The ArrayList uses the equals method implemented in the class (your case Thing class) to do the equals comparison.
read() is equivalent to recv() with a flags parameter of 0. Other values for the flags parameter change the behaviour of recv(). Similarly, write() is equivalent to send() with flags == 0.
In DJango 3.0 the default value of a BooleanField in model.py is set like this:
class model_name(models.Model):
example_name = models.BooleanField(default=False)
A quick fix to "plot overlap" is to use plt.tight_layout():
for i,var in enumerate(categorical_variables):
plt.title(var)
plt.xticks(rotation=45)
df[var].hist()
plt.subplot(len(categorical_variables)/2, 2, i+1)
plt.tight_layout()
This is for Visual Studio 2019, After trying a lot of suggestions that failed to work (including changing the port number etc) I solved my problem by deleting a file that was generated on my project's root folder called "debug". As soon as this file was deleted everything started working.
Mat img;
img=Mat::zeros(size of image,CV_8UC3);
if you want it to be of an image img1
img=Mat::zeros(img1.size,CV_8UC3);
You have a lot of pointless jQuery in there, but the $compile service is actually super simple in this case:
.directive( 'test', function ( $compile ) {
return {
restrict: 'E',
scope: { text: '@' },
template: '<p ng-click="add()">{{text}}</p>',
controller: function ( $scope, $element ) {
$scope.add = function () {
var el = $compile( "<test text='n'></test>" )( $scope );
$element.parent().append( el );
};
}
};
});
You'll notice I refactored your directive too in order to follow some best practices. Let me know if you have questions about any of those.
The code below can be used for taking a photo and for picking a photo. Just show a dialog with two options and upon selection, use the appropriate code.
To take picture from camera:
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);//zero can be replaced with any action code (called requestCode)
To pick photo from gallery:
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);//one can be replaced with any action code
onActivityResult
code:
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 0:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
case 1:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
imageview.setImageURI(selectedImage);
}
break;
}
}
Finally add this permission in the manifest file:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Building on @P-Lapointe solution, but making it extremely easy, you could use the maximum values from your data using max()
and then you re-use those maximum values to set the legend
xy coordinates. To make sure you don't get beyond the borders, you set up ylim
slightly over the maximum values.
a=c(rnorm(1000))
b=c(rnorm(1000))
par(mfrow=c(1,2))
plot(a,ylim=c(0,max(a)+1))
legend(x=max(a)+0.5,legend="a",pch=1)
plot(a,b,ylim=c(0,max(b)+1),pch=2)
legend(x=max(b)-1.5,y=max(b)+1,legend="b",pch=2)
app.use()
is intended for binding middleware to your application. The path
is a "mount" or "prefix" path and limits the middleware to only apply to any paths requested that begin with it. It can even be used to embed another application:
// subapp.js
var express = require('express');
var app = modules.exports = express();
// ...
// server.js
var express = require('express');
var app = express();
app.use('/subapp', require('./subapp'));
// ...
By specifying /
as a "mount" path, app.use()
will respond to any path that starts with /
, which are all of them and regardless of HTTP verb used:
GET /
PUT /foo
POST /foo/bar
app.get()
, on the other hand, is part of Express' application routing and is intended for matching and handling a specific route when requested with the GET
HTTP verb:
GET /
And, the equivalent routing for your example of app.use()
would actually be:
app.all(/^\/.*/, function (req, res) {
res.send('Hello');
});
(Update: Attempting to better demonstrate the differences.)
The routing methods, including app.get()
, are convenience methods that help you align responses to requests more precisely. They also add in support for features like parameters and next('route')
.
Within each app.get()
is a call to app.use()
, so you can certainly do all of this with app.use()
directly. But, doing so will often require (probably unnecessarily) reimplementing various amounts of boilerplate code.
Examples:
For simple, static routes:
app.get('/', function (req, res) {
// ...
});
vs.
app.use('/', function (req, res, next) {
if (req.method !== 'GET' || req.url !== '/')
return next();
// ...
});
With multiple handlers for the same route:
app.get('/', authorize('ADMIN'), function (req, res) {
// ...
});
vs.
const authorizeAdmin = authorize('ADMIN');
app.use('/', function (req, res, next) {
if (req.method !== 'GET' || req.url !== '/')
return next();
authorizeAdmin(req, res, function (err) {
if (err) return next(err);
// ...
});
});
With parameters:
app.get('/item/:id', function (req, res) {
let id = req.params.id;
// ...
});
vs.
const pathToRegExp = require('path-to-regexp');
function prepareParams(matches, pathKeys, previousParams) {
var params = previousParams || {};
// TODO: support repeating keys...
matches.slice(1).forEach(function (segment, index) {
let { name } = pathKeys[index];
params[name] = segment;
});
return params;
}
const itemIdKeys = [];
const itemIdPattern = pathToRegExp('/item/:id', itemIdKeys);
app.use('/', function (req, res, next) {
if (req.method !== 'GET') return next();
var urlMatch = itemIdPattern.exec(req.url);
if (!urlMatch) return next();
if (itemIdKeys && itemIdKeys.length)
req.params = prepareParams(urlMatch, itemIdKeys, req.params);
let id = req.params.id;
// ...
});
Note: Express' implementation of these features are contained in its
Router
,Layer
, andRoute
.
The following, taken from here, was not mentioned here:
If the Oracle Client is 32 bit, it will contain a "lib" folder; but if it is a 64 bit Oracle Client it will have both "lib" and "lib32" folders.
Also, starting in Oracle 11.2.0.1, the client version for 64-bit and the Oracle client for 32-bit are shipped separately, and there is an $ORACLE_HOME/lib64 directory.
$ORACLE_HOME/lib/ ==> 32 bit $ORACLE_HOME/lib64 ==> 64 bit
Or
$ORACLE_HOME/lib/ ==> 64 bit $ORACLE_HOME/lib32 ==> 32 bit
For the case: "This has not been pushed, only committed." - if you use IntelliJ (or another JetBrains IDE) and you haven't pushed changes yet you can do next.
Done.
This will "uncommit" your changes and return your git status to the point before your last local commit. You will not lose any changes you made.
df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])
type(df.<column name>)
example: if you want to convert day which is initially a string to a Timestamp in Pandas
df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])
type(df.day)
The output will be pandas.tslib.Timestamp
We often run into this where we want to include a the index value and first and last indicators in a list without creating a new object. This allows you to know the position of the item in your list, enumeration, etc. without having to modify the existing class and then knowing whether you're at the first item in the list or the last.
foreach (Item item in this.Items
.Select((x, i) => {
x.ListIndex = i;
x.IsFirst = i == 0;
x.IsLast = i == this.Items.Count-1;
return x;
}))
You can simply extend any class by using:
public abstract class IteratorExtender {
public int ListIndex { get; set; }
public bool IsFirst { get; set; }
public bool IsLast { get; set; }
}
public class Item : IteratorExtender {}
Have you tried to cast it to a date, with <mydatetime>::date
?
I was having a similar issue with a property being null or undefined.

It is a kind of an interface naming convention which matches with functional programming
//Runnable

}
//Consumer - consumes a value/values, throws exception
interface Consumer1<T> {
void accept(T t) throws Exception;

//Callable - return result, throws exception
interface Callable<R> {
R call() throws Exception;
}
//Supplier - returns result, throws exception
interface Supplier<R> {

}
//Predicate - consumes a value/values, returns true or false, throws exception
interface Predicate1<T> {
boolean test(T t) throws Exception;
}
//Function - consumes a value/values, returns result, throws exception
public interface Function1<T, R> {

Illegal offset type errors occur when you attempt to access an array index using an object or an array as the index key.
Example:
$x = new stdClass();
$arr = array();
echo $arr[$x];
//illegal offset type
Your $xml
array contains an object or array at $xml->entry[$i]->source
for some value of $i
, and when you try to use that as an index key for $s
, you get that warning. You'll have to make sure $xml
contains what you want it to and that you're accessing it correctly.
Something like this - for each line read into string variable a
:
>>> a = "123,456"
>>> b = a.split(",")
>>> b
['123', '456']
>>> c = [int(e) for e in b]
>>> c
[123, 456]
>>> x, y = c
>>> x
123
>>> y
456
Now you can do what is necessary with x
and y
as assigned, which are integers.
int Age = new DateTime((DateTime.Now - BirthDateTime).Ticks).Year;
To calculate the elapsed years (age), the result will be minus one.
var timeSpan = DateTime.Now - birthDateTime;
int age = new DateTime(timeSpan.Ticks).Year - 1;
Pythonic
X = X[:, :, None]
which is equivalent to
X = X[:, :, numpy.newaxis]
and
X = numpy.expand_dims(X, axis=-1)
But as you are explicitly asking about stacking images,
I would recommend going for stacking the list
of images np.stack([X1, X2, X3])
that you may have collected in a loop.
If you do not like the order of the dimensions you can rearrange with np.transpose()
This is not a memory problem even though the exception name highly suggests so, but an operating system resource problem. You are running out of native threads, i.e. how many threads the operating system will allow your JVM to use.
This is an uncommon problem, because you rarely need that many. Do you have a lot of unconditional thread spawning where the threads should but doesn't finish?
You might consider rewriting into using Callable/Runnables under the control of an Executor if at all possible. There are plenty of standard executors with various behavior which your code can easily control.
(There are many reasons why the number of threads is limited, but they vary from operating system to operating system)
No, they're not the same. Aside from the escaping on the client-side that it provides, a prepared statement is compiled on the server-side once, and then can be passed different parameters at each execution. Which means you can do:
$sth = $db->prepare("SELECT * FROM table WHERE foo = ?");
$sth->execute(array(1));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);
$sth->execute(array(2));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);
They generally will give you a performance improvement, although not noticeable on a small scale. Read more on prepared statements (MySQL version).
You can use the method SelectTab
.
There are 3 versions:
public void SelectTab(int index);
public void SelectTab(string tabPageName);
public void SelectTab(TabPage tabPage);
IF NOT EXISTS (SELECT 1

JOIN sysobjects so
ON sc.id = so.id

END

Which, not only is ugly and slow
I'd dispute both.
A regex or other string parsing method would be uglier and slower.
I'm not sure that anything much could be faster than the above. It calls the function and returns. Try/Catch doesn't introduce much overhead because the most common exception is caught without an extensive search of stack frames.
The issue is that any numeric conversion function has two kinds of results
C (as an example) hacks around this a number of ways. Python lays it out clearly and explicitly.

Landed on this page for looking for the fastest way to remove the extension from a number file names from a glob()
result.
So I did some very rudimentary benchmark tests and found this was the quickest method. It was less than half the time of preg_replace()
:
$result = substr($fileName,0,-4);
Now I know that all of the files in my glob()
have a .zip
extension, so I could do this.
If the file extension is unknown with an unknown length, the following method will work and is still about 20% faster that preg_replace()
. That is, so long as there is an extension.
$result = substr($fileName,0,strrpos($fileName,'.'));
The basic benchmark test code and the results:
$start = microtime(true);
$loop = 10000000;
$fileName = 'a.LONG-filename_forTest.zip';
$result;
// 1.82sec preg_replace() unknown ext
//do {
// $result = preg_replace('/\\.[^.\\s]{3,4}$/','',$fileName);
//} while(--$loop);
// 1.7sec preg_replace() known ext
//do {
// $result = preg_replace('/.zip$/','',$fileName);
//} while(--$loop);
// 4.57sec! - pathinfo
//do {
// $result = pathinfo($fileName,PATHINFO_FILENAME);
//} while(--$loop);
// 2.43sec explode and implode
//do {
// $result = implode('.',explode('.',$fileName,-1));
//} while(--$loop);
// 3.74sec basename, known ext
//do {
// $result = basename($fileName,'.zip');
//} while(--$loop);
// 1.45sec strpos unknown ext
//do {
// $result = substr($fileName,0,strrpos($fileName,'.'));
//} while(--$loop);
// 0.73sec strpos - known ext length
do {
$result = substr($fileName,0,-4);
} while(--$loop);
var_dump($fileName);
var_dump($result);
echo 'Time:['.(microtime(true) - $start).']';
exit;

You could use x ** (1. / 3)
to compute the (floating-point) cube root of x
.
The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:
def is_perfect_cube(x):
x = abs(x)
return int(round(x ** (1. / 3))) ** 3 == x
print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
# handles this correctly
This takes the cube root of x
, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x
.
The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).
If you simply need to view the table and run queries on it you can use this third party sdf viewer. It is a lightweight viewer that has all the basic functionalities and is ready to use after install.

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr
variable at compile time, knowing that the difference between constexpr
and static constexpr
is that to use static constexpr
you ensure the variable is initialized only once.
Following code demonstrates how constexpr
variable is initialized multiple times (with same value though), while static constexpr
is surely initialized only once.
In addition the code compares the advantage of constexpr
against const
in combination with static
.
#include <iostream>
#include <string>
#include <cassert>
#include <sstream>
const short const_short = 0;
constexpr short constexpr_short = 0;
// print only last 3 address value numbers
const short addr_offset = 3;
// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
// determine initial size of strings
std::string title = "value \\ address of ";
const size_t ref_size = ref_name.size();
const size_t title_size = title.size();
assert(title_size > ref_size);
// create title (resize)
title.append(ref_name);
title.append(" is ");
title.append(title_size - ref_size, ' ');
// extract last 'offset' values from address
std::stringstream addr;
addr << param;
const std::string addr_str = addr.str();
const size_t addr_size = addr_str.size();
assert(addr_size - offset > 0);
// print title / ref value / address at offset
std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}
// here we test initialization of const variable (runtime)

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{

print_properties("static const", &static_var, addr_offset);
if (counter)

}
// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
constexpr short constexpr_var = constexpr_short;
print_properties("constexpr", &constexpr_var, addr_offset);
if (counter)
constexpr_value(counter - 1);
}
// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
static constexpr short static_constexpr_var = constexpr_short;
print_properties("static constexpr", &static_constexpr_var, addr_offset);
if (counter)
static_constexpr_value(counter - 1);
}
// final test call this method from main()
void test_static_const()
{
constexpr short counter = 2;
const_value(counter);
std::cout << std::endl;
static_value(counter);
std::cout << std::endl;
static_const_value(counter);
std::cout << std::endl;
constexpr_value(counter);
std::cout << std::endl;
static_constexpr_value(counter);
std::cout << std::endl;
}
Possible program output:
value \ address of const is 1 564
value \ address of const is 2 3D4
value \ address of const is 3 244
value \ address of static is 1 C58
value \ address of static is 1 C58
value \ address of static is 1 C58
value \ address of static const is 1 C64
value \ address of static const is 1 C64
value \ address of static const is 1 C64
value \ address of constexpr is 0 564
value \ address of constexpr is 0 3D4
value \ address of constexpr is 0 244
value \ address of static constexpr is 0 EA0
value \ address of static constexpr is 0 EA0
value \ address of static constexpr is 0 EA0
As you can see yourself constexpr
is initilized multiple times (address is not the same) while static
keyword ensures that initialization is performed only once.

I forgot that I had already an unused labs
branch. Deleting it solved my problem:
git branch -d labs
git checkout -b labs/feature
Explanation:
Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs
and labs/feature
can't exists both at the same time.
The reason: Branches are stored in the file system and there you also can't have a file labs
and a directory labs
at the same level.
Be a bit wary of any solution that doesn't involve re-creating the PivotTable from scratch. It is possible for your pivot fields' option names to get out of sync with the values they present to the database.
For example, in one workbook I'm dealing with involving demographic data, if you try to select the "20-24" age band option, Excel actually presents you with the figures for ages 25-29. It doesn't tell you it's doing this, of course.
See below for a programmatic (VBA) approach to the problem that solves this issue among others. I think it's fairly complete/robust, but I don't use PivotTables much so would appreciate feedback.

Looks like you forgot the mode parameter when calling open
, try w
:
file = open("copy.txt", "w")
file.write("Your text goes here")
file.close()
The default value is r
and will fail if the file does not exist
'r' open for reading (default)
'w' open for writing, truncating the file first
Other interesting options are
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
See Doc for Python2.7 or Python3.6
-- EDIT --
As stated by chepner in the comment below, it is better practice to do it with a with
statement (it guarantees that the file will be closed)
with open("copy.txt", "w") as file:
file.write("Your text goes here")
For me, it worked as given below:
<div ng-repeat="product in products | filter: { color: 'red'||'blue' }">
<div ng-repeat="product in products | filter: { color: 'red'} | filter: { color:'blue' }">
This example here is only applicable to pure blittable types, e.g., types that can be memcpy'd directly in C.
Example - well known 64-bit struct
[StructLayout(LayoutKind.Sequential)]
public struct Voxel
{
public ushort m_id;
public byte m_red, m_green, m_blue, m_alpha, m_matid, m_custom;
}
Defined exactly like this, the struct will be automatically packed as 64-bit.
Now we can create volume of voxels:
Voxel[,,] voxels = new Voxel[16,16,16];
And save them all to a byte array:
int size = voxels.Length * 8; // Well known size: 64 bits
byte[] saved = new byte[size];
GCHandle h = GCHandle.Alloc(voxels, GCHandleType.Pinned);
Marshal.Copy(h.AddrOfPinnedObject(), saved, 0, size);
h.Free();
// now feel free to save 'saved' to a File / memory stream.
However, since the OP wants to know how to convert the struct itself, our Voxel struct can have following method ToBytes
:
byte[] bytes = new byte[8]; // Well known size: 64 bits
GCHandle h = GCHandle.Alloc(this, GCHandleType.Pinned);
Marshal.Copy(hh.AddrOfPinnedObject(), bytes, 0, 8);
h.Free();

Something I completely missed: the non-wrapping behaviour of <pre>
can be controlled with CSS. So this gives the exact result I was looking for:
code { _x000D_
background: hsl(220, 80%, 90%); _x000D_
}_x000D_
_x000D_
pre {_x000D_
white-space: pre-wrap;_x000D_
background: hsl(30,80%,90%);_x000D_
}
_x000D_
Here's an example demonstrating the <code><code></code> tag._x000D_
_x000D_
<pre>_x000D_
Here's a very long pre-formatted formatted using the <pre> tag. Notice how it wraps? It goes on and on and on and on and on and on and on and on and on and on..._x000D_
</pre>
_x000D_
You must have seen some application that run from the commandline and let you to pass them arguments. If you write one such app in C#, the array args
serves as the collection of the said arguments.
This how you process them:
static void Main(string[] args) {
foreach (string arg in args) {
//Do something with each argument
}
}
I did it that way and I like it better, but it can be optimized, right?
// Obtengo los botones y la caja de contenido
var home = document.getElementById("home");
var about = document.getElementById("about");
var service = document.getElementById("service");
var contact = document.getElementById("contact");
var content = document.querySelector("section");
function botonPress(e){
console.log(e.getAttribute("id"));
var screen = e.getAttribute("id");
switch(screen){
case "home":
// cambiar fondo
content.style.backgroundColor = 'black';
break;
case "about":
// cambiar fondo
content.style.backgroundColor = 'blue';
break;
case "service":
// cambiar fondo
content.style.backgroundColor = 'green';
break;
case "contact":
// cambiar fondo
content.style.backgroundColor = 'red';
break;
}
}
var mouseX;
var mouseY;
$(document).mousemove( function(e) {
mouseX = e.pageX;
mouseY = e.pageY;
});
$(".classForHoverEffect").mouseover(function(){
$('#DivToShow').css({'top':mouseY,'left':mouseX}).fadeIn('slow');
});
the function above will make the DIV appear over the link wherever that may be on the page. It will fade in slowly when the link is hovered. You could also use .hover() instead. From there the DIV will stay, so if you would like the DIV to disappear when the mouse moves away, then,
$(".classForHoverEffect").mouseout(function(){
$('#DivToShow').fadeOut('slow');
});
If you DIV is already positioned, you can simply use
$('.classForHoverEffect').hover(function(){
$('#DivToShow').fadeIn('slow');
});
Also, keep in mind, your DIV style needs to be set to display:none;
in order for it to fadeIn or show.
No, it is not a bug. It is a result of how the ParameterizedTypeReference
hack works.
If you look at its implementation, it uses Class#getGenericSuperclass()
which states
Returns the Type representing the direct superclass of the entity (class, interface, primitive type or void) represented by this Class.
If the superclass is a parameterized type, the
Type
object returned must accurately reflect the actual type parameters used in the source code.
So, if you use
new ParameterizedTypeReference<ResponseWrapper<MyClass>>() {}
it will accurately return a Type
for ResponseWrapper<MyClass>
.
If you use
new ParameterizedTypeReference<ResponseWrapper<T>>() {}
it will accurately return a Type
for ResponseWrapper<T>
because that is how it appears in the source code.
When Spring sees T
, which is actually a TypeVariable
object, it doesn't know the type to use, so it uses its default.
You cannot use ParameterizedTypeReference
the way you are proposing, making it generic in the sense of accepting any type. Consider writing a Map
with key Class
mapped to a predefined ParameterizedTypeReference
for that class.
You can subclass ParameterizedTypeReference
and override its getType
method to return an appropriately created ParameterizedType
, as suggested by IonSpin.
How are you setting up the SqlParameter
? You should set the SqlDbType
property to SqlDbType.DateTime
and then pass the DateTime
directly to the parameter (do NOT convert to a string, you are asking for a bunch of problems then).
You should be able to get the value into the DB. If not, here is a very simple example of how to do it:
static void Main(string[] args)
{
// Create the connection.
using (SqlConnection connection = new SqlConnection(@"Data Source=..."))
{
// Open the connection.
connection.Open();
// Create the command.
using (SqlCommand command = new SqlCommand("xsp_Test", connection))
{
// Set the command type.
command.CommandType = System.Data.CommandType.StoredProcedure;
// Add the parameter.
SqlParameter parameter = command.Parameters.Add("@dt",
System.Data.SqlDbType.DateTime);
// Set the value.
parameter.Value = DateTime.Now;
// Make the call.
command.ExecuteNonQuery();
}
}
}
I think part of the issue here is that you are worried that the fact that the time is in UTC is not being conveyed to SQL Server. To that end, you shouldn't, because SQL Server doesn't know that a particular time is in a particular locale/time zone.
If you want to store the UTC value, then convert it to UTC before passing it to SQL Server (unless your server has the same time zone as the client code generating the DateTime
, and even then, that's a risk, IMO). SQL Server will store this value and when you get it back, if you want to display it in local time, you have to do it yourself (which the DateTime
struct will easily do).
All that being said, if you perform the conversion and then pass the converted UTC date (the date that is obtained by calling the ToUniversalTime
method, not by converting to a string) to the stored procedure.
And when you get the value back, call the ToLocalTime
method to get the time in the local time zone.
Delete .vs/Config folder => work for me
We got the same issue recently. We found out that the code is looking for the connection string named "LocalSqlServer" in the machine.confg file. We added this line and it is working fine.
For td elements line-height will successfully allow you to resize the border-height as SPrince mentioned.
For other elements such as list items, you can control the border height with line-height and the height of the actual element with margin-top and margin-bottom.
Here is a working example of both: http://jsfiddle.net/byronj/gLcqu6mg/
An example with list items:
li {
list-style: none;
padding: 0 10px;
display: inline-block;
border-right: 1px solid #000;
line-height: 5px;
margin: 20px 0;
}
<ul>
<li>cats</li>
<li>dogs</li>
<li>birds</li>
<li>swine!</li>
</ul>
What about:
#region Using Statements
using System;
using System.Xml;
#endregion
class Program {
static void Main( string[ ] args ) {
XmlDocument doc = new XmlDocument( );
//(1) the xml declaration is recommended, but not mandatory
XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
XmlElement root = doc.DocumentElement;
doc.InsertBefore( xmlDeclaration, root );
//(2) string.Empty makes cleaner code
XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
doc.AppendChild( element1 );
XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
element1.AppendChild( element2 );
XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
XmlText text1 = doc.CreateTextNode( "text" );
element3.AppendChild( text1 );
element2.AppendChild( element3 );
XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
XmlText text2 = doc.CreateTextNode( "other text" );
element4.AppendChild( text2 );
element2.AppendChild( element4 );
doc.Save( "D:\\document.xml" );
}
}
(1) Does a valid XML file require an xml declaration?
(2) What is the difference between String.Empty and “” (empty string)?
The result is:
<?xml version="1.0" encoding="UTF-8"?>
<body>
<level1>
<level2>text</level2>
<level2>other text</level2>
</level1>
</body>
But I recommend you to use LINQ to XML which is simpler and more readable like here:
#region Using Statements
using System;
using System.Xml.Linq;
#endregion
class Program {
static void Main( string[ ] args ) {
XDocument doc = new XDocument( new XElement( "body",
new XElement( "level1",
new XElement( "level2", "text" ),
new XElement( "level2", "other text" ) ) ) );
doc.Save( "D:\\document.xml" );
}
}
This one seems more pythonic to me:
>>> def clip(val, min_, max_):
... return min_ if val < min_ else max_ if val > max_ else val
A few tests:
>>> clip(5, 2, 7)
5
>>> clip(1, 2, 7)
2
>>> clip(8, 2, 7)
7
Try __weak
if you get any warning regarding retain cycle else use __block
Person *strongPerson = [Person new];
__weak Person *weakPerson = person;
Now you can refer weakPerson
object inside block.
The syntax (<<<
) and the command used (echo
) is wrong.
Correct would be:
#!/bin/bash
kernel="2.6.39"
distro="xyz"
cat >/etc/myconfig.conf <<EOL
line 1, ${kernel}
line 2,
line 3, ${distro}
line 4 line
...
EOL
cat /etc/myconfig.conf
This construction is referred to as a Here Document and can be found in the Bash man pages under man --pager='less -p "\s*Here Documents"' bash
.
It may not be the Pythonic way, but I generally use a list with the join function for writing a long string, like SQL queries:
query = " ".join([
'SELECT * FROM "TableName"',
'WHERE "SomeColumn1"=VALUE',
'ORDER BY "SomeColumn2"',
'LIMIT 5;'
])
FWIW, you can pass a table name to useful system SP's like this, should you wish to explore a database that way :
DECLARE @Table sysname; SET @Table = 'TableName';
EXEC sp_fkeys @Table;
EXEC sp_help @Table;

As zserge's comment suggested,
Timber is very nice, but if you already have an existing project - you may try github.com/zserge/log . It's a drop-in replacement for android.util.Log and has most of the the features that Timber has and even more.
his log library provides simple enable/disable log printing switch as below.
In addition, it only requires to change import
lines, and nothing needs to change for Log.d(...);
statement.

Log.usePrinter(Log.ANDROID, false); // from now on Log.d etc do nothing and is likely to be optimized with JIT
For MongoDB 3.6 and newer:
The $expr
operator allows the use of aggregation expressions within the query language, thus you can leverage the use of $strLenCP
operator to check the length of the string as follows:
db.usercollection.find({
"name": { "$exists": true },
"$expr": { "$gt": [ { "$strLenCP": "$name" }, 40 ] }
})
For MongoDB 3.4 and newer:
You can also use the aggregation framework with the $redact
pipeline operator that allows you to proccess the logical condition with the $cond
operator and uses the special operations $$KEEP
to "keep" the document where the logical condition is true or $$PRUNE
to "remove" the document where the condition was false.
This operation is similar to having a $project
pipeline that selects the fields in the collection and creates a new field that holds the result from the logical condition query and then a subsequent $match
, except that $redact
uses a single pipeline stage which is more efficient.
As for the logical condition, there are String Aggregation Operators that you can use $strLenCP
operator to check the length of the string. If the length is $gt
a specified value, then this is a true match and the document is "kept". Otherwise it is "pruned" and discarded.
Consider running the following aggregate operation which demonstrates the above concept:
db.usercollection.aggregate([
{ "$match": { "name": { "$exists": true } } },
{
"$redact": {
"$cond": [
{ "$gt": [ { "$strLenCP": "$name" }, 40] },
"$$KEEP",
"$$PRUNE"
]
}
},
{ "$limit": 2 }
])
If using $where
, try your query without the enclosing brackets:
db.usercollection.find({$where: "this.name.length > 40"}).limit(2);
A better query would be to to check for the field's existence and then check the length:
db.usercollection.find({name: {$type: 2}, $where: "this.name.length > 40"}).limit(2);
or:
db.usercollection.find({name: {$exists: true}, $where: "this.name.length >
40"}).limit(2);
MongoDB evaluates non-$where
query operations before $where
expressions and non-$where
query statements may use an index. A much better performance is to store the length of the string as another field and then you can index or search on it; applying $where
will be much slower compared to that. It's recommended to use JavaScript expressions and the $where
operator as a last resort when you can't structure the data in any other way, or when you are dealing with a
small subset of data.
A different and faster approach that avoids the use of the $where
operator is the $regex
operator. Consider the following pattern which searches for
db.usercollection.find({"name": {"$type": 2, "$regex": /^.{41,}$/}}).limit(2);
Note - From the docs:
If an index exists for the field, then MongoDB matches the regular expression against the values in the index, which can be faster than a collection scan. Further optimization can occur if the regular expression is a “prefix expression”, which means that all potential matches start with the same string. This allows MongoDB to construct a “range” from that prefix and only match against those values from the index that fall within that range.
A regular expression is a “prefix expression” if it starts with a caret
(^)
or a left anchor(\A)
, followed by a string of simple symbols. For example, the regex/^abc.*/
will be optimized by matching only against the values from the index that start withabc
.Additionally, while
/^a/, /^a.*/,
and/^a.*$/
match equivalent strings, they have different performance characteristics. All of these expressions use an index if an appropriate index exists; however,/^a.*/
, and/^a.*$/
are slower./^a/
can stop scanning after matching the prefix.

youtube-dl is a command-line program to download videos from YouTube.com and a few more sites. It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is not platform specific. It should work on your Unix box, on Windows or on macOS. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.
$ youtube-dl [OPTIONS] URL [URL...]
--playlist-start NUMBER Playlist video to start at (default is 1) --playlist-end NUMBER Playlist video to end at (default is last) --playlist-items ITEM_SPEC Playlist video items to download. Specify indices of the videos in the playlist separated by commas like: "--playlist-items 1,2,5,8" if you want to download videos indexed 1, 2, 5, 8 in the playlist. You can specify range: "--playlist-items 1-3,7,10-13", it will download the videos at index 1, 2, 3, 7, 10, 11, 12 and 13.
The problem with global variables is that since every function has access to these, it becomes increasingly hard to figure out which functions actually read and write these variables.
To understand how the application works, you pretty much have to take into account every function which modifies the global state. That can be done, but as the application grows it will get harder to the point of being virtually impossible (or at least a complete waste of time).
If you don't rely on global variables, you can pass state around between different functions as needed. That way you stand a much better chance of understanding what each function does, as you don't need to take the global state into account.
If you don't want to lose the ratio of your image, then don't bother with height:300px;
and just use width:100%;
.
If the image is too large, then you will have to crop it using an image editor.
If you are concerned about memory footprint, the Python standard library contains the array module; these arrays contain elements of the same type.
To specify a variable is an array of objects:
$needles = getAllNeedles();
/* @var $needles Needle[] */
$needles[1]->... //codehinting works
This works in Netbeans 7.2 (I'm using it)
Works also with:
$needles = getAllNeedles();
/* @var $needles Needle[] */
foreach ($needles as $needle) {
$needle->... //codehinting works
}
Therefore use of declaration inside the foreach
is not necessary.

There is much more to it than you think. Consider the defaults to be static (=constant reference pointing to one object) and stored somewhere in the definition; evaluated at method definition time; as part of the class, not the instance. As they are constant, they cannot depend on self
.
Here is an example. It is counterintuitive, but actually makes perfect sense:
def add(item, s=[]):
s.append(item)
print len(s)
add(1) # 1
add(1) # 2
add(1, []) # 1
add(1, []) # 1
add(1) # 3
This will print 1 2 1 1 3
.
Because it works the same way as
default_s=[]
def add(item, s=default_s):
s.append(item)
Obviously, if you modify default_s
, it retains these modifications.
There are various workarounds, including
def add(item, s=None):
if not s: s = []
s.append(item)
or you could do this:
def add(self, item, s=None):
if not s: s = self.makeDefaultS()
s.append(item)
Then the method makeDefaultS
will have access to self
.
Another variation:
import types
def add(item, s=lambda self:[]):
if isinstance(s, types.FunctionType): s = s("example")
s.append(item)
here the default value of s
is a factory function.
You can combine all these techniques:
class Foo:
import types
def add(self, item, s=Foo.defaultFactory):
if isinstance(s, types.FunctionType): s = s(self)
s.append(item)
def defaultFactory(self):
""" Can be overridden in a subclass, too!"""
return []
It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.
I've always used phpMailer's SMTP feature:
$mail->IsSMTP();
$mail->Host = "localhost";
And if you need debug info:
$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
// 1 = errors and messages
// 2 = messages only
This appears in the context of the Handle-Body-Idiom, also called Pimpl idiom. It allows one to keep the ABI (binary interface) of a library the same, by keeping actual data into another class object, which is merely referenced by a pointer held in an "handle" object, consisting of functions that delegate to that class "Body".
It's also useful to enable constant time and exception safe swap of two objects. For this, merely the pointer pointing to the body object has to be swapped.
use git stash push -m aNameForYourStash
to save it. Then use git stash list
to learn the index of the stash that you want to apply. Then use git stash pop --index 0
to pop the stash and apply it.
note: I'm using git version 2.21.0.windows.1
I faced a problem that I had to use a timer, but I had to display them in 2 component same time, same screen. I created the timerObservable in a service. I subscribed to the timer in both component, and what happened? It won't be synched, cause new subscription always creates its own stream.
What I would like to say, is that if you plan to use one timer at several places, always put .publishReplay(1).refCount()
at the end of the Observer, cause it will publish the same stream out of it every time.
Example:
this.startDateTimer = Observable.combineLatest(this.timer, this.startDate$, (localTimer, startDate) => {
return this.calculateTime(startDate);
}).publishReplay(1).refCount();
Another way to check is to inline the function, so that the condition will be checked on every render (every props and state change)
const isDisabled = () =>
// condition check
This works:
<button
type="button"
disabled={this.isDisabled()}
>
Let Me In
</button>
but this will not work:
<button
type="button"
disabled={this.isDisabled}
>
Let Me In
</button>
Besides what Bert F said, many commands, including log
has the -r
(or --revision
) option. The following are some practical examples using this option to show ranges of revisions:
To list everything in ascending order:
svn log -r 1:HEAD
To list everything in descending order:
svn log -r HEAD:1
To list everything from the thirteenth to the base of the currently checked-out revision in ascending order:
svn log -r 13:BASE
To get everything between the given dates:
svn log -r {2011-02-02}:{2011-02-03}
You can combine all the above expressions with the --limit
option, so that can you have a quite granular control over what is printed. For more info about these -r
expressions refer to svn help log
or the relevant chapter in the book Version Control with Subversion

os.unlink(path, *, dir_fd=None)
or
os.remove(path, *, dir_fd=None)
Both functions are semantically same. This functions removes (deletes) the file path. If path is not a file and it is directory, then exception is raised.
shutil.rmtree(path, ignore_errors=False, onerror=None)
or
os.rmdir(path, *, dir_fd=None)
In order to remove whole directory trees, shutil.rmtree()
can be used. os.rmdir
only works when the directory is empty and exists.
os.removedirs(name)
It remove every empty parent directory with self until parent which has some content
ex. os.removedirs('abc/xyz/pqr') will remove the directories by order 'abc/xyz/pqr', 'abc/xyz' and 'abc' if they are empty.
For more info check official doc: os.unlink
, os.remove
, os.rmdir
, shutil.rmtree
, os.removedirs
A database is the main container, it contains the data and log files, and all the schemas within it. You always back up a database, it is a discrete unit on its own.
Schemas are like folders within a database, and are mainly used to group logical objects together, which leads to ease of setting permissions by schema.
drop schema test1
Msg 3729, Level 16, State 1, Line 1
Cannot drop schema 'test1' because it is being referenced by object 'copyme'.
You cannot drop a schema when it is in use. You have to first remove all objects from the schema.

I suggest you to go to Query Browser and do the following:
Go to schemata and find the table you want to alter.
Right click and select copy create statement.
Open a result tab and paste the create statement their.
Go to the last line of the create statement and look for the Auto_Increment=N, (Where N is a current number for auto_increment field.)
Replace N with 1.
Press ctrl+enter.
Auto_increment should reset to one once you enter new row int the table.
I don't know what will happen if you try to add a row where an auto_increment field value already exist.
There is a great library to make your life easier Dapper.Contrib.Extensions. After including this you can just write:
public int Add(Transaction transaction)
{
using (IDbConnection db = Connection)
{
return (int)db.Insert(transaction);
}
}
I've been using this function for a while. Removes pretty much any messy html you can throw at it and leaves the text intact.

Just use the below formation###
rules_id = ["9","10"]
sql2 = "SELECT * FROM attendance_rules_staff WHERE id in"+str(tuple(rules_id))
note the str(tuple(rules_id))
.
You can try to do my answer,
you wrote this:
<?php
foreach($group_membership as $i => $username) {
$items = array($username);
}
print_r($items);
?>
And in your case I would do this:
<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
$items[] = $username;
} ?>
As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)
<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
$items[] = $username;
}
?>
while
is faster, but the last example is only a result of an observation. :)
Basic approach:
This should add HTML-formatted content and show the newly added row.
var myHtmlContent = "<h3>hello</h3>"
var tableRef = document.getElementById('myTable').getElementsByTagName('tbody')[0];
var newRow = tableRef.insertRow(tableRef.rows.length);
newRow.innerHTML = myHtmlContent;
I assume this is running on a server where the zip application is in the search path. Should be true for all unix-based and I guess most windows-based servers.
exec('zip -r archive.zip "My folder"');
unlink('My\ folder/index.html');
unlink('My\ folder/picture.jpg');
The archive will reside in archive.zip afterwards. Keep in mind that blanks in file or folder names are a common cause of errors and should be avoided where possible.

I had a requirement to filter out the system apps which user do not really use(eg. "com.qualcomm.service", "update services", etc). Ultimately I added another condition to filter down the app list. I just checked whether the app has 'launcher intent'.
So, the resultant code looks like...
PackageManager pm = getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(PackageManager.GET_GIDS);
for (ApplicationInfo app : apps) {
if(pm.getLaunchIntentForPackage(app.packageName) != null) {
// apps with launcher intent
if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
// updated system apps
} else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
// system apps
} else {
// user installed apps
}
appsList.add(app);
}
}
If you are using Linux, these settings are available using /usr/bin/jcontrol
(or your path setting to get the current Java tools). You can also edit the files in ~/.java/deployment/deployment.properties
to set "deployment.security.level=MEDIUM".
Surprisingly, this information is not readily available from the Oracle web site. I miss java.sun.com...
Another approach that is especially useful if you want to store data coming from an external API or a DB would be this:
Create a class that represent your data model
export class Data{
private id:number;
private text: string;
constructor(id,text) {
this.id = id;
this.text = text;
}
In your component class you create an empty array of type Data
and populate this array whenever you get a response from API or whatever data source you are using
export class AppComponent {
private search_key: string;
private dataList: Data[] = [];
getWikiData() {
this.httpService.getDataFromAPI()
.subscribe(data => {
this.parseData(data);
});
}
parseData(jsonData: string) {
//considering you get your data in json arrays
for (let i = 0; i < jsonData[1].length; i++) {
const data = new WikiData(jsonData[1][i], jsonData[2][i]);
this.wikiData.push(data);
}
}
}
Just convert the text explicitly to string using str()
. Worked for me.
vector.clear()
should work for you. In case you want to shrink the capacity of the vector
along with clear then
std::vector<T>(v).swap(v);
You must understand , threads scheduling is controlled by thread scheduler.So, you cannot guarantee the order of execution of threads under normal circumstances.
However, you can use join()
to wait for a thread to complete its work.
For example, in your case
ob1.t.join();
This statement will not return until thread t
has finished running.
Try this,
class Demo {
Thread t = new Thread(
new Runnable() {
public void run () {
//do something
}
}
);
Thread t1 = new Thread(
new Runnable() {
public void run () {
//do something
}
}
);
t.start(); // Line 15
t.join(); // Line 16
t1.start();
}
In the above example, your main thread is executing. When it encounters line 15, thread t is available at thread scheduler. As soon as main thread comes to line 16, it will wait for thread t
to finish.
NOTE that t.join
did not do anything to thread t
or to thread t1
. It only affected the thread that called it (i.e., the main()
thread).
Edited:
t.join();
needs to be inside the try
block because it throws
the InterruptedException
exception, otherwise you will get an error at compile time. So, it should be:
try{
t.join();
}catch(InterruptedException e){
// ...
}
An XPath solution is to use:
string-length((//div[@class='contest'])[$k])
where $k should be substituted by a number.
This evaluates to the string length of the $k-th (in document order) div
in the XML document that has a class
attribute with value 'contest'.
I know this is an old post but try using an extension method:
public static IEnumerable<DateTime> Range(this DateTime startDate, DateTime endDate)
{
return Enumerable.Range(0, (endDate - startDate).Days + 1).Select(d => startDate.AddDays(d));
}
and use it like this
var dates = new DateTime(2000, 1, 1).Range(new DateTime(2000, 1, 31));
Feel free to choose your own dates, you don't have to restrict yourself to January 2000.
checked :
public Constructor(Class<E> c, int length) {
elements = (E[]) Array.newInstance(c, length);
}
or unchecked :
public Constructor(int s) {
elements = new Object[s];
}
Generator Function, Generator Object, Generator:
A Generator function is just like a regular function in Python but it contains one or more yield
statements. Generator functions is a great tool to create Iterator objects as easy as possible. The Iterator object returend by generator function is also called Generator object or Generator.
In this example I have created a Generator function which returns a Generator object <generator object fib at 0x01342480>
. Just like other iterators, Generator objects can be used in a for
loop or with the built-in function next()
which returns the next value from generator.
def fib(max):
a, b = 0, 1
for i in range(max):
yield a
a, b = b, a + b
print(fib(10)) #<generator object fib at 0x01342480>
for i in fib(10):
print(i) # 0 1 1 2 3 5 8 13 21 34
print(next(myfib)) #0
print(next(myfib)) #1
print(next(myfib)) #1
print(next(myfib)) #2
So a generator function is the easiest way to create an Iterator object.
Iterator:
Every generator object is an iterator but not vice versa. A custom iterator object can be created if its class implements __iter__
and __next__
method (also called iterator protocol).
However, it is much easier to use generators function to create iterators because they simplify their creation, but a custom Iterator gives you more freedom and you can also implement other methods according to your requirements as shown in the below example.
class Fib:
def __init__(self,max):
self.current=0
self.next=1
self.max=max
self.count=0
def __iter__(self):
return self
def __next__(self):
if self.count>self.max:
raise StopIteration
else:
self.current,self.next=self.next,(self.current+self.next)
self.count+=1
return self.next-self.current
def __str__(self):
return "Generator object"
itobj=Fib(4)
print(itobj) #Generator object
for i in Fib(4):
print(i) #0 1 1 2
print(next(itobj)) #0
print(next(itobj)) #1
print(next(itobj)) #1
Use the WScript.Shell instead, because it has a waitOnReturn
option:
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "C:\folder\runbat.bat", windowStyle, waitOnReturn
(Idea copied from Wait for Shell to finish, then format cells - synchronously execute a command)
You need a parameterless constructor to be able to create an instance of your class. Your current constructor requires two input string parameters.
Normally C++ implies having such a constructor (=default parameterless constructor) if there is no other constructor declared. By declaring your first constructor with two parameters you overwrite this default behaviour and now you have to declare this constructor explicitly.
Here is the working code:
#include <iostream>
#include <string> // <-- you need this if you want to use string type
using namespace std;
class name {
public:
string first;
string last;
name(string a, string b){
first = a;
last = b;
}
name () // <-- this is your explicit parameterless constructor
{}
};
int main (int argc, const char * argv[])
{
const int howManyNames = 3;
name someName[howManyNames];
return 0;
}
(BTW, you need to include to make the code compilable.)
An alternative way is to initialize your instances explicitly on declaration
name someName[howManyNames] = { {"Ivan", "The Terrible"}, {"Catherine", "The Great"} };
The metaclass-based answers still work in Python 3, but instead of the __metaclass__
attribute, one has to use the metaclass
parameter, as in:
class ExampleTestCase(TestCase,metaclass=DocTestMeta):
pass
Lots of unnecessary flooring in other answers. If the string is in milliseconds, convert to h:m:s as follows:
function msToTime(s) {
var ms = s % 1000;
s = (s - ms) / 1000;
var secs = s % 60;
s = (s - secs) / 60;
var mins = s % 60;
var hrs = (s - mins) / 60;
return hrs + ':' + mins + ':' + secs + '.' + ms;
}
If you want it formatted as hh:mm:ss.sss then use:
function msToTime(s) {_x000D_
_x000D_
// Pad to 2 or 3 digits, default is 2_x000D_
function pad(n, z) {_x000D_
z = z || 2;_x000D_
return ('00' + n).slice(-z);_x000D_
}_x000D_
_x000D_
var ms = s % 1000;_x000D_
s = (s - ms) / 1000;_x000D_
var secs = s % 60;_x000D_
s = (s - secs) / 60;_x000D_
var mins = s % 60;_x000D_
var hrs = (s - mins) / 60;_x000D_
_x000D_
return pad(hrs) + ':' + pad(mins) + ':' + pad(secs) + '.' + pad(ms, 3);_x000D_
}_x000D_
_x000D_
console.log(msToTime(55018))
_x000D_
Using some recently added language features, the pad function can be more concise:
function msToTime(s) {_x000D_
// Pad to 2 or 3 digits, default is 2_x000D_
var pad = (n, z = 2) => ('00' + n).slice(-z);_x000D_
return pad(s/3.6e6|0) + ':' + pad((s%3.6e6)/6e4 | 0) + ':' + pad((s%6e4)/1000|0) + '.' + pad(s%1000, 3);_x000D_
}_x000D_
_x000D_
// Current hh:mm:ss.sss UTC_x000D_
console.log(msToTime(new Date() % 8.64e7))
_x000D_
For me, line numbers wouldn't appear in the editor until I added the option under both the "all languages" pane, and the language I was working under (C# etc)... screen capture showing editor options
Replacing forward(/) slash with backward(\) slash will do the job. The folder separator in Windows is \ not /
I was also facing the same issue as you did. Here is what I did to solve:
METHOD 1
This is what I tried, and I did not need to logout from any sessions from TFS or VS Account.
METHOD 2
This is also easy method.
Hope this helps.
Not the right function name I think
$(document).ready(function() {
$('.datepicker').datetimepicker({
format: 'dd/mm/yyyy'
});
});
Here's the implementation in JOSM:
/**
* Returns the Java version as an int value.
* @return the Java version as an int value (8, 9, etc.)
* @since 12130
*/
public static int getJavaVersion() {
String version = System.getProperty("java.version");
if (version.startsWith("1.")) {
version = version.substring(2);
}
// Allow these formats:
// 1.8.0_72-ea
// 9-ea
// 9
// 9.0.1
int dotPos = version.indexOf('.');
int dashPos = version.indexOf('-');
return Integer.parseInt(version.substring(0,
dotPos > -1 ? dotPos : dashPos > -1 ? dashPos : 1));
}

Many people advise using col-
and col-offset-
classes, but it doesn't work right for me, it centers the form only for a certain screen size, but if you change it, the markup slides out.
I found two ways to align form:
Use a custom CSS:
<div class=".center">
<form>
</form>
</div>
.center {
margin: 0 auto;
width: 100%;
}
form {
margin: 0 auto;
width: 500px; /*find your value*/
text-align: center;
}
OR just copy a CSS class "justify-content-center" from bootstrap 4, it's very short:
.justify-content-center {
-ms-flex-pack: center !important;
justify-content: center !important;
}
And then use it:
<div class="container">
<div class="row">
<div class="form-inline justify-content-center">
</div>
</div>
</div>
Here is the Android version based on @Yodacheese's C# answer using Google Maps api:

}
double x = 0;
double y = 0;
double z = 0;
for(LatLng geoCoordinate : geoCoordinates)
{
double latitude = geoCoordinate.latitude * Math.PI / 180;
double longitude = geoCoordinate.longitude * Math.PI / 180;
x += Math.cos(latitude) * Math.cos(longitude);
y += Math.cos(latitude) * Math.sin(longitude);
z += Math.sin(latitude);
}
int total = geoCoordinates.size();
x = x / total;
y = y / total;
z = z / total;
double centralLongitude = Math.atan2(y, x);
double centralSquareRoot = Math.sqrt(x * x + y * y);
double centralLatitude = Math.atan2(z, centralSquareRoot);
return new LatLng(centralLatitude * 180 / Math.PI, centralLongitude * 180 / Math.PI);
}
in app build.gradle add:

Okay, I'll bite. You want something like this: If you declare a "property" like this:
Update: I'm now pretty sure that Fredrik Mörk answered your question and gave a solution. I'm not really happy with the idea, but it seems to answer exactly what I understood from your question.
public class PropertyFoo {
public MyProp<String> Name;
}
this ends up as
public class PropertyFoo {
public string Name {
get { /* do predefined stuff here */ }
set { /*other predefined stuff here */ }
}
}
No. Not possible and not a property, really. Look for template/snippet support in your IDE.
On Django 1.2, {{ form.data.field }} and {{ form.field.data }} are all OK, but not {{ form.field.value }}.
As others said, {{ form.field.value }} is Django 1.3+ only, but there's no specification in https://docs.djangoproject.com/en/1.3/topics/forms/. It can be found in https://docs.djangoproject.com/en/1.4/topics/forms/.
i found this way useful also.

Short answer: No, only the path and protocol field can be specified.
Longer answer:
There is no method in the JavaScript WebSockets API for specifying additional headers for the client/browser to send. The HTTP path ("GET /xyz") and protocol header ("Sec-WebSocket-Protocol") can be specified in the WebSocket constructor.
The Sec-WebSocket-Protocol header (which is sometimes extended to be used in websocket specific authentication) is generated from the optional second argument to the WebSocket constructor:
var ws = new WebSocket("ws://example.com/path", "protocol");
var ws = new WebSocket("ws://example.com/path", ["protocol1", "protocol2"]);
The above results in the following headers:
Sec-WebSocket-Protocol: protocol
and
Sec-WebSocket-Protocol: protocol1, protocol2
A common pattern for achieving WebSocket authentication/authorization is to implement a ticketing system where the page hosting the WebSocket client requests a ticket from the server and then passes this ticket during WebSocket connection setup either in the URL/query string, in the protocol field, or required as the first message after the connection is established. The server then only allows the connection to continue if the ticket is valid (exists, has not been already used, client IP encoded in ticket matches, timestamp in ticket is recent, etc). Here is a summary of WebSocket security information: https://devcenter.heroku.com/articles/websocket-security
Basic authentication was formerly an option but this has been deprecated and modern browsers don't send the header even if it is specified.
Basic Auth Info (Deprecated - No longer functional):
NOTE: the following information is no longer accurate in any modern browsers.
The Authorization header is generated from the username and password (or just username) field of the WebSocket URI:
var ws = new WebSocket("ws://username:[email protected]")
The above results in the following header with the string "username:password" base64 encoded:
Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
I have tested basic auth in Chrome 55 and Firefox 50 and verified that the basic auth info is indeed negotiated with the server (this may not work in Safari).
Thanks to Dmitry Frank's for the basic auth answer
Something like this should work:
<%=Html.TextBox("test", new { style="width:50px" })%>
Or better:
<%=Html.TextBox("test")%>
<style type="text/css">
input[type="text"] { width:50px; }
</style>
I know this is a little late, however for anyone interested, I've created a custom component that is basically a toggle image button, the drawable can have states as well as the background
You can pass this
when you call the function
<button onclick="doSomething('param',this)" id="id_button">action</button>
<script>
function doSomething(param,me){
var source = me
console.log(source);
}
</script>
Use
rm -rf *
Update: The .
stands for current directory, but we cannot use this. The command seems to have explicit checks for .
and ..
. Use the wildcard globbing instead. But this can be risky.
A safer version IMO is to use:
rm -ri *
(this prompts you for confirmation before deleting every file/directory.)
I faced the same problem while installing Eclipse for c/c++ applications .I downloaded Mingw GCC ,put its bin folder in your path ,used it in toolchains while making new C++ project in Eclipse and build which solved my problem. Referred to this video
Comprehension could be also convenient in this case:
# from a list
keys = ["k1", "k2"]
d = {k:None for k in keys}
# or from another dict
d1 = {"k1" : 1, "k2" : 2}
d2 = {k:None for k in d1.keys()}
d2
# {'k1': None, 'k2': None}
I solved the same error, by adding "zizaco/entrust": "*"
instead of the "zizaco/entrust": "~1.2"
.
I think I got what I was looking for..
data.train <- read.table("Assign2.WineComplete.csv",sep=",",header=T)
fit <- rpart(quality ~ ., method="class",data=data.train)
plot(fit)
text(fit, use.n=TRUE)
summary(fit)
Yes, it's possible. In python, Comprehension can be used in List, Set, Dictionary, etc. You can write it this way
mydict = {k:v for (k,v) in blah}
Another detailed example of Dictionary Comprehension with the Conditional Statement and Loop:
parents = [father, mother]
parents = {parent:1 - P["mutation"] if parent in two_genes else 0.5 if parent in one_gene else P["mutation"] for parent in parents}
Here's a query to update a table based on a comparison of another table. If record is not found in tableB, it will update the "active" value to "n". If it's found, will set the value to NULL
UPDATE tableA
LEFT JOIN tableB ON tableA.id = tableB.id
SET active = IF(tableB.id IS NULL, 'n', NULL)";
Hope this helps someone else.
Use this line of code in your css
border: 1px solid #000 !important;
or if you want border only in left and right side of container then use:
border-right: 1px solid #000 !important;
border-left: 1px solid #000 !important;
Simply use the on click event for tab shown.
$(document).on('shown.bs.tab', 'a[href="#tab"]', function (){
});
Well, my case when you don't want to care about files list. Just show them all.
When you already ran git add
with your files list:
$ git diff --cached $(git diff --cached --name-only)
In more recent versions of git
, you can use --staged
also, which is a synonym of --cached
.
The same can be used for haven't added files but without --cached
option.
$ git diff $(git diff --name-only)
Git command alias for "cached" option:
$ git config --global alias.diff-cached '!git diff --cached $(git diff --cached --name-only)'
The CSS below stops users from being able to select text.
-webkit-user-select: none; /* Safari */
-moz-user-select: none; /* Firefox */
-ms-user-select: none; /* IE10+/Edge */
user-select: none; /* Standard */
To target IE9 downwards the html attribute unselectable
must be used instead:
<p unselectable="on">Test Text</p>
If you want to swap string. it's already the efficient way to do that.
However, if you want to swap integer, you can use XOR to swap two integers more efficiently like this:
int a = 1; int b = 2; a ^= b; b ^= a; a ^= b;
In Python 3.6+ you could use Variable Annotations for this:
https://www.python.org/dev/peps/pep-0526/#abstract
PEP 484 introduced type hints, a.k.a. type annotations. While its main focus was function annotations, it also introduced the notion of type comments to annotate variables:
# 'captain' is a string (Note: initial value is a problem)
captain = ... # type: str
PEP 526 aims at adding syntax to Python for annotating the types of variables (including class variables and instance variables), instead of expressing them through comments:
captain: str # Note: no initial value!
It seems to be more directly in line with what you were asking "Is it possible only to declare a variable without assigning any value in Python?"
The error comes when you try to call sum(x)
and x
is a factor.
What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)
simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:
family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))
For a detailed explanation of why the intermediate as.character
step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?
Instant
corresponds to time on the prime meridian (Greenwich).
Whereas LocalDateTime
relative to OS time zone settings, and
cannot represent an instant without additional information such as an offset or time-zone.
unset($a->new_property);
This works for array elements, variables, and object attributes.
Example:
$a = new stdClass();
$a->new_property = 'foo';
var_export($a); // -> stdClass::__set_state(array('new_property' => 'foo'))
unset($a->new_property);
var_export($a); // -> stdClass::__set_state(array())
Here's what worked for me:
select visits, activations, simulations, simulations/activations
as sims_per_visit, activations/visits*100
as adoption_rate, simulations/activations*100
as completion_rate, duration/60
as minutes, m1 as month, Wk1 as week, Yr1 as year
from
(
(select count(*) as visits, year(stamp) as Yr1, week(stamp) as Wk1, month(stamp)
as m1 from sessions group by week(stamp), year(stamp)) as t3
join
(select count(*) as activations, year(stamp) as Yr2, week(stamp) as Wk2,
month(stamp) as m2 from sessions where activated='1' group by week(stamp),
year(stamp)) as t4
join
(select count(*) as simulations, year(stamp) as Yr3 , week(stamp) as Wk3,
month(stamp) as m3 from sessions where simulations>'0' group by week(stamp),
year(stamp)) as t5
join
(select avg(duration) as duration, year(stamp) as Yr4 , week(stamp) as Wk4,
month(stamp) as m4 from sessions where activated='1' group by week(stamp),
year(stamp)) as t6
)
where Yr1=Yr2 and Wk1=Wk2 and Wk1=Wk3 and Yr1=Yr3 and Yr1=Yr4 and Wk1=Wk4
I used joins, not unions (I needed different columns for each query, a join puts it all in the same column) and I dropped the quotation marks (compared to what Liam was doing) because they were giving me errors.
Thanks! I couldn't have pulled that off without this page! PS: Sorry I don't know how you're getting your statements formatted with colors. etc.
Interesting to note, all sources emphasize that @Column(nullable=false) is used only for DDL generation.
However, even if there is no @NotNull annotation, and hibernate.check_nullability option is set to true, Hibernate will perform validation of entities to be persisted.
It will throw PropertyValueException saying that "not-null property references a null or transient value", if nullable=false attributes do not have values, even if such restrictions are not implemented in the database layer.
More information about hibernate.check_nullability option is available here: http://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#configurations-mapping.
The SET
command is TSQL specific - here's the PLSQL equivalent to what you posted:
v_date1 DATE := TO_DATE('03-AUG-2010', 'DD-MON-YYYY');
SELECT u.visualid
FROM USAGE u
WHERE u.usetime > v_date1;
There's also no need for prefixing variables with "@"; I tend to prefix variables with "v_" to distinguish between variables & columns/etc.
In my opinion, interface has a broader meaning than the one commonly associated with it in Java. I would define "interface" as a set of available operations with some common functionality, that allow controlling/monitoring a module.
In this definition I try to cover both programatic interfaces, where the client is some module, and human interfaces (GUI for example).
As others already said, an interface always has some contract behind it, in terms of inputs and outputs. The interface does not promise anything about the "how" of the operations; it only guarantees some properties of the outcome, given the current state, the selected operation and its parameters.
Look for them under COM when trying to add the references. You should find the reference below, and possibly Microsoft Outlook 15.0 Object Library, if you need that. There are similar libraries for Word, Excel, etc.:
Update: The Object Library should contain the Interop stuff. Try to add this to a source file, and see if it does not find what you need:
using Microsoft.Office.Interop.Outlook;
You need to do two additional things after following the link that you have mentioned in your post:
One have to map the changed login cridentials in phpmyadmin's config.inc.php
and second, you need to restart your web and mysql servers..
php version is not the issue here..you need to go to phpmyadmin installation directory and find file config.inc.php
and in that file put your current mysql password at line
$cfg['Servers'][$i]['user'] = 'root'; //mysql username here
$cfg['Servers'][$i]['password'] = 'password'; //mysql password here
If you want to upload a folder or a file to Github
1- Create a repository on the Github
2- make: git remote add origin "Your Link" as it is described on the Github
3- Then use git push -u origin master.
4- You have to enter your username and Password.
5- After the authentication, the transfer will start
Instead of
CGContextDrawImage(context, CGRectMake(0, 0, 145, 15), image.CGImage);
Use
[image drawInRect:CGRectMake(0, 0, 145, 15)];
In the middle of your begin/end CGcontext
methods.
This will draw the image with the correct orientation into your current image context - I'm pretty sure this has something to do with the UIImage
holding onto knowledge of the orientation while the CGContextDrawImage
method gets the underlying raw image data with no understanding of orientation.

You are not comparing dates. You are comparing strings. In the world of string comparisons, 09/17/2015
> 01/02/2016
because 09
> 01
. You need to either put your date in a comparable string format or compare DateTime
objects which are comparable.
<?php
$date_now = date("Y-m-d"); // this format is string comparable
if ($date_now > '2016-01-02') {
echo 'greater than';
}else{
echo 'Less than';
}
Or
<?php
$date_now = new DateTime();
$date2 = new DateTime("01/02/2016");
if ($date_now > $date2) {
echo 'greater than';
}else{
echo 'Less than';
}
i experienced a similar issue. Bitdefender automatically quarantined each exe-file i created by MinGW g++. Instead of the full exe-file i found a file with a weird extension 'qzquar' testAutoPtr1.exe.48352.gzquar
When i opened quarantined items in Bitdefender i found my exe-file quarantined there.
My usecase was replacing None
with some default value.
I've timed approaches to this problem that were presented here, including the one by @kxr - using str.count
.
Test code in ipython with Python 3.8.1:
def rep1(lst, replacer = 0):
''' List comprehension, new list '''
return [item if item is not None else replacer for item in lst]
def rep2(lst, replacer = 0):
''' List comprehension, in-place '''
lst[:] = [item if item is not None else replacer for item in lst]
return lst
def rep3(lst, replacer = 0):
''' enumerate() with comparison - in-place '''
for idx, item in enumerate(lst):
if item is None:
lst[idx] = replacer
return lst
def rep4(lst, replacer = 0):
''' Using str.index + Exception, in-place '''
idx = -1
# none_amount = lst.count(None)
while True:
try:
idx = lst.index(None, idx+1)
except ValueError:
break
else:
lst[idx] = replacer
return lst
def rep5(lst, replacer = 0):
''' Using str.index + str.count, in-place '''
idx = -1
for _ in range(lst.count(None)):
idx = lst.index(None, idx+1)
lst[idx] = replacer
return lst
def rep6(lst, replacer = 0):
''' Using map, return map iterator '''
return map(lambda item: item if item is not None else replacer, lst)
def rep7(lst, replacer = 0):
''' Using map, return new list '''
return list(map(lambda item: item if item is not None else replacer, lst))
lst = [5]*10**6
# lst = [None]*10**6
%timeit rep1(lst)

I get:
26.3 ms ± 163 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
29.3 ms ± 206 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
33.8 ms ± 191 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
11.9 ms ± 37.8 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

56.5 ms ± 204 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)
Using the internal str.index
is in fact faster than any manual comparison.
I didn't know if the exception in test 4 would be more laborious than using str.count
, the difference seems negligible.
Note that map()
(test 6) returns an iterator and not an actual list, thus test 7.

const obj = {one:1, two:2, three:3};
let arr = [];
for(let p in obj)
arr.push(obj[p]);

As integers are comparable we can use the following one liner in:
List<Integer> ints = Stream.of(22,44,11,66,33,55).collect(Collectors.toList());
Integer max = ints.stream().mapToInt(i->i).max().orElseThrow(NoSuchElementException::new); //66
Integer min = ints.stream().mapToInt(i->i).min().orElseThrow(NoSuchElementException::new); //11
Another point to note is we cannot use Funtion.identity()
in place of i->i
as mapToInt
expects ToIntFunction
which is a completely different interface and is not related to Function
. Moreover this interface has only one method applyAsInt
and no identity()
method.

onActivityCreated()
is now deprecated as Fragments Version 1.3.0-alpha02
The onActivityCreated() method is now deprecated. Code touching the fragment's view should be done in onViewCreated() (which is called immediately before onActivityCreated()) and other initialization code should be in onCreate(). To receive a callback specifically when the activity's onCreate() is complete, a LifeCycleObserver should be registered on the activity's Lifecycle in onAttach(), and removed once the onCreate() callback is received.

Use the Path
class from System.IO
. It contains useful calls for manipulating file paths, including GetDirectoryName
which does what you want, returning the directory portion of the file path.
Usage is simple.
string directoryPath = System.IO.Path.GetDirectoryName(choofdlog.FileName);
Also you can use 'ODBC' + 'SQL Server Import and Export Wizard'. Below link describes it: https://www.mssqltips.com/sqlservertutorial/2205/mysql-to-sql-server-data-migration/
You can use Named Sections.
_Layout.cshtml

@RenderSection("JavaScript", required: false)
</head>

I came up with some kind of solution to the problem. It involves jquery and css. This works like toggle but instead of toggling the display of elements it just changes its properties upon alternate clicks. Upon clicking the div it rotates the element with tag 180 degrees and when you click it again the element with tag returns to its original position. If you want to change the animation duration just change transition-duration property.
CSS
#example1{
transition-duration:1s;
}
jQuery
$(document).ready( function () { var toggle = 1;
$('div').click( function () {
toggle++;
if ( (toggle%2)==0){
$('#example1').css( {'transform': 'rotate(180deg)'});
}
else{
$('#example1').css({'transform': 'rotate(0deg)'});
}
});
});

Take out the method name from in your import statement. e.g.
import Dan.Vik.disp;
becomes:
import Dan.Vik;
describe('testing a method() on a service', function () {
var mock, service
function init(){
return angular.mock.inject(function ($injector,, _serviceUnderTest_) {
mock = $injector.get('service_that_is_being_mocked');;
service = __serviceUnderTest_;
});
}
beforeEach(module('yourApp'));
beforeEach(init());
it('that has a then', function () {
//arrange
var spy= spyOn(mock, 'actionBeingCalled').and.callFake(function () {
return {
then: function (callback) {
return callback({'foo' : "bar"});
}
};
});
//act
var result = service.actionUnderTest(); // does cleverness
//assert
expect(spy).toHaveBeenCalled();
});
});
Below is one of the way by which you can achieve that, may not be an ideal way to do.
Have one method accepting both types of request, then check what type of request you received, is it of type "GET" or "POST", once you come to know that, do respective actions and the call one method which does common task for both request Methods ie GET and POST.
@RequestMapping(value = "/books")
public ModelAndView listBooks(HttpServletRequest request){
//handle both get and post request here
// first check request type and do respective actions needed for get and post.
if(GET REQUEST){
//WORK RELATED TO GET
}else if(POST REQUEST){
//WORK RELATED TO POST
}
commonMethod(param1, param2....);
}
Try using the type

}
Postgres hasn't implemented an equivalent to INSERT OR REPLACE
. From the ON CONFLICT
docs (emphasis mine):
It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.
Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE
applies more generally, since it lets you set new values based on preexisting data. For example:
INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.
Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.
Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.
In VirtualBox screen, go to Devices>USB devices. Select your dongle.
Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.
Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.
Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .
For those folks who are using WebDriverJS Keys.RETURN
would be referenced as
webdriver.Key.RETURN
A more complete example as a reference might be helpful too:
var pressEnterToSend = function () {
var deferred = webdriver.promise.defer();
webdriver.findElement(webdriver.By.id('id-of-input-element')).then(function (element) {
element.sendKeys(webdriver.Key.RETURN);
deferred.resolve();
});
return deferred.promise;
};
you are describing a Problem, which I would try to solve with the VLOOKUP function rather than using VBA.
You should always consider a non-vba solution first.
Here are some application examples of VLOOKUP (or SVERWEIS in German, as i know it):
http://www.youtube.com/watch?v=RCLUM0UMLXo
http://office.microsoft.com/en-us/excel-help/vlookup-HP005209335.aspx
If you have to make it as a macro, you could use VLOOKUP as an application function - a quick solution with slow performance - or you will have to make a simillar function yourself.
If it has to be the latter, then there is need for more details on your specification, regarding performance questions.
You could copy any range to an array, loop through this array and check for your value, then copy this value to any other range. This is how i would solve this as a vba-function.
This would look something like that:
Public Sub CopyFilter()
Dim wks As Worksheet
Dim avarTemp() As Variant
'go through each worksheet
For Each wks In ThisWorkbook.Worksheets
avarTemp = wks.UsedRange
For i = LBound(avarTemp, 1) To UBound(avarTemp, 1)
'check in the first column in each row
If avarTemp(i, LBound(avarTemp, 2)) = "XYZ" Then
'copy cell
targetWks.Cells(1, 1) = avarTemp(i, LBound(avarTemp, 2))
End If
Next i
Next wks
End Sub
Ok, now i have something nice which could come in handy for myself:
Public Function FILTER(ByRef rng As Range, ByRef lngIndex As Long) As Variant
Dim avarTemp() As Variant
Dim avarResult() As Variant
Dim i As Long
avarTemp = rng
ReDim avarResult(0)
For i = LBound(avarTemp, 1) To UBound(avarTemp, 1)
If avarTemp(i, 1) = "active" Then
avarResult(UBound(avarResult)) = avarTemp(i, lngIndex)
'expand our result array
ReDim Preserve avarResult(UBound(avarResult) + 1)
End If
Next i
FILTER = avarResult
End Function
You can use it in your Worksheet like this =FILTER(Tabelle1!A:C;2) or with =INDEX(FILTER(Tabelle1!A:C;2);3) to specify the result row. I am sure someone could extend this to include the index functionality into FILTER or knows how to return a range like object - maybe I could too, but not today ;)
What if your lists contain duplicates like this:
v1 = ['s', 'h', 'e', 'e', 'p']
v2 = ['s', 's', 'h']
Sets do not contain duplicates. So, the following line returns True.
set(v2).issubset(v1)
To count for duplicates, you can use the code:
v1 = sorted(v1)
v2 = sorted(v2)
def is_subseq(v2, v1):
"""Check whether v2 is a subsequence of v1."""
it = iter(v1)
return all(c in it for c in v2)
So, the following line returns False.
is_subseq(v2, v1)
The "in" in Linq-To-Sql uses a reverse logic compared to a SQL query.
Let's say you have a list of integers, and want to find the items that match those integers.
int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
var items = from p in context.Items
where numbers.Contains(p.ItemId)
select p;
Anyway, the above works fine in linq-to-sql but not in EF 1.0. Haven't tried it in EF 4.0
A simpler approach would be:
Hope this helps!
Well, you could use nohup to run whatever you are running on 'non-blocking mode'. So you can just keep checking if whatever it was supposed to run, ran, otherwise exit.
nohup ./my-script-that-may-take-long-to-finish.sh & ./check-if-previous-script-ran-or-exit.sh
echo "Script ended on Feb 15, 2011, 9:20AM" > /tmp/done.txt
So in the second one you just check if the file exists.
You could use the object data type:
>>> import numpy
>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)
All numbers in Lua are floats (edit: Lua 5.2 or less). If you truly want to convert to an "int" (or at least replicate this behavior), you can do this:
local function ToInteger(number)
return math.floor(tonumber(number) or error("Could not cast '" .. tostring(number) .. "' to number.'"))
end
In which case you explicitly convert the string (or really, whatever it is) into a number, and then truncate the number like an (int) cast would do in Java.
Edit: This still works in Lua 5.3, even thought Lua 5.3 has real integers, as math.floor()
returns an integer, whereas an operator such as number // 1
will still return a float if number
is a float.

I have solved this issue by storing images on internal storage and then using .setImageURI() rather than .setBitmap().
The procedures outlined here do not work for Android 7 (Nougat) [and possibly Android 6, but I'm unable to verify]. You can't pull the .apk files directly under Nougat (unless in root mode, but that requires a rooted phone). But, you can copy the .apk to an alternate path (say /sdcard/Download) on the phone using adb shell, then you can do an adb pull from the alternate path.
Months after this question, I've levelup my Docker skills. I should use Docker container name instead.
That use dokerized-nginx as bridge to expose ip+port of the container.
Within WEB configuration, I now use mysql://USERNAME:PASSWORD@docker_container_name/DB_NAME
to access to Mysql socket through docker (also works with docker-compose, use compose-name instead of container one)
Try removing the .
before the .bmp
(it isn't matching BMP
as expected). As you can see from the error, the save_handler
is upper-casing the format
you provided and then looking for a match in SAVE
. However the corresponding key in that object is BMP
(instead of .BMP
).
I don't know a great deal about PIL
, but from some quick searching around it seems that it is a problem with the mode
of the image. Changing the definition of j
to:
j = Image.fromarray(b, mode='RGB')
Seemed to work for me (however note that I have very little knowledge of PIL
, so I would suggest using @mmgp's solution as s/he clearly knows what they are doing :) ). For the types of mode
, I used this page - hopefully one of the choices there will work for you.
