it depends on your need, u can use either this.renderIcon()
or bind this.renderIcon.bind(this)
UPDATE
This is how you call a method outside the render.
buttonClick(){
console.log("came here")
}
render() {
return (
<div className="patient-container">
<button onClick={this.buttonClick.bind(this)}>Click me</button>
</div>
);
}
The recommended way is to write a separate component and import it.
All the solutions talk about adding the scroll on componentDidMount
or componentDidUpdate
but with the DOM.
I did all of that and didn't worked.
So, figured out some other way that works just fine for me.
Added
componentDidUpdate() { window.scrollTo(0, 0) }
on the header, that mine is out of the<Switch></Switch>
element. Just free in the app. Works.
I also found about some ScrollRestoration thing, but I'm lazy now. And for now going to keep it the "DidUpdate" way.
Give the same name in urls.py
path('detail/<int:id>', views.detail, name="detail"),
This is what I did.
Note: Please check App.js for the code.
If you liked it, you can drop a star.??
Update:
import * as htmlToImage from 'html-to-image';
import download from 'downloadjs';
import logo from './logo.svg';
import './App.css';
const App = () => {
const onButtonClick = () => {
var domElement = document.getElementById('my-node');
htmlToImage.toJpeg(domElement)
.then(function (dataUrl) {
console.log(dataUrl);
download(dataUrl, 'image.jpeg');
})
.catch(function (error) {
console.error('oops, something went wrong!', error);
});
};
return (
<div className="App" id="my-node">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<p>
Edit <code>src/App.js</code> and save to reload.

export default App;
Don't know if this is too late but you can use np.where to find the indices of non values as such:
indices = list(np.where(df['b'].isna()[0]))
To bash into a running container, type this:
docker exec -t -i container_name /bin/bash
or
docker exec -ti container_name /bin/bash
or
docker exec -ti container_name sh
You need a regular expression like "\\s+"
, which means: split whenever at least one whitespace is encountered. The full Java code is:
try {
String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
//
}
Its easy, just wrap it in a relative box like so:
<div class="relative">
<div class="absolute">LOGO</div>
</div>
The relative box has a margin: 0 Auto; and, important, a width...
Yes. IMHO, overriding GetWebRequest() is the best solution to WebClient's limited functionalty. Before I knew about this option, I wrote lots of really painful code at the HttpWebRequest layer because WebClient almost, but not quite, did what I needed. Derivation is much easier.
Another option is to use the regular WebClient class, but manually populate the Cookie header before making the request and then pull out the Set-Cookies header on the response. There are helper methods on the CookieContainer class which make creating and parsing these headers easier: CookieContainer.SetCookies()
and CookieContainer.GetCookieHeader()
, respectively.
I prefer the former approach since it's easier for the caller and requires less repetitive code than the second option. Also, the derivation approach works the same way for multiple extensibility scenarios (e.g. cookies, proxies, etc.).
Another solution would be to write a wrapper that store the array like this:
localStorage.setItem('names_length', names.length);
localStorage.setItem('names_0', names[0]);
localStorage.setItem('names_1', names[1]);
localStorage.setItem('names_' + n, names[n]);
Removes the overhead of converting to JSON, but would be annoying if you need to remove elements, as you would have to re-index the array :)
Add icon: https://developer.android.com/studio/write/vector-asset-studio.html
set icon: setIcon(R.drawable.ic_incon_name)
Correct expression is
"source " + (DT_STR,4,1252)DATEPART( "yyyy" , getdate() ) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mm" , getdate() ), 2) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "dd" , getdate() ), 2) +".CSV"

For windows, everybody said you should set environment variables for nodejs and npm modules, but do you know why? For some modules, they have command line tool, after installed the module, there'are [module].cmd file in C:\Program Files\nodejs, and it's used for launch in window command. So if you don't add the path containing the cmd file to environment variables %PATH% , you won't launch them successfully through command window.
The first and foremost condition that needs to be met is that both the parent and iframe should belong to the same origin. Once that is done the child can invoke the parent using window.opener method and the parent can do the same for the child as mentioned above
If every input asks the same question, you should use a for
loop and an array of inputs:
Scanner dd = new Scanner(System.in);
int[] vars = new int[3];
for(int i = 0; i < vars.length; i++) {
System.out.println("Enter next var: ");
vars[i] = dd.nextInt();
}
Or as Chip suggested, you can parse the input from one line:
Scanner in = new Scanner(System.in);
int[] vars = new int[3];
System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
vars[i] = in.nextInt();
You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.
li a {
width: 300px;
height: 100px;
display: table-cell;
vertical-align: middle;
margin: auto 0;
background: red;
}
Though asynchronous style may be the nature of node.js and generally you should not do this, there are some times you want to do this.
I'm writing a handy script to check an API and want not to mess it up with callbacks.
Javascript cannot execute synchronous requests, but C libraries can.
Breadth vs Depth; think in terms of a tree of references with your object as the root node.
Shallow:
The variables A and B refer to different areas of memory, when B is assigned to A the two variables refer to the same area of memory. Later modifications to the contents of either are instantly reflected in the contents of other, as they share contents.
Deep:
The variables A and B refer to different areas of memory, when B is assigned to A the values in the memory area which A points to are copied into the memory area to which B points. Later modifications to the contents of either remain unique to A or B; the contents are not shared.
This thing worked for me:
$scriptOutput = (cmd /s /c $FilePath $ArgumentList)
Do you mean like this?
import string
astr='a(b[c])d'
deleter=string.maketrans('()[]',' ')
print(astr.translate(deleter))
# a b c d
print(astr.translate(deleter).split())
# ['a', 'b', 'c', 'd']
print(list(reversed(astr.translate(deleter).split())))
# ['d', 'c', 'b', 'a']
print(' '.join(reversed(astr.translate(deleter).split())))
# d c b a
I too got this same error on my image handler that I wrote. I got it like 30 times a day on site with heavy traffic, managed to reproduce it also. You get this when a user cancels the request (closes the page or his internet connection is interrupted for example), in my case in the following row:
myContext.Response.OutputStream.Write(buffer, 0, bytesRead);
I can’t think of any way to prevent it but maybe you can properly handle this. Ex:
try
{
…
myContext.Response.OutputStream.Write(buffer, 0, bytesRead);
…
}catch (HttpException ex)
{
if (ex.Message.StartsWith("The remote host closed the connection."))
;//do nothing
else
//handle other errors
}
catch (Exception e)
{
//handle other errors
}
finally
{//close streams etc..
}
Do one thing, go to properties of database select files and increase initial size of database and set primary filegroup as autoincremented. Restart sql server.
You will be able to use database as earlier.
You didn't mention a file, so I assume you want to provide the XML string as standard input on the command line. In that case, do the following:
$ echo '<root><foo a="b">lorem</foo><bar value="ipsum" /></root>' | xmllint --format -
30x30 is points, which means 30px @1x, 60px @2x, not somewhere in-between. Also, it's not a great idea to embed the title of the tab into the image—you're going to have pretty poor accessibility and localization results like that.
(Posting in case someone might have a use of it).
I was looking for a solution for a problem a bit more sophisticated than OP - replacing EVERY occurrence of something with the number by same thing with incremented number
E.g. Replacing something like this:
<row id="1" />
<row id="2" />
<row id="1" />
<row id="3" />
<row id="1" />
By this:
<row id="2" />
<row id="3" />
<row id="2" />
<row id="4" />
<row id="2" />
Couldnt find the solution online so I wrote my own script in groovy (a bit ugly but does the job):
/**
* <p> Finds words that matches template and increases them by 1.
* '_' in word template represents number.
*
* <p> E.g. if template equals 'Row="_"', then:
* ALL Row=0 will be replaced by Row="1"
* All Row=1 will be replaced by Row="2"
* <p> Warning - your find template might not work properly if _ is the last character of it
* etc.
* <p> Requirments:
* - Original text does not contain tepmlate string
* - Only numbers in non-disrupted sequence are incremented and replaced
* (i.e. from example below, if Row=4 exists in original text, but Row=3 not, than Row=4 will NOT be
* replaced by Row=5)
*/
def replace_inc(String text, int startingIndex, String findTemplate) {
assert findTemplate.contains('_') : 'search template needs to contain "_" placeholder'
assert !(findTemplate.replaceFirst('_','').contains('_')) : 'only one "_" placeholder is allowed'
assert !text.contains('_____') : 'input text should not contain "______" (5 underscores)'
while (true) {
findString = findTemplate.replace("_",(startingIndex).toString())
if (!text.contains(findString)) break;
replaceString = findTemplate.replace("_", "_____"+(++startingIndex).toString())
text = text.replaceAll(findString, replaceString)
}
return text.replaceAll("_____","") // get rid of '_____' character
}
// input
findTemplate = 'Row="_"'
path = /C:\TEMP\working_copy.txt/
startingIndex = 0
// do stuff
f = new File(path)
outText = replace_inc(f.text,startingIndex,findTemplate)
println "Results \n: " + outText
f.withWriter { out -> out.println outText }
println "Results written to $f"
Use:
File.open("out.txt", [your-option-string]) {|f| f.write("write your stuff here") }
where your options are:
r
- Read only. The file must exist. w
- Create an empty file for writing. a
- Append to a file.The file is created if it does not exist. r+
- Open a file for update both reading and writing. The file must exist. w+
- Create an empty file for both reading and writing. a+
- Open a file for reading and appending. The file is created if it does not exist. In your case, 'w'
is preferable.
OR you could have:
out_file = File.new("out.txt", "w")
#...
out_file.puts("write your stuff here")
#...
out_file.close

Sleep is used in cases where independent program(s) that you have no control over may sometimes use a commonly used resource (say, a file), that your program needs to access when it runs, and when the resource is in use by these other programs your program is blocked from using it. In this case, where you access the resource in your code, you put your access of the resource in a try-catch (to catch the exception when you can't access the resource), and you put this in a while loop. If the resource is free, the sleep never gets called. But if the resource is blocked, then you sleep for an appropriate amount of time, and attempt to access the resource again (this why you're looping). However, bear in mind that you must put some kind of limiter on the loop, so it's not a potentially infinite loop. You can set your limiting condition to be N number of attempts (this is what I usually use), or check the system clock, add a fixed amount of time to get a time limit, and quit attempting access if you hit the time limit.
Yes, you can!))
Disclaimer: This is not a solution, it is more of a hack to test out something. User-defined functions cannot be used to perform actions that modify the database state.
I found one way to make INSERT
, UPDATE
or DELETE
in function using xp_cmdshell
.
So you need just to replace the code inside @sql variable.
CREATE FUNCTION [dbo].[_tmp_func](@orderID NVARCHAR(50))
RETURNS INT
AS
BEGIN
DECLARE @sql varchar(4000), @cmd varchar(4000)
SELECT @sql = 'INSERT INTO _ord (ord_Code) VALUES (''' + @orderID + ''') '
SELECT @cmd = 'sqlcmd -S ' + @@servername +
' -d ' + db_name() + ' -Q "' + @sql + '"'
EXEC master..xp_cmdshell @cmd, 'no_output'
RETURN 1
END
If you have two []byte
, compare them using bytes.Equal. The Golang documentation says:
Equal returns a boolean reporting whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.
Usage:
package main
import (
"fmt"
"bytes"
)
func main() {
a := []byte {1,2,3}
b := []byte {1,2,3}
c := []byte {1,2,2}
fmt.Println(bytes.Equal(a, b))
fmt.Println(bytes.Equal(a, c))
}
This will print
true
false
Usually, if you have big python objects it's quite hard to format them. I personally prefer using some tools for that.
Here is python-beautifier - www.cleancss.com/python-beautify that instantly turns your data into customizable style.
What I tend to do, and I believe this is what Google intended for developers to do too, is to still get the extras from an Intent
in an Activity
and then pass any extra data to fragments by instantiating them with arguments.
There's actually an example on the Android dev blog that illustrates this concept, and you'll see this in several of the API demos too. Although this specific example is given for API 3.0+ fragments, the same flow applies when using FragmentActivity
and Fragment
from the support library.
You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment:
public static class DetailsActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// (omitted some other stuff)
if (savedInstanceState == null) {
// During initial setup, plug in the details fragment.
DetailsFragment details = new DetailsFragment();
details.setArguments(getIntent().getExtras());
getSupportFragmentManager().beginTransaction().add(
android.R.id.content, details).commit();
}
}
}
In stead of directly invoking the constructor, it's probably easier to use a static method that plugs the arguments into the fragment for you. Such a method is often called newInstance
in the examples given by Google. There actually is a newInstance
method in DetailsFragment
, so I'm unsure why it isn't used in the snippet above...
Anyways, all extras provided as argument upon creating the fragment, will be available by calling getArguments()
. Since this returns a Bundle
, its usage is similar to that of the extras in an Activity
.
public static class DetailsFragment extends Fragment {
/**
* Create a new instance of DetailsFragment, initialized to
* show the text at 'index'.
*/
public static DetailsFragment newInstance(int index) {
DetailsFragment f = new DetailsFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
f.setArguments(args);
return f;
}
public int getShownIndex() {
return getArguments().getInt("index", 0);
}
// (other stuff omitted)
}
In order to rename a table in a different schema, try:
ALTER TABLE owner.mytable RENAME TO othertable;
The rename command (as in "rename mytable to othertable
") only supports renaming a table in the same schema.
uniq -u < file
will do the job.
to select records for the last 7 days
WHERE Created_Date >= DATEADD(day, -7, GETDATE())
to select records for the current week
SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
AND CreatedDate < DATEADD(day, 8 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
if you want to select records for last week instead of the last 7 days
SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, -(DATEPART(dw, GETDATE()) + 6), CONVERT(DATE, GETDATE()))
AND CreatedDate < DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))
Guaranteed to be (statistically) unique:
string fileName = System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() + ".csv";
(To quote from the wiki article on the probabilty of a collision:
...one's annual risk of being hit by a meteorite is estimated to be one chance in 17 billion [19], that means the probability is about 0.00000000006 (6 × 10-11), equivalent to the odds of creating a few tens of trillions of UUIDs in a year and having one duplicate. In other words, only after generating 1 billion UUIDs every second for the next 100 years, the probability of creating just one duplicate would be about 50%. The probability of one duplicate would be about 50% if every person on earth owns 600 million UUIDs
EDIT: Please also see JaredPar's comments.
The results are ordered by the first column, then the second, and so on for as many columns as the ORDER BY clause includes. If you want any results sorted in descending order, your ORDER BY clause must use the DESC keyword directly after the name or the number of the relevant column.
Check out this Example
SELECT first_name, last_name, hire_date, salary
FROM employee
ORDER BY hire_date DESC,last_name ASC;
It will order in succession. Order the Hire_Date first, then LAST_NAME it by Hire_Date .
Varchar is for small data like email addresses, while Text is for much bigger data like news articles, Blob for binary data such as images.
The performance of Varchar is more powerful because it runs completely from memory, but this will not be the case if data is too big like varchar(4000)
for example.
Text, on the other hand, does not stick to memory and is affected by disk performance, but you can avoid that by separating text data in a separate table and apply a left join query to retrieve text data.
Blob is much slower so use it only if you don't have much data like 10000 images which will cost 10000 records.
Follow these tips for maximum speed and performance:
Use varchar for name, titles, emails
Use Text for large data
Separate text in different tables
Use Left Join queries on an ID such as a phone number
If you are going to use Blob apply the same tips as in Text
This will make queries cost milliseconds on tables with data >10 M and size up to 10GB guaranteed.
I had a similar problem when attempting to update one DLL file of my web-site.
This error was occurring, when I simply copied this DLL file into bin folder over FTP.
I resolved this problem by:
Accurate and fast will give output in seconds:
let startDate = new Date()
let endDate = new Date("yyyy-MM-dd'T'HH:mm:ssZ");
let seconds = Math.round((endDate.getTime() - startDate.getTime()) / 1000);
in your main file add this:
import sys
import os
sys.path.append(os.path.abspath(os.path.join(__file__,mainScriptDepth)))
mainScriptDepth = the depth of the main file from the root of the project.

Many questions get answers if we use .Net Reflector

true
and sspi
are the same:
internal class DbConnectionOptions
...
internal bool ConvertValueToIntegratedSecurityInternal(string stringValue)
{
if ((CompareInsensitiveInvariant(stringValue, "sspi") || CompareInsensitiveInvariant(stringValue, "true")) || CompareInsensitiveInvariant(stringValue, "yes"))
{
return true;
}
}
...
EDIT 20.02.2018 Now in .Net Core we can see its open source on github! Search for ConvertValueToIntegratedSecurityInternal method:
Please find the actual css from Bootstrap
.container-fluid {
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
}
.row {
margin-right: -15px;
margin-left: -15px;
}
When you add a .container-fluid
class, it adds a horizontal padding of 15px, and the same will be removed when you add a .row
class as a child element by the negative margin set on row.
You still need to explicitly inline your function when doing template specialization (if specialization is in .h file)
You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:
//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));
//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();

One note for people who might not have the set password for sysdba or sys and regularly use a third party client. Here's some info about logging into command line sqlplus without a password that helped me. I am using fedora 21 by the way.
locate sqlplus
In my case, sqlplus is located here:
/u01/app/oracle/product/11.2.0/xe/config/scripts/sqlplus.sh
Now run
cd /u01/app/oracle/product/11.2.0/xe/config/scripts
./sqlplus.sh / as sysdba
Now you need to connect to database with your old credentials. You can find Oracle provided template in your output:
Use "connect username/password@XE" to connect to the database.
In my case I have user "oracle" with password "oracle" so my input looks like
connect oracle/oracle@XE
Done. Now type your new password twice. Then if you don't want your password to expire anymore you could run
ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;
Time::Piece (in core since Perl 5.10) also has a strftime function and by default overloads localtime and gmtime to return Time::Piece objects:
use Time::Piece;
print localtime->strftime('%Y-%m-%d');
or without the overridden localtime:
use Time::Piece ();
print Time::Piece::localtime->strftime('%F %T');
A way that might be more convenient: where you want a breakpoint, write a no-op if statement and set a breakpoint in its contents.
if(tablist[i].equalsIgnoreCase("LEADDELEGATES")) {
--> int noop = 0; //don't do anything
}
(the breakpoint is represented by the arrow)
This way, the breakpoint only triggers if your condition is true. This could potentially be easier without that many pop-ups.
You need to define MyMessageBox before User -- because User include object of MyMessageBox by value (and so compiler should know its size).
Also you'll need to forward declare User befor MyMessageBox -- because MyMessageBox include member of User* type.

The numpy .tolist method produces nested lists if the numpy array shape is 2D.
if flat lists are desired, the method below works.
import numpy as np
from itertools import chain
a = [1,2,3,4,5,6,7,8,9]
print type(a), len(a), a
npa = np.asarray(a)
print type(npa), npa.shape, "\n", npa
npa = npa.reshape((3, 3))
print type(npa), npa.shape, "\n", npa
a = list(chain.from_iterable(npa))
print type(a), len(a), a`
*
means receive variable arguments as tuple
**
means receive variable arguments as dictionary
Used like the following:
1) single *
def foo(*args):
for arg in args:
print(arg)
foo("two", 3)
Output:
two
3
2) Now **
def bar(**kwargs):
for key in kwargs:
print(key, kwargs[key])
bar(dic1="two", dic2=3)
Output:
dic1 two
dic2 3
What is the main difference. Like memory or performance implications
The difference between static and dynamic resources comes when the underlying object changes. If your Brush defined in the Resources collection were accessed in code and set to a different object instance, Rectangle will not detect this change.
Static Resources retrieved once by referencing element and used for the lifetime of the resources. Whereas, DynamicResources retrieve every time they are used.
The downside of Dynamic resources is that they tend to decrease application performance.
Are there rules in WPF like "brushes are always static" and "templates are always dynamic" etc.?
The best practice is to use Static Resources unless there is a specific reason like you want to change resource in the code behind dynamically. Another example of instance in which you would want t to use dynamic resoruces include when you use the SystemBrushes, SystenFonts and System Parameters.
You can use mongo --eval 'printjson(db.getCollectionNames())'
to get the list of collections
and then do a mongoexport on all of them.
Here is an example in ruby
out = `mongo #{DB_HOST}/#{DB_NAME} --eval "printjson(db.getCollectionNames())"`
collections = out.scan(/\".+\"/).map { |s| s.gsub('"', '') }
collections.each do |collection|
system "mongoexport --db #{DB_NAME} --collection #{collection} --host '#{DB_HOST}' --out #{collection}_dump"
end
Nowadays, Alpine images will boot directly into /bin/sh
by default, without having to specify a shell to execute:
$ sudo docker run -it --rm alpine
/ # echo $0
/bin/sh
This is since the alpine
image Dockerfiles now contain a CMD
command, that specifies the shell to execute when the container starts: CMD ["/bin/sh"]
.
In older Alpine image versions (pre-2017), the CMD command was not used, since Docker used to create an additional layer for CMD which caused the image size to increase. This is something that the Alpine image developers wanted to avoid. In recent Docker versions (1.10+), CMD no longer occupies a layer, and so it was added to alpine
images. Therefore, as long as CMD is not overridden, recent Alpine images will boot into /bin/sh
.
For reference, see the following commit to the official Alpine Dockerfiles by Glider Labs:
https://github.com/gliderlabs/docker-alpine/commit/ddc19dd95ceb3584ced58be0b8d7e9169d04c7a3#diff-db3dfdee92c17cf53a96578d4900cb5b
If you need to display all the records after 2014-09-01, add this to your query:
SELECT * FROM Events
WHERE Format(Events.DATE_TIME,'yyyy-MM-dd hh:mm:ss') >= Format("2014-09-01 00:00:00","yyyy-MM-dd hh:mm:ss")
From a cmd:
&
is escaped like this: ^&
(based on @Wael Dalloul's answer)%
does not need to be escapedAn example:
start http://www.google.com/search?client=opera^&rls=en^&q=escape+ampersand%20and%20percentage+in+cmd^&sourceid=opera^&ie=utf-8^&oe=utf-8
From a batch file
&
is escaped like this: ^&
(based on @Wael Dalloul's answer)%
is escaped like this: %%
(based on the OPs update)An example:
start http://www.google.com/search?client=opera^&rls=en^&q=escape+ampersand%%20and%%20percentage+in+batch+file^&sourceid=opera^&ie=utf-8^&oe=utf-8
The answer probably depends on what format your date is in, but here is an example using the Date
class:
dt <- as.Date("2010/02/10")
new.dt <- dt - as.difftime(2, unit="days")
You can even play with different units like weeks.
A way that will fail if your input string isn't valid pairs of hex characters...:

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.
I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.
While some of the other approaches work, this is pretty close to what you were doing and only uses base r. If you know the aggregate command this may be more intuitive.
with( df , aggregate( dt , by=list(group) , FUN=summary) )
Add this option
--driver-java-options -Xss512m
to your spark-submit command will fix this issue.
There are (more than) three popular ways to use MySQL from PHP. This outlines some features/differences PHP: Choosing an API:
I would recommend using PDO with prepared statements. It is a well-designed API and will let you more easily move to another database (including any that supports ODBC) if necessary.
I have referenced this question several times, and gone on to actually find the answer I was looking for here: pyodbc wiki
To avoid gcc error on Ubuntu Linux, I did:
sudo aptitude install g++
I also installed the following 2 packages from Synaptic:
python-dev

Laravel min

validation do not work properly with a numeric
rule validation. Instead of numeric, min and max
, Laravel provided a rule digits_between
.
$this->validate($request,[

Just add a question mark ?
to the optional field.

For Swift 3:
extension SystemSoundID {
static func playFileNamed(_ fileName: String, withExtenstion fileExtension: String) {
var sound: SystemSoundID = 0
if let soundURL = Bundle.main.url(forResource: fileName, withExtension: fileExtension) {
AudioServicesCreateSystemSoundID(soundURL as CFURL, &sound)
AudioServicesPlaySystemSound(sound)
}
}
}
String
vs string
Argument of type 'String' is not assignable to parameter of type 'string'.
'string' is a primitive, but 'String' is a wrapper object.
Prefer using 'string' when possible.
String Object
// error
class SVGStorageUtils {
store: object;
constructor(store: object) {
this.store = store;
}
setData(key: String = ``, data: object) {
sessionStorage.setItem(key, JSON.stringify(data));
}
getData(key: String = ``) {
const obj = JSON.parse(sessionStorage.getItem(key));
}
}
string primitive
// ok
class SVGStorageUtils {
store: object;
constructor(store: object) {
this.store = store;
}
setData(key: string = ``, data: object) {
sessionStorage.setItem(key, JSON.stringify(data));
}
getData(key: string = ``) {
const obj = JSON.parse(sessionStorage.getItem(key));
}
}
In C++, Boost Variant implement a safe version of the union, designed to prevent undefined behavior as much as possible.
Its performances are identical to the enum + union

Use this link http://ip-api.com/json ,this will provide all the information as json. From this json you can get the country easily. This site works using your current IP,it automatically detects the IP and sendback details.
Docs http://ip-api.com/docs/api:json Hope it helps.
Example json

"country": "United States",
"countryCode": "US",
"region": "CA",

note : As this is a 3rd party solution, only use if others didn't work.
One way:
def change(f):
if f is None:
return unicode(f.strip())
else:
return ''
row = [change(x) for x in row]
Although then you have:
row = map(change, row)
Or you can use a lambda inline.
Solution is just simple.
If you are trying to access server using your local IP address and you are getting error saying like Forbidden You don't have permission to access / on this server
Just open your httpd.conf file from (in my case C:/wamp/bin/apache/apache2.2.21/conf/httpd.conf
)
Search for
<Directory "D:/wamp/www/">
....
.....
</Directory>
Replace Allow from 127.0.0.1
to
Allow from all
Save changes and restart your server.
Now you can access your server using your IP address
If you're building a class library, then perhaps the users of your library would like to use your library asynchronously. I think that's the biggest reason right there.
You also don't know how your library is going to be used. Perhaps the users will be processing lots and lots of requests, and doing so asynchronously will help it perform faster and more efficient.
If you can do so simply, try not to put the burden on the users of your library trying to make the flow asynchronous when you can take care of it for them.
The only reason I wouldn't use the async version is if I were trying to support an older version of .NET that does not already have built in async support.
[2017-07-25] since this continues to be the accepted answer, despite being a very hacky solution, I'm incorporating Gabi's code into it, leaving my own to serve as a bad example.
// my hacky approach:
function get_content() {
var html = document.getElementById("txt").innerHTML;
document.getElementById("txt").innerHTML = html.replace(/<[^>]*>/g, "");
}
// Gabi's elegant approach, but eliminating one unnecessary line of code:
function gabi_content() {
var element = document.getElementById('txt');
element.innerHTML = element.innerText || element.textContent;
}
// and exploiting the fact that IDs pollute the window namespace:
function txt_content() {
txt.innerHTML = txt.innerText || txt.textContent;
}

The simplest way is to create a VBA macro that wraps that function, like so:
Function UserNameWindows() As String
UserName = Environ("USERNAME")
End Function
Then call it from the cell:
=UserNameWindows()
See this article for more details, and other ways.
The above options works for Google big query file also. I exported a table data to goodle cloud storage and downloaded from there. While loading the same to sql server was facing this issue and could successfully load the file after specifying the row delimiter as
ROWTERMINATOR = '0x0a'
Pay attention to header record as well and specify
FIRSTROW = 2
My final block for data file export from google bigquery looks like this.
BULK INSERT TABLENAME
FROM 'C:\ETL\Data\BigQuery\In\FILENAME.csv'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = ',', --CSV field delimiter
ROWTERMINATOR = '0x0a',--Files are generated with this row terminator in Google Bigquery
TABLOCK
)
Here's a simple example with no jQuery. Use URL.createObjectURL
, which
creates a DOMString containing a URL representing the object given in the parameter
Then, you can simply set the src
of the image to that url:
window.addEventListener('load', function() {
document.querySelector('input[type="file"]').addEventListener('change', function() {
if (this.files && this.files[0]) {
var img = document.querySelector('img');
img.onload = () => {
URL.revokeObjectURL(img.src); // no longer needed, free memory
}
img.src = URL.createObjectURL(this.files[0]); // set src to blob url
}
});
});

<input type='file' />
<br><img id="myImg" src="#">

JKALAVIS solution is good, however I would add an improvement to use shlex instead of SHELL=TRUE. below im grepping out Query times
#!/bin/python
import subprocess
import shlex
cmd = "dig @8.8.4.4 +notcp www.google.com|grep 'Query'"
ps = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
output = ps.communicate()[0]
print(output)
/\{([^}]+)\}/
/ - delimiter
\{ - opening literal brace escaped because it is a special character used for quantifiers eg {2,3}
( - start capturing
[^}] - character class consisting of
^ - not
} - a closing brace (no escaping necessary because special characters in a character class are different)
+ - one or more of the character class
) - end capturing
\} - the closing literal brace
/ - delimiter
If possible use Visual Studio. The Microsoft SQL Server Data Tools (SSDT) bring a built in functionality for this since the March 2014 release:
Note: Be careful, the "View Data" window is just like SSMS "Edit Top 200 Rows"- you can edit data right away
(Tested with Visual Studio 2015 with Microsoft SQL Server Data Tools (SSDT) Version 14.0.60812.0 and Microsoft SQL Server 2012)
Insert command tree in bash.
Also, there is a DOS comnand "tree". You can displays directory paths and files in each subdirectory with command:
tree /F
If you don't have avahi installed then it's probably cups.
absolute positioning is evil... this solution doesn't take into account window size. If you resize the browser window, your div will be out of place!
This worked for me on my Oracle database:
SELECT 'GRANT SELECT, insert, update, delete ON mySchema.' || TABLE_NAME || ' to myUser;'
FROM user_tables
where table_name like 'myTblPrefix%'
Then, copy the results, paste them into your editor, then run them like a script.
You could also write a script and use "Execute Immediate" to run the generated SQL if you don't want the extra copy/paste steps.
For varchars, you may need to do something like this:
select convert(varchar(25), NULL) as abc_column into xyz_table
If you try
select '' as abc_column into xyz_table
you may get errors related to truncation, or an issue with null values, once you populate.
Because it was not posted yet and is a simple css fix:
#canvas {
position:fixed;
left:0;
top:0;
width:100%;
height:100%;
}
Works great if you want to apply a fullscreen canvas background (for example with Granim.js).
Try below code:
$(document).ready(function(){
$('#about').css({'background-color':'black'});
});
You need to pass an array of element to jsx
. The problem is that forEach
does not return anything (i.e it returns undefined
). So it's better to use map
because map
returns an array:
class QuestionSet extends Component {
render(){
<div className="container">
<h1>{this.props.question.text}</h1>
{this.props.question.answers.map((answer, i) => {
console.log("Entered");
// Return the element. Also pass key
return (<Answer key={answer} answer={answer} />)
})}
}
export default QuestionSet;
numpy already allows the creation of arrays of all ones or all zeros very easily:
e.g. numpy.ones((2, 2))
or numpy.zeros((2, 2))
Since True
and False
are represented in Python as 1
and 0
, respectively, we have only to specify this array should be boolean using the optional dtype
parameter and we are done.
numpy.ones((2, 2), dtype=bool)
returns:
array([[ True, True],
[ True, True]], dtype=bool)
UPDATE: 30 October 2013
Since numpy version 1.8, we can use full
to achieve the same result with syntax that more clearly shows our intent (as fmonegaglia points out):
numpy.full((2, 2), True, dtype=bool)
UPDATE: 16 January 2017
Since at least numpy version 1.12, full
automatically casts results to the dtype
of the second parameter, so we can just write:
numpy.full((2, 2), True)
Try to encode backslash between domain and user

I just had the same problem. I declared a variable putting my text with the @.
@{

Try this code
NSNumber *number = @([dictionary[@"keyValue"] intValue]]);
This may help you. Thanks
This API has been available for a long time and enables to get access to market data (including live) if you are running a Bloomberg Terminal or have access to a Bloomberg Server, which is chargeable.
The only difference is that the API (not its code) has been open sourced, so it can now be used as a dependency in an open source project for example, without any copyrights issues, which was not the case before.
You can specify '-m32' or '-m64' to select the compilation mode.
When dealing with autoconf (configure) scripts, I usually set CC="gcc -m64" (or CC="gcc -m32") in the environment so that everything is compiled with the correct bittiness. At least, usually...people find endless ways to make that not quite work, but my batting average is very high (way over 95%) with it.
You can use the Android app Barcode Scanner Terminal (DISCLAIMER! I'm the developer). It can scan the barcode and send it to the PC and in your case enter it on the web form. More details here.

<h2>Solution 2: Using <code>display: inline-block</code> and <code>text-align</code> (IE8)</h2>_x000D_
_x000D_
<p>This method utilizes that <code>inline-block</code> elements are treated as text and as such they are affected by the <code>text-align</code> property.

<h2>Solution 4: Using <code>translate()</code> and <code>position</code> (IE9)</h2>_x000D_
_x000D_
<p>Don’t use as a general approach for horizontal centering elements. The downside here is that the centered element will be removed from the document flow. Notice the container shrinking to zero height with only the padding keeping it visible. This is what <i>removing an element from the document flow</i> means.</p>_x000D_
_x000D_
<p>There are however applications for this technique. For example, it works for <b>vertically</b> centering by using <code>top</code> or <code>bottom</code> together with <code>translateY()</code>.</p>_x000D_

.container {
display: flex;
justify-content: center;
}
Notes:
max-width
& margin
You can horizontally center a block-level element by assigning a fixed width and setting margin-right
and margin-left
to auto
.
.container ul {
/* for IE below version 7 use `width` instead of `max-width` */
max-width: 800px;
margin-right: auto;
margin-left: auto;
}
Notes:
transform: translatex(-50%)
& left: 50%
This is similar to the quirky centering method which uses absolute positioning and negative margins.
.container {
position: relative;
}
.container ul {
position: absolute;
left: 50%;
transform: translatex(-50%);
}
Notes:
top
instead of left
and translateY()
instead of translateX()
. The two can even be combined. transform2d
display: table
& margin
Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table
property value for display
.
.container ul {
display: table;
margin-right: auto;
margin-left: auto;
}
display: inline-block
& text-align
Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.
.container {
text-align: center;
}
.container ul {
display: inline-block;
/* One most likely needs to realign flow content */
text-align: initial;
}
Notes:
I'm not fully sure that this is what you're looking for, but if your question is how to read an integer using <stdio.h>
, then the proper syntax is
int myInt;
scanf("%d", &myInt);
You'll need to do a lot of error-handling to ensure that this works correctly, of course, but this should be a good start. In particular, you'll need to handle the cases where
stdin
file is closed or broken, so you get nothing at all.To check for this, you can capture the return code from scanf
like this:
int result = scanf("%d", &myInt);
If stdin
encounters an error while reading, result
will be EOF
, and you can check for errors like this:
int myInt;
int result = scanf("%d", &myInt);
if (result == EOF) {
/* ... you're not going to get any input ... */
}
If, on the other hand, the user enters something invalid, like a garbage text string, then you need to read characters out of stdin
until you consume all the offending input. You can do this as follows, using the fact that scanf
returns 0 if nothing was read:
int myInt;
int result = scanf("%d", &myInt);
if (result == EOF) {
/* ... you're not going to get any input ... */
}
if (result == 0) {
while (fgetc(stdin) != '\n') // Read until a newline is found
;
}
Hope this helps!
EDIT: In response to the more detailed question, here's a more appropriate answer. :-)
The problem with this code is that when you write
printf("got the number: %d", scanf("%d", &x));
This is printing the return code from scanf
, which is EOF
on a stream error, 0
if nothing was read, and 1
otherwise. This means that, in particular, if you enter an integer, this will always print 1
because you're printing the status code from scanf
, not the number you read.
To fix this, change this to
int x;
scanf("%d", &x);
/* ... error checking as above ... */
printf("got the number: %d", x);
Hope this helps!
Use JsonResponse
from django.http import JsonResponse
In order to avoid such error you could use CASE
+ ISNUMERIC
to handle scenarios when you cannot convert to int.
Change
CONVERT(INT, CONVERT(VARCHAR(12), a.value))
To
CONVERT(INT,
CASE
WHEN IsNumeric(CONVERT(VARCHAR(12), a.value)) = 1 THEN CONVERT(VARCHAR(12),a.value)
ELSE 0 END)
Basically this is saying if you cannot convert me to int assign value of 0 (in my example)
Alternatively you can look at this article about creating a custom function that will check if a.value
is number: http://www.tek-tips.com/faqs.cfm?fid=6423
I had this problem also. I set the correct settings and have enabled less secure apps but it still did not work. Finally, I enabled this https://accounts.google.com/UnlockCaptcha, and it worked for me. I hope this helps someone.

I think this is related to the newer version of spring boot plus using spring data JPA just replace @Bean annotation above public LocalContainerEntityManagerFactoryBean entityManagerFactory() to @Bean(name="entityManagerFactory")

I don't know which version of Python you are using but I tried this in Python 3 and made a few changes and it looks like it works. The raw_input function seems to be the issue here. I changed all the raw_input functions to "input()" and I also made minor changes to the printing to be compatible with Python 3. AJ Uppal is correct when he says that you shouldn't name a variable and a function with the same name. See here for reference:
TypeError: 'int' object is not callable
My code for Python 3 is as follows:

I noticed a small bug in your code as well. This function should ideally convert pounds to kilograms but it looks like when it prints, it is printing "Centimeters" instead of kilograms.
def convertPK():
input_P = float(input(("Pounds: ")))
P_conv = input_P * 0.45
# Printing error in the line below
print("Centimeters: {P_conv}\n")

Unfortunately there is no such a thing as Lock/Unlock. What you have to do is:
Enter the below query:

There is a library for this BarCode PHP. You just need to include a few files:
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
You can generate many types of barcodes, namely 1D or 2D. Add the required library:
require_once('class/BCGcode39.barcode.php');
Generate the colours:
// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);
After you have added all the codes, you will get this way:
Example
Since several have asked for an example here is what I was able to do to get it done
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
require_once('class/BCGcode128.barcode.php');
header('Content-Type: image/png');
$color_white = new BCGColor(255, 255, 255);
$code = new BCGcode128();
$code->parse('HELLO');
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
If you want to actually create the image file so you can save it then change
$drawing = new BCGDrawing('', $color_white);
to
$drawing = new BCGDrawing('image.png', $color_white);
You can use Query.values, Query.values
session.query(SomeModel).values('id', 'user')
The accepted answer is one way of fixing the issue, because it will just apply some strategy for the problematic dependency (com.google.code.findbugs:jsr305) and it will resolve the problem around the project, using some version of this dependency. Basically it will align the versions of this library inside the whole project.
There is an answer from @Santhosh (and couple of other people) who suggests to exclude the same dependency for espresso, which should work by the same way, but if the project has some other dependencies who depend on the same library (com.google.code.findbugs:jsr305), again we will have the same issue. So in order to use this approach you will need to exclude the same group from all project dependencies, who depend on com.google.code.findbugs:jsr305. I personally found that Espresso Contrib and Espresso Intents also use com.google.code.findbugs:jsr305.
I hope this thoughts will help somebody to realise what exactly is happening here and how things work (not just copy paste some code) :).
The primary key is already protecting you from inserting duplicate values, as you're experiencing when you get that error. Adding another unique constraint isn't necessary to do that.
The "duplicate key" error is telling you that the work was not done because it would produce a duplicate key, not that it discovered a duplicate key already commited to the table.
Which method is used to check if SESSION exists or not? Answer:
isset($_SESSION['variable_name'])

You can change the access modifier for the generated field in Form1.Designer.cs
from private
to public
. Change this
private System.Windows.Forms.TextBox textBox1;
by this
public System.Windows.Forms.TextBox textBox1;
You can now handle it using a reference of the form Form1.textBox1
.
Visual Studio will not overwrite this if you make any changes to the control properties, unless you delete it and recreate it.
You can also chane it from the UI if you are not confortable with editing code directly. Look for the Modifiers property:
I've had the same problem on Eclipse Juno.
No "Welcome page" appeared, I could not create a project, compilation didn't work and "Graphical layout" didn't work.

Reestart Eclipse.
Of course you have to be configured this: Window - Preferences - Android - SDK Location and setup SDK path.

..., the use of the numpy.matrix class is discouraged, since it adds nothing that cannot be accomplished with 2D numpy.ndarray objects, and may lead to a confusion of which class is being used. For example,
>>> import numpy as np
>>> from scipy import linalg
>>> A = np.array([[1,2],[3,4]])
>>> A
array([[1, 2],
[3, 4]])
>>> linalg.inv(A)
array([[-2. , 1. ],
[ 1.5, -0.5]])
>>> b = np.array([[5,6]]) #2D array
>>> b
array([[5, 6]])
>>> b.T
array([[5],
[6]])
>>> A*b #not matrix multiplication!
array([[ 5, 12],
[15, 24]])
>>> A.dot(b.T) #matrix multiplication
array([[17],
[39]])
>>> b = np.array([5,6]) #1D array
>>> b
array([5, 6])
>>> b.T #not matrix transpose!
array([5, 6])
>>> A.dot(b) #does not matter for multiplication
array([17, 39])
scipy.linalg operations can be applied equally to numpy.matrix or to 2D numpy.ndarray objects.

Your string is invalid, but assuming it was valid, you'd have to do:
var finalData = str.replace(/\\/g, "");
When you want to replace all the occurences with .replace
, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.
Cheers
There's no direct function for this, but you can do it with a replace:
declare @myvar varchar(20)
set @myvar = 'Hello World'
select len(@myvar) - len(replace(@myvar,'o',''))
Basically this tells you how many chars were removed, and therefore how many instances of it there were.
Extra:
The above can be extended to count the occurences of a multi-char string by dividing by the length of the string being searched for. For example:
declare @myvar varchar(max), @tocount varchar(20)
set @myvar = 'Hello World, Hello World'
set @tocount = 'lo'
select (len(@myvar) - len(replace(@myvar,@tocount,''))) / LEN(@tocount)

Here is a jQuery plugin that will handle everything for you, Transify (Transify - a jQuery plugin to easily apply transparency / opacity to an element’s background).
I was running into this problem every now and then, so I decided to write something that would make life a lot easier. The script is less than 2 KB and it only requires one line of code to get it to work, and it will also handle animating the opacity of the background if you like.

There are other examples in the documentation. I'm guessing this feature was added after the previous answer.
the publicPath is just used for dev purpose, I was confused at first time I saw this config property, but it makes sense now that I've used webpack for a while
suppose you put all your js source file under src
folder, and you config your webpack to build the source file to dist
folder with output.path
.
But you want to serve your static assets under a more meaningful location like webroot/public/assets
, this time you can use out.publicPath='/webroot/public/assets'
, so that in your html, you can reference your js with <script src="/webroot/public/assets/bundle.js"></script>
.
when you request webroot/public/assets/bundle.js
the webpack-dev-server
will find the js under the dist folder
Update:
thanks for Charlie Martin to correct my answer
original: the publicPath is just used for dev purpose, this is not just for dev purpose
No, this option is useful in the dev server, but its intention is for asynchronously loading script bundles in production. Say you have a very large single page application (for example Facebook). Facebook wouldn't want to serve all of its javascript every time you load the homepage, so it serves only whats needed on the homepage. Then, when you go to your profile, it loads some more javascript for that page with ajax. This option tells it where on your server to load that bundle from

You can find a PCA function in the matplotlib module:
import numpy as np
from matplotlib.mlab import PCA
data = np.array(np.random.randint(10,size=(10,3)))
results = PCA(data)
results will store the various parameters of the PCA. It is from the mlab part of matplotlib, which is the compatibility layer with the MATLAB syntax
EDIT: on the blog nextgenetics I found a wonderful demonstration of how to perform and display a PCA with the matplotlib mlab module, have fun and check that blog!
I've recently been struggling with a related issue, discussed at length here: Order of legend entries in ggplot2 barplots with coord_flip() .
As it happens, the reason I had a hard time explaining my issue clearly, involved the relation between (the order of) factors and coord_flip(), as seems to be the case here.
I get the desired result by adding + xlim(rev(levels(x$variable)))
to the ggplot statement:
ggplot(x, aes(x=variable,y=value)) + geom_bar() +
scale_y_continuous("",formatter="percent") + coord_flip()
+ xlim(rev(levels(x$variable)))
This reverses the order of factors as found in the original data frame in the x-axis, which will become the y-axis with coord_flip(). Notice that in this particular example, the variable also happen to be in alphabetical order, but specifying an arbitrary order of levels within xlim()
should work in general.
Ok Got it, I downloaded a custom concatenation function and then just referenced its cells
Code
Function concat(useThis As Range, Optional delim As String) As String
' this function will concatenate a range of cells and return one string
' useful when you have a rather large range of cells that you need to add up
Dim retVal, dlm As String
retVal = ""
If delim = Null Then
dlm = ""
Else
dlm = delim
End If
For Each cell In useThis
if cstr(cell.value)<>"" and cstr(cell.value)<>" " then
retVal = retVal & cstr(cell.Value) & dlm
end if
Next
If dlm <> "" Then
retVal = Left(retVal, Len(retVal) - Len(dlm))
End If
concat = retVal
End Function
In my case was Promise with no reject neither resolve, because my Promise function threw an exception. This mistake cause UnhandledPromiseRejectionWarning message.
For Node/Express developers you can use middleware and set this via server.
app.use(function(req, res, next) {
res.setHeader('X-UA-Compatible', 'IE=edge');
next();
});
For Angular 2 - 5 refer the article Multiple Environment in angular
For Angular 6 use ng serve --configuration=dev
Note: Refer the same article for angular 6 as well. But wherever you find
--env
instead use--configuration
. That's works well for angular 6.
Like @Vonc said, there is no possibility to add a command like as of now. The only workaround is to mention the folder, to create it and add contents to it.
# add contents to folder
ADD src $HOME/src
Would create a folder called src in your directory and add contents of your folder src into this.
NONE of these answers work for situations where the value name contains spaces, dots, or other characters that are reserved in PowerShell. In that case you have to wrap the name in double quotes as per http://blog.danskingdom.com/accessing-powershell-variables-with-periods-in-their-name/ - for example:
PS> Get-ItemProperty Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7
14.0 : C:\Program Files (x86)\Microsoft Visual Studio 14.0\
12.0 : C:\Program Files (x86)\Microsoft Visual Studio 12.0\
11.0 : C:\Program Files (x86)\Microsoft Visual Studio 11.0\
15.0 : C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PSPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\V
S7
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS
PSChildName : VS7
PSProvider : Microsoft.PowerShell.Core\Registry
If you want to access any of the 14.0, 12.0, 11.0, 15.0 values, the solution from the accepted answer will not work - you will get no output:
PS> (Get-ItemProperty Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7 -Name 15.0).15.0
PS>
What does work is quoting the value name, which you should probably be doing anyway for safety:
PS> (Get-ItemProperty "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7" -Name "15.0")."15.0"
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PS>
Thus, the accepted answer should be modified as such:
PS> $key = "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7"
PS> $value = "15.0"
PS> (Get-ItemProperty -Path $key -Name $value).$value
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\
PS>
This works in PowerShell 2.0 through 5.0 (although you should probably be using Get-ItemPropertyValue
in v5).

In the past (i.e. WinXP days), I used to depend/rely on DLL Dependency Walker (depends.exe) but there are times when I am still not able to determine the DLL issue(s). Ideally, we'd like to find out before runtime by inspections but if that does not resolve it (or taking too much time), you can try enabling the "loader snap" as described on http://blogs.msdn.com/b/junfeng/archive/2006/11/20/debugging-loadlibrary-failures.aspx and https://msdn.microsoft.com/en-us/library/windows/hardware/ff556886(v=vs.85).aspx and briefly mentioned LoadLibrary fails; GetLastError no help
WARNING: I've messed up my Windows in the past fooling around with gflag making it crawl to its knees, you have been forewarned.
Note: "Loader snap" is per-process so the UI enable won't stay checked (use cdb or glfags -i)
I know this is an older post, but for what it's worth, I've found that the "simplest" solution is to just right-click on the database, and select "Tasks" -> "Export Data-tier Application". It's possible that this option is only available because the server is hosted on Azure (from what I remember working with Azure in the past, the .bacpac format was quite common there).
Once that's done, you can right-click on your local server "Databases" list, and use the "Import Data-tier Application" to get the data to your local machine using the .bacpac file.
Just bear in mind the export could take a long time. Took roughly two hours for mine to finish exporting. Import part is much faster, though.

Try reducing the range of the for loop to range(len(a)-1)
:
a = [0,1,2,3]
b = []
for i in range(len(a)-1):
b.append(a[i]+a[i+1])
print(b)
This can also be written as a list comprehension:
b = [a[i] + a[i+1] for i in range(len(a)-1)]

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().
Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static
for the example. Once it's done, add this line in your server code:
app.use("/static", express.static('./static/'));
This will effectively serve every file in your "static" folder via the /static route.
Querying your index.js file in the client thus becomes:
<script src="static/index.js"></script>
Judging by the source code for URI
, the
public URL(URL context, String spec, URLStreamHandler handler)
constructor does more validation than the other constructors. You might try that one, but YMMV.
this solution work only .if your want to ignore this Warning

Okay: This is what I did now and it's solved:
My httpd-vhosts.conf
looks like this now:
<VirtualHost dropbox.local:80>
DocumentRoot "E:/Documenten/Dropbox/Dropbox/dummy-htdocs"
ServerName dropbox.local
ErrorLog "logs/dropbox.local-error.log"
CustomLog "logs/dropbox.local-access.log" combined
<Directory "E:/Documenten/Dropbox/Dropbox/dummy-htdocs">
# AllowOverride All # Deprecated
# Order Allow,Deny # Deprecated
# Allow from all # Deprecated
# --New way of doing it
Require all granted
</Directory>
</VirtualHost>
First, I saw that it's necessary to have set the <Directory xx:xx>
options. So I put the <Directory > [..] </Directory>
-part INSIDE the <VirtualHost > [..] </VirtualHost>
.
After that, I added AllowOverride AuthConfig Indexes
to the <Directory>
options.
Now http://localhost
also points to the dropbox-virtualhost. So I added dropbox.local
to <VirtualHost *:80>
which makes it as <VirtualHost dropbox.local:80>
FINALLY it works :D!
I'm a happy man! :) :)

No, I think alt
is better because the purpose of that attribute is to provide "alternate" text in the event that the image cannot be view (whether it be that the image is missing or that the browser itself is incapable of displaying it).
Do, I need to resolve all the conflicts before proceeding to next cherry -pick
Yes, at least with the standard git setup. You cannot cherry-pick while there are conflicts.
Furthermore, in general conflicts get harder to resolve the more you have, so it's generally better to resolve them one by one.
That said, you can cherry-pick multiple commits at once, which would do what you are asking for. See e.g. How to cherry-pick multiple commits . This is useful if for example some commits undo earlier commits. Then you'd want to cherry-pick all in one go, so you don't have to resolve conflicts for changes that are undone by later commits.
Further, is it suggested to do cherry-pick or branch merge in this case?
Generally, if you want to keep a feature branch up to date with main development, you just merge master -> feature branch. The main advantage is that a later merge feature branch -> master will be much less painful.
Cherry-picking is only useful if you must exclude some changes in master from your feature branch. Still, this will be painful so I'd try to avoid it.

In addition to the above answer and restarting the IDE didn't do, try restarting "Jetbrains Toolbox" if you use it, this did it for me
String.prototype.{ split, slice, substr, substring }
operate on UTF-16 encoded stringsNone of the previous answers are Unicode-aware. Strings are encoded as UTF-16 in most modern JavaScript engines, but higher Unicode code points require surrogate pairs, so older, pre-existing string methods operate on UTF-16 code units, not Unicode code points.
const string = "?";
console.log(string.slice(0, -1)); // "?\ud83e"
console.log(string.substr(0, string.length - 1)); // "?\ud83e"
console.log(string.substring(0, string.length - 1)); // "?\ud83e"
console.log(string.replace(/.$/, "")); // "?\ud83e"
console.log(string.match(/(.*).$/)[1]); // "?\ud83e"
const utf16Chars = string.split("");
utf16Chars.pop();
console.log(utf16Chars.join("")); // "?\ud83e"
_x000D_
In addition, RegExp
methods, as suggested in older answers, don’t match line breaks at the end:
const string = "Hello, world!\n";
console.log(string.replace(/.$/, "").endsWith("\n")); // true
console.log(string.match(/(.*).$/) === null); // true
_x000D_
Unicode-aware code utilizes the string’s iterator; see Array.from
and ...
spread.
string[Symbol.iterator]
can be used (e.g. instead of string
) as well.
Also see How to split Unicode string to characters in JavaScript.
Examples:
const string = "?";
console.log(Array.from(string).slice(0, -1).join("")); // "?"
console.log([
...string
].slice(0, -1).join("")); // "?"
_x000D_
s
and u
flags on a RegExp
The dotAll
or s
flag makes .
match line break characters, the unicode
or u
flag enables certain Unicode-related features.
Note that, when using the u
flag, you eliminate unnecessary identity escapes, as these are invalid in a u
regex, e.g. \[
is fine, as it would start a character class without the backslash, but \:
isn’t, as it’s a :
with or without the backslash, so you need to remove the backslash.
Examples:
const unicodeString = "?",
lineBreakString = "Hello, world!\n";
console.log(lineBreakString.replace(/.$/s, "").endsWith("\n")); // false
console.log(lineBreakString.match(/(.*).$/s) === null); // false
console.log(unicodeString.replace(/.$/su, "")); // ?
console.log(unicodeString.match(/(.*).$/su)[1]); // ?
// Now `split` can be made Unicode-aware:
const unicodeCharacterArray = unicodeString.split(/(?:)/su),
lineBreakCharacterArray = lineBreakString.split(/(?:)/su);
unicodeCharacterArray.pop();
lineBreakCharacterArray.pop();
console.log(unicodeCharacterArray.join("")); // "?"
console.log(lineBreakCharacterArray.join("").endsWith("\n")); // false
_x000D_
Note that some graphemes consist of more than one code point, e.g. ??
which consists of the sequence (U+1F3F3),
VS16
(U+FE0F), ZWJ
(U+200D), (U+1F308).
Here, even
Array.from
will split this into four “characters”.
Matching those is possible with the Unicode property escapes sequence properties proposal.
The best way to achieve what you want is to create your own wpf based control , or use a one that was made by other people
why ? because there will be a noticeable performance impact when using the winforms dialog in a wpf application (for some reason)
i recommend this project
https://opendialog.codeplex.com/
or Nuget :
PM> Install-Package OpenDialog
it's very MVVM friendly and it isn't wraping the winforms dialog
This had occurred to me and I have found out that it was because of faulty internet connection. If I use the public wifi at my place, which blocks various websites for security reasons, Mongo refuses to connect. But if I were to use my own mobile data, I can connect to the database.
You can try settings of code::block

With Git 2.23+ (August 2019), the proper command to restore files (and the index) woud be to use... git restore
(not reset --hard
or the confusing git checkout
command)
That is:
git restore -s=HEAD --staged --worktree -- .
Or its abbreviated form:
git restore -s@ -SW -- .
An abstract class is a class that contains at least one abstract method, which is a method without any actual code in it, just the name and the parameters, and that has been marked as "abstract".
The purpose of this is to provide a kind of template to inherit from and to force the inheriting class to implement the abstract methods.
An abstract class thus is something between a regular class and a pure interface. Also interfaces are a special case of abstract classes where ALL methods are abstract.
See this section of the PHP manual for further reference.
You should use the Developer App.
On the right is a section titled "My Applications" from which you can select an application to see its information.
You can also go straight here as well, which will list your apps on the left.
Define set
a = set()
Use add to append single values
a.add(1)
a.add(2)
Use update to add elements from tuples, sets, lists or frozen-sets
a.update([3,4])
>> print(a)
{1, 2, 3, 4}
If you want to add a tuple or frozen-set itself, use add
a.add((5, 6))
>> print(a)
{1, 2, 3, 4, (5, 6)}
Note: Since set elements must be hashable, and lists are considered mutable, you cannot add a list to a set. You also cannot add other sets to a set. You can however, add the elements from lists and sets as demonstrated with the ".update" method.
POSIX sh doesn't understand ==
for string equality, as that is a bash-ism. Use =
instead.
The other people saying that brackets aren't supported by sh are wrong, btw.
Note that setTimeout
and setInterval
are very different functions:
setTimeout
will execute the code once, after the timeout.setInterval
will execute the code forever, in intervals of the provided timeout.Both functions return a timer ID which you can use to abort the timeout. All you have to do is store that value in a variable and use it as argument to clearTimeout(tid)
or clearInterval(tid)
respectively.
So, depending on what you want to do, you have two valid choices:
// set timeout
var tid = setTimeout(mycode, 2000);
function mycode() {
// do some stuff...
tid = setTimeout(mycode, 2000); // repeat myself
}
function abortTimer() { // to be called when you want to stop the timer
clearTimeout(tid);
}
or
// set interval
var tid = setInterval(mycode, 2000);
function mycode() {
// do some stuff...
// no need to recall the function (it's an interval, it'll loop forever)
}
function abortTimer() { // to be called when you want to stop the timer
clearInterval(tid);
}
Both are very common ways of achieving the same.
If ECMAScript 5 support is available, you can use Object.keys()
:
function isEmpty(obj) {
return Object.keys(obj).length === 0;
}
For ES3 and older, there's no easy way to do this. You'll have to loop over the properties explicitly:
function isEmpty(obj) {
for(var prop in obj) {
if(obj.hasOwnProperty(prop))
return false;
}
return true;
}
As others have noted, Mongoose 4
supports this. It is very important to note that you can recurse deeper than one level too, if needed—though it is not noted in the docs:
Project.findOne({name: req.query.name})
.populate({
path: 'threads',
populate: {
path: 'messages',
model: 'Message',
populate: {
path: 'user',
model: 'User'
}
}
})
Same solution as @Al3x for Windows x64, in cmd.exe
:
cd %programfiles%\Oracle\VirtualBox
VBoxManage internalcommands sethduuid "full/path/to/.vdi"
This randomizes the UUID of the disk. Pro tip: Right click the .vdi file while holding shift and select "Copy as path" to obtain "full/path/to/.vdi"
and enable quick edit in cmd.exe, then right click to paste.
You can't take a screen-shot: it would be an irresponsible security risk to let you do so. However, you can:
package - takes the compiled code and package it in its distributable format, such as a JAR or WAR file. install - install the package into the local repository, for use as a dependency in other projects locally
The following command will save the SSH key on the clipboard. You only need to paste at the desired location.
cat ~/.ssh/id_rsa.pub | pbcopy
echo '

<body>
</body>
</html>
';
or
echo "<html>\n<body>\n</body>\n</html>\n";
If you're using Python 3, or appropriate Python 2.x version with from __future__ import print_function
then:
data = [7, 7, 7, 7]
print(*data, sep='')
Otherwise, you'll need to convert to string and print:
print ''.join(map(str, data))
When you have a more complex id string the double quotes are mandatory.
For example if you have an id like this: id="2.2"
, the correct way to access it is: $('input[id="2.2"]')
As much as possible use the double quotes, for safety reasons.
import matplotlib.pyplot as plt
import numpy as np
import scipy.stats as stats
import math
mu = 0
variance = 1
sigma = math.sqrt(variance)
x = np.linspace(mu - 3*sigma, mu + 3*sigma, 100)
plt.plot(x, stats.norm.pdf(x, mu, sigma))
plt.show()
If you want the correct answer according to the latest Unicode standard, you should use icu4j.
UCharacter.toTitleCase(Locale.US, "hello world", null, 0);
Note that this is locale sensitive.

If there is no selection, you can use the properties .selectionStart
or .selectionEnd
(with no selection they're equal).
var cursorPosition = $('#myTextarea').prop("selectionStart");
Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.
I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.
You could alter your CSS to render them less obtrusively, e.g.
div p,
div br {
display: inline;
}
or - as my commenter points out:
div br {
display: none;
}
but then to achieve the example of what you want, you'll need to trim the p
down, so:
div br {
display: none;
}
div p {
padding: 0;
margin: 0;
}

I went through the exercise to capture low level packet exchange, and found that network connection is only triggered by operations like getInputStream, getOutputStream, getResponseCode, getResponseMessage etc.
Here is the packet exchange captured when I try to write a small program to upload file to Dropbox.
Below is my toy program and annotation
/* Create a connection LOCAL object,
* the openConnection() function DOES NOT initiate
* any packet exchange with the remote server.
*
* The configurations only setup the LOCAL
* connection object properties.
*/
HttpURLConnection connection = (HttpURLConnection) dst.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
...//headers setup
byte[] testContent = {0x32, 0x32};
/**
* This triggers packet exchange with the remote
* server to create a link. But writing/flushing
* to a output stream does not send out any data.
*
* Payload are buffered locally.
*/
try (BufferedOutputStream outputStream = new BufferedOutputStream(connection.getOutputStream())) {
outputStream.write(testContent);
outputStream.flush();
}
/**
* Trigger payload sending to the server.
* Client get ALL responses (including response code,
* message, and content payload)
*/
int responseCode = connection.getResponseCode();
System.out.println(responseCode);
/* Here no further exchange happens with remote server, since
* the input stream content has already been buffered
* in previous step
*/
try (InputStream is = connection.getInputStream()) {
Scanner scanner = new Scanner(is);
StringBuilder stringBuilder = new StringBuilder();
while (scanner.hasNextLine()) {
stringBuilder.append(scanner.nextLine()).append(System.lineSeparator());
}
}
/**
* Trigger the disconnection from the server.
*/
String responsemsg = connection.getResponseMessage();
System.out.println(responsemsg);
connection.disconnect();
If you have objects, not structs (or strings), then you'll have to intersect their keys first, and then select objects by those keys:
var ids = list1.Select(x => x.Id).Intersect(list2.Select(x => x.Id));
var result = list1.Where(x => ids.Contains(x.Id));
I've used both but in massive complex procedures have always found temp tables better to work with and more methodical. CTEs have their uses but generally with small data.
For example I've created sprocs that come back with results of large calculations in 15 seconds yet convert this code to run in a CTE and have seen it run in excess of 8 minutes to achieve the same results.
If your GridView is databond, make an index column in the resultset you retrive like this:
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
In the command control you want to use make the value of CommandArgument property equal to the row index of the DataSet table RowIndex like this:
<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />
Use the OnRowCommand event to fire on clicking the link button like this:
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
Finally the code behind you can then do whatever you like when the event is triggered like this:
protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
if(pnlMsgBody.Visible == false)
{
pnlMsgBody.Visible = true;
}
else
{
pnlMsgBody.Visible = false;
}
}
I'd say that the main rule of thumb is not to roll your own. Try to use something that has been thoroughly tested, e.g., SHA-1 or something along those lines.
I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:
$(".bgHeaderH2").text();
Use cd
in a subshell; the shorthand way to use this kind of subshell is parentheses.
(cd wherever; mycommand ...)
That said, if your command has an environment that it requires, it should really ensure that environment itself instead of putting the onus on anything that might want to use it (unless it's an internal command used in very specific circumstances in the context of a well defined larger system, such that any caller already needs to ensure the environment it requires). Usually this would be some kind of shell script wrapper.
Three options demonstrated. I prefer to find the third as the most concise.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.
The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.
You can load data from a csv or text file. If you have a text file with records from a table, you can load those records within the table. For example if you have a text file, where each row is a record with the values for each column, you can load the records this way.
id //field 1
name //field2
1,peter
2,daniel
...
--example on windows
LOAD DATA LOCAL INFILE 'C:\\directory_example\\table.txt'
INTO TABLE Table
CHARACTER SET UTF8
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n';
You can get the device screen width via the screen.width property.
Sometimes it's also useful to use window.innerWidth (not typically found on mobile devices) instead of screen width when dealing with desktop browsers where the window size is often less than the device screen size.
Typically, when dealing with mobile devices AND desktop browsers I use the following:
var width = (window.innerWidth > 0) ? window.innerWidth : screen.width;
You can also read up on the ILIKE
keyword. It can be quite useful at times, albeit it does not conform to the SQL standard. See here for more information: http://www.postgresql.org/docs/9.2/static/functions-matching.html
I found this way to be a good one, without having to worry too much about charsets and arrays, or iconv:
function replace_accents($str) {
$str = htmlentities($str, ENT_COMPAT, "UTF-8");
$str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring);/','$1',$str);
return html_entity_decode($str);
}
Bower uses semver syntax, but here are a few quick examples:
You can install a specific version:
$ bower install jquery#1.11.1
You can use ~ to specify 'any version that starts with this':
$ bower install jquery#~1.11
You can specify multiple version requirements together:
$ bower install "jquery#<2.0 >1.10"
If its a Java
version problem, you can edit the eclipse.ini
file and assign the compatible version to the application through adding these lines:
windows example:
-vm
C:\jdk1.7.0_21\bin\javaw.exe
