Forgive me my ignorance (I'm still fairly new to Java and programming), but why wouldn't the above work?
I guess this doesn't solve the constant space issue... but it does at least get there in a reasonable time, correct? It will only take the space of the linked list plus the space of a set with n elements (where n is the number of elements in the linked list, or the number of elements until it reaches a loop). And for time, worst-case analysis, I think, would suggest O(nlog(n)). SortedSet look-ups for contains() are log(n) (check the javadoc, but I'm pretty sure TreeSet's underlying structure is TreeMap, whose in turn is a red-black tree), and in the worst case (no loops, or loop at very end), it will have to do n look-ups.
Came across with a fragment that contains multiple RecycleView so I only need one scrollbar instead of one scrollbar in each RecycleView.
So I just put the ScrollView in the parent container that contains the 2 RecycleViews and use android:isScrollContainer="false"
in the RecycleView
<android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layoutManager="LinearLayoutManager"
android:isScrollContainer="false" />
The sed
command
s/\(.\).\(.*\)/mv & \1\2/
means to replace:
\(.\).\(.*\)
with:
mv & \1\2
just like a regular sed
command. However, the parentheses, &
and \n
markers change it a little.
The search string matches (and remembers as pattern 1) the single character at the start, followed by a single character, follwed by the rest of the string (remembered as pattern 2).
In the replacement string, you can refer to these matched patterns to use them as part of the replacement. You can also refer to the whole matched portion as &
.
So what that sed
command is doing is creating a mv
command based on the original file (for the source) and character 1 and 3 onwards, effectively removing character 2 (for the destination). It will give you a series of lines along the following format:
mv F00001-0708-RG-biasliuyda F0001-0708-RG-biasliuyda
mv abcdef acdef
and so on.
In the Above,I found multiple solutions.But some solutions having a hanging issue or taking to much time in case of the port was not opened.Below solution worked for me :
import socket
def port_check(HOST):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(2) #Timeout in case of port not open
try:
s.connect((HOST, 22)) #Port ,Here 22 is port
return True
except:
return False
port_check("127.0.1.1")
import warnings
warnings.warn("Warning...........Message")
See the python documentation: here
The accepted answer needs an Option 3
ALSO Option 2 is TERRIBLE. It should NEVER be used (esp. in production) since it provides a FALSE sense of security. Just use HTTP instead of Option 2.

Extension to parse decimal number from string.
Ability to set decimal symbol manually.
public static class StringExtension
{
public static double DoubleParseAdvanced(this string strToParse, char decimalSymbol = ',')
{
string tmp = Regex.Match(strToParse, @"([-]?[0-9]+)([\s])?([0-9]+)?[." + decimalSymbol + "]?([0-9 ]+)?([0-9]+)?").Value;
if (tmp.Length > 0 && strToParse.Contains(tmp))
{
var currDecSeparator = System.Windows.Forms.Application.CurrentCulture.NumberFormat.NumberDecimalSeparator;
tmp = tmp.Replace(".", currDecSeparator).Replace(decimalSymbol.ToString(), currDecSeparator);
return double.Parse(tmp);
}
return 0;
}
}
How to use:
"It's 4.45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4,45 O'clock now".DoubleParseAdvanced(); // will return 4.45
"It's 4:45 O'clock now".DoubleParseAdvanced(':'); // will return 4.45
Get the invalid chars from System.IO.Path.GetInvalidPathChars();

Perfect, try it:
SELECT ROUTINE_DEFINITION FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_SCHEMA = 'yourdb' AND ROUTINE_TYPE = 'PROCEDURE' AND ROUTINE_NAME = "procedurename";
Do you mean this?
var listOfList = new List<List<int>>() {
new List<int>() { 1, 2 },
new List<int>() { 3, 4 },
new List<int>() { 5, 6 }
};
var list = new List<int> { 9, 9, 9 };
var result = list.Concat(listOfList.SelectMany(x => x));
foreach (var x in result) Console.WriteLine(x);
Results in: 9 9 9 1 2 3 4 5 6
There is no "standard place" for a sqlite database. The file's location is specified to the library, and may be in your home directory, in the invoking program's folder, or any other place.
If it helps, sqlite databases are, by convention, named with a .db
file extension.
Try this:
If Len(vValue & vbNullString) > 0 Then
' we have a non-Null and non-empty String value
doSomething()
Else
' We have a Null or empty string value
doSomethingElse()
End If
The PowerShell string evaluation is calling ToString() on the DataSet. In order to evaluate any properties (or method calls), you have to force evaluation by enclosing the expression in $()
for($i=0;$i -lt $ds.Tables[1].Rows.Count;$i++)
{
write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"
}
Additionally foreach
allows you to iterate through a collection or array without needing to figure out the length.
Rewritten (and edited for compile) -
foreach ($Row in $ds.Tables[1].Rows)
{
write-host "value is : $($Row[0])"
}
Utility git wizard https://github.com/makelinux/git-wizard counts separately unresolved conflicted changes (collisions) and unmerged files. Conflicts must be resolved manually or with mergetool. Resolved unmerged changes can me added and committed usually with git rebase --continue.
Code Snippet:
div{height: calc(100vh - 10vmax)}
"Segmentation fault" means that you tried to access memory that you do not have access to.
The first problem is with your arguments of main
. The main
function should be int main(int argc, char *argv[])
, and you should check that argc
is at least 2 before accessing argv[1]
.
Also, since you're passing in a float
to printf
(which, by the way, gets converted to a double
when passing to printf
), you should use the %f
format specifier. The %s
format specifier is for strings ('\0'
-terminated character arrays).
If it's like many other languages you may want to have a simple try:
i = 0;
if (0 == i++) // if true, increment happened after equality check
if (2 == ++i) // if true, increment happened before equality check
If the above doesn't happen like that, they may be equivalent
You can observer the progress of the download manager using LiveData and coroutines, see the gist below

Sharing my experience, how to import simple Netbeans java project into Eclipse workspace. Please follow the following steps:
Create .project file, inside the project folder at root level. Below code is the sample reference. Change your project name appropriately.
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>PROJECT_NAME</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
</buildSpec>
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
</projectDescription>
Now open Eclipse and follow the steps,
File > import > Existing Projects into Workspace > Select root directory > Finish
Now we need to correct the build path for proper compilation of src, by following these steps:
Right Click on project folder > Properties > Java Build Path > Click Source tab > Add Folder
(Add the correct src path from project and remove the incorrect ones). Find the image ref link how it looks.
LastOrDefault()
is usually not working but with the Tolist()
it will work. There is no need to use OrderByDescending
use Tolist()
like this.
GroupBy(p => p.Nws_ID).ToList().LastOrDefault();
It’s easy; just do the following:
rvm implode
or
rm -rf ~/.rvm
And don’t forget to remove the script calls in the following files:
~/.bashrc
~/.bash_profile
~/.profile
And maybe others depending on whatever shell you’re using.
You can also try this for the double quotes:
JSON.stringify(sDemoString).slice(1, -1);
JSON.stringify('my string with "quotes"').slice(1, -1);
Yes, you can merge them using HTML. When I create tables in .md
files from Github, I always like to use HTML code instead of markdown.
Github Flavored Markdown supports basic HTML in .md
file. So this would be the answer:
Markdown mixed with HTML:
| Tables | Are | Cool |
| ------------- |:-------------:| -----:|
| col 3 is | right-aligned | $1600 |
| col 2 is | centered | $12 |
| zebra stripes | are neat | $1 |
| <ul><li>item1</li><li>item2</li></ul>| See the list | from the first column|
Or pure HTML:
<table>
<tbody>
<tr>
<th>Tables</th>
<th align="center">Are</th>
<th align="right">Cool</th>
</tr>
<tr>
<td>col 3 is</td>
<td align="center">right-aligned</td>
<td align="right">$1600</td>
</tr>
<tr>
<td>col 2 is</td>
<td align="center">centered</td>
<td align="right">$12</td>
</tr>
<tr>
<td>zebra stripes</td>
<td align="center">are neat</td>
<td align="right">$1</td>
</tr>
<tr>
<td>
<ul>
<li>item1</li>
<li>item2</li>
</ul>
</td>
<td align="center">See the list</td>
<td align="right">from the first column</td>
</tr>
</tbody>
</table>
This is how it looks on Github:
You have a variety of problems. First, why are you using your specific @@FETCH_STATUS values? It should just be @@FETCH_STATUS = 0.
Second, you are not selecting your inner Cursor into anything. And I cannot think of any circumstance where you would select all fields in this way - spell them out!
Here's a sample to go by. Folder has a primary key of "ClientID" that is also a foreign key for Attend. I'm just printing all of the Attend UIDs, broken down by Folder ClientID:
Declare @ClientID int;
Declare @UID int;
DECLARE Cur1 CURSOR FOR
SELECT ClientID From Folder;
OPEN Cur1
FETCH NEXT FROM Cur1 INTO @ClientID;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'Processing ClientID: ' + Cast(@ClientID as Varchar);
DECLARE Cur2 CURSOR FOR
SELECT UID FROM Attend Where ClientID=@ClientID;
OPEN Cur2;
FETCH NEXT FROM Cur2 INTO @UID;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'Found UID: ' + Cast(@UID as Varchar);
FETCH NEXT FROM Cur2 INTO @UID;
END;
CLOSE Cur2;
DEALLOCATE Cur2;
FETCH NEXT FROM Cur1 INTO @ClientID;
END;
PRINT 'DONE';
CLOSE Cur1;
DEALLOCATE Cur1;
Finally, are you SURE you want to be doing something like this in a stored procedure? It is very easy to abuse stored procedures and often reflects problems in characterizing your problem. The sample I gave, for example, could be far more easily accomplished using standard select calls.
Here if you mention .getPath()
then that will return the path of Jar and I guess
you will need its parent to refer to all other config files placed with the jar.
This code works on Windows. Add the code within the main class.
File jarDir = new File(MyAppName.class.getProtectionDomain().getCodeSource().getLocation().getPath());
String jarDirpath = jarDir.getParent();
System.out.println(jarDirpath);
So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.
protected void onCreate(Bundle savedInstanceState) { setContentView(R.layout.my_layout); Bitmap bitmap = getIntent().getParcelableExtra("image"); ImageView imageView = (ImageView) findViewById(R.id.imageview); imageView.setImageBitmap(bitmap); }
Another solution (for side-by-side comparison as opposed to a unified view): https://github.com/danmysak/side-by-side.
What about sending a SIGSTOP to itself?
This should pause the process until SIGCONT is received. Which is in your case: never.
kill -STOP "$$";
# grace time for signal delivery
sleep 60;
You can use justify-content: space-between
in .test
like so:
.test {_x000D_
display: flex;_x000D_
justify-content: space-between;_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<div class="test">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>
_x000D_
For those who want to use Bootstrap 4 can use justify-content-between
:
div {_x000D_
width: 20rem;_x000D_
border: .1rem red solid;_x000D_
}
_x000D_
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet" />_x000D_
<div class="d-flex justify-content-between">_x000D_
<button>test</button>_x000D_
<button>test</button>_x000D_
</div>
_x000D_
You should use Android NDK to develop performance-critical portions of your apps in native code. See Android NDK.
Anyway i don't think it is the right way to develop an entire application.
In Swift 4:
Swift 4
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Your title"
}
I hope it helps, regards!
Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class
. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat
and DateTimeFormatterBuilder
.
DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);
final org.joda.time.LocalDate class
is an immutable datetime class representing a date without a time zone. LocalDate
is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.
Doesn't SELECT LEN(column_name)
work?
GZip is simply deflate plus a checksum and header/footer. Deflate is faster, though, as I learned the hard way.
Be careful while working with android contact list.
Reading contact list in above methods work on most android devices except HTC One and Sony Xperia. It wasted my six weeks trying to figure out what is wrong!
Most tutorials available online are almost similar - first read "ALL" contacts, then show in Listview
with ArrayAdapter
. This is not memory efficient solution. Instead of looking for solutions on other websites first, have a look at developer.android.com. If any solution is not available on developer.android.com you should look somewhere else.
The solution is to use CursorAdapter
instead of ArrayAdapter
for retrieving contact list. Using ArrayAdapter
would work on most devices, but it's not efficient. The CursorAdapter
retrieves only a portion of contact list at run time while the ListView
is being scrolled.
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
...
// Gets the ListView from the View list of the parent activity
mContactsList =
(ListView) getActivity().findViewById(R.layout.contact_list_view);
// Gets a CursorAdapter
mCursorAdapter = new SimpleCursorAdapter(
getActivity(),
R.layout.contact_list_item,
null,
FROM_COLUMNS, TO_IDS,
0);
// Sets the adapter for the ListView
mContactsList.setAdapter(mCursorAdapter);
}

In CSS3 there is a simple but brilliant hack for that:
font-size:calc(12px + 1.5vw);
This is because the static part of calc() defines the minimum. Even though the dynamic part might shrink to something near 0.

A workaround for Android 4.x:
I found AutoResizeTextView and it works great on my Android 2.1 emulator. I loved it so much. But unfortunately it failed on my own 4.0.4 cellphone and 4.1 emulator. After trying I found it could be easily resolved by adding following attributes in AutoResizeTextView class in the xml:
android:ellipsize="none"
android:singleLine="true"
With the 2 lines above, now AutoResizeTextView working perfectly on my 2.1 & 4.1 emulators and my own 4.0.4 cellphone now.
Hope this helps you. :-)
A lot of people create very strange responses to these questions that make alot more work than necessary.
The easiest way to do this consists of the following
In actual code, an example will be (combining all steps together):
var input = document.getElementById("input").value;
document.getElementById("output").value = JSON.stringify(JSON.parse(input),undefined,2);
output.value is going to be the area where you will want to display a beautified JSON.
An example statement that uses a sub-select :
select * into MyNewTable
from
(
select
*
from
[SomeOtherTablename]
where
EventStartDatetime >= '01/JAN/2018'
)
) mysourcedata
;
note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.
The database should reply with a message like: (9999 row(s) affected)
If Maven build works fine, try to synchronizing structure of Maven and IntelliJ IDEA projects.
In the Maven tool window, click refresh button . On pressing this button, IntelliJ IDEA parses the project structure in the Maven tool window.
Note that this might not help if you're using EAP build, since Maven synchronization feature may be broken sometimes.
Parameters are directly supported in MVC by simply adding parameters onto your action methods. Given an action like the following:
public ActionResult GetImages(string artistName, string apiKey)
MVC will auto-populate the parameters when given a URL like:
/Artist/GetImages/?artistName=cher&apiKey=XXX
One additional special case is parameters named "id". Any parameter named ID can be put into the path rather than the querystring, so something like:
public ActionResult GetImages(string id, string apiKey)
would be populated correctly with a URL like the following:
/Artist/GetImages/cher?apiKey=XXX
In addition, if you have more complicated scenarios, you can customize the routing rules that MVC uses to locate an action. Your global.asax file contains routing rules that can be customized. By default the rule looks like this:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
If you wanted to support a url like
/Artist/GetImages/cher/api-key
you could add a route like:
routes.MapRoute(
"ArtistImages", // Route name
"{controller}/{action}/{artistName}/{apikey}", // URL with parameters
new { controller = "Home", action = "Index", artistName = "", apikey = "" } // Parameter defaults
);
and a method like the first example above.

Please notice that this is the officially supported by Apple, so there's no need of jailbroken devices or testing on the simulator, but you'll have to use Xcode 7 (currently in beta by the time of this post) or later.
I successfully deployed an app to my iPhone without a developer account. You'll have to use your iCloud account to solve the provisioning profile issues. Just add your iCloud account and assign it in the Team dropdown (in the Identity menu) and the Fix Issue button should do the rest.
UPDATE:
Some people are having problems with iOS 8.4, here is how to fix it.
Copy this method into your class
public int getArrayIndex(int[] arr,int value) {
int k=0;
for(int i=0;i<arr.length;i++){
if(arr[i]==value){
k=i;
break;
}
}
return k;
}
Call this method with pass two perameters Array and value and store its return value in a integer variable.
int indexNum = getArrayIndex(array,value);
Thank you
In order to assign these to variables, be sure not to add spaces in front or after the equals sign:
set filepath=%~dp1
set filename=%~nx1
Then you should have no issues.
Drawable myDrawable = getResources().getDrawable(R.drawable.logo);
Bitmap myLogo = ((BitmapDrawable) myDrawable).getBitmap();
Since API 22 getResources().getDrawable()
is deprecated, so we can use following solution.
Drawable vectorDrawable = VectorDrawableCompat.create(getResources(), R.drawable.logo, getContext().getTheme());
Bitmap myLogo = ((BitmapDrawable) vectorDrawable).getBitmap();
Let's say you have a shiny Foo class. Well you have 3 options:
1) You want to use the method (or attribute) of a class inside the definition of that class:
class Foo(object):
attribute1 = 1 # class attribute (those don't use 'self' in declaration)
def __init__(self):
self.attribute2 = 2 # instance attribute (those are accessible via first
# parameter of the method, usually called 'self'
# which will contain nothing but the instance itself)
def set_attribute3(self, value):
self.attribute3 = value
def sum_1and2(self):
return self.attribute1 + self.attribute2
2) You want to use the method (or attribute) of a class outside the definition of that class
def get_legendary_attribute1():
return Foo.attribute1
def get_legendary_attribute2():
return Foo.attribute2
def get_legendary_attribute1_from(cls):
return cls.attribute1
get_legendary_attribute1() # >>> 1
get_legendary_attribute2() # >>> AttributeError: type object 'Foo' has no attribute 'attribute2'
get_legendary_attribute1_from(Foo) # >>> 1
3) You want to use the method (or attribute) of an instantiated class:
f = Foo()
f.attribute1 # >>> 1
f.attribute2 # >>> 2
f.attribute3 # >>> AttributeError: 'Foo' object has no attribute 'attribute3'
f.set_attribute3(3)
f.attribute3 # >>> 3

The keyword exists, but it is not implemented.
The only good reason to use goto that I can think of is this:
for (int i = 0; i < MAX_I; i++) {
for (int j = 0; j < MAX_J; j++) {
// do stuff
goto outsideloops; // to break out of both loops
}
}
outsideloops:
In Java you can do this like this:
loops:
for (int i = 0; i < MAX_I; i++) {
for (int j = 0; j < MAX_J; j++) {
// do stuff
break loops;
}
}

I solved this case by using static Action
public class CatalogoModel
{
private String _Id;
private String _Descripcion;
private Boolean _IsChecked;
public String Id
{
get { return _Id; }
set { _Id = value; }
}
public String Descripcion
{
get { return _Descripcion; }
set { _Descripcion = value; }
}
public Boolean IsChecked
{
get { return _IsChecked; }
set
{
_IsChecked = value;
NotifyPropertyChanged("IsChecked");
OnItemChecked.Invoke();
}
}
public static Action OnItemChecked;
}
public class ReglaViewModel : ViewModelBase
{
private ObservableCollection<CatalogoModel> _origenes;
CatalogoModel.OnItemChecked = () =>
{
var x = Origenes.Count; //Entra cada vez que cambia algo en _origenes
};
}
here is what you should put
local stringnumber = "10"
local a = tonumber(stringnumber)
print(a + 10)
output:

As an alternative you may want to check out BridgeIt at bridgeit.mobi. Open source, it has resolved the browser performance / consistency issue discussed above in that it leverages the standard browser on the device vs. the web-view browser. It also allows you to access the native features without having to worry about app store deployments and/or native containers.
I've used if for simple camera based access and scanner access and it works well for simple apps. Documentation is a bit light. Not sure how it would do on more complex apps.
That command did not work for me, I used:
$ export PATH="$PATH:/c/Python27"
Then to make sure that git remembers the python path every time you open git type the following.
echo 'export PATH="$PATH:/c/Python27"' > .profile
The correct way to do it would be:
adb -s 123abc12 shell getprop
Which will give you a list of all available properties and their values. Once you know which property you want, you can give the name as an argument to getprop
to access its value directly, like this:
adb -s 123abc12 shell getprop ro.product.model
The details in adb devices -l
consist of the following three properties: ro.product.name
, ro.product.model
and ro.product.device
.
Note that ADB shell ends lines with \r\n
, which depending on your platform might or might not make it more difficult to access the exact value (e.g. instead of Nexus 7
you might get Nexus 7\r
).
There really isn't any way of doing this as most of the useful information is discarded in the compilation process. However, you may want to take a look at this site to see if you can find some way of extracting something from the DLL.
$("#myTable").offset().top;
This will give you the computed offset (relative to document) of any object.
Declare them outside the subroutines, like this:
Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine
End Sub
Sub OtherSubRoutine()
MsgBox wbA.Name, vbInformation
End Sub
Alternately, you can pass variables between subroutines:
Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
Set wbA = Workbooks.Open("C:\file.xlsx")
Set wbB = Workbooks.Open("C:\file2.xlsx")
OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
MsgBox wb1.Name, vbInformation
MsgBox wb2.Name, vbInformation
End Sub
Or use Functions
to return values:
Sub MySubroutine()
Dim i as Long
i = MyFunction()
MsgBox i
End Sub
Function MyFunction()
'Lots of code that does something
Dim x As Integer, y as Double
For x = 1 to 1000
'Lots of code that does something
Next
MyFunction = y
End Function
In the second method, within the scope of OtherSubRoutine
you refer to them by their parameter names wb1
and wb2
. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.
A Note About User Forms
Personally I would recommend keeping Option Explicit
in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn
when you meant lCount
etc., among other reasons).
If you're using Option Explicit
(which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public
scoped variables, as these are not "public" in the same sense. For instance, i
is undefined, though it's Public
in the scope of UserForm1
:
You can refer to it as UserForm1.i
to avoid the compile error, or since forms are New
-able, you can create a variable object to contain reference to your form, and refer to it that way:
NB: In the above screenshots x
is declared Public x as Long
in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x
to avoid ambiguity and possible shadowing in case you re-use variable names...
Both Redirect::to()
and Redirect::away()
should work.
Difference
Redirect::to() does additional URL checks and generations. Those additional steps are done in Illuminate\Routing\UrlGenerator and do the following, if the passed URL is not a fully valid URL (even with protocol):
Determines if URL is secure rawurlencode() the URL trim() URL

Use html instead of append:
$.get("banner.html", function(data){
$(this).children("div:first").html(data);
});
.success()
only gets called if your webserver responds with a 200 OK HTTP header - basically when everything is fine.
The callbacks attached to done() will be fired when the deferred is resolved. The callbacks attached to fail() will be fired when the deferred is rejected.
promise.done(doneCallback).fail(failCallback)
.done() has only one callback and it is the success callback
You have to implement your own comparison function that will compare the dictionaries by values of name keys. See Sorting Mini-HOW TO from PythonInfo Wiki
Those who prefer to use laravel helpers they can check if a request is ajax using laravel request()
helper.

From the sed
man page:
Normally, sed cyclically copies a line of input, not including its terminating newline character, into a pattern space, (unless there is something left after a "D" function), applies all of the commands with addresses that select that pattern space, copies the pattern space to the standard output, appending a newline, and deletes the pattern space.
It's operating on the line without the newline present, so the pattern you have there can't ever match. You need to do something else - like match against $
(end-of-line) or ^
(start-of-line).
Here's an example of something that worked for me:
$ cat > states
California
Massachusetts
Arizona
$ sed -e 's/$/\
> /' states
California
Massachusetts
Arizona
I typed a literal newline character after the \
in the sed
line.
In the html tables, <table>
tag expect <tr>
tag right after itself and <tr>
tag expect <td>
tag right after itself. So if you want to put a div in table, you can put it in between <td>
and </td>
tags as data.
<table>_x000D_
<tr>_x000D_
<td>_x000D_
<div>_x000D_
<p>It works well</p>_x000D_
</div>_x000D_
</td>_x000D_
</tr>_x000D_
<table>
_x000D_
You could create a custom tag as such:
<html>
<head>
<style>
vr {
display: inline-block;
// This is where you'd set the ruler color
background-color: black;
// This is where you'd set the ruler width
width: 2px;
//this is where you'd set the spacing between the ruler and surrounding text
margin: 0px 5px 0px 5px;
height: 100%;
vertical-align: top;
}
</style>
</head>
<body>
this is text <vr></vr> more text
</body>
</html>
(If anyone knows a way that I could turn this into an "open-ended" tag, like <hr>
let me know and I will edit it in)
It occurs when you don't specify the no of parameters the __init__()
or any other method looking for.
For example:
class Dog:
def __init__(self):
print("IN INIT METHOD")
def __unicode__(self,):
print("IN UNICODE METHOD")
def __str__(self):
print("IN STR METHOD")
obj=Dog("JIMMY",1,2,3,"WOOF")
When you run the above programme, it gives you an error like that:
TypeError: __init__() takes 1 positional argument but 6 were given
How we can get rid of this thing?
Just pass the parameters, what __init__()
method looking for
class Dog:
def __init__(self, dogname, dob_d, dob_m, dob_y, dogSpeakText):
self.name_of_dog = dogname
self.date_of_birth = dob_d
self.month_of_birth = dob_m
self.year_of_birth = dob_y
self.sound_it_make = dogSpeakText
def __unicode__(self, ):
print("IN UNICODE METHOD")
def __str__(self):
print("IN STR METHOD")
obj = Dog("JIMMY", 1, 2, 3, "WOOF")
print(id(obj))
I have always just installed the new version on top and never had any issues. Do make sure that your path is updated to point to the new version though.
As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished
, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog
in your operation's dealloc
method and confirm that's getting called.
You said:
I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit
The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self
, or even just references an instance variable of self
, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation
subclass is released.
For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.
If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation
is getting deallocated). A common example is the use of a repeating NSTimer
. Or some custom delegate
or other object that is erroneously maintaining a strong
reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:
Or in Xcode 5:
All of the solutions work partially, and even below probably does not cover all of the cases. My issue was in trying to insert a string into a utf8 mysql table. The string (and its bytes) all conformed to utf8, but had several bad sequences. I assume that most of them were control or formatting.
function clean_string($string) {
$s = trim($string);
$s = iconv("UTF-8", "UTF-8//IGNORE", $s); // drop all non utf-8 characters
// this is some bad utf-8 byte sequence that makes mysql complain - control and formatting i think
$s = preg_replace('/(?>[\x00-\x1F]|\xC2[\x80-\x9F]|\xE2[\x80-\x8F]{2}|\xE2\x80[\xA4-\xA8]|\xE2\x81[\x9F-\xAF])/', ' ', $s);
$s = preg_replace('/\s+/', ' ', $s); // reduce all multiple whitespace to a single space
return $s;
}
To further exacerbate the problem is the table vs. server vs. connection vs. rendering of the content, as talked about a little here

This is not an answer, but it's hard to read if I put results in comment.
I get these results with a Mac Pro (Westmere 6-Cores Xeon 3.33 GHz). I compiled it with clang -O3 -msse4 -lstdc++ a.cpp -o a
(-O2 get same result).
uint64_t size=atol(argv[1])<<20;
unsigned 41950110000 0.811198 sec 12.9263 GB/s
uint64_t 41950110000 0.622884 sec 16.8342 GB/s
uint64_t size=1<<20;
unsigned 41950110000 0.623406 sec 16.8201 GB/s
uint64_t 41950110000 0.623685 sec 16.8126 GB/s
I also tried to:
for
statement in reverse: for (uint64_t i=size/8;i>0;i-=4)
. This gives the same result and proves the compile is smart enough to not divide size by 8 every iteration (as expected).Here is my wild guess:
The speed factor comes in three parts:
code cache: uint64_t
version has larger code size, but this does not have an effect on my Xeon CPU. This makes the 64-bit version slower.
Instructions used. Note not only the loop count, but the buffer is accessed with a 32-bit and 64-bit index on the two versions. Accessing a pointer with a 64-bit offset requests a dedicated 64-bit register and addressing, while you can use immediate for a 32-bit offset. This may make the 32-bit version faster.
Instructions are only emitted on the 64-bit compile (that is, prefetch). This makes 64-bit faster.
The three factors together match with the observed seemingly conflicting results.
The answers did help, but I think a full implementation of this will help a lot of people.

To iterate through the keys of an object, use a for .. in
loop:
for (var key in json_obj) {
if (json_obj.hasOwnProperty(key)) {
// do something with `key'
}
}
To test all elements for empty children, you can use a recursive approach: iterate through all elements and recursively test their children too.
Removing a property of an object can be done by using the delete
keyword:
var someObj = {
"one": 123,
"two": 345
};
var key = "one";
delete someObj[key];
console.log(someObj); // prints { "two": 345 }

I think some code about the cURL solution is needed here, so I will share mine (it was written mixing several sources as the PHP Manual and comments).
It does some parallel HTTP requests (domains in $aURLs
) and print the responses once each one is completed (and stored them in $done
for other possible uses).
The code is longer than needed because the realtime print part and the excess of comments, but feel free to edit the answer to improve it:

Your query would always return an empty recordset since cut_name= '?????' and cut_name='??'
will never evaluate to true
.
In general, INTERSECT
in MySQL
should be emulated like this:
SELECT *
FROM mytable m
WHERE EXISTS
(
SELECT NULL
FROM othertable o
WHERE (o.col1 = m.col1 OR (m.col1 IS NULL AND o.col1 IS NULL))
AND (o.col2 = m.col2 OR (m.col2 IS NULL AND o.col2 IS NULL))
AND (o.col3 = m.col3 OR (m.col3 IS NULL AND o.col3 IS NULL))
)
If both your tables have columns marked as NOT NULL
, you can omit the IS NULL
parts and rewrite the query with a slightly more efficient IN
:
SELECT *
FROM mytable m
WHERE (col1, col2, col3) IN
(
SELECT col1, col2, col3
FROM othertable o
)
$(document).ready(function() {
$("#form1").validate({

You are also you using type="button". And I'm not sure why you ought to separate the submit button, place it within the form. It's more proper to do it that way. This should work.
When you see them spelled out in requirements they tend to include:
Inner and outer joins are a must but i rarely ever see it mentioned in requirements. And it's surprising how many so-called db professionals cannot get their head around a simple outer join.
To just get the simple list of folders without full path, you can use:
Directory.GetDirectories(parentDirectory).Select(d => Path.GetRelativePath(parentDirectory, d)
Its defined in RFC 2045 as a special padding character if fewer than 24 bits are available at the end of the encoded data.
You have to copy in Users/user/.p2 and .eclipse from old location when it come from and older location. For example i made a copy from computer to another, and i had this error, then i copied those folders and it worked !
For completeness:
Along the lines of Chase's answer, I usually use as.data.frame
to coerce the matrix to a data.frame:
m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))
EDIT: speed test data.frame
vs. as.data.frame
system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
user system elapsed
8.005 0.108 8.165
system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
user system elapsed
3.759 0.048 3.802
Yes, it appears to be faster (by about 2 times).
To make an app with NO status bars,

That's all there is to it.
I solved the error by changing the port for the project.
I did the following steps:
Good luck!
Use:
if (function_exists('curl_file_create')) { // php 5.5+
$cFile = curl_file_create($file_name_with_full_path);
} else { //
$cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);
You can also refer:
http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/
Important hint for PHP 5.5+:
Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
This worked for me under Windows 10 x64

Ensure that the Python directories are in the path, e.g.:
# Edit Environment variables so that variable "path" points to the new location.
# Insert these at the start of the list (or delete other Python directories), as Windows takes the first match it finds.
# Run the program "Edit the System Environment Variables".
# Or see Control Panel under "System Properties".
S:\Research\bin\Python375\Scripts\
S:\Research\bin\Python375\
Then:
python -m pip install --upgrade --force-reinstall pip
In my particular case, the error was caused by shifting the Python directory to a new location.
In my case the below method works.
sed -i 's/playstation/PS4/' input.txt
Can be written as:
sed -i 's/playstation/PS4\nplaystation/' input.txt
PS4
playstation
Consider using \\n while using it in a string literal.
sed : is stream editor
-i : Allows to edit the source file
+: Is delimiter.
I hope the above information works for you .
Following up on @Bruno Bronosky and @mrteatime, I offer the suggestion that you just write your boolean return "backwards". This is what I mean:
foo()
{
if [ "$1" == "bar" ]; then
true; return
else
false; return
fi;
}
That eliminates the ugly two line requirement for every return statement.

You really need to look at the state part of the error message to find the root cause of the issue.
2, 5 = Invalid userid
6 = Attempt to use a Windows login name with SQL Authentication
7 = Login disabled and password mismatch
8 = Password mismatch
9 = Invalid password
11, 12 = Valid login but server access failure
13 = SQL Server service paused
18 = Change password required
Afterwards, Google how to fix the issue.
my problem was that we had this set in web.config
<httpCookies httpOnlyCookies="true" requireSSL="true" />
this means that when debugging in non-SSL (the default), the auth cookie would not get sent back to the server. this would mean that the server would send a new auth cookie (with a new session) for every request back to the client.
the fix is to either set requiressl to false in web.config and true in web.release.config or turn on SSL while debugging:
There's a Babel plugin that allows you to write conditional statements inside JSX without needing to escape them with JavaScript or write a wrapper class. It's called JSX Control Statements:
<View style={styles.container}>
<If condition={ this.state == 'news' }>
<Text>data</Text>
</If>
</View>
It takes a bit of setting up depending on your Babel configuration, but you don't have to import anything and it has all the advantages of conditional rendering without leaving JSX which leaves your code looking very clean.
Have you had a look over at RegExLib?
Entering US phone number brought back quite a list of possibilities.
What's so confusing about it... getters are functions that are called when you get a property, setters, when you set it. example, if you do
obj.prop = "abc";
You're setting the property prop, if you're using getters/setters, then the setter function will be called, with "abc" as an argument. The setter function definition inside the object would ideally look something like this:
set prop(var) {
// do stuff with var...
}
I'm not sure how well that is implemented across browsers. It seems Firefox also has an alternative syntax, with double-underscored special ("magic") methods. As usual Internet Explorer does not support any of this.
The original question concerns infinity. So, why not use
#define Infinity ((double)(42 / 0.0))
according to the IEEE definition? You can negate that of course.

But in my case I have enabled 2 types of session in my web.config file
It's like below.
First one :
<modules runAllManagedModulesForAllRequests="true">
<remove name="Session" />
<add name="Session" type="System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>
Second one :
<sessionState mode="Custom" customProvider="DefaultSessionProvider">
<providers>
<add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="PawLoyalty" applicationName="PawLoyalty"/>
</providers>
</sessionState>
So in my case I have to comment Second one.B'cos that thing for the production.When I commented out second one my problem vanished.
On Python 3 numpy.genfromtxt

The XP Support Tools (which can be installed from your XP CD) come with a program called setx.exe
:
C:\Program Files\Support Tools>setx /?
SETX: This program is used to set values in the environment
of the machine or currently logged on user using one of three modes.
1) Command Line Mode: setx variable value [-m]
Optional Switches:
-m Set value in the Machine environment. Default is User.
...
For more information and example use: SETX -i
I think Windows 7 actually comes with setx
as part of a standard install.

See the thumbnail function of PIL's Image Module. You can use it to save smaller versions of files as various filetypes and if you're wanting to preserve as much quality as you can, consider using the ANTIALIAS
filter when you do.
Other than that, I'm not sure if there's a way to specify a maximum desired size. You could, of course, write a function that might try saving multiple versions of the file at varying qualities until a certain size is met, discarding the rest and giving you the image you wanted.
My approach. Tricky, but works well for me

Unlike other methods presented here, this bit of code will not cause the browser to display a warning asking the user if he wants to leave; instead, it exploits the evented nature of the DOM to redirect back to the current page (and thus cancel navigation) before the browser has a chance to unload it from memory.
Since it works by short-circuiting navigation directly, it cannot be used to prevent the page from being closed; however, it can be used to disable frame-busting.
(function () {
var location = window.document.location;
var preventNavigation = function () {
var originalHashValue = location.hash;
window.setTimeout(function () {
location.hash = 'preventNavigation' + ~~ (9999 * Math.random());
location.hash = originalHashValue;
}, 0);
};
window.addEventListener('beforeunload', preventNavigation, false);
window.addEventListener('unload', preventNavigation, false);
})();
Disclaimer: You should never do this. If a page has frame-busting code on it, please respect the wishes of the author.
From RFC 2616:
HTTP communication usually takes place over TCP/IP connections. The default port is TCP 80, but other ports can be used. This does not preclude HTTP from being implemented on top of any other protocol on the Internet, or on other networks. HTTP only presumes a reliable transport; any protocol that provides such guarantees can be used; the mapping of the HTTP/1.1 request and response structures onto the transport data units of the protocol in question is outside the scope of this specification.
So although it doesn't explicitly say so, UDP is not used because it is not a "reliable transport".
EDIT - more recently, the QUIC protocol (which is more strictly a pseudo-transport or a session layer protocol) does use UDP for carrying HTTP/2.0 traffic and much of Google's traffic already uses this protocol. It's currently progressing towards standardisation as HTTP/3.
The new version of SharePoint and Office (SharePoint 2010 and Office 2010) respectively are supposed to allow for this. This also includes the web based versions. I have seen Word and Excel in action do this, not sure about other client applications.
I am not sure about the specific implementation features you are asking about in terms of security though. Sorry.,=
Here is a discussion
http://blogs.msdn.com/b/sharepoint/archive/2009/10/19/sharepoint-2010.aspx
You might consider referencing the actual date/time in the source column for Quote_Month
, then you could transform your OR
into a couple of AND
s, something like (assuing the date's in something I've chosen to call Quote_Date
)
=SUMIFS(Quote_Value,"<=90",Quote_Date,">="&DATE(2013,11,1),Quote_Date,"<="&DATE(2013,12,31),Salesman,"=JBloggs",Days_To_Close)
(I moved the interesting conditions to the front).
This approach works here because that "OR" condition is actually specifying a date range - it might not work in other cases.
Alternate solution
Create a column that will store the month:
data['month'] = data['date'].dt.month
Create a column that will store the year:
data['year'] = data['date'].dt.year
You've almost done it. However setting flex: 0 0 <basis>
declaration to the columns would prevent them from growing/shrinking; And the <basis>
parameter would define the width of columns.
In addition, you could use CSS3 calc()
expression to specify the height
of columns with the respect to the height of the header.
#productShowcaseTitle {
flex: 0 0 100%; /* Let it fill the entire space horizontally */
height: 100px;
}
#productShowcaseDetail,
#productShowcaseThumbnailContainer {
height: calc(100% - 100px); /* excluding the height of the header */
}
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-flow: row wrap;_x000D_
_x000D_
height: 600px;_x000D_
width: 580px;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
flex: 0 0 100%; /* Let it fill the entire space horizontally */_x000D_
height: 100px;_x000D_
background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
flex: 0 0 66%; /* ~ 2 * 33.33% */_x000D_
height: calc(100% - 100px); /* excluding the height of the header */_x000D_
background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
flex: 0 0 34%; /* ~ 33.33% */_x000D_
height: calc(100% - 100px); /* excluding the height of the header */_x000D_
background-color: black;_x000D_
}
_x000D_
<div id="productShowcaseContainer">_x000D_

<div id="productShowcaseDetail"></div>_x000D_
<div id="productShowcaseThumbnailContainer"></div>_x000D_
</div>
_x000D_
(Vendor prefixes omitted due to brevity)
Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div>
element, it would be achieved without using calc()
as follows:
<div class="contentContainer"> <!-- Added wrapper -->
<div id="productShowcaseDetail"></div>
<div id="productShowcaseThumbnailContainer"></div>
</div>
#productShowcaseContainer {
display: flex;
flex-direction: column;
height: 600px; width: 580px;
}
.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-direction: column;_x000D_
_x000D_
height: 600px;_x000D_
width: 580px;_x000D_
}_x000D_
_x000D_
.contentContainer {_x000D_
display: flex;_x000D_
flex: 1;_x000D_
}_x000D_
_x000D_
#productShowcaseTitle {_x000D_
height: 100px;_x000D_
background-color: silver;_x000D_
}_x000D_
_x000D_
#productShowcaseDetail {_x000D_
flex: 3;_x000D_
background-color: lightgray;_x000D_
}_x000D_
_x000D_
#productShowcaseThumbnailContainer {_x000D_
flex: 2;_x000D_
background-color: black;_x000D_
}
_x000D_
<div id="productShowcaseContainer">_x000D_
<div id="productShowcaseTitle"></div>_x000D_
_x000D_
<div class="contentContainer"> <!-- Added wrapper -->_x000D_

The bash script solution:
if ! xset q &>/dev/null; then
echo "No X server at \$DISPLAY [$DISPLAY]" >&2
exit 1
fi
Doesn't work if you login from another console (Ctrl+Alt+F?) or ssh. For me this solution works in my Archlinux:
#!/bin/sh
ps aux|grep -v grep|grep "/usr/lib/Xorg"
EXITSTATUS=$?
if [ $EXITSTATUS -eq 0 ]; then
echo "X server running"
exit 1
fi
You can change /usr/lib/Xorg for only Xorg or the proper command on your system.
While there's no way to connect to multiple servers as different users in a single instance of SSMS, what you're looking for is the following RUNAS syntax:
runas /netonly /user:domain\username program.exe
When you use the "/netonly" switch, you can log in using remote credentials on a domain that you're not currently a member of, even if there's no trust set up. It just tells runas that the credentials will be used for accessing remote resources - the application interacts with the local computer as the currently logged-in user, and interacts with remote computers as the user whose credentials you've given.
You'd still have to run multiple instances of SSMS, but at least you could connect as different windows users in each one.
runas /netonly /user:domain\username ssms.exe

For those who are searching for a light answer, you can get a simple working example from here:
html {
position: relative;
min-height: 100%;
}
body {
margin-bottom: 60px /* Height of the footer */
}
footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px /* Example value */
}
Just play with the body
's margin-bottom
for adding space between the content and footer.

You set DockPanel.Dock="Top" to the StackPanel, but the StackPanel is not a child of the DockPanel... the Border is. Your docking property is being ignored.
If you move DockPanel.Dock="Top" to the Border instead, both of your problems will be fixed :)
Join on one-to-many relation in JPQL looks as follows:
select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName
When several properties are specified in select
clause, result is returned as Object[]
:
Object[] temp = (Object[]) em.createNamedQuery("...")
.setParameter("groupName", groupName)
.getSingleResult();
String fname = (String) temp[0];
String lname = (String) temp[1];
By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table
to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:
@Entity @Table(name = "Users")
public class User implements Serializable { ... }
I've found a way to validate a modalpopup without a postback.
In the ModalPopupExtender I set the OnOkScript to a function e.g ValidateBeforePostBack(), then in the function I call Page_ClientValidate for the validation group I want, do a check and if it fails, keep the modalpopup showing. If it passes, I call __doPostBack
.
function ValidateBeforePostBack(){
Page_ClientValidate('MyValidationGroupName');
if (Page_IsValid) { __doPostBack('',''); }
else { $find('mpeBehaviourID').show(); }
}
There are three parts:
You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:
#!path/to/interpretter
To find the path to your python interpretter on your machine you can run the command:
which python
This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:
#!/usr/bin/python
You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:
chmod +x myscript.py
The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:
echo $PATH
This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:
which <commandname>
Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:
export PATH=/my/directory/with/pythonscript:$PATH
Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile
Store a reference to the meter instance as a member in Production:
public class Production {
//The other members, properties etc...
private Meter m;
Production(Meter m) {
this.m = m;
}
}
And then in the Meter-class:
public class Meter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production(this);
}
}
Also note that you need to implement an accessor method/property so that the Production class can actually access the powerRating member of the Meter class.
use the below code please :
Properties p = new Properties();
StringBuffer path = new StringBuffer("com/al/common/email/templates/");
path.append("foo.properties");
InputStream fs = getClass().getClassLoader()
.getResourceAsStream(path.toString());
if(fs == null){
System.err.println("Unable to load the properties file");
}
else{
try{
p.load(fs);
}
catch (IOException e) {
e.printStackTrace();
}
}
Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.
a = 5
makes the variable name a
to refer to the integer 5. Later, a = "hello"
makes the variable name a
to refer to a string containing "hello". Static typed languages would have you declare int a
and then a = 5
, but assigning a = "hello"
would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a
refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.a = "5"
(the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5
to get "hello5"
.Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...
With PHP 5.6 on Amazon Linux (should be the same on RedHat or CentOS):
yum install php56-opcache
and then restart apache.
There is nothing available that I'm aware of. The next best thing would be to simply have one script execute another via CLI, but that's a bit rudimentary. Depending on what you are trying to do and how complex it is, this may or may not be an option.
Solution is in target="_blank" like this:
http://www.ozzu.com/website-design-forum/multiple-form-submit-actions-t25024.html
edit form like this:
<form method="post" action="../booking/step1.php" onsubmit="doubleSubmit(this)">
And use this script:
<script type="text/javascript">
<!--
function doubleSubmit(f)
{
// submit to action in form
f.submit();
// set second action and submit
f.target="_blank";
f.action="../booking/vytvor.php";
f.submit();
return false;
}
//-->
</script>
Something I noticed was that I had "other_database" and "Other_Database" in my databases. That caused this problem as I actually had same reference in other database which caused this mysterious error!
The logic is wrong. Consider this:
x = ["a","b","c"]
x[0] // "a"
x["0"] // "a"
0 in x // true
"0" in x // true
x.hasOwnProperty(0) // true
x.hasOwnProperty("0") // true
There is no reason to loop to check for key (or indices for arrays) existence. Now, values are a different story...
Happy coding
I've been trying to do something very similar but not using the nodes. However, my xml structure is a little different.
You have it like this:
<Metrics>
<Metric id="TransactionCleanupThread.RefundOldTrans" type="timer" ...>
If it were like this instead:
<Metrics>
<Metric>
<id>TransactionCleanupThread.RefundOldTrans</id>
<type>timer</type>
.
.
.
Then you could simply use this SQL statement.
SELECT
Sqm.SqmId,
Data.value('(/Sqm/Metrics/Metric/id)[1]', 'varchar(max)') as id,
Data.value('(/Sqm/Metrics/Metric/type)[1]', 'varchar(max)') AS type,
Data.value('(/Sqm/Metrics/Metric/unit)[1]', 'varchar(max)') AS unit,
Data.value('(/Sqm/Metrics/Metric/sum)[1]', 'varchar(max)') AS sum,
Data.value('(/Sqm/Metrics/Metric/count)[1]', 'varchar(max)') AS count,
Data.value('(/Sqm/Metrics/Metric/minValue)[1]', 'varchar(max)') AS minValue,
Data.value('(/Sqm/Metrics/Metric/maxValue)[1]', 'varchar(max)') AS maxValue,
Data.value('(/Sqm/Metrics/Metric/stdDeviation)[1]', 'varchar(max)') AS stdDeviation,
FROM Sqm
To me this is much less confusing than using the outer apply or cross apply.
I hope this helps someone else looking for a simpler solution!
The beauty of jQuery would allow us to do the following:
$(function()
{
var benefits = $('#benefits');
// this is the show function
$('a[name=1]').click(function()
{
benefits.show();
});
// this is the hide function
$('a', benefits).click(function()
{
benefits.hide();
});
});
Alternatively you could have 1 button toggle the display, like this:
$(function()
{
// this is the show and hide function, all in 1!
$('a[name=1]').click(function()
{
$('#benefits').toggle();
});
});
Character set conversion is done implicitly on the database connection level. You can force automatic conversion off in the ODBC or ADODB connection string with the parameter "Auto Translate=False". This is NOT recommended. See: https://msdn.microsoft.com/en-us/library/ms130822.aspx
There has been a codepage incompatibility in SQL Server 2005 when Database and Client codepage did not match. https://support.microsoft.com/kb/KbView/904803
SQL-Management Console 2008 and upwards is a UNICODE application. All values entered or requested are interpreted as such on the application level. Conversation to and from the column collation is done implicitly. You can verify this with:
SELECT CAST(N'±' as varbinary(10)) AS Result
This will return 0xB100
which is the Unicode character U+00B1 (as entered in the Management Console window). You cannot turn off "Auto Translate" for Management Studio.
If you specify a different collation in the select, you eventually end up in a double conversion (with possible data loss) as long as "Auto Translate" is still active. The original character is first transformed to the new collation during the select, which in turn gets "Auto Translated" to the "proper" application codepage. That's why your various COLLATION tests still show all the same result.
You can verify that specifying the collation DOES have an effect in the select, if you cast the result as VARBINARY
instead of VARCHAR
so the SQL Server transformation is not invalidated by the client before it is presented:
SELECT cast(columnName COLLATE SQL_Latin1_General_CP850_BIN2 as varbinary(10)) from tableName
SELECT cast(columnName COLLATE SQL_Latin1_General_CP1_CI_AS as varbinary(10)) from tableName
This will get you 0xF1
or 0xB1
respectively if columnName
contains just the character '±'
You still might get the correct result and yet a wrong character, if the font you are using does not provide the proper glyph.
Please double check the actual internal representation of your character by casting the query to VARBINARY
on a proper sample and verify whether this code indeed corresponds to the defined database collation SQL_Latin1_General_CP850_BIN2
SELECT CAST(columnName as varbinary(10)) from tableName
Differences in application collation and database collation might go unnoticed as long as the conversion is always done the same way in and out. Troubles emerge as soon as you add a client with a different collation. Then you might find that the internal conversion is unable to match the characters correctly.
All that said, you should keep in mind that Management Studio usually is not the final reference when interpreting result sets. Even if it looks gibberish in MS, it still might be the correct output. The question is whether the records show up correctly in your applications.
Just Modified the previous example to print even collection containing user defined objects.

print sorted(['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue'])
\d is a digit, + is 1 or more, so a sequence of 1 or more digits
I do understand, that your question was about files stored in MEDIA_ROOT, but sometimes it can be possible to store content in static, when you are not planning to create content of that type anymore.
May be this is a rare case, but anyway - if you have a huge amount of "pictures of the day" for your site - and all these files are on your hard drive?
In that case I see no contra to store such a content in STATIC.
And all becomes really simple:
static
To link to static files that are saved in STATIC_ROOT Django ships with a static template tag. You can use this regardless if you're using RequestContext or not.
{% load static %} <img src="{% static "images/hi.jpg" %}" alt="Hi!" />
copied from Official django 1.4 documentation / Built-in template tags and filters
There's two options:
Log Navigator (command-7 or view|navigators|log) and select your debug session.
"View | Show Debug Area" to view the NSLog output and interact with the debugger.
Here's a pic with both on. You wouldn't normally have both on, but I can only link one image per post! http://i.stack.imgur.com/4gG4P.png
Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..
FROM TABLE A
The other way is
FROM (SELECT col as name1, col2 as name2 FROM ...) B
Notice that the select clause and the parentheses around it are a table, a virtual table.
So, using your second code example (I am guessing at the columns you are hoping to retrieve here):
SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
Notice that your real table attribute
is the first table in this join, and that this virtual table I've called b
is the second table.
This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.
SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
SELECT count(*) AS langcount, at.attribute
FROM attributeTranslation at
GROUP BY at.attribute
) c ON (a.id = c.attribute)
See how that goes? You've generated a virtual table c
containing two columns, joined it to the other two, used one of the columns for the ON
clause, and returned the other as a column in your result set.
Write Console.ReadKey();

Conclusion. It barely matters.
Premature optimization is the root of all evil.
Swift 5+:
let globalPoint = aView.superview?.convert(aView.frame.origin, to: nil)
You're probably just getting a stack overflow here. The array is too big to fit in your program's stack address space.
If you allocate the array on the heap you should be fine, assuming your machine has enough memory.
int* array = new int[1000000];
But remember that this will require you to delete[]
the array. A better solution would be to use std::vector<int>
and resize it to 1000000 elements.
your string is NOT a valid json to start with.
a valid json will be,
{
"area": [
{
"area": "kothrud"
},
{
"area": "katraj"
}
]
}
if you do a json_decode
, it will yield,
stdClass Object
(
[area] => Array
(
[0] => stdClass Object
(
[area] => kothrud
)
[1] => stdClass Object
(
[area] => katraj
)
)
)
Update: to use
$string = '
{
"area": [
{
"area": "kothrud"
},
{
"area": "katraj"
}
]
}
';
$area = json_decode($string, true);
foreach($area['area'] as $i => $v)
{
echo $v['area'].'<br/>';
}
Output:
kothrud
katraj
Update #2:
for that true
:
When TRUE, returned objects will be converted into associative arrays. for more information, click here
As of Android versions M and N, following works for me and would be the correct approach. Emptying the ListView or setting the Adapter to null is not the right approach and would lead to null pointer issue, invalid ListView and/or crash of the app.
Simply do:
mList.clear();
mAdapter.notifyDataSetChanged();
i.e. first you clear the list altogether, and then let the adapter know about this change. Android will take care of correctly updating the UI with an empty list. In my case, my list is an ArrayList.
In case you are doing this operation from a different thread, run this code on the UI thread:
runOnUiThread(mRunnable);
Where mRunnable would be:
Runnable mRunnable = new Runnable() {
public void run() {
mList.clear();
mAdapter.notifyDataSetChanged();
}
};;
FORCE_INDEX
is going to be deprecated after MySQL 8:
Thus, you should expect USE INDEX, FORCE INDEX, and IGNORE INDEX to be deprecated in
a future release of MySQL, and at some time thereafter to be removed altogether.
https://dev.mysql.com/doc/refman/8.0/en/index-hints.html
You should be using JOIN_INDEX
, GROUP_INDEX
, ORDER_INDEX
, and INDEX
instead, for v8.
In my case it was an issue of the PHP version.
The .phar file I was using was not compatible with PHP 5.3.9. Switching interpreter to PHP 7 did fix it.
In Eclipse, there is one more feature in the dependencyManagement
. When dependencies
is used without it, the unfound dependencies are noticed in the pom file. If dependencyManagement
is used, the unsolved dependencies remain unnoticed in the pom file and errors appear only in the java files. (imports and such...)
Yet another option is to cast the XML as nvarchar, and then search for the given string as if the XML vas a nvarchar field.
SELECT *
FROM Table
WHERE CAST(Column as nvarchar(max)) LIKE '%TEST%'
I love this solution as it is clean, easy to remember, hard to mess up, and can be used as a part of a where clause.
EDIT: As Cliff mentions it, you could use:
...nvarchar if there's characters that don't convert to varchar
To add to add to the previous answer, there is even a fourth way that can be used
import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)
export class Car {
id: number;
make: string;
model: string;
color: string;
year: Date;
constructor(car) {
{
this.id = car.id;
this.make = car.make || '';
this.model = car.model || '';
this.color = car.color || '';
this.year = new Date(car.year).getYear();
}
}
}
The || can become super useful for very complex data objects to default data that doesn't exist.
. .
In your component.ts or service.ts file you can deserialize response data into the model:
// Import the car model
import { Car } from './car.model.ts';
// If single object
car = new Car(someObject);
// If array of cars
cars = someDataToDeserialize.map(c => new Car(c));
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(10 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
// ...
});
The dispatch_after(_:_:_:)
function takes three parameters:
a delay
a dispatch queue
a block or closure
The dispatch_after(_:_:_:)
function invokes the block or closure on the dispatch queue that is passed to the function after a given delay. Note that the delay is created using the dispatch_time(_:_:)
function. Remember this because we also use this function in Swift.
I recommend to go through the tutorial Raywenderlich Dispatch tutorial

Since the large post above covers many different SQL approaches for Postgres versions (not only non-9.5 as in the question), I would like to add how to do it in SQLAlchemy if you are using Postgres 9.5. Instead of implementing your own upsert, you can also use SQLAlchemy's functions (which were added in SQLAlchemy 1.1). Personally, I would recommend using these, if possible. Not only because of convenience, but also because it lets PostgreSQL handle any race conditions that might occur.
Cross-posting from another answer I gave yesterday (https://stackoverflow.com/a/44395983/2156909)
SQLAlchemy supports ON CONFLICT
now with two methods on_conflict_do_update()
and on_conflict_do_nothing()
:
Copying from the documentation:
from sqlalchemy.dialects.postgresql import insert
stmt = insert(my_table).values(user_email='[email protected]', data='inserted data')
stmt = stmt.on_conflict_do_update(
index_elements=[my_table.c.user_email],
index_where=my_table.c.user_email.like('%@gmail.com'),
set_=dict(data=stmt.excluded.data)
)
conn.execute(stmt)
Try this code, this should work:
import platform
print(platform.python_version())
Here's the filter that I ended up using for strftime in Jinja2 and Flask
@app.template_filter('strftime')
def _jinja2_filter_datetime(date, fmt=None):
date = dateutil.parser.parse(date)
native = date.replace(tzinfo=None)
format='%b %d, %Y'
return native.strftime(format)
And then you use the filter like so:
{{car.date_of_manufacture|strftime}}
pod setup
works and should only take 10 mins on a solid connection. After that run: pod install --verbose
and you should see all the comments you would normally see when running a dependancy manager.
Hope that helps
You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams>
and you are passing var model = tm.Name.ToList();
name list. You have to pass list of Teams.
You have to pass following model
var model = new List<Teams>();
model.Add(new Teams { Name = new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name = new List<string>(){"John","XYZ"} });
return View(model);

I have been trying different values with JSON.parse(value)
and it seems to do the work:
// true
Boolean(JSON.parse("true"));
Boolean(JSON.parse("1"));

// false
Boolean(JSON.parse("0"));
Boolean(JSON.parse(0));
Boolean(JSON.parse("false"));
Boolean(JSON.parse(false));
Everybody seems to be suggesting that adding
using System.Configuration;
which is true.
But might I suggest that you think about installing ReSharper's Visual Studio extension?
With it installed, instead of seeing an error that a class isn't defined, you'll see a prompt that tells you which assembly it is in, asking you if you want it to add the needed using statement.
Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.
Spinlock and Mutex synchronization mechanisms are very common today to be seen.
Let's think about Spinlock first.
Basically it is a busy waiting action, which means that we have to wait for a specified lock is released before we can proceed with the next action. Conceptually very simple, while implementing it is not on the case. For example: If the lock has not been released then the thread was swap-out and get into the sleep state, should do we deal with it? How to deal with synchronization locks when two threads simultaneously request access ?
Generally, the most intuitive idea is dealing with synchronization via a variable to protect the critical section. The concept of Mutex is similar, but they are still different. Focus on: CPU utilization. Spinlock consumes CPU time to wait for do the action, and therefore, we can sum up the difference between the two:
In homogeneous multi-core environments, if the time spend on critical section is small than use Spinlock, because we can reduce the context switch time. (Single-core comparison is not important, because some systems implementation Spinlock in the middle of the switch)
In Windows, using Spinlock will upgrade the thread to DISPATCH_LEVEL, which in some cases may be not allowed, so this time we had to use a Mutex (APC_LEVEL).
From the Oracle documentation page about multiple inheritance type,we can find the accurate answer here. Here we should first know the type of multiple inheritance in java:-
Java "doesn't support the multiple inheritance of state, but it support multiple inheritance of implementation with default methods since java 8 release and multiple inheritance of type with interfaces.
Then here the question arises for "diamond problem" and how Java deal with that:-
In case of multiple inheritance of implementation java compiler gives compilation error and asks the user to fix it by specifying the interface name. Example here:-
interface A {
void method();
}
interface B extends A {
@Override
default void method() {
System.out.println("B");
}
}
interface C extends A {
@Override
default void method() {
System.out.println("C");
}
}
interface D extends B, C {
}
So here we will get error as:- interface D inherits unrelated defaults for method() from types B and C interface D extends B, C
You can fix it like:-
interface D extends B, C {
@Override
default void method() {
B.super.method();
}
}
In Conclusion we can say that java doesn't support multiple inheritance of state but it does support multiple inheritance of implementation and multiple inheritance of type.
Source files are often concatenated by tools (C, C++: header files, Javascript: bundlers). If you omit the newline character, you could introduce nasty bugs (where the last line of one source is concatenated with the first line of the next source file). Hopefully all the source code concat tools out there insert a newline between concatenated files anyway but that doesn't always seem to be the case.
The crux of the issue is - in most languages, newlines have semantic meaning and end-of-file is not a language defined alternative for the newline character. So you ought to terminate every statement/expression with a newline character -- including the last one.
I believe this is controlled by the css color
property applied to the element.
varchar, Don't store separating characters you may want to format the phone numbers differently for different uses. so store (619) 123-4567 as 6191234567 I work with phone directory data and have found this to be the best practice.
Missing ;
after var_dump($row)
instead of newdata you are using newdate in your predict code, verify once. and just use Coupon$estimate <- predict(model, Coupon)
It will work.
Given some C/C++ file foo.c
:
> clang -S -emit-llvm foo.c
Produces foo.ll
which is an LLVM IR file.
The -emit-llvm
option can also be passed to the compiler front-end directly, and not the driver by means of -cc1
:
> clang -cc1 foo.c -emit-llvm
Produces foo.ll
with the IR. -cc1
adds some cool options like -ast-print
. Check out -cc1 --help
for more details.
To compile LLVM IR further to assembly, use the llc
tool:
> llc foo.ll
Produces foo.s
with assembly (defaulting to the machine architecture you run it on). llc
is one of the LLVM tools - here is its documentation.

A possibility is to declare the variable at the index.html because it is really global. It can be done adding a javascript method to return the value of the variable, and it will be READ ONLY.
An example of this solution can be found at this answer: https://stackoverflow.com/a/62485644/1178478
This works for me, try:
ECHO %DATE:~7,2%_%DATE:~4,2%_%DATE:~12,2%
Use a for
loop instead of .forEach()
var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false
for(var call of myObj) {
console.log(call)
var a = call['a'], b = call['b']
if(a == null || b == null) {
result = false
break
}
}
Go on the missing declaration with cursor and press alt+enter
On input:
step="any"

On script:
$(".two-decimals").change(function(){
this.value = parseFloat(this.value).toFixed(2);
});
This is a good question. You often see people use re.compile without reason. It lessens readability. But sure there are lots of times when pre-compiling the expression is called for. Like when you use it repeated times in a loop or some such.
It's like everything about programming (everything in life actually). Apply common sense.
You can declare local variables in MySQL triggers, with the DECLARE
syntax.
Here's an example:
DROP TABLE IF EXISTS foo;
CREATE TABLE FOO (
i SERIAL PRIMARY KEY
);
DELIMITER //
DROP TRIGGER IF EXISTS bar //
CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
DECLARE x INT;
SET x = NEW.i;
SET @a = x; -- set user variable outside trigger
END//
DELIMITER ;
SET @a = 0;
SELECT @a; -- returns 0
INSERT INTO foo () VALUES ();
SELECT @a; -- returns 1, the value it got during the trigger
When you assign a value to a variable, you must ensure that the query returns only a single value, not a set of rows or a set of columns. For instance, if your query returns a single value in practice, it's okay but as soon as it returns more than one row, you get "ERROR 1242: Subquery returns more than 1 row
".
You can use LIMIT
or MAX()
to make sure that the local variable is set to a single value.
CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
DECLARE x INT;
SET x = (SELECT age FROM users WHERE name = 'Bill');
-- ERROR 1242 if more than one row with 'Bill'
END//
CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
DECLARE x INT;
SET x = (SELECT MAX(age) FROM users WHERE name = 'Bill');
-- OK even when more than one row with 'Bill'
END//
Not the best way but it works

You could use "child process" module of nodejs to execute any shell commands or scripts with in nodejs. Let me show you with an example, I am running a shell script(hi.sh) with in nodejs.
hi.sh
echo "Hi There!"
node_program.js
const { exec } = require('child_process');
var yourscript = exec('sh hi.sh',
(error, stdout, stderr) => {
console.log(stdout);
console.log(stderr);
if (error !== null) {
console.log(`exec error: ${error}`);
}
});
Here, when I run the nodejs file, it will execute the shell file and the output would be:
Run
node node_program.js
output
Hi There!
You can execute any script just by mentioning the shell command or shell script in exec
callback.
Hope this helps! Happy coding :)

You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)
(function( func ) {
$.fn.addClass = function() { // replace the existing function on $.fn
func.apply( this, arguments ); // invoke the original function
this.trigger('classChanged'); // trigger the custom event
return this; // retain jQuery chainability
}
})($.fn.addClass); // pass the original function as an argument
(function( func ) {
$.fn.removeClass = function() {
func.apply( this, arguments );
this.trigger('classChanged');
return this;
}
})($.fn.removeClass);
Then the rest of your code would be as simple as you'd expect.
$(selector).on('classChanged', function(){ /*...*/ });
Update:
This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObserver
s as explained in the accepted answer here would be necessary.
Also as a couple improvements to these methods:
classAdded
) or removed (classRemoved
) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)Only trigger classChanged
if any classes are actually changed
(function( func ) {
$.fn.addClass = function(n) { // replace the existing function on $.fn
this.each(function(i) { // for each element in the collection
var $this = $(this); // 'this' is DOM element in this context
var prevClasses = this.getAttribute('class'); // note its original classes
var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
$.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
if( !$this.hasClass(className) ) { // only when the class is not already present
func.call( $this, className ); // invoke the original function to add the class
$this.trigger('classAdded', className); // trigger a classAdded event
}
});
prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
});
return this; // retain jQuery chainability
}
})($.fn.addClass); // pass the original function as an argument
(function( func ) {
$.fn.removeClass = function(n) {
this.each(function(i) {
var $this = $(this);
var prevClasses = this.getAttribute('class');
var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
$.each(classNames.split(/\s+/), function(index, className) {
if( $this.hasClass(className) ) {
func.call( $this, className );
$this.trigger('classRemoved', className);
}
});
prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
});
return this;
}
})($.fn.removeClass);
With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:
$(document).on('classAdded', '#myElement', function(event, className) {
if(className == "something") { /* do something */ }
});
