If you face with the problem at the first time installing Android Studio on your computer.
mklink /D "c:\Android-Sdk" "C:\Users\ **YOUR-USERNAME** \AppData\Local\Android\sdk"
Go to "C:\Users\ YOUR-USERNAME \AppData\Local\" path and create Android\sdk folders inside it.
After that you can continue installation.
I use @Thiho answer but i get this error:
'git' is not recognized as an internal or external command
For solving that i use this steps:
I add the following paths to PATH:
C:\Program Files\Git\bin\
C:\Program Files\Git\cmd\
In windows 7:
Finally close and re-open your console.
Demo : http://jsfiddle.net/NbGBj/
$("document").ready(function(){
$("#upload").change(function() {
alert('changed!');
});
});
Copy the file into your src folder. Go to the Project Explorer in Eclipse, Right-click on your project, and click on "Refresh". The file should appear on the Project Explorer pane as well.
Use the command as
java -classpath ".;C:\MyLibs\a\*;D:\MyLibs\b\*" <your-class-name>
The above command will set the mentioned paths to classpath only once for executing the class named TestClass.
If you want to execute more then one classes, then you can follow this
set classpath=".;C:\MyLibs\a\*;D:\MyLibs\b\*"
After this you can execute as many classes as you want just by simply typing
java <your-class-name>
The above command will work till you close the command prompt. But after closing the command prompt, if you will reopen the command prompt and try to execute some classes, then you have to again set the classpath with the help of any of the above two mentioned methods.(First method for executing one class and second one for executing more classes)
If you want to set the classpth only once so that it could work for everytime, then do as follows
1. Right click on "My Computer" icon
2. Go to the "properties"
3. Go to the "Advanced System Settings" or "Advance Settings"
4. Go to the "Environment Variable"
5. Create a new variable at the user variable by giving the information as below
a. Variable Name- classpath
b. Variable Value- .;C:\program files\jdk 1.6.0\bin;C:\MyLibs\a\';C:\MyLibs\b\*
6.Apply this and you are done.
Remember this will work every time. You don't need to explicitly set the classpath again and again.
NOTE: If you want to add some other libs after some day, then don't forget to add a semi-colon at the end of the "variable-value" of the "Environment Variable" and then type the path of your new libs after the semi-colon. Because semi-colon separates the paths of different directories.
Hope this will help you.
I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.
A Git repository doesn't have a name. You can just rename the directory containing your worktree if you want.
Suppose we have column with alphanumeric field having entries like
a41q
1458
xwe8
1475
asde
9582
.
.
.
.
.
qe84
and you want highest numeric value from this db column (in this case it is 9582) then this query will help you
SELECT Max(column_name) from table_name where column_name REGEXP '^[0-9]+$'
If you want to keep the database between uninstalls you have to put it on the SD Card. This is the only place that won't be deleted at the moment your app is deleted. But in return it can be deleted by the user every time.
If you put your DB on the SD Card you can't use the SQLiteOpenHelper anymore, but you can use the source and the architecture of this class to get some ideas on how to implement the creation, updating and opening of a databse.
I'm a complete noob on Entity but this is how I would do it in theory...
var name = yourDbContext.MyTable.Find(1).Name;
If It's A Primary Key.
-- OR --
var name = yourDbContext.MyTable.SingleOrDefault(mytable => mytable.UserId == 1).Name;
-- OR --
For whole Column:
var names = yourDbContext.MyTable
.Where(mytable => mytable.UserId == 1)
.Select(column => column.Name); //You can '.ToList();' this....
But "oh Geez Rick, What do I know..."
Delete the datanode under your hadoop folder then rerun start-all.sh
The answers mentioning adding @Transactional
are correct, but for simplicity you could just have your test class extends AbstractTransactionalJUnit4SpringContextTests
.
First, understand that you have three languages working together:
PHP: It only runs by the server and responds to requests like clicking on a link (GET) or submitting a form (POST).
HTML & JavaScript: It only runs in someone's browser (excluding NodeJS).
I'm assuming your file looks something like:
<!DOCTYPE HTML>
<html>
<?php
function runMyFunction() {
echo 'I just ran a php function';
}
if (isset($_GET['hello'])) {
runMyFunction();
}
?>
Hello there!
<a href='index.php?hello=true'>Run PHP Function</a>
</html>
Because PHP only responds to requests (GET, POST, PUT, PATCH, and DELETE via $_REQUEST), this is how you have to run a PHP function even though they're in the same file. This gives you a level of security, "Should I run this script for this user or not?".
If you don't want to refresh the page, you can make a request to PHP without refreshing via a method called Asynchronous JavaScript and XML (AJAX).
That is something you can look up on YouTube though. Just search "jquery ajax"
I recommend Laravel to anyone new to start off right: http://laravel.com/
I had this same problem, but I'm a Linux user.
I resolved the problem by reattempting the installation with adminstrator privileges. [For those Linux users reading this, I ran studio.sh
with sudo
.]
The default visibility (no keyword) is package which means that it will be available to every class that is located in the same package.
Interesting side note is that protected doesn't limit visibility to the subclasses but also to the other classes in the same package
You must include jQuery in the project.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
I didn't find any doc about this so I just opened a random code example from tutorialrepublic.com http://www.tutorialrepublic.com/twitter-bootstrap-tutorial/bootstrap-dropdowns.php
Hope this helps someone else.
UITableViewCell
has an attribute multipleSelectionBackgroundView
.
https://developer.apple.com/documentation/uikit/uitableviewcell/1623226-selectedbackgroundview
Just create an UIView
define the .backgroundColor
of your choice and assign it to your cells .multipleSelectionBackgroundView
attribute.
sessionStorage
is the same as localStorage
, except that it stores the data for only one session, and it will be removed when the user closes the browser window that created it.
After lots of struggle I found here you go:
$cfg['blowfish_secret'] = ''; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
830bbca930d5e417ae4249931838e2c70ca0365044268fa0ede75e33aff677de
$cfg['blowfish_secret'] = '830bbca930d5e417ae4249931838e2c70ca0365044268fa0ede75e33aff677de
';
I found this when I was downloading updated version of phpmyadmin. I wish this solution help you.
You can also remove the line
require: 'ngModel',
if you don't need ngModel
in this directive. Removing ngModel
will allow you to make a directive without thatngModel
error.
You need the first and last parentheses. Use something like this:
str.indexOf('('); - it will give you first occurrence
str.lastIndexOf(')'); - last one
So you need a string between,
String searchedString = str.substring(str1.indexOf('('),str1.lastIndexOf(')');
Target= "_blank"
This does it in html, give it a try in C#
You could compare the two values right after splitting them with ':'.
While using regex is typically less performant than non-regex techniques, I do appreciate the control and flexibility that it affords.
In my snippet, I will set the pattern to be case-insensitive (\i
, although my sample input will not challenge this rule) and include word boundaries (\b
, although they were not explicitly called for).
I am also going to use the \K
metacharacter to reset the fullstring match so that no capture groups / backreferences are needed.
Code: (Demo)
$search = 'The';
$replace = 'A';
$subject = "The Quick Brown Fox Jumps Over The Lazy Dog's Thermos!";
echo preg_replace(
'/.*\K\b' . preg_quote($search, '/') . '\b/i',
$replace,
$subject
);
Output:
The Quick Brown Fox Jumps Over A Lazy Dog's Thermos!
# ^^^ ^ ^^^
# not replaced replaced not replaced
Without word boundaries: (Demo)
echo preg_replace(
'/.*\K' . preg_quote($search, '/') . '/i',
$replace,
$subject
);
Output:
The Quick Brown Fox Jumps Over The Lazy Dog's Armos!
# ^^^ ^^^ ^
# not replaced not replaced replaced

There are few modes to open file (read, write etc..)
If you want to read from file you should type file = open("File.txt","r")
, if write than file = open("File.txt","w")
. You need to give the right permission regarding your usage.
more modes:
From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":
The following works for me:
python -m http.server [<portNo>]
Because I am using Python 3 the module SimpleHTTPServer
has been replaced by http.server
, at least in Windows.
It means that the callback function you passed to this.dataStore.data.find
should return a boolean and have 3 parameters, two of which can be optional:
However, your callback function does not return anything (returns void). You should pass a callback function with the correct return value:
this.dataStore.data.find((element, index, obj) => {
// ...
return true; // or false
});
or:
this.dataStore.data.find(element => {
// ...
return true; // or false
});
Reason why it's this way: the function you pass to the find
method is called a predicate. The predicate here defines a boolean outcome based on conditions defined in the function itself, so that the find
method can determine which value to find.
In practice, this means that the predicate is called for each item in data
, and the first item in data
for which your predicate returns true
is the value returned by find
.
For me the problem appeared in this situation:
I installed VS2012 and did not need VS2010 anymore. I wanted to get my computer clean and also removed the VS2010 runtime executables, thinking that no other program would use it. Then I wanted to test my DLL by attaching it to a program (let's call it program X). I got the same error message. I thought that I did something wrong when compiling the DLL. However, the real problem was that I attached the DLL to program X, and program X was compiled in VS2010 with debug info. That is why the error was thrown. I recompiled program X in VS2012, and the error was gone.
npx @angular/cli@10 new my-poject
you can replace 10 with your version of choice... no need to uninstall your existing CLI! Just learnt that now...
There is no sudo
command in Windows. The nearest equivalent is "run as administrator."
You can do this using the runas
command with an administrator trust-level, or by right-clicking the program in the UI and choosing "run as administrator."
From the api on GridLayout:
The container is divided into equal-sized rectangles, and one component is placed in each rectangle.
Try using FlowLayout or GridBagLayout for your set size to be meaningful. Also, @Serplat is correct. You need to use setPreferredSize( Dimension ) instead of setSize( int, int ).
JPanel displayPanel = new JPanel();
// JPanel displayPanel = new JPanel( new GridLayout( 4, 2 ) );
// JPanel displayPanel = new JPanel( new BorderLayout() );
// JPanel displayPanel = new JPanel( new GridBagLayout() );
JTextField titleText = new JTextField( "title" );
titleText.setPreferredSize( new Dimension( 200, 24 ) );
// For FlowLayout and GridLayout, uncomment:
displayPanel.add( titleText );
// For BorderLayout, uncomment:
// displayPanel.add( titleText, BorderLayout.NORTH );
// For GridBagLayout, uncomment:
// displayPanel.add( titleText, new GridBagConstraints( 0, 0, 1, 1, 1.0,
// 1.0, GridBagConstraints.CENTER, GridBagConstraints.NONE,
// new Insets( 0, 0, 0, 0 ), 0, 0 ) );

check your R directory ...sometimes if a file name is not all lower case and has special characters you can get this error. Im using eclipse and it only accepts file names a-z0-9_.
Delete all files under the .m2 repository folder and rebuild the project.
You need to open the Service.cs file in the designer, right click it and choose the menu-option "Add Installer".
It won't install right out of the box... you need to create the installer class first.
Some reference on service installer:
How to: Add Installers to Your Service Application
Quite old... but this is what I am talking about:
Windows Services in C#: Adding the Installer (part 3)
By doing this, a ProjectInstaller.cs
will be automaticaly created. Then you can double click this, enter the designer, and configure the components:
serviceInstaller1
has the properties of the service itself: Description
, DisplayName
, ServiceName
and StartType
are the most important.
serviceProcessInstaller1
has this important property: Account
that is the account in which the service will run.
For example:
this.serviceProcessInstaller1.Account = ServiceAccount.LocalSystem;
If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec()
approach. Here is a simple example:
<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";
$connStr =
'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';
$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql =
"SELECT AgentName FROM Agents " .
"WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);
// query parameter value(s)
$params = array(
5,
'Homer'
);
$sth->execute($params);
while ($row = $sth->fetch()) {
echo $row['AgentName'] . "\r\n";
}
NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF
. If you do need to support such characters then neither PDO_ODBC
nor the old odbc_
functions will work; you'll need to use the solution described in this answer.
A further note on Dmitry's 2017 answer. I opened up
C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\MSBuild\Microsoft\VisualStudio\Managed\
Microsoft.CSharp.DesignTime.targets
and went to the <ProjectCapability>
element. I already had this:
<ProjectCapability Include="
CSharp;
Managed;
ClassDesigner**;**" />
with ClassDesigner already there, and yet I was still unable to drag items to my hack-made Diagram.cd using the XML editing method Dmitry mentioned (
Manually create text file, say MyClasses.cd with following content:
<?xml version="1.0" encoding="utf-8"?> <ClassDiagram MajorVersion="1"
> MinorVersion="1">
> <Font Name="Segoe UI" Size="9" /> </ClassDiagram>
). But when I took off the semicolon off 'ClassDesigner' in that element then reopened Visual Studio, voila, I was able to drag classes from my Solution Explorer to my Diagram.cd window.
So in conclusion, this element in Microsoft.CSharp.DesignTime.targets
worked:
<ProjectCapability Include="
CSharp;
Managed;
ClassDesigner" />
I am using VS 2019, version 16.1.5.
To make sure the height of a view is 50% of the screen then we can create two sub LinearLayouts in a LinearLayout. Each of the child LinearLayout should have "android:layout_weight" of 0.5 to cover half the screen
the parent LinearLAyout should have "android:orientation" set to vertical
.
.
here is code for your reference.... this code contains two buttons of height half the screen
<LinearLayout
android:orientation="vertical"
android:layout_height="match_parent">
<LinearLayout
android:layout_weight="0.5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:padding="10dp"
android:layout_weight="0.5"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="button1"
android:id="@+id/button1"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true"
/>
<Button
android:padding="10dp"
android:layout_weight="0.5"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="button2"
android:id="@+id/button2"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
/>

Try handling the change event of the select
and using this.value
to determine whether it's 'Yes' or not.
JS
document.getElementById('test').addEventListener('change', function () {
var style = this.value == 1 ? 'block' : 'none';
document.getElementById('hidden_div').style.display = style;
});
HTML
<select id="test" name="form_select">
<option value="0">No</option>
<option value ="1">Yes</option>
</select>
<div id="hidden_div" style="display: none;">Hello hidden content</div>
Your syntax is incorrect, you should pass the value as the second parameter:
jQuery(this).prev("li").attr("id","newId");
You're comparing apples to oranges here:
webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service
basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.
So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).
Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:
basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security
wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network
For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding
You can do the entire conversion in one line, using the following code:
String number = "1000500000.574";
String convertedString = new DecimalFormat("#,###.##").format(Double.parseDouble(number));
The last two # signs in the DecimalFormat constructor can also be 0s. Either way works.
json_decode()
will return an object or array if second value it's true:
$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];
ES6 version that return the first #text node content
const extract = (node) => {
const text = [...node.childNodes].find(child => child.nodeType === Node.TEXT_NODE);
return text && text.textContent.trim();
}
If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").
df = df.fillna('')
or just
df.fillna('', inplace=True)
This will fill na's (e.g. NaN's) with ''
.
If you want to fill a single column, you can use:
df.column1 = df.column1.fillna('')
One can use df['column1']
instead of df.column1
.
Do it in simple. According to documentation https://developer.android.com/training/data-storage/files
String imageName = "IMG_" + String.valueOf(System.currentTimeMillis()) +".jpg";
picFile = new File(ProfileActivity.this.getCacheDir(),imageName);
and delete it after usage
picFile.delete()
For those looking for an example of how to pass the OAuth2 authorization (access token) in the header (as opposed to using a request or body parameter), here is how it's done:
Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42
An attribute is an instance variable.
Since PostgreSQL 9.1 there is the convenient FOREACH
:
DO
$do$
DECLARE
m varchar[];
arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
FOREACH m SLICE 1 IN ARRAY arr
LOOP
RAISE NOTICE 'another_func(%,%)',m[1], m[2];
END LOOP;
END
$do$
Solution for older versions:
DO
$do$
DECLARE
arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
LOOP
RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
END LOOP;
END
$do$
Also, there is no difference between varchar[]
and varchar[][]
for the PostgreSQL type system. I explain in more detail here.
The DO
statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql
is the default (so you can omit the declaration).
The answer to "Any idea for getting all attributes at once?" question is just to call function with only product id:
$array=get_post_meta($product->id);
key is optional, see http://codex.wordpress.org/Function_Reference/get_post_meta
// 2 dimensional array of arrays of Ints
var arr = [[Int]]()
OR:
// 2 dimensional array of arrays of Ints
var arr: [[Int]] = []
OR if you need an array of predefined size (as mentioned by @0x7fffffff in comments):
// 2 dimensional array of arrays of Ints set to 0. Arrays size is 10x5
var arr = Array(count: 3, repeatedValue: Array(count: 2, repeatedValue: 0))
// ...and for Swift 3+:
var arr = Array(repeating: Array(repeating: 0, count: 2), count: 3)
arr[0][1] = 18
OR
let myVar = 18
arr[0][1] = myVar
arr[1] = [123, 456, 789]
OR
arr[0] += 234
OR
arr[0] += [345, 678]
If you had 3x2 array of 0(zeros) before these changes, now you have:
[
[0, 0, 234, 345, 678], // 5 elements!
[123, 456, 789],
[0, 0]
]
So be aware that sub arrays are mutable and you can redefine initial array that represented matrix.
let a = 0
let b = 1
if arr.count > a && arr[a].count > b {
println(arr[a][b])
}
Remarks: Same markup rules for 3 and N dimensional arrays.
A SELECT INTO
statement creates the table for you. There is no need for the CREATE TABLE
statement before hand.
What is happening is that you create #ivmy_cash_temp1
in your CREATE
statement, then the DB tries to create it for you when you do a SELECT INTO
. This causes an error as it is trying to create a table that you have already created.
Either eliminate the CREATE TABLE
statement or alter your query that fills it to use INSERT INTO SELECT
format.
If you need a unique ID added to your new row then it's best to use SELECT INTO
... since IDENTITY()
only works with this syntax.
This is due because of the items id being the same. On change fires only if a different item id is detected on select.
So you have 2 options: First is to make sure that each items have a unique id when retrieving datas from ajax.
Second is to trigger a rand number at formatSelection for the selected item.
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}
.
formatSelection: function(item) {item.id =getRandomInt(1,200)}
The C# compiler will transform both
for(;;)
{
// ...
}
and
while (true)
{
// ...
}
into
{
:label
// ...
goto label;
}
The CIL for both is the same. Most people find while(true)
to be easier to read and understand. for(;;)
is rather cryptic.
I messed a little more with .NET Reflector, and I compiled both loops with the "Optimize Code" on in Visual Studio.
Both loops compile into (with .NET Reflector):
Label_0000:
goto Label_0000;
You are trying to treat an object as an instance of a class that it is not. It's roughly analogous to trying to press the damper pedal on a guitar (pianos have damper pedals, guitars don't).

Try this one-shot solution that should figure out where ImageMagick is, if you have access to it...
This found all versions on my Godaddy hosting.
Upload this file to your server and call it ImageMagick.php
or something then run it. You will get all the info you need... hopefully...
Good luck.

Then use the code
numpy.random.seed(0)
numpy.random.randint(10, size=5)
This produces the following output:
array([5, 0, 3, 3, 7])
Again,if we run the same code we will get the same result.
Now if we change the seed value 0 to 1 or others:
numpy.random.seed(1)
numpy.random.randint(10, size=5)
This produces the following output: array([5 8 9 5 0])
but now the output not the same like above.
PHP's preg_replace
example:
$str = "motttherbb fffaaattther";
$str = preg_replace("/([a-z])\\1/", "", $str);
echo $str;
Here [a-z]
hits the character, ()
then allows it to be used with \\1
backreference which tries to match another same character (note this is targetting 2 consecutive characters already), thus:
mother father
If you did:
$str = preg_replace("/([a-z])\\1{2}/", "", $str);
that would be erasing 3 consecutive repeated characters, outputting:
moherbb her
Properties prop = new Properties();

Try the following approach:
AutoClosingMessageBox.Show("Text", "Caption", 1000);
Where the AutoClosingMessageBox
class implemented as following:
public class AutoClosingMessageBox {
System.Threading.Timer _timeoutTimer;
string _caption;
AutoClosingMessageBox(string text, string caption, int timeout) {
_caption = caption;
_timeoutTimer = new System.Threading.Timer(OnTimerElapsed,
null, timeout, System.Threading.Timeout.Infinite);
using(_timeoutTimer)
MessageBox.Show(text, caption);
}
public static void Show(string text, string caption, int timeout) {
new AutoClosingMessageBox(text, caption, timeout);
}
void OnTimerElapsed(object state) {
IntPtr mbWnd = FindWindow("#32770", _caption); // lpClassName is #32770 for MessageBox
if(mbWnd != IntPtr.Zero)
SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
_timeoutTimer.Dispose();
}
const int WM_CLOSE = 0x0010;
[System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}
Update: If you want to get the return value of the underlying MessageBox when user selects something before the timeout you can use the following version of this code:
var userResult = AutoClosingMessageBox.Show("Yes or No?", "Caption", 1000, MessageBoxButtons.YesNo);
if(userResult == System.Windows.Forms.DialogResult.Yes) {
// do something
}
...
public class AutoClosingMessageBox {
System.Threading.Timer _timeoutTimer;
string _caption;
DialogResult _result;
DialogResult _timerResult;
AutoClosingMessageBox(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None) {
_caption = caption;
_timeoutTimer = new System.Threading.Timer(OnTimerElapsed,
null, timeout, System.Threading.Timeout.Infinite);
_timerResult = timerResult;
using(_timeoutTimer)
_result = MessageBox.Show(text, caption, buttons);
}
public static DialogResult Show(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None) {
return new AutoClosingMessageBox(text, caption, timeout, buttons, timerResult)._result;
}
void OnTimerElapsed(object state) {
IntPtr mbWnd = FindWindow("#32770", _caption); // lpClassName is #32770 for MessageBox
if(mbWnd != IntPtr.Zero)
SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
_timeoutTimer.Dispose();
_result = _timerResult;
}
const int WM_CLOSE = 0x0010;
[System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}
Yet another Update
I have checked the @Jack's case with YesNo
buttons and discovered that the approach with sending the WM_CLOSE
message does not work at all.
I will provide a fix in the context of the separate AutoclosingMessageBox library. This library contains redesigned approach and, I believe, can be useful to someone.
It also available via NuGet package:
Install-Package AutoClosingMessageBox
Release Notes (v1.0.0.2):

- New Factory() API to provide full control on MessageBox showing;
There might be a reason that Typescript

If you want to convert .ts
files into .js
, do this as per your need
tsc file.ts // file.ts will be converted to file.js file
tsc // all .ts files will be converted to .js files in the directory
tsc --watch // converts all .ts files to .js, and watch changes in .ts files
Parameters are the variables received by a function.Hence they are visible in function declaration.They contain the variable name with their data type. Arguments are actual values which are passed to another function. thats why we can see them in function call. They are just values without their datatype
Use the Oracle 10g dialect. Also Hibernate 3.3.2+ is required for recent JDBC drivers (the internal class structure changed - symptoms will be whining about an abstract class).

I say use a DateTime. If you don't need the date portion, just ignore it. If you need to display just the time to the user, output it formatted to the user like this:
DateTime.Now.ToString("t"); // outputs 10:00 PM
It seems like all the extra work of making a new class or even using a TimeSpan is unnecessary.
int first = string.indexOf("is");
int second = string.indexOf("is", first + 1);
This overload starts looking for the substring from the given index.

Here's what I use:
NSString * timestamp = [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];
(times 1000 for milliseconds, otherwise, take that out)
If You're using it all the time, it might be nice to declare a macro
#define TimeStamp [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000]
Then Call it like this:
NSString * timestamp = TimeStamp;
Or as a method:
- (NSString *) timeStamp {
return [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];
}
As TimeInterval
- (NSTimeInterval) timeStamp {
return [[NSDate date] timeIntervalSince1970] * 1000;
}
NOTE:
The 1000 is to convert the timestamp to milliseconds. You can remove this if you prefer your timeInterval in seconds.
Swift
If you'd like a global variable in Swift, you could use this:
var Timestamp: String {
return "\(NSDate().timeIntervalSince1970 * 1000)"
}
Then, you can call it
println("Timestamp: \(Timestamp)")
Again, the *1000
is for miliseconds, if you'd prefer, you can remove that. If you want to keep it as an NSTimeInterval
var Timestamp: NSTimeInterval {
return NSDate().timeIntervalSince1970 * 1000
}
Declare these outside of the context of any class and they'll be accessible anywhere.

You'll want something like this:
$("#next").click(function(){
var currentElement = currentElement.next();
$('html, body').animate({scrollLeft: $(currentElement).offset().left}, 800);
return false;
});
I believe this should work, it's adopted from a scrollTop

Not even WURLF can.
As stated in the relevant RxJS documentation, the .subscribe()
method can take a third argument that is called on completion if there are no errors.
For reference:
[onNext]
(Function
): Function to invoke for each element in the observable sequence.[onError]
(Function
): Function to invoke upon exceptional termination of the observable sequence.[onCompleted]
(Function
): Function to invoke upon graceful termination of the observable sequence.
Therefore you can handle your routing logic in the onCompleted
callback since it will be called upon graceful termination (which implies that there won't be any errors when it is called).
this.httpService.makeRequest()
.subscribe(
result => {
// Handle result
console.log(result)
},
error => {
this.errors = error;
},
() => {
// 'onCompleted' callback.
// No errors, route to new page here
}
);
As a side note, there is also a .finally()
method which is called on completion regardless of the success/failure of the call. This may be helpful in scenarios where you always want to execute certain logic after an HTTP request regardless of the result (i.e., for logging purposes or for some UI interaction such as showing a modal).
Rx.Observable.prototype.finally(action)
Invokes a specified action after the source observable sequence terminates gracefully or exceptionally.
For instance, here is a basic example:
import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/finally';
// ...
this.httpService.getRequest()
.finally(() => {
// Execute after graceful or exceptionally termination
console.log('Handle logging logic...');
})
.subscribe (
result => {
// Handle result
console.log(result)
},
error => {
this.errors = error;
},
() => {
// No errors, route to new page
}
);
I wrote a full replacement for sys.stderr

To use this you can just call StdErrReplament::lock(logger)
and StdOutReplament::lock(logger)
passing the logger you want to use to send the output text. For example:
import os
import sys
import logging
current_folder = os.path.dirname( os.path.realpath( __file__ ) )
log_file_path = os.path.join( current_folder, "my_log_file.txt" )
file_handler = logging.FileHandler( log_file_path, 'a' )
file_handler.formatter = logging.Formatter( "%(asctime)s %(name)s %(levelname)s - %(message)s", "%Y-%m-%d %H:%M:%S" )
log = logging.getLogger( __name__ )
log.setLevel( "DEBUG" )
log.addHandler( file_handler )
log.file_handler = file_handler
log.clean_formatter = logging.Formatter( "", "" )
StdOutReplament.lock( log )
StdErrReplament.lock( log )
log.debug( "I am doing usual logging debug..." )
sys.stderr.write( "Tests 1...\n" )
sys.stdout.write( "Tests 2...\n" )
Running this code, you will see on the screen:
And on the file contents:
If you would like to also see the contents of the log.debug
calls on the screen, you will need to add a stream handler to your logger. On this case it would be like this:
import os
import sys
import logging
class ContextFilter(logging.Filter):
""" This filter avoids duplicated information to be displayed to the StreamHandler log. """
def filter(self, record):
return not "_duplicated_from_file" in record.__dict__
current_folder = os.path.dirname( os.path.realpath( __file__ ) )
log_file_path = os.path.join( current_folder, "my_log_file.txt" )
stream_handler = logging.StreamHandler()
file_handler = logging.FileHandler( log_file_path, 'a' )
formatter = logging.Formatter( "%(asctime)s %(name)s %(levelname)s - %(message)s", "%Y-%m-%d %H:%M:%S" )
file_handler.formatter = formatter
stream_handler.formatter = formatter
stream_handler.addFilter( ContextFilter() )
log = logging.getLogger( __name__ )
log.setLevel( "DEBUG" )
log.addHandler( file_handler )
log.addHandler( stream_handler )
log.file_handler = file_handler
log.stream_handler = stream_handler
log.clean_formatter = logging.Formatter( "", "" )
StdOutReplament.lock( log )
StdErrReplament.lock( log )
log.debug( "I am doing usual logging debug..." )
sys.stderr.write( "Tests 1...\n" )
sys.stdout.write( "Tests 2...\n" )
Which would output like this when running:
While it would still saving this to the file my_log_file.txt
:
When disabling this with StdErrReplament:unlock()
, it will only restore the standard behavior of the stderr
stream, as the attached logger cannot be never detached because someone else can have a reference to its older version. This is why it is a global singleton which can never dies. Therefore, in case of reloading this module with imp
or something else, it will never recapture the current sys.stderr
as it was already injected on it and have it saved internally.
I solved a similar case by setting the inner item's style to margin: 0 auto
.
Situation: My menu usually contains three buttons, in which case they need to be justify-content: space-between

This command printed the following error:
TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
So, I performed the following actions:
listener.ora
or sqlnet.ora
file contains special characterslistener.ora
or sqlnet.ora` file are in wrong format or syntaxlistener.ora
or sqlnet.ora
file have some left justified parenthesis which are not accepted by oracle parser.Have a look at these files and check the proper syntax. If possible remove/rename sqlnet.ora and try to restart the listener. Or remove/rename both listener.ora or sqlnet.ora file and recreate it properly. These will defenitely resolve the issue.

The Unlocker site has a nifty chart (scroll down after following the link) that shows a comparison to other tools. Obviously such comparisons are usually biased since they are typically written by the tool author, but the chart at least lists the alternatives so that you can try them for yourself.

The middle one writes to the pipeline. Write-Host
and Out-Host
writes to the console. 'echo' is an alias for Write-Output
which writes to the pipeline as well. The best way to write to the console would be using the Write-Host
cmdlet.
When an object is written to the pipeline it can be consumed by other commands in the chain. For example:
"hello world" | Do-Something
but this won't work since Write-Host
writes to the console, not to the pipeline (Do-Something will not get the string):
Write-Host "hello world" | Do-Something
You can use the instanceof
operator for this. From MDN:
The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.
If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:
class Animal {_x000D_
name;_x000D_
_x000D_
constructor(name) {_x000D_
this.name = name;_x000D_
}_x000D_
}_x000D_
_x000D_
const animal = new Animal('fluffy');_x000D_
_x000D_
// true because Animal in on the prototype chain of animal_x000D_
console.log(animal instanceof Animal); // true_x000D_
// Proof that Animal is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
_x000D_
// true because Object in on the prototype chain of animal_x000D_
console.log(animal instanceof Object); _x000D_
// Proof that Object is on the prototype chain_x000D_
console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
_x000D_
console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
_x000D_
_x000D_
The prototype chain in this example is:
animal > Animal.prototype > Object.prototype

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.
You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.
Here is my solution:
<div class="form-group row">
<div class="col-xs-8">
<label class="control-label">My Label</label>
<div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
<input class="form-control" type="text" readonly="" value="12-02-2012">
<span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</div>
</div>
CSS changes in datepicker.css on lines 176-177:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 34:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;
UPDATE
Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:
CSS changes in datepicker.css on lines 446-447:
.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {
Javascript change in datepicker-bootstrap.js on line 46:
this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;
Finally, the JavaScript to enable the datepicker (with some options):
$(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });
Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.
window.location.href=window.location.href;
Just for fun (I had some time to kill), a more sophisticated implementation which caches the zero-string:
pad.zeros = new Array(5).join('0');
function pad(num, len) {
var str = String(num),
diff = len - str.length;
if(diff <= 0) return str;
if(diff > pad.zeros.length)
pad.zeros = new Array(diff + 1).join('0');
return pad.zeros.substr(0, diff) + str;
}
If the padding count is large and the function is called often enough, it actually outperforms the other methods...
As of June 2009 the originally cited blog post has a method to create animated GIFs in the comments. Download the script images2gif.py (formerly images2gif.py, update courtesy of @geographika).
Then, to reverse the frames in a gif, for instance:
#!/usr/bin/env python
from PIL import Image, ImageSequence
import sys, os
filename = sys.argv[1]
im = Image.open(filename)
original_duration = im.info['duration']
frames = [frame.copy() for frame in ImageSequence.Iterator(im)]
frames.reverse()
from images2gif import writeGif
writeGif("reverse_" + os.path.basename(filename), frames, duration=original_duration/1000.0, dither=0)
Here's an approach using generators:
function* square(n) {
for (var i = 0; i < n; i++ ) yield i*i;
}
Then you can write
console.log(...square(7));
Another idea is:
[...Array(5)].map((_, i) => i*i)
Array(5)
creates an unfilled five-element array. That's how Array
works when given a single argument. We use the spread operator to create an array with five undefined elements. That we can then map. See http://ariya.ofilabs.com/2013/07/sequences-using-javascript-array.html.
Alternatively, we could write
Array.from(Array(5)).map((_, i) => i*i)
or, we could take advantage of the second argument to Array#from
to skip the map
and write
Array.from(Array(5), (_, i) => i*i)
A horrible hack which I saw recently, which I do not recommend you use, is
[...1e4+''].map((_, i) => i*i)
To download a file please use the following code ... Store the File name with location in $file variable. It supports all mime type
$file = "location of file to download"
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
To know about Mime types please refer to this link: http://php.net/manual/en/function.mime-content-type.php
You should use the string replace function, with a single regex. Assuming by special characters, you mean anything that's not letter, here is a solution:
const str = "abc's test#s";_x000D_
console.log(str.replace(/[^a-zA-Z ]/g, ""));
_x000D_
As Peter and Amro illustrate, you have to convert numeric values to formatted strings first in order to display them or concatenate them with other character strings. You can do this using the functions FPRINTF, SPRINTF, NUM2STR, and INT2STR.
With respect to getting ans = 3
as an output, it is probably because you are not assigning the output from answer
to a variable. If you want to get all of the output values, you will have to call answer
in the following way:
[out1,out2,out3] = answer(1,2);
This will place the value d
in out1
, the value e
in out2
, and the value f
in out3
. When you do the following:
answer(1,2)
MATLAB will automatically assign the first output d
(which has the value 3 in this case) to the default workspace variable ans
.
With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. I've learned most of what I know on my own using it. You can access it online, or within your copy of MATLAB using the functions DOC, HELP, or HELPWIN.
It's caused by n % x
, when x
is 0. You should have x start at 2 instead. You should not use floating point here at all, since you only need integer operations.
General notes:
q
to be global.$timeFirst = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;
You will then be able to use the seconds to find minutes, hours, days, etc.
I've run into cases where __file__
doesn't work as expected. But the following hasn't failed me so far:
import inspect
src_file_path = inspect.getfile(lambda: None)
This is the closest thing to a Python analog to C's __FILE__
.
The behavior of Python's __file__
is much different than C's __FILE__
. The C version will give you the original path of the source file. This is useful in logging errors and knowing which source file has the bug.
Python's __file__
only gives you the name of the currently executing file, which may not be very useful in log output.
I think you need to have strings as the data values. It's likely something internally within jQuery that isn't encoding/serializing correctly the To & From Objects.
Try:
var data = {
from : from.val(),
to : to.val(),
speed : speed
};
Notice also on the lines:
$(from).css(...
$(to).css(
You don't need the jQuery wrapper as To & From are already jQuery objects.
You can add anchor tags. I use this on my site so that I can track with Google Analytics what people are visiting on the page.
I just add an anchor tag and then the part of the page I want to track:
var trackCode = "/#" + urlencode($("myDiv").text());
window.location.href = "http://www.piano-chords.net" + trackCode;
pageTracker._trackPageview(trackCode);

Sebastian Godelet mentions in the comments:
In C:

As commented, you can also call the WinAPI, but... as shown in "How to obtain data from WMI using a C Application?", this is quite complex (and generally done with C++, not C).
Or with PowerShell:
Get-WmiObject Win32_DiskDrive
Probably invalid syntax in your onChange event, I avoid using like this (within the html) as I think it is messy and it is hard enough keeping JavaScript tidy at the best of times.
I would rather register the event on the document ready event in javascript. You will also definitely want to use keyup event too if you want the validation as the user is typing:
$(document).ready(function () {
$("#txtConfirmPassword").keyup(checkPasswordMatch);
});
Personally I would prefer to do the check when either password field changes, that way if they re-type the original password then you still get the same validation check:
$(document).ready(function () {
$("#txtNewPassword, #txtConfirmPassword").keyup(checkPasswordMatch);
});
Bootstrap provide us with .disabled
class. Please use it.
But .disabled
class only works when the 'a' tag already has class 'btn'. It doesn' t work on any old 'a' tag. The btn
class may not be appropriate in some context as it has style connotations. Under the covers, the .disabled
class sets pointer-events
to none
, so you can make CSS to do the same thing as Saroj Aryal and Vitrilo have sugested. (Thank you, Les Nightingill for this advice).
If one uses the tool Linqpad, after one connects to a target database from the connections one can get a connection string to use.

I had the same scenario in my job and here are our findings
The first thing you have to do is get the certificate and install it on your computer, you can either buy one from a Certificate Authority or generate one using makecert.
Here are the pros and cons of the 2 options
Buy a certificate
There is a cost involved on getting a certificate from a CA
For prices, see https://cheapsslsecurity.com/sslproducts/codesigningcertificate.html and https://www.digicert.com/code-signing/
Generate a certificate using Makecert
Sign the executable file
There are two ways of signing the file you want:
Using a certificate installed on the computer
signtool.exe sign /a /s MY /sha1 sha1_thumbprint_value /t http://timestamp.verisign.com/scripts/timstamp.dll /v "C:\filename.dll"
C:\filename.dll
Using a certificate file
signtool sign /tr http://timestamp.digicert.com /td sha256 /fd sha256 /f "c:\path\to\mycert.pfx" /p pfxpassword "c:\path\to\file.exe"
c:\path\to\mycert.pfx
with the password pfxpassword
to sign the file c:\path\to\file.exe
Test Your Signature
Method 1: Using signtool
Go to: Start > Run
Type CMD
> click OK
At the command prompt, enter the directory where signtool
exists
Run the following:
signtool.exe verify /pa /v "C:\filename.dll"
Method 2: Using Windows
Right-click the signed file
Select Properties
Select the Digital Signatures tab. The signature will be displayed in the Signature list section.
I hope this could help you

Mongodb v3.4
You need to do the following to create a secure database:
Make sure the user starting the process has permissions and that the directories exist (/data/db
in this case).
1) Start MongoDB without access control.
mongod --port 27017 --dbpath /data/db
2) Connect to the instance.
mongo --port 27017
3) Create the user administrator (in the admin authentication database).
use admin
db.createUser(
{
user: "myUserAdmin",
pwd: "abc123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
4) Re-start the MongoDB instance with access control.
mongod --auth --port 27017 --dbpath /data/db
5) Connect and authenticate as the user administrator.
mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
6) Create additional users as needed for your deployment (e.g. in the test authentication database).
use test
db.createUser(
{
user: "myTester",
pwd: "xyz123",
roles: [ { role: "readWrite", db: "test" },
{ role: "read", db: "reporting" } ]
}
)
7) Connect and authenticate as myTester.
mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"

Why the Hell Would You Use Node.js
https://medium.com/the-node-js-collection/why-the-hell-would-you-use-node-js-4b053b94ab8e
Where Node.js really shines is in building fast, scalable network applications, as it’s capable of handling a huge number of simultaneous connections with high throughput, which equates to high scalability. How it works under-the-hood is pretty interesting. Compared to traditional web-serving techniques where each connection (request) spawns a new thread, taking up system RAM and eventually maxing-out at the amount of RAM available, Node.js operates on a single-thread, using non-blocking I/O calls, allowing it to support tens of thousands of concurrent connections (held in the event loop).
Simply replace the whole thing with:
return File.ReadAllBytes(fileName);
However, if you are concerned about the memory consumption, you should not read the whole file into memory all at once at all. You should do that in chunks.
Here is how I wrote it using jQuery. Tested in Firefox and Internet Explorer.
function postToUrl(url, params, newWindow) {
var form = $('<form>');
form.attr('action', url);
form.attr('method', 'POST');
if(newWindow){ form.attr('target', '_blank');
}
var addParam = function(paramName, paramValue) {

Your model is @Messages
, change it to @message
.
To change it like you should use migration:
def change rename_table :old_table_name, :new_table_name end
Of course do not create that file by hand but use rails generator:
rails g migration ChangeMessagesToMessage
That will generate new file with proper timestamp in name in 'db
dir. Then run:
rake db:migrate
And your app should be fine since then.
To backup a single database from the command line, use osql or sqlcmd.
"C:\Program Files\Microsoft SQL Server\90\Tools\Binn\osql.exe"
-E -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak' WITH FORMAT"
You'll also want to read the documentation on BACKUP and RESTORE and general procedures.
If the goal is to randomly shuffle each column, some of the above answers don't work since the columns are shuffled jointly (this preserves inter-column correlations). Others require installing a package. Yet a one-liner exist:
df2 = lapply(df1, function(x) { sample(x) })
Use git reset:
git reset --hard "Version 1.0 Revision 1.5"
(assuming that the specified string is the tag).
I suggest to use DateTime and DateInterval objects.
$date1 = new DateTime("2007-03-24");
$date2 = new DateTime("2009-06-26");
$interval = $date1->diff($date2);
echo "difference " . $interval->y . " years, " . $interval->m." months, ".$interval->d." days ";
// shows the total amount of days (not divided into years, months and days like above)
echo "difference " . $interval->days . " days ";
read more php DateTime::diff manual
From the manual:
As of PHP 5.2.2, DateTime objects can be compared using comparison operators.
$date1 = new DateTime("now");
$date2 = new DateTime("tomorrow");
var_dump($date1 == $date2); // bool(false)
var_dump($date1 < $date2); // bool(true)
var_dump($date1 > $date2); // bool(false)
I believe the previous answer is the correct answer to this problem but I was getting this error when I tried installing npm package (see below) :
The fix for me was : npm init --yes
put x=0 outside the for loop that is the problem
In case that you're interested in specific lines, use a result-array:
declare RESULT=($(./myscript)) # (..) = array
echo "First line: ${RESULT[0]}"
echo "Second line: ${RESULT[1]}"
echo "N-th line: ${RESULT[N]}"
Using PreparedStatements will be MUCH slower than Statements if you have low iterations. To gain a performance benefit from using a PrepareStatement over a statement, you need to be using it in a loop where iterations are at least 50 or higher.
you should do import Map from './Map'
React is just telling you it doesn't know where variable you are importing is.
You can use awk
with a system
call readlink
to get the equivalent of an ls
output with full symlink paths. For example:
ls | awk '{printf("%s ->", $1); system("readlink -f " $1)}'

Here is a solution to get the country based on an international phone number without using the Google library.
Let me explain first why it is so difficult to figure out the country. The country code of few countries is 1 digit, 2, 3 or 4 digits. That would be simple enough. But the country code 1 is not just used for US, but also for Canada and some smaller places:
1339 USA
1340 Virgin Islands (Caribbean Islands)
1341 USA
1342 not used
1343 Canada
Digits 2..4 decide, if it is US or Canada or ... There is no easy way to figure out the country, like the first xxx are Canada, the rest US.
For my code, I defined a class which holds information for ever digit:
public class DigitInfo {
public char Digit;
public Country? Country;
public DigitInfo?[]? Digits;
}
A first array holds the DigitInfos for the first digit in the number. The second digit is used as an index into DigitInfo.Digits. One travels down that Digits chain, until Digits is empty. If Country is defined (i.e. not null) that value gets returned, otherwise any Country defined earlier gets returned:
country code 1: byPhone[1].Country is US
country code 1236: byPhone[1].Digits[2].Digits[3].Digits[6].Country is Canada
country code 1235: byPhone[1].Digits[2].Digits[3].Digits[5].Country is null. Since
byPhone[1].Country is US, also 1235 is US, because no other
country was found in the later digits
Here is the method which returns the country based on the phone number:
/// <summary>
/// Returns the Country based on an international dialing code.
/// </summary>
public static Country? GetCountry(ReadOnlySpan<char> phoneNumber) {
if (phoneNumber.Length==0) return null;
var isFirstDigit = true;
DigitInfo? digitInfo = null;
Country? country = null;
foreach (var digitChar in phoneNumber) {
var digitIndex = digitChar - '0';
if (isFirstDigit) {
isFirstDigit = false;
digitInfo = ByPhone[digitIndex];
} else {
if (digitInfo!.Digits is null) return country;
digitInfo = digitInfo.Digits[digitIndex];
}
if (digitInfo is null) return country;
country = digitInfo.Country??country;
}
return country;
}
The rest of the code (digitInfos for every country of the world, test code, ...) is too big to be posted here, but it can be found on Github: https://github.com/PeterHuberSg/WpfWindowsLib/blob/master/WpfWindowsLib/CountryCode.cs
The code is part of a WPF TextBox and the library contains also other controls for email addresses, etc. A more detailed description is on CodeProject: International Phone Number Validation Explained in Detail
Things that are done at compile time incur (almost) no cost when the resulting program is run, but might incur a large cost when you build the program.
More or less the exact opposite. Little cost when you build, more cost when the program is run.
From the other side; If something is done at compile time, it runs only on your machine and if something is run-time, it run on your users machine.
An example of where this is important would be a unit carrying type. A compile time version (like Boost.Units or my version in D) ends up being just as fast as solving the problem with native floating point code while a run-time version ends up having to pack around information about the units that a value are in and perform checks in them along side every operation. On the other hand, the compile time versions requiter that the units of the values be known at compile time and can't deal with the case where they come from run-time input.
To append a string, just concatenate it with the +
sign.
E.g.
>>> a = "Hello, "
>>> b = "world"
>>> str = a + b
>>> print str
Hello, world
join
connects strings together with a separator. The separator is what you
place right before the join
. E.g.
>>> "-".join([a,b])
'Hello, -world'
Join takes a list of strings as a parameter.
Let's say there is an administrator dashboard where users are listed with their id printed as a data attribute so it can be retrieved at some point via JavaScript.
An update could be executed this way …
class UserRepository extends \Doctrine\ORM\EntityRepository
{
public function updateUserStatus($userId, $newStatus)
{
return $this->createQueryBuilder('u')
->update()
->set('u.isActive', '?1')
->setParameter(1, $qb->expr()->literal($newStatus))
->where('u.id = ?2')
->setParameter(2, $qb->expr()->literal($userId))
->getQuery()
->getSingleScalarResult()
;
}
AJAX action handling:
# Post datas may be:
# handled with a specific custom formType — OR — retrieved from request object
$userId = (int)$request->request->get('userId');
$newStatus = (int)$request->request->get('newStatus');
$em = $this->getDoctrine()->getManager();
$r = $em->getRepository('NAMESPACE\User')
->updateUserStatus($userId, $newStatus);
if ( !empty($r) ){
# Row updated
}
Working example using Doctrine 2.5 (on top of Symfony3).
To close your current window using JS, do this. First open the current window to trick your current tab into thinking it has been opened by a script. Then close it using window.close(). The below script should go into the parent window, not the child window. You could run this after running the script to open the child.
<script type="text/javascript">
window.open('','_parent','');
window.close();
</script>

I too got this error. Incidentally, i typed __int__ instead of __init__.
I think, in many mistype cases the IDE i am using (IntelliJ) would have changed the color to the default set for Function definition. But, in my case __int__ being another dunder/magic method, color remained same as the one which IDE displays for __init__ (default Predefined item definition color), which took me some time in spotting the missing i.
int count = Regex.Matches(myString,"$").Count;
Two ways are there by which you can use to erase an item particularly. lets take a vector
std :: vector < int > v;
v.push_back(10);
v.push_back(20);
v.push_back(30);
v.push_back(40);
v.push_back(40);
v.push_back(50);
1) Non efficient way : Although it seems to be quite efficient but it's not because erase function delets the elements and shifts all the elements towards left by 1. so its complexity will be O(n^2)
std :: vector < int > :: iterator itr = v.begin();
int value = 40;
while ( itr != v.end() )
{
if(*itr == value)
{
v.erase(itr);
}
else
++itr;
}
2) Efficient way ( RECOMMENDED ) : It is also known as ERASE - REMOVE idioms .
output of the remove algorithm is :
10 20 30 50 40 50
as return type of remove is iterator to the new end of that range.
template <class ForwardIterator, class T>
ForwardIterator remove (ForwardIterator first, ForwardIterator last, const T& val);
Now use vector’s erase function to delete elements from the new end to old end of the vector. It requires O(1) time.
v.erase ( std :: remove (v.begin() , v.end() , element ) , v.end () );
so this method work in O(n)
fill
all items with undefined
before using map
:?? Array.fill
has no IE support
// run 5 times:
Array(5).fill().map((item, i)=>{
console.log(i) // print index
})
_x000D_
There is nice "trick" using destructuring Array, replacing fill
with:
Array(5).fill()
? [...Array(5)]
which does the same, filling the array with undefined
.
If you want to make the above more "declarative", my currently opinion-based solution would be:
const iterate = times => callback => [...Array(times)].map((n,i) => callback(i))
iterate(3)(console.log)
_x000D_
// run 5 times:
for( let i=5; i--; )
console.log(i)
_x000D_
Or as a declarative "while":
const times = count => callback => { while(count--) callback(count) }
times(3)(console.log)
_x000D_
The key is to select the target of your emulator to, for example: Google APIs (ver 18). If you select, for example, just Jellybean 18 (without API) you will not be able to test apps that require Google services such as map. Keep in mind that you must first download the Google API of your favorite version with the Android SDK Manager.
This is a good practice and it is far better than juggling with most workarounds.
I develop a good solution, I know there is much If
statements, but It works! (Its only for <1 numbers)
def truncate(number, digits) -> float:
startCounting = False
if number < 1:
number_str = str('{:.20f}'.format(number))
resp = ''
count_digits = 0
for i in range(0, len(number_str)):
if number_str[i] != '0' and number_str[i] != '.' and number_str[i] != ',':
startCounting = True
if startCounting:
count_digits = count_digits + 1
resp = resp + number_str[i]
if count_digits == digits:
break
return resp
else:
return number
Use navigator.clipboard.writeText
to copy the content to clipboard
navigator.clipboard.writeText(content).then().catch(e => console.error(e));
When we code empty in essence could mean any one of the following given the circumstances;
In real life situation as OP stated we may wish to test them all or at times we may only wish to test for limited set of conditions.
Generally if(!a){return true;}
serves its purpose most of the time however it will not cover wider set of conditions.
Another hack that has made its round is return (!value || value == undefined || value == "" || value.length == 0);
But what if we need control on whole process?
There is no simple whiplash solution in native core JavaScript it has to be adopted. Considering we drop support for legacy IE11 (to be honest even windows has so should we) below solution born out of frustration works in all modern browsers;
function empty (a,b=[])
{if(!Array.isArray(b)) return;
var conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(conditions.includes(a)|| (typeof a === 'string' && conditions.includes(a.toString().trim())))
{return true;};
return false;};`
Logic behind the solution is function has two parameters a and b, a is value we need to check, b is a array with set conditions we need to exclude from predefined conditions as listed above. Default value of b is set to an empty array [].
First run of function is to check if b is an array or not, if not then early exit the function.
next step is to compute array difference from [null,'0','0.0',false,undefined,'']
and from array b. if b is an empty array predefined conditions will stand else it will remove matching values.
conditions = [predefined set] - [to be excluded set] filter function does exactly that make use of it. Now that we have conditions in array set all we need to do is check if value is in conditions array. includes function does exactly that no need to write nasty loops of your own let JS engine do the heavy lifting.
Gotcha if we are to convert a into string for comparison then 0 and 0.0 would run fine however Null and Undefined would through error blocking whole script. We need edge case solution. Below simple || covers the edge case if first condition is not satisfied. Running another early check through include makes early exit if not met.
if(conditions.includes(a)|| (['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim())))
trim() function will cover for wider white spaces and tabs only value and will only come into play in edge case scenario.
Play ground
function empty (a,b=[]){
if(!Array.isArray(b)) return;
conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(conditions.includes(a)||
(['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim()))){
return true;
}
return false;
}
console.log('1 '+empty());
console.log('2 '+empty(''));
console.log('3 '+empty(' '));
console.log('4 '+empty(0));
console.log('5 '+empty('0'));
console.log('6 '+empty(0.0));
console.log('7 '+empty('0.0'));
console.log('8 '+empty(false));
console.log('9 '+empty(null));
console.log('10 '+empty(null,[null]));
console.log('11 dont check 0 as number '+empty(0,['0']));
console.log('12 dont check 0 as string '+empty('0',['0']));
console.log('13 as number for false as value'+empty(false,[false]));
_x000D_
Lets make it complex - what if our value to compare is array its self and can be as deeply nested it can be. what if we are to check if any value in array is empty, it can be an edge business case.
function empty (a,b=[]){
if(!Array.isArray(b)) return;
conditions=[null,'0','0.0',false,undefined,''].filter(x => !b.includes(x));
if(Array.isArray(a) && a.length > 0){
for (i = 0; i < a.length; i++) { if (empty(a[i],b))return true;}
}
if(conditions.includes(a)||
(['string', 'number'].includes(typeof a) && conditions.includes(a.toString().trim()))){
return true;
}
return false;
}
console.log('checking for all values '+empty([1,[0]]));
console.log('excluding for 0 from condition '+empty([1,[0]], ['0']));
_x000D_
it simple and wider use case function that I have adopted in my framework;
try this one:-

EventArgs e
is a parameter called e that contains the event data, see the EventArgs MSDN page for more information.
Object Sender
is a parameter called Sender that contains a reference to the control/object that raised the event.

Edit: When Button is clicked, the btn_Click event handler will be fired. The "object sender" portion will be a reference to the button which was clicked
Make sure that you are installing the Anaconda binary that is compatible with your kernel. I was in the same situation.Turned out I have an x64_86 CPU and was trying to install a 64 bit Power 8 installer.You can find out the same for your CPU by using the following command.It gives you a basic information about a computer's software and hardware.-

First of all: there is nothing like JUnit XML Format Specification
, simply because JUnit doesn't produce any kind of XML or HTML report.
The XML report generation itself comes from the Ant JUnit task/ Maven Surefire Plugin/ Gradle (whichever you use for running your tests). The XML report format was first introduced by Ant and later adapted by Maven (and Gradle).

If your <option>
elements don't have value
attributes, then you can just use .val
:
$selectElement.val("text_you're_looking_for")
However, if your <option>
elements have value attributes, or might do in future, then this won't work, because whenever possible .val
will select an option by its value
attribute instead of by its text content. There's no built-in jQuery method that will select an option by its text content if the options have value
attributes, so we'll have to add one ourselves with a simple plugin:
/*
Source: https://stackoverflow.com/a/16887276/1709587
Usage instructions:
Call
jQuery('#mySelectElement').selectOptionWithText('target_text');
to select the <option> element from within #mySelectElement whose text content
is 'target_text' (or do nothing if no such <option> element exists).
*/
jQuery.fn.selectOptionWithText = function selectOptionWithText(targetText) {
return this.each(function () {
var $selectElement, $options, $targetOption;
$selectElement = jQuery(this);
$options = $selectElement.find('option');
$targetOption = $options.filter(
function () {return jQuery(this).text() == targetText}
);
// We use `.prop` if it's available (which it should be for any jQuery
// versions above and including 1.6), and fall back on `.attr` (which
// was used for changing DOM properties in pre-1.6) otherwise.
if ($targetOption.prop) {
$targetOption.prop('selected', true);
}
else {
$targetOption.attr('selected', 'true');
}
});
}
Just include this plugin somewhere after you add jQuery onto the page, and then do
jQuery('#someSelectElement').selectOptionWithText('Some Target Text');
to select options.
The plugin method uses filter
to pick out only the option
matching the targetText, and selects it using either .attr
or .prop
, depending upon jQuery version (see .prop() vs .attr() for explanation).
Here's a JSFiddle you can use to play with all three answers given to this question, which demonstrates that this one is the only one to reliably work: http://jsfiddle.net/3cLm5/1/
The "up" affordance indicator is provided by a drawable specified in the homeAsUpIndicator

</style>
If you are supporting pre-3.0 with your application be sure you put this version of the custom theme in values-v11
or similar.

For me the easiest solution was to import swagger (v2) into Postman and then go to the web view. There you can choose "single column" view and use the browser to print to pdf. Not a automated/integrated solution but good for single-use. It handles paper-width much better than printing from editor2.swagger.io, where scrollbars cause portions of the content to be hidden.
iconv -f FROM-ENCODING -t TO-ENCODING file.txt
Also there are iconv-based tools in many languages.
$(window).scroll(function() {
$('.logo_container, .slogan').css({
"opacity" : ".1",
"transition" : "opacity .8s ease-in-out"
});
});

The angular documentation for select* does not answer this question explicitly, but it is there. If you look at the script.js
, you will see this:
function MyCntrl($scope) {
$scope.colors = [
{name:'black', shade:'dark'},
{name:'white', shade:'light'},
{name:'red', shade:'dark'},
{name:'blue', shade:'dark'},
{name:'yellow', shade:'light'}
];
$scope.color = $scope.colors[2]; // Default the color to red
}
This is the html:
<select ng-model="color" ng-options="c.name for c in colors"></select>
This seems to be a more obvious way of defaulting a selected value on an <select>
with ng-options
. Also it will work if you have different label/values.

Based on answer by @Cici I give here a more generic solution:
=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))
In Italian version of Excel:
=SOMMA(INDIRETTO(CONCATENA(B1;C1)):INDIRETTO(CONCATENA(B2;C2)))
Where B1-C2 cells hold these values:
You can change these valuese to change the final range at wish.
Splitting the formula in parts:
Hence:
=SUM(INDIRECT(CONCATENATE(B1,C1)):INDIRECT(CONCATENATE(B2,C2)))
results in
=SUM(A1:A5)
I'll write down here a couple of SEO keywords for Italian users:
Con la formula indicata qui sopra basta scrivere nelle caselle da B1 a C2 gli estremi dell'intervallo per vedelo cambiare dentro la formula stessa.
It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.
@Request/View/Flow/Session/ApplicationScoped
A @RequestScoped
bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped
bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null
/void
without any navigation/redirect. A @FlowScoped
bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped
bean lives as long as the established HTTP session. An @ApplicationScoped
bean lives as long as the web application runs. Note that the CDI @Model
is basically a stereotype for @Named @RequestScoped
, so same rules apply.
Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped
for simple and non-ajax forms/presentations. Use @ViewScoped
for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped
for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped
for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped
for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.
Abusing an @ApplicationScoped
bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped
bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped
bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped
bean for request, session or application scoped data, and abusing a @SessionScoped
bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.
Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped
beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty
in case of JSF managed beans or @Inject
in case of CDI managed beans.
@CustomScoped/NoneScoped/Dependent
It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped
and @NoneScoped
, which are rarely used in real world. The @CustomScoped
must refer a custom Map<K, Bean>
implementation in some broader scope which has overridden Map#put()
and/or Map#get()
in order to have more fine grained control over bean creation and/or destroy.
The JSF @NoneScoped
and CDI @Dependent
basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped
or @Dependent
is injected in a @SessionScoped
, then it will live as long as the @SessionScoped
bean.
As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.
This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped
. The flash scope is only available as a map via ExternalContext#getFlash()
in managed beans and #{flash}
in EL.

You cannot style a variable such as $ip['countryName']
You can only style elements like p,div, etc, or classes and ids.
If you want to style $ip['countryName'] there are several ways.
You can echo it within an element:
echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';
If you want to style both the variables the same style, then set a class like:
echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';
You could also embed the variables within your actual html rather than echoing them out within the code.
$city = $ip['cityName'];
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>
Use the attribute 'display' as in the example:
<span style="background: gray; width: 100px; display:block;">hello</span>
<span style="background: gray; width: 200px; display:block;">world</span>
I've already posted
GetItemValue
extension method in this post Get the value for a listbox item by index. This extension method will work for allListControl
classes includingCheckedListBox
,ListBox
andComboBox
.
None of the existing answers are general enough, but there is a general solution for the problem.
In all cases, the underlying Value
of an item should be calculated regarding to ValueMember
, regardless of the type of data source.
The data source of the CheckedListBox
may be a DataTable
or it may be a list which contains objects, like a List<T>
, so the items of a CheckedListBox
control may be DataRowView
, Complex Objects, Anonymous types, primary types and other types.
GetItemValue Extension Method
We need a GetItemValue
which works similar to GetItemText
, but return an object, the underlying value of an item, regardless of the type of object you added as item.
We can create GetItemValue
extension method to get item value which works like GetItemText
:
using System;
using System.Windows.Forms;
using System.ComponentModel;
public static class ListControlExtensions
{
public static object GetItemValue(this ListControl list, object item)
{
if (item == null)
throw new ArgumentNullException("item");
if (string.IsNullOrEmpty(list.ValueMember))
return item;
var property = TypeDescriptor.GetProperties(item)[list.ValueMember];
if (property == null)
throw new ArgumentException(
string.Format("item doesn't contain '{0}' property or column.",
list.ValueMember));
return property.GetValue(item);
}
}
Using above method you don't need to worry about settings of ListBox
and it will return expected Value
for an item. It works with List<T>
, Array
, ArrayList
, DataTable
, List of Anonymous Types, list of primary types and all other lists which you can use as data source. Here is an example of usage:
//Gets underlying value at index 2 based on settings
this.checkedListBox.GetItemValue(this.checkedListBox.Items[2]);
Since we created the GetItemValue
method as an extension method, when you want to use the method, don't forget to include the namespace in which you put the class.
This method is applicable on ComboBox
and CheckedListBox
too.
Set flag -ObjC in Other linker Flag in your Project setting... (Not in the static library project but the project you that is using static library...) And make sure that in Project setting Configuration is set to All Configuration
Like edg indicated, you'll need a more complex algorithm to handle special names (this is probably why many places force everything to upper case).
Something like this untested c# should handle the simple case you requested:
public string SentenceCase(string input)
{
return input(0, 1).ToUpper + input.Substring(1).ToLower;
}
I just ran over this one and I found by accident that CLOBs can be used in a like query:
UPDATE IMS_TEST
SET TEST_Category = 'just testing'
WHERE TEST_SCRIPT LIKE '%something%'
AND ID = '10000239'
This worked also for CLOBs greater than 4K
The Performance won't be great but that was no problem in my case.
You are using Python 2 for which the input()
function tries to evaluate the expression entered. Because you enter a string, Python treats it as a name and tries to evaluate it. If there is no variable defined with that name you will get a NameError
exception.
To fix the problem, in Python 2, you can use raw_input()
. This returns the string entered by the user and does not attempt to evaluate it.
Note that if you were using Python 3, input()
behaves the same as raw_input()
does in Python 2.
Uncommenting the following line in host file worked for me,
#127.0.0.1 localhost
Tried the options above on Ubuntu 14.04, but they would constantly produce this error:
npm ERR! tar pack Error reading /root/tmp/npm-15864/1465947804069-0.4854120113886893/package
Then found this solution online:
1) Clean the cache of npm first:
sudo npm cache clean -f
2) Install n module of npm:
sudo npm install -g n
3) Begin the installation by selecting the version of node to install: stable or latest, we will use stable here:
sudo n stable
4) Check the version of node:
node -v
5) Check the version of npm:
npm -v
Related, so I thought I would post for others. If you want to find the UTC of the start of today (for your timezone) the following code works for any UTC offset (-23.5 thru +23.5). This looks like we add X hours then subtract X hours, but the important thing is the ".Date" after the add.
double utcOffset= 10.0; // Set to your UTC offset in hours (eg. Melbourne Australia)
var now = DateTime.UtcNow;
var startOfToday = now.AddHours(utcOffset - 24.0).Date;
startOfToday = startOfToday.AddHours(24.0 - utcOffset);
Considering the case that windows users prefer working on CRLF
and linux/mac users prefer working on LF
on text files. Providing the answer from the perspective of a repository maintainer:
For me the best strategy(less problems to solve) is: keep all text files with LF
inside git repo even if you are working on a windows-only project. Then give the freedom to clients to work on the line-ending style of their preference, provided that they pick a core.autocrlf
property value that will respect your strategy (LF on repo) while staging files for commit.
Staging is what many people confuse when trying to understand how newline strategies work. It is essential to undestand the following points before picking the correct value for core.autocrlf
property:
.git/
sub-directory with converted line-endings (depending on core.autocrlf
value on your client config). All this is done locally. core.autocrlf
is like providing an answer to the question (exact same question on all OS):
false:
"do none of the above", input:
"do only b"true
: "do a and and b"Fortunately
core.autocrlf: true
, linux/mac:
core.autocrlf: false
) will be compatible with LF-only-repo strategy.Unfortunately:
core.autocrlf
valuecore.autocrlf=false
and add a file with CRLF for commit.To detect ASAP non-lf text files committed by the above clients you can follow what is described on --- update 2 ---: (git grep -I --files-with-matches --perl-regexp '\r' HEAD
, on a client compiled using: --with-libpcre
flag)
And here is the catch:. I as a repo maintainer keep a git.autocrlf=input
so that I can fix any wrongly committed files just by adding them again for commit. And I provide a commit text: "Fixing wrongly committed files".
As far as .gitattributes
is concearned. I do not count on it, because there are more ui clients that do not understand it. I only use it to provide hints for text and binary files, and maybe flag some exceptional files that should everywhere keep the same line-endings:
*.java text !eol # Don't do auto-detection. Treat as text (don't set any eol rule. use client's)
*.jpg -text # Don't do auto-detection. Treat as binary
*.sh text eol=lf # Don't do auto-detection. Treat as text. Checkout and add with eol=lf
*.bat text eol=crlf # Treat as text. Checkout and add with eol=crlf
Answer: To avoid a single letter change commit, appear as a 5000-line change, just because the client that performed the change auto-converted the full file from crlf to lf (or the opposite) before adding it for commit. This can be rather painful when there is a conflict resolution involved. Or it could in some cases be the cause of unreasonable conflicts.
The dafaults of git client will work in most cases. Even if you only have windows only clients, linux only clients or both. These are:
core.autocrlf=true
means convert lines to CRLF on checkout and convert lines to LF when adding files.core.autocrlf=input
means don't convert lines on checkout (no need to since files are expected to be committed with LF) and convert lines to LF (if needed) when adding files.
(-- update3 -- : Seems that this is false
by default, but again it is fine)The property can be set in different scopes. I would suggest explicitly setting in the --global
scope, to avoid some IDE issues described at the end.
git config core.autocrlf
git config --global core.autocrlf
git config --system core.autocrlf
git config --local core.autocrlf
git config --show-origin core.autocrlf
Also I would strongly discourage using on windows git config --global core.autocrlf false
(in case you have windows only clients) in contrast to what is proposed to git documentation. Setting to false will commit files with CRLF in the repo. But there is really no reason. You never know whether you will need to share the project with linux users. Plus it's one extra step for each client that joins the project instead of using defaults.
Now for some special cases of files (e.g. *.bat
*.sh
) which you want them to be checked-out with LF or with CRLF you can use .gitattributes
To sum-up for me the best practice is:
git grep -I --files-with-matches --perl-regexp '\r' HEAD
(Note: on windows clients works only through git-bash
and on linux clients only if compiled using --with-libpcre
in ./configure
). core.autocrlf=input
(--- update 3 --).gitattributes
core.autocrlf
described above to its default values..gitattributes
. git-clients of IDEs may ignore them or treat them differrently.As said some things can be added in git attributes:
# Always checkout with LF
*.sh text eol=lf
# Always checkout with CRLF
*.bat text eol=crlf
I think some other safe options for .gitattributes
instead of using auto-detection for binary files:
-text
(e.g for *.zip
or *.jpg
files: Will not be treated as text. Thus no line-ending conversions will be attempted. Diff might be possible through conversion programs)text !eol
(e.g. for *.java
,*.html
: Treated as text, but eol style preference is not set. So client setting is used.)-text -diff -merge
(e.g for *.hugefile
: Not treated as text. No diff/merge possible)One painful example of a client that will commit files wrongly:
netbeans 8.2 (on windows), will wrongly commit all text files with CRLFs, unless you have explicitly set core.autocrlf
as global. This contradicts to the standard git client behaviour, and causes lots of problems later, while updating/merging. This is what makes some files appear different (although they are not) even when you revert.
The same behaviour in netbeans happens even if you have added correct .gitattributes
to your project.
Using the following command after a commit, will at least help you detect early whether your git repo has line ending issues: git grep -I --files-with-matches --perl-regexp '\r' HEAD
I have spent hours to come up with the best possible use of .gitattributes
, to finally realize, that I cannot count on it.
Unfortunately, as long as JGit-based editors exist (which cannot handle .gitattributes
correctly), the safe solution is to force LF everywhere even on editor-level.
Use the following anti-CRLF
disinfectants.
windows/linux clients: core.autocrlf=input
committed .gitattributes
: * text=auto eol=lf
committed .editorconfig
(http://editorconfig.org/) which is kind of standardized format, combined with editor plugins:
In the converter of the chosen solution, you should add values.Clone() otherwise the parameters in the command end null
public class YourConverter : IMultiValueConverter
{
public object Convert(object[] values, ...)
{
return values.Clone();
}
...
}
It's hard to do this.
There is a min-height:
css style, but it doesn't work in all browsers. You can use it, but the biggest problem is that you will need to set it to something like 90% or numbers like that (percents), but the top and bottom divs use fixed pixel sizes, and you won't be able to reconcile them.
var minHeight = $(window).height() -
$('#a').outerHeight(true) -
$('#c').outerHeight(true));
if($('#b').height() < minHeight) $('#b').height(minHeight);
I know a
and c
have fixed heights, but I rather measure them in case they change later.
Also, I am measuring the height of b
(I don't want to make is smaller after all), but if there is an image in there that did not load the height can change, so watch out for things like that.
It may be safer to do:
$('#b').prepend('<div style="float: left; width: 1px; height: ' + minHeight + 'px;"> </div>');
Which simply adds an element into that div with the correct height - that effectively acts as min-height even for browsers that don't have it. (You may want to add the element into your markup, and then just control the height of it via javascript instead of also adding it that way, that way you can take it into account when designing the layout.)
I'll add another possible solution here, which is what worked in my case.
I found there was a process called SpiceWorksEventProcessor running, which was tying up port 5555, and apparently being read by adb as an emulator. Killing that process was what finally removed that stubborn emulator device for me.
I'm not sure what this thing is, but if you have it, it might be the cause of your offline emulator.

In answer to your first question, it should be as simple as replacing:
when(LoggerFactory.getLogger(GoodbyeController.class)).thenReturn(loggerMock);
with
when(LoggerFactory.getLogger(any(Class.class))).thenReturn(loggerMock);
Regarding your second question (and possibly the puzzling behavior with the first), I think the problem is that logger is static. So,
private static Logger logger = LoggerFactory.getLogger(GoodbyeController.class);
is executed when the class is initialized, not the when the object is instantiated. Sometimes this can be at about the same time, so you'll be OK, but it's hard to guarantee that. So you set up LoggerFactory.getLogger to return your mock, but the logger variable may have already been set with a real Logger object by the time your mocks are set up.
You may be able to set the logger explicitly using something like ReflectionTestUtils (I don't know if that works with static fields) or change it from a static field to an instance field. Either way, you don't need to mock LoggerFactory.getLogger because you'll be directly injecting the mock Logger instance.
You can specify git log
options to show only the last commit, -1
, and a format that includes only the commit ID, like this:
git log -1 --format=%H
If you prefer the shortened commit ID:
