Make sure you have no display property set in the li
tag in my case I had a display: flex
property on my li
tag for some reason.
var bombout=0;
var checkArr=[];
var arr=[];
while(arr.length < 8 && bombout<100){

arr.push(randomNumber);
}
}?

Laravel raw sql – Insert query:
lets create a get link to insert data which is accessible through url . so our link name is ‘insertintodb’ and inside that function we use db class . db class helps us to interact with database . we us db class static function insert . Inside insert function we will write our PDO query to insert data in database . in below query we will insert ‘ my title ‘ and ‘my content’ as data in posts table .
put below code in your web.php file inside routes directory :
Route::get('/insertintodb',function(){
DB::insert('insert into posts(title,content) values (?,?)',['my title','my content']);
});
Now fire above insert query from browser link below :
localhost/yourprojectname/insertintodb
You can see output of above insert query by going into your database table .you will find a record with id 1 .
Laravel raw sql – Read query :
Now , lets create a get link to read data , which is accessible through url . so our link name is ‘readfromdb’. we us db class static function read . Inside read function we will write our PDO query to read data from database . in below query we will read data of id ‘1’ from posts table .
put below code in your web.php file inside routes directory :
Route::get('/readfromdb',function() {
$result = DB::select('select * from posts where id = ?', [1]);
var_dump($result);
});
now fire above read query from browser link below :
localhost/yourprojectname/readfromdb
Including the implementation file (test.c
) causes it to be prepended to your main.c and complied there and then again separately. So, the function test
has two definitions -- one in the object code of main.c
and once in that of test.c
, which gives you a ODR violation. You need to create a header file containing the declaration of test
and include it in main.c
:
/* test.h */
#ifndef TEST_H
#define TEST_H
void test(); /* declaration */
#endif /* TEST_H */
This should work:
window.onload = function() {
document.getElementById('about').className = 'expand';
};
Or if you're using jQuery:
$(function() {
$('#about').addClass('expand');
});
Folks you can see what the optimizer is doing by running a plan. The generic format of looking into a plan is from the MongoDB documentation . i.e. Cursor.plan()
. If you really want to dig deeper you can do a cursor.plan(true)
for more details.
Having said that if you have an index, your db.col.find().sort({"field":-1}).limit(1)
will read one index entry - even if the index is default ascending and you wanted the max entry and one value from the collection.
In other words the suggestions from @yogesh is correct.

After a bit of time (and more searching), I found this blog entry by Jomo Fisher.
One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:
Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
[Snip]
The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:
<startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup>
So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy
attribute reverts back to CLR 2.0 loading.
You can use the -p
parameter, which is documented as:
-p, --parents
no error if existing, make parent directories as needed
So:
mkdir -p "$BACKUP_DIR/$client/$year/$month/$day"
Well, the most likely difference is that you still have to do an actual lookup of localhost
somewhere.
If you use 127.0.0.1
, then (intelligent) software will just turn that directly into an IP address and use it. Some implementations of gethostbyname
will detect the dotted format (and presumably the equivalent IPv6 format) and not do a lookup at all.
Otherwise, the name has to be resolved. And there's no guarantee that your hosts
file will actually be used for that resolution (first, or at all) so localhost
may become a totally different IP address.
By that I mean that, on some systems, a local hosts
file can be bypassed. The host.conf
file controls this on Linux (and many other Unices).

I spent a while developing a better solution to this. It can handle very big numbers but once they get over 16 digits you have pass the number in as a string. Something about the limit of JavaScript numbers.
function numberToEnglish( n ) {
var string = n.toString(), units, tens, scales, start, end, chunks, chunksLen, chunk, ints, i, word, words, and = 'and';
/* Remove spaces and commas */
string = string.replace(/[, ]/g,"");
/* Is number zero? */
if( parseInt( string ) === 0 ) {
return 'zero';
}
/* Array of units as words */
units = [ '', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen' ];
/* Array of tens as words */
tens = [ '', '', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety' ];
/* Array of scales as words */
scales = [ '', 'thousand', 'million', 'billion', 'trillion', 'quadrillion', 'quintillion', 'sextillion', 'septillion', 'octillion', 'nonillion', 'decillion', 'undecillion', 'duodecillion', 'tredecillion', 'quatttuor-decillion', 'quindecillion', 'sexdecillion', 'septen-decillion', 'octodecillion', 'novemdecillion', 'vigintillion', 'centillion' ];
/* Split user argument into 3 digit chunks from right to left */
start = string.length;
chunks = [];
while( start > 0 ) {
end = start;
chunks.push( string.slice( ( start = Math.max( 0, start - 3 ) ), end ) );
}
/* Check if function has enough scale words to be able to stringify the user argument */
chunksLen = chunks.length;
if( chunksLen > scales.length ) {
return '';
}
/* Stringify each integer in each chunk */
words = [];
for( i = 0; i < chunksLen; i++ ) {
chunk = parseInt( chunks[i] );
if( chunk ) {
/* Split chunk into array of individual integers */
ints = chunks[i].split( '' ).reverse().map( parseFloat );
/* If tens integer is 1, i.e. 10, then add 10 to units integer */
if( ints[1] === 1 ) {
ints[0] += 10;
}
/* Add scale word if chunk is not zero and array item exists */
if( ( word = scales[i] ) ) {
words.push( word );
}
/* Add unit word if array item exists */
if( ( word = units[ ints[0] ] ) ) {
words.push( word );
}
/* Add tens word if array item exists */
if( ( word = tens[ ints[1] ] ) ) {
words.push( word );
}
/* Add 'and' string after units or tens integer if: */
if( ints[0] || ints[1] ) {
/* Chunk has a hundreds integer or chunk is the first of multiple chunks */
if( ints[2] || ! i && chunksLen ) {
words.push( and );
}
}
/* Add hundreds word if array item exists */
if( ( word = units[ ints[2] ] ) ) {
words.push( word + ' hundred' );
}
}
}
return words.reverse().join( ' ' );
}

Suppose you bound your combobox to a List<Person>
List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource
pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;
Of course this means that you need to add a checking code when you try to use the info from the combobox
if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
MessageBox.Show("Please select a person name");
else
......
The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection
In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to
DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);
To change the Modal position in the viewport you can target the Modal div id, in this example this id is myModal3
<div id="modal3" class="modal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
#myModal3 {
top:5%;
right:50%;
outline: none;
overflow:hidden;
}
You could use the TIMEDIFF()
and the TIME_TO_SEC()
functions as follows:
SELECT TIME_TO_SEC(TIMEDIFF('2010-08-20 12:01:00', '2010-08-20 12:00:00')) diff;
+------+
| diff |
+------+
| 60 |
+------+
1 row in set (0.00 sec)
You could also use the UNIX_TIMESTAMP()
function as @Amber suggested in an other answer:
SELECT UNIX_TIMESTAMP('2010-08-20 12:01:00') -
UNIX_TIMESTAMP('2010-08-20 12:00:00') diff;
+------+
| diff |
+------+
| 60 |
+------+
1 row in set (0.00 sec)
If you are using the TIMESTAMP
data type, I guess that the UNIX_TIMESTAMP()
solution would be slightly faster, since TIMESTAMP
values are already stored as an integer representing the number of seconds since the epoch (Source). Quoting the docs:
When
UNIX_TIMESTAMP()
is used on aTIMESTAMP
column, the function returns the internal timestamp value directly, with no implicit “string-to-Unix-timestamp” conversion.Keep in mind that
TIMEDIFF()
return data type ofTIME
.TIME
values may range from '-838:59:59' to '838:59:59' (roughly 34.96 days)
Better to use:
DELETE tbl FROM tbl INNER JOIN deleted ON tbl.key=deleted.key
The best solution is the attribute selector in CSS (input[type="text"]
) as the others suggested.
But if you have to support Internet Explorer 6, you cannot use it (QuirksMode). Well, only if you have to and also are willing to support it.
In this case your only option seems to be to define classes on input elements.
<input type="text" class="input-box" ... />
<input type="submit" class="button" ... />
...
and target them with a class selector:
input.input-box, textarea { background: cyan; }
Remember that the default delimiter for SQLite is the pipe "|"
sqlite> .separator ";"
sqlite> .import path/filename.txt tablename
http://sqlite.awardspace.info/syntax/sqlitepg01.htm#sqlite010
Adding up to what Micheal has said:
You can use Predicate as follows in filtering collections in java:
public static <T> Collection<T> filter(final Collection<T> target,
final Predicate<T> predicate) {
final Collection<T> result = new ArrayList<T>();
for (final T element : target) {
if (predicate.apply(element)) {
result.add(element);
}
}
return result;
}
one possible predicate can be:
final Predicate<DisplayFieldDto> filterCriteria =
new Predicate<DisplayFieldDto>() {
public boolean apply(final DisplayFieldDto displayFieldDto) {
return displayFieldDto.isDisplay();
}
};
Usage:
final List<DisplayFieldDto> filteredList=
(List<DisplayFieldDto>)filter(displayFieldsList, filterCriteria);
They don't do the same thing. The first one works if obj is of type ClassA or of some subclass of ClassA. The second one will only match objects of type ClassA. The second one will be faster since it doesn't have to check the class hierarchy.
For those who want to know the reason, but don't want to read the article referenced in is vs typeof.
From Github guide: Getting your project to Github:(using Github desktop version)
Set up your project in GitHub Desktop
The easiest way to get your project into GitHub Desktop is to drag the folder which contains your project files onto the main application screen.
If you are dragging in an existing Git repository, you can skip ahead and push your code to GitHub.com.
If the folder isn’t a Git repository yet, GitHub Desktop will prompt you to turn it into a repository. Turning your project into a Git repository won’t delete or ruin the files in your folder—it will simply create some hidden files that allow Git to do its magic.
In Windows it looks like this:(GitHub desktop 3.0.5.2)
this is not the most geeky way but it works.
Assuming the ID is unique:
var result = xmldoc.Element("Customers")
.Elements("Customer")
.Single(x => (int?)x.Attribute("ID") == 2);
You could also use First
, FirstOrDefault
, SingleOrDefault
or Where
, instead of Single
for different circumstances.
Another way to convert an Enum-Type to an int:
enum E
{
A = 1, /* index 0 */
B = 2, /* index 1 */
C = 4, /* index 2 */
D = 4 /* index 3, duplicate use of 4 */
}
void Main()
{
E e = E.C;
int index = Array.IndexOf(Enum.GetValues(e.GetType()), e);
// index is 2
E f = (E)(Enum.GetValues(e.GetType())).GetValue(index);
// f is E.C
}
More complex but independent from the INT values assigned to the enum values.
This is very easy
Button btn = (Button) findViewById(R.id.btn);
btn.setText("MyText");
You can use a Handler to post runnable code. This technique is outlined very nicely here: https://guides.codepath.com/android/Repeating-Periodic-Tasks
One additional tweak worth mentioning: I'm not sure if this is a .NET 4.0 or Visual Studio 2010 feature, but if you're using both you don't need to declare the value parameter for the setter/mutator block of code:
Private _name As String
Public Property Name() As String
Get
Return _name
End Get
Private Set
_name = value
End Set
End Property
To add:
$arr["key"] = "value";
Then simply return $arr
Can't return directly like this way return $arr["key"] = "value";
Here is a nice vanilla JS function I wrote to extract form data as an object. It also has options for inserting additions into the object, and for clearing the form input fields.
const extractFormData = ({ form, clear, add }) => {
return [].slice.call(form.children).filter(node => node.nodeName === 'INPUT')
.reduce((formData, input) => {
const value = input.value
if (clear) { input.value = '' }
return {
...formData,
[input.name]: value
}
}, add)
}
Here is an example of its use with a post request:
submitGrudge(e) {
e.preventDefault()
const form = e.target
const add = { id: Date.now(), forgiven: false }
const grudge = extractFormData({ form, add, clear: true })
// grudge = {
// "name": "Example name",
// "offense": "Example string",
// "date": "2017-02-16",
// "id": 1487877281983,
// "forgiven": false
// }
fetch('http://localhost:3001/api/grudge', {
method: 'post',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(grudge)
})
.then(response => response.json())
.then(grudges => this.setState({ grudges }))
.catch(err => console.log('error: ', err))
}
As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.
var mockFileBrowser = new Mock<FileBrowser>();
instead of
var mockFileBrowser = new Mock<IFileBrowser>();
I was looking for a similar problem and found a better approach of doing this. So here it goes.
You can simply put the following line on the redirection page (say page1.php).
header("Location: URL", TRUE, 307); // Replace URL with to be redirected URL, e.g. final.php
I need this to redirect POST requests for REST API calls. This solution is able to redirect with post data as well as custom header values.
Here is the reference link.
If your script is called myScript.js and you want to pass the first and last name, 'Sean Worthington', as arguments like below:
node myScript.js Sean Worthington
Then within your script you write:
var firstName = process.argv[2]; // Will be set to 'Sean'
var lastName = process.argv[3]; // Will be set to 'Worthington'
I find that adb shell pm uninstall <package>

It looks like you indented so_far = new
too much. Try this:
if guess in word:
print("\nYes!", guess, "is in the word!")
# Create a new variable (so_far) to contain the guess
new = ""
i = 0
for i in range(len(word)):
if guess == word[i]:
new += guess
else:
new += so_far[i]

If you want to perform a hover like event on any HTML element, then you can do it like this.
HTML
<div (mouseenter) ="mouseEnter('div a') " (mouseleave) ="mouseLeave('div A')">
<h2>Div A</h2>
</div>
<div (mouseenter) ="mouseEnter('div b')" (mouseleave) ="mouseLeave('div B')">
<h2>Div B</h2>
</div>
Component
import { Component } from '@angular/core';
@Component({
moduleId: module.id,
selector: 'basic-detail',
templateUrl: 'basic.component.html',
})
export class BasicComponent{
mouseEnter(div : string){
console.log("mouse enter : " + div);
}
mouseLeave(div : string){
console.log('mouse leave :' + div);
}
}
You should use both mouseenter and mouseleave events inorder to implement fully functional hover events in angular 2.
As others have said, it is not possible to out of using post/redirect/get. But at the same time it is quite easy to do what you want to do server side.
In your POST page you simply validate the user input but do not act on it, instead you copy it into a SESSION array. You then redirect back to the main submission page again. Your main submission page starts by checking to see if the SESSION array that you are using exists, and if so copy it into a local array and unset it. From there you can act on it.
This way you only do all your main work once, achieving what you want to do.
I took a different approach. I switched to use $.post and the error has gone since then.
For Windows users, enter the following command :
set JAVA_OPTS=-Dhttp.proxySet=true -Dhttp.proxyHost=[Your Proxy server] -Dhttp.proxyPort=8080
You can convert List to String array by using this method:
Object[] stringlist=list.toArray();
The complete example:
ArrayList<String> list=new ArrayList<>();
list.add("Abc");
list.add("xyz");
Object[] stringlist=list.toArray();
for(int i = 0; i < stringlist.length ; i++)
{
Log.wtf("list data:",(String)stringlist[i]);
}
Do the following on your linux box where java works (if u like the terminal way of doing things)
cd ~
mkdir decompiled_code && cd decompiled_code
wget https://bitbucket.org/mstrobel/procyon/downloads/procyon-decompiler-0.5.36.jar
java -jar procyon-decompiler-0.5.36.jar /Path/to/your/jar -o .
NOTE : as @Richard commented "this may be illegal depending on whether you own the copyright to the jar, the country you live in and your purpose for doing it."
If you can't use JodaTime, you can do the following:
Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);
int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);
Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.
Replace void *disconnectFunc;
with void (*disconnectFunc)();
to declare function pointer type variable. Or even better use a typedef
:
typedef void (*func_t)(); // pointer to function with no args and void return
...
func_t fptr; // variable of pointer to function
...
void D::setDisconnectFunc( func_t func )
{
fptr = func;
}
void D::disconnected()
{
fptr();
connected = false;
}
You must add this code in global.aspx:
protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
HttpContext.Current.Response.End();
}
}
Simple solution is to run this query:
mysql -h yourhostname -u username -p databasename < yoursqlfile.sql
And if you want to import with progress bar, try this:
pv yoursqlfile.sql | mysql -uxxx -pxxxx databasename
1st: If you know that your code isn't right, you should fix it before do anything!
You could do something like this:
function validateForm() {
var radios = document.getElementsByName("yesno");
var formValid = false;
var i = 0;
while (!formValid && i < radios.length) {
if (radios[i].checked) formValid = true;
i++;
}
if (!formValid) alert("Must check some option!");
return formValid;
}?

Another option:
string s2 = String.Join("," + Environment.NewLine, s1.Split(','));
You can't. The emulator does not support Bluetooth, as mentioned in the SDK's docs and several other places. Android emulator does not have bluetooth capabilities".
You can only use real devices.
Emulator Limitations
The functional limitations of the emulator include:
Refer to the documentation
nodeName
is the attribute you are looking for. For example:
var elt = document.getElementById('foo');
console.log(elt.nodeName);
Note that nodeName
returns the element name capitalized and without the angle brackets, which means that if you want to check if an element is an <div>
element you could do it as follows:
elt.nodeName == "DIV"
While this would not give you the expected results:
elt.nodeName == "<div>"
Here is another way to use SQL SELECT
statement in VBA:
sSQL = "SELECT Variable FROM GroupTable WHERE VariableCode = '" & Me.comboBox & "'"
Set rs = CurrentDb.OpenRecordset(sSQL)
On Error GoTo resultsetError
dbValue = rs!Variable
MsgBox dbValue, vbOKOnly, "RS VALUE"
resultsetError:
MsgBox "Error Retrieving value from database",VbOkOnly,"Database Error"
The names and values are confusing. If you are looking for the total free memory you will have to calculate this value by your self. It is not what you get from freeMemory();
.
See the following guide:
Total designated memory, this will equal the configured -Xmx value:
Runtime.getRuntime().maxMemory();
Current allocated free memory, is the current allocated space ready for new objects. Caution this is not the total free available memory:
Runtime.getRuntime().freeMemory();
Total allocated memory, is the total allocated space reserved for the java process:
Runtime.getRuntime().totalMemory();
Used memory, has to be calculated:
usedMemory = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory();
Total free memory, has to be calculated:
freeMemory = Runtime.getRuntime().maxMemory() - usedMemory;
A picture may help to clarify:
If you're looking for a way to immutably change the collection (as I was when I found your question), you might take a look at immutability-helper, a library forked from the original React util. In your case, you would accomplish what you mentioned via the following:
var update = require('immutability-helper')
var arr = [{id: 1, name: "Person 1"}, {id:2, name:"Person 2"}]
var newArray = update(arr, { 0: { name: { $set: 'New Name' } } })
//=> [{id: 1, name: "New Name"}, {id:2, name:"Person 2"}]
Your best bet is the RandomLib library by ircmaxell.
Usage example:
$factory = new RandomLib\Factory;
$generator = $factory->getGenerator(new SecurityLib\Strength(SecurityLib\Strength::MEDIUM));
$passwordLength = 8; // Or more
$randomPassword = $generator->generateString($passwordLength);
It produces strings which are more strongly random than the normal randomness functions like shuffle()
and rand()
(which is what you generally want for sensitive information like passwords, salts and keys).
As of Oct 2019, SQL Server Management Studio, they did not upgraded the SSMS to add create ER Diagram feature.
I would suggest try using DBWeaver from here :
I am using Mac and Windows both and I was able to download the community edition and logged into my SQL server database and was able to create the ER diagram using the DB Weaver.
If you use "axios": "^0.17.1" version you can do like this:
Create instance of axios:
// Default config options
const defaultOptions = {
baseURL: <CHANGE-TO-URL>,
headers: {
'Content-Type': 'application/json',
},
};
// Create instance
let instance = axios.create(defaultOptions);
// Set the AUTH token for any request
instance.interceptors.request.use(function (config) {
const token = localStorage.getItem('token');
config.headers.Authorization = token ? `Bearer ${token}` : '';
return config;
});
Then for any request the token will be select from localStorage and will be added to the request headers.
I'm using the same instance all over the app with this code:
import axios from 'axios';
const fetchClient = () => {
const defaultOptions = {
baseURL: process.env.REACT_APP_API_PATH,
method: 'get',
headers: {
'Content-Type': 'application/json',
},
};
// Create instance
let instance = axios.create(defaultOptions);
// Set the AUTH token for any request
instance.interceptors.request.use(function (config) {
const token = localStorage.getItem('token');
config.headers.Authorization = token ? `Bearer ${token}` : '';
return config;
});
return instance;
};
export default fetchClient();
Good luck.

The HashMap has forEach
as part of its structure. You can use that with a lambda expression to print out the contents in a one liner such as:
map.forEach((k,v)-> System.out.println(k+", "+v));
or
map.forEach((k,v)-> System.out.println("key: "+k+", value: "+v));
You should look at a job scheduled using the SQL Server Agent.
Sometimes when your table has a similar name to the database name you should use back tick. so instead of:
INSERT INTO books.book(field1, field2) VALUES ('value1', 'value2');
You should have this:
INSERT INTO `books`.`book`(`field1`, `field2`) VALUES ('value1', 'value2');
I suggest use the common way of import.
First I will explain the way it called "relative import" maybe this way cause of some error
Second I will explain the common way of import.
FIRST:
In go version >= 1.12 there is some new tips about import file and somethings changed.
1- You should put your file in another folder for example I create a file in "model" folder and the file's name is "example.go"
2- You have to use uppercase when you want to import a file!
3- Use Uppercase for variables, structures and functions that you want to import in another files
Notice: There is no way to import the main.go in another file.
file directory is:
root
|_____main.go
|_____model
|_____example.go
this is a example.go:
package model
import (
"time"
)
var StartTime = time.Now()
and this is main.go you should use uppercase when you want to import a file. "Mod" started with uppercase
package main
import (
Mod "./model"
"fmt"
)
func main() {
fmt.Println(Mod.StartTime)
}
NOTE!!!
NOTE: I don't recommend this this type of import!
SECOND:
(normal import)
the better way import file is:
your structure should be like this:
root
|_____github.com
|_________Your-account-name-in-github
| |__________Your-project-name
| |________main.go
| |________handlers
| |________models
|
|_________gorilla
|__________sessions
and this is a example:
package main
import (
"github.com/gorilla/sessions"
)
func main(){
//you can use sessions here
}
so you can import "github.com/gorilla/sessions" in every where that you want...just import it.
OK,
Here's a dinosaur method for you on Office 2010.
Write the full address you want using concatenate (the "&" method of combining text).
Do this for all the addresses you need. It should look like:
="="&"'\FULL NETWORK ADDRESS including [Spreadsheet Name]"&W3&"'!$w4"
The W3 is a dynamic reference to what sheet I am using, the W4 is the cell I want to get from the sheet.
Once you have this, start up a macro recording session. Copy the cell and paste it into another. I pasted it into a merged cell and it gave me the classic "Same size" error. But one thing it did was paste the resulting text from my concatenate (including that extra "=").
Copy over however many you did this for. Then, go into each pasted cell, select he text and just hit enter. It updates it to an active direct reference.
Once you have finished, put the cursor somewhere nice and stop the macro. Assign it to a button and you are done.
It is a bit of a PITA to do this the first time, but once you have done it, you have just made the square peg fit that daamned round hole.
This error means that the upstream repository has made commits that would be lost if you were to push. First do a "git pull" to merge, and then push again.
What? The person asked for Linux specific, and the equivalent of getpid(). Not BSD or Apple. The answer is gettid() and returns an integral type. You will have to call it using syscall(), like this:
#include <sys/types.h>
#include <unistd.h>
#include <sys/syscall.h>
....
pid_t x = syscall(__NR_gettid);
While this may not be portable to non-linux systems, the threadid is directly comparable and very fast to acquire. It can be printed (such as for LOGs) like a normal integer.
I had this issue today, and for me the problem was that I had allocated too much memory:
-Xmx1024M -XX:MaxPermSize=1024m
Once I reduced the PermGen space, everything worked fine:
-Xmx1024M -XX:MaxPermSize=512m
I know that doesn't look like much of a difference, but my machine only has 4GB of RAM, and apparently that was the straw that broke the camel's back. The Java VM was failing immediately upon every action because it was failing to allocate the memory.
The size arguments are in pixels. So, to double your example's marker size the fifth argument to the MarkerImage constructor would be:
new google.maps.Size(42,68)
I find it easiest to let the map API figure out the other arguments, unless I need something other than the bottom/center of the image as the anchor. In your case you could do:
var pinIcon = new google.maps.MarkerImage(
"http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(42, 68)
);
I solved this problem very simply using a little hack in the adapter. Here is my code:
public class MyPagerAdapter extends FragmentStatePagerAdapter
{
public static int LOOPS_COUNT = 1000;
private ArrayList<Product> mProducts;
public MyPagerAdapter(FragmentManager manager, ArrayList<Product> products)
{
super(manager);
mProducts = products;
}
@Override
public Fragment getItem(int position)
{
if (mProducts != null && mProducts.size() > 0)
{
position = position % mProducts.size(); // use modulo for infinite cycling
return MyFragment.newInstance(mProducts.get(position));
}
else
{
return MyFragment.newInstance(null);
}
}
@Override
public int getCount()
{
if (mProducts != null && mProducts.size() > 0)
{
return mProducts.size()*LOOPS_COUNT; // simulate infinite by big number of products
}
else
{
return 1;
}
}
}
And then, in the ViewPager, we set current page to the middle:
mAdapter = new MyPagerAdapter(getSupportFragmentManager(), mProducts);
mViewPager.setAdapter(mAdapter);
mViewPager.setCurrentItem(mViewPager.getChildCount() * MyPagerAdapter.LOOPS_COUNT / 2, false); // set current item in the adapter to middle
One could write a collector that collects elements in reversed order:
public static <T> Collector<T, ?, Stream<T>> reversed() {
return Collectors.collectingAndThen(Collectors.toList(), list -> {
Collections.reverse(list);
return list.stream();
});
}
And use it like this:
Stream.of(1, 2, 3, 4, 5).collect(reversed()).forEach(System.out::println);
Original answer (contains a bug - it does not work correctly for parallel streams):
A general purpose stream reverse method could look like:
public static <T> Stream<T> reverse(Stream<T> stream) {
LinkedList<T> stack = new LinkedList<>();
stream.forEach(stack::push);
return stack.stream();
}
I am using Google API for .Net, but no doubt you can find the same way to obtain this information using other version of API. As user872858 mentioned, scope userinfo.profile has been deprecated (google article) .
To obtain user profile info I use following code (re-written part from google's example):
IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(
new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = Secrets,
Scopes = new[] { PlusService.Scope.PlusLogin,"https://www.googleapis.com/auth/plus.profile.emails.read" }
});
TokenResponse _token = flow.ExchangeCodeForTokenAsync("", code, "postmessage",
CancellationToken.None).Result;
// Create an authorization state from the returned token.
context.Session["authState"] = _token;
// Get tokeninfo for the access token if you want to verify.
Oauth2Service service = new Oauth2Service(
new Google.Apis.Services.BaseClientService.Initializer());
Oauth2Service.TokeninfoRequest request = service.Tokeninfo();
request.AccessToken = _token.AccessToken;
Tokeninfo info = request.Execute();
if (info.VerifiedEmail.HasValue && info.VerifiedEmail.Value)
{
flow = new GoogleAuthorizationCodeFlow(
new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = Secrets,
Scopes = new[] { PlusService.Scope.PlusLogin }
});
UserCredential credential = new UserCredential(flow,
"me", _token);
_token = credential.Token;
_ps = new PlusService(
new Google.Apis.Services.BaseClientService.Initializer()
{
ApplicationName = "Your app name",
HttpClientInitializer = credential
});
Person userProfile = _ps.People.Get("me").Execute();
}
Than, you can access almost anything using userProfile.
UPDATE: To get this code working you have to use appropriate scopes on google sign in button. For example my button:
<button class="g-signin"
data-scope="https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.profile.emails.read"
data-clientid="646361778467-nb2uipj05c4adlk0vo66k96bv8inqles.apps.googleusercontent.com"
data-accesstype="offline"
data-redirecturi="postmessage"
data-theme="dark"
data-callback="onSignInCallback"
data-cookiepolicy="single_host_origin"
data-width="iconOnly">
</button>
The branch name in Git is case sensitive. To see the names of your branches that Git 'sees' (including the correct casing), use:
git branch -vv
... and now that you can see the correct branch name to use, do this:
git pull origin BranchName
where 'BranchName' is the name of your branch. Ensure that you match the case correctly
So in the OP's (Original Poster's) case, the command would be:
git pull origin DownloadManager
You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:
<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>
</body>
</html>
Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.
app-routing.module.ts
const routes: Routes = [
{ path: 'products', component: ProductsComponent },
{ path: 'product/:id', component: ProductDetailsComponent },
{ path: '', redirectTo: '/products', pathMatch: 'full' },
];
In controller you can navigate like this,
this.router.navigate(['/products', productId]);
It will land you to path like this: http://localhost:4200/products/product-id
If you are using RemoteDriver things are different. From http://element34.ca/blog/iedriverserver-webdriver-and-python :
You will need to start the server using a line like
java -jar selenium-server-standalone-2.26.0.jar -Dwebdriver.ie.driver=C:\Temp\IEDriverServer.exe
I found that if the IEDriverServer.exe was in C:\Windows\System32\
or its subfolders, it couldn't be found automatically (even though System32 was in the %PATH%
) or explicitly using the -D flag.

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.
MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx
If
throwOnFirstException
is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. IfthrowOnFirstException
is false, this overload will aggregate any exceptions thrown into anAggregateException
, such that one callback throwing an exception will not prevent other registered callbacks from being executed.
The variable name is also wrong because Cancel is called on CancellationTokenSource
not the token itself and the source changes state of each token it manages.

This function worked perfectly for me. It detects Edge as well.
Originally from this Codepen:
https://codepen.io/gapcode/pen/vEJNZN
/**
* detect IE
* returns version of IE or false, if browser is not Internet Explorer
*/
function detectIE() {
var ua = window.navigator.userAgent;
// Test values; Uncomment to check result …
// IE 10
// ua = 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)';
// IE 11
// ua = 'Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko';
// Edge 12 (Spartan)
// ua = 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36 Edge/12.0';
// Edge 13
// ua = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2486.0 Safari/537.36 Edge/13.10586';
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
// IE 10 or older => return version number
return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}
var trident = ua.indexOf('Trident/');
if (trident > 0) {
// IE 11 => return version number
var rv = ua.indexOf('rv:');
return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}
var edge = ua.indexOf('Edge/');
if (edge > 0) {
// Edge (IE 12+) => return version number
return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}
// other browser
return false;
}
Then you can use if (detectIE()) { /* do IE stuff */ }
in your code.
Use org.springframework.web.context.request.WebRequest
as a parameter in your controller method, it provides the method getParameterMap()
, the advantage is that you do not tight your application to the Servlet API, the WebRequest is a example of JavaEE pattern Context Object.
You can very easily iterate over dictionaries, too:
for team, scores in NL_East.iteritems():
runs_scored = float(scores[0])
runs_allowed = float(scores[1])
win_percentage = round((runs_scored**2)/((runs_scored**2)+(runs_allowed**2))*1000)
print '%s: %.1f%%' % (team, win_percentage)
try this one, it is working fine for me.

Have you run through Vim's built-in tutorial? If not, drop to the command-line and type vimtutor
. It's a great way to learn the initial commands.
Vim has an incredible amount of flexibility and power and, if you're like most vim users, you'll learn a lot of new commands and forget old ones, then relearn them. The built-in help is good and worthy of periodic browsing to learn new stuff.
There are several good FAQs and cheatsheets for vim on the internet. I'd recommend searching for vim + faq
and vim + cheatsheet
. Cheat-Sheets.org#vim is a good source, as is Vim Tips wiki.
There is a round()
function, also fround()
, which will round to the nearest integer expressed as a double. But that is not what you want.
I had the same problem and wrote this:

/* ===============
**
** Rounds double <value> to <nsig> significant figures. Always rounds
** away from zero, so -2.6 to 1 sig fig will become -3.0.
**
** <nsig> should be in the range 1 - 15
*/
{
double a, b;
long long i;
int neg = 0;
if(!value) return value;
if(value < 0.0)
{
value = -value;
neg = 1;
}
i = nsig - log10(value);
if(i) a = pow(10.0, (double)i);
else a = 1.0;
b = value * a;
i = b + 0.5;
value = i / a;
return neg ? -value : value;
}
I use both Clang and GCC, I find Clang has some useful warnings, but for my own ray-tracing benchmarks - its consistently 5-15% slower then GCC (take that with grain of salt of course, but attempted to use similar optimization flags for both).
So for now I use Clang static analysis and its warnings with complex macros: (though now GCC's warnings are pretty much as good - gcc4.8 - 4.9).
Some considerations:
***** - these areas are in active development and may soon be supported

If you want to use SQL Express 2012 LocalDB from VS2010 you must have this patch installed http://www.microsoft.com/en-us/download/details.aspx?id=27756
Just like mentioned in the comments above I too had Microsoft .NET Framework Version 4.0.30319 SP1Rel and since its mentioned everywhere that you need "Framework 4.0.2 or Above" I thought I am good to go...
However, when I explicitly downloaded that 4.0.2 patch and installed it I got it working....
Ok it turns out I was doing something stupid. I hadn't appended the new file name to the path.
I had
rootDirectory = "C:\\safesite_documents"
but it should have been
rootDirectory = "C:\\safesite_documents\\newFile.jpg"
Sorry it was a stupid mistake as always.
Using ping in C# is achieved by using the method Ping.Send(System.Net.IPAddress)
, which runs a ping request to the provided (valid) IP address or URL and gets a response which is called an Internet Control Message Protocol (ICMP) Packet. The packet contains a header of 20 bytes which contains the response data from the server which received the ping request. The .Net framework System.Net.NetworkInformation
namespace contains a class called PingReply
that has properties designed to translate the ICMP
response and deliver useful information about the pinged server such as:
The following is a simple example using WinForms
to demonstrate how ping works in c#. By providing a valid IP address in textBox1
and clicking button1
, we are creating an instance of the Ping
class, a local variable PingReply
, and a string to store the IP or URL address. We assign PingReply
to the ping Send
method, then we inspect if the request was successful by comparing the status of the reply to the property IPAddress.Success
status. Finally, we extract from PingReply
the information we need to display for the user, which is described above.
using System;
using System.Net.NetworkInformation;
using System.Windows.Forms;
namespace PingTest1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Ping p = new Ping();
PingReply r;
string s;
s = textBox1.Text;
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
lblResult.Text = "Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful"
+ " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n";
}
}
private void textBox1_Validated(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(textBox1.Text) || textBox1.Text == "")
{
MessageBox.Show("Please use valid IP or web address!!");
}
}
}
}

I hope, it will help to solve your problem.
you can just do $scope.todo = Todo.get({ id: 123 })
. .get()
and .query()
on a Resource return an object immediately and fill it with the result of the promise later (to update your template). It's not a typical promise which is why you need to either use a callback or the $promise property if you have some special code you want executed after the call. But there is no need to assign it to your scope in a callback if you are only using it in the template.

As this has already been properly answered, I'd just add the following site as a reference:
You can search for "check", for example.
FileReader
uses Java's platform default encoding, which depends on the system settings of the computer it's running on and is generally the most popular encoding among users in that locale.
If this "best guess" is not correct then you have to specify the encoding explicitly. Unfortunately, FileReader
does not allow this (major oversight in the API). Instead, you have to use new InputStreamReader(new FileInputStream(filePath), encoding)
and ideally get the encoding from metadata about the file.
Deep Cloning is your answer, which requires implementing the Cloneable
interface and overriding the clone()
method.
public class DummyBean implements Cloneable {
private String dummy;
public void setDummy(String dummy) {
this.dummy = dummy;
}
public String getDummy() {
return dummy;
}
@Override
public Object clone() throws CloneNotSupportedException {
DummyBean cloned = (DummyBean)super.clone();
cloned.setDummy(cloned.getDummy());
// the above is applicable in case of primitive member types like String
// however, in case of non primitive types
// cloned.setNonPrimitiveType(cloned.getNonPrimitiveType().clone());
return cloned;
}
}
You will call it like this
DummyBean dumtwo = dum.clone();
+1 Database
Forms in your app can even re-translate themselves on the fly if corrections are made to the database.
We used a system where all the controls were mapped in an XML file (one per form) to language resource IDs, but all the IDs were in the database.
Basically, instead of having each control hold the ID (implementing an interface, or using the tag property in VB6), we used the fact that in .NET, the control tree was easily discoverable through reflection. A process when the form loaded would build the XML file if it was missing. The XML file would map the controls to their resource IDs, so this simply needed to be filled in and mapped to the database. This meant that there was no need to change the compiled binary if something was not tagged, or if it needed to be split to another ID (some words in English which might be used as both nouns and verbs might need to translate to two different words in the dictionary and not be re-used, but you might not discover this during initial assignment of IDs). But the fact is that the whole translation process becomes completely independent of your binary (every form has to inherit from a base form which knows how to translate itself and all its controls).
The only ones where the app gets more involved is when a phase with insertion points is used.
The database translation software was your basic CRUD maintenance screen with various workflow options to facilitate going through the missing translations, etc.
For current date just use UNIX_TIMESTAMP()
in your MySQL query.
I had to use this after the flush to get the last insert id:
$em->persist($user);
$em->flush();
$user->getId();
nope. are you trying to do some aggregation? if so, you could do something like this to get what you need
;with a as
(
select sum(IntField) as Total
from Table
group by CharField
)
select *, a.Total
from Table t
inner join a
on t.Field=a.Field
Technically, the Integrity attribute helps with just that - it enables the proper verification of the data source. That is, it merely allows the browser to verify the numbers in the right source file with the amounts requested by the source file located on the CDN server.
Going a bit deeper, in case of the established encrypted hash value of this source and its checked compliance with a predefined value in the browser - the code executes, and the user request is successfully processed.
Crossorigin attribute helps developers optimize the rates of CDN performance, at the same time, protecting the website code from malicious scripts.
In particular, Crossorigin downloads the program code of the site in anonymous mode, without downloading cookies or performing the authentication procedure. This way, it prevents the leak of user data when you first load the site on a specific CDN server, which network fraudsters can easily replace addresses.

You cannot open in a new tab programmatically, it's a browser functionality. You can open a link in an external window . Have a look here
this is what i did
first execute create database x
. x is the name of your old database eg the name of the mdf.
Then open sql sever configration and stop the sql sever.
There after browse to the location of your new created database it should be under program file, in my case is
C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQL\MSSQL\DATA
and repleace the new created mdf and Idf with the old files/database.
then simply restart the sql server and walla :)

There are many ways to wait in Unity. It is really simple but I think it's worth covering most ways to do these:
1.With a coroutine and WaitForSeconds
.
The is by far the simplest way. Put all the code that you need to wait for some time in a coroutine function then you can wait with WaitForSeconds
. Note that in coroutine function, you call the function with StartCoroutine(yourFunction)
.
Example below will rotate 90 deg, wait for 4 seconds, rotate 40 deg and wait for 2 seconds, and then finally rotate rotate 20 deg.
void Start()
{
StartCoroutine(waiter());
}
IEnumerator waiter()
{
//Rotate 90 deg
transform.Rotate(new Vector3(90, 0, 0), Space.World);
//Wait for 4 seconds
yield return new WaitForSeconds(4);
//Rotate 40 deg
transform.Rotate(new Vector3(40, 0, 0), Space.World);
//Wait for 2 seconds
yield return new WaitForSeconds(2);
//Rotate 20 deg
transform.Rotate(new Vector3(20, 0, 0), Space.World);
}
2.With a coroutine and WaitForSecondsRealtime
.
The only difference between WaitForSeconds
and WaitForSecondsRealtime
is that WaitForSecondsRealtime
is using unscaled time to wait which means that when pausing a game with Time.timeScale
, the WaitForSecondsRealtime
function would not be affected but WaitForSeconds
would.
void Start()
{
StartCoroutine(waiter());
}
IEnumerator waiter()
{
//Rotate 90 deg
transform.Rotate(new Vector3(90, 0, 0), Space.World);
//Wait for 4 seconds
yield return new WaitForSecondsRealtime(4);
//Rotate 40 deg
transform.Rotate(new Vector3(40, 0, 0), Space.World);
//Wait for 2 seconds
yield return new WaitForSecondsRealtime(2);
//Rotate 20 deg
transform.Rotate(new Vector3(20, 0, 0), Space.World);
}
Wait and still be able to see how long you have waited:
3.With a coroutine and incrementing a variable every frame with Time.deltaTime
.
A good example of this is when you need the timer to display on the screen how much time it has waited. Basically like a timer.
It's also good when you want to interrupt the wait/sleep with a boolean
variable when it is true. This is where yield break;
can be used.
bool quit = false;
void Start()
{
StartCoroutine(waiter());
}
IEnumerator waiter()
{
float counter = 0;
//Rotate 90 deg
transform.Rotate(new Vector3(90, 0, 0), Space.World);
//Wait for 4 seconds
float waitTime = 4;
while (counter < waitTime)
{
//Increment Timer until counter >= waitTime
counter += Time.deltaTime;
Debug.Log("We have waited for: " + counter + " seconds");
//Wait for a frame so that Unity doesn't freeze
//Check if we want to quit this function
if (quit)
{
//Quit function
yield break;
}
yield return null;
}
//Rotate 40 deg
transform.Rotate(new Vector3(40, 0, 0), Space.World);
//Wait for 2 seconds
waitTime = 2;
//Reset counter
counter = 0;
while (counter < waitTime)
{
//Increment Timer until counter >= waitTime
counter += Time.deltaTime;
Debug.Log("We have waited for: " + counter + " seconds");
//Check if we want to quit this function
if (quit)
{
//Quit function
yield break;
}
//Wait for a frame so that Unity doesn't freeze
yield return null;
}
//Rotate 20 deg
transform.Rotate(new Vector3(20, 0, 0), Space.World);
}
You can still simplify this by moving the while
loop into another coroutine function and yielding it and also still be able to see it counting and even interrupt the counter.
bool quit = false;
void Start()
{
StartCoroutine(waiter());
}
IEnumerator waiter()
{
//Rotate 90 deg
transform.Rotate(new Vector3(90, 0, 0), Space.World);
//Wait for 4 seconds
float waitTime = 4;
yield return wait(waitTime);
//Rotate 40 deg
transform.Rotate(new Vector3(40, 0, 0), Space.World);
//Wait for 2 seconds
waitTime = 2;
yield return wait(waitTime);
//Rotate 20 deg
transform.Rotate(new Vector3(20, 0, 0), Space.World);
}
IEnumerator wait(float waitTime)
{
float counter = 0;
while (counter < waitTime)
{
//Increment Timer until counter >= waitTime
counter += Time.deltaTime;
Debug.Log("We have waited for: " + counter + " seconds");
if (quit)
{
//Quit function
yield break;
}
//Wait for a frame so that Unity doesn't freeze
yield return null;
}
}
Wait/Sleep until variable changes or equals to another value:
4.With a coroutine and the WaitUntil
function:
Wait until a condition becomes true
. An example is a function that waits for player's score to be 100
then loads the next level.
float playerScore = 0;
int nextScene = 0;
void Start()
{
StartCoroutine(sceneLoader());
}
IEnumerator sceneLoader()
{
Debug.Log("Waiting for Player score to be >=100 ");
yield return new WaitUntil(() => playerScore >= 10);
Debug.Log("Player score is >=100. Loading next Leve");
//Increment and Load next scene
nextScene++;
SceneManager.LoadScene(nextScene);
}
5.With a coroutine and the WaitWhile
function.
Wait while a condition is true
. An example is when you want to exit app when the escape key is pressed.
void Start()
{
StartCoroutine(inputWaiter());
}
IEnumerator inputWaiter()
{
Debug.Log("Waiting for the Exit button to be pressed");
yield return new WaitWhile(() => !Input.GetKeyDown(KeyCode.Escape));
Debug.Log("Exit button has been pressed. Leaving Application");
//Exit program
Quit();
}
void Quit()
{
#if UNITY_EDITOR
UnityEditor.EditorApplication.isPlaying = false;
#else
Application.Quit();
#endif
}
6.With the Invoke
function:
You can call tell Unity to call function in the future. When you call the Invoke
function, you can pass in the time to wait before calling that function to its second parameter. The example below will call the feedDog()
function after 5
seconds the Invoke
is called.
void Start()
{
Invoke("feedDog", 5);
Debug.Log("Will feed dog after 5 seconds");
}
void feedDog()
{
Debug.Log("Now feeding Dog");
}
7.With the Update()
function and Time.deltaTime
.
It's just like #3 except that it does not use coroutine. It uses the Update
function.
The problem with this is that it requires so many variables so that it won't run every time but just once when the timer is over after the wait.
float timer = 0;
bool timerReached = false;
void Update()
{
if (!timerReached)
timer += Time.deltaTime;
if (!timerReached && timer > 5)
{
Debug.Log("Done waiting");
feedDog();
//Set to false so that We don't run this again
timerReached = true;
}
}
void feedDog()
{
Debug.Log("Now feeding Dog");
}
There are still other ways to wait in Unity but you should definitely know the ones mentioned above as that makes it easier to make games in Unity. When to use each one depends on the circumstances.
For your particular issue, this is the solution:
IEnumerator showTextFuntion()
{
TextUI.text = "Welcome to Number Wizard!";
yield return new WaitForSeconds(3f);
TextUI.text = ("The highest number you can pick is " + max);
yield return new WaitForSeconds(3f);
TextUI.text = ("The lowest number you can pick is " + min);
}
And to call/start the coroutine function from your start or Update function, you call it with
StartCoroutine (showTextFuntion());

Use MyISAM for very unimportant data or if you really need those minimal performance advantages. The read performance is not better in every case for MyISAM.
I would personally never use MyISAM at all anymore. Choose InnoDB and throw a bit more hardware if you need more performance. Another idea is to look at database systems with more features like PostgreSQL if applicable.
EDIT: For the read-performance, this link shows that innoDB often is actually not slower than MyISAM: https://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1/
In my case the ajax call was being interfered by the data-plugin tag applied to the table. The data-plugin does background initialization and will give this error when you have it as well as yourTable.DataTable({ ... }); initialization.

To
<table id="myTable" class="table-class" data-source="data-source">

You can use the CSS3 zoom function, but I have not tested it yet with jQuery. Will try now and let you know. UPDATE: tested it, works but it's fun
for (id subview in webView.subviews)
if ([[subview class] isSubclassOfClass: [UIScrollView class]])
((UIScrollView *)subview).bounces = NO;
...seems to work fine.
It'll be accepted to App Store as well.
Update: in iOS 5.x+ there's an easier way - UIWebView
has scrollView
property, so your code can look like this:
webView.scrollView.bounces = NO;
Same goes for WKWebView
.
I encountered with this problem to figure out that I have two references in my XCODE project. Just delete the other reference. Hope this helps

LIBRARY_PATH
is used by gcc before compilation to search directories containing static and shared libraries that need to be linked to your program.
LD_LIBRARY_PATH
is used by your program to search directories containing shared libraries after it has been successfully compiled and linked.
EDIT:
As pointed below, your libraries can be static or shared. If it is static then the code is copied over into your program and you don't need to search for the library after your program is compiled and linked. If your library is shared then it needs to be dynamically linked to your program and that's when LD_LIBRARY_PATH
comes into play.
You can find what is the php.ini file used:
Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)
Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

If, like me, you found that @wiggin answer didn't work and images still did not appear in-line, you can use the 'align' property of the html image tag and some breaks to achieve the desired effect, for example:
# Title
<img align="left" src="./documentation/images/A.jpg" alt="Made with Angular" title="Angular" hspace="20"/>
<img align="left" src="./documentation/images/B.png" alt="Made with Bootstrap" title="Bootstrap" hspace="20"/>
<img align="left" src="./documentation/images/C.png" alt="Developed using Browsersync" title="Browsersync" hspace="20"/>
<br/><br/><br/><br/><br/>
## Table of Contents...
Obviously, you have to use more breaks depending on how big the images are: awful yes, but it worked for me so I thought I'd share.
%f and %g does the same thing. Only difference is that %g is the shorter form of %f. That is the precision after decimal point is larger in %f compared to %g
git status #then file which you need to push git add example.FileExtension
git commit "message is example"
git push -u origin(or whatever name you used) master(or name of some branch where you want to push it)
don't have to use grep either
an example:
sed -n '/searchwords/{s/^\(.\{12\}\).*/\1/g;p}' file
Just to point out that if you throw a checked exception in a code and the catch is few levels above, you need to declare the exception in the signature of each method between you and the catch. So, encapsulation is broken because all functions in the path of throw must know about details of that exception.

Check if you have a android-support-v4.jar
file in YOUR project's lib folder, it should be removed!
In the tutorial, when you have followed the instructions of Adding libraries WITHOUT resources
before doing the coorect Adding libraries WITH resources
you'll get the same error.
(Don't know why someone would do something like that *lookingawayfrommyself* ^^)
So what did fix it in my case, was removing the android-support-v4.jar
from YOUR PROJECT (not the android-support-v7-appcompat project), since this caused some kind of library collision (maybe because in the meantime there was a new version of the suport library).
Just another case, when this error might shows up.
As others have pointed out, you can only use werkzeug.server.shutdown
from a request handler. The only way I've found to shut down the server at another time is to send a request to yourself. For example, the /kill
handler in this snippet will kill the dev server unless another request comes in during the next second:
import requests
from threading import Timer
from flask import request
import time
LAST_REQUEST_MS = 0
@app.before_request
def update_last_request_ms():
global LAST_REQUEST_MS
LAST_REQUEST_MS = time.time() * 1000
@app.route('/seriouslykill', methods=['POST'])
def seriouslykill():
func = request.environ.get('werkzeug.server.shutdown')
if func is None:
raise RuntimeError('Not running with the Werkzeug Server')
func()
return "Shutting down..."
@app.route('/kill', methods=['POST'])
def kill():
last_ms = LAST_REQUEST_MS
def shutdown():
if LAST_REQUEST_MS <= last_ms: # subsequent requests abort shutdown
requests.post('http://localhost:5000/seriouslykill')
else:
pass
Timer(1.0, shutdown).start() # wait 1 second
return "Shutting down..."
FYI : How to download data in CSV from Kibana:
In Kibana--> 1. Go to 'Discover' in left side
Select Index Field (based on your dashboard data) (*** In case if you are not sure which index to select-->go to management tab-->Saved Objects-->Dashboard-->select dashboard name-->scroll down to JSON-->you will see the Index name )
left side you see all the variables available in the data-->click over the variable name that you want to have in csv-->click add-->this variable will be added on the right side of the columns avaliable
Top right section of the kibana-->there is the time filter-->click -->select the duration for which you want the csv
Top upper right -->Reporting-->save this time/variable selection with a new report-->click generate CSV
Go to 'Management' in left side--> 'Reporting'-->download your csv
I prefer this one:
private void UpdateNowProcessing(string nowProcessing)

Invoke(d, nowProcessing);
}
else
{
this.progressDialog.Next(nowProcessing);
}
}
This is called Fixed Header Scrolling. There are a number of documented approaches:
http://www.imaputz.com/cssStuff/bigFourVersion.html
You won't effectively pull this off without JavaScript ... especially if you want cross browser support.
There are a number of gotchyas with any approach you take, especially concerning cross browser/version support.
Edit:
Even if it's not the header you want to fix, but the first row of data, the concept is still the same. I wasn't 100% which you were referring to.
Additional thought I was tasked by my company to research a solution for this that could function in IE7+, Firefox, and Chrome.
After many moons of searching, trying, and frustration it really boiled down to a fundamental problem. For the most part, in order to gain the fixed header, you need to implement fixed height/width columns because most solutions involve using two separate tables, one for the header which will float and stay in place over the second table that contains the data.
//float this one right over second table
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
</table>
<table>
//Data
</table>
An alternative approach some try is utilize the tbody and thead tags but that is flawed too because IE will not allow you put a scrollbar on the tbody which means you can't limit its height (so stupid IMO).
<table>
<thead style="do some stuff to fix its position">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
</thead>
<tbody style="No scrolling allowed here!">
Data here
</tbody>
</table>
This approach has many issues such as ensures EXACT pixel widths because tables are so cute in that different browsers will allocate pixels differently based on calculations and you simply CANNOT (AFAIK) guarantee that the distribution will be perfect in all cases. It becomes glaringly obvious if you have borders within your table.
I took a different approach and said screw tables since you can't make this guarantee. I used divs to mimic tables. This also has issues of positioning the rows and columns (mainly because floating has issues, using in-line block won't work for IE7, so it really left me with using absolute positioning to put them in their proper places).
There is someone out there that made the Slick Grid which has a very similar approach to mine and you can use and a good (albeit complex) example for achieving this.
One way we do this in our application is using IDisposable and then with using(){}
blocks to ensure the cursor is reset when done.
public class OverrideCursor : IDisposable
{
public OverrideCursor(Cursor changeToCursor)
{
Mouse.OverrideCursor = changeToCursor;
}
#region IDisposable Members
public void Dispose()
{
Mouse.OverrideCursor = null;
}
#endregion
}
and then in your code:
using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
// Do work...
}
The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.
Update
To prevent the cursor flickering you can do:
public class OverrideCursor : IDisposable
{
static Stack<Cursor> s_Stack = new Stack<Cursor>();
public OverrideCursor(Cursor changeToCursor)
{
s_Stack.Push(changeToCursor);
if (Mouse.OverrideCursor != changeToCursor)
Mouse.OverrideCursor = changeToCursor;
}
public void Dispose()
{
s_Stack.Pop();
Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;
if (cursor != Mouse.OverrideCursor)
Mouse.OverrideCursor = cursor;
}
}
multipart/form-data
is used when you want to upload files to the server. Please check this article for details.
This should work:
SELECT field,CONVERT(SUBSTRING_INDEX(field,'-',-1),UNSIGNED INTEGER) AS num
FROM table
ORDER BY num;
Basic subsetting:
album2 <- album2[, -5] #delete column 5
album2 <- album2[, -c(5:7)] # delete columns 5 through 7
You can access multiple columns by passing a list of column indices to dataFrame.ix.
For example:
>>> df = pandas.DataFrame({
'a': np.random.rand(5),
'b': np.random.rand(5),
'c': np.random.rand(5),
'd': np.random.rand(5)
})
>>> df
a b c d

1 0.198005 0.520747 0.827818 0.366271
2 0.974552 0.667484 0.056246 0.524306
3 0.512126 0.775926 0.837896 0.955200
4 0.793203 0.686405 0.401596 0.544421
>>> df.ix[:,[1,3]]

0 0.414073 0.889579
1 0.520747 0.366271
2 0.667484 0.524306

See docs.python.org:
When you’re done with a file, call f.close() to close it and free up any system resources taken up by the open file. After calling f.close(), attempts to use the file object will automatically fail.
Hence use close()
elegantly with try/finally
:
f = open('file.txt', 'r')
try:
# do stuff with f
finally:
f.close()
This ensures that even if # do stuff with f
raises an exception, f
will still be closed properly.
Note that open
should appear outside of the try
. If open
itself raises an exception, the file wasn't opened and does not need to be closed. Also, if open
raises an exception its result is not assigned to f
and it is an error to call f.close()
.
Don't prematurely optimize. If you have no reason to believe there's a speed bottleneck caused by string concatenations then just stick with +
and +=
:
s = 'foo'
s += 'bar'
s += 'baz'
That said, if you're aiming for something like Java's StringBuilder, the canonical Python idiom is to add items to a list and then use str.join
to concatenate them all at the end:
l = []
l.append('foo')
l.append('bar')
l.append('baz')
s = ''.join(l)
if you already have that hidden input :
function product(a, b) {
return a * b;
}
function setInputValue(input_id, val) {
document.getElementById(input_id).setAttribute('value', val);
}
if not, you can create one, add it to the body and then set it's value :
function addInput(val) {
var input = document.createElement('input');
input.setAttribute('type', 'hidden');
input.setAttribute('value', val);
document.body.appendChild(input);
}
And then you can use(depending on the case) :
addInput(product(2, 3)); // if you want to create the input
// or
setInputValue('input_id', product(2, 3));
JavaScript version in case if jQuery is not an option.

Can't you originally get the data as a JSONObject?
Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?
I'm not sure that it is possible to convert a JsonArray into a JsonObject.
I presume you are using the following from json.org
JSONObject.java
A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
JSONArray.java
A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
[self dismissModalViewControllerAnimated:NO];
has been deprecated.
Use [self dismissViewControllerAnimated:NO completion:nil];
instead.
Anonymous types are just regular types that are implicitly declared. They have little to do with dynamic
.
Now, if you were to use an ExpandoObject and reference it through a dynamic
variable, you could add or remove fields on the fly.
edit
Sure you can: just cast it to IDictionary<string, object>
. Then you can use the indexer.
You use the same casting technique to iterate over the fields:
dynamic employee = new ExpandoObject();
employee.Name = "John Smith";
employee.Age = 33;
foreach (var property in (IDictionary<string, object>)employee)
{
Console.WriteLine(property.Key + ": " + property.Value);
}
// This code example produces the following output:
// Name: John Smith
// Age: 33

This basically has to do with the hardware architecture (i.e. RAM and caches).
If you don't use synchronized
together with wait()
or notify()
, another thread could enter the same block instead of waiting for the monitor to enter it. Moreover, when e.g. accessing an array without a synchronized block, another thread may not see the changement to it...actually another thread will not see any changements to it when it already has a copy of the array in the x-level cache (a.k.a. 1st/2nd/3rd-level caches) of the thread handling CPU core.
But synchronized blocks are only one side of the medal: If you actually access an object within a synchronized context from a non-synchronized context, the object still won't be synchronized even within a synchronized block, because it holds an own copy of the object in its cache. I wrote about this issues here: https://stackoverflow.com/a/21462631 and When a lock holds a non-final object, can the object's reference still be changed by another thread?
Furthermore, I'm convinced that the x-level caches are responsible for most non-reproducible runtime errors. That's because the developers usually don't learn the low-level stuff, like how CPU's work or how the memory hierarchy affects the running of applications: http://en.wikipedia.org/wiki/Memory_hierarchy
It remains a riddle why programming classes don't start with memory hierarchy and CPU architecture first. "Hello world" won't help here. ;)

Jon Skeet has written a library called morelinq which has a DistinctBy()
operator. See here for the implementation. Your code would look like
IEnumerable<Note> distinctNotes = Notes.DistinctBy(note => note.Author);
Update: After re-reading your question, Kirk has the correct answer if you're just looking for a distinct set of Authors.
Added sample, several fields in DistinctBy:
res = res.DistinctBy(i => i.Name).DistinctBy(i => i.ProductId).ToList();

OpenCode appears to be a project at the MIT Media Lab for running Java Code online in a web browser interface. Years ago, I played around a lot at TopCoder. It runs a Java Web Start app, though, so you would need a Java run time installed.
Just invert the indexes' order like this:
for (int j = 0; j<array[0].length; j++){
for (int i = 0; i<array.length; i++){
because all rows has same amount of columns you can use this condition j < array[0].lengt in first for condition due to the fact you are iterating over a matrix
Here is the answer:
Download the "Windows Mobile Device Center" for your machine type, likely 64bit.
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=3182
Before you run the install, change the compatibility settings to 'Windows 7'. Then install it... Then run it: You'll find it under 'WMDC'.. Your device should now recognize, when plugged in, mine did!
I'm quite surprised nobody mentioned the open-source project gogs (http://gogs.io) or a derived fork of it called gitea (http://gitea.io) which basically offers the same what gitlab does, but with minimal system resources (low footprint), being perfect to run in a Raspberry Pi for example. Installation and maintenance is also way simpler.
Have a look at the jQuery.scrollTo plugin. Here's a demo.
This plugin has a lot of options that go beyond what native scrollIntoView offers you. For instance, you can set the scrolling to be smooth, and then set a callback for when the scrolling finishes.
You can also have a look at all the JQuery plugins tagged with "scroll".
Whenever a record has updated a record is "deleted". Here is my example:
ALTER TRIGGER [dbo].[UpdatePhyDate]
ON [dbo].[M_ContractDT1]
AFTER UPDATE
AS
BEGIN
-- on ContarctDT1 PhyQty is updated
-- I want system date in Phytate automatically saved
SET NOCOUNT ON;
declare @dt1ky as int
if(update(Phyqty))
begin
select @dt1ky = dt1ky from deleted
update M_ContractDT1 set PhyDate=GETDATE() where Dt1Ky= @dt1ky
end
END
It works fine
You don't need an initializer, unless you're dynamically loading a different image each time. I think doing as much as possible in fxml is more organized. Here is an fxml file that will do what you need.
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<AnchorPane
xmlns:fx="http://javafx.co/fxml/1"
xmlns="http://javafx.com/javafx/2.2"
fx:controller="application.SampleController"
prefHeight="316.0"
prefWidth="321.0"
>
<children>
<ImageView
fx:id="imageView"
fitHeight="150.0"
fitWidth="200.0"
layoutX="61.0"
layoutY="83.0"
pickOnBounds="true"
preserveRatio="true"
>
<image>
<Image
url="src/Box13.jpg"
backgroundLoading="true"
/>
</image>
</ImageView>
</children>
</AnchorPane>
Specifying the backgroundLoading property in the Image tag is optional, it defaults to false. It's best to set backgroundLoading true when it takes a moment or longer to load the image, that way a placeholder will be used until the image loads, and the program wont freeze while loading.
if you are using linux on cloud, then usually you don't have chance to touch the real hardware using your hands. so you don't see the configuration interface when booting for the first time, and of course cannot configure it. As a result, the firstboot
service will always be in the way to rc.local
. The solution is to disable firstboot
by doing:
sudo chkconfig firstboot off
if you are not sure why your rc.local
does not run, you can always check from /etc/rc.d/rc
file because this file will always run and call other subsystems (e.g. rc.local).

Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions.
There is a bit of a learning curve but it is far and away the best tool available.
using XML, you need to set the onclick listener yourself. First have your class implements OnClickListener
then add the variable Button button1;
then add this to your onCreate()
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(this);
when you implement OnClickListener you need to add the inherited method onClick()
where you will handle your clicks

export class MyComponent {
// inject location into component constructor
constructor(private location: Location) { }
cancel() {
this.location.back(); // <-- go back to previous location on cancel
}
}
You need to write all the lines you read into the output file, even if you don't change them.
Something like:
using (var input = File.OpenText("input.txt"))
using (var output = new StreamWriter("output.txt")) {
string line;
while (null != (line = input.ReadLine())) {
// optionally modify line.
output.WriteLine(line);
}
}
If you want to perform this operation in place then the easiest way is to use a temporary output file and at the end replace the input file with the output.
File.Delete("input.txt");
File.Move("output.txt", "input.txt");
(Trying to perform update operations in the middle of text file is rather hard to get right because always having the replacement the same length is hard given most encodings are variable width.)
EDIT: Rather than two file operations to replace the original file, better to use File.Replace("input.txt", "output.txt", null)
. (See MSDN.)
Here's one from jQuery Validate plugin's additional-methods.js
file...
jQuery.validator.addMethod("zipUS", function(value, element) {
return /(^\d{5}$)|(^\d{5}-\d{4}$)/.test(value);
}, "Please specify a valid US zip code.");
EDIT: Since the above code is part of the jQuery Validate plugin, it depends on the .addMethod()
method.
Remove dependency on plugins and make it more generic....
function checkZip(value) {
return (/(^\d{5}$)|(^\d{5}-\d{4}$)/).test(value);
};

I can't tell if you've found some special case code which requires you to test against private fields. But in my experience you never have to test something private - always public. Maybe you could give an example of some code where you need to test private?
This instruction works fine:
Thread.currentThread().getStackTrace()[1].getClassName();
Try this,
<iframe id="testframe" src="about:blank" onload="if (testframe.location.href != 'about:blank') testframe_loaded()"></iframe>
All you need to do then is create the JavaScript function testframe_loaded().
pass your url in this method
private void startWebView(String url) {
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
progressDialog = new ProgressDialog(ContestActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
}
}
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(ContestActivity.this, "Error:" + description, Toast.LENGTH_SHORT).show();
}
});
webView.loadUrl(url);
}
An unhandled exception will (assuming it's repeatable like bad data as opposed to read errors from a particular data node) eventually fail the job anyway.
You can configure the maximum number of times a particular map or reduce task can fail before the entire job fails through the following properties:
mapred.map.max.attempts
- The maximum number of attempts per map task. In other words, framework will try to execute a map task these many number of times before giving up on it.mapred.reduce.max.attempts
- Same as above, but for reduce tasksIf you want to fail the job out at the first failure, set this value from its default of 4 to 1.
It can be done simply by using the following codes inside onCreate. By using android's default layout
Snackbar.make(findViewById(android.R.id.content),"Your Message",Snackbar.LENGTH_LONG).show();
this worked for me:
SELECT pg_catalog.setval('public.hibernate_sequence', 3, true);
Assuming these were datetime columns (if they're not apply to_datetime
) you can just subtract them:
df['A'] = pd.to_datetime(df['A'])
df['B'] = pd.to_datetime(df['B'])
In [11]: df.dtypes # if already datetime64 you don't need to use to_datetime
Out[11]:
A datetime64[ns]
B datetime64[ns]
dtype: object
In [12]: df['A'] - df['B']
Out[12]:
one -58 days
two -26 days
dtype: timedelta64[ns]
In [13]: df['C'] = df['A'] - df['B']
In [14]: df
Out[14]:
A B C
one 2014-01-01 2014-02-28 -58 days
two 2014-02-03 2014-03-01 -26 days
Note: ensure you're using a new of pandas (e.g. 0.13.1), this may not work in older versions.

Do it the hard way. Use the awesome MODEL
clause:
SELECT V
FROM DUAL
MODEL DIMENSION BY (0 R)
MEASURES (0 V)
RULES ITERATE (100) (
V[ITERATION_NUMBER] = ITERATION_NUMBER + 1
)
ORDER BY 1
Can you use:
unless @players.include?(p.name) do
...
end
unless
is opposite of if
, or you may use reject
.
You can reject
the not-required elements:
@players.reject{|x| x==p.name}
after the getting the results you can do your implementation.
This may not be a popular solution for everyone, but I like the Application Framework in Visual Basic, even when using C#.
Add a reference to Microsoft.VisualBasic
Create a class called WindowsFormsApplication
public class WindowsFormsApplication : WindowsFormsApplicationBase
{
/// <summary>
/// Runs the specified mainForm in this application context.
/// </summary>
/// <param name="mainForm">Form that is run.</param>
public virtual void Run(Form mainForm)
{
// set up the main form.
this.MainForm = mainForm;
// Example code
((Form1)mainForm).FileName = this.CommandLineArgs[0];
// then, run the the main form.
this.Run(this.CommandLineArgs);
}
/// <summary>
/// Runs this.MainForm in this application context. Converts the command
/// line arguments correctly for the base this.Run method.
/// </summary>
/// <param name="commandLineArgs">Command line collection.</param>
private void Run(ReadOnlyCollection<string> commandLineArgs)
{
// convert the Collection<string> to string[], so that it can be used
// in the Run method.
ArrayList list = new ArrayList(commandLineArgs);
string[] commandLine = (string[])list.ToArray(typeof(string));
this.Run(commandLine);
}
}
Modify your Main() routine to look like this
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var application = new WindowsFormsApplication();
application.Run(new Form1());
}
}
This method offers some additional usefull features (like SplashScreen support and some usefull events)
public event NetworkAvailableEventHandler NetworkAvailabilityChanged;d.
public event ShutdownEventHandler Shutdown;
public event StartupEventHandler Startup;
public event StartupNextInstanceEventHandler StartupNextInstance;
public event UnhandledExceptionEventHandler UnhandledException;
I tried to use the \x00 and it didn't work for me when using C# and Regex. I had success with the following:
//The hexidecimal 0x0 is the null character
mystring.Contains(Convert.ToChar(0x0).ToString() );
// This will replace the character
mystring = mystring.Replace(Convert.ToChar(0x0).ToString(), "");
Instant.now()
The troublesome old date-time classes bundled with the earliest versions of Java have been supplanted by the java.time classes built into Java 8 and later. See Oracle Tutorial. Much of the functionality has been back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.
Instant
An Instant
represents a moment on the timeline in UTC with a resolution of up to nanoseconds.
Instant instant = Instant.now();
The toString
method generates a String object with text representing the date-time value using one of the standard ISO 8601 formats.
String output = instant.toString();
2016-06-27T19:15:25.864Z
The Instant
class is a basic building-block class in java.time. This should be your go-to class when handling date-time as generally the best practice is to track, store, and exchange date-time values in UTC.
OffsetDateTime
But Instant
has limitations such as no formatting options for generating strings in alternate formats. For more flexibility, convert from Instant
to OffsetDateTime
. Specify an offset-from-UTC. In java.time that means a ZoneOffset
object. Here we want to stick with UTC (+00) so we can use the convenient constant ZoneOffset.UTC
.
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC );
2016-06-27T19:15:25.864Z
Or skip the Instant
class.
OffsetDateTime.now( ZoneOffset.UTC )
Now with an OffsetDateTime
object in hand, you can use DateTimeFormatter
to create String objects with text in alternate formats. Search Stack Overflow for many examples of using DateTimeFormatter
.
ZonedDateTime
When you want to display wall-clock time for some particular time zone, apply a ZoneId
to get a ZonedDateTime
.
In this example we apply Montréal time zone. In the summer, under Daylight Saving Time (DST) nonsense, the zone has an offset of -04:00
. So note how the time-of-day is four hours earlier in the output, 15
instead of 19
hours. Instant
and the ZonedDateTime
both represent the very same simultaneous moment, just viewed through two different lenses.
ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );
2016-06-27T15:15:25.864-04:00[America/Montreal]
While you should avoid the old date-time classes, if you must you can convert using new methods added to the old classes. Here we use java.util.Date.from( Instant )
and java.util.Date::toInstant
.
java.util.Date utilDate = java.util.Date.from( instant );
And going the other direction.
Instant instant= utilDate.toInstant();
Similarly, look for new methods added to GregorianCalendar
(subclass of Calendar
) to convert to and from java.time.ZonedDateTime
.
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes. Hibernate 5 & JPA 2.2 support java.time.

Update Table Set MyField = Nz(MyField,0)
The syntax of the class creation statement:
class <ClassName>(superclass):
#code follows
In the absence of any other superclasses that you specifically want to inherit from, the superclass
should always be object
, which is the root of all classes in Python.
object
is technically the root of "new-style" classes in Python. But the new-style classes today are as good as being the only style of classes.
But, if you don't explicitly use the word object
when creating classes, then as others mentioned, Python 3.x implicitly inherits from the object
superclass. But I guess explicit is always better than implicit (hell)
It sounds trivial, but my issue was that I wasn't in the right project. Make sure you are in the project you expect to be in; otherwise, you won't be able to pull down the correct branches.
Try this:
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class Main {
public static void main(String[] argv) throws Exception {
JTextField textField = new JTextField();
textField.addKeyListener(new Keychecker());
JFrame jframe = new JFrame();
jframe.add(textField);
jframe.setSize(400, 350);
jframe.setVisible(true);
}
class Keychecker extends KeyAdapter {
@Override
public void keyPressed(KeyEvent event) {
char ch = event.getKeyChar();
System.out.println(event.getKeyChar());
}
}
When you are using Google Chrome you can use/abuse the Google Filesystem API
for this. Here you can create a file with a specified name and write the content of a blob to it. Then you can return the result to the user.
I have not found a good way for Firefox yet; probably a small piece of Flash like downloadify
is required to name a blob.
IE10 has a msSaveBlob()
function in the BlobBuilder
.
Maybe this is more for downloading a blob, but it is related.
In Python, += is sugar coating for the __iadd__
special method, or __add__
or __radd__
if __iadd__
isn't present. The __iadd__
method of a class can do anything it wants. The list object implements it and uses it to iterate over an iterable object appending each element to itself in the same way that the list's extend method does.
Here's a simple custom class that implements the __iadd__
special method. You initialize the object with an int, then can use the += operator to add a number. I've added a print statement in __iadd__
to show that it gets called. Also, __iadd__
is expected to return an object, so I returned the addition of itself plus the other number which makes sense in this case.
>>> class Adder(object):
def __init__(self, num=0):
self.num = num
def __iadd__(self, other):
print 'in __iadd__', other
self.num = self.num + other
return self.num
>>> a = Adder(2)
>>> a += 3
in __iadd__ 3
>>> a
5
Hope this helps.

To solve incorrect SPNs with SQL Server I used this tool
