You have a CryptoListPresenter _presenter
but you are never initializing it. You should either be doing that when you declare it or in your initState()
(or another appropriate but called-before-you-need-it method).
One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.
EDIT:
I see diegoveloper beat me to answering this, and that the OP asked a follow up.
@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);
, or
CryptoListPresenter _presenter;
@override
void initState() {
_presenter = new CryptoListPresenter(...);
}
For me, it had nothing to do with the code that I was using. For Azure we had to go into the settings of the App Service, on the side menu the entry "CORS". There I had to add the domain that I was requesting stuff from. Once I had that in, everything was magic.
I found my solution after hours of research here.
Stop MySQL
sudo service mysql stop
Make MySQL service directory.
sudo mkdir /var/run/mysqld
Give MySQL user permission to write to the service directory.
sudo chown mysql: /var/run/mysqld
Start MySQL manually, without permission checks or networking.
sudo mysqld_safe --skip-grant-tables --skip-networking &
Log in without a password.
mysql -uroot mysql
update password
UPDATE mysql.user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE User='root' AND Host='%';
EXIT;
Turn off MySQL.
sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown
Start the MySQL service normally.
sudo service mysql start
I have a lib what use https://requests.readthedocs.io/en/master/ what use https://pypi.org/project/certifi/ but I have a custom CA included in my /etc/ssl/certs
.
So I solved my problem like this:
# Your TLS certificates directory (Debian like)
export SSL_CERT_DIR=/etc/ssl/certs
# CA bundle PATH (Debian like again)
export CA_BUNDLE_PATH="${SSL_CERT_DIR}/ca-certificates.crt"
# If you have a virtualenv:
. ./.venv/bin/activate
# Get the current certifi CA bundle
CERTFI_PATH=`python -c 'import certifi; print(certifi.where())'`
test -L $CERTFI_PATH || rm $CERTFI_PATH
test -L $CERTFI_PATH || ln -s $CA_BUNDLE_PATH $CERTFI_PATH
Et voilà !
Solution for me is: I clean both the solution and the project. And just rebuild the project. This error happens because I tried to delete the main file (only keep library files) in the previous build so at the current build the old stuff is still kept in the built directory. That's why unresolved things happened. "unresolved external symbol _main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ) "
view = MyCustomView(frame: CGRectZero)
In this line you are trying to set empty rect for your custom view. That's why you cant see your view in simulator.
I solved changing
readable_json['firstName']
by
readable_json[0]['firstName']
In my case: spring boot 2 ,multiple datasource(default and custom). entityManager.createQuery
go wrong: 'entity is not mapped'
while debug, i find out that the entityManager's unitName is wrong(should be custom,but the fact is default) the right way:
@PersistenceContext(unitName = "customer1") // !important,
private EntityManager em;
the customer1
is from the second datasource config class:
@Bean(name = "customer1EntityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
@Qualifier("customer1DataSource") DataSource dataSource) {
return builder.dataSource(dataSource).packages("com.xxx.customer1Datasource.model")
.persistenceUnit("customer1")
// PersistenceUnit injects an EntityManagerFactory, and PersistenceContext
// injects an EntityManager.
// It's generally better to use PersistenceContext unless you really need to
// manage the EntityManager lifecycle manually.
// ?4?
.properties(jpaProperties.getHibernateProperties(new HibernateSettings())).build();
}
Then,the entityManager is right.
But, em.persist(entity) doesn't work,and the transaction doesn't work.
Another important point is:
@Transactional("customer1TransactionManager") // !important
public Trade findNewestByJdpModified() {
//test persist,working right!
Trade t = new Trade();
em.persist(t);
log.info("t.id" + t.getSysTradeId());
//test transactional, working right!
int a = 3/0;
}
customer1TransactionManager
is from the second datasource config class:
@Bean(name = "customer1TransactionManager")
public PlatformTransactionManager transactionManager(
@Qualifier("customer1EntityManagerFactory") EntityManagerFactory entityManagerFactory) {
return new JpaTransactionManager(entityManagerFactory);
}
The whole second datasource config class is :

The preprocessor is looking for StdCUtil/split.h
in
./
(i.e. /root/Core/
, the directory that contains the #include statement). So ./
+ StdCUtil/split.h
= ./StdCUtil/split.h
and the file is missingand in
$INC_DIR
(i.e. ../StdCUtil/
= /root/Core/../StdCUtil/
= /root/StdCUtil/
). So ../StdCUtil/
+ StdCUtil/split.h
= ../StdCUtil/StdCUtil/split.h
and the file is missingYou can fix the error changing the $INC_DIR
variable (best solution):
$INC_DIR = ../
or the include directive:
#include "split.h"
but in this way you lost the "path syntax" that makes it very clear what namespace or module the header file belongs to.
Reference:
EDIT/UPDATE
It should also be
CXX = g++
CXXFLAGS = -c -Wall -I$(INC_DIR)
...
%.o: %.cpp $(DEPS)
$(CXX) -o $@ $< $(CXXFLAGS)

LocalDate.parse( "2013-09-18" )

The Question and other Answers are out-of-date. The troublesome old legacy date-time classes are now supplanted by the java.time classes.
Your input string happens to comply with standard ISO 8601 format, YYYY-MM-DD. The java.time classes use ISO 8601 formats by default when parsing and generating string representations of date-time values. So no need to specify a formatting pattern.
LocalDate
The LocalDate
class represents a date-only value without time-of-day and without time zone.
LocalDate ld = LocalDate.parse( "2013-09-18" );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
var result = from cx in CustomerList
group cx by cx.GroupID into cxGroup
orderby cxGroup.Key
select cxGroup;
foreach (var cxGroup in result) {
Console.WriteLine(String.Format("GroupID = {0}", cxGroup.Key));
foreach (var cx in cxGroup) {
Console.WriteLine(String.Format("\tUserID = {0}, UserName = {1}, GroupID = {2}",
new object[] { cx.ID, cx.Name, cx.GroupID }));
}
}
you can get method parameter and its value and if annotated with a annotation with following code:
Map<String, Object> annotatedParameterValue = getAnnotatedParameterValue(MethodSignature.class.cast(jp.getSignature()).getMethod(), jp.getArgs());
....
private Map<String, Object> getAnnotatedParameterValue(Method method, Object[] args) {
Map<String, Object> annotatedParameters = new HashMap<>();
Annotation[][] parameterAnnotations = method.getParameterAnnotations();
Parameter[] parameters = method.getParameters();
int i = 0;
for (Annotation[] annotations : parameterAnnotations) {
Object arg = args[i];
String name = parameters[i++].getDeclaringExecutable().getName();
for (Annotation annotation : annotations) {
if (annotation instanceof AuditExpose) {
annotatedParameters.put(name, arg);
}
}
}
return annotatedParameters;
}
I'm going to answer my own question.
Therefore, the following works for me
$qb->select('c')
->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
->where('c.username = :username');
or
$qb->select('c')
->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
->where('c.username = :username');
GRV.DataSource = Class1.DataTable;
GRV.DataBind();
Class1.GRV.Rows[e.RowIndex].Delete();
GRV.DataSource = Class1.DataTable;
GRV.DataBind();
You need to qualify the a
part of the selector too:
.button input, .button a {
//css stuff here
}
Basically, when you use the comma to create a group of selectors, each individual selector is completely independent. There is no relationship between them.
Your original selector therefore matched "all elements of type 'input' that are descendants of an element with the class name 'button', and all elements of type 'a'".
Just in case this is helpful to others, here's my anecdote:
I found this thread as a result of a problem I encountered while I was using Postman to send test data to my RESTEasy server, where- after a significant code change- I was getting nothing but 415 Unsupported Media Type errors.
Long story short, I tore everything out, eventually I tried to run the trivial file upload example I knew worked; it didn't. That's when I realized that the problem was with my Postman request. I normally don't send any special headers, but in a previous test I had added a "Content-Type": "application/json" header. OF COURSE, I was trying to upload "multipart/form-data." Removing it solved my issue.
Moral: Check your headers before you blow up your world. ;)
I'm not really sure if that was the situation with Roundcube version from May '12, but for current one the answer is that you can't delete roundcube_sessauth
cookie from JavaScript, as it is marked as HttpOnly
. And this means it's not accessible from JS client side code and can be removed only by server side script or by direct user action (via some browser mechanics like integrated debugger or some plugin).
The structure of your menu code is the issue:
cin >> choice; // new line character is left in the stream
switch ( ... ) {
// We enter the handlers, '\n' still in the stream
}
cin.ignore(); // Put this right after cin >> choice, before you go on
// getting input with getline.
The m000493
method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd
:
string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));
string result = m000493(p0, "_p0lizei.");
// result == "gaia^unplugged^Ta..."
with return m0001cd(builder3.ToString());
changed to return builder3.ToString();
.
In your theme's functions.php
:
function my_custom_js() {
echo '<script type="text/javascript" src="myscript.js"></script>';
}
// Add hook for admin <head></head>
add_action( 'admin_head', 'my_custom_js' );
// Add hook for front-end <head></head>
add_action( 'wp_head', 'my_custom_js' );
SQL Server 2012 above, I prefer use format() function, more simplify.
SELECT format(date,'MM.yyyy') AS Mjesec, SUM(marketingExpense) AS SumaMarketing, SUM(revenue) AS SumaZarada
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY format(date,'MM.yyyy')
That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

Your group statement will group by group ID. For example, if you then write:
foreach (var group in groupedCustomerList)
{
Console.WriteLine("Group {0}", group.Key);
foreach (var user in group)
{
Console.WriteLine(" {0}", user.UserName);
}
}
that should work fine. Each group has a key, but also contains an IGrouping<TKey, TElement>
which is a collection that allows you to iterate over the members of the group. As Lee mentions, you can convert each group to a list if you really want to, but if you're just going to iterate over them as per the code above, there's no real benefit in doing so.
I create a library RMMapper (https://github.com/roomorama/RMMapper) to help save custom object into NSUserDefaults easier and more convenient, because implementing encodeWithCoder and initWithCoder is super boring!
To mark a class as archivable, just use: #import "NSObject+RMArchivable.h"
To save a custom object into NSUserDefaults:
#import "NSUserDefaults+RMSaveCustomObject.h"
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
[defaults rm_setCustomObject:user forKey:@"SAVED_DATA"];
To get custom obj from NSUserDefaults:
user = [defaults rm_customObjectForKey:@"SAVED_DATA"];
Others have pointed out the error in your existing code, but I'd like to take two steps further. Firstly, assuming you're using Java 1.5+, you can achieve greater readability using the enhanced for loop:
Customer findCustomerByid(int id){
for (Customer customer : customers) {
if (customer.getId() == id) {
return customer;
}
}
return null;
}
This has also removed the micro-optimisation of returning null
before looping - I doubt that you'll get any benefit from it, and it's more code. Likewise I've removed the exists
flag: returning as soon as you know the answer makes the code simpler.
Note that in your original code I think you had a bug. Having found that the customer at index i
had the right ID, you then returned the customer at index id
- I doubt that this is really what you intended.
Secondly, if you're going to do a lot of lookups by ID, have you considered putting your customers into a Map<Integer, Customer>
?
If you are using SQL Server 2012+ you can use CONCAT function in which we don't have to do any explicit conversion
SET @ActualWeightDIMS = Concat(@Actual_Dims_Lenght, 'x', @Actual_Dims_Width, 'x'
, @Actual_Dims_Height)
tomcat is designed as JSP servlet container. Apache is designed PHP web server. Use apache as web server, responding for PHP request, and direct JSP servlet request to tomcat container. should be better implementation.
This is probably unlikely, but given that your observed behaviour is unusual it needs to be checked and no-one else has mentioned it.
Are you absolutely sure that all objects are owned by dbo and you don't have a rogue copies owned by yourself or a different user present as well?
Just occasionally when I've seen odd behaviour it's because there was actually two copies of an object and which one you get depends on what is specified and who you are logged on as. For example it is perfectly possible to have two copies of a view or procedure with the same name but owned by different owners - a situation that can arise where you are not logged onto the database as a dbo and forget to specify dbo as object owner when you create the object.
In note that in the text you are running some things without specifying owner, eg
sp_recompile ViewOpener
if for example there where two copies of viewOpener present owned by dbo and [some other user] then which one you actually recompile if you don't specify is dependent upon circumstances. Ditto with the Report_Opener view - if there where two copies (and they could differ in specification or execution plan) then what is used depends upon circumstances - and as you do not specify owner it is perfectly possible that your adhoc query might use one and the compiled procedure might use use the other.
As I say, it's probably unlikely but it is possible and should be checked because your issues could be that you're simply looking for the bug in the wrong place.
Sorry if I've missed the point, but wouldn't the following do what you want on it's own?
SELECT distinct idCustomer FROM reservations
WHERE DATEPART(hour, insertDate) >= 2
If you want to do some high-powered debugging, you can subscribe to every change of the state and pause the app to see what's going on in detail as follows.
store.jsstore.subscribe( () => {
console.log('state\n', store.getState());
debugger;
});
Place that in the file where you do createStore
.
To copy the state
object from the console to the clipboard, follow these steps:
Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.
Chrome also has a copy()
method, so copy(temp1)
in the console should copy that object to your clipboard.
https://stackoverflow.com/a/25140576
https://scottwhittaker.net/chrome-devtools/2016/02/29/chrome-devtools-copy-object.html
You can view the object in a json viewer like this one: http://jsonviewer.stack.hu/
You can compare two json objects here: http://www.jsondiff.com/
The first method is right.
The second method kills kittens if you attempt to do anything with x
after the fact other than Object
methods.
This is the simplest way to do it.
let total = parseInt(('100,000.00'.replace(',',''))) + parseInt(('500,000.00'.replace(',','')))
Without defaultdict
, you can probably assign new values to unseen keys but you cannot modify it. For example:
import collections
d = collections.defaultdict(int)
for i in range(10):
d[i] += i
print(d)
# Output: defaultdict(<class 'int'>, {0: 0, 1: 1, 2: 2, 3: 3, 4: 4, 5: 5, 6: 6, 7: 7, 8: 8, 9: 9})
import collections
d = {}
for i in range(10):
d[i] += i
print(d)
# Output: Traceback (most recent call last): File "python", line 4, in <module> KeyError: 0
To add a new remote, use the git remote add
command on the terminal, in the directory your repository is stored at.
The git remote set-url
command changes an existing remote repository URL.
So basicly, remote add
is to add a new one, remote set-url
is to update an existing one
Use the modulus (%

If you want to have Node.js style require
you can use something like this:
var require = (function () {
var cache = {};
function loadScript(url) {
var xhr = new XMLHttpRequest(),
fnBody;
xhr.open('get', url, false);
xhr.send();
if (xhr.status === 200 && xhr.getResponseHeader('Content-Type') === 'application/x-javascript') {
fnBody = 'var exports = {};\n' + xhr.responseText + '\nreturn exports;';
cache[url] = (new Function(fnBody)).call({});
}
}
function resolve(module) {
//TODO resolve urls
return module;
}
function require(module) {
var url = resolve(module);
if (!Object.prototype.hasOwnProperty.call(cache, url)) {
loadScript(url);
}
return cache[url];
}
require.cache = cache;
require.resolve = resolve;
return require;
}());
Beware: this code works but is incomplete (especially url resolving) and does not implement all Node.js features (I just put this together last night). YOU SHOULD NOT USE THIS CODE in real apps but it gives you a starting point. I tested it with this simple module and it works:
function hello() {
console.log('Hello world!');
}
exports.hello = hello;
Check whether your phone supports the video format or not.Even I had the problem when playing a 3gp file but it played a mp4 file perfectly.
By postfixing the URL with ?WSDL
If the URL is for example:
http://webservice.example:1234/foo
You use:
http://webservice.example:1234/foo?WSDL
And the wsdl will be delivered.
I found a good way to do this with using a function and basic code. This is a code that accepts a string and counts the number of capital letters, lowercase letters and also 'other'. Other is classed as a space, punctuation mark or even Japanese and Chinese characters.
def check(count):
lowercase = 0
uppercase = 0
other = 0
low = 'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'
upper = 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'
for n in count:
if n in low:
lowercase += 1
elif n in upper:
uppercase += 1
else:
other += 1
print("There are " + str(lowercase) + " lowercase letters.")
print("There are " + str(uppercase) + " uppercase letters.")
print("There are " + str(other) + " other elements to this sentence.")
To browse .NET code dependencies, you can use the capabilities of the tool NDepend. The tool proposes:
For example such query can look like:
from m in Methods
let depth = m.DepthOfIsUsing("NHibernate.NHibernateUtil.Entity(Type)")
where depth >= 0 && m.IsUsing("System.IDisposable")
orderby depth
select new { m, depth }
And its result looks like: (notice the code metric depth, 1 is for direct callers, 2 for callers of direct callers...) (notice also the Export to Graph button to export the query result to a Call Graph)
The dependency graph looks like:
The dependency matrix looks like:
The dependency matrix is de-facto less intuitive than the graph, but it is more suited to browse complex sections of code like:

I'm trying for the simplest and most self-explanatory method here:
git status | grep "On branch" | cut -c 11-
It means there is an extension=...
or zend_extension=...
line in one of your php configuration files (php.ini, or another close to it) that is trying to load that extension : ixed.5.2.lin
Unfortunately that file or path doesn't exist or the permissions are incorrect.
.ini
files that are loaded by PHP (phpinfo()
can indicate which ones are) - one of them should try to load that extension.theller's solution for wget is really useful, however, i found it does not print out the progress throughout the downloading process. It's perfect if you add one line after the print statement in reporthook.
import sys, urllib
def reporthook(a, b, c):
print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
sys.stdout.flush()
for url in sys.argv[1:]:
i = url.rfind("/")
file = url[i+1:]
print url, "->", file
urllib.urlretrieve(url, file, reporthook)
print
The WebClient class should be more than capable of handling the functionality you describe, for example:
System.Net.WebClient wc = new System.Net.WebClient();
byte[] raw = wc.DownloadData("http://www.yoursite.com/resource/file.htm");
string webData = System.Text.Encoding.UTF8.GetString(raw);
or (further to suggestion from Fredrick in comments)
System.Net.WebClient wc = new System.Net.WebClient();
string webData = wc.DownloadString("http://www.yoursite.com/resource/file.htm");
When you say it took 30 seconds, can you expand on that a little more? There are many reasons as to why that could have happened. Slow servers, internet connections, dodgy implementation etc etc.
You could go a level lower and implement something like this:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.yoursite.com/resource/file.htm");

However, at the end of the day the WebClient class wraps up this functionality for you. So I would suggest that you use WebClient and investigate the causes of the 30 second delay.
I was getting a consistent 15 second delay on the first request after 4 minutes of inactivity. My problem was that my app was using Windows Integrated Authentication to SQL Server and the service profile was in a different domain than the server. This caused a cross-domain authentication from IIS to SQL upon app initialization - and this was the real source of my delay. I changed to using a SQL login instead of windows authentication. The delay was immediately gone. I still have all the app initialization settings in place to help improve performance but they may have not been needed at all in my case.

You can check the framework on which system was created and developed, and then changes the framework of your current solution to the old framework. You can do this by right click on the solution and then choose properties. In Application section you can change the framework.
To declare a function that takes a pointer to an int:
void Foo(int *x);
To use this function:
int x = 4;
int *x_ptr = &x;
Foo(x_ptr);
Foo(&x);
If you want a pointer for another type of object, it's much the same:
void Foo(Object *o);
But, you may prefer to use references. They are somewhat less confusing than pointers:
// pass a reference
void Foo(int &x)
{
x = 2;
}
//pass a pointer
void Foo_p(int *p)
{
*x = 9;
}
// pass by value
void Bar(int x)
{
x = 7;
}
int x = 4;
Foo(x); // x now equals 2.
Foo_p(&x); // x now equals 9.
Bar(x); // x still equals 9.
With references, you still get to change the x that was passed to the function (as you would with a pointer), but you don't have to worry about dereferencing or address of operations.
As recommended by others, check out the C++FAQLite. It's an excellent resource for this.
Edit 3 response:
bar = &foo means: Make bar point to foo in memory
Yes.
*bar = foo means Change the value that bar points to to equal whatever foo equals
Yes.
If I have a second pointer (int *oof), then:
bar = oof means: bar points to the oof pointer
bar will point to whatever oof points to. They will both point to the same thing.
bar = *oof means: bar points to the value that oof points to, but not to the oof pointer itself
No. You can't do this (assuming bar is of type int *) You can make pointer pointers. (int **), but let's not get into that... You cannot assign a pointer to an int (well, you can, but that's a detail that isn't in line with the discussion).
*bar = *oof means: change the value that bar points to to the value that oof points to
Yes.
&bar = &oof means: change the memory address that bar points to be the same as the memory address that oof points to
No. You can't do this because the address of operator returns an rvalue. Basically, that means you can't assign something to it.
NOTE: HSSFDateUtil is deprecated
If you know which cell i.e. column position say 0 in each row is going to be a date, you can go for
row.getCell(0).getDateCellValue()
directly.
http://poi.apache.org/apidocs/org/apache/poi/hssf/usermodel/HSSFCell.html#getDateCellValue()
UPDATE: Here is an example - you can apply this in your switch case code above. I am checking and printing the Numeric as well as Date value. In this case the first column in my sheet has dates, hence I use row.getCell(0).
You can use the if (HSSFDateUtil.isCellDateFormatted ..
code block directly in your switch case.
if (row.getCell(0).getCellType() == HSSFCell.CELL_TYPE_NUMERIC)
System.out.println ("Row No.: " + row.getRowNum ()+ " " +
row.getCell(0).getNumericCellValue());
if (HSSFDateUtil.isCellDateFormatted(row.getCell(0))) {
System.out.println ("Row No.: " + row.getRowNum ()+ " " +
row.getCell(0).getDateCellValue());
}
}
The output is
Row No.: 0 39281.0
Row No.: 0 Wed Jul 18 00:00:00 IST 2007
Row No.: 1 39491.0
Row No.: 1 Wed Feb 13 00:00:00 IST 2008
Row No.: 2 39311.0

To build uri with get parameters, Uri.Builder provides a more effective way.
Uri uri = new Uri.Builder()
.scheme("http")
.authority("foo.com")
.path("someservlet")
.appendQueryParameter("param1", foo)
.appendQueryParameter("param2", bar)
.build();
The steps are very simple and it'll take just few mins. 1.Go to your C drive and in that go to the 'USER' section. 2.Under 'USER' section go to your 'name(e.g-'user1') and then find ".eclipse" folder and delete that folder 3.Along with that folder also delete "eclipse" folder and you can find that you're work has been done completely.
by making date picker input disabled achieve this but if you want to submit form data then its a problem.
so after lot of juggling this seems to me a perfect solution
1.make your HTML input readonly on some condition.
<input class="form-control date-picker" size="16" data-date-format="dd/mm/yyyy"
th:autocomplete="off"
th:name="birthDate" th:id="birthDate"
type="text" placeholder="dd/mm/jjjj"
th:value="*{#dates.format(birthDate,'dd/MM/yyyy')}"
th:readonly="${client?.isDisableForAoicStatus()}"/>
2. in your js in ready function check for readonly attribute.
$(document).ready(function (e) {
if( $(".date-picker").attr('readonly') == 'readonly') {
$("#birthDate").removeClass('date-picker');
}
});
this will stop the calendar pop up invoking when you click on the readonly field.also this will not make any problem in submit data. But if you make the field disable this will not allow you to submit value.
The input date value format needs the date specified as per http://tools.ietf.org/html/rfc3339#section-5.6 full-date.
So I've ended up doing:
<input type="date" id="last-start-date" value="@string.Format("{0:yyyy-MM-dd}", Model.LastStartDate)" />
I did try doing it "properly" using:
[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
public DateTime LastStartDate
{
get { return lastStartDate; }
set { lastStartDate = value; }
}
with
@Html.TextBoxFor(model => model.LastStartDate,
new { type = "date" })
Unfortunately that always seemed to set the value attribute of the input to a standard date time so I've ended up applying the formatting directly as above.
Edit:
According to Jorn if you use
@Html.EditorFor(model => model.LastStartDate)
instead of TextBoxFor it all works fine.

I know this question wanted inline block, but try to view http://jsfiddle.net/N9mzE/1/ in IE 7 (the oldest browser supported where I work). The divs are not side by side.
OP said he did not want to use floats because he did not like them. Well...in my opinion, making good webpages that does not look weird in any browsers should be the maingoal, and you do this by using floats.
Honestly, I can see the problem. Floats are fantastic.
My ajax never gets fired until I wrapped the whole thing in

I typedef my structs, but use the same name for both the tag and the typedef. The tag is not meant to be commonly used. Instead it's preferrable to use the typedef. I also forward declare the typedef in the public module header for encapsulation and so that I can use the typedef'd name in the definition.

Example:
typdef struct TheName TheName;
struct TheName{
int var;
TheName *p_link;
};
In the answers here, up to now, we find two ways of changing the JRE locale setting:
Programatically, using Locale.setDefault() (which, in my case, was the solution, since I didn't want to require any action of the user):
Locale.setDefault(new Locale("pt", "BR"));
Via arguments to the JVM:
java -jar anApp.jar -Duser.language=pt-BR
But, just as reference, I want to note that, on Windows, there is one more way of changing the locale used by the JRE, as documented here: changing the system-wide language.
Note: You must be logged in with an account that has Administrative Privileges.
Click Start > Control Panel.
Windows 7 and Vista: Click Clock, Language and Region > Region and Language.
Windows XP: Double click the Regional and Language Options icon.
The Regional and Language Options dialog box appears.
Windows 7: Click the Administrative tab.
Windows XP and Vista: Click the Advanced tab.
(If there is no Advanced tab, then you are not logged in with administrative privileges.)
Under the Language for non-Unicode programs section, select the desired language from the drop down menu.
Click OK.
The system displays a dialog box asking whether to use existing files or to install from the operating system CD. Ensure that you have the CD ready.
Follow the guided instructions to install the files.
Restart the computer after the installation is complete.
Certainly on Linux the JRE also uses the system settings to determine which locale to use, but the instructions to set the system-wide language change from distro to distro.
As of PostgreSQL 9.3, you can use the command pg_isready
to determine the connection status of a PostgreSQL server.
From the docs:
pg_isready returns 0 to the shell if the server is accepting connections normally, 1 if the server is rejecting connections (for example during startup), 2 if there was no response to the connection attempt, and 3 if no attempt was made (for example due to invalid parameters).
(MyColours)Enum.Parse(typeof(MyColours), "red", true); // MyColours.Red
(int)((MyColours)Enum.Parse(typeof(MyColours), "red", true)); // 0
If you can live with 01 for January instead of 1, then try...
d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")
You can check the docs for other formatting directives.
For other Beginners (like myself) If you are on windows running git as admin also solves the problem.
To add a char to a std::string var using the append method, you need to use this overload:
std::string::append(size_type _Count, char _Ch)
Edit : Your're right I misunderstood the size_type parameter, displayed in the context help. This is the number of chars to add. So the correct call is
s.append(1, d);
not
s.append(sizeof(char), d);
Or the simpliest way :
s += d;
I agree with using events for this. Since I suspect that you're building an MDI-application (since you create many child forms) and creates windows dynamically and might not know when to unsubscribe from events, I would recommend that you take a look at Weak Event Patterns. Alas, this is only available for framework 3.0 and 3.5 but something similar can be implemented fairly easy with weak references.
However, if you want to find a control in a form based on the form's reference, it's not enough to simply look at the form's control collection. Since every control have it's own control collection, you will have to recurse through them all to find a specific control. You can do this with these two methods (which can be improved).
public static Control FindControl(Form form, string name)
{
foreach (Control control in form.Controls)
{
Control result = FindControl(form, control, name);
if (result != null)
return result;
}
return null;
}
private static Control FindControl(Form form, Control control, string name)
{
if (control.Name == name) {
return control;
}
foreach (Control subControl in control.Controls)
{
Control result = FindControl(form, subControl, name);
if (result != null)
return result;
}
return null;
}
Android 4.4 (Kit Kat) does have a new sniffing capability for Bluetooth. You should give it a try.
If you don’t own a sniffing device however, you aren’t necessarily out of luck. In many cases we can obtain positive results with a new feature introduced in Android 4.4: the ability to capture all Bluetooth HCI packets and save them to a file.
When the Analyst has finished populating the capture file by running the application being tested, he can pull the file generated by Android into the external storage of the device and analyze it (with Wireshark, for example).
Once this setting is activated, Android will save the packet capture to /sdcard/btsnoop_hci.log to be pulled by the analyst and inspected.
Type the following in case /sdcard/
is not the right path on your particular device:
adb shell echo \$EXTERNAL_STORAGE
We can then open a shell and pull the file: $adb pull /sdcard/btsnoop_hci.log and inspect it with Wireshark, just like a PCAP collected by sniffing WiFi traffic for example, so it is very simple and well supported:
You can enable this by going to Settings->Developer Options, then checking the box next to "Bluetooth HCI Snoop Log."
Why don't you want to remove the multiple
attribute? The entire purpose of that attribute is to specify to the browser that multiple values may be selected from the given select
element. If only a single value should be selected, remove the attribute and the browser will know to allow only a single selection.
Use the tools you have, that's what they're for.
If the indexes are continuous:
foreach ($arr as $key => $val) {
if (isset($arr[$key+1])) {
echo $arr[$key+1]; // next element
} else {
// end of array reached
}
}
img And You can use this kode
class Nokta:
def __init__(self,x,y):
self.x=x
self.y=y
class Dogru:
def __init__(self,a,b):
self.a=a
self.b=b
def Kesisim(self,Dogru_b):
x1= self.a.x
x2=self.b.x
x3=Dogru_b.a.x
x4=Dogru_b.b.x
y1= self.a.y
y2=self.b.y
y3=Dogru_b.a.y
y4=Dogru_b.b.y
#Notlardaki denklemleri kullandim
pay1=((x4 - x3) * (y1 - y3) - (y4 - y3) * (x1 - x3))
pay2=((x2-x1) * (y1 - y3) - (y2 - y1) * (x1 - x3))
payda=((y4 - y3) *(x2-x1)-(x4 - x3)*(y2 - y1))
if pay1==0 and pay2==0 and payda==0:
print("DOGRULAR BIRBIRINE ÇAKISIKTIR")
elif payda==0:
print("DOGRULAR BIRBIRNE PARALELDIR")
else:
ua=pay1/payda if payda else 0
ub=pay2/payda if payda else 0
#x ve y buldum
x=x1+ua*(x2-x1)
y=y1+ua*(y2-y1)
print("DOGRULAR {},{} NOKTASINDA KESISTI".format(x,y))
This also can happen if the device you are trying to run on has some older version of the provisioning profile you are using that points to an old, expired or revoked certificate or a certificate without associated private key. Delete any invalid Provisioning Profiles under your device section in Xcode organizer.
In my case I had one local commit, which wasn't pushed to origin\master
, but commited to my local master
branch. This local commit should be now pushed to another branch.
With Git Extensions you can do something like this:
You could also do that on the GIT command line. Example copied from David Christensen:
I think you'll find
git cherry-pick
+git reset
to be a much quicker workflow:Using your same scenario, with "feature" being the branch with the top-most commit being incorrect, it'd be much easier to do this:
git checkout master
git cherry-pick feature
git checkout feature
git reset --hard HEAD^
Saves quite a bit of work, and is the scenario that
git cherry-pick
was designed to handle.I'll also note that this will work as well if it's not the topmost commit; you just need a commitish for the argument to cherry-pick, via:
git checkout master
git cherry-pick $sha1
git checkout feature
git rebase -i ... # whack the specific commit from the history
I catch the next case about cors. Maybe it will be useful to somebody. If you add feature 'WebDav Redirector' to your server, PUT and DELETE requests are failed.
So, you will need to remove 'WebDAVModule' from your IIS server:
Or add to your config:
<system.webServer>
<modules>
<remove name="WebDAVModule"/>
</modules>
<handlers>
<remove name="WebDAV" />
...
</handlers>
In Rails, you can do:
Dir[Rails.root.join('lib', 'ext', '*.rb')].each { |file| require file }
Update: Corrected with suggestion of @Jiggneshh Gohel to remove slashes.
Take a look at the Wikipedia link
JavaScript, despite the name, is essentially unrelated to the Java programming language, although both have the common C syntax, and JavaScript copies many Java names and naming conventions. The language was originally named "LiveScript" but was renamed in a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with their then-dominant browser. The key design principles within JavaScript are inherited from the Self and Scheme programming languages.
You could also use viewport percentages if you don't care about old school IE.
height: 100vh;
You can use nil
about anywhere you can use null
. The main difference is that you can send messages to nil
, so you can use it in some places where null
cant work.
In general, just use nil
.
I'm completely revising my original answer because of points raised in the other questions and comments. Here is the new benchmark script:
import time
import numpy as np
def fancy_index_relu(m):
m[m < 0] = 0
relus = {
"max": lambda x: np.maximum(x, 0),
"in-place max": lambda x: np.maximum(x, 0, x),
"mul": lambda x: x * (x > 0),
"abs": lambda x: (abs(x) + x) / 2,
"fancy index": fancy_index_relu,
}
for name, relu in relus.items():
n_iter = 20
x = np.random.random((n_iter, 5000, 5000)) - 0.5
t1 = time.time()
for i in range(n_iter):
relu(x[i])
t2 = time.time()
print("{:>12s} {:3.0f} ms".format(name, (t2 - t1) / n_iter * 1000))
It takes care to use a different ndarray for each implementation and iteration. Here are the results:
max 126 ms
in-place max 107 ms
mul 136 ms
abs 86 ms
fancy index 132 ms
You can set the path from the current cmd window using the PATH =
command. That will only add it for the current cmd instance. if you want to add it permanently, you should add it to system variables. (Computer > Advanced System Settings > Environment Variables)
You would goto your cmd instance, and put in PATH=C:/Python27/;%PATH%
.
You need to change public void klik(PaintEventArgs pea, EventArgs e)
to public void klik(object sender, System.EventArgs e)
because there is no Click
event handler with parameters PaintEventArgs pea, EventArgs e
.
I tried a lot of these suggestions but noting seemed to work. I've wasted quite a few hours only to found out that this was my mistake:
@Scripts.Render("/bundles/foundation")
It always have me minified and bundled javascript, no matter what I tried. Instead, I should have used this:
@Scripts.Render("~/bundles/foundation")
The extra '~' did it. I've even removed it again in only one instance to see if that was really it. It was... hopefully I can save at least one person the hours I wasted on this.
I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.
android:layout_gravity
is used for the layout itself
Use android:gravity="center"
for children of your LinearLayout
So your code should be:
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_weight="1" >
SELECT id, GROUP_CONCAT(name SEPARATOR ' ') FROM table GROUP BY id;
https://dev.mysql.com/doc/refman/8.0/en/aggregate-functions.html#function_group-concat
From the link above, GROUP_CONCAT
: This function returns a string result with the concatenated non-NULL values from a group. It returns NULL if there are no non-NULL values.
If you want SQL Server to try and figure it out, just use CAST CAST('whatever' AS datetime) However that is a bad idea in general. There are issues with international dates that would come up. So as you've found, to avoid those issues, you want to use the ODBC canonical format of the date. That is format number 120, 20 is the format for just two digit years. I don't think SQL Server has a built-in function that allows you to provide a user given format. You can write your own and might even find one if you search online.
To check if something exits, you can use the PHP function isset() see php.net. This function will check if the variable is set and is not NULL.
Example:
if(isset($obj->a))
{
//do something
}
If you need to check if a property exists in a class, then you can use the build in function property_exists()
Example:
if (property_exists('class', $property)) {
//do something
}
RE. "Can we set this value for individual page" – MonsterMMORPG.

The above snippet is taken from the end of my own working web.config, which I tested yesterday - it works for me.
This is inspired by Holstebroe's answer, plus comments here: Getting an Image object from a byte array

Python 3 built-in exceptions have the strerror
field:
except ValueError as err:
err.strerror = "New error message"
raise err
I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.
The Pyhton 3 opening modes are:
'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)
The modes r
, w
, x
, a
are combined with the mode modifiers b
or t
. +
is optionally added, U
should be avoided.
As I found out the hard way, it is a good idea to always specify t
when opening a file in text mode since r
is an alias for rt
in the standard open()
function but an alias for rb
in the open()
functions of all compression modules (when e.g. reading a *.bz2
file).
Thus the modes for opening a file should be:
rt
/ wt
/ xt
/ at
for reading / writing / creating / appending to a file in text mode and
rb
/ wb
/ xb
/ ab
for reading / writing / creating / appending to a file in binary mode.
Use +
as before.
Use matplotlib
's calls that won't block:
Using draw()
:
from matplotlib.pyplot import plot, draw, show
plot([1,2,3])
draw()
print('continue computation')
# at the end call show to ensure window won't close.
show()
Using interactive mode:
from matplotlib.pyplot import plot, ion, show
ion() # enables interactive mode
plot([1,2,3]) # result shows immediatelly (implicit draw())
print('continue computation')
# at the end call show to ensure window won't close.
show()
To answer the original question specifically (using IO.FileAttributes):
Get-ChildItem c:\mypath -Recurse | Where-Object {$_.Attributes -and [IO.FileAttributes]::Directory}
I do prefer Marek's solution though (Where-Object { $_ -is [System.IO.DirectoryInfo] }
).
A little bit of update with ES6
classes instead of React.createClass
import React, { Component } from 'react';
class SomeComponent extends Component {
constructor(props) {
super(props);
// this code might be called when there is no element avaliable in `document` yet (eg. initial render)
}
componentDidMount() {
// this code will be always called when component is mounted in browser DOM ('after render')
}
render() {
return (
<div className="component">
Some Content
</div>
);
}
}
Also - check React component lifecycle methods:The Component Lifecycle
Every component have a lot of methods similar to componentDidMount
eg.
componentWillUnmount()
- component is about to be removed from browser DOMAt the time of writing, setting display:none
on the element didn't work for me. Setting the element's width and height to 0 did not work either. So the element has to be at least 1px
in width for this to work.
The following example worked in Chrome and Firefox:
const str = 'Copy me';
const el = document.createElement("input");
// Does not work:
// dummy.style.display = "none";
el.style.height = '0px';
// Does not work:
// el.style.width = '0px';
el.style.width = '1px';
document.body.appendChild(el);
el.value = str;
el.select();
document.execCommand("copy");
document.body.removeChild(el);
I'd like to add that I can see why the browsers are trying to prevent this hackish approach. It's better to openly show the content you are going copy into the user's browser. But sometimes there are design requirements, we can't change.
For Django users:
Recently came across TypeError: Decimal('2337.00') is not JSON serializable
while JSON encoding i.e. json.dumps(data)
Solution:
# converts Decimal, Datetime, UUIDs to str for Encoding
from django.core.serializers.json import DjangoJSONEncoder
json.dumps(response.data, cls=DjangoJSONEncoder)
But, now the Decimal value will be a string, now we can explicitly set the decimal/float value parser when decoding data, using parse_float
option in json.loads
:
import decimal
data = json.loads(data, parse_float=decimal.Decimal) # default is float(num_str)
Yes, you can do this use this below code it may help you.

Install Flask-SQLAlchemy with pip in your virtualenv:
pip install flask_sqlalchemy
Then import flask_sqlalchemy
in your code:
from flask_sqlalchemy import SQLAlchemy
If you're VSCode user, then you probably have Insert Spaces
option checked. This will replace every tab you press by spaces which leads to this issue. Uncheck it and you're good to go.
I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6.
Here's the pypi https://pypi.python.org/pypi/cx_Freeze
The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html
I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though.
For the Angular 7v
Change
import 'rxjs/add/operator/map';
To
import { map } from "rxjs/operators";
And
return this.http.get('http://localhost/ionicapis/public/api/products')
.pipe(map(res => res.json()));
Sometimes it is due to the master table is dropped (maybe by disabling foreign_key_checks), but the foreign key CONSTRAINT still exists in other tables. In my case I had dropped the table and tried to recreate it, but it was throwing the same error for me.
So try dropping all the foreign key CONSTRAINTs from all the tables if there are any and then update or create the table.
This happened because I had http
instead of https
in this:
<repository>
<id>jcenter</id>
<name>jcenter-bintray</name>
<url>https://jcenter.bintray.com</url>
</repository>
I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.
Correlated Subquery is a sub-query that uses values from the outer query. In this case the inner query has to be executed for every row of outer query.
See example here http://en.wikipedia.org/wiki/Correlated_subquery
Simple subquery doesn't use values from the outer query and is being calculated only once:
SELECT id, first_name
FROM student_details
WHERE id IN (SELECT student_id
FROM student_subjects
WHERE subject= 'Science');
CoRelated Subquery Example -
Query To Find all employees whose salary is above average for their department
SELECT employee_number, name
FROM employees emp
WHERE salary > (
SELECT AVG(salary)
FROM employees
WHERE department = emp.department);
Make sure HDFS is online. Start it by $HADOOP_HOME/sbin/start-dfs.sh
Once you do that, your test with telnet localhost 9001
should work.
Specific Table Migration
php artisan migrate --path=/database/migrations/fileName.php
You need a new version of notepad++. Looks like old versions don't support |
.
Note: egrep "CAT|TOWN"
will search for lines containing CATOWN. (CAT)|(TOWN)
is the proper or extension (matching 1,3,4). Strangely you wrote and which is btw (CAT.*TOWN)|(TOWN.*CAT)
You can load HTML page partial, in your case is everything inside div#mytable.
setTimeout(function(){
$( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds
more information read this http://api.jquery.com/load/
<button id="refresh-btn">Refresh Table</button>
<script>
$(document).ready(function() {
function RefreshTable() {
$( "#mytable" ).load( "your-current-page.html #mytable" );
}
$("#refresh-btn").on("click", RefreshTable);
// OR CAN THIS WAY
//
// $("#refresh-btn").on("click", function() {
// $( "#mytable" ).load( "your-current-page.html #mytable" );
// });
});
</script>
You can use values()
method:
For instance Status.values()[0]
will return PAUSE in your case, if you print it, toString()
will be called and "PAUSE" will be printed.
Code snippet for both recursive and non-recursive approaches:
//helper method to get the list of files from the HDFS path
public static List<String>
listFilesFromHDFSPath(Configuration hadoopConfiguration,
String hdfsPath,
boolean recursive) throws IOException,
IllegalArgumentException
{
//resulting list of files
List<String> filePaths = new ArrayList<String>();
//get path from string and then the filesystem
Path path = new Path(hdfsPath); //throws IllegalArgumentException
FileSystem fs = path.getFileSystem(hadoopConfiguration);
//if recursive approach is requested
if(recursive)
{
//(heap issues with recursive approach) => using a queue
Queue<Path> fileQueue = new LinkedList<Path>();
//add the obtained path to the queue
fileQueue.add(path);
//while the fileQueue is not empty
while (!fileQueue.isEmpty())
{
//get the file path from queue
Path filePath = fileQueue.remove();
//filePath refers to a file
if (fs.isFile(filePath))
{
filePaths.add(filePath.toString());
}
else //else filePath refers to a directory
{
//list paths in the directory and add to the queue
FileStatus[] fileStatuses = fs.listStatus(filePath);
for (FileStatus fileStatus : fileStatuses)
{
fileQueue.add(fileStatus.getPath());
} // for
} // else
} // while
} // if
else //non-recursive approach => no heap overhead
{
//if the given hdfsPath is actually directory
if(fs.isDirectory(path))
{
FileStatus[] fileStatuses = fs.listStatus(path);
//loop all file statuses
for(FileStatus fileStatus : fileStatuses)
{
//if the given status is a file, then update the resulting list
if(fileStatus.isFile())
filePaths.add(fileStatus.getPath().toString());
} // for
} // if
else //it is a file then
{
//return the one and only file path to the resulting list
filePaths.add(path.toString());
} // else
} // else
//close filesystem; no more operations
fs.close();
//return the resulting list
return filePaths;
} // listFilesFromHDFSPath
It is possible that the offset
could be a non-integer, using em
as the measurement unit, relative font-sizes
in %
.
I also theorise that the offset
might not be a whole number when the zoom
isn't 100%
but that depends how the browser handles scaling.
Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.
First the actual accounts:
LocalService account (preferred)
A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.
NT AUTHORITY\LocalService
HKEY_USERS\S-1-5-19
)
Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).
NT AUTHORITY\NetworkService
MANGO$
) to remote serversHKEY_USERS\S-1-5-20
)NETWORK SERVICE
into the Select User or Group dialog
LocalSystem account (dangerous, don't use!)
Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)
.\LocalSystem
(can also use LocalSystem
or ComputerName\LocalSystem
)HKCU
represents the default user)MANGO$
) to remote servers
Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService
can still access the internet.
The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).
It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.
In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).
In Windows Server 2003 you cannot run a scheduled task as
NT_AUTHORITY\LocalService
(aka the Local Service account), or NT AUTHORITY\NetworkService
(aka the Network Service account). That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.
A service running as NetworkService
presents the machine credentials on the network. This means that if your computer was called mango
, it would present as the machine account MANGO$
:
You can set up Maven's Surefire to run unit tests and integration tests separately. In the standard unit test phase you run everything that does not pattern match an integration test. You then create a second test phase that runs just the integration tests.
Here is an example:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<excludes>
<exclude>**/*IntegrationTest.java</exclude>
</excludes>
</configuration>
<executions>
<execution>
<id>integration-test</id>
<goals>
<goal>test</goal>
</goals>
<phase>integration-test</phase>
<configuration>
<excludes>
<exclude>none</exclude>
</excludes>
<includes>
<include>**/*IntegrationTest.java</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
You're not using splice correctly:
arr.splice(4, 1)
this will remove 1 item at index 4. see here
I think you want to use slice:
arr.slice(0,5)
this will return elements in position 0 through 4.
This assumes all the rest of your code (cookies etc) works correctly
Make sure you add the team on both Debug and Release tabs.
This worked for me:
File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)
clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.
Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.
then in:
Run >> Edit Configurations
Add this line to VM Options:
--module-path /path/to/JavaFX/lib --add-modules=javafx.controls
(oh and don't forget to set the SDK)
One option would be
const styleElement = getComputedStyle(document.getElementById("myDiv"));
console.log(styleElement.height);
&&
works by stringing-together multiple selectors like-so:
<div class="class1 class2"></div>
div.class1.class2
{
/* foo */
}
Another example:
<input type="radio" class="class1" />
input[type="radio"].class1
{
/* foo */
}
||
works by separating multiple selectors with commas like-so:
<div class="class1"></div>
<div class="class2"></div>
div.class1,
div.class2
{
/* foo */
}
Jonny 5 beat me to it. I was going to suggest using the \W+
without the \s
as in text.replace(/\W+/g, " ")
. This covers white space as well.
You see the two empty -D
entries in the g++
command line? They're causing the problem. You must have values in the -D
items e.g. -DWIN32
if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:
SYSTEM ?= generic
ENVIRONMENT ?= generic
in the makefile which gives them default values.
Your output looks to be missing the all important output:
<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers
just to clarify, what actually got sent to g++
was -D -DWindows_NT
, i.e. define a preprocessor macro called -DWindows_NT
; which is of course not a valid identifier (similarly for -D -I.
)
Go to folder and use the command:
svn co {url}
For classes that you create (ie. are not part of the Android) its possible to avoid the crash completely.
Any class that implements finalize()
has some unavoidable probability of crashing as explained by @oba. So instead of using finalizers to perform cleanup, use a PhantomReferenceQueue
.
For an example check out the implementation in React Native: https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/jni/DestructorThread.java
See if the XDT (web.config) transform engine can help you. Currently it's only natively supported for web projects, but technically there is nothing stopping you from using it in other application types. There are many guides on how to use XDT by manually editing the project files, but I found a plugin that works great: https://visualstudiogallery.msdn.microsoft.com/579d3a78-3bdd-497c-bc21-aa6e6abbc859
The plugin is only helping to setup the configuration, it's not needed to build and the solution can be built on other machines or on a build server without the plugin or any other tools being required.
If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.
First of all, where you're going wrong is the offset.
It should look more like this...
set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%
If the date was Tue 12/02/2013
then it would display it as 2013/02/12
.
To remove the slashes, the code would look more like
set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%
which would output 20130212
And a hint for doing it in the future, if mydate
equals something like %date:~10,4%%date:~7,2%
or the like, you probably forgot a tilde (~).
Here is the code that will not download courpt files
$filename = "myfile.jpg";
$file = "/uploads/images/".$filename;
header('Content-type: application/octet-stream');
header("Content-Type: ".mime_content_type($file));
header("Content-Disposition: attachment; filename=".$filename);
while (ob_get_level()) {
ob_end_clean();
}
readfile($file);
I have included mime_content_type which will return content type of file .
To prevent from corrupt file download i have added ob_get_level() and ob_end_clean();
What type of authentication do you use? Send the credentials using the properties Ben said before and setup a cookie handler. You already allow redirection, check your webserver if any redirection occurs (NTLM auth does for sure). If there is a redirection you need to store the session which is mostly stored in a session cookie.
If you want to finish and just add a resultCode
(without data), you can call setResult(int resultCode)
before finish()
.
For example:
...
if (everything_OK) {
setResult(Activity.RESULT_OK); // OK! (use whatever code you want)
finish();
}
else {
setResult(Activity.RESULT_CANCELED); // some error ...
finish();
}
...
Then in your calling activity, check the resultCode
, to see if we're OK.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == someCustomRequestCode) {
if (resultCode == Activity.RESULT_OK) {
// OK!
}
else if (resultCode = Activity.RESULT_CANCELED) {
// something went wrong :-(
}
}
}
Don't forget to call the activity with startActivityForResult(intent, someCustomRequestCode)
.
Paxdiablo's answer is absolutely correct.
To avoid writing the return value 1
twice, I would use this instead:
=IF(OR(ISBLANK(A1),TRIM(A1)=""),1,0)
Just restarting the system worked for me. It might be a temporary issue
The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date')
declare the date property like so: private _date: string;
. Also, make sure you are instantiating the model with the new
keyword. Lastly, access the property using regular dot notation.
Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :
let passcode = "secret passcode";
class Employee {
private _fullName: string;
get fullName(): string {
return this._fullName;
}
set fullName(newName: string) {
if (passcode && passcode == "secret passcode") {
this._fullName = newName;
}
else {
console.log("Error: Unauthorized update of employee!");
}
}
}
let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
console.log(employee.fullName);
}
And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview
I create 2 different methods to remove subview. And it's much easier to use if we put them in extension
extension UIView {
/// Remove all subview
func removeAllSubviews() {
subviews.forEach { $0.removeFromSuperview() }
}
/// Remove all subview with specific type
func removeAllSubviews<T: UIView>(type: T.Type) {
subviews
.filter { $0.isMember(of: type) }
.forEach { $0.removeFromSuperview() }
}
}
setting the tcp_reuse is more useful than changing time_wait, as long as you have the parameter (kernels 3.2 and above, unfortunately that disqualifies all versions of RHEL and XenServer).
Dropping the value, particularly for VPN connected users, can result in constant recreation of proxy tunnels on the outbound connection. With the default Netscaler (XenServer) config, which is lower than the default Linux config, Chrome will sometimes have to recreate the proxy tunnel up to a dozen times to retrieve one web page. Applications that don't retry, such as Maven and Eclipse P2, simply fail.
The original motive for the parameter (avoid duplication) was made redundant by a TCP RFC that specifies timestamp inclusion on all TCP requests.
The following worked for me:
Install Java 7u21 from here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html#jdk-7u21-oth-JPR
set these variables:
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home"
export PATH=$JAVA_HOME/bin:$PATH
Run your app and fun :)
(Minor update: put variable value in quote)
If you have two lists called 'a' and 'b', you can do: [m - n for m,n in zip(a,b)]
Example to implement callback method using interface.
Define the interface, NewInterface.java.
package javaapplication1;
public interface NewInterface {
void callback();
}
Create a new class, NewClass.java. It will call the callback method in main class.
package javaapplication1;
public class NewClass {
private NewInterface mainClass;
public NewClass(NewInterface mClass){
mainClass = mClass;
}
public void calledFromMain(){
//Do somthing...
//call back main
mainClass.callback();
}
}
The main class, JavaApplication1.java, to implement the interface NewInterface - callback() method. It will create and call NewClass object. Then, the NewClass object will callback it's callback() method in turn.
package javaapplication1;
public class JavaApplication1 implements NewInterface{
NewClass newClass;
public static void main(String[] args) {
System.out.println("test...");
JavaApplication1 myApplication = new JavaApplication1();
myApplication.doSomething();
}
private void doSomething(){
newClass = new NewClass(this);
newClass.calledFromMain();
}
@Override
public void callback() {
System.out.println("callback");
}
}
An alternative in Java 8:
String[] filteredArray = Arrays.stream(array)
.filter(e -> !e.equals(foo)).toArray(String[]::new);
With the commit introduced today (Nov 25), you can now specify a port number right after the run
or start
sbt commands.
For instance
play run 8080
or play start 8080
Play defaults to port 9000
I am not sure if the question is still active but due to the fact that I did not find the solution in the above answers I decided to write it down.
I use the following approach:
readinessProbe:
exec:
command:
- sh
- -c
- |
command1
command2 && command3
I know my example is related to readinessProbe, livenessProbe, etc. but suspect the same case is for the container commands. This provides flexibility as it mirrors a standard script writing in Bash.
JDBC does not support this option (although a specific DB driver may offer this). Anyway, there should not be a problem with loading all file contents into memory.
Description:
there are 3 steps to run PHP code inside post or page.
In functions.php
file (in your theme) add new function
In functions.php
file (in your theme) register new shortcode which call your function:
add_shortcode( 'SHORCODE_NAME', 'FUNCTION_NAME' );
Example #1: just display text.
In functions:
function simple_function_1() {
return "Hello World!";
}
add_shortcode( 'own_shortcode1', 'simple_function_1' );
In post/page:
[own_shortcode1]
Effect:
Hello World!
Example #2: use for loop.
In functions:
function simple_function_2() {
$output = "";
for ($number = 1; $number < 10; $number++) {
// Append numbers to the string
$output .= "$number<br>";
}
return "$output";
}
add_shortcode( 'own_shortcode2', 'simple_function_2' );
In post/page:
[own_shortcode2]
Effect:
1
2
3
4
5
6
7
8
9
Example #3: use shortcode with arguments
In functions:
function simple_function_3($name) {
return "Hello $name";
}
add_shortcode( 'own_shortcode3', 'simple_function_3' );
In post/page:
[own_shortcode3 name="John"]
Effect:
Hello John
Example #3 - without passing arguments
In post/page:
[own_shortcode3]
Effect:
Hello
You can get the maximum like this:
>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]]
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]].max(axis=1)
0 1
1 8
2 3
and so:
>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If you know that "A" and "B" are the only columns, you could even get away with
>>> df["C"] = df.max(axis=1)
And you could use .apply(max, axis=1)
too, I guess.
Simply should be normalized chain and run a replacement codes:
var str = "Letras Á É Í Ó Ú Ñ - á é í ó ú ñ...";
console.log (str.normalize ("NFKD").replace (/[\u0300-\u036F]/g, ""));
// Letras A E I O U N - a e i o u n...
See normalize
Then you can use this function:
function noTilde (s) {
if (s.normalize != undefined) {
s = s.normalize ("NFKD");
}
return s.replace (/[\u0300-\u036F]/g, "");
}
is just going to look for a div with class="outer inner", is that correct?
No, '.outer .inner'
will look for all elements with the .inner class that also have an element with the .outer class as an ancestor. '.outer.inner'
(no space) would give the results you're thinking of.
'.outer > .inner'
will look for immediate children of an element with the .outer class for elements with the .inner class.
Both '.outer .inner'
and '.outer > .inner'
should work for your example, although the selectors are fundamentally different and you should be wary of this.
How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:
Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.
Actually the XSD is XML itself. Its purpose is to validate the structure of another XML document. The XSD is not mandatory for any XML, but it assures that the XML could be used for some particular purposes. The XML is only containing data in suitable format and structure.
There is no need to invoke PHP for this. Just put it directly into the HTML:
<a href="http://www.example.com/">...
We will be looking at two approaches to achieve this. With and without using jQuery.
You need to add a keyup function to both of your password and confirm password fields. The reason being that the text equality should be checked even if the password
field changes. Thanks @kdjernigan for pointing that out
In this way, when you type in the field you will know if the password is same or not:
$('#password, #confirm_password').on('keyup', function () {
if ($('#password').val() == $('#confirm_password').val()) {
$('#message').html('Matching').css('color', 'green');
} else
$('#message').html('Not Matching').css('color', 'red');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<label>confirm password:
<input type="password" name="confirm_password" id="confirm_password" />
<span id='message'></span>
</label>
_x000D_
and here is the fiddle: http://jsfiddle.net/aelor/F6sEv/325/
We will use the onkeyup event of javascript on both the fields to achieve the same effect.
var check = function() {
if (document.getElementById('password').value ==
document.getElementById('confirm_password').value) {
document.getElementById('message').style.color = 'green';
document.getElementById('message').innerHTML = 'matching';
} else {
document.getElementById('message').style.color = 'red';
document.getElementById('message').innerHTML = 'not matching';
}

Are you able to hit that URL by browser or by PHP script? The error shown is that you could not connect. So first confirm that the URL is accessible.
convert your inputs to ints:
width = int(input())
height = int(input())
The order of items in the PATH matters. If there are multiple entries for various java installations, the first one in your PATH will be used.
I have had similar issues after installing a product, like Oracle, that puts it's JRE at the beginning of the PATH.
Ensure that the JDK you want to be loaded is the first entry in your PATH (or at least that it appears before C:\Program Files\Java\jre6\bin
appears).
You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:
/**
* Used to stitch together functional operators into a chain.
* @method pipe
* @return {Observable} the Observable result of all of the operators having
* been called in the order they were passed in.
*
* @example
*
* import { map, filter, scan } from 'rxjs/operators';
*
* Rx.Observable.interval(1000)
* .pipe(
* filter(x => x % 2 === 0),
* map(x => x + x),
* scan((acc, x) => acc + x)
* )
* .subscribe(x => console.log(x))
*/
Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan()
, but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe()
to make a chain of those operators (see example above).
Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do()
. You can think of it as if observable was an array over time, then tap()
would be an equivalent to Array.forEach()
.
I know that my answer came late but it happens to me today and I solved it with the following approach:
^(([A-Z]+),)+([A-Z]+)$
So the first group (([A-Z]+),)+
will match all the repeated patterns except the final one ([A-Z]+)
that will match the final one. and this will be dynamic no matter how many repeated groups in the string.
Since Horse
is a subclass of Animal
, you can just change
print(Animal.SIZES[1])
with
print(self.SIZES[1])
Still, you need to remember that SIZES[1]
means "big", so probably you could improve your code by doing something like:
class Animal:
SIZE_HUGE="Huge"
SIZE_BIG="Big"
SIZE_MEDIUM="Medium"
SIZE_SMALL="Small"
class Horse(Animal):
def printSize(self):
print(self.SIZE_BIG)
Alternatively, you could create intermediate classes: HugeAnimal
, BigAnimal
, and so on. That would be especially helpful if each animal class will contain different logic.

Use DATESTR
>> datestr(40189)
ans =
12-Jan-0110
Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM
>> datenum(2010,1,11)
ans =
734149
>> datenum(2010,1,11)-40189
ans =
693960
>> datestr(40189+693960)
ans =
11-Jan-2010
In other words, to convert any serial Excel date, call
datestr(excelSerialDate + 693960)
EDIT
To get the date in mm/dd/yyyy format, call datestr
with the specified format
excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010
Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things
excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

I was able to adapt these instructions take a table with an existing non-increment primary key, and add an incrementing primary key to the table and create a new composite primary key with both the old and new keys as a composite primary key using the following code:
DROP TABLE IF EXISTS SAKAI_USER_ID_MAP;
CREATE TABLE SAKAI_USER_ID_MAP (
USER_ID VARCHAR (99) NOT NULL,
EID VARCHAR (255) NOT NULL,
PRIMARY KEY (USER_ID)
);
INSERT INTO SAKAI_USER_ID_MAP VALUES ('admin', 'admin');
INSERT INTO SAKAI_USER_ID_MAP VALUES ('postmaster', 'postmaster');
ALTER TABLE SAKAI_USER_ID_MAP
DROP PRIMARY KEY,
ADD _USER_ID INT AUTO_INCREMENT NOT NULL FIRST,
ADD PRIMARY KEY ( _USER_ID, USER_ID );
When this is done, the _USER_ID field exists and has all number values for the primary key exactly as you would expect. With the "DROP TABLE" at the top, you can run this over and over to experiment with variations.
What I have not been able to get working is the situation where there are incoming FOREIGN KEYs that already point at the USER_ID field. I get this message when I try to do a more complex example with an incoming foreign key from another table.
#1025 - Error on rename of './zap/#sql-da07_6d' to './zap/SAKAI_USER_ID_MAP' (errno: 150)
I am guessing that I need to tear down all foreign keys before doing the ALTER table and then rebuild them afterwards. But for now I wanted to share this solution to a more challenging version of the original question in case others ran into this situation.
container
class has 15px left & right padding, so if you want to remove this padding, use following, because row
class has -15px left & right margin.
<div class="container">
<div class="row">
<img class='img-responsive' src="#" alt="" />
</div>
</div>
You can use basic css to achieve smooth scroll

As well as Amateras you could try Web Tools Project or Aptana. Although they will both give you way more than just a jsp editor.
Edit 2010/10/26 (comment from Simon Gibbs):
The Web Tools Project JSP editor is in the "Web Page Editor (Optional)" project.
Edit 2016/08/16 (extended comment from Dan Carter):
From Kepler (Eclipse 4.3.x) on, this is called "JSF Tools - Web Page Editor".
Let's say you have a url like this http://www.example.com/controller/action/arg1/arg2
If you want to know what are the arguments that are being passed in this url
$param_offset=0;
$params = array_slice($this->uri->rsegment_array(), $param_offset);
var_dump($params);
Output will be:
array (size=2)
0 => string 'arg1'
1 => string 'arg2'
Let uses a more immediate block level limited scope whereas var is function scope or global scope typically.
It seems let was chosen most likely because it is found in so many other languages to define variables, such as BASIC, and many others.

I'd prefer not to use an HTML5 only element such as <section>
. Also grouping the input fields might painful if you try to generate the form with code. It's always better to produce similar markup for each one and only change the class names. Therefore I would recommend a solution that looks like this :
CSS
label, input {
display: block;
}
ul.form {
width : 500px;
padding: 0px;
margin : 0px;
list-style-type: none;
}
ul.form li {
width : 500px;
}
ul.form li input {
width : 200px;
}
ul.form li textarea {
width : 450px;
height: 150px;
}
ul.form li.twoColumnPart {
float : left;
width : 250px;
}
HTML
<form name="message" method="post">
<ul class="form">
<li class="twoColumnPart">
<label for="name">Name</label>
<input id="name" type="text" value="" name="name">
</li>
<li class="twoColumnPart">
<label for="email">Email</label>
<input id="email" type="text" value="" name="email">
</li>
<li>
<label for="subject">Subject</label>
<input id="subject" type="text" value="" name="subject">
</li>
<li>
<label for="message">Message</label>
<textarea id="message" type="text" name="message"></textarea>
</li>
</ul>
</form>

If you're in an async function you can simply do it in one line:
console.log(1);
await new Promise(resolve => setTimeout(resolve, 3000)); // 3 sec
console.log(2);
FYI, if target is NodeJS you can use this if you want (it's a predefined promisified setTimeout function):
await setTimeout[Object.getOwnPropertySymbols(setTimeout)[0]](3000) // 3 sec
byte[] toByteArray(int value) {
return ByteBuffer.allocate(4).putInt(value).array();
}
byte[] toByteArray(int value) {
return new byte[] {
(byte)(value >> 24),
(byte)(value >> 16),
(byte)(value >> 8),
(byte)value };
}
int fromByteArray(byte[] bytes) {
return ByteBuffer.wrap(bytes).getInt();
}
// packing an array of 4 bytes to an int, big endian, minimal parentheses
// operator precedence: <<, &, |
// when operators of equal precedence (here bitwise OR) appear in the same expression, they are evaluated from left to right
int fromByteArray(byte[] bytes) {
return bytes[0] << 24 | (bytes[1] & 0xFF) << 16 | (bytes[2] & 0xFF) << 8 | (bytes[3] & 0xFF);
}
// packing an array of 4 bytes to an int, big endian, clean code
int fromByteArray(byte[] bytes) {
return ((bytes[0] & 0xFF) << 24) |
((bytes[1] & 0xFF) << 16) |
((bytes[2] & 0xFF) << 8 ) |
((bytes[3] & 0xFF) << 0 );
}
When packing signed bytes into an int, each byte needs to be masked off because it is sign-extended to 32 bits (rather than zero-extended) due to the arithmetic promotion rule (described in JLS, Conversions and Promotions).
There's an interesting puzzle related to this described in Java Puzzlers ("A Big Delight in Every Byte") by Joshua Bloch and Neal Gafter . When comparing a byte value to an int value, the byte is sign-extended to an int and then this value is compared to the other int
byte[] bytes = (…)
if (bytes[0] == 0xFF) {
// dead code, bytes[0] is in the range [-128,127] and thus never equal to 255
}
Note that all numeric types are signed in Java with exception to char being a 16-bit unsigned integer type.
No, you don't want to store it as a single string in your database like that.
You could use serialize()
but this will make your data harder to search, harder to work with, and wastes space.
You could do some other encoding as well, but it's generally prone to the same problem.
The whole reason you have a DB is so you can accomplish work like this trivially. You don't need a table to store arrays, you need a table that you can represent as an array.
Example:
id | word
1 | Sports
2 | Festivals
3 | Classes
4 | Other
You would simply select the data from the table with SQL, rather than have a table that looks like:
id | word
1 | Sports|Festivals|Classes|Other
That's not how anybody designs a schema in a relational database, it totally defeats the purpose of it.
I'll try a 4th grade explanation:
Things are very simple. A prototype
is an example of how something should be built. So:
I'm a function
and I build new objects similar to my prototype
I'm an object
and I was built using my __proto__
as an example
proof:
function Foo() { }
var bar = new Foo()
// `bar` is constructed from how Foo knows to construct objects
bar.__proto__ === Foo.prototype // => true
// bar is an instance - it does not know how to create objects
bar.prototype // => undefined
There are many ways to do it, but this is pretty simple and avoids issues with disrupting inline content positioning. You might need to adjust for margins/padding, too.
#backdrop, #curtain {
height: 100px;
width: 200px;
}
#curtain {
position: relative;
top: -100px;
}
function UniqueDateTime(format='',language='en-US'){
//returns a meaningful unique number based on current time, and milliseconds, making it virtually unique
//e.g : 20170428-115833-547
//allows personal formatting like more usual :YYYYMMDDHHmmSS, or YYYYMMDD_HH:mm:SS
var dt = new Date();
var modele="YYYYMMDD-HHmmSS-mss";
if (format!==''){
modele=format;
}
modele=modele.replace("YYYY",dt.getFullYear());
modele=modele.replace("MM",(dt.getMonth()+1).toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("DD",dt.getDate().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("HH",dt.getHours().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mm",dt.getMinutes().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("SS",dt.getSeconds().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mss",dt.getMilliseconds().toLocaleString(language, {minimumIntegerDigits: 3, useGrouping:false}));
return modele;
}
Use FormulaR1C1:
Cells((1,3),(10,3)).FormulaR1C1 = "=RC[-2]+RC[-1]"
Unlike Formula, FormulaR1C1 has relative referencing.
You can use ^ or 0 (Zero) in normal mode to move to the beginning of a line.
^ moves the cursor to the first non-blank character of a line
0 always moves the cursor to the "first column"
You can also use Shifti to move and switch to Insert mode.
Just return your existing check from a function.
function _isCurl(){
return function_exists('curl_version');
}
If you need fast lookup (basically constant time) of a object stored in your collection you should use Map instead of List.
If you need fast iteration of the objects you should use List.
So in your case...
Map<String,Customer> customers = new HashMap<String,Customer>();
//somewhere in the code you fill up the Map, assuming customer names are unique
customers.put(customer.getName(), customer)
// at some later point you retrieve it like this;
// this is fast, given a good hash
// been calculated for the "keys" in your map, in this case the keys are unique
// String objects so the default hash algorithm should be fine
Customer theCustomerYouLookFor = customers.get("Doe");
// modify it
theCustomerYouLookFor.setEmail("[email protected]")
use this code:
import pandas as pd
from datetime import datetime
print(pd.DatetimeIndex(df['give_date']).day)
Just another way to convert hex string to java string:
public static String unHex(String arg) {
String str = "";
for(int i=0;i<arg.length();i+=2)
{
String s = arg.substring(i, (i + 2));
int decimal = Integer.parseInt(s, 16);
str = str + (char) decimal;
}
return str;
}
In pure Python:
def get_param_from_url(url, param_name):
return [i.split("=")[-1] for i in url.split("?", 1)[-1].split("&") if i.startswith(param_name + "=")][0]
My situation was that I have a bare repo that the team pushes to, and a clone of that sitting right next to it. This set of lines in a Makefile work correctly for me:
git reset --hard
git remote update --prune
git pull --rebase --all
git cherry-pick -n remotes/origin/$(BRANCH)
By keeping the master of the bare repo up to date, we are able to cherry-pick a proposed change published to the bare repo. We also have a (more complicated) way to cherry-pick multiple braches for consolidated review and testing.
If "knows nothing" means "can't be used as a remote", then this doesn't help, but this SO question came up as I was googling around to come up with this workflow so I thought I'd contribute back.
This happened to me too! But I accidentally found out that execute the 'mysqld' command can solve your problem.

I create the dialog using AlertDialog.Builder so I used Rodrigo's answer inside a OnShowListener.
dialog.setOnShowListener(new OnShowListener() {
@Override
public void onShow(DialogInterface dialogInterface) {
Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics outMetrics = new DisplayMetrics ();
display.getMetrics(outMetrics);
dialog.getWindow().setLayout((int)(312 * outMetrics.density), (int)(436 * outMetrics.density));
}
});
To start only stopped containers:
docker start $(docker ps -a -q -f status=exited)
(On windows it works in Powershell).
Try following these steps:
If you have installed using Homebrew, the below command should be enough.
brew services restart postgresql
This sometimes might not work. In that case, the below two commands should definitely work:
rm /usr/local/var/postgres/postmaster.pid
pg_ctl -D /usr/local/var/postgres start
Usually a back-reference is either $1
or \1
(backslash one) for the first capture group (the first match of a pattern in parentheses), and indeed Sublime supports both syntaxes. So try:
my name used to be \1
or
my name used to be $1
Also note that your original capture pattern:
my name is (\w)+
is incorrect and will only capture the final letter of the name rather than the whole name. You should use the following pattern to capture all of the letters of the name:
my name is (\w+)
You have two options to abruptly exit out of ForEach-Object
pipeline in PowerShell:
Where-Object
first, then pass objects to Foreach-Object
, orForeach-Object
into a standard Foreach
looping construct.Let's see examples: Following scripts exit out of Foreach-Object loop after 2nd iteration (i.e. pipeline iterates only 2 times)":
Solution-1: use Where-Object
filter BEFORE Foreach-Object
:
[boolean]$exit = $false;
1..10 | Where-Object {$exit -eq $false} | Foreach-Object {
if($_ -eq 2) {$exit = $true} #OR $exit = ($_ -eq 2);
$_;
}
OR
1..10 | Where-Object {$_ -le 2} | Foreach-Object {
$_;
}
Solution-2: Converted Foreach-Object
into standard Foreach
looping construct:
Foreach ($i in 1..10) {
if ($i -eq 3) {break;}
$i;
}
PowerShell should really provide a bit more straightforward way to exit or break out from within the body of a Foreach-Object
pipeline. Note: return
doesn't exit, it only skips specific iteration (similar to continue
in most programming languages), here is an example of return
:
Write-Host "Following will only skip one iteration (actually iterates all 10 times)";
1..10 | Foreach-Object {
if ($_ -eq 3) {return;} #skips only 3rd iteration.
$_;
}

If you are to replace a fixed string or some pattern, I would also like to add the bash builtin pattern string replacement variable substitution construct. Instead of describing it myself, I am quoting the section from the bash manual:
${parameter/pattern/string}
The pattern is expanded to produce a pattern just as in pathname expansion. parameter is expanded and the longest match of pattern against its value is replaced with string. If pattern begins with
/
, all matches of pattern are replaced with string. Normally only the first match is replaced. If pattern begins with#
, it must match at the beginning of the expanded value of parameter. If pattern begins with%
, it must match at the end of the expanded value of parameter. If string is null, matches of pattern are deleted and the/
following pattern may be omitted. If parameter is@
or*
, the substitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable subscripted with@
or*
, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.
The #
means that it matches the id
of an element. The .
signifies the class name:
<div id="myRedText">This will be red.</div>
<div class="blueText">this will be blue.</div>
#myRedText {
color: red;
}
.blueText {
color: blue;
}
Note that in a HTML document, the id attribute must be unique, so if you have more than one element needing a specific style, you should use a class name.
I am a quite newbie to python and I was having same issue. (windows x64 os) I have solved, doing below steps
I'm guessing here, based on issues I've had in the past which I did solve:
I ended up with two solutions. My original solution was based on using rsh. Since then, most of our servers have had ssh installed, which has made this easier.
Using rsh, I put together a table of machines vs OS vs custom options which would guide this process in perl. Bourne shell wasn't sufficient, and we don't have bash on Sun or HP machines (and didn't have bash on AIX at the time - AIX 5L wasn't out yet). Korn shell wasn't much of an option, either, since most of our Linux boxes don't have pdksh installed. But, if you don't face these limitations, you can implement the idea in ksh or bash, I think.
Anyway, I would basically run 'rsh $machine -l $user "$cmd"' where $machine, of course, was the machine I was logging in to, $user, similarly obvious (though when I was going in as "root" this had some variance as we have multiple roots on some machines for reasons I don't fully understand), and $cmd was basically "DISPLAY=$DISPLAY xterm", though if I were launching konsole, for example, $cmd would be "konsole --display=$DISPLAY". Since $DISPLAY was being evaluated locally (where it's set properly), and not being passed literally across rsh, the display would always be set correctly.
I also had to make sure that no one did anything silly like reset DISPLAY if it was already set.
Now, I just use ssh, make sure that X11Forwarding is set to yes on the server (sshd_config), and then I can just ssh to the machine, let X commands go across the wire encrypted, and it'll always go back to the right place.

Now synchronise your project and also build your project.
Make sure your git username and password is correct. In my case, it gave error when the username and password(especially the GIT TOKEN) was not correct.
Also could be like this
df.filter(col('bar').isin(['a','b']) == False).show()
It will give consistent behavior for add/remove operations. But while iterating you have to explicitly synchronized. Refer this link

This smells of something that should be done with a JOIN instead. Can you share the larger problem with us?
Hey, I should be able to get this down to a single statement, but I haven't had time to play with it further yet today and may not get to. In the mean-time, know that you should be able to edit the query for your inner cursor to create the row numbers as part of the query using the ROW_NUMBER() function. From there, you can fold the inner cursor into the outer by doing an INNER JOIN on it (you can join on a sub query). Finally, any SELECT statement can be converted to an UPDATE using this method:
UPDATE [YourTable/Alias]
SET [Column] = q.Value
FROM
(
... complicate select query here ...
) q
Where [YourTable/Alias]
is a table or alias used in the select query.
A simple query which works for me is:
select * from table where DATEADD(month, 1,DATEFIELD) >= getdate()
You can use std::nextafter
with a fixed factor
of the epsilon
of a value like the following:
bool isNearlyEqual(double a, double b)
{
int factor = /* a fixed factor of epsilon */;
double min_a = a - (a - std::nextafter(a, std::numeric_limits<double>::lowest())) * factor;
double max_a = a + (std::nextafter(a, std::numeric_limits<double>::max()) - a) * factor;
return min_a <= b && max_a >= b;
}
For me a DNS name of my server was added to /etc/hosts and it was mapped to 127.0.0.1 which resulted in
SL23_GET_SERVER_HELLO:unknown protocol
Removing mapping of my real DNS name to 127.0.0.1 resolved the problem.
As per your request I have put this in an answer for you.
As Hieu Nguyen suggested in his answer, you can use the ajaxurl javascript variable to reference the admin-ajax.php file. However this variable is not declared on the frontend. It is simple to declare this on the front end, by putting the following in the header.php of your theme.
<script type="text/javascript">
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
</script>
As is described in the Wordpress AJAX documentation, you have two different hooks - wp_ajax_(action), and wp_ajax_nopriv_(action). The difference between these is:
Everything else is described in the documentation linked above. Happy coding!
P.S. Here is an example that should work. (I have not tested)
Front end:
<script type="text/javascript">
jQuery.ajax({
url: ajaxurl,
data: {
action: 'my_action_name'
},
type: 'GET'
});
</script>
Back end:
<?php
function my_ajax_callback_function() {
// Implement ajax function here
}
add_action( 'wp_ajax_my_action_name', 'my_ajax_callback_function' ); // If called from admin panel
add_action( 'wp_ajax_nopriv_my_action_name', 'my_ajax_callback_function' ); // If called from front end
?>
UPDATE Even though this is an old answer, it seems to keep getting thumbs up from people - which is great! I think this may be of use to some people.
WordPress has a function wp_localize_script. This function takes an array of data as the third parameter, intended to be translations, like the following:
var translation = {
success: "Success!",
failure: "Failure!",
error: "Error!",
...
};
So this simply loads an object into the HTML head tag. This can be utilized in the following way:
Backend:
wp_localize_script( 'FrontEndAjax', 'ajax', array(
'url' => admin_url( 'admin-ajax.php' )
) );
The advantage of this method is that it may be used in both themes AND plugins, as you are not hard-coding the ajax URL variable into the theme.
On the front end, the URL is now accessible via ajax.url
, rather than simply ajaxurl
in the previous examples.
Till we have a better solution, you can use the following:
duplicateObject = <YourObjType> JSON.parse(JSON.stringify(originalObject));
EDIT: Clarification
Please note: The above solution was only meant to be a quick-fix one liner, provided at a time when Angular 2 was under active development. My hope was we might eventually get an equivalent of angular.copy()
. Therefore I did not want to write or import a deep-cloning library.
This method also has issues with parsing date properties (it will become a string).
Please do not use this method in production apps. Use it only in your experimental projects - the ones you are doing for learning Angular 2.
In my case, android studio selectively doesnt recognize my device for projects with COMPILE AND TARGET SDKVERSION 29 under the app level build.gradle.
I fixed this either by downloading 'sources for android 29' which comes up after clicking the 'show package details' under the sdk manager tab or by reducing the compile and targetsdkversions to 28
You will need to use the IO.Directory.GetFiles function.
Dim files() As String = IO.Directory.GetFiles("c:\")
For Each file As String In files
' Do work, example
Dim text As String = IO.File.ReadAllText(file)
Next
[[[UIDevice currentDevice] systemVersion] floatValue]
Firstly, it will help if you set the headers of your PHP to serve JSON:
header('Content-type: application/json');
Secondly, it will help to adjust your ajax call:
$.ajax({
url: "main.php",
type: "POST",
dataType: "json",
data: {"action": "loadall", "id": id},
success: function(data){
console.log(data);
},
error: function(error){
console.log("Error:");
console.log(error);
}
});
If successful, the response you receieve should be picked up as true JSON and an object should be logged to console.
NOTE: If you want to pick up pure html, you might want to consider using another method to JSON, but I personally recommend using JSON and rendering it into html using templates (such as Handlebars js).
my two cents about logic:
syntax is "old date" - :"new date", so:
SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')
gives 30,
SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')
gives: -40

If #uploadedfile
is an input with type "file" :
var file = $("#uploadedfile")[0].files[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
Normally this would fire on the change event, like so:
$("#uploadedfile").on("change", function(){
var file = this.files[0],
fileName = file.name,
fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
CustomFileHandlingFunction(file);
});
This one works for me:
<?php
if(isset($_GET['action']))
{
//your code
echo 'Welcome';
}
?>
<form id="frm" method="post" action="?action" >
<input type="submit" value="Submit" id="submit" />
</form>

Simple Swift 3 Solution: Add this function to your view controllers that feature a text field:
@IBAction func textField(_ sender: AnyObject) {
self.view.endEditing(true);
}
Then open up your assistant editor and ensure both your Main.storyboard is on one side of your view and the desired view controller.swift file is on the other. Click on a text field and then select from the right hand side utilities panel 'Show the Connection Inspector' tab. Control drag from the 'Did End on Exit' to the above function in your swift file. Repeat for any other textfield in that scene and link to the same function.
In my case I checked event logs and found error was Cannot read configuration file ' trying to read configuration data from file '\\?\', line number '0'. The data field contains the error code.
The error code was 2307.
I deleted all files in C:\inetpub\temp\appPools and restarted the iis. It fixed the issue.
I found a solution by myself after doing some research:
Now everything works fine.
The example below includes scrolling behaviour if the content of the expanded centre component extends past its bounds. Also the centre component takes 100% of remaining space in the viewport.
html, body, .r_flex_container{
height: 100%;
display: flex;
flex-direction: column;
background: red;
margin: 0;
}
.r_flex_container {
display:flex;
flex-flow: column nowrap;
background-color:blue;
}
.r_flex_fixed_child {
flex:none;
background-color:black;
color:white;
}
.r_flex_expand_child {
flex:auto;
background-color:yellow;
overflow-y:scroll;
}
Example of html that can be used to demonstrate this behaviour
<html>
<body>
<div class="r_flex_container">
<div class="r_flex_fixed_child">
<p> This is the fixed 'header' child of the flex container </p>
</div>
<div class="r_flex_expand_child">
<article>this child container expands to use all of the space given to it - but could be shared with other expanding childs in which case they would get equal space after the fixed container space is allocated.

SQL JOIN
?SQL JOIN
is a method to retrieve data from two or more database tables.
SQL JOIN
s ?There are a total of five JOIN
s. They are :
1. JOIN or INNER JOIN
2. OUTER JOIN
2.1 LEFT OUTER JOIN or LEFT JOIN
2.2 RIGHT OUTER JOIN or RIGHT JOIN
2.3 FULL OUTER JOIN or FULL JOIN
3. NATURAL JOIN
4. CROSS JOIN
5. SELF JOIN
In this kind of a JOIN
, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.
In other words, INNER JOIN
is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.
Note that a JOIN
without any other JOIN
keywords (like INNER
, OUTER
, LEFT
, etc) is an INNER JOIN
. In other words, JOIN
is
a Syntactic sugar for INNER JOIN
(see: Difference between JOIN and INNER JOIN).
OUTER JOIN
retrieves
Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).
There are three kinds of Outer Join :
2.1 LEFT OUTER JOIN or LEFT JOIN
This join returns all the rows from the left table in conjunction with the matching rows from the
right table. If there are no columns matching in the right table, it returns NULL
values.
2.2 RIGHT OUTER JOIN or RIGHT JOIN
This JOIN
returns all the rows from the right table in conjunction with the matching rows from the
left table. If there are no columns matching in the left table, it returns NULL
values.
2.3 FULL OUTER JOIN or FULL JOIN
This JOIN
combines LEFT OUTER JOIN
and RIGHT OUTER JOIN
. It returns rows from either table when the conditions are met and returns NULL
value when there is no match.
In other words, OUTER JOIN
is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.
Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.
It is based on the two conditions :
JOIN
is made on all the columns with the same name for equality.This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.
It is the Cartesian product of the two tables involved. The result of a CROSS JOIN
will not make sense
in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).
It is not a different form of JOIN
, rather it is a JOIN
(INNER
, OUTER
, etc) of a table to itself.
Depending on the operator used for a JOIN
clause, there can be two types of JOIN
s. They are
For whatever JOIN
type (INNER
, OUTER
, etc), if we use ONLY the equality operator (=), then we say that
the JOIN
is an EQUI JOIN
.
This is same as EQUI JOIN
but it allows all other operators like >, <, >= etc.
Many consider both
EQUI JOIN
and ThetaJOIN
similar toINNER
,OUTER
etcJOIN
s. But I strongly believe that its a mistake and makes the ideas vague. BecauseINNER JOIN
,OUTER JOIN
etc are all connected with the tables and their data whereasEQUI JOIN
andTHETA JOIN
are only connected with the operators we use in the former.Again, there are many who consider
NATURAL JOIN
as some sort of "peculiar"EQUI JOIN
. In fact, it is true, because of the first condition I mentioned forNATURAL JOIN
. However, we don't have to restrict that simply toNATURAL JOIN
s alone.INNER JOIN
s,OUTER JOIN
s etc could be anEQUI JOIN
too.
DecimalFormat df = new DecimalFormat(fmt);
df.setRoundingMode(RoundingMode.DOWN);
s = df.format(d);
Check available RoundingMode
and DecimalFormat
.
I was getting the same error but it's sorted now. In my case, I had columns with the heading "Key1", "Key2", and "Key3". I have changed the column names to something else and it's sorted.
It seems that these are reserved keywords.

Any of the below three options works for you:
echo[
echo(
echo.
For example:
@echo off
echo There will be a blank line below
echo[
echo Above line is blank
echo(
echo The above line is also blank.
echo.
echo The above line is also blank.
This can be done using the unique function in ufp.path module.
import ufp.path
ufp.path.unique('./test.ext')
if current path exists 'test.ext' file. ufp.path.unique function return './test (d1).ext'.
Perhaps an analogy will help understanding the difference:
<student id="JonathanSampson" class="Biology Calculus" />
<student id="MarySmith" class="Biology Networking" />
Student ID cards are distinct. No two students on campus will have the same student ID card. However, many students can and will share at least one Class with each other.
It's okay to put multiple students under one Class title, such as Biology. But it's never acceptable to put multiple students under one student ID.
When giving Rules over the school intercom system, you can give Rules to a Class:
"Tomorrow, all students are to wear a red shirt to Biology class."
.Biology {
color: red;
}
Or you can give rules to a Specific Student, by calling his unique ID:
"Jonathan Sampson is to wear a green shirt tomorrow."
#JonathanSampson {
color: green;
}
In this case, Jonathan Sampson is receiving two commands: one as a student in the Biology class, and another as a direct requirement. Because Jonathan was told directly, via the id attribute, to wear a green shirt, he will disregard the earlier request to wear a red shirt.
The more specific selectors win.
