call-preserved) in 32-bit calling convention. The ESI, EDI, EBX, EBP, ESP are call-preserved whereas EAX, ECX and EDX are not call-preserved. Call-preserved registers are respected by C library function and their values persist through the C library function calls.
Jeff Duntemann in his assembly language book has an example assembly code for printing the command line arguments. The code uses esi and edi to store counters as they will be unchanged by the C library function printf. For other registers like eax, ecx, edx, there is no guarantee of them not being used by the C library functions.
https://www.amazon.com/Assembly-Language-Step-Step-Programming/dp/0470497025
See section 12.8 How C sees Command-Line Arguments.
Note that 64-bit calling conventions are different from 32-bit calling conventions, and I am not sure if these registers are call-preserved or not.
Try the following:
javac file1.java file2.java
./main.go (in package main)
./a/a.go (in package a)
./a/b.go (in package a)
in this case:
main.go import "./a"
It can call the function in the a.go and b.go,that with first letter caps on.
I got the same error trying to execute flutter run on a mac. Apparently, in your flutter project, there is a file android/gradlew that is expected to be executable (and it wasn't). So in my case,
chmod a+rx android/gradlew
i used this command and execute the project
function abc() {
var color = document.getElementById("test").style.color;
if (color === "red")
document.getElementById("test").style.color="black";
else
document.getElementById("test").style.color="red";
}
There are several options available*:
*Disclaimer: This list may not be complete.
Using Flexbox
Nowadays, we can use flexbox. It is quite a handy alternative to the css-transform option. I would use this solution almost always. If it is just one element maybe not, but for example if I had to support an array of data e.g. rows and columns and I want them to be relatively centered in the very middle.
.flexbox {
display: flex;
height: 100px;
flex-flow: row wrap;
align-items: center;
justify-content: center;
background-color: #eaeaea;
border: 1px dotted #333;
}
.item {
/* default => flex: 0 1 auto */
background-color: #fff;
border: 1px dotted #333;
box-sizing: border-box;
}
_x000D_
<div class="flexbox">
<div class="item">I am centered in the middle.</div>
<div class="item">I am centered in the middle, too.</div>
</div>
_x000D_
Using CSS 2D-Transform
This is still a good option, was also the accepted solution back in 2015.
It is very slim and simple to apply and does not mess with the layouting of other elements.
.boxes {
position: relative;
}
.box {
position: relative;
display: inline-block;
float: left;
width: 200px;
height: 200px;
font-weight: bold;
color: #333;
margin-right: 10px;
margin-bottom: 10px;
background-color: #eaeaea;
}
.h-center {
text-align: center;
}
.v-center span {
position: absolute;
left: 0;
right: 0;
top: 50%;
transform: translate(0, -50%);
}
_x000D_
<div class="boxes">
<div class="box h-center">horizontally centered lorem ipsun dolor sit amet</div>
<div class="box v-center"><span>vertically centered lorem ipsun dolor sit amet lorem ipsun dolor sit amet</span></div>
<div class="box h-center v-center"><span>horizontally and vertically centered lorem ipsun dolor sit amet</span></div>
</div>
_x000D_
Note: This does also work with
:after
and:before
pseudo-elements.
Using Grid
This might just be an overkill, but it depends on your DOM. If you want to use grid anyway, then why not. It is very powerful alternative and you are really maximum flexible with the design.
Note: To align the items vertically we use flexbox in combination with grid. But we could also use
display: grid
on the items.
.grid {
display: grid;
width: 400px;
grid-template-rows: 100px;
grid-template-columns: 100px 100px 100px;
grid-gap: 3px;
align-items: center;
justify-content: center;
background-color: #eaeaea;
border: 1px dotted #333;
}
.item {
display: flex;
justify-content: center;
align-items: center;
border: 1px dotted #333;
box-sizing: border-box;
}
.item-large {
height: 80px;
}
_x000D_
<div class="grid">
<div class="item">Item 1</div>
<div class="item item-large">Item 2</div>
<div class="item">Item 3</div>
</div>

When filtering a DataFrame with string values, I find that the pyspark.sql.functions
lower
and upper
come in handy, if your data could have column entries like "foo" and "Foo":
import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))
You can use the method SelectTab
.
There are 3 versions:
public void SelectTab(int index);
public void SelectTab(string tabPageName);
public void SelectTab(TabPage tabPage);
(tomcat 7.0.32) I had problems to see debug messages althought was enabling TldLocationsCache row in tomcat/conf/logging.properties file. All I could see was a warning but not what libs were scanned. Changed every loglevel tried everything no luck. Then I went rogue debug mode (=remove one by one, clean install etc..) and finally found a reason.
My webapp had a customized tomcat/webapps/mywebapp/WEB-INF/classes/logging.properties file. I copied TldLocationsCache row to this file, finally I could see jars filenames.
# To see debug messages in TldLocationsCache, uncomment the following line: org.apache.jasper.compiler.TldLocationsCache.level = FINE
string name;
char *c_string;
getline(cin, name);
c_string = new char[name.length()];
for (int index = 0; index < name.length(); index++){
c_string[index] = name[index];
}
c_string[name.length()] = '\0';//add the null terminator at the end of
// the char array
I know this is not the predefined method but thought it may be useful to someone nevertheless.
The overhead is NOT due to the encryption. On a modern CPU, the encryption required by SSL is trivial.
The overhead is due to the SSL handshakes, which are lengthy and drastically increase the number of round-trips required for a HTTPS session over a HTTP one.
Measure (using a tool such as Firebug) the page load times while the server is on the end of a simulated high-latency link. Tools exist to simulate a high latency link - for Linux there is "netem". Compare HTTP with HTTPS on the same setup.
The latency can be mitigated to some extent by:
performSelector:withObject:afterDelay:
Since Symfony 3.3 you can use binding, like
services:
_defaults:
autowire: true
autoconfigure: true
bind:
$kernelProjectDir: '%kernel.project_dir%'
After that you can use parameter $kernelProjectDir in any controller OR service. Just like
class SomeControllerOrService
{
public function someAction(...., $kernelProjectDir)
{
.....
You need to make the members in the for the form class either public or, if the service class is in the same assembly, internal. Windows controls' visibility can be controlled through their Modifiers properties.
Note that it's generally considered a bad practice to explicitly tie a service class to a UI class. Rather you should create good interfaces between the service class and the form class. That said, for learning or just generally messing around, the earth won't spin off its axis if you expose form members for service classes.

If you need to set a delay of less than a second, it is not necessary to set the .seconds parameter. I hope this is useful to someone.
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: {
// your code hear
})
You'd use REGEXP_REPLACE
in order to remove all non-digit characters from a string:
select regexp_replace(column_name, '[^0-9]', '')
from mytable;
or
select regexp_replace(column_name, '[^[:digit:]]', '')
from mytable;
Of course you can write a function extract_number
. It seems a bit like overkill though, to write a funtion that consists of only one function call itself.
create function extract_number(in_number varchar2) return varchar2 is
begin
return regexp_replace(in_number, '[^[:digit:]]', '');
end;
ECMAScript 6 sets can permit faster computing of the elements of one array that aren't in the other:
const myArray = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
const toRemove = new Set(['b', 'c', 'g']);
const difference = myArray.filter( x => !toRemove.has(x) );
console.log(difference); // ["a", "d", "e", "f"]

Since the lookup complexity for the V8 engine browsers use these days is O(1), the time complexity of the whole algorithm is O(n).
way 1 :
Let we have java file test.java which contains main class testa now first we compile our java file simply as javac test.java we create file manifest.txt in same directory and we write Main-Class: mainclassname . e.g :
Main-Class: testa
then we create jar file by this command :
jar cvfm anyname.jar manifest.txt testa.class
then we run jar file by this command : java -jar anyname.jar
way 2 :
Let we have one package named one and every class are inside it. then we create jar file by this command :
jar cf anyname.jar one
then we open manifest.txt inside directory META-INF in anyname.jar file and write
Main-Class: one.mainclassname
in third line., then we run jar file by this command :
java -jar anyname.jar
to make jar file having more than one class file : jar cf anyname.jar one.class two.class three.class......
no , there is nothing similar IndexOf for Dictionary although you can make use of ContainsKey method to get whether a key belongs to dictionary or not
When working with fragments, instead of using this
or refering to the context, always use getActivity()
. You should call
getActivity().finish();
to finish your activity from fragment.
I upgraded from RC1 to RC5 and received this error.
I completed my migration (introducing a new app.module.ts
file, changing package.json
to include new versions and missing modules, and finally changing my main.ts
to boot accordingly, based on the Angular2 quick start example).
I did an npm update
and then an npm outdated
to confirm the versions installed were correct, still no luck.
I ended up completely wiping the node_modules
folder and reinstalling with npm install
- Voila! Problem solved.
Full process (Unix svn package):
Check files are not in SVN:

A folder
A folder/file1.txt
A folder/folder2
A folder/folder2/file2.txt
A folder/folderToIgnore
A folder/folderToIgnore/fileToIgnore1.txt

Reverted 'folderToIgnore'
Reverted 'folderToIgnore/fileToIgnore1.txt'
> svn revert fileToIgnore2.txt
Reverted 'fileToIgnore2.txt'
Edit svn ignore on folder
svn propedit svn:ignore .
Add two singles lines with just the following:

It's an ancient piece of code that I've used a few times:
if (parent.location.href == self.location.href) {
window.location.href = 'https://www.facebook.com/pagename?v=app_1357902468';
}
The problem sometimes occurs when there are errors in the project.
For instance, if your project is configured with a target of 3.2 but the 3.2 libraries are not available, you will not be able to change the version to 4.0!
The usual (perhaps brutal) solution I use is to create a new project with the correct target and copy src, res and manifest into the new project.
Update:
This seems to work:
I always run Android Tools | Fix Project Properties after making any changes to the build target.
AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.
As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.
So AArch64 and ARM64 refer to the same thing.
As many of the answer suggesting better solution is to use ArrayList. ArrayList size is not fixed and it is easily manageable.
It is resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list.
Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically.
Note that this implementation is not synchronized.
ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test1");
scripts.add("test2");
scripts.add("test3");
Often classes are used to enclose methods and following is the extension for answers above with default method in case the method is not found.

def p1(self):
print('Start')

"start": p1,

def call_it(self):

First .sql file converts into the UTF8.
Then use this command
mysql -p -u root --default_character_set utf8 test </var/201535.sql
---root is the username
---test is the database name
or
mysql -p -u root test < /var/201535.sql
---root is the username
---test is the database name
This is just like passing the error to the stdout or the terminal.
That is, cmd
is not a command:
$cmd 2>filename
cat filename
command not found
The error is sent to the file like this:
2>&1
Standard error is sent to the terminal.
To be certain that a folder exists (and not a file) I use this function:
Public Function FolderExists(strFolderPath As String) As Boolean
On Error Resume Next
FolderExists = ((GetAttr(strFolderPath) And vbDirectory) = vbDirectory)
On Error GoTo 0
End Function
It works both, with \
at the end and without.

calls a constructor defined in the parent class. The constructor may be defined in any parent class, but it will refer to the one overridden closest to the current class. Calls to other constructors in this way may only be done as the first line in a constructor.
Calling methods works the same way. Calling this.method()
calls a method defined in the current class where super.method()
will call the same method as defined in the parent class.

I just floated the title to the left and added a clear:both
div to the bottom..
Just for fun, here's another way:
;with counts as (
select CustomerName, EmailAddress,
count(*) over (partition by EmailAddress) as num
from Customers
)
select CustomerName, EmailAddress
from counts
where num > 1
Assuming you are generating a shared library, most probably what happens is that the variant of liblog4cplus.a
you are using wasn't compiled with -fPIC
. In linux, you can confirm this by extracting the object files from the static library and checking their relocations:
ar -x liblog4cplus.a
readelf --relocs fileappender.o | egrep '(GOT|PLT|JU?MP_SLOT)'
If the output is empty, then the static library is not position-independent and cannot be used to generate a shared object.
Since the static library contains object code which was already compiled, providing the -fPIC flag won't help.
You need to get ahold of a version of liblog4cplus.a
compiled with -fPIC
and use that one instead.
I did found a way to convert (even bad) html into well formed XML. I started to base this on the DOM loadHTML function. However during time several issues occurred and I optimized and added patches to correct side effects.
function tryToXml($dom,$content) {
if(!$content) return false;
// xml well formed content can be loaded as xml node tree
$fragment = $dom->createDocumentFragment();
// wonderfull appendXML to add an XML string directly into the node tree!
// aappendxml will fail on a xml declaration so manually skip this when occurred
if( substr( $content,0, 5) == '<?xml' ) {
$content = substr($content,strpos($content,'>')+1);
if( strpos($content,'<') ) {
$content = substr($content,strpos($content,'<'));
}
}
// if appendXML is not working then use below htmlToXml() for nasty html correction
if(!@$fragment->appendXML( $content )) {
return $this->htmlToXml($dom,$content);
}
return $fragment;
}
// convert content into xml
// dom is only needed to prepare the xml which will be returned
function htmlToXml($dom, $content, $needEncoding=false, $bodyOnly=true) {
// no xml when html is empty
if(!$content) return false;
// real content and possibly it needs encoding
if( $needEncoding ) {
// no need to convert character encoding as loadHTML will respect the content-type (only)
$content = '<meta http-equiv="Content-Type" content="text/html;charset='.$this->encoding.'">' . $content;
}
// return a dom from the content
$domInject = new DOMDocument("1.0", "UTF-8");
$domInject->preserveWhiteSpace = false;
$domInject->formatOutput = true;
// html type
try {
@$domInject->loadHTML( $content );
} catch(Exception $e){
// do nothing and continue as it's normal that warnings will occur on nasty HTML content
}
// to check encoding: echo $dom->encoding
$this->reworkDom( $domInject );
if( $bodyOnly ) {
$fragment = $dom->createDocumentFragment();
// retrieve nodes within /html/body
foreach( $domInject->documentElement->childNodes as $elementLevel1 ) {
if( $elementLevel1->nodeName == 'body' and $elementLevel1->nodeType == XML_ELEMENT_NODE ) {
foreach( $elementLevel1->childNodes as $elementInject ) {
$fragment->insertBefore( $dom->importNode($elementInject, true) );
}
}
}
} else {
$fragment = $dom->importNode($domInject->documentElement, true);
}
return $fragment;
}
protected function reworkDom( $node, $level = 0 ) {
// start with the first child node to iterate
$nodeChild = $node->firstChild;
while ( $nodeChild ) {
$nodeNextChild = $nodeChild->nextSibling;
switch ( $nodeChild->nodeType ) {
case XML_ELEMENT_NODE:
// iterate through children element nodes
$this->reworkDom( $nodeChild, $level + 1);
break;
case XML_TEXT_NODE:
case XML_CDATA_SECTION_NODE:
// do nothing with text, cdata
break;
case XML_COMMENT_NODE:
// ensure comments to remove - sign also follows the w3c guideline
$nodeChild->nodeValue = str_replace("-","_",$nodeChild->nodeValue);
break;
case XML_DOCUMENT_TYPE_NODE: // 10: needs to be removed
case XML_PI_NODE: // 7: remove PI
$node->removeChild( $nodeChild );
$nodeChild = null; // make null to test later
break;
case XML_DOCUMENT_NODE:
// should not appear as it's always the root, just to be complete
// however generate exception!
case XML_HTML_DOCUMENT_NODE:
// should not appear as it's always the root, just to be complete
// however generate exception!
default:
throw new exception("Engine: reworkDom type not declared [".$nodeChild->nodeType. "]");
}
$nodeChild = $nodeNextChild;
} ;
}
Now this also allows to add more html pieces into one XML which I needed to use myself. In general it can be used like this:
$c='<p>test<font>two</p>';
$dom=new DOMDocument('1.0', 'UTF-8');
$n=$dom->appendChild($dom->createElement('info')); // make a root element
if( $valueXml=tryToXml($dom,$c) ) {
$n->appendChild($valueXml);
}
echo '<pre/>'. htmlentities($dom->saveXml($n)). '</pre>';
In this example '<p>test<font>two</p>'
will nicely be outputed in well formed XML as '<info><p>test<font>two</font></p></info>
'. The info root tag is added as it will also allow to convert '<p>one</p><p>two</p>
' which is not XML as it has not one root element. However if you html does for sure have one root element then the extra root <info>
tag can be skipped.
With this I'm getting real nice XML out of unstructured and even corrupted HTML!
I hope it's a bit clear and might contribute to other people to use it.
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

as aside tip make sure your button is not subclass of any custom class in story board , in such a case your code best place should be in custom class it self cause code works only out of the custom class if your button is subclass of the default UIButton class and outlet of it , hope this may help anyone wonders why corner radios doesn't apply on my button from code .

I've had no issues committing a few files like this:
svn commit fileDir1/ fileDir2/ -m "updated!"
So I had this same problem with WSUS and it turned out that IIS 8.5 was not binding to my ipv4 ip address, but was binding to ipv6 address. when I accessed it via localhost:8580 it would translate it to the ipv6 localhost address, and thus would work. Accessing it via ip was a no go. I had to manually bind the address using netsh, then it worked right away. bloody annoying.
Steps:
netsh http add iplisten ipaddress (IPADDRESSOFYOURSERVER)
that's it. You should get:
IP address successfully added
I found the commands here https://serverfault.com/questions/123796/get-iis-7-5-to-listen-on-ipv6
All the solutions here are correct,but they are missing an important scenario in which the method Clear() is used, which doesn't provide OldItems
in the NotifyCollectionChangedEventArgs
object.
this is the perfect ObservableCollection
.
public delegate void ListedItemPropertyChangedEventHandler(IList SourceList, object Item, PropertyChangedEventArgs e);
public class ObservableCollectionEX<T> : ObservableCollection<T>
{
#region Constructors
public ObservableCollectionEX() : base()
{
CollectionChanged += ObservableCollection_CollectionChanged;
}
public ObservableCollectionEX(IEnumerable<T> c) : base(c)
{
CollectionChanged += ObservableCollection_CollectionChanged;
}
public ObservableCollectionEX(List<T> l) : base(l)
{
CollectionChanged += ObservableCollection_CollectionChanged;
}
#endregion
public new void Clear()
{
foreach (var item in this)
if (item is INotifyPropertyChanged i)
i.PropertyChanged -= Element_PropertyChanged;
base.Clear();
}
private void ObservableCollection_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
if (e.OldItems != null)
foreach (var item in e.OldItems)
if (item != null && item is INotifyPropertyChanged i)
i.PropertyChanged -= Element_PropertyChanged;
if (e.NewItems != null)
foreach (var item in e.NewItems)
if (item != null && item is INotifyPropertyChanged i)
{
i.PropertyChanged -= Element_PropertyChanged;
i.PropertyChanged += Element_PropertyChanged;
}
}
}
private void Element_PropertyChanged(object sender, PropertyChangedEventArgs e) => ItemPropertyChanged?.Invoke(this, sender, e);
public ListedItemPropertyChangedEventHandler ItemPropertyChanged;

Problem with alert boxes (especially sweet-alerts is that they have a delay and Selenium is pretty much too fast)
An Option that worked for me is:
while True:
try:
driver.find_element_by_xpath('//div[@class="sweet-alert showSweetAlert visible"]')
break
except:
wait = WebDriverWait(driver, 1000)
confirm_button = driver.find_element_by_xpath('//button[@class="confirm"]')
confirm_button.click()
SELECT count(*)
FROM information_schema.TABLES

I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:
[ServiceContract]
public interface IService1
{
[OperationContract]
[FaultContract(typeof(ServiceData))]
ForDataset GetCCDBdata();
[OperationContract]
[FaultContract(typeof(ServiceData))]
string GetCCDBdataasXMLstring();
//[OperationContract]
//string GetData(int value);
//[OperationContract]
//CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO: Add your service operations here
}
[DataContract]
public class ServiceData
{
[DataMember]
public bool Result { get; set; }
[DataMember]
public string ErrorMessage { get; set; }
[DataMember]
public string ErrorDetails { get; set; }
}
in your service1.svc.cs you can use this in the catch block:
catch (Exception ex)
{
myServiceData.Result = false;
myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
myServiceData.ErrorDetails = ex.ToString();
throw new FaultException<ServiceData>(myServiceData, ex.ToString());
}
And use this in the Client application like below code:
ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();
string str = obj.GetCCDBdataasXMLstring();
}
catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
{
Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
Console.ReadLine();
}
Just try this, it will help for sure to get the exact issue.
Another advantage of a singleton is that it can easily be serialized, which may be necessary if you need to save its state to disc, or send it somewhere remotely.
Do you want coordinates relative to the screen or the application?
If it's within the application just use:
Mouse.GetPosition(Application.Current.MainWindow);
If not, I believe you can add a reference to System.Windows.Forms
and use:
System.Windows.Forms.Control.MousePosition;
In python 3.x. you use
print("Hello, World")
In Python 2.x. you use
print "Hello, World!"
fopen()
will open a resource in the same directory as the file executing the command. In other words, if you're just running the file ~/test.php, your script will create ~/myText.txt.
This can get a little confusing if you're using any URL rewriting (such as in an MVC framework) as it will likely create the new file in whatever the directory contains the root index.php file.
Also, you must have correct permissions set and may want to test before writing to the file. The following would help you debug:
$fp = fopen("myText.txt","wb");
if( $fp == false ){
//do debugging or logging here
}else{
fwrite($fp,$content);
fclose($fp);
}
Based on Tom Gullen´s answer.
var start = new Date("02/05/2013");
var end = new Date("02/10/2013");
var loop = new Date(start);
while(loop <= end){
alert(loop);
var newDate = loop.setDate(loop.getDate() + 1);
loop = new Date(newDate);
}
In Jelly.core to test a literal string one would use:
<core:when test="${ name == 'ABC' }">
But if I have to check for string "Toy's R Us":
<core:when test="${ name == &quot;Toy's R Us&quot; }">
It would be like this, if the double quotes were allowed inside:
<core:when test="${ name == "Toy's R Us" }">
A combination of peoples post gave me the date and the time for excel conversion. I did return it as a string
def xldate_to_datetime(xldate):
tempDate = datetime.datetime(1900, 1, 1)
deltaDays = datetime.timedelta(days=int(xldate))
secs = (int((xldate%1)*86400)-60)
detlaSeconds = datetime.timedelta(seconds=secs)
TheTime = (tempDate + deltaDays + detlaSeconds )
return TheTime.strftime("%Y-%m-%d %H:%M:%S")
imageView.setLayoutParams
(new ViewGroup.MarginLayoutParams
(width, ViewGroup.LayoutParams.MATCH_PARENT));
The Type of layout params depends on the parent view group. If you put the wrong one it will cause exception.
Could you try something like this for example I think what you are wanting to utilize is the port.ReadExisting() Method
using System;
using System.IO.Ports;
class SerialPortProgram
{
// Create the serial port with basic settings
private SerialPort port = new SerialPort("COM1",
9600, Parity.None, 8, StopBits.One);
[STAThread]
static void Main(string[] args)
{
// Instatiate this
SerialPortProgram();
}
private static void SerialPortProgram()
{
Console.WriteLine("Incoming Data:");
// Attach a method to be called when there
// is data waiting in the port's buffer
port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
// Begin communications
port.Open();
// Enter an application loop to keep this thread alive
Console.ReadLine();
}
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// Show all the incoming data in the port's buffer
Console.WriteLine(port.ReadExisting());
}
}
Or is you want to do it based on what you were trying to do , you can try this
public class MySerialReader : IDisposable
{
private SerialPort serialPort;
private Queue<byte> recievedData = new Queue<byte>();
public MySerialReader()
{
serialPort = new SerialPort();
serialPort.Open();
serialPort.DataReceived += serialPort_DataReceived;
}
void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
{
byte[] data = new byte[serialPort.BytesToRead];
serialPort.Read(data, 0, data.Length);
data.ToList().ForEach(b => recievedData.Enqueue(b));
processData();
}
void processData()
{
// Determine if we have a "packet" in the queue
if (recievedData.Count > 50)
{
var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
}
}
public void Dispose()
{
if (serialPort != null)
{
serialPort.Dispose();
}
}
If you have a sufficiently large class that doesn't lend itself to effective refactoring, separating it into multiple files helps keep things organized.
For instance, if you have a database for a site containing a discussion forum and a products system, and you don't want to create two different providers classes (NOT the same thing as a proxy class, just to be clear), you can create a single partial class in different files, like
MyProvider.cs - core logic
MyProvider.Forum.cs - methods pertaining specifically to the forum
MyProvider.Product.cs - methods for products
It's just another way to keep things organized.
Also, as others have said, it's about the only way to add methods to a generated class without running the risk of having your additions destroyed the next time the class is regenerated. This comes in handy with template-generated (T4) code, ORMs, etc.

Following are the build-in constants you can use as per your requirements for getting the paths in Codeigniter:
EXT: The PHP file extension
FCPATH: Path to the front controller (this file) (root of CI)
SELF: The name of THIS file (index.php)
BASEPATH: Path to the system folder
APPPATH: The path to the “application” folder

jQuery 'fixes up' events to account for browser differences. When it does so, you can always access the 'native' event with event.originalEvent
(see the Special Properties subheading on this page).
Another option here is to have your iPhone connect via a proxy. Here's an example of how to do it with Fiddler (it's very easy):
http://conceptdev.blogspot.com/2009/01/monitoring-iphone-web-traffic-with.html
In that case any dns lookups your iPhone does will use the hosts file of the machine Fiddler is running on. Note, though, that you must use a name that will be resolved via DNS. example.local
, for instance, will not work. example.xyz
or example.dev
will.
The standard method to generate a number (without a utility method) in a range is to just use the double with the range:
long range = 1234567L;
Random r = new Random()
long number = (long)(r.nextDouble()*range);
will give you a long between 0 (inclusive) and range (exclusive). Similarly if you want a number between x and y:
long x = 1234567L;
long y = 23456789L;
Random r = new Random()
long number = x+((long)(r.nextDouble()*(y-x)));
will give you a long from 1234567 (inclusive) through 123456789 (exclusive)
Note: check parentheses, because casting to long has higher priority than multiplication.

I guess you have installed the 2.7 version manually, while 2.6 comes from a package?
The simple answer is: uninstall python package.
The more complex one is: do not install manually in /usr/local. Build a package with 2.7 version and then upgrade.
Package handling depends on what distribution you use.
I tried all the answers and nothing really worked for me.
So I've created my own method that compares simple java objects without going deep into nested structures...
Method returns null if all fields match or string containing mismatch details.
Only properties that have a getter method are compared.
How to use
assertNull(TestUtils.diff(obj1,obj2,ignore_field1, ignore_field2));
Sample output if there is a mismatch
Output shows property names and respective values of compared objects
alert_id(1:2), city(Moscow:London)
Code (Java 8 and above):
public static String diff(Object x1, Object x2, String ... ignored) throws Exception{
final StringBuilder response = new StringBuilder();
for (Method m:Arrays.stream(x1.getClass().getMethods()).filter(m->m.getName().startsWith("get")
&& m.getParameterCount()==0).collect(toList())){
final String field = m.getName().substring(3).toLowerCase();
if (Arrays.stream(ignored).map(x->x.toLowerCase()).noneMatch(ignoredField->ignoredField.equals(field))){
Object v1 = m.invoke(x1);
Object v2 = m.invoke(x2);
if ( (v1!=null && !v1.equals(v2)) || (v2!=null && !v2.equals(v1))){
response.append(field).append("(").append(v1).append(":").append(v2).append(")").append(", ");
}
}
}
return response.length()==0?null:response.substring(0,response.length()-2);

I would suggest separating your code based on the functionality and purpose specific to each sheet or module. In this manner, you would only put code relative to a sheet's UI inside the sheet's module and only put code related to modules in respective modules. Also, use separate modules to encapsulate code that is shared or reused among several different sheets.
For example, let's say you multiple sheets that are responsible for displaying data from a database in a special way. What kinds of functionality do we have in this situation? We have functionality related to each specific sheet, tasks related to getting data from the database, and tasks related to populating a sheet with data. In this case, I might start with a module for the data access, a module for populating a sheet with data, and within each sheet I'd have code for accessing code in those modules.
It might be laid out like this.
Module: DataAccess:
Function GetData(strTableName As String, strCondition1 As String) As Recordset
'Code Related to getting data from the database'
End Function
Module: PopulateSheet:
Sub PopulateASheet(wsSheet As Worksheet, rs As Recordset)
'Code to populate a worksheet '
End Function
Sheet: Sheet1 Code:
Sub GetDataAndPopulate()
'Sample Code'
Dim rs As New Recordset
Dim ws As Worksheet
Dim strParam As String
Set ws = ActiveSheet
strParam = ws.Range("A1").Value
Set rs = GetData("Orders",strParam)
PopulateASheet ws, rs
End Sub
Sub Button1_Click()
Call GetDataAndPopulate
End Sub
