Once you clear the interval using clearInterval
you could setInterval
once again. And to avoid repeating the callback externalize it as a separate function:
var ticker = function() {
console.log('idle');
};
then:
var myTimer = window.setInterval(ticker, 4000);
then when you decide to restart:
window.clearInterval(myTimer);
myTimer = window.setInterval(ticker, 4000);
If you want to set something on a timer, you can use JavaScript's setTimeout
or setInterval
methods:
setTimeout ( expression, timeout );
setInterval ( expression, interval );
Where expression
is a function and timeout
and interval
are integers in milliseconds. setTimeout
runs the timer once and runs the expression
once whereas setInterval will run the expression
every time the interval
passes.
So in your case it would work something like this:
setInterval(function() {
//call $.ajax here
}, 5000); //5 seconds
As far as the Ajax goes, see jQuery's ajax()
method. If you run an interval, there is nothing stopping you from calling the same ajax()
from other places in your code.
If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:
setInterval()
returns an integer which is the ID of the interval.
var id = setInterval(function() {
//call $.ajax here
}, 30000); // 30 seconds
If you store that ID in a variable, you can then call clearInterval(id)
which will stop the progression.
Then you can reinstantiate the setInterval()
call after you've completed your ajax form submission.
You can use it like this:
$(document).ready(function(){
setTimeout("swapImages()",1000);
function swapImages(){
var active = $('.active');
var next = ($('.active').next().length > 0) ? $('.active').next() : $('#siteNewsHead img:first');
active.removeClass('active');
next.addClass('active');
setTimeout("swapImages()",1000);
}
});
use the
setInterval(function, 60000);
EDIT : (In case if you want to stop the clock after it is started)
Script section
<script>
var int=self.setInterval(function, 60000);
</script>
and HTML Code
<!-- Stop Button -->
<a href="#" onclick="window.clearInterval(int);return false;">Stop</a>
You need to set the return value of setInterval
to a variable within the scope of the click handler, then use clearInterval()
like this:
var interval = null;
$(document).on('ready',function(){
interval = setInterval(updateDiv,3000);
});
function updateDiv(){
$.ajax({
url: 'getContent.php',
success: function(data){
$('.square').html(data);
},
error: function(){
clearInterval(interval); // stop the interval
$.playSound('oneday.wav');
$('.square').html('<span style="color:red">Connection problems</span>');
}
});
}
Use setTimeOut to stop the interval after some time.
var interVal = setInterval(function(){console.log("Running") }, 1000);
setTimeout(function (argument) {
clearInterval(interVal);
},10000);
You can use an anonymous function;
setInterval(function() { funca(10,3); },500);
I'm not sure if I'm understanding you correctly, but you could easily do something like this:
setInterval(function hello() {
console.log('world');
return hello;
}(), 5000);
There's obviously any number of ways of doing this, but that's the most concise way I can think of.
JSFiddle wraps your code in a function, so start()
is not defined in the global scope.
Moral of the story: don't use inline event bindings. Use addEventListener
/attachEvent
.
Please don't pass strings to setTimeout
and setInterval
. It's eval
in disguise.
Use a function instead, and get cozy with var
and white space:
var input = document.getElementById("input"),
add;
function start() {
add = setInterval(function() {
input.value++;
}, 1000);
}
start();

The best way to deal with audio timing is with the Web Audio Api, it has a separate clock that is accurate regardless of what is happening in the main thread. There is a great explanation, examples, etc from Chris Wilson here:
http://www.html5rocks.com/en/tutorials/audio/scheduling/
Have a look around this site for more Web Audio API, it was developed to do exactly what you are after.
Store the return of setInterval
in a variable, and use it later to clear the interval.
var timer = null;
$("textarea").blur(function(){
timer = window.setInterval(function(){ ... whatever ... }, 2000);
}).focus(function(){
if(timer){
window.clearInterval(timer);
timer = null
}
});
It is quite old question but I encountered the same issue.
If you run your web on chrome, you could read through this post Background Tabs in Chrome 57
.
Basically the interval timer could run if it haven't run out of the timer budget.
The consumption of budget is based on CPU time usage of the task inside timer.
Based on my scenario, I draw video to canvas and transport to WebRTC.
The webrtc video connection would keep updating even the tab is inactive.
However you have to use setInterval
instead of requestAnimationFrame
.
it is not recommended for UI rendering though.
It would be better to listen visibilityChange
event and change render mechenism accordingly.
Besides, you could try @kaan-soral and it should works based on the documentation.
The setInterval method returns an interval ID that you need to pass to clearInterval
in order to clear the interval. You're passing a function, which won't work. Here's an example of a working setInterval/clearInterval
var interval_id = setInterval(myMethod,500);
clearInterval(interval_id);
Just modified @ClickUpvote's answer:
You can use IIFE (Immediately Invoked Function Expression) and recursion to make it a little bit more easier:
var i = 5; //set the countdown
(function timer(){
if (--i < 0) return;
setTimeout(function(){
console.log(i + ' secs'); //do stuff here
timer();
}, 1000);
})();
var i = 5;_x000D_
(function timer(){_x000D_
if (--i < 0) return;_x000D_
setTimeout(function(){_x000D_
document.getElementsByTagName('h1')[0].innerHTML = i + ' secs';_x000D_
timer();_x000D_
}, 1000);_x000D_
})();

I like this question - inspired a little timer object in me:
window.setVariableInterval = function(callbackFunc, timing) {
var variableInterval = {
interval: timing,
callback: callbackFunc,
stopped: false,
runLoop: function() {
if (variableInterval.stopped) return;
var result = variableInterval.callback.call(variableInterval);
if (typeof result == 'number')
{
if (result === 0) return;
variableInterval.interval = result;
}
variableInterval.loop();
},
stop: function() {
this.stopped = true;
window.clearTimeout(this.timeout);
},
start: function() {
this.stopped = false;
return this.loop();
},
loop: function() {
this.timeout = window.setTimeout(this.runLoop, this.interval);
return this;
}
};
return variableInterval.start();
};
Example use
var vi = setVariableInterval(function() {
// this is the variableInterval - so we can change/get the interval here:
var interval = this.interval;
// print it for the hell of it
console.log(interval);
// we can stop ourselves.
if (interval>4000) this.stop();
// we could return a new interval after doing something
return interval + 100;
}, 100);
// we can change the interval down here too
setTimeout(function() {
vi.interval = 3500;
}, 1000);
// or tell it to start back up in a minute
setTimeout(function() {
vi.interval = 100;
vi.start();
}, 60000);
That's because you should pass a function, not a string:
function funcName() {
alert("test");
}
setInterval(funcName, 10000);
Your code has two problems:
var func = funcName();
calls the function immediately and assigns the return value."func"
is invalid even if you use the bad and deprecated eval-like syntax of setInterval. It would be setInterval("func()", 10000)
to call the function eval-like.The answer mentioned by @HaNdTriX is a great, but we are not sure if DOM is completely loaded in the below code:
var loadTime = window.performance.timing.domContentLoadedEventEnd- window.performance.timing.navigationStart;
This works perfectly when used with onload as:
window.onload = function () {
var loadTime = window.performance.timing.domContentLoadedEventEnd-window.performance.timing.navigationStart;
console.log('Page load time is '+ loadTime);
}
Edit 1: Added some context to answer
Note: loadTime
is in milliseconds, you can divide by 1000 to get seconds as mentioned by @nycynik
Yes you can. You can even test it:
var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
console.log(++i);_x000D_
if (i === 5) clearInterval(timer);_x000D_
console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);
_x000D_
In this example, this timer clears when i
reaches 5.
You can validate bobince answer by yourself when you run the following javascript or check this JSFiddle
<div id="timeout"></div>
<div id="interval"></div>
var timeout = 0;
var interval = 0;
function doTimeout(){
$('#timeout').html(timeout);
timeout++;
setTimeout(doTimeout, 1);
}
function doInterval(){
$('#interval').html(interval);
interval++;
}
$(function(){
doTimeout();
doInterval();
setInterval(doInterval, 1);
});
You could use a flag to keep track of the status:
var output = $('h1');_x000D_
var isPaused = false;_x000D_
var time = 0;_x000D_
var t = window.setInterval(function() {_x000D_
if(!isPaused) {_x000D_

output.text("Seconds: " + time);_x000D_
}_x000D_

This is just what I would do, I'm not sure if you can actually pause the setInterval.
Note: This system is easy and works pretty well for applications that don't require a high level of precision, but it won't consider the time elapsed in between ticks: if you click pause after half a second and later click play your time will be off by half a second.

You can use strtok
to get string before first occurence of ?
$url = strtok($_SERVER["REQUEST_URI"], '?');
strtok()
represents the most concise technique to directly extract the substring before the ?
in the querystring. explode()
is less direct because it must produce a potentially two-element array by which the first element must be accessed.
Some other techniques may break when the querystring is missing or potentially mutate other/unintended substrings in the url -- these techniques should be avoided.
$urls = [
'www.example.com/myurl.html?unwantedthngs#hastag',
'www.example.com/myurl.html'
];
foreach ($urls as $url) {
var_export(['strtok: ', strtok($url, '?')]);
echo "\n";
var_export(['strstr/true: ', strstr($url, '?', true)]); // not reliable
echo "\n";
var_export(['explode/2: ', explode('?', $url, 2)[0]]); // limit allows func to stop searching after first encounter
echo "\n";
var_export(['substr/strrpos: ', substr($url, 0, strrpos( $url, "?"))]); // not reliable; still not with strpos()
echo "\n---\n";
}
Output:
array (
0 => 'strtok: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'strstr/true: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'explode/2: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'substr/strrpos: ',
1 => 'www.example.com/myurl.html',
)

Logcollector is a good option but you need to install it first.
When I want to get the logfile to send by mail, I usually do the following:
adb shell logcat > log.txt
For Ionic, try this:
ionic cordova plugin add cordova-plugin-androidx
ionic cordova plugin add cordova-plugin-androidx-adapter
The error comes because this app is not using androidX but these plugins solve errors.
Building on the installation concept of chocolatey
and the idea suggested by @Tracker, what worked for me was to do the following and all users on windows were then happy working with nodejs
and npm
.
Choose C:\ProgramData\nodejs
as installation directory for nodejs
and install nodejs
with any user that is a member of the administrator group.
This can be done with chocolatey as: choco install nodejs.install -ia "'INSTALLDIR=C:\ProgramData\nodejs'"
Then create a folder called npm-cache
at the root of the installation directory, which after following above would be C:\ProgramData\nodejs\npm-cache
.
Create a folder called etc
at the root of the installation directory, which after following above would be C:\ProgramData\nodejs\etc
.
Set NODE
environment variable as C:\ProgramData\nodejs
.
Set NODE_PATH
environment variable as C:\ProgramData\nodejs\node_modules
.
Ensure %NODE%
environment variable previously created above is added (or its path) is added to %PATH%
environment variable.
Edit %NODE_PATH%\npm\npmrc
with the following content prefix=C:\ProgramData\nodejs
From command prompt, set the global config like so...
npm config --global set prefix "C:\ProgramData\nodejs"
npm config --global set cache "C:\ProgramData\nodejs\npm-cache"
It is important the steps above are carried out preferably in sequence and before updating npm (npm -g install npm@latest
) or attempting to install any npm
module.
Performing the above steps helped us running nodejs
as system wide installation, easily available to all users with proper permissions. Each user can then run node
and npm
as required.

Yes.
window.screen.availHeight
window.screen.availWidth
update 2017-11-10
From Tsunamis in the comments:
To get the native resolution of i.e. a mobile device you have to multiply with the device pixel ratio:
window.screen.width * window.devicePixelRatio
andwindow.screen.height * window.devicePixelRatio
. This will also work on desktops, which will have a ratio of 1.
And from Ben in another answer:
In vanilla JavaScript, this will give you the AVAILABLE width/height:
window.screen.availHeight window.screen.availWidth
For the absolute width/height, use:
window.screen.height window.screen.width
Both of your examples should behave pretty much the same.
A value returned inside a then()
handler becomes the resolution value of the promise returned from that then()
. If the value returned inside the .then
is a promise, the promise returned by then()
will "adopt the state" of that promise and resolve/reject just as the returned promise does.
In your first example, you return "bbb"
in the first then()
handler, so "bbb"
is passed into the next then()
handler.
In your second example, you return a promise that is immediately resolved with the value "bbb"
, so "bbb"
is passed into the next then()
handler. (The Promise.resolve()
here is extraneous).
The outcome is the same.
If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.
The other answers are correct, but if you are trying to make a list of functions, each with a different parameter, that can be executed later, the following code will do that:
import functools
a = [functools.partial(lambda x: x*x, x) for x in range(10)]
b = []
for i in a:
b.append(i())
In [26]: b
Out[26]: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
While the example is contrived, I found it useful when I wanted a list of functions that each print something different, i.e.
import functools
a = [functools.partial(lambda x: print(x), x) for x in range(10)]
for i in a:
i()
You need to tell scp
where to send the file. In your command that is not working:
scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~
You have not mentioned a remote server. scp
uses :
to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c
from the host C
to your local home directory.
The correct upload command, based on your comments, should be something like:
C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:
If you are running the command from your home directory, you can use a relative path:
C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:
You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:
C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/
Define a helper function like this
function checkWhitespace(inputString){
let stringArray = inputString.split(' ');
let output = true;
for (let el of stringArray){
if (el!=''){
output=false;
}
}
return output;
}
Then check your input field value by passing through as an argument. If function returns true, that means value is only white space.
As an example
let inputValue = $('#firstName').val();
if(checkWhitespace(inputValue)) {
// Show Warnings or return warnings
}else {
// // Block of code-probably store input value into database
}

Alternatively, cv2.merge()
can be used to turn a single channel binary mask layer into a three channel color image by merging the same layer together as the blue, green, and red layers of the new image. We pass in a list of the three color channel layers - all the same in this case - and the function returns a single image with those color channels. This effectively transforms a grayscale image of shape (height, width, 1)
into (height, width, 3)
To address your problem
I did some thresholding on an image and want to label the contours in green, but they aren't showing up in green because my image is in black and white.
This is because you're trying to display three channels on a single channel image. To fix this, you can simply merge the three single channels
image = cv2.imread('image.png')
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
gray_three = cv2.merge([gray,gray,gray])
Example
We create a color image with dimensions (200,200,3)
image = (np.random.standard_normal([200,200,3]) * 255).astype(np.uint8)
Next we convert it to grayscale and create another image using cv2.merge()
with three gray channels
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
gray_three = cv2.merge([gray,gray,gray])
We now draw a filled contour onto the single channel grayscale image (left) with shape (200,200,1)
and the three channel grayscale image with shape (200,200,3)
(right). The left image showcases the problem you're experiencing since you're trying to display three channels on a single channel image. After merging the grayscale image into three channels, we can now apply color onto the image
contour = np.array([[10,10], [190, 10], [190, 80], [10, 80]])
cv2.fillPoly(gray, [contour], [36,255,12])
cv2.fillPoly(gray_three, [contour], [36,255,12])
Full code
import cv2
import numpy as np
# Create random color image
image = (np.random.standard_normal([200,200,3]) * 255).astype(np.uint8)
# Convert to grayscale (1 channel)
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
# Merge channels to create color image (3 channels)
gray_three = cv2.merge([gray,gray,gray])
# Fill a contour on both the single channel and three channel image
contour = np.array([[10,10], [190, 10], [190, 80], [10, 80]])
cv2.fillPoly(gray, [contour], [36,255,12])
cv2.fillPoly(gray_three, [contour], [36,255,12])
cv2.imshow('image', image)
cv2.imshow('gray', gray)
cv2.imshow('gray_three', gray_three)

Try to avoid using null
in Scala. It's really there only for interoperability with Java. In Scala, use Option
for things that might be empty. If you're calling a Java API method that might return null
, wrap it in an Option
immediately.
def getObject : Option[QueueObject] = {
// Wrap the Java result in an Option (this will become a Some or a None)
Option(someJavaObject.getResponse)
}
Note: You don't need to put it in a val
or use an explicit
return
statement in Scala; the result will be the value of
the last expression in the block (in fact, since there's only one statement, you don't even need a block).
def getObject : Option[QueueObject] = Option(someJavaObject.getResponse)
Besides what the others have already shown (for example calling foreach
on the Option
, which might be slightly confusing), you could also call map
on it (and ignore the result of the map operation if you don't need it):
getObject map QueueManager.add
This will do nothing if the Option
is a None
, and call QueueManager.add
if it is a Some
.
I find using a regular if
however clearer and simpler than using any of these "tricks" just to avoid an indentation level. You could also just write it on one line:
if (getObject.isDefined) QueueManager.add(getObject.get)
or, if you want to deal with null
instead of using Option
:
if (getObject != null) QueueManager.add(getObject)
edit - Ben is right, be careful to not call getObject
more than once if it has side-effects; better write it like this:
val result = getObject
if (result.isDefined) QueueManager.add(result.get)
or:
val result = getObject
if (result != null) QueueManager.add(result)
The following works for me:
DEPS := $(OBJS:.o=.d)
-include $(DEPS)
%.o: %.cpp
$(CXX) $(CFLAGS) -MMD -c -o $@ $<
What about normal encoded white-space character?
 
os.system()
returns the (encoded) process exit value. 0
means success:
On Unix, the return value is the exit status of the process encoded in the format specified for
wait()
. Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.
The output you see is written to stdout
, so your console or terminal, and not returned to the Python caller.
If you wanted to capture stdout
, use subprocess.check_output()
instead:
x = subprocess.check_output(['whoami'])
Convert.ToString(object)
converts to string. If the object is null
, Convert.ToString
converts it to an empty string.
Calling .ToString()
on an object with a null value throws a System.NullReferenceException
.
EDIT:
Two exceptions to the rules:
1) ConvertToString(string)
on a null string will always return null.
2) ToString(Nullable<T>)
on a null value will return "" .
Code Sample:
// 1) Objects:
object obj = null;
//string valX1 = obj.ToString(); // throws System.NullReferenceException !!!
string val1 = Convert.ToString(obj);
Console.WriteLine(val1 == ""); // True
Console.WriteLine(val1 == null); // False
// 2) Strings
String str = null;
//string valX2 = str.ToString(); // throws System.NullReferenceException !!!
string val2 = Convert.ToString(str);
Console.WriteLine(val2 == ""); // False
Console.WriteLine(val2 == null); // True
// 3) Nullable types:
long? num = null;
string val3 = num.ToString(); // ok, no error
Console.WriteLine(num == null); // True
Console.WriteLine(val3 == ""); // True
Console.WriteLine(val3 == null); // False
val3 = Convert.ToString(num);
Console.WriteLine(num == null); // True
Console.WriteLine(val3 == ""); // True
Console.WriteLine(val3 == null); // False
Voila!

Here is an answer using object-scan.
When accessing a single entry, this answer doesn't really provide much benefit over vanilla javascript. However interacting with multiple fields at the same time this answer can be more performant.
Here is how you could interact with a single field
// const objectScan = require('object-scan');
const data = { code: 42, items: [{ id: 1, name: 'foo' }, { id: 2, name: 'bar' }] };
const get = (haystack, needle) => objectScan([needle], {
abort: true,
rtn: 'value'
})(haystack);
const set = (haystack, needle, value) => objectScan([needle], {
abort: true,
rtn: 'bool',
filterFn: ({ parent, property }) => {
parent[property] = value;
return true;
}
})(haystack);
console.log(get(data, 'items[1].name'));
// => bar
console.log(set(data, 'items[1].name', 'foo2'));
// => true
console.log(data);
// => { code: 42, items: [ { id: 1, name: 'foo' }, { id: 2, name: 'foo2' } ] }

And here is how one could find an entity in a deeply nested object searching by id (as asked in comment)
// const objectScan = require('object-scan');
const myData = { code: 42, items: [{ id: 1, name: 'aaa', items: [{ id: 3, name: 'ccc' }, { id: 4, name: 'ddd' }] }, { id: 2, name: 'bbb', items: [{ id: 5, name: 'eee' }, { id: 6, name: 'fff' }] }] };
const findItemById = (haystack, id) => objectScan(['**(^items$).id'], {
abort: true,
useArraySelector: false,
rtn: 'parent',
filterFn: ({ value }) => value === id
})(haystack);
console.log(findItemById(myData, 5));

If I'm not mistaken it is:
MyArray.SetValue(ArrayElement, PositionInArray)
For Linq to work over Dictionary
you need at least .Net v3.5 and using System.Linq;
.
Some alternatives:
string myDesiredOutput = string.Join(";", myDict.Select(x => string.Join("=", x.Key, x.Value)));
or
string myDesiredOutput = string.Join(";", myDict.Select(x => $"{x.Key}={x.Value}"));
If you can't use Linq for some reason, use Stringbuilder
:
StringBuilder sb = new StringBuilder();
var isFirst = true;
foreach(var x in myDict)
{
if (isFirst)
{
sb.Append($"{x.Key}={x.Value}");
isFirst = false;
}
else
sb.Append($";{x.Key}={x.Value}");
}
string myDesiredOutput = sb.ToString();
myDesiredOutput:
A=1;B=2;C=3;D=4
Assuming that you would really want your loop to run 24/7 as a background service
For a solution that doesn't involve injecting your code with libraries, you can simply create a service template, since you are using linux:
[Unit]
Description = <Your service description here>
After = network.target # Assuming you want to start after network interfaces are made available
[Service]
Type = simple
ExecStart = python <Path of the script you want to run>
User = # User to run the script as
Group = # Group to run the script as
Restart = on-failure # Restart when there are errors
SyslogIdentifier = <Name of logs for the service>
RestartSec = 5
TimeoutStartSec = infinity
[Install]
WantedBy = multi-user.target # Make it accessible to other users
Place that file in your daemon service folder (usually /etc/systemd/system/
), in a *.service
file, and install it using the following systemctl commands (will likely require sudo privileges):
systemctl enable <service file name without .service extension>
systemctl daemon-reload
systemctl start <service file name without .service extension>
You can then check that your service is running by using the command:
systemctl | grep running

Node.js
itself offers an HTTP module, whose createServer method returns an object that you can use to respond to HTTP requests. That object inherits the http.Server
prototype.
I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

Don't do this! You're opening your machine to attacks. Instead run a local server. It's as easy as opening a shell/terminal/commandline and typing
cd path/to/files
python -m SimpleHTTPServer
Then pointing your browser to
http://localhost:8000
If you find it's too slow consider this solution
jsPDF is able to use plugins. In order to enable it to print HTML, you have to include certain plugins and therefore have to do the following:
If you want to ignore certain elements, you have to mark them with an ID, which you can then ignore in a special element handler of jsPDF. Therefore your HTML should look like this:
<!DOCTYPE html>
<html>
<body>
<p id="ignorePDF">don't print this to pdf</p>
<div>
<p><font size="3" color="red">print this to pdf</font></p>
</div>
</body>
</html>
Then you use the following JavaScript code to open the created PDF in a PopUp:
var doc = new jsPDF();
var elementHandler = {
'#ignorePDF': function (element, renderer) {
return true;
}
};
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(
source,
15,
15,
{
'width': 180,'elementHandlers': elementHandler
});
doc.output("dataurlnewwindow");
For me this created a nice and tidy PDF that only included the line 'print this to pdf'.
Please note that the special element handlers only deal with IDs in the current version, which is also stated in a GitHub Issue. It states:
Because the matching is done against every element in the node tree, my desire was to make it as fast as possible. In that case, it meant "Only element IDs are matched" The element IDs are still done in jQuery style "#id", but it does not mean that all jQuery selectors are supported.
Therefore replacing '#ignorePDF' with class selectors like '.ignorePDF' did not work for me. Instead you will have to add the same handler for each and every element, which you want to ignore like:
var elementHandler = {
'#ignoreElement': function (element, renderer) {
return true;
},
'#anotherIdToBeIgnored': function (element, renderer) {
return true;
}
};
From the examples it is also stated that it is possible to select tags like 'a' or 'li'. That might be a little bit to unrestrictive for the most usecases though:
We support special element handlers. Register them with jQuery-style ID selector for either ID or node name. ("#iAmID", "div", "span" etc.) There is no support for any other type of selectors (class, of compound) at this time.
One very important thing to add is that you lose all your style information (CSS). Luckily jsPDF is able to nicely format h1, h2, h3 etc., which was enough for my purposes. Additionally it will only print text within text nodes, which means that it will not print the values of textareas and the like. Example:
<body>
<ul>
<!-- This is printed as the element contains a textnode -->
<li>Print me!</li>
</ul>
<div>
<!-- This is not printed because jsPDF doesn't deal with the value attribute -->
<input type="textarea" value="Please print me, too!">
</div>
</body>

Alternative solution based on the OP's own solution by utilizing an enum
. Additionally, a parser and round-trip tests are included.

public final String symbol = name();
public final int maxArity;
private Digit(int value, int maxArity) {
this.value = value;
this.maxArity = maxArity;
}
}
private static final Digit[] DIGITS = Digit.values();
public static String of(int number) {
if (number < 1 || 3999 < number) {
throw new IllegalArgumentException(String.format(
"Roman numbers are only defined for numbers between 1 and 3999 (%d was given)",
number
));
}
StringBuilder sb = new StringBuilder();
for (Digit digit : DIGITS) {
int value = digit.value;
String symbol = digit.symbol;
while (number >= value) {
sb.append(symbol);
number -= value;
}
}
return sb.toString();
}
public static int parse(String roman) {
if (roman.isEmpty()) {
throw new NumberFormatException("The empty string does not comprise a valid Roman number");
}
int number = 0;
int offset = 0;
for (Digit digit : DIGITS) {
int value = digit.value;
int maxArity = digit.maxArity;
String symbol = digit.symbol;
for (int i = 0; i < maxArity && roman.startsWith(symbol, offset); i++) {
number += value;
offset += symbol.length();
}
}
if (offset != roman.length()) {
throw new NumberFormatException(String.format(
"The string '%s' does not comprise a valid Roman number",
roman
));
}
return number;
}
/** TESTS */
public static void main(String[] args) {
/* Demonstrating round-trip for all possible inputs. */
for (int number = 1; number <= 3999; number++) {
String roman = of(number);
int parsed = parse(roman);
if (parsed != number) {
System.err.format(
"ERROR: number: %d, roman: %s, parsed: %d\n",
number,

If you have trouble in Xcode 12 with simulators, not real device, yes you have to remove VALID_ARCHS settings because it's not supported anymore. Go to "builds settings", search "VALID_ARCHS" and remove the user-defined properties. Do it in every target you have.
Still, you may need to add a script at the bottom of your podfile to have pods compiling with the right architecture and deployment target :
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
end
end
end
In the simplest terms:
--soft
: uncommit changes, changes are left staged (index).--mixed
(default): uncommit + unstage changes, changes are left in working tree.--hard
: uncommit + unstage + delete changes, nothing left.Now on the Smartgit webpage (I don't know since when) there is the possibility to download directly the .deb package. Once installed, it will upgrade automagically itself when a new version is released.
Python has control flow statements instead of goto
statements. One implementation of control flow is Python's while
loop. You can give it a boolean condition (boolean values are either True or False in Python), and the loop will execute repeatedly until that condition becomes false. If you want to loop forever, all you have to do is start an infinite loop.
Be careful if you decide to run the following example code. Press Control+C in your shell while it is running if you ever want to kill the process. Note that the process must be in the foreground for this to work.
while True:
# do stuff here
pass
The line # do stuff here
is just a comment. It doesn't execute anything. pass
is just a placeholder in python that basically says "Hi, I'm a line of code, but skip me because I don't do anything."
Now let's say you want to repeatedly ask the user for input forever and ever, and only exit the program if the user inputs the character 'q' for quit.
You could do something like this:
while True:
cmd = raw_input('Do you want to quit? Enter \'q\'!')
if cmd == 'q':
break
cmd
will just store whatever the user inputs (the user will be prompted to type something and hit enter). If cmd
stores just the letter 'q', the code will forcefully break
out of its enclosing loop. The break
statement lets you escape any kind of loop. Even an infinite one! It is extremely useful to learn if you ever want to program user applications which often run on infinite loops. If the user does not type exactly the letter 'q', the user will just be prompted repeatedly and infinitely until the process is forcefully killed or the user decides that he's had enough of this annoying program and just wants to quit.
You must get directory right path of program(node.js in program files).
such as
and use "npm install -g phonegap"
Position the cursor inside the class, then press ALT + Ins and select Getters and Setters

}
static var preferredLanguageCodes: [String] {

}

The trick is to force the inner query return only one record by adding an aggregate function (I have used max() here). This will work perfectly as far as the query is concerned, but, honestly, OP should investigate why the inner query is returning multiple records by examining the data. Are these multiple records really relevant business wise?
If you are using .NET framework 4.5 you can use System.Net.WebUtility.HtmlDecode() which takes a HTML encoded string and returns a decoded string.
Documented on MSDN at: http://msdn.microsoft.com/en-us/library/system.net.webutility.htmldecode(v=vs.110).aspx
You can use this in a Windows Store app as well.
All of the answers are way too complicated. OP requested a way to do this from CMD.
Here you go (from cmd file):
powershell.exe /c "$(New-Object -ComObject Shell.Application).NameSpace(0xA).Items() | %%{Remove-Item $_.Path -Recurse -Confirm:$false"
And yes, it will update in explorer.
You can use np.clip()
to achieve the same:
a = [1, 3, 5, 6, 9, 10, 14, 15, 56]
np.clip(a,6,10)
However, it holds the values less than and greater than 6 and 10 respectively.
If just want to use Linq, you can override Equals and GetHashCode methods.
Product class:
public class Product
{
public string ProductName { get; set; }
public int Id { get; set; }
public override bool Equals(object obj)
{
if (!(obj is Product))
{
return false;
}
var other = (Product)obj;
return Id == other.Id;
}
public override int GetHashCode()
{
return Id.GetHashCode();
}
}
Main Method:
static void Main(string[] args)
{
var products = new List<Product>
{
new Product{ ProductName="Product 1",Id = 1},
new Product{ ProductName="Product 2",Id = 2},
new Product{ ProductName="Product 4",Id = 5},
new Product{ ProductName="Product 3",Id = 3},
new Product{ ProductName="Product 4",Id = 4},
new Product{ ProductName="Product 6",Id = 4},
new Product{ ProductName="Product 6",Id = 4},
};
var itemsDistinctByProductName = products.Distinct().ToList();
foreach (var product in itemsDistinctByProductName)
{
Console.WriteLine($"Product Id : {product.Id} ProductName : {product.ProductName} ");
}
Console.ReadKey();
}

I don't know what version of CI you were using back in 2013, but I am using CI3 and I just tested with two null
parameters passed to limit()
and there was no LIMIT
or OFFSET
in the rendered query (I checked by using get_compiled_select()
).
This means that -- assuming your have correctly posted your coding attempt -- you don't need to change anything (or at least the old issue is no longer a CI issue).
If this was my project, this is how I would write the method to return an indexed array of objects or an empty array if there are no qualifying rows in the result set.
function nationList($limit = null, $start = null) {
// assuming the language value is sanitized/validated/whitelisted
return $this->db
->select('nation.id, nation.name_' . $this->session->userdata('language') . ' AS name')
->from('nation')
->order_by("name")
->limit($limit, $start)
->get()
->result();
}
These refinements remove unnecessary syntax, conditions, and the redundant loop.
For reference, here is the CI core code:
/**
* LIMIT
*
* @param int $value LIMIT value
* @param int $offset OFFSET value
* @return CI_DB_query_builder
*/
public function limit($value, $offset = 0)
{
is_null($value) OR $this->qb_limit = (int) $value;
empty($offset) OR $this->qb_offset = (int) $offset;
return $this;
}
So the $this->qb_limit
and $this->qb_offset
class objects are not updated because null
evaluates as true
when fed to is_null()
or empty()
.
public async Task<bool> Update(MyObject item)

You can do this by providing in class numbers
:
By the way, there is a strong convention that Java class names are uppercased.
Case 1 (simple getter):
public class Numbers {
private List<Integer> list;
public List<Integer> getList() { return list; }
...
}
Case 2 (non-modifiable wrapper):
public class Numbers {
private List<Integer> list;
public List<Integer> getList() { return Collections.unmodifiableList( list ); }
...
}
Case 3 (specific methods):
public class Numbers {
private List<Integer> list;
public void addToList( int i ) { list.add(i); }
public int getValueAtIndex( int index ) { return list.get( index ); }
...
}

else if(result==NSOrderedDescending)
NSLog(@"Date1 is in the past");
else
NSLog(@"Both dates are the same");

The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").
var str = 'a b c';
var replaced = str.replace(/\s/g, '+');
it simple, select columns want to insert primary key and click on Key icon on header and save table
happy coding..,
One important distinction between the two (which is visible in the Reflected code) is that SelectedValue will return an empty string if a nothing is selected, whereas SelectedItem.Value will throw a NullReference exception.
I don't know if you fixed it, but I did had the same issue, finally it was a dumb thing, I had:
<script src="jquery-ui/jquery-ui.min.css" rel="stylesheet">
but it should be:
<link href="jquery-ui/jquery-ui.min.css" rel="stylesheet">
Just change <scrip>
to <link>
and src
to href
double value = 3.4555;
String value1 = String.format("% .3f", value) ;
String value2 = value1.substring(0, value1.length() - 1);
System.out.println(value2);
double doublevalue= Double.valueOf(value2);
System.out.println(doublevalue);
And, just to throw it in the mix, is the oft-forgotten str.translate
which will work a lot faster than looping/regular expressions:
For Python 2:
from string import digits
s = 'abc123def456ghi789zero0'
res = s.translate(None, digits)
# 'abcdefghizero'
For Python 3:
from string import digits
s = 'abc123def456ghi789zero0'
remove_digits = str.maketrans('', '', digits)
res = s.translate(remove_digits)
# 'abcdefghizero'
Try this
System.Net.WebUtility.HtmlDecode(string);
System.Net.WebUtility.HtmlEncode(string);
MacOS 10.15: Android Studio 3.5.1:
The solution that works for me was to use the Java Environment tool jenv
(installed via homebrew). This tool changes the $JAVA_HOME when one switches between java versions.
In my case I have multiple Java versions installed and the current global version in use was the default. I also found it necessary to comment out the $JAVA_HOME environment variable in my .bash_profile
when using this tool.
In Terminal, I entered jenv global 1.8
to get java 1.8 running instead of a later version (I have multiple versions installed).
After that:
flutter doctor --android-licenses
OR
sdkmanager --licenses
both work fine.
Note: You may need to exit and reopen your Terminal shell if you have to redefine the $JAVA_HOME environment variable.
Here is a solution through list comprehension. cols is the list of columns to get index for:
[df.columns.get_loc(c) for c in cols if c in df]
Load the multicol package, like this \usepackage{multicol}
. Then use:
\begin{multicols}{2}
Column 1
\columnbreak
Column 2
\end{multicols}
If you omit the \columnbreak
, the columns will balance automatically.
Warning, Chrome (and other browsers) will complain that multiple ACAO headers are set if you follow some of the other answers.
The error will be something like XMLHttpRequest cannot load ____. The 'Access-Control-Allow-Origin' header contains multiple values '____, ____, ____', but only one is allowed. Origin '____' is therefore not allowed access.
Try this:
$http_origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = array(
'http://domain1.com',
'http://domain2.com',
);
if (in_array($http_origin, $allowed_domains))
{
header("Access-Control-Allow-Origin: $http_origin");
}
First of all you should update to Android Studio Source: https://code.google.com/p/android/issues/detail?id=77983
Then you should go to File -> Invalidate Caches / Restart -> Invalidate Caches & Restart.
Then try to build the application again.

You can run from Java code.
try {
File file = new File(keystore location);
InputStream is = new FileInputStream(file);
KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
String password = "password";
keystore.load(is, password.toCharArray());
Enumeration<String> enumeration = keystore.aliases();
while(enumeration.hasMoreElements()) {
String alias = enumeration.nextElement();
System.out.println("alias name: " + alias);
Certificate certificate = keystore.getCertificate(alias);
System.out.println(certificate.toString());
}
} catch (java.security.cert.CertificateException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (KeyStoreException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally {
if(null != is)
try {
is.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Certificate class holds all information about the keystore.
UPDATE- OBTAIN PRIVATE KEY
Key key = keyStore.getKey(alias, password.toCharArray());
String encodedKey = new Base64Encoder().encode(key.getEncoded());
System.out.println("key ? " + encodedKey);

This usually occurs when your current directory does not exist anymore. Most likely, from another terminal you remove that directory (from within a script or whatever). To get rid of this, in case your current directory was recreated in the meantime, just cd
to another (existing) directory and then cd
back; the simplest would be: cd; cd -
.
urllib.request should work. Just set it up in a while(not done) loop, check if a localfile already exists, if it does send a GET with a RANGE header, specifying how far you got in downloading the localfile. Be sure to use read() to append to the localfile until an error occurs.
This is also potentially a duplicate of Python urllib2 resume download doesn't work when network reconnects
(I'm not allowed to comment yet.) I would suggest the following improvements to the already great answer of James McNellis:
template <typename Enumeration>
constexpr auto as_integer(Enumeration const value)
-> typename std::underlying_type<Enumeration>::type
{
static_assert(std::is_enum<Enumeration>::value, "parameter is not of type enum or enum class");
return static_cast<typename std::underlying_type<Enumeration>::type>(value);
}
with
constexpr
: allowing me to use an enum member value as compile-time array sizestatic_assert
+is_enum
: to 'ensure' compile-time that the function does sth. with enumerations only, as suggestedBy the way I'm asking myself: Why should I ever use enum class
when I would like to assign number values to my enum members?! Considering the conversion effort.
Perhaps I would then go back to ordinary enum
as I suggested here: How to use enums as flags in C++?
Yet another (better) flavor of it without static_assert, based on a suggestion of @TobySpeight:
template <typename Enumeration>
constexpr std::enable_if_t<std::is_enum<Enumeration>::value,
std::underlying_type_t<Enumeration>> as_number(const Enumeration value)
{
return static_cast<std::underlying_type_t<Enumeration>>(value);
}
that will do it all without css

In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).
Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.
# reassign depth values under 10 to zero
df$depth[df$depth<10] <- 0
(For the columns that are factors, you can only assign values that are factor levels. If you wanted to assign a value that wasn't currently a factor level, you would need to create the additional level first:
levels(df$species) <- c(levels(df$species), "unknown")
df$species[df$depth<10] <- "unknown"
This is how to retrieve a Column Name from a DataColumn:
MyDataTable.Columns(1).ColumnName
To get the name of all DataColumns within your DataTable:
Dim name(DT.Columns.Count) As String
Dim i As Integer = 0
For Each column As DataColumn In DT.Columns
name(i) = column.ColumnName
i += 1

Another tricky solution is to name elements of list and attach
it:
list_name = list(
head(iris),
head(swiss),
head(airquality)
)
names(list_name) <- paste("orca", seq_along(list_name), sep="")
attach(list_name)

# 3 4.7 3.2 1.3 0.2 setosa
# 4 4.6 3.1 1.5 0.2 setosa
# 5 5.0 3.6 1.4 0.2 setosa
# 6 5.4 3.9 1.7 0.4 setosa
Try to set the property when starting JVM, for example, add -Djava.net.preferIPv4Stack=true
.
You can't set it when code running, as the java.net just read it when jvm starting.
And about the root cause, this article give some hint: Why do I need java.net.preferIPv4Stack=true only on some windows 7 systems?.
When the pod is recreating automatically even after the deletion of the pod manually, then those pods have been created using the Deployment. When you create a deployment, it automatically creates ReplicaSet and Pods. Depending upon how many replicas of your pod you mentioned in the deployment script, it will create those number of pods initially. When you try to delete any pod manually, it will automatically create those pod again.
Yes, sometimes you need to delete the pods with force. But in this case force command doesn’t work.
You can't do this without JavaScript. Stackoverflow is using the jQuery JavaScript library which attachs functions to HTML elements on page load.
Here's how you could do it with vanilla JavaScript:
<textarea onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>
Keycode 13 is the enter key.
Here's how you could do it with jQuery like as Stackoverflow does:
<textarea class="commentarea"></textarea>
with
$(document).ready(function() {
$('.commentarea').keydown(function(event) {
if (event.which == 13) {
this.form.submit();
event.preventDefault();
}
});
});
you have to iterate gridview Rows
for (int count = 0; count < grd.Rows.Count; count++)
{
if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
{
((Label)grd.Rows[count].FindControl("labelID")).Text
}
}
I have tried all above answers it's showing me same vertically recycler view, so I have tried another example.
Initialize the adapter
private Adapter mAdapter;
set the adapter like this
mAdapter = new Adapter();
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
recycler_view.setLayoutManager(linearLayoutManager);
recycler_view.setAdapter(mAdapter);
Hope this will also work for you For Complete code please refer this link
A slightly more readable alternative solution:
sys.stdout.write(code.ljust(5) + name.ljust(20) + industry)
Note that ljust(#ofchars)
uses fixed width characters and doesn't dynamically adjust like the other solutions.
using jquery you can use
this.$('select#myid').append('<option>newvalue</option>');
where "myid" is the id of the dropdown list and newvalue is the text that you want to insert..
file_exists checks whether a file exist in the specified path or not.
Syntax:
file_exists ( string $filename )
Returns TRUE
if the file or directory specified by filename exists; FALSE
otherwise.
$filename = BASE_DIR."images/a/test.jpg";
if (file_exists($filename)){
echo "File exist.";
}else{
echo "File does not exist.";
}
Another alternative method you can use getimagesize(), it will return 0(zero) if file/directory is not available in the specified path.
if (@getimagesize($filename)) {...}
You can check for a module's installation path by:
perldoc -l XML::Simple
The problem with your one-liner is that, it is not recursively traversing directories/sub-directories. Hence, you get only pragmatic module names as output.
Like this.
import java.util.Date;
import java.util.GregorianCalendar;
/**
* DateDiff -- compute the difference between two dates.
*/
public class DateDiff {
public static void main(String[] av) {
/** The date at the end of the last century */
Date d1 = new GregorianCalendar(2000, 11, 31, 23, 59).getTime();
/** Today's date */
Date today = new Date();
// Get msec from each, and subtract.
long diff = today.getTime() - d1.getTime();
System.out.println("The 21st century (up to " + today + ") is "
+ (diff / (1000 * 60 * 60 * 24)) + " days old.");
}
}
Here is an article on Java date arithmetic.
From RFC 2616:
HTTP communication usually takes place over TCP/IP connections. The default port is TCP 80, but other ports can be used. This does not preclude HTTP from being implemented on top of any other protocol on the Internet, or on other networks. HTTP only presumes a reliable transport; any protocol that provides such guarantees can be used; the mapping of the HTTP/1.1 request and response structures onto the transport data units of the protocol in question is outside the scope of this specification.
So although it doesn't explicitly say so, UDP is not used because it is not a "reliable transport".
EDIT - more recently, the QUIC protocol (which is more strictly a pseudo-transport or a session layer protocol) does use UDP for carrying HTTP/2.0 traffic and much of Google's traffic already uses this protocol. It's currently progressing towards standardisation as HTTP/3.
The shortest way is by adding the ObsoleteAttribute
as an attribute to the method. Make sure to include an appropriate explanation:
[Obsolete("Method1 is deprecated, please use Method2 instead.")]
public void Method1()
{ … }
You can also cause the compilation to fail, treating the usage of the method as an error instead of warning, if the method is called from somewhere in code like this:
[Obsolete("Method1 is deprecated, please use Method2 instead.", true)]
Replacing:
$_SERVER["REMOTE_ADDR"];
With:
$_SERVER["HTTP_X_REAL_IP"];
Worked for me.
This will work perfectly
<form method='post' enctype="multipart/form-data">
<input type='file' name='uploaded_file' id='uploaded_file' multiple='multiple' />
<input type='submit' name='upload'/>
</form>
<?php
if(isset($_POST['upload']))
{
if (isset($_FILES['uploaded_file']) && $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK)
{
if (array_key_exists('uploaded_file', $_FILES))
{
$mail->Subject = "My Subject";
$mail->Body = 'This is the body';
$uploadfile = tempnam(sys_get_temp_dir(), sha1($_FILES['uploaded_file']['name']));
if (move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $uploadfile))
$mail->addAttachment($uploadfile,$_FILES['uploaded_file']['name']);
$mail->send();
echo 'Message has been sent';
}
else
echo "The file is not uploaded. please try again.";
}
else
echo "The file is not uploaded. please try again";
}
?>
For those like I who just followed the code by skuntsel and received a cryptic stack trace, allow me to save you some time.
It seems c:if
cannot by itself be followed by c:otherwise
.
The correct solution is as follows:
<c:choose>
<c:when test="#{some.test}">
<p>some.test is true</p>
</c:when>
<c:otherwise>
<p>some.test is not true</p>
</c:otherwise>
</c:choose>
You can add additional c:when
tests in as necessary.
IllegalStateException is encountered if you commit any fragment transaction after the activity has lost its state- Activity is not in foreground. This is commonly encountered when you try to commit any fragment in AsyncTask or after a network request.
To avoid this crash you just need to delay any fragment transaction untill the state of activity is restored. Following is how it is done
Declare two private boolean variables
public class MainActivity extends AppCompatActivity {
//Boolean variable to mark if the transaction is safe
private boolean isTransactionSafe;
//Boolean variable to mark if there is any transaction pending
private boolean isTransactionPending;
Now in onPostResume() and onPause we set and unset our boolean variable isTransactionSafe. Idea is to mark trasnsaction safe only when the activity is in foreground so there is no chance of stateloss.
/*
onPostResume is called only when the activity's state is completely restored. In this we will
set our boolean variable to true. Indicating that transaction is safe now
*/
public void onPostResume(){
super.onPostResume();
isTransactionSafe=true;
}
/*
onPause is called just before the activity moves to background and also before onSaveInstanceState. In this
we will mark the transaction as unsafe
*/
public void onPause(){
super.onPause();
isTransactionSafe=false;
}
private void commitFragment(){
if(isTransactionSafe) {
MyFragment myFragment = new MyFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.frame, myFragment);
fragmentTransaction.commit();
}
}
What we have done so far will save from IllegalStateException but our transactions will be lost if they are done after the activity moves to background, kind of like commitAllowStateloss(). To help with that we have isTransactionPending boolean variable
public void onPostResume(){
super.onPostResume();
isTransactionSafe=true;
/* Here after the activity is restored we check if there is any transaction pending from
the last restoration
*/
if (isTransactionPending) {
commitFragment();
}
}
private void commitFragment(){
if(isTransactionSafe) {
MyFragment myFragment = new MyFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.frame, myFragment);
fragmentTransaction.commit();
isTransactionPending=false;
}else {
/*
If any transaction is not done because the activity is in background. We set the
isTransactionPending variable to true so that we can pick this up when we come back to
foreground
*/
isTransactionPending=true;
}
}
This article explains quite in detail of why this exception is encountered and compares various methods to resolve it . Highly recommended
From your comments, it seems like you're looking for "best practices" for the use of the Boolean
wrapper class. But there really aren't any best practices, because it's a bad idea to use this class to begin with. The only reason to use the object wrapper is in cases where you absolutely must (such as when using Generics, i.e., storing a boolean
in a HashMap<String, Boolean>
or the like). Using the object wrapper has no upsides and a lot of downsides, most notably that it opens you up to NullPointerException
s.
Does it matter if '!' is used instead of .equals() for Boolean?
Both techniques will be susceptible to a NullPointerException
, so it doesn't matter in that regard. In the first scenario, the Boolean
will be unboxed into its respective boolean
value and compared as normal. In the second scenario, you are invoking a method from the Boolean
class, which is the following:
public boolean equals(Object obj) {
if (obj instanceof Boolean) {
return value == ((Boolean)obj).booleanValue();
}
return false;
}
Either way, the results are the same.
Would it matter if .equals(false) was used to check for the value of the Boolean checker?
Per above, no.
Secondary question: Should Boolean be dealt differently than boolean?
If you absolutely must use the Boolean
class, always check for null
before performing any comparisons. e.g.,
Map<String, Boolean> map = new HashMap<String, Boolean>();
//...stuff to populate the Map
Boolean value = map.get("someKey");
if(value != null && value) {
//do stuff
}
This will work because Java short-circuits conditional evaluations. You can also use the ternary operator.
boolean easyToUseValue = value != null ? value : false;
But seriously... just use the primitive type, unless you're forced not to.
Just drop the option v
.
-v
is for verbose. If you don't use it then it won't display:
tar -zxf tmp.tar.gz -C ~/tmp1
pip
is a package manager.
conda
is both a package manager and an environment manager.

Edit 2015
Someone has made a project on NPM with my solution: https://github.com/lovasoa/react-contenteditable
Edit 06/2016: I've just encoutered a new problem that occurs when the browser tries to "reformat" the html you just gave him, leading to component always re-rendering. See
Edit 07/2016: here's my production contentEditable implementation. It has some additional options over react-contenteditable
that you might want, including:
FakeRainBrigand's solution has worked quite fine for me for some time until I got new problems. ContentEditables are a pain, and are not really easy to deal with React...
This JSFiddle demonstrates the problem.
As you can see, when you type some characters and click on Clear
, the content is not cleared. This is because we try to reset the contenteditable to the last known virtual dom value.
So it seems that:
shouldComponentUpdate
to prevent caret position jumpsshouldComponentUpdate
this way.So you need an extra line so that whenever shouldComponentUpdate
returns yes, you are sure the DOM content is actually updated.
So the version here adds a componentDidUpdate
and becomes:
var ContentEditable = React.createClass({
render: function(){
return <div id="contenteditable"
onInput={this.emitChange}
onBlur={this.emitChange}
contentEditable
dangerouslySetInnerHTML={{__html: this.props.html}}></div>;
},
shouldComponentUpdate: function(nextProps){
return nextProps.html !== this.getDOMNode().innerHTML;
},
componentDidUpdate: function() {
if ( this.props.html !== this.getDOMNode().innerHTML ) {
this.getDOMNode().innerHTML = this.props.html;
}
},
emitChange: function(){
var html = this.getDOMNode().innerHTML;
if (this.props.onChange && html !== this.lastHtml) {
this.props.onChange({
target: {
value: html
}
});
}
this.lastHtml = html;
}
});
The Virtual dom stays outdated, and it may not be the most efficient code, but at least it does work :) My bug is resolved
Details:
1) If you put shouldComponentUpdate to avoid caret jumps, then the contenteditable never rerenders (at least on keystrokes)
2) If the component never rerenders on key stroke, then React keeps an outdated virtual dom for this contenteditable.
3) If React keeps an outdated version of the contenteditable in its virtual dom tree, then if you try to reset the contenteditable to the value outdated in the virtual dom, then during the virtual dom diff, React will compute that there are no changes to apply to the DOM!
This happens mostly when:
I'm using XAMPP, in which there are several php.ini files.
You can find the line in the php.ini files:
;extension=php_curl.dll
Please remove ;
at the beginning of this line. And you may need to restart apache server.
The code that worked for me is:
ThisWorkbook.Sheets("sheetName").Activate
I came across this question, but in order to make it work for my case (using dragover on a DOM-element (not being canvas in my case)), I found that you only have have to use offsetX
and offsetY
on the dragover-mouse event.
onDragOver(event){
var x = event.offsetX;
var y = event.offsetY;
}
The ternary operator (?:
) is not designed for control flow, it's only designed for conditional assignment. If you need to control the flow of your program, use a control structure, such as if
/else
.
USE dbName;
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE (TABLE_SCHEMA = 'dbName' OR TABLE_SCHEMA = 'schemaName')
ORDER BY TABLE_NAME
If you are working with multiple schemata on an MS SQL server, then SELECT-ing TABLE_NAME without also simultaneously selecting TABLE_SCHEMA might be of limited benefit, so I have assumed we are interested in the tables belonging to a known schema when using MS SQL Server.
I have tested the query above with SQL Server Management Studio using an SQL Server database of mine and with MySQL Workbench using a MySQL database, and in both cases it gives the table names.
The query bodges Michael Baylon's two different queries into one that can then run on either database type. The first part of the WHERE clause works on MySQL databases and the second part (after the OR) works on MS SQL Server databases. It is ugly and logically a little incorrect as it supposes that there is no undesired schema with the same name as the database. This might help someone who is looking for one single query that can run on either database server.
One way would be:
while read NAME
do
echo "$NAME"
done < names.txt
EDIT:
Note that the loop gets executed in a sub-shell, so any modified variables will be local, except if you declare them with declare
outside the loop.
Dennis Williamson is right. Sorry, must have used piped constructs too often and got confused.
There is a modern API dedicated for this purpose - Broadcast Channel
It is as easy as:
var bc = new BroadcastChannel('test_channel');
bc.postMessage('This is a test message.'); /* send */
bc.onmessage = function (ev) { console.log(ev); } /* receive */
There is no need for the message to be just a DOMString, any kind of object can be sent.
Probably, apart from API cleanness, it is the main benefit of this API - no object stringification.
Currently supported only in Chrome and Firefox, but you can find a polyfill that uses localStorage.
Assuming that you really mean "print" on a real printing terminal:
>>> text = 'foo bar\r\noof\trab\r\n'
>>> ''.join(s if i & 1 else (s + '\b' * len(s)) * 2 + s
... for i, s in enumerate(re.split(r'(\s+)', text)))
'foo\x08\x08\x08foo\x08\x08\x08foo bar\x08\x08\x08bar\x08\x08\x08bar\r\noof\x08\
x08\x08oof\x08\x08\x08oof\trab\x08\x08\x08rab\x08\x08\x08rab\r\n'
Just send that to your stdout
.
Running git pull
performs the following tasks, in order:
git fetch
git merge
The merge step combines branches that have been setup to be merged in your config. You want to undo the merge step, but probably not the fetch (doesn't make a lot of sense and shouldn't be necessary).
To undo the merge, use git reset --hard
to reset the local repository to a previous state; use git-reflog to find the SHA-1 of the previous state and then reset to it.
Warning
The commands listed in this section remove all uncommitted changes, potentially leading to a loss of work:
git reset --hard
Alternatively, reset to a particular point in time, such as:
git reset --hard master@{"10 minutes ago"}
At first check the file address, it must be beside your .java
file or in any address that you define in classpath
environment variable. When you check this then try below.
you must use a file name by it's extension in File object constructor, as an example:
File myFile = new File("test.txt");
but there is a better way to use it inside Scanner object by pass the filename absolute address, as an example:
Scanner sc = new Scanner(Paths.get("test.txt"));
in this way you must import java.nio.file.Paths
as well.
I am aware there are already several answers, but I added this, as this adds substantial information about the decimal places and hence the asked maximum length.
The length of latitude and langitude depend on precision. The absolute maximum length for each is:
For both holds: a maximum of 8 decial places is possible (though not commonly used).
Explanation for the dependency on precision:

It seems like they added a new Class named android.widget.Toolbar
that extends ViewGroup
. Also they added a new method setActionBar(Toolbar)
in Activity
. I haven't tested it yet, but it looks like you can wrap all kinds of TabWidgets
, Spinners
or custom views into a Toolbar
and use it as your Actionbar.
As stated in the documentation, built-in hash() function is not designed for storing resulting hashes somewhere externally. It is used to provide object's hash value, to store them in dictionaries and so on. It's also implementation-specific (GAE uses a modified version of Python). Check out:
>>> class Foo:
... pass
...
>>> a = Foo()
>>> b = Foo()
>>> hash(a), hash(b)
(-1210747828, -1210747892)
As you can see, they are different, as hash() uses object's __hash__
method instead of 'normal' hashing algorithms, such as SHA.
Given the above, the rational choice is to use the hashlib module.
In case anybody wonders how how to get rid of the rest of the white margin after applying plt.tight_layout()
or fig.tight_layout()
: With the parameter pad
(which is 1.08
by default), you're able to make it even tighter:
"Padding between the figure edge and the edges of subplots, as a fraction of the font size."
So for example
plt.tight_layout(pad=0.05)
will reduce it to a very small margin. Putting 0
doesn't work for me, as it makes the box of the subplot be cut off a little, too.
I tried with this method and it significantly reduced my database insert execution time.
List<string> toinsert = new List<string>();
StringBuilder insertCmd = new StringBuilder("INSERT INTO tabblename (col1, col2, col3) VALUES ");
foreach (var row in rows)
{
// the point here is to keep values quoted and avoid SQL injection
var first = row.First.Replace("'", "''")
var second = row.Second.Replace("'", "''")
var third = row.Third.Replace("'", "''")
toinsert.Add(string.Format("( '{0}', '{1}', '{2}' )", first, second, third));
}
if (toinsert.Count != 0)
{
insertCmd.Append(string.Join(",", toinsert));
insertCmd.Append(";");
}
using (MySqlCommand myCmd = new MySqlCommand(insertCmd.ToString(), SQLconnectionObject))
{
myCmd.CommandType = CommandType.Text;
myCmd.ExecuteNonQuery();
}
*Create SQL connection object and replace it where I have written SQLconnectionObject.
TLDR for people comming from c++
It's just overloaded operator of ( )
parentheses
So in scala:
class X {
def apply(param1: Int, param2: Int, param3: Int) : Int = {
// Do something
}
}
Is same as this in c++:
class X {
int operator()(int param1, int param2, int param3) {
// do something
}
};
None of the existing answers here has provided a complete example of how to do this from within a script (not a one-liner). Here is what I did:
rename($file, $file.'.bak');
open(IN, '<'.$file.'.bak') or die $!;
open(OUT, '>'.$file) or die $!;
while(<IN>)
{
$_ =~ s/blue/red/g;
print OUT $_;
}
close(IN);
close(OUT);
I wanted to change default java version form 1.6* to 1.7*. I tried the following steps and it worked for me:
ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin/java java
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
I didn't want to open another threat so ill post my problem here

Although already over a year old, I stumbled across this question a couple of times on other Google search and I believe I can improve on the previous answer for the benefit of others.
Short answer is you cannot combine both action in one line, but you can create a chain that does what you want and then call it in a one liner.
Let's create a chain to log and accept:
iptables -N LOG_ACCEPT
And let's populate its rules:
iptables -A LOG_ACCEPT -j LOG --log-prefix "INPUT:ACCEPT:" --log-level 6
iptables -A LOG_ACCEPT -j ACCEPT
Now let's create a chain to log and drop:
iptables -N LOG_DROP
And let's populate its rules:
iptables -A LOG_DROP -j LOG --log-prefix "INPUT:DROP: " --log-level 6
iptables -A LOG_DROP -j DROP
Now you can do all actions in one go by jumping (-j) to you custom chains instead of the default LOG / ACCEPT / REJECT / DROP:
iptables -A <your_chain_here> <your_conditions_here> -j LOG_ACCEPT
iptables -A <your_chain_here> <your_conditions_here> -j LOG_DROP
Use the mask-image
property, but it's a bit of a hack. It's demonstrated in the Safari blog here.
It's also described in-depth here.
Basically you'd create a CSS box, with say a background-image: gradient(foo);
and then apply an image mask to it based on those PNG images.
It would save you development time making individual images in Photoshop, but I don't think it would save much bandwidth unless you'll be displaying the images in a wide variety of colours. Personally I wouldn't use it because you need to adjust your markup to use the technique effectively, but I'm a member of the "purity is imperitive" school-of-thought.
It's not difficult and actually documented:
import youtube_dl
ydl = youtube_dl.YoutubeDL({'outtmpl': '%(id)s.%(ext)s'})
with ydl:
result = ydl.extract_info(
'http://www.youtube.com/watch?v=BaW_jenozKc',
download=False # We just want to extract the info
)
if 'entries' in result:
# Can be a playlist or a list of videos
video = result['entries'][0]
else:
# Just a video
video = result
print(video)
video_url = video['url']
print(video_url)

round(x[, n]): values are rounded to the closest multiple of 10 to the power minus n. So if n is negative...
def round5(x):
return int(round(x*2, -1)) / 2
Since 10 = 5 * 2, you can use integer division and multiplication with 2, rather than float division and multiplication with 5.0. Not that that matters much, unless you like bit shifting
def round5(x):
return int(round(x << 1, -1)) >> 1
The user that is configured to run this scheduled task must have "Log on as a batch job" rights on the computer that hosts the exe you are launching. This can be configured on the local security policy of the computer that hosts the exe. You can change the policy (on the server hosting the exe) under
Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log On As Batch Job
Add your user to this list (you could also make the user account a local admin on the machine hosting the exe).
Finally, you could also simply copy your exe from the network location to your local computer and run it from there instead.
Note also that a domain policy could be restricting "Log on as a batch job" rights at your organization.
Also, starting with .NET Core 3.0 (and .NET Standard 2.1) (C# 8) you can use Index
type to keep array's indexes from end:
var lastElementIndexInAnyArraySize = ^1;
var lastElement = array[lastElementIndexInAnyArraySize];
You can use this index to get last array value in any lenght of array. For example:
var firstArray = new[] {0, 1, 1, 2, 2};
var secondArray = new[] {3, 3, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5};
var index = ^1;
var firstArrayLastValue = firstArray[index]; // 2
var secondArrayLastValue = secondArray[index]; // 5
For more information check documentation
For Scala >= 2.12, use Source.fromResource
:
scala.io.Source.fromResource("located_in_resouces.any")
My search led me here so might as well add my two cents worth of idea. If you are using Monkey friendly Twitter Bootstrap modal then you can do something like this:
var dialog = new BootstrapDialog({
id: 'myDialog',
title: 'Title',
closable: false,
// whatever you like configuration here...
});
dialog.realize();
if (isContentAYoutubeVideo()) {
dialog.getModalDialog().css('width', '80%'); // set the width to whatever you like
}
dialog.open();
Hope this helps.
This exact question is answered on mySql workbench-faq:
Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.
That means hover over an acronym in the mySql Workbench table editor.
You can use At
from pydash:
from pydash import at
dict = {'a': 1, 'b': 2, 'c': 3}
list = at(dict, 'a', 'b')
list == [1, 2]
The A div can actually be made without :before
or :after
selector but using linear gradient as your first try. The only difference is that you must specify 4 positions. Dark grey from 0 to 50% and ligth grey from 50% to 100% like this:
background: linear-gradient(to right, #9c9e9f 0%,#9c9e9f 50%,#f6f6f6 50%,#f6f6f6 100%);
As you know, B div is made from a linear gradient having 2 positions like this:
background: linear-gradient(to right, #9c9e9f 0%,#f6f6f6 100%);
For the C div, i use the same kind of gradient as div A ike this:
background: linear-gradient(to right, #9c9e9f 0%,#9c9e9f 50%,#33ccff 50%,#33ccff 100%);
But this time i used the :after
selector with a white background like if the second part of your div was smaller. * Please note that I added a better alternative below.

There is also an alternative for the C div without using a white background to hide the a part of the second section.
Instead, we make the second part transparent and we use the :after
selector to act as a colored background with the desired position and size.

You can use MemberwiseClone
obj myobj2 = (obj)myobj.MemberwiseClone();
The copy is a shallow copy which means the reference properties in the clone are pointing to the same values as the original object but that shouldn't be an issue in your case as the properties in obj
are of value types.
If you own the source code, you can also implement ICloneable
Running this approach will in fact toggle the checkbox; .isSelected()
in Java/Selenium 2 apparently always returns false
(at least with the Java, Selenium, and Firefox versions I tested it with).
The selection of the proper checkbox isn't where the problem lies -- rather, it is in distinguishing correctly the initial state to needlessly avoid reclicking an already-checked box.
The second approach is clearly wrong if you want to cast. It instantiate a new ArrayList.
However the first approach should work just fine, if and only if getAllTasks return an ArrayList.
It is really needed for you to have an ArrayList ? isn't the List interface enough ? What you are doing can leads to Runtime Exception if the type isn't correct.
If getAllTasks() return an ArrayList you should change the return type in the class definition and then you won't need a cast and if it's returning something else, you can't cast to ArrayList.
Here's some more detailed information on what Client, Resource, and Session are all about.
Client:
Here's an example of client-level access to an S3 bucket's objects (at most 1000**):
import boto3
client = boto3.client('s3')
response = client.list_objects_v2(Bucket='mybucket')
for content in response['Contents']:
obj_dict = client.get_object(Bucket='mybucket', Key=content['Key'])
print(content['Key'], obj_dict['LastModified'])
** you would have to use a paginator, or implement your own loop, calling list_objects() repeatedly with a continuation marker if there were more than 1000.
Resource:
Here's the equivalent example using resource-level access to an S3 bucket's objects (all):
import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
for obj in bucket.objects.all():
print(obj.key, obj.last_modified)
Note that in this case you do not have to make a second API call to get the objects; they're available to you as a collection on the bucket. These collections of subresources are lazily-loaded.
You can see that the Resource
version of the code is much simpler, more compact, and has more capability (it does pagination for you). The Client
version of the code would actually be more complicated than shown above if you wanted to include pagination.

Yahoo's api provides a CSV dump:
Example: http://finance.yahoo.com/d/quotes.csv?s=msft&f=price
I'm not sure if it is documented or not, but this code sample should showcase all of the features (namely the stat types [parameter f in the query string]. I'm sure you can find documentation (official or not) if you search for it.

Edit
I found some unofficial documentation:
UPDATE : The accepted answer provides the solution, but .on() is the method that should be use from now on.
"As of jQuery 3.0, .bind() has been deprecated. It was superseded by the .on() method for attaching event handlers to a document since jQuery 1.7, so its use was already discouraged."
You can try with this below command:
python -m pip install --trusted-host https://pypi.python.org deepdiff
it will work.
You just need to add [FromUri]
before parameter, looks like:
GetCategories([FromUri] int[] categoryIds)
And send request:
/Categories?categoryids=1&categoryids=2&categoryids=3
I need to somehow query Google and ask: Is this access token valid for [email protected]?
No. All you need is request standard login with Federated Login for Google Account Users from your API domain. And only after that you could compare "persistent user ID" with one you have from 'public interface'.
The value of realm is used on the Google Federated Login page to identify the requesting site to the user. It is also used to determine the value of the persistent user ID returned by Google.
So you need be from same domain as 'public interface'.
And do not forget that user needs to be sure that your API could be trusted ;) So Google will ask user if it allows you to check for his identity.
Please look up the difference between &
and &&
in Java (the same applies to |
and ||
).
&
and |
are just logical operators, while &&
and ||
are conditional logical operators, which in your example means that
if(bool1 && bool2 && bool3) {
will skip bool2
and bool3
if bool1
is false, and
if(bool1 & bool2 & bool3) {
will evaluate all conditions regardless of their values.
For example, given:
boolean foo() {
System.out.println("foo");
return true;
}
if(foo() | foo())
will print foo
twice, and if(foo() || foo())
- just once.
or programatically
TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
Use jQuery:
$.ajax({ url: 'your-url', success: function(data) { alert(data); } });
This data is your HTML.
Without jQuery (just JavaScript):
function makeHttpObject() {
try {return new XMLHttpRequest();}
catch (error) {}
try {return new ActiveXObject("Msxml2.XMLHTTP");}
catch (error) {}
try {return new ActiveXObject("Microsoft.XMLHTTP");}
catch (error) {}
throw new Error("Could not create HTTP request object.");
}
var request = makeHttpObject();
request.open("GET", "your_url", true);
request.send(null);
request.onreadystatechange = function() {
if (request.readyState == 4)
alert(request.responseText);
};
Python 3.0 doesn't have sys.maxint any more since Python 3's ints are of arbitrary length. Instead of sys.maxint it has sys.maxsize; the maximum size of a positive sized size_t aka Py_ssize_t.
DO NOT Use GUID For Key
ScriptManager.RegisterClientScriptBlock(this.Page, typeof(UpdatePanel)
Guid.NewGuid().ToString(), myScript, true);
and if you want to do that , call Something Like this function
public static string GetGuidClear(string x)
{
return x.Replace("-", "").Replace("0", "").Replace("1", "")
.Replace("2", "").Replace("3", "").Replace("4", "")
.Replace("5", "").Replace("6", "").Replace("7", "")
.Replace("8", "").Replace("9", "");
}
As delnan pointed out, the match
keyword in Scala has nothing to do with regexes. To find out whether a string matches a regex, you can use the String.matches
method. To find out whether a string starts with an a, b or c in lower or upper case, the regex would look like this:
word.matches("[a-cA-C].*")
You can read this regex as "one of the characters a, b, c, A, B or C followed by anything" (.
means "any character" and *
means "zero or more times", so ".*" is any string).
Create Bean for Rest Template to auto wiring the Rest Template object.
@SpringBootApplication
public class ChatAppApplication {
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ChatAppApplication.class, args);
}
}
Consume the GET/POST API by using RestTemplate - exchange() method. Below is for the post api which is defined in the controller.
@RequestMapping(value = "/postdata",method = RequestMethod.POST)
public String PostData(){
return "{\n" +
" \"value\":\"4\",\n" +
" \"name\":\"David\"\n" +
"}";
}
@RequestMapping(value = "/post")
public String getPostResponse(){
HttpHeaders headers=new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity=new HttpEntity<String>(headers);
return restTemplate.exchange("http://localhost:8080/postdata",HttpMethod.POST,entity,String.class).getBody();
}
Refer this tutorial[1]

You don't have permission to the Python folder.
sudo chown -R $USER /usr/local/lib/python2.7
This was close to working for me. Also had to add:
"changeOrigin": true,
"pathRewrite": {"^/proxy" : ""}
Full proxy.conf.json
shown below:
{
"/proxy/*": {
"target": "https://url.com",
"secure": false,
"changeOrigin": true,
"logLevel": "debug",
"pathRewrite": {
"^/proxy": ""

Under SuSE 13.1, this works fine to move the mysql data directory elsewhere, e.g. to /home/example_user/ , and to give it a more informative name:
In /var/lib/ :
# mv -T mysql /home/example_user/mysql_datadir
# ln -s /home/example_user/mysql_datadir ./mysql
I restarted mysql:
# systemctl restart mysql.service
but suspect that even that wasn't necessary.
This is the function which I am using, tested and worked well. please bear in mind that 'input' should not be null and 'input.position' should reset to '0' before reading otherwise it will break the read loop and nothing will read to convert to array.
public static byte[] StreamToByteArray(Stream input)
{
if (input == null)
return null;
byte[] buffer = new byte[16 * 1024];
input.Position = 0;
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
byte[] temp = ms.ToArray();
return temp;
}
}
It turns out that I needed to use gulp-rename
and also output the concatenated file first before 'uglification'. Here's the code:
var gulp = require('gulp'),
gp_concat = require('gulp-concat'),
gp_rename = require('gulp-rename'),
gp_uglify = require('gulp-uglify');
gulp.task('js-fef', function(){
return gulp.src(['file1.js', 'file2.js', 'file3.js'])
.pipe(gp_concat('concat.js'))
.pipe(gulp.dest('dist'))
.pipe(gp_rename('uglify.js'))
.pipe(gp_uglify())
.pipe(gulp.dest('dist'));
});
gulp.task('default', ['js-fef'], function(){});
Coming from grunt
it was a little confusing at first but it makes sense now. I hope it helps the gulp
noobs.
And, if you need sourcemaps, here's the updated code:
var gulp = require('gulp'),
gp_concat = require('gulp-concat'),
gp_rename = require('gulp-rename'),
gp_uglify = require('gulp-uglify'),
gp_sourcemaps = require('gulp-sourcemaps');
gulp.task('js-fef', function(){
return gulp.src(['file1.js', 'file2.js', 'file3.js'])
.pipe(gp_sourcemaps.init())
.pipe(gp_concat('concat.js'))
.pipe(gulp.dest('dist'))
.pipe(gp_rename('uglify.js'))
.pipe(gp_uglify())
.pipe(gp_sourcemaps.write('./'))
.pipe(gulp.dest('dist'));
});
gulp.task('default', ['js-fef'], function(){});
See gulp-sourcemaps for more on options and configuration.
You can try the trim() method.
String newString = oldString.trim();
Take a look at javadocs
As already pointed out by @snishalaka, you can increase the number of inotify watchers.
However, I think the default number is high enough and is only reached when processes are not cleaned up properly. Hence, I simply restarted my computer as proposed on a related github issue and the error message was gone.
I was able to successfully pass through the data attribute in the ajax method. Here is my code
$.ajax({
url: "/api/Gigs/Cancel",
type: "DELETE",
data: {
"GigId": link.attr('data-gig-id')
}
})
The link.attr method simply returned the value of 'data-gig-id' .
Create a folder ${USER_HOME}/.mvn
and put a file called maven.config
in it.
The content should be:
-Dmaven.wagon.http.ssl.insecure=true
-Dmaven.wagon.http.ssl.allowall=true
-Dmaven.wagon.http.ssl.ignore.validity.dates=true
Hope this helps.
One possible solution is do the concatenation manually, here is some useful code:
import json
def append_to_json(_dict,path):
with open(path, 'ab+') as f:
f.seek(0,2) #Go to the end of file
if f.tell() == 0 : #Check if file is empty
f.write(json.dumps([_dict]).encode()) #If empty, write an array
else :
f.seek(-1,2)
f.truncate() #Remove the last character, open the array
f.write(' , '.encode()) #Write the separator
f.write(json.dumps(_dict).encode()) #Dump the dictionary
f.write(']'.encode()) #Close the array
You should be careful when editing the file outside the script not add any spacing at the end.
No, it is not "required", but it might as well be as it can cause major issues down the line if you don't. Not defining a variable with var put that variable inside the scope of the part of the code it's in. If you don't then it isn't contained in that scope and can overwrite previously defined variables with the same name that are outside the scope of the function you are in.
Other way with Git Bash:
stopProcessByPortNumber() {
port=":${1}"
portStrLine="$(netstat -ano | findstr LISTENING | findstr $port)"
processId="$(grep -oP '(\d+)(?!.*\d)' <<< $portStrLine)"
echo $processId
taskkill -PID $processId -F
}
I tried all the non-plugin approaches here, but all caused blank pages to print after the content, or had other problems. Here's my solution:
Html:
<body>
<div id="page-content">
<div id="printme">Content To Print</div>
<div>Don't print this.</div>
</div>
<div id="hidden-print-div"></div>
</body>
Jquery:
$(document).ready(function () {
$("#hidden-print-div").html($("#printme").html());
});
Css:
#hidden-print-div {
display: none;
}
@media print {
#hidden-print-div {
display: block;
}
#page-content {
display: none;
}
}
Here is my simple and working function to generate a Bitmap! I Use ZXing1.3.jar only! I've also set Correction Level to High!
PS: x and y are reversed, it's normal, because bitMatrix reverse x and y. This code works perfectly with a square image.
public static Bitmap generateQrCode(String myCodeText) throws WriterException {
Hashtable<EncodeHintType, ErrorCorrectionLevel> hintMap = new Hashtable<EncodeHintType, ErrorCorrectionLevel>();
hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.H); // H = 30% damage
QRCodeWriter qrCodeWriter = new QRCodeWriter();
int size = 256;
ByteMatrix bitMatrix = qrCodeWriter.encode(myCodeText,BarcodeFormat.QR_CODE, size, size, hintMap);
int width = bitMatrix.width();
Bitmap bmp = Bitmap.createBitmap(width, width, Bitmap.Config.RGB_565);
for (int x = 0; x < width; x++) {
for (int y = 0; y < width; y++) {
bmp.setPixel(y, x, bitMatrix.get(x, y)==0 ? Color.BLACK : Color.WHITE);
}
}
return bmp;
}
EDIT
It's faster to use bitmap.setPixels(...) with a pixel int array instead of bitmap.setPixel one by one:
BitMatrix bitMatrix = writer.encode(inputValue, BarcodeFormat.QR_CODE, size, size);
int width = bitMatrix.getWidth();
int height = bitMatrix.getHeight();
int[] pixels = new int[width * height];
for (int y = 0; y < height; y++) {
int offset = y * width;
for (int x = 0; x < width; x++) {
pixels[offset + x] = bitMatrix.get(x, y) ? BLACK : WHITE;
}
}
bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
bitmap.setPixels(pixels, 0, width, 0, 0, width, height);
As a bonus for setting up a Title Case shortcut key Ctrl+kt (while holding Ctrl, press k and t), go to Preferences
--> Keybindings-User
If you have a blank file open and close with the square brackets:
[ { "keys": ["ctrl+k", "ctrl+t"], "command": "title_case" } ]
Otherwise if you already have stuff in there, just make sure if it comes after another command to prepend a comma "," and add:
{ "keys": ["ctrl+k", "ctrl+t"], "command": "title_case" }
I had the same problem with Pool()
in Python 3.6.3.
Error received: TypeError: can't pickle _thread.RLock objects
Let's say we want to add some number num_to_add
to each element of some list num_list
in parallel. The code is schematically like this:
class DataGenerator:
def __init__(self, num_list, num_to_add)
self.num_list = num_list # e.g. [4,2,5,7]
self.num_to_add = num_to_add # e.g. 1
self.run()
def run(self):
new_num_list = Manager().list()
pool = Pool(processes=50)
results = [pool.apply_async(run_parallel, (num, new_num_list))
for num in num_list]
roots = [r.get() for r in results]
pool.close()
pool.terminate()
pool.join()
def run_parallel(self, num, shared_new_num_list):
new_num = num + self.num_to_add # uses class parameter
shared_new_num_list.append(new_num)
The problem here is that self
in function run_parallel()
can't be pickled as it is a class instance. Moving this parallelized function run_parallel()
out of the class helped. But it's not the best solution as this function probably needs to use class parameters like self.num_to_add
and then you have to pass it as an argument.
Solution:
def run_parallel(num, shared_new_num_list, to_add): # to_add is passed as an argument
new_num = num + to_add
shared_new_num_list.append(new_num)
class DataGenerator:
def __init__(self, num_list, num_to_add)
self.num_list = num_list # e.g. [4,2,5,7]
self.num_to_add = num_to_add # e.g. 1
self.run()
def run(self):
new_num_list = Manager().list()
pool = Pool(processes=50)
results = [pool.apply_async(run_parallel, (num, new_num_list, self.num_to_add)) # num_to_add is passed as an argument
for num in num_list]
roots = [r.get() for r in results]
pool.close()
pool.terminate()
pool.join()
Other suggestions above didn't help me.
If you are working with Flutter then this command would definitely work for you.
flutter doctor --android-licenses
You're very close. What you need to remember is when you're calling a method from another class you need to tell the compiler where to find that method.
So, instead of simply calling addWord("someWord")
, you will need to initialise an instance of the WordList class (e.g. WordList list = new WordList();
), and then call the method using that (i.e. list.addWord("someWord");
.
However, your code at the moment will still throw an error there, because that would be trying to call a non-static method from a static one. So, you could either make addWord()
static, or change the methods in the Words class so that they're not static.
My bad with the above paragraph - however you might want to reconsider ProcessInput()
being a static method - does it really need to be?
Label's aren't form elements. They don't have a value
. They have innerHTML
and textContent
.
Thus,
$('#telefon').html()
// or
$('#telefon').text()
or
var telefon = document.getElementById('telefon');
telefon.innerHTML;
If you are starting with your form element, check out the labels
list of it. That is,
var el = $('#myformelement');
var label = $( el.prop('labels') );
// label.html();
// el.val();
// blah blah blah you get the idea
I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
You can try the following library: Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.
Fiddler is the winner every time when comparing to Charles.
The "customize rules" feature of fiddler is unparalleled in any http debugger. The ability to write code to manipulate http requests and responses on-the-fly is invaluable to me and the work I do in web development.
There are so many features to fiddler that charles just does not have, and likely won't ever have. Fiddler is light-years ahead.
Swift 3 UIImage extension:
func fixOrientation() -> UIImage {
// No-op if the orientation is already correct
if ( self.imageOrientation == .up ) {
return self;
}
// We need to calculate the proper transformation to make the image upright.
// We do it in 2 steps: Rotate if Left/Right/Down, and then flip if Mirrored.
var transform: CGAffineTransform = .identity
if ( self.imageOrientation == .down || self.imageOrientation == .downMirrored ) {
transform = transform.translatedBy(x: self.size.width, y: self.size.height)
transform = transform.rotated(by: .pi)
}
if ( self.imageOrientation == .left || self.imageOrientation == .leftMirrored ) {
transform = transform.translatedBy(x: self.size.width, y: 0)
transform = transform.rotated(by: .pi/2)
}
if ( self.imageOrientation == .right || self.imageOrientation == .rightMirrored ) {
transform = transform.translatedBy(x: 0, y: self.size.height);
transform = transform.rotated(by: -.pi/2);
}
if ( self.imageOrientation == .upMirrored || self.imageOrientation == .downMirrored ) {
transform = transform.translatedBy(x: self.size.width, y: 0)
transform = transform.scaledBy(x: -1, y: 1)
}
if ( self.imageOrientation == .leftMirrored || self.imageOrientation == .rightMirrored ) {
transform = transform.translatedBy(x: self.size.height, y: 0);
transform = transform.scaledBy(x: -1, y: 1);
}
// Now we draw the underlying CGImage into a new context, applying the transform
// calculated above.
let ctx: CGContext = CGContext(data: nil, width: Int(self.size.width), height: Int(self.size.height),
bitsPerComponent: self.cgImage!.bitsPerComponent, bytesPerRow: 0,
space: self.cgImage!.colorSpace!,
bitmapInfo: self.cgImage!.bitmapInfo.rawValue)!;
ctx.concatenate(transform)
if ( self.imageOrientation == .left ||
self.imageOrientation == .leftMirrored ||
self.imageOrientation == .right ||
self.imageOrientation == .rightMirrored ) {
ctx.draw(self.cgImage!, in: CGRect(x: 0.0,y: 0.0,width: self.size.height,height: self.size.width))
} else {
ctx.draw(self.cgImage!, in: CGRect(x: 0.0,y: 0.0,width: self.size.width,height: self.size.height))
}
// And now we just create a new UIImage from the drawing context and return it
return UIImage(cgImage: ctx.makeImage()!)
}
By Using
$("#txtEmail").val()
you get the actual value of the element
Here this should help you
The below jsfiddle link will help you understand how to rotate a image.I used the same one to rotate the dial of a clock.
var rotation = function (){
$("#image").rotate({
angle:0,
animateTo:360,
callback: rotation,
easing: function (x,t,b,c,d){
return c*(t/d)+b;
}
});
}
rotation();
Where: • t: current time,
• b: begInnIng value,
• c: change In value,
• d: duration,
• x: unused
No easing (linear easing): function(x, t, b, c, d) { return b+(t/d)*c ; }
The traditional approach is full of boilerplate code and clumsy resource handling. That's why I made the Spyglass framework. To demonstrate how it works, here's an example showing how to make a custom view that displays a String title.
Step 1: Create a custom view class.
public class CustomView extends FrameLayout {
private TextView titleView;
public CustomView(Context context) {
super(context);
init(null, 0, 0);
}
public CustomView(Context context, AttributeSet attrs) {
super(context, attrs);
init(attrs, 0, 0);
}
public CustomView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr, 0);
}
@RequiresApi(21)
public CustomView(
Context context,
AttributeSet attrs,
int defStyleAttr,
int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
init(attrs, defStyleAttr, defStyleRes);
}
public void setTitle(String title) {
titleView.setText(title);
}
private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
inflate(getContext(), R.layout.custom_view, this);
titleView = findViewById(R.id.title_view);
}
}
Step 2: Define a string attribute in the values/attrs.xml
resource file:
<resources>
<declare-styleable name="CustomView">
<attr name="title" format="string"/>
</declare-styleable>
</resources>
Step 3: Apply the @StringHandler
annotation to the setTitle
method to tell the Spyglass framework to route the attribute value to this method when the view is inflated.
@HandlesString(attributeId = R.styleable.CustomView_title)
public void setTitle(String title) {
titleView.setText(title);
}
Now that your class has a Spyglass annotation, the Spyglass framework will detect it at compile-time and automatically generate the CustomView_SpyglassCompanion
class.
Step 4: Use the generated class in the custom view's init
method:
private void init(AttributeSet attrs, int defStyleAttr, int defStyleRes) {
inflate(getContext(), R.layout.custom_view, this);
titleView = findViewById(R.id.title_view);
CustomView_SpyglassCompanion
.builder()
.withTarget(this)
.withContext(getContext())
.withAttributeSet(attrs)
.withDefaultStyleAttribute(defStyleAttr)
.withDefaultStyleResource(defStyleRes)
.build()
.callTargetMethodsNow();
}
That's it. Now when you instantiate the class from XML, the Spyglass companion interprets the attributes and makes the required method call. For example, if we inflate the following layout then setTitle
will be called with "Hello, World!"
as the argument.
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:width="match_parent"
android:height="match_parent">
<com.example.CustomView
android:width="match_parent"
android:height="match_parent"
app:title="Hello, World!"/>
</FrameLayout>
The framework isn't limited to string resources has lots of different annotations for handling other resource types. It also has annotations for defining default values and for passing in placeholder values if your methods have multiple parameters.
Have a look at the Github repo for more information and examples.
For Apache 2.4.2:
In httpd.conf:
Change
Require local
to
Require all granted
<asp:LinkButton ID="LinkButton1" runat="server" target="_blank">LinkButton</asp:LinkButton>
Use target="_blank" because It creates anchor markup. the following HTML is generated for above code
<a id="ctl00_ContentPlaceHolder1_LinkButton1" target="_blank" href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$LinkButton1','')">LinkButton</a>
div {
background: #dbdbdb;
-webkit-transition: .5s all;
-webkit-transition-delay: 5s;
-moz-transition: .5s all;
-moz-transition-delay: 5s;
-ms-transition: .5s all;
-ms-transition-delay: 5s;
-o-transition: .5s all;
-o-transition-delay: 5s;
transition: .5s all;
transition-delay: 5s;
}
div:hover {
background:#5AC900;
-webkit-transition-delay: 0s;
-moz-transition-delay: 0s;
-ms-transition-delay: 0s;
-o-transition-delay: 0s;
transition-delay: 0s;
}
This will add a transition delay, which will be applicable to almost every browser..
li = [0, 1, 2, 3]
for elem in li:
if (li.index(elem))+1 != len(li):
thiselem = elem
nextelem = li[li.index(elem)+1]
print 'thiselem',thiselem
print 'nextel',nextelem
else:
print 'thiselem',li[li.index(elem)]
print 'nextel',li[li.index(elem)]
Just append below property in your query and the first header or line int the record will not load or it will be skipped.
Try this
tblproperties ("skip.header.line.count"="1");
Since Java 8, you can use forEach() method from Iterable interface.
It's a default method. As an argument, it takes an object of class, which implements functional interface Consumer. You can implement Consumer locally in three ways:
With annonymous class:
houseAddress.forEach(new Consumer<String>() {
@Override
public void accept(String s) {
System.out.println(s);
}
});
lambda expression:
houseAddress.forEach(s -> System.out.println(s));
or by using method reference:
houseAddress.forEach(System.out::print);
This way of printing works for all implementations of Iterable interface.
All of them, gives you the way of defining how the elements will be printed, whereas toString() enforces printing list in one format.
The problem with your attempt at the psql
command line is the direction of the slashes:
newTestDB-# /i E:\db-rbl-restore-20120511_Dump-20120514.sql # incorrect
newTestDB-# \i E:/db-rbl-restore-20120511_Dump-20120514.sql # correct
To be clear, psql
commands start with a backslash, so you should have put \i
instead. What happened as a result of your typo is that psql
ignored everything until finding the first \
, which happened to be followed by db
, and \db
happens to be the psql
command for listing table spaces, hence why the output was a List of tablespaces. It was not a listing of "default tables of PostgreSQL" as you said.
Further, it seems that psql
expects the filepath
argument to delimit directories using the forward slash regardless of OS (thus on Windows this would be counter-intuitive).
It is worth noting that your attempt at "elevating permissions" had no relation to the outcome of the command you attempted to execute. Also, you did not say what caused the supposed "Permission Denied" error.
Finally, the extension on the dump file does not matter, in fact you don't even need an extension. Indeed, pgAdmin
suggests a .backup
extension when selecting a backup filename, but you can actually make it whatever you want, again, including having no extension at all. The problem is that pgAdmin
seems to only allow a "Restore" of "Custom or tar" or "Directory" dumps (at least this is the case in the MAC OS X version of the app), so just use the psql
\i
command as shown above.
Sending private message through api is now possible.
Fire this event for sending message(initialization of facebook object should be done before).
to:user
id of facebook
function facebook_send_message(to) {
FB.ui({
app_id:'xxxxxxxx',
method: 'send',
name: "sdfds jj jjjsdj j j ",
link: 'https://apps.facebook.com/xxxxxxxaxsa',
to:to,
description:'sdf sdf sfddsfdd s d fsf s '
});
}
Properties
app_id
Your application's identifier. Required, but automatically specified
by most SDKs.
redirect_uri
The URL to redirect to after the user clicks the Send or Cancel
buttons on the dialog. Required, but automatically specified by most
SDKs.
display
The display mode in which to render the dialog. This is automatically
specified by most SDKs.
to
A user ID or username to which to send the message. Once the dialog
comes up, the user can specify additional users, Facebook groups, and
email addresses to which to send the message. Sending content to a
Facebook group will post it to the group's wall.
link
(required) The link to send in the message.
picture
By default a picture will be taken from the link specified. The URL
of a picture to include in the message. The picture will be shown
next to the link.
name By default a title will be taken from the link specified. The name of the link, i.e. the text to display that the user will click on.
description
By default a description will be taken from the link specified.
Descriptive text to show below the link.

@VishwaKumar:
For sending message with custom text, you have to add 'message' parameter to FB.ui
, but I think this feature is deprecated. You can't pre-fill the message anymore. Though try once.
FB.ui({
method: 'send',
to: '1234',
message: 'A request especially for one person.',
data: 'tracking information for the user'
});
See this link: http://fbdevwiki.com/wiki/FB.ui
private Map<String, Integer> _map= new HashMap<String, Integer>();
Iterator<Map.Entry<String,Integer>> itr= _map.entrySet().iterator();
//please check
while(itr.hasNext())
{
System.out.println("key of : "+itr.next().getKey()+" value of Map"+itr.next().getValue());
}
There is no specialized image component provided in Swing (which is sad in my opinion). So, there are a few options:
Create in the window builder a JPanel, that will represent the location of the image. Then add your own custom image component to the JPanel using a few lines of code you will never have to change. They should look like this:
JImageComponent ic = new JImageComponent(myImageGoesHere);
imagePanel.add(ic);
where JImageComponent is a self created class that extends JComponent
that overrides the paintComponent()
method to draw the image.
Here is an example of getting the bounds using svg.getBox()
:
https://gist.github.com/john-doherty/2ad94360771902b16f459f590b833d44
At the end you get numbers that you can plug into the svg to set the viewbox properly. Then use any css on the parent div and you're done.
// get all SVG objects in the DOM
var svgs = document.getElementsByTagName("svg");
var svg = svgs[0],
box = svg.getBBox(), // <- get the visual boundary required to view all children
viewBox = [box.x, box.y, box.width, box.height].join(" ");
// set viewable area based on value above
svg.setAttribute("viewBox", viewBox);
You can try reusing your local Maven repository for Gradle:
Install the jar into your local Maven repository:
mvn install:install-file -Dfile=utility.jar -DgroupId=com.company -DartifactId=utility -Dversion=0.0.1 -Dpackaging=jar
Check that you have the jar installed into your ~/.m2/
local Maven repository
Enable your local Maven repository in your build.gradle
file:
repositories {
mavenCentral()
mavenLocal()
}
dependencies {
implementation ("com.company:utility:0.0.1")
}
I also encountered such an issue while trying to set up a project using Docker-Compose on Ubuntu.
The Docker had no access to internet at all, when I tried to ping any IP address or nslookup some URL - it failed all the time.
I tried all the possible solutions with DNS resolution described above to no avail.
I spent the whole day trying to find out what the heck is going on, and finally found out that the cause of all the trouble was the antivirus, in particular it's firewall which for some reason blocked Docker from getting the IP address and port.
When I disabled it - everything worked fine.
So, if you have an antivirus installed and nothing helps fix the issue - the problem could be the firewall of the antivirus.
If you want to fix vbs associations type
regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll
Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.
Big difference is functions and subs are both called using brackets rather than just functions.
So the compilers are installed on all computers with .NET installed.
See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.
First of all, two things that we need to understand,
bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"),
mServiceConn, Context.BIND_AUTO_CREATE);
here mServiceConn
is instance of ServiceConnection
class(inbuilt) it is actually interface
that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.
IBinder
Object. So, IBinder
object is our handler which accesses all the methods of Service
by using (.) operator. .
MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder binder) {
Log.d("ServiceConnection","connected");
myService = binder;
}
//binder comes from server to communicate with method's of
public void onServiceDisconnected(ComponentName className) {
Log.d("ServiceConnection","disconnected");
myService = null;
}
}
myservice.serviceMethod();
Here myService
is object and serviceMethod is method in service.
and by this way communication is established between client and server.
For those who are using this format all the timme like me I did an extension method. I just wanted to share because I think it can be usefull to you.
/// <summary>
/// Convert a date to a human readable ISO datetime format. ie. 2012-12-12 23:01:12
/// this method must be put in a static class. This will appear as an available function
/// on every datetime objects if your static class namespace is declared.
/// </summary>
public static string ToIsoReadable(this DateTime dateTime)
{
return dateTime.ToString("yyyy-MM-dd HH':'mm':'ss");
}
That should do the trick :
byte[] bytes = toByteArray(Str.toCharArray());
public static byte[] toByteArray(char[] array) {
return toByteArray(array, Charset.defaultCharset());
}
public static byte[] toByteArray(char[] array, Charset charset) {
CharBuffer cbuf = CharBuffer.wrap(array);
ByteBuffer bbuf = charset.encode(cbuf);
return bbuf.array();
}
You will have to iterate step by step into nested JSON.
for e.g a JSON received from Google geocoding api
{
"results" : [
{
"address_components" : [
{
"long_name" : "Bhopal",
"short_name" : "Bhopal",
"types" : [ "locality", "political" ]
},
{
"long_name" : "Bhopal",
"short_name" : "Bhopal",
"types" : [ "administrative_area_level_2", "political" ]
},
{
"long_name" : "Madhya Pradesh",
"short_name" : "MP",
"types" : [ "administrative_area_level_1", "political" ]
},
{
"long_name" : "India",
"short_name" : "IN",
"types" : [ "country", "political" ]
}
],
"formatted_address" : "Bhopal, Madhya Pradesh, India",
"geometry" : {
"bounds" : {
"northeast" : {
"lat" : 23.3326697,
"lng" : 77.5748062
},
"southwest" : {
"lat" : 23.0661497,
"lng" : 77.2369767
}
},
"location" : {
"lat" : 23.2599333,
"lng" : 77.412615
},
"location_type" : "APPROXIMATE",
"viewport" : {
"northeast" : {
"lat" : 23.3326697,
"lng" : 77.5748062
},
"southwest" : {
"lat" : 23.0661497,
"lng" : 77.2369767
}
}
},
"place_id" : "ChIJvY_Wj49CfDkR-NRy1RZXFQI",
"types" : [ "locality", "political" ]
}
],
"status" : "OK"
}
I shall iterate in below given fashion to "location" : { "lat" : 23.2599333, "lng" : 77.412615
//recieve JSON in json object
JSONObject json = new JSONObject(output.toString());
JSONArray result = json.getJSONArray("results");
JSONObject result1 = result.getJSONObject(0);
JSONObject geometry = result1.getJSONObject("geometry");
JSONObject locat = geometry.getJSONObject("location");
//"iterate onto level of location";
double lat = locat.getDouble("lat");
double lng = locat.getDouble("lng");
you cannot set this in javascript, you have to do this with html/css:
<style type="text/css" media="print">
@page { size: landscape; }
</style>
EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?
