There is no variable included for that yet, so you have to use shell-out-read-file method:
sh 'pwd > workspace'
workspace = readFile('workspace').trim()
Or (if running on master node):
workspace = pwd()

I have Java 7 and Java 6 installed, I need to run some builds with 6, others with 7. Therefore I need to dynamically alter JAVA_HOME
so that maven picks up what I want for each build. I did the following:
j6.sh
script which simply does export JAVA_HOME=...
path to j6 install...j6.sh
in that respective command terminal. By default, my JAVA_HOME
is set to J7.Hope this helps.

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u
prefix on strings, i.e. u'€'
or by decoding a string with mystr.decode('utf-8')
using the appropriate encoding.
The best practice is to decode all text data as it's read, rather than decoding mid-program. The io
module provides an open()
method which decodes text data to Unicode strings as it's read.
ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write()
method.
Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write()
and adds the relevant header.
Presuming your input file is UTF-8 encoded (0xC2
is common UTF-8 lead byte), putting everything together, and using the with
statement, your code should look like:
with io.open('myText.txt', "r", encoding='utf-8') as f:
data = f.read()
root = ET.Element("add")
doc = ET.SubElement(root, "doc")
field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data
tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)
Output:
<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>
One way is to stack the frames on top of each other, then you can simply raise one above the other in the stacking order. The one on top will be the one that is visible. This works best if all the frames are the same size, but with a little work you can get it to work with any sized frames.
Note: for this to work, all of the widgets for a page must have that page (ie: self
) or a descendant as a parent (or master, depending on the terminology you prefer).
Here's a bit of a contrived example to show you the general concept:
try:
import tkinter as tk # python 3
from tkinter import font as tkfont # python 3
except ImportError:
import Tkinter as tk # python 2
import tkFont as tkfont # python 2
class SampleApp(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")
# the container is where we'll stack a bunch of frames
# on top of each other, then the one we want visible
# will be raised above the others
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, PageOne, PageTwo):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
# put all of the pages in the same location;
# the one on the top of the stacking order
# will be the one that is visible.
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("StartPage")
def show_frame(self, page_name):
'''Show a frame for the given page name'''
frame = self.frames[page_name]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is the start page", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button1 = tk.Button(self, text="Go to Page One",
command=lambda: controller.show_frame("PageOne"))
button2 = tk.Button(self, text="Go to Page Two",
command=lambda: controller.show_frame("PageTwo"))
button1.pack()
button2.pack()
class PageOne(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is page 1", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button = tk.Button(self, text="Go to the start page",
command=lambda: controller.show_frame("StartPage"))
button.pack()
class PageTwo(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="This is page 2", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button = tk.Button(self, text="Go to the start page",
command=lambda: controller.show_frame("StartPage"))
button.pack()
if __name__ == "__main__":
app = SampleApp()
app.mainloop()
If you find the concept of creating instance in a class confusing, or if different pages need different arguments during construction, you can explicitly call each class separately. The loop serves mainly to illustrate the point that each class is identical.
For example, to create the classes individually you can remove the loop (for F in (StartPage, ...)
with this:
self.frames["StartPage"] = StartPage(parent=container, controller=self)
self.frames["PageOne"] = PageOne(parent=container, controller=self)
self.frames["PageTwo"] = PageTwo(parent=container, controller=self)
self.frames["StartPage"].grid(row=0, column=0, sticky="nsew")
self.frames["PageOne"].grid(row=0, column=0, sticky="nsew")
self.frames["PageTwo"].grid(row=0, column=0, sticky="nsew")
Over time people have asked other questions using this code (or an online tutorial that copied this code) as a starting point. You might want to read the answers to these questions:
$limit = (Get-Date).AddDays(-15)
$path = "C:\Some\Path"
# Delete files older than the $limit.
Get-ChildItem -Path $path -Force | Where-Object { !$_.PSIsContainer -and $_.CreationTime -lt $limit } | Remove-Item -Force -Recurse
This will delete old folders and it content.

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.
Here's how to do it for Internet Explorer:
function copy (str)
{
//for IE ONLY!
window.clipboardData.setData('Text',str);
}
The documentation says
The output format of the date/time types can be set to one of the four styles ISO 8601, SQL (Ingres), traditional POSTGRES (Unix date format), or German. The default is the ISO format.
So this particular format can be controlled with postgres
date time output, eg:
t=# select now();
now
-------------------------------
2017-11-29 09:15:25.348342+00
(1 row)
t=# set datestyle to DMY, SQL;
SET
t=# select now();
now
-------------------------------
29/11/2017 09:15:31.28477 UTC
(1 row)
t=# select now()::date;
now
------------
29/11/2017
(1 row)
Mind that as @Craig mentioned in his answer, changing datestyle
will also (and in first turn) change the way postgres parses date.
It's easy to achieve this is to just use an Intent like this: (I put the method in a custom class that takes in an Activity as a parameter so it can be called from any Fragment or Activity)
public class UIutils {
private Activity mActivity;
public UIutils(Activity activity){
mActivity = activity;
}
public void showPhoto(Uri photoUri){
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(photoUri, "image/*");
mActivity.startActivity(intent);
}
}
Then to use it just do this:
imageView.setOnClickListener(v1 -> new UIutils(getActivity()).showPhoto(Uri.parse(imageURI)));
I use this with an Image URL but it can be used with stored files as well. If you are accessing images form the phones memory you should use a content provider.
Where possible, I prefer to call the function rather than dispatch an event. This works well if you have control over the code you want to run, but see below for cases where you don't own the code.
window.onresize = doALoadOfStuff;
function doALoadOfStuff() {
//do a load of stuff
}
In this example, you can call the doALoadOfStuff
function without dispatching an event.
In your modern browsers, you can trigger the event using:
window.dispatchEvent(new Event('resize'));
This doesn't work in Internet Explorer, where you'll have to do the longhand:
var resizeEvent = window.document.createEvent('UIEvents');
resizeEvent.initUIEvent('resize', true, false, window, 0);
window.dispatchEvent(resizeEvent);
jQuery has the trigger
method, which works like this:
$(window).trigger('resize');
And has the caveat:
Although
.trigger()
simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.
You can also simulate events on a specific element...
function simulateClick(id) {
var event = new MouseEvent('click', {
'view': window,
'bubbles': true,
'cancelable': true
});
var elem = document.getElementById(id);
return elem.dispatchEvent(event);
}
To Answer this in very short, this issue comes when your local has some information about the remote and someone changes something which makes remote and your changes unsync.
I was getting this issue because someone has deleted remote branch and again created with the same name.
For dealing with such issues, do a pull or fetch from remote.
git remote prune origin
or if you are using any GUI, do a fetch from remote.
This link (How to get line count cheaply in Python?) has lots of potential solutions, but they all ignore one way to make this run considerably faster, namely by using the unbuffered (raw) interface, using bytearrays, and doing your own buffering.
Using a modified version of the timing tool, I believe the following code is faster (and marginally more pythonic) than any of the solutions offered:
def _make_gen(reader):
b = reader(1024 * 1024)
while b:
yield b
b = reader(1024*1024)
def rawpycount(filename):
f = open(filename, 'rb')
f_gen = _make_gen(f.raw.read)
return sum( buf.count(b'\n') for buf in f_gen )
Here are my timings:
rawpycount 0.0048 0.0046 1.00
bufcount 0.0074 0.0066 1.43
wccount 0.01 0.01 2.17
itercount 0.014 0.014 3.04
opcount 0.021 0.02 4.43
kylecount 0.023 0.021 4.58
simplecount 0.022 0.022 4.81
mapcount 0.038 0.032 6.82
I would post it there, but I'm a relatively new user to stack exchange and don't have the requisite manna.
EDIT:
This can be done completely with generators expressions in-line using itertools, but it gets pretty weird looking:
from itertools import (takewhile,repeat)
def rawbigcount(filename):
f = open(filename, 'rb')
bufgen = takewhile(lambda x: x, (f.raw.read(1024*1024) for _ in repeat(None)))
return sum( buf.count(b'\n') for buf in bufgen if buf )
A jQuery solution:
$("#frame1").ready( function() {
$("#frame1").contents().scrollTop( $("#frame1").contents().scrollTop() + 10 );
});
In my case this was caused by a faulty deployment where a setting in my web.config was not made.
A collegue explained that the IP address in the error message represents the localhost.
When I corrected the web.config I was then using the correct url to make the server calls and it worked.
I thought I would post this in case it might help someone.
Here is a simple snippet that read's in a json
text file from a dictionary. Note that your json file must follow the json standard, so it has to have "
double quotes rather then '
single quotes.
Your JSON dump.txt File:
{"test":"1", "test2":123}
Python Script:
import json
with open('/your/path/to/a/dict/dump.txt') as handle:
dictdump = json.loads(handle.read())
foreach($shipmentarr as $index=>$val){
$additionalService = array();
foreach($additionalService[$index] as $key => $value) {
array_push($additionalService,$value);
}
}
Yes, in principe it is possible, but it doesn't come for free.
You need to create a StackTrace, and then you can have a look at the StackFrame's of the call stack.
?? The accepted answer (and others) are outdated!
delete
does not remove variables.
(It's only for removing a property from an object.)
The correct way to "unset" is to simply set the variable to null
. (source)
(This enables JavaScript's automatic processes to remove the
variable from memory.)
Example:
x = null;
Use of the delete
operator on a variable is deprecated since 2012, when all browsers implemented (automatic) mark-and-sweep garbage-collection. The process works by automatically determining when objects/variables become "unreachable" (deciding whether or not the code still requires them).
With JavaScript, in all modern browsers:
The delete
operator is only used to remove a property from an object;
it does not remove variables.
Unlike what common belief suggests (perhaps due to other programming languages like
delete
in C++), thedelete
operator has nothing to do with directly freeing memory. Memory management is done indirectly via breaking references. (source)
When using strict mode ('use strict';
, as opposed to regular/"sloppy mode") an attempt to delete a variable will throw an error and is not allowed. Normal variables in JavaScript can't be deleted using the delete
operator (source) (or any other way, as of 2021).
...alas, the only solution:
null
:var x; // ... x = null; // (x can now be garbage collected)
(source)
For methods: (I am not sure if this exactly what you want)
print_thrice.py
def private(method):
def methodist(string):
if __name__ == "__main__":
method(string)
return methodist
@private
def private_print3(string):
print(string * 3)
private_print3("Hello ") # output: Hello Hello Hello
other_file.py
from print_thrice import private_print3
private_print3("Hello From Another File? ") # no output
This is probably not a perfect solution, as you can still "see" and/or "call" the method. Regardless, it doesn't execute.

If you want to send a custom HTTP Header (not a SOAP Header) then you need to use the HttpWebRequest class the code would look like:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("Authorization", token);
You cannot add HTTP headers using the visual studio generated proxy, which can be a real pain.

Emitting handbuilt html like this is probably the best way so long as the markup isn't too complicated. The stringbuilder only starts to pay you back in terms of efficiency after about three concatenations, so for really simple stuff string + string will do.
Other than that you can start to use the html controls (System.Web.UI.HtmlControls) and render them, that way you can sometimes inherit them and make your own clasess for complex conditional layout.
You don't need to use the background animate plugin if you just use separate values like this:
$('.pop').animate({
'background-position-x': '10%',
'background-position-y': '20%'
}, 10000, 'linear');
Found this on HTML table: keep the same width for columns
If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your to and remove the inside of it, and then set fixed widths for the cells in .
In newer versions of react-router you want to wrap the routes in a Switch which only renders the first matched component. Otherwise you would see multiple components rendered.
For example:
import React from 'react';
import ReactDOM from 'react-dom';
import {
BrowserRouter as Router,
Route,
browserHistory,
Switch
} from 'react-router-dom';
import App from './app/App';
import Welcome from './app/Welcome';
import NotFound from './app/NotFound';
const Root = () => (
<Router history={browserHistory}>
<Switch>
<Route exact path="/" component={App}/>
<Route path="/welcome" component={Welcome}/>
<Route component={NotFound}/>
</Switch>
</Router>
);
ReactDOM.render(
<Root/>,
document.getElementById('root')
);

I just managed to wedge myself pretty thoroughly trying to follow user619330's advice above. The situation was: (1): I had added some files while working on my initial branch, branch1; (2) I created a new branch, branch2 for further development, branching it off from the trunk and then merging in my changes from branch1 (3) A co-worker had copied my mods from branch1 to his own branch, added further mods, and then merged back to the trunk; (4) I now wanted to merge the latest changes from trunk into my current working branch, branch2. This is with svn 1.6.17.
The merge had tree conflicts with the new files, and I wanted the new version from the trunk where they differed, so from a clean copy of branch2, I did an svn delete of the conflicting files, committed these branch2 changes (thus creating a temporary version of branch2 without the files in question), and then did my merge from the trunk. I did this because I wanted the history to match the trunk version so that I wouldn't have more problems later when trying to merge back to trunk. Merge went fine, I got the trunk version of the files, svn st shows all ok, and then I hit more tree conflicts while trying to commit the changes, between the delete I had done earlier and the add from the merge. Did an svn resolve of the conflicts in favor of my working copy (which now had the trunk version of the files), and got it to commit. All should be good, right?
Well, no. An update of another copy of branch2 resulted in the old version of the files (pre-trunk merge). So now I have two different working copies of branch2, supposedly updated to the same version, with two different versions of the files, and both insisting that they are fully up to date! Checking out a clean copy of branch2 resulted in the old (pre-trunk) version of the files. I manually update these to the trunk version and commit the changes, go back to my first working copy (from which I had submitted the trunk changes originally), try to update it, and now get a checksum error on the files in question. Blow the directory in question away, get a new version via update, and finally I have what should be a good version of branch2 with the trunk changes. I hope. Caveat developer.
/^[-\w\s]+$/
\w matches letters, digits, and underscores
\s matches spaces, tabs, and line breaks
- matches the hyphen (if you have hyphen in your character set example [a-z], be sure to place the hyphen at the beginning like so [-a-z])
Here's a funny answer.
You can declare a final one-element array and change the elements of the array all you want apparently. I'm sure it breaks the very reason why this compiler rule was implemented in the first place but it's handy when you're in a time-bind as I was today.
I actually can't claim credit for this one. It was IntelliJ's recommendation! Feels a bit hacky. But doesn't seem as bad as a global variable so I thought it worth mentioning here. It's just one solution to the problem. Not necessarily the best one.
final int[] tapCount = {0};
addSiteButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
tapCount[0]++;
}
});
A couple of quick extensions on what has already been said...
An id
must be unique, but you can use the same id to make different styles more specific.
For example, given this HTML extract:
<div id="sidebar">
<h2>Heading</h2>
<ul class="menu">
...
</ul>
</div>
<div id="content">
<h2>Heading</h2>
...
</div>
<div id="footer">
<ul class="menu">
...
</ul>
</div>
You could apply different styles with these:
#sidebar h2
{ ... }
#sidebar .menu
{ ... }
#content h2
{ ... }
#footer .menu
{ ... }
Another useful thing to know: you can have multiple classes on an element, by space-delimiting them...
<ul class="main menu">...</ul>
<ul class="other menu">...</ul>
Which allows you to have common styling in .menu
with specific styles using .main.menu
and .sub.menu
.menu
{ ... }
.main.menu
{ ... }
.other.menu
{ ... }
In case you're not in the specified directory (i.e. direct), you should use (in linux):
x_file = open('path/to/direct/filename.txt')
Note the quotes and the relative path to the directory.
This may be your problem, but you also don't have permission to access that file. Maybe you're trying to open it as another user.
You could disable the warnings temporarily in places where they appear by using
#pragma warning(push)
#pragma warning(disable: warning-code) //4996 for _CRT_SECURE_NO_WARNINGS equivalent
// deprecated code here
#pragma warning(pop)
so you don't disable all warnings, which can be harmful at times.
This worked for me using it in a toolstrip menu:
private void calculatorToolStripMenuItem_Click(object sender, EventArgs e)
{
calculator form = new calculator();
form.Show(); // or form.ShowDialog(this);
}
Try this out:
<script type="text/javascript">
function test
{
alert("hello world"); //write your logic here like ajax
}
</script>
<form action="javascript:test();" >
firstName : <input type="text" name="firstName" id="firstName" required/><br/>
lastName : <input type="text" name="lastName" id="lastName" required/><br/>
email : <input type="email" name="email" id="email"/><br/>
<input type="submit" value="Get It!" name="submit" id="submit"/>
</form>
Having just struggled with this - I'll explain my situation.
I have my tabs within a bootstrap modal and set the following on load (pre the modal being triggered):
$('#subMenu li:first-child a').tab('show');
Whilst the tab was selected the actual pane wasn't visible. As such you need to add active
class to the pane as well:
$('#profile').addClass('active');
In my case the pane had #profile
(but this could have easily been .pane:first-child
) which then displayed the correct pane.
I would try
Sheets("Sheet1").Activate
Set Ticker = Range(Cells(2, 1), Cells(65, 1))
Ticker.Copy
Worksheets("Sheet2").Range("A1").Offset(0,0).Cells.Select
Worksheets("Sheet2").paste
It's written down in the Fielding dissertation. But if you don't want to read a lot:
In Python2, input
is evaluated, input()
is equivalent to eval(raw_input())
. When you enter klj, Python tries to evaluate that name and raises an error because that name is not defined.
Use raw_input
to get a string from the user in Python2.
Demo 1: klj
is not defined:
>>> input()
klj
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1, in <module>
NameError: name 'klj' is not defined
Demo 2: klj
is defined:
>>> klj = 'hi'
>>> input()
klj
'hi'
Demo 3: getting a string with raw_input
:
>>> raw_input()
klj
'klj'
If you want to get the value of an integer for 2 raised to the power of something it is always better to use the shift option:
pow(2,5)
can be replaced by 1<<5
This is much more efficient.
If you are using an array (and purely an array), the lookup of "contains" is O(N)
, because worst case, you must iterate the entire array. Now if the array is sorted you can use a binary search, which reduces the search time to log(N)
with the overhead of the sort.
If this is something that is invoked repeatedly, place it in a function:
private boolean inArray(int[] array, int value)
{
for (int i = 0; i < array.length; i++)
{
if (array[i] == value)
{
return true;
}
}
return false;
}

add the library under COM object for window media player then type your code where you want

WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();
wplayer.URL = @"C:\Users\Adil M\Documents\Visual Studio 2012\adil.mp3";
wplayer.controls.play();
SQLDeveloper can do this.
I imagine that trygetvalue is doing something more like:
if(myDict.ReallyOptimisedVersionofContains(someKey))
{
someVal = myDict[someKey];
return true;
}
return false;
So hopefully no try/catch anywhere.
I think it is just a method of convenience really. I generally use it as it saves a line of code or two.
Perhaps you might want to try JSON.parse your return result first then you can get the count by .length
datetime.strptime
is the main routine for parsing strings into datetimes. It can handle all sorts of formats, with the format determined by a format string you give it:
from datetime import datetime
datetime_object = datetime.strptime('Jun 1 2005 1:33PM', '%b %d %Y %I:%M%p')
The resulting datetime
object is timezone-naive.
Links:
Python documentation for strptime
/strftime
format strings: Python 2, Python 3
strftime.org is also a really nice reference for strftime
Notes:
strptime
= "string parse time"strftime
= "string format time"$users = User::select('column1', 'column2', 'column3')->distinct()->get();
retrieves all three coulmns for distinct rows in the table. You can add as many columns as you wish.
You could use this script:
def run(runfile):
with open(runfile,"r") as rnf:
exec(rnf.read())
Syntax:

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()
):
entryList.forEach(e->e.setTempId(tempId));
List<Entry> updatedEntries = entryList.stream()
.map(e->entityManager.update(entry, entry.getId()))
.collect(toList());
Here's a short one:

And database.yml is place where you put setup for database your application use - username, password, host - for each database. With new application you dont need to change anything - simply use default sqlite setup.
The Barack Obama app took 22 days to develop from first code to release. Three developers (although not all of them were full time). 10 people total. Figure 500-1000 man hours. Contracting rates are $100-150/hr. Figure $50000-$150000. Compare your app to Obama.app and scale accordingly.
If you meant just ABC as simple value, answer above is the one that works fine.
If you meant concatenation of values of rows that are not selected by your main query, you will need to use a subquery.
Something like this may work:
SELECT t1.col1,
t1.col2,
(SELECT GROUP_CONCAT(col2 SEPARATOR '') FROM Table1 t2 WHERE t2.col1 != 0) as col3
FROM Table1 t1
WHERE t1.col1 = 0;
Actual syntax maybe a bit off though

select * from tbl where (endDate>=@starDate and startDate<=@endDate)
attached the diagram for explanation
storing simple data in DB StartDate =10/01/2020 and endDate=20/01/2020. user can provide @startDate(d1) and @endDate(d2) to search.
here 6 scenarios can happen depicted by the 4 red lines (match data) 2 green lines (no match data).
so by conclusion from the image, to get data from DB by providing d1,d2. ED must be greater than d1(@startDate) and SD must be less than d2(@endDate).

The trick here is that Controls
is not a List<>
or IEnumerable
but a ControlCollection
.
I recommend using an extension of Control that will return something more..queriyable ;)
public static IEnumerable<Control> All(this ControlCollection controls)
{
foreach (Control control in controls)
{
foreach (Control grandChild in control.Controls.All())
yield return grandChild;
yield return control;
}
}
Then you can do :
foreach(var textbox in this.Controls.All().OfType<TextBox>)
{
// Apply logic to the textbox here
}
They are serializable, have a zero-argument constructor, and allow access to properties using getter and setter methods. The name "Bean" was given to encompass this standard, which aims to create reusable software components for Java. According to Wikipedia.
The objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application. According to Spring IoC.
We managed installation of netbeans 6.8 under windows 8 successfully the following way:

Modern Jenkins versions (since 2.26, October 2016) solved this: it's just an advanced option for the Execute shell build step!
You can just choose and set an arbitrary exit value; if it matches, the build will be unstable. Just pick a value which is unlikely to be launched by a real process in your build.

What you are trying to do is an extension of string slicing in Python:
Say all strings are of length 10, last char to be removed:

'abcdefghi'
To remove last N
characters:
>>> N = 3
>>> st[:-N]

Go to SETTINGS->Location and Security-> Device Administrator and deselect the admin which you want to uninstall.
Now uninstall the application. If it still says you need to deactivate the application before uninstalling, you may need to Force Stop the application before uninstalling.
Your first one was basically right. This, FYI, is bad. It does an equality check between a DOM node and a string:
if (document.getElementById('customx') == ""){
DOM nodes are actually their own type of JavaScript object. Thus this comparison would never work at all since it's doing an equality comparison on two distinctly different data types.
You can use math.ceil()
to round up, and then multiply by 10
import math
def roundup(x):
return int(math.ceil(x / 10.0)) * 10

.mouseover()
.hover()
Bind one or two handlers
to the matched elements, to be executed when the mouse pointer
enters and leaves the elements.
Calling $(selector).hover(handlerIn, handlerOut)
is shorthand for:
$(selector).mouseenter(handlerIn).mouseleave(handlerOut);
Bind an event handler to be fired when the mouse enters an element, or trigger that handler on an element.
mouseover
fires when the pointer moves into the child element as
well, while mouseenter
fires only when the pointer moves into the
bound element.
Because of this, .mouseover()
is not the same as .hover()
, for the same reason .mouseover()
is not the same as .mouseenter()
.
$('selector').mouseover(over_function) // may fire multiple times
// enter and exit functions only called once per element per entry and exit
$('selector').hover(enter_function, exit_function)
I would recommend you having a look at the basics of conditioning in bash.
The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.
Usage:
elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)]
In short, edit your code segment to:
elif [ "$seconds" -gt 0 ]
You'd be fine with no compilation errors. Your final code segment should look like this:
#!/bin/sh
if [ "$seconds" -eq 0 ];then
$timezone_string="Z"
elif [ "$seconds" -gt 0 ]
then
$timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60`
else
echo "Unknown parameter"

The Java JNI requires OS libraries of the same "bittiness" as the JVM. If you attempt to build something that depends, for example, on IESHIMS.DLL (lives in %ProgramFiles%\Internet Explorer) you need to take the 32bit version when your JVM is 32bit, the 64bit version when your JVM is 64bit. Likewise for other platforms.
Apart from that, you should be all set. The generated Java bytecode s/b the same.
Note that you should use 64bit Java compiler for larger projects because it can address more memory.
I was getting this error on ubuntu but you can try with the following command:

You can create a new queue item to do your removing of the class:
$("#div").addClass("error").delay(1000).queue(function(next){
$(this).removeClass("error");
next();
});
Or using the dequeue method:
$("#div").addClass("error").delay(1000).queue(function(){
$(this).removeClass("error").dequeue();
});
The reason you need to call next
or dequeue
is to let jQuery know that you are done with this queued item and that it should move on to the next one.
Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.
From the javadoc about System
, here's what the doc says:
public final class System
extends Object
The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.
Since:
JDK1.0
Regarding System.out
public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:
System.out.println(data)
JRockit Mission Control is becoming Java Mission Control and will be dedicated exclusively to Hotspot. If you are an Oracle customer, you can download the 5.x versions of Java Mission Control from MOS (My Oracle Support). Java Mission Control will eventually be released together with the Oracle JDK. The reason it is not yet generally available is that there are some serious limitations, especially when using the Flight Recorder. However, if you are only interested in using the JMX console, you should be golden!
Using params
allows you to call the function with no arguments. Without params
:
static public int addTwoEach(int[] args)
{
int sum = 0;
foreach (var item in args)
{
sum += item + 2;
}
return sum;
}
addtwoEach(); // throws an error
Compare with params
:
static public int addTwoEach(params int[] args)
{
int sum = 0;
foreach (var item in args)
{
sum += item + 2;
}
return sum;
}
addtwoEach(); // returns 0
Generally, you can use params when the number of arguments can vary from 0 to infinity, and use an array when numbers of arguments vary from 1 to infinity.
Both proposed possibilities (std::swap
and std::iter_swap
) work, they just have a slightly different syntax.
Let's swap a vector's first and second element, v[0]
and v[1]
.
We can swap based on the objects contents:
std::swap(v[0],v[1]);
Or swap based on the underlying iterator:
std::iter_swap(v.begin(),v.begin()+1);
Try it:
int main() {
int arr[] = {1,2,3,4,5,6,7,8,9};
std::vector<int> * v = new std::vector<int>(arr, arr + sizeof(arr) / sizeof(arr[0]));
// put one of the above swap lines here
// ..
for (std::vector<int>::iterator i=v->begin(); i!=v->end(); i++)
std::cout << *i << " ";
std::cout << std::endl;
}
Both times you get the first two elements swapped:
2 1 3 4 5 6 7 8 9
If you don't want hashes and just the first lines (subject lines):
git log --pretty=format:%s
As of pandas 0.20.3, use .to_pydatetime()
to convert any pandas.DateTimeIndex
instances to Python datetime.datetime
.
new File(fileName).getName();
or
int idx = fileName.replaceAll("\\\\", "/").lastIndexOf("/");
return idx >= 0 ? fileName.substring(idx + 1) : fileName;
Notice that the first solution is system dependent. It only takes the system's path separator character into account. So if your code runs on a Unix system and receives a Windows path, it won't work. This is the case when processing file uploads being sent by Internet Explorer.

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".
Sub test()
dbWb = Application.ActiveWorkbook.FullName
dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2" 'Data2 is a named range
sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh
Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command
dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon
dbCommand.CommandText = sCommand
dbCommand.Execute
dbCon.Close
End Sub

++x increments the value of x and then returns x
x++ returns the value of x and then increments

x=0;
a=++x;
b=x++;
after the code is run both a and b will be 1 but x will be 2.
In Java an array has a fixed size (after initialisation), meaning that you can't add or remove items from an array.
int[] i = new int[10];
The above snippet mean that the array of integers has a length of 10. It's not possible add an eleventh integer, without re-assign the reference to a new array, like the following:
int[] i = new int[11];
In Java the package java.util contains all kinds of data structures that can handle adding and removing items from array-like collections. The classic data structure Stack has methods for push and pop.
UITableView
has a property separatorInset
. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.
[tableView setSeparatorInset:UIEdgeInsetsZero];
Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:
if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[tableView setSeparatorInset:UIEdgeInsetsZero];
}

I'm using the change-case extension and it works fine. I defined the shortcuts:
{

"command": "extension.changeCase.upper",
"when": "editorTextFocus"
},
{
"key": "ctrl+u",
"command": "extension.changeCase.lower",
"when": "editorTextFocus"

I did this on my Windows 7 computer today:
$('form').serialize() //this produces: "foo=1&bar=xxx&this=hi"
An alternative to using a plugin is using an editor template. What you need to do is to create a template file in Shared\EditorTemplates
folder and call it String.cshtml
. Then put this in that file:
@Html.TextBox("",ViewData.TemplateInfo.FormattedModelValue,
new { placeholder = ViewData.ModelMetadata.Watermark })
Then use it in your view like this:
@Html.EditorFor(m=>Model.UnitPercent)
The downside, this works for properties of type string
, and you will have to create a template for each type
that you want support for a watermark.
It's not clear to me exactly where the high-score that you're interested in is stored, but the code below should be what you need to check if the file exists and append to it if desired. I prefer this method to the "try/except".
import os
player = 'bob'
filename = player+'.txt'
if os.path.exists(filename):
append_write = 'a' # append if already exists
else:
append_write = 'w' # make a new file if not
highscore = open(filename,append_write)
highscore.write("Username: " + player + '\n')
highscore.close()
You can change your UI culture to anything you want, but you should change the number separator like this:
CultureInfo info = new CultureInfo("fa-IR");
info.NumberFormat.NumberDecimalSeparator = ".";
Thread.CurrentThread.CurrentCulture = info;
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
With this, your strings converts like this: "12.49" instead of "12,49" or "12/49"
This is way more simpler with Maven dependency feature:
Hope this will help!
It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.
<input id="myFileInput" type="file" accept="image/*;capture=camera">
var myInput = document.getElementById('myFileInput');
function sendPic() {
var file = myInput.files[0];
// Send file here either by adding it to a `FormData` object
// and sending that via XHR, or by simply passing the file into
// the `send` method of an XHR instance.
}
myInput.addEventListener('change', sendPic, false);
I'd say don't use angular/js as you can simply use css instead:
In your css, add the class:
.capitalize {
text-transform: capitalize;
}
Then, simply wrap the expression (for ex) in your html:
<span class="capitalize">{{ uppercase_expression }}</span>
No js needed ;)
For Java, I highly recommend Core Java. It's a large tome (or two large tomes), but I've found it to be one of the best references on Java I've read.
This is a first step for somebody that is a beginner. Same thing happened to me:
Look in the Solution Explorer box to the left. Make sure that there is actually a .cpp
file there. You can do the same by looking the .cpp
file where the .sln
file for the project is stored. If there is not one, then you will get that error.
When adding a cpp file you want to use the Add new item icon. (top left with a gold star on it, hover over it to see the name) For some reason Ctrl+N does not actually add a .cpp
file to the project.
If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.
Ex.
Filename: csvsample.php
class csvsample {
}
Strangely, no one answered the bottom part of the question for years even though this is an important one -- data.frame
s are simply lists with the right attributes, so if you have large data you don't want to use as.data.frame
or similar for a list. It's much faster to simply "turn" a list into a data frame in-place:
attr(df, "row.names") <- .set_row_names(length(df[[1]]))
class(df) <- "data.frame"
This makes no copy of the data so it's immediate (unlike all other methods). It assumes that you have already set names()
on the list accordingly.
[As for loading large data into R -- personally, I dump them by column into binary files and use readBin()
- that is by far the fastest method (other than mmapping) and is only limited by the disk speed. Parsing ASCII files is inherently slow (even in C) compared to binary data.]
These methods works on the locks and locks are associated with Object and not Threads. Hence, it is in Object class.
The methods wait(), notify() and notifyAll() are not only just methods, these are synchronization utility and used in communication mechanism among threads in Java.

If you wish to change the default configurations then follow this steps:
Open terminal type command
$ /usr/local/lib/python<2/3>.x/dist-packages/django/core/management/commands
Now open runserver.py file in nano editor as superuser
$ sudo nano runserver.py
find the 'default_port' variable then you will see the default port no is '8000'. Now you can change it to whatever you want.
Now exit and save the file using "CTRL + X and Y to save the file"
Note: Replace <2/3>.x with your usable version of python
For username and password protected services use the following
curl -u admin:password -X GET http://172.16.2.125:9200 -d '{"sort":[{"lastUpdateTime":{"order":"desc"}}]}'
This will get ALL parameters from the request. For Debugging purposes only:
@RequestMapping (value = "/promote", method = {RequestMethod.POST, RequestMethod.GET})
public ModelAndView renderPromotePage (HttpServletRequest request) {
Map<String, String[]> parameters = request.getParameterMap();
for(String key : parameters.keySet()) {
System.out.println(key);
String[] vals = parameters.get(key);
for(String val : vals)
System.out.println(" -> " + val);
}
ModelAndView mv = new ModelAndView();
mv.setViewName("test");
return mv;
}
if you are using windows try to pass encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' example:
csv_data = pd.read_csv(csvpath,encoding='iso-8859-1')
print(print(soup.encode('iso-8859-1')))
Having is only used with aggregation but where with non aggregation statements If you have where word put it before aggregation (group by)
You can also do something like this...

Main class need to be outside of your app packages tree structure. For example:
Its the Windows OS that make the problem. I got the same problem. Then I tried some other app which use JavaVM to connect the internet, and they fails. Try update JRE, you will notice it. If JRE cannot update itself, then there is some socket inaccessibility that prevent internet access apart from using native windows API. I reinstall Win7 and it fixed the problem.
To split into more than two classes such as train, test, and validation, one can do:
probs = np.random.rand(len(df))
training_mask = probs < 0.7
test_mask = (probs>=0.7) & (probs < 0.85)
validatoin_mask = probs >= 0.85
df_training = df[training_mask]
df_test = df[test_mask]
df_validation = df[validatoin_mask]
This will put approximately 70% of data in training, 15% in test, and 15% in validation.
They have no keywords before them. The order is important!
func(1,2,3, "foo")
They have keywords in the front. They can be in any order!
func(foo="bar", baz=5, hello=123)
func(baz=5, foo="bar", hello=123)
You should also know that if you use default arguments and neglect to insert the keywords, then the order will then matter!
def func(foo=1, baz=2, hello=3): ...
func("bar", 5, 123)
The solution to the problem is:
Find the .gitconfig file
[user] name = 1wQasdTeedFrsweXcs234saS56Scxs5423 email = [email protected] [credential] helper = osxkeychain [url ""] insteadOf = git:// [url "https://"] [url "https://"] insteadOf = git://
there would be a blank url="" replace it with url="https://"
[user]
name = 1wQasdTeedFrsweXcs234saS56Scxs5423
email = [email protected]
[credential]
helper = osxkeychain
[url "https://"]
insteadOf = git://
[url "https://"]
[url "https://"]
insteadOf = git://
This will work :)
Happy Bower-ing
For committing, I use the following strategies:
commit as often as possible.
Each feature change/bugfix should get its own commit (don't commit many files at once since that will make the history for that file unclear -- e.g. If I change a logging module and a GUI module independently and I commit both at once, both changes will be visible in both file histories. This makes reading a file history difficult),
don't break the build on any commit -- it should be possible to retrieve any version of the repository and build it.
All files that are necessary for building and running the app should be in SVN. Test files and such should not, unless they are part of the unit tests.
I am facing a similar problem here. Our users are migrating their jobs from freestyle to pipeline. They do not want Jenkinsfile stored in their repos(historical reason) and still want to use "Git Parameter" plugin
So we have to use use "Pipeline script" and develop a different plugin which works like "Git Parameter".
This new plugin does not integrate with SCM setting in the project. The plugin is at https://plugins.jenkins.io/list-git-branches-parameter
Hope it helps you as well
Use DecimalFormat
double answer = 5.0;
DecimalFormat df = new DecimalFormat("###.#");
System.out.println(df.format(answer));
Use sprintf()
:
int someInt = 368;
char str[12];
sprintf(str, "%d", someInt);
All numbers that are representable by int
will fit in a 12-char-array without overflow, unless your compiler is somehow using more than 32-bits for int
. When using numbers with greater bitsize, e.g. long
with most 64-bit compilers, you need to increase the array size—at least 21 characters for 64-bit types.
I know the OP was originally sending a single string, but for future reference, it is also worth noting that malformed JSON will also arrive as null
into the post method. In my case, a missing comma between two properties caused what was otherwise fine, to break.
You can also pass git reset --hard
a commit reference.
For example:
git checkout branch-name
git reset --hard new-tip-commit
I find I do something like this semi-frequently:
Assuming this history
$ git log --decorate --oneline --graph
* 3daed46 (HEAD, master) New thing I shouldn't have committed to master
* a0d9687 This is the commit that I actually want to be master
# Backup my latest commit to a wip branch
$ git branch wip_doing_stuff
# Ditch that commit on this branch
$ git reset --hard HEAD^
# Now my changes are in a new branch
$ git log --decorate --oneline --graph
* 3daed46 (wip_doing_stuff) New thing I shouldn't have committed to master
* a0d9687 (HEAD, master) This is the commit that I actually want to be master
cvWaitKey(0)
stops your program until you press a button.
cvWaitKey(10)
doesn't stop your program but wake up and alert to end your program when you press a button. Its used into loops because cvWaitkey
doesn't stop loop.
Normal use
char k;
k=cvWaitKey(0);
if(k == 'ESC')
with k
you can see what key was pressed.
Do this: Step 1: Your String
String str = ";;;;;;\n" +
"Name, number, address;;;;;;\n" +
"01.01.12-16.02.12;;;;;;\n" +
";;;;;;\n" +
";;;;;;";
Step 2: Just replace all "\n" with "%n" the result looks like this
String str = ";;;;;;%n" +
"Name, number, address;;;;;;%n" +
"01.01.12-16.02.12;;;;;;%n" +
";;;;;;%n" +
";;;;;;";
Notice I've just put "%n" in place of "\n"
Step 3: Now simply call format()
str=String.format(str);
That's all you have to do.
You can use the casting operators:
$myText = (string)$myVar;
There are more details for string casting and conversion in the Strings section of the PHP manual, including special handling for booleans and nulls.
I use props
and variables computed
properties if I need create logic after to receive the changes
export default {

}
},
computed: {
_objectDetail: {
let value = false
...
if (someValidation)
...
}
}
For python2/3, Using below code snippet we can activate virtual env.
activate_this = "/home/<--path-->/<--virtual env name -->/bin/activate_this.py" #for ubuntu
activate_this = "D:\<-- path -->\<--virtual env name -->\Scripts\\activate_this.py" #for windows
with open(activate_this) as f:
code = compile(f.read(), activate_this, 'exec')
exec(code, dict(__file__=activate_this))
For those looking for an SCSS mixin instead, including woff2:
@mixin fface($path, $family, $type: '', $weight: 400, $svg: '', $style: normal) {
@font-face {
font-family: $family;
@if $svg == '' {
// with OTF without SVG and EOT
src: url('#{$path}#{$type}.otf') format('opentype'), url('#{$path}#{$type}.woff2') format('woff2'), url('#{$path}#{$type}.woff') format('woff'), url('#{$path}#{$type}.ttf') format('truetype');
} @else {
// traditional src inclusions
src: url('#{$path}#{$type}.eot');
src: url('#{$path}#{$type}.eot?#iefix') format('embedded-opentype'), url('#{$path}#{$type}.woff2') format('woff2'), url('#{$path}#{$type}.woff') format('woff'), url('#{$path}#{$type}.ttf') format('truetype'), url('#{$path}#{$type}.svg##{$svg}') format('svg');
}
font-weight: $weight;
font-style: $style;
}
}
// ========================================================importing
$dir: '/assets/fonts/';
$famatic: 'AmaticSC';
@include fface('#{$dir}amatic-sc-v11-latin-regular', $famatic, '', 400, $famatic);
$finter: 'Inter';
// adding specific types of font-weights
@include fface('#{$dir}#{$finter}', $finter, '-Thin-BETA', 100);
@include fface('#{$dir}#{$finter}', $finter, '-Regular', 400);
@include fface('#{$dir}#{$finter}', $finter, '-Medium', 500);
@include fface('#{$dir}#{$finter}', $finter, '-Bold', 700);
// ========================================================usage
.title {
font-family: Inter;
font-weight: 700; // Inter-Bold font is loaded
}
.special-title {
font-family: AmaticSC;
font-weight: 700; // default font is loaded
}
The $type
parameter is useful for stacking related families with different weights.
The @if
is due to the need of supporting the Inter font (similar to Roboto), which has OTF but doesn't have SVG and EOT types at this time.
If you get a can't resolve error, remember to double check your fonts directory ($dir
).
A simular answer but i made it so you don't have to specify the type of returned pointer (note that the generic version requires C++20):
#include <iostream>
template<typename Function>
struct function_traits;
template <typename Ret, typename... Args>
struct function_traits<Ret(Args...)> {
typedef Ret(*ptr)(Args...);
};
template <typename Ret, typename... Args>
struct function_traits<Ret(*const)(Args...)> : function_traits<Ret(Args...)> {};
template <typename Cls, typename Ret, typename... Args>
struct function_traits<Ret(Cls::*)(Args...) const> : function_traits<Ret(Args...)> {};
using voidfun = void(*)();
template <typename F>
voidfun lambda_to_void_function(F lambda) {
static auto lambda_copy = lambda;
return []() {
lambda_copy();
};
}
// requires C++20
template <typename F>
auto lambda_to_pointer(F lambda) -> typename function_traits<decltype(&F::operator())>::ptr {
static auto lambda_copy = lambda;
return []<typename... Args>(Args... args) {
return lambda_copy(args...);
};
}
int main() {
int num;
void(*foo)() = lambda_to_void_function([&num]() {
num = 1234;
});
foo();
std::cout << num << std::endl; // 1234
int(*bar)(int) = lambda_to_pointer([&](int a) -> int {
num = a;
return a;
});
std::cout << bar(4321) << std::endl; // 4321
std::cout << num << std::endl; // 4321
}
In the Solution Explorer, right-click any ASPX page and select "Browse With" and select IE as the default.
Note... the same steps can be used to add Google Chrome as a browser option and to optionally set it as the default browser.
Had this issue with ES6 and TypeORM while trying to pass .where("order.id IN (:orders)", { orders })
, where orders
was a comma separated string of numbers. When I converted to a template literal, the problem was resolved.
.where(`order.id IN (${orders})`);
To get screen resolution in JS use screen
object
screen.height;
screen.width;
Based on that values you can calculate your margin to whatever suits you.
Date.parse()
isn't a constructor, its a static method.
So, just use
var timeInMillis = Date.parse(s);
instead of
var timeInMillis = new Date.parse(s);
you'd better reference angular document, becuase the version[1.4.9] has update to below that make it could support data-ng-cloak directive.
[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
display: none !important;
}
For folks using Python 3.0+ (which should be everyone now):
Unfortunately, MySQL-Python 1.2.5 does not support Python 3.0+ yet (which is kinda unreasonable IMHO, Python 3+ has been out for a while). Reference : https://pypi.python.org/pypi/MySQL-python/1.2.5
So, my workaround is to use Oracle's MySQL connector. In settings.py, change DATABASE's 'ENGINE' field to: 'ENGINE': 'mysql.connector.django',
More info could be found in the last paragraph of the first answer to this question: Setting Django up to use MySQL
Hope this helps!!
you might want to use force with push operation in this case
git push origin master --force
Based on above answers I created the following API
/*
* .addClassSVG(className)
* Adds the specified class(es) to each of the set of matched SVG elements.
*/
$.fn.addClassSVG = function(className){
$(this).attr('class', function(index, existingClassNames) {
return ((existingClassNames !== undefined) ? (existingClassNames + ' ') : '') + className;
});
return this;
};
/*
* .removeClassSVG(className)
* Removes the specified class to each of the set of matched SVG elements.
*/
$.fn.removeClassSVG = function(className){
$(this).attr('class', function(index, existingClassNames) {
var re = new RegExp('\\b' + className + '\\b', 'g');
return existingClassNames.replace(re, '');
});
return this;
};
I got the following example here
/*
7) Join Strings using separator >>>AB$#$CD$#$EF
*/
import org.apache.commons.lang.StringUtils;
public class StringUtilsTrial {
public static void main(String[] args) {
// Join all Strings in the Array into a Single String, separated by $#$
System.out.println("7) Join Strings using separator >>>"
+ StringUtils.join(new String[] { "AB", "CD", "EF" }, "$#$"));
}
}
for jQuery
we can use below:
by input name:
$('input[name="textboxname"]').val('some value');
by input class:
$('input[type=text].textboxclass').val('some value');
by input id:
$('#textboxid').val('some value');
data = pd.DataFrame({"a":[1,2,3,34],"b":[5,6,7,8]})
new_data = pd.melt(data)
new_data.set_index("variable", inplace=True)
This gives a dataframe with index as column name of data and all data are present in "values" column
There are jQuery-plugins that help you achieve this like: http://ricostacruz.com/jquery.transit/
Other answers are old, could not get a good answer.
Below example is for object literals, helps how both can complement each other, and how it cannot complement each other (therefore difference):
var obj1 = { a: 1, b: { b1: 1, b2: 'b2value', b3: 'b3value' } };
// overwrite parts of b key
var obj2 = {
b: {
...obj1.b,
b1: 2
}
};
var res2 = Object.assign({}, obj1, obj2); // b2,b3 keys still exist
document.write('res2: ', JSON.stringify (res2), '<br>');
// Output:
// res2: {"a":1,"b":{"b1":2,"b2":"b2value","b3":"b3value"}} // NOTE: b2,b3 still exists
// overwrite whole of b key
var obj3 = {
b: {
b1: 2
}
};
var res3 = Object.assign({}, obj1, obj3); // b2,b3 keys are lost
document.write('res3: ', JSON.stringify (res3), '<br>');
// Output:
// res3: {"a":1,"b":{"b1":2}} // NOTE: b2,b3 values are lost
Several more small examples here, also for array & object:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax
$('#mySelect')
.empty()
.append('<option value="whatever">text</option>')
.find('option:first')
.attr("selected","selected")
;
The use
operator is for giving aliases to names of classes, interfaces or other namespaces. Most use
statements refer to a namespace or class that you'd like to shorten:
use My\Full\Namespace;
is equivalent to:
use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo
If the use
operator is used with a class or interface name, it has the following uses:
// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;
// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;
The use
operator is not to be confused with autoloading. A class is autoloaded (negating the need for include
) by registering an autoloader (e.g. with spl_autoload_register
). You might want to read PSR-4 to see a suitable autoloader implementation.
All answers here are still using the FormData API. It is like a "multipart/form-data"
upload without a form. You can also upload the file directly as content inside the body of the POST
request using xmlHttpRequest
like this:
var xmlHttpRequest = new XMLHttpRequest();
var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...
xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);
Content-Type
and Content-Disposition
headers are used for explaining what we are sending (mime-type and file name).
I posted similar answer also here.
You can display all image from a folder using simple php script. Suppose folder name “images” and put some image in this folder and then use any text editor and paste this code and run this script. This is php code
<?php
$files = glob("images/*.*");
for ($i=0; $i<count($files); $i++)
{
$image = $files[$i];
$supported_file = array(
'gif',
'jpg',
'jpeg',
'png'
);
$ext = strtolower(pathinfo($image, PATHINFO_EXTENSION));
if (in_array($ext, $supported_file)) {
echo basename($image)."<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
echo '<img src="'.$image .'" alt="Random image" />'."<br /><br />";
} else {
continue;
}
}
?>
if you do not check image type then use this code
<?php
$files = glob("images/*.*");
for ($i = 0; $i < count($files); $i++) {
$image = $files[$i];
echo basename($image) . "<br />"; // show only image name if you want to show full path then use this code // echo $image."<br />";
echo '<img src="' . $image . '" alt="Random image" />' . "<br /><br />";
}
?>
Headers included with #include <> will be searched in all default directories , but you can also add your own location in the search path with -I command line arg.
I saw your edit you could install your headers in default locations usually
/usr/local/include
libdir/gcc/target/version/include
/usr/target/include
/usr/include
Confirm with compiler docs though.
Have you checked this http://support.microsoft.com/kb/209805? In particular, whether you have Msrd3x40.dll.
You may also like to check that you have the latest version of Jet: http://support.microsoft.com/kb/239114
This, from the masters themselves (K&R, 2nd ed., pg. 106):
// strcmp: return < 0 if s < t, 0 if s == t, > 0 if s > t
int strcmp(char *s, char *t)
{
int i;
for (i = 0; s[i] == t[i]; i++)
if (s[i] == '\0')
return 0;
return s[i] - t[i];
}
A useful trick to avoid creating temporary patch files:
git diff | patch -p1 -d [dst-dir]
create schema tableName authorization dbo
go
IF OBJECT_ID ('tableName.put_fieldValue', 'P' ) IS NOT NULL
drop proc tableName.put_fieldValue
go
create proc tableName.put_fieldValue(@fieldValue int) as
declare @tableid int = 0
select @tableid = tableid from table where fieldValue=''
if @tableid = 0 begin
insert into table(fieldValue) values('')
select @tableid = scope_identity()
end
return @tableid
go
declare @tablid int = 0
exec @tableid = tableName.put_fieldValue('')
Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder.
The opposite is a much better strategy. If you have minSdkVersion
to 14 and upload your apk to the play store, you'll notice you'll support the same number of devices whether you support armeabi
or not. Therefore, there are no devices with Android 4 or higher which would benefit from armeabi
at all.
This is probably why the Android NDK doesn't even support armeabi
anymore as per revision r17b. [source]
If you are going to follow the examples given (using getter/setter or setting it in the constructor) change it to private since those are ways to control what is set in the variable.
It doesn't make sense to keep the property public with all those things added to the class.
Just use good old HTML:
<input type="button" value="Submit" />
Wrap it as the subject of a link, if you so desire:
<a href="http://somewhere.com"><input type="button" value="Submit" /></a>
Or if you decide you want javascript to provide some other functionality:
<input type="button" value="Cancel" onclick="javascript: someFunctionThatCouldIncludeRedirect();"/>
SQL Server provides a built-in stored procedure that you can run to easily show the size of a table, including the size of the indexes… which might surprise you.
Syntax:
sp_spaceused 'Tablename'

Be careful, you're unwittingly asking "where the date is greater than one divided by nine, divided by two thousand and eight".
Put #
signs around the date, like this #1/09/2008#
The methodNotAllowed
exception indicates that a route doesn't exist for the HTTP method you are requesting.
Your form is set up to make a DELETE
request, so your route needs to use Route::delete()
to receive this.
Route::delete('empresas/eliminar/{id}', [
'as' => 'companiesDelete',
'uses' => 'CompaniesController@delete'
]);
string s = "THIS IS MY TEXT RIGHT NOW";
s = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());
and then execute in command prompt (ADMIN)
netsh wlan start hostednetwork
this worked for me:
text-align: center;
text-align-last: center;
I suspect the condition you are looking for is DUP_VAL_ON_INDEX

If you're using SASS in your project, I've built this mixin to make it work the way we all want it to:
@mixin not($ignorList...) {
//if only a single value given
@if (length($ignorList) == 1){
//it is probably a list variable so set ignore list to the variable
$ignorList: nth($ignorList,1);
}
//set up an empty $notOutput variable
$notOutput: '';
//for each item in the list
@each $not in $ignorList {
//generate a :not([ignored_item]) segment for each item in the ignore list and put them back to back
$notOutput: $notOutput + ':not(#{$not})';
}
//output the full :not() rule including all ignored items
&#{$notOutput} {
@content;
}
}
it can be used in 2 ways:
Option 1: list the ignored items inline
input {
/*non-ignored styling goes here*/
@include not('[type="radio"]','[type="checkbox"]'){
/*ignored styling goes here*/
}
}
Option 2: list the ignored items in a variable first
$ignoredItems:
'[type="radio"]',
'[type="checkbox"]'
;
input {
/*non-ignored styling goes here*/
@include not($ignoredItems){
/*ignored styling goes here*/
}
}
Outputted CSS for either option
input {
/*non-ignored styling goes here*/
}
input:not([type="radio"]):not([type="checkbox"]) {
/*ignored styling goes here*/
}
Not only does it not get executed, it doesn't even get compiled.
#if
is a preprocessor command, which gets evaluated before the actual compilation step. The code inside that block doesn't appear in the compiled binary.
It's often used for temporarily removing segments of code with the intention of turning them back on later.
That CSS goes from this file "tab-focus.less" in mixins folder (it could be difficult to find, because mixins are not shown at chrome dev-tools). So you should edit this:
// WebKit-style focus
.tab-focus() {
// Default
outline: thin dotted;
// WebKit
outline: 5px auto -webkit-focus-ring-color;
outline-offset: -2px;
}
Use (fast and simple):
df = df[np.isfinite(df).all(1)]
This answer is based on DougR's answer in an other question. Here an example code:

df=pd.DataFrame([1,2,3,np.nan,4,np.inf,5,-np.inf,6])
print('Input:\n',df,sep='')
df = df[np.isfinite(df).all(1)]
print('\nDropped:\n',df,sep='')
Result:
Input:

1 2.0000
2 3.0000
3 NaN
4 4.0000
5 inf

You need to put variable definition in the ~/.bashrc
file.
From bash man page:
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist.
Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit
<div ng-repeat="day in forecast_days" ng-init="f = forecast[day.iso]">
{{$index}} - {{day.iso}} - {{day.name}}
Temperature: {{f.temperature}}<br>
Humidity: {{f.humidity}}<br>
...
</div>

I wanted to add more details about how the @Valid
works, especially in spring.
Everything you'd want to know about validation in spring is explained clearly and in detail in https://reflectoring.io/bean-validation-with-spring-boot/, but I'll copy the answer to how @Valid
works incase the link goes down.
The @Valid
annotation can be added to variables in a rest controller method to validate them. There are 3 types of variables that can be validated:
So now... how does spring "validate"? You can define constraints to the fields of a class by annotating them with certain annotations. Then, you pass an object of that class into a Validator which checks if the constraints are satisfied.
For example, suppose I had controller method like this:
@RestController
class ValidateRequestBodyController {
@PostMapping("/validateBody")
ResponseEntity<String> validateBody(@Valid @RequestBody Input input) {
return ResponseEntity.ok("valid");
}
}
So this is a POST request which takes in a response body, and we're mapping that response body to a class Input
.
Here's the class Input
:
class Input {
@Min(1)
@Max(10)
private int numberBetweenOneAndTen;
@Pattern(regexp = "^[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}$")
private String ipAddress;
// ...
}
The @Valid annotation will tell spring to go and validate the data passed into the controller by checking to see that the integer numberBetweenOneAndTen
is between 1 and 10 inclusive because of those min and max annotations. It'll also check to make sure the ip address passed in matches the regular expression in the annotation.
side note: the regular expression isn't perfect.. you could pass in 3 digit numbers that are greater than 255 and it would still match the regular expression.
Here's an example of validating a query variable and path variable:
@RestController
@Validated
class ValidateParametersController {
@GetMapping("/validatePathVariable/{id}")
ResponseEntity<String> validatePathVariable(
@PathVariable("id") @Min(5) int id) {
return ResponseEntity.ok("valid");
}
@GetMapping("/validateRequestParameter")
ResponseEntity<String> validateRequestParameter(
@RequestParam("param") @Min(5) int param) {
return ResponseEntity.ok("valid");
}
}
In this case, since the query variable and path variable are just integers instead of just complex classes, we put the constraint annotation @Min(5)
right on the parameter instead of using @Valid
.
var desired = stringToReplace.replace(/[^\w\s]/gi, '')
As was mentioned in the comments it's easier to do this as a whitelist - replace the characters which aren't in your safelist.
The caret (^
) character is the negation of the set [...]
, gi
say global and case-insensitive (the latter is a bit redundant but I wanted to mention it) and the safelist in this example is digits, word characters, underscores (\w
) and whitespace (\s
).
You can also use CURRENT_TIMESTAMP
, if you feel like being more ANSI compliant (though if you're porting code between database vendors, that'll be the least of your worries). It's exactly the same as GetDate()
under the covers (see this question for more on that).
There's no ANSI equivalent for GetUTCDate()
, however, which is probably the one you should be using if your app operates in more than a single time zone ...
Use phpinfo()
and check the session.*
settings.
Maybe the information is stored in cookies and your browser does not accept cookies, something like that.
Check that first and come back with the results.
You can also do a print_r($_SESSION);
to have a dump of this variable and see the content....
Regarding your phpinfo()
, is the session.save_path
a valid one? Does your web server have write access to this directory?
Hope this helps.
I just had to deal with this issue. @user3445140's answer helped me, but was much more than I needed to do.

I've found that you can move div elements to the next line simply by setting the property
Display: block;
On each div.
Repository.addorupdate(entity, entity.id);
Repository.savechanges();
Var id = entity.id;
This will work.
It is globally method for rounded border of UIButton
class func setRoundedBorderButton(btn:UIButton)
{
btn.layer.cornerRadius = btn.frame.size.height/2
btn.layer.borderWidth = 0.5
btn.layer.borderColor = UIColor.darkGray.cgColor
}
.selected-elementClass{
overflow-y:auto;
}
merged = map(names(first), ~c(first[[.x]], second[[.x]])
merged = set_names(merged, names(first))
Using purrr. Also solves the problem of your lists not being in order.
Make use of the zfill()
helper method to left-pad any string, integer or float with zeros; it's valid for both Python 2.x and Python 3.x.
Sample usage:
print str(1).zfill(3);
# Expected output: 001
Description:
When applied to a value, zfill()
returns a value left-padded with zeros when the length of the initial string value less than that of the applied width value, otherwise, the initial string value as is.
Syntax:
str(string).zfill(width)
# Where string represents a string, an integer or a float, and
# width, the desired length to left-pad.
System.currentTimeMillis()
does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date
instance to a string before using it. You can use DateFormat
s to convert Date
s to String
s in any timezone:
DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());
If you are limited to ES6, the best option is Promise all. Promise.all(array)
also returns an array of promises after successfully executing all the promises in array
argument.
Suppose, if you want to update many student records in the database, the following code demonstrates the concept of Promise.all in such case-
let promises = students.map((student, index) => {
//where students is a db object
student.rollNo = index + 1;
student.city = 'City Name';
//Update whatever information on student you want
return student.save();
});
Promise.all(promises).then(() => {
//All the save queries will be executed when .then is executed
//You can do further operations here after as all update operations are completed now
});
Map is just an example method for loop. You can also use for
or forin
or forEach
loop. So the concept is pretty simple, start the loop in which you want to do bulk async operations. Push every such async operation statement in an array declared outside the scope of that loop. After the loop completes, execute the Promise all statement with the prepared array of such queries/promises as argument.
The basic concept is that the javascript loop is synchronous whereas database call is async and we use push method in loop that is also sync. So, the problem of asynchronous behavior doesn't occur inside the loop.
