Eg:
Datatable newTable = new DataTable();
foreach(string s1 in list)
{
if (s1 != string.Empty) {
dvProducts.RowFilter = "(CODE like '" + serachText + "*') AND (CODE <> '" + s1 + "')";
foreach(DataRow dr in dvProducts.ToTable().Rows)
{
newTable.ImportRow(dr);
}
}
}
ListView1.DataSource = newTable;
ListView1.DataBind();
For those of you how have implemented the checked answer yet still getting the error
(Object reference not set to an instance of an object)
As was mentioned in the comments, maybe the DataGridView's data source is not of the type DataTable, but if it is, try to assign the data table to the DataGridView's data source again. In my case, I assigned the data table to the DataGridView in FormLoad() and when I write this code
(dataGridViewFields.DataSource as DataTable).DefaultView.RowFilter = string.Format("Field = '{0}'", textBoxFilter.Text);
it was giving me the error I mentioned above. So, I reassigned the data table to the dgv again. So the code was something like
dataGridViewFields.DataSource = Dt;
(dataGridViewFields.DataSource as DataTable).DefaultView.RowFilter = string.Format("Field = '{0}'", textBoxFilter.Text);
And it worked.
BEGIN...END works, you just have to add a commented section. The easiest way to do this is to add a section name! Another route is to add a comment block. See below:
BEGIN -- Section Name
/*
Comment block some stuff --end comment should be on next line
*/
--Very long query
SELECT * FROM FOO
SELECT * FROM BAR
END
The best answer is not the correct way to do this :(. You actually bound indexPath with model, which is not always good. Imagine that some rows has been added during loading image. Now cell for given indexPath exists on screen, but the image is no longer correct! The situation is kinda unlikely and hard to replicate but it's possible.
It's better to use MVVM approach, bind cell with viewModel in controller and load image in viewModel (assigning ReactiveCocoa signal with switchToLatest method), then subscribe this signal and assign image to cell! ;)
You have to remember to not abuse MVVM. Views have to be dead simple! Whereas ViewModels should be reusable! It's why it's very important to bind View (UITableViewCell) and ViewModel in controller.

In case you want to clone a specific branch only, then,
git clone -b <branch-name> <repo-url> <destination-folder-name>
for example,
git clone -b dev https://github.com/sferik/sign-in-with-twitter.git signin

Additional comments to mti2935 good answer.
It seems the higher iteration the better protection against brute force, and you should use a high iteration as you can afford performance/resource wise.
On my my old Intel i3-7100 encrypting a rather big file 1.5GB:
time openssl enc -aes256 -e -pbkdf2 -iter 10000 -pass pass:"mypassword" -in "InputFile" -out "OutputFile"
Seconds: 2,564s
time openssl enc -aes256 -e -pbkdf2 -iter 262144 -pass pass:"mypassword" -in "InputFile" -out "OutputFile"
Seconds: 2,775s
Not really any difference, didn't check memory usage though(?)
With today's GPUs, and even faster tomorrows, I guess billion brute-force iteration seems possible every seconds.
12 years ago a NVIDIA GeForce 8800 Ultra
could iterate over 200.000 millions/sec iterations (MD5 hashing though)

Just to add my results, also using Matplotlib.
.eps made all my text bold and removed transparency. .svg gave me high-resolution pictures that actually looked like my graph.
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# Do the plot code
fig.savefig('myimage.svg', format='svg', dpi=1200)
I used 1200 dpi because a lot of scientific journals require images in 1200 / 600 / 300 dpi, depending on what the image is of. Convert to desired dpi and format in GIMP or Inkscape.
Obviously the dpi doesn't matter since .svg are vector graphics and have "infinite resolution".
As most of the answers have pointed out, using the IP address 127.0.0.1 over "localhost" will sometimes help the slowness issue - but this isn't really a solution because it does not fix the underlining problem.
What makes this problem hard (and hit-and-miss), is it can be caused by about a dozen different things between the OS, the WAMP configuration, and your Browser.
Remove ::1 localhost
from your Windows hosts file, and make sure 127.0.0.1 localhost
is present. You want your request to go directly to the listening IPv4 socket.
Disable IPv6 on your system. You are most likely not using it, and it has been known to cause all kinds of issues.
Exclude your Apache and MySQL binary paths, and the Database folder, from your firewall and anti-virus software. They will interfere and slow things down.
Reset your TCP/IP sub-system and reboot: netsh int ip reset c:\resetlog.txt
Make sure your system is not using stale DNS servers: ipconfig /all
Flush Windows DNS cache: ipconfig /flushdns
Clear your Browser's Cache.
A little more in-depth is this guide: WAMP is Running Very Slow
SELECT name

None
is just a value that commonly is used to signify 'empty', or 'no value here'. It is a signal object; it only has meaning because the Python documentation says it has that meaning.
There is only one copy of that object in a given Python interpreter session.
If you write a function, and that function doesn't use an explicit return
statement, None
is returned instead, for example. That way, programming with functions is much simplified; a function always returns something, even if it is only that one None
object.
You can test for it explicitly:
if foo is None:
# foo is set to None
if bar is not None:
# bar is set to something *other* than None
Another use is to give optional parameters to functions an 'empty' default:
def spam(foo=None):
if foo is not None:
# foo was specified, do something clever!
The function spam()
has a optional argument; if you call spam()
without specifying it, the default value None
is given to it, making it easy to detect if the function was called with an argument or not.
Other languages have similar concepts. SQL has NULL
; JavaScript has undefined
and null
, etc.
Note that in Python, variables exist by virtue of being used. You don't need to declare a variable first, so there are no really empty variables in Python. Setting a variable to None
is then not the same thing as setting it to a default empty value; None
is a value too, albeit one that is often used to signal emptyness. The book you are reading is misleading on that point.
It is up to you. Just use the commit message as you wish. But it is easier if you are not switching between times and languages.
And if you develop in a team - it should be discussed and set fixed.
Working in swift 3.0 For changing the title color you need to add titleTextAttributes like this
let textAttributes = [NSForegroundColorAttributeName:UIColor.white]
self.navigationController.navigationBar.titleTextAttributes = textAttributes
For changing navigationBar background color you can use this
self.navigationController.navigationBar.barTintColor = UIColor.white
For changing navigationBar back title and back arrow color you can use this
self.navigationController.navigationBar.tintColor = UIColor.white
var filename = fullPath.replace(/^.*[\\\/]/, '')
This will handle both \ OR / in paths

You can find last character using php many ways like substr() and mb_substr().
If you’re using multibyte character encodings like UTF-8, use mb_substr instead of substr
Here i can show you both example:
<?php
echo substr("testers", -1);
echo mb_substr("testers", -1);
?>
body{
background-image: url('../img/bg.png');
}
I tried this on my project where I need to set the background image of a div so I used this and it worked!
conda create -n py37 -c anaconda anaconda=5.3
seems to be working.
You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).
Your code could be like:
const myArray = [
{
"id":25,
"name":"Anakin Skywalker",
"createdAt":"2017-04-12T12:48:55.000Z",
"updatedAt":"2017-04-12T12:48:55.000Z"
},
{
"id":1,
"name":"Luke Skywalker",
"createdAt":"2017-04-12T11:25:03.000Z",
"updatedAt":"2017-04-12T11:25:03.000Z"
}
]
const myOrderedArray = _.sortBy(myArray, o => o.name)
As discussed somewhat in the question comments, this is one way you could do it:
<input ... ng-model="$parent.storeDefault" value="{{location.id}}">
The above assumes that each location has a field (e.g., id) that holds a unique value.
Note that $parent.storeDefault is used because ng-repeat creates a child scope, and we want to manipulate the storeDefault parameter on the parent scope.
import ImageGrab
img = ImageGrab.grab()

Another solution would be to create a helper class How to Create helper classes here
class Helper{
public static function format_message($message,$type)
{
return '<p class="alert alert-'.$type.'">'.$message.'</p>'
}
}
Then you can do this.
Redirect::to('users/login')->with('message', Helper::format_message('A bla blah occured','error'));
or
Redirect::to('users/login')->with('message', Helper::format_message('Thanks for registering!','info'));
and in your view
@if(Session::has('message'))
{{Session::get('message')}}
@endif
Assuming you actually mean timestamp
because there is no datetime
in Postgres
Cast the timestamp column to a date, that will remove the time part:
select *
from the_table
where the_timestamp_column::date = date '2015-07-15';
This will return all rows from July, 15th.
Note that the above will not use an index on the_timestamp_column
. If performance is critical, you need to either create an index on that expression or use a range condition:
select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
and the_timestamp_column < timestamp '2015-07-16 00:00:00';

What you (probably want) are Flex 2.5.4 (some people are now "maintaining" it and producing newer versions, but IMO they've done more to screw it up than fix any real shortcomings) and byacc 1.9 (likewise). (Edit 2017-11-17: Flex 2.5.4 is not available on Sourceforge any more, and the Flex github repository only goes back to 2.5.5. But you can apparently still get it from a Gnu ftp server at ftp://ftp.gnu.org/old-gnu/gnu-0.2/src/flex-2.5.4.tar.gz.)
Since it'll inevitably be recommended, I'll warn against using Bison. Bison was originally written by Robert Corbett, the same guy who later wrote Byacc, and he openly states that at the time he didn't really know or understand what he was doing. Unfortunately, being young and foolish, he released it under the GPL and now the GPL fans push it as the answer to life's ills even though its own author basically says it should be thought of as essentially a beta test product -- but by the convoluted reasoning of GPL fans, byacc's license doesn't have enough restrictions to qualify as "free"!
If you want to cater to 1-word cell, use this... based upon astander's

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.
Data Used
This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.
Below is the implementation.
import numpy as np import cv2 # Read the image image = cv2.imread( 'digits.png' ) # gray scale conversion gray_img = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # We will divide the image # into 5000 small dimensions # of size 20x20 divisions = list (np.hsplit(i, 100 ) for i in np.vsplit(gray_img, 50 )) # Convert into Numpy array # of size (50,100,20,20) NP_array = np.array(divisions) # Preparing train_data # and test_data. # Size will be (2500,20x20) train_data = NP_array[:,: 50 ].reshape( - 1 , 400 ).astype(np.float32) # Size will be (2500,20x20) test_data = NP_array[:, 50 : 100 ].reshape( - 1 , 400 ).astype(np.float32) # Create 10 different labels # for each type of digit k = np.arange( 10 ) train_labels = np.repeat(k, 250 )[:,np.newaxis] test_labels = np.repeat(k, 250 )[:,np.newaxis] # Initiate kNN classifier knn = cv2.ml.KNearest_create() # perform training of data knn.train(train_data, cv2.ml.ROW_SAMPLE, train_labels) # obtain the output from the # classifier by specifying the # number of neighbors. ret, output ,neighbours, distance = knn.findNearest(test_data, k = 3 ) # Check the performance and # accuracy of the classifier. # Compare the output with test_labels # to find out how many are wrong. matched = output = = test_labels correct_OP = np.count_nonzero(matched) #Calculate the accuracy. accuracy = (correct_OP * 100.0 ) / (output.size) # Display accuracy. print (accuracy) |

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).
1) My first question was about letter_recognition.data
file that comes with OpenCV samples. I wanted to know what is inside that file.
It contains a letter, along with 16 features of that letter.
And this SOF
helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers
.
(Although I didn't understand some of the features at the end)
2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.
So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)
I took the below image for my training data:
(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).
To prepare the data for training, I made a small code in OpenCV. It does the following things:
key press manually
. This time we press the digit key ourselves corresponding to the letter in the box..txt
files.At the end of the manual classification of digits, all the digits in the training data (train.png
) are labeled manually by ourselves, image will look like below:
Below is the code I used for the above purpose (of course, not so clean):
import sys
import numpy as np
import cv2
im = cv2.imread('pitrain.png')
im3 = im.copy()
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)
################# Now finding Contours ###################
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
samples = np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
cv2.imshow('norm',im)
key = cv2.waitKey(0)
if key == 27: # (escape to quit)
sys.exit()
elif key in keys:
responses.append(int(chr(key)))
sample = roismall.reshape((1,100))
samples = np.append(samples,sample,0)
responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"
np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)
Now we enter in to training and testing part.
For the testing part, I used the below image, which has the same type of letters I used for the training phase.
For training we do as follows:
.txt
files we already saved earlierFor testing purposes, we do as follows:
I included last two steps (training and testing) in single code below:
import cv2
import numpy as np
####### training part ###############
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))
model = cv2.KNearest()
model.train(samples,responses)
############################# testing part #########################
im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)
contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)
for cnt in contours:
if cv2.contourArea(cnt)>50:
[x,y,w,h] = cv2.boundingRect(cnt)
if h>28:
cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
roi = thresh[y:y+h,x:x+w]
roismall = cv2.resize(roi,(10,10))
roismall = roismall.reshape((1,100))
roismall = np.float32(roismall)
retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
string = str(int((results[0][0])))
cv2.putText(out,string,(x,y+h),0,1,(0,255,0))
cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)
And it worked, below is the result I got:
Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.
But anyway, this is a good start to go for beginners (I hope so).
This worked for me in Kotlin class
fun hideKeyboard(activity: Activity) {
try {
val inputManager = activity
.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val currentFocusedView = activity.currentFocus
if (currentFocusedView != null) {
inputManager.hideSoftInputFromWindow(currentFocusedView.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
Assuming that this is about OAuth 2.0 since it is about JWTs and refresh tokens...:
just like an access token, in principle a refresh token can be anything including all of the options you describe; a JWT could be used when the Authorization Server wants to be stateless or wants to enforce some sort of "proof-of-possession" semantics on to the client presenting it; note that a refresh token differs from an access token in that it is not presented to a Resource Server but only to the Authorization Server that issued it in the first place, so the self-contained validation optimization for JWTs-as-access-tokens does not hold for refresh tokens
that depends on the security/access of the database; if the database can be accessed by other parties/servers/applications/users, then yes (but your mileage may vary with where and how you store the encryption key...)
an Authorization Server may issue both access tokens and refresh tokens at the same time, depending on the grant that is used by the client to obtain them; the spec contains the details and options on each of the standardized grants
I've resolved the issue, by going to setting and permalink, just choose post-name.
it should work and you'll see the exact page.. rather than dashboard/xampp page again

Just an performance comparement on openjdk 13, Windows 10. For each of theese texts:
"abcd"
" "
" \r\n\t"
" ab "
" \n\n\r\t \n\r\t\t\t \r\n\r\n\r\t \t\t\t\r\n\n"
"lorem ipsum dolor sit amet consectetur adipisici elit"
"1234657891234567891324569871234567891326987132654798"
executed one of following tests:
// trim + empty
input.trim().isEmpty()
// simple match
input.matches("\\S")
// match with precompiled pattern
final Pattern PATTERN = Pattern.compile("\\S");
PATTERN.matcher(input).matches()
// java 11's isBlank
input.isBlank()
each 10.000.000 times.
The results:
METHOD min max note
trim: 18 313 much slower if text not trimmed
match: 1799 2010
pattern: 571 662
isBlank: 60 338 faster the earlier hits the first non-whitespace character
Quite surprisingly the trim+empty is the fastest. Even if it needs to construct the trimmed text. Still faster then simple for-loop looking for one single non-whitespaced character...
EDIT: The longer text, the more numbers differs. Trim of long text takes longer time than just simple loop. However, the regexs are still the slowest solution.
Query syntax
var query = from p in context.People
group p by p.name into g
select new
{
name = g.Key,
count = g.Count()
};
Method syntax
var query = context.People
.GroupBy(p => p.name)
.Select(g => new { name = g.Key, count = g.Count() });
for (Map.Entry<String, ArrayList<Integer>> entry : map.entrySet()) {
System.out.println( entry.getKey());
System.out.println( entry.getValue());//Returns the list of values
}
You just need to do it in correct syntax. Let me give you a minimal example I just did with Python interactive shell:
>>> class MyNameClass():
... def __init__(self, myname):
... print myname
...
>>> p1 = MyNameClass('John')

You're calling both wait
and notifyAll
without using a synchronized
block. In both cases the calling thread must own the lock on the monitor you call the method on.
From the docs for notify
(wait
and notifyAll
have similar documentation but refer to notify
for the fullest description):
This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:
- By executing a synchronized instance method of that object.
- By executing the body of a synchronized statement that synchronizes on the object.
- For objects of type Class, by executing a synchronized static method of that class.
Only one thread at a time can own an object's monitor.
Only one thread will be able to actually exit wait
at a time after notifyAll
as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.

I had the same problem with a dummy app that happened to have the same name as my final app and couldn't publish because the App Name is already in use
To fix it, instead of deleting it(which you can't) I just changed the name of the dummy app to something random and hit SAVE. Then I was able to add the new app with the proper name
Wrong method was used for errors, here is the working code:
BufferedReader br = null;

br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
} else {
br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));

NoClassDefFound error is a nebulous error and is often hiding a more serious issue. It is not the same as ClassNotFoundException (which is thrown when the class is just plain not there).
NoClassDefFound may indicate the class is not there, as the javadocs indicate, but it is typically thrown when, after the classloader has loaded the bytes for the class and calls "defineClass" on them. Also carefully check your full stack trace for other clues or possible "cause" Exceptions (though your particular backtrace shows none).
The first place to look when you get a NoClassDefFoundError is in the static bits of your class i.e. any initialization that takes place during the defining of the class. If this fails it will throw a NoClassDefFoundError - it's supposed to throw an ExceptionInInitializerError and indicate the details of the problem but in my experience, these are rare. It will only do the ExceptionInInitializerError the first time it tries to define the class, after that it will just throw NoClassDefFound. So look at earlier logs.
I would thus suggest looking at the code in that HibernateTransactionInterceptor line and seeing what it is requiring. It seems that it is unable to define the class SpringFactory. So maybe check the initialization code in that class, that might help. If you can debug it, stop it at the last line above (17) and debug into so you can try find the exact line that is causing the exception. Also check higher up in the log, if you very lucky there might be an ExceptionInInitializerError.
Just add this in the .htaccess file:
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]
The easiest way to solve this problem is just to move your`s project to another folder and import it. This is because you have already had this project(or project with the same name) in that folder. And when you delete project, eclipse still retains a reference to it
Ran into this today at work. An admin thought it prudent to hard code Python 2.7 as the PYSPARK_PYTHON
and PYSPARK_DRIVER_PYTHON
in $SPARK_HOME/conf/spark-env.sh
. Needless to say this broke all of our jobs that utilize any other python versions or environments (which is > 90% of our jobs). @PhillipStich points out correctly that you may not always have write permissions for this file, as is our case. While setting the configuration in the spark-submit
call is an option, another alternative (when running in yarn/cluster mode) is to set the SPARK_CONF_DIR
environment variable to point to another configuration script. There you could set your PYSPARK_PYTHON and any other options you may need. A template can be found in the spark-env.sh source code on github.
According to MSDN maxAllowedContentLength
has type uint
, its maximum value is 4,294,967,295 bytes = 3,99 gb
So it should work fine.
See also Request Limits article. Does IIS return one of these errors when the appropriate section is not configured at all?

I had this issue with Java and Postgres. I fixed it by updating a new Connector-J version.
postgresql-9.2-1002.jdbc4.jar
https://jdbc.postgresql.org/download.html: Version 42.2.12
It seems like Github has changed their layout since you posted this question. I just created a repository and it used to give you instructions on screen. It appears they have changed that approach.
Here is the information they used to give on repo creation:
You can find a complete and very simple java class for sending emails using Google(gmail) account here, Send email message using java application
It uses following properties

The $(document).ready mechanism is meant to fire after the DOM has been loaded successfully but makes no guarantees as to the state of the images referenced by the page.
When in doubt, fall back on the good ol' window.onload event:
window.onload = function()
{
//your code here
};
Now, this is obviously slower than the jQuery approach. However, you can compromise somewhere in between:
$(document).ready
(
function()
{
var img = document.getElementById("myImage");
var intervalId = setInterval(
function()
{
if(img.complete)
{
clearInterval(intervalId);
//now we can start rotating the header
}
},
50);
}
);
To explain a bit:
we grab the DOM element of the image whose image we want completely loaded
we then set an interval to fire every 50 milliseconds.
if, during one of these intervals, the complete attribute of this image is set to true, the interval is cleared and the rotate operation is safe to start.
PyDub (http://pydub.com/) has not been mentioned and that should be fixed. IMO this is the most comprehensive library for reading audio files in Python right now, although not without its faults. Reading a wav file:
from pydub import AudioSegment
audio_file = AudioSegment.from_wav('path_to.wav')
# or
audio_file = AudioSegment.from_file('path_to.wav')
# do whatever you want with the audio, change bitrate, export, convert, read info, etc.
# Check out the API docs http://pydub.com/
PS. The example is about reading a wav file, but PyDub can handle a lot of various formats out of the box. The caveat is that it's based on both native Python wav support and ffmpeg, so you have to have ffmpeg installed and a lot of the pydub capabilities rely on the ffmpeg version. Usually if ffmpeg can do it, so can pydub (which is quite powerful).

Try
alter table company drop constraint Company_CountryID_FK
alter table company drop column CountryID
Following line in above code is not working
DB_PASSWORD=$(eval echo ${DB_PASSWORD} | base64 --decode)
Correct line is:
DB_PASSWORD=`echo $PASSWORD|base64 -d`
And save the password in other file as PASSWORD.
The correct options are (in increasing order of recommendation):
# Single POSIX test command with -o operator (not recommended anymore).
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 -o "$stats" -eq 0 ]
# Two POSIX test commands joined in a list with ||.
# Quotes strongly recommended to guard against empty or undefined variables.
while [ "$stats" -gt 300 ] || [ "$stats" -eq 0 ]
# Two bash conditional expressions joined in a list with ||.
while [[ $stats -gt 300 ]] || [[ $stats -eq 0 ]]
# A single bash conditional expression with the || operator.
while [[ $stats -gt 300 || $stats -eq 0 ]]
# Two bash arithmetic expressions joined in a list with ||.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 )) || (( stats == 0 ))
# And finally, a single bash arithmetic expression with the || operator.
# $ optional, as a string can only be interpreted as a variable
while (( stats > 300 || stats == 0 ))
Some notes:
Quoting the parameter expansions inside [[ ... ]]
and ((...))
is optional; if the variable is not set, -gt
and -eq
will assume a value of 0.
Using $
is optional inside (( ... ))
, but using it can help avoid unintentional errors. If stats
isn't set, then (( stats > 300 ))
will assume stats == 0
, but (( $stats > 300 ))
will produce a syntax error.
convert it into python datetime object if it isn't already. then add deltatime
one_years_later = Your_date + datetime.timedelta(days=(years*days_per_year))
for your case days=365.
you can have condition to check if the year is leap or no and adjust days accordingly
you can add as many years as you want
There's some sort of bogus character at the end of that source. Try deleting the last line and adding it back.
I can't figure out exactly what's there, yet ...
edit — I think it's a zero-width space, Unicode 200B. Seems pretty weird and I can't be sure of course that it's not a Stackoverflow artifact, but when I copy/paste that last function including the complete last line into the Chrome console, I get your error.
A notorious source of such characters are websites like jsfiddle. I'm not saying that there's anything wrong with them — it's just a side-effect of something, maybe the use of content-editable input widgets.
If you suspect you've got a case of this ailment, and you're on MacOS or Linux/Unix, the od
command line tool can show you (albeit in a fairly ugly way) the numeric values in the characters of the source code file. Some IDEs and editors can show "funny" characters as well. Note that such characters aren't always a problem. It's perfectly OK (in most reasonable programming languages, anyway) for there to be embedded Unicode characters in string constants, for example. The problems start happening when the language parser encounters the characters when it doesn't expect them.
$time = strtotime(date('2016-02-03 12:00:00'));
echo date("H:i:s",strtotime("-30 minutes", $time));
You can add an event listener with 'ended' as first param
Like this :
<video src="video.ogv" id="myVideo">
video not supported
</video>
<script type='text/javascript'>
document.getElementById('myVideo').addEventListener('ended',myHandler,false);
function myHandler(e) {
// What you want to do after the event
}
</script>
Disable JetBrains Inspections and get the ESLint plugin.
The only thing that File | Invalidate caches and restart
does for me is reset it long enough to trick me into thinking the error is gone. Once the inspections run again the error comes back like a gift that keeps on giving.
I saved myself all that frustration by disabling all JetBrains inspections (Editor
> Inspections
> uncheck JavaScript
) Then I installed the ESLint plugin.
The inspection that causes "Unresolved function method" can be turned off by going to JetBrains inspections (Editor
> Inspections
> JavaScript
) and searching for "Unresolved Javascript" and turning off "Unresolved Javascript function" and "Unresolved Javascript variable"
I killed them all and have edited my code hassle free ever since.
How about \A[a-z]*Id\z
? [This makes characters before Id
optional. Use \A[a-z]+Id\z
if there needs to be one or more characters preceding Id
.]
Use backticks for system commands, which helps to store their results into Perl variables.
my $pid = 5892;
my $not = ``top -H -p $pid -n 1 | grep myprocess | wc -l`;
print "not = $not\n";
df['year_month']=df.datetime_column.apply(lambda x: str(x)[:7])
This worked fine for me, didn't think pandas would interpret the resultant string date as date, but when i did the plot, it knew very well my agenda and the string year_month where ordered properly... gotta love pandas!
There are many ways to hide all elements which has certain class in javascript one way is to using for loop but here i want to show you other ways to doing it.
1.forEach and querySelectorAll('.classname')
document.querySelectorAll('.classname').forEach(function(el) {
el.style.display = 'none';
});
2.for...of with getElementsByClassName
for (let element of document.getElementsByClassName("classname")){
element.style.display="none";
}
3.Array.protoype.forEach getElementsByClassName
Array.prototype.forEach.call(document.getElementsByClassName("classname"), function(el) {
// Do something amazing below
el.style.display = 'none';
});
4.[ ].forEach and getElementsByClassName
[].forEach.call(document.getElementsByClassName("classname"), function (el) {
el.style.display = 'none';
});
i have shown some of the possible ways, there are also more ways to do it, but from above list you can Pick whichever suits and easy for you.
Note: all above methods are supported in modern browsers but may be some of them will not work in old age browsers like internet explorer.
List<T>.Add
adds a single element. Instead, use List<T>.AddRange
to add multiple values.
Additionally, List<T>.AddRange
takes an IEnumerable<T>
, so you don't need to convert tripDetails
into a List<TripDetails>
, you can pass it directly, e.g.:
tripDetailsCollection.AddRange(tripDetails);
This is the solution but you have to set:
echo 1 > /proc/sys/vm/overcommit_memory
Did you try the ||
operator ?
erm it does work? I've just tested it?

Using two of the above postings by x64igor and Phil Haselden solved this:
1. x64igor gave the example to do the Logout:
You first need to Clear the Authentication Cookie and Session Cookie by passing back empty cookies in the Response to the Logout.
public ActionResult LogOff()
{
FormsAuthentication.SignOut();
Session.Clear(); // This may not be needed -- but can't hurt
Session.Abandon();
// Clear authentication cookie
HttpCookie rFormsCookie = new HttpCookie( FormsAuthentication.FormsCookieName, "" );
rFormsCookie.Expires = DateTime.Now.AddYears( -1 );
Response.Cookies.Add( rFormsCookie );
// Clear session cookie
HttpCookie rSessionCookie = new HttpCookie( "ASP.NET_SessionId", "" );
rSessionCookie.Expires = DateTime.Now.AddYears( -1 );
Response.Cookies.Add( rSessionCookie );
2. Phil Haselden gave the example above of how to prevent caching after logout:
You need to Invalidate the Cache on the Client Side via the Response.
// Invalidate the Cache on the Client Side
Response.Cache.SetCacheability( HttpCacheability.NoCache );
Response.Cache.SetNoStore();
// Redirect to the Home Page (that should be intercepted and redirected to the Login Page first)
return RedirectToAction( "Index", "Home" );
}
You can use DataFrame.fillna
or Series.fillna
which will replace the Python object None
, not the string 'None'
.
import pandas as pd
import numpy as np
For dataframe:
df = df.fillna(value=np.nan)
For column or series:
df.mycol.fillna(value=np.nan, inplace=True)
Merge them in two steps, df1
and df2
first, and then the result of that to df3
.
In [33]: s1 = pd.merge(df1, df2, how='left', on=['Year', 'Week', 'Colour'])
I dropped year from df3 since you don't need it for the last join.
In [39]: df = pd.merge(s1, df3[['Week', 'Colour', 'Val3']],
how='left', on=['Week', 'Colour'])
In [40]: df
Out[40]:
Year Week Colour Val1 Val2 Val3
0 2014 A Red 50 NaN NaN
1 2014 B Red 60 NaN 60
2 2014 B Black 70 100 10
3 2014 C Red 10 20 NaN
4 2014 D Green 20 NaN 20
[5 rows x 6 columns]
I am giving a generic example for better understanding, In the following code
render(){
return(
<div>
<h3>Simple Counter</h3>
<Counter
value={this.props.counter}
onIncrement={this.props.increment()} <------ calling the function
onDecrement={this.props.decrement()} <-----------
onIncrementAsync={this.props.incrementAsync()} />
</div>
)
}
When supplying props I am calling the function directly, this wold have a infinite loop execution and would give you that error, Remove the function call everything works normally.
render(){
return(
<div>
<h3>Simple Counter</h3>
<Counter
value={this.props.counter}
onIncrement={this.props.increment} <------ function call removed
onDecrement={this.props.decrement} <-----------
onIncrementAsync={this.props.incrementAsync} />
</div>
)
}
first of all you shouldn't write for (int k = 0; k **<** data.length **- 1**; k++)
because the < is until the k is smaller the length -1 and then the loop will run until the last position in the array and won't get the last place in the array;
so you can fix it by two ways:
1: for (int k = 0; k <= data.length - 1; k++)
2: for (int k = 0; k < data.length; k++)
and then it will work fine!!!
and to swap you can use: to keep one of the int's in another place and then to replace
int x = data[k]
data[k] = data[data.length - 1]
data[data.length - 1] = x;
because you don't want to lose one of the int's!!
If it's a really big hex string beyond the capacity of the normal integer:
For .NET 3.5, we can use BouncyCastle's BigInteger class:
String hex = "68c7b05d0000000002f8";
// results in "494809724602834812404472"
String decimal = new Org.BouncyCastle.Math.BigInteger(hex, 16).ToString();
.NET 4.0 has the BigInteger class.
::ng-deep

and /deep/
disable view encapsulation for specific CSS rules, in other words, it gives you access to DOM elements, which are not in your component's HTML. For example, if you're using Angular Material (or any other third-party library like this), some generated elements are outside of your component's area (such as dialog) and you can't access those elements directly or using a regular CSS way. If you want to change the styles of those elements, you can use one of those three things, for example:
::ng-deep .mat-dialog {
/* styles here */
}
For now Angular team recommends making "deep" manipulations only with EMULATED view encapsulation.
"deep" manipulations are actually deprecated too, BUT it stills working for now, because Angular does pre-processing support (don't rush to refuse ::ng-deep
today, take a look at deprecation practices first).
Anyway, before following this way, I recommend you to take a look at disabling view encapsulation approach (which is not ideal too, it allows your styles to leak into other components), but in some cases, it's a better way. If you decided to disable view encapsulation, it's strongly recommended to use specific classes to avoid CSS rules intersection, and finally, avoid a mess in your stylesheets. It's really easy to disable right in the component's .ts
file:
@Component({
selector: '',
template: '',
styles: [''],
encapsulation: ViewEncapsulation.None // Use to disable CSS Encapsulation for this component
})
You can find more info about the view encapsulation in this article.
Use border-collapse and border-spacing to get spaces between the table cells. I would not recommend using floating cells as suggested by QQping.
With BigDecimal:
long aLong = ...;
int anInt = new BigDecimal(aLong).intValueExact(); // throws ArithmeticException

Per this answer:
fetch('https://code.jquery.com/jquery-latest.min.js').then(r => r.text()).then(r => eval(r))
For some reason I have to execute it twice to get the new '$' (which I have to do with the other methods as well), but it works.
This is the equivalent if your browser isn't so modern:
fetch('http://code.jquery.com/jquery-latest.min.js').then(function(r){return r.text()}).then(function(r){eval(r)})
Your statement matches any string that contains a letter or digit anywhere, even if it contains other non-alphanumeric characters. Try this:
SELECT * FROM table WHERE column REGEXP '^[A-Za-z0-9]+$';
^
and $
require the entire string to match rather than just any portion of it, and +
looks for 1 or more alphanumberic characters.
You could also use a named character class if you prefer:
SELECT * FROM table WHERE column REGEXP '^[[:alnum:]]+$';
The Visual Studio debugger comes with four standard visualizers. These are the text, HTML, and XML visualizers, all of which work on string objects, and the dataset visualizer, which works for DataSet, DataView, and DataTable objects.
To use it, break into your code, mouse over your DataSet, expand the quick watch, view the Tables, expand that, then view Table[0] (for example). You will see something like {Table1} in the quick watch, but notice that there is also a magnifying glass icon. Click on that icon and your DataTable will open up in a grid view.
You could try something like this:
(pattern1.*pattern2|pattern2.*pattern1)
You can use the function outer()
to generate it.
Have a look at the demo for the function persp()
, which is a base graphics function to draw perspective plots for surfaces.
Here is their first example:
x <- seq(-10, 10, length.out = 50)
y <- x
rotsinc <- function(x,y) {
sinc <- function(x) { y <- sin(x)/x ; y[is.na(y)] <- 1; y }
10 * sinc( sqrt(x^2+y^2) )
}
z <- outer(x, y, rotsinc)
persp(x, y, z)
The same applies to surface3d()
:
require(rgl)
surface3d(x, y, z)
One more trick, search photos by hashtags:
GET https://www.instagram.com/graphql/query/?query_hash=3e7706b09c6184d5eafd8b032dbcf487&variables={"tag_name":"nature","first":25,"after":""}
Where:
query_hash
- permanent value(i belive its hash of 17888483320059182, can be changed in future)
tag_name
- the title speaks for itself
first
- amount of items to get (I do not know why, but this value does not work as expected. The actual number of returned photos is slightly larger than the value multiplied by 4.5 (about 110 for the value 25, and about 460 for the value 100))
after
- id of the last item if you want to get items from that id. Value of end_cursor
from JSON response can be used here.
#include <stdio.h>
int main() {
printf("gcc version: %d.%d.%d\n",__GNUC__,__GNUC_MINOR__,__GNUC_PATCHLEVEL__);
return 0;
}
[I know this is an old question, but it is worth pointing out new useful solutions as they pop up]
Since python3.6, this capability is now built into the language, coined "f-strings".
See: PEP 498 -- Literal String Interpolation
For example (note the f
prefix):
f'{2**4}'
=> '16'
You can leverage Apache Commons StringUtils.isEmpty(str)
, which checks for empty strings and handles null
gracefully.
Example:
System.out.println(StringUtils.isEmpty("")); // true
System.out.println(StringUtils.isEmpty(null)); // true
Google Guava also provides a similar, probably easier-to-read method: Strings.isNullOrEmpty(str)
.
Example:
System.out.println(Strings.isNullOrEmpty("")); // true
System.out.println(Strings.isNullOrEmpty(null)); // true
you can also introspect all HTTP traffic running over your tunnels using ngrok
, then you can expose using ngrok http --host-header=rewrite 4200
So, there is a simple fix for this. It is admittedly awkward, but it works. xcopy will not prompt to find out if the destination is a directory or file IF the new file(filename) already exists. If you precede your xcopy command with a simple echo to the new filename, it will overwrite the empty file. Example
echo.>newfile.txt
xcopy oldfile.txt newfile.txt /Y
UITableViewCell

Very simple 2 string answer to your question:
$array_1 = array(
'0' => 'zero',
'1' => 'one',
'2' => 'two',
'3' => 'three',
);
At first you insert anything to your third element with array_splice and then assign a value to this element:
array_splice($array_1, 3, 0 , true);
$array_1[3] = array('sample_key' => 'sample_value');
<table border="1" style="width: 100%;">
<colgroup>
<col width="100%" />
<col width="0%" />
</colgroup>
<tr>
<td style="white-space: nowrap; text-overflow:ellipsis; overflow: hidden; max-width:1px;">This cell has more content.This cell has more content.This cell has more content.This cell has more content.This cell has more content.This cell has more content.</td>
<td style="white-space: nowrap;">Less content here.</td>
</tr>
</table>
Try this, it will insert the list item at index 0;
DropDownList1.Items.Insert(0, new ListItem("Add New", ""));
You can't use it from the XML.
You need to extend the widget you are using in the XML and add the logic to set the text using what's mentioned on Konstantin Burov's answer.
Better way is to autowire with a constructor:
private final HttpServletRequest httpServletRequest;
public ClassConstructor(HttpServletRequest httpServletRequest){
this.httpServletRequest = httpServletRequest;
}
Assuming you're using winforms, default panel components does not offer you a way to disable the horizontal scrolling components. A workaround of this is to disable the auto scrolling and add a scrollbar yourself:
ScrollBar vScrollBar1 = new VScrollBar();
vScrollBar1.Dock = DockStyle.Right;
vScrollBar1.Scroll += (sender, e) => { panel1.VerticalScroll.Value = vScrollBar1.Value; };
panel1.Controls.Add(vScrollBar1);

I found a solution, first, delete the ng file with
sudo rm /usr/bin/ng
then install nvm (you need to restart your terminal to use nvm).
then install and use node 6 via nvm
nvm install 6
nvm use 6
finally install angular cli
npm install -g @angular/cli
this worked for me, I wanted to update to v1.0 stable from 1.0.28 beta, but couldn't uninstall the beta version (same situation that you desrcibed). Hope this works
This is implementation dependent, as the C standard does NOT define the signed-ness of char
. Depending on the platform, char may be signed
or unsigned
, so you need to explicitly ask for signed char
or unsigned char
if your implementation depends on it. Just use char
if you intend to represent characters from strings, as this will match what your platform puts in the string.
The difference between signed char
and unsigned char
is as you'd expect. On most platforms, signed char
will be an 8-bit two's complement number ranging from -128
to 127
, and unsigned char
will be an 8-bit unsigned integer (0
to 255
). Note the standard does NOT require that char
types have 8 bits, only that sizeof(char)
return 1
. You can get at the number of bits in a char with CHAR_BIT
in limits.h
. There are few if any platforms today where this will be something other than 8
, though.
There is a nice summary of this issue here.
As others have mentioned since I posted this, you're better off using int8_t
and uint8_t
if you really want to represent small integers.
Make sure to balance the risk that fresh statistics cause undesirable changes to query plans against the risk that stale statistics can themselves cause query plans to change.
Imagine you have a bug database with a table ISSUE and a column CREATE_DATE where the values in the column increase more or less monotonically. Now, assume that there is a histogram on this column that tells Oracle that the values for this column are uniformly distributed between January 1, 2008 and September 17, 2008. This makes it possible for the optimizer to reasonably estimate the number of rows that would be returned if you were looking for all issues created last week (i.e. September 7 - 13). If the application continues to be used and the statistics are never updated, though, this histogram will be less and less accurate. So the optimizer will expect queries for "issues created last week" to be less and less accurate over time and may eventually cause Oracle to change the query plan negatively.
You can use also "void*" (void pointer) to send an address to the function.
typedef struct pstring_t {
char * chars;
int(*length)(void*);
} PString;
int length(void* self) {
return strlen(((PString*)self)->chars);
}
PString initializeString() {
PString str;
str.length = &length;
return str;
}
int main()
{
PString p = initializeString();
p.chars = "Hello";
printf("Length: %i\n", p.length(&p));
return 0;
}
Output:
Length: 5
In a VBA worksheet function UDF you use Application.Caller to get the range of cell(s) that contain the formula that called the UDF.
For those coming across this and looking for performance, it looks like #delete
and #tr
are about the same in speed and 2-4x faster than gsub
.
text = "Here is a string with / some forwa/rd slashes"
tr = Benchmark.measure { 10000.times { text.tr('/', '') } }
# tr.total => 0.01
delete = Benchmark.measure { 10000.times { text.delete('/') } }
# delete.total => 0.01
gsub = Benchmark.measure { 10000.times { text.gsub('/', '') } }
# gsub.total => 0.02 - 0.04

Dynamic web applications also need static files. That’s usually where the CSS and JavaScript files are coming from. Ideally your web server is configured to serve them for you, but during development Flask can do that as well. Just create a folder called

on the application.To generate URLs for static files, use the special
'static'
endpoint name:url_for('static', filename='style.css')
The file has to be stored on the filesystem as

If you have your tomcat started (in linux check with ps -ef | grep java
) and you see it opened the port 8080 or the one you configured in server.xml (check with netstat --tcp -na | grep <port number>
) but you still cannot access it in your browser check the following:
logs/catalina.out
. You should see something like this when the server started completely.

As of 13 April 2020 there is no such functionality unless you are able to use different scopes, but you may use the postinstall script as a workaround. It is always executed, well, after each npm install:
Say you have your .npmrc configured to install @foo-org/foo-pack-private from your private github repo, but the @foo-org/foo-pack-public public package is on npm (under the same scope: foo-org).
Your postinstall might look like this:
"scripts": {
...
"postinstall": "mv .npmrc .npmrcc && npm i @foo-org/foo-pack --dry-run && mv .npmrcc .npmrc".
}
Don't forget to remove @foo-pack/foo-org from the dependencies array to make sure npm install does not try and get it from github and to add the --dry-run flag that makes sure package.json and package-lock.json stay unchanged after npm install.
It depends, but I would say it is better to keep everything in one table for that sake of simplicity.
100,000 rows a day is not really that much of an enormous amount. (Depending on your server hardware). I have personally seen MSSQL handle up to 100M rows in a single table without any problems. As long as your keep your indexes in order it should be all good. The key is to have heaps of memory so that indexes don't have to be swapped out to disk.
On the other hand, it depends on how you are using the data, if you need to make lots of query's, and its unlikely data will be needed that spans multiple days (so you won't need to join the tables) it will be faster to separate out it out into multiple tables. This is often used in applications such as industrial process control where you might be reading the value on say 50,000 instruments every 10 seconds. In this case speed is extremely important, but simplicity is not.

You could also try http://xmltoolbox.appspot.com/ it is an online xml formatter. You just paste your xml into a large text area field and press "format xml" then it pretty prints the xml in the text area so its easy to read or copy.

purls $.params()

jQuerys $.param()

var newUrl = "?" + $.param(params);
Just Remove * from your select clause, and mention all column names explicitly and omit the FIRSTNAME column. After this write CONCAT(FIRSTNAME, ',', LASTNAME) AS FIRSTNAME. The above query will give you the only one FIRSTNAME column.

I know this is an old question. The way I solved it - after failing by increasing the length or even changing to data type text - was creating an XLSX file and importing. It accurately detected the data type instead of setting all columns as varchar(50)
. Turns out nvarchar(255)
for that column would have done it too.
The helpers are there mainly to help you display labels, form inputs, etc for the strongly typed properties of your model. By using the helpers and Visual Studio Intellisense, you can greatly reduce the number of typos that you could make when generating a web page.
With that said, you can continue to create your elements manually for both properties of your view model or items that you want to display that are not part of your view model.

Using .NET 4.5 (or .NET 4.0 by adding the Microsoft.Net.Http package from NuGet) there is an easier way to simulate form requests. Here is an example:
private async Task<System.IO.Stream> Upload(string actionUrl, string paramString, Stream paramFileStream, byte [] paramFileBytes)
{
HttpContent stringContent = new StringContent(paramString);
HttpContent fileStreamContent = new StreamContent(paramFileStream);
HttpContent bytesContent = new ByteArrayContent(paramFileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(stringContent, "param1", "param1");
formData.Add(fileStreamContent, "file1", "file1");
formData.Add(bytesContent, "file2", "file2");
var response = await client.PostAsync(actionUrl, formData);
if (!response.IsSuccessStatusCode)
{
return null;
}
return await response.Content.ReadAsStreamAsync();
}
}
The Java Language Specification, section 15.10, states:
An array creation expression creates an object that is a new array whose elements are of the type specified by the PrimitiveType or ClassOrInterfaceType. It is a compile-time error if the ClassOrInterfaceType does not denote a reifiable type (§4.7).
and
The rules above imply that the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard.
The closest you can do is use an unchecked cast, either from the raw type, as you have done, or from an unbounded wildcard:
HashMap<String, String>[] responseArray = (Map<String, String>[]) new HashMap<?,?>[games.size()];
Your version is clearly better :-)
From the fine manual:
ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;
There's no need to specify the type when you're just changing the nullability.
My answer only supports single line text. Check out gfullam's comment below for the multi-line fork, it looks pretty promising.
I rewrote the code from the first answer a few times, and I think this should be the fastest.
It first finds an "Estimated" text length, and then adds or removes a character until the width is correct.
The logic it uses is shown below:
After an "estimated" text length is found, characters are added or removed until the desired width is reached.
I'm sure it needs some tweaking, but here's the code:
(function ($) {
$.fn.ellipsis = function () {
return this.each(function () {
var el = $(this);
if (el.css("overflow") == "hidden") {
var text = el.html().trim();
var t = $(this.cloneNode(true))
.hide()
.css('position', 'absolute')
.css('overflow', 'visible')
.width('auto')
.height(el.height())
;
el.after(t);
function width() { return t.width() > el.width(); };
if (width()) {
var myElipse = "....";
t.html(text);
var suggestedCharLength = (text.length * el.width() / t.width()) - myElipse.length;
t.html(text.substr(0, suggestedCharLength) + myElipse);
var x = 1;
if (width()) {
while (width()) {
t.html(text.substr(0, suggestedCharLength - x) + myElipse);
x++;
}
}
else {
while (!width()) {
t.html(text.substr(0, suggestedCharLength + x) + myElipse);
x++;
}
x--;
t.html(text.substr(0, suggestedCharLength + x) + myElipse);
}
el.html(t.html());
t.remove();
}
}
});
};
})(jQuery);
I honestly suggest that you use moment.js. Just download moment.min.js
and then use this snippet to get your date in whatever format you want:
<script>
$(document).ready(function() {
// set an element
$("#date").val( moment().format('MMM D, YYYY') );
// set a variable
var today = moment().format('D MMM, YYYY');
});
</script>
Use following chart for date formats:
I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.
I had similar problem. Quick solution is :
ulimit -n 4096
explanation is as follows - each server connection is a file descriptor. In CentOS, Redhat and Fedora, probably others, file user limit is 1024 - no idea why. It can be easily seen when you type: ulimit -n
Note this has no much relation to system max files (/proc/sys/fs/file-max).
In my case it was problem with Redis, so I did:
ulimit -n 4096
redis-server -c xxxx
in your case instead of redis, you need to start your server.

You can take advatange of the css property Box Sizing.
#content {
height: 100%;
-webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
-moz-box-sizing: border-box; /* Firefox, other Gecko */
box-sizing: border-box; /* Opera/IE 8+ */
padding-top: 50px;
margin-top: -50px;
padding-bottom: 50px;
margin-bottom: -50px;
}
See the JsFiddle.
The only property corresponding in WPF to the
Winforms property: TextBox.Multiline = true
is the WPF property: TextBox.AcceptsReturn = true
.
<TextBox AcceptsReturn="True" ...... />
All other settings, such as VerticalAlignement
, WordWrap
etc., only control how the TextBox interacts in the UI but do not affect the Multiline
behaviour.
Use the PackageResourceViewer plugin installed via Package Control (as mentioned by MattDMo). This allows you to override the compressed resources by simply opening it in Sublime Text and saving the file. It automatically saves only the edited resources to %APPDATA%/Roaming/Sublime Text 3/Packages/ or ~/.config/sublime-text-3/Packages/.
Specific to the op, once the plugin is installed, execute the PackageResourceViewer: Open Resource
command. Then select JavaScript
followed by JavaScript.tmLanguage
. This will open an xml file in the editor. You can edit any of the language definitions and save the file. This will write an override copy of the JavaScript.tmLanguage file in the user directory.
The same method can be used to edit the language definition of any language in the system.
Passing an array of items as a collapsed parameter to the WHERE..IN clause will fail since query will take form of WHERE Age IN ("11, 13, 14, 16")
.
But you can pass your parameter as an array serialized to XML or JSON:
nodes()
method:StringBuilder sb = new StringBuilder();
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
sb.Append("<age>" + item.Text + "</age>"); // actually it's xml-ish
sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
SELECT Tab.col.value('.', 'int') as Age from @Ages.nodes('/age') as Tab(col))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = sb.ToString();
OPENXML
method:using System.Xml.Linq;
...
XElement xml = new XElement("Ages");
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
xml.Add(new XElement("age", item.Text);
sqlComm.CommandText = @"DECLARE @idoc int;
EXEC sp_xml_preparedocument @idoc OUTPUT, @Ages;
SELECT * from TableA WHERE Age IN (
SELECT Age from OPENXML(@idoc, '/Ages/age') with (Age int 'text()')
EXEC sp_xml_removedocument @idoc";
sqlComm.Parameters.Add("@Ages", SqlDbType.Xml);
sqlComm.Parameters["@Ages"].Value = xml.ToString();
That's a bit more on the SQL side and you need a proper XML (with root).
OPENJSON
method (SQL Server 2016+):using Newtonsoft.Json;
...
List<string> ages = new List<string>();
foreach (ListItem item in ddlAge.Items)
if (item.Selected)
ages.Add(item.Text);
sqlComm.CommandText = @"SELECT * from TableA WHERE Age IN (
select value from OPENJSON(@Ages))";
sqlComm.Parameters.Add("@Ages", SqlDbType.NVarChar);
sqlComm.Parameters["@Ages"].Value = JsonConvert.SerializeObject(ages);
Note that for the last method you also need to have Compatibility Level at 130+.
I faced the same problem, and none of the options here helped me. Some mail services do not support specified styles. Here is my version, which solved the problem and works everywhere I checked:
<table>
<tr>
<td width="1">Gargantuan Word</td>
</tr>
</table>
OR using CSS:
<table>
<tr>
<td style="width:1px">Gargantuan Word</td>
</tr>
</table>
The line (or lines) between the lines beginning <<<<<<<
and ======
here:
<<<<<<< HEAD:file.txt
Hello world
=======
... is what you already had locally - you can tell because HEAD
points to your current branch or commit. The line (or lines) between the lines beginning =======
and >>>>>>>
:
=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt
... is what was introduced by the other (pulled) commit, in this case 77976da35a11
. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD
. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.
Elasticsearch 1.1+ has the Cardinality Aggregation which will give you a unique count
Note that it is actually an approximation and accuracy may diminish with high-cardinality datasets, but it's generally pretty accurate in my testing.
You can also tune the accuracy with the precision_threshold
parameter. The trade-off, or course, is memory usage.
This graph from the docs shows how a higher precision_threshold
leads to much more accurate results.
I happened to face the same issue, all of a sudden all my imports were missing. I tried deleting all the contents in my .m2 folder. And trying to re-import everything , but still nothing worked. Finally what I did was opened the website for which the IDE was complaining that it couldn't download in my browser. And saw the certificate it was using, and saw in my
$ keytool -v -list PATH_TO_JAVA_KEYSTORE
Path to my keystore was /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
that particular certificate was not there.
So all you have to do is put the certificate into the JAVA JVM keystore again. It can be done using the below command.
$ keytool -import -alias ANY_NAME_YOU_WANT_TO_GIVE -file PATH_TO_YOUR_CERTIFICATE -keystore PATH_OF_JAVA_KEYSTORE
If it asks for password, try the default password 'changeit' If you get permission error when running the above command. In windows open it in administration mode. In mac and unix use sudo.
After you have successfully added the key, You can view it using :
$ keytool -v -list /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
You can view just the SHA-1 using teh command
$ keytool -list /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts
It's actually quite easy to implement as a helper:
Handlebars.registerHelper('eachProperty', function(context, options) {
var ret = "";
for(var prop in context)
{
ret = ret + options.fn({property:prop,value:context[prop]});
}
return ret;
});
Then using it like so:
{{#eachProperty object}}
{{property}}: {{value}}<br/>
{{/eachProperty }}
I was having this problem just now and I was able to solve it in sort of a similar way that @Beatriz Fonseca and @Julie pointed out.
If you go to File
-> Settings
-> Project: YourProjectName
-> Project Structure
, you'll have a directory layout of the project you're currently working in. You'll have to go through your directories and label them as being either the Source
directory for all your Source files, or as a Resource
folder for files that are strictly for importing.
You'll also want to make sure that you place __init__.py
files within your resource directories, or really anywhere that you want to import from, and it'll work perfectly fine.
I hope this answer helps someone, and hopefully JetBrains will fix this annoying bug.
They both are just typecast zero's. Functionally, there's no difference between them. ie.,
#define NULL ((void*)0)
#define nil ((id)0)
There is a difference, but only to yourself and other humans that read the code, the compiler doesn't care.
One more thing nil is an object value while NULL is a generic pointer value.
Run ---> Debug Configuration ---> YourConfiguration ---> Arguments tab
It seems that your problem is more in determining the new file name rather than the rename itself (for which you could use the os.rename method).
It is not clear from your question what the pattern is that you want to be renaming. There is nothing wrong with string manipulation. A regular expression may be what you need here.
There seems no way to have google maps api key free without credit card. To test the functionality of google map you can use it while leaving the api key field "EMPTY". It will show a message saying "For Development Purpose Only". And that way you can test google map functionality without putting billing information for google map api key.
<script src="https://maps.googleapis.com/maps/api/js?key=&callback=initMap" async defer></script>
That's because you should pass a function, not a string:
function funcName() {
alert("test");
}
setInterval(funcName, 10000);
Your code has two problems:
var func = funcName();
calls the function immediately and assigns the return value."func"
is invalid even if you use the bad and deprecated eval-like syntax of setInterval. It would be setInterval("func()", 10000)
to call the function eval-like.ShreevatsaR's answer won't work for all cases, even if you add "if(m<0) m=-m;", if you account for negative dividends/divisors.
For example, -12 mod -10 will be 8, and it should be -2.
The following implementation will work for both positive and negative dividends / divisors and complies with other implementations (namely, Java, Python, Ruby, Scala, Scheme, Javascript and Google's Calculator):
internal static class IntExtensions
{
internal static int Mod(this int a, int n)
{
if (n == 0)
throw new ArgumentOutOfRangeException("n", "(a mod 0) is undefined.");
//puts a in the [-n+1, n-1] range using the remainder operator
int remainder = a%n;
//if the remainder is less than zero, add n to put it in the [0, n-1] range if n is positive
//if the remainder is greater than zero, add n to put it in the [n-1, 0] range if n is negative
if ((n > 0 && remainder < 0) ||
(n < 0 && remainder > 0))
return remainder + n;
return remainder;
}
}
Test suite using xUnit:
[Theory]
[PropertyData("GetTestData")]
public void Mod_ReturnsCorrectModulo(int dividend, int divisor, int expectedMod)
{
Assert.Equal(expectedMod, dividend.Mod(divisor));
}
[Fact]
public void Mod_ThrowsException_IfDivisorIsZero()
{
Assert.Throws<ArgumentOutOfRangeException>(() => 1.Mod(0));
}
public static IEnumerable<object[]> GetTestData
{
get
{
yield return new object[] {1, 1, 0};
yield return new object[] {0, 1, 0};
yield return new object[] {2, 10, 2};
yield return new object[] {12, 10, 2};
yield return new object[] {22, 10, 2};
yield return new object[] {-2, 10, 8};
yield return new object[] {-12, 10, 8};
yield return new object[] {-22, 10, 8};
yield return new object[] { 2, -10, -8 };
yield return new object[] { 12, -10, -8 };
yield return new object[] { 22, -10, -8 };
yield return new object[] { -2, -10, -2 };
yield return new object[] { -12, -10, -2 };
yield return new object[] { -22, -10, -2 };
}
}
To do this you pass a callback as a property down to the child from the parent.
For example:
var Parent = React.createClass({
getInitialState: function() {
return {
value: 'foo'
}
},
changeHandler: function(value) {
this.setState({
value: value
});
},
render: function() {
return (
<div>
<Child value={this.state.value} onChange={this.changeHandler} />
<span>{this.state.value}</span>
</div>
);
}
});
var Child = React.createClass({
propTypes: {
value: React.PropTypes.string,
onChange: React.PropTypes.func
},
getDefaultProps: function() {
return {
value: ''
};
},
changeHandler: function(e) {
if (typeof this.props.onChange === 'function') {
this.props.onChange(e.target.value);
}
},
render: function() {
return (
<input type="text" value={this.props.value} onChange={this.changeHandler} />
);
}
});
In the above example, Parent
calls Child
with a property of value
and onChange
. The Child
in return binds an onChange
handler to a standard <input />
element and passes the value up to the Parent
's callback if it's defined.
As a result the Parent
's changeHandler
method is called with the first argument being the string value from the <input />
field in the Child
. The result is that the Parent
's state can be updated with that value, causing the parent's <span />
element to update with the new value as you type it in the Child
's input field.
Define enum:
public enum Gesture
{
ROCK, PAPER, SCISSORS;
}
Define a method to check enum
content:
private boolean enumContainsValue(String value)
{
for (Gesture gesture : Gesture.values())
{
if (gesture.name().equals(value))
{
return true;
}
}
return false;
}
And use it:
String gestureString = "PAPER";
if (enumContainsValue(gestureString))
{
Gesture gestureId = Gesture.valueOf(gestureString);
switch (gestureId)
{
case ROCK:
Log.i("TAG", "ROCK");
break;
case PAPER:
Log.i("TAG", "PAPER");
break;
case SCISSORS:
Log.i("TAG", "SCISSORS");
break;
}
}
Run this command if your ufw(Uncomplicatd Firewall) is enabled . Add for Example port 8080
$ sudo ufw allow 8080/tcp
And you can check the status by running
$ sudo ufw status

Doesn't look like you are using the correct overload of ActionLink. Try this:-
<%=Html.ActionLink("Modify Villa", "Modify", new {id = "1"})%>
This assumes your view is under the /Views/Villa folder. If not then I suspect you need:-
<%=Html.ActionLink("Modify Villa", "Modify", "Villa", new {id = "1"}, null)%>
top -b -n 1 | mail -s "any subject" [email protected]
It's simple .First you should clear your collection and after clear list like this code :
yourCollection.clear();
setListAdapter(null);
In my case, it happenned for the master branch. Later found that my access to the project was accidentally revoked by the project manager. To cross-check, I visited the review site and couldn't see any commits of the said branch and others for that project.
The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes()
call directly or create a vector for that instead.
This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.
level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses
ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()
or
level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))
ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()
or
directly in the aes()
call without a pre-created vector:
ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()
There is no such functionality in jQuery. Use JSON.stringify
or alternatively any jQuery plugin with similar functionality (e.g jquery-json).
Generic command would be
find /path/to/files -name '<search>*' -exec bash -c 'mv $0 ${0/<search>/<replace>}' {} \;
where <search>
and <replace>
should be replaced with your source and target respectively.
As a more specific example tailored to your problem (should be run from the same folder where your files are), the above command would look like:
find . -name 'gfh*' -exec bash -c 'mv $0 ${0/gfh/jkl}' {} \;
For a "dry run" add echo
before mv
, so that you'd see what commands are generated:
find . -name 'gfh*' -exec bash -c 'echo mv $0 ${0/gfh/jkl}' {} \;
it might be too late but there is neat solution based on Task.WaitAny (c# 5 +) :
public static bool ConnectWithTimeout(this Socket socket, string host, int port, int timeout)
{
bool connected = false;
Task result = socket.ConnectAsync(host, port);
int index = Task.WaitAny(new[] { result }, timeout);
connected = socket.Connected;
if (!connected) {
socket.Close();
}
return connected;
}
Why can't you do it? Because the language doesn't allow you to initializa a base class' members in the derived class' initializer list.
How can you get this done? Like this:
class A
{
public:
A(int a, int b) : a_(a), b_(b) {};
int a_, b_;
};
class B : public A
{
public:
B() : A(0,0)
{
}
};
JPG does not support a transparent background, you can easily convert it to a PNG which does support a transparent background by opening it in near any photo editor and save it as a.PNG
This is not necessarily a VBA task - This specific task is easiest sollowed with Auto filter.
1.Insert Auto filter (In Excel 2010 click on home-> (Editing) Sort & Filter -> Filter)
2. Filter on the 'Websites' column
3. Mark the 'none' and delete them
4. Clear filter
I used this method.
Looper.myLooper().quit();
you can try.
You can just controll it with a boolean, so you only call unbind if bind has been made
public void doBindService()
{
if (!mIsBound)
{
bindService(new Intent(this, DMusic.class), Scon, Context.BIND_AUTO_CREATE);
mIsBound = true;
}
}
public void doUnbindService()
{
if (mIsBound)
{
unbindService(Scon);
mIsBound = false;
}
}
If you only want to unbind it if it has been connected
public ServiceConnection Scon = new ServiceConnection() {
public void onServiceConnected(ComponentName name, IBinder binder)
{
mServ = ((DMusic.ServiceBinder) binder).getService();
mIsBound = true;
}
public void onServiceDisconnected(ComponentName name)
{
mServ = null;
}
};
The accepted answer didn't work for me on Internet Explorer 9. I checked it and the browser detection was not working properly, it detected ff (firefox) when i was at Internet Explorer.
I just did this change:
if ($.browser.msie)
Instead of:
if (br == "ie") {
The resulting code is this one:
function insertAtCaret(areaId,text) {
var txtarea = document.getElementById(areaId);
var scrollPos = txtarea.scrollTop;
var strPos = 0;
var br = ((txtarea.selectionStart || txtarea.selectionStart == '0') ?
"ff" : (document.selection ? "ie" : false ) );
if ($.browser.msie) {
txtarea.focus();
var range = document.selection.createRange();
range.moveStart ('character', -txtarea.value.length);
strPos = range.text.length;
}
else if (br == "ff") strPos = txtarea.selectionStart;
var front = (txtarea.value).substring(0,strPos);
var back = (txtarea.value).substring(strPos,txtarea.value.length);
txtarea.value=front+text+back;
strPos = strPos + text.length;
if (br == "ie") {
txtarea.focus();
var range = document.selection.createRange();
range.moveStart ('character', -txtarea.value.length);
range.moveStart ('character', strPos);
range.moveEnd ('character', 0);
range.select();
}
else if (br == "ff") {
txtarea.selectionStart = strPos;
txtarea.selectionEnd = strPos;
txtarea.focus();
}
txtarea.scrollTop = scrollPos;
}
All fields in JavaScript (and in TypeScript) can have the value null
or undefined
.
You can make the field optional which is different from nullable.
interface Employee1 {
name: string;
salary: number;
}
var a: Employee1 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee1 = { name: 'Bob' }; // Not OK, you must have 'salary'
var c: Employee1 = { name: 'Bob', salary: undefined }; // OK
var d: Employee1 = { name: null, salary: undefined }; // OK
// OK
class SomeEmployeeA implements Employee1 {
public name = 'Bob';
public salary = 40000;
}
// Not OK: Must have 'salary'
class SomeEmployeeB implements Employee1 {
public name: string;
}
Compare with:
interface Employee2 {
name: string;
salary?: number;
}
var a: Employee2 = { name: 'Bob', salary: 40000 }; // OK
var b: Employee2 = { name: 'Bob' }; // OK
var c: Employee2 = { name: 'Bob', salary: undefined }; // OK
var d: Employee2 = { name: null, salary: 'bob' }; // Not OK, salary must be a number
// OK, but doesn't make too much sense
class SomeEmployeeA implements Employee2 {
public name = 'Bob';
}
Run: python -c "import ssl; print(ssl.get_default_verify_paths())"
to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.
The path openssl_capath_env
points to the environment variable: SSL_CERT_DIR
.
If SSL_CERT_DIR
doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.
This is the right way to properly Dispose the DataTable
.
private DataTable CreateSchema_Table()
{
DataTable td = null;
try
{
td = new DataTable();
//use table DataTable here
return td.Copy();
}
catch { }
finally
{
if (td != null)
{
td.Constraints.Clear();
td.Clear();
td.Dispose();
td = null;
}
}
}
In my case, simply giving the user permissions on the database fixed it.
So Right click on the database -> Click Properties -> [left hand menu] Click Permissions -> and scroll down to Backup database -> Tick "Grant"
git add --all
or git add -A
or git add -A .
Stages All
git add .
Stages New & Modified But Without Deleted
git add -u
Stages Modified & Deleted But Without New
git commit -a
Means git add -u
And git commit -m "message"
After writing this command follow these steps:-
git add <list of files>
add specific file
git add *.txt
add all the txt files in current directory
git add docs/*/txt
add all txt files in docs directory
git add docs/
add all files in docs directory
git add "*.txt"
or git add '*.txt'
add all the files in the whole project
Simple:
[1,2,3].map(x => [x, x * 10])
// [[1, 10], [2, 20], [3, 30]]
[1,2,3].flatMap(x => [x, x * 10])
// [1, 10, 2, 20, 3, 30]]
lst_col = 'samples'
r = pd.DataFrame({

for col in df.columns.drop(lst_col)}
).assign(**{lst_col:np.concatenate(df[lst_col].values)})[df.columns]
Result:

PS here you may find a bit more generic solution
UPDATE: some explanations: IMO the easiest way to understand this code is to try to execute it step-by-step:
in the following line we are repeating values in one column N
times where N
- is the length of the corresponding list:
In [10]: np.repeat(df['trial_num'].values, df[lst_col].str.len())
Out[10]: array([1, 1, 1, 2, 2, 2, 3, 3, 3, 1, 1, 1, 2, 2, 2, 3, 3, 3], dtype=int64)
this can be generalized for all columns, containing scalar values:
In [11]: pd.DataFrame({
...: col:np.repeat(df[col].values, df[lst_col].str.len())
...: for col in df.columns.drop(lst_col)}
...: )
Out[11]:
trial_num subject
0 1 1
1 1 1
2 1 1
3 2 1
4 2 1
5 2 1
6 3 1
.. ... ...
11 1 2
12 2 2
13 2 2
14 2 2
15 3 2
16 3 2
17 3 2
[18 rows x 2 columns]
using np.concatenate()
we can flatten all values in the list
column (samples
) and get a 1D vector:
In [12]: np.concatenate(df[lst_col].values)
Out[12]: array([-1.04, -0.58, -1.32, 0.82, -0.59, -0.34, 0.25, 2.09, 0.12, 0.83, -0.88, 0.68, 0.55, -0.56, 0.65, -0.04, 0.36, -0.31])
putting all this together:
