The problem is that your ui
property uses a forward declaration of class Ui::MainWindowClass
, hence the "incomplete type" error.
Including the header file in which this class is declared will fix the problem.
EDIT
Based on your comment, the following code:
namespace Ui
{
class MainWindowClass;
}
does NOT declare a class. It's a forward declaration, meaning that the class will exist at some point, at link time.
Basically, it just tells the compiler that the type will exist, and that it shouldn't warn about it.
But the class has to be defined somewhere.
Note this can only work if you have a pointer to such a type.
You can't have a statically allocated instance of an incomplete type.
So either you actually want an incomplete type, and then you should declare your ui
member as a pointer:
namespace Ui
{
// Forward declaration - Class will have to exist at link time
class MainWindowClass;
}
class MainWindow : public QMainWindow
{
private:
// Member needs to be a pointer, as it's an incomplete type
Ui::MainWindowClass * ui;
};
Or you want a statically allocated instance of Ui::MainWindowClass
, and then it needs to be declared.
You can do it in another header file (usually, there's one header file per class).
But simply changing the code to:
namespace Ui
{
// Real class declaration - May/Should be in a specific header file
class MainWindowClass
{};
}
class MainWindow : public QMainWindow
{
private:
// Member can be statically allocated, as the type is complete
Ui::MainWindowClass ui;
};
will also work.
Note the difference between the two declarations. First uses a forward declaration, while the second one actually declares the class (here with no properties nor methods).
Other way is using of built-in method start timer & event TimerEvent.
Header:
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
private:
Ui::MainWindow *ui;
int timerId;
protected:
void timerEvent(QTimerEvent *event);
};
#endif // MAINWINDOW_H
Source:
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDebug>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
timerId = startTimer(1000);
}
MainWindow::~MainWindow()
{
killTimer(timerId);
delete ui;
}
void MainWindow::timerEvent(QTimerEvent *event)
{
qDebug() << "Update...";
}
First of all, let's try to make your code a little simpler:
// No need to create a circle unless it is clearly necessary to
// demonstrate the problem
// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());
Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:
int main() {
delete new T();
}
This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:
In function 'int main()':
Line 2: error: expected type-specifier before 'T'
Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f
.
In Designer, activate the centralWidget and assign a layout, e.g. horizontal or vertical layout. Then your QFormLayout will automatically resize.
Always make sure, that all widgets have a layout! Otherwise, automatic resizing will break with that widget!
Controls insist on being too large, and won't resize, in QtDesigner
We have just rolled our own due to limited functionality requirements on our grids. We use some JQuery here and there for some niceties like pagination and that is all we really need.
If you need something a little more fully featured you could check out ExtJs grids here.
Also MvcContrib has a grid implementation that you could check out - try here. Or more specifically here.
Since the user can go into the OS menu and select paste using their mouse, there is no safe event that will trigger this for you. The only way I found that always works is to have a setInterval that checks if the input value has changed:
var inp = $('#input'),
val = saved = inp.val(),
tid = setInterval(function() {
val = inp.val();
if ( saved != val ) {
console.log('#input has changed');
saved = val;
},50);
You can also set this up using a jQuery special event.
maybe you are having the same problem i had, my tablet has a SD card on it, in /mnt/sdcard and the sd card external was in /mnt/extcard, you can look it on the android file manager, going to your sd card and see the path to it.
Hope it helps.
I was facing the same issue; and the following worked well for me. Hope this helps someone landing here:
<div class="row">
<div class="col-md-6">
<div class="col-md-12">
Set room heater temperature
</div>
</div>
<div class="col-md-6">
<div class="col-md-12">
Set room heater temperature
</div>
</div>
</div>
This will automatically render some space between the 2 divs.
Yes, it is 128, except for temp tables, whose names can only be up to 116 character long. It is perfectly explained here.
And the verification can be easily made with the following script contained in the blog post before:
DECLARE @i NVARCHAR(800)
SELECT @i = REPLICATE('A', 116)
SELECT @i = 'CREATE TABLE #'+@i+'(i int)'
PRINT @i
EXEC(@i)
For Swift 4.2 / Alamofire 4.7.3
Alamofire.upload(multipartFormData: { multipart in
multipart.append(fileData, withName: "payload", fileName: "someFile.jpg", mimeType: "image/jpeg")
multipart.append("comment".data(using: .utf8)!, withName :"comment")
}, to: "endPointURL", method: .post, headers: nil) { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response { answer in
print("statusCode: \(answer.response?.statusCode)")
}
upload.uploadProgress { progress in
//call progress callback here if you need it
}
case .failure(let encodingError):
print("multipart upload encodingError: \(encodingError)")
}
}
Also you could take a look at CodyFire lib it makes API calls easier using Codable for everything. Example for Multipart call using CodyFire
//Declare your multipart payload model
struct MyPayload: MultipartPayload {
var attachment: Attachment //or you could use just Data instead
var comment: String
}
// Prepare payload for request
let imageAttachment = Attachment(data: UIImage(named: "cat")!.jpeg(.high)!,
fileName: "cat.jpg",
mimeType: .jpg)
let payload = MyPayload(attachment: imageAttachment, comment: "Some text")
//Send request easily
APIRequest("endpoint", payload: payload)
.method(.post)
.desiredStatus(.created) //201 CREATED
.onError { error in
switch error.code {
case .notFound: print("Not found")
default: print("Another error: " + error.description)
}
}.onSuccess { result in
print("here is your decoded result")
}
//Btw normally it should be wrapped into an extension
//so it should look even easier API.some.upload(payload).onError{}.onSuccess{}
You could take a look at all the examples in lib's readme

Open VirtualBox and shut down every VM running.
The shut down should be power off.
And if your virtualbox has been added in the Path in linux (Mine is Ubuntu). You can just use command:
virtualbox restart
You can also implement a contains
method with foldLeft
, it's pretty awesome. I just love foldLeft algorithms.
For example:
object ContainsWithFoldLeft extends App {
val list = (0 to 10).toList
println(contains(list, 10)) //true
println(contains(list, 11)) //false
def contains[A](list: List[A], item: A): Boolean = {
list.foldLeft(false)((r, c) => c.equals(item) || r)
}
}
You can give the surrounding div
a
text-align: right
this will leave white space to the left of the image. (= the image will occupy the whole line).
If you want content to be shown to the left hand side of the image, use
float: right
on the image. However, the surrounding div
will then need overflow: auto
to stretch to the needed height.

In my SQL Server 2008 database, I had a DateTime
column flagged as not nullable, but with a GetDate()
function as its default value. When inserting new object using EF4, I got this error because I wasn't passing a DateTime property on my object explicitly. I expected the SQL function to handle the date for me but it did not. My solution was to send the date value from code instead of relying on the database to generate it.
obj.DateProperty = DateTime.now; // C#
If you want to pass a JavaScript object/hash (ie. an associative array in PHP) then you would do:
$.post('/url/to/page', {'key1': 'value', 'key2': 'value'});
If you wanna pass an actual array (ie. an indexed array in PHP) then you can do:
$.post('/url/to/page', {'someKeyName': ['value','value']});
If you want to pass a JavaScript array then you can do:
$.post('/url/to/page', {'someKeyName': variableName});
The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.
Template:
<div example-directive example-number="99" example-function="exampleCallback()"></div>
Directive:
app.directive('exampleDirective ', function () {
return {
restrict: 'A', // 'A' is the default, so you could remove this line
scope: {
callback : '&exampleFunction',
},
link: function (scope, element, attrs) {
var num = scope.$eval(attrs.exampleNumber);
console.log('number=',num);
scope.callback(); // calls exampleCallback()
}
};
});
If the value of attribute example-number
will be hard-coded, I suggest using $eval
once, and storing the value. Variable num
will have the correct type (a number).
Import the

In case of error
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

Most likely you don't want to deactivate this Header completely, but use SAMEORIGIN
. If you are using the Java Configs (Spring Boot
) and would like to allow the X-Frame-Options: SAMEORIGIN
, then you would need to use the following.
For older Spring Security versions:
http
.headers()
.addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsHeaderWriter.XFrameOptionsMode.SAMEORIGIN))
For newer versions like Spring Security 4.0.2:
http
.headers()
.frameOptions()
.sameOrigin();
In my case [Win64, Python 2.7, cygwin] the issue was with a missing gcc
.
Using apt-cyg install gcc-core

$("input[name='options[]']:checked").each(function ()

I had a similar requirement on my system and this was my solution:
In MATLAB there is a function called perl.m, which allows you to call perl scripts from MATLAB. Depending on which version you are using it will be located somewhere like
C:\Program Files\MATLAB\R2008a\toolbox\matlab\general\perl.m
Create a copy called python.m, a quick search and replace of perl with python, double check the command path it sets up to point to your installation of python. You should now be able to run python scripts from MATLAB.
Example
A simple squared function in python saved as "sqd.py", naturally if I was doing this properly I'd have a few checks in testing input arguments, valid numbers etc.
import sys
def squared(x):
y = x * x
return y
if __name__ == '__main__':
x = float(sys.argv[1])
sys.stdout.write(str(squared(x)))
Then in MATLAB
>> r=python('sqd.py','3.5')
r =
12.25
>> r=python('sqd.py','5')
r =
25.0
>>
Use tow function to solve it ,Very simple and useful:
HTML:
<input class="int-number" type="text" />
<input class="decimal-number" type="text" />
JQuery:
//Integer Number
$(document).on("input", ".int-number", function (e) {
this.value = this.value.replace(/[^0-9]/g, '');
});
//Decimal Number
$(document).on("input", ".decimal-number", function (e) {
this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1');
});
I tried a workaround using the pseudo elements :before
and :after
on the thead th:first-child
and thead th:last-child
In combination with wrapping the table with a <div class="radius borderCCC">
table thead th:first-child:before{
content:" ";
position:absolute;
top:-1px;
left:-1px;
width:15px;
height:15px;
border-left:1px solid #ccc;
border-top:1px solid #ccc;
-webkit-border-radius:5px 0px 0px;
}
table thead th:last-child:after{
content:" ";
position:absolute;
top:-1px;
right:-1px;
width:15px;
height:15px;
border-right:1px solid #ccc;
border-top:1px solid #ccc;
-webkit-border-radius:0px 5px 0px 0px;
}

If you call your classes tests Maven seems to run them automatically, at least they did for me. Rename the classes and Maven will just go through to verification without running them.
Maybe this method would help you for precising double values.
double truncate(double number)
{
int integerPart = (int) number;
double fractionalPart = number - integerPart;
fractionalPart *= 100; //It is for upto two decimal values after point.
//You can increase the zeros to fulfill your needs.
int fractPart = (int) fractionalPart;
fractionalPart = (double) (integerPart) + (double) (fractPart)/100;
return fractionalPart;
}
This method will allow to set the precision level.
double truncate(double number, int precision)
{
double prec = Math.pow(10, precision);
int integerPart = (int) number;
double fractionalPart = number - integerPart;
fractionalPart *= prec;
int fractPart = (int) fractionalPart;
fractionalPart = (double) (integerPart) + (double) (fractPart)/prec;
return fractionalPart;
}
Noticed this is a 2-years old question, but still want to share my workaround for this particular question:
Firstly, run docker container ls -a
to list all the containers you have and pinpoint the want you want to delete.
Secondly, delete the one with command docker container rm <CONTAINER ID>
(If the container is currently running, you should stop it first, run docker container stop <CONTAINER ID>
to gracefully stop the specified container, if it does not stop it for whatever the reason is, alternatively you can run docker container kill <CONTAINER ID> to force shutdown of the specified container
).
Thirdly, remove the container by running docker container rm <CONTAINER ID>
.
Lastly you can run docker image ls -a
to view all the images and delete the one you want to by running docker image rm <hash>
.
google play service is just a library to create application but in order to use application that use google play service library , you need to install google play in your emulator.and for that it need the unique device id. and device id is only on the real device not have on emulator. so for testing it , you need real android device.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).
If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::
.
Something along these lines:
create view view1
as
select table1.col1,table2.col1,table3.col3
from table1
inner join
table2
inner join
table3
on
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;
Notice the varchar
typecasting on the table1.col4.
Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.
Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).
I know this is an old Question, but it popped up when I was looking for a solution to the same issue, so I thought that I would post what worked for me.
<asp:BoundField DataField="Description" HeaderText="Bond Event" ItemStyle-Width="300px" />
I used the ItemStyle-Width
attribute on my BoundField
and it worked very nicely I haven't had any issues yet.
I didn't need to add anything else to the rest of the code to make this work either.
You can create a button in window1 and double click on it. It will create a new click handler, where inside you can write something like this:
var window2 = new Window2();
window2.Show();
I've had so many amazing uses for JMS:
Web chat communication for customer service.
Debug logging on the backend. All app servers broadcasted debug messages at various levels. A JMS client could then be launched to watch for debug messages. Sure I could've used something like syslog, but this gave me all sorts of ways to filter the output based on contextual information (e.q. by app server name, api call, log level, userid, message type, etc...). I also colorized the output.
Debug logging to file. Same as above, only specific pieces were pulled out using filters, and logged to file for general logging.
Alerting. Again, a similar setup to the above logging, watching for specific errors, and alerting people via various means (email, text message, IM, Growl pop-up...)
Dynamically configuring and controlling software clusters. Each app server would broadcast a "configure me" message, then a configuration daemon that would respond with a message containing all kinds of config info. Later, if all the app servers needed their configurations changed at once, it could be done from the config daemon.
And the usual - queued transactions for delayed activity such as billing, order processing, provisioning, email generation...
It's great anywhere you want to guarantee delivery of messages asynchronously.
You can just use git diff
to produce a unified diff suitable for git apply
:
git diff tag1..tag2 > mypatch.patch
You can then apply the resulting patch with:
git apply mypatch.patch
$subscription_key ='';
$host = '';
$request_headers = array(
"X-Mashape-Key:" . $subscription_key,
"X-Mashape-Host:" . $host
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $request_headers);
$season_data = curl_exec($ch);
if (curl_errno($ch)) {
print "Error: " . curl_error($ch);
exit();
}
// Show me the result
curl_close($ch);
$json= json_decode($season_data, true);
Sometimes this will be enough:
int colorInt = getResources().getColor(R.color.ColorVerificaLunes);
ColorStateList csl = ColorStateList.valueOf(colorInt);
The table normally contains multiple rows. Use a loop and use row.Field<string>(0)
to access the value of each row.
foreach(DataRow row in dt.Rows)
{
string file = row.Field<string>("File");
}
You can also access it via index:
foreach(DataRow row in dt.Rows)
{
string file = row.Field<string>(0);
}
If you expect only one row, you can also use the indexer of DataRowCollection
:
string file = dt.Rows[0].Field<string>(0);
Since this fails if the table is empty, use dt.Rows.Count
to check if there is a row:
if(dt.Rows.Count > 0)
file = dt.Rows[0].Field<string>(0);
Python 3.6 gives us f-strings, which are a delight:
var1 = "foo"
var2 = "bar"
var3 = f"{var1}{var2}"
print(var3) # prints foobar
You can do most anything inside the curly braces
print(f"1 + 1 == {1 + 1}") # prints 1 + 1 == 2
At the start, Try to disable your firewall. It helped me. The Eset Smart Security 5 blocked it.
Reference Resolution is described by RFC 3986 Uniform Resource Identifier (URI): Generic Syntax. And that is exactly how it supposed to work. To preserve base URI path you need to add slash at the end of the base URI and remove slash at the beginning of relative URI.
If base URI contains non-empty path, merge procedure discards it's last part (after last /
). Relevant section:
5.2.3. Merge Paths
The pseudocode above refers to a "merge" routine for merging a relative-path reference with the path of the base URI. This is accomplished as follows:
If the base URI has a defined authority component and an empty path, then return a string consisting of "/" concatenated with the reference's path; otherwise
return a string consisting of the reference's path component appended to all but the last segment of the base URI's path (i.e., excluding any characters after the right-most "/" in the base URI path, or excluding the entire base URI path if it does not contain any "/" characters).
If relative URI starts with a slash, it is called a absolute-path relative URI. In this case merge procedure ignore all base URI path. For more information check 5.2.2. Transform References section.
I think you will understand it through these examples below.

if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else
var expires = "";
document.cookie = name + "=" + JSON.stringify(value) + expires + "; path=/";
},
get : function(name){
var nameEQ = name + "=",
ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0)
return JSON.parse(c.substring(nameEQ.length,c.length));
}
return null;
}
}
So, now you can do things like this:
cookie.set('cookie_key', {foo: 'bar'}, 30);
cookie.get('cookie_key'); // {foo: 'bar'}
cookie.set('cookie_key', 'baz', 30);
cookie.get('cookie_key'); // 'baz'
You can make use of the SlimScroll plugin to make a div scrollable even if it is set to overflow: hidden;
(i.e. scrollbar hidden).
You can also control touch scroll as well as the scroll speed using this plugin.
Hope this helps :)
On the Unity Editor open your project and:
If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:
cd to/your/unity/project/folder
git init
git add *
git commit -m "First commit"
git remote add origin [email protected]:username/project.git
git push -u origin master
You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).
Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.
And here's my own .gitignore recipe for my Unity projects:

The simple solution would be to use a ItemListener
. When the state changes, you would simply check the currently selected item and set the text accordingly
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestComboBox06 {
public static void main(String[] args) {
new TestComboBox06();
}
public TestComboBox06() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException ex) {
} catch (InstantiationException ex) {
} catch (IllegalAccessException ex) {
} catch (UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JComboBox cb;
private JTextField field;
public TestPane() {
cb = new JComboBox(new String[]{"Item 1", "Item 2"});
field = new JTextField(12);
add(cb);
add(field);
cb.setSelectedItem(null);
cb.addItemListener(new ItemListener() {
@Override
public void itemStateChanged(ItemEvent e) {
Object item = cb.getSelectedItem();
if ("Item 1".equals(item)) {
field.setText("20");
} else if ("Item 2".equals(item)) {
field.setText("30");
}
}
});
}
}
}
A better solution would be to create a custom object that represents the value to be displayed and the value associated with it...

Have you considered reading a book on PHP security? Highly recommended.
I have had much success with the following method for non SSL certified sites.
Dis-allow multiple sessions under the same account, making sure you aren't checking this solely by IP address. Rather check by token generated upon login which is stored with the users session in the database, as well as IP address, HTTP_USER_AGENT and so forth
Using Relation based hyperlinks Generates a link ( eg. http://example.com/secure.php?token=2349df98sdf98a9asdf8fas98df8 ) The link is appended with a x-BYTE ( preferred size ) random salted MD5 string, upon page redirection the randomly generated token corresponds to a requested page.
Short Life-span session authentication cookie. as posted above, a cookie containing a secure string, which is one of the direct references to the sessions validity is a good idea. Make it expire every x Minutes, reissuing that token, and re-syncing the session with the new Data. If any mis-matches in the data, either log the user out, or having them re-authenticate their session.
I am in no means an expert on the subject, I'v had a bit of experience in this particular topic, hope some of this helps anyone out there.
If you're still wondering how to solve it.
I use
$protected $dates = ['created_at','updated_at','aired'];
In my model and in my where i do
where('aired','>=',time())
So just use the unix to compaire in where.
In views on the otherhand you have to use the date object.
Hope it helps someone!
When in doubt, read the documentation:
filename = "C:\Temp\vblist.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
Do Until f.AtEndOfStream
WScript.Echo f.ReadLine
Loop
f.Close
Open the workbook as hidden and then set it as "saved" so that users are not prompted when they close out.
Dim w As Workbooks
Private Sub Workbook_Open()
Application.ScreenUpdating = False
Set w = Workbooks
w.Open Filename:="\\server\PriceList.xlsx", UpdateLinks:=False, ReadOnly:=True 'this is the data file were going to be opening
ActiveWindow.Visible = False
ThisWorkbook.Activate
Application.ScreenUpdating = True
End Sub
Private Sub Workbook_BeforeClose(Cancel As Boolean)
w.Item(2).Saved = True 'this will suppress the safe prompt for the data file only
End Sub
This is somewhat derivative of the answer posted by Ashok.
By doing it this way though you will not get prompted to save changes back to the Excel file your reading from. This is great if the Excel file your reading from is intended as a data source for validation. For example if the workbook contains product names and price data it can be hidden and you can show an Excel file that represents an invoice with drop downs for product that validates from that price list.
You can then store the price list on a shared location on a network somewhere and make it read-only.
Did they add a runtime List<> and/or Map<> type class to typepad 1.0
No, providing a runtime is not the focus of the TypeScript team.
is there a solid library out there someone wrote that provides this functionality?
I wrote (really just ported over buckets to typescript): https://github.com/basarat/typescript-collections
JavaScript / TypeScript now support this natively and you can enable them with lib.d.ts
: https://basarat.gitbooks.io/typescript/docs/types/lib.d.ts.html along with a polyfill if you want
If your data has a regular structure you can read a file in line by line and populate your favorite container. For example:
Let's say your data has 3 variables: x, y, i.
A file contains n of these data, each variable on its own line (3 lines per record). Here are two records:
384
198
0
255
444
2
Here's how you read your file data into a list. (Reading from text, so cast accordingly.)
data = []
try:
with open(dataFilename, "r") as file:
# read data until end of file
x = file.readline()
while x != "":
x = int(x.strip()) # remove \n, cast as int
y = file.readline()
y = int(y.strip())
i = file.readline()
i = int(i.strip())
data.append([x,y,i])
x = file.readline()
except FileNotFoundError as e:
print("File not found:", e)
return(data)
Only the answers that push the value into the registry affect a permanent change (so the majority of answers on this thread, including the accepted answer, do not permanently affect the Path
).
The following function works for both Path
/ PSModulePath
and for User
/ System
types. It will also add the new path to the current session by default.
function AddTo-Path {
param (
[string]$PathToAdd,
[Parameter(Mandatory=$true)][ValidateSet('System','User')][string]$UserType,
[Parameter(Mandatory=$true)][ValidateSet('Path','PSModulePath')][string]$PathType
)
# AddTo-Path "C:\XXX" "PSModulePath" 'System'
if ($UserType -eq "System" ) { $RegPropertyLocation = 'HKLM:\System\CurrentControlSet\Control\Session Manager\Environment' }
if ($UserType -eq "User" ) { $RegPropertyLocation = 'HKCU:\Environment' } # also note: Registry::HKEY_LOCAL_MACHINE\ format
$PathOld = (Get-ItemProperty -Path $RegPropertyLocation -Name $PathType).$PathType
"`n$UserType $PathType Before:`n$PathOld`n"
$PathArray = $PathOld -Split ";" -replace "\\+$", ""
if ($PathArray -notcontains $PathToAdd) {
"$UserType $PathType Now:" # ; sleep -Milliseconds 100 # Might need pause to prevent text being after Path output(!)
$PathNew = "$PathOld;$PathToAdd"
Set-ItemProperty -Path $RegPropertyLocation -Name $PathType -Value $PathNew
Get-ItemProperty -Path $RegPropertyLocation -Name $PathType | select -ExpandProperty $PathType
if ($PathType -eq "Path") { $env:Path += ";$PathToAdd" } # Add to Path also for this current session
if ($PathType -eq "PSModulePath") { $env:PSModulePath += ";$PathToAdd" } # Add to PSModulePath also for this current session
"`n$PathToAdd has been added to the $UserType $PathType"
}
else {
"'$PathToAdd' is already in the $UserType $PathType. Nothing to do."
}
}
# Add "C:\XXX" to User Path (but only if not already present)
AddTo-Path "C:\XXX" "User" "Path"
# Just show the current status by putting an empty path
AddTo-Path "" "User" "Path"
Have tried most of the examples here if not all but none seem to be working in my case. After struggling for quite some time I have tried using as.character() on the factor column to change it to a col with strings which seems to working just fine.
Not sure for performance issues.
In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.:
$msg = Read-Host -Prompt "Enter message"
$encmsg = [System.Web.HttpUtility]::UrlEncode($msg)
Invoke-WebRequest -Uri "http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255"
If you don't want to add a new column, and you can guarantee that your current int column is unique, you could select all of the data out into a temporary table, drop the table and recreate with the IDENTITY column specified. Then using SET IDENTITY INSERT ON
you can insert all of your data in the temporary table into the new table.
Iterate through the array, and splice
out the ones you don't want. For easier use, iterate backwards so you don't have to take into account the live nature of the array:
for (var i = myArray.length - 1; i >= 0; --i) {
if (myArray[i].field == "money") {
myArray.splice(i,1);
}
}
Right click on the project in Eclipse -> Android tools -> Export without signed key. Connect your device. Mount it by sdk/tools.
Rather than adding libraries which increases your apk size, I will suggest you to convert Svg to drawable using http://inloop.github.io/svg2android/ .
and add vectorDrawables.useSupportLibrary = true
in gradle,
You could try this:
Simply place the code in a style tag in the head of the html file
<style>_x000D_
.jumbotron {_x000D_
background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
}_x000D_
</style>
_x000D_
or put it in a separate css file as shown below
.jumbotron {_x000D_
background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
}
_x000D_
use center center to center the image horizontally and vertically. use cover to make the image fill out the jumbotron space and finally no-repeat so that the image is not repeated.
I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).
MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.
This code works even if the substring contains more than 1 character.
DECLARE @FilePath VARCHAR(100) = 'My_sub_Super_sub_Long_sub_String_sub_With_sub_Long_sub_Words'
DECLARE @FindSubstring VARCHAR(5) = '_sub_'
-- Shows text before last substing
SELECT LEFT(@FilePath, LEN(@FilePath) - CHARINDEX(REVERSE(@FindSubstring), REVERSE(@FilePath)) - LEN(@FindSubstring) + 1) AS Before
-- Shows text after last substing
SELECT RIGHT(@FilePath, CHARINDEX(REVERSE(@FindSubstring), REVERSE(@FilePath)) -1) AS After
-- Shows the position of the last substing
SELECT LEN(@FilePath) - CHARINDEX(REVERSE(@FindSubstring), REVERSE(@FilePath)) AS LastOccuredAt
I had met a similar problem, after i add a scope property of servlet dependency in pom.xml
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
Then it was ok . maybe that will help you.
First of all, do you really need to store the values? You may just use the view that does the job:
SELECT t."date",
x."number" AS "number"
FROM @Table t
JOIN @Table x
ON x."date" = (SELECT TOP 1 z."date"
FROM @Table z
WHERE z."date" <= t."date"
AND z."number" IS NOT NULL
ORDER BY z."date" DESC)
If you really do have the ID ("date")
column and it is a primary key (clustered), then this query should be pretty fast. But check the query plan: it might be better to have a cover index including the Val
column as well.
Also if you do not like procedures when you can avoid them, you can also use similar query for UPDATE
:
UPDATE t
SET t."number" = x."number"
FROM @Table t
JOIN @Table x
ON x."date" = (SELECT TOP 1 z."date"
FROM @Table z
WHERE z."date" < t."date" --//@note: < and not <= here, as = not required
AND z."number" IS NOT NULL
ORDER BY z."date" DESC)
WHERE t."number" IS NULL
NOTE: the code must works on "SQL Server".
Ok so there are many answers here and I dont think they answer your question which I think is similar to mine.
You need to do an operation like contacting a database or third part api that will take time and is asyncronus. You do not want to load the entire document into memory due to being to large or some other reason so you need to read line by line to process.
I have read into the fs documents and it can pause on reading but using .on('data') call will make it continous which most of these answer use and cause the problem.
UPDATE: I know more info about Streams than I ever wanted
The best way to do this is to create a writable stream. This will pipe the csv data into your writable stream which you can manage asyncronus calls. The pipe will manage the buffer all the way back to the reader so you will not wind up with heavy memory usage
Simple Version
const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')
const mySimpleWritable = new stream.Writable({
objectMode: true, // Because input is object from csv-parser
write(chunk, encoding, done) { // Required
// chunk is object with data from a line in the csv
console.log('chunk', chunk)
done();
},
final(done) { // Optional
// last place to clean up when done
done();
}
});
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(mySimpleWritable)
Class Version
const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')
// Create writable class
class MyWritable extends stream.Writable {
// Used to set object mode because we get an object piped in from csv-parser
constructor(another_variable, options) {
// Calls the stream.Writable() constructor.
super({ ...options, objectMode: true });
// additional information if you want
this.another_variable = another_variable
}
// The write method
// Called over and over, for each line in the csv
async _write(chunk, encoding, done) {
// The chunk will be a line of your csv as an object
console.log('Chunk Data', this.another_variable, chunk)
// demonstrate await call
// This will pause the process until it is finished
await new Promise(resolve => setTimeout(resolve, 2000));
// Very important to add. Keeps the pipe buffers correct. Will load the next line of data
done();
};
// Gets called when all lines have been read
async _final(done) {
// Can do more calls here with left over information in the class
console.log('clean up')
// lets pipe know its done and the .on('final') will be called
done()
}
}
// Instantiate the new writable class
myWritable = new MyWritable(somevariable)
// Pipe the read stream to csv-parser, then to your write class
// stripBom is due to Excel saving csv files with UTF8 - BOM format
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(myWritable)
// optional
.on('finish', () => {
// will be called after the wriables internal _final
console.log('Called very last')
})
OLD METHOD:
PROBLEM WITH readable
const csv = require('csv-parser');
const fs = require('fs');
const processFileByLine = async(fileNameFull) => {
let reading = false
const rr = fs.createReadStream(fileNameFull)
.pipe(csv())
// Magic happens here
rr.on('readable', async function(){
// Called once when data starts flowing
console.log('starting readable')
// Found this might be called a second time for some reason
// This will stop that event from happening
if (reading) {
console.log('ignoring reading')
return
}
reading = true
while (null !== (data = rr.read())) {
// data variable will be an object with information from the line it read
// PROCESS DATA HERE
console.log('new line of data', data)
}
// All lines have been read and file is done.
// End event will be called about now so that code will run before below code
console.log('Finished readable')
})
rr.on("end", function () {
// File has finished being read
console.log('closing file')
});
rr.on("error", err => {
// Some basic error handling for fs error events
console.log('error', err);
});
}
You will notice a reading
flag. I have noticed that for some reason right near the end of the file the .on('readable') gets called a second time on small and large files. I am unsure why but this blocks that from a second process reading the same line items.
This helped me to call API that was using cookie authentication. I have passed authorization in header like this:
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
complete code:
// utility method to read the cookie value:
public static string ReadCookie(string cookieName)
{
var cookies = HttpContext.Current.Request.Cookies;
var cookie = cookies.Get(cookieName);
if (cookie != null)
return cookie.Value;
return null;
}
// using statements where you are creating your webclient
using System.Web.Script.Serialization;
using System.Net;
using System.IO;
// WebClient:
var requestUrl = "<API_url>";
var postRequest = new ClassRoom { name = "kushal seth" };
using (var webClient = new WebClient()) {
JavaScriptSerializer serializer = new JavaScriptSerializer();
byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = requestData.Length;
request.ContentType = "application/json";
request.Expect = "application/json";
request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
request.GetRequestStream().Write(requestData, 0, requestData.Length);
using (var response = (HttpWebResponse)request.GetResponse()) {
var reader = new StreamReader(response.GetResponseStream());
var objText = reader.ReadToEnd(); // objText will have the value
}
}
sudo apt-get install python3-pip
sudo pip3 install MODULE_NAME
Source: Shashank Bharadwaj's comment
The short answer applies only on newer systems. On some versions of Ubuntu the command is pip-3.2
:
sudo pip-3.2 install MODULE_NAME
If it doesn't work, this method should work for any Linux distro and supported version:
sudo apt-get install curl
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
sudo pip3 install MODULE_NAME
If you don't have curl
, use wget
. If you don't have sudo
, switch to root
. If pip3
symlink does not exists, check for something like pip-3.X
Much python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Sources:
python installing packages with pip
Pip latest install
Check also Tobu's answer if you want an even more upgraded version of Python.
I want to add that using a virtual environment is usually the preferred way to develop a python application, so @felixyan answer is probably the best in an ideal world. But if you really want to install that package globally, or if need to test / use it frequently without activating a virtual environment, I suppose installing it as a global package is the way to go.
i am using like this.. its easy to understand first argument is mapStateToProps and second argument is mapDispatchToProps in the end connect with function/class.
const mapStateToProps = (state) => {
return {
todos: getVisibleTodos(state.todos, state.visibilityFilter)
}
}
const mapDispatchToProps = (dispatch) => {
return {
onTodoClick: (id) => {
dispatch(toggleTodo(id))
}
}
}
export default connect(mapStateToProps,mapDispatchToProps)(TodoList);
An easier alternative for those who would prefer not to write all that configuration boilerplate manually...
1) Install Nerdle.AutoConfig from NuGet
2) Define your ServiceConfig type (either a concrete class or just an interface, either will do)
public interface IServiceConfiguration
{
int Port { get; }
ReportType ReportType { get; }
}
3) You'll need a type to hold the collection, e.g.
public interface IServiceCollectionConfiguration
{
IEnumerable<IServiceConfiguration> Services { get; }
}
4) Add the config section like so (note camelCase naming)
<configSections>
<section name="serviceCollection" type="Nerdle.AutoConfig.Section, Nerdle.AutoConfig"/>
</configSections>
<serviceCollection>
<services>
<service port="6996" reportType="File" />
<service port="7001" reportType="Other" />
</services>
</serviceCollection>
5) Map with AutoConfig
var services = AutoConfig.Map<IServiceCollectionConfiguration>();
Just came accross this use case. I implemented gens's answer, adding a recursive approach for handling values that are also dicts:
def mutate_dict_in_place(f, d):
for k, v in d.iteritems():
if isinstance(v, dict):
mutate_dict_in_place(f, v)
else:
d[k] = f(v)
# Exemple handy usage
def utf8_everywhere(d):
mutate_dict_in_place((
lambda value:
value.decode('utf-8')
if isinstance(value, bytes)
else value
),
d
)
my_dict = {'a': b'byte1', 'b': {'c': b'byte2', 'd': b'byte3'}}
utf8_everywhere(my_dict)
print(my_dict)
This can be useful when dealing with json or yaml files that encode strings as bytes in Python 2
I get such warning in following case:
1) file1 which contains <script type="text/javascript" src="/javascript/jquery-1.10.2.js"></script>
. Page has input fields. I enter some value in input field and click button. Jquery sends input to external php file.
2) external php file also contains jquery and in the external php file i also included <script type="text/javascript" src="/javascript/jquery-1.10.2.js"></script>
. Because if this i got the warning.
Removed <script type="text/javascript" src="/javascript/jquery-1.10.2.js"></script>
from external php file and works without the warning.
As i understand on loading the first file (file1), i load jquery-1.10.2.js
and as the page does not reloads (it sends data to external php file using jquery $.post
), then jquery-1.10.2.js
continue to exist. So not necessary again to load it.
use this code <script> $('#someid').attr('disabled,'true'); </script>
You can start with a custom number and increment from there, for example you want to add a cheque number for each payment you can do:

Got a similar error on IIS Express with Visual Studio 2017.
HTTP Error 413.0 - Request Entity Too Large
The page was not displayed because the request entity is too large.
Most likely causes:
The Web server is refusing to service the request because the request entity is too large.
The Web server cannot service the request because it is trying to negotiate a client certificate but the request entity is too large.
The request URL or the physical mapping to the URL (i.e., the physical file system path to the URL's content) is too long.
Things you can try:
Verify that the request is valid.
If using client certificates, try:
Increasing system.webServer/serverRuntime@uploadReadAheadSize
Configure your SSL endpoint to negotiate client certificates as part of the initial SSL handshake. (netsh http add sslcert ... clientcertnegotiation=enable) .vs\config\applicationhost.config
Solve this by editing \.vs\config\applicationhost.config
. Switch serverRuntime
from Deny
to Allow
like this:
<section name="serverRuntime" overrideModeDefault="Allow" />
If this value is not edited, you will get an error like this when setting uploadReadAheadSize
:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
Then edit Web.config
with the following values:
<system.webServer>
<serverRuntime uploadReadAheadSize="10485760" />
...
You can try of the following type :
#!/bin/bash
declare -a arr
i=0
j=0
for dir in $(find /home/rmajeti/programs -type d)
do
arr[i]=$dir
i=$((i+1))
done
while [ $j -lt $i ]
do
echo ${arr[$j]}
j=$((j+1))
done
The issue was in fact that one of the properties was a relation to another table. I changed my LINQ query so that it could get the same data from a different method without needing to load the entire table.
Thank you all for your help!
This question has already accepted answer but now a days one more NoSQL DB is in trend for many of its great features. It is Couchbase
; which runs as CouchbaseLite
on mobile platform and Couchbase Server
on your server side.
Here is some of main features of Couchbase Lite.
Couchbase Lite is a lightweight, document-oriented (NoSQL), syncable database engine suitable for embedding into mobile apps.
Lightweight means:
Embedded—the database engine is a library linked into the app, not a separate server process. Small code size—important for mobile apps, which are often downloaded over cell networks. Quick startup time—important because mobile devices have relatively slow CPUs. Low memory usage—typical mobile data sets are relatively small, but some documents might have large multimedia attachments. Good performance—exact figures depend on your data and application, of course.
Document-oriented means:
Stores records in flexible JSON format instead of requiring predefined schemas or normalization. Documents can have arbitrary-sized binary attachments, such as multimedia content. Application data format can evolve over time without any need for explicit migrations. MapReduce indexing provides fast lookups without needing to use special query languages.
Syncable means:
Any two copies of a database can be brought into sync via an efficient, reliable, proven replication algorithm. Sync can be on-demand or continuous (with a latency of a few seconds). Devices can sync with a subset of a large database on a remote server. The sync engine supports intermittent and unreliable network connections. Conflicts can be detected and resolved, with app logic in full control of merging. Revision trees allow for complex replication topologies, including server-to-server (for multiple data centers) and peer-to-peer, without data loss or false conflicts. Couchbase Lite provides native APIs for seamless iOS (Objective-C) and Android (Java) development. In addition, it includes the Couchbase Lite Plug-in for PhoneGap, which enables you to build iOS and Android apps that you develop by using familiar web-application programming techniques and the PhoneGap mobile development framework.

This is going to the next big thing.
If one row of the data contains the names you want to change all columns to you can do
names(data) <- data[row,]
Given data
is your dataframe and row
is the row number containing the new values.
Then you can remove the row containing the names with
data <- data[-row,]
The string ctor is suitable for this conversion:
System.out.println("string " + new String(new byte[] {0x63}));
Very edge case, but I had to use a program that worked correctly only when I specified
StartInfo = {..., RedirectStandardOutput = true}
Not specifying it would result in an error. There was not even the need to read the output afterward.
You can use gmtime
from time import gmtime
detailed_time = gmtime()
#returns a struct_time object for current time
year = detailed_time.tm_year
month = detailed_time.tm_mon
day = detailed_time.tm_mday
hour = detailed_time.tm_hour
minute = detailed_time.tm_min
Note: A time stamp can be passed to gmtime, default is current time as returned by time()
eg.
gmtime(1521174681)
See struct_time
How to fish and while using strict code. There are two prerequisite functions needed at the bottom of this post.
xml_add('before', id_('element_after'), '<span xmlns="http://www.w3.org/1999/xhtml">Some text.</span>');
xml_add('after', id_('element_before'), '<input type="text" xmlns="http://www.w3.org/1999/xhtml" />');
xml_add('inside', id_('element_parent'), '<input type="text" xmlns="http://www.w3.org/1999/xhtml" />');
Add multiple elements (namespace only needs to be on the parent element):
xml_add('inside', id_('element_parent'), '<div xmlns="http://www.w3.org/1999/xhtml"><input type="text" /><input type="button" /></div>');
Dynamic reusable code:
function id_(id) {return (document.getElementById(id)) ? document.getElementById(id) : false;}
function xml_add(pos, e, xml)
{
e = (typeof e == 'string' && id_(e)) ? id_(e) : e;
if (e.nodeName)
{
if (pos=='after') {e.parentNode.insertBefore(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e.nextSibling);}
else if (pos=='before') {e.parentNode.insertBefore(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e);}
else if (pos=='inside') {e.appendChild(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true));}
else if (pos=='replace') {e.parentNode.replaceChild(document.importNode(new DOMParser().parseFromString(xml,'application/xml').childNodes[0],true),e);}
//Add fragment and have it returned.
}
}
The full JSP tag should be something like this, mind the pageEncoding too:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
Some old browsers mess up with the encoding too. you can use the HTML tag
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
Also the file should be recorded in UTF-8 format, if you are using Eclipse left-click on the file->Properties->Check out ->Text file encoding.
Much easier way:
$('#test').css('textTransform', 'capitalize');
I have to give @Dementic some credit for leading me down the right path. Far simpler than whatever you guys are proposing.
git log --full-history -- [file path]
shows the changes of a file and works even if the file was deleted.
Example:
git log --full-history -- myfile
If you want to see only the last commit, which deleted the file, use -1
in addition to the command above. Example:
git log --full-history -1 -- [file path]
See also my article: Which commit deleted a file.
public String replace(String input, Map<String, String> pairs) {
// Reverse lexic-order of keys is good enough for most cases,
// as it puts longer words before their prefixes ("tool" before "too").
// However, there are corner cases, which this algorithm doesn't handle
// no matter what order of keys you choose, eg. it fails to match "edit"
// before "bed" in "..bedit.." because "bed" appears first in the input,
// but "edit" may be the desired longer match. Depends which you prefer.
final Map<String, String> sorted =
new TreeMap<String, String>(Collections.reverseOrder());
sorted.putAll(pairs);
final String[] keys = sorted.keySet().toArray(new String[sorted.size()]);
final String[] vals = sorted.values().toArray(new String[sorted.size()]);
final int lo = 0, hi = input.length();
final StringBuilder result = new StringBuilder();
int s = lo;
for (int i = s; i < hi; i++) {
for (int p = 0; p < keys.length; p++) {
if (input.regionMatches(i, keys[p], 0, keys[p].length())) {
/* TODO: check for "edit", if this is "bed" in "..bedit.." case,
* i.e. look ahead for all prioritized/longer keys starting within
* the current match region; iff found, then ignore match ("bed")
* and continue search (find "edit" later), else handle match. */
// if (better-match-overlaps-right-ahead)
// continue;
result.append(input, s, i).append(vals[p]);
i += keys[p].length();
s = i--;
}
}
}
if (s == lo) // no matches? no changes!
return input;
return result.append(input, s, hi).toString();
}
From a user experience stand-point, you don't want a major action to be done passively.
Something major like a window close should be the result of an action by the user.
You cannot simply add a link using CSS. CSS is used for styling.
You can style your using CSS.
If you want to give a link dynamically to then I will advice you to use jQuery or Javascript.
You can accomplish that very easily using jQuery.
I have done a sample for you. You can refer that.
$('#link').attr('href','http://www.google.com');
This single line will do the trick.
Write the table name in the query editor select the name and press Alt+F1 and it will bring all the information of the table.
I found when I accessed here https://console.cloud.google.com/home/dashboard
Then I got redirected to my active project, which was something like https://console.cloud.google.com/home/dashboard?project={THE_ID_OF_YOUR_PROJECT}
Then right bellow the project info, there was this Manage Options (note: I'm using Portuguese language here "Gerenciar as configurações do projeto" means "Manage project settings")
Then, finally, the delete option ("Excluir Projeto" means Delete Project)
Yep, it was hard
Multiple pdf merged method using org.apache.pdfbox:
public void mergePDFFiles(List<File> files,
String mergedFileName) {
try {
PDFMergerUtility pdfmerger = new PDFMergerUtility();
for (File file : files) {
PDDocument document = PDDocument.load(file);
pdfmerger.setDestinationFileName(mergedFileName);
pdfmerger.addSource(file);
pdfmerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());
document.close();
}
} catch (IOException e) {
logger.error("Error to merge files. Error: " + e.getMessage());
}
}
From main program, call mergePDFFiles method using list of files and target file name.
String mergedFileName = "Merged.pdf";
mergePDFFiles(files, mergedFileName);
After calling mergePDFFiles, load merged file
File mergedFile = new File(mergedFileName);
you need a file named __init__.py
(two underscores on each side) in every folder in the hierarchy, so one in src/
and one in model/
. This is what python looks for to know that it should access a particular folder. The files are meant to contain initialization instructions but even if you create them empty this will solve it.
Why yet another howto? There are really good ones on the net, like the git guide which is perfect to begin. It has good links including the git book to which one can contribute (hosted on git hub) and which is perfect for this collective task.
On stackoverflow, I would really prefer to see your favorite tricks !
Mine, which I discovered only lately, is git stash
, explained here, which enables you to save your current job and go to another branch
EDIT: as the previous post, if you really prefer stackoverlow format with posts as a wiki I will delete this answer
You've got to override your Canvas's paint(Graphics g)
method and perform your drawing there. See the paint() documentation.
As it states, the default operation is to clear the canvas, so your call to the canvas' graphics object doesn't perform as you would expect.
Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type
C:\folder\app.exe/xC:\folder\file.txt
then my application launches, and creates a file in the specified directory with the specified name.
I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put
$s = New-PSSession -computername NAME -credential LOGIN
Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s
(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.
*I can also have my application push the file back to my own local computer by changing the script-block to
C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"
You need the quotes if your file-path has a space in it.
EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:
cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"
this solved all of the problems that I have been having recently.
EDIT EDIT: Had more problems, and found a much better way to do it.
start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"
and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)
There's a general point to be made about such optimizations.
The optimization you get is proportional to the amount of time the program counter is actually in that code.
If you sample the program counter, you will find out where it spends its time, and that is usually in a tiny part of the code, and often in library routines you have no control over.
Only if you find it spending much time in the heap-allocation of your objects will it be noticeably faster to stack-allocate them.

It is a little tricky. First you can use keytool to put the private key into PKCS12 format, which is more portable/compatible than Java's various keystore formats. Here is an example taking a private key with alias 'mykey' in a Java keystore and copying it into a PKCS12 file named myp12file.p12
.
[note that on most screens this command extends beyond the right side of the box: you need to scroll right to see it all]
keytool -v -importkeystore -srckeystore .keystore -srcalias mykey -destkeystore myp12file.p12 -deststoretype PKCS12
Enter destination keystore password:
Re-enter new password:
Enter source keystore password:
[Storing myp12file.p12]
Now the file myp12file.p12
contains the private key in PKCS12 format which may be used directly by many software packages or further processed using the openssl pkcs12
command. For example,
openssl pkcs12 -in myp12file.p12 -nocerts -nodes
Enter Import Password:
MAC verified OK

Here's another way to process command line args, using R CMD BATCH
. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.
Here's an R file, which I name test.R:
defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass
## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
eval(parse(text=arg))
## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])
print(a)
print(b)
At the command line, if I type
R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R
then within R we'll have a
= 2
and b
= c(2,5,6)
. But I could, say, omit b
, and add in another argument c
:
R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R
Then in R we'll have a
= 2
, b
= c(1,1,1)
(the default), and c
= "hello"
.
Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:
## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
for (arg in commandArgs(TRUE))
eval(parse(text=arg), envir=envir)
for (nm in names(defaults))
assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}
## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))
I have that problem and my solution is going source folder and run command line: mvn clean install -DskipTests eclipse:eclipse then return eclipse workspace and refresh project. Hope that help!
It is because you haven't qualified Cells(1, 1)
with a worksheet object, and the same holds true for Cells(10, 2)
. For the code to work, it should look something like this:
Dim ws As Worksheet
Set ws = Sheets("SheetName")
Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents
Alternately:
With Sheets("SheetName")
Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With
EDIT: The Range object will inherit the worksheet from the Cells objects when the code is run from a standard module or userform. If you are running the code from a worksheet code module, you will need to qualify Range
also, like so:
ws.Range(ws.Cells(1, 1), ws.Cells(10, 2)).ClearContents
or
With Sheets("SheetName")
.Range(.Cells(1, 1), .Cells(10, 2)).ClearContents
End With
Your 0xED 0x6E 0x2C 0x20 bytes correspond to "ín, " in ISO-8859-1, so it looks like your content is in ISO-8859-1, not UTF-8. Tell your data provider about it and ask them to fix it, because if it doesn't work for you it probably doesn't work for other people either.
Now there are a few ways to work it around, which you should only use if you cannot load the XML normally. One of them would be to use utf8_encode()
. The downside is that if that XML contains both valid UTF-8 and some ISO-8859-1 then the result will contain mojibake. Or you can try to convert the string from UTF-8 to UTF-8 using iconv()
or mbstring, and hope they'll fix it for you. (they won't, but you can at least ignore the invalid characters so you can load your XML)
Or you can take the long, long road and validate/fix the sequences by yourself. That will take you a while depending on how familiar you are with UTF-8. Perhaps there are libraries out there that would do that, although I don't know any.
Either way, notify your data provider that they're sending invalid data so that they can fix it.
Here's a partial fix. It will definitely not fix everything, but will fix some of it. Hopefully enough for you to get by until your provider fix their stuff.
function fix_latin1_mangled_with_utf8_maybe_hopefully_most_of_the_time($str)
{
return preg_replace_callback('#[\\xA1-\\xFF](?![\\x80-\\xBF]{2,})#', 'utf8_encode_callback', $str);
}
function utf8_encode_callback($m)
{
return utf8_encode($m[0]);
}
Hibernate's PostgreSQL dialect isn't very bright. It doesn't know about your per-SERIAL sequences, and is assuming there's a global database-wide sequence called "hibernate_sequence" that it can use.
(UPDATE: It appears that newer Hibernate versions may use the default per-table sequences when GenerationType.IDENTITY
is specified. Test your version and use this instead of the below if it works for you.)
You need to change your mappings to explicitly specify each sequence. It's annoying, repetitive, and pointless.
@Entity
@Table(name = "JUDGEMENTS")
public class Judgement implements Serializable, Cloneable {
private static final long serialVersionUID = -7049957706738879274L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator="judgements_id_seq")
@SequenceGenerator(name="judgements_id_seq", sequenceName="judgements_id_seq", allocationSize=1)
@Column(name = "JUD_ID")
private Long _judId;
...
The allocationSize=1
is quite important. If you omit it, Hibernate will blindly assume that the sequence is defined with INCREMENT 50
so when it gets a value from a sequence it can use that value and the 49 values below it as unique generated keys. If your database sequences increment by 1 - the default - then this will result in unique violations as Hibernate tries to re-use existing keys.
Note that getting one key at a time will result in an additional round trip per insert. As far as I can tell Hibernate isn't capable of using INSERT ... RETURNING
to efficiently return generated keys, nor can it apparently use the JDBC generated keys interface. If you tell it to use a sequence, it'll call nextval
to get the value then insert
that explicitly, resulting in two round trips. To reduce the cost of that, you can set a greater increment on key sequences with lots of inserts , remembering to set it on the mapping and the underlying database sequence. That'll cause Hibernate to call nextval
less frequently and cache blocks of keys to hand out as it goes.
I'm sure you can see from the above that I don't agree with the Hibernate design choices made here, at least from the perspective of using it with PostgreSQL. They should be using getGeneratedKeys
or using INSERT ... RETURNING
with DEFAULT
for the key, letting the database take care of this without Hibernate having to trouble its self over the names of the sequences or explicit access to them.
BTW, if you're using Hibernate with Pg you'll possibly also want an oplock trigger for Pg to allow Hibernate's optimistic locking to interact safely with normal database locking. Without it or something like it your Hibernate updates will tend to clobber changes made via other regular SQL clients. Ask me how I know.
The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.
To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.
Could I write "table" or any other html tag instead of "/" ?
Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.
Here a few links:

When the script is not in the Path its required to do so. For more info read http://www.tldp.org/LDP/Bash-Beginners-Guide/html/sect_02_01.html
First check the URL it might be wrong, if it is correct then check the request body which you are sending, the possible cause is request that you are sending is missing right syntax.
To elaborate , check for special characters in the request string. If it is (special char) being used this is the root cause of this error.
try copying the request and analyze each and every tags data.

On MacOS, you can follow below instructions to install sshpass:
This is absolutely possible. Although you shouldn't do it unless you know what you are dealing with. Took me about 2 days to figure it out. Here is a stored procedure where i enter: ---database name (schema name is "_" for readability) ---table name ---column ---column data type (column added is always null, otherwise you won't be able to insert) ---the position of the new column.
Since I'm working with tables from SAM toolkit (and some of them have > 80 columns) , the typical variable won't be able to contain the query. That forces the need of external file. Now be careful where you store that file and who has access on NTFS and network level.

The spaceship (<=>
) method can be used to compare two strings in relation to their alphabetical ranking. The <=> method returns 0 if the strings are identical, -1 if the left hand string is less than the right hand string, and 1 if it is greater:
"Apples" <=> "Apples"
=> 0
"Apples" <=> "Pears"
=> -1
"Pears" <=> "Apples"
=> 1
A case insensitive comparison may be performed using the casecmp method which returns the same values as the <=> method described above:
"Apples".casecmp "apples"
=> 0

Shell Script Loader is my solution for this.
It provides a function named include() that can be called many times in many scripts to refer a single script but will only load the script once. The function can accept complete paths or partial paths (script is searched in a search path). A similar function named load() is also provided that will load the scripts unconditionally.
It works for bash, ksh, pd ksh and zsh with optimized scripts for each one of them; and other shells that are generically compatible with the original sh like ash, dash, heirloom sh, etc., through a universal script that automatically optimizes its functions depending on the features the shell can provide.
[Fowarded example]
start.sh
This is an optional starter script. Placing the startup methods here is just a convenience and can be placed in the main script instead. This script is also not needed if the scripts are to be compiled.
#!/bin/sh
# load loader.sh
. loader.sh
# include directories to search path
loader_addpath /usr/lib/sh deps source
# load main script
load main.sh
main.sh
include a.sh
include b.sh
echo '---- main.sh ----'
# remove loader from shellspace since
# we no longer need it
loader_finish
# main procedures go from here
# ...
a.sh
include main.sh
include a.sh
include b.sh
echo '---- a.sh ----'
b.sh
include main.sh
include a.sh
include b.sh
echo '---- b.sh ----'
output:
---- b.sh ----
---- a.sh ----
---- main.sh ----
What's best is scripts based on it may also be compiled to form a single script with the available compiler.
Here's a project that uses it: http://sourceforge.net/p/playshell/code/ci/master/tree/. It can run portably with or without compiling the scripts. Compiling to produce a single script can also happen, and is helpful during installation.
I also created a simpler prototype for any conservative party that may want to have a brief idea of how an implementation script works: https://sourceforge.net/p/loader/code/ci/base/tree/loader-include-prototype.bash. It's small and anyone can just include the code in their main script if they want to if their code is intended to run with Bash 4.0 or newer, and it also doesn't use eval
.
Same pdo error in sql query while trying to insert into database value from multidimential array:
$sql = "UPDATE test SET field=arr[$s][a] WHERE id = $id";
$sth = $db->prepare($sql);
$sth->execute();
Extracting array arr[$s][a]
from sql query, using instead variable containing it fixes the problem.
.toString()
is available, or just add ""
to the end of the int
var x = 3,
toString = x.toString(),
toConcat = x + "";
Angular is simply JavaScript at the core.
Just give full path to exclusion file: eg..
-- no - - - - -xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\list-of-excluded-files.txt
In this example the file would be located " C:\list-of-excluded-files.txt "
or...
correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\mybatch\list-of-excluded-files.txt
In this example the file would be located " C:\mybatch\list-of-excluded-files.txt "
Full path fixes syntax error.
I had the same issue with missing references. Below my scenario:
All version numbers in project and packages match, doing nuget restore (in all its ways) did not work.
How I fixed it: simply delete the package folders in the solution root and execute nuget restore. At this point the dlls are correctly downloaded and can be added for the missing references.
In my opinion, it would be a cleaner and easier solution to just set a class on the body and set the font-family in css according to that class.
don't know if that's an option in your case though.
__init__

Use git rm
.
If you want to remove the file from the Git repository and the filesystem, use:
git rm file1.txt
git commit -m "remove file1.txt"
But if you want to remove the file only from the Git repository and not remove it from the filesystem, use:
git rm --cached file1.txt
git commit -m "remove file1.txt"
And to push changes to remote repo
git push origin branch_name
In PyCharm the parameters are added in the Script Parameters
as you did but, they are enclosed in double quotes ""
and without specifying the Interpreter flags like -s
. Those flags are specified in the Interpreter options
box.
Script Parameters box contents:
"file1.txt" "file2.txt"
Interpeter flags:
-s
Or, visually:
Then, with a simple test file to evaluate:
if __name__ == "__main__":
import sys
print(sys.argv)
We get the parameters we provided (with sys.argv[0]
holding the script name of course):
['/Path/to/current/folder/test.py', 'file1.txt', 'file2.txt']
Each project in Visual Studio has a "treat warnings as errors" option. Go through each of your projects and change that setting:
The location of this switch varies, depending on the type of project (class library vs. web application, for example).
The use of http.createClient

var results = '';
var req = http.request(options, function(res) {

//TODO
});
res.on('end', function () {
//TODO
});
});
req.on('error', function(e) {
//TODO

req.end();
If you have a collection in your model and your View is strongly type, some variation of this will work:
@Html.DropDownListFor(x => x.RegionID,
new SelectList(Model.Regions,"RegionID", "RegionName", Model.RegionID))
-or-
@Html.DropDownList("RegionID",

Use insert batch in codeigniter to insert multiple row of data.

A solution, can be:
with open("file", "r") as fd:
lines = fd.read().splitlines()
You get the list of lines without "\r\n" or "\n".
Or, use the classic way:
with open("file", "r") as fd:
for line in fd:
line = line.strip()
You read the file, line by line and drop the spaces and newlines.
If you only want to drop the newlines:
with open("file", "r") as fd:
for line in fd:
line = line.replace("\r", "").replace("\n", "")
Et voilà.
Note: The behavior of Python 3 is a little different. To mimic this behavior, use io.open
.
See the documentation of io.open.
So, you can use:
with io.open("file", "r", newline=None) as fd:
for line in fd:
line = line.replace("\n", "")
When the newline parameter is None
: lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n'.
newline controls how universal newlines works (it only applies to text mode). It can be None, '', '\n', '\r', and '\r\n'. It works as follows:
On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in '\n', '\r', or '\r\n', and these are translated into '\n' before being returned to the caller. If it is '', universal newlines mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated.

$osm = new COM("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.\n");
//Set the application to remain hidden to avoid flashing the document onscreen

//Launch the desktop
$oDesktop = $osm->createInstance("com.sun.star.frame.Desktop");
//Load the .doc file, and pass in the "Hidden" property from above
$oWriterDoc = $oDesktop->loadComponentFromURL($doc_url,"_blank", 0, $args);
//Set up the arguments for the PDF output
$export_args = array(MakePropertyValue("FilterName","writer_pdf_Export",$osm));
//print_r($export_args);

Also another important note. You have to set android.permission.ACCESS_NETWORK_STATE
in your AndroidManifest.xml for this to work.
_ how could I have found myself the information I needed in the online documentation?

Really great question :-) I used solution similar to Mr.Ferguson`s sometime ago. Our decompiled enum looks like this:
final class BonusType extends Enum
{
private BonusType(String s, int i, int id)
{
super(s, i);
this.id = id;
}
public static BonusType[] values()
{
BonusType abonustype[];
int i;
BonusType abonustype1[];
System.arraycopy(abonustype = ENUM$VALUES, 0, abonustype1 = new BonusType[i = abonustype.length], 0, i);
return abonustype1;
}
public static BonusType valueOf(String s)
{
return (BonusType)Enum.valueOf(BonusType, s);
}
public static final BonusType MONTHLY;
public static final BonusType YEARLY;
public static final BonusType ONE_OFF;
public final int id;
private static final BonusType ENUM$VALUES[];
static
{
MONTHLY = new BonusType("MONTHLY", 0, 1);
YEARLY = new BonusType("YEARLY", 1, 2);
ONE_OFF = new BonusType("ONE_OFF", 2, 3);
ENUM$VALUES = (new BonusType[] {
MONTHLY, YEARLY, ONE_OFF
});
}
}
Seeing this is apparent why ordinal()
is unstable. It is the i
in super(s, i);
. I'm also pessimistic that you can think of a more elegant solution than these you already enumerated. After all enums are classes as any final classes.
To find all the matching strings, use String's scan
method.
str = "A 54mpl3 string w1th 7 numb3rs scatter36 ar0und"
str.scan(/\d+/)
#=> ["54", "3", "1", "7", "3", "36", "0"]
If you want, MatchData
, which is the type of the object returned by the Regexp match
method, use:
str.to_enum(:scan, /\d+/).map { Regexp.last_match }
#=> [#<MatchData "54">, #<MatchData "3">, #<MatchData "1">, #<MatchData "7">, #<MatchData "3">, #<MatchData "36">, #<MatchData "0">]
The benefit of using MatchData
is that you can use methods like offset
:
match_datas = str.to_enum(:scan, /\d+/).map { Regexp.last_match }
match_datas[0].offset(0)
#=> [2, 4]
match_datas[1].offset(0)
#=> [7, 8]

The problem occurred because of wrong table type.MyISAM is the only type of table that Mysql supports for Full-text indexes.
To correct this error run following sql.
CREATE TABLE gamemech_chat (

from_userid varchar(50) NOT NULL default '0',
to_userid varchar(50) NOT NULL default '0',
text text NOT NULL,
systemtext text NOT NULL,

PRIMARY KEY (id),
KEY from_userid (from_userid),
FULLTEXT KEY from_userid_2 (from_userid),
KEY chatroom (chatroom),
KEY timestamp (timestamp)
) ENGINE=MyISAM;

Are you sure that the function exists as a function and under the dbo schema?
There are all sorts of things you can look out for, but it doesn't really give you any certainty as to the technology behind a site. In general, information like that is something people will want to hide, as the more information that is exposed the easier it might be for malicious parties to identify security vulnerabilities or denial of service holes.
If I was interested I'd probably look, in no particular order, at:
Incidentally, the tools mentioned in other answers are only looking at some of the above properties of the site for you, albeit automatically, and slightly quicker. :)
Late answer, I know, but for me the following script is quite useful - and it answers the question too, hitting two flys with one flag ;-)
The following script expands SendTo in the file explorer's context menu:
@echo off
cls
if "%~dp1"=="" goto Install
REM change drive, then cd to path given and run shell there
%~d1
cd "%~dp1"
cmd /k
goto End
:Install
rem No arguments: Copies itself into SendTo folder
copy "%0" "%appdata%\Microsoft\Windows\SendTo\A - Open in CMD shell.cmd"
:End
If you run this script without any parameters by double-clicking on it, it will copy itself to the SendTo folder and renaming it to "A - Open in CMD shell.cmd". Afterwards it is available in the "SentTo" context menu.
Then, right-click on any file or folder in Windows explorer and select "SendTo > A - Open in CMD shell.cmd"
The script will change drive and path to the path containing the file or folder you have selected and open a command shell with that path - useful for Visual Studio Code, because then you can just type "code ." to run it in the context of your project.
How does it work?
%0
- full path of the batch script
%~d1
- the drive contained in the first argument (e.g. "C:")
%~dp1
- the path contained in the first argument
cmd /k
- opens a command shell which stays open
Not used here, but %~n1
is the file name of the first argument.
I hope this is helpful for someone.
Ajax forms work asynchronously using Javascript. So it is required, to load the script files for execution. Even though it's a small performance compromise, the execution happens without postback.
We need to understand the difference between the behaviours of both Html and Ajax forms.
Ajax:
Won't redirect the form, even you do a RedirectAction().
Will perform save, update and any modification operations asynchronously.
Html:
Will redirect the form.
Will perform operations both Synchronously and Asynchronously (With some extra code and care).
Demonstrated the differences with a POC in below link. Link
Either write a class that implements Runnable, and pass whatever you need in a suitably defined constructor, or write a class that extends Thread with a suitably defined constructor that calls super() with appropriate parameters.
const FindDate = (date, allDate) => {
// moment().diff only works on moment(). Make sure both date and elements in allDate array are in moment format
let nearestDate = -1;
allDate.some(d => {
const currentDate = moment(d)
const difference = currentDate.diff(d); // Or d.diff(date) depending on what you're trying to find
if(difference >= 0){
nearestDate = d
}
});
console.log(nearestDate)
}
No this step isn't equal to downloading the laravel.zip by using the command composer create-project laravel/laravel laravel you actually download the laravel project as well as dependent packages so its one step ahead.
If you are using windows environment you can solve the problem by deleting the composer environment variable you created to install the composer. And this command will run properly.
It doesn't seem like you can access this in browser. The search input is a Webkit HTML wrapper for the Cocoa NSSearchField. The cancel button seems to be contained within the browser client code with no external reference available from the wrapper.
Sources:
Looks like you'll have to figure it out through mouse position on click with something like:
$('input[type=search]').bind('click', function(e) {
var $earch = $(this);
var offset = $earch.offset();
if (e.pageX > offset.left + $earch.width() - 16) { // X button 16px wide?
// your code here
}
});
In my case, that support libraries for ConstraintLayout were installed, but I was adding the incorrect version of ConstraintLayout Library in my build.gradle file. In order to see what version have you installed, go to Preferences
> Appearance & Behavior
> System Settings
> Android SDK
. Now, click on SDK Tools
tab in right pane. Check Show Package Details and take note of the version.
Finally you can add the correct version in the build.gradle
file
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9'
testCompile 'junit:junit:4.12'
}
Here is something you can do with a two step approach and awk:
A=http://www.suepearson.co.uk/product/174/71/3816/
echo $A|awk '
{
var=gensub(///,"||",3,$0) ;
sub(/\|\|.*/,"",var);
print var
}'
Output: http://www.suepearson.co.uk
Hope that helps!
Sounds like you're expecting size_t
to be the same as unsigned long
(possibly 64 bits) when it's actually an unsigned int
(32 bits). Try using %zu
in both cases.
I'm not entirely certain though.
Add /usr/local/share/npm/bin/

Sometimes if it is a new server you need to configure or install ASP.NET feature on IIS for it to be able to read your web.config file.
In my case this was the reason.
Do it like this:
Go to Settings -> General -> Profiles - tap on your Profile - tap on the Trust button.
but iOS10 has a little change,
Users should go to Settings - General - Device Management - tap on your Profile - tap on Trust button.

Got it! I found an idea here
http://www.mail-archive.com/[email protected]/msg18410.html
In this example, they loaded a blank popup window into an object, cloned the contents of the element to be displayed, and appended it to the body of the object. Since I already knew what the contents of view-details (or any page I load in the lightbox), I just had to clone that content instead and load it into an object. Then, I just needed to print that object. The final outcome looks like this:
$('.printBtn').bind('click',function() {
var thePopup = window.open( '', "Customer Listing", "menubar=0,location=0,height=700,width=700" );
$('#popup-content').clone().appendTo( thePopup.document.body );
thePopup.print();
});
I had one small drawback in that the style sheet I was using in view-details.php was using a relative link. I had to change it to an absolute link. The reason being that the window didn't have a URL associated with it, so it had no relative position to draw on.
Works in Firefox. I need to test it in some other major browsers too.
I don't know how well this solution works when you're dealing with images, videos, or other process intensive solutions. Although, it works pretty well in my case, since I'm just loading tables and text values.
Thanks for the input! You gave me some ideas of how to get around this.
For column types Rails supports out of the box - like the string in this question - the best approach is to set the column default in the database itself as Daniel Kristensen indicates. Rails will introspect on the DB and initialize the object accordingly. Plus, that makes your DB safe from somebody adding a row outside of your Rails app and forgetting to initialize that column.
For column types Rails doesn't support out of the box - e.g. ENUM columns - Rails won't be able to introspect the column default. For these cases you do not want to use after_initialize (it is called every time an object is loaded from the DB as well as every time an object is created using .new), before_create (because it occurs after validation), or before_save (because it occurs upon update too, which is usually not what you want).
Rather, you want to set the attribute in a before_validation on: create, like so:
before_validation :set_status_because_rails_cannot, on: :create
def set_status_because_rails_cannot
self.status ||= 'P'
end
another solution using dplyr is:
df <- ## your data ##
df <- df %>%
mutate(Den = ifelse(any(is.na(Den)) | any(Den != 1), 0, 1))
Funny enough, a same problem I just met, and I get this work in following way:
combining with linux command ln
, we can make thing a lot simper:
1. cd Proj/Client
2. ln -s ../Common ./
3. cd Proj/Server
4. ln -s ../Common ./
And, now if you want to import some_stuff
from file: Proj/Common/Common.py
into your file: Proj/Client/Client.py
, just like this:
# in Proj/Client/Client.py
from Common.Common import some_stuff
And, the same applies to Proj/Server
, Also works for setup.py
process,

arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);

Sure. Add an Axes
using add_subplot
. (Edited import
.) (Edited show
.)
import matplotlib.pyplot as plt
f1 = plt.figure()
f2 = plt.figure()
ax1 = f1.add_subplot(111)
ax1.plot(range(0,10))
ax2 = f2.add_subplot(111)
ax2.plot(range(10,20))
plt.show()
Alternatively, use add_axes
.
ax1 = f1.add_axes([0.1,0.1,0.8,0.8])
ax1.plot(range(0,10))
ax2 = f2.add_axes([0.1,0.1,0.8,0.8])
ax2.plot(range(10,20))

Use the CSS below, the first declaration will ensure your table sticks to the widths you provide (you'll need to add the classes in your HTML):
table{
table-layout:fixed;
}
th.from, th.date {
width: 15%;
}
th.subject{
width: 70%;
}
Should work:
.attr({
target:"nw",
title:"Opens in a new window",
"data-value":"internal link" // attributes which contain dash(-) should be covered in quotes.
});
Note:
" When setting multiple attributes, the quotes around attribute names are optional.
WARNING: When setting the 'class' attribute, you must always use quotes!
From the jQuery documentation (Sep 2016) for .attr:
Attempting to change the type attribute on an input or button element created via document.createElement() will throw an exception on Internet Explorer 8 or older.
Edit:
For future reference...
To get a single attribute you would use
var strAttribute = $(".something").attr("title");
To set a single attribute you would use
$(".something").attr("title","Test");
To set multiple attributes you need to wrap everything in { ... }
$(".something").attr( { title:"Test", alt:"Test2" } );
You will need to use prop()
as of jQuery 1.6+
the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.
...the most important concept to remember about the checked attribute is that it does not correspond to the checked property. The attribute actually corresponds to the defaultChecked property and should be used only to set the initial value of the checkbox. The checked attribute value does not change with the state of the checkbox, while the checked property does
So to get the checked status of a checkbox, you should use:
$('#checkbox1').prop('checked'); // Returns true/false
Or to set the checkbox as checked or unchecked you should use:
$('#checkbox1').prop('checked', true); // To check it
$('#checkbox1').prop('checked', false); // To uncheck it
Have you considered doing this from the layout.xml
? You could set for your ImageView
the ScaleType to android:scaleType="centerCrop"
and set the dimensions of the image in the ImageView
inside the layout.xml
.
Use below code to generate files on fly..
<? //Generate text file on the fly
header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=savethis.txt");
// do your Db stuff here to get the content into $content
print "This is some text...\n";
print $content;
?>
is
is generally preferred when comparing arbitrary objects to singletons like None
because it is faster and more predictable. is
always compares by object identity, whereas what ==
will do depends on the exact type of the operands and even on their ordering.
This recommendation is supported by PEP 8, which explicitly states that "comparisons to singletons like None should always be done with is
or is not
, never the equality operators."
To go to location WITH PIN on it, use:
String uri = "http://maps.google.com/maps?q=loc:" + destinationLatitude + "," + destinationLongitude;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);
for without pin, use this in uri:
String uri = "geo:" + destinationLatitude + "," + destinationLongitude;
You can also use pathlib
.
from pathlib2 import Path
path = Path(file_to_search)
text = path.read_text()
text = text.replace(text_to_search, replacement_text)
path.write_text(text)

Maybe this is useful to anyone in the future, I have implemented a custom Authorize Attribute like this:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class ClaimAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
private readonly string _claim;
public ClaimAuthorizeAttribute(string Claim)
{
_claim = Claim;
}
public void OnAuthorization(AuthorizationFilterContext context)
{
var user = context.HttpContext.User;
if(user.Identity.IsAuthenticated && user.HasClaim(ClaimTypes.Name, _claim))
{
return;
}
context.Result = new ForbidResult();
}
}
if ($name ) { #since undef and '' both evaluate to false #this should work only when string is defined and non-empty... #unless you're expecting someting like $name="0" which is false. #notice though that $name="00" is not false }
Your mock is raising the exception just fine, but the error.resp.status
value is missing. Rather than use return_value
, just tell Mock
that status
is an attribute:
barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
Additional keyword arguments to Mock()
are set as attributes on the resulting object.
I put your foo
and bar
definitions in a my_tests
module, added in the HttpError
class so I could use it too, and your test then can be ran to success:
>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
... barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
... result = my_test.foo()
...
404 -
>>> result is None
True
You can even see the print '404 - %s' % error.message
line run, but I think you wanted to use error.content
there instead; that's the attribute HttpError()
sets from the second argument, at any rate.

}
The .git folder is only stored in the root directory of the repo, not all the sub-directories like subversion. You should be able to just delete that one folder, unless you are using Submodules...then they will have one too.
To answer this point:
I want Sleep to be an async method so it can await other methods
you can maybe rewrite the Sleep
function like this:
private static async Task<int> Sleep(int ms)
{
Console.WriteLine("Sleeping for " + ms);
var task = Task.Run(() => Thread.Sleep(ms));
await task;
Console.WriteLine("Sleeping for " + ms + "END");
return ms;
}
static void Main(string[] args)
{
Console.WriteLine("Starting");
var task1 = Sleep(2000);
var task2 = Sleep(1000);
int totalSlept = task1.Result +task2.Result;
Console.WriteLine("Slept for " + totalSlept + " ms");
Console.ReadKey();
}
running this code will output :
Starting
Sleeping for 2000
Sleeping for 1000
*(one second later)*
Sleeping for 1000END
*(one second later)*
Sleeping for 2000END
Slept for 3000 ms
The problem with your code is in your loop in Check_Circular. You are advancing through the list using n1 by going one node at a time. By reassigning n2 to n2.next.next you are advancing through it two at a time.
When you do that, n2.next.next may be null, so n2 will be null after the assignment. When the loop repeats and it checks if n2.next is not null, it throws the NPE because it can't get to next since n2 is already null.
You want to do something like what Alex posted instead.
Note that following gnarf's idea you can also do:
var js = "alert('B:' + this.id); return false;";<br/>
var newclick = eval("(function(){"+js+"});");<br/>
$("a").get(0).onclick = newclick;
That will set the onclick without triggering the event (had the same problem here and it took me some time to find out).
I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.
What is the proper #include for the function 'sleep()'?
sleep()
isn't Standard C, but POSIX so it should be:
#include <unistd.h>
You can't databind to a property and then explictly assign a value to the databound property.

Update:
As of MySQL 5.7 you can use DROP USER IF EXISTS
statement.
Ref: https://dev.mysql.com/doc/refman/5.7/en/drop-user.html
Syntax:
DROP USER [IF EXISTS] user [, user] ...
Example:
DROP USER IF EXISTS 'jeffrey'@'localhost';
FYI (and for older version of MySQL), this is a better solution...!!!
The following SP will help you to remove user 'tempuser'@'%'
by executing CALL DropUserIfExistsAdvanced('tempuser', '%');
If you want to remove all users named 'tempuser'
(say 'tempuser'@'%'
, 'tempuser'@'localhost'
and 'tempuser'@'192.168.1.101'
) execute SP like CALL DropUserIfExistsAdvanced('tempuser', NULL);
This will delete all users named tempuser
!!! seriously...
Now please have a look on mentioned SP DropUserIfExistsAdvanced
:
DELIMITER $$
DROP PROCEDURE IF EXISTS `DropUserIfExistsAdvanced`$$
CREATE DEFINER=`root`@`localhost` PROCEDURE `DropUserIfExistsAdvanced`(
MyUserName VARCHAR(100)
, MyHostName VARCHAR(100)
)
BEGIN
DECLARE pDone INT DEFAULT 0;
DECLARE mUser VARCHAR(100);
DECLARE mHost VARCHAR(100);
DECLARE recUserCursor CURSOR FOR
SELECT `User`, `Host` FROM `mysql`.`user` WHERE `User` = MyUserName;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET pDone = 1;
IF (MyHostName IS NOT NULL) THEN
-- 'username'@'hostname' exists
IF (EXISTS(SELECT NULL FROM `mysql`.`user` WHERE `User` = MyUserName AND `Host` = MyHostName)) THEN
SET @SQL = (SELECT mResult FROM (SELECT GROUP_CONCAT("DROP USER ", "'", MyUserName, "'@'", MyHostName, "'") AS mResult) AS Q LIMIT 1);
PREPARE STMT FROM @SQL;
EXECUTE STMT;
DEALLOCATE PREPARE STMT;
END IF;
ELSE
-- check whether MyUserName exists (MyUserName@'%' , MyUserName@'localhost' etc)
OPEN recUserCursor;
REPEAT
FETCH recUserCursor INTO mUser, mHost;
IF NOT pDone THEN
SET @SQL = (SELECT mResult FROM (SELECT GROUP_CONCAT("DROP USER ", "'", mUser, "'@'", mHost, "'") AS mResult) AS Q LIMIT 1);
PREPARE STMT FROM @SQL;
EXECUTE STMT;
DEALLOCATE PREPARE STMT;
END IF;
UNTIL pDone END REPEAT;
END IF;
FLUSH PRIVILEGES;
END$$
DELIMITER ;
Usage:
CALL DropUserIfExistsAdvanced('tempuser', '%');
to remove user 'tempuser'@'%'
CALL DropUserIfExistsAdvanced('tempuser', '192.168.1.101');
to remove user 'tempuser'@'192.168.1.101'
CALL DropUserIfExistsAdvanced('tempuser', NULL);
to remove all users named 'tempuser'
(eg., say 'tempuser'@'%'
, 'tempuser'@'localhost'
and 'tempuser'@'192.168.1.101'
)
The table.tostring
metehod of metalua is actually very complete. It deals with nested tables, the indentation level is changeable, ...

This is to supplement zerkms's answer.
To pass data across language barriers, you would need a way to represent the data as a string by serializing the data. One of the serialization methods for JavaScript is JSON. In zerkms's example, the code would be placed inside of an aspx page. To combine his example and yours together on one aspx page, you would have,
<%
int[] numbers = new int[5];
// Fill up numbers...
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
%>
somewhere later on the aspx page
<script type="text/javascript">
var jsVariable = <%= serializer.Serialize(numbers) %>;
</script>
This answer though, assumes that you are generating JavaScript from the initial page load. As per the comments in your post, this could have been done via AJAX. In that case, you would have the server respond with the result of the serialization and then deserialize it in JavaScript using your favorite framework.
Note: Also do not mark this as an answer since I wanted the syntax highlighting to make another answer more clear.
