Yes:
const encstr = (`TextEncoder` in window) ? new TextEncoder().encode(str) : Uint8Array.from(str, c => c.codePointAt(0));
This is an async method which first checks for the availability of arrayBuffer
method. This function is backward compatible and future proof.
async function blobToArrayBuffer(blob) {
if ('arrayBuffer' in blob) return await blob.arrayBuffer();
return new Promise((resolve, reject) => {
const reader = new FileReader();
reader.onload = () => resolve(reader.result);
reader.onerror = () => reject;
reader.readAsArrayBuffer(blob);
});
}
The methods readAsArrayBuffer and readAsText from a FileReader object converts a Blob object to an ArrayBuffer or to a DOMString asynchronous.
A Blob object type can be created from a raw text or byte array, for example.
let blob = new Blob([text], { type: "text/plain" });
let reader = new FileReader();
reader.onload = event =>
{
let buffer = event.target.result;
};
reader.readAsArrayBuffer(blob);
I think it's better to pack up this in a promise:
function textToByteArray(text)
{
let blob = new Blob([text], { type: "text/plain" });
let reader = new FileReader();
let done = function() { };
reader.onload = event =>
{
done(new Uint8Array(event.target.result));
};
reader.readAsArrayBuffer(blob);
return { done: function(callback) { done = callback; } }
}
function byteArrayToText(bytes, encoding)
{
let blob = new Blob([bytes], { type: "application/octet-stream" });
let reader = new FileReader();
let done = function() { };
reader.onload = event =>
{
done(event.target.result);
};
if(encoding) { reader.readAsText(blob, encoding); } else { reader.readAsText(blob); }
return { done: function(callback) { done = callback; } }
}
let text = "\uD83D\uDCA9 = \u2661";
textToByteArray(text).done(bytes =>
{
console.log(bytes);
byteArrayToText(bytes, 'UTF-8').done(text =>
{
console.log(text); // = ?
});
});
Use the following excellent npm package: to-arraybuffer
.
Or, you can implement it yourself. If your buffer is called buf
, do this:
buf.buffer.slice(buf.byteOffset, buf.byteOffset + buf.byteLength)
The OP did not specify the Running Enviroment but if you are using Node.JS there is a very simple way to do such thing.
Accordig with the official Node.JS docs https://nodejs.org/api/buffer.html#buffer_buffers_and_character_encodings
// This step is only necessary if you don't already have a Buffer Object
const buffer = Buffer.from(yourArrayBuffer);
const base64String = buffer.toString('base64');
Also, If you are running under Angular for example, the Buffer Class will also be made available in a Browser Environment.
I would strongly suggest using an npm package implementing correctly the base64 specification.
The best one I know is rfc4648
The problem is that btoa and atob use binary strings instead of Uint8Array and trying to convert to and from it is cumbersome. Also there is a lot of bad packages in npm for that. I lose a lot of time before finding that one.
The creators of that specific package did a simple thing: they took the specification of Base64 (which is here by the way) and implemented it correctly from the beginning to the end. (Including other formats in the specification that are also useful like Base64-url, Base32, etc ...) That doesn't seem a lot but apparently that was too much to ask to the bunch of other libraries.
So yeah, I know I'm doing a bit of proselytism but if you want to avoid losing your time too just use rfc4648.
Use
position:absolute;
right: 0;
No need for float:right
with absolute positioning
Also, make sure the parent element is set to position:relative;
You can add join type as well:
Criteria c2 = c.createCriteria("mother", "mother", CriteriaSpecification.LEFT_JOIN);
Criteria c3 = c2.createCriteria("kind", "kind", CriteriaSpecification.LEFT_JOIN);
With ES6 arrow functions it will be like this:
//Let's say we have these cars
let cars = [ { brand: 'Porsche', top_speed: 260 },
{ brand: 'Benz', top_speed: 110 },
{ brand: 'Fiat', top_speed: 90 },
{ brand: 'Aston Martin', top_speed: 70 } ]
Array.prototype.sort()
can accept a comparator function (here I used arrow notation, but ordinary functions work the same):
let sortedByBrand = [...cars].sort((first, second) => first.brand > second.brand)
// [ { brand: 'Aston Martin', top_speed: 70 },
// { brand: 'Benz', top_speed: 110 },
// { brand: 'Fiat', top_speed: 90 },
// { brand: 'Porsche', top_speed: 260 } ]
The above approach copies the contents of cars array into a new one and sorts it alphabetically based on brand names. Similarly, you can pass a different function:
let sortedBySpeed =[...cars].sort((first, second) => first.top_speed > second.top_speed)
//[ { brand: 'Aston Martin', top_speed: 70 },
// { brand: 'Fiat', top_speed: 90 },
// { brand: 'Benz', top_speed: 110 },
// { brand: 'Porsche', top_speed: 260 } ]
If you don't mind mutating the orginal array cars.sort(comparatorFunction)
will do the trick.
It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==
, the following should work:
byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);
This will output: YWJjZGVmPT0=
which is abcdef==
encoded in Base64.
Edit:
To decode a Base64 string, simply use Convert.FromBase64String()
. E.g.
string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);
At this point, bytes
will be a byte[]
(not a string
). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:
string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);
This will output the original input string, abcdef==
in this case.
You can get the above output using following code in c
#include<stdio.h>
#include<conio.h>
#include<string.h>
int main()
{
char *str;
clrscr();
printf("\n Enter the string");
gets(str);
for(int i=0;i<strlen(str)-1;i++)
{
for(int j=i;j<=i+1;j++)
printf("%c",str[j]);
printf("\t");
}
getch();
return 0;
}
A complementary note about CREATE TABLE .. TYPE=""
syntax in SQL dump files
TLDR: If you still get CREATE TABLE ... TYPE="..."
statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode
of MYSQL40
or MYSQL323
.
Long story
As it was said by others, the TYPE
argument to CREATE TABLE
has been deprecated for a long time in MySQL. mysqldump
correctly uses the ENGINE
argument, unless you specifically ask it to generate a backward compatible dump (for example using --compatible=mysql40
in versions of mysqldump
up to 5.7).
However, many external SQL dump tools (for example, those integrated in MySQL clients such as phpmyadmin, Navicat and DBVisualizer, as well as those used by external automated backup services such as iControlWP) are not specifically aware of this change, and instead rely on the SHOW CREATE TABLE ...
command to provide table creation statements for each tables (and just to it make it clear: this is actually a good thing). However, the SHOW CREATE TABLE
will actually produce outdated syntax, including the TYPE
argument, if the sqlmode
variable is set to MYSQL40
or MYSQL323
.
Therefore, if you still get CREATE TABLE ... TYPE="..."
statements in SQL dump files generated by third party tools, it most certainly indicates that your server is configured to use a default sqlmode
of MYSQL40
or MYSQL323
.
These sqlmode
s basically configure MySQL to retain some backward compatible behaviours, and using them by default was largely recommended a few years ago. It is however highly improbable that you still have any code that wouldn't work correctly without these modes. Anyway, MYSQL40
, MYSQL323
and several other similar sqlmode
s have themselves been deprecated and are not supported in MySQL 8.0 and higher.
If your server is still configured with these sqlmode
s and you are worried that some legacy program might fail if you change these, then one possibility is to set the sqlmode
locally for that program, by executing SET SESSION sql_mode = 'MYSQL40';
immediately after connection. Note that this should only be considered as a temporary patch, and will not work in MySQL 8.0 and higher.
A more future-proof solution that do not involve rewriting your SQL queries would be to determine exactly which compatibility features need to be enable, and to enable only those, on a per-program basis (as described previously). The default sqlmode
(that is, in server's configuration) should ideally be left unset (which will use official MySQL defaults for your current version). The full list of sqlmode
(as of MySQL 5.7) is described here: https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html.
This does what you want, I think:
git log --all --pretty=format: --name-only --diff-filter=D | sort -u
... which I've just taken more-or-less directly from this other answer.
#father {
position: relative;
}
#son1 {
position: absolute;
top: 0;
}
#son2 {
position: absolute;
bottom: 0;
}
This works because position: absolute
means something like "use top
, right
, bottom
, left
to position yourself in relation to the nearest ancestor who has position: absolute
or position: relative
."
So we make #father
have position: relative
, and the children have position: absolute
, then use top
and bottom
to position the children.
I use Postman.
Execute whatever call you want to do. Then, postman provides a handy tool to show the curl code .
As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with
<html>
<head>
<title>runthis</title>
<script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(document).ready( function() {
var x = $("#foo").html();
alert( typeof(x) );
});
</script>
</head>
<body>
<div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
</body>
</html>
The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.
edit: Don't pass a string as the parameter data to .post() but an object, like
var data = {
id: currid,
html: div_html
};
$.post("http://...", data, ...);
jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().
var data = 'id='+ escape(currid) +'&html='+ escape(div_html);
Goto Advanced tab----> data type of column---> Here change data type from DT_STR to DT_TEXT and column width 255. Now you can check it will work perfectly.
Simple short answer is this:
xcopy /Y /I "$(SolutionDir)<my-src-path>" "$(SolutionDir)<my-dst-path>\"
Demo link: https://github.com/RazvanSebastian/spring_multiple_log_files_demo.git
My solution is based on XML configuration using spring-boot-starter-log4j
. The example is a basic example using spring-boot-starter
and the two Loggers writes into different log files.
Here goes my humble attempt to explain the concept to newbies around the world: (a color coded version on my blog too)
A lot of people run to a lone phone booth (they don't have mobile phones) to talk to their loved ones. The first person to catch the door-handle of the booth, is the one who is allowed to use the phone. He has to keep holding on to the handle of the door as long as he uses the phone, otherwise someone else will catch hold of the handle, throw him out and talk to his wife :) There's no queue system as such. When the person finishes his call, comes out of the booth and leaves the door handle, the next person to get hold of the door handle will be allowed to use the phone.
A thread is : Each person
The mutex is : The door handle
The lock is : The person's hand
The resource is : The phone
Any thread which has to execute some lines of code which should not be modified by other threads at the same time (using the phone to talk to his wife), has to first acquire a lock on a mutex (clutching the door handle of the booth). Only then will a thread be able to run those lines of code (making the phone call).
Once the thread has executed that code, it should release the lock on the mutex so that another thread can acquire a lock on the mutex (other people being able to access the phone booth).
[The concept of having a mutex is a bit absurd when considering real-world exclusive access, but in the programming world I guess there was no other way to let the other threads 'see' that a thread was already executing some lines of code. There are concepts of recursive mutexes etc, but this example was only meant to show you the basic concept. Hope the example gives you a clear picture of the concept.]
With C++11 threading:
#include <iostream>
#include <thread>
#include <mutex>
std::mutex m;//you can use std::lock_guard if you want to be exception safe
int i = 0;
void makeACallFromPhoneBooth()
{
m.lock();//man gets a hold of the phone booth door and locks it. The other men wait outside
//man happily talks to his wife from now....
std::cout << i << " Hello Wife" << std::endl;
i++;//no other thread can access variable i until m.unlock() is called
//...until now, with no interruption from other men
m.unlock();//man lets go of the door handle and unlocks the door
}
int main()
{
//This is the main crowd of people uninterested in making a phone call
//man1 leaves the crowd to go to the phone booth
std::thread man1(makeACallFromPhoneBooth);
//Although man2 appears to start second, there's a good chance he might
//reach the phone booth before man1
std::thread man2(makeACallFromPhoneBooth);
//And hey, man3 also joined the race to the booth
std::thread man3(makeACallFromPhoneBooth);
man1.join();//man1 finished his phone call and joins the crowd
man2.join();//man2 finished his phone call and joins the crowd
man3.join();//man3 finished his phone call and joins the crowd
return 0;
}
Compile and run using g++ -std=c++0x -pthread -o thread thread.cpp;./thread
Instead of explicitly using lock
and unlock
, you can use brackets as shown here, if you are using a scoped lock for the advantage it provides. Scoped locks have a slight performance overhead though.
You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.
There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).
*args
just means that the function takes a number of arguments, generally of the same type.
Check out this section in the Python tutorial for more info.
BEGIN
FOR r IN (select sid,serial# from v$session where username='user')
LOOP
EXECUTE IMMEDIATE 'alter system kill session ''' || r.sid || ',' || r.serial# || '''';

If it gets into the selinux arena you've got a much more complicated issue. It's not a good idea to remove the selinux protection but to embrace it and use the tools that were designed to manage it.
If you are serving content out of /var/www/abc
, you can verify the selinux permissions with a Z
appended to the normal ls -l
command. i.e. ls -laZ
will give the selinux context.
To add a directory to be served by selinux you can use the semanage
command like this. This will change the label on /var/www/abc
to httpd_sys_content_t
semanage fcontext -a -t httpd_sys_content_t /var/www/abc
this will update the label for /var/www/abc
restorecon /var/www/abc
This answer was taken from unixmen and modified to fit this question. I had been searching for this answer for a while and finally found it so felt like I needed to share somewhere. Hope it helps someone.
Actually, in VS Code 1.48.1, there is a toggleTerminal
command; I don't know if it was available in previous versions ;) You can utilize it in the keybindings.json
file.
This worked for me on Windows, and should also works on Linux.

"key": "ctrl+alt+right",
"command": "workbench.action.terminal.toggleTerminal",
"when": "editorTextFocus || terminalFocus"
}
If you want to use default value for a DateTime parameter in a method, you can only use default(DateTime).
The following line will not compile:
private void MyMethod(DateTime syncedTime = DateTime.MinValue)
This line will compile:
private void MyMethod(DateTime syncedTime = default(DateTime))
A simple function to get UNIX Epoch time.
NOTE: This function assumes the input date time is in UTC format (Refer to comments here).
def utctimestamp(ts: str, DATETIME_FORMAT: str = "%d/%m/%Y"):
import datetime, calendar
ts = datetime.datetime.utcnow() if ts is None else datetime.datetime.strptime(ts, DATETIME_FORMAT)
return calendar.timegm(ts.utctimetuple())
Usage:
>>> utctimestamp("01/12/2011")
1322697600
>>> utctimestamp("2011-12-01", "%Y-%m-%d")
1322697600
try:
public ActionResult MyNextAction()
{
return Redirect(Request.UrlReferrer.ToString());
}
alternatively, touching on what darin said, try this:
public ActionResult MyFirstAction()
{
return RedirectToAction("MyNextAction",
new { r = Request.Url.ToString() });
}
then:
public ActionResult MyNextAction()
{
return Redirect(Request.QueryString["r"]);
}
Actually, on 32-bit computers a word is 32-bit, but the DWORD type is a leftover from the good old days of 16-bit.
In order to make it easier to port programs to the newer system, Microsoft has decided all the old types will not change size.
You can find the official list here: http://msdn.microsoft.com/en-us/library/aa383751(VS.85).aspx
All the platform-dependent types that changed with the transition from 32-bit to 64-bit end with _PTR (DWORD_PTR will be 32-bit on 32-bit Windows and 64-bit on 64-bit Windows).
I solved the same issue 10 minutes ago, so I will give you a short effective fix: Place this inside the application tag or your manifest:
android:theme="@android:style/Theme.Holo"
Also set the Theme of your XML layout to Holo, in the layout's graphical view.
Libraries will be useful if you need to change more complicated theme stuff, but this little fix will work, so you can move on with your app.

send_emai()
didn't work for me so I used EmailMessage
here in django docs.
I have included two versions of the anser:
from django.template.loader import render_to_string
from django.core.mail import EmailMessage
# import file with html content
html_version = 'path/to/html_version.html'
html_message = render_to_string(html_version, { 'context': context, })
message = EmailMessage(subject, html_message, from_email, [to_email])
message.content_subtype = 'html' # this is required because there is no plain text email version
message.send()
If you want to include a plain text version of your email, modify the above like this:
from django.template.loader import render_to_string
from django.core.mail import EmailMultiAlternatives # <= EmailMultiAlternatives instead of EmailMessage
plain_version = 'path/to/plain_version.html' # import plain version. No html content
html_version = 'path/to/html_version.html' # import html version. Has html content
plain_message = render_to_string(plain_version, { 'context': context, })
html_message = render_to_string(html_version, { 'context': context, })
message = EmailMultiAlternatives(subject, plain_message, from_email, [to_email])
message.attach_alternative(html_message, "text/html") # attach html version
message.send()
My plain and html versions look like this: plain_version.html:
Plain text {{ context }}
html_version.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Curious about the exact sequence of events, I instrumented an app as follows: (@Zohaib, you can use the NSNotificationCenter code below to answer your question).
// AppDelegate.m
- (void)applicationWillEnterForeground:(UIApplication *)application
{
NSLog(@"app will enter foreground");
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
NSLog(@"app did become active");
}
// ViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"view did load");
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillEnterForeground:) name:UIApplicationWillEnterForegroundNotification object:nil];
}
- (void)appDidBecomeActive:(NSNotification *)notification {
NSLog(@"did become active notification");
}
- (void)appWillEnterForeground:(NSNotification *)notification {
NSLog(@"will enter foreground notification");
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSLog(@"view will appear");
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSLog(@"view did appear");
}
At launch, the output looks like this:
2013-04-07 09:31:06.505 myapp[15459:11303] view did load
2013-04-07 09:31:06.507 myapp[15459:11303] view will appear
2013-04-07 09:31:06.511 myapp[15459:11303] app did become active
2013-04-07 09:31:06.512 myapp[15459:11303] did become active notification
2013-04-07 09:31:06.517 myapp[15459:11303] view did appear
Enter the background then reenter the foreground:
2013-04-07 09:32:05.923 myapp[15459:11303] app will enter foreground
2013-04-07 09:32:05.924 myapp[15459:11303] will enter foreground notification
2013-04-07 09:32:05.925 myapp[15459:11303] app did become active
2013-04-07 09:32:05.926 myapp[15459:11303] did become active notification
You need remove path.moveTo after first initial.
Path path = new Path();
path.moveTo(point1_returned.x, point1_returned.y);
path.lineTo(point2_returned.x, point2_returned.y);
path.lineTo(point3_returned.x, point3_returned.y);
path.lineTo(point1_returned.x, point1_returned.y);
path.close();
If you override the equality of People then you can also use:
peopleList2.Except(peopleList1)
Except
should be significantly faster than the Where(...Any)
variant since it can put the second list into a hashtable. Where(...Any)
has a runtime of O(peopleList1.Count * peopleList2.Count)
whereas variants based on HashSet<T>
(almost) have a runtime of O(peopleList1.Count + peopleList2.Count)
.
Except
implicitly removes duplicates. That shouldn't affect your case, but might be an issue for similar cases.
Or if you want fast code but don't want to override the equality:
var excludedIDs = new HashSet<int>(peopleList1.Select(p => p.ID));
var result = peopleList2.Where(p => !excludedIDs.Contains(p.ID));
This variant does not remove duplicates.
A temp table can be created in the caller and then populated from the called SP.
create table #GetValuesOutputTable(
...
);
exec GetValues; -- populates #GetValuesOutputTable
select * from #GetValuesOutputTable;
Some advantages of this approach over the "insert exec" is that it can be nested and that it can be used as input or output.
Some disadvantages are that the "argument" is not public, the table creation exists within each caller, and that the name of the table could collide with other temp objects. It helps when the temp table name closely matches the SP name and follows some convention.
Taking it a bit farther, for output only temp tables, the insert-exec approach and the temp table approach can be supported simultaneously by the called SP. This doesn't help too much for chaining SP's because the table still need to be defined in the caller but can help to simplify testing from the cmd line or when calling externally.
-- The "called" SP
declare
@returnAsSelect bit = 0;
if object_id('tempdb..#GetValuesOutputTable') is null
begin
set @returnAsSelect = 1;
create table #GetValuesOutputTable(
...
);
end
-- populate the table
if @returnAsSelect = 1
select * from #GetValuesOutputTable;
An example.
$query_new = "INSERT INTO students(courseid, coursename) VALUES ('', ?)";
$query_new = $databaseConnection->prepare($query_new);
$query_new->bind_param('s', $_POST['coursename']);
$query_new->execute();
$course_id = $query_new->insert_id;
$query_new->close();
The code line $course_id = $query_new->insert_id;
will display the ID of the last inserted row.
Hope this helps.
float
stores floating-point values, that is, values that have potential decimal placesint
only stores integral values, that is, whole numbersSo while both are 32 bits wide, their use (and representation) is quite different. You cannot store 3.141 in an integer, but you can in a float
.
Dissecting them both a little further:
In an integer, all bits are used to store the number value. This is (in Java and many computers too) done in the so-called two's complement. This basically means that you can represent the values of −231 to 231 − 1.
In a float, those 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa. They are laid out as follows:
S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM
There is a single bit that determines whether the number is negative or non-negative (zero is neither positive nor negative, but has the sign bit set to zero). Then there are eight bits of an exponent and 23 bits of mantissa. To get a useful number from that, (roughly) the following calculation is performed:
M × 2E
(There is more to it, but this should suffice for the purpose of this discussion)
The mantissa is in essence not much more than a 24-bit integer number. This gets multiplied by 2 to the power of the exponent part, which, roughly, is a number between −128 and 127.
Therefore you can accurately represent all numbers that would fit in a 24-bit integer but the numeric range is also much greater as larger exponents allow for larger values. For example, the maximum value for a float
is around 3.4 × 1038 whereas int
only allows values up to 2.1 × 109.
But that also means, since 32 bits only have 4.2 × 109 different states (which are all used to represent the values int
can store), that at the larger end of float
's numeric range the numbers are spaced wider apart (since there cannot be more unique float
numbers than there are unique int
numbers). You cannot represent some numbers exactly, then. For example, the number 2 × 1012 has a representation in float
of 1,999,999,991,808. That might be close to 2,000,000,000,000 but it's not exact. Likewise, adding 1 to that number does not change it because 1 is too small to make a difference in the larger scales float
is using there.
Similarly, you can also represent very small numbers (between 0 and 1) in a float
but regardless of whether the numbers are very large or very small, float
only has a precision of around 6 or 7 decimal digits. If you have large numbers those digits are at the start of the number (e.g. 4.51534 × 1035, which is nothing more than 451534 follows by 30 zeroes – and float
cannot tell anything useful about whether those 30 digits are actually zeroes or something else), for very small numbers (e.g. 3.14159 × 10−27) they are at the far end of the number, way beyond the starting digits of 0.0000...
I use an immediately invoked lambda for these scenarios:
const config = (() => {
try {
return JSON.parse(fs.readFileSync('config.json'));
} catch (error) {
return {};
}
})();
async
version:
const config = await (async () => {
try {
return JSON.parse(await fs.readFileAsync('config.json'));
} catch (error) {
return {};
}
})();
I agree with @annakata that this question needs some more clarification, but here is a very, very basic example of how to setup an onclick
event handler for the radio buttons:
<html>
<head>
<script type="text/javascript">
window.onload = function() {
var ex1 = document.getElementById('example1');
var ex2 = document.getElementById('example2');
var ex3 = document.getElementById('example3');
ex1.onclick = handler;
ex2.onclick = handler;
ex3.onclick = handler;
}
function handler() {
alert('clicked');
}
</script>
</head>
<body>
<input type="radio" name="example1" id="example1" value="Example 1" />
<label for="example1">Example 1</label>
<input type="radio" name="example2" id="example2" value="Example 2" />
<label for="example1">Example 2</label>
<input type="radio" name="example3" id="example3" value="Example 3" />
<label for="example1">Example 3</label>
</body>
</html>
According to supported databases, Oracle 11g is not officially supported. Although, I believe you shouldn't have any problems using org.hibernate.dialect.OracleDialect
.
Great! The solution given above worked for me. Had the same problem with a GET

Yeah, I know, I'm lazy, but it can be handy too.
list2 = ['%sbar' % (x,) for x in list]
And don't use list
as a name; it shadows the built-in type.
You just need to post the form data to the insert php file function, see below :)

public $db = null;

{
$this->db = new PDO("mysql:host=".$this->dbHostname.";dbname=".$this->dbDatabase, $this->dbUsername, $this->dbPassword);
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
echo "It seems there was an error. Please refresh your browser and try again. ".$e->getMessage();
}
}
public function store($email)
{
$stm = $this->db->prepare('INSERT INTO subscribers (email) VALUES ?');
$stm->bindValue(1, $email);
return $stm->execute();

2 6 2 2 2
3 7 3 3 3

All given answers work fine, but I remember learning that using setAlpha can be a bad idea performance wise (more info here). So creating a StateListDrawable is a better idea to manage disabled state of buttons. Here's how:
Create a XML btn_blue.xml in res/drawable folder:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Disable background -->
<item android:state_enabled="false"
android:color="@color/md_blue_200"/>
<!-- Enabled background -->
<item android:color="@color/md_blue_500"/>
</selector>
Create a button style in res/values/styles.xml
<style name="BlueButton" parent="ThemeOverlay.AppCompat">
<item name="colorButtonNormal">@drawable/btn_blue</item>
<item name="android:textColor">@color/md_white_1000</item>
</style>
Then apply this style to your button:
<Button
android:id="@+id/my_disabled_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/BlueButton"/>
Now when you call btnBlue.setEnabled(true)
OR btnBlue.setEnabled(false)
the state colors will automatically switch.
I experienced a similar problem: after deleting the deployment (kubectl delete deploy <name>
), the pods kept "Running" and where automatically re-created after deletion (kubectl delete po <name>
).
It turned out that the associated replica set was not deleted automatically for some reason, and after deleting that (kubectl delete rs <name>
), it was possible to delete the pods.
I had the same exception in JPA 2 using eclipse link. I had an @embedded class with one to one relationship with an entity. By mistake ,in the embedded class, i had also the annotation @Table("TRADER"). When the DB was created by the JPA from the entities it also created a table TRADER (which was a wrong as the Trader entity was embedded to the main entity) and the existence of that table was causing the above exception every time i was trying to persist my entity. After deleting the TRADER table the exception disappered.

how to have a click event outside of the dropdown menu so that it close the dropdown menu ? Heres the code
$(document).click(function (e) {
e.stopPropagation();
var container = $(".dropDown");
//check if the clicked area is dropDown or not
if (container.has(e.target).length === 0) {
$('.subMenu').hide();
}

After searching an testing alot of solution for prevent sqlmap from sql injection, in case of legacy system which cant apply prepared statments every where.
java-security-cross-site-scripting-xss-and-sql-injection topic WAS THE SOLUTION
i tried @Richard s solution but did not work in my case. i used a filter
The goal of this filter is to wrapper the request into an own-coded wrapper MyHttpRequestWrapper which transforms:
the HTTP parameters with special characters (<, >, ‘, …) into HTML codes via the org.springframework.web.util.HtmlUtils.htmlEscape(…) method. Note: There is similar classe in Apache Commons : org.apache.commons.lang.StringEscapeUtils.escapeHtml(…) the SQL injection characters (‘, “, …) via the Apache Commons classe org.apache.commons.lang.StringEscapeUtils.escapeSql(…)

db.<collection>.find({}, {field1: <value>, field2: <value> ...})
In your example, you can do something like:
db.students.find({}, {"roll":true, "_id":false})
Projection
The projection parameter determines which fields are returned in the matching documents. The projection parameter takes a document of the following form:
{ field1: <value>, field2: <value> ... }
The <value> can be any of the following:
1 or true to include the field in the return documents.
0 or false to exclude the field.
NOTE
For the _id field, you do not have to explicitly specify _id: 1 to return the _id field. The find() method always returns the _id field unless you specify _id: 0 to suppress the field.
Whenever you 'see' something in the GUI (SSMS) and you're like "that's what I need", you can always run Sql Profiler to fish for the query that was used.
Run Sql Profiler. Attach it to your database of course.
Then right click in the GUI (in SSMS) and click "Refresh".
And then go see what Profiler "catches".
I got the below when I was in MyDatabase / Security / Users and clicked "refresh" on the "Users".
Again, I didn't come up with the WHERE clause and the LEFT OUTER JOIN, it was a part of the SSMS query. And this query is something that somebody at Microsoft has written (you know, the peeps who know the product inside and out, aka, the experts), so they are familiar with all the weird "flags" in the database.
But the SSMS/GUI -> Sql Profiler tricks works in many scenarios.
SELECT
u.name AS [Name],
'Server[@Name=' + quotename(CAST(
serverproperty(N'Servername')
AS sysname),'''') + ']' + '/Database[@Name=' + quotename(db_name(),'''') + ']' + '/User[@Name=' + quotename(u.name,'''') + ']' AS [Urn],
u.create_date AS [CreateDate],
u.principal_id AS [ID],
CAST(CASE dp.state WHEN N'G' THEN 1 WHEN 'W' THEN 1 ELSE 0 END AS bit) AS [HasDBAccess]
FROM
sys.database_principals AS u
LEFT OUTER JOIN sys.database_permissions AS dp ON dp.grantee_principal_id = u.principal_id and dp.type = 'CO'
WHERE
(u.type in ('U', 'S', 'G', 'C', 'K' ,'E', 'X'))
ORDER BY
[Name] ASC
Picking 100 random points could mean that similar (or occasionally even dissimilar) images would be marked as the same, which I assume is not what you want. MD5 hashes wouldn't work if the images were different formats (png, jpeg, etc), had different sizes, or had different metadata. Reducing all images to a smaller size is a good bet, doing a pixel-for- pixel comparison shouldn't take too long as long as you're using a good image library / fast language, and the size is small enough.
You could try making them tiny, then if they are the same perform another comparison on a larger size - could be a good combination of speed and accuracy...
In order to support refactoring correctly (rename class), then you should use either:
MyClass.class.getName(); // full name with package
or (thanks to @James Van Huis):
MyClass.class.getSimpleName(); // class name and no more
you can use this one.
<div id="test"></div>
you java script code should be like that.
setInterval(function(){
$('#test').load('test.php');
},5000);
let httpParams = new HttpParams();
Object.keys(data).forEach(function (key) {
httpParams = httpParams.append(key, data[key]);
});
Since 5.0.0-beta.6 (2017-09-03) they added new feature (accept object map for HttpClient headers & params)
Going forward the object can be passed directly instead of HttpParams.
getCountries(data: any) {
// We don't need any more these lines
// let httpParams = new HttpParams();
// Object.keys(data).forEach(function (key) {
// httpParams = httpParams.append(key, data[key]);
// });
return this.httpClient.get("/api/countries", {params: data})

Do you have a local user.name
or user.email
that's overriding the global one?
git config --list --global | grep user
user.name=YOUR NAME
user.email=YOUR@EMAIL
git config --list --local | grep user
user.name=YOUR NAME
user.email=
If so, remove them
git config --unset --local user.name
git config --unset --local user.email
The local settings are per-clone, so you'll have to unset the local user.name
and user.email
for each of the repos on your machine.
a,b=[],[]
n=int(input("Provide me size of squre matrix row==column : "))
for i in range(n):
for j in range(n):
b.append(int(input()))
a.append(b)
print("Here your {} column {}".format(i+1,a))
b=[]
for m in range(n):
print(a[m])
works perfectly

}
!/^abc|mno$/ {
if (record==1) {
s = s"\n"$0
}
}
using: awk -f file.awk data

For android, I would use String android.net.Uri.encode(String s)
Encodes characters in the given string as '%'-escaped octets using the UTF-8 scheme. Leaves letters ("A-Z", "a-z"), numbers ("0-9"), and unreserved characters ("_-!.~'()*") intact. Encodes all other characters.
Ex/
String urlEncoded = "http://stackoverflow.com/search?q=" + Uri.encode(query);
Here is one more variant of how to replace all(HTML Tags | HTML Entities | Empty Space in HTML content)
content.replaceAll("(<.*?>)|(&.*?;)|([ ]{2,})", "");
where content is a String.
That's also my last problem. Here my solution I use data Model and adapter for my RecyclerView
/*Firstly, register your new data to your model*/
DataModel detail = new DataModel(id, name, sat, image);
/*after that, use set to replace old value with the new one*/
int index = 4;
mData.set(index, detail);
/*finally, refresh your adapter*/
if(adapter!=null)
adapter.notifyItemChanged(index);
try this
<TableRow
android:layout_width="match_parent"
android:layout_marginTop="5dp"
android:layout_height="wrap_content">
<View
android:layout_width="15dp"
android:layout_height="15dp"
android:background="#3fe1fa" />
<TextView
android:textSize="12dp"
android:paddingLeft="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="1700 Market Street"
android:id="@+id/textView8" />
</TableRow>

you should be able to get this problem resolved through a timeout and proxyTimeout parameter set to 600 seconds. It worked for me after battling for a while.
If I get you correctly you have just downloaded Android sdk and want to configure it working with Eclipse. I think you miss one step from the installation of the sdk:
1) you download it
2) you extract it somewhere
3) then go to the specified directory and start AndroidManager (or was it just android??). There you specify you need platform-tools and the manager will configure that for you. This will also provide you with the 'adb' executable which is crucial for the Android developement.
After that you install ADT (which I think you already did) and from Eclipse preferences -> Android options you get a place to specify where your android-sdk is. If you specify it after you did the 'step 3' you should be good to go.
I am not 100% sure I got it correctly and what your state is, so please forgive me if my comment is irrelevant. If I am wrong I will be happy to help if you provide some more details.
Something I am completely sure is that you shouldn't need to create the folder 'tools' by yourself.
PS: The description I gave is for newer versions of android sdk, but if you are encountering a problem with older version I will recommend you to start from scratch with newer version. It shouldn't take you that long time.
IEnumerable implements GetEnumerator. When called, that method will return an IEnumerator which implements MoveNext, Reset and Current.
Thus when your class implements IEnumerable, you are saying that you can call a method (GetEnumerator) and get a new object returned (an IEnumerator) you can use in a loop such as foreach.
In a nutshell:
An imperative language specfies a series of instructions that the computer executes in sequence (do this, then do that).
A declarative language declares a set of rules about what outputs should result from which inputs (eg. if you have A, then the result is B). An engine will apply these rules to inputs, and give an output.
A functional language declares a set of mathematical/logical functions which define how input is translated to output. eg. f(y) = y * y. it is a type of declarative language.
Java class final and method final -> sealed. Java member variable final -> readonly for runtime constant, const for compile time constant.
No equivalent for Local Variable final and method argument final
You can transform logical implication A => B
to NOT A or B
. This is one of the most basic laws of logic. In your case it is something like this:
SELECT *
FROM logs
WHERE pw='correct' AND (id>=800 OR success=1)
AND YEAR(timestamp)=2011
I also transformed NOT id<800
to id>=800
, which is also pretty basic.
If you're storing the object as type object
, you need to use reflection. This is true of any object type, anonymous or otherwise. On an object o, you can get its type:
Type t = o.GetType();
Then from that you look up a property:
PropertyInfo p = t.GetProperty("Foo");
Then from that you can get a value:
object v = p.GetValue(o, null);
This answer is long overdue for an update for C# 4:
dynamic d = o;
object v = d.Foo;
And now another alternative in C# 6:
object v = o?.GetType().GetProperty("Foo")?.GetValue(o, null);
Note that by using ?.
we cause the resulting v
to be null
in three different situations!
o
is null
, so there is no object at allo
is non-null
but doesn't have a property Foo
o
has a property Foo
but its real value happens to be null
.So this is not equivalent to the earlier examples, but may make sense if you want to treat all three cases the same.
find -E /path/to -regex ".*\.(jpg|gif|png|jpeg)" > log
The -E
saves you from having to escape the parens and pipes in your regex.
Agree with Sachin. Just one improvement, use connect_ex instead of connect, which can avoid try except
>>> def port_check(ip_port):
... s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
... s.settimeout(1)
... r = s.connect_ex(ip_port)
... return r == 0
...
>>> port_check(loc)
True
>>> port_check(loc_x)
False
>>> loc
('10.3.157.24', 6443)
>>>
No, because it contains items there must be an instance of it. Its items being null is irrelevant, so the statment ((arrayList) != null) == true

calendarData.set(Calendar.MILLISECOND, 0);
Calendar calendarToday = Calendar.getInstance();
calendarToday.setTimeInMillis(System.currentTimeMillis());
calendarToday.set(Calendar.HOUR_OF_DAY, 0);
calendarToday.set(Calendar.MINUTE, 0);

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.
$crud->set_relation('id','students','{first_name} {last_name}');

I used a really simple method to check a string how it's a valid JSON or not.
function testJSON(text){
if (typeof text!=="string"){
return false;
}
try{
JSON.parse(text);
return true;
}
catch (error){
return false;
}
}
Result with a valid JSON string:
var input='["foo","bar",{"foo":"bar"}]';
testJSON(input); // returns true;
Result with a simple string;
var input='This is not a JSON string.';
testJSON(input); // returns false;
Result with an object:
var input={};
testJSON(input); // returns false;
Result with null input:
var input=null;
testJSON(input); // returns false;
The last one returns false because the type of null variables is object.
This works everytime. :)

You have 2 options :
Create a third method that wrap both methods. Advantage here is that you put less logic in your template.
Otherwise if you want to add 2 calls in ng-click you can add ';' after edit($index)
like this
ng-click="edit($index); open()"
See here : http://jsfiddle.net/laguiz/ehTy6/
If you only want to process a function and not process the href it self, add the return false statement at the end of your function:
<a href="#" onclick="javascript: function() {... ; return false} return false">click</>
use jquery Every time Plugin .using this you can do ajax call for "X" time period
$("#select").everyTime(1000,function(i) {

.RefreshStyle = xlOverwriteCells

To get the first day of the month, simply get a Date
and set the current day to day 1 of the month. Clear hour, minute, second and milliseconds if you need it.
private static Date firstDayOfMonth(Date date) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.set(Calendar.DATE, 1);
return calendar.getTime();
}
First day of the week is the same thing, but using Calendar.DAY_OF_WEEK
instead
private static Date firstDayOfWeek(Date date) {
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.set(Calendar.DAY_OF_WEEK, 1);
return calendar.getTime();
}
I would just like to add that in my case rubygems
wasn't installed.
Running sudo apt-get install rubygems
solved the issue!
Here it is:
SELECT
OBJECT_NAME(f.parent_object_id) TableName,
COL_NAME(fc.parent_object_id,fc.parent_column_id) ColName
FROM
sys.foreign_keys AS f
INNER JOIN
sys.foreign_key_columns AS fc
ON f.OBJECT_ID = fc.constraint_object_id
INNER JOIN
sys.tables t
ON t.OBJECT_ID = fc.referenced_object_id
WHERE
OBJECT_NAME (f.referenced_object_id) = 'YourTableName'
This way, you'll get the referencing table and column name.
Edited to use sys.tables instead of generic sys.objects as per comment suggestion. Thanks, marc_s
This is another way. In my case I have:
Inside the button I have this code:
Image myImage = Image.FromFile(@"C:\imagenes\myImage.gif");
Bitmap croppedBitmap = new Bitmap(myImage);
croppedBitmap = croppedBitmap.Clone(
new Rectangle(
(int)LeftMargin.Value, (int)TopMargin.Value,
myImage.Width - (int)LeftMargin.Value,
myImage.Height - (int)TopMargin.Value),
System.Drawing.Imaging.PixelFormat.DontCare);
pictureBox1.Image = croppedBitmap;
I tried it in Visual studio 2012 using C#. I found this solution from this page
sendStickyBroadcast()
performs a sendBroadcast(Intent)
known as sticky, i.e. the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of registerReceiver(BroadcastReceiver, IntentFilter)
. In all other ways, this behaves the same as sendBroadcast(Intent)
. One example of a sticky broadcast sent via the operating system is ACTION_BATTERY_CHANGED
. When you call registerReceiver()
for that action -- even with a null BroadcastReceiver
-- you get the Intent that was last broadcast for that action. Hence, you can use this to find the state of the battery without necessarily registering for all future state changes in the battery.

Here's a one-line solution with mapfile:
$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "<regexp>")
Example:
$ arr=("Adam" "Bob" "Claire"$'\n'"Smith" "David" "Eve" "Fred")
$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"
Size: 6 Contents: Adam Bob Claire
Smith David Eve Fred
$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "^Claire\nSmith$")
$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"
Size: 5 Contents: Adam Bob David Eve Fred
This method allows for great flexibility by modifying/exchanging the grep command and doesn't leave any empty strings in the array.
You should override the inspect
method of your object to return the desired hash, or just implement a similar method without overriding the default object behaviour.
If you want to get fancier, you can iterate over an object's instance variables with object.instance_variables
Because async/await uses promises under the hood, you can write a little utility function like this:
export function catchEm(promise) {
return promise.then(data => [null, data])
.catch(err => [err]);
}
Then import it whenever you need to catch some errors, and wrap your async function which returns a promise with it.
import catchEm from 'utility';
async performAsyncWork() {
const [err, data] = await catchEm(asyncFunction(arg1, arg2));
if (err) {
// handle errors
} else {
// use data
}
}
You are iterating trough items in words but you have to iterate through item's length:
words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in range(len(words)):
w1 = words[i]
if w1[0] == w1[len(w1) - 1]:
c += 1
print (c)
In your case i[0] is 'aba' because i is calculated from items in words:
words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
c = 0
for i in words:
print(i)
the output is:
aba
None of the answers include the overhead size and the metadata sizes of tables.
Here is a more accurate estimation of the "disk space" allocated by a database.
SELECT ROUND((SUM(data_length+index_length+data_free) + (COUNT(*) * 300 * 1024))/1048576+150, 2) AS MegaBytes FROM information_schema.TABLES WHERE table_schema = 'DATABASE-NAME'
as mentioned above: its not possible to call a css pseudo-class / -element inline.
what i now did, is:
give your element a unique identifier, f.ex. an id or a unique class.
and write a fitting <style>
element
<style>#id29:before { content: "*";}</style>
<article id="id29">
<!-- something -->
</article>
fugly, but what inline css isnt..?
This is a bit of a religious argument, but I agree with ReSharper that you should prefer less nesting. I believe that this outweighs the negatives of having multiple return paths from a function.
The key reason for having less nesting is to improve code readability and maintainability. Remember that many other developers will need to read your code in the future, and code with less indentation is generally much easier to read.
Preconditions are a great example of where it is okay to return early at the start of the function. Why should the readability of the rest of the function be affected by the presence of a precondition check?
As for the negatives about returning multiple times from a method - debuggers are pretty powerful now, and it's very easy to find out exactly where and when a particular function is returning.
Having multiple returns in a function is not going to affect the maintainance programmer's job.
Poor code readability will.
Here is another way by using UIBezierPath (maybe it's too late ^^) Create a circle and mask UIView with it, as follows:
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
view.backgroundColor = [UIColor blueColor];
CAShapeLayer *shape = [CAShapeLayer layer];
UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:view.center radius:(view.bounds.size.width / 2) startAngle:0 endAngle:(2 * M_PI) clockwise:YES];
shape.path = path.CGPath;
view.layer.mask = shape;
Bootstrap 4 progress bar
<div class="progress">

</div>
Javascript
change progress bar on next/previous page actions
var count = Number(document.getElementById('count').innerHTML); //set this on page load in a hidden field after an ajax call
var total = document.getElementById('total').innerHTML; //set this on initial page load
var pcg = Math.floor(count/total*100);
document.getElementsByClassName('progress-bar').item(0).setAttribute('aria-valuenow',pcg);
document.getElementsByClassName('progress-bar').item(0).setAttribute('style','width:'+Number(pcg)+'%');

var offset = new Date().getTimezoneOffset();
offset
will be the interval in minutes from Local time to UTC. To get Local time from a UTC date, you would then subtract the minutes from your date.
utc_date.setMinutes(utc_date.getMinutes() - offset);
If it is one (single) branch that you need to check, for example if you want that branch 'B' is fully merged into branch 'A', you can simply do the following:
$ git checkout A
$ git branch -d B
git branch -d <branchname>
has the safety that "The branch must be fully merged in HEAD."
Caution: this actually deletes the branch B if it is merged into A.
A simple command, git checkout remote_branch_name
will help you to create a local branch that has all the changes in the remote branch.

Use Hosts Commander. It's simple and powerful. Translated description (from russian) here.
hosts add another.dev 192.168.1.1 # Remote host
hosts add test.local # 127.0.0.1 used by default
hosts set myhost.dev # new comment
hosts rem *.local
hosts enable local*
hosts disable localhost
...and many others...
Usage:
hosts - run hosts command interpreter
hosts <command> <params> - execute hosts command
Commands:
add <host> <aliases> <addr> # <comment> - add new host
set <host|mask> <addr> # <comment> - set ip and comment for host
rem <host|mask> - remove host
on <host|mask> - enable host
off <host|mask> - disable host
view [all] <mask> - display enabled and visible, or all hosts
hide <host|mask> - hide host from 'hosts view'
show <host|mask> - show host in 'hosts view'
print - display raw hosts file
format - format host rows
clean - format and remove all comments
rollback - rollback last operation
backup - backup hosts file
restore - restore hosts file from backup
recreate - empty hosts file
open - open hosts file in notepad
abs()
is for integers only. For floating point, use fabs()
(or one of the fabs()
line with the correct precision for whatever a actually is)
Do you want coordinates relative to the screen or the application?
If it's within the application just use:
Mouse.GetPosition(Application.Current.MainWindow);
If not, I believe you can add a reference to System.Windows.Forms
and use:
System.Windows.Forms.Control.MousePosition;
items[node.ind] = items[node.ind]._replace(v=node.v)
(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")
As far that I know you only can get time with Date.
Date.now is the solution but is not available everywhere : https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/now.
var currentTime = +new Date();
This gives you the current time in milliseconds.
For your jumps. If you compute interpolations correctly according to the delta frame time and you don't have some rounding number error, I bet for the garbage collector (GC).
If there is a lot of created temporary object in your loop, garbage collection has to lock the thread to make some cleanup and memory re-organization.
With Chrome you can see how much time the GC is spending in the Timeline panel.
EDIT: Since my answer, Date.now()
should be considered as the best option as it is supported everywhere and on IE >= 9.

check scheme from uri:
byte[] videoBytes;
if (uri.getScheme().equals("content")){
InputStream iStream = context.getContentResolver().openInputStream(uri);
videoBytes = getBytes(iStream);
}else{
File file = new File(uri.getPath());
FileInputStream fileInputStream = new FileInputStream(file);
videoBytes = getBytes(fileInputStream);
}
In the above answer I converted the video uri to bytes array , but that's not related to question,
I just copied my full code to show the usage of FileInputStream

I struggled with the same error code recently, due to a change in MySQL Server 5.6.20. I was able to solve the problem by changing the innodb_log_file_size in the my.ini text file.
In the release notes, it is explained that an innodb_log_file_size that is too small will trigger a "Row size too large error."
http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-20.html
You need to either have the message be a fixed size, or you need to send the size or you need to use some separator characters.
This is the easiest case for a known size (100 bytes):
in = new DataInputStream(server.getInputStream());
byte[] message = new byte[100]; // the well known size
in.readFully(message);
In this case DataInputStream
makes sense as it offers readFully()
. If you don't use it, you need to loop yourself until the expected number of bytes is read.
To reference range of cells you can use Range(Cell1,Cell2), sample:
Sub RangeTest()
Dim testRange As Range
Dim targetWorksheet As Worksheet
Set targetWorksheet = Worksheets("MySheetName")
With targetWorksheet
.Cells(5, 10).Select 'selects cell J5 on targetWorksheet
Set testRange = .Range(.Cells(5, 5), .Cells(10, 10))
End With
testRange.Select 'selects range of cells E5:J10 on targetWorksheet
End Sub
How about:
df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x
To do all these operations in one-liner:
setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))
#[1] name age gender
#<0 rows> (or 0-length row.names)
Or
data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

ObervableCollection have constructor in which you can pass your list. Quoting MSDN:

The following query works. It uses each group to do the select instead of SelectMany
. SelectMany
works on each element from each collection. For example, in your query you have a result of 2 collections. SelectMany
gets all the results, a total of 3, instead of each collection. The following code works on each IGrouping
in the select portion to get your aggregate operations working correctly.
var results = from line in Lines
group line by line.ProductCode into g
select new ResultLine {
ProductName = g.First().Name,
Price = g.Sum(pc => pc.Price).ToString(),
Quantity = g.Count().ToString(),
};
Okay, the basic difference at the machine is that double precision uses twice as many bits as single. In the usual implementation,that's 32 bits for single, 64 bits for double.
But what does that mean? If we assume the IEEE standard, then a single precision number has about 23 bits of the mantissa, and a maximum exponent of about 38; a double precision has 52 bits for the mantissa, and a maximum exponent of about 308.
The details are at Wikipedia, as usual.

There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True

In addition to Commons Lang, you can do this with Guava's method Ints.toArray(Collection<Integer> collection)
:
List<Integer> list = ...
int[] ints = Ints.toArray(list);
This saves you having to do the intermediate array conversion that the Commons Lang equivalent requires yourself.
For those saying that the answer of @kuester2000 does not work, please be aware that HTTP requests, first try to find the host IP with a DNS request and then makes the actual HTTP request to the server, so you may also need to set a timeout for the DNS request.
If your code worked without the timeout for the DNS request it's because you are able to reach a DNS server or you are hitting the Android DNS cache. By the way you can clear this cache by restarting the device.
This code extends the original answer to include a manual DNS lookup with a custom timeout:
//Our objective
String sURL = "http://www.google.com/";
int DNSTimeout = 1000;
int HTTPTimeout = 2000;
//Get the IP of the Host
URL url= null;
try {
url = ResolveHostIP(sURL,DNSTimeout);
} catch (MalformedURLException e) {
Log.d("INFO",e.getMessage());
}
if(url==null){
//the DNS lookup timed out or failed.
}
//Build the request parameters
HttpParams params = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(params, HTTPTimeout);
HttpConnectionParams.setSoTimeout(params, HTTPTimeout);
DefaultHttpClient client = new DefaultHttpClient(params);
HttpResponse httpResponse;
String text;
try {
//Execute the request (here it blocks the execution until finished or a timeout)
httpResponse = client.execute(new HttpGet(url.toString()));
} catch (IOException e) {
//If you hit this probably the connection timed out
Log.d("INFO",e.getMessage());
}
//If you get here everything went OK so check response code, body or whatever
Used method:
//Run the DNS lookup manually to be able to time it out.
public static URL ResolveHostIP (String sURL, int timeout) throws MalformedURLException {
URL url= new URL(sURL);
//Resolve the host IP on a new thread
DNSResolver dnsRes = new DNSResolver(url.getHost());
Thread t = new Thread(dnsRes);
t.start();
//Join the thread for some time
try {
t.join(timeout);
} catch (InterruptedException e) {
Log.d("DEBUG", "DNS lookup interrupted");
return null;
}
//get the IP of the host
InetAddress inetAddr = dnsRes.get();
if(inetAddr==null) {
Log.d("DEBUG", "DNS timed out.");
return null;
}
//rebuild the URL with the IP and return it
Log.d("DEBUG", "DNS solved.");
return new URL(url.getProtocol(),inetAddr.getHostAddress(),url.getPort(),url.getFile());
}

//pass in an update function that gets called when the digest is going on...
$scope.$safeApply(function() {

//pass in both a scope and a function
$scope.$safeApply($anotherScope,function() {
});
//call it on the rootScope
$rootScope.$safeApply();
$rootScope.$safeApply($rootScope);

var r = s.getRange('A:A');
var v = r.getValues();
var searchTerm = 'needle';
for(var i=v.length-1;i>=0;i--) {
if(v[0,i].toString().indexOf(searchTerm) > -1) {
// do something
}
}
};

By specifying the @JoinColumn
on both models you don't have a two way relationship. You have two one way relationships, and a very confusing mapping of it at that. You're telling both models that they "own" the IDAIRLINE column. Really only one of them actually should! The 'normal' thing is to take the @JoinColumn
off of the @OneToMany
side entirely, and instead add mappedBy to the @OneToMany
.
@OneToMany(cascade = CascadeType.ALL, mappedBy="airline")
public Set<AirlineFlight> getAirlineFlights() {
return airlineFlights;
}
That tells Hibernate "Go look over on the bean property named 'airline' on the thing I have a collection of to find the configuration."
Yes we have done this.
In your Index.cshtml you'll have something like..
<div id='gameModal' class='modal hide fade in' data-url='@Url.Action("GetGameListing")'>
<div id='gameContainer'>
</div>
</div>
<button id='showGame'>Show Game Listing</button>
Then in JS for the same page (inlined or in a separate file you'll have something like this..
$(document).ready(function() {
$('#showGame').click(function() {
var url = $('#gameModal').data('url');
$.get(url, function(data) {
$('#gameContainer').html(data);
$('#gameModal').modal('show');
});
});
});
With a method on your controller that looks like this..
[HttpGet]
public ActionResult GetGameListing()
{
var model = // do whatever you need to get your model
return PartialView(model);
}
You will of course need a view called GetGameListing.cshtml inside of your Views folder..

You can use the row_numer() over(partition by ...)
syntax like so:
select * from
(
select *
, ROW_NUMBER() OVER(PARTITION BY CName ORDER BY AddressLine) AS row
from myTable
) as a
where row = 1
What this does is that it creates a column called row
, which is a counter that increments every time it sees the same CName
, and indexes those occurrences by AddressLine
. By imposing where row = 1
, one can select the CName
whose AddressLine
comes first alphabetically. If the order by
was desc
, then it would pick the CName
whose AddressLine
comes last alphabetically.
You can use flexbox for this.
ul {
display: flex;

}

I needed something like that and the solution I gave with the help of jquery is this:
<textarea class="textlimited" data-textcounterid="counter1" maxlength="30">text</textarea>
<span class='textcounter' id="counter1"></span>
With this script:
// the selector below will catch the keyup events of elements decorated with class textlimited and have a maxlength
$('.textlimited[maxlength]').keyup(function(){
//get the fields limit
var maxLength = $(this).attr("maxlength");
// check if the limit is passed
if(this.value.length > maxLength){
return false;
}
// find the counter element by the id specified in the source input element
var counterElement = $(".textcounter#" + $(this).data("textcounterid"));
// update counter 's text
counterElement.html((maxLength - this.value.length) + " chars left");
});

Running ng serve --open after creating and going into my new project "frontend" gave this error:
After creating the project, you need to run
npm install

This piece of code is incorrect.
while 1:
(clientsocket, address) = serversocket.accept()
print ("connection found!")
data = clientsocket.recv(1024).decode()
print (data)
r='REceieve'
clientsocket.send(r.encode())
The call on accept()
on the serversocket
blocks until there's a client connection. When you first connect to the server from the client, it accepts the connection and receives data. However, when it enters the loop again, it is waiting for another connection and thus blocks as there are no other clients that are trying to connect.
That's the reason the recv
works correct only the first time. What you should do is find out how you can handle the communication with a client that has been accepted - maybe by creating a new Thread to handle communication with that client and continue accepting new clients in the loop, handling them in the same way.

You should put all your words into some kind of Collection or List and then call it like this:
var searchFor = new List<string>();
searchFor.Add("pineapple");
searchFor.Add("mango");
bool containsAnySearchString = searchFor.Any(word => compareString.Contains(word));
If you need to make a case or culture independent search you should call it like this:
bool containsAnySearchString =
searchFor.Any(word => compareString.IndexOf
(word, StringComparison.InvariantCultureIgnoreCase >= 0);
The trick is defining the masksToBounds
property of your view's layer properly:

With ES2015/ES6 you can take advantage of Object.assign
which can replace $.extend()
or _.defaults()
function myFunc(requiredArg, options = {}) {
const defaults = {
message: 'Hello',

};
const settings = Object.assign({}, defaults, options);
// do stuff
}
You can also use defaults arguments like this
function myFunc(requiredArg, { message: 'Hello', color: 'red', importance: 1 } = {}) {
// do stuff
}
Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.
The default generator for Windows seems to be set to NMAKE. Try to use:

A simple solution using fscanf
:
void read_ints (const char* file_name)
{
FILE* file = fopen (file_name, "r");
int i = 0;
fscanf (file, "%d", &i);
while (!feof (file))
{
printf ("%d ", i);
fscanf (file, "%d", &i);
}
fclose (file);
}
Alternatively to calling plt.show()
at the end of the script, you can also control each figure separately doing:
f = plt.figure(1)
plt.hist........
............
f.show()
g = plt.figure(2)
plt.hist(........
................
g.show()
raw_input()
In this case you must call raw_input
to keep the figures alive.
This way you can select dynamically which figures you want to show
Note: raw_input()
was renamed to input()

The old fashioned way of setting a global variable that persist between pages is to set the data in a Cookie. The modern way is to use Local Storage, which has a good browser support (IE8+, Firefox 3.5+, Chrome 4+, Android 2+, iPhone 2+). Using localStorage is as easy as using an array:
localStorage["key"] = value;
... in another page ...
value = localStorage["key"];
You can also attach event handlers to listen for changes, though the event API is slightly different between browsers. More on the topic.
you can stash the uncommitted changes using "git stash" then checkout to a new branch using "git checkout -b " then apply the stashed commits "git stash apply"
With C#6.0 you also have a new way of formatting date when using string interpolation e.g.
$"{DateTime.Now:yyyy-MM-dd HH:mm:ss}"
Can't say its any better, but it is slightly cleaner if including the formatted DateTime in a longer string.

Will write "${VAR_EXAMPLE}="string" in test.txt" into test.txt
This can also be used to output blocks of text to the console with the same rules by omitting the file name
#!/bin/bash
VAR_EXAMPLE="\"string\""
cat << EOF
\${VAR_EXAMPLE}=${VAR_EXAMPLE} to console
EOF
Will output "${VAR_EXAMPLE}="string" to console" to the console
The delegates:
function displayMessage(message, f)
{
f(message); // execute function "f" with variable "message"
}
function alerter(message)
{
alert(message);
}
function writer(message)
{
document.write(message);
}
Running the displayMessage function:
function runDelegate()
{
displayMessage("Hello World!", alerter); // alert message
displayMessage("Hello World!", writer); // write message to DOM
}
As already mentioned the C++ way is using stringstreams.
#include <sstream>
string a = "test";
string b = "text.txt";
string c = "text1.txt";
std::stringstream ostr;
ostr << a << " " << b << " > " << c;
Note that you can get the C string from the string stream object like so.
std::string formatted_string = ostr.str();
const char* c_str = formatted_string.c_str();
name = "John" // your variable
result = (name+" ")[:15] # this adds 15 spaces to the "name"
# but cuts it at 15 characters
As the error says, you need to make sure that your sql server is running and listening on port 1433. If server is running then you need to check whether there is some firewall rule rejecting the connection on port 1433.
Here are the commands that can be useful to troubleshoot:
netstat -a
to check whether sql server is listening on the desired porttelnet
on the host and portAnother way is to let chocolatey manage your ruby package (and any other package), that way you won't have to put ruby in your path manually:
Install chocolatey first by opening your favourite command prompt and executing:
@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
then all you need to do is type
cinst ruby
In your command prompt and the package installs.
Using a package manager provides overall more control, I'd recommend this for every package that can be installed via chocolatey.
After pip install spyder
give this command
pip install --upgrade spyder
This command will update all Spyder dependencies.
Now in command prompt(cmd) navigate to the scripts folder in your python directory. In my system the path is C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts so i use the following command in command prompt.
cd C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts
once you are inside scripts directory type spyder3 and press enter and spyder ide starts.
C:\Users\win10\AppData\Local\Programs\Python\Python36-32\Scripts>spyder3
Try this:
jQuery(document).ready(function(){
$("#special").click(function(e){
$('#status2').html(e.pageX +', '+ e.pageY);
});
})

You can use following formulas.
For Excel 2007 or later:
=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")
For Excel 2003:
=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))
Note, that
List!A:C
in VLOOKUP
and returns value from column ? 3
VLOOKUP
equals to FALSE
, in that case VLOOKUP
will only find an exact match, and the values in the first column of List!A:C
do not need to be sorted (opposite to case when you're using TRUE
).I don't validate email address format anymore (Ok I check to make sure there is an at sign and a period after that). The reason for this is what says the correctly formatted address is even their email? You should be sending them an email and asking them to click a link or verify a code. This is the only real way to validate an email address is valid and that a person is actually able to recieve email.
If you want just a command line converter, the quickest and most clean solution for me is to use csvtojson via npx (included by default in node.js)
$ npx csvtojson ./data.csv > data.json
The accepted answer is a little unclear about how to use guidelines and what the "header" is.
Steps
First add a Guideline.
Select the Guidline or move it a little bit to make the constraints visible.
Then click the round circle (the "header") until it becomes a percent. You can then drag this percentage down to 50% or whatever you want.
After that you can constrain your view to the Guideline to make it some percentage of the parent (using match_constraint
on the view).
Hiya demo http://jsfiddle.net/LYTbc/
this is a reference to the DOM element, so you can wrap it directly.
attr
api: http://api.jquery.com/attr/
The .attr() method gets the attribute value for only the first element in the matched set.
have a nice one, cheers!
code
$(document).ready(function () {
$(".inputs").click(function () {
alert(this.id);
alert(" or " + $(this).attr("id"));
});
});?
Batch files are processed row by row and terminate whenever you call an executable directly.
- To make the batch file wait for the process to terminate and continue, put call
in front of it.
- To make the batch file continue without waiting, put start ""
in front of it.
I recommend using this single line script to accomplish your goal:
@call cscript "%~dp0necdaily.vbs"
(because this is a single line, you can use @ instead of @echo off)
If you believe your script can only be called from the SysWOW64 versions of cmd.exe, you might try:
@%WINDIR%\SysWOW64\cmd.exe /c call cscript "%~dp0necdaily.vbs"
If you need the window to remain, you can replace /c with /k
Solution to allow Apache 2 to host websites outside of htdocs:
Underneath the "DocumentRoot" directive in httpd.conf, you should see a directory block. Replace this directory block with:
<Directory />
Options FollowSymLinks
AllowOverride All
Allow from all
</Directory>
REMEMBER NOT TO USE THIS CONFIGURATION IN A REAL ENVIRONMENT
The output file needs to be opened in binary mode:
f = open('varstor.txt','w')
needs to be:
f = open('varstor.txt','wb')
Collection initializers are only available in VB.NET 2010, released 2010-04-12:
Dim theVar = New List(Of String) From { "one", "two", "three" }
A very simple check you can do with Cell formulas:
Sheet 1 (new - old)
=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")
Sheet 2 (old - new)
=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")
This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)
You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".
Doe the same for Sheet two.
Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.
But two cases are not covered here:
To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com
Try the rename
command in the folder with the files:
rename 's/^/Unix_/' *
The argument of rename (sed s command) indicates to replace the regex ^ with Unix_. The caret (^) is a special character that means start of the line.
DATE: It is used for values with a date part but no time part. MySQL retrieves and displays DATE values in YYYY-MM-DD format. The supported range is 1000-01-01
to 9999-12-31
.
DATETIME: It is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format. The supported range is 1000-01-01 00:00:00
to 9999-12-31 23:59:59
.
TIMESTAMP: It is also used for values that contain both date and time parts, and includes the time zone. TIMESTAMP has a range of 1970-01-01 00:00:01
UTC to 2038-01-19 03:14:07
UTC.
TIME: Its values are in HH:MM:SS format (or HHH:MM:SS format for large hours values). TIME values may range from -838:59:59
to 838:59:59
. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).
For Files - svn revert filename
For Folders - svn revert -R folder
Most commands/programs return a 0 on success and some other value, called errorlevel
, to signal an error.
You can check for this in you batch for example by:
call <THE_COMMAND_HERE>
if %ERRORLEVEL% == 0 goto :next
echo "Errors encountered during execution. Exited with status: %errorlevel%"
goto :endofscript
:next
echo "Doing the next thing"
:endofscript
echo "Script complete"
Pycrypto has vulnerabilities assigned the CVE-2013-7459 number, and the repo hasn't accept PRs since June 23, 2014.
Pycryptodome is a drop-in replacement for the PyCrypto library, which exposes almost the same API as the old PyCrypto, see Compatibility with PyCrypto.
If you haven't install pycrypto yet, you can use pip install pycryptodome
to install pycryptodome in which you won't get Microsoft Visual C++ 14.0 issue.
you can set it in .bashrc
PATH=$PATH:/opt/ActiveTcl-8.5/bin;export PATH;
Input elements are inline by default. Add display:block
to get the margins to apply. This will, however, break the buttons onto two separate lines. Use a wrapping <div>
with text-align: center
as suggested by others to get them on the same line.
How about:
mv $(echo * | sed s:Tux.png::g) ~/Linux/New/
You have to be in the folder though.
you can use the following from the device console: pm disable com.my.app.package
which will kill it. Then use pm enable com.my.app.package
so that you can launch it again.
