What about
DT <- data.table(test)
setkey(DT, id)
DT[J(unique(id)), mult = "first"]
There is also a unique method for data.tables
which will return the the first row by key
jdtu <- function() unique(DT)
I think, if you are ordering test
outside the benchmark, then you can removing the setkey
and data.table
conversion from the benchmark as well (as the setkey basically sorts by id, the same as order
).
set.seed(21)
test <- data.frame(id=sample(1e3, 1e5, TRUE), string=sample(LETTERS, 1e5, TRUE))
test <- test[order(test$id), ]
DT <- data.table(DT, key = 'id')
ju <- function() test[!duplicated(test$id),]
jdt <- function() DT[J(unique(id)),mult = 'first']
library(rbenchmark)
benchmark(ju(), jdt(), replications = 5)
## test replications elapsed relative user.self sys.self
## 2 jdt() 5 0.01 1 0.02 0
## 1 ju() 5 0.05 5 0.05 0
and with more data
** Edit with unique method**
set.seed(21)
test <- data.frame(id=sample(1e4, 1e6, TRUE), string=sample(LETTERS, 1e6, TRUE))
test <- test[order(test$id), ]
DT <- data.table(test, key = 'id')
test replications elapsed relative user.self sys.self
2 jdt() 5 0.09 2.25 0.09 0.00
3 jdtu() 5 0.04 1.00 0.05 0.00
1 ju() 5 0.22 5.50 0.19 0.03
The unique method is fastest here.
1.Create a Firebase project in the Firebase console, if you don't already have one. If you already have an existing Google project associated with your app, click Import Google Project. Otherwise, click Create New Project.
2.Click settings and select Permissions.
3.Select Service accounts from the menu on the left.
4.Click Create service account.

The only way I've found to work with files on SharePoint while having to server rights is to map the WebDAV folder to a drive letter. Here's an example for the implementation.
Add references to the following ActiveX libraries in VBA:
wshom.ocx
) - for WshNetworkscrrun.dll
) - for FileSystemObjectCreate a new class module, call it DriveMapper
and add the following code:
Option Explicit
Private oMappedDrive As Scripting.Drive
Private oFSO As New Scripting.FileSystemObject
Private oNetwork As New WshNetwork
Private Sub Class_Terminate()
UnmapDrive
End Sub
Public Function MapDrive(NetworkPath As String) As Scripting.Folder
Dim DriveLetter As String, i As Integer
UnmapDrive
For i = Asc("Z") To Asc("A") Step -1
DriveLetter = Chr(i)
If Not oFSO.DriveExists(DriveLetter) Then
oNetwork.MapNetworkDrive DriveLetter & ":", NetworkPath
Set oMappedDrive = oFSO.GetDrive(DriveLetter)
Set MapDrive = oMappedDrive.RootFolder
Exit For
End If
Next i
End Function
Private Sub UnmapDrive()
If Not oMappedDrive Is Nothing Then
If oMappedDrive.IsReady Then
oNetwork.RemoveNetworkDrive oMappedDrive.DriveLetter & ":"
End If
Set oMappedDrive = Nothing
End If
End Sub
Then you can implement it in your code:
Sub test()
Dim dm As New DriveMapper
Dim sharepointFolder As Scripting.Folder
Set sharepointFolder = dm.MapDrive("http://your/sharepoint/path")
Debug.Print sharepointFolder.Path
End Sub
I don't know if the ChangeDetectorRef
was required when the question was created, but now this is enough:
import { MatTableDataSource } from '@angular/material/table';
// ...
dataSource = new MatTableDataSource<MyDataType>();
refresh() {
this.myService.doSomething().subscribe((data: MyDataType[]) => {
this.dataSource.data = data;
}
}

Cities of the world database donated by MaxMind.com
The company MaxMind.com1 has agreed to release their cities of the world database under the GPL. The database contains locations by country, city, latitude and longitude. There are over 3,047,000 records in the database. For those of you who have tried the location.module with the zipcodes database from CivicSpace, you will recognize how cool it is and how well this fits with that project and therefore Drupal.
Here's another free one that might help you get started.
Creating and maintaining such a database is quite a bit of work - so anyone who's done it is likely keeping it to themselves, or offering it for a fee.

John Montgomery's, answer is great, but at least on Windows, it is missing the line
vc.release()
before
cv2.destroyWindow("preview")
Without it, the camera resource is locked, and can not be captured again before the python console is killed.
Following the greenhoorn's answer, you can use "Extensions" like this:
public static class HttpClientExtensions
{
public static HttpClient AddTokenToHeader(this HttpClient cl, string token)
{
//int timeoutSec = 90;
//cl.Timeout = new TimeSpan(0, 0, timeoutSec);
string contentType = "application/json";
cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(contentType));
cl.DefaultRequestHeaders.Add("Authorization", String.Format("Bearer {0}", token));
var userAgent = "d-fens HttpClient";
cl.DefaultRequestHeaders.Add("User-Agent", userAgent);
return cl;
}
}
And use:
string _tokenUpdated = "TOKEN";
HttpClient _client;
_client.AddTokenToHeader(_tokenUpdated).GetAsync("/api/values")
Use the .NET ServiceController class to start it, or issue the commandline command to start it --- "net start servicename". Either way works.
I think you need something like this....
b="HELLO,THERE,WORLD"
re.findall('[\w]+',b)
Which in Python3 will return
['HELLO', 'THERE', 'WORLD']
Edit To reflect what @Marc said in the comment below.
You can do a loop through all the posted values.
HTML:
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
PHP:
foreach($_POST['check_list'] as $item){
// query to delete where item = $item
}
Trigger
and Sequence
can be used when you want serialized number that anyone can easily read/remember/understand. But if you don't want to manage ID Column (like emp_id) by this way, and value of this column is not much considerable, you can use SYS_GUID()
at Table Creation to get Auto Increment like this.
CREATE TABLE <table_name>
(emp_id RAW(16) DEFAULT SYS_GUID() PRIMARY KEY,
name VARCHAR2(30));
Now your emp_id
column will accept "globally unique identifier value".
you can insert value in table by ignoring emp_id column like this.
INSERT INTO <table_name> (name) VALUES ('name value');
So, it will insert unique value to your emp_id
Column.
The most efficient way:
//Note destroys the original string by removing it's last char
// Do not pass in a string literal.
char * getAllButFirstAndLast(char *input)
{
int len = strlen(input);
if(len > 0)
input++;//Go past the first char
if(len > 1)
input[len - 2] = '\0';//Replace the last char with a null termination
return input;
}
//...
//Call it like so
char str[512];
strcpy(str, "hello world");
char *pMod = getAllButFirstAndLast(str);
The safest way:
void getAllButFirstAndLast(const char *input, char *output)
{
int len = strlen(input);
if(len > 0)
strcpy(output, ++input);
if(len > 1)
output[len - 2] = '\0';
}
//...
//Call it like so
char mod[512];
getAllButFirstAndLast("hello world", mod);
The second way is less efficient but it is safer because you can pass in string literals into input. You could also use strdup for the second way if you didn't want to implement it yourself.
This is expected.
Refer to Javadocs for split
.
Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split(java.lang.String,int) method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
Please note that increasing the Java heap size following an java.lang.OutOfMemoryError: Java heap space is quite often just a short term solution.
This means that even if you increase the default Java heap size from 512 MB to let's say 2048 MB, you may still get this error at some point if you are dealing with a memory leak. The main question to ask is why are you getting this OOM error at the first place? Is it really a Xmx value too low or just a symptom of another problem?
When developing a Java application, it is always crucial to understand its static and dynamic memory footprint requirement early on, this will help prevent complex OOM problems later on. Proper sizing of JVM Xms & Xmx settings can be achieved via proper application profiling and load testing.

We often want to get more information when there is an exception. The following configuration has two targets, a file and the console, which filter on whether or not there is any exception info. (EDIT: Jarek has posted about a new method of doing this in vNext.)
The key is to have a wrapper target with xsi:type="FilteringWrapper" condition="length('${exception}')>0"
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.mono2.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
internalLogLevel="Warn"
internalLogFile="nlog log.log"

I'm rusty on SQL but I think you could use select as to make your own temporary query columns.
select field1, field2, 'example' as newfield from table1
That would only exist in your query results, of course. You're not actually modifying the table.
This works too:
System.DateTime dTime = DateTime.Now();
// tSpan is 0 days, 1 hours, 30 minutes and 0 second.
System.TimeSpan tSpan = new System.TimeSpan(0, 1, 3, 0);
System.DateTime result = dTime + tSpan;
To subtract a year:
DateTime DateEnd = DateTime.Now;
DateTime DateStart = DateEnd - new TimeSpan(365, 0, 0, 0);
here is the solution:
#wrapper {
width: 500px;
border: 1px solid black;
overflow: auto; /* so the size of the wrapper is alway the size of the longest content */
}
#first {
float: left;
width: 300px;
border: 1px solid red;
}
#second {
border: 1px solid green;
margin: 0 0 0 302px; /* considering the border you need to use a margin so the content does not float under the first div*/
}
your demo updated;
If you are only interested in the packages installed globally without the full TREE then:
npm -g ls --depth=0
or locally (omit -g) :
npm ls --depth=0
Just do
NSString* newString=[NSString stringWithFormat:@"first part of string (%@) third part of string", @"foo"];
This gives you
@"first part of string (foo) third part of string"
In case you are working with seaborn plots, instead of Matplotlib, you can save a .png image like this:
Let's suppose you have a matrix
object (either Pandas or NumPy), and you want to take a heatmap:
import seaborn as sb
image = sb.heatmap(matrix) # This gets you the heatmap
image.figure.savefig("C:/Your/Path/ ... /your_image.png") # This saves it
This code is compatible with the latest version of Seaborn. Other code around Stack Overflow worked only for previous versions.
Another way I like is this. I set the size of the next image as follows:
plt.subplots(figsize=(15,15))
And then later I plot the output in the console, from which I can copy-paste it where I want. (Since Seaborn is built on top of Matplotlib, there will not be any problem.)
I don't know how it works with WingIDE, but for using PyLint with Geany, I set my external command to:
PYTHONPATH=${PYTHONPATH}:$(dirname %d) pylint --output-format=parseable --reports=n "%f"
where %f is the filename, and %d is the path. Might be useful for someone :)
<button>
vs.
<input type='button'>

in modern browsers, both elements are easily styleable with css but in most cases, button
element is preferred as you can style more with inner html and pseudo elements
Most of the time you can have Android Studio automatically update the Gradle plugin.
If your Gradle plugin version is behind, Instant Run will mostly likely not work. Therefore if you go to the Instant Run settings (Preferences > Build, Execution, Deployment > Instant Run), you'll see an Update project button at the top right (image below). Clicking this will update both the Gradle wrapper and build tools.
Change the klik method as follows:
public void klik(object pea, EventArgs e)
{
Bitmap c = this.DrawMandel();
Button btn = pea as Button;
Graphics gr = btn.CreateGraphics();
gr.DrawImage(b, 150, 200);
}
In case you want to use the flag "user=Everyone" you need to adjust it to your system language. In english it is as mentioned:
netsh http add urlacl url=http://+:80/ user=Everyone
In german it would be:
netsh http add urlacl url=http://+:80/ user=Jeder
I had the same problem with composer update. But for me it only worked after I cleared the composer cache and after deleting the content of the vendor folder:
rm -rf vendor/*
git gc --prune=now
git pull
composer clear-cache
composer update my/package
Yo can use:
a.update_column :state, a.state
Check: http://apidock.com/rails/ActiveRecord/Persistence/update_column
Updates a single attribute of an object, without calling save.
Use ObjectDataProvider:
<ObjectDataProvider x:Key="enumValues"
MethodName="GetValues" ObjectType="{x:Type System:Enum}">
<ObjectDataProvider.MethodParameters>
<x:Type TypeName="local:ExampleEnum"/>
</ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
and then bind to static resource:
ItemsSource="{Binding Source={StaticResource enumValues}}"
based on this article
As a not yet fully standardized solution (though in alignment with the color syntax in CSS3) you can use e.g fill="rgba(124,240,10,0.5)"
. Works fine in Firefox, Opera, Chrome.
if(!$('#select-box').find("option:contains('" + thevalue + "')").length){_x000D_
//do stuff_x000D_
}

You will need to either use the lower level $.ajax call, or the ajaxError function. Here it is with the $.ajax method:
function update() {
$.ajax({
type: 'GET',
dataType: 'json',
url: url,
timeout: 5000,
success: function(data, textStatus ){
alert('request successful');
},
fail: function(xhr, textStatus, errorThrown){
alert('request failed');
}
});
}
EDIT I added a timeout
to the $.ajax
call and set it to five seconds.
set month you need to date and then set the day to zero ,so month begin in 1 - 31 in date function then get the last day^^
var last = new Date(new Date(new Date().setMonth(7)).setDate(0)).getDate();_x000D_
console.log(last);
_x000D_
I know that this is too late but here is my approach:
<GridViewColumn x:Name="GridHeaderLocalSize" Width="100">
<GridViewColumn.Header>
<GridViewColumnHeader HorizontalContentAlignment="Right">
<Grid Width="Auto" HorizontalAlignment="Right">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Local size" TextAlignment="Right" Padding="0,0,5,0"/>
</Grid>
</GridViewColumnHeader>
</GridViewColumn.Header>
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Width="{Binding ElementName=GridHeaderLocalSize, Path=Width, FallbackValue=100}" HorizontalAlignment="Right" TextAlignment="Right" Padding="0,0,5,0" Text="Text" >
</TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
The main idea is to bind the width of the cellTemplete element to the width of the ViewGridColumn. Width=100 is default width used until first resize. There isn't any code behind. Everything is in xaml.
Another approach if you want to use a varying portion of the dataset instead of a single value is to use rollapply(data, width, FUN, ...)
. Using a vector of widths allows you to apply a function on a varying window of the dataset. I've used this to build an adaptive filtering routine, though it isn't very efficient.
calculate distance in Mysql
SELECT (6371 * acos(cos(radians(lat2)) * cos(radians(lat1) ) * cos(radians(long1) -radians(long2)) + sin(radians(lat2)) * sin(radians(lat1)))) AS distance
thus distance value will be calculated and anyone can apply as required.
Tested in Python 3.3.2 There are many ways to accomplish this, here's one of the shortest, using only python-provided stuff:
import base64
hex_data ='57696C6C20796F7520636F6E76657274207468697320484558205468696E6720696E746F20415343494920666F72206D653F2E202E202E202E506C656565656173652E2E2E212121'
ascii_string = str(base64.b16decode(hex_data))[2:-1]
print (ascii_string)
Of course, if you don't want to import anything, you can always write your own code. Something very basic like this:
ascii_string = ''
x = 0
y = 2
l = len(hex_data)
while y <= l:
ascii_string += chr(int(hex_data[x:y], 16))
x += 2
y += 2
print (ascii_string)
Forget trying to decipher the example .ts - as others have said it is often incomplete.

You can quickly confirm the required modules:
Comment out any instances of ReactiveFormsModule

The reason why you have to modify the AppData could be:
Even after doing that, the latest LTE (4.4.4) still have problem with Windows 10, it worked for a little while then whenever I try to:
$ npm install _some_package_ --global
Node throw the "FATAL ERROR CALL_AND_RETRY_LAST Allocation failed - process out of memory" error. Still try to find a solution to that problem.
The only thing I find works is to run Vagrant or Virtual box, then run the Linux command line (must matching the path) which is quite a messy solution.
I noticed that whenever I would start the form tag inside a div the subsequent div siblings would not be part of the form when I inspect (chrome inspect) henceforth my form would never submit.
<div>
<form>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>
I figured that if I put the form tag outside the DIVs it worked. The form tag should be placed at the start of the parent DIV. Like shown below.
<form>
<div>
<input name='1st input'/>
</div>
<div>
<input name='2nd input'/>
</div>
<input type='submit'/>
</form>

Send a POST request from A. Post requests are on the serverside only and can't be accessed by the client.
You can send a POST request from a.com
to b.com
using CURL (recommended, serverside) or a hidden method="POST"
form (clientside). If you go for the latter, you might want to obfuscate your JavaScript so that the user won't be able to understand the algorithm and interfere with it.
Make a gateway on b.com
to set cookies:
<?php
if (isset($_POST['data']) {
setcookie('a', $_POST['data']);
header("Location: b.com/landingpage");
}
?>
If you want to bring security a step further, implement a function on both sides (a.com
and b.com
) to encrypt (on a.com
) and decrypt (on b.com
) data using a cryptographic cypher.
If you're trying to do something that must be absolutely secure (e.g. transfer a login session) try oAuth or take some inspiration from https://api.cloudianos.com/docs#v2/auth

JUnit 5 now has a @BeforeAll annotation:
Denotes that the annotated method should be executed before all @Test methods in the current class or class hierarchy; analogous to JUnit 4’s @BeforeClass. Such methods must be static.
The lifecycle annotations of JUnit 5 seem to have finally gotten it right! You can guess which annotations available without even looking (e.g. @BeforeEach @AfterAll)
Change <button type="button"
to <button type="submit"
. Remove the onClick
. Instead do <form className="commentForm" onSubmit={this.onFormSubmit}>
. This should catch clicking the button and pressing the return key.
onFormSubmit = e => {
e.preventDefault();
const { name, email } = this.state;
// send to server with e.g. `window.fetch`
}
...
<form onSubmit={this.onFormSubmit}>

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.
to check either a pointer is initialized or not you can try something like
Class *pointer = new Class();
if(pointer!=nullptr){
pointer->myFunction();
}
You are looking for display:
document.getElementById("endTimeLabel").style.display = 'none';
document.getElementById("endTimeLabel").style.display = 'block';
Edit: You could also easily reuse your validation function.

<input id="startDateStr" name="startDateStr" size="8" onchange="if (!formatDate(this,'USA')) {this.value = '';}" />
<button id="startDateCalendarTrigger">...</button>
<input id="startDateTime" type="text" size="8" name="startTime" value="12:00 AM" onchange="validateHHMM(this.value, 'startTimeLabel');"/>
<label id="startTimeLabel" class="errorMsg">Time must be entered in the format HH:MM AM/PM</label><br />
<span id="endDateLabel">End date/time: </span>
<input id="endDateStr" name="endDateStr" size="8" onchange="if (!formatDate(this,'USA')) {this.value = '';}" />
<button id="endDateCalendarTrigger">...</button>
<input id="endDateTime" type="text" size="8" name="endTime" value="12:00 AM" onchange="validateHHMM(this.value, 'endTimeLabel');"/>
<label id="endTimeLabel" class="errorMsg">Time must be entered in the format HH:MM AM/PM</label>
Javascript:
function validateHHMM(value, message) {
var isValid = /^(0?[1-9]|1[012])(:[0-5]\d) [APap][mM]$/.test(value);
if (isValid) {
document.getElementById(message).style.display = "none";
}else {

}
return isValid;

I know this is not really an answer to the question, but I was looking for a way to initialize the DropDownList from a list on the fly in the view when I kept stumbling upon this post.
My mistake was that I tried to create a SelectList from dictionary like this:
//wrong!
@Html.DropDownListFor(m => m.Locality, new SelectList(new Dictionary<string, string>() { { Model.Locality, Model.Locality_text } }, Model.Locality, ...
I then went digging in the official msdn doc, and found that DropDownListFor
doesn't necessarily require a SelectList
, but rather an IEnumerable<SelectListItem>
:
//right
@Html.DropDownListFor(m => m.Locality, new List<SelectListItem>() { new SelectListItem() { Value = Model.Locality, Text = Model.Locality_text, Selected = true } }, Model.Locality, new { @class = "form-control select2ddl" })
In my case I can probably also omit the Model.Locality
as selected item, since its a) the only item and b) it already says it in the SelectListItem.Selected
property.
Just in case you're wondering, the datasource is an AJAX page, that gets dynamically loaded using the SelectWoo/Select2 control.
I found a better library
which transform the normal <select> <option>
to bootsrap button dropdown format.
There are a lot of good answers here already. But for me it was hard to find some example, where the shape or array can break all the program.
So here is the one:
import numpy as np
a = np.array([1,2,3,4])
b = np.array([10,20,30,40])
from sklearn.linear_model import LinearRegression
regr = LinearRegression()
regr.fit(a,b)
This will fail with error:
ValueError: Expected 2D array, got 1D array instead
but if we add reshape
to a
:
a = np.array([1,2,3,4]).reshape(-1,1)
this works correctly!
If the question is how to easily use Eclipse with multiple different workspaces, then you have to use a kludge because shortcuts in OS X do not provide a mechanism for passing command line arguments, for example the "--data" argument that Eclipse takes to specify the workspace. While there may be different reasons to create a duplicate copy of your Eclipse install, doing it for this purpose is, IMNSHO, lame (now you have to maintain multiple eclipse configurations, plugins, etc?).
In any case, here is a workaround. Create the following script in the (single) Eclipse directory (the directory that contains Eclipse.app), and give it a ".command" suffix (e.g. eclipse-workspace2.command) so that you can create an alias from it:
#!/bin/sh
# open, as suggested by Milhous
open -n $(dirname $0)/Eclipse.app --args -data /path/to/your/other/workspace
Now create an alias to that file on your desktop or wherever you want it. You will probably have to repeat this process for each different workspace, but at least it will use the same Eclipse installation.
Try this:
$old_date = Date_create("2010-04-19 18:31:27");
$new_date = Date_format($old_date, "d/m/Y");

Using jQuery you can do:
$(window).width()
$(window).height()
git config --global mergetool.keepBackup false
This should work for Beyond Compare (as mergetool) too
Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage())
;
This is due to the wp_terms
, wp_termmeta
and wp_term_taxonomy
tables, which had all their ID's not set to AUTO_INCREMENT
To do this go to phpmyadmin, click on the concern database, wp_terms
table, click on structure Tab, at right side you will see a tab named A_I(AUTO_INCREMENT)
, check it and save (You are only doing this for the first option, in the case wp_term
you are only doing it for term_id
).
Do the same for wp_termmeta
and wp_term_taxonomy
that will fix the issue.
As you've noticed, the WHERE
clause doesn't allow you to use aggregates in it. That's what the HAVING
clause is for.
HAVING t1.field3=MAX(t1.field3)
Below added code is working for me if you are using pattern dd-MM-yyyy.
public boolean isValidDate(String date) {
boolean check;
String date1 = "^(0?[1-9]|[12][0-9]|3[01])-(0?[1-9]|1[012])-([12][0-9]{3})$";
check = date.matches(date1);
return check;
}
Similar to Etienne's solution, a simple table formats nicely:
| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
Another alternative (which comes with more emphasis), is to make the content the header of a body-less table:
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
|-|-|
Finally, you can include a horizontal line (thematic break) to create a closed box (although the line style is a little different than the header line in the table):
| | |
|-|-|
|`NOTE` | This is something I want you to notice. It has a lot of text, and I want that text to wrap within a cell to the right of the `NOTE`, instead of under it.|
---
Note the empty line after the text.
Install this nuget package from Microsoft System.Net.Http.Json
. It contains extension methods.
Then add using System.Net.Http.Json
Now, you'll be able to see these methods:
So you can now do this:
await httpClient.GetFromJsonAsync<IList<WeatherForecast>>("weatherforecast");
Source: https://www.stevejgordon.co.uk/sending-and-receiving-json-using-httpclient-with-system-net-http-json
You can just loop though the items:
$("input[name^='card']").each(function() {
console.log($(this).val());
});
object.defineProperty
With this, you can easily access cookies
Object.defineProperty(window, "Cookies", {
get: function() {
return document.cookie.split(';').reduce(function(cookies, cookie) {
cookies[cookie.split("=")[0]] = unescape(cookie.split("=")[1]);
return cookies
}, {});
}
});
From now on you can just do:
alert( Cookies.obligations );
This will automatically update too, so if you change a cookie, the Cookies
will change too.
Hyper Text Transfer Protocol (HTTP) is a protocol used for transferring web pages (like the one you're reading right now). A protocol is really nothing but a standard way of doing things. If you were to meet the President of the United States, or the king of a country, there would be specific procedures that you'd have to follow. You couldn't just walk up and say "hey dude". There would be a specific way to walk, to talk, a standard greeting, and a standard way to end the conversation. Protocols in the TCP/IP stack serve the same purpose.
The TCP/IP stack has four layers: Application, Transport, Internet, and Network. At each layer there are different protocols that are used to standardize the flow of information, and each one is a computer program (running on your computer) that's used to format the information into a packet as it's moving down the TCP/IP stack. A packet is a combination of the Application Layer data, the Transport Layer header (TCP or UDP), and the IP layer header (the Network Layer takes the packet and turns it into a frame).
...consists of all applications that use the network to transfer data. It does not care about how the data gets between two points and it knows very little about the status of the network. Applications pass data to the next layer in the TCP/IP stack and then continue to perform other functions until a reply is received. The Application Layer uses host names (like www.dalantech.com) for addressing. Examples of application layer protocols: Hyper Text Transfer Protocol (HTTP -web browsing), Simple Mail Transfer Protocol (SMTP -electronic mail), Domain Name Services (DNS -resolving a host name to an IP address), to name just a few.
The main purpose of the Application Layer is to provide a common command language and syntax between applications that are running on different operating systems -kind of like an interpreter. The data that is sent by an application that uses the network is formatted to conform to one of several set standards. The receiving computer can understand the data that is being sent even if it is running a different operating system than the sender due to the standards that all network applications conform to.
...is responsible for assigning source and destination port numbers to applications. Port numbers are used by the Transport Layer for addressing and they range from 1 to 65,535. Port numbers from 0 to 1023 are called "well known ports". The numbers below 256 are reserved for public (standard) services that run at the Application Layer. Here are a few: 25 for SMTP, 53 for DNS (udp for domain resolution and tcp for zone transfers) , and 80 for HTTP. The port numbers from 256 to 1023 are assigned by the IANA to companies for the applications that they sell.
Port numbers from 1024 to 65,535 are used for client side applications -the web browser you are using to read this page, for example. Windows will only assign port numbers up to 5000 -more than enough port numbers for a Windows based PC. Each application has a unique port number assigned to it by the transport layer so that as data is received by the Transport Layer it knows which application to give the data to. An example is when you have more than one browser window running. Each window is a separate instance of the program that you use to surf the web, and each one has a different port number assigned to it so you can go to www.dalantech.com in one browser window and this site does not load into another browser window. Applications like FireFox that use tabbed windows simply have a unique port number assigned to each tab
...is the "glue" that holds networking together. It permits the sending, receiving, and routing of data.
...consists of your Network Interface Card (NIC) and the cable connected to it. It is the physical medium that is used to transmit and receive data. The Network Layer uses Media Access Control (MAC) addresses, discussed earlier, for addressing. The MAC address is fixed at the time an interface was manufactured and cannot be changed. There are a few exceptions, like DSL routers that allow you to clone the MAC address of the NIC in your PC.

For what it's worth, here is a trim implementation with an eye towards performance. It's much quicker than many other trim routines I've seen around. Instead of using iterators and std::finds, it uses raw c strings and indices. It optimizes the following special cases: size 0 string (do nothing), string with no whitespace to trim (do nothing), string with only trailing whitespace to trim (just resize the string), string that's entirely whitespace (just clear the string). And finally, in the worst case (string with leading whitespace), it does its best to perform an efficient copy construction, performing only 1 copy and then moving that copy in place of the original string.
void TrimString(std::string & str)
{
if(str.empty())
return;
const auto pStr = str.c_str();
size_t front = 0;
while(front < str.length() && std::isspace(int(pStr[front]))) {++front;}
size_t back = str.length();
while(back > front && std::isspace(int(pStr[back-1]))) {--back;}
if(0 == front)
{
if(back < str.length())
{
str.resize(back - front);
}
}
else if(back <= front)
{
str.clear();
}
else
{
str = std::move(std::string(str.begin()+front, str.begin()+back));
}
}

In windows 2008 Server.
i removed ";" in front of extension=php_mbstring.dll in php.ini file and it worked... i followed below link...
Probably the easiest way to do it is to have a php file return JSON. So let's say you have a file query.php
,
$result = mysql_query("SELECT field_name, field_value
FROM the_table");
$to_encode = array();
while($row = mysql_fetch_assoc($result)) {
$to_encode[] = $row;
}
echo json_encode($to_encode);
If you're constrained to using document.write (as you note in the comments below) then give your fields an id attribute like so: <input type="text" id="field1" />
. You can reference that field with this jQuery: $("#field1").val()
.
Here's a complete example with the HTML. If we're assuming your fields are called field1
and field2
, then
<!DOCTYPE html>
<html>
<head>
<title>That's about it</title>
</head>
<body>
<form>
<input type="text" id="field1" />
<input type="text" id="field2" />
</form>
</body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
$.getJSON('data.php', function(data) {
$.each(data, function(fieldName, fieldValue) {
$("#" + fieldName).val(fieldValue);
});
});
</script>
</html>
That's insertion after the HTML has been constructed, which might be easiest. If you mean to populate data while you're dynamically constructing the HTML, then you'd still want the PHP file to return JSON, you would just add it directly into the value
attribute.
C or C++ will not check the bounds of an array access.
You are allocating the array on the stack. Indexing the array via array[3]
is equivalent to *(array + 3)
, where array is a pointer to &array[0]. This will result in undefined behavior.
One way to catch this sometimes in C is to use a static checker, such as splint. If you run:
splint +bounds array.c
on,
int main(void)
{
int array[1];
array[1] = 1;
return 0;
}
then you will get the warning:
array.c: (in function main) array.c:5:9: Likely out-of-bounds store: array[1] Unable to resolve constraint: requires 0 >= 1 needed to satisfy precondition: requires maxSet(array @ array.c:5:9) >= 1 A memory write may write to an address beyond the allocated buffer.
A new byte array will automatically be initialized with all zeroes. You don't have to do anything.
The more general approach to initializing with other values, is to use the Arrays
class.
import java.util.Arrays;
byte[] bytes = new byte[100];
Arrays.fill( bytes, (byte) 1 );
EDIT 2015 May
Disclaimer: I've taken the snippet from the answer linked below:
In addition to WebKit, as of Firefox 35 we'll be able to use the appearance
property:
Using
-moz-appearance
with thenone
value on a combobox now remove the dropdown button
So now in order to hide the default styling, it's as easy as adding the following rules on our select element:
select {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
For IE 11 support, you can use [::-ms-expand
][15].
select::-ms-expand { /* for IE 11 */
display: none;
}

Unfortunately what you ask is not possible by using pure CSS. However, here is something similar that you can choose as a work around. Check the live code below.
div { _x000D_
margin: 10px;_x000D_
padding: 10px; _x000D_
border: 2px solid purple; _x000D_
width: 200px;_x000D_
-webkit-border-radius: 5px;_x000D_
-moz-border-radius: 5px;_x000D_
border-radius: 5px;_x000D_
}_x000D_
div > ul { display: none; }_x000D_
div:hover > ul {display: block; background: #f9f9f9; border-top: 1px solid purple;}_x000D_
div:hover > ul > li { padding: 5px; border-bottom: 1px solid #4f4f4f;}_x000D_
div:hover > ul > li:hover { background: white;}_x000D_
div:hover > ul > li:hover > a { color: red; }
_x000D_
<div>_x000D_
Select_x000D_
<ul>_x000D_
<li><a href="#">Item 1</a></li>_x000D_
<li><a href="#">Item 2</a></li>_x000D_
<li><a href="#">Item 3</a></li>_x000D_
</ul>_x000D_
</div>
_x000D_
EDIT
Here is the question that you asked some time ago. How to style a <select> dropdown with CSS only without JavaScript? As it tells there, only in Chrome and to some extent in Firefox you can achieve what you want. Otherwise, unfortunately, there is no cross browser pure CSS solution for styling a select.
Though there are already many good advice, for my environment(Windows 7, using PowerShell) and the last version available of node.js ( v8.1.2 ) all the above did not worked, except when I followed brunowego settings.
So check your settings with :
npm config list
Settings behind a proxy:
npm config set registry http://registry.npmjs.org/
npm config set http-proxy http://username:password@ip:port
npm config set https-proxy http://username:password@ip:port
npm config set proxy http://username:password@ip:port
npm set strict-ssl false
Hope this will save time to someone
You can also use the logname
command from the BSD General Commands Manual under Linux or MacOS to see the username of the user currently logged in, even if the user is performing a sudo
operation. This is useful, for instance, when modifying a user's crontab while installing a system-wide package with sudo: crontab -u $(logname)
Per man logname
:
LOGNAME(1)
NAME
logname -- display user's login name
First connect to the server and wait for 6 seconds (you can change that) and then execute whatever you need on the remote server using the same tab
tell application "Terminal"
set currentTab to do script ("ssh user@server;")
delay 6
do script ("do something remote") in currentTab
end tell
This is my solution using pure Win32/C++ based on the top answer. The idea is to wrap everything required into one function without the need for external callback functions or structures:
#include <utility>
HWND FindTopWindow(DWORD pid)
{
std::pair<HWND, DWORD> params = { 0, pid };
// Enumerate the windows using a lambda to process each window
BOOL bResult = EnumWindows([](HWND hwnd, LPARAM lParam) -> BOOL
{
auto pParams = (std::pair<HWND, DWORD>*)(lParam);
DWORD processId;
if (GetWindowThreadProcessId(hwnd, &processId) && processId == pParams->second)
{
// Stop enumerating
SetLastError(-1);
pParams->first = hwnd;
return FALSE;
}
// Continue enumerating
return TRUE;
}, (LPARAM)¶ms);
if (!bResult && GetLastError() == -1 && params.first)
{
return params.first;
}
return 0;
}
Query 1: SELECT * FROM yourtable WHERE id > 0 ORDER BY id LIMIT 500
Query 2: SELECT * FROM tbl LIMIT 0,500;
Query 1 run faster with small or medium records, if number of records equal 5,000 or higher, the result are similar.
Result for 500 records:
Query1 take 9.9999904632568 milliseconds
Query2 take 19.999980926514 milliseconds
Result for 8,000 records:
Query1 take 129.99987602234 milliseconds
Query2 take 160.00008583069 milliseconds
[id^='someId']
will match all ids starting with someId
.
[id$='someId']
will match all ids ending with someId
.
[id*='someId']
will match all ids containing someId
.
If you're looking for the name
attribute just substitute id
with name
.
If you're talking about the tag name of the element I don't believe there is a way using querySelector
del array[0]
where 0
is the index of the object in the list (there is no array in python)
My problem was different to any of the above as far as I can tell. I had a working version 1.1 of Android Studio and upgraded to 1.2 Then I got the JAVA_HOME error when starting 1.2
The problem was that my JAVA_HOME was set to "C:\Program Files\Java\jdk1.8.0_20" with quotation marks included. I haven't put them there to quote the string, the quotation marks were in the Variable Value field. It appears that 1.1 is happy with the quotes being there but 1.2 is not.
Removing quotes removed the error and 1.2 now opens fine
as.name(char[1])
will work, although I'm not sure why you'd ever really want to do this -- the quotes won't get carried over in a paste
for example:
> paste("I am counting to", char[1], char[2], char[3])
[1] "I am counting to one two three"
You can try to use this attribute(ConstraintLayout):layout_constraintBaseline_toBaselineOf
Like this:
app:layout_constraintBaseline_toBaselineOf="@+id/textView"
There are three different setups that providing a stack to run an application on (This will help us to recognize what a container is and what makes it so much powerful than other solutions):
1) Traditional Servers(bare metal)
2) Virtual machines (VMs)
3) Containers
1) Traditional server stack consist of a physical server that runs an operating system and your application.
Advantages:
Utilization of raw resources
Isolation
Disadvantages:
2) The VM stack consist of a physical server which runs an operating system and a hypervisor that manages your virtual machine, shared resources, and networking interface. Each Vm runs a Guest Operating System, an application or set of applications.
Advantages:
Disadvantages:
3) The Container Setup, the key difference with other stack is container-based virtualization uses the kernel of the host OS to rum multiple isolated guest instances. These guest instances are called as containers. The host can be either a physical server or VM.
Advantages:
Disadvantages:
By comparing the container setup with its predecessors, we can conclude that containerization is the fastest, most resource effective, and most secure setup we know to date. Containers are isolated instances that run your application. Docker spin up the container in a way, layers get run time memory with default storage drivers(Overlay drivers) those run within seconds and copy-on-write layer created on top of it once we commit into the container, that powers the execution of containers. In case of VM's that will take around a minute to load everything into the virtualize environment. These lightweight instances can be replaced, rebuild, and moved around easily. This allows us to mirror the production and development environment and is tremendous help in CI/CD processes. The advantages containers can provide are so compelling that they're definitely here to stay.
In Chrome, use JSONView to view formatted JSON.
To view "local" *.json files: - after install You must open the Extensions option from Window menu. - Check box next to "Allow Access to File URLs" - note that save is automatic (i.e. no explicit save necessary)
Re-open the *.json file and it should be formatted.
Open .edmx file any text editor change the Schema="your required schema" and also open the app.config/web.config, change the user id and password from the connection string. you are done.
The following script works for me for multiple values of $COLUMNS
. I wonder if you are not setting COLUMNS
prior to this call?
#!/bin/bash
COLUMNS=30
svn diff $@ --diff-cmd /usr/bin/diff -x "-y -w -p -W $COLUMNS"
Can you echo $COLUMNS
inside your script to see if it set correctly?
Here are some more exotic Python 3 ways to get "hello" TAB "alex" (tested with Python 3.6.10):
"hello\N{TAB}alex"
"hello\N{tab}alex"
"hello\N{TaB}alex"
"hello\N{HT}alex"
"hello\N{CHARACTER TABULATION}alex"
"hello\N{HORIZONTAL TABULATION}alex"
"hello\x09alex"
"hello\u0009alex"
"hello\U00000009alex"
Actually, instead of using an escape sequence, it is possible to insert tab symbol directly into the string literal. Here is the code with a tabulation character to copy and try:
"hello alex"
If the tab in the string above won't be lost anywhere during copying the string then "print(repr(< string from above >)" should print 'hello\talex'.
See respective Python documentation for reference.
I was trying to also sort by a DateTime field descending and this seems to do the trick:

If you're using .NET Core 3.0, you can use System.Text.Json (which is now built-in) to deserialize JSON.
The first step is to create classes to model the JSON. There are many tools which can help with this, and some of the answers here list them.
Some options are http://json2csharp.com, http://app.quicktype.io, or use Visual Studio (menu Edit → Paste Special → Paste JSON as classes).
public class Person
{
public string Id { get; set; }
public string Name { get; set; }
}
public class Response
{
public List<Person> Data { get; set; }
}
Then you can deserialize using:
var people = JsonSerializer.Deserialize<Response>(json);
If you need to add settings, such as camelCase
handling, then pass serializer settings into the deserializer like this:
var options = new JsonSerializerOptions() { PropertyNamingPolicy = JsonNamingPolicy.CamelCase };
var person = JsonSerializer.Deserialize<Response>(json, options);
Use assets like a filesystem to dump any kind of files. And use res to store what it is made for, layouts, images, values.
For MAC os user:
I have faced this issue many times. The key here is to set these environment variables before installing mysqlclient by pip command. For my case, they are like below:
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
Most of you are wrong. If you want to close existing activity stack regardless of what's in there and create new root, correct set of flags is the following:
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
public static final int FLAG_ACTIVITY_CLEAR_TASK
Added in API level 11If set in an Intent passed to
Context.startActivity()
, this flag will cause any existing task that would be associated with the activity to be cleared before the activity is started. That is, the activity becomes the new root of an otherwise empty task, and any old activities are finished. This can only be used in conjunction withFLAG_ACTIVITY_NEW_TASK
.
java.lang.String.split(String regex)
is what you are looking for.
Using requests and json makes it simple.
json.loads
functionRequests module provides you useful function to loop for success and failure.
if(Response.ok)
: will help help you determine if your API call is successful (Response code - 200)
Response.raise_for_status()
will help you fetch the http code that is returned from the API.
Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.
#Python 2.7.6
#RestfulClient.py
import requests
from requests.auth import HTTPDigestAuth
import json
# Replace with the correct URL
url = "http://api_url"
# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)
# For successful API call, response code will be 200 (OK)
if(myResponse.ok):
# Loading the response data into a dict variable
# json.loads takes in only binary or string variables so using content to fetch binary content

You can use this tr and td parameter also.
there are two way:
First :
Inside your CD
of SQL Server 2012
you can go to this path \redist\VisualStudioShell
.
And you most install this file VS10sp1-KB983509.msp
.
After several minutes your problem fix.
Restart your computer and then fire SetUp
of SQL Server 2012
.
See this picture.
Secound :
But if you want download online Service Pack 1
view This Link
And press download.
After download run this exe file and let it download and fix your VS2010 to VS2010 SP1.
And then restart your windows.
After this operation you can install SQL Server 2012
Call member function on string command
#include <iostream>
#include <string>
class A
{
public:
void call();
private:
void printH();
void command(std::string a, std::string b, void (A::*func)());
};
void A::printH()
{
std::cout<< "H\n";
}
void A::call()
{
command("a","a", &A::printH);
}
void A::command(std::string a, std::string b, void (A::*func)())
{
if(a == b)
{
(this->*func)();
}
}
int main()
{
A a;
a.call();
return 0;
}
Pay attention to (this->*func)();
and the way to declare the function pointer with class name void (A::*func)()
Try to add auth method explicitly as below, because sometimes it is required:
session.setConfig("PreferredAuthentications", "password");
Windows Server 2003 and later (i.e. anything after Windows XP 32 bit) provide the where.exe
program which does some of what which
does, though it matches all types of files, not just executable commands. (It does not match built-in shell commands like cd
.) It will even accept wildcards, so where nt*
finds all files in your %PATH%
and current directory whose names start with nt
.
Try where /?
for help.
Note that Windows PowerShell defines where
as an alias for the Where-Object
cmdlet, so if you want where.exe
, you need to type the full name instead of omitting the .exe
extension.
Quick/Easy Fix:
Use JQuery .toggle() to show/hide the rows onclick of either Row or an Anchor.
A function will need to be written to identify the rows you would like hidden, but toggle creates the functionality you are looking for.
I did it like this, a variation on Vadims code but to me a bit more readable:
' Returns TRUE if item is already contained in collection, otherwise FALSE
Public Function Contains(col As Collection, item As String) As Boolean
Dim i As Integer
For i = 1 To col.Count
If col.item(i) = item Then
Contains = True
Exit Function
End If
Next i
Contains = False
End Function
some data structures are missing from the standard java collections.
Bag (like set but can contain elements multiple times)
UniqueList (ordered list, can contain each element only once)
seems you would need a uniquelist in this case
if you need flexible data structures, you might be interested in Google Collections
$(".element").select2(/*Your code*/)
.on('change', function (e) {
var getID = $(this).select2('data');
alert(getID[0]['id']); // That's the selected ID :)
});
With jQuery:
$.browser
gives you somthing like:
Object {chrome: true, version: "26.0.1410.63", webkit: true}
You should know that it is not possible to directly run a DDL statement like you do for DML from a PL/SQL block because PL/SQL does not support late binding directly it only support compile time binding which is fine for DML. hence to overcome this type of problem oracle has provided a dynamic SQL approach which can be used to execute the DDL statements.The dynamic sql approach is about parsing and binding of sql string at the runtime. Also you should rememder that DDL statements are by default auto commit hence you should be careful about any of the DDL statement using the dynamic SQL approach incase if you have some DML (which needs to be commited explicitly using TCL) before executing the DDL in the stored proc/function.
You can use any of the following dynamic sql approach to execute a DDL statement from a pl/sql block.
1) Execute immediate
2) DBMS_SQL package
3) DBMS_UTILITY.EXEC_DDL_STATEMENT (parse_string IN VARCHAR2);
Hope this answers your question with explanation.
As taken from the #jquery Freenode IRC channel:
$.each($(form).serializeArray(), function(_, field) { /* use field.name, field.value */ });
Thanks to @Cork on the channel.
you can simply use rstrip:
for stuff in largestring:
print(stuff.rstrip("\n")
If you are using a zsh terminal you're able to use wildcard magic:
sed -i "" "s/search/high-replace/g" *.txt
The command setwd("~/")
should set your working directory to your home directory. You might be experiencing problems because the OS you are using does not recognise "~/"
as your home directory: this might be because of the OS, or it might be because of not having set that as your home directory elsewhere.
As you have tagged the post using RStudio:
You will now have set the folder as your working directory. Use the command getwd()
to get the working directory as it is now set, and save that as a variable string at the top of your script. Then use setwd
with that string as the argument, so that each time you run the script you use the same directory.
For example at the top of my script I would have:
work_dir <- "C:/Users/john.smith/Documents"
setwd(work_dir)
I tried all the above answers and the only version who works for me is the jquery 1.11.1. I tried with all the other versions 1.3.2, 1.4.4, 1.8.2, 3.3.1 and navbar dropdown doesn't work.
<script src="jquery/jquery-1.11.1.min.js"></script>
November 2019:
onclick="self.close()"
still works in Chrome while Edge gives a warning that must be confirmed before it will close.
On the other hand the solution onclick="window.open('', '_self', ''); window.close();"
works in both.
Sometimes if you use JavaScript the DocumentComplete
event don't return the right answer; I use the event ProgressChanged
instead:
Private Sub WebBrowser1_ProgressChanged(sender As Object, e As WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged
Console.WriteLine("Current Progress: " + e.CurrentProgress.ToString)
If e.CurrentProgress = e.MaximumProgress Then
' The maximum progress is reached
load_started = True
End If
' The page is confirmed downloaded after the progress returns to 0
If e.CurrentProgress = 0 Then
If load_started Then
' The page is ready to print or download...
WebBrowser1.Print()
load_started = False
End If
End If
End Sub
Three options:
Create the new database, bring down the server, move the files from one database folder to the other, and restart the server. Note that this will only work if ALL of your tables are MyISAM.
Create the new database, use CREATE TABLE ... LIKE statements, and then use INSERT ... SELECT * FROM statements.
Use mysqldump and reload with that file.
If you are using maven your pom's <dependencies>
tag should look like:

It works for me.
Trident provides the ::-ms-check
pseudo-element for checkbox and radio button controls. For example:
<input type="checkbox">
<input type="radio">
::-ms-check {
color: red;
background: black;
padding: 1em;
}
This displays as follows in IE10 on Windows 8:
I had the same problem after a MacOS system upgrade. Solved it by upgrading the postgres with brew. Details: it looks like the system was trying to access Postgres 11 using older Postgres 10 settings. I'm sure it was my mistake somewhere in the past, but luckily it all got sorted out with the upgrade above.
Instance variable is the variable declared inside a class, but outside a method: something like:
class IronMan {
/** These are all instance variables **/
public String realName;
public String[] superPowers;
public int age;
/** Getters and setters here **/
}
Now this IronMan Class can be instantiated in another class to use these variables. Something like:
class Avengers {
public static void main(String[] a) {
IronMan ironman = new IronMan();
ironman.realName = "Tony Stark";
// or
ironman.setAge(30);
}
}
This is how we use the instance variables. Shameless plug: This example was pulled from this free e-book here here.
With the cursor on the class name declaration I do ALT + Return and my Intellij 14.1.4 offers me a popup with the option to 'Create Test'.
In Visual Studio 2010, if you type "ctor" (without the quotes), IntelliSense should load, showing you "ctor" in the list. Now press TAB twice, and you should have generated an empty constructor.
The accepted answer is not perfect. The line that was printed first will stay there and if your second print does not cover the entire new line, you will end up with garbage text.
To illustrate the problem save this code as a script and run it (or just take a look):
import time
n = 100
for i in range(100):
for j in range(100):
print("Progress {:2.1%}".format(j / 100), end="\r")
time.sleep(0.01)
print("Progress {:2.1%}".format(i / 100))
The output will look something like this:
Progress 0.0%%
Progress 1.0%%
Progress 2.0%%
Progress 3.0%%
What works for me is to clear the line before leaving a permanent print. Feel free to adjust to your specific problem:
import time
ERASE_LINE = '\x1b[2K' # erase line command
n = 100
for i in range(100):
for j in range(100):
print("Progress {:2.1%}".format(j / 100), end="\r")
time.sleep(0.01)
print(ERASE_LINE + "Progress {:2.1%}".format(i / 100)) # clear the line first
And now it prints as expected:
Progress 0.0%
Progress 1.0%
Progress 2.0%
Progress 3.0%
SQLiteDatabase sqldb = MyProvider.db;

Just put the desired logic in the constructor of the request scoped bean associated with the JSF page.
public Bean() {
// Do your stuff here.
}
Use @PostConstruct
annotated method on a request or view scoped bean. It will be executed after construction and initialization/setting of all managed properties and injected dependencies.
@PostConstruct
public void init() {
// Do your stuff here.
}
This is strongly recommended over constructor in case you're using a bean management framework which uses proxies, such as CDI, because the constructor may not be called at the times you'd expect it.
Alternatively, use <f:event type="preRenderView">
in case you intend to initialize based on <f:viewParam>
too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct
is perfectly fine too.
<f:metadata>
<f:viewParam name="foo" value="#{bean.foo}" />
<f:event type="preRenderView" listener="#{bean.onload}" />
</f:metadata>
public void onload() {
// Do your stuff here.
}
Alternatively, use <f:viewAction>
in case you intend to initialize based on <f:viewParam>
too, or when the bean is put in a broader scope than the view scope (which in turn indicates a design problem, but that aside). Otherwise, a @PostConstruct
is perfectly fine too.
<f:metadata>
<f:viewParam name="foo" value="#{bean.foo}" />
<f:viewAction action="#{bean.onload}" />
</f:metadata>
public void onload() {
// Do your stuff here.
}
Note that this can return a String
navigation case if necessary. It will be interpreted as a redirect (so you do not need a ?faces-redirect=true
here).
public String onload() {
// Do your stuff here.
// ...
return "some.xhtml";
}
load
event, not during page load.I think what you originally meant to do was to make an array only of characters, not of pointers:
char options[2][100];
options[0][0]='t';
options[0][1]='e';
options[0][2]='s';
options[0][3]='t';
options[0][4]='1';
options[0][5]='\0'; /* NUL termination of C string */
/* A standard C library function which copies strings. */
strcpy(options[1], "test2");
The code above shows two distinct methods of setting the character values in memory you have set aside to contain characters.
I was also searching same answer, because at some point of time I needed total_count with distinct values along with limit/offset.
Because it's little tricky to do- To get total count with distinct values along with limit/offset. Usually it's hard to get total count with limit/offset. Finally I got the way to do -
SELECT DISTINCT COUNT(*) OVER() as total_count, * FROM table_name limit 2 offset 0;
Query performance is also high.
Almost 2 years later....
This github project readme has a some clarity of configuration of the maven plugin and it seems, according to this apache github project, the plugin itself will materialise soon enough.
The following works for me:
git diff master:foo foo
In the past, it may have been:
git diff foo master:foo
There is a new annotation @Value
in Spring 3.0.0M3. @Value
support not only #{...}
expressions but ${...}
placeholders as well
You can also add hash when page is loading:
location.hash = "noBack";
Then just handle location hash change to add another hash:
$(window).on('hashchange', function() {
location.hash = "noBack";
});
That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.
ElementTree is a good module for reading xml and writing too e.g.
from xml.etree.ElementTree import Element, SubElement, tostring
root = Element('root')
child = SubElement(root, "child")
child.text = "I am a child"
print(tostring(root))
Output:
<root><child>I am a child</child></root>
See this tutorial for more details and how to pretty print.
Alternatively if your XML is simple, do not underestimate the power of string formatting :)
xmlTemplate = """<root>
<person>
<name>%(name)s</name>
<address>%(address)s</address>
</person>
</root>"""
data = {'name':'anurag', 'address':'Pune, india'}
print xmlTemplate%data
Output:
<root>
<person>
<name>anurag</name>
<address>Pune, india</address>
</person>
</root>
You can use string.Template or some template engine too, for complex formatting.
You can see value inside [object Object] like this
Alert.alert( JSON.stringify(userDate) );
Try like this
realm.write(() => {
const userFormData = realm.create('User',{
user_email: value.username,
user_password: value.password,
});
});
const userDate = realm.objects('User').filtered('user_email == $0', value.username.toString(), );
Alert.alert( JSON.stringify(userDate) );
reference
$past = time() - 3600;
foreach ( $_COOKIE as $key => $value )
{
setcookie( $key, $value, $past, '/' );
}
Even better is however to remember (or store it somewhere) which cookies are set with your application on a domain and delete all those directly.
That way you can be sure to delete all values correctly.
Your code will give you an exception when you reach the end of the iterator. You could do:
int i = 0;
while(iterator.hasNext()) {
i++;
iterator.next();
}
If you had access to the underlying collection, you would be able to call coll.size()
...
EDIT OK you have amended...
For those of us who prefer jQuery, you would use the form plugin: http://plugins.jquery.com/project/form, which contains a formSerialize method.
Use /bin/sh
. Create a small shell script that sets the variables, and then parse the template using the shell itself. Like so (edit to handle newlines correctly):
the number is ${i}
the word is ${word}
#!/bin/sh
#Set variables
i=1
word="dog"
#Read in template one line at the time, and replace variables (more
#natural (and efficient) way, thanks to Jonathan Leffler).
while read line
do
eval echo "$line"
done < "./template.txt"
#sh script.sh
the number is 1
the word is dog
Nope, Model window needs to be handle by javaScriptExecutor,Because majorly model window made up of window model, This will works once model appeared then control take a place into model and click the expected element.
have to import javascriptexector
like below,
Javascriptexecutor js =(Javascriptexecutor).driver;
js.executescript(**<element to be clicked>**);
I used Rafid's suggestion of using AJAX.
This worked for me:
var url = "http://www.example.com/file.json";
var jsonFile = new XMLHttpRequest();
jsonFile.open("GET",url,true);
jsonFile.send();
jsonFile.onreadystatechange = function() {
if (jsonFile.readyState== 4 && jsonFile.status == 200) {
document.getElementById("id-of-element").innerHTML = jsonFile.responseText;
}
}
I basically(almost literally) copied this code from http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_get2 so credit to them for everything.
I dont have much knowledge of how this works but you don't have to know how your brakes work to use them ;)
Hope this helps!
Another option would be to use the File Explorer in DDMS (Eclipse SDK), you can see the whole file system there and download/upload files to the desired place. That way you don't have to mount and deal with images. Just remember to set your device as USB debuggable (from Developer Tools)
Try SuperPuTTY. It is similar to puttycm.
look also hier:

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.
After some googling I found this link:
The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged
So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.
I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)
It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):
Dim d As dictionary
Set d = New dictionary
d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection
You can also use the VBA Collection object if your needs are simpler and you just want string keys.
I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)
This is just an explanation not addressed in other answers
At least in recent versions of Mysql, your first query is not committed.
If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.
What's going on?
When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.
So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE
, UPDATE
, INSERT
or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT
) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).
That's why the solution involves declaring handlers to immediately ROLLBACK
when an error happens.
Extra
Inside the handler you can also re-raise the error using RESIGNAL
, otherwise the stored procedure executes "Successfully"
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK;
RESIGNAL;
END;
START TRANSACTION;
#.. Query 1 ..
#.. Query 2 ..
#.. Query 3 ..
COMMIT;
END
What he wants to say is:
"If you have two classes which share most of the same properties you can cast an object from class a
to class b
and automatically make the system understand the assignment via the shared property names?"
Option 1: Use reflection
Disadvantage : It's gonna slow you down more than you think.
Option 2: Make one class derive from another, the first one with common properties and other an extension of that.
Disadvantage: Coupled! if your're doing that for two layers in your application then the two layers will be coupled!
Let there be:
class customer
{
public string firstname { get; set; }
public string lastname { get; set; }
public int age { get; set; }
}
class employee
{
public string firstname { get; set; }
public int age { get; set; }
}
Now here is an extension for Object type:
public static T Cast<T>(this Object myobj)
{
Type objectType = myobj.GetType();
Type target = typeof(T);
var x = Activator.CreateInstance(target, false);
var z = from source in objectType.GetMembers().ToList()
where source.MemberType == MemberTypes.Property select source ;
var d = from source in target.GetMembers().ToList()
where source.MemberType == MemberTypes.Property select source;
List<MemberInfo> members = d.Where(memberInfo => d.Select(c => c.Name)
.ToList().Contains(memberInfo.Name)).ToList();
PropertyInfo propertyInfo;
object value;
foreach (var memberInfo in members)
{
propertyInfo = typeof(T).GetProperty(memberInfo.Name);
value = myobj.GetType().GetProperty(memberInfo.Name).GetValue(myobj,null);
propertyInfo.SetValue(x,value,null);
}
return (T)x;
}
Now you use it like this:
static void Main(string[] args)
{
var cus = new customer();
cus.firstname = "John";
cus.age = 3;
employee emp = cus.Cast<employee>();
}
Method cast checks common properties between two objects and does the assignment automatically.
This is one of the reasons I try to avoid using MS Server... but anyway. Sometimes you just don't have an option (yei! and I have to use an outdated version!!).
My suggestion is to create a virtual table:
From:
SELECT * FROM table
To:
CREATE VIEW v_table AS
SELECT ROW_NUMBER() OVER (ORDER BY table_key) AS row,* FROM table
Then just query:
SELECT * FROM v_table WHERE row BETWEEN 10 AND 20
If fields are added, or removed, "row" is updated automatically.
The main problem with this option is that ORDER BY is fixed. So if you want a different order, you would have to create another view.
UPDATE
There is another problem with this approach: if you try to filter your data, it won't work as expected. For example, if you do:
SELECT * FROM v_table WHERE field = 'test' AND row BETWEEN 10 AND 20
WHERE becomes limited to those data which are in the rows between 10 and 20 (instead of searching the whole dataset and limiting the output).
It would be easier to recreate the data frame. This would also interpret the columns types from scratch.
headers = df.iloc[0]
new_df = pd.DataFrame(df.values[1:], columns=headers)
I upgraded to my Git for Windows to latest (2.30.0) 64-bit and it works fine now. get the latest from the url https://git-scm.com/download/win and run the commands below to verify. $ git --version $ git version 2.30.0.windows.1
In Spark 2.0 a CSV reader is build into Spark, so you can easily load a CSV file as follows:
spark.read.option("header","true").csv("filePath")
Another thing that people may find useful when using the develop
method is the --user
option to install without sudo. Ex:
python setup.py develop --user
instead of
sudo python setup.py develop

A bit more elegant to my taste is to create a random column and then split by it, this way we can get a split that will suit our needs and will be random.
def split_df(df, p=[0.8, 0.2]):
import numpy as np
df["rand"]=np.random.choice(len(p), len(df), p=p)
r = [df[df["rand"]==val] for val in df["rand"].unique()]
return r
Since dates correspond to a numeric value and a starting date, you indeed need the day. If you really need your data to be in Date format, you can just fix the day to the first of each month manually by pasting it to the date:
month <- "2009-03"
as.Date(paste(month,"-01",sep=""))
It works for Bootstrap v3.3.6
$('#dialog').modal()
.on('hide.bs.modal', function () {
// Some Code

// Some Code
}).on('hidden.bs.modal', function () {
$("#dialog").off();
});
You can text-align: center the body to center the container. Then text-align: left the container to get all the text, etc. to align left.

If none of the above answers worked for you, You can try the following solution which worked for me.
Go to Services manager(services.msc) and enable the below services and try again.
- WLAN AutoConfig
- Wi-Fi Direct Services Connection Manager Service
Hope this solved your problem.
It takes two numbers from the user, feeds them to the function called add
(in the very last line of the code), and add
will sum them up and print them.
#!/bin/bash
read -p "Enter the first value: " x
read -p "Enter the second value: " y
add(){
arg1=$1 # arg1 gets to be the first assigned argument (note there are no spaces)
arg2=$2 # arg2 gets to be the second assigned argument (note there are no spaces)
echo $(($arg1 + $arg2))
}
add x y # Feeding the arguments
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager Nmang = (NotificationManager) getApplicationContext()

You can use strsplit
and sapply
functions
sapply(strsplit(str1, " "), length)
What does it mean to "unwrap the instance"? Why is it necessary?
As far as I can work out (this is very new to me, too)...
The term "wrapped" implies we should think of an Optional variable as a present, wrapped in shiny paper, which might (sadly!) be empty.
When "wrapped", the value of an Optional variable is an enum with two possible values (a little like a Boolean). This enum describes whether the variable holds a value (Some(T)
), or not (None
).
If there is a value, this can be obtained by "unwrapping" the variable (obtaining the T
from Some(T)
).
How is
john!.apartment = number73
different fromjohn.apartment = number73
? (Paraphrased)
If you write the name of an Optional variable (eg text john
, without the !
), this refers to the "wrapped" enum (Some/None), not the value itself (T). So john
isn't an instance of Person
, and it doesn't have an apartment
member:
john.apartment
// 'Person?' does not have a member named 'apartment'
The actual Person
value can be unwrapped in various ways:
john!
(gives the Person
value if it exists, runtime error if it is nil)if let p = john { println(p) }
(executes the println
if the value exists)john?.learnAboutSwift()
(executes this made-up method if the value exists)I guess you choose one of these ways to unwrap, depending upon what should happen in the nil case, and how likely that is. This language design forces the nil case to be handled explicitly, which I suppose improves safety over Obj-C (where it is easy to forget to handle the nil case).
Update:
The exclamation mark is also used in the syntax for declaring "Implicitly Unwrapped Optionals".
In the examples so far, the john
variable has been declared as var john:Person?
, and it is an Optional. If you want the actual value of that variable, you must unwrap it, using one of the three methods above.
If it were declared as var john:Person!
instead, the variable would be an Implicitly Unwrapped Optional (see the section with this heading in Apple's book). There is no need to unwrap this kind of variable when accessing the value, and john
can be used without additional syntax. But Apple's book says:
Implicitly unwrapped optionals should not be used when there is a possibility of a variable becoming nil at a later point. Always use a normal optional type if you need to check for a nil value during the lifetime of a variable.
Update 2:
The article "Interesting Swift Features" by Mike Ash gives some motivation for optional types. I think it is great, clear writing.
Update 3:
Another useful article about the implicitly unwrapped optional use for the exclamation mark: "Swift and the Last Mile" by Chris Adamson. The article explains that this is a pragmatic measure by Apple used to declare the types used by their Objective-C frameworks which might contain nil. Declaring a type as optional (using ?
) or implicitly unwrapped (using !
) is "a tradeoff between safety and convenience". In the examples given in the article, Apple have chosen to declare the types as implicitly unwrapped, making the calling code more convenient, but less safe.
Perhaps Apple might comb through their frameworks in the future, removing the uncertainty of implicitly unwrapped ("probably never nil") parameters and replacing them with optional ("certainly could be nil in particular [hopefully, documented!] circumstances") or standard non-optional ("is never nil") declarations, based on the exact behaviour of their Objective-C code.
The following should work in an angular CLI 6 project. I.e if you are getting:
get/set have been deprecated in favor of the config command.
npm install node-sass --save-dev
Then (making sure you change the project name)
ng config projects.YourPorjectName.schematics.@schematics/angular:component.styleext sass
To get your default project name use:
ng config defaultProject
However: If you have migrated your project from <6 up to angular 6 there is a good chance that the config wont be there. In which case you might get:
Invalid JSON character: "s" at 0:0
Therefore a manual editing of angular.json
will be required.
You will want it to look something like this (taking note of the styleex property):
...
"projects": {
"Sassy": {
"root": "",
"sourceRoot": "src",
"projectType": "application",
"prefix": "app",
"schematics": {
"@schematics/angular:component": {
"styleext": "scss"
}
}
...
Seems like an overly complex schema to me. ¯_(?)_/¯
You will now have to go and change all your css/less files to be scss and update any references in components etc, but you should be good to go.
Use this code it works perfectly for odd or even list sizes. Hope it help somebody .
int listSize = listOfArtist.size();
int mid = 0;
if (listSize % 2 == 0) {
mid = listSize / 2;
Log.e("Parting", "You entered an even number. mid " + mid
+ " size is " + listSize);
} else {
mid = (listSize + 1) / 2;
Log.e("Parting", "You entered an odd number. mid " + mid
+ " size is " + listSize);
}
//sublist returns List convert it into arraylist * very important
leftArray = new ArrayList<ArtistModel>(listOfArtist.subList(0, mid));
rightArray = new ArrayList<ArtistModel>(listOfArtist.subList(mid,
listSize));
getdate()
is the direct equivalent, but you should always use UTC datetimes
getutcdate()
whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions
As Thomas Owens pointed out, simply concatenating the files will leave multiple ID3 headers scattered throughout the resulting concatenated file - so the time/bitrate info will be wildly wrong.
You're going to need to use a tool which can combine the audio data for you.
mp3wrap would be ideal for this - it's designed to join together MP3 files, without needing to decode + re-encode the data (which would result in a loss of audio quality) and will also deal with the ID3 tags intelligently.
The resulting file can also be split back into its component parts using the mp3splt tool - mp3wrap adds information to the IDv3 comment to allow this.
Here is the full code, it's working from my side: just test.

You can try using the ReadDir function in the io/ioutil
package. Per the docs:
ReadDir reads the directory named by dirname and returns a list of sorted directory entries.
The resulting slice contains os.FileInfo
types, which provide the methods listed here. Here is a basic example that lists the name of everything in the current directory (folders are included but not specially marked - you can check if an item is a folder by using the IsDir()
method):
package main
import (
"fmt"
"io/ioutil"
"log"
)
func main() {
files, err := ioutil.ReadDir("./")
if err != nil {
log.Fatal(err)
}
for _, f := range files {
fmt.Println(f.Name())
}
}
def GetShiftingWindows(thelist, size):

[ [1, 2, 3], [2, 3, 4], [3, 4, 5] ]

Yes. There is an HTTP plugin for MySQL.
http://blog.ulf-wendel.de/2014/mysql-5-7-http-plugin-mysql/
I'm just googling about it now, which led me to this stackoverflow question. You should be able to AJAX a MySQL database now or in the near future (they claim it's not ready for production).
Lots of answers but no substance, like robots doing cut and paste on what's on their system. There is no need to set GOROOT
as an environment variable. However, there is a beneficial need to set the GOPATH
environment variable, and if not set it defaults to ${HOME}/go/
folder.
It is the PATH
environment variable that you must pay attention because this variable is the variable that can change your go version
. Not GOROOT
! Forget GOROOT
.
Now, if you switch or change to a new go version
, your downloaded packages will use the default $HOME/go
folder and it will mixed-up with whatever your previous go version
was. This is not good.
Therefore, this is where GOPATH
you need to define in order to isolate downloaded packages of the new go version
.
In summary, forget GOROOT
. Think more on GOPATH
.
Some shortcut is to create a NumberFormatInfo class, set its NumberDecimalSeparator property to "." and use the class as parameter to ToString() method whenever u need it.
using System.Globalization;
NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ".";
value.ToString(nfi);
I recommend the following for Bootstrap 3
.carousel-inner > .item > img,
.carousel-inner > .item > a > img {
min-height: 500px; /* Set slide height here */
}
Use NULL. NULL shows your intent. That it is 0 is an implementation detail that should not matter.
xxhdpi was not specified before but now new devices S4, HTC one are surely comes inside xxhdpi .These device dpi are around 440. I do not know exact limit for xxhdpi See how to develop android application for xxhdpi device Samsung S4 I know this is late answer but as thing had change since the question asked
Note Google Nexus 10 need to add a 144*144px icon in the drawable-xxhdpi or drawable-480dpi folder.
As I see in your code, it seems you are following an old documentation/tutorial about OOP in PHP based on PHP4 (OOP wasn't supported but adapted somehow to be used in a simple ways), since PHP5 an official support was added and the notation has been changed from what it was.
Please see this code review here:
<?php
class my_class{
public $my_value = array();
function __construct( $value ) { // the constructor name is __construct instead of the class name
$this->my_value[] = $value;
}
function set_value ($value){
// Error occurred from here as Undefined variable: my_value
$this->my_value = $value; // remove the $ sign
}
}
$a = new my_class ('a');
$a->my_value[] = 'b';
$a->set_value ('c'); // your array variable here will be replaced by a simple string
// $a->my_class('d'); // you can call this if you mean calling the contructor
// at this stage you can't loop on the variable since it have been replaced by a simple string ('c')
foreach ($a->my_value as &$value) { // look for foreach samples to know how to use it well
echo $value;
}
?>
I hope it helps
You can use CSS under legend.green-color a:hover
to do it.
legend.green-color a:hover {
color:green;
text-decoration:none;
}
It's good practice to give a parent to your QTimer
to use Qt's memory management system.
update()
is a QWidget function - is that what you are trying to call or not? http://qt-project.org/doc/qt-4.8/qwidget.html#update.
If number 2 does not apply, make sure that the function you are trying to trigger is declared as a slot in the header.
Finally if none of these are your issue, it would be helpful to know if you are getting any run-time connect errors.
For creating real UML class diagrams:
In Visual Studio 2013 Ultimate you can do this without any external tools.
You will have a empty UMLClassDiagram.classdiagram.
Core jQuery doesn't have anything special for touch events, but you can easily build your own using the following events
For example, the touchmove
document.addEventListener('touchmove', function(e) {
e.preventDefault();
var touch = e.touches[0];
alert(touch.pageX + " - " + touch.pageY);
}, false);
This works in most WebKit based browsers (incl. Android).
If u want to add Hello world at the end of each line:
:%s/$/HelloWorld/
If you want to do this for specific number of line say, from 20 to 30 use:
:20,30s/$/HelloWorld/
If u want to do this at start of each line then use:
:20,30s/^/HelloWorld/
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()
{
auto f1 = std::async(&Test::calculate, this, 0, 10);
auto f2 = std::async(&Test::calculate, this, 11, 20);
auto res1 = f1.get();
auto res2 = f2.get();
}
So long as Excel can open the file, the functionality to change the format of the opened file is built in.
To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).
To do it using VBA, the code would look like this:
Sub Open_HTML_Save_XLSX()
Workbooks.Open Filename:="C:\Temp\Example.html"
ActiveWorkbook.SaveAs Filename:= _
"C:\Temp\Example.xlsx", FileFormat:= _
xlOpenXMLWorkbook
End Sub
The solution is pretty straightforward. Suppose you want to use the "autumn" colormap scheme. The standard version:
cmap = matplotlib.cm.autumn
To reverse the colormap color spectrum, use get_cmap() function and append '_r' to the colormap title like this:
cmap_reversed = matplotlib.cm.get_cmap('autumn_r')
In addition to the above answers, depending on your distro, it may be necessary to execute the bash command from the command line before calling your gsutil command. This is the case for distros that have tcsh or other shell as the default. By typing "bash" the source is changed to the .bashrc file and the file is executed.
# Step 1
bash
# Step 2
gsutil
#Step 3: profit!
