OFFSET
is nothing but a keyword to indicate starting cursor in table
SELECT column FROM table LIMIT 18 OFFSET 8 -- fetch 18 records, begin with record 9 (OFFSET 8)
you would get the same result form
SELECT column FROM table LIMIT 8, 18
visual representation (R
is one record in the table in some order)
OFFSET LIMIT rest of the table

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".
/// <summary>
/// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not
/// let the JsonProperty control everything.
/// </summary>
/// <typeparam name="T"></typeparam>
public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
{
private Dictionary<string, string> PropertyMappings { get; set; }
public IgnoreJsonPropertyResolver()
{
this.PropertyMappings = new Dictionary<string, string>();
var properties = ReflectionHelper<T>.GetGetProperties(false)();
foreach (var propertyInfo in properties)
{
var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
if (jsonProperty != null)
{
PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
}
}
}
protected override string ResolvePropertyName(string propertyName)
{
string resolvedName = null;
var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
}
}
Usage:
var settings = new JsonSerializerSettings();
settings.DateFormatString = "YYYY-MM-DD";
settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
var model = new PlanViewModel() {Amount = 100};
var strModel = JsonConvert.SerializeObject(model,settings);
Model:
public class PlanViewModel
{
/// <summary>
/// The customer is charged an amount over an interval for the subscription.
/// </summary>
[JsonProperty(PropertyName = "RecurringPrice")]
public double Amount { get; set; }
/// <summary>
/// Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
/// months or years depending on the value for interval_unit.
/// </summary>
public int Interval { get; set; } = 1;
/// <summary>
/// Number of free trial days that can be granted when a customer is subscribed to this plan.
/// </summary>
public int TrialPeriod { get; set; } = 30;
/// <summary>
/// This indicates a one-time fee charged upfront while creating a subscription for this plan.
/// </summary>
[JsonProperty(PropertyName = "SetupFee")]
public double SetupAmount { get; set; } = 0;
/// <summary>
/// String representing the type id, usually a lookup value, for the record.
/// </summary>
[JsonProperty(PropertyName = "TypeId")]
public string Type { get; set; }
/// <summary>
/// Billing Frequency
/// </summary>
[JsonProperty(PropertyName = "BillingFrequency")]
public string Period { get; set; }
/// <summary>
/// String representing the type id, usually a lookup value, for the record.
/// </summary>
[JsonProperty(PropertyName = "PlanUseType")]
public string Purpose { get; set; }
}
Or you can do
public class Person
{
public Person(int id)
{
this.Id=id;
}
public string Name { get; set; }
public int Id { get; private set; }
public int Age { get; set; }
}
I'd start by using glob:
from PIL import Image
import glob
image_list = []
for filename in glob.glob('yourpath/*.gif'): #assuming gif
im=Image.open(filename)
image_list.append(im)
then do what you need to do with your list of images (image_list).

I hope you Find Right solution here.
Thanks.
If you want to set the "1234" button, you need to use its "id":
document.getElementById("_1234").checked = true;
When you're using the browser API ("getElementById"), you don't use selector syntax; you just pass the actual "id" value you're looking for. You use selector syntax with jQuery or .querySelector()
and .querySelectorAll()
.
I use the counter variable like Fink suggests. If you want For Each and to pass ByRef (which can be more efficient for long strings) you have to cast your element as a string using CStr
Sub Example()
Dim vItm As Variant
Dim aStrings(1 To 4) As String
aStrings(1) = "one": aStrings(2) = "two": aStrings(3) = "three": aStrings(4) = "four"
For Each vItm In aStrings
do_something CStr(vItm)
Next vItm
End Sub
Function do_something(ByRef sInput As String)
Debug.Print sInput
End Function
After doing many tests in Litmus, i could not find a way to have perfect rendering in all emails readers, but here is the better solution i found :
<table width="100%" cellpadding="0" cellspacing="0" style="background-color:#333;color:#fff;border-radius:3px;border-spacing:0;" >
<tr>
<td style="width:12px;" > </td>
<td valign="middle" style="padding-top:6px;padding-bottom:6px;padding-right:0;padding-left:0;" >
<span style="color:#fff;" ><strong>Your text here</strong> and here</span></a>
</td>
<td style="width:12px;" > </td>
</tr>
</table>
In this piece of code, i aimed to emulate padding : 6px 12px;
There are 2 "12px table columns" that handles the right and left padding.
And I'm using "padding: 6px 0;" on my td content, to manage top and bottom padding : Outlook 2010 and 2013 will ignore this and will use their own padding.
The text won't be perfectly aligned in Outlook 2010 and Outlook 2013 (slightly too far from top) but it works with all other email readers i tried : Apple Mail, Gmail, Outlook 2011 (yes..), Hotmail, Yahoo and many more.

As others have said #4 is the best method when not using a library method. However you should always put null on the left side of the comparison to ensure you don't accidentally assign null to foo in case of typo. In that case the compiler will catch the mistake.
// You meant to do this
if(foo != null){
// But you made a typo like this which will always evaluate to true
if(foo = null)
// Do the comparison in this way
if(null != foo)
// So if you make the mistake in this way the compiler will catch it
if(null = foo){
// obviously the typo is less obvious when doing an equality comparison but it's a good habit either way
if(foo == null){
if(foo = null){
Use the wait
built-in:
process1 &
process2 &
process3 &
process4 &
wait
process5 &
process6 &
process7 &
process8 &
wait
For the above example, 4 processes process1
... process4
would be started in the background, and the shell would wait until those are completed before starting the next set.
From the GNU manual:
wait [jobspec or pid ...]
Wait until the child process specified by each process ID pid or job specification jobspec exits and return the exit status of the last command waited for. If a job spec is given, all processes in the job are waited for. If no arguments are given, all currently active child processes are waited for, and the return status is zero. If neither jobspec nor pid specifies an active child process of the shell, the return status is 127.
git merge

If working on EJB client library:
You need to mention the argument for getting the initial context.
InitialContext ctx = new InitialContext();
If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext ctx = new InitialContext(props);
URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.
The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.
var thisRegex = new RegExp('\[(\d+)\]\[(\d+)\]');
if(!thisRegex.test(text)){
alert('fail');
}
I found test to act more preg_match as it provides a Boolean return. However you do have to declare a RegExp var.
TIP: RegExp adds it's own / at the start and finish, so don't pass them.
just simple replace your class with this.
.ui-page

I have same issue and i solved it.
I had to look for them in C:\Users\Dell\AppData\Local\Arduino15\
I had to take help from the "date created" and "date modified" attributes to identify which libraries to delete.
But the names still show in the IDE... But it is something I can live with for now.
You can use a custom serializer at your money field. Here's an example with a MoneyBean. The field amount gets annotated with @JsonSerialize(using=...).
public class MoneyBean {
//...
@JsonProperty("amountOfMoney")
@JsonSerialize(using = MoneySerializer.class)
private BigDecimal amount;
//getters/setters...
}
public class MoneySerializer extends JsonSerializer<BigDecimal> {
@Override
public void serialize(BigDecimal value, JsonGenerator jgen, SerializerProvider provider) throws IOException,
JsonProcessingException {
// put your desired money style here
jgen.writeString(value.setScale(2, BigDecimal.ROUND_HALF_UP).toString());
}
}
That's it. A BigDecimal is now printed in the right way. I used a simple testcase to show it:
@Test
public void jsonSerializationTest() throws Exception {
MoneyBean m = new MoneyBean();
m.setAmount(new BigDecimal("20.3"));
ObjectMapper mapper = new ObjectMapper();
assertEquals("{\"amountOfMoney\":\"20.30\"}", mapper.writeValueAsString(m));
}
INSERT INTO DB1.dbo.TempTable
SELECT * FROM DB2.dbo.TempTable
If we use this query it will return Primary key error
.... So better to choose which columns need to be moved, like
INSERT INTO db1.dbo.TempTable // (List of columns here)
SELECT (Same list of columns here)
FROM db2.dbo.TempTable
You forgot @Service annotation in your service class.
Arguments
property in Execute Process Task available on the Control Flow tab is expecting a value of data type DT_WSTR
and not DT_STR
.
Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_13177007.dtsx
. Create a package variable with the following information.
Name Scope Data Type Value
------ ------------ ---------- -----
IdVar SO_13177007 Int32 123
Drag and drop an Execute Process Task onto the Control Flow tab and name it as Pass arguments
Double-click the Execute Process Task to open the Execute Process Task Editor
. Click Expressions page and then click the Ellipsis button against the Expressions property to view the Property Expression Editor
.
On the Property Expression Editor, select the property Arguments
and click the Ellipsis button against the property to open the Expression Builder
.
On the Expression Builder, enter the following expression and click Evaluate Expression
. This expression tries to convert the integer value in the variable IdVar
to string data type.
(DT_STR, 10, 1252) @[User::IdVar]
Clicking Evaluate Expression will display the following error message because the Arguments property on Execute Process Task expects a value of data type DT_WSTR
.
To fix the issue, update the expression as shown below to convert the integer value to data type DT_WSTR
. Clicking Evaluate Expression will display the value in the Evaluated value text area.
(DT_WSTR, 10) @[User::IdVar]
To understand the differences between the data types DT_STR
and DT_WSTR
in SSIS, read the documentation Integration Services Data Types on MSDN. Here are the quotes from the documentation about these two string data types.
A null-terminated ANSI/MBCS character string with a maximum length of 8000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
A null-terminated Unicode character string with a maximum length of 4000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)
First, you need to decode it :
$jsonString = file_get_contents('jsonFile.json');
$data = json_decode($jsonString, true);
Then change the data :
$data[0]['activity_name'] = "TENNIS";
// or if you want to change all entries with activity_code "1"
foreach ($data as $key => $entry) {
if ($entry['activity_code'] == '1') {
$data[$key]['activity_name'] = "TENNIS";
}
}
Then re-encode it and save it back in the file:
$newJsonString = json_encode($data);
file_put_contents('jsonFile.json', $newJsonString);
You probably want to use something like jQuery, which makes JS programming easier.
Something like:
$(document).ready(function(){
// Your code here
});
Would seem to do what you are after.
I'm late to the party here, but there's an awesome library I've been using which I haven't seen referenced in the other answers
https://github.com/brminnick/AsyncAwaitBestPractices
If you need to "Fire And Forget" you call the extension method on the task.
Passing the action onException to the call ensures that you get the best of both worlds - no need to await execution and slow your users down, whilst retaining the ability to handle the exception in a graceful manner.
In your example you would use it like this:
public string GetStringData()
{
MyAsyncMethod().SafeFireAndForget(onException: (exception) =>
{
//DO STUFF WITH THE EXCEPTION
});
return "hello world";
}
It also gives awaitable AsyncCommands implementing ICommand out the box which is great for my MVVM Xamarin solution
TLS 1.2
is only supported since OpenSSL 1.0.1
(see the Major version releases section), you have to update your OpenSSL
.
It is not necessary to set the CURLOPT_SSLVERSION
option. The request involves a handshake which will apply the newest TLS
version both server and client support. The server you request is using TLS 1.2
, so your php_curl
will use TLS 1.2
(by default) as well if your OpenSSL
version is (or newer than) 1.0.1
.
I have published a header file to perform the switch on the strings in C. It contains a set of macro that hide the call to the strcmp() (or similar) in order to mimic a switch-like behaviour. I have tested it only with GCC in Linux, but I'm quite sure that it can be adapted to support other environment.
EDIT: added the code here, as requested
This is the header file you should include:
#ifndef __SWITCHS_H__
#define __SWITCHS_H__
#include <string.h>
#include <regex.h>
#include <stdbool.h>
/** Begin a switch for the string x */
#define switchs(x) \
{ char *__sw = (x); bool __done = false; bool __cont = false; \
regex_t __regex; regcomp(&__regex, ".*", 0); do {
/** Check if the string matches the cases argument (case sensitive) */
#define cases(x) } if ( __cont || !strcmp ( __sw, x ) ) \
{ __done = true; __cont = true;
/** Check if the string matches the icases argument (case insensitive) */
#define icases(x) } if ( __cont || !strcasecmp ( __sw, x ) ) { \
__done = true; __cont = true;
/** Check if the string matches the specified regular expression using regcomp(3) */
#define cases_re(x,flags) } regfree ( &__regex ); if ( __cont || ( \
0 == regcomp ( &__regex, x, flags ) && \
0 == regexec ( &__regex, __sw, 0, NULL, 0 ) ) ) { \
__done = true; __cont = true;
/** Default behaviour */
#define defaults } if ( !__done || __cont ) {
/** Close the switchs */
#define switchs_end } while ( 0 ); regfree(&__regex); }
#endif // __SWITCHS_H__
And this is how you use it:
switchs(argv[1]) {
cases("foo")
cases("bar")
printf("foo or bar (case sensitive)\n");
break;
icases("pi")
printf("pi or Pi or pI or PI (case insensitive)\n");
break;
cases_re("^D.*",0)
printf("Something that start with D (case sensitive)\n");
break;
cases_re("^E.*",REG_ICASE)
printf("Something that start with E (case insensitive)\n");
break;
cases("1")
printf("1\n");
// break omitted on purpose
cases("2")
printf("2 (or 1)\n");
break;
defaults
printf("No match\n");
break;
} switchs_end;
Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct()
. Otherwise you get one user multiple times:
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()
The Best way i Found to do that is this. You can remove my HTML and place yours there.
$('.home-banner-slider').slick({
dots: false,
infinite: true,
autoplay: true,
autoplaySpeed: 3000,
speed: 300,
slidesToScroll: 1,
arrows: true,
prevArrow: '<div class="slick-prev"><i class="fa fa-angle-left" aria-hidden="true"></i></div>',
nextArrow: '<div class="slick-next"><i class="fa fa-angle-right" aria-hidden="true"></i></div>'
});
You can solve this problem using this code:
if(!empty($_GET['variable from which you get']))
{
$_SESSION['something']= $_GET['variable from which you get'];
}
So you get the variable from a GET form, you will store in the $_SESSION['whatever']
variable just once when $_GET['variable from which you get']
is set and if it is empty $_SESSION['something']
will store the old parameter
You can observe softkeyboard's hide by using activity's decorView.
public final class SoftKeyboardUtil {
public static final String TAG = "SoftKeyboardUtil";
public static void observeSoftKeyBoard(Activity activity , final OnSoftKeyBoardHideListener listener){
final View decorView = activity.getWindow().getDecorView();
decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect rect = new Rect();
decorView.getWindowVisibleDisplayFrame(rect);
int displayHight = rect.bottom - rect.top;
int hight = decorView.getHeight();
boolean hide = (double)displayHight / hight > 0.8 ;
if(Log.isLoggable(TAG, Log.DEBUG)){
Log.d(TAG ,"DecorView display hight = "+displayHight);
Log.d(TAG ,"DecorView hight = "+ hight);
Log.d(TAG, "softkeyboard visible = " + !hide);
}
listener.onSoftKeyBoardVisible(!hide);
}
});
}
public interface OnSoftKeyBoardHideListener{
void onSoftKeyBoardVisible(boolean visible);
}
}
How about like this:
char* cmd = "./foo 1 2 3";
system(cmd);
You can use something like this: Arrays#copyOfRange
int arr[10] = {0, 5, 3, 64};
arr[4] = 5;
EDIT: So I was asked to explain what's happening when you do:
int arr[10] = {0, 5, 3, 64};
you create an array with 10 elements and you allocate values for the first 4 elements of the array.
Also keep in mind that arr
starts at index arr[0]
and ends at index arr[9]
- 10 elements
arr[0] has value 0;
arr[1] has value 5;
arr[2] has value 3;
arr[3] has value 64;
after that the array contains garbage values / zeroes because you didn't allocated any other values
But you could still allocate 6 more values so when you do
arr[4] = 5;
you allocate the value 5 to the fifth element of the array.
You could do this until you allocate values for the last index of the arr
that is arr[9]
;
Sorry if my explanation is choppy, but I have never been good at explaining things.
This is a straight way to do this.
The case is simple, but finally quite common ( typical thumbnails scroller with fixed cell size and fixed gap between cells )
var itemCellSize: CGSize = <your cell size>
var itemCellsGap: CGFloat = <gap in between>
override func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
let pageWidth = (itemCellSize.width + itemCellsGap)
let itemIndex = (targetContentOffset.pointee.x) / pageWidth
targetContentOffset.pointee.x = round(itemIndex) * pageWidth - (itemCellsGap / 2)
}
// CollectionViewFlowLayoutDelegate
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return itemCellSize
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
return itemCellsGap
}
Note that there is no reason to call a scrollToOffset or dive into layouts. The native scrolling behaviour already does everything.
Cheers All :)

$.params = window.location.href.split("/"); $.params[$.params.length-1];
You can split based on your query string separator
This is one of the most commonly asked question to obtain the paginated result and the total number of results simultaneously in single query. I can't explain how I felt when I finally achieved it LOL.
$result = $collection->aggregate(array(
array('$match' => $document),
array('$group' => array('_id' => '$book_id', 'date' => array('$max' => '$book_viewed'), 'views' => array('$sum' => 1))),
array('$sort' => $sort),
// get total, AND preserve the results
array('$group' => array('_id' => null, 'total' => array( '$sum' => 1 ), 'results' => array( '$push' => '$$ROOT' ) ),
// apply limit and offset
array('$project' => array( 'total' => 1, 'results' => array( '$slice' => array( '$results', $skip, $length ) ) ) )
))
Result will look something like this:
[
{
"_id": null,
"total": ...,
"results": [
{...},
{...},
{...},
]
}
]

There is no need to invoke PHP for this. Just put it directly into the HTML:
<a href="http://www.example.com/">...
You don't need to use setAttribute for that - This code works (IE8 also)
<div id="something" >Hello</div>
<script type="text/javascript" >
(function() {
document.getElementById("something").onclick = function() {
alert('hello');
};
})();
</script>
This one worked for me:
In Activity:
User user;
public User getUser(){ return this.user;}
In Fragment's onCreateView method:
User user = ((MainActivity)getActivity()).getUser();
Replace the MainActivity
with your Activity Name.
If conditions is the best way to do it. If u want the count use pivot table of buckets. It's the easiest way and the if conditions can go for more than 5-6 buckets too
In Swift
let alertController = UIAlertController(title:"Title", message: "Message", preferredStyle:.alert)
let Action = UIAlertAction.init(title: "Ok", style: .default) { (UIAlertAction) in
// Write Your code Here
}
alertController.addAction(Action)
self.present(alertController, animated: true, completion: nil)
In Objective C
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *OK = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action)
{
}];
[alertController addAction:OK];
[self presentViewController:alertController animated:YES completion:nil];
A much easier solution
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

Using jQuery's .is( ":focus" )
$(".status").on("click","textarea",function(){
if ($(this).is( ":focus" )) {

This can also be done as follows for a list of dataframes df_list
:
df = df_list[0]
for df_ in df_list[1:]:
df = df.merge(df_, on='join_col_name')
or if the dataframes are in a generator object (e.g. to reduce memory consumption):
df = next(df_list)
for df_ in df_list:
df = df.merge(df_, on='join_col_name')
You have to calculate the scale that you need to use manually, rather than setting to 30.
private int getScale(){
Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();

I'd suggest using a pseudo element in place of the overlay element. Because pseudo elements can't be added on enclosed img
elements, you would still need to wrap the img
element though.
LIVE EXAMPLE HERE -- EXAMPLE WITH TEXT
<div class="image">
<img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>
As for the CSS, set optional dimensions on the .image
element, and relatively position it. If you are aiming for a responsive image, just omit the dimensions and this will still work (example). It's just worth noting that the dimensions must be on the parent element as opposed to the img
element itself, see.
.image {
position: relative;
width: 400px;
height: 400px;
}
Give the child img
element a width of 100%
of the parent and add vertical-align:top
to fix the default baseline alignment issues.
.image img {
width: 100%;
vertical-align: top;
}
As for the pseudo element, set a content value and absolutely position it relative to the .image
element. A width/height of 100%
will ensure that this works with varying img
dimensions. If you want to transition the element, set an opacity of 0
and add the transition properties/values.
.image:after {
content: '\A';
position: absolute;
width: 100%; height:100%;
top:0; left:0;
background:rgba(0,0,0,0.6);
opacity: 0;
transition: all 1s;
-webkit-transition: all 1s;
}
Use an opacity of 1
when hovering over the pseudo element in order to facilitate the transition:
.image:hover:after {
opacity: 1;
}
For the simplest approach, just add the text as the pseudo element's content
value:
.image:after {
content: 'Here is some text..';
color: #fff;
/* Other styling.. */
}
That should work in most instances; however, if you have more than one img
element, you might not want the same text to appear on hover. You could therefore set the text in a data-*
attribute and therefore have unique text for every img
element.
.image:after {
content: attr(data-content);
color: #fff;
}
With a content
value of attr(data-content)
, the pseudo element adds the text from the .image
element's data-content
attribute:
<div data-content="Text added on hover" class="image">
<img src="http://i.stack.imgur.com/Sjsbh.jpg" alt="" />
</div>
You can add some styling and do something like this:
In the above example, the :after
pseudo element serves as the black overlay, while the :before
pseudo element is the caption/text. Since the elements are independent of each other, you can use separate styling for more optimal positioning.
.image:after, .image:before {
position: absolute;
opacity: 0;
transition: all 0.5s;
-webkit-transition: all 0.5s;
}
.image:after {
content: '\A';
width: 100%; height:100%;
top: 0; left:0;
background:rgba(0,0,0,0.6);
}
.image:before {
content: attr(data-content);
width: 100%;
color: #fff;
z-index: 1;
bottom: 0;
padding: 4px 10px;
text-align: center;
background: #f00;
box-sizing: border-box;
-moz-box-sizing:border-box;
}
.image:hover:after, .image:hover:before {
opacity: 1;
}
In SQL server there is no way to delete multiple tables using join. So you have to delete from child first before delete form parent.
In case the dictionaries are only uniquely identified by all items (ID is not available) you can use the answer using JSON. The following is an alternative that does not use JSON, and will work as long as all dictionary values are immutable
[dict(s) for s in set(frozenset(d.items()) for d in L)]
I got the following error
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
Tried several ways and finally solved it through the following way
sudo gksu gedit /etc/mysql/my.cnf
modified
#bind-address = 127.0.0.1
to
bind-address = localhost
and restarted
sudo /etc/init.d/mysql restart
it worked
You can also use
./gradlew clean build
(Mac and Linux) -With ./
gradlew clean build
(Windows) -Without ./
it removes build folder, as well configure your modules and then build your project.
i use it before release any new app on playstore.
Overloading methods is tricky in Python. However, there could be usage of passing the dict, list or primitive variables.
I have tried something for my use cases, and this could help here to understand people to overload the methods.
Let's take your example:
A class overload method with call the methods from different class.
def add_bullet(sprite=None, start=None, headto=None, spead=None, acceleration=None):
Pass the arguments from the remote class:
add_bullet(sprite = 'test', start=Yes,headto={'lat':10.6666,'long':10.6666},accelaration=10.6}
Or
add_bullet(sprite = 'test', start=Yes, headto={'lat':10.6666,'long':10.6666},speed=['10','20,'30']}
So, handling is being achieved for list, Dictionary or primitive variables from method overloading.
Try it out for your code.
Edit: The issue addressed in this answer have been resolved in angular.js version 1.2.7. $broadcast
now avoids bubbling over unregistered scopes and runs just as fast as $emit.
So, now you can:
$broadcast
from the $rootScope
$on
from the local $scope
that needs to know about the eventOriginal Answer Below
I highly advise not to use $rootScope.$broadcast
+ $scope.$on
but rather $rootScope.$emit
+ $rootScope.$on
. The former can cause serious performance problems as raised by @numan. That is because the event will bubble down through all scopes.
However, the latter (using $rootScope.$emit
+ $rootScope.$on
) does not suffer from this and can therefore be used as a fast communication channel!
From the angular documentation of $emit
:
Dispatches an event name upwards through the scope hierarchy notifying the registered
Since there is no scope above $rootScope
, there is no bubbling happening. It is totally safe to use $rootScope.$emit()
/ $rootScope.$on()
as an EventBus.
However, there is one gotcha when using it from within Controllers. If you directly bind to $rootScope.$on()
from within a controller, you'll have to clean up the binding yourself when your local $scope
gets destroyed. This is because controllers (in contrast to services) can get instantiated multiple times over the lifetime of an application which would result into bindings summing up eventually creating memory leaks all over the place :)
To unregister, just listen on your $scope
's $destroy
event and then call the function that was returned by $rootScope.$on
.
angular
.module('MyApp')
.controller('MyController', ['$scope', '$rootScope', function MyController($scope, $rootScope) {
var unbind = $rootScope.$on('someComponent.someCrazyEvent', function(){
console.log('foo');
});
$scope.$on('$destroy', unbind);
}
]);
I would say, that's not really an angular specific thing as it applies to other EventBus implementations as well, that you have to clean up resources.
However, you can make your life easier for those cases. For instance, you could monkey patch $rootScope
and give it a $onRootScope
that subscribes to events emitted on the $rootScope
but also directly cleans up the handler when the local $scope
gets destroyed.
The cleanest way to monkey patch the $rootScope
to provide such $onRootScope
method would be through a decorator (a run block will probably do it just fine as well but pssst, don't tell anybody)
To make sure the $onRootScope
property doesn't show up unexpected when enumerating over $scope
we use Object.defineProperty()
and set enumerable
to false
. Keep in mind that you might need an ES5 shim.
angular
.module('MyApp')
.config(['$provide', function($provide){
$provide.decorator('$rootScope', ['$delegate', function($delegate){
Object.defineProperty($delegate.constructor.prototype, '$onRootScope', {
value: function(name, listener){
var unsubscribe = $delegate.$on(name, listener);
this.$on('$destroy', unsubscribe);
return unsubscribe;
},
enumerable: false
});
return $delegate;
}]);
}]);
With this method in place the controller code from above can be simplified to:
angular
.module('MyApp')
.controller('MyController', ['$scope', function MyController($scope) {
$scope.$onRootScope('someComponent.someCrazyEvent', function(){
console.log('foo');
});
}
]);
So as a final outcome of all this I highly advise you to use $rootScope.$emit
+ $scope.$onRootScope
.
Btw, I'm trying to convince the angular team to address the problem within angular core. There's a discussion going on here: https://github.com/angular/angular.js/issues/4574
Here is a jsperf that shows how much of a perf impact $broadcast
brings to the table in a decent scenario with just 100 $scope
's.
When using an iframe, you will first have to switch to the iframe, before selecting the elements of that iframe
You can do it using:
driver.switchTo().frame(driver.findElement(By.id("frameId")));
//do your stuff
driver.switchTo().defaultContent();
In case if your frameId is dynamic, and you only have one iframe, you can use something like:
driver.switchTo().frame(driver.findElement(By.tagName("iframe")));
Haven't tried it myself, but this page has a list of plugin modules that run in Linux' built in iptables IP filtering system. One of the modules is called "nth", and allows you to set up a rule that will drop a configurable rate of the packets. Might be a good place to start, at least.
You can set the year range using this option per documentation here http://api.jqueryui.com/datepicker/#option-yearRange
yearRange: '1950:2013', // specifying a hard coded year range
or this way
yearRange: "-100:+0", // last hundred years
From the Docs
Default: "c-10:c+10"
The range of years displayed in the year drop-down: either relative to today's year ("-nn:+nn"), relative to the currently selected year ("c-nn:c+nn"), absolute ("nnnn:nnnn"), or combinations of these formats ("nnnn:-nn"). Note that this option only affects what appears in the drop-down, to restrict which dates may be selected use the minDate and/or maxDate options.
Code:
test = {'a': 1, 'c': {'a': 2, 'b': {'x': 5, 'y' : 10}}, 'd': [1, 2, 3]}
def parse_dict(init, lkey=''):
ret = {}
for rkey,val in init.items():
key = lkey+rkey
if isinstance(val, dict):
ret.update(parse_dict(val, key+'_'))
else:
ret[key] = val
return ret
print(parse_dict(test,''))
Results:
$ python test.py
{'a': 1, 'c_a': 2, 'c_b_x': 5, 'd': [1, 2, 3], 'c_b_y': 10}

If you have a LDAP connection with a username and password to connect to Active Directory, here is the code I used to connect properly:
using System.DirectoryServices.AccountManagement;
// ...
// Connection information
var connectionString = "LDAP://domain.com/DC=domain,DC=com";
var connectionUsername = "your_ad_username";
var connectionPassword = "your_ad_password";
// Get groups for this user
var username = "myusername";
// Split the LDAP Uri
var uri = new Uri(connectionString);
var host = uri.Host;
var container = uri.Segments.Count() >=1 ? uri.Segments[1] : "";
// Create context to connect to AD
var princContext = new PrincipalContext(ContextType.Domain, host, container, connectionUsername, connectionPassword);
// Get User
UserPrincipal user = UserPrincipal.FindByIdentity(princContext, IdentityType.SamAccountName, username);
// Browse user's groups
foreach (GroupPrincipal group in user.GetGroups())
{
Console.Out.WriteLine(group.Name);
}
I think you might be able to use the ExpandProperty
parameter of Select-Object
.
For example, to get the list of the current directory and just have the Name property displayed, one would do the following:
ls | select -Property Name
This is still returning DirectoryInfo or FileInfo objects. You can always inspect the type coming through the pipeline by piping to Get-Member (alias gm
).
ls | select -Property Name | gm
So, to expand the object to be that of the type of property you're looking at, you can do the following:
ls | select -ExpandProperty Name
In your case, you can just do the following to have a variable be an array of strings, where the strings are the Name property:
$objects = ls | select -ExpandProperty Name
Try this:
foreach($array as $k => $obj) {
$obj->{'newKey'} = "value";
}
This is official recommendation for upgrading Tensorflow.
To get TensorFlow 1.5, you can use the standard pip installation (or pip3 if you use python3)
$ pip install --ignore-installed --upgrade tensorflow
Define 'better'. A synchronized block is only better because it allows you to:
Now your specific example is an example of the double-checked locking pattern which is suspect (in older Java versions it was broken, and it is easy to do it wrong).
If your initialization is cheap, it might be better to initialize immediately with a final field, and not on the first request, it would also remove the need for synchronization.
I like List comprehensions because of their Math (Set) syntax. So how about this:
L = [1, 2, 3, 4, 5, 6, 7]
odd_numbers = [y for x,y in enumerate(L) if x%2 != 0]
even_numbers = [y for x,y in enumerate(L) if x%2 == 0]
Basically, if you enumerate over a list, you'll get the index x
and the value y
. What I'm doing here is putting the value y
into the output list (even or odd) and using the index x
to find out if that point is odd (x%2 != 0
).
In case you want to improve the commit message with header and body after you created the commit, you can reword it. This approach is more useful because you know what the code does only after you wrote it.
git rebase -i origin/master
Then, your commits will appear:
pick e152ce2 Update framework
pick ffcf91e Some magic
pick fa672e1 Update comments
Select the commit you want to reword and save.
pick e152ce2 Update framework
reword ffcf91e Some magic
pick fa672e1 Update comments
Now, you have the opportunity to add header and body, where the first line will be the header.

How to hard reset Visual Studio instance
When developing extensions sometimes you just mess up, others someone else does. If you start getting errors loading even the most mundane extensions, these are the instructions to hard reset your instance.
Close Visual Studio (if you haven’t already).
Open the registry editor (regedit.exe)
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}_Config
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\{version} directory.
Enjoy your brand new Visual Studio instance.
If on the other side you want to reset the experimental hive you can do the same to with the ‘{version}Exp’ ones.
Happy coding!

The best approach depends on what you want to do:
So, just to get this right, the advantage of a interface is that I can separate the calling of a method from any particular class. Instead creating a instance of the interface, where the implementation is given from whichever class I choose that implements that interface. Thus allowing me to have many classes, which have similar but slightly different functionality and in some cases (the cases related to the intention of the interface) not care which object it is.
For example, I could have a movement interface. A method which makes something 'move' and any object (Person, Car, Cat) that implements the movement interface could be passed in and told to move. Without the method every knowing the type of class it is.
The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options
value as a default.
As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.
Mathematica or Maple will allow you to give as many decimal places as your heart desires.
EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.
On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin
(usually 2e-308).
Compare these two analyses.
x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1) #Should throw an error
x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2) #ok
In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.
As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr
package.
mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")
These are slower and more memory intensive to use than regular (double precision) numeric
vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.
Downcasting is allowed when there is a possibility that it succeeds at run time:
Object o = getSomeObject(),
String s = (String) o; // this is allowed because o could reference a String
In some cases this will not succeed:
Object o = new Object();
String s = (String) o; // this will fail at runtime, because o doesn't reference a String
When a cast (such as this last one) fails at runtime a ClassCastException
will be thrown.
In other cases it will work:
Object o = "a String";
String s = (String) o; // this will work, since o references a String
Note that some casts will be disallowed at compile time, because they will never succeed at all:
Integer i = getSomeInteger();
String s = (String) i; // the compiler will not allow this, since i can never reference a String.
From Avinash Kumar Pankaj's example
View v;
then at oncreate method
v = new View(getActivity());
and then onlistitemclick method i wrote
public void onListItemClick(ListView listView, View view, int position,
long id) {
v.setBackgroundResource(0);
view.setBackgroundResource(R.color.green);
v = view;
}
It worked for me. Thank you.
I replaced
v = new View(getActivity());
to
v = new View(this);
and the code worked well.
It is necessary the xml files 'colors' and 'bg_key' from previous examples too, as well as ListView attribute android:background="@drawable/bg_key"

With dplyr 0.7.2
, you can use the very useful case_when
function :
x=read.table(
text="V1 V2 V3 V4
1 1 2 3 5
2 2 4 4 1
3 1 4 1 1
4 4 5 1 3
5 5 5 5 4")
x$V5 = case_when(x$V1==1 & x$V2!=4 ~ 1,
x$V2==4 & x$V3!=1 ~ 2,
TRUE ~ 0)
Expressed with dplyr::mutate
, it gives:
x = x %>% mutate(
V5 = case_when(
V1==1 & V2!=4 ~ 1,
V2==4 & V3!=1 ~ 2,
TRUE ~ 0
)
)
Please note that NA
are not treated specially, as it can be misleading. The function will return NA
only when no condition is matched. If you put a line with TRUE ~ ...
, like I did in my example, the return value will then never be NA
.
Therefore, you have to expressively tell case_when
to put NA
where it belongs by adding a statement like is.na(x$V1) | is.na(x$V3) ~ NA_integer_
. Hint: the dplyr::coalesce()
function can be really useful here sometimes!
Moreover, please note that NA
alone will usually not work, you have to put special NA
values : NA_integer_
, NA_character_
or NA_real_
.
I think you could do it by creating parameters in an object maybe?
var myObject = {}; for(var i=0;i<myArray.length;i++) { myObject[ myArray[i] ]; }
If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.
You might be able to get them like this:
def thr = Thread.currentThread()
def build = thr?.executable
def envVarsMap = build.parent.builds[0].properties.get("envVars")
I resolve this with this way:
$autoload['model'] = array('Page_model'=>'page');
Works fine.. I hope help.
Typically on Debian systems you have different PHP configuration for CLI and for PHP running as say an Apache module. Your phpinfo page may very well show simplexml as being enabled via web server, while it is not enabled via CLI.
Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax()
method. Or if you wanted to do it using plain javascript, here's a tutorial.

In Python 2.x another approach is to use map
:
numbers = map(int, numbers)
Note: in Python 3.x map
returns a map object which you can convert to a list if you want:
numbers = list(map(int, numbers))

Here is another way to drop all tables correctly, using sp_MSdropconstraints
procedure. The shortest code I could think of:
exec sp_MSforeachtable "declare @name nvarchar(max); set @name = parsename('?', 1); exec sp_MSdropconstraints @name";
exec sp_MSforeachtable "drop table ?";
If you did literally this:
encodeURIComponent('&')
Then the result is %26
, you can test it here. Make sure the string you are encoding is just &
and not &
to begin with...otherwise it is encoding correctly, which is likely the case. If you need a different result for some reason, you can do a .replace(/&/g,'&')
before the encoding.
Personally, I would fix this in the .htaccess file. You should have access to that.

RewriteRule ^image_dir/(.*) images/$1

customer.Ord.push(cells[2]);
customer.Point_ID = cells[3];
customer.Point_Name = cells[4];
customer.Point_Type = cells[5];
customer.Set_ORD = cells[6];
customers.push(customer);

You can also use the Package Manager Console and invoke the Install-Package
cmdlet by specifying the path to the directory that contains the package file in the -Source
parameter:
Install-Package SomePackage -Source C:\PathToThePackageDir\
Try using step="0.01"
, then it will step by a penny each time.
eg:
<input type="number" min="0.00" max="10000.00" step="0.01" />

HTML : Pass the whole body inside on click
div class="calculate" id="calculate">
<div class="button" id="button" onclick="myCode(this.body)"> CALCULATE ! </div>
</div>
Then write the JavaScript code inside the function "myCode()"
function myCode()
{
var bill = document.getElementById("currency").value ;
var people_count = document.getElementById("number1").value;
var select_value = document.getElementById("select").value;
var calculate = document.getElementById("calculate");
calculate.addEventListener("click" ,function()
{
console.log(bill);
console.log(people_count);
console.log(select_value);
});
}
you will get your values I am using visual studio code editor
You can use groups (indicated with '('
and ')'
) to capture parts of the string. The match object's group()
method then gives you the group's contents:
>>> import re
>>> s = 'name my_user_name is valid'
>>> match = re.search('name (.*) is valid', s)
>>> match.group(0) # the entire match
'name my_user_name is valid'
>>> match.group(1) # the first parenthesized subgroup
'my_user_name'
In Python 3.6+ you can also index into a match object instead of using group()
:
>>> match[0] # the entire match
'name my_user_name is valid'
>>> match[1] # the first parenthesized subgroup
'my_user_name'
It supports after KITKAT. Just add following code inside onCreate method of your Activity. No need any modifications to Manifest file.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow(); // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
You can use result.className = 'red';
, but you can also use result.classList.add('red');
. The .classList.add(str)
way is usually easier if you need to add a class in general, and don't want to check if the class is already in the list of classes.
You should have a 'skeleton' somewhere in /etc
, probably /etc/skeleton
, or check the default settings, probably /etc/default
or something. Those are scripts that define standard environment variables getting set during a login.
If it is just for your own account: check the (hidden) file ~/.profile
and ~/.login
. Or generate them, if they don't exist. These are also evaluated by the login process.
Another scenario that can cause this exception is with DataBinding, that is when you use something like this in your layout
<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
<data>
<variable
name="model"
type="point.to.your.model"/>
</data>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="@{model.someIntegerVariable}"/>
</layout>
Notice that the variable I'm using is an Integer and I'm assigning it to the text field of the TextView. Since the TextView already has a method with signature of setText(int)
it will use this method instead of using the setText(String)
and cast the value. Thus the TextView thinks of your input number as a resource value which obviously is not valid.
Solution is to cast your int value to string like this
android:text="@{String.valueOf(model.someIntegerVariable)}"
If you just don't need anything as your type, you can use void. This can be used for implementing functions, or actions. You could then do something like this:
interface Action<T> {
public T execute();
}
abstract class VoidAction implements Action<Void> {
public Void execute() {
executeInternal();
return null;
}
abstract void executeInternal();
}
Or you could omit the abstract class, and do the return null in every action that doesn't require a return value yourself.
You could then use those actions like this:
Given a method
private static <T> T executeAction(Action<T> action) {
return action.execute();
}
you can call it like
String result = executeAction(new Action<String>() {
@Override
public String execute() {
//code here
return "Return me!";
}
});
or, for the void action (note that you're not assigning the result to anything)
executeAction(new VoidAction() {
@Override
public void executeInternal() {
//code here
}
});
If you want to install/upgrade all packages to the latest version and you are running windows you can use this in powershell.exe
:
foreach($package in @("animations","common","compiler","core","forms","http","platform-browser","platform-browser-dynamic","router")) {
npm install @angular/$package@latest -E
}
If you also use the cli
, you can do this:
foreach($package in @('animations','common','compiler','core','forms','http','platform-browser','platform-browser-dynamic','router', 'cli','compiler-cli')){
iex "npm install @angular/$package@latest -E $(If($('cli','compiler-cli').Contains($package)){'-D'})";
}
This will save the packages exact (-E), and the cli packages in devDependencies
(-D)

I think your problem is likely related to your spring.config.location not ending the path with "/".

If spring.config.location contains directories (as opposed to files) they should end in / (and will be appended with the names generated from spring.config.name before being loaded).

The MultiByteToWideChar
answer that Charles Bailey gave is the correct one. Because LPCWSTR
is just a typedef for const WCHAR*
, widestr
in the example code there can be used wherever a LPWSTR
is expected or where a LPCWSTR
is expected.
One minor tweak would be to use std::vector<WCHAR>
instead of a manually managed array:
// using vector, buffer is deallocated when function ends
std::vector<WCHAR> widestr(bufferlen + 1);
::MultiByteToWideChar(CP_ACP, 0, instr.c_str(), instr.size(), &widestr[0], bufferlen);
// Ensure wide string is null terminated
widestr[bufferlen] = 0;
// no need to delete; handled by vector
Also, if you need to work with wide strings to start with, you can use std::wstring
instead of std::string
. If you want to work with the Windows TCHAR
type, you can use std::basic_string<TCHAR>
. Converting from std::wstring
to LPCWSTR
or from std::basic_string<TCHAR>
to LPCTSTR
is just a matter of calling c_str
. It's when you're changing between ANSI and UTF-16 characters that MultiByteToWideChar
(and its inverse WideCharToMultiByte
) comes into the picture.

If you're required to show growth as a percentage it's customary to display [NaN]
or something similar in these cases. A growth rate, on the other hand, would be reported in this case as $/month. So in your example for April
the growth rate would be calculated as ((20-0)/1
.
In any event, determining the correct method for reporting this special case is a user decision. Is it covered in your user requirements?
I recommend parsecsv-for-php to get around a number any issues with nested newlines and quotes.
Your browser is sending an HTTP GET request: Make sure you have the WebGet attribute on the operation in the contract:
[ServiceContract]
public interface IUploadService
{
[WebGet()]
[OperationContract]
string TestGetMethod(); // This method takes no arguments, returns a string. Perfect for testing quickly with a browser.
[OperationContract]
void UploadFile(UploadedFile file); // This probably involves an HTTP POST request. Not so easy for a quick browser test.
}
Many people have already explained recursion here. I would like to cite a couple of thoughts about some advantages that recursion gives from the book “Concurrency in .NET, Modern patterns of concurrent and parallel programming” by Riccardo Terrell:
“Functional recursion is the natural way to iterate in FP because it avoids mutation of state. During each iteration, a new value is passed into the loop constructor instead to be updated (mutated). In addition, a recursive function can be composed, making your program more modular, as well as introducing opportunities to exploit parallelization."
Here also are some interesting notes from the same book about tail recursion:
Tail-call recursion is a technique that converts a regular recursive function into an optimized version that can handle large inputs without any risks and side effects.
NOTE The primary reason for a tail call as an optimization is to improve data locality, memory usage, and cache usage. By doing a tail call, the callee uses the same stack space as the caller. This reduces memory pressure. It marginally improves the cache because the same memory is reused for subsequent callers and can stay in the cache, rather than evicting an older cache line to make room for a new cache line.
Edit: note that this answer is 3+ years old. For newer versions of apache, please see the answer by sp00n. Leaving this answer for users of older versions of apache.
For debugging mod_rewrite issues, you'll want to use RewriteLogLevel and RewriteLog:

There are two issues here. The first is to access fields in the array returned by your JSON parse, the second is to rename collections/fields (like sentences) away from VBA reserved names.
Let's address the second concern first. You were on the right track. First, replace all instances of sentences
with jsentences
If text within your JSON also contains the word sentences, then figure out a way to make the replacement unique, such as using "sentences":[
as the search string. You can use the VBA Replace
method to do this.
Once that's done, so VBA will stop renaming sentences to Sentences, it's just a matter of accessing the array like so:
'first, declare the variables you need:
Dim jsent as Variant
'Get arr all setup, then
For Each jsent in arr.jsentences
MsgBox(jsent.orig)
Next

rem: backup will be 2019

if none of this answers solves you the problem, I solved it by removing the tables and creating them again automatically in this way:
when creating the backup, first backup structure and be sure of add:
DROP TABLE / VIEW / PROCEDURE / FUNCTION / EVENT
CREATE PROCEDURE / FUNCTION / EVENT
IF NOT EXISTS
AUTO_INCREMENT
then just use this backup with your db and it will remove and recreate the tables you need.
Then you backup just data, and do the same, and it will work.
I suspect you're only reporting the last error in a stack like this:
ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "schema.package" has been invalidated
ORA-04065: not executed, altered or dropped package body "schema.package"
ORA-06508: PL/SQL: could not find program unit being called: "schema.package"
If so, that's because your package is stateful:
The values of the variables, constants, and cursors that a package declares (in either its specification or body) comprise its package state. If a PL/SQL package declares at least one variable, constant, or cursor, then the package is stateful; otherwise, it is stateless.
When you recompile the state is lost:
If the body of an instantiated, stateful package is recompiled (either explicitly, with the "ALTER PACKAGE Statement", or implicitly), the next invocation of a subprogram in the package causes Oracle Database to discard the existing package state and raise the exception ORA-04068.
After PL/SQL raises the exception, a reference to the package causes Oracle Database to re-instantiate the package, which re-initializes it...
You can't avoid this if your package has state. I think it's fairly rare to really need a package to be stateful though, so you should revisit anything you have declared in the package, but outside a function or procedure, to see if it's really needed at that level. Since you're on 10g though, that includes constants, not just variables and cursors.
But the last paragraph from the quoted documentation means that the next time you reference the package in the same session, you won't get the error and it will work as normal (until you recompile again).
brilliant example Jonathan Leffler, to make your code work on SLES, I needed to add an additional header to allow the pid_t object :)
#include <sys/types.h>
Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.
You can create folder using the following Java code:
File dir = new File("nameoffolder");
dir.mkdir();
By executing above you will have folder 'nameoffolder' in current folder.

This code might work for non-.NET Core MVC controllers:
this.HttpContext.Response.StatusCode = 418; // I'm a teapot
return Json(new { status = "mer" }, JsonRequestBehavior.AllowGet);
You can also use a while loop:
while (true) {
//your code
}
In the version of .NET I am using you also have to do this:
System.Net.ServicePointManager.Expect100Continue = false;
If you don't, the HttpWebRequest
class will automatically add the Expect:100-continue
request header which fouls everything up.
Also I learned the hard way that you have to have the right number of dashes. whatever you say is the "boundary" in the Content-Type
header has to be preceded by two dashes
--THEBOUNDARY
and at the end
--THEBOUNDARY--
exactly as it does in the example code. If your boundary is a lot of dashes followed by a number then this mistake won't be obvious by looking at the http request in a proxy server
chandan@cmaster:~/More$ javac New.java

for running a program.
Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

The syntax a if b else c
is a ternary operator in Python that evaluates to a
if the condition b
is true - otherwise, it evaluates to c
. It can be used in comprehension statements:
>>> [a if a else 2 for a in [0,1,0,3]]
[2, 1, 2, 3]

table = ''.join(chr(index) if index in ords_to_keep else replace_with
for index in xrange(15))
You can improve the code by asking the user when the certificate is not valid whether he wants to continue or not. Do you want to continue? As below:
ServicePointManager.ServerCertificateValidationCallback =
new RemoteCertificateValidationCallback(ValidateServerCertificate);
And add a method like this:
public static bool ValidateServerCertificate(object sender,X509Certificate certificate,X509Chain chain,SslPolicyErrors sslPolicyErrors)
{
if (sslPolicyErrors == SslPolicyErrors.None)
return true;
else
{
if (System.Windows.Forms.MessageBox.Show("The server certificate is not valid.\nAccept?", "Certificate Validation", System.Windows.Forms.MessageBoxButtons.YesNo, System.Windows.Forms.MessageBoxIcon.Question) == System.Windows.Forms.DialogResult.Yes)
return true;

I'm new with Android and the project appcompat_v7 always be created when I create new Android application project makes me so uncomfortable.
This is just a walk around. Choose Project Properties -> Android then at Library box just remove appcompat_v7_x and add appcompat_v7. Now you can delete appcompat_v7_x.
Uncheck Create Activity in create project wizard doesn't work, because when creating activity by wizard the appcompat_v7_x appear again. My ADT's version is v22.6.2-1085508.

All the previous answers are correct. Since no one have hinted out how to turn off all errors in PHP, I would like to mention it here:

This is how you save the relevant file as a Excel12 (.xlsx) file... It is not as you would intuitively think i.e. using Excel.XlFileFormat.xlExcel12

I don't know if you are still having this problem, but I had the same problem and had a different fix than what was listed in the other answer. I did install XAMPP under C:\xampp\, and my user is an admin, but there was also something else.
I had to manually go give my user full access to the C:\Users\XAMPP\ directory. By default (at least on my machine) Windows did not give my admin user rights to this new user's directory, but this is where XAMPP stores all of it's config files. Once I gave myself full access to this, everything worked perfectly.
Hope this helps!
In retrospect, I think that I must have accidentally typed in "C:\Users\XAMPP\" as the install folder during the installation process. So I think the most important thing is to make sure that the user you are actually signed into Windows as when you start XAMPP has full access to the folder that it was actually installed to.
// Before C++11
// I used following methods:
// 1.
int A[] = {10, 20, 30}; // original array A
unsigned sizeOfA = sizeof(A)/sizeof(A[0]); // calculate the number of elements
// declare vector vArrayA,
std::vector<int> vArrayA(sizeOfA); // make room for all
// array A integers
// and initialize them to 0
for(unsigned i=0; i<sizeOfA; i++)
vArrayA[i] = A[i]; // initialize vector vArrayA
//2.
int B[] = {40, 50, 60, 70}; // original array B
std::vector<int> vArrayB; // declare vector vArrayB
for (unsigned i=0; i<sizeof(B)/sizeof(B[0]); i++)
vArrayB.push_back(B[i]); // initialize vArrayB
//3.
int C[] = {1, 2, 3, 4}; // original array C
std::vector<int> vArrayC; // create an empty vector vArrayC
vArrayC.resize(sizeof(C)/sizeof(C[0])); // enlarging the number of
// contained elements
for (unsigned i=0; i<sizeof(C)/sizeof(C[0]); i++)
vArrayC.at(i) = C[i]; // initialize vArrayC
// A Note:
// Above methods will work well for complex arrays

I realize this is a very old question, but hopefully this will help someone else out as I came upon this post looking for the same thing. I had a similar issue, just that my metadata was a Guid and int. The solution is the same though. You can just make the needed metadata part of the URL.
POST accepting method in your "Controller" class:

return null;
}
Then in whatever you're registering routes, WebApiConfig.Register(HttpConfiguration config) for me in this case.
config.Routes.MapHttpRoute(
name: "FooController",
routeTemplate: "api/{controller}/{name}/{latitude}/{longitude}",
defaults: new { }
);

The actual application/ide/frontend doesn't matter much as long as it goes beyond "notepad, echo and microtime()". It's so unlikely you hire the one in a billion developer that writes perfect code all the time and his/her unit tests spotted all the errors and bottlenecks before they even occur that you want someone who can profile and/or step through the code and find errors in finite time. (That's true for probably all languages/platforms but it seems a bit of an underdeveloped skill-set amongst php developers to me, purely subjective speaking)
Replace a string :
$str = str_replace("\n", '', $str);
u using also like, (%n, %t, All Special characters, numbers, char,. etc)
which means any thing u can replace in a string.
You are having a controlled component where input
value is determined by this.state.city
. So once you submit you have to clear your state which will clear your input automatically.
onHandleSubmit(e) {
e.preventDefault();
const city = this.state.city;
this.props.onSearchTermChange(city);
this.setState({
city: ''
});
}
Very simple to fix, you just need to turn the parameter to writerow into a list.

On the one hand Long is an object, while on the other hand long is a primitive type. In order to compare them you could get the primitive type out of the Long type:
public static void main(String[] args) {
long a = 1111;
Long b = 1113;
if ((b!=null)&&
(a == b.longValue()))
{
System.out.println("Equals");
}
else
{
System.out.println("not equals");
}
}

To show a problem is NP complete, you need to:
In other words, given some information C
, you can create a polynomial time algorithm V
that will verify for every possible input X
whether X
is in your domain or not.
Prove that the problem of vertex covers (that is, for some graph G
, does it have a vertex cover set of size k
such that every edge in G
has at least one vertex in the cover set?) is in NP:
our input X
is some graph G
and some number k
(this is from the problem definition)
Take our information C
to be "any possible subset of vertices in graph G
of size k
"
Then we can write an algorithm V
that, given G
, k
and C
, will return whether that set of vertices is a vertex cover for G
or not, in polynomial time.
Then for every graph G
, if there exists some "possible subset of vertices in G
of size k
" which is a vertex cover, then G
is in NP
.
Note that we do not need to find C
in polynomial time. If we could, the problem would be in `P.
Note that algorithm V
should work for every G
, for some C
. For every input there should exist information that could help us verify whether the input is in the problem domain or not. That is, there should not be an input where the information doesn't exist.
This involves getting a known NP-complete problem like SAT, the set of boolean expressions in the form:
(A or B or C) and (D or E or F) and ...
where the expression is satisfiable, that is there exists some setting for these booleans, which makes the expression true.
Then reduce the NP-complete problem to your problem in polynomial time.
That is, given some input X
for SAT
(or whatever NP-complete problem you are using), create some input Y
for your problem, such that X
is in SAT if and only if Y
is in your problem. The function f : X -> Y
must run in polynomial time.
In the example above, the input Y
would be the graph G
and the size of the vertex cover k
.
For a full proof, you'd have to prove both:
that X
is in SAT
=> Y
in your problem
and Y
in your problem => X
in SAT
.
marcog's answer has a link with several other NP-complete problems you could reduce to your problem.
Footnote: In step 2 (Prove it is NP-hard), reducing another NP-hard (not necessarily NP-complete) problem to the current problem will do, since NP-complete problems are a subset of NP-hard problems (that are also in NP).
StringUtils is a utility class from Apache commons-lang (many libraries have it but this is the most common library). You need to download the jar and add it to your applications classpath.
You can use Collections.swap(List<?> list, int i, int j);
It's actually:
Console.WriteLine(Encoding.Default.GetString(value));
or for UTF-8 specifically:
Console.WriteLine(Encoding.UTF8.GetString(value));
unsigned mod(int a, unsigned b) {
return (a >= 0 ? a % b : b - (-a) % b);
}
I had to merge some of those good answers here! This works for me:
git remote set-url origin 'https://bitbucket.org/teamName/repo.git'
In the end, it will always prompt anyone who wants to pull from it
Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat
.
On the other hand, personally I'd suggest avoiding Calendar
and Date
entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat
is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.
Give Safe User Permission To Use Port 80
Remember, we do NOT want to run your applications as the root user, but there is a hitch: your safe user does not have permission to use the default HTTP port (80). You goal is to be able to publish a website that visitors can use by navigating to an easy to use URL like http://ip:port/
Unfortunately, unless you sign on as root, you’ll normally have to use a URL like http://ip:port
- where port number > 1024.
A lot of people get stuck here, but the solution is easy. There a few options but this is the one I like. Type the following commands:
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
Now, when you tell a Node application that you want it to run on port 80, it will not complain.

Remember that stringToEdit.replaceAll(String, String)
returns the result string. It doesn't modify stringToEdit because Strings are immutable in Java. To get any change to stick, you should use
stringToEdit = stringToEdit.replaceAll("'", "\\'");

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:
SELECT
p1.kArtikel,
p1.cName,
p1.cKurzBeschreibung,
p1.dLetzteAktualisierung,
p1.dErstellt,
p1.cSeo,
p2.kartikelpict,
p2.nNr,
p2.cPfad
FROM
tartikel AS p1 INNER JOIN tartikelpict AS p2
ON p1.kArtikel = p2.kArtikel
WHERE
DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
AND p2.nNr = 1
ORDER BY
p1.kArtikel DESC
LIMIT

FRP is a combination of Functional programming(programming paradigm built upon the idea of everything is a function) and reactive programming paradigm (built upon the idea that everything is a stream(observer and observable philosophy)). It is supposed to be the best of the worlds.
Check out Andre Staltz post on reactive programming to start with.
An Int
(or TinyInt
) aligned to an Enum
field would be my methodology.
First, if you have a single bit
field in a database, the row will still use a full byte, so as far as space savings, it only pays off if you have multiple bit
fields.
Second, strings/chars have a "magic value" feel to them, regardless of how obvious they may seem at design time. Not to mention, it lets people store just about any value they would not necessarily map to anything obvious.
Third, a numeric value is much easier (and better practice) to create a lookup table for, in order to enforce referential integrity, and can correlate 1-to-1 with an enum, so there is parity in storing the value in memory within the application or in the database.

Android’s new In-App Review system launched which lets developers ask for Play store reviews without leaving the app.
To check design guidelines and when to display a review card, refer to the official document
To implement:
implementation 'com.google.android.play:core:1.8.0'
Create a ReviewManager instance and request ReviewInfo object. The ReviewInfo object to be pre-cached and then can trigger "launchReviewFlow" to present the Review card to the user.
private var reviewInfo: ReviewInfo? = null
val manager = ReviewManagerFactory.create(context)
val request = manager.requestReviewFlow()
requestFlow.addOnCompleteListener { request ->
if (request.isSuccessful) {
//Received ReviewInfo object
reviewInfo = request.result
} else {
//Problem in receiving object
reviewInfo = null
}
reviewInfo?.let {
val flow = reviewManager.launchReviewFlow(this@MainActivity, it)
flow.addOnCompleteListener {
//Irrespective of the result, the app flow should continue
}
}
Note : It is suggested to show the review flow after the user has experienced enough of your app or game.
When to request an in-app review:
Few points before testing this:
While testing new functionalities, mostly we create a new project that would have new ApplicationId, make sure you give an ApplicationId that is already released and available in the play store.
If you have given feedback in the past for your app, in-app review API’s launchReviewFlow will not present any Review card. It simply triggers a success event.
Due to quota limitations, calling a launchReviewFlow method might not always display a dialog. It should not be linked with any click event.
I am using the springframework android artifact as an example
open build.gradle
Then add the following at the same level as apply plugin: 'android'
apply plugin: 'android'
repositories {
mavenCentral()
}
dependencies {
compile group: 'org.springframework.android', name: 'spring-android-rest-template', version: '1.0.1.RELEASE'
}
you can also use this notation for maven artifacts
compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
Your IDE should show the jar and its dependencies under 'External Libraries' if it doesn't show up try to restart the IDE (this happened to me quite a bit)
here is the example that you provided that works
buildscript {
repositories {
maven {
url 'repo1.maven.org/maven2';
}
}
dependencies {
classpath 'com.android.tools.build:gradle:0.4'
}
}
apply plugin: 'android'
repositories {
mavenCentral()
}
dependencies {
compile files('libs/android-support-v4.jar')
compile group:'com.squareup.picasso', name:'picasso', version:'1.0.1'
}
android {
compileSdkVersion 17
buildToolsVersion "17.0.0"
defaultConfig {
minSdkVersion 14
targetSdkVersion 17
}
}
You could use the GetSize function to get those information, cv.GetSize(im) would return a tuple with the width and height of the image. You can also use im.depth and img.nChan to get some more information.
And to resize an image, I would use a slightly different process, with another image instead of a matrix. It is better to try to work with the same type of data:
size = cv.GetSize(im)
thumbnail = cv.CreateImage( ( size[0] / 10, size[1] / 10), im.depth, im.nChannels)
cv.Resize(im, thumbnail)
Hope this helps ;)

I just want to add what worked for me, I added height and width to both divs and used bootstrap to make it responsive
<div class="col-lg-1 mapContainer">
<div id="map"></div>
</div>
#map{
height: 100%;
width:100%;
}
.mapContainer{
height:200px;
width:100%
}
in order for col-lg-1
to work add bootstrap reference located

I encountered this problem today as well. I am using Windows and the system language by default is Chinese. Hence, someone may encounter this Unicode error similarly. Simply add encoding = 'utf-8'
:
with open("test.html", "r", encoding='utf-8') as f:
text= f.read()
Readonly will allow the user to copy text from it. Disabled will not.
As the documentation states (link), you can use the channel resource type and operation List to get all the videos in an channel. This operation must be performed using argument 'channel id'.
For a ridiculously large and probably redundant version, try a lot of for loops.
string stringlist[10];
int count = 0;
for (int i = 0; i < sequence.length(); i++)
{
if (sequence[i] == ' ')
{
stringlist[count] = sequence.substr(0, i);
sequence.erase(0, i+1);
i = 0;
count++;
}
else if (i == sequence.length()-1) // Last word
{
stringlist[count] = sequence.substr(0, i+1);
}
}
It isn't pretty, but by and large (Barring punctuation and a slew of other bugs) it works!
replace:
input, select, textarea{
color: #000;
}
with:
input, select, textarea{
color: #f00;
}
or color: #ff0000;
personally i use underscore for this kind of stuff... so
a = _.find(results,function(rw){ return rw.id == 2 });
then "a" would be the row that you wanted of your array where the id was equal to 2
Simple variant:
Regex.Replace(input, @"\r\n|\r|\n", "\r\n")
For better performance:
static Regex newline_pattern = new Regex(@"\r\n|\r|\n", RegexOptions.Compiled);
[...]
newline_pattern.Replace(input, "\r\n");
Use position:fixed
on the video, set it to 100% width/height, and put a negative z-index
on it so it appears behind everything.
If you look at VideoJS, the controls are just html elements sitting on top of the video, using z-index to make sure they're above.
HTML
<video id="video_background" src="video.mp4" autoplay>
(Add webm and ogg sources to support more browsers)
CSS
#video_background {
position: fixed;
top: 0;
left: 0;
bottom: 0;
right: 0;
z-index: -1000;
}
It'll work in most HTML5 browsers, but probably not iPhone/iPad, where the video needs to be activated, and doesn't like elements over it.
Close, you can use
$('#select_2 option:selected').html()
There's already a lot about how to not leak, but if you need a tool to help you track leaks take a look at:
// Month here is 1-indexed (January is 1, February is 2, etc). This is
// because we're using 0 as the day so that it returns the last day
// of the last month, so you have to add 1 to the month number
// so it returns the correct amount of days
function daysInMonth (month, year) {
return new Date(year, month, 0).getDate();
}
// July
daysInMonth(7,2009); // 31
// February
daysInMonth(2,2009); // 28
daysInMonth(2,2008); // 29
Run the hist() function without making a graph, log-transform the counts, and then draw the figure.
hist.data = hist(my.data, plot=F)
hist.data$counts = log(hist.data$counts, 2)
plot(hist.data)
It should look just like the regular histogram, but the y-axis will be log2 Frequency.
You can use jquery
HTML file
<input id="email" name="email">
jquery code
$('#email').bind('copy paste', function (e) {
e.preventDefault();
});
Question is little old. As this question is very noisy so posting what I did solved with static method as a util. Just copy, paste and use it!
public static String getFormattedDate(Date date){
Calendar cal=Calendar.getInstance();
cal.setTime(date);
//2nd of march 2015
int day=cal.get(Calendar.DATE);
if(!((day>10) && (day<19)))
switch (day % 10) {
case 1:
return new SimpleDateFormat("d'st' 'of' MMMM yyyy").format(date);
case 2:
return new SimpleDateFormat("d'nd' 'of' MMMM yyyy").format(date);
case 3:
return new SimpleDateFormat("d'rd' 'of' MMMM yyyy").format(date);
default:
return new SimpleDateFormat("d'th' 'of' MMMM yyyy").format(date);
}
return new SimpleDateFormat("d'th' 'of' MMMM yyyy").format(date);
}
For testing purose
Example: calling it from main method!
Date date = new Date();
Calendar cal=Calendar.getInstance();
cal.setTime(date);
for(int i=0;i<32;i++){
System.out.println(getFormattedDate(cal.getTime()));
cal.set(Calendar.DATE,(cal.getTime().getDate()+1));
}

Your question has already been answered, but IIRC you can replace lines like:
if d.has_key(scope_item):
with:
if scope_item in d:
That is, d
references d.keys()
in that construction. Sometimes defaultdict
isn't the best option (for example, if you want to execute multiple lines of code after the else
associated with the above if
), and I find the in
syntax easier to read.
Here's what I'm using to deal with a similar problem I encountered while trying to access MailChimp's API. This does the same thing, just formatted nicer.
import urllib2
import base64
chimpConfig = {
"headers" : {
"Content-Type": "application/json",
"Authorization": "Basic " + base64.encodestring("hayden:MYSECRETAPIKEY").replace('\n', '')
},
"url": 'https://us12.api.mailchimp.com/3.0/'}
#perform authentication
datas = None
request = urllib2.Request(chimpConfig["url"], datas, chimpConfig["headers"])
result = urllib2.urlopen(request)
I use this (good on Debian 8):
alias psj='ps --no-headers -ww -C java -o pid,user,start_time,command'
Just turn the LINQ to Entity query into a LINQ to Objects query (e.g. call ToArray) anytime you need to use a method call in your LINQ query.
button1, button2 and button3 have same even handler
private void button1_Click(Object sender, EventArgs e)
{
Button btnSender = (Button)sender;
if (btnSender == button1 || btnSender == button2)
{
//some code here
}
else if (btnSender == button3)
//some code here
}
According to official documentation https://keras.io/getting-started/faq/#how-can-i-install-hdf5-or-h5py-to-save-my-models-in-keras
you can do :
first test if you have h5py installed by running the
import h5py
if you dont have errors while importing h5py you are good to save:
from keras.models import load_model
model.save('my_model.h5') # creates a HDF5 file 'my_model.h5'
del model # deletes the existing model
# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')
If you need to install h5py http://docs.h5py.org/en/latest/build.html
When you do -
for word in string:
You are not iterating through the words in the string, you are iterating through the characters in the string. To iterate through the words, you would first need to split the string into words , using str.split()
, and then iterate through that . Example -
my_string = "this is a string"
for word in my_string.split():
print (word)
Please note, str.split()
, without passing any arguments splits by all whitespaces (space, multiple spaces, tab, newlines, etc).
You can use Array.findIndex
.
var data= [{
"name": "placeHolder",
"section": "right"
}, {
"name": "Overview",
"section": "left"
}, {
"name": "ByFunction",
"section": "left"
}, {
"name": "Time",
"section": "left"
}, {
"name": "allFit",
"section": "left"
}, {
"name": "allbMatches",
"section": "left"
}, {
"name": "allOffers",
"section": "left"
}, {
"name": "allInterests",
"section": "left"
}, {
"name": "allResponses",
"section": "left"
}, {
"name": "divChanged",
"section": "right"
}];
var index = data.findIndex(obj => obj.name=="allInterests");
console.log(index);

The OP's solution is nearly there, there are just a few things to make it more Pythonic.
For one, there's no need to get the length of the list. Empty lists in Python evaluate to False in an if check. Just simply say
if list:
Additionally, it's a very Bad Idea to assign to variables that overlap with reserved words. "list" is a reserved word in Python.
So let's change that to
some_list = get_list()
if some_list:
A really important point that a lot of solutions here miss is that all Python functions/methods return None by default. Try the following below.
def does_nothing():
pass
foo = does_nothing()
print foo
Unless you need to return None to terminate a function early, it's unnecessary to explicitly return None. Quite succinctly, just return the first entry, should it exist.
some_list = get_list()
if some_list:
return list[0]
And finally, perhaps this was implied, but just to be explicit (because explicit is better than implicit), you should not have your function get the list from another function; just pass it in as a parameter. So, the final result would be
def get_first_item(some_list):
if some_list:
return list[0]
my_list = get_list()
first_item = get_first_item(my_list)
As I said, the OP was nearly there, and just a few touches give it the Python flavor you're looking for.
Try this SQL statement:
update Table set Column =( Column - your val )
Just a slight expansion on the 'angular' solution. I wanted to exclude an item based on it's numeric id, so the ! approach doesn't work. The more general solution which should work for { name: 'ted' } or { id: 42 } is:
mycollection = $filter('filter')(myCollection, { id: theId }, function (obj, test) {
return obj !== test; });
Another way to do is is to use file_get_contents() and have a template HTML page
TEMPLATE PAGE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head><title>$title</title></head>

PHP Function
function YOURFUNCTIONNAME($url){
$html_string = file_get_contents($url);
return $html_string;
}
