Here's a more concise approach...
df['a_bsum'] = df.groupby('A')['B'].transform(sum)
df.sort(['a_bsum','C'], ascending=[True, False]).drop('a_bsum', axis=1)
The first line adds a column to the data frame with the groupwise sum. The second line performs the sort and then removes the extra column.
Result:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False
3 foo -1.072969 True
0 foo 1.624345 False
NOTE: sort
is deprecated, use sort_values
instead
I also had an issue with multiline strings in this scenario. @Iman's backtick(`) solution worked great in the modern browsers but caused an invalid character error in Internet Explorer. I had to use the following:
'@item.MultiLineString.Replace(Environment.NewLine, "<br />")'
Then I had to put the carriage returns back again in the js function. Had to use RegEx to handle multiple carriage returns.
// This will work for the following:
// "hello\nworld"
// "hello<br>world"
// "hello<br />world"
$("#MyTextArea").val(multiLineString.replace(/\n|<br\s*\/?>/gi, "\r"));
You cannot straightly query mongodb collections by date components like day or month. But its possible by using the special $where javascript expression
db.mydatabase.mycollection.find({$where : function() { return this.date.getMonth() == 11} })
or simply
db.mydatabase.mycollection.find({$where : 'return this.date.getMonth() == 11'})
(But i prefer the first one)
Check out the below shell commands to get the parts of date
>date = ISODate("2011-09-25T10:12:34Z")
> date.getYear()
111
> date.getMonth()
8
> date.getdate()
25
EDIT:
Use $where only if you have no other choice. It comes with the performance problems. Please check out the below comments by @kamaradclimber and @dcrosta. I will let this post open so the other folks get the facts about it.
and check out the link $where Clauses and Functions in Queries for more info
After some trial and error, I found that
$computername = $env:computername
works to get a computer name, but sending $computername
to a file via Add-Content doesn't work.
I also tried $computername.Value
.
Instead, if I use
$computername = get-content env:computername
I can send it to a text file using
$computername | Out-File $file
public function index()
{
if(!$this->isLogin())
return Redirect::to('login');
if(Request::ajax()) // This is check ajax request
{
return $JSON;
}
$data = array();
$data['records'] = $this->table->fetchAll();
$this->setLayout(compact('data'));
}
v4l support has been dropped in recent kernel versions (including the one shipped with Ubuntu 11.04).
EDIT: Your question is connected to a recent message that was sent to the OpenCV users group, which has instructions to compile OpenCV 2.2 in Ubuntu 11.04. Your approach is not ideal.
You can use [(ngModel)]
, but you'll need to update your value
to [value]
otherwise the value is evaluating as a string. It would look like this:
<label>This rule is true if:</label>
<label class="form-check-inline">
<input class="form-check-input" type="radio" name="mode" [value]="true" [(ngModel)]="rule.mode">
</label>
<label class="form-check-inline">
<input class="form-check-input" type="radio" name="mode" [value]="false" [(ngModel)]="rule.mode">
</label>
If rule.mode
is true, then that radio is selected. If it's false, then the other.
The difference really comes down to the value
. value="true"
really evaluates to the string 'true', whereas [value]="true"
evaluates to the boolean true.
A variant using Bat/Powershell (need .net framework):
replace.bat :
@echo off
call:DoReplace "Findstr" "replacestr" test.txt test1.txt
exit /b
:DoReplace
echo ^(Get-Content "%3"^) ^| ForEach-Object { $_ -replace %1, %2 } ^| Set-Content %4>Rep.ps1
Powershell.exe -executionpolicy ByPass -File Rep.ps1
if exist Rep.ps1 del Rep.ps1
echo Done

I used following commands from GoLang official repository, it installed GoLang version 1.6 on my Ubuntu 14.04
sudo add-apt-repository ppa:ubuntu-lxc/lxd-stable
sudo apt-get update
sudo apt-get install golang
Reference official GoLang Repo https://github.com/golang/go/wiki/Ubuntu it seems this ppa will always be updated in future.
If you will invoke the script with source
, you can use return <x>
where <x>
will be the script exit status (use a non-zero value for error or false). But if you invoke an executable script (i.e., directly with its filename), the return statement will result in a complain (error message "return: can only `return' from a function or sourced script").
If exit <x>
is used instead, when the script is invoked with source
, it will result in exiting the shell that started the script, but an executable script will just terminate, as expected.
To handle either case in the same script, you can use
return <x> 2> /dev/null || exit <x>
This will handle whichever invocation may be suitable. That is assuming you will use this statement at the script's top level. I would advise against directly exiting the script from within a function.
Note: <x>
is supposed to be just a number.
I cannot comment because of the 50pts threshhold, but I don't think that the answer provided in https://stackoverflow.com/a/537344/1341220 is correct. What you are actually describing is how you insert server certificates into the systems default truststore:
$JAVA_HOME/jre/lib/security/cacerts, password: changeit)
This works, indeed, but it means that you did not really specify a trust store local to your project, but rather accepted the certificate universially in your system.
You actually never use your own truststore that you defined here:
System.setProperty("javax.net.ssl.trustStore", "myTrustStore");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
Terminology : The difference between TRUE north and Magnetic North is known as "variation" not declination. The difference between what your compass reads and the magnetic heading is known as "deviation" and varies with heading. A compass swing identifies device errors and allows corrections to be applied if the device has correction built in. A magnetic compass will have a deviation card which describes the device error on any heading.
Declination : A term used in Astro navigation : Declination is like latitude. It reports how far a star is from the celestial equator. To find the declination of a star follow an hour circle "straight down" from the star to the celestial equator. The angle from the star to the celestial equator along the hour circle is the star's declination.
One more important difference: typedef
s cannot be forward declared. So for the typedef
option you must #include
the file containing the typedef
, meaning everything that #include
s your .h
also includes that file whether it directly needs it or not, and so on. It can definitely impact your build times on larger projects.
Without the typedef
, in some cases you can just add a forward declaration of struct Foo;
at the top of your .h
file, and only #include
the struct definition in your .cpp
file.
Just in case it may help somebody, you may also try this animator ViewPropertyAnimator as below
myView.animate().x(50f).y(100f);
myView.animate().translateX(pixelInScreen)
Note: This pixel is not relative to the view. This pixel is the pixel position in the screen.

There is a pairwise()
function example in the itertools
document:
from itertools import tee, izip
def pairwise(iterable):
"s -> (s0,s1), (s1,s2), (s2, s3), ..."
a, b = tee(iterable)
next(b, None)
return izip(a, b)
import pandas as pd
df = pd.DataFrame(['AA', 'BB', 'CC'], columns = ['value'])
for (i1, row1), (i2, row2) in pairwise(df.iterrows()):
print i1, i2, row1["value"], row2["value"]
Here is the output:
0 1 AA BB
1 2 BB CC
But, I think iter rows in a DataFrame
is slow, if you can explain what's the problem you want to solve, maybe I can suggest some better method.
Here is a more generic solution for any given weekday. Working demo on jsfiddle
var myIsoWeekDay = 2; // say our weeks start on tuesday, for monday you would type 1, etc.
var startOfPeriod = moment("2013-06-23T00:00:00"),
// how many days do we have to substract?
var daysToSubtract = moment(startOfPeriod).isoWeekday() >= myIsoWeekDay ?
moment(startOfPeriod).isoWeekday() - myIsoWeekDay :
7 + moment(startOfPeriod).isoWeekday() - myIsoWeekDay;
// subtract days from start of period
var begin = moment(startOfPeriod).subtract('d', daysToSubtract);
Using:
SELECT t.ctn_no
FROM YOUR_TABLE t
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1
...will show you the ctn_no
value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:
SELECT t.ctn_no
FROM YOUR_TABLE t
WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1
If you want to see the other column values associated with the duplicate, you'll want to use a self join:
SELECT x.*
FROM YOUR_TABLE x
JOIN (SELECT t.ctn_no
FROM YOUR_TABLE t
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no
Many distinctions have already been mentioned. Here is one more:
Running npm install
at the top of your source directory will run various scripts: prepublish
, preinstall
, install
, postinstall
. Depending on what these scripts do, a npm install
may do considerably more work than just installing dependencies.
I've just had a use case where prepublish
would call make
and the Makefile
was designed to fetch dependencies if the package.json
got updated. Calling npm install
from within the Makefile
would have lead to an infinite recursion, while calling npm update
worked just fine, installing all dependencies so that the build could proceed even if make
was called directly.
Use the Take(int n)
method:
var q = query.Take(10);
It's possible to "natively" select by value:
dropdownlist.select(1);
The question is what's the difference between
char *name
which points to a constant string literal, and
const char *cname
I.e. given
char *name = "foo";
and
const char *cname = "foo";
There is not much difference between the 2 and both can be seen as correct. Due to the long legacy of C code, the string literals have had a type of char[]
, not const char[]
, and there are lots of older code that likewise accept char *
instead of const char *
, even when they do not modify the arguments.
The principal difference of the 2 in general is that *cname
or cname[n]
will evaluate to lvalues of type const char
, whereas *name
or name[n]
will evaluate to lvalues of type char
, which are modifiable lvalues. A conforming compiler is required to produce a diagnostics message if target of the assignment is not a modifiable lvalue; it need not produce any warning on assignment to lvalues of type char
:
name[0] = 'x'; // no diagnostics *needed*
cname[0] = 'x'; // a conforming compiler *must* produce a diagnostic message
The compiler is not required to stop the compilation in either case; it is enough that it produces a warning for the assignment to cname[0]
. The resulting program is not a correct program. The behaviour of the construct is undefined. It may crash, or even worse, it might not crash, and might change the string literal in memory.
As @daniel-t points out in the comment: github.com/docker/docker/issues/2174 is about showing binding only to IPv6 in netstat
, but that is not an issue. As that github issues states:
When setting up the proxy, Docker requests the loopback address '127.0.0.1', Linux realises this is an address that exists in IPv6 (as ::0) and opens on both (but it is formally an IPv6 socket). When you run netstat it sees this and tells you it is an IPv6 - but it is still listening on IPv4. If you have played with your settings a little, you may have disabled this trick Linux does - by setting net.ipv6.bindv6only = 1.
In other words, just because you see it as IPv6 only, it is still able to communicate on IPv4 unless you have IPv6 set to only bind on IPv6 with the net.ipv6.bindv6only setting. To be clear, net.ipv6.bindv6only should be 0 - you can run sysctl net.ipv6.bindv6only
to verify.
You need to use the scrollTop
property.
document.getElementById('box').scrollTop
Always prefer Count
and Length
properties on a type over the extension method Count()
. The former is an O(1) for every type which contains them. The Count()
extension method has some type check optimizations that can cause it to run also in O(1) time but will degrade to O(N) if the underlying collection is not one of the few types it knows about.
I wanted 2 way conversion, and I wanted to use Python 3 format() support to be most pythonic. Maybe try datasize library module? https://pypi.org/project/datasize/
$ pip install -qqq datasize
$ python
...
>>> from datasize import DataSize
>>> 'My new {:GB} SSD really only stores {:.2GiB} of data.'.format(DataSize('750GB'),DataSize(DataSize('750GB') * 0.8))
'My new 750GB SSD really only stores 558.79GiB of data.'
Suppose I have Hashmap with key datatype as KeyDataType and value datatype as ValueDataType
HashMap<KeyDataType,ValueDataType> list;
Add all items you needed to it. Now you can retrive all hashmap keys to a list by.
KeyDataType[] mKeys;
mKeys=list.keySet().toArray(new KeyDataType[list.size()]);
So, now you got your all keys in an array mkeys[]
you can now retrieve any value by calling
list.get(mkeys[position]);
use "hh:mm a"
instead of "HH:mm a"
. Here hh
for 12 hour format and HH
for 24 hour format.
Live Demo
Take an example
<root>
<parent>
<child_one>Y</child_one>
<child_two>12</child_two>
</parent>
</root>
and design an xsd for that:
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="parent">
<xs:complexType>
<xs:sequence>
<xs:element name="child_one" type="xs:string" />
<xs:element name="child_two" type="xs:int" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
What isn't possible with XSD: would like to write it first as the list is very small
1) You can't validate a node/attribute using the value of another node/attribute.
2) This is a restriction : An element defined in XSD file must be defined with only one datatype. [in the above example, for <child_two>
appearing in another <parent>
node, datatype cannot be defined other than int.
3) You can't ignore the validation of elements and attributes, ie, if an element/attribute appears in XML, it must be well-defined in the corresponding XSD. Though usage of <xsd:any>
allows it, but it has got its own rules. Abiding which leads to the validation error. I had tried for a similar approach, and certainly wasn't successful, here is the Q&A
what are possible with XSD:
1) You can test the proper hierarchy of the XML nodes. [xsd defines which child should come under which parent, etc, abiding which will be counted as error, in above example, child_two cannot be the immediate child of root, but it is the child of "parent" tag which is in-turn a child of "root" node, there is a hierarchy..]
2) You can define Data type of the values of the nodes. [in above example child_two cannot have any-other data than number]
3) You can also define custom data_types, [example, for node <month>
, the possible data can be one of the 12 months.. so you need to define all the 12 months in a new data type writing all the 12 month names as enumeration values .. validation shows error if the input XML contains any-other value than these 12 values .. ]
4) You can put the restriction on the occurrence of the elements, using minOccurs and maxOccurs, the default values are 1 and 1.
.. and many more ...
The '\r'
character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.
From the old telnet specification (RFC 854) (page 11):
The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").
However, from the latest specification (RFC5198) (page 13):
...
In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.
LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).
So newline in Telnet should always be '\r\n'
but most implementations have either not been updated, or keeps the old '\n\r'
for backwards compatibility.
but during a soccer-match, or a concert what does it matter if you are a single minute behind the stream?
To some soccer fans, quite a bit. It has been remarked that delays of even a few seconds present in digital video streams due to encoding (or whatever) can be very annoying when, during high-profile events such as world cup matches, you can hear the cheers and groans from the guys next door (who are watching an undelyed analog program) before you get to see the game moves that caused them.
I think that to someone caring a lot about sports (and those are the biggest group of paying customers for digital TV, at least here in Germany), being a minute behind in a live video stream would be completely unacceptable (As in, they'd switch to your competitor where this doesn't happen).
Just use
File.Copy(filepath, "\\\\192.168.1.28\\Files");
A windows fileshare exposed via a UNC path is treated as part of the file system, and has nothing to do with the web.
The credentials used will be that of the ASP.NET worker process, or any impersonation you've enabled. If you can tweak those to get it right, this can be done.
You may run into problems because you are using the IP address instead of the server name (windows trust settings prevent leaving the domain - by using IP you are hiding any domain details). If at all possible, use the server name!
If this is not on the same windows domain, and you are trying to use a different domain account, you will need to specify the username as "[domain_or_machine]\[username]"
If you need to specify explicit credentials, you'll need to look into coding an impersonation solution.
If this error arises when manipulating a file that was just opened, check to see if you opened it in 'rb'
mode
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#suburb").blur(function() {
if ($(this).val() != '')
$("#post_code").attr("disabled", "disabled");
else
$("#post_code").removeAttr("disabled");
});
$("#post_code").blur(function() {
if ($(this).val() != '')
$("#suburb").attr("disabled", "disabled");
else
$("#suburb").removeAttr("disabled");
});
});
</script>
You'll also need to add a value attribute to the first option under your select element:
<option value=""></option>
gradle com.android.tools.build:gradle:2.2.0-alpha6
constraint layout dependency com.android.support.constraint:constraint-layout:1.0.0-alpha4
works for me
Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase
, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:
void swapCase(char *name);
or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.
I'll leave the discussion of the difference between Build Tools, Platform Tools, and Tools to others. From a practical standpoint, you only need to know the answer to your second question:
Answer: Use the most recent version.
For those using Android Studio with Gradle, the buildToolsVersion
has to be set in the build.gradle
(Module: app) file.
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
...
}
Open the Android SDK Manager.
The last item will show the most recent version.
Make sure it is installed and then write that number as the buildToolsVersion
in build.gradle
(Module: app).
A bit of a hack, but it works fine for me:
Integer id = 2;
String query = "SELECT * FROM table WHERE id = ?";
PreparedStatement statement = m_connection.prepareStatement( query );
statement.setObject( 1, value );
String statementText = statement.toString();
query = statementText.substring( statementText.indexOf( ": " ) + 2 );
from array import array
listA = list(range(0,50))
for item in listA:
print(item)
arrayA = array("i", listA)
for item in arrayA:
print(item)
In Oracle 12c, you can now specify the CURRVAL and NEXTVAL sequence pseudocolumns as default values for a column. Alternatively, you can use Identity columns; see:
E.g.,
CREATE SEQUENCE t1_seq;
CREATE TABLE t1 (
id NUMBER DEFAULT t1_seq.NEXTVAL,
description VARCHAR2(30)
);
When we return a value from Stored procedure without select statement. We need to use "ParameterDirection.ReturnValue" and "ExecuteScalar" command to get the value.
CREATE PROCEDURE IsEmailExists
@Email NVARCHAR(20)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF EXISTS(SELECT Email FROM Users where Email = @Email)
BEGIN
RETURN 0
END
ELSE
BEGIN
RETURN 1
END
END
in C#
GetOutputParaByCommand("IsEmailExists")
public int GetOutputParaByCommand(string Command)
{
object identity = 0;
try
{
mobj_SqlCommand.CommandText = Command;
SqlParameter SQP = new SqlParameter("returnVal", SqlDbType.Int);
SQP.Direction = ParameterDirection.ReturnValue;
mobj_SqlCommand.Parameters.Add(SQP);
mobj_SqlCommand.Connection = mobj_SqlConnection;
mobj_SqlCommand.ExecuteScalar();
identity = Convert.ToInt32(SQP.Value);
CloseConnection();
}
catch (Exception ex)
{
CloseConnection();
}
return Convert.ToInt32(identity);
}
We get the returned value of SP "IsEmailExists" using above c# function.
These are configurable variables in php.ini:
; with sane limits
xdebug.var_display_max_depth = 10
xdebug.var_display_max_children = 256
xdebug.var_display_max_data = 1024
; with no limits
; (maximum nesting is 1023)
xdebug.var_display_max_depth = -1
xdebug.var_display_max_children = -1
xdebug.var_display_max_data = -1
Of course, these may also be set at runtime via ini_set()
, useful if you don't want to modify php.ini and restart your web server but need to quickly inspect something more deeply.
ini_set('xdebug.var_display_max_depth', '10');
ini_set('xdebug.var_display_max_children', '256');
ini_set('xdebug.var_display_max_data', '1024');
Xdebug settings are explained in the official documentation.
If you just want to get the information of current directory, you can type:

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.
Based on Jon Skeet answer i've made a class that permits to do it easily at work:

Notice that i used Guava to make an ImmutableMap but actually you could use a normal map i think since the map is never returned...
Part of the problem here is that the strings usually used to represent timezones are not actually unique. "EST" only means "America/New_York" to people in North America. This is a limitation in the C time API, and the Python solution is… to add full tz features in some future version any day now, if anyone is willing to write the PEP.
You can format and parse a timezone as an offset, but that loses daylight savings/summer time information (e.g., you can't distinguish "America/Phoenix" from "America/Los_Angeles" in the summer). You can format a timezone as a 3-letter abbreviation, but you can't parse it back from that.
If you want something that's fuzzy and ambiguous but usually what you want, you need a third-party library like dateutil
.
If you want something that's actually unambiguous, just append the actual tz name to the local datetime string yourself, and split it back off on the other end:
d = datetime.datetime.now(pytz.timezone("America/New_York"))
dtz_string = d.strftime(fmt) + ' ' + "America/New_York"
d_string, tz_string = dtz_string.rsplit(' ', 1)
d2 = datetime.datetime.strptime(d_string, fmt)
tz2 = pytz.timezone(tz_string)
print dtz_string
print d2.strftime(fmt) + ' ' + tz_string
Or… halfway between those two, you're already using the pytz
library, which can parse (according to some arbitrary but well-defined disambiguation rules) formats like "EST". So, if you really want to, you can leave the %Z
in on the formatting side, then pull it off and parse it with pytz.timezone()
before passing the rest to strptime
.
I too got the same error, problem in my case is I included the column name in GROUP BY
clause and it caused this error. So removed the column from GROUP BY
clause and it worked!!!
I wrote a DateTextField component.

auto
is not a valid value for padding
property, the only thing you can do is take out padding: 0;
from the *
declaration, else simply assign padding
to respective property block.
If you remove padding: 0;
from * {}
than browser will apply default styles to your elements which will give you unexpected cross browser positioning offsets by few pixels, so it is better to assign padding: 0;
using *
and than if you want to override the padding, simply use another rule like
.container p {
padding: 5px;
}

Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError
). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError
.
Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).
If that's not enough, consider converting to a sqlite3
database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.
No, find() method is not a member of std::list
.
Instead, use std::find
from <algorithm>
std :: list < int > l;
std :: list < int > :: iterator pos;
l.push_back(1);
l.push_back(2);
l.push_back(3);
l.push_back(4);
l.push_back(5);
l.push_back(6);
int elem = 3;
pos = find(l.begin() , l.end() , elem);
if(pos != l.end() )
std :: cout << "Element is present. "<<std :: endl;
else
std :: cout << "Element is not present. "<<std :: endl;
This works in the note-taking Joplin:
<span style="color:red">text in red</span>
git revert HEAD -m 1
In the above code line. "Last argument represents"
1 - reverts one commits.
2 - reverts last two commits.
n - reverts last n commits.
You need to push after this command to take the effect on remote. You have other options like specifying the range of commits to revert. This is one of the option.
Later use git commit -am "COMMIT_MESSAGE"
then git push
or git push -f
Since you have master page and your control is in content place holder, Your control id will be generated different in client side. you need to do like...
var TestVar = document.getElementById('<%= txt_model_code.ClientID %>').value;
Javascript runs on client side and to get value you have to provide client id of your control
You did not add #
before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.
See documentation: http://api.jquery.com/category/selectors/
its your friend.
Try this:
It seems that id: $("#Shareitem").val()
is wrong if you want to pass the value of
<input type="hidden" name="id" value="" id="id">
you need to change this line:
id: $("#Shareitem").val()
by
id: $("#id").val()
All together:
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
$(document).ready(function(){
$("#Shareitem").click(function(e){
e.preventDefault();
$.ajax({type: "POST",
url: "/imball-reagens/public/shareitem",
data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
success:function(result){
$("#sharelink").html(result);
}});
});
});
</script>
You can use HashMap, where Key is your string and value - count.
Most simple way (assumed you want to remove the element)
<span id='close' onclick='this.parentNode.parentNode.parentNode.removeChild(this.parentNode.parentNode); return false;'>x</span>
Add this inside your div
, an example here.
You may also use something like this
window.onload = function(){
document.getElementById('close').onclick = function(){
this.parentNode.parentNode.parentNode
.removeChild(this.parentNode.parentNode);
return false;
};
};
Css for close button
#close {
float:right;
display:inline-block;
padding:2px 5px;
background:#ccc;
}
You may add a hover effect like
#close:hover {
float:right;
display:inline-block;
padding:2px 5px;
background:#ccc;
color:#fff;
}
Something like this one.
You have to overwrite the file. In C++:
#include <fstream>
std::ofstream("test.txt", std::ios::out).close();
For the GUI minded people, you can:
You are specifying .fixedbutton
in your CSS (a class) and specifying the id
on the element itself.
Change your CSS to the following, which will select the id
fixedbutton
#fixedbutton {
position: fixed;
bottom: 0px;
right: 0px;
}
Take a look at "SET ROLE" and "SET SESSION AUTHORIZATION".
Navigate to the jmeter/bin

jmeter -n -t <YourTestScript.jmx> -l <TestScriptsResults.jtl>
It is never possible. Constructor Overriding is never possible in Java.
This is because,
Constructor looks like a method but name should be as class name and no return value.
Overriding means what we have declared in Super class, that exactly we have to declare in Sub class it is called Overriding. Super class name and Sub class names are different.
If you trying to write Super class Constructor in Sub class, then Sub class will treat that as a method not constructor because name should not match with Sub class name. And it will give an compilation error that methods does not have return value. So we should declare as void, then only it will compile.
Have a look at the following code :
Class One
{
....
One() { // Super Class constructor
....
}
One(int a) { // Super Class Constructor Overloading
....
}
}
Class Two extends One
{
One() { // this is a method not constructor
..... // because name should not match with Class name
}
Two() { // sub class constructor
....
}
Two(int b) { // sub class constructor overloading
....
}
}
There are lots of answer already given for this problem. Though this issue can happens for any API version, so just see the error line and find out android api version from path and platform name and go to the android sdk manager and delete related system image from sdk manager.
Dynamically change the css properties of .fa-xxx icons:
<li class="nws">
<a href="#NewsModal" class="urgent" title="' + title + '" onclick=""><span class="label label-icon label-danger"><i class="fa fa-bolt"></i></span>'
</a>
</li>
<script>
$(document).ready(function(){
$('li.nws').on("focusin", function(){
$('.fa-bolt').addClass('lightning');
});
});
</script>
<style>
.lightning{ /*do something cool like shutter*/}
</style>
Change it to this:
var email = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
This is a regular expression literal that is passed the i
flag which means to be case insensitive.
Keep in mind that email address validation is hard (there is a 4 or 5 page regular expression at the end of Mastering Regular Expressions demonstrating this) and your expression certainly will not capture all valid e-mail addresses.
I would concatenate the old list and new list as streams and save the results to destination list. Works well in parallel, too.
I will use the example of accepted answer given by Stuart Marks:
List<String> destList = Arrays.asList("foo");
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");
destList = Stream.concat(destList.stream(), newList.stream()).parallel()
.collect(Collectors.toList());
System.out.println(destList);
//output: [foo, 0, 1, 2, 3, 4, 5]
Hope it helps.
I just tested the code at the bottom and it prints 16384
twice (I'm on Excel 2010) and the first row gets selected. Your problem seems to be somewhere else.
Have you tried to get rid of the selects:
Sheets("BOM").Rows(copyFromRow).Copy
With Sheets("Proposal")
.Paste Destination:=.Rows(copyToRow)
copyToRow = copyToRow + 1
Application.CutCopyMode = False
.Rows(copyToRow).Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
End With
Test code to get convinced that the problem does not seem to be what you think it is.
Sub test()
Dim r
Dim i As Long
i = 1
r = Rows(i & ":" & i)
Debug.Print UBound(r, 2)
r = Rows(i)
Debug.Print UBound(r, 2)
Rows(i).Select
End Sub
Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

When you say "called" I'm going to assume you mean an ID tag.
To make it cross-brower, I wouldn't suggest using the CSS3 []
, although it is an option. This being said, give each of your textboxes a class like "tb" and the radio button "rb".
Then:
#divContainer .tb { width: 150px }
#divContainer .rb { width: 20px }
This assumes you are using the same classes elsewhere, if not, this will suffice:
.tb { width: 150px }
.rb { width: 20px }
As @David mentioned, to access anything within the division itself:
#divContainer [element] { ... }
Where [element] is whatever HTML element you need.
If you just want to throw away everything in your working folder (eg the results of a failed or aborted merge) and revert to a clean previous commit, do a git reset --hard
.
You can make buttons borderless through code as well:
TypedValue value= new TypedValue();
getApplicationContext().getTheme().resolveAttribute(android.R.attr.selectableItemBackground, value, true);
myButton.setBackgroundResource(value.resourceId);
The problem is related to AppCompat library. With it, you have
xmlns:appname="http://schemas.android.com/apk/res-auto"
and possibly:
appname:showAsAction="never"
in menu.xml file.
Without the lib, you can only have:
android:showAsAction="never"
and my app works with menu both on Android 4.3 and 2.3.3.
You want to use DATEADD, using a negative duration. e.g.
DATEADD(minute, -15, '2000-01-01 08:30:00')
This is about the HTML parse mechanism.
The HTML parser will parse the HTML content from top to bottom. In your script logic,
jQuery('#datetimepicker')
will return an empty instance because the element has not loaded yet.
You can use
$(function(){ your code here });
or
$(document).ready(function(){ your code here });
to parse HTML element firstly, and then do your own script logics.
You can setup an interval to keep checking if the user has scrolled then do something accordingly.
Borrowing from the great John Resig in his article.
Example:
let didScroll = false;
window.onscroll = () => didScroll = true;
setInterval(() => {
if ( didScroll ) {
didScroll = false;
console.log('Someone scrolled me!')
}
}, 250);

For me, I found this at:

This is the default location for Windows 64-bit.
Also, try to recall some of your default locations when not presented with some suggestions.
I had an issue with the same thing. ChromeOptions is very weird because it's not integrated with the desiredcapabilities like you would think. I forget the exact details, but basically ChromeOptions will reset to default certain values based on whether you did or did not pass a desired capabilities dict.
I did the following monkey-patch that allows me to specify my own dict without worrying about the complications of ChromeOptions
change the following code in /selenium/webdriver/chrome/webdriver.py:
def __init__(self, executable_path="chromedriver", port=0,
chrome_options=None, service_args=None,
desired_capabilities=None, service_log_path=None, skip_capabilities_update=False):
"""
Creates a new instance of the chrome driver.
Starts the service and then creates new instance of chrome driver.
:Args:
- executable_path - path to the executable. If the default is used it assumes the executable is in the $PATH
- port - port you would like the service to run, if left as 0, a free port will be found.
- desired_capabilities: Dictionary object with non-browser specific
capabilities only, such as "proxy" or "loggingPref".
- chrome_options: this takes an instance of ChromeOptions
"""
if chrome_options is None:
options = Options()
else:
options = chrome_options
if skip_capabilities_update:
pass
elif desired_capabilities is not None:
desired_capabilities.update(options.to_capabilities())
else:
desired_capabilities = options.to_capabilities()
self.service = Service(executable_path, port=port,
service_args=service_args, log_path=service_log_path)
self.service.start()
try:
RemoteWebDriver.__init__(self,
command_executor=self.service.service_url,
desired_capabilities=desired_capabilities)
except:
self.quit()
raise
self._is_remote = False
all that changed was the "skip_capabilities_update" kwarg. Now I just do this to set my own dict:
capabilities = dict( DesiredCapabilities.CHROME )
if not "chromeOptions" in capabilities:
capabilities['chromeOptions'] = {
'args' : [],
'binary' : "",
'extensions' : [],
'prefs' : {}
}
capabilities['proxy'] = {
'httpProxy' : "%s:%i" %(proxy_address, proxy_port),
'ftpProxy' : "%s:%i" %(proxy_address, proxy_port),
'sslProxy' : "%s:%i" %(proxy_address, proxy_port),
'noProxy' : None,
'proxyType' : "MANUAL",
'class' : "org.openqa.selenium.Proxy",
'autodetect' : False
}
driver = webdriver.Chrome( executable_path="path_to_chrome", desired_capabilities=capabilities, skip_capabilities_update=True )
use res.json, ajax, and promises, with a nice twist of localStorage to use it anywhere, added with tokens for that rare arcade love. PS, you could use cookies, but cookies can bite on https.
webpage.js

headers: {
Authorization: 'Bearer ' + idToken
},
processData: false,
}).done(function (data) {
localStorage.setItem('name', data.name);
//or whatever you want done.
}).fail(function (jqXHR, textStatus) {
var msg = 'Unable to fetch protected resource';
msg += '<br>' + jqXHR.status + ' ' + jqXHR.responseText;
if (jqXHR.status === 401) {
msg += '<br>Your token may be expired'
}
displayError(msg);
});
server.js, using express()
app.get('/main',
passport.authenticate('oauth2-jwt-bearer', { session: false }),
function (req, res) {
getUserInfo(req) //get your information to use it.
.then(function (userinfo) { //return your promise
res.json({ "name": userinfo.Name});
//you can declare/return more vars in this res.json.
//res.cookie('name', name); //https trouble
})
.error(function (e) {console.log("Error handler " + e)})
.catch(function (e) {console.log("Catch handler " + e)});
});
Thanks for your replies. Here's what I did:
git gc
git gc --aggressive
git prune
That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.
You can't call free
on the pointers returned from strsep
. Those are not individually allocated strings, but just pointers into the string s
that you've already allocated. When you're done with s
altogether, you should free it, but you do not have to do that with the return values of strsep
.
Graphics Programming in Windows is difficult to fault.
/dev/tty
is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c
in the ls -l
output means.
man 4 tty
or man -s 4 tty
should give you more information, or you can read the man page online here.
Incidentally, pwd > /dev/tty
doesn't necessarily print to the shell's stdout (though it is the pwd
command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty
still refers to the terminal.
You can also read from /dev/tty
, which will normally read from the keyboard.

Check the help on select_vars. That gives you some extra ideas on how to work with this.
In your case:
iris %>% select(-one_of(drop.cols))
This one works fine for me :
theme.applyStyle(R.style.AppTheme, true)
Usage:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
//The call goes right after super.onCreate() and before setContentView()
theme.applyStyle(R.style.AppTheme, true)
setContentView(layoutId)
onViewCreated(savedInstanceState)
}
[EDIT: March 2016: thanks for the votes! Though really, this is not the best answer, I think the solutions based on withColumn
, withColumnRenamed
and cast
put forward by msemelman, Martin Senne and others are simpler and cleaner].
I think your approach is ok, recall that a Spark DataFrame
is an (immutable) RDD of Rows, so we're never really replacing a column, just creating new DataFrame
each time with a new schema.
Assuming you have an original df with the following schema:
scala> df.printSchema
root
|-- Year: string (nullable = true)
|-- Month: string (nullable = true)
|-- DayofMonth: string (nullable = true)
|-- DayOfWeek: string (nullable = true)
|-- DepDelay: string (nullable = true)
|-- Distance: string (nullable = true)
|-- CRSDepTime: string (nullable = true)
And some UDF's defined on one or several columns:
import org.apache.spark.sql.functions._
val toInt = udf[Int, String]( _.toInt)
val toDouble = udf[Double, String]( _.toDouble)
val toHour = udf((t: String) => "%04d".format(t.toInt).take(2).toInt )
val days_since_nearest_holidays = udf(
(year:String, month:String, dayOfMonth:String) => year.toInt + 27 + month.toInt-12
)
Changing column types or even building a new DataFrame from another can be written like this:
val featureDf = df
.withColumn("departureDelay", toDouble(df("DepDelay")))
.withColumn("departureHour", toHour(df("CRSDepTime")))
.withColumn("dayOfWeek", toInt(df("DayOfWeek")))
.withColumn("dayOfMonth", toInt(df("DayofMonth")))
.withColumn("month", toInt(df("Month")))
.withColumn("distance", toDouble(df("Distance")))
.withColumn("nearestHoliday", days_since_nearest_holidays(
df("Year"), df("Month"), df("DayofMonth"))
)
.select("departureDelay", "departureHour", "dayOfWeek", "dayOfMonth",
"month", "distance", "nearestHoliday")
which yields:
scala> df.printSchema
root
|-- departureDelay: double (nullable = true)
|-- departureHour: integer (nullable = true)
|-- dayOfWeek: integer (nullable = true)
|-- dayOfMonth: integer (nullable = true)
|-- month: integer (nullable = true)
|-- distance: double (nullable = true)
|-- nearestHoliday: integer (nullable = true)
This is pretty close to your own solution. Simply, keeping the type changes and other transformations as separate udf val
s make the code more readable and re-usable.
If you can use JSONObject library, you could just
JSONArray ja = new JSONArray("[{\"Date\":\"2012-1-4T00:00:00\",\"keywords\":null,\"NeededString\":\"this is the sample string I am needed for my project\",\"others\":\"not needed\"}]");
String result = ja.getJSONObject(0).getString("NeededString");
My solution here is to loop, just to avoid duplicate option
<select class="form-control" name="status" >
<?php $lists = ['Current', 'Win', 'Lose']; ?>
@foreach($lists as $list)
<option value={{$list}} {{(old('status') == $list?'selected':'')}} >{{$list}}</option>
@endforeach
</select>
How much data can be added in java.util.List in Java at the maximum?
This is very similar to Theoretical limit for number of keys (objects) that can be stored in a HashMap?
The documentation of java.util.List
does not explicitly documented any limit on the maximum number of elements. The documentation of List.toArray
however, states that ...
Return an array containing all of the elements in this list in proper sequence (from first to last element); would have trouble implementing certain methods faithfully, such as
... so strictly speaking it would not be possible to faithfully implement this method if the list had more than 231-1 = 2147483647 elements since that is the largest possible array.
Some will argue that the documentation of size()
...
Returns the number of elements in this list. If this list contains more than
Integer.MAX_VALUE
elements, returnsInteger.MAX_VALUE
.
...indicates that there is no upper limit, but this view leads to numerous inconsistencies. See this bug report.
Is there any default size an array list?
If you're referring to ArrayList
then I'd say that the default size is 0. The default capacity however (the number of elements you can insert, without forcing the list to reallocate memory) is 10. See the documentation of the default constructor.
The size limit of ArrayList
is Integer.MAX_VALUE
since it's backed by an ordinary array.
It can be done now with HTML5
See this post here HTML select form with option to enter custom value
<input type="text" list="cars" />
<datalist id="cars">
<option>Volvo</option>
<option>Saab</option>
<option>Mercedes</option>
<option>Audi</option>
</datalist>

Try with, as if if condition

public String myMethod()

Because the compiler doesn't know if any of those if blocks will ever be reached, so it's giving you an error.

The current object is explicitly passed to the method as the first parameter. self

The whole point of a workspace is to group a set of related projects together that usually make up an application. The workspace framework comes down to the eclipse.core.resources
plugin and it naturally by design makes sense.
Projects have natures, builders are attached to specific projects and as you change resources in one project you can see in real time compile or other issues in projects that are in the same workspace. So the strategy I suggest is have different workspaces for different projects you work on but without a workspace in eclipse there would be no concept of a collection of projects and configurations and after all it's an IDE tool.
If that does not make sense ask how Net Beans or Visual Studio addresses this? It's the same theme. Maven is a good example, checking out a group of related maven projects into a workspace lets you develop and see errors in real time. If not a workspace what else would you suggest? An RCP application can be a different beast depending on what its used for but in the true IDE sense I don't know what would be a better solution than a workspace or context of projects. Just my thoughts. - Duncan
TryParse is the best way for parse or validate in single line:

Short description:
I solved this problem straitforward - using pixel manipulation.
Here is graphical answer:
Here is code:
function textHeight (text, font) {
var fontDraw = document.createElement("canvas");
var height = 100;
var width = 100;
// here we expect that font size will be less canvas geometry
fontDraw.setAttribute("height", height);
fontDraw.setAttribute("width", width);
var ctx = fontDraw.getContext('2d');
// black is default
ctx.fillRect(0, 0, width, height);
ctx.textBaseline = 'top';
ctx.fillStyle = 'white';
ctx.font = font;
ctx.fillText(text/*'Eg'*/, 0, 0);
var pixels = ctx.getImageData(0, 0, width, height).data;
// row numbers where we first find letter end where it ends
var start = -1;
var end = -1;
for (var row = 0; row < height; row++) {
for (var column = 0; column < width; column++) {
var index = (row * width + column) * 4;
// if pixel is not white (background color)
if (pixels[index] == 0) {
// we havent met white (font color) pixel
// on the row and the letters was detected
if (column == width - 1 && start != -1) {
end = row;
row = height;
break;
}
continue;
}
else {
// we find top of letter
if (start == -1) {
start = row;
}
// ..letters body
break;
}
}
}
/*
document.body.appendChild(fontDraw);
fontDraw.style.pixelLeft = 400;
fontDraw.style.pixelTop = 400;
fontDraw.style.position = "absolute";
*/
return end - start;
}
you need to import the function so the program know what that is here is example:
import os
import pyttsx3
i had the same problem first then i import the function and it work so i would really recommend to try it
@skaffman nailed it down. They live each in its own context. However, I wouldn't consider using scriptlets as the solution. You'd like to avoid them. If all you want is to concatenate strings in EL and you discovered that the +
operator fails for strings in EL (which is correct), then just do:
<c:out value="abc${test}" />
Or if abc
is to obtained from another scoped variable named ${resp}
, then do:
<c:out value="${resp}${test}" />
If you have a hidden field like this
<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("VertragNr") %>'/>
Now you can use your value like this
$(this).parent().find('input[type=hidden]').val()
This approach worked for me using the Material Components library:
In styles.xml
:
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<!-- Your styles here -->
<item name="toolbarStyle">@style/AppTheme.Toolbar</item>
</style>
<style name="AppTheme.Toolbar" parent="Widget.MaterialComponents.Toolbar">
<item name="titleTextColor">@android:color/white</item>
</style>

I also had this problem recently. Working with a new client, trying to get a an old web forms app running from Visual Studio, with IISExpress using Windows Authentication. For me, the web.config was correctly configured
However, the IISExpress.config settings file had:
<windowsAuthentication enabled="false">
The user account the developer was logged in was very new, so unlikely it had been edited. Simple fix it turned out, change this to enabled=true and it all ran as it should then.
For Vue 3, change this :
const router = createRouter({

To this :

Above solutions do not appropriately round numbers. I use:
double dp(double val, int places){
double mod = pow(10.0, places);
return ((val * mod).round().toDouble() / mod);
}
If you are here to copy-paste code:
This is an example which removes node_modules
from history
git filter-branch --tree-filter "rm -rf node_modules" --prune-empty HEAD
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force
What git actually does:
The first line iterates through all references on the same tree (--tree-filter
) as HEAD (your current branch), running the command rm -rf node_modules
. This command deletes the node_modules folder (-r
, without -r
, rm
won't delete folders), with no prompt given to the user (-f
). The added --prune-empty
deletes useless (not changing anything) commits recursively.
The second line deletes the reference to that old branch.
The rest of the commands are relatively straightforward.
This is very short answer.
import urllib
urllib.urlretrieve("http://photogallery.sandesh.com/Picture.aspx?AlubumId=422040", "Abc.jpg")
Note that the downside of garbage-collecting your repository is that, well, the garbage gets collected. As we all know as computer users, files we consider garbage right now might turn out to be very valuable three days in the future. The fact that git keeps most of its debris around has saved my bacon several times – by browsing all the dangling commits, I have recovered much work that I had accidentally canned.
So don’t be too much of a neat freak in your private clones. There’s little need for it.
OTOH, the value of data recoverability is questionable for repos used mainly as remotes, eg. the place all the devs push to and/or pulled from. There, it might be sensible to kick off a GC run and a repacking frequently.

ByteArrayInputStream also does the trick:
InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) );
Then convert to reader:
InputStreamReader reader = new InputStreamReader(is);

Find a root of a function, using Broyden’s first Jacobian approximation.
This method is also known as “Broyden’s good method”.

I used the plugin Smooth Scroll, at http://plugins.jquery.com/smooth-scroll/. With this plugin all you need to include is a link to jQuery and to the plugin code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="javascript/smoothscroll.js"></script>
(the links need to have the class smoothScroll
to work).
Another feature of Smooth Scroll is that the ancor name is not displayed in the URL!

ANDROID_HOME
is usually a directory like .android
. Its where things like the Debug Key will be stored.
export ANDROID_HOME=~/.android
You can automate it for your login. Just add it to your .bash_profile
(below is from my OS X 10.8.5 machine):
$ cat ~/.bash_profile
# MacPorts Installer addition on 2012-07-19 at 20:21:05
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Android
export ANDROID_NDK_ROOT=/opt/android-ndk-r9
export ANDROID_SDK_ROOT=/opt/android-sdk
export JAVA_HOME=`/usr/libexec/java_home`
export ANDROID_HOME=~/.android
export PATH="$ANDROID_SDK_ROOT/tools/":"$ANDROID_SDK_ROOT/platform-tools/":"$PATH"
According to David Turner on the NDK Mailing List, both ANDROID_NDK_ROOT
and ANDROID_SDK_ROOT
need to be set because other tools depend on those values (see Recommended NDK Directory?).
After modifying ~/.bash_profile
, then perform the following (or logoff and back on):
source ~/.bash_profile
LocalDate.parse(
"23-Mar-2017" ,
DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US )
)
The Question and other Answers are now outdated, using troublesome old date-time classes that are now legacy, supplanted by the java.time classes.
You seem to be dealing with date-only values. So do not use a date-time class. Instead use LocalDate
. The LocalDate
class represents a date-only value without time-of-day and without time zone.
Specify a Locale
to determine (a) the human language for translation of name of day, name of month, and such, and (b) the cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.
Parse a string.
String input = "23-Mar-2017" ;
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MMM-uuuu" , Locale.US ) ;
LocalDate ld = LocalDate.parse( input , f );
Generate a string.
String output = ld.format( f );
If you were given numbers rather than text for the year, month, and day-of-month, use LocalDate.of
.
LocalDate ld = LocalDate.of( 2017 , 3 , 23 ); // ( year , month 1-12 , day-of-month )
See this code run live at IdeOne.com.
input: 23-Mar-2017
ld.toString(): 2017-03-23
output: 23-Mar-2017
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.
Using a JDBC driver compliant with JDBC 4.2 or later, you may exchange java.time objects directly with your database. No need for strings nor 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.
This works also:
string url = HttpContext.Request.Url.Authority;
if($('#user_inp').length > 0 && $('#user_inp').val() != '')
{
$('#user_inp').css({"font-size":"18px"});
$('#user_line').css({"background-color":"#4cae4c","transition":"0.5s","height":"2px"});
$('#username').css({"color":"#4cae4c","transition":"0.5s","font-size":"18px"});
}
Look at module fnmatch. That will do what you're trying to do.
import fnmatch
import os
for file in os.listdir('.'):
if fnmatch.fnmatch(file, '*.txt'):
print file
You could try this:
#include <stdio.h>
int main()
{
int i,j;
int my_array[3][3] ={10, 23, 42, 1, 654, 0, 40652, 22, 0};
for(i = 0; i < 3; i++)
{
for(j = 0; j < 3; j++)
{
printf("%d ", my_array[i][j]);
}
printf("\n");
}
return 0;
}
Check Screen Options (dropdown tab in the upper right hand corner of the page), and make sure there are sane settings for what to show on screen. All the column settings should be checked, and there should be a positive number of media items being shown on screen.
If that is ok, then check Settings ? Media and make sure that Uploading Files folder is set to wp-content/uploads
.
I believe these are the only settings that can be changed from the administrative screens.
You can use .filter()
method of the Array
object:
var filtered = workItems.filter(function(element) {
// Create an array using `.split()` method
var cats = element.category.split(' ');
// Filter the returned array based on specified filters
// If the length of the returned filtered array is equal to
// length of the filters array the element should be returned
return cats.filter(function(cat) {
return filtersArray.indexOf(cat) > -1;
}).length === filtersArray.length;
});
Some old browsers like IE8 doesn't support .filter()
method of the Array
object, if you are using jQuery you can use .filter()
method of jQuery object.
jQuery version:
var filtered = $(workItems).filter(function(i, element) {
var cats = element.category.split(' ');
return $(cats).filter(function(_, cat) {
return $.inArray(cat, filtersArray) > -1;
}).length === filtersArray.length;
});
Thank you @zest! Worked like a charm. Some things of note: Need to apply Intel's hotfix for the HAXM to deal with kernel panic issue: http://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager Also, note, if you have more than one abi, you need to uninstall one due to a bug in the latest version of the Android API (r19): https://code.google.com/p/android/issues/detail?id=66740 (remove armeabi-v7a in this case, since you want the x86 abi). Other than the 45-minutes it took me to resolve these, it was an very rewarding exercise in terms of the increased performance of the emulator.
It might have many possibilities I guess. In my case, it was due packages versions inbalance
I had
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.1"/>
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.3"/>
I just need it to downgrade the core Design package to 3.1.1 to match the upper core version
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.1"/>
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.1"/>
Then it worked fine
The best way in browsers that support it, is to send the file as a Blob, or using FormData if you want a multipart form. You do not need a FileReader for that. This is both simpler and more efficient than trying to read the data.
If you specifically want to send it as multipart/form-data
, you can use a FormData object:
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
var formData = new FormData();
// This should automatically set the file name and type.
formData.append("file", file);
// Sending FormData automatically sets the Content-Type header to multipart/form-data
xmlHttpRequest.send(formData);
You can also send the data directly, instead of using multipart/form-data
. See the documentation. Of course, this will need a server-side change as well.
// file is an instance of File, e.g. from a file input.
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
xmlHttpRequest.setRequestHeader("Content-Type", file.type);
// Send the binary data.
// Since a File is a Blob, we can send it directly.
xmlHttpRequest.send(file);
For browser support, see: http://caniuse.com/#feat=xhr2 (most browsers, including IE 10+).
Skip all of this. Download Microsoft FUZZY LOOKUP add in. Create tables using your columns. Create a new worksheet. INPUT tables into the tool. Click all corresponding columns check boxes. Use slider for exact matches. HIT go and wait for the magic.
My naive assumption was that the size of scroll pane will be determined automatically...
The only solution that actually worked for me was explicitly seeting bounds of JScrollPane:
import javax.swing.*;
public class MyFrame extends JFrame {
public MyFrame()
{
setBounds(100, 100, 491, 310);
getContentPane().setLayout(null);
JTextArea textField = new JTextArea();
textField.setEditable(false);
String str = "";
for (int i = 0; i < 50; ++i)
str += "Some text\n";
textField.setText(str);
JScrollPane scroll = new JScrollPane(textField);
scroll.setBounds(10, 11, 455, 249); // <-- THIS
getContentPane().add(scroll);
setLocationRelativeTo ( null );
}
}
Maybe it will help some future visitors :)

INSERT INTO ... ON DUPLICATE KEY UPDATE will only work for MYSQL, not for SQL Server.
for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE
Like this:
declare @Source table
(
name varchar(30),
age decimal(23,0)
)
insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);
MERGE beautiful AS Tg
using @source as Sc
on tg.namet=sc.name
when matched then update
set tg.age=sc.age
when not matched then
insert (name, age) VALUES
(SC.name, sc.age);
we can groupby the 'name' and 'month' columns, then call agg() functions of Panda’s DataFrame objects.
The aggregation functionality provided by the agg() function allows multiple statistics to be calculated per group in one calculation.
df.groupby(['name', 'month'], as_index = False).agg({'text': ' '.join})
Use lang attribut on the input. Locale on my web app fr_FR, lang="en_EN" on the input number and i can use indifferently a comma or a dot. Firefox always display a dot, Chrome display a comma. But both separtor are valid.
This supplemental answer shows the effect of changing the line spacing.
You can set the multiplier and/or extra spacing with
textView.setLineSpacing(float add, float mult)
Or you can get the values with
int lineHeight = textView.getLineHeight();
float add = tvSampleText.getLineSpacingExtra(); // API 16+
float mult = tvSampleText.getLineSpacingMultiplier(); // API 16+
where the formula is
lineHeight = fontMetricsLineHeight * mult + add
The default multiplier is 1
and the default extra spacing is 0
.
Since API 16 you can supply an activity options bundle when calling Context.startActivity(Intent, Bundle) or related methods. It is created via the ActivityOptions builder:
Intent myIntent = new Intent(context, MyActivity.class);
ActivityOptions options =
ActivityOptions.makeCustomAnimation(context, R.anim.fade_in, R.anim.fade_out);
context.startActivity(myIntent, options.toBundle());
Don't forget to check out the other methods of the ActivityOptions builder and the ActivityOptionsCompat if you are using the Support Library.
API 5+:
For apps targeting API level 5+ there is the Activities overridePendingTransition
method. It takes two resource IDs for the incoming and outgoing animations. An id of 0
will disable the animations. Call this immediately after the startActivity
call.
i.e.:
startActivity(new Intent(this, MyActivity.class));
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);
API 3+:
You can prevent the default animation (Slide in from the right) with the Intent.FLAG_ACTIVITY_NO_ANIMATION
flag in your intent.
i.e.:
Intent myIntent = new Intent(context, MyActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
context.startActivity(myIntent);
then in your Activity you simply have to specify your own animation.
This also works for the 1.5 API (Level 3).
If you're using express@~3.0.0 change the line below from your example:
app.use(express.staticProvider(__dirname + '/public'));
to something like this:
app.set("view options", {layout: false});
app.use(express.static(__dirname + '/public'));
I made it as described on express api page and it works like charm. With that setup you don't have to write additional code so it becomes easy enough to use for your micro production or testing.
Full code listed below:
var express = require('express');
var app = express.createServer();
app.set("view options", {layout: false});
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res) {
res.render('index.html');
});
app.listen(8080, '127.0.0.1')
List(1,2,3) :+ 4
Results in List[Int] = List(1, 2, 3, 4)
Note that this operation has a complexity of O(n). If you need this operation frequently, or for long lists, consider using another data type (e.g. a ListBuffer).
On Android >=6.0, We have to request permission runtime.
Step1: add in AndroidManifest.xml file
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Step2: Request permission.
int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);
if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_READ_PHONE_STATE);
} else {
//TODO
}
Step3: Handle callback when you request permission.
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case REQUEST_READ_PHONE_STATE:
if ((grantResults.length > 0) && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
//TODO
}
break;
default:
break;
}
}
Edit: Read official guide here Requesting Permissions at Run Time
You can also use PHP's error_reporting();
// Disable it all for current call
error_reporting(0);
If you want to ignore errors from one function only, you can prepend a @
symbol.
@any_function(); // Errors are ignored
For Xamarin.iOS developers, I found it from this document https://developer.xamarin.com/api/type/Foundation.NSAttributedString/
textField.AttributedPlaceholder = new NSAttributedString ("Hello, world",new UIStringAttributes () { ForegroundColor = UIColor.Red });
I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.
I self-signed my application, following this link self-sign and release application, It only took 5 minutes, then I emailed the signed-APK file to myself and downloaded it to SD-card and then installed it without any problem.
For some DLLs I found version info manually with objdump
in .rsrc. With objdump -s -j .rsrc zlib1.dll
:

The trim() method removes whitespace from both sides of a string.
To remove all the spaces from the string use .replace(/\s/g, "")
this.maintabinfo = this.inner_view_data.replace(/\s/g, "").toLowerCase();
You're asking it to parse the JSON text something
(not "something"
). That's invalid JSON, strings must be in double quotes.
If you want an equivalent to your first example:
var s = '"something"';
var result = JSON.parse(s);
Follow this method if problem comes when working with angular2+ projects
I was looking for a solution when i got this error, and it got me here. But this question seems to be specific but the error is not, its a generic error. This is a common error for angular developers dealing with Internet Explorer.
I had the same issue while working with angular 2+, and it got resolved just by few simple steps.
In Angular latest versions, there are come commented codes in the polyfills.ts shows all the polyfills required for the smooth running in Internet Explorer versions IE09,IE10 and IE11
/** IE9, IE10 and IE11 requires all of the following polyfills. **/
//import 'core-js/es6/symbol';
//import 'core-js/es6/object';
//import 'core-js/es6/function';
//import 'core-js/es6/parse-int';
//import 'core-js/es6/parse-float';
//import 'core-js/es6/number';
//import 'core-js/es6/math';
//import 'core-js/es6/string';
//import 'core-js/es6/date';
//import 'core-js/es6/array';
//import 'core-js/es6/regexp';
//import 'core-js/es6/map';
//import 'core-js/es6/weak-map';
//import 'core-js/es6/set';
Uncomment the codes and it would work perfectly in IE browsers
/** IE9, IE10 and IE11 requires all of the following polyfills. **/

But you might see a performance drop in IE browsers compared to others :(
The most popular answer is right but I think the code is uselessly complicated. With the same css, this jquery code is easier to understand I believe:
$('#myCarousel').carousel({
interval: 10000
})
$('.carousel .item').each(function() {
var item = $(this);
item.siblings().each(function(index) {
if (index < 4) {
$(this).children(':first-child').clone().appendTo(item);
}
});
});
There are basically three main methods of achieving administrator execution
privileges on Windows.
cmd.exe
python
executable (Not recommended)cmd.exe
as and adminSince in Windows there is no sudo
command you have to run the terminal (cmd.exe
) as an administrator to achieve to level of permissions equivalent to sudo
. You can do this two ways:
Manually
cmd.exe
in C:\Windows\system32
Run as Administrator
C:\Windows\system32
Via key shortcuts
alt
and ctrl
usually) + X
.Command Prompt (Admin)
By doing that you are running as Admin so this problem should not persist
python.exe
Properties
"C:\path_to\python.exe" C:\path_to\your_script.py"
Answer contributed by delphifirst in this question
python
executable (Not recommended)This is a possibility but I highly discourage you from doing so.
It just involves finding the python
executable and setting it to run as administrator every time. Can and probably will cause problems with things like file creation (they will be admin only) or possibly modules that require NOT being an admin to run.
Since I wrote my prior answer, I have formulated a new definition of the declarative property which is quoted below. I have also defined imperative programming as the dual property.
This definition is superior to the one I provided in my prior answer, because it is succinct and it is more general. But it may be more difficult to grok, because the implication of the incompleteness theorems applicable to programming and life in general are difficult for humans to wrap their mind around.
The quoted explanation of the definition discusses the role pure functional programming plays in declarative programming.
All exotic types of programming fit into the following taxonomy of declarative versus imperative, since the following definition claims they are duals.
Declarative vs. Imperative
The declarative property is weird, obtuse, and difficult to capture in a technically precise definition that remains general and not ambiguous, because it is a naive notion that we can declare the meaning (a.k.a semantics) of the program without incurring unintended side effects. There is an inherent tension between expression of meaning and avoidance of unintended effects, and this tension actually derives from the incompleteness theorems of programming and our universe.
It is oversimplification, technically imprecise, and often ambiguous to define declarative as “what to do” and imperative as “how to do”. An ambiguous case is the “what” is the “how” in a program that outputs a program— a compiler.
Evidently the unbounded recursion that makes a language Turing complete, is also analogously in the semantics— not only in the syntactical structure of evaluation (a.k.a. operational semantics). This is logically an example analogous to Gödel's theorem— “any complete system of axioms is also inconsistent”. Ponder the contradictory weirdness of that quote! It is also an example that demonstrates how the expression of semantics does not have a provable bound, thus we can't prove2 that a program (and analogously its semantics) halt a.k.a. the Halting theorem.
The incompleteness theorems derive from the fundamental nature of our universe, which as stated in the Second Law of Thermodynamics is “the entropy (a.k.a. the # of independent possibilities) is trending to maximum forever”. The coding and design of a program is never finished— it's alive!— because it attempts to address a real world need, and the semantics of the real world are always changing and trending to more possibilities. Humans never stop discovering new things (including errors in programs ;-).
To precisely and technically capture this aforementioned desired notion within this weird universe that has no edge (ponder that! there is no “outside” of our universe), requires a terse but deceptively-not-simple definition which will sound incorrect until it is explained deeply.
Definition:
The declarative property is where there can exist only one possible set of statements that can express each specific modular semantic.
The imperative property3 is the dual, where semantics are inconsistent under composition and/or can be expressed with variations of sets of statements.
This definition of declarative is distinctively local in semantic scope, meaning that it requires that a modular semantic maintain its consistent meaning regardless where and how it's instantiated and employed in global scope. Thus each declarative modular semantic should be intrinsically orthogonal to all possible others— and not an impossible (due to incompleteness theorems) global algorithm or model for witnessing consistency, which is also the point of “More Is Not Always Better” by Robert Harper, Professor of Computer Science at Carnegie Mellon University, one of the designers of Standard ML.
Examples of these modular declarative semantics include category theory functors e.g. the
Applicative
, nominal typing, namespaces, named fields, and w.r.t. to operational level of semantics then pure functional programming.Thus well designed declarative languages can more clearly express meaning, albeit with some loss of generality in what can be expressed, yet a gain in what can be expressed with intrinsic consistency.
An example of the aforementioned definition is the set of formulas in the cells of a spreadsheet program— which are not expected to give the same meaning when moved to different column and row cells, i.e. cell identifiers changed. The cell identifiers are part of and not superfluous to the intended meaning. So each spreadsheet result is unique w.r.t. to the cell identifiers in a set of formulas. The consistent modular semantic in this case is use of cell identifiers as the input and output of pure functions for cells formulas (see below).
Hyper Text Markup Language a.k.a. HTML— the language for static web pages— is an example of a highly (but not perfectly3) declarative language that (at least before HTML 5) had no capability to express dynamic behavior. HTML is perhaps the easiest language to learn. For dynamic behavior, an imperative scripting language such as JavaScript was usually combined with HTML. HTML without JavaScript fits the declarative definition because each nominal type (i.e. the tags) maintains its consistent meaning under composition within the rules of the syntax.
A competing definition for declarative is the commutative and idempotent properties of the semantic statements, i.e. that statements can be reordered and duplicated without changing the meaning. For example, statements assigning values to named fields can be reordered and duplicated without changed the meaning of the program, if those names are modular w.r.t. to any implied order. Names sometimes imply an order, e.g. cell identifiers include their column and row position— moving a total on spreadsheet changes its meaning. Otherwise, these properties implicitly require global consistency of semantics. It is generally impossible to design the semantics of statements so they remain consistent if randomly ordered or duplicated, because order and duplication are intrinsic to semantics. For example, the statements “Foo exists” (or construction) and “Foo does not exist” (and destruction). If one considers random inconsistency endemical of the intended semantics, then one accepts this definition as general enough for the declarative property. In essence this definition is vacuous as a generalized definition because it attempts to make consistency orthogonal to semantics, i.e. to defy the fact that the universe of semantics is dynamically unbounded and can't be captured in a global coherence paradigm.
Requiring the commutative and idempotent properties for the (structural evaluation order of the) lower-level operational semantics converts operational semantics to a declarative localized modular semantic, e.g. pure functional programming (including recursion instead of imperative loops). Then the operational order of the implementation details do not impact (i.e. spread globally into) the consistency of the higher-level semantics. For example, the order of evaluation of (and theoretically also the duplication of) the spreadsheet formulas doesn't matter because the outputs are not copied to the inputs until after all outputs have been computed, i.e. analogous to pure functions.
C, Java, C++, C#, PHP, and JavaScript aren't particularly declarative. Copute's syntax and Python's syntax are more declaratively coupled to intended results, i.e. consistent syntactical semantics that eliminate the extraneous so one can readily comprehend code after they've forgotten it. Copute and Haskell enforce determinism of the operational semantics and encourage “don't repeat yourself” (DRY), because they only allow the pure functional paradigm.
2 Even where we can prove the semantics of a program, e.g. with the language Coq, this is limited to the semantics that are expressed in the typing, and typing can never capture all of the semantics of a program— not even for languages that are not Turing complete, e.g. with HTML+CSS it is possible to express inconsistent combinations which thus have undefined semantics.
3 Many explanations incorrectly claim that only imperative programming has syntactically ordered statements. I clarified this confusion between imperative and functional programming. For example, the order of HTML statements does not reduce the consistency of their meaning.
Edit: I posted the following comment to Robert Harper's blog:
in functional programming ... the range of variation of a variable is a type
Depending on how one distinguishes functional from imperative programming, your ‘assignable’ in an imperative program also may have a type placing a bound on its variability.
The only non-muddled definition I currently appreciate for functional programming is a) functions as first-class objects and types, b) preference for recursion over loops, and/or c) pure functions— i.e. those functions which do not impact the desired semantics of the program when memoized (thus perfectly pure functional programming doesn't exist in a general purpose denotational semantics due to impacts of operational semantics, e.g. memory allocation).
The idempotent property of a pure function means the function call on its variables can be substituted by its value, which is not generally the case for the arguments of an imperative procedure. Pure functions seem to be declarative w.r.t. to the uncomposed state transitions between the input and result types.
But the composition of pure functions does not maintain any such consistency, because it is possible to model a side-effect (global state) imperative process in a pure functional programming language, e.g. Haskell's IOMonad and moreover it is entirely impossible to prevent doing such in any Turing complete pure functional programming language.
As I wrote in 2012 which seems to the similar consensus of comments in your recent blog, that declarative programming is an attempt to capture the notion that the intended semantics are never opaque. Examples of opaque semantics are dependence on order, dependence on erasure of higher-level semantics at the operational semantics layer (e.g. casts are not conversions and reified generics limit higher-level semantics), and dependence on variable values which can not be checked (proved correct) by the programming language.
Thus I have concluded that only non-Turing complete languages can be declarative.
Thus one unambiguous and distinct attribute of a declarative language could be that its output can be proven to obey some enumerable set of generative rules. For example, for any specific HTML program (ignoring differences in the ways interpreters diverge) that is not scripted (i.e. is not Turing complete) then its output variability can be enumerable. Or more succinctly an HTML program is a pure function of its variability. Ditto a spreadsheet program is a pure function of its input variables.
So it seems to me that declarative languages are the antithesis of unbounded recursion, i.e. per Gödel's second incompleteness theorem self-referential theorems can't be proven.
Lesie Lamport wrote a fairytale about how Euclid might have worked around Gödel's incompleteness theorems applied to math proofs in the programming language context by to congruence between types and logic (Curry-Howard correspondence, etc).
When having [FromBody]attribute, the string sent should not be a raw string, but rather a JSON string as it includes the wrapping quotes:
"test"
Similar answer string value is Empty when using FromBody in asp.net web api
Now you can try something like:
Instant starts = Instant.now();
Thread.sleep(10);
Instant ends = Instant.now();
System.out.println(Duration.between(starts, ends));
Output is in ISO 8601.
You can do this in Javascript
.
var time = new Date();
console.log(time.getHours() + ":" + time.getMinutes() + ":" + time.getSeconds());
At present it returns 15:5:18
. Note that if any of the values are less than 10, they will display using only one digit, not two.
Check this in JSFiddle
Updates:
For prefixed 0's try
var time = new Date();
console.log(
("0" + time.getHours()).slice(-2) + ":" +
("0" + time.getMinutes()).slice(-2) + ":" +
("0" + time.getSeconds()).slice(-2));
Simple solution
Hit below commend only to fix this error
npm install --save-dev @angular-devkit/build-angular
Add a 'New Swift File'-> AppDelegateEx.swift
add an extension to AppDelegate
import UIKit
extension AppDelegate {
class func isIPhone5 () -> Bool{
return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 568.0
}
class func isIPhone6 () -> Bool {
return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 667.0
}
class func isIPhone6Plus () -> Bool {
return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 736.0
}
}
usage:
if AppDelegate.isIPhone5() {
collectionViewTopConstraint.constant = 2
}else if AppDelegate.isIPhone6() {
collectionViewTopConstraint.constant = 20
}
I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jquery imports (one of them was primefaces's query) which caused conflicts to upload files.
Use
$(document).on("click", "#btn_a", function(){
alert ('button clicked');
});
to add the listener for the dynamically created button.
alert($("#btn_a").val());
will give you the value of the button
You can use Element.scrollIntoView()
method as was mentioned above. If you leave it with no parameters inside you will have an instant ugly scroll. To prevent that you can add this parameter - behavior:"smooth"
.
Example:
document.getElementById('scroll-here-plz').scrollIntoView({behavior: "smooth", block: "start", inline: "nearest"});
Just replace scroll-here-plz
with your div
or element on a website. And if you see your element at the bottom of your window or the position is not what you would have expected, play with parameter block: ""
. You can use block: "start"
, block: "end"
or block: "center"
.
Remember: Always use parameters inside an object {}.
If you would still have problems, go to https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView
There is detailed documentation for this method.
String blah = "HellO";
int count = 0;
for (char c : blah.toCharArray()) {
count++;
}
System.out.println("blah's length: " + count);
If you use
<select [ngModel]="object">
<option *ngFor="let object of objects" [ngValue]="object">{{object.name}}</option>
</select>
You need to set the property object
in you components class to the item from objects
that you want to have pre-selected.
class MyComponent {
object;
objects = [{name: 'a'}, {name: 'b'}, {name: 'c'}];
constructor() {
this.object = this.objects[1];
}
}
Mac users just need to run the following code on terminal
brew switch python 3.x.x
3.x.x should be the new python version.
This will update all the system links.

Okay, little late to the game, but none of these solutions quite did what I was trying to do. These solutions have a couple problems
I wanted a ListView with the grouping headers, and each ListViewItem should just be 'informational' without selection or hover over, but the ListViewItem has a button in it that I want to be click-able and have hover-over.
So, really what I want is the ListViewItem to not be a ListViewItem at all, So, I over rode the ListViewItem's ControlTemplate and just made it a simple ContentControl.
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ContentControl Content="{Binding Content, RelativeSource={RelativeSource TemplatedParent}}"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
Try this:
$("#dp3").on("dp.change", function(e) {
alert('hey');
});
The HTML5 spec says that the type
attribute is purely advisory and explains in detail how browsers should act if it's omitted (too much to quote here). It doesn't explicitly say that an omitted type attribute is either valid or invalid, but you can safely omit it knowing that browsers will still react as you expect.
You can just use
datetime.date.today()
It's light and returns exactly what you want.
There's no need for a parent POM.
You can omit the distributionManagement part entirely in your poms and set it either on your build server or in settings.xml.
To do it on the build server, just pass to the mvn
command:
-DaltSnapshotDeploymentRepository=snapshots::default::https://YOUR_NEXUS_URL/snapshots
-DaltReleaseDeploymentRepository=releases::default::https://YOUR_NEXUS_URL/releases
See https://maven.apache.org/plugins/maven-deploy-plugin/deploy-mojo.html for details which options can be set.
It's also possible to set this in your settings.xml
.
Just create a profile there which is enabled and contains the property.
Example settings.xml:
<settings>
[...]
<profiles>
<profile>
<id>nexus</id>
<properties>
<altSnapshotDeploymentRepository>snapshots::default::https://YOUR_NEXUS_URL/snapshots</altSnapshotDeploymentRepository>
<altReleaseDeploymentRepository>releases::default::https://YOUR_NEXUS_URL/releases</altReleaseDeploymentRepository>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
Make sure that credentials for "snapshots" and "releases" are in the <servers>
section of your settings.xml
The properties altSnapshotDeploymentRepository and altReleaseDeploymentRepository are introduced with maven-deploy-plugin version 2.8. Older versions will fail with the error message
Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter
To fix this, you can enforce a newer version of the plug-in:
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-deploy-plugin</artifactId>
<version>2.8</version>
</plugin>
</plugins>
</pluginManagement>
</build>
Add
android:screenOrientation="portrait"
or
android:screenOrientation="landscape"
to the <activity>
element/s in
the manifest and you're done.
It is possible that your compiler and the resources installed around it were somehow incomplete. I recommend re-installing your compiler: it should work after that.
map
seems like the right tool for the job to me.
my_list = ['foo', 'fob', 'faz', 'funk']
string = 'bar'
list2 = list(map(lambda orig_string: orig_string + string, my_list))
See this section on functional programming tools for more examples of map
.
Hey If you want to print selected area or div ,Try This.
<style type="text/css">
@media print
{
body * { visibility: hidden; }
.div2 * { visibility: visible; }
.div2 { position: absolute; top: 40px; left: 30px; }
}
</style>
Hope it helps you
What about this:
string tabs = new String('\t', n);
Where n
is the number of times you want to repeat the string.
Or better:
static string Tabs(int n)
{
return new String('\t', n);
}
I found the solution to a similar problem. I am using Gradle 1.11 (as April, 2014). The project name can be changed directly in settings.gradle
file as following:
rootProject.name='YourNewName'
This takes care of uploading to repository (Artifactory w/ its plugin for me) with the correct artifactId.
Suppose you have mulitple record for same date or leave_type but different id and you want the maximum no of id for same date or leave_type as i also sucked with this issue, so Yes you can do it with the following query:
select * from tabel_name where employee_no='123' and id=(
select max(id) from table_name where employee_no='123' and leave_type='5'
)
Can't you do this with just one heap? Update: no. See the comment.
Invariant: After reading 2*n
inputs, the min-heap holds the n
largest of them.
Loop: Read 2 inputs. Add them both to the heap, and remove the heap's min. This reestablishes the invariant.
So when 2n
inputs have been read, the heap's min is the nth largest. There'll need to be a little extra complication to average the two elements around the median position and to handle queries after an odd number of inputs.
Read this https://docs.djangoproject.com/en/dev/howto/static-files/:
For local development, if you are using runserver or adding staticfiles_urlpatterns to your URLconf, you’re done with the setup – your static files will automatically be served at the default (for newly created projects) STATIC_URL of /static/.
And try:
~/tmp$ django-admin.py startproject myprj
~/tmp$ cd myprj/
~/tmp/myprj$ chmod a+x manage.py

Then add 'myapp'
to INSTALLED_APPS
(myprj/settings.py
).
~/tmp/myprj$ cd myapp/
~/tmp/myprj/myapp$ mkdir static
~/tmp/myprj/myapp$ echo 'alert("hello!");' > static/hello.js
~/tmp/myprj/myapp$ mkdir templates
~/tmp/myprj/myapp$ echo '<script src="{{ STATIC_URL }}hello.js"></script>' > templates/hello.html
Edit myprj/urls.py
:
from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView
class HelloView(TemplateView):
template_name = "hello.html"
urlpatterns = patterns('',
url(r'^$', HelloView.as_view(), name='hello'),

Above code works fine for all !!! And it will also prevent inserting more than 2 decimal points. And if you don't need this just remove\d{0,2} or if need more limited decimal point just change number 2
replace it with index of the array.
array[index] = new_value;
I had been using Ladislav Mrnka's answer to successfully retrieve Ids when using the Entity Framework however I am posting here because I had been miss-using it (i.e. using it where it wasn't required) and thought I would post my findings here in-case people are looking to "solve" the problem I had.
Consider an Order object that has foreign key relationship with Customer. When I added a new customer and a new order at the same time I was doing something like this;
var customer = new Customer(); //no Id yet;
var order = new Order(); //requires Customer.Id to link it to customer;
context.Customers.Add(customer);
context.SaveChanges();//this generates the Id for customer
order.CustomerId = customer.Id;//finally I can set the Id
However in my case this was not required because I had a foreign key relationship between customer.Id and order.CustomerId
All I had to do was this;
var customer = new Customer(); //no Id yet;
var order = new Order{Customer = customer};
context.Orders.Add(order);
context.SaveChanges();//adds customer.Id to customer and the correct CustomerId to order
Now when I save the changes the id that is generated for customer is also added to order. I've no need for the additional steps
I'm aware this doesn't answer the original question but thought it might help developers who are new to EF from over-using the top-voted answer for something that may not be required.
This also means that updates complete in a single transaction, potentially avoiding orphin data (either all updates complete, or none do).
Suppose you need a car as we all know their are several A class manufacturer like MERCEDES, BMW , AUDI etc.
Now in above statement CAR(is a specification) as every car have common features like thing with 4 wheels and can be driven on road is car...so its like JPA. And MERCEDES, BMW , AUDI etc are just using common car feature and adding functionality according to their customer base so they are implementing the car specification like hibernate , iBATIS etc.
So by this common features goes to jpa and hibernate is just an implementation according to their jboss need.
JPA includes some basic properties so in future if you want to change hibernate to any other implementation you can easily switch without much headache and for those basic properties includes JPA annotations which can work for any implementation technology, JPQL queries.
So mainly we implement hibernate with JPA type technology just for in case we want to switch our implementation according to client need plus you will write less code as some common features are involved in JPA. If someone still not clear then you can comment as i m new on stack overflow.
I had this issue as well, and was tripped up for a while on it. I wanted to display 0.00 as 0 and otherwise keep the decimal point. The following didn't work:
CASE WHEN Amount= 0 THEN CONVERT(VARCHAR(30), Amount, 1) ELSE Amount END
Because the resulting column was forced to be a MONEY column. To resolve it, the following worked
CASE WHEN Amount= 0 THEN CONVERT(VARCHAR(30), '0', 1) ELSE CONVERT (VARCHAR(30), Amount, 1) END
This mattered because my final destination column was a VARCHAR(30), and the consumers of that column would error out if an amount was '0.00' instead of '0'.
You could use Mockito. I am not sure with PostConstruct
specifically, but this generally works:
// Create a mock of Resource to change its behaviour for testing
@Mock
private Resource resource;
// Testing instance, mocked `resource` should be injected here
@InjectMocks
@Resource
private TestedClass testedClass;
@Before
public void setUp() throws Exception {
// Initialize mocks created above
MockitoAnnotations.initMocks(this);
// Change behaviour of `resource`
when(resource.getSomething()).thenReturn("Foo");
}
Say the other guy created bar on top of foo, but you created baz in the meantime and then merged, giving a history of
$ git lola * 2582152 (HEAD, master) Merge branch 'otherguy' |\ | * c7256de (otherguy) bar * | b7e7176 baz |/ * 9968f79 foo
Note: git lola is a non-standard but useful alias.
No dice with git revert
:
$ git revert HEAD fatal: Commit 2582152... is a merge but no -m option was given.
Charles Bailey gave an excellent answer as usual. Using git revert
as in
$ git revert --no-edit -m 1 HEAD [master e900aad] Revert "Merge branch 'otherguy'" 0 files changed, 0 insertions(+), 0 deletions(-) delete mode 100644 bar
effectively deletes bar
and produces a history of
$ git lola * e900aad (HEAD, master) Revert "Merge branch 'otherguy'" * 2582152 Merge branch 'otherguy' |\ | * c7256de (otherguy) bar * | b7e7176 baz |/ * 9968f79 foo
But I suspect you want to throw away the merge commit:
$ git reset --hard HEAD^ HEAD is now at b7e7176 baz $ git lola * b7e7176 (HEAD, master) baz | * c7256de (otherguy) bar |/ * 9968f79 foo
As documented in the git rev-parse
manual
<rev>^
, e.g. HEAD^,v1.5.1^0
A suffix^
to a revision parameter means the first parent of that commit object.^<n>
means the n-th parent (i.e.<rev>^
is equivalent to<rev>^1
). As a special rule,<rev>^0
means the commit itself and is used when<rev>
is the object name of a tag object that refers to a commit object.
so before invoking git reset
, HEAD^
(or HEAD^1
) was b7e7176 and HEAD^2
was c7256de, i.e., respectively the first and second parents of the merge commit.
Be careful with git reset --hard
because it can destroy work.
Please check once the database selected are not because some times database is not selected
Check
mysql_select_db('database name ')or DIE('Database name is not available!');
before MySQL query and then go to next step

In your Terminal run ipython:

ROUTER LINK DIRECTIVE:
[routerLink]="link" //when u pass URL value from COMPONENT file

I usually store phone numbers as a BIGINT in E164 format.
E164 never start with a 0, with the first few digits being the country code.
+441234567890
+44 (0)1234 567890
01234 567890
etc. would be stored as 441234567890
.
Just wrap the button label in an extra span and add class="align-middle"
to both (the icon and the label). This will center your icon with text vertical.
<button id="edit-listing-form-house_Continue"
class="btn btn-large btn-primary"
style=""
value=""
name="Continue"
type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>
I encountered the same problem whilst trying to get Shinken 2.0.3 to fire up on Ubuntu. Eventually I did a full uninstall then reinstalled Shinken with pip -v
. As it cleaned up, it mentioned:
Warning: missing python-pycurl lib, you MUST install it before launch the shinken daemons
Installed that with apt-get
, and all the brokers fired up as expected :-)
If your app targets Android N (7.0) and above, you should not use the answers above (of the "Uri.fromFile" method), because it won't work for you.
Instead, you should use a ContentProvider.
For example, if your image file is in external folder, you can use this (similar to the code I've made here) :
File file = ...;
final Intent intent = new Intent(Intent.ACTION_VIEW)//
.setDataAndType(VERSION.SDK_INT >= VERSION_CODES.N ?
FileProvider.getUriForFile(this,getPackageName() + ".provider", file) : Uri.fromFile(file),
"image/*").addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
manifest:
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
res/xml/provider_paths.xml :
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!--<external-path name="external_files" path="."/>-->
<external-path
name="files_root"
path="Android/data/${applicationId}"/>
<external-path
name="external_storage_root"
path="."/>
</paths>
If your image is in the private path of the app, you should create your own ContentProvider, as I've created "OpenFileProvider" on the link.
