For Python 3.7 or later,(2018-10-10), I have to combine both @Alejandro BR and SMNALLY's answer, coz @Alejandro forget to define wincl.
import os, os.path
import win32com.client
if os.path.exists('C:/Users/jz/Desktop/test.xlsm'):
excel_macro = win32com.client.DispatchEx("Excel.Application") # DispatchEx is required in the newest versions of Python.
excel_path = os.path.expanduser('C:/Users/jz/Desktop/test.xlsm')
workbook = excel_macro.Workbooks.Open(Filename = excel_path, ReadOnly =1)
excel_macro.Application.Run("test.xlsm!Module1.Macro1") # update Module1 with your module, Macro1 with your macro
workbook.Save()
excel_macro.Application.Quit()
del excel_macro
Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator
And another link here
AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).
This is just because the application is built in non unicode language fonts and you are running the system on unicode fonts. change your default non unicode fonts to arabic by going in regional settings advanced tab in control panel. That will solve your problem.
Try echo_read_request_body.
"echo_read_request_body ... Explicitly reads request body so that the $request_body variable will always have non-empty values (unless the body is so big that it has been saved by Nginx to a local temporary file)."
location /log {
log_format postdata $request_body;
access_log /mnt/logs/nginx/my_tracking.access.log postdata;
echo_read_request_body;
}
I believe that if you download the offline ISO image file, and use that to install Visual Studio Express, you won't have to register.
Go here and find the link that says "All - Offline Install ISO image file". Click on it to expand it, select your language, and then click "Download".
Otherwise, it's possible that online registration is simply down for a while, as the error message indicates. You have 30 days before it expires, so give it a few days before starting to panic.
I had the same "TypeError: an integer is required" error message when attempting to write. Thanks, the .encode() solved it for me. I'm running python 3.4 on a Dell D530 running 32 bit Windows XP Pro.
I'm omitting the com port settings here:
>>>import serial
>>>ser = serial.Serial(5)
>>>ser.close()
>>>ser.open()
>>>ser.write("1".encode())
1
>>>
The only option I can think of is using width:100%
. If you want to have a padding on the input field too, than just place a container label
around it, move the formatting to that label instead, while also specify the padding to the label. Input fields are rigid.
This code would help:
int [] a={1,2,3,4,5,6,7};
for(int i=a.length-1;i>=0;i--)
System.out.println(a[i]);
Use LinkedList
instead. Than, you can create an array if necessary.
I needed C++ implementation working on std::string. None of answers satisfied my needs, I needed simple two-function solution for encoding and decoding, but I was too lazy to write my own code, so I found this:

Minimal runnable example
For this to make sense, you have to understand the basics of paging: How does x86 paging work? and in particular that the OS can allocate virtual memory via page tables / its internal memory book keeping (VSZ virtual memory) before it actually has a backing storage on RAM or disk (RSS resident memory).
Now to observe this in action, let's create a program that:
mmap

Exit status:

which by the 128 + signal number rule means we got signal number 9
, which man 7 signal
says is SIGKILL, which is sent by the Linux out-of-memory killer.
Output interpretation:
printf '0x%X\n' 0x40009A4 KiB ~= 64GiB
(ps
values are in KiB) after the mmap.extra_memory_committed 0
, which means we haven't yet touched any pages. RSS is a small 1648 KiB
which has been allocated for normal program startup like text area, globals, etc.8388608 KiB == 8GiB
worth of pages. As a result, RSS increased by exactly 8GIB to 8390256 KiB == 8388608 KiB + 1648 KiB

OOM killer logs
Our dmesg
commands have shown the OOM killer logs.
An exact interpretation of those has been asked at:
The very first line of the log was:
[ 7283.479087] mongod invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0
So we see that interestingly it was the MongoDB daemon that always runs in my laptop on the background that first triggered the OOM killer, presumably when the poor thing was trying to allocate some memory.
However, the OOM killer does not necessarily kill the one who awoke it.
After the invocation, the kernel prints a table or processes including the oom_score
:
[ 7283.479292] [ pid ] uid tgid total_vm rss pgtables_bytes swapents oom_score_adj name
[ 7283.479303] [ 496] 0 496 16126 6 172032 484 0 systemd-journal
[ 7283.479306] [ 505] 0 505 1309 0 45056 52 0 blkmapd
[ 7283.479309] [ 513] 0 513 19757 0 57344 55 0 lvmetad
[ 7283.479312] [ 516] 0 516 4681 1 61440 444 -1000 systemd-udevd
and further ahead we see that our own little main.out
actually got killed on the previous invocation:
[ 7283.479871] Out of memory: Kill process 15665 (main.out) score 865 or sacrifice child
[ 7283.479879] Killed process 15665 (main.out) total-vm:67111332kB, anon-rss:92kB, file-rss:4kB, shmem-rss:30080832kB
[ 7283.479951] oom_reaper: reaped process 15665 (main.out), now anon-rss:0kB, file-rss:0kB, shmem-rss:30080832kB
This log mentions the score 865
which that process had, presumably the highest (worst) OOM killer score as mentioned at: https://unix.stackexchange.com/questions/153585/how-does-the-oom-killer-decide-which-process-to-kill-first
Also interestingly, everything apparently happened so fast that before the freed memory was accounted, the oom
was awoken again by the DeadlineMonitor
process:
[ 7283.481043] DeadlineMonitor invoked oom-killer: gfp_mask=0x6200ca(GFP_HIGHUSER_MOVABLE), order=0, oom_score_adj=0
and this time that killed some Chromium process, which is usually my computers normal memory hog:
[ 7283.481773] Out of memory: Kill process 11786 (chromium-browse) score 306 or sacrifice child
[ 7283.481833] Killed process 11786 (chromium-browse) total-vm:1813576kB, anon-rss:208804kB, file-rss:0kB, shmem-rss:8380kB
[ 7283.497847] oom_reaper: reaped process 11786 (chromium-browse), now anon-rss:0kB, file-rss:0kB, shmem-rss:8044kB
Tested in Ubuntu 19.04, Linux kernel 5.0.0.
You could just do it like this
$query_select = "SELECT * FROM shouts ORDER BY id DESC LIMIT 8;";
$result_select = mysql_query($query_select) or die(mysql_error());
foreach($result_select as $row){
$ename = stripslashes($row['name']);
$eemail = stripcslashes($row['email']);
$epost = stripslashes($row['post']);
$eid = $row['id'];
$grav_url = "http://www.gravatar.com/avatar.php?gravatar_id=".md5(strtolower($eemail))."&size=70";
echo ('<img src = "' . $grav_url . '" alt="Gravatar">'.'<br/>');
echo $eid . '<br/>';
echo $ename . '<br/>';
echo $eemail . '<br/>';
echo $epost . '<br/><br/><br/><br/>';
}
Here is another way to express the object property.
foreach ($obj as $key=>$value) {
echo "$key => $obj[$key]\n";
}
When doing this I found it easiest to:
In a specific case where your epoch seconds timestamp comes from SQL or is related to SQL somehow, you can obtain it like this:
long startDateLong = <...>
LocalDate theDate = new java.sql.Date(startDateLong).toLocalDate();
Look at SignalR Tests for the feature.
Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.
The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.
Adding <validation validateIntegratedModeConfiguration="false"/>
addresses the symptom, but is not appropriate for all circumstances. Having ran around this issue a few times, I hope to help others not only overcome the problem but understand it. (Which becomes more and more important as IIS 6 fades into myth and rumor.)
Background:
This issue and the confusion surrounding it started with the introduction of ASP.NET 2.0 and IIS 7. IIS 6 had and continues to have only one pipeline mode, and it is equivalent to what IIS 7+ calls "Classic" mode. The second, newer, and recommended pipeline mode for all applications running on IIS 7+ is called "Integrated" mode.
So, what's the difference? The key difference is how ASP.NET interacts with IIS.
Classic mode is limited to an ASP.NET pipeline that cannot interact with the IIS pipeline. Essentially a request comes in and if IIS 6/Classic has been told, through server configuration, that ASP.NET can handle it then IIS hands off the request to ASP.NET and moves on. The significance of this can be gleaned from an example. If I were to authorize access to static image files, I would not be able to do it with an ASP.NET module because the IIS 6 pipeline will handle those requests itself and ASP.NET will never see those requests because they were never handed off.* On the other hand, authorizing which users can access a .ASPX page such as a request for Foo.aspx is trivial even in IIS 6/Classic because IIS always hands those requests off to the ASP.NET pipeline. In Classic mode ASP.NET does not know what it hasn't been told and there is a lot that IIS 6/Classic may not be telling it.
Integrated mode is recommended because ASP.NET handlers and modules can interact directly with the IIS pipeline. No longer does the IIS pipeline simply hand off the request to the ASP.NET pipeline, now it allows ASP.NET code to hook directly into the IIS pipeline and all the requests that hit it. This means that an ASP.NET module can not only observe requests to static image files, but can intercept those requests and take action by denying access, logging the request, etc.
Overcoming the error:
Then again maybe you are giving your application a face-lift or it was chugging along just fine until you installed a 3rd party library via NuGet, manually, or by some other means. In that case it is entirely possible httpHandlers
or httpModules
have been added to system.web
. The outcome is the error that you are seeing because validateIntegratedModeConfiguration
defaults true
. Now you have two choices:
httpHandlers
and httpModules
elements from system.web
. There are a couple possible outcomes from this:
httpHandlers
and httpModules
that NuGet packages keep adding to system.web
, hey do what you need to.validateIntegratedModeConfiguration
to false
, but at least you know what you're doing and why it matters.Good reads:
*Of course there are ways to get all kind of strange things into the ASP.NET pipeline from IIS 6/Classic via incantations like wildcard mappings, if you like that sort of thing.
I use Tim Pope's vim-commentary plugin.
In my benchmark script, each method is tested 10000 times and the difference of the total time for each method is printed. You should this on your own configuration, I'm sure results will vary!
These are my results:
SELECT NULL" -> PGO()
faster by ~ 0.35 secondsSHOW TABLE STATUS" -> mysqli()
faster by ~ 2.3 secondsSELECT * FROM users" -> mysqli()
faster by ~ 33 secondsNote: by using ->fetch_row() for mysqli, the column names are not added to the array, I didn't find a way to do that in PGO. But even if I use ->fetch_array() , mysqli is slightly slower but still faster than PGO (except for SELECT NULL).
NSMutableArray *persons = [NSMutableArray array];
for (int i = 0; i < myPersonsCount; i++) {
[persons addObject:[[Person alloc] init]];
}
NSArray *arrayOfPersons = [NSArray arrayWithArray:persons]; // if you want immutable array
also you can reach this without using NSMutableArray:
NSArray *persons = [NSArray array];
for (int i = 0; i < myPersonsCount; i++) {
persons = [persons arrayByAddingObject:[[Person alloc] init]];
}
One more thing - it's valid for ARC enabled environment, if you going to use it without ARC don't forget to add autoreleased objects into array!
[persons addObject:[[[Person alloc] init] autorelease];
There are three good answers to this question.

I amended the code from stej (which was great, just what i needed!) to use larger buffer, [long] for larger files and used System.Diagnostics.Stopwatch class to track elapsed time and estimate time remaining.
Also added reporting of transfer rate during transfer and outputting overall elapsed time and overall transfer rate.

go to http://dev.mysql.com/downloads/connector/c/ and download MySQL Connector/C. after getting the package, make a new directory 'mysql', uncompress the Mysql Connector file under directory mysql, then under mysql, make another empty directory 'build'.we will use 'build' to build MySQL Connector/C. cd build && cmake ../your-MySQL-Connector-source-dir make && make install after make install, you will get a directory named mysql under /usr/local. it contains all the headers and libs you need.go to this dirctory, and copy the headers and libs to corresponding locations.

package, which provides higher level synchronization mechanisms, that are far less error prone than any of the low level stuff.
You can use js-cookie library to get and set JavaScript cookies.
Include to your HTML:
<script src="https://cdn.jsdelivr.net/npm/js-cookie@2/src/js.cookie.min.js"></script>
To create a Cookie:
Cookies.set('name', 'value');
To read a Cookie:
Cookies.get('name'); // => 'value'
Angular deprecated $cookieStore
in version 1.4.x, so use $cookies
instead if you are using latest version of angular. Syntax remain same for $cookieStore
& $cookies
:
$cookies.put("key", "value");
var value = $cookies.get("key");
See the Docs for an API overview. Mind also that the cookie service has been enhanced with some new important features like setting expiration (see this answer) and domain (see CookiesProvider Docs).
Note that, in version 1.3.x or below, $cookies has a different syntax than above:
$cookies.key = "value";
var value = $cookies.value;
Also if you are using bower, make sure to type your package name correctly:
bower install [email protected]
where X.Y.Z is the AngularJS version you are running. There's another package in bower "angular-cookie"(without the 's') which is not the official angular package.
C:\xampp\mysql\bin\mysql -u root -p testdatabase < C:\Users\Juan\Desktop\databasebackup.sql
That worked for me to import 400MB file into my database.
As astander has mentioned, you can do that with a UDF. However, for large sets using a scalar function (as oppoosed to a inline-table function) the performance will stink as the function is evaluated row-by-row. As an alternative, you could expose the same results via a stored procedure executing a fixed query with placeholders which substitutes in your parameter values.
(Here's a somewhat dated but still relevant article on row-by-row processing for scalar UDFs.)
Edit: comments re. degrading performance adjusted to make it clear this applies to scalar UDFs.
If you have epoch in milliseconds a possible solution is convert to seconds:

The best and the easiest ways to create a copy of a dict in both Python 2.7 and 3 are...
To create a copy of simple(single-level) dictionary:
1. Using dict() method, instead of generating a reference that points to the existing dict.
my_dict1 = dict()
my_dict1["message"] = "Hello Python"
print(my_dict1) # {'message':'Hello Python'}
my_dict2 = dict(my_dict1)
print(my_dict2) # {'message':'Hello Python'}
# Made changes in my_dict1
my_dict1["name"] = "Emrit"
print(my_dict1) # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2) # {'message':'Hello Python'}
2. Using the built-in update() method of python dictionary.
my_dict2 = dict()
my_dict2.update(my_dict1)
print(my_dict2) # {'message':'Hello Python'}
# Made changes in my_dict1
my_dict1["name"] = "Emrit"
print(my_dict1) # {'message':'Hello Python', 'name' : 'Emrit'}
print(my_dict2) # {'message':'Hello Python'}
To create a copy of nested or complex dictionary:
Use the built-in copy module, which provides a generic shallow and deep copy operations. This module is present in both Python 2.7 and 3.*
import copy
my_dict2 = copy.deepcopy(my_dict1)
Deleting all your migrations in the migration folder of your django app, then run makemigrations followed by migrate commands. You should be able to get out of the woods.
From the HashSet<T>
page on MSDN:
The HashSet(Of T) class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order.
(emphasis mine)
Of course there is. In Python 2.7.2+...
import MySQLdb as mdb
con = mdb.connect('localhost', 'user', 'password', 'db');
cur = con.cursor()
cur.execute('SELECT Foo, Bar FROM Table')
for i in range(int(cur.numrows)):
foo, bar = cur.fetchone()
print 'foo = %s' % foo
print 'bar = %s' % bar
I've also had success under linux using shutdown()

If you want give some default value to a parameter assign value in (). like (x =10). But important is first should compulsory argument then default value.
eg.
(y, x =10)
but
(x=10, y) is wrong
Not sure what isn't working in your case, but the following code will put a formula into cell A1 that will retrieve the value in the cell G2.
strProjectName = "Sheet1"
Cells(1, 1).Formula = "=" & strProjectName & "!" & Cells(2, 7).Address
The workbook and worksheet that strProjectName
references must exist at the time that this formula is placed. Excel will immediately try to evaluate the formula. You might be able to stop that from happening by turning off automatic recalculation until the workbook does exist.
Google has a YouTube Android Player API that enables you to incorporate video playback functionality into your Android applications. The API itself is very easy to use and works well. For example, here is how to create a new activity to play a video using the API.
Intent intent = YouTubeStandalonePlayer.createVideoIntent(this, "<<YOUTUBE_API_KEY>>", "<<Youtube Video ID>>", 0, true, false);
startActivity(intent);
See this for more details.
You can do it like this:
<input type="hidden" name="result" value="<?php foreach($postvalue as $value) echo $postvalue.","; ?>">
import socket
def is_valid_ipv4_address(address):
try:
socket.inet_pton(socket.AF_INET, address)
except AttributeError: # no inet_pton here, sorry
try:
socket.inet_aton(address)
except socket.error:
return False
return address.count('.') == 3
except socket.error: # not a valid address
return False
return True
def is_valid_ipv6_address(address):
try:
socket.inet_pton(socket.AF_INET6, address)
except socket.error: # not a valid address
return False
return True
I.e. for Visual Studio 2013 I would reference this assembly:
Microsoft.VisualStudio.Shell.14.0.dll
You can find it i.e. here:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\BugAid Software\BugAid\1.0
and don't forget to implement:
using Microsoft.VisualStudio;
A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:
.clear { height: 50px; width: 25px; }
Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both;
attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:
.clear { clear: both; }
An answer from askUbuntu works.
For pip2.7, you can at first curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
, then python2.7 get-pip.py --force-reinstall
to reinstall pip.
Problem solved. Also works for python3.
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.
Copied from IIS Modules Overview: Preconditions
Here is a simple wrapper solution for this:
var fs = require('fs')
function getFileRealPath(s){
try {return fs.realpathSync(s);} catch(e){return false;}
}
Usage:
Example:
var realPath,pathToCheck='<your_dir_or_file>'
if( (realPath=getFileRealPath(pathToCheck)) === false){
console.log('file/dir not found: '+pathToCheck);
} else {
console.log('file/dir exists: '+realPath);
}
Make sure you use === operator to test if return equals false. There is no logical reason that fs.realpathSync() would return false under proper working conditions so I think this should work 100%.
I would prefer to see a solution that does not does not generate an Error and resulting performance hit. From an API perspective, fs.exists() seems like the most elegant solution.
So it depends on which Java version you are trying-
Arrays.asList(1, 2, 3);
OR
final String arr[] = new String[] { "G", "E", "E", "K" };
final List<String> initialList = new ArrayList<String>() {{
add("C");
add("O");
add("D");
add("I");
add("N");
}};
// Elements of the array are appended at the end
Collections.addAll(initialList, arr);
OR
Integer[] arr = new Integer[] { 1, 2, 3 };
Arrays.asList(arr);
int[] num = new int[] {1, 2, 3};
List<Integer> list = Arrays.stream(num)
.boxed().collect(Collectors.<Integer>toList())
Reference - http://www.codingeek.com/java/how-to-convert-array-to-list-in-java/
First the quick and dirty way, and second the precise way (recognizing daylight's savings or not).
import time
time.ctime() # 'Mon Oct 18 13:35:29 2010'
time.strftime('%l:%M%p %Z on %b %d, %Y') # ' 1:36PM EDT on Oct 18, 2010'
time.strftime('%l:%M%p %z on %b %d, %Y') # ' 1:36PM EST on Oct 18, 2010'
While not in the standard library exactly, https://github.com/swenson/sort has just two header files you can include to get access to a wide range of incredibly fast sorting routings, like so:
#define SORT_NAME int64 #define SORT_TYPE int64_t #define SORT_CMP(x, y) ((x) - (y)) #include "sort.h" /* You now have access to int64_quick_sort, int64_tim_sort, etc., e.g., */ int64_quick_sort(arr, 128); /* Assumes you have some int *arr or int arr[128]; */
This should be at least twice as fast as the standard library qsort
, since it doesn't use function pointers, and has many other sorting algorithm options to choose from.
It's in C89, so should work in basically every C compiler.
I feel like adding more details to the existing answer:
# PHP error handling for development servers
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on

Give 777 or 755 permission to the log file and then add the code
<Files php_errors.log>
Order allow,deny
Deny from all
Satisfy All
</Files>
at the end of .htaccess. This will protect your log file.
These options are suited for a development server. For a production server you should not display any error to the end user. So change the display flags to off.

On modern browsers, you can use the input

$("#textbox").on('input',function() {alert("Change detected!");});
By far the most convenient way is using this:
df.orderBy(df.column_name.desc())
Doesn't require special imports.
Right click the project.

This works best:
git fetch origin specific_commit
git checkout -b temp FETCH_HEAD

Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?
I think you would want to add an 'onSelect' event handler to the initialization of your datepicker so your code gets triggered when the user selects a date. Try it out on jsFiddle
$(document).ready(function(){
// Datepicker
$('#datepicker').datepicker({
dateFormat: 'yy-mm-dd',
inline: true,
minDate: new Date(2010, 1 - 1, 1),
maxDate:new Date(2010, 12 - 1, 31),
altField: '#datepicker_value',
onSelect: function(){
var day1 = $("#datepicker").datepicker('getDate').getDate();
var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1;
var year1 = $("#datepicker").datepicker('getDate').getFullYear();
var fullDate = year1 + "-" + month1 + "-" + day1;
var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
$('#page_output').html(str_output);
}
});
});
If you wish to use CV2, you need to use the resize
function.
For example, this will resize both axes by half:
small = cv2.resize(image, (0,0), fx=0.5, fy=0.5)
and this will resize the image to have 100 cols (width) and 50 rows (height):
resized_image = cv2.resize(image, (100, 50))
Another option is to use scipy
module, by using:
small = scipy.misc.imresize(image, 0.5)
There are obviously more options you can read in the documentation of those functions (cv2.resize, scipy.misc.imresize).
Update:
According to the SciPy documentation:
imresize
is deprecated in SciPy 1.0.0, and will be removed in 1.2.0.
Useskimage.transform.resize
instead.
Note that if you're looking to resize by a factor, you may actually want skimage.transform.rescale
.
As explained @Yaroslav Stavnichiy if a service is marked as transactional spring tries to handle transaction itself. If any exception occurs then a rollback operation performed. If in your scenario ServiceUser.method() is not performing any transactional operation you can use @Transactional.TxType annotation. 'NEVER' option is used to manage that method outside transactional context.
Transactional.TxType reference doc is here.
This is an old question but it has a high view count, so I think some new information should be added: In the mean time a lot has changed, and you can now also use Microsoft's own .NET Core on linux. It's also available in ARM builds, 32 and 64 bit.
Other answers here seem to use jQuery and CSS links.
This code uses vanilla JavaScript. It creates a new <style>
element. It sets the text content of that element to be a string containing the new CSS. And it appends that element directly to the iframe document's head.
var iframe = document.getElementById('the-iframe');
var style = document.createElement('style');
style.textContent =
'.some-class-name {' +
' some-style-name: some-value;' +
'}'
;
iframe.contentDocument.head.appendChild(style);
If you get the error even after following the above step. then try below.
Since it is a node script. I am using the below option to create as of now.
node C:\Users\Administrator\AppData\Roaming\npm\node_modules\angular-cli\bin\ng version
May be symbolic links are required. Not researched further.
On Further Research: Set Path as : %PATH%;C:\Users\Administrator\AppData\Roaming\npm;
In Windows, npm.cmd file is in the above path. If the above Environment variable is set, you can execute as ng version ng init
Give the path of the script, that is, path setting by cmd:
$> . c:\program file\prog.ps1
Run the entry point function of PowerShell:
For example, $> add or entry_func or main

If you're asking when you should use what, I generally use print_r()
for displaying values and var_dump()
for when having issues with variable types.
The general answer is to grant execute permission as explained above. But that doesn't work if the schema owner of SP is different to underlying objects.
Check schema owners by:
select name, USER_NAME(s.principal_id) AS Schema_Owner from sys.schemas s
To change the owner of an schema you can:
ALTER AUTHORIZATION ON SCHEMA::YOUR_SCHEMA TO YOUR_USER;
Examples:
ALTER AUTHORIZATION ON SCHEMA::Claim TO dbo
ALTER AUTHORIZATION ON SCHEMA::datix TO user1;
Finally if within your SP you are truncating a table or changing structure you may want to add WITH EXECUTE AS OWNER in your SP:
ALTER procedure [myProcedure]
WITH EXECUTE AS OWNER
as
truncate table etl.temp
Here's a simple class for URL Validation using RegEx and then cross-references the domain against popular RBL (Realtime Blackhole Lists) servers:
Install:
require 'URLValidation.php';
Usage:
require 'URLValidation.php';
$urlVal = new UrlValidation(); //Create Object Instance
Add a URL as the parameter of the domain()
method and check the the return.
$urlArray = ['http://www.bokranzr.com/test.php?test=foo&test=dfdf', 'https://en-gb.facebook.com', 'https://www.google.com'];
foreach ($urlArray as $k=>$v) {
echo var_dump($urlVal->domain($v)) . ' URL: ' . $v . '<br>';
}
Output:
bool(false) URL: http://www.bokranzr.com/test.php?test=foo&test=dfdf
bool(true) URL: https://en-gb.facebook.com
bool(true) URL: https://www.google.com
As you can see above, www.bokranzr.com is listed as malicious website via an RBL so the domain was returned as false.
First make sure that the folder in which your .mdf file resides is not read only. If it is, un-check that option and make sure it reflects to folders and files within that folder.
Once that is done, Open Management Studio, in the Object Explorer right click on the Database which is read only and select Properties. In the Options Menu, check that the Read-Only property is false.
I wrote a hasAttr() plugin for jquery that will do all of this very simply, exactly as the OP has requested. More information here
EDIT: My plugin was deleted in the great plugins.jquery.com database deletion disaster of 2010. You can look here for some info on adding it yourself, and why it hasn't been added.
Do you mean search and replace a string in all files matched by grep?
perl -p -i -e 's/oldstring/newstring/g' `grep -ril searchpattern *`
Edit
Since this seems to be a fairly popular question thought I'd update.
Nowadays I mostly use ack-grep
as it's more user-friendly. So the above command would be:
perl -p -i -e 's/old/new/g' `ack -l searchpattern`
To handle whitespace in file names you can run:
ack --print0 -l searchpattern | xargs -0 perl -p -i -e 's/old/new/g'
you can do more with ack-grep
. Say you want to restrict the search to HTML files only:
ack --print0 --html -l searchpattern | xargs -0 perl -p -i -e 's/old/new/g'
And if white space is not an issue it's even shorter:
perl -p -i -e 's/old/new/g' `ack -l --html searchpattern`
perl -p -i -e 's/old/new/g' `ack -f --html` # will match all html files
For Python 3.4+:
import csv
from pathlib import Path
base_path = Path(__file__).parent
file_path = (base_path / "../data/test.csv").resolve()
with open(file_path) as f:
test = [line for line in csv.reader(f)]
I'd do it like this:
<select onchange="jsFunction()">
<option value="" disabled selected style="display:none;">Label</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
If you want you could have the same label as the first option, which in this case is 1. Even better: put a label in there for the choices in the box.
At first glance one really wants to use New-PSDrive
supplying it credentials.
> New-PSDrive -Name P -PSProvider FileSystem -Root \\server\share -Credential domain\user
New-PSDrive : Cannot retrieve the dynamic parameters for the cmdlet. Dynamic parameters for NewDrive cannot be retrieved for the 'FileSystem' provider. The provider does not support the use of credentials. Please perform the operation again without specifying credentials.
The documentation states that you can provide a PSCredential
object but if you look closer the cmdlet does not support this yet. Maybe in the next version I guess.
Therefore you can either use net use
or the WScript.Network
object, calling the MapNetworkDrive
function:
$net = new-object -ComObject WScript.Network
$net.MapNetworkDrive("u:", "\\server\share", $false, "domain\user", "password")
Apparently with newer versions of PowerShell, the New-PSDrive
cmdlet works to map network shares with credentials!
New-PSDrive -Name P -PSProvider FileSystem -Root \\Server01\Public -Credential user\domain -Persist
You could just add a few COUNTIF
statements together:
=COUNTIF(A1:A196,"yes")+COUNTIF(A1:A196,"no")+COUNTIF(J1:J196,"agree")
This will give you the result you need.
EDIT
Sorry, misread the question. Nicholas is right that the above will double count. I wasn't thinking of the AND
condition the right way. Here's an alternative that should give you the correct results, which you were pretty close to in the first place:
=SUM(COUNTIFS(A1:A196,{"yes","no"},J1:J196,"agree"))

let filtervalue = filterobj[filterkey];
myobjects.forEach(function (objectToFilter) {
if (!filtervalue.some(x=>x==objectToFilter[filterkey]) && filtervalue != "") {
// object didn't match a filter value so remove it from array via filter
returnobjects = returnobjects.filter(obj => obj !== objectToFilter);

});
TL;DR;
In most cases, granting access to the following account(s) (one|both) will be enough:
with Access Rights:
That's it!
Read on for a more detailed explanation...
Grant access to the web application folder's ACL depending what is selected in the pic above:
IUSR
(in my case) + IIS AppPool\DefaultAppPool
IIS AppPool\DefaultAppPool
onlyIIS AppPool\DefaultAppPool
account is the default AppPool account for new IIS web applications, if you have set a custom account, use the custom one.
Give the following permissions to the account(s):
Read & Execute
List folder contents
Read
if you have any version problems (javac -version=15.0.1, java -version=1.8.0)
windows search : edit environment variables for your account
then delete these in your windows Environment variable: system variable: Path
C:\Program Files (x86)\Common Files\Oracle\Java\javapath
C:\Program Files\Common Files\Oracle\Java\javapath
then if you're using java 15
environment variable: system variable : Path
add path C:\Program Files\Java\jdk-15.0.1\bin
is enough
if you're using java 8
Assuming t1 is the folder with files in it, and t2 is the empty directory. What you want is something like this:
sudo cp -R t1/* t2/
Bear in mind, for the first example, t1 and t2 have to be the full paths, or relative paths (based on where you are). If you want, you can navigate to the empty folder (t2) and do this:
sudo cp -R t1/* ./
Or you can navigate to the folder with files (t1) and do this:
sudo cp -R ./* t2/
Note: The * sign (or wildcard) stands for all files and folders. The -R flag means recursively (everything inside everything).
^[1-9]*$ is the simplest I can think of
The name of the array indicates the starting address. Starting address of both namet2
and nameIt2
are different. So the equal to (==
) operator checks whether the addresses are the same or not. For comparing two strings, a better way is to use strcmp()
, or we can compare character by character using a loop.
Use Python's json module, or simplejson if you don't have python 2.6 or higher.
One liner as suggested here
How to determine one year from now in Javascript by JP DeVries
new Date(new Date().setFullYear(new Date().getFullYear() + 1))
Or you can get the number of years from somewhere in a variable:
const nr_years = 3;
new Date(new Date().setFullYear(new Date().getFullYear() + nr_years))
You could make use of Prepared Stements
like this.
set @query = concat( "select name from " );
set @query = concat( "table_name"," [where condition] " );
prepare stmt from @like_q;
execute stmt;
You can do this by using the --prefix
flag and the --global
* flag.
pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules
[email protected] /Users/pje/foo/vendor/node_modules/bower
*Even though this is a "global" installation, installed bins won't be accessible through the command line unless ~/foo/vendor/node_modules
exists in PATH
.
Every configurable attribute of npm
can be set in any of six different places. In order of priority:
--prefix ./vendor/node_modules
NPM_CONFIG_PREFIX=./vendor/node_modules
$HOME/.npmrc
or userconfig
param$PREFIX/etc/npmrc
or userconfig
parampath/to/npm/itself/npmrc
By default, locally-installed packages go into ./node_modules
. global ones go into the prefix
config variable (/usr/local
by default).
You can run npm config list
to see your current config and npm config edit
to change it.
In general, npm
's documentation is really helpful. The folders section is a good structural overview of npm and the config section answers this question.
Internally devtools injects an IIFE named getCompletions
into the page, called when a key is pressed inside the Devtools console.
Looking at the source of that function, it uses a few global functions which can be overwritten.
By using the Error
constructor it's possible to get the call stack, which will include getCompletions
when called by Devtools.
Example:
const disableDevtools = callback => {_x000D_
const original = Object.getPrototypeOf;_x000D_
_x000D_
Object.getPrototypeOf = (...args) => {_x000D_
if (Error().stack.includes("getCompletions")) callback();_x000D_
return original(...args);_x000D_
};_x000D_
};_x000D_
_x000D_
disableDevtools(() => {_x000D_
console.error("devtools has been disabled");_x000D_
_x000D_
while (1);_x000D_
});
_x000D_
For identifying NaN
values use boolean indexing
:
print(df[df['x'].isnull()])
Then for removing all non-numeric values use to_numeric
with parameter errors='coerce'
- to replace non-numeric values to NaN
s:
df['x'] = pd.to_numeric(df['x'], errors='coerce')
And for remove all rows with NaN
s in column x
use dropna
:
df = df.dropna(subset=['x'])
Last convert values to int

A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)
I can't guarantee it's the simplest, but I like MarkerWithLabel. As shown in the basic example, CSS styles define the label's appearance and options in the JavaScript define the content and placement.
.labels {
color: red;
background-color: white;
font-family: "Lucida Grande", "Arial", sans-serif;
font-size: 10px;
font-weight: bold;
text-align: center;
width: 60px;
border: 2px solid black;
white-space: nowrap;
}
JavaScript:
var marker = new MarkerWithLabel({
position: homeLatLng,
draggable: true,
map: map,
labelContent: "$425K",
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: {opacity: 0.75}
});
The only part that may be confusing is the labelAnchor. By default, the label's top left corner will line up to the marker pushpin's endpoint. Setting the labelAnchor's x-value to half the width defined in the CSS width property will center the label. You can make the label float above the marker pushpin with an anchor point like new google.maps.Point(22, 50)
.
In case access to the links above are blocked, I copied and pasted the packed source of MarkerWithLabel into this JSFiddle demo. I hope JSFiddle is allowed in China :|

Use t
function:
t(colnames(df))
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] "var1" "var2" "var3" "var4" "var5" "var6"
A simple regex should be efficent to check your textarea:
/\s*\d+\s*\n/g.test(text) ? "OK" : "KO"
First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.
If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
'do something
End If
End If
Try with Contains
function;
Determines whether a sequence contains a specified element.
var allowedStatus = new[]{ "A", "B", "C" };
var filteredOrders = orders.Order.Where(o => allowedStatus.Contains(o.StatusCode));
For getting all post parameters there is Map which contains request param name as key and param value as key.
Map params = servReq.getParameterMap();
And to get parameters with known name normal
String userId=servReq.getParameter("user_id");
Another option is to use Symbols in your module. This way you can protect your class, also if the final user of your API is using normal Javascript:
let _instance = Symbol();
export default class Singleton {
constructor(singletonToken) {
if (singletonToken !== _instance) {
throw new Error("Cannot instantiate directly.");
}
//Init your class
}
static get instance() {
return this[_instance] || (this[_instance] = new Singleton(_singleton))
}
public myMethod():string {
return "foo";
}
}
Usage:
var str:string = Singleton.instance.myFoo();
If the user is using your compiled API js file, also will get an error if he try to instantiate manually your class:
// PLAIN JAVASCRIPT:
var instance = new Singleton(); //Error the argument singletonToken !== _instance symbol

You can add hash info in next page url to move browser at specific position(any html element), after page is loaded.
This is can done in this way:
add hash in the url of next_page : example.com#hashkey
$( document ).ready(function() {
##get hash code at next page
var hashcode = window.location.hash;
## move page to any specific position of next page(let that is div with id "hashcode")
$('html,body').animate({scrollTop: $('div#'+hascode).offset().top},'slow');
});
I recently needed to accomplish something similar to this. I used the following design to access the paste element and value. jsFiddle demo
$('body').on('paste', 'input, textarea', function (e)
{
setTimeout(function ()
{
//currentTarget added in jQuery 1.3
alert($(e.currentTarget).val());
//do stuff
},0);
});
Quick Answer:
foreach (var process in Process.GetProcessesByName("whatever"))
{
process.Kill();
}
(leave off .exe from process name)
Suppose your existing reporting query is
Select EmployeeId,EmployeeName
from Employee
Where EmployeeId>101 order by EmployeeName
and you have to save this data into temparory table then you query goes to
Select EmployeeId,EmployeeName
into #MyTempTable
from Employee
Where EmployeeId>101 order by EmployeeName
Bash supports all sorts of wildcards and expansions.
Your exact case would be handled by brace expansion, like so:
$ rm -rf abc.log.2012-03-{14,27,28}
The above would expand to a single command with all three arguments, and be equivalent to typing:
$ rm -rf abc.log.2012-03-14 abc.log.2012-03-27 abc.log.2012-03-28
It's important to note that this expansion is done by the shell, before rm
is even loaded.
You can use the dynamic variable ViewBag
ViewBag.AnotherValue = valueToView;

For those who are searching custom border and shape of ImageView. You can use android-shape-imageview
Just add compile 'com.github.siyamed:android-shape-imageview:0.9.+@aar'
to your build.gradle
.
And use in your layout.
<com.github.siyamed.shapeimageview.BubbleImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/neo"
app:siArrowPosition="right"
app:siSquare="true"/>
I needed to do this and run a git pull in order to set my password from the command line in order to get this working.
Note this method saves your password in a plain text file on your disk:
git config --global credential.helper store
git pull

Iterating through the registry key "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" seems to give a comprehensive list of installed applications.
Aside from the example below, you can find a similar version to what I've done here.
This is a rough example, you'll probaby want to do something to strip out blank rows like in the 2nd link provided.
string registry_key = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
using(Microsoft.Win32.RegistryKey key = Registry.LocalMachine.OpenSubKey(registry_key))
{
foreach(string subkey_name in key.GetSubKeyNames())
{
using(RegistryKey subkey = key.OpenSubKey(subkey_name))
{
Console.WriteLine(subkey.GetValue("DisplayName"));
}
}
}
Alternatively, you can use WMI as has been mentioned:
ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
foreach(ManagementObject mo in mos.Get())
{
Console.WriteLine(mo["Name"]);
}
But this is rather slower to execute, and I've heard it may only list programs installed under "ALLUSERS", though that may be incorrect. It also ignores the Windows components & updates, which may be handy for you.
If you want to skip current iteration, use continue;
.
for(int i = 0; i < 5; i++){
if (i == 2){
continue;
}
}
Need to break out of the whole loop? Use break;
for(int i = 0; i < 5; i++){
if (i == 2){
break;
}
}
If you need to break out of more than one loop use break someLabel;
outerLoop: // Label the loop
for(int j = 0; j < 5; j++){
for(int i = 0; i < 5; i++){
if (i==2){
break outerLoop;
}
}
}
*Note that in this case you are not marking a point in code to jump to, you are labeling the loop! So after the break the code will continue right after the loop!
When you need to skip one iteration in nested loops use continue someLabel;
, but you can also combine them all.
outerLoop:
for(int j = 0; j < 10; j++){
innerLoop:
for(int i = 0; i < 10; i++){
if (i + j == 2){
continue innerLoop;
}
if (i + j == 4){
continue outerLoop;
}
if (i + j == 6){
break innerLoop;
}
if (i + j == 8){
break outerLoop;
}
}
}
For anyone looking for an answer in 2020. This worked for me.
In Views:
class InstancesView(generic.ListView):
model = AlarmInstance
context_object_name = 'settings_context'
queryset = Group.objects.all()
template_name = 'insta_list.html'
@register.filter
def filter_unknown(self, aVal):
result = aVal.filter(is_known=False)
return result
@register.filter
def filter_known(self, aVal):
result = aVal.filter(is_known=True)
return result
In template:
{% for instance in alarm.qar_alarm_instances|filter_unknown:alarm.qar_alarm_instances %}
In pseudocode:
For each in model.child_object|view_filter:filter_arg
Hope that helps.
To simply remove everything that is not currently used by a running container the following alias, that I usually put into the .bash_profile
on my Mac, will help:
alias dockerclean="docker ps -q -a | xargs docker rm -v && docker images -q | xargs docker rmi"
Whenever dockerclean
is invoked from the command line it will remove stopped containers as well as unused image layers. For running containers and used images it will print a warning message and skip over it.
create table question_bank
(
question_id uniqueidentifier primary key,
question_exam_id uniqueidentifier not null,
question_text varchar(1024) not null,
question_point_value decimal,
constraint fk_questionbank_exams foreign key (question_exam_id) references exams (exam_id)
);
You could use the following without the wrapper function, but it provides a nicer API:
Function IsInArray(ByVal findString as String, ByVal arrayToSearch as Variant) as Boolean
IsInArray = UBound(Filter(arrayToSearch,findString)) >= 0
End Function
The Filter
function has the following signature:
Filter(sourceArray, stringToMatch, [Include As Boolean = True], [Compare as VbCompareMethod = vbBinaryCompare])
Is there something that prevents you from merging all revisions on trunk since the last merge?
svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc
should work just fine. At least if you want to merge all changes on trunk to your branch.
If someone is using react, following will be useful:

const valueSetter = Object.getOwnPropertyDescriptor(this.textInputRef, 'value').set;
const prototype = Object.getPrototypeOf(this.textInputRef);
const prototypeValueSetter = Object.getOwnPropertyDescriptor(prototype, 'value').set;
if (valueSetter && valueSetter !== prototypeValueSetter) {
prototypeValueSetter.call(this.textInputRef, 'new value');
} else {
valueSetter.call(this.textInputRef, 'new value');
}
this.textInputRef.dispatchEvent(new Event('input', { bubbles: true }));
To remove any whitespaces you could use:
myValue := replace(replace(replace(replace(replace(replace(myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13));
Example: remove all whitespaces in a table:
update myTable t
set t.myValue = replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13))
where
length(t.myValue) > length(replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13)));
or
update myTable t
set t.myValue = replace(replace(replace(replace(replace(replace(t.myValue, chr(32)), chr(9)), chr(10)), chr(11)), chr(12)), chr(13))
where
t.myValue like '% %'

For that I have written the following code in the "ActionPeformed(...)" method of the "Start" button
You need that code to be in the actionPerformed(...)
of the ActionListener
registered with the Start button, not for the Start button itself.
You can add a simple ActionListener
like this:
JButton startButton = new JButton("Start");
startButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
startButton.setEnabled(false);
stopButton.setEnabled(true);
}
}
);
note that your startButton above will need to be final
in the above example if you want to create the anonymous listener in local scope.
After using all these mentioned solution, i was still not able to scroll using mouse scroll, keyboard up/down button were working for scrolling content.
So i have added below css fixes to make it working
.modal-open {
overflow: hidden;
}
.modal-open .modal {
overflow-x: hidden;
overflow-y: auto;
**pointer-events: auto;**
}
Added pointer-events: auto; to make it mouse scrollable.
It turns out that the problem really was that the address was busy - the busyness was caused by some other problems in how we are handling network communications. Your inputs have helped me figure this out. Thank you.
EDIT: to be specific, the problems in handling our network communications were that these status updates would be constantly re-sent if the first failed. It was only a matter of time until we had every distributed slave trying to send its status update at the same time, which was over-saturating our network.
Network tracing also available for next objects (see article on msdn)

One main reason we went with Workstation over Player at my job is because we need to run VMs that use a physical disk as their hard drive instead of a virtual disk. Workstation supports using physical disks while Player does not.
Above answer is very correct but I'm giving an easy step to do it:
private static final long[] THREE_CYCLES = new long[] { 100, 1000, 1000, 1000, 1000, 1000 };
public void longVibrate(View v)
{
vibrateMulti(THREE_CYCLES);
}
private void vibrateMulti(long[] cycles) {
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification();
notification.vibrate = cycles;
notificationManager.notify(0, notification);
}
And then in your xml file:
<button android:layout_height="wrap_content"
android:layout_width ="wrap_content"
android:onclick ="longVibrate"
android:text ="VibrateThrice">
</button>
That's the easiest way.
Try this:
TypeScript file code:
(<HTMLInputElement>document.getElementById("name")).value
HTML code:
<input id="name" type="text" #name />
You are right. ArrayList.contains() tests equals(), not object identity:
returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e))
If you got a NullPointerException, verify that you initialized your list, either in a constructor or the declaration. For example:
private List<String> rssFeedURLs = new ArrayList<String>();
If you are using vim in MAC OSX, unfortunately it comes with older verion, and not complied with clipboard options. Luckily, homebrew can easily solve this problem.
install vim:
brew install vim --with-lua --with-override-system-vim
install gui verion of vim:
brew install macvim --with-lua --with-override-system-vim
restart the terminal to take effect.
append the following line to ~/.vimrc
set clipboard=unnamed
now you can copy the line in vim withyy
and paste it system-wide.
The following Javascript snippet works in Chrome by using the new 'download' attribute of links and simulating a click.
function downloadWithName(uri, name) {
var link = document.createElement("a");
link.download = name;
link.href = uri;
link.click();
}
And the following example shows it's use:
downloadWithName("data:,Hello%2C%20World!", "helloWorld.txt")
On other solution might be to put an empty array in your for loop in the case where you don't want to display it
<div *ngFor="let thing of show ? stuff : []">
Where "stuff" is an array of "thing" and "show" the boolean to display or not the content
On Windows or Mac, you can find this setting under the General ? Editors ? Text Editors menu.
Cocoa Packet Analyzer is similar to WireShark but with a much better interface. http://www.tastycocoabytes.com/cpa/
So you are doing this a bit backwards. Typically you'd do something like this:
?<div class='article'>
Article 1
</div>
<div class='article'>
Article 2
</div>
<div class='article'>
Article 3
</div>?
And then in your jQuery:
$('.article').click(function(){
article = $(this).text(); //$(this) is what you clicked!
});?
When I see things like #search-item .search-article
, #search-item .search-article
, and #search-item .search-article
I sense you are overspecifying your CSS which makes writing concise jQuery very difficult. This should be avoided if at all possible.
Cache-Control: no-cache, no-store
These two header values can be combined to get the required effect on both IE and Firefox
Also, you can call into Objective-C runtime to call the method.
What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:
x = ["0", "1", "2"]
y = int(x[0]) #accessing the zeroth element
If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:
x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)
If your list elements are not strings, you'll have to convert them to strings before using str.join
:
x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)
Also, as stated above, make sure that you're not returning a nested list.
If you want to use names, try a namedtuple:
from collections import namedtuple
Pair = namedtuple("Pair", ["first", "second"])
pairs = [Pair("a", 1), Pair("b", 2), Pair("c", 3)]
for pair in pairs:
print("First = {}, second = {}".format(pair.first, pair.second))
See this question for reference:
How can I convert a string to boolean in JavaScript?
There are a few ways:
// Watch case sensitivity!
var boolVal = (string == "true");
or
var boolVal = Boolean("false");
or
String.prototype.bool = function() {
return (/^true$/i).test(this);
};
alert("true".bool());
I know this question is a few years old, but as Java 8 has, in the meantime, brought us Optional
, I thought I'd offer up a solution using it (and Stream
and Collectors
):
public enum PcapLinkType {
DLT_NULL(0),
DLT_EN3MB(2),
DLT_AX25(3),
/*snip, 200 more enums, not always consecutive.*/
// DLT_UNKNOWN(-1); // <--- NO LONGER NEEDED
private final int value;
private PcapLinkType(int value) { this.value = value; }
private static final Map<Integer, PcapLinkType> map;
static {
map = Arrays.stream(values())
.collect(Collectors.toMap(e -> e.value, e -> e));
}
public static Optional<PcapLinkType> fromInt(int value) {
return Optional.ofNullable(map.get(value));
}
}
Optional
is like null
: it represents a case when there is no (valid) value. But it is a more type-safe alternative to null
or a default value such as DLT_UNKNOWN
because you could forget to check for the null
or DLT_UNKNOWN
cases. They are both valid PcapLinkType
values! In contrast, you cannot assign an Optional<PcapLinkType>
value to a variable of type PcapLinkType
. Optional
makes you check for a valid value first.
Of course, if you want to retain DLT_UNKNOWN
for backward compatibility or whatever other reason, you can still use Optional
even in that case, using orElse()
to specify it as the default value:
public enum PcapLinkType {
DLT_NULL(0),
DLT_EN3MB(2),
DLT_AX25(3),
/*snip, 200 more enums, not always consecutive.*/
DLT_UNKNOWN(-1);
private final int value;
private PcapLinkType(int value) { this.value = value; }
private static final Map<Integer, PcapLinkType> map;
static {
map = Arrays.stream(values())
.collect(Collectors.toMap(e -> e.value, e -> e));
}
public static PcapLinkType fromInt(int value) {

See http://caniuse.com/#search=minlength. Some browsers may not support this attribute.
If the value of the "type" is one of them:
text, email, search, password, tel, or URL (warning: not include number | no browser support "tel" now - 2017.10)
Use the minlength(/ maxlength) attribute. It specifies the minimum number of characters.
For example,
<input type="text" minlength="11" maxlength="11" pattern="[0-9]*" placeholder="input your phone number">
Or use the "pattern" attribute:
<input type="text" pattern="[0-9]{11}" placeholder="input your phone number">
If the "type" is number, although minlength(/ maxlength) is not be supported, you can use the min(/ max) attribute instead of it.
For example,
<input type="number" min="100" max="999" placeholder="input a three-digit number">
I had the same problem, but it turned out to be a chrome extension called hola (or Proxy SwitchySharp), that messed with the proxy settings. Removing Hola fixed the problem
At some point, isn't it easier(or just as easy) to use a forEach
var options = [_x000D_
{ name: 'One', assigned: true }, _x000D_
{ name: 'Two', assigned: false }, _x000D_
{ name: 'Three', assigned: true }, _x000D_
];_x000D_
_x000D_
var reduced = []_x000D_
options.forEach(function(option) {_x000D_
if (option.assigned) {_x000D_
var someNewValue = { name: option.name, newProperty: 'Foo' }_x000D_
reduced.push(someNewValue);_x000D_
}_x000D_
});_x000D_
_x000D_
document.getElementById('output').innerHTML = JSON.stringify(reduced);

<h1>Only assigned options</h1>_x000D_

However it would be nice if there was a malter()
or fap()
function that combines the map
and filter
functions. It would work like a filter, except instead of returning true or false, it would return any object or a null/undefined.
You can also use:
Get-WmiObject -Class "Win32_computersystem" | Select *
This will show the same result as Format-List * used in the other answers here.
Updating to use tibble()
You can pass a named vector of length greater than 1 to the by
argument of left_join()
:
library(dplyr)
d1 <- tibble(
x = letters[1:3],
y = LETTERS[1:3],
a = rnorm(3)
)
d2 <- tibble(
x2 = letters[3:1],
y2 = LETTERS[3:1],
b = rnorm(3)
)
left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))
To convert array to object using stdClass just add (object)
to array u declare.
EX:
echo $array['value'];
echo $object->value;
to convert object to array
$obj = (object)$array;
to convert array to object
$arr = (array)$object
with these methods you can swap between array and object very easily.
Another method is to use json
$object = json_decode(json_encode($array), FALSE);
But this is a much more memory intensive way to do and is not supported by versions of PHP <= 5.1
You could run: mvn exec:exec -Dexec.args="arg1"
.
This will pass the argument arg1 to your program.
You should specify the main class fully qualified, for example, a Main.java that is in a package test would need
mvn exec:java -Dexec.mainClass=test.Main
By using the -f
parameter, as decribed here, you can also run it from other directories.
mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm
For multiple arguments, simply separate them with a space as you would at the command line.
mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"
For arguments separated with a space, you can group using 'argument separated with space'
inside the quotation marks.
mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"
$route.reload()
will reinitialise the controllers but not the services. If you want to reset the whole state of your application you can use:
$window.location.reload();
This is a standard DOM method which you can access injecting the $window service.
If you want to be sure to reload the page from the server, for example when you are using Django or another web framework and you want a fresh server side render, pass true
as a parameter to reload
, as explained in the docs. Since that requires interaction with the server, it will be slower so do it only if necessary
The above applies to Angular 1. I am not using Angular 2, looks like the services are different there, there is Router
, Location
, and the DOCUMENT
. I did not test different behaviors there
The following will return true if the element is an input:
$("#elementId").is("input")
or you can use the following to get the name of the tag:
$("#elementId").get(0).tagName
You can't search a text field without converting it from text to varchar.
declare @table table (a text)
insert into @table values ('a')
insert into @table values ('a')
insert into @table values ('b')
insert into @table values ('c')
insert into @table values ('d')
select *
from @table
where a ='a'
This give an error:
The data types text and varchar are incompatible in the equal to operator.
Wheras this does not:
declare @table table (a varchar(max))
Interestingly, LIKE
still works, i.e.
where a like '%a%'
The compiled dll should have public Class.
I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?
Something like:
ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT
I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.
ALTER TABLE `content` auto_increment = MAX(`id`) + 1
Again, untested but I believe it will work.
If you'd prefer to do it in SQL, enter this query into the query window:
CREATE SCHEMA Test
Press CTRL + Enter to submit it, and you should see confirmation in the output pane underneath the query window. You'll have to right-click on an existing schema in the Object panel and click "Refresh All" to see it show up, though.
I have got an error on the first answer so I have changed some code line.

I wrote an unzipper in Javascript. It works.
It relies on Andy G.P. Na's binary file reader and some RFC1951 inflate logic from notmasteryet. I added the ZipFile class.
working example:
http://cheeso.members.winisp.net/Unzip-Example.htm (dead link)
The source:
http://cheeso.members.winisp.net/srcview.aspx?dir=js-unzip (dead link)
NB: the links are dead; I'll find a new host soon.
Included in the source is a ZipFile.htm demonstration page, and 3 distinct scripts, one for the zipfile class, one for the inflate class, and one for a binary file reader class. The demo also depends on jQuery and jQuery UI. If you just download the js-zip.zip file, all of the necessary source is there.
Here's what the application code looks like in Javascript:
// In my demo, this gets attached to a click event.
// it instantiates a ZipFile, and provides a callback that is
// invoked when the zip is read. This can take a few seconds on a
// large zip file, so it's asynchronous.
var readFile = function(){
$("#status").html("<br/>");
var url= $("#urlToLoad").val();
var doneReading = function(zip){
extractEntries(zip);
};
var zipFile = new ZipFile(url, doneReading);
};
// this function extracts the entries from an instantiated zip
function extractEntries(zip){
$('#report').accordion('destroy');
// clear
$("#report").html('');
var extractCb = function(id) {
// this callback is invoked with the entry name, and entry text
// in my demo, the text is just injected into an accordion panel.
return (function(entryName, entryText){
var content = entryText.replace(new RegExp( "\\n", "g" ), "<br/>");
$("#"+id).html(content);
$("#status").append("extract cb, entry(" + entryName + ") id(" + id + ")<br/>");
$('#report').accordion('destroy');
$('#report').accordion({collapsible:true, active:false});
});
}
// for each entry in the zip, extract it.
for (var i=0; i<zip.entries.length; i++) {
var entry = zip.entries[i];
var entryInfo = "<h4><a>" + entry.name + "</a></h4>\n<div>";
// contrive an id for the entry, make it unique
var randomId = "id-"+ Math.floor((Math.random() * 1000000000));
entryInfo += "<span class='inputDiv'><h4>Content:</h4><span id='" + randomId +
"'></span></span></div>\n";
// insert the info for one entry as the last child within the report div
$("#report").append(entryInfo);
// extract asynchronously
entry.extract(extractCb(randomId));
}
}
The demo works in a couple of steps: The readFile
fn is triggered by a click, and instantiates a ZipFile object, which reads the zip file. There's an asynchronous callback for when the read completes (usually happens in less than a second for reasonably sized zips) - in this demo the callback is held in the doneReading local variable, which simply calls extractEntries
, which
just blindly unzips all the content of the provided zip file. In a real app you would probably choose some of the entries to extract (allow the user to select, or choose one or more entries programmatically, etc).
The extractEntries
fn iterates over all entries, and calls extract()
on each one, passing a callback. Decompression of an entry takes time, maybe 1s or more for each entry in the zipfile, which means asynchrony is appropriate. The extract callback simply adds the extracted content to an jQuery accordion on the page. If the content is binary, then it gets formatted as such (not shown).
It works, but I think that the utility is somewhat limited.
For one thing: It's very slow. Takes ~4 seconds to unzip the 140k AppNote.txt file from PKWare. The same uncompress can be done in less than .5s in a .NET program. EDIT: The Javascript ZipFile unpacks considerably faster than this now, in IE9 and in Chrome. It is still slower than a compiled program, but it is plenty fast for normal browser usage.
For another: it does not do streaming. It basically slurps in the entire contents of the zipfile into memory. In a "real" programming environment you could read in only the metadata of a zip file (say, 64 bytes per entry) and then read and decompress the other data as desired. There's no way to do IO like that in javascript, as far as I know, therefore the only option is to read the entire zip into memory and do random access in it. This means it will place unreasonable demands on system memory for large zip files. Not so much a problem for a smaller zip file.
Also: It doesn't handle the "general case" zip file - there are lots of zip options that I didn't bother to implement in the unzipper - like ZIP encryption, WinZip encryption, zip64, UTF-8 encoded filenames, and so on. (EDIT - it handles UTF-8 encoded filenames now). The ZipFile class handles the basics, though. Some of these things would not be hard to implement. I have an AES encryption class in Javascript; that could be integrated to support encryption. Supporting Zip64 would probably useless for most users of Javascript, as it is intended to support >4gb zipfiles - don't need to extract those in a browser.
I also did not test the case for unzipping binary content. Right now it unzips text. If you have a zipped binary file, you'd need to edit the ZipFile class to handle it properly. I didn't figure out how to do that cleanly. It does binary files now, too.
EDIT - I updated the JS unzip library and demo. It now does binary files, in addition to text. I've made it more resilient and more general - you can now specify the encoding to use when reading text files. Also the demo is expanded - it shows unzipping an XLSX file in the browser, among other things.
So, while I think it is of limited utility and interest, it works. I guess it would work in Node.js.
I didn't use it myself but heard of a simple tool (not a text editor) for this so it is definitely possible without setting up a programming environment (by installing octave or python).
A quick search hints that it was possible with total commander. (A lightweight tool with an easy point and click interface)
I would not be surprised if this still works, but I can't guarantee it.
You might also be interested in the unit testing framework that is part of qooxdoo, an open source RIA framework similar to Dojo, ExtJS, etc. but with quite a comprehensive tool chain.
Try the online version of the testrunner. Hint: hit the gray arrow at the top left (should be made more obvious). It's a "play" button that runs the selected tests.

FINDSTR has a color bug that I described and solved at https://superuser.com/questions/1535810/is-there-a-better-way-to-mitigate-this-obscure-color-bug-when-piping-to-findstr/1538802?noredirect=1#comment2339443_1538802
To summarize that thread, the bug is that if input is piped to FINDSTR within a parenthesized block of code, inline ANSI escape colorcodes stop working in commands executed later. An example of inline colorcodes is: echo %magenta%Alert: Something bad happened%yellow%
(where magenta and yellow are vars defined earlier in the .bat file as the corresponding ANSI escape colorcodes).
My initial solution was to call a do-nothing subroutine after the FINDSTR. Somehow the call or the return "resets" whatever needs to be reset.
Later I discovered another solution that presumably is more efficient: place the FINDSTR phrase within parentheses, as in the following example:
echo success | ( FINDSTR /R success )
Placing the FINDSTR phrase within a nested block of code appears to isolate FINDSTR's colorcode bug so it won't affect what's outside the nested block. Perhaps this technique will solve some other undesired FINDSTR side effects too.
Have in mind though, that getExternalStorageDirectory() is not going to work properly on some phones e.g. my Motorola razr maxx, as it has 2 cards /mnt/sdcard and /mnt/sdcard-ext - for internal and external SD cards respectfully. You will be getting the /mnt/sdcard only reply every time. Google must provide a way to deal with such a situation. As it renders many SD card aware apps (i.e card backup) failing miserably on these phones.
Just running the SELECT
statement will have no effect on the data. You have to use an UPDATE
statement with the REPLACE
to make the change occur:
UPDATE photos
SET caption = REPLACE(caption,'"','\'')
Here is a working sample: http://sqlize.com/7FjtEyeLAh
I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.
I wonder why there are editors that don't default to utf-8.
We can do it this way -
mongo db_name --quiet --eval 'DBQuery.shellBatchSize = 2000; db.users.find({}).limit(2000).toArray()' > users.json
The shellBatchSize
argument is used to determine how many rows is the mongo client allowed to print. Its default value is 20.
SELECT date1 - date2
FROM some_table
returns a difference in days. Multiply by 24 to get a difference in hours and 24*60 to get minutes. So
SELECT (date1 - date2) * 24 * 60 difference_in_minutes
FROM some_table
should be what you're looking for
If you want to escape user input in a variable you can do like below within SQL
Set @userinput = replace(@userinput,'''','''''')
The @userinput will be now escaped with an extra single quote for every occurance of a quote
Please also see this Microsoft Connect report on essentially, how blummin' difficult it is to use PowerShell to run shell commands (oh, the irony).
http://connect.microsoft.com/PowerShell/feedback/details/376207/
They suggest using --%
as a way to force PowerShell to stop trying to interpret the text to the right.
For example:
MSBuild /t:Publish --% /p:TargetDatabaseName="MyDatabase";TargetConnectionString="Data Source=.\;Integrated Security=True" /p:SqlPublishProfilePath="Deploy.publish.xml" Database.sqlproj
The problem for me is that the repo's previous developer had committed the submodules/thing
folder as just a regular folder, meaning when I tried to run git submodule add ...
, it would fail with: 'submodules/thing' already exists in the index
, yet trying to update the submodule would also fail because it saw that the path did not contain a submodule.
To fix, I had to delete the submodules/thing
folder, commit the deletion, then run the git submodule add
command to add it back correctly:
git submodule add --force --name thing https://github.com/person/thing.git submodules/thing
This is, in essence, what AJAX is for. Your page loads, and you add an event to an element. When the user causes the event to be triggered, say by clicking something, your Javascript uses the XMLHttpRequest object to send a request to a server.
After the server responds (presumably with output), another Javascript function/event gives you a place to work with that output, including simply sticking it into the page like any other piece of HTML.
You can do it "by hand" with plain Javascript , or you can use jQuery. Depending on the size of your project and particular situation, it may be more simple to just use plain Javascript .
In this very basic example, we send a request to myAjax.php
when the user clicks a link. The server will generate some content, in this case "hello world!". We will put into the HTML element with the id output
.
The javascript
// handles the click event for link 1, sends the query
function getOutput() {
getRequest(
'myAjax.php', // URL for the PHP file
drawOutput, // handle successful request
drawError // handle error
);
return false;
}
// handles drawing an error message
function drawError() {
var container = document.getElementById('output');
container.innerHTML = 'Bummer: there was an error!';
}
// handles the response, adds the html
function drawOutput(responseText) {
var container = document.getElementById('output');
container.innerHTML = responseText;
}
// helper function for cross-browser request object
function getRequest(url, success, error) {
var req = false;
try{
// most browsers
req = new XMLHttpRequest();
} catch (e){
// IE
try{
req = new ActiveXObject("Msxml2.XMLHTTP");
} catch(e) {
// try an older version
try{
req = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
return false;
}
}
}
if (!req) return false;
if (typeof success != 'function') success = function () {};
if (typeof error!= 'function') error = function () {};
req.onreadystatechange = function(){
if(req.readyState == 4) {
return req.status === 200 ?
success(req.responseText) : error(req.status);
}
}
req.open("GET", url, true);
req.send(null);
return req;
}
The HTML
<a href="#" onclick="return getOutput();"> test </a>
<div id="output">waiting for action</div>
The PHP
// file myAjax.php
<?php
echo 'hello world!';
?>

Arguably, that is a lot of Javascript code. You can shorten that up by tightening the blocks or using more terse logic operators, of course, but there's still a lot going on there. If you plan on doing a lot of this type of thing on your project, you might be better off with a javascript library.
Using the same HTML and PHP from above, this is your entire script (with jQuery included on the page). I've tightened up the code a little to be more consistent with jQuery's general style, but you get the idea:
// handles the click event, sends the query
function getOutput() {
$.ajax({
url:'myAjax.php',
complete: function (response) {
$('#output').html(response.responseText);
},
error: function () {
$('#output').html('Bummer: there was an error!');
}
});
return false;
}

Don't rush out for jQuery just yet: adding any library is still adding hundreds or thousands of lines of code to your project just as surely as if you had written them. Inside the jQuery library file, you'll find similar code to that in the first example, plus a whole lot more. That may be a good thing, it may not. Plan, and consider your project's current size and future possibility for expansion and the target environment or platform.
If this is all you need to do, write the plain javascript once and you're done.

Apache Pig's COUNT UDF, operates on a bag, and therefore uses a single reducer to compute the number of rows. Instead you can manually set the number of reducers in a simple hadoop streaming script as follows:
$HADOOP_HOME/bin/hadoop jar $HADOOP_HOME/hadoop-streaming.jar -Dmapred.reduce.tasks=100 -input <input_path> -output <output_path> -mapper /bin/cat -reducer "wc -l"
Note that I manually set the number of reducers to 100, but you can tune this parameter. Once the map-reduce job is done, the result from each reducer is stored in a separate file. The final count of rows is the sum of numbers returned by all reducers. you can get the final count of rows as follows:
$HADOOP_HOME/bin/hadoop fs -cat <output_path>/* | paste -sd+ | bc
I had the same issue on a remote windows environment. I tried many solutions found here or on other similars posts but nothing worked. Finally, the solution was quite simple. I had to set NO_PROXY
with cmd :
set NO_PROXY="<domain>\<username>:<password>@<host>:<port>"
pip install <packagename>
You have to use double quotes and set NO_PROXY
to upper case. You can also add NO_PROXY
as an environment variable instead of setting it each time you use the console.
I hope this will help if any other solution posted here works.
I have added reCaptcha to a project I'm currently working on. I needed it to use the AJAX API as the reCaptcha element was loaded into the page dynamically. I couldn't find any existing controls and the API is simple so I created my own.

4: Add the captcha to your view
@using (Html.BeginForm("MyAction", "MyController"))
{
@Html.TextBox("EmailAddress", Model.EmailAddress)
@Html.GenerateCaptcha(Theme.White)
<input type="submit" value="Submit" />
}
5: Add the attribute to your action
[HttpPost]
[ReCaptcha]
public ActionResult MyAction(MyModel model)
{
if (!ModelState.IsValid) // Will have a Model Error "ReCaptcha" if the user input is incorrect
return Json(new { capthcaInvalid = true });
... other stuff ...
}
6: Note you will need to reload the captcha after each post even if it was valid and another part of the form was invalid. Use Recaptcha.reload();
Beware of the suggested perl solution: it removes anything after the first dot.
$ echo some.file.with.dots | perl -pe 's/\..*$//;s{^.*/}{}'
some
If you want to do it with perl, this works:
$ echo some.file.with.dots | perl -pe 's/(.*)\..*$/$1/;s{^.*/}{}'
some.file.with
But if you are using Bash, the solutions with y=${x%.*}
(or basename "$x" .ext
if you know the extension) are much simpler.
Using Java 8 streams:
double sum = m.stream()
.mapToDouble(a -> a)
.sum();
System.out.println(sum);
I had this same problem. For me, the reason turned out to be that I had a mismatch in the name of the class and the name of the file. I declared class "GenSig" in a file called "SignatureTester.java".
I changed the name of the class to "SignatureTester", and the "Run as Java Application" option showed up immediately.
Posting this late just for others..I bet the first coder is done by now. For simple datatypes no copy is needed, just revert to good old C code methods.
std::vector <int> myVec;
int *p;
// Add some data here and set start, then
p=myVec.data()+start;
Then pass the pointer p and a len to anything needing a subvector.
notelen must be!! len < myVec.size()-start
I am new to Angular but have found this to solve my issue:
<i class="icon-download" ng-click="showDetails = ! showDetails" ng-class="{'icon-upload': showDetails}"></i>
This will conditionally apply a class based on a var.
It starts off with a icon-download as a default, the using ng-class, I check the status of showDetails
if true/false
and apply class icon-upload. Its working great.
Hope it helps.
Try this:
$(document).ready(function(){
$("#showSimpleModal").click(function() {
$("div#simpleModal").addClass("show");
$("#videoContainer")[0].play();
return false;
});
$("#closeSimple").click(function() {
$("div#simpleModal").removeClass("show");
$("#videoContainer")[0].pause();
return false;
});
});
One other approach that we have taken successfully is to generate the WS client proxy code using wsimport (from Ant, as an Ant task) and specify the wsdlLocation attribute.
<wsimport debug="true" keep="true" verbose="false" target="2.1" sourcedestdir="${generated.client}" wsdl="${src}${wsdl.file}" wsdlLocation="${wsdl.file}">
</wsimport>
Since we run this for a project w/ multiple WSDLs, the script resolves the $(wsdl.file} value dynamically which is set up to be /META-INF/wsdl/YourWebServiceName.wsdl relative to the JavaSource location (or /src, depending on how you have your project set up). During the build proess, the WSDL and XSDs files are copied to this location and packaged in the JAR file. (similar to the solution described by Bhasakar above)
MyApp.jar
|__META-INF
|__wsdl
|__YourWebServiceName.wsdl
|__YourWebServiceName_schema1.xsd
|__YourWebServiceName_schmea2.xsd
Note: make sure the WSDL files are using relative refrerences to any imported XSDs and not http URLs:
<types>
<xsd:schema>
<xsd:import namespace="http://valueobject.common.services.xyz.com/" schemaLocation="YourWebService_schema1.xsd"/>
</xsd:schema>
<xsd:schema>
<xsd:import namespace="http://exceptions.util.xyz.com/" schemaLocation="YourWebService_schema2.xsd"/>
</xsd:schema>
</types>
In the generated code, we find this:
/**
* This class was generated by the JAX-WS RI.
* JAX-WS RI 2.2-b05-
* Generated source version: 2.1
*
*/
@WebServiceClient(name = "YourService", targetNamespace = "http://test.webservice.services.xyz.com/", wsdlLocation = "/META-INF/wsdl/YourService.wsdl")
public class YourService_Service
extends Service
{
private final static URL YOURWEBSERVICE_WSDL_LOCATION;
private final static WebServiceException YOURWEBSERVICE_EXCEPTION;
private final static QName YOURWEBSERVICE_QNAME = new QName("http://test.webservice.services.xyz.com/", "YourService");
static {
YOURWEBSERVICE_WSDL_LOCATION = com.xyz.services.webservice.test.YourService_Service.class.getResource("/META-INF/wsdl/YourService.wsdl");
WebServiceException e = null;
if (YOURWEBSERVICE_WSDL_LOCATION == null) {
e = new WebServiceException("Cannot find '/META-INF/wsdl/YourService.wsdl' wsdl. Place the resource correctly in the classpath.");
}
YOURWEBSERVICE_EXCEPTION = e;
}
public YourService_Service() {
super(__getWsdlLocation(), YOURWEBSERVICE_QNAME);
}
public YourService_Service(URL wsdlLocation, QName serviceName) {
super(wsdlLocation, serviceName);
}
/**
*
* @return
* returns YourService
*/
@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort() {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class);
}
/**
*
* @param features
* A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy. Supported features not in the <code>features</code> parameter will have their default values.
* @return
* returns YourService
*/
@WebEndpoint(name = "YourServicePort")
public YourService getYourServicePort(WebServiceFeature... features) {
return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class, features);
}
private static URL __getWsdlLocation() {
if (YOURWEBSERVICE_EXCEPTION!= null) {
throw YOURWEBSERVICE_EXCEPTION;
}
return YOURWEBSERVICE_WSDL_LOCATION;
}
}
Perhaps this might help too. It's just a different approach that does not use the "catalog" approach.
Try C# string interpolation introduced in C# 6:
var id = 100;
var hexid = $"0x{id:X}";
hexid value:
"0x64"
You can put dimens.xml
in
1) values
2) values-hdpi
3) values-xhdpi
4) values-xxhdpi
And give different sizes in dimens.xml
within corresponding folders according to densities.
git reset --hard origin/master
will remove all commits not in origin/master
where origin
is the repo name and master
is the name of the branch.
Using the -X
flag with whatever HTTP verb you want:
curl -X PUT -d arg=val -d arg2=val2 localhost:8080
This example also uses the -d
flag to provide arguments with your PUT request.
Make it simple and use R basic functions:
# To get the LEFT part:
> substr(a, 1, 4)
[1] "left"
>
# To get the MIDDLE part:
> substr(a, 3, 7)
[1] "ftrig"
>
# To get the RIGHT part:
> substr(a, 5, 10)
[1] "right"
The substr()
function tells you where start and stop substr(x, start, stop)
Try using Sublime Package Control to install your packages.
Also take a look at these tips
If anyone came here from python-graphql client looking for a solution to pass an object as variable here's what I used:
query = """
{{
pairs(block: {block} first: 200, orderBy: trackedReserveETH, orderDirection: desc) {{
id
txCount
reserveUSD
trackedReserveETH
volumeUSD
}}
}}
""".format(block=''.join(['{number: ', str(block), '}']))
query = gql(query)
Make sure to escape all curly braces like I did: "{{", "}}"
There is a simple function subtract
which moment library gives us to subtract time from some time.
Using it is also very simple.
moment(Date.now()).subtract(7, 'days'); // This will subtract 7 days from current time
moment(Date.now()).subtract(3, 'd'); // This will subtract 3 days from current time
//You can do this for days, years, months, hours, minutes, seconds
//You can also subtract multiple things simulatneously
//You can chain it like this.
moment(Date.now()).subtract(3, 'd').subtract(5. 'h'); // This will subtract 3 days and 5 hours from current time
//You can also use it as object literal
moment(Date.now()).subtract({days:3, hours:5}); // This will subtract 3 days and 5 hours from current time
Hope this helps!
Try this:-
printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getch();
getch()
is used to get a character from console but does not echo to the screen.
I think that you have Spring Security on your class path and then spring security is automatically configured with a default user and generated password
Please look into your pom.xml file for:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
If you have that in your pom than you should have a log console message like this:
Using default security password: ce6c3d39-8f20-4a41-8e01-803166bb99b6
And in the browser prompt you will import the user user
and the password printed in the console.
Or if you want to configure spring security you can take a look at Spring Boot secured example
It is explained in the Spring Boot Reference documentation in the Security section, it indicates:
The default AuthenticationManager has a single user (‘user’ username and random password, printed at `INFO` level when the application starts up)
Using default security password: 78fa095d-3f4c-48b1-ad50-e24c31d5cf35
You should call this function from the controller.
angular.module('App', [])
.controller('CinemaCtrl', ['$scope', function($scope) {
myFunction();
}]);
Even with normal javascript/html your function won't run on page load as all your are doing is defining the function, you never call it. This is really nothing to do with angular, but since you're using angular the above would be the "angular way" to invoke the function.
Obviously better still declare the function in the controller too.
Edit: Actually I see your "onload" - that won't get called as angular injects the HTML into the DOM. The html is never "loaded" (or the page is only loaded once).
a[len(a):]
- This gets you the length of a to the end. It selects a range. If you reverse a[:len(a)]
it will get you the beginning to whatever is len(a)
.
That's not a jQuery object, it's just an object.
You can use the hasOwnProperty method to check for a key:
if (obj.hasOwnProperty("key1")) {
...
}
Check
man paste
possible followed by some command like untabify
or tabs2spaces
add layout_gravity="center"
or "center_horizontal"
to the parent layout.
On a side note, your LinearLayout
inside your TableRow
seems un-necessary, as a TableRow
is already an horizontal LinearLayout
.
Starting with Chrome 38 you can do this without any plugins. Just click inspect element (or F12 hotkey), then click on toggle device mod
(the phone
button)
and you will see something like this:
Among many other features it allows you to simulate specific internet connection (3G, GPRS)
Transient :
First need to know where it needed how it bridge the gap.
1) An Access modifier transient is only applicable to variable component only. It will not used with method or class.
2) Transient keyword cannot be used along with static keyword.
3) What is serialization and where it is used? Serialization is the process of making the object's state persistent. That means the state of the object is converted into a stream of bytes to be used for persisting (e.g. storing bytes in a file) or transferring (e.g. sending bytes across a network). In the same way, we can use the deserialization to bring back the object's state from bytes. This is one of the important concepts in Java programming because serialization is mostly used in networking programming. The objects that need to be transmitted through the network have to be converted into bytes. Before understanding the transient keyword, one has to understand the concept of serialization. If the reader knows about serialization, please skip the first point.
Note 1) Transient is mainly use for serialzation process. For that the class must implement the java.io.Serializable interface. All of the fields in the class must be serializable. If a field is not serializable, it must be marked transient.
Note 2) When deserialized process taken place they get set to the default value - zero, false, or null as per type constraint.
Note 3) Transient keyword and its purpose? A field which is declare with transient modifier it will not take part in serialized process. When an object is serialized(saved in any state), the values of its transient fields are ignored in the serial representation, while the field other than transient fields will take part in serialization process. That is the main purpose of the transient keyword.
After installing Flutter, the best way to install Dart sdk is by creating a new project. In this window, click INSTALL SDK. This installs all necessary to work properly.
One of the way I like is this one , but may be good for small files
with open(fileName,'r') as content_file:
content = content_file.read()
lineCount = len(re.split("\n",content))
words = re.split("\W+",content.lower())
To count words, there is two way, if you don't care about repetition you can just do
words_count = len(words)
if you want the counts of each word you can just do
import collections
words_count = collections.Counter(words) #Count the occurrence of each word
? singleton method is a method that is defined only for a single object.
Example:
class SomeClass
class << self
def test

end
end
test_obj = SomeClass.new
def test_obj.test_2
end
class << test_obj
def test_3
end
end
puts "Singleton's methods of SomeClass"
puts SomeClass.singleton_methods
puts '------------------------------------------'
puts "Singleton's methods of test_obj"
puts test_obj.singleton_methods
Singleton's methods of SomeClass
test
Singleton's methods of test_obj

Some years have passed and there is now a proper Homebrew Tap for sshpass
, maintained by Aleks Hudochenkov. To install sshpass
from this tap, run:
brew install hudochenkov/sshpass/sshpass
HTML5 and the VLC web plugin were a no go for me but I was able to get this work using the following setup:
DivX Web Player (NPAPI browsers only)
And here is the HTML:
<embed id="divxplayer" type="video/divx" width="1024" height="768"
src ="path_to_file" autoPlay=\"true\"
pluginspage=\"http://go.divx.com/plugin/download/\"></embed>
The DivX player seems to allow for a much wider array of video and audio options than the native HTML5, so far I am very impressed by it.
You may also set {{ant.build.javac.target=1.5}}
ant property to update default target version of task.
See http://ant.apache.org/manual/javacprops.html#target
I think it makes clear with the namespace, as we can create our own attributes and if the user specified attribute is the same as the Android one it avoid the conflict of the namespace.
You are importing from package "sub". start.py
is not itself in a package even if there is a __init__.py
present.
You would need to start your program from one directory over parent.py
:
./start.py
./pkg/__init__.py
./pkg/parent.py
./pkg/sub/__init__.py
./pkg/sub/relative.py
With start.py
:
import pkg.sub.relative
Now pkg is the top level package and your relative import should work.
If you want to stick with your current layout you can just use import parent
. Because you use start.py
to launch your interpreter, the directory where start.py
is located is in your python path. parent.py
lives there as a separate module.
You can also safely delete the top level __init__.py
, if you don't import anything into a script further up the directory tree.
use the float or real data types only if the precision provided by decimal (up to 38 digits) is insufficient
Approximate numeric data types do not store the exact values specified for many numbers; they store an extremely close approximation of the value.(Technet)
Avoid using float or real columns in WHERE clause search conditions, especially the = and <> operators (Technet)
so generally because the precision provided by decimal is [10E38 ~ 38 digits] if your number can fit in it, and smaller storage space (and maybe speed) of Float is not important and dealing with abnormal behaviors and issues of approximate numeric types are not acceptable, use Decimal generally.
