I have had the same problem. I resolved it by disabling the proxy in the SoapUI preferences. (source : http://www.eviware.com/forum/viewtopic.php?f=13&t=12460)
I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:
public static void main(String[] args) {
try {
throw new RuntimeException("Cannot move file");
} catch (Exception ex) {
JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
}
}
...you will see a popup that says exactly what you want.
However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause
:
public static void main(String[] args) {
try {
throw new Exception(new RuntimeException("Cannot move file"));
} catch (Exception ex) {
JOptionPane.showMessageDialog(null,
"Error: " + getRootCause(ex).getMessage());
}
}
public static Throwable getRootCause(Throwable throwable) {
if (throwable.getCause() != null)
return getRootCause(throwable.getCause());
return throwable;
}
Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.
A likely possibility is that your browser reaches your web service through a proxy, and SoapUI is not configured to use that proxy. For example, I work in a corporate environment and while my IE and FireFox can access external websites, my SoapUI can only access internal web services.
The easy solution is to just open the WSDL in a browser, save it to a .xml file, and base your SoapUI project on that. This won't work if your WSDL relies on external XSDs that it can't get to, however.
Any suggestions/examples? I followed
SwingWorker
... The code was very messy and I don't like this approach.
Instead of get()
, which waits for completion, use process()
and setProgress()
to show intermediate results, as suggested in this simple example or this related example.
The code is very long so I can't paste all the code.
There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.
You need to create a SSCCE to post on the forum.
So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.
Learn how the basice work first before writing a 200 line program.
Learn how to do some basic debugging, we are not mind readers. We can't guess what silly mistake you are doing based on your verbal description of the problem.
There is an easier way. Just pass your string date to the following function, it will give you the day name :)
func getDayNameBy(stringDate: String) -> String
{
let df = NSDateFormatter()
df.dateFormat = "YYYY-MM-dd"
let date = df.dateFromString(stringDate)!
df.dateFormat = "EEEE"
return df.stringFromDate(date);
}
A quick string "GOTCHA" with JSON Unmarshall which will add wrapping quotes to strings.
(example: the string value of {"first_name":" I have whitespace "}
will convert to "\" I have whitespace \""
)
Before you can trim anything, you'll need to remove the extra quotes first:
// ScrubString is a string that might contain whitespace that needs scrubbing.
type ScrubString string
// UnmarshalJSON scrubs out whitespace from a valid json string, if any.
func (s *ScrubString) UnmarshalJSON(data []byte) error {
ns := string(data)
// Make sure we don't have a blank string of "\"\"".
if len(ns) > 2 && ns[0] != '"' && ns[len(ns)] != '"' {
*s = ""
return nil
}
// Remove the added wrapping quotes.
ns, err := strconv.Unquote(ns)
if err != nil {
return err
}
// We can now trim the whitespace.
*s = ScrubString(strings.TrimSpace(ns))
return nil
}
This works for me. I discovered it when I had to work with DateTime.Date to get only the date part.
var wholeDate = DateTime.Parse("6/22/2009 10:00:00 AM");
var time = wholeDate - wholeDate.Date;
This is another version which really does not have any restrictions (e.g.: special chars when using xml approach, number of records in CTE approach) and it runs much faster based on a test on 10M+ records with source string average length of 4000. Hope this could help.
Create function [dbo].[udf_split] (
@ListString nvarchar(max),
@Delimiter nvarchar(1000),
@IncludeEmpty bit)
Returns @ListTable TABLE (ID int, ListValue nvarchar(1000))
AS
BEGIN
Declare @CurrentPosition int, @NextPosition int, @Item nvarchar(max), @ID int, @L int
Select @ID = 1,
@L = len(replace(@Delimiter,' ','^')),
@ListString = @ListString + @Delimiter,
@CurrentPosition = 1
Select @NextPosition = Charindex(@Delimiter, @ListString, @CurrentPosition)
While @NextPosition > 0 Begin
Set @Item = LTRIM(RTRIM(SUBSTRING(@ListString, @CurrentPosition, @NextPosition-@CurrentPosition)))
If @IncludeEmpty=1 or LEN(@Item)>0 Begin
Insert Into @ListTable (ID, ListValue) Values (@ID, @Item)
Set @ID = @ID+1
End
Set @CurrentPosition = @NextPosition+@L
Set @NextPosition = Charindex(@Delimiter, @ListString, @CurrentPosition)
End
RETURN
END
Its quite simple. Try this instead:
let myReferenceDiv = document.getElementById('mydiv');
let prev = myReferenceDiv.previousElementSibling;
let next = myReferenceDiv.nextElementSibling;
Although I was expecting an automatic solution (fitting to the screen automatically), resizing solves the problem as well.
import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL) # Create window with freedom of dimensions
im = cv2.imread("earth.jpg") # Read image
imS = cv2.resize(im, (960, 540)) # Resize image
cv2.imshow("output", imS) # Show image
cv2.waitKey(0) # Display the image infinitely until any keypress
What about using git branch -m to rename the master branch to another one, then rename seotweaks branch to master? Something like this:
git branch -m master old-master
git branch -m seotweaks master
git push -f origin master
This might remove commits in origin master, please check your origin master before running git push -f origin master
.
The accepted answer is good and fast:
i.ToString("00")
or
i.ToString("000")
If you need more complexity, String.Format is worth a try:
var str1 = "";
var str2 = "";
for (int i = 1; i < 100; i++)
{
str1 = String.Format("{0:00}", i);
str2 = String.Format("{0:000}", i);
}
For the i = 10
case:
str1: "10"
str2: "010"
I use this, for example, to clear the text on particular Label Controls on my form by name:
private void EmptyLabelArray()
{
var fmt = "Label_Row{0:00}_Col{0:00}";
for (var rowIndex = 0; rowIndex < 100; rowIndex++)
{
for (var colIndex = 0; colIndex < 100; colIndex++)
{
var lblName = String.Format(fmt, rowIndex, colIndex);
foreach (var ctrl in this.Controls)
{
var lbl = ctrl as Label;
if ((lbl != null) && (lbl.Name == lblName))
{
lbl.Text = null;
}
}
}
}
}
This was the least bad answer I could come up with.
import org.apache.commons.lang3.tuple.ImmutablePair;
import org.apache.commons.lang3.tuple.Pair;
public class Test {
public static <T, L, R> Pair<L, R> splitStream(Stream<T> inputStream, Predicate<T> predicate,
Function<Stream<T>, L> trueStreamProcessor, Function<Stream<T>, R> falseStreamProcessor) {
Map<Boolean, List<T>> partitioned = inputStream.collect(Collectors.partitioningBy(predicate));
L trueResult = trueStreamProcessor.apply(partitioned.get(Boolean.TRUE).stream());
R falseResult = falseStreamProcessor.apply(partitioned.get(Boolean.FALSE).stream());
return new ImmutablePair<L, R>(trueResult, falseResult);
}
public static void main(String[] args) {
Stream<Integer> stream = Stream.iterate(0, n -> n + 1).limit(10);
Pair<List<Integer>, String> results = splitStream(stream,
n -> n > 5,
s -> s.filter(n -> n % 2 == 0).collect(Collectors.toList()),
s -> s.map(n -> n.toString()).collect(Collectors.joining("|")));
System.out.println(results);
}
}
This takes a stream of integers and splits them at 5. For those greater than 5 it filters only even numbers and puts them in a list. For the rest it joins them with |.
outputs:
([6, 8],0|1|2|3|4|5)
Its not ideal as it collects everything into intermediary collections breaking the stream (and has too many arguments!)
Emulation may seem daunting but is actually quite easier than simulating.
Any processor typically has a well-written specification that describes states, interactions, etc.
If you did not care about performance at all, then you could easily emulate most older processors using very elegant object oriented programs. For example, an X86 processor would need something to maintain the state of registers (easy), something to maintain the state of memory (easy), and something that would take each incoming command and apply it to the current state of the machine. If you really wanted accuracy, you would also emulate memory translations, caching, etc., but that is doable.
In fact, many microchip and CPU manufacturers test programs against an emulator of the chip and then against the chip itself, which helps them find out if there are issues in the specifications of the chip, or in the actual implementation of the chip in hardware. For example, it is possible to write a chip specification that would result in deadlocks, and when a deadline occurs in the hardware it's important to see if it could be reproduced in the specification since that indicates a greater problem than something in the chip implementation.
Of course, emulators for video games usually care about performance so they don't use naive implementations, and they also include code that interfaces with the host system's OS, for example to use drawing and sound.
Considering the very slow performance of old video games (NES/SNES, etc.), emulation is quite easy on modern systems. In fact, it's even more amazing that you could just download a set of every SNES game ever or any Atari 2600 game ever, considering that when these systems were popular having free access to every cartridge would have been a dream come true.
It looks like you probably pasted this (or used a word processor like MS Word) using a kind of double-quotes that are not recognized by the browser. Please check that your code uses actual double-quotes like this one "
, which is different from the following character: ”
Replace the meta tag with this one and try again:

What ever attribute is added to the button/anchor/link to disable it, bootstrap is just adding style to it and user will still be able to click it while there is still onclick event. So my simple solution is to check if it is disabled and remove/add onclick event:
if (!('#button').hasAttr('disabled'))
$('#button').attr('onclick', 'someFunction();');
else
$('#button').removeattr('onclick');
You will have to expand one of your upper views to fill the remaining space by setting android:layout_weight="1"
on it. This will push your last view down to the bottom.
Here is a brief sketch of what I mean:
<LinearLayout android:orientation="vertical">
<View/>
<View android:layout_weight="1"/>
<View/>
<View android:id="@+id/bottom"/>
</LinearLayout>
where each of the child view heights is "wrap_content"
and everything else is "fill_parent"
.
It's currently working, I've just changed the operator >
in order to work in the snippet, take a look:

I solve this the way Below
Animation anim = AnimationUtils.loadAnimation(this, R.anim.slide);
fg.startAnimation(anim);
this.fg.setVisibility(View.VISIBLE); //fg is a View object indicate fragment
An easy workaround might be to simply mount the volume (using the -v or --mount flag) to the container when you run it and access the files that way.
example:
docker run -v /path/to/file/on/host:/desired/path/to/file/in/container/ image_name
for more see: https://docs.docker.com/storage/volumes/
There is a library for this BarCode PHP. You just need to include a few files:
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
You can generate many types of barcodes, namely 1D or 2D. Add the required library:
require_once('class/BCGcode39.barcode.php');
Generate the colours:
// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);
After you have added all the codes, you will get this way:
Example
Since several have asked for an example here is what I was able to do to get it done
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
require_once('class/BCGcode128.barcode.php');
header('Content-Type: image/png');
$color_white = new BCGColor(255, 255, 255);
$code = new BCGcode128();
$code->parse('HELLO');
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
If you want to actually create the image file so you can save it then change
$drawing = new BCGDrawing('', $color_white);
to
$drawing = new BCGDrawing('image.png', $color_white);
Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:
USE master ;
GO
ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO
Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.
If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:
SELECT
name, database_id, is_broker_enabled
FROM sys.databases
<script >
window.onload = setInterval(clock,1000);
function clock()
{
var d = new Date();
var date = d.getDate();
var year = d.getFullYear();
var month = d.getMonth();
var monthArr = ["January", "February","March", "April", "May", "June", "July", "August", "September", "October", "November","December"];
month = monthArr[month];
document.getElementById("date").innerHTML=date+" "+month+", "+year;
}
Try using the count function in dplyr:
library(dplyr)
dat1_frame %>%
count(MONTH.YEAR)
I am not sure how you got MONTH-YEAR as a variable name. My R version does not allow for such a variable name, so I replaced it with MONTH.YEAR.
As a side note, the mistake in your code was that dat1_frame %.% group_by(MONTH-YEAR)
without a summarise
function returns the original data frame without any modifications. So, you want to use
dat1_frame %>%
group_by(MONTH.YEAR) %>%
summarise(count=n())
What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.
You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

JetBrains offer a reasonable explanation,
"Ad-hoc conversion of data structures to text is largely dependent on the current culture, and may lead to unintended results when the code is executed on a machine whose locale differs from that of the original developer. To prevent ambiguities, ReSharper warns you of any instances in code where such a problem may occur."
but if I am working on a site I know will be in English only, I just ignore the suggestion.
I had a similar error message "Fragment MyFragment not attached to Context" in Xamarine Android.
this error messege getting because of this resource calling
button.Text = Resources.GetString(Resource.String.please_wait)
I did fix that by using in Xamarine Android.
if (Context != null && IsAdded){
button.Text = Resources.GetString(Resource.String.please_wait);
}
Solution works very well,
public List<String> savePerson(@RequestBody Person[] personArray)
For this signature you can pass Person
array from postman like
[
{
"empId": "10001",
"tier": "Single",
"someting": 6,
"anything": 0,
"frequency": "Quaterly"
}, {
"empId": "10001",
"tier": "Single",
"someting": 6,
"anything": 0,
"frequency": "Quaterly"
}
]
Don't forget to add consumes
tag:
@RequestMapping(value = "/getEmployeeList", method = RequestMethod.POST, consumes="application/json", produces = "application/json")
public List<Employee> getEmployeeDataList(@RequestBody Employee[] employeearray) { ... }
Using Java 6 or later, the classpath option supports wildcards. Note the following:
"
)*
, not *.jar
Windows
java -cp "Test.jar;lib/*" my.package.MainClass
Unix
java -cp "Test.jar:lib/*" my.package.MainClass
This is similar to Windows, but uses :
instead of ;
. If you cannot use wildcards, bash
allows the following syntax (where lib
is the directory containing all the Java archive files):
java -cp "$(printf %s: lib/*.jar)"
(Note that using a classpath is incompatible with the -jar
option. See also: Execute jar file with multiple classpath libraries from command prompt)
Understanding Wildcards
From the Classpath document:
Class path entries can contain the basename wildcard character
*
, which is considered equivalent to specifying a list of all the files in the directory with the extension.jar
or.JAR
. For example, the class path entryfoo/*
specifies all JAR files in the directory named foo. A classpath entry consisting simply of*
expands to a list of all the jar files in the current directory.A class path entry that contains
*
will not match class files. To match both classes and JAR files in a single directory foo, use eitherfoo;foo/*
orfoo/*;foo
. The order chosen determines whether the classes and resources infoo
are loaded before JAR files infoo
, or vice versa.Subdirectories are not searched recursively. For example,
foo/*
looks for JAR files only infoo
, not infoo/bar
,foo/baz
, etc.The order in which the JAR files in a directory are enumerated in the expanded class path is not specified and may vary from platform to platform and even from moment to moment on the same machine. A well-constructed application should not depend upon any particular order. If a specific order is required then the JAR files can be enumerated explicitly in the class path.
Expansion of wildcards is done early, prior to the invocation of a program's main method, rather than late, during the class-loading process itself. Each element of the input class path containing a wildcard is replaced by the (possibly empty) sequence of elements generated by enumerating the JAR files in the named directory. For example, if the directory
foo
containsa.jar
,b.jar
, andc.jar
, then the class pathfoo/*
is expanded intofoo/a.jar;foo/b.jar;foo/c.jar
, and that string would be the value of the system propertyjava.class.path
.The
CLASSPATH
environment variable is not treated any differently from the-classpath
(or-cp
) command-line option. That is, wildcards are honored in all these cases. However, class path wildcards are not honored in theClass-Path jar-manifest
header.
Note: due to a known bug in java 8, the windows examples must use a backslash preceding entries with a trailing asterisk: https://bugs.openjdk.java.net/browse/JDK-8131329
There's two types of superfluous #include files:
There's 2 ways in my experience that works well to detecting it:
gcc -H or cl.exe /showincludes (resolve problem 2)
In real world, you can export CFLAGS=-H before make, if all the Makefile's not override CFLAGS options. Or as I used, you can create a cc/g++ wrapper to add -H options forcibly to each invoke of $(CC) and $(CXX). and prepend the wrapper's directory to $PATH variable, then your make will all uses you wrapper command instead. Of course your wrapper should invoke the real gcc compiler. This tricks need to change if your Makefile uses gcc directly. instead of $(CC) or $(CXX) or by implied rules.
You can also compile a single file by tweaking with the command line. But if you want to clean headers for the whole project. You can capture all the output by:
make clean
make 2>&1 | tee result.txt
PC-Lint/FlexeLint(resolve problem both 1 and 2)
make sure add the +e766 options, this warning is about: unused header files.
pclint/flint -vf ...
This will cause pclint output included header files, nested header files will be indented appropriately.

Handy way: Using Browser Printing/Preview
we can store session storage like that
store token should be like
localStorage.setItem('user', JSON.stringify({ token: token, username: username }));
Store Session in to sessionStorage
You can store both string and array into session storage
String Ex.
let key = 'title';
let value = 'session';
sessionStorage.setItem(key, value);
Array Ex.
let key = 'user';
let value = [{'name':'shail','email':'[email protected]'}];
value = JSON.stringify(value);
sessionStorage.setItem(key, value);
Get stored session from sessionStorage by key
const session = sessionStorage.getItem('key');
Delete saved session from sessionStorage by key
sessionStorage.removeItem('key');
Delete all saved sessions from sessionStorage
sessionStorage.clear();
Store items in to localStorage
You can store both string and array into location storage
String Ex.
let key = 'title';
let value = 'session';
localStorage.setItem(key, value);
Array Ex.
let key = 'user';
let value = [{'name':'shail','email':'[email protected]'}];
value = JSON.stringify(value);
localStorage.setItem(key, value);
Get stored items from localStorage by key
const item = localStorage.getItem('key');
Delete saved session from localStorage by key
localStorage.removeItem('key');
Delete all saved items from localStorage
localStorage.clear();
I tried a number of methods on this thread, but nothing worked for me. So here is a new solution, which I also found to be very simple:
sqlite
queries necessary to create this database. That's it, now you have your SQLite database.
This one worked for me:
In Activity:
User user;
public User getUser(){ return this.user;}
In Fragment's onCreateView method:
User user = ((MainActivity)getActivity()).getUser();
Replace the MainActivity
with your Activity Name.
In python, not
is a boolean operator which gets the opposite of a value:
>>> myval = 0
>>> nyvalue = not myval
>>> nyvalue
True
>>> myval = 1
>>> nyvalue = not myval
>>> nyvalue
False
And True == 1
and False == 0
(if you need to convert it to an integer, you can use int()
)
For those like me that stumbled here looking for a viable solution to this issue, when the variable might be undefined, the closest i got is:
if 'variablename' in globals() and ((variablename or False) == True):
print('variable exists and it\'s true')
else:
print('variable doesn\'t exist, or it\'s false')
Note that a string is needed when checking in globals, but afterwards the actual variable is used when checking for value.
More on variable existence: How do I check if a variable exists?
Suggest do this in your code-behind before sending down to SQL Server.
int userVal = int.Parse(txtboxname.Text);
Perhaps try to parse and optionally let the user know.
int? userVal;
if (int.TryParse(txtboxname.Text, out userVal)
{
DoSomething(userVal.Value);
}
else
{ MessageBox.Show("Hey, we need an int over here."); }
The exception you note means that you're not including the value in the call to the stored proc. Try setting a debugger breakpoint in your code at the time you call down into the code that builds the call to SQL Server.
Ensure you're actually attaching the parameter to the SqlCommand.
using (SqlConnection conn = new SqlConnection(connString))
{
SqlCommand cmd = new SqlCommand(sql, conn);
cmd.Parameters.Add("@ParamName", SqlDbType.Int);
cmd.Parameters["@ParamName"].Value = newName;
conn.Open();
string someReturn = (string)cmd.ExecuteScalar();
}
Perhaps fire up SQL Profiler on your database to inspect the SQL statement being sent/executed.
I have used the statement below on debian 10
apt-get install iputils-ping
You are calling nextElement twice. Refactor like this:
while(e.hasMoreElements()){
String param = (String) e.nextElement();
System.out.println(param);
}
A class that is declared using the abstract keyword is known as abstract class
.
Abstraction is a process of hiding the data implementation details, and showing only functionality to the user. Abstraction lets you focus on what the object does instead of how it does it.
Main things of abstract class
An abstract class may or may not contain abstract methods.There can be non abstract methods.
An abstract method is a method that is declared without an implementation (without braces, and followed by a semicolon), like this:
ex : abstract void moveTo(double deltaX, double deltaY);
If a class has at least one abstract method then that class must be abstract
Abstract classes may not be instantiated (You are not allowed to create object of Abstract class)
To use an abstract class, you have to inherit it from another class. Provide implementations to all the abstract methods in it.
If you inherit an abstract class, you have to provide implementations to all the abstract methods in it.
Declare abstract class
Specifying abstract
keyword before the class during declaration makes it abstract. Have a look at the code below:
abstract class AbstractDemo{ }
Declare abstract method
Specifying abstract
keyword before the method during declaration makes it abstract. Have a look at the code below,
abstract void moveTo();//no body
Why we need to abstract classes
In an object-oriented drawing application, you can draw circles, rectangles, lines, Bezier curves, and many other graphic objects. These objects all have certain states (for ex -: position, orientation, line color, fill color) and behaviors (for ex -: moveTo, rotate, resize, draw) in common. Some of these states and behaviors are the same for all graphic objects (for ex : fill color, position, and moveTo). Others require different implementation(for ex: resize or draw). All graphic objects must be able to draw or resize themselves, they just differ in how they do it.
This is a perfect situation for an abstract superclass. You can take advantage of the similarities, and declare all the graphic objects to inherit from the same abstract parent object (for ex : GraphicObject
) as shown in the following figure.
First, you declare an abstract class, GraphicObject
, to provide member variables and methods that are wholly shared by all subclasses, such as the current position and the moveTo method. GraphicObject
also declared abstract methods, such as draw or resize, that need to be a implemented by all subclasses but must be implemented in different ways. The GraphicObject
class can look something like this:
abstract class GraphicObject {
void moveTo(int x, int y) {
// Inside this method we have to change the position of the graphic
// object according to x,y
// This is the same in every GraphicObject. Then we can implement here.
}
abstract void draw(); // But every GraphicObject drawing case is
// unique, not common. Then we have to create that
// case inside each class. Then create these
// methods as abstract
abstract void resize();
}
Usage of abstract method in sub classes
Each non abstract subclasses of GraphicObject
, such as Circle
and Rectangle
, must provide implementations for the draw
and resize
methods.
class Circle extends GraphicObject {
void draw() {
//Add to some implementation here
}
void resize() {
//Add to some implementation here
}
}
class Rectangle extends GraphicObject {
void draw() {
//Add to some implementation here
}
void resize() {
//Add to some implementation here
}
}
Inside the main
method you can call all methods like this:
public static void main(String args[]){
GraphicObject c = new Circle();
c.draw();
c.resize();
c.moveTo(4,5);
}
Ways to achieve abstraction in Java
There are two ways to achieve abstraction in java
Abstract class with constructors, data members, methods, etc
abstract class GraphicObject {
GraphicObject (){
System.out.println("GraphicObject is created");
}
void moveTo(int y, int x) {
System.out.println("Change position according to "+ x+ " and " + y);
}
abstract void draw();
}
class Circle extends GraphicObject {
void draw() {
System.out.println("Draw the Circle");
}
}
class TestAbstract {
public static void main(String args[]){
GraphicObject grObj = new Circle ();
grObj.draw();
grObj.moveTo(4,6);
}
}
Output:
GraphicObject is created
Draw the Circle
Change position according to 6 and 4
Remember two rules:
If the class has few abstract methods and few concrete methods,
declare it as an abstract
class.
If the class has only abstract methods, declare it as an interface
.

I had your issue and got it working again (on windows 7).
My setup had actually worked at first. I installed postgres and then set up the system PATH variables with C:\Program Files\PostgreSQL\9.6\bin; C:\Program Files\PostgreSQL\9.6\lib
. The psql keyword in the command line gave no errors.
I deleted the PATH variables above one at a time to test if they were both really needed. Psql continued to work after I deleted the lib path, but stopped working after I deleted the bin path. When I returned bin, it still didn't work, and the same with lib. I closed and reopened the command line between tries, and checked the path. The problem lingered even though the path was identical to how it had been when working. I re-pasted it.
I uninstalled and reinstalled postgres. The problem lingered. It finally worked after I deleted the spaces between the "; C:..." in the paths and re-saved.
Not sure if it was really the spaces that were the culprit. Maybe the environment variables just needed to be altered and refreshed after the install.
I'm also still not sure if both lib and bin paths are needed since there seems to be some kind of lingering memory for old path configurations. I don't want to test it again though.
Fitting an Iframe inside containers will not match the size of the container. It adds about 20px of padding. Currently there is no easy way to fix this. You need javascript (http://css-tricks.com/snippets/jquery/fit-iframe-to-content/)
Negative margins would be an easy solution.

For example in my case I use Symfony 4.4 (PHP).
If you want to update User, you need to insert the User password
encrypted and test with the current Password not encrypted to verify
if it's the same User.
For example :
public function updateUser(Request $req)
{
$entityManager = $this->getDoctrine()->getManager();
$repository = $entityManager->getRepository(User::class);
$user = $repository->find($req->get(id)); /// get User from your DB
if($user == null){
throw $this->createNotFoundException('User don't exist!!', $user);
}
$password_old_encrypted = $user->getPassword();//in your DB is always encrypted.
$passwordToUpdate = $req->get('password'); // not encrypted yet from request.
$passwordToUpdateEncrypted = password_hash($passwordToUpdate , PASSWORD_DEFAULT);
////////////VERIFY IF IT'S THE SAME PASSWORD
$isPass = password_verify($passwordToUpdateEncrypted , $password_old_encrypted );
if($isPass === false){ // failure
throw $this->createNotFoundException('Your password it's not verify', null);
}
return $isPass; //// true!! it's the same password !!!
}
In case someone wants to do this in the programming way! Do the following: Update the color file in your values folder with this.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="transparent">#00ffffff</color> <!--This is the transparency line-->
</resources>
then call the transparency programitically
your_textview.setBackgroundResource(R.color.transparent);
foreach(string s in sList)
{
if(s.equals("ok"))
{
return true;
}
}
return false;
Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:
create table foo (
bar int[] default '{}'
);
select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]
create index on foo using gin (bar); -- allows to use an index in the above query
But as the prior answer suggests, it will be better to normalize properly.
I think that the shortest, fastest and simplest way would be:
SELECT
object_name(object_id) AS [Table],
SUM(row_count) AS [Count]
FROM
sys.dm_db_partition_stats
WHERE
--object_schema_name(object_id) = 'dbo' AND
index_id < 2
GROUP BY
object_id
using alberT and Dan Tao solution:
negative to positive and viceversa
$num = $num <= 0 ? abs($num) : -$num ;
I had this issue when trying to push after a rebase through Visual Studio Code, my issue was solved by just copying the command from the git output window and executing it from the terminal window in Visual Studio Code.
In my case the command was something like:
git push origin NameOfMyBranch:NameOfMyBranch
I know this is old, but just thought I would add my solution just in case someone finds it useful.
I wanted to compare the local naive datetime with an aware datetime from a timeserver. I basically created a new naive datetime object using the aware datetime object. It's a bit of a hack and doesn't look very pretty but gets the job done.
import ntplib
import datetime
from datetime import timezone
def utc_to_local(utc_dt):
return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)
try:
ntpt = ntplib.NTPClient()
response = ntpt.request('pool.ntp.org')
date = utc_to_local(datetime.datetime.utcfromtimestamp(response.tx_time))
sysdate = datetime.datetime.now()
...here comes the fudge...
temp_date = datetime.datetime(int(str(date)[:4]),int(str(date)[5:7]),int(str(date)[8:10]),int(str(date)[11:13]),int(str(date)[14:16]),int(str(date)[17:19]))
dt_delta = temp_date-sysdate
except Exception:

To understand Strong and Weak reference consider below example, suppose we have method named as displayLocalVariable.
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
}
In above method scope of myView variable is limited to displayLocalVariable method, once the method gets finished myView variable which is holding the UIView object will get deallocated from the memory.
Now what if we want to hold the myView variable throughout our view controller's life cycle. For this we can create the property named as usernameView which will have Strong reference to the variable myView(see @property(nonatomic,strong) UIView* usernameView;
and self.usernameView = myView;
in below code), as below,
@interface LoginViewController ()
@property(nonatomic,strong) UIView* usernameView;
@property(nonatomic,weak) UIView* dummyNameView;
- (void)displayLocalVariable;
@end
@implementation LoginViewController
- (void)viewDidLoad
{
[super viewDidLoad];
}
-(void)viewWillAppear:(BOOL)animated
{
[self displayLocalVariable];
}
- (void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.usernameView = myView;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
@end
Now in above code you can see myView has been assigned to self.usernameView and self.usernameView is having a strong reference(as we declared in interface using @property) to myView. Hence myView will not get deallocated from memory till self.usernameView is alive.
Now consider assigning myName to dummyNameView which is a Weak reference, self.dummyNameView = myView;
Unlike Strong reference Weak will hold the myView only till there is Strong reference to myView. See below code to understand Weak reference,
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.dummyNameView = myView;
}
In above code there is Weak reference to myView(i.e. self.dummyNameView is having Weak reference to myView) but there is no Strong reference to myView, hence self.dummyNameView will not be able to hold the myView value.
Now again consider the below code,
-(void)displayLocalVariable
{
UIView* myView = [[UIView alloc] init];
NSLog(@"myView tag is = %ld", myView.tag);
self.usernameView = myView;
self.dummyNameView = myView;
}
In above code self.usernameView has a Strong reference to myView, hence self.dummyNameView will now have a value of myView even after method ends since myView has a Strong reference associated with it.
Now whenever we make a Strong reference to a variable it's retain count get increased by one and the variable will not get deallocated till it's retain count reaches to 0.
Hope this helps.
Using hamishmcn's answer as a template I was able to search for a line in a file that match my regex and replacing it with empty string.
import re
fin = open("in.txt", 'r') # in file
fout = open("out.txt", 'w') # out file
for line in fin:
p = re.compile('[-][0-9]*[.][0-9]*[,]|[-][0-9]*[,]') # pattern
newline = p.sub('',line) # replace matching strings with empty string
print newline
fout.write(newline)
fin.close()
fout.close()
There are two directories that looks like JDK.
C:\Program Files\Java\jdk1.7.0_02
C:\Program Files (x86)\Java\jdk1.7.0_02\
This may be due to both 64 bit and 32 bit JDK installed? What ever may be the case, the java.exe
seen by ant.bat should from the JDK. If the JRE's java.exe
comes first in the path, that will be used to guess the JDK location.
Put 'C:\Program Files (x86)\Java\jdk1.7.0_02\bin' or 'C:\Program Files\Java\jdk1.7.0_02' as the first argument in the path.
Further steps:
You can take output of ant -diagnostics
and look for interesting keys. (assuming Sun/Oracle JDK).
java.class.path
java.library.path
sun.boot.library.path
(in my case tools.jar appears in java.class.path)
From here:
-Xmn : the size of the heap for the young generation
Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor".
And a more "official" source from IBM:
-Xmn
Sets the initial and maximum size of the new (nursery) heap to the specified value when using -Xgcpolicy:gencon. Equivalent to setting both -Xmns and -Xmnx. If you set either -Xmns or -Xmnx, you cannot set -Xmn. If you attempt to set -Xmn with either -Xmns or -Xmnx, the VM will not start, returning an error. By default, -Xmn is selected internally according to your system's capability. You can use the -verbose:sizes option to find out the values that the VM is currently using.
To prevent anything from execution if a condition is met one should use the continue and to get out of the loop if a condition is met one should use the break.
For example in the below mentioned code.
for(int i=0;i<5;i++){
if(i==3){
continue;
}
System.out.println(i);
}
The above code will print the result : 0 1 2 4
NOw consider this code
for(int i=0;i<5;i++){
if(i==3){
break;
}
System.out.println(i);
}
This code will print 0 1 2
That is the basic difference in the continue and break.
There's already a question about this, you could perhaps read it
There's no Clone() method as it exists in Java for example, but you could include a copy constructor in your clases, that's another good approach.
class A
{
private int attr
public int Attr
{
get { return attr; }
set { attr = value }
}
public A()
{
}
public A(A p)
{
this.attr = p.Attr;
}
}
This would be an example, copying the member 'Attr' when building the new object.
On a recent project built using Bootstrap 4, I had tried all of the above methods but nothing worked. My approach was by editing the library CSS using jQuery to get 100% on the table.
// * Select2 4.0.7
$('.select2-multiple').select2({
// theme: 'bootstrap4', //Doesn't work
// width:'100%', //Doesn't work
width: 'resolve'
});
//The Fix
$('.select2-w-100').parent().find('span')
.removeClass('select2-container')
.css("width", "100%")
.css("flex-grow", "1")
.css("box-sizing", "border-box")
.css("display", "inline-block")
.css("margin", "0")

Put the fields that you want to center, right or left according above division.
String path ="AnyDirectory/subFolder/last.htm";
int pos = path.lastIndexOf("/") + 1;
path.substring(pos, path.length()-pos) ;
Now you have the last.htm in the path string.
If you don't want to use a List
, ArrayList
, or other dynamically-sized collection and then convert to an array (that's the method I'd recommend, by the way), then you'll have to allocate the array to its maximum possible size, keep track of how many items you put in it, and then create a new array with just those items in it:
private Update BuildMetaData(MetaData[] nvPairs)
{
Update update = new Update();
InputProperty[] ip = new InputProperty[20]; // how to make this "dynamic"
int i;
for (i = 0; i < nvPairs.Length; i++)
{
if (nvPairs[i] == null) break;
ip[i] = new InputProperty();
ip[i].Name = "udf:" + nvPairs[i].Name;
ip[i].Val = nvPairs[i].Value;
}
if (i < nvPairs.Length)
{
// Create new, smaller, array to hold the items we processed.
update.Items = new InputProperty[i];
Array.Copy(ip, update.Items, i);
}
else
{
update.Items = ip;
}
return update;
}
An alternate method would be to always assign update.Items = ip;
and then resize if necessary:
update.Items = ip;
if (i < nvPairs.Length)
{
Array.Resize(update.Items, i);
}
It's less code, but will likely end up doing the same amount of work (i.e. creating a new array and copying the old items).
You could create a user form:
Here is an excerpt from the Book Deep Learning with TensorFlow
In some cases it is desirable for the process to only allocate a subset of the available memory, or to only grow the memory usage as it is needed by the process. TensorFlow provides two configuration options on the session to control this. The first is the
allow_growth
option, which attempts to allocate only as much GPU memory based on runtime allocations, it starts out allocating very little memory, and as sessions get run and more GPU memory is needed, we extend the GPU memory region needed by the TensorFlow process.
1) Allow growth: (more flexible)
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
session = tf.Session(config=config, ...)
The second method is per_process_gpu_memory_fraction
option, which determines the fraction of the overall amount of memory that each
visible GPU should be allocated. Note: No release of memory needed, it can even worsen memory fragmentation when done.
2) Allocate fixed memory:
To only allocate 40%
of the total memory of each GPU by:
config = tf.ConfigProto()
config.gpu_options.per_process_gpu_memory_fraction = 0.4
session = tf.Session(config=config, ...)
Note: That's only useful though if you truly want to bind the amount of GPU memory available on the TensorFlow process.

As of Express 4, the following code appears to do the trick.
Note that you'll need to install body-parser
using npm
.
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.listen(8888);
app.post('/update', function(req, res) {
console.log(req.body); // the posted data
});
1) You can put your favicon where you want and add this tag to your page head
<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />
although some browsers will try to get the favicon from /favicon.ico by default, so you should use the IgnoreRoute.
2) If a browser makes a request for the favicon in another directory it will get a 404 error wich is fine and if you have the link tag in answer 1 in your master page the browser will get the favicon you want.
Well you could use the <Directory>
tag
for example:
<Directory /inscription>
<Files log.txt>
Order allow,deny
Deny from all
</Files>
</Directory>
Do not use ./
because if you just use /
it looks at the root directory of your site.
For a more detailed example visit http://httpd.apache.org/docs/2.2/sections.html
You can also use the index for the sheet:
xls = pd.ExcelFile('path_to_file.xls')
sheet1 = xls.parse(0)
will give the first worksheet. for the second worksheet:
sheet2 = xls.parse(1)
The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression
after all.
I finally came across this nice template for seeing how to execute uninstall strings:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path |
Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} |
ForEach-Object -process {$apps.Set_Item(
$_.getvalue('UninstallString'),
$_.getvalue('DisplayName'))
}
foreach ($uninstall_string in $apps.GetEnumerator()) {
$uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
& $uninstall_app $uninstall_arg
}
This works for me, namely because $app
is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.
Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe
, so there's that too.
Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.

_route
is not the way to go and never was. It was always meant for debugging purposes according to Fabien who created Symfony. It is unreliable as it will not work with things like forwarding and other direct calls to controllers like partial rendering.
You need to inject your route's name as a parameter in your controller, see the doc here
Also, please never use $request->get('');
if you do not need the flexibility it is way slower than using get on the specific property bag that you need (attributes, query or request) so $request->attributes->get('_route');
in this case.
I am not sure it's possible with an "automatic" variable. You can always declare one for yourself and increment it:
$letters = { 'A', 'B', 'C' }
$letters | % {$counter = 0}{...;$counter++}
Or use a for
loop instead...
for ($counter=0; $counter -lt $letters.Length; $counter++){...}
I found the answer to this problem here
Just do
mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');
@outis's answer is good: concise and correct as regards relations.
However, the situation is slightly more complicated as regards SQL.
Consider the usual suppliers and parts database but implemented in SQL:
SELECT * FROM S NATURAL JOIN SP;
would return a resultset** with columns
SNO, SNAME, STATUS, CITY, PNO, QTY
The join is performed on the column with the same name in both tables, SNO
. Note that the resultset has six columns and only contains one column for SNO
.
Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S
and SP
are required):
SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;
The resultset will have seven columns, including two columns for SNO
. The names of the resultset are what the SQL Standard refers to as "implementation dependent" but could look like this:
SNO, SNAME, STATUS, CITY, SNO, PNO, QTY
or perhaps this
S.SNO, SNAME, STATUS, CITY, SP.SNO, PNO, QTY
In other words, NATURAL JOIN
in SQL can be considered to remove columns with duplicated names from the resultset (but alas will not remove duplicate rows - you must remember to change SELECT
to SELECT DISTINCT
yourself).
** I don't quite know what the result of SELECT * FROM table_expression;
is. I know it is not a relation because, among other reasons, it can have columns with duplicate names or a column with no name. I know it is not a set because, among other reasons, the column order is significant. It's not even a SQL table or SQL table expression. I call it a resultset.
This works for me using the normal wc -l
and sed
to strip any char what is not a number.
wc -l big_file.log | sed -E "s/([a-z\-\_\.]|[[:space:]]*)//g"

For completeness, I'll mention that Oracle 12c does support this feature. Also it's supposedly faster than the triggers approach. For example:
CREATE TABLE foo
(
id NUMBER GENERATED BY DEFAULT AS IDENTITY (
START WITH 1 NOCACHE ORDER ) NOT NULL ,
name VARCHAR2 (50)
)
LOGGING ;
ALTER TABLE foo ADD CONSTRAINT foo_PK PRIMARY KEY ( id ) ;

For me the problem was a failing test. If you are doing test driven development than a failing / not implemented test shouldn't break the build. I still want my project to build.
To solve this I added a configuration to surefire so that it ignores a failing test.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>

This worked for me:

getSupportActionBar().setLogo(R.drawable.ic_logo);
getSupportActionBar().setDisplayShowTitleEnabled(false); //optional
as well as:
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.ic_logo); //also displays wide logo
getSupportActionBar().setDisplayShowTitleEnabled(false); //optional
I updated my Chrome browser to the latest version and the issue was fixed.
The first example demonstrates event delegation. The event handler is bound to an element higher up the DOM tree (in this case, the document
) and will be executed when an event reaches that element having originated on an element matching the selector.
This is possible because most DOM events bubble up the tree from the point of origin. If you click on the #id
element, a click event is generated that will bubble up through all of the ancestor elements (side note: there is actually a phase before this, called the 'capture phase', when the event comes down the tree to the target). You can capture the event on any of those ancestors.
The second example binds the event handler directly to the element. The event will still bubble (unless you prevent that in the handler) but since the handler is bound to the target, you won't see the effects of this process.
By delegating an event handler, you can ensure it is executed for elements that did not exist in the DOM at the time of binding. If your #id
element was created after your second example, your handler would never execute. By binding to an element that you know is definitely in the DOM at the time of execution, you ensure that your handler will actually be attached to something and can be executed as appropriate later on.
I think your problem is that you are not using good OO design for your player and enemies. Create two classes:
public class Player
{
int X;
int Y;
int Width;
int Height;
// Getters and Setters
}
public class Enemy
{
int X;
int Y;
int Width;
int Height;
// Getters and Setters
}
Your Player should have X,Y,Width,and Height variables.
Your enemies should as well.
In your game loop, do something like this (C#):
foreach (Enemy e in EnemyCollection)
{
Rectangle r = new Rectangle(e.X,e.Y,e.Width,e.Height);
Rectangle p = new Rectangle(player.X,player.Y,player.Width,player.Height);
// Assuming there is an intersect method, otherwise just handcompare the values
if (r.Intersects(p))
{
// A Collision!
// we know which enemy (e), so we can call e.DoCollision();
e.DoCollision();
}
}
To speed things up, don't bother checking if the enemies coords are offscreen.
In order to perform chmod, you need to be owner of the file you are trying to modify, or the root user.
In case anybody is interested, I wrote a solution for this using Prototype. In order to get the button to appear correctly, I had to specify extraPlugins: 'ajaxsave'

editor.addCommand( pluginName,

{
new Ajax.Request('ajaxsave.php',

parameters: { filename: 'index.html', editor: editor.getData() },
onFailure: function() { ThrowError("Error: The server has returned an unknown error"); },

I had this issue with Android Studio 3
, the SDK manager somehow didn't include the full tools in platform-tools folder so I had to download it manually from:
https://developer.android.com/studio/releases/platform-tools.html
then extract it to my android/sdk/platform-tools/
folder
1.get all tables and views from information_schema.tables, include those of information_schema and pg_catalog.
select * from information_schema.tables
2.get tables and views belong certain schema
select * from information_schema.tables
where table_schema not in ('information_schema', 'pg_catalog')
3.get tables only(almost \dt)
select * from information_schema.tables
where table_schema not in ('information_schema', 'pg_catalog') and
table_type = 'BASE TABLE'
I take the xml route by wrapping the values into elements (M but anything works):
declare @v nvarchar(max) = '100,201,abcde'
select
a.value('.', 'varchar(max)')
from
(select cast('<M>' + REPLACE(@v, ',', '</M><M>') + '</M>' AS XML) as col) as A
CROSS APPLY A.col.nodes ('/M') AS Split(a)
I used ToString() on a date with mm instead of MM.
Some time ago i created an excel file with supported dimensions

To be honest i lost the idea, but it refers another screen feature as size (not only density)

There's lightweight binary editor, check hexedit. http://www.linux.org/apps/AppId_6968.html. I tried using it for editing ELF binaries in Linux at least.
By using just jQuery, you cannot avoid a server call.
However, to achieve this result, I'm using Downloadify, which lets me save files without having to make another server call. Doing this reduces server load and makes a good user experience.
To get a proper CSV you just have to take out all the unnecessary tags and put a ',' between the data.
Set android:textAllCaps="false". If you are using an appcompat style, make sure textAllCaps comes before the style. Otherwise the style will override it. For example:
android:textAllCaps="false"
style="@style/Base.TextAppearance.AppCompat"
XNA 2.0 requires a minimum of a shader 1.1 card. While old tech, not everyone has one. Some newer laptops (in our experience Toshiba tablets with Intel graphics) have no shader 1.1 support. XNA simply wont run on these machines.
This is a significant issue for us and we have shifted to Tao and OpenGL. Plus with Tao we have bindings for audio & Lua support.
If you are using SQL Server, Use the LEN
(Length) function:
SELECT EmployeeName FROM EmployeeTable WHERE LEN(EmployeeName) > 4
MSDN for it states:
Returns the number of characters of the specified string expression,
excluding trailing blanks.
For oracle/plsql you can use Length()
, mysql also uses Length.
Here is the Oracle documentation:
http://www.techonthenet.com/oracle/functions/length.php
And here is the mySQL Documentation of Length(string)
:
http://dev.mysql.com/doc/refman/5.1/en/string-functions.html#function_length
For PostgreSQL, you can use length(string)
or char_length(string)
. Here is the PostgreSQL documentation:
http://www.postgresql.org/docs/current/static/functions-string.html#FUNCTIONS-STRING-SQL
We are currently using MongoDB in production as the caching layer as well as storage engine for product importing and manipulating product data. We are an eCommerce company managing over two million products (100+ million attributes), spanning 10+ distributors and without MongoDB, this task would be nearing impossible.
In Swift you can do something like this. Following condition will be true every time you reach end of the tableView
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
if indexPath.row+1 == postArray.count {
println("came to last row")
}
}
Easy and simple. You don't need create a new FormData or do an Ajax to send image. You can put dragged files in your input field.
$dropzone.ondrop = function (e) {

e.preventDefault();
this.classList.add('dragover');
};
$dropzone.ondragleave = function (e) {
e.preventDefault();
this.classList.remove('dragover');

I recommend splice
method to remove an object from JSON objects array.
jQuery(json).each(function (index){
if(json[index].FirstName == "Test1"){
json.splice(index,1); // This will remove the object that first name equals to Test1
return false; // This will stop the execution of jQuery each loop.
}
});
I use this because when I use delete
method, I get null
object after I do JSON.stringify(json)
Your font sucks, how should a parser ever be able to read that? Take a calligraphy course.
sentence.sub! 'Robert', 'Joe'
Won't cause an exception if the replaced word isn't in the sentence (the []=
variant will).
The above replaces only the first instance of "Robert".
To replace all instances use gsub
/gsub!
(ie. "global substitution"):
sentence.gsub! 'Robert', 'Joe'
The above will replace all instances of Robert with Joe.
while IFS= read -r line; do echo ${#line}; done < abc.txt
It is POSIX, so it should work everywhere.
Edit: Added -r as suggested by William.
Edit: Beware of Unicode handling. Bash and zsh, with correctly set locale, will show number of codepoints, but dash will show bytes—so you have to check what your shell does. And then there many other possible definitions of length in Unicode anyway, so it depends on what you actually want.
Edit: Prefix with IFS=
to avoid losing leading and trailing spaces.
Use sp_rename
EXEC sp_RENAME 'TableName.OldColumnName' , 'NewColumnName', 'COLUMN'
See: SQL SERVER – How to Rename a Column Name or Table Name
Documentation: sp_rename (Transact-SQL)
For your case it would be:
EXEC sp_RENAME 'table_name.old_name', 'new_name', 'COLUMN'
Remember to use single quotes to enclose your values.
If you are 100% sure that directories and files are ok, have a look at the project location.
There is a limit on the path length of files in the Operating System. Perhaps this limit is being exceded in your project files.
Move the project to a shorter folder (say C:/MyProject) and try again!
This was the problem for me!
There is no issue in the code. I have checked with the same code as you have written with new installation.
Form Code:
<form method="POST" action="/foo" >
@csrf
<input type="text" name="name"/><br/>
<input type="submit" value="Add"/>
</form>

file code:
Route::get('/', function () {

});
The result after submitting the form is:
If you clear your browser cache or try with other browser, I think it will fixed.
user2532030's answer is the correct and most simple answer.
I just want to add, that in the case, where the value of the determining cell is not suitable for a RegEx-match, I found the following syntax to work the same, only with numerical values, relations et.c.:
[Custom formula is]
=$B$2:$B = "Complete"
Range: A2:Z1000
If column 2 of any row (row 2 in script, but the leading $ means, this could be any row) textually equals "Complete", do X for the Range of the entire sheet (excluding header row (i.e. starting from A2 instead of A1)).
But obviously, this method allows also for numerical operations (even though this does not apply for op's question), like:
=$B$2:$B > $C$2:$C
So, do stuff, if the value of col B in any row is higher than col C value.
One last thing: Most likely, this applies only to me, but I was stupid enough to repeatedly forget to choose Custom formula is in the drop-down, leaving it at Text contains. Obviously, this won't float...
You need to use ECHO
. Also, put the quotes around the entire file path if it contains spaces.
One other note, use >
to overwrite a file if it exists or create if it does not exist. Use >>
to append to an existing file or create if it does not exist.
Overwrite the file with a blank line:
ECHO.>"C:\My folder\Myfile.log"
Append a blank line to a file:
ECHO.>>"C:\My folder\Myfile.log"
Append text to a file:
ECHO Some text>>"C:\My folder\Myfile.log"
Append a variable to a file:
ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"
From memory, it looked something like this:
#define RETURN(result) return (result);}
int myfunction1(args) {
int x = 0;
// do something
RETURN(x)
int myfunction2(args) {
int y = 0;
// do something
RETURN(y)
int myfunction3(args) {
int z = 0;
// do something
RETURN(z)
Yes that's right, no closing braces in any of the functions. Syntax highlighting was a mess, so he used vi to edit (not vim, it has syntax coloring!)
He was a Russian programmer who had mostly worked in assembly language. He was fanatical about saving as many bytes as possible because he had previously worked on systems with very limited memory. "It was for satellite. Only very few byte, so we use each byte over for many things." (bit fiddling, reusing machine instruction bytes for their numeric values) When I tried to find out what kinds of satellites, I was only able to get "Orbiting satellite. For making to orbit."
He had two other quirks: A convex mirror mounted above his monitor "For knowing who is watching", and an occasional sudden exit from his chair to do a quick ten pushups. He explained this last one as "Compiler found error in code. This is punishment".

I have follow @Michael's answer and it works.
I do it as UserControl where I can drag and drop like a Controls elements. I use MaterialDesign Theme from Nuget to get the Chevron icon and button ripple effect.

Try win32clipboard from the win32all package (that's probably installed if you're on ActiveState Python).
See sample here: http://code.activestate.com/recipes/474121/
Background:
Actually in getComposer website it clearly states that, install the Composer by using the following curl command,
curl -sS https://getcomposer.org/installer |php
And it certainly does what it's intended to do. And then it says to move the composer.phar to the directory /usr/local/bin/composer and then composer will be available Globally, by using the following command line in terminal!
mv composer.phar /usr/local/bin/composer
Question:
So the problem which leads me to Google over it is when I executed the above line in Mac OS X Terminal, it said that, Permission denied. Like as follows:
mv: rename composer.phar to /usr/local/bin/composer: Permission denied
Answer:
Following link led me to the solution like a charm and I'm thankful to that. The thing I just missed was sudo command before the above stated "Move" command line. Now my Move command is as follows:
sudo mv composer.phar /usr/local/bin/composer
Password:
It directly prompts you to authenticate yourself and see if you are authorized. So if you enter a valid password, then the Moving will be done, and you can just check if composer is globally installed, by using the following line.
composer about
I hope this answer helped you to broaden your view and finally resolve your problem.

white-space: nowrap;
: Will never break text, will keep other defaults
white-space: pre;
: Will never break text, will keep multiple spaces after one another as multiple spaces, will break if explicitly written to break(pressing enter in html etc)
margin: auto;
There are two obvious issues with the set literal syntax:
my_set = {'foo', 'bar', 'baz'}
It's not available before Python 2.7
There's no way to express an empty set using that syntax (using {}
creates an empty dict)
Those may or may not be important to you.
The section of the docs outlining this syntax is here.
instanceof works on instances, i.e. on Objects. Sometimes you want to work directly with classes. In this case you can use the asSubClass method of the Class class. Some examples:
1)
Class o=Object.class;
Class c=Class.forName("javax.swing.JFrame").asSubclass(o);
this will go through smoothly because JFrame is subclass of Object. c will contain a Class object representing the JFrame class.
2)
Class o=JButton.class;
Class c=Class.forName("javax.swing.JFrame").asSubclass(o);
this will launch a java.lang.ClassCastException because JFrame is NOT subclass of JButton. c will not be initialized.
3)
Class o=Serializable.class;
Class c=Class.forName("javax.swing.JFrame").asSubclass(o);
this will go through smoothly because JFrame implements the java.io.Serializable interface. c will contain a Class object representing the JFrame class.
Of course the needed imports have to be included.
I think you should casting variable or use Integer
class by call out method doubleValue()
.
Try $(this).load("/file_name.html");
. This method targets a local file.
You can also target remote files (on another domain) take a look at: http://en.wikipedia.org/wiki/Same_origin_policy
A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.
string result = string.Empty;
using (BinaryReader b = new BinaryReader(file.InputStream))
{
byte[] binData = b.ReadBytes(file.ContentLength);
result = System.Text.Encoding.UTF8.GetString(binData);
}
Try this,
1. If you want to skip a particular iteration, use continue.
2. If you want to break out of the immediate loop use break
3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from
the inner loop, use break with label.
eg:
continue
for(int i=0 ; i<5 ; i++){
if (i==2){
continue;
}
}
eg:
break
for(int i=0 ; i<5 ; i++){
if (i==2){
break;
}
}
eg:
break with label
lab1: for(int j=0 ; j<5 ; j++){
for(int i=0 ; i<5 ; i++){
if (i==2){
break lab1;
}
}
}
The DateTime class takes a string in the constructor. If you prefix the timestamp with a @-character you create a DateTime object with the timestamp. For formating use the 'c' format ... a predefined ISO 8601 compound format.
If could use the DateTime class like this ... set the right timezone or leave it out if you want a UTC time.
$dt = new DateTime('@1333699439');
$dt->setTimezone(new DateTimeZone('America/New_York'));
echo $dt->format('c');
This works for me (styles the first appearance not the dropdown list):
select {
-webkit-appearance: none;
-webkit-border-radius: 0px;
}
Found this really helpful, thank you.
For the Angular 1.X folks out there:
angular.module('myApp').controller('myController', ['$scope', '$document',
function($scope, $document) {
var overflowScrollElement = $document[0].getElementById('your_overflow_scroll_div');
overflowScrollElement[0].scrollTop = overflowScrollElement[0].scrollHeight;
}
]);
Just because the wrapping in jQuery elements versus HTML DOM elements gets a little confusing with angular.
Also for a chat application, I found making this assignment after your chats were loaded to be useful, you also might need to slap on short timeout as well.
As @Brian Riley already said you should either remove 1 column in your select
select countrylanguage.language ,sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language
order by sum(country.population*countrylanguage.percentage) desc ;
or add it to your grouping
select countrylanguage.language, country.code, sum(country.population*countrylanguage.percentage/100)
from countrylanguage
join country on countrylanguage.countrycode = country.code
group by countrylanguage.language, country.code
order by sum(country.population*countrylanguage.percentage) desc ;
Very simple and to be commonly used:
function getDataURI($imagePath) {
$finfo = new finfo(FILEINFO_MIME_TYPE);
$type = $finfo->file($imagePath);
return 'data:'.$type.';base64,'.base64_encode(file_get_contents($imagePath));
}
//Use the above function like below:
echo '<img src="'.getDataURI('./images/my-file.svg').'" alt="">';
echo '<img src="'.getDataURI('./images/my-file.png').'" alt="">';
Note: The Mime-Type of the file will be added automatically (taking help from this PHP documentation).
The problem with your code is :
String show[]= {rs4.getString(1)};
String actuate[]={rs4.getString(2)};
This will create a new array every time your loop (an not append as you might be assuming) and hence in the end you will have only one element per array.
Here is one more way to solve this :
StringBuilder sids = new StringBuilder ();
StringBuilder lids = new StringBuilder ();
while (rs4.next()) {
sids.append(rs4.getString(1)).append(" ");
lids.append(rs4.getString(2)).append(" ");
}
String show[] = sids.toString().split(" ");
String actuate[] = lids.toString().split(" ");
These arrays will have all the required element.
Another alternative is to use a markdown editor like StackEdit. It converts html (or text) into markdown in a WYSIWYG editor. You can create indents, titles, lists in the editor, and it will show you the corresponding text in markdown format. You can then save, publish, share, or download the file. You can access it on their website - no downloads required!
Use "while" statement till user enter a true value and if the input value is not a number or it's a null value skip it and try to ask again and so on. In example I tried to answer truly your question. If we suppose that our age is between 1 and 150 then input value accepted, else it's a wrong value. For terminating program, the user can use 0 key and enter it as a value.
Note: Read comments top of code.
# If your input value is only a number then use "Value.isdigit() == False".
# If you need an input that is a text, you should remove "Value.isdigit() == False".
def Input(Message):
Value = None
while Value == None or Value.isdigit() == False:
try:
Value = str(input(Message)).strip()
except InputError:
Value = None
return Value
# Example:
age = 0
# If we suppose that our age is between 1 and 150 then input value accepted,
# else it's a wrong value.
while age <=0 or age >150:
age = int(Input("Please enter your age: "))
# For terminating program, the user can use 0 key and enter it as an a value.
if age == 0:
print("Terminating ...")
exit(0)
if age >= 18 and age <=150:
print("You are able to vote in the United States!")
else:
print("You are not able to vote in the United States.")
One more solution for mysql 8.0.1 and mariadb 10.2.2 using recursive common table expressions:
with recursive dates as (
select '2010-01-20' as date
union all
select date + interval 1 day from dates where date < '2010-01-24'
)
select * from dates;
Use the SelectedIndex property for the respective employee status in the combo box.
I'm a bit impressed that none of the answers here that used strpos
, strstr
and similar functions mentioned Multibyte String Functions yet (2015-05-08).
Basically, if you're having trouble finding words with characters specific to some languages, such as German, French, Portuguese, Spanish, etc. (e.g.: ä, é, ô, ç, º, ñ), you may want to precede the functions with mb_
. Therefore, the accepted answer would use mb_strpos
or mb_stripos
(for case-insensitive matching) instead:
if (mb_strpos($a,'are') !== false) {
echo 'true';
}
If you cannot guarantee that all your data is 100% in UTF-8, you may want to use the mb_
functions.
A good article to understand why is The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky.
What is happening here is that database route does not accept any url methods.
I would try putting the url methods in the app route just like you have in the entry_page function:
@app.route('/entry', methods=['GET', 'POST'])
def entry_page():
if request.method == 'POST':
date = request.form['date']
title = request.form['blog_title']
post = request.form['blog_main']
post_entry = models.BlogPost(date = date, title = title, post = post)
db.session.add(post_entry)
db.session.commit()
return redirect(url_for('database'))
else:
return render_template('entry.html')
@app.route('/database', methods=['GET', 'POST'])
def database():
query = []
for i in session.query(models.BlogPost):
query.append((i.title, i.post, i.date))
return render_template('database.html', query = query)
It is not possible to limit the number of visible elements in the select dropdown (if you use it as dropdown box and not as list).
But you could use javascript/jQuery to replace this selectbox with something else, which just looks like a dropdown box. Then you can handle the height of dropdown as you want.
jNice would be a jQuery plugin which has such features. But there also exists many alternatives for that.
If you are interested in the fastest execution, you know in advance which value(s) to look for, and your array is 1D, or you are otherwise interested in the result on the flattened array (in which case the input of the function should be np.flatten(arr)
rather than just arr
), then Numba is your friend:
import numba as nb
@nb.jit
def count_nb(arr, value):
result = 0
for x in arr:
if x == value:
result += 1
return result
or, for very large arrays where parallelization may be beneficial:
@nb.jit(parallel=True)
def count_nbp(arr, value):
result = 0
for i in nb.prange(arr.size):
if arr[i] == value:
result += 1
return result
Benchmarking these against np.count_nonzero()
(which also has a problem of creating a temporary array which may be avoided) and np.unique()
-based solution
import numpy as np
def count_np(arr, value):
return np.count_nonzero(arr == value)
import numpy as np
def count_np2(arr, value):
uniques, counts = np.unique(a, return_counts=True)
counter = dict(zip(uniques, counts))
return counter[value] if value in counter else 0
for input generated with:
def gen_input(n, a=0, b=100):
return np.random.randint(a, b, n)
the following plots are obtained (the second row of plots is a zoom on the faster approach):
Showing that Numba-based solution are noticeably faster than the NumPy counterparts, and, for very large inputs, the parallel approach is faster than the naive one.

In cases where you have multiple directives on a single DOM element and where the
order in which they’re applied matters, you can use the priority
property to order their
application. Higher numbers run first. The default priority is 0 if you don’t specify one.
EDIT: after the discussion, here's the complete working solution. The key was to remove the attribute: element.removeAttr("common-things");
, and also element.removeAttr("data-common-things");
(in case users specify data-common-things

Explanation why we have to set terminal: true
and priority: 1000
(a high number):
When the DOM is ready, angular walks the DOM to identify all registered directives and compile the directives one by one based on priority
if these directives are on the same element. We set our custom directive's priority to a high number to ensure that it will be compiled first and with terminal: true
, the other directives will be skipped after this directive is compiled.
When our custom directive is compiled, it will modify the element by adding directives and removing itself and use $compile service to compile all the directives (including those that were skipped).
If we don't set terminal:true
and priority: 1000
, there is a chance that some directives are compiled before our custom directive. And when our custom directive uses $compile to compile the element => compile again the already compiled directives. This will cause unpredictable behavior especially if the directives compiled before our custom directive have already transformed the DOM.
For more information about priority and terminal, check out How to understand the `terminal` of directive?
An example of a directive that also modifies the template is ng-repeat
(priority = 1000), when ng-repeat
is compiled, ng-repeat
make copies of the template element before other directives get applied.
Thanks to @Izhaki's comment, here is the reference to ngRepeat
source code: https://github.com/angular/angular.js/blob/master/src/ng/directive/ngRepeat.js
As scompt.com explained, the query might fail. Use this code the get the error of the query or the correct result:
$username = $_POST['username'];
$password = $_POST['password'];
$result = mysql_query("
SELECT * FROM Users
WHERE UserName LIKE '".mysql_real_escape_string($username)."'
");
if($result)
{
while($row = mysql_fetch_array($result))
{
echo $row['FirstName'];
}
} else {
echo 'Invalid query: ' . mysql_error() . "\n";
echo 'Whole query: ' . $query;
}
See the documentation for mysql_query()
for further information.
The actual error was the single quotes so that the variable $username
was not parsed. But you should really use mysql_real_escape_string($username)
to avoid SQL injections.
Although Google uses BigTable for all their main applications, they also use MySQL for other (perhaps minor) apps.
Have a look at qtlcharts. It allows you to create interactive correlation matrices:
library(qtlcharts)
data(iris)
iris$Species <- NULL
iplotCorr(iris, reorder=TRUE)
It's more impressive when you correlate more variables, like in the package's vignette:
>>> import csv
>>> with open('test.csv', 'wb') as f:
... wtr = csv.writer(f, delimiter= ' ')
... wtr.writerows( [[1, 2], [2, 3], [4, 5]])
...
>>> with open('test.csv', 'r') as f:
... for line in f:
... print line,
...
1 2 <<=== Exactly what you said that you wanted.
2 3
4 5
>>>
To get it so that it can be loaded sensibly by Excel, you need to use a comma (the csv default) as the delimiter, unless you are in a locale (e.g. Europe) where you need a semicolon.
The device pixel ratio is the ratio between physical pixels and logical pixels. For instance, the iPhone 4 and iPhone 4S report a device pixel ratio of 2, because the physical linear resolution is double the logical linear resolution.
The formula is:
Where:
is the physical linear resolution
and:
is the logical linear resolution
Other devices report different device pixel ratios, including non-integer ones. For example, the Nokia Lumia 1020 reports 1.6667, the Samsumg Galaxy S4 reports 3, and the Apple iPhone 6 Plus reports 2.46 (source: dpilove). But this does not change anything in principle, as you should never design for any one specific device.
The CSS "pixel" is not even defined as "one picture element on some screen", but rather as a non-linear angular measurement of viewing angle, which is approximately of an inch at arm's length. Source: CSS Absolute Lengths
This has lots of implications when it comes to web design, such as preparing high-definition image resources and carefully applying different images at different device pixel ratios. You wouldn't want to force a low-end device to download a very high resolution image, only to downscale it locally. You also don't want high-end devices to upscale low resolution images for a blurry user experience.
If you are stuck with bitmap images, to accommodate for many different device pixel ratios, you should use CSS Media Queries to provide different sets of resources for different groups of devices. Combine this with nice tricks like background-size: cover
or explicitly set the background-size
to percentage values.
#element { background-image: url('lores.png'); }
@media only screen and (min-device-pixel-ratio: 2) {
#element { background-image: url('hires.png'); }
}
@media only screen and (min-device-pixel-ratio: 3) {
#element { background-image: url('superhires.png'); }
}
This way, each device type only loads the correct image resource. Also keep in mind that the px
unit in CSS always operates on logical pixels.
As more and more device types appear, it gets trickier to provide all of them with adequate bitmap resources. In CSS, media queries is currently the only way, and in HTML5, the picture element lets you use different sources for different media queries, but the support is still not 100 % since most web developers still have to support IE11 for a while more (source: caniuse).
If you need crisp images for icons, line-art, design elements that are not photos, you need to start thinking about SVG, which scales beautifully to all resolutions.
Many people in the Vim community argue that you should not navigate in Insert mode, that it is not the Vim way. I think this is an incorrect sentiment learned when transitioning from standard editors to Vim.
Vim is most powerful when you use its tools to create atomic, repeatable actions or finds.
It is ok to navigate while in Insert mode if you are fixing a mistake you made in the same Insert session. You should not navigate outside of the range of text you modified.
If you make a mistake while entering text and escape out of Insert mode to fix it you will not be able to repeat the intended action, .
will repeat the correction.
Vim does support many Insert mode navigation keys. Obviously there are the arrow keys, Home, and End, but there are also many other shortcuts. See :h ins-special-keys
.
OCR can be pretty CPU intensive, you might want to reconsider doing it on a smart phone.
That aside, to my knowledge the popular OCR libraries are Aspire and Tesseract. Neither are straight up Java, so you're not going to get a drop-in Android OCR library.
However, Tesseract is open source (GitHub hosted infact); so you can throw some time at porting the subset you need to Java. My understanding is its not insane C++, so depending on how badly you need OCR it might be worth the time.
So short answer: No.
Long answer: if you're willing to work for it.
Update! Complete answer overhaul for new plugin!
The following plugin has been tested in all major browsers. It makes traditional use of userAgent
string to re-equip jQuery.browser
only if you're using jQuery version 1.9 or Greater!
It has the traditional jQuery.browser.msie
type properties as well as a few new ones, including a .mobile
property to help decide if user is on a mobile device.
Note: This is not a suitable replacement for feature testing. If you expect to support a specific feature on a specific device, it's still best to use traditional feature testing

You call tarfile.open with mode='w:gz'
, meaning "Open for gzip compressed writing."
You'll probably want to end the filename (the name
argument to open
) with .tar.gz
, but that doesn't affect compression abilities.
BTW, you usually get better compression with a mode of 'w:bz2'
, just like tar
can usually compress even better with bzip2
than it can compress with gzip
.
These are properties. You would use them like so:
Tom.Title = "Accountant";
string desc = Tom.Description;
But considering they are declared protected
their visibility may be a concern.
stdio is part of the standard C library which, by default, gcc will link against.
The math function implementations are in a separate libm file that is not linked to by default so you have to specify it -lm. By the way, there is no relation between those header files and library files.
git checkout -b <branch-name> <origin/branch_name>
for example in my case:
git branch -a
* master
origin/HEAD
origin/enum-account-number
origin/master
origin/rel_table_play
origin/sugarfield_customer_number_show_c
So to create a new branch based on my enum-account-number branch I do:
git checkout -b enum-account-number origin/enum-account-number
After you hit return the following happens:
Branch enum-account-number set up to track remote branch refs/remotes/origin/enum-account-number.
Switched to a new branch "enum-account-number"
We can summarize by using summarize_at
, summarize_all
and summarize_if
on dplyr 0.7.4
. We can set the multiple columns and functions by using vars
and funs
argument as below code. The left-hand side of funs formula is assigned to suffix of summarized vars. In the dplyr 0.7.4
, summarise_each
(and mutate_each
) is already deprecated, so we cannot use these functions.
options(scipen = 100, dplyr.width = Inf, dplyr.print_max = Inf)
library(dplyr)
packageVersion("dplyr")
# [1] ‘0.7.4’
set.seed(123)
df <- data_frame(
a = sample(1:5, 10, replace=T),
b = sample(1:5, 10, replace=T),
c = sample(1:5, 10, replace=T),
d = sample(1:5, 10, replace=T),
grp = as.character(sample(1:3, 10, replace=T)) # For convenience, specify character type
)
df %>% group_by(grp) %>%
summarise_each(.vars = letters[1:4],
.funs = c(mean="mean"))
# `summarise_each()` is deprecated.
# Use `summarise_all()`, `summarise_at()` or `summarise_if()` instead.
# To map `funs` over a selection of variables, use `summarise_at()`
# Error: Strings must match column names. Unknown columns: mean
You should change to the following code. The following codes all have the same result.
# summarise_at
df %>% group_by(grp) %>%
summarise_at(.vars = letters[1:4],
.funs = c(mean="mean"))
df %>% group_by(grp) %>%
summarise_at(.vars = names(.)[1:4],
.funs = c(mean="mean"))
df %>% group_by(grp) %>%
summarise_at(.vars = vars(a,b,c,d),
.funs = c(mean="mean"))
# summarise_all
df %>% group_by(grp) %>%
summarise_all(.funs = c(mean="mean"))
# summarise_if
df %>% group_by(grp) %>%
summarise_if(.predicate = function(x) is.numeric(x),
.funs = funs(mean="mean"))
# A tibble: 3 x 5
# grp a_mean b_mean c_mean d_mean
# <chr> <dbl> <dbl> <dbl> <dbl>
# 1 1 2.80 3.00 3.6 3.00
# 2 2 4.25 2.75 4.0 3.75
# 3 3 3.00 5.00 1.0 2.00
You can also have multiple functions.
df %>% group_by(grp) %>%
summarise_at(.vars = letters[1:2],
.funs = c(Mean="mean", Sd="sd"))
# A tibble: 3 x 5
# grp a_Mean b_Mean a_Sd b_Sd

You can specify gradients for colours in certain circumstances in CSS3, and of course borders can be set to a colour, so you should be able to use a gradient as a border colour. This would include the option of specifying a transparent colour, which means you should be able to achieve the effect you're after.
However, I've never seen it used, and I don't know how well supported it is by current browsers. You'll certainly need to accept that at least some of your users won't be able to see it.

It turned out that the SecurityContextPersistenceFilter
, which is part of the Spring Security filter chain, always resets my SecurityContext
, which I set calling SecurityContextHolder.getContext().setAuthentication(principal)
(or by using the .principal(principal)
method). This filter sets the SecurityContext
in the SecurityContextHolder
with a SecurityContext
from a SecurityContextRepository
OVERWRITING the one I set earlier. The repository is a HttpSessionSecurityContextRepository
by default. The HttpSessionSecurityContextRepository
inspects the given HttpRequest
and tries to access the corresponding HttpSession
. If it exists, it will try to read the SecurityContext
from the HttpSession
. If this fails, the repository generates an empty SecurityContext
.
Thus, my solution is to pass a HttpSession
along with the request, which holds the SecurityContext
:
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import org.junit.Test;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.context.HttpSessionSecurityContextRepository;
import eu.ubicon.webapp.test.WebappTestEnvironment;
public class Test extends WebappTestEnvironment {
public static class MockSecurityContext implements SecurityContext {
private static final long serialVersionUID = -1386535243513362694L;
private Authentication authentication;
public MockSecurityContext(Authentication authentication) {
this.authentication = authentication;
}
@Override
public Authentication getAuthentication() {

}
@Override
public void setAuthentication(Authentication authentication) {
this.authentication = authentication;
}
}
@Test
public void signedIn() throws Exception {
UsernamePasswordAuthenticationToken principal =
this.getPrincipal("test1");
MockHttpSession session = new MockHttpSession();
session.setAttribute(
HttpSessionSecurityContextRepository.SPRING_SECURITY_CONTEXT_KEY,
new MockSecurityContext(principal));

Java supports closures just fine. It just doesn't support functions, so the syntax you're used to for closures is much more awkward and bulky: you have to wrap everything up in a class with a method. For example,
public Runnable foo(final int x) {
return new Runnable() {
public void run() {
System.out.println(x);
}
};
}
Will return a Runnable object whose run()
method "closes over" the x
passed in, just like in any language that supports first-class functions and closures.
Just setting json

Assertions are generally used primarily as a means of checking the program's expected behavior. It should lead to a crash in most cases, since the programmer's assumptions about the state of the program are false. This is where the debugging aspect of assertions come in. They create a checkpoint that we simply can't ignore if we would like to have correct behavior.
In your case it does data validation on the incoming parameters, though it does not prevent clients from misusing the function in the future. Especially if they are not, (and should not) be included in release builds.
Dumb solution: Connecting them through a named pipe (mkfifo). Then the command can be run second.

The traceback module and sys.exc_info are overkill for tracking down the source of an exception. That's all in the default traceback. So instead of calling exit(1) just re-raise:
try:
assert "birthday cake" == "ice cream cake", "Should've asked for pie"
except AssertionError:
print 'Houston, we have a problem.'
raise
Which gives the following output that includes the offending statement and line number:
Houston, we have a problem.
Traceback (most recent call last):
File "/tmp/poop.py", line 2, in <module>
assert "birthday cake" == "ice cream cake", "Should've asked for pie"
AssertionError: Should've asked for pie
Similarly the logging module makes it easy to log a traceback for any exception (including those which are caught and never re-raised):
import logging
try:
assert False == True
except AssertionError:
logging.error("Nothing is real but I can't quit...", exc_info=True)
Threads do not really have return values. However, if you create a delegate, you can invoke it asynchronously via the BeginInvoke
method. This will execute the method on a thread pool thread. You can get any return value from such as call via EndInvoke
.
Example:
static int GetAnswer() {
return 42;
}
...
Func<int> method = GetAnswer;
var res = method.BeginInvoke(null, null); // provide args as needed

use this:
pil_image = PIL.Image.open('Image.jpg').convert('RGB')
open_cv_image = numpy.array(pil_image)
# Convert RGB to BGR
open_cv_image = open_cv_image[:, :, ::-1].copy()
How do I add a junit 4 dependency correctly?
Assuming you're resolving against a standard Maven (or equivalent) repo:
dependencies {
...
testCompile "junit:junit:4.11" // Or whatever version
}
Run those tests in the folders of tests/model?
You define your test source set the same way:
sourceSets {
...
test {
java {
srcDirs = ["test/model"] // Note @Peter's comment below
}
}
}
Then invoke the tests as:
./gradlew test
EDIT: If you are using JUnit 5 instead, there are more steps to complete, you should follow this tutorial.
You can use setTimeout
or setInterval
.
The difference is - setTimeout triggers your function only once, and then you must set it again. setInterval keeps triggering expression again and again, unless you tell it to stop
This error may occur if input data contain escape character itself. By default escape character is "\" symbol, so if your input text contain "\" character - try to change the default value using ESCAPE option.
I`ve added
initSelection: function (element, callback) {
callback({ id: 1, text: 'Text' });
}
BUT also
.select2('val', []);
at the end.
This solved my issue.
This worked well for me (MySQL 5.5), also solving the problem of a "starting" position.
SELECT
IF(res.nextID, res.nextID, @r) AS nextID
FROM
(SELECT @r := 30) AS vars,
(
SELECT MIN(t1.id + 1) AS nextID
FROM test t1
LEFT JOIN test t2
ON t1.id + 1 = t2.id
WHERE t1.id >= @r
AND t2.id IS NULL
AND EXISTS (
SELECT id
FROM test
WHERE id = @r
)
LIMIT 1
) AS res
LIMIT 1
As mentioned before these types of queries are very slow, at least in MySQL.
Just add overflow:hidden
to the table with border-radius
.
.tablewithradius {
overflow:hidden ;
border-radius: 15px;
}
domContentLoaded: marks the point when both the DOM is ready and there are no stylesheets that are blocking JavaScript execution - meaning we can now (potentially) construct the render tree. Many JavaScript frameworks wait for this event before they start executing their own logic. For this reason the browser captures the EventStart and EventEnd timestamps to allow us to track how long this execution took.
loadEvent: as a final step in every page load the browser fires an “onload” event which can trigger additional application logic.
Assuming I am understanding your question and setup correctly,
If you're trying to use the build number in your script, you have two options:
1) When calling ant, use: ant -Dbuild_parameter=${BUILD_NUMBER}
2) Change your script so that:
<property environment="env" />
<property name="build_parameter" value="${env.BUILD_NUMBER}"/>
It is situational.
The Android documentation suggests that you should use AlarmManager to register an Intent that will fire at the specified time if your application may not be running.
Otherwise, you should use Handler.
Note: The Alarm Manager is intended for cases where you want to have your application code run at a specific time, even if your application is not currently running. For normal timing operations (ticks, timeouts, etc) it is easier and much more efficient to use Handler.
This is the best .htaccess

Use the dict constructor
d1={1:2,3:4}
d2={5:6,7:9}
d3={10:8,13:22}
d4 = reduce(lambda x,y: dict(x, **y), (d1, d2, d3))
As a function
from functools import partial
dict_merge = partial(reduce, lambda a,b: dict(a, **b))
The overhead of creating intermediate dictionaries can be eliminated by using thedict.update()
method:
from functools import reduce
def update(d, other): d.update(other); return d
d4 = reduce(update, (d1, d2, d3), {})
If you need to programmatically and asynchronously load a CSS link:
// https://www.filamentgroup.com/lab/load-css-simpler/
function loadCSS(href, position) {
const link = document.createElement('link');
link.media = 'print';
link.rel = 'stylesheet';
link.href = href;
link.onload = () => { link.media = 'all'; };
position.parentNode.insertBefore(link, position);
}
List<Something> result = new ArrayList<Something>(all);
EnumSet
is a Java Collection, as it implements the Set
interface:
public interface Set<E> extends Collection<E>
So anything you can do with a Collection you can do with an EnumSet
.
You can get list of temp tables by following query :
select left(name, charindex('_',name)-1)
from tempdb..sysobjects
where charindex('_',name) > 0 and
xtype = 'u' and not object_id('tempdb..'+name) is null
Add Runtime Color attribute named "tintColor" from StoryBoard. This is working(for Xcode 8 and above).
if you want unselected color.. you can add unselectedItemTintColor
too.
You will get output from column
value 9 to 26 as you have mentioned OFFSET
as 8
If you ever need to delete all the indexes, this may come in handy:
curl -X DELETE 'http://localhost:9200/_all'
Powershell:
Invoke-WebRequest -method DELETE http://localhost:9200/_all
An img
element is a replaced inline element.
It behaves like an inline element (because it is), but some generalizations about inline elements do not apply to img
elements.
e.g.
Generalization: "Width does not apply to inline elements"
What the spec actually says: "Applies to: all elements but non-replaced inline elements, table rows, and row groups "
Since an image is a replaced inline element, it does apply.
All,
Here a little bit twist with mysql-community-server 5.7 I share some steps, how to reset mysql5.7 root password or set password. it will work centos7 and RHEL7 as well.
step1. 1st stop your databases
service mysqld stop
step2. 2nd modify /etc/my.cnf file add "skip-grant-tables"
vi /etc/my.cnf
[mysqld] skip-grant-tables
step3. 3rd start mysql
service mysqld start
step4. select mysql default database
mysql -u root
mysql>use mysql;
step4. set a new password
mysql> update user set authentication_string=PASSWORD("yourpassword") where User='root'
;
step5 restart mysql database
service mysqld restart
mysql -u root -p
enjoy :)
Assuming your controller's action method is something like this:
public ActionResult AllCategories(int id = 0)
{
return View(db.Categories.Include(p => p.Products).ToList());
}
Modify your models to be something like this:
public class Product
{
[Key]
public int ID { get; set; }
public int CategoryID { get; set; }
//new code
public virtual Category Category { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public string Path { get; set; }
//remove code below
//public virtual ICollection<Category> Categories { get; set; }
}
public class Category
{
[Key]
public int CategoryID { get; set; }
public string Name { get; set; }
//new code
public virtual ICollection<Product> Products{ get; set; }
}
Then your since now the controller takes in a Category as Model (instead of a Product):
foreach (var category in Model)
{
<h3><u>@category.Name</u></h3>
<div>
<ul>
@foreach (var product in Model.Products)
{
// cut for brevity, need to add back more code from original
<li>@product.Title</li>
}
</ul>
</div>
}
UPDATED: Add ToList() to the controller return statement.
A few encoding issues that I had to face couldn't be solved by above solutions. I had to either update my Android Studio or run test cases using following command in the AS terminal.
gradlew clean assembleDebug testDebug
P.S your encoding settings for IDE and project should match.
Hope it helps !
if you want to encode or decode an array from or to JSON you can use these functions
$myJSONString = json_encode($myArray);
$myArray = json_decode($myString);
json_encode will result in a JSON string, built from an (multi-dimensional) array. json_decode will result in an Array, built from a well formed JSON string
with json_decode you can take the results from the API and only output what you want, for example:
echo $myArray['payload']['ign'];
Normally "app" is the root of your application -- have you tried app/path/to/assets/img.png
?
<input name="submitBnt" type="submit" value="like"/>
name is useful when using $_POST
in php and also in javascript as document.getElementByName('submitBnt')
.
Also you can use name as a CS selector like input[name="submitBnt"]
;
Hope this helps
Try ctrl+F5, it will hold your Screen until you press any key. Regards
You can use String.valueOf() for float, double, int, boolean etc.
double d = 0;
float f = 0;
int i = 0;
short i1 = 0;
char c = 0;
boolean bool = false;
char[] chars = {};
Object obj = new Object();
String.valueOf(d);
String.valueOf(i);
String.valueOf(i1);
String.valueOf(f);
String.valueOf(c);
String.valueOf(chars);
String.valueOf(bool);
String.valueOf(obj);
Take a look QRCoder - pure C# open source QR code generator. Can be used in three lines of code
QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(textBoxQRCode.Text, QRCodeGenerator.ECCLevel.Q);
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20);
Even though I'm somewhat late answering the question:
You can now use WebElement.isDisplayed()
to check if an element is visible.
Note:
There are many reasons why an element could be invisible. Selenium tries cover most of them, but there are edge cases where it does not work as expected.
For example, isDisplayed()
does return false
if an element has display: none
or opacity: 0
, but at least in my test, it does not reliably detect if an element is covered by another due to CSS positioning.
As I tussled with this, TryParse in 3.5 does have NumberStyles: The following code should also do the trick without Regex to ignore thousands seperator.
double.TryParse(length, NumberStyles.AllowDecimalPoint,CultureInfo.CurrentUICulture, out lengthD))
Not relevant to the original question asked but confirming that TryParse() indeed is a good option.
