i want to post my solution here which was done AngularJS, ASP.NET MVC. The code illustrates how to download file with authentication.
WebApi method along with helper class:
[RoutePrefix("filess")]
class FileController: ApiController
{
[HttpGet]
[Route("download-file")]
[Authorize(Roles = "admin")]
public HttpResponseMessage DownloadDocument([FromUri] int fileId)
{
var file = "someFile.docx"// asking storage service to get file path with id
return Request.ReturnFile(file);
}
}
static class DownloadFIleFromServerHelper
{
public static HttpResponseMessage ReturnFile(this HttpRequestMessage request, string file)
{
var result = request.CreateResponse(HttpStatusCode.OK);
result.Content = new StreamContent(new FileStream(file, FileMode.Open, FileAccess.Read));
result.Content.Headers.Add("x-filename", Path.GetFileName(file)); // letters of header names will be lowercased anyway in JS.
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = Path.GetFileName(file)
};
return result;
}
}
Web.config file changes to allow sending file name in custom header.
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Methods" value="POST,GET,PUT,PATCH,DELETE,OPTIONS" />
<add name="Access-Control-Allow-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Expose-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Allow-Origin" value="*" />
Angular JS Service Part:
function proposalService($http, $cookies, config, FileSaver) {
return {
downloadDocument: downloadDocument
};
function downloadFile(documentId, errorCallback) {
$http({
url: config.apiUrl + "files/download-file?documentId=" + documentId,
method: "GET",
headers: {
"Content-type": "application/json; charset=utf-8",
"Authorization": "Bearer " + $cookies.get("api_key")
},
responseType: "arraybuffer"
})
.success( function(data, status, headers) {
var filename = headers()['x-filename'];
var blob = new Blob([data], { type: "application/octet-binary" });
FileSaver.saveAs(blob, filename);
})
.error(function(data, status) {
console.log("Request failed with status: " + status);
errorCallback(data, status);
});
};
};
Module dependency for FileUpload: angular-file-download (gulp install angular-file-download --save). Registration looks like below.
var app = angular.module('cool',
[
...
require('angular-file-saver'),
])
. // other staff.
use:
std::vector <Acard> playerHand;
everywhere qualify it by std::
or do:
using std::vector;
in your cpp file.
You have to do this because vector
is defined in the std
namespace and you do not tell your program to find it in std
namespace, you need to tell that.
Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:
*** Phones:
*** Tablets:
Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.
function decodeHTMLContent(htmlText) {
var txt = document.createElement("span");
txt.innerHTML = htmlText;
return txt.innerText;
}
var result = decodeHTMLContent('One & two & three');
console.log(result);

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}
Just change MAIL_ENCRYPTION=null to MAIL_ENCRYPTION=tls
And run this command "php artisan config:cache"
This generally indicates MySQL server connectivity issues or timeouts. Can generally be solved by changing wait_timeout and max_allowed_packet in my.cnf or similar.
I would suggest these values:
wait_timeout = 28800
max_allowed_packet = 8M
Pure js. Can apply it to multiple tables at once. Aborts if only one page is required. I used anushree as my starting point.
Sorry to the asker, obviously this is not a simplePagignation.js solution. However, it's the top google result when you type "javascript table paging", and it's a reasonable solution to many who may be considering a library but unsure whether to go that route or not.
Use like this:
addPagerToTables('#someTable', 8);
Requires no css, though it may be wise to initially hide table tBody rows in css anyway to prevent the effect of rows showing then quicky being hidden (not happening with me right now, but it's something I've seen before).
The code:
function addPagerToTables(tables, rowsPerPage = 10) {
tables =
typeof tables == "string"
? document.querySelectorAll(tables)
: tables;
for (let table of tables)
addPagerToTable(table, rowsPerPage);
}
function addPagerToTable(table, rowsPerPage = 10) {
let tBodyRows = table.querySelectorAll('tBody tr');
let numPages = Math.ceil(tBodyRows.length/rowsPerPage);
let colCount =
[].slice.call(
table.querySelector('tr').cells
)
.reduce((a,b) => a + parseInt(b.colSpan), 0);
table
.createTFoot()
.insertRow()
.innerHTML = `<td colspan=${colCount}><div class="nav"></div></td>`;
if(numPages == 1)
return;
for(i = 0;i < numPages;i++) {
let pageNum = i + 1;
table.querySelector('.nav')
.insertAdjacentHTML(
'beforeend',
`<a href="#" rel="${i}">${pageNum}</a> `
);
}
changeToPage(table, 1, rowsPerPage);
for (let navA of table.querySelectorAll('.nav a'))
navA.addEventListener(
'click',
e => changeToPage(
table,
parseInt(e.target.innerHTML),
rowsPerPage
)
);
}
function changeToPage(table, page, rowsPerPage) {
let startItem = (page - 1) * rowsPerPage;
let endItem = startItem + rowsPerPage;
let navAs = table.querySelectorAll('.nav a');
let tBodyRows = table.querySelectorAll('tBody tr');
for (let nix = 0; nix < navAs.length; nix++) {
if (nix == page - 1)
navAs[nix].classList.add('active');
else
navAs[nix].classList.remove('active');
for (let trix = 0; trix < tBodyRows.length; trix++)
tBodyRows[trix].style.display =
(trix >= startItem && trix < endItem)
? 'table-row'
: 'none';
}
}
As you've discovered, you can't do that. You can do:
libtest_LIBS =
...
if HAVE_CLIENT
libtest_LIBS += libclient.la
endif
if HAVE_SERVER
libtest_LIBS += libserver.la
endif
I believe you can do this using a cast:
float f_val = 3.6f;
int i_val = (int) f_val;
In my case my problem was that I was using an older version of NetBeans. The Maven repository removed an http reference, but the embedded Maven in Netbeans had that http reference hard-coded. I was really confused at first because my pom.xml referenced the proper https://repo.maven.apache.org/maven2.
Fixing it was pretty simple. I downloaded the latest zip archive of Maven from the following location and extracted it to my machine: https://maven.apache.org/download.cgi
Within Netbeans at Tools -> Options -> Java -> Maven on the "Execution" section I set "Maven Home" to the newly extracted zip file location.
Now I could build my project....
On Unix you can use valgrind
to find issues. It's free and powerful. If you'd rather do it yourself you can overload the new
and delete
operators to set up a configuration where you have 1 byte with 0xDEADBEEF
before and after each new object. Then track what happens at each iteration. This can fail to catch everything (you aren't guaranteed to even touch those bytes) but it has worked for me in the past on a Windows platform.
Here is what I ended up doing and it worked great.
First I moved the file input outside of the form so that it is not submitted:
<input name="imagefile[]" type="file" id="takePictureField" accept="image/*" onchange="uploadPhotos(\'#{imageUploadUrl}\')" />
<form id="uploadImageForm" enctype="multipart/form-data">
<input id="name" value="#{name}" />
... a few more inputs ...
</form>
Then I changed the uploadPhotos
function to handle only the resizing:
window.uploadPhotos = function(url){
// Read in file
var file = event.target.files[0];
// Ensure it's an image
if(file.type.match(/image.*/)) {
console.log('An image has been loaded');
// Load the image
var reader = new FileReader();
reader.onload = function (readerEvent) {
var image = new Image();
image.onload = function (imageEvent) {
// Resize the image
var canvas = document.createElement('canvas'),
max_size = 544,// TODO : pull max size from a site config
width = image.width,
height = image.height;
if (width > height) {
if (width > max_size) {
height *= max_size / width;
width = max_size;
}
} else {
if (height > max_size) {
width *= max_size / height;
height = max_size;
}
}
canvas.width = width;
canvas.height = height;
canvas.getContext('2d').drawImage(image, 0, 0, width, height);
var dataUrl = canvas.toDataURL('image/jpeg');
var resizedImage = dataURLToBlob(dataUrl);
$.event.trigger({
type: "imageResized",
blob: resizedImage,
url: dataUrl
});
}
image.src = readerEvent.target.result;
}
reader.readAsDataURL(file);
}
};
As you can see I'm using canvas.toDataURL('image/jpeg');
to change the resized image into a dataUrl adn then I call the function dataURLToBlob(dataUrl);
to turn the dataUrl into a blob that I can then append to the form. When the blob is created, I trigger a custom event. Here is the function to create the blob:
/* Utility function to convert a canvas to a BLOB */
var dataURLToBlob = function(dataURL) {
var BASE64_MARKER = ';base64,';
if (dataURL.indexOf(BASE64_MARKER) == -1) {
var parts = dataURL.split(',');
var contentType = parts[0].split(':')[1];
var raw = parts[1];
return new Blob([raw], {type: contentType});
}
var parts = dataURL.split(BASE64_MARKER);
var contentType = parts[0].split(':')[1];
var raw = window.atob(parts[1]);
var rawLength = raw.length;
var uInt8Array = new Uint8Array(rawLength);
for (var i = 0; i < rawLength; ++i) {
uInt8Array[i] = raw.charCodeAt(i);
}
return new Blob([uInt8Array], {type: contentType});
}
/* End Utility function to convert a canvas to a BLOB */
Finally, here is my event handler that takes the blob from the custom event, appends the form and then submits it.
/* Handle image resized events */
$(document).on("imageResized", function (event) {
var data = new FormData($("form[id*='uploadImageForm']")[0]);
if (event.blob && event.url) {
data.append('image_data', event.blob);
$.ajax({
url: event.url,
data: data,
cache: false,
contentType: false,
processData: false,
type: 'POST',
success: function(data){
//handle errors...
}
});
}
});
Doing a relative import is absolulutely OK! Here's what little 'ol me does:
#first change the cwd to the script path
scriptPath = os.path.realpath(os.path.dirname(sys.argv[0]))
os.chdir(scriptPath)
#append the relative location you want to import from
sys.path.append("../common")
#import your module stored in '../common'
import common.py
I tried the example that you have provided and the only difference is that you have True and False values switched as @bdparrish
had pointed out. Here is a working example of making an SSRS Texbox visible or hidden based on the number of rows present in a dataset. This example uses SSRS 2008 R2
.
Step-by-step process: SSRS 2008 R2
In this example, the report has a dataset named Items
and has textbox to show row counts. It also has another textbox which will be visible only if the dataset Items has rows.
Right-click on the textbox that should be visible/hidden based on an expression and select Text Box Properties...
. Refer screenshot #1.
On the Text Box Properties
dialog, click on Visibility
from the left section. Refer screenshot #2.
Select Show or hide based on an epxression
.
Click on the expression button fx
.
Enter the expression =IIf(CountRows("Items") = 0 , True, False)
. Note that this expression is to hide the Textbox (Hidden).
Click OK twice to close the dialogs.
Screenshot #3 shows data in the SQL Server table dbo.Items
, which is the source for the report data set Items
. The table contains 3 rows. Screenshot #4 shows the sample report execution against the data.
Screenshot #5 shows data in the SQL Server table dbo.Items
, which is the source for the report data set Items
. The table contains no data. Screenshot #6 shows the sample report execution against the data.
Hope that helps.

You can do this all in the File.open block:
Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
playlist_name = gets.chomp + '.m3u'
File.open playlist_name, 'w' do |f|
music.each do |z|
f.puts z
end
end
Another options is Matteo Bicocchi's jQuery mb.extruder tabs plug-in: http://pupunzi.open-lab.com/mb-jquery-components/jquery-mb-extruder/
If you want a big database of real data to play with, you could sign up for the Netflix Prize contest and get access to their data, which is pretty large (a few gigs of entries).
The URL above does not contain the dataset anylonger (october 2016). The wikipedia page about the Netflix Prize reports that a law suit was settled regarding privacy concerns.
You can call setScale(newScale, roundingMode)
method three times with changing the newScale value from 4 to 3 to 2 like
First case
BigDecimal a = new BigDecimal("10.12345");
a = a.setScale(4, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.1235
a = a.setScale(3, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.124
a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.12
Second case
BigDecimal a = new BigDecimal("10.12556");
a = a.setScale(4, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.1256
a = a.setScale(3, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.126
a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("" + a); //10.13
Update your Eclipse ADT Plugin to 22.0 or higher, then go to File | Export
Go to Android now then click on Generate Gradle build files
, then it would generate gradle file for you.
Select your project you want to export
Click on finish now
In Android Studio, close any projects currently open. You should see the Welcome to Android Studio window.
Click Import Project.
Locate the project you exported from Eclipse, expand it, select it and click OK.
This is a highly inefficient way of doing it. You can use the merge
statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.
MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
UPDATE SET l.studName = s.studName
WHERE l.studName != s.studName
WHEN NOT MATCHED THEN
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)
Make sure you commit
, once completed, in order to be able to see this in the database.
To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.
It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.
However, as I say this will not be as efficient as merge
.
declare
cursor c_data is
select b.rowid as rid, a.studId, a.studName
from student a
left outer join studLoad b
on a.studId = b.studId
and a.studName <> b.studName
;
type t__data is table of c_data%rowtype index by binary_integer;
t_data t__data;
begin
open c_data;
loop
fetch c_data bulk collect into t_data limit 10000;
exit when t_data.count = 0;
for idx in t_data.first .. t_data.last loop
if t_data(idx).rid is null then
insert into studLoad (studId, studName)
values (t_data(idx).studId, t_data(idx).studName);
else
update studLoad
set studName = t_data(idx).studName
where rowid = t_data(idx).rid
;
end if;
end loop;
end loop;
close c_data;
end;

Since bash
5.0 (released on 7 Jan 2019) you can use the built-in variable EPOCHSECONDS
.
$ echo $EPOCHSECONDS
1547624774
There is also EPOCHREALTIME
which includes fractions of seconds.
$ echo $EPOCHREALTIME
1547624774.371215
EPOCHREALTIME
can be converted to micro-seconds (µs) by removing the decimal point. This might be of interest when using bash
's built-in arithmetic (( expression ))
which can only handle integers.
$ echo ${EPOCHREALTIME/./}
1547624774371215
In all examples from above the printed time values are equal for better readability. In reality the time values would differ since each command takes a small amount of time to be executed.
If you don't want to change your default settings, and you only want to change the width of the current notebook you're working on, you can enter the following into a cell:
from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))
The Multipart File Upload worked after following code modification to Upload using RestTemplate
LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new ClassPathResource(file));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new HttpEntity<LinkedMultiValueMap<String, Object>>(
map, headers);
ResponseEntity<String> result = template.get().exchange(
contextPath.get() + path, HttpMethod.POST, requestEntity,
String.class);
And adding MultipartFilter to web.xml
<filter>
<filter-name>multipartFilter</filter-name>
<filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>multipartFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Functional Interfaces: An interface is called a functional interface if it has a single abstract method irrespective of the number of default or static methods. Functional Interface are use for lamda expression. Runnable
, Callable
, Comparable
, Comparator
are few examples of Functional
Interface.
KeyNotes:
@FunctionalInterface
is used(Optional).@FunctionalInterface
annotation is
used).This thread talks more in detail about what benefit functional Interface gives over anonymous class and how to use them.
Have you tried using JsonSlurper?
Example usage:
def slurper = new JsonSlurper()
def result = slurper.parseText('{"person":{"name":"Guillaume","age":33,"pets":["dog","cat"]}}')
assert result.person.name == "Guillaume"
assert result.person.age == 33
assert result.person.pets.size() == 2
assert result.person.pets[0] == "dog"
assert result.person.pets[1] == "cat"
Nothing helps me but this:
transparent_drawable.xml
:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#00000000"/>
</shape>
layout.xml
:
android:listSelector="@drawable/transparent_drawable"
-> is for pointers to a class instance
. is for class instances
:: is for classnames - for example when using a static member
And you can also set a different backup extension and where to save those backup (I prefer ~/.vimbackups
on linux). I used to use "versioned" backups, via:
au BufWritePre * let &bex = '-' . strftime("%Y%m%d-%H%M%S") . '.vimbackup'
This sets a dynamic backup extension (ORIGINALFILENAME-YYYYMMDD-HHMMSS.vimbackup
).
As of current edited version of the post, you call setInterval
at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.
You only need to "prime" setInterval
once. Remove it from function and place it inside onload
instead of direct function call.
Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:
var mvar = "";
$(".mbox").each(function() {
console.log($(this).html());
mvar += $(this).html();
});
console.log(mvar);
Most of the answers provided here address the number of incoming requests to your backend webservice, not the number of outgoing requests you can make from your ASP.net application to your backend service.
It's not your backend webservice that is throttling your request rate here, it is the number of open connections your calling application is willing to establish to the same endpoint (same URL).
You can remove this limitation by adding the following configuration section to your machine.config file:
<configuration>
<system.net>
<connectionManagement>
<add address="*" maxconnection="65535"/>
</connectionManagement>
</system.net>
</configuration>
You could of course pick a more reasonable number if you'd like such as 50 or 100 concurrent connections. But the above will open it right up to max. You can also specify a specific address for the open limit rule above rather than the '*' which indicates all addresses.
MSDN Documentation for System.Net.connectionManagement
Another Great Resource for understanding ConnectManagement in .NET
Hope this solves your problem!
EDIT: Oops, I do see you have the connection management mentioned in your code above. I will leave my above info as it is relevant for future enquirers with the same problem. However, please note there are currently 4 different machine.config files on most up to date servers!
There is .NET Framework v2 running under both 32-bit and 64-bit as well as .NET Framework v4 also running under both 32-bit and 64-bit. Depending on your chosen settings for your application pool you could be using any one of these 4 different machine.config files! Please check all 4 machine.config files typically located here:
The method Socket.Available will immediately throw a SocketException if the remote system has disconnected/closed the connection.
You can also use regular expressions (less readable though)
string regex = "^.{0,7}abc";
System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(regex);
string Value1 = "sssddabcgghh";
Console.WriteLine(reg.Match(Value1).Success);
My way:
private static int hexToDec(String hex) {
return Integer.parseInt(hex, 16);
}
Try this one, and then import the package:
import org.openqa.selenium.Keys;
driver.findElement(By.xpath("//*[@id='username']")).sendKeys("username");
driver.findElement(By.xpath("//*[@id='username']")).sendKeys(Keys.TAB);
driver.findElement(By.xpath("//*[@id='Password']")).sendKeys("password");
Your jQuery code works perfectly. The hidden field is being updated.
Even though utf8_decode
is a useful solution, I prefer to correct the encoding errors on the table itself. In my opinion it is better to correct the bad characters themselves than making "hacks" in the code. Simply do a replace
on the field on the table. To correct the bad encoded characters from OP :
update <table> set <field> = replace(<field>, "ë", "ë")
update <table> set <field> = replace(<field>, "Ã", "à")
update <table> set <field> = replace(<field>, "ì", "ì")
update <table> set <field> = replace(<field>, "ù", "ù")
Where <table>
is the name of the mysql table and <field>
is the name of the column in the table. Here is a very good check-list for those typically bad encoded windows-1252 to utf-8 characters -> Debugging Chart Mapping Windows-1252 Characters to UTF-8 Bytes to Latin-1 Characters.
Remember to backup your table before trying to replace any characters with SQL!
[I know this is an answer to a very old question, but was facing the issue once again. Some old windows machine didnt encoded the text correct before inserting it to the utf8_general_ci collated table.]
You should also take a look at svgweb. It uses flash to render svg in IE, and optionally on other browsers (in the cases where it supports more than the browser itself does).

Here an answer for those who'd like to have preinitialized lists of lists. Needs Java 8+.
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.IntStream;
class Scratch {
public static void main(String[] args) {
int M = 4;
int N = 3;
// preinitialized array (== list of lists) of strings, sizes not fixed
List<List<String>> listOfListsOfString = initializeListOfListsOfT(M, N, "-");
System.out.println(listOfListsOfString);
// preinitialized array (== list of lists) of int (primitive type), sizes not fixed
List<List<Integer>> listOfListsOfInt = initializeListOfListsOfInt(M, N, 7);
System.out.println(listOfListsOfInt);
}
public static <T> List<List<T>> initializeListOfListsOfT(int m, int n, T initValue) {
return IntStream
.range(0, m)
.boxed()
.map(i -> new ArrayList<T>(IntStream
.range(0, n)
.boxed()
.map(j -> initValue)
.collect(Collectors.toList()))
)
.collect(Collectors.toList());
}
public static List<List<Integer>> initializeListOfListsOfInt(int m, int n, int initValue) {
return IntStream
.range(0, m)
.boxed()
.map(i -> new ArrayList<>(IntStream
.range(0, n)
.map(j -> initValue)
.boxed()
.collect(Collectors.toList()))
)
.collect(Collectors.toList());
}
}
Output:
[[-, -, -], [-, -, -], [-, -, -], [-, -, -]]
[[7, 7, 7], [7, 7, 7], [7, 7, 7], [7, 7, 7]]
Side note for those wondering about IntStream
:
IntStream
.range(0, m)
.boxed()
is equivalent to
Stream

I am not 100% certain, but I think this does what you want using prop.table. See mostly the last 3 lines. The rest of the code is just creating fake data.
set.seed(1234)
total_bill <- rnorm(50, 25, 3)
tip <- 0.15 * total_bill + rnorm(50, 0, 1)
sex <- rbinom(50, 1, 0.5)
smoker <- rbinom(50, 1, 0.3)
day <- ceiling(runif(50, 0,7))
time <- ceiling(runif(50, 0,3))
size <- 1 + rpois(50, 2)
my.data <- as.data.frame(cbind(total_bill, tip, sex, smoker, day, time, size))
my.data
my.table <- table(my.data$smoker)
my.prop <- prop.table(my.table)
cbind(my.table, my.prop)
The first of option you tried doesn't work for two reasons.
First, you forgot to close the parenthesis.
Second, the DESTINATION
should be a directory, not a file name. Assuming that you closed the parenthesis, the file would end up in a folder called input.txt
.
To make it work, just change it to
file(COPY ${CMAKE_CURRENT_SOURCE_DIR}/input.txt
DESTINATION ${CMAKE_CURRENT_BINARY_DIR})

MD5 processes an arbitrary-length message into a fixed-length output of 128 bits, typically represented as a sequence of 32 hexadecimal digits.
In my case, I have to get 2 values what are objects. I share this simple solution.
$ran = array("a","b","c","d");
$ranval = array_map(function($i) use($ran){return $ran[$i];},array_rand($ran,2));
IF your input is String then I recommend you to store the String into a double and then convert the double to the long.
String str = "123.45";
Double a = Double.parseDouble(str);
long b = Math.round(a);
Ubuntu 12.04 this works...
JAVA_HOME=/usr/lib/jvm/java-6-openjdk-i386/jre
This will work for most of the website names :

temp = bankAccNos.contains(no) ? 1 : 2;
You may immediately invoke an anonymous async function that returns message and set it to the message variable. You might want to take a look at immediately invoked function expressions (IEFES), in case you are unfamiliar with this pattern. This will work like a charm.
var message = (async function() { return await grabUID(uid) })()
Follow these steps:
1) Install:

As Jose answered, screen -d -r
should do the trick. This is a combination of two commands, as taken from the man page.
screen -d
detaches the already-running screen session, and screen -r
reattaches the existing session. By running screen -d -r
, you force screen to detach it and then resume the session.
If you use the capital -D -RR
, I quote the man page because it's too good to pass up.
Attach here and now. Whatever that means, just do it.
Note: It is always a good idea to check the status of your sessions by means of "screen -list".
As you become more experienced with using Perl, you'll find that there are fewer and fewer occasions when you need to run shell commands. For example, one way to get a list of files is to use Perl's built-in glob function. If you want the list in sorted order you could combine it with the built-in sort function. If you want details about each file, you can use the stat function. Here's an example:
#!/usr/bin/perl
use strict;
use warnings;
foreach my $file ( sort glob('/home/grant/*') ) {
my($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks)
= stat($file);
printf("%-40s %8u bytes\n", $file, $size);
}
To kill from the application, you can do:
android.os.Process.killProcess(android.os.Process.myPid());
a="abc"
b="def"
# Equality Comparison
if [ "$a" == "$b" ]; then
echo "Strings match"
else
echo "Strings don't match"
fi
# Lexicographic (greater than, less than) comparison.
if [ "$a" \< "$b" ]; then
echo "$a is lexicographically smaller then $b"
elif [ "$a" \> "$b" ]; then
echo "$b is lexicographically smaller than $a"
else
echo "Strings are equal"
fi
Notes:
if
and [
and ]
are important>
and <
are redirection operators so escape it with \>
and \<
respectively for strings.A way to use this in react:
class Timeout extends Component {
constructor(props){
super(props)
this.state = {
timeout: null
}
}
userTimeout(){
const { timeout } = this.state;
clearTimeout(timeout);
this.setState({
timeout: setTimeout(() => {this.callAPI()}, 250)
})
}
}
Helpful if you'd like to only call an API after the user has stopped typing for instance. The userTimeout function could be bound via onKeyUp to an input.
If you are developing a command line application, you can also use Console.ReadLine()
at the end of your code to wait for the 'Enter' keypress before closing the console window so that you can read your output. However, both the Trace and Debug answers posted above are better options.
For those looking to add an item to a json collection
function save(item, path = './collection.json'){
if (!fs.existsSync(path)) {
fs.writeFile(path, JSON.stringify([item]));
} else {
var data = fs.readFileSync(path, 'utf8');
var list = (data.length) ? JSON.parse(data): [];
if (list instanceof Array) list.push(item)
else list = [item]
fs.writeFileSync(path, JSON.stringify(list));
}
}
For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str
to int
) so you must do this yourself. You'll like that in the long-run, trust me!
PDO class replaces these methods. Example for Mysql or MariaDB :
$BDD_SQL = new PDO('mysql:host='.BDD_SQL_SERVER.';dbname='.BDD_SQL_BASE.';charset=utf8',
BDD_SQL_LOGIN, BDD_SQL_PWD,
array(
PDO::ATTR_EMULATE_PREPARES => false,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, //launch exception if error
PDO::ATTR_DEFAULT_FETCH_MODE=> PDO::FETCH_ASSOC
));
Source : PDO Class
The formal (and perhaps old) way is Array.prototype.forEach(...)
:
var arr = ["apple", "banana", "cherry", "mango"];
arr.forEach(function(item, index, _) {
console.log("[" + index + "] = '" + item + "'");
});
df[df['Value']==df['Value'].max()]
This will return the entire row with max value
Shouldn't creating a new Runnable class make a new second thread?
No. new Runnable
does not create second Thread
.
What is the purpose of the Runnable class here apart from being able to pass a Runnable class to postAtTime?
Runnable
is posted to Handler
. This task runs in the thread, which is associated with Handler
.
If Handler
is associated with UI Thread, Runnable
runs in UI Thread.
If Handler
is associated with other HandlerThread
, Runnable runs in HandlerThread
To explicitly associate Handler to your MainThread ( UI Thread), write below code.
Handler mHandler = new Handler(Looper.getMainLooper();
If you write is as below, it uses HandlerThread Looper.
HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());
These paradigms don't have to be mutually exclusive. If you look at python, it supports functions and classes, but at the same time, everything is an object, including functions. You can mix and match functional/oop/procedural style all in one piece of code.
What I mean is, in functional languages (at least in Haskell, the only one I studied) there are no statements! functions are only allowed one expression inside them!! BUT, functions are first-class citizens, you can pass them around as parameters, along with a bunch of other abilities. They can do powerful things with few lines of code.
While in a procedural language like C, the only way you can pass functions around is by using function pointers, and that alone doesn't enable many powerful tasks.
In python, a function is a first-class citizen, but it can contain arbitrary number of statements. So you can have a function that contains procedural code, but you can pass it around just like functional languages.
Same goes for OOP. A language like Java doesn't allow you to write procedures/functions outside of a class. The only way to pass a function around is to wrap it in an object that implements that function, and then pass that object around.
In Python, you don't have this restriction.
This is how I count TABLES and ALL RECORDS using PHP:
$dtb = mysql_query("SHOW TABLES") or die (mysql_error());
$jmltbl = 0;
$jml_record = 0;
$jml_record = 0;
while ($row = mysql_fetch_array($dtb)) {
$sql1 = mysql_query("SELECT * FROM " . $row[0]);
$jml_record = mysql_num_rows($sql1);
echo "Table: " . $row[0] . ": " . $jml_record record . "<br>";
$jmltbl++;
$jml_record += $jml_record;
}
echo "--------------------------------<br>$jmltbl Tables, $jml_record > records.";
You just said javascript in your tags, so @Wampie Driessen post could helps you.
I want also to contribute, so you can use the following when using jQuery if you need it.
//Firefox
$('#elem').bind('DOMMouseScroll', function(e){
if(e.detail > 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
//IE, Opera, Safari
$('#elem').bind('mousewheel', function(e){
if(e.wheelDelta< 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
Another example:
$(function(){
var _top = $(window).scrollTop();
var _direction;
$(window).scroll(function(){
var _cur_top = $(window).scrollTop();
if(_top < _cur_top)
{
_direction = 'down';
}
else
{
_direction = 'up';
}
_top = _cur_top;
console.log(_direction);
});
});?
You may not need to use Pandas at all. Here's a matplotlib plot of cat frequencies:
x = np.linspace(0, 2*np.pi, 400)
y = np.sin(x**2)
f, axes = plt.subplots(2, 1)
for c, i in enumerate(axes):
axes[c].plot(x, y)
axes[c].set_title('cats')
plt.tight_layout()
If you are using Git Extensions: go into the Commit screen, there should be a checkbox that says "Amend Commit" at the bottom, as can be seen below:
If you know the width of the span you could just stuff in a left margin.
Try this:
.center { text-align: center}
div.center span { display: table; }
Add the "center: class to your .
If you want some spans centered, but not others, replace the "div.center span" in your style sheet to a class (e.g "center-span") and add that class to the span.
int x = 1;
System.out.format("%05d",x);
if you want to print the formatted text directly onto the screen.
I would suggest Jetbrain's IDE: DataGrip https://www.jetbrains.com/datagrip/
It works like this:
<ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Disabled" Width="340" HorizontalAlignment="Left" Margin="12,0,0,0">
<StackPanel Name="stackPanel1" Width="311">
</StackPanel>
</ScrollViewer>
TextBox tb = new TextBox();
tb.TextChanged += new TextChangedEventHandler(TextBox_TextChanged);
stackPanel1.Children.Add(tb);
The problem is with -3.7(prof[x])
, which looks like a function call (note the parens). Just use a *
like this -3.7*prof[x]
.

Use "REPLACE" to remove special characters.
REPLACE(ColumnName ,' " ','')
Ex: -
--Query ---
DECLARE @STRING AS VARCHAR(100)
SET @STRING ='VI''RA""NJA "'
SELECT @STRING
SELECT REPLACE(REPLACE(@STRING,'''',''),'"','') AS MY_NAME
--Result---
VI'RA""NJA"
The solution proposed here worked for me:
Intent i = new Intent(OldActivity.this, NewActivity.class);
// set the new task and clear flags
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i);
val i = Intent(this, NewActivity::class.java)
// set the new task and clear flags
i.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
startActivity(i)
However, it requires API level >= 11.
The \du

But that postgres=# \password postgres@implicit_files

Also after sudo -u postgres createuser -s postgres
the first variant also work.
Listview derives from listbox control. One most important difference is listview uses the extended selection mode by default . listview also adds a property called view which enables you to customize the view in a richer way than a custom itemspanel. One real life example of listview with gridview is file explorer's details view. Listview with grid view is a less powerful data grid. After the introduction of datagrid control listview lost its importance.

To get current host name :-
select @@hostname;
show variables where Variable_name like '%host%';
To get hosts for all incoming requests :-
select host from information_schema.processlist;
Based on your last comment,
I don't think you can resolve IP for the hostname using pure mysql function,
as it require a network lookup, which could be taking long time.
However, mysql document mention this :-
resolveip google.com.sg

The And
operator will check all conditions in the statement before continuing, whereas the Andalso operator will stop if it knows the condition is false. For example:
if x = 5 And y = 7
Checks if x is equal to 5, and if y is equal to 7, then continues if both are true.
if x = 5 AndAlso y = 7
Checks if x is equal to 5. If it's not, it doesn't check if y is 7, because it knows that the condition is false already. (This is called short-circuiting.)
Generally people use the short-circuiting method if there's a reason to explicitly not check the second part if the first part is not true, such as if it would throw an exception if checked. For example:
If Not Object Is Nothing AndAlso Object.Load()
If that used And
instead of AndAlso
, it would still try to Object.Load()
even if it were nothing
, which would throw an exception.
If you didn't add pip when creating conda environment
conda create -n env_name pip
and also didn't install pip inside the environment
source activate env_name
conda install pip
then the only pip you got is the system pip, which will install packages globally.
Bus as you can see in this issue, even if you did either of the procedure mentioned above, the behavior of pip inside conda environment is still kind of undefined.
To ensure using the pip installed inside conda environment without having to type the lengthy /home/username/anaconda/envs/env_name/bin/pip
, I wrote a shell function:
# Using pip to install packages inside conda environments.
cpip() {
ERROR_MSG="Not in a conda environment."
ERROR_MSG="$ERROR_MSG\nUse \`source activate ENV\`"
ERROR_MSG="$ERROR_MSG to enter a conda environment."
[ -z "$CONDA_DEFAULT_ENV" ] && echo "$ERROR_MSG" && return 1
ERROR_MSG='Pip not installed in current conda environment.'
ERROR_MSG="$ERROR_MSG\nUse \`conda install pip\`"
ERROR_MSG="$ERROR_MSG to install pip in current conda environment."
[ -e "$CONDA_PREFIX/bin/pip" ] || (echo "$ERROR_MSG" && return 2)
PIP="$CONDA_PREFIX/bin/pip"
"$PIP" "$@"
}
Hope this is helpful to you.
In SQL 2005 and above, there's a trick to solve this problem without changing the table's data pages. This is important for large tables where touching every data page can take minutes or hours. The trick also works even if the identity column is a primary key, is part of a clustered or non-clustered index, or other gotchas which can trip up the the simpler "add/remove/rename column" solution.
Here's the trick: you can use SQL Server's ALTER TABLE...SWITCH statement to change the schema of a table without changing the data, meaning you can replace a table with an IDENTITY with an identical table schema, but without an IDENTITY column. The same trick works to add IDENTITY to an existing column.
Normally, ALTER TABLE...SWITCH is used to efficiently replace a full partition in a partitioned table with a new, empty partition. But it can also be used in non-partitioned tables too.
I've used this trick to convert, in under 5 seconds, a column of a of a 2.5 billion row table from IDENTITY to a non-IDENTITY (in order to run a multi-hour query whose query plan worked better for non-IDENTITY columns), and then restored the IDENTITY setting, again in less than 5 seconds.
Here's a code sample of how it works.
CREATE TABLE Test
(
id int identity(1,1),
somecolumn varchar(10)
);
INSERT INTO Test VALUES ('Hello');
INSERT INTO Test VALUES ('World');
-- copy the table. use same schema, but no identity
CREATE TABLE Test2
(
id int NOT NULL,
somecolumn varchar(10)
);
ALTER TABLE Test SWITCH TO Test2;
-- drop the original (now empty) table
DROP TABLE Test;
-- rename new table to old table's name
EXEC sp_rename 'Test2','Test';
-- update the identity seed
DBCC CHECKIDENT('Test');
-- see same records
SELECT * FROM Test;
This is obviously more involved than the solutions in other answers, but if your table is large this can be a real life-saver. There are some caveats:
There's a good article on TechNet detailing the requirements above.
UPDATE - Eric Wu had a comment below that adds important info about this solution. Copying it here to make sure it gets more attention:
There's another caveat here that is worth mentioning. Although the new table will happily receive data from the old table, and all the new rows will be inserted following a identity pattern, they will start at 1 and potentially break if the said column is a primary key. Consider running
DBCC CHECKIDENT('<newTableName>')
immediately after switching. See msdn.microsoft.com/en-us/library/ms176057.aspx for more info.
If the table is actively being extended with new rows (meaning you don't have much if any downtime between adding IDENTITY and adding new rows, then instead of DBCC CHECKIDENT
you'll want to manually set the identity seed value in the new table schema to be larger than the largest existing ID in the table, e.g. IDENTITY (2435457, 1)
. You might be able to include both the ALTER TABLE...SWITCH
and the DBCC CHECKIDENT
in a transaction (or not-- haven't tested this) but seems like setting the seed value manually will be easier and safer.
Obviously, if no new rows are being added to the table (or they're only added occasionally, like a daily ETL process) then this race condition won't happen so DBCC CHECKIDENT
is fine.
Actually, you will have to use the "?" instead of "&" for your first parameter only. If you use more than one parameter, you will then have to add "&" to the chain.
For instance, if you want to add autoplay and closed captioning, you will have to add this portion to your embedded video URL: ?autoplay=1&cc_load_policy=1.
It would look like this:
<iframe width="420" height="315" src="http://www.youtube.com/embed/
oHg5SJYRHA0?autoplay=1&cc_load_policy=1" frameborder="0"
allowfullscreen></iframe>

I had precisely this problem, but I needed sequential plots to have highly contrasting color. I was also doing plots with a common sub-plot containing reference data, so I wanted the color sequence to be consistently repeatable.
I initially tried simply generating colors randomly, reseeding the RNG before each plot. This worked OK (commented-out in code below), but could generate nearly indistinguishable colors. I wanted highly contrasting colors, ideally sampled from a colormap containing all colors.
I could have as many as 31 data series in a single plot, so I chopped the colormap into that many steps. Then I walked the steps in an order that ensured I wouldn't return to the neighborhood of a given color very soon.
My data is in a highly irregular time series, so I wanted to see the points and the lines, with the point having the 'opposite' color of the line.
Given all the above, it was easiest to generate a dictionary with the relevant parameters for plotting the individual series, then expand it as part of the call.
Here's my code. Perhaps not pretty, but functional.
from matplotlib import cm
cmap = cm.get_cmap('gist_rainbow') #('hsv') #('nipy_spectral')
max_colors = 31 # Constant, max mumber of series in any plot. Ideally prime.
color_number = 0 # Variable, incremented for each series.
def restart_colors():
global color_number
color_number = 0
#np.random.seed(1)
def next_color():
global color_number
color_number += 1
#color = tuple(np.random.uniform(0.0, 0.5, 3))
color = cmap( ((5 * color_number) % max_colors) / max_colors )
return color
def plot_args(): # Invoked for each plot in a series as: '**(plot_args())'
mkr = next_color()
clr = (1 - mkr[0], 1 - mkr[1], 1 - mkr[2], mkr[3]) # Give line inverse of marker color
return {
"marker": "o",
"color": clr,
"mfc": mkr,
"mec": mkr,
"markersize": 0.5,
"linewidth": 1,
}
My context is JupyterLab and Pandas, so here's sample plot code:
restart_colors() # Repeatable color sequence for every plot
fig, axs = plt.subplots(figsize=(15, 8))
plt.title("%s + T-meter"%name)
# Plot reference temperatures:
axs.set_ylabel("°C", rotation=0)
for s in ["T1", "T2", "T3", "T4"]:
df_tmeter.plot(ax=axs, x="Timestamp", y=s, label="T-meter:%s" % s, **(plot_args()))
# Other series gets their own axis labels
ax2 = axs.twinx()
ax2.set_ylabel(units)
for c in df_uptime_sensors:
df_uptime[df_uptime["UUID"] == c].plot(
ax=ax2, x="Timestamp", y=units, label="%s - %s" % (units, c), **(plot_args())
)
fig.tight_layout()
plt.show()
The resulting plot may not be the best example, but it becomes more relevant when interactively zoomed in.

If you always want to just print the iframe from the page, you can have a separate "@media print{}" stylesheet that hides everything besides the iframe. Then you can just print the page normally.
You can just concatenate them.

If you wish to escape HTML in a URL:
This is probably NOT what the OP wanted (the question doesn't clearly indicate in which context the escaping is meant to be used), but Python's native library urllib has a method to escape HTML entities that need to be included in a URL safely.
The following is an example:
#!/usr/bin/python
from urllib import quote
x = '+<>^&'

This problem can be caused by undue manipulation of the enabled cipher suites at the client or the server, but I suspect the most common cause is the server not having a private key and certificate at all.
NB:
ssl.setEnabledCipherSuites(sc.getServerSocketFactory().getSupportedCipherSuites());
Get rid of this line. Your server is insecure enough already with that insecure TrustManager
. Then run your server with -Djavax.net.debug=SSL,handshake,
try one connect, and post the resulting output here.
Use Insert method of List<T>
:
List.Insert Method (Int32, T):
Inserts
an element into the List at thespecified index
.
var names = new List<string> { "John", "Anna", "Monica" };
names.Insert(0, "Micheal"); // Insert to the first element
Strings in c# are immutable. When in your code you do strgroupids.TrimEnd(',');
or strgroupids.TrimEnd(new char[] { ',' });
the strgroupids
string is not modified.
You need to do something like strgroupids = strgroupids.TrimEnd(',');
instead.
To quote from here:
Strings are immutable--the contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this. For example, when you write this code, the compiler actually creates a new string object to hold the new sequence of characters, and that new object is assigned to b. The string "h" is then eligible for garbage collection.
The current recommended best practice from Apple is for IBOutlets to be strong unless weak is specifically needed to avoid a retain cycle. As Johannes mentioned above, this was commented on in the "Implementing UI Designs in Interface Builder" session from WWDC 2015 where an Apple Engineer said:
And the last option I want to point out is the storage type, which can either be strong or weak. In general you should make your outlet strong, especially if you are connecting an outlet to a subview or to a constraint that's not always going to be retained by the view hierarchy. The only time you really need to make an outlet weak is if you have a custom view that references something back up the view hierarchy and in general that's not recommended.
I asked about this on Twitter to an engineer on the IB team and he confirmed that strong should be the default and that the developer docs are being updated.

In Swift, I've created the following helper function:
class func nsobjectToJSON(swiftObject: NSObject) {
var jsonCreationError: NSError?
let jsonData: NSData = NSJSONSerialization.dataWithJSONObject(swiftObject, options: NSJSONWritingOptions.PrettyPrinted, error: &jsonCreationError)!
if jsonCreationError != nil {
println("Errors: \(jsonCreationError)")
}
else {
// everything is fine and we have our json stored as an NSData object. We can convert into NSString
let strJSON : NSString = NSString(data: jsonData, encoding: NSUTF8StringEncoding)!
println("\(strJSON)")
}
}
None of the above answers fixed it for me.
What I had done instead was run pod install
with a pod
command outside of the target
section. So for example:
#WRONG
pod 'SOMEPOD'
target "My Target" do
pod 'OTHERPODS'
end
I quickly fixed it and returned the errant pod back into the target
section where it belonged and ran pod install
again:
# CORRECT
target "My Target" do
pod 'SOMEPOD'
pod 'OTHERPODS'
end
But what happened in the meantime was that the lib -libPods.a
got added to my linked libraries, which doesn't exist anymore and shouldn't since there is already the -libPods-My Target.a
in there.
So the solution was to go into my Target's General settings and go to Linked Frameworks and Libraries and just delete -libPods.a
from the list.
It depends on what you mean:
As mentioned String.hashCode()
gives you a 32 bit hash code.
If you want (say) a 64-bit hashcode you can easily implement it yourself.
If you want a cryptographic hash of a String, the Java crypto libraries include implementations of MD5, SHA-1 and so on. You'll typically need to turn the String into a byte array, and then feed that to the hash generator / digest generator. For example, see @Bryan Kemp's answer.
If you want a guaranteed unique hash code, you are out of luck. Hashes and hash codes are non-unique.
A Java String of length N has 65536 ^ N
possible states, and requires an integer with 16 * N
bits to represent all possible values. If you write a hash function that produces integer with a smaller range (e.g. less than 16 * N
bits), you will eventually find cases where more than one String hashes to the same integer; i.e. the hash codes cannot be unique. This is called the Pigeonhole Principle, and there is a straight forward mathematical proof. (You can't fight math and win!)
But if "probably unique" with a very small chance of non-uniqueness is acceptable, then crypto hashes are a good answer. The math will tell you how big (i.e. how many bits) the hash has to be to achieve a given (low enough) probability of non-uniqueness.
Just adding android:background="?attr/selectableItemBackgroundBorderless"
should work if you don't have background color, but don't forget to use setSelected method. If you have different background color, I just used this (I'm using data-binding);
Set isSelected at onClick function
b.setIsSelected(true);
And add this to xml;
android:background="@{ isSelected ? @color/{color selected} : @color/{color not selected} }"
After 4 hours, of trying everything... Windows 2008 R2 the files were green in Window Explorer. The files were marked for encryption and arching that came from the zip file. unchecking those options in the file property fixed the issue for me.
Swift 4 You cannot compare Any to nil.Because an optional can be nil and hence it always succeeds to true. The only way is to cast it to your desired object and compare it to nil.
if (someone as? String) != nil
{
//your code`enter code here`
}
You can force it to push, but please do this ONLY when you're quite sure what you are doing.
The command is:
git push -f
I'm sorry to disagree, but according to the rules for parsing a legacy color value posted by @Yuhong Bao, chucknorris
DOES NOT equate to #CC0000
, but rather to #C00000
, a very similar but slightly different hue of red. I used the Firefox ColorZilla add-on to verify this.
The rules state:
chucknorris0
chuc knor ris0
ch kn ri
C0 00 00
I was able to use these rules to correctly interpret the following strings:
LuckyCharms
Luck
LuckBeALady
LuckBeALadyTonight
GangnamStyle
UPDATE: The original answerers who said the color was #CC0000
have since edited their answers to include the correction.
As explained above, you can use the Firebase default push id.
If you want something numeric you can do something based on the timestamp to avoid collisions
f.e. something based on date,hour,second,ms, and some random int at the end
01612061353136799031
Which translates to:
016-12-06 13:53:13:679 9031
It all depends on the precision you need (social security numbers do the same with some random characters at the end of the date). Like how many transactions will be expected during the day, hour or second. You may want to lower precision to favor ease of typing.
You can also do a transaction that increments the number id, and on success you will have a unique consecutive number for that user. These can be done on the client or server side.

You'll need to convert any RGB colors into the Lab color space to be able to compare them in the way that humans see them. Otherwise you'll be getting RGB colors that 'match' in some very strange ways.
The wikipedia link on Color Differences gives you an intro into the various Lab color space difference algorithms that have been defined over the years. The simplest that just checks the Euclidian distance of two lab colours, works but has a few flaws.
Conveniently there's a Java implementation of the more sophisticated CIEDE2000 algorithm in the OpenIMAJ project. Provide it your two sets of Lab colours and it'll give you back single distance value.
Answer above is not suitable for complicate Linq expression. All you need is:
// set up the "main query"
var test = from p in _db.test select _db.test;
// if str1 is not null, add a where-condition
if(str1 != null)
{
test = test.Where(p => p.test == str);
}
PriceList[0]
is a float. PriceList[0][1]
is trying to access the first element of a float. Instead, do
PriceList[0] = PriceList[1] = ...code omitted... = PriceList[6] = PizzaChange
or
PriceList[0:7] = [PizzaChange]*7

What happens is, that the JDBC client sends the timezone ID to the Server. The server needs to know that zone. You can check with
SELECT DISTINCT tzname FROM V$TIMEZONE_NAMES where tzname like 'Etc%';
I have some db servers which know about 'Etc/UTC' and 'UTC' (tzfile version 18) but others only know 'UTC' (tz version 11).
SELECT FILENAME,VERSION from V$TIMEZONE_FILE;
There is also different behavior on the JDBC client side. Starting with 11.2 the driver will sent the zone IDs if it is "known" to Oracle, whereas before it sent the time offset. The problem with this "sending of known IDs" is, that the client does not check what timezone version/content is present on the server but has its own list.
This is explained in Oracle Support Article [ID 1068063.1].
It seems it also depends on the Client OS, it was more likely that Etc/UTC fails with Ubuntu than RHEL or Windows. I guess this is due to some normalization but I haven't figured out what exactly.
sometimes you need just to restart Eclipse after the update, it worked for me to fix that error
This will give you the result you're giving as an example:
SELECT DISTINCT a, b
FROM pairs
Ok, solved it myself;
def sout = new StringBuilder(), serr = new StringBuilder()
def proc = 'ls /badDir'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
println "out> $sout\nerr> $serr"
displays:
out> err> ls: cannot access /badDir: No such file or directory

I try to avoid floating elements unless the design really needs it. Because you have floated the <li>
they are out of normal flow.
If you add .navigation { text-align:center; }
and change .navigation li { float: left; }
to .navigation li { display: inline-block; }
then entire navigation will be centred.
One caveat to this approach is that display: inline-block;
is not supported in IE6 and needs a workaround to make it work in IE7.
Some blogs/websites to check out:
Currently, Josh Smith has a "From Russia With Love" article that can be of some use to you.
If you need to be specific on into which folders to copy the file you can combine find with one or more greps. For example to replace any occurences of favicon.ico in any subfolder you can use:
find . | grep favicon\.ico | xargs -n 1 cp -f /root/favicon.ico
Javascript isn't threaded, so a "wait" would freeze the entire page (and probably cause the browser to stop running the script entirely).
To specifically address your problem, you should remove the brackets after donothing
in your setTimeout
call, and make waitsecs
a number not a string:
console.log('before');
setTimeout(donothing,500); // run donothing after 0.5 seconds
console.log('after');
But that won't stop execution; "after" will be logged before your function runs.
To wait properly, you can use anonymous functions:
console.log('before');
setTimeout(function(){
console.log('after');
},500);
All your variables will still be there in the "after" section. You shouldn't chain these - if you find yourself needing to, you need to look at how you're structuring the program. Also you may want to use setInterval
/ clearInterval
if it needs to loop.
A stateful server keeps state between connections. A stateless server does not.
So, when you send a request to a stateful server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between the two requests, that thing is "open" on the server.
When you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.
HTTP and NFS are stateless protocols. Each request stands on its own.
Sometimes cookies are used to add some state to a stateless protocol. In HTTP (web pages), the server sends you a cookie and then the browser holds the state, only to send it back to the server on a subsequent request.
SMB is a stateful protocol. A client can open a file on the server, and the server may deny other clients access to that file until the client closes it.
Just thought I'd chime in with some benchmarks for different scenarios to illustrate the previous answers:
And for each scenario, looking up values which appear:
Before each scenario I generated randomly sized lists of random strings, and then fed each list to a hashset. Each scenario ran 10,000 times, essentially:
(test pseudocode)
stopwatch.start
for X times
exists = list.Contains(lookup);
stopwatch.stop
stopwatch.start
for X times
exists = hashset.Contains(lookup);
stopwatch.stop

Since you are going to work with a DirectoryInfo object anyway, I'd go with an extension
public static bool IsEmpty(this DirectoryInfo directoryInfo)
{
return directoryInfo.GetFileSystemInfos().Count() == 0;
}
You should use raw_input
to take a string input. then use islower
method of str
object.
s = raw_input('Type a word')
l = []
for c in s.strip():
if c.islower():
print c
l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)
Just do -
dir(s)
and you will find islower
and other attributes of str

As a string extension:
public static string RemoveIntegers(this string input)
{
return Regex.Replace(input, @"[\d-]", string.Empty);
}

You can use a regular expression to test for a match and capture the first two digits:
import re
for i in range(1000):
match = re.match(r'(1[56])', str(i))
if match:
print(i, 'begins with', match.group(1))
The regular expression (1[56])
matches a 1 followed by either a 5 or a 6 and stores the result in the first capturing group.
Output:
15 begins with 15
16 begins with 16
150 begins with 15
151 begins with 15

I can offer two options
Based on your description I'm guessing you are doing something like
Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy
ThisWorkbook.Sheets("SomeSheet").Paste
wb2.close
If this is the case, you don't need to copy via the clipboard. This method copies from source to destination directly. No data in clipboard = no prompt
Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy ThisWorkbook.Sheets("SomeSheet").Cells(<YourCell")
wb2.close
You can prevent all alert pop-ups by setting
Application.DisplayAlerts = False
[Edit]
Dim rSrc As Range
Dim rDst As Range
Set rSrc = wb2.Sheets("YourSheet").Range("YourRange")
Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)
rDst = rSrc.Value
Dim fileEntries As String() = Directory.GetFiles("YourPath", "*.txt")
' Process the list of .txt files found in the directory. '
Dim fileName As String
For Each fileName In fileEntries
If (System.IO.File.Exists(fileName)) Then
'Read File and Print Result if its true
ReadFile(fileName)
End If
TransfereFile(fileName, 1)
Next
The above options works for Google big query file also. I exported a table data to goodle cloud storage and downloaded from there. While loading the same to sql server was facing this issue and could successfully load the file after specifying the row delimiter as
ROWTERMINATOR = '0x0a'
Pay attention to header record as well and specify
FIRSTROW = 2
My final block for data file export from google bigquery looks like this.
BULK INSERT TABLENAME
FROM 'C:\ETL\Data\BigQuery\In\FILENAME.csv'
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = ',', --CSV field delimiter
ROWTERMINATOR = '0x0a',--Files are generated with this row terminator in Google Bigquery
TABLOCK
)
A silly hack I did was to set the height of the element to zero but overflow:visible; combining this with pointer-events:none; seems to cover all the bases.
.overlay {
height:0px;
overflow:visible;
pointer-events:none;
background:none !important;
}
Try this instead in the end:
exec (@query)
If you do not have the brackets, SQL Server assumes the value of the variable to be a stored procedure name.
OR
EXECUTE sp_executesql @query
And it should not be because of FULL JOIN.
But I hope you have already created the temp tables: #TrafficFinal, #TrafficFinal2, #TrafficFinal3 before this.
Please note that there are performance considerations between using EXEC and sp_executesql. Because sp_executesql uses forced statement caching like an sp.
More details here.
On another note, is there a reason why you are using dynamic sql for this case, when you can use the query as is, considering you are not doing any query manipulations and executing it the way it is?
Try Winhttrack
...offline browser utility.
It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads. HTTrack is fully configurable, and has an integrated help system.
WinHTTrack is the Windows 2000/XP/Vista/Seven release of HTTrack, and WebHTTrack the Linux/Unix/BSD release...
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
The /me/friendlists
endpoint and user_friendlists
permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission).
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
Try with enabling the sub-thread as daemon-thread.
Recommended:
from threading import Thread
t = Thread(target=<your-method>)
t.daemon = True # This thread dies when main thread (only non-daemon thread) exits.
t.start()
Inline:
t = Thread(target=<your-method>, daemon=True).start()
Old API:
t.setDaemon(True)
t.start()
When your main thread terminates ("i.e. when I press Ctrl+C"), other threads will also be killed by the instructions above.
If you want your application to open the link in a web browser you need to add a HyperLink with the RequestNavigate event set to a function that programmatically opens a web-browser with the address as a parameter.
<TextBlock>
<Hyperlink NavigateUri="http://www.google.com" RequestNavigate="Hyperlink_RequestNavigate">
Click here
</Hyperlink>
</TextBlock>
In the code-behind you would need to add something similar to this to handle the RequestNavigate event:
private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
// for .NET Core you need to add UseShellExecute = true
// see https://docs.microsoft.com/dotnet/api/system.diagnostics.processstartinfo.useshellexecute#property-value
Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
e.Handled = true;
}
In addition you will also need the following imports:
using System.Diagnostics;
using System.Windows.Navigation;
It will look like this in your application:
long n = long.Parse(date.ToString("yyyyMMddHHmmss"));
A simple and basic OS development tutorial designed to be a semester's project. It guides you through to build an OS with basic components. Very good start for beginners. Related paper is here.
As Matt has said, use Console.Write
. I would also recommend explicitly flushing the output, however - I believe WriteLine
does this automatically, but I'd seen oddities when just using Console.Write
and then waiting. So Matt's code becomes:
Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();
Try this:
$(":focus").each(function() {
alert("Focused Elem_id = "+ this.id );
});
atan(x) Returns the principal value of the arc tangent of x, expressed in radians.
atan2(y,x) Returns the principal value of the arc tangent of y/x, expressed in radians.
Notice that because of the sign ambiguity, a function cannot determine with certainty in which quadrant the angle falls only by its tangent value (atan alone). You can use atan2 if you need to determine the quadrant.
Ok, something odd is happening here. To make this work, do NOT need to make any configuration changes in /etc/mysql/my.cnf . All you need to do is to restart the current mysql service in terminal:
sudo service mysql restart
Then if I want to "recreate" the bug, I simply restart the apache service:
sudo service apache2 restart
Which can then be fixed again by entering the following command:
sudo service mysql restart
So, it appears that the apache2 is doing something to not allow this feature when it starts up (which is then reversed/corrected if restart the mysql service).
Valid in Debian based distributions.
service mysqld restart
service httpd restart
Valid in RedHat based distributions
MooTools (My Object Oriented Tools) is centered on the idea of classes. You can even extend and implement with inheritance.
When mastered, it makes for ridiculously reusable, powerful javascript.
You can use this delegate method from UITextFieldDelegate. It fires with every character change.
(Objective C) textField:shouldChangeCharactersInRange:replacementString:
(Swift) textField(_:shouldChangeCharactersInRange:replacementString:)
However THIS ONLY FIRES BEFORE a change is made (indeed, a change is only made if you do return true from here).
you need to stop that service running on this port .check service running on specific port by "netstat -ano".then in window search type services.exe and search that process and stop that process .to change port of that process check this http://seankilleen.com/2012/11/how-to-stop-sql-server-reporting-services-from-using-port-80-on-your-server-field-notes/
Once I used double slash while calling the API then I got the same error.
I had to call http://localhost:8080/getSomething but I did Like http://localhost:8080//getSomething. I resolved it by removing extra slash.
Use Scanner.hasNextInt()
:
Returns
true
if the next token in this scanner's input can be interpreted as anint
value in the default radix using thenextInt()
method. The scanner does not advance past any input.
Here's a snippet to illustrate:
Scanner sc = new Scanner(System.in);
System.out.print("Enter number 1: ");
while (!sc.hasNextInt()) sc.next();
int num1 = sc.nextInt();
int num2;
System.out.print("Enter number 2: ");
do {
while (!sc.hasNextInt()) sc.next();
num2 = sc.nextInt();
} while (num2 < num1);
System.out.println(num1 + " " + num2);
You don't have to parseInt
or worry about NumberFormatException
. Note that since the hasNextXXX
methods don't advance past any input, you may have to call next()
if you want to skip past the "garbage", as shown above.
In your comparator factory class, do something like this:
private static final Comparator<String> MYSTRING_COMPARATOR = new Comparator<String>() {
@Override
public int compare(String s1, String s2) {
return s1.compareToIgnoreCase(s2);
}
};
public static Comparator<String> getMyStringComparator() {
return MYSTRING_COMPARATOR;
This uses the compare to method which is case insensitive (why write your own). This way you can use Collections sort like this:
List<String> myArray = new ArrayList<String>();
//fill your array here
Collections.sort(MyArray, MyComparators. getMyStringComparator());
Go to xampp-control in the Taskbar
xampp-control -> Apache --> Config --> httpd.conf
Notepad will open with the config file
Search for
Listen 80
One line above it, there will be something like this: 12.34.56:80
Change it
12.34.56:80 --> <your_ip_address eg:192.168.1.5>:80
Restart the apache service and check it, Hopefully it should work...

In addition to what others have said, note that a single character in unicode can consist of multiple bytes.
The way unicode works is that it took the old ASCII format (7-bit code that looks like 0xxx xxxx) and added multi-bytes sequences where all bytes start with 1 (1xxx xxxx) to represent characters beyond ASCII so that Unicode would be backwards-compatible with ASCII.
>>> len('Öl') # German word for 'oil' with 2 characters
2
>>> 'Öl'.encode('UTF-8') # convert str to bytes
b'\xc3\x96l'
>>> len('Öl'.encode('UTF-8')) # 3 bytes encode 2 characters !

I would suggest you read the appropriate sections in The Java Tutorial from Sun:
http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html
To remove the default text, on clicking the element:
$('input:text').click(
function(){
$(this).val('');
});
I would, though, suggest using focus()
instead:
$('input:text').focus(
function(){
$(this).val('');
});
Which responds to keyboard events too (the tab key, for example). Also, you could use the placeholder
attribute in the element:
<input type="text" placeholder="default text" />
Which will clear on focus of the element, and reappear if the element remains empty/user doesn't input anything.
A simple solution using streams:
int n = 321;
int sum = String.valueOf(n)
.chars()
.map(Character::getNumericValue)
.sum();
If every input asks the same question, you should use a for
loop and an array of inputs:
Scanner dd = new Scanner(System.in);
int[] vars = new int[3];
for(int i = 0; i < vars.length; i++) {
System.out.println("Enter next var: ");
vars[i] = dd.nextInt();
}
Or as Chip suggested, you can parse the input from one line:
Scanner in = new Scanner(System.in);
int[] vars = new int[3];
System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
vars[i] = in.nextInt();
You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.
I have a workaround using jquery... although we cannot style a particular option, we can style the select itself - and use javascript to change the class of the select based on what is selected. It works sufficiently for simple cases.
$('select.potentially_red').on('change', function() {_x000D_
if ($(this).val()=='red') {_x000D_
$(this).addClass('option_red');_x000D_
} else {_x000D_
$(this).removeClass('option_red');_x000D_
}_x000D_
});_x000D_
$('select.potentially_red').each( function() {_x000D_
if ($(this).val()=='red') {_x000D_
$(this).addClass('option_red');_x000D_
} else {_x000D_
$(this).removeClass('option_red');_x000D_
}_x000D_
});
_x000D_
.option_red {_x000D_
background-color: #cc0000; _x000D_
font-weight: bold; _x000D_
font-size: 12px; _x000D_
color: white;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
<!-- The js will affect all selects which have the class 'potentially_red' -->_x000D_
<select name="color" class="potentially_red">_x000D_
<option value="red">Red</option>_x000D_
<option value="white">White</option>_x000D_
<option value="blue">Blue</option>_x000D_
<option value="green">Green</option>_x000D_
</select>
_x000D_
Note that the js is in two parts, the each
part for initializing everything on the page correctly, the .on('change', ...
part for responding to change. I was unable to mangle the js into a function to DRY it up, it breaks it for some reason

You can do the following:
df =DataFrame({'a':[1,2,3,4],'b':[2,4,6,8]})
df['x']=df.a + df.b
df['y']=df.a - df.b
create column title whatever order you want in this way:
column_titles = ['x','y','a','b']
df.reindex(columns=column_titles)
This will give you desired output
Notifications may not be shown if you show the notifications rapidly one after the other or cancel an existing one, then right away show it again (e.g. to trigger a heads-up-notification to notify the user about a change in an ongoing notification). In these cases the system may decide to just block the notification when it feels they might become too overwhelming/spammy for the user.
Please note, that at least on stock Android (tested with 10) from the outside this behavior looks a bit random: it just sometimes happens and sometimes it doesn't. My guess is, there is a very short time threshold during which you are not allowed to send too many notifications. Calling NotificationManager.cancel()
and then NotificationManager.notify()
might then sometimes cause this behavior.
If you have the option, when updating a notification don't cancel it before, but just call NotificationManager.notify()
with the updated notification. This doesn't seem to trigger the aforementioned blocking by the system.
A parameterized constructor is generated with the selected members.
Did you try adding the self prefix to the fileName and replacing the method above the Button ? With the self, it becomes visible between methods.
...
def load_file(self):
self.fileName = filedialog.askopenfilename(filetypes = (("Template files", "*.tplate")
,("HTML files", "*.html;*.htm")
,("All files", "*.*") ))

This will also work:
import java.io.*;
public class IOUtil {
public static byte[] readFile(String file) throws IOException {
return readFile(new File(file));
}
public static byte[] readFile(File file) throws IOException {
// Open file
RandomAccessFile f = new RandomAccessFile(file, "r");
try {
// Get and check length
long longlength = f.length();
int length = (int) longlength;
if (length != longlength)
throw new IOException("File size >= 2 GB");
// Read file and return data
byte[] data = new byte[length];
f.readFully(data);
return data;
} finally {
f.close();
}
}
}
If you removed the make all
line from your "fresh" target:
fresh :
rm -f *.o $(EXEC)
clear
You could simply run the command make fresh all
, which will execute as make fresh; make all
.
Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.
%0|%0
is a fork bomb. It will spawn another process using a pipe |
which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).
%0
refers to the command used to run the current program. For example, script.bat
A pipe |
symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.
Expanding the example, %0|%0
could mean script.bat|script.bat
. This runs itself again, but also creating another process to run the same program again (with no input).
You should also consider using libraries to do that: they allow limiting and much more:
FineUploader. Demo using validation.itemLimit
as of 5.16.2:
var restrictedUploader = new qq.FineUploader({
validation: {
itemLimit: 3,
}
});
bluimp's jQuery File Upload Plugin. Usage: jquery file upload restricting number of files using maxNumberOfFiles
as of v9.22.0:
$('#fileuploadbasic').fileupload({
maxNumberOfFiles: 6
});
They are also available at https://cdnjs.com/
Silly workaround that always works.
$state.go("otherState").then(function(){

Just Do like this
view.animate()
.translationY(-((root.height - (view.height)) / 2).toFloat())
.setInterpolator(AccelerateInterpolator()).duration = 1500
Here, view
is your View which is animating from its origin position. root
is root View of your XML file.
Calculation inside translationY
is made for moving your view to the top but keeping it inside the screen, otherwise, it will go partially outside of the screen if you keep its value 0.
i didn't know that the ".stop()" is necessary.
$(window).scroll(function () {
var scroll = $(window).scrollTop();
console.log(scroll);
if (scroll >= 50){
$('.sidebar-padder').stop().animate({ 'height': '380px'}, 1000);
}else{
$('.sidebar-padder').stop().animate({ 'height': '600px'}, 1000);
};
In Net Core 3.0:
I was not able to find a way to Reset Migrations.
I also ran into problems with broken migrations, and the answers provided here didn't work for me. I have a .Net Core 3.0 web API, and somewhere in the last month I edited the database directly. Yes, I did a bad, bad thing.
Strategies suggested here resulted in a number of errors in Package Manager Console:
Granted, I may have missed a step or missed clearing out the correct files, but I found that there are ways to clean this up without as much brute force:
Now when the web API is started with an empty database, it correctly creates all the tables and properties to match the entity models.
HTH!
You can set the default search_path
at the database level:
ALTER DATABASE <database_name> SET search_path TO schema1,schema2;
Or at the user or role level:
ALTER ROLE <role_name> SET search_path TO schema1,schema2;
Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.
When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name>
to create your databases.
I guess your problem is that jQuery is not loaded in your iframes.
The safest approach is to rely on pure DOM-based methods to parse your content.
Or else, start with jQuery, and then once inside your iframes, test once if typeof window.jQuery == 'undefined'
, if it's true, jQuery is not enabled inside it and fallback on DOM-based method.
"final" also allows a compiler optimization to bypass the indirect call:
class IAbstract
{
public:
virtual void DoSomething() = 0;
};
class CDerived : public IAbstract
{
void DoSomething() final { m_x = 1 ; }
void Blah( void ) { DoSomething(); }
};
with "final", the compiler can call CDerived::DoSomething()
directly from within Blah()
, or even inline. Without it, it has to generate an indirect call inside of Blah()
because Blah()
could be called inside a derived class which has overridden DoSomething()
.
There are cross browser issues here.
A typical non-jQuery event handler would be something like this :
function doSomething(evt) {
evt = evt || window.event;
var target = evt.target || evt.srcElement;
if (target.nodeType == 3) // defeat Safari bug
target = target.parentNode;
//do stuff here
}
jQuery normalises evt
and makes the target available as this
in event handlers, so a typical jQuery event handler would be something like this :
function doSomething(evt) {
var $target = $(this);
//do stuff here
}
A hybrid event handler which uses jQuery's normalised evt
and a POJS target would be something like this :
function doSomething(evt) {
var target = evt.target || evt.srcElement;
if (target.nodeType == 3) // defeat Safari bug
target = target.parentNode;
//do stuff here
}

You can access the current url quite easily in JavaScript with window.location
You have access to the segments of that URL via this locations
object. For example:
// This article:
// https://stackoverflow.com/questions/21246818/how-to-get-the-base-url-in-javascript
var base_url = window.location.origin;
// "http://stackoverflow.com"
var host = window.location.host;
// stackoverflow.com
var pathArray = window.location.pathname.split( '/' );
// ["", "questions", "21246818", "how-to-get-the-base-url-in-javascript"]
In Chrome Dev Tools, you can simply enter window.location
in your console and it will return all of the available properties.

Use the splice method.
(At least I assume that is the answer, you say you have an object, but the code you give just creates two variables, and there is no sign of how the Array is created)
Use include("class.classname.php");
And class should use <?php //code ?> not <? //code ?>
