Due to PermGen removal some options were removed (like -XX:MaxPermSize
), but options -Xms
and -Xmx
work in Java 8. It's possible that under Java 8 your application simply needs somewhat more memory. Try to increase -Xmx
value. Alternatively you can try to switch to G1 garbage collector using -XX:+UseG1GC
.
Note that if you use any option which was removed in Java 8, you will see a warning upon application start:
$ java -XX:MaxPermSize=128M -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
I think it would be the following, for example:
[ 2 << 1 ] is => [10 (binary of 2) add 1 zero at the end of the binary string] Hence 10 will be 100 which becomes 4.
Signed left shift uses multiplication... So this could also be calculated as 2 * (2^1) = 4. Another example [2 << 11] = 2 *(2^11) = 4096
[ 4 >> 1 ] is => [100 (binary of 4) remove 1 zero at the end of the binary string] Hence 100 will be 10 which becomes 2.
Signed right shift uses division... So this could also be calculated as 4 / (2^1) = 2 Another example [4096 >> 11] = 4096 / (2^11) = 2
To reset the keys of all arrays in an array:
$arr = array_map('array_values', $arr);
In case you just want to reset first-level array keys, use array_values()
without array_map
.
The problem is with your line
x=np.array ([x0*n])
Here you define x as a single-item array of -200.0. You could do this:
x=np.array ([x0,]*n)
or this:
x=np.zeros((n,)) + x0
Note: your imports are quite confused. You import numpy modules three times in the header, and then later import pylab (that already contains all numpy modules). If you want to go easy, with one single
from pylab import *
line in the top you could use all the modules you need.
It looks to me as though the basic problem is that you have one wait()
call rather than a loop that waits until there are no more children. You also only wait if the last fork()
is successful rather than if at least one fork()
is successful.
You should only use _exit()
if you don't want normal cleanup operations - such as flushing open file streams including stdout
. There are occasions to use _exit()
; this is not one of them. (In this example, you could also, of course, simply have the children return instead of calling exit()
directly because returning from main()
is equivalent to exiting with the returned status. However, most often you would be doing the forking and so on in a function other than main()
, and then exit()
is often appropriate.)
Hacked, simplified version of your code that gives the diagnostics I'd want. Note that your for
loop skipped the first element of the array (mine doesn't).
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>
int main(void)
{
pid_t child_pid, wpid;
int status = 0;
int i;
int a[3] = {1, 2, 1};
printf("parent_pid = %d\n", getpid());
for (i = 0; i < 3; i++)
{
printf("i = %d\n", i);
if ((child_pid = fork()) == 0)
{
printf("In child process (pid = %d)\n", getpid());
if (a[i] < 2)
{
printf("Should be accept\n");
exit(1);
}
else
{
printf("Should be reject\n");
exit(0);
}
/*NOTREACHED*/
}
}
while ((wpid = wait(&status)) > 0)
{
printf("Exit status of %d was %d (%s)\n", (int)wpid, status,
(status > 0) ? "accept" : "reject");
}
return 0;
}
Example output (MacOS X 10.6.3):
parent_pid = 15820
i = 0
i = 1
In child process (pid = 15821)
Should be accept
i = 2
In child process (pid = 15822)
Should be reject
In child process (pid = 15823)
Should be accept
Exit status of 15823 was 256 (accept)
Exit status of 15822 was 0 (reject)
Exit status of 15821 was 256 (accept)
Here is how I made a script that could take either command line inputs or have a text file redirected.
if ($#ARGV < 1) {
@ARGV = ();
@ARGV = <>;
chomp(@ARGV);
}
This will reassign the contents of the file to @ARGV, from there you just process @ARGV as if someone was including command line options.
WARNING
If no file is redirected, the program will sit their idle because it is waiting for input from STDIN.
I have not figured out a way to detect if a file is being redirected in yet to eliminate the STDIN issue.
I am trying to explain by putting problem statement and solution to it. I hope it will help

Yes, it is asking for the application/executable that is capable of creating Javadoc. There is a javadoc
executable inside the jdk's bin folder.
if you have textviews, buttons or stg clickable or selectable in your row view only
android:descendantFocusability="blocksDescendants"
is not enough. You have to set
android:textIsSelectable="false"
to your textviews and
android:focusable="false"
to your buttons and other focusable items.
I had the same error. My issue was using the wrong parameter name when binding.
Notice :tokenHash in the query, but :token_hash when binding. Fixing one or the other resolves the error in this instance.
// Prepare DB connection
$sql = 'INSERT INTO rememberedlogins (token_hash,user_id,expires_at)
VALUES (:tokenHash,:user_id,:expires_at)';
$db = static::getDB();
$stmt = $db->prepare($sql);
// Bind values
$stmt->bindValue(':token_hash',$hashed_token,PDO::PARAM_STR);
Here is an extended version of the answer @Ian Atkin' gave. I found it worked extremely well. For larger images that is :). You can actually make smaller images larger if you're not careful. Changes: - Supports jpg,jpeg,png,gif,bmp files - Preserves transparency for .png and .gif - Double checks if the the size of the original isnt already smaller - Overrides the image given directly (Its what I needed)
So here it is. The default values of the function are the "golden rule"

return true;
}
$r = $width / $height;
if ($crop) {
if ($width > $height) {
$width = ceil($width - ($width * abs($r - $w / $h)));
} else {
$height = ceil($height - ($height * abs($r - $w / $h)));
}
$newwidth = $w;
$newheight = $h;

$newwidth = $h * $r;
$newheight = $h;

$newheight = $w / $r;

YouTube is serving thumbnails from 2 servers. You just need to replace <YouTube_Video_ID_HERE> with your own YouTube video id. These days webP is best format for fast loading of images due to small image size.

There are two common approaches. First, you can pass System.Type
object GetColumnValue(string columnName, Type type)
{
// Here, you can check specific types, as needed:
if (type == typeof(int)) { // ...
This would be called like: int val = (int)GetColumnValue(columnName, typeof(int));
The other option would be to use generics:
T GetColumnValue<T>(string columnName)
{
// If you need the type, you can use typeof(T)...
This has the advantage of avoiding the boxing and providing some type safety, and would be called like: int val = GetColumnValue<int>(columnName);
You could use the DateTime class as well:
$timestamp = mktime(15, 30, 00, 3, 28, 2015);
$d = new DateTime();
$d->setTimestamp($timestamp);
Add a Period of 1 Day:
$d->add(new DateInterval('P1D'));
echo $d->format('c');
See DateInterval for more details.
import java.util.Scanner;
public class Shift {
public static void main(String[] args) {
Scanner input = new Scanner (System.in);
int array[] = new int [5];
int array1[] = new int [5];
int i, temp;
for (i=0; i<5; i++) {
System.out.printf("Enter array[%d]: \n", i);
array[i] = input.nextInt(); //Taking input in the array
}
System.out.println("\nEntered datas are: \n");
for (i=0; i<5; i++) {
System.out.printf("array[%d] = %d\n", i, array[i]); //This will show the data you entered (Not the shifting one)
}
temp = array[4]; //We declared the variable "temp" and put the last number of the array there...
System.out.println("\nAfter Shifting: \n");
for(i=3; i>=0; i--) {
array1[i+1] = array[i]; //New array is "array1" & Old array is "array". When array[4] then the value of array[3] will be assigned in it and this goes on..
array1[0] = temp; //Finally the value of last array which was assigned in temp goes to the first of the new array
}
for (i=0; i<5; i++) {
System.out.printf("array[%d] = %d\n", i, array1[i]);
}
input.close();
}
}
This can also be done at the Project Level: In the Package Explorer, right-click on the project > Properties > Java Editor > Save Actions
This might be preferable when working as a team so that everyone's code is saved with the same format settings.
However, There is one more way to check the object in jQuery.
jQuery.type(a); //this returns type of variable.

In my case, the error occurred when I made python manage.py makemigrations
on Django 2.0.6
.
The solution was to run python manage.py runserver
and see the actual error (which was just a missing environment variable).
Check out the request module.
It's more full featured than node's built-in http client.
var request = require('request');
var propertiesObject = { field1:'test1', field2:'test2' };
request({url:url, qs:propertiesObject}, function(err, response, body) {
if(err) { console.log(err); return; }
console.log("Get response: " + response.statusCode);
});
I was looking for a solution to this and used the indirect one found on this page initially, but I found it quite long and clunky for what I was trying to do. After a bit of research, I found a more elegant solution (to my problem) using R1C1 notation - I think you can't mix different notation styles without using VBA though.
Depending on what you're trying to do with the self referenced cell, something like this example should get a cell to reference itself where the cell is F13:
Range("F13").FormulaR1C1 = "RC"
And you can then reference cells in relative positions to that cell such as - where your cell is F13 and you need to reference G12 from it.
Range("F13").FormulaR1C1 = "R[-1]C[1]"
You're essentially telling Excel to find F13 and then move down 1 row and up one column from that.
How this fit into my project was to apply a vlookup across a range where the lookup value was relative to each cell in the range without having to specify each lookup cell separately:
Sub Code()
Dim Range1 As Range
Set Range1 = Range("B18:B23")
Range1.Locked = False
Range1.FormulaR1C1 = "=IFERROR(VLOOKUP(RC[-1],DATABYCODE,2,FALSE),"""")"
Range1.Locked = True
End Sub
My lookup value is the cell to the left of each cell (column -1) in my DIM'd range and DATABYCODE is the named range I'm looking up against.
Hope that makes a little sense? Thought it was worth throwing into the mix as another way to approach the problem.
This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):
It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.
Here are the commands again for easier copy-pasting:
openssl rsa -in $FF -out $TF
openssl rsa -aes256 -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF
and
openssl rsa -check -in $FF
openssl rsa -text -in $FF
Try this add "icon" with your stylesheet Maybe it solve your error "favicon.ico:1 not found "
OR First Try to understand about favicon.enter image description here SET your favicon icon file in your folder. You can generate your favicon using "https://favicon.io/favicon-generator/".
Create 2 methods which handle the cases. You can instruct the @RequestMapping
annotation to take into account certain parameters whilst mapping the request. That way you can nicely split this into 2 methods.
@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET,
produces="text/xml", params={"logout"})
public String handleLogout(@PathVariable("id") String id,
@RequestParam("logout") String logout) { ... }
@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET,
produces="text/xml", params={"name", "password"})
public String handleLogin(@PathVariable("id") String id, @RequestParam("name")
String username, @RequestParam("password") String password,
@ModelAttribute("submitModel") SubmitModel model, BindingResult errors)
throws LoginException {...}

Read the tutorial on Java Web applications.
Basically Web applications are a part of the Java EE standard. A lot of people only use the Web (servlets) part with additional frameworks thrown in, most notably Spring but also Struts, Seam and others.
All you need is an IDE like IntelliJ, Eclipse or Netbeans, the JDK, the Java EE download and a servlet container like Tomcat (or a full-blown application server like Glassfish or JBoss).
Here is a Tomcat tutorial.
Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:
ViewModel
, and include the Model as member in the ViewModel
, then you effectively sent your model to the View => this is BADSo how can you create a better coupling?
I would use a tool like AutoMapper
or ValueInjecter to map between ViewModel
and Model.
AutoMapper
does seem to have the better syntax and feel to it, but the current version lacks a
very severe topic: It is not able to perform the mapping from ViewModel
to Model (under certain circumstances like flattening, etc., but this is off topic)
So at present I prefer to use ValueInjecter
.
So you create a ViewModel
with the fields you need in the view.
You add the SelectList items you need as lookups.
And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist:
You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList
from the view to the controller.
// StaffTypes is an IEnumerable<StaffType> from dbContext
// viewModel is the viewModel initialized to copy content of Model Employee
// viewModel.StaffTypes is of type SelectList
viewModel.StaffTypes =
new SelectList(
StaffTypes.OrderBy( item => item.Name )
"StaffTypeID",
"Type",
viewModel.StaffTypeID
);
In the view you just have to call
@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )
Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel
. You then check for validation.
If the validation fails, you have to remember to re-populate the viewModel.StaffTypes
SelectList, because this item will be null on entering the post function.
So I tend to have those population things separated into a function.
You just call back return new View(viewModel)
if anything is wrong.
Validation errors found by MVC3 will automatically be shown in the view.
If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState
to get info on that.
If the viewModel
is valid you have to perform the next step:
If it is a create of a new item, you have to populate a model from the viewModel
(best suited is ValueInjecter
). Then you can add it to the EF collection of that type and commit changes.
If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel
back to the model (again using ValueInjecter
gets you do that very quick).
After that you can SaveChanges
and are done.
Feel free to ask if anything is unclear.
Look at SignalR Tests for the feature.
Test "SendToUser" takes automatically the user identity passed by using a regular owin authentication library.
The scenario is you have a user who has connected from multiple devices/browsers and you want to push a message to all his active connections.
There are several problems with your code:
WordList
is not defined anywhere. You should define it before you use it.#include <string>
before you can use the string class and iostream before you use cout
or endl
.string
, cout
and endl
live in the std
namespace, so you can not access them without prefixing them with std::
unless you use the using
directive to bring them into scope first.Decompyle++ (pycdc) was the only one that worked for me: https://github.com/zrax/pycdc
was suggested in Decompile Python 2.7 .pyc
One line:

File sutest
#!/bin/bash
echo "uid is ${UID}"
echo "user is ${USER}"
echo "username is ${USERNAME}"
run it: `./sutest' gives me
uid is 500
user is stephenp
username is stephenp
but using sudo: sudo ./sutest
gives
uid is 0
user is root
username is stephenp
So you retain the original user name in $USERNAME when running as sudo. This leads to a solution similar to what others posted:
#!/bin/bash
sudo -u ${USERNAME} normal_command_1
root_command_1
root_command_2
sudo -u ${USERNAME} normal_command_2
# etc.
Just sudo to invoke your script in the first place, it will prompt for the password once.
I originally wrote this answer on Linux, which does have some differences with OS X
OS X (I'm testing this on Mountain Lion 10.8.3) has an environment variable SUDO_USER
when you're running sudo, which can be used in place of USERNAME
above, or to be more cross-platform the script could check to see if SUDO_USER is set and use it if so, or use USERNAME if that's set.
Changing the original script for OS X, it becomes...
#!/bin/bash
sudo -u ${SUDO_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${SUDO_USER} normal_command_2
# etc.
A first stab at making it cross-platform could be...
#!/bin/bash
#
# set "THE_USER" to SUDO_USER if that's set,
# else set it to USERNAME if THAT is set,
# else set it to the string "unknown"
# should probably then test to see if it's "unknown"
#
THE_USER=${SUDO_USER:-${USERNAME:-unknown}}
sudo -u ${THE_USER} normal_command_1
root_command_1
root_command_2
sudo -u ${THE_USER} normal_command_2
# etc.
Here are the steps:
It seems you are checking the .project file into the source repository. I would suggest not checking in the .project file so users can have their own version of the file. Also, if you use the subclipse plugin it allows you to check out and configure a source folder as a java project. This process creates the correct .project for you(with the java nature),
Speaking as a mere mortal, I would stick with $str[0]
. As far as I'm concerned, it's quicker to grasp the meaning of $str[0]
at a glance than substr($str, 0, 1)
. This probably boils down to a matter of preference.
As far as performance goes, well, profile profile profile. :) Or you could peer into the PHP source code...
As you are using SQL Server 2008, go with Martin's answer.
If you find yourself needing to do it in SQL Server 2005 where you don't have access to the Date
column type, I'd use:
SELECT DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)
Use String.PadLeft like this:
var result = input.ToString().PadLeft(length, '0');
Another answer based on extensions (boy do I miss this in Java):
extension NSData {
func toUtf8() -> String? {
return String(data: self, encoding: NSUTF8StringEncoding)
}
}
Then you can use it:
let data : NSData = getDataFromEpicServer()
let string : String? = data.toUtf8()
Note that the string is optional, the initial NSData
may be unconvertible to Utf8.
To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.
COPY ./files/. /files/
Another method utilizing the dplyr package:
library(dplyr)
df <- mtcars %>%
filter(mpg > 25)
Without the chain (%>%) operator:
library(dplyr)
df <- filter(mtcars, mpg > 25)
If you are clearing the cluster so that you can start again, then, in addition to what @rib47 said, I also do the following to ensure my systems are in a state ready for kubeadm init
again:
kubeadm reset -f
rm -rf /etc/cni /etc/kubernetes /var/lib/dockershim /var/lib/etcd /var/lib/kubelet /var/run/kubernetes ~/.kube/*
iptables -F && iptables -X
iptables -t nat -F && iptables -t nat -X
iptables -t raw -F && iptables -t raw -X
iptables -t mangle -F && iptables -t mangle -X
systemctl restart docker
You then need to re-install docker.io
, kubeadm
, kubectl
, and kubelet
to make sure they are at the latest versions for your distribution before you re-initialize the cluster.
EDIT: Discovered that calico adds firewall rules to the raw
table so that needs clearing out as well.
As (Bourne) shell variables cannot contain dots you can replace them by underscores. Read every line, translate . in the key to _ and evaluate.
#/bin/sh
file="./app.properties"
if [ -f "$file" ]
then
echo "$file found."
while IFS='=' read -r key value
do
key=$(echo $key | tr '.' '_')
eval ${key}=\${value}
done < "$file"
echo "User Id = " ${db_uat_user}
echo "user password = " ${db_uat_passwd}
else
echo "$file not found."
fi
Note that the above only translates . to _, if you have a more complex format you may want to use additional translations. I recently had to parse a full Ant properties file with lots of nasty characters, and there I had to use:
key=$(echo $key | tr .-/ _ | tr -cd 'A-Za-z0-9_')
For a unique column, use this:
INSERT OR REPLACE INTO table () values();
For more information, see: sqlite.org/lang_insert
This is an older question with a proper answer (please use parameterized queries) which I'd like to extend with some timezone discussion. For my current project I was interested in how do the datetime
columns handle timezones and this question is the one I found.
Turns out, they do not, at all.
datetime
column stores the given DateTime
as is, without any conversion. It does not matter if the given datetime is UTC or local.
You can see for yourself:
using (var connection = new SqlConnection(connectionString))
{
connection.Open();
using (var command = connection.CreateCommand())
{
command.CommandText = "SELECT * FROM (VALUES (@a, @b, @c)) example(a, b, c);";
var local = DateTime.Now;
var utc = local.ToUniversalTime();
command.Parameters.AddWithValue("@a", utc);
command.Parameters.AddWithValue("@b", local);
command.Parameters.AddWithValue("@c", utc.ToLocalTime());
using (var reader = command.ExecuteReader())
{
reader.Read();
var localRendered = local.ToString("o");
Console.WriteLine($"a = {utc.ToString("o").PadRight(localRendered.Length, ' ')} read = {reader.GetDateTime(0):o}, {reader.GetDateTime(0).Kind}");
Console.WriteLine($"b = {local:o} read = {reader.GetDateTime(1):o}, {reader.GetDateTime(1).Kind}");
Console.WriteLine($"{"".PadRight(localRendered.Length + 4, ' ')} read = {reader.GetDateTime(2):o}, {reader.GetDateTime(2).Kind}");
}
}
}
What this will print will of course depend on your time zone but most importantly the read values will all have Kind = Unspecified
. The first and second output line will be different by your timezone offset. Second and third will be the same. Using the "o" format string (roundtrip) will not show any timezone specifiers for the read values.
Example output from GMT+02:00:
a = 2018-11-20T10:17:56.8710881Z read = 2018-11-20T10:17:56.8700000, Unspecified
b = 2018-11-20T12:17:56.8710881+02:00 read = 2018-11-20T12:17:56.8700000, Unspecified
read = 2018-11-20T12:17:56.8700000, Unspecified
Also note of how the data gets truncated (or rounded) to what seems like 10ms.

An alternative stacking arrangement which works and is perhaps a bit more intuitive is the following:
struct ContentView: View {
var body: some View {
HStack() {
VStack(alignment: .leading) {
Text("Hello World")
.font(.title)
Text("Another")
.font(.body)
Spacer()
}
Spacer()
}.background(Color.red)
}
}
The content can also easily be re-positioned by removing the Spacer()
's if necessary.
The following are tried, tested and proven methods to check if a row exists.
(Some of which I use myself, or have used in the past).
Edit: I made an previous error in my syntax where I used mysqli_query()
twice. Please consult the revision(s).
I.e.:
if (!mysqli_query($con,$query))
which should have simply read as if (!$query)
.
Side note: Both '".$var."'
and '$var'
do the same thing. You can use either one, both are valid syntax.
Here are the two edited queries:
$query = mysqli_query($con, "SELECT * FROM emails WHERE email='".$email."'");
if (!$query)
{
die('Error: ' . mysqli_error($con));
}
if(mysqli_num_rows($query) > 0){
echo "email already exists";
}else{
// do something
}
and in your case:
$query = mysqli_query($dbl, "SELECT * FROM `tblUser` WHERE email='".$email."'");
if (!$query)
{
die('Error: ' . mysqli_error($dbl));
}
if(mysqli_num_rows($query) > 0){
echo "email already exists";
}else{
// do something
}
You can also use mysqli_
with a prepared statement method:
$query = "SELECT `email` FROM `tblUser` WHERE email=?";
if ($stmt = $dbl->prepare($query)){
$stmt->bind_param("s", $email);
if($stmt->execute()){
$stmt->store_result();
$email_check= "";
$stmt->bind_result($email_check);
$stmt->fetch();
if ($stmt->num_rows == 1){
echo "That Email already exists.";
exit;
}
}
}
Or a PDO method with a prepared statement:
<?php
$email = $_POST['email'];
$mysql_hostname = 'xxx';
$mysql_username = 'xxx';
$mysql_password = 'xxx';
$mysql_dbname = 'xxx';
try {
$conn= new PDO("mysql:host=$mysql_hostname;dbname=$mysql_dbname", $mysql_username, $mysql_password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
exit( $e->getMessage() );
}
// assuming a named submit button
if(isset($_POST['submit']))
{
try {
$stmt = $conn->prepare('SELECT `email` FROM `tblUser` WHERE email = ?');
$stmt->bindParam(1, $_POST['email']);
$stmt->execute();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
}
}
catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
if($stmt->rowCount() > 0){
echo "The record exists!";
} else {
echo "The record is non-existant.";
}
}
?>
N.B.:
When dealing with forms and POST arrays as used/outlined above, make sure that the POST arrays contain values, that a POST method is used for the form and matching named attributes for the inputs.
Note: <input type = "text" name = "var">
- $_POST['var']
match. $_POST['Var']
no match.

Error: cannot allocate vector of size 5.4 Gb
The solution is really simple and consist in increasing the storage capacity of R, here the code line:
##To know the current storage capacity
> memory.limit()
[1] 8103
## To increase the storage capacity
> memory.limit(size=56000)
[1] 56000
## I did this to increase my storage capacity to 7GB
Hopefully, this will help you to solve the problem Cheers
Apart from Thread.join()
suggested by others, java 5 introduced the executor framework. There you don't work with Thread
objects. Instead, you submit your Callable
or Runnable
objects to an executor. There's a special executor that is meant to execute multiple tasks and return their results out of order. That's the ExecutorCompletionService
:
ExecutorCompletionService executor;
for (..) {
executor.submit(Executors.callable(yourRunnable));
}
Then you can repeatedly call take()
until there are no more Future<?>
objects to return, which means all of them are completed.
Another thing that may be relevant, depending on your scenario is CyclicBarrier
.
A synchronization aid that allows a set of threads to all wait for each other to reach a common barrier point. CyclicBarriers are useful in programs involving a fixed sized party of threads that must occasionally wait for each other. The barrier is called cyclic because it can be re-used after the waiting threads are released.
To make print view look like tablet or desktop include bootstrap as .less, not as .css and then you can overwrite bootstrap responsive classes in the end of bootstrap_variables file for example like this:
@container-sm: 1200px;
@container-md: 1200px;
@container-lg: 1200px;
@screen-sm: 0;
Don't worry about putting this variables in the end of the file. LESS supports lazy loading of variables so they will be applied.
Based on @lijat, here is a simplified implementation. In my spring-based application I simply load this as a bean.
public static void configureLog4jFromSystemProperties()
{
final String LOGGER_PREFIX = "log4j.logger.";
for(String propertyName : System.getProperties().stringPropertyNames())
{
if (propertyName.startsWith(LOGGER_PREFIX)) {
String loggerName = propertyName.substring(LOGGER_PREFIX.length());
String levelName = System.getProperty(propertyName, "");
Level level = Level.toLevel(levelName); // defaults to DEBUG
if (!"".equals(levelName) && !levelName.toUpperCase().equals(level.toString())) {
logger.error("Skipping unrecognized log4j log level " + levelName + ": -D" + propertyName + "=" + levelName);
continue;
}
logger.info("Setting " + loggerName + " => " + level.toString());
Logger.getLogger(loggerName).setLevel(level);
}
}
}
In gcc, you can label the parameter with the unused
attribute.
This attribute, attached to a variable, means that the variable is meant to be possibly unused. GCC will not produce a warning for this variable.
In practice this is accomplished by putting __attribute__ ((unused))
just before the parameter. For example:
void foo(workerid_t workerId) { }
becomes
void foo(__attribute__((unused)) workerid_t workerId) { }
.sr-only
is a class name specifically used for screen readers. You can use any class name, but .sr-only
is pretty commonly used. If you don't care about developing with compliance in mind, then it can be removed. It will not affect UI in any way if removed because the CSS for this class is not visible to desktop and mobile device browsers.
There seems to be some information missing here about the use of .sr-only
to explain its purpose and being for screen readers. First and foremost, it is very important to always keep impaired users in mind. Impairment is the purpose of 508 compliance: https://www.section508.gov/, and it is great that bootstrap takes this into consideration. However, the use of .sr-only
is not all that needs to be taken into consideration for 508 compliance. You have the use of color, size of fonts, accessibility via navigation, descriptors, use of aria and so much more.
But as for .sr-only
- what does the CSS actually do? There are several slightly different variants of the CSS used for .sr-only
. One of the few I use is below:
.sr-only {
position: absolute;
margin: -1px 0 0 -1px;
padding: 0;
display: block;
width: 1px;
height: 1px;
font-size: 1px;
line-height: 1px;
overflow: hidden;
clip: rect(0,0,0,0);
border: 0;
outline: 0;
}
The above CSS hides content in desktop and mobile browsers wrapped with this class, but is seen by a screen reader like JAWS: http://www.freedomscientific.com/Products/Blindness/JAWS. Example markup is as follows:
<a href="#" target="_blank">
Click to Open Site
<span class="sr-only">This is an external link</span>
</a>
Additionally, if a DOM element has a width and height of 0, the element is not seen by the DOM. This is why the above CSS uses width: 1px; height: 1px;
. By using display: none
and setting your CSS to height: 0
and width: 0
, the element is not seen by the DOM and is thus problematic. The above CSS using width: 1px; height: 1px;
is not all you do to make the content invisible to desktop and mobile browsers (without overflow: hidden
, your content would still show on the screen), and visible to screen readers. Hiding the content from desktop and mobile browsers is done by adding an offset from width: 1px
and height: 1px
previously mentioned by using:
position: absolute;
margin: -1px 0 0 -1px;
overflow: hidden;
Lastly, to have a very good idea of what a screen reader sees and relays to its impaired user, turn off page styling for your browser. For Firefox, you can do this by going to:
View > Page Style > No Style
I hope the information I provided here is of further use to someone in addition to the other responses.
List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");
//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));
//Output : C
items.forEach(item->{
System.out.println(item);
System.out.println(item.toLowerCase());
}
});
Another simple solution for processing unknown or multiple arguments can be:
class ExampleClass(object):
def __init__(self, x, y, **kwargs):
self.x = x
self.y = y
self.attributes = kwargs
def SomeFunction(self):
if 'something' in self.attributes:
dosomething()
declare @sql1 nvarchar(max)
SELECT @sql1 =
STUFF(
(
select ' drop table dbo.[' + name + ']'
FROM sys.sysobjects AS sobjects
WHERE (xtype = 'U') AND (name LIKE 'GROUP_BASE_NEW_WORK_%')
for xml path('')
),
1, 1, '')
execute sp_executesql @sql1
One important missing bit is, what is the correct way to resolve this issue?
As Greg explained, the root problem here is that a base class constructor would invoke the virtual member before the derived class has been constructed.
The following code, taken from MSDN's constructor design guidelines, demonstrates this issue.
public class BadBaseClass
{
protected string state;
public BadBaseClass()
{
this.state = "BadBaseClass";
this.DisplayState();
}
public virtual void DisplayState()
{
}
}
public class DerivedFromBad : BadBaseClass
{
public DerivedFromBad()
{
this.state = "DerivedFromBad";
}
public override void DisplayState()
{
Console.WriteLine(this.state);
}
}
When a new instance of DerivedFromBad
is created, the base class constructor calls to DisplayState
and shows BadBaseClass
because the field has not yet been update by the derived constructor.
public class Tester
{
public static void Main()
{
var bad = new DerivedFromBad();
}
}
An improved implementation removes the virtual method from the base class constructor, and uses an Initialize
method. Creating a new instance of DerivedFromBetter
displays the expected "DerivedFromBetter"
public class BetterBaseClass
{
protected string state;
public BetterBaseClass()
{
this.state = "BetterBaseClass";
this.Initialize();
}
public void Initialize()
{
this.DisplayState();
}
public virtual void DisplayState()
{
}
}
public class DerivedFromBetter : BetterBaseClass
{
public DerivedFromBetter()
{
this.state = "DerivedFromBetter";
}
public override void DisplayState()
{
Console.WriteLine(this.state);
}
}
An empty string will raise an error if you access [1:]. Therefore I would use:
def my_uppercase(title):
if not title:
return ''
return title[0].upper() + title[1:]
to uppercase the first letter only.
You can check your respone content, just console.log it and you will see whitch property have a status code. If you do not understand jsons, please refer to the video: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts
It explains very basic knowledge that let you feel more comfortable with javascript.
You can do it with shorter version of ajax request, please see code above:
$.get("example.url.com", function(data) {
console.log(data);
}).done(function() {
// TO DO ON DONE
}).fail(function(data, textStatus, xhr) {
//This shows status code eg. 403
console.log("error", data.status);
//This shows status message eg. Forbidden
console.log("STATUS: "+xhr);
}).always(function() {
//TO-DO after fail/done request.
console.log("ended");
});
Example console output:
error 403
STATUS: Forbidden
ended
If you want a quick demo and more details about how you move elements, try this link:
http://html-tuts.com/move-div-in-another-div-with-jquery
Here is a short example:
To move ABOVE an element:
$('.whatToMove').insertBefore('.whereToMove');
To move AFTER an element:
$('.whatToMove').insertAfter('.whereToMove');
To move inside an element, ABOVE ALL elements inside that container:
$('.whatToMove').prependTo('.whereToMove');
To move inside an element, AFTER ALL elements inside that container:
$('.whatToMove').appendTo('.whereToMove');

I can recommend jOOQ. It provides a lot of great features, also a intuitive DSL for SQL and a extremly customable reverse-engineering approach.
jOOQ effectively combines complex SQL, typesafety, source code generation, active records, stored procedures, advanced data types, and Java in a fluent, intuitive DSL.
A quick update to Michael's excellent answer above.
For Rails 4.0+ you need to put your sort in a block like this:
class Book < ActiveRecord::Base
default_scope { order('created_at DESC') }
end
Notice that the order statement is placed in a block denoted by the curly braces.
They changed it because it was too easy to pass in something dynamic (like the current time). This removes the problem because the block is evaluated at runtime. If you don't use a block you'll get this error:
Support for calling #default_scope without a block is removed. For example instead of
default_scope where(color: 'red')
, please usedefault_scope { where(color: 'red') }
. (Alternatively you can just redefine self.default_scope.)
As @Dan mentions in his comment below, you can do a more rubyish syntax like this:
class Book < ActiveRecord::Base
default_scope { order(created_at: :desc) }
end
or with multiple columns:
class Book < ActiveRecord::Base
default_scope { order({begin_date: :desc}, :name) }
end
Thanks @Dan!
Well, You can do it with mustache expression ({{Date.now() | date:'dd.MM.yyyy HH:mm:ss'}}
). You just need to assign the Date object to scope where You want to evaluate this expression.
Here's jsfiddle example: jsfiddle
But don't expect it to update value automatically. This value is not watched by angular so You have to trigger digest every time You want to get it updated (by $interval for example)...which is waste of resources (and also not "recommended" in docs). Of course You can get to use of combination with directives/controllers to mess around with child scope only (it's always smaller than for example rootScope and digest will be quicker).
I don't believe there's anything within .NET to allow copying a section of a file without buffering it in memory. However, it strikes me that this is inefficient anyway, as it needs to open the input file and seek many times. If you're just splitting up the file, why not open the input file once, and then just write something like:
public static void CopySection(Stream input, string targetFile, int length)
{
byte[] buffer = new byte[8192];
using (Stream output = File.OpenWrite(targetFile))
{
int bytesRead = 1;
// This will finish silently if we couldn't read "length" bytes.
// An alternative would be to throw an exception
while (length > 0 && bytesRead > 0)
{
bytesRead = input.Read(buffer, 0, Math.Min(length, buffer.Length));
output.Write(buffer, 0, bytesRead);
length -= bytesRead;
}
}
}
This has a minor inefficiency in creating a buffer on each invocation - you might want to create the buffer once and pass that into the method as well:
public static void CopySection(Stream input, string targetFile,
int length, byte[] buffer)
{
using (Stream output = File.OpenWrite(targetFile))
{
int bytesRead = 1;
// This will finish silently if we couldn't read "length" bytes.
// An alternative would be to throw an exception
while (length > 0 && bytesRead > 0)
{
bytesRead = input.Read(buffer, 0, Math.Min(length, buffer.Length));
output.Write(buffer, 0, bytesRead);
length -= bytesRead;
}
}
}
Note that this also closes the output stream (due to the using statement) which your original code didn't.
The important point is that this will use the operating system file buffering more efficiently, because you reuse the same input stream, instead of reopening the file at the beginning and then seeking.
I think it'll be significantly faster, but obviously you'll need to try it to see...
This assumes contiguous chunks, of course. If you need to skip bits of the file, you can do that from outside the method. Also, if you're writing very small files, you may want to optimise for that situation too - the easiest way to do that would probably be to introduce a BufferedStream
wrapping the input stream.
Use one of keyup / keydown / beforeinput events instead.
based on this reference, keypress is deprecated and no longer recommended.
The keypress event is fired when a key that produces a character value is pressed down. Examples of keys that produce a character value are alphabetic, numeric, and punctuation keys. Examples of keys that don't produce a character value are modifier keys such as Alt, Shift, Ctrl, or Meta.
if you use "beforeinput" be careful about it's Browser compatibility. the difference between "beforeinput" and the other two is that "beforeinput" is fired when input value is about to changed, so with characters that can't change the input value, it is not fired (e.g shift, ctr ,alt).
I had the same problem and by using keyup it was solved.
I think you can do this by calculating the height and width you want with javascript (via document.body.clientWidth etc.) and then injecting the iframe into your HTML like this:
var element = document.getElementById("myid"); element.innerHTML += "<iframe src='http://www.google.com' height='200' width='" + document.body.clientWidth * 0.8 + "'/>";
I didn't test this in IE6 but it seems to work with the good ones :)
Replace your implementation
with classpath
. That should work.
Others have answered in terms of how to handle the specific escaping in this case.
A broader answer is not to try to do it yourself. Use an XML API - there are plenty available for just about every modern programming platform in existence.
XML APIs will handle things like this for you automatically, making it a lot harder to go wrong. Unless you're writing an XML API yourself, you should rarely need to worry about the details like this.

You could start the container setting a container name:
docker run -d --name <container-name> <image-name>
The same image could be used to spin up multiple containers, so this is a good way to start a container. Then you could use this container-name to stop, attach... the container:
docker exec -it <container-name> bash
docker stop <container-name>
docker rm <container-name>
In System.Web.Mvc.Html ( in System.Web.Mvc.dll ) the begin form is defined like:- Details
BeginForm ( this HtmlHelper htmlHelper, string actionName, string
controllerName, object routeValues, FormMethod method, object htmlAttributes)
Means you should use like this :
Html.BeginForm( string actionName, string controllerName,object routeValues, FormMethod method, object htmlAttributes)
So, it worked in MVC 4
@using (Html.BeginForm(null, null, new { @id = string.Empty }, FormMethod.Post,
new { @id = "signupform" }))
{
<input id="TRAINER_LIST" name="TRAINER_LIST" type="hidden" value="">
<input type="submit" value="Create" id="btnSubmit" />
}

This is how the JDK does it (adapted from OpenJDK 8, String.java/regionMatches):
static boolean charactersEqualIgnoringCase(char c1, char c2) {
if (c1 == c2) return true;
// If characters don't match but case may be ignored,
// try converting both characters to uppercase.
char u1 = Character.toUpperCase(c1);
char u2 = Character.toUpperCase(c2);
if (u1 == u2) return true;
// Unfortunately, conversion to uppercase does not work properly
// for the Georgian alphabet, which has strange rules about case
// conversion. So we need to make one last check before
// exiting.
return Character.toLowerCase(u1) == Character.toLowerCase(u2);
}
I suppose that works for Turkish too.
You can use querySelectorAll to get all span elements and then use new ES2015 (ES6) spread operator convert StaticNodeList that querySelectorAll returns to array of spans, and then use map operator to get list of items.
See example bellow
([...document.querySelectorAll('#test span')]).map(x => console.log(x.innerHTML))
_x000D_
<div id="test">_x000D_
<span>1</span>_x000D_

<span>4</span>_x000D_

I had a very similar issue. I got the same error because the csv contained spaces in the header. My csv contained a header "Gender " and I had it listed as:
[['Gender']]
If it's easy enough for you to access your csv, you can use the excel formula trim()
to clip any spaces of the cells.
or remove it like this
df.columns = df.columns.to_series().apply(lambda x: x.strip())

jQuery Validation Unobtrusive Native is a collection of ASP.Net MVC HTML helper extensions. These make use of jQuery Validation's native support for validation driven by HTML 5 data attributes. Microsoft shipped jquery.validate.unobtrusive.js back with MVC 3. It provided a way to apply data model validations to the client side using a combination of jQuery Validation and HTML 5 data attributes (that's the "unobtrusive" part).
You can create a single script that calls all the others.
Put the following into a batch file:
@echo off
echo.>"%~dp0all.sql"
for %%i in ("%~dp0"*.sql) do echo @"%%~fi" >> "%~dp0all.sql"
When you run that batch file it will create a new script named all.sql
in the same directory where the batch file is located. It will look for all files with the extension .sql
in the same directory where the batch file is located.
You can then run all scripts by using sqlplus user/pwd @all.sql
(or extend the batch file to call sqlplus
after creating the all.sql
script)
this code works and dont throw any exception:
Session.Abandon(); Session["tempKey1"] = "tempValue1";
It's because when the Abandon method is called, the current Session object is queued for deletion but is not actually deleted until all of the script commands on the current page have been processed. This means that you can access variables stored in the Session object on the same page as the call to the Abandon method but not in any subsequent Web pages.
For example, in the following script, the third line prints the value Mary. This is because the Session object is not destroyed until the server has finished processing the script.
<%
Session.Abandon
Session("MyName") = "Mary"
Reponse.Write(Session("MyName"))
%>
If you access the variable MyName on a subsequent Web page, it is empty. This is because MyName was destroyed with the previous Session object when the page containing the previous example finished processing.

To create a "drop down menu" you can use OptionMenu
in tkinter
Example of a basic OptionMenu
:
from Tkinter import *
master = Tk()
variable = StringVar(master)
variable.set("one") # default value
w = OptionMenu(master, variable, "one", "two", "three")
w.pack()
mainloop()
More information (including the script above) can be found here.
Creating an OptionMenu
of the months from a list would be as simple as:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
mainloop()
In order to retrieve the value the user has selected you can simply use a .get()
on the variable that we assigned to the widget, in the below case this is variable
:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
def ok():
print ("value is:" + variable.get())
button = Button(master, text="OK", command=ok)
button.pack()
mainloop()
I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.
You must know the source encoding.
string someText = "The quick brown fox jumps over the lazy dog.";
byte[] bytes = Encoding.Unicode.GetBytes(someText);
char[] chars = Encoding.Unicode.GetChars(bytes);
on Windows F9 to run single line
Select the lines which you want to run on console and press F9 button for multi line
One difference, that can be an advantage, is that if we are looking for a key that doesn't exist we will get None, not like when we use the brackets notation, in which case we will get an error thrown:
print(dictionary.get("address")) # None
print(dictionary["address"]) # throws KeyError: 'address'
Last thing that is cool about the get method, is that it receives an additional optional argument for a default value, that is if we tried to get the score value of a student, but the student doesn't have a score key we can get a 0 instead.
So instead of doing this (or something similar):
score = None
try:
score = dictionary["score"]
except KeyError:
score = 0
We can do this:
score = dictionary.get("score", 0)
# score = 0
I found it. Perl has multi-line comments:

Member of a class defined with the keyword class
are private
by default. Members of a class defined with the keywords struct
(or union
) are public
by default.
In absence of an access-specifier for a base class, public
is assumed when the derived class is declared struct
and private
is assumed when the class is declared class
.
You can declare an enum class
but not an enum struct
.
You can use template<class T>
but not template<struct T>
.
Note also that the C++ standard allows you to forward-declare a type as a struct
, and then use class
when declaring the type and vice-versa. Also, std::is_class<Y>::value
is true
for Y being a struct
and a class
, but is false
for an enum class
.
One way to do this is to insert a dummy column with the sums in order to sort:
In [10]: sum_B_over_A = df.groupby('A').sum().B
In [11]: sum_B_over_A
Out[11]:
A
bar 0.253652
baz -2.829711
foo 0.551376
Name: B
in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)
In [13]: df
Out[13]:
A B C sum_B_over_A
0 foo 1.624345 False 0.551376
1 bar -0.611756 True 0.253652
2 baz -0.528172 False -2.829711
3 foo -1.072969 True 0.551376
4 bar 0.865408 False 0.253652
5 baz -2.301539 True -2.829711
In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]:
A B C sum_B_over_A
5 baz -2.301539 True -2.829711
2 baz -0.528172 False -2.829711
1 bar -0.611756 True 0.253652
4 bar 0.865408 False 0.253652
3 foo -1.072969 True 0.551376
0 foo 1.624345 False 0.551376
and maybe you would drop the dummy row:
In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z
, but I assume via .format()
.
Anyway, .set()
is using your local time zone, but the Z
in the time string indicates zero time, otherwise known as UTC.
https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators
So I assume your local timezone is 23 hours from UTC?
saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format()
call that outputs using your local timezone, rather than UTC.
http://momentjs.com/docs/#/get-set/
http://momentjs.com/docs/#/displaying/format/
you can try this one
var obj = {
"a": "test1",
"b": "test2"
};
const findSpecificStr = (obj, str) => {
return Object.values(obj).includes(str);
}
findSpecificStr(obj, 'test1');
Not directly answering the question, but does it really have to be a regex?
I used to do lots of Perl, and got used to solving problems with regexes. However, when they get more complicated with all the look-aheads and other quirks, you need to write dozens of unit tests to kill all those little bugs.
Furthermore, a regex is typically a few times slower than an imperative or a functional solution.
For example, the following (not very FP) Scala function solves the original question about three times faster than the regex of the most popular answer. What it does is also so clear that you don't need a unit test at all:
def validatePassword(password: String): Boolean = {
if (password.length < 8)
return false
var lower = false
var upper = false
var numbers = false
var special = false
password.foreach { c =>
if (c.isDigit) numbers = true
else if (c.isLower) lower = true
else if (c.isUpper) upper = true
else special = true
}
lower && upper && numbers && special
}
There is a pretty straight-forward method for T-SQL
, although I'm not sure if it is prestanda-effective if you're skipping a large number of rows.
SELECT TOP numberYouWantToTake
[yourColumns...]
FROM yourTable
WHERE yourIDColumn NOT IN (
SELECT TOP numberYouWantToSkip
yourIDColumn
FROM yourTable
ORDER BY yourOrderColumn
)
ORDER BY yourOrderColumn
If you're using .Net, you can use the following on for example an IEnumerable with your data results:
IEnumerable<yourDataType> yourSelectedData = yourDataInAnIEnumerable.Skip(nubmerYouWantToSkip).Take(numberYouWantToTake);
This has the backside that you're getting all the data from the data storage.
$encoded_url = str_replace('%2F', '/', urlencode($url));
copy your file in linux Java directory
cp yourfile.jar /java/bin
open the directory
cd /java/bin
and execute your file
./java -jar yourfile.jar
or all in one try this command:
/java/bin/java -jar jarfilefolder/jarfile.jar
I guess something like this should do it. It basically writes the content to a new file and replaces the old file with the new file:
from tempfile import mkstemp
from shutil import move, copymode
from os import fdopen, remove
def replace(file_path, pattern, subst):
#Create temp file
fh, abs_path = mkstemp()
with fdopen(fh,'w') as new_file:
with open(file_path) as old_file:
for line in old_file:
new_file.write(line.replace(pattern, subst))
#Copy the file permissions from the old file to the new file
copymode(file_path, abs_path)
#Remove original file
remove(file_path)
#Move new file
move(abs_path, file_path)
Here's a simple and clean function that returns the file size.
long get_file_size(char *path)
{
FILE *fp;
long size = -1;
/* Open file for reading */
fp = fopen(path, "r");
fseek(fp, 0, SEEK_END);
size = ftell(fp);
fp.close();
return
}
Open Sql server 2014 Configuration Manager.
Click Sql server services and start the sql server service if it is stopped
Then click Check SQL server Network Configuration for TCP/IP Enabled
then restart the sql server management studio (SSMS) and connect your local database engine
The query execution happens on all get methods like
$this->db->get('table_name');
$this->db->get_where('table_name',$array);
While last_query contains the last query which was run
$this->db->last_query();
If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions
public function _compile_select($select_override = FALSE)
public function _reset_select()
Now you can write query and get it in a variable
$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();
Now reset query so if you want to write another query the object will be cleared.
$this->db->_reset_select();
And the thing is done. Cheers!!! Note : While using this way you must use
$this->db->from('myTable')
instead of
$this->db->get('myTable')
which runs the query.
For an earlier version of junit, you can do
Class<Map<String, String>> mapClass = (Class) Map.class;
ArgumentCaptor<Map<String, String>> mapCaptor = ArgumentCaptor.forClass(mapClass);
You need to first cast the instance to any
because Function
's type definition does not have a name
property.
class MyClass {
getName() {
return (<any>this).constructor.name;
// OR return (this as any).constructor.name;
}
}
// From outside the class:
var className = (<any>new MyClass()).constructor.name;
// OR var className = (new MyClass() as any).constructor.name;
console.log(className); // Should output "MyClass"
// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"
With TypeScript 2.4 (and potentially earlier) the code can be even cleaner:
class MyClass {
getName() {
return this.constructor.name;
}
}
// From outside the class:
var className = (new MyClass).constructor.name;
console.log(className); // Should output "MyClass"
// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"
The answer with for
is correct, but if you really want to use functional style avoiding for
statement - you can use the following instead of your expression:
Array.from(Array(1000000), () => Math.random());
The Array.from() method creates a new Array instance from an array-like or iterable object. The second argument of this method is a map function to call on every element of the array.
Following the same idea you can rewrite it using ES2015 Spread operator:
[...Array(1000000)].map(() => Math.random())
In both examples you can get an index of the iteration if you need, for example:
[...Array(1000000)].map((_, i) => i + Math.random())
Not possible with standard unix commands. You might have luck with a file recovery utility. Also, be aware, using rm changes the table of contents to mark those blocks as available to be overwritten, so simply using your computer right now risks those blocks being overwritten permanently. If it's critical data, you should turn off the computer before the file sectors gets overwritten. Good luck!

Use an int and increment it within your loop.
I've made very simple function for marquee. See: http://jsfiddle.net/vivekw/pHNpk/2/ It pauses on mouseover & resumes on mouseleave. Speed can be varied. Easy to understand.
function marquee(a, b) {
var width = b.width();
var start_pos = a.width();
var end_pos = -width;
function scroll() {
if (b.position().left <= -width) {
b.css('left', start_pos);
scroll();
}
else {
time = (parseInt(b.position().left, 10) - end_pos) *
(10000 / (start_pos - end_pos)); // Increase or decrease speed by changing value 10000
b.animate({
'left': -width
}, time, 'linear', function() {
scroll();
});
}
}
b.css({
'width': width,
'left': start_pos
});
scroll(a, b);
b.mouseenter(function() { // Remove these lines
b.stop(); //
b.clearQueue(); // if you don't want
}); //
b.mouseleave(function() { // marquee to pause
scroll(a, b); //
}); // on mouse over
}
$(document).ready(function() {
marquee($('#display'), $('#text')); //Enter name of container element & marquee element
});
Your data type is DECIMAL with decimal places, say DECIMAL(10,2). The values in your database are 12, 15, 18, and 20.
12 is the same as 12.0 and 12.00 and 12.000 . It is up to the tool you are using to select the data with, how to display the numbers. Yours either defaults to two digits for decimals or it takes the places from your data definition.
If you only want integers in your column, then change its data type to INT. It makes no sense to use DECIMAL then.
If you want integers and decimals in that column then stay with the DECIMAL type. If you don't like the way you are shown the values, then format them in your application. It's up to that client program to decide for instance if to display point or comma for the decimal separator. (The database can be used from different locations.)
Also don't rely on any database or session settings like a decimal separator being a point and not a comma and then use REPLACE on it. That can work for one person and not for the other.
I'd like to share my debugging process because I was stuck on this issue for at least an hour. Image could not be found when running local host. To add some context, I am styling within a rails app in the following directory:
apps/assets/stylesheets/main.scss
I wanted to render background image in header tag. The following was my original implementation.
header {
text-align: center;
background: linear-gradient(90deg, #d4eece, #d4eece, #d4eece),
url('../images/header.jpg') no-repeat;
background-blend-mode: multiply;
background-size: cover;
}
...as a result I was getting the following error in rails server and the console in Chrome dev tools, respectively:
ActionController::RoutingError (No route matches [GET] "/images/header.jpg")
GET http://localhost:3000/images/header.jpg 404 (Not Found)
I tried different variations of the url:
url('../images/header.jpg') # DID NOT WORK
url('/../images/header.jpg') # DID NOT WORK
url('./../images/header.jpg') # DID NOT WORK
and it still did not work. At that point, I was very confused...I decided to move the image folder from the assets directory (which is the default) to within the stylesheets directory, and tried the following variations of the url:
url('/images/header.jpg') # DID NOT WORK
url('./images/header.jpg') # WORKED
url('images/header.jpg') # WORKED
I no longer got the console and rails server error. But the image still was not showing for some reason. After temporarily giving up, I found out the solution to this was to add a height property in order for the image to be shown...
header {
text-align: center;
height: 390px;
background: linear-gradient(90deg, #d4eece, #d4eece, #d4eece),
url('images/header.jpg') no-repeat;
background-blend-mode: multiply;
background-size: cover;
}
Unfortunately, I am still not sure why the 3 initial url attempts with "../images/header.jpg" did not work on localhost, or when I should or shouldn't be adding a period at the beginning of the url.
It might have something to do with how the default link tag is setup in application.html.erb, or maybe it's a .scss vs .css thing. Or, maybe that's just how the background property with url() works (the image needs to be within same directory as the css file)? Anyhow, this is how I solved the issue with CSS background image not loading on localhost.

A little bit late for this question, but if you:
cat /path/to/repo/.git/config
You will see the url of the repository which will include the reponame:

filemode = true
bare = false
logallrefupdates = true
ignorecase = true
precomposeunicode = true
[remote "origin"]

fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
Now (2021) the preferred way to use istanbul is via its "state of the art command line interface" nyc.
First, install it in your project with
npm i nyc --save-dev
Then, if you have a npm based project, just change the test script inside the scripts
object of your package.json file to execute code coverage of your mocha tests:
{
"scripts": {
"test": "nyc --reporter=text mocha"
}
}
Now run your tests
npm test
and you will see a table like this in your console, just after your tests output:
Just use
nyc --reporter=html
instead of text
. Now it will produce a report inside ./coverage/index.html
.
Istanbul supports a wide range of report formats. Just look at its reports library to find the most useful for you.
Just add a --reporter=REPORTER_NAME
option for each format you want.
For example, with
nyc --reporter=html --reporter=text
you will have both the console and the html report.
Just add another script in your package.json
and leave the test
script with only your test runner (e.g. mocha):
{
"scripts": {
"test": "mocha",
"test-with-coverage": "nyc --reporter=text mocha"
}
}
Now run this custom script
npm run test-with-coverage
to run tests with code coverage.
Fail if the total code coverage is below 90%:
nyc --check-coverage --lines 90
Fail if the code coverage of at least one file is below 90%:
nyc --check-coverage --lines 90 --per-file

I have written a tool to automatically strong-name sign assemblies including ones you do not have the source code for or projects that have been abandoned. It uses many of the techniques described in the answers in a simple way without any of the flaws or drawbacks of existing tools or dated instructions.
http://brutaldev.com/post/2013/10/18/NET-Assembly-Strong-Name-Signer
Hope this helps out anyone that need to sign a third party assembly without having to jump through hoops to get there.
I had to include "PROJECT_NAME/osdep.h" and that includes the os specific configurations.
I would look in other files using the types you are interested in and find where/how they are defined (by looking at includes).
Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.
Gantt chart for this ques will be:
| P3 | P2 | P4 | P5 | P1 |
1 4 5 7 11 14
Average waiting time=(0+2+2+3+3)/5=2
Average Turnaround time=(3+3+4+7+6)/5=4.6
You might be able to use the following for decoding, compressing and saving an image:
@Override
public void onClick(View view) {
onItemSelected1();
InputStream image_stream = null;
try {
image_stream = getContentResolver().openInputStream(myUri);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap image= BitmapFactory.decodeStream(image_stream );
// path to sd card
File path=Environment.getExternalStorageDirectory();
//create a file
File dir=new File(path+"/ComDec/");
dir.mkdirs();
Date date=new Date();
File file=new File(dir,date+".jpg");
OutputStream out=null;
try{
out=new FileOutputStream(file);
image.compress(format,size,out);
out.flush();
out.close();
MediaStore.Images.Media.insertImage(getContentResolver(), image," yourTitle "," yourDescription");
image=null;
}
catch (IOException e)
{
e.printStackTrace();
}
Toast.makeText(SecondActivity.this,"Image Save Successfully",Toast.LENGTH_LONG).show();
}
});
The GO command isn't a Transact-SQL statement, but a special command recognized by several MS utilities including SQL Server Management Studio code editor.
The GO command is used to group SQL commands into batches which are sent to the server together. The commands included in the batch, that is, the set of commands since the last GO command or the start of the session, must be logically consistent. For example, you can't define a variable in one batch and then use it in another since the scope of the variable is limited to the batch in which it's defined.
For more information, see http://msdn.microsoft.com/en-us/library/ms188037.aspx.
Store your results in variables, and use them in your HTML and add the necessary styling.
$usercity = $ip['cityName'];
$usercountry = $ip['countryName'];
And in the HTML, you could do:
<div id="userdetails">
<p> User's IP: <?php echo $usercity; ?> </p>
<p> Country: <?php echo $usercountry; ?> </p>
</div>
Now, you can simply add the styles for country
class in your CSS, like so:
#userdetails {
/* styles go here */
}
Alternatively, you could also use this in your HTML:
<p style="font-size:15px; font-color: green;"><?php echo $userip; ?> </p>
<p style="font-size:15px; font-color: green;"><?php echo $usercountry; ?> </p>
Hope this helps!
You can use varStatus in your c:forEach loop
In your first example you can get the counter to work properly as follows...
<c:forEach var="tableEntity" items='${requestScope.tables}'>
<c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="count">
my count is ${count.count}
</c:forEach>
</c:forEach>
You can probably use the KeyDown event, KeyPress event or KeyUp event. I would first try the KeyDown event I think.
You can set the Handled property of the event args to stop handling the event.
I know it's a little late for this. But I always thought that the best way to create event listeners is directly from JavaScript. Kind of like not applying inline CSS styles.
function validate(){
//do stuff
}
function init(){
document.getElementById('form').onsubmit = validate;
}
window.onload = init;
That way you don't have a bunch of event listeners throughout your HTML.
Copy from php.net sample for inclusive range:
$begin = new DateTime( '2012-08-01' );
$end = new DateTime( '2012-08-31' );
$end = $end->modify( '+1 day' );
$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);
foreach($daterange as $date){
echo $date->format("Ymd") . "<br>";
}

BYTE
I am trying to answer this question from C++ perspective.
The C++ standard defines ‘byte’ as “Addressable unit of data large enough to hold any member of the basic character set of the execution environment.”
What this means is that the byte consists of at least enough adjacent bits to accommodate the basic character set for the implementation. That is, the number of possible values must equal or exceed the number of distinct characters. In the United States, the basic character sets are usually the ASCII and EBCDIC sets, each of which can be accommodated by 8 bits. Hence it is guaranteed that a byte will have at least 8 bits.
In other words, a byte is the amount of memory required to store a single character.
If you want to verify ‘number of bits’ in your C++ implementation, check the file ‘limits.h’. It should have an entry like below.
#define CHAR_BIT 8 /* number of bits in a char */
WORD
A Word is defined as specific number of bits which can be processed together (i.e. in one attempt) by the machine/system. Alternatively, we can say that Word defines the amount of data that can be transferred between CPU and RAM in a single operation.
The hardware registers in a computer machine are word sized. The Word size also defines the largest possible memory address (each memory address points to a byte sized memory).
Note – In C++ programs, the memory addresses points to a byte of memory and not to a word.
It was suggested to post this as an answer, because some other answers are giving errors like 'The name Context does not exist in the current context'.
Just using the following works:
Request.Query["queryparm1"]
Sample usage:
<a href="@Url.Action("Query",new {parm1=Request.Query["queryparm1"]})">GO</a>
I have slightly improved answer, which handles extended CSS definitions like:
background-image: url(http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png), -webkit-linear-gradient(top, rgb(81, 127, 164), rgb(48, 96, 136))
JavaScript code:
var bg = $("div").css("background-image")
bg = bg.replace(/.*\s?url\([\'\"]?/, '').replace(/[\'\"]?\).*/, '')
Result:
"http://d36xtkk24g8jdx.cloudfront.net/bluebar/359de8f/images/shared/noise-1.png"
I'll explain it in a simple way.
Generics defined at Class level are completely separate from the generics defined at the (static) method level.
class Greet<T> {
public static <T> void sayHello(T obj) {
System.out.println("Hello " + obj);
}
}
When you see the above code anywhere, please note that the T defined at the class level has nothing to do with the T defined in the static method. The following code is also completely valid and equivalent to the above code.
class Greet<T> {
public static <E> void sayHello(E obj) {
System.out.println("Hello " + obj);
}
}
Why the static method needs to have its own generics separate from those of the Class?
This is because, the static method can be called without even instantiating the Class. So if the Class is not yet instantiated, we do not yet know what is T. This is the reason why the static methods needs to have its own generics.
So, whenever you are calling the static method,
Greet.sayHello("Bob");
Greet.sayHello(123);
JVM interprets it as the following.
Greet.<String>sayHello("Bob");
Greet.<Integer>sayHello(123);
Both giving the same outputs.
Hello Bob
Hello 123
Although many great answers were written to this question, none of them uses the Rspec tags
approach.
I use tags to run one or more specs in different files -- only those related to my current development task.
For example, I add the tag "dev" with the value "current":
it "creates an user", dev: :current do
user = create(:user)
expect(user.persisted?).to be_truthy
end
then I run
bundle exec rspec . --tag dev:current
Different tags/values can be set in individual specs or groups.
Unix uses 0xA for a newline character. Windows uses a combination of two characters: 0xD 0xA. 0xD is the carriage return character. ^M
happens to be the way vim displays 0xD (0x0D = 13, M is the 13th letter in the English alphabet).
You can remove all the ^M
characters by running the following:
:%s/^M//g
Where ^M
is entered by holding down Ctrl and typing v followed by m, and then releasing Ctrl. This is sometimes abbreviated as ^V^M
, but note that you must enter it as described in the previous sentence, rather than typing it out literally.
This expression will replace all occurrences of ^M
with the empty string (i.e. nothing). I use this to get rid of ^M
in files copied from Windows to Unix (Solaris, Linux, OSX).

With C# 7, which shipped with Visual Studio 2017 (Release 15.*), you are able to use Types in case
statements (pattern matching):
switch(shape)
{
case Circle c:
WriteLine($"circle with radius {c.Radius}");
break;
case Rectangle s when (s.Length == s.Height):
WriteLine($"{s.Length} x {s.Height} square");
break;
case Rectangle r:
WriteLine($"{r.Length} x {r.Height} rectangle");
break;
default:
WriteLine("<unknown shape>");
break;
case null:
throw new ArgumentNullException(nameof(shape));
}
With C# 6, you can use a switch statement with the nameof() operator (thanks @Joey Adams):
switch(o.GetType().Name) {
case nameof(AType):
break;
case nameof(BType):
break;
}
With C# 5 and earlier, you could use a switch statement, but you'll have to use a magic string containing the type name... which is not particularly refactor friendly (thanks @nukefusion)
switch(o.GetType().Name) {
case "AType":
break;
}
The answer from Randal Schwartz almost helped me all the way. I have a different username on the server, so I had to add the User keyword to my file:
Host friendly-name
HostName long.and.cumbersome.server.name
IdentityFile ~/.ssh/private_ssh_file
User username-on-remote-machine
Now you can connect using the friendly-name:
ssh friendly-name
More keywords can be found on the OpenSSH man page. NOTE: Some of the keywords listed might already be present in your /etc/ssh/ssh_config file.
For running c++ files run below command, Assuming file name is "main.cpp"
1.Compile to make object file from c++ file.
g++ -c main.cpp -o main.o
2.Since #include <conio.h>
does not support in MacOS so we should use its alternative which supports in Mac that is #include <curses.h>
. Now object file needs to be converted to executable file. To use curses.h
we have to use library -lcurses
.
g++ -o main main.o -lcurses
3.Now run the executable.
./main
Hang on, doesn't removeClass() default to removing all classes if nothing specific is specified? So

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.
if someone needs for interest calculation year in float format

If you are going to call relative.py
directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path
list.
Here is how it should work:
# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')
# Now you can do imports from one directory top cause it is in the sys.path
import parent
# And even like this:
from parent import Parent
If you think the above can cause some kind of inconsistency you can use this instead:
sys.path.append(sys.path[0] + "/..")
sys.path[0]
refers to the path that the entry point was ran from.
If you happen to need this in Android and want to make it work with anything older than FroYo, you can also use EncodingUtils.getAsciiBytes():
byte[] bytes = EncodingUtils.getAsciiBytes("ASCII Text");
JSON has no functions as data types. You can only serialize strings, numbers, objects, arrays, and booleans (and null
)
You could create your own toJson
method, only passing the data that really has to be serialized:
Person.prototype.toJson = function() {
return JSON.stringify({age: this.age});
};
Similar for deserializing:
Person.fromJson = function(json) {
var data = JSON.parse(json); // Parsing the json string.
return new Person(data.age);
};
The usage would be:
var serialize = p1.toJson();
var _p1 = Person.fromJson(serialize);
alert("Is old: " + _p1.isOld());
To reduce the amount of work, you could consider to store all the data that needs to be serialized in a special "data" property for each Person
instance. For example:
function Person(age) {
this.data = {
age: age
};
this.isOld = function (){
return this.data.age > 60 ? true : false;
}
}
then serializing and deserializing is merely calling JSON.stringify(this.data)
and setting the data of an instance would be instance.data = JSON.parse(json)
.
This would keep the toJson
and fromJson
methods simple but you'd have to adjust your other functions.
Side note:
You should add the isOld
method to the prototype of the function:
Person.prototype.isOld = function() {}
Otherwise, every instance has it's own instance of that function which also increases memory.
This is behavior specified in the Java API's String.valueOf(Object)
method. When you do concatenation, valueOf
is used to get the String
representation. There is a special case if the Object is null
, in which case the string "null"
is used.
public static String valueOf(Object obj)
Returns the string representation of the Object argument.
Parameters: obj - an Object.
Returns:
if the argument is null, then a string equal to "null"; otherwise, the value of obj.toString() is returned.
There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.
If you have a long running background work you should specify this by using the correct Task Option.
You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.
The update from 3.2.x to 3.3.x broke some of the solutions explained here and on other threads because of the change: "Added transforms to improve carousel performance in modern browsers."
If you are using Bootstrap 3.3.x there's a solution here:
http://codepen.io/transportedman/pen/NPWRGq
Basically you need to add the "carousel-fade" class to your carousel so that you have:
<div class="carousel slide carousel-fade">
And then include the following CSS:

contentType
option to false
is used for multipart/form-data
forms that pass files.
When one sets the contentType
option to false
, it forces jQuery not to add a Content-Type header, otherwise, the boundary string will be missing from it. Also, when submitting files via multipart/form-data, one must leave the processData
flag set to false, otherwise, jQuery will try to convert your FormData into a string, which will fail.
Use jQuery's .serialize()
method which creates a text string in standard URL-encoded notation.
You need to pass un-encoded data when using contentType: false
.
Try using new FormData
instead of .serialize():
var formData = new FormData($(this)[0]);
See for yourself the difference of how your formData is passed to your php page by using console.log()
.
var formData = new FormData($(this)[0]);
console.log(formData);
var formDataSerialized = $(this).serialize();
console.log(formDataSerialized);
To obtain a stream of just the names:
$ jq '.[] | select(.location=="Stockholm") | .name' json
produces:
"Donald"
"Walt"
To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:
$ jq -c 'to_entries[]
| select (.value.location == "Stockholm")
| [.key, .value.name]' json
Output:
["FOO","Donald"]
["BAR","Walt"]
Swap should take place on the Instance Storage (ephemeral) disk and not an EBS device. Swapping will cause a lot of IO and will increase cost on EBS. EBS is also slower than the Instance Store and the Instance Store comes free with certain types of EC2 Instances.
It will usually be mounted to /mnt but if not run
sudo mount /dev/xvda2 /mnt
To then create a swap file on this device do the following for a 4GB swapfile
sudo dd if=/dev/zero of=/mnt/swapfile bs=1M count=4096
Make sure no other user can view the swap file
sudo chown root:root /mnt/swapfile
sudo chmod 600 /mnt/swapfile
Make and Flag as swap
sudo mkswap /mnt/swapfile
sudo swapon /mnt/swapfile
Add/Make sure the following are in your /etc/fstab
/dev/xvda2 /mnt auto defaults,nobootwait,comment=cloudconfig 0 2
/mnt/swapfile swap swap defaults 0 0
lastly enable swap
sudo swapon -a
Another way of accomplishing this is using animation
which provides more control.
#content #nav a {
background-color: #FF0;
/* only animation-duration here is required, rest are optional (also animation-name but it will be set on hover)*/
animation-duration: 1s; /* same as transition duration */
animation-timing-function: linear; /* kind of same as transition timing */
animation-delay: 0ms; /* same as transition delay */
animation-iteration-count: 1; /* set to 2 to make it run twice, or Infinite to run forever!*/
animation-direction: normal; /* can be set to "alternate" to run animation, then run it backwards.*/
animation-fill-mode: none; /* can be used to retain keyframe styling after animation, with "forwards" */
animation-play-state: running; /* can be set dynamically to pause mid animation*/
/* declaring the states of the animation to transition through */
/* optionally add other properties that will change here, or new states (50% etc) */
@keyframes onHoverAnimation {
0% {
background-color: #FF0;
}
100% {
background-color: #AD310B;
}
}
}
#content #nav a:hover {
/* animation wont run unless the element is given the name of the animation. This is set on hover */
animation-name: onHoverAnimation;
}
You would need to enable https binding on server side. IISExpress in this case. Select Properties on website project in solution explorer (not double click). In the properties pane then you need to enable SSL.
I ran into this problem today and I needed it on Solaris so here is a POSIX standard way to do (something very close to) this.
#Detect OS
UNAME = `uname`
# Build based on OS name
DetectOS:
-@make $(UNAME)
# OS is Linux, use GCC
Linux: program.c
@SHELL_VARIABLE="-D_LINUX_STUFF_HERE_"
rm -f program
gcc $(SHELL_VARIABLE) -o program program.c
# OS is Solaris, use c99
SunOS: program.c
@SHELL_VARIABLE="-D_SOLARIS_STUFF_HERE_"
rm -f program
c99 $(SHELL_VARIABLE) -o program program.c
Well you don't really have to worry about IE7 code not working in IE8 because IE8 has compatibility mode (it can render pages the same as IE7). But if you still want to target different versions of IE, a way that's been done for a while now is to either use conditional comments or begin your css rule with a * to target IE7 and below. Or you could pay attention to user agent on the servers and dish up a different CSS file based on that information.
I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.
Your code doesn't seem so ugly to me...
however, an alternative (not much better) could be e.g. :
df <- data.frame(table(yn))
colnames(df) <- c('Smoker','Freq')
df$Perc <- df$Freq / sum(df$Freq) * 100
------------------
Smoker Freq Perc
1 No 19 47.5
2 Yes 21 52.5
Response.Redirect()
will send you to a new page, update the address bar and add it to the Browser History. On your browser you can click back.
Server.Transfer()
does not change the address bar. You cannot hit back.
I use Server.Transfer()
when I don't want the user to see where I am going. Sometimes on a "loading" type page.
Otherwise I'll always use Response.Redirect()
.
first, create a class to hold your parameters:
public class PkRk {
public int pk { get; set; }
public int rk { get; set; }
}
then, use the Html.Action
passing the parameters:
Html.Action("PkRkAction", new { pkrk = new PkRk { pk=400, rk=500} })
and use in Controller:
public ActionResult PkRkAction(PkRk pkrk) {
return PartialView(pkrk);
}
you can use this code as template please customize it as per your requirement.
DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();
list.add(textField.getText());
list.add(comboBox.getSelectedItem());
model.addRow(list.toArray());
table.setModel(model);
here DefaultTableModel
is used to add rows in JTable
,

Forget setAttribute()
: it's badly broken and doesn't always do what you might expect in old IE (IE <= 8 and compatibility modes in later versions). Use the element's properties instead. This is generally a good idea, not just for this particular case. Replace your code with the following, which will work in all major browsers:
var hiddenInput = document.createElement("input");
hiddenInput.id = "uniqueIdentifier";
hiddenInput.type = "hidden";
hiddenInput.value = ID;
hiddenInput.className = "ListItem";
Update
The nasty hack in the second code block in the question is unnecessary, and the code above works fine in all major browsers, including IE 6. See http://www.jsfiddle.net/timdown/aEvUT/. The reason why you get null
in your alert()
is that when it is called, the new input is not yet in the document, hence the document.getElementById()
call cannot find it.
Try this it's simple and fast
SELECT T.name AS [TABLE NAME], I.rows AS [ROWCOUNT]
FROM sys.tables AS T
INNER JOIN sys.sysindexes AS I ON T.object_id = I.id
AND I.indid < 2 ORDER BY I.rows DESC
In short, it's because of the IE8 parsing engine.
Guess why Microsoft has trouble working with the new HTML5 tags (like "section") too? It's because MS decided that they will not use regular XML parsing, like the rest of the world. Yes, that's right - they did a ton of propaganda on XML but in the end, they fall back on a "stupid" parsing engine looking for "known tags" and messing stuff up when something new comes around.
Same goes for IE8 and the jquery issue with "load", "get" and "post". Again, Microsoft decided to "walk their own path" with version 8. Hoping that they solve(d) this in IE9, the only current option is to fall back on IE7 parsing with <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
.
Oh well... what a surprise that Microsoft made us post stuff on forums again. ;)
All other answers here depends on adding code the the notebook(!)
In my opinion is bad practice to hardcode a specific path into the notebook code, or otherwise depend on the location, since this makes it really hard to refactor you code later on. Instead I would recommend you to add the root project folder to PYTHONPATH when starting up your Jupyter notebook server, either directly from the project folder like so
env PYTHONPATH=`pwd` jupyter notebook
or if you are starting it up from somewhere else, use the absolute path like so
env PYTHONPATH=/Users/foo/bar/project/ jupyter notebook
Well you can use below command to export,
mysqldump --databases --user=root --password your_db_name > export_into_db.sql
and the generated file will be available in the same directory where you had ran this command.
Now login to mysql using command,
mysql -u[username] -p
then use "source" command with the file path.
It sounds like you have installed SQL Server 2005 Express Edition, which does not include SSIS or the Business Intelligence Development Studio.
BIDS is only provided with the (not free) Standard, Enterprise and Developer Editions.
EDIT
This information was correct for SQL Server 2005. Since SQL Server 2014, Developer Edition has been free. BIDS has been replaced by SQL Server Data Tools, a free plugin for Visual Studio (including the free Visual Studio Community Edition).

Just add createDatabaseIfNotExist=true parameter in spring datasource url
Example: spring.datasource.url= jdbc:mysql://localhost:3306/test?createDatabaseIfNotExist=true
Use DBNull.Value.Equals on the object without converting it to a string.
Here's an example:
if (! DBNull.Value.Equals(row[fieldName]))
{
//not null
}
else
{
//null
}
Using the attribute method is, in fact, easier and more straightforward.
Using Ruby with the Selenium and PageObject gems, to get the class associated with a certain element, the line would be element.attribute(Class)
.
The same concept applies if you wanted to get other attributes tied to the element. For example, if I wanted the string of an element, element.attribute(String)
.
Try this:
Select
Id,
Salt,
Password,
BannedEndDate,
(Select Count(*)
From LoginFails
Where username = '" + LoginModel.Username + "' And IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "')
From Users
Where username = '" + LoginModel.Username + "'
And I recommend you strongly to use parameters in your query to avoid security risks with sql injection attacks!
Hope that helps!
I needed a solution to convert columns to rows in Microsoft SQL Server, without knowing the colum names (used in trigger) and without dynamic sql (dynamic sql is too slow for use in a trigger).
I finally found this solution, which works fine:
SELECT
insRowTbl.PK,
insRowTbl.Username,
attr.insRow.value('local-name(.)', 'nvarchar(128)') as FieldName,
attr.insRow.value('.', 'nvarchar(max)') as FieldValue
FROM ( Select
i.ID as PK,
i.LastModifiedBy as Username,
convert(xml, (select i.* for xml raw)) as insRowCol
FROM inserted as i
) as insRowTbl
CROSS APPLY insRowTbl.insRowCol.nodes('/row/@*') as attr(insRow)
As you can see, I convert the row into XML (Subquery select i,* for xml raw, this converts all columns into one xml column)
Then I CROSS APPLY a function to each XML attribute of this column, so that I get one row per attribute.
Overall, this converts columns into rows, without knowing the column names and without using dynamic sql. It is fast enough for my purpose.
(Edit: I just saw Roman Pekar answer above, who is doing the same. I used the dynamic sql trigger with cursors first, which was 10 to 100 times slower than this solution, but maybe it was caused by the cursor, not by the dynamic sql. Anyway, this solution is very simple an universal, so its definitively an option).
I am leaving this comment at this place, because I want to reference this explanation in my post about the full audit trigger, that you can find here: https://stackoverflow.com/a/43800286/4160788
The Newline in T-SQL is represented by CHAR(13) & CHAR(10) (Carriage return + Line Feed). Accordingly, you can create a REPLACE statement with the text you want to replace the newline with.
REPLACE(MyField, CHAR(13) + CHAR(10), 'something else')
Rewrite @Juned Ahsan solution via stream in one line (headers are treated the same way):
public static String printRequest(HttpServletRequest req) {
String params = StreamSupport.stream(
((Iterable<String>) () -> req.getParameterNames().asIterator()).spliterator(), false)
.map(pName -> pName + '=' + req.getParameter(pName))
.collect(Collectors.joining("&"));
return req.getRequestURI() + '?' + params;
}

A simple modal pop up div or dialog box can be done by CSS properties and little bit of jQuery.The basic idea is simple:
So we need three divs:
First let us define the CSS:
#hider
{
position:absolute;
top: 0%;
left: 0%;
width:1600px;
height:2000px;
margin-top: -800px; /*set to a negative number 1/2 of your height*/
margin-left: -500px; /*set to a negative number 1/2 of your width*/
/*
z- index must be lower than pop up box
*/
z-index: 99;
background-color:Black;
//for transparency
opacity:0.6;
}
#popup_box
{
position:absolute;
top: 50%;
left: 50%;
width:10em;
height:10em;
margin-top: -5em; /*set to a negative number 1/2 of your height*/
margin-left: -5em; /*set to a negative number 1/2 of your width*/
border: 1px solid #ccc;
border: 2px solid black;
z-index:100;
}
It is important that we set our hider div's z-index lower than pop_up box as we want to show popup_box on top.
Here comes the java Script:
$(document).ready(function () {
//hide hider and popup_box
$("#hider").hide();
$("#popup_box").hide();
//on click show the hider div and the message
$("#showpopup").click(function () {
$("#hider").fadeIn("slow");
$('#popup_box').fadeIn("slow");
});
//on click hide the message and the
$("#buttonClose").click(function () {
$("#hider").fadeOut("slow");
$('#popup_box').fadeOut("slow");
});
});
And finally the HTML:
<div id="hider"></div>
<div id="popup_box">
Message<br />
<a id="buttonClose">Close</a>
</div>
<div id="content">
Page's main content.<br />
<a id="showpopup">ClickMe</a>
</div>
I have used jquery-1.4.1.min.js www.jquery.com/download and tested the code in Firefox. Hope this helps.
As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)
Duration column = End - Start
SELECT TOP 1 column_name, LEN(column_name) AS Lenght FROM table_name ORDER BY LEN(column_name) DESC
You can use do.call:
do.call("<-",list(parameter_name, parameter_value))
