I think the cleanest way to do this is with Mockito.spy(). It's a bit more lightweight than creating a separate class to mock and pass around.
Move your environment variable fetching to another method:
@VisibleForTesting
String getEnvironmentVariable(String envVar) {
return System.getenv(envVar);
}
Now in your unit test do this:
@Test
public void test() {
ClassToTest classToTest = new ClassToTest();
ClassToTest classToTestSpy = Mockito.spy(classToTest);
Mockito.when(classToTestSpy.getEnvironmentVariable("key")).thenReturn("value");
// Now test the method that uses getEnvironmentVariable
assertEquals("changedvalue", classToTestSpy.methodToTest());
}

var myobject = new MyClass1("5678999", "text");
var dto = { MyClass1: myobject };
console.log(JSON.stringify(dto));
EDIT:
JSON.stringify
will stringify all 'properties' of your class. If you want to persist only some of them, you can specify them individually like this:
var dto = { MyClass1: {
property1: myobject.property1,
property2: myobject.property2
}};
This is not possible with the magic find methods. Try using the query builder:
$result = $em->getRepository("Orders")->createQueryBuilder('o')
->where('o.OrderEmail = :email')
->andWhere('o.Product LIKE :product')
->setParameter('email', '[email protected]')
->setParameter('product', 'My Products%')
->getQuery()
->getResult();
As you can see in the generated SQL statements the difference is not the "OR" as some may suspect. It is how the WHERE and JOIN is placed.
(example from https://docs.djangoproject.com/en/dev/topics/db/queries/#spanning-multi-valued-relationships)
Blog.objects.filter(entry__headline__contains='Lennon', entry__pub_date__year=2008)
This will give you all the Blogs that have one entry with both (entry_headline_contains='Lennon') AND (entry__pub_date__year=2008), which is what you would expect from this query. Result: Book with {entry.headline: 'Life of Lennon', entry.pub_date: '2008'}
Blog.objects.filter(entry__headline__contains='Lennon').filter(entry__pub_date__year=2008)
This will cover all the results from Example 1, but it will generate slightly more result. Because it first filters all the blogs with (entry_headline_contains='Lennon') and then from the result filters (entry__pub_date__year=2008).
The difference is that it will also give you results like: Book with {entry.headline: 'Lennon', entry.pub_date: 2000}, {entry.headline: 'Bill', entry.pub_date: 2008}
I think it is this one you need:
Book.objects.filter(inventory__user__profile__vacation=False, inventory__user__profile__country='BR')
And if you want to use OR please read: https://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects
First, define a new function to read the input (according to the structure of your input) and store the string, which means the memory in stack used. Set the length of string to be enough for your input.
Second, use strlen
to measure the exact used length of string stored before, and malloc
to allocate memory in heap, whose length is defined by strlen
. The code is shown below.
int strLength = strlen(strInStack);
if (strLength == 0) {
printf("\"strInStack\" is empty.\n");
}
else {
char *strInHeap = (char *)malloc((strLength+1) * sizeof(char));
strcpy(strInHeap, strInStack);
}
return strInHeap;
Finally, copy the value of strInStack
to strInHeap
using strcpy
, and return the pointer to strInHeap
. The strInStack
will be freed automatically because it only exits in this sub-function.
You can try below code. it’s very easy method for push new fragment from old fragment.
private int mContainerId;
private FragmentTransaction fragmentTransaction;
private FragmentManager fragmentManager;
private final static String TAG = "DashBoardActivity";
public void replaceFragment(Fragment fragment, String TAG) {
try {
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(mContainerId, fragment, tag);
fragmentTransaction.addToBackStack(tag);
fragmentTransaction.commitAllowingStateLoss();
} catch (Exception e) {
// TODO: handle exception
}
}
I've had a similar issue with one of my phones. I was unable to connect and use usb debugging on any of my computers. In the end, I had to restart the usb debugging on the phone manually [doing so using the Developer menu was not enough].
There's only one command you have to run on your phone [I did it using Terminal Emulator
app]:
adb usb
And that was it.
Hope this helps someone in the future.
Its very simple, just add the quartzCore header in your file(for that you have to add the quartz framework to your project)
and then do this
[[button layer] setCornerRadius:8.0f];
[[button layer] setMasksToBounds:YES];
[[button layer] setBorderWidth:1.0f];
you can change the float values as required.
enjoy.
Here's some typical modern code ...
self.buttonTag.layer.borderWidth = 1.0f;
self.buttonCancel.layer.borderWidth = 1.0f;
self.buttonTag.layer.borderColor = [UIColor blueColor].CGColor;
self.buttonCancel.layer.borderColor = [UIColor blueColor].CGColor;
self.buttonTag.layer.cornerRadius = 4.0f;
self.buttonCancel.layer.cornerRadius = 4.0f;
that's a similar look to segmented controls.
UPDATE for Swift:
Just do:
button.layer.cornerRadius = 8.0
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.black.cgColor

Use .unshift()
to add to the beginning of an array.
TheArray.unshift(TheNewObject);
See MDN for doc on unshift()
and here for doc on other array methods.
FYI, just like there's .push()
and .pop()
for the end of the array, there's .shift()
and .unshift()
for the beginning of the array.
For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.
1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication
I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.
You can also visit the "Preferences" tab from the H2 Console and shutdown all active sessions by pressing the shutdown button.
This solution is deprecated
failure|fail|error() is deprecated and will be removed in 2.1, please use promise-style instead.
so you have to use
Project.update(
// Set Attribute values
{
title: 'a very different title now'
},
// Where clause / criteria
{
_id: 1
}
).then(function() {
console.log("Project with id =1 updated successfully!");
}).catch(function(e) {
console.log("Project update failed !");
})
And you can use
.complete()
as well

When adding support for mimetype (as suggested by @ProVega) then it is also best practice to remove the type before adding it - this is to prevent unexpected errors when deploying to servers where support for the type already exists, for example:
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
You'd need to make the enum expose value
somehow, e.g.
public enum Tax {
NONE(0), SALES(10), IMPORT(5);
private final int value;
private Tax(int value) {
this.value = value;
}
public int getValue() {
return value;
}
}
...
public int getTaxValue() {
Tax tax = Tax.NONE; // Or whatever
return tax.getValue();
}
(I've changed the names to be a bit more conventional and readable, btw.)
This is assuming you want the value assigned in the constructor. If that's not what you want, you'll need to give us more information.
public static void Serialize(object value, Stream s)
{
using (StreamWriter writer = new StreamWriter(s))
using (JsonTextWriter jsonWriter = new JsonTextWriter(writer))
{
JsonSerializer ser = new JsonSerializer();
ser.Serialize(jsonWriter, value);
jsonWriter.Flush();
}
}
public static T Deserialize<T>(Stream s)
{
using (StreamReader reader = new StreamReader(s))
using (JsonTextReader jsonReader = new JsonTextReader(reader))
{
JsonSerializer ser = new JsonSerializer();
return ser.Deserialize<T>(jsonReader);
}
}
Initially I tried various programmatic approach in my html, JS to clear browser cache. Nothing works on latest Chrome.
Finally, I ended up with .htaccess:
<IfModule mod_headers.c>
Header set Cache-Control "no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires 0
</IfModule>
Tested in Chrome, Firefox, Opera

It is indeed possible to change a div
elements' width in jQuery:
$("#div").css("width", "300px");
However, what you're describing can be better and more effectively achieved in CSS by setting a width as a percentage:
#div {
width: 75%;
/* You can also specify min/max widths */
min-width: 300px;
max-width: 960px;
}
This div will then always be 75% the width of the screen, unless the screen width means the div will be smaller than 300px, or bigger than 960px.

return yearDiff;

Using this code you can write to a text file in the SDCard. Along with it, you need to set a permission in the Android Manifest.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
This is the code :
public void generateNoteOnSD(Context context, String sFileName, String sBody) {
try {
File root = new File(Environment.getExternalStorageDirectory(), "Notes");
if (!root.exists()) {
root.mkdirs();
}
File gpxfile = new File(root, sFileName);
FileWriter writer = new FileWriter(gpxfile);
writer.append(sBody);
writer.flush();
writer.close();
Toast.makeText(context, "Saved", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
Before writing files you must also check whether your SDCard is mounted & the external storage state is writable.
Environment.getExternalStorageState()

In your HTML page add an element that CKEditor should replace:
<textarea name="content" id="editor"></textarea>
Load the classic editor build (here CDN location is used):
<script src="https://cdn.ckeditor.com/ckeditor5/10.0.1/classic/ckeditor.js"></script>
Call the ClassicEditor.create() method.
<script>
ClassicEditor
.create( document.querySelector( '#editor' ) )
.catch( error => {
console.error( error );
} );
</script>
Example
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CKEditor 5 - Classic editor</title>
<script src="https://cdn.ckeditor.com/ckeditor5/10.0.1/classic/ckeditor.js"></script>
</head>
<body>
<h1>Classic editor</h1>
<textarea name="content" id="editor">
<p>This is some sample content.</p>
</textarea>
<script>
ClassicEditor
.create( document.querySelector( '#editor' ) )
.catch( error => {
console.error( error );
} );
</script>
</body>
</html>
This example is for the specific classic editor. FOr other variants, only CDN will change.
Yes, you could make an indexer on your Record class that maps from the property name to the correct property. This would keep all the binding from property name to property in one place eg:
public class Record
{
public string ItemType { get; set; }
public string this[string propertyName]
{
set
{
switch (propertyName)
{
case "itemType":
ItemType = value;
break;
// etc
}
}
}
}
Alternatively, as others have mentioned, use reflection.
If you do not need all the functionality PostGIS offers, Postgres (nowadays) offers an extension module called earthdistance. It uses the point or cube data type depending on your accuracy needs for distance calculations.
You can now use the earth_box function to -for example- query for points within a certain distance of a location.
There are a to of situations where the above CSS solutions do not work. For instance a transparent fixed header and a sticky footer on the same page. To prevent the top bounce in safari messing things and causing flashes on full screen sliders, you can use this.
if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1) {
$window.bind('mousewheel', function(e) {
if (e.originalEvent.wheelDelta / 120 > 0) {
if ($window.scrollTop() < 2) return false;
}
});
}
For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:
long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));
This will print:
Duration: 1:23:45.678
This simulates a character array but you can substitute SUBSTR for ELT to simulate a string array
declare t_tipos varchar(255) default 'ABCDE';
declare t_actual char(1);
declare t_indice integer default 1;
while t_indice<length(t_tipos)+1 do
set t_actual=SUBSTR(t_tipos,t_indice,1);
select t_actual;
set t_indice=t_indice+1;
end while;
Duplicated id
for pairs name
and city
:
select s.id, t.*
from [stuff] s
join (
select name, city, count(*) as qty
from [stuff]
group by name, city
having count(*) > 1
) t on s.name = t.name and s.city = t.city
I like using Tiny Types which would wrap either a double, BigDecimal, or int as previous answers have suggested. (I would use a double unless precision problems crop up).
A Tiny Type gives you type safety so you don't confused a double money with other doubles.
check the code below this will be helpful for you:
<script type="text/javascript">
window.opener.location.href = '@Url.Action("Action", "EventstController")', window.close();
</script>
You can just call "exit 1", and the build will fail at that point and not continue. I wound up making a passthrough make function to handle it for me, and call safemake instead of make for building:
function safemake {
make "$@"
if [ "$?" -ne 0 ]; then
echo "ERROR: BUILD FAILED"
exit 1
else
echo "BUILD SUCCEEDED"
fi
}
I don't know if this helps:
suppose you want to run a sql script (test.sql) from the command line:
mysql < test.sql
and the contents of test.sql is something like:
SELECT * FROM information_schema.SCHEMATA;
\! echo "I like to party...";
The console will show something like:
CATALOG_NAME SCHEMA_NAME DEFAULT_CHARACTER_SET_NAME
def information_schema utf8
def mysql utf8
def performance_schema utf8
def sys utf8
I like to party...
So you can execute terminal commands inside an sql statement by just using \!
, provided the script is run via a command line.
\! #terminal_commands

You use:
yourcommand > /dev/null 2>&1
If it should run in the Background add an &
yourcommand > /dev/null 2>&1 &
>/dev/null 2>&1
means redirect stdout
to /dev/null
AND stderr
to the place where stdout
points at that time
If you want stderr
to occur on console and only stdout
going to /dev/null
you can use:
yourcommand 2>&1 > /dev/null
In this case stderr
is redirected to stdout
(e.g. your console) and afterwards the original stdout
is redirected to /dev/null
If the program should not terminate you can use:
nohup yourcommand &
Without any parameter all output lands in nohup.out
I had the same problem but mine worked fine. Turn off your firewall, antivirus. Make sure your port 80 is enabled and both pcs are set to be remotely accessed. In each pc under users, add new user using the host ip address of the other pc. Restart all services. Put your wampserver online. It should connect
db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})
You can also use NumberLong.

If you work with an IDE like NetBeans, you can specify the Xlint:unchecked
compiler option in the propertys of your project.
Just go to projects window, right click in the project and then click in Properties
.
In the window that appears search the Compiling
category, and in the textbox labeled Additional Compiler Options
set the Xlint:unchecked
option.
Thus, the setting will remain set for every time you compile the project.
I had the same error as described by title, but for me it was simply installing Microsoft access 12.0 oledb redistributable to use with LinqToExcel.
A simple date comparison in pure JS should be sufficient:
// Create date from input value
var inputDate = new Date("11/21/2011");
// Get today's date
var todaysDate = new Date();
// call setHours to take the time out of the comparison
if(inputDate.setHours(0,0,0,0) == todaysDate.setHours(0,0,0,0)) {
// Date equals today's date
}
Here's a working JSFiddle.
To do as the answer above, you can override the onAttach
method of fragment:
public static class DummySectionFragment extends Fragment{
...
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
DBHelper = new DatabaseHelper(activity);
}
}
Assuming you are talking about the ActionEvent
class, then there is a big difference between the two methods.
getActionCommand()
gives you a String representing the action command. The value is component specific; for a JButton
you have the option to set the value with setActionCommand(String command)
but for a JTextField
if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField
.
getSource()
is specified by the EventObject
class that ActionEvent
is a child of (via java.awt.AWTEvent
). This gives you a reference to the object that the event came from.
Edit:
Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.
public class Events implements ActionListener {
private static JFrame frame;
public static void main(String[] args) {
frame = new JFrame("JTextField events");
frame.getContentPane().setLayout(new FlowLayout());
JTextField field1 = new JTextField(10);
field1.addActionListener(new Events());
frame.getContentPane().add(new JLabel("Field with no action command set"));
frame.getContentPane().add(field1);
JTextField field2 = new JTextField(10);
field2.addActionListener(new Events());
field2.setActionCommand("my action command");
frame.getContentPane().add(new JLabel("Field with an action command set"));
frame.getContentPane().add(field2);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(220, 150);
frame.setResizable(false);
frame.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent evt) {
String cmd = evt.getActionCommand();
JOptionPane.showMessageDialog(frame, "Command: " + cmd);
}
}
In Python 3, you can use
"one" in d.values()
to test if "one"
is among the values of your dictionary.
In Python 2, it's more efficient to use
"one" in d.itervalues()
instead.
Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.
The R-inferno, or the basic R-documentation will explain why using df$* is not the best approach here. From the help page for "[" :
"Indexing by [ is similar to atomic vectors and selects a list of the specified element(s). Both [[ and $ select a single element of the list. The main difference is that $ does not allow computed indices, whereas [[ does. x$name is equivalent to x[["name", exact = FALSE]]. Also, the partial matching behavior of [[ can be controlled using the exact argument. "
I recommend using the [row,col]
notation instead. Example:
Rgames: foo
x y z
[1,] 1e+00 1 0
[2,] 2e+00 2 0
[3,] 3e+00 1 0
[4,] 4e+00 2 0
[5,] 5e+00 1 0
[6,] 6e+00 2 0
[7,] 7e+00 1 0
[8,] 8e+00 2 0
[9,] 9e+00 1 0
[10,] 1e+01 2 0
Rgames: foo<-as.data.frame(foo)
Rgames: foo[foo$y==2,3]<-foo[foo$y==2,1]
Rgames: foo
x y z
1 1e+00 1 0e+00
2 2e+00 2 2e+00
3 3e+00 1 0e+00
4 4e+00 2 4e+00
5 5e+00 1 0e+00
6 6e+00 2 6e+00
7 7e+00 1 0e+00
8 8e+00 2 8e+00

10 1e+01 2 1e+01
They all do different things, since matplotlib uses a hierarchical order in which a figure window contains a figure which may consist of many axes. Additionally, there are functions from the pyplot interface and there are methods on the Figure
class. I will discuss both cases below.
pyplot
is a module that collects a couple of functions that allow matplotlib to be used in a functional manner. I here assume that pyplot
has been imported as import matplotlib.pyplot as plt
.
In this case, there are three different commands that remove stuff:
plt.cla()
clears an axes, i.e. the currently active axes in the current figure. It leaves the other axes untouched.
plt.clf()
clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.
plt.close()
closes a window, which will be the current window, if not specified otherwise.
Which functions suits you best depends thus on your use-case.
The close()
function furthermore allows one to specify which window should be closed. The argument can either be a number or name given to a window when it was created using figure(number_or_name)
or it can be a figure instance fig
obtained, i.e., usingfig = figure()
. If no argument is given to close()
, the currently active window will be closed. Furthermore, there is the syntax close('all')
, which closes all figures.
Additionally, the Figure
class provides methods for clearing figures.
I'll assume in the following that fig
is an instance of a Figure
:
fig.clf()
clears the entire figure. This call is equivalent to plt.clf()
only if fig
is the current figure.
fig.clear()
is a synonym for fig.clf()
Note that even del fig
will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig)
as described above.
I could do this (demo):

JQuery Mobile has multipage feature. But I am not sure about Desktop Web Applications.
What had caused this error on my side was the following line
include_once dirname(__FILE__) . './Config.php';
I managed to realize it was the culprit when i added the lines:
//error_reporting(E_ALL | E_DEPRECATED | E_STRICT);
//ini_set('display_errors', 1);
to all my php files.
To solve the path issue
i canged the offending line to:
include_once dirname(__FILE__) . '/Config.php';
No, not from code behind. A postback is a request initiated from a page on the client back to itself on the server using the Http POST method. On the server side you can request a redirect but the will be Http GET request.
Do it without service
If you are so serious about doing it with services using mediaplayer
Intent svc=new Intent(this, BackgroundSoundService.class);
startService(svc);
public class BackgroundSoundService extends Service {
private static final String TAG = null;
MediaPlayer player;
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
player = MediaPlayer.create(this, R.raw.idil);
player.setLooping(true); // Set looping
player.setVolume(100,100);
}
public int onStartCommand(Intent intent, int flags, int startId) {
player.start();
return 1;
}
public void onStart(Intent intent, int startId) {
// TO DO
}
public IBinder onUnBind(Intent arg0) {
// TO DO Auto-generated method
return null;
}
public void onStop() {
}
public void onPause() {
}
@Override
public void onDestroy() {
player.stop();
player.release();
}
@Override
public void onLowMemory() {

PostgreSql is very advanced when related to logging techniques
Logs are stored in Installationfolder/data/pg_log folder
. While log settings are placed in postgresql.conf
file.
Log format is usually set as stderr
. But CSV log format is recommended. In order to enable CSV format change in
log_destination = 'stderr,csvlog'
logging_collector = on
In order to log all queries, very usefull for new installations, set min. execution time for a query
log_min_duration_statement = 0
In order to view active Queries on your database, use
SELECT * FROM pg_stat_activity
To log specific queries set query type
log_statement = 'all' # none, ddl, mod, all
For more information on Logging queries see PostgreSql Log.
The following is an instantiation of the various "just print it" suggestions. I found it instructive.
#include "stdio.h"
int main() {
static int x = 5;
static int *p = &x;
printf("(int) p => %d\n",(int) p);
printf("(int) p++ => %d\n",(int) p++);
x = 5; p = &x;
printf("(int) ++p => %d\n",(int) ++p);
x = 5; p = &x;
printf("++*p => %d\n",++*p);
x = 5; p = &x;
printf("++(*p) => %d\n",++(*p));
x = 5; p = &x;
printf("++*(p) => %d\n",++*(p));
x = 5; p = &x;
printf("*p++ => %d\n",*p++);
x = 5; p = &x;
printf("(*p)++ => %d\n",(*p)++);
x = 5; p = &x;
printf("*(p)++ => %d\n",*(p)++);
x = 5; p = &x;
printf("*++p => %d\n",*++p);
x = 5; p = &x;
printf("*(++p) => %d\n",*(++p));
return 0;
}
It returns
(int) p => 256688152
(int) p++ => 256688152
(int) ++p => 256688156
++*p => 6
++(*p) => 6
++*(p) => 6
*p++ => 5
(*p)++ => 5
*(p)++ => 5
*++p => 0
*(++p) => 0
I cast the pointer addresses to int
s so they could be easily compared.
I compiled it with GCC.
I wanted to add this answer because I spent a great deal of time looking for a fast, reliable method to do this and no complete examples of using OpenXMLWriter for this purpose existed anywhere that I could find.
First, COM/Interop (which many of the other answers use) is OK for this purpose, but it suffers from some sensitivities. I've used it for decades and it's mostly stable, but when implementing a data warehouse front-end for hundreds of users, I found it to be subject to too many issues depending on the machine and what the user did, so I switched to OpenXML. OpenXML DOM is fairly good for this purpose, but it's slower than using OpenXMLWriter. When you get into large datasets (100K+) with lots of columns, DOM is much slower than OpenXMLWriter, so I use the latter. The method below writes 420K+ rows with 30+ fields in less than 30 seconds.
I hope the comments are sufficient to guide anyone through what it's doing. It is simplified, in that it writes all values to the file as strings, but you can implement logic to write various datatypes (and use various cell formats) based on the content of your data. You can also adapt this for use on a DataGridView (instead of a DataTable) by changing just a few things (namely the loops through columns/rows).
A reference to DocumentFormat.OpenXML (d/l with the OpenXML SDK) and WindowsBase is required.

If you know the UTC offset then you can pass it and get the time using the following function:
function calcTime(city, offset) {
// create Date object for current location
var d = new Date();
// convert to msec
// subtract local time zone offset
// get UTC time in msec
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
// create new Date object for different city
// using supplied offset
var nd = new Date(utc + (3600000*offset));
// return time as a string
return "The local time for city"+ city +" is "+ nd.toLocaleString();
}
alert(calcTime('Bombay', '+5.5'));

The variable $_POST
is automatically populated.
Try var_dump($_POST);
to see the contents.
You can access individual values like this: echo $_POST["name"];
This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”
If your post data is in another format (e.g. JSON or XML, you can do something like this:
$post = file_get_contents('php://input');
and $post
will contain the raw data.
Assuming you're using the standard $_POST
variable, you can test if a checkbox is checked like this:
if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
...
}
If you have an array of checkboxes (e.g.
<form action="myscript.php" method="post">
<input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
<input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
<input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
<input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
<input type="checkbox" name="myCheckbox[]" value="E" />val5
<input type="submit" name="Submit" value="Submit" />
</form>
Using [ ]
in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox']
won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.
For instance, if I checked all the boxes, $_POST['myCheckbox']
would be an array consisting of: {A, B, C, D, E}
. Here's an example of how to retrieve the array of values and display them:
$myboxes = $_POST['myCheckbox'];
if(empty($myboxes))
{
echo("You didn't select any boxes.");
}
else
{
$i = count($myboxes);
echo("You selected $i box(es): <br>");
for($j = 0; $j < $i; $j++)
{
echo $myboxes[$j] . "<br>";
}
}
You can also use replaceAll(search, replaceWith)
[MDN].
Then, make sure you have a string by wrapping one type of quotes by a different type:
'a "b" c'.replaceAll('"', "'")
// result: "a 'b' c"
'a "b" c'.replaceAll(`"`, `'`)
// result: "a 'b' c"
// Using RegEx. You MUST use a global RegEx(Meaning it'll match all occurrences).
'a "b" c'.replaceAll(/\"/g, "'")
// result: "a 'b' c"
Important(!) if you choose regex:
when using a
regexp
you have to set the global ("g") flag; otherwise, it will throw a TypeError: "replaceAll must be called with a global RegExp".
You should have to use DateTime.TryParseExact
.
var newDate = DateTime.ParseExact("20111120",
"yyyyMMdd",
CultureInfo.InvariantCulture);
OR
string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;
if (DateTime.TryParseExact(str,
format,
System.Globalization.CultureInfo.InvariantCulture,
System.Globalization.DateTimeStyles.None,
out date))
{
//valid
}
strSearch in this case is probably null (not simply empty).
Try using
String.IsNullOrEmpty(strSearch)
if you are just trying to determine if the string doesn't have any contents.
For single check try
myCheckBox.checked=1
_x000D_
<input type="checkbox" id="myCheckBox"> Call to her
_x000D_
for multi try
document.querySelectorAll('.imChecked').forEach(c=> c.checked=1)
_x000D_
Buy wine: <input type="checkbox" class="imChecked"><br>_x000D_
Play smooth-jazz music: <input type="checkbox"><br>_x000D_
Shave: <input type="checkbox" class="imChecked"><br>

egrep -v "^[[:blank:]]*#"

egrep -v "^[[:blank:]]*(#|$)"
should filter out both comments and empty lines, as is frequently useful.

For student level programs, Clang has the benefit that it is, by default, stricter wrt. the C standard. For example, the following K&R version of Hello World is accepted without warning by GCC, but rejected by Clang with some pretty descriptive error messages:
main()
{
puts("Hello, world!");
}
With GCC, you have to give it -Werror
to get it to really make a point about this not being a valid C89 program. Also, you still need to use c99
or gcc -std=c99
to get the C99 language.
Going with what you've started:
row = [[]]
crimefile = open(fileName, 'r')
for line in crimefile.readlines():
tmp = []
for element in line[0:-1].split(','):
tmp.append(element)
row.append(tmp)
Be ware with this:
RegisterGlobalFilters(GlobalFilterCollection filters) {
filters.Add(new System.Web.Mvc.AuthorizeAttribute());
}
By default, SBT runs the application on port 9000:
sbt run
To specify a port add -Dhttp.port flag, for example:
sbt run -Dhttp.port=8080
Using the -Dhttp.port flag, you can debug multiple applications on your development machine. Please note, you can also use the -Dhttp.port flag in test and production environments.
There could many causes to this problems
What I have experienced are:
1) 127.0.0.1 localhost
entry was duplicated in hosts file
2) Apache mod_rewrite
was not enabled
Regardless of the cause, backing up your www
folder, vhost configuration file (and httpd configuration file) will help.
And such process takes a few minutes.

Pattern.matches(emailRegex,"You_Input_Mail_Id");
This is the regex to match valid email addresses.

You might want to look at ConcurrentDoublyLinkedList written by Doug Lea based on Paul Martin's "A Practical Lock-Free Doubly-Linked List". It does not implement the java.util.List interface, but offers most methods you would use in a List.
According to the javadoc:
A concurrent linked-list implementation of a Deque (double-ended queue). Concurrent insertion, removal, and access operations execute safely across multiple threads. Iterators are weakly consistent, returning elements reflecting the state of the deque at some point at or since the creation of the iterator. They do not throw ConcurrentModificationException, and may proceed concurrently with other operations.
Do you really need to do that programmatically?
Just considering the title: You could use a ShapeDrawable as android:background…
For example, let's define res/drawable/my_custom_background.xml
as:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="2dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp" />
<stroke
android:width="1dp"
android:color="@android:color/white" />
</shape>
and define android:background="@drawable/my_custom_background".
I've not tested but it should work.
Update:
I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/border"
android:padding="10dip" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
[... more TextView ...]
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello World, SOnich"
/>
</LinearLayout>
and a res/drawable/border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="5dip"
android:color="@android:color/white" />
</shape>
Reported to work on a gingerbread device. Note that you'll need to relate android:padding
of the LinearLayout to the android:width
shape/stroke's value. Please, do not use @android:color/white
in your final application but rather a project defined color.
You could apply android:background="@drawable/border" android:padding="10dip"
to each of the LinearLayout from your provided sample.
As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…
Your problem resides clearly in the use of getBorder.set{Width,Height}(100);
. Why do you do that in an onClick method?
I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.
To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…
There's no need to manually set the colors. Instead, specify a grayscale colormap...
import numpy as np
import matplotlib.pyplot as plt
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()
plt.show()
Or, if you'd prefer a wider range of colormaps, you can also specify the cmap
kwarg to scatter
. To use the reversed version of any of these, just specify the "_r
" version of any of them. E.g. gray_r
instead of gray
. There are several different grayscale colormaps pre-made (e.g. gray
, gist_yarg
, binary
, etc).
import matplotlib.pyplot as plt
import numpy as np
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()

I often use a quick-n-dirty trick to read a fixed number of arguments from the command-line:
[filename] = sys.argv[1:]
in_file = open(filename) # Don't need the "r"
This will assign the one argument to filename
and raise an exception if there isn't exactly one argument.
because your jQuery code is wrong. Correctly would be:
var theParent = $(this).parent().get(0);
$(theParent).css('z-index', 3000);
Why not get the html first then pass it to the web view?
private String getHtml(String url){
HttpGet pageGet = new HttpGet(url);
ResponseHandler<String> handler = new ResponseHandler<String>() {
public String handleResponse(HttpResponse response) throws ClientProtocolException, IOException {
HttpEntity entity = response.getEntity();
String html;
if (entity != null) {
html = EntityUtils.toString(entity);
return html;
} else {
return null;
}
}
};
pageHTML = null;
try {
while (pageHTML==null){
pageHTML = client.execute(pageGet, handler);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return pageHTML;
}
@Override
public void customizeWebView(final ServiceCommunicableActivity activity, final WebView webview, final SearchResult mRom) {
mRom.setFileSize(getFileSize(mRom.getURLSuffix()));
webview.getSettings().setJavaScriptEnabled(true);
WebViewClient anchorWebViewClient = new WebViewClient()
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
//Do what you want to with the html
String html = getHTML(url);
if( html!=null && !url.equals(lastLoadedURL)){
lastLoadedURL = url;
webview.loadDataWithBaseURL(url, html, null, "utf-8", url);
}
}
This should roughly do what you want to do. It is adapted from Is it possible to get the HTML code from WebView and shout out to https://stackoverflow.com/users/325081/aymon-fournier for his answer.
To remove untracked files / directories do:
git clean -fdx
-f - force
-d - directories too
-x - remove ignored files too ( don't use this if you don't want to remove ignored files)
Use with Caution!
These commands can permanently delete arbitrary files, that you havn't thought of at first. Please double check and read all the comments below this answer and the --help section, etc., so to know all details to fine-tune your commands and surely get the expected result.
try any of the following,
background-size: contain;
background-size: cover;
background-size: 100%;
.container{
background-size: 100%;
}
The "JavaScript" way:
var lang = navigator.language || navigator.userLanguage; //no ?s necessary
Really you should be doing language detection on the server, but if it's absolutely necessary to know/use via JavaScript, it can be gotten.
The next()
moves the cursor froward one row from its current position in the resultset
. so its evident that if(rs.next())
means that if the next row is not null
(means if it exist), Go Ahead.
Now w.r.t your problem,
ResultSet rs = stmt.executeQuery(sql); //This is wrong
^
note that executeQuery(String) is used in case you use a sql-query as string.
Whereas when you use a PreparedStatement, use executeQuery() which executes the SQL query in this PreparedStatement
object and returns the ResultSet
object generated by the query.
Solution :
Use : ResultSet rs = stmt.executeQuery();
It allows servlets to have multiple servlet mappings:
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/bill</url-pattern>
</servlet-mapping>
It allows filters to be mapped on the particular servlet:
<filter-mapping>
<filter-name>Filter1</filter-name>
<servlet-name>Servlet1</servlet-name>
</filter-mapping>
Your proposal would support neither of them. Note that the web.xml
is read and parsed only once during application's startup, not on every HTTP request as you seem to think.
Since Servlet 3.0, there's the @WebServlet
annotation which minimizes this boilerplate:
@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {
Go to the Preferences menu command under menu Settings, and select Language Menu/Tab Settings, depending on your version. Earlier versions use Tab Settings. Later versions use Language. Click the Replace with space check box. Set the size to 4.

From page 106 of the ggplot2 book by Hadley Wickham:
The default colour scheme, scale_colour_hue picks evenly spaced hues around the hcl colour wheel.
With a bit of reverse engineering you can construct this function:
ggplotColours <- function(n = 6, h = c(0, 360) + 15){
if ((diff(h) %% 360) < 1) h[2] <- h[2] - 360/n
hcl(h = (seq(h[1], h[2], length = n)), c = 100, l = 65)
}
Demonstrating this in barplot:
y <- 1:3
barplot(y, col = ggplotColours(n = 3))
In Groovy:
There is no need to create a File
instance to parse the string in groovy. It can be done as follows:
String path = "C:/aaa/bbb/ccc/ddd/test.java"
path.split('/')[-2] // this will return ddd
The split will create the array [C:, aaa, bbb, ccc, ddd, test.java]
and index -2
will point to entry before the last one, which in this case is ddd
While this doesn't directly answer the question, there is great book available for free which will help you learn the basics called ProGit. If you would prefer the dead-wood version to a collection of bits you can purchase it from Amazon.
You can use one of the following:
DateTime.current.midnight
DateTime.current.beginning_of_day
DateTime.current.to_date
Your setters are strange, which is why you may be seeing a problem.
First, consider whether you even need these setters - if so, they should take a List<string>
, not just a string
:
set
{
_subHead = value;
}
These lines:
newSec.subHead.Add("test string");
Are calling the getter and then call Add
on the returned List<string>
- the setter is not invoked.
For a new document: Settings -> Preferences -> New Document/Default Directory
-> New Document -> Format -> Windows/Mac/Unix
And for an already-open document: Edit -> EOL Conversion
On mac, open the terminal and type:
cd /usr/local/mysql/bin
then type:
./mysql -u root -p
It will ask you for the mysql root password. Enter your password and use mysql database in the terminal.
really interesting problem, haven't seen it yet. this code works fine for me. tested it in chrome and IE9
